Description

Technical Field

[0001] The utility model relates to the technical field of universal joint forks, in particular to a universal joint fork with a double-side locking structure. Background Art

[0002] The universal joint fork is a fork-shaped structural member that is directly connected to the input shaft or output shaft. The main function of the universal joint fork is to change the direction of force transmission and allow the angular displacement of the connection part to vary within a certain range. They are usually composed of two parts of a cross-shaped structure, which are connected to a cross shaft and supported by bearings. The universal joint fork can be used alone or in pairs to meet different mechanical needs. In the automotive field, the universal joint fork is 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. When testing the universal joint fork, the shafts on both sides need to be locked and then slowly rotated for testing.

[0003] The above-mentioned prior art solutions have the following defects: the existing detection equipment cannot be adaptively adjusted for universal joint forks of different sizes, and its use is limited. Utility Model Content

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

[0006] A universal joint fork with a double-sided locking structure comprises a universal joint fork body, a support seat is arranged on the outer side of the universal joint fork body, a cavity is opened inside the support seat, a sliding rod is arranged inside the cavity, a fixing block is fixedly connected to the outer side of the support seat, a groove is opened inside the fixing block, a connecting rod and a spring are arranged inside the groove, and a splint is fixedly connected to the outer side of the connecting rod.

[0007] By adopting the above technical solution, a structure that can be adapted to the outside of the universal joint fork is added, and the device can be adjusted according to the diameter of the upper end of different universal joint forks. The two sets of support seats can be stretched outward to make the support seats and the outside of the universal joint fork contact each other, and then the splint and the structure on the outside of the universal joint fork are engaged through the expansion and contraction action of the spring, so that the device can be installed and fixed, and it can be adapted to most universal joint forks.

[0008] Furthermore, the sliding rod, fixed block, groove, connecting rod, spring and clamp are symmetrically arranged in two groups, each group of connecting rods and springs is provided with two, the connecting rod and the fixed block are movably connected by the spring, and the outer side of the clamp adopts an arc structure.

[0009] By adopting the above technical solution and the symmetrical structure design, the device can be snap-fitted and installed with the universal joint fork from both sides at the same time, thereby improving the stability of the structure. At the same time, the arc structure on the outer side of the splint can make the outer end better contact with the outer side of the universal joint fork, thereby facilitating snap-fitting.

[0010] Furthermore, two support seats are symmetrically arranged, the outer side of one support seat is fixedly connected to a first connection block, and the outer side of the other support seat is fixedly connected to a second connection block.

[0011] By adopting the above technical solution and adding two sets of connecting blocks, the structure in contact with one end of the universal cross shaft can be installed, which is convenient for use.

[0012] Furthermore, the first connecting block and the second connecting block are both internally inserted with the same screw rod, one end of the outer side of the screw rod is rotatably connected to a locking plate via a bearing, and a nut is arranged on the outer side of the screw rod.

[0013] By adopting the above technical solution, by adding screws and nuts, the locking plate can be raised and lowered by the screws to facilitate locking on both sides. At the same time, after the locking on both sides is completed, the nuts can be locked to limit the position to prevent the screw from moving.

[0014] Furthermore, the first connection block and the second connection block are of the same size and the same specification, the screw is threadedly connected to the first connection block and the second connection block respectively, and the nut is threadedly connected to the screw.

[0015] By adopting the above technical solution and adding two sets of screw rods, a double-sided locking structure can be achieved.

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

[0017] A support seat, spring, splint and locking plate are used, and the screw and locking plate structure are installed on the connecting block, which is convenient for operation and use. At the same time, the whole device can be adaptively adjusted according to the universal joint forks of different diameters. The support seats on both sides can be pulled by the sliding rod, and then the support seats are engaged to the outside of the universal joint fork. At the same time, the splint and the universal joint fork are engaged through the expansion and contraction action of the spring to achieve quick fixation. Thereafter, the screw is manually rotated to drive the locking plate to rise and fall to achieve double-sided locking. At the same time, the screw is locked with a nut to achieve limited fixation, which produces an effect of convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
