Technical Field

[0001] The utility model belongs to the technical field of detection devices, and particularly relates to a detection device for the connection tightness of rigid polyvinyl chloride pipes for water supply. Background Art

[0002] A pipe is a material with a tubular structure as a pipe fitting. As is well known, polyvinyl chloride is a thermoplastic resin polymerized from vinyl chloride under the action of an initiator and is a homopolymer of vinyl chloride. With the rapid development of the domestic construction industry and infrastructure construction, the demand for pipes in the infrastructure industry has increased rapidly. Rigid polyvinyl chloride pipes are usually used for water transportation. The requirements for the tightness of water circulation and transportation are very strict, especially the tightness at the pipe joints is particularly important. If the detection is improper, it is very easy to cause water seepage during water transportation.

[0003] Most of the existing airtightness detection devices detect the tightness of pipes by inflating a single pipe into the pipe, and cannot detect multiple pipes synchronously, thus affecting the overall efficiency of detection. Therefore, improvements are now made to the detection device for the connection tightness of rigid polyvinyl chloride pipes for water supply. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a detection device for the connection tightness of rigid polyvinyl chloride pipes for water supply. Through the detection component, the tightness of multiple pipes can be quickly detected, which is convenient for the subsequent use of the pipes, so as to solve the problems raised in the above-mentioned background art.

[0005] To achieve the above object, the utility model provides a detection device for the connection tightness of rigid polyvinyl chloride pipes for water supply, including a support frame. A support plate is provided at the top of the support frame, a detection component is provided at the top of the support plate, and a placement component is provided at the bottom of the detection component;

[0006] The detection component includes a mounting frame fixedly installed on the top of the support plate. Two cylinders are fixedly sleeved on the top of the mounting frame. The output shafts of the two cylinders are fixedly connected with a connecting plate. A plurality of air inlets are provided at the bottom of the connecting plate. A telescopic tube is fixedly sleeved at the center of the connecting plate. The telescopic tube penetrates through the outside of one side of the mounting frame and is fixedly sleeved with a pressure gauge. An air pump is connected to the end of the telescopic tube.

[0007] Preferably, the placement component includes two mounting blocks fixedly installed inside the mounting frame. The two ends of the top of the mounting block are provided with telescopic rods.

[0011] Preferably, a support pad is arranged at the bottom of the support frame, and a damping block is installed inside the support pad.

[0012] The water supply hard polyvinyl chloride pipe connection tightness detection device proposed by the present utility model can bring the following beneficial effects:

[0013] Gas is applied to the inside of the telescopic pipe through an air pump, so that the gas reaches the inside of the connecting plate through the telescopic pipe and is finally input into the pipe through the air inlet at the bottom of the connecting plate.

Detailed implementation manner

[0021] As Figures 1 to 4 shown, an embodiment of the present utility model provides a detection device for the connection tightness of rigid polyvinyl chloride pipes for water supply, including a support frame 2. A support plate 3 is provided at the top of the support frame 2, a detection assembly is provided at the top of the support plate 3, and a placement assembly is provided at the bottom of the detection assembly;

[0022] The detection assembly includes a mounting frame 4 fixedly installed on the top of the support plate 3. Two cylinders 5 are fixedly sleeved on the top of the mounting frame 4. The output shafts of the two cylinders 5 are fixedly connected to a connecting plate 14. A plurality of air inlets 19 are provided at the bottom of the connecting plate 14. A telescopic tube 7 is fixedly sleeved at the center of the connecting plate 14. The telescopic tube 7 penetrates through the outside of one side of the mounting frame 4 and is fixedly sleeved with a pressure gauge 6. The end of the telescopic tube 7 is connected to an air pump 15. Observe the pressure gauge 6. When the air pressure is lower than the pressure value preset by the pressure gauge 6, it indicates that the tightness of this detection is poor. On the contrary, when it is not lower than the standard set value, it indicates that the tightness of the pipe is okay, thus completing the detection of the pipe.

[0023] As Figure 4 shown, the placement assembly includes two mounting blocks 8 fixedly installed inside the mounting frame 4. At both ends of the top of the mounting block 8, telescopic rods 9 are installed. A damping spring 13 is fixedly sleeved on the outside of the telescopic rod 9. The top of the telescopic rod 9 is installed with a placement plate 12. A placement groove 11 corresponding to the plurality of air inlets 19 is provided at the top of the placement plate 12. A limit post 10 is provided at the center of the inside of the placement groove 11, so that the limit post 10 inside the placement groove 11 plays a role in limiting the pipe, preventing the pipe from tilting during the detection and affecting the fixation between the air inlet 19 and the top end of the pipe. The inside of the connecting plate 14 is of a hollow structure, and the connecting plate 14 is communicated with the air inlet 19, facilitating the transmission of gas into the pipe through the air inlet 19 for detection.

[0024] As Figure 3 shown, limit blocks 18 are installed on both sides of the connecting plate 14. A limit groove 17 is opened on the outside of one side of the limit block 18 close to the mounting frame 4. The limit block 18 is slidably connected with the limit groove 17. During the movement, the connecting plate 14 slides through the limit block 18 and the limit groove 17, thereby increasing the stability of the connecting plate 14 when moving downward.

[0025] As Figure 1As shown in the figure, a controller 16 is installed outside the support plate 3. The controller 16 is electrically connected to the cylinder 5. The operation of the cylinder 5 can be realized through the controller 16, which is convenient for the operator to detect the pipe.

[0026] As Figure 1 shown in the figure, a support pad 1 is provided at the bottom of the support frame 2, and a vibration damping block is installed inside the support pad 1. It can play a role in damping the entire device, offset the vibration generated during the operation of the device, and avoid affecting the stability of the pipe during fixation when vibrating.

[0027] Working principle:

[0028] Before use, this device needs to be placed on a flat ground. Then the operator externally fixes and slews two pipes to be detected together. After that, the multiple slewed pipes are sleeved inside the multiple placement grooves 11 on the top of the placement plate 12, so that the limit posts 10 inside the placement grooves 11 play a role in limiting the pipes, preventing the pipes from tilting during detection. Then, the external power supply is connected, and the controller 16 is used to make the output shaft of the cylinder 5 drive the connecting plate 14 to move downward. During the movement, the connecting plate 14 slides through the limit block 18 and the limit groove 17, thereby increasing the stability of the connecting plate 14 during downward movement. When the air inlet 19 at the bottom of the connecting plate 14 contacts the top of the pipe placed in the placement groove 11, the telescopic rod 9 and the damping spring 13 at the bottom of the placement plate 12 interact to damp the pipe at the top of the placement groove 11, preventing the connecting plate 14 from damaging the top of the pipe during downward movement. At this time, the cylinder 5 stops working. Then, a gas is applied to the inside of the telescopic tube 7 through the air pump 15, so that the gas reaches the inside of the connecting plate 14 through the telescopic tube 7 and is finally delivered to the inside of the pipe through the air inlet 19 at the bottom of the connecting plate 14. At this time, only need to observe the pressure gauge 6 on one side of the telescopic tube 7. When the air pressure is lower than the pressure value preset by the pressure gauge 6, it indicates that the tightness of this detection is poor. On the contrary, when it is not lower than the standard set value, it indicates that the tightness of the pipe is good, thus completing the detection of the pipe.

[0029] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other. The key point of each embodiment is to illustrate the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.

[0030] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
