Description
Technical Field
[0001] The utility model relates to the technical field of sleeve air springs, in particular to a sleeve air spring with a novel modular buckle design. Background Art
[0002] There are mainly three types of air springs: bladder type, diaphragm type and sleeve type. Sleeve air springs are mainly used in the elastic elements (i.e., air springs or other springs) of the cab suspensions of sedans, medium trucks and heavy trucks, which play a core role in the comfort of drivers.
[0003] The existing sleeve air springs mainly compress metal rings through a tube press device to fix the leather bag on the parts for sealing. When the pressure of the metal ring on the fixed leather bag is too large, the film bag will be damaged. When the pressure of the metal ring on the fixed leather bag is too small, the leather bag cannot be completely sealed, making it difficult to control the sealing performance of the leather bag. Therefore, a device for stably sealing the leather bag is needed to seal the leather bag. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a sleeve air spring with a novel modular buckle design to solve the problem that the existing sleeve air springs mainly compress metal rings through a tube press device to fix the leather bag on the parts for sealing. When the pressure of the metal ring on the fixed leather bag is too large, the film bag will be damaged. When the pressure of the metal ring on the fixed leather bag is too small, the leather bag cannot be completely sealed, making it difficult to control the sealing performance of the leather bag as mentioned in the above background art.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a sleeve air spring with a novel modular buckle design, including:
[0007] A housing assembly, the housing assembly includes a housing;
[0008] A movable assembly, the movable assembly includes a connecting rod, a buckle and an elastic block;
[0009] The connecting rod is sleeved on the outer surface of the housing, the buckle is fixedly connected to the inner side surface of the connecting rod, and the elastic block is fixedly connected to the inner position of one end of the connecting rod.
[0010] Further, the housing assembly further includes a fixing groove and a convex block;
[0011] The fixing groove is opened at the inner position of one end of the housing, and the convex block is fixedly connected to the outer surface position of the other end of the housing.
[0012] Further, the housing is of a T-shaped structure, and the buckle is located inside the fixing groove.
[0013] Further, the elastic block is located outside the convex block, and the outer end of the elastic block is in contact with the outer end of the convex block.
[0014] Further, it also includes a leather bag;
[0015] Both sides of one end of the leather bag are respectively in contact with the outer surface of the housing and the inner surface of the connecting rod.
[0016] Compared with the prior art, the advantages of the present utility model are as follows:
[0017] In the present utility model, by setting an active component, the leather bag is sleeved on the outer surface of the housing, and the outer end of the leather bag is placed outside the fixing groove. Then, the connecting rod is sleeved on the outer surfaces of the housing and the leather bag, and by applying a thrust to the connecting rod, the elastic block moves outward under the limitation of the convex block, causing the elastic block to deform outward and move along the direction of the convex block. When the elastic block moves to the outer end of the convex block, the elastic block returns to its original shape under the elastic action, making the outer end of the elastic block in contact with the outer end of the convex block. The convex block limits the elastic block, and the connecting rod drives the buckle and the outer end of the leather bag into the fixing groove, so that the inner surface of the connecting rod and the outer surface of the housing squeeze and clamp the leather bag, thereby fixing and sealing the leather bag. Since the connecting rod and the housing have the same size, the leather bag can be stably sealed. Description of the Drawings

[0026] Please refer to Figure 1 As shown, this embodiment is a sleeve-type air spring with a novel modular buckle design, including:
[0027] A housing assembly, the housing assembly includes an outer shell 1;
[0028] A movable assembly, the movable assembly includes a connecting rod 4, a buckle 5, and an elastic block 6;
[0029] The connecting rod 4 is sleeved on the outer surface of the outer shell 1, the buckle 5 is fixedly connected to the inner side surface of the connecting rod 4, and the elastic block 6 is fixedly connected to the inner position of one end of the connecting rod 4;
[0030] The connecting rod 4 is used to support the buckle 5 and the elastic block 6, and the connecting rod 4 can squeeze the outside of the airbag 7. The buckle 5 is used to drive the outer end of the airbag 7 to move, and the elastic block 6 is used to limit the connecting rod 4;
[0031] The housing assembly further includes a fixing groove 2 and a convex block 3;
[0032] The fixing groove 2 is opened at the inner side position of one end of the outer shell 1, and the convex block 3 is fixedly connected to the outer surface position of the other end of the outer shell 1;
[0033] The outer shell 1 is used to support the airbag 7, the connecting rod 4, and the convex block 3. The fixing groove 2 is used to limit the buckle 5, and the convex block 3 is used to limit the elastic block 6;
[0034] The outer shell 1 is of a T-shaped structure, and the buckle 5 is located inside the fixing groove 2;
[0035] The airbag 7 can be sleeved on the outer surface position of one end of the outer shell 1, and the outer end of the airbag 7 is located outside the fixing groove 2;
[0036] The elastic block 6 is located outside the bump 3, and the outer ends of the elastic block 6 and the bump 3 are in contact with each other;
[0037] When the elastic block 6 moves along the bump 3, the elastic block 6 is blocked by the bump 3 and undergoes elastic deformation. When the outer end of the elastic block 6 is not blocked by the bump 3, the elastic block 6 returns to its original shape under the elastic action, and the outer end of the elastic block 6 is blocked by the outer end of the bump 3;
[0038] The leather bag 7;
[0039] Both sides at one end of the leather bag 7 are respectively in contact with the outer surface of the housing 1 and the inner surface of the connecting rod 4;
[0040] The leather bag 7 is used to store compressed gas and seal the compressed gas;
[0041] Working principle: When it is necessary to seal the leather bag 7, the leather bag 7 is sleeved on the outer surface of one end of the housing 1, and the outer end of the leather bag 7 is placed outside the fixing groove 2. Then the connecting rod 4 is sleeved on the outer surface of the housing 1, and a force for moving is applied to the connecting rod 4 to make the connecting rod 4 move towards the leather bag 7. When the connecting rod 4 moves, it drives the buckle 5 and the elastic block 6 to move towards the leather bag 7. The movement of the buckle 5 drives the outer end of the leather bag 7 to move. When the buckle 5 and the outer end of the leather bag 7 move into the fixing groove 2, the outer end of the leather bag 7 is fixed inside the housing 1, and the elastic block 6 moves along the direction of the bump 3. The elastic block 6 undergoes elastic deformation outward under the action of the bump 3. Continue to move the elastic block 6. When the outer end of the elastic block 6 is not blocked by the bump 3, the elastic block 6 returns to its original shape under the elastic action, so that the outer ends of the elastic block 6 and the bump 3 are in contact with each other. The bump 3 limits the outer end of the elastic block 6, so that the elastic block 6 is fixed at the outer end of the bump 3, and then the connecting rod 4 can be fixed at the outer surface position of the housing 1. And when the connecting rod 4 is located outside the housing 1, the leather bag 7 is located between the inner side of the connecting rod 4 and the outer side of the housing 1, so that the connecting rod 4 and the housing 1 squeeze the leather bag 7, thereby fixing the leather bag 7 between the connecting rod 4 and the housing 1. And the distance between the connecting rod 4 and the housing 1 is fixed, and the distance between the connecting rod 4 and the housing 1 remains fixed, so that the leather bag 7 is stably sealed by the connecting rod 4 and the housing 1.
