Description

Technical Field

[0001] The utility model relates to the technical field of building HVAC, in particular to a building HVAC pipeline connection structure. Background Art

[0002] HVAC is an integral part of a building, including heating, ventilation, and air conditioning. It is also a training area for people engaged in the fields of building environment control, building energy conservation, and intelligent technology of building facilities. It has public facilities systems such as air conditioning, heating, ventilation, building water supply and drainage, and gas supply. When HVAC pipes need to be repaired, they are often difficult to disassemble. Therefore, the convenient design of the connection structure has become a blessing for maintenance personnel.

[0003] Patent document CN218267762U discloses a building HVAC pipe connector that is easy to disassemble and install, relating to the field of pipe connection technology. The utility model includes a HVAC pipe connector, a HVAC connecting pipe, a control valve, a connecting pipe locking portion, and a pressure gauge. The HVAC pipe connector is connected to HVAC connecting pipes on both sides, a valve control chamber is welded to the top of the HVAC pipe connector, a control valve is connected to the upper side of the valve control chamber, connecting pipe locking portions are fixed to both ends of the HVAC pipe connector, and a pressure gauge is connected to the end of the HVAC connecting pipe. The utility model solves the problems of existing building HVAC pipe connectors that are inconvenient to install and replace, time-consuming and labor-intensive, and inconvenient to detect when leaks occur, through the configuration and use of a movable handle locking and clamping structure, a ventilation control valve, and a detection pressure gauge.

[0004] However, in the above-mentioned connection structure, the locking handle and the connecting pipe limiter are connected through various components. When force is applied to the locking handle, the connecting pipe limiter and the connecting pipe clamp interface cannot be aligned because the force is applied in different directions, resulting in the connecting pipe limiter and the connecting pipe clamp interface often hitting the wall, thereby increasing the difficulty of disassembly and improving the time efficiency of maintenance. In addition, when multiple HVAC connecting pipes are spliced ​​together, the impact of gas or liquid during use will cause the HVAC ducts to shake, which will cause the connecting pipe limiter to detach from the connecting pipe clamp interface, affecting the sealing of the pipeline, and thus increasing the maintenance cost of the pipeline. Summary of the Invention

[0005] The utility model overcomes the deficiencies of the prior art and provides a building HVAC pipe connection structure.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a building HVAC pipe connection structure, including a HVAC pipe connection part installed between two adjacent first HVAC pipes and a second HVAC pipe, both sides of the outer surface of the HVAC pipe connection part are embedded with connecting blocks, both sides of the top of the connecting block are hinged with pressure plates, the bottom of the connecting block is fixedly installed with a clamping block, dampers are fixedly installed on both sides of the clamping block, the outer surface of the damper is wrapped with a spring, and a movable plate is fixedly installed on one side of the spring; the outer surfaces of the first HVAC pipe and the second HVAC pipe are provided with clamping grooves, and both sides of the outer surface of the HVAC pipe connection part are provided with mounting holes, the mounting holes correspond to the positions of the clamping grooves and together form a cavity matching the shape of the pressure plate.

[0007] Working principle: The staff applies inward pressure to the pressure plate, and then the pressure plate applies inward pressure to the movable plate, and then the movable plate applies pressure to the spring, prompting the spring to drive the damper to contract inward, and then the staff applies downward force to the connecting block, and then the connecting block applies downward force to the card block, prompting the card block to be inserted into the card slot, and then the force applied to the pressure plate is stopped, and then the spring pushes the movable plate under its own elastic action, so that the movable plate rests on the inner wall of the pressure plate, and the outer side of the lower part of the pressure plate rests on the inner wall of the card slot, so that the mutual splicing of the HVAC pipes is more stable, and it is easy to disassemble during maintenance, reducing labor costs, and then when the first HVAC pipe vibrates during operation, thereby colliding with the second HVAC pipe, the spring can effectively slow down the vibration of the first HVAC pipe, thereby having a shock-absorbing effect and improving the practicality of the device.

[0008] Furthermore, a sealing sleeve is fixedly installed on the inner wall of the HVAC pipe connecting part.

[0009] Furthermore, a pressure gauge is embedded and connected to the bottom end of the second HVAC pipe, a control switch is fixedly installed on the bottom of the pressure gauge, and a ventilation pipe is fixedly installed on the bottom of the control switch.

[0010] Furthermore, a valve control cavity is welded on the outer surface of the HVAC pipe connection part, a valve is connected to the top of the valve control cavity, a ventilation control cavity is provided inside the HVAC pipe connection part, and a control panel extending into the ventilation control cavity is provided at the lower part of the valve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model uses a combination of a pressure plate, a spring, a damper, a connecting block, a movable plate and a clamping block, so that the mutual splicing of multiple HVAC pipes is more stable and firm, thereby improving the installation effect of the pipes. At the same time, the disassembly of the HVAC pipes is also more convenient, reducing the time and labor costs of maintenance personnel. The combination of the spring and the damper enables the clamping block to have a shock-absorbing effect on the first HVAC pipe and the second HVAC pipe, further improving the practicality of the device.

[0013] The utility model uses a pressure gauge and a sealing sleeve in combination. The sealing sleeve can play a shock-absorbing effect when slowing down the collision of the first HVAC pipe on the HVAC pipe connection part, while also ensuring the sealing effect of the HVAC pipe connection, thereby improving the practicality of the device, and can judge whether the connection between the two pipes is leaking based on the data of the pressure gauge, making the maintenance process simpler and the effect more practical.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] See also Figures 1-4 , an embodiment provided by the utility model

[0023] A building HVAC pipe connection structure includes a HVAC pipe connection part 3 installed between two adjacent first HVAC pipes 1 and second HVAC pipes 2, and both sides of the outer surface of the HVAC pipe connection part 3 are engaged with connecting blocks 4, and both sides of the top of the connecting block 4 are hinged with pressure plates 5, and the bottom of the connecting block 4 is fixedly installed with a clamping block 6, and dampers 7 are fixedly installed on both sides of the clamping block 6. The outer surface of the damper 7 is wrapped with a spring 8, and a movable plate 9 is fixedly installed on one side of the spring 8; the outer surfaces of the first HVAC pipe 1 and the second HVAC pipe 2 are provided with a clamping groove 16, and both sides of the outer surface of the HVAC pipe connection part 3 are provided with a mounting hole 17, and the mounting hole 17 corresponds to the position of the clamping groove 16 and together form a cavity matching the shape of the pressure plate 5, and the outer surface of the pressure plate 5 is engaged with the mounting hole 17.

[0024] The staff applies inward pressure to the pressure plate 5, and then the pressure plate 5 applies inward pressure to the movable plate 9, and then the movable plate 9 applies pressure to the spring 8, prompting the spring 8 to drive the damper 7 to retract inward, and then the staff applies downward force to the connecting block 4, and then the connecting block 4 applies downward force to the card block 6, prompting the card block 6 to be inserted into the card slot 16, and then stops applying force to the pressure plate 5, and then the spring 8 pushes the movable plate 9 under its own elastic action, so that the movable plate 9 rests on the inner wall of the pressure plate 5, and the outer side of the lower part of the pressure plate 5 rests on the inner wall of the card slot 16, thereby making the mutual splicing of the HVAC pipes more stable, and easy to disassemble during maintenance, reducing labor costs, and then when the first HVAC pipe 1 vibrates during operation, thereby colliding with the second HVAC pipe 2, the spring 8 can well slow down the vibration of the first HVAC pipe 1, thereby having a shock absorption effect and improving the practicality of the device.

[0025] See also Figure 1 、 2 and Figure 5 , an embodiment provided by the utility model:

[0026] Further, such as Figure 2 As shown, a sealing sleeve 10 is fixedly installed on the inner wall of the HVAC pipe connecting part 3.

[0027] Furthermore, a pressure gauge 11 is embedded and connected to the bottom end of the second HVAC pipe 2 , a control switch 12 is fixedly installed on the bottom of the pressure gauge 11 , and a ventilation pipe 13 is fixedly installed on the bottom of the control switch 12 .

[0028] The staff splices and fixes the first HVAC pipe 1 and the second HVAC pipe 2, and then combines the HVAC pipe connecting part 3 with them to fix them. The inner wall of the sealing sleeve 10 fits tightly with the connection between the first HVAC pipe 1 and the second HVAC pipe 2, which can effectively prevent gas leakage. Then, by observing the value of the pressure gauge 11, it is determined whether there is a gas leak, and thus whether the HVAC pipe connecting part 3 is firmly connected, which makes it easier to find the problem and makes the maintenance process more convenient and faster.

[0029] Furthermore, a valve control cavity 14 is welded to the outer surface of the HVAC pipe connecting part 3, a valve 15 is connected to the top of the valve control cavity 14, a ventilation control cavity is provided inside the HVAC pipe connecting part 3, and a control panel extending into the ventilation control cavity is provided at the lower part of the valve 15.

[0030] By observing the value of the pressure gauge 11, it is determined whether there is a leak. If a certain section of the HVAC pipe is found to have a leak, the valves 15 on both sides of the HVAC pipe are closed and the pipe in the middle is replaced. After the replacement is completed, the valves 15 on both sides are opened.

[0031] Working principle: the staff moves the pressing plate 5 inward, and then the pressing plate 5 prompts the movable plate 9 to move inward, and then the movable plate 9 drives the spring 8 to contract inward along the damper 7, and then the staff moves the connecting block 4 downward, and then the connecting block 4 drives the card block 6 to move downward, prompting the card block 6 to be inserted into the card slot 16, and then puts down the pressing plate 5, and then the spring 8 pushes the movable plate 9 under its own elastic action, so that the movable plate 9 rests on the inner wall of the pressing plate 5, and the outer side of the lower part of the pressing plate 5 rests on the inner wall of the card slot 16, thereby increasing the mutual splicing of the HVAC pipes to be more stable, and then, it is easy to disassemble during maintenance, shortening the working time of the staff, and then when the first HVAC pipe 1 is in operation When the second HVAC pipe 2 is in operation, it will vibrate and collide with the second HVAC pipe 2. At this time, the spring 8 can effectively slow down the vibration of the first HVAC pipe 1, thereby having a shock-absorbing effect. In addition, the staff splices the first HVAC pipe 1 and the second HVAC pipe 2, and then fixes them with the HVAC pipe connecting part 3 to make them stable. The inner wall of the sealing sleeve 10 fits tightly with the connection between the first HVAC pipe 1 and the second HVAC pipe 2 to prevent gas leakage. Then, by checking the value of the pressure gauge 11, it can be determined whether there is a gas leak, thereby determining whether the connection of the HVAC pipe connecting part 3 is stable, which makes it convenient to check pipeline problems, makes the maintenance process simpler, and reduces labor costs.
