Description

Technical Field

[0001] The utility model relates to the technical field of joint assemblies, in particular to an assembled self-locking damping plastic joint assembly. Background Art

[0002] The plastic self-locking damping joint is one of the important components of the shift cable. It is usually used at the operating mechanism end of the shift push-pull cable to connect the cable and the shifter.

[0003] Currently, most of the existing damping plastic joints are fixed by threads. Since the joints are often in a vibrating environment during daily use, the thread fixing effect is poor and they are easy to loosen after a long time of use. Therefore, after the joint threads are installed, glue is needed to assist in bonding, which increases the production process and the product manufacturing cost. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0006] A self-locking damping plastic joint assembly comprises a connector, a limited position fixedly connected at the edge of the outer wall of the connector, an external trapezoidal thread arranged at the end of the connector, a guide tube penetrating the interior of the connector, a rear support ring arranged on the outer wall of the guide tube, a rubber shockproof ring arranged between the rear support ring and the inner side of the connector, a metal connector arranged at one end of the rear support ring away from the connector, a fixing seat arranged outside the metal joint, and a back-stop groove arranged at the outer edge of one end of the fixing seat close to the connector.

[0007] As a preferred solution for assembling a self-locking damping plastic joint assembly described in the utility model, an internal trapezoidal thread matching the external trapezoidal thread is provided inside the fixing seat, and the connecting head is correspondingly threadedly connected to the fixing seat, so as to facilitate the corresponding assembly of the fixing seat and the connecting head into one body.

[0008] As a preferred solution for assembling a self-locking damping plastic joint assembly described in the utility model, the limit point corresponds to the position of the anti-recession groove. When the fixing seat and the connecting head are connected, the limit point is conveniently stuck in the anti-recession groove. At this time, the two parts are not easy to loosen. If the two parts need to be separated, the connecting head can be unscrewed by simply moving the limit point on the connecting head out of the anti-recession groove of the fixing seat.

[0009] As a preferred solution for the self-locking damping plastic joint assembly described in the utility model, the connecting head, the fixing seat and the guide tube are all made of alloy plastic materials, and all three are made by injection molding. The products are mass-produced through molds, and have good size, temperature and consistency.

[0010] As a preferred solution for assembling a self-locking damping plastic joint assembly described in the utility model, the outer diameter of the connecting head near the limit point is consistent with that of the fixing seat near the anti-recession groove. After the connecting head and the fixing seat are installed and docked, the outer surface of the docking point is smooth and uniform, not easily affected by external forces, thereby improving the stability of the limit point in the anti-recession groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model makes it easier to assemble parts and saves time by cooperating with the connecting head, the fixing seat and the anti-retraction groove. The anti-retraction groove structure is added to effectively prevent the product from loosening during circulation and has a certain error-proofing function. At the same time, it also eliminates the need for glue to be used for bonding due to poor thread fixation, reduces the number of working steps, and is also conducive to reducing product manufacturing costs.

[0022] See also Figure 1-4 The utility model provides an assembled self-locking damping plastic joint assembly, including a connector 1, a fixed connection limited position 8 at the edge of the outer wall of the connector 1, an outer trapezoidal thread 9 is arranged at the end of the connector 1, a guide tube 2 is arranged inside the connector 1, a rear support ring 4 is arranged on the outer wall of the guide tube 2, a rubber shockproof ring 3 is arranged between the rear support ring 4 and the inner side of the connector 1, a metal connector 5 is arranged at the end of the rear support ring 4 away from the connector 1, and a fixing seat 6 is arranged outside the metal connector 5,

[0023] The fixing seat 6 is provided with an internal trapezoidal thread matching the external trapezoidal thread 9 , and the connector 1 is correspondingly threadedly connected to the fixing seat 6 , so that the fixing seat 6 and the connector 1 can be assembled into one body.

[0024] A backstop groove 7 is provided at the outer edge of one end of the fixing seat 6 close to the connecting head 1, and the limit point 8 corresponds to the position of the backstop groove 7. When the fixing seat 6 and the connecting head 1 are connected, the limit point 8 is convenient for being stuck in the backstop groove 7. At this time, the two parts are not easy to loosen. If the two parts need to be separated, just move the limit point 8 on the connecting head 1 out of the backstop groove 7 of the fixing seat 6 to unscrew the connecting head 1.

[0025] In this embodiment, the outer diameter of the connector 1 near the limit point 8 is consistent with that of the fixing seat 6 near the anti-recession groove 7. After the connector 1 and the fixing seat 6 are installed and docked, the outer surface of the docking point is smooth and uniform, and is not easily affected by external forces, thereby improving the stability of the limit point 8 in the anti-recession groove 7.

[0026] In this embodiment, the connector 1, the fixing seat 6 and the guide tube 2 are all made of alloy plastic, and all three are made by injection molding. The products are mass-produced through molds, and have good size, temperature and consistency.

[0027] When in use, the plastic joint is composed of a connector 1, a guide tube 2, a rubber shockproof ring 3, a rear support ring 4, a metal joint 5 and a fixing seat 6. The rear end of the connector 1 is provided with an external trapezoidal thread 9, and the fixing seat 6 is provided with a matching internal trapezoidal thread.

[0028] During assembly, after the fixing seat 6 is screwed into the connector 1, the limit point 8 on the connector 1 will be stuck in the anti-retraction groove 7 on the fixing seat 6. At this time, the two parts are not easy to loosen. If the two parts need to be separated, the limit point 8 on the connector 1 needs to be moved out of the anti-retraction groove 7 of the fixing seat 6 so that the connector 1 can be screwed out.

[0029] The joint assembly parts are easy to assemble, and the anti-retraction groove 7 structure is added to effectively prevent the product from loosening during circulation, and has a certain error-proofing function. At the same time, it also eliminates the process of using glue to bond due to poor thread fixation, reduces the process, and is also conducive to reducing product production costs.
