Description

Technical Field

[0001] This utility model belongs to the field of pipe joints, specifically relating to a structure for an anti-detachment hexagonal external thread joint. Background Technology

[0002] Hexagonal male threaded fittings are pipe fittings with threads. They are one of the most common types of pipe fittings in industry and daily life. Hexagonal male threaded fittings make pipe connections simpler and disassembly and replacement easier, greatly saving the cost of pipe connections.

[0003] During the use of hexagonal male threaded connectors, the pipeline may be pulled by external forces, and the medium may vibrate during pipeline transportation, causing the hexagonal male threaded connector or pipeline to reverse, resulting in loosening between the hexagonal male threaded connector and the pipeline. This leads to unstable medium transportation pressure or leakage. Therefore, an anti-loosening hexagonal male threaded connector structure is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a hexagonal external thread connector structure to prevent detachment.

[0005] To achieve the above objectives, this utility model provides an anti-loosening hexagonal external thread connector structure, including a nut sleeve with several grooves on both sides; a resistance-increasing element is slidably arranged inside the groove to increase the resistance between the connector and the external pipe fitting, preventing reverse loosening.

[0006] Two studs are respectively located on both sides of the nut sleeve and connected to the nut sleeve, for connecting to external pipes;

[0007] Several mounting slots are respectively opened on the outer wall plane of the nut sleeve;

[0008] The mounting slot is equipped with an adjusting component, which is connected to two resistance-increasing components on the left and right. This component is used to adjust the position of the resistance-increasing components and the coefficient of friction between them and the external pipe fittings.

[0009] Furthermore, the groove is an arc-shaped groove, and the resistance-increasing component includes an arc-shaped plate that can be slidably disposed inside the groove, the arc-shaped plate being adapted to the groove; and several spikes disposed on the outer wall of the arc-shaped plate.

[0010] Furthermore, the adjusting component includes a base disposed inside the mounting groove; two threaded rods respectively disposed on the left and right sides of the base, one end of the threaded rod being inserted into the base and threadedly connected, and the other end being rotatably connected to the adjacent arc-shaped plate.

[0011] Furthermore, a locking ring is provided on the threaded sleeve on the outer wall of the threaded rod. The locking ring can abut against the outer wall of the base to limit the threaded rod and prevent loosening.

[0012] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0013] The anti-loosening hexagonal external threaded connector structure of this utility model allows the resistance-increasing components on both sides to extend and contact the external pipeline through the adjustment component. By increasing the resistance between the external pipeline and the hexagonal external threaded connector, the phenomenon of reverse loosening between the connector and the pipeline can be prevented. At the same time, the extension distance of the resistance-increasing components can be adjusted by the adjustment component, thereby changing the pressure applied to the pipeline by the resistance-increasing components to adjust the resistance, thereby improving the anti-loosening effect.

[0018] 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.

[0019] Please see Figure 1-3 In this embodiment, the anti-loosening hexagonal external threaded connector structure allows the resistance-increasing components 3 on both sides to extend and contact the external pipe through the adjusting component 6. By increasing the resistance between the external pipe and the hexagonal external threaded connector, reverse loosening between the connector and the pipe can be prevented. At the same time, the extension distance of the resistance-increasing component 3 can be adjusted through the adjusting component 6, thereby adjusting the resistance by changing the pressure applied to the pipe by the resistance-increasing component 3, thus improving the anti-loosening effect.

[0020] Specifically, it includes a nut sleeve 1, with several grooves 2 on both sides of the nut sleeve 1; a resistance-increasing element 3 is slidably provided inside the groove 2 to increase the resistance between the nut sleeve 1 and the external pipe fittings and prevent reverse loosening.

[0021] Two studs 4 are respectively set on both sides of the nut sleeve 1 and connected to the nut sleeve 1, for connecting to external pipes;

[0022] Several mounting slots 5 are respectively opened on the outer wall plane of the nut sleeve 1;

[0023] The mounting slot 5 is equipped with an adjusting component 6, which is connected to two left and right resistance increasing components 3. It is used to adjust the position of the resistance increasing components 3 and the coefficient of friction between them and the external pipe fittings.

[0024] In this embodiment, when needed, the two studs 4 can be connected to two external pipes. Then, the adjusting member 6 extends the resistance-increasing members 3 on both sides and contacts the external pipes. By increasing the resistance between the external pipes, the phenomenon of reverse loosening between the hexagonal external threaded joint and the pipes can be prevented. At the same time, the extension distance of the resistance-increasing member 3 can be adjusted by the adjusting member 6, and the resistance can be adjusted by changing the pressure applied to the pipe by the resistance-increasing member 3, thereby improving the anti-loosening effect.

[0025] Specifically, refer to Figure 1 and Figure 3 The groove 2 is an arc-shaped groove, and the resistance-increasing component 3 includes an arc-shaped plate 31 that is slidably disposed inside the groove 2, the arc-shaped plate 31 being adapted to the groove 2; and a number of spikes 32 disposed on the outer wall of the arc-shaped plate 31.

[0026] In this embodiment, when the arc plate 31 is pushed out by the adjusting member 6, the spike 32 can be pressed against or inserted into the external pipe. The biting force formed by the spike 32 increases the resistance between the spike and the pipe. The arc-shaped design of the arc plate 31 can also better adapt to the curvature of the pipe and increase the contact area between the spike 32 and the pipe.

[0027] Specifically, refer to Figure 2-3 The adjusting component 6 includes a base 61 disposed inside the mounting groove 5; and two threaded rods 62 disposed on the left and right sides of the base 61 respectively. One end of the threaded rod 62 is inserted into the base 61 and threadedly connected, and the other end is rotatably connected to the adjacent arc plate 31.

[0028] In this embodiment, during use, the threaded rod 62 can be screwed on by an external wrench. During this process, the threaded engagement between the threaded rod 62 and the base 61 allows the threaded rod 62 to push the arc plate 31 outward to achieve the above-mentioned effect.

[0029] Specifically, refer to Figure 2-3 The threaded rod 62 is threaded with a locking ring 7 on its outer wall. The locking ring 7 can abut against the outer wall of the base 61 to limit the threaded rod 62 and prevent it from loosening.

[0030] In this embodiment, after the threaded rod 62 is adjusted to the working position, the locking ring 7 can be screwed until it contacts the outer wall of the base 61. The locking ring 7 can limit the threaded rod 62 and prevent the threaded rod 62 from rotating and retracting into the base 61.

[0031] 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
