Description

Technical Field

[0001] This application relates to the field of lawnmower technology, and in particular to an anti-loss fuel tank cover for a ride-on lawnmower. Background Technology

[0002] Ride-on lawnmowers, as efficient large-scale lawn maintenance machinery, are widely used in modern landscaping and home garden maintenance. They are typically equipped with large-capacity fuel tanks to ensure continuous operation for extended periods. Currently, most lawnmower fuel tank caps adopt a threaded or snap-on structure similar to those used in passenger cars, primarily functioning to seal the fuel tank opening and prevent fuel leakage and impurities from entering.

[0003] However, in actual use, due to the need to frequently open the cap to refuel or check the fuel level, users often do not have a free hand to hold the fuel tank cap at all times. Therefore, the fuel tank cap is often left lying aside or on the lawnmower, and it is easy to lose it under some external force. This causes the fuel in the tank to be directly exposed to the air, resulting in evaporation waste and environmental pollution. In addition, external dust and other impurities can enter the fuel tank without hindrance, causing damage to internal parts. Therefore, how to prevent the fuel tank cap from being lost is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides an anti-loss fuel tank cover for a ride-on lawnmower to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is an anti-loss fuel tank cover for a ride-on lawnmower, comprising: a cover body for connecting to the fuel tank opening of the lawnmower's fuel tank, wherein a hanging rope is provided at the bottom of the cover body; and a locking component, including a connecting part and a limiting part, wherein the hanging rope is provided on the connecting part. and The limiting part is connected to the cover by a rope, and is always located inside the lawnmower's oil tank when suspended by the rope and cannot be removed through the oil tank opening of the lawnmower.

[0007] In some embodiments, the limiting part consists of two support arms, which are disposed on both sides of the connecting part, and the circumferential diameter of the two support arms is larger than the diameter of the tank opening.

[0008] In some embodiments, an angle is formed between the two support arms, and the ends of the support arms form abutment portions for engaging with and limiting the fuel tank opening.

[0009] In some embodiments, the cover is provided with an upper connector inside to cooperate with the suspension rope.

[0010] In some embodiments, the connecting part and the upper connecting member are respectively provided with a first connecting groove and a second connecting groove, and a wire groove is provided at the bottom of the first connecting groove and the second connecting groove. The two ends of the suspension rope are provided with limiting balls, and the two limiting balls are respectively located in the first connecting groove and the second connecting groove, and the suspension rope passes through the wire groove.

[0011] In some embodiments, an abutment post is formed within the cover body, and a sponge for breathable filtration is disposed between the abutment post and the upper connector.

[0012] In some embodiments, the upper connector is provided with connecting lugs on both sides, and the upper connector is disposed inside the cover body through the connecting lugs.

[0013] In some embodiments, a sealing rubber component is further provided below the upper connector.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the embodiments of this application, please refer to Figure 1-3 As shown, this application provides an anti-loss fuel tank cover for a ride-on lawnmower, mainly comprising: a cover body 1 for connecting to the fuel tank opening of the lawnmower's fuel tank, wherein a hanging rope 2 is provided at the bottom of the cover body 1; and a locking component 3, including a connecting part 31 and a limiting part 32, wherein the connecting part 31 is provided with the hanging rope 2 and is connected to the cover body 1 through the hanging rope 2, and the limiting part 32 is always located inside the lawnmower's fuel tank and cannot be dislodged through the fuel tank opening of the lawnmower when suspended by the hanging rope 2.

[0023] When the cover 1 is unscrewed, the clip 3 moves with the cover 1 under the pull of the suspension rope 2. However, because the diameter of the limiting part 32 is larger than the oil tank opening, it is always restricted inside the oil tank, so that the cover 1 is connected to the clip 3 through the suspension rope 2, avoiding the loss of the cover 1 after refueling. When the cover 1 is tightened, the suspension rope 2 is naturally stored in the gap between the cover 1 and the oil tank opening, without affecting the seal.

[0024] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0025] Preferably, the limiting part 32 consists of two support arms, which are disposed on both sides of the connecting part 31, and the circumferential diameter of the two support arms is larger than the diameter of the fuel tank opening. Compared with the disc structure, the support arm design reduces the contact area with the fuel in the fuel tank and facilitates insertion from the fuel tank opening; the support arms can be made of elastic plastic material, which can bend and deform, avoiding breakage during assembly or use.

[0026] Specifically, the two support arms form an angle, and the ends of the support arms form an abutment 321. The abutment 321 is used to cooperate with the fuel tank opening for limiting. When the cover 1 is opened and the suspension rope 2 is tightened, the abutment 321 will naturally abut against the inner edge of the fuel tank opening. The 120° angle of support ensures that the locking piece 3 will not tilt, preventing the support arm from accidentally sliding out of the fuel tank opening. Compared with a completely straight locking piece 3, it is less likely to come out of the fuel tank opening.

[0027] Reference Figure 2-3As shown, the cover 1 has an upper connector 11 inside to cooperate with the suspension rope 2.

[0028] Preferably, the connecting part 31 and the upper connecting member 11 are respectively provided with a first connecting groove 311 and a second connecting groove 111. The bottom of the first connecting groove 311 and the second connecting groove 111 is provided with a wire groove 112. The two ends of the suspension rope 2 are provided with limiting balls 21. The two limiting balls 21 are respectively located in the first connecting groove 311 and the second connecting groove 111, and the suspension rope 2 passes through the wire groove 112. The diameter of the limiting ball 21 is smaller than the diameter of the wire groove 112, which ensures that the two ends of the suspension rope 2 are evenly stressed and are not easy to fall off. At the same time, the limiting ball 21 can block the wire groove 112 and prevent a large amount of fuel from entering the cover 1.

[0029] In some embodiments, an abutment post 12 is formed inside the cover 1, and a sponge 13 for air permeability and filtration is provided between the abutment post 12 and the upper connector 11. The sponge 13 can block the second connecting groove 111, and the abutment post 12 and the upper connector 11 cooperate to clamp the sponge 13 block to prevent the sponge 13 from shifting.

[0030] Reference Figure 2-3 As shown, the upper connector 11 is provided with connecting lugs 113 on both sides. The upper connector 11 is disposed inside the cover 1 through the connecting lugs 113. The connecting lugs 113 improve the connection strength between the upper connector 11 and the cover 1, and prevent the upper connector 11 from falling off the cover 1 when the suspension rope 2 is pulled.

[0031] Preferably, a sealing rubber component 14 is also provided below the upper connector 11 to seal the fuel tank cap and the fuel tank opening and prevent fuel leakage.

[0032] Preferably, the suspension rope 2 is made of polyethylene. Polyethylene has excellent chemical corrosion resistance (resistance to gasoline and diesel corrosion) and low density, so it will not increase in weight due to oil immersion in the fuel tank. At the same time, its smooth surface can reduce friction and wear with the edge of the fuel tank opening and extend its service life.

[0033] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
