Abstract
The invention discloses a safe doorknob, which is specially designed for preventing the accidental closing of an opened door. The safe doorknob is composed of a handle, a connection column and a base, wherein the handle and the connection column are fixedly connected with a 90-degre angle; and the safe doorknob is characterized in that an inner hole is formed at one end of each of the handle and the connection column, a columnar insertion element is arranged in the inner hole, one end of the columnar insertion element is inserted in the inner hole of the handle, the other parts are exposed at the outer end of the handle to form the extended end of the handle, and the lengths of the exposed parts of the columnar insertion element are greater than the distance from the doorknob to one side of a door; and in the case that the opened door is accidentally closed, the columnar insertion element is blocked between the door and a doorframe, so that a certain gap is generated between the door and the doorframe, thus the effect of the safe doorknob is achieved.
Description
Affiliated technical field
The present invention relates to a kind of building finishing and use door handle, more specifically, relate to a kind of safety door handle.
Technical background
Door is the article that all can contact every day, and can bring people injury sometimes also.For example young child reaches door handle, can directly open the door with hand; Sometimes the head of a family does not notice child after one's death at closing time, can crush child's finger yet; Sometimes indoor wind can be shut door suddenly, if at this moment our hand is just wanting to buttress doorframe, consequence is hardly imaginable; When also having children to play on the door limit, situation about jamming a finger also happens occasionally.Existing door handle can't stop the generation of above-mentioned situation because of reasons in structure.
Summary of the invention
Safety door handle of the present invention designs for addressing the above problem, and this safety door handle can prevent the door opened, when closing because of accident, can not close fully, and leave one section space, eliminates because of the door accident and closes all rough sledding of bringing.
Safety door handle of the present invention, it is made up of handle 1, joint pin 2 and base 3, and handle 1 is fixedly connected for 2 one-tenth 90 ° with joint pin; It is characterized in that: the end that handle 1 connects with joint pin 2 has an endoporus 4; Endoporus 4 has a column plug-in unit 5, and an end of column plug-in unit 5 is inserted in the endoporus 4 of handle, and remainder is exposed at the handle outer end; Become the extended end of handle, the length of exposed part surpasses handle 1 to a close side door ore deposit distance.
In technique scheme, preferably, said column plug-in unit is the hard rubber goods.

Specific embodiment
In order more to be expressly understood above-mentioned purpose of the present invention, feature and advantage, the present invention is further described in detail below in conjunction with the embodiment accompanying drawing and the specific embodiment.
Below be to have set forth concrete details in the instance so that make much of the present invention, still, the present invention can also adopt other to be different from other modes described here and implement, therefore, the present invention is not limited to the restriction of following disclosed specific embodiment.
The technical scheme that embodiment 1 narrates the safety door handle is following: the present invention provides a kind of safety door handle; Comprise base 3, joint pin 2 and handle 1 composition; One end of handle 1, promptly there is an endoporus 4 end that is connected with joint pin 2 of handle 1, and an end of column plug-in unit 5 inserts endoporus 4; Column plug-in unit 5 becomes the reverse extending part of handle 1, column plug-in unit 5 expose length outside handle 1 greater than door closure state the time handle 1 to the distance of adjacent doorframe.
The embodiment of the enforcement of present embodiment 1 is: when door closure state, handle 1 is horizontal, and column plug-in unit 5 also becomes horizontal as the extended end of handle; Because of column plug-in unit 5 expose length outside handle 1 greater than door closure state the time handle 1 to the distance of adjacent doorframe; Hinder to the unlatching of door, with handle 1 rotation, column plug-in unit 5 also rotates run-off the straight with it as the extended end of handle 1; Cross doorframe, door is opened smoothly.After door is opened; Column plug-in unit 5 resets with handle 1 and resets; When the door accident is closed, because of column plug-in unit 5 expose length outside handle 1 greater than door closure state the time handle 1 to the distance of adjacent doorframe, column plug-in unit 5 can block between door and the doorframe; Thereby make door and doorframe generation certain clearance, played because of the door accident and closed the personal injury that causes or the sight of all inconvenience.
When door is closed; The doorframe width greater than handle to door apart from the time, column plug-in unit 5 is had any problem when implementing, embodiment 2 has done further design to this kind situation; On basic design and embodiment 1 essentially identical basis, improve; As shown in Figure 2, in column plug-in unit 5 and endoporus 4 bottoms one gap is arranged, a spring 6 is equipped with in the crack during this time.
The embodiment of embodiment 2 is: when at door closure state, the width of doorframe greater than handle 1 to door apart from the time, column plug-in unit 5 is under the extruding of doorframe, the spring 6 in the compression endoporus 4 is pressed into the redundance of column plug-in unit 5 in the endoporus 4.In the time must opening door; With handle 1 rotation; Column plug-in unit 5 also rotates run-off the straight with it as the extended end of handle 1, because of the disengaging doorframe extruding of column plug-in unit 5, ejects to exterior portions under the effect of the spring 6 of column plug-in unit 5 in handle endoporus 4; Prolonged the length of exposing outside handle 1, make column plug-in unit 5 expose length outside handle 1 greater than door closure state the time handle 1 to the distance of adjacent doorframe.After door is opened and is opened; Column plug-in unit 5 resets with handle 1 and resets; When the door accident is closed, because of column plug-in unit 5 expose length outside handle 1 greater than door closure state the time handle 1 to the distance of adjacent doorframe, column plug-in unit 5 can block between door and the doorframe; Thereby make door and doorframe produce certain clearance, play the effect of safety door handle.
More than column plug-in unit 4 among two embodiment be to adopt the tartan manufacturing.
