AI Technical Summary
The support legs of existing lamps are prone to opening or closing automatically, which affects the user experience, and the existing locking structure is complex and costly.
A three-bladed movable work light was designed, which adopts a support foot structure with a knob switch lock and a locking plate. The support foot is prevented from moving accidentally by unfolding and closing the limiting groove, and the operation process is simplified.
This technology enables the stable deployment and closure of the support legs, improving product quality and ease of use while reducing production costs.

Abstract
Description
Technical Field
[0001] This utility model relates to a lighting device, and more particularly to a three-bladed movable work lamp. Background Technology
[0002] Existing similar lighting fixtures have the following drawbacks: the support legs tend to open or close automatically, affecting usability and product quality. Another type of similar lighting fixture with a support leg locking mechanism requires an independent locking mechanism on each support leg, resulting in high production costs and cumbersome operation, requiring careful opening and closing of the locking mechanism. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a three-bladed movable work lamp that addresses the shortcomings of the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following measures:
[0005] A three-blade movable work light includes a lamp body, with a top cover fixed at one end and a base fixed at the other end. Three lamp blade knob connectors are installed and fixed between the lamp body and the top cover. Lamp blades are rotatably connected to the lamp blade knob connectors, and lighting lamps are installed inside the lamp blades. The lighting lamps are electrically connected to a battery and a control circuit board inside the lamp body. A control switch for controlling the lighting lamps is installed on the lamp body. Three support legs are evenly distributed and rotatably installed on the side of the base. A knob switch lock for limiting the rotation of the support legs is rotatably installed at the middle of the outer side of the base. The edge of the knob switch lock has three locking plates that extend outward to lock the rotation of the three support legs. The knob switch lock has a lever for rotating the knob switch lock itself.
[0006] The support foot is provided with an unfolding limiting groove and a closing limiting groove that cooperate with the locking piece;
[0007] The three lamp blade knob connectors are evenly distributed along the circumference of the upper cover;
[0008] The base is provided with a rotating shaft rotatably connected to a rotary switch lock. The outer end of the rotating shaft is connected to a pressure cover to prevent the rotary switch lock from falling off. The lever passes through the through hole in the middle of the pressure cover and protrudes to the outside of the pressure cover.
[0009] The outer side of the base is rotatably connected to a hook, and the ball head on the hook is rotatably connected to the ball head groove of the base;
[0010] The base has three evenly spaced mounting slots for rotating mounting support legs on its side.
[0011] The three support legs are arranged alternately and at intervals.
[0012] The beneficial effects of this utility model are: practicality, novel structure, easy adjustment of the support feet, effective prevention of accidental opening or closing of the support feet, and improvement of product quality. Attached Figure Description

[0017] A three-blade movable work light includes a lamp body 5, with a top cover 1 fixed at one end and a base 6 fixed at the other end. Three lamp blade knob connectors 2 are installed and fixed between the lamp body 5 and the top cover 1. Lamp blades 3 are rotatably connected to the lamp blade knob connectors 2. An illumination lamp is installed inside the lamp blade 3. The illumination lamp is electrically connected to a battery and a control circuit board inside the lamp body 5. A control switch 501 for controlling the illumination lamp is installed on the lamp body 5. Three support legs 4 are evenly distributed and rotatably installed on the side of the base 6. A knob switch lock 8 for limiting the rotation of the support legs 4 is rotatably installed at the middle position of the outer side of the base 6. The edge of the knob switch lock 8 is provided with three locking plates 801 that extend outward to lock the rotation of the three support legs 4. The knob switch lock 8 is provided with a lever 802 for rotating the knob switch lock 8 itself.
[0018] like Figure 1-4 As shown, this state is the state where the support leg 4 is closed. Rotating to open the lamp leaf 3 allows control of the lighting by switching the power supply to the lamp leaf 3 via the control switch 501. When the support leg 4 is needed, simply rotate the rotary switch lock 8. Specifically, in the closed state, the support legs 4 are all pressed against the lamp body 5. At this time, the locking plate 801 of the rotary switch lock 8 falls into the closing limiting groove 402 of the support leg 4, and the support leg 4 cannot be rotated in this state. When the support leg 4 needs to be unfolded, rotate the rotary switch lock 8 by a certain angle using the lever 802. The locking plate 801 on the rotary switch lock 8 disengages from the closing limiting groove 402. At this time, the support leg 4 can be rotated to fully unfold it. After rotating the rotary switch lock 8 back, the locking plate 801 of the rotary switch lock 8 falls into the unfolding limiting groove 401 of the support leg 4, preventing the support leg 4 from accidentally closing. When it needs to be closed, follow the same steps as above and rotate the rotary switch lock 8.
[0019] The support leg 4 is provided with an unfolding limiting groove 401 and a closing limiting groove 402 that cooperate with the locking piece 801.
[0020] The three lamp blade knob connectors 2 are evenly distributed along the circumference of the upper cover 1.
[0021] The base 6 is provided with a rotating shaft 601 rotatably connected to a rotary switch lock 8. The outer end of the rotating shaft 601 is connected to a pressure cover 9 to prevent the rotary switch lock 8 from falling off. The lever 802 passes through the through hole 901 in the middle of the pressure cover 9 and protrudes to the outside of the pressure cover 9.
[0022] A hook 7 is rotatably connected to the outer side of the base 6, and the ball head 701 on the hook 7 is rotatably connected to the ball head groove 602 of the base 6.
[0023] The base 6 has three evenly spaced support foot mounting slots 603 for rotating and mounting support feet 4 on its side.
[0024] The three supporting legs 4 are arranged alternately and at intervals.
