[0037] Example 1

[0038] A desk with folding function for easy organization, referring to Figure 1-4As shown, it includes a placement plate 1, a first connecting frame 2, a fixed plate 21, a rotating plate 22, a second connecting frame 3, a connecting rod 4, a retaining ring 5, a locking mechanism 6 and a supporting mechanism 7. The first connecting frame 2 is fixedly connected to the right side of the bottom of the placement plate 1 by bolts. The placement plate 1 is used to place items for office work. A connecting rod 4 is movably provided on the upper side of the first connecting frame 2. A second connecting frame 3 is welded to the right end of the connecting rod 4. An identical placement plate 1 is fixedly connected to the top of the second connecting frame 3 by bolts. A retaining ring 5 is welded to the middle part of the connecting rod 4. A fixed plate 21 is welded symmetrically to the outside of the bottom of the placement plate 1. A rotating plate 22 is rotatably provided on the fixed plate 21. The rotating plate 22 supports the placement plate 1. A locking mechanism 6 is provided on the left side of the connecting rod 4. A supporting mechanism 7 is provided on the placement plate 1. The supporting mechanism 7 can fix the rotating plate 22.

[0039] Reference Figure 4 As shown, the locking mechanism 6 includes a first sliding sleeve 61, a locking rod 62 and a first spring 63. The first sliding sleeve 61 is symmetrically provided on the left side of the connecting rod 4 by welding. The middle part of the first sliding sleeve 61 is slidably provided with a locking rod 62. The inner side of the locking rod 62 is connected to the adjacent first sliding sleeve 61 with a first spring 63. The upper and lower sides of the first connecting frame 2 are symmetrically provided with locking holes that match the locking rod 62.

[0040] Reference Figure 5 , Figure 6 and Figure 7 As shown, the supporting mechanism 7 includes a torsion spring 73, a second sleeve 74, a locking plate 75 and a second spring 76. The torsion spring 73 is symmetrically connected between the rotating plate 22 and the adjacent fixed plate 21. The second sleeve 74 is symmetrically welded on the outer side of the bottom of the placing plate 1. The second sleeve 74 is located on the outer side of the fixed plate 21. A locking plate 75 is slidably provided on the second sleeve 74. The locking plate 75 can clamp the rotating plate 22. The second spring 76 is connected between the locking plate 75 and the adjacent second sleeve 74. The upper side of the rotating plate 22 is provided with a locking hole that fits with the locking plate 75.

[0041] When the desk is needed, the present desk can be used. The user can place items on the placement plate 1, so that the office can be done. Because the placement plate 1 is a plane, there is no baffle like other desks, and it is also easy to organize the items on the desk. Initially, the torsion spring 73 is in a deformed state. When the desk is not needed, the user can press the positioning rod 62 to move inward, and the first spring 63 is stretched, and then the right placement plate 1 can be pulled to move to the right. The right placement plate 1 moves to the right, driving the second connecting frame 3, the connecting rod 4, the first sliding sleeve 61, the positioning rod 62, and the first spring 6 When the second spring 76 is pressed against the stopper 74, the locking plate 75 is released, and the locking plate 75 is pressed against the stopper 74. When the second connecting frame 3, the connecting rod 4, the first sliding sleeve 61, the locking rod 62, the first spring 63 and the retaining ring 5 are moved downward, and when the locking rod 62 moves to fit with the locking hole on the lower side, the locking rod 62 moves outward and is locked in the locking hole on the lower side under the action of the first spring 63. At this time, the right placing plate 1 can be rotated to the left, so that the two placing plates 1 can be folded together, which is convenient for storage. When it needs to be used again, the right placing plate 1 is first rotated in the opposite direction to reset it, and then the locking rod 62 is pressed again to move inward, and the first spring 63 is pressed again to move inward. When the spring 63 is stretched, the right placement plate 1 can be pulled upward first, and then the right placement plate 1 can be pushed to the left to reset. The retaining ring 5 can then resist the first connecting frame 2, which means that it has moved to the initial position. At this time, under the action of the first spring 63, the locking rod 62 moves outward and is locked into the upper locking hole. The user can rotate the rotating plates 22 away from each other to a vertical shape. The torsion spring 73 is deformed, and under the action of the second spring 76, the locking plate 75 moves inward and is locked into the locking hole of the rotating plate 22. In this way, the rotating plate 22 can be fixed, and it can be used for office work again.

[0042] Example 2

[0043] Based on Example 1, Figure 2 , Figure 8 , Fig. 9 and Fig.10As shown, it also includes a scraping mechanism 8, which can scrape dust off the surface of the placement plate 1. The scraping mechanism 8 includes a connecting plate 81, a first sliding plate 82, a third spring 83, a second sliding plate 84, a fourth spring 85, a driving rod 86 and an inclined rod 87. The bottom of the placement plate 1 is symmetrically provided with a connecting plate 81 by welding. The inner side of the connecting plate 81 is slidably provided with a first sliding plate 82. The first sliding plate 82 and the adjacent connecting plate 81 are connected with a third spring 83. The first sliding plates 82 on the left and right sides are slidably connected to each other. There is a second sliding plate 84, which can scrape off dust on the surface of the placement plate 1 when it moves outward. A fourth spring 85 is connected between the second sliding plate 84 and the adjacent first sliding plate 82. A driving rod 86 is symmetrically welded at the bottom of the right second sliding plate 84. An inclined rod 87 is symmetrically fixed to the right side of the bottom of the left placement plate 1 by bolts. The driving rods 86 are in contact with the adjacent inclined rods 87. The driving rods 86 are in contact with the second sliding plate 84 on the left. A slot that fits the second sliding plate 84 is opened on the inner side of the placement plate 1.

[0044] When the two placement plates 1 are folded together, the third spring 83 is stretched initially, and the placement plate 1 on the right side moves to the right, causing the driving rod 86 and the connecting plate 81, the first sliding plate 82, the third spring 83, the second sliding plate 84 and the fourth spring 85 on the right side to move to the right. When the driving rod 86 moves to the right, it will move upward under the action of the inclined rod 87, and the driving rod 86 moves upward to drive the second sliding plate 84 to move upward, and the fourth spring 85 is compressed, and the second sliding plate 84 moves upward and disengages from the slot of the placement plate 1. Under the action of the third spring 83 on the right side, the driving rod 86 and the first sliding plate 82, the second sliding plate 84 and the fourth spring 85 on the right side move to the right, and under the action of the third spring 83 on the left side, the first sliding plate 82, the second sliding plate 84 and the fourth spring 85 on the left side move to the left. The second sliding plate 84 moves to remove the dust on the placement plate 1. The folding work of the placement plate 1 can then be started. When the office desk needs to be used again, after the placement plate 1 is unfolded and reset, the second sliding plate 84 on the right can be pulled to move to the left, so that the driving rod 86 and the first sliding plate 82 and the fourth spring 85 on the right all move to the left, and the third spring 83 on the right is stretched. When the second sliding plate 84 on the right moves to fit with the slot of the placement plate 1 on the right, the driving rod 86 and the second sliding plate 84 on the right are moved downward and reset under the action of the fourth spring 85 on the right, and then the second sliding plate 84 on the left can be pulled to drive the fourth spring 85 and the first sliding plate 82 to move to the right, and the third spring 83 on the left is stretched. When the second sliding plate 84 on the left moves to fit with the slot of the placement plate 1 on the left, the second sliding plate 84 on the left is moved downward and reset under the action of the fourth spring 85 on the left.

[0045] Reference Figure 2 , Fig.11 and Fig.12 As shown, it also includes an adjusting mechanism 9, which can adjust the height of the placement plate 1. The adjusting mechanism 9 includes a third sliding plate 91, a third sliding sleeve 92, a sliding rod 93 and a fifth spring 94. The third sliding plate 91 is slidably provided on the rotating plate 22. The third sliding sleeve 92 is welded on the upper outer side of the third sliding plate 91. The sliding rod 93 is slidably provided in the middle of the third sliding sleeve 92. The sliding rod 93 can clamp the position of the rotating plate 22. The fifth spring 94 is connected between the sliding rod 93 and the adjacent third sliding sleeve 92. The sliding rod 93 is slidably connected to the adjacent third sliding plate 91. Five sliding holes that fit with the sliding rod 93 are opened on the rotating plate 22, and the spacing between every two adjacent sliding holes is 10 cm.

[0046] When the present office desk is in use, if the user feels that the height of the placement plate 1 is not high enough, the user can also adjust the height of the placement plate 1 as needed. The user can pull the sliding rod 93 to move outward, and the fifth spring 94 is stretched. Then the rotating plate 22 can be pulled to drive the fixed plate 21 and the placement plate 1 to move upward. When the rotating plate 22 moves to a suitable position and the sliding hole is aligned with the sliding rod 93, the sliding rod 93 can be released. Under the action of the fifth spring 94, the sliding rod 93 moves inward and is stuck in the sliding hole of the rotating plate 22. In this way, the rotating plate 22 can be fixed. Moreover, because the spacing between the sliding holes is 10 cm, it is also convenient for the user to know how much he has adjusted the height of the placement plate 1.

[0047] Reference Figure 2 , Fig.13 and Fig.14 As shown, it also includes a driving mechanism 10, which can make the rotating plate 22 rotate automatically. The driving mechanism 10 includes a first driving plate 101, a second driving plate 102 and a third driving plate 103. The first driving plate 101 is welded on the left-side clamping plate 75, and the second driving plate 102 is welded on the right-side clamping plate 75. The third driving plate 103 is symmetrically fixed to the right side of the bottom of the left-side placing plate 1 by bolts. The third driving plate 103 can contact the second driving plate 102, and the third driving plate 103 is on the left side of the inclined rod 87.

[0048] When the placement plate 1 on the right moves to the right, it will drive the second driving plate 102 to move to the right, and then when the placement plate 1 on the right drives the second driving plate 102 to move downward, under the action of the third driving plate 103, the second driving plate 102 drives the right locking plate 75 to move to the right to release the right rotating plate 22, and when the placement plate 1 on the right moves downward, it squeezes the first driving plate 101 to drive the left locking plate 75 to move to the left to release the left rotating plate 22. In this way, when the placement plate 1 is folded, the rotating plate 22 will automatically rotate. When the office desk is used again, the left locking plate 75 can drive the first driving plate 101 to move to the right and reset, and the right locking plate 75 can drive the second driving plate 102 to move to the left and reset.

[0049] Reference Figure 2 , Fig.15 and Fig.16 As shown, it also includes a fixing mechanism 11, which can be fixed when the two placement plates 1 are rotated close to each other, and the fixing mechanism 11 includes a locking rod 1101, a third connecting frame 1102, a locking plate 1103 and a sixth spring 1104. The locking rod 1101 is fixedly connected to the middle of the bottom of the left placement plate 1 by bolts, and the third connecting frame 1102 is fixedly connected to the right side of the bottom of the right placement plate 1 by bolts. A locking plate 1103 is slidably provided in the middle of the third connecting frame 1102, and the locking plate 1103 can be clamped by the locking rod 1101. The sixth spring 1104 is connected between the right side of the locking plate 1103 and the third connecting frame 1102.

[0050] When the two placing plates 1 are folded together, the placing plate 1 on the right side rotates to drive the third connecting frame 1102, the locking plate 1103 and the sixth spring 1104 to rotate. When the locking plate 1103 rotates to contact the locking rod 1101 and continues to rotate, the locking plate 1103 will move to the right under the action of the locking rod 1101, and the sixth spring 1104 will be stretched. When the locking plate 1103 passes over the locking rod 1101, the locking plate 1103 moves to the left and resets under the action of the sixth spring 1104. In this way, the two placing plates 1 can be fixed together by the locking plate 1103 and the locking rod 1101 to prevent the folded placing plates 1 from rotating away from each other due to external force. When the office desk needs to be used again, the locking plate 1103 can be pulled to the right, the sixth spring 1104 can be stretched, and then the placing plate 1 on the right side can be rotated, and the locking plate 1103 is released. Under the action of the sixth spring 1104, the locking plate 1103 moves to the left and resets.

[0051] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
