Abstract
The utility model discloses a burglarproof lock of an oil box, which relates to the technology field of burglarproof equipment, and comprises a cylinder body, a pedestal and a top cap. The pedestal comprises a pipe hoop and a close board part arranged outside one end of the pipe hoop; the pipe hoop comprises two semicircles which are connected with each other through a bolt; the cylinder body is sleeved on a close board of the pedestal; connecting screws which are corresponding mutually are arranged on the inner side of the cylinder body and the pedestal respectively; the top cap is sleeved on the cylinder body; a lock body is arranged on the inner side of the top cap; and a U-shaped lock lever is inserted among the top cap, the cylinder body and the lock body through a lockhole. Compared with the prior art, the burglarproof lock solves the problem that the existing oil box lock has bad burglarproof performance, and is mainly suitable for being installed outside an oil filling pipe of motor vehicle oil boxes such as a truck oil box, etc. so as to serve the burglarproof function.
Description
Technical field
The utility model relates to the anti-theft device technical field, outside especially a kind of tank filler tube that is contained in motor vehicle, is used to prevent that other people from opening the theftproof lock that the oil filling pipe lid is extracted the oil in the fuel tank out from oil filling pipe.
Background technology
The theftproof lock of fuel oil in the existing motor vehicle oil tank, mainly contain two kinds of forms, a kind of is to be provided with common built-in lock in the lid of tank filler, the dead bolt external part of this built-in lock is stuck under the oil pipe inner ring, another kind is to have additional again tapered end on the lid of built-in lock, the anti-theft effect of these two kinds of locks is all relatively poor, is easy to by general tamper tool.Therefore, after the truck driver leaves motor vehicle, the stolen incident of fuel oil in the fuel tank often takes place.For this reason, someone has invented the anti-theft device of some fuel tanks, as the cylindrical shell that has some through holes is installed in the fuel tank oil inlet pipe, and cylindrical shell and fuel tank oil inlet pipe fixedly is to be screwed into fixing by screw from the lateral surface of oil inlet pipe, screw is exposed to the outside, the oil stealer also removes screw easily and carries out stolen like this, does not have real antitheft effect.
Summary of the invention
The utility model provides a kind of anti-theft lock of oil tank, mainly is the problem that solves existing fuel tank oil inlet pipe theftproof lock theftproof performance difference.
In order to address the above problem, the technical scheme that the utility model adopted is: it comprises cylindrical shell, base and top cover, described base is partly to be made of pipe collar and the shrouding that is arranged on the pipe collar one end outside, described pipe collar is to be formed by connecting by screw by two sections semi arches, described barrel jacket is on the shrouding of described base, described cylindrical shell inboard with described base on be respectively equipped with mutual corresponding connection screw, described top cover is enclosed within on the described cylindrical shell, lock body is equipped with in this top cover inboard, and the U-shape lock bar is interspersed between top cover, cylindrical shell and the lock body by lockhole.
Can be interspersed with a plurality of adjusting screw(rod)s that are used to regulate base and fuel tank oil inlet pipe elasticity on the above-mentioned pipe collar wall; Above-mentioned top cover can be arc body, and described cylindrical shell top is and the corresponding arc body of described top cover.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, because the U-shape lock bar runs through top cover, cylindrical shell, lock body, cylindrical shell and top cover, therefore be not easy to be pried open by general tool, theftproof performance is good.
2, cover on the shrouding owing to cylindrical shell, top cover covers on cylindrical shell, thereby the connector between connector, cylindrical shell and the base between the connected mode between pipe collar and the oil inlet pipe, the two sections pipe collars all is hidden in the cylindrical shell, and the oil stealer can not remove these connectors, has reached antitheft purpose.
3, base is partly to be made of pipe collar and the shrouding that is arranged on the pipe collar one end outside, pipe collar is to be formed by connecting by screw by two sections semi arches, do not need to change any outward appearance of existing fuel tank oil inlet pipe when therefore installing, as long as the two halves of pipe collar are enclosed within outside the fuel tank oil inlet pipe, again by tightening the screw of two sections pipe collar both sides, base is contained in outside the fuel tank oil inlet pipe securely, installs very convenient.

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 1.
Fig. 4 is the B-B sectional view of Fig. 1.
Summary of the invention
Below in conjunction with the accompanying drawing example, the utility model is described in further detail:
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, it comprises cylindrical shell 1 the utility model, base 2 and top cover 3, base 2 is to be made of pipe collar 2-1 and the shrouding part 2-2 that is arranged on this pipe collar one end outside, pipe collar 2-1 is formed by connecting by screw 10 by two sections semi arches, cylindrical shell 1 is enclosed within on the shrouding 2-2 of base 2, cylindrical shell 1 inboard with base 2 on be respectively equipped with mutual corresponding connection screw 4, top cover 3 is enclosed within on the cylindrical shell 1, lock body 5 is equipped with in this top cover inboard, U-shape lock bar 6 is by lockhole 5-1,5-2 interts between that be provided with and the corresponding through hole of lockhole of top cover 3 and cylindrical shell 1, be interspersed with a plurality of adjusting screw(rod)s 7 that are used to regulate base 2 and fuel tank oil inlet pipe elasticity on the pipe collar 2-1 wall, top cover 3 is an arc body, cylindrical shell 1 top is and top cover 3 corresponding arc bodies that lockhole just is located on the cross section of arc body.
During installation, only need two semi arches of base 2 are enclosed within outside the fuel tank oil inlet pipe, with screw 10 two semi arches are connected and fixed, if screw 10 is tightened the internal diameter of back pipe collar still greater than the external diameter of fuel tank oil inlet pipe, just intert adjusting screw(rod) 7 on pipe collar 2-1 wall by rotation, adjusting screw(rod) 7 is pasted tightly mutually with the oil inlet pipe outer wall, base 2 promptly is securely fixed on the oil inlet pipe, overlap upper shell 1 then, the otic placode 9 that cylindrical shell 1 inboard is provided with is overlapped with the otic placode 9 that the pipe collar 2-1 upper end of base 2 is provided with, otic placode 9 is provided with and connects screw 4, and screw passes connection screw 4 cylindrical shell 1 and base 2 are fixed together, and overlaps upper top cover 3 then, the U-shape lock bar passes top cover, cylindrical shell and lock body, arrive cylindrical shell again, top cover is locked locking bar 6 by lock body 5 again, and whole like this theftproof lock just firmly must be fixed on the fuel tank oil inlet pipe.And the locking member of whole theftproof lock is all covered by cylindrical shell, is difficult to like this be pried open, and has reached antitheft purpose.
