Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a fuel tank cap. Background Art

[0002] Before and after refueling a car, the fuel tank cap needs to be disassembled and tightened. The conventional method of disassembling and tightening the fuel tank cap is manual tightening. On the one hand, since the torque on the fuel tank cap is relatively short, it is more difficult to directly tighten the fuel tank cap by hand. On the other hand, the fuel tank cap is not easy to tighten, which may cause gasoline to evaporate easily from the tank port.

[0003] In order to facilitate the tightening of the fuel tank cap, a device for assisting the tightening of the fuel tank cap has now appeared (for example, publication number CN211889789U). The tightening device includes a tightening block and a telescopic rod. The tightening block can be adjusted to adapt to fuel tank caps of different sizes, so that the fuel tank cap can be clamped by the tightening block, and the telescopic rod is used to increase the torque to facilitate the tightening operation of the fuel tank cap.

[0004] Although the existing device for assisting the tightening of the fuel tank cap can facilitate the clamping of the fuel tank cap and increase the torque to facilitate the tightening of the fuel tank cap, the auxiliary tightening device needs to be carried as a vehicle tool, and the fuel tank cap is not often removed, resulting in the auxiliary tool being infrequently used, seriously occupying the tool box space, and the auxiliary tool needs to be searched for when it is used, which is inconvenient to use; in addition, the auxiliary tool is prone to slipping during use, and in order to ensure that the auxiliary tool does not slip during use, the fuel tank cap needs to be clamped, which can easily damage the fuel tank cap. Utility Model Content

[0005] In order to solve the technical problems in the above-mentioned background technology that the existing fuel tank cap tightening needs to be equipped with an on-board auxiliary tool, which seriously occupies the on-board space, and the auxiliary tool is inconvenient to use and easily causes damage to the fuel tank cap, the utility model provides a fuel tank cap.

[0006] The technical solution of this utility model is as follows:

[0007] The utility model provides a fuel tank cap, comprising: a cover body, a mounting groove is provided on the side wall of the cover body, two first reinforcing plates are fixedly provided in the mounting groove, a power-assisting handle is rotatably provided between the two first reinforcing plates, the power-assisting handle is arranged on the top of the cover body, the power-assisting handle is located just above the lock hole, and when not in use, the power-assisting handle can be buckled above the lock hole to play a dust-proof role; when the fuel tank cap needs to be twisted, the power-assisting handle can be rotated to flip it outward, and the torque is increased by the power-assisting handle to facilitate the twisting or tightening of the fuel tank cap, and during the use of the power-assisting handle, the first reinforcing plate plays a role of reinforcing the power-assisting handle, so that the power-assisting handle and the cover body are connected as a whole, rather than being connected by a single rotating shaft, so that the force applied by the power-assisting handle can be directly transmitted to the cover body through the first reinforcing plate and the mounting groove, thereby optimizing the force on the power-assisting handle and the cover body, extending the service life, and the first reinforcing plate effectively avoids wear between the power-assisting handle and the cover body.

[0008] Preferably, the mounting groove is vertically arranged, and the two first reinforcement plates are vertically fixedly arranged in the mounting groove, so that the power-assisting handle and the cover body are connected as a whole, and the first reinforcement plates effectively avoid wear between the power-assisting handle and the cover body.

[0009] Preferably, the power assist handle is a long rectangular structure, which is convenient for covering the lock hole.

[0010] Preferably, the distance between the two first reinforcing plates is the same as the width of the power-assisting handle, thereby preventing the power-assisting handle from shaking during use.

[0011] Preferably, the top edge of the cover body is provided with a chamfer along its circumferential direction to facilitate the rotation of the power-assisting handle and prevent the power-assisting handle from colliding and wearing with the top edge of the cover body.

[0012] Preferably, at least one twisting vehicle tool is rotatably provided on the top of the cover body, which can reduce the space occupied by the twisting vehicle tool in the vehicle tool box and facilitate use.

[0013] Preferably, the twisting vehicle tools are distributed on both sides of the power-assisting handle, which optimizes the space layout and avoids interfering with the operation of the power-assisting handle.

[0014] Preferably, the flipping direction of the twisting type vehicle-mounted tool is opposite to that of the power-assisting handle, so that the torque of the twisting type vehicle-mounted tool can be increased through the power-assisting handle, thereby reducing the difficulty of using the twisting type vehicle-mounted tool.

[0015] Preferably, a second reinforcement plate is fixedly provided on the top of the cover body, one end of the torsion type vehicle-mounted tool is rotatably arranged between the two second reinforcement plates, and the other end of the torsion type vehicle-mounted tool protrudes outward from the cover body in the unfolded state. The second reinforcement plate can reinforce the torsion type vehicle-mounted tool, optimize the force, and extend the service life of the cover body and the torsion type vehicle-mounted tool.

[0016] Preferably, an end of the power-assisting handle away from the first reinforcing plate is provided with anti-slip grooves to improve its anti-slip ability.

[0017] It can be seen from the above technical solutions that the advantages of the utility model are:

[0018] 1. The power-assisting handle is located directly above the lock hole. When not in use, the power-assisting handle can be buckled above the lock hole to prevent dust. When the fuel tank cap needs to be twisted, the power-assisting handle can be turned outward to increase the torque through the power-assisting handle to facilitate the twisting or tightening of the fuel tank cap. The fuel tank cap can be twisted conveniently without the use of on-board tools. It is easy to use and will not slip. During the use of the power-assisting handle, the first reinforcement plate and the mounting groove are used together to reinforce the power-assisting handle, so that the power-assisting handle and the cover body are connected as a whole, the force on the power-assisting handle and the cover body is optimized, the service life is extended, and the first reinforcement plate effectively avoids the wear between the power-assisting handle and the cover body.

[0019] 2. The distance between the two first reinforcement plates is the same as the width of the power-assisting handle, thus preventing the power-assisting handle from shaking and being damaged during use.

[0020] 3. At least one twisting vehicle tool is provided on the top of the cover body for rotation, which can reduce the space occupied by the twisting vehicle tool in the vehicle tool box and facilitate use. The twisting vehicle tools are distributed on both sides of the power-assisting handle, which optimizes the space layout and avoids interfering with the work of the power-assisting handle. The flipping direction of the twisting vehicle tool is opposite to that of the power-assisting handle, and the torque of the twisting vehicle tool can be increased through the power-assisting handle, thereby reducing the difficulty of using the twisting vehicle tool.

[0027] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] In a typical implementation of the present invention, Figure 1-Figure 3 As shown, a fuel tank cap is proposed, comprising: a cap body 1 and a power-assisting handle 2 rotatably mounted on the top of the cap body 1, as shown in FIG. Figure 1 As shown, a first reinforcing plate 5 is fixedly provided on the side wall of the cover body 1 by welding or integral molding, two first reinforcing plates 5 are provided and are arranged opposite to each other, and one end of the power-assisting handle 2 is rotatably arranged between the two first reinforcing plates 5 .

[0029] Specifically, the top edge of the cover body 1 is chamfered along its circumferential direction to facilitate the rotation of the power-assisting handle 2 and prevent the power-assisting handle 2 from colliding and wearing with the top edge of the cover body 1. The first reinforcement plate 5 is vertically fixed on the side wall of the cover body 1. The two first reinforcement plates 5 are arranged opposite to each other, and the distance between the two first reinforcement plates 5 is the same as the width of the power-assisting handle 2.

[0030] Specifically, the side wall of the cover body 1 is provided with a mounting groove 7, which is arranged vertically. A first reinforcing plate 5 is fixedly provided on the inner walls on both sides of the mounting groove 7. The power-assisting handle 2 is a long rectangular structure, which is arranged on the top of the cover body 1, and the power-assisting handle 2 is located directly above the lock hole 3 at the top of the cover body 1. One end of the power-assisting handle 2 is rotatably arranged between the two first reinforcing plates 5 through a rotating shaft, and the other end of the power-assisting handle 2 is a free end, so that when not in use, the power-assisting handle 2 can be buckled above the lock hole 3 to play a dust-proof role; when the fuel tank cap needs to be twisted, the power-assisting handle 2 can be rotated to flip it outward (such as Figure 2As shown), at this time, the torque can be increased by the power-assisting handle 2 to facilitate the twisting or tightening of the fuel tank cap. During the use of the power-assisting handle 2, the first reinforcing plate 5 serves to reinforce the power-assisting handle 2, so that the power-assisting handle 2 and the cover body 1 are an integral whole, rather than being connected by a single shaft, so that the force applied by the power-assisting handle 2 can be directly transmitted to the cover body 1 through the first reinforcing plate 5 and the mounting groove 7, thereby optimizing the force on the power-assisting handle 2 and the cover body 1 and extending the service life. In addition, the first reinforcing plate 5 effectively avoids wear between the power-assisting handle 2 and the cover body 1.

[0031] The working principle of the power-assisting handle 2 is that, according to the torque formula M=r×F, by increasing the value of r (i.e., the length of the lever arm), when the M cover-opening torque remains unchanged, the F cover-opening force is reduced, thereby achieving the effect of labor saving.

[0032] It is understandable that, in order to improve the anti-slip ability, anti-slip grooves may be provided at the free end of the power-assisting handle 2 to increase the friction between the power-assisting handle 2 and the operator's hand.

[0033] like Figure 1 As shown, a wrench 4 is also rotatably provided on the cover body 1, and the wrench 4 is also rotatably provided on the top of the cover body 1. There is at least one wrench 4, and it is arranged on both sides of the lock hole 3, specifically on both sides of the power-assisting handle 2, which optimizes the spatial layout and will not interfere with the operation of the power-assisting handle 2. A second reinforcement plate 6 is fixedly provided on the top of the cover body 1. There are two second reinforcement plates 6, and the two second reinforcement plates 6 are arranged opposite to each other. A wrench 4 is rotatably provided between the two second reinforcement plates 6. The wrench 4 is reinforced by the second reinforcement plate 6, the force is optimized, and the service life of the cover body 1 and the wrench 4 is extended.

[0034] Specifically, the tail of the wrench 4 is rotatably arranged between two corresponding second reinforcing plates 6 through a rotating shaft, the head of the wrench 4 (i.e., its working head) is a free end, and the tail of the wrench 4 is away from the rotating end of the power-assisting handle 2. In a non-working state, the wrench 4 is laid flat on the top of the cover body 1, and the unfolding direction of the wrench 4 is opposite to the unfolding direction of the power-assisting handle 2 (such as Figure 3 As shown in the figure, when the wrench 4 is unfolded, its head can extend outward from the edge of the cover body 1, so that it can be used to tighten structures such as bolts. The power handle 2 can extend the torque and reduce the force required for the wrench 4 to work, which is convenient for use and no longer needs to occupy the space of the vehicle tool box.

[0035] It is understandable that in other embodiments, other twisting-type on-board tools can also be rotatably arranged at the second reinforcement plate 6, as long as the unfolding direction can be ensured to be opposite to the power-assisting handle 2, and the working head can extend outward from the cover body 1 when unfolded. There are no excessive restrictions on the specific tool types here.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
