These devices are usually connected and installed with a mini gimbal in the existing technology, such as a snail gimbal, and the angle of the auxiliary shooting equipment is then adjusted through the snail gimbal.

[0003] When adjusting the angle of the auxiliary shooting equipment, the snail head in the prior art mostly controls the rotation of the shaft on the base of the head by screwing the screws, so as to achieve the purpose of adjusting the installation angle of the equipment. However, the steps of screwing the screws one by one are cumbersome, which is not only troublesome to operate, but also requires a lot of force to tighten the screws, resulting in a poor user experience. Secondly, the locking effect of the screws is difficult to control. If they are too loose, the locking is not firm, and if they are too tight, it is not conducive to the adjustment work. Summary of the invention

[0010] A first elastic member is installed between the first locking member and the second locking member, and is used to push the connecting member and the fixed shift toothed disc to slide relative to each other, thereby providing a thrust for the shift block to be automatically inserted into the shift groove.

[0011] Furthermore, the connecting member is externally threadedly connected to a shift knob, and the movable shift gear plate is inserted into the shift knob.

[0012] Furthermore, a second elastic member is installed between the shift knob and the second locking member, and the second elastic member is sleeved outside the connecting member to provide a thrust when the second locking member is locked with the first locking member.

[0013] Furthermore, the fixed shift toothed disc is composed of three parts, namely a fixing part for fixing with the rotating shaft, a mounting part for mounting the connecting member, and a shifting part for cooperating with the movable shift toothed disc for shifting;

[0014] An inner wall screw is passed through the rotating shaft, and a screw portion of the inner wall screw extends out of the rotating shaft and is threadedly connected to the fixing portion.

[0015] Furthermore, a fixing block is sleeved on the outer side of one end of the inner wall screw extending out of the rotating shaft, and a limiting groove is provided on the side of the fixing block facing the fixing part, and the fixing part extends into the limiting groove to limit the rotation and movement of the fixing block;

[0016] The first locking member is sleeved outside the fixing block, and a notch is formed on a side of the fixing block away from the limiting groove. The inner wall of the first locking member has a protrusion matched with the notch to limit the rotation and movement of the first locking member.

[0017] Furthermore, a first plug hole and a second plug hole are formed at the end of the rotating shaft, and the fixing block and the first locking member are respectively positioned and inserted into the end of the rotating shaft through the first plug hole and the second plug hole;

[0018] An installation slot is provided on the inner wall of the shift knob, and the movable shift gear plate is inserted into the installation slot.

[0019] Furthermore, the pan / tilt base includes a mounting seat and two mounting arms, the two mounting arms are integrally formed with the mounting seat and are arranged opposite to each other on the top of the mounting seat;

[0021] Furthermore, a second through hole in a stepped shape is formed on the other of the mounting arms, a positioning groove is formed on the rotating shaft near the end of the second through hole, and a positioning buckle is inserted into both the second through hole and the positioning groove;

[0022] A gasket is provided between the positioning buckle and the stepped inner wall of the second through hole, and between the mounting arm and the rotating shaft. A connecting screw is installed in the positioning buckle for connecting the rotating shaft and the mounting arm.

[0028] The beneficial effects of the present invention are:

[0029] When the shift-type adjustment device of the present invention is in use, the movable shift gear plate is rotated, and the shift block on the movable shift gear plate moves along the inclined surface of the fixed shift gear plate until it is inserted into the shift groove for shifting. When the shift block is inserted into the shift groove at different positions, the end surface distance between the movable shift gear plate and the fixed shift gear plate changes accordingly. At this time, the push mechanism drives the second locking member to move away from or approach the first locking member accordingly, so as to correspondingly adjust the degree of engagement between the first locking member and the second locking member, thereby controlling whether the rotating shaft can rotate relative to the pan / tilt base. Compared with the prior art of adjusting the tightness between the rotating shaft and the pan / tilt base by screwing a screw, the operation is more convenient and labor-saving.

DETAILED DESCRIPTION

[0044] 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.

[0045] 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.

[0046] See also Figure 1 and Figure 2 The present invention provides a technical solution: a shift-type adjustment device, comprising a pan head base 1 and a rotating shaft 2 rotatably mounted on the pan head base 1, a platform for mounting a photography auxiliary device is arranged on the rotating shaft 2, the pan head base 1 comprises a mounting seat 25 and two mounting arms 26, the two mounting arms 26 are integrally formed with the mounting seat 25, and are relatively arranged on the top of the mounting seat 25, the pan head base 1 is concave as a whole, and a dovetail groove is arranged at the bottom, which is used for the pan head base 1 to be mounted on a camera cage;

[0047] See also Figure 4A first through hole 27 is formed on one of the mounting arms 26, and a positioning protrusion 28 is formed on the inner wall of the first through hole 27. The positioning protrusion 28 extends along the center line direction of the first through hole 27. A second locking member 4 is installed in the first through hole 27, and a positioning groove 29 is formed on the outer circumferential surface of the second locking member 4. The positioning groove 29 is slidably matched with the positioning protrusion 28, thereby limiting the second locking member 4 from rotating along the circumferential direction of the first through hole 27;

[0048] See also Figures 1 to 3 A second through hole 30 in a stepped shape is formed on the other mounting arm 26, a positioning groove 31 is formed on the rotating shaft 2 near the end of the second through hole 30, a positioning buckle 32 is inserted in the second through hole 30 and the positioning groove 31, a gasket 33 is provided between the positioning buckle 32 and the stepped inner wall of the second through hole 30, and between the mounting arm 26 and the rotating shaft 2, and the gasket 33 is made of 1 mm thick nylon gasket, a connecting screw 34 is installed in the positioning buckle 32 for connecting the rotating shaft 2 and the mounting arm 26, and the connecting screw 34 passes through the positioning buckle The positioning buckle 32 is threadedly connected with the rotating shaft 2, and the positioning buckle 32 can be driven to cooperate with the rotating shaft 2 to clamp the mounting arm 26. The damping force between the mounting arm 26 and the rotating shaft 2 can be adjusted by adjusting the tightness of the connecting screw 34. When the positioning buckle 32 is inserted into the positioning slot 31, the positioning buckle 32 will not rotate relative to the rotating shaft 2. When the rotating shaft 2 is rotated, the rotating shaft 2 can drive the positioning buckle 32 and the connecting screw 34 to rotate, thereby ensuring that the damping force is constant. The rotation of the rotating shaft 2 is limited by the positioning buckle 32, which is conducive to screwing the connecting screw 34.

[0049] See also Figure 1 , Figure 4 and Figure 7 A first locking member 3 is installed on the rotating shaft 2. The locking member in the present application document adopts a locking toothed disc, and may also be other plug-in locking limit structures. When the two locking toothed discs are fully engaged and locked, the rotating shaft 2 and the pan / tilt base 1 will not rotate relative to each other. A fixed shift toothed disc 6 is commonly penetrated through the two locking members, and the fixed shift toothed disc 6 is fixed to the rotating shaft 2;

[0050] The fixed shift toothed disc 6 is movably mounted with a movable shift toothed disc 7, the opposite surfaces of the movable shift toothed disc 7 and the fixed shift toothed disc 6 are both inclined surfaces, and the opposite surfaces are respectively provided with at least one shift block 8 and two shift grooves 9, and the fixed shift toothed disc 6 is provided with a pushing mechanism;

[0051] When the shifting adjustment device of the present invention is in use, the movable shifting toothed disc 7 is rotated, and the shifting block 8 on the movable shifting toothed disc 7 moves along the inclined surface of the fixed shifting toothed disc 6 until it is engaged in the shifting groove 9 to shift gears (the engaging position of the shifting block 8 and the shifting groove 9 is the position where the adjustment device realizes shifting). When the shifting block 8 is inserted into the shifting groove 9 at different positions, the end surface distance between the movable shifting toothed disc 7 and the fixed shifting toothed disc 6 changes accordingly, and at this time, the pushing mechanism drives the second locking member 4 to move away from or approach the first locking member 3 accordingly;

[0052] The fixed shift gear plate 6 of the present invention has at least three gear positions:

[0053] First, when the movable shift gear plate 7 is rotated counterclockwise (when a person faces the movable shift gear plate 7) to the leftmost gear position as shown in the attached figure, Figure 1 As shown, at this time, the movable shifting toothed disc 7 is at the smallest distance from the end surface of the fixed shifting toothed disc 6, and the second locking member 4 moves to the farthest distance from the first locking member 3 under the action of the pushing mechanism, and the two achieve zero contact. At this time, the right shifting system does not work, and only the left damping system works normally. The rotating shaft 2 can be rotated at will to adjust the angle of the photography auxiliary equipment, and this gear is a silent gear.

[0054] Secondly, when the movable shift toothed disc 7 rotates clockwise to the middle gear position along the inclined surface of the fixed shift toothed disc 6, the movable shift toothed disc 7 is pushed away from the fixed shift toothed disc 6 in the opposite direction, and the end surface distance between the movable shift toothed disc 7 and the fixed shift toothed disc 6 increases. At this time, the second locking member 4 is pushed to a semi-engaged state with the first locking member 3. Since the first locking member 3 is fixed and the second locking member 4 is movably arranged, when the rotating shaft 2 is rotated, the first locking member 3 will reciprocally squeeze the second locking member 4, and the second locking member 4 will be reset under the action of the pushing mechanism, so that the second locking member 4 and the first locking member 3 are constantly approaching and retreating. In this process, the continuous mutual engagement produces a "click-click-click" toothed disc friction sound, thereby producing a mechanical feel and improving the user's experience.

[0055] Thirdly, when the movable shift toothed disc 7 rotates clockwise from the middle gear position, the shift block 8 moves along the inclined surface of the fixed shift toothed disc 6, so that the end surface distance of the movable shift toothed disc 7 from the fixed shift toothed disc 6 gradually increases again, and drives the second locking member 4 to fully engage with the first locking member 3, thereby reaching a locked state, at which time the rotating shaft 2 cannot rotate relative to the pan / tilt base 1;

[0056] Compared with the prior art method of adjusting the tightness between the rotating shaft 2 and the pan-tilt base 1 by screwing the screw, the shift-type adjustment device of the present invention adopts a progressive and progressive gear adjustment method. It only needs to rotate the movable shift toothed disc 7 to insert the shift block 8 into different shift grooves 9 for shifting, so as to adjust the degree of engagement of the first locking member 3 and the second locking member 4, thereby controlling whether the rotating shaft 2 can rotate relative to the pan-tilt base 1, and the operation is more convenient and labor-saving. Secondly, the present invention adopts a toothed disc biting method to lock the rotating shaft 2 and the pan-tilt base 1, and the locking method is more secure. The setting of the gear position can allow the user to clearly know the engagement status of the first locking member 3 and the second locking member 4, thereby knowing the locking status of the rotating shaft 2 and the pan-tilt base 1, which solves the technical problems in the prior art that the mini pan-tilt is laborious when locking with screws and the locking effect is difficult to control.

[0057] See also Figure 1 and Figure 4 The pushing mechanism includes a connecting member 10 movably mounted on the fixed shift gear plate 6, the connecting member 10 is sleeve-shaped, and an external thread is provided on its outer surface, and the second locking member 4 is movably mounted on the outside of the connecting member 10;

[0058] See also Figure 1 , Figure 4 , Figure 6 and Figure 7 A first elastic member 11 is installed between the first locking member 3 and the second locking member 4. The first elastic member 11 is a spring, which is sleeved outside the fixed shift toothed disc 6 and installed in the connecting member 10. The first elastic member 11 is used to push the connecting member 10 and the fixed shift toothed disc 6 to slide relative to each other, so as to provide thrust for the shift block 8 to automatically insert into the shift groove 9;

[0059] The connecting member 10 is externally threadedly connected to a shift knob 12, an installation slot 24 is provided on the inner wall of the shift knob 12, an insertion rod is installed behind the movable shift gear plate 7, and the movable shift gear plate 7 is inserted into the installation slot 24 through the insertion rod to limit the relative rotation between the movable shift gear plate 7 and the shift knob 12;

[0060] A second elastic member 13 is installed between the shift knob 12 and the second locking member 4. The second elastic member 13 is a nitrile O-ring. The second elastic member 13 is sleeved outside the connecting member 10 to provide thrust when the second locking member 4 is locked with the first locking member 3.

[0061] When the gear shifting operation is performed, the gear shifting knob 12 is turned, and the gear shifting knob 12 drives the movable gear shifting tooth plate 7 to rotate synchronously. At this time, the gear shifting block 8 moves along the inclined surface of the fixed gear shifting tooth plate 6 until the gear shifting block 8 is aligned with the gear shifting groove 9. When the gear shifting block 8 is aligned with the gear shifting groove 9, the first elastic member 11 is deformed to push the connecting member 10 to move along the fixed gear shifting tooth plate 6, thereby driving the gear shifting block 8 to insert into the gear shifting groove 9. At the same time, since the first elastic member 11 pushes the connecting member 10 to move, the connecting member 10 drives the second locking member 4 to move when it moves, thereby changing the bite state of the second locking member 4 and the first locking member 3, so as to achieve the purpose of gear shifting.

[0062] Secondly, when the second locking member 4 is in a semi-engaged state with the first locking member 3, rotating the rotating shaft 2 will drive the first locking member 3 to rotate synchronously, and the second locking member 4 is restricted from rotating under the cooperation of the positioning protrusion 28 and the positioning groove 29, so that when the first locking member 3 rotates, it can squeeze and push the second locking member 4 to slide, and when the second locking member 4 slides, it squeezes the second elastic member 13, and the deformation of the second elastic member 13 can drive the second locking member 4 to enter a semi-engaged state with the first locking member 3 again, and then in the process of rotating the rotating shaft 2, the second locking member 4 and the first locking member 3 are constantly approaching and retreating, and in this process, they are constantly biting each other to produce a "click-click-click" toothed disc friction sound, thereby producing a mechanical feel and improving the user's experience;

[0063] Finally, when the second locking member 4 is fully engaged and locked with the first locking member 3, the second elastic member 13 is squeezed between the shift knob 12 and the second locking member 4, and the elastic force is generated by the deformation of the second elastic member 13, thereby providing a thrust for the second locking member 4 to be locked with the first locking member 3, thereby ensuring the locked state.

[0064] See also Figure 1 , Figure 5 and Figure 6 The fixed shift toothed disc 6 is composed of three parts, namely a fixing part 14 for fixing to the rotating shaft 2, a mounting part 15 for mounting the connecting member 10, and a shifting part 16 for cooperating with the movable shift toothed disc 7 for shifting;

[0065] An inner wall screw 17 is inserted into the rotating shaft 2, and the screw portion of the inner wall screw 17 extends out of the rotating shaft 2 and is threadedly connected to the threaded hole at the end of the fixing portion 14;

[0066] A fixing block 18 is sleeved on the outer side of one end of the inner wall screw 17 extending out of the rotating shaft 2, and a limiting groove 19 is provided on the side of the fixing block 18 facing the fixing portion 14. The limiting groove 19 is a waist-shaped groove. When the inner wall screw 17 is threadedly connected with the fixing portion 14, the fixing portion 14 extends into the limiting groove 19, which can limit the rotation and movement of the fixing block 18.

[0067] The first locking member 3 is sleeved outside the fixing block 18, and a notch 20 is formed on a side of the fixing block 18 away from the limiting groove 19. The inner wall of the first locking member 3 has a protrusion 21 that cooperates with the notch 20. The notch 20 and the protrusion 21 cooperate to limit the first locking member 3 from rotating and moving forward. When the inner wall screw 17 is threadedly connected to the fixed shifting gear plate 6, the fixing block 18 and the first locking member 3 can be connected as a whole, and the first locking member 3 can be fixed to the end of the rotating shaft 2, thereby simplifying the structure of the present invention and making the structure of the present invention more compact.

[0068] See also Figure 5 A first plug hole 22 and a second plug hole 23 are provided at the end of the rotating shaft 2, and the fixing block 18 and the first locking member 3 are respectively positioned and inserted into the end of the rotating shaft 2 through the first plug hole 22 and the second plug hole 23, and can further limit the rotation of the fixing block 18 and the first locking member 3.

[0069] See also Figure 8 The present invention also provides a technical solution. In the first embodiment, a photographic kit includes a double-head shifting platform 35. The double-head shifting platform 35 adopts the shifting adjustment device described above. Both heads of the double-head shifting platform 35 can be used for installation and used in conjunction with a stabilizer or a camera tripod, and the compatibility is stronger.

[0070] See also Fig. 9 , Embodiment 2, a photographic kit of the present invention comprises a single-head shifting platform 36, wherein the single-head shifting platform 36 adopts the shifting adjustment device as described above;

[0071] See also Fig.10 , Embodiment 3, a photographic kit of the present invention comprises a split-type pan-tilt head 37, wherein the split-type pan-tilt head 37 adopts the shift-type adjustment device as described above;

[0072] See also Fig.11 , Embodiment 4, a photography kit of the present invention comprises a quick-install live broadcasting platform 38, wherein the quick-install live broadcasting platform 38 adopts the shifting adjustment device as described above;

[0074] Among them, since this photography kit adopts all the technical solutions in the shift-type adjustment device as described above, it at least has all the technical effects brought by the above technical solutions, which will not be described one by one here.

[0075] 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.
