The connecting component includes a disassembly and assembly mechanism arranged on one side of the mounting plate. A protection mechanism is arranged on one side of the mounting plate, mounting holes are formed on the surface of the mounting plate, and one end of the first spring is fixedly connected to a rectangular block. This patent solves the problem that after the existing positioning device fixes the security monitoring, it is not convenient to disassemble it subsequently, thus not facilitating the manual maintenance and repair of the security monitoring later, and further affecting the applicability of the device.

[0004] However, the current positioning device has the following problems: This positioning device is not convenient for positioning, installing, and disassembling an inverted monitor. When disassembling the inverted monitor, it is prone to accidental dropping, resulting in damage to the monitor. Therefore, we propose a multi-angle security monitoring and positioning device. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-angle security monitoring and positioning device, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A multi-angle security monitoring and positioning device, including a mounting frame, a monitoring main body is provided at the bottom of the mounting frame, an installation groove is opened on one side of the monitoring main body, a positioning device is provided outside the mounting frame, the positioning device includes two elastic telescopic rods and a fixed disk, the fixed ends of the two elastic telescopic rods are respectively fixed on both sides of the mounting frame, and the telescopic ends of the two elastic telescopic rods are provided with an installation component for fixing the monitoring main body. The installation component includes a U-shaped rod, the U-shaped rod is fixed at the telescopic end of the elastic telescopic rod, a plug rod is fixed on one side of the U-shaped rod close to the mounting frame, the plug rod penetrates through the mounting frame, and the plug rod is inserted into the installation groove inside the monitoring main body. A limiting component is provided on the side of the U-shaped rod away from the mounting frame. Rounded corners are provided on both sides of the plug rod away from the U-shaped rod. Both sides of the installation groove are arranged as inclined surfaces. The fixed disk is embedded at the bottom of the mounting frame. L-shaped column rods are vertically penetrated and slidably installed on both sides of the fixed disk respectively, and a spring is provided between the top of the L-shaped column rod and the fixed disk. A push ring is fixed at the bottom of the L-shaped column rod. Four sliding grooves are evenly opened in a circular shape at the bottom of the fixed disk. L-shaped limiting rods are slidably installed in the four sliding grooves of the fixed disk respectively. One end of the L-shaped limiting rod away from the center of the fixed disk is hinged with a hinge rod, and one end of the hinge rod away from the L-shaped limiting rod is hinged at the inner wall of the push ring. Trapezoidal plates are fixed on the sides of the telescopic ends of the two elastic telescopic rods away from the mounting frame. An inclined angle is provided on one side of the bottom of the trapezoidal plate away from the fixed end of the elastic telescopic rod. The top end of the L-shaped column rod is arranged in a column shape, and the column shape of the L-shaped column rod is located on the movement track of the inclined angle of the trapezoidal plate. When the monitoring main body needs to be disassembled, pull the U-shaped rod in a direction away from the mounting frame. The U-shaped rod drives the telescopic end of the elastic telescopic rod to stretch. During this process, the elastic telescopic rod drives the trapezoidal plate to move accordingly. The inclined angle of the trapezoidal plate pushes the column shape of the L-shaped column rod to drive the L-shaped column rod to move downward. The L-shaped column rod pushes the push ring to move downward. The push ring pushes the hinge rod to drive the L-shaped limiting rod to move along the sliding groove of the fixed disk towards the center of the fixed disk. The L-shaped limiting rod forms an obstruction under the mounting seat of the monitoring main body.

[0007] According to the above technical solution, the limiting component includes a first screw block, the first screw block is fixed on the side of the U-shaped rod away from the mounting frame, a threaded insertion column penetrates through and is threadedly connected to the top of the first screw block, and a circular hole for accommodating the threaded insertion column is opened on the top of the fixed disk. When installing the monitoring main body, rotate the threaded insertion column. The threaded insertion column is affected by the thread of the first screw block and moves upward. The threaded insertion column is away from the circular hole of the fixed disk, and the threaded insertion column no longer restricts the position of the U-shaped rod.

[0008] According to the above technical solution, an auxiliary device is provided at the top of the mounting bracket. The auxiliary device includes a T-shaped disk, which is penetrated and slidably mounted on the top of the mounting bracket, and a spring is provided between the T-shaped disk and the top of the mounting bracket. A positioning disk is fixed to the bottom of the T-shaped disk. A circular groove for accommodating the positioning disk is provided at the top of the monitoring body. During the installation process of the monitoring body, the staff can first sleeved the circular groove of the monitoring body outside the positioning disk. During the process of inserting the monitoring body into the installation position of the mounting bracket, the positioning disk and the T-shaped disk will guide the monitoring body to be inserted into the installation position of the mounting bracket.

[0009] According to the above technical solution, cavities are provided in the middle parts of the T-shaped disk and the positioning disk. A suction cup tube is fixed inside the cavities of the T-shaped disk and the positioning disk. A plug rod is slidably mounted inside the suction cup tube. A threaded groove is provided on the outer wall above the plug rod. A second threaded block is fixed to the top of the T-shaped disk. The threaded groove of the telescopic plug rod is threadedly connected inside the second threaded block. When the circular groove of the monitoring body is sleeved outside the positioning disk, the plug rod is rotated. The threaded groove of the plug rod is restricted by the second threaded block, and the second threaded block drives the plug rod to move upward. The plug rod moves upward along the inside of the suction cup tube, and suction is generated at the suction cup tube to adsorb and fix the monitoring body, so that the monitoring body is fixed at the positioning disk.

[0010] According to the above technical solution, the auxiliary device further includes two push plates, two fixed shells, and two non-Newtonian body sacs. The two push plates are respectively fixed on both sides of the top of the T-shaped disk. The two fixed shells are both fixed on the top of the mounting bracket, and the two fixed shells are respectively located on both sides of the T-shaped disk. The two non-Newtonian body sacs are respectively fixed inside the two fixed shells. The non-Newtonian body sac is made of an elastic material. The non-Newtonian body sac is filled with a non-Newtonian body. The top of the non-Newtonian body sac is rounded. The rounded corner of the non-Newtonian body sac is located on the movement track of the push plate. At the same time, during the disassembly process of the monitoring body, since the monitoring body is fixed at the positioning disk, when the monitoring body moves downward, it will pull the positioning disk and the T-shaped disk downward. The T-shaped disk drives the push plate to move downward. When the staff does not notice whether the connection line of the monitoring body is removed and suddenly drags the monitoring body downward, the T-shaped disk drives the push plate to move downward rapidly, and the push plate quickly impacts the non-Newtonian body sac, and the non-Newtonian body sac hardens and hinders the push plate from moving downward.

[0011] The present invention provides a multi-angle security monitoring and positioning device. It has the following beneficial effects: (1) Through the setting of the positioning device in the present invention, the mounting frame, U-shaped rod, elastic telescopic rod, trapezoidal plate, L-shaped column rod, push ring, hinge rod, L-shaped limiting rod, and fixed disk cooperate to drive the L-shaped limiting rod to form an obstruction below the mounting seat of the monitoring body. Thus, it is ensured that when the monitoring body drops, it will be restricted by the L-shaped limiting rod. During the disassembly process of the monitoring body, the L-shaped limiting rod serves as an additional safety measure. Even if the disassembling personnel make an operation error and cause the monitoring body to drop, the L-shaped limiting rod can promptly restrict the dropping of the monitoring body, reducing the risk of personal injury and damage to the monitoring body. Therefore, it can provide additional a sense of security for the staff and improve the safety of the operation process.

[0012] (2) Through the setting of the auxiliary device in the present invention, the positioning disk and the T-shaped disk will guide the monitoring body to be inserted into the installation position of the mounting frame. The guiding function of the positioning disk and the T-shaped disk can help the monitoring body automatically align with the installation position, avoiding errors or inaccuracies during manual alignment. The staff only needs to simply insert the monitoring body without spending extra time adjusting the position. At the same time, the monitoring body, circular groove, positioning disk, plug rod, and screw block two cooperate to drive the plug rod to move upward along the inside of the suction cup tube, generating suction at the suction cup tube and adsorbing and fixing the monitoring body. Thus, the monitoring body is fixed at the positioning disk. When the monitoring body is not installed at the installation position of the mounting frame, the monitoring body will be hung below the mounting frame, enabling the staff to conveniently debug and test the monitoring body, ensuring the normal function of the monitoring device. This method can detect faults or problems of the monitoring body in advance, facilitating the staff to debug the monitoring body.

[0013] (3) Through the setting of the positioning disk, T-shaped disk, push plate, and non-Newtonian body capsule in the present invention, during the disassembly process of the monitoring body, the non-Newtonian body capsule hinders the rapid downward movement of the push plate, ensuring that the staff can only slowly drag the monitoring body downward. Thus, it avoids the problem that when the staff suddenly drags the monitoring body, the connection line of the monitoring body is damaged or broken due to too fast pulling.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0017] Please refer to Figure 1 - Figure 9 , an embodiment of the present invention is: a multi-angle security monitoring and positioning device, including a mounting bracket 1, a monitoring main body 2 is arranged at the bottom of the mounting bracket 1, and a mounting groove 21 is opened on one side of the monitoring main body 2 (as Figure 9As shown in the figure, a positioning device 3 is arranged outside the mounting bracket 1. The positioning device 3 includes two elastic telescopic rods 31 and a fixed disk 34. The fixed ends of the two elastic telescopic rods 31 are respectively fixed on both sides of the mounting bracket 1. The telescopic ends of the two elastic telescopic rods 31 are provided with a mounting component for fixing the monitoring main body 2. The mounting component includes a U-shaped rod 32. The U-shaped rod 32 is fixed at the telescopic end of the elastic telescopic rod 31. A plug rod 33 is fixed on one side of the U-shaped rod 32 close to the mounting bracket 1. The plug rod 33 penetrates through the mounting bracket 1, and the plug rod 33 is inserted into the mounting groove 21 inside the monitoring main body 2. A limiting component is arranged on the side of the U-shaped rod 32 away from the mounting bracket 1. Both sides of the plug rod 33 away from the U-shaped rod 32 are provided with rounded corners. Both sides of the mounting groove 21 are arranged as inclined surfaces. The fixed disk 34 is embedded and fixed at the bottom of the mounting bracket 1. L-shaped column rods 36 are respectively vertically penetrated and slidably mounted on both sides of the fixed disk 34, and a spring is arranged between the top of the L-shaped column rod 36 and the fixed disk 34. A push ring 35 is fixed at the bottom of the L-shaped column rod 36. Four sliding grooves are evenly arranged in a circular shape at the bottom of the fixed disk 34. L-shaped limiting rods 38 are slidably mounted inside the four sliding grooves of the fixed disk 34. One side of the L-shaped limiting rod 38 away from the center of the fixed disk 34 is hinged with a hinge rod 39. One end of the hinge rod 39 away from the L-shaped limiting rod 38 is hinged at the inner wall of the push ring 35. Trapezoidal plates 37 are fixed on the sides of the telescopic ends of the two elastic telescopic rods 31 away from the mounting bracket 1. An oblique angle is arranged on one side of the bottom of the trapezoidal plate 37 away from the fixed end of the elastic telescopic rod 31. The top end of the L-shaped column rod 36 is arranged in a columnar shape, and the columnar part of the L-shaped column rod 36 is located on the movement track of the oblique angle of the trapezoidal plate 37. When the monitoring main body 2 needs to be disassembled, through the setting of the above structure, the L-shaped limiting rod 38 forms an obstruction under the mounting seat of the monitoring main body 2, so as to ensure that the monitoring main body 2 will be restricted by the L-shaped limiting rod 38 when it falls. During the disassembly process of the monitoring main body 2, the L-shaped limiting rod 38 acts as an additional safety measure. Even if the disassembling personnel make an operation mistake and cause the monitoring main body 2 to fall, the L-shaped limiting rod 38 can timely restrict the fall of the monitoring main body 2, reducing the risk of personal injury and damage to the monitoring main body 2, so as to provide additional security for the staff and improve the safety of the operation process.

[0018] The limiting component includes a first screw block 310. The first screw block 310 is fixed on the side of the U-shaped rod 32 away from the mounting bracket 1. A threaded plug post 311 penetrates through and is threadedly connected to the top of the first screw block 310. A round hole for accommodating the threaded plug post 311 is opened at the top of the fixed disk 34. When installing the monitoring main body 2, rotate the threaded plug post 311. Under the threaded action of the first screw block 310, the threaded plug post 311 moves upward, the threaded plug post 311 is away from the round hole of the fixed disk 34, and the threaded plug post 311 no longer restricts the position of the U-shaped rod 32.

[0019] During use, when installing the monitoring main body 2, rotate the threaded plug post 311. Under the threaded action of the first threaded block 310, the threaded plug post 311 moves upward. The threaded plug post 311 moves away from the circular hole of the fixed disk 34, and the threaded plug post 311 no longer restricts the position of the U-shaped rod 32. Then, place the monitoring main body 2 below the mounting bracket 1 (i.e., the mounting part of the monitoring main body 2 has passed over the L-shaped limiting rod 38). Pull the U-shaped rod 32 in the direction away from the mounting bracket 1. The U-shaped rod 32 drives the telescopic end of the elastic telescopic rod 31 to stretch, and the U-shaped rod 32 drives the plug rod 33 away from the mounting bracket 1. Then, insert the monitoring main body 2 into the mounting position of the mounting bracket 1. After that, release the U-shaped rod 32. Under the elastic force of the elastic telescopic rod 31, the telescopic end of the elastic telescopic rod 31 drives the plug rod 33 to move back through the U-shaped rod 32, and the plug rod 33 is inserted into the mounting groove 21, thereby realizing the installation operation of the monitoring main body 2. When the monitoring main body 2 needs to be disassembled, pull the U-shaped rod 32 in the direction away from the mounting bracket 1. The U-shaped rod 32 drives the telescopic end of the elastic telescopic rod 31 to stretch. During this process, the elastic telescopic rod 31 drives the trapezoidal plate 37 to move along. The inclined angle of the trapezoidal plate 37 pushes the column of the L-shaped column rod 36 to drive the L-shaped column rod 36 to move downward. The L-shaped column rod 36 pushes the push ring 35 to move downward. The push ring 35 pushes the hinge rod 39 to drive the L-shaped limiting rod 38 to move along the sliding groove of the fixed disk 34 towards the center of the fixed disk 34. The L-shaped limiting rod 38 forms an obstruction below the mounting seat of the monitoring main body 2, thereby ensuring that the monitoring main body 2 will be restricted by the L-shaped limiting rod 38 when it falls. During the disassembly process of the monitoring main body 2, the L-shaped limiting rod 38 serves as an additional safety measure. Even if the disassembling personnel make an operation mistake and cause the monitoring main body 2 to fall, the L-shaped limiting rod 38 can promptly restrict the fall of the monitoring main body 2, reducing the risk of personal injury and damage to the monitoring main body 2, thereby providing an additional sense of security for the staff and improving the safety of the operation process.

[0020] Please refer to Figure 1 - Figure 9 Based on the above embodiments, in another embodiment of the present invention, an auxiliary device 4 is provided on the top of the mounting bracket 1.

[0021] The auxiliary device 4 includes a T-shaped disk 41 which penetrates and is slidably installed on the top of the mounting frame 1, and a spring is provided between the T-shaped disk 41 and the top of the mounting frame 1. A positioning disk 42 is fixed to the bottom of the T-shaped disk 41. A circular groove 22 for accommodating the positioning disk 42 is formed in the top of the monitoring body 2. During the installation process of the monitoring body 2, through the above structure, the positioning disk 42 and the T-shaped disk 41 will guide the monitoring body 2 to be inserted into the installation position of the mounting frame 1. The guiding function of the positioning disk 42 and the T-shaped disk 41 can help the monitoring body 2 automatically align with the installation position, avoiding errors or inaccuracies during manual alignment. The staff only needs to simply insert the monitoring body 2 without spending extra time adjusting the position.

[0022] Cavities are formed in the middle of both the T-shaped disk 41 and the positioning disk 42. A suction cup tube 43 is fixed inside the cavities of the T-shaped disk 41 and the positioning disk 42. A plug rod 44 is slidably installed inside the suction cup tube 43. A threaded groove is formed on the outer wall above the plug rod 44. A second threaded block 45 is fixed to the top of the T-shaped disk 41. The threaded groove of the telescopic plug rod 44 is threadedly connected inside the second threaded block 45. Through the above structure, the second threaded block 45 drives the plug rod 44 to move upward along the inside of the suction cup tube 43, generating suction at the suction cup tube 43 and adsorbing and fixing the monitoring body 2, so that the monitoring body 2 is fixed at the positioning disk 42. Thus, when the monitoring body 2 is not installed at the installation position of the mounting frame 1, the monitoring body 2 will be hung below the mounting frame 1, enabling the staff to conveniently debug and test the monitoring body 2 to ensure the normal function of the monitoring device. This way can detect faults or problems of the monitoring body 2 in advance, facilitating the staff to debug the monitoring body 2.

[0023] The auxiliary device 4 further includes two push plates 46, two fixed shells 47, and two non-Newtonian body sacs 48. The two push plates 46 are respectively fixed to both sides of the top of the T-shaped disk 41. The two fixed shells 47 are both fixed to the top of the mounting frame 1 and are respectively located on both sides of the T-shaped disk 41. The two non-Newtonian body sacs 48 are respectively fixed inside the two fixed shells 47. The non-Newtonian body sac 48 is made of elastic material and filled with non-Newtonian body. The top of the non-Newtonian body sac 48 is rounded, and the rounded corner of the non-Newtonian body sac 48 is located on the movement track of the push plate 46. During the disassembly process of the monitoring body 2, through the above structure, the non-Newtonian body sac 48 hinders the rapid downward movement of the push plate 46, ensuring that the staff can only slowly drag the monitoring body 2 downward, thus avoiding the problem that the connection line of the monitoring body 2 is damaged or broken due to too fast pulling when the staff suddenly drags the monitoring body 2.

[0024] During use, before installing the monitoring main body 2, the staff can first put the circular groove 22 of the monitoring main body 2 outside the positioning disk 42. Before inserting the monitoring main body 2 into the installation position of the mounting rack 1, the positioning disk 42 and the T-shaped disk 41 will guide the monitoring main body 2 to the installation position of the mounting rack 1. The guiding function of the positioning disk 42 and the T-shaped disk 41 can help the monitoring main body 2 automatically align with the installation position, avoiding errors or inaccuracies during manual alignment. The staff only needs to simply insert the monitoring main body 2 without spending extra time adjusting the position. When the circular groove 22 of the monitoring main body 2 is outside the positioning disk 42, rotate the plug rod 44. The threaded groove of the plug rod 44 is restricted by the second screw block 45, and the second screw block 45 drives the plug rod 44 to move upward. The plug rod 44 moves upward along the inside of the suction cup tube 43, generating suction at the suction cup tube 43 and adsorbing and fixing the monitoring main body 2, so that the monitoring main body 2 is fixed at the positioning disk 42. Thus, when the monitoring main body 2 is not installed at the installation position of the mounting rack 1, the monitoring main body 2 will be hung below the mounting rack 1, enabling the staff to conveniently debug and test the monitoring main body 2 to ensure the normal function of the monitoring device. This method can detect faults or problems of the monitoring main body 2 in advance, facilitating the staff to debug the monitoring main body 2. It should be noted that the above operations can be achieved by only one staff member. One hand of the staff holds the monitoring main body 2 so that the monitoring main body 2 abuts against the positioning disk 42, and then the other hand of the staff rotates the plug rod 44 to achieve the adsorption and fixing operation of the monitoring main body 2. At the same time, during the disassembly of the monitoring main body 2, since the monitoring main body 2 is fixed at the positioning disk 42, when the monitoring main body 2 moves downward, it will pull the positioning disk 42 and the T-shaped disk 41 downward. The T-shaped disk 41 drives the push plate 46 downward. When the staff does not notice whether the connection line of the monitoring main body 2 is removed and suddenly drags the monitoring main body 2 downward, the T-shaped disk 41 drives the push plate 46 to move downward rapidly. The push plate 46 quickly impacts the non-Newtonian body capsule 48, and the non-Newtonian body capsule 48 hardens and hinders the downward movement of the push plate 46, ensuring that the staff can only slowly drag the monitoring main body 2 downward, thus avoiding the problem that the connection line of the monitoring main body 2 is damaged or broken due to too fast pulling when the staff suddenly drags the monitoring main body 2.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
