Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to an automotive hose clamp structure that is easy to disassemble and maintain. Background Technology

[0002] Hose clamps are core fasteners used in automotive piping systems to achieve sealed connections between hoses and rigid pipes. They are widely used in engine intake, cooling, fuel, and exhaust systems. Their locking reliability and ease of installation and removal directly affect the overall vehicle piping sealing, maintenance efficiency, and driving safety.

[0003] Most existing hose clamp structures use a threaded assembly for tightening and locking, which drives the hose clamp to tighten and bind it. However, most of them lack a mechanism that can unlock the hose clamp by driving the threaded assembly to rotate multiple times without having to exert a lot of force. This means that when unlocking the hose clamp, a large torque must be output to rotate the threaded assembly multiple times to loosen and release the binding force exerted by the threaded assembly on the hose clamp. This operation is cumbersome and inefficient, and it is not conducive to loosening the hose clamp to disassemble and maintain the pipe or other components that are bound by the hose clamp. Summary of the Invention

[0004] In view of this, the present invention provides an automotive hose clamp structure that is easy to disassemble and maintain, in order to solve the problem that it is not easy to loosen the hose clamp to disassemble and maintain the pipes or other components that are clamped by the hose clamp.

[0005] The technical solution proposed in this invention is as follows: a car hose clamp structure that is easy to disassemble and maintain, specifically including an annular hose clamp, with a rotating post and a positioning shaft respectively rotatably mounted at both ends of the annular hose clamp; a threaded locking shaft is threaded through the rotating post, and a tightening cap is fixedly connected to the first end of the threaded locking shaft; a conical limiting ring is integrally formed on the outer circumference of the threaded locking shaft; a U-shaped slot and a insertion hole are provided on the positioning shaft; an L-shaped transmission plate is slidably mounted on the threaded locking shaft, and a bushing and a sliding groove are provided on the L-shaped transmission plate, wherein the bushing slides with the threaded locking shaft; a centering shaft is fixedly connected to the top of the rotating post, and the sliding groove... The threaded locking shaft is slidably fitted with the centering shaft; the threaded locking shaft is rotatably mounted in the U-shaped groove, and the bushing is inserted into the insertion hole to position the threaded locking shaft in the U-shaped groove; a spring is compressed and fitted on the part of the threaded locking shaft located between the L-shaped transmission plate and the screw cap; a force-applying torsion assembly is rotatably mounted on the centering shaft, and a connecting rod is rotatably connected between the force-applying torsion assembly and the L-shaped transmission plate to drive the L-shaped transmission plate and the bushing to slide toward the screw cap, so as to compress the spring and pull the bushing away from the insertion hole, unlock and release the threaded locking shaft, and when the L-shaped transmission plate slides toward the screw cap, it abuts against the conical limiting ring.

[0006] Furthermore, the force-applying knob assembly is integrally formed from a plum blossom knob and a rotating ring, with a rocker arm fixedly connected to the outer circumference of the rotating ring, and the diameter of the plum blossom knob is 4 to 6 times the diameter of the centering shaft.

[0007] Furthermore, both ends of the connecting rod are rotatably connected to the vertical bend of the swing arm and the L-shaped transmission plate, respectively.

[0008] Furthermore, shaft mounting components are welded to both ends of the annular hose clamp.

[0009] Furthermore, the shaft mounting component is integrally formed from two spaced-apart collars and a U-shaped connecting frame.

[0010] Furthermore, both the rotating column and the positioning shaft are rotatably engaged with the collar.

[0011] Furthermore, the threaded locking shaft is located in the space between the two collars on the shaft post mounting and extends through that space.

[0012] Furthermore, the annular hose clamp is provided with a notch, and the two ends of the annular hose clamp are formed on both sides of the notch.

[0013] The present invention provides an automotive hose clamp structure that is easy to disassemble and maintain, and has the following beneficial effects:

[0014] 1. Through the power amplification and transmission effect of the crank-slider mechanism, when unlocking and loosening the annular hose clamp, the direct forward rotation of the torque assembly can drive the L-shaped transmission plate and bushing to resist the rebound force of the spring that has been compressed once, and continue to compress the spring a second time. This controls the bushing to separate from the U-shaped groove and unlock the threaded locking shaft, and then drives the unlocked threaded locking shaft to disengage from the U-shaped groove. This completes the unlocking and loosening operation of the annular hose clamp in one go. This eliminates the trouble of having to perform the unlocking operation of the threaded locking shaft and the separation and disengagement operation of the threaded locking shaft from the U-shaped groove in steps when loosening the annular hose clamp, which helps to improve the efficiency of unloading and loosening the annular hose clamp and facilitates the disassembly, maintenance or replacement of the hose.

[0015] Second, with the addition of the quick-unlock component, compared with the prior art without the quick-unlock component, the present invention can easily and quickly loosen and unlock the annular hose clamp by simply twisting the force-applying knob component. It eliminates the need for the cumbersome steps of vigorously driving the threaded locking shaft to rotate multiple times to unlock and loosen the threaded locking shaft and the annular hose clamp when loosening the annular hose clamp, making it more practical.

[0016] 3. When the torque amplified by the plum blossom knob is still insufficient to counteract the counterforce of the spring after it has been compressed once, the torque can be further amplified by the drive wrench to ensure that the L-shaped drive plate can be driven to compress the spring a second time, thereby ensuring the normal and effective implementation of the ring hose clamp quick release and unlocking function.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] Example 1

[0038] refer to Figures 1 to 9This embodiment proposes an easy-to-disassemble and maintain automotive hose clamp structure, including an annular hose clamp 1. The annular hose clamp 1 has a notch. A rotating post 102 and a positioning shaft post 103 are rotatably mounted on the two ends of the annular hose clamp 1, respectively. The two ends of the annular hose clamp 1 are formed on both sides of the notch. A threaded locking shaft 104 is threaded through the rotating post 102. A screw cap 1041 is fixedly connected to the first end of the threaded locking shaft 104. A conical limiting ring 1042 is integrally formed on the outer periphery of the threaded locking shaft 104 near the screw cap 1041. A U-shaped slot 1031 and a insertion hole 1032 are provided on the positioning shaft post 103, which are integrally formed. An L-shaped transmission plate 2 is slidably mounted on the smooth part of the threaded locking shaft 104. A bushing 203 is fixedly connected to the vertical section of the L-shaped transmission plate 2. The bushing 203 slides with the smooth part of the threaded locking shaft 104. A threaded locking shaft 104 is threaded through the horizontal section of the L-shaped transmission plate 2. A sliding groove 202 is provided, and a centering shaft 1021 is fixedly connected to the top of the rotating column 102. The sliding groove 202 and the centering shaft 1021 are in sliding engagement. The smooth part of the threaded locking shaft 104 is rotatably locked in the U-shaped groove 1031, and the first end of the bushing 203 is inserted into the insertion hole 1032 to position the threaded locking shaft 104 in the U-shaped groove 1031. The part of the threaded locking shaft 104 located between the L-shaped transmission plate 2 and the screw cap 1041 is pressed. The compression sleeve is equipped with a spring; a force-applying torsion assembly 3 is rotatably mounted on the centering shaft 1021. A connecting rod 201 is rotatably connected between the force-applying torsion assembly 3 and the L-shaped transmission plate 2, which is used to drive the L-shaped transmission plate 2 and the bushing 203 to slide toward the screw cap 1041, so as to compress the spring and pull the bushing 203 away from the insertion hole 1032, unlock and loosen the threaded locking shaft 104. When the L-shaped transmission plate 2 slides in the above direction, it abuts against the conical limiting ring 1042.

[0039] Preferably, the force-applying knob assembly 3 is integrally formed from a plum blossom knob 301 and a rotating ring 302. A rocker arm 3021 is fixedly connected to the outer periphery of the rotating ring 302. The diameter of the plum blossom knob 301 is 4 to 6 times the diameter of the centering shaft 1021.

[0040] Preferably, the two ends of the connecting rod 201 are rotatably connected to the swing rod 3021 and the vertical bend portion of the L-shaped transmission plate 2, respectively.

[0041] Preferably, the annular hose clamp 1 has a shaft mounting component 101 welded to both ends.

[0042] Preferably, the shaft mounting component 101 is integrally formed from two spaced-apart collars 1011 and a U-shaped connecting frame 1012.

[0043] Preferably, both the rotating column 102 and the positioning shaft column 103 are rotatably engaged with the collar 1011.

[0044] Preferably, the threaded locking shaft 104 is located in the space between the two collars 1011 on the shaft mounting member 101 and extends through the space.

[0045] The working principle, specific details, implementation steps, functions and interrelationships of each feature in this embodiment, and the role these features play in realizing this technical solution will be described and explained in detail below:

[0046] In use, the annular hose clamp 1 is first fitted onto one end of the hose to be tightened and positioned. Then, this end of the hose is inserted into the rigid pipe at the node of the vehicle's intake system, cooling system, or oil system. The force-applying torque assembly 3, connecting rod 201, and L-shaped transmission plate 2 are connected to form a deformable crank-slider mechanism. Through this mechanism, the forward and reverse rotation of the force-applying torque assembly 3 can drive the L-shaped transmission plate 2 to slide toward or away from the screw cap 1041. After completing the above operation, the forward rotation of the force-applying torque assembly 3 drives the L-shaped transmission plate 2 and the bushing 203 to slide toward the screw cap 1041, so as to displace the bushing 203 and create a space on the threaded locking shaft 104 for the U-shaped... The slot 1031 is adapted to the snap-fit ​​shaft section. Then, the threaded locking shaft 104 is swung and placed into the U-shaped slot 1031. As the L-shaped transmission plate 2 is driven to slide towards the screw cap 1041, it compresses the spring on the threaded locking shaft 104. After completing the above operations, simply release the force-applying knob assembly 3, releasing the compression and holding force exerted on the spring by the hand through the crank-slider mechanism. The spring will then push back, causing the L-shaped transmission plate 2 and the bushing 203 to slide back away from the screw cap 1041, and control the bushing 203 to engage with the insertion hole 1032, positioning the threaded locking shaft 104 between the rotating column 102 and the positioning column 103 (see reference). Figure 1 and Figure 2 This prepares for the subsequent tightening and locking of the annular hose clamp 1;

[0047] After the threaded locking shaft 104 is temporarily positioned, by rotating the screwdriver clockwise to turn the cap 1041 and the threaded locking shaft 104, the threaded locking shaft 104 is driven to rotate clockwise, which pushes its body towards the rotating column 102. During this process, it compresses the spring on the cap 1041, and transmits its threaded pushing force to the L-shaped transmission plate 2, the bushing 203, and the positioning shaft 103 through the spring. This causes the positioning shaft 103, the rotating column 102, and the two ends of the annular hose clamp 1 to tighten each other, thereby controlling the annular hose clamp 1 to tighten and bind the end of the hose to the rigid pipe (see reference). Figure 3 and Figure 4 );

[0048] In the crank-slider mechanism, the diameter of the plum blossom knob 301 on the force-applying knob assembly 3 is essentially the lever arm that drives the L-shaped transmission plate 2 to slide. This lever arm (diameter) is relatively large, thus amplifying the torque applied by the hand to the force-applying knob assembly 3. When the annular hose clamp 1 is loosened to disassemble, maintain, or replace the hose, the force-applying knob assembly 3 amplifies the torque applied by the hand, causing the L-shaped transmission plate 2 to rotate in the forward direction. The hand can output sufficient torque to drive the L-shaped transmission plate 2 to slide against the counter-thrust of the spring after being compressed once by the screw cap 1041, compressing the spring to its limit until the bushing 203 is pulled away from the U-shaped slot 1031 and the threaded locking shaft 104 is unlocked. When the bushing 203 is pulled away from the U-shaped slot 1031, the vertical plate section of the L-shaped transmission plate 2 abuts against the conical limiting ring 1042 (refer to...). Figure 5 and Figure 6 This will block and limit the L-shaped transmission plate 2, and indirectly position the entire crank-slider mechanism in a stationary state. In this state, the torque applied by the hand to the force-applying torque assembly 3 can be transmitted sequentially through the L-shaped transmission plate 2, connecting rod 201, L-shaped transmission plate 2, and conical limiting ring 1042 to the threaded locking shaft 104, and drive the threaded locking shaft 104 in the unlocked state to disengage from the U-shaped slot 1031 (see reference). Figure 7 Through the power amplification and transmission effect of the crank-slider mechanism, when the annular hose clamp 1 is unlocked and loosened, the direct forward rotation of the torque assembly 3 can drive the L-shaped transmission plate 2 and the bushing 203 to resist the rebound force of the spring that has been compressed once, and continue to compress the spring a second time. This controls the bushing 203 to pull away from the U-shaped groove 1031 to unlock the threaded locking shaft 104, and then drives the threaded locking shaft 104 in the unlocked state to disengage from the U-shaped groove 1031, thus completing the unlocking and loosening operation of the annular hose clamp 1 in one go. This eliminates the trouble of having to perform the unlocking operation of the threaded locking shaft 104 and the separation and disengagement operation of the threaded locking shaft 104 from the U-shaped groove 1031 in steps when loosening the annular hose clamp 1, which helps to improve the efficiency of unloading and loosening the annular hose clamp 1 and facilitates the disassembly, maintenance or replacement of the hose.

[0049] The crank-slider mechanism, together with the spring on the threaded locking shaft 104 and the conical limiting ring 1042, forms a quick-release assembly. If the quick-release assembly is not configured in this invention, when loosening the annular hose clamp 1, it is necessary to vigorously drive the threaded locking shaft 104 to rotate multiple times to push its body and the screw cap 1041 away from the rotating column 102, thereby releasing the compression holding force of the screw cap 1041 on the spring, so as to drive the L-shaped transmission plate 2 to the compressed and extended state of the spring, and control the bushing 203 and the U-shaped slot 1031 to pull away from the threaded locking shaft 104 to unlock it. With the addition of the quick-release assembly, compared with the prior art without the quick-release assembly, this invention can easily and quickly loosen and unlock the annular hose clamp 1 by simply twisting the force-applying twisting assembly 3. It eliminates the need for the cumbersome steps of vigorously driving the threaded locking shaft 104 to rotate multiple times to unlock and loosen the threaded locking shaft 104 and the annular hose clamp 1 when loosening the annular hose clamp 1, making it more practical.

[0050] Example 2, please refer to Figure 10 and Figure 11 :

[0051] This embodiment is based on Embodiment 1, and adds the following content compared to Embodiment 1:

[0052] This embodiment includes a drive wrench 4, which consists of a handle 401 and two mating pins 402 symmetrically welded to the head of the handle 401. Two wrench mating holes 3011 are symmetrically opened on the plum blossom knob 301. When the drive wrench 4 assists in driving the force-applying knob assembly 3, the mating pins 402 are inserted into the wrench mating holes 3011.

[0053] When the torque amplified by the plum blossom knob 301 is still insufficient to counteract the counterforce of the spring after it has been compressed once, the torque can be further amplified by the drive wrench 4 to ensure that the L-shaped drive plate 2 can be driven to compress the spring a second time, thereby ensuring the normal and effective implementation of the quick release and unlocking function of the ring hose clamp 1.
