Description

Technical Field

[0001] The present application relates to the technical field of reflective panels, and more specifically, to an adjustable reflective panel bracket for news dissemination. Background Art

[0002] Journalism and communication includes news and communication, advertising, network and new media, journalism, communication, radio and television, editing and publishing, news photography, etc. With the rapid development of the Internet, the live broadcast and short video industries have emerged. During the shooting process, it is often necessary to use off-site equipment such as microphones and reflectors to increase the user experience of the video. Among them, the reflector is a commonly used lighting auxiliary tool during shooting. Using the reflector according to the needs of the environment can make the plain picture fuller and reflect a good image light and texture. In addition, using the reflector to appropriately change the light in the picture is also very effective in simplifying the picture components and highlighting the subject; at the same time, the reflector fills in the light softly and will not cause the sharpness caused by the flash fill.

[0003] Traditional reflectors are mainly handheld, which causes arm pain for operators who hold handheld reflectors after long-term shooting operations; at the same time, traditional reflectors lack specific adjustment mechanisms to adjust the height and display angle of the reflectors, and there is also a technical problem of being difficult to carry. In response to the above problems, the relevant technology provides a more optimized solution: for example, the patent with authorization announcement number CN219872069U discloses a reflector for news dissemination. The patent uses an adjustable movable connection structure between the horizontal connecting column and the vertical movable column, and between the movable column and the base, so that the reflector can stand naturally at the shooting scene, solving the problem of arm pain caused by handheld reflectors. At the same time, the new reflector has a variety of display angles, a high degree of freedom, and strong operability.

[0004] With respect to the above-mentioned related technologies, the applicant has found the following problems: the base of the above-mentioned reflector is mainly of turntable type, which requires that the environment where it is placed has less debris on the ground and is relatively stable. However, in a video shooting environment with relatively complete equipment, the ground lines are often relatively complicated, and the placement environment of the reflector has certain limitations; and the conventional bracket-type reflector has an unadjustable base and can generally only be fixed when it is opened to the maximum. When there are requirements for the lighting position and there are objects at the bottom of the bracket that are difficult to move, the bracket is also difficult to fix, so the environmental adaptability is still poor.

[0005] Therefore, it is necessary to propose a reflector bracket for news dissemination with strong environmental adaptability to solve the technical problems in the related art. Utility Model Content

[0006] In order to solve the technical problem of poor environmental adaptability of reflector brackets in related technologies, the present application provides an adjustable reflector bracket for news dissemination, which utilizes the cooperation between the support rod and the adjustment component to achieve controllable opening and closing angles of the support rod, greatly increasing the environmental adaptability of the reflector.

[0007] The adjustable reflector bracket for news dissemination provided in the present application adopts the following technical solution:

[0008] An adjustable reflector bracket for news dissemination, comprising a cross bar, a reflector frame, an upright bar and a first tightening assembly, wherein the upright bar is connected to the cross bar via the first tightening assembly, and one end of the cross bar away from the upright bar is fixedly connected to the reflector frame, and further comprising a supporting mechanism; the supporting mechanism comprises at least three support rods, a second tightening assembly and a fixing tube, wherein the upright rod is slidably connected in the fixing tube and fixed by the second tightening assembly; the side wall of the fixing tube is dampingly hinged to the top end of the support rod, and at least three of the support rods are arranged in a circular array around the axis of the fixing tube; and an adjusting mechanism for fixing the support rod is provided on the fixing tube.

[0009] By adopting the above technical solution, the vertical rod and the horizontal rod cooperate to realize the lifting and lowering of the bracket. The horizontal rod and the vertical rod are connected by a first tightening assembly to ensure that the bracket has good adjustment freedom here; in addition, through the damping hinge between the support rod and the fixed tube, and the cooperation between the adjustment mechanism and the support rod, the opening and closing degree of the support rod can be controlled, thereby increasing the environmental adaptability of the support rod.

[0010] In a specific feasible implementation scheme, a hinge seat corresponding to the support rod is fixedly connected to the outer peripheral wall of the fixed cylinder; the top of the support rod is hinged to the hinge seat for damping rotation by relying on a rotating shaft; the adjustment mechanism includes a turntable and a drive assembly for controlling the rotation of the turntable; the turntable is coaxially rotatably connected to the fixed cylinder, and a connecting plate corresponding to the hinge seat is provided under the turntable, and an arc-shaped clamping rod is fixedly connected to the side wall of each connecting plate, a plurality of arc-shaped clamping grooves are provided in a circular array around the rotating shaft at the top of the support rod, and clamping holes are relatively provided on the hinge seat, and the arc-shaped clamping rod is intermittently engaged with the arc-shaped clamping groove and the clamping hole.

[0011] By adopting the above technical solution, when the operator places the bracket for different environments, he first adjusts the opening and closing range of the support rod appropriately. During the adjustment process, the support rod and the fixed tube are damped and hinged, so they will not swing in a natural state; after the adjustment is completed, the operator drives the turntable to rotate through the driving assembly, so that the arc-shaped clamping rod is embedded in the arc-shaped clamping groove and the clamping hole, and the bracket is further fixed. This ensures that when the ground wiring is messy or there are immovable objects, the bracket can also be upright, thereby ensuring smooth lighting.

[0012] In a specific implementation scheme, the end of the arc-shaped clamping rod that is embedded in the clamping hole and the arc-shaped clamping slot is a head, and a limiting plate is fixedly connected to the arc-shaped clamping rod, and the distance from the limiting plate to the arc-shaped clamping rod head is greater than the distance between the two clamping holes.

[0013] By adopting the above technical solution, the limiting piece can ensure that the arc-shaped clamping rod is completely clamped into the hinge seat.

[0014] In a specific feasible implementation scheme, the driving assembly includes an arc-shaped rack and a driving gear, and the second tightening assembly includes a locking bolt; the arc-shaped rack is fixedly connected to the top surface of the turntable, the driving gear and the arc-shaped rack are meshed, the driving gear is sleeved on the locking bolt and is rotatably connected to the locking bolt, a threaded hole is provided on the side wall of the fixed cylinder, the locking bolt is threadedly matched with the threaded hole and presses the driving gear against the fixed cylinder, and the end of the locking bolt is used to press against the vertical pole.

[0015] By adopting the above technical solution, when adjusting the opening and closing of the support rod, the locking bolt is loosened and the arc-shaped clamping rod is located outside the hinged seat; after the opening and closing degree of the support rod is adjusted, the operator rotates the driving gear on the premise of loosening the locking bolt, and the driving gear drives the driving rack to rotate, thereby driving the turntable to rotate, and then the arc-shaped clamping rod is embedded in the arc-shaped clamping groove and the clamping hole, completing the clamping and limiting of the support rod.

[0016] In a specific possible implementation scheme, a lever is fixedly connected to the bolt head of the locking bolt, and the length direction of the lever is the same as the radial direction of the locking bolt.

[0017] By adopting the above technical solution, the lever makes it more convenient and labor-saving for the operator to turn the locking bolt.

[0018] In a specific possible implementation manner, the distance from the top of the support rod to the bottom of the fixed tube is not greater than half the length of the support rod.

[0019] In a specific possible implementation mode, an elastic member for retracting the support rods is connected between the fixing tube and each support rod.

[0020] In a specific feasible implementation scheme, a hook ring is provided on the side wall of the fixing tube below the hinged end of the support rod, and a curved hook is provided on the side wall of the support rod facing the fixing tube. The elastic member includes a spring, and the two ends of the spring are respectively hooked on the hook ring and the curved hook; when the support rod is folded, the spring is in a stretched state.

[0021] To sum up, the present application has the following beneficial effects: the present application realizes the controllable opening and closing degree of the support rod through the cooperation of the adjustment mechanism with the hinge seat and other components, increases the environmental adaptability of the bracket, is suitable for a variety of complex lighting environments, has low requirements for ground lines, etc., has strong adjustability and strong lighting stability.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 The present application is further described in detail with reference to the accompanying drawings and embodiments.

[0030] Example

[0031] This embodiment requests to disclose an adjustable news dissemination reflector bracket, referring to Figure 1 The utility model discloses a light-reflecting device, which comprises a cross bar 1, a reflector frame 2, an upright pole 3 and a first tightening assembly 4. The upright pole 3, the cross bar 1, the reflector frame 2 and the first tightening assembly 4 have no obvious difference from the corresponding parts in the prior art. Specifically, the cross bar 1 can slide along its own length direction and is rotatably connected with the upright pole 3 through the first tightening assembly 4. The first tightening assembly 4 is used to fix the cross bar 1 on the upright pole 3 and can tighten and fix the cross bar 1 to limit the sliding of the cross bar 1. One end of the cross bar 1 away from the upright pole 3 is fixedly connected with the reflector frame 2. The reflector frame 2 is used to cover and fix the reflector. A support rod for support can also be added in the reflector frame 2.

[0032] Specifically, the first tightening assembly 4 may be Figure 2The structure shown: the first tightening assembly 4 includes two damping hinged connecting frames 41, and the ends of each connecting frame 41 are provided with fixing plates 42 opposite to each other. One connecting frame 41 is sleeved on the vertical pole 3, and the other connecting frame 41 is sleeved on the cross bar 1. The two adjacent fixing plates 42 are fixed by bolts. Loosening the bolts can realize the rotation and sliding of the cross bar 1 itself, as well as the rotation of the cross bar 1 relative to the vertical pole 3. It has a high degree of freedom and is easy to adjust.

[0033] The reflector bracket also includes a support mechanism 5 located at the bottom of the vertical pole 3; the support mechanism 5 includes three support rods 51, three second tightening components and a fixed tube 53; the tube mouth of the fixed tube 53 faces upward, the vertical pole 3 is inserted into the fixed tube 53 and is slidably connected with the fixed tube 53, the second tightening component fixes the vertical pole 3 in the fixed tube 53, thereby limiting the lifting and lowering of the vertical pole 3, the second tightening component includes a tightening bolt, a tightening threaded hole is provided on the side wall of the fixed tube 53, the tightening bolt is threadedly connected with the tightening threaded hole and tightens the vertical pole 3; the three support rods 51 are distributed in a circumferential array on the outer wall of the fixed tube 53, and the top of the support rod 51 is damped and hinged with the outer wall of the fixed tube 53, so that the support rod 51 can rotate in a direction perpendicular to its own length, thereby adjusting the opening and closing degree of the three support rods 51 and increasing its environmental adaptability. Correspondingly, an adjustment mechanism 6 for adjusting the support rods 51 and fixing the support rods 51 is also provided on the outer wall of the fixed tube 53.

[0034] In order to increase the stability of the bracket, the distance from the top of the support rod 51 to the bottom of the fixed tube 53 is not greater than half the length of the support rod 51. When the three support rods 51 are fully opened, the bottom of the fixed tube 53 abuts against the ground. At this time, the angle between the axis of the support rod 51 and the fixed tube 53 is greater than or equal to 60°, and the stability is better.

[0035] In order to ensure that the opening and closing range of the support rod 51 is controllable, the present application also adopts the following design: three array-distributed hinge seats 531 are fixedly connected to the outer peripheral wall of the fixed cylinder 53, and the hinge seats 531 are used to be hinged to the support rods 51 one by one. The specific hinge method is: the top of the support rod 51 is hinged in the hinge seat 531 through a rotating shaft, and the shape of the hinge seat 531 is approximately "C" shaped. The top of the support rod 51 is hinged in the hinge seat 531 by means of a gasket or a rubber ring; correspondingly, the adjustment mechanism 6 includes a turntable 61 and a drive assembly, and the turntable 61 is coaxially rotatably connected to the outer side wall of the fixed cylinder 53, and the connection position is located above the top of the support rod 51; three "L"-shaped connecting plates 612 are fixedly connected below the turntable 61, and the connecting plates 612 are connected along Figure 5 , Figure 6The clockwise side is fixedly connected with an arc-shaped clamping rod 611, and the arc of the arc-shaped clamping rod 611 is the same as the circumference of the rotating disk 61; the top of the support rod 51 is provided with a plurality of arc-shaped clamping grooves 511 adapted to the arc of the arc-shaped clamping rod 611, and the plurality of arc-shaped clamping grooves 511 surround the rotating shaft and are arranged in a circular array; the opposite side walls of the hinge seat 531 are provided with clamping holes 533, and as the rotating disk 61 rotates, the arc-shaped clamping rod 611 can be engaged with the arc-shaped clamping grooves 511 and the clamping holes 533, thereby limiting the rotation of the support rod 51. The above-mentioned driving assembly is used to drive the rotation of the rotating disk 61 more conveniently.

[0036] Furthermore, in order to ensure that the arc-shaped clamping rod 611 can completely pass through the hinge seat 531 and the top of the support rod 51, the end of the arc-shaped clamping rod 611 of the present application that is clamped into the clamping hole 533 and the arc-shaped clamping groove 511 is the head, and the side wall of the arc-shaped clamping rod 611 near the tail can be vertically fixedly connected with a limiting plate, and the distance from the limiting plate to the head of the arc-shaped clamping rod 611 is greater than the distance between the two clamping holes 533, so as to ensure that the arc-shaped clamping rod 611 can freely pass through the hinge seat 531 and be limited by the limiting plate. It is also possible to adopt the scheme of this embodiment: the length of the arc-shaped clamping rod 611 is slightly greater than the sum of twice the depth of the clamping hole 533 and the length of the arc-shaped clamping groove 511, so as to ensure that the arc-shaped clamping rod 611 can be completely clamped, and at this time the connecting plate 612 plays the role of the above-mentioned limiting plate.

[0037] The above-mentioned driving assembly is located above the turntable 61. Specifically, the driving assembly includes an arc-shaped rack 621 and a driving gear 622. The second tightening assembly includes a locking bolt 521. The locking bolt 521 is equivalent to the tightening bolt mentioned above. One of its functions is to fix the vertical rod 3 to the fixed tube 53; the arc-shaped rack 621 is fixedly connected to the top surface of the turntable 61; the arc corresponding to the arc-shaped rack 621 is the same as the arc of the outer wall of the turntable 61; the driving gear 622 is located at the top of the arc-shaped rack 621, and the driving gear 622 is meshed with the arc-shaped rack 621; the driving gear 622 is sleeved on the locking bolt 521 and is rotatably connected to the locking bolt 521; a threaded hole is provided on the side wall of the fixed tube 53, and the locking bolt 521 passes through the driving gear 622 and is threadedly connected to the threaded hole, thereby tightening the driving gear 622 to the fixed tube 53. Furthermore, in order to facilitate the operator to manually tighten the locking bolt 521 , a lever 522 is fixedly connected to the bolt head of the locking bolt 521 of the present application, and the length direction of the lever 522 is perpendicular to the length direction of the locking bolt 521 .

[0038] It should be noted that the top of the support rod 51 can also be locked and fixed to the fixed tube 53 by some conventional technical means, such as by adding three bolts to tighten the support rod 51 accordingly. However, this method requires multiple turns of the bolts during adjustment, which is time-consuming and labor-intensive, and is an inferior design compared to the solution of the present application.

[0039] In order to increase the portability of the bracket and the retractability of the support rod 51, an elastic member 54 is connected between the fixing tube 53 and each support rod 51 in the present application, and the elastic member 54 can be a spring; when the elastic member 54 is a spring, a hook 532 is provided on the side wall of the fixing tube 53 below the hinged end of the support rod 51, and a hook 512 is provided on the side wall of the support rod 51 facing the fixing tube 53, and the two ends of the spring are respectively hooked on the hook 532 and the hook 512; when the support rod 51 is retracted, the spring is in a stretched state.

[0040] The implementation principle of this embodiment is as follows: when using the reflector bracket, first install the reflector on the bracket, then move the bracket to the lighting location, and control the lighting angle and lighting position by adjusting the first tightening component 4; if the ground wiring is complicated or there are sundries that are difficult to move, or the ground is uneven, loosen the locking bolt 521, rotate the turntable 61, rotate the arc-shaped clamping rod 611 out of the arc-shaped clamping groove 511 and the clamping hole 533, and then adjust the opening and closing degree of the support rod 51 to adapt to different ground conditions; after the opening and closing degree of the support rod 51 is adjusted, tighten the locking bolt 521 through the lever 522 to complete the installation and fixation of the bracket.

[0041] The present application realizes controllable opening and closing degree of the support rod 51 through the cooperation of the adjustment mechanism 6 and the hinge seat 531, etc., thereby increasing the environmental adaptability of the bracket, being suitable for a variety of complex lighting environments, having low requirements for ground lines, etc., having strong adjustability and strong lighting stability.

[0042] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
