Abstract
The utility model relates to a device which is directly arranged on an ordinary door to enable the door to automatically open and close slowly. The device can automatically close the door by moving, extending and contracting a draw rod in a straight mode and can stop the door in the range of 90 DEG to 100 DEG and use atmospheric pressure to realize buffering during the door closing process. In the utility model, the draw rod at the inner section of a cylinder body is sheathed with a pressure spring, and the draw rod is enabled to extend and shrink relatively to the cylinder body to realize the automatic door closing purpose. When a positioner rotates around a pin shaft, a steel ball in the positioner can be automatically sprung into a positioning notch on a cantilever to realize the automatic stop of the door. An 'air cylinder' structure is used, and a regulating screw is used for controlling the discharging speed of the pressed gas to realizes buffering. The utility model can be directly arranged on various ordinary wood doors to realize automatic buffering door closing purpose.
Description
The utility model relates to a kind of directly being installed on the common door, makes a device that the energy automatic slowly is closed.
It is the door catapult that power is made that the automatic door closing device that uses on common door, major product have torsion spring.Effectively 2 deficiencies are arranged though this device is simple, the one, no buffer, it is fast to close a speed, and door and doorframe are clashed into; The 2nd, can not stop door automatically.
In order to address this problem, the general practice is to adopt hydraulic oil to make buffer medium.Make fluid pressure type horizontal type door closer (being commonly called as " day dragon ").This device can be realized effectively cushioning and close door automatically.But this device makes housing, piston, rotating shaft, end cap, adjustment screw owing to guaranteeing that internal hydraulic pressure oil uses to prevent to leak repeatedly ... etc. the manufacture process requirement height, difficulty of processing is big.Simultaneously, this device must become torsion in the rotating shaft to the thrust of spring through gear rotation, again through two pull bars, converts the pulling force that door is closed to, makes the shell length restriction of originally experiencing be difficult for bigger by the spring function loss of standard manufacture.In addition, it stops door automatically is to rely on the angle of two pull bars to adjust, and reliability is relatively poor in the use.At present, the horizontal type door closer mostly is top-grade building and uses, and common door is used less.
The purpose of this utility model is will be for common door provides a kind of straight moving rod-pulling type pressure buffer automatic door closing device, and it can rely on the directly moving flexible Men Bingneng that closes automatically of pull bar to make door stop door automatically and effectively utilize the buffering that air pressure is realized a process of closing at 90 °-100 ° reliably.
The purpose of this utility model is achieved in that fixes a cantilever that positioning recess is arranged on a side door frame, have the locator that spring and steel ball are equipped with in a centre to link to each other with bearing pin with cantilever.Fix and stretch into the pull bar of cylindrical shell with locator, in the cylindrical shell internal end cover to being with a stage clip between the piston.With cylindrical shell afterbody gummed silently on a disappointing road by adjustment screw control is arranged.When door is pushed open, be installed in tailstock a to distance between bearing pin that upward connects silently and increase, pull bar is pulled out from cylindrical shell, and the drive locator rotate around bearing pin with door.When door reached 90 °-100 °, steel ball sprang into positioning recess in the locator, realized stopping automatically door.The whole process stage clip that opens the door stores power.When pulling after door makes steel ball skid off the cantilever positioning recess, the power that stage clip stores discharges automatically, makes pull bar retraction cylindrical shell, drives door and closes.Simultaneously, because the pull bar retraction makes the piston motion that leather cup is housed, cause air pressurized in the cylindrical shell, the pull bar retraction is obstructed.The disappointing road of pressurized air through adjustment screw control is arranged slowly emits, and closes thereby force pull bar to drive door lentamente.
The utility model uses " inflator " structure to cushion because the flexible direct control gate of use pull bar and stage clip is closed, and therefore, structure is simple especially.Because the medium of buffering is an air, does not need to resemble to be closed the hydraulic oil repeatedly and use.For this reason, manufacturing process becomes very simple and convenient.In addition, in the long cylindrical shell, directly make pull bar stressed because stage clip can be packed into, not only the function loss is few, and the effect of door is closed in realization automatically easily, and stage clip easily adopts the standard method manufacturing.Moreover the cantilever positioning recess is fixed, locator with pull bar when bearing pin rotates, spring into recess naturally as long as forward positioning recess position steel ball to, therefore, realize stopping automatically door easily exactly.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the front elevation view according to the straight moving rod-pulling type pressure buffer automatic door closing device that the utility model proposes.
The concise and to the point working condition of the concrete device that foundation the utility model proposes is described below in conjunction with Fig. 1.
This device comprises a cantilever (1) that is screwed on doorframe, with the locator that is attached thereto (5), locator (5) is fixed with pull bar (7) end, pull bar (7) stretches into cylindrical shell (10) can stretching motion take place with cylindrical shell (10), tailstock (15) on cylindrical shell (10) afterbody has silently (17) and is fixed on door links to each other, silently (17) go up design adjustment screw (19), can regulate cushion effect.
Fig. 2 is that locator is in and stops a state among the figure according to the locator profile of the straight moving rod-pulling type pressure buffer automatic door closing device that the utility model proposes.
Describe details and working condition according to the locator that the utility model proposes in detail below in conjunction with Fig. 2.
This device comprises a cantilever (1) that is screwed on doorframe, be designed with a positioning recess (21) on the cantilever (1), there is a locator (5) to be connected with bearing pin (2) with cantilever (1), spring (4) and steel ball (3) are housed in the locator (5). Insert pull bar (7) and fixing with rivet (6) in locator (5) hole.
When opening the door, pull bar (7) is when moving with door, (among the figure from dotted line along arrow direction) drives locator (5) and rotates around bearing pin (2), during positioning recess (21) position on forwarding cantilever (1) to, (this figure solid line position), door just in time reaches 90 °, and the steel ball (3) in the locator (5) springs into positioning recess (21) under spring (4) effect, stops door to be closed automatically, though this mode is simple, and is in full force and effect.Can guarantee accurately to stop door.
Fig. 3 is according to the straight moving rod-pulling type pressure buffer automatic door closing device main body profile that the utility model proposes.
Describe details and working condition according to the concrete device that the utility model proposes in detail below in conjunction with Fig. 3.
This device comprises a pull bar (7), and pull bar (7) stretches in the cylindrical shell (10) from end cap (8) hole that is fixed on cylindrical shell (10) end with screw (9). The upper cover of the pull bar (7) of cylindrical shell (10) inner segment has a stage clip (11), and there is screw thread on pull bar (7) top.
