Technical Field

[0001] The utility model relates to the technical field of cylindrical hydraulic jack construction, in particular to a self-locking sleeve device suitable for cylindrical hydraulic jacks. Background Art

[0002] At present, cylindrical jacks have been widely used in various production fields such as engineering construction, mechanical processing, and automobile maintenance due to their small size, light weight, and strong flexibility. However, cylindrical jacks are often deformed, unstable, tipped over, damaged, or broken during use due to improper operation, the weight of the heavy objects exceeding the maximum lifting force, and weak lower bearing surface. Especially if the jack tips over during the lifting of heavy objects, it will largely lead to safety accidents and cause loss of life and property. Summary of the invention

[0003] In view of the above-mentioned prior art, the utility model proposes a self-locking sleeve device suitable for a cylindrical hydraulic jack.

[0004] The utility model provides a self-locking sleeve device suitable for a cylindrical hydraulic jack, comprising a sleeve body, a circular ring is arranged on the inner bottom of the sleeve body, a plurality of L-shaped positioning seats are distributed on the circular ring, a sleeve is arranged on the circular ring between adjacent L-shaped positioning seats, and a notch is arranged on the side wall of the sleeve body.

[0005] Preferably, the sleeve body is a steel sleeve, and the diameter of the sleeve body is 10 mm larger than the diameter of the cylindrical hydraulic jack.

[0006] Preferably, the circular ring is a solid steel ring.

[0007] Preferably, the casing is a hollow steel pipe.

[0008] Preferably, the L-shaped positioning seat is made of equilateral angle steel, and the ring passes through the root of the equilateral angle steel.

[0009] Preferably, the L-shaped positioning seats are provided in three numbers and are evenly distributed at 120°.

[0010] Preferably, a rubber pad is provided on the inner side of the top of the L-shaped positioning seat.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a self-locking sleeve device suitable for a cylindrical hydraulic jack, a rotatable L-shaped positioning seat is arranged at the bottom of the sleeve, when the jack is pressed on one side of the L-shaped positioning seat, the other side of the L-shaped positioning seat will be stuck on the side wall of the jack, forming a self-locking effect, and improving the safety and reliability of the cylindrical jack. The device of the utility model can be reused, and is simple to process and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The present invention is a schematic structural diagram of a self-locking sleeve device suitable for a cylindrical hydraulic jack in an embodiment of the present invention.

[0013] In the figure: 1. sleeve body; 2. ring; 3. L-shaped positioning seat; 4. rubber pad; 5. sleeve; 6. notch. DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0015] Example: Figure 1 A self-locking sleeve device suitable for a cylindrical hydraulic jack is shown, comprising a sleeve body 1, the sleeve body 1 is made of a steel sleeve, and its diameter is 10 mm larger than the diameter of the cylindrical hydraulic jack, a circular ring 2 is arranged at the inner bottom of the sleeve body 1, the circular ring 2 is made of a solid steel ring with a diameter of 5 mm, three rotatable L-shaped locating seats 3 are arranged on the circular ring 2, the three L-shaped locating seats 3 are evenly distributed at 120°, the L-shaped locating seats 3 are made of equilateral angle steel, the circular ring 2 passes through the root of the equilateral angle steel, a rubber pad 4 is arranged on the inner side of the top of the L-shaped locating seat 3, a sleeve 5 is arranged on the circular ring 2 between adjacent L-shaped locating seats 3, the sleeve 5 is made of a hollow steel pipe with a diameter of 7 mm, and a through-length slot 6 is arranged on the side wall of the sleeve body 1 to ensure that the hydraulic oil pipe of the cylindrical hydraulic jack is exposed.

[0016] When the self-locking sleeve device is used in a specific application, a cylindrical hydraulic jack is placed in the sleeve body 1, and the oil pipe part is aligned with the notch 6, so that the bottom of the cylindrical hydraulic jack is pressed on one side of the L-shaped positioning seat 3, and the other side of the L-shaped positioning seat 3 will automatically be stuck on the side wall of the jack to form a self-locking effect, ensuring that the jack body is stable and reliable when working.

[0017] The device can ensure that the cylindrical jack always remains stable during use, fundamentally solves the problem of tipping over, and improves the safety and reliability of the cylindrical jack.

[0018] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model.
