A truss fixing assembly is mounted on the crossbeam. The truss fixing assembly includes a U-shaped base. A pressure plate is hinged to the free end of one ear plate segment of the base, and an adjusting screw is hinged to the free end of the other ear plate segment. A limit nut is screwed onto the adjusting screw. The free end of the pressure plate is sleeved on the free end of the adjusting screw. The limit nut abuts against the upper surface of the pressure plate, and the inner surface of the pressure plate abuts against the outer surface of the truss fittings. A connector for connecting to film and television equipment is provided below the crossbeam. Due to the truss fixing assembly, it can be fixedly connected to trusses of different diameters, improving the adaptability of the device and making it suitable for industrial production with strong practicality.

[0003] In the past, film and television equipment often required rotation and adjustment in different directions after it was set up. Therefore, this solution aims to propose an adjustable hook for film and television equipment that can still be horizontally rotated to adjust the position of the camera after it is fixed. Utility Model Content

[0004] The technical problem this invention aims to solve is how to achieve rotational adjustment of the installed film and television equipment in order to complete image acquisition from all directions. To improve its shortcomings, this invention provides an adjustable hook for film and television equipment.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: due to the cooperative arrangement of the rotating toothed disc and the arc-shaped toothed ring, the limiting relationship between the rotating toothed disc and the arc-shaped toothed ring can be changed by rotating the adjustable bolt, thereby enabling the mounting plate to be rotated and adjusted in position after the audio-visual equipment is installed. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the hook body includes a hook seat rotatably connected to the mounting plate. The hook seat is U-shaped, and the inner surface of the middle section of the hook seat is concave. A pawl is hinged to the free end of one ear plate section of the hook seat, and a groove is formed at the free end of the pawl. A pin is hinged to the other ear plate section of the hook seat, and a screw is integrally provided on the pin. The free end of the screw passes through the groove and is fitted with a limiting sleeve. The bottom of the limiting sleeve abuts against the upper surface of the pawl, and a locking bolt is screwed onto the free end of the screw protruding from the limiting sleeve.

[0009] As a preferred embodiment, the upper surfaces of the claws located on both sides of the groove are provided with concave planes, and the bottom of the limiting sleeve abuts against the concave planes.

[0010] As a preferred embodiment, the upper surface of the mounting plate is provided with several connection holes for connecting to external audio-visual equipment.

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, an adjustable hook for film and television equipment includes a mounting plate 1. A rotating gear plate 2 is rotatably connected to the bottom of the mounting plate 1. An adjusting seat 3 is fixedly connected to the bottom of the mounting plate 1 on the side of the rotating gear plate 2. An adjustable bolt 4 is screwed into the adjusting seat 3. An arc-shaped gear ring 5 is connected to the free end of the adjustable bolt 4. Specifically, the adjustable bolt 4 is rotatably connected to the adjusting seat 3. The root of the arc-shaped gear ring 5 is provided with an internal thread. The free end of the adjustable bolt 4 is screwed into the internal thread. The arc-shaped gear ring 5 is engaged with the rotating gear plate 2. Hook bodies 6016 are rotatably connected to both sides of the upper surface of the mounting plate 1. The hook body 6016 includes a hook seat 601 rotatably connected to the mounting plate 1. The hook seat 601 is U-shaped, and the inner surface of the middle section of the hook seat 601 is concave. A pawl 602 is hinged to the free end of one ear plate section of the hook seat 601. The free end of the pawl 602 has a groove 603. A pin 604 is hinged to the other ear plate section of the hook seat 601. A screw 605 is integrally provided on the pin 604. The free end of the screw 605 passes through the groove 603 and is fitted with a limiting sleeve 606. The bottom of the limiting sleeve 606 abuts against the upper surface of the pawl 602. A locking bolt 607 is screwed onto the free end of the screw 605 protruding from the limiting sleeve 606. The upper surfaces of the pawls 602 located on both sides of the groove 603 have concave planes 608, and the bottoms of the limiting sleeves 606 abut against the concave planes 608. The upper surface of the mounting plate 1 has several connection holes 7 for connecting to external audio-visual equipment. The bottom of the mounting plate 1 is integrally provided with a fixing base 8.

[0017] During operation, the operator can mount the video equipment, such as a camera, on the connection hole 7 on the upper surface of the mounting plate 1. After fixing, rotate the adjustable bolt 4. When rotating the adjustable bolt 4, the arc-shaped gear ring 5 moves towards the rotating gear disk 2, causing the arc-shaped gear ring 5 to engage with the rotating gear disk 2. At this time, the mounting plate 1 and the rotating gear disk 2 are in a limited position. When rotating the adjustable bolt 4, the arc-shaped gear ring 5 moves away from the rotating gear disk 2, causing the arc-shaped gear ring 5 to disengage from the rotating gear disk 2. At this time, the mounting plate 1 and the rotating gear disk 2 are in an unlocked state, and the mounting plate 1 and the rotating gear disk 2 can rotate relative to each other, thereby facilitating the adjustment of the rotation direction.

[0018] The hook body 6016 can be used to lock the pipe fittings. After the pipe fittings are locked, the film and television equipment can be installed on the pipe fittings, thus realizing another way of installing the film and television equipment on the device.

[0019] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
