Description

TECHNICAL FIELD

[0001] The application relates to the technical field of push rod motors, in particular to a stroke column lifting structure of a push rod motor. BACKGROUND

[0002] As a height-adjustable office table, the lifting table is gradually favored by the market. The lifting table can adjust the height according to different work requirements and personal height, and provide a more comfortable and healthy office environment for users. The push rod motor is one of the key technologies for realizing height adjustment of the lifting table.

[0003] The stroke column lifting structure is the core component of the lifting table for realizing height adjustment. It is usually composed of an electric push rod (i.e. a push rod motor), a column and other parts. Through the driving of the motor, the rotary motion is converted into linear motion, thereby pushing the desktop of the lifting table to move up and down.

[0004] For example, the patent with publication number CN216494063U discloses an electric push rod for a lifting table. The patent sets a lead screw guide sleeve at one end close to the driving assembly, and sets a screw sleeve at the other end of the lead screw. The screw sleeve is fixedly connected to the other end of the lead screw through a screw. The setting of the lead screw guide sleeve plays a guiding role in the rotation of the lead screw, avoiding the deflection of the lead screw during rotation, thereby improving the precision of the push rod operation. The setting of the screw sleeve plays a limiting role for the nut, avoiding the nut from slipping off the lead screw.

[0005] However, in some work scenarios such as drawing, design, programming, etc., the user may need to frequently rotate the table board to adjust the working angle or view the screen content, so that the user may need to frequently leave the seat to adjust the working angle or view the screen content, thereby reducing the work efficiency and possibly increasing the physical fatigue and discomfort.

[0036] The support mechanism 3 comprises a cylinder body 34 fixedly arranged at the upper end of the table leg 1 at the middle position, and a lifting assembly 31 fixedly arranged inside the cylinder body 34, the lifting assembly 31 being a push rod motor commonly used in the prior art and suitable for the embodiment, so as to facilitate the lifting of the lifting table, the push rod motor having a top rod 310;

[0037] Meanwhile, a table plate 2 is installed at the top end of the top rod 310, so as to realize the purpose of lifting of the top rod 310 under the driving of the push rod motor;

[0038] As shown in Figures 1-2 and Figure 4 in order to adjust the table plate 2 to a comfortable angle while lifting, an adjusting assembly 33 is installed between the top rod 310 and the table plate 2, the adjusting assembly 33 being used for adjusting the table plate 2 to a suitable angle as required;

[0039] The adjusting assembly 33 comprises a mounting shell 330 fixedly arranged at the upper end of the top rod 310, a screw rod 331 rotatably arranged inside the mounting shell 330, and a second motor 332 fixedly arranged at one end of the mounting shell 330, the output end of the second motor 332 being fixedly connected with one end of the screw rod 331, so that the second motor 332 can drive the screw rod 331 to rotate on the mounting shell 330;

[0040] Meanwhile, a screw block 333 is slidingly arranged inside the mounting shell 330, the screw block 333 being in transmission connection with the screw rod 331, so that the screw block 333 can slide along the inside of the mounting shell 330 under the driving of the second motor 332;

[0041] The screw block 333 is hingedly connected with a connecting rod 334, and an inclined rod 335 is hingedly connected at one end of the mounting shell 330, and the connecting rod 334 is hingedly connected with the middle position of the inclined rod 335, so that when the screw block 333 slides along the inside of the mounting shell 330 under the driving of the second motor 332, the inclined rod 335 can be lifted through the connecting rod 334;

[0042] Meanwhile, one end of the inclined rod 335 is hingedly connected with the mounting shell 330, so that when the connecting rod 334 lifts the inclined rod 335, the inclined rod 335 will rotate and incline around one end of the mounting shell 330 until it stops at a suitable position;

[0043] And the tilt rod 335 is fixedly provided with a plurality of support rods 337 for fixedly connecting the table plate 2, so that the table plate 2 can be stably operated;

[0044] When the table plate 2 needs to be adjusted, first, the second motor 332 is started to drive the screw block 333 to slide along the inside of the mounting shell 330, and at the same time, the connecting rod 334 on the screw block 333 lifts the tilt rod 335, so that the tilt rod 335 starts to rotate and tilt around one end of the mounting shell 330, at this time, the table plate 2 starts to tilt with the tilt rod 335, until it tilts to the appropriate position and stops, thereby achieving the purpose of adjusting the angle of the table plate 2.

[0045] If the angle of the table plate 2 needs to be restored, the second motor 332 is only needed to drive the screw block 333 to slide along the inside of the mounting shell 330 to the initial position, so that the original angle of the table plate 2 can be restored.

[0046] As shown in Figures 1-3 In order to enable the user to rotate the table plate 2 while using the lifting table to perform lifting operation, so that the user can complete the work content without leaving the seat in some working scenarios, and can more conveniently take the objects at the end far away from oneself, thereby improving the work efficiency, a turning assembly 32 is rotatably arranged on the cylinder 34, and the turning assembly 32 is used to rotate the table plate 2 according to the needs of the user to achieve the effect of convenient work.
