Abstract

The utility model belongs to an improvement technology of an anti-theft door. The structure of the utility model is that the door is composed of a lift door at the inner side, a steel frame window at the outer part, and a transmission mechanism with hand operation. The side face of the lift door is provided with a gear strip which is connected with a chain wheel at the side face; the transmission mechanism with hand operation is composed of an automatic controller, a compound gear, a driving gear, a driven gear, and a chain wheel; the controller controls the driving gear and drives the chain wheel to rotate by the transmission of an intermediate gear; the lift door moves up and down by the driving of the gear strip; the steel frame window is arranged at the out part of the door, and the utility model has dual functions of closing and opening. The utility model has the advantages of simple structure; the door has a dual-layer structure; the utility model can be in an opening state when the weather is hot, and the utility model can be in a closing state when the whether is cold; the mechanical part of the utility model has flexible work and convenient use; the utility model is suitable for the use of enterprises and units and families, and the utility model has dual functions of ventilation and prevention.

Description

The difunctional door of interior transmission ascending/decending

The utility model and a kind of anti-improvement technology of forcing open the door.

At present, in various construction building, for the purpose of safety precaution, all adopt anti-forcing open the door for general room, anti-characteristics of forcing open the door are that the pick-proof performance is good, adopt firm metal sheet as shell body, the dead bolt of oscilaltion and the safety lock of gauge tap are equipped with in the centre, and anti-advantage of forcing open the door is sturdy and durable, and outstanding feature is that the strick precaution performance is good, metal sheet that outer package is firm and middle strengthening structure, its not enough aspect is that performance of ventilating is poor, and closure is good, and it is not smooth to form the room air circulation, sternly hot at summer weather especially, make troubles to indoor environment purification and life.

For solving the above anti-equal deficiency of knot of forcing open the door, the utility model purpose provides a kind of interior transmission ascending/decending difunctional door, and utilize in the door overhead door is housed, be the steelframe window outdoors, to realize safety precaution and ventilation dual-use function.The difunctional door of transmission ascending/decending in the utility model structure design is achieved in that, its structure is by inboard overhead door, outside steelframe window and hand transmission mechanism three parts are formed, detailed structure is that overhead door (as shown in Figure 1) is housed in the centre of door, around the overhead door is metal framework, roller all is equipped with on the framework both sides up and down, roller is set in the slide rail on both sides, slide rail is fixed on the both sides of door, and it is parallel with the overhead door both sides, between overhead door one side wheel, driving rack is housed, be vertically fixed on the frame of overhead door, mid portion is equipped with hand transmission mechanism on the right side of door, transmission mechanism is by controller, travelling gear, power transmission shaft and sprocket wheel are formed, its structure is that the controller outside is fixed cover, automatic catch is housed in the fixed cover, automatically the outside of catch is a ring spring, automatically catch outside exit and handle are fixed, the spring other end and rotation are pulled out bobbin and are fixed, pull out the bobbin external fixation driving gear is arranged, driving gear connects with driven gear by compound gear, and the driven gear center is a driven shaft, is fixed with sprocket wheel on the driven shaft simultaneously, adapter sleeve is equipped with in the sprocket wheel outside, installs and fixes the driving rack engagement of back sprocket wheel and overhead door; The outside of overhead door is the steelframe window, and the steelframe window is the first half that metal framework is welded on door, with following closure be one, it is inside and outside totally enclosed type that overhead door promotes the back, after overhead door was fallen, top was the ventilating board shelf structure, the bottom is an enclosed construction.

The utility model advantage: simple in structure, door is a double-decker, and day heat can be open state, and it is cold to be closed state, and its mechanical part work is flexible, easy to use, is fit to enterprises and institutions and family and installs and uses, and has ventilation and takes precautions against dual-use function.

The utility model detailed structure is provided by following examples and accompanying drawing.

Fig. 1 is the difunctional door schematic diagram of interior transmission ascending/decending;

Fig. 2 is the difunctional door of an interior transmission ascending/decending mechanical driving part structure chart.

Its structure is labeled as shown in drawings: 1. driving rack; 2. overhead door; 3. roller; 4. steelframe window; 5. slide rail; 6. hand transmission mechanism; 7. bobbin is pulled out in rotation; 8. driving gear; 9. compound gear; 10. sprocket wheel; 11. driven shaft; 12. adapter sleeve; 13. driven gear; 14. handle; 15. ring spring; 16. automatic catch; 17. fixed cover: 18. fixed mounts.

Difunctional door principle: hand crank rotates the automatic catch that is fixedly connected with it and rotates, automatically catch connects with one of spring end, next end of spring pulls out bobbin with rotation and links to each other, then spring one end rotates with catch, automatically catch is that the two sides symmetry all can drive spring and rotates to the left and right, spring rotates spring inside diameter is diminished, throw off with the external fixation cover, but be automatic catch left-right rotation, and driven rotary is pulled out bobbin and is done left-right rotation equally, by compound gear sprocket wheel is rotated to any direction, sprocket wheel is connected with the driving chain of overhead door, and the drive overhead door can move up and down, when handle stops to shake, and spring sets back, because the tension force and the fixed cover of spring closely cooperate, overhead door can be parked on any one lifting position.
