Device for adjusting height of panel

Technical Field

The invention relates to a table, a chair and a workbench, in particular to a device capable of adjusting the height of a panel.

Background

At present, most of common desk, chair and workbench of people are fixed in height, so that the desk, chair and workbench are not suitable for people with different heights; a fixed height of table and chair and work bench is difficult to achieve for a person who wishes to alternately sit and stand for learning and work. Although various types of adjustable height tables and chairs are manufactured, most lifting parts have a heavy weight. Some of the structure is a thick rod sleeved thin rod structure and slides relatively, and other structure is provided with a telescopic structure and a folding structure, but the stability is not strong, the rocking is easy, and the operation is inconvenient; there are also tables and chairs with automatically adjustable height, but the structure is more complicated. Most of the devices are not modified on the original table and chair and the original workbench, and resources are wasted.

Disclosure of Invention

In order to solve the defects of the existing table and chair and workbench with adjustable height, the lifting part designed by the invention only consists of a support frame with light weight and simple structure and a new panel, and the designed support frame is directly placed on the original panel.

The technical scheme adopted by the invention for solving the technical problem is as follows:

a device for adjusting the height of a panel comprises a new panel, a support frame and an original panel after transformation. The support frame comprises a plurality of bearing horizontal poles, a plurality of vertical support structures, a plurality of horizontal shelving structures, and the bearing horizontal pole is connected with vertical support structure's top, and all vertical support structures are parallel to each other, are connected with a plurality of horizontal shelving structures in every vertical support structure's not co-altitude department, and horizontal shelving structure can shelve on the panel of original panel after reforming transform shelves the position. The new panel is secured to the load-bearing rail. The original panel after transformation is provided with the small hole holes the same as the number of the vertical supporting structures, one end of each small hole is wide, the other end of each small hole is narrow, the vertical supporting structures and the transverse shelving structures can simultaneously penetrate the wide positions of the small holes, the narrow positions of the small holes only allow the vertical supporting structures to pass through, and the transverse shelving structures do not pass through. And arranging a blocking strip on the upper surface of the modified original panel at one side of the edge of the small hole close to the transverse shelving structure, wherein the blocking strip is arranged between the shelving part of the panel and the opening of the small hole, is close to the small hole but not right above the small hole, and is arranged for preventing the transverse shelving structure shelved on the modified original panel from freely sliding horizontally. After each vertical supporting structure passes through the small hole, the bottom end of each vertical supporting structure is made into a 90-degree hook so as to prevent the vertical supporting structure from being freely and completely drawn out from the small hole.

The fixing mode of the new panel and the bearing cross bar is as follows: the bearing cross rod can be clamped by the clamping grooves of a plurality of fixing clamps, the fixing clamps are nailed to a new panel after the nails penetrate through the clamp eyelet holes of the fixing clamps, the clamping grooves are arranged in the middle of the fixing clamps, and the clamp eyelet holes are arranged at two ends of the fixing clamps. The bearing cross bar can be provided with a plurality of cross bar thin holes, and the bearing cross bar is nailed to a new panel after the nail penetrates through the cross bar thin holes. The nail can also be changed into a bolt and a nut, and the part of the new panel corresponding to the bolt is dug out of an eyelet.

And arranging a connecting reinforcing plate on the lower surface of the modified original panel at one side of the edge of the small hole close to the transverse laying structure, wherein the connecting reinforcing plate is close to the small hole but not under the small hole.
