Description

Technical Field

[0001] This utility model relates to a tri-proof lamp with movable lamp base. Background Technology

[0002] Tri-proof lights are lighting fixtures with waterproof, dustproof, and corrosion-resistant properties. Due to their ability to withstand harsh working environments, they are widely used in parking lots, basements, mines, steel mills, and other lighting locations. They typically use specialized anti-oxidation and anti-corrosion materials and silicone sealing rings to meet the protection requirements of the fixture. The circuit control board is treated with anti-corrosion, waterproof, and anti-oxidation measures to ensure the safety and reliability of the wiring. Structurally, tri-proof lights generally include a lamp holder, lamp feet, and a lamp tube. Traditional lamp feet and holders have fixed installation positions, making adjustment inconvenient. Even slight differences in lamp tube length can prevent installation, resulting in poor versatility. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a tri-proof lamp with movable lamp feet.

[0004] To achieve the above objectives, this utility model provides a tri-proof lamp with movable lamp feet, including a lamp holder and a lamp cover. The lamp holder has lamp feet symmetrically provided at both ends along the length direction on the inner bottom surface for installing lamp tubes. The lamp feet are detachably connected to the lamp holder through a connecting positioning plate.

[0005] The connecting positioning plate is machined with a positioning groove to accommodate the lamp base. The lower part of the lamp base extends into the positioning groove, and the elastic abutment parts on both sides of the lamp base abut against the edge of the positioning groove to form support. The middle part of the connecting positioning plate is machined with an oblong hole along the length direction of the lamp holder. A corresponding integrated positioning sleeve is provided on the inner bottom surface of the lamp holder. The upper part of the positioning sleeve extends into the oblong hole. A threaded hole is machined at the center of the positioning sleeve and a locking bolt is installed. The head of the locking bolt is pressed against both sides of the oblong hole.

[0006] As a further improvement of this utility model, symmetrical limiting grooves are provided on the inner walls of both sides of the waist-shaped hole. The limiting grooves are evenly distributed along the length direction of the waist-shaped hole. A limiting strip is provided on the upper circumferential surface of the positioning sleeve along the axial direction. The limiting strip is fitted into the limiting groove.

[0007] As a further improvement of this utility model, an integral reinforcing plate is provided at the connection between the positioning sleeve and the lamp holder. The reinforcing plate is evenly distributed along the circumference of the positioning sleeve, and the upper part of the positioning sleeve abuts against the bottom surface of the connecting positioning plate.

[0008] As a further improvement of this utility model, the length of the connecting positioning plate matches the inner width of the lamp holder, a side limiting block is provided at the connection between the inner wall of the lamp holder and the bottom surface, the side limiting block provides support for both ends of the connecting positioning plate, and the height of the side limiting block matches the height of the reinforcing plate.

[0009] The beneficial effects of this utility model are as follows:

[0010] In this tri-proof lamp structure, the lamp base is installed on the connecting positioning plate and then the whole assembly is installed on the lamp holder. The connecting positioning plate has a waist-shaped hole to cooperate with the positioning sleeve on the lamp holder for positioning. The installation position of the connecting positioning plate is adjustable, which is suitable for installing lamp tubes of different lengths and has good versatility. The reinforcing plate at the bottom of the positioning sleeve and the side limiting blocks on both sides of the lamp holder together form a triangular support structure for the bottom of the connecting positioning plate, making the overall assembly structure stable.

[0017] like Figure 1-2 As shown, the tri-proof lamp with movable lamp feet according to this utility model includes a lamp holder 1 and a lamp cover 4. The lamp holder 1 has lamp feet 3 symmetrically provided at both ends along the length direction on the inner bottom surface for installing lamp tubes. The lamp feet 3 are detachably connected to the lamp holder 1 through a connecting positioning plate 2.

[0018] The connecting positioning plate 2 has a positioning groove 21 for accommodating the lamp base 3. The lower part of the lamp base 3 extends into the positioning groove 21, and the elastic abutment parts 31 on both sides of the lamp base 3 abut against the edge of the positioning groove 21 to form support. The middle part of the connecting positioning plate 2 is machined with an oblong hole 22 along the length direction of the lamp holder 1. A corresponding integrated positioning sleeve 11 is provided on the inner bottom surface of the lamp holder 1. The upper part of the positioning sleeve 11 fits into the oblong hole 22. A threaded hole 111 is machined at the center of the positioning sleeve 11 and a locking bolt 12 is installed. The head of the locking bolt 12 is pressed against both sides of the oblong hole 22. The inner walls on both sides of the oblong hole 22 are symmetrically provided with limiting grooves 23, which are evenly distributed along the length direction of the oblong hole 22 (see...). Figure 5 The positioning sleeve 11 has a limiting strip 14 axially arranged on its upper circumferential surface. The limiting strip 14 is fitted into the limiting groove 23. An integral reinforcing plate 13 is provided at the connection between the positioning sleeve 11 and the lamp holder 1. The reinforcing plates 13 are evenly distributed along the circumference of the positioning sleeve 11 (see...). Figure 4 The upper part of the positioning sleeve 11 abuts against the bottom surface of the connecting positioning plate 2. The length of the connecting positioning plate 2 matches the inner width of the lamp holder 1. A side limiting block 15 is provided at the connection between the inner wall of the lamp holder 1 and the bottom surface (see...). Figure 3 The side limiting block 15 provides support to both ends of the connecting positioning plate 2, and the height of the side limiting block 15 matches the height of the reinforcing plate 13.

[0019] In this tri-proof lamp structure, the lamp base is installed on the connecting positioning plate and then the whole assembly is installed on the lamp holder. The connecting positioning plate has a waist-shaped hole to cooperate with the positioning sleeve on the lamp holder for positioning. The installation position of the connecting positioning plate is adjustable, which is suitable for installing lamp tubes of different lengths and has good versatility. The reinforcing plate at the bottom of the positioning sleeve and the side limiting blocks on both sides of the lamp holder together form a triangular support structure for the bottom of the connecting positioning plate, making the overall assembly structure stable.

[0020] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0021] During assembly, first assemble the lamp base onto the connecting positioning plate. Insert the lower part of the lamp base into the positioning groove of the connecting positioning plate. The elastic abutment parts on both sides of the lamp base abut against the edge of the positioning groove to form support. Then assemble the connecting positioning plate with the lamp base and the lamp holder. The positioning sleeve on the inner bottom surface of the lamp holder extends from bottom to top into the waist-shaped hole of the connecting positioning plate. Select a suitable position according to the length of the lamp tube to be installed. The limiting strips on both sides of the positioning sleeve fit into the limiting grooves on both sides of the waist-shaped hole. The upper part of the positioning sleeve is flush with the waist-shaped hole. Then install the locking bolt in the middle of the positioning sleeve. The head of the locking bolt presses against both sides of the waist-shaped hole. The reinforcing plate at the bottom of the positioning sleeve and the side limiting blocks on both sides of the lamp holder together form a triangular support structure for the bottom of the connecting positioning plate.
