Description
Technical field
Emergency stop switch technical field is the utility model is related to, more specifically, it relates to a kind of emergency stop switch protective device.
Background technology
Emergency stop switch is both provided with mechanical equipment.Emergency stop switch is used to, when the state of emergency or accident occurs, press i.e.
Can arrestment immediately operation.Prevent the more serious state of affairs.Emergency stop switch, which is generally provided on control panel, to be compared
Obvious position.Also just because of this reason, staff is when carrying out panel operation, sometimes because notice not enough collects
In and mistake presses emergency stop switch, cause equipment to be shut down without rhyme or reason in the case where fault-free and accident occur.It is continuous for some
For the equipment of operation, shut down once, that is, need to carry out waste discharge and restart operation.This had both wasted substantial amounts of raw material, increased
Cost is added, has more importantly been that after shutting down production efficiency can be caused low, has severely impacted production, also increased work people
The labor intensity of member.
Utility model content
Generally it is provided on control panel for existing emergency stop switch easy to be more wrong by employee than more prominent position
The technical problem pressed, the utility model provide a kind of emergency stop switch protective device, it, which has, avoids maloperation, convenient and practical excellent
Point.
To achieve the above object, the utility model provides following technical solution：

Fluid passing power.
Further, the return unit is elastic component, its one end away from the pressing piece is fixedly connected on the protection
On cover.
Through the above technical solutions, elastic component tensioner is between pressing piece and protective cover, so that pressing piece keeps protrusion
Non-pressed state.
Further, the return unit is arranged on one end of the pressing piece insertion crimping box, the return unit
Density be less than the non-newtonian fluid.
Through the above technical solutions, return unit is floated on non-newtonian fluid, so as to provide expanding force to pressing piece, make pressing
Part keeps the non-pressed state of protrusion.
Further, it is fixedly connected with flexible supporting item between the crimping box and the control panel.
Through the above technical solutions, supporting item provides support force to crimping box, the weight of crimping box and non-newtonian fluid is avoided
Power has an impact emergency stop switch, improves the antijamming capability of protective device.
Further, the protective cover abuts to be fixedly connected on the periphery of the control panel and is useful for adsorbing the control
The adsorption piece of panel.
Through the above technical solutions, adsorption piece adsorbs protective cover on the control panel so that the position of protective cover can be consolidated
It is fixed.
Further, the adsorption piece is arranged to flared, it is flared towards the control panel, the adsorption piece it is interior
It is fixedly connected with soft gluing capsule on wall, it is described gluing intracapsular to be filled with glue.
Through the above technical solutions, glue can will fill up the gap between adsorption piece and control panel, adsorption piece is improved
Adsorption strength, make protective cover regularly more stable.
Further, the adsorption piece is magnetic part, and the control panel is made of permeability magnetic material.
Through the above technical solutions, adsorption piece by magnetic-adsorption on the control panel, it is easy to assemble, go out when emergency stop switch therefore
After barrier, protective device can be dismantled and recycled, economized on resources.
Compared with prior art, the beneficial effects of the utility model are：By, covered with protective cover, preventing outside emergency stop switch
Pressing piece is plugged with shield, be provided between pressing piece and emergency stop switch include non-newtonian fluid to crimp box dynamic to transmit
Power, when equipment, which breaks down, needs emergency stop, employee takes firmly and rapidly pressing piece, on the depressed part of non-newtonian fluid
Shearing force speed so as to increasing the viscosity of its own, the then passing power between pressing piece and emergency stop switch；When setting
It is standby that the shearing force speed of pressing piece is slower, and the viscosity of non-newtonian fluid is small when emergency stop is not required, can not passing power so that nothing
Method makes emergency stop switch be pressed, the emergency stop switch of protection, convenient and practical.
