Description

Technical Field

[0001] This utility model belongs to the technical field of tracking stick accessories, specifically relating to a ZY axis dovetail pressure block for a tracking stick. Background Technology

[0002] During use, tracking sticks often require frequent switching between vertical and horizontal shooting and tilting and panning angle adjustments. This typically necessitates dynamic adjustment of the fixed locking structure, and maintaining shooting posture stability during dynamic tracking such as running requires high stability of the fixed locking structure. Existing tracking sticks often use ordinary screws or simple clips for adjustable locking structures. However, ordinary screw locking relies on single-point compression for fixation, which can lead to concentrated force and localized wear. Simple clips are partial locking structures, and during adjustment, the connecting arm or gimbal can easily tip over due to momentary weightlessness, causing equipment damage. Furthermore, their locking stability is poor, making it difficult to simultaneously meet the requirements of good connection stability and easy adjustment. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems by providing a ZY-axis dovetail pressure block for a tracking stick, thereby resolving the problems mentioned above.

[0004] This utility model is achieved through the following technical solution: a ZY-axis dovetail pressure block for a tracking stick, comprising a first plate and a second plate stacked in an alternating manner, with the extension direction of the overlapping part of the first plate and the second plate as the Y-axis, a fixing hole through the center of the second plate along the Z-axis direction, support columns extending downward from both ends of the lower surface of the second plate, a fixing groove formed on the lower surface of the support columns, an inwardly recessed arc-shaped edge on the side wall of the first plate near the second plate, the arc-shaped edge being concentric with the fixing hole, and the lower surface of the first plate being an inclined surface relative to the side wall of the second plate, the angle between the inclined surface and the side wall of the second plate being greater than 90° and less than 180°.

[0005] Furthermore, the angle between the inclined plane and the sidewall of the second plate is 135°±0.3°.

[0006] Furthermore, the first and second panels are formed as a single unit.

[0007] Furthermore, a U-shaped limiting step is provided at the perimeter of the fixing hole, and the horizontal height of the two ends of the upper surface of the second plate is greater than the horizontal height of the perimeter of the fixing hole.

[0008] Furthermore, the opening of the U-shaped limiting step faces a direction relatively away from the first plate, and both ends of the opening of the U-shaped limiting step are provided with arc-shaped chamfers.

[0009] This utility model forms a relatively stable triangular support when fixed with the corresponding accessories by setting a fixing hole and two fixing slots, which has good connection stability. Compared with the existing fixing and locking structure, the adjustment method is simple. When the support of the bottom top rod and fixing slot weakens, the threaded rod above pulls and supports it, thus avoiding the risk of the top gimbal losing weight and bumping during the adjustment process. It can take into account both the needs of good connection stability and easy adjustment. Attached Figure Description

[0012] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0013] like Figures 1-4 As shown, this utility model describes a ZY-axis dovetail pressure block for a tracking stick, comprising a first plate 1 and a second plate 2 arranged in an alternating stacked manner. The extension direction of the overlapping part of the first plate 1 and the second plate 2 is taken as the Y-axis. A fixing hole 21 is provided at the center of the second plate 2 and is provided through the Z-axis. Support columns 22 extend downward from both ends of the lower surface of the second plate 2. The lower surface of the support column 22 is provided with a fixing groove 221. The side wall of the first plate 1 near the second plate 2 is provided with an inwardly recessed arc-shaped edge 11. The arc-shaped edge 11 and the fixing hole 21 are concentrically arranged. The lower surface of the first plate 1 is an inclined surface 12 that is inclined relative to the side wall of the second plate 2. The angle between the inclined surface 12 and the side wall of the second plate 2 is greater than 90° and less than 180°.

[0014] During installation, place the ZY-axis dovetail block of this invention at the junction of the top gimbal and the connecting arm of the tracking stick. The adjustable push rod abuts against the fixing groove 221. First, align the connecting arm with the lower end of the ZY-axis dovetail block, then align the top gimbal of the tracking stick with the upper end of the ZY-axis dovetail block. A fastener can pass through the fixing hole 21 and be fixed to the connecting arm. The fastener can be a threaded rod with a knob or similar accessory. The arc-shaped edge 11 on the side wall of the first plate 1 provides clearance for the threaded rod. When the fastener and fixing hole 21 are fully pressed together, the top gimbal remains relatively horizontal. When adjusting the tilt angle of the top gimbal to adjust the shooting angle, first loosen the fastener to allow relative movement between the top gimbal, the ZY-axis dovetail block, and the connecting arm. Then, adjust and increase the length of the push rod to re-secure it tightly against the fixing groove 221, providing support for the second plate 2. Since the first plate 1 and the second plate 2 are stacked in a similar Z-shape, when the lower end of the second plate 2 is subjected to force, and because the lower surface of the first plate 1 is inclined 12 to form a clearance, the ZY axis dovetail pressure block rotates and tilts along the Y axis. In other words, the ZY axis dovetail pressure block and the top gimbal of the tracking stick swing relative to each other, thereby adjusting the shooting angle of the camera. During the adjustment process, the user can lift the top gimbal with one hand to form support, and adjust the threaded rod and the top rod in sequence with the other hand. When the fixing hole 21 and the two fixing grooves 221 are fixed with the corresponding accessories, they form a relatively stable triangular support with good connection stability. Compared with the existing fixing and locking structure, the adjustment method is simple. When the support of the bottom top rod and fixing groove 221 weakens, the threaded rod above pulls and supports it, thus avoiding the risk of the top gimbal losing weight and bumping during the adjustment process. It can take into account both the needs of good connection stability and easy adjustment.

[0015] In this embodiment of the present invention, the included angle between the inclined surface 12 and the side wall of the second plate 2 is preferably 135°±0.3°. This angle setting provides the optimal clearance space for the ZY axis dovetail pressure block to rotate and tilt along the Y axis, which can avoid rotational interference caused by too small an angle, ensure that the top gimbal can swing smoothly when adjusting the shooting angle, and prevent structural redundancy caused by too large an angle, thus ensuring the overall compactness of the pressure block structure.

[0016] In this embodiment of the utility model, the first plate 1 and the second plate 2 are integrally formed. The integral forming setting can effectively ensure the connection stability of the first plate 1 and the second plate 2, improve the overall structural strength and rigidity of the ZY axis dovetail pressure block, and ensure that it maintains a stable structural shape when bearing the load of the top gimbal and camera and repeatedly rotating and adjusting along the Y axis, avoiding fatigue damage caused by stress concentration and extending the service life of the product.

[0017] In this embodiment of the invention, a U-shaped limiting step 23 is provided at the periphery of the fixing hole 21. The horizontal height of the two ends of the upper surface of the second plate 2 is greater than the horizontal height of the periphery of the fixing hole 21. The U-shaped limiting step 23 forms a limiting space that matches the knob, which can position the knob at the upper end of the threaded rod. Combined with the visual and physical guiding structure formed by the height difference between the two ends of the upper surface of the second plate 2, the user does not need to repeatedly calibrate the relative position of the knob and the fixing hole 21 during assembly or adjustment. The knob can be quickly inserted into the limiting area based solely on the outline of the U-shaped step, realizing the rapid alignment of the knob and the fixing hole 21, reducing the difficulty and time cost of alignment operation.

[0018] In this embodiment of the utility model, the opening of the U-shaped limiting step 23 faces a direction relatively away from the first plate 1. The two ends of the opening of the U-shaped limiting step 23 are provided with arc-shaped chamfers 231, which can avoid the first plate 1 from obstructing the operating space during the alignment and insertion of the knob, and provide sufficient clearance for the user's hand and the knob. Especially in the compact assembly environment where the gimbal at the top of the tracking stick is connected to the connecting arm, it can reduce the operational interference when the knob is aligned, making it easier for the user to quickly observe and insert the knob into the U-shaped limiting step 23, and improving the convenience of assembly and adjustment.

[0019] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
