It should be understood that, in the present embodiment, the movable connection between the lower support 20 and the board bracket 30 to adjust the support height on at least one side of the puzzle board 50 means that the movable connection between the lower support 20 and the board bracket 30 adjusts the height of at least a portion of the puzzle board 50 which is supported by the lower support 20 and the board bracket 30.
In a first case, an overall of the lower support 20 and the board bracket 30 is movable. For example, the lower support 20 and the board bracket 30 can be displaced, such that an overall height of the puzzle board 50 supported by the lower support 20 and the board bracket 30 is adjusted. The entire puzzle board 50 may be adjusted from a first position to a second position. The first position and the second position are used to represent a change in position of the entire puzzle board 50.
In a second case, a first side of the lower support 20 is connected to a first side of the board bracket 30, and a second side of the lower support 20 is connected to a second side of the board bracket 30. The first side of the board bracket 30 supports a first portion of the puzzle board 50, and the second side of the board bracket 30 supports a second portion of the puzzle board 50. The first portion and the second portion of the puzzle board 50 may refer to portions near edges of the puzzle board 50 in a length direction of the puzzle board 50. A common side of the lower support 20 and the board bracket 30, i.e., either the first side or the second side thereof, is movable. For example, the first side thereof may be displaced, such that the height of the first portion of the puzzle board 50 supported by the first side of the lower support 20 and the first side of the board bracket 30 is adjusted, and the height of the second portion of the puzzle board 50 supported by the second side of the lower support 20 and the second side of the board bracket 30 is unchanged. In this way, the puzzle board 50 is changed from a first state to a second state. It should be understood that the first state is different from the second state. In the present disclosure, a support surface is defined, for example, the support surface refers to a surface on which the puzzle board 50 is placed. The support surface may be substantially parallel to a horizontal plane. Exemplarily, in the first state, the puzzle board 50 is substantially parallel to the support surface. In other words, the puzzle board 50 is substantially horizontally placed. In the second state, the puzzle board 50 is inclined with respect to the support surface, i.e., the puzzle board 50 is in an inclined state.
In a third case, at least one of the lower support 20 and the board bracket 30 has at least two sub-portions, and the puzzle board 50 has at least two sub-portions. One sub-portion of the at least two sub-portions of the lower support 20, one sub-portion of the at least two sub-portions of the board bracket 30, and one sub-portion of the at least two sub-portions of the puzzle board 50 are connected to each other correspondingly. At least one sub-portion of the lower support 20 is movably connected to the at least one sub-portion of the board bracket 30 to adjust the height of at least one sub-portion of the puzzle board 50. In an example, a first sub-portion of the lower support 20 is movably connected to a second sub-portion of the board bracket 30 to adjust a height of a third sub-portion of the puzzle board 50.

A size of the second channel 422 is not smaller than a size of the first channel 421. The second channel 422 allows the support rod 31 to pass through. Exemplarily, the size of the second channel 422 is greater than the size of the first channel 421. An outer periphery of the support tube 21 is larger than the size of the first channel 421. After the sleeve tube 41 sleeves the support tube 21, the support tube 21 is restricted in the second channel 422 and is prevented from extending into the first channel 421.
Exemplarily, a cross section of the support rod 31 is circular, a cross section of the support tube 21 is square, the first channel 421 is a circular channel, and the second channel 422 is a square channel. To be noted that, in the present embodiment, the shape of the support rod 31 and the shape of the support tube 21 are not limited by the present disclosure. The shapes herein are exemplary only and do not limit the shapes thereof.
Exemplarily, the support tube 21 is quadrangular, the support rod 31 is cylindrical, and the receiving channel 211 is a circular channel. The tube channel 42 includes a circular channel and a quadrangular channel communicated with the circular channel.

In this way, when the support height is adjusted, a relative height difference between the lower support 20 and the board bracket 30 can be changed by threading the internally-threaded tube sleeve, such that the support height formed by the lower support 20 and the board bracket 30 can be adjusted. When the movable connection is the telescopic-driving connection, a telescopic drive cylinder is mounted on the lower support 20, and a telescopic rod on the telescopic drive cylinder is connected to the board bracket 30. The telescopic drive cylinder drives the board bracket 30 to move up and down to change the support height. When the movable connection is splicing connection, each of the lower support 20 and the board bracket 30 is formed by splicing a plurality of blocks. Each block defines a rod hole in which a rod is inserted. In this way, the support height is adjusted by the lower support 20 and rod insertion.
In the present embodiment, the lower support 20 may be a one-piece frame, and the board bracket 30 may be a one-piece frame. In this way, heights of two sides of the board bracket 30 can be adjusted synchronously. In other embodiments, the lower support 20 may be formed by a plurality of support assemblies assembled to each other, and the board bracket 30 may be formed by a plurality of bracket assemblies assembled to each other. The plurality of support assemblies and the plurality of bracket assemblies may be connected in one-to-one correspondence to each other to form a plurality of support surfaces at a plurality of sides. In this way, the support height of one side or support heights of the plurality of sides can be adjusted based on demands. When there is a difference in heights of different support surfaces, the puzzle board 50 is tilted at an angle relative to the horizontal plane.
Exemplarily, the puzzle board 50 includes a puzzle carrying board 52, a support board 51, and a movable support member 53. The puzzle carrying board 52 is arranged above the support board 51.

The puzzle carrying board 52 is switchable, by the movable support member 53, between a state in which the puzzle carrying board 52 is placed flat on the support plate 51 and a state in which the puzzle carrying board 52 is tilted to have an angle with respect to the support plate 51.
One end of the puzzle carrying board 52 is hinged to one end of the support board 51, forming a hinged portion. The movable support member 53 is disposed below a portion of the puzzle carrying board 52 away from the hinged portion. Specifically, one end of the movable support member 53 is hingedly connected to the puzzle carrying board 52 or the support board 51.
Exemplarily, as shown in
In other embodiments, an end of the movable support member 53 is hinged with the support plate 51. Two oppositely disposed limiting strips are mounted on a bottom surface of the puzzle carrying board 52. When in use, the other end of the movable support member 53 is received between the two limiting strips and is limited by the two limiting strips.
In other embodiments, the puzzle carrying board 52 abuts against the support plate 51. In this case, the movable support member 53 may be an inclined support stage, and a height thereof is adjustable. In this way, the movable support member 53 may be placed on the support plate 51 to abut against the bottom surface of the puzzle carrying board 52, such that the puzzle carrying board 52 is inclined with respect to the support plate 51.
Exemplarily, the jigsaw puzzle table 100 further includes at least one first storage member 60 and/or at least one second storage member 70. The first storage member 60 is movably mounted below a puzzle surface of the puzzle board 50. The first storage member 60 is movable relative to the puzzle board 50 to be opened or closed. The second storage member 70 is movably mounted below the puzzle surface of the puzzle board 50. The second storage member 70 is movable relative to the puzzle board 50 to be opened or closed. Further, a storage cavity size of the first storage member 60 is different from a storage cavity size of the second storage member 70. The first storage member 60 and the second storage member 70 are mounted at different sides of the puzzle board 50. In the present embodiment, a depth of the storage cavity of the second storage member 70 is greater, and therefore, puzzle pieces in a larger size and a larger thickness can be stored in the second storage member 70. In the present embodiment, the first storage member 60 and the second storage member 70 are disposed below the puzzle board 50. In other embodiments, the first storage member 60, the second storage member 70 may be mounted on the puzzle board 50 when a thickness of the puzzle board 50 is large enough, and in this case, the first storage member 60 and the second storage member 70 are located in a cavity below the puzzle surface of the puzzle board 50.
The puzzle surface of the puzzle board 50 refers to a surface away from the lower support 20, or a surface on which the user splices the puzzle pieces.
Exemplarily, the first storage member 60 is located above the second storage member 70. The first storage member 60 is mounted on a side (a short edge) of the puzzle board 50, and the second storage member 70 is mounted on a front (a long edge) of the puzzle board 50. Specifically, a height of the first storage member 60 along a height direction of the puzzle board 50 is greater than a height of the second storage member 70. In this way, the first storage member 60 and the second storage member 70 are disposed at different planes and do not collide each other when being moved. Specifically, to avoid the collision, a bottom surface of the first storage member 60 is higher than a top surface of the second storage member 70.
It should also be noted that, in the present embodiment, the depth of the second storage member 70 disposed on the front of the puzzle board 50 is configured to be greater than the depth of the first storage member 60 disposed on the side of the puzzle board 50. In this way, collision between the second storage member 70 and the first storage member 60, when being moved, is reduced, and in addition, items can be stored therein. It is understood that a length of the front of the puzzle board 50 is greater than a length of the side of the puzzle board 50. In other words, the length of the long edge of the puzzle board 50 is greater than the length of the short edge of the puzzle board 50. In practice, a frequency that the user faces the front of the puzzle board 50 to splice puzzle pieces is higher a frequency that the user faces the size of the puzzle board 50 to splice puzzle pieces. Furthermore, since the length of the side is smaller than the length of the front, more users may face the front of the puzzle board 50 to splice puzzle pieces. Therefore, by considering various factors, the depth of the second storage member 70 disposed at the front of the puzzle board 50 is greater than the depth of the first storage member 60 disposed at the size of the puzzle board 50. Therefore, the user may store or take out items conveniently. More specifically, the first storage member 60 disposed on the side of the puzzle board 50 means that the first storage member 60 may be pulled out of the puzzle board 50 from a short edge of the puzzle board 50, and the second storage member 70 disposed on the front of the puzzle board 50 means that the second storage member 70 may be pulled out of the puzzle board 50 from a longer edge of the puzzle board 50.
Exemplarily, the board bracket 30 defines at least one set of sliding slots 32 and/or at least one set of support retaining edges 33. The first storage member 60 is slidably connected to the sliding slots 32, and the second storage member 70 is slidably connected to the support retaining edges 33. In this way, the first storage member 60 may slide along the sliding slots 32, and the second storage member 70 may slide along the support retaining edges 33. Therefore, the sliding is guided and stable.
Exemplarily, as shown in
Exemplarily, as shown in
