Degree.
Embodiment 3
On the basis of embodiment 1 or embodiment 2, present embodiments provide and a kind of realize that the two-way of Fast Installation closes automatically
The equipment of door.
The ditch sheave of the equipment as shown in figure 9, the ditch sheave 123, including：Groove 1231 and through hole 1232.
The groove 1231 is the axis direction parallel to the ditch sheave 123 positioned at the outer of ditch sheave 123
Groove.
The through hole 1232 is circular hole at the center of the axis direction of the ditch sheave, the through hole 1232 it is straight
Footpath is equal to the diameter of the upper shaft lever 122.
Specifically, the quantity of the groove 1231 is four, and this four grooves 1231 are distributed in the outer of ditch sheave 123
Edge, and the central angle of two adjacent grooves 1231 is 90 °, the through hole 1232 is located at the axle center of the ditch sheave 123, institute
Through hole 1232 is stated to be used to pass through upper shaft lever 122.Its adjacent groove 1231 is pointed to by the bottom land of a groove 1231
Groove along between the ditch sheave 123 outer and the distance of the axis of the ditch sheave 123 gradually increase.
Due to design is optimized at the outer of the ditch sheave 123, i.e.,：The through hole 1232 is used to make upper shaft lever
122 pass through.The ditch sheave of the groove of its adjacent groove 1231 between is pointed to by the bottom land of a groove 1231
123 outer and the distance of the axis of the ditch sheave 123 gradually increase so that door is at wide-angle opening (30~75 °)
Under, the steel ball 15 also can make the steel ball 15 be pushed back the initial groove under the elastic force effect of the spring 14
In 1231, so as to realize the automatic closing of door；To make door be in opening, as long as the opening angle of door is slightly larger than
90 °, the steel ball 15 just can be such that the steel ball 15 is pushed back and its initial ditch under the elastic force effect of the spring 14
In the adjacent groove 1231 of groove, so that door is in opening.To realize that door is closed from fully open state, only
Need to rotate backward door, the upper shaft lever 122 drives the ditch sheave 123 to rotate backward, and the ditch sheave 123 causes steel ball institute
State 15 to roll along the outer of the ditch sheave 123, and then compress the spring 14, until the steel ball 15 revert to initial shape
In the groove 1231 of state, that is, complete closing of the door by fully open state.
The present embodiment can not only reach the technique effect of embodiment 1 or embodiment 2, and also increasing door can close automatically
Angle, realize the automatic door-closing under wide-angle (30~75 °) state.
Compared with prior art, the equipment of the two-way automatic door-closing of the present utility model for realizing Fast Installation, realize as
Under beneficial effect：
(1) equipment of the two-way automatic door-closing provided by the utility model for realizing Fast Installation, by upper shaft assembly and lower axle
The function of component is redistributed, and lower shaft component is only had the function of bearing a weight and rotation, so as to reduce lower axle group
The thickness of part, its thickness is set to be less than the thickness of floor and floor tile so that lower shaft component need not carry out pre-buried or right in installation process
Cement flooring is cut, and simplifies the installation of two-way automatic door-closing, improves installation rate；
(2) by designing supporting door pocket, bolt is only needed to can be achieved the connection of upper shaft assembly and door pocket, axle group in simplification
The installation difficulty of part, further improves installation rate；
(3) ditch sheave is optimized into design so that the groove of groove is directed towards between by the bottom land of a groove
The outer of ditch sheave and the distance of axis gradually increase, and can realize the automatic door-closing under wide-angle state；
(4) shaft assembly is using power transmission of the cooperation of jackscrew-spring-steel ball as automatic door-closing equipment, phase on
The hydraulic way used for floor spring in the prior art, had both facilitated each part (jackscrew/spring/steel ball) of power transmission
Replacing, structure is also more simple；
(5) lower bearing uses rolling bearing, because the length in the axial direction of rolling bearing is smaller, can further reduce
The thickness of lower shaft component, and rolling bearing is more laborsaving in enabling or optical gate；
(6) because the head of upper shaft lever is kidney-shaped convex, it is easy to the head of upper shaft lever and door to form firm clamping, pacifies
Dress is more laborsaving, convenient.
Certainly, implement any product of the present utility model must not specific needs reach all the above technology effect simultaneously
Fruit.
Although some specific embodiments of the present utility model are described in detail by example, this area
It is to be understood by the skilled artisans that example above merely to illustrate, rather than in order to limit the scope of the utility model.This
Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case of, to above example
