Description

Technical Field

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

[0002] Ultra-thin jacks are detachable hydraulic jacks, smaller in size yet capable of generating greater working capacity, suitable for use in confined spaces. The main ultra-thin jack series is the RSM series, offering a particularly complete range of tonnage options. They are characterized by their light weight, large tonnage, and flexible mobility. Mounting holes facilitate easy fixing, and the painted surface enhances corrosion resistance.

[0003] Due to the characteristics of ultra-thin jacks in the existing technology, the lifting end of the ultra-thin jack is relatively small. As a result, when the ultra-thin jack is used for lifting, the lifting part may be dented, which may cause damage to the object being lifted and instability during lifting.

[0004] A search revealed a Chinese patent document disclosing an ultra-high pressure, ultra-thin hydraulic jack (publication number: CN221543987U). This utility model provides an ultra-high pressure, ultra-thin hydraulic jack, relating to the field of hydraulic jacks. It includes a housing, with a limiting groove on the top of the housing. Inside the limiting groove is a first top ring, inside the first top ring is a second top ring, inside the second top ring is a third top ring, and inside the third top ring is a top block. Multiple first grooves are formed on the top surface of the top block, the top surfaces of the first top ring, the second top ring, and the top surface of the third top ring. This utility model increases the overall height of the device by setting the first, second, third top rings, and top block. By controlling the sequential raising of the first, second, third top rings, and top block, the lifting height when lifting an object can be the sum of the first, second, third, and top rings and the top block, thus increasing the height the device can lift an object and allowing for a thinner design. However, it still has the following drawbacks:

[0005] While the aforementioned ultra-thin hydraulic jacks increase the height the device can lift and allow for a thinner design, their inherent characteristics also present a drawback. The lifting end of the ultra-thin jack is relatively small. This can lead to dents in the lifting section during lifting, potentially damaging the object being lifted and causing instability during the lifting process. Utility Model Content

[0006] The purpose of this utility model is to provide an ultra-thin jack, which solves the problem in the background art where the lifting end of the ultra-thin jack is small due to its characteristics. This can cause the lifting part to dent during the lifting process, resulting in damage to the lifted object and instability during lifting.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An ultra-thin jack includes an ultra-thin jack body, a base installed at the bottom end of the ultra-thin jack body, and a lifting end provided inside the top end of the ultra-thin jack body. A main support block is installed at the top end of the lifting end. An installation cavity is formed in the side wall of the main support block. Movable cavities are installed at equal intervals inside the installation cavity. An extension block is movably connected to one end of each movable cavity. A secondary support block is installed at one end of each extension block, and a pad is installed at the top end of each secondary support block.

[0009] Preferably, the top of the lifting end is provided with a slot, and a locking block is engaged inside the top of the slot, the locking block being installed at the bottom of the main support block.

[0010] Preferably, the top end of the main support block is in close contact with the bottom end of the silicone anti-slip pad, and the diameter of the outer wall of the top end of the main support block is the same as the diameter of the outer wall of the bottom end of the silicone anti-slip pad.

[0011] Preferably, flexible sheets are symmetrically installed inside the active cavity, and first limiting protrusions are installed at equal intervals on the corresponding outer walls of the flexible sheets. The outer walls of the first limiting protrusions abut against the outer walls of the second limiting protrusions, and the second limiting protrusions are installed at equal intervals on the outer walls of both sides of the extension block.

[0012] Preferably, each base has a connecting cavity installed at its bottom end, and a connecting seat is installed on the outer wall of the bottom end of the connecting cavity. The top of the connecting seat has through holes at equal intervals, and a plug is movably connected inside the top of the through hole.

[0013] Preferably, a balloon is installed inside the bottom end of the connecting cavity, and the balloon is an inflatable structure.

[0014] Preferably, the bottom end of the balloon is connected to the top end of the silicone wear-resistant layer, and the diameter of the outer wall of the bottom end of the balloon is the same as the diameter of the outer wall of the top end of the silicone wear-resistant layer. The diameter of the outer wall of the bottom end of the balloon is smaller than the inner diameter of the bottom end of the connecting cavity.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. The support system of this utility model, consisting of a main support block and a secondary support block, is flexible and stable. The main support block is quickly engaged with the lifting end slot via a locking block, and is equipped with a silicone anti-slip pad to diffuse the lifting force, increase the contact area, and prevent slippage. When facing a large lifting surface, the extension block can extend from the movable cavity to drive the secondary support block to fit. Automatic positioning is achieved by the outer wall of the first limiting protrusion abutting against the outer wall of the second limiting protrusion, realizing multi-point support and ensuring safe and stable operation under various working conditions.

[0017] 2. During use, when operating on uneven hard surfaces, the ball at the bottom of the device and the silicone wear-resistant layer form an intelligent fit. The silicone wear-resistant layer, with its high elasticity and strong wear resistance, tightly wraps around the raised parts of the ground, simultaneously squeezing the ball to produce adaptive deformation, transforming the irregular surface into a stable support surface. This effectively eliminates the risk of swaying caused by ground undulations, ensuring stable operation of the device. In soft environments such as soil sections, the deep anchoring system composed of the press-type insertion piles and through holes provides a solid guarantee for safe operation. This dual-effect stable design allows the device to maintain reliable performance under various extreme working conditions, significantly reducing operational risks and greatly improving work efficiency.

[0024] 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.

[0025] Please see Figure 1-5 An ultra-thin jack includes an ultra-thin jack body 1. The ultra-thin jack body 1 consists of at least a cylinder, a piston, a lifting end 3, and a sealing device. The lifting end 3 is movably connected to the top of the ultra-thin jack body 1, and a slot 4 is provided at the top of the lifting end 3. A locking block 5 is locked inside the top of the slot 4, and the top of the locking block 5 is fixedly connected to the bottom of the main support block 6. A silicone anti-slip pad 7 is fixedly connected to the top of the main support block 6, and the diameter of the outer wall of the top of the main support block 6 is the same as the diameter of the outer wall of the bottom of the silicone anti-slip pad 7.

[0026] During the use of the device, depending on factors such as the weight and mass of the object being lifted, the main support block 6 can be engaged with the top of the slot 4 opened at the top of the lifting end 3 via the locking block 5, so that the force of the lifting end 3 can be diffused. Thus, the main support block 6, in conjunction with the silicone anti-slip pad 7, expands the contact area with the lifting area of ​​the object being lifted, thereby improving stability.

[0027] The main support block 6 has an annular mounting cavity 8 inside its side wall. The bottom of the mounting cavity 8 is fixedly connected to a movable cavity 9 at equal intervals. Flexible sheets 10 are symmetrically fixedly connected inside the movable cavity 9. The outer walls of the corresponding flexible sheets 10 are fixedly connected to a first limiting protrusion 11 with a semi-cylindrical structure at equal intervals. The outer walls of the first limiting protrusion 11 abut against the outer walls of the second limiting protrusion 13 with a semi-cylindrical structure. The second limiting protrusion 13 is fixedly connected to the outer walls of the two sides of the extension block 12 at equal intervals. One end of the extension block 12 is movably connected to the inside of one end of the movable cavity 9. The other end of the extension block 12 is fixedly connected to a secondary support block 14. A pad 15 is fixedly connected to the top of the secondary support block 14. The diameter of the outer wall of the pad 15 is smaller than the diameter of the outer wall of the top of the secondary support block 14.

[0028] During use, if the lifting surface of the object being lifted is too large, this device can extend the extension block 12 from the inside of the movable cavity 9 to improve stability during the lifting process. This allows the auxiliary support block 14 and the pad block 15 to come into contact with the lifting surface of the object being lifted. After the extension block 12 moves, it comes into contact with the outer wall of the first limiting protrusion 11 and the outer wall of the second limiting protrusion 13 through the outer wall of the first limiting protrusion 11, thereby achieving self-limitation. By adopting this method, the contact area can be expanded through multi-point support, further forming a stable support system.

[0029] The bottom of the ultra-thin jack body 1 is fixedly connected to a base 2, and the bottom of the base 2 is fixedly connected to a connecting cavity 16. The bottom of the connecting cavity 16 is hollow. A connecting seat 17 with a circular structure is fixedly connected to the lower side of the outer wall of the connecting cavity 16. The top of the connecting seat 17 has through holes 18 at equal intervals. The top of each through hole 18 is fixedly connected to a plug 19. The top of the inside of the connecting cavity 16 is fixedly connected to an inflatable balloon 20. The bottom of the balloon 20 is tightly fitted with a silicone wear-resistant layer 21. The diameter of the outer wall of the bottom of the balloon 20 is the same as the diameter of the outer wall of the top of the silicone wear-resistant layer 21. The diameter of the outer wall of the bottom of the balloon 20 is smaller than the inner diameter of the bottom of the connecting cavity 16.

[0030] When placing the device on the ground for use, considering the working environment of this device, the placement area may be uneven. This device uses a balloon 20 and a silicone wear-resistant layer 21 to wrap around the raised parts of the placement area, thereby squeezing the balloon 20 to deform, so as to make the device more level during placement and use, and improve the stability of the device during use. At the same time, when used on soil sections, the insertion stake 19 can be pressed to make the insertion stake 19 move inside the top of the through hole 18 until the insertion stake 19 is inserted into the soil, so as to strongly fix the device, thus making it more stable during use.

[0031] The specific usage process in this embodiment is as follows:

[0032] First, the device is placed on the ground for use. The balloon 20, together with the silicone wear-resistant layer 21, wraps around the protruding parts of the placement area, thereby squeezing the balloon 20 to deform, so that the device can be placed and used more smoothly.

[0033] Secondly, when used on soil sections, the insertion stake 19 can be pressed to move inside the top of the through hole 18 until the insertion stake 19 is inserted into the soil, thus providing strong fixation for the device.

[0034] Subsequently, based on factors such as the weight and mass of the object being lifted, the main support block 6 can be engaged with the slot 4 at the top of the lifting end 3 via the locking block 5, thereby dispersing the force of the lifting end 3 and expanding the contact area between the main support block 6 and the lifting area of ​​the object being lifted through the cooperation of the silicone anti-slip pad 7.

[0035] Finally, in order to improve the stability during the lifting process, the extension block 12 can be extended outward from the inside of the movable cavity 9, so that the auxiliary support block 14 and the pad block 15 come into contact with the lifting surface of the object being lifted. After preparation, the lifting operation is completed by controlling the ultra-thin jack body 1. In this way, the ultra-thin jack is used.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
