Abstract
The utility model relates to a clamping and locking mechanism for a middle axle of a bicycle. A ring sleeve 10 with a concave hole 12 is arranged on a middle axle of a bicycle. The hollow part of a height regulating pipe in an upright post of the bicycle is provided with an elastic pin mechanism which is downward extended and is inserted into the concave hole through the hollow part of the upright post. An elastic pin toggle mechanism is arranged on the height regulating pipe 2. The utility model can realize locking the middle axle through an elastic pin which is used for a post. The structure is simple, and the invisibility is strong. The utility model can be solely used as a bicycle lock of the middle axle, and can also be matched with other mechanisms to finish the bicycle locking function.
Description
The utility model belongs to anti-theft lock for bicycle and makes the field.
Present various locks are owing to have movable inserted link and outside other weak part is exposed to, easily destroyed with simple tools by the robber, and antitheft reliability is relatively poor.For this reason, I have designed " bicycle theft-prevention saddle lock " (application number is 96224176.8), make a saddle can have normal use attitude (keeping flat) and two kinds of lock-in states of antitheft attitude (standing up), and its surface structure as depicted in figs. 1 and 2.In Fig. 1,1 is stay, and 2 for being stuck in the height regulating in the column.The rotating block 3 and 4 that is fixed with a saddle is connected by gusset 5, and seat saddle 6 is fixed on the gusset.7 are lock core hole: seat saddle swivel block can drive a saddle and rotate.This scheme prevents stolen (because when not driving the saddle lock, the seat saddle is in and stands up attitude, and the robber can't ride) of car to a certain extent.
For saddle lock theftproof performance is further strengthened, the purpose of this utility model is a kind of bicycle middle shaft locking mechanism of design, both can make and " bicycle theft-prevention saddle lock " matching used form, also can make the form with independent lock core.Utilize vehicle frame column hollow structure, car axis (being foot-operated rotating shaft of triangular frame base angle end installing) is carried out kayser, and make it have survivable, disguised strong advantage.
The purpose of this utility model is to realize by following design.
Bicycle middle shaft is provided with the ring set that has shrinkage pool; The hollow space of the height regulating in stay is provided with a spring column pin mechanism of extending and inserting described shrinkage pool by the column hollow space downwards; Height regulating is provided with the spring column pin toggle mechanism.
Like this, during spring column pin toggle mechanism in depression bar heads into height regulating, pin is produced to bottom offset, insert in the ring set shrinkage pool that is contained on the axis, axis can't be rotated, shaft locking in the formation.During with the supporting use of bicycle theft-prevention saddle, can further strengthen the theftproof performance of saddle lock; When using as middle shaft lock separately, also has good locking performance.And has survivable, a disguised strong advantage.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
In Fig. 3,1 is stay, 2 for being stuck in the seat saddle height regulating in the stay, 8 is latch, 9 is axis, 10 for ring set with shrinkage pool 12 (can see the ring set 10 that is provided with shrinkage pool 12 on the bicycle middle shaft 9 in Fig. 7, shrinkage pool 12 is uniform on the ring set surface, can have a plurality of), 11 for placing the depression bar on the overturning seat saddle.(can see the situation that is provided with of depression bar 11 in Fig. 4,13 is strut kong).The middle part that is located at the height regulating 2 in the bicycle column is provided with one and extends downwards and can be seen clearly by Fig. 5 and Fig. 6 by the spring column pin mechanism that the column hollow bulb inserts ring set shrinkage pool 12, can see in Fig. 5 when the situation of seat saddle turnover when standing up attitude (being state shown in Figure 2): the depression bar 11 that is arranged on the gusset 5 is filled in the strut kong 13, compressing inclined-plane pin 14 is to bottom offset, thereby make king-rod 15 also thereupon to bottom offset, the king-rod cover 16 also displacements thereupon that are enclosed within on the king-rod 15 and connect firmly with it, and latch 8 is inserted in the shrinkage pool 12 of axis ring sets 10, axis can't be moved and form lock car state; When opening saddle lock and a saddle be in keep flat attitude (state shown in Figure 1) normally, depression bar 11 is upwards dug with gusset 5 and is deviate from strut kong, under action of the spring, reset behind inclined-plane pin 14 releases of pressure, thereby make latch deviate from the shrinkage pool 12 of axis ring set 10, axis 9 is no longer blocked, the people is rideable, and its configuration state as shown in Figure 6.
For the setting that makes this spring column pin system does not influence an adjusting of saddle height, king-rod cover 16 is built-in with the inserted link length adjustment mechanism that negative thread 17 constitutes, and king-rod 15 can be by screwing in or screw out the purpose that screw thread 17 reaches the whole pin of adjusting mechanism length.
Consider when the locking axis, suitable shrinkage pool is not necessarily just arranged over against latch 8 slots, so designed with short cover 18, the automatic contraposition of the shrinkage pool mechanism that spring 19 constitutes is when carrying out locking, if shrinkage pool 12 is not over against the position of latch 8, spring 19 is compressed, only need rotating middle shaft slightly this moment, and when shrinkage pool 12 went to over against latch 8, latch was pressed into automatically under the pressure of spring 19 and forms locking in the shrinkage pool.
Certainly, device of the present utility model also can cooperate with " anti-theft lock for bicycle " and be provided with separately, at this moment, only a lock core 20 need be set in the position that strut kong 13 is set, replace the pin toggle mechanism with the lock core that has cam or similar means, when lock core rotated, cam 21 pushed pin rod 22 (replacing inclined-plane pin 14), can finish lock operation.Its working process such as Fig. 8, shown in Figure 9, Fig. 8 are the normal attitude of using, and Fig. 9 is the locking attitude.
