Description

Technical Field

[0001] The present invention relates to the technical field of liquid pipe clamps, and particularly to a liquid hose clamp and a motorcycle. Background Art

[0002] Among existing liquid hose clamps, common ones are Robert clamps and medical dampers. ① Robert clamps have a simple shape and are made of plastic. However, the clamping process relies on applying direct external force, which is not labor-saving. After clamping, the self-locking force is insufficient, and it is prone to breakage when the pre-pressure is too large. It is mainly applicable to thin-walled hoses such as those used in winemaking and intravenous drip for animals and plants, with light force application, or only for adjusting the flow rate and not completely blocking. For scenarios such as fuel supply hoses with thick walls and the need for complete blocking, it has problems such as excessive force applied during the locking process and insufficient self-locking force, and is not very suitable. ② Medical dampers, similarly, are applicable to scenarios such as intravenous infusion where less clamping force is required but higher control requirements are needed, and are not applicable to motorcycle fuel hoses.

[0003] Therefore, in view of the immediate on-off requirements of motorcycle fuel hoses in some usage scenarios such as fuel tank disassembly and installation, it is an urgent technical problem to develop a structure that can easily achieve locking and re-opening in motorcycle fuel line hoses. Summary of the Invention

[0004] The purpose of the present invention is to provide a liquid hose clamp. By horizontally pulling the liquid hose clamp as needed, it is possible to achieve complete locking and clamping of the liquid-carrying hose with a small force. After clamping, self-locking can be achieved, completely blocking the fuel passage, and having a good locking effect and being convenient and fast.

[0005] The present invention provides a liquid hose clamp. The liquid hose clamp includes a clamp base and an eccentric wheel installed on the clamp base. The clamp base is square, with holes larger than the diameter of the liquid pipe provided on the front and rear walls. Two rotatable and spaced-apart eccentric wheels are installed on the left and right walls of the clamp base, and the eccentric wheels are located at positions symmetrical with respect to the center line of the hole; when the two eccentric wheels are in the locking position, the distance between the outermost edges of the eccentric wheels is less than the sum of the thicknesses of the two pipe walls of the liquid hose. This structure combines the liquid pipe clamp with the eccentric wheel structure. By pulling the liquid hose, the liquid hose is squeezed until it is closed; at the same time, the distance between the outermost edges of the eccentric wheels being less than the sum of the thicknesses of the two pipe walls of the liquid hose takes into account that the liquid hose is made of an elastic material, and the pipe wall is compressed and deformed during sealing to ensure complete closure of the pipeline; this structure is simple to operate and easy to lock.

[0006] Furthermore: An arc groove that gradually increases is provided on the eccentric wheel from the outermost edge of the eccentric wheel towards the center of the eccentric wheel axis. When the eccentric wheel is in the released position, the liquid hose is located in the arc grooves of the two eccentric wheels. By providing an arc groove on the eccentric wheel, in the released state, the arc groove can accommodate the liquid hose without squeezing the liquid hose, and will not interfere with the normal flow inside the liquid hose.

[0007] Furthermore, the pipe clip seat is divided into a front pipe clip seat and a rear pipe clip seat, and is separated from the axis center line of the installed eccentric wheel. The upper and lower ends of the front pipe clip seat and the rear pipe clip seat are staggeredly matched; at both the upper and lower ends of the front pipe clip seat, extensions are formed extending backward beyond the center line of the eccentric wheel, and the rear pipe clip seat extends backward correspondingly from the center axis of the eccentric wheel to form a retracted portion. This structure makes the pipe clip seat in two parts, which is simple to manufacture and convenient to assemble.

[0008] Furthermore, outer sunk seats are provided on the left and right walls of the front pipe clip seat, and a protruding portion is provided between the eccentric wheel holes. The protruding portion is flush with the inner sunk seat. Inner sunk seats are provided on the left and right walls of the rear pipe clip seat to cooperate with the inner sunk seat; and a protruding boss is provided between the eccentric wheels. The protruding boss is flush with the outer sunk seat, and a limit pin is provided on the wall of the protruding portion, and a pin hole is provided on the protruding boss to cooperate with the limit pin. This structure is simple, easy to fix, and convenient to disassemble.

[0009] Furthermore, limit bosses are provided at both ends of the eccentric wheel. The limit bosses are away from the outermost edge of the eccentric wheel, and the limit bosses cooperate with the lower end faces of the limit surfaces provided on the front and rear walls of the pipe clip seat. This limit boss can effectively prevent the liquid hose from being pulled too much and not reaching the completely closed state.

[0010] Furthermore, the outermost edge end of the eccentric wheel cooperates with the front face of the limit surface. This structure can ensure that the liquid hose is completely in the loosened state after being pulled and released.

[0011] The present invention also provides a motorcycle. A fuel tank is installed on the motorcycle. The fuel tank has multiple low points. Nozzles are provided at the low points at the lower end of the fuel tank. Rubber hoses are connected to the nozzles, and the above-mentioned liquid hose clip is installed on the rubber hoses. For a motorcycle installed with the liquid pipe clip of this structure, when it is necessary to install and disassemble the fuel tank during vehicle maintenance and there is still fuel in the fuel tank, the fuel pipe can be conveniently closed to avoid fuel leakage.

[0012] Beneficial effects: Due to the material and structural characteristics of the present invention, compared with the fuel switch, it can save a large amount of costs, is light in weight, and does not require special fasteners for fixation; it has a labor-saving effect during the locking process, and has great advantages in terms of the final locking force value and the self-locking and anti-loosening force. And the liquid pipe clip and the liquid hose slide smoothly in the reverse locking direction, and the assembly efficiency is higher. Brief description of the drawings

Embodiment

[0014] The present invention provides a liquid hose clip, as Figures 1-7 shown, wherein the liquid hose clip includes a pipe clip seat 1 and an eccentric wheel 11 installed on the pipe clip seat. The pipe clip seat is square, and holes 2 larger than the diameter of the liquid hose are provided on the front and rear walls. Two rotatable and spaced-apart eccentric wheels 11 are installed on the left and right walls of the pipe clip seat. The eccentric wheels are located at positions symmetrical with respect to the center line of the hole 2; the eccentric wheels are installed on the mounting holes 3 on the front and rear walls of the pipe clip seat through eccentric wheel shafts 41. When the eccentric wheel is in the locked position, the distance between the outermost edges 112 of the eccentric wheel is less than the sum of the thicknesses of the two walls of the liquid hose. This structure combines the liquid hose clip with the eccentric wheel structure, and by pulling the liquid hose, the liquid hose is squeezed until it is closed; at the same time, the distance between the outermost edges of the eccentric wheel is less than the sum of the thicknesses of the two walls of the liquid hose, considering that the liquid hose is generally made of an elastic material such as rubber; it has a certain compressibility and to ensure complete closure of the liquid pipe; this structure is simple to operate and easy to lock.

[0015] In this embodiment: a gradually increasing arc groove 113 is provided on the eccentric wheel from the outermost edge of the eccentric wheel towards the center of the eccentric wheel shaft. When the eccentric wheel is in the released position (as Figure 6 shown), the liquid hose is located in the arc grooves of the two eccentric wheels. By providing an arc groove on the eccentric wheel, in the released state, the arc groove can accommodate the liquid hose without squeezing the liquid pipe, and will not interfere with the normal flow of the liquid hose.

[0016] In this embodiment: as Figures 2-3As shown, the pipe clamp seat is divided into a front pipe clamp seat 13 and a rear pipe clamp seat 14, and is separated from the center line of the axis of the eccentric wheel 131, 132, and the upper and lower ends of the front pipe clamp seat 13 and the rear pipe clamp seat 14 are staggered; the holes at the eccentric wheel installation hole are evenly divided into front and rear parts, and the upper and lower ends of the front pipe clamp seat extend backward beyond the center line of the eccentric wheel shaft hole to form an extension part 9, and the rear pipe clamp seat is retracted from the center axis of the eccentric wheel to form a retraction part 10. When the extension part 9 and the retraction part 10 are closed, there is no difference when the front and rear pipe clamp seats are closed. This structure makes the liquid hose clamp seat into two parts, which is simple to make and easy to assemble.

[0017] In this embodiment: an outer sink 31 is provided on the left and right walls of the front pipe clamp seat, and the outer sink here refers to a sink formed away from the center line of the liquid tube hole of the pipe clamp seat, and a protruding part 5 is provided between the eccentric wheel holes, and the protruding part here refers to protruding along the front and rear direction along the separation of the pipe clamp seat, and the protruding part is flush with the outer sink, and an inner sink 8 is provided on the left and right walls of the rear pipe clamp seat to match the outer sink, and the inner sink refers to a sink formed toward the center line of the liquid hose hole; and a protruding boss 45 is provided between the eccentric wheels, and the protruding boss here also refers to a boss protruding along the front and rear direction of the separation of the pipe clamp seat; the protruding boss is flush with the outer sink, and a limit pin 44 is provided on the wall of the protruding part, and a pin hole 4 is provided on the protruding boss 45 to match the limit pin 44. The front pipe clamp seat and the rear pipe clamp seat are locked together by the limit pin and the pin hole. After fixing, the extension part and the retracted part are fitted together; the thickness of the inner and outer sinks after matching is consistent with the thickness of the extension part 9, that is, the thickness of the front and rear walls of the pipe clamp seat; the structure is simple, easy to fix and easy to disassemble.

[0018] In this embodiment: a limiting boss 111 is provided at both ends of the eccentric wheel, the limiting boss 111 is away from the end of the outermost edge 112 of the eccentric wheel, and the limiting boss 111 cooperates with the lower end surface of the limiting surface 6 provided on the front and rear walls of the pipe clamp seat. Here, the limiting boss on the eccentric wheel is provided in the radial direction at both ends of the eccentric wheel 11, and the limiting surface 6 on the pipe clamp seat is provided on the front pipe clamp seat and cooperates with it in the radial direction. The limiting boss can effectively prevent the liquid pipe from being pulled excessively and failing to reach a completely closed state.

[0019] The eccentric wheel structure in the present invention can be an integral structure. Figure 4As shown, it includes an eccentric body 11, and a shaft 41 which is integrally arranged with the body and rotates with the pipe clamp seat. The eccentric in the present invention is made of plastic material, and when the eccentric and the liquid hose are in a relaxed state, the outer surface of the eccentric arc groove is in contact with the outer surface of the liquid hose. Since they are both made of plastic or rubber material, the friction between the two is relatively large, thereby driving the eccentric to rotate to close the liquid hose or loosen the liquid hose accordingly. Of course, the eccentric can also be made of other materials, such as metal, but this structure needs to manufacture protrusions or textures on the outer surface of the eccentric to increase the friction between the eccentric and the liquid hose. The eccentric can also support a split structure, which is the eccentric body and the shaft that can pass through the eccentric body. The pipe clamp seat that makes the eccentric into an integral structure needs to be made into a split structure for easy installation. If the eccentric is made into a split side pipe clamp seat, it can support an integral structure.

[0020] In this embodiment: one end of the outermost edge 112 of the eccentric wheel is matched with the front side of the limiting surface 6. This structure can ensure that the liquid hose is completely in a loosened state after being pulled and released.

[0021] When it is necessary to block the liquid hose, such as Figure 7 As shown, pull the liquid hose and hold the tube clamp seat steady. You can feel the required pulling force gradually increasing with the movement of the eccentric wheel of the liquid hose. Continue pulling until you hear (feel) a "click" sound when the eccentric wheel of the liquid hose is locked in place. The click sound here is caused by the limit boss 11 abutting against the lower end surface of the limit surface 6. At this point, the locking and blocking of the liquid hose is completed.

[0022] When the liquid hose needs to be reopened, such as Figure 6 As shown, pull the liquid hose and hold the tube clamp seat steady. You can clearly feel the pulling force suddenly decrease to almost disappear with a "click" sound. At this time, the click sound comes from the edge of the eccentric wheel that is at the front of the limit surface 6 and causes the liquid hose to be successfully reopened.

[0023] The present invention also provides a motorcycle, wherein a fuel tank is installed on the motorcycle, wherein the fuel tank has multiple low points, and each low point at the lower end of the fuel tank is provided with a fuel nozzle, and each fuel nozzle is connected to a rubber hose, and the above-mentioned liquid hose clamp is installed on the rubber hose. When the motorcycle with the liquid hose clamp of this structure is installed and removed for vehicle maintenance and the fuel tank still has fuel, the fuel pipe can be conveniently sealed to prevent fuel leakage.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
