Description

Technical Field

[0001] This utility model relates to the field of overflow pipe joint technology, specifically a high-temperature resistant automotive overflow pipe joint. Background Technology

[0002] Automotive overflow pipe joints must meet core requirements such as high temperature resistance, corrosion resistance, and reliable sealing. Their material selection and structural design directly affect the stability of key components such as the automotive cooling system and fuel system.

[0003] In existing technologies, the most common high-temperature resistant automotive overflow hose connectors are generally made of ethylene propylene diene monomer (EPDM) rubber. Their advantage lies in their high-temperature resistance. They are used to connect the upper and lower water pipes of the radiator and the overflow hose of the auxiliary water tank. When the engine coolant temperature rises, the liquid volume expands, and the pressure in the system rises sharply, the excess liquid is guided to the auxiliary water tank or compensating water tank through the automotive overflow hose connector, thereby releasing the pressure and protecting the system safety.

[0004] In current technology, the conventional method for securing automotive overflow pipe fittings is to use clamps to tighten the hose and fitting. However, this traditional connection method has significant drawbacks, primarily its weak resistance to pull-out. Although it can withstand the vibrations and impacts generated during vehicle operation, it is prone to loosening during vehicle maintenance or other operations if the connecting hose is subjected to external force. Furthermore, such loosening is often difficult to detect in a timely manner. Therefore, an improved high-temperature resistant automotive overflow pipe fitting is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant automotive overflow pipe connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant automotive overflow pipe connector, comprising a water tank body, an upper connection port at the upper surface of the water tank body, a lower connection port at the lower end of the water tank body, an overflow chamber at the top of the water tank body, a connector body on one side of the overflow chamber, an overflow hose sleeved on the outer surface of the connector body, and a fixing mechanism for fixing the overflow hose between the overflow hose and the connector body, the fixing mechanism comprising a clamping strap, a raised ring, a fixing ring, and a compression sleeve, a clamping strap sleeved on the outer side of the overflow hose, a raised ring on one side of the connector body, a fixing ring fixedly disposed on one side of the raised ring on the surface of the connector body, and a compression sleeve screwed into the outer surface of the fixing ring.

[0007] Preferably, the inner sidewall of the extrusion sleeve is chamfered. The chamfer makes it easier for the extrusion sleeve to squeeze the overflow hose when it moves towards the protruding ring, so that the overflow hose is tightly attached to the outer surface of the protruding ring. In this way, the extrusion sleeve and the protruding ring use huge extrusion force to firmly squeeze and fix the overflow hose together, which can significantly improve the anti-pull-out performance of the overflow hose and prevent the hose from loosening unexpectedly due to pull-out.

[0008] Preferably, a plurality of heat dissipation fins are uniformly fixedly arranged on the outer surface of the water tank body, and mounting parts are fixedly arranged on both sides of the surface of the water tank body. The heat dissipation fins can ensure the heat dissipation effect of the water tank body, while the mounting parts can conveniently fix the water tank body to the target position.

[0009] Preferably, one end of the cable tie is provided with a tightening mechanism, which includes a connecting chamber, a screw, and a reducing section. The connecting chamber is fixedly provided at one end of the cable tie, and a screw is movably screwed into one side of the connecting chamber. The reducing section is fixedly provided at one end of the screw, and the other end of the cable tie is inserted into the connecting chamber at the lower end of the screw and the reducing section. This allows the reducing section and the cable tie to squeeze each other when the screw is tightened, thus fixing the cable tie. Traditional cable ties are inconvenient to disassemble after fixing, or workers may cut them off. After disassembly, they are no longer needed, which is not only wasteful, but also requires scissors to be inserted between the cable tie and the overflow hose each time, which may damage the overflow hose. The cable tie structure disclosed in this device uses the squeezing force of the reducing section to compress the rubber cable tie after the screw is turned, ensuring the cable tie is fixed. When loosening, only the screw needs to be loosened. Thus, it is more convenient to fix and release the cable tie part of this device.

[0010] Preferably, a rotating head is fixedly provided at one end of the variable diameter section, which allows workers to easily rotate the screw using a wrench or screwdriver.

[0011] Preferably, the outer surface of the connector body is provided with a groove, which can tighten the overflow hose when the cable tie is tightened, so that the overflow hose is embedded in the groove, thereby further improving the fixing effect between the overflow hose and the connector body.

[0012] Preferably, the outer surface of the tightening band is evenly provided with several friction grooves. The friction grooves can increase the squeezing friction between the variable diameter section and the tightening band, thereby effectively preventing the band from loosening. At the same time, the friction of the variable diameter section squeezing the band is used to fix the band and prevent it from loosening. The friction can also prevent the variable diameter section and the screw from being reversed, which could cause the screw to loosen.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. After the initial fixation with the clamping strap, the present invention rotates the compression sleeve, causing it to move towards the protruding ring under the action of the thread. In this way, the compression sleeve can compress the overflow hose, making the overflow hose tightly adhere to the outer surface of the protruding ring. Thus, the compression sleeve and the protruding ring use huge compressive force to firmly compress and fix the overflow hose, which can significantly improve the anti-pull-out performance of the overflow hose and prevent the hose from loosening unexpectedly due to pull-out.

[0015] 2. The cable tie structure disclosed in this utility model utilizes the squeezing force of the variable diameter section to compress the rubber cable tie after the screw is rotated, ensuring the cable tie is fixed. When it becomes loose, simply loosen the screw. Thus, it is relatively convenient to fix and release the cable tie part of this device.

[0016] 3. The screw and compression sleeve of this utility model, while compressing and fixing the clamping band and overflow hose, also restrict the rotation of the screw and compression sleeve by the corresponding friction, so as to ensure that the screw and compression sleeve are not easily loosened by the vibration of the vehicle when there is no human operation, thereby improving the use effect of this device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a high-temperature resistant automotive overflow pipe connector, including a water tank body 1. The upper surface of the water tank body 1 is provided with an upper connection port 2, the lower end is provided with a lower connection port 3, and the top is provided with an overflow chamber 4. A connector body 5 is installed on one side of the overflow chamber 4, and an overflow hose 6 is sleeved on the outside of the connector body 5, and the two are securely connected by a fixing mechanism. This fixing mechanism consists of a clamping strap 7, a raised ring 8, a fixing ring 9, and a compression sleeve 10. The clamping strap 7 is sleeved on the outside of the overflow hose 6, the surface of the connector body 5 is provided with a raised ring 8, and a fixing ring 9 is fixed on one side of the surface of the connector body 5. The outside of the fixing ring 9 is movably connected to the compression sleeve 10 by a thread.

[0025] The inner sidewall of the compression sleeve 10 is chamfered 11. This design allows the compression sleeve 10 to more smoothly compress the overflow hose 6 when it moves toward the protruding ring 8, so that it fits tightly against the outer surface of the protruding ring 8, further enhancing the fixing effect and improving the pull-out resistance.

[0026] The outer surface of the water tank body 1 is evenly distributed with several heat dissipation fins 12 to ensure the heat dissipation effect of the water tank. At the same time, mounting parts 13 are provided on both sides of the surface of the water tank body 1 to facilitate the stable installation of the water tank body 1 in the target position.

[0027] The cable tie 7 has a tightening mechanism at one end, which includes a connecting chamber 14, a screw 19, and a reducing section 15. The connecting chamber 14 is fixed to one end of the cable tie 7, and the screw 19 is threadedly connected to one side of the connecting chamber 14. One end of the screw 19 has a reducing section 15. The other end of the cable tie 7 passes inside the connecting chamber 14, located below the screw 19 and the reducing section 15. When the screw 19 is tightened, the reducing section 15 and the cable tie 7 are pressed together, achieving a secure fit. This design solves the problem of inconvenient disassembly or the need to cut traditional cable ties, avoiding waste and potential damage to the overflow hose 6 from scissors. The cable tie structure of this device uses the rotation of the screw 19 to cause the reducing section 15 to compress the rubber cable tie, ensuring a secure fit. Loosening the cable tie only requires loosening the screw 19, making disassembly convenient.

[0028] One end of the reducing section 15 is equipped with a rotating head 16, which allows workers to easily turn the screw 19 using a wrench or screwdriver. A groove 17 is formed on the outer surface of the connector body 5. When the cable tie 7 is tightened, the overflow hose 6 can be embedded in the groove 17, further improving the fixing effect. Several friction grooves 18 are evenly distributed on the outer surface of the cable tie 7 to increase the compressive friction between the reducing section 15 and the cable tie 7, preventing the cable tie from loosening and also preventing the screw 19 from reversing and loosening.

[0029] Working principle: When using this device, the connector body 5 and the overflow hose 6 are initially secured together using the clamping strap 7. To tighten, insert the other end of the clamping strap 7 into the connecting chamber 14, without first tightening the screw 19. Pull the clamping strap 7 tight before tightening the screw 19. After the screw 19 is tightened, the reducing section 15 compresses the rubber clamping strap, ensuring a secure hold. To loosen, simply loosen the screw 19; disassembly is convenient.

[0030] After the clamping strap 7 is initially secured, the compression sleeve 10 is rotated, causing it to move closer to the raised ring 8 under the action of the threads. The compression sleeve 10 compresses the overflow hose 6, making it tightly adhere to the outer surface of the raised ring 8. The enormous compressive force generated by the compression sleeve 10 and the raised ring 8 firmly compresses and fixes the overflow hose 6, significantly improving its anti-pull-out performance and preventing the hose from accidentally loosening due to pull-out.

[0031] Meanwhile, the friction generated by the screw 19 and the compression sleeve 10 of this device while squeezing and fixing the clamping strap 7 and the overflow hose 6 also restricts the rotation of the screw 19 and the compression sleeve 10, ensuring that the screw 19 and the compression sleeve 10 are not easy to loosen by the vibration of the vehicle driving alone without human operation, thereby improving the use effect of this device.
