[0002] In the modern fast-paced life and working environment, portable mobile table lamps, as convenient and flexible lighting tools, are widely used in various scenarios such as reading, studying, working, and outdoor adventures. However, traditional portable mobile table lamps often adopt a fixed lamp head design, and their illumination range is relatively fixed, making it difficult to meet the diverse needs of users for the illumination area and brightness in different scenarios. For example, when reading, a smaller focused light spot may be required to reduce eye fatigue, while when working on a workbench, a wider and more uniform light coverage may be needed.

[0003] Chinese Patent Publication No. CN113864679A discloses a portable table lamp with adjustable light size. By the user moving the connecting ring to the right, the blocking block can be driven to move inward to block part of the light of the electric lamp head, and the light can be adjusted smaller, which is more convenient to use. At the same time, the iron block is adsorbed by the magnet, which can prevent the connecting ring from resetting, and there is no need to manually press the blocking block, which is more labor-saving.

[0004] However, in actual use of the above structure, since its magnetic attraction fixation can only fix the blocking block at the expansion angle when in contact, the blocking angle and expansion angle of the blocking block are fixed, which is not convenient for fine positioning adjustment of the irradiation range of the lamp tube.

Detailed Implementation Modes

[0028] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the following will provide a more detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0029] Refer to Figures 1-3 As shown, a portable mobile table lamp that changes the illumination range based on rotation includes a table lamp main body 1, a lampshade 2 provided on the table lamp main body 1, and an adjustable shielding mechanism 3 slidably arranged vertically on the lampshade 2 for adjusting the illumination range. The adjustable shielding mechanism 3 includes a shielding plate 31 and a driving and locking mechanism 4 for driving a pair of shielding plates 31 to move relatively closer and farther away from each other. The portable mobile table lamp that changes the illumination range based on rotation further includes a dust-proof mechanism 5 provided on the lampshade 2 for shielding and protecting the table lamp main body 1.

[0030] When it is necessary to adjust the illumination range of the table lamp main body 1, first, the driving and locking mechanism 4 is set to drive a pair of shielding plates 31 to move relatively closer, thereby achieving the adjustment of the illumination range of the table lamp main body 1. At this time, the illumination range of the table lamp main body 1 is in a reduced state. When the pair of shielding plates 31 are moving away from each other, the illumination range of the table lamp main body 1 is in an expanded state. And after adjusting the position of the shielding plate 31, the position of the shielding plate 31 can be fixed by the driving and locking mechanism 4 to prevent the shielding plate 31 from freely sliding in the vertical direction, and fine adjustment and fixation of the adjusted shielding plate 31 can be performed.

[0031] Refer to Figures 3-4 As shown, the driving and locking mechanism 4 includes a circular travel groove 41, a rotating disk 42, and an arc groove 43. The circular travel groove 41 is opened on the lampshade 2. The rotating disk 42 is rotatably arranged in the circular travel groove 41. The arc groove 43 is opened on the rotating disk 42, and the arc groove 43 is used to limit the rotation and sliding of the shielding plate 31.

[0032] When it is necessary to drive a pair of shielding plates 31 to move relatively closer to change the irradiation range of the table lamp main body 1, first, the rotating disk 42 rotates. During this process, the rotating disk 42 can be driven to stably rotate along the circular travel groove 41 opened in the lampshade 2. And during the rotation of the rotating disk 42, the shielding plate 31 can be driven to slide through the arc groove 43 until a pair of shielding plates 31 move relatively closer, so that when the shielding plate 31 moves relatively closer, the user can stably slide the shielding plate 31 along the arc groove 43 through the rotating disk 42.

[0033] Refer to Figure 4As shown, the driving and locking mechanism 4 further includes a first linear limiting groove 44 and a first sliding block 45; the first linear limiting groove 44 is formed on the lamp cover 2 and there are a pair of them; the first sliding blocks 45 are respectively slidably arranged in the first linear limiting groove 44 and the arc groove 43, and the first sliding blocks 45 are fixedly connected to the shielding plate 31.

[0034] When the shielding plate 31 slides along the arc groove 43, during this process, the first sliding block 45 can be affected by the first linear limiting groove 44 at the same time and slide in the vertical direction, so as to adjust the irradiation range of the table lamp body 1.

[0035] See Figures 3-7 As shown, the driving and locking mechanism 4 further includes a connecting block 46, a stroke block 47, a sliding groove 48, a second sliding block 49, a clamping rod 491 and a first clamping groove 492; the connecting block 46 is arranged on the rotating disc 42; the stroke block 47 is arranged on the table lamp body 1; the sliding groove 48 is formed on the stroke block 47 and is used to limit the sliding of the connecting block 46; the second sliding block 49 is slidably arranged on the stroke block 47; the clamping rod 491 is slidably arranged in the vertical direction on the second sliding block 49; the first clamping groove 492 is arranged on the connecting block 46.

[0036] When the position of the shielding plate 31 needs to be adjusted, in the initial state, the clamping rod 491 moves downward in the vertical direction, and the clamping rod 491 is inserted into the first clamping groove 492. First, pull the clamping rod 491 upward in the vertical direction, so as to drive the clamping rod 491 away from the first clamping groove 492. Then, the connecting block 46 can slide in the sliding groove formed in the stroke block 47. Since the connecting block 46 is fixedly connected to the rotating disc 42, this enables the rotating disc 42 and the connecting seat to rotate along the stroke block 47. When the connecting block 46 slides, it can drive the second sliding block 49 to perform synchronous rotational tilting movement through the clamping rod 491. When fixing the rotated and tilted connecting block 46 and the second sliding block 49, loosening the vertical pulling force on the clamping rod 491 can drive the clamping rod 491 to engage with the first clamping groove 492, and then the connecting block 46 can be clamped and fixed.

[0037] See Figure 7 and Figure 8 As shown, the driving and locking mechanism 4 further includes a return spring 493 and a second clamping groove 494; the return spring 493 is arranged on the clamping rod 491, and both ends of the return spring 493 are fixedly connected to the second sliding block 49 and the end of the clamping rod 491 respectively; the second clamping groove 494 is formed on the stroke block 47.

[0038] When the clamping rod 491 is pulled vertically upward, the reset spring 493 is compressed at this time, and the clamping rod 491 slides out of the outer sides of the first clamping groove 492 and the second clamping groove 494. At this time, the clamping rod 491 loses the position fixation of the second sliding block 49 and the connecting block 46. When the clamping rod 491 is released, the reset spring 493 is released, driving the clamping rod 491 to be inserted into the first clamping groove 492 formed on the connecting block 46 and the second clamping groove 494 formed on the travel block 47 again, achieving the fixation after the position adjustment of the shielding plate 31 and preventing it from sliding freely.

[0039] See Figure 3 As shown, the dust-proof mechanism 5 includes a damping rod 51, a dust-proof plate 52 and a storage block 53; the damping rod 51 is arranged on the lamp shade 2 and above the shielding plate 31; the dust-proof plate 52 is rotatably arranged on the damping rod 51 and used to shield the lamp body 1; the storage block 53 is arranged on the lamp shade 2 and used to store and fix the dust-proof plate 52. A flexible extrusion block 531 is arranged in the storage block 53, and the flexible extrusion block 531 can extrude the dust-proof plate 52 into the storage block 53, reducing the possibility of its free rotation.

[0040] When it is necessary to shield and protect the lamp body 1 and the lamp shade 2, first rotate the dust-proof plate 52 along the damping rod 51 until the dust-proof plate 52 disengages from the outside of the storage block 53. The setting of the damping rod 51 can increase the contact force between the dust-proof plate 52 and the damping rod 51, reduce the free rotation of the dust-proof plate 52, achieve the shielding and protection of the lamp body 1 and the lamp shade 2, reduce the adhesion of dust, etc., and indirectly improve the service life of the lamp body 1 and the lamp shade 2.

[0041] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
