[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 3A construction safety management device based on image recognition includes a base 1, a display 2, and a snap-fit ​​mechanism 3. The bottom of the display 2 is connected to a base 21, and the display 2 has an image recognition device. The base 1 has a receiving groove for accommodating the base 21, and the receiving groove is provided with an elastic support component 11 for supporting the base 21. The snap-fit ​​mechanism 3 is disposed on the base 1. When the base 21 is inserted into the receiving groove and the elastic support component 11 is pressed down to a designated position, the snap-fit ​​mechanism 3 restricts the movement of the base 21.

[0032] This invention achieves rapid assembly and disassembly of the display 2 through a base 1, a display 2, and a snap-fit ​​mechanism 3. When the display 2 is affected by dust or other factors, it can be quickly removed by disconnecting the snap-fit ​​mechanism 3. Then, the display 2 and the image recognition device mounted on it can be maintained. After maintenance, the base 21 of the display 2 is inserted into the receiving slot on the base 1. The elastic support component 11 and the snap-fit ​​mechanism 3 work together to restrict the movement of the base 21, completing the installation of the display 2. This solves the problem that traditional installation and management devices are easily affected by dust contamination, thus impacting image recognition accuracy. The base 1 is slidably mounted on a guide rail 4, which is equipped with a linear drive component 41 for driving the base 1 to translate along the guide rail 4. The linear drive component 41 includes a screw and a servo motor that drives the screw to rotate. The screw is threadedly connected to the base 1. When using this device, a display 2 needs to be installed for safety management. Align the base 21 connected to the bottom of the display 2 with the receiving groove on the base 1, and then insert the base 21 into the receiving groove. During the insertion process, the base 21 will press down the elastic support component 11 in the receiving groove. When the base 21 presses down the elastic support component 11 to the designated position, the locking mechanism 3 set on the base 1 locks with the base 21, restricting the movement of the base 21, thereby stably fixing the display 2 on the base 1. Then, the image recognition device on the display 2 can be used to perform identification work related to construction safety management. When the image recognition device is affected by dust or other factors, and maintenance of the display 2 and the image recognition device is required, simply release the locking mechanism 3 from the base 21. The pressed elastic support component 11 will spring upward, causing the base 21 to pop out of the receiving slot, and then the display 2 can be removed together. Maintenance of the display 2 and the image recognition device on it can then be performed. After maintenance, the base 21 is reinserted into the receiving slot, and the above operation is repeated. The elastic support component 11 is pressed down to the designated position, and the locking mechanism 3 restricts the movement of the base 21, thus completing the reinstallation of the display 2 and allowing for continued safety management. In operation, the servo motor is activated, driving the screw to rotate. The screw drives the base 1, which is threadedly connected to it, to move, thereby adjusting the position of the base 1 and the display 2.

[0033] Reference Figures 3 to 6The locking mechanism 3 includes a connecting ring 31, a vertical plate 32, and a locking block 33. The connecting ring 31 is disposed on the base 21, the vertical plate 32 is connected to the connecting ring 31, and the locking block 33 is disposed on the vertical plate 32. A pneumatic telescopic rod 12 is provided on the base 1. The end of the pneumatic telescopic rod 12 near the elastic support assembly 11 is provided with a connector 13 for cooperating with the locking block 33. When the connector 13 cooperates with the locking block 33, it restricts the movement of the locking block 33 and the connecting ring 31.

[0034] This invention, through the cooperation of connecting ring 31, upright plate 32, locking block 33, pneumatic telescopic rod 12, and connector 13, achieves the functions of stably restricting the movement of base 21 and quickly releasing the locking mechanism. This enables rapid assembly and disassembly of display 2 and further improves the stability of display 2, ensuring the normal operation of the image recognition device and reducing the difficulty of safety management and maintenance in construction projects. It solves the technical problem of traditional locking mechanisms 3 being insecure, easily causing display 2 to shake, affecting image recognition accuracy and thus impacting safety management efficiency. Multiple locking mechanisms 3 and pneumatic telescopic rods 12 are provided, and multiple pneumatic telescopic rods 12 are connected to the same air source. When installing the monitor 2 using this device, align the base 21 at the bottom of the monitor 2 with the receiving slot on the base 1 and insert it. The base 21 will move the connecting ring 31 connected to it. The connecting ring 31 will move the connected upright plate 32 and the locking block 33 on the upright plate 32 synchronously. At the same time, the base 21 presses down on the elastic support component 11 in the receiving slot. When the base 21 presses the elastic support component 11 down to the designated position, it will move the connecting piece 13 near the end of the elastic support component 11 until the connecting piece 13 engages with the locking block 33. The connecting piece 13 locks the locking block 33, thereby restricting the movement of the locking block 33 and the connecting ring 31. The connecting ring 31 connects to the base 21, thereby restricting the movement of the base 21 and stably fixing the monitor 2 on the base 1. At this time, the image recognition device on the monitor 2 can normally carry out the recognition work of building engineering safety management. When it is necessary to maintain the monitor 2 and When the image recognition device is in operation, the pneumatic telescopic rod 12 is controlled to be under negative pressure. The air pressure force causes the connector 13 to disengage from the locking block 33, releasing the restriction on the locking block 33 and the connecting ring 31. The pressed elastic support component 11 springs upward, causing the base 21, connecting ring 31, upright plate 32, and locking block 33 to move upward together, causing the base 21 to pop out of the receiving slot, thereby removing the display 2. Then, the display 2 and the image recognition device on it can be maintained. After maintenance, the base 21 is inserted back into the receiving slot. The base 21 moves the connecting ring 31, upright plate 32, and locking block 33 synchronously and presses down the elastic support component 11. When it reaches the designated position, the pneumatic telescopic rod 12 causes the connector 13 to engage with the locking block 33, re-restricting the movement of the locking block 33, connecting ring 31, and base 21, completing the reinstallation of the display 2, and continuing the safety management work.

[0035] Reference Figures 5 to 7The connector 13 is rotatably provided with a locking post 131; the locking block 33 is provided with a first inclined surface 331 and an abutting surface 332. When the connector 13 passes the first inclined surface 331, the locking post 131 abuts against the abutting surface 332 and restricts the movement of the locking block 33.

[0036] This invention achieves the functions of quick engagement and stable restriction of movement of the locking mechanism 3 by the cooperation of the locking post 131, the first inclined surface 331 and the abutment surface 332. This further improves the operational stability of the device and ensures the normal operation of the image recognition device. It solves the technical problems of easy jamming and loosening when the connector 13 and the locking block 33 of the traditional locking mechanism 3 are engaged, which can lead to unstable fixation and shaking of the display 2 and affect the accuracy of image recognition. When installing the monitor 2, align the base 21 at the bottom of the monitor 2 with the receiving groove on the base 1 and insert it. The base 21 drives the connecting ring 31, the upright plate 32 and the locking block 33 on the upright plate 32 to move synchronously. At the same time, the base 21 presses down on the elastic support component 11 in the receiving groove. At this time, the pneumatic telescopic rod 12 is in a positive pressure state. When the locking post 131 contacts the first inclined surface 331, it is squeezed. The pneumatic telescopic rod 12 retracts under pressure. When the base 21 presses down the elastic support component 11 to the designated position, the locking post 131 crosses the first inclined surface 331 and fits against the abutment surface 332 on the locking block 33. The abutment surface 332 prevents the locking post 131 from moving in the opposite direction, thereby restricting the movement of the locking block 33 and the connecting ring 31. The connecting ring 31 is connected to the base 21, thereby firmly restricting the base 21 in the receiving groove. The monitor 2 is stably fixed on the base 1. At this time, the image recognition device on the monitor 2 can carry out the construction engineering safety management recognition work normally. When maintenance of the display 2 and the image recognition device is required, the pneumatic telescopic rod 12 is activated, which moves the connector 13 away from the locking block 33. The locking pin 131 on the connector 13 disengages from the contact surface 332 of the locking block 33, releasing the restriction on the locking block 33 and the connecting ring 31. The pressed elastic support component 11 springs upward, causing the base 21, the connecting ring 31, the upright plate 32 and the locking block 33 to move upward together, so that the base 21 pops out of the receiving slot, thereby taking out the display 2. Then the display 2 and the image recognition device on it can be maintained.

[0037] Reference Figure 4 , Figure 5 and Figure 8 The elastic support assembly 11 includes an annular support 111 and an elastic element 112; the annular support 111 is vertically and flexibly disposed in the receiving groove of the base 1; the two ends of the elastic element 112 are respectively connected to the annular support 111 and the base 1.

[0038] This invention, through the cooperation of the annular support 111 and the elastic element 112, achieves the functions of buffering the impact force when the base 21 is inserted and protecting the device components. This results in stable support for the base 21, smoother assembly and disassembly of the display 2, and avoidance of component wear to ensure the normal operation of the image recognition device. It solves the technical problem that the impact force during base 21 insertion easily leads to component wear, affecting the ease of assembly and disassembly of the display 2 and the lifespan of the device. When using this device to install the display 2, align the base 21 at the bottom of the display 2 with the receiving groove on the base 1 and insert it. The base 21 will first contact the adjustable annular support 111 in the receiving groove. As the base 21 continues to be inserted, it will cause the annular support 111 to move downwards. When the annular support 111 moves, it will compress the elastic element 112 connected to its two ends. The compression of the elastic element 112 not only buffers the impact force of the base 21 on the base 1 and itself during insertion, protecting the base 21, the annular support 111, and the base 1 from wear, but also provides upward support to the annular support 111 through its own elasticity, ensuring that the base 21 is always stably supported. When the base 21 presses the annular support 111 down to the designated position, the locking mechanism 3 on the base 1 is activated, restricting the movement of the base 21 and stably fixing the monitor 2 on the base 1. At this time, the annular support 111, supported by the elastic element 112, always fits against the bottom of the base 21, keeping the base 21 stable and preventing the monitor 2 from shaking. This ensures that the image recognition device on the monitor 2 can carry out its construction safety management identification work normally. When it is necessary to maintain the monitor 2 and the image recognition device, the locking mechanism 3 is released from the base 21. The compressed elastic element 112 will spring back upward, causing the annular support 111 to move upward as well. When the annular support 111 moves upward, it will push the base 21, popping the base 21 out of the receiving slot, and then taking the monitor 2 out together. This eliminates the need to manually lift the monitor 2 with effort, facilitating quick disassembly of the monitor 2.

[0039] Reference Figures 5 to 7 The connector 13 has two locking posts 131. After the connector 13 passes the first inclined surface 331, both locking posts 131 abut against the contact surface 332.

[0040] This invention achieves the function of uniform force distribution and more stable restriction of the movement of the card block 33 by synchronously engaging the two card posts 131 with the contact surface 332 of the card block 33. This results in more reliable card fixing, no shaking of the display 2 after installation, and effectively avoids loosening or component wear caused by uneven force distribution on a single card post 131. This further ensures the normal operation of the image recognition device and solves the technical problem of concentrated force distribution and easy loosening of the traditional single card post 131, which causes the display 2 to shake and affect the image recognition accuracy. When installing the monitor 2, align the base 21 at the bottom of the monitor 2 with the receiving groove on the base 1 and insert it. The base 21 drives the connecting ring 31, the upright plate 32, and the locking block 33 on the upright plate 32 to move synchronously. At the same time, the base 21 presses down on the annular support 111 in the receiving groove and compresses the elastic member 112. When the base 21 presses the elastic support assembly 11 to the designated position, the pneumatic telescopic rod 12 on the base 1 drives the connecting member 13 at its end to move towards the locking block 33. The two locking posts 131 rotatably set on the connecting member 13 will synchronously contact the first inclined surface 331 on the locking block 33. As the connecting member 13 continues to move, the two locking posts 131 will contact the first inclined surface 331 on the locking block 33. The column 131 slides and rotates on the first inclined surface 331 at the same time. Meanwhile, the pneumatic telescopic rod 12 is compressed and retracts. After successfully passing the first inclined surface 331, the two locking columns 131 simultaneously abut against the contact surface 332 on the locking block 33, and the two-way synchronous limiting makes the locking block 33 evenly stressed, avoiding the loosening of the locking caused by the concentrated force on a single locking column 131. This further restricts the movement of the locking block 33 and the connecting ring 31 more stably. The connecting ring 31 is connected to the base 21, thereby firmly fixing the base 21 in the receiving groove. The display 2 is stably fixed on the base 1. At this time, the image recognition device on the display 2 can carry out the construction engineering safety management recognition work normally.

[0041] Reference Figures 7 to 10 The card block 33 has a second inclined surface 333, which is located above the abutment surface 332.

[0042] This invention, through the second inclined surface 333 on the locking block 33, in conjunction with the locking post 131, the abutment surface 332, the pneumatic telescopic rod 12, and the elastic support assembly 11, achieves the movement buffering of the display 2 when subjected to downward pressure. At the same time, it can automatically control the upward movement and reset of the display 2 and the base 21 without affecting the function of the locking mechanism 3 in restricting the upward movement of the base 21. This achieves the effect of buffering and protecting the display 2 and device components, and avoiding damage from pressure. It solves the technical problem that the traditional locking mechanism 3 has no buffering structure, and the display 2 is easily damaged by hard force when subjected to downward pressure, which affects the safety management effect of building engineering. In operation, when the monitor 2 is subjected to downward pressure, the pressure is transmitted to the base 21, causing the base 21 to move downward. The base 21 then moves the locking block 33 downward simultaneously. The locking pin 131, which engages with the contact surface 332, rolls along the second inclined surface 333 of the locking block 33, which is located above the contact surface 332. As the locking pin 131 rolls, it pushes the connecting piece 13 away from the locking block 33, thus applying pressure to the pneumatic telescopic rod 12. Simultaneously, the base 21 continues to press down on the annular support 111, causing the elastic element 112 to further contract. The annular support 111 moves downward synchronously. Through the contraction of the elastic element 112 and the rolling of the locking pin 131 along the second inclined surface 333, the monitor 2 is subjected to pressure. The downward pressure is buffered to prevent damage to components such as the display 2, the locking block 33, and the locking post 131 due to rigid force. When the downward pressure on the display 2 disappears, the elastic element 112, which has been further compressed, will rebound upward, causing the ring support 111 to move upward and pushing the base 21 upward. At the same time, the pneumatic telescopic rod 12, which has been compressed, is reset, causing the connecting piece 13 to move towards the locking block 33. The locking post 131 rolls back along the second inclined surface 333 and re-fits with the abutment surface 332 of the locking block 33, restricting the upward movement of the base 21. This achieves automatic upward movement and reset of the display 2 and the base 21. After reset, the display 2 remains in a stable and fixed state, and the image recognition device can continue to work normally.

[0043] Reference Figures 7 to 10 The locking block 33 is provided with a third inclined surface 334, and there is a gap between the connecting ring 31 and the locking block 33 for the locking post 131 to pass through; when the connecting piece 13 moves upward relative to the locking block 33 and passes over the second inclined surface 333, the pneumatic telescopic rod 12 extends and moves to the third inclined surface 334.

[0044] This invention utilizes the third inclined surface 334 to guide the movement of the locking post 131. In operation, the locking post 131 abuts against the contact surface 332, and the pneumatic telescopic rod 12 is in its natural state, thus preventing the base 21 from disengaging from the receiving groove. When maintenance of the display 2 is required, the operator manually or with tools presses down on the display 2, causing the base 21 to move the connecting ring 31 downwards synchronously. At this time, the locking post 131 on the connector 13 rolls along the second inclined surface 333, and the pneumatic telescopic rod 12 retracts from its natural state. After the connector 13 passes the second inclined surface 333, it extends under pneumatic pressure. Next, the elastic element 112 releases its elastic potential energy, and the connecting ring 31 and the upright plate 32 move upward under the pushing action of the elastic support assembly 11. During the upward movement, the locking pin 131 rolls along the third inclined plane 334. At this time, the pneumatic telescopic rod 12 is stretched under the squeezing action of the third inclined plane 334. After the locking pin 131 passes the third inclined plane 334, it moves to the vertical surface of the locking block 33, releasing the locking engagement between the locking block 33 and the locking pin 131, and moves upward under the elastic pushing action of the elastic support assembly 11. After the locking pin 131 separates from the locking block 33, the pneumatic telescopic rod 12 retracts and drives the locking pin 131 and the connecting piece 13 to reset. By setting the third inclined plane 334 to avoid repeated adjustment of the air pressure of the pneumatic telescopic rod 12, the pneumatic telescopic rod 12 only needs to achieve the function of a gas spring to realize the quick assembly and disassembly of the display 2.

[0045] Reference Figure 8 The base 1 has a accommodating groove equipped with a limiting rod 14 and a linear actuator 15 for adjusting the height of the limiting rod 14.

[0046] This invention, through the limiting rod 14 and the linear actuator 15, achieves the functions of adjusting the height of the limiting rod 14 and limiting the excessive lifting and lowering of the annular support 111, thereby protecting the elastic component 112, improving the adaptability of the device, ensuring the accurate positioning of the annular support 111, and extending the service life of the device. In use, the height of the limiting rod 14 can be adjusted via the linear actuator 15 to a suitable position according to the height of the base 21, preventing the annular support 111 from excessively lowering and damaging the elastic component 112. When the base 21 is inserted into the receiving groove and the annular support 111 is pressed down, the limiting rod 14 will restrict further downward movement when the annular support 111 contacts the limiting rod 14. At this point, the base 21 reaches the designated position, facilitating the locking mechanism 3 to smoothly fix the base 21. When adapting to bases 21 of different heights, only the height of the limiting rod 14 needs to be adjusted via the linear actuator 15; there is no need to replace the elastic support component 11, thus improving the versatility of the device. In operation, by adjusting the height of the limiting rod 14, the connecting ring 31 is prevented from moving downwards excessively, which could cause the locking post 131 to cross the second inclined surface 333, thus preventing the monitor 2 from accidentally detaching from the receiving slot during use. When disassembling the monitor 2, the linear driver 15 is activated to control the limiting rod 14 to move downwards, and then the base 21 is pressed down to disassemble the monitor 2.

[0047] Reference Figure 8 The inner wall of the receiving groove of the base 1 is provided with guide strips 16 for guiding the movement of the upright plate 32.

[0048] This invention, through the guide bar 16, enables the upright plate 32 to move synchronously and smoothly with the base 21, preventing the upright plate 32 from shifting or jamming, further improving the stability and convenience of installing and fixing the monitor 2, and preventing damage to components due to the upright plate 32 shifting. In use, when the monitor 2 is inserted into the base 21, the base 21 drives the connecting ring 31 and the upright plate 32 to move synchronously into the receiving groove. At this time, the guide bar 16 on the inner wall of the receiving groove of the base 1 begins to function, guiding the upright plate 32 to move smoothly along the direction of the guide bar 16, preventing the upright plate 32 from shifting to either side or jamming during movement, ensuring that the locking block 33 on the upright plate 32 is always aligned with the connector 13 at the end of the pneumatic telescopic rod 12; when the base 21 presses down the elastic support assembly 11 to the designated position, under the guidance of the guide bar 16, the upright plate 32 and the locking block 33 are accurately positioned, and the connector 13 can smoothly cooperate with the locking block 33 to quickly complete the locking and fixing, ensuring stable installation of the monitor 2. The guide bar 16 only serves to guide the movement of the upright plate 32. Without additional operation, the upright plate 32 can be moved accurately and smoothly. This not only improves the convenience and efficiency of disassembling and assembling the display 2, but also avoids various problems caused by the offset of the upright plate 32, making the device more reliable.

[0049] Reference Figure 2 and Figure 3 The connecting ring 31 is rotatably connected to the base 21, and the base 21 is provided with a rotary driver for driving the connecting ring 31 to rotate.

[0050] This invention achieves flexible adjustment of the shooting angle of the display 2 by rotatably connecting the connecting ring 31 to the base 21 and driving the connecting ring 31 to rotate with the rotation driver. Combined with the limiting effect of the upright plate 32 and the guide strip 16, this allows for precise adjustment of the shooting angle. When the shooting angle of the display 2 needs to be adjusted to adapt to different construction safety recognition scenarios, the rotation driver is activated, driving the connecting ring 31 to rotate. Since the upright plate 32 on the connecting ring 31 is restricted in its rotation due to its interaction with the guide strip 16, the base 21 and the display 2 are driven to rotate on the connecting ring 31. After adjusting to a suitable shooting angle, the rotation driver is turned off, further improving the device's functionality, adaptability, and practicality, and ensuring the efficient operation of image recognition work for construction safety management.
