Abstract

The utility model discloses a torque-type automatic door closer, which comprises a triangular positioner which is installed on a door frame, a stress seat which is installed on a door sector and a bending-type torsion shaft, wherein an extending end of the triangular positioner is provided with a torsion cylinder which can be used for mounting a torsion spring, the stress seat is provided with a shaft hole, the bending-type torsion shaft is of a sleeved connection form, a pressure spring is installed inside the sleeved connection hole, and a torsion spring is installed inside the torsion cylinder; and one end of the bending-type torsion shaft is inserted into the revolving drum, and another end is inserted into the stress seat. One end of the torsion spring is fixed on the revolving drum,and another end is fixed on the bending shaft. The torque-type automatic door closer has simple structure and good stability. Since the installation position of the stress seat is far away from a doorshaft, the power arm is large when the automatic door works, so that the door closing effect is better.

Description

Torsion-type automatic door closer

Technical field

The utility model relates to the door in house.

Background technology

Existing house door all is made up of doorframe, door leaf and door.All be by human hand push door at closing time, very inconvenient.Especially in public, the switch of door is frequent, this often occurs and closes the door and the situation of not closing the door, and brings inconvenience for people's live and work.In order to realize closing the door automatically, also can hang over a spring on the door leaf, but like this, not only damage door leaf but also not attractive in appearance, bigger at the noise that produces at closing time.Door closer in the market is various, and pluses and minuses are all respectively arranged, and door check of the present utility model is different with existing door closer structure on the market.

The utility model content

The purpose of this utility model provides a kind of novel torsion-type automatic door closer.

The structure of the utility model torsion-type automatic door closer is: comprise being installed in leg-of-mutton locator and the stressed seat and the folding type torsion shaft that are installed on the door leaf on the doorframe, the external part of triangle locator is provided with the torsion tube that the torsion spring can be installed, stressed seat is provided with axis hole, the folding type torsion shaft is a socket joint type, pressure spring is housed in the sleeve joint hole, the torsion spring is housed in the torsion tube; Folding type torsion shaft one end inserts in the rotating cylinder, and the other end inserts stressed seat.One end of torsion spring is fixed on the rotating cylinder, and the other end is fixed on the folding type torsion shaft.Thereby solve the range deviation of the generation of a bit rotating, but also help the closure of door around the two different centers of circle.During the work of torsion-type automatic door, torsion spring generation deformation reaches the effect of closing the door automatically.

The utility model has the advantages that: simple in structure, better stable.The installation site of stressed seat is far away apart from door-hinge, and the power arm during automatic door work is bigger, thereby makes the better effects if of closing the door.

Description of drawings

Further specify structure of the present utility model below in conjunction with the drawings and specific embodiments.

Marginal data: 1---door leaf, 2---doorframe, 3---locator, 4---the torsion spring, 5---the torsion tube, 6---the folding type torsion shaft, 7---compression spring, 8---rotating cylinder, 9---stressed seat.

The specific embodiment

As shown in the figure, the utility model comprises the triangle locator 3 that is installed on the doorframe 2 and the stressed seat 9 and folding type torsion shaft 6, compression spring 7 and rotating cylinder 8 compositions that are installed on the door leaf 1, the external part of triangle locator 3 is provided with the torsion tube 5 that torsion spring 4 can be installed, stressed seat 9 is provided with axis hole, folding type torsion shaft 6 is a socket joint type, pressure spring 7 is housed in the sleeve joint hole, torsion spring 4 is housed in the torsion tube.Folding type torsion shaft 6 one ends insert in the rotating cylinder 8, and the other end inserts stressed seat 9; One end of torsion spring 4 is fixed on the rotating cylinder 8, and the other end is fixed on the folding type torsion shaft 6.

Claims

1, a kind of torsion-type automatic door closer, it is characterized in that, comprise and be installed in leg-of-mutton locator and the stressed seat and the folding type torsion shaft that are installed on the door leaf on the doorframe, the external part of triangle locator is provided with the torsion tube that the torsion spring can be installed, stressed seat is provided with axis hole, the folding type torsion shaft is a socket joint type, and pressure spring is housed in the sleeve joint hole, and the torsion spring is housed in the torsion tube; Folding type torsion shaft one end inserts in the rotating cylinder, and the other end inserts stressed seat, and an end of torsion spring is fixed on the rotating cylinder, and the other end is fixed on the folding type torsion shaft.
