When the external world takes place strong vibrations, remove seat 2 and can rock for the buffer seat, the buffer seat can rock for the fixing base, because friction mechanism can increase between buffer seat and the fixing base, the buffer seat with remove the frictional force between the seat, under friction mechanism's effect, can consume the power that removes seat and buffer seat fast to under canceling release mechanical system's effect, remove seat and buffer seat and resume to initial position, reach stable state. Compared with the prior art, the cultural relic exhibition stand provided by the invention gets rid of the traditional single damping mode, and the resetting mechanism and the friction mechanism are matched for use in the using process, so that the cultural relic exhibition stand can quickly damp and quickly restore to the original stable state.

specifically, as shown in fig. 2 and fig. 6, the fixed seat 1 is provided with a first slide rail assembly 11, and the buffer seat 3 is provided with a first slide block assembly 31 slidably connected to the first slide rail assembly 11. When the buffer base 3 moves relative to the fixed base 1, the first slide block assembly 31 moves along the first slide rail assembly 11, the first slide rail assembly 11 plays a guiding role in the movement of the buffer base 3, and the stable movement of the buffer base relative to the fixed base 1 is ensured.

The first slide rail assembly 11 may include one slide rail, or two or three slide rails. In at least one embodiment, as shown in fig. 2, the first slide rail assembly 11 includes two slide rails parallel to each other, and the slide rails extend along a first direction. The first slide assembly 31 may include one slide, or may include two, three, four, etc. slides. In at least one embodiment, as shown in fig. 2, when the first slide rail assembly 11 includes two slide rails parallel to each other, the first slide block assembly includes four slide blocks, two of the slide blocks are slidably connected to one slide rail, and the other two slide blocks are slidably connected to the other slide rail.

Specifically, as shown in fig. 3 and 7, the second slide rail assembly 21 is disposed on the moving seat 2, and the second slider assembly 32 slidably connected to the second slide rail assembly 21 is disposed on the buffer seat 3. When the movable seat 2 moves relative to the buffer seat 3, the second slide rail assembly 21 and the second slide block assembly 32 move relatively, so that the buffer seat is ensured to stably move relative to the fixed seat 1.

The second slide rail assembly 21 may include one slide rail, or two or three slide rails. In at least one embodiment, as shown in fig. 2, the second slide rail assembly 21 includes two slide rails parallel to each other, and the slide rails extend along a second direction, which is perpendicular to the first direction. The second slider assembly 32 may include one slider, or may include two, three, four, etc. sliders. In at least one embodiment, when the second slide rail assembly 21 includes two slide rails parallel to each other, the second slide block assembly 32 includes four slide blocks, two of the slide blocks are slidably connected to one slide rail, and the other two slide blocks are slidably connected to the other slide rail.

It should be noted that any structure capable of returning the movable seat 2 and the cushion seat 3 to the initial positions when a shock occurs may be the return mechanism 4 mentioned in the above embodiments. For example: the reset mechanism comprises a magnetic attraction adsorption piece and an adsorbed piece, or the reset mechanism comprises an elastic bolt line respectively connected with the fixed seat 1 and the movable seat 2, and the like.

In some embodiments, as shown in fig. 2 and 4, the reset mechanism 4 includes an attracted member 41 and an attracting member 42 attracting the attracted member 41, the attracting member 42 is disposed on the fixed base 1, and the attracted member 41 is disposed on the movable base 2. When the movable base 2 moves relative to the fixed base 1, the movable base 2 and the buffer base 3 are gradually restored to the initial positions under the suction of the suction member 42.

The adsorbing member 42 and the adsorbed member 41 can be magnetically attracted. Specifically, the adsorbing member 42 may be a magnet, the adsorbed member 41 may be an iron block, and the magnet on the fixed base 1 can adsorb the iron block on the movable base, so that the movable base 2 and the buffer base 3 can gradually return to the initial positions after the vibration.

On the basis of the above embodiment, the reset mechanism 4 may further include a fuse 44 connected to both the fixed base 1 and the movable base 2, and when the movable base 2 receives a vibration force greater than the strength of the fuse 44, the movable base 2 cuts the fuse 44. When the outside generates micro vibration which is far not enough to threaten the safety of the cultural relics, the fuse 44 can ensure that the movable seat 2 does not move relative to the fixed seat 1; when the vibration force applied to the movable base 2 is greater than the strength of the fuse 44, the movable base 2 has a strong tendency to move relative to the fixed base 1, the movable base 2 will cut off the fuse 44, and then the movable base 2 moves relative to the fixed base 1 to achieve the purpose of buffering the vibration. The setting of fuse 44 can be adjusted the historical relic stand and trigger buffering shock-absorbing state under the vibrations of big intensity, improves the practicality of above-mentioned historical relic stand, avoids removing seat 2 unnecessary and rocks.

Specifically, one fuse may be disposed between the fixed seat 1 and the movable seat 2, or two, three, four, or more fuses 44 may be disposed therebetween. In at least one embodiment, as shown in fig. 8, four fuses 44 are disposed between the fixed seat 1 and the movable seat 2, two fuses define the position of the movable seat 2 relative to the fixed seat 1 in the first direction, and the other two fuses define the position of the movable seat 2 relative to the fixed seat 1 in the second direction.

The fuse 44 may be made of lead wire, which has low hardness, and the movable seat is easy to cut off the fuse 44 when the external environment is severely vibrated.

It should be noted that, the fuse with the appropriate thickness can be selected according to the weight of the cultural relic. For example, when the weight of the cultural relic is heavy, the shock resistance effect is good, so the fuse 44 with the thickness being thick can be selected, and when the weight of the cultural relic is light, the shock resistance effect is weak, so the fuse 44 with the thickness being thin can be selected, so that the cultural relic exhibition stand can trigger the buffer shock absorption state in time.

in other embodiments, the reset mechanism 4 further includes a wire and a circuit board 43 disposed on the fixing base 1, the wire is connected to the circuit board 43, and the wire is wound around the outside of the adsorbing member 42, at this time, both the adsorbing member 42 and the adsorbed member 41 can be iron cores, after the wire is powered on, because the wire is wound around the iron cores, according to the electromagnetic principle, the adsorbing member 42 has magnetism, the adsorbing member 42 attracts the adsorbed member 41, and the moving base 2 and the buffer base 3 gradually recover to the initial position.

Wherein, above-mentioned canceling release mechanical system 4 can also be including locating the spirit level on fixing base 1, and the spirit level passes through the PLC controller to be connected with the circuit board, and the spirit level is used for sending swing angle signal to the PLC controller. When the fixed seat has strong vibration, the PLC controls the circuit board to be in a conducting state according to the swinging signal, so that the adsorption piece 42 has magnetism, and the adsorbed piece 41 is attracted; when the fixing seat is in weak vibration, the PLC does not control the circuit board according to the swing signal, and the circuit board is in a disconnected state at the moment, so that the adsorption piece 42 has no magnetism.

It should be noted that any structure capable of increasing the friction force between the buffer seat 3 and the fixed seat 1 and between the buffer seat 3 and the movable seat 2 can be the friction mechanism 5 mentioned in the above embodiments. For example: the friction means 5 may comprise two friction strips which are held tightly against each other, or the friction means 5 may comprise a friction strip and a clamping assembly for clamping the friction strip.

In some embodiments, as shown in fig. 3, the friction mechanism 5 includes a friction bar 51 and a clamping assembly 52, the friction bar 51 is connected to the fixed seat 1 or the movable seat 2, the clamping assembly 52 is disposed on the cushion seat 3, and the clamping assembly 52 clamps the friction bar 51.

When the clamping assembly 52 clamps the friction strip 51, a certain friction force exists between the clamping assembly 52 and the friction strip, and the friction force can slow down the vibration of the movable base 2 and the buffer base 3, so that the movable base 2 and the buffer base 3 are quickly stabilized to the initial state.

Specifically, as shown in fig. 2 and 3, the rubbing strip 51 is connected to the movable base 2, and the clamping unit 52 is disposed on the buffer base 3. As shown in fig. 3 in particular, the clamping assembly 52 has a clearance for the rub strip 51 to pass through, through which the clamping assembly 52 clamps the rub strip 51 to increase the friction between the moving seat 2 and the cushion seat 3.

in some embodiments, as shown in fig. 3, the clamping assembly 52 includes a first clamping piece 521, a second clamping piece 522, a first elastic piece 523, and a limiting link 524 disposed on the buffer seat 3, the first clamping piece 521, the second clamping piece 522, and the first elastic piece 523 are all sleeved on the limiting link 524, the limiting link 524 is used for limiting a distance between the first clamping piece 521 and the second clamping piece 522, a gap is formed between the first clamping piece 521 and the second clamping piece 522 for the friction strip 51 to pass through, and the first elastic piece 523 is used for enabling the first clamping piece 521 and the second clamping piece 522 to clamp the friction strip 51.

When the friction plate is used, one end of the first elastic piece 523 abuts against the limiting connecting rod 524, the other end of the first elastic piece 523 abuts against the second clamping piece 522, one end of the first clamping piece 521 abuts against the limiting connecting rod 524, and the other end of the first elastic piece is used for being matched with the second clamping piece 522 to clamp the friction strip 51. The clamping assembly is simple in structure, under the elastic action of the first elastic piece 523, the first clamping piece 521 and the second clamping piece 522 can stably clamp the friction strip 51, and the elastic force of the first elastic piece and the elastic force of the second clamping piece can be adjusted according to the required friction force during assembly, so that the application range is wider.

The material of the first clip 521 and the second clip 522 can be rubber, plastic, etc.

The limiting link 524 may be overlapped on the buffer base 3, or may be fixedly connected or detachably connected with the buffer base. When the limiting connecting rod 524 is lapped on the cushion seat 3, a groove for lapping the limiting connecting rod 524 is formed in the cushion seat 3, so that the limiting connecting rod 524 is prevented from moving relative to the cushion seat 3 along the moving direction of the friction strip 51; when the limit link 524 is fixedly connected or detachably connected to the cushion socket, the limit link 524 may be welded to the cushion socket 3 or detachably connected to the cushion socket 3 by a nut or a screw.

in other embodiments, the clamping assembly 52 may also include a second elastic member sleeved on the limiting link 524, one end of the second elastic member abuts against the limiting link 524, and the other end of the second elastic member abuts against the first clamping piece 521, so that the first clamping piece 521 presses the friction strip 51 against the first clamping piece 521, and the second elastic member cooperates with the first elastic member 523 to enable the first clamping piece 521 and the second clamping piece 522 to more stably clamp the friction strip 51.

In some embodiments, as shown in fig. 3, the limiting link 524 includes a connecting rod and two limiting members 5241 disposed on the connecting rod, and the first clamping piece 521 and the second clamping piece 522 are sleeved on the connecting rod. The two position-limiting members 5241 are used to limit the distance between the first clip piece 521 and the second clip piece 522, and the first clip piece 521 and the second clip piece 522 are sleeved on the connecting rod between the two position-limiting members 5241.

Specifically, the position-limiting member 5241 can be fixedly connected to the connecting rod, or detachably connected to the connecting rod. When the position-limiting member 5241 is detachably connected to the connecting rod, the position-limiting member 5241 and the connecting rod may be connected by a screw, a snap, or the like.

In at least one embodiment, the limiting member is a nut, and the nut is in threaded connection with the connecting rod.

In some embodiments, as shown in fig. 3, when the position-limiting members 5241 are detachably connected to the connecting rod, in order to more conveniently limit the position of the two position-limiting members 5241 relative to the connecting rod, the connecting rod includes a rod body 5242 and a position-limiting sleeve 5243 sleeved on the rod body 5242, the position-limiting sleeve 5243 is located between the two position-limiting members 5241, and the first clamping piece 521 and the second clamping piece 522 are sleeved on the position-limiting sleeve 5243. The two ends of the position-limiting sleeve 5243 respectively abut against the two position-limiting members 5241, so that the two position-limiting members 5241 are more stably screwed on the rod body 5242 to limit the distance between the first clamping piece 521 and the second clamping piece 522.

In some embodiments, as shown in fig. 3, the rubbing strip 51 has a sliding slot 511, the sliding slot 511 extends in a direction parallel to the moving direction of the rubbing strip 51, so as to prevent the sliding slot 511 from obstructing the movement of the rubbing strip 51, and the clamping assembly 52 penetrates through the sliding slot 511. The clamping assembly 52 penetrating the sliding slot 511 can prevent the rubbing strip 51 from being separated from the clamping assembly 52, so that the rubbing strip 51 is more stably clamped by the clamping assembly 52.

As shown in fig. 3, when the clamping assembly 52 includes the rod 5242 and the position-limiting sleeve 5243, the rod 5242 and the position-limiting sleeve 5243 jointly penetrate the sliding slot 511.

In some embodiments, as shown in fig. 2, in order to make the buffer seat 3 in an "i" shape, that is, a hollow structure is disposed at a position where the buffer seat does not need to be provided with other components, so as to effectively reduce the weight of the buffer seat 3, and facilitate the transportation of the above-mentioned cultural relic exhibition stand.
