Description

Technical Field

[0001] The utility model relates to the technical field of universal joint forks, in particular to a universal joint fork which is flexible in use and durable. Background Art

[0002] Universal joints are fork-shaped structural parts that are directly connected to the input shaft or output shaft. The main function of universal joints is to change the direction of force transmission and allow the angular displacement of the connection part to vary within a certain range. They usually consist of two parts of a cross-shaped structure, which are connected to a cross shaft and supported by bearings. Universal joints can be used alone or in pairs to adapt to different mechanical needs. In the automotive field, universal joints are particularly important because they help ensure that the vehicle's power transmission system can adapt to the up and down jumps during driving, thereby maintaining driving stability and smoothness.

[0003] The above-mentioned prior art solutions have the following defects: the existing universal joint fork structure is fixed and cannot be quickly installed and disassembled with the universal cross shaft, which is inconvenient to operate. Utility Model Content

[0007] By adopting the above technical solution, a movable structure is added to the ear hole position of the universal joint fork, the arc block can be rotated, and it can be locked and fixed by screws. When the universal joint fork and the universal cross shaft are installed, the arc block can be directly opened and one end of the cross shaft can be installed, which is convenient and quick.

[0009] By adopting the above technical solution, the structure of the lower end of the universal joint fork is designed to be telescopically adjustable, and can be adaptively adjusted according to different usage conditions. At the same time, it can be plugged in through the round hole and then limited by the square hole to prevent the structure from rotating during normal use, and then locked by a nut.

[0010] Furthermore, the clamping block and the clamping slot are clamped and connected, the screw passes through the through hole and extends to the inside of the threaded hole, and the screw and the threaded hole are threadedly connected.

[0011] By adopting the above technical solution, the clamping block at one end of the arc block is engaged with the clamping slot, and then the structure is locked and fixed by screws to achieve installation.

[0012] Furthermore, the sleeve is provided with identical round holes and square holes inside, and the round holes and square holes are arranged in multiple groups at equal intervals, and each group of square holes has two symmetrically distributed along the outer side of the round hole, and the round holes and square holes are connected to each other.

[0013] By adopting the above technical solution and designing multiple groups of structures, different positions can be selected for plug-in installation and flexible adjustment for use.

[0014] Furthermore, the cylindrical member and the round hole are matched with each other, the square block is inserted into the inside of the square hole and matched with the square hole, and the external thread and the nut are threadedly connected.

[0015] By adopting the above technical solution, through the cooperation of the square hole and the round hole, the cylindrical part can be more stable after being inserted, preventing the fixing part and the sleeve from being rotationally limited, and finally locking and fixing it with a nut to achieve quick adjustment and installation.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] 1. The arc block and screws are used to design the position of the ear hole end of the universal joint into a structure that can be opened and closed. When installing the cross shaft, the screws can be loosened, and then the arc block can be opened and the cross shaft can be installed, which is convenient for the installation of the entire universal joint and produces a convenient installation effect;

[0018] 2. The fixing parts and sleeves are used to design the original one-piece structure into two retractable structures. The sleeve can be pulled to slide inside the fixing parts to adjust the appropriate length. At the same time, the coordination of the round holes and square holes, as well as the insertion of the square blocks and cylindrical parts, can realize the installation and fixation of the overall structure to prevent rotation during use. It can be adjusted and used at any time, which is more durable and produces a stable working effect. BRIEF DESCRIPTION OF THE DRAWINGS
