However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0042] It should be noted that these and other subsequent drawings are only examples and are not drawn to scale, and should not be used to limit the actual scope of protection required by the present invention.

[0043] The terms "first", "second", etc. may be used interchangeably to distinguish one feature from another, and are not intended to mean that each feature must be located as shown in the figures in each embodiment.

[0044] like Figure 1 As shown, the lifting platform includes a sliding mechanism. The sliding mechanism includes a first slide rail 1 and a first slider 2, and the first slider 2 can slide vertically along the first slide rail 1. Figure 1 As shown, the lifting platform also includes a platform 3, which is used to support goods. The platform 3 is supported by the first slider 2, so that the first slider 2 slides vertically to drive the platform 3 to rise and fall vertically. The platform 3 can be fixed to the first slider 2. Figure 1 As shown, the lifting platform further includes a sliding control mechanism 4 , which is disposed on the first sliding block 2 . Figures 4 to 6 The structure in the middle is transparent to show the internal structure. Figures 4 to 6 The sliding control mechanism 4 includes a control member 6 and a telescopic member 5. The telescopic member 5 can move in the lateral direction, so that Figure 4 As shown, the telescopic member 5 can protrude from the first slider 2, and the part of the telescopic member 5 protruding from the first slider 2 is inserted into the first slide rail 1, preventing the first slider 2 from sliding vertically along the first slide rail 1. The sliding mechanism is locked, so that the first slider 2 is vertically supported on the first slide rail 1, and the table 3 is fixed in the height direction. The telescopic member 5 can move in the lateral direction, so that, as shown in FIG. Figure 6As shown, the telescopic member 5 can retract the first slider 2, the telescopic member 5 withdraws from the first slide rail 1, the telescopic member 5 is disconnected from the first slide rail 1, the first slider 2 can slide vertically along the first slide rail 1, the sliding mechanism can slide, drive the table 3 to rise and fall vertically, and adjust the vertical height of the table 3. Figures 4 to 6 As shown, the control member 6 can move vertically, thereby controlling the telescopic member 5 to move horizontally, and further controlling the telescopic member 5 to plug into or unplug the first slide rail 1, and adjusting the vertical height of the table 3. Applying a vertical force to the control member 6 causes the control member 6 to move vertically, thereby pushing the first slide block 2 to slide vertically, and driving the table 3 to rise and fall vertically, which is easy to operate. In addition, the vertical height adjustment does not require the table 3 and the goods placed on the table 3 to be removed, which is easy to operate.

[0045] like Figure 1 As shown, the lifting platform can be provided with two sliding mechanisms, each of which includes a first slider 2 and a first slide rail 1. A lateral interval is provided between the two sliding mechanisms, so that there is a lateral interval between the two first sliders 2. The platform 3 is supported by the two first sliders 2, and the structure is more stable. The sliding control mechanism 4 can be provided in the lateral interval between the two first sliders 2. For further reference, Figures 4 to 6 , and the sliding control mechanism 4 is provided with two telescopic parts 5, each sliding mechanism is equipped with a telescopic part 5, each telescopic part 5 controls the locking and sliding of a sliding mechanism, and a control part 6 controls the lateral movement of the two telescopic parts 5, so that one control part 6 controls the locking and sliding of the two sliding mechanisms, making the vertical height adjustment operation of the table top 3 convenient.

[0046] like Figure 1 As shown, the cross-section of the first slide rail 1 may be "C"-shaped, and the first slide rail 1 is provided with a first opening 7 on one lateral side, and the first openings 7 of the two first slide rails 1 are laterally opposite to each other, thereby allowing the later-described pipe fitting 8 of the sliding control mechanism 4 to pass through the first opening 7 to connect to the first slider 2.

[0047] like Figure 1 As shown, the first slide rail 1 may be provided with a plurality of slots 9, and the plurality of slots 9 are arranged in a row vertically. Figure 4 In the embodiment, the telescopic member 5 protrudes from the first slider 2 so as to be inserted into the slot 9, and the sliding mechanism is locked, so that the first slider 2 is vertically supported on the first slide rail 1, and the table 3 is fixed in the height direction. Figure 6 In the embodiment, the telescopic member 5 retracts the first slide block 2 to exit the slot 9, and the first slide block 2 can slide vertically along the first slide rail 1 to adjust the vertical height of the platform 3. The slot 9 can be arranged on the lateral side wall of the first slide rail 1.

[0048] like Figure 3As shown, the first slider 2 can be configured with plastic parts 10 on both sides in the longitudinal direction. The longitudinal side walls of the plastic part 10 are provided with multiple grooves, each groove extends vertically, and multiple grooves are arranged in the transverse direction, so as to reduce the friction of the first slider 2 sliding in the first slide rail 1 and reduce the sliding noise.

[0049] like Figures 4 to 6 As shown, the sliding control mechanism 4 can also be provided with an elastic element 11, which is provided on the lateral side of the telescopic member 5. The elastic element 11 is compressed by the telescopic member 5 and is always in a compressed state. The elastic element 11 always has a tendency to stretch and push the telescopic member 5. Figure 4 In the embodiment, the elastic element 11 pushes the telescopic member 5, so that the telescopic member 5 keeps protruding from the first slider 2, so that the telescopic member 5 keeps plugging into the first slide rail 1, the sliding mechanism keeps locked, the first slider 2 keeps vertically supported on the first slide rail 1, and the table 3 keeps fixed in the height direction, thereby meeting the storage requirements. Figure 6 In order to make the first slider 2 slide vertically along the first slide rail 1, the control member 6 moves vertically to drive the telescopic member 5 to move horizontally. The telescopic member 5 further compresses the elastic element 11 under the drive of the control member 6, and the telescopic member 5 retracts the first slider 2, so that the telescopic member 5 withdraws from the first slide rail 1, and the telescopic member 5 is disconnected from the first slide rail 1. The first slider 2 can slide vertically along the first slide rail 1, and the sliding mechanism can slide to drive the table 3 to rise and fall vertically, thereby adjusting the vertical height of the table 3.

[0050] like Figures 4 to 6 As shown, in the embodiment where the lifting platform is provided with two sliding mechanisms, the elastic element 11 can be provided between the two telescopic members 5. The elastic element 11 is provided in the lateral middle of the two telescopic members 5. The elastic element 11 is compressed by the telescopic members 5 on both lateral sides and is always in a compressed state. The elastic element 11 always has a tendency to stretch and push the two telescopic members 5. Figure 4 In the embodiment, the elastic element 11 pushes against the two telescopic members 5, so that each telescopic member 5 keeps protruding from its respective first slider 2, each telescopic member 5 keeps plugging into its respective first slide rail 1, both sliding mechanisms keep locked, each first slider 2 keeps vertically supported on its respective first slide rail 1, and the table 3 keeps fixed in the height direction, thereby meeting the storage requirements. Figure 6 In order to make the first slider 2 slide vertically along the first slide rail 1, the control member 6 moves vertically to drive the two telescopic members 5 to move horizontally. The two telescopic members 5 further compress the elastic element 11 under the drive of the control member 6, and each telescopic member 5 retracts its own first slider 2, so that each telescopic member 5 withdraws from its own first slide rail 1, and each telescopic member 5 is disconnected from its own first slide rail 1. Each first slider 2 can slide vertically along its own first slide rail 1, and both sliding mechanisms can slide to drive the table 3 to rise and fall vertically, thereby adjusting the vertical height of the table 3. The elastic element 11 can be a coil spring.

[0051] like Figures 4 to 6 As shown, the control member 6 may be provided with a second slide rail 12, which extends obliquely between the horizontal and vertical directions, and the extension direction of the second slide rail 12 may be located in a plane formed by the horizontal and vertical directions, and is inclined at a certain angle relative to the horizontal and vertical directions. The telescopic member 5 may be provided with a second slider 13, which slides with the second slide rail 12, and the second slider 13 can be driven by the second slide rail 12 to slide in the second slide rail 12. The control member 6 moves vertically, driving the second slide rail 12 to move vertically, and the inclined second slide rail 12 applies a lateral force to the second slider 13, driving the second slider 13 to move horizontally, driving the telescopic member 5 to move horizontally, so that the control member 6 moves vertically to control the telescopic member 5 to move horizontally. The second slide rail 12 and the second slider 13 slide in cooperation to convert the vertical movement of the control member 6 into the lateral movement of the telescopic member 5, and the structure is simple and reliable. In an embodiment where two sliding mechanisms are provided on the lifting platform, each telescopic member 5 is provided with a second slider 13 , and a control member 6 is provided with two second slide rails 12 to respectively slideably cooperate with the second sliders 13 of the two telescopic members 5 , thereby controlling the lateral movement of the two telescopic members 5 .

[0052] like Figures 1 to 6 As shown, the sliding control mechanism 4 may further include a pipe 8, the pipe 8 extends in the transverse direction, the elastic element 11 and the telescopic member 5 are arranged in the pipe 8, the pipe 8 guides the telescopic member 5 to slide in the transverse direction, the pipe 8 and the telescopic member 5 slide in cooperation, and the telescopic member 5 is restricted by the pipe 8 and slides in the transverse direction along the pipe 8. In the embodiment where the lifting platform is provided with two sliding mechanisms, the pipe 8 connects the two first sliding blocks 2, the elastic element 11 and the two telescopic members 5 are arranged in the pipe 8, and the pipe 8 guides the two telescopic members 5 to slide in the transverse direction.

[0053] like Figures 2 to 4 as well as Figure 6 As shown, the first slider 2 may be provided with a second opening 14 to allow the telescopic member 5 to protrude from and retract into the first slider 2. The second opening 14 may be provided on the lateral side wall of the first slider 2. The telescopic member 5 moves laterally to extend from the second opening 14 so as to protrude from the first slider 2. The telescopic member 5 moves laterally to retract into the second opening 14 so as to retract into the first slider 2.

[0054] like Figures 4 to 6 As shown, the control member 6 can be sleeved on the outside of the pipe 8, and the second slider 13 protrudes from the pipe 8. The second slider 13 protrudes from the telescopic member 5 in the pipe 8 to the outside of the pipe 8, thereby plugging into the second slide rail 12 located on the outside of the pipe 8 to achieve sliding cooperation with the second slide rail 12, as shown in FIG. Figure 5As shown, the pipe 8 can be provided with a groove 15 to allow the second slider 13 to protrude. The second slider 13 extends from the groove 15 and thus protrudes from the pipe 8. The groove 15 extends in the transverse direction to avoid blocking the transverse movement of the second slider 13, thereby allowing the telescopic member 5 to move in the transverse direction. The structure is simple and reliable.

[0055] Compare Figure 4 and Figure 6 , the control member 6 can be set to move vertically upward to make the first slider 2 slide vertically along the first slide rail 1. The control member 6 moves vertically upward to make the telescopic member 5 move horizontally to retract the first slider 2, release the connection between the telescopic member 5 and the first slide rail 1, and the first slider 2 can slide vertically along the first slide rail 1, and the sliding mechanism can slide. The control member 6 can be lifted vertically upward to overcome gravity to release the lock of the sliding mechanism, adjust the vertical height of the table 3, ensure that the sliding mechanism remains locked normally, and the table 3 maintains a fixed vertical height normally, thereby ensuring the stability of the placed objects. Figure 1 , Figure 2 as well as Figures 4 to 6 As shown, the control member 6 can be provided with a handle 16, and the table 3 can be provided with a palm rest 17, which is located on the vertical upper side of the handle 16. The operator can place the palm on the palm rest 17, hook the fingers on the handle 16 and apply force upward, so as to facilitate vertically lifting the control member 6 upward, release the lock of the sliding mechanism, and adjust the vertical height of the table 3.
