Description

Technical Field

[0001] The invention relates to a writing table, in particular to a foldable writing table with an adjustable tabletop inclination angle. Background Art

[0002] Writing desks are mostly used for hand-drawing and writing, and are particularly widely used in classrooms, studios, and offices. When the writing desk needs to be moved to the placement area, the writing desk has a certain volume, which makes it cumbersome to carry. Moreover, when the venue needs to vacate space for activities, the larger desk is also likely to occupy a certain amount of the vacated activity space.

[0003] Publication number CN108402656A is a Chinese invention patent, which discloses a foldable desk. Its technical solution includes a desktop and a fixed seat. The desktop is connected to a table leg that can adjust the height of the desktop by changing its own shape. There are two table legs, which are installed on the left and right sides of the desktop respectively. The upper end of the table leg is hinged to the desktop, and the lower end is hinged to the fixed seat. Each hinge is provided with a fixing buckle that can limit their relative rotation; the side wall of the desktop is provided with a foldable bookshelf. The table legs of this device can change the height to adapt to students who are in the growth stage and are growing in height. When not in use, the table legs can be retracted to the lowest level, and the desktop can be lowered to the lowest level to put the desk in a folded state to reduce the occupied space.

[0004] In combination with the above structure, the writing table can be stored in a folding manner.

[0028] The implementation modes of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0029] like Figures 1 to 12As shown, a foldable writing table with adjustable desktop inclination angle comprises: a desktop panel 1, a cabinet 2, a toggle plate 3, a first swing foot 4, a second swing foot 5, a drawer 6, a storage box 7 and a side panel 21. The desktop panel 1 and the cabinet 2 are stacked up and down, and two side panels 21 are provided. The two side panels 21 are respectively arranged on two opposite sides of the cabinet 2. Each side panel 21 is away from the cabinet 2 and has a shaft column at both opposite ends. The two shaft columns of each side panel 21 are respectively fixed to the first swing foot 4 and the second swing foot 5; The upper surface of the desktop panel 1 is provided with a notch on both sides of the two side panels 21, each notch of the desktop panel 1 extends between the cabinet body 2 and each side panel 21, and a fixing plate 31 is provided in each notch of the desktop panel 1 and fixed to one end of the fixing plate 31, and the other end of each fixing plate 31 extends between the cabinet body 2 and one side panel 21, and the opposite sides of the two fixing plates 31 are respectively closely fixed to the vertical side of the notch of the desktop panel 1, and the two fixing plates 31 are respectively provided with a dial on the side facing outwards. The movable plate 3 is arranged at an angle, and the upper end of each movable plate 3 is close to the upper end of the fixed plate 31, and the lower end of each movable plate 3 is inclined to the side away from the side plate 21, and the lower end of each movable plate 3 extends between the cabinet body 2 and the side plate 21. A barb 32 is provided at the lower end of each movable plate 3, and the lower end of each movable plate 3 is hooked between a plurality of inverted teeth 210 provided on the side plate 21 by using the barb 32. The desktop panel 1 is fixed to the cabinet body 2 through the two movable plates 3 respectively cooperating with the corresponding side plates 21. Above; the two first swinging feet 4 and the two second swinging feet 5 swing outward in one direction along the corresponding axis respectively, and the two first swinging feet 4 and the two second swinging feet 5 are respectively arranged below the desktop panel 1; a placement groove is provided on one side of the cabinet 2, and the opening of the cabinet 2 is provided between the two side panels 21 and on the adjacent side, the drawer 6 is embedded in the cabinet 2, and moves back and forth to the placement groove of the cabinet 2; a storage box 7 is provided on both sides of the desktop panel 1 facing the two first swinging feet 4 and the two second swinging feet 5.

[0030] In the unfolded mode, the two second swinging feet 5 and the two first swinging feet 4 are turned outward, so that the desktop panel 1 and the cabinet body 2 are placed in an unfolded table, and supported by the two second swinging feet 5 and the two first swinging feet 4. At this time, it is necessary to adjust the tilt angle of the desktop panel 1 so that the outer surface of the desktop panel 1 is more suitable for the user's operation. By pulling the two toggle pieces 3 outward respectively, the lower parts of the two tilted toggle pieces 3 are swung backward, so that the hooks of the two toggle pieces 3 32 is separated from the hook between the two inverted teeth 210, and then, by pulling the two toggle pieces 3 upward and lifting one edge of the desktop panel 1 upward, when pulled to an appropriate tilt angle, the two toggle pieces 3 are released, and when the two toggle pieces 3 are not pulled outward, the lower ends of the two toggle pieces 3 are embedded between the other two inverted teeth 210 to achieve fixation. Therefore, when the two toggle pieces 3 are fixed in the two inverted teeth 210 at a certain height, the tilt angle can be adjusted.

[0031] After adopting the above structure, it needs to be further explained that each side panel 21 of the present invention and the side surface of the cabinet 1 are used to clamp a toggle piece 3. At the same time, the groove of the side panel 21 clamping the toggle piece 3 is the width presented by the swingable angle of the lower end of the toggle piece 3.

[0032] Each first swing foot 4 and each second swing foot 5 are fixed by two bosses of each side panel 21. In order to stack the first swing foot 4 and the second swing foot 5 on the side of the cabinet 2, the boss connecting the first swing foot 4 is longer than the boss connecting the second swing foot 5, and the thickness of the second swing foot 5 is the width of the gap between the first swing foot 4 and the side panel 21.

[0033] The desktop panel 1 is placed on top of the cabinet body 2; in the placement groove of the cabinet body 2, at least one guide ridge 22 is set on the upper surface, and a strip groove corresponding to the guide ridge 22 is opened on the side where the drawer 6 and the placement groove are in contact with each other, and the drawer 6 moves back and forth along the guide ridge 22 toward the opening direction of the placement groove.

[0034] After adopting the above structure, it needs to be further explained that a metal sheet is provided on one side of the drawer 6 and at the upper edge of the side that is pulled outward. The metal sheet is used for the lower surface of the desktop panel 1, and a magnet opposite to it provides magnetic attraction, so that during the transportation and placement process of the present invention, the drawer 6 can be prevented from sliding out due to external shaking.

[0035] The present invention has at least two guide ridges 22 which are arranged relatively parallel to each other. The arrangement of the two guide ridges 22 can prevent the drawer 6 from being offset when being pulled out and thus causing obstruction during pulling out, and also reduce the shaking of the drawer 6 inside the cabinet 2, thereby strengthening the stability of the drawer 6.

[0036] A paddle is provided extending outward from the upper end of each paddle plate 3; a protrusion is provided on a side of each fixed plate 31 away from the paddle plate 3, and is embedded in the desktop panel 1 through the protrusion; the fixed plate 31 passes through the desktop panel 1 to between the cabinet 2 and a side panel 21; an axle seat is provided at the opposite side edges of the fixed plate 31; the paddle plate 3 is provided between the two axle seats of the fixed plate 31, and the fixed plate 31 has a rotating shaft from one side of one axle seat to the other axle seat cross tube, and the rotating shaft crosses the paddle plate 3 between the two axle seats; a tension spring 211 is provided between the lower part of the paddle plate 3 and the fixed plate 31; the paddle plate 3 is engaged between each two inverted teeth 210 through the tension spring 211, and is arranged at an angle; the desktop panel 1 swings upward through two paddle plates 3 and at an edge adjacent to the two paddle plates 3.

[0037] After adopting the above structure, it needs to be further explained that the fixing plate 31 is fixed in the groove of the desktop panel 1 by embedding the protrusions. Therefore, the fixing plate 31 drives the desktop panel 1 to swing up and down by pulling the paddle piece 3.

[0038] In addition, the lower end of the fixed plate 31 extends to the groove between the side plate 21 and the opposite side of the cabinet 2. In order to ensure that the toggle piece 3 is not to be toggled by pressure applied from above, the lower end of the toggle piece 3 can drive the barb 32 to be engaged with the barbed tooth 210 of the side plate 21 to achieve fixation. The lower end of the toggle piece 3 and the fixed plate 31 are contacted by the relaxation spring 211 in the relaxed state, and the toggle piece 3 is pushed outward by the other end of the relaxation spring 211. When pressure is applied above the toggle piece 3 to toggle it, the relaxation spring 211 is squeezed to allow the toggle piece 3 to swing backward.

[0039] When the toggle plate 3 of the present invention is in an inclined state, it is horizontally connected through the two shaft seats and the above rotating shaft of the fixed plate 31, so that its inclined state is arranged in the form of an arch rod, so that when the toggle plate 3 is in an inclined state, one end of it is toggled and the other end realizes the opposite swing.

[0040] Each side panel 21 is fixed to one side of the cabinet 2 by screws; a lifting belt composed of a plurality of inverted teeth 210 is arranged in the groove of each side panel 21 and on one side facing the toggle plate 3, and the plurality of inverted teeth 210 are inclined along the upward swinging direction of the toggle plate 3 and are arranged and combined in sequence from top to bottom.

[0041] After adopting the above structure, it needs to be further explained that the inclination direction of several inverted teeth 210 is consistent with the swinging direction of the toggle plate 3, which can facilitate the hook 32 of the toggle plate 3 to be embedded in the gap between the two inverted teeth 210, avoiding the occurrence of loose fit, which causes the desktop panel 1 to fall down after being pressed from above.

[0042] The plurality of inverted teeth 210 are arranged in sequence from top to bottom, so that the barbs 32 can select the height positions for engagement in sequence from top to bottom. According to each different height, an edge of the desktop panel 1 is tilted upward, thereby forming different tilt angles.

[0043] One end of each first swing foot 4 adopts a rotating hole to cooperate with an axis column protruding outward from the side panel 21, and the first swing foot 4 is placed along the axis column to fit the lower surface of the desktop panel 1; the other end of each first swing foot 4 is provided with a storage box 41, and the storage box 41 is provided with a sliding groove on the side facing the side panel 21 and away from the first swing angle 4, and an ejector rod 42 is embedded in the sliding groove of the first swing foot 4, and a sliding convex edge is respectively provided on both sides of the ejector rod 42, and the two sliding convex edges of the ejector rod 42 are respectively embedded in the sliding groove, and the ejector rod 42 reciprocates in one direction along the sliding groove on the opposite sides; each ejector rod 42 is provided with an engaging belt 421 on the side facing the first swing foot 4, and a plurality of sliding convex edges along the ejector rod 42 are provided in the engaging belt 421 The ejection rod 42 extends long, and the fitting grooves are arranged in sequence; a transversely arranged movable groove is provided at the lower end of each first swing foot 4, and a covering plate 43 is provided on one side of the movable groove of the first swing foot 4, and an embedding plate 430 is laterally provided on the side of the covering plate 43 facing the movable groove, and the end of the embedding plate 430 away from the covering plate 43 is embedded in the fitting groove in the fitting belt 421, and a convex column is respectively provided at one end and on the opposite sides of the covering plate 43, and the covering plate 43 adopts two convex columns to be embedded in the first swing foot 4, and the covering plate 43 swings back and forth in one direction along the two convex columns, and the covering plate 43 is closely attached to one side of the first swing foot 4 and is connected to a pulling spring, and the pulling spring connected to the covering plate 43 is embedded in the corresponding circular groove opened in the first swing foot 4.

[0044] After adopting the above structure, it needs to be further explained that the two first swing legs 4 are used to adjust the two front support points of the present invention in the unfolded state, and when each first swing leg 4 is placed downward, the ejection rod 42 in the storage box 41 can be extended downward to adjust the height of the present invention.

[0045] Furthermore, the two first swinging feet 4 can independently adjust the extension length of the ejection rod 42, so that the present invention can be placed flat on an uneven ground.

[0046] When the extended length of the ejector rod 42 is changed, the covering plate 43 is moved, and the embedded plate 430 is separated from the outside from one of the several engaging grooves in the engaging belt 421 through the covering plate 43, so that the connection between the ejector rod 42 and the storage box body 41 is cancelled. At this time, the ejector rod 42 can be pulled outward. After being pulled out to the required length, the moving of the covering plate 43 is released, and the covering plate 43 is reset by pulling the spring. The reset pulling force allows the covering plate 43 to insert the engaging plate 430 into the engaging groove, thereby realizing the height limit of the ejector rod 42.

[0047] When the first swing leg 4 is stored, the above steps can be repeated to store the entire ejector rod 42 into the sliding groove, and the engaging plate 430 is engaged with the engaging groove at the end of the engaging belt 421 to fix the ejector rod 42 in the sliding groove.

[0048] Each second swing foot 5 is arranged between the side panel 21 and the first swing foot 4, and each second swing foot 5 swings back and forth in one direction along another convex column arranged on the side panel 21, and the second swing foot 5 is in contact with the lower surface of the desktop panel 1; a sliding opening is arranged below each second swing foot 5, and a moving plate 51 is embedded in the sliding opening of the second swing foot 5, and the moving plate 51 moves back and forth in one direction in the sliding opening of the second swing foot 5; a pushing groove is arranged at the upper end of each moving plate 51 and at an edge in contact with the sliding opening, an insertion block 53 is embedded in the moving groove of the moving plate 51, and a sliding convex strip is arranged at an edge of the moving plate 51 adjacent to the insertion block 53, and the second swing foot 5 is tightly connected to the side provided with the sliding convex strip The movable plate 51 is attached to the side plate 21 and is provided with a guide groove matching the sliding convex strip, and the movable plate 51 reciprocates along the extending direction of the guide groove of the first swing foot 5 through the sliding convex strip; a plurality of insertion grooves are provided in the guide groove of each movable plate 51 from top to bottom, and the insertion block 53 provided on the movable plate 51 is inserted into an insertion groove; a swinging protrusion 531 is provided above each insertion block 53, and is embedded in the upper edge of the sliding opening of the second swing foot 5, and a connecting groove corresponding to the swinging protrusion 531 is provided at the upper edge of the sliding opening of the second swing angle 5; a bayonet groove 52 is provided below each movable plate 51 and on the side opposite to the guide groove, and the bayonet groove 52 is wrapped around the outside of the convex column between the side plate 21 and the first swing foot 4.

[0049] After adopting the above structure, it needs to be further explained that the two second swing legs 5 are used to provide two rear fulcrums when the present invention is in the unfolded state, and after each second swing leg 5 is unfolded outward, the movable plate 51 can be pulled downward, thereby adjusting the height of the two rear fulcrums of the present invention.

[0050] When the height of each second swing foot 5 needs to be adjusted, the movable plate 51 is pulled downward until it is pulled out to the required position. After being pulled out, the insertion block 53 is pushed into the guide groove by pushing the swing protrusion 532 until the insertion block 53 is inserted into an insertion groove, thereby achieving the fixing of the moving position of the movable plate 51.

[0051] When the second swing foot 5 is in the stored state, it is stored between the side panel 21 and the first swing foot 4, and the bayonet slot 52 provided on the second swing foot 5 is used to reserve space for the boss connected to the first swing foot 4 when the second swing foot 5 is folded, so as to avoid damage to the boss due to collision.

[0052] Each first swing foot 4 and each second swing foot 5 swing downwards respectively and spread outwards respectively; the top of each first swing foot 4 and each swing foot 5 and the end connected to the boss are arranged in a semicircle, and a limit block 8 is provided on the semicircular edge of each first swing foot 4 and each swing foot 5, and each first swing foot 4 and each swing foot 5 are respectively placed on the lower surface of the desktop panel 1 using the limit block 8.

[0053] After adopting the above structure, it needs to be further explained that when the first swing foot 4 and the second swing foot 5 swing outward, the first swing foot 4 and the second swing foot 5 will be tilted outward by 10° respectively in the vertical direction. This setting can avoid the instability of the present invention when the first swing foot 4 and the second swing foot 5 are vertical. When the first swing foot 4 and the second swing foot 5 are tilted outward and opened respectively, a trapezoidal structure with both sides tilted can be provided, making the present invention more stable in the unfolded state.
