Description

Tripod The Cloud Terrace seat

[technical field]

The utility model relates to a kind of tripod, especially relates to a kind of tripod The Cloud Terrace seat.

[background technology]

General video camera to be contained on the The Cloud Terrace seat and to make camera base in conjunction with not rotating really in order locking, tend under the The Cloud Terrace seat, up lock fixedly screw, hold out against camera base, and to have middle pipe can draw high in the pipe just have living space by under the The Cloud Terrace up locking screw hold out against camera base.And the middle pipe of this hemispheric cloud platform, so can not be by locking screw space up under the The Cloud Terrace because of not drawing high.

[utility model content]

Provide a kind of and can adjust the tripod The Cloud Terrace seat of realizing holding out against camera base from the side, concrete scheme is:

A kind of tripod The Cloud Terrace seat comprises axial hole, is arranged on the part that axially fastens in this axial hole, wherein, also comprises radial screw bore and is arranged on the interior radially securing member of this radial screw bore; Described radial screw bore and described axial hole quadrature; Described first section of part of axially fastening is away from described radial screw bore and have first inclined-plane; First section close described axial hole, latter end of described radially securing member are threaded with described radial screw bore.

Preferably, the described part that axially fastens is the multidiameter of first section external diameter greater than the latter end external diameter, and described axial hole is a shoulder hole; The described sheathed spring of latter end that axially fastens part.

Preferably, described radially securing member comprises radially a multidiameter and the double-screw bolt that cooperates with described radial screw bore; The circular hole of the thin segment of described radially multidiameter is held in one end setting of this double-screw bolt.

Preferably, thick section of described radially multidiameter has and the second suitable inclined-plane of described first inclined-plane.

Preferably, described double-screw bolt is the countersunk head double-screw bolt.

Preferably, described double-screw bolt stretches out described threaded hole.

This tripod The Cloud Terrace seat utilizes the radial screw bore and the described axial hole of one group of quadrature, rotating its first section of securing member radially offsets to first inclined-plane that axial hole moved and axially fastened part, along with the radially continuation precession of securing member, its first section props up first inclined-plane and realizes axially fastening the lifting of part, and then has reached the purpose that holds out against camera base from the side adjustment of The Cloud Terrace seat.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model is described in detail.

The tripod The Cloud Terrace seat 200 of present embodiment, as Fig. 1, Fig. 2 and shown in Figure 3, comprise axial hole 250, radial screw bore 280, be arranged on and axially fasten part 260 in this axial hole 250, be arranged on the radially securing member 290 in this radial screw bore 280, described radial screw bore 280 and described axial hole 250 quadratures; Described first section of part 260 of axially fastening is away from described radial screw bore 280 and have first inclined-plane 261; First section close described axial hole 250, latter end of described radially securing member 290 are threaded with described radial screw bore 280.

Rotate radially securing member 290, its first section first inclined-plane 261 that moves and axially fasten part 260 to axial hole 250 offsets, along with the radially continuation precession of securing member 290, its first section props up first inclined-plane 261 and will axially fasten part 260 and eject in The Cloud Terrace seat 200 surfaces, plays the purpose that holds out against bulb base anti-rotation.

For after radially securing member 290 is back-outed radial screw bore 280, axially fastening part 260 can in time reset, at the described sheathed spring 220 of latter end that axially fastens part 260, the described part 260 that axially fastens is first section external diameter multidiameters greater than the latter end external diameter, and described axial hole 250 is shoulder holes; When axially fastening part 260 when being lifted to the extreme higher position, the two ends of this spring 220 are against respectively on the step surface of multidiameter and shoulder hole.

In order to ensure ramp effect and reduce wearing and tearing to first inclined-plane 261, described radially securing member 290 produced be divided into radially a multidiameter 291 and a double-screw bolt 293, double-screw bolt 293 cooperates with described radial screw bore 280, the circular hole 294 of the thin segment of described radially multidiameter 291 is held in an end setting of this double-screw bolt 293.Adopt this structure, when double-screw bolt 293 rotations were screwed into radial screw bore 280, radially 291 meetings of multidiameter can not follow double-screw bolt 293 to rotate together with the straight-line displacement that double-screw bolt 293 moves, thereby have reduced the radially wearing and tearing on securing member 290 diameters first inclined-plane 261.

For further reducing wearing and tearing to first inclined-plane 261, improve degree of regulation simultaneously, thick section of described radially multidiameter 291 has and the second suitable inclined-plane 292 of described first inclined-plane 261.Axially fasten part 260 liftings radially during securing member 290, the second suitable inclined-plane 292 is that face contacts with first inclined-plane 261, than such scheme, has increased the contact area with first inclined-plane 261, has further reduced the wearing and tearing to first inclined-plane 261; Elongated the adjustable range of double-screw bolt 293 simultaneously, the height that the double-screw bolt 293 same radially securing members 290 of adjustable range in this programme are lifted has reduced, so improved degree of regulation.

Stretch out radial screw bore 280 for fear of described double-screw bolt 293, collided impaired situation and convenient tight with the wrench commentaries on classics, described double-screw bolt 293 is countersunk head double-screw bolts 293, and countersunk head can adopt forms such as interior hexagonal, flat recess, cross recess, rice pilot trench.Certainly, the also extended radial screw bore 280 of described double-screw bolt 293 exposes outside the The Cloud Terrace seat 200, mat turn-knob or pull the turn of buckleing handled easily double-screw bolt 293.

Below only expressed several embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
