Abstract

The utility model relates to a folding bicycle pedal. The folding bicycle pedal contains a frame body; a block body is connected in the frame bottom; a circular hole is axially penetrated through the block body; a bar hole is penetrated downward through the top surface of the block body to be vertically connected to the circular hole; a spring and a circular are arranged in the circular pipe; the pipe surface of the circular pipe is provided with a through hole which is inserted by a couple of T-shaped fasteners from the bar hole; a connecting body is pivoted at the opening position of the frame; a shaft hole is arranged in the connecting body; the head end of the shaft hole is axially provided with a shaft lever and the tail end can be just sleeved on the circular pipe which is positioned by the contacting of the spring; when the T-shaped fastener slides and presses to the frame body, which can make the circular pipe leave the shaft hole to fold the frame body; hereby, the goal of increasing the safe using of the folding bicycle pedal is obtained.

Description

The Folding Bicycle pedal

The utility model is the structural improvement of relevant a kind of bicycle pedal, refers in particular to a kind of structural improvement of Folding Bicycle pedal that can 90 degree foldings, and the structure of its innovation of mat is promoted purpose safe in utilization and can reach.

The angle that bicycle is played the part of in the modern life gradually by the main vehicle then for recreation tool, is loaded onto the field with it and exercises with luxuriant again and be a kind of general mood, and for ease of the carrying of vehicle, the structure of removable group or folding is to educate pregnant and give birth to.

See also Fig. 1 and Fig. 2, it is a kind of Folding Bicycle pedal commonly used, it has a Contraband word shaped as frame body 1, its end face is connected with a top board 2, top board 2 is provided with a breach, the frame oral area position of body 1 is provided with corresponding screw, other establishes a convex union body 3,31 ones on its protruding top just can be placed in the breach, the bottom of whole union body 3 then just can be contained within the shaped as frame of body 1, union body 3 both sides and screw corresponding position are provided with perforation, and give bolt with bolt 5 and close pivot joint, are provided with an axis hole in the union body 4, its built-in bearing can be nested with for an axostylus axostyle 6, axostylus axostyle 6 outer ends then have screw thread can with crank lock knot, mat bolt 5 can make body 1 upwards folding for the axle center, receives the function of folding and reach.

The shaped as frame ectosome 1 of above-mentioned Folding Bicycle pedal commonly used, when its horizontal is used, be to make its location by top board 2 abuts against union body 3, so need to keep protruding top 31 supine running conditions,, then will make body 1 because of there not being the bending of dropping of supporting downwards if oppositely, and bicycle often loiters when driving, one has then promptly very easily to cause accidentally and steps on sky and to cause centre-of gravity shift to produce dangerous, and the doubt that its structure is produced on safety remains to be improved in fact.

Its structure of Folding Bicycle pedal commonly used has aforesaid shortcoming on using, therefore how to research and develop new structure to overcome above-mentioned shortcoming, is manufacturing important topic in fact.

Therefore, main purpose of the present utility model is: a kind of Folding Bicycle pedal that increases safety in utilization is provided, it has a three-sides-square shape frame body, frame inner bottom part interlocking one rectangle block, a circular hole has crossed in block central authorities, in addition from the block end face down run through a strip hole and with the circular hole vertical connection, a spring and a pipe have been inserted in the circular hole in regular turn, tool perforation and insert from strip hole on the pipe pipe face with a pair of T shape fastener, and the head end that makes pipe is exposed to outside the circular hole, frame mouth place articulates a union body, has axis hole in the union body, in the axis hole of one end with the bearing axostylus axostyle that is pivoted, and make axostylus axostyle protrude axis hole for interlocking in crank, but the union body axis hole proper fit pipe then of end in addition, and replacing of mat spring makes its location, when with T shape fastener at the bottom of the frame during sliding pressure, can make pipe recess axis hole and the framework folding can be reached by this and promoted Folding Bicycle pedal purpose safe in utilization.

For further specifying structure of the present utility model, feature and practical purpose thereof are described in detail as follows in conjunction with following accompanying drawing:

Fig. 1 is the External view of Folding Bicycle pedal commonly used.

Fig. 2 is the folded state diagram of Folding Bicycle pedal commonly used.

Fig. 3 is the External view of the utility model Folding Bicycle pedal.

Fig. 4 is the exploded drawings of the utility model Folding Bicycle pedal.

See also Fig. 3 and Fig. 4, Folding Bicycle pedal of the present utility model, it has a three-sides-square shape frame body 10, frame inner bottom part driving fit interlocking has a rectangle block 11, a circular hole 12 crosses in block 11 central authorities, in addition from block 11 end faces down be penetrated with a strip hole 13 and with circular hole 12 vertical connections, a compression spring 15 and a metal circular tube 16 have been inserted in the circular hole 12 in regular turn, spring 15 and the external diameter of pipe 16 are apertures of corresponding circular hole 12 and being set as, make pipe 16 can effectively support location pressing spring 15, has a perforation 17 on the pipe 16 pipe faces, and it is vertical corresponding with the position of strip hole 13, and with a pair of T shape fastener 18,19 from block 11 tops, the bottom surface is inserted strip hole 13 and perforation 17 respectively, spring 15 and pipe 16 are positioned in the circular hole 12, and the head end that makes pipe 16 is exposed to outside the circular hole 12, the edge at body 10 frame mouth places is provided with two corresponding perforation 20, other is provided with a T shape union body 21, the head of its cross bar shape just can be placed in two edges of body 10, cross the perforation 22 of a corresponding perforation 20 in the head, and with one group of screw rod 23 place the perforation 20 with perforation 22, union body 21 can be articulated on the body 10, tool axis hole 25 in the union body 21, the one end is hubbed at an axostylus axostyle 24 in the axis hole with a bearing, the bared end tool screw thread of axostylus axostyle 24 and for interlocking in crank, but 25 proper fit pipes 16 of the axis hole of union body 21 tail ends, and replacing of mat spring 15 makes its location, when with T shape fastener 18,19 at the bottom of the frames during sliding pressure, can make pipe 16 recess axis hole 25 and can be with the framework folding.

Body 10 of the present utility model, when its horizontal is used, be to replace pipe 16 by spring 15 to be inserted in the union body 21 and to make its location, it is no matter under the running condition of any angle, body 10 is located and do not have the doubt of bending, can effectively improve the person's of commonly using disappearance, and promote the safe in utilization of Folding Bicycle pedal.
