Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention.
The unidirectional buffer rotating shaft of the first embodiment comprises a rotating shaft 1 which is cylindrical as a whole, wherein a first buffer surface 12 and a second buffer surface 13 are respectively formed by the recess of the rotating shaft 1; the first buffer surface 12 is perpendicular to the second buffer surface 13 and is offset from the second buffer surface 13 (i.e., a projection of the first buffer surface 12 on a plane passing through the axis of the rotating shaft 1, a projection of the second buffer surface 13 on a plane passing through the axis of the rotating shaft 1, and a portion where the two do not overlap).
The glass door clamping seat of the first embodiment comprises the one-way buffering rotating shaft, and further comprises a clamping seat assembly 2 and a base 3.
The holder assembly 2 includes a holder main body 21, and the holder main body 21 is provided with a first elastic member 22 and a second elastic member 23. Usually, one end of the first elastic element 22 and one end of the second elastic element 23 respectively abut against the inner wall of the holder main body 21; the other end of the first elastic member 22 and the other end of the second elastic member 23 are abutted against the rotating shaft 1. Generally, the first elastic member 22 and the second elastic member 23 are a spring providing an elastic force and a gas spring providing a damping force, respectively.
The rotating shaft 1 is hinged to the holder body 21, and two ends (i.e. the mounting end 119) are respectively and fixedly connected to the base 3. Generally, the means for fixedly connecting the shaft 1 and the base 3 is the same as that disclosed in CN 208456354U.
The working principle is as follows: before use, the base 3 is fixed on a fixture, such as a wall or the like; and then fixedly attaching (by conventional fixing means) a glass door or the like to the holder assembly 2.
When the glass door is used, the glass door (the attached drawing is not shown) is pushed, the glass door drives the holder component 2 to rotate, and in the process that the holder component 2 rotates and the rotating shaft 1 rotates around the axis of the rotating shaft 1, the first elastic piece 22 and the second elastic piece 23 respectively abut against the first buffering surface 12 and the second buffering surface 13 to respectively provide elastic force and damping force, so that the door can be opened with less force (due to the elastic force of the spring) and closed with safety (due to the damping force, the door can be closed slowly and cannot quickly impact on glass).
When the first buffer surface 12 and the second buffer surface 13 are machined, only the first buffer surface 12 is machined on the cylindrical blank by adopting the side surface of an end mill (not shown in the drawing), then the height of the end mill is adjusted, and the second buffer surface 13 is machined by adopting the bottom end surface of the end mill; namely, the one-way buffering rotating shaft of the first embodiment is relatively simple to process and manufacture and low in cost.
Preferably, the radius of the rotating shaft 1 is a rotating shaft radius R, and the depth of the buffer surface (not shown in the drawings, i.e. the first buffer surface 12 and the second buffer surface 13) is a buffer surface depth a, so that the buffer surface depth a is smaller than the rotating shaft radius R.
Preferably, the ratio of the depth a of the relief surface to the radius R of the shaft is one-third to two-thirds. The strength of the rotating shaft 1 can be ensured.
Preferably, the cushioning surface depth a of the first cushioning surface 12 is equal to the cushioning surface depth a of the second cushioning surface 13.
Preferably, the transition section 14 is formed by rounding off the joint of the first buffer surface 12 and the cylindrical surface of the rotating shaft 1, the joint of the second buffer surface 13 and the cylindrical surface of the rotating shaft 1, and as shown in fig. 5, the axis of the transition section 14 is located on the orthogonal plane of the rotating shaft 1 when viewed along the axis of the rotating shaft 1; the orthogonal planes of the rotating shaft 1 are a plane passing through the axis of the rotating shaft 1 and parallel to the first buffer surface 12, and a plane passing through the axis of the rotating shaft 1 and parallel to the second buffer surface 13. When the glass door (not shown in the drawing) is pushed and the glass door drives the holder component 2 to rotate, and when the holder component 2 rotates and the rotating shaft 1 starts to rotate around the axis of the rotating shaft 1, the force application member (not shown in the drawing, namely the first elastic member 22 and the second elastic member 23) is tangent to the transition section 14 and is guided by the transition section 14, so that the holder component 2 can rotate smoothly.
Preferably, the radius of the rotating shaft 1, the radius of the first elastic member 22, and the radius of the second elastic member 23 are all equal. The contact area of the force application part and the rotating shaft 1 can be ensured, so that the clamping seat component 2 rotates smoothly.
In the pulley-type shaft of the second embodiment, the shaft 1 omits the shaft reinforcing section 118.
Accordingly, in the second embodiment of the glass door clip, the clip base body 21 omits the clip base reinforcement section 218. The width of the cartridge assembly 2 can be reduced, which is advantageous for cost saving and miniaturization.
It will be understood that the terms "central," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for the convenience and simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered limiting of the scope of the present invention.
