Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tables, and in particular relates to a lifting table with a brushless motor. Background Art

[0002] A height-adjustable desk is a type of desk that is widely used and adopted in modern offices. It primarily adjusts the height of the desk surface to accommodate people of different heights. This allows for greater freedom in office work, in line with the current trend. Using a height-adjustable desk can effectively prevent spinal and cervical spondylosis, making it an indispensable tool, especially for those who want to maintain a good figure. However, existing height-adjustable desks can only be raised and lowered, not extended horizontally. This reduces the user's desk surface area, hindering practical use.

[0003] Existing patent documents disclose a utility model patent for an electric lift table (Announcement No.: CN221307557U). Its technical solution records that each lift table leg module includes an inner leg seat, an outer leg seat mounted on the inner leg seat, and an electric lift drive assembly. The lift drive assembly is used to change the height of the desktop, but the length of the lift table frame cannot be changed. The above-mentioned problem also exists. The lift table can only be adjusted up and down and cannot be expanded horizontally. The user's usage space is limited, which is not conducive to the user's actual use. Utility Model Content

[0004] The purpose of this utility model is to provide a technical solution for a lifting table with a brushless motor to address the shortcomings of the existing technology. The utility model has a sophisticated structural design and is easy to use. Users can adjust the length of the table frame according to actual conditions, and it is suitable for table tops of different lengths and sizes, expanding the scope of application. At the same time, users can also adjust the height according to their needs, which is convenient for users' actual use.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A lift table with a brushless motor includes a table frame and lift columns. The lift columns are arranged on both sides of the table frame and are connected to a drive mechanism. The table frame includes a crossbeam and a sleeve. Adjustable settings between the crossbeam and the sleeve allow the user to adjust the length of the table frame according to actual needs. This adjustable length table frame not only facilitates user adjustment based on space requirements but also improves the practicality of the lift table.

[0007] Furthermore, the sleeves are evenly provided with connection holes 1, and the crossbeams are evenly provided with connection holes 2. The connection holes 1 and 2 are connected by a connector to achieve the connection between the sleeves and the crossbeams. The depth of the crossbeam within the sleeves can be adjusted to adjust the length of the table frame. The precise alignment of the connection holes 1 and 2, as well as the secure connection via the connector, ensures the stability of the sleeves and crossbeams.

[0008] Furthermore, a placement plate is installed on the top of the lifting column to connect the top of the lifting column to the table top. The placement plate is fixed to the lifting column with screws. The placement plate has perforations on the side, and the lifting column is provided with lead holes. The perforations and lead holes are arranged in a corresponding manner. The arrangement of the perforations and lead holes facilitates the laying of wires in the lifting column and the extraction of cables.

[0009] Furthermore, the drive mechanism includes a driver and a connecting rod. The driver is mounted on one of the lifting columns, and the connecting rod is connected between the two lifting columns. The connecting rod is connected to the driver, and the driver drives the synchronous raising and lowering of the two lifting columns through the connecting rod. Users can choose the installation location of the driver according to their needs, which provides high flexibility. The driver generally uses a brushless motor. Using a brushless motor as the driver of the electric lifting table can meet the requirements of high speed and high load capacity. Users only need to operate it simply to achieve smooth raising and lowering of the desktop, meeting the needs of different heights and sitting postures.

[0010] Furthermore, the connecting rod comprises a sleeve rod, a first link, and a second link. Links 1 and 2 are located at either end of the sleeve rod and are respectively connected to the two lifting columns. The combined design of the sleeve rod, first link, and second link increases overall rigidity, ensuring greater stability and resistance to deformation during the lifting process.

[0011] Furthermore, a polygonal through-hole is provided through the sleeve rod, and connecting rod 1 and connecting rod 2 are matched and inserted into the polygonal through-hole, and connecting rod 1 and connecting rod 2 are fixed to the sleeve rod by limiting bolts. Both ends of the sleeve rod are provided with fixing holes, and the limiting bolts pass through the fixing holes and are tightly fixed to connecting rod 1 and connecting rod 2 inserted into the polygonal through-hole, thereby ensuring the overall structural stability of the connecting rod. Corresponding to the design of the polygonal through-hole, connecting rod 1 and connecting rod 2 are also polygonal structures, thereby improving the plug-in stability and reliability, and avoiding loose or misaligned connections. At the same time, the installation method of limiting and fixing with limiting bolts can also facilitate the adjustment of the length of connecting rod 1 inserted into the polygonal through-hole, so that the overall length of the connecting rod is adjustable to adapt to the actual length of the table frame, thereby enabling installation between table tops of different lengths.

[0012] Furthermore, the ends of connecting rod 1 and connecting rod 2 inserted into the polygonal through-hole are both provided with tapered plugs, and the tapered plug on connecting rod 1 is provided with a placement slot. The tapered plug design facilitates the insertion and installation of connecting rods 1 and 2 into the sleeve rod, while the placement slot facilitates the placement of components such as the installation sleeve, thereby facilitating the smooth sliding of connecting rod 1 within the polygonal through-hole and allowing adjustment of the connecting rod length.

[0013] Furthermore, the lifting column is provided with a back plate with mounting hole 1, which is correspondingly provided with mounting hole 2 on the table frame. Mounting hole 1 and mounting hole 2 are connected to achieve the connection between the lifting column and the table frame. The corresponding arrangement of mounting hole 1 and mounting hole 2 ensures the precise connection between the lifting column and the table frame, improving the structural stability of the lifting table. The back plate increases the contact area between the lifting column and the table frame, thereby increasing the load-bearing capacity.

[0014] Furthermore, a connecting block is provided on the crossbeam, and a connecting hole 3 is provided on the connecting block, which is convenient for connecting with the table board and improving the connection firmness between the table board and the table frame.

[0015] Furthermore, the bottom of the lifting column is equipped with a support foot, which is equipped with an elastic pad at the bottom. The end of the support foot is tilted. The support foot can significantly enhance the load-bearing capacity of the lifting column. The elastic pad can absorb and reduce the vibration and impact generated by the lifting column during the lifting process. The end of the support foot is tilted to prevent users from bumping into the support foot.

[0016] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0017] The utility model can be adjusted laterally and can also be adjusted up and down, which greatly improves the convenience of use for users. Users can adjust the horizontal length of the table frame and the height of the lifting table according to actual conditions. Users only need to perform simple operations to achieve smooth lifting of the desktop to meet the needs of different heights and sitting postures. The overall installation and operation are convenient, which reduces the labor intensity of the staff. The installation is firm, the lifting is smooth, and the user is comfortable to use.

DETAILED DESCRIPTION

[0027] like Figures 1 to 7 The figure shows a lift table with a brushless motor according to the present invention, comprising a table frame 1 and lift columns 2. The lift columns 2 are arranged on both sides of the table frame 1 and connected to a drive mechanism 3. The table frame 1 includes a crossbeam 4 and a sleeve 5. The crossbeam 4 and the sleeve 5 are adjustable to adjust the length of the table frame 1. The adjustment device between the crossbeam 4 and the sleeve 5 allows the user to adjust the length of the table frame 1 according to actual needs. The adjustable length of the table frame 1 not only facilitates user adjustment based on the size of the space, but also improves the practicality of the lift table.

[0028] The sleeve 5 is evenly provided with connection holes 1 6, and the crossbeam 4 is evenly provided with connection holes 2 7. The connection holes 1 6 and 2 7 are connected by a connector 8, thereby connecting the sleeve 5 to the crossbeam 4. The depth of the crossbeam 4 in the sleeve 5 is adjusted to adjust the length of the table frame 1. The provision of multiple connection holes 1 6 and 2 7 facilitates the user to adjust the table frame 1 according to different needs. The fastening connection of the connector 8 ensures the stability between the sleeve 5 and the crossbeam 4. The connector 8 is fixed with screws, which is convenient to operate. The outer side of the crossbeam 4 is tightly fitted with the inner wall of the sleeve 5, and there is a gap between the other surfaces of the crossbeam 4 and the sleeve 5, which facilitates the laying of cables.

[0029] A placement plate 9 is provided on the top of the lifting column 2, which allows for the connection between the top of the lifting column 2 and the tabletop. The placement plate 9 is screwed to the lifting column 2 to ensure secure installation. A perforation 10 is provided on the side of the placement plate 9, and a lead-in hole 11 is provided on the lifting column 2. The perforations 10 and lead-in holes 11 are arranged in a corresponding manner. The arrangement of perforations 10 and lead-in holes 11 facilitates the laying and routing of wires in the lifting column 2, avoids the clutter of cables, facilitates cable management, and improves the cleanliness and aesthetics of the working environment.

[0030] The driving mechanism 3 includes a driving member 28 and a connecting rod 29. The driving member 28 is provided on one of the lifting columns 2. The connecting rod 29 is connected between the two lifting columns 2. The connecting rod 29 is connected to the driving member 28. The driving member 28 drives the synchronous lifting and lowering of the two lifting columns through the connecting rod 29. The user can select the installation position of the driving member 28 according to the needs, which is highly flexible. The driving member 28 generally adopts a brushless motor. Using a brushless motor as the driving member 28 of the lifting table can meet the requirements of the electric lifting table for high speed and large load-bearing capacity. The user only needs to perform simple operations to achieve the smooth lifting and lowering of the desktop to meet the needs of different heights and sitting postures. The connecting rod 29 cooperates with the table frame 1 to enable the two lifting columns 2 to be raised and lowered synchronously, ensuring the stability and stability of the desktop.

[0031] Connecting rod 29 comprises a sleeve rod 14, a first connecting rod 15, and a second connecting rod 16. These connecting rods 15 and 16 are located at either end of sleeve rod 14, and are respectively connected to the two lifting columns. The combined design of sleeve rod 14, first connecting rod 15, and second connecting rod 16 increases overall rigidity, ensuring the table maintains greater stability and resistance to deformation during the lifting process. First connecting rod 15 connects to one lifting column 2, while second connecting rod 16 connects to the other lifting column 2. This ensures synchronization between the two lifting columns 2 during the lifting process, further improving the stability and transmission efficiency of the table.

[0032] A polygonal through-hole is provided through the sleeve rod 14, and the connecting rod 15 and the connecting rod 2 16 are matched and inserted into the polygonal through-hole. The connecting rod 15 and the connecting rod 2 16 are fixed to the sleeve rod by a limit bolt 18. Both ends of the sleeve rod 14 are provided with fixing holes. The limit bolt 18 passes through the fixing holes and is tightly fixed to the connecting rod 15 and the connecting rod 2 16 inserted into the polygonal through-hole, ensuring the overall structural stability of the connecting rod 29. Corresponding to the design of the polygonal through-hole, the connecting rod 15 and the connecting rod 2 16 also have a polygonal structure, thereby improving the plug-in stability and reliability and avoiding loose or misaligned connections. At the same time, the installation method of the limit bolt 18 can also facilitate the adjustment of the length of the connecting rod 15 inserted into the polygonal through-hole, so that the overall length of the connecting rod 29 is adjustable to adapt to the actual length of the table frame 1, thereby enabling installation between table tops of different lengths.

[0033] The ends of connecting rod 15 and connecting rod 2 inserted into the polygonal through-hole are both provided with tapered plug portions 19, and tapered plug portions 19 of connecting rod 15 are provided with placement slots 20. The design of tapered plug portions 19 facilitates the insertion and installation of connecting rods 15 and 16 with sleeve rod 14, while placement slots 20 facilitate the placement of components such as the installation sleeve, thereby facilitating the smooth sliding of connecting rod 15 within the polygonal through-hole and facilitating the adjustment of the length of connecting rod 29.

[0034] The lifting column 2 is provided with a back plate 21, and the back plate 21 is provided with a mounting hole 1 22. The table frame 1 is correspondingly provided with a mounting hole 2 23. The mounting hole 1 22 is connected to the mounting hole 2 23 to achieve the connection between the lifting column 2 and the table frame 1. The corresponding arrangement of the mounting hole 1 22 and the mounting hole 2 23 ensures the precise docking between the lifting column 2 and the table frame 1, reduces the shaking or tilting caused by the loose connection, and thus improves the structural stability of the entire lifting table. The back plate 21 increases the contact area between the lifting column 2 and the table frame 1, increasing the load-bearing capacity. The crossbeam 4 is provided with a connecting block 24, and the connecting block 24 is provided with a connecting hole 3 25. This facilitates the connection with the table top and improves the connection strength between the table top and the table frame 1.

[0035] The bottom of the lifting column 2 is provided with a support foot 26, and the bottom of the support foot 26 is provided with an elastic pad 27. The end of the support foot 26 is set at an angle. The support foot 26 can significantly enhance the load-bearing capacity of the lifting column 2, making the entire lifting table more stable when carrying heavy objects. The elastic pad 27 can absorb and reduce the vibration and impact generated by the lifting column 2 during the lifting process, reducing the impact of noise and vibration on the surrounding environment and users, improving the overall placement and use stability of the lifting table, and also preventing the bottom of the lifting column 2 from directly contacting the ground, extending the service life of the lifting column 2. The end of the support foot 26 is set at an angle to prevent the user from bumping into the support foot 26 when using the lifting table, which may cause harm to the user. It also hides the elastic pad 27, improving the aesthetics.

[0036] The utility model can be adjusted laterally and can also be adjusted up and down, which greatly improves the convenience of use for users. Users can adjust the horizontal length of the table frame and the height of the lifting table according to actual conditions. Users only need to perform simple operations to achieve smooth lifting of the desktop to meet the needs of different heights and sitting postures. The overall installation and operation are convenient, which reduces the labor intensity of the staff. The installation is firm, the lifting is smooth, and the user is comfortable to use.

[0037] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications based on the present invention to achieve substantially the same technical effects are included within the scope of protection of the present invention.
