Abstract
A kind of self-closing safety door, it include: door leaf, the universal caster wheel that door leaf lower part is set, the door-hinge that door leaf side is set, the limit door shield that the door leaf other side is set, wherein, the bottom of universal caster wheel is supported on arc slope board, and arc slope board is fixed on vertically on fixed pillar；Door-hinge is sleeved on vertically in fixed pillar, and can be moved freely above and below along fixed pillar.The utility model is only needed by self gravity, by door lower part castor freely rolling along cambered surface slope, just can guiding door after personnel's discrepancy, realize and flexibly voluntarily close, solve the problems, such as the mechanical breakdowns such as Caton, fatigue failure meaning, accidental falling.
Description
Technical field
The utility model relates to safety door more particularly to a kind of self-closing safety for all kinds of modularization steel structure platforms
Door.Belong to petrochemical industry.
Background technique
Currently, general industry security door is setting in opening, ladder mouth, stair passway, roof hatch and all
The customary passway for needing to be serviced the restricted area of maintenance, it is fixed in platform astasia for protecting operator
In the case of, retreat the protective equipment of tumble.
Existing industry security door when in use, needs manual operation chain, bolt or slip pipe with closed safe door, due to
Do not have function of self closing, there are some potential safety problemss.
To solve the above-mentioned problems, it generallys use door-hinge eccentric center principle or spring structure realizes function of self closing, it is still, above-mentioned
Method is easy that personnel is made to feel laborious or be easy to appear the mechanical breakdowns such as Caton, fatigue failure meaning, accidental falling.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide a kind of self-closing peace
Air cock is only needed by self gravity, by door lower part castor freely rolling along cambered surface slope, just can guiding door in people
After member enters and leaves, realization is flexibly voluntarily closed, and solves the problems, such as the mechanical breakdowns such as Caton, fatigue failure meaning, accidental falling.
The purpose of this utility model is realized by the following technical solutions:
A kind of self-closing safety door, it is characterised in that: include: door leaf, the universal caster wheel that door leaf lower part is set, setting exist
The door-hinge of door leaf side, the limit door shield that the door leaf other side is set, wherein the bottom of universal caster wheel is supported on arc slope board
On, arc slope board is fixed on vertically on fixed pillar；Door-hinge is sleeved on vertically in fixed pillar, and can be along fixed pillar
It moves freely above and below.
The limit door shield is plate, and is mounted in the middle part of door leaf side.
The utility model has the beneficial effects that the utility model is due to the adoption of the above technical scheme, it is easy for installation, it is only necessary to
By self gravity, by door lower part castor freely rolling along cambered surface slope, just can guiding door personnel enter and leave after, realize
It flexibly voluntarily closes, solves the problems, such as the mechanical breakdowns such as Caton, fatigue failure meaning, accidental falling.
