Technical Field

[0001] This utility model relates to the field of concealed monitoring technology, and in particular to a concealed monitoring device for security doors. Background Technology

[0002] A concealed security door camera is a hidden camera installed on a security door. It is usually designed to be difficult to detect and its function is to enhance security and prevent intrusion by monitoring the area around the door in real time.

[0003] Utility model CN221509688U discloses a concealed surveillance camera. Its key technical features include: a chassis mounted on the ground, with a support frame fixedly connected to the chassis via a bracket; a support plate fixedly connected to the top of the support frame, a movable seat movably mounted above the support plate, and a cylindrical speaker movably mounted above the movable seat; a dustproof mesh is provided on the circumference of the cylindrical speaker, and a concealed surveillance head is embedded inside the cylindrical speaker; an adapter frame is fixedly connected to the bottom of the cylindrical speaker. This utility model, by simultaneously coordinating the tilt monitoring adjustment and the circumferential rotation monitoring of the concealed surveillance head, enables a wider monitoring range, avoiding the limitations of existing concealed surveillance cameras where the lens orientation is difficult to adjust after installation, resulting in a smaller monitoring range and greater limitations. This helps ensure a better overall monitoring effect.

[0004] Regarding the above-mentioned content, the following technical defects exist: A concealed surveillance camera for a security door is a monitoring device integrated into the door body or an inconspicuous location on the outer surface. Workers typically use screws to install the power box on the surface of the security door or the wall to which the door is located, connecting the camera to the power port of the power box. However, prolonged contact between the camera and the power port of the power box can cause the power interface to loosen, preventing the camera from functioning properly.

[0005] Therefore, it is necessary to provide a new type of concealed monitoring device for security doors to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art where prolonged contact between the monitor and the power port of the power supply box can cause the power interface between them to become loose, which in turn prevents the monitor from working properly.

[0007] To solve the above-mentioned technical problems, this utility model provides a concealed monitoring device for security doors, including: a power supply box, a monitoring body mounted on the upper surface of the power supply box, an adjustment device provided on the side of the monitoring body near the power supply box, the adjustment device including a fixed frame, one inner wall of the fixed frame being fixedly connected to the power supply box, a baffle being fixedly connected to one side of the fixed frame, a sliding block sliding through the other inner wall of the fixed frame, two springs being fixedly connected to one side of the sliding block, the ends of the two springs away from the sliding block being fixedly connected to the same fixed block, the fixed block being fixedly connected to one end of the power supply box, two connecting blocks being fixedly connected to the side of the sliding block, a bidirectional screw being rotatably connected to one side of one of the connecting blocks, the bidirectional screw rotatably penetrating the inner wall of the other connecting block, both ends of the arc surface of the bidirectional screw being threadedly connected to clamps, a sliding rod being fixedly connected to one side of the clamp, and the two sliding rods slidingly penetrating the two inner walls of the sliding block respectively.

[0008] The aforementioned components achieve the following effect: The concealed monitoring unit for security doors is a monitoring device integrated into the interior or exterior of the door in a location that is not easily noticeable. Its main purpose is to monitor the area around the door without attracting attention. Typically, workers use screws to install the power box on the wall where the security door is located, and then connect the monitoring unit to the power port of the power box. The monitoring unit can then operate. However, prolonged contact between the monitoring unit and the power port of the power box can cause the power interface between the two to loosen. A loose power interface will prevent the monitoring unit from continuing to work normally. In this case, an adjustment device can be used to fix the power interface between the two, thereby improving the stability of the connection between the monitoring unit and the power box and improving the monitoring effect of the monitoring unit.

[0009] Preferably, a limiting rod is slidably connected to the inner wall of the spring, one end of the arc surface of the limiting rod is fixedly connected to the sliding block, and the other end of the arc surface of the limiting rod slides through the inner wall of the fixed block.

[0010] The effect achieved by the above components is that when the spring is in motion, the limiting rod installed inside the spring can limit the movement of the spring, thereby improving the stability of the spring during movement and increasing the service life of the spring.

[0011] Preferably, a contact ring is fitted onto one end of the arc surface of the limiting rod, and the contact ring is circular in shape.

[0012] The effect achieved by the above components is that when the limit rod moves and comes into contact with the fixed block, the contact ring installed on the limit rod can prevent the limit rod from directly contacting the fixed block, and the contact ring can prevent damage from contact between the two.

[0013] Preferably, a plurality of anti-slip grooves are provided at one end of the arc surface of the bidirectional screw, and the plurality of anti-slip grooves are evenly distributed on the arc surface of the bidirectional screw.

[0014] The effect achieved by the above components is that when the clamp is rotated by the bidirectional screw, the anti-slip groove on the bidirectional screw can increase the friction on the surface of the bidirectional screw body, thereby improving the rotation efficiency of the bidirectional screw through the anti-slip groove.

[0015] Preferably, the arc surface of the monitor body is provided with an auxiliary device, the auxiliary device including a fixing ring, the fixing ring being fixedly connected to the monitor body, a connecting rod being fixedly connected to the inner wall of the fixing ring, a rotating rod being rotatably connected to the arc surface of the connecting rod, a protective shell being fixedly connected to one end of the arc surface of the rotating rod, a magnetic block being fixedly connected to one end of the arc surface of the protective shell, a metal ring being fixedly connected to the side of the fixing ring near the magnetic block, all three magnetic blocks being attracted to the metal ring, and coil springs being slidably connected to both ends of the arc surface of the rotating rod, with the two ends of the coil springs being fixedly connected to one side wall of the rotating rod and the fixing ring, respectively.

[0016] The effect achieved by the above-mentioned components is that when the monitor body is not in use, the lens of the monitor body can be protected by the auxiliary device, thereby preventing damage to the lens of the monitor body due to external forces when it is not in use.

[0017] Preferably, an adjusting block is fixedly connected to one end of the arc surface of the protective shell, and an auxiliary groove is provided on one side of the adjusting block.

[0018] The effect achieved by the above components is as follows: when it is necessary to move the angle of the protective shell, the adjusting block installed on the protective shell can be used to move the protective shell. The adjusting block can improve the stability of the movement of the protective shell, and the auxiliary groove opened on the adjusting block can improve the friction of the adjusting block surface, thus making it easier for personnel to use the adjusting block.

[0019] Preferably, the connecting rod is a titanium alloy rod.

[0020] The effect achieved by the above components is that the titanium alloy connecting rod has a relatively hard surface, which makes it less prone to deformation even after long-term use and results in a longer service life.

[0021] Compared with related technologies, the concealed monitoring device for security doors provided by this utility model has the following advantages:

[0022] By setting up an adjustment device, when the monitor is connected to the power supply box, the position of the power interface where the two are in contact can be fixed through the adjustment device. In this way, the stability of the monitor when in contact with the power supply box can be improved, so that the monitor can work stably and improve the working effect.

[0023] By setting up an auxiliary device, the lens of the monitor can be protected when it is not in use. This prevents the lens from being scratched or worn by external objects, thus avoiding any impact on the monitor's normal operation. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5The present invention provides a hidden monitoring device for a security door, comprising: a power supply box 1, a monitoring body 4 mounted on the upper surface of the power supply box 1, an adjustment device 2 provided on the side of the monitoring body 4 near the power supply box 1, and an auxiliary device 3 provided on the arc surface of the monitoring body 4.

[0033] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes a fixed frame 201. One inner wall of the fixed frame 201 is fixedly connected to the power supply box 1. A baffle 205 is fixedly connected to one side of the fixed frame 201. A sliding block 202 slides through the other inner wall of the fixed frame 201. Two springs 203 are fixedly connected to one side of the sliding block 202. The ends of the two springs 203 away from the sliding block 202 are fixedly connected to the same fixed block 204. The fixed block 204 is fixedly connected to one end of the power supply box 1. Two connecting blocks 210 are fixedly connected to the side of the sliding block 202. A bidirectional screw 206 is rotatably connected to one side of one of the connecting blocks 210. The bidirectional screw 206 rotatably passes through the inner wall of the other connecting block 210. The two ends of the arc surface of the bidirectional screw 206 are... The device has a threaded connection with a clamp 207, and a sliding rod 208 is fixedly connected to one side of the clamp 207. The two sliding rods 208 slide through the two inner walls of the sliding block 202 respectively. The concealed monitoring device body 4 for the security door is a monitoring device integrated into the door body or the outer surface of the door in a location that is not easily noticed. Its main purpose is to monitor the area around the door without attracting attention. Usually, workers will use screws to install the power box 1 on the wall where the security door is located, and connect the monitoring device body 4 to the power port of the power box 1. The monitoring device body 4 can then work. However, the monitoring device body 4 is in contact with the power port of the power box 1 for a long time, which may cause the power interface between the two to loosen. This will cause the monitor body 4 to malfunction. In this case, the power interface of both devices can be fixed using the adjustment device 2, thereby improving the stability of the monitor body 4 when connected to the power box 1 and enhancing the monitoring effect of the monitor body 4. A limit rod 209 is slidably connected to the inner wall of the spring 203. One end of the arc surface of the limit rod 209 is fixedly connected to the sliding block 202, and the other end of the arc surface of the limit rod 209 slides through the inner wall of the fixed block 204. When the spring 203 moves, the limit rod 209 installed inside the spring 203 can limit the movement of the spring 203, thereby improving the stability of the spring 203 during movement and extending its service life. One end of the arc surface of the double-acting screw 206 is fitted with a contact ring 212. The contact ring 212 is circular. When the limiting rod 209 moves and comes into contact with the fixed block 204, the contact ring 212 installed on the limiting rod 209 can prevent the limiting rod 209 from directly contacting the fixed block 204. The contact ring 212 can prevent damage from contact between the two. One end of the arc surface of the double-acting screw 206 is provided with several anti-slip grooves 211. The several anti-slip grooves 211 are evenly distributed on the arc surface of the double-acting screw 206. When the clamp 207 is rotated by the double-acting screw 206, the anti-slip grooves 211 on the double-acting screw 206 can increase the friction of the surface of the double-acting screw 206. Thus, the rotation efficiency of the double-acting screw 206 can be improved by the anti-slip grooves 211.

[0034] In the embodiments of this utility model, please refer to Figure 5 The auxiliary device 3 includes a fixing ring 31, which is fixedly connected to the monitor body 4. A connecting rod 32 is fixedly connected to the inner wall of the fixing ring 31. A rotating rod 33 is rotatably connected to the arc surface of the connecting rod 32. A protective shell 34 is fixedly connected to one end of the arc surface of the rotating rod 33. A magnetic block 36 is fixedly connected to one end of the arc surface of the protective shell 34. A metal ring 37 is fixedly connected to the side of the fixing ring 31 near the magnetic block 36. All three magnetic blocks 36 are attracted to the metal ring 37. A coil spring 35 is slidably connected to both ends of the arc surface of the rotating rod 33. The two ends of the coil spring 35 are respectively fixedly connected to one side wall of the rotating rod 33 and the fixing ring 31. When the monitor body 4 is not in use, the lens of the monitor body 4 can be protected by the auxiliary device 3. Thus, the auxiliary device 3 can prevent the monitoring... When the lens of the controller body 4 is not in use, it may be damaged due to external forces. An adjustment block 38 is fixedly connected to one end of the arc surface of the protective shell 34. An auxiliary groove 39 is provided on one side of the adjustment block 38. When it is necessary to move the angle of the protective shell 34, the adjustment block 38 installed on the protective shell 34 can be used to move the protective shell 34. The adjustment block 38 can improve the stability of the movement of the protective shell 34. The auxiliary groove 39 on the adjustment block 38 can improve the friction of the surface of the adjustment block 38, making it easier for personnel to use the adjustment block 38. The connecting rod 32 is a titanium alloy rod. The surface of the titanium alloy connecting rod 32 is relatively hard, which makes it less likely to deform after long-term use and has a better service life.

[0035] The working principle of the concealed monitoring device for security doors provided by this utility model is as follows: Connect the monitoring device body 4 to the power port of the power box 1. At this time, the sliding block 202 can be pulled upward. The movement of the sliding block 202 will drive the spring 203 to stretch. The movement of the sliding block 202 will drive the connecting block 210 to adjust its height. At this time, the bidirectional screw 206 can be rotated inside the connecting block 210. The rotation of the bidirectional screw 206 will drive the two clamps 207 to move. The movement of the two clamps 207 will slide along the sliding rod 208 on the inner wall of the sliding block 202. At this time, the two clamps 207 can move towards each other. The bidirectional screw 206 can drive the clamps 207 to contact the monitoring device body 4, thereby clamping the monitoring device body 4.

[0036] Pulling the protective shell 34 upwards causes the rotating rod 33 to rotate on the connecting rod 32. The rotation of the rotating rod 33 causes the coil spring 35 to deform, attracting the magnetic block 36 installed on the protective shell 34 to the metal ring 37 installed on the fixing ring 31. At this time, the protective shell 34 can be attached to the lens of the monitor body 4 and fixed to the lens of the monitor body 4, thus protecting the lens through the protective shell 34.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
