Detailed description of the invention
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In embodiment one as shown in Figure 1 and Figure 2, self-locked draught part comprises pull head body 1, pulling block 2, horse hook 21, pulling-on piece 3, block 4, reseting shrapnel 5, block shell fragment 6.Pull head body 1 comprises upper plate 11, lower plate 12 and guide pillar 13.Upper plate 11 is provided with through hole 111 and projection 112.Pulling block 2 and projection 112 are by projection axis hole 1122 and pulling block axis hole 22 and sell hinged, and pulling block 2 can be rotated along jointed shaft.Pulling block 2 also establishes horse hook 21, and horse hook 21 runs through upper plate 11 by through hole 111, stretches out the lower surface of upper plate 11.The surfaces of revolution that projection 112 is relative with pulling block 2 is provided with two relative shrinkage pools, and reseting shrapnel 5 is interspersed in described two shrinkage pools.
Corner cut 23 is also provided with near one end of described jointed shaft at pulling block 2.And on projection 112, the position fitted with the corner cut 23 of pulling block 2 is also provided with the pit 1123 corresponding with corner cut 23.The Main Function of pit 1123 is that the thickness of coating on the position corresponding to corner cut affects the result of use of pulling block in order to prevent projection when spraying paint plating.
Pulling block 2 is provided with opening 26.Block 4 is hinged with the axis hole 24 of pulling block one end by block axis hole 44 with pulling block 2.Block shell fragment 6 to be placed under block 4 and to insert pulling block 2.Pulling block 2 other end is provided with backstop 25, blocks one end 45 of block 4, can only rotate with limit stop 4 in opening 26.The draw ring 36 of pulling-on piece 3 is removably placed in opening 26.
When pulling-on piece 3 pulls pulling block 2 by draw ring 36, pulling block 2 rotates along the jointed shaft hinged with projection 112, and horse hook 21 is mentioned, and slide fastener can pull; Reseting shrapnel 5 is out of shape simultaneously, produces reseting elasticity.Pulling block 2, by the restriction of corner cut 23, can only turn to the degree that horse hook 21 does not depart from the upper surface of upper plate 11 completely, the corner cut 23 i.e. upper surface of contact upper plate 11, thus makes horse hook 21 action when resetting more reliable.
Put down pulling-on piece 3, pulling block 2 is due to the reseting elasticity of reseting shrapnel 5, and drive horse hook 21 to rotate backward, get back to initial position, horse hook 21 runs through upper plate 11 by through hole 111, and stretches out the lower surface of upper plate 11, thus pins slide fastener, achieves the self-locking of slide fastener.
When pulling-on piece 3 changed by needs, pressure block 4, block 4 rotates along the jointed shaft hinged with pulling block 2, and the opening 26 of pulling block 2 is open, to change pulling-on piece 3; Simultaneously block shell fragment 6 is depressed distortion, generation screen resilience.After pulling-on piece 3 is changed, decontrol block 4, block 4 rebounds by the screen resilience effect of block shell fragment 6, and is blocked one end 45 of block 4 by backstop 25, makes the opening 26 of pulling block 2 completely closed.Thus pulling-on piece 3 is changed easily.
In embodiment two as shown in Figure 3, Figure 4, self-locked draught part comprises pull head body 1, pulling block 2, horse hook 21, pulling-on piece 3, back-moving spring 7, resilient pin 8.The upper plate 11 of pull head body 1 is provided with through hole 111 and projection 112.Pulling block 2 is hinged with projection 112, and pulling block 2 can be rotated along jointed shaft.Pulling block 2 also establishes horse hook 21, and horse hook 21 runs through upper plate 11 by through hole 111, stretches out the lower surface of upper plate 11.Pulling block arranges groove 27, accommodating back-moving spring 7 in groove 27; Back-moving spring 7 one end connects pulling block 2, and the other end connects upper plate 11.
On one end end face of one end of described jointed shaft, projection 28 is provided with at pulling block 2.
Pulling block 2 is provided with opening 26.A groove is respectively established at opening two ends, and night bolt 8 is positioned in two grooves.
When pulling-on piece 3 pulls pulling block 2 by draw ring 36, pulling block 2 rotates along the jointed shaft hinged in projection 112, and horse hook 21 is mentioned, and slide fastener can pull; Back-moving spring 7 elongates simultaneously, produces reseting elasticity.Pulling block 2, by the restriction of projection 28, can only turn to the degree that horse hook 21 does not depart from the upper surface of upper plate 11 completely, the projection 28 i.e. upper surface of contact upper plate 11, thus make the homing action of horse hook 21 more reliable.
Decontrol pulling-on piece 3, pulling block 2 is due to the reseting elasticity of back-moving spring 7, and drive horse hook 21 to rotate backward, get back to initial position, horse hook 21 runs through upper plate 11 by through hole 111, and stretches out the lower surface of upper plate 11, thus pins slide fastener, achieves the self-locking of slide fastener.
When pulling-on piece 3 changed by needs, Compress Spring latch 8 also takes out, and opening 26 is open, to change pulling-on piece 3.After pulling-on piece 3 is changed, Compress Spring latch 8 is also inserted in the groove at opening 26 two ends, make opening 26 completely closed, thus pulling-on piece 3 is changed easily.
Description above describe the preferred embodiments of the present invention, but be to be understood that the present invention is not limited to above-described embodiment, and should not regard the eliminating to other embodiments as.By enlightenment of the present invention, the change that those skilled in the art carry out in conjunction with known or prior art, knowledge also should be considered as in protection scope of the present invention.
