Description

The lifting pivot of notebook computer, liquid crystal screen and LCD TV

Technical field:

The utility model relates to the pivot technical field, refers in particular to a kind of lifting pivot of notebook computer, liquid crystal screen and LCD TV of damping size of scalable pivot.

Background technology:

Along with popularizing of notebook computer, liquid crystal screen and LCD TV, people also improve constantly the requirement of its quality, this series products makes the problem no more than its screen pivotal axis that the people perplexs most in early days, because the screen pivotal axis must can have suitable damping action, be beneficial to the user and when raising screen, can be stuck in any suitable angle position according to need.As shown in Figure 1, existing a kind of screen pivot just by the axle sleeve 03 of the stator 01 that is connected be connected 04 simple nested composition of pin-jointing piece 02 rotating shaft, this pivot is because structural restriction, so that lack the function of regulating the damping size, its damping size is a fixed value comparatively speaking, the excessive or too small normal use that all can influence screen.As shown in Figure 2, the screen pivot structure that occurs a kind of damping size of scalable pivot subsequently, its rotating shaft 05 is formed in one, the one end stator 06 that is connected, and other end socket pivot sheet 07 is back by a nut 08 interlocking roof pressure pivot sheet 07, and its damping size of regulating pivot is to realize by paying for some pads 09 first.This pivot structure is in actual use, and along with the continuous open and close of screen, interlocking nut 08 rotation relatively will inevitably take place and gets loose situation, and decline damping size finally can't support screen, causes unpredictalbe situation to take place.Pay for the method that some pads 09 reach the damping size of regulating pivot first for employing simultaneously, its also suitable time-consuming taking a lot of trouble that operate is brought inconvenience to the user.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, and a kind of function that had both had the damping size of regulating pivot is provided, and the damping size adjustment is more convenient, the lifting pivot of notebook computer, liquid crystal screen and LCD TV efficiently.

The utility model is achieved by the following technical solution: sleeve joint hole socket one pivot of location axle sleeve, the socket end of this pivot is provided with cuts the formula gap slot open, pivot also is provided with the axially extending bore that runs through its two ends simultaneously, wherein in the outer end of pivot, offer the internal thread of being convenient to the bolt screw-in, and the outer peripheral edges of outer end are provided with the external thread of attaching nut interlocking along through hole; Described pin-jointing piece is set in outside the pivot on the end, and by the lug boss cramping of nut and pivot.

The footpath is slightly larger than the aperture of the sleeve joint hole of location axle sleeve outside the socket end of described pivot, and the tapered shape of partial through holes of socket end inside.

Have one on the outer end of described pivot at least and scabble face, and the shape of holding outside sleeve joint hole on the pin-jointing piece and the pivot is complementary; The tapered shape of front end that described bolt screws in.

The socket end of pivot of the present utility model is provided with gap slot, when pivot is plugged in the sleeve joint hole of location axle sleeve, owing to the gap of gap slot slightly folds the socket end of pivot.When needing to regulate pivot damping size, can realize that by swivel bolt the bolt precession then can support the socket end of pivot, thereby increase the damping due to rotation of pivot; Otherwise bolt revolves and moves back the damping due to rotation that then can suitably reduce pivot, and its adjusting is very convenient, quick, guarantees the normal upset of screen, has improved the quality of product.

Accompanying drawing 2 is the structural representation of existing another kind of screen pivot;

Accompanying drawing 3 is a schematic perspective view of the present utility model;

Accompanying drawing 4 is a perspective exploded view of the present utility model;

Accompanying drawing 5 is a combination cross-sectional schematic of the present utility model.

Embodiment:

See accompanying drawing 3～5, the utility model includes location axle sleeve 1, stator 2 and pin-jointing piece 3, and an end of location axle sleeve 1 is fixedlyed connected with stator 2, and the other end is provided with axial sleeve joint hole 11.Sleeve joint hole 11 sockets one pivot 4 of location axle sleeve 1, the footpath is slightly larger than the aperture of sleeve joint hole 11 of location axle sleeve 1 outside the socket end 41 of pivot 4, and promptly the two is an interference fit, and socket end 41 is provided with and cuts formula gap slot 411 open; Pivot 4 also is provided with the axially extending bore 42 that runs through its two ends simultaneously, partial through holes 42 tapered shapes in socket end 41 inside, and offer the internal thread 431 that the bolt 5 of being convenient to the tapered shape of front end screws in along through hole 42 in the outer end 43 of pivot 4, and the outer peripheral edges of outer end 43 are provided with the external thread 432 of attaching nut 6 interlockings.Pin-jointing piece 3 is set in outside the pivot 4 on the end 43, and by lug boss 44 crampings of nut 6 and pivot 4.Have at least one to scabble face 433 on the outer end 43 of pivot 4, and the shape of end 43 is complementary outside sleeve joint hole 31 on the pin-jointing piece 3 and the pivot 4.

During assembling, the socket end 41 of pivot 4 is pegged graft to go into to locate in the sleeve joint hole 11 of axle sleeve 1, also between pivot 4 and location axle sleeve 1, one or more oil sealing rubber sheet gaskets 7 are set simultaneously, in case leak-stopping is oily and bleed back; Again pin-jointing piece 3 is socketed on the outer end 43 of pivot 4 subsequently, and cooperates external thread 432 interlocking roof pressure pin-jointing pieces 3 by nut 6.Because the outer end 43 of pivot 4 is provided with the face of scabbling 433, and the shape of end 43 is complementary outside sleeve joint hole on the pin-jointing piece 3 31 and the pivot 4, thereby the location is convenient, is assembled more firm.The footpath is slightly larger than the aperture of the sleeve joint hole 11 of location axle sleeve 1 outside the socket end 41 of pivot 4, and which is provided with gap slot 411, thereby the socket end 41 of pivot 4 is when inserting the sleeve joint hole 11 of location axle sleeves 1, owing to the gap of gap slot 411 slightly folds the socket end 41 of pivot 4, the through holes 42 in the socket end 41 dwindle.When damping is big or small between needs adjusting pivot 4 and the location axle sleeve 1, can realize regulating purpose by swivel bolt 5, slightly fold when wherein utilizing the tapered and socket end 41 of the through hole 42 of socket end 41 inside to peg graft, when bolt 5 precessions, then can support the socket end 41 of pivot 4, thereby increase the damping due to rotation between pivot 4 and the location axle sleeve 1; Otherwise bolt 5 revolves and moves back the damping due to rotation that then can suitably reduce pivot 1.The utility model is assembled more firm, and the fault that gets loose such as nut can in use not take place, and it is very convenient, quick to regulate pivot 1 damping size, guarantees the normal upset of screen, has improved the quality of product.

Stator 2 of the present utility model can not need be designed to the shape of bending process as required, and is directly one-body molded with location axle sleeve 1; Certainly, multiple shape can also be arranged, all fall within the protection domain of the present utility model for location axle sleeve 1 and stator 2.
