[0001] The present invention relates to the technical field of photography auxiliary equipment, and in particular to a plane thrust adjustment device and a photography kit. Background Art

[0002] The gimbal is the most commonly used auxiliary shooting equipment in photographic equipment, and is mainly used to assist in adjusting the shooting angle of the camera. The existing spherical gimbal is locked by mostly tightening a screw to press the concave position on the upper part of the ball seat, driving the ball seat to push the ball upward to lock it. This adjustment method requires the user to use a large force to twist the screw, and the operation process is relatively stiff and the user experience is very general. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a planar thrust adjustment device to solve the technical problem that the spherical head in the prior art needs the user to use a large force to tighten the screw to push the ball seat when locking the ball, and the operation process feels hard and the user experience is poor.

[0004] The present invention is achieved through the following technical solutions:

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

[0006] When the inclined surfaces of the upper and lower protrusions completely overlap, the distance between the upper push piece and the lower push piece is the minimum, and when the inclined surfaces of the upper and lower protrusions gradually stagger along the upward slope direction, the distance between the upper push piece and the lower push piece 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 side wall of the groove facing its opening and the opening of the groove are both arc-shaped;

[0009] The 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 comprises a shifting block fixedly arranged at one end of the rod body away from the round handle, a screw rod is threadedly connected to the shifting block, and a knob for driving the screw rod to rotate is installed at the end of the screw rod.

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

[0012] The planar thrust pan / tilt head comprises a pan / tilt head base with an accommodating cavity, the top chamber of the accommodating cavity is in the shape of a truncated cone with a small top and a large bottom, a ball seat matching the shape of the top chamber of the accommodating cavity is installed in the accommodating cavity, and the ball seat is inserted above the upper push piece;

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

[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 a limiting block is integrally formed on the outer circumferential surface of the push-up member to cooperate with the limiting groove to limit the rotation of the push-up member.

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

[0016] A boss is integrally formed at 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.

[0018] Furthermore, a mounting tube is integrally formed on the outside of the pan / tilt base and communicates with the interior of the accommodating cavity, and the mounting tube is used to mount the driving mechanism;

[0022] The beneficial effects of the present invention are:

[0023] 1. When the inclined surfaces of the upper and lower protrusions partially overlap or completely overlap, the push-down member rotates to cause the protrusion located below to move along the inclined surface of the upper protrusion in the uphill direction, and the inclined surfaces of the upper and lower protrusions gradually stagger along the uphill direction, and the distance between the upper push-up member and the lower push-down member increases accordingly, thereby generating an upward thrust on the vertical plane. The magnitude of the thrust can be controlled or adjusted by the driving mechanism driving the lever to move the push-down member to rotate at 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 an 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 changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0041] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present 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, and therefore should not be understood as a limitation on the present application.

[0042] See also Figure 1 and Figure 2 The present invention provides a technical solution: a planar thrust adjustment device, comprising an upper push piece 1 and a lower push piece 2 arranged up and down, the upper push piece 1 and the lower push piece 2 are cylindrical as a whole, and the upper push piece 1 and the lower push piece 2 are respectively integrally formed with a plurality of slope-shaped protrusions 3 on opposite sides thereof;

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

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

[0045] See also Figure 2 The side wall of the groove 4 facing the opening thereof 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 an arc surface 53. The arc surface 53 cooperates with the arc-shaped opening of the groove 4, which can provide more activity space for the lever 5 within the range of the 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 increases accordingly, thereby generating an upward thrust in the vertical plane. The magnitude of the 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 shifting block 61 fixed to one end of the rod body 52 away from the round handle 51, and a screw rod 62 is threadedly connected to the shifting block 61. A knob 63 for driving the screw rod 62 to rotate is installed at the end of the screw rod 62 through a screw. Specifically, when the screw rod 62 is rotated by the knob 63, the screw rod 62 rotates to drive the shifting block 61 to move along the length direction of the screw rod 62, thereby driving the shifting rod 5 to move linearly to shift the push-down member 2 to rotate, and the protrusion 3 is driven to push the push-up member 1 by the screw rod 62, which is conducive to fine control or adjustment of the thrust.

[0048] See also Figure 3 , Figure 4 , Figure 5 and Fig. 9 The present invention also provides a technical solution: a photographic kit, comprising a plane thrust pan-tilt head 7, and also comprising the plane thrust adjustment device as described above, wherein the plane thrust pan-tilt head 7 comprises a pan-tilt head base 71 having an accommodating cavity 72, the top chamber of the accommodating cavity 72 is in the shape of a truncated cone with a small top and a large bottom, a ball seat 73 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 upper push member 1, a sphere 74 is clamped in the ball seat 73, a connecting member 75 is integrally formed on the surface of the sphere 74, and a clamping seat 76 is threadedly connected to one end of the connecting member 75 away from the sphere 74. Specifically, the ball seat 73 is made of plastic, and the ball seat 73 has an escape opening 731 for the connecting member 75 to swing and adjust the angle of the clamp seat 76. When the connecting member 75 is inserted into the escape opening 731, the connecting member 75 is in a horizontal state, so that the angle of the clamp seat 76 can be adjusted in a wider range; the ball seat 73 has an opening 732, and the ball seat 73 does not form a closed loop, so that the ball seat 73 can enclose, squeeze and lock the ball 74 under the pressure of the pan / tilt base 71, so as to fix the angle of the clamp seat 76;

[0049] See also Figure 4 Along the height direction of the pan-tilt base 71, a limiting groove 77 connected to the accommodating cavity 72 is opened on the inner wall of the pan-tilt base 71, and a limiting block 78 is integrally formed on the outer circumferential surface of the upper push member 1 to cooperate with the limiting groove 77 to limit the rotation of the upper push member 1, so that the upper push member 1 only moves up and down under the action of the lower push member 2, and does not rotate, thereby ensuring that the ball seat 73 is pushed upward to move, and the ball seat 73 is squeezed and locked to enclose the ball 74 under the opening at the top of the accommodating cavity 72.

[0050] See also Figures 3 to 5 The bottom screw of the gimbal base 71 is fixedly connected with a gimbal bottom plate 79 for closing the bottom opening of the accommodating cavity 72. The center of the gimbal bottom plate 79 is fixedly connected with 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 8A boss 81 is integrally formed at the bottom of the push-down member 2, and a circular groove is opened at the top of the rotating shaft 80. The boss 81 is downwardly inserted 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-down members, 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 pan / tilt base 71 is integrally formed with a mounting tube 83 which 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, thereby ensuring the stability of the installation of the screw rod 62.

[0054] Working principle of the present invention: The initial state of the present invention is as follows Figure 4 As shown (the ball 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 of 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 direction, 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 to drive the ball 74 to move toward the top opening of the accommodating cavity 72, so that the ball seat 73 surrounds, squeezes and locks the ball 74 under the pressure of the pan / tilt base 71, fixes the angle of the clamp seat 76, and finally the locking state is as shown in FIG. 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, it is possible to control or adjust the locking force exerted on the sphere 74 when the ball seat 73 is pushed to move and abut against the pan-tilt base 71. When it is necessary to loosen the sphere 74 to adjust the angle of the clamp seat 76, simply turn the knob 63 instead.

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

[0058] See also Fig.11 The present invention 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, and the ball bowl is pushed upward by the plane thrust adjustment device to quickly adjust the locking force between the ball bowl and the hemispherical body 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 substitutions made by technicians in this field on the basis of the present invention are within the scope of protection required by the present invention.
