DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figures 1 to 10 The present invention provides an intelligent desk, and the technical solution is as follows:

[0033] A smart office desk comprises a fixed frame 1 and a fixed seat 25, a mobile frame 24 is slidably mounted on the fixed seat 25, the fixed frame 1 is fixedly mounted on the mobile frame 24, two rotating plates 2 are symmetrically rotatably mounted on the outer walls on both sides of the fixed frame 1, a workbench 3 is fixedly mounted on the two rotating plates 2, two displays 4 are symmetrically fixedly mounted in the fixed frame 1, a driving box 5 is fixedly mounted on the top of the fixed frame 1, a motor 6 is fixedly mounted on the top wall of the driving box 5, an output shaft 13 is rotatably mounted on the bottom end of the motor 6, a reciprocating screw 8 is rotatably mounted in the fixed frame 1, a first threaded tube 7 is threadedly mounted on the reciprocating screw 8, two cleaning frames 9 are symmetrically fixedly mounted on the first threaded tube 7, a right-angle slide bar 10 is fixedly mounted on the two cleaning frames 9 at one end away from each other, and two slide grooves 11 matching the right-angle slide bar 10 are symmetrically opened on the fixed frame 1.

[0034] The motor 6 drives the output shaft 13 to rotate, and the output shaft 13 drives the reciprocating screw 8 to rotate. The reciprocating screw 8 rotates while the first threaded tube 7 does not rotate, so that the first threaded tube 7 moves back and forth on the reciprocating screw 8, thereby driving the two cleaning racks 9 to move up and down, so that the cleaning racks 9 can be used to clean the two displays 4, thereby extending the service life of the equipment and improving the quality of use of the office desk.

[0035] As an embodiment of the present invention, refer to Figure 6 A first limit block 12 is fixedly installed on the top end of the reciprocating screw 8, a first spring rod 14 is fixedly installed on the bottom end of the output shaft 13, a first clamping block 15 is fixedly installed on the bottom end of the first spring rod 14, a clamping slot matching the first clamping block 15 is opened at the top end of the first limit block 12, and an electromagnet is arranged in the clamping slot.

[0036] Under normal circumstances, the electromagnet on the first limit block 12 is in an energized state, that is, the first clamping block 15 is normally located in the clamping slot, so that the output shaft 13 can drive the first limit block 12 to rotate, and the first limit block 12 drives the reciprocating screw 8 to rotate. The purpose of a single motor 6 driving multiple components is achieved by flexible disconnection, thereby reducing the production cost of the equipment.

[0037] As an embodiment of the present invention, refer to Fig.10 A trigger box 44 is fixedly mounted on the outer wall of one side of the fixing frame 1, two contact electrodes 45 are symmetrically and movably mounted in the trigger box 44, a movable plate 46 is movably mounted in the trigger box 44, a circuit breaker plate 50 is fixedly mounted on the upper outer wall of the movable plate 46, a hemispherical block 49 is fixedly mounted on the bottom wall of the movable plate 46, two mounting plates 47 are symmetrically and movably mounted on the inner walls on both sides of the trigger box 44, and circuit breaker springs 48 are respectively connected between the two mounting plates 47 and the movable plate 46.

[0038] When the workbench 3 is folded up, the end of the rotating plate 2 no longer presses against the hemispherical block 49, and the hemispherical block 49 moves downward under the elastic force of the circuit-breaking spring 48, thereby causing the circuit-breaking plate 50 to move downward. The two contact electrodes 45 lose the separation of the circuit-breaking plate 50 and reconnect with each other, so that the circuit is connected, and the motor 6 starts to drive the reciprocating screw 8 to rotate, thereby completing the cleaning work and achieving the effect of automatic cleaning after the workbench 3 is folded up, thereby improving the quality of cleaning. It is worth noting that the connection between the two contact electrodes 45 and the trigger box 44 is an elastic connection, thereby realizing the disconnection and recovery of the circuit.

[0039] As an embodiment of the present invention, refer to Figure 6 and Figure 8Two transmission rods 19 are symmetrically rotatably installed on the top wall of the fixed frame 1, and a first belt pulley 23 is fixedly installed on the two transmission rods 19. A fixing plate 26 is fixedly installed on the back of the fixed frame 1. Two second threaded tubes 28 matching the threaded rods 27 are fixedly inserted on the fixing seat 25. The tops of the two threaded rods 27 are fixedly installed with second belt pulleys 29. A transmission tube is movably sleeved on the outer edge of the lower end of the second belt pulley 29. The lower end of the transmission tube is rotatably connected to the fixed plate 26, and a transmission belt is connected between the first belt pulley 23 and the second belt pulley 29.

[0040] The two threaded rods 27 are driven to rotate by belt transmission. The threaded rods 27 rotate, while the second threaded tube 28 does not rotate and is fixed in position, so that the threaded rods 27 move up and down while rotating. When the threaded rods 27 move up and down, the second belt pulley 29 fixed thereto drives the fixed plate 26 to move up and down through the transmission tube, thereby driving the fixed frame 1 and the movable frame 24 to slide up and down on the fixed seat 25, so as to realize the height adjustment of the fixed frame 1, and further improve the use quality of the office desk.

[0041] As an embodiment of the present invention, refer to Figure 6 Two rotating rods 16 are symmetrically rotatably installed on the inner top wall of the driving box 5, and the bottom ends of the two rotating rods 16 are fixedly installed with second spring rods 17, and the bottom ends of the two second spring rods 17 are fixedly installed with second clamping blocks 18. The top ends of the two transmission rods 19 are fixedly installed with second limit blocks 20, and the top walls of the two second limit blocks 20 are provided with clamping grooves matching the second clamping blocks 18, and electromagnets are provided in the clamping grooves. A first gear 21 is fixedly installed on the output shaft 13, and a second gear 22 meshing with the first gear 21 is fixedly installed on the two rotating rods 16.

[0042] Under normal circumstances, the first card block 15 is stuck in the slot on the first limit block 12, and the two second card blocks 18 are not in the slot of the second limit block 20, which means that the electromagnet on the second limit block 20 is normally in a power-off state. It is worth noting that the first card block 15 and the second card block 18 are both stepped, and the fixing frame 1 is provided with an upper and lower switch. Pressing the switch can cut off the power to the electromagnet in the first limit block 12 and energize the electromagnet in the slot of the second limit block 20. The two second card blocks 18 are stuck into the slot on the second limit block 20 under the action of the magnetic force of the electromagnet, which means that the two rotating rods 16 can drive the two transmission rods 19 to rotate. The two rotating rods 16 rotate with the output shaft 13 through gear transmission, so that a single motor 6 can complete the cleaning and lifting work, and the two do not interfere with each other, which improves the use quality of the office desk and reduces the production cost.

[0043] As an embodiment of the present invention, refer to Figure 8 and Fig. 9A socket is provided on the cleaning frame 9, in which a sliding plate 32 is slidably installed. Two first transposition plates 30 are symmetrically fixedly installed on the inner top wall of the fixed frame 1, and two second transposition plates 31 are symmetrically fixedly installed on the inner bottom wall of the fixed frame 1. Two insertion rods 51 are symmetrically and movably inserted on the cleaning frame 9, and a first sponge 33 and a second sponge 34 are fixedly installed on the two insertion rods 51, respectively. Two water tanks 52 are symmetrically fixedly installed on the top of the fixed frame 1, and multiple piston cylinders 36 are fixedly installed on the outer walls of the two water tanks 52. A liquid inlet pipe 40 is connected between the piston cylinder 36 and the water tank 52. A plurality of nozzles 43 are provided in the fixed frame 1, and a liquid outlet pipe 41 is connected between the multiple piston cylinders 36 and the multiple nozzles 43.

[0044] When the cleaning rack 9 reaches the top position, the first transposition plate 30 is inserted into the insertion hole, pushing the sliding plate 32 to move downward, so that the second sponge 34 is pushed out and moves in the direction away from the cleaning rack 9. During the descent of the cleaning rack 9, after the first transposition plate 30 leaves the insertion hole, the first sponge 33 loses the pressure and moves closer to the cleaning rack 9. On the contrary, when the cleaning rack 9 descends to the bottom, the second transposition plate 31 uses the same method to move the first sponge 33 away from the cleaning rack 9, while the second sponge 34 approaches the cleaning rack 9. In this way, during the cleaning process, the first sponge 33 and the second sponge 34 are used for alternating cleaning, and then the piston cylinder 36 sprays the cleaning liquid in the water tank 52 onto the second sponge 34, thereby improving the cleaning quality and thus improving the use quality of the office desk.

[0045] As an embodiment of the present invention, refer to Figure 4 One-way valves are respectively provided on the liquid inlet pipe 40 and the liquid outlet pipe 41.

[0046] The one-way valves on the liquid inlet pipe 40 and the liquid outlet pipe 41 are used for one-way liquid inlet and one-way liquid outlet, so as to further improve the cleaning effect.

[0047] As an embodiment of the present invention, refer to Figure 1 An upper push plate 42 is fixedly installed on each of the two right-angle slide bars 10 , a piston rod 37 is movably inserted at the bottom end of each of the piston cylinders 36 , a return spring 38 is sleeved on each of the piston rods 37 , and a connecting plate 39 is fixedly installed at the bottom ends of the multiple piston rods 37 .

[0048] When the cleaning rack 9 rises to the highest point, the right-angle slide bar 10 is used to drive the two upper push plates 42 to push the two connecting plates 39, so that the cleaning liquid in the piston cylinder 36 is pressed out, and is sprayed out by the nozzle 43 and sprayed on the second sponge 34. When the upper push plate 42 moves downward, the return spring 38 helps the connecting plate 39 to move downward, so that the piston rod 37 descends, and the cleaning liquid in the water tank 52 is sucked into the piston cylinder 36 by the liquid inlet pipe 40 to complete the feeding. In this way, the first sponge 33 is wiped dry and the second sponge 34 is cleaned, which further improves the cleaning effect.

[0049] As an embodiment of the present invention, refer to Fig. 9 A third spring rod 35 is connected between the first sponge 33 and the second sponge 34 and the cleaning frame 9 respectively.

[0050] By setting the first spring rod 95, the first sponge 33 and the second sponge 34 can reciprocate promptly and effectively when they are squeezed by the first transposition plate 30, the second transposition plate 31 and the sliding plate 32, and when the above-mentioned squeezing fails, thereby ensuring the cleaning effect of the display 4.

[0051] As an embodiment of the present invention, refer to Figure 3 The bottom side of the fixing frame 1 is in a slope shape.

[0052] The inclined surface at the bottom of the fixing frame 1 is designed to prevent the workbench 3 from rubbing against the corners of the fixing frame 1 when the workbench 3 is rotated and retracted, thereby extending the service life of the equipment.

[0053] Working principle: the motor 6 drives the output shaft 13 to rotate, and the output shaft 13 drives the reciprocating screw 8 to rotate. The reciprocating screw 8 rotates while the first threaded tube 7 does not rotate, so that the first threaded tube 7 moves back and forth on the reciprocating screw 8, thereby driving the two cleaning racks 9 to move up and down, so that the cleaning racks 9 can be used to clean the two displays 4, thereby extending the service life of the equipment and improving the quality of use of the office desk.

[0054] When the workbench 3 is folded up, the end of the rotating plate 2 no longer presses against the hemispherical block 49, and the hemispherical block 49 moves downward under the elastic force of the circuit-breaking spring 48, thereby causing the circuit-breaking plate 50 to move downward. The two contact electrodes 45 lose the separation of the circuit-breaking plate 50 and reconnect with each other, so that the circuit is connected, and the motor 6 starts to drive the reciprocating screw 8 to rotate, thereby completing the cleaning work and achieving the effect of automatic cleaning after the workbench 3 is folded up, thereby improving the quality of cleaning. It is worth noting that the connection between the two contact electrodes 45 and the trigger box 44 is an elastic connection, thereby realizing the disconnection and recovery of the circuit.

[0055] The two threaded rods 27 are driven to rotate by belt transmission. The threaded rods 27 rotate, while the second threaded tubes 28 do not rotate and are fixed in position, so that the threaded rods 27 move up and down while rotating, thereby driving the fixed frame 1 and the movable frame 24 to slide up and down on the fixed seat 25, so as to achieve height adjustment of the fixed frame 1, further improving the use quality of the office desk.

[0056] Under normal circumstances, the electromagnet on the first limit block 12 is in an energized state, that is, the first clamping block 15 is normally located in the clamping slot, so that the output shaft 13 can drive the first limit block 12 to rotate, and the first limit block 12 drives the reciprocating screw 8 to rotate. The purpose of a single motor 6 driving multiple components is achieved by a flexible disconnection method, thereby reducing the production cost of the equipment. Under normal circumstances, the first clamping block 15 is stuck in the clamping slot on the first limit block 12, and the two second clamping blocks 18 are not in the clamping slot of the second limit block 20, which means that the electromagnet on the second limit block 20 is normally in a power-off state. It is worth noting that an upper and lower switch is provided on the fixed frame 1. Pressing the switch can cut off the power to the electromagnet in the first limit block 12, and energize the electromagnet in the second limit block 20, which means that the two rotating rods 16 can drive the two transmission rods 19 to rotate. The two rotating rods 16 rotate with the output shaft 13 through gear transmission, realizing that a single motor 6 completes the cleaning and lifting work, and the two do not interfere with each other, improving the use quality of the office desk and reducing the production cost.

[0057] When the cleaning rack 9 reaches the top position, the first transposition plate 30 is inserted into the insertion hole, pushing the sliding plate 32 to move downward, so that the second sponge 34 is pushed out and moves in the direction away from the cleaning rack 9. During the descent of the cleaning rack 9, after the first transposition plate 30 leaves the insertion hole, the first sponge 33 loses the pressure and moves closer to the cleaning rack 9. On the contrary, when the cleaning rack 9 descends to the bottom, the second transposition plate 31 uses the same method to move the first sponge 33 away from the cleaning rack 9, while the second sponge 34 approaches the cleaning rack 9, so that during the cleaning process, the first sponge 33 and the second sponge 34 are used for alternating cleaning, and then the piston cylinder 36 moves the water tank The cleaning liquid in 52 is sprayed onto the second sponge 34, which improves the cleaning quality and thus improves the use quality of the office desk. When the cleaning frame 9 rises to the highest point, the right-angle slide bar 10 is used to drive the two upper push plates 42 to push the two connecting plates 39, so that the cleaning liquid in the piston cylinder 36 is pressed out, and is sprayed out by the nozzle 43 and sprayed on the second sponge 34. When the upper push plate 42 moves downward, the return spring 38 helps the connecting plate 39 to move downward, so that the piston rod 37 descends, and the cleaning liquid in the water tank 52 is sucked into the piston cylinder 36 by the liquid inlet pipe 40 to complete the feeding. In this way, the first sponge 33 is wiped dry and the second sponge 34 is cleaned, which further improves the cleaning effect.
