Description

Technical Field

[0001] This invention belongs to the field of desk lamp manufacturing technology, and in particular relates to an eye-protecting desk lamp and its testing device. Background Technology

[0002] An "eye-protecting desk lamp" mainly consists of an adjustable stand, a lamp holder, and a lamp head. The lamp head is usually composed of a light source with good light quality, the lamp holder is a lampshade that can improve the uniformity of light distribution and reduce or lower glare, and a drive circuit that provides current to the light source.

[0003] Adjustable lamp holders typically include multiple connecting brackets, which are usually connected by a damping shaft to facilitate adjustment of the lamp head position during use. However, repeated friction during use may cause the damping shaft to lose its damping function, rendering the eye-protection desk lamp unusable. This results in a short lifespan for traditional eye-protection desk lamps. To address these issues, an eye-protection desk lamp and its testing device are provided.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide an eye-protecting desk lamp and its detection device. By fixing a first gear on a damping shaft and simultaneously providing a limiting component for limiting the first gear, the lamp can continue to be used even after the damping shaft loses its damping function, thus extending the lifespan of the eye-protecting desk lamp.

[0006] To achieve the above objectives, the present invention proposes an eye-protecting desk lamp, which includes a base and an adjustment bracket on the base.

[0007] The adjustment bracket includes a first U-shaped bracket fixed above the base, a first connecting rod rotatably mounted on the first U-shaped bracket, a second U-shaped bracket fixed at the end of the first connecting rod away from the first U-shaped bracket, and an L-shaped connecting rod rotatably mounted on the second U-shaped bracket.

[0008] Both the pivot of the first connecting rod and the pivot of the L-shaped connecting rod are damped pivots.

[0009] A first gear is fixed on the shaft of the first connecting rod and the shaft of the L-shaped connecting rod. A limiter is fixed on the first U-shaped bracket and the second U-shaped bracket. The limiter is used to limit the first gear.

[0010] Furthermore, the limiting member includes a first connecting piece, a second connecting piece and a third connecting piece that are vertically and parallelly distributed on the first connecting piece, the third connecting piece being fixed on a corresponding first U-shaped bracket or a second U-shaped bracket, the second connecting piece having a first sliding shaft that is parallel to the first connecting piece, the first sliding shaft having a threaded groove at one end near the third connecting piece, and a locking block corresponding to the first gear being fixed at the other end.

[0011] Furthermore, a drive button is rotatably provided on the third connecting piece, and a lead screw that mates with the threaded groove is fixed on the rotating shaft of the drive button.

[0012] Furthermore, a clamping piece corresponding to the third connecting piece is vertically fixed at one end of the first sliding shaft near the third connecting piece.

[0013] Furthermore, a lampshade is fixed on the adjusting bracket, a lamp holder is installed inside the lampshade, and the lampshade is fixed on the L-shaped connecting rod.

[0014] Furthermore, a brush strip is rotatably mounted on the L-shaped connecting rod.

[0015] Furthermore, the brush strip is arc-shaped, and its lower part is attached to the surface of the lampshade.

[0016] A testing device is applied to the aforementioned eye-protection desk lamp. The testing device is used to test the service life of two damping shafts on the eye-protection desk lamp. The testing device includes a testing component, which includes a fixing block. A connecting bracket is fixed on the fixing block. An electric telescopic rod is fixed on the connecting bracket. A connecting block is fixed on the output shaft of the electric telescopic rod. A motor is fixed on the connecting block. A second gear is fixed through the output shaft of the motor and through the connecting block.

[0017] Furthermore, a distance sensor is fixed to one side of the fixing block.

[0018] Furthermore, when using the aforementioned detection device to test the eye-protection desk lamp, the fixing block is clamped and fixed by the limiting component. After fixing, the second gear corresponds to the first gear.

[0019] The eye-protecting desk lamp and its detection device proposed in this invention can bring the following beneficial effects:

[0020] 1. The eye-protection desk lamp of the present invention can continue to be used even after the damping shaft loses its damping function by fixing the first gear on the damping shaft and setting a limiting component for limiting the first gear, thereby extending the service life of the eye-protection desk lamp.

[0021] 2. When the eye-protecting desk lamp of the present invention is in use, if the damping shaft does not lose its damping characteristics, the limiting part can be used as a fixing clip to make it easy to fix the eye-protecting desk lamp on a bookshelf or other fixed object, so as to prevent the eye-protecting desk lamp from being knocked to the ground.

[0022] 3. In use, the detection device of the present invention clamps and fixes the fixed block through the limiting member, and controls the second gear to mesh with the first gear. By starting the motor, the second gear is controlled to rotate, which in turn drives the corresponding first gear to rotate, which in turn drives the corresponding damping shaft to rotate, causing the corresponding first connecting rod or L-shaped connecting rod to swing back and forth. The retraction of the electric telescopic rod controls the second gear to disengage from the first gear. After disengagement, it is observed whether the data detected by the distance sensor has changed, and thus it is determined whether the damping shaft has lost its damping characteristics. Therefore, the detection device is not only simple in structure and easy to operate, but also flexible in use and can complete the detection of two damping shafts. Attached Figure Description

[0037] An embodiment of the present invention provides an eye-protecting desk lamp, which includes a base 1, such as... Figure 1As shown, the base 1 is provided with an adjustment bracket 2, the adjustment bracket 2 is fixed with a lampshade 3, and the lamp head 4 is installed inside the lampshade 3.

[0038] The adjustment bracket 2 includes a first U-shaped bracket 21 fixed above the base 1, such as... Figure 2 As shown, a first connecting rod 22 is rotatably mounted on the first U-shaped bracket 21, and a second U-shaped bracket 23 is fixed to the end of the first connecting rod 22 away from the first U-shaped bracket 21. An L-shaped connecting rod 24 is rotatably mounted on the second U-shaped bracket 23, and the lampshade 3 is fixed on the L-shaped connecting rod 24.

[0039] The pivot of the first connecting rod 22 and the pivot of the L-shaped connecting rod 24 are both damping pivots.

[0040] Both the pivot of the first connecting rod 22 and the pivot of the L-shaped connecting rod 24 are fixed with a first gear 25, such as... Figure 3 As shown, a limiting member 5 is fixed on both the first U-shaped bracket 21 and the second U-shaped bracket 23. The limiting member 5 is used to limit the first gear 25.

[0041] The limiting member 5 includes a first connecting piece 51, such as Figure 4 As shown, a second connecting piece 52 and a third connecting piece 53 are vertically and parallelly distributed on the first connecting piece 51. The third connecting piece 53 is fixed on the corresponding first U-shaped bracket 21 or second U-shaped bracket 23. A first sliding shaft 54 ​​parallel to the first connecting piece 51 is slidably provided on the second connecting piece 52. A threaded groove 56 is opened at one end of the first sliding shaft 54 ​​near the third connecting piece 53, and a locking block 55 corresponding to the first gear 25 is fixed at the other end.

[0042] The third connecting piece 53 is rotatably equipped with a drive button 57, and a lead screw 58 that mates with the threaded groove 56 is fixed on the rotating shaft of the drive button 57.

[0043] The first sliding shaft 54 ​​has a clamping piece 59 corresponding to the third connecting piece 53 vertically fixed at one end near the third connecting piece 53.

[0044] An arc-shaped brush strip 7 is rotatably mounted on the L-shaped connecting rod 24. The lower part of the brush strip 7 is attached to the surface of the lampshade 3. By rotating the brush strip 7, the dust on the surface of the lampshade 3 can be removed.

[0045] A testing device is applied to the aforementioned eye-protection desk lamp. The testing device is used to test the service life of two damping shafts on the eye-protection desk lamp. The testing device includes a testing component 6, such as... Figure 5As shown, the detection component 6 includes a fixing block 61, a connecting bracket 62 fixed on the fixing block 61, an electric telescopic rod 63 fixed on the connecting bracket 62, a connecting block 64 fixed on the output shaft of the electric telescopic rod 63, a motor 65 fixed on the connecting block 64, a second gear 66 fixed through the output shaft of the motor 65, and a distance sensor 67 fixed on one side of the fixing block 61. The distance sensor 67 is electrically connected to a preset control system.

[0046] When using this testing device to test eye-protection desk lamps, such as Figure 6 , Figure 7 As shown, the fixing block 61 is placed between the third connecting piece 53 and the clamping piece 59, and the distance sensor 67 is oriented towards the corresponding first connecting rod 22 or L-shaped connecting rod 24. The screw 58 is rotated by rotating the drive knob 57. With the cooperation of the threaded groove 56 and the screw 58, the third connecting piece 53 and the clamping piece 59 move closer to each other, thereby clamping and fixing the fixing block 61. After fixing, the second gear 66 corresponds to the first gear 25.

[0047] During testing, the second gear 66 can be engaged with the first gear 25 by extending the electric telescopic rod 63. The second gear 66 is rotated by starting the motor 65, which in turn drives the first gear 25 to rotate, which in turn drives the corresponding damping shaft to rotate. This causes the corresponding first connecting rod 22 or L-shaped connecting rod 24 to swing back and forth. After a preset number of swings (the more times the test is conducted, the fewer the preset number is set), the electric telescopic rod 63 is retracted to disengage the second gear 66 from the first gear 25. After disengagement, the data detected by the distance sensor 67 is observed to see if there is a change. If there is a change, it indicates that the corresponding first connecting rod 22 or L-shaped connecting rod 24 has rotated under the action of gravity, and the corresponding damping shaft has lost its damping characteristics and reached its service life. If the data detected by the distance sensor 67 does not change, it indicates that the damping shaft still maintains its damping characteristics. The above testing method is continued until the damping shaft loses its damping characteristics. The total number of swings is recorded to obtain the service life of the damping shaft.

[0048] When the eye-protecting desk lamp of the present invention is in use, if the damping shaft does not lose its damping characteristics, the locking block 55 will disengage from the corresponding first gear 25, thereby facilitating the adjustment of the eye-protecting desk lamp. At this time, the limiting member 5 can be used as a fixing clip to fix the eye-protecting desk lamp on a bookshelf or other fixed object, preventing the eye-protecting desk lamp from being knocked to the ground.

[0049] If the damping shaft loses its damping characteristics, after adjusting the adjustment bracket 2, the control block 55 is locked onto the first gear 25 by rotating the drive button 57, thereby limiting the adjustment bracket 2 and extending the service life of the eye-protection desk lamp.

[0050] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0051] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
