Description

Technical Field

[0001] The present application relates to the technical field of composite sleeves, and in particular to a composite sleeve. Background Art

[0002] A wrench socket, as the name implies, is a tool designed to be put on a bolt or nut and rotated by a wrench or other torque tool to achieve tightening or loosening operations. It is usually made of high-quality metal materials (such as chrome vanadium steel, stainless steel, etc.) to ensure sufficient hardness and durability. Structurally, a wrench socket usually includes a hexagonal, dodecagonal or other polygonal inner hole to match the head of the bolt or nut, and an outer smooth cylindrical body to facilitate the clamping of a wrench or socket wrench; a wrench composite socket, as the name implies, is an innovative tool that combines the advantages of a traditional wrench and a socket wrench. It usually consists of a handle (or main body) and multiple replaceable socket heads. These socket heads are of different sizes and can adapt to bolts and nuts of different specifications, while the handle integrates the function of a wrench, which can tighten or loosen the bolt by rotating the handle. What is more worth mentioning is that the composite socket is often equipped with a quick-change mechanism, which makes the replacement of the socket head easy and quick, greatly improving work efficiency; the existing composite sockets are all fixed with bolts, and the internal opening diameter and length are fixed, but the bolts that need to be removed are of different sizes, resulting in a wrench socket with a diameter hole that can only be suitable for bolts of one size. Removing it limits the function of the composite socket, and it cannot adapt to the volume of the bolt to adjust the clamping position corresponding to the socket. Utility Model Content

[0019] The following is combined with Figures 1-4 This application is described in further detail.

[0020] An embodiment of the present application discloses a composite sleeve. Referring to Figure 3 and Figure 4 , it includes a first sleeve 1. A placement groove 100 is provided on the top surface of the first sleeve 1. Threaded rods 2 are installed on both sides of the first sleeve 1. One end of each threaded rod 2 penetrates through the outside of the first sleeve 1 and is connected to a contact plate 3 in a butting manner. Four telescopic rods 4 are fixedly installed on one side of the contact plate 3. One end of each of the four telescopic rods 4 is fixedly installed on the inner side wall of the first sleeve 1. A rotary handle 5 is welded to one side of the threaded rod 2. The outer diameter of the first sleeve 1 is 40 mm. By sleeving the placement groove 100 of the first sleeve 1 on the outside of an external bolt, and then using the rotary handle 5 to make the threaded rod 2 pass through the first sleeve 1 to push the contact plate 3 to move. When the contact plate 3 moves, the telescopic rods 4 slide and extend. Following the movement of the contact plate 3, further, a sliding rod 6 moves. The outside of the sliding rod 6 slides along the sliding hole of the first sleeve 1. The contact plate 3 contacts the outside of the contact bolt and clamps the bolt. Then rotate the first sleeve 1 to rotate the bolt. After rotating multiple times, the bolt is pulled out, achieving the effect of adjusting the clamping position according to the volume of the square head bolt.

[0021] Referring to Figure 4 , sliding holes are provided on both sides of the first sleeve 1. The inner side walls of the two sliding holes are sleeved with sliding rods 6. One end of each of the two sliding rods 6 penetrates through the outside of the first sleeve 1 and is connected to the contact plate 3. The sliding rods 6 play a role in preventing the telescopic rods 4 from falling off during the movement of the contact plate 3, resulting in the unstable structure of the contact plate 3 and affecting the structural stability.

[0022] Referring to Figure 2 , two clamping positions 300 are provided on the inner side wall of the placement groove 100 of the first sleeve 1. The areas of the two clamping positions 300 are equal to that of the contact plate 3. Rotate the threaded rod 2 to move the contact plate 3, further causing the telescopic rods 4 to contract towards the clamping positions 300. The sliding rods 6 slide along the sliding holes of the first sleeve 1, making the contact plate 3 engage with one side of the clamping positions 300, making the diameter area of the placement groove 100 of the first sleeve 1 complete, facilitating the sleeving of the placement groove 100 of the first sleeve 1 on the outside of the bolt, and being beneficial for adjusting the clamping position according to the volume of the bolt.

[0023] Referring to Figure 3 , threads are provided on the outside of the first sleeve 1. A second sleeve 7 is threadedly installed at the bottom end of the first sleeve 1. Square holes 700 are provided on both sides of the second sleeve 7. Move the bottom end of the first sleeve 1 along the inner side wall of the second sleeve 7 and rotate it to fix the first sleeve 1 and the second sleeve 7.

[0024] Referring to Figure 1 , threads are provided on the lower half of the first sleeve 1. The threads are beneficial for the connection between the first sleeve 1 and the second sleeve 7.

[0025] Referring to Figure 1The outer diameter of sleeve 27 is 50mm. A threaded sleeve rod can be installed at the bottom of sleeve 27. The threaded sleeve rod passes through sleeve 27 and is connected and rotated with sleeve 1, which is beneficial to strengthen the structure and prevent sleeve 27 from separating from sleeve 1 during rotation, thereby affecting work efficiency.

[0026] The implementation principle of a composite sleeve in the embodiment of the present application is as follows: first, the threaded rod 2 is rotated to move the contact plate 3, and further the telescopic rod 4 is retracted towards the locking position 300. Secondly, the sliding rod 6 slides along the sliding hole of the sleeve 1, so that the contact plate 3 is engaged with one side of the locking position 300, so that the diameter area of ​​the placement groove 100 of the sleeve 1 is complete, which is convenient for the placement groove 100 of the sleeve 1 to be sleeved on the outside of the bolt, which is conducive to following the volume of the bolt. Finally, by sleeveing ​​the placement groove 100 of the sleeve 1 on the outside of the external bolt, and then turning the handle 5 to make the threaded rod 2 pass through the sleeve 1 to push the contact plate 3 to move, the contact plate 3 moves to make the telescopic rod 4 slide and extend, follow the movement of the contact plate 3, further move the sliding rod 6, the outer side of the sliding rod 6 slides along the sliding hole of the sleeve 1, the contact plate 3 contacts the outer side of the contact bolt and clamps the bolt, and then the sleeve 1 is rotated to make the bolt rotate. After multiple rotations, the bolt is pulled out, so as to achieve the effect of adjusting the clamping position according to the volume of the square head bolt.
