Abstract
The utility model discloses an air type spring, comprising an upper and a lower shell, a cam, a planker component and a returning mechanism, wherein the cam comprises a main axis and an eccentric wheel, the planker component comprises an upper and a lower planker and a locating pulley assembly, the eccentric wheel is arranged between the upper and the lower plankers, the upper and the lower plankers are connected with the returning mechanism which an air cylinder. The utility model is applicable to open, close and locate the tempered glass doors and the doors which need automatic close, not only having the advantage of making the door close automatically without external force exerted after opening the door with external force, wherein the door has a good locating function in the place 90 degree to the original and closes evenly, and is independent on the environment temperature thereby being used under extremely low temperature, and also having the advantages of simple structure, easy assembling, and universal application.
Description
Technical field
The utility model relates to a kind of part of door and window, refers in particular to a kind of with the floor spring that can be positioned certain angle and can close the door automatically after the door unlatching.
Background technology
The resetting means of the floor spring of producing in the market and using is generally the mode that spring adds oil hydraulic cylinder.This mode component are more, complex structure assembles loaded down with trivial detailsly, and easily causes less stable because component are many, durable inadequately, life-span is short, and oil hydraulic cylinder is because its medium freezing point is higher, when using under the environment of lower temperatures such as north of china in winter, easily make the oil hydraulic cylinder cisco unity malfunction, cause to reset undesirablely, the phenomenon of leakage of oil may appear in oil hydraulic cylinder in use for some time, easily pollutes.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of air-pressure type floor spring simple in structure is provided.
The purpose of this utility model is achieved in that a kind of air-pressure type floor spring, comprise lower house, cam, carriage component, resetting-mechanism, cam mainly is made of main shaft and eccentric wheel, carriage component mainly comprises planker, location pulley combination up and down, the eccentric wheel of cam partly is located at up and down between the planker, planker is connected with resetting-mechanism up and down, and described resetting-mechanism is a cylinder.
Described cylinder is with being connected of planker is that screw connects up and down.
Described going up in the lower house is provided with holder, and the telescopic arm of cylinder is connected with holder by nut.
After the utility model had adopted above-mentioned structure, its component are few, and were easily assembled, can the extremely low area of adaptive temperature, adapt to wide.
Description of drawings
Below in conjunction with the specific embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross section structure schematic diagram of the present utility model;
Fig. 3 is the lateral view of first kind of shape of the utility model cam;
Fig. 4 is the vertical view of first kind of shape of the utility model cam.

The specific embodiment
Consult Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model air-pressure type floor spring comprises lower house 8, cam, carriage component and resetting-mechanism, and resetting-mechanism is a cylinder 5.Cam, carriage component, resetting-mechanism are located in the lower house 8, and cam is made of main shaft 1 and eccentric wheel 2, and carriage component is by planker 3, location pulley combination 4 constitute up and down.Main shaft 1 is socketed in the bearing 10 of lower house 8 upper and lower surfaces, and between the planker 3, between the planker 3, planker 3 passed through screw up and down about location pulley combination 4 was fixed on about eccentric wheel 2 was located at.Eccentric wheel 2 is provided with some alignment concavity, and alignment concavity matches with location pulley combination 4, can make main shaft 1 in-135 degree ,-115 degree ,-90 degree, 0 degree, 90 degree, 115 degree, 135 degree location.The cylinder body of cylinder 5 is fixedlyed connected by screw 12 with planker 3 up and down, is fixed with holder 6 in the last lower house 8, and the telescopic arm 7 of cylinder 5 is connected with holder 6 by nut 12.
Described cam can also be Fig. 5 and shape shown in Figure 6.
The utility model is when work, when the user opens the gate that is connected with main shaft 1, main shaft 1 begins to rotate, driving eccentric wheel fixed thereon 2 rotates, eccentric wheel 2 promotes location pulley combinations 4 and drives planker 3 rectilinear motions up and down, the cylinder 5 that links together with it of planker 3 compressions up and down, up to eccentric wheel 2 alignment concavity and locate pulley combination 4 carve mutually close after, the gate stops, and cylinder is in compressive state.When the user closes the gate, only need apply certain power, alignment concavity is no longer carved with location pulley combination 4 close, cylinder 5 planker 3 up and down pushes away, and location pulley combination 4 drives eccentric wheel 2 and rotates, and closes automatically up to the gate.
