DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] like Figure 1-Figure 8 As shown, a multifunctional safety helmet with low-voltage electric lighting for underground construction includes a safety helmet body and a strap 102. The safety helmet body is provided with a lighting assembly, a winding assembly and an adjustment assembly. The lighting assembly includes a battery 105, a cable tube 118 and an LED lamp 103. The battery 105 is fixedly connected to the safety helmet body, and the cable tube 118 is wound up by the winding assembly to control the distance between the LED lamp 103 and the safety helmet body. The lighting angle of the LED lamp 103 is controlled by the adjustment assembly.
[0028] The wires are wrapped in the cable tube 118, and the current is supplied from the battery 105 to the LED lamp 103 through the wires in the cable tube 118; when the personnel do not need to hold the LED lamp 103 during the operation, the winding assembly retracts the LED lamp 103 onto the helmet body, and the irradiation position of the LED lamp 103 changes synchronously with the personnel's head; when the operation requires, the personnel pull out the LED lamp 103 and can control the irradiation position of the LED lamp 103 at will. After completing this part of the operation, the LED lamp 103 can be retracted onto the helmet body using the winding assembly. The above arrangement solves the cumbersome operation problem of the prior art that personnel need to frequently insert the LED lamp 103 on the helmet body, and achieves the technical effect of taking it as needed and simplifying the operation; at the same time, the lighting assembly and the adjustment assembly are connected to the helmet body through the cable tube 118 to prevent the LED lamp 103 from being lost.
[0029] Embodiment 2:
[0030] like Figure 3-Figure 5 As shown, the winding assembly includes a winding shell 106 , to which a coil spring 107 is fixedly connected, and the coil spring 107 is fixedly connected to the battery 105 .
[0031] The cable tube 118 is wound around the reel shell 106. When a person pulls the cable tube 118, the coil spring 107 is deformed by force, and the reel shell 106 starts to rotate to release the cable tube 118. When a person releases the LED lamp 103, under the force of the coil spring 107, the reel shell 106 starts to reverse and retract the cable tube 118, thereby rewinding the cable tube 118. The above arrangement makes it easy to take and put the LED lamp 103. The LED lamp 103 can be automatically reset without the need for a person to insert the LED lamp 103 back to its original position.
[0032] like Figure 3-Figure 5 As shown, the helmet body includes an outer shell 101 and an inner shell 104, the outer shell 101 is fixedly connected to the inner shell 104, an interlayer is arranged between the outer shell 101 and the inner shell 104, and the winding shell 106 and the battery 105 are arranged in the interlayer.
[0033] The outer shell 101 and the inner shell 104 are both made of carbon fiber material. By setting up an interlayer, the heat of the outer shell 101 after being exposed to the sun will not be directly transferred to the inner shell 104, which will reduce the heat of the inner shell 104 and improve wearing comfort. At the same time, placing the battery 105 and the winding shell 106 in the interlayer can improve the aesthetics.
[0034] like Figure 3 As shown, the winding shell 106 is provided with a threaded receiving groove for accommodating the cable tube 118. By providing the threaded receiving groove, the cable tube 118 can be evenly distributed on the winding shell 106 to prevent the cable tube 118 from being disorderly during winding.
[0035] like Figure 6-Figure 7 As shown, the winding assembly includes a limit seat 108, the limit seat 108 is fixedly connected to the helmet body, the limit seat 108 is slidably connected to the retraction rod 109, the retraction rod 109 is fixedly connected to the spring 116, the spring 116 is fixedly connected to the limit seat 108, the retraction rod 109 is rotatably connected to the pressure block 117, the cable tube 118 passes through the limit seat 108, and the pressure block 117 cooperates with the cable tube 118.
[0036] When the personnel pull out the LED lamp 103, the inclined pressing block 117 will not get stuck on the cable tube 118. However, when the personnel release the LED lamp 103, although the cable tube 118 will be recovered under the action of the coil spring 107, the chamfer 110 remains stationary under the action of the spring 116, that is, the pressing block 117 cannot go up, so it will press the cable tube 118, resulting in the cable tube 118 being unable to be recovered. When the personnel manually lifts the retraction rod 109, the spring 116 is compressed, and the retraction rod 109 lifts the pressing block 117 upward. At this time, the pressing block 117 cannot press the cable tube 118, and the cable tube 118 can be retracted under the action of the coil spring 107. Through the above arrangement, it can be ensured that the LED lamp 103 will not retract when the personnel releases the LED lamp 103, avoiding the problem that the personnel need to manually use the LED lamp 103 again in a short period of time and need to frequently pull out the LED lamp 103.
[0037] like Figure 6-Figure 7 As shown, the adjustment assembly includes an adjustment seat 115, the limit seat 108 cooperates with the adjustment seat 115, and the adjustment seat 115 is fixedly connected to the cable tube 118. The cable tube 118 is retracted, so that the adjustment seat 115 is retracted into the limit seat 108, and the limit seat 108 is used to limit the adjustment seat 115. Through the above arrangement, when the LED lamp 103 is used on the helmet body, the LED lamp 103 can be stable and will not shake.
[0038] like Figure 6-Figure 8 As shown, the adjustment assembly includes a second adjustment rod 113, the second adjustment rod 113 is longitudinally rotationally connected to the adjustment seat 115, the second adjustment rod 113 is transversely rotationally connected to the first adjustment rod 111, the LED lamp 103 is fixedly connected to the first adjustment rod 111, the second adjustment rod 113 is fixedly connected to the second knob 114, and the first adjustment rod 111 is fixedly connected to the first knob 112.
[0039] There is a rotation resistance between the first adjustment rod 111 and the second adjustment rod 113 and between the second adjustment rod 113 and the adjustment seat 115. When a person turns the second knob 114 or the first knob 112, the rotation resistance can be overcome to adjust the irradiation position of the LED lamp 103; when the person does not operate the first knob 112 or the second knob 114, the position of the LED lamp 103 is maintained by the rotation resistance. The rotation resistance can be adjusted by setting a rubber gasket between the two. This setting is adaptively adjusted by those skilled in the art and will not be repeated again. Through the above setting, it is convenient for personnel to adjust the irradiation angle of the LED lamp 103 according to specific circumstances to adapt to different work scenes.
[0040] like Figure 7As shown, a chamfer 110 is provided on one end of the limit seat 108 away from the retracting rod 109. By providing the chamfer 110, a guiding effect can be provided when the adjustment seat 115 is retracted to the limit seat 108, preventing the adjustment seat 115 from failing to enter the limit seat 108.
[0041] Working principle: after putting on the helmet body, the personnel use the strap 102 to make the helmet body firmly cover the head. During operation, the LED lamp 103 is powered by the battery 105. According to the specific operation scene, the specific irradiation direction of the LED lamp 103 can be adjusted; when the LED lamp 103 needs to be held by hand for operation, the LED lamp 103 is manually pulled out, and the adjustment seat 115 is disengaged from the limit seat 108 at this time, and then the personnel can hold the adjustment seat 115. During this process, the original rotation angle of the first knob 112 and the second knob 114 will not change, that is, after the adjustment seat 115 is retracted into the limit seat 108, the originally adjusted irradiation angle of the LED lamp 103 will not change; after the operation of holding the LED lamp 103 is completed, the retraction rod 109 is manually lifted, and the LED lamp 103 is automatically retracted, and the LED lamp 103 moves with the helmet body.
[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
