Abstract
The utility model relates to an extendible bolt mechanism, comprising a shell sliding sleeve and a sliding bolt whose lower part is connected with a gear shaft. The upper sleeve of the gear shaft is provided with an active and a passive gears, which are serially connected together, wherein, the active gear is engaged with a gear rack which is arranged at a shell and is in parallel with the sliding sleeve and the upper part of the passive gear is engaged with a gear rack part at the downside of the sliding bolt through an opening at the downside of the sliding sleeve. The shell is also provided with a component which acts on the sliding sleeve and a return spring. When the sliding sleeve is pushed forward, the active and the passive gear bodies drive the sliding bolt to extend out of the sliding sleeve body; when the sliding sleeve is loosened, the sliding sleeve returns under the action of the return spring and simultaneously drives the sliding bolt to retract to the sliding sleeve body through the active and the passive gear bodies.
Description
The utility model relates to a kind of expansion bolt mechanism.
Existing bicycle lock is generally the sealing of O type and the U type seals two kinds.The major defect of O type lock is easily to be pried open, and is unfavorable antitheft.Though the U-shape lock security performance is better,, not only unblanks or go up latching operation to bother, and easily scatter and disappear because U type bolt and lock body are independent each other.In order to overcome above-mentioned shortcoming, need a kind of straight formula that is attached on bicycle or the Motorcycle Front Fork of design to lock (as shown in Figure 2,15 is left lock body among the figure, 16 is right lock body, 17 for passing the locking bolt with Telescopic of front vehicle wheel, and 18 is bicycle front fork, and 19 is wheel installation site line), and less in order to make this be locked in the unlocking condition lower volume, then must design a kind of latch mechanism with Telescopic.
The purpose of this utility model is that a kind of expansion bolt mechanism will be provided, and when the sliding sleeve that acts on this mechanism when external force moved ahead, the sliding bolt in its body just stretched out forward, and when external force was eliminated, cunning bolt and sliding sleeve were just in the indentation housing.
The utility model comprises housing, front and back ends passes the sliding sleeve of housing back and front supporting hole seat and places the interior rear portion downside of sleeve body to have the sliding bolt of section of rack, the sliding sleeve below is connected with gear shaft, be arranged with serial connection all-in-one-piece master, driven gear on the gear shaft, the tooth bar that the driving gear sliding sleeve interior with being located at housing parallels is meshed, and the top of driven gear is meshed with the section of rack of sliding bolt by the opening of sliding sleeve downside.Also be provided with the return spring assembly that acts on sliding sleeve in the housing.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model organigram.
Fig. 2 is the utility model application example figure.
With reference to accompanying drawing, the utility model comprises housing 1, and front and back ends passes the sliding sleeve 4 of housing front and back supported hole seat 2,3 and places the interior rear portion downside of sleeve body to have the sliding bolt 6 of section of rack 5.The sliding sleeve below is connected with gear shaft 7, be arranged with serial connection all-in-one-piece master, driven gear on the gear shaft, driving gear 8 is meshed with the tooth bar of being located in the housing 9 that parallels with sliding sleeve, and the top of driven gear 10 is meshed with the section of rack 5 of cunning bolt by the opening 11 of sliding sleeve downside.Also be provided with the return spring assembly that acts on sliding sleeve in the housing.
Return spring assembly is by the pole 12 of being located at the sliding sleeve side, and the back-moving spring 13 and the slide block 14 that are sheathed on the pole are formed.Slide block 14 is connected in the upside of sliding sleeve and contacts with the rear end of back-moving spring.
When the rear end with the hand channel sliding sleeve promotes sliding sleeve 4 forward, driving gear 8 just rolls along the tooth bar 9 that is meshed with it; In this simultaneously, just stir the section of rack 5 that is meshed with it with the driven gear that the driving tooth crop rotation rotates counterclockwise, make sliding bolt 6 in sleeve body to preceding stretching out.
When unclamping hand, the front portion of sliding sleeve is just under the effect of back-moving spring in the indentation housing, and in this simultaneously, sliding bolt is also under the stirring of the driven gear that clockwise rotates in the indentation sliding sleeve.
The straight formula that is attached on bicycle or the Motorcycle Front Fork that adopts the utility model to make is locked, and as shown in Figure 2, can promote sliding sleeve when desiring to lock and move ahead, and makes the interior sliding bolt of sleeve body pass wheel and inserts left lock body, promptly locks; After passing through key unlocking, sliding sleeve and sliding bolt be the indentation right lock body just.This bicycle, the forward and backward straight formula lock of sticking of motorcycle of being attached to, not only safe and reliable, and also compact conformation, volume is little, and is easy to use, and its market prospects are considerable.
