[0002] Campus surveillance systems need to adapt to complex environments (such as playgrounds, corridors, outdoor squares, etc.). Existing surveillance brackets often have the following problems: traditional brackets rely on bolts for direct fixation, which makes it difficult to adapt to different substrates such as walls and columns, and they are prone to displacement due to vibration; at the same time, adjusting the monitoring angle relies on overall disassembly and reassembly, which cannot quickly respond to changes in monitoring needs. Therefore, there is an urgent need for a campus-specific surveillance bracket that combines stability, flexible adjustment, and functional expansion. Utility Model Content

Through its modular structural design, it enables rapid installation, multi-dimensional precision adjustment, and peripheral expansion capabilities, adapting to the needs of complex campus scenarios.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A campus-specific four-axis monitoring frame includes a mounting bracket and a calibration adjustment column, wherein the mounting bracket and the calibration adjustment column are connected in cooperation. The characteristic feature is that a pin is provided at the lower position of the calibration adjustment column, and the lower position of the calibration adjustment column is engaged with an external component through the pin.

[0006] Preferably, the mounting bracket includes an external connecting bracket, a rotating buckle, an external support beam, a fixing buckle, and a mating groove. The external connecting bracket is installed at the leftmost position of the mounting bracket. A rotating buckle is provided above the external connecting bracket. An external support beam is provided at the right end of the rotating buckle. A fixing buckle is provided at the right end of the external support beam. A mating groove is provided on the right side of the fixing buckle.

[0007] Preferably, the correction and adjustment column includes a vertical fixing frame, a matching slider, an extension mounting plate, and a limiting block. The vertical fixing frame is connected to the mounting bracket. The matching slider is provided on the inner side of the vertical fixing frame. The extension mounting plate is engaged on the outer side of the matching slider. The limiting block is provided below the matching slider.

[0008] Preferably, the expansion mounting plate is provided with fixing threaded holes, which are arranged in an array on the outer side of the expansion mounting plate.

[0009] Compared with the prior art, this utility model provides a campus-specific four-axis monitoring frame, which has the following beneficial effects:

[0010] 1. The device is easy to install. During use, the pin and the elastic snap ring work together to complete the locking and fixing of the bracket and the base within 5 seconds.

[0011] 2. The device has multi-dimensional adjustment function, and the outer support beam can be extended, retracted and rotated according to the actual situation.

[0012] 3. The device is highly expandable, with six sets of standardized threaded holes on the expansion mounting plate to support the installation of multiple devices such as pan-tilt units and fill lights. Attached Figure Description

[0019] Example 1:

[0020] Reference Figure 1-3A campus-specific four-axis monitoring frame includes a mounting bracket 1 and a calibration and adjustment column 2. The mounting bracket 1 is rigidly connected to the top flange of the calibration and adjustment column 2 via bolts, forming an integral support frame. The lower end of the calibration and adjustment column 2 is equipped with a pin mounting part. The pin is made of stainless steel, and its axis is orthogonal to the vertical center line of the calibration and adjustment column 2. Elastic retaining springs are provided on both sides of the pin, forming an interference fit with the U-shaped groove of the external component 3 to achieve quick locking. The external component 3 can be a wall-mounted base or a ground-mounted pile, adapting to the installation needs of different campus scenarios.

[0021] Mounting bracket 1 consists of an external connecting bracket 101, a rotating buckle 102, an external support beam 103, a fixing buckle 104, and a mating groove 105. The external connecting bracket 101 is an L-shaped cast aluminum part, fixed to the left side of mounting bracket 1 by four sets of M8 bolts. The rotating buckle 102 is a hinged structure with a damped rotating shaft; its right end is inserted into the sleeve of the external support beam 103 and secured with a set screw. The external support beam 103 is a telescopic aluminum tube with a maximum extension length of 500mm, and a fixing buckle 104 is welded to its right end. The fixing buckle 104 has a wedge-shaped protrusion, forming a one-way sliding lock with the dovetail groove of the mating groove 105 to prevent displacement of the monitoring equipment.

[0022] The adjustment column 2 includes a vertical fixing frame 201, a mating slider 202, an extension mounting plate 203, and a limiting block 204. The vertical fixing frame 201 is a rectangular cross-section steel tube with a linear guide rail on its inner wall, forming a precision sliding pair with the ball bearing guide rail of the mating slider 202. The mating slider 202 is locked in place at preset height holes (50mm spacing) on ​​the vertical fixing frame 201 by hand-tightening bolts. The extension mounting plate 203 is made of 6061 aluminum alloy, with a T-shaped tenon on its back, which inserts into the groove of the mating slider 202 and is secured by a spring pin. The limiting block 204 is made of nylon and is fixed to the bottom of the mating slider 202 with screws to prevent the extension mounting plate 203 from excessively descending.

[0023] The 203 extension mounting plate has six sets of M6 threaded holes arranged in a 3x2 matrix with a hole spacing of 80mm x 60mm. The threaded holes are fitted with copper bushings, accommodating standardized mounting interfaces for peripherals such as ball heads, fill lights, or microphones. The plate edges have grooves for waterproof adhesive strips, which can be embedded with EPDM adhesive strips to enhance outdoor dust resistance.

[0024] Example 2:

[0025] Reference Figure 1-2 Similar to Example 1, but with a further improvement: the outer support beam 103 is replaced with a carbon fiber composite tube, the wall thickness is increased to 3mm, and a rubber buffer pad is added to the inside of the fixing buckle 104. The fixing threaded holes of the extension mounting plate 203 are coated with an anti-loosening thread adhesive pre-coating, which is suitable for high-frequency vibration playground monitoring scenarios.
