Description

Technical Field

[0001] The utility model relates to the technical field of underground lamps, in particular to an underground lamp for fire fighting. Background Art

[0002] Firefighting is the general term for eliminating hidden dangers and preventing disasters, that is, preventing and solving man-made, natural and accidental disasters encountered by people in the process of life, work and study. Of course, the narrow meaning in the early stage of people's understanding is: extinguishing fires. The underground lamp for firefighting is an indicating device used to indicate safe passages. The existing underground lamp for firefighting is fixed by screws. This fixing method is not only inefficient in installation, but also troublesome in later maintenance and replacement. In order to solve the above problems, the patent document with announcement number CN215298759U proposes an underground lamp for firefighting, which includes a base, an underground lamp installed in the base, a limit strip circumferentially installed on the inner wall of the bottom of the base, and two handles rotatably matched at the upper end of the underground lamp, so that it is easy to pull the two handles to drive the underground lamp to slide along the inclined surface of the inner wall of the limit notch, and then quickly pull out the underground lamp, which is convenient for repairing and replacing the underground lamp. However, there is no locking structure when it is used, which is easy to be pulled out by non-maintenance personnel, and thus taken away and damaged. Utility Model Content

[0003] The utility model mainly provides a ground-buried lamp for fire fighting, which solves the problem that the prior art has no locking structure and is easily pulled out by non-maintenance personnel, thereby being damaged.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A fire-fighting underground lamp comprises a controller with a signal receiving function, a motor, a bottom shell and an underground lamp; the controller and the motor are both installed in the bottom shell, and the motor is electrically connected to the controller, a connecting stud is installed at the output end of the motor, and a connecting screw hole matching the connecting stud is provided on the underground lamp; a guide rod is also installed in the bottom shell, and a guide hole matching the guide rod is provided on the underground lamp. The controller can adopt the existing technology, as long as it can receive the corresponding signal to realize the functions of controlling the forward rotation, stop and reverse rotation of the motor. During installation, align the connecting screw on the underground lamp with the connecting stud, align the guide hole with the guide rod, send a forward rotation signal to the controller, and control the motor through the controller, thereby driving the underground lamp to descend, and stop when reaching a certain height; conversely, send a reverse rotation signal to the controller, thereby controlling the motor to reverse and raise the underground lamp, and directly remove the underground lamp when the connecting screw exits the connecting screw hole. The structure of the present application can not only realize convenient disassembly and assembly of the underground lamp for maintenance and replacement, but also can prevent the underground lamp from being taken away and damaged by non-maintenance personnel by means of matching and locking the connecting studs and connecting screws.

[0006] Furthermore, at least two guide rods are included, and the two guide rods and the connecting studs are distributed in a triangle. In this way, the overall structure is more stable.

[0007] Furthermore, a plurality of springs for supporting the bottom of the underground lamp are installed on the bottom shell. With this structure, after the connecting stud is separated from the connecting screw hole, the underground lamp can be further raised, so that it is convenient for maintenance personnel to remove it.

[0008] Furthermore, the top height of the guide rod is higher than the top height of the connecting stud. With this structure, the stability of the underground lamp can be maintained even after the connecting stud is separated from the connecting screw hole.

[0009] Furthermore, the outer ends of the connecting screw hole and the guide hole are both chamfered. With this structure, it is convenient to connect the stud and the guide rod.

[0010] Beneficial effects: The structure of the present application can not only facilitate the disassembly and assembly of underground lamps for repair and replacement, but also can prevent the underground lamps from being taken away and damaged by non-maintenance personnel by means of the connecting studs and connecting screws for locking.

[0014] The technical solution of a fire-fighting ground-buried lamp involved in the utility model will be further described in detail below in combination with embodiments.

[0015] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] like Figure 1 , Figure 2As shown, a fire-fighting underground lamp 4 of this embodiment includes a controller 1 with a signal receiving function, a motor 2, a bottom shell 3 and an underground lamp 4; the controller 1 and the motor 2 are both installed in the bottom shell 3, and the motor 2 is electrically connected to the controller 1, a connecting stud 5 is installed at the output end of the motor 2, and a connecting screw hole matching the connecting stud 5 is provided on the underground lamp 4; a guide rod 6 is also installed in the bottom shell 3, and a guide hole matching the guide rod 6 is provided on the underground lamp 4. At least two guide rods 6 are included, and the two guide rods 6 and the connecting stud 5 are distributed in a triangle. A plurality of springs 7 for supporting the bottom of the underground lamp 4 are installed on the bottom shell 3. The top height of the guide rod 6 is higher than the top height of the connecting stud. The outer ends of the connecting screw hole and the guide hole are both chamfered. During installation, align the connecting screw on the underground lamp 4 with the connecting stud 5, align the guide hole with the guide rod 6, send a forward signal to the controller 1, and control the motor 2 through the controller 1, thereby driving the underground lamp 4 to descend, and stop when it reaches a certain height; on the contrary, send a reverse signal to the controller 1, thereby controlling the motor 2 to reverse and raise the underground lamp 4, and directly remove the underground lamp 4 after the connecting screw exits the connecting screw hole. The structure of the present application can not only realize the convenient disassembly and assembly of the underground lamp 4 for maintenance and replacement, but also can prevent the underground lamp 4 from being taken away and damaged by non-maintenance personnel by matching and locking the connecting stud 5 and the connecting screw.
