Abstract
The utility model relates to a door controller capable of controlling a door to keep the states of opening and closing, which is characterized in that the utility model is composed of a connection rod mechanism and a spring, wherein the connection rod mechanism is composed of a long and a short connection rods which are mutually hinged, both ends of the connection rod mechanism are respectively hinged with a door fixing plate (3) and a door frame fixing plate (6), and the spring (7) is arranged between the long connection rod (1) and the door frame fixing plate (6). The utility model has the advantages of simple structure, convenient installation and durability.
Description
The utility model relates to the annex of door, and particularly a kind of energy control gate is held open, the gating device of closed condition.
Existing gating device kind is a lot, as Spring hinge formula gating device.It is a mounting spring on the bearing pin of loose-leaf, though this gating device is simple in structure, makes spring stress excessive because its arm of force is as short as very much, causes the damage of spring easily, reduces application life.In addition, the insufficiency of this gating device, it can only keep closed condition by control gate, can not be held open state by control gate.
The purpose of this utility model is the deficiency that exists in the above-mentioned background technology in order to solve, propose a kind of simple in structure, durable in use, control gate is held open the gating device of closed condition freely.
At the foregoing invention purpose, the utility model adopts following technical scheme.A kind of gating device, its special character is, it is made of linkage and spring, described linkage is made of long connecting rod (1) and short connecting rod (2), one of long connecting rod (1) with short connecting rod (2) one is hinged, the other end of long connecting rod (1) is hinged with the doorframe fixed head (6) that is fixed in the doorframe upper end, and the other end of short connecting rod (2) is hinged with the door fixed head (3) that is fixed on the door, between long connecting rod (1) and doorframe fixed head (6) spring (7) is housed.
The utility model is simple in structure, and is easy for installation, and it can be directly installed on the top at a back side, freely control gate be held open, closed condition, that is: the back door that pushes the door open can be closed voluntarily, door is shifted onto door can keep to the side automatically when keeping to the side the position, its spring stress is little, and is durable in use.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of doorframe fixed head 6.
Fig. 3 is the left view of a fixed head.
Referring to figs. 1 through Fig. 3, linkage of the present utility model is made of long connecting rod 1 and short connecting rod 2, between long connecting rod 1 and the short connecting rod 2 one hinged by pin 4, the other end of long connecting rod 1 is hinged by pin 4 and doorframe fixed head 6, the other end of short connecting rod 2 is hinged with door fixed head 3 by pin 4, a spring pin 5 is arranged on doorframe fixed head 6, a spring pin 5 is also arranged on the lever arm of long connecting rod, two of spring 7 is separately fixed on these two spring pins 5.
