Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] A frame includes a frame body 1 and a front cover 2 mounted on the frame body 1. The frame body 1 is used to mount on a table, and the front cover 2 is mounted on the frame body 1. During installation, the frame body 1 with the front cover 2 can be directly mounted on the panel of a mahjong machine. It also includes a control unit 3 and a light assembly 4. The control unit 3 is located on the back side of the front cover 2, and the light assembly 4 is electrically connected to the control unit 3. The front cover 2 has a switch area 5. The control unit 3 controls the power supply to the light assembly 4. By operating the switch area 5, the control unit 3 can be turned on or off. The light from the light assembly 4 can be displayed externally through the front cover 2. This design increases the functionality of the frame and enhances its overall quality. Specifically, the switch area 5 acts as a switch to turn the light assembly 4 on and off, and this function is achieved through the on / off operation of the control unit 3.

[0022] In this design, the switch area 5 includes a control unit 6, located on the back of the front cover 2. During operation, the switch area 5 includes an operating part, located at the front end of the front cover 2, and the control unit 6 at the rear end. The extension and retraction of the control unit 6 can be achieved by manipulating the operating part. This method of controlling the extension and retraction of the light is a common technique in the mechanical field and will not be elaborated upon in this embodiment. The control unit 6 and the control part 3 form a magnetic switch. The switch area 5 controls the contact or separation of the control unit 6 and the control part 3. That is, the operating part controls the extension and retraction of the control unit 6 to achieve contact or separation with the contact part. Contact here does not only refer to direct contact, but also to contact when the two are close enough to a certain distance to meet the power-on / off conditions.

[0023] In this embodiment, the control unit 3 includes a control circuit board body 7 and contact parts 8 disposed on the body 7. The contact parts 8 contact or disengage from the control unit 6 to control the opening or closing of the lamp assembly 4. The contact parts 8 and the control unit 6 are equivalent to the two ends of a magnetic switch to realize the function of a magnetic switch. In this embodiment, the control unit 3 is mounted on the frame 1. Specifically, the control unit 3 is a PCB circuit board, and the control unit 3 is fixedly connected to the back of the frame 1 by screws.

[0024] In this embodiment, the front cover 2 is provided with a slot 9 for mounting the weight box 17, and the weight box 17 is installed in the slot 9. The weight box 17 is detachably connected, and both ends of the weight box 17 are provided with a retaining plate structure for cooperating with the slot 9. Both ends of the weight box 17 are placed in the slot 9.

[0025] In this embodiment, a limiting shell 10 is formed on the back of the frame 1. The limiting shell 10 and the edge of the frame 1 form a mounting cavity 11. The back of the front cover 2 extends into the mounting cavity 11, so the weight box 17, lamp assembly 4, etc. are all located in the mounting cavity 11, which is safer in actual use. In this solution, a shaft portion 13 is provided at the left end and / or the right end of the mounting cavity 11. Specifically, a shaft portion 13 is provided at both the left and right ends. The shaft portion 13 is fixedly connected to the side of the mounting cavity 11. In this embodiment, it is integrally formed. A corresponding rotating portion 12 is provided at the left end and / or the right end of the front cover 2. The rotating portion 12 is assembled with the shaft portion 13. The front cover 2 can rotate around the shaft portion 13 through the assembly of the rotating portion 12 and the shaft portion 13. Specifically, the rotating portion 12 in this embodiment is a bayonet structure. The rotating portion 12 is fitted onto the shaft portion 13 and can rotate around the shaft portion 13, thereby realizing the flipping opening and closing of the front cover 2, which facilitates the taking and putting away of weights. Specifically, the shaft portion 13 is located at the lower end of the left and right sides of the mounting cavity 11. A partition 20 is provided in the middle of the mounting cavity 11, and the shaft portion 13 is provided on the partition 20. A rotating part 12 is provided at the corresponding position on the front cover 2.

[0026] To prevent the front cover 2 from automatically flipping over during actual use and to maintain its positional stability, and to avoid the front cover 2 shaking or opening automatically, the frame 1 and the front cover 2 are assembled and positioned on the left and / or right sides using positioning structures. Specifically, positioning structures are provided at both the left and right ends. The positioning structures include positioning grooves 14 and positioning blocks 15. The opening of the positioning groove 14 is arc-shaped and faces downward. When the front cover 2 and the frame 1 are in a closed state, the positioning block 15 is confined within the positioning groove 14. A partition 20 is provided in the middle of the mounting cavity 11, and positioning structures are provided on both sides of the partition 20. One of the positioning grooves 14 and the positioning block 15 is located on the partition 20, and the other is located on the front cover 2.

[0027] In this embodiment, the lamp assembly 4 includes a lampshade 16 with a light strip, and the lampshade 16 is a long strip fixed to the back of the front cover 2.

[0028] Compared with the existing technology, this solution has the following advantages: the frame structure has fewer parts and is easy to assemble. Moreover, the light group and control switch are integrated on the front cover 2, which facilitates later maintenance. At the same time, the weight box 17 adopts a detachable design, which can be adjusted as needed.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that both the front cover 2 and the frame 1 are plastic parts.

[0031] Example 3

[0032] The difference between this embodiment and embodiment 1 is that the front cover 2 and the frame 1 are both integrally formed structures.
