DETAILED DESCRIPTION

In combination with Figures 1 to 9, this embodiment provides a portable tool lamp, including a base 1 and a lamp body assembly 3, one end of the lamp body assembly 3 can be rotatably connected to the base 1, and a rotating shaft seat 102 is provided on the base 1. The lamp body assembly 3 is suitable for being rotatably connected to the base 1 through a rotating member connected to the rotating shaft seat 102, and a protrusion 1021 is provided on the rotating shaft seat 102, and a groove 3011 matching the protrusion 1021 is provided on the lamp body assembly 3, and the protrusion 1021 is suitable for being stuck in the groove 3011 when the lamp body assembly 3 is attached to the base 1 so that the lamp body assembly 3 and the base 1 remain in a fitted state.

In this embodiment, the base 1 and the lamp body assembly 3 can rotate between 0 and 180 degrees, so that free adjustment at multiple angles can be achieved. In this embodiment, the rotating member adopts a damping shaft 2. By setting the damping shaft 2, the lamp body assembly 3 and the base 1 can be maintained at any angle to be fixed at the angle adjusted by the user. In this embodiment, the two ends of the damping shaft 2 are respectively fixedly connected to the base 1 and the lamp body assembly 3. Here, one or two damping shafts 2 can be provided. Taking the provision of one damping shaft 2 as an example, at this time, one end of the lamp body assembly 3 is used to fix the damping shaft, and the other end is set to be hollow to facilitate the connection of wires between the power supply and the lamp body.

As shown in FIG. 1 to FIG. 5 , one end of the base 1 is upwardly protruded toward one side of the lamp body assembly 3 and is provided with a shaft seat 102, and a positioning hole 1022 is provided on the shaft seat 102. A first plug-in connector and a second plug-in connector perpendicular to each other are fixedly provided on both end surfaces of the damping shaft to fix the base 1 and the lamp body assembly 3 respectively, and the first plug-in connector is suitable for being inserted into the positioning hole 1022, so as to fix the damping shaft 2 on the shaft seat 102. The second plug-in connector can be fixedly connected to the housing of the lamp body assembly 3 by integral injection molding or pin-hole bolting. In order to prevent the lateral shear force caused by the frequent rotation of the lamp body assembly 3 relative to the base 1 from affecting the loosening of the positioning hole 1022 or the damping shaft 2, resulting in a virtual position when the lamp body assembly 3 rotates relative to the base 1, a plurality of reinforcing ribs 1023 are provided around the positioning hole 1022. For example, in one embodiment, at least three reinforcing ribs 1023 are provided and fixed in a triangular shape. In this embodiment, a rotatable side of the lamp body assembly 3 is provided with an accommodation space to accommodate the shaft seat 102. Here, the groove 3011 is provided in the accommodation space so that the protrusion 1021 enters the groove 3011 in the accommodation space when fitted. The lamp body assembly 3 can be configured to be similar to or fitted with the base 1, and one end thereof connected to the base 1 is provided with a recess to form the accommodation space, and the other end can be provided with a switch button for user convenience.

As shown in FIG. 1 to FIG. 5 and FIG. 8 , the protrusion 1021 is arranged on the shaft seat 102, and has a certain elastic deformation ability, so that when the lamp body assembly 3 is attached to the base 1, it can match with the groove 3011 in the lamp body assembly 3 to form a structure similar to a snap connection, and when the lamp body assembly 3 is separated from the base 1, a little force is required to overcome the elastic force of the protrusion 1021. This arrangement makes the connection between the lamp body assembly 3 and the base 1 more stable when attached and stored, and will not automatically loosen or rotate, which is convenient for users to transport and transfer. In this embodiment, the cross-section of the protrusion 1021 is a trapezoid, and the upper base 10211 of the trapezoidal protrusion 1021 is the shortest side. The length of its lower waist 10213 is shorter than that of the upper waist 10212, and an angle of 110° to 130° is set between the upper base 10211 and the lower waist 10213, and the angle is preferably 120°. An angle less than or equal to 150° is set between the upper waist 10212 and the upper base 10211, and the angle is preferably 145°, to ensure that when the lamp body assembly 3 is separated from the base 1 and opened for use, the protrusion 1021 can smoothly detach from the groove 3011 and unfold.

In another embodiment, when the base 1 and the lamp body assembly 3 are fitted, the distance between the upper bottom edge 10211 of the protrusion 1021 and the groove 3011 is at least 0.2 mm, so as to prevent the deformation of the shaft seat 102 due to processing and production from affecting the fit between the protrusion 1021 and the groove 3011. In this embodiment, when the protrusion 1021 is buckled into the groove 3011, the lamp body assembly 3 and the base 1 are tightly fitted. In this embodiment, the protrusion 1021 is arranged toward the contact surface between the base 1 and the lamp body assembly 3; and the other surface of the base 1 that is not in contact with the lamp body assembly 3 is arranged as a battery coupling surface for battery insertion.

In one embodiment, the shaft seat 102 includes a shaft cover 103, and the shaft cover 103 is used to enclose the damping shaft 2 in the shaft seat 102. Here, the protrusion 1021 can be connected to the shaft cover 103 through an elastic arm, and the protruding part of the protrusion 1021 is directed toward the long side direction of the base 1.

In another embodiment, a receiving groove 101 suitable for receiving the hook 4 is provided on one side of the base 1 facing the lamp body assembly 3, and the hook 4 is rotatably provided in the receiving groove 101. Here, a ball head 401 is connected to the end of the hook 4, and a ball socket 1012 suitable for the movement of the ball head 401 is provided in the receiving groove 101. The ball head 401 can be integrally injection molded with the hook 4, and the hook 4 is rotatably connected to the base 1 through the ball head 401, so that the hook 4 can be rotated on the base 1, and when stored, the hook 4 can be stored in the receiving groove 101 by rotating it, and the lamp body assembly 3 can cover the receiving groove 101. In order to prevent the hook 4 from swinging and play a positioning role, a plurality of protrusions 1011 that can position the hook 4 are arranged on the side wall of the receiving groove 101. When inserted, the protrusion 1011 is interference-connected with the hook 4, and the hook 4 is inserted after deformation, so it can play a limiting role.

As shown in combination with Figures 3 to 5, in one embodiment, a movable support member 5 is detachably connected to the side end of the base 1 for rotation and transfer. Here, the movable support member 5 is located on the other side of the base 1 opposite to the rotating shaft seat 102. The movable support member 5 includes a support body and a movable body. The support body can be connected to the base 1 by threads or other means. The movable body includes at least one rotating element that can be set in other activity spaces. The movable body can be detachably connected to other surfaces or components (i.e., fixed parts) to achieve universal rotation and transfer of the lamp body assembly 3.

As shown in FIG. 7 , in this embodiment, the lamp body assembly 3 includes a housing 301, and a lens 302, a lamp board 303, and a heat sink 304 are sequentially arranged from top to bottom in the housing 301 based on the light-emitting surface, and a reflector is arranged on the outer ring of the lamp board 303, and the reflector has a bevel, and the angle of the bevel of the reflector relative to the plane where the lamp board 303 is located is 120° to 160°, so as to achieve the light source focusing effect. A number of positioning holes 1022 are provided on the lamp board 303, so as to fix it with the heat sink 304 for better heat dissipation. Here, the side of the heat sink 304 is provided to wrap the ribs of the lamp board 303 to realize the multi-directional heat extraction of the lamp board 303. The heat sink 304 is made of aluminum, a metal part with good thermal conductivity, and is connected to the lamp board 303 through ribs to increase the connection area with the lamp board 303, thereby realizing the heat extraction from multiple and all-round directions and improving the heat dissipation effect.
