AI Technical Summary
In existing pipe cap designs, the double thread and double locking mechanism limit the product's aesthetics and cannot meet the market demand for round pipes with a single thread and locking mechanism.
A single-threaded, single-position positioning pipe cap is designed. Through the mating connection of external and internal threads, combined with the structure of the positioning block and sealing gasket, the pipe cylinder and the pipe body are fixed and sealed. The single-threaded, single-position design meets the requirements of aesthetics and positioning.
This design improves the aesthetics of the pipe cap while meeting positioning requirements, thus overcoming the limitations on aesthetics imposed by the double-threaded, double-position design.

Description
Technical Field
[0001] This utility model relates to the field of pipe cap technology, specifically a single-threaded single-position positioning pipe cap. Background Technology
[0002] In the current market, pipe caps require positioning. Specifically, the center of the cap's butterfly joint must align with the marking point on the pipe seal tail, with a lateral deviation within ±2 degrees. Positioning products are typically flat or irregularly shaped pipes, and the design for flat (or irregularly shaped) pipes uses a double-threaded, double-locking mechanism to achieve positioning. However, this double-threaded, double-locking design limits and affects the aesthetics of the pipe cap. Currently, there is a gap in the market for pipe caps with locking and positioning for single-threaded round pipes. Therefore, improvement is needed. Utility Model Content
[0003] The purpose of this utility model is to provide a single-threaded, single-position positioning pipe cap, which solves the problem that the double-threaded, double-position design affects the aesthetics of the pipe cap product.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-threaded single-position positioning pipe cap, comprising a pipe body, an external thread on the top outer surface of the pipe body, a sleeve movably sleeved on the outside of the pipe body, a positioning block inside the sleeve, the positioning block engaging with the pipe body, a flow channel inside the sleeve, an outlet at the top of the sleeve, a cover plate engaged at the top of the sleeve, a connecting sleeve fixedly connected to the inner side of the cover plate, a sealing gasket fixedly connected inside the connecting sleeve, and a sealing mark on the outer surface of the pipe body.
[0005] Preferably, the tube has an internal thread, which engages with the external thread. By designing the engagement between the internal and external threads, the connection between the tube and the tube body can be achieved.
[0006] Preferably, the connecting sleeve is slidably connected to the outlet, and the connecting sleeve is in contact with the surface of the outlet. By designing the connecting sleeve, the outlet can be sealed.
[0007] Preferably, the sealing gasket contacts the outlet, and the sealing gasket is made of rubber. By designing the sealing gasket, the connection between the connecting sleeve and the outlet can be sealed.
[0008] Preferably, the flow channel is connected to the pipe body and communicates with the outlet. The flow channel is designed for the flow and discharge of materials.
[0009] Preferably, the outer side of the cover plate is hinged with a hinge seat, which is fixedly connected to the tube. By designing the hinge seat, the cover plate can rotate relative to the tube.
[0010] Preferably, the outer side of the cover plate is provided with an edge protrusion, which is arc-shaped. The edge protrusion design facilitates the opening and closing of the cover plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This utility model, through the design of external and internal thread engagement, enables the connection and fixation of the tube sleeve and the tube body. With the help of the locking block, it enables the locking engagement of the tube sleeve and the tube body. Through the single thread and single locking form, a single clamping thread and single locking positioning tube cap can be formed to meet the current market demand for improved product aesthetics.

[0017] 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.
[0018] Please see Figure 1 , Figure 2 , Figure 3 A single-threaded single-position positioning pipe cap includes a pipe body 1. The top outer surface of the pipe body 1 is provided with an external thread 2. The inside of the pipe sleeve 3 is provided with an internal thread 4. The internal thread 4 and the external thread 2 are threadedly engaged. By designing the engagement between the internal thread 4 and the external thread 2, the connection between the pipe sleeve 3 and the pipe body 1 can be realized. The pipe sleeve 3 is movably sleeved on the outside of the pipe body 1. The inside of the pipe sleeve 3 is provided with a positioning block 5, which is engaged with the pipe body 1. The inside of the pipe sleeve 3 is provided with a flow channel 6, which is connected to the pipe body 1 and communicates with an outlet 7. The flow channel 6 is designed for the flow and discharge of materials.
[0019] Please see Figure 1 , Figure 2 , Figure 3 The top of the tube 3 is provided with an outlet 7. A cover plate 8 is snapped onto the top of the tube 3. A connecting sleeve 9 is fixedly connected to the inner side of the cover plate 8. The connecting sleeve 9 is slidably connected to the outlet 7. The surface of the connecting sleeve 9 is in contact with the surface of the outlet 7. By designing the connecting sleeve 9, the outlet 7 can be sealed. A sealing gasket 10 is fixedly connected inside the connecting sleeve 9. The sealing gasket 10 is in contact with the outlet 7. The sealing gasket 10 is made of rubber. By designing the sealing gasket 10, the connection between the connecting sleeve 9 and the outlet 7 can be sealed.
[0020] Please see Figure 1 , Figure 2 , Figure 3 The outer side of the cover plate 8 is provided with an edge protrusion 11, which is arc-shaped. The edge protrusion 11 is designed to facilitate the opening and closing of the cover plate 8. The outer side of the cover plate 8 is hinged with a hinge seat 12, which is fixedly connected to the tube 3. The hinge seat 12 is designed to allow the cover plate 8 to rotate relative to the tube 3. The outer surface of the tube body 1 is provided with a sealing mark 13.
[0021] The specific implementation process of this utility model is as follows: Through the threaded engagement of the external thread 2 and the internal thread 4, the tube 3 and the tube body 1 can be connected and fixed. With the assistance of the locking block 5, the tube 3 and the tube body 1 can be locked together. During use, rotating the edge protrusion 11 allows the cover plate 8 to rotate along the hinge seat 12. At this time, the connecting sleeve 9 can slide along the outlet 7 and separate from the outlet 7, allowing the material inside the tube body 1 to be removed. This single-threaded, single-locking design forms a single-clamp threaded, single-locking positioning tube cap to meet the current market demand for improved product aesthetics.
