Summary of the invention

The utility model purpose provides a kind of hinge means, its processing, easy to assembly, and fabricating cost is low, and position structure is simple, has reduced the assembling tolerance, has improved process rate, and locating effect is reliable and stable.

The technical solution of the utility model is: a kind of hinge means, the fixed base that comprises pivot, fixed pivot axi, and the spoon rack that can pivot, described spoon rack comprises fixing part and the bunching ring that is set on the pivot, described fixed base one side is provided with and the sheathed fixing axle sleeve of pivot, described axle sleeve is protruding the fixed base locator protrusions, described fixing part is axial along being extended with the spoon rack locator protrusions with respect to the fixed base locator protrusions, and the side of described fixed base locator protrusions and spoon rack locator protrusions is oppositely arranged.

The further technological scheme of the utility model is: a kind of hinge means, the fixed base that comprises pivot, fixed pivot axi, and the spoon rack that can pivot, described spoon rack comprises fixing part and the bunching ring that is set on the pivot, described fixed base one side is provided with and the sheathed fixing axle sleeve of pivot, described axle sleeve is protruding the fixed base locator protrusions, described fixing part is axial along being extended with the spoon rack locator protrusions with respect to the fixed base locator protrusions, and the side of described fixed base locator protrusions and spoon rack locator protrusions is oppositely arranged; Described fixed base locator protrusions can be along the axially extended flange of axle sleeve, also can be a boss that radially extends along axle sleeve; The fixing end of described pivot and axle sleeve is provided with the friction line.

The utility model advantage is:

1. the utility model hinge structure only comprises pivot, fixed base and three parts of spoon rack, and is simple and compact for structure.

2. pivot of the present utility model is easy to make, and can reduce fabricating cost greatly.

3. the utility model utilizes the axle sleeve on the fixed base and the fixing part of spoon rack directly to locate, and has reduced the assembly precision requirement, has improved process rate.

4. the utility model locating effect is reliable and stable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the utility model one embodiment's an assembling perspective view;

Fig. 2 is the blast perspective view of Fig. 1;

Fig. 3 is another embodiment's of the utility model an assembling perspective view;

Fig. 4 is the blast perspective view of Fig. 3.

Wherein: 1, pivot; 2, fixed base; 3, spoon rack; 4, fixing part; 5, bunching ring; 6, axle sleeve; 7, flange; 8, boss; 9, spoon rack locator protrusions; 10, friction line; 11, mounting hole.

Embodiment

Embodiment 1: Fig. 1, Figure 2 shows that a kind of specific embodiment of the present utility model, this embodiment comprises the fixed base 2 of pivot 1, fixed pivot axi 1 and the spoon rack 3 that can rotate around pivot 1, fixed base 2 is fixed with the notebook computer body, described spoon rack 3 comprises fixing part 4 and two bunching rings 5 that are set on the pivot 1, and the opening direction of two bunching rings 5 is opposite, fixing part 4 is provided with mounting hole 11 simultaneously, by mounting hole 11 directly and the notebook computer screen fix, make spoon rack 3 have the effect of bolster simultaneously concurrently.Described fixed base 2 one sides are provided with and pivot 1 sheathed fixing axle sleeve 6, described axle sleeve 6 and fixing part 4 opposing end faces are protruding vertically respectively flange 7 and spoon rack locator protrusions 9, the side of described flange 7 and spoon rack locator protrusions 9 is oppositely arranged, and promptly flange 7 is positioned at the relative recess of the other side mutually with spoon rack locator protrusions 9.When spoon rack 3 rotates with respect to pivot 1, flange 7 and spoon rack locator protrusions 9 relatively rotate, when the sense of rotation side offseted, then rotation was placed restrictions in the location, thereby makes the body of notebook computer and screen can only be opened to several angle up to flange 7 and spoon rack locator protrusions 9.

Described pivot 1 is provided with friction line 10 with the end that axle sleeve 6 is fixed, some the teeth that this friction line 10 is provided with for a circle parallel to an axis of being located at pivot 1 surface, friction line 10 cooperates with axle sleeve 6 inwalls, increases frictional force, makes pivot 1 and the fixing of axle sleeve 6 stablize firmly more.

Embodiment 2: Fig. 3, Fig. 4 are another specific embodiment of the present utility model, and this embodiment comprises the fixed base 2 of pivot 1, fixed pivot axi 1 and the spoon rack 3 that can rotate around pivot 1; The structure of described pivot 1 and spoon rack 3 is identical with embodiment 1.Radially extend a boss 8 along axle sleeve 6 and be this embodiment's fixed base locator protrusions; Identical with embodiment 1, described pivot 1 inserts in the axle sleeve 6, axially with circumferentially all be fixed, friction line 10 has increased the friction between pivot 1 and axle sleeve 6 inwalls, thus minimizing is repeatedly rotated the possibility that causes matching loose between pivot 1 and the axle sleeve 6 because of hinge means; As shown in Figure 4, pivot 1 stretches in the spoon rack 3, and the spoon rack locator protrusions 9 on the spoon rack 3 is kept out restriction mutually with the boss 8 on the fixed base, plays the effect of location equally.

The utility model component are few, processing, easy to assembly, and fabricating cost is low, and position structure is simple, has reduced the assembling tolerance, has improved process rate, and locating effect is reliable and stable.
