Abstract
The utility model provides a damping shaft for multi-angle positioning on a rotary angle, relates to the field of damping shafts, and solves the problem of very high manufacturing cost caused by a reason that a traditional damping shaft is used for fixing a television position by a damping force. The damping shaft comprises a concentric shaft, a shaft sleeve, a spring and a roll ball, wherein the shaft sleeve is sleeved on the concentric shaft; a roll ball groove is formed in the concentric shaft; the spring and the roll ball are arranged in the roll bal groove; a positioning hole opposite to the roll ball groove is formed in the shaft sleeve; and one end of the spring is used for supporting the roll ball in the positioning hole. The damping shaft has the advantages that the multi-angle limitation on the rotary angle of the damping shaft can be achieved, so that the manufacturing cost of the damping shaft can be reduced.
Description
Technical field
The utility model relates to a kind of damping shaft, especially relates to a kind of damping shaft that angle of swing is carried out to the multi-angle location.。
Background technique
Flat panel TV generally all is fixed on television support, in order to realize flat panel TV, can rotate adjusting, can between flat panel TV and television support, damping shaft be set.Traditional damping shaft mainly contains concentric shafts and axle sleeve forms, the TV backboard is fixed on axle sleeve, concentric shafts is fixed on television support, axle sleeve can rotate along concentric shafts, have damping force between concentric shafts and axle sleeve, when TV forwards several angle to, can rely on damping force to fix the TV position, such damping shaft is selected all very strict to the material of the design of its processing request, torque magnitude and damping shaft part, thereby its manufacture cost is also corresponding very high.
Summary of the invention
The purpose of this utility model is: the problem existed for prior art, provide a kind of the realization to carry out the multi-angle restriction to the angle of swing of damping shaft, thus can reduce the damping shaft manufacture cost angle of swing is carried out to the damping shaft of multi-angle location.
The purpose of this utility model is achieved through the following technical solutions:
A kind of damping shaft that angle of swing is carried out to the multi-angle location, it is characterized in that, this damping shaft comprises concentric shafts, axle sleeve, spring and ball, described axle sleeve is enclosed within on concentric shafts, this concentric shafts is provided with ball grooves, spring and ball are arranged in ball grooves, and axle sleeve is provided with the positioning hole relative with ball grooves, and an end of spring withstands on ball in positioning hole.
Preferably, described concentric shafts is divided into two sections, and an end of one section concentric shafts is provided with block tongue, and an end of another section concentric shafts is provided with draw-in groove, two sections mutual clampings of concentric shafts.
Preferably, described ball grooves is arranged on the concentric shafts with block tongue.
Preferably, the one-week interval along axle sleeve is provided with a plurality of positioning holes.
Compared with prior art, the utility model can be realized the angle of swing of damping shaft is carried out to the multi-angle restriction, play certain angle of rotation positioning action, so just can bring larger convenience for the electric equipments such as flat panel TV, flat panel display, desk lamp, lighting set use, and can reduce the processing request of damping shaft, can suitably reduce in the design of torque magnitude, select also can suitably lower the requirement at the material of damping shaft part, this can bring larger advantage on cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The decomposition texture schematic diagram that Fig. 2 is Fig. 1;
The cross section structure schematic diagram that Fig. 3 is Fig. 1;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of damping shaft that angle of swing is carried out to the multi-angle location, this damping shaft comprises concentric shafts, axle sleeve 1, spring 5 and ball 6.Axle sleeve 1 is enclosed within on concentric shafts 2, and this concentric shafts 2 is provided with ball grooves 8, and spring 5 and ball 6 are arranged in ball grooves 8, and axle sleeve 1 is provided with the positioning hole 9 relative with ball grooves 8, and an end of spring 5 withstands on ball 6 in positioning hole 9.The end that concentric shafts is divided into two sections 2,7, one sections concentric shafts 7 is provided with block tongue 10, and an end of another section concentric shafts 2 is provided with 11, two sections mutual clampings of concentric shafts of draw-in groove.Ball grooves 8 is arranged on the concentric shafts 7 with block tongue.One-week interval along axle sleeve 1 is provided with a plurality of positioning holes 9, positioning hole 9 number can be set according to actual needs, the present embodiment arranges three positioning holes.
Clamping in the middle of two sections concentric shafts 2,7, two ends respectively are fixed on support 4 by screw 3, under the effect of torsion, axle sleeve 1 starts to rotate around the concentric shafts 2,7 that is fixed on the mutual clamping on support 4 with screw 3, when turning to several angle a1, be arranged on the elastic force effect that the ball 6 of concentric shafts 7 ball grooves 8 on interior is subject to spring 5, head in the positioning hole 9 on axle sleeve 1, realize the location to angle of rotation a1.Now, the card power of 6 pairs of axle sleeves 1 of ball is F2, the nominal torsion of damping shaft is F1, and when axle sleeve 1 is greater than the torsion of " F1+F2 ", ball 6 is squeezed in ball grooves 8, lose the screens effect, axle sleeve 1 now only need be subject to being greater than the torsion of F1, just rotatable, until arrive next orientation angle, by that analogy, realize a1, a2, a3 .... the location at angle.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all any modifications of doing within spirit of the present utility model and principle, be equal to replacement and improvement etc., within all should being included in protection domain of the present utility model.
