Description

Technical Field

[0001] This utility belongs to the field of piping, and more specifically it relates to a pipe fitting and a pipe fitting release aid component. Background Technology

[0002] In modern architecture, industrial production, and daily life, piping systems play a crucial role in transporting fluids, including liquids, gases, and even plasmas. From domestic water systems to complex networks in schools, medical facilities, and commercial buildings, piping systems ensure the efficient circulation and utilization of various fluids such as hot and cold water, air, glycol, compressed air, inert gases, chemicals, wastewater, cooling media, and coatings. Piping materials are diverse, including copper, stainless steel, CPVC (chlorinated polyvinyl chloride), and PEX (cross-linked polyethylene), with the choice often based on fluid properties, pressure requirements, and cost considerations. In this discussion, the term "piping" or "piping system" refers broadly to the overall system encompassing pipes, conduits, piping components, and their combinations.

[0003] Piping connections, as the foundation for constructing complex piping systems, must flexibly adapt to the needs of different layouts and directional changes. By employing various fittings and valves, such as elbows, tees, connectors, and ball valves and gate valves for size conversion, terminal connections, and flow control, piping systems can be assembled efficiently.

[0004] Historically, pipe connections have primarily relied on welding and brazing techniques. While effective, these traditional methods present numerous challenges. Brazing requires extensive preparation, such as cleaning the pipe ends and applying flux, as well as specialized skills and protective equipment. The process is time-consuming and carries safety risks. Furthermore, brazing materials (such as solder and welding torches) and subsequent inspections are expensive and not suitable for all material combinations.

[0005] In recent years, push-fit technology has gradually become a new favorite for pipe connections due to its simplicity, speed, and low material requirements. This technology requires only pipes, quick-connect fittings, deburring tools, and a cutter to complete the installation, greatly simplifying the operation process. The core of the push-fit connection lies in the ring teeth (clamps, clamping rings), whose design automatically clamps the pipe upon insertion, forming a reliable seal and connection without the need for additional tools or welding.

[0006] However, early push-fit connection technologies also had shortcomings. For example, plastic clamping ring supports were prone to failure under tensile forces, requiring additional embossing, gluing, or threaded caps to secure the ring teeth. This not only increased manufacturing costs but also reduced production efficiency. The threaded cap method also needed to consider the cost of thread processing and the use of sealants, while the embossing method could result in the ring teeth being permanently fixed, making them difficult to repair or replace.

[0007] Furthermore, traditional connection technologies are often limited to connections between similar materials, lacking effective solutions for combinations of copper with different materials such as CPVC, PEX, and stainless steel. When problems arise, the entire component usually needs to be replaced rather than repairing the faulty part, which not only wastes resources but also increases maintenance costs. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model 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 objectives, this utility model provides the following technical solution:

[0010] A release aid assembly for a pipe fitting includes a kit and a release device;

[0011] The kit includes an upper sleeve, a lower sleeve, and a connector connecting the two, wherein the area between the upper sleeve and the lower sleeve is divided by the connector to form at least one notch; the release device includes an open release part and a handle part located behind the release part.

[0012] The present invention is further configured such that: the connector is provided in two sets, the two sets of connectors are symmetrically arranged, and the area between the upper sleeve and the lower sleeve is separated by the connector to form two symmetrical gaps.

[0013] The present invention is further configured such that: the release part includes two legs and a waist connecting the two legs, and a guide part is provided at the end of the two legs away from the waist, and the thickness of the guide part gradually increases from the end away from the waist to the other end.

[0014] This utility model is further configured such that the two legs and waist are integrally formed.

[0015] This utility model is further configured such that the upper sleeve, the lower sleeve, and the connecting piece are integrally formed.

[0016] The present invention is further configured such that the inner wall of the connector is arc-shaped.

[0017] This utility model is further configured as follows: a pipe joint structure that cooperates with the release auxiliary component, including a body, wherein the inner wall of the body is recessed to form a clearance channel for the movement of the protruding portion of the thruster.

[0018] The present invention is further configured such that: a pipeline support component is provided inside the first clearance channel, the pipeline support component is divided into an independent upper part and a lower part, and the inner wall of the upper part is recessed inward to form a second clearance channel for the protruding part of the thruster to be inserted and moved;

[0019] The lower inner wall is larger than the outer diameter of the pipe, and a pusher can be inserted between the lower inner wall and the outer wall of the pipe. The bottom end of the lower part abuts against the ring tooth, and the top end connects with the upper part.

[0020] This utility model is further configured such that the upper part has a notch two.

[0021] In summary, this utility model has at least the following advantages:

[0022] 1. An assembly for releasing the pipe is formed by setting up a kit and a release device. The kit can be fitted onto 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 and lower sleeves are located on opposite sides of the protruding step, thus limiting their position and allowing the kit to be assembled on the pipe joint. At this point, the upper and lower sleeves are located outside the end of the pipe joint and outside the peripheral wall of the pipe joint, respectively. When it is necessary to release the pipe clamped inside the pipe joint, simply insert the release device directly between the upper sleeve and the pusher at the end of the pipe joint. This causes the pusher to compress the ring teeth inside the pipe joint, thereby loosening the ring teeth and allowing the pipe to be easily removed from the pipe joint. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model discloses a pipe joint and a release auxiliary component for the pipe joint, such as... Figure 1 As shown, the pipe joint 3 includes a body 31, which 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 component of this utility model can be assembled at each pipe opening, while only one releaser 2 is needed.

[0032] like Figures 1 to 3 As shown, at any end of the main body 31, there are, from the inside out, a sealing member 32 (such as a rubber ring, used for sealing; in different embodiments, one or more sealing members 32 may be provided, and multiple sealing members 32 may be stacked or separated), a ring tooth 34 (used to clamp the pipe 4), a pipe support member 35, and a pusher 36. The aforementioned internal components are all arranged in a ring on the inner wall of the main body 31.

[0033] Among them, such as Figure 3 As shown, the inner wall of the main body 31 is recessed to form a relief channel 312 for the movement of the protruding part 361 of the thruster 36, so that the protruding part 361 of the thruster 36 can enter the 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 undergo elastic deformation.

[0034] Furthermore, 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 provided within the clearance channel 312, such as... Figure 3 and Figure 6As shown, the pipeline support component 35 is divided into an independent upper part 351 and a lower part 352, which are vertically connected and abut against each other. The upper part 351 is annular, with its inner wall recessed to form a second clearance channel 3511, thus creating a stepped or "U"-shaped cross-section for the protruding portion 361 of the pusher 36 to engage and move axially. Furthermore, a second notch 3512 can be provided on the upper part 351 to allow for changes in inner diameter, facilitating the assembly of the annular upper part 351 into the first clearance channel 312.

[0035] Furthermore, the lower part 352 is also annular, with its inner wall slightly larger than the outer diameter of the pipe 4, allowing the pusher 36 to be inserted between the inner wall of the lower part 352 and the outer wall of the pipe 4. The lower end face of the lower part 352 abuts against the ring tooth 34 to press the ring tooth 34, while the upper end face of the lower part 352 protrudes radially outward to form a boss 3521. At least two bosses 3521 are provided, and in a preferred embodiment, four are provided. The upper end face of the boss 3521 abuts against the lower end face of the upper part 351, thereby transmitting the force to the upper part 351. When the pipe 4 is pulled outward, the ring tooth 34 clamps the pipe 4. At this time, the upward force on the ring tooth 34 can be transmitted not only to the pusher 36 but also to the pipe support member 35, and from the lower part 352 to the upper part 351, thereby achieving a double clamping effect on the pipe 4 inserted into the body 31.

[0036] In some embodiments, the teeth of the ring tooth 34 are inclined away from the pusher 36, and the inner diameter of the ring tooth 34 (referring to the measured teeth rather than the ring) is slightly smaller than the inner diameter of the pusher 36, so that the ring tooth 34 can be pushed away after the pipe 4 is inserted into the pusher 36 and the pipe 4 can be restricted from being pulled out after insertion.

[0037] When releasing the pipe, simply push the pusher 36 towards the ring tooth 34 to deform the ring tooth 34 away from the pusher 36, thereby releasing the pipe 4 and allowing it to be removed. It is worth noting that the main body 31 to which this release auxiliary component can be adapted is not limited to the internal components of the main body 31 described above. It can be adapted to any main body 31 with a pusher 36, such as a main body 31 without a sealing component 32 or a sealing ring support component 33, or where the ring tooth 34 is entirely ring-shaped, or where the sealing ring support component 33 is not integrally formed with the main body 31 (i.e., the sealing ring support component 33 can be separated from the main body 31). This release auxiliary component can still achieve the release of the pipe 4.

[0038] In some embodiments, such as Figure 1 and Figure 3As shown, the pipe joint release auxiliary assembly includes a kit 1 and a releaser 2. The material of the kit 1 is not limited; it can be metal, plastic, or other materials with a certain degree of hardness. The kit 1 includes an upper sleeve 11, a lower sleeve 12, and a connector 13 connecting the two. Preferably, the upper sleeve 11, lower sleeve 12, and connector 13 are integrally formed. In this utility model, the upper sleeve 11 is annular, and the lower sleeve 12 is preferably annular (e.g., ...). Figure 1 As shown), the area between the upper sleeve 11 and the lower sleeve 12 is divided by the connector 13 to form at least one notch 14. Preferably, there are two sets of connectors 13, which are symmetrically arranged. The inner wall of the connector 13 is preferably arc-shaped. The area between the upper sleeve 11 and the lower sleeve 12 is divided by the connector 13 to form two symmetrical notches 14. The notch 14 is used for the insertion of the front end of the releaser 2.

[0039] like Figure 3 As shown, after kit 1 is fitted onto the outer wall of pipe joint 3, the upper sleeve 11 and the lower sleeve 12 are located outside the end of pipe joint 3 and outside the peripheral wall of pipe joint 3, respectively. It is worth mentioning that the pipe joint release auxiliary assembly of this utility requires that the outer peripheral wall of either end of the main body 31 of pipe joint 3 protrude to form a step 311. The peripheral side of the step 311 near the opening of the main body 31 is inclined so that the lower sleeve 12 can move and transition and get into the other end of the step 311, thereby limiting the lower sleeve 12 by the step 311 and preventing it from falling off the pipe joint 3.

[0040] To achieve the assembly effect of the above-mentioned kit 1, in some embodiments, the structure of the lower sleeve 12 can also be a toothed structure (such as...). Figure 5 As shown), the locking teeth have at least two, and setting them as a locking tooth structure can also be limited by the step 311 at the step 311, thereby preventing the kit 1 from falling off the pipe joint 3.

[0041] Furthermore, 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 those 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 and realizing the deformation of the ring tooth 34 and the release of the pipe 4. It is worth mentioning that this squeezing method is a manual squeezing release method. The manual squeezing release method is only one way to release the pipe 4. Another way is to insert the release device 2.

[0042] In some embodiments, such as Figure 4As shown, the release device 2 includes an open-ended release section 21 (located at the front end) and a handle section 22 located behind the release section 21. The release section 21 includes two legs 211 and a waist section 212 connecting the two legs 211. The two legs 211 and the waist section 212 are preferably integrally formed. A guide section 2111 is provided at the end of the two legs 211 away from the waist section 212. The thickness of the guide section 2111 gradually increases from the end away from the waist section 212 to the other end. It is worth mentioning that in some embodiments, the thickness of the legs 211 can also vary, thus forming a gradual transition shape with the guide section 2111, in which case there is no clear boundary between the legs 211 and the guide section 2111.

[0043] like Figure 3 As shown, when it is necessary to release the pipe 4 clamped in the pipe joint 3, simply insert the release device 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 release device 2) so that the pusher 36 can be squeezed when the release device 2 is inserted, thereby causing the ring tooth 34 to loosen the pipe 4 and easily remove the pipe 4 from the pipe joint 3.

[0044] Finally, as Figure 3 As shown, the kit 1 provided by this utility model, when the connector 13 is long, can not only move axially on the pipe joint 3, but also rotate on the pipe joint 3, so as to rotate the notch 14 to an angle and height that facilitates the insertion of the release device 2, thereby overcoming the problem of the pipe joint 3 being difficult to operate when it is installed in a corner or blocked by objects.

[0045] The working process and beneficial effects of this utility are as follows: The kit 1 is directly fitted onto 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 located on both sides of the protruding step 311, and the upper sleeve 11 and the lower sleeve 12 are located outside the end of the pipe joint 3 and outside the peripheral wall of the pipe joint 3, respectively.

[0046] When it is necessary to release the pipe 4 clamped inside the pipe joint 3, the pipe 4 can be released directly by manually pressing the kit 1, or the release device 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 teeth 34 inside the pipe joint 3, thereby causing the ring teeth 34 to loosen the pipe 4, and then the pipe 4 can be easily removed from the pipe joint 3.

[0047] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of this utility model should be included within the protection scope of this utility model.
