Abstract

The utility model relates to a hinge used on a door or a window, in particular to a noiseproof hinge, which comprises a lower hinge plate, an upper hinge plate and a hinge shaft; wherein the lower hinge plate and the upper hinge plate can be rotated around the hinge shaft which is a plain shaft; and the lower end of the hinge shaft is provided with a socket. The lower hinge plate and the upper hinge plate are provided with earcaps which are provided with chambers, and a steel ball is arranged in the chamber of the lower hinge plate. In the process of mounting, the lower hinge plate is first fixed, the hinge shaft is put into the earcap of the lower hinge plate, and the upper hinge plate is mounted on the door or the window, and is sleeved on the hinge shaft; since the ball is arranged in the chamber of the lower hinge plate and the lower end of the hinge shaft is provided with the socket, the socket of the hinge shaft faces the steel ball; and since the prior surface contact is changed into the present linear contact when the scheme is adopted to support the hinge shaft, noise is reduced, and lubricant can be added in the chamber of the lower hinge plate to prevent rust.

Description

A kind of noiseproof loose-leaf

Technical field

The utility model relates to the loose-leaf that uses on a kind of door and window, particularly a kind of noiseproof loose-leaf.

Background technology

Used traditional loose-leaf comprises following movable sheet 1, goes up movable sheet 2 and hinge axis 5 on the door and window as shown in Figure 1, following loose-leaf 1 and last loose-leaf 2 can rotate around hinge axis 5, hinge axis 5 is provided with the ring-type shaft shoulder 3, has ear muff 4 on following movable sheet 1 and the last movable sheet 2, when door and window is installed, to play loose-leaf 1 fixing earlier, hinge axis 5 is put into down in the ear muff 4 of loose-leaf 1, on door and window, load onto loose-leaf 2, to go up loose-leaf 2 is inserted in hinge axis 5 and gets final product, though this kind loose-leaf simple and wear well, this loose-leaf can produce noise with the shaft shoulder 3 contact positions of going up movable sheet 2 and ring-type long afterwards.

The utility model content

The technical problems to be solved in the utility model provides a kind of noiseproof loose-leaf that can prevent that hinge axis from getting rusty and not produce noise.

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of noiseproof loose-leaf comprises down movable sheet, goes up movable sheet and hinge axis, and described loose-leaf down and last loose-leaf can rotate around hinge axis, and it is characterized in that: described hinge axis is an optical axis, and the lower end of described hinge axis is provided with a groove.

Below be to further improvement in the technical proposal:

Have ear muff on described movable sheet down and the last movable sheet, have chamber in the described ear muff, be provided with steel ball in the chamber of described movable sheet down.

Adopt technique scheme, during installation, to play loose-leaf to fix earlier, hinge axis be put into down in the ear muff of loose-leaf, on door and window, load onto loose-leaf, to go up loose-leaf is inserted in hinge axis and gets final product, because be provided with steel ball in the chamber of following movable sheet, the lower end of described hinge axis is provided with a groove, the groove of hinge axis is over against steel ball, adopt such scheme that the support of hinge axis is changed into present line contact having reduced noise by original face contact, in the chamber of following movable sheet, can add lubrication oil and prevent to get rusty.

Come the technical solution of the utility model is further described below in conjunction with drawings and Examples:

Description of drawings

Accompanying drawing 1 is the structural representation of traditional loose-leaf;

Accompanying drawing 2 is the structural representation of noiseproof loose-leaf among the utility model embodiment.

Movable sheet, the last movable sheet of 2-, 4-ear muff, 6-hinge axis, 7-steel ball, 8-lubrication oil, 9-groove, 10-chamber under the 1-.

The specific embodiment

Embodiment, as shown in Figure 2, a kind of noiseproof loose-leaf comprises down movable sheet 1, goes up movable sheet 2 and hinge axis 6, and described loose-leaf 1 down and last loose-leaf 2 can rotate around hinge axis 6, described hinge axis 6 is an optical axis, the lower end of described hinge axis 6 is provided with a groove 9, has ear muff 4 on described movable sheet down and the last movable sheet 2, has chamber 10 in the described ear muff 4, can add lubrication oil 8 in the described chamber 10, be provided with steel ball 7 in the chamber 10 of described movable sheet 1 down.

During installation, to play loose-leaf 1 fixing earlier, hinge axis 6 is put into down in the ear muff 4 of loose-leaf 1, on door and window, load onto loose-leaf 2, to go up loose-leaf 2 is inserted in hinge axis 6 and gets final product, owing to be provided with steel ball in the chamber 10 of following movable sheet 1, the lower end of described hinge axis 6 is provided with a groove 9, the groove 9 of hinge axis is over against steel ball 7, the utility model changes present line contact to the support of hinge axis into by original face contact, reduced contact area, reduced noise, in the chamber 10 of following movable sheet 2, can add lubrication oil 8 and prevent to rotate ineffective loose-leaf and get rusty.
