Description

Technical Field

[0001] The utility model relates to the technical field of camera mounting racks, in particular to a lifting camera mounting rack. Background Art

[0002] There are many types of cameras, but the basic principle of cameras is the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected from the object is collected by the camera lens and focused on the light-receiving surface of the camera device. The camera device then converts the light into electrical energy, which is a "video signal". When doing video work, a camera mounting bracket is often used to support the camera to ensure the clarity of the picture during the shooting process.

[0003] According to the Chinese patent with announcement number: CN206018180U, an electric liftable shooting device includes a camera, a bamboo lift rod cloud disk, a bamboo-style lift rod, a base control system box, a chain and a gear. A camera motor is provided at the bottom of the camera, and the camera motor is fixed on the camera chassis through a camera support, and the camera chassis is fixed on the bamboo lift rod cloud disk; a cloud disk support frame is provided at the bottom center of the bamboo lift rod cloud disk, and the cloud disk support frame is connected to the bamboo-style lift rod, which is vertically arranged and one end of which is inserted into the base control system box; a chain, a chain box, a motor controller box and a motor box are provided in the base control system box.

[0004] In the above scheme, a bamboo-joint lifting rod is used to push the camera up and down, which still has the following disadvantages: when the bamboo-joint lifting rod is used to push the camera up and down, it can only rise or fall a fixed distance each time with multiple sections of bamboo, and the height adjustment of the camera is not flexible enough, which reduces the precision of the up and down height adjustment of the camera. Utility Model Content

[0005] The utility model aims to provide a lifting camera mounting frame to solve the problem that the camera can only be raised or lowered by a fixed distance each time with multiple bamboo sections, the lifting and lowering height adjustment of the camera is not flexible enough, and the precision of adjusting the height of the camera up and down is reduced.

[0006] In order to achieve the above-mentioned utility model objectives, the utility model adopts the following technical solutions: a lifting camera mounting bracket, comprising a supporting plate, a sliding groove is provided on the top surface of the supporting plate, a lifting folding plate is slidably inserted inside the sliding groove, a mounting plate is provided on one side of the lifting folding plate, a camera body is detachably provided on the top surface of the mounting plate, a threaded rod is rotatably provided inside the sliding groove, a driven gear is fixed on the threaded rod, a positioning port is provided on one side of the lifting folding plate, a threaded hole is provided on the inner bottom surface of the positioning port, the threaded rod is threadedly connected to the threaded hole, a through hole is provided on one side of the supporting plate, a rotating column is rotatably inserted inside the through hole, a driving gear is fixed to one end of the rotating column, the driving gear and the driven gear are meshed with each other, and a turntable is fixed to the other end of the rotating column.

[0007] Preferably, a positioning column is fixed on one side of the mounting plate, a rotation groove is opened on one side of the lifting folding plate, a bearing is fixed inside the rotation groove, and the surface of the positioning column is fixed to the inner wall surface of the inner ring of the bearing.

[0008] Preferably, connecting plates are fixed on both sides of the lifting folding plate and the mounting plate, a limiting hole is provided on one side of the connecting plate, and a limiting pin is slidably inserted inside the limiting hole.

[0009] Preferably, a positioning plate is detachably provided on the top surface of the mounting plate, and the positioning plate is fixed to the bottom surface of the camera body. A plurality of fixing holes are provided on the top surface of the positioning plate, and a plurality of fixing grooves are provided on the top surface of the mounting plate. Fixing bolts are rotatably provided inside the fixing holes, and the fixing bolts are threadedly connected to the fixing grooves.

[0010] Preferably, two cranks are fixed on one side of the turntable, a rotating sleeve is rotatably sleeved on the cranks, and a blocking block is fixed at one end of the cranks.

[0011] Preferably, a bottom plate is fixed to the bottom surface of the support plate, and two mounting holes are provided on the top surface of the bottom plate, and mounting bolts are rotatably inserted inside the mounting holes.

[0012] Compared with the prior art, a lifting camera mounting bracket adopting the above technical solution has the following beneficial effects:

[0013] First, the staff can rotate the turntable, which will drive the rotating column and the driving gear to rotate synchronously. The meshing of the driving gear and the driven gear will drive the driven gear and the threaded rod to rotate. The rotating threaded rod will use the threaded connection with the threaded hole to push the lifting folding plate to slide up and down inside the sliding groove, so as to adjust the height of the camera body. The staff can control the number of rotations of the driving gear, the driven gear and the threaded rod by controlling the number of rotations of the turntable. The controllability of the number of rotations of the threaded rod increases the precision of the up and down height adjustment of the camera body.

[0014] 2. According to the needs of the environment, the staff can choose different installation methods and types of camera bodies. When it is necessary to install an inverted camera body, the staff will first pull out the limit pin from the inside of the limit hole, then rotate the mounting plate with the positioning column as the center of the circle, and then re-insert the limit pin into the inside of the limit hole after rotating a certain degree to prevent the mounting plate from continuing to rotate, and make the opening of the fixing groove face downward, so that the inverted camera body can be installed on the mounting plate, which increases the application range of the mounting bracket;

[0015] 3. When the staff turns the turntable, they will put their hands on the crank handle and fit them with the rotating sleeve on the crank handle. By applying force to the rotating sleeve, the turntable rotates with the rotating column as the center, which increases the convenience of the staff when turning the turntable.
