Description

Technical Field

[0001] This application relates to the technical field of oil pumps, and in particular to a snowmobile oil pump. Background Technology

[0002] A snowmobile is a vehicle used on snow. Snowmobiles are driven by an internal combustion engine, which draws fuel from the tank and delivers it to the engine via a fuel pump.

[0003] One type of oil pump in the related art is installed in a flat, elongated oil tank, and includes a housing and a pump pipe connected to the housing.

[0004] When the fuel tank is not completely emptied, the residual fuel will evaporate and form fuel vapor as it approaches the engine. When the fuel vapor accumulates to a certain amount in the fuel tank, it can easily explode due to static electricity, posing a certain safety hazard. Utility Model Content

[0005] To reduce safety hazards, this application provides a snowmobile oil pump.

[0006] This application provides a snowmobile oil pump, which adopts the following technical solution:

[0007] A snowmobile fuel pump includes a pump body connected to a connector, the connector being electrically connected to an external power cord inserted into a fuel tank. The pump body is provided with a clamping assembly for clamping the power cord at the connector connection point, and the clamping assembly is provided with a grounding assembly for electrically connecting the power cord in the fuel tank to the snowmobile.

[0008] By adopting the above technical solution, the connection points of externally connected wires and connectors are clamped using a wire clamping assembly, improving the connection effect between the wires and connectors; the wires inside the fuel tank are electrically connected to the snowmobile using a grounding assembly; when static electricity is generated in the wires inside the fuel tank, the static electricity can be conducted to the grounding assembly, and then quickly conducted to the snowmobile's snowmobile, and further conducted to the ground, effectively reducing the risk of static electricity igniting fuel gas inside the fuel tank and improving the safety of snowmobile fuel pump use.

[0009] Optionally, a protective sleeve is provided at the connection between the connector and the wire, and the outer circumferential surfaces of both the connector and the wire abut against the inner circumferential surface of the protective sleeve.

[0010] By adopting the above technical solution, after the wire and the connector are connected, the protective sleeve can tightly wrap the connection between the two, effectively preventing external impurities from entering, and facilitating the subsequent fixing of the connection between the two.

[0011] Optionally, the protective sleeve is provided with a sealing cap for sealing the oil tank filler neck on the side away from the oil pump body, and the wire clamping assembly is provided on the sealing cap.

[0012] By adopting the above technical solution, the clamping assembly is placed on the sealing cover. When the clamping assembly needs to be repaired, the clamping assembly connected to the sealing cover can be removed by opening the sealing cover. The operation is simple and the repair efficiency is improved.

[0013] Optionally, the wire clamping assembly includes a clamping tube disposed on the sealing cover and a buckle disposed on the clamping tube. One end face of the clamping tube has a fastening hole for the protective sleeve to pass through. The outer circumferential surface of the clamping tube has a through hole communicating with the fastening hole. The buckle is U-shaped, passes through the through hole and extends into the fastening hole. The outer side of the buckle abuts against the inner wall of the through hole, and the inner side of the buckle abuts against the protective sleeve.

[0014] By adopting the above technical solution, when it is necessary to clamp the protective sleeve, the buckle is inserted into the fastening hole so that the inner wall of the hole and the protective sleeve are both in contact with the buckle; the protective sleeve is clamped by the buckle, thereby clamping the connection between the wire and the connector.

[0015] Optionally, the buckle has an anti-retraction groove on its inner side, which extends through the buckle along the axis of the clamping tube; when the wire clamping assembly is in the clamping state, the protective sleeve abuts against the bottom wall of the anti-retraction groove.

[0016] By adopting the above technical solution, when the buckle clamps the protective sleeve, the protective sleeve abuts against the bottom wall of the anti-retraction groove, restricting the buckle from moving radially along the clamping tube and improving the clamping effect.

[0017] Optionally, the grounding assembly includes an inner conductive element that abuts against the insulation layer of the wire, an outer conductive element that is electrically connected to the sled, and a transition element that electrically connects the inner conductive element and the outer conductive element, the transition element being mounted on a sealing cover.

[0018] By adopting the above technical solution, when static electricity is generated at the joint, it is conducted to the snowmobile through the inner conductive component, the transition component, and the outer conductive component, thereby reducing the risk of static electricity causing fuel combustion inside the fuel tank and improving the safety of snowmobile fuel pump use.

[0019] Optionally, the oil pump body is provided with an oil inlet pipe, and the side of the oil inlet pipe away from the oil pump body extends to the lowest point inside the oil tank.

[0020] By adopting the above technical solution, the fuel inlet pipe is extended to the lowest point inside the fuel tank, which can maximize the extraction of fuel from the fuel tank, effectively avoid fuel residue in the fuel tank, improve fuel utilization, and reduce resource waste.

[0021] Optionally, the oil pump body is equipped with a level gauge for detecting the liquid level in the oil tank.

[0022] By adopting the above technical solution, a level gauge installed on the oil pump body can monitor the fuel level in the fuel tank; when the fuel level in the fuel tank is low, it can promptly detect and remind the driver to avoid the snowmobile stopping due to insufficient fuel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The wire clamping assembly is used to clamp the connection points of externally connected wires and connectors, improving the connection effect between the wires and connectors; the wires in the fuel tank are connected to the snowmobile through the grounding assembly; when static electricity is generated in the wires in the fuel tank, the static electricity can be conducted to the grounding assembly, and then quickly conducted to the snowmobile's snowmobile, and further conducted to the ground, effectively reducing the risk of static electricity igniting fuel gas in the fuel tank and improving the safety of snowmobile fuel pump use;

[0025] 2. The fuel inlet pipe extends to the lowest point inside the fuel tank to facilitate subsequent fuel extraction and to empty the fuel tank as much as possible. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This embodiment discloses a snowmobile oil pump. (Refer to...) Figure 1A snowmobile fuel pump includes a pump body 1 and a connector 6. The pump body 1 is installed inside the fuel tank of the snowmobile. The connector 6 is disposed on the pump body 1 and is electrically connected to electrical components inside the pump body 1.

[0033] Reference Figure 1 and Figure 2 One end of the oil pump body 1 is connected to the oil inlet pipe 4, and the other end is connected to the oil outlet pipe. The oil inlet pipe 4 is made of flexible metal, which has a certain degree of flexibility and corrosion resistance. One side of the oil inlet pipe 4 extends to the lowest point inside the fuel tank to ensure sufficient fuel extraction.

[0034] Reference Figure 1 A sealing cap 5 is fitted onto the oil outlet pipe, and the sealing cap 5 can be detachably connected to the oil filler port of the oil tank. An electric wire is threaded through the sealing cap 5, one end of which is electrically connected to an external circuit, and the other end of which is electrically connected to a connector 6.

[0035] Reference Figure 1 and Figure 3 The connection between connector 6 and the wire is covered with a protective sleeve 24. Both connector 6 and the wire abut against the inner circumferential surface of the protective sleeve 24.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The sealing cover 5 is equipped with a wire clamping assembly 2 and a grounding assembly 3. The wire clamping assembly 2 is used to clamp the protective sleeve 24. The wire clamping assembly 2 includes a clamping tube 22 and a buckle 23. The clamping tube 22 is cylindrical in shape and is made of insulating material. A fastening hole 21 is opened on one end face of the clamping tube 22, through which the protective sleeve 24 passes. Two through holes 25 are opened on the outer circumference of the clamping tube 22, which are connected to the fastening hole 21. The diameter of the fastening hole 21 is slightly larger than the outer diameter of the protective sleeve 24, which facilitates the insertion and fixation of the protective sleeve 24.

[0037] Reference Figure 3 The buckle 23 is U-shaped and made of elastic material. The buckle 23 includes a connecting part and two insert parts. The connecting part is located between the two insert parts.

[0038] Reference Figure 3 Two insertion parts are inserted into the fastening hole 21 through a through hole 25, respectively. The side of each insertion part away from the axis of the fastening hole 21 abuts against the wall of the through hole 25. Anti-retraction grooves 26 are provided on the side of each insertion part closest to each other. Both anti-retraction grooves 26 pass through the buckle 23 along the axis of the clamping tube 22, and the groove walls of both anti-retraction grooves 26 abut against the outer circumferential surface of the protective sleeve 24. A connecting part connects the two insertion parts.

[0039] Reference Figure 1 and Figure 4The grounding assembly 3 is used for the electrical connection between the clamping assembly 2 and the snowmobile. The grounding assembly 3 includes an inner conductive element 33, an outer conductive element 31, and a transition element 32. The transition element 32 is mounted on the sealing cover 5 and is made of conductive material.

[0040] Reference Figure 1 and Figure 4 The inner conductive component 33 is located at one end of the sealing cover 5 near the oil pump body 1. The inner conductive component 33 includes a conductive sheet 332, a clamping ring 333, and a conductive wire 331. The clamping ring 333 is sleeved on the outside of the protective sleeve 24, and the inner wall of the clamping ring 333 abuts against the outer circumferential surface of the protective sleeve 24, while the outer wall of the clamping ring 333 abuts against the wall of the fastening hole 21.

[0041] Reference Figure 4 The clamping tube 22 has a first conductive hole 34 through which the conductive sheet 332 passes. The protective sleeve 24 has a second conductive hole 36 through which the conductive sheet 332 passes. The clamping ring 333 has a third conductive hole 35 through which the conductive sheet 332 passes.

[0042] Reference Figure 1 and Figure 4 The conductive sheet 332 passes through the first conductive hole 34, the second conductive hole 36, and the third conductive hole 35 in sequence, and abuts against the wire insulation layer inside the protective sleeve 24. One side of the conductive wire 331 is electrically connected to the conductive sheet 332, and the other side of the conductive wire 331 is electrically connected to the end of the transition piece 32 facing the oil pump body 1.

[0043] Reference Figure 1 and Figure 4 One side of the external conductive component 31 is electrically connected to the end face of the transition component 32 extending outside the oil tank, and the other side of the external conductive component 31 is electrically connected to the sled.

[0044] Reference Figure 1 and Figure 4 A level gauge 7 is installed on the fuel pump body 1. The level gauge 7 is used to detect the amount of fuel remaining in the fuel tank. The level gauge 7 includes two connecting rods 72 and two contact switches 71. Both connecting rods 72 are mounted on the fuel pump 1. The two contact switches 71 are each mounted on the side of the connecting rod 72 away from the fuel pump body 1. One connecting rod 72, with one contact switch 71, extends upward to the highest point in the fuel tank to detect the highest point of fuel in the tank. The other connecting rod 72, with one contact switch 71, extends downward to the lowest point in the fuel tank to detect the lowest point of fuel in the tank.

[0045] The implementation principle of a snowmobile oil pump according to an embodiment of this application is as follows: when the external wire connected to the oil tank is electrically connected to the connector 6, the protective sleeve 24 is fitted on the connection between the wire and the connector 6, and both the wire and the connector 6 abut against the inner circumferential surface of the protective sleeve 24 to prevent the connection from being directly exposed inside the oil tank. Then, the conductive sheet 332 passes through the first conductive hole 34 and the second conductive hole 36 and abuts against the insulation layer of the wire inside the protective sleeve 24.

[0046] When static electricity is generated at the connection between the wire and the connector 6, the static electricity is conducted through the conductive sheet 332, the conductive wire 331, the transition piece 32 and the external conductive piece 31, and then to the external sled. Since the sled is in contact with the ground, the electric arc conducted to the sled will eventually be conducted to the ground, thereby realizing the connection between the wire in the fuel tank and the external ground.

[0047] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of this application should be included within the protection scope of this application.
