[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] See also Figures 1-4 The lifting platform 3 is a kind of lifting platform 3 that is convenient to adjust, and its lifting height is greatly improved.

[0027] In this embodiment: the four corners of the top surface of the installation base plate 2 are longitudinally connected with positioning sleeves 10, and the four corners of the bottom surface of the lifting work station plate 3 are welded with positioning extension rods 12, which are longitudinally lifted and lowered in the inner cavity of the positioning sleeve 10 for positioning.

[0028] Specifically, the travel slot 7 provides a track for linear motion for the articulated slider 8, limits the direction of motion of the articulated slider 8, ensures linearity, and ensures the smoothness and precision of the motion. The push-pull articulated rod 9 connects the articulated slider 8 and the lifting station plate 3, converts the movement of the articulated slider 8 into the lifting of the lifting station plate 3, and enables the lifting station plate 3 to be lifted and lowered smoothly to reach the desired height. The positioning sleeve 10 provides guidance and positioning for the positioning extension rod 12, ensuring the linearity of the lifting station plate 3 during the lifting process, and improving the accuracy and stability of the station plate movement. The positioning extension rod 12 connects the lifting station plate 3 and the mounting base plate 2, providing additional vertical guidance for the lifting station plate 3, improving the stability and vertical accuracy during lifting.

[0029] In this embodiment: a buffer and shock-absorbing assembly is arranged between the mounting base plate 2 and the lifting work station plate 3, and the top buffer end of the buffer and shock-absorbing assembly elastically abuts against the bottom surface of the lifting work station plate 3. Two mounting holes 14 are symmetrically opened on the top surface of the mounting base plate 2. The buffer and shock-absorbing assembly includes a hydraulic damper 15 respectively installed in the mounting hole members 14 and a compression spring 16 arranged on the side of the hydraulic damper 15 in the mounting hole members 14. The top ends of the hydraulic damper 15 and the compression spring 16 abut against the bottom surface of the lifting work station plate 3.

[0030] Specifically, the hydraulic damper 15 absorbs the impact force generated during lifting, slowing the movement of the lifting workstation 3 and improving the safety and comfort of the mechanism during operation. The compression spring 16 assists the hydraulic damper 15 in providing a buffering effect, helping to absorb vibration and impact, improving the stability of the system and extending its service life.

[0031] In this embodiment, both inner walls of each travel slide 7 are provided with positioning extension grooves 17 , and both outer walls of each hinged slider 8 are provided with positioning extension blocks 18 that slide in cooperation with the positioning extension grooves 17 .

[0032] Specifically, the articulated slider 8 slides in the travel chute 7, transmitting the force of pushing and pulling the articulated rod 9, converting the linear motion into rotation or swinging of the push-pull articulated rod 9, thereby achieving the lifting and lowering action of the liftable workstation 3. The positioning extension block 18 cooperates with the positioning extension groove 17 on the travel chute 7 to prevent the articulated slider 8 from moving laterally during movement, ensuring the accuracy of the linear sliding of the articulated slider 8.

[0033] In this embodiment, a hinged fixed block 20 is symmetrically welded to the bottom surface of the lifting work station plate 3 , and the top end of each push-pull hinged rod 9 is hinged to the hinged fixed block 20 through a hinge pin 13 .

[0034] Specifically, the hinged fixing block 20 is used for the hinged installation of the top end of the push-pull hinged rod 9, allowing relative rotation between the push-pull hinged rod 9 and the lifting station plate 3, ensuring a reliable connection between the push-pull hinged rod 9 and the lifting station plate 3.

[0035] In this embodiment, two hinged sliders 8 are provided with hinge grooves 19 on opposite sides thereof for hinged installation of the bottom ends of the push-pull hinged rods 9 .

[0036] Specifically, the hinge groove 19 is used for the hinged installation of the bottom end of the push-pull hinge rod 9, allowing relative rotation between the push-pull hinge rod 9 and the hinge slider 8, ensuring reliable connection and flexible movement of the push-pull hinge rod 9.

[0037] In this embodiment, the two travel slides 7 are both provided with an open structure at one end thereof for the hinged slider 8 to slide out, and a detachable end plate 5 is mounted on each open structure by bolts, and the cylinder member 6 is fixedly mounted on the outer wall of the detachable end plate 5, and the lower part of the outer wall on both sides of the mounting base member 2 is integrally connected with the mounting side plate 4.

[0038] Specifically, the detachable end plate 5 closes the open structure of the travel slide 7, which facilitates maintenance and replacement of internal components, improves safety, and simplifies the maintenance process.

[0039] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0040] The working principle and usage process of the utility model: When using this mechanism that is convenient for adjusting the work station height, the base plate 2 is installed and fixed at the position of the required equipment. The lifting work station plate 3 is connected to the articulated slider 8 by pushing and pulling the articulated rod 9. The articulated slider 8 slides in the travel slide 7. The cylinder part 6 is fixedly installed on the detachable end plate 5, and its piston rod 11 is fixedly connected to the articulated slider 8.

[0041] When the height of the work station needs to be adjusted, the operator starts the oil cylinder 6, and the piston rod 11 of the oil cylinder 6 begins to extend or retract. When the piston rod 11 extends, it pushes the articulated slider 8 to slide forward along the travel slot 7. The movement of the articulated slider 8 is transmitted to the lifting station plate 3 through the push-pull articulated rod 9. The push-pull articulated rod 9 changes the angle as the articulated slider 8 moves, thereby transmitting the force to the lifting station plate 3 to make it rise. Conversely, when the piston rod 11 retracts, the articulated slider 8 slides backward along the travel slot 7. The change in the angle of the push-pull articulated rod 9 causes the lifting station plate 3 to descend. The four corners of the bottom surface of the lifting station plate 3 are welded with positioning extension rods 12. These positioning rods The position extension rod 12 is longitudinally lifted and positioned in the positioning sleeve 10 on the top surface of the installation base plate 2 to ensure the vertical movement of the lifting work station plate 3. Positioning extension grooves 17 are provided on the inner walls of both sides of the travel slide 7, and positioning extension blocks 18 are provided on the outer walls of both sides of the articulated slider 8. The two cooperate to ensure the stable sliding of the articulated slider 8 in the travel slide 7. A hinge groove 19 is provided on the opposite side of the articulated slider 8. The bottom end of the push-pull articulated rod 9 is hinged to the articulated groove 19 through the articulation pin 13, and the top end of the push-pull articulated rod 9 is articulated to the articulated fixing block 20 on the bottom surface of the lifting work station plate 3 through the articulation pin 13 to ensure a stable connection between the articulated slider 8 and the lifting work station plate 3.

[0042] Mounting holes 14 are provided on both sides of the top surface of the mounting base plate 2, in which a buffer shock-absorbing assembly consisting of a hydraulic damper 15 and a compression spring 16 is installed. The top ends of the hydraulic damper 15 and the compression spring 16 are in contact with the bottom surface of the lifting station plate 3, which is used to absorb the impact force and vibration generated during the lifting process to ensure the smooth movement of the lifting station plate 3. Mounting side plates 4 are provided on the lower parts of the outer walls on both sides of the mounting base plate 2 to enhance the structural strength of the entire mechanism. The detachable end plate 5 is installed on the open mouth structure of the travel slide 7 by bolts, which not only plays a sealing role, but also enhances the stability of the mechanism. The cylinder member 6 is fixedly installed on the detachable end plate 5 to ensure the stability and reliability of the cylinder member 6.
