Abstract
The invention discloses a connecting rod. The connecting rod comprises a connecting rod large end, a rod body and a connecting rod small end, the connecting rod large end is connected with the connecting rod small end through the rod body; the connecting rod large end is provided with a transmission shaft mounting hole, and the connecting rod small end is provided with a pinhole; and the pinhole at the connecting rod small end is a blind hole, two slots are symmetrically arranged at the bottom portion of the pinhole, and each of the slots is perpendicular to the pinhole. When the connecting rod is assembled with a matched connecting rod pin, the elastic buckles of the connecting rod bin are pressed to fill the connecting rod pin into the pinhole at the connecting rod small end until the bottom portion of the pinhole, the elastic buckles are clamped in the slots under the action of elastic restoring force, and the axial fixity between the connecting rod pin and the connecting rod is realized through the elastic buckles to transmit torque. When dismounted, the elastic buckles are pressed, so the connecting rod pin is outwardly dragged out. The connecting rod has the advantages of simple structure, reasonable design, and easy mounting and dismounting.
Description
Technical field
The present invention relates to a kind of improvement of parts of driving mechanism, particularly a kind of easy-disassembling-assembling bicycle use connecting rod.
Background technique
Connecting rod mechanism movement is various informative, can realize the compound movements such as rotation, swing and movement in plane and the space, and therefore, linkage mechanism is widely used in various machineries, instrument and electronic product.Connecting rod be in the linkage mechanism two ends respectively with the hinged rod member that transmits motion and power of dirivig member and driven member.Be exactly by connecting rod the power that wood clapper bears to be passed to transmission shaft as bicycle, and then drive the drive chain running, finally realize the front and back running of wheel.The small end of connecting rod is provided with pin-and-hole, by pin wood clapper is connected on the wrist-pin end of connecting rod.The pin of bicycle use and the pin-and-hole on the wrist-pin end of connecting rod all are to adopt interference fit at present, the assembling difficulty, to fit dimension required precision height, and connect to need very big external force owing to take interference apart, tend to damage the matching surface of part in the connection and cause and to utilize again.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of easy-disassembling-assembling bicycle use connecting rod.
Technical solution of the present invention is achieved in that a kind of connecting rod, comprises connecting rod tip, and shaft and wrist-pin end of connecting rod connect by shaft between described connecting rod tip and the wrist-pin end of connecting rod; Described connecting rod tip is provided with the transmission shaft mounting hole, and described wrist-pin end of connecting rod is provided with pin-and-hole; The pin-and-hole of described wrist-pin end of connecting rod is blind hole, and described blind-hole bottom portion is symmetrically arranged with two draw-in grooves.
Preferably, described each draw-in groove is perpendicular to described pin-and-hole.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Connecting rod of the present invention comprises connecting rod tip, and shaft and wrist-pin end of connecting rod connect by shaft between described connecting rod tip and the wrist-pin end of connecting rod; Described connecting rod tip is provided with the transmission shaft mounting hole, and described wrist-pin end of connecting rod is provided with pin-and-hole; The pin-and-hole of described wrist-pin end of connecting rod is blind hole, and described blind-hole bottom portion is symmetrically arranged with two draw-in grooves; Described each draw-in groove is perpendicular to described pin-and-hole.When connecting rod of the present invention assembles with the link pin that matches mutually, the Elastic buckle of pressing described link pin is packed link pin the pin-and-hole of wrist-pin end of connecting rod into until the pin-and-hole bottom, described Elastic buckle snaps under the effect of elastic-restoring force in the described draw-in groove, realizes that by Elastic buckle axial restraint between link pin and the connecting rod is with transmitting torque.During dismounting, press Elastic buckle and link pin outwards can be pulled out.Bar linkage structure of the present invention is simple, and is reasonable in design, easy accessibility.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the plan view of connecting rod of the present invention;
Accompanying drawing 2 is the sectional view of connecting rod of the present invention;
Exploded view when accompanying drawing 3 is connecting rod application state of the present invention;
Wherein: 1, connecting rod tip; 2, shaft; 3, wrist-pin end of connecting rod, 4, the transmission shaft mounting hole; 5, pin-and-hole; 6, draw-in groove; 7, link pin; 8, Elastic buckle; 9, connecting rod.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of bicycle use connecting rod of the present invention as accompanying drawing 1,2, comprise connecting rod tip 1, shaft 2 and wrist-pin end of connecting rod 3 connect by shaft 2 between described connecting rod tip 1 and the wrist-pin end of connecting rod 3; Described connecting rod tip 1 is provided with transmission shaft mounting hole 4, and described wrist-pin end of connecting rod 3 is provided with pin-and-hole 5; The pin-and-hole 5 of described wrist-pin end of connecting rod 3 is blind hole, and described pin-and-hole bottom is symmetrically arranged with two draw-in grooves 6; Described each 6 perpendicular to described pin-and-hole 5.
Exploded view when being connecting rod application state of the present invention as shown in Figure 3, the end, two ends of described link pin 7 all is symmetrically arranged with Elastic buckle 8, the Elastic buckle 8 of pressing an end is wherein packed link pin 7 pin-and-hole 5 of wrist-pin end of connecting rod 3 into until the pin-and-hole bottom, described Elastic buckle 8 snaps under the effect of elastic-restoring force in the described draw-in groove 6, realizes that by Elastic buckle 8 axial restraint between link pins 7 and the connecting rod 9 is with transmitting torque.During dismounting, because Elastic buckle 8 usefulness at the two end part of link pin 7 is to use same elastic device, the Elastic buckle 8 of pressing link pin 7 the other ends makes the elasticity card 8 that is embedded in the draw-in groove 6 break away from draw-in groove 6, link pin 7 is pulled outwardly namely detachable.Bar linkage structure of the present invention is simple, and is reasonable in design, easy accessibility.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
