Detailed Description
To make the objects, technical solutions and advantages of the present invention more clearly understood, the following description is given for further details of the present invention with reference to the accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention, and are not intended to limit the present invention. It should be noted that the present invention is already in practical development and use stage.
The present invention will be described in further detail with reference to examples.
Example 1
As shown in the figure, this embodiment includes heel brace bracing piece 1, heel brace sleeve 2 includes that open end and blind end and inside have and hold the cavity, the open end cover is established the one end of heel brace bracing piece 1, the one end that heel brace bracing piece 1 is connected with heel brace sleeve 2 is provided with a plurality of screw holes 4, is equipped with the trompil on the section of thick bamboo wall of heel brace sleeve 2, with 4 matched with bracing piece screws 3 of screw hole pass behind the trompil with 4 spiro couplings of screw hole.
The specific operation process of this embodiment is as follows: whether the road surface of a section where the balance car is parked is flat or not is determined firstly, if the balance car is parked on a sloping field stably, the foot supports need to be correspondingly heightened or lowered, and the length of the foot supports needing to be adjusted is determined according to the steepness degree of the sloping field. Preferably, in this embodiment, three equidistant threaded holes 4 are formed in one end of the temple support rod 1 connected to the temple sleeve 2, an opening with the same aperture is formed in the wall of the temple sleeve 2, and the support rod screw 3 penetrates through the opening and then is screwed with one of the threaded holes 4 of the temple support rod 1. When the length of the foot support needs to be adjusted, the supporting rod screw 3 is only required to be unscrewed, then the supporting rod screw 3 is pushed or stretched towards the axis direction of the foot support sleeve 2, and when the supporting rod is adjusted to a proper position (namely, the threaded hole 4 on the foot support supporting rod 1 corresponds to the open hole on the foot support sleeve 2), the supporting rod screw 3 is screwed down, so that the purpose of adjusting the height of the foot support is achieved. In order to enlarge the adjustable range of the foot support, the number of the threaded holes 4 can be correspondingly increased to adapt to normal use under different scenes.
It should be noted that the threaded hole 4 can only realize point-to-point adjustment, and in order to realize a linear adjustment function, the threaded hole 4 may also be a sliding groove penetrating through the temple support rod 1, and is fixed by a bolt and a nut in a matching manner. The opening formed in the cylinder wall of the foot support sleeve 2 needs to be communicated, and the bolt penetrates through the cylinder wall, the sliding groove and the cylinder wall on the other side in sequence and then is screwed up and fixed by the nut. The structure can realize linear adjustment, has wider adjustment range and meets more use scenes.
In order to maintain the corresponding state of the foot support after the unfolding state and the accommodating state are mutually switched, the closed end of the foot support sleeve 2 is also provided with a lock control mechanism.
Furthermore, a foot support spring 5 is further arranged in the containing cavity of the foot support sleeve 2, and two ends of the foot support spring 5 are respectively abutted against the foot support rod 1 and the lock control mechanism. The spring has an extrusion force to the heel brace supporting rod 1, so that labor is saved when the heel brace supporting rod 1 needs to be taken down.
Furthermore, lock accuse mechanism includes heel brace locking piece 9 and locking piece screw 7, heel brace locking piece 9 sets up in the blind end cavity of heel brace sleeve 2 and heel brace locking piece 9 middle part is equipped with the through-hole, and locking piece screw 7 runs through behind the through-hole with heel brace sleeve 2 fixed connection, still be equipped with heel brace slider 6 between heel brace locking piece 9 and heel brace spring 5. The cavity that holds of 2 blind ends of heel brace sleeve sets up heel brace locking piece 9, heel brace slider 6 and heel brace spring 5 with this in, and under the initial condition, heel brace spring 5 has small compression capacity, therefore heel brace spring 5 has certain extrusion force to heel brace slider 6 for heel brace slider 6 and 9 butts of heel brace locking piece.
It should be noted here that the cross section of the foot supporting locking piece 9 is circular, and the outer peripheral wall thereof is provided with two mutually perpendicular planes, and a convex ridge 91 is formed at the intersection of the two planes. At this time, the whole support lock block 9 is of a diameter-variable structure, that is, when the support rod 1 is rotated by switching the unfolding state and the storage state of the support, the support lock block 9 is fixed, the support rotates around the central point of the support lock block 9, the rib 91 extrudes the support slide block 6, as shown in fig. 2, the distance from the tangent point of the support slide block 6 and the support lock block 9 to the center of the rotation circle of the support lock block 9 is increased and then decreased (i.e., S2 > S1= S3), and the rotation is stopped when the support slide block rotates to another plane; due to the presence of the rib 91 and the pressing force of the spring in the sleeve against the footrest slide 6, the footrest can be maintained in the unfolded or folded state without rotating the footrest support bar 1 by an external force.
In order to stop the rotation of the foot support rod 1 when the foot support rod rotates to the unfolding state or the storage state, the closed end of the foot support sleeve 2 is further provided with a foot support seat 8, and the foot support seat 8 comprises a first limiting portion 81 and a second limiting portion 82. And the first 81 and second 81 limiting parts are perpendicular to each other. When the foot support is in the unfolding state, the first limiting part 81 can limit the foot support supporting rod 1 to continuously rotate downwards; similarly, when the foot support is in the storage state, the second limiting portion 82 can limit the foot support rod 1 to continue to rotate upward.
Preferably, a fixing portion 111 is disposed at an end of the temple support bar 1 away from the temple sleeve 2. The fixing portion 111 is parallel to the ground, providing a more stable supporting effect.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
