Description

Technical Field

[0001] The present invention relates to the technical field of pan-tilt locking, and particularly relates to a dual-mode pan-tilt adjusting device and a photography kit. Background Art

[0002] Traditional spherical pan-tilts are widely used in the field of photography due to their lightweight design and flexible adjustment characteristics. The locking mechanism of spherical pan-tilts generally uses a screw to extrude the sphere or drives a control device through a screw to extrude the pan-tilt sphere to complete the locking of the pan-tilt sphere. However, after a long time of use, play will occur in the cooperation between parts, and the initial position of the pan-tilt locking will drift. When the knob is unlocked and returns to the starting point, the pan-tilt sphere will lose damping force and shake, and the knob will rotate idly when tightened, seriously affecting the user experience. Therefore, how to design an adjusting device that can both adjust the locking starting position (to avoid the knob rotating idly) and set the initial damping force is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a dual-mode pan-tilt adjusting device and a photography kit to solve the technical problem that the locking starting point drifts due to play in parts during the use of the pan-tilt as described in the background art and cannot be reset.

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

[0005] A dual-mode pan-tilt adjusting device includes a screw and a control device screwed outside the screw. One end of the screw is fixedly connected with a fixed limiter for restricting the starting position of the control device. It also includes a main knob for controlling the rotation of the screw, and a secondary knob is threadedly connected to the end of the screw away from the fixed limiter;

[0006] When the secondary knob rotates under the action of an external force, it is converted into a displacement movement of the screw along the axial direction of the main knob through threaded cooperation with the screw to adjust the starting position of the control device.

[0007] Further, a through hole extending axially is provided inside the main knob, and a limiting groove is opened on the inner wall of the through hole. A limiting structure is provided on the secondary knob for cooperating with the limiting groove to limit the axial movement stroke of the secondary knob.

[0008] Further, the secondary knob includes a connecting portion threadedly connected to the screw, and an operating portion is integrally formed on the outer side of the connecting portion;

[0009] A side groove is formed on the outer surface of the connecting portion. The limiting structure includes a limiting buckle inserted into the side groove. An elastic member A is installed between the limiting buckle and the side groove. The limiting buckle extends into the limiting groove under the action of the force generated by the elastic member A to limit the axial movement stroke of the secondary knob.

[0010] Further, the side groove includes an arc-shaped groove and mounting holes located at both ends of the arc-shaped groove and communicating with the arc-shaped groove;

[0011] The limiting buckle includes an arc-shaped portion adapted to the shape of the arc-shaped groove. At both ends of the arc-shaped portion, columns adapted to the shape of the mounting holes are integrally formed. The elastic member A is installed between the columns and the bottom wall of the mounting hole.

[0012] Further, the middle part of the screw rod is a limiting portion. A rotating limiting block is fixedly connected inside the main knob. The screw rod is inserted through the rotating limiting block. The shape of the through hole of the rotating limiting block matches the cross-sectional shape of the limiting portion.

[0013] Further, an end groove is formed on one side of the secondary knob facing the rotating limiting block, and an elastic member B is installed in the end groove.

[0014] Further, a fixing screw for adjusting the installation of the device is inserted through the main knob. The fixing screw is hollow and sleeved outside the screw rod. The main knob is only allowed to perform circumferential movement under the limitation of the fixing screw and the rotating limiting block.

[0015] A photography kit includes a photographic and video camera pan-tilt head. The photographic and video camera pan-tilt head adopts the dual-mode pan-tilt head adjusting device as described above. The photographic and video camera pan-tilt head includes a pan-tilt head base. A threaded hole is formed on the side of the pan-tilt head base. The fixing screw is threadedly connected to the threaded hole.

[0016] A photography kit includes a spherical pan-tilt head. The spherical pan-tilt head adopts the dual-mode pan-tilt head adjusting device as described above.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By using the screw rod structure with an integrated through design, the fixed limiter and the secondary knob (movable limiter) are respectively arranged at both ends of the screw rod. By screwing the secondary knob (movable limiter) to adjust and change the starting position of the control device, the technical problem that the locking starting point drifts due to the looseness of parts during the use of the pan-tilt head and the locking starting point cannot be reset is solved.

[0019] 2. The secondary knob is used for the settings before using the pan-tilt. When the main knob is turned counterclockwise to the end (the control device returns to the initial position), by screwing the secondary knob, the axial offset of the screw system can be adjusted to compensate for the drift of the initial position caused by looseness during the use of the pan-tilt, and thus the initial locking position of the pan-tilt can be reset and the initial damping force of the pan-tilt can be set.

[0020] 3. The main knob is used for the locking (unlocking) control during the use of the pan-tilt, and the locking force can be arbitrarily adjusted within the range of the initial damping force set by the secondary knob and the locking force of the pan-tilt sphere;

[0021] By screwing the main knob to control the circumferential rotation of the screw, the control device will perform an axial displacement on the screw, and when the control device performs an axial displacement, the pan-tilt sphere will be locked or unlocked. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] Typical implementation manners reflecting the features and advantages of the present invention will be specifically described in the following description. It should be understood that the present invention can have various changes in different implementation manners, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0035] In the description of the present application, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application.

[0036] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a dual-mode cloud platform adjusting device, including a screw 1 and a control device 2 screwed outside the screw 1. When the screw 1 rotates, the axial position of the control device 2 on the screw 1 can be adjusted. One end of the screw 1 is fixedly connected with a fixed limiter 3 through a thread, which is used to limit the starting position of the control device 2;

[0037] It further includes a main knob 4 for controlling the rotation of the screw 1. A fixing screw 13 for installing the adjusting device is inserted through the main knob 4. The fixing screw 13 is hollow and sleeved outside the screw 1. When the main knob 4 is installed on the cloud platform through the fixing screw 13, the main knob 4 only performs circumferential movement under the limitation of the fixing screw 13 and the rotation limiting block 9, so as to effectively control the rotation of the screw 1 and adjust the position of the control device 2.

[0038] Please refer to Figures 2 to 5, a through hole 41 extending axially is provided inside the main knob 4, a ring-shaped limiting groove 42 is formed on the inner wall of the through hole 41, one end of the screw rod 1 away from the fixed limiter 3 is threadedly connected with a secondary knob 5, the secondary knob 5 includes a connecting portion 51 threadedly connected with the screw rod 1, an operating portion 52 is integrally formed on the outer side of the connecting portion 51, and a limiting structure for cooperating with the limiting groove 42 to limit the axial movement stroke of the secondary knob 5 is provided on the connecting portion 51;

[0039] Please refer to Figure 2 and Figure 5 , a side groove 53 is formed on the outer surface of the connecting portion 51, the limiting structure includes a limiting buckle 7 inserted into the side groove 53, an elastic member A8 is installed between the limiting buckle 7 and the side groove 53, the elastic member A8 adopts a spring or other elastic structures in the prior art that can achieve the same purpose, and the limiting buckle 7 extends into the limiting groove 42 under the action of the force generated by the elastic member A8 to limit the axial movement stroke of the secondary knob 5;

[0040] Please refer to Figure 5 , the side groove 53 includes an arc groove 531 and mounting holes 532 located at both ends of the arc groove 531 and communicating with the arc groove 531; the limiting buckle 7 includes an arc portion 71 adapted to the shape of the arc groove 531, and columns 72 adapted to the shape of the mounting holes 532 are integrally formed at both ends of the arc portion 71, and the elastic member A8 is installed between the columns 72 and the bottom wall of the mounting hole 532.

[0041] Please refer to Figure 3 and Figure 4 , the middle part of the screw rod 1 is a limiting portion 101, the cross section of the limiting portion 101 is of a polygonal structure, a rotating limiting block 9 is fixedly connected inside the main knob 4 by screws, the screw rod 1 is inserted through the rotating limiting block 9, the through hole of the rotating limiting block 9 is of a polygonal hole shape, and its cross-sectional shape coincides with the cross-sectional shape of the limiting portion 101. When the main knob 4 rotates, the screw rod 1 can be driven to rotate synchronously through the cooperation of the rotating limiting block 9 and the limiting portion 101, and when the screw rod 1 is subjected to an axial external force, it can move axially relative to the main knob 4.

[0042] When the operating portion 52 rotates under the action of an external force, since the limiting buckle 7 extends into the limiting groove 42 under the action of the elastic member A8 to limit the axial movement stroke of the secondary knob 5, at this time, the threaded cooperation between the connecting portion 51 and the screw rod 1 is converted into the axial displacement movement of the screw rod 1 along the main knob 4, thereby driving the fixed limiter 3 and the control device 2 to move axially as a whole, and adjusting the starting position of the control device 2.

[0043] Specifically, when the main knob 4 is rotated counterclockwise to the end (it cannot be turned further), the fixed limiter 3 limits the control device 2, and the control device 2 returns to the starting position. At this time, when the secondary knob 5 is rotated clockwise, the screw 1 can be pulled outwards, and the distance between the fixed limiter 3 and the secondary knob 5 is reduced. When the secondary knob 5 is rotated counterclockwise, the distance between the fixed limiter 3 and the secondary knob 5 is increased. In this way, the starting position of the control device 2 can be changed, and the slack generated after the use of the pan-tilt can be eliminated.

[0044] Please refer to Figure 3 and Figure 5 , on one side of the secondary knob 5 facing the rotation limiter 9, an end groove 10 is provided, and an elastic member B11 is installed in the end groove 10. The elastic member B11 is made of a nitrile rubber ring or other elastic structures in the prior art that can achieve the same purpose. The elastic member B11 is used to generate an outward axial force, so as to play a certain buffering role, making the feel of turning the secondary knob 5 softer and smoother. And by selecting elastic members B11 with different elastic forces, the initial damping force of the secondary knob 5 can be adjusted and set. A gasket 12 is installed between the elastic member B11 and the groove wall of the end groove 10, and the friction between the secondary knob 5 and the elastic member B11 during the rotation of the secondary knob 5 can be reduced through the gasket 12, so that the rotation process of the secondary knob 5 is smoother.

[0045] Please refer to Figure 6 and Figure 7 , a photography kit, including a photographic camera pan-tilt 14, the photographic camera pan-tilt 14 adopts the dual-mode pan-tilt adjustment device as described above. The photographic camera pan-tilt 14 includes a pan-tilt base 141, and a threaded hole 142 is provided on the side of the pan-tilt base 141. The fixing screw 13 is threadedly connected to the threaded hole 142.

[0046] By rotating the main knob 4 to drive the control device 2 back to the starting position (unlock), and finally rotating the secondary knob 5 to adjust the starting position of the control device 2, compensating for the drift of the initial position caused by slack during the use of the pan-tilt, and then resetting the initial locking position and the initial damping force of the control device 2 on the pan-tilt sphere 144. Subsequently, when the control device 2 moves under the control of the main knob 4, it can push the ball bowl 143 to abut against the pan-tilt sphere 144 for locking or unlocking.

[0047] A nylon gasket 6 is installed between the main knob 4 and the pan-tilt base 141 to reduce the friction during the rotation of the main knob 4 and improve the operating feel.

[0048] Please refer to Figures 8 to 11, a photographic kit, comprising a spherical pan head 15, wherein the spherical pan head 15 adopts the dual-mode pan head adjustment device as described above, and the dual-mode pan head adjustment device is installed on the spherical pan head 15 in a manner similar to the manner in which it is installed on the photographic and videography pan head 14, except that the locking of the pan head ball 144 adopts indirect drive locking, and the locking method of the pan head ball 144 adopts the plane thrust locking method in the Chinese patent document with publication number CN119467982A. When the screw 1 rotates under the control of the main knob 4, the control device 2 moves along the axial direction of the screw 1, and during the movement, the push-down member 152 is driven to rotate horizontally, and when the push-down member 152 rotates horizontally, the push-down member 152 is locked or unlocked by rotating the upper push-up member 151 with the inclined surface of the protrusion 153 between the upper and lower push-down members. The specific principle is the prior art and will not be described in detail here.

[0049] 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.
