Description

Technical Field

[0001] This utility model relates to the field of nut connector sleeve technology, and in particular to an airtight and waterproof nut connector sleeve that is easy to install. Background Technology

[0002] As an important connecting component, the airtight and waterproof nut connector plays a crucial role in many fields. Utilizing a special structural design, it achieves reliable airtightness and waterproof performance, ensuring the sealing and stability of the connection. In practical applications, the airtight and waterproof nut connector typically requires the use of the following technologies:

[0003] 1. The precision threaded structure ensures a tight and airtight connection between the nut and the connecting sleeve body through a high-precision thread fit. The thread parameters are designed to take into account different usage scenarios and pressure requirements to achieve the best connection effect.

[0004] 2. Effective sealing methods can utilize sealing gaskets, sealants, and other sealing elements to tightly fill gaps in the connection points and prevent gas or liquid leakage. The material selection for the sealing elements should be based on the characteristics of the operating environment.

[0005] Currently, manufacturers have adopted various connector designs and methods to achieve good airtight and waterproof connections. Some manufacturers use traditional non-removable connectors, which require complete replacement if any part is damaged, increasing maintenance costs and wasting resources. Other manufacturers use complex sealing structures, but these are difficult to install and disassemble, making them unsuitable for practical operation and maintenance. Some manufacturers focus on the appearance design of the connectors, but lack in actual performance and maintainability.

[0006] However, the above-described implementation still has the following problems. In terms of installation convenience, traditional connecting sleeves may require greater installation force and complex installation steps, increasing installation difficulty and time costs. In terms of maintenance, the non-removable connecting sleeve or the difficult-to-disassemble design makes the maintenance process complex and costly. When a part of the connecting sleeve is damaged, it cannot be replaced individually; the entire body must be replaced, which not only increases costs but may also affect the normal operation of the equipment. To address this problem, this application proposes a solution: designing an airtight and waterproof nut connecting sleeve with a pointed tip for easy installation and overall detachability. This connecting sleeve is easy to install, and the pointed tip structure can guide the insertion operation, improving installation efficiency. When a part is damaged, it can be replaced individually without replacing the entire body, reducing maintenance costs. This design can meet the needs of different usage scenarios and improve the practicality and reliability of the connecting sleeve. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides an airtight and waterproof nut connector that is easy to install. It solves the problems that traditional connectors may require a large installation force and complex installation steps, increasing installation difficulty and time costs. In terms of maintenance, non-removable connectors or designs that are difficult to disassemble make the maintenance process complicated and costly.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: an airtight and waterproof nut connector sleeve that is easy to install, comprising a sleeve body, a screw threadedly fitted inside the sleeve body, a hexagonal head fixedly connected to the upper surface of the screw, a screw threadedly fitted inside the hexagonal head, a pointed tip movably engaged on the lower surface of the sleeve body, a connecting post and a connecting ring fixedly connected to the upper surface of the pointed tip, a threaded ring threadedly fitted inside the sleeve body, a hexagonal groove formed on the upper surface of the threaded ring, two arc-shaped blocks fixedly connected to the lower surface of the hexagonal head, a threaded post fixedly connected to the upper surface of the connecting post, and the threaded post threadedly fitted into the threaded ring.

[0011] As a preferred embodiment of this utility model, the lower surface of the sleeve is provided with an annular groove and a circular groove, which are respectively movably sleeved with the connecting ring and the connecting post.

[0012] As a preferred embodiment of this utility model, two arc-shaped grooves are formed on the upper surface of the screw, and the two arc-shaped grooves are respectively engaged with two arc-shaped blocks.

[0013] As a preferred technical solution of this utility model, a threaded groove is provided on the upper surface of the screw, and the threaded groove is threadedly connected to the screw.

[0014] As a preferred embodiment of this utility model, a fixing ring is fixedly connected to the annular side of the hexagonal head, and a sealing gasket is attached to the upper surface of the sleeve.

[0015] (III) Beneficial Effects

[0016] 1. The tight connection between the sleeve and the tip is ensured by the connection of the connecting ring and the annular groove. At this time, the threaded ring is threaded into the sleeve by using an Allen wrench. As the threaded ring moves downward, its lower end will be threaded and fixed with the threaded post. At this time, the tip and the sleeve are in a fixed state. By setting the tip, when the sleeve is installed in a softer plate or filling material, the tip can play a guiding role, making it easier to pierce the material surface and allowing the sleeve to enter smoothly. This design reduces the external force required during installation and allows the sleeve to be inserted accurately in the set direction, reducing the difficulty of installation and improving the installation efficiency.

[0017] 2. The hexagonal head engages with two arc-shaped blocks fixed on it and two arc-shaped grooves on the upper end of the screw, ensuring a stable connection. A screw is then fitted inside the hexagonal head, and the bottom end of the screw connects and fixes with the threaded groove on the upper end of the screw. At this point, the hexagonal head and the screw are in a fixed state. A sealing gasket is provided at the connection between the sleeve and the screw to ensure airtightness. The entire design is detachable, so if a part is damaged, it can be replaced individually without replacing the entire body, reducing maintenance costs. Attached Figure Description

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the overall concept of the embodiments of this application is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an airtight and waterproof nut connector sleeve that is easy to install. It includes a sleeve body 1, a screw rod 2 threadedly fitted inside the sleeve body 1, a hexagonal head 3 fixedly connected to the upper surface of the screw rod 2, a screw 4 threadedly fitted inside the hexagonal head 3, a pointed tip 7 movably engaged on the lower surface of the sleeve body 1, a connecting post 13 and a connecting ring 14 fixedly connected to the upper surface of the pointed tip 7, a threaded ring 8 threadedly fitted inside the sleeve body 1, a hexagonal groove 9 on the upper surface of the threaded ring 8, two arc-shaped blocks 15 fixedly connected to the lower surface of the hexagonal head 3, and a threaded post 12 fixedly connected to the upper surface of the connecting post 13. The threaded post 12 is threadedly fitted into the threaded ring 8. During installation, the pointed tip 7 is first movably fitted at the lower end of the sleeve body 1. The connecting post 13 and the threaded post 12 on the pointed tip 7 extend into the sleeve body 1. The tightness of the connection between the sleeve body 1 and the pointed tip 7 is ensured by the fitting of the connecting ring 14 and the annular groove 10.

[0028] The lower surface of the sleeve 1 has an annular groove 10 and a circular groove 11, which are movably engaged with the connecting ring 14 and the connecting post 13, respectively. The upper surface of the screw 2 has two arc-shaped grooves 17, which are movably engaged with two arc-shaped blocks 15, respectively. At this time, the threaded ring 8 is threaded into the sleeve 1 using an Allen wrench. As the threaded ring 8 moves downward, its lower end will be threaded and fixed with the threaded post 12. At this time, the tip 7 and the sleeve 1 are in a fixed state. By setting the tip 7, when the sleeve 1 is installed in a softer plate or filling material, the tip 7 can play a guiding role, making it easier to pierce the material surface and allowing the sleeve 1 to enter smoothly. This design reduces the external force required during installation and allows the sleeve 1 to be accurately inserted in the set direction, reducing the difficulty of installation and improving the installation efficiency.

[0029] The upper surface of the screw 2 has a threaded groove 16, which is threadedly connected to the screw 4. The hexagonal head 3 has a fixed ring 5 on its annular side. The upper surface of the sleeve 1 is fitted with a sealing gasket 6. After the tip 7 is installed, the screw 2 and the sleeve 1 are threadedly connected. The hexagonal head 3 is snapped into the upper end of the screw 2. The hexagonal head 3 is snapped into the two arc-shaped blocks 15 fixed on it and the two arc-shaped grooves 17 on the upper end of the screw 2 to ensure the stability of the connection. At this time, the screw 4 is fitted into the hexagonal head 3. The bottom end of the screw 4 is connected and fixed to the threaded groove 16 on the upper end of the screw 2. At this time, the hexagonal head 3 and the screw 2 are fixed. The connection between the sleeve 1 and the screw 2 is provided with a sealing gasket 6 to ensure its airtightness. The whole is designed to be detachable. When a part is damaged, it can be replaced separately without replacing the whole body, which reduces maintenance costs.

[0030] Working principle:

[0031] During installation, the tip 7 is first movably fitted onto the lower end of the sleeve 1. The connecting post 13 and threaded post 12 on the tip 7 extend into the sleeve 1. The tightness of the connection between the sleeve 1 and the tip 7 is ensured by the fitting of the connecting ring 14 and the annular groove 10. At this time, the threaded ring 8 is threaded into the sleeve 1 using an Allen wrench. As the threaded ring 8 moves downward, its lower end will be threaded and fixed with the threaded post 12. At this time, the tip 7 and the sleeve 1 are in a fixed state. By setting the tip 7, when the sleeve 1 is installed in a softer plate or filling material, the tip 7 can play a guiding role, making it easier to pierce the material surface and allowing the sleeve 1 to enter smoothly. This design reduces the external force required during installation and allows the sleeve 1 to follow the set direction. The accurate insertion direction reduces the difficulty of installation and improves installation efficiency. After the tip 7 is installed, the screw 2 is threaded into the sleeve 1. The hexagonal head 3 is snapped into the upper end of the screw 2. The hexagonal head 3 is snapped into the two arc-shaped blocks 15 fixed on it and the two arc-shaped grooves 17 opened at the upper end of the screw 2 to ensure the stability of the connection between the two. At this time, the screw 4 is screwed into the hexagonal head 3. The bottom end of the screw 4 is connected and fixed to the threaded groove 16 opened at the upper end of the screw 2. At this time, the hexagonal head 3 and the screw 2 are fixed. A sealing gasket 6 is set at the connection between the sleeve 1 and the screw 2 to ensure its airtightness. The whole is detachable. When a part is damaged, it can be replaced separately without replacing the whole body, which reduces maintenance costs.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
