Abstract
Description
Technical Field
[0001] This utility model relates to the field of film and television equipment, and in particular to an adjustment mechanism and film and television equipment. Background Technology
[0002] In film and television production, equipment such as cameras, lights, and softboxes all require stands for fixation and support. However, due to significant differences in equipment specifications, their weights and center of gravity distributions vary. Traditional stand designs are relatively fixed and struggle to flexibly adapt to the weight distribution requirements of various equipment. This leads to issues such as center of gravity shift and instability when supporting different devices, which not only affects the normal operation of the equipment but may also cause equipment damage or personal injury due to equipment tipping over.
[0003] While attempting to adjust the center of gravity by disassembling and reassembling the support structure to meet the support needs of different equipment can theoretically solve the stability problem, it faces numerous difficulties in practice. Repeated disassembly and reassembly of the support is not only time-consuming and labor-intensive, requiring specialized tools and technicians, but can also lead to wear and tear on support components due to frequent disassembly, reducing its lifespan. Utility Model Content
[0004] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide an adjustment mechanism that, through the relative displacement of the adjustment seat and the connecting seat, enables flexible adjustment of the center of gravity of the equipment, effectively reducing the risk of swaying, tilting and tipping caused by the shift of the center of gravity.
[0005] The second objective of this invention is to provide a film and television device that allows for real-time adjustment of the position of the connecting bracket via a movable adjustment seat, thereby adjusting the device's center of gravity relative to the bracket, making operation convenient and efficient, and reducing the risk of tipping over.
[0006] One of the objectives of this utility model is achieved through the following technical solution:
[0007] An adjustment mechanism, comprising:
[0008] Connecting seat, wherein the connecting seat is provided with a plurality of first limiting parts;
[0009] An adjusting seat is slidably disposed on the connecting seat, and the adjusting seat is movable on the connecting seat along a first direction;
[0010] A first locking member is disposed on the adjusting seat and movably connected to the adjusting seat, and a second limiting part is provided on the first locking member;
[0011] When the second limiting part engages with one of the first limiting parts, the adjusting seat is locked relative to the connecting seat; when the second limiting part separates from the first limiting part, the adjusting seat is unlocked relative to the connecting seat.
[0012] Furthermore, the adjusting seat is provided with a sliding groove and a first through groove. The sliding groove extends along the first direction, and the first through groove extends along the second direction and passes through the sliding groove. The connecting seat is slidably installed in the sliding groove, and the first locking member is rotatably installed in the first through groove.
[0013] The first limiting part includes a limiting groove, and the second limiting part includes a limiting protrusion. The limiting protrusion is provided with a guide surface, which slides in cooperation with the groove wall of the limiting groove to guide the limiting protrusion to slide into or out of the limiting groove.
[0014] Furthermore, it also includes a second locking member, which is mounted on the adjusting seat;
[0015] In the locked state, the first locking member engages with the second locking member;
[0016] In the unlocked state, the first locking member is separated from the second locking member.
[0017] Furthermore, the first locking member includes a first end and a second end, the first end being rotatably connected to the adjusting seat, and the second limiting part being disposed at the first end;
[0018] The second locking member is provided with a first stop, and the second end is provided with a second stop;
[0019] In the locked state, the first stop and the second stop are engaged;
[0020] In the unlocked state, the first stop part and the second stop part are separated.
[0021] Furthermore, the second locking member is movably connected to the adjusting seat via the first elastic member, which provides an elastic force to drive the first stop portion to move closer to the second stop portion.
[0022] Furthermore, the top of the second locking member is also provided with a limiting buckle, which extends out of the edge of the adjusting seat.
[0023] Furthermore, the adjusting seat is also provided with a second elastic element, which provides an elastic force to drive the second end to rotate away from the adjusting seat.
[0024] Furthermore, the second end is also provided with a gripping part, which extends out of the edge of the adjusting seat; the gripping part is also provided with a gripping groove.
[0025] Furthermore, the top and bottom of the connecting seat are each provided with a plurality of the first limiting portions;
[0026] The adjustment mechanism also includes a third locking member and a third elastic member. The adjustment seat is provided with a second through groove that is opposite to the first through groove. The second through groove passes through the adjustment seat and is connected to the connecting seat. The third locking member is installed in the second through groove through the third elastic member. The third elastic member provides an elastic force to drive the third locking member to cooperate with the first limiting part located at the bottom of the connecting seat.
[0027] The technical solution adopted for the second objective of this utility model is:
[0028] A film and television device includes a main body, a connecting bracket, and an adjustment mechanism, wherein the connecting base is connected to the main body and the adjustment base is connected to the connecting bracket.
[0029] In summary, the adjustment mechanism and audio-visual equipment provided by this utility model have the following technical effects:
[0030] In practical use, the connecting seat is securely connected to the main body of the equipment, and the adjusting seat is connected to the connecting bracket. Since the adjusting seat can achieve relative displacement with the connecting seat in the first direction (i.e., the length direction of the connecting seat), the position of the connecting bracket relative to the main body of the equipment can be dynamically adjusted in real time.
[0031] When it is necessary to adjust the center of gravity distribution of the main body of the equipment, the operator only needs to slide the adjusting seat along the first direction to change the relative position of the main body of the equipment and the connecting bracket, thereby achieving a redistribution of the center of gravity. After adjusting to the ideal position, the first locking part is operated to engage the second limiting part with the first limiting part on the connecting seat to lock the adjusting seat and keep the position of the connecting bracket unchanged. The entire adjustment process is simple and quick to operate, realizing flexible adjustment of the center of gravity of the equipment, effectively reducing the risk of swaying, tilting and tipping caused by the shift of the center of gravity, and improving the stability of the equipment during operation.

[0048] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0049] Example 1,
[0050] See Figures 1 to 8 This utility model discloses an adjustment mechanism, including a connecting seat 10, an adjusting seat 20, and a first locking member 30. The connecting seat 10 is provided with a plurality of first limiting parts 11. The adjusting seat 20 is slidably disposed on the connecting seat 10 and can move on the connecting seat 10 along a first direction. The first locking member 30 is disposed on the adjusting seat 20 and is movably connected to the adjusting seat 20. The first locking member 30 is provided with a second limiting part 31. When the second limiting part 31 engages with one of the first limiting parts 11, the adjusting seat 20 is locked relative to the connecting seat 10. When the second limiting part 31 separates from the first limiting part 11, the adjusting seat 20 is unlocked relative to the connecting seat 10.
[0051] Based on the above structure, such as Figure 1 As shown, taking the first direction as the length direction of the connecting seat 10, the first limiting part 11 is a groove distributed at intervals on the connecting seat 10, and the second limiting part 31 is a protruding structure (such as a limiting block, limiting post, etc.) provided on the first locking member 30 that cooperates with the first limiting part 11 for limiting purposes, the following example will be used for explanation:
[0052] During assembly, the first locking member 30 is movably inserted through the vertical direction of the adjusting seat 20, such as sliding through the adjusting seat 20. An elastic structure (such as a spring) is provided between the first locking member 30 and the adjusting seat 20, or the first locking member 30 itself is made of an elastic material, providing a preload force to the first locking member 30 in the direction of the connecting seat 10. The first locking member 30 extends through the adjusting seat 20 to the end face of the connecting seat 10. When the adjusting seat 20 slides relative to the connecting seat 10 in the first direction, the second limiting part 31 will compress the elastic structure due to the pressure of the surface of the connecting seat 10. When it slides to a certain first limiting part 11 (groove), the preload force of the elastic structure will push the first locking member 30 down, causing the second limiting part 31 to automatically engage with the groove, forming a rigid limiting fit. At this time, the adjusting seat 20 and the connecting seat 10 are relatively fixed and locked.
[0053] If further adjustment is needed, the operator only needs to apply external force to the first locking member 30, causing it to move away from the connecting seat 10. This, in turn, causes the second limiting part 31 to move away from the first limiting part 11, disengaging the second limiting part 31 from the first limiting part 11 and unlocking the first locking member 30. After unlocking, the adjusting seat 20 can continue to slide relative to the connecting seat 10 along the first direction until it moves to the next first limiting part 11. The second limiting part 31 then forms a limiting engagement with the first limiting part 11 again. This process is repeated to achieve locking and unlocking of the adjusting seat 20 at different positions on the connecting seat 10, completing multi-level adjustment and meeting different adjustment needs.
[0054] Of course, in this embodiment, the first locking member 30 can also be connected to the adjusting seat 20 by rotation. Specifically, space is reserved on the adjusting seat 20 for rotation, and the first locking member 30 is hinged to the adjusting seat 20 by means of a pivot. In this assembly form, the first limiting part 11 is an arc-shaped groove on the connecting seat 10, and the second limiting part 31 is an arc-shaped protrusion on the first locking member 30 that matches the arc-shaped groove. When the adjusting seat 20 slides to the target position along the first direction, the first locking member 30, under its own weight (or a torsion spring can be added at the pivot to enhance the effect with the preload of the torsion spring), will have its end arc-shaped protrusion naturally inserted into the arc-shaped groove of the connecting seat 10. Due to the arc-shaped contact characteristics, the two form a circumferential limiting constraint. Combined with the lever structure of the pivot, the first locking member 30 "hooks" the connecting seat 10, restricting the adjusting seat 20 from sliding along the first direction, so that the adjusting seat 20 and the connecting seat 10 are relatively fixed.
[0055] If the position of the adjusting seat 20 needs to be adjusted, the user applies external force (such as pulling upward, pressing, etc.) to the part of the first locking member 30 exposed on the adjusting seat 20. The first locking member 30 rotates around the pivot, and the lever principle drives the arc-shaped protrusion to disengage from the arc-shaped groove. The second limiting part 31 separates from the first limiting part 11, and the adjusting seat 20 is released, and can be readjusted along the first direction. After the external force is released, if there is a torsion spring, the torsion spring will reset and push the first locking member 30 into the groove to lock again. If there is no torsion spring, the first locking member 30 can be manually pressed down to complete the engagement.
[0056] In addition, a locking structure (such as a spring plunger or a limit buckle) can be added to the adjusting seat 20. When the adjusting seat 20 is in the locked state, the structure can lock the first locking member 30 a second time, further improving the overall stability of the adjusting mechanism. Alternatively, a torsion spring can be added to the rotating shaft so that the arc-shaped protrusion and the groove are kept in contact by the torsion spring force when locked. When unlocking, the first locking member 30 is moved to compress the torsion spring. After being released, the torsion spring automatically resets and locks, enhancing the reliability of the lock.
[0057] Specifically, when the adjustment mechanism in this embodiment is applied to equipment such as cameras and film and television lighting equipment that require adjustment of the center of gravity, the connecting seat 10 can be fixedly connected to the equipment, and the adjustment seat 20 can be connected to the bracket or support mechanism used to fix the equipment. Since the adjustment seat 20 can achieve relative displacement with the connecting seat 10 in the first direction (i.e., the length direction of the connecting seat 10), the position of the bracket or support mechanism relative to the equipment can be dynamically adjusted in real time.
[0058] When it is necessary to adjust the center of gravity distribution of the equipment, the operator only needs to slide the adjusting seat 20 along the first direction to change the relative position of the equipment and the bracket or support mechanism, thereby achieving a redistribution of the center of gravity. After adjusting to the ideal position, by operating the first locking member 30, the second limiting part 31 and the corresponding first limiting part 11 on the connecting seat 10 form a limiting engagement, thereby locking the adjusting seat 20 and keeping the position of the bracket or support mechanism unchanged. The entire adjustment process is simple and quick to operate, and can flexibly adjust the center of gravity of the equipment, effectively reducing the risk of swaying, tilting and tipping caused by the shift in the center of gravity, and improving the stability of the equipment during operation.
[0059] It should be noted that the adjusting seat 20 and the connecting seat 10 can be connected in various ways to achieve sliding fit. For example, a sliding groove can be provided on the adjusting seat 20, and the sliding groove can be extended along the first direction. The connecting seat 10 can slide through the sliding groove along the first direction, so that the adjusting seat 20 can move stably along the length direction of the connecting seat 10. Alternatively, a slider can be provided at the bottom of the adjusting seat 20, and a corresponding sliding groove extending along the first direction can be provided on the connecting seat 10. The slider and the sliding groove can be matched, which can also realize the smooth sliding of the adjusting seat 20 along the length direction of the connecting seat 10.
[0060] Furthermore, the adjusting seat 20 is provided with a sliding groove 21 and a first through groove 22. The sliding groove 21 extends along a first direction, and the first through groove 22 extends along a second direction and passes through the sliding groove 21. The connecting seat 10 is slidably installed in the sliding groove 21, and the first locking member 30 is rotatably installed in the first through groove 22. The first limiting part 11 includes a limiting groove 111, and the second limiting part 31 includes a limiting protrusion 311. The limiting protrusion 311 is provided with a guide surface 312. The guide surface 312 slides and cooperates with the groove wall of the limiting groove 111 to guide the limiting protrusion 311 to slide into or out of the limiting groove 111.
[0061] Specifically, on the adjusting seat 20, a groove 21 extends along the first direction, and its groove shape (such as a dovetail groove or a T-groove) is adapted to the connecting seat 10, providing a linear sliding guide for the connecting seat 10 so that the adjusting seat 20 can move on the connecting seat 10 along a predetermined trajectory, thereby better controlling the center of gravity adjustment path. At the same time, the first through groove 22 penetrates the groove 21 vertically along the second direction (such as the vertical direction of the adjusting seat), forming a cross-shaped spatial channel. This layout ensures that the first locking member 30 will not interfere with the sliding action of the adjusting seat 20 when it rotates up and down. This not only ensures the displacement freedom of the adjusting seat 20 sliding along the first direction, but also provides the first locking member 30 with an independent rotation space, so that the two do not affect each other when working together and cooperate smoothly.
[0062] The first limiting part 11 is a limiting groove 111 spaced apart on the surface of the connecting seat 10 (which can be designed as an arc or rectangular groove according to requirements), and the second limiting part 31 is a limiting protrusion 311 at the end of the first locking member 30, and the side of the limiting protrusion 311 is machined with a guide surface 312 (such as an arc or inclined surface). When the adjusting seat 20 slides, if the first locking member 30 is in a "pre-locked" state (maintained in a downward state due to its own gravity), the guide surface 312 of the limiting protrusion 311 will first contact the surface of the connecting seat 10. With the help of the smooth transition characteristics of the inclined or curved surface, it will automatically push the first locking member 30 to rotate around the pivot and lift to avoid it, so that the adjusting seat 20 can slide smoothly. When the adjusting seat 20 slides to a certain limiting groove 111 position, the first locking member 30 falls back under the action of gravity. The guide surface 312 cooperates with the groove wall of the limiting groove 111, guiding the limiting protrusion 311 to smoothly lock into the limiting groove 111, completing the locking. When unlocking, simply move the first locking member 30, and the protruding guide surface 312 will slide and cooperate with the groove wall of the limiting groove 111, easily disengaging from the limiting groove 111, making the locking and unlocking operations smoother and less strenuous, and improving the overall adjustment efficiency.
[0063] Furthermore, the adjustment mechanism also includes a second locking member 40, which is mounted on the adjustment seat 20. In the locked state, the first locking member 30 and the second locking member 40 are engaged; in the unlocked state, the first locking member 30 and the second locking member 40 are separated.
[0064] Based on this structure, in the locked state, the second locking member 40 and the first locking member 30 are tightly engaged, forming a stable mechanical interlock structure. Even if the equipment encounters vibration or external impact, the rigid constraint of the second locking member 40 on the first locking member 30 reduces the risk of accidental unlocking due to inertia or shaking. This ensures that the equipment remains stable and reliable after the center of gravity adjustment, reducing operational malfunctions caused by center of gravity shift. When the center of gravity needs to be readjusted, simply releasing the engagement between the first locking member 30 and the second locking member 40 will release the adjusting seat 20.
[0065] Specifically, in this embodiment, the first locking member 30 and the second locking member 40 can be locked and unlocked using the following detachable connection method. For example, the first locking member 30 and the second locking member 40 can be connected by a snap-fit connection. During assembly, a slot or groove is provided at the end of the first locking member 30 near the second locking member 40, and a corresponding elastic buckle or protrusion is provided on the adjusting seat 20 as the second locking member 40. When the first locking member 30 locks the adjusting seat 20, its slot or groove will automatically engage with the buckle or protrusion of the adjusting seat 20 to form a secondary fixation. When unlocking, pressing the elastic buckle will disengage it from the slot or groove, thus separating the first locking member 30 and the second locking member 40.
[0066] Of course, the first locking member 30 and the second locking member 40 can also be connected by magnetic attraction. For example, a magnetic element (such as an iron sheet or a magnet) can be embedded at the end of the first locking member 30, and a magnet can be set at the corresponding position on the adjusting seat 20 as the second locking member 40. In the locked state, the magnetic element and the magnet are tightly attracted by magnetic force to prevent the first locking member 30 from rotating accidentally; when unlocking, an external force greater than the magnetic force is applied to push the first locking member 30 to separate the two, making the operation convenient.
[0067] Furthermore, the first locking member 30 includes a first end 32 and a second end 33. The first end 32 is rotatably connected to the adjusting seat 20. The second limiting part 31 is provided at the first end 32. The second locking member 40 is provided with a first stop part 41 and a second stop part 34 at the second end 33. In the locked state, the first stop part 41 and the second stop part 34 are engaged. In the unlocked state, the first stop part 41 and the second stop part 34 are separated.
[0068] Specifically, the first end 32 is the end of the first locking member 30 that is close to the connecting seat 10, and the second end 33 is the end that is away from the connecting seat 10. The first end 32 is rotatably connected to the adjusting seat 20 through a rotating shaft, so that the second end 33 can form a lever structure and rotate with the rotating shaft as the fulcrum. During assembly, the second limiting part 31 is provided on the first end 32, which is responsible for limiting and cooperating with the first limiting part 11 of the connecting seat 10 to directly lock the adjusting seat 20; and at the same time, the second stop part 34 is provided on the second end 33, which cooperates with the first stop part 41 of the second locking member 40 on the adjusting seat 20 to constrain the rotational movement of the first locking member 30 itself.
[0069] When the adjusting seat 20 slides to the target position along the first direction, the operator moves the second end 33 towards the first stop 41 (e.g., pressing down). At this time, the first end 32 rotates upward around the axis, driving the second limiting part 31 to gradually engage with the limiting groove 111 of the first limiting part 11. During this process, the second stop 34 of the second end 33 simultaneously approaches and engages with the first stop 41 of the second locking member 40. The engagement of the second limiting part 31 with the first limiting part 11 directly restricts the sliding of the adjusting seat 20, while the engagement of the first stop 41 with the second stop 34 constrains the rotational movement of the first locking member 30, preventing the first locking member 30 from loosening due to vibration or external force, so that the first limiting part 11 and the second limiting part 31 maintain a stable and reliable locking effect.
[0070] If the center of gravity needs to be readjusted, the operator first releases the constraint of the second locking member 40 to separate the first stop 41 and the second stop 34, so that the first locking member 30 resumes rotation. At this time, the second end 33 is moved away from the first stop 41 (such as by pulling upwards), and the first end 32 drives the second limiting part 31 to exit the limiting groove 111, thereby releasing the lock on the adjusting seat 20 and releasing the sliding function of the adjusting seat 20.
[0071] Preferably, in this embodiment, the second stop 34 is a limiting notch 341 provided at the second end 33 (e.g., Figure 6 As shown), the first stop 41 is a protrusion or block structure provided on the second locking member 40, and the limiting notch 341 is aligned with the first stop 41 in the first direction so as to achieve engagement or disengagement by means of locking.
[0072] More specifically, the second locking member 40 is movably connected to the adjusting seat 20 via the first elastic member 50 (such as a spring or a sheet-like spring). The first elastic member 50 always applies an elastic force toward the second stopping part 34 to the second locking member 40, driving the first stopping part 41 to continuously maintain a tendency to approach the second stopping part 34.
[0073] When locking the adjusting seat 20 is required, the operator rotates the second end 33 of the first locking member 30, causing the second stop 34 to rotate towards the first stop 41. During rotation, the end wall of the second stop 34 gradually presses against the contact surface of the first stop 41, forcing the first stop 41 to overcome the elastic force and move away from the second stop 34. At the same time, the first elastic member 50 is compressed. When the second stop 34 rotates to a preset angle, the limiting notch 341 on the second stop 34 aligns with the first stop 41. The first elastic member 50 instantly releases its elastic potential energy, pushing the first stop 41 to rebound and engage with the limiting notch 341 of the second stop 34. At this time, the continuous elastic force of the first elastic member 50 ensures that the first stop 41 and the second stop 34 are always tightly fitted. Even if the equipment experiences vibration, the elastic force can compensate for small gaps, reducing the risk of the second stop 34 accidentally disengaging and keeping the first locking member 30 in a stable locked state.
[0074] When unlocking is required, the operator applies external force to the second locking member 40, pushing the first stop 41 to overcome the elastic force and compress the first elastic member 50 again, causing the first stop 41 to disengage from the limiting groove 111 of the second stop 34. At this time, the first locking member 30 resumes rotation, and the operator can rotate the second end 33 in the opposite direction to drive the second limiting part 31 to disengage from the first limiting part 11, thus completing the unlocking.
[0075] It should be noted that during assembly, one end of the first elastic member 50 is connected to the end of the second locking member 40 away from the first locking member 30, and the other end of the first elastic member abuts against the inner wall of the adjusting seat 20 to provide axial elastic force to the second locking member 40.
[0076] In addition, the top of the second locking member 40 is provided with a limiting buckle 42, which extends out of the edge of the adjusting seat 20. The limiting buckle 42 provides a convenient point of force application for the operator. When unlocking is required, the user does not need to go deep into the adjusting seat 20. He only needs to apply a lateral or longitudinal external force (such as fingertip pressing or thumb flicking) to the limiting buckle 42 on the outside of the adjusting seat 20. The limiting buckle 42 will drive the second locking member 40 to move as a whole, so that the first stop 41 overcomes the elastic compression spring of the first elastic member 50 and moves away from the second stop 34 and disengages from the limiting engagement. This improves the convenience and efficiency of the unlocking operation.
[0077] Furthermore, the adjusting seat 20 is also provided with a second elastic element 23, which provides an elastic force to drive the second end 33 to rotate away from the adjusting seat 20.
[0078] Specifically, when the first stop 41 and the second stop 34 are engaged, the second end 33 of the first locking member 30 is in a downward swinging position due to pressure. At this time, the second elastic member 23 is compressed synchronously and stores elastic potential energy. When the first stop 41 and the second stop 34 are separated (the second locking member 40 is released from constraint), the elastic potential energy stored in the second elastic member 23 is quickly converted into kinetic energy, driving the second end 33 of the first locking member 30 to automatically flip upward to a preset angle, so that the second end 33 is naturally exposed in the operating area of the adjustment seat 20. The operator does not need to search for or pry open the hidden parts, and can directly and easily hold the non-slip handle of the second end 33 with their fingers, reducing the difficulty of operation.
[0079] It should be noted that the second elastic element 23 can be a spring, an elastic column (such as a rubber column), or a spring sheet, etc., provided on the adjusting seat 20.
[0080] More specifically, the second end 33 is also provided with a gripping part 35, which extends out of the edge of the adjusting seat 20, forming a clear operating fulcrum. In conjunction with the second elastic element 23 driving the second end 33 to flip upward, the operator can more easily find the point of force application, quickly position and grip the second end 33.
[0081] In addition, the grip portion 35 is also provided with a grip groove 351. The shape of the groove conforms to the contour of the fingers (such as an arc-shaped groove that fits the thumb and index finger), which can increase the contact area between the fingers and the grip portion 35. At the same time, the side wall of the groove restricts finger slippage. Even when the hands are sweaty or when operating with gloves, the risk of slippage can be effectively reduced, so that the applied external force can be effectively transmitted to the second end 33, reducing the probability of operation errors caused by improper force.
[0082] Furthermore, the top and bottom of the connecting seat 10 are provided with a plurality of first limiting parts 11; the adjustment mechanism also includes a third locking member 60 and a third elastic member 70. The adjusting seat 20 is provided with a second through groove 24 opposite to the first through groove 22. The second through groove 24 passes through the adjusting seat 20 and communicates with the connecting seat 10; the third locking member 60 is installed in the second through groove 24 through the third elastic member 70. The third elastic member 70 provides an elastic force to drive the third locking member 60 to cooperate with the first limiting part 11 located at the bottom of the connecting seat 10.
[0083] Specifically, when the adjusting seat 20 and the connecting seat 10 are locked, the top second limiting part 31 is embedded into the top first limiting part 11 of the connecting seat 10, and the bottom third locking part 60 is engaged into the bottom first limiting part 11 of the connecting seat 10 under the pushing force of the third elastic part 70 (such as a spring or elastic column). The two apply clamping forces from the top and bottom directions respectively, making the contact surfaces of the adjusting seat 20 and the connecting seat 10 more tightly connected, effectively offsetting the overturning moment caused by the shift of the center of gravity of the equipment (such as the downward pressure at the front end when a camera is mounted with a telephoto lens), avoiding local stress concentration caused by locking in one direction, and reducing the wear rate of the connecting seat 10 and the adjusting seat 20.
[0084] Furthermore, if the top first locking member 30 becomes slightly loose due to vibration or operational error, the bottom third locking member 60 can maintain the locked state through the continuous thrust of the third elastic member 70, preventing the adjusting seat 20 from slipping off instantly; conversely, if a gap appears in the bottom locking, the top locking can still provide basic constraint. This bidirectional locking structure enhances the stability and adaptability of the adjusting mechanism from multiple dimensions.
[0085] More specifically, the second through groove 24 and the first through groove 22 are arranged opposite each other in the second direction (the vertical direction of the adjustment seat), so that the action of the third locking member 60 is mirrored and coordinated with the first locking member 30. When unlocking, the top first locking member 30 disengages, and the bottom third locking member 60 can automatically avoid the third elastic member 70 during the sliding of the adjustment seat 20 (similar to the function of the top guide surface 312). After sliding to the target position, it can automatically lock into the bottom first limiting part 11 under the action of elastic force. Bidirectional locking can be completed without additional operation, taking into account both convenience and stability.
[0086] It should be noted that the third locking member 60 can be formed into a block-shaped, column-shaped, or elastic buckle structure that adapts to the groove on the first limiting part 11. During assembly, a spring groove can be formed at one end of the third locking member 60 near the bottom of the second through groove 24, one end of the third elastic member 70 can be embedded in the groove and fixed, and the other end can abut against the inner wall of the second through groove 24. Alternatively, both ends of the third elastic member 70 can be connected to the bottom of the third locking member 60 and the bottom of the second through groove 24 respectively, both of which can achieve the above effect. The specific design can be based on the actual application.
[0087] Example 2,
[0088] See Figure 1 A film and television device includes a main body 80, a connecting bracket 90, and an adjustment mechanism. The connecting seat 10 is connected to the main body 80, and the adjustment seat 20 is connected to the connecting bracket 90.
[0089] Specifically, the connecting seat 10 is fixedly connected to the equipment body 80, and the adjusting seat 20 is connected to the connecting bracket 90. Since the adjusting seat 20 can achieve relative displacement with the connecting seat 10 in the first direction (i.e. the length direction of the connecting seat 10), the position of the connecting bracket 90 relative to the equipment body 80 can be dynamically adjusted in real time.
[0090] When it is necessary to adjust the center of gravity distribution of the main body 80, the operator only needs to slide the adjusting seat 20 along the first direction to change the relative position of the main body 80 and the connecting bracket 90, thereby achieving a redistribution of the center of gravity. After adjusting to the ideal position, by operating the first locking member 30, the second limiting part 31 and the corresponding first limiting part 11 on the connecting seat 10 form a limiting engagement, thereby locking the adjusting seat 20 and keeping the position of the connecting bracket 90 unchanged. The entire adjustment process is simple and quick to operate, and can flexibly adjust the center of gravity of the main body 80, effectively reducing the risk of shaking, tilting and tipping caused by center of gravity shift, and improving the stability of the film and television equipment during operation.
[0091] It should be noted that the connecting seat 10 can be detachably connected to the main body 80 of the equipment by means of nuts, bolts and other connecting parts, while the adjusting seat 20 can be detachably connected and fixed to the connecting bracket 90 by means of snap-fit connection or threaded connection, so as to facilitate disassembly and assembly for later maintenance.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
