Description

A desk with lift function

technical field

The utility model relates to the technical field of office furniture, in particular to a desk with a lifting function.

Background technique

A desk is an essential office equipment in an office. At present, the existing desks on the market are mainly in a fixed form or an assembled form, and their height adjustability is poor, or the operability is relatively complicated. In the process of using, generally the staff who mainly sit in the sitting position, due to the different heights of the staff, when the height of the desk is not suitable, the taller staff often needs to bend over and work at the desk; Low-level workers often need to raise their arms to place on the tabletop and maintain muscle tension.

The existing Chinese patent document with the publication number of CN202908121U provides a desk with a lifting device, including an upper table top, a lower support column, and a table between the upper support column and the lower support column for adjusting the height of the upper table top. Lifting device; the lifting device includes a lifting cylinder, an air pump, a one-way valve and an air release valve, the cylinder barrel of the lifting cylinder is fixed on the bottom of the upper tabletop, the piston rod of the lifting cylinder is fixed on the lower support column, the The air pump is communicated with the cylinder through the air pipe, the one-way valve and the air release valve are installed on the air pipe, and the air release valve is located between the cylinder and the one-way valve. The above setting enables the height of the desk to be adjusted, and can meet the needs of height adjustment.

The shortcomings of the above technical solutions are: when the table top is to be raised, the table top is pressed, the air release valve is closed, and the air pump is pumped upward through the one-way valve to the cylinder barrel. Because the piston rod is fixed on the lower support column, the piston rod remains stationary. , at this time, the cylinder will drive the upper table to rise gradually. When the upper table rises to the required height, turn off the air pump; when the upper table needs to be lowered, open the air valve to make the upper table drop to the required height, and then close the air release valve. . Since there are often two or more legs on a desk, it is necessary to operate the air cylinders of each leg separately when the air cylinder is used to deflate the air. Since the amount of deflated air is often difficult to achieve the same amount, it is not easy for the desk to move up and down. Keep it level. For this problem, a new solution is required.

Utility model content

The purpose of the utility model is to provide a desk with a lifting function, which can realize the level of the desktop during the lifting process.

The purpose of this utility model is achieved through the following technical solutions:

A desk with a lifting function, comprising several legs and a desktop, the legs are fixed on the bottom surface of the desktop, the legs include a fixed leg and a lifting leg; one end of the lifting leg is in contact with the bottom surface of the desktop. Fixed, the other end of the lifting leg is nested with the fixed leg, and the fixed leg is provided with a lifting device that drives the desktop to rise and fall; the lifting device includes a driving part, a screw rod and a threaded sleeve. The installation of the driving part Inside the fixed leg, one end of the screw rod is fixed with the driving member, and the other end of the screw rod is connected with a threaded sleeve, the threaded sleeve is located inside the lifting leg, and the driving member inside each fixed leg is synchronized by the controller Control the lift.

By adopting the above technical solution, the table legs play the role of supporting the desktop. Since the table legs are provided with lifting devices, the lifting legs of the table legs can be extended or shortened; There is a thread, so when the lead screw rotates, the lifting leg with a threaded sleeve on the other end of the lead screw goes up and down, so the lifting leg can drive the desktop to go up and down; Therefore, the function of lifting and lowering the lifting legs connected to the same desktop in a unified manner can be realized.

The utility model is further configured as follows: a stable support member is fixed at the fixed end of the lifting leg and the table top, the stable support member is fixed with the bottom surface of the table top, and the length direction of the stable support member is parallel to the width direction of the table top.

By adopting the above technical solution, the stable support is fixed with the upper end of the lifting leg, so the stable support can support both ends of the desktop during the lifting process of the lifting leg. Since the stable support is fixed with the lifting leg, Since the lifting legs are fixed with the stable support, the contact area between the table legs and the table top can be increased, and the table top has a stable support to support the table top when the force is unbalanced, so that the table top is not easy to roll over during the lifting process.

The utility model is further set as follows: the height adjustment range of the desktop is 750mm~1350mm.

By adopting the above technical solution, when the height of the desktop is 750mm, it can adapt to the height of the staff in normal sitting posture. When the staff is high, the height of the lift can continue to be adjusted upward, and when the height of the desktop is 1350mm, the work Personnel can use the desk while standing to reduce discomfort from prolonged sitting.

The utility model is further configured as follows: the bottom surface of the table top is fixed with two table legs, and the table legs are arranged at both ends in the length direction of the table top.

The beams and the beams, the connecting beams and the fixed legs are all connected inside, and the vertical partitions are fixed to the beams and/or the connecting beams by being fixed.

By adopting the above technical solution, a connecting beam is connected between the two fixed legs, and the connecting beam can make the table legs more stable, so that the table legs are not easy to shake during lifting or use; the cross beam further strengthens the connection between the connecting beams. The distance between the connecting beams is fixed, so the connection firmness between the structural leg tables can be increased; the vertical partitions are fixed with the beams or the connecting beams, so the vertical partitions are not easy to move with the lifting of the table top.

To sum up, the beneficial technical effects of the present utility model are:

1. A driving member is set inside the table leg to control the rotation of the screw rod, which drives the table top to rise and fall, and the driving member controls the rotation of the driving member at the same time. Therefore, the rotation of the driving member is synchronized, and the table top can be kept in a horizontal state during the lifting and lowering process;

2. The bottom end of the fixed leg is provided with a height-adjusting foot pad. When the rotating screw hole rotates, the fine-tuning screw can be kept away from the base, so that the height-adjusting foot pad can be raised, which can play a role of fine-tuning. When the desktop becomes inclined , can fine-tune the height of the foot pad to keep the desktop level;

3. There are two desktops, so a whole desk can be used for two staff to work, and there are vertical partitions between the two desktops. In addition to the vertical partitions, they can be used for separation, and there are evenly distributed magnetic drawing boards inside. It can also be matched with magnets to fix thin paper on the vertical partition, and play the role of memo, reminder and so on.
