[0030] Reference Figures 1-6 The image shown is a preferred embodiment of the present invention.
[0031] The anti-loosening flashlight charging base provided by this utility model includes a housing 100. The top of the housing 100 has a charging groove 110 for the bottom of the flashlight 400 to be inserted. A limiting wall 111 is formed on one side of the charging groove 110, and a clamping member 200 is provided on the other side of the charging groove 110. The clamping member 200 has an abutment wall 112 arranged toward the limiting wall 111. A clamping area is formed between the limiting wall 111 and the abutment wall 112. The inner end of the clamping member 200 is movably connected to the housing 100. A reset structure is provided between the housing 100 and the clamping member 200.
[0032] Under the action of external force, the outer end of the clamping member 200 moves away from the limiting wall 111, and the clamping area becomes larger. When the bottom of the flashlight 400 is inserted into the clamping area, under the drive of the reset structure, the outer end of the clamping member 200 moves toward the limiting wall 111, and the abutment wall 112 abuts against the outer periphery of the flashlight 400, and the flashlight 400 is clamped and fixed in the charging slot 110.
[0033] The aforementioned anti-loosening flashlight charging base, by providing a charging slot 110 on the housing 100, allows the flashlight 400 to be placed in the charging slot 110 for charging. Then, through the synergistic action of the clamping member 200 and the reset structure, the housing 100 and the flashlight 400 are securely connected, thus preventing the flashlight 400 from loosening during charging. It is simple to operate, has a lightweight and reliable overall structure, and is highly practical.
[0034] like Figures 1-2 As shown, pressing down on the top of the clamping member 200 will cause the top of the clamping member 200 to move downward, thereby increasing the clamping area.
[0035] In some embodiments, the top of the clamping member 200 is connected to the housing 100, and the size of the clamping area can be changed by moving the bottom of the clamping member 200, which has high adaptability.
[0036] In this embodiment, the reset structure includes a longitudinally arranged longitudinal spring 210. One end of the longitudinal spring 210 is connected to the housing 100, and the other end is connected to the clamping member 200. The longitudinal spring 210 is in a compressed state. In this way, the elastic force drives the abutment wall 112 to abut against the outer periphery of the flashlight 400, achieving a stable connection.
[0037] In some embodiments, the reset structure may also be an elastic sheet, an elastic column, etc., which has good buffering properties.
[0038] A horizontally movable strip 300 is connected to the clamping member 200. The movable strip 300 extends laterally out of the clamping member 200 to form an extension. A limiting platform 1000 is provided on the housing 100 to restrict the downward movement of the extension. The limiting platform 1000 is located below the movable strip 300.
[0039] When the outer extension is directly above the limiting platform 1000, the clamping member 200 is locked. Thus, when the clamping member 200 is in the locked state, when an external force is applied to the clamping member 200, the outer extension is blocked by the limiting platform 1000, and the clamping member 200 cannot move downward, thereby achieving locking.
[0040] The clamping member 200 has a mounting hole through which the moving strip 300 passes. A limiting groove 201 is formed on the side wall of the mounting hole, extending along the extension direction of the mounting hole. A limiting bolt is provided in the moving strip 300, with the end of the limiting bolt protruding from the moving strip 300 and exposed in the limiting groove 201. In this way, the movement range of the moving strip 300 is controlled by the combined action of the limiting bolt and the limiting groove 201.
[0041] Specifically, the charging slot 110 is recessed. This makes the structure simple and compact.
[0042] As a preferred embodiment, refer to Figure 5 As shown, the upper part of the abutting wall 112 has an abutting protrusion 1120 protruding toward the clamping area, and the upper part of the limiting wall 111 has a limiting protrusion 1110 protruding toward the clamping area. The limiting protrusion 1110 and the abutting protrusion 1120 are arranged facing each other.
[0043] When the flashlight 400 is clamped and fixed in the charging slot 110, the bottom of the flashlight 400 is engaged in the charging slot 110 under the action of the limiting protrusion 1110 and the abutting protrusion 1120. In this way, it works with the outwardly flared flange on the outer periphery of the bottom of the flashlight 400 to make the connection structure more compact, the connection strength stronger, and achieve locking.
[0044] In this embodiment, the inner end of the clamping member 200 is hinged to the housing 100. The structure is simple and easy to install.
[0045] Specifically, the housing 100 has two longitudinally arranged copper pillars 120, the upper part of which is exposed in the charging slot 110. Thus, when the flashlight 400 is inserted into the charging slot 110, the bottom of the flashlight 400 presses against the copper pillars 120, achieving electrical connection.
[0046] In this embodiment, the copper pillar 120 is connected to an external power source via a circuit board, and the copper pillar 120 is used to charge the flashlight 400.
[0047] In some embodiments, refer to Figure 5 As shown, through the design of the limiting protrusion 1110, when the flange at the bottom of the flashlight 400 is engaged, the copper pillar 120 connects with the charging position on the flashlight 400, which is reliable and practical.
[0048] In a preferred embodiment, the copper pillar 120 is movably arranged, and a longitudinally arranged copper pillar spring 130 is fitted onto the lower part of the copper pillar 120. When the bottom of the flashlight 400 presses against the copper pillar 120 from top to bottom, the copper pillar 120 moves downward, and the copper pillar spring 130 is compressed. In this way, during the charging process, the copper pillar spring 130 is compressed, and under the action of elastic force, it ensures that the two copper pillars 120 can be forcefully and stably pressed against the charging position of the flashlight 400.
[0049] As a preferred embodiment, refer to Figure 5 As shown, during the charging process, the copper column spring 130 is compressed. Under the action of the elastic force, the flange on the outer periphery of the flashlight 400 abuts against the limiting protrusion 1110 and the abutting protrusion 1120, making the overall structure more compact and stable.
[0050] The housing 100 is provided with a power socket, and a power cord 400 is connected to the power socket.
[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
