Abstract

The utility model discloses an anti-opening system for a fire exit door. The anti-opening system for the fire exit door comprises a fire exit door, wherein the fire exit door comprises two door planks which are opened oppositely. The anti-opening system for a fire exit door is characterized in that the two door planks are locked through a disposable fragile locking ring. The disposable fragile locking ring is set with a non-repetitive serial number. According to the anti-opening system for the fire exit door, the common disposable fragile locking ring is adopted to lock the fire exit door. The locking ring is set with an only serial number, and therefore a person can know about whether the fire exit door is opened so long as the person checks whether the locking ring is damaged and the serial number is changed during daily inspections. Who opens the fire exit door and when the fire exit door is opened can be checked and known so long as corresponding surveillance videos are matched. The anti-opening system for the fire exit door is low in cost and good in effect.

Description

Fire exit door is prevented open system

Technical field

The utility model relates to a kind of fire exit door protective device, needs normally closed fire exit door in particular for occasions such as pharmaceutical factories.

Background technology

Fire exit door is the necessary facility of each heavy construction.And the mechanisms such as pharmaceutical factory, hospital are very high to the air purity requirement, wish that therefore the fire exit door that is arranged between contaminated area and the clean area is normally closed, and people's turnover can only be by the clean passage of special use.And fire exit door can not use lockset that it is locked, how to stop some people and schemes conveniently to take a short cut, and be present problem demanding prompt solution by the fire exit door turnover arbitrarily.

Summary of the invention

The utility model provides a kind of solution of the above problems, provides low, the effective fire exit door of a kind of cost to prevent open system.

The technical solution of the utility model provides the anti-open system of a kind of fire exit door, it comprises the fire exit door that the door-plate split by two fans consists of, it is characterized in that: two described door-plates are provided with unduplicated numbering by disposable easily broken lock ring locking on the described disposable easily broken lock ring.This disposable easily broken lock ring is a kind of common plastic products, often be applied to the occasions such as container locking, it has the design of a frangibility, can not reduce thereby after being subject to certain external force and pullling, can disconnect, the coding that prints when also having manufacturer production on it, the unique corresponding lock ring of coding.

Preferably, two described door-plates all are fixedly installed L shaped dead bolt, all offer the lockhole of perforation on the two described dead bolts, and described disposable easily broken lock ring passes head and the tail clamping behind the two described lockholes.

Preferably, described fire exit door limit also is provided with the monitoring camera over against described fire exit door.

The anti-open system of fire exit door of the present utility model adopts common disposable easily broken lock ring with the fire exit door locking, be provided with unique numbering on this lock ring, therefore as long as check in daily inspection whether lock ring is destroyed, whether numbering change, thereby learn whether this fire exit door was opened, cooperate corresponding monitoring video can detect whom and when open this fire exit door.The utility model is the anti-open system of low, the effective fire exit door of a kind of cost.

Description of drawings

Fig. 1 is the structural representation of the anti-open system of fire exit door of the present utility model;

Fig. 2 is the structural representation that dead bolt and easily broken lock ring cooperate.

The specific embodiment

The below is described in further detail the specific embodiment of the present utility model.

As shown in Figure 1, the anti-open system of a kind of fire exit door of the present utility model comprises fire exit door 12, two door-plates 10 that the door-plate 10 split by two fans consists of by disposable easily broken lock ring 14 lockings, and fire exit door 12 limits also are provided with the monitoring camera 16 over against fire exit door 12.

As shown in Figure 2, two door-plates 10 all are fixedly installed L shaped dead bolt 18, two dead bolts 18 and are fixed on the door-plate 10 by modes such as screws on one side, all offer the lockhole 20 of perforation on the vertical part of giving prominence to, and disposable easily broken lock ring 14 passes the 20 rear head and the tail clampings of two lockholes.This disposable easily broken lock ring 14 is a kind of common plastic products, often be applied to the occasions such as container locking, it has the design of a frangibility, can not reduce thereby after being subject to certain external force and pullling, can disconnect, the coding that prints when also having manufacturer production on it, the unique corresponding lock ring 14 of coding.Certainly, not unique effect of monitoring of also can realizing of encoding at will can not obtain because disposable easily broken lock ring 14 is for anyone, but effect is slightly poor.

So just can check in daily inspection whether lock ring 14 destroyed, whether numbering change, thereby learn whether this fire exit door was opened, cooperate corresponding monitoring video can detect whom and when open this fire exit door.

Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.

Claims

1. the anti-open system of fire exit door, it comprises the fire exit door that the door-plate split by two fans consists of, it is characterized in that: two described door-plates are provided with unduplicated numbering by disposable easily broken lock ring locking on the described disposable easily broken lock ring.

2. the anti-open system of fire exit door according to claim 1, it is characterized in that: two described door-plates all are fixedly installed L shaped dead bolt, all offer the lockhole of perforation on the two described dead bolts, and described disposable easily broken lock ring passes head and the tail clamping behind the two described lockholes.
