[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Example 1

[0032] Combination Figures 1 to 4 As shown, the connection assembly of the present invention is schematically shown, including a mounting seat 10, a locking pin 20 and a shift block 30.

[0033] The locking pin 20 is slidably connected to the mounting base 10, so that the locking pin 20 can slide back and forth on the mounting base 10. When the locking pin 20 slides to one of the sliding stop points, the locking pin 20 is in a locked state, and when the locking pin 20 slides to the other sliding stop point, the locking pin 20 is in an unlocked state. When the locking pin 20 is in the locked state, its end can be inserted into a locking hole 61 to lock the light-emitting module 50 and the lamp body frame, so that the light-emitting module 50 and the lamp body frame can be detachably connected.

[0034] The shift block 30 is rotatably connected to the mounting base 10, and one end of the shift block 30 is movably connected to the locking pin 20. The installation and maintenance personnel can manually pull the shift block 30 to make the shift block 30 swing relative to the mounting base 10. The swinging shift block 30 then drives the locking pin 20 to slide relative to the mounting base 10, thereby driving the locking pin 20 to switch from a locked state to an unlocked state, or driving the locking pin 20 to switch from an unlocked state to a locked state.

[0035] Therefore, the installation and maintenance personnel can switch the locking state and unlocking state of the lock pin 20 without using any tools, realizing tool-free disassembly and assembly of the light-emitting module 50. At the same time, the above structure is relatively simple and convenient for large-scale batch production, which helps to reduce the production and purchase unit prices of various materials and improve product competitiveness.

[0036] In this embodiment, if Figure 2 and Figure 3 The connection assembly further includes an elastic member 40, which is preferably a coil spring. The two ends of the elastic member 40 are respectively connected to the lock pin 20 and the mounting seat 10, wherein the elastic member 40 is sleeved on the lock pin 20. The installation and maintenance personnel pull the shift block 30 to make the shift block 30 swing forward relative to the mounting seat 10, drive the lock pin 20 to slide relative to the mounting seat 10, and the lock pin 20 switches from the locked state to the unlocked state. At this time, the elastic member 40 is compressed by the sliding lock pin 20. When the installation and maintenance personnel stop applying force to the shift block 30, the elastic member 40 restores its deformation and pushes the lock pin 20 to slide relative to the mounting seat 10. The lock pin 20 switches from the unlocked state to the locked state, and the lock pin 20 drives the shift block 30 to swing in the opposite direction relative to the mounting seat 10 to reset.

[0037] Furthermore, the lock pin 20 is provided with a slider 21, which is arranged on the outer wall surface of the lock pin 20, and extends in the normal direction of the axis of the lock pin 20. The slider 21 is detachably connected to the outer wall surface of the lock pin 20, and the two are connected by threads to facilitate the disassembly and assembly of the slider 21 and the lock pin 20. The end of the shift block 30 is provided with a transmission slot 321. In this embodiment, one end of the transmission slot 321 passes through the end of the shift block 30, so that the transmission slot 321 is a U-shaped hole, and the slider 21 is slidably embedded in the transmission slot 321.

[0038] When the shift block 30 swings relative to the mounting seat 10, the inner wall surface of the transmission slot 321 abuts against and pushes the slider 21 to move, forcing the lock pin 20 to slide relative to the mounting seat 10. At the same time, the slider 21 slides in the transmission slot 321 to prevent the slider 21 and the shift block 30 from interfering with each other and preventing the lock pin 20 from sliding relative to the mounting seat 10. The cross section of the slider 21 is circular, which makes the slider 21 a cylindrical structure, which is conducive to the slider 21 sliding back and forth in the transmission slot 321 while allowing the slider 21 to rotate relative to the transmission slot 321, so that the transmission movement between the slider 21 and the transmission slot 321 is smoother.

[0039] In order to prevent the locking pin 20 from rotating about its axis relative to the mounting seat 10, Figure 2 and Figure 4 As shown, the mounting seat 10 is provided with a guide slot 13, which is parallel to the sliding direction of the lock pin 20, and the slider 21 is slidably arranged in the guide slot 13. The inner wall surface of the guide slot 13 limits the movement direction of the slider 21, which can prevent the lock pin 20 from rotating around its axis relative to the mounting seat 10. In this embodiment, the lock pin 20, the guide slot 13 and the transmission slot 321 are arranged in sequence.

[0040] The paddle block 30 includes a paddle 31 and a transmission arm 32 connected to each other. The paddle 31 and the transmission arm 32 extend in opposite directions. The paddle 31, the transmission arm 32 or the connection between the two are rotatably connected to the mounting seat 10. In this embodiment, the paddle 31 is rotatably connected to the mounting seat 10. The end of the transmission arm 32 is provided with a transmission slot 321. The installation and maintenance personnel can use their fingers to pull the paddle 31 to make the paddle block 30 swing relative to the mounting seat 10. In order to prevent the paddle 31 and the installation and maintenance personnel's fingers from accidentally sliding and detaching, a bending portion 311 is provided at one end of the paddle 31 away from the transmission arm 32. The bending portion 311 is inclined with the paddle 31. The installation and maintenance personnel's fingers are respectively attached to the paddle 31 and the bending portion 311. The bending portion 311 can effectively prevent the fingers and the paddle 31 from sliding relative to each other.

[0041] Example 2

[0042] like Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the mounting seat 10 is provided with a accommodating cavity 11 and an opening 12 connected to the accommodating cavity 11, the cross section of the accommodating cavity 11 is circular, the cross section of the opening 12 is also circular, a cylindrical locking pin 20 is slidably arranged in the accommodating cavity 11, and the end of the locking pin 20 can pass through or retract into the opening 12. When the locking pin 20 is in a locked state, the end of the locking pin 20 passes through the above-mentioned opening 12, and when the locking pin 20 is in an unlocked state, the end of the locking pin 20 retracts into the above-mentioned opening 12.

[0043] Among them, the cross-sectional area of ​​the accommodating cavity 11 is larger than the cross-sectional area of ​​the opening 12, that is, the aperture of the accommodating cavity 11 is larger than the aperture of the opening 12, and the locking pin 20 includes a transmission section 22 and a locking section 23 arranged in sequence along its axial direction, and the cross-sectional area of ​​the transmission section 22 is larger than the cross-sectional area of ​​the locking section 23, that is, the diameter of the transmission section 22 is larger than the diameter of the locking section 23, and the cross-sectional area of ​​the transmission section 22 is larger than the cross-sectional area of ​​the opening 12, so that the opening 12 can prevent the transmission section 22 from passing through the opening 12, and the transmission section 22 can be slidably arranged in the accommodating cavity 11, and the locking section 23 can be slidably arranged in the opening 12, and only the locking section 23 can pass through or retract into the opening 12.

[0044] Example 3

[0045] like Figure 5 The utility model provides a lamp, including a lamp body frame 60, a light emitting module 50 and the connection assembly as described above, wherein a mounting seat 10 is arranged on the light emitting module 50, a plurality of light emitting chips are arranged on the light emitting module 50, a locking hole 61 is provided on the lamp body frame 60, and a locking pin 20 is detachably inserted into the locking hole 61. Specifically, when the locking pin 20 is in a locked state, the end of the locking pin 20 is inserted into the locking hole 61 to connect the light emitting module 50 with the lamp body frame 60. When the locking pin 20 is in an unlocked state, the end of the locking pin 20 is separated from the locking hole 61, and the installation and maintenance personnel can separate the light emitting module 50 from the lamp body frame 60, thereby realizing tool-free disassembly and assembly of the light emitting module 50.

[0046] To summarize, the locking pin 20 can slide on the mounting base 10 to switch the locking state and the unlocking state of the locking pin 20. The shift block 30 is rotatably connected to the mounting base 10, and one end of the shift block 30 is movably connected to the locking pin 20. The installation and maintenance personnel can manually shift the shift block 30 to make it swing relative to the mounting base 10, which can drive the locking pin 20 to switch from the locked state to the unlocked state, or from the unlocked state to the locked state. The locking pin 20 can lock the light-emitting module 50 of the lamp on the lamp body frame of the lamp, thereby realizing tool-free disassembly and assembly of the light-emitting module 50.
