Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe joint technology, and in particular to a pipe joint. Background Technology
[0002] Pipe fittings are crucial connecting elements in fluid transport systems. Their core function is to reliably and sealingly connect two adjacent pipe sections, ensuring stable and leak-free fluid flow along a predetermined path within the system. Based on the rigidity of the connected pipes, pipe fittings are generally classified into two main categories: rigid pipe fittings and flexible pipe fittings. Rigid pipe fittings are primarily used to connect non-flexible metal pipes (such as stainless steel and copper pipes), and their connection method prioritizes higher structural strength, better sealing, and vibration resistance. Flexible pipe fittings are mainly used to connect high-pressure braided or spiral-wound hoses.
[0003] However, most conventional pipe fittings connect pipes to pipe fittings by threading, but this connection method has poor sealing effect, which makes fluid leakage easy. Utility Model Content
[0004] The purpose of this invention is to provide a pipe joint that solves the problem that conventional pipe joints mostly connect pipes and pipe joints by threaded locking, but this connection method has poor sealing effect and leads to easy fluid leakage.
[0005] To achieve the above objectives, this utility model provides a pipe joint, including a joint body and a connecting device. The connecting device is installed on the joint body. It also includes a sealing device, which includes a fixing ring, a sleeve, a threaded sleeve, a sealing cone sleeve, and a connecting assembly. The fixing ring is fixedly installed on the joint body, the sleeve is fixedly installed on the fixing ring, the threaded sleeve is fixedly installed inside the joint body, and the sealing cone sleeve is slidably installed on the sleeve through the connecting assembly.
[0006] The sleeve assembly includes a guide rod and a transverse groove. The guide rod is fixedly installed on the outside of the sleeve, and the transverse groove is disposed on the sealing cone sleeve.
[0007] The threaded sleeve is further provided with a guide sleeve, which is fixedly installed on the threaded sleeve.
[0008] The connecting device includes a connecting disc, a sealing ring, and a locking assembly. The connecting disc is fixedly installed on the connector body; the sealing ring is fixedly installed on the connector body and close to the connecting disc; and the locking assembly is disposed on the connecting disc.
[0009] The locking assembly includes a stud and a nut, with the stud penetrating the connecting disc and the nut threadedly engaging with the stud.
[0010] This utility model discloses a pipe connector. In use, the sealing cone sleeve slides into the sleeve through the sliding engagement of the transverse groove and the guide rod. Then, the pipe is screwed into the connector body through the threaded sleeve inside the connector body, so that the sealing cone sleeve slides into the inside of the pipe. After both connector bodies are connected to the pipe, the connecting discs are mated, and the two connector bodies are locked together by the stud and the nut, so that the two pipes are connected. The sealing cone sleeve on the sleeve ensures the sealing of the connection between the connector body and the pipe. Attached Figure Description

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0017] The embodiment of this application is as follows:
[0018] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of a pipe joint according to this utility model. Figure 2 This is a structural schematic diagram of the sealing device of this utility model. Figure 3 This is a schematic diagram of the sealing cone sleeve of this utility model.
[0019] This utility model provides a pipe joint: including a joint body 101 and a connecting device, and also includes a sealing device. The sealing device includes a fixing ring 102, a sleeve 103, a threaded sleeve 104, a sealing cone sleeve 105, and a connecting assembly. The connecting assembly includes a guide rod 106 and a transverse groove 107. The threaded sleeve 104 is also provided with a guide sleeve 108. The connecting device includes a connecting disc 109, a sealing ring 110, and a locking assembly. The locking assembly includes a stud 111 and a nut 112. The aforementioned solution solves the problem that conventional pipe joints mostly achieve the connection between pipes and pipe joints through threaded locking, but this connection method has poor sealing effect, leading to easy fluid leakage.
[0020] In this embodiment, the sealing performance of the connection between the joint body 101 and the pipe is ensured by crimping the sealing cone sleeve 105 and the pipe.
[0021] The fixing ring 102 is fixedly installed on the connector body 101, the sleeve 103 is fixedly installed on the fixing ring 102, the threaded sleeve 104 is fixedly installed inside the connector body 101, and the sealing cone sleeve 105 is slidably installed on the sleeve 103 through the sleeve assembly. The fixing ring 102 is welded inside the connector body 101, and the sleeve 103 is welded inside the fixing ring 102. The threaded sleeve 104 has threads on its inner side, and the sealing cone sleeve 105 has a conical structure. The pipe is connected to the connector body 101 through the threaded sleeve 104. The connecting device connects the two connector bodies 101 and further connects the two pipes. At the same time, the sealing of the connection between the connector body 101 and the pipe is ensured by the compression of the sealing cone sleeve 105 and the pipe.
[0022] Secondly, the guide rod 106 is fixedly installed on the outside of the sleeve 103; the transverse groove 107 is provided on the sealing cone sleeve 105, the guide rod 106 is circumferentially welded to the outside of the sleeve 103, the transverse groove 107 is structurally adapted to the guide rod 106, and the sliding fit between the transverse groove 107 and the guide rod 106 facilitates the sliding of the sealing cone sleeve 105 into the sleeve 103.
[0023] Secondly, the guide sleeve 108 is fixedly installed on the threaded sleeve 104. The inner side of the guide sleeve 108 has a tapered structure. The guide sleeve 108 is welded to the threaded sleeve 104. The guide sleeve 108 facilitates the entry of the pipe into the threaded sleeve 104.
[0024] Furthermore, the connecting disc 109 is fixedly installed on the connector body 101; the sealing ring 110 is fixedly installed on the connector body 101 and close to the connecting disc 109; the locking assembly is disposed on the connecting disc 109, the connecting disc 109 is welded to the connector body 101, the connecting disc 109 is provided with multiple sets of round holes, and the sealing ring 110 is bonded to the connector body 101. By locking the connecting disc 109 through the locking assembly, the two connector bodies 101 can be connected. The sealing ring 110 ensures the sealing performance of the connection between the two connector bodies 101.
[0025] Finally, the stud 111 passes through the connecting disc 109; the nut 112 is threadedly engaged with the stud 111, and there are four sets of both the stud 111 and the nut 112. The engagement of the stud 111 and the nut 112 facilitates the locking of the two connector bodies 101.
[0026] In this embodiment, during use, the sealing cone sleeve 105 is slid into the sleeve 103 through the sliding engagement of the transverse groove 107 and the guide rod 106. Then, the pipe is screwed into the connector body 101 through the threaded sleeve 104 inside the connector body 101, so that the sealing cone sleeve 105 slides into the inside of the pipe. After both connector bodies 101 are connected to the pipe, the connecting disc 109 is mated, and the two connector bodies 101 are locked by the stud 111 and the nut 112, so that the two pipes are connected. The sealing cone sleeve 105 on the sleeve 103 ensures the sealing of the connection between the connector body 101 and the pipe.
