Description

Table with lifting function

technical field

The utility model relates to a table, in particular to a table with a lifting function that a user can use a control device to simultaneously drive two lifting devices and a linkage device to adjust the distance between the table platform and the ground by facing the front end of the table.

Background technique

The early tables were generally designed with a fixed height, and they could not be adjusted according to the user's needs or height, which was quite inconvenient to use.

Therefore, there is a lifting table that can be adjusted by the user, such as: a lifting table, the lifting table is provided with a table leg, a support frame is arranged on the table leg, and two adjustment connecting rods are pivotally arranged on the support frame upper end. , the lower ends of the two adjusting links are oppositely provided with protruding teeth that can be engaged with each other, and the top of the two adjusting links is connected with a bracket fixed on the fixed rod under the desktop. Both ends of the shaft are respectively provided with opposite external threads, and the screws at both ends of the support shaft are provided with an adjustment seat, which is pivotally connected with the adjustment connecting rod through a pivot shaft. The shaft is extended, and one end of the bracket is provided with a rocker to be connected with the support shaft.

When it is necessary to adjust the height of the desktop, use the rotating handle to drive the fulcrum in the bracket to rotate, and the corresponding adjustment seat on the fulcrum can be moved left or right under the drive of the screw thread, and then the two adjustment links are connected. The rods are relatively closed or opened to achieve the function of adjusting the height of the desktop.

However, the joystick is located at one end of the bracket and protrudes from the side of the desktop, causing the side of the lift desk joystick protruding from the desktop to be unable to lean against the wall, resulting in waste of space and limitations in space layout, and people walking beside the lift table Sometimes, more clothes are hooked by the crank handle, causing safety doubts.

Therefore, in view of the shortcomings of the above prior art, someone has proposed an improvement method. For example, as the Chinese patent application No. 200820117373.7 "lifting table" patent, the improvement lies in that the connecting rod is arranged between the two movable frames of the tripod unit. The two ends of the connecting rod pass through the positioning holes on the upper frame bodies of the two movable frames respectively, and then connect with the corresponding engagement grooves of the helical gears, so that the multiple helical gears located on both sides of the connecting rod can have a linkage relationship , the crank handle has a shaft connection portion whose shape corresponds to each engaging groove.

When it is necessary to adjust the height, insert the shaft connection part of the handle into the through hole of the table, and then insert it into the engaging groove of the helical gear with the opening facing upwards, and rotate the handle to pass through the shaft connection part of the handle The connected helical gear rotates, and then the other helical gears meshed with the helical gear rotate, synchronously interlocking the telescopic displacement of each screw rod relative to each sleeve, and at the same time through the transmission of the connecting rod. The synchronous linkage effect makes the table board move up and down under the telescopic drive of the screw rod. And when the table top has reached the appropriate height, the user can take the crank handle away.

However, the user has to remove the handle for the convenience of using the desktop. This action still causes considerable inconvenience to the user. If the handle is accidentally lost, it is equivalent to the complete loss of function of the lift table. Therefore, the lift table Reliability is still quite low.

In view of the fact that the above-mentioned problems in the prior art cannot be effectively solved and overcome, the applicant proposes this patent application to solve the above-mentioned problems.
