Abstract
The utility model relates to a safety device for holding door open, which is composed of a base, an elastic steel plate, a rivet, a pin, a pin shaft, a support rod and a rubber plunger. The utility model is arranged on the lower corner of a door. When the utility model is used, the support rob is pedaled and rotates around the pin shaft on the base to fall. With the triangular stability principle, the door is positioned at any opening angle by the friction of the rubber plunger and the ground surface as a support, so the door is prevented from being rebounded under the action of a door closer, a return spring or wind power and the damage is avoided. Especially, the utility model can avoid the phenomenon that persons can not escape because the door is blocked in an emergency. The utility model has simple and visual structure and very strong reliability, which is suitable to be popularized in the existing doors.
Description
The utility model relates to a kind of door unlatching and locatees gating device (international Patent classificating number EO5C17/44) at any angle, particularly a kind of safe permanent seal cooling door top.
Door does not have the location gating device in the prior art, particularly door closer is being housed, back-moving spring and the door of wind effect is arranged, when making door, needs are open at when arbitrarily angled, generally feel inconvenience, and fragile door and annex address this problem usually and stop with weight or voussoir, or installation bolt-type, the gating device of sucked type or friction-type, these objects or device or because of heaviness, or unreasonable because of designing, easily lost efficacy, easy to wear.Dangerous reliable when not only using, the personnel's foot of easily damaging, and this series products also lacks under emergency door and in time opens evacuation personnel's norm of construction and require and function.Therefore present most of doors are not popularized yet and are used gating device.
The purpose of this utility model is to provide a kind of simple and easy durable, and convenient directly perceived and door that have an emergency release function is opened arbitrarily angled gating device--the safety door top.
The purpose of this utility model is achieved in that (as shown) safety door top by base (1), and elastic steel sheet (2), rivet (3), bearing pin (4), pole (5) and rubber stopper (6) are formed.Base (1) with the screw more than 3 on the certain position of door inferior horn.The end that pole (5) has the cam cusp has a hole, connects with base (1) by bearing pin (4), and bearing pin (4) is fixed in two fixing earholes of base (1).The base plate central authorities of base (1) have through hole, and in the groove of this hole bottom the flexible steel disc of rivet clasp (2).When the cam end of pole (5) is rotated around bearing pin (4), and the cam cusp can oppress the open and flat fixing elastic steel sheet in through hole bottom surface (2) locking pole (5) when being transferred to the center through hole of base (1), and pole this moment (5) is in the off position that stops.When needs control door at an arbitrary position the time, the other end of fastening rubber stopper (6) of gently pedaling pole (5) with pin is downward, at this moment, the cam cusp of pole (5) breaks away from the compressing locking of elastic steel sheet (2), and the other end freely falls, and by rubber stopper (6), contact and scrape along the ground, constitute a fulcrum, another fulcrum then is that the bearing pin (4) and the base (1) of cam cusp end supports door, makes its location.A this end is fixed on the door inferior horn, and the other end freely is supported on the door top on ground, and in case of emergency, whether personnel can take door into account and locate.And, push door open optionally along the door opening direction, and at this moment, rubber stopper one end of pole (5) is then opened with door and is dragged, and does not produce any stopping, and personnel can force the way to and escape, and have therefore realized the emergency release function on this top effectively.
For solving the endurance issues of gating device, the function that the utility model is focussed in particular on the component on above-mentioned door top designs as follows:
1, the bottom surface of the center through hole of base (1), designed groove especially, this groove is crossed over center through hole, and join on one side and to be drilled with rivet hole, make elastic steel sheet (2) can pass through rivet (3) rivet clasp in groove, make elastic steel sheet (2) and rivet (3) all recessed in groove, not the plane of outstanding base.And can allow elastic steel sheet (2) that a deformation space is arranged when pressurized.The another side that the another side of elastic steel sheet (2) abuts in base (1) center through hole open and flatly can avoid the free end of the cam cusp of pole (5) and elastic steel sheet (2) stuck, has improved the functional reliability on door top.
2, three above fixing screw hole two ends of base (1) periphery, special design spill flake hole, by the bottom surface on one side can hold the fifth wheel of screw when fastening, the concave pit by plane on the base plate can make fastening screw be deeply buried in and avoid the personnel of damaging in the plate level.
3, specially designed bearing pin (4) is one and has the step axle of different-diameter or the elastic shaft with radial tension that is rolled by elastic steel sheet, its purpose is that bearing pin (4) can be fixed in two fixing earholes of base (1) effectively and does not rotate with pole (5), also can not improve the useful life longevity on door top effectively along its axial float.
4, the connected mode with pole (5) and rubber stopper (6) is specifically designed to the screw threads for fastening type, promptly be designed to the hole, garden that has internal thread hole or internal thread hole is arranged, and have corresponding external screw thread or cooperate with the rubber stopper (6) of bolt at the free end of pole (5).Can effectively rubber stopper (6) be fixed in the free end of pole (5), the weakness of having avoided when supporting ground, rolling distortion easily and having come off and lost efficacy, simultaneously especially with the axis tilt of the axis of the rubber consent of pole (5) and pole (5) angle, make the end face energy of rubber stopper (6) smooth, increased frictional force in ground.
The utility model is because of mainly focusing on the structure function design of product, the mechanics angle and the patience at each position have particularly been improved, therefore be the strong door top of the high fastness of a kind of reliability, be well suited for the requirement of door positioning control in the existing building, have the value of large-scale popularization.
Concrete structure of the present utility model is provided by accompanying drawing.
