Description

Technical Field

[0001] This utility model relates to the technical field of tee elbows, specifically a quick-install tee elbow. Background Technology

[0002] A tee elbow is a special pipe connection element that combines the functions of a tee and an elbow. It can both split or merge pipes and change the flow direction. By setting up a tee elbow, multiple pipes or equipment can be connected, allowing fluid to flow between different pipes or equipment. It is widely used.

[0003] As disclosed in announcement number CN218408981U, a tee elbow with improved service life is provided, including a right-angle tee elbow. A first flange is provided at the top of the right-angle tee elbow, and a second flange is provided at one end. A threaded groove is formed on the inner wall of the other end of the right-angle tee elbow. A sealing disc is provided on one side of the right-angle tee elbow, and a threaded sleeve is located at the center of the outer wall of one side of the sealing disc. A rotating rod is located at the center of the inner side of the outer wall of one side of the sealing disc, near the threaded sleeve. This tee elbow with improved service life, through the storage and guiding action of the flow-guiding buffer disc inside the right-angle tee elbow, allows granular material to directly contact the flow-guiding buffer disc. A portion of the granular material is stored in the storage tank, and when the granular material falls, it rubs more against the stored granular material, greatly reducing the friction between the material and the pipe wall, thereby improving the service life of the right-angle tee elbow and significantly saving costs.

[0004] However, in the existing technology, most tee elbows require bolts and external installation tools to connect to external pipes, or directly set threads at the tee interface and rotate the tee pipe to connect to the external connecting pipe with matching threads. This affects the accurate alignment between the tee elbow body and the external pipe, making the installation operation inconvenient. During long-term use and under the pressure generated by the internal fluid, it is easy to loosen and cause leakage. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we have proposed a quick-install tee elbow. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-installation tee elbow to solve the problems mentioned in the background art, where tee elbows mostly require bolts and external installation tools to connect to external pipes, or directly set threads at the tee interface and rotate the tee pipe to connect to the external connecting pipe with matching threads. This affects the accurate alignment between the tee elbow body and the external pipe, making installation and operation inconvenient. In the long-term use and under the pressure generated by the internal fluid, it is easy to loosen and cause leakage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-install tee elbow, comprising a tee elbow body and an installation connector cap for connection;

[0008] Also includes:

[0009] A sealing ring is disposed inside the mounting connector cap and fits between the connector plate and the external pipe.

[0010] An anti-detachment mechanism is provided on both sides of the opening of the tee elbow body, and the anti-detachment mechanism is used to lock the installation connector cap and the tee elbow body.

[0011] Preferably, the opening of the tee elbow body is integrally connected to a connecting plate, and the inner side of the connecting plate is provided with a fixing groove for limiting the position at equal angles.

[0012] Preferably, the inner side of the mounting connector is provided with threads, and the mounting connector is threadedly connected to the external connecting pipe.

[0013] Preferably, the mounting cap is rotatably connected to the opening of the tee elbow body, and the inner side of the mounting cap is fitted against the side of the connecting plate.

[0014] Preferably, the anti-detachment mechanism includes a fixed plate fixedly connected to the edge of the tee elbow body near the mounting cap, a movable connecting rod for positioning, a spring sleeved on the outer surface of the movable connecting rod, a movable connecting block fixedly connected to the middle of the movable connecting rod, and a movable pull plate fixedly connected to the end of the movable connecting rod away from the mounting cap.

[0015] Preferably, the movable connecting rod and the mounting connecting cap form a sliding structure, and the movable connecting rod is inserted into the fixing groove at the corresponding position.

[0016] Preferably, the movable connecting rod drives the movable connecting block to form a sliding structure with the fixed plate, and the movable connecting rod is disposed through the middle of the fixed plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This quick-install tee elbow connects to the external pipe by rotating the connecting cap at the opening of the tee elbow body. This allows for quick and convenient connection between the tee elbow body and the external pipe without the need for bolts or external installation tools. This ensures better fit and alignment between the tee elbow body and the external connecting pipe. Combined with the anti-detachment mechanism, it facilitates locking and limiting the connection between the tee elbow body and the connecting cap, preventing the connecting cap from rotating on its own, improving the stability of the connection during long-term use, and ensuring the sealing effect of the connection.

[0018] 1. It is equipped with a mounting cap and a sealing ring. The mounting cap rotates between itself and the tee elbow body, and the mounting cap is threaded to the external pipe. This facilitates quick alignment and installation between the tee elbow body and the external pipe. Combined with the sealing ring, it improves the sealing effect at the connection.

[0019] 2. An anti-detachment mechanism is provided, which includes a fixed plate, a movable connecting rod, a spring, a movable connecting block, and a movable pull plate. The anti-detachment mechanism can lock and limit the connection between the installation connector and the tee elbow body, thereby improving the stability of the connection.

[0027] 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.

[0028] Please see Figures 1-7 The present invention provides the following technical solution.

[0029] Example 1: To address the problem that existing tee elbows mostly require bolts and external installation tools to connect to external pipes, or directly use threads at the tee joint to rotate the tee pipe to connect to an external threaded connecting pipe, which affects the precise alignment between the tee elbow body 1 and the external pipe and makes installation inconvenient, this example provides a quick-install tee elbow, comprising a tee elbow body 1, a connecting plate 2, an installation connecting cap 4, and a sealing ring 5. Figure 1 , Figure 2 and Figure 4 As shown, a connecting plate 2 is integrally formed at the interface of the tee elbow body 1. A connecting cap 4 is fitted onto the interface on the outside of the tee elbow body 1. The inner side of the connecting cap 4 is threaded, and a sealing ring 5 is provided on the outer side of the connecting plate 2. When connecting the tee elbow body 1 to an external pipe, the threaded external pipe is placed on the outside of the connecting plate 2. At the same time, the sealing ring 5 is fitted between the connecting plate 2 and the external pipe. The sealing effect at the connection is improved by the sealing ring 5. Then, the connecting cap 4 is rotated, and the connecting cap 4 rotates with the tee elbow body 1. The connecting cap 4 is threadedly connected to the external pipe, which facilitates quick docking and installation between the tee elbow body 1 and the external pipe. Dirt is fixed with bolts, and the alignment between the tee elbow body 1 and the external pipe is easy during installation.

[0030] Example 2: Existing quick-install tee elbows are prone to loosening and leakage during long-term use and under the pressure of internal fluids. Therefore, an anti-detachment mechanism 6 is provided to lock the mounting cap 4 and the tee elbow body 1. The anti-detachment mechanism 6 includes a fixed plate 7 fixedly connected to the edge of the mounting cap 4 near the tee elbow body 1, a movable connecting rod 8 for positioning, a spring 9 sleeved on the outer surface of the movable connecting rod 8, a movable connecting block 10 fixedly connected to the middle of the movable connecting rod 8, and a movable pull plate 11 fixedly connected to the end of the movable connecting rod 8 away from the mounting cap 4. The movable connecting rod 8 and the mounting cap 4 form a sliding structure, and the movable connecting rod 8 is inserted into the fixed groove 3 at the corresponding position. The movable connecting rod 8 drives the movable connecting block 10 to form a sliding structure with the fixed plate 7, and the movable connecting rod 8 is inserted through the middle of the fixed plate 7. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, when the mounting connector 4 is rotated to connect with the external connecting pipe, the movable pull plate 11 is pulled, causing the movable connecting rod 8 to slide between the movable pull plate 11 and the fixed plate 7. At this time, the movable connecting rod 8 causes the movable connecting block 10 to slide between the movable connecting rod 8 and the fixed plate 7, improving the stability of the movable connecting rod 8 during movement. While the movable connecting rod 8 slides between itself and the mounting connector 4, it compresses the spring 9, causing the spring 9 to undergo elastic deformation. After the mounting connector 4 is threadedly connected to the external connecting pipe, the movable pull plate 11 is released directly. At this time, the spring 9 returns to its elastic deformation, causing the movable connecting rod 8 to slide between itself and the mounting connector 4, so that the movable connecting rod 8 is inserted into the fixed groove 3 at the corresponding position. This facilitates locking between the mounting connector 4 and the tee elbow body 1, preventing the mounting connector 4 from rotating on its own, improving the stability of the connection between the mounting connector 4 and the external pipe, and preventing loosening during long-term use.

[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.
