Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a host of a mahjong machine. Background Art

[0002] The main body of a conventional mahjong machine consists of a base plate and a panel covering the base plate. The base plate has columns at its corners, and the panel is connected to the columns via hinges. The hinges typically provide support to hold the panel in place when it is flipped open, making it easier to clean or inspect the inside of the mahjong machine.

[0003] However, since the existing hinge with a support function can only be positioned at one angle, the panel can only be positioned at a fixed angle when it is flipped open. The operator cannot adjust the opening angle of the panel. When cleaning or repairing the inside of the mahjong machine, the panel is likely to block the operator's operation, causing inconvenience to the operator. Utility Model Content

[0010] Preferably, an anti-falling block is provided on the limit pin, and the anti-falling block is used to limit the limit pin from falling out of the limit groove in its axial direction.

The connecting rod forms a detachable connection with at least one of the connecting seat and the frame, allowing the panel to be separated from the frame.

[0018] Preferably, the connecting seat is connected to the supporting frame.

[0019] Preferably, the frame includes a plurality of columns fixed to the corners of the bottom plate and a pull rod connecting adjacent columns. When the panel is flipped open, one end of the connecting rod is supported on the column.

[0020] After adopting the above technical solution, the utility model has the following beneficial effects.

[0021] 1. The present invention provides a mahjong machine in which the panel can be selectively positioned at a first opening angle or a second opening angle when in an open state, so that the operator can select the positioning angle of the panel according to needs, thereby improving the convenience of operation.

[0022] 2. When the panel is positioned at the first opening angle α1, the panel has a tendency to tilt toward the bottom plate. The panel in the positioned state does not exceed the range of the bottom plate. When the operator walks around the mahjong machine, the panel will not block the operator's walking route, thereby better meeting the operating needs of the operator when he needs to frequently walk around the mahjong machine or needs to operate on the outer circle of the mahjong machine, thereby improving the operator's operating experience in the above-mentioned operating scenarios.

[0023] 3. When the panel is positioned at the second opening angle α2, the panel has a tendency to tilt away from the bottom plate, and the horizontal projection of the panel at least partially falls on the outside of the bottom. The interior of the mahjong machine can be better exposed to the operator. When the operator inspects or cleans the interior of the mahjong machine, the panel will not block or interfere with the operator's operation, thereby improving the operator's operating experience in the above-mentioned operating scenario.

[0024] 4. The limit groove is in the shape of a long strip, so that the distance between the first limit part and the second limit part is relatively long, thereby widening the angle difference between the first opening angle α1 and the second opening angle α2. When the panel is positioned at the first opening angle α1 or the second opening angle α2, the two relative positions of the panel are quite different. When the panel is positioned at one of the opening angles and will block the operator's operation, the panel can be positioned at another opening angle to avoid obstruction of the panel as much as possible, which helps to improve the convenience of operation; at the same time, the limit pin can slide continuously between the first limit part and the second limit part, and the operator can easily switch the panel between the first opening angle and the second opening angle, further improving the convenience of operation.

[0025] 5. An opening is provided on the connecting seat for the limit pin to enter or exit the limit groove, and the position of the limit groove connecting opening is located between the first limit part and the second limit part. With this arrangement, the limit pin can more easily enter the limit groove, which is convenient for the operator to operate. At the same time, the connecting rod and the limit pin can also be arranged to be integrated or fixedly connected, thereby improving the connection strength between the limit pin and the connecting rod, thereby improving the stability of the connecting rod for panel positioning and the service life of the connecting rod and the limit pin. In addition, when the limit pin abuts against the first limit part or the second limit part, it needs to be moved to disengage from the opening, and the opening has a certain distance from the first limit part or the second limit part. The gravity of the panel acts on the connecting rod to generate friction between the limit pin and the connecting seat, which is not easy to move, thereby better avoiding the limit pin from disengaging from the opening when in the positioning state, thereby improving the stability of the panel during positioning.

[0026] 6. One end of the limit pin is provided with an anti-drop block, and the other end is connected to the connecting rod, thereby limiting the limit pin in the limit groove and preventing the limit pin from detaching from the limit groove in the axial direction, thereby improving the reliability of the connecting rod in positioning the panel.

[0027] 7. Since the limit pin or the connecting rod moves along the axial direction of the limit pin to make the limit pin enter or exit the limit slot, when the limit pin is in the positioning state, external force is required to make the limit pin disengage from the limit slot to make the panel disengage from the positioning state. At the same time, when the panel is in the positioning state, the limit pin is blocked under the panel. Even if the panel or the mahjong machine host is impacted by external force, it is difficult to contact the limit pin. Therefore, it is difficult for the limit pin to disengage from the positioning state, and the positioning state of the panel is also quite stable. Through the above-mentioned settings, the stability of the limit pin in the positioning state can be improved, thereby improving the stability of the panel in the positioning state.

[0028] 8. The connecting rod is detachably connected to the frame, and the installation, removal and replacement of the connecting rod are relatively easy, which helps to reduce assembly and maintenance costs.

[0029] 9. Due to the rotational connection between the connecting rod and the frame, on the one hand, the movement of the connecting rod is relatively easy, and the operator can easily move the connecting rod to position the panel, switch the panel positioning state or release the panel positioning. On the other hand, the rotation of the connecting rod can also cause the connecting rod to rotate and be hidden in the frame. When the connecting rod is needed, the connecting rod can be rotated and taken out, thereby improving the convenience of storage and use of the connecting rod.

[0030] 10. When the panel is flipped open, the elastic element acts on the connecting rod so that the connecting rod rotates and flips out as the panel opens. The operator can easily operate the connecting rod to position the panel, which improves the convenience of connecting rod operation.

[0031] 11. During the flipping and closing process of the panel, the connecting rod is pressed to rotate in a second direction opposite to the first direction, and the elastic element is compressed to provide damping. In this way, the flipping and closing of the panel will not fall directly due to the resistance of the elastic element, and the closing of the panel will be more labor-saving. It is also not easy for the panel to hit the frame and be damaged when it is closed.

[0032] 12. A positioning pin is also provided on the connecting rod, which can be stopped by the frame to limit the connecting rod from rotating in the first direction. With this arrangement, the storage of the connecting rod is more stable and reliable, and the removal of the connecting rod is also safer. When the operator flips the closed panel open quickly, the connecting rod will not pop out quickly.

[0033] 13. The support frame and the frame are detachable structures. At the same time, the connecting rod is detachably connected to at least one of the connecting seat and the frame, and the panel and the frame are separable. When the two opening angles of the panel cannot meet the operator's operating needs, the panel can also be removed from the main body of the mahjong machine, further improving the operator's operating convenience.

[0034] 14. The connecting seat is connected to the support frame. In this way, the connecting seat and the support frame form an integrated structure. On the one hand, it can save a component, reduce material cost and assembly labor cost. On the other hand, the integrated structure makes the connection strength between the two higher, and improves the supporting positioning strength of the connecting seat and the support frame.

[0035] 15. The frame includes several columns fixed to the corners of the base plate and tie rods connecting adjacent columns. When the panel is flipped open, one end of the tie rod is supported on the column. This shortens the distance between the end of the tie rod on the column and the panel, thereby reducing the length of the tie rod, reducing material usage and cost.

[0036] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0053] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" or "several" means two or more, unless expressly limited otherwise.

[0055] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0056] like Figures 1 to 8 As shown, the main body of a mahjong machine proposed in the embodiment of the present invention includes a base plate 100, a panel 200, a card handling mechanism located in the center of the base plate 100, and four groups of card picking and transporting mechanisms arranged on the base plate 100 around the card handling mechanism. Each group of card picking and transporting mechanisms generally includes a card feeding mechanism, a card stacking mechanism, a card pushing mechanism, and a card lifting mechanism. The specific structure and working principle of the card handling mechanism and the card picking and transporting mechanism are well known to those skilled in the art and will not be described in detail in this embodiment. The panel 200 covers the card handling mechanism and the four groups of card picking and transporting mechanisms. The panel 200 is provided with a card inlet and a card lifting port corresponding to the card handling mechanism and the card lifting mechanism.

[0057] A frame 110 is mounted on the base 100, and the panel 200 can be flipped relative to the frame 110 to open or close. The frame 110 includes several columns 111 fixed to the corners of the base 100 and tie rods 112 connecting adjacent columns 111. The base 100 and panel 200 are typically square in shape, and accordingly, there are typically four columns 111 and four tie rods 112.

[0058] In order to facilitate supporting the flipped open panel 200 at different angles, such as Figures 1 to 8 As shown, in one embodiment, the main body of the mahjong machine further includes a connecting base 300 and a connecting rod 400. The connecting base 300 is fixed to the panel 200 and is provided with a limiting groove 330. The limiting groove 330 has a first limiting portion 331 and a second limiting portion 332. When the panel 200 is flipped open, one end thereof is supported on the frame 110. One end of the connecting rod 400 is supported on the frame 110. The other end of the connecting rod 400 is provided with a limiting pin 410. When the limiting pin 410 abuts the first limiting portion 331 in the limiting groove 330, the first opening angle α1 of the panel 200 is maintained. When the limiting pin 410 abuts the second limiting portion 332 in the limiting groove 330, the second opening angle α2 of the panel 200 is maintained.

[0059] In this embodiment, the connecting seat 300 includes a plate-shaped connecting seat body 310 and a connecting plate 320. The plate-shaped connecting seat body 310 is fixed under the panel 200. The connecting plate 320 is formed by extending from one end of the connecting seat body 310 in a direction away from the panel 200, and the limiting groove 330 is provided on the connecting plate 320.

[0060] Since one end of the panel 200 is supported on the frame 110 when it is flipped open, the panel 200 is supported and can rotate relative to the frame 110. Through the cooperation of the limiting pin 410 and the limiting groove 330, the connecting rod 400 can position the panel 200 at the opening angle.

[0061] Through the above arrangement, the panel 200 can be selectively positioned at the first opening angle α1 or the second opening angle α2 when in the open state, so that the operator can select the positioning angle of the panel 200 as needed, thereby improving the convenience of operation.

[0062] In one embodiment, Figure 4 As shown, the limiting groove 330 is in an elongated shape, and the opposite ends of the limiting groove 330 form a first limiting portion 331 and a second limiting portion 332 respectively. The limiting pin 410 can slide continuously between the first limiting portion 331 and the second limiting portion 332.

[0063] The term "elongated" refers to the shape of the limiting groove 330 being relatively long in the longitudinal direction. It is understood that the long side of the limiting groove 330 can be a straight side or an arc-shaped side. Because the limiting groove 330 is elongated, the distance between the first limiting portion 331 and the second limiting portion 332 is relatively long, thereby widening the angular difference between the first opening angle α1 and the second opening angle α2. When the panel 200 is positioned at the first opening angle α1 or the second opening angle α2, the two relative positions of the panel 200 differ significantly. If the panel 200 is positioned at one of the opening angles and would obstruct the operator's operation, the panel 200 can be positioned at the other opening angle, thereby minimizing obstruction by the panel 200 and improving operational convenience. Furthermore, the limiting pin 410 can slide continuously between the first limiting portion 331 and the second limiting portion 332, allowing the operator to easily switch the panel 200 between the first opening angle α1 and the second opening angle α2, further improving operational convenience.

[0064] In order to facilitate the panel 200 to enter or leave the positioning state, as shown in FIG. Figure 4 As shown, in one embodiment, the connection seat 300 is provided with an opening 333 for the limiting pin 410 to enter or exit the limiting groove 330 , and the position where the limiting groove 330 communicates with the opening 333 is located between the first limiting portion 331 and the second limiting portion 332 .

[0065] In this embodiment, the opening 333 is provided at one end of the limiting slot 330 away from the panel 200, the opening 333 is connected to the limiting slot 330 and the first limiting portion 331 and the second limiting portion 332 are provided on both sides of the opening 333. After the limiting pin 410 enters the limiting slot 330 from the opening 333, it moves toward both sides of the limiting slot 330 to abut against the first limiting portion 331 or the second limiting portion 332.

[0066] The locking mechanism 410 is actuated by the locking mechanism 411 and the locking mechanism 412. The locking mechanism 410 is actuated by the locking mechanism 413 and the locking mechanism 414. The locking mechanism 410 is actuated by the locking mechanism 415.

[0067] In one embodiment, Figure 3 、 Figure 5 As shown, the stop pin 410 is provided with an anti-slip block 411, which is used to prevent the stop pin 410 from axially dislodging from the stop slot 330. The anti-slip block 411 can be a nut, a retaining ring, or a nut provided at one end of the stop pin 410. The stop pin 410 is provided with an anti-slip block 411 at one end, and the other end is connected to the connecting rod 400, thereby confining the stop pin 410 in the stop slot 330 and preventing the stop pin 410 from axially dislodging from the stop slot 330, thereby improving the reliability of the connecting rod 400 in positioning the panel 200.

[0068] In order to facilitate the panel 200 to enter or leave the positioning state, in one embodiment, the connecting rod 400 can reciprocate along the axial direction of the limiting pin 410, so that the limiting pin 410 moves to enter or exit the limiting groove 330.

[0069] In this embodiment, the limiting pin 410 is fixed to the connecting rod 400 , and the connecting rod 400 reciprocates along the axial direction of the limiting pin 410 to drive the limiting pin 410 to enter or exit the limiting groove 330 .

[0070] In another embodiment, the stop pin 410 is detachably connected to the connecting rod 400, with one end of the connecting rod 400 restricted in movement within a limited slot. The stop pin 410 axially moves into or out of the limited slot 330 to connect or disconnect with the connecting rod 400. When the panel 200 is open, the stop pin 410 enters the limited slot 330 to position the panel 200; after the stop pin 410 exits the limited slot 330, the panel 200 can be flipped closed.

[0071] Since the limit pin 410 or the connecting rod 400 moves along the axial direction of the limit pin 410, the limit pin 410 enters or exits the limit slot 330. When the limit pin 410 is in the positioning state, external force is required to make the limit pin 410 disengage from the limit slot 330 to allow the panel 200 to leave the positioning state. At the same time, when the panel 200 is in the positioning state, the limit pin 410 is blocked under the panel 200. Even if the panel 200 or the mahjong machine host is impacted by external force, it is difficult to contact the limit pin 410. Therefore, it is difficult for the limit pin 410 to leave the positioning state, and the positioning state of the panel 200 is also quite stable. Through the above-mentioned setting, the stability of the limit pin 410 in the positioning state can be improved, thereby improving the stability of the panel 200 in the positioning state.

[0072] In one embodiment, Figure 7 As shown, the first opening angle α1 of the panel 200 relative to the frame 110 is less than 90°. When the limit pin 410 abuts the first limit portion 331, the connecting rod 400 provides support to the panel 200 to maintain the first opening angle α1 of the panel 200. When the panel 200 is positioned at the first opening angle α1, the panel 200 has a tendency to tilt toward the base plate 100. The horizontal projection of the panel 200 in the positioned state does not exceed the range of the base plate 100. When the operator walks around the mahjong machine, the panel 200 will not block the operator's walking path. This better meets the operating needs of operating scenarios where the operator needs to frequently walk around the mahjong machine or needs to operate on the outer ring of the mahjong machine, and improves the operator's operating experience in such operating scenarios.

[0073] In one embodiment, Figure 8 As shown, the second opening angle α2 of the panel 200 relative to the frame 110 is greater than 90°. When the limit pin 410 abuts the second limit portion 332, the connecting rod 400 provides a pulling force to the panel 200 to maintain the second opening angle α2 of the panel 200. When the panel 200 is positioned at the second opening angle α2, the panel 200 has a tendency to tilt away from the base plate 100. The horizontal projection of the panel 200 at least partially falls outside the bottom, which better exposes the interior of the mahjong machine to the operator. When the operator inspects or cleans the interior of the mahjong machine, the panel 200 will not block or interfere with the operator's operations, thereby improving the operator's operating experience in such operating scenarios.

[0074] In order to facilitate the operator to operate the connecting rod 400, as shown in FIG. Figure 2 、 Figure 3 、 Figures 7 to 10 As shown, in one embodiment, the connecting rod 400 rotates the connecting frame 110 .

[0075] In this embodiment, a hinge seat 120 and a hinge shaft 121 are mounted on the column 111. The hinge seat 120 has a cavity. The hinge shaft 121 passes through the outside of the column 111 and is fixed to the hinge seat 120. A portion of the hinge shaft 121 is positioned within the cavity. The connecting rod 400 is hingedly coupled to the hinge shaft 121 within the cavity, thereby being rotatably connected to the frame 110. The column 111 is correspondingly provided with a mounting hole 1112 for mounting the hinge seat 120 and a screw hole 1113 for threading the hinge shaft 121.

[0076] In some other embodiments, a pin portion is provided on the connecting rod 400 , and the connecting rod 400 is rotatably connected to the column 111 via the pin portion.

[0077] Due to the rotational connection between the connecting rod 400 and the frame 110, on the one hand, the movement of the connecting rod 400 is relatively easy, and the operator can easily move the connecting rod 400 to position the panel 200, switch the positioning state of the panel 200 or release the positioning of the panel 200. On the other hand, the rotation of the connecting rod 400 can also cause the connecting rod 400 to rotate and be hidden in the frame 110. When the connecting rod 400 needs to be used, the connecting rod 400 can be rotated and taken out, thereby improving the convenience of storage and use of the connecting rod 400.

[0078] In order to facilitate the removal of the connecting rod 400, Figure 3 、 Figure 9 、 Figure 10 As shown, in one embodiment, an elastic element 130 is connected between the connecting rod 400 and the frame 110 , and the elastic element 130 maintains the rotation tendency of the connecting rod 400 in a first direction, which is consistent with the opening direction of the panel 200 .

[0079] In this embodiment, the elastic element 130 is a torsion spring, one end of which abuts the frame 110, and the other end abuts the connecting rod 400. The elastic element 130 is pre-loaded between the frame 110 and the connecting rod 400. When the panel 200 is flipped open, the elastic element 130 acts on the connecting rod 400, causing the connecting rod 400 to rotate and flip out as the panel 200 opens. The operator can easily operate the connecting rod 400 to position the panel 200, improving the convenience of operating the connecting rod 400.

[0080] In order to facilitate the storage of the connecting rod 400, as shown in FIG. Figure 3 、 Figure 5 、 Figure 9 、 Figure 10 As shown, in one embodiment, a positioning pin 420 is further provided on the connecting rod 400 , and the positioning pin 420 can be stopped by the frame 110 to limit the connecting rod 400 from rotating in the first direction.

[0081] In this embodiment, a positioning groove 1121 is provided under the pull rod 112 of the frame 110, and a corresponding positioning pin 420 is provided on the connecting rod 400. After the panel 200 is released from the positioning state, the operator presses the connecting rod 400 down and stores it in the frame 110. The positioning pin 420 is positioned on the positioning groove 1121, and the elastic element 130 is pre-pressed between the frame 110 and the connecting rod 400 to press the connecting rod 400 tightly against the frame 110. At this time, the panel 200 can be flipped over and covered.

[0082] A limit block 421 is further provided at one end of the positioning pin 420 away from the connecting rod 400. The limit block 421 and the connecting rod 400 restrict the positioning pin 420 from axially disengaging from the positioning groove 1121, thereby preventing the connecting rod 400 from disengaging when the connecting rod 400 is stored.

[0083] It is understandable that the pull rod 112 may not need to be provided with a positioning groove 1121, and the positioning pin 420 abuts against the lower end surface of the pull rod 112; the pull rod 112 may also be provided with a positioning hole, and the positioning pin 420 is inserted into the positioning hole to position and accommodate the connecting rod 400.

[0084] When the panel 200 is flipped open and the connecting rod 400 needs to be taken out, the stopping relationship between the positioning pin 420 and the frame 110 is released, and the connecting rod 400 can be rotated and taken out under the action of the elastic element 130.

[0085] With this arrangement, the storage of the connecting rod 400 is more stable and reliable, and the removal of the connecting rod 400 is also safer. When the operator quickly flips open the covered panel 200, the connecting rod 400 will not pop out quickly.

[0086] To facilitate storage of the connecting rod 400 , in another embodiment, the panel 200 compresses the connecting rod 400 to rotate in a second direction opposite to the first direction during flipping and closing, and the elastic element 130 is compressed to provide damping.

[0087] When the operator flips and covers the panel 200, the panel 200 abuts against the connecting rod 400, thereby flipping and pressing the connecting rod 400 together. The elastic element 130 is gradually compressed and provides damping for the flipping and covering of the panel 200. In this way, the flipping and covering of the panel 200 will not fall directly due to the resistance of the elastic element 130, and the covering of the panel 200 will be more labor-saving. When the panel 200 is closed, it is not easy to hit the frame 110 and cause damage to the panel 200.

[0088] To facilitate removal and replacement of the connecting rod 400, in one embodiment, the connecting rod 400 is detachably connected to the frame 110. When the panel 200 is open, one end of the connecting rod 400 is connected to the frame 110 to position the panel 200. After the end of the connecting rod 400 is separated from the frame 110, the panel 200 can be flipped closed. This makes installation, removal, and replacement of the connecting rod 400 relatively easy, helping to reduce assembly and maintenance costs.

[0089] like Figures 2 to 6 As shown, in one embodiment, the panel 200 includes a panel body and a support frame 340 fixed to the panel body. When the panel 200 is flipped open, it is freely supported on the frame 110 by the support frame 340. The connecting rod 400 forms a detachable connection with at least one of the connecting seat 300 and the frame 110, allowing the panel 200 to be separated from the frame 110.

[0090] In this embodiment, the support frame 340 includes a support frame body 341 and a hook 342. The support frame body 341 is connected to the panel 200, and the hook 342 extends from the end of the support frame body 341 facing away from the panel 200. When the panel 200 is flipped open, the support frame body 341 is supported on the column 111. The upper end of the column 111 is provided with a downwardly curved flange 1111, and the hook 342 is hooked onto the flange 1111. When the panel 200 is flipped open, the hook 342 is stopped by the flange 1111, preventing the support frame 340 from separating from the column 111.

[0091] In this embodiment, one end of the connecting rod 400 having a stop pin 410 is detachably connected to the connecting base 300, thereby allowing the panel 200 to be separated from the frame 110. The detachable structure of the connecting rod 400 and the connecting base 300 can refer to the above embodiment.

[0092] In some other embodiments, the connecting rod 400 is supported on one end of the frame 110 and is detachably connected to the frame 110, thereby allowing the panel 200 to be separated from the frame 110. The detachable structure of the connecting rod 400 and the frame 110 can refer to the above embodiments.

[0093] Through the above-mentioned arrangement, the support frame 340 and the frame 110 are detachable structures. At the same time, the connecting rod 400 is detachably connected to at least one of the connecting seat 300 and the frame 110, and the panel 200 is separable from the frame 110. When the two opening angles of the panel 200 cannot meet the operating requirements of the operator, the panel 200 can also be removed from the host of the mahjong machine, further improving the operating convenience of the operator.

[0094] In some other embodiments, the panel 200 and the frame 110 are connected by a hinge, including two hinge pieces and a hinge shaft that hinges the two hinge pieces. The two hinge pieces are fixed on the panel 200 and the column 111 respectively. When the panel 200 is flipped open, the hinge forms a support between the panel 200 and the frame 110, and the hinge pieces and the hinge shaft bear the supporting force.

[0095] In this embodiment, since the hinge is fixed to the panel 200 and the frame 110 , it is not necessary to consider whether any one of the connecting rod 400 , the connecting seat 300 and the frame 110 is detachable.

[0096] In one embodiment, Figure 4 As shown, the connecting seat 300 is connected to the support frame 340. In this way, the connecting seat 300 and the support frame 340 form an integrated structure. On the one hand, it can save a component, reduce material costs and assembly labor costs. On the other hand, the integrated structure makes the connection strength between the two higher, thereby improving the supporting and positioning strength of the connecting seat 300 and the support frame 340.

[0097] In one embodiment, Figures 1 to 3 As shown, the frame 110 includes a plurality of columns 111 fixed to the corners of the base plate 100 and a tie rod 112 connecting adjacent columns 111. When the panel 200 is flipped open, one end of the connecting rod 400 is supported on the column 111. This shortens the distance between the end of the connecting rod 400 on the column 111 and the panel 200, thereby shortening the length of the connecting rod 400, reducing the material consumption of the connecting rod 400 and reducing the cost of the connecting rod 400.

[0098] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
