Summary of the invention:
It is high that the purpose of this utility model is to provide a kind of security performance, do not shut Shi Buhui at protective glasses and start and guarantee personal safety, avoid damaging the protective glasses safety switch construction of the automatic sewing machine of the machine of threading.
The utility model is achieved in that
A kind of protective glasses safety switch construction of automatic sewing machine, include nose shell and be hinged on protective glasses on nose shell, the safety switch that machine does not start after being provided with protective glasses and nose shell separates on a madial wall of protective glasses, safety switch is connected with controller.
Above-mentioned safety switch is installed in by the safety switch case on the madial wall of protective glasses, and the trigger point of safety switch is connected with the nose shell contact.
Above-mentioned safety switch case is that left surface and bottom surface are the housing of opening, be provided with safety switch cable-through hole or crossed beam trunking on the upper plane of housing, be provided with erection column on the inwall on the plane, right side of housing, be provided with at the outer surface of housing the mount pad that is connected with protective glasses.
Be provided with to regulate the bar-shaped trough of safety switch position on above-mentioned mount pad.
Being provided with on above-mentioned safety switch can be for the installation through hole of the insertion of the erection column on the safety switch case, and the trigger point of safety switch is towards the nose shell setting.
Above-mentioned safety switch is touch switch.
The advantage that the utility model is given prominence to compared to existing technology is:
When 1, protective glasses of the present utility model is shut, sending signal after the contact of safety switch on protective glasses and nose shell is connected can start, nose shell do not detected and can not start yet even contact with nose shell at safety switch, greatly improved safety by property, guarantee workman's personal safety, avoid causing due to workman's misoperation the damage of Sewing machines;
2, the utility model is simple in structure, and is easy for installation;
3, the utility model is applicable on the Sewing machines of various automatic seams, automatic shearing type.
Description of drawings:
Fig. 1 is that the utility model is arranged on the schematic diagram on casing;
Fig. 2 is that safety switch of the present utility model is arranged on the schematic diagram on protective glasses;
Fig. 3 is that safety switch of the present utility model is arranged on the schematic diagram in the safety switch case;
Fig. 4 is the schematic diagram of safety switch case of the present utility model;

The specific embodiment:
The below is further described the utility model with specific embodiment, referring to Fig. 1-5:
A kind of protective glasses safety switch construction of automatic sewing machine, include nose shell 10, and the protective glasses 20 on nose shell 10 of being articulated and connected, being provided with the safety switch 30 that does not start with machine after nose shell 10 separates on a madial wall of protective glasses 20, safety switch 30 is connected with controller.
Above-mentioned safety switch 30 is installed in by safety switch case 40 on the madial wall of protective glasses 20, and the trigger point 301 of safety switch 30 is connected with nose shell 10 contacts.
Above-mentioned safety switch case 40 is that left surface and bottom surface are the housing of opening, be provided with safety switch cable-through hole or crossed beam trunking 402 on the upper plane 401 of housing, be provided with erection column 404 on the inwall 403 on the plane, right side of housing, be provided with at the outer surface of housing the mount pad 405 that is connected with protective glasses.
Be provided with to regulate the bar-shaped trough 406 that safety open off-position 30 is put on above-mentioned mount pad 405.
Be provided with the installation through hole 302 that can insert for the erection column 404 on safety switch case 40 on above-mentioned safety switch 30, the trigger point 301 of safety switch 30 arranges towards nose shell 10.
Above-mentioned safety switch 30 is touch switch.
Operation principle of the present utility model:
When protective glasses 20 was raised, safety switch 30 sent a signal to controller, and this moment, machine was in not starting state; When protective glasses 20 was closed, the trigger point 301 of safety switch 30 was triggered by nose shell 10, and at this moment, safety switch 30 sends a signal to controller, but machine is in starting state.
