Pivot device

Technical field

The utility model relates to a kind of coupling arrangement, relates in particular to a kind of accurate location, and can the smooth pivot device that pivots.

Background technology

Because the fast development of network video, general computer all can an external camera lens to be used video-signal system, and use for the convenience of the users and carry, at present notebook computer on the market mostly all can built-in camera lens on screen, and can install pivot device between many camera lenses and the computer screen, allow camera lens multi-angle rotate, so this camera lens can be adjusted along with the height of user's head position, even rotatable camera lens is very convenient to shine the object back to computer screen.

See also Fig. 5, shown in Figure 6, existing pivot device includes hollow circular sleeve 70 that is connected in camera lens and the pivot 80 that is connected in computer screen, these sleeve 70 internal sleeve are provided with a C type positioning tube 71, this positioning tube 71 has an opening 711, therefore this positioning tube has elasticity, and be provided with and the fixing stationary installation (not shown) of sleeve 70, and be provided with locating surface 712 in the face of this opening 711 to being less than inside, and these pivot 80 1 ends are provided with the positioning cylinder 81 that inserts this positioning tube 71, and be axially arranged with two plane of orientations 811 in these positioning cylinder 81 surfaces corresponding to this locating surface 712, it is arranged on the position of correspondence and symmetry, after rotating camera lens, it is just rotatable that this positioning cylinder 81 can force positioning tube 71 to utilize its elasticity to enlarge outward, when these plane of orientation 811 complete and these locating surface 712 contrapositions, can reach the effect of location, and because when location, this positioning tube can return to the original form, and allow the user can discover camera lens and locate, and the camera lens that stops operating.

See also Fig. 6, shown in Figure 7, because plane of orientation 811 enters before the locating surface 712, these plane of orientation 811 1 sides can be introduced in the opening 711 of positioning tube 71, this moment, this positioning tube 71 will be replied its shape a little, therefore can allow the people feel has vibrations slightly, camera lens is gone to the location and allow the user take for, and the camera lens that stops operating, but this plane of orientation 811 does not reach locating surface 712 in fact, promptly do not reach the accurate in locating position, thereby can obscure the user and the puzzlement of the location that makes the mistake.

The utility model content

Technical problem underlying to be solved in the utility model is, overcomes the problem that existing pivot device can make a mistake and locate when the camera lens of location, and a kind of accurate locating effect that has is provided, and can the smooth pivot device that pivots.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of pivot device is characterized in that, comprising: in conjunction with bolster, it has a circular sleeve and a joint portion, and this sleeve is provided with an opening and a perforation, and is provided with a slot in an inner side, and this joint portion one is connected in the pertusate end of sleeve; At least one circular positioning tube, it is arranged on sleeve inner, and is provided with and can snaps in slot fixing the clamping block of this positioning tube, and this positioning tube one side shaft is to being provided with a location division, it is formed on the flat surfaces of positioning tube inside at least, and is provided with stepped locating slot in this location division subtend; Pivot, it is that opening from sleeve wears to sleeve, and the end in being located in positioning tube is provided with the positioning cylinder that is inserted in the positioning tube, this positioning cylinder outside is axially arranged with two plane of orientations corresponding to this location division, two plane of orientations are arranged on the position of subtend, and this positioning cylinder one end is provided with the fixedly projection of the perforation that passes sleeve; Fixed block, it is arranged on the pertusate end of the sleeve outside, and combines with the fixedly projection of pivot.

Aforesaid pivot device, wherein locating slot is that the opposite end of self-align tube extends in the middle of the positioning tube, and extends to interconnect in intermediate radial.

Aforesaid pivot device, wherein the positioning cylinder adapter ring is provided with a recess.

Aforesaid pivot device, wherein fixed block has one and inserts with the fixed orifice of fixed pivot axi in sleeve for fixing projection, and this fixed block is blocked in the stop part outside the perforation of sleeve.

Aforesaid pivot device, wherein the outside of stop part is provided with the portion that is convexly equipped with that can touch circuit in the pivot device rotary course.

This is installed in respectively on camera lens and the computer screen in conjunction with bolster and pivot, because the locating slot of this positioning tube is stepped, therefore can allow positioning tube expand and to dwindle, and when a plane of orientation of positioning cylinder will enter the location division, can allow another plane of orientation can not fall in the locating slot, so the situation of wrong location in the time of can not allowing the user use is so reach the purpose of this utility model.

The beneficial effects of the utility model are that it has accurate locating effect, and can the smooth advantage that pivots.
