Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and more specifically, to a pipe clamp. Background Technology
[0002] Due to space constraints and the need for convenient installation of air conditioning pipes, existing automotive air conditioning systems sometimes extend the inlet and outlet positions of the condenser assembly a certain distance beyond the heat exchanger manifold. In this case, jumpers are needed to connect the condenser inlet and outlet pressure plates to the manifold. Because the connecting jumper pipes are relatively long, fixing clamps are used to connect the inlet and outlet pipes to improve strength and prevent deformation. Currently, similar solutions on the market mostly use aluminum fixing clamps, which are welded to the inlet and outlet pipes respectively.
[0003] Currently, the fixed pipe clamps connected by welding have the following disadvantages:
[0004] 1. The welding method increases the number of welding points on the condenser, leading to an increased risk of leakage;
[0005] 2. Currently, fixed pipe clamps, inlet and outlet pressure plates, and jumpers are supplied by suppliers as components, requiring suppliers to have certain welding and airtightness testing capabilities, which indirectly increases the cost of parts;
[0006] 3. It is impossible to guarantee that all pipe clamps are welded well and leak-free. 100% inspection cannot be carried out in the incoming process, which will result in some poorly welded parts entering the final assembly process, indirectly increasing the workload of helium testing of the assembly.
[0007] 4. The joint assembly for fixing the pipe clamp by welding cannot be brazed together with the core and can only be installed by manual spot welding after the furnace.
[0008] 5. Welded pipe clamps are not conducive to improving the product's environmental protection aspects. Utility Model Content
[0009] The purpose of this utility model includes, for example, providing a fixing pipe clamp that can be detachably connected to the jumper pipe by a snap-fit method.
[0010] The embodiments of this utility model can be implemented as follows:
[0011] In a first aspect, this utility model provides a pipe clamp capable of clamping jump pipes, comprising:
[0012] A connecting part and at least two retaining rings; adjacent retaining rings are connected by the connecting part;
[0013] The retaining ring includes an annular ring body and a plurality of anti-slip teeth disposed on the inner wall of the ring body; the anti-slip teeth all extend toward the center of the ring body; the ring body has a through-hole provided on the wall surface;
[0014] In each retaining ring, along the radial direction of the retaining ring, the ends of the anti-slip teeth away from the ring body collectively enclose a circular retaining space;
[0015] The jump tube can pass through the bayonet and be embedded in the holding space.
[0016] In an optional embodiment, the inner diameter of the holding space is less than or equal to the outer diameter of the jump tube.
[0017] In an optional implementation, the width of the bayonet is smaller than the outer diameter of the jump tube.
[0018] In an optional embodiment, the connecting part, the ring body, and the anti-slip teeth are integrally formed.
[0019] In an optional embodiment, the jumper clamp is made of plastic.
[0020] In an optional embodiment, the jumper fixing clamp is made of PA66 material.
[0021] In an optional embodiment, the jumper pipe fixing clamp is manufactured using an injection molding process.
[0022] In an optional embodiment, the connecting portion is provided with a through hole that extends along the axis of the retaining ring.
[0023] In an optional embodiment, the connecting portion includes a first plate and a second plate, the first plate and the second plate maintaining a distance from each other so that the first plate and the second plate enclose a through hole.
[0024] In an optional embodiment, along the length of the first plate, one end of the first plate is tangent to the outer wall of a retaining ring, and the other end of the first plate is tangent to the outer wall of an adjacent retaining ring; and the first plate is located on the side away from the latch.
[0025] The beneficial effects of this utility model embodiment include, for example:
[0026] The fixed pipe clamp of this solution includes a connecting part and at least two retaining rings; adjacent retaining rings are connected by the connecting part. Because each retaining ring can engage with its corresponding jumper pipe, this facilitates the detachable connection of multiple jumper pipes. Furthermore, the inner wall of the retaining ring is provided with multiple anti-slip teeth, which together form a circular holding space. The jumper pipe passes through the retaining slot and is embedded in the holding space, thus achieving a detachable engagement between the jumper pipe and the retaining ring. Compared to the existing technology where the fixed pipe clamp is welded to different jumper pipes separately, the method of engaging the fixed pipe clamp with the jumper pipe through the retaining ring simplifies the connection between the fixed pipe clamp and the jumper pipe, saves time and effort during assembly, is easy to install and remove, facilitates subsequent pipeline maintenance, and avoids damage to the pipeline during welding. At the same time, this connection method is also more environmentally friendly, thus resulting in significant economic benefits. Attached Figure Description

[0038] Please refer to Figure 1 This embodiment provides a fixing clamp 10 capable of clamping the jumper pipe 21, including:
[0039] A connecting portion 100 and at least two retaining rings 200; adjacent retaining rings 200 are connected by the connecting portion 100;
[0040] The retaining ring 200 includes an annular ring body 210 and a plurality of anti-slip teeth 220 disposed on the inner wall of the ring body 210; the anti-slip teeth 220 all extend toward the center of the ring body 210; the ring body 210 has a through retaining opening 211 disposed on the wall surface;
[0041] In each retaining ring 200, along the radial direction of the retaining ring 200, the anti-slip teeth 220, at the ends away from the ring body 210, together enclose a circular retaining space 201.
[0042] The jump tube 21 can pass through the bayonet 211 and be embedded in the holding space 201.
[0043] The fixed pipe clamp 10 of this solution includes a connecting part 100 and at least two retaining rings 200; adjacent retaining rings 200 are connected by the connecting part 100. Since each retaining ring 200 can engage with a corresponding jumper pipe 21, this facilitates the detachable connection of multiple jumper pipes 21. Furthermore, the inner wall of the retaining ring 200 is provided with multiple anti-slip teeth 220, which together form a circular holding space 201. The jumper pipe 21 passes through the retaining opening 211 and is embedded in the holding space 201, thus achieving a detachable engagement between the jumper pipe 21 and the retaining ring 200. Compared to the existing method of welding the fixed pipe clamp 10 to different jumper pipes 21 separately, the method of engaging the jumper pipe 21 with the retaining ring 200 simplifies the connection between the fixed pipe clamp 10 and the jumper pipe 21, saves time and effort in the assembly process, facilitates easy installation and removal, is beneficial for subsequent pipeline maintenance, and avoids damage to the pipeline during the welding process; at the same time, this connection method is also more environmentally friendly, thus resulting in significant economic benefits.
[0044] Please continue reading. Figure 1 , Figure 2 and Figure 3 To understand more structural details of the fixing clamp 10, the figure shows that in this embodiment, the fixing clamp 10 includes two retaining rings 200, which are connected by a connecting part 100. Furthermore, the two retaining rings 200 are respectively connected to two jump pipes 21, which are an inlet pipe and an outlet pipe, respectively. The anti-slip teeth 220 have an isosceles trapezoidal cross-section.
[0045] As can be seen from the figure, there is a gap between adjacent anti-slip teeth 220 along the circumferential direction of the retaining ring 200. This provides a space 222 for the anti-slip teeth 220 to engage with the outer wall of the jump tube 21, ensuring that each anti-slip tooth 220 can be stably held on the outer wall of the jump tube 21.
[0046] Optionally, the ring 210 of the retaining ring 200 is a hollow cylinder. It is easy to understand that in other embodiments of this utility model, the ring 210 can also be polygonal or elliptical, as long as the retaining space 201 is a circle that matches the jump tube 21.
[0047] It should be noted that in this embodiment, the annular surfaces of adjacent retaining rings 200 are all located on the same plane, that is, the axis lines of adjacent retaining rings 200 remain parallel, thus ensuring that two adjacent jump tubes 21 remain parallel. It is understood that in other embodiments of this utility model, adjacent retaining rings 200 may maintain an included angle to accommodate jump tubes 21 with different installation angles.
[0048] In an optional embodiment, the inner diameter of the retaining space 201 is less than or equal to the outer diameter of the jump tube 21. That is, the jump tube 21 and the retaining ring 200 are interference-fitted, thereby ensuring the stability of the connection between the jump tube 21 and the retaining ring 200.
[0049] In an optional embodiment, the width of the bayonet 211 is smaller than the outer diameter of the jumper tube 21. This bayonet 211 design has an anti-reverse function, thus preventing the jumper tube 21 from easily dislodging from the bayonet 211, thereby ensuring the stability of the connection between the jumper tube 21 and the retaining ring 200. It also ensures that the tube clamp position will not undergo relative displacement due to vibration.
[0050] Furthermore, anti-slip teeth 220 are provided on the edges of the bayonet 211. This further ensures the tightness of the connection between the bayonet 211 and the jumper tube 21, preventing the jumper tube 21 from coming out of the bayonet 211.
[0051] In an optional embodiment, the connecting part 100, the ring body 210, and the anti-slip teeth 220 are integrally formed. That is, the jumper 21 fixing clamp 10 is an integrally formed structure. This arrangement simplifies manufacturing and improves production efficiency.
[0052] In an optional embodiment, the clamp 10 for fixing the jumper tube 21 is made of plastic. The plastic material is flexible, allowing the anti-slip teeth 220 to connect more tightly to the outer wall of the jumper tube 21. Furthermore, adjacent anti-slip teeth 220 can move elastically within the movement space 222 to ensure secure clamping to the outer wall of the jumper tube 21.
[0053] In an optional embodiment, the material of the fixing clamp 10 for the jumper 21 is PA66. PA66 plastic raw material is a translucent, white or black crystalline polymeric polyamide resin, with the English name polyamide, abbreviated as PA. Commonly known as nylon, it is a general term for polymers whose macromolecular main chain repeating units contain amide groups. PA66 material has the advantages of high rigidity and heat resistance, thus ensuring the structural stability of the fixing clamp 10.
[0054] In an optional embodiment, the jumper 21 fixing clamp 10 is manufactured using an injection molding process.
[0055] In an optional embodiment, the connecting portion 100 is provided with a through hole 101, which extends along the axial direction of the retaining ring 200. The through hole 101 can reduce the overall weight of the fixing pipe clamp 10 and also save on the processing and manufacturing costs of the fixing pipe clamp 10.
[0056] In an optional embodiment, the connecting portion 100 includes a first plate 110 and a second plate 120, which are spaced apart to form a through hole 101. That is, the first plate 110 and the second plate 120 serve as a connecting structure for adjacent retaining rings 200. Because the plastic plates are flexible, this arrangement ensures that when the fixing clamp 10 is connected to the two jump pipes 21 respectively, the possibility of breakage due to pulling is reduced.
[0057] In an optional embodiment, along the length of the first plate 110, one end of the first plate 110 is tangent to the outer wall of a retaining ring 200, and the other end of the first plate 110 is tangent to the outer wall of an adjacent retaining ring 200; and the first plate 110 is located on the side away from the latch 211. Further, the second plate 120 is located at the center of the annular surface of the retaining ring 200.
[0058] By having the first plate 110 tangentially engage with the adjacent retaining rings 200, the connection stability between the connecting part 100 and the retaining rings 200 can be ensured. At the same time, the weight of the connecting part 100 can also be reduced.
[0059] In summary, this utility model embodiment provides a fixing clamp 10, which has at least the following advantages:
[0060] 1. Reduced manufacturing difficulties for component suppliers;
[0061] 2. The inlet and outlet connector components can be directly brazed in the furnace along with the core, eliminating the need for subsequent manual spot welding installation;
[0062] 3. It can be quickly installed manually at the furnace post-alignment station, eliminating the risk of leakage caused by welding;
[0063] 4. It enables the standardization of components.
[0064] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
