Description

The tripod supporting foot

[technical field]

The utility model relates to the photographic goods field, especially relates to a kind of tripod supporting foot that is used for photographic tripod.

[background technique]

In traditional tripod supporting foot, use is gone up on the soft ground (as dirt floor) that is adapted at that has, and use is gone up on the firm ground (as the cement flooring) that is adapted at that has.So just cause and need change corresponding tripod supporting foot at different surface states, thus very inconvenient use.

[model utility content]

In view of this, be necessary to provide a kind of and can adapt to various surface states and the convenient tripod supporting foot that uses.

A kind of tripod supporting foot, comprise outer tube, the pin nail, foot pad, nut, connector portions, the pin pipe joint, facing, one end of described connector portions embeds an end of pin pipe joint, one end of described facing embeds the other end of pin pipe joint, the inwall of described facing is provided with the screw thread track, described pin nails on and is provided with the slip screw thread that cooperates socket with facing, described pin nail comprises nail head and afterbody, the afterbody of described nut and pin nail is spirally connected and places the endoporus of connector portions, described foot pad is fixedlyed connected with facing and is socketed on pin nail outside, and described outer tube sleeve is connected on the pin pipe joint and fixedlys connected with connector portions with the connector portions outside and with the pin pipe joint.

When above-mentioned tripod supporting foot uses on soft ground, make the pin nail expose foot pad, make the pin nail contact support with ground by the rotation foot pad; When on firm ground, using, make pin nail withdrawal foot pad, make foot pad contact support with ground by the rotation foot pad.Therefore above-mentioned tripod supporting foot can be applicable to various ground, and only needs the rotation foot pad to get final product in use, uses easily.

In preferred embodiment, described facing outer wall is provided with recessed circular groove, and described pin pipe joint inwall is provided with the protruding barb of wedge shape, and described facing interference embeds the pin pipe joint makes circular groove cooperate with described protruding barb.

Facing is the flexible critical component of control pin nail, and the fit system of facing and pin pipe joint can make facing only can rotate and can not move along its axis.

In preferred embodiment, described facing head is that rectangular, ellipse, triangle, square, pentagon or Hexagon block member cooperate with foot pad.

In preferred embodiment, described nut is a rectangular, ellipse, and triangle, square, pentagon or hexagon nut, the inner hole section of described connector portions are and the corresponding shape of nut.

[embodiment]

As shown in Figure 1, be tripod supporting foot decomposition texture schematic representation.This tripod supporting foot comprises outer tube 10, nut 20, connector portions 30, pin pipe joint 40, facing 50, pin nail 60 and foot pad 70.

Outer tube 10 is the columnar member of inner hollow, and the inwall of hollow is provided with bar shaped fin 11 longitudinally.

Connector portions 30 comprises Embedded Division 31 and main body 32, and main body 32 is an outer circular and the columnar member that is provided with endoporus 33, is provided with first bar-shaped trough 34 longitudinally in the circular outer wall of main body 32.The shape of this endoporus 33 is identical with the shape of nut 20, can be rectangular, ellipse, triangle, square, pentagon or Hexagon, is preferably hexagon nut, and the shape of endoporus 33 also is a Hexagon.

Pin pipe joint 40 is the columnar member of inner hollow, and the suitable connector portions 30 that makes of Embedded Division 31 shapes of its inner wall shape and connector portions 30 can be joined with 40 embeddings of pin pipe joint.The outer wall of pin pipe joint 40 is provided with second bar-shaped trough 41 longitudinally, and inwall is provided with the protruding barb 42 of wedge shape (referring to Fig. 2).Based on consideration attractive in appearance, also can on rubber hose coupling 40, establish annular ring lid 43.

Facing 50 heads 51 are rectangular, ellipse, triangle, square, pentagon or Hexagon block member, are preferably the Hexagon outer wall and are provided with recessed circular groove 52, and inwall is provided with screw thread track 53.

The two ends of pin nail 60 are respectively nail head 61 and afterbody 63, and outer wall is provided with slip screw thread 62.

Foot pad 70 is the annular cylindrical part.Assembling mode is as follows:

Connector portions 30 is joined by Embedded Division 31 and pin pipe joint 40 1 ends, and first bar-shaped trough 34 is docked with second bar-shaped trough 41.The mode brute force that facing 50 embeds with interference penetrates pin pipe joint 40 makes protruding barb 42 embed circular groove 52, and facing 50 can only rotate in pin pipe joint 40 and can't move vertically.The slip screw thread 62 of pin nail 60 by its outer wall and screw thread track 53 fit into facing 50 inwalls, and make its afterbody 63 extend to the endoporus 33 of connector portions 30, nut 20 and pin nail 60 are spirally connected at afterbody 63, and place the endoporus 33 suitable with its shape.The head of facing 50 is by foot pad 70 overcoats and fixedly connected.Outer tube 10 is enclosed within the connector portions 30 that connects and the outside of pin pipe joint 40, and fin 11 is engaged with first bar-shaped trough 34 and second bar-shaped trough 41.

Working method is as follows:

Nut 20 can move up and down in the endoporus 33 of connector portions 30, connector portions 30 and pin pipe joint 40 relative fixed, and facing 50 can rotate with respect to pin pipe joint 40.Foot pad 70 is fixedlyed connected with facing 50, and foot pad 70 rotates and can drive facing 50 rotations, cooperates slip screw threads 62 that pin nail 60 is moved vertically by screw thread track 53.

As shown in Figure 2, stretch out the schematic representation of foot pad 70 for this tripod supporting foot.Keep outer tube 10, connector portions 30 and pin pipe joint 40 motionless, the foot pad 70 that turns clockwise drives facing 50 and rotates, and pin nail 60 is moved down can make the nail head 61 of pin nail 60 stretch out foot pad 70.

As shown in Figure 3, be the schematic representation of this tripod supporting foot withdrawal foot pad 70.Being rotated counterclockwise foot pad 70 just can make the nail head 61 of pin nail 60 return foot pad 70.

This tripod supporting foot can be applicable to various ground, and only needs the rotation foot pad to get final product in use, uses easily.And the part that adopts is few, and design of part is simpler, is easy to processing, and assembling is simple.Batch process can greatly be enhanced productivity and be saved cost.

The above embodiment has only expressed several mode of execution of the present utility model, and 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.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
