Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a heating and ventilation pipe for heating and ventilation engineering, including a pipe body 1. In this application, the pipe body 1 refers to a heating and ventilation pipe. The inner wall of the pipe body 1 is smooth, which can reduce the resistance during fluid transportation and thus improve the transportation efficiency. The pipe body 1 is responsible for transporting gas or liquid. A merging component 2 is set between the pipe bodies 1 to realize the connection and fixation between the pipe bodies 1. A reinforcing component 3 is set on the outer wall of the pipe body 1 to enhance the stability of the connection of the pipe bodies 1.

[0026] like Figures 1-5As shown in the embodiment of this application, the merging component 2 includes a merging sleeve 203, which is located on the outer walls of both ends of the pipe body 1. A locking ring 206 is provided in the middle of the inner wall of the merging sleeve 203, and sealing rings 205 are provided on both sides of the locking ring 206. The sealing rings 205 are located in the circular grooves of the inner wall of the merging sleeve 203. An internal thread is provided between the sealing rings 205 and the locking rings 206, and the internal thread matches the external thread on the outer wall of the pipe body 1. Specifically, when connecting the pipe bodies 1, the two sets of pipe bodies 1 are... The pipe body 1 is inserted into both ends of the merging sleeve 203, and by rotating the merging sleeve 203, the external thread of the pipe body 1 can be connected to the internal thread of the merging sleeve 203. Due to the locking ring 206, the pipe body 1 is limited, controlling its displacement within the merging sleeve 203. This ensures complete connection between the external thread of the pipe body 1 and the internal thread of the merging sleeve 203, preventing excessive displacement of the pipe body 1 within the merging sleeve 203, which would otherwise only partially connect the other pipe body 1 to the internal thread of the merging sleeve 203. This leads to an unstable connection between the pipe body 1 and the merging sleeve 203. The sealing ring 205 is placed in the sealing groove on the inner wall of the merging sleeve 203. The sealing ring 205 is made of aging-resistant and high and low temperature resistant rubber material, which has good elasticity and sealing performance. When connecting the pipe, the sealing ring 205 will be squeezed by the pipe body 1 during the connection process between the pipe body 1 and the merging sleeve 203. As a result, the sealing ring 205 will be tightly attached to the inner wall of the merging sleeve 203. Due to its elasticity, it can fill the gap between the merging sleeve 203 and the pipe body 1, thereby preventing gas or liquid leakage and ensuring the sealing performance of the connection between the pipe body 1 and the merging sleeve 203. It should be noted that when the two ends of the merging sleeve 203 are inserted into the pipe body 1, the thread direction of the external threads of the pipes at both ends should be consistent. If the thread direction of the two ends of the pipe body 1 is opposite, rotating the merging sleeve 203 will cause one end to tighten and the other end to loosen, which will not form an effective seal. Moreover, the consistent thread direction can generate axial pressure during rotation, which enhances the sealing performance with the merging sleeve 203.

[0027] like Figures 1-5As shown in the embodiment of this application, the inner walls of both ends of the merging sleeve 203 are provided with annular grooves 201, and multiple slots 202 are provided on the annular grooves 201. The slots 202 match the locking blocks 303. The two ends of the pipe body 1 are provided with guide fluids 204, which are located on the inner and outer sides of the pipe body 1 respectively. Specifically, the guide fluids 204 have a conical structure, and one of the guide fluids 204 at both ends of the same pipe body 1 is located on its outer wall, and the other is located on its inner wall. During the connection process, the guide fluid 204 on the outer wall of one end of the pipe body 1 will be inserted into the other pipe body 1. Within the guide fluid 204 of the wall, they cooperate with each other. When transporting gas or liquid using pipe body 1, it will enter another pipe body 1 through the guide fluid 204, enabling centralized transport of gas or liquid. It should be noted that when connecting pipe bodies 1, the orientation of the guide fluid 204 should be the same as the flow direction of the gas or liquid. The annular grooves 201 provided at both ends of the merging sleeve 203 are used to cooperate with the reinforcing component 3, thereby further connecting pipe body 1 and merging sleeve 203 and enhancing the stability of the connection between pipe body 1 and merging sleeve 203.

[0028] like Figures 1-5As shown in the embodiment of this application, the reinforcing component 3 includes: a fixing ring 305, which is located on the outer wall of the pipe body 1. Multiple fixing posts 301 are provided on both sides of the fixing ring 305. A fixing rod 302 is provided on the inner wall of each fixing post 301. A push ring 306 is provided at one end of each fixing rod 302. A spring 304 is provided inside the push ring 306. A locking block 303 is provided at one end of each spring 304. The push ring 306 matches the ring groove 201. Specifically, before connecting the pipe body 1, the fixing ring 305 and the push ring 306 are pre-fitted onto the outer wall of the pipe body 1. Both are movably connected to the pipe body 1. Therefore, rotating the pipe body 1 or the merging sleeve 203 will not affect the fixing ring 305 and the push ring 306. After the pipe body 1 and the merging sleeve 203 are connected, the worker pushes the push ring 306. A fixing rod 302 is connected to one side of the push ring 306. The fixing rod 302 is slidably set on the inner wall of the fixing column 301. The fixing column 301 is used to limit the fixing rod 302, and one end of the fixing rod 302 is connected to the fixing ring 305. During the process of pushing the push ring 306 to move to both sides, the push ring 306 will drive the fixing rod 302 along the fixing column. The inner wall of 301 slides, and the push ring 306 can enter the annular groove 201 of the merging sleeve 203 during the translation along the pipe body 1. During the contact between the push ring 306 and the annular groove 201, the locking block 303 will be squeezed by the merging sleeve 203. The side of the locking block 303 facing the merging sleeve 203 is provided with a slope. After being squeezed, the locking block 303 will gradually move towards the inner side of the push ring 306, thereby driving the spring 304 to compress. After the side of the push ring 306 is in complete contact with the annular groove 201, the locking block 303 will be rebounded by the spring 304 and enter the locking groove 202. Since the locking block 303 is facing away from the groove 202, the locking block 303 will be pushed into the groove 202. One side of the annular groove 201 is flat, so after the locking block 303 enters the locking groove 202, the locking groove 202 will limit the locking block 303, thereby improving the stability of the connection between the pipe body 1 and the merging sleeve 203. After the locking block 303 and the locking groove 202 are matched, the fixing rod 302 does not contact the two ends of the inner wall of the fixing column 301. That is to say, the position of the fixing ring 305 can be changed. When installing HVAC pipes, by adjusting the position of the fixing ring 305 and fixing it to the wall or ceiling of the building, the shaking of the pipe body 1 can be limited, and the stability of the connection of the pipe body 1 can be improved.

[0029] The working principle of this utility model is as follows:

[0030] Before connecting the pipe body 1, the fixing ring 305 and the push ring 306 are fitted onto the outer wall of the pipe body 1. Then, the pipe body 1 is inserted into both ends of the merging sleeve 203 and the merging sleeve 203 is rotated. During the rotation of the merging sleeve 203, the pipe body 1 will translate along the axial direction of the merging sleeve 203. Under the action of the external thread of the pipe body 1 and the internal thread of the merging sleeve 203, the initial connection of the pipe body 1 is completed. Then, the push ring 306 is pushed to both sides. The push ring 306 will gradually enter the annular groove 201 of the merging sleeve 203. During the contact between the push ring 306 and the annular groove 201, the locking block 303 will enter the locking groove 202 and be restricted by the locking groove 202, thereby improving the stability of the connection between the pipe body 1 and the merging sleeve 203.

[0031] In summary, this utility model discloses a heating and ventilation (HVAC) pipe for HVAC engineering, including a pipe body 1, a merging assembly 2 disposed between the pipe bodies 1 for connecting and fixing the pipe bodies 1, and a reinforcing assembly 3 disposed on the outer wall of the pipe body 1 to enhance the stability of the connection. This utility model achieves the connection between the pipe bodies 1 through the cooperation of the internal thread of the merging sleeve 203 and the external thread of the pipe body 1. After the pipe body 1 is connected to the merging sleeve 203, the push ring 306 is pushed into the annular groove 201 of the merging sleeve 203, thereby pushing the locking block 303 to the locking groove 202. The locking groove 202 will limit the locking block 303, further improving the stability of the connection between the pipe body 1 and the merging sleeve 203. Furthermore, the fixing ring 305 can cooperate with the wall or ceiling of the building, thereby preventing the pipe body 1 from shaking, reducing the risk of damage to the connection due to pipe instability, and improving the practicality and service life of the HVAC pipe.

[0032] 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 embodiments and their equivalents.
