Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to an embedded cover plate for mahjong machines. Background Art

[0002] The height of the existing mahjong table is generally lower than the surface of the frame around the mahjong machine. When the mahjong machine is idle, if you want to protect the mahjong table, you usually cover it with a cloth, which can only prevent dust. If the mahjong table is hit by a blunt object, it will not be protected. Some users use wooden boards to cover the mahjong table directly. Due to the height difference between the frame and the table surface, the size of the wooden board generally needs to be larger than the size of the mahjong table. Although this method can achieve the purpose, it is inconvenient for users to cover the wooden board every time they use it.

[0003] In addition, when not in use, the mahjong table needs to be stood up for storage to save space. When the mahjong table is stood up, the existing wooden boards will directly fall off and separate from the mahjong table, thereby failing to protect the mahjong table top. Summary of the invention

[0004] The utility model overcomes the shortcomings of the above-mentioned prior art and provides an embedded cover plate for a mahjong machine, including a cover plate and a tightening device. The spring of the tightening device pushes the top ball forward. When installing the cover plate, the cover plate is directly embedded in the mahjong table. The top ball of the tightening device is clamped with the side plate of the mahjong table under the action of the spring elastic force. Therefore, when the mahjong table is erected, the embedded cover plate will not fall off the surface of the mahjong table. When it needs to be disassembled, the user pulls the hand hole upward to pull the cover plate out from the inner side of the mahjong table frame. The operation is very convenient and solves the above-mentioned problems.

[0005] The technical solution of the utility model is achieved in this way:

[0006] An embedded cover plate for a mahjong machine comprises a cover plate embedded in a mahjong table top, wherein the size of the cover plate is smaller than the size of the inner space of a target mahjong table frame, and the thickness is less than the height of the mahjong table frame above the table top; a tightening device is provided on the left and right sides or the upper and lower sides of the cover plate, wherein the tightening device comprises an elastically retractable tightening part, the tightening device is installed inside the side edge of the cover plate, the tightening part protrudes from the side edge end face of the cover plate under the elastic action, and the protruding height of the tightening part is greater than half of the difference between the inner space size of the target mahjong table frame and the size of the cover plate; and a carrying hole is provided on the cover plate.

[0007] The utility model provides an embedded cover plate for a mahjong machine. When in use, the cover plate is embedded in the frame of a mahjong table; the upper and lower widths and the left and right widths of the cover plate are smaller than the upper and lower spaces and the left and right spaces corresponding to the inner space of the mahjong table; the thickness of the cover plate is smaller than the height difference between the mahjong table top and the upper surface of the mahjong table frame. A tightening device is arranged on the two corresponding sides of the cover plate. Since the sum of the size of the cover plate and the height of the tightening part protruding from the side end surface of the cover plate is larger than the inner space size of the mahjong table frame, the cover plate can be embedded in the mahjong table frame and be squeezed by elastic force without falling; therefore, the protruding height of the tightening part on one side of the cover plate is larger than half of the difference between the inner space size of the mahjong table frame and the size of the cover plate. When in use, the tightening parts arranged on the two corresponding sides of the cover plate are in close contact with the inner side of the mahjong table frame. Since the tightening parts are subjected to the outward elastic force, they are always in a state of being squeezed toward the inner side of the mahjong table, thereby making the position of the cover plate and the inner side of the mahjong table relatively fixed. When playing mahjong on the table, the cover needs to be removed. The user pulls the handle hole away from the table surface with his hand. The tightening part is acted upon by external force, overcomes the friction between it and the inner side of the mahjong table frame, and is dragged out of the mahjong table frame, thereby removing the embedded cover. The design is exquisite and easy to use.

[0008] Preferably, the tightening device further comprises a shell, and the tightening part comprises a spring and a top ball; the spring is arranged inside the shell, and a circular hole is arranged at the front end of the shell, the diameter of the circular hole is smaller than the diameter of the top ball, the front part of the top ball passes through the inside of the shell, and the rear part of the top ball is in close contact with the front end of the spring, and the top ball always keeps protruding outward under the action of the spring; the left and right sides or the upper and lower sides of the cover plate are provided with corresponding clamping holes that are tightly matched with the shell. The outer side of the tightening device is the shell, and a spring is arranged inside the shell, the rear end of the spring is clamped with the bottom of the shell, and the front end of the spring is in close contact with the rear part of the top ball, squeezing the rear part of the top ball and providing elastic force for it. When the cover plate is not embedded in the mahjong table, the front part of the top ball passes through the circular hole arranged at the front end of the shell, and at this time, the height of the front part of the top ball protruding from the side end face of the cover plate is the maximum, and the circular hole restricts the top ball from falling out of the shell. When the cover is embedded in the inner side of the mahjong table frame, the top ball is forced inward to squeeze the spring and retract a part inward at the same time. The spring is squeezed to give an outward elastic force to the rear of the top ball, so that the front of the top ball is clamped with the inner side of the mahjong table frame. At this time, the height of the front of the top ball protruding from the side end face of the cover is less than the maximum value.

[0009] Preferably, the distance between the handle holes of the cover plate increases gradually from top to bottom, so that when the user pulls the handle hole away from the mahjong table surface, the fingers can be easily engaged in the handle hole, which is convenient for the pulling operation.

[0010] Preferably, the cover plate includes a thin plate and a frame, the snap-in hole is arranged on the frame, and the thickness of the thin plate is less than the thickness of the frame. As another embodiment, such a design allows a certain distance between the thin plate of the cover plate and the surface of the mahjong table, and when the user pulls the hand-carrying hole with his hand in a direction away from the surface of the mahjong table, even if the hole distance of the hand-carrying hole remains unchanged, the finger can be conveniently snapped into the hand-carrying hole without affecting the pulling operation. In addition, the thin plate is lighter and thinner, saving materials.

[0011] Preferably, at least two tightening devices are provided on the left and right sides or the upper and lower sides of the cover plate, respectively, and are respectively arranged at the ends of the left and right sides or the upper and lower sides. The tightening devices are arranged along the ends so that the cover plate is evenly stressed from top to bottom. Preferably, two tightening devices are provided on the left and right sides or the upper and lower sides of the cover plate, respectively, and are respectively arranged at the ends of the left and right sides or the upper and lower sides.

[0012] Preferably, the left and right sides and the upper and lower sides of the cover plate are provided with tightening devices. The tightening devices are evenly arranged around the cover plate so that the cover plate is evenly stressed and has better stability when embedded.

[0013] The design starting point, concept and beneficial effects of the utility model using the above technical solution are:

[0014] The embedded cover plate for the mahjong machine of the utility model can be directly embedded in the inner side of the mahjong table frame when in use, and plays a good protective role on the mahjong table surface. Since the embedded cover plate of the utility model is mutually clamped with the inner side plate of the mahjong table frame, the embedded cover plate will not fall off the mahjong table surface when the mahjong table is erected. The utility model is easy to operate and can effectively protect the mahjong table surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation of the utility model is as follows:

[0030] Example: Figure 1-9 As shown, the utility model provides an embedded cover plate for a mahjong machine, including a cover plate 1 embedded in the tabletop of a mahjong table 2, wherein the upper and lower widths and the left and right widths of the cover plate 1 are smaller than the upper and lower widths and the left and right widths corresponding to the inner space of the frame of the mahjong table 2; the cover plate 1 includes a thin plate 3 and a frame, wherein the thickness of the thin plate 3 is smaller than the thickness of the frame, and the thickness of the frame is smaller than the height of the frame of the mahjong table 2 above the tabletop. The thin plate 3 is provided with a hand-held hole 5; the frame includes a left frame 41, a right frame 42, an upper frame 43, and a lower frame 44, wherein the left frame 41, the upper frame 43, the right frame 42, and the lower frame 44 are connected in sequence; a top tightening device 6 is provided at the head end and the tail end of the left frame 41, the right frame 42, the upper frame 43, and the lower frame 44, respectively, that is, two top tightening devices 6 are provided on each of the left frame 41, the right frame 42, the upper frame 43, and the lower frame 44, and a total of eight top tightening devices 6 are provided on the cover plate 1.

[0031] like Figure 5 , is a schematic diagram of the internal structure of the tightening device 6. The tightening device 6 comprises a shell 61, an elastically retractable tightening portion, and the tightening portion comprises a spring 62 and a top ball 63; the outer side of the tightening device 6 is the shell 61, and the spring 62 is placed inside the shell 61, the rear end of the spring 62 is clamped with the bottom of the shell 61, and the front end of the spring 62 is tightly attached to the rear of the top ball 63; a round hole 64 is provided at the front end of the shell 61, and the diameter of the round hole 64 is smaller than the diameter of the top ball 63, the front part of the top ball 63 passes through the inside of the shell 61, and the rear end of the top ball 63 is tightly attached to and squeezed with the front end of the spring 62 The spring 62 is compressed, and the top ball 63 always keeps protruding to the outside of the shell 61 under the elastic force of the spring 62; the shell 61 is installed inside the side of the left frame 41, the right frame 42, the upper frame 43, and the lower frame 44, and the top ball 63 protrudes from the side end surfaces of the left frame 41, the right frame 42, the upper frame 43, and the lower frame 44 under the elastic action; the head end and the tail end of the left frame 41, the right frame 42 and the upper frame 43, and the lower frame 44 are correspondingly provided with a snap-in hole 4 that is tightly matched with the shell 61.

[0032] When the cover plate 1 is not embedded in the mahjong table 2, the front of the top ball 63 passes through the circular hole 64 set at the front end of the shell 61, and at this time, the height of the front of the top ball 63 protruding from the side end face of the cover plate 1 is the maximum value, and the circular hole 64 restricts the top ball 63 from falling out of the shell 61. When the cover plate 1 is embedded in the inner side of the frame of the mahjong table 2, the top ball 63 is forced to press the spring 62 inwardly and retract a part inwardly. The spring 62 is squeezed to give the rear of the top ball 63 an outward elastic force, so that the front of the top ball 63 is clamped with the inner side of the frame of the mahjong table 2. At this time, the height of the front of the top ball 63 protruding from the side end face of the cover plate 1 is less than the maximum value.

[0033] Because the sum of the size of the cover plate 1 and the height of the top tightening part protruding from the side end face of the cover plate 1 must be greater than the size of the space inside the frame of the mahjong table 2, the cover plate 1 can be embedded in the frame of the mahjong table 2 and squeezed by the elastic force without falling; therefore, the protruding height of the top tightening part of one side of the cover plate 1 is greater than half of the difference between the size of the space inside the frame of the mahjong table 2 and the size of the cover plate 1. When in use, the top balls 63 of the top tightening part provided on the corresponding two sides of the cover plate 1 are tightly attached to the inner side of the frame of the mahjong table 2. Because the top balls 63 are subjected to the outward elastic force, they are always in a state of squeezing toward the inner side of the mahjong table 2, so that the positions of the cover plate 1 and the inner side of the mahjong table 2 are relatively fixed.

[0034] When playing cards on the mahjong table 2, the cover plate 1 needs to be removed. The user pulls the hand hole 5 away from the surface of the mahjong table 2 with his hand, and the top ball 63 is acted upon by an external force, overcomes the friction between it and the inner side of the frame of the mahjong table 2, and is dragged out from the frame of the mahjong table 2, thereby removing the embedded cover plate 1.

[0035] like Figure 1 , is a schematic diagram of the structure when the tightening device 6 is separated from the cover plate 1, and the tightening device 6 is not installed on the side of the cover plate 1 at this time.

[0036] like Figure 2 , which is a schematic diagram of the three-dimensional structure when the tightening device 6 is separated from the cover plate 1. From this angle, it can be seen that the head and tail ends of the left frame 41, the right frame 42 and the upper frame 43, and the lower frame 44 of the cover plate 1 are correspondingly provided with the snap-in holes 4 that are tightly matched with the shell 61.

[0037] like Figure 3 , is a schematic diagram of the structure after the tightening device 6 and the cover plate 1 are combined. At this time, the top ball 63 always keeps protruding to the outside of the shell 61 under the elastic force of the spring 62; because the cover plate 1 is not embedded in the mahjong table 2 at this time, the height of the front part of the top ball 63 protruding from the side end surface of the cover plate 1 is the maximum value at this time.

[0038] like Figure 4 , is a schematic structural diagram of one side of the cover plate 1 after the tightening device 6 is combined with the cover plate 1. It can be seen that the top ball 63 protrudes out of the frame of the cover plate 1.

[0039] like Figure 7 , is a schematic diagram of the three-dimensional structure after the tightening device 6 and the cover plate 1 are combined. From this angle, it can be seen that the top ball 63 protrudes from the side of the cover plate 1.

[0040] like Figure 8 , 9 , is a schematic diagram of the structure in which the cover plate 1 is embedded inside the frame of the mahjong table 2. A diagram of the cover plate 1 of the utility model being embedded inside the frame of the mahjong table 2 in actual use.
