Description

Technical Field

[0001] This utility model belongs to the field of monitoring pan-tilt technology and relates to a multi-directional adjustable security monitoring pan-tilt device. Background Technology

[0002] The main drawbacks of existing security monitoring pan-tilt units (PTZs) lie in their inability to perform multi-directional adjustments and their limited monitoring range, primarily in their flexibility and coverage. PTGs that cannot perform multi-directional adjustments typically only rotate horizontally within a single plane, limiting their monitoring angle and range. This results in incomplete coverage of the monitored area, especially in environments with height differences or complex terrain, where blind spots significantly increase. These shortcomings stem from the mechanical limitations of the PTG design and the limitations of the control system. They may lack sufficient drivers or sensors to achieve multi-dimensional motion adjustments. Conventional solutions include adding multiple fixed-angle monitoring cameras to compensate for the limitations of a single PTG, or using PTGs with more advanced adjustment capabilities, such as ball head units with vertical motion capabilities. The drawback of these methods is increased cost due to the need for more hardware and installation. Therefore, there is an urgent need for a multi-directional adjustable security monitoring PTG device to address these issues. Utility Model Content

[0004] This utility model is achieved through the following technical solution: a multi-directional adjustable security monitoring PTZ device, including: an outer connecting shell, a monitoring camera and a guide rail, wherein a set of monitoring cameras for security monitoring is provided inside the outer connecting shell, and a set of mounting cavities is provided inside the outer connecting shell, wherein the front cross-section of the mounting cavity is a rectangular structure.

[0005] The outer connecting shell consists of two sets of rectangular support plates. When the monitoring camera is located inside the mounting cavity, the two sets of outer connecting shells are connected and fixed by long bolts and locking nuts inside the four sets of external corners. The right side of the outer connecting shell is provided with a set of side tensioning brackets for adjusting the distance between the two sets of outer connecting shells. The right side cross-section of the side tensioning bracket is a circular structure, and its upper end is limited and locked by locking nuts and bolts.

[0006] In a preferred embodiment, the right side of the side tensioning bracket is provided with a set of side adjustment motors for adjusting the horizontal rotation angle of the monitoring camera, and the right side of the side adjustment motors is provided with a set of side support arms for connecting, fixing and adjusting the angle of the camera.

[0007] In a preferred embodiment, the side support arm has an L-shaped cross-section when viewed from above. The side support arm is made of aluminum alloy and is connected and fixed to the side adjustment motor. In actual use, the monitoring camera is first installed in the rectangular mounting cavity inside the outer connecting shell. The two sets of outer connecting shells are fixed by four sets of external corner bolts and locking nuts to ensure structural stability. The side tensioning bracket adjusts the distance between the outer connecting shells by tightening nuts and bolts. Its circular structure design facilitates fine adjustment. The side adjustment motor drives the monitoring camera to rotate horizontally. The L-shaped aluminum alloy side support arm provides stable support and assists in angle adjustment. The rear adjustment motor works with the rear support frame to achieve vertical rotation. The rear moving seat slides along the guide rail to expand the monitoring range. The side limit fixing frame and the inner fixing seat jointly constrain the movement trajectory to prevent excessive deviation. In actual use, multi-angle coverage in the horizontal and vertical directions is achieved through motor linkage control. At the same time, the aluminum alloy material ensures lightweight and durability, thereby meeting the security monitoring needs of different scenarios.

[0008] In a preferred embodiment, the left side of the side adjustment motor is the drive end, and its left drive end is internally connected and fixed to the middle position of the right side of the side tensioning bracket.

The side support arm is a movable structure, and a set of rear support frames for supporting and fixing the rear adjustment motor is provided on the rear side.

[0010] In a preferred embodiment, a set of side limiting fixing brackets for connecting and fixing the rear support frame is provided on the left and right sides respectively. There are two sets of side limiting fixing brackets, and both sets of side limiting fixing brackets are connected and fixed to the side limiting fixing brackets by bolts and nuts.

[0012] In a preferred embodiment, the movable base and the two sets of inner fixed bases are integrated into one structure. The movable base has two rows of movable wheels inside, and each row of movable wheels has a set of guide rails on its inner side for guiding its movement. The shape of the guide rails is determined according to the specific monitoring range path. The inner fixed bases ensure a rigid connection between the side limiting fixing frame and the movable base. When the movable base slides along the guide rails of the preset shape, the built-in two rows of movable wheels can realize the smooth displacement of the monitoring camera. The guide rail path needs to be customized according to the actual monitoring range to suit different monitoring ranges.

[0013] The beneficial effects of this utility model after adopting the above technical solution are as follows: the two sets of outer connecting shells are fixed by four sets of external corner bolts and locking nuts to ensure structural stability.
