Description
The utility model relates to a kind of registration device of bicycle base riser, and particularly a kind of registration device of being convenient to adjust the base riser of seat cushion position mainly is to utilize orienting lug, blocking pin fit adjustment seat to assemble; The pedestal of seat cushion, loam cake are respectively settled orienting lug at opposite face, and the location is adjusted seat and worn orienting lug, adjusts seat with the blocking pin embedding of orienting lug, make and adjust seat along the orientation of orienting lug slippage with the adjustment seat cushion, and good location, directionality is provided.
Bicycle is equipped with seat cushion for people's saddle horse, and seat cushion normally has hack lever with in the relevant setting of abutment pipe by the seat cushion bottom surface with the combination of seat pipe, following seat folder is established, and make seat cushion be able to the fore-and-aft adjustment height, the current base riser combined structure that has a kind of than novelty, as the Taiwan patent announcement number is 22663 No. three " cushion standpipe structural improvement " (be designated hereinafter simply as patent before case), its structure is shown in accompanying drawing 8~10, it is at loam cake 6 and adjusts the hack lever that inserts and puts seat cushion between the seat 4 and stride the setting position, adjust angular way, adopt spring 5 bottom hooks to put on pedestal 3 in-to-in latches 312, the top hook fixes on the post tip 45 that raises in the bed rearrangement 4, loam cake 6 both sides each with pedestal 3 collocation one bolt, the cylinder of tool screw, members such as semicylinder give spiral shell and wear the location; Revolve as angle along pedestal 3 adjusting that seat 4 utilizes spring 5 and to move, after adjusting, again at pedestal 3 with adjust seat 4 both sides and give screw lock and fix; But there is following shortcoming in this structure.
(1) utilize spring 5 as adjustable activity space, cause spring 5 very easily to can't bear to use because of elastic fatigue, there is the situation of rocking to be difficult for directed on the contrary when adjustment being arranged if the Flexible Design of spring 5 is lax, if spring 5 tensions then cause resistance, be difficult to adjust, therefore utilize spring 5 to adjust radian, have poor durability, the problem that the location is unstable as adjusting seat 4.
(2) pedestal 3 is with to adjust related elements such as seat 4 both sides barrel bolt too various, and needs both sides locking, both sides to unclamp, and increases the adjustment time, and element is many and complicated, increases cost.
Main purpose of the present utility model is to provide a kind of registration device that can overcome the bicycle base riser of above-mentioned shortcoming, mainly is to cooperate the assembling of adjusting seat, blocking pin; Utilize the embedding of blocking pin to wear orienting lug, adjustment seat, make and adjust seat in adjusting angle, cooperation blocking pin is shifted along the slip hole track, reaches to have preferable directionality when adjusting seat cushion.
The technical solution of the utility model is:
At opposite face slip hole is set at pedestal, loam cake, expands groove or settles the orienting lug that has slip hole, expands groove, be used to make and adjust the blocking pin that seat and orienting lug are located, embedding is worn orienting lug, is adjusted seat, cooperates the blocking pin to be shifted along the slip hole track, reaches the purpose of adjusting the seat cushion orientation.
The concrete structure of the registration device of bicycle base riser of the present utility model is as follows:
It comprises a pedestal, an adjustment seat, a loam cake, a hack lever, an orienting lug and a blocking pin, its assembling mode: foot-operated saddle tube end face is a pedestal, and pedestal is an arcs of recesses, for adjusting the seat location, adjust seat again the hack lever of rebasing of abutment stride and put, loam cake is located at adjusts a seat end face;
Loam cake can compel relatively to close and unclamp on described pedestal, and the end face of loam cake runs through a microscler slip hole, with the tapering blocking that cooperates the blocking pin wherein;
Pedestal opposite face central authorities evenly settle described orienting lug, and this orienting lug is that an arc block runs through microscler slip hole together at end face with parallel hack lever direction, and bigger expansion groove is established in position, the tapering expansion of the relative blocking pin of the slip hole all sides of one side;
One cooperates the location to adjust the blocking pin of seat and orienting lug, and it is the tapering that a short nail body is at one end established the tool pushing and drawing shape, and side face is all offered several gaps bottom the tapering;
Adjust seat and comprise upper and lower seat, upper and lower seat central authorities orienting lug relatively run through and establish a perforation, so as to cooperating the blocking pin through upper and lower seat and orienting lug is worn in embedding, adjust the position of seat cushion together with the displacement of blocking pin in order to adjusting seat.
Described loam cake settles the tapering can be arranged with more large-area expansion groove at microscler slip hole relatively, to cooperate the arrangement of blocking pin.
Described pedestal one end can be offered breach, the other end can be equipped with the protruding end and be pivoted for loam cake, and each relative breach of loam cake and protruding end respectively are provided with wing groove, and the wing groove of breach is worn for the excellent pivot of wearing of a tool screw relatively, make bolt be plugged on breach and spiral shell is worn rod, adjust seat with clamping.
Described pedestal end face can be arranged with a groove to settle orienting lug.
The utility model and traditional registration device relatively have following effect:
Polarization, directionality that 1 the utility model is adjusted are preferable: utilize the blocking pin to be fastened in the orienting lug, the blocking pin wears and adjusts seat again, make hack lever can have a directional tagging together with the adjustment angle of adjusting seat, especially the blocking pin is limited to the directed displacement of expansion groove of orienting lug, form directed really track effect, on adjusting, be difficult for rocking and be adjusted to easily and need angle.
2 adjust before and after, only need unclamp or the packing bolt get final product, need not both sides and adjust degree of tightness, and element constitutes and quite simplifies, easy to manufacture, be convenient to operate, with low cost.
3 orienting lugs and blocking pin, adjustment toilet are in blocking, especially utilize the tapering tool pushing and drawing shape of blocking pin, and the thick subdivision of peripheral meat is gapped to be convenient to quick assembling by approaching dwindling in the middle of assembling, after packing into, because of the gradient in tapering in addition the gap mutually away from restoring to the original state outer in the past expanded support, resist the slip hole that expands groove and be difficult to extract orienting lug, guarantee blocking pin stack-mounted stability, also so further ensure the directed convenience of seat cushion adjustment angle.
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
