Description
Technical field
The utility model relates to a kind of bicycle use with the fixing fixed sturcture of seat cushion, is meant the bicycle saddle cushion fixed sturcture that a kind of structure is firm, assembling is quick, safe in utilization especially.
Background technology
As shown in Figures 1 and 2, existing bicycle saddle cushion fixed sturcture, wherein, seat cushion (among the figure indicate) bottom at least and show two poles 10,10 places are provided with a link block 20 in two poles, and cycle frame (indicating among the figure) has then extended upward a pipe 30, and the top of present pipe 30 is provided with a joint 40 that engages with link block 20 formations, see through in addition two bolts 50 with link block 20 and joint 40 interlocking mutually, combine with a locking of managing 30 to constitute seat cushion.
Wherein, link block 20 by upper and lower intermediate plate 21,22 with pole 10 clippings, upper clamping piece, lower clamping piece 21,22 appropriate positions are respectively arranged with screw 23 and interlocking hole 24, its screw 23 can be for each bolt 50 locking, 40 of its joints are provided with an interlocking hole 41 that supplies bolt 50 to wear, and with when bolt 50 is locked with screw 23, can pole 10 be clamped by upper and lower intermediate plate 21,22, and together with link block 20 and joint 40 are clamped, with top with the present pipe 30 of seat cushion locking.
In addition, be the curved arc shape and be provided with a plurality of roller seating spaces 61,, reach the purpose of regulating the seat cushion angle by the corresponding engage position of change link block 20 with joint 40 in the joint place of joint 40 with lower clamping piece 22.
Existing seat cushion fixed sturcture produces following defective:
One, only combines between link block 20 and the joint 40 by the wearing the lock effect of bolt 50, promptly, except bolt 50, any auxiliary coupling arrangement is not arranged, adding that this bolt 50 is as easy as rolling off a log ruptures because being subjected to the tension between link block 20 and the joint 40, therefore, might when the seat pipe of car body comes off, tend to the rider is damaged because of the gravity compressing of moment or impact effect when the seat cushion of bicycle.
Two, when overall package, two poles are placed on the lower clamping piece earlier, again upper clamping piece is placed in two poles top, and upper and lower intermediate plate is placed on the joint with pole, need this moment with the screw in upper and lower intermediate plate and the joint and interlocking hole mutual involutory after, just bolt can be worn and is locked in the screw, and then upper and lower intermediate plate is clamped pole; This kind assembling mode not only comparatively bothers, and the locking of each bolt all need be carried out the involutory, very consuming time of three holes (screw and two interlocking holes).
The utility model content
Technical problem to be solved in the utility model is: a kind of bicycle saddle cushion fixed sturcture is provided, and it can finish the assembling of seat cushion and seat pipe fast.
Another technical matters to be solved in the utility model is: a kind of bicycle saddle cushion fixed sturcture is provided, and it can prevent that each bolt from because of long-term or improper use the danger that fracture causes seat cushion and seat pipe to break away from taking place.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bicycle saddle cushion fixed sturcture, its seat cushion bottom is provided with two poles at least side by side, its cycle frame has extended upward a pipe, the top of present pipe is provided with a link block and joint, see through at least two bolts with link block and joint interlocking mutually, combine with the locking of a pipe to constitute seat cushion; Be provided with a plurality of roller seating spaces that are involutory between this link block and joint; Have additional the perforation that is involutory between link block and joint and stretch into for bar, and perforation one side that bar stretches into joint is provided with connecting element, bar passes link block and joint and interfixes with connecting element.
The beneficial effects of the utility model are: when one, assembling, only needing this upper clamping piece is that fixed end rotates a special angle with the bar, each pole is placed on the lower clamping piece, again upper clamping piece is rotated to the position of lower clamping piece with the pole clipping after, can be directly see through bolt with link block and joint interlocking mutually, save the time of involutory hole, can finish the assembling of seat cushion and seat pipe fast; Two, when fracture takes place because of long-term or improper use in bolt, can still constitute being connected of link block and joint by bar, prevent the danger that seat cushion and the disengaging of seat pipe cause.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
The utility model bicycle saddle cushion fixed sturcture, the basic structure of whole seat cushion fixed sturcture is formed as Fig. 3 to shown in Figure 5, its seat cushion (among the figure indicate) bottom at least and show two poles 10, cycle frame (not indicating among the figure) has then extended upward a pipe 30, the top of present pipe 30 is provided with a link block 20 and joint 40, see through at least two bolts 50 with link block 20 and joint 40 interlocking mutually, combine with a locking of managing 30 to constitute seat cushion.
Wherein, link block 20 by upper and lower intermediate plate 21,22 with pole 10 clippings, upper clamping piece, lower clamping piece 21,22 appropriate positions are respectively arranged with screw 23 and interlocking hole 24, and its screw 23 can be for each bolt 50 locking, and 40 of its joints are provided with an interlocking hole 41 that supplies bolt 50 to wear.
Wherein, be provided with a plurality of roller seating spaces that are involutory between this link block and joint, the joint place of these lower clamping piece 22 bottom surfaces and joint 40 is the curved arc shape, and be provided with a plurality of roller seating spaces that are involutory 61, and 40 of link block 20 and joints are provided with perforation 62 and the groove 42 that is involutory, bar 71 then stretches into perforation 62 and groove 42 interfixes with connecting element 72, and on, lower clamping piece 21,22 and be provided with an elastic parts 73 (its elastic parts can be spring), its elastic parts 73 also is sheathed on the bar 71, as shown in Figure 6, make bar 71 be passed link block 20 and interfix with connecting element 72, going up with joint 40, lower clamping piece 21,22 interconnect with joint 40; In addition, this connecting element 72 also can wear for two bolts 50 simultaneously, as Figure 10 and shown in Figure 11.
