[0033] Please refer to Figure 1 As shown, this embodiment provides a work lamp, which includes a lamp body (not shown in the figure), a battery pack 300, and an adapter 100. The lamp body is used to provide a lighting source. A rear cover 400 is provided at the rear of the lamp body, and a battery holder 200 is provided on the rear cover 400. The battery holder 200 is used to connect the adapter 100 and the lamp body. The adapter 100 is in plug-in fit with the battery pack 300 and is used to supply power to the lamp body. A limiting member 140 is provided inside the adapter 100 and is used to limit the battery pack 300. When in use, the battery pack 300 needs to be first assembled into the adapter 100, and then the adapter 100 and the battery holder 200 are assembled. During the assembly of the battery holder 200 and the adapter 100, the limiting member 140 moves upward along the axial direction of the mounting hole 132 to limit the battery pack 300, so that the battery pack 300 will not slip or shake during operation.
[0034] As Figures 1 to 8As shown in the figure, this embodiment provides a battery adapter. This adapter 100 can limit the battery pack 300, increasing the stability between the battery pack 300 and the adapter 100. This adapter 100 includes a housing 110 and a limiting member 140. The housing 110 is provided with a mounting hole 132 for assembling the limiting member 140. The limiting member 140 is restricted to move back and forth along the axis of the mounting hole 132 to limit the battery pack 300.
[0035] Furthermore, a driving member can be provided on the battery holder 200. When the adapter 100 is installed on the battery holder 200, the driving member starts to push the limiting member 140 to move upward along the axis to limit the battery pack 300, so that the battery pack 300 can be fixed on the adapter 100. When the adapter 100 is removed from the battery holder 200, the limiting member 140 can be pulled out of the battery pack 300 by the pulling force of the driving member to release the limitation on the battery pack 300. The limiting member 140 can also move downward along the axis of the mounting hole 132 by gravity to release the limitation on the battery pack 300.
[0036] Specifically, the housing 110 includes an upper cover 120 and a base 130. The upper cover 120 is assembled on the top of the base 130. The mounting hole 132 is provided on the base 130. The limiting member 140 includes a mating surface and a first limiting portion 141. The mating surface supports on the top surface of the base 130, and the first limiting portion 141 is inserted into the mounting hole 132. Preferably, the mounting hole 132 and the first limiting portion 141 are in clearance fit.
[0037] In the non-limiting state, the first limiting portion 141 can pass through the mounting hole 132 so that the battery pack 300 can be installed into the adapter 100. At this time, the top surface of the first limiting portion 141 is lower than the bottom surface of the battery pack 300.
[0038] In the limiting state, the bottom of the first limiting portion 141 is pushed, so that the limiting member 140 moves upward along the axis of the mounting hole 132, and the battery pack 300 is limited within the adapter 100.
[0039] Furthermore, in one embodiment, the adapter 100 is used for sliding assembly onto the battery holder 200. Guide surfaces are respectively provided on the front and rear sides of the first limiting portion 141 along the sliding assembly direction. The height of the guide surfaces is flush with or higher than the height of the assembly surface of the battery holder 200. Preferably, the height of the guide surfaces is higher than the height of the assembly surface, so that the limiting member 140 can move upward along the axis of the mounting hole 132 without interference when receiving a thrust force.
[0040] As Figure 6As shown, in this embodiment, at least two bumps 131 are provided on the top surface of the base 130. The at least two bumps 131 are respectively provided on both sides of the limiting member 140 to limit the movement of the limiting member 140 in the direction of the battery pack 300 coming out. Preferably, two bumps 131 are provided, and the interval between the two bumps 131 is equal to the size of the limiting member 140, so that the limiting member 140 can be stably maintained in the mounting hole 132 without coming out when the adapter 100 is pushed.
[0041] In order to make the battery pack 300 more firmly installed on the adapter 100, in one embodiment, the limiting member 140 includes a second limiting portion 142 and a third limiting portion 143 above the mating surface. The upper cover 120 is provided with a limiting groove 123, and the second limiting portion 142 extends into the limiting groove 123, thereby further ensuring the stability of the limiting member 140. The third limiting portion 143 cooperates with the battery pack 300 to limit the shaking of the battery pack 300 in the upper cover 120.
[0042] Specifically, the second limiting portion 142 and the third limiting portion 143 are spaced apart. The upper cover 120 includes a side wall, a first inner wall 121 located inside the side wall, and a second inner wall 122 located inside the first inner wall 121. The second limiting portion 142 is located between the side wall and the first inner wall 121, and the third limiting portion 143 is located between the first inner wall 121 and the second inner wall 122. A cavity is formed between the first inner wall 121 and the second inner wall 122 into which the bottom of the battery pack 300 can enter. When the first limiting portion 141 is forced to move upward, it pushes the third limiting portion 143 upward to the bottom of the battery pack 300 to limit the battery pack 300.
[0043] Furthermore, at least two limiting members 140 are included. The at least two limiting members 140 are respectively provided on the left and right sides of the adapter 100. Preferably, the limiting members 140 are provided on the left and right sides in the middle of the base 130.
[0044] Furthermore, in one embodiment, a slide rail 210 is provided on the battery holder 200, and a slider 150 is provided at the bottom of the adapter 100. The adapter 100 slides along the slide rail 210 to the mating position through the slider 150. At this time, the slide rail 210 is located between the slider 150 and the limiting member 140; during the assembly process of the adapter 100 and the battery holder 200, the slide rail 210 pushes the limiting member 140 to move upward along the axis direction of the mounting hole 132 to complete the installation and positioning of the rear cover 400 and the battery pack 300. Preferably, the length of the slide rail 210 can be 1 / 2 to 1 / 3 of the length of the slider 150. At this time, the battery holder 200 can push the limiting member 140 to the limiting state, and at the same time can reduce the weight of the product and make the work lamp more convenient to carry.
[0045] Specifically, a limiting hole 310 is provided on the bottom surface of the battery pack 300, and the limiting member 140 is engaged with the limiting hole 310. Preferably, the size of the limiting hole 310 is equal to the size of the third limiting portion 143, which can make the battery pack 300 more stably cooperate with the adapter 100.
