Description

Technical Field

[0001] This invention relates to the field of film and television shooting technology, and in particular to a mobile device specifically designed for film and television shooting that is easy to assemble. Background Technology

[0002] Optics is another technique in photographic creation. Optics mainly involves knowledge of photographic lenses and filters. Focal length, focus, aperture, depth of field, and image formation are all elements of optical creation. In film and television photography, it is usually necessary for the camera equipment to follow the movement of the subject and maintain a fixed shooting angle during the movement. Therefore, moving devices to guide the movement of the camera equipment have been developed.

[0003] Currently, mobile devices are typically built by fixing them to the ground using a fixed mounting frame. Assembling and securing the various components takes a considerable amount of time. Once installed, the mobile guiding device is usually fixed and cannot be disassembled at will. When in use, the camera equipment is placed on the mounting frame, which guides the movement of the camera equipment. When filming is completed at the current location and a new location needs to be filmed, the mobile guiding device needs to be disassembled and transported one by one. Furthermore, due to the cumbersome loading and unloading process, it often needs to be set up in advance. If there is not enough time to set up, the filming period needs to be postponed. Summary of the Invention

[0004] To overcome the drawbacks of the cumbersome assembly and disassembly of existing mobile guidance devices, a mobile device for film and television shooting that is easy to assemble is provided.

[0005] The technical solution is as follows: A mobile device for film and television shooting that is easy to assemble includes a guide rod, a connecting plate, a support rod, a mounting plate, a limiting insert frame, a sliding limiting component, and a limiting installation assembly. The guide rod has a groove, and a protrusion is provided on the opposite side of the groove. The two guide rods are connected and fixed by the connecting plate. The support rod is symmetrically and slidably connected to the bottom of the connecting plate. The support rod has a notch. The limiting insert frame is symmetrically and slidably connected to the connecting plate. The limiting insert frame slides into the notch. The mounting plate is slidably placed on the guide rods on both sides using the protrusions. The sliding limiting component is slidably connected to the mounting plate. The sliding limiting component slides into the groove. The limiting installation assembly is provided on the mounting plate for mounting the equipment on it.

[0006] Optionally, the sliding limiting member consists of a connecting rod and rollers rotatably connected to both ends of the connecting rod.

[0007] Optionally, the limiting installation assembly includes an installation cylinder, a pressure rod, a sloping groove plate, a first spring, a push plate, and a second spring. The installation cylinder is fixedly connected to the installation plate, the pressure rod is slidably connected to the installation cylinder, the two ends of the pressure rod are fixedly connected to the sloping groove plate, the connecting rod is slidably connected to the sloping groove plate, the sloping groove plate and the installation plate are jointly fixedly connected to the first spring, the push plate is fixedly connected to the connecting rod, the push plate is in contact with the limiting insert plate frame, and the limiting insert plate frame and the connecting plate are jointly fixedly connected to the second spring.

[0008] Optionally, the connecting rod is n-shaped and passes through the mounting plate, with the roller located below the mounting plate.

[0009] Optionally, it also includes a pulling assembly, which is provided on the connecting plate; the pulling assembly includes a first winding wheel, a pull rope and a push rod, the first winding wheel is rotatably connected to the connecting plate, the pull rope is wound on the first winding wheels located at both ends of the guide rod, and the push rod is fixed to the bottom of the mounting plate, with the push rod passing through the pull rope.

[0010] Optionally, it also includes a drive assembly, which is provided at the bottom of the connecting plate; the drive assembly includes a fixed frame, a motor, a screw and a second winding wheel, the fixed frame is fixedly connected to the bottom of the connecting plate, the motor is slidably connected to the fixed frame, the screw is rotatably connected to the fixed frame, the screw is threadedly connected to the sliding connection part of the motor, the second winding wheel is fixedly connected to the output shaft of the motor, and the pull rope is wound on the second winding wheel.

[0011] Optionally, the bottom end of the screw is provided with a handwheel for easy turning of the screw.

[0012] Optionally, it also includes a hook, with one end of the guide rod fixed to the hook and the other end of the guide rod having a slot that engages with the hook.

[0013] Optionally, it also includes a reinforcement mechanism. The reinforcement mechanism is provided on the mounting cylinder. The reinforcement mechanism includes a guide rod, a buckle and a third spring. At least two guide rods are evenly spaced on the upper side of the mounting cylinder. Buckles are slidably provided on the guide rods. A third spring connects the buckle and the mounting cylinder.

[0014] The beneficial effects are: the present invention uses a limiting insert plate to restrict and fix the support rod, so that the fixation between the support rod and the connecting plate only requires the limiting insert plate to slide and lock the notch on the support rod. When disassembling, when the camera equipment is removed from the mounting cylinder, the limiting insert plate can simultaneously disengage from the notch on the support rod, thus achieving the effect of quick assembly and disassembly.

[0015] The guide rods are joined together using hooks and latches, which allows for rapid extension of the mobile guide device and makes it easier to use. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0030] A mobile device specifically designed for film and television shooting that is easy to assemble, such as... Figures 1-5 As shown, the assembly includes a guide rod 1, a connecting plate 2, a support rod 3, a mounting plate 4, a limiting insert bracket 5, a sliding limiting component 6, and a limiting mounting assembly 7. The guide rod 1 has a groove 1a of the same length as the rod body. On the other side of the guide rod 1 corresponding to the groove 1a, there is also a protrusion 1b of the same length as the rod body. Two guide rods 1 are connected and fixed to multiple connecting plates 2 by bolts to form a frame. The bottom of the connecting plate 2 is symmetrically and longitudinally slidably connected to the support rod 3. The support rod 3 is laterally slidably engaged with the connecting plate 2. The support rod 3 has a notch 3a. The limiting insert bracket 5 is symmetrically and slidably connected to the connecting plate 2. The limiting insert bracket 5 slides into the notch 3a. After the limiting insert bracket 5 is engaged with the notch 3a... This ensures that the support rod 3 will not detach from the connecting plate 2. The mounting plate 4 is slidably placed on the guide rods 1 on both sides using the protrusions 1b. A pair of wheels are symmetrically arranged on the bottom of the mounting plate 4. The wheels slide in contact with the protrusions 1b, that is, pushing the mounting plate 4 allows it to slide on the guide rods 1. The mounting plate 4 is slidably connected to the sliding limit member 6. The sliding limit member 6 slides and fits into the groove 1a to stabilize the mounting plate 4 and prevent it from shifting. The sliding limit member 6 consists of a connecting rod 61 and rollers 62 rotatably connected to both ends of the connecting rod 61. The connecting rod 61 is n-shaped and passes through the mounting plate 4. The rollers 62 are located below the mounting plate 4. The mounting plate 4 is provided with a limiting mounting assembly 7 for mounting the equipment on it.

[0031] like Figure 6As shown, the limiting installation assembly 7 includes an installation cylinder 71, a pressure rod 72, a sloping groove plate 73, a first spring 74, a push plate 75, and a second spring 76. The installation cylinder 71 is fixedly connected to the installation plate 4 by bolts. The pressure rod 72 is longitudinally slidably connected to the installation cylinder 71. When installing the camera equipment, the pressure rod 72 can be pushed downwards. The sloping groove plates 73 are welded to both ends of the pressure rod 72. The connecting rod 61 is slidably connected to the sloping groove plate 73. When the pressure rod 72 pushes the sloping groove plate 73 downwards, the connecting rod 61, along with the roller 62, will be tightly fitted into the groove 1a. The first spring 74 is fixedly connected between the sloping groove plate 73 and the installation plate 4. The first spring 74 is used for... The inclined plate 73 is kept in an upward position. It can only be pressed down when the pressure rod 72 is pushed down. The push plate 75 is fixed to the connecting rod 61. As the connecting rod 61 and the roller 62 are inserted into the groove 1a, the push plate 75 pushes the limiting insert frame 5 into the notch 3a. The limiting insert frame 5 and the connecting plate 2 are fixed together by the second spring 76. When the push plate 75 does not push the limiting insert frame 5, the second spring 76 will push the limiting insert frame 5 out of the notch 3a. That is, the guide frame is stable only when the camera equipment is installed. In other states, it can be disassembled at any time. Example 2

[0032] Based on Example 1, such as Figure 7 and Figure 8 As shown, it also includes a pulling assembly 8, which is installed on the connecting plate 2. The pulling assembly 8 includes a first winding wheel 81, a pull rope 82, and a push rod 83. The first winding wheel 81 is rotatably connected to the connecting plate 2. A pull rope 82 is wound on the first winding wheels 81 at the two ends of the connecting plate 2 located at the front and rear ends of the guide rod 1. The push rod 83 is welded to the bottom of the mounting plate 4 and passes through the pull rope 82. As the pull rope 82 is pulled, the mounting plate 4 connected to the pull rope 82 via the push rod 83 can move accordingly, thereby enabling the camera equipment installed on the mounting plate 4 to move over a long distance.

[0033] like Figure 9As shown, it also includes a drive assembly 9, which is installed at the bottom of the connecting plate 2. The drive assembly 9 includes a fixed frame 91, a motor 92, a screw 93, and a second winding wheel 94. The fixed frame 91 is fixedly connected to the bottom of the connecting plate 2 by bolts. The motor 92 is longitudinally slidably connected to the fixed frame 91, and the screw 93 is rotatably connected to the fixed frame 91. The bottom end of the screw 93 is provided with a handwheel for easy turning. The screw 93 is threadedly connected to the sliding connection part of the motor 92. Rotating the screw 93 allows the height of the motor 92 on the fixed frame 91 to be adjusted. The second winding wheel 94 is fixedly connected to the output shaft of the motor 92. The pull rope 82 is wound around the second winding wheel 94 in a loop. The motor 92 pulls the pull rope 82, thereby moving the mounting plate 4. When the height of the motor 92 is adjusted accordingly, the pull rope 82 can be tightened or loosened to achieve the purpose of disassembly.

[0034] like Figure 10 and Figure 11 As shown, it also includes a hook 101. The hook 101 is welded to the front end face of the guide rod 1, and the rear end face of the guide rod 1 has a slot 102 that fits with the hook 101. When a frame consisting of multiple guide rods 1 and connecting plates 2 needs to be connected, the hook 101 on the next guide rod 1 can be inserted into the slot 102 of the previous guide rod 1 to complete the splicing and assembly.

[0035] like Figure 2 and Figure 12 As shown, it also includes a reinforcement mechanism 11. The mounting cylinder 71 is provided with a reinforcement mechanism 11 for fixing the camera equipment. The reinforcement mechanism 11 includes a guide rod 111, a buckle 112 and a third spring 113. Three guide rods 111 are evenly spaced on the upper side of the mounting cylinder 71. Buckles 112 are slidably mounted on the guide rods 111. The buckles 112 are connected to the mounting cylinder 71 by the third spring 113. During the installation of the camera equipment, there may be instability. During installation, the camera equipment base contacts the inclined surface of the buckle 112, pushing the buckle 112 to open. The third spring 113 is compressed, and the camera equipment base moves downward until it disengages from the buckle 112. Under the action of the third spring 113, the buckle 112 returns to its inward position, fixing the camera equipment base, improving stability and facilitating the installation of the camera equipment.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
