Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The invention is specifically implemented as shown in fig. 1 and fig. 2, and comprises a push rod 1 and a push rod buckle 2, wherein the head of the push rod 1 is provided with a round hole a which is not completely penetrated, the push rod 1 is provided with two steps, and the push rod comprises bulges which are uniformly distributed on the inner wall of the round hole a along the circumference and are used as a first step b and an outer hole end face of the round hole a which is used as a second step c as shown in fig. 3.

As shown in fig. 4, the push rod buckle 2 is a cylindrical tube structure, a ball pit d is formed on the end surface of the inner end portion, the end portion of the pedal ball pin 3 is a spherical structure, and the ball pit d of the push rod buckle 2 is connected with the end portion of the pedal ball pin 3 through a ball hinge.

As shown in fig. 4, three grooves are uniformly distributed on the side wall of the inner end of the push rod buckle 2, a plurality of axially extending reverse bending reverse buckling inverted clamping jaws e are uniformly distributed along the circumference at intervals on the outer end, and the inverted clamping jaws e are fixedly connected with a first gear step b or a second gear step c on a round hole a of the push rod 1, so that the quick connection between the push rod assembly of the clutch master cylinder and the pedal is realized.

As shown in fig. 5-7, two steps are arranged on the head circular hole a of the push rod 1, the first step b is used for initial installation and limitation of the push rod buckle 2, and the second step c is used for limiting and anti-falling after the push rod buckle 2 is installed in place. First shelves step b is detained into earlier to back-off type jack catch e, then after 2 tip impressing push rod buckles 2 ball holes d of push rod buckle 2, further extrudees push rod buckle 2 and moves forward and make back-off type jack catch e joint to second shelves step c department and accomplish the installation.

In specific implementation, the push rod 1 and the push rod buckle 2 need to be made of high-molecular polymers through injection molding. The high molecular polymer has higher strength and good injection molding performance, and meets the use conditions of the push rod assembly of the clutch master cylinder.

The working process of the utility model is as follows:

fig. 1 is a schematic view of the push rod assembly, where the push rod buckle 2 is at an initial position and the inverted claw e is at the first step (b) of the push rod.

Fig. 5 to 7 are schematic views of the installation process:

as shown in fig. 5, step one: aligning the ball pin 3 with the opening part of the ball pit d of the push rod buckle 2, fitting, enabling the push rod buckle 2 to be at an initial installation position, and enabling the inverted clamping jaw e to be at the first step (b) of the push rod.

As shown in fig. 6, step two: the push rod 1 is pushed towards the ball pin 3, so that the ball pin 3 slides into the ball socket d of the push rod buckle 2, meanwhile, the push rod buckle 2 is still at the initial installation position, and the inverted claw e is arranged at the first step (b) of the push rod.

As shown in fig. 7, in the third step, the push rod 1 is pushed continuously, so that the ball pin 3 and the push rod buckle 2 are pressed into the round hole a of the push rod 1 together, and at this time, the inverted claw e on the push rod buckle 2 is at the second step (c) of the push rod 1, thereby completing the connection assembly.

During the dismantlement, only need to warp back-off type jack catch e, throw off second shelves step (c), can withdraw from round hole an with ball round pin 3 and push rod buckle 2 together, make back-off type jack catch get back to on first shelves step (b), break away from ball round pin 3 again, accomplish the dismantlement.
