Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic hose crimping assembly, specifically a hydraulic hose crimping assembly. Background Technology

[0002] In hydraulic systems, hydraulic hose crimping assemblies are key components for achieving pipeline connection and fluid transmission. They mainly consist of connectors, hoses, and threaded blocks. By inserting the connector into the hose rubber and fixing it in place, the pipeline is sealed and connected. However, current hydraulic hose crimp assemblies have significant structural defects in actual use. The way the connector and hose are fixed in the existing crimp assembly makes the connection point the core stress point of the entire assembly. When the hydraulic hose is bent after installation, or sags due to its own weight during long-term use, or is bent by external forces, the tensile and compressive forces on the hose will be highly concentrated at the connection point between the connector and the hose. Because the stress point is always limited to the connector, the stress end of the hose is under excessive stress for a long time, which can easily lead to wear, cracking or even tearing of the hose rubber at the connector insertion point. This damage can not only affect the normal fluid transmission of the hydraulic system and cause leaks, but may also cause safety hazards due to hose damage, reducing the operational reliability and service life of the entire hydraulic system. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulic hose crimping assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic hose crimping assembly, comprising a connector, a hose, and a threaded block. The hose is disposed on the left side of the connector, and the threaded block is disposed on the right side of the connector. A lower groove plate is attached to the bottom of the outer wall of the hose, and an upper groove plate is attached to the top of the outer wall of the hose. Protective pads are fixed to the inner walls of both the lower and upper groove plates. A threaded hole is provided at the connection between the lower and upper groove plates, and a fixing member is inserted into the threaded hole. Support blocks are fixed to the outer walls of both the upper and lower groove plates, and support members are disposed on the side walls of the support blocks.

[0005] Preferably, the lower groove plate and the upper groove plate are semi-circular in shape, and the upper groove plate and the lower groove plate are circular after being fastened together, with the inner diameter matching the diameter of the hose.

[0006] Preferably, the protective pad is made of nitrile rubber.

[0007] Preferably, the left side of the lower groove plate is machined with an inclined groove plate, and the inside is provided with a groove that matches the lower groove plate, which can provide support for the hose when it falls and bends.

[0008] Preferably, the support member includes a support rod, which is fixed to the right side of the support block. A sleeve is fitted onto the end of the support rod away from the support block, and the outer wall of the sleeve is connected to the connector. A stop block is fixed to the outer wall of the support rod, and a nut is threaded onto the right outer wall of the support rod.

[0009] Preferably, the right outer wall of the support rod is threaded, and the thread can be connected to the nut thread.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The left side of the lower groove plate is machined with an inclined groove plate structure of 30°-45°, which can adapt to the angle change when the hose is bent. When the hose is drooping or bent, its bottom end can fit against the left side groove plate of the lower groove plate to provide stable support for the hose. This effectively prevents the hose from tearing and being damaged at the bending position due to bending or drooping, significantly improves the hose's resistance to damage, and extends the service life of the overall device. After the upper and lower groove plates are fastened together, they form a complete circle with an inner diameter that perfectly matches the diameter of the hose, which can firmly wrap the hose. At the same time, the nitrile rubber protective pads on the inner walls of both plates can fit tightly against the outer wall of the hose, which not only enhances the stability of the clamping but also plays a good buffering role, avoiding wear caused by direct contact between the groove plates and the hose, and further protecting the surface of the hose. The support structure, consisting of support blocks, support rods, sleeves, stop blocks, and nuts, enables a stable connection between the lower and upper slot plates and the connector. The stop blocks limit the movement of the sleeves, preventing excessive slippage, while the nuts secure the support rods within the sleeves, ensuring the stability of the support structure. This provides a reliable support foundation for the slot plates to clamp the flexible hose, guaranteeing the stability of the entire support system when the hose is under stress.

[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a hydraulic hose crimping assembly technical solution: A hydraulic hose crimping assembly includes a connector 1, a hose 2, and a threaded block 3. The hose 2 is disposed on the left side of the connector 1, and the threaded block 3 is disposed on the right side of the connector 1. A lower grooved plate 4 is attached to the bottom of the outer wall of the hose 2. The left side of the lower grooved plate 4 is machined with an inclined grooved plate structure with an inclination angle of 30°-45°. This inclined design can adapt to the angle change of the hose 2 when bending, avoiding tearing of the hose surface when the hose 2 is tilted. An upper grooved plate 5 is attached to the top of the outer wall of the hose 2. The upper grooved plate 5 is also made of aluminum alloy and forms a matching structure with the lower grooved plate 4. The upper grooved plate 5 is also semi-circular in shape. After being fastened with the lower grooved plate 4, it forms a complete circle with an inner diameter that perfectly matches the diameter of the hose 2, which can firmly wrap the hose 2 in the middle, providing support and protection. Protective pads 6 are fixed to the inner walls of both the lower groove plate 4 and the upper groove plate 5. The protective pads can fit tightly against the outer wall of the hose 2, providing cushioning and protection. Threaded holes are provided at the connection between the lower groove plate 4 and the upper groove plate 5, and fasteners 7 are inserted into the threaded holes. The fasteners can precisely match the threaded holes of the lower groove plate 4 and the upper groove plate 5 to ensure a firm connection. Support blocks 8 are fixed to the outer walls of both the upper groove plate 5 and the lower groove plate 4. Supporting elements are provided on the side walls of the support blocks 8. The lower groove plate 4 and the upper groove plate 5 are semi-circular in shape, and the upper groove plate 5 and the lower groove plate 4 are circular after being fastened together. The inner diameter matches the diameter of the hose 2. The protective pads 6 are made of nitrile rubber. An inclined groove plate is machined on the left side of the lower groove plate 4, and a groove matching the lower groove plate 4 is provided inside to provide support for the hose 2 when it falls or bends.

[0015] The support includes a support rod 9, which is fixed to the right side of the support block 8. A sleeve 10 is fitted onto the other end of the support rod 9, with threads machined on its outer wall. The thread specifications match those of the nut 12, allowing the support rod 9 and the nut 12 to mate via a threaded connection. The sleeve 10 is fitted onto the end of the support rod 9 furthest from the support block 8, and the outer wall of the sleeve 10 is connected to the connector 1. The connection method is welding or bolting, ensuring that the sleeve 10 and the connector 1 form a single unit. A stop 11 is fixed to the outer wall of the support rod 9, with the outer diameter of the stop 11 being larger than the inner diameter of the sleeve 10. When the sleeve 10 slides on the support rod 9, the stop 11 prevents the sleeve 10 from moving further, thus limiting its movement. A nut 12 is threaded onto the right outer wall of the support rod 9, and the threads can be threadedly connected to the nut 12.

[0016] Working principle: When a hydraulic hose crimping assembly is first used, with the hose 2 in a bent state after installation, the user first attaches the lower groove plate 4 to the outer wall of the hose 4, and then fastens the upper groove plate 5 to the top of the hose 2. After the two groove plates are fastened, the user inserts the fixing piece 7 through the inside of both sides of the lower groove plate 4 and the upper groove plate 5, and then slides the lower groove plate 4 and the upper groove plate 5 to the right. During the sliding, the support rod 9 is inserted into the sleeve 10 through the support block 8. After insertion, when the stop block 11 is in contact with the side wall of the sleeve 10, The user rotates the thread 12 onto the outer wall of the support rod 9 to fix the support rod 9 to the outer wall. Then, the user tightens the fastener 7 at the connection between the lower groove plate 4 and the upper groove plate 5. After tightening, the hose 2 can be clamped by the lower groove plate 4 and the upper groove plate 5. When the hose 2 falls or bends during use, the bottom end of the hose 2 fits against the left side of the lower groove plate 4 to provide stable support for the hose 2. This can effectively prevent the hose 2 from falling or bending, and prevent tearing damage at the bending position.
