Abstract
Description
Technical Field
[0001] This utility model relates to the field of photographic gimbal technology, specifically providing a self-locking photographic gimbal. Background Technology
[0002] Most photography tripods are currently hydraulically damped tripods, which have two damping intensity adjustment knobs in the horizontal rotation direction and the pitch rotation direction. One is for multi-level damping intensity adjustment, which is used to achieve smooth and stable horizontal rotation; the other is for locking knobs, which are similar to set screws. After adjusting the horizontal rotation angle and pitch rotation angle, tightening the locking knob will stop the tripod from rotating horizontally or in pitch.
[0003] The main drawback of this design is that if the photographer forgets to tighten the suspension locking knob after leaving the gimbal during shooting, the camera body and lens are heavy and unbalanced, making it easy to tip over and damage the camera.
[0004] Even if the photographer tightens the locking knob before leaving the gimbal, it is still fixed by friction. When the camera lens is long or heavy, there is a risk of tipping over or the pitch angle gradually changes, which is not conducive to stable shooting. Utility Model Content
[0005] This invention provides a self-locking camera gimbal, which solves the problem that existing camera gimbals do not have a self-locking function.
[0006] This utility model provides a self-locking photographic gimbal, comprising:
[0007] Base;
[0008] The pitch-fixed base includes a base frame and at least two side frames, the side frames being fixedly connected to the base frame, and the base frame being rotatably connected to the base to form a first rotation;
[0009] The pitch moving seat is rotatably connected to the pitch fixed seat via a rotating shaft to form a second rotation, and is located between the side frames. The rotating shaft is fixedly connected to the pitch moving seat.
[0010] A compression elastic element is disposed on the rotating shaft to provide axial elastic force;
[0011] A clutch disc is connected to the compression elastic element and is slidably disposed on the rotating shaft on the same axis. A first mating element is disposed on the clutch disc.
[0012] A limiting mechanism is provided at the connection between the clutch disc and the rotating shaft to constrain the rotation of the clutch disc relative to the rotating shaft.
[0013] The second mating component is disposed on the side frame and can be connected to the first mating component to constrain the rotation of the rotating shaft;
[0014] The pressing assembly, connected to the clutch disc, is used to press the clutch disc away from the side frame;
[0015] Wherein, the first rotation and the second rotation are perpendicular to each other.
[0016] According to the self-locking camera gimbal provided by this utility model, a receiving cavity is provided at one end of the rotating shaft near the clutch disc, and the compression elastic element and the pressing component are disposed in the receiving cavity;
[0017] The limiting mechanism includes a limiting pin, and the cavity wall of the accommodating cavity is provided with a plurality of clearance elongated holes along the axial direction. The two ends of the limiting pin pass through the pressing component and the clearance elongated holes and extend into the clutch disc.
[0018] According to the self-locking camera gimbal provided by this utility model, a locking groove is provided at one end of the cavity wall of the accommodating cavity near the pressing component;
[0019] The pressing component is provided with a locking pin, and the locking groove can cooperate with the locking pin to restrain the rebound of the pressing component.
[0020] According to the self-locking camera head provided by this utility model, the first mating part and the second mating part are toothed rings that can mesh with each other.
[0021] According to the self-locking camera gimbal provided by this utility model, the compression elastic element is a compression spring.

[0025] The self-locking camera gimbal provided by this utility model also includes a torque member, which is coaxially sleeved on the rotating shaft and disposed between the clutch disc and the pitch moving base. The two ends of the torque member are respectively connected to the clutch disc and the pitch moving base.
[0026] According to the self-locking camera gimbal provided by this utility model, the torque component is a torsion spring.
[0027] This utility model provides a self-locking camera head that effectively solves the problem of existing camera heads lacking a self-locking function by incorporating a clutch-type self-locking mechanism between the traditional tilt station and tilt arm. This effectively prevents the camera from easily tipping over when the photographer leaves the head support and forgets to tighten the suspension locking knob. Specifically:
[0028] By using a compression elastic element, an axial thrust can be provided to the clutch disc, ensuring that the clutch disc always tends to move towards the pitch fixed seat side frame. The clutch disc and the first mating element on it can connect with the second mating element on the side frame, thereby preventing the clutch disc from rotating and further preventing the pitch moving seat from rotating. The limiting mechanism restricts the rotation of the clutch disc relative to the shaft, ensuring that even when the clutch disc is in a movable sleeve position, it maintains synchronous rotation and stillness with the shaft. The pressing component allows for pressing the clutch disc and compressing the compression elastic element.

[0046] The following is combined Figures 1 to 8 The embodiments shown illustrate the technical solution of this utility model:
[0047] This utility model embodiment provides a self-locking photographic gimbal, such as Figure 1 and Figure 2 As shown, it includes: a base 1, a pitch fixed seat 2, a pitch movable seat 3, a compression elastic element 4, a clutch disc 5, a limiting mechanism 6, a second mating part 9, and a pressing assembly 8;
[0048] The pitch station 2 includes a base frame 201 and at least two side frames 202. The side frames 202 are fixed to the base frame 201, and the base frame 201 is rotatably connected to the base 1 to form a first rotation. The pitch moving seat 3 is rotatably connected to the pitch station 2 via a rotating shaft 10 to form a second rotation and is located between the side frames 202. The rotating shaft 10 is fixed to the pitch moving seat 3. A compression elastic element 4 is disposed on the rotating shaft 10 to provide axial elastic force. The clutch disc 5 is connected to the compression elastic element 4 and is slidably disposed on the rotating shaft 10. A first mating element 7 is disposed on the clutch disc 5. A limiting mechanism 6 is disposed at the connection between the clutch disc 5 and the rotating shaft 10 to constrain the rotation of the clutch disc 5 relative to the rotating shaft 10. A second mating element 9 is disposed on the side frame 202 and can be connected to the first mating element 7 to constrain the rotation of the rotating shaft 10. A pressing component 8 is connected to the clutch disc 5 to press the clutch disc 5 away from the side frame 202. The first rotation and the second rotation are perpendicular to each other.
[0049] It is understandable that the compression elastic element 4 can be a compression spring, elastic rubber or elastic telescopic rod, etc., as long as it can achieve axial elastic force; of course, the compression elastic element 4 can be set in the inner cavity of the rotating shaft 10, or it can be coaxially sleeved on the outer wall of the rotating shaft 10. Ultimately, it needs to be connected to the clutch disc 5 to provide elastic force for the movement of the clutch disc 5.
[0050] The limiting mechanism 6 can be the cooperation between the limiting pin 601 and the limiting groove, or it can be other limiting structures that enable the clutch disc 5 to slide in the axial direction of the rotating shaft 10, while preventing it from rotating on the rotating shaft 10.
[0051] In this embodiment, as Figure 1 and Figure 2 As shown, the base 1 is a damped rotating base 1, providing rotation on the horizontal plane for the entire gimbal. The pitch fixed base 2 includes a base frame 201 and two side frames 202, forming a U-shaped base. The pitch movable base 3 is generally cylindrical and is rotatably connected between the two side frames 202 of the pitch fixed base 2 via a rotating shaft 10. The compression elastic element 4 is preferably a compression spring, which is installed in the inner cavity of the rotating shaft 10 and abuts against the cavity wall and one end of the pressing assembly 8. The clutch disc 5 is slidably installed on the rotating shaft 10. The limiting mechanism 6 includes a limiting pin 601 and an clearance elongated hole 602 opened on the inner cavity wall of the rotating shaft 10 (see...). Figure 3 The limiting pin 601 passes through the pressing assembly 8 and extends into the clutch disc 5, thus enabling axial sliding of the clutch disc 5 and circumferential locking, constraining the rotation of the clutch disc 5 relative to the rotating shaft 10; a first mating part 7 is provided on the end face of the clutch disc 5 away from the compression elastic member 4, the first mating part 7 can be a male toothed ring or male head, etc., and correspondingly, a female toothed ring or female head is provided on the side frame 202, so that the two can cooperate with each other to achieve anti-rotation.
[0052] This utility model provides a self-locking camera head. By incorporating a clutch-type self-locking mechanism between the traditional tilt station 2 and tilt moving station 3, it effectively solves the problem of existing camera heads lacking a self-locking function. This effectively prevents the camera from easily tipping over when the photographer leaves the head support and forgets to tighten the suspension locking knob. Specifically:
[0053] By providing the compression elastic element 4, an axial thrust can be provided to the clutch disc 5, so that the clutch disc 5 always tends to move towards the side frame 202 of the pitch fixed seat 2; by providing the clutch disc 5 and the first mating element 7 provided on the clutch disc 5, it can be connected with the second mating element 9 provided on the side frame 202, thereby achieving anti-rotation of the clutch disc 5 and further achieving anti-rotation of the pitch moving seat 3; by providing the limiting mechanism 6, the rotation of the clutch disc 5 relative to the rotating shaft 10 can be constrained, thereby achieving synchronous rotation and stillness with the rotating shaft 10 even when the clutch disc 5 is in the movable sleeve state; by providing the pressing component 8, the clutch disc 5 can be pressed and the compression elastic element 4 can be compressed.
[0054] According to the self-locking camera gimbal provided by this utility model, such as Figure 3 and Figure 4 As shown, a receiving cavity 1001 is provided at one end of the rotating shaft 10 near the clutch disc 5, and the compression elastic element 4 and the pressing assembly 8 are disposed in the receiving cavity 1001;
[0055] The limiting mechanism 6 includes a limiting pin 601, and a plurality of clearance holes 602 are provided on the cavity wall of the accommodating cavity 1001 along the axial direction. The two ends of the limiting pin 601 pass through the pressing assembly 8 and the clearance holes 602, and extend into the clutch disc 5.
[0056] In this embodiment, the rotating shaft 10 has two clearance holes 602 on its inner wall near the pressing component 8, which are located at the upper and lower positions of the rotating shaft 10 respectively. The limiting pin 601 passes through the pressing component 8 and the clearance holes 602, and extends to both ends into the clutch disc 5 and is fixedly connected to the clutch disc 5.
[0057] In this way, the clutch disc 5 can be axially slidable and locked in the circumferential direction, thus constraining the rotation of the clutch disc 5 relative to the rotating shaft 10.
[0058] According to the self-locking camera gimbal provided by this utility model, such as Figure 4 and Figure 5 As shown, a slot 1102 is provided on the cavity wall of the accommodating cavity 1001 near the end of the pressing component 8;
[0059] The pressing component 8 is provided with a locking mechanism 11, which includes a locking pin 1101 and a locking groove 1102. The locking groove 1102 can cooperate with the locking pin 1101 to restrain the pressing component 8 from rebounding.
[0060] In this embodiment, the locking pin 1101 and the button 802 of the pressing component 8 are integrally formed. The locking groove 1102 is opened at the end of the cavity wall of the receiving cavity 1001 near the pressing component 8. When the pressing component 8 is pushed, the clutch disc 5 will be in the unlocked state, that is, away from the side frame 202. At this time, rotating the button 802 can screw the locking pin 1101 into the locking groove 1102. In this way, the clutch disc 5 can always be in the unlocked state, so that the photographer can adjust the tilt seat 3 at will without having to press the button 802 all the time. After the angle adjustment is completed, rotating the button 802 in the opposite direction can restore the self-locking function of the clutch disc 5.
[0061] According to the self-locking camera gimbal provided by this utility model, such as Figure 6 and Figure 7 As shown, the first mating part 7 and the second mating part 9 are toothed rings that can mesh with each other.
[0062] In this embodiment, the first mating part 7 and the second mating part 9 are preferably toothed rings with the same module and number of teeth. The toothed rings are coaxially fixedly installed on the clutch disc 5 and the side frame 202 respectively to achieve self-locking of the clutch disc 5. Preferably, the toothed rings have the characteristics of high stability, uniform force on each part, and large self-locking bearing capacity.
[0063] According to the self-locking camera gimbal provided by this utility model, such as Figure 2 and Figure 4 As shown, the pressing assembly 8 includes a push rod 801 and a button 802. The push rod 801 is slidably disposed in the receiving cavity 1001, and one end abuts against the compression elastic member 4. The limiting pin 601 passes through the push rod 801. The button 802 is fixedly connected to the end of the push rod 801 away from the compression elastic member 4.
[0064] Therefore, the button 802 can be pressed from outside the rotating shaft 10, thereby pushing the compression spring.
[0065] According to the self-locking camera gimbal provided by this utility model, such as Figure 8 As shown, it also includes a torque member 12, which is coaxially sleeved on the rotating shaft 10 and disposed between the clutch disc 5 and the pitch moving seat 3. The two ends of the torque member 12 are respectively connected to the clutch disc 5 and the pitch moving seat 3.
[0066] In this embodiment, the torque element 12 is preferably a torsion spring, which is coaxially sleeved on the rotating shaft 10, and its two ends are respectively connected to the clutch disc 5 and the pitch moving seat 3. This can achieve a certain rotational buffer for the pitch moving seat 3 in the case of sudden locking of the clutch disc 5, so that the pitch moving seat 3 will not also suddenly lock, thereby causing deformation of the rotating shaft 10 or breakage of the clutch disc 5.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
