Description

Self-locking bicycle stand

The utility model relates to a kind of bicycle foot rest that automatically locks, and mainly provides a kind of circular groove and the continuous curve that cylinder the produced motion of permanent seat one side and tensile-elasticity of spring by locking plate, to reach locking and the purpose of opening foot rest.

General prop stand for bicycle framework is made, shape all as shown in Figure 1, mainly constituted by members such as a permanent seat, locking plates, cut the inclined-plane in permanent seat 10 1 sides one square notch 13 is set, what cooperate locking plate 15 tops colludes sheet 16, and in order to play the engagement locking, centre then has one to give prominence to bolt 11, hang spring 12 in order to collude, 14 on lower end bolt is as pole 19 interlocking permanent seats 10 and as rotating shaft device; Locking plate 15 then is a rectangle arc plate shape, and sheet 16 is colluded on the top, and the bottom then has a hook 18 of protruding can catch on spring 12, and is equipped with a bolt 17 in locking plate 15 central authorities, in order to pipe link 19 and locking plate 15, and plays rotating shaft.

The use of Regular Bicycle foot rest sees also shown in Figure 2, then need earlier pole 19 to be pulled by level attitude and go on the upright position, again with locking plate 15 switchings, make the notch that colludes sheet 16 and permanent seat 10 sides 13 engagements of locking plate 15, and produce fastening fastening by spring 12 tensile-elasticities, make the snap action of whole foot rest be difficult for getting loose; When regaining foot rest to level attitude, then above-mentioned action reversed is carried out, foot rest can be returned on the original position, again locking plate 15 is firmly rotated to folding a side, make its locking plate 15 tops collude the notch 13 interior location that sheet 16 is engaged to permanent seat 10; So when stopping the storing foot rest, then need be with the operation mode of two sectional type, can't just foot rest be mounted with action once, there is not operation fast speed convenience yet, especially often because of the elastic force of spring 12 when regaining foot rest, often must firmly play locking plate 15, could be with locking plate 15 disengaged positions, on its unit design real have do not conform to practical situation, in addition improved necessity is more arranged further.

Main purpose of the present utility model is to provide a kind of easy to assembly, makes the bicycle foot rest that automatically locks of the more realistic operation of whole foot rest.

The utility model structure design, it mainly is included in permanent seat one side and cuts the inclined-plane one gap slot is set, and another side is provided with the cylinder of protrusion, and centre then has a bolt can catch on spring; The locking plate of Y-shaped then interlocking on pole, sheet is colluded on the locking plate top, but then there is the outstanding notch of a hook spring bottom, it is characterized in that: cylinder and locking plate upper end that the permanent seat below is provided with protrusion are provided with circular groove, in use by protruding positioning pole and interactive relationship that circular groove produces, the synchronous rotating operation of locking plate and pole when making the foot rest support operation.

A kind of bicycle foot rest that automatically locks of the present utility model mainly is inclined to an oblique angle appearance with the permanent seat bending, and cut the inclined-plane in permanent seat one side one gap slot is set, and in another side protruding positioning pole is set; Then interlocking is on pole for the locking plate of Y-shaped, and the locking plate top ends is colluded sheet, and a corresponding end is provided with circular groove, and the bottom then has a protruding notch can catch on spring, and with the pole interlocking; Utilization circular groove and cylinder against the rotation relation that is produced, make the bicycle quick and convenient unlatching of energy and automatically lock.

For further specifying structure of the present utility model, feature and practical purpose thereof below describe in detail as the back with reference to accompanying drawing:

Fig. 1 is the three-dimensional appearance scheme drawing of known bicycle foot rest.

Fig. 2 is the enforcement illustration of known bicycle foot rest.

Fig. 3 is the three-dimensional appearance scheme drawing of the utility model bicycle foot rest.

Fig. 4 is the enforcement illustration of the utility model bicycle foot rest.

A kind of bicycle foot rest that automatically locks of the present utility model, as shown in Figure 3, constituted by members such as a permanent seat 20, locking plates 30, and with the whole foot rest of bolt, and whole permanent seat 20 is an angle of inclination in the bending of top, bolt 23 places, make foot rest become an oblique angle with bicycle, can park reposefully to guarantee bicycle; By the oval notch 21 in permanent seat 20 upper ends, the whole foot rest of available bolt is on the vehicle frame of back, permanent seat 20 bendings are a bevelled oblique angle appearance, cut the inclined-plane in permanent seat 20 1 sides one gap slot 25 is set, cooperate Y type locking plate 30 to play the engagement location, and being provided with the location cylinder 26 of protrusion in the other end, it is in order to articulate spring 27 that central authorities are provided with outstanding bolt 23; Be provided with an oval salient point 22 in permanent seat 20 1 sides, the bolt 24 of lower end is then in order to reach pole 40 and permanent seat 20 interlockings as rotating shaft device; 30 of locking plates are that the circular arc of Y-shaped is tabular, top one side colludes sheet 31, the top then is provided with the groove 32 of a circular arc appearance, and the bottom has a notch 34 that protrudes spring 27 bottoms can be caught on, and locking plate 30 stage casings connect pole 40 with locking plate 30 and as center of rotation with a bolt 33.

The foot rest that automatically locks of the present utility model is manipulated situation as shown in Figure 4, when regaining foot rest, with locking plate 30 by place, latched position oblique angle be opened into pole 40 upright positions on, then 32 of the circular grooves of locking plate 30 contact with the cylinder 26 of permanent seat 20, and therefore spring 27 is also stretched, and by after this vertical point, then by means of the elastic force of spring 27 along sense of motion, rapidly pole 40 and locking plate 30 are taken on the position of level; And when erecting foot rest, when then turning to permanent seat 20 at angle by level storing position foot rest pole 40, the then end angle, circular groove 32 inboard top of locking plate 30 engaging that just contacts with location cylinder 26 that permanent seat 20 protrudes, be rotated further foot rest then, when going to the upright position, end angle, circular groove 32 inboard top is just being complied with the cylinder face that engaging props up cylinder 26 and is being rotated, and spring 27 shrinks strength because of the elongation that is stretched produces, locking plate 30 is moved to rotation direction, and the tensile-elasticity by spring 27, make the pinning that is meshing with each other of the gap slot 25 that colludes sheet 31 and permanent seat 20 of locking plate 30; The oblique angle that the oval salient point 22 of permanent seat 20 then bends in order to secure seat 20, by the pillar of the oval body of the protrusion of salient point 22 as the oblique angle supporting strength of bending, make whole foot rest when loading, can avoid the oblique angle overflexing of permanent seat 20 bendings, thereby bicycle can more firmly be parked, can not make the angle of bending continue to tilt.

Above-mentioned automatic lock for bicycle of the present utility model is decided the structure of foot rest, the circular groove 32 that utilizes locking plate 30 is by permanent seat 20 cylinders 26 engaging positioning actions, driving locking plate 30 rotates, and when pole 40 and locking plate 30 turn to the upright position, the elastic pulling force that is produced by spring 27, the sheet 31 that colludes of locking plate 30 is meshing with each other with permanent seat 20 gap slots 25, and oval salient point 22 is when more having avoided the bicycle parking loading, be subjected to weight and the bending angle of permanent seat 20 is bent more, cause bicycle entirely not park.
