[0037] The utility model provides a floodlight.

[0038] In the embodiment of the present utility model, Figures 1 to 9As shown, the floodlight comprises a heat sink 1, a light emitting module 2, a frame 3 and a self-locking member 4. The heat sink 1 is formed with a heat dissipation groove 11 and an annular groove 12 arranged around the heat dissipation groove 11. The groove peripheral wall of the annular groove 12 comprises an outer annular wall 13 away from the heat dissipation groove 11. The outer annular wall 13 is provided with a through hole 131. The light emitting module 2 is arranged in the heat dissipation groove 11. The frame 3 is movably arranged on the heat sink 1. The frame 3 can move relative to the heat sink 1 to reciprocate between a fixed position and a disassembly position. The frame A part of the structure of the frame body 3 is used to abut against the light emitting module 2 when the frame body 3 is in the fixed position; another part of the structure of the frame body 3 is provided with a locking structure 311 corresponding to the through hole 131, and when the frame body 3 is in the fixed position, the locking structure 311 is located in the annular groove 12; when the frame body 3 is in the disassembly position, the frame body 3 is separated from the light emitting module 2; the self-locking member 4 passes through the through hole 131 and is detachably connected to the locking structure 311 in the annular groove 12 to limit the movement of the frame body 3 from the fixed position to the disassembly position.

[0039] Specifically explained, the main function of the heat sink 1 is to dissipate the heat generated by the light-emitting module 2 during operation, thereby keeping the temperature of the entire lamp within a safe range and extending the service life of the light-emitting module 2. The groove walls of the heat dissipation groove 11 and the annular groove 12 can be made of high thermal conductivity materials, such as aluminum or copper, to effectively conduct heat.

[0040] The light emitting module 2 is the light source part of the floodlight, responsible for generating the required illumination. It includes a circuit board, a light emitting chip, a transparent protective plate and other structures. When in contact with the frame 3, the transparent protective plate is in contact with the frame 3. Since the light emitting module 2 is a widely used module, its structure is described in more detail here.

[0041] The frame 3 is mainly used to fix and protect the light module 2, and also supports the assembly and disassembly operations of the lamp. It can be set in a ring shape, and the frame 3 can move by linear reciprocating movement or rotation. When the frame 3 moves in a linear reciprocating movement, the frame 3 can be connected to the heat sink 1 through a slide rail, and when the frame 3 moves in a rotational manner, the frame 3 can be connected to the heat sink 1 through a rotating shaft.

[0042] The connection between the self-locking part 4 and the locking structure 311 can be a magnetic connection, such as both include a magnetic structure (magnet, etc.), or it can be a plug-in connection, such as one of the two forms a hole structure and the other forms a plug-in structure with an inserted hole structure, or it can be a snap-in connection, such as both are provided with a snap-in structure, etc.

[0043] In order to fix the self-locking member 4 on the heat sink 1 , the self-locking member 4 may be connected to the through hole 131 by interference fit or threaded connection, which is not specifically limited herein.

[0044] The floodlight of the technical solution of the utility model not only provides additional space for structural reinforcement by setting the annular groove 12 around the heat dissipation groove 11, but also creates a special area for installing the locking structure 311 and the self-locking member 4. This design effectively isolates the light-emitting module 2 from the locking mechanism, ensures the heat dissipation efficiency, and avoids physical interference with the light-emitting module 2 during the locking or unlocking process.

[0045] In addition, since there is a certain spatial distance between the annular groove 12 and the light-emitting module 2, even if the outer annular wall 13 of the heat sink 1 is deformed when subjected to a large force impact, the annular groove 12 can effectively prevent such force from being transmitted to the light-emitting module 2. Therefore, this design effectively improves the durability and reliability of the light-emitting module 2, ensuring the stable operation and long service life of the floodlight under various environmental conditions.

[0046] Optionally, the frame body 3 includes a first annular wall 31. When the frame body 3 is in a fixed position, the first annular wall 31 is located in the annular groove 12, and the locking structure 311 is a locking hole 311a penetrating the first annular wall 31.

[0047] The self-locking member 4 can be inserted into the locking hole 311 a and abut against the inner wall of the locking hole 311 a to limit the movement of the frame 3 . The self-locking member 4 can also be moved out of the locking hole 311 a to avoid the movement of the frame 3 .

[0048] The locking hole 311a allows precise mechanical fit, which means that the self-locking member 4 can be precisely aligned and fixed with the locking hole 311a, thereby ensuring the stability of the frame 3 on the heat sink 1 and preventing any loosening or sliding, which is crucial for maintaining the correct position of the light-emitting module 2 and ensuring heat dissipation efficiency.

[0049] Optionally, a notch 312 is formed through the first annular wall 31, and the notch 312 extends in a diameter direction of the locking hole 311a. The notch 312 extends from the side edge of the first annular wall 31 to the hole wall of the locking hole 311a, and the width of the notch 312 is smaller than the diameter of the locking hole 311a.

[0050] The self-locking member 4 includes a transmission portion 41 and a flat portion 42. The transmission portion 41 is disposed through the through hole 131 and connected to the flat portion 42 in the annular groove 12. The flat portion 42 is disposed in a flat shape. The thickness of the flat portion 42 is smaller than the width of the notch 312. The width of the flat portion 42 is larger than the width of the notch 312 and smaller than the diameter of the locking hole 311a.

[0051] The transmission part 41 can move in the axial direction of the through hole 131 to drive the flat part 42 to move into the locking hole 311 a . The transmission part 41 can also rotate in the through hole 131 to drive the flat part 42 to rotate in the locking hole 311 a .

[0052] By allowing the flat portion 42 of the self-locking member 4 to simply rotate into or out of the locking hole 311a, the operation process is greatly simplified, so that the user can quickly lock or unlock the frame 3 without complicated disassembly steps. This design is particularly suitable for scenes where the operating space is limited or rapid operation is required in an emergency.

[0053] Because the locking and unlocking process only involves the rotational movement of the flat portion 42, the contact area with the inner wall of the locking hole 311a is small, which reduces the wear and tear that may be caused during long-term use and extends the service life of the component.

[0054] Optionally, the transmission part 41 is cylindrical, and the outer peripheral wall of the transmission part 41 is provided with an external threaded part 411;

[0055] The self-locking member 4 includes a nut 43 . The nut 43 is disposed in the annular groove 12 . The external threaded portion 411 is threadedly connected to the threaded portion of the nut 43 .

[0056] The transmission part 41 can be a screw or a bolt. By setting a nut 43, after the transmission part 41 rotates a certain angle, based on the abutment between the nut 43 and the outer annular wall 13, the transmission part 41 can be restricted from continuing to move in the annular groove 12, which is conducive to accurately controlling the depth and position of the flat part 42 entering the lock hole 311a.

[0057] Optionally, the nut 43 is connected to the wall surface of the outer annular wall 13 close to the annular groove 12 through a flexible pad 44 .

[0058] The flexible pad 44 plays a role of buffering and shock absorption, and can effectively reduce the direct hard contact between the nut 43 and the outer annular wall 13 caused by vibration or external impact. During the operation or maintenance of the floodlight, the flexible pad 44 can absorb some of the noise generated by the movement, especially during adjustment and locking operations, which can reduce the collision sound between metal parts and provide a quieter use environment.

[0059] In addition, when the user rotates the transmission part 41 to adjust the self-locking part 4, the flexible pad 44 can generate a certain resistance to the rotation process due to its physical properties. This resistance manifests as a damping feeling, which can be used as feedback to guide the user to perform more detailed operations.

[0060] Optionally, a rotation mark 132 is provided on the wall surface of the outer annular wall 13 away from the annular groove 12 . The rotation mark 132 is one or more of a text mark and a pattern mark. The rotation mark 132 is used to mark the rotation angle of the transmission part 41 in the through hole 131 .

[0061] Exemplarily, the text logo may be “unlock” and “lock”, and the pattern logo may be a locked door lock pattern and an opened door lock pattern, and no specific limitation is made here.

[0062] By setting a rotation mark 132 on the outer annular wall 13, the operator can intuitively see the current position of the transmission part 41 and its rotation angle. This intuitive feedback greatly simplifies the operation process. Especially when making fine adjustments, the operator can accurately determine the state and position of the self-locking part 4 according to the mark.

[0063] Proper marking can prevent over-rotation or under-rotation during operation, which may cause structural damage or locking failure. By clearly showing the proper range of rotation, accidents caused by improper operation can be avoided and the overall safety of the equipment can be enhanced.

[0064] Optionally, the frame 3 is rotatably disposed on the heat sink 1, and the frame 3 rotates to move between a fixed position and a disassembly position;

[0065] The notch 312 extends to the side edge of the first annular wall 31 close to the bottom wall of the annular groove 12 .

[0066] The pivoting design typically takes up less space because it does not require a long straight track for movement, but instead rotates around a fixed point. This makes the entire unit more compact and easier to install in space-constrained environments such as narrow aisles, under low roofs or in tight work areas.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
