Abstract
The utility model relates to a door side resistance device which consists of a groove mounted on a door frame, an extension strip, a spring and an extension groove which are mounted on a door sheet, wherein the extension strip is sleeved in the spring and arranged in the extension groove, and makes extension motion in the extension groove through the spring. The door side resistance device facilitates door opening and closing.
Description
One, technical field
The utility model relates to the door leaf fastening devices, especially a kind of limit resistance device.
Two, background technology
At present, the door of most of classroom, every day is all between Kai Heguan, because loose between door leaf and the doorframe, door closes not tight, is opened once blowing by wind, want door tight, just must be keeper tightly or lock, still, sometimes have the classmate late again, after locking, the classmate has come, go again to open the door, very inconvenience, even, some people simply in Men Bianyong paper and adhesive tape thickening, increases frictional force.
Three, summary of the invention
The purpose of this utility model provides a kind of limit resistance device, can obviously improve the frictional force between door leaf and the doorframe, makes things convenient for the Push And Release of classroom door.
The technical scheme that the utility model is taked is:
It constitutes by being installed in the groove on the doorframe and the expansion strip, spring and the telescopic chute that are installed on the door-plate, and described expansion strip is enclosed within the spring and is located in the telescopic chute, and by spring at the telescopic chute telescopic movable.
Because the utility model is equipped with groove at doorframe, expansion strip is installed on the door-plate, at closing time, expansion strip touching doorframe and in the indentation telescopic chute; When its alignment indentation, expansion strip just puts in groove, by the fixing door leaf of the frictional force between expansion strip and the groove, can make things convenient for the Push And Release of classroom door.
Four, description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is product structure schematic diagram of the present utility model.
Sign in the accompanying drawing is represented respectively:
1. groove 2. doorframes 3. expansion strips 4. door leafs 5. springs 6. telescopic chutes
Five, the specific embodiment
As can be seen from Figure 1, the utility model constitutes by being installed in the groove 1 on the doorframe and being installed in expansion strip 3 on the door-plate, spring 5 and telescopic chute 6, and described expansion strip 3 is enclosed within the spring 5 and is located in the telescopic chute 6, and passes through spring 5 at telescopic chute 6 telescopic movables.
During manufacturing, groove 1 and telescopic chute 6 are provided with hole, have dug notch respectively at door leaf 4 and doorframe 2 correspondence positions, are separately fixed at doorframe 2 and door leaf 4 edges by screw.Groove 1 will be complementary with expansion strip 3 sizes.
During use, close the door: expansion strip 3 touching doorframes 2 and in the indentation telescopic chute 6, when its alignment indentation 1, expansion strip 3 just puts in groove 1, by the fixing door leaf 4 of the frictional force between expansion strip 3 and the groove 1; Open the door: apply certain thrust or pulling force, promote or pulling door leaf 4, expansion strip 3 just puts in groove 1 and can open the door.
