However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work all fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 , a combined mahjong machine frame, including four connecting rods 1 enclosing a square structure, and a splicing mechanism provided on each connecting rod 1 for fixing one end of two adjacent connecting rods 1. The end faces of both ends of the connecting rod 1 are connecting inclined surfaces 3 inclined at 45 degrees, and a positioning groove 4 is opened at a position adjacent to the top side of the connecting rod 1 on the connecting inclined surface 3. The splicing mechanism includes a positioning block 8 fixedly provided on the surfaces of two connecting inclined surfaces 3 and adjacent to the bottom side of the connecting rod 1, a clamping block 10 movably penetrating through a lifting groove 9 opened on the end face of the positioning block 8, and a control component provided on the end of the connecting rod 1 for controlling the clamping block 10 to penetrate into or out of the clamping hole 5. The positioning block 8 is penetrated into the positioning groove 4, and a clamping hole 5 matching the clamping block 10 is opened on the groove wall of the positioning groove 4 adjacent to the opening of the lifting groove 9.

[0020] As Figures 1-5 shown, when the frame is damaged, the four connecting rods 1 are disassembled, the damaged connecting rod 1 is replaced, and then the positioning blocks 8 provided on the connecting inclined surfaces 3 at the ends of the four connecting rods 1 are penetrated into the positioning grooves 4, and the four connecting rods 1 are arranged around the square structure, and the positioning blocks 8 are penetrated into the positioning grooves 4. The control component drives the clamping block 10 to move into the clamping hole 5 in the lifting groove 9. When one end of the clamping block 10 penetrates into the clamping hole 5, it is convenient to fix the position of the positioning block 8 in the positioning groove 4, and it is convenient to fix the positions of the four connecting rods 1, that is, to realize the rapid repair of the mahjong machine frame, and avoid replacing and repairing the whole frame, reduce the repair cost, can conveniently repair and replace the mahjong machine frame, avoid the cumbersome steps of replacing the whole frame, and reduce the repair and replacement cost.

[0021] The clamping block 10 is made of an iron block. The control assembly includes a positioning magnet movably penetrating through the bottom wall of the clamping hole 5, and a control member disposed on the connecting rod 1 and configured to control the movement of the positioning magnet towards the middle position of the rod body of the connecting rod 1. A sliding groove 6 is formed between the adjacent hole walls of the two clamping holes 5, and the positioning magnet can movably penetrate through the sliding groove 6.

[0022] As Figures 2-3 shown, when the positioning block 8 penetrates into the positioning groove 4, the position of the clamping block 10 disposed in the lifting groove 9 is opposite to the position of the positioning magnet. Under the magnetic attraction of the positioning magnet, one end of the clamping block 10 penetrates into the clamping hole 5, thereby fixing the position of the positioning block 8 in the positioning groove 4.

[0023] Control ports are formed in the middle of the top and bottom surfaces of the connecting rod 1, and the control ports communicate with the inside of the sliding groove 6. The control member includes two sliding rods 7 respectively movably penetrating through the sliding grooves 6 on both sides of the control port, two control blocks 14 penetrating through the control port and having their mutually remote ends respectively fixedly connected to the adjacent ends of the two sliding rods 7, and an elastic structure disposed between the two control blocks 14. When the elastic structure is in a normal extended state, the two positioning magnets respectively penetrate through the bottom walls of the two clamping holes 5 formed in the rod body of the same connecting rod 1, and the two positioning magnets are respectively fixedly connected to the mutually remote ends of the two sliding rods 7.

[0024] As Figures 3-4 shown, when it is necessary to disassemble between two adjacent connecting rods 1, by controlling the mutual approach of the two control blocks 14 penetrating through the control port 2, the elastic structure is compressed, and the two positioning magnets are driven by the two sliding rods 7 to move towards the middle position of the rod body of the connecting rod 1. When the positioning magnet leaves the bottom wall of the clamping hole 5, at this time, the clamping block 10 will move into the lifting groove 9 under the action of gravity. At this time, it is convenient to move the positioning block 8 penetrating into the positioning groove 4 to the outside of the positioning groove 4, thereby facilitating the disassembly between the two connected connecting rods 1 for subsequent replacement of the connecting rod 1.

[0025] The elastic structure includes a fixed block 11 disposed between the two control blocks 14 and fixedly arranged on the inner wall of the control port 2, a telescopic rod 12 penetrating through the fixed block 11 and the control block 14 and having its two ends respectively fixedly connected to the adjacent end faces of the fixed block 11 and the control block 14, and a limiting spring 13 movably sleeved on the rod body of the telescopic rod 12 and having its two ends respectively fixedly connected to the two ends of the telescopic rod 12.

[0026] As Figure 4 shown, when the two control blocks 14 are controlled to approach each other, the limiting spring 13 sleeved on the rod body of the telescopic rod 12 will be compressed. After releasing the action on the control block 14, under the action of the limiting spring 13, the two control blocks 14 will be driven to move away from each other, that is, drive the positioning magnet to move to the position of the bottom wall of the clamping hole 5.

[0027] A moving groove 15 is formed in the groove wall of the lifting groove 9 in the vertical direction, and a moving block 16 is movably inserted into the moving groove 15. The moving block 16 is fixedly connected to the side surface of the clamping block 10.

[0028] As Figure 5 shown, the sliding is performed by the moving block 16 disposed in the moving groove 15, so as to facilitate ensuring the stable lifting movement of the clamping block 10 in the lifting groove 9, and ensuring that the clamping block 10 can be stably inserted into the clamping hole 5.
