The safety door guardrail has reasonable mechanical structure and stability, accuracy and in place of automatic door closing.
Description
Technical field
The utility model relates to a kind of safety door guardrail.
Background technology
The doorframe of door grate mainly is to rely on an inclined-plane that revolves in the seat to cooperate with the inclined-plane of rotating seat junction to finish with open and close door resetting means between the door-plate, door-plate leaves the back and utilizes the inclined-plane that revolves in the seat to close the door automatically, because power is light, tend to cause closing the door slowly or situation about can't close the door automatically, make troubles to people.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of mechanical structure reasonable, automatically stable at closing time, accurately, the safety door guardrail that puts in place.
The technical scheme that the utility model adopted is:
A kind of safety door guardrail, comprise doorframe and door-plate, the top of doorframe vertical tube is equipped with holder, door-plate is fixed with rotating seat in the relevant position, and rotating seat rotates and is installed on the holder, and the bottom of described holder and rotating seat junction respectively is provided with the inclined-plane, the transverse tube of described doorframe bottom is provided with axis hole, the door-plate bottom is provided with the axis of rotation that stretches in the axis hole, and the portion of stretching into of axis of rotation is arranged with power assistant spring, and the axis of rotation lower end is fixed with nut.
Further improvement of the utility model, the opposite side of described doorframe and door-plate is provided with the locking mechanism of working in coordination, described locking mechanism comprises the switch holder that is fixed on the doorframe and is fixed in switches set on the door-plate, and switches set is provided with hand-reset and pulls button and automatically reset and pull button.
Further improvement of the utility model, four corners of described doorframe respectively are provided with the screw rod adjustment seat.
The beneficial effects of the utility model are: door-plate upwards promotes under the effect of inclined-plane fit structure when pushing the door open, axis of rotation also promotes synchronously, because the portion of stretching into of axis of rotation is arranged with power assistant spring, thereby power assistant spring also pressurized simultaneously, when unclamping door-plate, the door-plate utilization automatically resets and closes the door under the elastic force of inclined-plane that focuses on rotating seat and bottom power assistant spring promotes, the design's door panel structure is stressed more reasonable, effort to close is big, speed is fast, thereby has also guaranteed to stablize more at closing time, put in place.

The specific embodiment
Referring to figs. 1 through shown in Figure 9, a kind of safety door guardrail, comprise doorframe 1 and door-plate 2, the top of doorframe 1 vertical tube is equipped with holder 3, door-plate 2 is fixed with rotating seat 4 in the relevant position, rotating seat 4 rotates and is installed on the holder 3, holder 3 respectively is provided with inclined- plane 31,41 with the bottom of rotating seat 4 junctions, the transverse tube of doorframe 1 bottom is provided with axis hole 11, door-plate 2 bottoms are provided with the axis of rotation 21 that stretches in the axis hole 11, the portion of stretching into of axis of rotation 21 is arranged with power assistant spring 22, and axis of rotation 21 lower ends are fixed with nut 23.。
Operating principle: when people push door-plate 2 open, because the bottom with the holder cooperation place of rotating seat 4 is inclined-planes, therefore, in process was opened the door in rotation, door-plate 2 can promote gradually, and the axis of rotation 21 that drives the bottom moves up synchronously, power assistant spring 22 is compressed under the acting in conjunction of nut 23 and transverse tube inner surface, when unclamping hand, door-plate 2 utilizes under the elastic force of inclined-plane that focuses on rotating seat and bottom power assistant spring promotes and automatically resets and close the door
Further, doorframe 1 is provided with the locking mechanism of working in coordination with the opposite side of door-plate 2, locking mechanism comprises the switch holder 5 that is fixed on the doorframe 1 and is fixed in switches set 6 on the door-plate 2, switches set 6 be provided with hand-reset pull the button 61 and automatically reset pull the button 62, button is pulled in the pulling hand-reset when opening the door, make locking bolt 63 break away from switch holder 5, door is pushed open.Unclamp the hand Rear Door and automatically reset and close, be reset to corresponding to switch holder 5 positions when door-plate drives switches set 6, automatically reseting to pull to pull makes in the holder of the laterally inserted pass of locking bolt, realizes locking a door.
For make door grate can the scope of application wider, the design respectively is provided with screw rod adjustment seat 7 in four corners of doorframe 1, the adjusting screw(rod) of screw rod adjustment seat can be adjusted in the horizontal direction.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
