Abstract
The utility model relates to a fire-new bicycle anti-theft mechanism, which is used for the field of the theft protection of a bicycle. The utility model can lock a bicycle hub and a wheel through special spline slide blocks structure; a structure of a bicycle lock is designed to main driving components of the bicycle; the interior of the bicycle hub is provided with two sets of spline slide block devices, and the spline slide blocks arranged at the middle of the spline slide block devices are connected with a stainless steel pull rod arranged in a hollow shaft. The stainless steel pull rod is pushed to make axial motion by a lock core of a dish lock so as to control the axial position of the spline slide blocks which are arranged at the center of the hub, and thus, the bicycle hub and the wheel can be locked. The utility model can be used for the field of the theft prevention of products of motorcycles, boosted vehicles, etc. With using the design, even if vehicles are thieved, the utility model just can be used once more through welding, cutting and substituting components in large amounts. When the risk of theft and the cost of reconstruction approach to or even exceed the price of new bicycles of bulk production, the theft action can be powerfully throttled from criminal motivation.
Description
Technical field
This patent product belongs to the burglar-proof mechanism field, is specifically related to a kind of burglar-proof mechanism that is used for bicycle.
Background technology
At present, the bicycle theft-prevention on the market adopts the external lock mode of installing mostly.Yet, traditional lock just gradually lose its safety effect because, just car can be pushed away away, obtain a complete car as long as offender's mode is by force damaged external lock.
At the defective of prior art, the utility model has used the mature technology in the ambits such as machinery, manufacturing, develops a kind of brand new bicycle theft-prevention mechanism.It utilizes special spline slider structure that bicycle drive shaft and wheel are locked, and in the middle of the main drive disk assembly of car, makes the mechanism design of lock anti-theft capability promote greatly.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of design bicycle rear drum in the middle of the main drive disk assembly of car, that anti-theft capability is high built-in lock.
The technical solution of the utility model is achieved in that the built-in lock of bicycle rear drum comprises flower-drum shell 11, two ends end cap bezel ring, 1 and 9, and the column foot 2 of close end cap bezel ring, 1, it is characterized in that, corrosion-resistant steel pull bar 7 and the phase-locked company of outside dish in the flower-drum, hollow shaft 8 is set on the stainless steel 7, end cap 9, trip ring 6, spline 4, column foot 2, end cap 1 is set on the hollow shaft 8 successively, the part that is positioned at trip ring 6 and spline 4 at hollow shaft 8, with 8 one-tenth whole spline slider 5a that a projection is set of hollow shaft, spline slider 5a upper edge hollow shaft 8 axially has a groove 5b, spline slider 5 cooperates with spline slider 5a key, spline slider 5 is provided with the locating dowel pin 10 that spline slider 5 and corrosion-resistant steel pull bar 7 are positioned, spline 4 and flower-drum shell 11 interference fit.
Similar common in the market being used to of lockout mechanism that connects the corrosion-resistant steel pull bar locks the dish latch mechanism of motor bike, mini-motorcycle brake disc, and its production technology and structure design are all comparatively ripe.Pull bar and such lock binding energy lock transmission device inside from the car body outside.
Beneficial effect
The utility model is design-calculated spline slider device in bicycle drive shaft, and middle spline slider links to each other with the corrosion-resistant steel pull bar in the hollow shaft.Promote the corrosion-resistant steel pull bar by the dish lock pin and make axial motion,, thereby bicycle drive shaft and wheel are locked with the axial location of control flower-drum central authorities spline slider.
Bicycle can reach following target after the built-in lock of rear drum is installed:
1. after from the outside lock core being pushed, pull bar bonded assembly spline slider locks hollow shaft and flower-drum, and wheel can not rotate.
2. after outer lock was opened, pull bar ejected with lock core, and spline slider no longer locks flower-drum and hollow shaft, and wheel can freely rotate.
3. if the dish lock is subjected to exterior violence damage, to at first rupture in the joint of lock core and corrosion-resistant steel pull bar, spline slider can be stayed latched position under the effect of the built-in spring of flower-drum, and wheel equally can be locked, the offender can not be only by the mode of cutting off lock steal bicycle.
4. the change to the flower-drum inner structure can not have any impact to its external structure size and installation dimension, is convenient to batch manufacturing and is widely used in present existing vehicle.
5. the existing bicycle that is using can use the built-in lock of this type flower-drum equally through a little repacking.
Below in conjunction with accompanying drawing and concrete real embodiment the utility model is further elaborated:
Description of drawings
Fig. 1 is the structural representation of the built-in lock of flower-drum, wherein 1: end cap bezel ring,, 2: column foot, 3: lock screw, 4: flower-drum female splines, 5: spline slider, 6: trip ring, 7: corrosion-resistant steel pull bar, 8: hollow shaft, 9: end cap bezel ring,, 10: locating dowel pin, 11: flower-drum shell;
Fig. 2 is the slide block device scheme drawing of the built-in lock of flower-drum, wherein 4: flower-drum female splines, 5: spline slider, 5a: spline slider, 5b: groove, 7: corrosion-resistant steel pull bar, 8: hollow shaft, 10: locating dowel pin;
Fig. 3 is mounted in the built-in lock scheme drawing of flower-drum in the bicycle, wherein 1: end cap bezel ring,, 2: column foot, 3: lock screw, 4: flower-drum female splines, 5: spline sliding fast, 6: trip ring, 7: corrosion-resistant steel pull bar, 8: hollow shaft, 9, end cap bezel ring,, 10: locating dowel pin, 11: flower-drum shell, 12: brake disc, 13: flywheel group.
The specific embodiment
The utility model is by the groove 5b on the locating dowel pin 10 process spline slider 5a, to corrosion-resistant steel pull bar 7 and spline slider 5 location, thereby making corrosion-resistant steel pull bar 7 drive spline slider 5 endwisely slips, be spline fitted between the spline slider 5a on spline slider 5 and the hollow shaft 8, flower-drum female splines 4 is an interference fit with flower-drum shell 11.Therefore, after spline slider 5 embeds in the flower-drum female splines 4, with locked, limit the rotation of flower-drum shell 11 between spline shell 11 and the hollow shaft 8, bicycle is locked; After spline slider 5 skidded off flower-drum female splines 4, the locking between spline shell 11 and the hollow shaft 8 was disengaged, and flower-drum shell 11 just can freely rotate.
Whole lockout mechanism is by corrosion-resistant steel pull bar 7 and the phase-locked company of outside dish, after outside dish lock is destroyed, to at first rupture in the joint of pull bar 7, among spring on the trip ring 6 will push spline slider 5 flower-drum female splines 4 from flower-drum inside, flower-drum shell 11 was locked on the hollow shaft 8 equally.
Open the dish lock in the time of by bike, spline slider 5 ejects with lock core, and wheel can rotate.As long as pressing the lock core of ejection during the lock car just can lock trailing wheel.
