Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera fixing frame with a line protection structure. Background Art

[0002] Mobile camera is an important device widely used in intelligent monitoring, industrial automation and security systems. It consists of camera, mobile base, rail system, control system and line system. The mobile camera moves left and right or up and down on the rail according to the instructions of the control system to monitor and shoot different areas. The fixed frame usually only has the function of fixing the camera and the mobile base to ensure that the camera can shoot stably during the movement.

[0003] However, there are some defects in the existing mobile camera mounts on the market. First, due to the length limit of the line, the movement range of the camera is greatly limited. If the wire harness distance is set too long, it is easy to be pulled during movement, causing the wire harness to break or be damaged. In addition, the wire harness is prone to entanglement or knotting during movement, further affecting the normal movement and use of the camera. These problems not only increase the maintenance cost and failure rate of the equipment, but may also cause blind spots in the monitoring area, affecting the overall monitoring effect.

[0004] Existing solutions usually rely on manually adjusting the wiring harness or adding wire storage equipment, but these methods have limited effects and cannot completely solve the problem of line protection.

[0005] Therefore, there is an urgent need for a camera fixing bracket with a line protection structure to solve the above technical defects. Utility Model Content

[0006] The purpose of the utility model is to provide a camera fixing bracket with a line protection structure to solve the problem in the above-mentioned background technology that the wire harness distance is too long and is easily pulled during movement, resulting in the wire harness breaking or damage.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a camera fixing frame with a line protection structure, comprising a track frame and a linear track, a linear track is arranged at the bottom end of the track frame, a movable seat is mounted on the outside of the linear track, a camera is fixedly mounted on the bottom end of the movable seat, a line protection structure is arranged on the right side of the movable seat, the line protection structure comprises a wire box fixed to the side wall of the movable seat, a accommodating cavity is arranged in the wire box, a movable winding spring disk is installed at the center position of the accommodating cavity, wiring is wound on the outside of the winding spring disk, an upper wire groove is opened at the top of the wire box, a lower wire groove is opened at the bottom of the wire box, the wiring extends from the upper wire groove and is fixed to the track frame, and the wiring is fixed on the track frame by a buckle block.

[0008] Preferably, a plurality of groups of card slots are processed on the outer edge of the coil spring disk, a mounting plate is fixedly assembled on one side of the lower wire groove, a screw is arranged on one side of the mounting plate, a servo motor is fixed to the bottom end of the mounting plate, the output shaft of the servo motor is fixedly connected to the screw, a threaded block is sleeved on the outside of the screw, a pressure rod is welded on one side of the threaded block, a card block is welded on the top end of the pressure rod, and the card block matches the size of the card slot.

[0009] Furthermore, a side wall of the mounting plate close to the screw rod is provided with a reserved groove, and the threaded block is embedded in the reserved groove and moves up and down.

[0010] Furthermore, the clamping block and the pressure rod form a "T" structure, and the width of the clamping block is smaller than the thickness of the lower wire groove.

[0011] Furthermore, the clamping slots are provided in eight groups, and the clamping slots are distributed around the outer edge of the coil spring disk.

[0012] Furthermore, brackets are fixed on both sides of the upper wire trough, and rotatable wire posts are installed on the brackets, and two groups of wire posts are symmetrically distributed about the upper wire trough.

[0013] Preferably, the buckle blocks are assembled at equal intervals on the outer wall of the track frame, and the number of the buckle blocks is arranged according to the length of the track frame.

[0014] Furthermore, the wire box shell is formed by merging left and right half shells and fixing them by screws, and the half shell assembled at the movable seat is welded to the movable seat.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the camera fixing frame with the line protection structure can not only well protect the wiring from the influence of movement even if it moves a long distance, prevent pulling and breaking, and realize automatic reeling and unreeling of the wiring in coordination with the movement of the camera, without manual operation, and has a wider range of application scenarios, and realizes the reduction of the moving load of the moving seat;

[0016] (1) By providing a wire box, a coil spring disk, and wiring, when the mobile seat follows the movement instruction of the system to drive the camera to move left and right on the linear track, the wiring will need to be extended or retracted into the wire box accordingly. As the moving distance of the camera increases, the wiring is extended outward by a certain drag force, and the coil spring disk unwinds in the opposite direction of its winding direction under the winding action, and cooperates with the locking mechanism at the bottom of the wire box, so that the wiring exposed from the wire box is always stretched out but not tightened. Even if it moves a long distance, the wiring can be well protected from the impact of movement and prevented from being pulled and broken;

[0017] (2) A servo motor, a screw, a threaded block, a clamping block, a receiving cavity, and a pressure rod are provided at the bottom of the wire box. When the camera suddenly stops moving, the servo motor receives a signal from the system to stop moving, and then drives the screw to rotate. The threaded block sleeved on the outside of the screw moves upward, and the clamping block is pushed from the lower wire groove into the receiving cavity and clamped into a group of clamping slots of the winding spring disk to limit its rotation, thereby limiting the continuous unwinding or rewinding of the wiring, fixing the length of the wiring to adapt to the current position of the camera. When the camera continues to move, the screw is reversed, the pressure rod moves downward, the winding spring disk releases the rotation restriction and rotates back, and the wiring is recovered, thereby realizing automatic unwinding and rewinding of the wiring in coordination with the movement of the camera, without manual operation, and having a wider range of application scenarios;

[0018] (3) By providing a track frame, buckle blocks, and a wire box, the wiring length can be set according to the needs of the track frame, half of which is fixed to the track frame by the buckle blocks, and the other half is stored in the wire box. While maintaining unrestricted movement, the portion of the wiring wound in the wire box can be reduced, thereby reducing the size and weight of the wire box, reducing the moving load of the moving seat, and providing a set of wire posts on both sides of the upper wire slot to reduce damage to the wiring caused by being strangled.
