[0002] A card sorting machine is a machine that arranges multiple chess and cards for entertainment into a certain shape to assist users in entertainment activities. Mahjong machines are the most common type of card sorting machine. Mahjong machines take up a certain amount of space, which is a problem for transportation or storage of mahjong machines. During transportation, the machine will form bulky goods, increasing transportation costs; when placed indoors, it will also occupy indoor space when not in use, making the already small space even more cramped. Therefore, many existing mahjong machines are made into folding types, and their desktops can be rotated relative to their support bases. When not in use, the desktop can be rotated from a horizontal state to a state that is basically perpendicular to the ground, thereby greatly saving placement space. Due to the weight of the mahjong machine itself, a corresponding base is required to support it. When the mahjong machine is not in use, when the desktop is rotated from a horizontal state to a state that is basically perpendicular to the ground, most of the space will be left on the base on the other side of the corresponding desktop, resulting in the folded mahjong machine still occupying a large space when stored indoors. In the prior art, there is a foldable table frame and a mahjong machine thereof, wherein the base includes a telescopic frame and a positioning frame. When in use, the telescopic frame is pulled out from the positioning frame to ensure the stability of the horizontal position of the tabletop. When not in use, the telescopic frame is inserted into the positioning frame to avoid taking up too much space. In actual use, the telescopic frame is easily stuck in the positioning frame, especially in the process of pulling out or inserting, the two ends of the telescopic frame need to be balanced before insertion or pulling out, which is inconvenient to use. invention

[0027] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] like Figures 4 to 9 As shown, the base for the card sorting machine of the present invention comprises a first connecting seat 2, a second connecting seat 5 and a locking assembly 4. The second connecting seat 5 is rotatably connected to the first connecting seat 2, and the locking assembly 4 is respectively installed on the first connecting seat 2 and the second connecting seat 5. When the second connecting seat 5 and the first connecting seat 2 are in a horizontal state, the second connecting seat 5 is locked on the first connecting seat 2. When the second connecting seat 5 and the first connecting seat 2 rotate, the locking assembly 4 unlocks the second connecting seat 5, and the second connecting seat 5 rotates around the first connecting seat 2, and the card sorting machine is installed on the first connecting seat 2. When the card sorting machine is not in use, the desktop of the card sorting machine is rotated from a horizontal state to a state basically perpendicular to the ground, and then the second connecting seat 5 is rotated to 90 degrees close to the card sorting machine leg 1, which saves the space occupied by the second connecting seat 5 when it is in a horizontal state.

[0029] like Figures 4 to 9 As shown, the first connection seat 2 and the second connection seat 5 are both rectangular structures, and the two rectangular first connection seats 2 and the second connection seats 5 are respectively composed of a rectangular plate and a rectangular tube, and the rectangular tube is evenly distributed at the lower part of the rectangular plate, and is used to support the card sorting machine installed on the first connection seat 2, and improve the supporting effect of the movable bottom plate of the card sorting machine. This arrangement will leave a groove at the lower end of the first connection seat 2 and the second connection seat 5 for installing the locking assembly, and hide the locking assembly 4 at the lower part of the first connection seat 2 and the second connection seat 5 to avoid affecting the overall appearance of the card sorting machine.

[0030] like Figures 10 to 13 As shown, the locking assembly 4 is composed of a base and a rotating shaft with a series of holding mechanisms, which apply and eliminate holding forces when torque is applied. The locking assembly 4 completes the locking and unlocking between the second connecting seat 5 and the first connecting seat 2, that is, when the second connecting seat 5 and the first connecting seat 2 are in a horizontal state, the second connecting seat 5 is locked on the first connecting seat 2. When the second connecting seat 5 needs to be rotated, the locking assembly 4 is unlocked, and the second connecting seat 5 can rotate around the first connecting seat 2.

[0031] like Figures 14 to 20 As shown, the locking assembly 4 includes a locking plate 4-1 and a locking buckle 4-2. The locking plate 4-1 is fixedly arranged on the first connecting seat 2; the locking buckle 4-2 is rotatably arranged on the second connecting seat 5. When the second connecting seat 5 and the first connecting seat 2 are in a horizontal state, the locking buckle 4-2 is buckled on the locking plate 4-1. When the second connecting seat 5 and the first connecting seat 2 rotate, the locking buckle 4-2 is separated from the locking plate 4-1. The locking plate 4-1 and the locking buckle 4-2 replace the telescopic frame and the positioning frame in the prior art. The locking buckle 4-2 is buckled with the locking plate 4-1, which is convenient for fixing the second connecting seat 5 and the first connecting seat 2 and for rotating the second connecting seat 5 and the first connecting seat 2.

[0032] like Figures 16 to 20 As shown, the locking plate 4-1 and the locking buckle 4-2 can be used as a group to lock and unlock the second connecting seat 5 and the first connecting seat 2. At the same time, multiple groups can also be set to complete the locking and unlocking of the second connecting seat 5 and the first connecting seat 2, thereby improving the connection performance of the second connecting seat 5 and the first connecting seat 2. In this embodiment, two groups are preferably set.

[0033] like Figures 14 to 16 As shown, the locking assembly 4 also includes a connecting plate 4-4, one end of which is rotatably set on the locking plate 4-1, and the other end is fixedly connected to the second connecting seat 5. Since the locking plate 4-1 is fixedly connected to the first connecting seat 2, one end of the connecting plate 4-4 is rotatably connected to the locking plate 4-1, and the other end of the connecting plate 4-4 is fixedly connected to the second connecting seat 5. In this way, the second connecting seat 5 can be rotatably connected around the first connecting seat 2.

[0034] like Fig.15 As shown, in order to realize the rotational connection between the second connecting seat 5 and the first connecting seat 2 or to lock the second connecting seat 5 on the first connecting seat 2, the lock buckle 4-2 is rotatably set on the connecting plate 4-4, so that when the second connecting seat 5 and the first connecting seat 2 are set in a horizontal state, the lock buckle 4-2 is just buckled on the lock plate 4-1; when the second connecting seat 5 rotates upward around the first connecting seat 2, the lock buckle 4-2 is just separated from the lock plate 4-1.

[0035] like Figures 14 to 16As shown, in order to facilitate the staff to unlock and lock, and realize the rotation and locking of the second connecting seat 5 around the first connecting seat 2, a sliding through hole is set on the connecting plate 4-4, and a sliding rod is set in the sliding through hole. The sliding rod is slidably connected with the sliding through hole, and a pull rod 4-3 is set on the lock buckle 4-2. The pull rod 4-3 is connected to the sliding rod through a connecting rod, and the two ends of the connecting rod are respectively movably connected with the pull rod 4-3 and the sliding rod. The sliding rod is pulled to slide backward in the sliding through hole, and the connecting rod and the pull rod 4-3 move backward, thereby driving the lock buckle 4-2 to disengage from the lock plate 4-1 to unlock, and lift the second connecting seat 5 to rotate around the first connecting seat 2; when locked, after the second connecting seat 5 is horizontal with the first connecting seat 2, the sliding rod is pushed to slide forward in the sliding through hole, driving the connecting rod and the pull rod 4-3 to move forward, thereby driving the lock buckle 4-2 to buckle on the lock plate 4-1 to lock, thereby completing the locking of the second connecting seat 5 on the first connecting seat 2.

[0036] like Fig.16 As shown, it is convenient for the staff to unlock and lock again. The buckle 4-2 is connected with the connecting plate 4-4 by a rotating member. The rotating member is an equal height screw. The threaded part of the equal height bolt is threadedly connected with the connecting plate 4-4. The buckle 4-2 is sleeved on the shaft of the equal height bolt. At the same time, a torsion spring is passed through the shaft of the equal height bolt. The two ends of the torsion spring are respectively in contact with the buckle 4-2 and the second connecting seat 5. In this way, when the second connecting seat 5 rotates 90 degrees around the first connecting seat 2, since the two ends of the torsion spring are respectively fixed on the buckle 4-1 and the second connecting seat 5, the second connecting seat 5 and the buckle 4-1 rotate around the center of the torsion spring. The torsion spring rotates the force arm around the central axis of the spring body to statically fix the second connecting seat 5, that is, the second connecting seat 5 is stationary on the first connecting seat 2 at 90 degrees; the torque or rotational force generated by the torsion spring of the second connecting seat 5 pulls the second connecting seat 5 back to the initial position, that is, pulls the second connecting seat 5 back to the horizontal state with the second connecting seat 2, and the buckle 4-2 is buckled on the lock plate 4-1.

[0037] like Fig.21 Torsion springs are helical springs. The ends of a torsion spring are fixed to other components, and when the other components rotate about the center of the spring, the spring pulls them back to their original position, generating torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating the arm about the center axis of the spring body. These springs are usually close-fitting, but there is a pitch between the coils to reduce friction. They provide resistance to rotation or external forces. The hand of the torsion spring (clockwise or counterclockwise) is determined by the application requirements. The coils are either closely wound or separated to accommodate torsional loads (at right angles to the axis of the spring). The ends of the spring can be wound into hooks or straight torsion arms.

[0038] like Figure 5As shown, a cover plate 4-5 is provided at the lower part of the second connecting seat 5, and the cover plate 4-5 is installed on the connecting plate 4-4. A recessed portion is provided on the cover plate 4-5, and a through hole is provided on the recessed portion. The locking assembly 4 is placed in the recessed portion, and part of the sliding rod is exposed in the through hole. By extending one hand into the through hole, the sliding rod can be pulled to control the locking and unlocking of the lock buckle 42- and the lock plate 4-1.

[0039] like Figures 1 to 3 As shown, the card sorting machine of this example includes a leg 1, the upper end of the leg 1 is equipped with a card machine, and the lower end of the leg 1 is installed on the first connecting seat 2. When the card sorting machine is not in use, the desktop is rotated from a horizontal state to a state basically perpendicular to the ground, and then the second connecting seat 5 is rotated to 90 degrees close to the leg 1 of the card sorting machine, which will save the space occupied by the second connecting seat 5 when it is in a horizontal state.

[0040] like Figure 2~3 As shown, in a specific implementation, the second connecting seat 5 is folded, and the slide bar is pulled backward in the sliding hole with one hand. The slide bar drives the connecting rod and the pull rod 4-3 to move backward, and then drives the lock buckle 4-2 to move relative to each other to release the lock plate 4-1 and unlock it. The second connecting seat 5 is rotated, and one end of the second connecting seat 5 is rotated to 90 degrees around the first connecting seat 2, that is, the connecting plate 4-3 rotates around the lock plate 4-1, and the second connecting seat 5 is stationary on the first connecting seat 2 at 90 degrees, saving the space occupied by the second connecting seat 5 when it is in a horizontal state.

[0041] When in use, put down the second connecting seat 5, push the torque or rotational force generated by the torsion spring of the second connecting seat 5 to pull the second connecting seat 5 back to the initial position, that is, pull the second connecting seat 5 back to the horizontal state with the second connecting seat 2, and at the same time, the buckle 4-2 is buckled on the lock plate 4-1 to lock the second connecting seat 5 on one side of the first connecting seat 3.

[0042] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, some details in the embodiments should not be construed as limiting the present invention, and the present invention shall be protected by the scope defined by the attached claims.
