Concealed floor spring
Technical field
The utility model relates to fittings for glass doors field, especially a kind of concealed floor spring of digging pit of exempting from.
Background technology
Floor spring is also a kind of hydraulic door closer, and only the device of its holddown spring is worm gear rather than rack-and-pinion.Because worm gear can forward and reversely rotate, so floor spring can be for the door of bidirectional opening, door closer can only be for the door of unidirectional unlatching.
Traditional floor spring is installed need to cut out the notch of by the sideline of the floor spring contour area of having retouched with angle grinding machine, then take the earth material in electric hammer or manual chisel excavation floor spring contour area, wherein can arrange in pairs or groups angle grinding machine, electric hammer, chisel Reusability, thin portion place chisel, relatively large material electric hammer, angle grinding machine can be used in position, sideline, and the degree of depth of the lower floor spring groove of amount can be put into geosyncline by floor spring body when approaching gauge simultaneously.As can be seen here, traditional floor spring installation procedure is complicated, and labour intensity is large, and floor spring is embedded in below ground, often, easily because meet aqueous corrosion, causes shorten application life, and installation and dismounting are all inconvenient, to people, bring many troubles.
Utility model content
The purpose of this utility model is to provide a kind of concealed floor spring of exempting to dig pit, and does not need to dig a hole into the earth floor spring is embedded in to the inside, and operation is simple, and installation and removal all easily, fast.
The utility model solves the technical scheme that its technical problem adopts: a kind of concealed floor spring, comprise for the floor spring main body at clamping glass door angle and coordinate the base rotating with floor spring main body, it is characterized in that: described floor spring main body lower end is provided with square that can movable debugging, in the middle of the base that is mated, be provided with axis hole, described base be also provided with for the fixing fixing hole in ground.
Described base comprises holder and axle bed, and axis hole is located in the middle of axle bed, and fixing hole is located at holder edge.
The groove that is provided with perforate in the middle of described holder, axle bed is placed in the groove of holder.
Described holder and axle bed are screwed.
Described floor spring main body upper end is provided with the grooved rail for placing glass door angle, and the side corresponding with grooved rail is provided with for coordinating the screwed hole at screw fixing glass door angle.
Described floor spring main body both sides and the upside of base be respectively provided with for the protection of valve jacket.
The concealed floor spring of the utility model is compared with the floor spring first having, structure is advantages of simple more, need to not dig on ground a hole floor spring is embedded in to the inside, reduced the amount of labour of installing, improved efficiency, effectively prevented the corrosion that easily causes below ground ponding owing to being embedded in, and installed and dismantle all very convenient, quick.

The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further described.Should be appreciated that embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of concealed floor spring, comprises for the floor spring main body (1) at clamping glass door angle and coordinates the base (2) rotating with floor spring main body.
See Fig. 2, floor spring main body (1) lower end is provided with square (3) that can movable debugging, base (2) comprises holder (4) and axle bed (5), in the middle of holder (4), be provided with the groove of perforate, axle bed (5) is placed in the groove of holder (4), and be screwed, be provided with axis hole (6) in the middle of axle bed (5), the edge of holder (4) be provided with for the fixing fixing hole (7) in ground.
Floor spring main body (1) upper end is provided with the grooved rail (8) for placing glass door angle, and the side corresponding with grooved rail (8) is provided with the screwed hole (9) for coordinating screw fixing glass door angle.
As shown in Figure 3, the upside of floor spring main body (1) both sides and base (2) be respectively provided with for the protection of valve jacket (10).
During installation, first in the place's perforate of glass door angle, according to the position of base fixing hole, hole on the ground again, utilize rivet to say that base fixes on the ground, square in floor spring main body is placed in the axis hole of base, utilize key screw glass door angle to be fixed in the grooved rail of the floor spring main body that Yu Men angle coordinates, at the valve jacket of mounting spring main body and base respectively, the floor spring that can complete glass door is installed.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, replace and improvement etc. on an equal basis, within all should dropping on protection domain of the present utility model.
