[0039] refer to Figure 4 As shown, the early warning trigger circuit also includes a power module and an alarm module, and the power module, the alarm module, the metal swing body and the metal frame form a series circuit through wires.

[0040] Specifically, the alarm module is a sound and / or light alarm; and the housing is provided with a window for exposing the alarm module.

[0041] In this embodiment, the adsorption device includes a lining plate, a magnetic plate is embedded in the front end surface of the lining plate, and the end surface of the lining plate is fixedly connected to the shell. The magnetic plate is made of a magnetic material with strong magnetism, and the shell is made of a metal material to shield magnetic field interference.

[0042] A sealing and filling method adopts the sealing and filling tool of the present invention. When the filling pipe is tilted, the tilt warning device sends out an alarm; when the filling pipe is adjusted to a vertical state, the tilt warning device stops the alarm.

[0043] The filling tube 2 is inserted into the sleeve 1 and extends to the outside of the sleeve 1. A lining plate 3 is provided on the top of the right side of the filling tube 2. A magnetic plate 4 is embedded on the left side of the lining plate 3. The outer surface of the magnetic plate 4 is magnetically attracted to the connection between the filling tube 2 and the right side of the lining plate 3. A shell 5 is fixedly connected to the inner cavity of the shell 5. A partition 6 is fixedly connected to the top of the partition 6. A battery 7 is fixedly connected to the top of the partition 6 by screws. A metal frame 8 is fixedly installed on the bottom of the inner cavity of the shell 5. A connecting rope 9 is fixedly connected to the bottom of the partition 6. A metal oscillator 10 is fixedly connected to the bottom of the connecting rope 9. The metal oscillator 10 is located in the inner cavity of the metal frame 8. An alarm module 11 is embedded on the top of the shell 5.

[0044] By arranging the lining plate 3, the magnetic plate 4, the shell 5, the partition plate 6, the battery 7, the metal frame 8, the connecting rope 9, the metal swing body 10 and the alarm module 11, it is possible to give an early warning alarm when the filling tube 2 is tilted. At the same time, the lining plate 3 and the magnetic plate 4 are arranged to facilitate the magnetic connection between the shell 5 and the filling tube 2. By arranging the above structure, the filling tool has the advantage of having an anti-tilt early warning function when in use, thereby solving the problem that the original filling tool does not have an anti-tilt early warning function when in use, thereby avoiding affecting the filling effect.

[0045] A screw rod 12 is threadedly connected to the bottom of the right side of the lining plate 3, and the left end of the screw rod 12 passes through the lining plate 3 and is rotatably connected to a push plate 13 through a bearing. The outer surface of the push plate 13 fits tightly against the connection of the filling tube 2.

[0047] A protective cover 16 used in conjunction with the alarm module 11 is fixedly connected to the top of the shell 5, and an inspection plate 17 is fixedly connected to the front of the shell 5 by screws. By providing the protective cover 16, the alarm module 11 can be protected.

[0048] By setting up the inspection plate 17, it is convenient for the staff to replace and maintain the parts in the inner cavity of the shell 5; the electrical output end of the battery 7 is electrically connected to the electrical input end of the alarm module 11 through a wire, the power supply voltage of the battery 7 is 5V, and the wire is connected in series with the metal frame 8, the metal swing body 10 and the alarm module 11.

[0049] When in use, the staff uses the magnetic plate 4 to magnetically attract the device to the top of one side of the filling tube 2. When the filling tube 2 is inserted into the inner cavity of the sleeve 1 and tilted, the metal swing body 10 will remain vertically downward under the action of gravity, and the metal frame 8 will tilt under the drive of the shell 5, so that the metal swing body 10 contacts the metal frame 8, so that the battery 7 energizes the alarm module 11, so that the alarm module 11 becomes brighter and emits light, thereby achieving an early warning alarm effect for the construction personnel.

[0050] Then, the construction personnel calibrate the filling tube 2 so that the shell 5 drives the metal frame 8 and the metal swing body 10 to maintain a vertical state, so that the battery 7 cuts off the power to the alarm module 11, thereby canceling the early warning alarm for the construction personnel.

[0051] When the filling tube 2 is completely inserted into the inner cavity of the sleeve 1 and the device needs to be disassembled, the staff holds the device with one hand and turns the handle 14 with the other hand, so that the handle 14 drives the screw 12 to rotate on the inner surface thread of the lining 3. At the same time, the screw 12 drives the push plate 13 to move, so that the push plate 13 contacts the filling tube 2. At the same time, the lining 3 drives the magnetic plate 4 away from the filling tube 2, thereby completing the disassembly of the device. The device is simple to operate and is convenient for use as a tilt warning, thereby avoiding affecting the filling effect.

[0052] This embodiment can give an early warning alarm when the filling tube is tilted. At the same time, the lining plate and the magnetic plate are arranged to facilitate the magnetic connection between the shell and the filling tube. By arranging the above structure, the filling tool has the advantage of having an anti-tilt early warning function when in use, thereby solving the problem that the original filling tool does not have an anti-tilt early warning function when in use, thereby avoiding affecting the filling effect.

[0054] Example 2

[0055] The tilt warning device of the present invention can be used not only on sealing and filling tools, but also on various carriers that need tilt warning. When the carrier material is a non-metallic material, only the structure of the adsorption device needs to be changed.

[0064] Specifically, the alarm module is a sound and / or light alarm; and the housing is provided with a window for exposing the alarm module.

[0065] During use, the staff uses a suction cup to attach the tilt warning device to the carrier. When the carrier tilts, the metal swing body will remain vertically downward under the action of gravity, and the metal frame will tilt under the drive of the shell, so that the metal swing body contacts the metal frame, and the battery powers on the alarm module, causing the alarm module to emit a buzzing alarm.

[0066] When the device needs to be disassembled, the staff holds the device with one hand and turns the handle with the other hand, so that the handle drives the screw to rotate on the inner surface thread of the liner. At the same time, the screw drives the push plate to move, so that the push plate contacts the filling tube. At the same time, the liner drives the suction cup away from the carrier, thereby completing the disassembly of the device. The device is easy to operate.

[0076] Specifically, the alarm module is a sound and / or light alarm; and the housing is provided with a window for exposing the alarm module.

[0077] Specifically, holes are opened on both sides of the lining plate, and the two ends of the elastic band pass through the holes on both sides of the lining plate respectively, thereby forming a space for wrapping the carrier between the lining plate, and then tightening the elastic band to stick the tilt warning device tightly to the carrier, and then wrap the shell with the elastic band in reverse, and finally fix the elastic band by tying a knot, and can also be fixed by using the viscosity of the self-adhesive elastic band.
