Description

Technical Field

[0001] The utility model belongs to the technical field of jacks, and in particular relates to a multi-purpose tray adjustment structure. Background Art

[0002] The horizontal jack is one of the more common car jacks available. Its working principle is: by pressing the handle, the hydraulic pump transmits force to rotate the lifting arm, so that the bracket and the tray on the bracket located at the far end of the rotating arm rise, thereby supporting the car to rise. In the existing jack structure, in order to adjust the height of the tray, a high-position rod is added between the bracket and the tray, but the high-position rod is easy to lose, and the height adjustment is single when used; or multiple high-position rods of different lengths are required to meet the required height, so the adjustment method is cumbersome. In addition, the trays on the added high-position rod cannot rotate. For this reason, the jack sometimes fails to meet the corresponding test standard requirements, resulting in poor test results.

[0003] In view of the above-mentioned prior art, it is necessary to reasonably improve the tray structure of the existing jack. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Utility Model Content

[0025] See also Figure 1 The utility model relates to a multi-purpose pallet adjustment structure. The pallet is installed on a horizontal jack, namely the pallet component 6 in the figure. The horizontal jack includes a front wheel 1, a wall panel component 2, a rear wheel 3, a lifting arm 4, a bracket component 5, a pallet component 6, and a handle 7. The wall panel component 2 is provided with mounting ends of the front wheel 1, the rear wheel 3, the lifting arm 4, and the handle 7. The bracket component 5 is arranged on the extended end of the lifting arm 4. The pallet component 6 is provided with a pallet adjustment hole 622, and the bracket component 5 is provided with a pallet fixing hole 55. The pallet component 6 is inserted into the bracket component 5 from top to bottom and a fixed shaft 8 is used to pass through the connected pallet adjustment hole 622 and the pallet fixing hole 55 to achieve the fixing of the bracket component 5 and the pallet component 6. Stoppers 9 are provided at both ends of the fixed shaft 8 to prevent the fixed shaft 8 from slipping.

[0026] like Figure 2 As shown, the tray component 6 includes a tray screw 61, an adjustment rod 62, and a tray 63 located above the adjustment rod 62. The tray screw 61 passes through the tray 63 and is screwed into the threaded hole 621 of the adjustment rod 62, and the tray 63 is fixed to the adjustment rod 62 by threaded connection; or, the tray screw 61 passes through the tray 63 and is welded to the adjustment rod 62. The tray 63 can be flexibly rotated between the tray screw 61 and the adjustment rod 62. The tray adjustment hole 622 is through-opened on the adjustment rod 62. Further, the tray adjustment hole 622 is provided with one or more. Further, the tray adjustment hole 622 is through-opened at different heights of the adjustment rod 62. A tray pad 631 can be configured on the tray 63.

[0027] like Figure 3a , 3b As shown, the bracket component 5 includes an adjustment sleeve 51, a reinforcement plate 52, a bracket 53 and a connecting rod pin 54. The adjustment sleeve 51 is welded to the upper surface of the bracket 53. Specifically, the adjustment sleeve 51 is welded to the lower part of the upper surface of the bracket 53, and a reinforcement plate 52 is added at the welding point between the adjustment sleeve 51 and the bracket 53. The tray fixing hole 55 is through-opened on the adjustment sleeve 51 and the bracket 53. The connecting rod pin 54 is used to assemble the bracket 53 to the boom 4.

[0028] Please continue reading Figures 1 to 3b The working process of the multi-purpose pallet adjustment structure described in the utility model is as follows: the adjustment rod 62 is inserted into the adjustment sleeve 51. When the pallet adjustment hole 622 of a certain height is connected to the pallet fixing hole 55, the fixing shaft 8 is passed through the connected pallet adjustment hole 622 and pallet fixing hole 55 to fix the bracket component 5 and the pallet component 6. Then, blocking members 9 are provided at both ends of the fixing shaft 8 to prevent the fixing shaft 8 from slipping. Therefore, when lifting different vehicles, the adjustment of different heights can be completed by adjusting the pallet component 5 to the corresponding height and locking it. The structure is simple and easy to debug.

[0029] The blocking member 9 may be a retaining ring. Furthermore, the retaining rings at both ends of the fixed shaft 8 are connected by a connecting member to form an annular retaining ring 91.

[0030] like Figure 4 , Figure 5 As shown, when the jack is not in use, the handle 7 can be rotated 180 degrees and placed above the tray 63, and an annular retaining ring 91 is used to bypass the two ends of the handle 7 and fix them on the fixed shaft 8, so that the handle 7 is fixed above the tray 63. At this time, the handle 7 can be used as a handle to facilitate lifting and carrying the jack, and the fixed shaft 8 is used to fix the tray component 6 and the bracket component 5, and can also be used to fix the handle 7.
