Utility model content
The utility model aims to provide the simple and safe and reliable anti-self-locking switch mechanism of a kind of structure.
For achieving the above object, the utility model provides following technical scheme: anti-self-locking switch mechanism, comprise casing, switch, shift knob, Compress Spring, A rotating shaft, switch trigger, trigger boss, swivel mount, B rotating shaft, switch pushing block, pushing block boss and extension spring, the handbar of casing is located at by described switch, switch is provided with shift knob, switch is connected with switch trigger by Compress Spring, and described switch trigger is fixed on casing by A rotating shaft; Described switch Bearing Angle is provided with trigger boss, is provided with swivel mount above switch trigger, and swivel mount is fixed on casing by B rotating shaft; Described swivel mount is provided with extension spring, and its position is above B rotating shaft, and one end of extension spring connects swivel mount, and the other end connects casing, and described swivel mount top is provided with switch pushing block, and switch pushing block is provided with pushing block boss.
As further scheme of the present utility model: described A rotating shaft is arranged on switch spanner motor spindle.
As further scheme of the present utility model: described B rotating shaft is arranged on swivel mount middle part.
As further scheme of the present utility model: be provided with the hook matched with trigger boss bottom described swivel mount.
As further scheme of the present utility model: described pushing block boss contacts with swivel mount.
Compared with prior art, the beneficial effects of the utility model are: this anti-self-locking switch mechanism, the unblock of switch trigger is realized by pull switch trigger, and Compress Spring makes switch trigger reset after switch closedown, extension spring makes swivel mount reset, locking switch trigger, thus the anti-self locking function realizing switch; The utility model structure is simple, and self-locking is reliable, can meet new mechanical order requirement, be worth promoting.
Accompanying drawing explanation
Overall schematic of the present utility model when Fig. 1 is switch trigger lock;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Overall schematic of the present utility model when Fig. 3 is the unblock of switch trigger;
Fig. 4 is the A place enlarged drawing of Fig. 3.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-3, in the utility model embodiment, anti-self-locking switch mechanism, comprise casing 1, switch 2, shift knob 3, Compress Spring 4, A rotating shaft 5, switch trigger 6, trigger boss 7, swivel mount 8, B rotating shaft 9, switch pushing block 10, pushing block boss 11, extension spring 12 and hook 13, the handbar of casing 1 is located at by described switch 2, switch 2 is provided with shift knob 3, switch 2 is connected with switch trigger 6 by Compress Spring 4, described switch trigger 6 is fixed on casing 1 by A rotating shaft 5, A rotating shaft 5 is arranged on bottom switch trigger 6, switch trigger 6 can rotate around A rotating shaft 5, described switch trigger 6 top is provided with trigger boss 7, is provided with swivel mount 8 above switch trigger 6, and swivel mount 8 is fixed on casing 1 by B rotating shaft 9, and B rotating shaft 9 is arranged on swivel mount 8 middle part, and swivel mount 8 rotates by B rotating shaft 9, the hook 13 matched with trigger boss 7 is provided with bottom described swivel mount 8, described swivel mount 8 is provided with extension spring 12, and its position is above B rotating shaft 9, and one end of extension spring 12 connects swivel mount 8, the other end connects casing 1, described swivel mount 8 top is provided with switch pushing block 10, and switch pushing block 10 is provided with pushing block boss 11, and pushing block boss 11 contacts with swivel mount 8.
Operation principle of the present utility model: when not using machine, swivel mount 8 strained by extension spring 12, makes the hook 13 on swivel mount 8 fasten trigger boss 7.Now namely use finger buckle to live switch trigger 6, switch trigger 6 also cannot be pressed down, and shift knob 3 also just can not be pressed, and circuit is in off-state, and motor cannot start.When starting the machine, with thumb by switch pushing block 10 driven forward, pushing block boss 11 promotes swivel mount 8, makes swivel mount 8 rotate clockwise certain angle around the shaft, and the hook 13 on swivel mount 8 departs from the boss of switch trigger 6.Fasten switch trigger 6 with all the other four fingers closed up, switch trigger 6 is pressed down, and shift knob 3 is also just pressed, and circuit is in on-state, machine startup.During closing machine, unclamped by the finger pressing switch trigger 6, under the elastic force effect of Compress Spring 4, switch trigger 6 rotates clockwise, and resets; Swivel mount 8 rotates counterclockwise around the shaft under extension spring 12 acts on, and move after switch pushing block 10, the hook 13 on swivel mount 8 fastens trigger boss 7, and switch trigger 6 is lockable.
