Description

Technical Field

[0001] The utility model belongs to the technical field of learning auxiliary tools, and in particular relates to a learning table that is convenient to use. Background Art

[0002] The study desk is a tool made through in-depth research on the three major disciplines of ergonomics, human mechanics and human physiology, combined with human visual principles, color science, psychology, etc., after countless data collection, experiments and demonstrations. The study desk and the traditional desk are two completely different concepts.

[0003] Most of the common study desks on the market now have adjustable tabletop heights so that they can be adjusted accordingly according to the actual height of the students using them. However, during the learning process, students sometimes need to hold onto books to read. As the reading time increases, students' eyes will unconsciously move closer to the books, which will not only cause eye fatigue due to the close reading distance, but will also make the sitting posture non-standard, affecting physical development.

[0004] In addition, during the learning process, students sometimes need to refer to multiple books or multiple materials for reading and learning. When the desktop is small, some books or materials are closed and opened when they need to read. This is inconvenient. If the desktop area is increased, the space occupied by the desk itself will increase. And when more books are placed on the study desk, they can only be stacked one by one, which is inconvenient to take. There are also study desks with bookshelves in the prior art, but the books are not fixed and are easy to slide down to the desktop. These problems also need to be optimized and improved. Summary of the invention

[0035] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0036] See also Figure 1 and Figure 2 A specific embodiment of a convenient study table includes table legs, and a horizontal supporting platform 1 is installed on the upper end of the table legs; a pallet 2 and a table top 3 are provided on the supporting platform 1; the pallet 2 is slidably connected to the upper surface of the supporting platform 1 and can slide back and forth along the width direction of the supporting platform 1, and a locking structure is provided between the pallet 2 and the supporting platform 1 to lock the relative position of the pallet 2 and the supporting platform 1 after the pallet 2 slides into place; the front side of the table top 3 is rotatably connected to the pallet 2 through a rotating shaft 4, and a toothing structure is provided between the table top 3 and the rotating shaft 4 to constrain the table top 3 to keep the rotation angle unchanged.

[0037] The embodiment is a convenient study table, in which the desktop of the study table is designed to be a supporting platform 1, a supporting plate 2 and a table top 3 from bottom to top, the supporting plate 2 and the supporting platform 1 are slidably connected, and the table top 3 and the supporting plate 2 are rotatably connected; in this way, the area of ​​the entire desktop can be expanded by sliding the supporting plate 2 back and forth to place more books and materials that need to be read; the table top 3 can be rotated to a suitable angle to enable students to maintain a good sitting posture and always keep a suitable distance from the books.

[0038] The front protrusion on the upper surface of the table top 3 is provided with a transverse flange for holding books.

[0039] In this way, the user does not need to hold the book with his hands.

[0040] See also Figure 1 and Figure 2 , wherein a strip groove 301 is vertically opened on the front side of the upper surface of the table board 3 along the length direction of the table board 3, and a book support plate 5 is arranged in the strip groove 301, and the book support plate 5 can be rotatably connected to the side wall located on the front side of the strip groove 301; the width of the book support plate 5 is adapted to the width of the strip groove 301 and is greater than the depth of the strip groove 301, and when the book support plate 5 is rotated to be perpendicular to the bottom wall of the strip groove 301, it forms the flange.

[0041] In this way, the flange of the table top 3 is designed to be in the form of the rotatable book support 5. When the table top 3 is in a horizontal state, the book support 5 can be hidden and stored in the strip groove 301. During implementation, the book support 5 is rotatably connected to the strip groove 301 through a book support shaft (not shown in the figure), and the length of the book support 5 is adapted to the length of the strip groove 301. A notch is provided on the side of the book support 5 away from the book support shaft so that the user can apply force through the notch to control the rotation of the book support 5.

[0042] See also Figure 3 and Figure 4 , wherein vertical shaft side plates 6 are provided on both sides of the support plate 2 corresponding to the positions of the shaft 4, and the table top 3 is located between the two shaft side plates 6;

[0043] The rotating shaft 4 moves along the length direction of the supporting platform 1 through the side of the table top 3 and is movably connected to the table top 3;

[0044] Both ends of the rotating shaft 4 are rotatably connected to adjacent rotating shaft side plates 6 ; the toothing structure is used to limit the relative rotation between the table top 3 and the rotating shaft 4 .

[0045] During implementation, the front side of the support plate 2 is also formed with a vertical section 201 that abuts against the table top 3. The front side of the table top 3 is a semicircular structure, and the rotating shaft 4 is coaxial with the center of the semicircular part of the front side of the table top 3; to avoid interference with the rotation of the table top 3.

[0046] Please continue to see Figure 3 and Figure 4 , wherein the gearing structure includes a locking side plate 41, which is disposed between the shaft side plate 6 at one end of the shaft 4 and the table top 3, and the portion of the shaft 4 opposite to the locking side plate 41 is a locking section 401; the other end of the shaft 4 away from the locking section 401 is a force-applying end 402;

[0047] The toothing structure further includes a spline tooth 42 and a spline groove matched with the spline tooth 42, wherein the spline tooth 42 is arranged on the outer surface of the shaft locking section 401; the spline grooves are respectively arranged on the side of the table top 3 opposite to the locking side plate 41 and on the side of the locking side plate 41 opposite to the table top 3;

[0048] Assume that the spline teeth 42 are simultaneously connected with the spline grooves of the table top 3 and the locking side plate 41 as state one; the spline teeth 42 are only connected with the spline grooves of the table top as state two; the spline teeth 42 can switch between state one and state two along the axial direction of the rotating shaft.

[0049] During implementation, a handle 43 is fixedly connected to the force-applying end 402 of the rotating shaft 4, which is used to pull the rotating shaft 4 to move axially to complete the conversion of the spline teeth 42 between state 1 and state 2. Figure 3 As shown, the handle 43 is designed to be cylindrical with a diameter larger than the rotating shaft 4, so that the handle 43 can be easily pulled outward.

[0050] Thus, since the shaft 4 and the table top 3 are movably connected, the shaft 4 can be moved left and right along the axis and can also be rotated; Figure 2-Figure 4 As shown, by pulling the handle 43 to the left, the entire shaft 4 (including the locking section 401) can be driven to move to the left, and the spline teeth 42 disengage from the locking side plate 41 and then only cooperate with the spline grooves of the table board 3. At this time, the shaft 4 and the table board 3 are in a fixed connection state (that is, the shaft 4 cannot rotate in the table board 3), and the spline teeth 42 are no longer cooperated with the spline grooves of the locking side plate 41, so the angle of the table board 3 can be adjusted; after the table board 3 is adjusted, push the handle 43 to the right, so that the spline teeth 42 cooperate with the spline grooves of the table board 3 and the locking side plate 41 at the same time, and the table board 3 does not move.

[0051] During implementation, the spline teeth 42 can be directly processed on the rotating shaft 4 or assembled on the rotating shaft 4 .

[0052] In the present utility model, the angle adjustment of the table board 3 is step-by-step adjustment, that is, the minimum angle value of the table board 3 rotation is consistent with the angle between two adjacent spline teeth 42; when adjusting the table board 3, the rear end of the table board 3 should be lifted and rotated around the rotating shaft 4, which is labor-saving. Of course, in order to further ensure the stability of the table board 3 when it is tilted, a support rod for supporting the table board 3 can be set between the table board 3 and the support plate 2. In the prior art, as disclosed in CN210960932U, the adjustment rod in this scheme is the support rod; of course, telescopic rods can also be set on both sides of the table board 3, which are all prior art. It is recommended to use a material with low density and high strength for the table board 3, such as a polyethylene sheet.

[0053] See also Figure 5 and Figure 6 , wherein a slide groove 101 is vertically opened on the upper surface of the support platform 1, and the length direction of the slide groove 101 is consistent with the width direction of the support platform 1;

[0054] A connecting plate 21 adapted to the slide groove 101 is connected to the rear side of the lower surface of the support plate 2 at a position corresponding to the slide groove 101 . The connecting plate 21 is located in the slide groove 101 so that the support plate 2 is slidably connected to the support platform 1 .

[0055] In this way, the support plate 2 can slide back and forth on the support platform 1 by controlling the connecting plate 21 to slide back and forth in the slide groove 101; during implementation, the length of the connecting plate 21 does not need to be very long, and it is only necessary to ensure that the connecting plate 21 is located as far as possible on the rear side of the support plate 2, so that the usable area of ​​the desktop can be expanded as much as possible.

[0056] The length of the slide groove 101 is smaller than the width of the support platform 1 , and the rear end of the slide groove 101 passes through the rear side of the support platform 1 .

[0057] In this way, it is convenient to install the support plate 2 on the supporting platform 1, and it can prevent the support plate 2 from sliding out of the slide groove 101 when the support plate 2 is pulled forward; during implementation, the slide groove 101 can also be a T-slot or a dovetail groove.

[0058] The locking structure includes an insertion rod 71, which moves through the connecting plate 21 in a direction perpendicular to the side of the supporting platform 1, and the inner end of the insertion rod 71 is fixedly connected to a limiting rod 72, and the limiting rod 72 is perpendicular to the insertion rod 71. A clearance groove 102 is vertically opened on the inner side of the slide groove 101 on the supporting platform 1, and the clearance groove 102 is parallel to the slide groove 101. The width of the clearance groove 102 is greater than or equal to the width of the limiting rod 72 so that the limiting rod 72 can slide in the clearance groove 102;

[0059] A plurality of vertical limiting grooves 103 are evenly spaced vertically inwardly on the side wall of the giving way groove 102 away from the slide groove 101, and the height of each limiting groove 103 is consistent with that of the giving way groove 102; the width of the notch of the limiting groove 103 is less than the length of the limiting rod 72 and is adapted to the thickness of the limiting rod 72, and the limiting rod 72 can slide inwardly into the limiting groove 103 after rotating to the vertical position to lock the support plate 2 with the support platform 1;

[0060] The outer end of the insertion rod 71 extends out of the side of the support platform 1 and is fixedly connected to a gripping rod 73, and the gripping rod 73 is parallel to the limiting rod 72; a rod sliding groove 104 adapted to the insertion rod 71 is vertically opened on the side of the support platform 1 at the position corresponding to the insertion rod 71, and the length direction of the rod sliding groove 104 is consistent with the width direction of the support platform 1 so that the insertion rod 71 can slide back and forth along the support platform 1; the rod sliding groove 104 extends inwardly to be connected with the sliding groove 101 and the giving way groove 102 in sequence.

[0061] In this way, in the initial state, the limit rod 72 does not fall into the limit groove 103 but is in the clearance groove 102, and the forward and backward sliding of the support plate 2 on the support platform 1 can be controlled by moving the handle 73 forward and backward; when sliding to a suitable position, the handle 73 is rotated to a vertical state, and the support plate 2 is moved forward and backward. Figure 6 In the embodiment, the rotation direction is clockwise, so that the limiting rod 72 is vertical, and then the gripping rod 73 is pushed inward along the axial direction of the insertion rod 71, so that the limiting rod 72 falls into the limiting groove 103, thereby realizing the positioning of the support plate 2 on the supporting platform 1.

[0062] During implementation, in order to facilitate the processing of the plurality of limit grooves 103, as shown in FIG. Figure 5 As shown, each limiting groove is a long strip component with a notch, which is assembled in the clearance groove 102. It only needs to ensure that the width of the clearance groove 102 can be assembled and leave a distance for the limiting rod 72 to slide in the clearance groove 102.

[0063] In this embodiment, since the cross section of the slide groove 101 is square, and the insertion rod 71 is connected to the middle position of the limiting rod 72, the support plate 2 will be pushed up in any direction when the handle rod 73 is rotated from the initial state. In order to avoid pushing the support plate 2 up, the upper end height of the give way groove 102 can be raised so that the height of the entire give way groove 102 is adapted to the length of the limiting rod 72, and at the same time, the distance between the axial direction of the insertion rod 71 and the lower surface of the support plate 2 is greater than half the length of the limiting rod 72;

[0064] The insertion rod 71 can also be connected to any free end of the limiting rod 72, and the upper end of the clearance groove 102 can be higher than the upper surface of the limiting rod 72 in the initial state. In this way, the slot height of the clearance groove 102 can be reduced, and the slide groove 101 can be further designed as a T-slot or a dovetail groove.

[0065] See also Figure 1 and Figure 2 , wherein a vertical back plate 87 is connected to the rear end of the upper surface of the support platform 1, and the back plate 87 is perpendicular to the left and right side surfaces of the support platform 1; a first baffle 81 and a second baffle 82 are arranged on the front side surface of the back plate 87, and the first baffle 81 and the second baffle 82 are parallel to the left and right side surfaces of the support platform 1; a spring 83 is connected to the side of the first baffle 81 close to the second baffle 82, and the other end of the spring 83 is connected to a spring push plate 84, and the spring push plate 84 is parallel to the side surface of the support platform 1, and the spring 83 is compressed between the first baffle 81 and the spring push plate 84.

[0066] In this way, unused books are placed between the spring push plate 84 and the second baffle 82, and the books will not slide down under the action of the spring 83; Figure 1 As shown, a third baffle 85 is provided on the left side of the first baffle 81 , and a horizontal partition 86 is provided between the first baffle 81 and the third baffle 85 . The partition 86 can be used to place items and also serve as a reinforcing rib to provide support for the first baffle 81 .

[0067] In this embodiment, the area of ​​the support plate 2 is smaller than the area of ​​the entire support platform 1, and a plastic pad 9 is fixedly connected to the left side of the upper surface of the support platform 1. The plastic pad 9 is vertically provided with step holes for placing water cups and desk lamps.

[0068] The following is a further description of the method for using a convenient study table of the utility model:

[0069] First, the grip rod 73 can be adjusted forward and backward to adjust the front and rear positions of the support plate 2 and the table board 3 relative to the supporting platform 1. After the adjustment is completed, the grip rod 73 is rotated to a vertical state, and the grip rod 73 is pushed inward along the axial direction of the insertion rod 71 so that the limit rod 72 falls into the limit groove 103 to complete the positioning of the support plate 2 on the supporting platform 1; then the angle of the table board 3 is adjusted, and the handle 43 is pulled outward along the axial direction of the rotating shaft 4 so that the spline teeth 42 disengage from the locking side plate 41 and only cooperate with the spline groove of the table board 3, and the table board 3 is rotated to a suitable angle, and the handle 43 is pressed inward so that the spline teeth 42 are simultaneously cooperated with the locking side plate 41 and the spline groove of the table board 3, and the table board 3 remains stationary; finally, the book support plate 5 in the strip groove 301 is rotated to a state that it is perpendicular to the bottom wall of the strip groove 301, and the book can be placed on the book support plate 5 for reading and learning.

[0070] After use, turn the book support plate 5 back to the strip groove 301; pull the handle 43 outward to rotate the table top 3 to a horizontal state, press the handle 43 inward to fix the table top 3 and the locking side plate 41; pull the grip rod 73 outward to make the limit rod 72 located in the yield groove 102, push the support plate 2 forward to make the support plate 2 return to its original position, and then push the grip rod 73 in a vertical state to make the limit rod 72 located in the limit groove 103, thereby locking the relative position of the support plate 2 and the support platform 1.
