[0033] The locking structure provided by this utility model can be installed not only on paperless conference lifts, but also on lifting tables, lifting screens, lifting partitions and other lifting machines.

[0034] This utility model provides a locking structure that can lock the lifting device at any position through the locking part 2. It has a simple structure and can improve the safety and convenience of maintenance.

[0035] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 4 As shown, the present invention provides a locking structure including a locking groove 1 provided on the inner side wall of the outer shell 3 and a locking part 2 provided on the lifting fixing plate 4. The locking part 2 includes a locking member 21 and a driving member 22. The locking member 21 has a locked state of being embedded in the locking groove 1 and an unlocked state of being disengaged from the locking groove 1.

[0037] The locking element 21 switches between a locked state and an unlocked state by driving the driving element 22 under the action of external force.

[0038] A typical paperless conference lift consists of a housing 3, a drive system, and an LCD screen. Both the drive system and the LCD screen are housed within the housing 3. The LCD screen is mounted on a lifting fixing plate 4 and moves up and down under the drive of the drive system. When applying the technical solution of this utility model to a paperless conference lift, both inner sidewalls of the housing 3 are provided with locking grooves 1, and both sides of the bottom of the lifting fixing plate 4 are equipped with locking parts 2. Under external force, the locking component 21 switches between locked and unlocked states via the driving component 22, ensuring that the lifting fixing plate 4 of the paperless conference lift can be stably fixed in any position on the housing 3, thus locking the LCD screen up and down. With this design, there is no need to lay the lift flat or disassemble it, which reduces the difficulty and complexity of maintenance and avoids accidental activation due to operational errors or equipment malfunctions.

[0039] Furthermore, the aforementioned locking element 21 includes a housing 210 and a locking pin 211;

[0040] The housing 210 is fixed on the lifting fixing plate 4, and the locking pin is embedded in the housing 210. The first end of the locking pin 211 is a pressing part, and the second end is used to embed into the locking groove 1.

[0041] The locking pin 211 is provided with a sliding groove 212, and a locking block 213 is provided in the sliding groove 212. The outer side wall of the locking block 213 and the inner side wall of the sliding groove 212 form a sliding track for moving the drive member 22. The end of the locking block 213 facing away from the locking groove 1 is provided with a recessed structure 213a.

[0042] The drive member 22 is disposed inside the housing 210. The drive member 22 includes a control rod 221 and a spring 222. The two ends of the control rod 221 are bent in the same direction to form a first hook and a second hook. The first hook is rotatably connected to the housing 210, and the second hook is located in the slide groove 212. The spring 222 is sleeved on the locking pin 211, and the two ends of the spring 222 abut against the housing 210 and the locking pin 211 respectively.

[0043] Furthermore, the slide groove 212 is provided with a guide block 214 on the inner sidewall facing the recessed structure 213a. The guide block 214 has a first inclined surface 214a and a second inclined surface. The first inclined surface 214a and the recessed structure 213a form part of the sliding track.

[0044] Furthermore, the guide block 214 is a triangular prism, with two sides of the prism facing the recessed structure 213a. One side of the prism forms part of the sliding track with the recessed structure 213a. During the pressing of the button shaft 211a, the second pawl of the control lever 221 moves in the slide groove 212 and enters the recessed structure 213a. When unlocking is required, the second pawl moves along the side of the triangular prism and disengages from the recessed structure 213a. Under the action of the spring 222, it moves along the sliding track to the rightmost end of the slide groove 212, and the locking lever disengages from the locking groove 1.

[0045] Furthermore, the aforementioned locking pin 211 includes a button shaft 211a and a locking rod 211b. The slide groove 212 is provided on the button shaft 211a. The button shaft 211a is provided with a mounting groove extending in the axial direction. The locking rod 211b is located in the mounting groove. The housing 210 is provided with a shaft hole for the locking rod 211b to pass through. The spring 222 is sleeved on the locking rod 211b.

[0046] Furthermore, the aforementioned locking groove 1 is a semi-cylindrical groove, and the axial direction of the semi-cylindrical groove is parallel to the horizontal plane.

[0047] Correspondingly, the end of the locking rod 211b facing the locking groove 1 has a hemispherical structure. The locking rod 211b cooperates with the semi-cylindrical groove of the locking groove 1, which can stably lock and fix the LCD screen.

[0048] Furthermore, the button shaft 211a is provided with a limiting block 211c extending along the axial direction, and the housing 210 is also provided with a limiting groove 210a for the limiting block 211c to be embedded in.

[0049] Furthermore, the above-mentioned locking structure also includes a mounting plate 11, which is provided with the locking groove 1 and is disposed on the inner side wall of the outer casing 3.

[0050] The locking mechanism provided by this utility model constructs a locking system for a paperless conference lift by designing a sliding track between the control rod 221 and the slide groove 212. The locking system achieves locking of the lift at any position through a spring 222, a movable control rod 221, a locking rod 211b that is pushed out, and a button shaft 211a for switching between locking and unlocking.

[0051] like Figure 3 As shown, in the initial state, the spring 222 is in a relaxed state, which can stably lock the second pawl of the control lever 221 at the rightmost end of the slide groove 212 (i.e., the direction close to the locking groove 1). Under this setting, it is ensured that the locking lever 211b can remain in the unlocked state without being subjected to external operation, so that it will not hinder the normal lifting and lowering operation of the paperless conference lift.

[0052] like Figure 4As shown, when maintenance or other work is required on the paperless conference lift, the user lightly touches the button shaft 211a and applies a certain amount of pressure. This action triggers the control lever 221 to begin sliding along the preset path of the slide groove 212. As the control lever 221 slides, the locking lever 211b will gradually emerge until the second claw of the control lever 221 engages with the recessed structure 213a of the locking block 213. Finally, the locking lever 211b is embedded in the locking groove 1 to achieve locking. Furthermore, the compression force of the spring 222 itself ensures that the control lever 221 can be locked on the recessed structure 213a, maintaining a locking strength between the locking lever 211b and the locking groove 1. When unlocking, the user only needs to press the button shaft 211a again. At this time, the spring 222 will release its stored energy and push the control lever 221 to slide along the first inclined surface 214a of the guide block 214, so that the second pawl of the control lever 221 disengages from the recessed structure 213a. At this time, the locking lever 211b gradually retracts until the control lever 221 returns to the rightmost position of the limit groove 210a, completing the entire cycle of the locking lever 211b being pushed out and retracted.

[0053] In this embodiment, the design not only cleverly utilizes the elastic potential energy of the spring 222, but also achieves stable sliding and locking of the control rod 221 in the slide groove 212 through structural optimization. Under this setting, not only is the reliability and durability of the locking rod 211b improved, but the lifting and locking operation of the paperless conference lift also becomes simple and convenient.

[0054] This embodiment also provides a paperless conference lift, which is equipped with a locking structure provided in this embodiment.

[0055] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
