[0035] In this embodiment, the lamp holder 100 comprises a housing 1, a lamp panel assembly 2, a cover plate assembly 3, and a locking assembly 4. The housing 1 encloses a cavity 11 for mounting the lamp panel assembly 2. The housing 1 also encloses a first opening 12 and a second opening 13 communicating with the cavity 11. The lamp panel assembly 2 can emit light into the first opening 12 and the second opening 13, enabling the lamp holder 100 to emit light from both sides. The cover plate assembly 3 comprises a first cover plate 31 and a second cover plate 32. The first cover plate 31 is disposed at the first opening 12. The second cover plate 32 is provided at the second opening 13 to form a closed space in the cavity 11, thereby protecting the lamp plate assembly 2 located in the cavity 11. The locking assembly 4 is detachably snapped into the housing 1 to lock at least one of the first cover plate 31 and the second cover plate 32 to the housing 1, avoiding the assembly of the cover plate assembly 3 by screws or bolts, thereby reducing the assembly steps of the cover plate assembly 3, improving the assembly efficiency of the lamp holder 100 assembly, and also facilitating the disassembly of the cover plate assembly 3, thereby facilitating the maintenance of the lamp holder 100.

[0036] In actual implementation, the locking component 4 engages with the outer shell 1 so that the first cover plate 31 covers the first opening 12, or the second cover plate 32 covers the second opening 13, or the first cover plate 31 and the second cover plate 32 respectively cover the first opening 12 and the second opening 13. The first opening 12 and the second opening 13 are located on both sides of the lamp head 100. The first opening 12 can be set away from the ground to emit ambient light, and the second opening 13 can be set towards the ground to emit working light. The first cover plate 31 can be a light-transmitting plate, and the second cover plate 32 can be a combination of a diffuser plate and a rhombus plate, or the second cover plate 32 can be a light-transmitting plate. No specific limitation is made here.

[0037] In one embodiment of the present invention, such as Figures 1 to 4 As shown, the locking assembly 4 includes a snap-fit ​​member 41, the housing 1 includes a side plate 14 and a support portion 15, the side plate 14 surrounds to form a cavity 11, the support portion 15 is connected to the side plate 14 near the first opening 12 and surrounds the side plate 14 to form a limiting groove 16, the first cover plate 31 is placed on the support portion 15, the snap-fit ​​member 41 presses against the first cover plate 31 and is limited in the limiting groove 16.

[0038] In this embodiment, the side plate 14 surrounds to form a cavity 11. The support part 15 is connected to the side plate 14 near the first opening 12 and is arranged around the first opening 12. The support part 15 and the side plate 14 surround to form a limiting groove 16. The first cover plate 31 is placed on the support plate to cover the first opening 12. The snap-fit ​​member 41 abuts against the side of the first cover plate 31 facing away from the support part 15. The snap-fit ​​member 41 is limited in the limiting groove 16 to achieve a detachable snap-fit ​​with the first cover plate 31 and the outer shell 1. The snap-fit ​​member 41 cooperates with the support part 15 so that the first cover plate 31 is detachably installed in the first opening 12.

[0039] In actual implementation, the support part 15 can be arranged at intervals around the first opening 12, or connected around the first opening 12. The support part 15 and the side plate 14 can be connected separately by bolts or welding, or the support part 15 and the side plate 14 can be integrally formed. No specific limitation is made here. The support part 15 may include a first part and a second part that are vertically connected. The first part is connected to the side plate 14 so that the second part is arranged parallel to the side plate 14. The first cover plate 31 is placed on the upper surface of the second part. The upper surface of the second part is slightly lower than the upper surface of the side plate 14 so that the height of the first cover plate 31 is not greater than the height of the side plate 14. The side plate 14 surrounds the periphery of the first cover plate 31 to reduce the wear of the first cover plate 31 and improve the aesthetics of the lamp head 100.

[0040] In one embodiment of the present invention, such as Figure 4 As shown, the snap-fit ​​member 41 includes an abutting section 411 and a snap-fit ​​section 412 connected at an angle. The abutting section 411 abuts against the side of the first cover plate 31 facing away from the support portion 15, and the snap-fit ​​section 412 is limited in the limiting groove 16.

[0041] In this embodiment, the snap-fit ​​member 41 consists of an abutment section 411 and a snap-fit ​​section 412. The lower surface of the abutment section 411 abuts against the side of the first cover plate 31 facing away from the support portion 15, thereby cooperating with the support portion 15 to make the first cover plate 31 cover the first opening 12. The snap-fit ​​section 412 is connected to the abutment section 411 and is limited in the limiting groove 16 so that the snap-fit ​​member 41 can be detachably snapped into the outer shell 1.

[0042] In actual implementation, the snap-fit ​​component 41 can be arranged at intervals and evenly around the first opening 12 corresponding to the support part 15, or it can be arranged continuously around the first opening 12. The abutment section 411 and the snap-fit ​​section 412 can be integrally formed. The side of the abutment section 411 facing away from the first cover plate 31 can be inclined to achieve the transition from the upper surface of the side plate 14 to the upper surface of the first cover plate 31, which improves the aesthetics of the lamp and saves the production cost of the snap-fit ​​component 41. The snap-fit ​​component 41 can be made of rubber or plastic. The snap-fit ​​section 412 and the limiting groove 16 can be snapped together by interference fit.

[0043] In one embodiment of the present invention, such as Figure 4 As shown, the snap-fit ​​section 412 is provided with a snap-fit ​​block 413, and the groove wall of the limiting groove 16 is provided with a corresponding groove 161. The snap-fit ​​block 413 engages with the groove 161, so that the snap-fit ​​section 412 is limited to the limiting groove 16.

[0044] In this embodiment, the snap-fit ​​segment 412 is provided with a snap-fit ​​block 413, and the groove wall of the limiting groove 16 is provided with a corresponding groove 161. The snap-fit ​​block 413 and the groove 161 cooperate to make the snap-fit ​​segment 412 more firmly and stably confined in the limiting groove 16. In actual implementation, the snap-fit ​​block 413 can be set on either side of the snap-fit ​​segment 412. Preferably, the snap-fit ​​block 413 can be set on the side of the snap-fit ​​segment 412 facing away from the first cover plate 31, and the groove 161 is set corresponding to the snap-fit ​​block 413 so that the snap-fit ​​segment 412 is subjected to force on both sides, and the force is evenly distributed, thereby improving the stability of the snap-fit ​​segment 412 confined in the limiting groove 16.

[0045] In one embodiment of the present invention, such as Figure 4 As shown, the card block 413 includes multiple card blocks, each card block 413 is provided with a corresponding groove 161, and the side of the card block 413 facing the bottom of the limiting groove 16 is inclined.

[0046] In this embodiment, multiple locking blocks 413 may be included. The multiple locking blocks 413 are spaced apart and evenly arranged on one side of the locking segment 412. Each locking block 413 is provided with a corresponding groove 161. The side of the locking block 413 facing the bottom of the limiting groove 16 is inclined, and the side closer to the groove 161 is higher and the side away from the groove 161 is lower. In this way, when the locking segment 412 is inserted from the opening of the limiting groove 16, the inclined surface can play a guiding and buffering role, so as to facilitate the locking and installation of the locking member 41 and improve the installation efficiency of the locking member 41.

[0047] In actual implementation, the groove 161 is provided on the side plate 14 or the support part 15 corresponding to the locking block 413. The depth of the groove 161 is slightly greater than the protruding length of the locking block 413 so that the locking block 413 can be fully inserted into the groove 161 and fully abut against the groove 161, so as to prevent the locking block 413 from slipping out of the groove 161.

[0048] In one embodiment of the present invention, such as Figures 2 to 4 As shown, the locking assembly 4 also includes a retaining member 42. The outer shell 1 is provided with a support 17, which surrounds the second opening 13. The second cover plate 32 is placed on the support 17. The retaining member 42 has an abutting end 421 and a retaining part 422. The outer shell 1 is provided with a buckle 18. The abutting end 421 abuts against the side of the second cover plate 32 facing away from the support 17. The retaining part 422 is engaged with the buckle 18, so that the retaining part 422 is engaged with the outer shell 1.

[0049] In this embodiment, the second cover plate 32 is placed on the support 17 provided on the outer shell 1, thereby covering the second opening 13. The retaining part 422 is engaged with the outer shell 1 by the buckle 18, thereby making the retaining part 42 detachably connected to the outer shell 1. The abutting section 411 of the retaining part 42 abuts against the side of the second cover plate 32 facing away from the support 17, thereby cooperating with the support 17 so that the second cover plate 32 covers the second opening 13. This avoids connecting the second cover plate 32 and the outer shell 1 by screws or bolts, simplifies the assembly steps of the second cover plate 32 to the outer shell 1, and improves the assembly efficiency of the second cover plate 32.

[0050] In actual implementation, the support platform 17 can be integrally formed with the outer shell 1. The support platform 17 is perpendicular to the outer shell 1 and extends toward the second opening 13. The support platform 17 and the retaining member 42 can be arranged at intervals and evenly around the second opening 13, or continuously arranged along the second opening 13. The retaining member 42 can be arranged at intervals around the second opening 13 or at intervals around the second opening 13. The retaining part 422 can be hook-shaped or configured as a hook or other structure that engages with the buckle 18. No specific limitation is made here.

[0051] In one embodiment of the present invention, such as Figure 4 As shown, the buckle 18 includes two buckles; the two buckles 18 are spaced apart on the outer shell 1, and each buckle 18 is provided with a corresponding holding part 422; and / or, the two buckles 18 are disposed opposite to each other on the outer shell 1.

[0052] In this embodiment, the latches 18 may include two, each latch 18 having a corresponding holding part 422, thereby distributing the pressure on the latches 18, reducing the wear rate of the holding part 422 and the latches 18, and also enabling at least two points on the latching member 41 to engage with the latches 18, improving the stability of the engagement between the holding part 422 and the latches 18. The two latches 18 are arranged opposite to each other, with the holding part 422 corresponding to the latches 18, to balance the pressure of the latches 18 on the holding part 422, preventing uneven force on the holding member 42 and causing it to move within the cavity 11.

[0053] In actual implementation, there may be multiple latches 18, with one latching part 422 corresponding to one latch 18. No specific limitation is made here. The side of the latching part 422 facing the latch 18 is provided with a guide slope. Correspondingly, the side of the latch 18 facing the latching part 422 may also be provided with a guide slope, so as to facilitate the insertion of the latching part 422 into the latch 18, reduce the assembly difficulty of the latching part 42, and improve the assembly efficiency of the latching part 42.

[0054] In one embodiment of the present invention, such as Figure 4 As shown, the abutment end 421 is hook-shaped, and the outer side of the abutment end 421 abuts against the second cover plate 32.

[0055] In this embodiment, the abutting end 421 of the retaining member 42 is hook-shaped, so that the abutting end 421 has a certain elasticity to elastically abut against the second cover plate 32, thereby tightly confining the second cover plate 32 between the support platform 17 and the abutting end 421, preventing the second cover plate 32 from sliding on the support platform 17 and affecting the stability of the second cover plate 32.

[0056] In actual implementation, the abutting end 421 is provided at the end of the retaining member 42, and the retaining part 422 is provided on one side of the retaining member 42. The retaining part 422 cooperates with the buckle 18 of the outer shell 1 to restrict the displacement of the retaining part 422 in the axial direction, so that the abutting end 421 always presses against the second cover plate 32 in the axial direction.
