The wall sleeve is firmly constructed, the end face is close to the wall beam surface, the visual quality is good, the construction speed is fast, the versatility is strong, it can be reused, and the cost is low.

[0003] However, there are some problems with the prior art: the existing sleeve is usually set in the installation hole, and is threadedly connected to other pipes through the threads on the sleeve. Since the connection is in the hole, the construction workers cannot align it with the naked eye, and the diameters of the connection between the two pipes are similar, which can easily lead to misalignment when connecting them, wasting construction time. Therefore, we propose a sleeve with a positioning mechanism. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a sleeve with a positioning mechanism, through which the sleeve can be aligned when connected to other pipelines to prevent misalignment and increase the connection speed.

DETAILED DESCRIPTION

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a sleeve with a positioning mechanism provided by an embodiment of the utility model includes a sleeve shell 1. The sleeve shell 1 is cylindrical as a whole and is made of stainless steel to ensure that the sleeve shell 1 will not be corroded during long-term use. Of course, the shape of the sleeve shell 1 is not limited to a cylindrical shape, and can also be other shapes such as a rectangle. The sleeve shell 1 can be divided into two parts, one part has a smooth outer wall, and the other part has an outer wall with threads. The diameter of the threaded part is slightly smaller than that of the smooth outer wall part. The two parts are fixedly connected by welding, and the sleeve shell 1 mainly plays a protective role.

[0026] A cavity is opened in the sleeve shell 1, and a positioning cylinder 2 is fixedly connected to the inner wall of the cavity. The outer diameter of the positioning cylinder 2 is the same as the inner diameter of the sleeve shell 1. The outer wall of the positioning cylinder 2 completely fits on the inner wall of the sleeve shell 1. Both ends of the positioning cylinder 2 are opened to ensure internal circulation. The positioning cylinder 2 is also made of stainless steel to prevent corrosion.

[0027] A positioning block 3 is rotatably connected to one end of the positioning cylinder 2. The positioning block 3 is arc-shaped and made of stainless steel. The positioning block 3 is connected to the positioning cylinder 2 at a certain angle. The length of the positioning block 3 gradually decreases as it moves away from the positioning cylinder 2. Four groups of positioning blocks 3 are provided. Of course, the number of positioning blocks 3 is not limited to four groups, and can also be set to five groups, six groups, etc. Each group of positioning blocks 3 is evenly distributed on one end of the positioning cylinder 2 in a circle. The main function of the positioning block 3 is to perform positioning when the sleeve housing 1 is connected to the connecting pipe 9 to prevent misalignment during connection.

[0028] A connecting block 6 is fixedly connected to one side of the positioning cylinder 2 , and a rotating shaft 7 is fixedly connected to the connecting block 6 . The rotating shaft 7 is rotatably connected in a groove of the positioning block 3 , and the positioning block 3 can rotate around the rotating shaft 7 .

[0029] A positioning ring 11 is fixedly connected to one end of the positioning block 3. The positioning ring 11 is also arc-shaped and made of stainless steel. The main function of the positioning ring 11 is to guide the positioning block 3 to be inserted into the connecting pipe 9, so that when the sleeve housing 1 is connected to the connecting pipe 9, the positioning block 3 can be inserted into the connecting pipe 9 more quickly to position the connection.

[0030] A stopper 4 is fixedly connected to one side of the positioning block 3, and the stopper 4 is used to drive the positioning block 3 to rotate. The stopper 4 is arranged in a triangle, wherein the inclined surface of the stopper 4 faces outward, so that when the sleeve housing 1 is connected to the connecting pipe 9, the connecting pipe 9 can better push the stopper 4, thereby driving the positioning block 3 to rotate.

[0031] A groove is provided in the positioning block 3, and a rebound component 5 is arranged in the groove. The rebound component 5 is used to reset the positioning block 3. The rebound component 5 includes a sleeve 501, and the sleeve 501 is fixedly connected to the outer wall of the rotating shaft 7. The outer wall of the sleeve 501 is wrapped with an elastic steel coil 502, and the elastic steel coil 502 can undergo elastic deformation, thereby rotating.

[0032] One end of the elastic steel coil 502 is fixedly connected to the outer wall of the sleeve 501, and the other end of the elastic steel coil 502 is fixedly connected to the inner wall of the groove of the positioning block 3. The elastic steel coil 502 is used to drive the positioning block 3 to rotate. Both ends of the sleeve 501 are fixedly connected to the limiting ring 503. The elastic steel coil 502 is arranged between the two groups of limiting rings 503. The limiting ring 503 is used to limit the movement of the elastic steel coil 502. The limiting ring 503 is made of stainless steel material. Its main function is to prevent the elastic steel coil 502 from detaching from the sleeve 501 due to elasticity after being tightened, causing the elastic steel coil 502 to be in disorder.

[0033] When the connecting tube 9 is connected to the sleeve housing 1, the positioning block 3 can be accurately inserted into the connecting tube 9 due to the smaller diameter of one end. When the connecting tube 9 moves inward, the connecting tube 9 will push the stopper 4, thereby driving the positioning block 3 to overcome the elasticity of the elastic steel coil 502 and rotate. When the outer surface of the positioning block 3 fits against the outer wall of the connecting tube 9, the positioning block 3 will stop rotating.

[0034] When the connecting pipe 9 is detached from the sleeve housing 1, the stop block 4 is no longer subjected to force, and the elastic steel coil 502 is also no longer subjected to force, so that the elastic steel coil 502 rebounds and rotates. The rotation of the elastic steel coil 502 will drive the rotating shaft 7 to rotate, and the rotating shaft 7 will drive the positioning block 3 to rotate. At the same time, the rotation of the rotating shaft 7 will also drive the limit block 8 to rotate. When the limit block 8 rotates to the edge of the sliding groove of the positioning block 3, it will encounter resistance and cannot rotate. At this time, the rotating shaft 7 stops rotating, and the positioning block 3 also stops rotating, so that the positioning block 3 just returns to its original state and waits for the next connection.

[0035] A limit block 8 is slidably connected in the groove, and a slideway is provided on the inner wall of the groove of the positioning block 3. The limit block 8 is slidably connected in the slideway. One end of the limit block 8 is fixedly connected to the rotating shaft 7. The limit block 8 is used to limit the rotation of the positioning block 3. When the positioning block 3 rotates, the limit block 8 on the rotating shaft 7 will slide in the slideway on the positioning block 3, so that when the elastic steel coil 502 rebounds and drives the positioning block 3 to rotate, the limit block 8 limits the positioning block 3, that is, when the limit block 8 slides to the edge of the slideway of the positioning block 3, the limit block 8 can no longer slide, and the positioning block 3 can also not move. At this time, the positioning block 3 is just in the initial position.

[0036] The outer wall of one end of the sleeve housing 1 is threadedly connected to a connecting pipe 9, the threaded portion of the sleeve housing 1 is connected to the connecting pipe 9, and the diameter of the other smooth portion is slightly larger than the threaded portion, which is just used for limiting. A sealing ring 10 is arranged between the sleeve housing 1 and the connecting pipe 9. The sealing ring 10 is annular and is made of rubber material. The main function of the sealing ring 10 is to prevent objects in the sleeve housing 1 from leaking out.

[0037] The positioning block 3 and the positioning ring 11 are arc-shaped, and the outer surfaces of the positioning block 3 and the positioning ring 11 fit with the inner wall of the connecting tube 9. When the connecting tube 9 is connected to the sleeve shell 1, the connecting tube 9 pushes the positioning block 3 to rotate, and the positioning block 3 will rotate to fit the surface of the connecting tube 9, thereby ensuring the smooth flow of the connecting tube 9 and avoiding the positioning block 3 from affecting the circulation of items in the connecting tube 9.

[0038] The working principle of the utility model is as follows:

[0039] The utility model is fixedly connected with a positioning cylinder 2 in the casing shell 1, and a positioning block 3 is rotatably connected to the positioning cylinder 2. When the casing shell 1 is connected to the connecting pipe 9, the end of the positioning block 3 connected to the positioning ring 11 has a smaller diameter and can be directly and accurately inserted into the connecting pipe 9. As the connecting pipe 9 moves inward, the inner diameter of the positioning block 3 gradually increases, so that the connecting pipe 9 can be accurately connected to the casing shell 1. During the connection process, as the connecting pipe 9 gradually approaches the casing shell 1, the connecting pipe 9 will push the stopper 4 to move inward, and the stopper 4 will be forced to move, which will drive the positioning block 3 to overcome the elastic force of the elastic steel coil 502 and rotate, so that the positioning When the connecting tube 9 is removed, as the connecting tube 9 gradually moves away from the sleeve shell 1, the stopper 4 is no longer subjected to force, and the elastic steel coil 502 is no longer subjected to force, and the elastic steel coil 502 will rebound, thereby driving the positioning block 3 to rotate on the rotating shaft 7, and the limit block 8 on the rotating shaft 7 will also slide in the slideway on the positioning block 3. When the limit block 8 slides to the edge of the slideway, it can no longer slide, and the positioning block 3 can no longer rotate. At this time, the positioning block 3 is just in the initial position, and the above operation can be repeated to complete the connection of other connecting tubes 9 with the sleeve shell 1.
