Description

Technical Field

[0001] This utility model relates to the field of jack technology, specifically to an anti-slip jack. Background Technology

[0002] A jack is a small, lightweight lifting device that uses a rigid lifting component as its working device to lift heavy objects within a short stroke via a top support or bottom claw. Jacks are mainly used in factories, mines, and transportation sectors for vehicle repair and other lifting and support work. They are lightweight, sturdy, flexible, and reliable, and can be carried and operated by one person. Current jacks typically use a reciprocating lever; the claw pushes the ratchet to rotate, and the small bevel gear drives the large bevel gear, causing the lifting screw to rotate, thus raising or lowering the lifting sleeve to achieve the lifting and pulling function. However, this adjustment method prevents the lifting sleeve from self-locking after lifting, and the lifting sleeve may retract during use, resulting in dangerous situations and low safety.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is an anti-slip jack, comprising:

[0030] The jack structure includes a jack body 12, and a support column 11 is provided inside the jack body 12.

[0031] The jack body 12, as the main structure, can control the lifting and lowering of the support column 11 through the internal transmission structure. The support column 11 is used to contact the heavy object and push the heavy object away under the drive of the jack body 12.

[0032] The reinforcing structure includes a limiting sleeve 21, a locking block 22, a locking groove 221, and a tension spring 23;

[0033] The limiting sleeve 21 is set on the top of the jack body 12, the locking block 22 is embedded in the inside of the limiting sleeve 21, the tension spring 23 is fixedly connected between the limiting sleeve 21 and the locking block 22, the locking groove 221 is opened on the surface of the support column 11, and the side end of the locking block 22 and the surface of the locking groove 221 engage with each other.

[0034] The limiting sleeve 21 is used to limit and fix the card block 22. The card block 22 is used to cooperate with the card groove 221 to position and reinforce the position of the support column 11. The tension spring 23 is used to pull the card block 22 so that the card block 22 and the card groove 221 are stably and firmly engaged.

[0035] Both the side ends of the slot 221 and the block 22 are right-angled triangular structures. When the support column 11 moves upward, the side end surfaces of the slot 221 and the block 22 are tangent.

[0036] The right-angled triangle structure allows the surface groove 221 of the support column 11 to be tangent to the side surface of the block 22 when the support column 11 moves upward, so that the upward movement of the support column 11 will not be obstructed or interfered with. The block 22 lifts the support column 11 by contacting the groove 221 with its end plane, preventing the support column 11 from sliding back and improving the stability of the support.

[0037] It also includes a fixed cylinder 28, a connecting block 29, a spring 27, and a top block 25. The bottom of the locking block 22 is fixedly connected to a transmission block 24. The fixed cylinder 28 is set on the surface of the jack body 12. The connecting block 29 is embedded inside the fixed cylinder 28. The spring 27 is set on the side of the connecting block 29. The top block 25 is fixedly connected to the top of the connecting block 29. The top block 25 has an isosceles triangular structure.

[0038] The transmission block 24 is used to drive the locking block 22 to move. The fixed cylinder 28 is used to install the limiting connecting block 29. The connecting block 29 is used to guide the top block 25 to move. The spring 27 is used to press and position the top block 25. The movement of the top block 25 and its contact with the two transmission blocks 24 can synchronously control the two locking blocks 22 to move outward and separate from the slot 221.

[0039] A control rod 26 is fixedly connected to the surface of the connecting block 29, and a pull ring is fixedly connected to the side end of the control rod 26;

[0040] The control lever 26 facilitates the movement of the connecting block 29. The pull ring at the end of the control lever 26 is connected by a traction rope, which allows the operator to control the movement of the top block 25 remotely.

[0041] Working principle: A control rod 26 is fixedly connected to the surface of the connecting block 29, and a pull ring is fixedly connected to the side end of the control rod 26;

[0042] Under the pulling force of the tension spring 23, the limiting sleeve 21 limits the locking block 22. The locking block 22 lifts the slot 221 horizontally through the right-angled triangular teeth at its end, which can complete the positioning and anti-slip reinforcement of the support column 11. With the bottom surface of the teeth at the end of the locking block 22 tangent to the slot 221, the support column 11 can be freely controlled to move upward and rise. The moving control rod 26 drives the connecting block 29 to move outward. The connecting block 29 drives the top block 25 to move and contact the transmission block 24. The transmission block 24 and the surface of the top block 25 contact and press. The two transmission blocks 24 can respectively drive the locking block 22 at the end to move outward and separate from the slot 221. Then the support column 11 can be controlled to descend and reset. The spring 27 pushes the connecting block 29 to reset, which is convenient for subsequent operation and use.

[0043] This step can fix the support column 11 in place, which is convenient to use and has high anti-slip stability.

[0044] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes auxiliary components;

[0045] The auxiliary components include a base 31, a pulley 32, a second spring 34, a plug block 35, and a lifting frame 36;
