Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite pipe connection technology, and specifically to a composite pipe connector. Background Technology
[0002] Composite pipes refer to a new type of pipe made of two or more materials with different properties, combined through specific processes (such as bonding, welding, winding, co-extrusion, etc.) to achieve comprehensive performance requirements that cannot be met by single-material pipes. The core of this definition is "composite". Its purpose is to solve the shortcomings of traditional single-material pipes (such as pure metal pipes or pure plastic pipes) in terms of corrosion resistance, strength, cost, or construction by complementing the advantages of the materials. When two sets of pipes are connected, a composite pipe connector is required.
[0003] Existing composite pipe connectors mostly use rigid connection structures, such as flange connections and threaded snaps, for assembly. Composite pipes are generally fixed in a designated location, which leads to deviations in the spacing between the pipe bodies of the two sets of composite pipes. The commonly used connectors have fixed lengths, which cannot meet the needs of rapid connection of two sets of pipes with different spacing at the joint. It is necessary to cut or re-joint the pipe body, which reduces the efficiency of composite pipe connection. Therefore, we need to propose a composite pipe connector. Utility Model Content
[0004] The purpose of this invention is to provide a composite pipe connector. Two sets of connectors are used to connect with two sets of pipes respectively. The two sets of connectors are connected by a flexible hose that can adjust the distance between them. Through the connection between the connectors, adjusting plates, and springs, the two sets of adjusting plates are squeezed together to bring the two sets of connectors closer and shorten the distance. The springs are always compressed. The two sets of pipes are aligned with one set of connectors respectively. Then, the pressure on the adjusting plates is released, and the two sets of connectors increase the distance under the action of the springs to squeeze and connect with one set of pipes. The springs always exert an outward squeezing force on the two sets of connectors, so that the inside of the connectors and one end of the pipes are tightly fitted together, thereby achieving the effect of rapid connection of the two sets of pipes. The device can also compensate for different distances at the connection point of the two sets of pipes, improving the adaptability of the connection device and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite pipe connector, comprising two sets of butt joints, the opposite ends of the two sets of butt joints being connected by a set of flexible hoses, and a set of pipes to be connected being inserted into the other end of each of the two sets of butt joints; an adjusting plate is fixedly installed on the outer side of each of the two sets of butt joints; three adjusting rods are fixedly installed on one side of one of the adjusting plates; one end of each of the three adjusting rods is movably inserted through one side of the other adjusting plate; and a set of springs is movably fitted onto the outer arc surface of each of the three adjusting rods located between the two adjusting plates; and a clamping assembly for fixing the pipe is installed inside the connection end of each of the two sets of butt joints.
[0006] Preferably, a set of limiting plates is fixedly installed at one end of the three sets of adjusting rods located outside the adjusting plate, and the two ends of the three sets of springs are respectively welded to the opposite sides of the two sets of adjusting plates.
[0007] Preferably, a set of sealing gaskets is embedded inside both sets of the connectors, and the mating ends of the two sets of pipes extend into the interior of the connectors and are tightly fitted against the set of sealing gaskets.
[0008] Preferably, the hose includes a rubber inner tube for connecting two sets of connectors, a metal wire mesh is fitted on the outside of the rubber inner tube, and a wear-resistant cloth is fitted on the outside of the metal wire mesh.
[0009] Preferably, the clamping assembly includes a rotating seat fixedly installed at the bottom of the inner cavity of the connector, and a set of clamping plates are rotatably connected to both ends of the rotating seat.
[0010] Preferably, the top of both sets of clamps is fixedly connected to a fixing plate, and a through groove is provided through the upper part of each set of joints. The tops of the two sets of fixing plates pass through the through grooves to the top of the joints, and the two sets of fixing plates are fixed by screws.
[0011] Preferably, the two sets of clamping plates are arranged in an arc shape, and a set of rubber pads are fixedly installed on the clamping surface of each set of clamping plates.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes the connection between the connector, adjusting plate, and spring. By pressing two sets of adjusting plates together, the two sets of connectors are brought closer together and the distance between them is shortened. The spring remains compressed, aligning each of the two sets of pipes with a connector. Then, the pressure on the adjusting plates is released, and the two sets of connectors, under the action of the spring, increase the distance between them and each set of pipes for a pressing connection. The spring always exerts an outward pressing force on the two sets of connectors, ensuring that the inside of the connector is tightly fitted to one end of the pipe, thus achieving a rapid connection between the two sets of pipes. Furthermore, the device can compensate for different distances at the connection points of the two sets of pipes, improving the adaptability of the connection device.

The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This utility model provides a composite pipe connector, including two sets of connectors 1. The opposite ends of the two sets of connectors 1 are connected by a set of flexible hoses 3. A set of pipe bodies 2 to be connected is inserted into the other end of each set of connectors 1. An adjusting plate 4 is fixedly installed on the outside of each set of connectors 1. Three adjusting rods 5 are fixedly installed on one side of one set of adjusting plate 4. One end of the three adjusting rods 5 is movably inserted through one side of the other set of adjusting plate 4. A set of springs 6 is movably fitted on the outer arc surface of the three adjusting rods 5 between the two sets of adjusting plate 4. A clamping assembly 9 for fixing the pipe body 2 is installed inside the connection end of each set of connectors 1.
[0023] In use, two sets of connectors 1 are used to connect with two sets of pipes respectively. The two sets of connectors 1 are connected by flexible hoses 3 that can adjust the distance between them. Through the connection between connectors 1, adjusting plates 4, and springs 6, the two sets of adjusting plates 4 are squeezed to bring the two sets of connectors 1 closer together and shorten the distance. Springs 6 are always compressed. The two sets of pipes are aligned with one set of connectors 1 respectively. Then, the squeezing of adjusting plates 4 is released. Under the action of springs 6, the distance between the two sets of connectors 1 increases and they are squeezed to connect with one set of pipes 2. Springs 6 always exert an outward squeezing force on the two sets of connectors 1, so that the inside of connector 1 and one end of pipe 2 are tightly pressed together, thereby achieving the effect of rapid connection of the two sets of pipes. The device can compensate for different distances at the connection point of the two sets of pipes 2, improving the adaptability of the connection device. The clamping components 9 installed inside the two sets of connectors 1 clamp and fix the pipes 2, so that the connector is always fixed at one end of the pipe 2, avoiding the problem of loosening of the connector due to vibration.
[0024] A set of limiting plates 7 are fixedly installed at one end of the three sets of adjusting rods 5 on the outside of the adjusting plate 4. The two ends of the three sets of springs 6 are welded to the opposite sides of the two sets of adjusting plates 4 respectively. By setting the limiting plates 7, the maximum distance between the two sets of adjusting plates 4 can be limited, avoiding the loosening of the hose 3 by pulling it. At the same time, it prevents one of the movable adjusting plates 4 from slipping off one end of the adjusting rod 5. The two ends of the springs 6 are welded to the adjusting plates 4 to improve the stability of the springs 6 during installation and use.
[0025] Both sets of connectors 1 have a set of sealing gaskets 10 embedded inside. The mating ends of the two sets of tubes 2 extend into the interior of connectors 1 and are tightly fitted with a set of sealing gaskets 10. The sealing gaskets 10 improve the airtightness when the tubes 2 are connected to connectors 1.
[0026] The hose 3 includes a rubber inner tube 31 for connecting two sets of connectors 1. A metal wire mesh 32 is fitted on the outside of the rubber inner tube 31, and a wear-resistant cloth 33 is fitted on the outside of the metal wire mesh 32. Through the bending characteristics of the three-layer structure of the hose 3—rubber inner tube 31, metal wire mesh 32, and wear-resistant cloth 33—the hose 3 can be bent at a certain angle without affecting the normal flow of the internal liquid, thereby meeting the requirements for adjusting the distance between the two sets of connectors 1.
[0027] The clamping assembly 9 includes a rotating seat 91 fixedly installed at the bottom of the inner cavity of the connector. Both ends of the rotating seat 91 are rotatably connected to a set of clamping plates 92. The tops of the two sets of clamping plates 92 are fixedly connected to a fixing plate 94. A through groove 8 is provided through the upper part of each set of connectors 1. The tops of the two sets of fixing plates 94 pass through the through groove 8 to the top of the connector 1, and the two sets of fixing plates 94 are fixed by screws 95. When the tube body 2 and the connector 1 are mated and sealed, the nuts rotate on the screws 95, so that one end of the two sets of clamping plates 92 moves closer to each other, while the other end rotates. The two sets of clamping plates 92 clamp and fix the tube body 2, thereby achieving a locked state between the connector 1 and the tube body 2.
[0028] The two sets of clamping plates 92 are arranged in an arc shape, and a set of rubber pads 93 are fixedly installed on the clamping surface of each set of clamping plates 92. The arc shape of the clamping plates 92 makes the clamping plates 92 fit more closely to the outer arc surface of the tube body 2, increasing the contact area and improving the clamping stability. The rubber pads 93 not only enhance the friction, but also prevent the clamping plates 92 from damaging the surface of the tube body 2, which is especially suitable for composite tube bodies 2 whose surfaces are easily scratched.
[0029] In practical use: Based on the required spacing between the two sets of pipes, press the two sets of adjusting plates 4 to shorten the distance between the two sets of connectors 1 so that they can be placed between the two sets of pipes. Then, fit one set of connectors 1 onto one set of pipe bodies 2. Slowly release the pressure on the adjusting plates 4, allowing the other set of connectors 1 to be slowly fitted onto one end of the other set of pipe bodies 2. Then, completely release the pressure on the adjusting plates 4. Under the action of the spring 6, the interiors of the two sets of connectors 1 respectively abut and seal against one end of one set of pipe bodies 2, thus achieving a quick connection between the two sets of pipe bodies 2. Then, by rotating the nut clockwise, the two sets of clamping plates 92 clamp and fix the pipe body 2. Due to the compatibility between the clamping plates 92 and the pipe body 2, the distance between them is very small, eliminating the need to consider the problem of the two sets of clamping plates 92 not being able to move a wide range on the screw 95. Through the above device setup, the effect of quick connection of the pipe body 2 is achieved.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
