Abstract
The utility model relates to a novel dustproof structure for a vehicle fuel tank cap lock, which belongs to the field of dustproof devices for the vehicle fuel tank cap locks. The novel dustproof structure consists of a fuel tank cap housing, a dust cap plate, a rubber gasket, a return spring and a rotating shaft, the fuel tank cap housing (1) and the dust cap plate (2) on a lock core component (6) are mutually buckled by adopting a double-ring deep groove, the rubber gasket (3) is arranged at the buckled position, the dust cap plate (2) is connected on the fuel tank cap housing (1) in series by the rotating shaft (5), the return spring (4) is sheathed on the rotating shaft (5), and two ends of the return spring are respectively mounted at the groove bottom of the fuel tank cap housing (1) and the groove bottom of the dust cap plate (2). The novel dustproof structure has good buckling and dustproof effects, and the rubber gasket is deformed due to pressing under the action of force of the return spring, thereby thoroughly preventing dust from entering a lock core from the buckled position and being applicable to dust prevention of the vehicle fuel tank cap locks.
Description
Technical field: the utility model relates to fuel tank for automobile cover lock dust guard, particularly a kind of novel dustproof construction of fuel tank for automobile cover lock.
Background technology: fuel tank for automobile cover lock of the prior art, generally do not consider double-deck preventing dust, dustproof construction is too simple; The general device of not considering self-return causes dust cover normally not snap together sometimes; Not considering generally that rubber is compressed seals, and dustproof effect is undesirable.
Summary of the invention: the purpose of this utility model is to provide a kind of novel dustproof construction of fuel tank for automobile cover lock, utilize the fastening dust-obstructing efficiency of this structure good, dustproof effect is very effective, under the effect of return spring power, rubber sheet gasket is crushed out of shape, so just can stop dust to enter lock core up hill and dale, reach lock core dustproof purpose from fastening.
Formation of the present utility model: form by fuel tank cap housing, dust cover, rubber sheet gasket, return spring and rotating shaft, between the fuel tank cap housing and dust cover on the lock core assembly, adopt the structure of dicyclo deep trouth to fasten mutually, there is rubber sheet gasket at the place at fastening, dust cover is serially connected on the fuel tank cap housing by rotating shaft, suit return spring in rotating shaft, the two ends of return spring are installed in the bottom land of fuel tank cap housing and dust cover respectively.
Compared with the prior art, the utlity model has following advantage:
1. the structure between fuel tank cap housing and dust cover, employing be that the structure of dicyclo deep trouth fastens mutually, the fastening dust-obstructing efficiency of this structure is better.
2. the fastening between fuel tank cap housing and the dust cover is under the effect of return spring power, snaps together all the time, and this dustproof effect is very effective.
3. there is rubber sheet gasket at the fastening place between fuel tank cap housing and dust cover, and under the effect of return spring power, rubber sheet gasket is crushed out of shape, and so just can stop dust from the intrusion of fastening to lock core up hill and dale.
Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the partial enlarged drawing of overlooking of Fig. 1.
1. fuel tank cap housings among the figure, 2. dust cover, 3. rubber sheet gasket, 4. return spring, 5. rotating shaft, 6. lock core assembly.
The specific embodiment: as shown in Figure 1 and Figure 2, form by fuel tank cap housing, dust cover, rubber sheet gasket, return spring and rotating shaft, between the fuel tank cap housing 1 and dust cover 2 on the lock core assembly 6, adopt the structure of dicyclo deep trouth to fasten mutually, at the fastening place rubber sheet gasket 3 is arranged, dust cover 2 is serially connected on the fuel tank cap housing 1 by rotating shaft 5, suit return spring 4 in rotating shaft 5, and the two ends of return spring are installed in the bottom land of fuel tank cap housing 1 and dust cover 2 respectively.
Dicyclo deep trouth on the dust cover 2 by the connection of rotating shaft and under the effect of return spring power, is fastened on the dicyclo deep trouth end face on the fuel tank cap housing 1; Under the effect of spring force, make rubber sheet gasket 3 produce certain deformation, thereby just played the dustproof function.
Claims (1)
1. the novel dustproof construction of a fuel tank for automobile cover lock, form by fuel tank cap housing, dust cover, rubber sheet gasket, return spring and rotating shaft, it is characterized in that: between the fuel tank cap housing (1) and dust cover (2) on the lock core assembly (6), adopt the structure of dicyclo deep trouth to fasten mutually, rubber sheet gasket (3) is arranged at the fastening place, dust cover (2) is serially connected on the fuel tank cap housing (1) by rotating shaft (5), go up suit return spring (4) in rotating shaft (5), the two ends of return spring are installed in the bottom land of fuel tank cap housing (1) and dust cover (2) respectively.
