Description

The spike formula device that automatically locks

The utility model relates to a kind of spike formula device that automatically locks, and is that a kind of bicycle, power assist vehicle, motorcycle etc. of being applicable to rely on antitheft, the Anti-prizing lockset of the sulky vehicle that spikes stop.

Usually the anti-theft vehicle lock that more generally uses is pincerlike lock, and the shell of this lockset is iron sheet and makes, as long as pry open lock housing, pushes up fork lightly, just can open lock without key.Same those steel wire locks, chain lock etc. also are unable to undergo pliers, hammer etc. and beat.After above-mentioned these locks were destroyed, vehicle was still intact, and the car stealer still can reach the purpose of stealing car.Steal the generation of car incident in order to stop various two wheelers, various locks are come out one after another.The patent No. is to be provided with warning circuit in lockset for " the vehicle anti-theft warning device " of " 94227903.4 ", and utilize the vehicle body action of gravity to make the switch switching of circuit, car stealer's moving vehicle just can trigger warning circuit, this electronic safety lock has warning function, in case but that warning circuit breaks down is still the same as lockset, anti-sled poor-performing.The patent No. is that " 94226899.7 " " the upright lock of Bicycle support " structure is relatively more novel, complicated, and anti-theft effect is better, but machine components are many, and assembly technology is difficult, so manufacturing cost is higher relatively.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art and defective, for the user provides a kind of antitheft, device that automatically locks that pick-proof is effective.

Task of the present utility model be achieved in that automatically lock this spike formula device comprise tapered end, lock core, dead bolt, housing, main locking bar axially have gear teeth, and, perhaps be connected with connecting rod with semi-circle gear on being fixed on spike by gear train by gear train and the semi-circle gear engagement that is fixed on the spike.Spike supports immediately, semi-circle gear driven gear group, thus main locking bar is stretched in the wheel automatically, wheel can not be rotated; The main locking bar of this device of locking can be " L " type, and its end is fixed a protecting cap, and after locking, this protecting cap covers the trailing wheel shaft nut; The dead bolt of this device of locking is fixedlyed connected with lock core, dead bolt is three forked types, and its three ends insert the gear of locking respectively, in the wheel face circular hole of semi-circle gear and the keyway of tapered end, even with instrument main locking bar is destroyed or sawed-off after, the dead bolt part of this device of locking still can not be opened.

The utility model can automatically lock in the spike support immediately, overcome the trouble of locking again after general lock stops, the protecting cap of main locking bar covers the trailing wheel shaft nut after locking, dead bolt also can make the gear of locking, semi-circle gear and tapered end fix simultaneously, and spike can not be rotated, and it is antitheft, the pick-proof function admirable, this back vent of locking device and vehicle welds together, if destroyed lock, also just destroyed car, robber's car attempt of car stealer is cannot succeed.

Accompanying drawing is a kind of embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

Fig. 4 is the another kind of structural representation of the utility model.

Fig. 5 is the utility model scheme of installation.

Fig. 1, Fig. 2, Fig. 3, Fig. 5 are a kind of embodiment of the present utility model.Label shown in the drawings is: 1-vehicle frame, 2-housing, 3-master's locking bar, 4-locking bar gear, 5-transition gear, 6-tooth sector, 7-lock gear, 8-semi-circle gear, 9-dead bolt, 10-spike, 11-tapered end, 12-lock core, 13-protecting cap, 14-connecting rod.Main locking bar 3 is the L type, its right angle arm passes housing 2, axial location at it has the gear teeth, another right angle arm is exposed to outside the housing, its end is equipped with a protecting cap 13, its position is corresponding with the trailing wheel shaft nut, and this protecting cap 13 covers on the trailing wheel shaft nut after locking, and shaft nut is not exposed.The axial gear teeth of main locking bar 3 are by gear train and semi-circle gear 8 engagements that are installed in spike 10.This gear train is that locking bar gear 4, the tooth sector 6 that meshes each other and the gear 7 of locking are formed, and also can adorn a transition gear 5 between locking bar gear 4 and tooth sector 6.Gear teeth meshing on locking bar gear 4 and the main locking bar, semi-circle gear 8 engagements on lock gear 7 and the spike 10, semi-circle gear 8 rotation driven gear groups, make main locking bar 3 towards the wheel direction into and out of.Dead bolt 9 is fixedlyed connected with lock core 12, locking has circular hole on the wheel face of gear 7 and semi-circle gear 8, has keyway on the tapered end 11, and dead bolt 9 is three forked types, its y-bend of back of locking props up in the circular hole that end injects the gear 7 of locking, semi-circle gear 8 respectively, and another end inserts in the keyway of tapered end 11.

Fig. 4, Fig. 2, Fig. 3, Fig. 5 are another kind of embodiment of the present utility model.The semi-circle gear 8 of present embodiment is connected with the gear 7 usefulness connecting rods 14 of locking.When spike rotated, semi-circle gear 8 drove the gear 7 of locking by connecting rod 14 and rotates.Other structure is identical with embodiment 1, is not repeated.

This spike formula back vent that device is welded on vehicle frame 1 that automatically locks is not held (as shown in Figure 5).

During use, key inserts lock core 12 and turns clockwise and be pulled outwardly behind 45 degree, and dead bolt is outside with lock core 12, breaks away from the gear of locking, semi-circle gear and tapered end respectively thereby make its trident prop up end.Spike 10 upwards rotates, and the semi-circle gear 8 that is fixed on the spike rotates thereupon, thereby drives lock gear, tooth sector, transition gear, locking bar gear according to this, and main locking bar is outwards shifted out, and this device of locking is all opened, and vehicle can travel.Otherwise during vehicle parking, spike is swung down to vertically from horizontal level and props up, semi-circle gear 8 in like manner drives the said gear group with spike and above-mentioned counter-rotation, and main locking bar is moved inwardly, trailing wheel is pinned, and the protecting cap of main locking bar afterbody covers the tire shaft nut.Be rotated counterclockwise 45 degree with key and extract, this moment, the trident of dead bolt propped up in the keyway that end injected the circular hole of the gear of locking, semi-circle gear and tapered end, and vehicle just automatically locks.
