Technical Field

[0001] The utility model relates to the technical field of jacks, in particular to a jack with a safety support structure. Background Art

[0002] A jack is a lightweight lifting device that uses a rigid lifting member as a working mechanism to lift heavy objects within a short stroke of a top support or bottom claw. Jacks are primarily used in factories, mines, transportation, and other sectors for vehicle repair and other lifting and supporting tasks. Their lightweight, sturdy structure is flexible and reliable, and can be carried and operated by one person.

[0003] Existing jacks generally do not have a safety support structure, which makes them prone to tilting and sliding during use. In addition, the safety support structure is fixed on the jack. If the safety support structure cannot be removed during damage and repair, it can only be scrapped together with the jack, which is a waste of resources. Therefore, a jack with a safety support structure is needed. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1:

[0024] like Figure 1-4 As shown, this embodiment provides a jack with a safety support structure, including a jack body 1, a top body 2 installed in the jack body 1, a base 3 installed at the bottom of the jack body 1, a safety release valve 4 installed on the base 3, a piston 5 installed on the base 3, and a handle bracket 6 installed on the piston 5;

[0025] When the locking cam 75 is unlocked, the locking cam 77 is unlocked and the locking cam 78 is unlocked, so that the stair jack 70 can be unlocked, and the stair jack 70 can be unlocked when the stair jack 70 is unlocked.

[0026] Further, refer to Figure 3 A screw rod 77 is rotatably installed in the support box 71 , and a contact block 78 is installed on the screw rod 77 . The setting of the screw rod 77 and the contact block 78 can fix the jack body 1 in the support box 71 .

[0027] Further, refer to Figure 3A connecting plate 79 is installed on the support box 71, and a rubber pad 710 is installed on the connecting plate 79. The arrangement of the connecting plate 79 and the rubber pad 710 can make the support box 71 more firmly fixed.

[0028] Further, refer to Figure 3 A connecting block 74 is installed on the fixing rod 73, and a pulling block 711 is installed on the connecting block 74. The setting of the pulling block 711 can make it easier to pull the fixing rod 73.

[0029] Example 2:

[0030] like Figure 1 、 Figure 4 As shown, based on the embodiment 1, the jack body 1 can be prevented from moving and tilting by setting a safety support assembly.

[0031] The safety support assembly includes a support block 81, which is mounted at the bottom of the support box 71, a support rod 82 is mounted in the support block 81, a rotating rod 83 is rotatably mounted on the support rod 82, a shift block 84 is provided on the base 3, the rotating rod 83 is rotatably mounted in the shift block 84, a support bar 85 is mounted on the base 3, a shock-absorbing spring 86 is mounted on the support bar 85, and the other end of the shock-absorbing spring 86 is mounted on the shift block 84, a connecting frame 87 is mounted on the support box 71, and a support plate 88 is mounted at the bottom of the connecting frame 87. The support plate 88 is placed on the ground, and the support box 71 is fixed on the jack body 1. The jack body 1 will be supported by the support box 71 when it tilts. When the support box 71 moves up and down, it will drive the support block 81 to move. The movement of the support block 81 drives the shock-absorbing spring 86 to be compressed. The compression of the shock-absorbing spring 86 can share the force generated by the support box 71. The setting of the damper 810 can prevent the support box 71 from shaking. This setting can prevent the jack body 1 from moving and tilting, and play a role of safety support.

[0032] Further, refer to Figure 4 A limit block 89 is installed on the support rod 82, and the limit block 89 is installed on the outside of the support block 81. The setting of the limit block 89 can prevent the support rod 82 from moving out of the support block 81.

[0033] Further, refer to Figure 4 A damper 810 is installed on the base 3, and the other end of the damper 810 is installed at the bottom of the support box 71. The setting of the damper 810 can provide resistance to movement and consume movement energy.

[0034] Further, refer to Figure 4 A slide groove 811 is provided on the base 3, and a slider 812 is installed at the bottom of the moving block 84. The slider 812 is slidably installed in the slide groove 811. The setting of the slide groove 811 and the slider 812 can limit the position of the moving block 84 so that the moving block 84 can only move on the base 3.

[0035] The working principle of the present invention is as follows: when in use, pull the pulling block 711, the pulling block 711 drives the connecting block 74 to move, the connecting block 74 moves and drives the fixing rod 73 to move, the fixing rod 73 moves and drives the fixing block 76 to move, and then the jack body 1 is placed in the support box 71, and the pulling block 711 is released. Due to the setting of the spring 75, the fixing block 76 will return to its original position and move into the fixing ring 72, and then the screw rod 77 is rotated. The screw 77 rotates and drives the contact block 78 to contact the jack body 1, fixing the jack body 1 in the support box 71. In this way, the safety support structure can be disassembled and assembled to prevent the safety support structure from being damaged and unable to be disassembled, and being scrapped together with the jack body 1. , waste resources, place the support plate 88 on the ground, and the support box 71 is fixed on the jack body 1. The jack body 1 will be supported by the support box 71 when it tilts. When the support box 71 moves up and down, it will drive the support block 81 to move, and the support block 81 moves to drive the support rod 82 to move, and the support rod 82 moves to drive the rotating rod 83 to rotate, and the rotating rod 83 rotates to drive the moving block 84 to move, and the moving block 84 moves to drive the shock-absorbing spring 86 to be compressed. The compression of the shock-absorbing spring 86 can share the force generated by the support box 71, and the setting of the damper 810 can prevent the support box 71 from shaking. This setting can prevent the jack body 1 from moving and tilting, and play a role of safety support.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
