[0002] In order to effectively prevent fires, smoke alarms are installed in homes, offices or entertainment venues. Smoke alarm monitors are sensors used to monitor smoke. Once a fire hazard occurs, the electronic speaker inside will alert people in time. Smoke detectors are usually installed in a top-mounted manner by screwing the monitor to the ceiling surface so that its detection function faces downward.

[0003] According to the patent number CN220171616U, a smoke alarm monitor is disclosed, including a fixed base, the inner surfaces of both sides of the fixed base are fixedly connected with fixed grooves, one side of the two fixed grooves is fixedly connected with a connecting rod, one side of the two connecting rods is hinged with a limit block, the upper ends of one side of the two limit blocks are fixedly connected with a fixed rod, and the upper end of the fixed base is snap-connected with a lower fixing box. In the utility model, the fixed base is fixed to the surface of the ceiling or the wall by a fixing bolt, and then the snap block cooperates with the fixing groove to fix the smoke alarm monitor to the upper end of the fixed base. The snap block can facilitate the daily rapid disassembly of the smoke alarm monitor for maintenance, inspection and battery replacement, which is conducive to the disassembly and installation of the smoke alarm monitor, and also avoids frequent disassembly causing damage to the wall and ceiling and affecting the appearance. The second buzzer can prevent the smoke alarm monitor from sounding too small due to environmental noise, which will not alert the user.

[0004] Including the above patents and existing known technical means, when assembling a smoke detector, it needs to be installed on various types of walls in the building. In daily environment, the detector housing is easily damaged by furniture or ladders during construction, which in turn causes damage to the smoke detector housing, resulting in the probe being exposed and easily damaged, thereby reducing the protection effect of the smoke detector. To this end, we provide a real-time smoke concentration monitor to solve the above problems. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a real-time smoke concentration monitor.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a real-time smoke concentration monitor, comprising a mounting base and a protective cover, wherein the inner wall of the mounting base is provided with an elastic mechanism for buffering the protective cover.

[0009] In the above technical solution, preferably, a plurality of third compression springs are fixedly connected to the inner wall of the installation groove, and one end of each third compression spring is fixedly connected to the surface of the L-shaped block.

[0010] In the above technical solution, preferably, the inner wall of the bottom plate is fixedly connected with a top plate, the top plate is located below the inner top wall of the mounting base, and the movable ring slides on the bottom surface of the top plate.

[0011] In the above technical solution, preferably, an indicator plate is fixedly connected to the surface of the protective cover, and two ends of the indicator plate correspond to the two pressing blocks respectively.

[0012] In the above technical solution, preferably, two opposite indicating grooves are provided on the top plate, and the two indicating grooves correspond to the two clamping mechanisms respectively.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets an elastic mechanism. When the protective cover is hit by external objects, the movable ring squeezes each second compression spring in the bottom plate to achieve horizontal buffering of the protective cover, and at the same time drives the bottom plate to squeeze the first compression spring in the mounting base to achieve vertical buffering of the protective cover. When the protective cover is squeezed, it will also be extended into the mounting base, thereby ensuring the protectiveness of the protective cover and avoiding exposure of the monitor due to damage to the protective cover. The protective cover does not contact the monitor in the mounting base, so that the protective cover will not contact the monitor when it is squeezed and moved.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides a real-time smoke concentration monitor, comprising a mounting base 1 and a protective cover 2 , wherein the inner wall of the mounting base 1 is provided with an elastic mechanism for buffering the protective cover 2 .

[0023] The elastic mechanism includes a plurality of first compression springs 32 fixedly connected to the inner bottom wall of the mounting base 1 and a bottom plate 31 slidably arranged on the inner wall of the mounting base 1, and the top end of each first compression spring 32 is fixedly connected to the bottom surface of the bottom plate 31, so that the bottom plate 31 can have an up and down buffering effect in the mounting base 1, and the top end of the bottom plate 31 is located at the inner top wall of the mounting base 1, so that the bottom plate 31 will not separate from the outside of the mounting base 1, and can only slide up and down on the inner wall of the mounting base 1, and the inner bottom wall of the bottom plate 31 is slidably provided with an active ring 34, so that the active ring 34 can slide on the inner bottom wall of the bottom plate 31, and the middle diameter of the bottom plate 31 is smaller than the size of the active ring 34, to ensure that the active ring 34 will not fall off from the middle of the bottom plate 31, and the inner wall of the bottom plate 31 is fixedly connected to a plurality of second compression springs 33 connected to the surface of the active ring 34, and when the active ring 34 is shaken, the squeeze ring 34 will be squeezed out. The second compression springs 33 are compressed, so that the movable ring 34 can have a buffering effect at a horizontal position inside the base plate 31. Two relative clamping mechanisms are arranged between the protective cover 2 and the movable ring 34. Through the setting of the clamping mechanism, the protective cover 2 is clamped and fixed on the movable ring 34. Therefore, when the protective cover 2 on the movable ring 34 is hit by the outside world, the movable ring 34 is buffered in the horizontal direction inside the base plate 31, and at the same time drives the base plate 31 to buffer in the vertical direction inside the mounting base 1, so that the protective cover 2 has buffering protection in different directions inside the mounting base 1, and the protective cover 2 can also be extended into the mounting base 1 when squeezed, thereby ensuring the protectiveness of the protective cover 2 and avoiding exposure of the monitor due to damage to the protective cover 2, and the protective cover 2 does not contact the monitor in the mounting base 1, so that the protective cover 2 will not squeeze the monitor when it is squeezed and moved.

[0024] like Figure 2 , Figure 4 As shown, the clamping mechanism includes an L-shaped clamping groove 45 provided on the movable ring 34 and a mounting groove 42 provided at the bottom of the protective cover 2, an L-shaped clamping block 43 is elastically slidably provided in the mounting groove 42, and the bottom end of the L-shaped clamping block 43 is clamped into the L-shaped clamping groove 45, and the top end of the L-shaped clamping block 43 is fixedly connected to a pressing block 41 extending to the outside of the protective cover 2, and the inner wall of the mounting groove 42 is fixedly connected to a plurality of third compression springs 44, and one end of each third compression spring 44 is fixedly connected to the surface of the L-shaped clamping block 43, and the pressing block 41 The protruding part is smaller than the protruding part at the bottom end of the L-shaped block 43. When the pressing block 41 is squeezed by external objects, the surface of the pressing block 41 fits with the surface of the protective cover 2. At this time, the installation groove 42 will not release the clamping limit between the bottom end of the L-shaped block 43 and the L-shaped slot 45 to ensure the stability of the protective cover 2 and avoid the protective cover 2 from being separated due to external collision. Only when the pressing block 41 continues to press in the installation groove 42 can the bottom end of the L-shaped block 43 be completely separated from the L-shaped slot 45.

[0025] like Figure 4As shown, the inner wall of the bottom plate 31 is fixedly connected with the top plate 35, the top plate 35 is located below the inner top wall of the mounting base 1, and the movable ring 34 slides on the bottom surface of the top plate 35. Through the setting of the top plate 35, the movable ring 34 can be limited, so that the movable ring 34 can only slide horizontally between the bottom plate 31 and the top plate 35, avoiding the vertical movement of the movable ring 34, thereby ensuring the buffering performance of the protective cover 2 after a collision, so that the movable ring 34 can only squeeze each second compression spring 33 in the horizontal direction.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an indicator plate 51 is fixedly connected to the surface of the protective cover 2, and the two ends of the indicator plate 51 correspond to the two pressing blocks 41 respectively. Two opposite indicator grooves 52 are opened on the top plate 35, and the two indicator grooves 52 correspond to the two clamping mechanisms respectively, so that personnel can cooperate between the indicator plate 51 and the indicator groove 52. When the protective cover 2 is clamped on the movable ring 34, it is only necessary to first observe the positions of the two indicator grooves 52 to determine the positions of the two L-shaped clamping grooves 45, and then hold the protective cover 2 and observe whether the positions of the two ends of the indicator plate 51 correspond to the two indicator grooves 52, so as to ensure that the two L-shaped clamping blocks 43 are accurately inserted into the corresponding two L-shaped clamping grooves 45, thereby improving the convenience of personnel in installing the protective cover 2.

[0027] The working principle and use process of the utility model are as follows: first, observe the positions of the two indicator grooves 52 to determine the positions of the two L-shaped card slots 45, then hold the protective cover 2 and observe whether the two end positions of the indicator plate 51 correspond to the two indicator grooves 52, and then insert the two L-shaped card blocks 43 into the corresponding two L-shaped card slots 45 respectively, and the installation of the protective cover 2 can be completed. When the protective cover 2 is hit by external objects, the movable ring 34 squeezes each second compression spring 33 in the bottom plate 31 to achieve the buffering of the protective cover 2 in the horizontal direction, and at the same time drives the bottom plate 31 to squeeze the first compression spring 32 in the mounting base 1 to achieve the buffering of the protective cover 2 in the vertical direction, and the protective cover 2 will also be stretched into the mounting base 1 when squeezed, thereby ensuring the protectiveness of the protective cover 2 and avoiding the exposure of the monitor due to damage to the protective cover 2.
