Abstract
The utility model discloses a built -in floor spring, including the body, the inner chamber of body slides and is equipped with gyro wheel seat, connecting rod and piston, installs the camshaft on the body, is fixed with the cam on the camshaft, the one end of connecting rod is connected with the gyro wheel seat, and the pot head that the other end and hinge joint, connecting rod connect the piston has the spring, and this spring passes through the baffle and separates its and gyro wheel seat in different cavities, the camshaft is established in one side of connecting rod, and the cam of camshaft contacts with the gyro wheel seat, the utility model discloses a floor spring simple structure need not ground and digs the hole during installation, it is very convenient to install, moreover through the valve opening size control door open with closed speed, stability can be good.
Description
Technical field
The utility model relates to door closer, specifically a kind of built-in floor spring.
Background technology
In recent years, the living standard of people is become better and better, for the safe, attractive in appearance of living environment with facilitate the designing requirement of equipment more and more higher, though spring can realize automatic door-closing traditionally, the connected mode more complicated of its camshaft-bar linkage structure design, and the manner of execution of all parts of chamber body, installation trouble, stability is not high enough, and security performance is inadequate, waste material, cost is high, and the speed of opening and closing regulates very inconvenient; And installation floor spring must at ground borehole, for fitting up, rear installation floor spring is very inconvenient, wastes time and energy very much.
Utility model content
For solving the problem, the utility model provide a kind of structure simple, install without the need to ground borehole, built-in floor spring easy for installation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of built-in floor spring, comprises body, and the inner chamber of body slides and roller mount, connecting rod and piston are housed, and body is provided with camshaft, camshaft is fixed with cam; One end of described connecting rod is connected with roller mount, and the other end is connected with piston, and one end cover that connecting rod connects piston has spring, and itself and roller mount to be divided by dividing plate and be interposed between in different chambers by this spring; Camshaft is located at the side of connecting rod, and the cam of camshaft contacts with roller mount.
Furthermore, the two ends of described chamber body are closed by end cap.
Furthermore, described body bottom portion is also provided with base.
Furthermore, the bottom of described body is also provided with needle valve, and this needle valve is connected with the chamber of piston both sides respectively.
Described camshaft is arranged on body by bearing.
The beneficial effects of the utility model are: by the opening and closing of roller mount and camshaft control gate, and structure is simple, and installation and maintenance are easy, low cost of manufacture, can by the speed regulating described needle valve valve opening size to carry out the opening and closing of control gate, safety is high, good stability.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1 body, 2 roller mount, 3 camshafts, 4 connecting rods, 5 springs, 6 pistons, 7 end caps, 8 needle valves, 9 bases, 10 bearings.
Detailed description of the invention
Shown in Fig. 1, the built-in floor spring of one of the present utility model, comprises body 1, and the inner chamber of body 1 slides and roller mount 2, connecting rod 4 and piston 6 are housed, and body 1 is provided with camshaft 3, camshaft 3 is fixed with cam; One end of described connecting rod 4 is connected with roller mount 2, and the other end is connected with piston 6, and one end cover that connecting rod 4 connects piston 6 has spring 5, and itself and roller mount 2 points is interposed between in different chambers by dividing plate by this spring 5; Camshaft 3 is located at the side of connecting rod 4, and the cam of camshaft 3 contacts with roller mount 2.The two ends of body 1 inner chamber are closed by end cap 7.Base 9 is also provided with bottom body 1.Also be provided with needle valve 8 in the bottom of body 1, this needle valve 8 is connected with the chamber of piston 6 both sides respectively.Above-mentioned camshaft 3 is arranged on body 1 by bearing 10.
Operating principle of the present utility model: during door capable of being opened, roller mount 2 produces displacement backward under the effect of camshaft 3 overhead cam, and drives piston 6 also to move backward by connecting rod 4, is compressed by spring 5 simultaneously; When people or object are through later, when door closes, spring 5 resets, under the effect of spring 5 spring force, promote piston 6 and move forward, then drive roller mount 2 to move forward by connecting rod 4, actuating cam rotates, and camshaft 3 rotates, then being rotated by camshaft 3 makes door close.Wherein, the speed that door closes can pass through the size regulating needle valve 8 aperture, thus the closing velocity of control gate, reach desirable stability, safety.
Floor spring, when specifically installing, is first arranged on door by the utility model, by the floor installation corresponding with floor spring on the ground, like this without the need to borehole other on ground.
Above embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; those skilled in the art modify to the technical solution of the utility model or equivalent to replace, and all fall in protection domain that claims of the present utility model determine.
