Description

Technical Field

[0001] This utility model belongs to the field of engineering testing, and specifically relates to a multi-angle rotating bracket for engineering testing. Background Technology

[0002] Bridges, generally speaking, refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Currently, filming bridges requires considerable time and multiple shooting angles; however, existing filming equipment is relatively simple and cannot adequately meet these requirements. Therefore, tripods are often needed to support the filming equipment for easier shooting.

[0003] For existing supports used to support shooting devices, such as the multi-angle rotating adjustable support disclosed in CN220320942U, the upper end of its fixing frame abuts against the edge of the support plate to achieve positioning of the support plate. However, the manual rotation of the support plate during adjustment is not precise enough and is inconvenient. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a multi-angle rotating bracket for engineering testing, so as to solve the problems in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A multi-angle rotating bracket for engineering testing includes a support assembly and a rotating assembly. The rotating assembly is disposed above the support assembly. The support assembly includes a support frame distributed in a triangular shape. The top of the support frame is hinged to the base, and the middle of the support frame is fixedly connected to a connecting rod. A movable support is movably sleeved on the support frame. The rotating assembly includes a chassis. A power supply is disposed inside the chassis. A first adjusting gear is rotatably disposed on the upper end of the chassis. The first adjusting gear meshes with a second adjusting gear. The second adjusting gear is connected to the drive end of a motor.

[0007] Furthermore, the chassis is fixedly connected to the base, and an annular groove is provided on the upper end of the chassis. Multiple spherical grooves are provided on the lower end of the first adjusting gear, and ball bearings are rolled in the spherical grooves.

[0008] Furthermore, the radius of the spherical groove is matched with the radius of the annular groove.

[0009] Furthermore, the inner wall of the movable support is fixedly provided with elastic elements, and multiple openings are provided through the middle of the support frame in the vertical direction.

[0010] Furthermore, a protruding connecting end is fixedly provided at the lower end of the base, and the end of the connecting end is hinged to the top of the support frame.

[0011] Furthermore, the connecting rod includes a first member and a second member, the first member and the second member are movably connected, and the first member and the second member are respectively fixedly connected to adjacent support frames.

[0012] Furthermore, the top of the first adjusting gear is fixedly connected to the fixed frame, and a fixing pin is provided in the middle of the fixed frame.

[0013] Furthermore, a charging port is provided on the outer side of the chassis.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. The first adjusting gear is precisely rotated by the motor-driven second adjusting gear, and the first and second adjusting gears reduce speed, ensuring the accuracy of the rotation angle and the convenience of operation.

[0016] 2. By using an elastic element to press at the fixed opening position, the movable support can extend and retract within the support frame, improving the convenience of adjusting the extension and retraction of the movable support;

[0017] 3. The connecting rods connect the two support frames, preventing the platform from becoming unbalanced due to excessive outward flare of the support frames under hinged action, thus improving the safety and stability of the support structure. Attached Figure Description

[0030] Example 1:

[0031] like Figure 1As shown, this utility model, specifically, is a multi-angle rotating bracket for engineering testing, comprising a support assembly and a rotating assembly, characterized in that: the rotating assembly is disposed above the support assembly;

[0032] The support assembly includes a support frame 1 arranged in a triangular shape. The top of the support frame 1 is hinged to the base 2, and the middle part of the support frame 1 is fixedly connected to the connecting rod 3. The support frame is movably fitted with a movable support 4.

[0033] The rotating assembly includes a chassis 5, a power supply 6 is installed inside the chassis 5, a first adjusting gear 7 is rotatably installed on the upper end of the chassis 5, the first adjusting gear 7 meshes with a second adjusting gear 8, the second adjusting gear 8 is driven by a motor 9, and the chassis 5 is fixedly connected to the base 2.

[0034] The top end of the first adjusting gear 7 is fixedly connected to the fixed frame 17, and a fixing pin 18 is provided in the middle of the fixed frame 17.

[0035] A charging port 16 is provided on the outer side of the chassis 5.

[0036] like Figure 2-3 As shown, the upper end of the chassis 5 is provided with an annular groove 10, and the lower end of the first adjusting gear 7 is provided with a plurality of spherical grooves 11, and the spherical grooves 11 are provided with rolling balls 12.

[0037] The radius of the spherical groove 11 matches the radius of the annular groove 10, so that all the balls can be placed in the annular groove.

[0038] Using the above structure, during implementation, the shooting device is first fixed by the fixing pin 18 in the fixing bracket 17, and then the second adjusting gear 8 is rotated by turning on the motor 9, which meshes with the first adjusting gear 7 to rotate. When the desired angle is reached, the motor 9 is turned off to fix the shooting device.

[0039] like Figure 4 As shown, an elastic element 13 is fixedly installed on the inner wall of the movable support 4, and multiple openings 14 are provided through the middle of the support frame 1 in the vertical direction.

[0040] like Figure 5 As shown, a protruding connecting end 15 is fixedly provided at the lower end of the base 2, and the end of the connecting end 15 is hinged to the top of the support frame 1.

[0041] like Figure 6 As shown, the connecting rod 3 includes a first rod 301 and a second rod 302. The first rod 301 and the second rod 302 are movably connected, and the first rod 301 and the second rod 302 are respectively fixedly connected to the adjacent support frame 1.

[0042] With the above structure, during implementation, before fixing the shooting equipment, the extension length of the movable support 4 can be adjusted by pressing the elastic element 13, or the outward angle of different support frames 1 can be adjusted by the hinge structure to adapt to different types of terrain conditions. At the same time, the stability of the support is ensured by the limiting effect of the connecting rod 3.

[0043] This application discloses the operating principle of a multi-angle rotating bracket for engineering testing. During implementation, the support components are first adjusted according to different fixed terrains. The extension length of the movable support 4 is adjusted when the elastic element 13 is pressed. When the length is determined, the elastic element 13 is released to allow it to spring back and pop out of the opening 14. The outward angle of the support frame 1 is adjusted by the hinge structure to adapt to the undulations and horizontal differences of the shooting location. At the same time, the limiting effect of the connecting rod 3 also ensures the stability and safety of the bracket.

[0044] After confirming the stability of the support components, the shooting device is fixed to the first adjusting gear 7 by the fixing pin 18 in the fixing bracket 17. Then, the motor 9 is turned on, and the second adjusting gear 8 is rotated by the motor 9. The second adjusting gear 8 meshes with the first adjusting gear 7 to rotate. When the first adjusting gear 7 is observed to have rotated to the required angle, the motor 9 is turned off to stop the rotation, thereby fixing the shooting device.
