Abstract

The utility model discloses a damp rotation shaft, which is composed of a shaft housing and a rotation shaft, wherein both ends of the shaft housing are respectively provided with a longitudinal shaft hole, the rotation shaft is composed of a pin shaft and a shaft cap which is fixedly connected on one end of the pin shaft, the pin shaft which is arranged on the rotation shaft is inserted into a shaft hole of the shaft housing in an interference fit mode, and the inserting end of the shaft housing is provided with a longitudinal elongated slot which is traversed through the central line of the shaft pin. Since the rotation shaft of the utility model is only composed of two components, namely the shaft housing and the rotation shaft and the like, thereby the components are less, the structure is simple, when in assembly, only the pin shaft portion of the rotation shaft is inserted into the shaft housing, thereby the assembly is very convenient.

Description

Damping rotation shaft

Technical field

The utility model relates to a kind of hinge, particularly relates to a kind of Damping rotation shaft.

Background technology

Traditional hinge means mostly is to be used for installing of door, window, as long as realize the flexible connection between door-plate and doorframe, window and the window frame.The cupboard door that is used for furniture that has also only needs to realize the location opening and close.This hinge of commonly using can't be implemented in the function of location, optional position.For this reason, the dealer designs the various hinges that can stop at an arbitrary position, and the key structure of this hinge is exactly rotating shaft.The existing pivot structure that can stop at an arbitrary position is all comparatively complicated.

The utility model content

The purpose of this utility model is to provide a kind of Damping rotation shaft simple in structure, easy for installation.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of Damping rotation shaft, and it is made up of axle sleeve and rotating shaft; Described axle sleeve has a vertical axis hole; Described rotating shaft is made up of bearing pin and the axle cap that is connected bearing pin one end, and described bearing pin inserts in the mode of interference fit in the axis hole of axle sleeve, and the insertion end of described bearing pin offers long and narrow groove.

The long and narrow groove of the insertion end of described bearing pin is the vertical long and narrow groove that passes the pivot pin center line.

A vertical axis hole is offered at the two ends of described axle sleeve respectively, and vertical axis hole at these two ends has same axial line, can allow a rotating shaft insert in the mode of interference fit respectively.

Described sleeve outer surface longitudinally symmetrical parallel offers and rises as high as the banks.

The axle cap external surface of described rotating shaft longitudinally symmetrical parallel offers and rises as high as the banks.

After adopting such scheme, because the utility model only is made up of two members such as axle sleeve and rotating shafts, parts are few, simple in structure; During installation,, install very convenient as long as the bearing pin portion of rotating shaft is inserted axle sleeve.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is a kind of Damping rotation shaft, and it is made up of axle sleeve 1 and rotating shaft 2.

A vertical axis hole 11 is offered at the two ends of described axle sleeve 1 respectively, and vertical axis hole 11 at these two ends has same axial line.

Described rotating shaft 2 is made up of bearing pin 21 and the axle cap 22 that is connected bearing pin 21 1 ends, and bearing pin 21 and axle cap 22 are generally integral member.Described rotating shaft 2 has two, and the bearing pin 21 in two rotating shafts 2 inserts in the axis hole 11 at axle sleeve 1 two ends in the mode of interference fit respectively.The insertion end of described rotating shaft 2 upper pins 21 offers long and narrow groove 211, this long and narrow groove 211 is for passing the vertical long and narrow groove 211 of pivot pin 21 center lines, because bearing pin 21 insertion ends that are split into two can be to internal strain, the bearing pin 21 in the rotating shaft 2 is easy to insert in the axis hole 11 of axle sleeve 1.

For the ease of the flap (not shown) is installed, axle sleeve 1 external surface longitudinally symmetrical parallel offer 12 (as shown in Figure 4) of rising as high as the banks.Axle cap 22 external surfaces of rotating shaft 2 longitudinally symmetrical parallel offer 221 (as shown in Figure 5) of rising as high as the banks.

During assembling (as shown in Figure 3), as long as rotating shaft 2 is inserted in the axis hole 11 at axle sleeve 1 two ends in the mode of interference fit.
