Abstract
A front and back lock type bicycle saddle pad combined device comprises a cushion bar, a clip set situated at the top of the cushion bar and a locking block under the cushion bar. A jointing part is arranged at the top of the cushion bar and two fore-and-aft distributed elongated grooves which are arranged at the middle of the jointing part are used for fixing the two fixing bolts in a spiral form at the clip set through the lower locking block and the elongated groove. Because the two fixing bolts are distributed backwards and forwards without passing through the arc center of the joining part, an anti-force arm can be generated. When the cushion receives the weight of a rider, the moment of resistance is generated to resist the sliding force and generate the anti-sliding effect.
Description
Technical field
The utility model relates to a kind of bicycle part, relates in particular to a kind of front and back locking-type bicycle saddle cushion combining device.
Background technology
The vehicle frame top of bicycle is plugged with a seat cushion bar, so as to the top junction unification seat cushion of present lining bar.And the form of existing bike saddle lining bar on the whole as shown in Figure 4, the center of top of seat cushion bar 50 places spiral shell with a screw rod 51 and establishes an intermediate plate group 60 of being made up of upper and lower intermediate plate 61,62, and the left and right sides of this intermediate plate group 60 clipping one respectively is positioned at the inserted link 71 of seat cushion 70 bottoms.Again, for convenience the rider adjusts suitable seat cushion 70 angles, so be curved the cooperation between seat cushion bar 50 apical margins and the lower clamping piece 62, establishes the elongated slot that a confession screw rod 51 places again on this arc apical margin, whereby, the rider promptly can be adjusted into the angle of depression or the elevation angle with seat cushion 70.
Yet, when driving, can force in inserted link 71, intermediate plate group 60, because the slip of its friction force opposing intermediate plate group 60 that only produces by the coupling mechanism force of a screw rod 51, so it is tight and make seat cushion 70 situations of slips arbitrarily that lock very easily takes place in this kind seat cushion 70.
As shown in Figure 5, be the form of another kind of existing seat cushion bar 80, its apical margin cooperates with the bottom of intermediate plate group 81 is curved, places screw lock in intermediate plate group 81 with a screw rod 82,83 respectively in the left and right sides of seat cushion bar 80 in addition.Though it is provided with two screw rods 82,83 to promote skidproof effect.Yet, because being fore-and-aft direction, the arc of seat cushion bar 80 apical margins tilts, the seat cushion (not shown) then can be adjusted in the front and back slip, two screw rods 82,83 then is to be listed in the left and right sides by the arc center, so when bearing rider's weight, the moment that can't create antagonism and slide is for the effect that promotes the slip of opposing seat cushion and little.
The utility model content
In order to overcome the above-mentioned shortcoming that existing bicycle saddle cushion exists, the utility model provides a kind of front and back locking-type bicycle saddle cushion combining device that can improve skidproof effect.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of front and back locking-type bicycle saddle cushion combining device, the top of bike saddle lining bar has big curved arc shape joint portion, the seat cushion bar is according to the headstock of bicycle, before tailstock direction is defined as, the rear end, apical margin in the joint portion is provided with an intermediate plate group, be fixed in the intermediate plate group left and right sides so as to two inserted links with seat cushion, it is characterized in that: in the middle of the joint portion of present lining bar, be provided with two microscler grooves of wearing that distribute before and after being, establish lock dog in seat cushion bar below in addition, the apical margin of this time lock dog is identical with the curvature of the root edge of joint portion, and the front and back end is respectively equipped with a perforation in the middle of following lock dog, and other establishes two perforation of passing down lock dog, joint portion microscler worn the bolt of rear end plate that groove is fixed at the intermediate plate group again.
Aforesaid front and back locking-type bicycle saddle cushion combining device wherein descends the apical margin of lock dog to be provided with the tread plate that several extends towards the left and right sides.
Aforesaid front and back locking-type bicycle saddle cushion combining device, wherein the joint portion of seat cushion bar is the low and middle high curved arc shape in rear and front end.
By above-mentioned technological means, the utility model is owing to two bolt of rear end plates lockings that distribute by front and back, when seat cushion bears rider's weight and slides, can be because two bolt of rear end plates pass through the arc center of joint portion, slide with opposing and produce the opposite resisting moment of a direction respectively, promote skidproof effect.
