Horizontal distance less than the second mounting hole and doorframe horizontal distance；Prolong in the center of gravity direction of second connecting rod towards railing door frame
It stretches, so that the center of gravity of entire railing door frame is tilted towards the direction that handrail door is closed, so that can after pushing handrail door to open
It is closed from the skew direction rotation automatic resetting of trend center of gravity.Structure is simple, is easily installed, at low cost.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the handrail door provided by the embodiment of the utility model that automatically resets.
Specific embodiment
One kind automatically resets handrail door, as shown in Figure 1, including doorframe 1 and the railing door frame that is mounted on doorframe；Railing
Door frame is connected by first connecting rod 4, the second connecting rod 5, third connecting rod 6, the 4th connecting rod bar 7 and 8 head and the tail of the 5th connecting rod
It connects and surrounds；The first support plate 2 and the second support plate 3,2 He of the first support plate are arranged at intervals between railing door frame and doorframe 1
One end of second support plate 3 is each attached on doorframe；The section of first support plate 2 is rectangle, and the section of the second support plate 3 is
L shape；
It is provided with the first mounting hole passed through for first connecting rod 4 in first support plate 2, is provided in the second support plate 3
The second mounting hole passed through for first connecting rod 4；Using be parallel to railing door frame mounting surface direction as horizontal direction, with hang down
It is directly vertical direction in the direction of the mounting surface of railing door frame, the second mounting hole is relative to the first mounting hole further from handrail door
Frame；The vertical range of first mounting hole and doorframe 1 less than the second mounting hole and doorframe 1 vertical range, the first mounting hole and
Horizontal distance of the horizontal distance of doorframe 1 less than the second mounting hole and doorframe 1；Weight of second connecting rod 4 towards railing door frame
Heart direction extends；
It is clearance fit between first mounting hole, the second mounting hole and first connecting rod；First mounting hole is connect with first
The first limiting device is provided between bar；The second limiting device is provided between second mounting hole and first connecting rod.
Specifically, the structure of the first limiting device and the second limiting device is fixed ring, fixed ring includes first fixed
Ring and third fixed ring, the first fixed ring are fixed on the top for being located at the first mounting hole on first connecting rod；Third fixed ring is solid
It is scheduled on the top for being located at the second mounting hole on first connecting rod；Pass through the fixed first connecting rod 4 of the effect of fixed ring and doorframe 1
Relative position.Further, for the position of further fixed first connecting rod 4, fixed ring further includes the second fixed ring
With the 4th fixed ring, the second fixed ring is fixed on the lower section for being located at the first mounting hole on first connecting rod, and the 4th fixed ring is fixed
It is located at the lower section of third mounting hole in the second connecting rod.
The automatically reset principle that automatically resets of handrail door of the present embodiment is to pass through the phase in the first peace ancestral hole and the second mounting hole
Contraposition installs and the setting of the extending direction of the second connecting rod, so that the center of gravity of entire railing door frame is towards handrail door
Closing direction, when exerting a force split handrail door, handrail door is automatic towards the side for closing handrail door under the action of the center of gravity of deflection
To deflection.Therefore the principle that automatically resets of the utility model handrail door is to be the deflection of center of gravity, the concrete shape knot of handrail door
Structure can have any shape, it is only necessary to ensure center of gravity deflection.
The concrete shape of railing door frame as an example, as shown in Figure 1, third connecting rod is parallel with the 5th connecting rod
Interval setting, the length of the length of third connecting rod less than the 5th connecting rod；Railing door frame is an integral molding structure.
The embodiments of the present invention is elaborated above in conjunction with drawings and examples, but the utility model
It is not limited to the above embodiment, within the knowledge of a person skilled in the art, this can also not departed from
It changes or changes under the premise of utility model objective.
