Abstract

The utility model relates to an automatic positioning device. The utility model belongs to the device technical field of a wing fan moved to an opening or a closing position. The utility model is mainly composed of a slide channel, a bearing, a slide bar and a spring. The utility model has the structure that one end of the slide bar is fastened on the top end of a door leaf, and the other end is fixed with the bearing; the middle of the slide bar is provided with the spring; the slide channel is fixed on a door post and the slide channel corresponds to the position of the slide bar; the bearing slides on the slide channel; the slide channel forms an ace shape; the slide bar is a telescopic rod. The gate can automatically close without manpower. The utility model has the advantages of convenient use, safety, simple structure, low cost, etc.

Description

Automatic positioning equipment

The utility model relates to a kind of positioner of door leaf, belongs to the device technology field that wing moves on to unlatching or fastening position.

At present, generally adopt enclosure wall to be isolated from the outside around the office of China's constituent parts or around the place, the gate, access is provided with on enclosure wall.The gate that uses has two kinds, Power-driven gate or iron gate substantially; It is low high that Power-driven gate is made, and often breaks down and when having a power failure, the gate can not use, so the user is less; And therefore the iron gate uses comparatively general because cost is low, sturdy and durable.But the switch at iron gate all is artificial behaviors, therefore frequent switch causes labour intensity big, so frequent appearance is not closed the door or is forgotten the phenomenon of closing the door, when particularly depositing season in winter or cloudy raining, just more can't guarantee to shut the door after you, often not closing the door easily makes the people that a kind of sense of insecurity is arranged, and the condition that makes things convenient for of crime is provided also for the people that bad behavior is arranged.

The purpose of this utility model is the deficiency that remedies above-mentioned technology, provide a kind of need not be manually, the automatic positioning equipment that can close automatically of gate.

The utility model mainly contains slideway, bearing, slide bar, spring composition, and slide bar one end is fastened on the door leaf top, has spring, slideway to be fixed on the door pillar and with slide bar position in the middle part of the other end rigid bearing, slide bar and adapts, and bearing slides on slideway.

Slideway is an arc.

Slide bar is an expansion link.

Slide bar is movable in slideway.

The utility model in use, slide bar and door leaf one move, when door when closing, flexible slide bar all stretches out, and spring is in relaxation state, when door is opened (no matter inward or toward external-open), spring is compressed, this moment, bearing slided along track, and when door reached maximum, spring was in most compressed state; When staff leaves, be subjected to the effect of spring, bearing is prolonging slideway and is sliding to cutting out a direction, because slide bar and slideway diameter maximum at closing time, so the state that door loosens fully at the slide bar spring stops, also closes.

The utlity model has advantages such as easy to use, safe and reliable, simple in structure, that cost is low.

Below be description of drawings:

Fig. 1 is the utility model vertical view.

Fig. 2 is the utility model Slide bar structure schematic diagram.

Fig. 3 is the utility model stereogram.

Wherein: 1, slideway, 2, door pillar, 3, slide bar, 4, spring, 5, bearing, 6, the gate.

The utility model is described in further detail below in conjunction with accompanying drawing:

Structure such as Fig. 1, Fig. 2 and shown in Figure 3, slideway 1 can be manufactured by iron plate, curved shape, slide bar 3 is an expansion link, there is spring 4 at the middle part, slide bar one end is fastened on the top of door 6, other end rigid bearing 5, slideway are fastened on the door pillar 2, adapt with slide bar position, slide bar is movable in slideway, and bearing slides with moving of slide bar on slideway.During use, slide bar and door leaf one move, when door when closing, flexible slide bar all stretches out, spring is in relaxation state, and when door is opened (no matter inward or toward external-open), spring is compressed, this moment, bearing slided along track, and when door reached maximum, spring was in most compressed state; When staff leaves, be subjected to the effect of spring, bearing is prolonging slideway and is sliding to cutting out a direction, because slide bar and slideway diameter maximum at closing time, so the state that door loosens fully at the slide bar spring stops, also closes.
