Description
Technical field
The utility model relates to a kind of suspender switch circuit controller of controlling the suspender opening and closing movement.
Background technology
In the suspender use, before lifting, require suspender to keep open state, so that material can get in the opening of suspender smoothly, when needs lift by cranes, make the suspender can be closed again, to clamp material, so just need a kind of suspender switch circuit controller.The existing employed switch circuit controller of suspender mainly contains two kinds; A kind of is to be representative with Chinese patent ZL200520070269.3; The weak point of this suspender switch circuit controller is: 1, three waveform spigot surfaces are arranged; Comprise two waveform master spigot surfaces and an auxiliary spigot surface, complex structure, difficulty of processing is big; 2, in the on-off action process, the friction position of parts is many, causes fault rate higher.Another kind is to be representative with Chinese patent ZL 200810228123.5; The weak point of this suspender switch circuit controller is: 1, will use this switch circuit controller, the fixedly fixed link 9 and hook 10 of switch circuit controller need be set on suspender, these parts are by the structure complicated of suspender; 2, switch circuit controller and attached parts thereof can not be symmetrically distributed with the axis of suspender; When mentioning suspender, can make suspender produce deflection like this, be unfavorable for workman's operation.
Summary of the invention
The utility model purpose is in order to solve the above-mentioned technical matters that prior art exists.
The utility model has designed a kind of sliding type suspender switch circuit controller; Technical scheme is: its structure comprises sliding sleeve 1, plug 2, spring 3, automatic pinning 4, guide rod 5, tapered sleeve 6, and sliding sleeve 1 bilateral symmetry is provided with spring perch 1-1, and guide rod 5 is provided with support ring 5-1 and projection 5-2; Tapered sleeve 6 is provided with transition rings 6-1; The complete interlock of upper surface of the lower surface of guide rod supports ring 5-1 and tapered sleeve transition rings 6-1, sliding sleeve 1, tapered sleeve 6 all are enclosed within on the guide rod 5, and guide rod 5 can be free to slide in sliding sleeve 1 with tapered sleeve 6; Spring 3 is located among the spring perch 1-1 with automatic pinning 4, and plug 2 is captiveed joint with spring perch 1-1.
Described spring perch 1-1, plug 2, spring 3, automatic pinning 4 all are symmetrically arranged with two.
This switch circuit controller relies on the switching of accomplishing switch circuit controller that slides up and down of guide rod 5 and tapered sleeve 6.When initial position, be suspended on the automatic pinning 4 at guide rod supports ring 5-1, this moment, suspender relied on switch circuit controller to keep open state; When needs clamp material, let guide rod 5 upward movements, because the position-limiting action of projection 5-2; Tapered sleeve 6 is also along with guide rod 5 upward movements, when the transition rings 6-1 of tapered sleeve 6 with after automatic pinning 4 contacts, the transition rings 6-1 of tapered sleeve 6 is two automatic pinning 4 spreadings; Because the pressuring action of spring 3, the transition rings 6-1 of tapered sleeve 6 finally hangs on the automatic pinning 4, at this moment lets guide rod 5 move downward; When the support ring 5-1 of guide rod 5 contacted with tapered sleeve, automatic pinning 4 was again by spreading, because the lower surface of guide rod supports ring 5-1 and the upper surface perfect fitting of tapered sleeve transition rings 6-1; So automatic pinning 4 can slide into the top of guide rod supports ring 5-1 along the periphery of support ring 5-1 and transition rings 6-1; This moment, the support ring 5-1 and the automatic pinning 4 of guide rod were thrown off, and suspender can be free closed, thereby pick up material.
Adopt the suspender switch circuit controller of this technical scheme, structurally saved the waveform spigot surface, make designs simplification, and the difficulty of processing also reduces a lot; Utilize the mode of automatic pinning 4 suspension guide rod supports ring 5-1, safe and reliable, guaranteed suspender safety in use.The utility model has continued the advantage of Chinese patent ZL200520070269.3 in addition, can be installed on the axis of suspender, and when using suspender, suspender is not easy to take place deflection, is convenient to workman's operation.But this switch circuit controller can not bear too big gravity, so than being more suitable for small-sized suspender.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Sliding type suspender switch circuit controller comprises: sliding sleeve 1, plug 2, spring 3, automatic pinning 4, guide rod 5, tapered sleeve 6; Sleeve 1 bilateral symmetry is provided with spring perch 1-1; Guide rod 5 is provided with support ring 5-1 and projection 5-2, and tapered sleeve 6 is provided with transition rings 6-1, the complete interlock of upper surface of the lower surface of guide rod supports ring 5-1 and tapered sleeve transition rings 6-1; Sliding sleeve 1, tapered sleeve 6 all are enclosed within on the guide rod 5; Guide rod 5 can be free to slide in sliding sleeve 1 with tapered sleeve 6, and spring 3 is located in the spring perch with automatic pinning 4, and plug 2 is connected with spring perch 1-1.This switch circuit controller relies on the switching of accomplishing switch circuit controller that slides up and down of guide rod 5 and tapered sleeve 6.When on suspender, using this switch circuit controller, sliding sleeve 1 is arranged on the lifting plate 7, and guide rod 5 is connected with supporting plate 8.
When initial position, be suspended on the automatic pinning 4 at guide rod supports ring 5-1, make the vertical fixed distance of lifting plate 7 and supporting plate 8 like this, this moment, suspender relied on switch circuit controller to keep open state.Like Fig. 1,9.
When needs clamp material, let guide rod 5 upward movements, because the position-limiting action of projection 5-2, tapered sleeve 6 is also along with guide rod 5 upward movements, when the transition rings 6-1 of tapered sleeve 6 contacts with automatic pinning 4, the transition rings 6-1 of tapered sleeve 6 is two automatic pinning 4 spreadings.Like Fig. 5.
Because the pressuring action of spring 3, the transition rings 6-1 of tapered sleeve 6 finally hangs on the automatic pinning 4.Like Fig. 6.
At this moment let guide rod 5 move downward, the support ring 5-1 of guide rod 5 contacts with tapered sleeve fully.Like Fig. 7.
Then; Automatic pinning 4 is again by spreading, because the lower surface of guide rod supports ring 5-1 and the complete interlock of upper surface of tapered sleeve transition rings 6-1, so automatic pinning 4 can slide into the top of guide rod supports ring 5-1 along the periphery of support ring 5-1 and transition rings 6-1; This moment, the support ring 5-1 and the automatic pinning 4 of guide rod were thrown off; This moment, lifting plate 7 can freely change with the vertical distance of supporting plate 8, and suspender can be free closed, thereby pick up material.Like Fig. 8,10.
When needs let suspender recover open state, repeat above-mentioned motion process, guide rod supports ring 5-1 is suspended on the automatic pinning 4 will move to the said state of Fig. 6 by state shown in Figure 7 again.
