Description

Technical Field

[0001] The invention belongs to the field of pipelines, and more particularly relates to a pipeline joint and a release auxiliary component of the pipeline joint. Background Art

[0002] In modern buildings, industrial production and daily life, piping systems play a key role in transporting fluids (including liquids, gases and even plasma). From domestic water systems to complex networks in schools, medical facilities and commercial buildings, piping systems ensure the effective circulation and utilization of various fluids such as hot and cold water, air, ethylene glycol, compressed air, inert gases, chemicals, wastewater, cooling media and coatings. Pipes are made of a variety of materials, including copper, stainless steel, CPVC (chlorinated polyvinyl chloride) and PEX (cross-linked polyethylene). The selection of these materials is often based on fluid properties, pressure requirements and cost considerations. In this discussion, the term "pipeline" or "piping system" refers to the overall system that includes pipes, pipelines, pipeline components and their combinations.

[0003] As the basis for building complex piping systems, pipe connections must flexibly adapt to the needs of different layouts and direction changes. Pipe systems can be efficiently assembled by using various accessories and valves, such as elbows, tees, connectors, and ball valves and stop valves for size conversion, terminal connection, and flow control.

[0004] Historically, pipe connections have relied mainly on welding and brazing techniques, which are effective but present many challenges. Brazing not only requires a lot of preparation work, such as cleaning the pipe ends and applying flux, but also requires professional skills and protective equipment. The process is time-consuming and poses safety risks. In addition, brazing materials (such as solder, welding torch, etc.) and subsequent inspections are expensive and not suitable for all material combinations.

[0005] In recent years, push-fit technology has gradually become the new favorite for pipe connection due to its simplicity, speed and low material requirements. This technology only requires pipes, quick-connect fittings, deburring tools and cutters to complete the installation, greatly simplifying the operation process. The core of the push-fit connection lies in the ring teeth (collet, clamping ring), which are designed to automatically clamp when the pipe is inserted, forming a reliable seal and connection without the need for additional tools or welding.

[0006] However, the early push-fit connection technology also has its shortcomings, such as the plastic clamp ring support is prone to failure when subjected to tension, and it is necessary to rely on additional stamping, gluing or threaded caps to fix the ring teeth, which not only increases manufacturing costs but also reduces production efficiency. The threaded cap method also needs to consider the thread processing cost and the use of sealants, while the stamping method may cause the ring teeth to be permanently fixed and difficult to repair or replace.

[0007] In addition, traditional connection technologies are often limited to connections between similar materials, and lack effective solutions for the combination of copper with different materials such as CPVC, PEX, stainless steel, etc. Once a problem occurs, it is usually necessary to replace the entire accessory instead of repairing the faulty part, which not only wastes resources but also increases maintenance costs. Summary of the invention

[0008] In view of the deficiencies in the prior art, an object of the present invention is to provide a pipe joint release auxiliary component, which has the advantage of easily removing the pipe from the pipe joint.

[0009] To achieve the above object, the present invention provides the following technical solutions: A release auxiliary component for a pipe joint, comprising a kit and a releaser; The kit comprises an upper sleeve, a lower sleeve and a connecting piece connecting the two, and the area between the upper sleeve and the lower sleeve is separated by the connecting piece to form at least one gap; the releaser comprises an open release part and a handle part located behind the release part.

[0010] The present invention is further configured as follows: the connecting members are provided with two groups, the two groups of connecting members are symmetrically arranged, and the area between the upper sleeve and the lower sleeve is separated by the connecting members to form two symmetrical gaps.

[0011] The present invention is further configured as follows: the release portion includes two legs and a waist connecting the two legs, and a guide portion is provided at one end of the two legs away from the waist, and the thickness of the guide portion gradually increases from the end away from the waist to the other end.

[0012] The present invention is further configured such that: the two legs and the waist are integrally formed.

[0013] The present invention is further configured as follows: the upper sleeve, the lower sleeve and the connecting piece are integrally formed.

[0014] The present invention is further configured such that: the inner wall of the connecting piece is in an arc shape.

[0015] The present invention is further configured as follows: the pipe joint structure matched with the release auxiliary component comprises a main body, the inner wall of the main body is recessed to form a clearance channel 1 for the movement of the protruding part of the thruster.

[0016] The present invention is further configured as follows: a pipeline support member is arranged in the first clearance channel, the pipeline support member is divided into an upper part and a lower part which are independent of each other, and the inner wall of the upper part is recessed inward to form a second clearance channel for the protruding part of the propeller to be inserted and moved; The inner wall of the lower part is larger than the outer diameter of the pipeline, and a propeller can be inserted between the inner wall of the lower part and the outer wall of the pipeline. The bottom end of the lower part abuts against the ring gear, and the top end is connected with the upper part.

[0017] The present invention is further configured as follows: the upper portion is provided with a second notch.

[0018] In summary, the present invention has at least the following advantages: 1. A combination of a set and a releaser is provided to form a pipe release assembly, wherein the set can be sleeved on the outer wall of the pipe joint by external force. Since the outer peripheral wall of the pipe joint protrudes to form a step, the upper set and the lower set are respectively located on both sides of the protruding step, so the upper set and the lower set are limited by the step, thereby realizing the assembly of the set on the pipe joint. At this time, the upper set and the lower set are respectively located outside the end of the pipe joint and outside the peripheral side wall of the pipe joint. When it is necessary to release the pipe clamped in the pipe joint, it is only necessary to directly insert the releaser between the upper set and the pusher at the end of the pipe joint, so that the existing pusher can squeeze the ring teeth inside the pipe joint, so that the ring teeth loosen the pipe, and then the pipe can be easily taken out of the pipe joint.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0022] The present invention discloses a pipe joint and a release auxiliary component of the pipe joint, such as Figure 1 As shown, the pipe joint 3 includes a main body 31. The main body 31 can be a straight pipe, a tee, or a multi-way pipe. In the embodiment of the multi-way pipe, the kit 1 in the auxiliary assembly of the present invention can be assembled at each pipe orifice, and only one releaser 2 is required.

[0023] As Figures 1 to 3 shown, at any end of the main body 31, from the inside to the outside in sequence, there are a sealing member 32 (such as a rubber ring, for sealing. In different embodiments, one or more sealing members 32 can be provided, and multiple sealing members 32 can be stacked or separated from each other), a ring tooth 34 (for clamping the pipe 4), a pipe support member 35, and a thruster 36. The aforementioned internal members are all arranged in a ring shape at the inner wall position of the main body 31.

[0024] Among them, as Figure 3 shown, a first relief channel 312 for the protruding part 361 of the thruster 36 to move is formed by the inner wall of the main body 31 recessing, so that the protruding part 361 of the thruster 36 can penetrate into the first relief channel 312 and move a certain distance along the axial direction of the main body 31, thereby squeezing the ring tooth 34 and causing each tooth to have elastic deformation.

[0025] In addition, in order to further enhance the clamping force of the ring tooth 34 on the pipe 4, in some preferred embodiments, a pipe support member 35 is arranged in the first relief channel 312. As Figure 3 and Figure 6 shown, the pipe support member 35 is divided into an independent upper part 351 and a lower part 352. The upper part 351 and the lower part 352 are in an up-and-down structure and are in contact with each other. Among them, the upper part 351 is in a ring shape, and a second relief channel 3511 is formed by its inner wall recessing, so that the cross-section of the upper part 351 forms a stepped shape or a "C" shape for the protruding part 361 of the thruster 36 to be stuck in and move axially. In addition, a notch 3512 can be provided on the upper part 351 to provide an inner diameter change effect, so as to facilitate the assembly of the annular upper part 351 into the first relief channel 312.

[0026] In addition, the lower portion 352 is also annular, and its inner wall is slightly larger than the outer diameter of the pipe 4, so that the pusher 36 can be inserted between the inner wall of the lower portion 352 and the outer wall of the pipe 4. The lower end surface of the lower portion 352 abuts on the ring gear 34 to press the ring gear 34, and the upper end surface of the lower portion 352 protrudes outward along its radial direction to form a boss 3521, and the boss 3521 is provided with at least two, and in a preferred embodiment, it is provided with four, and the upper end surface of the boss 3521 abuts against the lower end surface of the upper portion 351, so as to transmit the force to the upper portion 351. When the pipe 4 is pulled outward, the ring gear 34 will clamp the pipe 4, and at this time, the upward force on the ring gear 34 can be transmitted not only to the pusher 36, but also to the pipeline support member 35, and is transmitted from the lower portion 352 to the upper portion 351, so as to achieve a double clamping effect on the pipe 4 inserted into the main body 31.

[0027] In some embodiments, the tooth portion of the ring tooth 34 is inclined in a direction away from the pusher 36, and the inner diameter of the ring tooth 34 (referring to the measurement of the tooth rather than the ring) is slightly smaller than the inner diameter of the pusher 36, so that after the pipe 4 is inserted into the pusher 36, the ring tooth 34 can be pushed away and the pipe 4 can be restricted from being pulled out after insertion.

[0028] When releasing the pipe, it is only necessary to push the pusher 36 toward the ring gear 34 to deform the ring gear 34 away from the pusher 36, thereby releasing the pipe 4 and taking out the pipe 4. It is worth mentioning that the main body 31 that the release auxiliary component of the present invention can adapt to is not limited by the internal components of the above-mentioned main body 31, and it can be adapted to any main body 31 with a pusher 36, such as the main body 31 without a sealing component 32 or a sealing ring support component 33, or the ring gear 34 is annular as a whole, or the sealing ring support component 33 and the main body 31 are not integrally formed (that is, the sealing ring support component 33 and the main body 31 are separable), and the release auxiliary component of the present invention can also realize the release of the pipe 4.

[0029] In some embodiments, Figure 1 and Figure 3 As shown, the pipe joint release auxiliary assembly includes a set 1 and a releaser 2, wherein the material of the set 1 is not limited, and can be metal, plastic or other materials with a certain hardness. The set 1 includes an upper set 11, a lower set 12 and a connecting piece 13 connecting the two, wherein the upper set 11 and the lower set 12 and the connecting piece 13 are preferably integrally formed. The upper set 11 in the present invention is annular, and the lower set 12 is preferably annular (such as Figure 1 As shown), the area between the upper sleeve 11 and the lower sleeve 12 is divided by the connecting member 13 to form at least one gap 14. Preferably, the connecting member 13 is provided with two groups, and the two groups of connecting members 13 are symmetrically arranged. The inner wall of the connecting member 13 is preferably in the shape of an arc surface. The area between the upper sleeve 11 and the lower sleeve 12 is divided by the connecting member 13 to form two symmetrical gaps 14, and the gap 14 is used for the front end of the releaser 2 to be inserted.

[0030] like Figure 3 As shown, after the set 1 is sleeved on the outer wall of the pipe joint 3, the upper sleeve 11 and the lower sleeve 12 are respectively located outside the end of the pipe joint 3 and outside the peripheral side wall of the pipe joint 3. It is worth mentioning that the pipe joint release auxiliary component of the present invention requires that the peripheral wall of either end of the main body 31 of the pipe joint 3 protrudes to form a step 311, and the peripheral side surface of the step 311 near the end of the opening of the main body 31 is inclined, so that the lower sleeve 12 can transition and be stuck in the other end of the step 311, so that the lower sleeve 12 is limited by the step 311 and will not fall off the pipe joint 3.

[0031] To achieve the assembly effect of the above-mentioned set 1, in some embodiments, the structure of the lower set 12 can also be a latching tooth structure (such as Figure 5 As shown), the latch teeth have at least two, and setting it as a latch tooth structure can also be limited by the step 311 at the step 311, thereby avoiding the problem of the kit 1 falling off from the pipe connector 3.

[0032] In addition, the inner diameter of the upper sleeve 11 can be equal to the inner diameter of the pusher 36. In a preferred embodiment, the inner and outer diameters of the pusher 36 are preferably between the inner and outer diameters of the pusher 36. After the sleeve 1 is pressed down, it can abut against the end wall of the pusher 36, thereby squeezing the pusher 36, realizing the tooth deformation of the ring gear 34 and releasing the pipe 4. It is worth mentioning that this squeezing method is a manual squeezing release method, which is only one of the methods for releasing the pipe 4. Another method can be achieved by inserting the releaser 2.

[0033] In some embodiments, Figure 4 As shown, the releaser 2 includes an open release portion 21 (located at the front end) and a handle portion 22 located behind the release portion 21. The release portion 21 includes two legs 211 and a waist 212 connecting the two legs 211. The two legs 211 and the waist 212 are preferably integrally formed. A guide portion 2111 is provided at one end of the two legs 211 away from the waist 212. The thickness of the guide portion 2111 gradually increases from the end away from the waist 212 to the other end. It is worth mentioning that in some embodiments, the thickness of the legs 211 can also be changed, so as to form a gradually transitional shape with the guide portion 2111. At this time, there is no obvious boundary between the legs 211 and the guide portion 2111.

[0034] like Figure 3As shown, when the pipe 4 clamped in the pipe joint 3 needs to be released, it is only necessary to insert the releaser 2 into the gap 141 between the upper sleeve 11 and the pusher 36. It is worth noting that the gap 141 should be smaller than the thickness of the leg 211 (when the pusher 36 is not squeezed by the releaser 2) so that the pusher 36 can be squeezed when the releaser 2 is inserted, thereby allowing the ring gear 34 to loosen the pipe 4 and easily remove the pipe 4 from the pipe joint 3.

[0035] Finally, if Figure 3 As shown, the kit 1 provided by the present invention can not only move axially on the pipe joint 3, but also rotate on the pipe joint 3 when the connecting piece 13 is long, so as to rotate the notch 14 to an angle and height that is convenient for inserting the releaser 2, so as to overcome the problem of the pipe joint 3 being difficult to operate when it is installed in a corner or blocked by objects.

[0036] The working process and beneficial effects of the present invention are as follows: the kit 1 is directly sleeved on the outer wall of the pipe joint 3 by external force and is sold as a whole with the pipe joint 3. At this time, the upper sleeve 11 and the lower sleeve 12 are respectively located on both sides of the protruding step 311, and the upper sleeve 11 and the lower sleeve 12 are respectively located outside the end of the pipe joint 3 and outside the peripheral side wall of the pipe joint 3.

[0037] When the pipe 4 clamped in the pipe joint 3 needs to be released, the pipe 4 can be released directly by manually pressing the kit 1, or the releaser 2 can be inserted between the upper sleeve 11 and the pusher 36 at the end of the pipe joint 3, so that the pusher 36 squeezes the ring gear 34 inside the pipe joint 3, thereby causing the ring gear 34 to loosen the pipe 4, and then the pipe 4 can be easily taken out of the pipe joint 3.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
