Abstract
The utility model relates to a self-locking type limit turning device, comprising a support, a spindle and a turning part, wherein the turning part is fixed on the spindle, a rotatable part is arranged on the turning part, a fixed part is arranged on the spindle, a locking groove and an arc limit groove are arranged on the rotatable part, dead holes and a locating part are arranged on the fixed part, springs and needle rollers are arranged inside the dead holes, and the locating part extends into the arc limit groove. The utility model achieves the aims of limit and self locking as the self locking type limit turning device does not swing randomly due to external forces, the limit effect and the self locking performance are good, the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to a kind of turning device, the spacing turning device of especially a kind of self-locking.
Background technology
Existing turning device, it is strength upset by himself, to reach double-faced effect, and owing to the deadweight of lamp box immobilizes, its turning device angle can only be fixed on the angle, but rock in case there is outside power to produce, for the angle difference of different occasions uses, the angle of its adjusting is also different like this.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of spacing self-locking good, that can not rock spacing turning device.
The technical scheme that its technical problem that solves the utility model adopts is: the spacing turning device of a kind of self-locking, comprise support, main shaft and flip piece, flip piece is fixed on the main shaft flip piece and is provided with rotatable parts, main shaft is provided with fixed part, on rotatable parts, be provided with draw-in groove and arc stopper slot, fixed part is provided with blind hole and locating part, is provided with spring and needle roller in the blind hole, and locating part extend in the arc stopper slot.
The rotation limit of described arc stopper slot is 180 degree.
The draw-in groove that described rotatable parts are provided with is two.
The beneficial effects of the utility model are: the utility model is easy to use, and is simple in structure, can arbitrarily not swing because of the strength of outside, reached spacing and purpose self-locking, and spacing good, and self-locking property is strong, and the scope of application is extensive.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model rotatable parts and structural representation after fixed part cooperates.
Fig. 3 is the cutaway view of Fig. 2.
Fig. 4 is the structural representation of the utility model rotatable parts.
Fig. 5 is the structural representation of the utility model fixed part.
Among the figure: 1. support 2. main shafts 3. flip pieces 4. rotatable parts 4-1. draw-in groove 4-2. arc stopper slots 5. fixed part 5-1. blind hole 5-2. locating parts 6. springs 7. needle rollers.
The specific embodiment
The spacing turning device of self-locking as shown in Figure 1, comprise support 1, main shaft 2 and flip piece 3, flip piece 3 is fixed on main shaft 2, flip piece 3 is provided with rotatable parts 4, main shaft 2 is provided with fixed part 5, on rotatable parts 4, be provided with draw-in groove 4-1 and arc stopper slot 4-2, fixed part 5 is provided with blind hole 5-1 and locating part 5-2, be provided with spring 6 and needle roller 7 in the blind hole 5-1, locating part 5-2 extend in the arc stopper slot 4-2, so just guaranteed just can not rotate again after turning device forwards certain position to, just can only rotate to a direction.
When turning device overturns, rotatable parts 4 rotate around main shaft 2, locating part 5-2 spacing be 180 the degree arc stopper slot 4-2 in rotate, needle roller among the draw-in groove 4-1 at one end produces draw-in groove 4-1, along with locating part 5-2 motion, when turning to 180 when spending, needle roller 7 is compressed into the draw-in groove 4-1 of the other end under the conflict effect of spring 6, tightened rotatable parts 4 and fixed part 5, turning device rotates with orientation only, the phenomenon of avoiding turning device arbitrarily to rock owing to outside strength.
