Abstract

The invention discloses a writing desk. The writing desk comprises a desk top, wherein four corners at the bottom of the desk top are respectively provided with a pivot joint seat, each pivot joint seat is connected with a first end of a toothed strip in a pivoting mode, a second end of each toothed strip is inserted into a hollow pillar, a cross rod is inserted in the middle of each hollow pillar, one side of each cross rod abuts against a toothed port of each toothed strip, the other side of each cross rod abuts against a first end of a reset spring, a second end of each reset spring abuts against the inner wall of each hollow pillar, and a plurality of through grooves, corresponding to the moving direction of each cross rod, are formed in the lateral portions of each hollow pillar. According to the writing desk, the table top can ascend and descend by utilizing the relative motion of downwards inclined toothed strips and the cross rods, and the desk top and the toothed strips are mutually connected in a pivoting mode so that the inclination of the desk top can be freely adjusted.

Example Embodiment

[0009] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0010] Refer to figure 1 As shown, the writing desk 1 of the present invention includes a table top 10. The bottom four corners of the table top 10 are respectively provided with a pivot seat 11, and the pivot seat 11 is pivoted with a tooth-shaped downward rack 12 to cooperate with figure 2 As shown, the first end 121 of the rack 12 is pivotally connected to the pivot seat 11, and the second end 122 of the rack 12 is inserted into a hollow column 13, and a cross bar 14 is inserted in the middle of the hollow column 13. A cross bar 14 is set on both sides of the writing desk 1, and the two ends of the cross bar 14 respectively pass through the corresponding two hollow columns 13, for further reference image 3 As shown, one side of the cross bar 14 abuts the toothed lower surface 123 of the rack 12, the other side of the cross bar 14 abuts the first end of a return spring 15, and the second end of the return spring 15 abuts the hollow The inner wall of the column 13 is used to push the cross bar 14 back and against the rack 12 after the rack 12 moves up to the position. A through slot 16 is respectively opened on both sides of the hollow column 13 corresponding to the moving direction of the cross bar 14.

[0011] When using the writing desk 1 of the present invention in particular, drag the desktop 10 upwards, the rack 12 moves upwards, first push the cross bar 14 outwards, and press the return spring 15 to contract inward. When the rack 12 rises to complete a tooth, The return spring 15 pushes the cross bar 14 to move in the direction of the rack 12 to resist the rack 12 again, thereby locking the rack 12; when adjusting the table top 10 downwards, pull the cross bar 14 away from the rack 12, in turn The rack 12 is lowered, and after the adjustment is in place, the cross bar 14 is released, and the cross bar 14 is pressed against the rack 12 again under the action of the return spring 15 to lock the rack 12. The rack 12 is pivotally connected to the desktop 10, so the inclination of the desktop 10 can be changed by adjusting the positions of different racks 12, which can be used as a drawing board or the like.

[0012] The present invention has been described in detail above in conjunction with the embodiments of the drawings, and those of ordinary skill in the art can make various changes to the present invention based on the above description. Therefore, some details in the embodiments should not constitute a limitation to the present invention, and the present invention will take the scope defined by the appended claims as the protection scope of the present invention.
