Fig. 2 is the structural representation at another visual angle of the elastic locking cover in the handlebar column foldable structure of portable bicycle of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art can implement according to this with reference to specification sheets word.
As shown in Figure 1 and Figure 2, the handlebar column foldable structure of portable bicycle of the present invention, comprises the lower pillar stand 21 of upper pillar stand 11 and pivot joint with it.Particularly, can be provided with in the lower end of described upper pillar stand 11 pivoted hole 111, in the upper end of described lower pillar stand 21, be provided with pivoted hole 211, described pivot 14 wore pivoted hole 111 and pivoted hole 211 and upper pillar stand 11 and lower pillar stand 21 was articulated, and was tightened by screw 16.Described upper pillar stand 11 can be arranged to inclined-plane with the pivot joint contact surface of described lower pillar stand 21, as shown in Figure 1, in the lower end of described upper pillar stand 11, pin connected assembly 113 is set, and the lower surface of described pin connected assembly 113 is inclined-plane 112; In the upper end of described lower pillar stand 21, pin connected assembly 213 is set, the upper surface of described pin connected assembly 213 is inclined-plane 212, utilizes the cooperation on 112Yu inclined-plane, inclined-plane 212 and guarantees the pivot joint compactness of upper pillar stand 11 and lower pillar stand 21.
In the present invention, at described upper pillar stand 11, be provided with restriction protrusion 114, described lower pillar stand 21 is provided with clamping projection 214.Also be included in the sheathed rotatable elastic locking cover 17 in periphery of the articulated section of described upper pillar stand 11 and lower pillar stand 21, the upper end of described elastic locking cover 17 is provided with limited location snap ring (not shown), and the lower end of described elastic locking cover 17 is provided with clamping snap ring; When described upper pillar stand 11 is with described lower pillar stand 21 pivot joints and while being same straight line, limited location snap ring and the described restriction protrusion 114 of described elastic locking cover 17 offset, and described elastic locking overlaps 17 clamping snap ring and described clamping projection 214 and offsets.Described limited location snap ring imposes the power of downward direction to restriction protrusion 114, described clamping snap ring imposes the power of upward direction to clamping projection 214, thereby by means of the fastening force of these 17 pairs of upper pillar stands 11 of elastic locking cover and lower pillar stand 21, make described upper pillar stand 11 and lower pillar stand 21 keep the state that joins of straight line.
In the present invention, described elastic locking cover 17 is rotatable, for this reason, in the inside of described elastic locking cover 17, is provided with storage tank (not shown), is provided with torque spring 15 in described storage tank; One end of described torque spring 15 is fixedly connected with described upper pillar stand 11, the other end is fixedly connected with described elastic locking cover 17, like this, just described elastic locking cover 17 is imposed to a rotational force all the time, make described elastic locking cover 17 keep the state screwing with respect to upper pillar stand 11.In the present invention, the contact surface that described clamping snap ring and described clamping projection 214 offset is set to helical surface, like this, just can overlap by elastic locking 17 rotational force, the clamping snap ring of elastic locking cover 17 and the clamping projection 214 of lower pillar stand 21 are closely offseted all the time, to guarantee the fastening force of 17 pairs of upper pillar stands 11 of elastic locking cover and lower pillar stand 21.
In the present invention, also at described clamping snap ring, be provided with breach 172, this breach 172 is divided into two parts (being be denoted as 173 part in Fig. 2 and be denoted as 174 part) by described clamping snap ring, and the size of described breach 172 is corresponding with described clamping projection 214.When needs upper pillar stand 11 is separated with lower pillar stand 21 and when folding, by described breach 172 over against clamping projection 214, because the size of this breach 172 is corresponding with the size of described clamping projection 214, therefore, described clamping projection 214 can be passed in this breach 172, even also the clamping snap ring of the lower end of elastic locking cover 17 no longer contacts with clamping projection 214, like this, upper pillar stand 11 is just no longer subject to elastic locking with lower pillar stand 21 and overlaps 17 fastening force, is free to be folded into parastate.When needs are ridden, while needing upper pillar stand 11 and lower pillar stand 21 to be straight line, make described breach 172 miss clamping projection 214, even 173 parts of clamping snap ring or 174 parts and described clamping projection 214 offset.
Column stability in order to guarantee to ride, also the sidewall at described elastic locking cover 17 offers longitudinal slotted hole 171; Meanwhile, be also provided with elasticity jump pearl at described upper pillar stand 11, when described upper pillar stand 11 is with described lower pillar stand 21 pivot joints and while being same straight line, described elasticity is jumped the top of pearl in described longitudinal slotted hole 171.That is to say, by described elasticity, jumping pearl realizes upper pillar stand 11 relative fixing with the position of elastic locking cover 17 with the cooperation of described longitudinal slotted hole 171, in actual applications, described longitudinal slotted hole 171 also needs to consider horizontal surplus, so that elastic locking cover 17 also can be guaranteed elasticity when adjusting locked position, jumps pearl and is positioned at longitudinal slotted hole 171.
As shown in Figure 1, particularly, described elasticity is jumped pearl can comprise jumping pearl 13 and spring 12, and described jumping pearl 13 is arranged at upper pillar stand 11 by spring 12.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in specification sheets and embodiment, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend of describing.
