Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, and more specifically, it relates to a deformation-proof sleeve. Background Art

[0002] A sleeve is an extended hexagonal ring used to tighten or loosen fasteners such as bolts and nuts, usually made of metal materials. It can be used in manual or electric tools. Appropriate sleeve sizes are selected for operation according to needs. The sleeve usually cooperates with a handle. People insert the handle into one end of the sleeve and then use the other end of the sleeve to operate the nut. When people use the sleeve to disassemble bolts and nuts, they will put the sleeve on the nut and then rotate the handle to drive the sleeve to rotate, thereby driving the nut to rotate. Since the range of motion of people's arms is limited, people need to repeat the above operations. During the process of disassembling the nut with the handle and the sleeve, the friction between the nut and the sleeve will cause the sleeve and the handle to separate, thus affecting the disassembly efficiency.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a deformation-proof sleeve.

Rubber soft pads are bonded to the sides of the two clamping arms facing each other.

[0006] The utility model is further arranged as: when the clamping arm rotates to the top surface of the cylinder body, the side surface of the clamping arm is in the same plane as the side surface of the cylinder body.

[0007] The utility model is further arranged as: an embedding groove for accommodating the positioning hoop to be embedded is opened on the clamping arm. The two clamping arms are relatively fixed by embedding the positioning hoop into the embedding groove, and a positioning groove for accommodating the positioning hoop to be embedded is opened on the outer side wall of the cylinder body.

[0008] The utility model is further arranged as: the cross-section of the positioning hoop is circular, and guiding arc surfaces communicating the positioning groove and the embedding groove are respectively arranged on the cylinder body and the clamping arm.

[0009] The utility model is further arranged as: a plurality of magnetic blocks are arranged on both the cylinder body and the clamping arm, and the cylinder body and the clamping arm are fixed by mutual adsorption of the magnetic blocks.

[0010] The utility model is further configured that: a clamping block is detachably connected to the positioning hoop, and a groove for clamping the positioning hoop is formed in the clamping block.

[0011] The utility model is further configured that: two symmetrically arranged arc grooves which can accommodate the positioning hoop to be embedded are formed in the inner wall of the groove.

[0012] The utility model is further configured that: the cylinder body is made of stainless steel material.

[0013] To sum up, the utility model has the following beneficial effects: by arranging the clamping arms, the clamping arms can increase the contact area with the handle, thereby improving the friction force between the two, making it not easy for the arm to separate from the cylinder body; by arranging the clamping grooves, the clamping grooves can play a certain limiting and guiding role for the handle, making the cylinder body stable during rotation and not slipping, improving the disassembly efficiency; by arranging the positioning hoop, the positioning hoop can play a positioning effect, improving the clamping effect of the two clamping arms.

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] Embodiment:

[0020] An anti-deformation sleeve, as Figure 1 and Figure 2As shown in the figure, it includes a cylinder body 1 made of stainless steel material. One end of the cylinder body 1 is provided with a card slot 2 for accommodating the insertion of a handle, and the other end of the cylinder body 1 is provided with a hexagonal hole for accommodating the insertion of a nut. The handle and the nut are common operating components of the sleeve. The designs of the card slot 2 and the hexagonal hole enable the handle and the nut to be firmly inserted into the sleeve, not easily falling off, facilitating the operation of the user. Moreover, the stainless steel material has good wear resistance and corrosion resistance, which can ensure that the sleeve is not easily worn and corroded during use, thereby extending its service life. At the same time, the stainless steel material has the characteristic of high strength, which can ensure the strength of the sleeve and is not easily deformed.

[0021] As Figure 1 , Figure 2 and Figure 3 shown in the figure, two symmetrically arranged clamping arms 3 are rotatably connected to the side of the sleeve close to the card slot 2. A positioning hoop 4 for restricting the rotation of the clamping arms 3 is detachably connected to the two clamping arms 3. Rubber soft pads 5 are bonded to the sides of the two clamping arms 3 facing each other. By setting the clamping arms 3, the clamping arms 3 can increase the contact area with the handle, thereby increasing the friction between the two, making it not easy for the arm to separate from the cylinder body 1. By setting the card slot 2, the card slot 2 can play a certain limiting and guiding role for the handle, making the cylinder body 1 stable during rotation without slipping, improving the disassembly efficiency. By setting the positioning hoop 4, the positioning hoop 4 can play a positioning effect, improving the clamping effect of the two clamping arms 3. At the same time, the rubber soft glue can further increase the friction between the clamping arms 3 and the handle, thereby improving the connection strength between the two. Moreover, the rubber soft glue has a certain elasticity, which can protect the handle and the clamping arms 3, avoiding rigid collision between the two and extending the service life of the sleeve. When the clamping arms 3 rotate to the top surface of the cylinder body 1, the side surface of the clamping arms 3 is in the same plane as the side surface of the cylinder body 1, making it convenient for the positioning hoop 4 to slide and tighten the clamping arms 3 when people clamp the handle. At the same time, the clamping arms 3 are flush with the side surface of the cylinder body 1, which can make the overall appearance more neat and beautiful, enhancing the visual effect.

[0022] As Figure 1 , Figure 2 and Figure 3As shown in the figure, the clamping arm 3 is provided with an embedding groove 6 for the positioning hoop 4 to be embedded. The two clamping arms 3 are relatively fixed by embedding the positioning hoop 4 into the embedding groove 6. A positioning groove 7 for the positioning hoop 4 to be embedded is provided on the outer side wall of the cylinder body 1. By providing the embedding groove 6 and the positioning groove 7, when the positioning hoop 4 is respectively embedded into the embedding groove 6 and the positioning groove 7, the connection strength between the positioning hoop 4 and the clamping arm 3 and the cylinder body 1 can be improved, the stability of the positioning hoop 4 is improved, and the positioning hoop 4 is prevented from shaking. Further, the cross section of the positioning hoop 4 is circular. The cylinder body 1 and the clamping arm 3 are respectively provided with a guiding arc surface 8 communicating the positioning groove 7 and the embedding groove 6. Through the above setting, the design of the guiding arc surface 8 enables the positioning hoop 4 to be smoothly embedded into the embedding groove 6 and the positioning groove 7, simplifies the operation steps, improves the work efficiency, and the positioning hoop 4 with a circular cross section can be applied to clamping arms 3 and cylinder bodies 1 of different sizes, enhancing the versatility and flexibility of the design.

[0023] As Figure 2 and Figure 3 shown in the figure, a plurality of magnetic blocks 9 are provided on both the cylinder body 1 and the clamping arm 3. The cylinder body 1 and the clamping arm 3 are fixed by mutual adsorption of the magnetic blocks 9. By providing the magnetic blocks 9, when people do not use the anti-deformation sleeve, the clamping arm 3 can be rotated to fit the outer wall of the cylinder body 1. At this time, the magnetic blocks 9 on the cylinder body 1 will adsorb with the magnetic blocks 9 on the clamping arm 3, so that the clamping arm 3 is kept fixed with the cylinder body 1, preventing the clamping arm 3 from shaking when people move the anti-deformation sleeve, reducing the collision between the clamping arm 3 and the cylinder body 1, and prolonging the service life of the anti-deformation sleeve.

[0024] As Figure 1 and Figure 2 shown in the figure, a clamping block 10 is detachably connected to the positioning hoop 4. The clamping block 10 is provided with a groove 11 for clamping the positioning hoop 4. Two symmetrically arranged circular arc grooves 12 for the positioning hoop 4 to be embedded are provided on the inner wall of the groove 11. By providing the clamping block 10 and the groove 11, after the positioning hoop 4 is embedded into the embedding groove 6, the clamping block 10 can be clamped at both ends of the positioning hoop 4. At this time, the binding effect of the positioning hoop 4 is better, improving the connection strength between the clamping arm 3 and the handle. By providing the circular arc grooves 12, the circular arc grooves 12 can fit the positioning hoop 4, preventing the positioning hoop 4 from shaking in the groove 11, improving the connection strength between the clamping block 10 and the positioning hoop 4, and making the anti-deformation sleeve more stable during use.
