Technical Field

[0001] The utility model relates to the technical field of three-proof lamps, and more specifically, to a clamping structure and a three-proof lamp. Background Art

[0002] A three-proof lamp is a device used for providing illumination. Currently, the three-proof lamps on the market mainly include a base, a lamp body, and a lamp cover. The lamp body is fixed in the middle of the lower end face of the base, and the lamp cover is fixed on the lower end of the base. When the lamp body emits light, the light emitted by the lamp body can pass through the lamp cover to play a role in illumination. However, in the structure of the three-proof lamps on the market currently, the lamp cover and the base are fixed by means of gluing or bolt fastening. Therefore, when the three-proof lamp needs to be repaired, there is a disadvantage that it is inconvenient to disassemble the lamp cover from the base, which will cause inconvenience to the maintenance personnel. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a clamping structure and a three-proof lamp, which have the advantages of being convenient to lock or unlock the lamp cover and the base, so as to facilitate the assembly of the lamp cover and the base and the maintenance of the three-proof lamp.

[0004] The utility model provides a clamping structure, which includes a base and a lamp cover. The upper end of the lamp cover is fitted with the lower end of the base; at least one buckle assembly is connected to the outer walls on the front and rear sides of the base; each buckle assembly has a locking end, and when the buckle assembly is in a locked state, the locking end is used to abut against the bottom surface of the outer edge of the lamp cover to press the lamp cover on the base.

[0006] In a possible implementation manner, at least two buckle assemblies are connected to the outer walls on the front and rear sides of the base, and the two buckle assemblies on the front side of the base and the two buckle assemblies on the rear side of the base are respectively located at the two ends in the length direction of the base; by arranging at least two buckle assemblies on the outer walls on the front and rear sides of the base, and since the two buckle assemblies on the front side of the base and the two buckle assemblies on the rear side of the base are respectively located at the two ends in the length direction of the base, the lamp cover can be reliably locked with the base, and the stability and reliability after the lamp cover and the base are locked can be improved.

[0007] In a possible implementation, each buckle assembly includes a rotating connecting member and a buckle body; an opening groove is provided on the outer wall of the base at the position where each buckle assembly is located. One end of each rotating connecting member is rotatably connected to the bottom of the opening groove at the corresponding position, and the other end of each rotating connecting member is rotatably connected to the upper end of the corresponding buckle body. The lower end of each buckle body forms the locking end of the buckle assembly; when the upper ends of the rotating connecting member and the buckle body rotate upward and are embedded into the opening groove, the locking end of the buckle assembly is used to abut against the bottom surface of the outer edge of the lamp shade to press the lamp shade against the base; after adopting this kind of buckle assembly, when driving the upper ends of the rotating connecting member and the buckle body to rotate upward and be embedded into the opening groove, the locking end of the buckle assembly can abut against the bottom surface of the outer edge of the lamp shade to press the lamp shade against the base, so that the lamp shade can be reliably locked with the base, and has the advantages of high stability and high reliability after the lamp shade is locked with the base.

[0008] In a possible implementation, the lower end of each buckle body curls inward to form a hook portion, and a hook groove corresponding to the hook portion on each buckle body is provided at the bottom of the outer edge of the lamp shade. When the upper ends of the rotating connecting member and the buckle body rotate upward and are embedded into the opening groove, the hook portion is used to hook into the hook groove and abut against the inner top of the hook groove to press the lamp shade against the base; after adopting this structure, when driving the upper ends of the rotating connecting member and the buckle body to rotate upward and be embedded into the opening groove, the hook portion can hook into the hook groove and abut against the inner top of the hook groove to press the lamp shade against the base. Thus, under the cooperation of the hook portion and the hook groove, the limiting effect between the buckle assembly and the lamp shade can be realized, that is, the stability and reliability after the lamp shade is locked with the base can be further improved.

[0009] In a possible implementation, a first rotating shaft is provided at one end of the rotating connecting member, and two symmetrically arranged embedding grooves are provided on the inner bottom of the opening groove.
