A kind of construction elevator protective door

Technical field

The utility model relates to a kind of door, relates in particular to a kind of protective door that uses when being used to elevator is installed.

Background technology

In the construction work progress in building, default lift port is accident area occurred frequently often.Some elevators are not before installing, and elevator door is not installed door, have only some simple warning facilities, and sometimes the workmen is lifting weight, and grogginess is fixed, just might accident fall into.And so common obstacle piling on the contrary and can impact normal construction at some construction elevator mouths that often use, and is unfavorable for normally carrying out of engineering.For under the premise that security is guaranteed, making that construction elevator is unobstructed carries out, in August, 2004 is disclosed, publication number be the utility model " safety protective door of architecture construction cage lifter discharging platform " of CN2630385 just disclosed a kind of have the people walk terraced from the time advantage that close door, thoroughly provide against hidden trouble in ground can the utmost point time protective door.But just elevator door cuts out in this utility model, and not locking fully, closed even close, also might meet accident, for example elevator starts, and the outer people of elevator wants in a hurryly still the door of outside to be opened, and this moment, the elevator of the inside was movable, like this with regard to dangerous generation.Situation about also having be the workmen when waiting for elevator, also door may be opened, the labour contractor is insinuated in the door and peeps, and is easy to cause the accident!

The utility model content

The purpose of this utility model provides a kind of construction elevator protective door, can in time elevator door be pinned, and in case pinning can only be opened by inside, the personnel that avoided the outside is because the possibility that meets accident accidentally.Simultaneously also guarantee the unobstructed of construction elevator, accomplished safety and satisfactory to both parties easily.

For reaching described effect, a kind of construction elevator protective door of the utility model comprises the protective door doorframe, and protective door is connected with the protective door doorframe by the spring reverse motion that is located at the one side, and protective door is provided with lockset, and lockset is positioned at the protective door inboard.

Preferably, described protective door is a tambour door structure, and described lockset is between two fan sliding doors.The spring reverse motion of described construction elevator protective door comprises the pedestal that is fixed on the protective door doorframe, connects a unsettled cross bar on the pedestal, and hard spring is enclosed within on the cross bar, and is connected with protective door.

Preferably, described protective door is the sliding door structure, the spring reverse motion of described lockset described construction elevator protective door between protective door and protective door doorframe comprises the pedestal that is fixed on the protective door doorframe, connect a depression bar with spring on the pedestal, depression bar is pressed on the protective door under action of the spring.

Owing to adopted described structure, the set spring reverse motion of a kind of construction elevator protective door of the utility model can in time cut out protective door after personnel leave.And protective door be provided with lockset protective door is closed after directly with on the door lock, and the personnel of outside can not be opened, avoided because the accident that maloperation brings.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the inboard scheme drawing of the tambour door structure of a kind of construction elevator protective door of the utility model.

Fig. 2 is the inboard scheme drawing of the sliding door structure of a kind of construction elevator protective door of the utility model.

The specific embodiment

This uses novel a kind of construction elevator protective door, comprises protective door doorframe 1, it is characterized in that: protective door 2 is connected with protective door doorframe 1 by the spring reverse motion 3 that is located at the one side, and protective door 2 is provided with lockset 4, and lockset 4 is positioned at protective door 2 inboards.

As shown in Figure 1, be the situation of described protective door 2 during for tambour door structure, described lockset 4 is between two fan sliding doors.The spring reverse motion 3 of described construction elevator protective door comprises the pedestal 31 that is fixed on the protective door doorframe 1, connects a unsettled cross bar 32 on the pedestal 31, and hard spring 33 is enclosed within on the cross bar 32, and is connected with protective door 2.

When elevator puts in place, need open lockset 4 by the people that elevator is promptly taken in elevator inside, and draw back protective door 1.Because hard spring 33 is enclosed within on the cross bar 32, and is connected with protective door 2, this moment, hard spring 33 was in compressive state on cross bar 32.When the staff left, protective door 2 is SELF CL under the effect of hard spring 33, and lockset 4 also cuts out the back at protective door 2 and pins automatically.Therefore lockset 4 is positioned at protective door 2 inboards, can only be opened by the elevator inboard, and the outer personnel of elevator just can not go owing to maloperation enters in the elevator door that elevator do not put in place like this.

As shown in Figure 2, described protective door 2 is the sliding door structure, the spring reverse motion 3 of described lockset 4 described construction elevator protective door between protective door and protective door doorframe comprises the pedestal 31 that is fixed on the protective door doorframe 1, connect a depression bar 35 with spring 34 on the pedestal 31, depression bar 35 is pressed on the protective door 2 under spring 34 effects.

When elevator puts in place, need open lockset 4 by the people that elevator is promptly taken in elevator inside, and push protective door 1 open.Owing to connect a depression bar 35 with spring 34 on the pedestal 31, depression bar 35 is pressed on the protective door 2 under spring 34 effects, and spring 34 is in compressive state.When the staff left, spring 34 promoted depression bars 35 and makes protective door 2 SELF CL, and lockset 4 also cuts out the back at protective door 2 and pins automatically.Therefore lockset 4 is positioned at protective door 2 inboards, can only be opened by the elevator inboard, and the outer personnel of elevator just can not go owing to maloperation enters in the elevator door that elevator do not put in place like this.

But convenience safety simple in structure has like this accomplished that in work progress safety with satisfactory to both parties easily, has improved workman's work efficiency, has also ensured workman's safety.
