[0024] like Figure 1-Figure 5 As shown, the hand-cranked power generation structure work lamp provided in this embodiment includes a lamp frame housing 1, one end of the lamp frame housing 1 is damped and hinged with a connecting base 2, the connecting base 2 includes a hinge block 3, a damping shaft 4 arranged on the inner side of the hinge block 3 and a lamp holder 20 arranged on the damping shaft 4, the damping shaft 4 includes a first sleeve 5 arranged on the hinge block 3 and a second sleeve 6 rotatably embedded in the end of the first sleeve 5, the lamp frame housing 1 is provided with a manual crank 7 on the upper surface of one end away from the hinge of the connecting base 2, the lamp frame housing 1 is convenient for supporting and storing the connecting base 2, The connecting base 2 is convenient for supporting the first working light 11 and the second working light 12. The connecting base 2 is convenient for hingedly connecting the connecting base 2 to the lamp holder shell 1. The damping shaft 4 is convenient for rotating the lamp holder 20 in another direction. At the same time, the lamp holder 20 can be rotatably connected to the connecting base 2. The lamp holder 20 is convenient for fixing the first working light 11 and the second working light 12. The first sleeve 5 is convenient for connecting one end of the damping shaft 4 to the hinge block 3. The second sleeve 6 is convenient for connecting the other end of the damping shaft 4 to the lamp holder 20. The manual crank 7 facilitates the device to generate electricity by hand.

[0025] The first sleeve 5 is fixed to the side of the hinge block 3 close to the damping shaft 4 by the first bolt 8, and the second sleeve 6 is fixed to the side of the lamp holder 20 close to the damping shaft 4 by the first bolt 8. The first bolt 8 facilitates the fixed connection between the first sleeve 5 on the damping shaft 4 and the hinge block 3, and the first bolt 8 also facilitates the fixed connection between the second sleeve 6 on the damping shaft 4 and the lamp holder 20, so that the hinge block 3 and the lamp holder 20 can be connected together in damped rotation under the action of the damping shaft 4.

[0026] The first sleeve 5 and the second sleeve 6 are both configured to be frosted to increase the damping effect of the first sleeve 5 and the second sleeve 6 engagement contact surface. A protective shell 22 is sleeved on the damping shaft 4 to provide physical protection for the damping shaft 4.

[0027] The protective shell 22 includes an upper shell 21 and a lower shell 9 embedded in the upper shell 21. The upper shell 21 and the lower shell 9 are fixed to the hinge block 3 by a second bolt 10. The shell 21 and the lower shell 9 are engaged with each other to wrap the damping shaft 4 therein, thereby playing a role of physical protection. The second bolt 10 facilitates fixing the shell 21 and the lower shell 9 that are locked together to the hinge block 3.

[0028] The lamp holder 20 is provided with a first working light 11 on the same side as the manual crank 7, and the lamp holder 20 is provided with a second working light 12 on the side away from the damping shaft 4. The first working light 11 is convenient for illuminating a larger space, and the second working light 12 is convenient for illuminating a narrow gap.

[0029] The manual crank 7 includes a rotating shaft 13 rotatably mounted on the lamp holder housing 1, a connecting plate 14 arranged on the rotating shaft 13, and a turning handle 15 rotatably mounted on the connecting plate 14. The rotating shaft 13 allows the manual crank 7 to rotate on the lamp holder housing 1. The connecting plate 14 facilitates connecting the rotating shaft 13 with the turning handle 15, and the turning handle 15 facilitates manual rotation of the manual crank 7.

[0030] A placement base 16 is provided at one end of the lamp holder housing 1 away from the hinge of the connection base 2, and a charging port 17 is provided on the placement base 16. The placement base 16 is convenient for placing the device vertically somewhere when not in use to reduce the placement area. The charging port 17 is convenient for the device to be not limited to hand-cranked power generation, but also to be directly charged.

[0031] An annular magnetic strip 18 is provided at the outer edge of the base 16, and an anti-skid groove 19 is opened on the turning handle 15. The annular magnetic strip 18 can adsorb the device in an appropriate position, and there is no need to hold it when working conditions permit. The anti-skid groove 19 is convenient for increasing the friction of the turning handle 15 so that the turning handle 15 will not fall out of the hand when it is used to generate electricity by hand.

[0032] like Figure 1-Figure 5 As shown, the principle of the hand-cranked power generation structure work lamp provided in this embodiment is as follows: when using and installing the device, the wire used to connect the first work lamp 11 and the second work lamp 12 should be passed through the damping shaft 4, and then the first sleeve 5 in the damping shaft 4 is tightened and fixed to the hinge block 3 by the first bolt 8, and then the second sleeve 6 in the damping shaft 4 is tightened and fixed to the lamp holder 20 by the first bolt 8, and then the upper shell 21 and the lower shell 9 are clamped together, and then the lamp holder 20 is rotated so that the side of the upper shell 21 and the lower shell 9 that are in contact with the lamp holder 20 is exposed as much as possible, and then the clamped upper shell 21 and the lower shell 9 are fixed to the hinge block 3 by the second bolt 10;

[0033] When in use, the lamp holder 20 can be flipped out of the lamp holder shell 1 through the hinge block 3, and then the user can judge whether to turn on the first working light 11 or the second working light 12 according to the environment of the place where the user is using it, and then fine-tune the rotation of the lamp holder 20 according to the required lighting angle during use. At this time, the lamp holder 20 will be rotated to the required angle and fixed under the action of the damping shaft 4. If it is found that the light is weak or there is no power during use, you can first check around to see if there is a charger. If there is, you can charge the device through the charging port 17. If not, you can charge the device by manually cranking the hand crank 7. After use, you can fine-tune the lamp holder 20 to the initial position through the damping shaft 4, and then flip the lamp holder 20 through the hinge block 3 to store it in the lamp holder shell 1.

[0034] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0035] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0036] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
