Abstract
The utility model relates to a fully sealed theft-proof device for a bicycle. The structure of the utility model is that the interior of an iron casing body is provided with a control lock head, a stop bolt, a brake column, a column sleeve pipe, and a stop gear fixed on the left round table of a rear hub. The upper end of the brake column is exposed out of the casing body in the unlocking state, and the stop bolt is inserted into an unlocking hole; the stop bolt exits the unlocking hole in the right direction along with the rotation of a key in the locking state, and simultaneously, the brake column is pressed to make the lower end of the brake column inserted into the concave and hollow position of the stop gear; at this point, the stop bolt can enter a locking hole to make the bicycle wheels not rotate; none component is exposed outside after the locking. The utility model effectively solves the abuse that a lock bar and a lock chain are exposed, and theft-proof purpose is achieved.
Description
The utility model relates to a kind of anti-theft device of bicycle special use.The totally-enclosed alarm of bicycle of lock stile or chain is not revealed in specifically a kind of outside, and it is widely used in the bicycle of various models.
At present, known anti-theft lock for bicycle is mixed bar lock, steel wire lock, chain lock no matter be, all be to be combined by housing, tapered end, chain, lock stile, its common design feature is the lock frame, and chain exposes easily to be pried open or cut off, anti-theft effect is not good, makes the cyclist very troublesome.
The purpose of this utility model provides a kind of overall structure firm in order to overcome weak point of the prior art exactly, and chain or lock stile are not revealed in the outside, and the installation position is appropriate, and is easy to use, is difficult for the totally-enclosed alarm of ruined bicycle.
The purpose of this utility model is achieved in that in the circular irony housing of a band hilt, the control tapered end is housed, stop bolt, the extension spring of stop bolt, column sleeve pipe, brake posts, post extension spring, reinforce formations housing system such as iron and with combined the forming of stopping gear (shown in Figure 1) that is fixed on the bicycle rear axle skin left end round platform.Described control tapered end is fixed on the housing to tie with stop and connects, and the other end of stop bolt is meshed with brake posts in the column sleeve pipe, and an end of column sleeve pipe is fixed on the housing, and the other end is fixed on to be reinforced on the iron, and the two that reinforces iron is separately fixed on the housing; Stopping gear is fixed on the round platform of the bicycle rear axle skin left side; Brake posts is cylindrical, is drilled with two and is respectively open hole and closes closed pore, on one side the column sleeve pipe is opened Yi Changkou, is convenient on one side that the brake posts extension spring moves up and down, corresponding lower end has a hole, be convenient to that the stop bolt inserts and brake posts on open hole be meshed with the pass closed pore.During use, earlier stopping gear is enclosed within on the bicycle rear axle skin left end round platform, be fixed on tightly on the skin with holding screw, again the housing that assembles and bonnet be inserted on the stopping gear on the skin, mix up on the chain stay that the gap is fixed on bicycle tightly and get final product.
The utility model has been compared following remarkable advantage with prior art: the first, and it can not rotate in order to the control rear axle with the lock stile that changes conventional bicycle lock, the drawback that chain exposes, and reaches antitheft purpose.The second, because rational in infrastructure, number of parts and cost almost do not increase.The 3rd, easy to use, be easy to install, debug, be difficult for destroyed.
Below with reference to accompanying drawing the utility model and operating principle are described in further detail.
Fig. 1 is a kind of concrete structure schematic diagram of the utility model.
Fig. 2 is the structural representation of the utility model housing bonnet.
Sequence number among the figure, title:
(1) housing, (2) connecting hole of housing and housing bonnet, (3) the firm iron of control tapered end, (4) stop bolt jump ring, (5) control tapered end, (6) stop bolt extension spring, (7) stop bolt, (8) brake posts, (9) column sleeve pipe, (10) brake posts extension spring clothes-hook, (11) brake posts extension spring, (12) rod is hung in the brake posts extension spring, (13) reinforce iron, (14) stopping gear, (15) rear axle penetrates the hole, (16) the fastening Luo silk of stopping gear, (17) key, (18) backshaft skin penetrates the hole, (19) bonnet.
With reference to Fig. 1,2 firm iron (3), column sleeve pipe (9), brake posts extension spring clothes-hook (10), the reinforcing iron (13) of housing (1) with the control tapered end is fixedly connected; Brake posts (8) can move up and down in column sleeve pipe (9), and column sleeve pipe (9) is connected with stop bolt (7), and the other end of stop bolt (7) is connected with control tapered end (5), and the firm iron (3) of controlling the control tapered end on tapered end (5) and the housing (1) links to each other; Brake posts extension spring (11) links to each other with brake posts extension spring clothes-hook (10), and the other end of brake posts extension spring (11) is hung rod (12) with brake posts and linked to each other; Stop bolt jump ring (4) links to each other with control tapered end (5); One end of column sleeve pipe (9) is connected with housing (1), and the other end of column sleeve pipe (9) is connected with reinforcing iron (13), and the two ends that reinforce iron (13) are separately fixed on the housing (1).Then stopping gear (14) is sleeved on the round platform of bicycle rear axle skin left end, be fixed on tightly on the skin with stopping gear holding screw (16), again the housing that assembles and bonnet are inserted on the stopping gear on the skin, mix up on the chain stay that the gap is fixed on bicycle tightly.To clockwise rotate in the key insertion control tapered end (5) during use, dial stop bolt (7) to right lateral, stop bolt (7) withdraws from the pass closed pore on the brake posts (8), effect by brake posts extension spring (11), brake posts (8) ejects outside shell in column sleeve pipe (9), the use of stop bolt extension spring (6) is arranged simultaneously, and stop bolt (7) forms opening to the open hole of left lateral insertion brake posts (8).When closing, key clockwise rotates, dial the stop bolt and withdraw from open hole on the brake posts (8) to right lateral, toward descending, the calixconcavity place of stopping gear (14) is inserted in the lower end of brake posts (8) to hand, stops that stopping gear (14) turns round with wheel by brake posts (8) top, the effect of stop bolt extension spring (6) is arranged this moment, stop bolt (7) inserts the pass closed pore on the brake posts (8) to left lateral, extracts key.During closed condition, hull outside is not revealed any component, therefore, be difficult for destroyed, thereby play anti-theft effect.
