Abstract

The utility model relates to a pivot device. An open taper axle sleeve with hollow form is formed at one end of the main shaft rod. Screws are formed at the exterior margin and a tightening ring is sleeved and assembled on the outboard of the axle sleeve. An intra bevel is formed at one end of the inboard of the tightening ring and screws matched with the exterior margin screw of the axle sleeve are arranged on the other end. An oil guiding groove is equipped on the exterior margin of the assistant shaft rod that can be directly penetrated or assembled in the axle sleeve of the main shaft rod. When pivoting the tightness between the main and the assistant shaft rod is adjusted according to the tightening ring adjusting the compression degree of the axle sleeve inner face to the assistant shaft rod. The pivot device of the utility model is convenient to assemble and the production cost can be reduced.

Description

Pivot device

The utility model relates to a kind of pivot device, relates in particular to a kind of pivot device that can be used on the notebook computer.

Notebook computer is because volume is small and exquisite and easy to carry, structure by this class notebook computer, it is articulated with pivot device between LCD and main frame, this pivot device will provide a function that articulates on the one hand, on the other hand then must be when opening, can stagnate in position, traditional pivot is the axle sleeve that forms in the spindle rod end and is located in sheathed assembling one beam barrel between paraxial rod in the axle sleeve, this beam barrel generally is to make with macromolecular material, be to adopt friction tight mode to assemble when assembling, that is after the pivot device assembling of traditional structure is finished, it all has identical elasticity, as the specification difference of the notebook computer that cooperates, and have the LCD of Different Weight, then inevitable its pivot device the supporting effect that can provide inequality.

Analyze as can be known with regard to actual state, pivot device must provide certain tightness degree, can be when LCD be flared to suitable angle, a positioning action is provided, when using with traditional structure, because its elasticity can't be adjusted, so when too loose, can't provide positioning action, being difficult for when then causing unlatching and closure when too tight, obviously the structure of traditional type fails to provide appropriate practicality, again, after the long-term use of notebook computer, the beam barrel that its macromolecular material is made will inevitably strengthen the gap because of wearing and tearing, so promptly can make its pivot device become loose and can't appropriately locate, and this more causes the greatest inconvenience of user.

The inventor proposed a kind of pivot device of disclosed improvement in No. the 83212590, the novel patent in Taiwan, but this pivot device still can further improve aspect structure and the cost, and more simplified with inexpensive.

The purpose of this utility model is: a kind of pivot device is provided, and its structure is simplified and easy to assembly, can reduce production costs, and have the effect that can adjust the elasticity when pivoting between major and minor axostylus axostyle concurrently.

The technical solution of the utility model is to provide a kind of pivot device, and it is made of spindle rod, paraxial rod and packing cover, and its characteristics are:

Spindle rod one end is for carving the fixed part of flat, on this fixed part, be formed with fixed orifice, the other end of spindle rod then forms the axle sleeve of a hollow, form oblique tapering outside at this axle sleeve front end place, its medial extremity is then horizontal, again, is formed with opening on the axle sleeve, and be formed with screw thread in the axle sleeve outer rim

Packing cover central authorities are axial through hole, and the through hole outboard end is formed with inclined-plane in, and inclined-plane is with respect to the tapering that is matched with the axle sleeve front end in this, again, through hole medial extremity wall is horizontal, and is formed with thereon and the screw thread that can be screwed with the screw thread of axle sleeve outer rim

Paraxial rod one end is a flat fixed part, and is formed with fixed orifice on this fixed part, and the other end of paraxial rod forms a jack-post, is formed with oil guide groove simultaneously on this jack-post,

Whereby, the jack-post of this paraxial rod directly wears in the axle sleeve that is assembled in spindle rod, utilizes packing ring to adjust the level of compression of facing paraxial rod in the axle sleeve subsequently, regulates the elasticity when pivoting between major and minor axostylus axostyle.

The utility model can allow whole structure more simplify with appropriate structure collocation, so can simplify assembling flow path, and significantly reduce production costs.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is an element decomposing schematic representation of the present utility model.

Fig. 2, the 3rd, combination cross-section structure configuration schematic diagram of the present utility model wherein demonstrates the situation that packing ring is adjusted.

See also shown in Figure 1ly, it is to be element decomposing schematic representation of the present utility model, wherein can see the utility model and is made of a spindle rod 10, a packing ring 20 and a paraxial rod 30, wherein

Spindle rod 10 1 ends are the fixed part of flat, on this fixed part, be formed with fixed orifice 11, and can be in order to fixing with the computer assembling, the other end of spindle rod 10 then forms the axle sleeve 12 of a hollow, form oblique tapering outside at these axle sleeve 12 front end places, its medial extremity horizontal (seeing also shown in Fig. 2,3) is formed with opening 13 on the axle sleeve 12 again, and is formed with screw thread in axle sleeve 12 outer rims;

Packing cover 20 is in order to screw togather on the axle sleeve 12 that is assembled in

spindle rod

10,20 central authorities are axial through hole at the packing cover, the through hole outboard end is formed with inclined-plane 21 in, should interior inclined-plane 21 be taperings of relative engagement axle sleeve 12 front ends, through hole medial extremity wall is horizontal again, and be formed with screw thread 22 thereon, and can be screwed with the screw thread of axle sleeve 12 outer rims;

Paraxial rod 30 1 ends and spindle rod 10 are a flat fixed part in the same manner, and on this fixed part, be formed with fixed orifice 31, so that fixedly be assembled on the computer, and the other end of paraxial rod 30 forms a jack-post 32, is formed with oil guide groove 33 simultaneously on this jack-post 32;

In assembling the time is to be located in after jack-post 32 with paraxial rod 30 passes packing cover 20 among the axle sleeve 12 of spindle rod 10, and packing cover 20 is screwed on the outside of spindle rod 10 axle sleeves 12, and finishes being assembled of whole pivot device.

After pivot device assembling of the present utility model is finished, only need to adjust the relative position of packing cover 20 on spindle rod 10 axle sleeves 12, can oppress axle sleeve 12 goes packing to be located in wherein paraxial rod 30 jack-posts 32, when 12 pairs of jack-posts 32 of axle sleeve are exerted pressure greatly, friction therebetween will improve, and the stagnation strength when improving computer and launching; Overlapping 20 when packing again loosens, and when allowing 12 pairs of packings of spindle rod 10 axle sleeves overlap pressure that 20 jack-posts 32 are executed to reduce, friction therebetween promptly can reduce, and can increase the smooth degree that opens and closes the computer LCD, pivot device promptly of the present utility model can be adjusted the elasticity of 30 of spindle rod 10 and paraxial rods according to need.

In addition, jack-post 32 outer rims of paraxial rod 30 of the present utility model are provided with oil guide groove 33, jack-post 32 wear be assembled in spindle rod 10 axle sleeves 12 before, ccontaining lubricating oil in this oil guide groove 33 earlier, in the time of so can allowing spindle rod 10 axle sleeves 12 be pivoted relative to each other with 32 intercropping of paraxial rod 30 jack-posts, have appropriate lubricant effect, and unlikely too dry and astringently make a noise even.

Again, overlap in packing of the present utility model and to be provided with rotating hole 23 on 20 outsides, it is to rotate the usefulness of adjusting packing cover 20 with tiny instrument for the user.
