Technical Field

[0001] This utility model relates to the field of mechanical installation technology, specifically a quick installation device for retaining rings. Background Technology

[0002] The drive axle is an important component of the automotive transmission system, located at the end of the transmission system. Its main function is to transmit the power from the drive shaft to the drive wheels through the final drive, differential, half shafts, etc., to achieve speed reduction and torque increase, change the direction of power transmission, and allow the left and right wheels to rotate at different speeds, so as to ensure the normal driving of the vehicle under various driving conditions.

[0003] A retaining ring needs to be installed in the drive axle housing, but the retaining ring mounting slot is blocked by the brake pads. The existing method of installing the retaining ring is to use a screwdriver to pry the retaining ring into the retaining ring mounting slot in the housing. This installation method carries the risk of the screwdriver scratching the parts and also poses a safety hazard of the retaining ring suddenly popping out during installation. Utility Model Content

[0006] Based on the above scheme and as a preferred embodiment: the quick-release pin includes a pin body, which is tubular, and a through hole is provided at one end of the pin body near the proximal end, in which a steel ball is movably disposed; a pin core is provided inside the pin body; a beveled groove corresponding to the steel ball is provided at the proximal end of the pin core near the through hole, and a first limiting protrusion is provided at the proximal end of the other end; a limiting spring is sleeved on the pin core near the first limiting protrusion, with one end of the limiting spring abutting against the pin body and the other end abutting against the first limiting protrusion.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a limiting device is provided at one end of the pin body near the spring, the limiting device including a limiting sleeve and a second limiting protrusion ring; the limiting sleeve is externally threaded to the pin body, and the second limiting protrusion ring abuts against the side of the first limiting protrusion ring away from the limiting spring.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting device further includes a gripping protrusion ring.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the rotating handle is shaped like a star.

[0010] The beneficial effects of this utility model are as follows: Based on the quick installation device for retaining rings of this utility model, the main body of the device is fixed to the housing by using a quick-release pin, which makes the operation quick and convenient. Rotating the handle causes the screw to push the brake pad inside the housing, exposing the retaining ring mounting groove of the housing, and installing the retaining ring into the retaining ring mounting groove. This avoids damage to the parts caused by using a screwdriver to pry, and avoids the safety hazard of the retaining ring suddenly popping out. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Combination Figure 1-4 This embodiment provides a detailed description of a quick-installation device for a retaining ring, comprising: a device body 1, a quick-release pin 2, and a rotating screw 3; the device body 1 has a light hole 4, and the end of the quick-release pin 2 is inserted into a hole on a housing 5 through the light hole 4, thereby fixing the device body 1 to the housing 5; the rotating screw 3 includes a rotating handle 6 and a screw 7, the rotating handle 6 and the screw 7 are fitted together, and the screw 7 is threadedly connected to the device body 1.

[0018] Furthermore, the quick-release pin 2 includes a pin body 8, which is tubular. A through hole is provided at one end of the pin body 8, and a steel ball 9 is movably disposed in the through hole. A pin core 10 is provided inside the pin body 8. A beveled groove 11 corresponding to the steel ball 9 is provided at the proximal end of the pin core 10 near the through hole, and a first limiting protrusion ring 12 is provided at the proximal end of the other end. A limiting spring 13 is sleeved on the pin core 10 near the first limiting protrusion ring 12. One end of the limiting spring 13 abuts against the pin body 8, and the other end abuts against the first limiting protrusion ring 12.

[0019] When the pin 10 is pressed down so that the steel ball 9 is in the inclined groove 11, the outer end face of the steel ball 9 is just hidden in the through hole of the pin body 8. Insert the pin body 8 into the hole on the housing 5 through the light hole 4, release the pin 10, and the limit spring 13 returns to the released state. The inner end face of the steel ball 9 is pressed against the outer wall of the pin 10, and the outer end face of the steel ball 9 protrudes from the through hole to the outside of the pin body 8 and abuts against the hole on the housing 5, so that the main body 1 of the device is fixed to the housing 5. Rotate the rotating handle 6 so that the screw 7 pushes the brake pad 17 inside the housing 5, exposing the retaining ring mounting groove 18, and install the retaining ring 19 in the retaining ring mounting groove 18.

[0020] Furthermore, a limiting device is provided at one end of the pin 8 near the spring. The limiting device includes a limiting sleeve 14 and a second limiting protrusion ring 15. The limiting sleeve 14 is externally threaded to the pin 8, and the second limiting protrusion ring 15 abuts against the side of the first limiting protrusion ring 12 away from the limiting spring 13.

[0021] Furthermore, the limiting device also includes a gripping protrusion 16. The gripping protrusion 16 facilitates pressing the pin 13.

[0022] Furthermore, the rotary handle 6 is shaped like a star (or a cross). This star-shaped design increases friction, preventing slippage and making it easier for the operator to use.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
