Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and more particularly to a lighting fixture. Background Technology

[0002] Lighting fixtures are indispensable equipment in daily life and work, and are widely used in various places such as homes, offices, and factories. As people's requirements for lighting quality and ease of use continue to increase, lighting fixtures with adjustable lighting angles and directions are becoming increasingly popular in the market.

[0003] Existing lighting fixtures typically consist of two main parts: a bracket and a lamp body. The lamp body needs to rotate and be adjusted relative to the bracket to meet different lighting angle requirements. However, existing lighting fixtures often use simple bushing structures or friction fixing methods to connect the lamp body and the bracket. These connections are prone to loosening over long-term use, causing the lamp body to be unable to maintain a stable angle position, thus affecting the stability of the lighting effect. Furthermore, existing connection structures often lack an effective positioning mechanism, making it difficult for users to accurately control the rotation range when adjusting the lamp body angle, hindering precise angle positioning and reducing ease of use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a lighting fixture that achieves stable relative rotation between the lamp body and the bracket through the cooperation of the first meshing part of the first rotating member and the second meshing part of the second rotating member, which facilitates the adjustment of the lighting angle and ensures smooth rotation and accurate positioning.

[0006] (II) Technical Solution

[0007] The solution adopted by this utility model to solve the above-mentioned technical problems is a lighting fixture, including a bracket;

[0008] The lamp body is rotatable relative to the bracket;

[0009] The bracket includes a first rotating member arranged opposite to both ends of the lamp body; the lamp body has a second rotating member at opposite ends, the first rotating member includes a first engaging portion arranged opposite to each other, and the second rotating member includes a second engaging portion capable of engaging with the first engaging portion.

[0010] In some embodiments, the bracket has a lamp body rotatably connected to one end on each of its opposite sides, and a mounting component for installation with an external structure is installed at the other end. The mounting component allows the entire lighting fixture to be installed on the external structure. The bracket is connected to the lamp body at one end and has a mounting component at the other end, supporting installation on various external structures (such as walls, ceilings, etc.) to adapt to different scenario requirements.

[0011] In some embodiments, the front end of the lamp body forms an illumination end face, and an LED bead is disposed within the illumination end face; the rear end of the lamp body is provided with a groove, and a control switch and a charging port are disposed within the groove; a cover plate is slidably connected to the top of the groove, and the cover plate does not completely cover the groove; when the cover plate slides to cover the charging port, the control switch is exposed; when the cover plate slides to cover the control switch, the charging port is exposed; the rear end of the lamp body is also provided with a magnetic attraction structure; the control switch and charging port are hidden within the groove and selectively exposed by the sliding cover plate, taking into account both dust prevention and ease of operation; the magnetic attraction structure expands the temporary fixing methods of the lamp (such as adsorbing onto metal surfaces).

[0012] By adopting the above scheme, the stable relative rotation between the lamp body and the bracket is achieved through the cooperation of the first meshing part of the first rotating part and the second meshing part of the second rotating part, which facilitates the adjustment of the lighting angle.

[0013] In some embodiments, the bracket is provided with a rotating groove on the outer wall near the first meshing part; the lamp body is provided with a rotating part adapted to the rotating groove.

[0014] By adopting the above solution, the cooperation between the rotating groove and the rotating part enhances the connection strength between the lamp body and the bracket, prevents it from detaching or shifting during rotation, and improves durability; in addition, the cooperation between the rotating groove and the rotating part provides precise rotation guidance, making the rotation smoother and more fluid.

[0015] In some embodiments, the lamp body includes an annular portion with a cavity inside. A partition wall is provided in the middle of the cavity, and a second rotating member is provided at both ends of the partition wall. The first rotating member can extend into the cavity and rotate in cooperation with the second rotating member.

[0016] In some embodiments, the annular portion is formed by a protrusion at one end of the lamp body, and the other end of the lamp body is a free end, so as to control the lamp body to rotate relative to the bracket about the central axis of the annular portion.

[0017] The above scheme uses a rotating mechanism arranged inside the cavity to save overall space; the partition wall provides structural support and enhances overall strength; the first rotating part extends into the cavity to increase the contact area and stability; the lamp body rotates unidirectionally around the axis of the annular part, simplifying the operation logic and avoiding the risk of wire entanglement caused by multi-directional rotation.

[0018] In some embodiments, an elastic element is provided between the partition wall and the second rotating member, the elastic element being capable of giving the second rotating member a tendency to always move in the direction of the first rotating member.

[0019] Using the above solution, the elastic element provides a continuous restoring force, continuously pressing the second rotating element to ensure that the first and second rotating elements always maintain good meshing, eliminating gaps caused by wear and maintaining accuracy; at the same time, it provides a certain operating resistance, improves the feel, increases rotational resistance, and prevents accidental rotation.

[0020] In some embodiments, a slot is provided at one end of the partition wall near the second rotating member, a fixing member is engaged in the slot, and the end of the fixing member away from the slot is connected to the second rotating member.

[0021] Using the above solution, the fastener is reliably fixed through the slot, and the snap-fit ​​design facilitates the disassembly and assembly of the second rotating component, making it convenient to replace worn parts or maintain the internal structure. At the same time, the fastener ensures the effective transmission of force from the elastic component.

[0022] In some embodiments, the fastener includes a fixing portion adapted to be in the slot, and a connecting portion extending outward from the middle of the fixing portion at one end away from the slot, the second rotating member being sleeved on the connecting portion and capable of moving along the axial direction of the connecting portion; and an anti-detachment portion is provided at the end of the connecting portion away from the fixing portion.

[0023] Using the above solution, the cooperation between the protrusion and the anti-detachment space prevents the second rotating part from axially disengaging, while allowing it to move slightly along the connecting part to adapt to the compression of the elastic part; and, the protrusion and the anti-detachment space can be locked by rotation, simplifying the assembly process.

[0024] In some embodiments, the anti-detachment portion includes a plurality of spaced protrusions formed by the end portion of the connecting portion extending radially outward; the second rotating member has a first through hole for the connecting portion to pass through at one end near the fixing member, and a plurality of spaced second through holes for the protrusions to pass through are provided around the first through hole, so that an abutment wall capable of abutting the protrusions is formed on the side of the second rotating member located at the second through hole, and the side wall of the abutment wall located inside the second rotating member extends axially in a direction away from the fixing member to form an extension wall; the extension wall and the abutment wall form an anti-detachment space between the second rotating member.

[0025] Specifically, the protrusions on the connecting part are adapted to the second through holes and extend into the second rotating member through the second through holes. The lamp body is rotated so that the protrusions rotate relative to the second through holes. When the protrusions are rotated into the anti-detachment space, the protrusions can be prevented from detaching from the second rotating member, thereby realizing the connection between the fixing member and the second rotating member.

[0026] Using the above solution, the protrusion passes through the second perforation and rotates into the anti-dislodgement space, forming a mechanical interlock; the extension wall restricts the axial displacement of the protrusion, ensuring connection reliability.

[0027] In some embodiments, the second rotating member has an inwardly recessed end facing the slot to form a mounting groove for mounting the elastic member; one end of the elastic member abuts against the bottom wall of the mounting groove, and the other end abuts against the fixing part.

[0028] Specifically, the mounting groove is an annular groove, which ensures that the elastic element is subjected to uniform force, avoids wear caused by uneven loading, and improves the smoothness of rotation.

[0029] In some embodiments, the inner wall of the cavity is provided with a limiting groove arranged along its axial direction, and the outer wall of the second rotating member is provided with a protruding rib that can fit into the limiting groove to limit the radial movement between the second rotating member and the lamp body.

[0030] By adopting the above solution, the fit between the groove and the rib can be restricted to prevent radial wobbling of the second rotating part, ensure the precise alignment of the first and second meshing parts, and reduce noise or jamming during rotation.

[0031] In some embodiments, the cavity is provided with the rotating portion at both ends of its axial opening; the outer wall of the first rotating member is provided with two spaced-apart annular protrusions, and the rotating groove is formed between the two annular protrusions.

[0032] By adopting the above scheme, the cooperation between the annular protrusion and the rotating groove restricts the axial displacement of the lamp body, while providing a fulcrum for rotation and enhancing the overall structural integrity.

[0060] like Figures 1-10 As shown, this utility model provides a lighting fixture, including a bracket 100 and a lamp body 200, the lamp body 200 being rotatable relative to the bracket 100; wherein, the bracket 100 includes first rotating members 101 arranged opposite to both ends of the lamp body 200; second rotating members 201 are provided at opposite ends of the lamp body 200, the first rotating member 101 including a first engaging portion 1011 arranged opposite to each other, and the second rotating member 201 including a second engaging portion 2011 capable of engaging with the first engaging portion 1011. In some embodiments, the lamp body 200 is rotatably connected to one end of opposite sides of the bracket 100, and a mounting member 300 for mounting to an external structure is installed at the other end; the entire lighting fixture can be installed on an external structure through the mounting member 300; the bracket 100 is connected to the lamp body 200 at one end and the mounting member 300 is provided at the other end, supporting installation on various external structures (such as walls, ceilings, etc.) and adapting to different scene requirements. In some embodiments, the front end of the lamp body 200 forms an illumination end face 206, and an LED bead is disposed within the illumination end face 206; the rear end of the lamp body 200 is provided with a groove 208, and a control switch 209 and a charging port 210 are disposed within the groove 208; a cover plate 211 is slidably connected to the top end of the groove 208, and the cover plate 211 does not completely cover the groove 208; when the cover plate 211 slides to cover the charging port 210, the control switch 209 is exposed; when the cover plate 211 slides to cover the control switch 209, the charging port 210 is exposed; the rear end of the lamp body 200 is also provided with a magnetic suction structure 212; the control switch 209 and the charging port 210 are hidden within the groove 208 and selectively exposed by the sliding cover plate 211, taking into account both dust prevention and ease of operation; the magnetic suction structure 212 expands the temporary fixing methods of the lamp (such as adsorbing metal surfaces). By adopting the above scheme, the stable relative rotation of the lamp body 200 and the bracket 100 is achieved through the cooperation of the first meshing part 1011 of the first rotating member 101 and the second meshing part 2011 of the second rotating member 201, which facilitates the adjustment of the lighting angle.

[0061] In some embodiments, the bracket 100 has a rotating groove 102 on its outer wall near the first engaging portion 1011; the lamp body 200 has a rotating portion 202 adapted to the rotating groove 102. With this solution, the cooperation between the rotating groove 102 and the rotating portion 202 enhances the connection strength between the lamp body 200 and the bracket 100, preventing disengagement or displacement during rotation and improving durability; furthermore, the cooperation between the rotating groove 102 and the rotating portion 202 provides precise rotation guidance, making rotation smoother. In some embodiments, the lamp body 200 includes an annular portion 203, which has a cavity 2031. A partition wall 2032 is provided in the middle of the cavity 2031, and second rotating members 201 are respectively provided at both ends of the partition wall 2032. The first rotating member 101 can partially extend into the cavity 2031 and rotate in cooperation with the second rotating member 201. In some embodiments, the annular portion 203 is formed by a protrusion at one end of the lamp body 200, and the other end of the lamp body 200 is a free end, so as to control the lamp body 200 to rotate relative to the bracket 100 about the central axis of the annular portion 203. With the above solution, a rotating mechanism is arranged inside the cavity 2031, saving overall space; the partition wall 2032 provides structural support, enhancing overall strength; the first rotating member 101 partially extends into the cavity 2031, increasing the contact area and stability; the lamp body 200 rotates unidirectionally about the axis of the annular portion 203, simplifying the operation logic and avoiding the risk of wire entanglement caused by multi-directional rotation.

[0062] In some embodiments, an elastic element 204 is provided between the partition wall 2032 and the second rotating member 201. The elastic element 204 provides the second rotating member 201 with a tendency to always move towards the first rotating member 101. With this solution, the elastic element 204 provides a continuous restoring force, continuously pressing the second rotating member 201 to ensure that the first rotating member 101 and the second rotating member 201 always maintain good engagement, eliminating gaps caused by wear and maintaining accuracy. Simultaneously, it provides a certain amount of operating resistance, improving the feel, increasing rotational resistance, and preventing accidental rotation. In some embodiments, a slot 2032a is provided at one end of the partition wall 2032 near the second rotating member 201. A fixing member 205 is engaged in the slot 2032a, and the end of the fixing member 205 away from the slot 2032a is connected to the second rotating member 201. Using the above solution, the fixing member 205 is reliably fixed through the slot 2032a. The snap-fit ​​design facilitates the disassembly and assembly of the second rotating member 201, making it convenient to replace worn parts or maintain the internal structure. At the same time, the fixing member 205 ensures the effective transmission of force from the elastic member 204. In some embodiments, the fixing member 205 includes a fixing part 2051 adapted to fit within the slot 2032a, and a connecting part 2052 extending outward from the middle of the fixing part 2051 at an end away from the slot 2032a. The second rotating member 201 is sleeved on the connecting part 2052 and can move axially along the connecting part 2052. Furthermore, an anti-detachment part 2053 is provided at the end of the connecting part 2052 away from the fixing part 2051. Using the above solution, the cooperation between the protrusion 2053a and the anti-detachment space 2016 prevents the second rotating member 201 from axially disengaging, while allowing it to move slightly along the connecting part 2052 to adapt to the compression of the elastic member 204; and, the protrusion 2053a and the anti-detachment space 2016 can be locked by rotation, simplifying the assembly process. In some embodiments, the anti-detachment portion 2053 includes a plurality of spaced protrusions 2053a formed by the end portion of the connecting portion 2052 extending radially outward; the second rotating member 201 is provided with a first through hole 2012 for the connecting portion 2052 to pass through at one end near the fixing member 205, and a plurality of spaced second through holes 2013 for the protrusions 2053a to pass through are provided around the first through hole 2012, so that an abutment wall 2014 capable of abutting against the protrusions 2053a is formed on the side of the second rotating member 201 located at the second through hole 2013, and the side wall of the abutment wall 2014 located inside the second rotating member 201 extends axially in a direction away from the fixing member 205 to form an extension wall 2015; the extension wall 2015 and the abutment wall 2014 form an anti-detachment space 2016 between the second rotating member 201.Specifically, the protrusions 2053a on the connecting portion 2052 are adapted to the second through holes 2013. After extending into the second rotating member 201 through the second through holes 2013, the lamp body 200 is rotated, causing the protrusions 2053a to rotate relative to the second through holes 2013. When the protrusions 2053a are rotated into the anti-detachment space 2016, the protrusions 2053a are prevented from detaching from the second rotating member 201, thus achieving the connection between the fixing member 205 and the second rotating member 201. Using the above scheme, after the protrusions 2053a pass through the second through holes 2013, they rotate and engage with the anti-detachment space 2016, forming a mechanical interlock; the extension wall 2015 restricts the axial displacement of the protrusions 2053a, ensuring connection reliability.

[0063] In some embodiments, the second rotating member 201 has an inwardly recessed mounting groove 2017 at one end facing the slot 2032a for mounting the elastic member 204; one end of the elastic member 204 abuts against the bottom wall of the mounting groove 2017, and the other end abuts against the fixing part 2051. Specifically, the mounting groove 2017 is an annular groove, which makes the elastic member 204 evenly stressed, avoids wear caused by uneven loading, and improves the smoothness of rotation. In some embodiments, the inner wall of the cavity 2031 is provided with a limiting groove 2033 arranged along its axial direction, and the outer wall of the second rotating member 201 is provided with a protruding rib 2018 that can fit into the limiting groove 2033 to limit the radial movement between the second rotating member 201 and the lamp body 200. By employing the above-described scheme, the engagement of the limiting groove 2033 and the protruding rib 2018 can prevent the second rotating member 201 from radially wobbling, ensuring precise alignment of the first meshing part 1011 and the second meshing part 2011, and reducing noise or jamming during rotation. In some embodiments, the rotating part 202 is provided at both ends of the cavity 2031 along its axial direction; the outer wall of the first rotating member 101 is provided with two spaced-apart annular protrusions 1012, and the rotating groove 102 is formed between the two annular protrusions 1012. By employing the above-described scheme, the engagement of the annular protrusions 1012 and the rotating groove 102 restricts the axial displacement of the lamp body 200, while providing a rotation fulcrum and enhancing the overall structural integrity.
