[0002] Lamps are a common and indispensable part of our lives. The application of tri-proof lamps is also very common. Tri-proof lamps mainly include lamp holders, lamp feet and lamp tubes. Traditional lamp feet and lamp holders are mainly fixed by bracket plates and bolts. The installation process is more complicated and requires the preparation of bolts and tools for screwing bolts, consumption of more raw material resources, and low assembly efficiency. Summary of the invention

[0003] In view of the shortcomings existing in the above problems, the present invention provides a fixing buckle structure for the lamp foot of a triple-proof lamp tube.

[0004] To achieve the above-mentioned purpose, the present invention provides a fixing buckle structure for the lamp foot of a tri-proof lamp tube, comprising a lamp foot, wherein the lamp foot and the lamp holder are connected via a buckle structure, wherein the buckle structure and the bottom of the inner wall of the lamp holder are integrally formed, wherein the buckle structure comprises a guide block and a buckle, wherein a guide groove is machined on the guide block, wherein the buckle comprises a buckling portion, wherein a bevel is machined on the top of the buckling portion, wherein the bottom of the lamp foot matches the guide groove, and the flange at the bottom of the lamp foot is engaged with the buckling portion.

[0005] As a further improvement of the present invention, four of the buckle structures are symmetrically distributed on the lamp holder.

[0006] As a further improvement of the present invention, clamping parts are provided on the left and right side walls of the lamp foot, and the clamping parts abut against the top of the buckle.

[0007] As a further improvement of the present invention, the thickness of the upper portion of the clamping portion is less than the thickness of the side wall of the lamp pin, and the thickness of the clamping portion gradually increases from top to bottom.

[0008] As a further improvement of the present invention, an arc-shaped portion is processed on the bottom of the clamping portion.

[0009] As a further improvement of the present invention, the buckle is made of elastic material.

[0010] The beneficial effects of the present invention are:

[0011] The device is provided with a snap-on structure integrally formed with the lamp holder. The lamp pin and the lamp holder can be assembled by simply pressing the lamp pin along the guide groove and utilizing the elastic deformation of the snap-on to engage with the snap-on without the need for additional connectors. The device has a simple structure, is easy to operate, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 As shown, a fixing buckle structure of a lamp foot of a three-proof lamp tube according to the present invention comprises a lamp foot 3, the lamp foot 3 and the lamp holder 1 are connected by a buckle structure 2, the buckle structure 2 and the bottom of the inner wall of the lamp holder 1 are integrally formed, four buckle structures 2 are symmetrically distributed on the lamp holder 1, the buckle structure 2 comprises a guide block 21 and a buckle 22, a guide groove 211 is processed on the guide block 21, the buckle 22 comprises a buckling portion 221, a top of the buckling portion 221 is processed with an inclined surface 222, the buckle 22 is made of an elastic material, the bottom of the lamp foot 3 is connected to the guide groove 211 To match, the flange 32 at the bottom of the lamp pin 3 is engaged with the buckle part 221, and the clamping part 31 is set on the left and right side walls of the lamp pin 3. The clamping part 31 is against the top of the buckle 22, and the thickness of the upper part of the clamping part 31 is less than the thickness of the side wall of the lamp pin 3, which ensures that the clamping part 31 has sufficient elastic deformation. The thickness of the clamping part 31 gradually increases from top to bottom, and the arc-shaped part 311 is processed at the bottom of the clamping part 31.

[0019] The device is provided with a snap-on structure integrally formed with the lamp holder. The lamp pin and the lamp holder can be assembled by simply pressing the lamp pin along the guide groove and utilizing the elastic deformation of the snap-on to engage with the snap-on without the need for additional connectors. The device has a simple structure, is easy to operate, and improves production efficiency.

[0020] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0021] During assembly, the lamp holder is placed horizontally, and the buckle structure is symmetrically distributed on the inner bottom surface of the lamp holder. The bottom of the lamp foot is pressed downward along the guide groove. The left and right edges of the bottom of the lamp foot are against the inclined surface at the top of the buckle buckle, which exerts downward pressure on the inclined surface. The buckle is elastically deformed and tilted outwards until the flange of the lamp foot is snapped into the buckle below (see Figure 4 ), and then the buckle returns to its original position by its own resilience. During the buckle's recovery process, the inclined surface at the top of the buckle part contacts the arc-shaped part at the bottom of the clamping part, and generates corresponding pressure on the arc-shaped part. Under the action of pressure, the clamping part produces elastic deformation and tilts inwards, while the arc-shaped part keeps in contact with the inclined surface, and finally the buckle returns to its original position (see Figure 5 ), the top of the lamp pin flange contacts the bottom of the buckle fastening part, and at the same time, the arc-shaped part at the bottom of the clamping part and the inclined surface at the top of the buckle form an interaction force and tightly abut against each other to prevent the lamp pin and the buckle from disengaging, thereby forming a stable fastening structure; when disassembly is required, it is only necessary to open the buckles on both sides of the lamp pin to separate the fastening part of the buckle and the flange of the lamp pin, and then the lamp pin can be taken out.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
