s5, when a large number of articles are placed above the device by a user, great pressure is caused to the device, the supporting plate 5 moves downwards, the supporting plate 5 pushes down to drive the supporting frame 4 to move downwards, the shrinkage of the supporting frame 4 is reduced by the shrinkage of the buffer spring 3 in the process of pushing down, the pressure above is reduced, meanwhile, the pressure above is sensed by the pressure sensor 101, then the detected information is transmitted to the alarm 103 through the sensing wire 102, when the pressure above is larger than a preset value, the alarm 103 can give out alarm sound, the alarm sound reminds the user that the weight on the device is overweight, the equipment is easy to damage, and weight reduction is needed.
Working principle: when a worker installs a plate, the worker firstly drills holes at a position to be installed, then installs the expansion bolt 201 in the drilled hole, then the worker installs the base of the installation plate 1 at the position to be installed, the installation screw 2 penetrates through the inner side of the installation plate 1, then the bottom end of the installation screw 2 is installed on the inner side of the expansion bolt 201 through threads, in the process of entering the installation screw 2, the installation screw 2 extrudes the outer part of the expansion bolt 201 in the entering process because the inner diameter of the installation screw 2 slowly reduces, the outer part of the expansion bolt 201 expands outwards while the anti-skid pad 202 expands outwards, the friction force of the expansion bolt 201 is increased, the stability of the expansion bolt 201 is ensured, the installation screw 2 is convenient to fix the installation plate 1, after the installation of the installation plate 1 is completed, the buffer spring 3 is arranged on the mounting plate 1 through the second connecting plate 302 by a user, the stability of the buffer spring 3 is ensured, the buffer spring 3 is fixed on the supporting frame 4 through the first connecting plate 301, the stability of the supporting frame 4 is ensured, the supporting frame 4 is fixed on the limit frame 402, the limit frame 402 is used for limiting the inner supporting plate 5, the device is convenient for the user to assemble the device, the limit piece 502 on the supporting plate 5 is embedded and arranged on the inner side of the limit hole 401 while the supporting plate 5 is arranged on the inner side of the limit frame 402, the limit piece 502 on the inner side is limited by the limit hole 401, the offset of the limit piece 502 is avoided, the user can assemble the broken device conveniently, after the installation of the supporting plate 5 is completed, the user places the heat-insulating plate 6 on the inner side of the supporting plate 5, the embedded piece 501 on the supporting plate 5 is embedded with the embedded groove 601, the heat-insulating plate 6 is limited through the embedded piece 501, ensuring the stability of the heat insulation board 6, then the user will make the return spring 503 support the clamping piece 504, placing the dampproof board 7 at the inner side of the supporting board 5, arranging the second reinforcing ribs 701 and the first reinforcing ribs 602 on the dampproof board 7 in parallel two by two, then the user clamps the clamping plate 804 on the waterproof board 8 at the outer side of the supporting board 5, the clamping groove 801 is jogged with the clamping piece 504, fixing the clamping plate 804 through the clamping piece 504, ensuring the stability of the waterproof board 8, installing the waterproof board 8 at the outermost side, separating the inner board from the outside, ensuring that the inner board is not affected by water, and going bad, after the waterproof board 8 is installed, the user penetrates the connecting screw 803 at the inner side of the waterproof board 8, and at the same time, the connecting screw 803 penetrates the inner side of the heat insulation board 6 and the dampproof board 7, then rotating the connecting screw 803 so that one end of the connecting screw 803 is installed at the inner side of the internal thread connecting hole 505, through the connection of connecting screw 803, with all panel together, avoid inside long-time use to take place not hard up condition, when user places a large amount of articles in the top of device, can cause very big pressure to the device, make backup pad 5 downwardly moving, backup pad 5 pushes down and drives braced frame 4 downwardly moving, braced frame 4 pushes down the in-process, by buffer spring 3's shrink, slow down the pressure of top, simultaneously respond to the pressure of top by pressure sensor 101, then transmit the information that detects to alarm 103 through sensing wire 102, the pressure numerical value of user's advance equipment, when being greater than the numerical value of preset in the top pressure, alarm 103 can send out alarm sound, alarm sound reminds the weight on the user's device overweight, cause the damage to equipment easily, need subtract heavy.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
