Abstract

The utility model relates to an emergency-stop locking push button, which comprises a push button, a locking rod, microswitches and a lock body; wherein, the locking rod is coaxially assembled on a push button pad fixed on a door body; the lock body is fixed on the inner side of the push button pad; the microswitches are assembled on the lower end of the lock body; a jackscrew is assembled at a radial position on the lock body, which corresponds to the axial line of the locking rod; a cylindrical spring is coaxially assembled on the front end of the jackscrew; a steel ball is coaxially assembled on the front end of the cylindrical spring; on the locking rod, an upper spacing groove and a lower spacing groove are respectively arranged at the position of the steel ball in the lock body; on the locking rod, a conical lug boss is arranged at the positions of the contacts of the microswitches; a support is fixed on the push button pad on the lateral side of the button; a retaining plate which is clamped in an annular groove formed on the radial periphery of the button is hinged in the support; and the lower end of the support is provided with a locking hole which can lock the retaining plate after the retaining plate is positioned. The utility model resolves the phenomenon of production interruption caused by misoperation and can timely and effectively handle emergency in production, thus ensuring uninterrupted production.

Description

A kind of urgency lock button of closing down

Technical field

The utility model relates to the mine flameproof and intrinsic safety type unit switch, especially a kind of urgency lock button of closing down.

Background technology

In process of production, the production equipment on the production line will move for a long time by the operation of setting, and the equipment on the production line is more usually, and is provided with to such an extent that relatively disperse, and therefore occurs because the phenomenon that the caused production of misoperation is interrupted through regular meeting.Gather in the production process in present colliery, usually adopting the Flameproof intrinsically safe unit switch that fully-mechanized mining working and belt transportation five equilibrium are casually arranged with fully controls, owing on the existing unit switch special locking device is not set, therefore the effectively accident in the process for producing, guarantee carrying out continuously of production, reduced the security reliability of producing.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, reliability is high and can guarantee urgency that production line carries out the continuously lock button of closing down.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of urgency lock button of closing down, by button, deadlock lever, sensitive switch, lock body constitutes, the coaxial end that is installed in deadlock lever of button, deadlock lever is axial displacement in lock body, it is characterized in that: deadlock lever is coaxial to be installed on the push button pad that is packed on the body, install lock body in the push button pad inboard, the bottom of this lock body is equipped with sensitive switch, lock body radial position at corresponding deadlock lever axis is equipped with a jackscrew, front end at jackscrew is coaxially installed with a cylindrical spring, the front end of this cylindrical spring is coaxially installed with a steel ball, the steel ball position of deadlock lever in lock body is shaped on respectively, following two stopper slots, deadlock lever is shaped on a conical boss at the sensitive switch contact position, on the push button pad of button side, be fixed with a support, hinge is adorned a catch that is installed in the formed annular groove of button radially outer edge in this support, and the lower end of support is shaped on one can be at the lockhole of catch location back locking catch.

And, be coaxially installed with a copper sheathing between described deadlock lever and the push button pad.

Advantage of the present utility model and beneficial effect are:

1. the close down deadlock lever of lock button of this urgency adopts axial displacement secondary limit method, spacing reliable and scalable, and latch performance is good, and is simple in structure, is convenient to operation.

This urgency close down the lock button push button pad on a support is installed, hinge is adorned a catch in this support, one end of this catch is installed in the made annular stop groove of button, when pressing latch buttons, catch rotates thereupon, and the made lockhole in support lower end is exposed, this moment, available tapered end pinned lockhole, therefore guarantee that this operating state can not at will change, must under artificial released state, could change operating state, reach the purpose of safety in production with this.

3. this urgency lock button of closing down adopts the upper and lower motion of the conical boss of deadlock lever, realize the open and close of latch switch by the mode of touching sensitive switch, and a support that is shaped on lockhole on it is installed in push button pad, realize double locking, design science is reasonable, has solved because the phenomenon that the caused production of misoperation is interrupted, the accident in can timely and effective process for producing, guarantee carrying out continuously of production, avoided the generation of production accident.

Fig. 1 is front view of the present utility model (broken section);

Fig. 2 is that the A-A of Fig. 1 is to cutaway view (released state);

Fig. 3 is that the A-A of Fig. 1 is to cutaway view (blocking).

Embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.

A kind of urgency lock button of closing down, be installed on the body 14, on the door body, install a push button pad 4 by welding manner, medium position at this push button pad is coaxially installed with a deadlock lever 16, be coaxially installed with a copper sheathing 15 between this deadlock lever and the push button pad, be coaxially installed with a button 3 in the deadlock lever end in the push button pad outside; Be fixed with a lock body 13 in the push button pad inboard by screw 5, the bottom of this lock body is equipped with sensitive switch 6, and the quantity of this sensitive switch can be set according to actual needs.Lock body radial position at corresponding deadlock lever axis is equipped with a jackscrew 12, is coaxially installed with a cylindrical spring 11 at the front end of jackscrew, and the front end of this cylindrical spring is equipped with a steel ball 10.The steel ball position of deadlock lever in lock body is shaped on upper and lower two stopper slots 8 respectively, and these two stopper slots up and down can be undertaken spacing by steel ball respectively during axial displacement at deadlock lever; Deadlock lever is shaped on a conical boss 9 in the sensitive switch position that lock body is installed, and this conical boss can touch the contact 7 of sensitive switch in the upper and lower displacement process, realizes the open and close of sensitive switch.

On the push button pad of button side, be fixed with a support 1, adorn a catch 2 by hinge 18 hinges in this support, the end that this catch stretches out support is installed in the formed annular groove 17 of button radially outer edge, and the lower end of support is shaped on one can be at the lockhole 19 of catch location back locking catch.

Operation principle of the present utility model is:

When button was in as shown in Figure 2 position, steel ball was spacing in the enable possition (being the lower limit site) with deadlock lever, and conical boss can not be opened sensitive switch; This moment, lockhole was covered in by catch, can not lock.

As shown in Figure 3, press the button, steel ball is spacing, and meanwhile, conical boss touches the contact of sensitive switch and starts sensitive switch locked position of coupler (being upper limit site), realizes locking; At this moment, along with the displacement of button, catch rotates, and lockhole is exposed, and available tapered end pins lockhole, so that make the latch buttons location.Guarantee that this operating state can not at will change, must under artificial released state, could change operating state, reach the purpose of safety in production with this.
