[0001] This utility model relates to a lamp base positioning structure for a tri-proof lamp. Background Technology

[0002] Lighting fixtures are a common and indispensable part of life, and the application of tri-proof lights is also very common. Tri-proof lights mainly consist of lamp holders, lamp feet, and lamp tubes. Traditionally, lamp feet and lamp holders are fixed by connecting bracket plates and bolts, which makes the installation and disassembly process relatively troublesome and the assembly efficiency low. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a lamp base positioning structure for a tri-proof lamp.

[0004] To achieve the above objectives, this utility model provides a lamp foot positioning structure for a tri-proof lamp, including a lamp holder. The lamp holder has symmetrical lamp feet on its inner bottom surface near both ends for mounting lamp tubes. The lamp feet are detachably connected to the positioning seats on the lamp holder via positioning plates.

[0005] The positioning plate is arranged along the width direction of the lamp holder. The lower parts of both sides of the positioning plate extend along the length direction of the lamp holder to form connecting blocks. A guide plate is provided in the middle of the outer side of the connecting block. A side limiting plate is provided above the guide plate. The guide plate and the side limiting plate surround to form an L-shaped locking groove. A protrusion is provided on the outer side of the side limiting plate.

[0006] The positioning seats are symmetrically arranged on the inner side wall of the lamp holder. On the opposite side of the positioning seats, an L-shaped locking plate and a lower baffle are provided from top to bottom. A guide groove is formed between the L-shaped locking plate and the lower baffle. A limiting protrusion is provided at the connection between the inner side of the L-shaped locking plate and the positioning seat.

[0007] After the positioning plate and the positioning seat are assembled, the L-shaped locking plate slides into the L-shaped locking groove, and the guide plate slides into the guide groove until the limiting protrusion engages with the protrusion for positioning.

[0008] As a further improvement of this utility model, the lamp base is provided with symmetrical buckles on both sides, and the positioning plate is machined with corresponding waist-shaped holes, and the buckles are engaged and positioned with the waist-shaped holes.

[0009] As a further improvement of this utility model, the thickness of the side limiting plate gradually increases from the front end to the rear end along the insertion direction, and the height of the side limiting plate gradually increases from the front end to the rear end along the insertion direction.

[0010] As a further improvement of this utility model, the protrusion is provided at the front end of the side limiting plate in the insertion direction.

[0011] As a further improvement of this utility model, the thickness of the guide plate gradually increases from the front end to the rear end along the insertion direction.

[0012] As a further improvement of this utility model, the L-shaped locking plate has an end plate on the side near the end of the lamp holder, and the lower part of the end plate is connected to the lower baffle and extends to the inner bottom surface of the lamp holder.

[0013] As a further improvement of this utility model, the ends of the L-shaped locking plate and the lower baffle away from the end plate are chamfered.

[0014] As a further improvement of this utility model, a right-angle notch is machined at the front end of the side limiting plate along the insertion direction, and the length of the right-angle notch matches the thickness of the end plate.

[0015] As a further improvement of this utility model, the cross-sectional shape of the limiting protrusion is an isosceles trapezoid.

[0016] As a further improvement of this utility model, the distance between the limiting protrusion and the inner closed end of the L-shaped locking plate is matched with the length of the protrusion.

[0017] The beneficial effects of this utility model are as follows:

[0018] This structure positions the lamp base onto the positioning plate via a snap-fit ​​mechanism. The positioning plate is then inserted into the positioning seat within the lamp holder for positioning, with corresponding protrusions and limiting protrusions providing restraint. The overall structure is simple and easy to assemble and disassemble. The positioning plate has L-shaped locking grooves and guide plates on both sides, and the positioning seat has corresponding L-shaped locking plates and guide grooves. As the L-shaped locking plates are inserted into the L-shaped locking grooves, the guide plates also slide along the guide grooves, forming a double-guided positioning structure, making the overall structure more stable. The opening width of the L-shaped locking grooves gradually decreases from the front end to the rear end along the insertion direction, which is beneficial for assembly guidance. Right-angle notches are machined at the front ends of both sides of the positioning plate along the insertion direction. After the positioning plate is positioned, these right-angle notches engage with the end plates at the ends of the positioning seats, improving the support stability between the positioning plate and the positioning seats.

Detailed Implementation

[0027] like Figure 1 As shown in the embodiment of this utility model, a lamp base positioning structure for a tri-proof lamp includes a lamp base 1. Lamp bases 4 are symmetrically provided on the inner bottom surface near both ends of the lamp base 1 for installing lamp tubes. The lamp bases 4 are detachably connected to the positioning seats 2 on the lamp base 1 through the positioning plate 3. Buckles 41 are symmetrically provided on both sides of the lamp bases 4. The positioning plate 3 is machined with corresponding waist-shaped holes 36. The buckles 41 are engaged with the waist-shaped holes 36 for positioning.

[0028] The positioning plate 3 is set along the width direction of the lamp holder 1. The lower parts of both sides of the positioning plate 3 extend along the length direction of the lamp holder 1 to form connecting blocks 31. A guide plate 32 is provided in the middle of the outer side of the connecting block 31. A side limiting plate 33 is provided above the guide plate 32. The guide plate 32 and the side limiting plate 33 enclose to form an L-shaped locking groove 35. A protrusion 34 is provided on the outer side surface of the side limiting plate 33. The thickness of the side limiting plate 33 gradually increases from the front end to the rear end along the insertion direction. The height of the side limiting plate 33 gradually increases from the front end to the rear end along the insertion direction. The protrusion 34 is located at the front end of the side limiting plate 33 in the insertion direction. The thickness of the guide plate 32 gradually increases from the front end to the rear end along the insertion direction (see...). Figure 2 , Figure 3 );

[0029] Positioning seats 2 are symmetrically arranged on the inner wall of lamp holder 1. On the opposite side of the positioning seats 2, from top to bottom, there is an L-shaped locking plate 21 and a lower baffle 23. A guide groove 24 is formed between the L-shaped locking plate 21 and the lower baffle 23. A limiting protrusion 22 is provided at the connection between the inner side of the L-shaped locking plate 21 and the positioning seat 2. The cross-sectional shape of the limiting protrusion 22 is an isosceles trapezoid. An end plate 25 is provided on the side of the L-shaped locking plate 21 near the end of the lamp holder 1. The lower part of the end plate 25 connects to the lower baffle 23 and extends to the inner bottom surface of the lamp holder 1. The ends of the L-shaped locking plate 21 and the lower baffle 23 away from the end plate 25 are chamfered. The distance between the limiting protrusion 22 and the inner closed end of the L-shaped locking plate 21 matches the length of the protrusion 34 (see...). Figure 4-7 The side limiting plate 33 has a right-angle notch 37 machined at its front end along the insertion direction. The length of the right-angle notch 37 matches the thickness of the end plate 25 (see [reference]). Figure 3 );

[0030] After the positioning plate 3 and the positioning seat 2 are assembled, the L-shaped locking plate 21 slides into the L-shaped locking groove 35, and at the same time the guide plate 32 slides into the guide groove 24 until the limiting protrusion 22 and the protrusion 34 engage and are positioned.

[0031] This structure positions the lamp base onto the positioning plate via a snap-fit ​​mechanism. The positioning plate is then inserted into the positioning seat within the lamp holder for positioning, with corresponding protrusions and limiting protrusions providing restraint. The overall structure is simple and easy to assemble and disassemble. The positioning plate has L-shaped locking grooves and guide plates on both sides, and the positioning seat has corresponding L-shaped locking plates and guide grooves. As the L-shaped locking plates are inserted into the L-shaped locking grooves, the guide plates also slide along the guide grooves, forming a double-guided positioning structure, making the overall structure more stable. The opening width of the L-shaped locking grooves gradually decreases from the front end to the rear end along the insertion direction, which is beneficial for assembly guidance. Right-angle notches are machined at the front ends of both sides of the positioning plate along the insertion direction. After the positioning plate is positioned, these right-angle notches engage with the end plates at the ends of the positioning seats, improving the support stability between the positioning plate and the positioning seats.

[0032] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0033] During assembly, align the two sides of the positioning plate with the positioning seats inside the lamp holder, with the lamp foot located on the side of the positioning plate furthest from the lamp holder end. The L-shaped locking plates on both sides of the positioning plate slide into the L-shaped locking grooves of the positioning seats, while the guide plates slide into the guide grooves until the limiting protrusion engages with the protrusion. The right-angle notch at the front end of the side limiting plate matches and engages with the end plate at the front end of the L-shaped locking plate. When the protrusion passes the position of the limiting protrusion, the limiting protrusion exerts a reverse thrust on the protrusion, pressing the protrusion against the inner wall of the L-shaped locking plate. The sidewall undergoes elastic deformation until the protrusion passes the position of the limiting protrusion and slides between the limiting protrusion and the inner end face of the L-shaped locking plate. The sidewall of the L-shaped locking plate then uses the elastic memory of the material itself to reset, restricting the protrusion between the limiting protrusion and the inner end face of the L-shaped locking plate, preventing the positioning plate from sliding back out. After the end plate at the front end of the L-shaped locking plate is inserted into the right-angle notches on both sides of the positioning plate, it also forms a horizontal and upward support force on the positioning plate as a whole, effectively preventing the positioning plate from shaking. When disassembly is required, the positioning plate can be pulled out in the opposite direction of insertion.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
