Abstract
The utility model discloses an automatic door closing device which comprises a pulley fixed on a door frame, a hauling rope and an elastic reset device, wherein the hauling rope bypasses the pulley; one end of the hauling rope is fixedly connected with a door leaf and the other end is provided with the elastic reset device; the elastic reset device comprises a tension spring; and one end of the tension spring is fixed on the door frame through a door frame fixing seat, and the other end of the tension spring is connected with the hauling rope. The device is mounted between the door frame and the door leaf; after a person passes the door, the door leaf is closed automatically and immediately; and the indoor temperature is guaranteed in cold seasons, and the device is particularly suitable for workshops, ranches or public places. The automatic door closing device is simple in structure, convenient to mount, and high in practicability.
Description
Technical field
The utility model relates to a kind of being fixed on and is used for controlling the device that door and window is closed, specifically a kind of door engine on door and window.
Background technology
Existing common door is connected with doorframe by hinge, need to realize by manpower the switch of door.Although automatic door can open and close automatically when the people arrives and leaves, what be convenient for people to passes through, and the cost of automatic door is higher, and its range of application is limited to.Especially in plant, the workman frequently passes in and out drill shack winter, and not noting in time closing the door to cause the drill shack temperature to reduce, directly affect the health of livestock and poultry in drill shack, brings unnecessary trouble to enterprise.
The utility model content
The purpose of this utility model is to provide a kind of door engine, is installed between doorframe and door leaf, and after people passed through, door leaf is autoshutdown immediately.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of door engine comprises the pulley, pull rope and the elasticity reset device that are fixed on doorframe, and pull rope is walked around pulley, and an end is fixedly connected with door leaf, and the other end is provided with elasticity reset device.
Described elasticity reset device comprises an extension spring, and extension spring one end is fixed on doorframe by the doorframe holder, and the other end of extension spring is connected with pull rope.
The beneficial effects of the utility model are:
The utility model is installed between doorframe and door leaf, and after people passed through, door leaf shut immediately automatically, has guaranteed interior temperature in the cold time, is particularly useful for factory floor, feed lot or public arena and uses.The utility model is simple in structure, and is easy for installation, practical.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the reference diagram of use state of the present utility model;
Fig. 2 is the partial structurtes enlarged diagram of Fig. 1.
In figure: 1, door engine; 2, doorframe; 3, floor; 4, door leaf; 5, body of wall; 11, doorframe holder; 12, pulley; 13, pull rope; 14, door leaf holder; 15, iron nail; 16, extension spring.
The specific embodiment
As shown in Fig. 1 to 2, a kind of door engine 1 comprises the pulley 12, pull rope 13 and the elasticity reset device that are fixed on doorframe 2, and pull rope 13 is walked around pulley 12, one ends and is fixedly connected with door leaf 4, and the other end is provided with elasticity reset device.
Described elasticity reset device comprises an extension spring 16, and extension spring 16 1 ends are fixed on doorframe 2 by doorframe holder 11, and the other end of extension spring 16 is connected with pull rope 13.
As preferably, door leaf holder 14 is set on door leaf 4, be convenient to being connected and fixed of pull rope 13.
Pulley 12 is fixed on doorframe 2 by iron nail 15.
As a reference, the installation site of the position relationship of floor 3, body of wall 5, doorframe 2 and door leaf 4 and door engine 1 as shown in Figure 1.
Operating principle and the using method of this door engine 1 are as follows: when the people opens behind the door, due to External Force Acting, the end that pull rope 13 is fixed in door leaf moves to the door leaf direction, drives extension spring 16 and stretches; After external force disappeared, extension spring 16 restored to the original state, and can drive the end that pull rope 13 is fixed in door leaf and move to doorframe holder 11 directions, and door leaf 4 is along with autoshutdown in the restorable process of extension spring 16.
The initial thinking of this device is to utilize the gravity of object and pulley to complete automatic door-closing, but when utilizing gravity, the movement travel of object is long, cause structure not compact, be not easy to actual installation and use, so it is changed as utilizing the elastic force of extension spring, can not only play so same effect, and compact conformation, more be conducive to install.
Above disclosed be only the specific embodiment of this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be considered as belonging to the utility model protection domain.
