Description

Technical Field

[0001] This invention relates to the field of hose clamp technology, and more particularly to an automotive hose clamp structure with anti-loosening function. Background Technology

[0002] Hose clamps are indispensable connecting fasteners in the piping systems of vehicles such as automobiles and tractors. They are also widely used in many fields such as engineering machinery, ships, HVAC, and water supply and drainage. They are primarily used for fastening connections between various hoses and rigid pipes, and between pipe fittings. With their convenient installation, adjustable fastening force, and strong adaptability, they have become a key basic component for sealing connections in pipelines.

[0003] When using existing automotive hose clamps, in order to facilitate the adjustment of the clamp tightness, a control structure for tightening the screw is usually provided. This structure can directly drive the screw to rotate. However, such control structures are often large in size and easy to operate, making it easy to accidentally tighten the clamp due to accidental contact, which can lead to the hose clamp coming loose. Summary of the Invention

[0004] This invention relates to a car hose clamp structure with anti-loosening function. When the operating head is not pressed, it cannot directly and completely transmit the manually applied rotational force to the clamp bolt. This structurally prevents the hose clamp from loosening due to accidental rotation of the operating head, achieving a reliable anti-loosening effect. Furthermore, when the trigger pin moves to the left, it simultaneously pushes the pressure-bearing component and drives the transmission component to work together. This allows the hose clamp to be lubricated simultaneously during the necessary loosening and unloading operations, effectively preventing the hose clamp from getting stuck and eliminating the need for manual pre-allocation of lubrication time, thus greatly improving the ease of operation.

[0005] In a first aspect, this invention provides an automotive hose clamp structure with anti-loosening function, specifically comprising: a clamp body, wherein an adjusting part is inserted into the front end of the clamp body; the adjusting part is fixedly connected to the clamp body by bolts; an mounting part is fixedly installed on the right side of the adjusting part on the right side; a clamping bolt is rotatably mounted on the mounting part; a clamping part is threadedly mounted on the clamping bolt; the right side of the clamping part is in close contact with the left side wall of the adjusting part on the left side; a lubrication hole is provided on the outer wall of the clamping bolt; a disassembly head is inserted into the right end of the clamping bolt; a connecting head is threadedly mounted on the disassembly head; the disassembly head is fixedly connected to the clamping bolt through the connecting head; a spline groove is provided on the disassembly head, and a trigger post is slidably mounted inside the spline groove. A connecting block is provided on the outer circumference of the trigger post; an operating head is fixedly installed at the right end of the trigger post; a limit spring is embedded between the left side of the operating head and the right side of the connecting head; a lubrication cavity is inserted into the left end of the clamping bolt; an output hole is provided on the outer wall of the lubrication cavity, and a cross silicone valve is provided in the output hole; the output hole is connected to the lubrication hole; an input pipe is fixedly installed on the left side of the lubrication cavity, and a cross silicone valve is provided inside the input pipe; an extrusion component is slidably installed inside the lubrication cavity; a force-bearing plate is fixedly installed inside the extrusion component; a transmission component is slidably installed laterally inside the lubrication cavity; a transmission block is fixedly installed on the top of the transmission component; a pressure-bearing component is fixedly installed at the right end of the transmission component.

[0006] The right side of the pressure-bearing component is in contact with the left end of the trigger post; a restoring spring B is embedded between the left side of the pressure-bearing component and the right side of the lubrication cavity.

[0007] The left end of the input pipe protrudes beyond the left end of the clamping bolt; the left end of the input pipe is threadedly connected to an oil replenishment container; the top of the transmission block has an inclined structure; the inclined surface of the transmission block is in close contact with the inclined surface of the force plate.

[0008] The bottom of the force-bearing plate is inclined; a restoring spring A is embedded between the interior of the extrusion member and the interior of the lubrication cavity.

[0009] When the operating head is subjected to pressure, it can move to the left along with the trigger pin.

[0010] When the trigger post moves to the left, the docking block will engage with the spline groove of the disassembly head; when the trigger post moves to the left, it will push against the pressure component.

[0011] When the pressure-bearing component is subjected to a leftward pushing force, it will move the transmission component and the transmission block to the left; when the transmission block moves to the left, it will use its own inclined surface to push against the inclined surface of the force-bearing plate.

[0012] When the inclined surface of the force-bearing plate is pushed, it will carry the extrusion component along the lubrication cavity.

[0013] When the extruder moves along the lubrication cavity, it squeezes the lubricating oil inside the lubrication cavity.

[0014] The lubricating oil inside the lubrication cavity, after being squeezed, flows through the output hole and lubrication hole onto the threaded part of the clamping bolt.

[0015] This invention provides a car hose clamp structure with anti-loosening function, which has the following beneficial effects:

[0016] 1. This hose clamp is designed with a press-triggered force transmission structure. Only when the operating head is pressed to the left to engage the spline groove of the disassembly head can the rotational force be transmitted to the clamp bolt. When not pressed, the operating head cannot transmit force directly. This structure prevents the hose clamp from loosening due to accidental rotation of the operating head, achieving mechanical anti-loosening and ensuring the firmness and sealing of automotive pipeline connections.

[0017] 2. When the operating head of this hose clamp is pressed to trigger the force transmission, the trigger column pushes the pressure-bearing component in conjunction. Through the cooperation of the transmission component, transmission block and the inclined surface of the force plate, the extrusion component squeezes the lubricating oil in the lubrication chamber. The lubricating oil flows precisely to the threaded part of the clamp bolt through the output hole and lubrication hole, so that the necessary operation of loosening and unloading the hose clamp and the lubrication operation are carried out simultaneously. There is no need to manually reserve lubrication time separately, which greatly simplifies the operation steps.

[0018] 3. This hose clamp utilizes a mechanical linkage structure to achieve precise extrusion and delivery of lubricating oil to the threaded parts of the clamp bolt, specifically solving the friction and jamming problem in the core transmission parts of the hose clamp, preventing thread corrosion and tightening jams, extending the service life of the hose clamp, and ensuring smooth disassembly, assembly, and adjustment of the hose clamp.

[0019] 4. This hose clamp integrates the anti-loosening force transmission structure and the automatic lubrication structure. Both functions are triggered simultaneously by a single pressing action. There is no need to add a separate lubrication operation component and drive structure, nor is there a need for manual application and lubrication. This reduces the workload and labor costs of later maintenance of automotive hose clamps, while avoiding problems such as uneven application and omissions in manual lubrication, and ensuring the stability of lubrication effect.

[0020] 5. The clamp body and adjustment part of this hose clamp adopt a detachable design, and the lubrication part, the anti-accidental contact part and the clamping bolt are all independent detachable structures. When the clamp body is damaged, the adjustment part and each auxiliary part can be disassembled and reused, avoiding the scrapping of the entire hose clamp due to the damage of a single part of the clamp body, and greatly improving the utilization rate of the parts.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] refer to Figures 1 to 8This invention proposes a car hose clamp structure with anti-loosening function, comprising: a clamp body 1, an adjusting part 2 inserted at the front end of the clamp body 1; the adjusting part 2 is fixedly connected to the clamp body 1 by bolts; an mounting part 3 is fixedly installed on the right side of the right adjusting part 2; a clamping bolt 4 is rotatably installed on the mounting part 3; a clamping part 5 is threadedly installed on the clamping bolt 4; the right side of the clamping part 5 is in contact with the left side wall of the left adjusting part 2; a lubrication hole 6 is provided on the outer wall of the clamping bolt 4; a disassembly head 7 is inserted at the right end of the clamping bolt 4; a connecting head 8 is threadedly installed on the disassembly head 7; the disassembly head 7 is fixedly connected to the clamping bolt 4 through the connecting head 8; a spline groove is provided on the disassembly head 7, and a trigger post 9 is slidably installed inside the spline groove; a pair of... Connector 10; an operating head 11 is fixedly installed on the right end of trigger post 9; a limit spring 12 is embedded between the left side of operating head 11 and the right side of connector 8; a lubrication chamber 13 is inserted into the left end of clamping bolt 4; an output hole 14 is opened on the outer wall of lubrication chamber 13, and a cross silicone valve is installed in the output hole 14; the output hole 14 is connected to lubrication hole 6; an input pipe 15 is fixedly installed on the left side of lubrication chamber 13, and a cross silicone valve is installed inside the input pipe 15; an extrusion member 17 is slidably installed inside lubrication chamber 13; a force plate 18 is fixedly installed inside extrusion member 17; a transmission member 20 is slidably installed laterally inside lubrication chamber 13; a transmission block 21 is fixedly installed on the top of transmission member 20; a pressure member 22 is fixedly installed on the right end of transmission member 20.

[0036] In Example 2, based on Example 1, the right side of the pressure-bearing component 22 is in contact with the left end of the trigger post 9; a restoring spring B23 is embedded between the left side of the pressure-bearing component 22 and the right side of the lubrication cavity 13; the left end of the input pipe 15 protrudes from the left end of the clamping bolt 4; an oil replenishment container 16 is threaded to the left end of the input pipe 15; the top of the transmission block 21 has an inclined structure; the inclined surface of the transmission block 21 is in contact with the inclined surface of the force plate 18; the bottom of the force plate 18 has an inclined structure; a restoring spring A19 is embedded between the interior of the extrusion component 17 and the interior of the lubrication cavity 13; operation When the head 11 is under pressure, it can move the trigger pin 9 to the left. The clamp 1 is fitted into the appropriate position of the car pipeline, and then the operating head 11 is pressed to the left, so that it moves the trigger pin 9 to the left after being under pressure, so that the mating block 10 on the trigger pin 9 is engaged into the spline groove of the disassembly head 7. At this time, the operating head 11 can pull the disassembly head 7 and the clamping bolt 4 to rotate. Without pressing the operating head 11, the operating head 11 cannot directly and completely transmit the manually applied rotational force to the clamping bolt 4, thus avoiding the phenomenon of the hose clamp becoming loose due to the operating head 11 being rotated by mistake, and effectively preventing loosening.

[0037] In Example 3, based on Example 1, after the trigger post 9 moves to the left, the docking block 10 will engage with the spline groove of the disassembly head 7; when the trigger post 9 moves to the left, it will push the pressure member 22; after the pressure member 22 is pushed to the left, it will move the transmission member 20 and the transmission block 21 to the left; when the transmission block 21 moves to the left, it will use its own inclined surface to push the inclined surface of the force plate 18; after the inclined surface of the force plate 18 is pushed, it will move the extrusion member 17 along the lubrication cavity 13; when the extrusion member 17 moves along the lubrication cavity 13, it will squeeze the lubricating oil inside the lubrication cavity 13; after the lubricating oil inside the lubrication cavity 13 is squeezed, it will flow through the output hole 14 and the lubrication hole 6 to the threaded part of the clamping bolt 4; when the trigger post 9 moves to the left... When in motion, it will also push the pressure-bearing component 22, causing the pressure-bearing component 22 to be pushed to the left, which will move the transmission component 20 and the transmission block 21 to the left. When the transmission block 21 moves to the left, it will use its own inclined surface to push the inclined surface of the force plate 18. After the inclined surface of the force plate 18 is pushed, it will move the extrusion component 17 along the lubrication cavity 13. Then, by the extrusion component 17 moving along the lubrication cavity 13, the lubricating oil inside the lubrication cavity 13 will be squeezed. After the lubricating oil is squeezed, it will flow through the output hole 14 and the lubrication hole 6 to the threaded part of the clamping bolt 4. Thus, the hose clamp can complete the lubrication work simultaneously in the necessary step of loosening and unloading the hose clamp, effectively avoiding the phenomenon of hose clamp jamming, and without the need for manual special time for lubrication.

[0038] The working principle of this embodiment is as follows: When in use, first, the clamp 1 is fitted into the designated position of the automotive pipeline. Then, press the operating head 11 to the left, so that the trigger pin 9 moves to the left under pressure, causing the docking block 10 on the trigger pin 9 to engage in the spline groove of the disassembly head 7. At this time, rotating the operating head 11 will drive the disassembly head 7 and the clamping bolt 4 to rotate synchronously. If the action of pressing the operating head 11 is not performed, the operating head 11 cannot directly and completely transmit the manually applied rotational force to the clamping bolt 4, which can effectively prevent the hose clamp from loosening due to the accidental rotation of the operating head 11, and achieve a reliable anti-loosening effect. At the same time, during the leftward movement of the trigger pin 9, it will push the pressure receiving component 22. The pressure receiving component 22 is driven by the leftward pushing force to drive the transmission component 20 and the transmission block 21 to move to the left synchronously. When the transmission block 21 moves to the left, it pushes against the inclined surface of the force plate 18 through its own inclined surface, so that the force plate 18 drives the extrusion component 17 to move along the lubrication cavity 13, thereby extruding the lubricating oil inside the lubrication cavity 13. After being squeezed, the lubricating oil flows through the output hole 14 and the lubrication hole 6 to the threaded part of the clamping bolt 4, so that the clamping bolt 4 is lubricated simultaneously during the necessary operation of loosening and unloading. This not only effectively prevents the clamp from getting stuck, but also eliminates the need for manual lubrication time, greatly improving the convenience of operation and work efficiency.
