Summary of the invention
Problem to be solved in the utility model is, overcome the deficiencies in the prior art, a kind of straight side press safety device is provided, the telescopic arm that adopts adjustable-height and hold out against mould Lift up and down is safety post fixedly, has avoided movement or sideways problem because of the external force generation, the use of telescopic arm, be convenient to picking and placeing of safety post, also increased the control to circuit simultaneously, avoided the mould that causes because of the false touch switch closed dangerous, circuit and mechanical hazard hidden danger have been taken precautions against simultaneously.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of straight side press safety device that provides according to the utility model, comprise safety post, telescopic arm, hook and touch switch, described telescopic arm holder is installed on the lathe, the telescopic arm holder is connected with pivot pin two by pivot pin one with telescopic arm, the safety post holder is connected on the telescopic arm, the safety post screw is assemblied on the safety post with the protection screw, safety post after the assembling is put into the safety post holder, the holder screw is locked and is aimed in the chute of safety post, hook holder and touch switch are installed on the lathe respectively, one end coupling hook holder of hook, the other end of hook connect or break away from telescopic arm.
The utility model compared with prior art has significant advantage and beneficial effect:
1. the safety post height dimension of prior art is fixed, can leave the space when being placed between the mould of unlatching, can produce acceleration shock power during the crank block accidental, safety post of the present utility model adopts adjustable-height and holds out against mould Lift up and down, the acceleration shock power that produces when avoiding the crank block accidental.
2. the safety post of prior art can produce mobile or sideways when being subjected to external force, lose the security protection effect, the utility model has increased fixedly safety post of telescopic arm, holds out against the mould Lift simultaneously, has avoided the movement or the sideways problem that produce because of external force.Picking and placeing of safety post is convenient in the use of telescopic arm simultaneously.
3. increased the control to circuit, avoided the mould that causes because of the false touch switch closed dangerous, circuit and mechanical hazard hidden danger have been taken precautions against simultaneously.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
