Abstract

The utility model relates to a rotary control mechanism on a camera tripod, which comprises an inner alligatoring ring (1), an outer alligatoring ring (2), an axle sleeve (4) and a pin shaft (6). The surface of the inner alligatoring ring (1) is provided with a dummy club (7). The inner alligatoring ring (1) is nested on the front part of the pin shaft (6). The surface of an inner chamber (13) of the outer alligatoring ring (2) is provided with a plurality of concave grooves (8). The shape of the dummy club (7) is corresponding with the shapes of the concave grooves (8). The outer alligatoring ring (2) is sheathed in the top part of the axle sleeve (4), and the outer alligatoring ring (2) is fixed with axle sleeve (3). The dummy club (7) on the inner alligatoring ring (1) is embedded in the concave grooves (8) of the outer alligatoring ring (2). A camera A component (5) is fixed with the tail section of the pin shaft (6) together. A camera B component (3) is fixed with the axle sleeve (4) together. The rotary control mechanism on camera tripod can make the camera A component and the camera D component (3) positioning exactly during the rotation. The connection is firm, and can not rotate at will. The structure is simpler, and the obvious section sense can be produced. The operation is simple, convenient and intuitionistic.

Description

Rotation controling mechanism on the camera trivets

1, technical field:

The utility model relates to the rotation controling mechanism on the camera trivets.

2, background technique:

At present, the present camera platform of using on tripod three-dimensional The Cloud Terrace in various photographies, the rotary camera platform can only be made simple horizontal vertical and take, and can't accurately locate, and fixedly dynamics deficiency, instability have so influenced the effect of photographing greatly.

3, summary of the invention:

The purpose of this utility model provides the rotation controling mechanism rotation controling mechanism on the camera trivets, it utilizes closely cooperating of internal gear and outer tooth ring, can accurately locate when making the rotary camera platform, and cut behind the location more firm, more stable, favourable and photographer improves the quality of photography.

The utility model is achieved by the following technical solution: it is made up of internal gear, outer tooth ring, axle sleeve and bearing pin, the internal gear surface is provided with boss, the bearing pin front that internal gear is nested in, the surface of the inner chamber of outer tooth ring is provided with several grooves, the shape of boss is corresponding with the shape of groove, outer tooth ring is enclosed within the inside, axle sleeve top and is fixed together with axle sleeve, boss on the internal gear is embedded into the groove the inside of outer tooth ring, the afterbody of camera A member and bearing pin installs and fixes together, and camera B member and axle sleeve install and fix together.

The sectional shape of above-mentioned described hollow groove, solid edge sealing can be circular.

The sectional shape of above-mentioned described hollow groove, solid edge sealing can be a rectangular.

Above-mentioned described camera B member is the camera support seat, and camera A member is a camera platform.

The utility model compared with prior art has following advantage: it utilizes closely cooperating of internal gear and outer tooth ring, can accurately locate when being the rotation of camera A member and camera B member, and back, location camera A member is connected more firm with camera B, can at will not rotate, structure is comparatively simple, and is clear and melodious at camera A member and camera B sound when rotating, firmly ascending, produce tangible section sense, simple to operation directly perceived.

4, description of drawings:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is an internal gear structure sectional view of the present utility model;

Fig. 2 is the structure sectional view of outer tooth ring of the present utility model;

Fig. 3 is the structural drawing after internal gear of the present utility model, outer tooth ring, the bearing pin assembling;

Fig. 4 is the structural drawing after the utility model is applied in camera support seat and camera platform;

Fig. 5 is the user mode figure after camera support seat and the camera platform that is applied in of the present utility model.

5, embodiment:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model is by internal gear (1), outer tooth ring (2), axle sleeve (4) and bearing pin (6) are formed, internal gear (1) surface is provided with boss (7), bearing pin (6) front that internal gear (1) is nested in, the surface of the inner chamber (13) of outer tooth ring (2) is provided with several grooves (8), the shape of boss (7) is corresponding with the shape of groove (8), outer tooth ring (2) is enclosed within the inside, axle sleeve (4) top and is fixed together with axle sleeve (3), boss (7) on the internal gear (1) is embedded into groove (8) the inside of outer tooth ring (2), camera A member (5) installs and fixes together with the afterbody of bearing pin (6), and camera B member (3) installs and fixes together with axle sleeve (4).The shape that is boss (7) and groove (8) can arch.The groove (8) that the internal surface of outer tooth ring (2) is provided with is evenly arranged by circumference.

As shown in Figure 4, the utility model also comprises a locking framework, this locking framework comprises nut (9) and spring (10), spring (10) is enclosed within on the bearing pin (6) and is positioned between the internal gear (1) and the shaft shoulder (14), the end face of the shaft shoulder (14) is provided with tooth (11), the end face of outer tooth ring (2) is provided with lower tooth (12), last tooth (11) and lower tooth (12) engagement, and nut (9) is connected the front end of the bearing pin (6) on the camera platform (5).Camera B member (3) is the camera support seat, and camera A member (5) is a camera platform.

As shown in Figure 3, principle of the present utility model is: swivel nut (9) unclamps locking framework, lower tooth (12) on the end face that makes outer tooth ring (2) under the effect of spring (10) separates with the last tooth (11) of the end face of the shaft shoulder (14), rotary camera A member (5) also drives bearing pin (6) rotation, bearing pin (6) drives internal gear (1) and rotates, resiliently deformable takes place and leaves the lip-deep groove of outer tooth ring (2) inner chamber (13) (8) in internal gear (1) convex platform (7), enter another groove (8) then, thereby make camera A member (5) depart from the certain angle of camera B member (3), because the groove (8) that the internal surface of outer tooth ring (2) is provided with is evenly to arrange by circumference, the number of main groove (8) is many more, to depart from the angle number of camera B member (3) just many more for camera A member (5) so, swivel nut (9) overcomes the effect locking locking framework of spring (10), make last tooth (11) engagement of lower tooth (12) with the shaft shoulder (14) of outer tooth ring (2), camera A member (5) can not rotate with camera B member (3).
