The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 3 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 This is a side view of the first embodiment of the present invention. Figure 3 This utility model Figure 2 Sectional view along line AA.

[0024] The present invention provides a campus library security device, including a camera 101 and an L-shaped plate 102. The rotating mechanism includes a collar 112, two bolts 113, and a servo motor 114. The above-mentioned solution solves the technical problem that the camera 101 has a limited angle during use, which often requires staff to use auxiliary tools such as screwdrivers for adjustment, causing inconvenience to users.

[0025] According to this specific embodiment, two support blocks 103 are provided below the camera 101, a connecting block 104 is provided on one side of the support block 103, a connecting line 105 is provided on the camera 101, and the connecting line 105 passes through the L-shaped plate 102, a rotating mechanism is provided below the L-shaped plate 102, a turntable 106 is provided at the output end of the rotating mechanism, and the turntable 106 is located above the L-shaped plate 102, a support seat 107 and two connecting seats 108 are provided above the turntable 106, a first rotating shaft 109 is provided on the support seat 107, an electric push rod 110 is rotatably provided between the two connecting seats 108, and the electric push rod A second rotating shaft 111 is provided at the output end of 110, and the two supporting blocks 103 are respectively rotatably connected to the first rotating shaft 109 and are sleeved on both ends of the first rotating shaft 109. The second rotating shaft 111 is rotatably connected to the corresponding connecting block 104 and is located between the two connecting blocks 104. The turntable 106 is rotated by the rotating mechanism, so that the monitoring range of the camera 101 can be increased. The monitoring angle of the camera 101 can be adjusted by the setting of the electric push rod 110, so that the up and down angles and left and right rotations of the camera 101 can be freely adjusted when in use, without the need for manual adjustment by the staff.

[0026] Among them, the ring 112 is welded to the servo motor 114 and is located on the outside of the servo motor 114. The ring 112 is also fixedly connected to the L-shaped plate 102 by the bolt 113 and is located below the L-shaped plate 102. The servo motor 114 is located below the L-shaped plate 102, and the output end of the servo motor 114 passes through the L-shaped plate 102. The servo motor 114 can facilitate precise control of position, speed and acceleration, and convert voltage signals into torque and speed to drive the control object, thereby accurately controlling the rotation angle of the camera 101.

[0027] Secondly, a rotating ring 115 is provided below the turntable 106, and a rotating groove 116 is provided above the L-shaped plate 102, and the rotating ring 115 is located in the rotating groove 116. Through the setting of the rotating ring 115 and the rotating groove 116, the stability of the turntable 106 during rotation can be improved, thereby ensuring the stability of the camera 101 during monitoring.

[0028] When using the present invention, by starting the servo motor 114, the servo motor 114 drives the turntable 106 to rotate, so that the camera 101 rotates under the action of the turntable 106, thereby increasing the monitoring range, and then starting the electric push rod 110, so that the second rotating shaft 111 at the output end of the electric push rod 110 and the connecting block 104 rotate, and then the camera 101 rotates with the support seat 107 under the action of the support block 103, thereby completing the angle adjustment, and no manpower is required to directly operate the camera 101 throughout the process. In this way, the technical problem that the angle of the camera 101 is limited during use, and the staff often needs to use auxiliary tools such as screwdrivers to adjust it, causing inconvenience to the user is solved.

[0029] The second embodiment is:

[0030] Based on the first embodiment, please refer to Figures 4 to 6 ,in Figure 4 This is a three-dimensional diagram of the second embodiment of the present invention. Figure 5 This is a front view of the second embodiment of the present utility model. Figure 6 This utility model Figure 5 Cross-sectional view along line BB.

[0031] The utility model provides a campus library security device, which also includes a fixing mechanism and a protective cover 201 . The fixing mechanism includes an arc block 202 , an arc seat 203 , a handle 207 and a supporting pad 208 .

[0032] For this specific embodiment, the fixing mechanism is arranged on the L-shaped plate 102 and is also located on one side of the turntable 106. The connecting line 105 is located between the fixing mechanisms. The protective cover 201 is fixedly connected to the L-shaped plate 102 and is located below the L-shaped plate 102. The servo motor 114 is also located in the protective cover 201. The protective cover 201 can be used to easily protect the servo motor 114, thereby preventing dust from falling directly onto the servo motor 114.

[0033] Among them, two fixed rods 204 are provided on the arc seat 203, and a spring 205 is sleeved on the fixed rod 204. A handle 206 is provided between the two fixed rods 204. The arc block 202 is slidingly connected to the corresponding fixed rod 204 and is located between the two fixed rods 204, and the spring 205 is supported between the handle 206 and the arc block 202. The arc seat 203 is fixedly connected to the L-shaped plate 102 and is located on the L-shaped plate 102, and is also located on one side of the turntable 106.

[0034] Secondly, the handle 207 is fixedly connected to the arc block 202 and is located on the arc block 202. The supporting pad 208 is fixedly connected to the arc block 202 and is located below the supporting pad. By using the thumb to support the grip 206 and then pulling the handle 207 with the remaining four fingers, the handle 207 drives the arc block 202 to move upward. At this time, the connecting line 105 is passed between the arc block 202 and the arc seat 203, and the connecting line 105 is adjusted to a suitable length. Finally, the handle 207 is relaxed, and the arc block 202 moves toward the connecting line 105 under the action of the spring 205, so that the supporting pad 208 supports the connecting line 105, thereby preventing the connecting line 105 from being pulled at will.

[0035] A campus library security device using this embodiment can protect the servo motor 114 through the protective cover 201, thereby preventing dust from falling directly onto the servo motor 114. The thumb is used to press against the grip 206, and the remaining four fingers are used to pull the handle 207, so that the handle 207 drives the arc block 202 to move upward. At this time, the connecting line 105 is passed between the arc block 202 and the arc seat 203, and the connecting line 105 is adjusted to a suitable length. Finally, the handle 207 is relaxed, and the arc block 202 moves toward the connecting line 105 under the action of the spring 205, so that the supporting pad 208 supports the connecting line 105, thereby preventing the connecting line 105 from being pulled at will.

[0036] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
