DETAILED DESCRIPTION OF THE EMBODIMENTS

The embodiments of the present application, the objectives and effects thereof will be illustrated in detail below, with reference to the accompanying drawings.

First embodiment

Referring to FIG. 1 to FIG. 9, the first embodiment of the present application relates to a lamp, which is installed, such as in a room, in a park, in a square or on a road, and used for illuminating a specific area.
As shown in FIG. 1, the lamp includes a body 1. The body 1 is provided with an accommodating cavity 11. A detachable mounting plate 2, and clamping plates 4 and a positioning member 5 for positioning the mounting plate 2 on the body 1 are disposed in the accommodating cavity 11. An electrical assembly 3 is fixedly connected to the mounting plate 2. The electrical assembly 3 includes a power supply and a driver, etc. Thus, the whole of the electrical assembly 3 can be installed in the accommodating cavity 11 by installing the mounting plate 2 on the body 1, and the electrical assembly 3 can be taken out from the accommodating cavity 11 by removing the mounting plate 2 from the body 1.
With reference to FIG. 2 to FIG. 4 also, the mounting plate 2 is provided with a plurality of clamping members 21 distributed at intervals. The plurality of clamping members 21 are disposed adjacent to different regions of the mounting plate 2. The clamping plates 4 are consistent with the clamping members 21 in number and are in one-to-one correspondence with the champing members 21. A first positioning groove 22 is provided at one end of the mounting plate 2. The positioning member 5 is located on the side of the mounting plate 2 having the first positioning groove 22. The positioning member 5 includes a positioning plate 6 fixedly connected to the body 1 and a knob 7 movable up and down. The knob 7 is also rotatable around it's axis. The knob 7 is provided with a first protrusion 71, and the first protrusion 71 is extended into the first positioning groove 22 to engage with the first positioning groove 22, which results that the clamping plates 4 are moved into the clamping members 21 and engaged with the clamping member 21. Thus the position of the mounting plate 2 relative to the body 1 is fixed, and the electrical assembly 3 is mounted on the body 1.
In an embodiment, the knob 7 is further provided with a second protrusion 72. The first protrusion 71 and the second protrusion 71 are spaced apart from each other in a vertical direction. The positioning plate 6 is provided with a second positioning groove 61 to engage with the second protrusion 72. The second protrusion 71 is moved into the second positioning groove 61 and engages with the second positioning groove 61 to avoid the rotation of the knob 7. Thus the knob 7 is maintained at a state of locking the mounting plate 2.
Referring to FIGS. 2 and 4, a second threaded hole 24 is provided on the mounting plate 2, and a first mounting hole 31 is provided on the electrical assembly 3 to be aligned with the second threaded hole 24. The electrical assembly 3 can be fixed on the mounting plate 2 by a screw whose end passes through the first mounting hole 31 and connects the second threaded hole 24. Third threaded holes 13 are provided on the body 1 for mounting the clamping plates 4, and a second mounting hole 41 is provided on each clamping plate 4 to be aligned with a corresponding third threaded hole 13. A connecting piece, such as a screw, passes through the second mounting hole 41 and engages with the corresponding third threaded hole 13 to fix the clamping plate 4 on the body 1.
As shown in FIG. 5 and FIG. 6, when the electrical assembly 3 is needed to be installed on the body 1, the clamping members 21 on the mounting plate 2 are aligned with the clamping plates 4 in an one-to-one manner and engaged with the clamping plates 4. Then the knob 7 is rotated to align the first protrusion 71 with the first positioning groove 22, and the second protrusion 72 with the second positioning groove 61. The control knob 7 is further moved in a vertical direction to make the first protrusion 71 move into the first positioning groove 22, and the second protrusion 72 move into the second positioning groove 61. At this time, the mounting plate 2 abuts against the clamping plates 4 under the action of the knob 7 and the electrical assembly 3 is thus fixed on the body 1. The positioning plate 6 abuts against the knob 7 and the knob 7 is thus prevented from rotating and kept in a locked state. When the electrical assembly 3 is needed to be removed from the body 1, the knob 7 can be pressed and moved in the vertical direction. The knob 7 drives the first protrusion 71 to exit the first positioning groove 22 and the second protrusion 72 to exit the second positioning groove 61. Then the knob 7 is rotated to misalign the first protrusion 71 with the first positioning groove 22. At this time, the mounting plate 2 can be pulled out from the clamping plates 4, and the mounting plate 2 and the electrical assembly 3 can be taken off from the body 1.
In detail, in this embodiment, the knob 7 is provided with two first protrusions 71. The two first protrusions 71 are arranged at intervals along a length direction of one side of the knob 7 close to the mounting plate 2. The mounting plate 2 is provided with two first positioning grooves 22. A distance between the two first positioning grooves 22 is equal to a distance between the two first protrusions 71, and the two first positioning grooves 22 are in one-to-one correspondence with the two first protrusions 71, which ensures that the knob 7 is in stable contact with the mounting plate 2. The knob 7 is further provided with two second protrusions 72. The two second protrusions 72 are arranged at intervals along a circumferential direction of the knob 7. The positioning plate 6 is provided with three second positioning grooves 61, and the three second positioning grooves 61 are arranged at intervals along the circumferential direction of the knob 7. An included angle between the two second protrusions 71 is equal to an included angle between every two adjacent second positioning grooves. When the positioning member 5 is in the locked state or the unlocked state, the two second protrusions 72 cooperate with two of the three second positioning grooves 61 to keep the knob 7 in the locked state or the unlocked state. Unintended rotation of the knob 7 is avoided.
In another embodiment, there may be other number of first protrusions 71, such as three or more first protrusions 71. Those first protrusions 71 are distributed along the length direction of one side of the knob 7 close to the mounting plate 2. The first positioning grooves 22 are consistent with the first protrusions 71 in number, and a distance between every two adjacent first positioning grooves 22 is consistent with a distance between every two adjacent first protrusions 71.
In another embodiment, there may be other number of second protrusions 72, such as three or more second protrusions 72. Those second protrusions 72 are distributed along the circumferential direction of the knob 7. The number of the second positioning grooves 61 is greater than that of the second protrusions 72. The second positioning grooves 61 are arranged at intervals along the circumferential direction of the knob 7, and an included angle between every two adjacent second positioning grooves 61 is equal to an included angle between every two adjacent second protrusions 72.
Referring to FIG. 7 and FIG. 8, the positioning member 5 further includes a guiding rod 8. The guiding rod 8 includes a head 81 and a rod 82 connected to the head. The knob 7 is provided with a through hole 73 for the rod 82 to pass through. The guiding rod 8 is extended along the vertical direction. The rod 82 of the guiding rod 8 passes through the through hole 73, and the head 81 of the guiding rod 8 abuts against the knob 7. An outer wall of the rod 82 is provided with threads, and the body 1 is provided with a first threaded hole 12 to engage with the rod 82. The knob 7 is guided to move in the vertical direction by the guiding rod 8 which is fixed on the body 1, and the traveled distance of the knob 7 is limited by abutting the head 81 of the guiding rod 8 against the knob 7. Therefore, the knob 7 is prevented from loosening.
In an embodiment, the positioning member 5 further includes an elastic member 51 sleeved on the guiding rod 8. The elastic member 51 includes two opposite ends along a moving direction of the elastic member 51, one of which abuts against the body 1, and the other of which abuts against a surface of the knob 7 away from the head 81 to move the knob 7 toward the head 81. When the knob 7 abuts against the head 81, the second protrusion 72 is moved into the second positioning groove 61. Thus, the knob 7 can automatically reset when the knob 7 is pressed and moved in the vertical direction, and the knob 7 is kept at a height such that the first protrusion 71 is engaged with the first positioning groove 22 under the action of the elastic member 51. The operation of the knob 7 is more convenient.

Second embodiment

Referring to FIG. 7 and FIG. 9, on the basis of the first embodiment, the second embodiment of the present application adopts another technical solution for the configuration of the mounting plate 2, and the difference between the first embodiment and the second embodiment is only the configuration of the mounting plate 2.
As shown in FIG. 7 and FIG. 9, in this embodiment, each clamping member 21 on the mounting plate 2 includes an extension portion 23. The extension portion 23 is bent towards one side of the mounting plate 2 close to the body 1, and a gap is formed between the extension portion 23 and the mounting plate 2 to receive a corresponding clamping plate 4. When the clamping member 21 is engaged with the corresponding clamping plate 4, the corresponding clamping plate 4 is moved into the gap. The clamping plate 4 abuts against the extension portion 23 and also contacts the mounting plate 2, which keeps the relative position between the clamping plate 4 and the mounting plate 2 stable, and prevents the mounting plate 2 from loosening.
In general, according to the present application, the installation and disassembly of the electrical assembly is realized through the cooperation of the mounting plate, the clamping plates and the positioning member. When to mount the electrical assembly on the body of the lamp, the clamping plates are moved into the clamping members. The knob is pressed and rotated, so that the first protrusion of the knob is engaged with the first positioning groove of the mounting plate, the second protrusion of the knob is engaged with the second positioning groove of the positioning plate and the position of the mounting plate is fixed. When to remove the electrical assembly, the knob is pressed and rotated to exit the first protrusion from the first positioning groove, and then the clamping members are separated from the clamping plates. No more operation is needed. The operation is simple and the installation and disassembly of the electrical assembly is facilitated. The electrical assembly can be quickly taken out or put in by the maintenance operator who overhauls the lamp. The electrical assembly can be installed or disassembled without removing the lamp from the lamp's installation position. Thus, the maintenance efficiency of the lamp is greatly improved.
The above is only an optional embodiment of the present application, and is not therefore limiting the scope of the present application. Any equivalent structural transformation made based on the contents of the specification and drawings of the present application or any direct/indirect application in other related technical fields under the inventive concept of the present application is included in the claimed scope of the present application.
