Abstract
The utility model discloses a hinge device which comprises a mandrel, a permanent seat fixed with the mandrel, and a tubular spring frame rotating around the mandrel, wherein the tubular spring frame comprises a fixed part and a tightening ring sleeved on the mandrel, one side of the permanent seat is provided with a mandrel housing fixed with the mandrel by a sleeving way, the end faces of the mandrel housing opposite to the tightening ring respectively outwards extend to form a permanent seat positioning lug and a tubular spring frame positioning lug along the axial direction, and the sides of the permanent seat positioning lug and the tubular spring frame positioning lug are arranged oppositely. The utility model has the advantages of fewer parts, convenient processing and assembly, low manufacture cost, simple positioning structure, assembly tolerance reduction, procedure yield improvement and reliable and stable positioning effect.
Description
Technical field
The utility model relates to a kind of hinge means.
Background technique
Notebook computer has screen and body, and the both sides between screen and body can be provided with hinge means, makes between screen and the body folding relatively and make screen can be switched to suitable angle to use for the user.Pipe spring formula linkage is a kind of component hinge meanss few, easy to assembly, it is arranged with spoon rack on mandrel, spoon rack comprises the bunching ring that is rolled into tubular, and the fixing part that radially extends to form of bunching ring one end, the bunching ring the other end and fixing part form opening, bunching ring is set in the outer and snap close mandrel of mandrel, and mandrel and bunching ring are interfered generation torsion mutually.In the prior art, generally can be provided with axial projections at an end of spoon rack bunching ring, then be provided with a radial projection with the corresponding position of this axial projections on the mandrel, when mandrel and bunching ring relatively rotate, radial projection and the axial projections on the bunching ring on the mandrel can be met, thereby stop further rotation, and then define the folding angle between notebook screen and the body.
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 mandrel, fixed central spindle, and can be around the spoon rack of mandrel rotation, described spoon rack comprises fixing part and the bunching ring that is set on the mandrel, described fixed base one side is provided with and the sheathed fixing axle sleeve of mandrel, described axle sleeve and bunching ring opposing end faces be protruding vertically respectively fixed base locator protrusions and spoon rack 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 mandrel, fixed central spindle, and can be around the spoon rack of mandrel rotation, described spoon rack comprises fixing part and the bunching ring that is set on the mandrel, described fixed base one side is provided with and the sheathed fixing axle sleeve of mandrel, described axle sleeve and bunching ring opposing end faces be protruding vertically respectively fixed base locator protrusions and spoon rack locator protrusions, and the side of described fixed base locator protrusions and spoon rack locator protrusions is oppositely arranged; The fixing end of described mandrel and axle sleeve is provided with the friction line.
The utility model advantage is:
1. the utility model hinge structure only comprises mandrel, fixed base and three parts of spoon rack, and is simple and compact for structure.
2. mandrel of the present utility model is easy to make, and can reduce fabricating cost greatly.
3. the utility model utilizes an end face of bunching ring on the end face of fixed base Upper shaft sleeve and the 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
Fig. 1 is the utility model embodiment's an assembling perspective view;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the utility model embodiment's a blast perspective view.
Wherein: 1 mandrel; 2 fixed bases; 3 spoon racks; 4 bunching rings; 5 fixing parts; 6 axle sleeves; 7 fixed base locator protrusionss; 8 spoon rack locator protrusionss; 9 friction lines; 10 mounting holes.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of hinge means, comprise the fixed base 2 of mandrel 1, fixed central spindle 1 and the spoon rack 3 that can rotate around mandrel 1, fixed base 2 is fixed with the notebook computer body, described spoon rack 3 comprises fixing part 5 and the bunching ring 4 that is set on the mandrel 1, a fixing part 5 is provided with two bunching rings 4 in the present embodiment, and the opening direction of two bunching rings 4 is opposite, fixing part 5 is provided with mounting hole 10 simultaneously, by mounting hole 10 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 mandrel 1 sheathed fixing axle sleeve 6, described axle sleeve 6 and bunching ring 4 opposing end faces are protruding vertically respectively fixed base locator protrusions 7 and spoon rack locator protrusions 8, the side of described fixed base locator protrusions 7 and spoon rack locator protrusions 8 is oppositely arranged, and promptly fixed base locator protrusions 7 is positioned at the other side's recess relative with projection mutually with spoon rack locator protrusions 8.When spoon rack 3 rotates with respect to mandrel 1, fixed base locator protrusions 7 and spoon rack locator protrusions 8 relatively rotate, up to fixed base locator protrusions 7 and spoon rack locator protrusions 8 when the sense of rotation side offsets, then rotation is placed restrictions in the location, thereby makes the body of notebook computer and screen can only be opened to several angle.As shown in Figure 2, the circumferential radian of two locator protrusionss all is approximately the quadrant arc.
Described mandrel 1 is provided with friction line 9 with the end that axle sleeve 6 is fixed, some the teeth that this friction line 9 is provided with for a circle parallel to an axis of being located at mandrel 1 surface, friction line 9 cooperates with axle sleeve 6 inwalls, increases frictional force, makes mandrel 1 and the fixing of axle sleeve 6 stablize firmly more.
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.
