DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] The utility model provides a technical solution: Figure 3 and Figure 4 As shown, in this embodiment, a lifting and stable office desk includes a mounting plate 1, which is characterized in that: a support column 2 is fixedly connected to the four corners of the bottom outer wall of the mounting plate 1, and a reinforcement component 4 is installed at the bottom of the four support columns 2. The reinforcement component 4 includes a mounting groove 401 opened on the outer wall of one side of the support column 2, and the inner walls at both ends of the mounting groove 401 are rotatably connected with a screw rod 402. A mounting groove 2 403 begins to be provided on the outer wall of the bottom of the support column 2, and an extension plate 404 is slidably connected in the mounting groove 2 403. The protruding end of the extension plate 404 is slidably connected in the mounting groove 1 401, and the extension plate 404 is threadedly connected to the outside of the screw rod 1 402, and a motor 1 405 is fixedly installed on the outer wall of one end of the support column 2, and the output end of the motor 1 405 is coaxially fixed with the screw rod 1 402, and the two screw rods 1 402 on one side are arranged in opposite rotation directions.
[0024] The two supporting columns 2 are rotatably connected with a same connecting shaft 407, and both ends of the connecting shaft 407 are coaxially fixed with one end of the two screw rods 402 respectively. Both connecting shafts 407 are fixedly sleeved with a pulley 408, and the two pulleys 408 are sleeved with the same belt 409.
[0025] A screw rod 402 connected to it is driven to rotate by a motor 405, and an extension plate 404 slidably connected in the installation groove 401 is restricted to translational movement, and the screw rod 402 can drive the extension plate 404 to move toward the outside of the installation groove 2 403. The screw rod 402 drives another screw rod 402 to rotate through the connecting shaft 407, and the connecting shaft 407 also drives the external pulley 408 to rotate synchronously. This pulley 408 can drive another pulley 408 to rotate through the belt 409, so the other two screw rods 402 will also rotate synchronously, and then the other extension plates 404 will move outward at the same time, and the supporting area of the office desk will be greatly increased.
[0026] like Figure 1 and Figure 2 As shown, a lifting assembly 5 is installed on the top of the mounting plate 1, and the lifting assembly 5 includes a limit frame 501 fixedly connected to the outer wall of the top of the mounting plate 1, and the inner walls on both sides of the limit frame 501 are rotatably connected to the same bidirectional screw rod 502, and both ends of the bidirectional screw rod 502 are threadedly connected to a moving block 503, and the two moving blocks 503 are slidably connected in the limit frame 501, and the tops of the two moving blocks 503 are rotatably connected to a top plate 504, and one end of the top of the two top plates 504 is rotatably connected to the same desktop 3.
[0027] A second motor 505 is fixedly mounted on the outer wall of one side of the limiting frame 501 , and the output end of the second motor 505 and one end of the bidirectional lead screw 502 are coaxially fixed.
[0028] By driving the two-way screw rod 502 to rotate through the second motor 505, the two moving blocks 503 slidably connected in the limit frame 501 are restricted to translational movement, and the two-way screw rod 502 can drive the two moving blocks 503 to approach each other, and the two folded top plates 504 gradually turn to a vertical state, and then the position of the desktop 3 will gradually rise. Because it is a screw rod connection, it can ensure that the state of the desktop 3 will not be arbitrarily changed by external forces.
[0029] like Figure 3 As shown, a plurality of rollers 406 are disposed at the bottom of the four extension plates 404, and the plurality of rollers 406 are in contact with the ground, so that the extension plates 404 encounter less resistance during movement, and the support column 2 of the desk is in contact with the ground, which can ensure that it will not move at will.
[0030] like Figure 2 As shown, the threads at both ends of the bidirectional screw 502 have the same parameters except for the opposite rotation directions, and the thread lead angles of the threads at both ends are smaller than the equivalent friction angle, so that it has a self-locking property.
[0031] The utility model provides a lifting and stable desk, and the specific working principle is as follows:
[0032] When the device is working, the two-way screw rod 502 is driven to rotate by the motor 2 505, and the two moving blocks 503 slidably connected to the limit frame 501 are restricted to translation, and the two-way screw rod 502 can drive the two moving blocks 503 to move closer to each other, and the two folded top plates 504 are gradually transformed to a vertical state, and then the position of the desktop 3 is gradually improved. Because it is a screw rod connection, it can ensure that the state of the desktop 3 will not be arbitrarily changed by external force, and then the motor 1 405 drives a screw rod 1 402 connected to it to rotate, and the sliding connection is in the installation slot. The extension plate 404 in one 401 is restricted to only translational movement, and the screw rod one 402 can drive the extension plate 404 to move toward the outside of the mounting slot two 403. The screw rod one 402 drives another screw rod one 402 to rotate through the connecting shaft 407, and the connecting shaft 407 also drives the pulley 408 outside it to rotate synchronously. This pulley 408 can drive another pulley 408 to rotate through the belt 409, so the other two screw rods 402 will also rotate synchronously, and then the other extension plates 404 will move outward at the same time, and the supporting area of the office desk will be greatly increased.
