Description

Technical Field

[0001] This utility model relates to the field of virtual reality glasses technology, and in particular to a horizontal jack traction device. Background Technology

[0002] A horizontal jack is a lightweight lifting device with a rigid lifting component as its working device. It lifts heavy objects within a short stroke through a top support. It is mainly used on heavy-duty vehicles or mobile equipment to support the weight of the equipment and adjust its level. Horizontal jacks are widely used in factories, mines, transportation and other sectors for vehicle repair and other lifting and support work. Horizontal jacks are usually equipped with traction components to facilitate alignment and movement of the entire unit.

[0003] Existing horizontal jack traction components have the following drawbacks: When moving existing horizontal jacks, they are generally tractioned by moving wheels on both sides of the bottom, with the jack body located on top of the moving wheels. When using horizontal jacks for lifting, especially for some unstable heavy objects, the jack may shift and sway during the lifting process due to the reliance on the wheel structure for support, affecting operational safety. Therefore, we propose a horizontal jack traction device. Utility Model Content

[0004] The main purpose of this utility model is to provide a horizontal jack traction device. By setting traction mechanisms on both sides of the horizontal jack and using adjustable traction components, it can be tractioned normally when moving and lifted off the ground when being lifted, thereby improving the stability of the jack during operation and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A horizontal jack traction device includes a horizontal jack and a traction mechanism. The traction mechanism is provided on the side of the horizontal jack. The traction mechanism includes a fixed plate, a spring, a mounting plate, a moving wheel, a vertical plate, a sleeve, an arc-shaped protrusion, a limiting groove, an arc-shaped top block, a hollow tube, a movable rod, and an insert rod. Fixed plates are welded to both sides of the horizontal jack, and the bottom of each fixed plate is movably connected to a mounting plate via a spring. Moving wheels are installed on the bottom of each mounting plate via screws. Vertical plates are symmetrically welded to the bottom of the fixed plates on the same side of the horizontal jack. A sleeve is movably connected between the vertical plates via bearings. An arc-shaped protrusion is welded to the top of the mounting plate at the top position of the sleeve, and a limiting groove is formed at the top of the arc-shaped protrusion. Arc-shaped top blocks are welded to the bottom of the sleeve at positions corresponding to the arc-shaped protrusion. A hollow tube is welded to the inner wall of the sleeve, and a movable rod is inserted between the hollow tubes. A vertical rod is welded to the bottom of the movable rod near the arc-shaped top block, and the bottom end of the vertical rod corresponds to the position of the limiting groove.

[0007] Furthermore, it also includes a traction mechanism. The operating end of the horizontal jack is equipped with a traction mechanism, which includes an adjusting rod, a control rod, side clamps, a rotating shaft, and a handle. The operating end of the horizontal jack is equipped with an adjusting rod, and a control rod is inserted into the end of the adjusting rod. Side clamps are symmetrically welded to the outer wall of the control rod away from the end of the adjusting rod. A rotating shaft is installed inside each side clamp and a handle is movably connected to it through the rotating shaft. The top of the horizontal jack is equipped with an adjusting rod, and the lifting height of the horizontal jack can be adjusted by repeatedly pressing the adjusting rod. When the lever is turned, the jack can be lowered. A control lever is inserted into the end of the adjusting rod to extend the operating distance. The end of the control lever is equipped with a side clamp and a handle. The handle can rotate around the pivot. Under normal use, the handle and the control lever are in a straight line, which facilitates the operation of the horizontal jack. When movement is required, the screw can be turned to disconnect the connection between the handle and the end of the control lever. At the same time, the handle can be rotated so that it is perpendicular to the end of the control lever. At this time, the handle is positioned horizontally at the end of the control lever, which makes it easier to push and pull the horizontal jack.

[0008] Furthermore, the fixed plate has limit holes at both ends of the spring, and the top of the mounting plate is welded with a limit rod that passes through the limit hole; the top of the limit rod passes through the limit hole, and the two work together to ensure that the mounting plate and the moving wheel will not shift or wobble.

[0009] Furthermore, a through groove is provided at the bottom of the sleeve and the middle position inside the arc-shaped top block, and the through groove corresponds to the position of the limiting groove; when the movable rod is pulled, the insertion rod is driven to move along the through groove, and at the same time, it is convenient to insert it into the limiting groove.

[0010] Furthermore, an end ring is welded to the end of the movable rod away from the sleeve, and a rubber plug corresponding to the inner diameter of the sleeve is bonded to the surface of the end ring facing the movable rod. When the movable rod and the insert rod are used for limiting, the movable rod is moved so that the bottom insert rod is inserted into the limiting groove. After insertion, the rear end ring fits perfectly against the end of the sleeve, and at the same time, the rubber plug is inserted into the inner wall of the sleeve. The friction between the rubber plug and the inner wall of the sleeve is used to fix the position of the movable rod so that it will not slide at will.

[0011] Furthermore, the grip has a screw hole A inside and a screw rod is screwed into the screw hole A. The control lever has a screw hole B at one end facing the grip and the end of the screw rod is screwed into the screw hole B. The position of the end of the screw rod can be adjusted by turning the screw rod along the screw hole A. When the end is screwed into the screw hole B, the position of the grip rod is fixed. When the end is screwed out of the screw hole B, the angle of the grip rod can be adjusted.

[0012] Compared with the prior art, this utility model has the following advantages: A traction mechanism is provided on both sides of the horizontal jack. The bottom of the fixed plate is connected to the mounting plate and the moving wheel via a spring. In the normal non-use state, the arc-shaped top block at the bottom of the fixed plate is aligned with the end of the arc-shaped protrusion at the top of the mounting plate. At this time, the insertion rod is inserted between the through groove and the limiting groove, and the fixed sleeve prevents it from rotating. In this state, the mounting plate is pushed downwards, the bottom of the moving wheel contacts the ground, and the entire horizontal jack is lifted off the ground. At this time, the horizontal jack can be easily pulled and moved to adjust its position. When the horizontal jack is moved to the use position, the movable rod is pulled horizontally to move the insertion rod out of the limiting groove. Then, the sleeve is screwed to cause the arc-shaped top block and the arc-shaped protrusion to misalign. After losing support, the mounting plate and the moving wheel are driven back to their original position by the spring, raising the height of the mounting plate and the moving wheel off the ground and simultaneously retracting them to the sides of the horizontal jack. At this time, the bottom of the horizontal jack is in direct contact with the ground, which is significantly better than existing technologies. The jack's wheel support structure provides a larger contact area with the ground, improving stability during lifting and preventing wobbling. After use, to move the jack, simply tighten the sleeve to lift the entire horizontal jack and secure it with the insertion rod. This flexible adjustment allows for better stability and ease of movement during different applications. The top of the horizontal jack features an adjustment rod; pressing the rod repeatedly adjusts the lifting height, while tightening it controls the descent of the lifting end. A control rod extends the operating distance by connecting to the end of the adjustment rod. The control rod has a side clamp and a handle that rotates around the pivot. Under normal use, the handle and control rod are aligned for easy operation. To move the jack, tighten the screw to disconnect the handle from the control rod and rotate the handle to align it perpendicular to the control rod. The handle then lies laterally at the end of the control rod, facilitating pushing and pulling. Attached Figure Description

The handle 305 can rotate around the rotating shaft 304. Under normal use, the handle 305 and the control rod 302 are in a straight line, which facilitates the operation of the horizontal jack 1. When it is necessary to move, the screw 308 can be turned to disconnect the connection between the handle 305 and the end of the control rod 302. At the same time, the handle 305 is rotated so that it is perpendicular to the end of the control rod 302. At this time, the handle 305 is horizontally positioned at the end of the control rod 302, which makes it easier to push and pull the horizontal jack 1.

[0023] The fixed plate 201 has limit holes 205 at both ends of the spring 202. The top of the mounting plate 203 is welded with a limit rod 206 that passes through the limit hole 205. The bottom of the sleeve 208 and the middle of the arc-shaped top block 211 are provided with through grooves 212, which correspond to the positions of the limit grooves 210.
