Description

Technical Field

[0001] The utility model relates to the field of polyethylene pipes, in particular to a polyethylene pipe with a quick-disassembly structure. Background Art

[0002] Polyethylene pipe is a common and frequently used pipe in our lives. Gas pipelines and water pipes are the areas where polyethylene pipes are widely used. Polyethylene pipes can also be called PE pipes because the main material of polyethylene pipes is PE resin.

[0003] Chinese patent authorization application number: CN202021963562.3 provides a polyethylene pipe that is easy to disassemble and install. The solution is provided with a first connecting block at the right end of the polyethylene pipe body near the inner wall of the polyethylene pipe body, and the outer surface of the first connecting block is provided with a first external thread. The left end of the polyethylene pipe body is provided with a second connecting block near the outer wall of the polyethylene pipe body, and the inner surface of the second connecting block is provided with a first internal thread, which facilitates threaded connection between the two polyethylene pipe bodies, making it easy to disassemble and install the two polyethylene pipe bodies. At the same time, a sealing groove is provided at the bending part of the polyethylene pipe body and the first connecting block, and a sealing gasket is sleeved in the sealing groove, so that the sealing between the two polyethylene pipe bodies is enhanced, reducing the risk of water and gas leakage inside the polyethylene pipe.

[0004] The existing polyethylene pipes have certain disadvantages when in use. First, the polyethylene pipes use a single threaded connection structure. When the polyethylene pipes are subjected to external forces, the possibility of falling off increases. In addition, the installation and disassembly of the polyethylene pipes are also more laborious, resulting in reduced convenience in the use and disassembly of the polyethylene pipes. For this reason, we propose a polyethylene pipe with a quick-release structure. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a polyethylene pipe with a quick-release structure. By setting a positioning clamp block and a clamping frame, when the positioning clamp block with an L-shaped structure is squeezed, the clamping frame can be separated from the clamping slot, so that the connected polyethylene pipe body and the connecting pipe can be quickly disassembled more labor-savingly, which is used to solve the problem that the polyethylene pipe is also relatively labor-intensive to install and disassemble; a clamping slot is set, and a pair of clamping slots can limit the positioning clamp block and the clamping frame, so that the connection between the polyethylene pipe body and the connecting pipe is more stable; a positioning rod is set, and the positioning rod can be pulled to cooperate with the force of the reset spring to drive the front end clamping head to move, so that the clamping head can be easily separated or clamped with the outer end of the arc ring; the positioning slot is set to be adapted to the arc ring for clamping, and a clamping structure is formed at the connection between the polyethylene pipe body and the connecting pipe, so as to prevent the connecting pipe and the polyethylene pipe body from falling off during installation, thereby improving the anti-falling effect of the pipeline connection installation.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A polyethylene pipe with a quick-release structure comprises a main body mechanism, the outer end of the main body mechanism is fixedly connected with a positioning mechanism, and the outer side of the positioning mechanism is installed with a connecting mechanism;

[0008] The positioning mechanism includes a positioning clamp block, which is symmetrically distributed on the outer end of the main body mechanism. The positioning clamp block is L-shaped. A pressing groove is opened at the inner end of the positioning clamp block. A spring ring is fixedly connected to the inner end of the pressing groove. Both ends of the positioning clamp block are fixedly connected to a bracket.

[0009] By installing the positioning clamp and the clamping frame, when the positioning clamp with an L-shaped structure is squeezed, the deformed positioning clamp drives the clamping frames at both ends, so that the clamping frames can be separated from the clamping slots, so that the connected polyethylene pipe body and the connecting pipe can be quickly disassembled more labor-savingly, thereby improving the convenience of using and connecting the polyethylene pipe.

[0010] Furthermore, a card slot is provided at the outer end of the card frame, and a movable slot is provided at the bottom of the card frame.

[0011] By installing the card slot, the connection between the polyethylene pipe body and the connecting pipe can be made more stable, and will not fall off or separate when subjected to direct external force, thereby improving the stability between the device structures.

[0012] Furthermore, the main body mechanism comprises a polyethylene tube body, the outer end of the polyethylene tube body is movably connected with a connecting tube, and the outer end of the polyethylene tube body is sleeved with a sleeve.

[0013] By installing the sleeve, the external force acting directly on the connection of the polyethylene pipe body can be reduced, making the connection between the pipes more stable.

[0014] Furthermore, the outer end of the sleeve is movably connected with a positioning sleeve, and the inner end of the positioning sleeve is provided with a positioning groove.

[0015] By installing the positioning groove, a clamping structure can be formed at the connection between the polyethylene pipe body and the connecting pipe, which effectively prevents the connecting pipe and the polyethylene pipe body from falling off during installation, thereby improving the anti-falling effect of the pipeline connection installation.

[0016] Furthermore, an arc ring is slidably connected to the inner end of the positioning groove, the arc ring is located at the inner end of the sleeve, and a positioning frame is installed on the front side of the sleeve.

[0017] By installing the positioning frame, the positioning rod and the outer end of the clamp can be stably connected to the main body, making the structural installation connection between the device more stable.

[0018] Furthermore, the positioning frames are symmetrically distributed, the positioning frames are located at the outer ends of the positioning sleeves, and the inner ends of the positioning frames are slidably connected with positioning rods.

[0019] By installing the positioning rod, the positioning rod can be pulled to allow the clamping head to be easily separated or clamped from the outer end of the arc ring, making the polyethylene pipe more stable during installation and more convenient during disassembly, further improving the stability and convenience of installation and disassembly of the polyethylene pipe.

[0020] Furthermore, a return spring is sleeved on the outer end of the positioning rod, a clamp is installed on the front side of the return spring, the clamp is located at the top end of the positioning rod, and a receiving groove is opened on the outer end of the clamp.

[0021] By installing the receiving groove, the stability of the connection between the polyethylene pipe body and the connecting pipe can be improved, and the connection effect of the pipeline is further improved.

[0022] Furthermore, the receiving groove is located at the outer end of the arc-shaped ring, a limiting groove is provided behind the receiving groove, and the receiving groove is located at the inner end of the positioning frame.

[0023] By installing the limiting groove, the adjustment movement of the positioning rod and the return spring can be more stable without offset, thereby improving the stability of the device being fixed between the pipes.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. By setting the positioning clamp block and the clamping frame, when the positioning clamp block with an L-shaped structure is squeezed, the positioning clamp block can produce adjustment deformation, and the deformed positioning clamp block drives the clamping frames at both ends, so that the clamping frames can be separated from the clamping slots, so that the connected polyethylene pipe body and the connecting pipe can be quickly disassembled more labor-savingly, thereby improving the convenience of using and connecting the polyethylene pipe;

[0026] 2. By setting the card slots, a pair of card slots can limit the positioning clamp block and the card frame, so that the connection between the polyethylene pipe body and the connecting pipe is more stable, and it will not fall off or separate when subjected to direct external force, thereby improving the stability of the device structure;

[0027] 3. By setting a positioning rod, the positioning rod can be pulled to cooperate with the force of the reset spring to drive the front end of the clamp to move, so that the clamp can be easily separated or clamped with the outer end of the arc ring, making the polyethylene pipe more stable during installation and more convenient during disassembly, further improving the stability and convenience of installation and disassembly of the polyethylene pipe;

[0028] 4. By setting the positioning groove, the positioning groove can be adapted and snap-fitted with the arc ring, thereby forming a snap-fit ​​structure at the connection between the polyethylene pipe body and the connecting pipe, effectively preventing the connecting pipe and the polyethylene pipe body from falling off during installation, thereby improving the anti-falling effect of the pipeline connection installation.

[0037] Reference Figure 1-5 As shown, a polyethylene tube with a quick-release structure in a preferred embodiment of the utility model comprises a main body mechanism 1, a positioning mechanism 2 is fixedly connected to the outer end of the main body mechanism 1, and a connecting mechanism 3 is installed on the outer side of the positioning mechanism 2;

[0038] The positioning mechanism 2 includes a positioning clamp 201, which is symmetrically distributed at the outer end of the main body mechanism 1. The positioning clamp 201 is an L-shaped structure. A pressing groove 202 is opened at the inner end of the positioning clamp 201. A spring ring 203 is fixedly connected to the inner end of the pressing groove 202. Both ends of the positioning clamp 201 are fixedly connected to a bracket 204.

[0039] Reference Figure 2-4 The outer end of the card frame 204 is provided with a card slot 205 , and the lower part of the card frame 204 is provided with a movable slot 206 .

[0040] By installing the positioning clamp 201 and pressing it to deform, a pressing groove 202 is provided at the inner end of the positioning clamp 201, which can facilitate the deformation of the positioning clamp 201 and the spring ring 203 at the inner end. At this time, the deformed positioning clamp 201 drives the clamping frames 204 at both ends, so that the clamping frames 204 can be separated from the clamping grooves 205, so that the connected polyethylene tube body 101 and the connecting tube 102 can be quickly disassembled more labor-savingly. A pair of clamping grooves 205 can limit the positioning clamp 201 and the clamping frame 204, so that the connection between the polyethylene tube body 101 and the connecting tube 102 is more stable, and it will not fall off or separate when subjected to direct external force.

[0041] Reference Figure 1 As shown, the main body mechanism 1 includes a polyethylene tube body 101 , the outer end of the polyethylene tube body 101 is movably connected with a connecting tube 102 , and the outer end of the polyethylene tube body 101 is sleeved with a sleeve 103 .

[0042] Reference Figure 1-2 As shown, the outer end of the sleeve 103 is movably connected to a positioning sleeve 104 , and the inner end of the positioning sleeve 104 is provided with a positioning groove 105 .

[0043] Reference Figure 1-2 As shown, the inner end of the positioning groove 105 is slidably connected with an arc ring 106 , the arc ring 106 is located at the inner end of the sleeve 103 , and a positioning frame 301 is installed on the front side of the sleeve 103 .

[0044] By installing the positioning groove 105, it can be adapted and snap-fitted with the arc ring 106, so as to form a snap-fit ​​structure at the connection between the polyethylene tube body 101 and the connecting tube 102, which can effectively prevent the connecting tube 102 and the polyethylene tube body 101 from falling off during installation. The sleeve 103 can form a connecting support structure at the outer end of the polyethylene tube body 101, reduce the external force directly acting on the connection of the polyethylene tube body 101, and make the connection between the pipes more stable.

[0045] Reference Figure 2 and Figure 4 As shown, the positioning frames 301 are symmetrically distributed. The positioning frames 301 are located at the outer end of the positioning sleeve 104 , and the inner end of the positioning frames 301 is slidably connected with the positioning rod 302 .

[0046] Reference Figure 4 As shown, a return spring 303 is sleeved on the outer end of the positioning rod 302 , a clamp 304 is installed on the front side of the return spring 303 , the clamp 304 is located at the top end of the positioning rod 302 , and a receiving groove 305 is opened on the outer end of the clamp 304 .

[0048] By installing the positioning rod 302 and pulling it, the front end clamp 304 can be driven to move under the force of the reset spring 303, so that the clamp 304 can be easily separated or clamped with the outer end of the arc ring 106, making the polyethylene tube more stable during installation and more convenient to disassemble. The receiving groove 305 is adapted to the clamp 304, which can improve the stability of the connection between the polyethylene tube body 101 and the connecting tube 102. The limiting groove 306 can guide the positioning rod 302 and the reset spring 303 for adjustment and movement, so that the adjustment and movement of the positioning rod 302 and the reset spring 303 are more stable and will not cause deviation, thereby improving the stability of the fixation between the pipes of the device.

[0049] Specific implementation process: when the pipeline only needs to be disassembled quickly, the positioning rod 302 is pulled. The positioning rod 302 can be pulled in cooperation with the force of the reset spring 303 to drive the front end clamp 304 to move, so that the clamp 304 can be easily separated or clamped with the outer end of the arc ring 106, making the polyethylene pipe more stable during installation. The limiting groove 306 can guide the positioning rod 302 and the reset spring 303 for adjustment and movement, so that the positioning rod 302 and the reset spring 303 can be adjusted and moved more stably without offset. During installation, the receiving groove 305 is adapted to the clamp 304, which can improve the stability of the connection between the polyethylene pipe body 101 and the connecting pipe 102.

[0050] When the pipeline is in use, the positioning groove 105 can be adapted and snap-fitted with the arc ring 106, thereby forming a snap-fit ​​structure at the connection between the polyethylene pipe body 101 and the connecting pipe 102, effectively preventing the connecting pipe 102 and the polyethylene pipe body 101 from falling off during installation, thereby improving the anti-falling effect of the pipeline connection installation.

[0051] Then the L-shaped positioning clamp 201 is squeezed, and a pressing groove 202 is provided at the inner end of the positioning clamp 201, which can facilitate the deformation of the positioning clamp 201 and the spring ring 203 at the inner end. At this time, the deformed positioning clamp 201 drives the clamping frames 204 at both ends, so that the clamping frames 204 can be separated from the clamping groove 205, so that the connected polyethylene pipe body 101 and the connecting pipe 102 can be quickly disassembled more labor-savingly, thereby improving the convenience of using and connecting the polyethylene pipe.
