Abstract
The utility model discloses a door closing mechanism, particularly an automatic door closing mechanism which is arranged on a refrigerated displaying cabinet of a small sliding door with a sliding rail. The utility model is composed of the sliding door with a pulley, the sliding rail and the door closing mechanism thereof. The utility model has the key points that a notch is arranged on the lower part of the sliding door 1 of which the bottom is provided with the pulley 7, a tension spring seat 3 is arranged in the notch of the sliding door 1, and a tension spring 4 is arranged on the tension spring seat 3; one end of the center of the tension spring 4 is fixed on a limiting shaft in the tension spring seat 3, the other end of the tension spring 4 is fixed on the sliding rail 6 and keeps a certain tightness through an opening of the tension spring seat 3, and the sliding door 1 is freely arranged on the sliding rail 6. In this way, when the sliding door 1 is pulled towards one side, the tension spring 4 is tightly pulled; when the sliding door is not pulled, the sliding door immediately returns through pulling force of the tension spring.
Description
Technical field
The utility model relates to a kind of mechanism of closing the door, particularly a kind of door engine structure that is installed on the small-sized slide rail sliding door refrigerator display case.
Background technology
In order to attract the convenience of client and displaying, consumption, places such as existing bar, convenience store, dining room, supermarket all are placed with refrigerator display case.This kind refrigerator display case all is equipped with the glass slide sliding door of being convenient to open.This kind sliding door is to be made of the glass sliding door and the slide rail that have pulley.In order to reduce loss of refrigeration capacity, to make things convenient for customers, the door engine structure is housed all usually.But major part all relies on gravity or suspending hammer and similar structure, and this kind structure is installed trouble, and structure is corpulent, destroys the overall appearance of showcase easily.
Summary of the invention
The utility model is in order to overcome the shortcoming of above-mentioned door engine structure, a kind of compact overall structure, aesthetic in appearance to be provided, and is easy to install, the slide rail sliding door door engine structure that performance is preferable.
The utility model is achieved in that the sliding door by the band pulley, the slide rail and the mechanism of closing the door thereof constitute, the bottom that the sliding door of pulley is housed in the bottom has a notch, an extension spring seat is installed in the notch of sliding door, extension spring is installed in the extension spring seat, center one end of extension spring is fixed on the limit shaft in the extension spring seat, and the other end of extension spring then is fixed on the slide rail by the opening on the extension spring seat and keeps certain rate of tension, and sliding door freely is placed on the slide rail.
Above-mentioned sliding door is a kind of glass sliding door, and the pulley that install the bottom is a kind of wear-resisting pulley, and slide rail is a kind of slide rail of being made by resistant materials such as stainless steel or aluminium alloyss, and extension spring is made by the high-quality stainless steel belt.
The door engine structure that the utility model proposes is work like this: one side when pulling by external force when drawing back, extension spring is tightened up thereupon, when loosing one's grip, the pulling force of extension spring is taken back door immediately, has reached the purpose of closing the door automatically.The utility model is the brand-new design that is different from fully with upper type, has complied with current electrical appliance to trend economical and practical, development elegant in appearance, has demonstrated fully the design principles of convenience and practicability.In addition, the utility model compact overall structure, external form are little, easy to install, and performance is good and produce simply, cheap, is fit to continuous productive process in enormous quantities.
Description of drawings
Fig. 1 is a general illustration of the present utility model.
Fig. 2 is a broken section enlarged diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Two wear-resisting pulleys 7 are equipped with in bottom at glass sliding door 1, make glass sliding door 1 can be on stainless steel slide rail 6 horizontally slipping freely.Extension spring seat 3 usefulness stainless steel self threading pins 2 are fixed on glass reliably and pull in the mounting groove of 1 bottom, stainless steel extension spring 4 is placed in the extension spring seat 3, its center one end is fixed on the limit shaft in the extension spring seat, and the other end of extension spring 4 is fixed on the slide rail 6 with stainless steel self threading pin 5.When pulling 1 after one side is drawn back, extension spring 4 is tightened up thereupon, and when loosing one's grip, the pulling force of extension spring is taken back door immediately.
