DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1

[0020] See also Figure 1-3A multi-directional adjustable eye protection desk lamp comprises a lamp holder 1, a plug wire 2 is arranged on the lamp holder 1, a rotating groove 3 is opened inside the lamp holder 1, a steering mechanism 4 is arranged inside the rotating groove 3, a suction cup 5 is fixedly connected to the outer wall of the bottom of the lamp holder 1, and the lamp holder 1 can be well fixed on a desktop or other plane through the arrangement of the suction cup 5, so as to prevent the desk lamp from being easily displaced during use. A limiting device 6 is arranged inside the lamp holder 1, and the steering mechanism 4 comprises a rotating rod 41, which is rotatably connected to the rotating groove 3, and a bevel gear 42 is fixedly connected to the outer wall of the rotating rod 41. The lamp holder 1 is rotatably and slidably connected with a control block 43, which passes through the inner wall of the lamp holder 1. A slideway in the shape of a circular groove connected with a plurality of transverse grooves is provided on the outer wall of the control block 43, and the connection between the circular groove and the transverse groove is set to an inclined fillet. By setting the shape of the slideway on the outer wall of the control block 43, it is ensured that when the control block 43 moves toward the inside of the lamp holder 1, the control block 43 can rotate, and when the control block 43 is pulled outward, the control block 43 cannot rotate, thereby preventing accidental touch. The end of the control block 43 close to the bevel gear 1 42 is fixedly connected with the bevel gear 2 44. A fixing ring 45 is rotatably connected to the outer wall of the control block 43, and the fixing ring 45 is slidably connected to the inner wall of the lamp holder 1. A mounting groove 46 is provided in the inner wall of the lamp holder 1, and a stopper 47 is fixedly connected to the inner wall of the mounting groove 46. A capsule 48 is arranged between the stopper 47 and the fixing ring 45. The whole material of the capsule 48 is soft rubber, and the inside of the capsule 48 is filled with a non-Newtonian fluid. By setting the material of the capsule 48, it is ensured that the capsule 48 has a certain deformation ability, and by setting the filling material inside the capsule 48, it is ensured that the capsule 48 can be deformed under the action of a relatively slow force. The capsule 48 is fixedly connected to the outer wall of the capsule 48 and the stopper 47, and the outer wall of the capsule 48 is fixedly connected to the fixing ring 45. The rotating rod 41 is fixedly connected to the lamp body 49. After the control block 43 is pushed in, the control block 43 is rotated, so that the rotating rod 41 is rotated under the joint action of the bevel gear 1 42 and the bevel gear 2 44, so as to achieve the effect of adjusting the steering. The fixing ring 45, the stopper 47 and the capsule 48 work together to ensure that when the control block 43 is subjected to a faster force, it cannot change its position, so as to achieve the effect of preventing accidental touch.

[0021] During use, when the user needs to adjust the rotation direction of the lamp body 49, the user first slowly pushes the control block 43 inwards. Since the capsule 48 is made of soft rubber and can be deformed, the capsule 48 can be deformed when the user slowly pushes the control block 43. At the same time, when the control block 43 is pushed until the annular groove on the outer wall contacts the inner wall of the lamp holder 1, the control block 43 can rotate, and at this time, the bevel gear 1 42 and the bevel gear 2 44 are just meshed. Therefore, at this time, the user rotates the control block 43, and the bevel gear 2 44 is driven to rotate by the control block 43, so that the rotating rod 41 rotates under the drive of the bevel gear 1 42, and the lamp body 49 rotates under the drive of the rotating rod 41. When the adjustment is completed, the user pulls the control block 43 outwards, so that the bevel gear 1 42 is driven to rotate. Gear 1 42 is separated from bevel gear 2 44. At the same time, under the pulling force of the user, the control block 43 makes the transverse groove on the outer wall of the control block 43 and the inner wall of the lamp holder 1 in the same plane. At this time, the control block 43 cannot rotate. At the same time, during the movement of the control block 43, the limit device 6 is driven so that the limit device 6 limits the rotating rod 41. When the user accidentally touches the control block 43 during use, the movement amplitude caused by the accidental touch is often large. Therefore, when the user touches the control block 43 at this time, the non-Newtonian fluid inside the capsule 48 is subjected to a large force and solidifies into a solid in an instant. Therefore, the user cannot push the control block 43, and the limit device 6 cannot release the limit, and the user will not accidentally change the direction of the desk lamp.

[0022] Embodiment 2

[0023] See also Figure 1-4On the basis of the first embodiment, the limiting device 6 includes a mounting ring 61, which is fixedly connected to the inner wall of the top of the lamp holder 1, and the mounting ring 61 is rotatably connected to a turntable 62, on which a control groove 63 is provided, and on which a moving groove 64 is provided, and the inner wall of the mounting ring 61 is slidably connected to a clamping strip 65, on which a protruding block is fixedly connected, and the protruding block passes through the inner wall of the turntable 62 through the control groove 63, and the protruding block is slidably connected to the control groove 63. By setting the protruding block, it is ensured that when the turntable 62 rotates, the protruding block can drive the position of the clamping strip 65 to move under the drive of the slide groove, so as to achieve the expected effect. A bayonet 66 is provided on the outer wall of the rotating rod 41, and the number of the clamping strips 65 is the same as the number of the clamping strips 65 provided on the control block 43. The number of transverse grooves is consistent, and when the transverse grooves are moved to the position where the control block 43 can be pulled outward, the card strip 65 is exactly matched with the position of the card slot 66. The consistent number and positional relationship between the transverse grooves and the card strip 65 ensure that when the staff pulls out the control block 43, the card strip 65 can always enter the card slot 66 to achieve the limiting effect on the rotating rod 41. A moving bar 67 is fixedly connected to the top of the fixed ring 45. The moving bar 67 is slidably connected to the inner wall of the moving groove 64. By pulling the control block 43 outward, the moving bar 67 drives the turntable 62 to rotate through the moving groove 64, thereby driving the card strip 65 to move through the control groove 63, so that the card strip 65 enters the card slot 66 to achieve the limiting effect on the rotating rod 41.

[0024] When in use, based on the first embodiment, when the user pulls the control block 43 outward, the moving bar 67 moves with the movement of the control block 43. Since the end of the control block 43 away from the control block 43 is arranged inside the moving groove 64, when the moving bar 67 moves, it can drive the turntable 62 to rotate. At this time, the position of the control groove 63 changes with the movement of the turntable 62. Since the card bar 65 cannot rotate, when the turntable 62 rotates, the card bar 65 moves with the rotation of the turntable 62, so that the card bar 65 enters the card slot 64. 6. At this time, the rotating rod 41 is limited by the card strip 65, so it can be ensured that the rotating rod 41 cannot rotate. When the user pushes the control block 43 in the box, the control block 43 drives the moving bar 67 to move during the movement, thereby driving the rotating disk 62 to rotate through the moving groove 64, so that the rotating disk 62 drives the card strip 65 to move in the direction away from the rotating rod 41 under the drive of the control groove 63 during the rotation, thereby leaving the card slot 66. At this time, the rotating rod 41 is not limited by the card strip 65, so the rotating rod 41 can rotate normally under the action of the steering mechanism 4.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
