[0034] Example 1

[0035] Combination Figures 1 to 8As shown, the housing quick-release structure of the utility model is schematically shown, including a locking pin 30, a driving mechanism 40, a first mounting seat 10 and a second mounting seat 20. The first mounting seat 10 is provided with a locking hole 11, and the locking hole 11 is preferably a through hole. The driving mechanism 40 and the locking pin 30 are both provided on the second mounting seat 20, wherein the locking pin 30 can be slidably connected to the second mounting seat 20 along its axial direction, and the driving mechanism 40 is connected to the locking pin 30.

[0036] The driving mechanism 40 drives the locking pin 30 to penetrate into or disengage from the locking hole 11 when the first mounting seat 10 and the second mounting seat 20 rotate relative to each other. For example, when the second mounting seat 20 rotates forwardly relative to the first mounting seat 10, the driving mechanism 40 drives the locking pin 30 to penetrate into the locking hole 11. Therefore, the first mounting seat 10 and the second mounting seat 20 are connected by rotation around the axis of the locking pin 30, that is, the first mounting seat 10 and the second mounting seat 20 are connected by the locking pin 30 and the locking hole 11. When the second mounting seat 20 rotates reversely relative to the first mounting seat 10, the driving mechanism 40 drives the locking pin 30 to disengage from the locking hole 11, and the first mounting seat 10 and the second mounting seat 20 are separated from each other, thereby realizing the quick release of the first mounting seat 10 and the second mounting seat 20.

[0037] Specifically, combined Figure 2 and Figure 4 As shown, the driving mechanism 40 includes a cam 41 and a transmission member 42, and the cam 41 and the transmission member 42 are movably connected. One of the cam 41 and the transmission member 42 is arranged on the locking pin 30, and the other is detachably connected to the first mounting seat 10. Therefore, by applying force to force the first mounting seat 10 and the second mounting seat 20 to rotate relative to each other, the cam 41 and the transmission member 42 can rotate relative to each other, and then the locking pin 30 can slide relative to the second mounting seat 20 and penetrate into or escape from the locking hole 11. In this embodiment, the cam 41 is an end face cam 41, and the end of the transmission member 42 can slidably abut against the end face of the end face cam 41. The cam 41 is arranged on the locking pin 30, and the transmission member 42 is detachably connected to the first mounting seat 10.

[0038] In order to drive the locking pin 30 to reset, the driving mechanism 40 includes an elastic member 43, the two ends of which are respectively connected to the locking pin 30 and the second mounting seat 20. The locking pin 30 is driven by the cam 41 and the transmission member 42 to penetrate into the locking hole 11. At this time, the elastic member 43 is compressed, and the locking pin 30 can be separated from the locking hole 11 under the elastic force of the elastic member 43.

[0039] Combination Figure 3 and Figure 4In order to realize the detachable connection between the driving mechanism 40 and the first mounting seat 10, the driving mechanism 40 includes a rotation limit block 44, and the transmission member 42 is provided with the rotation limit block 44. One side of the rotation limit block 44 is provided with a first rotation limit plane 441. The first mounting seat 10 is provided with a rotation limit groove 12. The inner wall surface of the rotation limit groove 12 is provided with a second rotation limit plane 121. The rotation limit block 44 is detachably connected to the rotation limit groove 12. The first rotation limit plane 441 and the second rotation limit plane 121 are in contact with each other, so the rotation limit block 44 and the rotation limit groove 12 cannot rotate relative to each other. Since the cross-section of the rotation limit groove 12 is U-shaped, that is, one side of the rotation limit groove 12 is provided with an opening, the rotation limit block 44 can be embedded in or detached from the rotation limit groove 12 through the opening to realize the detachable connection between the transmission member 42 and the first mounting seat 10.

[0040] Furthermore, a cylindrical sleeve 21 is provided on the second mounting seat 20. Figure 5 and Figure 6 The elastic member 43, the cam 41 and the transmission member 42 are all located in the sleeve 21. One end of the locking pin 30 is located in the sleeve 21. The other end of the locking pin 30 can extend out of the sleeve 21 or retract into the sleeve 21 under the drive of the driving mechanism 40. When the end of the locking pin 30 extends out of the sleeve 21, the locking pin 30 penetrates the locking hole 11. When the end of the locking pin 30 retracts into the sleeve 21, the locking pin 30 and the locking hole 11 are separated from each other. The sleeve 21 can be used to install the locking pin 30, the transmission member 42 and the cam 41, and provide protection. Figure 7 and Figure 8 The inner wall surface of the sleeve 21 is provided with a guide groove 211 parallel to its axis, and the outer wall surface of the cam 41 is provided with a guide block 411, which is slidably embedded in the guide groove 211. The guide groove 211 and the guide block 411 work together to prevent the cam 41 from rotating relative to the sleeve 21, and only allow the cam 41 to slide relative to the sleeve 21 along the axial direction of the sleeve 21.

[0041] Preferably, a supporting groove 13 is provided on the first mounting seat 10 , the cross section of the supporting groove 13 is U-shaped, and the sleeve 21 is rotatably embedded in the supporting groove 13 .

[0042] Example 2

[0043] The difference between this embodiment and the first embodiment is that there are multiple locking holes 11, locking pins 30 and driving mechanisms 40, and each locking pin 30 corresponds to a driving mechanism 40 and a locking hole 11. At least two locking pins 30 are arranged opposite to each other, and the locking pins 30 are defined to have a locked state and an unlocked state. When the locking pin 30 is in the locked state, the locking pin 30 penetrates the locking hole 11, and when the locking pin 30 is in the unlocked state, the locking pin 30 is separated from the locking hole 11. The two locking pins 30 arranged opposite to each other move opposite to each other during the process of switching from the unlocked state to the locked state.

[0044] In this embodiment, the number of the locking pins 30 is two.

[0045] Example 3

[0046] In order to solve the same technical problem, this embodiment discloses a lamp, including an upper shell, a lower shell and the shell quick-release structure as described above, wherein the first mounting seat 10 is fixedly disposed on the upper shell, and the second mounting seat 20 is fixedly disposed on the lower shell.

[0047] To summarize, the driving mechanism 40 and the locking pin 30 are both arranged on the second mounting seat 20, and the driving mechanism 40 is connected to the locking pin 30. The driving mechanism 40 drives the locking pin 30 to penetrate into or disengage from the locking hole 11 when the first mounting seat 10 and the second mounting seat 20 rotate relative to each other. When the locking pin 30 penetrates into the locking hole 11, the first mounting seat 10 and the second mounting seat 20 are rotationally connected around the axis of the locking pin 30. When the locking pin 30 disengages from the locking hole 11, the first mounting seat 10 and the second mounting seat 20 can be separated from each other to achieve quick release of the two.

[0048] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
