[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: A multifunctional desk, such as Figure 1 and Figure 2 As shown, it includes a desk 1, a table top 2, an extension mechanism 4 and a barrier mechanism 5. The table top 2 is placed on the inner upper side of the desk 1, and the extension mechanism 4 is provided on the inner lower side of the desk 1. The extension mechanism 4 is used to provide people with an additional dining platform. The table top 2 is provided with a barrier mechanism 5, which is used to block splashed oil and prevent it from sticking to office supplies or documents.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the expansion mechanism 4 includes an electric push rod 41, a lifting frame 42, a first slide bar 43, a space cam 44, a guide frame 45 and a first rotating frame 46. The rear side of the lower part of the desk 1 is connected to the electric push rod 41, and the upper side of the telescopic rod of the electric push rod 41 is connected to the lifting frame 42. The lifting frame 42 is slidably connected to the desk 1. The lifting frame 42 is made of a smooth material. The left and right sides of the lower part of the table board 2 are connected to the first slide bar 43. The first slide bar 43 is slidably connected to the lifting frame 42. The rear side of the lifting frame 42 is rotatable. A first rotating frame 46 is connected, the upper side of the first rotating frame 46 is movably connected to the table top 2, the lower side of the first rotating frame 46 is connected to the space cam 44, and the rear side of the lower inner part of the office desk 1 is connected to a guide frame 45, the guide frame 45 and the space cam 44 are slidably matched through a threaded groove, and the first rotating frame 46 is rotated through the extrusion fit of the threaded groove on the guide frame 45 and the space cam 44, so that the table top 2 can be moved backwards so that it is not blocked above the lifting frame 42, making it convenient for people to dine on the lifting frame 42.

[0033] like Figure 1 and Figure 5 As shown, the barrier mechanism 5 includes a connecting frame 51, a transparent plate 52, a second sliding rod 53 and a rotating rod 54. The left and right sides of the front of the table top 2 are slidably connected to the second sliding rod 53, the lower sides of the second sliding rod 53 are connected to the connecting frame 51, the front side of the connecting frame 51 is connected to the transparent plate 52 for shielding splashed oil, the left and right sides of the rear of the connecting frame 51 are rotatably connected to the rotating rod 54, and the rotating rod 54 is squeezed and fitted with the lifting frame 42.

[0034] When using the multifunctional office desk, people can place office tools and documents on the table top 2, and can also work on the table top 2. When people need to have a meal, they can start the electric push rod 41, so that the telescopic rod of the electric push rod 41 gradually extends upward, driving the lifting frame 42 to move upward, so that the first rotating frame 46 also moves upward, driving the space cam 44, the table top 2, the first sliding rod 43 and the computer display screen 3 to move upward. When the inflection point of the threaded groove on the space cam 44 moves to contact with the guide frame 45, under the extrusion of the guide frame 45, the space cam 44 will rotate clockwise by approximately 45°, so that the first rotating frame 46 will rotate accordingly, and the first rotating frame 46 will squeeze the table top 2, so that the table top 2 can move backward, driving the computer display 3 The screen 3 also moves backward, so that the table top 2 will not block the top of the lifting frame 42, that is, the lifting frame 42 will be exposed, thereby providing people with a dining space, avoiding people from dining on the table top 2 and causing oil and impurities to contaminate the computer display screen 3 or documents, that is, it can be more convenient for people to use. When the space cam 44 can no longer rotate, the electric push rod 41 is turned off. At the same time, when the table top 2 moves upward, it will also drive the second sliding rod 53 to move upward, so that the connecting frame 51, the transparent plate 52 and the rotating rod 54 also move upward. When the table top 2 moves backward, the connecting frame 51, the second sliding rod 53, the transparent plate 52 and the rotating rod 54 will also move backward, that is, relative to the rotating rod 54, it is the lifting frame 42 that moves forward. The lifting frame 42 will squeeze the rotating rod 54, causing the rotating rod 54 to gradually move upward and rotate appropriately, so that the connecting frame 51 also moves upward, driving the second sliding rod 53 and the transparent plate 52 to move upward as well, so that the transparent plate 52 will gradually block the front side of the table board 2, which is equivalent to using the transparent plate 52 to erect a transparent wall on the front side of the table board 2, so that the table board 2 can be protected by the transparent plate 52, so that people can watch the computer display screen 3 through the transparent plate 52 while avoiding oil and impurities splashing onto the documents on the table board 2, so that it can also be more convenient for people to use the multifunctional office desk. At this time, people can dine on the lifting frame 42, so that the dining area can be separated from the office area, preventing oil and impurities from dirtying the table The documents and office tools on the board 2 can be easily removed, and people do not need to organize documents or go to other places for meals, so that the multifunctional desk can be more convenient for people to use. When the meal is over, people can start the electric push rod 41 again, and the telescopic rod of the electric push rod 41 can be retracted and reset downward, driving the lifting frame 42 to move downward and reset, so that the first slide bar 43, the space cam 44 and the first rotating frame 46 can also move downward and reset, driving the table board 2 and the computer display screen 3 to move downward and reset accordingly, and under the squeezing of the guide frame 45, the space cam 44 will first rotate in the opposite direction to reset, so that the first rotating frame 46 can rotate in the opposite direction to reset, and the first rotating frame 46 will squeeze the table board 2 in the opposite direction, so that the table board 2 moves forward and resets, driving the computer display screen 3 to move forward and reset as well.The table top 2 will also make the connecting frame 51, the transparent plate 52, the second slide bar 53 and the rotating rod 54 move downward and forward to reset, and the lifting frame 42 will no longer squeeze the rotating rod 54, so that the connecting frame 51, the second slide bar 53 and the transparent plate 52 move downward and reset under the action of their own gravity, and the rotating rod 54 rotates in the opposite direction to reset. When the lifting frame 42 is reset, the electric push rod 41 is closed. In summary, you can eat through this multifunctional office desk.

[0035] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 6 As shown, a stabilizing mechanism 6 is also included, which includes a support frame 61, a second rotating frame 62, a lifting rod 63, a spring 64 and a guide plate 65. The rear side of the upper part of the table board 2 is connected to the support frame 61, and the second rotating frame 62 is rotatably connected to the support frame 61. The front side of the second rotating frame 62 is made of soft material, and the lifting rod 63 is slidably connected to the rear side of the support frame 61. The upper side of the lifting rod 63 is movably connected to the second rotating frame 62. A spring 64 is wound between the upper side of the lifting rod 63 and the rear upper side of the support frame 61. The spring 64 is wound on the lifting rod 63, and the rear upper side of the lifting frame 42 is connected to the guide plate 65. The guide plate 65 is in an inclined state with the front higher and the rear lower. The guide plate 65 is squeezed and matched with the lifting rod 63, and the lifting rod 63 moves downward under the action of the spring 64, so that the second rotating frame 62 moves downward and rotates appropriately, and the computer display screen 3 is pressed by the second rotating frame 62, so that the computer display screen 3 can be made more stable.

[0036] In the initial state, the guide plate 65 squeezes the lifting rod 63, and the spring 64 is in a stretched state. When the lifting frame 42 and the table board 2 move upward, the lifting frame 42 will drive the guide plate 65 to move upward, and the table board 2 will drive the support frame 61 and the lifting rod 63 to move upward, so that the second rotating frame 62 also moves upward. When the table board 2 moves backward, it will drive the support frame 61, the second rotating frame 62 and the lifting rod 63 to move backward. The lifting rod 63 will gradually no longer be squeezed by the guide plate 65. Under the action of the spring 64, the lifting rod 63 will gradually move downward, and the lifting rod 63 will squeeze the second rotating frame 62, so that the second rotating frame 62 moves downward and rotates appropriately. When the front side of the second rotating frame 62 contacts the computer display screen 3, since the front side of the second rotating frame 62 is made of soft material, the front side of the second rotating frame 62 will be appropriately deformed, so that the second rotating frame 62 can be The front side of the rotating frame 62 is more closely pressed against the top of the computer display screen 3, so that the computer display screen 3 is more stable when moving and prevents it from shaking and falling. It can save people the step of manually fixing the computer display screen 3, which makes it more convenient for people to use the multifunctional office desk. When the table top 2 moves forward and resets, it will drive the support frame 61, the second rotating frame 62 and the lifting rod 63 to move forward and reset. The guide plate 65 will gradually squeeze the lifting rod 63, so that the lifting rod 63 moves upward and resets. The spring 64 is stretched and reset, and the lifting rod 63 will squeeze the second rotating frame 62, so that the second rotating frame 62 moves upward and rotates in the opposite direction to reset. The front side of the second rotating frame 62 will stretch and reset under the action of its own elasticity. When the lifting frame 42 and the table top 2 move downward and reset, the support frame 61, the second rotating frame 62, the lifting rod 63 and the guide plate 65 will also move downward and reset.

[0037] like Figure 1 , Figure 7 and Figure 8 As shown, a cleaning mechanism 7 is also included, and the cleaning mechanism 7 includes a rotating shaft 71, a scraper 72 and a torsion spring 73. The rotating shaft 71 is connected between the left and right sides of the front of the table top 2. The scraper 72 used for scraping off oil and impurities adhering to the transparent plate 52 is rotatably connected to the rotating shaft 71. The scraper 72 is attached to the transparent plate 52, and torsion springs 73 are wound between the left and right sides of the upper part of the scraper 72 and the rotating shaft 71. The torsion springs 73 are all wound around the rotating shaft 71.

[0038] Sometimes oil and impurities may splash onto the transparent plate 52, affecting people's viewing of the computer display screen 3 through the transparent plate 52. Therefore, a scraper 72 is provided. When the transparent plate 52 moves up and down, the oil and impurities on the transparent plate 52 may be squeezed onto the scraper 72, causing the scraper 72 to rotate slightly and the torsion spring 73 to be slightly twisted. In this way, the surface of the transparent plate 52 can be scraped and cleaned by the scraper 72. When the oil and impurities are scraped off, the scraper 72 will rotate in the opposite direction and reset under the action of the torsion spring 73, and the torsion spring 73 will apply a squeezing force to the scraper 72, so that the scraper 72 can fit the transparent plate 52 more closely, so that the oil and impurities on the transparent plate 52 can be better scraped and wiped clean by the scraper 72, which can save people the step of manually wiping and cleaning the transparent plate 52, thereby making it easier for people to use the multifunctional office desk.

[0039] like Figure 1 and Fig. 9 As shown, a restraining mechanism 8 is also included, and the restraining mechanism 8 includes a supporting ring 81, a telescopic tube 82 and a connecting tube 83. The rear side of the left part of the desk 1 is connected to the supporting ring 81, the upper side of the supporting ring 81 is connected to the telescopic tube 82, the upper side of the telescopic tube 82 is connected to the connecting tube 83, and the lower right side of the connecting tube 83 is connected to the table top 2. By passing the wires through the telescopic tube 82 and the connecting tube 83, the wires are stored and restrained to prevent the wires from being messy.

[0040] When people need to connect wires, they can pass the wires through the support ring 81 and the telescopic tube 82 from bottom to top, then extend them through the connecting tube 83, and then connect the wires to the corresponding equipment, so that the wires can be restrained by the support ring 81, the telescopic tube 82 and the connecting tube 83 to prevent the wires from being placed randomly and causing the surface of the table top 2 to be messy, that is, the surface of the table top 2 can be made neater, so that it can be more convenient for people to use this multifunctional office desk for office work. When the table top 2 moves upward, it will drive the connecting tube 83 to move upward as well, and the telescopic tube 82 will be appropriately extended. When the table top 2 moves downward to reset, it will drive the connecting tube 83 to move downward to reset, and the telescopic tube 82 will shrink and reset.

[0041] like Figure 1 and Fig.10 As shown, a wiping mechanism 9 is also included, which includes a guide rod 91, a sliding frame 92 and a sponge block 93. The guide rod 91 is connected between the left and right sides of the lifting frame 42, and the sliding frame 92 is slidably connected to the guide rod 91. The lower side of the sliding frame 92 is connected to a sponge block 93 for wiping the lifting frame 42, and the lower side of the sponge block 93 is in contact with the lifting frame 42.

[0042] When people finish their meal on the lifting frame 42, they can move the sliding frame 92 to the left, so that the sponge block 93 also moves to the left. When the sliding frame 92 can no longer move to the left, the sliding frame 92 is moved to the right to reset, driving the sponge block 93 to move to the right to reset, so that the lifting frame 42 can be wiped back and forth by the sponge block 93. The lifting frame 42 is made of smooth material, which makes it easier for the sponge block 93 to wipe the lifting frame 42 clean, so that it is convenient for people to use the multifunctional office desk for dining next time.
