Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The purpose of this invention is to provide a scissor lift platform to solve the problems existing in the prior art and improve the stability of the support.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] This embodiment provides a scissor lift platform; please refer to [link / reference]. Figures 1-3 The system includes a platform assembly 1, a scissor lift assembly 2, a drive assembly 3, and a telescopic assembly 4. The platform assembly 1 includes an upper platform 11 and a lower platform 12 arranged vertically at intervals. The scissor lift assembly 2 is disposed between the upper platform 11 and the lower platform 12. The scissor lift assembly 2 includes at least one pair of support arm mechanisms 21. Each support arm mechanism 21 includes two scissor lift arms 22 and 23 that are intersected around an intermediate shaft 24, and both the first scissor lift arms 22 and 23 are rotatably connected to the intermediate shaft 24.

The lower end is slidably connected to the upper surface of the lower platform 12, the upper end of the second scissor arm 23 is slidably connected to the lower surface of the upper platform 11, and the lower end of the second scissor arm 23 is rotatably connected to one side of the upper surface of the lower platform 12; the drive assembly 3 is disposed on the lower platform 12 and is drivenly connected to the lower end of the first scissor arm 22, and the drive assembly 3 can drive the lower end of the first scissor arm 22 to slide relative to the lower platform 12 so as to drive the upper platform 11 to rise and fall; one end of the telescopic assembly 4 is rotatably connected to the other side of the lower surface of the upper platform 11, and the other end is rotatably connected to the intermediate shaft 24, and the telescopic assembly 4 can adjust and fix its own length.

[0032] Supported by the upper platform 11 and the lower platform 12, the drive assembly 3 drives the lower end of the first scissor arm 22 to slide relative to the lower platform 12. Since the first scissor arm 22 and the second scissor arm 23 are rotatably connected to an intermediate shaft 24, the upper end of the first scissor arm 22 is rotatably connected to one side of the lower surface of the upper platform 11, and the upper end of the second scissor arm 23 is slidably connected to the lower surface of the upper platform 11. The lower end of the second scissor arm 23 is rotatably connected to one side of the upper surface of the lower platform 12. The sliding of the lower end of the first scissor arm 22 allows the first scissor arm 22 and the second scissor arm 23 to slide relative to the lower platform 12. The scissor arm 23 rotates around the intermediate shaft 24, driving the upper platform 11 to rise and fall. In addition, by setting the telescopic component 4, it can extend and retract along with the rise and fall of the upper platform 11, and can fix its own length for support. Since one end of the telescopic component 4 is supported on the side opposite to the upper surface of the upper platform 11 and the upper end of the first scissor arm 22, even if the upper end of the second scissor arm 23 is supported in the middle part of the upper platform 11, the telescopic component 4 and the first scissor arm 22 can still provide stable support for the upper platform 11. Thus, setting the telescopic component 4 can improve the overall stability.

[0033] More preferably, both the first scissor arm 22 and the second scissor arm 23 are provided with a turning section in the middle, and the turning section is rotatably connected to the intermediate shaft 24. Both the first scissor arm 22 and the second scissor arm 23 are S-shaped to ensure support stability.

[0034] In the optional embodiment, more preferably, the scissor lift assembly 2 includes two pairs of side-by-side support arm mechanisms 21, which are rotatably connected to both ends of the intermediate shaft 24 and symmetrically arranged about the central vertical section; the telescopic assembly 4 is disposed between the two sets of support arm mechanisms 21 for stable support; the drive assembly 3 is drivenly connected to the lower ends of the two first scissor lift arms 22; by setting two sets of support arm mechanisms 21, the overall support stability can be further improved, and the drive assembly 3 can drive the two first scissor lift arms 22 to slide synchronously so as to provide stable lifting and lowering support for the upper platform 11.

[0035] In the optional solutions of this embodiment, a more preferred option is described in the following description: Figure 1 The drive assembly 3 includes a linear drive mechanism 31 and a drive plate 32. The drive plate 32 is slidably connected to the upper surface of the lower platform 12, and the lower end of the first scissor arm 22 is rotatably connected to the drive plate 32. The linear drive mechanism 31 is disposed on the lower platform 12 and is connected to the drive plate 32 in a transmission manner. The linear drive mechanism 31 can drive the drive plate 32 to slide linearly relative to the lower platform 12 and drive the first scissor arm 22 to slide synchronously relative to the lower platform 12. By setting the drive plate 32, the lower ends of the two first scissor arms 22 can slide synchronously relative to the lower platform 12. Specifically, a connecting seat is provided on the drive plate 32, and the lower end of the first scissor arm 22 is hinged to the connecting seat by a pin to achieve a rotatable connection.

[0036] In the optional embodiments of this example, more preferably, the linear drive mechanism 31 is configured as a lead screw transmission mechanism. Specifically, the lead screw transmission mechanism includes a servo motor 33, a lead screw 34, a transmission seat 35, and a support seat 36. The servo motor 33 is connected to the lead screw via a reducer. One end of the lead screw 34 is connected to the reducer via a lead screw seat, and the other end is rotatably connected to the support seat 36. The lead screw 34 is rotatably connected to the lead screw seat and the support seat 36 via bearings. The lead screw 34 passes through the transmission seat 35 and is threadedly connected to it. The lead screw seat and the support seat 36 are fixedly connected to the lower platform 12 by screws. The transmission seat 35 is fixedly connected to the drive plate 32 by screws. The servo motor 33 drives the lead screw 34 to rotate so that the drive plate 32 can slide linearly via the transmission seat 35. In addition, it should be noted that the linear drive mechanism 31 is not limited to the above-mentioned lead screw transmission mechanism. Other structures can also be used, such as a telescopic motor, as long as linear drive can be achieved.

[0037] In the optional scheme of this embodiment, more preferably, the lower surface of the upper platform 11 and the upper surface of the lower platform 12 are both provided with slide rails 13. The upper end of the second scissor arm 23 is rotatably connected to a slider 14. The slider 14 is slidably connected to the slide rail 13 of the upper platform 11, and the drive plate 32 is slidably connected to the slide rail 13 of the lower platform 12. Specifically, the sliding fit between the slider 14 and the drive plate 32 and the slide rail 13 is an anti-disengagement fit. For example, the slide rail 13 is set as a C-shaped slide rail, and the slider 14 and the drive plate 32 are provided with C-shaped grooves to prevent disengagement while sliding. Other forms of fit can also be used, such as concave-convex sliding fit.

[0038] In the optional solutions of this embodiment, a more preferred option is described in the following description: Figures 4-7 The telescopic assembly 4 includes a connecting cylinder 41, a telescopic rod 42, and a locking element 43. One end of the connecting cylinder 41 is rotatably connected to the intermediate shaft 24. The telescopic rod 42 slides through the connecting cylinder 41, and one end of the telescopic rod 42 extending out of the connecting cylinder 41 is rotatably connected to the lower surface of the upper platform 11. The telescopic rod 42 has multiple locking positions 44 distributed along its length. The locking element 43 can pass through the wall of the connecting cylinder 41 and engage with a position to lock the relative position of the telescopic rod 42 and the connecting cylinder 41. By providing multiple locking positions 44, The position of the telescopic rod 42 can be locked by the locking member 43 according to the lifting height, so as to provide stable support. Specifically, one end of the telescopic rod 42 is rotatably connected to the upper platform 11 through the seat sleeve 46, the seat sleeve 46 is fixedly connected to the upper platform 11 by screws, and one end of the telescopic rod 42 is hinged to the seat sleeve 46 by a pin to achieve a rotatable connection. One end of the connecting cylinder 41 is rotatably sleeved on the intermediate shaft 24 through the sleeve, and the two ends of the intermediate shaft 24 can be rotatably connected to the first scissor arm 22 and the second scissor arm 23 through bearings.

[0039] In the optional embodiment, more preferably, the telescopic rod 42 has a plurality of connecting teeth 45 distributed along its length, and the locking position 44 is between adjacent connecting teeth 45; the locking member 43 is a locking pin, the connecting tube 41 is provided with an insertion hole, the locking pin is provided at the insertion hole and can be detachably connected to the tube wall of the connecting tube 41, and the inner end of the locking pin can extend into the locking position 44; wherein, the inner end of the locking pin is provided as a pointed tip, which can be inserted between the connecting teeth 45 for fixation.

[0040] More preferably, the locking pin can be inserted into the connecting cylinder 41. When it is necessary to fix the telescopic rod 42, the locking pin is inserted into the connecting cylinder 41 and cooperates with the locking position 44.

[0041] More preferably, the locking member 43 can be connected to the connecting cylinder 41 via an elastic component such as a spring. That is, the locking member 43 is slidably connected to the side wall of the connecting cylinder 41, i.e., it passes through the insertion hole. An elastic component is provided between the locking member 43 and the connecting cylinder 41. One end of the elastic component is fixedly connected to the locking member 43, and the other end is fixedly connected to the connecting cylinder 41. The locking member 43 can be pressed into the locking position 44 under the elastic force of the elastic component. The side of each connecting tooth 45 of the telescopic rod 42 near the upper platform 11 is a cut-off surface, and the side away from the upper platform 11 is a slope surface. Thus, when the telescopic rod 42 is relative to the connecting cylinder 41, the locking member 43 can be pressed into the locking position 44. When the connecting tube 41 slides outward and extends, the locking member 43 can move along the slope to the next locking position 44. During the movement along the slope, the elastic member pushes the locking member 43 outward to stretch the elastic member. When it reaches the next locking position 44, it automatically abuts and fixes the length under the restoring force of the elastic member, thus realizing the automatic locking of the locking member 43. When it is necessary for the telescopic rod 42 to slide inward and shorten relative to the connecting tube 41, the locking member 43 can be moved away from the locking position 44 by external force or the locking member 43 can be removed. The cut-off surface is set as a plane along the radial direction of the telescopic rod 42.

[0042] In the optional scheme of this embodiment, more preferably, the scissor lift platform provided in this embodiment also includes a walking component 5, which is disposed on the bottom side of the lower platform 12 to meet the walking requirements.

[0043] In the optional embodiments of this example, more preferably, the walking component 5 includes a plurality of walking wheels 51 disposed on the bottom side of the lower platform 12, and at least one walking wheel 51 is configured as a locking wheel. By configuring at least one walking wheel 51 as a conventional locking wheel, the overall position can be fixed. More preferably, four walking wheels 51 are configured and evenly distributed around the circumference, and two diagonally opposite or adjacent walking wheels 51 can be configured as locking wheels.

[0044] In the optional solutions of this embodiment, it is more preferred that the platform component 1, the scissor component 2 and the telescopic component 4 are all made of metal, such as stainless steel, which can meet the strength requirements.

[0045] The method of using the scissor lift platform provided in this embodiment is as follows:

[0046] When the upper platform 11 needs to rise, the lower ends of each first scissor arm 22 are driven by the drive assembly 3 to slide inward synchronously relative to the lower platform 12. Since the first scissor arms 22 and 23 are rotatably connected to an intermediate shaft 24, the upper ends of the first scissor arms 22 are rotatably connected to one side of the lower surface of the upper platform 11, and the upper ends of the second scissor arms 23 are slidably connected to the lower surface of the upper platform 11, while the lower ends of the second scissor arms 23 are rotatably connected to one side of the upper surface of the lower platform 12. The sliding of the lower ends of the first scissor arms 22 allows the first scissor arms 22 and 23 to rotate around the intermediate shaft 24, gradually bringing the first scissor arms 22 and 23 closer together, thereby driving the upper platform 11 to rise. Furthermore, the telescopic rod 42 of the telescopic assembly 4 can extend relative to the connecting cylinder 41 as the upper platform 11 rises, and the position of the telescopic rod 42 is fixed by the locking member 43 to fix its length for support. Since one end of the telescopic rod 42 is supported on the side opposite to the upper end of the first scissor arm 22 on the lower surface of the upper platform 11, even if the upper end of the second scissor arm 23 is supported in the middle part of the upper platform 11, the telescopic assembly 4 and the first scissor arm 22 can still provide stable support for the upper platform 11, thereby improving the overall stability of the telescopic assembly 4. When the upper platform 11 needs to be lowered, the lower end of each first scissor arm 22 can be driven to slide outward in a straight line synchronously relative to the lower platform 12 by the drive assembly 3.

[0047] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
