[0002] Work lights are common lighting products in our daily lives, and they are highly sought after by consumers in both work and outdoor settings. Existing work lights typically use a threaded connection between the lamp head and lamp holder, making installation and removal cumbersome and time-consuming. This makes it difficult for users to quickly and conveniently install or remove the lamp head from the lamp holder. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a work lamp, which realizes quick and convenient installation and disassembly of lamp holders through axial limitation of a first limiting protrusion and a second limiting protrusion, thereby improving the user experience.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A work lamp comprises: a lamp head, and a lamp holder for detachably mounting the lamp head, wherein the lamp head is provided with a lamp head mounting portion, and the lamp holder is provided with a lamp head mounting groove matching the lamp head mounting portion for inserting the lamp head mounting portion;

[0006] A first limiting protrusion protruding radially outward is provided on the side wall of the lamp holder mounting portion; a second limiting protrusion protruding radially inward is provided on the inner wall of the lamp holder mounting groove; a limiting inlet and outlet are provided on the inner wall of the lamp holder mounting groove at one end of the second limiting protrusion along its circumferential direction; and the size of the limiting inlet and outlet is not less than that of the second limiting protrusion and matches the size;

[0007] The distance between the side of the first limiting protrusion away from the axis of the lamp holder mounting part and the axis of the lamp holder mounting part is greater than the distance between the side of the second limiting protrusion facing the axis of the lamp holder mounting groove and the axis of the lamp holder mounting groove, and the distance between the side of the first limiting protrusion away from the axis of the lamp holder mounting part and the axis of the lamp holder mounting part is less than the distance between the side of the second limiting protrusion away from the axis of the lamp holder mounting groove and the axis of the lamp holder mounting groove.

[0008] With the above structure, when the user wants to install the lamp cap on the lamp holder, he only needs to align the first limiting protrusion on the lamp cap mounting portion with the limiting inlet and outlet on the lamp cap mounting slot; then operate the lamp cap mounting portion to insert into the lamp cap mounting slot along the direction of entering the lamp cap mounting slot until the first limiting protrusion is axially lower than the second limiting protrusion; finally, rotate the lamp cap mounting portion so that the first limiting protrusion moves below the second limiting protrusion, thereby achieving the installation of the lamp cap on the lamp holder; at this time, due to the cooperation between the first limiting protrusion and the second limiting protrusion, the lamp cap mounting portion is restricted from axially disengaging from the lamp cap mounting slot;

[0009] If the user wants to remove the lamp head from the lamp holder, he only needs to reverse the operation; that is, rotate the lamp head mounting portion so that the first limiting protrusion is aligned with the limiting inlet and outlet, and then operate the lamp head mounting portion to leave the lamp head mounting slot in the direction of leaving the lamp head mounting slot;

[0010] The above structure makes the assembly and disassembly of the lamp head and the lamp holder more convenient and quick, and has a simple structure.

[0011] Furthermore, a plurality of first limiting protrusions are provided on the side wall of the lamp holder mounting portion; and the plurality of first limiting protrusions are distributed along the circumferential spacing of the lamp holder mounting portion; a plurality of second limiting protrusions are provided on the inner wall of the lamp holder mounting groove, and the plurality of second limiting protrusions are distributed along the circumferential spacing of the lamp holder mounting groove, and the spacing between two adjacent second limiting protrusions forms the limiting inlet and outlet; the number and distribution positions of the limiting inlet and outlet match the number and distribution positions of the first limiting protrusions.

[0012] The above-mentioned structure makes the structure of the lamp holder mounting part and the structural setting of the lamp holder mounting groove more reasonable and reliable; the setting of multiple first limiting protrusions and multiple second limiting protrusions enables the lamp holder mounting part to be more stably and reliably installed in the lamp holder mounting groove; specifically, multiple first limiting protrusions are distributed at equal intervals along the circumference of the lamp holder mounting part, and multiple second limiting protrusions are distributed at equal intervals along the circumference of the lamp holder mounting groove; four first limiting protrusions are provided, and four second limiting protrusions are provided.

[0013] Furthermore, the work lamp includes a lamp holder elastic structure, and the lamp holder elastic structure acts on the lamp holder so that the lamp holder mounting portion has a tendency to move in a direction of disengaging from the lamp holder mounting groove;

[0014] One end of the lamp holder mounting portion is preferentially inserted into the lamp holder mounting groove to form a lamp holder priority insertion end; the width of the first limiting protrusion is greater than the width of the second limiting protrusion; and a limiting slot is provided on the end face of the first limiting protrusion away from the lamp holder priority insertion end, and the limiting slot is matched with the second limiting protrusion to limit the relative circumferential movement between the first limiting protrusion and the second limiting protrusion. Specifically, the circumferential width of the limiting slot is not less than the circumferential width of the second limiting protrusion.

[0015] With the above structure, during the process of inserting the lamp holder mounting part into the lamp holder mounting slot, the user needs to apply a certain operating force to the lamp holder mounting part to overcome the force of the lamp holder elastic structure; when rotating the lamp holder mounting part so that the first limiting protrusion is located below the second limiting protrusion, and the limiting slot on the first limiting protrusion is opposite to the second limiting protrusion; at this time, when the user removes the force applied to the lamp holder mounting part, the lamp holder elastic structure will drive the lamp holder mounting part to move in the direction of disengaging from the lamp holder mounting slot until the first limiting protrusion is released. The first limiting protrusion contacts the second limiting protrusion, and the second limiting protrusion is snapped into the limiting groove; the first limiting protrusion cooperates with the second limiting protrusion to limit the separation of the lamp holder and the lamp base; the second limiting protrusion cooperates with the limiting groove to limit the relative circumferential movement between the first limiting protrusion and the second limiting protrusion, thereby preventing the lamp holder mounting portion from being disengaged from the lamp holder mounting groove due to accidental rotation between the lamp holder mounting portion and the lamp holder mounting groove, making the installation of the lamp holder mounting portion and the lamp holder mounting groove more reliable and stable;

[0016] If the user needs to disassemble the lamp holder, he only needs to apply a certain operating force to the lamp holder mounting portion to press down the lamp holder mounting portion so that the second limiting protrusion is separated from the limiting slot, and then rotate the lamp holder mounting portion.

[0017] Furthermore, the lamp holder elastic structure is arranged on the bottom surface of the lamp holder mounting groove.

[0018] The above structure makes the arrangement of the elastic structure of the lamp holder more reasonable and reliable.

[0019] Furthermore, the bottom surface of the lamp holder mounting groove is provided with a lamp holder elastic structure accommodating groove that matches the lamp holder elastic structure for accommodating the lamp holder elastic structure, and the side of the lamp holder elastic structure accommodating groove facing the opening of the lamp holder mounting groove is provided with an extension port for the lamp holder elastic structure to extend out of the lamp holder elastic structure accommodating groove.

[0020] With the above structure, the setting of the lamp holder elastic structure accommodating groove can be used to limit and guide the expansion and contraction of the lamp holder elastic structure, ensuring that the lamp holder elastic structure is not twisted and deformed during the expansion and contraction process, ensuring the elastic force accuracy of the lamp holder elastic structure, and extending the life of the lamp holder elastic structure.

[0021] Furthermore, the lamp holder elastic structure includes a conductive member and a conductive member elastic member, wherein the conductive member elastic member acts on the conductive member so that the conductive member has a tendency to move toward the opening side of the lamp holder mounting slot;

[0022] At least the portion of the conductive member in contact with the lamp holder mounting portion is made of conductive material, and at least the portion of the lamp holder mounting portion in contact with the conductive member is made of conductive material.

[0023] With the above structure, the conductive member elastic member acts on the conductive member, and the conductive member acts on the lamp holder mounting portion, so that the lamp holder mounting portion has a tendency to move in a direction of disengaging from the lamp holder mounting groove;

[0024] The portion of the conductive member made of conductive material is electrically connected to the power supply in the lamp holder, and under the action of the conductive member elastic member, when the lamp holder is installed on the lamp holder, the conductive member is always in close contact with the lamp holder mounting portion; therefore, electrical connection between the conductive member and the lamp holder mounting portion can be achieved, and the portion of the lamp holder mounting portion made of conductive material is connected to the light source in the lamp holder to achieve power supply.

[0025] Furthermore, the bottom surface of the lamp holder mounting groove includes a bottom surface main body and a bottom plate, the bottom surface main body is provided with a bottom through-hole, and the side wall of the bottom through-hole extends axially to form a first surrounding wall, the bottom plate is provided on a side of the first surrounding wall away from the opening of the lamp holder mounting groove, and the first surrounding wall and the bottom plate together form the lamp holder elastic structure accommodating groove;

[0026] Furthermore, the conductive part includes a conductive part body, and the side wall of the conductive part body is provided with a conductive part limiting portion protruding radially outward; the first surrounding wall is opened inwardly toward the side of the lamp holder mounting groove opening to form the protruding port; the aperture of the protruding port is not less than the diameter of the conductive part body, and the distance between the end of the conductive part limiting portion away from the conductive part body and the axis of the conductive part body is greater than the radius of the protruding port.

[0027] With the above structure, the extension port cooperates with the limiting portion of the conductive member to limit the axial movement of the conductive member, preventing the conductive member from escaping from the accommodating groove of the lamp holder elastic structure, thereby ensuring stable and reliable operation of the lamp holder elastic structure.

[0028] Furthermore, the conductive member elastic member is arranged between the bottom plate and the conductive member, and two ends of the conductive member are respectively in contact with the bottom plate and the conductive member.

[0029] By adopting the above structure, the conductive member elastic member acts on the conductive member so that the conductive member has a tendency to move toward the opening side of the lamp holder installation slot; specifically, the conductive member elastic member is a spring.

[0030] Furthermore, the conductive member, the bottom plate and the conductive elastic member are made of conductive materials.

[0031] With the above structure, when the bottom plate is electrically connected to the power source in the lamp holder, the conductive member is electrically connected to the bottom plate via the conductive member elastic member, thereby achieving electrical connection between the conductive member and the power source in the holder.

[0032] Furthermore, the inner wall of the lamp holder mounting groove converges inwardly on a side of the second limiting protrusion away from the lamp holder mounting groove opening to form a step surface, and the distance between the step surface and the second limiting protrusion matches the thickness of the first limiting protrusion;

[0033] The distance between one end of the step surface facing the axis of the lamp holder mounting groove and the axis of the lamp holder mounting groove is smaller than the distance between the side of the first limiting protrusion away from the axis of the lamp holder mounting portion and the axis of the lamp holder mounting portion.

[0034] With the above-mentioned structure, during the insertion process of the lamp holder mounting part, the first limiting protrusion will contact the step surface to limit further insertion, that is, the cooperation between the step surface and the first limiting protrusion limits the insertion depth of the lamp holder mounting part in the lamp holder mounting groove; and since the distance between the step surface and the second limiting protrusion matches the thickness of the first limiting protrusion, it will not affect the cooperation between the first limiting protrusion and the second limiting protrusion; the above-mentioned structure makes the structural setting of the lamp holder mounting groove more reasonable, can avoid excessive compression of the elastic structure of the lamp holder, and effectively extend its service life.

[0035] Furthermore, the step surface is arranged at an inclination, and along the direction from the bottom surface of the lamp holder mounting groove to its opening, the step surface gradually moves away from the axis of the lamp holder mounting groove;

[0036] One end of the lamp holder mounting portion that is preferentially inserted into the lamp holder mounting groove is formed as a lamp holder priority insertion end; along the direction in which the lamp holder mounting portion is inserted into the lamp holder mounting groove, the first limiting protrusion is inclined gradually approaching the axis of the lamp holder mounting portion from the side away from the axis of the lamp holder mounting portion toward the side of the lamp holder priority insertion end.

[0037] The above structure makes the structural arrangement of the step surface and the first limiting protrusion more reasonable, and the two can cooperate better.

[0038] Furthermore, along the direction from the opening of the lamp holder mounting groove to the bottom, the inner wall of the lamp holder mounting groove includes a first inner wall, a step surface, and a second inner wall in sequence, and the inner diameter of the second inner wall is larger than the inner diameter of the second inner wall; the step surface is used to connect the first inner wall and the second inner wall, and the second limiting protrusion is set on the first inner wall.

[0039] The above structure makes the structure of the lamp holder mounting groove more reasonable and facilitates actual production.

[0040] Furthermore, the lamp holder includes a lamp holder body, and the lamp holder mounting portion is provided on the lamp holder body;

[0041] The lamp holder body comprises a lamp holder connecting seat and one or more lamp bodies, and the lamp bodies are rotatably arranged on the lamp holder connecting seat.

[0042] The above structure makes the structural setting of the lamp head more reasonable, and the rotation setting of the lamp body makes it convenient for users to adjust the light output angle during use to adapt to more scenarios.

[0043] Furthermore, a lamp body mounting groove is provided on the lamp holder connecting seat, and a lamp body mounting bracket is provided on the lamp body that matches the lamp body mounting groove to be located in the lamp body mounting groove; the lamp body mounting bracket is rotatably installed in the lamp body mounting groove; specifically, coaxial rotating shaft holes are provided on opposite sides of the lamp body mounting groove; the lamp body mounting bracket is provided with a rotating shaft through-hole passing through itself; the rotating shaft through-hole is coaxially arranged with the rotating shaft hole and the lamp body mounting bracket is rotatably installed in the lamp body mounting groove by connecting the rotating shaft.

[0044] The above structure is adopted to realize the rotational connection between the lamp body and the lamp holder connecting seat.

[0045] Furthermore, the lamp bodies are distributed at intervals on the circumference of the lamp holder connecting base.

[0046] The above structure makes the distribution of the lamp bodies more reasonable. Specifically, the lamp bodies are distributed at equal intervals on the circumference of the lamp holder connecting base, and three lamp bodies are provided.

[0047] Furthermore, the lamp holder is provided with a hook capable of hanging the lamp holder on an external object and / or an adsorbent capable of adsorbing the lamp holder on an external object.

[0048] With the above structure, the hook can realize the hanging and fixing of the work light on other objects, the adsorbent can realize the adsorption of the work light on other objects, and the lamp holder itself can be placed on a horizontal plane; the above structure can realize multiple installations of the work light, so that the work light can adapt to more usage scenarios to meet the various needs of users.

[0049] Furthermore, the hook is rotatably arranged on the lamp holder to be unfolded or stored on the lamp holder.

[0050] With the above structure, when the hook is needed, the user only needs to rotate the hook to unfold it on the lamp holder; when the user does not want to use the hook, the user only needs to rotate the hook to store it in the lamp holder; this makes the setting of the hook more reasonable; by setting the hook on the bottom surface of the lamp holder, the rotatable hook can avoid the hook affecting the placement of the lamp holder on a horizontal surface.

[0051] Furthermore, the lamp holder is provided with a hook lock at the location where the hook is provided. When the hook is rotated and stored on the lamp holder, the hook lock acts on the hook to restrict the hook from rotating and unfolding.

[0052] With the above structure, when the hook is rotated and stored on the lamp holder, the hook lock can act on the hook, and the user needs to apply a certain operating force to rotate the hook to unfold it, effectively avoiding accidental unfolding of the hook, making the structural setting of the work lamp more reasonable.

[0053] Furthermore, the lamp holder is provided with a hook receiving groove that matches the hook and can be used to receive the hook; the hook receiving groove is provided with a hinge groove, and the hook is provided with a hinge column that is rotatably connected to the hinge, so as to realize the rotatable installation of the hook;

[0054] The lamp holder is provided with an adsorption member accommodating groove which matches the adsorption member and can be used to accommodate the adsorption member.

[0055] The above structure makes the structure of the lamp holder more reasonable. The hook receiving groove is arranged so that when the hook is received in the hook receiving groove of the lamp holder, the bottom surface of the lamp holder is flat, further preventing the hook from affecting the placement of the lamp holder on a horizontal surface.

[0056] The adsorption member is usually arranged on the bottom surface of the lamp holder, and the adsorption member is installed in the adsorption member accommodating groove, so that the bottom surface of the lamp holder is flat, thereby preventing the adsorption member from affecting the placement of the lamp holder on a horizontal surface.

[0057] Furthermore, the adsorption member is a magnetic member.

[0058] By adopting the above structure, the structural setting of the adsorption member is more reasonable and reliable, and the adsorption member can be adsorbed on magnetic materials or objects containing iron.

[0059] Furthermore, the lamp holder is also provided with a socket for supplying power to external electrical equipment.

[0060] With the above structure, the provision of the socket facilitates the connection of the work light with an external electrical device to supply power to the external electrical device, such as other work lights.

[0061] Furthermore, the lamp holder is provided with a control switch for controlling the working state of the lamp head.

[0062] The above structure makes the structural setting of the working lamp more reasonable, and facilitates the user to control the working state of the lamp head.

[0063] Furthermore, the lamp holder has a gripping portion for a user to hold.

[0064] With the above structure, the setting of the grip portion makes it easier for the user to hold the work light.

[0094] The above structure makes the structure of the lamp holder mounting part 101 and the structural setting of the lamp holder mounting groove 201 more reasonable and reliable; the setting of multiple first limiting protrusions 1011 and multiple second limiting protrusions 2011 enables the lamp holder mounting part 101 to be more stably and reliably installed in the lamp holder mounting groove 201; specifically, multiple first limiting protrusions 1011 are distributed at equal intervals along the circumference of the lamp holder mounting part 101, and multiple second limiting protrusions 2011 are distributed at equal intervals along the circumference of the lamp holder mounting groove 201; four first limiting protrusions 1011 are provided, and four second limiting protrusions 2011 are provided.

[0110] Furthermore, the conductive elastic member 302 is disposed between the bottom plate 2015 and the conductive member 301 , and two ends of the conductive member 301 are respectively in contact with the bottom plate 2015 and the conductive member 301 .

[0116] With the above structure, during the insertion process of the lamp holder mounting part 101, the first limiting protrusion 1011 will contact the step surface 2016 to limit further insertion, that is, the cooperation between the step surface 2016 and the first limiting protrusion 1011 limits the insertion depth of the lamp holder mounting part 101 in the lamp holder mounting groove 201; and since the distance between the step surface 2016 and the second limiting protrusion 2011 matches the thickness of the first limiting protrusion 1011, it will not affect the cooperation between the first limiting protrusion 1011 and the second limiting protrusion 2011; the above structure makes the structural setting of the lamp holder mounting groove 201 more reasonable, can avoid excessive compression of the lamp holder elastic structure 3, and effectively extend its service life.
