Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral wound joint technology, specifically to a quick-install spiral wound joint for pipe fittings. Background Technology
[0002] Spiral wound joints are high-performance pipe fittings formed by winding multiple layers of rubber with reinforcing materials (such as fabric cord or steel wire). Their unique structural design gives them significant advantages, making them particularly suitable for piping systems under complex operating conditions. Spiral wound joints consist of an inner rubber layer, multiple layers of fabric or steel wire winding, and an outer rubber layer. This structure provides the joint with a high-strength skeleton, enabling it to withstand high internal pressure and external impacts.
[0003] The existing technology has the following problems:
[0004] In existing technologies, spiral wound joints are installed and fixed by a number of bolts, and each bolt needs to be tightened individually to complete the installation. This results in slow, troublesome and laborious installation of spiral wound joints to pipes. In addition, the sealing of spiral wound joints in existing technologies is too simple, resulting in poor sealing performance.
[0005] Therefore, we need a quick-connect spiral splice for pipe fittings to solve the above problems. Utility Model Content
[0006] This utility model provides a quick-install spiral wound connector for pipe fittings to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A quick-connect spiral wound connector for pipe fittings includes a spiral wound connector body. Pipes are provided at both ends of the spiral wound connector body. Two sleeves are slidably connected to the outer surfaces of the pipes on both sides. Mounting rings are fixedly connected to both sides of the outer surface of the spiral wound connector body. A rubber sleeve is fixedly connected to the inner side of the spiral wound connector body. Several fixing plates are fixedly connected in a circular array to the left side of the mounting rings. An elastic plate is fixedly connected to the left end of each fixing plate. A limit groove is formed on the outer surface of the elastic plate. An inclined surface is provided on the left side of the outer surface of the elastic plate. Sealing components are provided on the opposite sides of the pipes on both sides, and the sealing components are mirror-image arranged.
[0009] A further improvement of this utility model is that the mounting ring, fixing plate, elastic plate, and limiting groove on the left and right sides are mirror images of each other.
[0010] A further improvement of this utility model is that: a positioning ring is fixedly connected to the outer surface of the pipes on both the left and right sides near the mounting ring, and the left side of the positioning ring has a ring array of several interconnected slots.
[0011] A further improvement of this utility model is that the interior of each of the card slots overlaps with the interior of the limiting groove, and the inner wall width of the limiting groove is greater than the inner wall width of the card slot.
[0012] A further improvement of this utility model is that the interior of several slots corresponds to the outer surface of the elastic plate, and the interior of several slots is inserted into the outer surface of the elastic plate.
[0013] A further improvement of this utility model is that the outer surface of the rubber sleeve is tightly inserted into and abuts against the inside of the pipe.
[0014] A further improvement of the present invention is that both sealing components include a rubber sleeve and a rubber ring, the left side of the rubber sleeve is fixedly connected to the surface of the pipe, and the right side of the rubber ring is fixedly connected to the inner wall of the mounting ring.
[0015] A further improvement of this utility model is that: a rubber insert ring is fixedly connected to the left side of the rubber ring, and an annular slot is provided on the right side of the rubber sleeve. The inside of the annular slot overlaps with the outer surface of the rubber insert ring, and the opposite surfaces of the rubber sleeve and the rubber ring overlap and press tightly together.
[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0017] 1. This utility model provides a quick-install spiral wound connector for pipe fittings. When installation is required, one end of the spiral wound connector is inserted into the pipe, allowing the elastic plate to enter the groove. At this time, the elastic plate deforms and bends. When the spiral wound connector is moved again, it returns to its original position due to the elasticity of the elastic plate. At the same time, the inside of the limiting groove is engaged inside the groove and contacts and blocks the outer surface of the positioning ring, thereby realizing the quick installation of the spiral wound connector. The design of this structure makes the operation simple and the installation fast.
[0018] 2. This utility model provides a quick-install spiral wound connector for pipe fittings. During installation, the rubber sleeve is inserted into the inside of the pipe and fits tightly. At the same time, the inside of the annular slot is in close contact with the rubber insert ring. At this time, the opposite surfaces of the rubber sleeve and the rubber ring are tightly fitted. Through this structure, the spiral wound connector enhances the sealing performance when connecting pipes. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Example 1: As Figures 1 to 4As shown, this utility model provides a quick-connect spiral wound connector for pipe fittings. The spiral wound connector body 1 connects to left and right pipes 2. Pipes 2 are located at both ends of the spiral wound connector body 1, and these pipes 2 connect to external pipe fittings. A sleeve 3 is provided on the outer surface of the sleeve 2 for sliding connection. The sleeve 3 can slide on the pipe 2, facilitating quick disassembly of the spiral wound connector body 1. Mounting rings 11 are fixedly connected to both sides of the outer surface of the spiral wound connector body 1, serving as the basic structure for fixing other components. A rubber sleeve 15 is fixedly connected to the inner side of the spiral wound connector body 1. The rubber sleeve 15 is inserted into the pipe 2 and makes tight contact with the inner wall of the pipe 2, providing a seal to prevent fluid leakage. Several fixing plates 12 are fixedly connected in a ring array on the left side of the mounting rings 11. The fixing plates 12 are used to fix elastic plates 13. Elastic plates 13 are fixedly connected to the left ends of the fixing plates 12. The elastic plates 13 are elastic and have limiting grooves 14 on their outer surfaces for positioning. The groove 211 on ring 21 engages to position the winding connector body 1. A bevel is provided on the left side of the outer surface of the elastic plate 13, which serves as a guide during installation, facilitating the smooth insertion of the elastic plate 13 into the groove 211. During insertion, the bevel contacts the inner wall of the groove 211, causing the elastic plate 13 to undergo compression deformation. The left and right mounting rings 11, fixing plate 12, elastic plate 13, and limiting groove 14 are mirror-image arranged. This mirror-image structure facilitates the positioning of the pipes on both sides. The left and right pipes 2 are connected by positioning rings 21 on the outer surface of the pipes 2 near the mounting ring 11. The left side of the positioning ring 21 has several interconnected slots 211 in a ring array. The inside of each slot 211 overlaps with the inside of the limiting groove 14. The inner wall width of the limiting groove 14 is greater than the inner wall width of the slot 211, which facilitates the limiting groove 14 to be inserted into the slot 211. Through the cooperation of the slot 211 and the elastic plate 13, the quick loading and unloading of the winding joint body 1 is achieved.
[0026] Example 2: Figures 1 to 4As shown, sealing components 22 are provided on the opposite sides of the left and right pipes 2. The left and right sealing components 22 are mirror images of each other to ensure the sealing of the connection of the spiral joint body 1. The left side of the rubber sleeve 221 in the sealing component 22 is fixedly connected to the surface of the pipe 2, and the right side of the rubber ring 222 is fixedly connected to the inner wall of the mounting ring 11. A rubber insert ring 223 is fixedly connected to the left side of the rubber ring 222. An annular slot 224 is opened on the right side of the rubber sleeve 221. During installation, the rubber insert ring 223 is inserted into the annular slot 224, and the opposite sides of the rubber sleeve 221 and the rubber ring 222 overlap and press tightly to further enhance the sealing effect and prevent fluid from leaking from the joint connection, forming multiple sealing defenses. The depth of the annular slot 224 is the same as the length of the rubber insert ring 223, and at the same time as insertion, the end face of the rubber insert ring 223 is also in a tight fit with the left side of the inner wall of the annular slot 224, thereby improving the sealing performance.
[0027] When it is necessary to disassemble the body 1 of the spiral joint, after disassembly through the pipe 2 and other objects, the sliding sleeve 3 is used to squeeze and deform the inclined surface in the elastic plate 13, so that the limiting groove 14 is separated from the left side of the positioning ring 21. Then, by moving the pipe 2 or the body 1 of the spiral joint, the disassembly effect can be achieved quickly.
[0028] Working principle: When connecting the spiral joint body 1, the rubber sleeve 15 in the spiral joint body 1 is first inserted into the inside of the pipe 2. At the same time as insertion, the inclined surface in the elastic plate 13 contacts the inner wall of the groove 211, causing the elastic plate 13 to deform and bend. When moved again, due to the elastic action of the elastic plate 13, it resets, causing the limiting groove 14 in the reset elastic plate 13 to be inserted into the inside of the groove 211, thus achieving quick installation. When disassembly is required, the worker moves the sleeve 3. When the sleeve 3 moves to the appropriate position, it contacts the inclined surface in the elastic plate 13, thereby squeezing and deforming the elastic plate 13, causing the inner wall of the limiting groove 14 to separate from the inner wall of the groove 211. At the same time, the left side of the inner wall of the limiting groove 14 separates from the surface of the positioning ring 21. Then, by moving the spiral joint body 1 and the pipe 2, the elastic plate 13 is moved out from the inside of the groove 211, thus achieving the effect of quick disassembly.
[0029] During installation, the rubber sleeve 15 is inserted into the pipe 2 and fits tightly against the inner wall of the pipe 2. The end faces of the rubber sleeve 221 and the rubber ring 222 are in close contact and fit tightly. At the same time, the outer surface of the rubber insert ring 223 is inserted into the inside of the annular slot 224 and fits tightly. This structure enables the spiral joint body 1 to have multiple sealing structures when it is installed and connected to the pipe 2, thereby improving the sealing performance.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
