Description

Technical Field

[0001] This utility model relates to the field of lighting tools technology, and more specifically, to a work lamp. Background Technology

[0002] Work lights are a common type of lighting equipment. There are many types of work lights, including floodlights and panel lights. Work lights not only provide illumination but also serve a decorative purpose. They are commonly used in various workplaces, such as offices, workshops, workbenches, outdoors, and underground, to provide lighting for people while they work.

[0003] However, most existing work lights have relatively simple structures. When users want the work light to illuminate at a specific angle, this is often not possible due to the limitations of the work light structure, thus failing to meet different user needs.

[0004] To this end, Chinese Patent Publication No. CN222798888U discloses a work lamp. In this work lamp structure, the base can provide support, while the lamp body is rotatably connected to the hinge seat on the upper side of the base through a hinge shaft, thereby realizing the free adjustment of the illumination angle of the lamp body. After adjusting to the required angle, the hinge shaft is locked relative to the hinge seat by the adjustment wheel, thereby fixing the illumination angle of the lamp body.

[0005] However, in the above-mentioned work light structure, when the angle of the work light needs to be adjusted, the user first needs to loosen the adjustment wheel, and then start to adjust the angle of the lamp body relative to the base. After the angle of the lamp body relative to the base is adjusted, the adjustment wheel needs to be tightened again to control the hinge shaft to lock relative to the hinge seat. This has the disadvantage of inconvenient operation, that is, the disadvantage of troublesome lamp body illumination angle adjustment. Utility Model Content

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 See Figure 1-7As shown in the figure, this application discloses a work lamp, including a base 1 and a lamp body 2; the lower end of the base 1 is provided with a notch 11, and the middle of the lower end of the lamp body 2 is provided with an outwardly protruding hinge part 21, which is inserted into the notch 11, and the two ends of the hinge part 21 abut against the two ends of the notch 11. The lamp body 2 is rotatably connected to the base 1 via the hinge part 21; a first ratchet structure is provided between the hinge part 21 and the base 1. When the lamp body 2 rotates relative to the base 1, the first ratchet structure is used to lock the lamp body 2 in the state after rotating relative to the base 1.

[0024] Both ends of the hinge 21 are provided with a first rotating shaft 22, and both sides of the notch 11 are provided with a first shaft hole 12. The two first rotating shafts 22 are inserted into the first shaft hole 12 on the corresponding side and are rotatably connected to the first shaft hole 12. A first ratchet structure is provided between one of the first rotating shafts 22 and the base 1. With this structure, the lamp body can be reliably rotatably connected to the base under the cooperation of the first rotating shaft and the first shaft hole.

[0025] The first ratchet structure includes a first sliding seat 31, a first spring 32, and a screw 33. The first sliding seat 31 is horizontally slidably connected to the inside of the base 1 located on one side of the notch 11 and is rotatably limited by the base 1. The first sliding seat 31 has a plurality of first ratchet teeth 311 circumferentially arranged on the side facing the notch 11. The end of the first rotating shaft 22 located on one side of the first sliding seat 31 is provided with a first ratchet groove 221 corresponding to the plurality of first ratchet teeth 311. The screw 33 moves through the first sliding seat 31 and is axially threadedly fastened to the first rotating shaft 22 located on one side of the first sliding seat 31. The first spring 32 is sleeved on the outside of the screw shank of the screw 33. The two ends of the first spring 32 are respectively pressed against the head of the first sliding seat 31 and the head of the screw 33. The first spring 32 is used to fasten the first sliding seat 31. 1. A spring force is applied toward the hinge 21 to make each first ratchet 311 engage with the corresponding first ratchet groove 221. By adopting this first ratchet structure, when the lamp body rotates relative to the base, each first ratchet can disengage from the previous first ratchet groove and engage with the next first ratchet groove under the action of the first spring. Thus, when the lamp body is released, the lamp body and the base can be relocked, that is, the lamp body can be locked in the state after rotation relative to the base, so that the lighting direction of the lamp body is locked. In addition, during the disengagement and engagement of the first ratchet and the first ratchet groove, the first sliding seat can slide horizontally relative to the base. The outer contour of the first sliding seat is a rectangular structure. After the first sliding seat is slidably engaged with the base, it can prevent the first sliding seat from rotating relative to the base.

[0026] The work light also includes a handle 4; a second rotating shaft 41 is provided on the inner side of both ends of the handle 4, and a second shaft hole 13 is provided on both sides of the base 1. The two second rotating shafts 41 are respectively inserted into one of the second shaft holes 13 and rotatably connected to the second shaft hole 13; a second ratchet structure is provided between the handle 4 and the base 1; the second ratchet structure includes two second sliding seats 5 slidably connected to the inner side of the base 1, the two second sliding seats 5 are respectively arranged opposite to one of the second rotating shafts 41, each second sliding seat 5 has a plurality of second ratchet teeth 51 circumferentially arranged on the side facing the corresponding second rotating shaft 41, each second rotating shaft 41 has a plurality of second ratchet grooves 411 circumferentially arranged on the side facing the corresponding second sliding seat 5, and a second spring 52 is embedded between the inner end of each second sliding seat 5 and the inner wall of the base 1. Both springs 52 are used to apply a spring force to the second sliding seat 5 on the side of the corresponding second rotating shaft 41 so that each second ratchet 51 is engaged with the second ratchet groove 411 at the corresponding position. With the handle, it is convenient to carry the work light when holding the handle, and the handle can be used as a support after the handle is rotated relative to the work light. Furthermore, when the handle is rotated relative to the base, each second ratchet can disengage from the previous second ratchet groove and engage with the next second ratchet groove under the action of the second spring, so that the handle can be kept in the adjusted position when the handle is stopped rotating. In addition, during the manual rotation of the handle, the outer contour of the second sliding seat is a rectangular structure, and after the second sliding seat is slidably engaged with the base, it can prevent the second sliding seat from rotating relative to the base.

[0027] The work light also includes a hook 6; the hook 6 is rotatably connected to the front side of the upper end of the base 1, and the front side of the base 1 is also provided with a storage groove 14; when the hook 6 is rotated and folded relative to the base 1, the hook 6 is stored in the storage groove 14; through the setting of the hook, when the hook body is rotated to the outside of the base, the work light can be hung up for use, thereby making the use of the work light more convenient. After the hook is used up, it can be rotated back into the storage groove so that the storage groove can store the hook.

[0028] A control circuit board 71 is fixed inside the base 1, and the lamp body 2 is electrically connected to the control circuit board 71 via a wiring harness. The base 1 is equipped with a charging interface 72 and a power indicator light group 73, both of which are electrically connected to the control circuit board 71. A dust plug 15 is attached to the base 1 to cover the charging interface 72 and the power indicator light group 73. A control button group 16 is provided on the base 1, which triggers the control button group located on the control circuit board 71 to control the on / off state and color temperature of the lamp body 2. Through the charging interface, when a charging cable is connected to the charging interface, i.e. It can charge the battery fixed inside the base or the battery pack connected to the outside of the base. The power indicator light group can indicate the remaining power of the battery or battery pack. The control button group can trigger the control button group located on the control circuit board to control the light body's on / off state and light emission color temperature. For example, one button in the control button group is used to trigger one control button on the control circuit board to control the light panel's on / off state, and another button in the control button group is used to trigger another control button on the control circuit board to control the light panel's light emission color temperature.

[0029] A storage battery 8 is fixed inside the base 1, and the control circuit board 71 is electrically connected to the storage battery 8. By embedding the storage battery inside the base, the storage battery can directly power the control circuit board, and it has the advantage of simple structure.

[0030] Several magnets 9 are embedded in the rear side of the base 1; after the magnets are embedded in the rear side of the base, the work lamp can be magnetically attached to the ferromagnetic support body for easy use.

[0031] The base 1 has a threaded connection hole 18 on its rear side, which is used to connect with the stud on the tripod. By providing a threaded connection hole on the rear side of the base and connecting it with the stud on the tripod, the tripod can support the work light for use, thereby improving the practicality of the work light.

[0032] Example 2 See Figures 8-10As shown, unlike Embodiment 1, the work light also includes an adapter 10 for mounting a battery pack; a mounting cavity 19 is provided on the rear side of the base 1, and sliding grooves 191 are formed on both sides of the mounting cavity 19 for sliding the sliders 101 located on both sides of the adapter 10 into the grooves; an elastic pressing block 192 is connected to the base 1; when the sliders 101 on the adapter 10 slide into the sliding grooves 191, the elastic pressing block 192 abuts against the lower end of the adapter 10 to prevent the adapter 10 from detaching from the base 1; a conductive socket 74 is provided on the top of the mounting cavity 19, and the conductive socket 74 is connected to the control circuit board. 71 Electrical connection: A conductive plug 102 is provided at the upper end of the adapter 10. The conductive plug 102 mates with the conductive socket 74 for electrical connection. A conductive insert assembly 103 is fixed on the adapter 10. The conductive insert assembly 103 is used to mate with the conductive end of the battery pack for electrical connection. The conductive plug 102 is electrically connected to the conductive insert assembly 103. With this structure, after the battery pack is installed on the adapter, the conductive end on the battery pack can mate with the conductive insert assembly on the adapter for electrical connection. Furthermore, after the adapter is inserted into the mounting cavity, the sliders on both sides of the adapter can slide into the grooves. In this configuration, the elastic pressing block abuts against the lower end of the adapter to prevent it from detaching from the base, thus locking the adapter to the base. After the adapter and base are assembled, the conductive plug on the adapter can engage with the conductive socket on the base. At this point, the battery pack mounted on the adapter can supply power to the control circuit board via the conductive inserts, the conductive plug, and the conductive socket. When it is necessary to remove the adapter from the base, press the elastic pressing block to release it from its abutment against the lower end of the adapter, allowing the adapter to be removed from the base. The aforementioned battery pack and... The adapter is detachable, allowing for easy replacement of the battery pack when it runs out of power, thus facilitating the use of the work light. In the above structure, when using a different type of battery pack, there is no need to install the adapter on the base; the battery pack can be directly installed in the mounting cavity. This allows the protrusions on both sides of the battery pack to slide directly into the grooves on the base, and the lower end of the battery pack to abut against the elastic pressing block. This locks the battery pack to the base. The battery pack is also equipped with conductive connectors that can directly connect to conductive sockets to supply power to the control circuit board.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
