Abstract
The utility model relates to an anti-theft axle-centre lock, comprising a lock head, a lock core, a lock bolt and a chucking block. The utility model is characterized in that the lock bolt is arranged in a wheel shaft, which is composed of a slide block, a connecting rod and a locking slide block. When the lock is locked, the lock core drives a columella to clamp the lock bolt so as to press a spring, and the locking slide block clamps the chucking block, so a bowl and a shaft sleeve are locked to lock the wheels. When the lock is unlocked, the columella switches above the slide block, the spring returns, the lock bolt returns, the locking slide block and the chucking block are staggered, so the wheels can run. The utility model has the advantages of simple structure, unease sawing, anti-prying, convenient operation, low cost and favorable anti-theft performance. The utility model can be used for the front and the back wheel shafts of cycles and motorcycles.
Description
The utility model belongs to a kind of antitheft axle center lock.
At present, bicycle, lock for motorcycle have of all kinds, as patent 89206092.1 handlebars lock, and 92226568.2 built-in anti-theft lock for bicycle, complex structure, anti-saw tamper-resistant function is not stronger, and it is convenient inadequately to use, and cost is higher.
The purpose of this utility model is to provide a kind of antitheft axle center lock, adorns dead bolt on original axle center, and axle sleeve is pinned, and is difficult for sawed-off prying open, and simple in structure, cost is low.
The utility model is formed dead bolt by tapered end lock core dead bolt, clamping block and is made up of slide block (8), connecting rod (7), locking slide block (6), dead bolt is contained in the groove and endoporus of axle (5), groove floor (12) and axis parallel, slide block (8) also has groove, lock core (2) is arranged in the tapered end (1), on lock core (2) eccentric position pillar (3) is housed.Spring (11) is housed in the tapered end (1), links to each other with slide block (8).Tapered end (1) and axle (5) are with being threaded, and clamping block (10) is fixed on the ripple bowl (9), and clamping block (10) has an inclined flange, is embedded in axle sleeve (4) endoporus one inclined groove.Clamping block (10) also can directly be fixed in axle sleeve (4) endoporus.The groove floor (12) of axle (5) also can be the inclined-plane, and the following and groove floor (12) of locking slide block (6) is parallel, and the inner hole section of locking slide block (6) is a rectangle, and locking slide block (6) is connected with spring (13) with axle (5).
Dead bolt of the present utility model is contained on the axle center, only has tapered end to expose, and adorns clamping block on bicycle or motorcycle ripple bowl or axle sleeve endoporus, and is simple in structure, is difficult for the saw sled, and theftproof performance is good, and is easy to use, and cost is low.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model A-A is to partial sectional view;
Fig. 3 is that the utility model B-B is to sectional view;
Partial sectional view when Fig. 4 is the inclined-plane for the groove floor of the utility model axle;
Fig. 5 is the vertical view of Fig. 4;
Fig. 6 is that the C-C of Fig. 4 is to sectional view.
Tapered end in the utility model (1) can cylinder iron be made, and lock core (2), pillar (3), dead bolt can become with steel or copper, and axle is that steel are made through heat treatment, is difficult for sawed-off.By Fig. 1, Fig. 2, Fig. 3 each part is connected.As shown in Figure 1, in the time of locking, key gently, lock core (2) drives pillar (3), and pillar (3) imbeds in slide block (8) groove, and card is pressed dead bolt, spring (11) compression, locking slide block (6) moves, and blocks clamping block (10).Because the inclined flange of clamping block (10) is embedded in the inclined groove of axle sleeve (4) endoporus, and is fixed on the ripple bowl (9), so ripple bowl (9) and axle sleeve (4) pinning.The only rotatable circle of wheel can't the go-cart walking, and lock is prized not opened, and is difficult for sawed-offly, and theftproof is good.When unblanking, backward rotation key, lock core (2) drive pillar (3) and forward slide block (8) top to, and spring (11) pushes back original position with dead bolt, and locking slide block (6) staggers with clamping block (10).When present embodiment was used for bicycle, the connecting rod diameter was about 2MM, and lock core diameter is about 15MM, and clamping block is about 10MM, wide about 3MM, and the hole of the wave crest position of axle (5) stressed maximum is very little, does not influence the original bearing function of axle.Motorcycle anti-theft axle center lock is identical with the structure of bicycle, can arrange the position of clamping block (10) according to the situation of wheel endoporus.Another kind of situation is, axle (5) has the groove floor (12) of locking slide block (6) to be the inclined-plane, and the following and groove floor (12) of locking slide block (6) is parallel, in locking slide block (6) the rectangle endoporus connecting rod (7) is arranged, spring (13) makes the locking slide block be close to bottom surface (12), and during locking, locking slide block (6) protrudes outside the axle, block clamping block (10), when unblanking, the locking slide block is return in axle (5) groove, no longer protrudes outside the axle, axle sleeve can rotate relative to axle, and wheel can be walked.
