The present invention relates to a desk having a height adjusting member, and more particularly to a desk having a height adjusting member for maximizing convenience as well as use efficiency by allowing the user to easily adjust the height of the desk.

In general, the desk is a kind of parish used in educational facilities such as schools or academies, and is manufactured and used according to specifications according to the average body shape of students.

However, in recent years, the growth rate of students is increasing day by day due to the westernized diet, but the school or academy uses desks with uniform height regardless of the student's body shape (sitting posture). There is a problem that the physical strain of the student will occur.

However, replacing the existing desk with a new desk that is suitable for the student's body shape adds to the economic burden, which has made practically impossible limitations.

Therefore, in the related art, in order to solve the problems caused in using the desk as described above,

A lower inclined sphere having a rotary shaft screwed to a fixed socket of the lower support and an outer inclined surface on the rotary shaft, a cylindrical positioning tool half divided by a longitudinal incision groove, an upper inclined sphere, an upper inclined sphere fitted to the recessed side of the positioning tool, and an outer peripheral surface Utility model registration No. 0264036 "chair or desk of which is provided with an incision groove and a screw cap insertion recess at the upper end, and the upper fixing member consisting of a screw on the outer peripheral surface is sequentially fastened, and a cap fixed to be rotated at the top of the rotating shaft. "Height adjustment device" has been barred.

However, in the conventional "chair or desk height adjusting device" when the user holds the lower column to rotate (forward or reverse) to adjust the height, the upper fixing member spirally coupled to the rotating shaft is lowered or In this case, the upper fixing member has a disadvantage of not having a structure that can be firmly adhered to support the weight of the upper housing only by lowering or raising only the inner diameter of the upper housing.

In particular, the conventional "chair or desk height adjustment device" is the upper fixing member is lowered by the rotation of the rotary shaft, the upper inclined portion is rotated together with the rotary shaft, so that only the rotation in place without rising or falling While the lowering is in contact with the upper fixing member, as a result, the upper fixing member and the upper inclined portion is in close contact with each other can no longer rotate the rotary shaft.

In addition, the conventional "height or desk height adjusting device" is provided with two upper inclined portion and the lower inclined portion that can be raised or lowered by the rotation of the rotary shaft, which is substantially to rise or descend by the rotation of the rotary shaft I have a lot of trouble.

That is, the upper inclined portion and the lower inclined portion has a mechanical structure that can not only rise or descend by itself but only rotate together with the rotating shaft.

In addition, the conventional "chair or desk height adjusting device" is assuming that it can be raised or lowered by the rotation of the rotating shaft (see the operation principle of the upper inclined portion and the lower inclined portion looking at the same time in accordance with the rotation direction of the rotating shaft) Because it has a structure that must rise or fall uniformly,

As a result, when the rotary shaft is rotated forward to fix the height adjusting device, the upper inclined portion descends and contacts the position adjusting tool so as to be pressed against the inner diameter of the upper housing to maintain the fixed state. In order to rotate the rotating shaft in reverse, the upper inclined portion rises, but at the same time, the lower inclined portion rises again to squeeze the position adjusting tool, which causes a serious problem that the height adjusting device cannot be separated.

That is, since the upper inclined portion and the lower inclined portion have a structure that can only be raised or lowered at the same time, the positioning device cannot be efficiently compressed and separated from the inner diameter of the upper housing.

Moreover, the conventional "chair or desk height adjusting device" has a limitation that the use efficiency and range of use can be extremely limited due to the inconvenience and hassle of use because the structure is complicated and solid support cannot be secured.

Therefore, the structure is simple and easy to operate so that students can easily adjust the height of the desk height adjustment means of the desk to increase the use efficiency and range of use is more urgently needed than ever.

As such, the present invention has been devised to solve the conventional problems as described above.

An object of the present invention is to provide a desk with a height adjustment member that allows the user to easily operate, as well as secure a solid support force to efficiently adjust the height of the desk.

Another object of the present invention is to provide a desk provided with a height adjusting member that can be applied to the support legs of the existing desk to increase the use efficiency and utilization range.

Still another object of the present invention is to provide a desk having a height adjusting member that can form a height display scale so that a user can visually check the height of the desk to improve convenience in use.

When described in more detail by the accompanying drawings the technical configuration for achieving the object of the present invention as described above are as follows.

Figure 2 is an exploded perspective view for showing the structure of the height adjustment member in the present invention, Figure 3 is a combined perspective view for showing the structure of the height adjustment member in the present invention, Figure 4 is a cross-sectional view of the AA line of FIG. will be.
