Technical Field

The invention relates to a door stopper, in particular to an adjustable buffer type door stopper.

Background

When the door is opened or closed by wind or force, the door is large in inertia, if the door cannot be decelerated in time after reaching a limited position, the mechanical limiting device is impacted, large noise is generated, and the problems of deformation of the door, shattering of glass on the door and the like can be caused by impact.

Based on the above problems, chinese patent No. CN206091659U discloses an automatic damping-changing buffering and damping door stopper device based on eddy current braking, which includes an eddy current damping tube, a magnet and its supporting structure, and a terminal buffering and fixing device, wherein the magnet is connected with the supporting structure, and the terminal buffering and fixing device is connected with the terminal inner portion of the eddy current damping tube.

The device utilizes the eddy current braking principle, and the principle is as follows: according to Faraday's law of electromagnetic induction, when a conductor is in a changing magnetic field or moves relative to the magnetic field, the magnetic flux passing through any loop of the conductor can change, induction current is generated in the process of changing the magnetic flux to form eddy current, and the magnetic field formed by the induction eddy current tries to block the sudden change of the magnetic flux, so that damping effect is generated to form braking effect. The faster the relative motion speed, the stronger the damping, and when the speed is reduced, the damping is weakened, and the damping effect can be automatically changed according to the speed. Therefore, the above prior art applies the eddy current braking principle to the door stopper to achieve a good buffering effect and control the impact, vibration, noise, etc. during the opening and closing of the door.

However, the vortex damping tube in the conventional patent is fixed in length, and is applicable only to a damping effect in either a low wind speed or a high wind speed, and cannot simultaneously achieve damping in both a low wind speed and a high wind speed. This is because the longer the length of the eddy current damping tube is, the longer the time for the magnet to pass through the eddy current damping tube becomes, and the longer the damping maintaining time for the magnet becomes. If the length of the eddy damping tube is too long, under the condition of low wind speed, the magnet is likely to be difficult to penetrate through the eddy damping tube to be attracted with the tail end buffering and fixing device; when the length of the vortex damping tube is small, although the buffering requirement under the condition of low wind speed can be met, the buffering requirement under the condition of high wind speed still cannot be met, so that the door is deformed due to impact, and glass on the door is shattered. Because coastal areas are full of typhoon attack in summer for a long time, the wind power of the typhoon reaches 12 grades or above, and high wind power needs to be braked by using vortex damping pipes with longer length, the danger avoiding mechanism of the door panel under the condition of sudden high wind speed is especially important.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 11, an adjustable buffer door stopper includes a hinge base 1, a sliding base 2, a telescopic eddy current damping tube assembly 3 and an iron pile 4, the hinge base 1 is disposed on a door panel 5, and the sliding base 2, the telescopic eddy current damping tube assembly 3 and the iron pile 4 are sequentially disposed on a wall. The sliding seat 2 and the telescopic eddy current damping tube assembly 3 are connected with the same sliding rod 6 in a sliding mode. One end of the sliding rod 6 close to the iron pile 4 is provided with a powerful magnetic steel 7, the other end of the sliding rod is hinged with a connecting rod 8, and one end of the connecting rod 8 departing from the sliding rod 6 is hinged with the hinge base 1.

Telescopic eddy current damping tube subassembly 3 is including being used for being fixed in mount pad 9 on the wall, and one side that mount pad 9 deviates from the wall is provided with flexible cover seat 10, and the inner wall horizontal sliding connection of flexible cover has telescopic tube 11, and telescopic tube 11 inner wall horizontal sliding connection has sliding sleeve 12. A sliding block 13 is arranged on one side of the sliding sleeve 12 facing the mounting seat 9, and a sliding rail 14 for the sliding block 13 to slide is horizontally arranged on the mounting seat 9. The slider 13 is provided with a locking mechanism 15 which can lock the slider 13 and the slide rail 14 to limit the position of the slide sleeve 12, and the locking mechanism 15 is electrically connected with an air velocity sensor 16 arranged on the door panel 5. One side of the sliding sleeve 12 is provided with a spring 17 which can provide sliding power for the sliding sleeve 12, and the other end of the spring 17 is connected with the mounting seat 9. The mounting base 9 is further provided with an adjusting mechanism 18 for adjusting the sliding speed of the telescopic tube 11 by adjusting the compression degree of the spring 17.

When in actual use, the rotation of door plant 5 can drive 1 displacement of hinge seat and change, and then drives 8 synchronous motion of connecting rod, and connecting rod 8 drives slide bar 6 this moment and slides along slide seat 2 and 3 inner walls of flexible vortex damping pipe assembly, and slide bar 6 drives powerful magnet steel 7 and slides at 3 inner walls of flexible vortex damping pipe assembly simultaneously to powerful magnet steel 7 is close to iron pile 4 gradually.

Meanwhile, when the strong magnetic steel 7 passes through the telescopic eddy current damping pipe assembly 3, an eddy current damping effect is generated in the telescopic eddy current damping pipe assembly 3. And door plant 5 closes the speed faster, and the sliding speed of slide bar 6 is faster, and the eddy current magnetic resistance intensity that powerful magnet steel 7 produced at flexible eddy current damping tube subassembly 3 is big more simultaneously, consequently can effectual reduction door plant 5's slew velocity to reduce door plant 5's slew velocity to minimumly. When the strong magnetic steel 7 passes through the telescopic eddy current damping tube assembly 3, the strong magnetic steel 7 can be stably adsorbed on the iron pile 4.

Because the length of the telescopic eddy current damping tube assembly 3 is adjustable, when the wind speed sensor 16 detects that 12-level or more than 12-level strong wind blows, an electric signal is transmitted to the locking mechanism 15 to unlock the slide block 13 and the slide rail 14. At this time, the spring 17, which is originally in a compressed state, provides power required for sliding the sliding sleeve 12 under the action of elastic potential energy of the spring, so that the sliding sleeve 12 slides along the axial direction thereof, thereby achieving the purpose of extending the vortex damping tube. Wherein, the adjusting mechanism 18 can adjust the compression of the spring 17 and further adjust the sliding distance and the sliding speed of the sliding sleeve 12. If the length of the telescopic eddy current damping tube assembly 3 is longer, the longer the resistance maintaining time is, and the more obvious the speed reducing effect of the door panel 5 is, so that the telescopic eddy current damping tube assembly can be used under the condition of typhoon or strong wind above 12 grades, has the risk avoiding effect and can protect the door panel 5.

When the length of the eddy damping tube is not adjustable, the eddy damping tube is fixed. If the length is small, the wind-driven generator can meet the use requirement in most time (such as no wind or low wind speed condition), but can not meet the requirement of sudden high wind speed condition. If the length is longer, the wind-resistant safety door can be suitable for use requirements under the condition of high wind speed, but because the length is too long, the resistance maintaining time is longer, and under the condition of no wind or low wind speed, the strong magnetic steel 7 is probably difficult to penetrate through the telescopic eddy current damping pipe assembly 3 to be attracted with an iron column, so that the problem that the door panel 5 is prevented from being damaged under the condition of high wind speed is solved, and the arrangement of a risk avoiding mechanism is particularly important.

Further, the sliding seat 2 comprises a long strip-shaped seat plate 19, a pair of sliding pipes 20 are horizontally arranged on the seat plate 19 side by side, and the inner walls of the sliding pipes 20 are provided with ceramic inner cores 21 which abut against the outer wall of the sliding rod 6. When slide bar 6 slided in sliding seat 2, the inner wall of pottery inner core 21 contradicts slide bar 6's outer wall, reduces the frictional force between sliding seat 2 and the slide bar 6 through setting up pottery inner core 21 this moment for slide bar 6's slip process is more smooth, thereby avoids slide bar 6 to appear blocking the phenomenon.

Further, the outer walls of the ends of the telescopic sleeve 11 and the sliding sleeve 12 close to the telescopic sleeve seat 10 are provided with outer edges 22, and the ends of the telescopic sleeve seat 10 and the telescopic sleeve 11 close to the sliding sleeve 12 are provided with inner edges 23 for abutting against the outer edges 22.

Furthermore, the adjusting mechanism 18 includes a push plate 24 connected to one end of the spring 17, a cam 25 capable of shifting the push plate 24 to move toward or away from the spring 17 is disposed at one end of the push plate 24 away from the spring 17, and the cam 25 is rotatably connected to the mounting base 9. A fastener 26 for limiting the rotational position of the cam 25 is further provided on one side of the cam 25. By adjusting the rotating position of the cam 25, the displacement of the push plate 24 contacting with the cam 25 is adjusted, so that the push plate 24 moves towards or away from the spring 17, and the compression degree of the spring 17 is adjusted. After the adjustment is completed, the position of the cam 25 is fixed by the fastener 26.

Further, the locking mechanism 15 includes a rotating shaft 27, a cavity 28 is disposed inside the slider 13, and the rotating shaft 27 is horizontally rotatably connected in the cavity 28. A locking plate 29 is arranged at one end of the rotating shaft 27 in the cavity 28, a locking rod 30 is hinged on the outer wall of the locking plate 29, and an abdicating groove 31 which can facilitate the rotation of the locking rod 30 is arranged on the locking plate 29. The upper end face of the sliding block 13 is provided with a square hole 32 through which the locking rod 30 can penetrate, and the inner wall of the sliding rail 14 is provided with a locking groove 33 which can be matched with the locking rod 30. One end of the rotating shaft 27 outside the slider 13 is provided with a micro servo motor 34 capable of driving the rotating shaft 27 to rotate, and the micro servo motor 34 is electrically connected with the wind speed sensor 16.

In actual use, the rotation of the rotating shaft 27 will drive the hinged locking rod 30 to change in position and height, and the change in height will bring about whether the locking rod 30 is exposed out of the square hole 32 and is engaged with the locking groove 33 on the slide rail 14. Specifically, the following are mentioned: the cross-sectional area of the square hole 32 and the locking groove 33 as described herein is required to be larger than that of the locking lever 30. The length direction of the square hole 32 and the locking groove 33 is required to be consistent with the rotation direction of the rotating shaft 27.

According to the wind speed sensor, when the wind speed sensor 16 detects that 12 or more levels of strong wind attack on the outside, an electric signal is transmitted to the micro servo motor 34, and the micro servo motor 34 controls the rotating shaft 27 to rotate by a corresponding angle, so that the locking rod 30 is hidden in the square hole 32. At this time, the sliding sleeve 12 is driven to move under the action of the spring 17 so as to increase the length of the telescopic eddy current damping tube group, thereby being used under the condition of adapting to the wind speed of 12 grades or more.
