Description

Technical Field

[0001] This application relates to the field of security monitoring device technology, and in particular to a security monitoring device with an adjustable angle. Background Technology

[0002] Security monitoring refers to a system that uses video acquisition, transmission, storage, and analysis technologies to monitor and protect specific areas or targets in real time. Its core equipment includes cameras, transmission equipment, storage servers, and management platforms, and it is widely used in public safety, traffic management, commercial venues, and smart homes.

[0003] Traditional security monitoring systems typically use pre-installed brackets or welded structures, which cannot dynamically adjust the viewing angle after installation. Some devices fix the relative position of the bracket and the camera with screws. If the monitoring range needs to be adjusted, the entire device must be disassembled and reinstalled, which can easily lead to damage to parts or installation errors. Utility Model Content

[0004] To address the aforementioned problem of inconvenient adjustment of security monitoring devices, this application provides a security monitoring device with an easily adjustable angle.

[0005] The security monitoring device with easily adjustable angle provided in this application adopts the following technical solution:

[0006] An adjustable security monitoring device includes a monitor body. Connecting rods are fixedly connected to both sides of the monitor body. A first movable block is fixedly connected to one side of each connecting rod. A lead screw is threaded into the first movable block. The bottom of the lead screw is fixedly connected to the output end of a motor. The top of the lead screw is fixedly connected to the inner ring of a bearing. A protective frame is fixedly connected to the inner ring of the bearing. The monitor body is located inside the protective frame. A mounting plate is attached to the back of the protective frame. A lug is fixedly connected to the bottom of the back of the mounting plate. The lug is rotatably connected to the telescopic end of an electric push rod via a pin. A base is fixedly connected to the bottom of the electric push rod.

[0007] Preferably, a second movable block is fixedly connected to one end of the monitor body away from the lead screw, and a round rod is slidably connected to the middle of the second movable block, with both ends of the round rod fixedly connected to the protective frame.

[0008] Preferably, a connecting block is fixedly connected to the top of the back of the mounting plate, the connecting block is rotatably connected to one end of the drive rod via a pin, and a base is rotatably connected to the back of the drive rod.

[0009] Preferably, mounting blocks are fixedly connected to both sides of the base, and the surface of the mounting blocks is provided with multiple mounting holes.

[0010] Preferably, multiple fixing blocks are symmetrically fixedly connected to both sides of the mounting plate, and the fixing blocks are detachably connected to the protective frame by bolts.

[0011] Preferably, the mounting hole of the mounting block is a strip hole or a circular hole, and an anti-loosening gasket is provided in the hole.

[0012] Preferably, the protective frame has an overall U-shaped structure with openings on its left and right sides.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The monitor body moves up and down through a combination of motor and lead screw. The electric push rod, in conjunction with the lugs, adjusts the pitch angle. Meanwhile, the U-shaped opening design of the protective frame helps the monitor rotate left and right. The coordinated action of multiple structures allows the monitor to flexibly adjust its height, pitch, and horizontal viewing angle, thereby covering a wider area, meeting the monitoring needs of different scenarios, and improving the flexibility of the monitor.

[0015] 2. The mounting plate and the protective frame are connected by a detachable method using fixing blocks and bolts, which facilitates the disassembly and assembly of the protective frame and provides convenience for the maintenance, repair and replacement of the monitor body; the mounting hole design of the base mounting block, together with anti-loosening washers, ensures a stable connection and reduces potential failure risks; effectively reducing the difficulty of operation, improving maintenance efficiency and reducing maintenance costs.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-4 This utility model provides a security monitoring device with an easily adjustable angle, including a monitor body 1. Connecting rods 3 are fixedly connected to both sides of the monitor body 1. A first moving block 301 is fixedly connected to one side of the connecting rod 3. A lead screw 302 is threadedly connected to the inside of the first moving block 301. The bottom of the lead screw 302 is fixedly connected to the output end of the motor 303. The inner ring of the bearing 304 is fixedly connected to the top of the lead screw 302. A protective frame 2 is fixedly connected to the inner ring of the bearing 304. The monitor body 1 is located inside the protective frame 2. A mounting plate 4 is attached to the back of the protective frame 2. A support ear 406 is fixedly connected to the bottom of the back of the mounting plate 4. The support ear 406 is rotatably connected to the telescopic end of the electric push rod 405 through a pin. A base 404 is fixedly connected to the bottom of the electric push rod 405.

[0023] When the height of the monitor body 1 needs to be adjusted, the motor 303 starts, and its output end drives the lead screw 302 to rotate. Since the first moving block 301 is threadedly connected to the lead screw 302, and the first moving block 301 is fixedly connected to the monitor body 1 via the connecting rod 3, while the top of the lead screw 302 is connected to the protective frame 2 via the bearing 304 to reduce friction, the first moving block 301 drives the monitor body 1 to rise or fall along the axis of the lead screw 302 within the protective frame 2, thereby achieving height adjustment of the monitor body 1. The telescopic end of the electric push rod 405 is rotatably connected to the lug 406 on the back of the mounting plate 4 via a pin, and the bottom of the electric push rod 405 is fixed to the base 404. When the angle of the monitor body 1 needs to be adjusted, the electric push rod 405 extends and retracts. The movement of its telescopic end drives the mounting plate 4 to rotate around the connection point with the drive rod 403. The rotation of the mounting plate 4 then drives the protective frame 2 and the monitor body 1 inside to rotate together, thereby achieving angle adjustment of the monitor body 1.

[0024] A bellows is fitted onto the surface of the lead screw 302, and the bottom of the first moving block 301 is sealed to it to form a fully enclosed protective structure. When the first moving block 301 moves up and down along the lead screw 302, the bellows expands and contracts accordingly, always maintaining a state of full coverage of the lead screw 302. The bellows is not shown in the figure.

[0025] The height of the monitor body 1 can be precisely controlled by the motor 303 and the lead screw 302 to meet the needs of different monitoring scenarios. The electric push rod 405 facilitates the adjustment of the angle of the monitor body 1, making the monitoring range wider and improving the flexibility and effectiveness of monitoring. The protective frame 2 provides protection for the monitor body 1, preventing it from being damaged by the external environment.

[0026] In a preferred embodiment, a second movable block 6 is fixedly connected to one end of the monitor body 1 away from the lead screw 302, and a round rod 601 is slidably connected to the middle of the second movable block 6. The two ends of the round rod 601 are fixedly connected to the protective frame 2.

[0027] Since the second movable block 6 is slidably connected to the round rod 601, and both ends of the round rod 601 are fixedly connected to the protective frame 2, the round rod 601 provides guidance for the movement of the second movable block 6. When the monitor body 1 rises or falls, the second movable block 6 slides smoothly along the round rod 601, ensuring that the monitor body 1 remains stable during movement and does not shake or deviate.

[0028] In a preferred embodiment, a connecting block 402 is fixedly connected to the top of the back of the mounting plate 4. The connecting block 402 is rotatably connected to one end of the drive rod 403 via a pin. A base 404 is rotatably connected to the back of the drive rod 403.

[0029] When the electric push rod 405 extends or retracts to adjust the angle of the mounting plate 4, the mounting plate 4 rotates around the connection point with the drive rod 403. One end of the drive rod 403 is rotatably connected to the connecting block 402 on the back of the mounting plate 4 via a pin, and the other end is rotatably connected to the base 404. During the rotation of the mounting plate 4, the drive rod 403 also rotates, playing a role in assisting support and stabilizing the mounting plate 4, enabling the mounting plate 4 to rotate smoothly around the connection point, thereby driving the protective frame 2 and the monitor body 1 to achieve angle adjustment.

[0030] In a preferred embodiment, mounting blocks 5 are fixedly connected to both sides of the base 404, and the surface of the mounting blocks 5 is provided with a plurality of mounting holes 501.

[0031] Mounting holes 501 on mounting block 5 are used to pass mounting bolts through, fixing mounting block 5 to mounting surface, thereby fixing the entire device to mounting surface.

[0032] In a preferred embodiment, multiple fixing blocks 401 are symmetrically fixedly connected to both sides of the mounting plate 4, and the fixing blocks 401 are detachably connected to the protective frame 2 by bolts.

[0033] When it is necessary to maintain or replace the monitor body 1, simply loosen the bolts to separate the protective frame 2 from the mounting plate 4, making it convenient to operate the monitor body 1 inside the protective frame 2; during installation, place the protective frame 2 in a suitable position and tighten the bolts to complete the fixation.

[0034] In a preferred embodiment, the mounting hole 501 of the mounting block 5 is a strip hole or a circular hole, and an anti-loosening gasket is provided inside the hole.

[0035] The design of the strip-shaped or round hole increases the flexibility and adaptability of the 404 stainless steel base installation, meeting the needs of different installation scenarios. Anti-loosening washers effectively prevent bolts from loosening.

[0036] In a preferred embodiment, the protective frame 2 has an overall U-shaped structure with openings on its left and right sides. The U-shaped structure and the left and right openings significantly expand the horizontal viewing angle of the monitor, enabling it to cover a wider area and improve monitoring effectiveness.

[0037] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a security monitoring device with an adjustable angle provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
