Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 6 As shown in one example, this solution provides a power supply box mounting structure for a lamp, including a housing 1 and a power supply component 2 disposed on the housing 1, and the power supply component 2 has a grounding wire 21;

[0031] Reference Figure 1-3 As shown, the power supply box mounting structure also includes a fixing bracket 3 and a first fastener 4; the housing 1 is conductive; both ends of the fixing bracket 3 are connected to the housing 1 to clamp the power supply assembly 2 onto the housing 1;

[0032] At least one end of the fixed bracket 3 is detachably connected to the housing 1 via a first fastener 4. The first fastener 4 is connected to the grounding wire 21 of the power supply assembly 2, so that an electrical connection is formed between the grounding wire 21 of the power supply assembly 2 and the housing 1.

[0033] In addition, a conductive connector 5 is connected to the housing 1, and the first end of the fixing bracket 3 is detachably locked to the connector 5 by a first fastener 4.

[0034] In this embodiment, the power supply component 2 is detachably clamped onto the housing 1 of the LED lamp by the connector 5 and the fixing bracket 3, giving the LED lamp the advantage of easy disassembly and replacement of the power supply component 2. Simultaneously, the first bent portion 31 of the fixing bracket 3 is connected to the second bent portion 51 of the connector 5 by the first fastener 4. Simply twisting the first fastener 4 allows for the connection and separation between the fixing bracket 3 and the connector 5, thereby enabling the disassembly and installation of the power supply component 2 and the housing 1 of the LED lamp. The power box mounting structure of this embodiment is simple, easy to operate, low in cost, and offers improved performance. This power box mounting structure requires no tools, is completed manually, and is simple to operate.

[0035] Reference Figure 1-5 As shown, the specific structure of the power supply box mounting structure is as follows:

[0036] A conductive connector 5 is connected to the housing 1, and the first end of the fixing bracket 3 is detachably locked to the connector 5 by a first fastener 4; the second end of the fixing bracket 3 and the connector 5 are respectively connected to the two sides of the housing 1 along its length direction; the connector 5 has a second bent portion 51 extending toward the inside of the housing 1, and the first end of the fixing bracket 3 has a first bent portion 31, which is detachably locked to the second bent portion 51 by the first fastener 4.

[0037] Meanwhile, the second end of the fixed bracket 3 and the connector 5 are respectively connected to both sides of the housing 1 along its length direction by the second fastener 6. Both sides of the housing 1 along its length direction are provided with connecting grooves 11. The fixed bracket 3 and the connector 5 are connected to the connecting grooves 11 provided in the housing 1 by the second fastener 6.

[0038] like Figure 4As shown, the connecting member 5 is L-shaped. One end of the connecting member 5 is provided with a through hole 32. Connecting grooves 11 are provided on both sides of the housing 1 along its length direction. The second fastener 6 inserted into the through hole 32 is connected to the connecting groove 11, so that the connecting member 5 is connected to one side of the housing 1 along its length direction through the second fastener 6. One end of the connecting member 5 away from the housing 1 is provided with a second bending portion 51, and the second bending portion 51 extends towards the inner side of the housing 1. A plurality of connecting holes 52 for connecting with the first fastener 4 are provided on the second bending portion 51, and the connecting holes 52 are arranged at equal intervals along the length direction of the housing 1.

[0039] As Figure 5 shown, the fixing bracket 3 is "U"-shaped. A through hole 32 is provided at the second end of the fixing bracket 3. Connecting grooves 11 are provided on both sides of the housing 1 along its length direction. The second fastener 6 inserted into the through hole 32 is connected to the connecting groove 11, so that the second end of the fixing bracket 3 is connected to the other side of the housing 1 along its length direction through the second fastener 6. A first bending portion 31 is provided at the first end of the fixing bracket 3, and an opening 34 is provided on the first bending portion 31. The first fastener 4 is inserted into the opening 34.

[0040] In addition, anti-slip lines for preventing the power supply component 2 from slipping sideways are provided on the concave side of the fixing bracket 3.

[0041] It should be noted that in this embodiment, the second fastener 6 is a self-tapping screw, a common screw or a rotary buckle. Both the fixing bracket 3 and the connecting member 5 are connected to the housing 1 through the second fastener 6. As long as the connection relationship remains unchanged, the second fastener 6 can adopt any connection mechanism and can achieve the same effect, which will not be described in detail here.

[0042] Referring to Figure 1-3 shown, the connecting hole 52 is connected to the first fastener 4, so that the first bending portion 31 of the fixing bracket 3 is connected to the second bending portion 51 provided on the connecting member 5 through the first fastener 4, thereby clamping and connecting the power supply component 2 to the housing 1 of the LED lamp through the fixing bracket 3. Just by twisting the first fastener 4, the connection and separation between the fixing bracket 3 and the connecting member 5 can be completed, thereby realizing the fixing and disassembly of the power supply component 2. In addition, through the settings of the first bending portion 31 and the second bending portion 51, the power supply box installation structure will not expose its structural members outside the LED lamp, thus increasing the volume of the LED lamp.

[0043] It should be noted that in this embodiment, the first fastener 4 is a hand-tightening screw, and the hand-tightening screw has a hand-held portion for hand operation. The operator loosens and tightens the hand-tightening screw by clamping the hand-held portion of the hand-tightening screw, thereby realizing the detachable locking of the fixing bracket 3 to the connecting member 5 through the first fastener 4.

[0044] Among them, the hand-tightening screws can be knurled head hand-tightening screws, wing screws, knob screws, T-handle screws, hand-tightening eye screws, etc.; as long as the connection relationship between the fixed bracket 3 and the connector 5 remains unchanged, and can be tightened and loosened manually, the first fastener 4 can use any connection mechanism to achieve the same effect, which will not be described in detail here.

[0045] Alternatively, the first fastener 4 can be an internal hex screw, a regular screw, a rotating clip, etc., and tools can be used to connect the fixing bracket 3 and the connector 5 together.

[0046] The technical solution provided by this utility model is that the housing 1 and the power component 2 are simultaneously fixed by a fixed bracket 3 and a first fastener 4, and the inner concave side of the fixed bracket 3 is provided with anti-slip texture, which increases the friction between the power component 2 and the fixed bracket 3, thereby making the installation of the power component 2 more secure, and thus making the power box installation structure have the characteristics of simple structure and firm snap-fit.

[0047] In addition, the power box mounting structure reduces the use of fasteners, thereby improving device production efficiency and reducing production costs. Without adding new structures, the housing 1 and the power assembly 2 are fixedly connected together by the fixing bracket 3, giving customers a perfect visual experience and a perfect experience in terms of lighting installation and subsequent use environment.

[0048] Reference Figure 1-3 As shown, the grounding wire 21 of the power supply assembly 2 extends to the connection between the fixed bracket 3 and the connector 5. The end of the grounding wire 21 away from the power supply assembly 2 is connected to a terminal 22. The first fastener 4 is connected to the grounding wire 21 through the terminal 22. The terminal 22 is located between the first fastener 4 and the first bent portion 31 or between the first bent portion 31 and the second bent portion 51. At the same time, a serrated washer 23 is provided between the first bent portion 31 or the second bent portion 51 and the terminal 22.

[0049] By simply twisting the first fastener 4, the connection and separation between the first bent part 31 of the fixing bracket 3 and the second bent part 51 of the connector 5 can be completed, thereby realizing the fixing and disassembly of the power supply component 2; at the same time, the electrical connection between the grounding wire 21 of the power supply component 2 and the housing 1 is completed, thereby completing the grounding operation of the power supply component 2.

[0050] In addition, in this embodiment, the housing 1 is a one-piece molded shell, and the housing 1 is a metal shell made of metal material (such as an aluminum shell), or the housing 1 is a plastic shell with conductive lines; by utilizing the conductive function of the housing 1, and through the cooperation of the grounding wire 21 with the housing 1, the power supply component 2 can be grounded; at the same time, the lamp is connected to the installation position through the connecting bracket (such as the installation position is a metal mounting bracket, and the connecting bracket is made of metal material); therefore, the power supply component 2 can complete the grounding operation without the need for additional leads.

[0051] It should be noted that a serrated washer 23 is provided between the first bend 31 or the second bend 51 and the terminal 22. The serrated washer 23 solves the problem of poor contact between the terminal 22 and the second bend 51. At the same time, since the subway panel light is in a vibrating environment, the serrated washer 23 acts as a spring washer to prevent the first fastener 4 from loosening.

[0052] Example 2

[0053] See Figure 1-4 as well as Figure 6 As shown, this utility model provides a second embodiment of a power box mounting structure. The power box mounting structure includes a housing 1, a power component 2 disposed on the housing 1, a fixing bracket 3, and a first fastener 4. Both ends of the fixing bracket 3 are connected to the housing 1 to clamp the power component 2 onto the housing 1. The housing 1 is conductive, and the power component 2 has a grounding wire 21.

[0054] At least one end of the fixed bracket 3 is detachably connected to the housing 1 by a first fastener 4, which is connected to the grounding wire 21 of the power supply assembly 2, so that an electrical connection is formed between the grounding wire 21 of the power supply assembly 2 and the housing 1.

[0055] The second embodiment is largely the same as the first embodiment, except that the second embodiment differs from the first embodiment in that, referring to... Figure 6 As shown, the second section of the fixed bracket 3 is provided with a hook part 33, and the hook part 33 is located on the left and right sides of the through hole 32. The hook part 33 is inserted into the connecting groove 11.

[0056] Alternatively, the hook portion 33 can also be provided on the connector 5.

[0057] In this embodiment, the hook portion 33 of the fixing bracket 3 adopts an L-shaped structure design and is inserted into the connecting groove 11 of the housing 1. A second fastener 6 is provided between the two hook portions 33. The second fastener 6 is connected to the connecting groove 11 to fix the hook portion 33 in the connecting groove 11. The setting of the hook portion 33 greatly increases the connection firmness between the fixing bracket 3 and the housing 1. At the same time, by loosening the second fastener 6, the hook portion 33 can slide along the connecting groove 11, so that the power box mounting structure can slide along the length direction of the connecting groove 11, thereby achieving the purpose of flexibly adjusting the installation position.

[0058] Example 3

[0059] See Figure 1-4 as well as Figure 7 As shown, this utility model provides a third embodiment of a power box mounting structure. The power box mounting structure includes a housing 1, a power component 2 disposed on the housing 1, a fixing bracket 3, and a first fastener 4. Both ends of the fixing bracket 3 are connected to the housing 1 to clamp the power component 2 onto the housing 1. The housing 1 is conductive, and the power component 2 has a grounding wire 21.

[0060] The third embodiment is largely the same as the first embodiment, except that the third embodiment differs from the first embodiment in that:

[0061] Reference Figure 7 As shown, the fixing bracket 3 is in the shape of an "n" and its two ends are directly connected to both sides of the housing 1 along its length to directly clamp the power supply component 2 onto the housing 1; wherein, the fixing bracket 3 and the housing 1 cooperate to form an installation space for installing the power supply component 2.

[0062] The first end of the fixed bracket 3 has an opening 34, and a first fastener 4 is inserted through the opening 34. The first end of the fixed bracket 3 is connected to the connecting groove 11 on one side of the housing 1 through the first fastener 4. The first end of the fixed bracket 3 has a through hole 32, and a second fastener 6 is inserted through the through hole 32. The second end of the fixed bracket 3 is connected to the connecting groove 11 on the other side of the housing 1 through the second fastener 6. The first fastener 4 is connected to the grounding wire 21 of the power supply component 2 so that an electrical connection is formed between the grounding wire 21 of the power supply component 2 and the housing 1.

[0063] It should be noted that since both the opening 34 and the through hole 32 are oblong holes, the position of the first fastener 4 in the opening 34 can be adjusted, thereby adjusting the size of the installation space, and then the power assembly 2 is tightly clamped to the housing 1 by the fixing bracket 3; at the same time, the concave side of the fixing bracket 3 is provided with anti-slip texture to prevent the power assembly 2 from sliding sideways, further firmly clamping and fixing the power assembly 2 to the housing 1.

[0064] In addition, the grounding wire 21 of the power supply assembly 2 extends to the connection between the fixed bracket 3 and the housing 1, and the end of the grounding wire 21 away from the power supply assembly 2 is connected to a terminal 22; the first fastener 4 is connected to the grounding wire 21 through the terminal 22, and the terminal 22 is located between the first fastener 4 and the first bent portion 31; at the same time, a serrated washer 23 and a flat washer are arranged in sequence between the first bent portion 31 and the terminal 22.

[0065] By simply twisting the first fastener 4, the connection and separation between the first end of the fixing bracket 3 and the housing 1 can be completed, thereby realizing the fixing and disassembly of the power supply component 2; at the same time, the electrical connection between the grounding wire 21 of the power supply component 2 and the housing 1 is completed, thereby completing the grounding operation of the power supply component 2.

[0066] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
