Description

Technical Field

[0001] This utility model relates to the field of security alarm device technology, and in particular to a modular security alarm device. Background Technology

[0002] A security alarm is a device used for security and prevention. It can issue an alarm signal when it detects abnormal situations to alert people to potential security threats. In some courtyards and orchards, security alarms and their detectors are usually installed as security alarm devices. The detectors of this type of security alarm use thermal infrared (human body) motion detection technology. The detectors will capture changes in the infrared heat source signal emitted by the human body, thereby determining that someone has broken in and triggering a security alarm.

[0003] Existing security alarm devices typically use universal joint brackets to install security detectors on walls in courtyards and orchards. However, these universal joint brackets are relatively simple, and their wind resistance stability after installation is limited. As a result, the detection position of the security detector is easily affected by wind. Therefore, we propose a modular security alarm device. Utility Model Content

[0004] The main objective of this invention is to provide a modular security alarm device. A secondary support mechanism is installed at the security detector with a universal joint bracket. The universal joint bracket and the secondary support mechanism combine to form a modular double-bracket structure. The universal joint bracket is used for the initial installation and angle adjustment of the security detector, while the secondary support mechanism provides additional support below the detector. Through the cooperation of components such as angle plates, steering balls, and ball seats, the secondary support mechanism can be flexibly adjusted according to the detector angle. The connecting plate is secured to the wall with rubber gaskets and locked with expansion bolts. The bottom support plates are connected by wire wrapped around a wire rod, effectively improving the wind resistance and operational stability of the security detector, ensuring that the detector stably maintains its detection angle, and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A modular security alarm device includes a security detector and a universal joint bracket. The universal joint bracket is mounted on the back shell of the security detector. It also includes a secondary support mechanism, which comprises an angle plate, a connecting column, a steering ball, a ball seat, a locking bolt, a magnetic block, a bottom support plate, a side connecting plate, a hole connecting plate, and a winding rod. The angle plate is symmetrically mounted on the bottom shell of the security detector, and a steering ball is welded to the lower surface of the angle plate via a connecting column. The steering ball is rotatably locked within the ball seat, and a locking bolt for pressing against the steering ball is screwed onto the side of the ball seat. A magnetic block for magnetically attracting the steering ball is installed at the bottom of the locking bolt. A bottom support plate is welded to the base surface of the ball seat, and a hole connecting plate is welded to the outer end of the bottom support plate away from the ball seat via a side connecting plate. A winding rod is welded to the surface of the bottom support plate, and annular grooves are arranged on the surface of the winding rod.

[0008] By adopting the above technical solution, bolts can be screwed into the mounting holes of the corner plate and the security detector to lock the corner plate and the security detector together.

[0009] Furthermore, a limited ball cavity is formed in the seat of the ball seat, and a steering ball is fitted inside the limited ball cavity;

[0010] By adopting the above technical solution, the ball seat can be used to hold the steering ball for rotation through the ball cavity.

[0011] Furthermore, the side seat surface of the ball seat is provided with a threaded hole that communicates with the ball cavity, and a locking bolt is screwed into the threaded hole of the ball seat;

[0013] Furthermore, the bolt body of the locking bolt is provided with an L-shaped groove for engaging the L-shaped guide bar, and the L-shaped guide bar is integrally formed on the surface of the magnetic block, and the magnetic block is bonded to the bottom of the locking bolt.

[0014] By adopting the above technical solution, the magnetic block can be clamped and positioned in the L-shaped groove of the locking bolt using an L-shaped guide bar, and then the magnetic block can be firmly bonded to the locking bolt.

[0015] Furthermore, a rubber gasket is bonded to the surface of the connecting plate away from the bottom support plate, and the rubber gasket and the surface of the connecting plate are symmetrically perforated.

[0016] By adopting the above technical solution, the hole connecting plate can press the rubber gasket against the wall, and the expansion bolts can pass through the holes in the hole connecting plate and the rubber gasket, thereby locking the hole pressure plate to the wall.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model incorporates a secondary support mechanism at the security detector with a universal joint bracket. The universal joint bracket and the secondary support mechanism combine to form a modular double-bracket structure. The universal joint bracket is used for the initial installation and angle adjustment of the security detector, while the secondary support mechanism provides additional support below the detector. Through the cooperation of components such as angle plates, steering balls, and ball seats, the secondary support mechanism can be flexibly adjusted according to the detector angle. The hole connecting plate welded to the edge connecting plate at the angle plate is attached to the wall with rubber gaskets and locked with expansion bolts.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a modular security alarm device includes a security detector 1 and a universal joint bracket 2. The universal joint bracket 2 is mounted on the back shell of the security detector 1. It also includes a secondary support mechanism 3, which includes an angle plate 4, a connecting column 5, a steering ball 6, a ball seat 7, a locking bolt 9, a magnetic block 10, a bottom support plate 11, a side connecting plate 12, a hole connecting plate 13, and a winding rod 15. The angle plate 4 is symmetrically mounted on the bottom shell of the security detector 1, and the lower surface of the angle plate 4 is welded and fixed to the bottom shell via the connecting column 5. A steering ball 6 is rotatably locked inside a ball seat 7, and a locking bolt 9 for pressing against the steering ball 6 is screwed onto the side seat of the ball seat 7. A magnetic block 10 for magnetically attracting the steering ball 6 is installed at the bottom of the locking bolt 9. A bottom support plate 11 is welded to the base surface of the ball seat 7, and a hole connecting plate 13 is welded to the outer end of the bottom support plate 11 away from the ball seat 7 through a side connecting plate 12. A winding rod 15 is welded to the surface of the bottom support plate 11, and annular grooves are arranged on the surface of the winding rod 15.

[0027] The angle plate 4 and the bottom shell surface of the security detector 1 are provided with mounting holes, and bolts are screwed between the angle plate 4 and the mounting holes of the security detector 1.

[0028] By adopting the above technical solution, bolts can be screwed into the mounting holes of the angle plate 4 and the security detector 1 to lock the angle plate 4 and the security detector 1 together.

[0029] The ball seat 7 has a limited ball cavity 8 inside its seat, and a steering ball 6 is fitted inside the limited ball cavity 8.

[0030] By adopting the above technical solution, the ball seat 7 can be fitted with the steering ball 6 through the ball cavity 8 for rotation.

[0031] The ball seat 7 has a threaded hole on its side surface that communicates with the ball cavity 8, and a locking bolt 9 is screwed into the threaded hole of the ball seat 7.

[0032] By adopting the above technical solution, the bolt body of the locking bolt 9 can be screwed into the ball-limiting cavity 8 along the threaded hole of the ball seat 7 with the magnetic block 10 to press against the steering ball 6.

[0033] The locking bolt 9 has an L-shaped groove for mounting an L-shaped guide bar at its body, and the L-shaped guide bar is integrally formed on the surface of the magnetic block 10. The magnetic block 10 is bonded to the bottom of the locking bolt 9.

[0034] By adopting the above technical solution, after the magnetic block 10 is clamped and positioned in the L-shaped groove of the locking bolt 9 with the L-shaped guide rib, the magnetic block 10 can be firmly bonded to the locking bolt 9.

[0035] Among them, a rubber gasket 14 is bonded to the surface of the hole connecting plate 13 away from the bottom support plate 11, and the rubber gasket 14 and the surface of the hole connecting plate 13 are symmetrically provided with perforations.

[0036] By adopting the above technical solution, the hole connecting plate 13 can press the rubber gasket 14 to contact the wall, and the expansion bolts can pass through the holes of the hole connecting plate 13 and the rubber gasket 14, thereby locking the hole pressure plate 13 to the wall.

[0037] It should be noted that this utility model is a modular security alarm device. A secondary support mechanism 3 is set at the security detector 1 where the universal joint bracket 2 is installed. After the universal joint bracket 2 is locked to the wall with expansion bolts, the angle plate 4 can be symmetrically locked below the security detector 1 with bolts. Then, the security detector 1 can adjust its detection angle at the universal joint bracket 2 by rotating the ball. Next, the steering ball 6 connected to the angle plate 4 by the connecting column 5 works in conjunction with the bottom support plate 11 of the welded ball seat 7, allowing the bottom support plate 11 to adjust its angle below the steering ball 6 via the ball seat 7. This causes the connecting plate 13 of the outer side connecting plate 12 of the bottom support plate 11 to press against the rubber gasket 14 against the wall. Then, the locking bolt 9 can be screwed into the ball seat 7, where the magnetic block 10 magnetically attracts and presses against the rotation. Angle restrictions are applied to ball 6, and expansion bolts can pass through the holes in hole connecting plate 13 and rubber gasket 14 to lock hole pressure plate 13 to the wall. Then, wire winding rods 15 are located on the two sets of plates of bottom support plate 11 to wind iron wire, thereby binding the two sets of bottom support plates 11 together to form a modular bracket. With the additional support of secondary support mechanism 3, the wind resistance and stability of security detector 1 can be effectively guaranteed, ensuring that security detector 1 can stably maintain its angle for security alarm use. At ball seat 7, there is a locking bolt 9 that works with magnetic block 10 to press against the turning ball 6. By magnetically attracting the turning ball 6, the positioning reliability of the angle of security detector 1 is further enhanced when pressing against the turning ball 6, preventing the angle of security detector 1 from shifting due to vibration and other factors during use.
