Abstract
The invention discloses a simple spring door device capable of being automatically closed. The simple spring door device comprises a door pillar, a torsion spring, a wearable pad, a door bracket as well as a positioning ring plate and a supporting plate which are welded and fixed on a door frame, wherein a short tube is welded in a supporting plate hole to form the door bracket for supporting the door pillar. During installation, the door pillar penetrates through the positioning ring plate and then is dropped on the supporting plate which is padded with the wearable pad. The door pillar is a hollow steel tube, and the torsion spring is arranged in the steel tube. A fixing ring at the upper end of the spring is fixed with the door pillar through a pin. The length of the pins is a bit greater than the diameter of the door pillar tube. Therefore, after the installation, the door pillar can be prevented from being drawn out of the positioning ring. A fixing ring at the lower end of the torsion spring is inserted into a narrow slot in the upper part of a spring regulator which penetrates in from the lower surface of the door bracket. After the resilience force degree of the door is regulated to the best state by rotating the regulator, the door and the door bracket are fixed through the pin. The simple spring door device is relatively simple in structure and manufacturing, and parts such as the torsion spring are completely sealed in the door pillar tube, so that the corrosion due to exposure to sun and rain can be effectively prevented. Meanwhile, the effect of automatically closing the door after entering the door is reliably realized.
Description
Technical field
The present invention relates to a kind of swinging door, particularly relate to a kind of automatic closing spring door gear with easy structure.
Background technology
At present, the assembly of devices of closing the door for automatic rebounding after opening the door is more, but also have be closed to finally can hommization, dolcissimo, function closed gently.But this type of spring closing device is all applicable to being contained in enters the room on the door of an inner side or indoor.But for the large-scale mining of Year-round Operation under the adverse circumstances such as mine is on-the-spot, the protective guard such as platform, aisle arranged on defeated, heap reclaimer device to enter door then improper.Traditional method, does not generally all have automatic door-closing function, need close artificially.Or adopt an extension spring to close the door.So all can bring inconvenience and danger to user.
Summary of the invention
The present invention, in order to overcome the defect of above-mentioned traditional method, provides a kind of easy, the swinging door device that can automatically close.The technical scheme that the present invention is achieved is: comprise door pillar, and door pillar lower end is welded with a door end ring plate, and the location ring flat-plate be weldingly fixed on doorframe and supporting plate.Be welded with a brachymemma pipe in described supporting plate hole, form the Fomento seat that is lifted door pillar.During installation, door pillar drops on through location ring flat-plate and is lined with on the supporting plate of wear-resistant pad.Described door pillar is hollow steel tube, is provided with a torque spring in steel pipe.The retainer ring of spring upper end is fixed by pin and door pillar.The length of pin is slightly longer than door pillar pipe diameter.So, the situation generation preventing column and extract from locating ring can be played after installing simultaneously.
The retainer ring of described torsionspring lower end, should insert in the narrow groove on the spring adjuster top upwards penetrated below Fomento seat.Turn after the resilience dynamics of door is transferred to optimum state by adjuster at plate, by pin, fix together with Fomento seat.
Compared with prior art, the invention has the beneficial effects as follows:
Structure, make comparatively simple, the component such as torsionspring are all shut in door pillar pipe, the corrosion that can effectively prevent from outdoor from exposing to the sun and rain causing.Meanwhile, reliably achieve enter after the effect of automatic door-closing.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail.
The present invention mainly make use of door pillar (1) for circular hollow steel pipe, torsionspring (3) can be put into steel pipe, and meanwhile, the outer wall of round steel pipe and endoporus can be used as the feature of rotating door-hinge.As shown in Figure 1, location ring flat-plate (9) and supporting plate (10) are welded in the corresponding position of doorframe respectively.After assembling, door pillar, by location, location ring flat-plate (9), makes door can only rotate in locating ring, but can not move horizontally.Door pillar lower end is welded with a door end ring plate (4), and stand on supporting plate (10), supporting plate (10) carries the total weight of whole door.Be lined with a wear-resistant pad (5) between the door end ring plate (4) of supporting plate (10) and door pillar lower end, its effect is the wearing and tearing reduced when door rotates steel plate.
As shown in Figure 1, the upper end ring portion of torsionspring (3), by a pin through door pillar, fixes torsionspring (3) and door pillar.The two ends length of pin, slightly larger than door pillar pipe diameter, makes it respectively to expose, and is close to locating ring lower plane, upwards extracts from location ring flat-plate (9) with limiting door column.
The upper end of described spring adjuster (7) has one can stored in the tubbiness recess of one section of torsion spring spring body.Cross center, end, direct-axis is to having a narrow groove.
The retainer ring of described torsionspring (3) lower end inserts from the narrow slit of spring adjuster (7) end that Fomento seat pipe (6) upwards loads.Meanwhile, the lower end part spring body of torsionspring (3) is also just in time in the recess of spring adjuster upper end, better locates to enable spring.Spring adjuster 7 loads length to Fomento seat, should exceed Fomento seat pipe (6), a part in introduction of going forward side by side column lower end pipe.Located to make door pillar and Fomento seat.Play the effect that can only rotate and can not misplace.
After torsionspring adjuster installs to the degree of depth, first turn torsionspring adjuster by the closing direction plate of door, when the screen resilience adjusting to door is suitable, and the pin-and-hole on the pin-and-hole of spring adjuster and Fomento seat pipe is to timing, is loaded onto by pin.Now, swinging door is in normal operating condition.
Although invention has been described for composition graphs above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing under aim of the present invention, can also make a lot of distortion, these all belong within protection of the present invention.
