Description

Rotating shaft

Technical Field

The utility model relates to a connecting device between product parts especially relates to a pivot.

Background

The traditional product (such as a cosmetic mirror and the like) swinging shaft does not have a limiting locking function, when the product does not need to swing or is carried about, the product still can swing continuously under the action of external force, the swinging support is easy to loosen or damage, and meanwhile, other objects are easy to hook due to the fact that the swinging support is exposed. Therefore, it is an urgent need for those skilled in the art to develop a rotating shaft.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rotary shaft to solve the above insufficiency.

The above object of the present invention is achieved by the following technical solutions: a rotating shaft comprises a shell, a positioning shaft core, a telescopic sleeve and a swinging support, wherein the swinging support comprises a fixed support and a movable support (fixed on a product main body, such as a mirror body of a cosmetic mirror), the fixed support is in an 'Jiong' shape, two sides of the fixed support are connected with the fixed movable support through the rotating shaft, the movable support is in an 'L' shape, and a fixing hole is formed in the end face of the middle part of the fixed support;

the telescopic sleeve is tubular, one end of the telescopic sleeve is provided with a threaded end head, and the telescopic sleeve is fixed at a fixing hole of the fixing support through a nut; the side wall of the telescopic sleeve is provided with a spiral guide groove which is spirally arranged on the outer wall of the telescopic sleeve, and the two ends of the spiral guide groove are provided with a front limit groove and a rear limit groove;

the positioning shaft core is inserted into the telescopic sleeve, and a sliding positioning pin clamped into the spiral guide groove is fixed on the side wall of the front end of the positioning shaft core;

the rear end of the positioning shaft core is provided with a fixed disc, the fixed disc is provided with a screw hole, and the fixed disc is fixed on the bottom surface of the inner cavity of the shell cover through a screw.

The utility model discloses a theory of operation: the product fixed on the movable support through the rotary connection drives the telescopic sleeve, the telescopic sleeve moves and stretches under the matching action of the spiral guide groove and the sliding positioning pin, and the telescopic sleeve stops when the sliding positioning pin reaches the front limiting groove or the rear limiting groove of the spiral guide groove. When the sliding positioning pin is positioned in the front limiting groove of the spiral guide groove, the shell cover integrally covers the swinging support, the swinging support is limited in the shell cover, so that the swinging support cannot swing.

Compared with the prior art, the utility model the advantage be: the utility model discloses a whether flexible product of controlling can sway, and when contracting, can ensure to sway the support and can not receive the exogenic action to sway at will, play the effect that the protection swayd the support, simultaneously, also can prevent to sway the support and collude other article.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, a rotating shaft comprises a housing 1, a positioning shaft core 2, a telescopic tube 3 and a swing bracket 4, wherein the swing bracket 4 comprises a fixed bracket 4-1 and a movable bracket 4-2 (fixed on a product main body, such as a mirror body of a cosmetic mirror), the fixed bracket 4-1 is shaped like Jiong, two sides of the fixed bracket 4-1 are connected with the fixed movable bracket 4-2 through the rotating shaft 4-3, the movable bracket 4-2 is shaped like an L, and a fixing hole 4-4 is arranged on the end surface of the middle part of the fixed bracket 4-1;

the telescopic sleeve 3 is tubular, one end of the telescopic sleeve is provided with a threaded end 3-1, and the telescopic sleeve is fixed at a fixing hole 4-4 of the fixing bracket 4-1 through a nut 5; the side wall of the telescopic sleeve 3 is provided with a spiral guide groove 3-2, the spiral guide groove 3-2 is spirally wound on the outer wall of the telescopic sleeve 3, and the two ends of the spiral guide groove 3-2 are provided with a front limiting groove 3-3 and a rear limiting groove 3-4;

the positioning shaft core 2 is inserted into the telescopic sleeve 3, and the side wall of the front end of the positioning shaft core 2 is fixedly provided with a sliding positioning pin 2-1 clamped into the spiral guide groove 3-2;

the rear end of the positioning shaft core 2 is provided with a fixed disc 2-2, the fixed disc 2-2 is provided with a screw hole 2-3, and the fixed disc is fixed on the bottom surface of the inner cavity of the shell cover 1 through a screw.

The utility model discloses a theory of operation: the product which is connected and fixed on the movable support 4-2 in a rotating mode drives the telescopic sleeve 3, the telescopic sleeve 3 moves and stretches under the matching effect of the spiral guide groove 3-2 and the sliding positioning pin 2-1, and the telescopic sleeve stops when the sliding positioning pin 2-1 reaches the front limiting groove 3-3 or the rear limiting groove 3-4 of the spiral guide groove 3-2. When the sliding positioning pin 2-1 is positioned in the front limiting groove 3-3 of the spiral guide groove 3-2, the shell cover 1 integrally covers the swing support 4, the swing support 4 is limited in the shell cover 1, so that the swing support cannot swing, and when the sliding positioning pin 2-1 is positioned in the rear limiting groove 3-4 of the spiral guide groove 3-2, the swing support 4 is separated from the shell cover 1 and is exposed out of the shell cover 1, so that the swing function can be realized.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
