Description

Technical Field

[0001] The invention relates to a rotating central axis quick disassembly and assembly system for a photographic apparatus. Background Art

[0002] According to market research and patent searches, existing photography and video equipment are placed on tripods and pan heads for fixation, and the center axis (threaded axis) needs to be locked to keep the camera fixed for use; and the locking operation is carried out by screwing, and the previous screwing structure is relatively complicated, starting from the bottom of the center axis, and requires many rotation operations, especially when used in natural landscapes or other situations where real-time and rapid locking and capturing are required. It is not possible to quickly disassemble and assemble, and the best operation cannot be achieved, and the movement stability and safety are poor. The locking operation is generally carried out by a spiral structure, which is inconvenient to operate and is prone to aging, slipping, or loosening after long-term use. Therefore, we have developed a rotating center axis quick disassembly system for photographic equipment. Summary of the Invention

The following further describes the specific embodiments of the present invention with reference to the drawings of the specification, so that the technical solutions and their beneficial effects of the present invention are clearer and more definite.

[0032] Specifically refer to Figure 1-7 to describe specific embodiments. However, those skilled in the art will easily understand that the detailed description given herein with respect to these drawings is for illustrative purposes only and should not be construed as restrictive; this embodiment provides a quick disassembly and assembly system for the central axis of a photographic apparatus, which includes a touch top device 1, a rotary control device 2, and a clutch drive device 3. The clutch drive device 3 is installed between the touch top device 1 and the rotary control device 2. The clutch drive device 3 includes a seat body 31, a locking movable block 32, a first screw connection block 33, a second screw connection block 34, and a clutch control member 35; by means of the clutch control member 35, the first screw connection block 33 and the second screw connection block 34 are made to approach each other to cooperate with the insertion bolt 4 and be in a biting state, or the first screw connection block 33 and the second screw connection block 34 are made to move relatively away from each other to disengage from the insertion bolt 4 and be in an unlocked state.

[0033] The seat body 31 provides a placement cavity 311 for the first screw connection block 33 and the second screw connection block 34 to be embedded and capable of relative movement. The placement cavity 311 communicates with the locking cavity 312. When the locking movable block 32 enters the locking cavity 312, it holds the first screw connection block 33 and the second screw connection block 34 to prevent them from disengaging; when the clutch control member 35 drives the locking movable block 32 to leave the locking cavity 312, the first screw connection block 33 and the second screw connection block 34 are not restricted by the locking movable block 32 and move relatively away from each other to unlock, so as to achieve quick disassembly and assembly.

[0034] In this embodiment, the rotary control device 2 provides a guiding cavity 21 for the locking movable block 32. There may be two locking movable blocks 32, which may be symmetrically arranged. The locking movable block 32 is within the guiding cavity 21 and is elastically abutted against the rotary control device 2 by means of a spring 5, so that the locking movable block 32 moves upward into the locking cavity 312. At this time, the first screwing block 33 and the second screwing block 34 are relatively close to each other and can be connected to the plug bolt 4 for engaging operation to lock.

[0035] The seat body 31 provides a movable cavity 313 for the clutch control member 35. The number of the clutch control members 313 is two, and they are relatively and symmetrically arranged to connect the corresponding first screwing block 33 and second screwing block 34 to form a two-way drive clutch, and can be operated by pressing with one hand during use.

[0036] A return spring 6 is provided between the clutch control member 35 and the seat body 31. Guide posts 7 are connected between the clutch control member 35 and the first screwing block 33 and the second screwing block 34. The number of the guide posts 7 is multiple, and they are arranged at intervals and parallel to each other in axis. The seat body 31 provides guide holes 314 for the guide posts 7. The guide posts 7 move within the guide holes 314 and are elastically abutted by the elastic force of the return spring 6. When the clutch control member 35 presses the locking movable block 32 to disengage from the locking cavity 312 and enter the guiding cavity 21, the first screwing block 33 and the second screwing block 34 move relatively away from each other under the action of the return spring 6 to form unlocking, so that the plug bolt 4 can be quickly disengaged.

[0037] The placing cavity 311 provides two-side guiding portions 315 for the hanging member 36. A holding spring 8 is provided between the hanging member 36 and the rotary control device 2. The hanging member 36 is provided with a bottom support 361, and the bottom support 361 elastically abuts against the first screwing block 33 and the second screwing block 34 to prevent the first screwing block 33 and the second screwing block 34 from shifting up and down when moving.

[0038] The contact top device 1 includes an open shell 11, a turntable 12 and a turntable seat 13. The turntable seat 13 is provided with an insertion hole 131 for the plug bolt 4 to be inserted. The turntable seat 13 provides a connection through hole 132 for the rotary drive column 9. The rotary drive column 9 passes through the turntable seat 13 and the seat body 31 and is connected to the rotary control device 2, so that when the rotary control device 2 rotates, it drives the turntable seat 13 and the seat body 31 to rotate.

[0039] The first screwing block 33 and the second screwing block 34 are respectively provided with semi-circular internal screw threads 331 and 341. The clutch control member 35 is provided with an inclined guiding surface 351, and the locking movable block 32 provides a pressing inclined surface 321 to cooperate with the inclined guiding surface 351. The rotary control device 2 is in a cylindrical shape, and the rotary control device 2 is provided with a lower through hole 22, and the lower through hole 22 is coaxially arranged with the connection through hole 131.

[0040] Combining the above embodiments and together with all the drawings, the camera and the photographic apparatus 10 are placed on the camera support tripod, and the insertion bolt 4 is installed to extend downward. When it needs to be tightened, the insertion bolt 4 is sleeved at a position close to the platform of the tripod. By operating the clutch control member 35, the first screwing block 33 and the second screwing block 34 are engaged with the insertion bolt 4. The rotation control device 2 is placed so that the first screwing block 33 and the second screwing block 34 are screwed relative to the insertion bolt 4 to make the contact top device 1 push upward and lock. When it needs to be loosened, the clutch control member 35 is pressed and pushed inward so that the locking movable block 32 moves downward into the guide cavity 21 and disengages from the locking cavity 312, so that the first screwing block 33 and the second screwing block 34 bounce off each other under the action of the return spring 6, thereby disengaging the insertion bolt 4 from the first screwing block 33 and the second screwing block 34 to form an unlocked state; in this way, the present invention can quickly realize disassembly and assembly operations, with strong versatility, simple structure, stable and reliable, etc. Therefore, it has superior performance in terms of technology, economy and practicality.
