[0005] A planar thrust adjustment device comprises an upper push member and a lower push member arranged in an upper and lower manner, wherein opposite sides of the upper push member and the lower push member are respectively integrally formed with a plurality of slope-shaped protrusions;

[0006] When the inclined surfaces of the upper and lower protrusions completely overlap, the distance between the upper push member and the lower push member is the minimum. When the inclined surfaces of the upper and lower protrusions gradually stagger along the upward slope, the distance between the upper push member and the lower push member increases accordingly.

[0007] A groove is provided on the outer circumferential surface of the push-down member, a shift rod is horizontally inserted in the groove, and one end of the shift rod extending out of the groove is connected to a driving mechanism for driving the shift rod to move linearly.

[0008] Furthermore, the sidewall of the groove facing the opening thereof and the opening of the groove are both arc-shaped;

[0009] The shift lever comprises a round handle and a rod body integrally formed with the round handle. One end of the rod body away from the round handle extends out of the groove, and the side portion of the connection between the rod body and the round handle is an arc surface.

[0010] Furthermore, the driving mechanism includes a shift block fixed to one end of the rod body away from the round handle, a screw rod is threadedly connected to the shift block, and a knob for driving the screw rod to rotate is installed at the end of the screw rod.

[0011] A photography kit includes a planar thrust platform, wherein the planar thrust platform adopts the planar thrust adjustment device described above;

[0012] The planar thrust pan / tilt head comprises a pan / tilt head base having an accommodating cavity, wherein the top chamber of the accommodating cavity is in the shape of a truncated cone with a smaller top and a larger bottom, and a ball seat adapted to the shape of the top chamber of the accommodating cavity is installed in the accommodating cavity, and the ball seat is inserted above the push-up member;

[0013] A sphere is clamped in the ball seat, a connecting piece is integrally formed on the surface of the sphere, and one end of the connecting piece away from the sphere is threadedly connected to a clamping seat.

[0014] Furthermore, along the height direction of the gimbal base, a limiting groove connected to the accommodating cavity is opened on the inner wall of the gimbal base, and the outer circumferential surface of the push-up member is integrally formed with a limiting block that cooperates with the limiting groove to limit the rotation of the push-up member.

[0015] Furthermore, a pan / tilt base plate is fixedly connected to the bottom of the pan / tilt base for closing the bottom opening of the accommodating cavity, and a rotating shaft is fixedly connected to the center of the pan / tilt base plate;

[0016] A boss is integrally formed on the bottom of the push-down member. The boss is inserted downward into the rotating shaft, and a rubber elastic body is installed between the bottom of the boss and the rotating shaft.

[0017] Furthermore, the ball seat has an escape opening for the connecting member to swing and adjust the angle of the clamp seat; the ball seat has an opening, so that the ball seat does not form a closed loop.

The magnitude of the thrust can be controlled or adjusted by the driving mechanism driving the lever to rotate the push-down member to an angle.

[0024] 2. When the screw rod is rotated by turning the knob, the rotation of the screw rod can drive the shift block to move along the length direction of the screw rod, thereby driving the shift rod to move. When the shift rod moves linearly, it can shift the push-down member to rotate a certain angle. By controlling the driving mechanism to drive the shift rod to shift the push-down member to rotate the angle, the distance that the push-down member pushes the upper member to move is controlled, thereby controlling or adjusting the locking force generated on the ball when the ball seat is pushed to move and abut against the pan / tilt base.

[0025] Through the action of two mechanical structures, the rotational energy is converted into a huge planar thrust to lock the sphere. This unique secondary torque transmission and adjustment method makes the operation process lighter, smoother and more dense. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and are not intended to limit the present invention.

[0041] In the description of this application, the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0042] See also Figure 1 and Figure 2 The utility model provides a technical solution: a planar thrust adjustment device, comprising an upper push member 1 and a lower push member 2 arranged in an upper and lower manner, wherein the upper push member 1 and the lower push member 2 are cylindrical as a whole, and a plurality of slope-shaped protrusions 3 are integrally formed on opposite sides of the upper push member 1 and the lower push member 2;

[0043] When the inclined surfaces of the upper and lower protrusions 3 completely overlap, the distance between the upper push member 1 and the lower push member 2 is the minimum; when the inclined surfaces of the upper and lower protrusions 3 gradually stagger along the upward slope, the distance between the upper push member 1 and the lower push member 2 becomes larger; when the bottom of the slope of the upper protrusion 3 abuts the top of the lower protrusion 3, the distance between the upper push member 1 and the lower push member 2 reaches the maximum;

[0044] A groove 4 is provided on the outer circumferential surface of the push-down member 2, and a shift rod 5 is horizontally inserted in the groove 4. One end of the shift rod 5 extending out of the groove 4 is connected to a driving mechanism 6 for driving the shift rod 5 to move linearly. The shift rod 5 is driven to move linearly by the driving mechanism 6, and when the shift rod 5 moves, the push-down member 2 can be rotated to a certain angle.

[0045] See also Figure 2 The side wall of the groove 4 facing its opening and the opening of the groove 4 are both arc-shaped. The lever 5 includes a round handle 51 and a rod body 52 integrally formed with the round handle 51. The side portion of the connection between the rod body 52 and the round handle 51 is a curved surface 53. The curved surface 53 cooperates with the arc-shaped opening of the groove 4 to provide more space for the movement of the lever 5 within the range of linear motion of the lever 5 and reduce interference. The round handle 51 can reduce the friction between the lever 5 and the groove 4, making it lighter and smoother during use.

[0046] See also Figure 1 When the inclined surfaces of the upper and lower protrusions 3 partially overlap or completely overlap, the push-down member 2 rotates so that the protrusion 3 located below can move along the inclined surface of the protrusion 3 located above in the uphill direction, and the inclined surfaces of the upper and lower protrusions 3 gradually stagger along the upward slope direction, and the distance between the upper push-up member 1 and the lower push-down member 2 becomes larger, thereby generating an upward thrust on the vertical plane. The magnitude of this thrust can be controlled or adjusted by the driving mechanism 6 to drive the lever 5 to rotate the push-down member 2 to an angle.

[0047] See also Figure 1 and Figure 2 The driving mechanism 6 includes a shift block 61 fixed to the end of the rod body 52 away from the round handle 51. The shift block 61 is threadedly connected to a screw rod 62. The end of the screw rod 62 is screwed with a knob 63 for driving the screw rod 62 to rotate. Specifically, when the screw rod 62 is rotated by rotating the knob 63, the rotation of the screw rod 62 can drive the shift block 61 to move along the length direction of the screw rod 62, thereby driving the shift rod 5 to move linearly and rotate the push-down member 2. The drive of the screw rod 62 drives the protrusion 3 to push the push-up member 1, which is conducive to finely controlling or adjusting the magnitude of the thrust.

[0048] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 9 The present invention also provides a technical solution: a photographic kit, including a plane thrust pan-tilt head 7, and also including the plane thrust adjustment device as described above, the plane thrust pan-tilt head 7 includes a pan-tilt head base 71 with an accommodating cavity 72, the top chamber of the accommodating cavity 72 is in the shape of a truncated cone with a small upper part and a large lower part, a ball seat 73 that is adapted to the shape of the top chamber of the accommodating cavity 72 is installed in the accommodating cavity 72, the ball seat 73 is inserted above the push-up member 1, a sphere 74 is clamped in the ball seat 73, and a connecting member 75 is integrally formed on the surface of the sphere 74, and a clamping seat 76 is threadedly connected to the end of the connecting member 75 away from the sphere 74. Specifically, the ball seat 73 is made of plastic and has an escape hole 731 for the connecting member 75 to swing and adjust the angle of the clamping seat 76. When the connecting member 75 is engaged with the escape hole 731, the connecting member 75 is in a horizontal state, allowing the angle of the clamping seat 76 to be adjusted over a wider range. The ball seat 73 has an opening 732 and does not form a closed loop, so that the ball seat 73, under the pressure of the pan / tilt base 71, surrounds, squeezes and locks the ball 74, thereby fixing the angle of the clamping seat 76.

[0049] See also Figure 4 The cam 73 is pressed against the top of the cam 74 and the cam 76 is pressed against the top of the cam 74 to stop the cam 74 from rotating.

[0050] See also Figures 3 to 5 The bottom screw of the pan-tilt base 71 is fixedly connected to a pan-tilt base plate 79 for closing the bottom opening of the accommodating cavity 72. The center of the pan-tilt base plate 79 is fixedly connected to a rotating shaft 80. The rotating shaft 80 provides an installation position for the installation of the push-down member 2. The top of the rotating shaft 80 is provided with a planar thrust bearing 85 to reduce the friction between the push-down member 2 and the rotating shaft 80, and at the same time make the rotation movement of the push-down member 2 smoother.

[0051] See also Figure 8The bottom of the push-down member 2 is integrally formed with a boss 81, and the top of the rotating shaft 80 is provided with a circular groove. The boss 81 is inserted downward into the groove at the top of the rotating shaft 80, and a rubber elastic body 82 is installed between the bottom of the boss 81 and the rotating shaft 80. The rubber elastic body 82 is installed in the groove at the top of the rotating shaft 80. Under the force generated by the deformation of the rubber elastic body 82, the ball seat 73 can be pushed upward to abut against the top opening of the accommodating cavity 72 through the cooperation of the upper and lower push-ups, thereby providing a pre-tightening force for the ball seat 73 to enclose and lock the ball 74.

[0052] See also Figure 3 and Figure 7 The outside of the pan / tilt base 71 is integrally formed with a mounting tube 83 that is in communication with the interior of the accommodating cavity 72 , and the mounting tube 83 is used to mount the driving mechanism 6 ;

[0053] A stop ring 84 for limiting the movement of the drive mechanism 6 is threadedly connected in the outward opening of the mounting tube 83. The screw rod 62 passes through the stop ring 84 and extends into the mounting tube 83. The stop ring 84 is used to block and limit the screw rod 62 to prevent the screw rod 62 from axial movement and ensure the stability of the installation of the screw rod 62.

[0054] The working principle of the utility model: The initial state of the utility model is as follows: Figure 4 As shown (the sphere 74 is not locked, and the clamp seat 76 can be freely moved to adjust the angle), at this time, the distance between the upper push member 1 and the lower push member 2 is the minimum, and when the screw rod 62 is rotated clockwise by the knob 63, the rotation of the screw rod 62 can drive the shift block 61 to move along the length direction of the screw rod 62, thereby driving the shift rod 5 to move, and the shift rod 5 can shift the lower push member 2 to rotate a certain angle when it moves linearly;

[0055] When the push-down member 2 rotates to cause the protrusion 3 below to move in the uphill direction along the inclined surface of the protrusion 3 located above, the inclined surfaces of the upper and lower protrusions 3 gradually stagger along the upward slope, and the distance between the push-up member 1 and the push-down member 2 becomes larger, thereby generating an upward thrust in the vertical plane to push the ball seat 73 and drive the ball 74 to move toward the top opening of the accommodating cavity 72, so that the ball seat 73 is squeezed and locked to the ball 74 under the pressure of the pan / tilt base 71, and the angle of the clamp seat 76 is fixed. Finally, the locking state is as shown Figure 6 As shown;

[0056] By controlling the driving mechanism 6 to drive the lever 5 to move the downward push member 2 to rotate, and then controlling the distance that the downward push member 2 pushes the upward push member 1 to move, the locking force generated on the sphere 74 when the ball seat 73 is pushed to move and abut against the pan-tilt base 71 is controlled or adjusted. When it is necessary to loosen the sphere 74 to adjust the angle of the clamp seat 76, just turn the knob 63 in the opposite direction.

[0057] See also Figure 10 The utility model also provides another technical solution: a photography kit, including a plane thrust horizontal adjustment seat 8, which can be installed with a plane thrust adjustment device as described above in a similar arrangement to the plane thrust pan head 7. The plane thrust adjustment device pushes the ball bowl upward to quickly adjust the locking force between the ball bowl and the hemisphere in the plane thrust horizontal adjustment seat 8.

[0058] See also Figure 11 The utility model also provides another technical solution: a photography kit, including a plane thrust hemispherical head 9, which can be installed with a plane thrust adjustment device as described above in a similar arrangement to the plane thrust head 7. The plane thrust adjustment device pushes the ball bowl upward to quickly adjust the locking force between the ball bowl and the hemisphere in the plane thrust hemispherical head 9.

[0059] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
