Abstract
The utility model discloses a house gate, which in particular to a tension spring damper which one of preventing mosquito and fly screen door tension springs. The damper comprises a gas cylinder pipe, a unidirectional bucket valve, and a draw rod. The utility model is characterized in that the damper is provided with a circular pipe cylinder pipe; the unidirectional bucket valve is installed in the gas cylinder pipe in assorting mode; the unidirectional bucket valve is fixedly connected with one end of the draw rod; the draw rod is installed in sliding fit mode with the opening of one end of the gas cylinder pipe; one end of the tension spring is connected with the end of the cylinder pipe, and the other end is connected with the fixing junction which is installed on the draw rod. When the door is opened and used, the unidirectional bucket valve is pulled from the left end of the gas cylinder to the right end; the unidirectional bucket valve prolongs the tension spring to prompt the gate has a restoring force; when the door is closed, under the effect of the restoring force of the tension spring, the gate prompts the unidirectional bucket valve to restore from right end to the left end; at this time, the elastic piece of the unidirectional bucket valve plugs up the small production well of the unidirectional bucket valve to make the valve increase left restoring force damping; consequently, the damping achieves the purpose of closing the door at low speed.
Description
Affiliated technical field
The utility model relates to a kind of door of house, especially a kind of extension spring damper of mosquito screen door extension spring.
Background technology
At present, the widely used extension spring of closing the door, restoring force is very big when closing the door, and can produce very big noise, simultaneously, also takes place easily to squeeze to hinder accident, though also there is relevant apparatus to occur, all complex structure costs an arm and a leg, and does not also have good solution at present.
Summary of the invention
In order to solve the shortcoming of the extension spring of closing the door at present, the utility model provides a kind of extension spring damper, and this extension spring damper can solve the big problem of restoring force at closing time, noise is low, can not take place to squeeze to hinder accident, and it is simple in structure, price is very low, and suitable especially family popularizes use.
The technical scheme that its technical problem that solves the utility model adopts is: this damper comprises cylinder tube 4, one-way piston valve 5 and pull bar 6 three parts, it is characterized in that: this damper has the cylinder pipe 4 of a tubular, in cylinder tube 4, cooperate one-way piston valve 5 is housed, one-way piston valve 5 is fixedlyed connected with an end of pull bar 6, pull bar 6 is installed with the opening sliding fit of cylinder tube 4 one ends, and extension spring 7 one ends are connected with the end of cylinder pipe 4, and the other end is connected with fixedly knot 8 on being installed in connecting rod.Open the door when using, one-way piston valve and the left end in cylinder tube 4 pull to right-hand member, extension spring 7 is prolonged, impel Men Zi that the power of an answer is arranged, at closing time, under the ground effect of extension spring restoring force, impel one-way piston valve 5 to be returned to left end from right-hand member, at this moment, the flexure strip 5-1 of one-way piston valve 5 has blocked the little venthole of one-way piston valve 5, make this valve increase the damping of replying left, thereby reach the purpose of closing the door at a slow speed.
Its beneficial effect is: this extension spring damper can solve the big problem of restoring force at closing time, and noise is low, can not take place to squeeze to hinder accident, and it is simple in structure, and price is very low, and suitable especially family popularizes use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural principle schematic diagram of the present utility model.
Among the figure, a 1. top base, 2. connecting rod, 3. venthole, 4. cylinder tube, 5-1. flexure strip, 5. one-way piston valve, 6. pull bar, 7. extension spring, 8. fixing knot.
The specific embodiment
In the drawings, the left end of cylinder tube 4 is a connecting rod 2, and it connects with door top base 1 hinge that is installed on the door, the internal diameter of cylinder tube 4 is isometrical circular siphunculus, the left end of circular siphunculus has a little gas outlet 3, and it is controlling passing through of compressed gas trace, thereby gives and resistance of extension spring; The right-hand member of circular siphunculus has an opening in the cylinder tube 4, and the external diameter sliding fit of this opening and pull bar 6 is installed.
In the drawings, fixing knot 8 is connected with the external diameter sliding fit of pull bar 6, and it is fixed by Screw and pull bar.Its effect is the length of regulating extension spring 7, regulates the pulling force of extension spring.
