Abstract

The utility model discloses a cam of easy installation sets up in notebook's pivot, its include the disk form body, be located the body middle part with pivot interference fit's slot hole, be located at least one bellying on body side surface, the slot hole includes two parallel arrangement's locating surface and two arched curved surfaces, the locating surface with the curved surface meets the position and is provided with and dodges the groove, be provided with on the locating surface a plurality of along the chute that locating surface length direction extends, the chute with the angle that the body becomes is the acute angle, because the utility model discloses a plurality of chutes have been set up on the locating surface for can produce more elastic deformation when the locating surface receives pressure, it is more convenient when the installation.

Description

Cam of easy installation

Technical Field

The utility model relates to a notebook computer accessory field, especially a cam of easy installation.

Background

The opening and closing of the notebook computer are usually realized through a hinge area, and the existing hinge device is provided with cams, so that the notebook computer can provide different assistance or resistance when being opened and closed to different angles through the cooperation between the cams.

In order to ensure that the screen is not loosened, the cam and the hinge shaft need to be connected in an interference fit manner, but the cam and the hinge shaft need to slide, so that the cam and the hinge shaft are troublesome to mount, and a special pressing device is usually required.

Thus, there is a need for a cam that is easy to install.

Disclosure of Invention

The utility model aims at providing an easy cam of installing.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a cam of easy installation sets up in the pivot axle of notebook, its includes the disk-shaped body, is located the body middle part with pivot axle interference fit's slot hole, be located at least one bellying of body side surface, the slot hole includes two parallel arrangement's locating surface and two arched curved surfaces, the locating surface with the curved surface meets the position and is provided with and dodges the groove, be provided with a plurality of on the locating surface along the chute that locating surface length direction extended, the chute with the angle that the body becomes is the acute angle.

Preferably, the included angle between the chute and the body is 20-40 degrees.

Preferably, the number of the inclined grooves is 4-6.

Preferably, the inclined grooves are uniformly distributed on the positioning surface.

Preferably, the area of the opening of the inclined groove accounts for 30% -50% of the area of the positioning surface.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

because the utility model discloses a plurality of chutes have been set up on the locating surface for can produce more elastic deformation when the locating surface receives pressure, it is more convenient when the installation.

Drawings

FIG. 1 is a perspective view of the present embodiment;

fig. 2 is a partially enlarged schematic view of fig. 1.

In the above drawings: 1. a body; 2. a boss portion; 3. positioning the surface; 4. a curved surface; 5. an avoidance groove; 6. a chute.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

referring to fig. 1, an easily-installed cam is arranged on a pivot shaft of a notebook computer and comprises a disk-shaped body 1, a long hole which is arranged in the middle of the body 1 and is in interference fit with the pivot shaft, and at least one protruding portion 2 which is arranged on one side surface of the body 1, wherein the long hole comprises two positioning surfaces 3 which are arranged in parallel and two arched curved surfaces 4, a avoiding groove 5 is arranged at the connecting position of the positioning surfaces 3 and the curved surfaces 4, a plurality of inclined grooves 6 which extend along the length direction of the positioning surfaces 3 are arranged on the positioning surfaces 3, and the angle formed by the inclined grooves 6 and the body 1 is an acute angle.

Specifically, the included angle between the chute 6 and the body 1 is 20-40 degrees. The number of the inclined grooves 6 is 4, and the inclined grooves 6 are uniformly distributed on the positioning surface 3.

In this embodiment, the area of the opening of the chute 6 occupies 30-50% of the area of the positioning surface 3.

because the utility model discloses a plurality of chutes 6 have been set up on locating surface 3 for locating surface 3 can produce more elastic deformation when receiving pressure, and it is more convenient when the installation.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
