[0025] As attached Figure 1 To be continued Figure 3As shown, a lamp with interchangeable accessories 2 for different lighting effects includes a lamp body 1 having a light outlet. The lamp body 1 has an annular groove 10 communicating with the light outlet. The annular groove 10 can be matched with various accessories 2 to achieve different lighting effects. At least two pressure plates 3 are provided at the light outlet of the lamp body 1. The outer peripheral surface of the accessory 2 is provided with a limiting part 21. Part of the pressure plate 3 protrudes from the inner wall of the annular groove 10 so that the protruding part of the pressure plate 3 can abut against the limiting part 21, thereby preventing the accessory 2 from coming out of the annular groove 10. At least one of the pressure plates 3 is movably connected to the lamp body 1. During the movement, the pressure plate 3 forms a pressing and locking position that can abut against the limiting part 21 and a disengaging and unlocking position that can disengage from the limiting part 21. Preferably, there are two pressure plates 3. One pressure plate 3 is fixedly connected to the lamp body 1. This fixed pressure plate 3 can be integrally formed with the outer shell of the lamp body 1 to form a limiting protrusion. The other pressure plate 3 is movably connected to the lamp body 1. According to the user's replacement needs, the user can operate the pressure plate 3 to switch back and forth between the pressing and locking position and the disengaging and unlocking position. When it is necessary to replace the accessory 2, the user operates the pressure plate 3 from the pressing and locking position to the disengaging and unlocking position. At this time, the original accessory 2 can be taken out from the annular groove 10, and the other accessory 2 required can be assembled into the annular groove 10. After that, the user operates the pressure plate 3 from the disengaging and unlocking position to the pressing and locking position to complete the locking. Compared with the prior art, this replacement structure can quickly complete the disassembly and installation, reduce the cumbersomeness of replacing accessories, and increase the stability of accessories.

[0026] As attached Figure 5 As shown, the limiting part 21 includes an annular flange 211 and / or a U-shaped groove 212. When the limiting part 21 is an annular flange 211, the bottom of the pressure plate 3 and the annular groove 10 form a limiting groove for the annular flange 211 of the accessory 2 to be inserted into. At this time, the accessory 2 is axially fixed and can rotate 360 ​​degrees in the circumferential direction. When the limiting part 21 is a U-shaped groove 212, the pressure plate 3 is inserted into the U-shaped groove 212. At this time, the accessory 2 is fixed in both the axial and circumferential directions.

[0027] In this embodiment, the pressure plate 3 is rotatably connected to the lamp body 1 via a rotating shaft 31. A spring 5 is provided between the pressure plate 3 and the lamp body 1 to drive the pressure plate 3 from the disengagement unlocking position to the pressing locking position. The pressing locking position is the position where the pressure plate 3 is held against the limiting part 21 under the elastic force of the spring 5. The disengagement unlocking position is the position where the pressure plate 3 disengages from the limiting part 21 after overcoming the elastic force of the spring 5, allowing the accessory 2 to be removed from the annular groove 10. The pressure plate 3 is held in place by the elastic force of the spring 5 to press and fix the accessory 2. When replacing, the user can press the end of the pressure plate 3 to make the head end of the pressure plate 3, i.e. the part of the pressure plate 3 that protrudes into the annular groove 10, tilt upwards to disengage from the pressing and facilitate the replacement of the accessory 2.

[0028] In this embodiment, a rotating shaft 31 is fixedly provided on one end face of the pressure plate 3. Both ends of the rotating shaft 31 extend to the outside of the two sides of the pressure plate 3. An opening groove 100 is provided on the lamp body 1 for the rotating shaft 31 to be accommodated. The pressure plate 3 is adapted to be installed in the opening groove 100 through the rotating shaft 31 so that the pressure plate 3 rotates relative to the lamp body 1, thereby realizing the rotation of the pressure plate 3.

[0029] In this embodiment, two fixing plates 4 are fixedly connected to the lamp body 1, respectively located on both sides of the pressure plate 3. The fixing plates 4 are provided with screw holes 41. The fixing plates 4 are fixedly connected to the lamp body 1 by fasteners passing through the screw holes 41, so that the fixing plates 4 cover part of the opening of the opening groove 100. During installation, the rotating shaft 31 of the pressure plate 3 is first placed in the opening groove 100, and then the fixing plates 4 are fixed to the lamp body 1 by fasteners, i.e. screws, to prevent the rotating shaft 31 from coming out of the opening of the opening groove 100.

[0030] In this embodiment, the fixing plate 4 is also provided with a positioning hole 42 or a positioning post, and the lamp body 1 is provided with a positioning post 11 or a positioning hole. The fixing plate 4 is adapted to the positioning post 11 or the positioning hole of the lamp body 1 through the positioning hole 42 or the positioning post. The fixing plate 4 can be quickly installed by the cooperation of the positioning hole and the positioning post.

[0031] As attached Figure 3 As shown, at least one first fixing post 32 is provided on one end face of the pressure plate 3, and the lamp body 1 is provided with a clearance space 101 that allows the pressure plate 3 to rotate to the disengagement and unlocking position. A second fixing post 12 corresponding to the first fixing post 32 is fixedly provided in the clearance space 101. One end of the spring 5 is sleeved on the first fixing post 32 and the other end is sleeved on the second fixing post 12, so that the pressure plate 3 always maintains elastic force, which is conducive to the reset and pressing of the pressure plate 3.

[0032] In this embodiment, an abutment block 13 is fixedly provided in the clearance space 101, which can abut against the end of the pressure plate 3 when the pressure plate 3 is rotated to the disengagement and unlocking position, to prevent the pressure plate 3 from rotating excessively, maintain the elasticity of the spring 5, and effectively prevent the spring 5 from losing its elasticity due to excessive fatigue.

[0033] As attached Figure 4 To be continued Figure 6 As shown, accessory 2 includes a spherical cover 200, a mesh component, and a cylindrical component. The mesh component includes a small-aperture mesh (honeycomb mesh) 201 and a large-aperture mesh 202; the cylindrical component includes a half-body cylinder 203 and a full-body cylinder 204. An annular flange 211 and a U-shaped groove 212 can be selectively provided in various types of accessories according to customer needs.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
