Description

Technical Field

[0001] The utility model relates to the technical field of fuel tank covers, and more specifically to a flap-type fuel tank cover for automobiles. Background Art

[0002] At present, the basic structure of the commonly used automobile fuel tank cap is a snap-on type. The shortcomings of this snap-on type fuel tank cap in use are: when refueling, the fuel tank cap needs to be removed, and it needs to be installed again after refueling. After repeated removal and installation for a long time, the fuel tank cap and the refueling pipe are worn, and the matching gap between the two is increased, which affects the sealing effect; and when refueling, it is troublesome to remove and install the fuel tank cap, which affects the inconvenience of refueling. Therefore, a flap-type automobile fuel tank cap is proposed to solve the above problems.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field of fuel tank caps without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 and 2 As shown, the utility model provides a flap-type automobile fuel tank cover, including a fuel tank port 1:

[0026] A hinge seat 4 is fixedly provided at the lower end of one side of the oil tank opening 1 , a connecting block 6 is fixedly provided at the movable end of the hinge seat 4 , and an oil tank cover 5 is fixedly provided at one side of the connecting block 6 .

[0027] In order to prevent leakage during driving of the vehicle, an extrusion sealing device 2 is provided at the upper end of the fuel tank cap 5 to close the fuel tank opening 1 to achieve sealing;

[0028] like Figure 3 As shown, the extrusion sealing device 2 includes a connecting groove 21, which is opened on the inner side of the fuel tank cover 5, and a sealing ring 23 is fixedly arranged on the inner side of the connecting groove 21. A rubber block 22 is fixedly arranged on one side of the fuel tank cover 5, and a rubber ring 24 is fixedly arranged on one end of the fuel tank opening 1. The outer surface of the rubber block 22 is matched with the inner wall of the rubber ring 24. Through the mobility of the hinge seat 4, the fuel tank cover 5 can be rotated around the hinge seat 4. When closing the fuel tank opening 1, the fuel tank cover 5 is rotated to the fuel tank opening 1, and the rubber block 22 is inserted into the fuel tank opening 1. Due to the elasticity of the rubber block 22, it can be closely attached to the inner wall of the fuel tank opening 1, thereby achieving a closing effect. Through the closing of the fuel tank cover 5, the sealing ring 23 is squeezed on one side of the rubber ring 24, so as to perform secondary sealing, improve the sealing effect, and avoid the problem of oil leakage during vehicle driving.

[0029] Furthermore, in order to enable the fuel tank cap to be opened quickly and more conveniently when refueling, a tank cap clamping device 3 capable of fixing the fuel tank cap 5 is provided on one side of the fuel tank opening 1, and is used to fix the position of the fuel tank cap 5 when the fuel tank cap 5 is closed;

[0030] like Figure 4 As shown, the tank cover clamping device 3 includes a fixed box 31, which is fixedly arranged on one side of the fuel tank port 1. A rotating rod 33 is penetrated on both sides of the inner wall of the fixed box 31. Tooth grooves are opened at both ends of the rotating rod 33. A rotating block 34 is fixedly arranged at the lower end of the rotating rod 33. A spring card block 32 is fixedly arranged on one side of the fuel tank cover 5. The spring card block 32 penetrates the groove at the lower end of the fixed box 31. The spring card block 32 is movably connected with the rotating block 34. Tooth groove slide bars 35 are respectively penetrated by the two grooves at the lower end of the fixed box 31. The tooth groove slide bar 35 is meshed with the tooth groove on one side of the rotating rod 33. A push block 39 is fixedly provided at the end, and a T-shaped column 36 is fixedly provided at the upper end of the toothed slide bar 35. The upper end of the T-shaped column 36 passes through the groove at the upper end of the fixed box 31. Through the closing of the fuel tank cover 5 and the fuel tank port 1, the spring card block 32 is inserted into the fixed box 31, and is attached by rotating the card block 34. The rotating card block 34 is engaged and transmitted due to the downward force of the toothed slide bar 35. When the fuel tank cover 5 needs to be opened, the push block 39 is pressed to rotate the rotating card block 34 between the toothed slide bar 35, thereby releasing the limit on the spring card block 32, so that the effect of opening the fuel tank cover 5 can be achieved.

[0031] The working principle is as follows: when the utility model is in use, the fuel tank cover 5 is manually rotated to close the fuel tank opening 1, the fuel tank cover 5 is limited and clamped by the tank cover clamping device 3, and the sealing effect is improved by the extrusion sealing device 2, thereby avoiding oil leakage during vehicle driving. When the fuel tank cover 5 needs to be opened for refueling, the pushing block 39 is pressed to release the limiting effect of the rotating clamping block 34 and the spring clamping block 32, thereby pulling the fuel tank cover 5 to achieve the opening effect, which improves the convenience of opening the fuel tank cover 5 as a whole.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
