Description

Technical Field

[0001] The invention relates to the technical field of auxiliary photographic devices, and in particular to a gear head with a double clutch device. Background Art

[0002] The pan head is the most commonly used auxiliary equipment for photographers. The gear pan heads on the market have the functions of fine-tuning and quickly rotating the pan to adjust the shooting angle of the photographic equipment. The fine-tuning structure (mostly a worm and worm gear transmission structure) on the pan head drives the pan head center axis and the pan head base to slowly rotate relative to each other, thereby driving the clamp to swing in pitch to fine-tune the shooting angle of the photographic equipment.

[0003] When rotating the center axis of the gimbal to quickly adjust the shooting angle of the photographic equipment, you need to hold the photographic equipment with one hand and use the other hand to loosen the locking knob of the center axis of the gimbal, and then tighten the knob after the photographic equipment is rotated and adjusted to an appropriate position. If the photographic equipment is not held during this process, the gear gimbal may easily "nod" under the action of the gravity of the photographic equipment, which may easily cause the photographic equipment to break, posing a major safety hazard.

[0004] Therefore, how to make full use of the precise adjustment of the gear pan head and quickly and safely adjust the shooting angle of the photographic equipment when needed is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a gear head with a dual clutch device to solve the technical problem that in the prior art, the gear head with both fine-tuning and quick-adjusting functions is prone to "nod" under the action of the gravity of the photographic equipment when the lock of the central axis of the head is released for quick adjustment, which can easily cause the photographic equipment to be damaged.

[0006] The present invention is achieved through the following technical solutions:

[0012] A waist-shaped hole A matching with the driving shaft is penetrated in the middle of the clutch push block, and the opposite surfaces of the clutch push block and the locking member A protrude towards each other at intervals to form a plurality of sloped protrusions, and a matching groove matching with the shape of the protrusion is formed between two adjacent protrusions.

[0013] Furthermore, a limiting groove is provided on the hole wall of the through hole B along its length direction, and a limiting protrusion is integrally formed on the outer circumferential surface of the locking member A for cooperating with the limiting groove to limit the rotation of the locking member A.

[0014] Furthermore, a plurality of mounting holes are provided on a side of the clutch push block facing the locking member A, an elastic member B is installed in the mounting hole, and a positioning bead is fixedly provided on one end of the elastic member B facing the outlet of the mounting hole;

[0015] The end surface of the locking member A is provided with a plurality of positioning holes matched with the positioning beads, and the positioning beads partially extend into the positioning holes.

[0016] Furthermore, a positioning block is sleeved on the driving shaft, the positioning block is located between the two clutch push blocks, and a waist-shaped hole B matching the shape of the driving shaft is opened in the middle of the positioning block;

[0017] A limiting ring for limiting the rotation angle of the positioning block is fixedly connected in the through hole B.

[0018] Furthermore, a first bearing is installed between the clutch push block and the limiting ring, and an installation cavity for partially accommodating the first bearing is provided on the end surface of the clutch push block facing the limiting ring.

[0019] Furthermore, an adjustment hole is provided on the side of the pan / tilt base, and the adjustment hole is connected to the through hole A near the side of the fine-tuning mechanism; the fine-tuning mechanism includes a worm gear installed outside the driving shaft, and the worm gear is fixedly connected to the locking member B near the fine-tuning mechanism;

[0020] It also includes a worm meshing with the worm wheel, an outward end of the worm is integrally formed with an adjusting rod, and an end of the adjusting rod away from the worm is fixedly connected with a knob.

[0021] Furthermore, a stop ring is threadedly connected at the outlet of the adjustment hole, and the stop ring is sleeved outside the adjustment rod; and a flat head screw for fixing the knob and the adjustment rod is threadedly connected at the end of the adjustment rod.

[0022] Furthermore, a second bearing is installed on the locking member B near the worm gear side to assist its rotation;

[0023] A sealing plate is installed on the outward side of the worm gear, and the sealing plate is fixedly connected to the pan / tilt base. A switching handle is fixedly connected to the end of the drive shaft close to the sealing plate. End grooves are respectively provided on the opposite sides of the switching handle and the sealing plate, and a third bearing is commonly installed in the two end grooves.

[0024] Furthermore, the hole wall in the middle of the through hole A on the side away from the fine-tuning mechanism is deepened along its radial direction to form a blocking portion for installing the locking member B;

[0026] A fixing buckle threadedly connected to the locking member B is installed in front of the positioning buckle to connect the positioning buckle and the locking member B as a whole, and a fixing screw threadedly connected to the end of the driving shaft is installed in the fixing buckle.

[0027] The beneficial effects of the present invention are:

[0028] 1. The gear head of the present invention has a function of fine-tuning the shooting angle. When the two locking members on the side away from the fine-tuning mechanism are separated from each other under the action of the elastic member A, and the two locking members on the side close to the fine-tuning mechanism are engaged and locked with each other under the action of the clutch push block, in this state, the two mutually engaged and locked locking members can be driven to rotate through the fine-tuning mechanism, thereby driving the center axis of the head and the head base to slowly rotate relative to each other in pitch, thereby fine-tuning the shooting angle of the photographic equipment.

[0029] 2. The gear pan head of the present invention also has the function of quickly adjusting the shooting angle, that is, after the working states of the locking members on both sides are switched by the switching mechanism, the two locking members close to the side of the fine-tuning mechanism are separated from each other under the action of the elastic member A, and the two locking members away from the side of the fine-tuning mechanism are engaged and locked with each other under the action of the clutch push block. At this time, the fine-tuning mechanism does not work. In this state, the pan head center axis can be freely rotated, and in this state, the damping mechanism works to generate a damping force to prevent the locking members away from the side of the fine-tuning mechanism from rotating, so that when the pan head center axis is rotated to quickly drive the clamp seat to pitch and swing to adjust the shooting angle of the photographic equipment, the gear pan head can be prevented from "nodding" and damaging the photographic equipment under the action of gravity.

[0030] The gear pan head of the present invention can select a fine-tuning state or a quick-adjusting state through the dual-clutch device of the pan head. When the shooting angle of the photographic equipment needs to be quickly adjusted, the switching mechanism can be used to switch the gear pan head from the fine-tuning state to the quick-adjusting state. Under the action of the strong torque of the damping mechanism, the gear pan head can be prevented from "nodding" after the lock of the pan head central axis is released, causing the photographic equipment to be damaged. At the same time, since it has the damping mechanism, it also has a good damping hovering function. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] 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.

[0044] 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.

[0045] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The present invention provides a technical solution: a gear pan head with a dual clutch device, comprising a pan head base 1, the pan head base 1 is concave as a whole, and also comprises a pan head center axis 2 installed in the concave groove of the pan head base 1, the top of the pan head center axis 2 is installed with a clamping seat for installing photographic equipment, locking parts A4 are respectively installed at both ends of the pan head center axis 2, the pan head base 1 is respectively installed with locking parts B5 on both sides of the pan head base 1 facing the pan head center axis 2, the locking parts A4 and the locking parts B5 can adopt a right-angle structure or other shapes of toothed disc structures that can bite each other, and a fine-tuning mechanism 3 is provided on the right side of the pan head base 1;

[0046] In the fine-tuning state, the two locking pieces on the side away from the fine-tuning mechanism 3 are separated from each other, and the two locking pieces on the side close to the fine-tuning mechanism 3 are engaged and locked with each other, and in this state, the mutually locked locking pieces are driven to rotate by the fine-tuning mechanism 3, thereby driving the pan head center axis 2 to rotate, and when the pan head center axis 2 rotates, it can drive the clamp seat to pitch and swing, so as to fine-tune the shooting angle of the photographic equipment;

[0047] An elastic member A6 is installed between the locking member A4 and the locking member B5. In the present application document, the elastic members are all springs, and other elastic structures in the prior art that can achieve the same purpose, such as elastic rubber rings, etc., can also be used. The pan / tilt center axis 2 is provided with a switching mechanism 7 for cooperating with the elastic member A6 to drive the locking member A4 to move, thereby switching the working states of the locking members on both sides. The switching mechanism 7 can push the locking member A4 to move and cooperate with the locking member B5 for locking, and at the same time release the blocking of the other locking member A4. At this time, the locking member A4 is separated from the locking member B5 under the action of the elastic member A6 to achieve the purpose of switching the working state;

[0048] A damping mechanism 8 connected to the locking member B5 is provided on the side of the gimbal base 1 away from the fine-tuning mechanism 3. When the two locking members on one side of the fine-tuning mechanism 3 are separated from each other under the action of the switching mechanism 7, and the two locking members on one side of the damping mechanism 8 are engaged and locked with each other, the gimbal center axis 2 and the gimbal base 1 can be driven to rotate, so that the clamp seat can be freely and quickly driven to pitch and swing to adjust the shooting angle of the photographic equipment, and at this time, the damping mechanism 8 works, and the strong torque of the damping mechanism 8 prevents the gear gimbal from "nodding" under the action of gravity, thereby preventing the photographic equipment from being damaged during rapid adjustment.

[0049] Regarding the switching mechanism 7:

[0050] See also Figure 3 , Figure 4 , Figure 5 and Figure 7 The two opposite side walls of the pan / tilt base 1 and the end of the pan / tilt center axis 2 are respectively provided with through holes A11 and through holes B21. The switching mechanism 7 includes a driving shaft 71, which crosses the two through holes and passes through a plurality of locking members in sequence. The end face of the driving shaft 71 is in a flat key shape, and two clutch push blocks 72 are mounted on the driving shaft 71. The two clutch push blocks 72 are respectively located on the inner side of the two locking members A4. A waist-shaped hole A73 matching the driving shaft 71 is provided in the middle of the clutch push block 72. When the driving shaft 71 rotates, the clutch push block 72 can be driven to rotate synchronously.

[0051] See also Figure 7 and Figure 8 The clutch push block 72 and the locking member A4 have opposing surfaces that are spaced apart and project toward each other to form a plurality of ramp-shaped projections 74, and a matching groove 75 that matches the shape of the projection 74 is formed between two adjacent projections 74. When the clutch push block 72 rotates under the action of the drive shaft 71, causing the projection 74 and the matching groove 75 to tend to overlap, the distance between the clutch push block 72 and the locking member A4 gradually decreases, and under the action of the elastic member A6, the locking member A4 is pushed close to the clutch push block 72, and at this time, the locking member A4 and the locking member B5 move away from each other to release the locking state;

[0052] When the clutch push block 72 rotates under the action of the driving shaft 71, causing the relative protrusions 74 to move along the opposite inclined surfaces, the clutch push block 72 pushes the locking member A4 to move and squeezes the elastic member A6, so that the locking member A4 engages with the locking member B5 for locking.

[0053] See also Figure 4 , Figure 5 and Figure 7 The clutch push block 72 is provided with a plurality of mounting holes 12 on one side facing the locking member A4, an elastic member B13 is installed in the mounting hole 12, and a positioning bead 14 is fixedly provided on one end of the elastic member B13 facing the outlet of the mounting hole 12;

[0054] The end surface of the locking member A4 is provided with a plurality of positioning holes 15 that cooperate with the positioning beads 14, and the positioning beads 14 partially extend into the positioning holes 15. When the clutch push block 72 rotates under the action of the drive shaft 71, the locking member A4 squeezes the positioning beads 14. When the clutch push block 72 rotates so that the positioning beads 14 are aligned with the positioning holes 15 on the locking member A4, the positioning beads 14 are pushed into the positioning holes 15 under the action of the elastic member B13, thereby having a mechanical feel in the process of rotating the drive shaft 71 to drive the clutch push block 72, thereby improving the user experience.

[0055] See also Figures 3 to 5 A limiting groove 9 is provided on the hole wall of the through hole B21 along its length direction, and a limiting protrusion 10 is integrally formed on the outer circumferential surface of the locking member A4 for cooperating with the limiting groove 9 to limit the rotation of the locking member A4. Through the sliding cooperation between the limiting protrusion 10 and the limiting groove 9, the locking member A4 can only move axially relative to the pan / tilt center axis 2 but cannot rotate circumferentially, thereby ensuring that the clutch push block 72 or the elastic member A6 can smoothly push the locking member A4 to move and engage with the locking member B5 for locking or separation.

[0056] See also Figure 3 and Figure 6 The drive shaft 71 is sheathed with a positioning block 16, which is located between the two clutch push blocks 72. The positioning block 16 is in the shape of a three-quarter round handle, and a waist-shaped hole B17 matching the shape of the drive shaft 71 is opened in the middle of the positioning block 16, so that the positioning block 16 can be driven to rotate synchronously when the drive shaft 71 rotates;

[0057] A limit ring 18 for limiting the rotation angle of the positioning block 16 is fixedly connected in the through hole B21. The limit ring 18 has a quarter boss. When the positioning block 16 rotates in the limit ring 18 until its end face contacts the boss in the limit ring 18, the rotation of the positioning block 16 can be limited, thereby limiting the rotation angle of the drive shaft 71, so as to clearly know whether the working state of the switching mechanism 7 is switched to the right position.

[0058] See also Figure 3 and Figure 4 A first bearing 19 is installed between the clutch push block 72 and the limit ring 18, and a mounting cavity 20 for partially accommodating the first bearing 19 is opened on the end surface of the clutch push block 72 facing the limit ring 18. The first bearing 19 adopts a plane thrust bearing. The first bearing 19 can reduce the friction caused by the axial load when the clutch push block 72 rotates, which helps to improve the efficiency and user experience of the system.

[0059] Regarding the fine-tuning mechanism 3:

[0060] See also Figure 2 , Figure 3 and Figure 5 The side of the pan / tilt base 1 is provided with an adjustment hole 31, and the adjustment hole 31 is connected to the through hole A11 near the side of the fine-tuning mechanism 3; the fine-tuning mechanism 3 includes a worm gear 32 installed outside the driving shaft 71, and the worm gear 32 is fixedly connected to the locking member B5 near the fine-tuning mechanism 3;

[0061] It also includes a worm 33 meshing with the worm wheel 32, and an adjusting rod 34 is integrally formed at the outward end of the worm 33, and a knob 35 is fixedly connected to the end of the adjusting rod 34 away from the worm 33. The worm 33 can be driven to rotate by rotating the knob 35 and the adjusting rod 34, thereby driving the worm wheel 32 to rotate. Since the worm wheel 32 is fixedly connected to the locking member B5, when the two locking members close to the side of the fine-tuning mechanism 3 are engaged and locked, the worm wheel 32 can drive the pan head center axis 2 and the pan head base 1 to rotate relative to each other through the cooperation of the two locking members, and then the shooting angle of the photographic equipment can be fine-tuned by rotating the knob 35.

[0062] See also Figure 2 The outlet of the adjusting hole 31 is threadedly connected with a stop ring 36, and the stop ring 36 is sleeved outside the adjusting rod 34. The stop ring 36 is used to prevent the worm 33 from moving axially, so that the worm 33 is stably installed in the adjusting hole 31; the end of the adjusting rod 34 is threadedly connected with a flat head screw 37 for fixing the knob 35 and the adjusting rod 34, so that the knob 35 and the adjusting rod 34 are connected as a whole. When the knob 35 is rotated, the adjusting rod 34 can be driven to rotate synchronously, thereby driving the worm 33 to rotate;

[0063] Plane thrust bearings are installed at both ends of the worm 33 and between the knob 35 and the stop ring 36. The plane thrust bearings can reduce the friction caused by the axial load, which helps to improve the efficiency of the system and the user experience.

[0064] See also Figure 3 and Figure 5 A second bearing 22 for assisting its rotation is installed on the locking piece B5 close to the side of the worm gear 32, and the second bearing 22 adopts a ball bearing. A sealing plate 23 is installed on the outward side of the worm gear 32, and the sealing plate 23 is fixed in the through hole A11 on the right side of the pan / tilt base 1 by a threaded connection, so as to limit the axial movement of the worm gear 32 and other components. A switching handle 25 is fixedly connected to one end of the driving shaft 71 close to the sealing plate 23, and the switching handle 25 is used to facilitate the rotation of the driving shaft 71. End grooves 24 are respectively provided on the opposite sides of the switching handle 25 and the sealing plate 23, and a third bearing 26 is installed in the two end grooves 24. The third bearing 26 adopts a plane thrust bearing, and the third bearing 26 is used to reduce the friction caused by the axial load when the driving shaft 71 is rotated by the switching handle 25, which helps to improve the efficiency and user experience of the system.

[0065] Regarding the damping mechanism 8:

[0066] See also Figure 3 and Figure 4 The hole wall of the middle part of the through hole A11 away from the side of the fine-tuning mechanism 3 is deepened along its radial direction to form a blocking portion 81 for mounting the locking member B5. The damping mechanism 8 includes two damping washers 82 respectively mounted on both sides of the blocking portion 81. A positioning buckle 83 plugged with the locking member B5 is mounted in front of the damping washers 82 on the outward side, so that the locking member B5 can drive the positioning buckle 83 to rotate synchronously when the locking member B5 rotates;

[0067] A fixing buckle 84 threadedly connected to the locking piece B5 is installed in front of the positioning buckle 83 to connect the positioning buckle 83 and the locking piece B5 as a whole. A fixing screw 85 threadedly connected to the end of the driving shaft 71 is installed in the fixing buckle 84. When the two locking pieces on the side away from the fine-tuning mechanism 3 are engaged and locked with each other, the fixing buckle 84 and the positioning buckle 83 can be driven to rotate synchronously through the locking piece by rotating the gimbal center axis 2. The damping force is generated by contacting the blocking part 81 when the damping gasket 82 moves. Therefore, when the gimbal center axis 2 is rotated to quickly drive the clamp seat to pitch and swing to adjust the shooting angle of the photographic equipment, the gear gimbal is prevented from "nodding" and damaging the photographic equipment under the action of gravity, and the damping force can be adjusted by adjusting the locking degree of the fixing buckle 84 and the locking piece B5.

[0068] The working principle of the present invention is as follows: in the fine-tuning state, the two locking members far from the fine-tuning mechanism 3 are separated from each other under the action of the elastic member A6, and the two locking members close to the fine-tuning mechanism 3 are engaged and locked with each other under the action of the clutch push block 72. In this state, by rotating the knob 35, the knob 35 and the adjusting rod 34 cooperate to drive the worm 33 to rotate, and then drive the worm wheel 32 to rotate. Since the worm wheel 32 is fixedly connected to the locking member B5, when the two locking members close to the fine-tuning mechanism 3 are engaged and locked, the worm wheel 32 can drive the pan head center axis 2 and the pan head base 1 to rotate relative to each other through the cooperation of the two locking members, and then the shooting angle of the photographic equipment can be fine-tuned by rotating the knob 35.

[0069] When it is necessary to quickly adjust the shooting angle of the photographic equipment, according to the direction indicated by the rotation mark on the side of the pan / tilt base 1, the drive shaft 71 is rotated by the switching handle 25 until the drive shaft 71 cannot rotate under the cooperation of the positioning block 16 and the limit ring 18. When the drive shaft 71 rotates, the two clutch push blocks 72 are respectively driven to rotate synchronously. The clutch push block 72 close to the side of the fine adjustment mechanism 3 rotates so that the matching groove 75 of the protrusion 74 tends to overlap. At this time, the locking member A4 is pushed away from the locking member B5 under the action of the elastic member A6, thereby releasing the locking state of one side of the fine adjustment mechanism 3;

[0070] The clutch push block 72 away from the side of the fine-tuning mechanism 3 rotates to cause the protrusion 74 to separate from the matching groove 75. At this time, the protrusion 74 moves along the inclined surface of the other relative protrusion 74 to push the locking piece A4 close to the locking piece B5 for engagement and locking, thereby completing the state switching of the locking pieces on both sides. At this time, the fine-tuning mechanism 3 does not work. In this state, the gimbal center axis 2 and the gimbal base 1 can rotate freely relative to each other, and when the gimbal center axis 2 rotates, the gimbal center axis 2 drives the fixing buckle 84 and the positioning buckle 83 to rotate synchronously through the locking piece, and then drives the damping gasket 82 to rotate synchronously. When the damping gasket 82 moves, it contacts the blocking part 81 to generate a damping force, so that when the gimbal center axis 2 is rotated to quickly drive the clamp seat to pitch and swing to adjust the shooting angle of the photographic equipment, the gear gimbal can be prevented from "nodding" and damaging the photographic equipment under the action of gravity.

[0071] 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.
