Description

Technical Field

[0001] This utility model relates to the field of automotive engine technology, and in particular to a crimping device for an automotive engine water inlet pipe connector. Background Technology

[0002] The car engine is the device that provides power to the car. It is the heart of the car and determines the car's power, economy and environmental performance. In order to control the engine temperature and prevent it from getting too cold or too hot, and to ensure that the engine works efficiently and stably, it is necessary to connect the engine to a water inlet pipe. In order to meet the sealing requirements of the engine cooling system, a water inlet pipe fitting crimping device is usually required.

[0003] The inlet pipe fitting crimping device, also known as a crimping ring or clamping ring, is a metal or plastic ring-shaped component used to fix and seal the connection between the inlet pipe and the fitting. It mainly prevents the water pipe from being tightly fixed to the fitting by crimping, prevents coolant leakage, and ensures the reliability of the connection.

[0004] Existing crimping rings are usually metal rings. However, after the metal ring is tightened at the interface between the water inlet pipe and the engine, it needs to be disassembled during maintenance, which will damage the metal ring. This makes it difficult to reuse the metal ring, thereby increasing the maintenance cost of the car engine. In addition, some crimping rings use a screw fastening method, but the screw fastening method requires the use of tools. Since the space inside the car engine compartment is small, it is inconvenient to install crimping rings and consumes installation time. Utility Model Content

[0005] The purpose of this invention is to solve the problems of conventional crimping rings being difficult to reuse and crimping rings with screw fastening being inconvenient to install in the prior art, and to propose a crimping device for automotive engine water inlet pipe joints.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crimping device for a car engine water inlet pipe joint includes an adjusting belt, a fixing block fixedly installed on the adjusting belt, a locking area formed between the fixing block and the adjusting belt, a locking tooth slidably installed on the fixing block, and locking teeth equidistantly installed on the adjusting belt to form an adjusting section. The locking tooth and the locking tooth can engage. An unlocking element is provided on the fixing block. When the locking tooth and the locking tooth engage, the unlocking element locks the adjusting belt.

[0008] To prevent the adjustment belt from falling off, preferably, the unlocking component includes a control rod fixedly installed on the locking teeth, an unlocking block slidably installed on the fixed block, a locking groove opened on the unlocking block, and the end of the control rod inserted into the locking groove. When the unlocking block moves upward, the control rod pulls the locking teeth upward.

[0009] To lock the fixing block, a locking groove is further provided on the fixing block, and a locking block is fixedly installed on the unlocking block. The locking block is adapted to the locking groove, and when the locking block slides into the locking groove, the unlocking block is locked.

[0010] To facilitate adjustment according to different specifications of water inlet pipes, preferably, the ratio of the length of the adjustment section to the length of the adjustment belt is 1:3.

[0011] To prevent the locking teeth from disengaging, preferably, springs are symmetrically installed inside the fixing block, with the two ends of the springs abutting against the locking teeth and the fixing block, respectively.

[0012] To increase the friction between the adjusting belt and the water inlet pipe, preferably, anti-slip strips are arranged at equal intervals on the inner wall of the adjusting belt, and when the adjusting belt is locked, the anti-slip strips are pressed into the water inlet pipe.

[0013] Compared with the prior art, this utility model provides a crimping device for an automotive engine water inlet pipe joint, which has the following advantages:

[0014] 1. The automotive engine water inlet pipe connector crimping device uses a combination of locking teeth and snap teeth to fasten the adjustment band to the connection between the engine and the water inlet pipe. At the same time, the device is equipped with an unlocking component to allow disassembly while avoiding damage to the adjustment band, enabling the adjustment band to be reused. Furthermore, the locking teeth and snap teeth are used to lock the device by pulling, eliminating the need for tools and effectively improving the installation speed.

[0015] 2. The crimping device for the car engine water inlet pipe joint, after the adjusting belt is tightened, the anti-slip strip presses an indentation into the water inlet pipe. At the same time, the anti-slip strip is embedded in the indentation, which effectively increases the friction between the water inlet pipe and the adjusting belt and avoids the problem of the adjusting belt shifting due to engine vibration.

[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model uses an unlocking component to remove the adjustment belt while preventing damage to the adjustment belt, allowing the adjustment belt to be reused. At the same time, the locking teeth and locking teeth work together to install by pulling the adjustment belt, avoiding the use of tools and improving the installation speed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Reference Figures 1-4 A crimping device for a car engine water inlet pipe connector includes an adjusting belt 1, a fixing block 2 fixedly installed on the adjusting belt 1, a locking area formed between the fixing block 2 and the adjusting belt 1, a locking tooth 3 slidably installed on the fixing block 2, and locking teeth 4 equidistantly installed on the adjusting belt 1 to form an adjusting section. The preferred number of locking teeth 4 in this application is 12. By cooperating with the 12 locking teeth 3, the degree of tightening can be adjusted according to different specifications of water inlet pipes, which is convenient to use. The locking teeth 3 and locking teeth 4 can mesh. The fixing block 2 is provided with an unlocking component. When the locking teeth 3 and locking teeth 4 mesh, the unlocking component locks the adjusting belt 1. After the unlocking component tightens the adjusting belt 1, it can avoid the problem of the locking teeth 3 disengaging after meshing with the locking teeth 4 due to engine vibration, and improve the stability of the adjusting belt 1 after it is locked.

[0026] Specifically, the adjusting band 1 is fastened to the connection between the engine and the water inlet pipe by the cooperation of the locking teeth 3 and 4. At the same time, the unlocking part allows the application to be disassembled without damaging the adjusting band 1, so that the adjusting band 1 can be reused. The locking teeth 3 and 4 are locked by pulling, without the need for tools, which effectively improves the installation speed.

[0027] The unlocking component includes a control rod 6 fixedly mounted on the locking tooth 3. The insertion end of the control rod 6 passes through the fixing block 2, and the fixing block 2 has a corresponding guide channel for the control rod 6. The control rod 6 can slide up and down in the guide channel. An unlocking block 5 is slidably mounted on the fixing block 2. The unlocking block 5 has a slot 10. The end of the control rod 6 is inserted into the slot 10. The insertion end of the control rod 6 is provided with a protrusion that matches the slot 10. After the control rod 6 is inserted into the slot 10, there is a 5mm margin in the horizontal direction between the protrusion and the slot 10 to prevent the control rod 6 from jamming the unlocking block 5 and causing the unlocking block 5 to be unable to move horizontally. When the unlocking block 5 moves upward, the control rod 6 pulls the locking tooth 3 upward, thereby facilitating the disengagement of the locking tooth 3 from the locking tooth 4, and thus facilitating the removal of the adjusting belt 1. This avoids the problem of the adjusting belt 1 being damaged and unable to be reused when it is removed.

[0028] The fixed block 2 has a locking groove 8, and the unlocking block 5 has a locking block 9 fixedly installed on it. The locking block 9 is compatible with the locking groove 8. The length of the locking groove 8 is 5mm, so that the sliding distance of the locking block 9 is consistent with the allowance between the protrusion and the slot 10, avoiding the problem that the unlocking block 5 cannot slide horizontally. When the locking block 9 slides into the locking groove 8, the unlocking block 5 is locked, effectively preventing the unlocking block 5 from moving up and down due to engine vibration, and preventing the problem of the locking teeth 3 and locking teeth 4 from disengaging, thus improving the stability of the adjusting belt 1 during use.

[0029] The length of the adjusting section is 1:3 compared to the length of the adjusting belt 1. Since the length of the adjusting section is less than that of the adjusting belt 1, the adjusting section can be effectively adjusted according to the specifications of the water inlet pipe, while avoiding the problem of the adjusting belt 1 being inconvenient to use due to the excessive length of the adjusting section.

[0030] Springs 7 are symmetrically installed inside the fixed block 2, and the two ends of the springs 7 abut against the locking teeth 3 and the fixed block 2 respectively. With the springs 7, on the one hand, when the adjusting section is inserted below the fixed block 2 and pulled, the locking teeth 3 are pushed upward by the locking teeth 4 and can automatically engage with the locking teeth 4 according to the elastic force of the springs 7. On the other hand, the elastic force of the springs 7 can prevent the locking teeth 3 and locking teeth 4 from disengaging due to vibration when the engine is running.

[0031] Anti-slip strips 11 are evenly arranged on the inner wall of the adjusting belt 1. When the adjusting belt 1 is locked, the anti-slip strips 11 are pressed into the water inlet pipe. After the adjusting belt 1 is tightened, the anti-slip strips 11 press the water inlet pipe with an indentation. At the same time, the anti-slip strips 11 are embedded in the indentation, which effectively increases the friction between the water inlet pipe and the adjusting belt 1 and avoids the problem of the adjusting belt 1 being displaced due to engine vibration.

[0032] In this utility model, after connecting the water inlet pipe to the engine water inlet connector, the adjusting band 1 is placed on the outside of the water inlet pipe. The adjusting section is pulled to pass through the locking area. Then, the adjusting section is pulled according to the specifications of the water inlet pipe through the engagement of the locking teeth 3 and the locking teeth 4, so that the adjusting band 1 is fastened to the outside of the water inlet pipe. At this time, the anti-slip strip 11 presses an indentation on the outside of the water inlet pipe. Then, the anti-slip strip 11 is embedded in the indentation to increase the friction between the adjusting band 1 and the water inlet pipe. After locking, the unlocking block 5 is pushed to move the unlocking block 5 horizontally and insert the locking block 9 into the locking groove 8 to complete the locking of the adjusting band 1. It is convenient to use and can quickly lock the adjusting band 1 at the connection between the engine connector and the water inlet pipe.

[0033] If removal is required, first push the unlocking block 5 to disengage the locking block 9 from the locking groove 8. Then push the unlocking block 5 upward to move the control lever 6 along with the unlocking block 5. Then, pull the locking tooth 3 upward through the control lever 6. After the locking tooth 3 disengages from the locking tooth 4, pull the adjusting belt 1 to remove the adjusting belt 1 from the water inlet pipe, so that the adjusting block can be quickly removed and is convenient to use.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
