Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline technology, and more specifically to an adjustable multi-pipe PVC three-pipe flexible hose. Background Technology

[0002] PVC three-way hose is a type of hose made of polyvinyl chloride (PVC). It is typically designed with three independent channels or chambers, hence the name "three-way hose". This type of hose has a smooth interior, which helps to achieve optimal flow rate. It also has good flexibility and durability, and can adapt to various bending and twisting situations without being easily damaged. PVC three-way hose is not suitable for conveying various media such as air, flue gas, dust and powder. It is widely used in industrial production, ventilation systems, dust removal equipment and other fields.

[0003] The shortcomings of existing PVC three-wire hoses:

[0004] Firstly, during the installation of PVC three-wire flexible pipes, in order to ensure that the pipes do not deform due to mutual compression or external force during installation, it is necessary to adjust the spacing between the pipes. In actual operation, there is no special equipment to adjust the spacing between the pipes, and the spacing can only be adjusted by stones or bricks, which is very inconvenient.

[0005] Secondly, when adjusting the spacing of the hose, hard objects may come into contact with the hose body. Over a long period of time, scratches may be generated due to friction, and these damages will reduce the service life of the hose. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable multi-pipe PVC three-wire hose to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: an adjustable multi-pipe PVC three-wire hose, including a frame body, the top of the frame body is provided with an movable port, the top of the movable port is movably connected to a first mounting block, the top of the first mounting block is movably connected to a second connecting block, bolts are movably connected to both sides of the second connecting block, one side of the inner surface of the frame body is provided with an movable port, the inner surface of the movable port is movably connected to a transmission rod, and one side of the transmission rod is fixedly connected to a worm gear;

[0008] Furthermore, the first mounting block has fixing holes on both sides of its top, a first mounting groove on its top, a protrusion movably connected to the inner surface of the first mounting groove, and a rubber block fixedly connected to the inner surface of the protrusion. The second mounting block has a second mounting groove at its bottom, a protrusion movably connected to the inner surface of the second mounting groove, and the first mounting groove movably connected to the outer surface of the bolt.

[0009] Furthermore, a worm is movably connected to the bottom of the outer surface of the worm gear, support blocks are movably connected to both ends of the worm, a knob is fixedly connected to the front of the worm, a transmission rod is fixedly connected to the other side of the transmission rod, and a screw rod is fixedly connected to the other side of the transmission rod.

[0010] Furthermore, a movable block is fixedly connected to the bottom of the first mounting block, and a limiting block is fixedly connected to the front and back of the movable block, with a limiting groove movably connected to the outer surface of the limiting block.

[0011] Furthermore, the main frame is made of high-strength PVC material.

[0012] Furthermore, the surface of the limiting block is smoothed to reduce friction with the inner wall of the limiting groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In use, the PVC pipe is placed inside the rubber block, and then the rubber block is placed inside the first mounting block and the second mounting block. The protrusion is aligned with the inside of the first mounting groove and the second mounting groove. Then, bolts are passed through the fixing holes and tightened. The rubber block has a certain elasticity and friction. When the PVC pipe is placed between the first mounting block and the second mounting block and the bolts are tightened, the friction between the pipe and the mounting block can be further increased, making the connection more firm and stable.

[0015] 2. When it is necessary to adjust the spacing between various pipes, rotating the knob causes the worm gear to start rotating. After the worm gear starts rotating, the worm wheel starts rotating. The self-locking characteristic between the worm gear and the worm wheel ensures that the mounting block will not move after being in a fixed position. When the worm wheel starts rotating, the transmission rod drives the threaded rod to start rotating. The movable block has a thread inside that matches the threaded rod, allowing the movable block to move within the movable opening. The limit blocks at both ends of the movable block are locked in the limit grooves, which allows the first mounting block to slide stably. This allows construction personnel to accurately control the spacing between pipes, ensuring that each pipe is in the correct position and avoiding pipe deformation or damage caused by improper spacing.

The adjustable multi-pipe PVC three-wire hose involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1-4 This utility model provides an adjustable multi-pipe PVC three-way flexible hose, including a frame body 1. The top of the frame body 1 has an opening 101 and a through groove 102. The top of the opening 101 is movably connected to a first mounting block 2. The top of the first mounting block 2 is movably connected to a second mounting block 205. Bolts 207 are movably connected to both sides of the second mounting block 205. The inner surface of the frame body 1 has an opening 101 on one side. A transmission rod 404 is movably connected to the inner surface of the opening 101. A worm gear 403 is fixedly connected to one side of the transmission rod 404.

[0023] In a preferred embodiment, fixing holes 201 are provided on both sides of the top of the first mounting block 2, a first mounting groove 202 is provided on the top of the first mounting block 2, a protrusion 204 is movably connected to the inner surface of the first mounting groove 202, a rubber block 203 is fixedly connected to the inner surface of the protrusion 204, a second mounting groove 206 is provided at the bottom of the second mounting block 205, a protrusion 204 is movably connected to the inner surface of the second mounting groove 206, and the first mounting groove 202 is movably connected to the outer surface of the bolt 207.

[0024] In a preferred embodiment, a worm 402 is movably connected to the bottom of the outer surface of the worm gear 403, and support blocks 401 are movably connected to both ends of the worm 402. A knob 4 and a transmission rod 404 are fixedly connected to the front of the worm 402, and a threaded rod 405 is fixedly connected to the other side of the transmission rod 404.

[0025] In a preferred embodiment, a movable block 3 is fixedly connected to the bottom of the first mounting block 2, and a limiting block 301 is fixedly connected to the front and back of the movable block 3, and a limiting groove 103 is movably connected to the outer surface of the limiting block 301.

[0026] In a preferred embodiment, the frame body 1 is made of high-strength PVC material.

[0027] In a preferred embodiment, the surface of the limiting block 301 is smoothed to reduce friction with the inner wall of the limiting groove 103.

[0028] The working principle of this utility model is as follows: During use, the PVC pipe is placed inside the rubber block 203, then the rubber block 203 is placed inside the first mounting block 2 and the second mounting block 205, with the protrusion 204 aligned with the first mounting groove 202 and the second mounting groove 206. Then, bolts 207 are passed through the fixing hole 201 and tightened. The rubber block 203 has a certain elasticity and friction. When it is placed between the first mounting block 2 and the second mounting block 205 in the PVC pipe and the bolts 207 are tightened, the friction between the pipe and the mounting block is further increased, making the connection more secure and stable. When it is necessary to adjust the spacing between the pipes, the knob 4 is rotated to move the worm gear 402. The rotation begins. After the worm gear 402 starts rotating, the worm wheel 403 starts rotating. The self-locking characteristic between the worm gear 402 and the worm wheel 403 ensures that the mounting block will not move after it is in a fixed position. After the worm wheel 403 starts rotating, the transmission rod 404 starts to drive the threaded rod 405 to rotate. The movable block 3 has a thread inside and is adapted to the threaded rod 405, which allows the movable block 3 to move within the movable opening 101. The limiting blocks 301 at both ends of the movable block 3 are locked in the limiting grooves 103, which allows the first mounting block 2 to slide stably. This helps construction personnel to accurately control the spacing between pipes, ensuring that each pipe is in the correct position and avoiding pipe deformation or damage caused by improper spacing.
