Description

A liftable writing desk

technical field

The utility model relates to a reading tool, which is mostly used for school study, more specifically, it relates to a writing desk which can be lifted and lowered.

Background technique

The desks and chairs used by students in class are a kind of desks and chairs, also called student desks and chairs. Existing desks and chairs can not only adjust the height, but also have a kind of connected desks and chairs, which are composed of height-adjustable desks, chairs and connecting plates with adjustable intervals. The table height, chair height, and distance between tables and chairs cannot be adjusted. It is suitable for students of all ages and shapes. It can be adjusted according to the individual situation of each student to fully meet the hygienic standards of desks and chairs.

The height adjustment of the writing desk in the prior art is to set the legs of the table into two connecting rods separately, and the two connecting rods are nested with each other, and then by presetting equidistant mounting holes on one of the connecting rods, through One bolt fixes the two connecting rods. When the height needs to be adjusted, the bolt is pulled out, then adjusted to a predetermined position, and then the bolt is inserted to complete the fixing.

However, there are certain problems in the use process. Since the height is adjusted through the bolt, the load-bearing position will be transferred to the bolt, so the bolt is very easy to loosen and the mounting hole is easy to wear.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a liftable writing desk which prevents the pins from being worn or loosened by locking the sliding rod and the support frame.

In order to achieve the above object, the utility model provides the following technical solutions: a liftable writing desk, including a storage drawer and stool legs for supporting the storage drawer, the stool legs include a sliding rod and a support frame, the sliding The rod is sleeved on the support frame, the support frame is provided with a number of positioning holes, the sliding rod is provided with a mounting hole, and the mounting hole and the positioning hole realize the connection between the support frame and the sliding rod by passing through the bolt. fixed, the sliding rod is also covered with a rubber sleeve, the rubber sleeve is slidingly connected with the sliding rod, and the rubber sleeve includes an inner sleeve and an outer sleeve integrally arranged, when the rubber sleeve slides to the When the top surface of the support frame is pressed, the inner wall of the support frame squeezes the inner sleeve and locks the sliding rod.

Under normal circumstances, its general use method is the same as that of an ordinary liftable writing desk: if you need to adjust its height, first remove the latch, then determine the relative position of the support frame and the sliding rod, and then install the hole and the positioning hole When it is facing and the height is similar to the required height, then insert and fix the bolt. In this case, the bolt plays a more load-bearing role. Function, locking the sliding rod to achieve fixation, so that the force can be shared, and the latch will not be easily worn.

Further: the surface of the inner sleeve is provided with several locking protrusions. The frictional force can be further increased through the arrangement of the locking protrusions, and at the same time, when the locking protrusions are squeezed, deformation is bound to occur, so as to ensure the stability of the structure.

Further: the locking protrusion is set in an arc shape. By setting the locking protrusion in an arc shape, it is ensured that it is not easy to wear, and both the frictional force and the deformation effect can be reflected.

Further: support beams are also connected between the support frames, the support beams include support beams respectively fixed to the support frames, the support beams include extension parts and connecting parts, and the extension parts are away from the opening direction of the storage drawer Extend and transition through the junction. Compared with ordinary support beams, the arrangement of the extension part of the support beam achieves a better fixing effect under the premise of ensuring firmness.

Further: the top surface of the rubber sleeve is provided with a pressing part, and the pressing part is provided with anti-skid lines. Through the setting of the pressing part, a large stress-bearing area is provided for the user, and it is convenient for the user to squeeze the inner sleeve between the support frame and the sliding rod.

Further: anti-slip lines are provided on the surface of the jacket away from the sliding rod. Through the setting of the coat, the force-bearing area when it is taken off is guaranteed.

By adopting the above-mentioned technical solution, under normal circumstances, its general use method is the same as that of an ordinary liftable writing desk: if it is necessary to adjust its height, first remove the latch, and then determine the relative position of the support frame and the sliding rod. Then when the mounting hole is facing the positioning hole and the height is similar to the required height, insert and fix the latch. The role of the rubber inner sleeve and the outer sleeve is to lock the sliding rod to achieve fixation, so that it can share the force and prevent the pin from wearing easily.
