Description

Technical Field

[0001] The utility model relates to the technical field of rubber O-rings, in particular to a rubber O-ring for an automobile air-conditioning compressor. Background Art

[0002] The automotive air-conditioning compressor is a key component of the automotive air-conditioning system. The automotive air-conditioning compressor is filled with refrigerant. If the refrigerant leaks, the air-conditioning cooling capacity will decrease or even fail. Therefore, the sealing requirements of each component are very high. Rubber O-rings are usually used in automotive air-conditioning compressors to achieve sealing.

[0003] However, it is difficult to disassemble a general rubber O-ring when in use, which will affect the subsequent replacement operation of the rubber O-ring. Therefore, the traditional rubber O-ring can be improved to avoid the above-mentioned problems. Utility Model Content

[0004] The utility model aims to solve the above problems and provides a rubber O-ring for an automobile air-conditioning compressor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rubber O-ring for an automobile air-conditioning compressor comprises a shell and a ring body, wherein the shell is provided with an annular groove for accommodating the ring body, a circular ring is slidably connected in the annular groove, a connecting groove is provided on the shell, and the connecting groove is connected to the annular groove, a handle slidably connected to the connecting groove is fixed on the circular ring, and the shell is provided with a limiting member for limiting the circular ring.

[0007] Preferably, the limiting member includes a round rod rotatably connected to the shell, and a side block is fixed to the end of the round rod, the shell outer shell is provided with a ring, and a clamping block slidably connected to the connecting groove is fixed on the ring, the ring is provided with a through hole slidably connected to the round rod and the side block, the ring is provided with a groove connected to the through hole, and when the side block is rotated to abut against the inner bottom wall of the groove, the side block cannot be slidably connected to the through hole.

[0008] Preferably, the block is slidably connected to the outer wall of the ring body.

[0009] Preferably, an elastic gasket protrudes from the portion where the circular ring abuts against the annular groove.

[0010] Preferably, an anti-slip pad is provided on the portion where the side block is slidably connected to the groove.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The present application is to remove the ring from the shell by applying force upwards through the handle so that the ring moves upwards with the handle, and the ring body is pushed out of the annular groove until the ring body is out of the annular groove. The disassembly of the ring body is completed, and the operation is relatively convenient. The staff can quickly take the ring body out of the annular groove, eliminating cumbersome steps.

[0013] 2. In the present application, when the side block and the round rod pass through the round hole and the side block is located in the groove, the side block can be rotated at this time to make the lower surface of the side block slidably connected with the inner bottom wall of the groove. At this time, the side block cannot be retracted into the through hole under force, and force can only be applied to make the side block slidably connected with the through hole until the side block is rotated to align with the through hole.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] The utility model provides a technical solution, please refer to Figure 1-3 :

[0022] A rubber O-ring for an automobile air-conditioning compressor comprises a housing 1 and a ring body 6. The housing 1 is provided with an annular groove 2 for accommodating the ring body 6. A circular ring 4 is slidably connected in the circular groove 2. An elastic gasket protrudes from the portion where the circular ring 4 abuts against the circular groove 2. The housing 1 is provided with a connecting groove 3, which is connected to the circular groove 2. A handle 5 slidably connected to the connecting groove 3 is fixed on the circular ring 4. The housing 1 is provided with a limiting member for limiting the position of the circular ring 4. By applying force to the handle 5, the circular ring 4 can be moved upward in the circular groove 2, thereby pushing the ring body 6 out of the circular groove 2, making it convenient for the staff to take the ring body 6 out of the circular groove 2, which is more convenient and quick, and saves cumbersome steps.

[0023] Embodiment 2:

[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limiting member includes a round rod 11 rotatably connected to the housing 1, and a side block 12 is fixed to the end of the round rod 11, a collar 7 is provided on the outer shell of the housing 1, and a clamping block 8 slidably connected to the connecting groove 3 is fixed on the collar 7, and the clamping block 8 is slidably connected to the outer wall of the ring body 6, a through hole 9 slidably connected to the round rod 11 and the side block 12 is provided on the collar 7, and a groove 10 connected to the through hole 9 is provided on the collar 7, and a non-slip pad is provided on the part where the side block 12 is slidably connected to the groove 10, and when the side block 12 is rotated to abut against the inner bottom wall of the groove 10, the side block 12 cannot be slidably connected to the through hole 9, that is, the side block 12 cannot be retracted into the through hole 9 under force. By rotating the side block 12, the side block 12 can play a limiting effect on the collar 7, resulting in the collar 7 being unable to separate from the housing 1, so the collar 7 can stably play a limiting role on the ring 4, so that the ring 4 cannot be forced to move upward even under the action of the handle 5.

[0025] In summary, when the inner ring body 6 of the annular groove 2 of the housing 1 needs to be removed, the side block 12 can be rotated so that the side block 12 rotates together with the round rod 11 until the side block 12 rotates to align with the through hole 9. At this time, the ferrule 7 can be lifted upward until the ferrule 7 is removed from the housing 1. Then, the handle 5 is used to apply force upward so that the ring 4 moves upward with the handle 5, and the ring body 6 is pushed out from the annular groove 2 until the ring body 6 is separated from the annular groove 2, and the removal of the ring body 6 is completed.

[0026] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
