This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0027] See also Figure 1 , 2, 3, 4, 5, and 6 are schematic diagrams of preferred embodiments of the present invention. The present invention is related to a lifting table, which has a support column 1, a lifting module 2, a stopper 3, a hand control 4, a mounting module 5, and a table top 6. In this embodiment, a support column 1 is used to construct a support system, and a bottom plate 13 is provided at the lower end of the support column 1 to increase the ground contact area and improve the standing stability of the support column 1. The lifting module 2 is installed on the support column 1 through a lifting guide structure and supported by a suspension system. In this embodiment, the preferred lifting guide structure is a linear guide rail 9. The left and right sides of the lifting module 2 are installed on the support column 1 through the linear guide rail 9, and the linear guide rail 9 guides the lifting and lowering movement of the lifting module 2. The suspension system supports the lifting module 2 so that the lifting module 2 is relatively at a set height and has an adjustment feature. The height position of the lifting module 2 can be adjusted by overcoming the supporting force of the suspension system. The suspension system includes a telescopic elastic body 71, a pulley 72 and a hoisting line 73. The telescopic elastic body 71 is positioned on the support column 1 and elastically supports the pulley 72, so that the pulley 72 can be lifted and floated. The hoisting line 73 spans the pulley 72 and hoists the lifting module 2, so that the lifting module 2 can move along the set direction of the support column 1. In this embodiment, the telescopic elastic body 71 is a cylinder erected from bottom to top, the upper end of the telescopic elastic body 71 is a movable end and is installed with the pulley 72, the hoisting line 73 can be a rope or a steel wire, etc., the middle section of the hoisting line 73 spans the pulley 72 and uses the pulley principle to adjust the balance of the two ends, and the two ends of the hoisting line 73 are connected to the lifting module 2 to realize the lifting assembly of the lifting module 2. By extending the telescopic elastic body 71, the pulley 72 is lifted and the lifting module 2 is pulled to a certain height position through the hoisting line 73, and the original height can be obtained at this time. In this embodiment, a cylinder is used as an example, but it is not limited to this. The telescopic elastic body 71 can also be a structure such as a compression spring. When installing, the telescopic elastic body 71 does not exclude the hanging form, as long as the lifting module 2 is suspended.

[0028] The stopper 3 is installed on the lifting module 2, and the lifting movement of the lifting module 2 is limited by the connection between the stopper 3 and the supporting column 1, so as to stabilize the lifting module 2 and obtain implementation situations of different heights. The hand control 4 is connected to the stopper 3 so as to manually operate to release the stop state of the stopper 3, so that the suspension posture of the lifting module 2 can be restored, and the height of the lifting module 2 can be adjusted, which eliminates the need to remove the positioning screws and other processes, and is easier to operate. The installation module 5 is installed on the lifting module 2 and connected to the corresponding table board 6, so that the table board 6 can follow the lifting module 2 to perform lifting movement, that is, to achieve the lifting and lowering adjustment of the table board, and obtain desktops of different heights for work or study. In this embodiment, the table board 6 can be designed as a single board or a multi-layer multi-board form as needed to meet the needs.

[0029] The lifting module 2 of the utility model can be lifted up and down along the supporting column 1, that is, the table top 6 can be adjusted in height up and down along the supporting column 1, and the suspension system provides support so that the table top 6 can obtain the corresponding original height, and with the restriction of the stopper 3, a stable desktop height can be obtained; when the hand control unit 4 releases the stopping state of the stopper 3, the user can pull up or press down the table top 6 to adjust the height, and after adjustment, the stopper 3 enters the stopping state again, thereby limiting the lifting module 2, and providing support with the suspension system to keep the table top 6 stable to meet the needs, and the operation is repeated in this way, and the use height of the desktop can be adjusted according to personal needs.

[0030] Figure 1 , 2 As shown in , 3, 4, 5, and 6, in this embodiment, the support column 1 is a hollow column formed by the front cover 11 and the rear cover 12, which is convenient for manufacturing and assembly, and is conducive to the positioning of the lifting module 2 and the suspension system inside the support column 1 and obtaining protection, and the overall appearance is beautiful and generous. In this embodiment, a part of the lifting module 2 extends from the rear cover 12 of the support column 1 and forms a mounting portion 21, and the mounting portion 21 is used to connect the stopper 3 and the mounting module 5. The mounting module 5 is preferably a symmetrical structure, which is screwed to the mounting portion 21 and symmetrically installed based on the support column 1. The mounting module 5 is in a horizontal V-shape, and the arms extending forward from the rear side of the support column 1 are used to connect the table board 6 and form a lifting shape. The structure is simple, convenient for installation and assembly, and a stable connection relationship is obtained. The table board 6 is located on the front side of the support column 1 and is built around the support column 1, which also obtains a better product geometric center of gravity, and the support and lifting are relatively more stable. A lifting avoidance groove 121 and a lifting positioning tooth groove 122 are provided on the rear cover 12. The lifting avoidance groove 121 is adapted to the partial extension and lifting avoidance of the lifting module 2, and the lifting positioning tooth groove 122 is designed to be spaced along the lifting direction of the lifting module 2. The lifting positioning tooth groove 122 cooperates with the stopper 3 to limit the lifting movement of the lifting module 2.

[0031] like Figure 3 , 4 As shown, the lifting module 2 is formed by the combination of two inner and outer parts, which are designed as U-shaped blocks. The inner part is installed on the supporting column 1 through the linear guide rail 9 and has two side arms extending through the lifting avoidance groove 121, and then is fixedly connected with the outer part by screws or the like to form a whole. The inner side of the outer part is assembled with the stopper 3, and the outer side of the outer part is assembled with the mounting module 5, which has a compact and reasonable structure and is convenient for assembly implementation.

[0032] In this embodiment, the stopper 3 is an L-shaped structure, and the vertical end of the stopper 3 is connected to the mounting portion 21 in a hinged manner, so that the horizontal folded end of the stopper 3 forms a pendulum posture, and the horizontal folded end of the stopper 3 is connected to the locking spring 8 and the hand control 4; one end of the locking spring 8 is positioned on the mounting portion 21, and the other end of the locking spring 8 is connected to the stopper 3, and the stopper 3 is pulled by the locking spring 8, so that the horizontal folded end of the stopper 3 remains locked in the lifting positioning tooth groove 122, thereby limiting the movement of the lifting module 2. The hand control 4 drives the stopper 3, so that the horizontal folded end of the stopper 3 exits the lifting positioning tooth groove 122, and the lifting module 2 can be lifted and lowered. Furthermore, in this embodiment, the stop member 3 moves on one side of the lifting positioning tooth groove 122, and a limiting rib 123 is also provided on the back cover 12, and the limiting rib 123 extends along the lifting direction of the lifting module 2 and faces the notch of the lifting positioning tooth groove 122; the limiting rib 123 is used to limit the swing amplitude of the stop member 3 when the hand control unit 4 drives the stop member 3, to prevent the stop member 3 from swinging excessively, and also facilitates the subsequent insertion into the lifting positioning tooth groove 122, thereby improving practicality. Figure 4 As shown, in this embodiment, the vertical portion of the stopper 3 is constructed into a Y-shape with two arms, and the transverse folded portion of the stopper 3 is a pin shaft and has two Y-shaped arms. This structural design facilitates the connection of the locking spring 8 and the hand control unit 4, and can ensure stable and reliable operation.

[0033] In this embodiment, the hand control 4 includes a pull wire 41 and a wrench 42. One end of the pull wire 41 is connected to the stopper 3, and the other end of the pull wire 41 is connected to the wrench 42. The wrench 42 is installed on the lower side of the table 6 and can rotate relatively. The pull wire 41 is pulled by rotating the wrench 42, so that the pull wire drives the stopper 3 to swing, and the horizontal folded end of the stopper 3 exits the lifting and positioning tooth groove 122, thereby releasing the stopper 3 from the stopped state. This structure can realize the operation of the wrench 42 while pulling up or pressing down the table 6, which is convenient to operate; when the pull wire drives the stopper 3 to swing, the locking spring 8 is pulled and stored, so that when the wrench 42 is released later, the locking spring 8 pulls back the stopper 3, so that the horizontal folded end of the stopper 3 remains stuck in the lifting and positioning tooth groove 122, limiting the movement of the lifting module 2. Such cooperation has a simple and reasonable structure, meets the lifting and adjustment of the table, and is also easy to operate.

[0034] The utility model supports the lifting module through the suspension system, does not need power supply to work, is not restricted in the place of use, and is equipped with a stopper to limit the lifting movement of the lifting module, and the height positioning is stable; when adjusting, the stopper can be released by manually operating the hand control, which is convenient for adjustment and reduces the process of removing screws. The overall structure of the utility model is compact and reasonable, occupies a small space, is built around the supporting column and can be lifted in a straight line, and there will be no adjustment failure. The height adjustment effect is good, which improves the user experience.

[0035] Although the preferred specific embodiments of the present invention are described above in conjunction with the accompanying drawings, the present invention should not be limited to the structures and operations that are exactly the same as the above description and the accompanying drawings. For those skilled in the art, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and changes should all fall within the scope of protection required by the present invention.
