Description

Technical Field

[0001] The invention relates to the technical field of fuel tank covers, in particular to a locked, fully sealed, force-free, theft-proof fuel tank cover. Background Art

[0002] The anti-theft fuel tank cap products currently on the market have the following defects: the existing fuel tank cap outer cover, inner cover and claw lock tongue and other components are fixed together. When locking, the fuel tank cap needs to be twisted to the root of the fuel tank opening so that the lock tongue is placed in the tank opening groove before it can be locked. This locking function connects the inside and outside of the fuel tank, which will cause air circulation between the inside and outside of the fuel tank and cause volatilization, which will cause dangerous fuel leakage when encountering bumps on the road.

[0003] At the same time, the fuel tank cap can only be locked when it is twisted to the root of the tank opening and the lock tongue is placed in the tank opening groove. Because the slope of the fuel tank opening of the same size varies from car to car, the inner slope of the fuel tank opening may be too high, making it difficult to install, or too low, causing loose installation and dangerous oil leakage. Such a locking design has poor practical operability and sealing effects.

[0004] In addition, when the outer cover is twisted with destructive force, since all the integral mechanisms are fixed together, the fuel tank cover may be damaged as a whole, and the fuel in the fuel tank may be stolen. Therefore, the overall design of the existing products is not ideal in terms of sealing, practical operability and anti-theft.

[0005] In summary, the present invention solves the existing problems by designing a locking, fully sealed, force-free, anti-theft fuel tank cap. Summary of the invention

[0033] Example, reference Figure 1 , Figure 3 and Figure 4 The small dustproof cover 101 is installed at the center of the end face of the anti-theft outer cover 102. The small dustproof cover 101 is provided with a dustproof cover rivet reserved hole 103. The anti-theft outer cover 102 is provided with an anti-theft outer cover key insertion hole 104. The anti-theft outer cover key insertion hole 104 and the lock hole of the lock core 202 are on the same straight line. The key 201 is respectively adapted to the anti-theft outer cover key insertion hole 104 and the lock hole of the lock core 202.

[0034] Example, reference Figure 2 , Figure 5 and Figure 6 The lock seat positioning plate 301 is arranged in the inner cavity of the anti-theft outer cover 102, and a lock slot plate 302 is sleeved on the boss at the bottom of the lock seat positioning plate 301. A lock claw plate 303 is arranged on the outer side of the lock slot plate 302 and in the inner cavity at the bottom of the lock seat positioning plate 301. A claw 304 is sleeved on the bottom of the lock claw plate 303, and the lock seat positioning plate 301 is respectively combined with the lock slot plate 302, the lock claw plate 303 and the claw 304 by riveting.

[0035] Example, reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 A lock core 202 is installed below the anti-theft outer cover 102 and in the inner cavity of the lock seat positioning disk 301. A lock seat 203 is installed at the bottom of the lock core 202. A lock tongue 205 is assembled at the bottom of the lock seat 203. Two groups of lock tongue springs 204 are provided. The left and right ends of the lock tongue 205 extend to the left and right sides of the lock seat 203 respectively, and are respectively connected to the lock tongue spring locating pins 206 arranged on the left and right side walls of the lock seat 203 through the lock tongue springs 204. The other end of the lock tongue 205 passes through the lock tongue holes 207 opened on the lock seat positioning disk 301 and the lock slot disk 302 in turn, and extends to the outside of the lock slot disk 302. At least three groups of lock tongue holes 207 are provided, and are respectively and evenly provided on the side walls of the lock seat positioning disk 301 and the lock slot disk 302.

[0036] Example, reference Figure 1 The protection component 1, the locking component 2 and the positioning component 3 are assembled into a whole through a press. The anti-theft outer cover 102, the lock seat positioning plate 301, the lock slot plate 302 and the lock claw plate 303 are all made of steel. After the final assembly of the press, the overall thickness has reached an astonishing 0.4 cm thickness. It can effectively resist crowbars and can provide effective protection against various explosive openings. The claw 304 is made of manganese steel and has a rebound characteristic that will tightly buckle on the fuel filler port.

[0037] Specific implementation cases:

[0038] refer to Figure 1-10 After turning the key 201, the lock cylinder 202 controls the lock tongue 205 to be connected in series with the lock seat positioning disk 301 and then in series with the lock slot disk 302, so that the anti-theft outer cover 102, the lock seat positioning disk 301 and the lock slot disk 302 are connected in series due to the relationship of the lock tongue 205. At this time, the product is installed on the fuel tank port. Compared with the traditional fuel tank cap, which needs to be twisted to the root of the fuel tank port to let the lock tongue extend and get stuck in the tank port slot before the key can be removed to complete the locking, the solution does not need to be twisted to the root;

[0039] The lock tongue 205 is not located outside the fuel tank cap, but is connected in series inside the fuel tank cap to achieve the use effect, so that the fuel tank cap does not need to be twisted to the bottom, and the key can be removed to achieve the purpose of locking by only reaching the adaptive position. Because there are no connecting parts between the inside and the outside, no gap will be generated, so that a full sealing effect can be achieved, which solves the problem of oil leakage from the gap caused by the lock tongue or other parts connecting the inside from the outside;

[0040] After locking, turn the key 201 and remove it, the lock tongue 205 will return to the predetermined position of the lock seat, so that the anti-theft outer cover 102, the lock seat positioning plate 301 and the lock slot plate 302 are disconnected from the series connection and restored to independent operation. At this time, the claw 304 of the fuel tank cover has been twisted to the depth suitable for the fuel tank opening, and the claw made of manganese steel has the rebound characteristic and will be tightly buckled on the fuel filling port;

[0041] After the product is locked, the anti-theft outer cover 102 is in an independent state and cannot be removed even by destructive twisting. The anti-theft outer cover 102, the lock seat positioning plate 301 and the lock slot plate 302 are all made of steel. After the final assembly on the press, the overall thickness has reached an astonishing 0.4 cm. It can effectively resist crowbars and provide effective protection against various types of explosive openings.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
