Abstract
The utility model discloses a tripod supporting structure which comprises a middle shaft tube, a connecting seat and three support leg tubes. The middle shaft tube is fixedly arranged at the upper end of the connecting seat, the three supporting leg tubes are hinged to the lower end of the connecting seat, a rotating sleeve and a supporting pad capable of rotating around the central axis of the rotating sleeve are arranged at the lower end of the connecting seat, and three protruded blocks which respectively abut against the three supporting leg tubes to be located are arranged in the peripheral direction of the supporting pad. The tripod supporting structure is simple in structure, stable in supporting and convenient to operate.
Description
Technical field
The utility model relates to tripod technical field, especially relates to a kind of tripod supporting structure.
Background technique
Tripod is a kind ofly can to devices such as spraying devices, play the supporting frame of steady supporting effect, comprises middle stern tube, connecting base and three support leg pipes, and middle stern tube is fixedly installed on the upper end of connecting base, and three support leg pipes are articulated with the lower end of connecting base.Because support leg pipe is flexibly connected with connecting base, therefore, when tripod struts, three support leg pipes do not have the device of supporting and location, can exist and close up trend, cause tripod to support built on the sand.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model will provide a kind of tripod supporting structure that has, and it is simple in structure, supports firm, easy to operate.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of tripod supporting structure, comprise middle stern tube, connecting base and three support leg pipes, middle stern tube is fixedly installed on the upper end of connecting base, article three, support leg pipe is articulated with the lower end of connecting base, the lower end of described connecting base is provided with rotary sleeve and can, around the Support cushion of described rotary sleeve central shaft rotation, be upwards provided with three corresponding with described three support leg pipes respectively projections the week of described Support cushion.
Wherein, it is inner that described rotary sleeve is sheathed on described Support cushion, offers the guiding groove of arc on the sidewall of described rotary sleeve, and the madial wall of described Support cushion is provided with the projection matching with described guiding groove, and described guiding groove is provided with the breach snapping in for described projection.Described three support leg pipes be take described middle stern tube and are distributed as axle becomes even circumferential, and the radian of described guiding groove is π/3.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
Tripod supporting structure described in the utility model, because the lower end at connecting base is provided with rotary sleeve Support cushion, rotary sleeve is fixedly connected with connecting base, and Support cushion can rotate on rotary sleeve, is upwards provided with in the week of Support cushion respectively and offset three projections of location of described three support leg pipes.When tripod is opened, rotational support pad make three projections respectively with three support leg pipes location that offsets, can prevent that three support leg pipes from drawing in, now tripod is in the stable holding state of opening.But in the time of need to drawing tripod in, rotational support pad makes three projections lay respectively at three positions, space between support leg pipe, and three support leg pipes can draw in.It is simple in structure, supports firm, easy to operate.

Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see shown in Fig. 1 to Fig. 7: a kind of tripod supporting structure, comprise middle stern tube 1, connecting base 2 and three support leg pipes 5, article three, support leg pipe 5 be take middle stern tube 1 and is distributed as axle becomes even circumferential, middle stern tube 1 is fixedly installed on the upper end of connecting base 2, article three, support leg pipe 5 is articulated with the lower end of connecting base 2, the Support cushion 3 that the lower end of connecting base 2 is provided with rotary sleeve 4 and can rotates around rotary sleeve 4 central shafts, rotary sleeve 4 is sheathed on Support cushion 3 inside, on the sidewall of rotary sleeve 4, offer the guiding groove 41 of arc, the radian of guiding groove 41 is π/3, on the madial wall of Support cushion 3, convex with the projection 32 matching with guiding groove 41, guiding groove 41 is provided with the breach 42 snapping in for projection 32, projection 32 snaps in guiding groove 41 by breach 42, the rotation angle of Support cushion 3 under the position-limiting action of guiding groove 41 is 60 °, upwards be provided with in the week of Support cushion 3 respectively and offset three projections 31 of location of three support leg pipes 5.When tripod is opened, rotational support pad 3 make three projections 31 respectively with three support leg pipes 5 location that offsets, can prevent that three support leg pipes 5 from drawing in, now tripod is in the stable holding state of opening.But in the time of need to drawing tripod in, rotational support pad 3 makes three projections 31 lay respectively at three positions, space between support leg pipe 5, and three support leg pipes 5 can draw in, be convenient to packing.It is simple in structure, supports firm, easy to operate.
