Door shield
Technical field
The utility model relates to a kind of door shield that limiting door is opened scope that is used for, and belongs to the field of building equipment.
Background technology
The parts of indispensability in the most of families of door shield, door shield in the market mainly is to be fixed near the ground, wall limit, in the time of the door complete opening, because door shield is between door and metope, therefore, door shield can prevent directly contact metope of door well, especially prevents when opening the door with bigger strength the damage that the handle bump metope on the door causes metope.But present door shield mainly is to be positioned near on the ground or metope in corner, people trip because of carelessness easily, simultaneously also be unfavorable for keeping the attractive in appearance of whole room, many spaces have also been taken, therefore, press for a kind of space that can effectively utilize on the market and be not easy to hinder the door shield of people's activity again.
Summary of the invention
The utility model provides a kind of door shield, hinders people's activity to solve the conventional door block resistance, is unfavorable for keeping the attractive in appearance of whole room, has taken the defective in many spaces.
The structure of door shield of the present utility model is as follows: it comprises " L " type fixture and the block piece that is fixed on " L " type fixture one end, the other end of " L " type fixture is fixed on the doorframe upper edge of a top, " L " type fixture one end that comprises block piece is positioned at the rear side of door, and below and block piece least significant end that block piece protrudes on plane, " L " type fixture place are lower than a plane at place, top.Can make door shield can be securely fixed on the doorframe upper edge by such structure design, simultaneously, block piece on the door shield protrudes " L " type fixture below, the scope of activities of limiting door effectively, promptly when door is pushed can be blocked after reaching certain angle by the block piece on the door shield, simultaneously because door shield is the rear side that is fixed on the doorframe upper edge and is positioned at door, the general people's activity in this zone is less, after door is opened simultaneously, door shield is blocked, neither can trip people, also can not destroy the attractive in appearance of integral body on metope or the ground, also effectively utilize the space simultaneously as being installed in.
Because in most cases, the door shield that people are provided with generally is between the angular range of 90 to 180 degree in the door radius of action, the scope of activities of coming limiting door is at the angular range of 0 to 180 degree, and further, " L " type fixture bending place angle theta is 90 to spend to 180 degree.
Under more common situation, it generally is 0 to spend to 120 degree that people require the angular range of limiting door activity, and further, " L " type fixture bending place angle theta is 150 degree.Like this, under the maximum situations of opening 120 degree of door, the scope of activities that door shield still can limiting door.
In order to be fixed on " L " type fixture on the doorframe upper edge securely, further, " L " type fixture is fixed on the doorframe upper edge by fixing threaded hole on the end and hold-down screw.
The impact force of bump door shield when opening in order to alleviate door further, also has elastic body on the block piece.
Further, elastic body by screw block piece near the door a side on.
The beneficial effect of door shield of the present utility model is: by this door shield, because the secret of installation site can not hinder people's activity, can keep the attractive in appearance of whole room simultaneously, utilize the space well.

The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
Be respectively the front view and the lateral view of the utility model door shield as depicted in figs. 1 and 2.It comprises " L " type fixture 1 and the block piece 2 that is fixed on " L " type fixture 1 one ends, there are four to be the fixing threaded hole 3 that positive direction distributes on the other end of " L " type fixture 1, and this end of " L " type fixture 1 is fixed on the doorframe upper edge 8 of door 7 tops by four hold-down screws 6, " L " type fixture 1 one ends that comprise block piece 2 are positioned at the rear side of door 7, and block piece 2 protrudes the plane that below and block piece 2 least significant ends on plane, " L " type fixture 1 place are lower than door place, 7 top.Block piece 2 is fixed on " L " type fixture 1 by screw 4, and in the present embodiment, flexible body 5 on the side of close door on the block piece 2.Elastic body 5 can be to be fixed on the block piece 2 by screw 4.
Because in most cases, the door shield that people are provided with generally is between the angular range of 90 to 180 degree in the door radius of action, the scope of activities of coming limiting door is at the angular range of 0 to 180 degree, " L " type fixture bending place angle theta can be set be 90 and spend to 180 degree.
Under more common situation, it generally is 0 to spend to 120 degree that people require the angular range of limiting door activity, " L " type fixture bending place angle theta can be set be 150 degree.Like this, under the maximum situations of opening 120 degree of door, the scope of activities that door shield still can limiting door.
Be illustrated in figure 3 as the structural representation after the utility model door shield is installed.Door shield 1 is installed on the doorframe upper edge 8 by hold-down screw, and at this moment, because 7 angles that unlatching is very little of door, door shield 1 does not have the activity of barrier door 7.
Be illustrated in figure 4 as the utility model door shield the structural representation of back and limiting door scope of activities is installed.Door shield 1 is installed on the doorframe upper edge 8 by hold-down screw, and the maximum angles of door 7 approaching unlatchings this moment, door shield 1 prevent that by the further unlatching that block piece 2 and elastic body in the above come barrier door 7 door 7 from touching metope.
Below only be specific embodiment of the utility model, any those skilled in the art can think variation all drop within protection scope of the present invention.
