Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a fire monitoring device which is easy to install. Background Art

[0002] Fire monitoring devices are equipment used to monitor and manage fire safety in real time, aiming to improve the efficiency of fire warning and response. These devices usually include fire detectors, automatic alarm systems, surveillance cameras and fire control systems. Fire detectors can detect fire sources in real time by detecting smoke, heat or flames. Once an abnormality occurs, they will automatically send an alarm to the control system. After receiving the alarm, the control system will immediately activate fire-fighting equipment, such as sprinkler systems or fire extinguishers, and notify relevant personnel or the fire department for processing.

[0003] Fire monitoring cameras can transmit on-site images in real time, helping operators and fire departments to remotely view fire conditions and make more accurate decisions. However, there are still certain problems: fire monitoring can assist off-site personnel in fire control, but fire monitoring cameras are easily damaged by the harsh environment in the fire scene. For fire scenes that have been extinguished, fire monitoring can be reinstalled to assist off-site control, but the assembly is difficult and time-consuming. Therefore, in view of the above situation, there is an urgent need to develop a fire monitoring device that is easy to install to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the present invention is to provide a fire monitoring device that is easy to install, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a fire monitoring device that is easy to install, comprising a monitoring device, a mounting plate, a mounting base, and a docking plate, wherein the monitoring device is fixedly mounted on the bottom of the mounting plate, the mounting plate is fixedly mounted on the bottom of the docking plate, and the docking plate is embedded in the bottom of the mounting base;

[0006] A three-in-one joint is provided in the middle of the mounting base, a positioning hole and a locking groove are provided on the bottom edge of the mounting base, a locking assembly is embedded in the locking groove, a sealing cover is embedded in the edge of the locking groove, and a sleeve is provided in the middle of the sealing cover;

[0007] The locking assembly includes a rotor, a pawl a, a one-way toothed disc, a spring, a driving disc, a lever arm, a top plate, a ratchet and a pawl b. The rotor is horizontally arranged inside the locking groove and is rotatably connected to the locking groove. Three pawls a are annularly equidistantly hinged to the outside of the rotor. The one-way toothed disc is sleeved on the middle section of the rotor and fixedly connected to the rotor. The spring is obliquely installed on the inner wall of the locking groove. The driving disc is installed on the inside of the locking groove and is rotatably connected to the locking groove. The bottom end of the lever arm is welded to the top edge of the driving disc. The top plate is horizontally fixed to the top edge of the lever arm. The ratchet is sleeved on the end of the rotor and achieves an interference fit with the rotor. The pawl b is installed inside the driving disc, and the pawl b is adapted to the ratchet.

[0008] Preferably, three pins are fixed to the top edge of the docking tray, a three-hole socket is passed through the middle of the top of the docking tray, an inner groove is provided at the bottom of the docking tray, and the three-hole socket passes through and extends to the part of the bottom of the docking tray and is installed with terminal posts. Specifically, the terminal posts are used to connect to the power supply, signal and other lines of the monitoring equipment, and the inner groove is used to adapt to the top of the monitoring equipment to achieve sealed protection of the connection parts and lines.

[0009] Preferably, the exterior of the pawl a is an arc-shaped structure, and a torsion spring is installed at the hinged portion between the pawl a and the rotor. Specifically, the torsion spring and its arc-shaped structure can drive the pawl a to adapt to the bayonet position of the pin shaft to achieve one-way limiting.

[0010] Preferably, the end of the spring piece is matched with the tooth groove of the one-way gear disc. Specifically, the spring piece can limit the one-way gear disc so that it can only rotate clockwise. The one-way gear disc has a total of six tooth grooves.

[0011] Preferably, a torsion spring is installed between the driving disk and the locking groove. Specifically, the torsion spring can keep the top plate at the end of the driving disk and the power arm in a downward pressure state. When the pin shaft is inserted into the sleeve and reaches the highest point, it will drive the driving disk to rotate through the top plate and the force arm. At this time, the torsion spring is in a compressed state. When the pin shaft is disengaged from the sleeve, the torsion spring releases its elastic potential energy and drives the driving disk to reset.

[0012] Preferably, there are three pins in total, and a bayonet is provided on the top edge of one of the pins. The pin with the bayonet is clearance-matched with the sleeve, and the other two pins correspond one-to-one to the positioning holes.

The entire installation process can be operated with one hand, and the installation speed is fast and efficient, which is suitable for emergency assembly needs at fire scenes. At the same time, it uses a three-in-one connector to adapt to the three sockets of the docking plate. During the hardware installation process, it is docked together with the power supply line and signal line, which greatly improves the installation speed and reduces the difficulty of operation.

The rotor 3061 is horizontally arranged inside the locking groove 303 and is rotatably connected to the locking groove 303. Three pawls a3062 are annularly and equidistantly hinged to the outside of the rotor 3061. The one-way toothed disc 3063 is sleeved on the middle section of the rotor 3061 and is fixedly connected to the rotor 3061. The spring piece 3064 is obliquely installed on the inner wall of the locking groove 303. The driving disc 3065 is installed inside the locking groove 303 and is fixedly connected to the rotor 3061. It is rotatably connected to the locking groove 303, the bottom end of the lever arm 3066 is welded to the top edge of the driving disk 3065, and the top plate 3067 is horizontally fixed to the top edge of the lever arm 3066. The ratchet 3068 is sleeved on the end of the rotor 3061 and realizes an interference fit with the rotor 3061. A pawl b3069 is installed inside the driving disk 3065, and the pawl b3069 is adapted to the ratchet 3068. The angle between the three pawls a3062 is 120 degrees.

When inserting, the pin shaft 401 is aligned with the positioning hole 302 and the sleeve 305 respectively, and the three-hole socket 402 will be aligned with the three-in-one connector 301 and inserted, thereby achieving the fixation of the monitoring device 10 and the connection of the line. It should be noted here that the new monitoring device 10 is fixed on the mounting plate 20 in advance, and then the power supply line and signal line of the monitoring device 10 are connected to the terminal 404 at the bottom of the docking plate 40 through the through hole in the middle of the mounting plate 20, and then the mounting plate 20 is embedded in the inner groove of the docking plate 40 and fixed.

During docking, the pin shaft 401 with the bayonet 4011 will be inserted into the sleeve 305, and push the top plate 3067, and cooperate with the force arm 3066 to drive the driving disk 3065 to rotate, thereby driving the rotor 3061 to rotate 60 degrees through the pawl b3069 and the ratchet 3068. At this time, the pawl a3062 will cooperate with the bayonet 4011 to lock the pin shaft 401. If the monitoring device 10 is pressed again to drive the pin shaft 401 to move, the rotor 3061 will be triggered to rotate 60 degrees again. At this time, the bayonet 4011 and the pawl a3062 are staggered to achieve unlocking.
