Description

Technical Field

[0001] The utility model relates to the field of bayonet fixing, in particular to a convenient spring type bayonet fixing device. Background Art

[0002] At present, non-metallic pipe fittings are increasingly used due to their advantages of good corrosion resistance, good sealing, low price, convenient docking, and easy installation. However, when the pipe fittings and connectors are connected by insertion, the pipe fittings and connectors may slip due to changes in ambient temperature and fluid pressure in the pipe fittings, thus interrupting the pipeline and causing fluid overflow in the pipe fittings, which seriously affects the safety of fluid transportation and causes waste of resources.

[0003] According to the patent application number CN200720048923.X, a bayonet-type pipe fixing device is provided, which includes a pipe and a connector. A convex body is provided on the outer wall of the pipe, and a groove is provided on the inner wall of the connector. After the pipe is inserted into the connector, the convex body on the pipe is engaged with the groove in the connector, which ensures the stable connection between the pipe and the connector, ensures the smooth flow of the pipeline, and effectively avoids the slippage between the pipe and the connector. It has the advantages of simple structure, convenient use, safety and reliability, and is suitable for the connection of various pipes, especially for the connection of pipes made of non-metallic materials.

[0004] There are still some shortcomings in this patent application. This patent does not perform airtight treatment on the pipe joints. When high-pressure water passes through the joints, water will seep out from the notched grooves. In addition, the pipe joints are easily damaged due to long-term impact of water flow. The convex bodies and grooves of the pipes are bound to the pipes, making maintenance difficult, resulting in a high discard rate of the pipes, which greatly wastes resources. Therefore, a convenient spring-type bayonet fixing device is needed to solve this problem. Utility Model Content

[0021] In the present embodiment, the pipe fitting 2 is inserted into the pipe hole 3 and engaged with the sealing ring 41 to achieve the docking of the pipeline, thereby ensuring the sealing of the connection of the pipe fitting 2. The latex material of the sealing ring 41 greatly improves the sealing performance and ensures that water will not leak out. A buffer spring 311 is provided on one side of the sealing ring 41 to ensure that the pipe fitting 2 has a buffer effect when being pulled during use, and will not become loose due to long-term pulling, thereby further improving the reliability of the seal.

[0022] Example 2

[0023] See also Figure 4 to Figure 5 Description of Example 2. This embodiment further describes Example 1. A pipe locking assembly 5 is provided at the pipe mouth of the pipe hole 3. The pipe locking assembly 5 includes a rotating screw 51. The rotating screw 51 is provided with a thread 511. The rotating screw 51 is engaged with a sliding rod 52. The sliding rod 52 is provided with a spiral hole 521. The sliding rod 52 is engaged with a main sliding groove 12. The main sliding groove 12 is provided with a spring 121. The spring 121 is connected to the sliding rod 52. A sliding sub-rod 53 is provided under the rotating screw 51. The sliding sub-rod 53 is engaged with the sliding sub-groove 13. One side of the sliding sub-rod 53 is connected to an arc-shaped locking rod 54.

[0024] In this embodiment, rotating the rotating screw 51 causes the rotating screw 51 to move in the spiral hole 521 of the sliding rod 52, thereby acting on the sliding sub-rod 53, causing the sliding sub-rod 53 to move in the sliding sub-groove 13, driving the arc-shaped locking rod 54 to move and squeeze the pipe fitting 2, thereby locking and fixing the pipe fitting 2 from the top and bottom. The arc-shaped design of the arc-shaped locking rod 54 increases the friction with the pipe fitting 2, making the locking more stable. When the pipe fitting 2 is pulled, the spring 121 on one side of the sliding rod 52 can play a buffering role.

[0025] In specific applications, firstly, the pipe fitting 2 is inserted into the pipe hole 3 and engaged with the sealing ring 41 to achieve the butt joint of the pipeline, so as to ensure the sealing performance of the connection of the pipe fitting 2. The latex material of the sealing ring 41 greatly improves the sealing performance and ensures that the water flow will not seep out. After the pipe fitting 2 is butt jointed, the rotating screw 51 is turned to make the rotating screw 51 move in the spiral hole 521 of the sliding rod 52, and then act on the sliding auxiliary rod 53 to make the sliding auxiliary rod 53 move in the sliding auxiliary groove 13, driving the arc locking rod 54 to move and squeeze the pipe fitting 2, so as to lock the pipe. The pipe 2 is locked and fixed from the upper and lower sides. The arc design of the arc locking rod 54 increases the friction with the pipe 2, making the locking more stable. When the pipe 2 is pulled during use, the buffer spring 311 on one side of the sealing ring 41 can play a buffering effect, and the pipe 2 and the sealing ring 41 will not loosen or fall off due to long-term pulling, further improving the reliability of the seal. The spring 121 on one side of the sliding rod 52 can also play a buffering role, greatly improving the sealing performance of the device and the fixing performance of the pipe 2.
