Description
Technical field
The present invention relates to a kind of safety door sill, the position limiting structure on particularly a kind of New-type safety door hurdle.
Background technology
At present, pass in and out specific place in order to prevent that baby, child or toy are careless, but people are provided with a closing door frame bottom usually on the doorframe of door, and have the safety door sill of certain altitude.
Safety door sill on the market generally comprises doorframe and door hurdle two parts now, and the door hurdle is to be fixed on the doorframe through door-hinge, can rotate around axle, and establish locking device, thereby realize opening the door and closing the door function.But the Generally Recognized as safe door is in the process of opening the door, in case after the locking bolt on the door hurdle broke away from the lockhole of doorframe, the door hurdle left doorframe and random court easily
Front or rear side opens, and uses inconvenience, to above-mentioned shortcoming, is necessary to make improvement.
The utility model content
In order to overcome the deficiency of prior art, the present invention provide a kind of rational in infrastructure, safeguard function good and the position limiting structure on New-type safety door hurdle easy to use.
The technical solution adopted for the present invention to solve the technical problems is:
The position limiting structure on a kind of New-type safety door hurdle comprises left and right doorframe, has a hurdle that its right side and right doorframe are movably hinged; Said left-hand door frame inside is provided with connecting rod, and this connecting rod lower end is connected with the left-hand door frame bottom through spring, and said left-hand door arch is provided with flange; Said left-hand door frame upper end is provided with locating part, it and movable spacing connection of small end; On locating part, be provided with and the relative lockhole of door hurdle left surface, be provided with the inclined-plane in the said lockhole, said door hurdle left surface is provided with and the corresponding elasticity locking bolt of locating part; When locating part is descended by driving force, form the breach that the elasticity locking bolt is spacing between locating part end face platform and the flange.
Wherein, said small end is provided with bar-shaped trough, and said locating part stretches into bar-shaped trough and movable spacing connection of connecting rod through pin.
In addition, said locating part is a cambered surface to the side in the left side, hurdle of answering the door.
In addition, said left-hand door frame is provided with the foot rest that links to each other with connecting rod.
In addition, the end face on said inclined-plane is the spill cambered surface.
The invention has the beneficial effects as follows: when the door hurdle that needs will be closed is opened; Driving locating part through actuator descends; The termination of the elasticity locking bolt in left side, door hurdle receives the extruding on inclined-plane in the locating part lockhole and in lockhole, withdraws from; After withdrawing from again because the elastic reset effect extend in the breach that forms between locating part end face platform and the flange, and locating part withstands the elasticity locking bolt through the end face platform under flexible effect, make hurdle can not receive this moment from gravity arbitrarily forward, the rear opens automatically; And need its direction of opening of user's sliding door hurdle control, very convenient to use; At closing time, door hurdle power effect is outside closed up towards the left-hand door frame, and the elasticity locking bolt in left side, door hurdle receives the extruding of left-hand door frame locating part end face to return and extend in the lockhole, realizes closing the door; Simultaneously, the present invention when opening the door owing to need to drive locating part through foot-operated, thereby increased the difficulty that child or toy are opened the door hurdle, make safety door sill reach better security protection effect.

The specific embodiment
Referring to figs. 1 through Fig. 4, the position limiting structure on a kind of New-type safety door hurdle comprises left and right doorframe 1,2; There is a hurdle 3 that its right side and right doorframe 2 are movably hinged; Said left-hand door frame 1 inside is provided with connecting rod 4, and these connecting rod 4 lower ends are connected with left-hand door frame 1 bottom through spring 5, and said left-hand door frame 1 top is provided with flange 7; Said left-hand door frame 1 upper end is provided with locating part 6, it and movable spacing connection of connecting rod 4 upper ends; On locating part 6, be provided with and the relative lockhole 8 of door hurdle 3 left surfaces, be provided with inclined-plane 9 in the said lockhole 8, said door hurdle 3 left surfaces are provided with and locating part 6 corresponding elasticity locking bolts 10; When locating part 6 is descended by driving force, the formation breach 13 that elasticity locking bolt 10 is spacing between the end face of locating part 6 (15) and the flange 7.
As the specific embodiment of the present invention, said connecting rod 4 upper ends are provided with bar-shaped trough 11, and said locating part 6 12 stretches into bar- shaped trough 11 and 4 movable spacing connections of connecting rod through pinning.
Operating principle of the present invention is: when the door hurdle that needs will be closed is opened; Driving locating part 6 through actuator descends; The termination of the elasticity locking bolt 10 in door 3 left sides, hurdle receives the extruding on inclined-plane 9 in locating part 6 lockholes 8 and in lockhole 8, withdraws from; After withdrawing from again because in the breach 13 that forms between the end face (15) that the elastic reset effect extend into locating part 6 and the flange 7, locating part 6 withstands the elasticity locking bolt through the spill cambered surface of end face (15) under flexible effect, make a hurdle can not receive at this moment from gravity arbitrarily forward, the rear opens automatically; And need the user with its direction of opening of hand push door hurdle control, very convenient to use; At closing time, door hurdle power effect is outside closed up towards the left-hand door frame, and the elasticity locking bolt 10 in left side, door hurdle receives the extruding of left-hand door frame 1 locating part 6 end faces to return and extend in the lockhole, realizes closing the door; Simultaneously, the present invention when opening the door owing to need to drive locating part through foot-operated, thereby increased the difficulty that child or toy are opened the door hurdle, make safety door sill reach better security protection effect.
In the present invention, the answer the door side in 3 left sides, hurdle of 6 pairs of said locating parts is a cambered surface; Slip in the lockhole 8 of locating part 6 sealed through globoidal structure be convenient to the to close the door elasticity locking bolt 10 on process Zhong Men hurdle 3.
In the present invention, said left-hand door frame 1 is provided with the foot rest 14 that links to each other with connecting rod 4; Can drivening rod 4 through trampling foot rest 14, locating part 6 descends, and plays the effect of opening the door hurdle equally, and is very convenient to use.
In the present invention, the end face on said inclined-plane 9 is the spill cambered surface, and this structure can make the spill cambered surface at the trivial bolt 10 of elasticity 9 tops on the inclined-plane just and not put and squint.
The present invention is rational in infrastructure, easy to use, has fine safeguard function, is a kind of position limiting structure that is widely used in safety door sill.
