[0017] Since it is a one-sided table leg desk, only one of the upper ends of the table legs needs to be pulled vertically to move, and the connecting rod can drive the other table leg to move synchronously. The connecting rod is directly arranged between the two table legs in order not to occupy the aisle space, so that the table bucket can be avoided when the desk has a larger storage space, and the table bucket, the connecting rod and the table leg can be avoided by horizontal sliding, making the turning-over more stable.

[0018] The lower side of the inner end of the support strip is provided with a limiting opening, and the outer wall of the sliding rod is transversely abutted on the opening wall of the limiting opening after the sliding rod is turned over.

[0019] The limiting opening is arranged to enable the outer wall of the sliding rod to be transversely abutted on the opening wall of the limiting opening after the desktop is turned over by the sliding rod around the support shaft, thereby achieving transverse limiting of the turned-over desktop, enabling the desktop to be stably vertically arranged, and improving the stability of the positioning after turning over.

[0020] In the above-described reversible desk, the outer end surface of the sliding rod is a yielding surface arranged to be inclined outward from top to bottom, and the yielding surface is located outside the insertion hole when the support shaft abuts against the outer end of the strip-shaped hole.

[0021] The arrangement of the yielding surface avoids guiding and yielding of the sliding rod after moving out of the insertion hole for turning over, thereby making the turning over more smooth and stable.

[0022] In the above-described reversible desk, a fastener is connected to the support strip, a positioning hole is arranged on the sliding rod, and the fastener is inserted into the positioning hole when the outer end of the sliding rod is inserted into the insertion hole.

[0023] The arrangement of the structure enables the fastener to be inserted into the positioning hole, thereby achieving positioning of the outer end of the sliding rod and the support strip, achieving stable limiting of the sliding rod and the support strip by insertion limiting, and improving the convenience and stability of the positioning.

[0024] In the above-described reversible desk, a fastener is connected to the support strip, and the fastener is inserted into the support strip and threadedly connected with the support strip.

[0026] In the above-described reversible desk, the fastener is located on the side wall or bottom wall of the outer end of the support strip, and the rod part of the fastener is located outside the support strip.

[0027] The fastener can be located on the side wall or bottom wall of the outer end of the support strip, and the rod part of the fastener is located outside the support strip, so that the fastener can also be used for hooking, which is convenient for students to adjust when located on the side wall, and avoids being hung by students when located on the bottom wall, thereby improving the safety.

[0028] In the above-described reversible desk, a storage tray is arranged between the lower ends of the two legs.

[0029] The storage tray can also increase the storage space of the desk without affecting the aisle space, making it easier for students to use.

[0030] Compared with the prior art, this reversible desk has the following advantages:

[0031] 1. By setting the give-way opening, when the outer end of the sliding rod slides out of the plug-in hole laterally, the give-way opening gives way to the sliding rod, allowing the sliding rod to rotate around the support shaft. By setting the support shaft and the sliding rod plugged in the plug-in hole, the inner and outer ends of the support bar provide support to the sliding rod when the desk is in normal use, thereby realizing multi-point support for the table board, improving the pressure-bearing capacity and stability of the table board, and making the desk with single-sided legs have a folding function without affecting the stability of the desk with single-sided legs in normal use.

[0032] 2. Since it is a desk with single-sided legs, when the legs are extended or retracted vertically, you only need to pull the upper end of one of the legs to move vertically, and the connecting rod can drive the other leg to move synchronously. In order not to occupy the aisle space, the connecting rod is directly set between the two legs. Therefore, while ensuring that the desk drawer has a large storage space, the desk drawer can avoid the connecting rod and the legs by sliding horizontally first, making the flipping more stable.

[0045] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0046] Example 1

[0047] like Figure 1 As shown, the flip desk includes a table top 2 and at least one table leg 1. One side of the table top 2 is connected to the upper end of the table leg 1, and the other side of the table top 2 is suspended in the air. The lower end of the table top 1 is connected to the table drawer 3, and the upper ends of the two table legs 1 are connected by a connecting rod 13.

[0048] Specifically, if Figures 1-10 As shown, the upper end of the table leg 1 has a tubular support bar 11 arranged inwardly in the transverse direction, the outer end of the support bar 11 has a plug hole 11a opened in the transverse direction, and the upper side surface of the inner end is provided with a clearance opening 11b, and the table top 2 is connected to a sliding rod 21 arranged in the transverse direction, and the outer end of the sliding rod 21 can be inserted and fixed in the plug hole 11a; the sliding rod 21 is provided with a strip hole 21a arranged in the transverse direction, and the inner end of the support bar 11 is fixed with a support shaft 12, and the sliding rod 21 is inserted into the strip hole 21a and the support bar 1 through the support shaft 12. 1 is hinged, and the sliding rod 21 can also slide laterally so that its outer end is out of the plug-in hole 11a. The lower end of the table board 1 is connected to the table drawer 3. There are two table legs 1 and they are distributed along the front and rear directions. The upper ends of the two table legs 1 are connected by a connecting rod 13, and the connecting rod 13 is always located on the outside of the table drawer 3. The connecting rod 13 is always located on the outside of the table drawer 3. A fastener 4 is connected to the support bar 11, and a positioning hole 21c is opened on the sliding rod 21. When the outer end of the sliding rod 21 is inserted into the plug-in hole 11a, the fastener 4 is inserted into the positioning hole 21c.

[0049] In normal use, the outer end of the sliding rod 21 is inserted into the insertion hole 11a of the support strip 11, and the vertical positioning between the sliding rod 21 and the support strip 11 is achieved by embedding the end of the sliding rod 21 into the insertion hole 11a of the support strip 11 in a transverse manner, and the stable connection between the sliding rod 21 and the support strip 11 in normal use is achieved through the transverse positioning of the fastener 4. When a nap or storage of the desk is needed, the positioning of the sliding rod 21 by the fastener 4 is released, and then the sliding rod 21 is transversely slid along the support shaft 12, so that the outer end of the sliding rod 21 is out of the insertion hole 11a. The sliding rod 21 can be rotated downward around the support shaft 12 and make the table top 2 vertically arranged, so as to realize that the table top 2 is attached to the inner side of the table leg 1. At this time, the school chair part can be placed on the side of the desk without the table leg 1, and by means of part of the aisle space, the lying sleep can be realized without the cooperation of the front and rear desks, and the space utilization of the desk in lying sleep is improved. The above structure is achieved by the cooperation of the insertion hole 11a on the support strip 11 and the fastener 4, and the vertical and transverse positioning of the sliding rod 21 is achieved by the way of first insertion and then positioning. When the table top 2 needs to be turned over, the setting of the allowance opening 11b makes the sliding rod 21 be allowed when the outer end of the sliding rod 21 is transversely slid out of the insertion hole 11a, so that the sliding rod 21 is rotated around the support shaft 12. The setting of the support shaft 12 and the sliding rod 21 inserted into the insertion hole 11a makes the inner and outer ends of the support strip 11 provide support for the sliding rod 21 when the desk is normally used, so as to realize the multi-point support for the table top 2, improve the pressure bearing capacity and use stability of the table top 2, and make the desk with single side table leg have folding function without affecting the stability of the desk with single side table leg in normal use.

[0050] In actual use, the two desks with the turned over table top 2 can be inserted into each other to reduce the storage space and save the storage space of the desk when not in use, which is convenient for storage. The present application adopts the way of transverse sliding and then turning over, which can avoid the interference between the table leg 1 and the table bucket 3 in the turning over process when the table bucket 3 is connected below the table top 2, and also improves the stability of the turning over structure when there is a larger storage space.

[0051] As shown in Figures 3-6 The lower wall of the table top 2 and the upper wall of the outer end of the sliding rod 21 form an allowance gap 5. The sliding rod 21 is a square rod, and the support strip 11 is a square tube. The upper wall of the sliding rod 21 is attached to the upper wall of the insertion hole 11a, and the lower wall of the sliding rod 21 is attached to the inner wall of the support strip 11. The sliding rod 21 is U-shaped and fixed around the table top 2 in the circumferential direction. The two support strips 11 are arranged on the table leg 1 in the front and rear directions, and the two outer ends of the sliding rod 21 can be inserted into the corresponding support strips 11.

[0052] As shown in Figures 5-8As shown in the figure, a limiting opening 11c is formed in the lower side of the inner end of the support strip 11, and the sliding rod 21 can be partially located in the limiting opening 11c after being turned over, and the outer wall of the sliding rod 21 is horizontally abutted on the opening wall of the limiting opening 11c, and the outer end surface of the sliding rod 21 is a giving space surface 21b which is obliquely outward arranged from top to bottom, and the giving space surface 21b is located outside the inserting hole 11a when the support shaft 12 is abutted on the outer end of the strip-shaped hole 21a.

[0053] As shown in the figure, Figures 6-8 The fastener is located on the side wall or bottom wall of the outer end of the support strip 11, and the rod part of the fastener is partially located outside the support strip 11, and the lower end between the two table legs 1 is provided with a storage tray 6.
