Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipes, in particular to a plastic pipe quick installation structure. Background Art

[0002] The length of existing water pipes is fixed. During the installation process, two water pipes are connected together. The existing connection methods mainly include bonding and welding. When the water pipe is damaged, it is not easy for the staff to replace or disassemble it.

[0003] Publication No. CN219282715U discloses a plastic tube that can be quickly installed, including a first plastic tube and a second plastic tube, wherein an arc-shaped plate is symmetrically fixedly installed at the bottom of the first plastic tube, and the outer walls of the two arc-shaped plates are provided with threads, and a sealing ring is fixedly installed at the bottom of the first plastic tube, and the inner wall of the arc-shaped plate is set against the outer wall of the second plastic tube, and the outer wall of the first plastic tube is slidably connected with a fastening ring; this plastic tube that can be quickly installed is installed by installing an arc-shaped plate at the bottom of the first plastic tube, installing a fastening ring on the outer wall of the first plastic tube, inserting the second plastic tube between the two arc-shaped plates, and abutting against the bottom of the sealing ring. This design is convenient for the staff to connect the two plastic tubes, and can prevent the gas in the plastic tube from overflowing. By installing an anti-reversal component at the bottom of the arc-shaped plate, the staff can prevent the fastening ring from rotating during use. However, the patent still has the following problems in actual use:

[0004] The above device needs to rotate the fastening ring during installation, and still needs to use the threaded structure.

The connection component 2 further includes a docking sleeve 202 fixedly connected to the end of the second pipe body 102, and the docking sleeve 202 and the connection sleeve 201 overlap;

[0030] Wherein, a disc 203 is fixedly connected to the inside of the connection sleeve 201 and the side of the docking sleeve 202 close to the connection sleeve 201;

[0031] Wherein, barbs 204 and trapezoidal strips 205 are symmetrically and fixedly connected to the outside of the disc 203,

[0032] Wherein, a limiting component 3 is symmetrically arranged on the outside of the docking sleeve 202.

[0033] The trapezoidal strip 205 is located on the side of the barb 204. The inclined surface of the trapezoidal strip 205 is close to the farther barb 204, and there is a gap between the trapezoidal strip 205 and the farther barb 204; the barb 204 can pass through the gap,

[0034] The barbs 204 on different discs 203 are snap-connected with the trapezoidal strips 205. Sealing rings 206 are fixedly connected to the sides of the discs 203 close to each other. A communication hole 207 is opened inside the disc 203 close to the first pipe body 101, and a docking pipe 208 is fixedly connected to the inside of the disc 203 close to the second pipe body 102. The docking pipe 208 is inserted into the communication hole 207; the docking pipe 208 is inserted into the communication hole 207 and fits against the inner wall of the communication hole 207, which can serve as the first anti-leakage structure, and the close contact of the two sealing rings 206 can serve as the second anti-leakage structure.

[0035] The symmetric centers of the two trapezoidal strips 205 and the limiting component 3 are both the center of the disc 203. The limiting component 3 includes a part shell 301 fixedly connected to the outside of the docking sleeve 202. A spring rod 302 is arranged inside the part shell 301, and first pads 303 and second pads 304 are fixedly connected to both ends of the spring rod 302.

[0036] The first backing plate 303 is fixedly connected to the inner side of the part housing 301. A buckle block 305 is fixedly connected to the outer side of the second backing plate 304. A displacement groove 306 is formed in the top surface of the second backing plate 304. A sliding block 307 is slidably connected inside the displacement groove 306. The buckle block 305 is snap-connected to a limiting block 308, and the limiting block 308 is fixedly connected to the connecting sleeve 201. Both ends of the displacement groove 306 are respectively directly below the two ends of the straight groove section of the unlocking groove 315 close to the limiting block 308, and the buckle block 305 is slidably connected to the part housing 301.

[0037] A vertical rod 309 is fixedly connected to the top of the sliding block 307. A first spring 310 is sleeved outside the vertical rod 309. The top end of the vertical rod 309 is slidably connected to a sleeve rod 311. The sleeve rod 311 penetrates through the part housing 301. A support plate 312 is fixedly connected to the side of the part housing 301. A square clamping block 313 is fixedly connected to the top of the other end of the support plate 312. The first spring 310 abuts against the bottom of the sleeve rod 311 and can lift the sleeve rod 311.

[0038] The square clamping block 313 is snap-connected to a square groove 314 formed on the surface of the part housing 301. The sleeve rod 311 is slidably connected to an unlocking groove 315 formed on the surface of the part housing 301. The unlocking groove 315 is divided into a straight groove section and two bent sections at both ends. When the sleeve rod 311 is in the two bent sections, it respectively corresponds to two states of the stable snap connection and stable separation of the buckle block 305 and the limiting block 308.

[0039] Working principle: Before using this rapid installation structure for plastic pipes, it is necessary to first check the overall situation of the device to ensure that it can work properly. According to Figure 1 - Figure 5 As shown, first dock the connecting sleeve 201 and the docking sleeve 202, and pass the barb 204 through the neutral gear. Then rotate the second pipe body 102, so that the docking sleeve 202 drives the disc 203 to rotate, thereby making the barb 204 slide along the inclined surface of the trapezoidal strip 205. During this process, the barb 204 will pull two trapezoidal strips 205 on different sides closer, and further make the two discs 203 drive the sealing ring 206 closer and squeeze. After the barb 204 moves to the horizontal plane of the trapezoidal strip 205 and fits with another barb 204, the first pipe body 101 and the second pipe body 102 are stably connected. At this time, the mutually squeezed sealing ring 206 can prevent fluid leakage and ensure the sealing performance of the device.

[0040] During the installation process, the buckle block 305 will be snap-connected to the limiting block 308, thereby preventing the barb 204 from loosening from the trapezoidal strip 205.

[0041] After the snap block 305 is engaged with the limit block 308, the sleeve rod 311 is toggled and slides into the bent section of the unlocking groove 315, and the square clamping block 313 is inserted into the square groove 314, so that the sleeve rod 311 will not slide randomly in the unlocking groove 315 due to vibration, increasing the stability of the engagement between the snap block 305 and the limit block 308;

[0042] When the first pipe body 101 and the second pipe body 102 need to be disassembled, first hold the sleeve rod 311 to contract the first spring 310, and make the support plate 312 drive the square clamping block 313 to disengage from the square groove 314, then push the sleeve rod 311 to make the sliding block 307 move along the displacement groove 306 to the straight groove section of the unlocking groove 315, and then pull the sleeve rod 311 to slide along the straight groove section of the unlocking groove 315, and finally make the spring rod 302 drive the snap block 305 to contract and disengage from the engagement with the limit block 308, facilitating the subsequent rotation of the first pipe body 101 and the second pipe body 102.

[0043] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
