SOLUTION: In a block provided on a bottom surface of a fixed top plate, a metal screw rod having one end fixed is provided with a corresponding perforation formed in a block provided on a bottom surface of a pivotable top plate. A pair of top plates is formed by screwing a swivel bar having a screw hole at the other end of the extended screw rod. Also, the pivotable top plate can adjust its assembly angle as desired by loosening or tightening the pivot bar at the user's request. A desk frame upright with an ant mortise is fixed to the bottom surface of the fixed top plate, so that the desk frame upright is provided with an ant mortise receiving seat corresponding to the ant mortise. It can be inserted in. An elongated slot is formed on the outer surface of the upright cover opposite to the ant mortise receiving seat, and a turning button having a screw rod is inserted into the slot and screwed into the screw hole of the dove mortise. The height of the top plate can be adjusted arbitrarily by loosening or tightening the button.

 In view of the above problems, the applicant has actively conducted research and development based on his or her multi-year practical experience in the field, and adjusted the assembly angle and height of the top plate according to the user's actual use requirements. Provide a desk structure that can be adjusted and used by users to read and write documents, write pictures, place music scores, etc., and greatly improve the convenience and practicality of desks The purpose is to:

[0005] In order to clarify specific technical means and configurations of the present invention, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0006]

1 to 3 show an embodiment of the present invention. The desk includes a fixed top plate 10, a pivotable top plate 20, a desk frame upright 30, a upright cover 40, and a width direction support leg frame 50 as described later. Components. A block 11 is provided at the center of the bottom surface of the fixed top plate 10, and an insertion slot 12 is formed on a side of the block 11 close to a pivotable top plate 20 described later. A metal plate 14 is fixed to the side of the block 11 by a plurality of screws 13, and one end of a long metal rod 15 extending through the metal plate 14 to a pivotable top plate 20 is formed as a block. 11 is fixed inside. A block 21 is provided at the center of the bottom surface of the pivotable top plate 20, and a perforation 22 is formed in the block 21 along the longitudinal direction thereof. In order to assemble the top plates 10 and 20 to complete a set of top plates, first insert the long screw rod 15 into the perforation 22 and penetrate it, and then attach two washers to the other end of the long screw rod 15. It is necessary to thread a turning bar 25 having a screw hole 24 formed therein through the other end thereof into the other end of the long screw rod 15. Two flanges 31 are provided on the upper part of the desk frame upright 30. Two right angle support plates 32 and a plurality of right angle support plates 32 are mounted on an assembly assembled by mounting these flanges 31 in the insertion slots 12 of the block 11. By attaching the screws 33, the desk frame uprights 30 are positioned and fixed to the fixed top plate 10. A dove mortise 34 is formed on one side surface of the desk frame upright 30 along the longitudinal direction thereof, and a screw hole 35 for fixing the desk frame upright 30 is formed at an appropriate position of the dovetail mortise 34. Have been. An ant mortise receiving seat 41 corresponding to the ant mortise 34 of the desk frame stanchion 30 is provided in a hole formed inside the upright cover 40. By engaging, the desk frame upright 30 can be inserted into the hole. An elongate slot 42 is formed on the outer surface of the upright column cover 40 opposite to the receiving seat 41, and a swivel button 44 having a screw rod 43 is provided with two washer 45 through the dovetail mortise 34. The support leg frame 47 having the casters 46 at the lower end of the upright column cover 40 can be mounted thereon. A caster 51 is provided on the bottom surface of one end of the width direction support leg frame 50, and the other end is formed of two screws 52 and a double hole nut 53 to which these screws 52 are screwed. By the action, it is inserted and fixed to the insertion slot 48 formed at the lower end of one side surface of the upright column cover 40.

Further, as shown in FIGS. 4 and 5, when it is desired to adjust the assembling angle of the pivotable top plate 20 or the height of the entire desk after assembling the above members, simply rotate the corresponding pivot. The purpose can be achieved by loosening the turning bar 25 and the turning button 44. After the adjustment is completed, the swivel bar 25 or the swivel button 44 may be re-tightened, which has a favorable convenience.

As described above, there is no commercial product identical to the present invention before the filing of the present invention, and since it is not described in the related literature, it has “novelty” and “inventive step”, It has the right to be protected by the utility model law, because it meets the basic requirements of the model, and submits the application here in accordance with the utility model law.
