The present invention relates to a height adjusting device on a bookshelf, and more particularly, on a bookshelf on which a height is adjusted by separating the lower pipe and the upper pipe, the legs on the bookshelf are provided with a lower pipe having a height adjusting groove at a predetermined interval, and The upper pipe is inserted into the lower pipe and slides up and down to adjust the fit of the height adjustment groove of the lower pipe, the upper pipe is installed, and the closing cap fitted to the upper end of the lower pipe to fill the gap between the upper pipe and the lower pipe It is made, the height adjustment unit is inserted into the inside of the upper pipe, the control pin is coupled to the main body while being fitted to the outer surface of the rectangular groove formed on the upper side of the upper pipe, the lifting and lowering the main body, and Is formed in the lower part of the main body but inclined at a predetermined angle from the top to the bottom A sliding part having a rail formed therein, a fixing pin inserted into the sliding part and having an inclined surface corresponding to the rail so as to be in close contact with the rail, and being inserted into the sliding part, and the fixing pin is inserted into the height adjusting groove. A spring providing elasticity to the fixing pin to be inserted and coupled to surround the sliding part, and an opening is formed on one side so that the fixing pin protrudes outward, and a groove is formed on the other side of which the spring is seated. It relates to a height-adjusting device on a bookshelf, characterized in that it comprises a cover.

In general, desks and stools used by students in schools or academies are standardized based on students' standard physical indices and have been used for a long time until they are not available.

However, the standard size of the bookshelf has a problem of making a bent posture due to the difficulty of maintaining the correct posture of the growth period of the youth of the height is not fit because the degree of physical development is different.

Complement this to the structure that can adjust the height by stretching the legs in the structure of the existing bookshelf, the upper pipe is coupled to the top plate or the seat plate for adjusting the height and the lower pipe supporting it, and fixed by the height adjustment opening Structure was used. However, the above structure is inevitably caused in the fixed coupling state due to the clearance applied to the upper and lower pipes to facilitate height adjustment during assembly or use.

Due to such a problem, a shake prevention structure having a structure that prevents shaking by eliminating the clearance between the height adjusting opening and the upper and lower pipes is used.

Conventional desk height adjustment device and the anti-shake structure is a structure in which the upper structure of the desk is integrally formed with the upper plate, including the upper plate, and the lower structure, which is integrally coupled with the lower support, including the lower support, is coupled to the legs, the The leg is separated into an upper pipe constituting the upper structure and a lower pipe constituting the lower structure, and fixed by the height adjusting means with the lower pipe inserted in the upper pipe, by the anti-shake means at the lower end of the upper pipe. It is made of a fixed contact structure.

The height adjusting means is composed of a fixed bushing coupled to the pin hole formed in the upper pipe and the main body fixed to the upper end of the lower pipe, the cap is screwed to the main body to secure the fixed bushing, the anti-shake means at the bottom of the upper pipe It is made of an insertion ring to be inserted, and a push rod that fixes the insertion ring to the lower pipe. The anti-shake structure was able to solve the problem of shake at the source by providing a very stable state on the stand of the two legs structure easy to shake.

However, the above-described structure is complicated to adjust the height of the height of the bookshelf by loosening the cap tightly and exposing the fixing bushing while adjusting the pinhole engagement position of the fixing bushing to the height and fixing the cap again. And difficult to operate.

In addition, the structure is easy to damage or loss of the fixed bushing, the height adjustment means is a key element, in that case there is a disadvantage that the function of the bookcase is lost, the main body, the cap and the fixed bushing constituting the height adjustment means are assembled respectively Since these components are configured separately from the anti-shake means, the manufacturing and assembly processes are also complicated.

The present invention can be easily and simply adjust the height of the younger students, do not arbitrarily separated in the internal components are assembled to prevent the loss of function due to the loss or damage of parts, the anti-shake means can also perform the height adjustment function It is invented for the purpose of making it easy to manufacture and maintain.

In addition, it is invented so that the user can perform the height adjustment in a comfortable posture so that the portion for adjusting the height is located at a height that is easy to operate.

In order to solve the above problems, the present invention is divided into a lower pipe and an upper pipe, the height of which is adjusted on a bookshelf, wherein the leg portion of the bookshelf is inserted into the lower pipe and the lower pipe in which a predetermined height adjustment groove is formed; Sliding up and down is made up of the upper pipe is installed with a height adjustment portion is adjusted to fit the height adjustment groove of the lower pipe, and the closing cap fitted to the upper end of the lower pipe to fill the gap between the upper pipe and the lower pipe, the height The control unit is inserted into the main body inserted into the upper pipe, the control pin is coupled to the main body while being fitted to the outer surface of the rectangular groove formed on the upper side of the upper pipe, and is formed on the lower portion of the main body, Rail is formed to be inclined at a predetermined angle from the top to the bottom A sliding part, a fixing pin inserted into the sliding part and formed with an inclined surface corresponding to the rail so as to be in close contact with the rail, and fixed to be inserted into the sliding part and inserted into the height adjusting groove. A spring providing elasticity to the pin and coupled to surround the sliding portion, and one side is formed with an open hole so that the fixing pin protrudes to the outside, and the other side includes a cover formed with a groove in which the spring is seated Characterized in that made.

In addition, the main body is characterized in that the grid-shaped reinforcement is formed to reduce the weight while preventing shaking and ensuring strength.

In addition, the cover is characterized in that the hook is formed to facilitate the coupling with the upper pipe.

The present invention can be easily and simply adjust the height of the younger students, the internal components are not separated arbitrarily in the assembled state to prevent the loss of function due to the loss or damage of parts, the anti-shake means can also perform the height adjustment function. It is invented for the purpose of facilitating manufacture and maintenance by configuring it.

In addition, it is possible to perform the height adjustment in a comfortable posture by installing the height adjustment pin at a height that is easy for the user to operate.
