The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The inventor finds that the sealing ring is frequently used in the sealing connection structure of the intelligent terminal device in the research of the sealing connection structure of the intelligent terminal device, and the sealing ring is aged and deformed after being used for a long time, so that the interference amount of the sealing ring is reduced. Meanwhile, the material of the sealing ring can change physical properties under the influence of severe environment for a long time, the elasticity is reduced due to the corrosion of the external environment, and finally the friction resistance caused by the interference of the sealing ring is reduced, so that the faults of structural part loosening, fixing or rotating function failure, sealing failure and the like are caused.

Based on this, referring to fig. 1 to 6, the present embodiment provides a sealing connection structure, which includes a first connector 1, a second connector 3, a sealing ring 2 and a spring 4.

The first connection head 1 is provided with a first region 17, a second region 18, a first flange 11 and a second flange 12. The first flange 11 and the second flange 12 are each arranged around the periphery of the first connection head 1, the first flange 11 being connected to the second flange 12, the second region 18 being arranged between the first region 17 and the first flange 11.

The sealing ring 2 is arranged around the first flange 11. The first flange 11 of the first joint 1 has a length in the radial direction larger than that of the second flange 12, and the first flange 11 and the second flange 12 are provided in a stepped shape having different heights so that the seal ring 2 provided around the first flange 11 can abut against the second flange 12. The second flange 12 of the first connector 1 is thicker than 0.1mm in the axial direction, so that the structural strength of the second flange 12 is guaranteed, and the damage caused by extrusion is avoided, and the service life of the first connector 1 is not affected. After the first connector 1 and the second connector 3 are assembled, the second flange 12 plays a limiting role in the sealing ring 2, the second connector 3 is favorable for compressing the sealing ring 2, and the sealing interference amount of the sealing ring 2 is adjusted according to the degree of compressing the sealing ring 2.

The second connector 3 is provided with a second connecting portion 31, and the first connecting portion 13 is matched with the second connecting portion 31 to enable the second connector 3 to press the sealing ring 2.

The interference amount of the sealing ring 2 of the sealing connection structure can be adjusted through the connection tightness degree of the first connector 1 and the second connector 3, so that after the sealing ring 2 is used for a long time, the interference amount can be improved by changing the connection tightness degree of the first connector 1 and the second connector 3, namely, the first connector 1 is screwed down relative to the second connector 3 again, the sealing ring 2 sleeved on the first connector 1 can be compressed again, the sealing performance and the waterproof performance of the aged or loosened sealing ring 2 after long-term use can be improved, meanwhile, the problem that the sealing connection structure is loosened after long-term use is solved, parts are prevented from being disassembled and replaced, the later maintenance cost is reduced, the structure is simple, and the operation is convenient.

The spring 4 is sleeved on the second area 18 of the first connector 1, a through hole 32 is arranged inside the second connector 3, and the internal thread is arranged on the through hole 32 of the second connector 3. The through hole 32 of the second connector 3 is further provided with a spring baffle 33. The spring baffle 33 is arranged around the inner side wall of the through hole 32 of the second connector 3 and used for abutting against the spring 4 to limit the spring 4.

After the first connector 1 and the second connector 3 are assembled by the first connecting portion 13 and the second connecting portion 31, one end of the spring 4 abuts against the spring stop 33 of the second connector 3, and the other end abuts against the first flange 11 of the first connector 1. The thickness of the first flange 11 of the first connector 1 in the axial direction is larger than 0.1mm, so that the structural strength of the first flange 11 is guaranteed, and the damage during extrusion is avoided, and the service life of the first connector 1 is influenced. Along with the first connector 1 and the second connector 3 are matched and connected, the first connector 1 and the second connector 3 continuously compress the spring 4 and the sealing ring 2. Spring 4 is compressed at this in-process atress for spring 4 exerts opposite direction's elastic force to first connector 1 and second connector 3, and this elastic force increases the frictional force between the cooperation of first connector 1 and second connector 3, and then prevents that first connector 1 and second connector 3 cooperation back are not hard up, guarantees that first connector 1 and second connector 3 can not twist easily, rotate and drop, realizes the effect of auto-lock to first connector 1 and second connector 3.

In this embodiment, the thickness of the cross section of the thread of the external thread of the first connector 1 is greater than or equal to 0.7mm, the upper and lower surfaces of the thread are extracted by 5 degrees, and the pitch of the thread is 1.5 mm. The thickness of the cross section of the thread of the internal thread of the second connector 3 is more than or equal to 0.75mm, the upper and lower surfaces of the thread are subjected to die drawing by 5 degrees, and the distance between the threads is 1.4 mm. Secondly, the larger the thread meshing area of the external thread and the internal thread is, the better the sealing effect of the sealing connection structure is.

The sealing ring 2 is made of silica gel or TPU (Thermoplastic polyurethanes) which is named as Thermoplastic polyurethane elastomer rubber and has the excellent characteristics of high tension, high tensile force, toughness and aging resistance. In order to improve the sealing effect of the sealing ring 2, a third flange 21 is arranged on the periphery of the sealing ring 2, and the third flange 21 is arranged around the sealing ring 2. In this embodiment, the third flange 21 is raised 0.1mm for sealing, and the hardness of silica gel circle adopts 30 degrees, can play better sealed effect.

The axial length of the sealing ring 2 is greater than that of the first flange 11, so that when the second connector 3 is assembled with the first connector 1, the sealing ring 2 can be continuously extruded when the second connector 3 abuts against the sealing ring 2, and the sealing interference amount of the sealing ring 2 is adjusted and increased. When sealing washer 2 is ageing or use the back not hard up for a long time promptly, through screwing first connector 1 and second connector 3 and can increase the sealed interference volume of sealing washer 2, improve sealed effect and waterproof performance, solved the not hard up problem of sealing connection structure, avoided dismantling the renewal part, reduced later stage cost of maintenance.

When sealing washer 2 is in not receiving the extrusion force under the free state, the axial length of sealing washer 2 is a with the axial length difference of first flange 11, and the external screw thread closes the length with the internal thread soon and is b, closes the length soon and is the connection length of double-phase mating thread, satisfies: b is more than or equal to a. The sealing ring 2 can be tightly pressed by the screwing length which is long enough when the first connector 1 and the second connector 3 are assembled.

In the embodiment, a is more than or equal to 0.5mm and less than or equal to 1.0mm, when the first connecting joint 1 is screwed down, two sides of the sealing ring 2 are compressed by external force, and the middle part of the sealing ring 2 deforms to bulge, so that the interference amount of the sealing ring 2 and an external matched structural part is increased, the interference amount is adjustable, and the operation is simple and convenient.

The end surface of the first connector 1 near the second connector 3 is provided with a handle 15, so that a user can rotate the handle 15 of the first connector 1 through the through hole 32 of the second connector 3. The user rotates the handle 15 of first connector 1 and can screw up first connector 1 and second connector 3 to make sealing washer 2 more tight by extrusion, and then improve sealed and water-proof effects, solved the not hard up problem of sealing connection structure.
