[0003] In actual applications, the existing security monitoring equipment has a prominent problem of limited monitoring range. Due to the constraints of design and installation location, traditional security monitoring equipment can only cover a limited area. In large venues or complex environments, multiple devices need to be installed to achieve comprehensive monitoring, which not only increases costs, but also easily creates monitoring blind spots, posing hidden dangers to security precautions. For this reason, another security monitoring equipment is provided to solve the above technical problems. Utility Model Content

By deploying multiple monitors to cover large venues from multiple directions, the number of monitoring devices required is effectively reduced, thereby significantly reducing the overall cost of the monitoring system and effectively solving the high cost problem currently prevalent in large venue monitoring. The specific technical solution is as follows:

[0005] A security monitoring device includes a support column with a mounting base at the bottom, a carrier with a mounting groove at the top fixedly mounted on the top of the support column, a carrier plate rotatably mounted inside the carrier, two monitor bodies symmetrically mounted on the carrier plate for facilitating adjustment of the monitoring angle, the monitoring directions of the two monitor bodies being set in opposite directions, and a direction adjustment device for driving the carrier plate to rotate being installed inside the carrier.

The adjustment motor is fixedly mounted in the mounting groove, and the output end of the adjustment motor is sleeved with a gear, and the gear is meshed with the inner gear ring.

[0007] In the above technical solution, two adapters are symmetrically fixedly installed on the upper surface of the carrier plate, and the two adapters are rotatably connected to the corresponding monitor bodies respectively, and the lower surface of the monitor body is fixedly installed with an adapter;

[0008] An inverted U-shaped frame is fixed on the upper surface of the carrier plate, a cross slider is vertically slidably installed in the inverted U-shaped frame, and hinge rods are rotatably installed between the left and right ends of the cross slider and the corresponding adapters;

[0009] In the above technical solution, a driving device is installed between the cross slider and the inverted U-shaped frame, and the driving device includes a lifting motor and a screw. The screw is rotatably installed between the carrier plate and the inverted U-shaped frame, and the screw is threadedly connected to the cross slider. The lifting motor is hoisted on the lower surface of the carrier plate, and the output end of the lifting motor is fixedly connected to the lower surface of the screw.

[0010] In the above technical solution, a plurality of heat dissipation openings are provided through the installation groove.

[0011] Compared with the prior art, the security monitoring device of the present invention has the following beneficial effects:

[0012] 1. The present invention can drive the carrier plate and the two monitor bodies above it to rotate flexibly through the direction adjustment device, thereby realizing dynamic adjustment of the monitoring area and significantly expanding the monitoring range. It can also deploy multiple monitors to cover large venues from multiple directions, effectively reducing the number of monitoring devices required, thereby significantly reducing the overall cost of the monitoring system.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In this embodiment, front, back, left, right, up and down are represented by Figure 1 Describes the datum. Figure 1-Figure 2 , the utility model provides a technical solution:

[0019] A security monitoring device includes a support column 1 with a mounting base at the bottom, a carrier 2 with a mounting slot 21 at the top fixedly mounted on the top of the support column 1, a carrier plate 3 rotatably mounted within the carrier plate 2, two monitor bodies 4 symmetrically mounted on the carrier plate 3 for facilitating adjustment of monitoring angles, the two monitor bodies 4 being arranged in opposite directions of each other, and a direction adjustment device 7 for driving the carrier plate 3 to rotate mounted within the carrier plate 2;

[0020] It should be noted that the direction adjustment device 7 includes an inner ring gear 71 and an adjustment motor 72. The inner ring gear 71 is fixedly mounted on the lower surface of the carrier plate 3, and the center of the inner ring gear 71 is on the same vertical line as the center of the carrier plate 3. The adjustment motor 72 is fixedly mounted in the mounting groove 21, and the output end of the adjustment motor 72 is sleeved with a gear 73, which is meshed with the inner ring gear 71.

[0021] When in use, the monitoring device is installed at the center of the desired monitoring site via the support column 1. Subsequently, the adjustment motor 72 is electrically connected to the external remote programming controller. The external remote programming controller can be pre-programmed to control the adjustment motor 72 to slowly rotate 180 degrees forward and backward at a certain frequency to achieve cyclic monitoring of the field of view of different areas. The connection and control method between the adjustment motor 72 and the external remote programming controller are common knowledge in the field and will not be described here. Compared with deploying multiple monitors to cover a large area from multiple directions, this design effectively reduces the number of monitoring devices required and significantly reduces the overall cost of the monitoring system.

[0022] like Figure 2As shown, two adapter seats 31 are symmetrically fixedly installed on the upper surface of the carrier plate 3, and the two adapter seats 31 are rotatably connected to the corresponding monitor bodies 4 respectively. Adapters 41 are fixedly installed on the lower surfaces of the monitor bodies 4. An inverted U-shaped frame 5 is fixed on the upper surface of the carrier plate 3, and a cross slider 51 is vertically slidably installed in the inverted U-shaped frame 5. Articulated rods 52 are rotatably installed between the left and right ends of the cross slider 51 and the corresponding adapters 41 respectively. By sliding the cross slider 51 up and down, the articulated rod 52 can be pulled, thereby flipping the two monitor bodies 4 to adjust the monitoring angle.

[0023] Specifically, if Figure 2 As shown, a driving device 6 is installed between the cross slider 51 and the inverted U-shaped frame 5. The driving device 6 includes a lifting motor 61 and a screw 62. The screw 62 is rotatably installed between the carrier plate 3 and the inverted U-shaped frame 5, and the screw 62 is threadedly connected to the cross slider 51. The lifting motor 61 is hoisted on the lower surface of the carrier plate 3, and the output end of the lifting motor 61 is fixedly connected to the lower surface of the screw 62. The lifting motor 61 is a forward and reverse motor. The lifting motor 61 can drive the screw 62 to rotate, so that the screw 62 is used to drive the cross slider 51 to slide upward or downward, so as to accurately control the sliding of the cross slider 51, thereby realizing accurate adjustment of the monitoring angle of the monitor body 4.

[0024] Finally, in order to facilitate heat dissipation of the lifting motor 61 and the regulating motor 72, as shown in FIG. Figure 1 or Figure 2 As shown, a plurality of heat dissipation openings 211 are provided through the installation slot 21 , and external air flow can flow between the relatively arranged heat dissipation openings 211 , thereby driving the heat in the installation slot 21 and realizing heat dissipation of the lifting motor 61 and the adjustment motor 72 .
