[0054] When the second table top 120 is needed, first, move the second table top 120 toward the front of the first table top 110; then, lift the second end of the guide rail 210 upward so that the top surface of the second table top 120 is flush with the top surface of the first table top 110 (i.e., move the second table top 120 to the first position); thereafter, place the locking assembly in a locked state, thereby achieving the purpose of locking the second table top 120 in the first position.

[0055] The storage assembly provided in this embodiment has a simple structure, reasonable design, and easy operation. By setting the elastic member 220, the second table top 120 can be supported. At the same time, when the second table top 120 is stored, the second table top 120 can also be clamped under the first table top 110, thereby achieving the purpose of improving its storage stability.

[0056] In one embodiment, the storage unit further includes a connector 230 and a roller 240 .

[0057] The connecting member 230 is disposed below the second table top 120 and fixedly connected to the second table top 120. The rollers 240 are rotatably connected to the connecting member 230, and at least two groups of rollers 240 are provided. The at least two groups of rollers 240 are sequentially spaced apart along the width direction of the second table top 120. In this embodiment, two groups of rollers 240 are provided.

[0058] The guide rails 210 of the two storage units are provided with guide grooves 211 on opposite sides thereof. Preferably, the opening of the guide grooves 211 is narrow, that is, the cross section of the guide rails 210 is C-shaped. The rollers 240 are rotatably disposed in the guide grooves 211 .

[0059] In this embodiment, the roller 240 is provided to reduce friction, thereby facilitating the movement of the second table top 120 .

[0060] In one embodiment, each group has two rollers 240 , and the two rollers 240 in each group are spaced apart in the longitudinal direction, and the upper roller 240 abuts against the upper inner wall of the guide groove 211 , and the lower roller 240 abuts against the lower inner wall of the guide groove 211 .

[0061] In this embodiment, two rollers 240 are provided in each group of rollers 240, and the upper roller 240 is in contact with the upper inner wall of the guide groove 211, and the lower roller 240 is in contact with the lower inner wall of the guide groove 211, thereby helping to guide and limit the sliding of the second table top 120.

[0062] In one embodiment, the guide rail 210 includes a first guide segment 212 and a second guide segment 213, wherein the first end of the first guide segment 212 is hinged to the first table top 110, and the second end extends toward the front side of the first table top 110, and the first end of the second guide segment 213 is fixedly connected to the second end of the first guide segment 212, and the second end extends toward the front side of the first table top 110, wherein the angle between the first guide segment 212 and the second guide segment 213 is α, wherein α is an obtuse angle. Preferably, the first guide segment 212 and the second guide segment 213 are integrally formed.

[0063] In this embodiment, by setting the guide rail 210 into two sections and making the angle α between the first guide section 212 and the second guide section 213 an obtuse angle, the purpose of the second guide section 213 extending in the horizontal direction when the second table top 120 is in the first position is achieved. At the same time, the purpose of the first guide section 212 extending in the horizontal direction when the second table top 120 is in the second position is achieved, thereby achieving the purpose of saving the space occupied by the second table top 120 when stored.

[0064] In one embodiment, the storage assembly further includes a connecting rod 250 , and both ends of the connecting rod 250 are respectively fixedly connected to the guide rails 210 of the two storage units.

[0065] In this embodiment, the connecting rod 250 is provided to improve the overall rigidity of the storage assembly.

[0066] In one embodiment, the locking assembly includes a locking receptacle 310 , a locking pin 320 , and an actuation arm 330 .

[0067] The locking hole 310 is provided on one of the first table board 110 and the second table board 120, and the locking pin 320 is slidably provided on the other of the first table board 110 and the second table board 120. In this embodiment, the locking hole 310 is provided on the front side of the first table board 110, and the locking pin 320 is slidably provided on the rear side of the second table board 120. Specifically, the rear side of the second table board 120 is provided with an installation cavity 121, and the locking pin 320 is slidably installed in the installation cavity 121.

[0068] The locking pin 320 has a third position and a fourth position, and the locking pin 320 can make a reciprocating linear motion between the third position and the fourth position along the length direction of the installation cavity. When the locking pin 320 is in the third position, the locking pin 320 extends beyond the side wall of the first table board 110 or the second table board 120, so that the locking slot pin can be inserted into the locking hole 310, thereby making the locking assembly in a locked state; when the locking pin 320 is in the fourth position, the locking pin 320 retracts into the side wall of the first table board 110 or the second table board 120, so that the locking pin 320 cannot be inserted into the locking hole 310, thereby achieving the purpose of making the locking assembly in an unlocked state. The driving arm 330 is fixedly connected to the locking pin 320, and the driving arm 330 is used to drive the locking pin 320 to make a reciprocating linear motion between the third position and the fourth position. Specifically, a first end of the driving arm 330 is fixedly connected to the locking pin 320 , and a second end thereof extends to the outside of the first table top 110 or the second table top 120 .

[0069] When in use, when the second table top 120 is placed in the first position, the locking pin 320 is moved to the third position by the driving arm 330, so that the locking pin 320 is inserted into the locking hole 310, thereby achieving the purpose of keeping the second table top 120 in the first position. When the second table top 120 needs to be moved to the second position, the locking pin 320 is moved to the fourth position by the driving arm 330, so that the locking pin 320 is pulled out of the locking hole 310, thereby achieving the purpose of unlocking the second table top 120.

[0070] In this embodiment, the locking assembly has a simple structure, reasonable design and convenient operation.

[0071] In one embodiment, the locking assembly further includes a positioning member 340, two positioning members 340 are provided, and the two positioning members 340 are respectively provided on both sides of the driving arm 330, and a magnetic attraction force is generated between the positioning member 340 and the driving arm 330. Specifically, at least one of the positioning member 340 or the driving arm 330 is a magnet, and the other is a magnet or made of a magnetic material, such as an iron-containing alloy.

[0072] During use, when the locking pin 320 is moved to the third position, the positioning member 340 at the corresponding position will attract the driving arm 330, thereby maintaining the driving arm 330 at this position, thereby achieving the purpose of maintaining the locking pin 320 at the third position. Similarly, when the locking pin 320 is moved to the fourth position, the positioning member 340 at the corresponding position will attract the driving arm 330, thereby maintaining the driving arm 330 at this position, thereby achieving the purpose of maintaining the locking pin 320 at the fourth position. When the state of the locking assembly is changed, it is necessary to overcome the magnetic attraction between the positioning member 340 and the driving arm 330, thereby achieving the purpose of improving the reliability of the locking assembly.

[0073] In one embodiment, a limiting assembly is further included, and the limiting assembly includes a first limiting member 410 and a second limiting member 420 .

[0074] The first stopper 410 is fixedly connected to the second table top 120. In this embodiment, the first stopper 410 is fixedly connected to the second table top 120 via the connecting member 230. The second stopper 420 is disposed at the front end of the guide rail 210, and the second stopper 420 is fixedly connected to the guide rail 210.

[0075] When the second table top 120 moves to the front end of the guide rail 210 , the first limiting member 410 and the second limiting member 420 conflict with each other, thereby preventing the roller 240 from moving out of the guide groove 211 .

[0076] The utility model also provides a study table, comprising the table shape switching mechanism described in any of the above embodiments.
