Description

Technical Field

[0001] The utility model relates to the technical field of Internet of Things, in particular to an adjusting monitoring bracket for Internet of Things security. Background Art

[0002] The Internet of Things refers to connecting any object to the network through information sensing devices according to agreed protocols. Objects exchange and communicate information through information dissemination media to achieve intelligent identification, positioning, tracking, supervision and other functions.

[0003] In order to achieve network connection between objects in the Internet of Things, monitors are needed. Monitors are generally installed on the wall through brackets. Monitors can be automatically adjusted at various angles to perceive the identified objects from multiple angles. Monitors are usually installed at a higher position on the wall. During installation and when maintenance, inspection and disassembly are required, climbing tools such as ladders are required to perform climbing operations. People climb up and down, which increases the risk of construction. Therefore, installation and disassembly are troublesome and time-consuming.

[0004] After searching, the Chinese patent with publication number CN210979252U discloses an adjustable monitoring bracket for IoT security, in which a rotating seat is arranged at the top of the I-shaped support frame. The design is novel and the structure is simple, which is convenient for the staff to adjust the camera well to meet people's different needs for the camera, and has a good shock-absorbing effect, so that the camera is not easily damaged when it vibrates, which is more practical.

[0005] The above solution solves the problem of people being able to adjust the illumination angle or direction of the camera well, but since the monitor is installed at a high position, it is not convenient to install and disassemble.

[0006] Therefore, new solutions are needed to solve this problem Utility Model Content

[0007] In view of the above background technology, the shortcomings and defects of the existing technology that the monitor is not easy to install and disassemble.

[0008] The utility model discloses an adjustable monitoring bracket for Internet of Things security, comprising a base, a monitor mounted on the upper end surface of the base, two connecting rods hingedly connected to the front side surface of the base, a mounting plate hingedly connected to the other ends of the two connecting rods, the mounting plate being fixedly arranged on a wall, the two connecting rods being arranged in parallel, a buckle mechanism being arranged on the front side surface of the base, and when the base moves upward until the two connecting rods are in a horizontal state, the buckle mechanism is engaged with the connecting rods.

[0009] By adopting the above scheme, the buckle mechanism is firstly disengaged from the connecting rod, and then the base moves downward under the restriction of the two connecting rods. During the movement, the two connecting rods are always in a parallel state, so that the upper end surface of the base is always in a horizontal state during the movement. When the two connecting rods are rotated downward to a vertical state, the base moves downward to the lowest state. At this time, the monitor can be conveniently installed on the base. After the monitor is installed, the two connecting rods are driven to rotate counterclockwise to make the base move upward. During the movement, the upper end surface of the base is always in a horizontal state. Until the two connecting rods are in a horizontal state, the buckle The mechanism engages with the connecting rod to stop rotation, and the base is now in the set position, so that the monitor is in the required installation position, completing the installation of the monitor. The set up of the liftable base makes it more convenient to install the monitor on the base without the need for climbing tools, thereby improving construction safety and installation efficiency. When the monitor needs to be repaired and inspected, the snap mechanism is disengaged from the connecting rod, and the base can then move downward until the two connecting rods are in a vertical state and the base moves to the lowest position, at which point the monitor can be easily disassembled for repair and inspection.

[0010] Optionally, the snap mechanism includes a locking rod hinged to the front side of the base, and a fixing pin fixed to the rear side of the connecting rod, a driving surface is provided at the top of the locking rod, a slot is provided on the left side of the locking rod, a limiting mechanism is provided between the locking rod and the base, and a spring is provided between the locking rod and the base.

[0011] By adopting the above solution, the spring drives the locking rod to rotate counterclockwise all the time, and the limiting mechanism restricts the locking rod from rotating counterclockwise. With the cooperation of the spring and the limiting mechanism, the locking rod is in a state of being parallel to the Z axis and deviating to the left by a set angle. When the monitor is installed on the base, the base is moved upward and the two connecting rods in the vertical state also start to rotate. During the movement, the upper end surface of the base is always in a horizontal state, and the two connecting rods slowly cross the locking rod as they move. When the fixed pin on the connecting rod contacts the top of the locking rod, the fixed pin contacts the driving surface of the locking rod, causing the locking rod to rotate clockwise until the fixed pin contacts the left side of the locking rod. As the connecting rod continues to move, the fixed pin fits the left side of the locking rod and continues to move downward relative to the locking rod until the fixed pin is inserted into the slot of the locking rod. The locking rod is in a state of being deviated from parallel to the Z axis to the left by a set angle. The set angle here is based on the ability of the fixed pin to cooperate with the driving surface to drive the locking rod to rotate clockwise. The angle range between the locking rod and the Z axis in which the fixing pin and the driving surface can cooperate to drive the locking rod to rotate clockwise belongs to the set angle.

[0012] Optionally, a pull rod is hinged on the top of the locking rod, a slider is hinged on the middle section of the pull rod, the slider is slidably connected to the upper end surface of the base in the left and right directions, a fixed block is provided on the right side of the upper end surface of the base, the connecting rod passes through a vertical through slot opened on the fixed block, and the spring is sleeved on the pull rod between the fixed block and the slider.

[0013] By adopting the above scheme, the spring is in a compressed state, the spring drives the slider to move to the left, the slider drives the pull rod to move to the left, the pull rod pushes the locking rod to rotate counterclockwise, and the limit mechanism limits the locking rod from rotating counterclockwise, so that the locking rod remains in a state where the locking rod is parallel to the Z-axis and deviates to the left by a set angle. When the monitor needs to be repaired and inspected, the pull rod is pulled to the right so that the pull rod drives the locking rod to rotate clockwise. At the same time, the slider will also move to the right on the base, and the pull rod and the slider rotate adaptively with each other. The locking rod rotates clockwise, so that the fixing pin of the connecting rod disengages from the slot of the locking rod, and then the base can move downward. When the base moves to the lowest position, the monitor can be disassembled and then repaired and inspected.

[0014] Optionally, the limiting mechanism includes a guide rail arranged on the lower end surface of the slider and a guide groove opened on the upper end surface of the base, and the slider is slidably connected to the base via the guide rail and the guide groove.

[0015] By adopting the above solution, the side wall at the left end of the guide groove limits the guide rail from moving to the left. By setting the guide rail and the guide groove, when the slider moves left and right on the base, the guide rail slides in the guide groove, which increases the stability of the slider moving on the base. At the same time, the side wall at the left end of the guide groove limits the guide rail from moving further to the left, thereby limiting the slider from moving further to the left when it moves to the left end of the guide groove through the guide rail. When the spring pushes the locking rod to rotate counterclockwise, the guide groove limits the guide rail, so that the locking rod is kept in a state where the locking rod is parallel to the Z axis and deviates to the left by a set angle.

[0016] Optionally, a rope is provided at the right end of the pull rod, a guide rod is provided on the right side surface of the base, a pulley is hinged at the right end of the guide rod, and the rope is connected to the pulley by transmission.

[0017] By adopting the above solution, by pulling down the bottom end of the rope, the rope is guided by the pulley and the pull rod is pulled by the left end of the rope, so that the pull rod moves to the right, thereby achieving the purpose of driving the pull rod to move to the right.

[0018] Optionally, a hinge shaft where one of the connecting rods is hinged to the mounting plate extends outward to the front of the mounting plate and is provided with a first gear, the hinge shaft is fixed to the corresponding connecting rod, the front side surface of the mounting plate is rotatably connected to a second gear, and the second gear is meshed with the first gear.

[0019] By adopting the above solution, the first gear is driven to rotate by driving the second gear to rotate, so that the first gear drives the connecting rod to rotate through the hinge shaft, thereby achieving the purpose of driving the connecting rod to rotate.

[0020] Optionally, a first bevel gear is provided on the front side of the second gear, and a transmission rod is provided on the right side surface of the wall in the vertical direction, and the transmission rod is rotatably connected to the wall through a fixed plate provided on the wall; a second bevel gear is fixedly provided on the top of the transmission rod, and a handwheel is provided at the bottom end of the transmission rod, and the second bevel gear is meshed with the first bevel gear.

[0021] By adopting the above solution, when in use, the hand wheel is turned to drive the transmission rod to rotate, so that the transmission rod drives the second gear to rotate through the second bevel gear and the first bevel gear, and then drives the first gear to rotate, and then drives the connecting rod to rotate, thereby achieving the purpose of driving the second gear to rotate.

When the base 1 moves upward until the two connecting rods 3 are in a horizontal state, the buckle mechanism is engaged with the connecting rod 3.

[0035] During installation, first disengage the buckle mechanism from the connecting rod 3, and then the base 1 moves downward under the restriction of the two connecting rods 3. During the movement, the two connecting rods 3 are always in a parallel state, so that the upper end surface of the base 1 is always in a horizontal state during the movement. When the two connecting rods 3 are rotated downward to a vertical state, the base 1 moves downward to the lowest state. At this time, the monitor 2 can be easily installed on the base 1. After the monitor 2 is installed, the two connecting rods 3 are driven to rotate counterclockwise to make the base 1 move upward. During the movement, the upper end surface of the base 1 is always in a horizontal state.

At this time, the base 1 is also in the set position, so that the monitor 2 is in the required installation position, and the installation of the monitor 2 is completed. The set liftable base 1 makes it more convenient to install the monitor 2 on the base 1 without climbing tools, thereby improving construction safety and installation efficiency. When the monitor 2 needs to be repaired and inspected, the buckle mechanism is disengaged from the connecting rod 3, and then the base 1 can move downward until the two connecting rods 3 are in a vertical state and the base 1 moves to the lowest position. At this time, the monitor 2 can be easily disassembled for maintenance and inspection.

[0036] In this embodiment, the snap mechanism includes a locking rod 6 hinged on the front side of the base 1, and a fixing pin 7 fixed to the rear side of the connecting rod 3.

With the cooperation of the spring 10 and the limiting mechanism, the locking rod 6 is in a state of being deviated to the left by a set angle from being parallel to the Z axis. When the monitor 2 is installed on the base 1, the base 1 is moved upward, and the two connecting rods 3 in the vertical state also start to rotate. During the movement, the upper end surface of the base 1 is always in a horizontal state, and the two connecting rods 3 slowly cross the locking rod 6 as they move. When the fixing pin 7 on the connecting rod 3 contacts the top of the locking rod 6, the fixing pin 7 contacts the driving surface 8 of the locking rod 6, so that the locking rod 6 rotates clockwise until the fixing pin 7 contacts the left side surface of the locking rod 6. As the connecting rod 3 continues to move, the fixing pin 7 fits the left side surface of the locking rod 6 and continues to move downward relative to the locking rod 6 until the fixing pin 7 is stuck in the slot 9 of the locking rod 6; the locking rod 6 is in a state of being deviated from parallel to the Z axis to the left by a set angle. The set angle here is based on the ability of the fixing pin 7 to cooperate with the driving surface 8 to drive the locking rod 6 to rotate clockwise. The angle range between the locking rod 6 and the Z axis in which the fixing pin 7 and the driving surface 8 can cooperate to drive the locking rod 6 to rotate clockwise belongs to the set angle.

[0037] In this embodiment, the driving surface 8 is an arc surface.

[0038] In this embodiment, the driving surface 8 is an inclined surface.

[0039] In order to drive the locking rod 6 to rotate clockwise so that the fixing pin 7 disengages from the slot 9 and the buckle mechanism is disengaged from the connecting rod 3, in this embodiment, a pull rod 11 is hinged on the top of the locking rod 6, a slider 12 is hinged on the middle section of the pull rod 11, the slider 12 is slidably connected to the upper end surface of the base 1 in the left and right directions, a fixing block 13 is provided on the right side of the upper end surface of the base 1, the connecting rod 3 passes through a vertical through groove 14 provided on the fixing block 13, and a spring 10 is sleeved on the pull rod 11 between the fixing block 13 and the slider 12; the spring 10 is in a compressed state, the spring 10 drives the slider 12 to move to the left, the slider 12 drives the pull rod 11 to move to the left, and the pull rod 11 pushes The locking rod 6 rotates counterclockwise, and the limit mechanism restricts the locking rod 6 from rotating counterclockwise, so that the locking rod 6 remains in a state where the locking rod 6 is parallel to the Z axis and deviates to the left by a set angle. When the monitor 2 needs to be repaired and inspected, the pull rod 11 is pulled to the right, so that the pull rod 11 drives the locking rod 6 to rotate clockwise, and the slider 12 also moves to the right on the base 1, and the pull rod 11 and the slider 12 rotate adaptively with each other, and the locking rod 6 rotates clockwise, so that the fixing pin 7 of the connecting rod 3 is disengaged from the card slot 9 of the locking rod 6, and then the base 1 can move downward.

At this time, the base 1 moves to the lowest position, and then it can be conveniently disassembled. Remove the monitor 2, perform maintenance and inspection on it, then install the monitor 2 on the base 1, and then turn the hand wheel to move the base 1 upward until the two connecting rods 3 are in a horizontal state. During the movement of the two connecting rods 3, the fixing pin 7 moves to contact the driving surface 8 at the top of the locking rod 6, and cooperates with the driving surface 8 to make the locking rod 6 rotate clockwise, and then the fixing pin 7 continues to move downward relative to the locking rod 6 until it enters the slot 9 of the locking rod 6, limiting the rotation of the connecting rod 3. At this time, the two connecting rods 3 are just in a horizontal state, and the base 1 is also in the set position, so that the monitor 2 enters the working position.
