The utility model discloses the mechanism is simple and convenient, the easily production manufacturing, and the practicality is strong, can provide safe and reliable's protective action for operating personnel.
Description
Technical field
The utility model relates to one and to automatically reset unilateral gate, belongs to technical field of safety protection.
Background technology
When work machine operation platform distance ground is higher, generally there is upper and lower staircase, ladder way mouth place person works and up and down time safety precaution comparatively special, most domestic adopts one hand to push open, the frame mode that after getting on, push-and-pull is closed again, there is larger potential safety hazard, need consider that certain safeguard procedures are to ensure that personnel are in the safety of ladder way mouth and operability.The ladder way mouth place unilateral gate of existing job platform can not automatically reset, and increases operating personal operational motion, easily produces danger of falling; Outside inhibiting device is exposed to, limiting stopper is engaged obviously with the rotation of door-hinge, more easily produces injury; On door, handgrip Partial Height is unreasonable, does not meet the Human Engineering Principle of supported at three point, and handrail contact site adopts steel pipe material, and sense of touch is chill.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is, provides one to automatically reset unilateral gate, and mechanism is easy, be easy to manufacture, practical, can provide safe and reliable protective action for operating personal.
The technical solution of the utility model is: one automatically resets unilateral gate, comprise two doorframe columns, wherein a doorframe column is provided with unilateral gate handrail bend pipe, it is characterized in that, be provided with between described doorframe column and unilateral gate handrail bend pipe and place side by side double torsion spring, the described two ends of placing side by side double torsion spring are provided with latch, and described doorframe column is provided with latch rotating shaft, and described latch inserts in latch rotating shaft; Described double torsion spring of placing side by side is wrapped with reset protective cover, is provided with the first circular hole inserted for unilateral gate handrail bend pipe and the second circular hole supplying to place side by side double torsion spring insertion in described reset protective cover.
Aforesaid one automatically resets unilateral gate, and it is characterized in that, described unilateral gate handrail bend pipe is bent into square.
Aforesaid one automatically resets unilateral gate, and it is characterized in that, described unilateral gate handrail bend pipe is provided with rubber handrail.
Aforesaid one automatically resets unilateral gate, and it is characterized in that, described double torsion spring of placing side by side is provided with locating dowel pin.
Aforesaid one automatically resets unilateral gate, it is characterized in that, described reset protective cover is provided with the 3rd circular hole stretched out for locating dowel pin.
Aforesaid one automatically resets unilateral gate, and it is characterized in that, the material of described unilateral gate handrail bend pipe is steel.
The beneficial effect that the utility model reaches:
1, utilize the stressed gyroscopic characteristics of placing side by side double torsion spring combination, by the potential energy of placing side by side double torsion spring, unilateral gate Rapid reset is closed, reduce operational motion, and avoid forgetting the danger of falling of closing the door and bringing;
2, increased the size in handrail region by styling design, when personnel stand on two stage steps position, staircase the top time, handrail horizontal or vertical on door can be grasped smoothly;
3, place side by side double torsion spring and be wrapped with reset protective cover, effectively prevent from crushing;
4, unilateral gate handrail bend pipe is provided with rubber handrail, overcomes the adverse effect that steel are chill, people is grasped safe comfortable when operation, and makes fence visually well arranged, can play warning function in operating environment.
Accompanying drawing explanation
Fig. 1 is that the utility model automatically resets the integral structure schematic diagram of unilateral gate;
Fig. 2 is that the utility model automatically resets the exploded view of unilateral gate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, one automatically resets unilateral gate, and comprise two doorframe columns 7, wherein a doorframe column 7 is provided with unilateral gate handrail bend pipe 2, the material of described unilateral gate handrail bend pipe 2 is steel, and size, position meet the Human Engineering Principle of supported at three point.Be provided with between described doorframe column 7 and unilateral gate handrail bend pipe 2 and place side by side double torsion spring 4, the described two ends of placing side by side double torsion spring 4 are provided with latch 8, and described doorframe column 7 is provided with latch rotating shaft 6, and described latch 8 inserts in latch rotating shaft 6.Utilize the stressed gyroscopic characteristics of placing side by side double torsion spring 4 and combining, by the potential energy of placing side by side double torsion spring 4, unilateral gate Rapid reset is closed, reduce operational motion, and avoid forgetting the danger of falling of closing the door and bringing.
Described double torsion spring 4 of placing side by side is wrapped with reset protective cover 3, is provided with the first circular hole 9 inserted for unilateral gate handrail bend pipe 2 and the second circular hole 10 supplying to place side by side double torsion spring 4 insertion in described reset protective cover 3.Place side by side double torsion spring 4 and be wrapped with reset protective cover 3, effectively prevent from crushing.
Described unilateral gate handrail bend pipe 2 is bent into square, described unilateral gate handrail bend pipe 2 is provided with rubber handrail 1, overcomes the adverse effect that steel are chill, people is grasped safe comfortable when operation, and make fence visually well arranged, warning function can be played in operating environment.
Described double torsion spring 4 of placing side by side is provided with locating dowel pin 5, and described reset protective cover 3 is provided with the 3rd circular hole 11 stretched out for locating dowel pin 5.Described locating dowel pin 5 pairs of unilateral gate closure states position, and can prevent doorframe and door from misplacing and produce safety hazard.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
