Description
Technical field
The utility model belongs to automatic locking technical field of structures, particularly a kind of self-closing fastener.
background technique:
Current is be fixed up by pin by the base of one of them connecting rod in quadratic crank mechanism and quadratic crank mechanism to the locking of quadratic crank mechanism, and this fixing operation is cumbersome, also easily crushes the finger of operator.Or one of them connecting rod in quadratic crank mechanism is provided with connecting rod be connected with the face of stepping on; Be exactly arrange a strut in addition, the structure on they sup-port ground is not very stable.
Model utility content
The purpose of this utility model is that safety coefficient is high in order to provide easy to operate, constitutionally stable self-closing fastener.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of self-closing fastener, comprise fastener body and the dunnage that described fastener body is set, described dunnage is provided with the supporting foot coordinating described fastener body, described fastener body comprises the projecting shaft for engaging described supporting foot, described projecting shaft is provided with the first elastic structure and coordinates with described dunnage and regulate described projecting shaft and described supporting foot tap.
As preferably, described fastener body is provided with outer cover body, described outer cover body and described dunnage as a whole; Be equipped with driven shaft in described outer cover body, described driven shaft front end is connected with coupling shaft, and described coupling shaft front end is fixedly connected with button; Described driven shaft rear end is connected with transmission shaft, and described transmission shaft rear end is provided with described projecting shaft, is provided with the second elastic structure between described transmission shaft and described projecting shaft.
As preferably, described projecting shaft front end offers passage, and described transmission shaft rear end is stretched in described passage, and is acted in described passage by described second elastic structure and move reciprocatingly.
As preferably, the elasticity coefficient of described second elastic structure is greater than the elasticity coefficient of described first elastic structure.
As preferably, described transmission shaft front end is provided with draw-in groove and coordinates described driven shaft.
As preferably, described projecting shaft front end is provided with outer rib and limits described second elastic structure.
As preferably, described supporting foot is provided with hole clipping groove and holds described projecting shaft.
In sum, the utility model achieves supporting foot in dunnage, has an elastic component automatic spring engaging supporting foot when rising to certain altitude, then only need press the button when needs close, projecting shaft will rebound, whole process operation is convenient, safety coefficient is high, and structure stability is strong.Passage, draw-in groove, the setting of outer rib can ensure whole closure structure on the same axis, ensures the fluency of motion.The elasticity coefficient that the elasticity coefficient of the second elastic structure is greater than described first elastic structure can ensure that the appliance for releasing single of projecting shaft out engages supporting foot.
Accompanying drawing explanation
Fig. 1 is side view cutaway drawing of the present utility model;
Fig. 2 is fastener intrinsic single schematic diagram of the present utility model;
In Fig. 1 and Fig. 2,1-fastener body, 2-dunnage, 3-supporting foot, 4-projecting shaft, 5-first elastic structure, 6-driven shaft, 7-coupling shaft, 8-button, 9-transmission shaft, 10-second elastic structure, 11-outer cover body, 31-hole clipping groove, 41-passage, 42-outer rib, 91-draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The self-closing fastener of one as depicted in figs. 1 and 2, comprises fastener body 1 and the dunnage 2 arranging fastener body 1, dunnage 2 is provided with the supporting foot 3 coordinating fastener body 1.Fastener body 1 is provided with outer cover body 11, outer cover body 11 is as a whole with dunnage 2; Be equipped with driven shaft 6 in outer cover body 11, driven shaft 6 front end is connected with coupling shaft 7, and coupling shaft 7 front end is fixedly connected with button 8; Driven shaft 6 rear end is connected with transmission shaft 9, and transmission shaft 9 rear end is provided with projecting shaft 4, is provided with the second elastic structure 10 between transmission shaft 9 and projecting shaft 4, projecting shaft 4 is provided with the first elastic structure 5 and coordinates with dunnage 2 and regulate projecting shaft 4 and supporting foot 3 tap.
Projecting shaft 4 front end offers passage 41, and transmission shaft 9 rear end is stretched in passage 41, and is acted in passage 41 by the second elastic structure 10 and move reciprocatingly.Transmission shaft 9 front end is provided with draw-in groove 91 and coordinates driven shaft 6.Projecting shaft 4 front end is provided with outer rib 42 and limits the second elastic structure 10.Supporting foot 3 is provided with hole clipping groove 31 and holds projecting shaft 4.
The elasticity coefficient of the second elastic structure 10 is greater than the elasticity coefficient of the first elastic structure 10.Because when supporting foot 3 is packed up, the active force of the first elastic structure 5 is greater than the active force of the second elastic structure 10; When supporting foot 3 rises, the first elastic structure 5 promotes the second elastic structure 10 and projecting shaft 4 moves backward, makes hole clipping groove 31 hold projecting shaft 4.Press the button 8, driven shaft 6 travels forward a segment distance, the first elastic structure 5 is stretched naturally, and then under the effect of the second elastic structure 10, projecting shaft 4 is away from supporting foot 3, and supporting foot 3 is recovered in dunnage 2.When supporting foot 3 is recovered in dunnage 2, press the button 8, make the first elastic structure 5 be in stress, time following supporting foot 3 is stretched out, projecting shaft 4 can eject automatically.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification, as long as but be all subject to the protection of Patent Law in right of the present utility model.
