DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0034] like Figures 1 to 11 As shown, the explosion-proof lamp which is easy to install described in this embodiment includes a mounting seat 10 and a lamp body 20; U-shaped seats 11 and locking structures are installed at both ends of the mounting seat 10, and the locking structure is provided with a transmission groove 1221;

[0035] The lamp body portion 20 includes a lamp tube 21 and plugs 22 rotatably installed at both ends of the lamp tube 21, each plug 22 is fixedly installed with an end cover 23, a mounting shaft 231 is convexly provided at the center of the end cover 23, a transmission shaft 24 is movably inserted into the mounting shaft 231, and a one-way transmission mechanism is provided between the transmission shaft 24 and the end of the lamp tube 21; when the lamp tube 21 is rotated, a thrust is transmitted to the transmission shaft 24 through the one-way transmission mechanism, so that the transmission shaft 24 extends to cooperate with the transmission groove 1221, thereby utilizing the transmission shaft 24 to cooperate with the transmission groove 1221 to transmit a rotational torque to the locking structure, so that the locking structure can unlock the mounting shaft 231 located in the U-shaped seat 11.

[0036] Specifically, when installing the explosion-proof lamp of this embodiment, the mounting seat 10 is fixedly installed on the external mounting position, and then the mounting shafts 231 at both ends of the lamp body 20 are respectively inserted into the U-shaped seat 11, so as to use the U-shaped seat 11 to limit the rotational freedom of the end cover 23. At this time, the transmission shaft 24 corresponds to the position of the transmission groove 1221, and then a rotational torque is applied to the lamp tube 21 in a clockwise manner. The lamp tube 21 transmits a thrust to the transmission shaft 24 through the one-way transmission mechanism, so that the transmission shaft 24 extends outward and is inserted into the transmission groove 1221. The mounting shaft 231 in the U-shaped seat 11 is locked by the locking structure, and the locking structure is locked. The locking structure locks the mounting shaft 231 in the U-shaped seat 11, and prevents the mounting shaft 231 from being separated from the U-shaped seat 11. After the locking structure is locked, the driving shaft 24 is removed from the driving groove 1221, and the installation of the lamp body 20 is completed.

[0037] When the lamp body 20 needs to be disassembled or the lamp body 20 needs to be held in hand for use, a rotational torque is applied clockwise to the lamp tube 21, and a thrust is applied to the transmission shaft 24 through the one-way transmission mechanism, so that the transmission shaft 24 is inserted into the transmission groove 1221, thereby realizing power transmission between the lamp tube 21 and the locking structure. Then, the lamp tube 21 is continued to be rotated so that the locking structure releases the lock on the installation shaft 231, and then the rotational torque on the lamp tube 21 is released, and the transmission shaft 24 is removed from the transmission groove 1221. At this time, the lamp body 20 can be removed from the mounting base 10.

[0038] In this embodiment, a U-shaped seat 11 and a locking structure are set on the mounting seat 10, and a transmission shaft 24 and a one-way transmission mechanism are set on the lamp body 20, so that the rotational torque transmission between the lamp body 20 and the locking structure is realized by utilizing the cooperation between the transmission shaft 24 and the transmission groove 1221, so that the installation and disassembly of the lamp body 20 can be realized by rotating the lamp tube 21, the disassembly and assembly are convenient, the structure is more flexible to use, and the scene adaptability is better.

[0039] like Figures 9 to 11 As shown, the explosion-proof lamp described in this embodiment is easy to install. In some embodiments, the one-way transmission mechanism includes a one-way seat 251 rotatably installed on the plug 22, a driving shaft 252 installed on one side of the one-way seat 251, a one-way ratchet 253 rotatably connected to the other side of the one-way seat 251, and an elastic pawl 254 arranged on the other side of the one-way seat 251; the shaft neck of the one-way ratchet 253 is fixedly connected to the end of the lamp tube 21; the elastic pawl 254 is unidirectionally meshed with the one-way ratchet 253; one end of the transmission shaft 24 movably extends into the driving shaft 252 and is transmission-connected to the driving shaft 252, so that the transmission shaft 24 moves axially under the drive of the driving shaft 252.

[0040] Specifically, when installing the lamp body 20, the installation shafts 231 at both ends of the lamp body 20 are respectively inserted into the U-shaped seat 11, and then a rotational torque is applied to the lamp tube 21 in a clockwise manner. The lamp tube 21 drives the one-way ratchet 253 to rotate, and the one-way ratchet 253 drives the one-way seat 251 to rotate through the elastic pawl 254. The one-way seat 251 drives the driving shaft 252 to rotate, and the driving shaft 252 drives the transmission shaft 24 to extend out of the installation shaft 231 and insert into the transmission groove 1221, thereby realizing power transmission between the lamp tube 21 and the locking structure. When the rotational torque continues to be applied to the lamp tube 21 in a clockwise manner, the driving shaft 252 drives the transmission shaft 24 to rotate, and the transmission shaft 24 drives the locking structure through the transmission groove 1221 to lock the installation seat 10 located in the U-shaped seat 11 to prevent the installation shaft 231 from detaching from the U-shaped seat 11.

[0041] like Fig. 9 and Fig.11 As shown, in some embodiments of the explosion-proof lamp described in this embodiment, the inner wall of the driving shaft 252 is provided with a spiral groove 2521, and the outer wall of the transmission shaft 24 is provided with a bayonet 241, and the bayonet 241 is movably embedded in the spiral groove 2521. Specifically, when the driving shaft 252 rotates, the driving shaft 252 cooperates with the spiral groove 2521 and the bayonet 241, thereby applying a thrust to the transmission shaft 24, so that the transmission shaft 24 is inserted into the transmission groove 1221. At this time, the bayonet 241 abuts against the end of the spiral groove 2521. At this time, when the lamp tube 21 continues to rotate, the driving shaft 252 drives the transmission shaft 24 to rotate through the bayonet 241, thereby transmitting a rotational torque to the locking structure through the transmission shaft 24, so that the locking structure locks the installation shaft 231.

[0042] like Fig. 9 As shown, in some embodiments of the explosion-proof lamp that is easy to install, the outer wall of the transmission shaft 24 has a first profile, and the groove wall of the transmission groove 1221 has a second profile that can match the first profile. In this embodiment, by providing the first profile and the second profile, when the transmission shaft 24 is inserted into the transmission groove 1221, the first profile matches the second profile, thereby realizing the transmission of the rotational torque to the locking structure.

[0043] like Figures 9 to 11As shown, in some embodiments of the explosion-proof lamp described in this embodiment, a torsion spring 27 is connected between the drive shaft 252 and the end cover 23. In this embodiment, the torsion spring 27 is provided, so that when the drive shaft 252 rotates relative to the end cover 23, the torsion spring 27 stores energy until the drive shaft 252 cooperates with the drive shaft 24 through the spiral groove 2521 and the bayonet 241 to insert into the transmission groove 1221; when the rotational torque continues to be applied to the lamp tube 21, the drive shaft 252 drives the transmission shaft 24 to rotate, so that the locking structure locks the installation shaft 231, and the torsion spring 27 continues to store energy. After the locking structure completes the locking, the rotational torque on the lamp tube 21 is released, and at this time, the torsion spring 27 releases the stored energy, and the torsion spring 27 drives the drive shaft 25 2 counterclockwise rotation, the driving shaft 252 drives the one-way seat 251 to rotate counterclockwise, and since the elastic pawl 254 is unidirectionally meshed with the one-way ratchet 253, the one-way seat 251 will not drive the one-way ratchet 253 to rotate through the elastic pawl 254, that is, the one-way seat 251 is idle at this time, and the counterclockwise rotation of the driving shaft 252 will drive the transmission shaft 24 to move inward through the spiral groove 2521 and the bayonet 241, so that the transmission shaft 24 moves out of the transmission groove 1221, cuts off the power transmission between the transmission shaft 24 and the locking structure, and realizes the reset of the transmission shaft 24;

[0044] When it is necessary to remove the lamp body 20, a rotational torque is applied to the lamp tube 21 in a clockwise manner so that the transmission shaft 24 is inserted into the transmission groove 1221 again, so that the locking structure releases the lock on the installation shaft 231. After unlocking, the transmission shaft 24 is reset under the action of the torsion spring 27, and the lamp body 20 can be removed from the mounting base 10.

[0045] like Figure 8 and Fig. 9 As shown, the present embodiment describes an explosion-proof lamp that is easy to install. In some embodiments, a friction sleeve 26 coaxially arranged with the transmission shaft 24 is installed in the installation shaft 231, and the inner wall of the friction sleeve 26 is provided with a third surface that matches the first surface, and the outer wall of the friction sleeve 26 rotates and frictionally matches with the inner wall of the installation shaft 231; the friction force between the friction sleeve 26 and the installation shaft 231 is greater than the rotational torque applied to the transmission shaft 24 when the drive shaft 252 rotates relative to the transmission shaft 24.

[0046] Specifically, the friction sleeve 26 is provided in this embodiment, so as to utilize the friction force between the friction sleeve 26 and the end cover 23 to limit the rotational freedom of the transmission shaft 24 when the transmission shaft 24 is extended, so as to prevent the rotational torque applied by the drive shaft 252 on the transmission shaft 24 through the spiral groove 2521 and the bayonet 241 from driving the transmission shaft 24 to rotate, thereby ensuring that the transmission shaft 24 is reliably inserted into the transmission groove 1221; when the bayonet 241 abuts against the end of the spiral groove 2521, the drive shaft 252 drives the transmission shaft 24 to rotate, and the transmission shaft 24 drives the friction sleeve 26 to rotate relative to the end cover 23 to overcome the friction force, so as to realize the unlocking and locking of the locking structure;

[0047] When the torsion spring 27 releases the stored energy, the drive shaft 252 cooperates with the spiral groove 2521 and the bayonet 241 to apply an inward thrust to the transmission shaft 24, causing the transmission shaft 24 to retract. At this time, the friction between the friction sleeve 26 and the end cover 23 prevents the transmission shaft 24 from rotating, thereby ensuring that the transmission shaft 24 retracts to cut off the power transmission between the transmission shaft 24 and the locking structure.

[0048] like Figure 4 and Figure 7 As shown, in some embodiments of the explosion-proof lamp that is easy to install, the installation shaft 231 has a fourth profile. When the installation shaft 231 is inserted into the U-shaped seat 11, the fourth profile cooperates with the inner wall of the U-shaped seat 11 to limit the rotational freedom of the installation shaft 231. In this embodiment, by setting the fourth profile, the inner wall of the U-shaped seat 11 cooperates with the fourth profile to limit the rotational freedom of the installation shaft 231, so as to reliably rotate the lamp tube 21 relative to the plug 22 and the end cover 23.

[0049] like Figures 9 to 11 As shown, in some embodiments, the one-way seat 251 is provided with a receiving groove on the other side, the one-way ratchet 253 is rotatably connected in the receiving groove, and the elastic pawl 254 is provided on the groove wall of the receiving groove. By providing the receiving groove, the structure of this embodiment is more compact.

[0050] like Figures 3 to 5As shown, the explosion-proof lamp described in this embodiment is easy to install. In some embodiments, the locking structure includes a locking seat 121 fixedly arranged on the mounting seat 10 and a driving disk 122 rotatably connected to the locking seat 121; the locking seat 121 is symmetrically provided with connecting arms 1211 located in the same radial direction, and the two connecting arms 1211 are slidably connected with a transmission member 123, and the transmission member 123 is in the shape of an L-shaped rod; a transmission groove 1221 is arranged at the center of the driving disk 122, and the driving disk 122 is provided with two driving grooves 1222, and the driving grooves 1222 are in the shape of a vortex line; The U-shaped seat 11 is fixedly connected to the two connecting arms 1211; a volute spring 124 is connected between the driving disk 122 and the locking seat 121; one end of the two transmission members 123 is movably embedded in the corresponding driving groove 1222, and the other end of one of the transmission members 123 is connected to an elastic claw 125, which movably passes through one end of the U-shaped seat 11, and the other transmission member 123 is connected to a locking slider 126, which movably passes through the other end of the U-shaped seat 11, and a locking track for cooperating with the elastic claw 125 is provided on the surface of the locking slider 126.

[0051] Specifically, when the transmission shaft 24 is inserted into the transmission groove 1221, as the lamp tube 21 continues to rotate clockwise, the transmission shaft 24 drives the driving disk 122 to rotate, so that the spiral spring 124 stores energy. At this time, the driving disk 122 pushes the two transmission members 123 to move toward each other through the driving groove 1222, and the two transmission members 123 drive the elastic claw 125 and the locking slider 126 to move toward each other until the elastic claw 125 is locked with the locking track, so that the spiral spring 124 is kept in the energy storage state, thereby locking the installation shaft 231;

[0052] When it is necessary to remove the lamp body part 20, the lamp tube 21 is rotated clockwise, and the transmission shaft 24 is inserted into the transmission groove 1221, driving the driving disk 122 to rotate. The driving disk 122 cooperates with the driving groove 1222 and the transmission member 123, so that the elastic claw 125 is unlocked from the locking track. At this time, the spiral spring 124 releases the stored energy, so that the driving disk 122 rotates in the opposite direction. The driving disk 122 drives the elastic claw 125 and the locking slider 126 to move away from each other through the driving groove 1222 and the transmission member 123, thereby releasing the lock on the installation shaft 231. At this time, the lamp body part 20 can be removed from the mounting base 10.

[0053] like Figure 6As shown, the explosion-proof lamp that is easy to install described in this embodiment, in some embodiments, the locking track includes a first horizontal section 1261, a first inclined section 1262, a second horizontal section 1263, a second inclined section 1264, a third inclined section 1265, a third horizontal section 1266 and a fourth inclined section 1267 that are connected in sequence; the end of the first horizontal section 1261 away from the first inclined section 1262 passes through the locking slider 126, and the fourth inclined section 1267 is connected to the end of the first horizontal section 1261 close to the first inclined section 1262; the connection between the second inclined section 1264 and the third inclined section 1265 forms a locking position, the connection between the third inclined section 1265 and the third horizontal section 1266 is provided with a first transition step 1268, and the connection between the fourth inclined section 1267 and the first horizontal section 1261 is provided with a second transition step 1269.

[0054] Specifically, one end of the first horizontal section 1261 passes through the locking slider 126 so that the elastic claw 125 enters the first horizontal section 1261, one end of the first inclined section 1262 is connected to the other end of the first horizontal section 1261, one end of the second horizontal section 1263 is connected to the other end of the first inclined section 1262, one end of the second inclined section 1264 is connected to the other end of the second horizontal section 1263, one end of the third inclined section 1265 is connected to the other end of the second inclined section 1264, one end of the third horizontal section 1266 is connected to the other end of the third inclined section 1265, one end of the fourth inclined section 1267 is connected to the other end of the third horizontal section 1266, and the other end of the fourth inclined section 1267 is connected to the other end of the first horizontal section 1261. The locking position is located at a side of the first horizontal section 1261 close to the second horizontal section 1263.

[0055] When the driving disc 122 drives the two transmission members 123 to move toward each other, the elastic claw 125 penetrates into the U-shaped seat 11, the locking slider 126 penetrates into the U-shaped seat 11, and the end of the elastic claw 125 enters the first horizontal section 1261 and moves along the first horizontal section 1261. After being blocked by the second transition step 1269, it enters the first inclined section 1262, enters the second horizontal section 1263 through the first inclined section 1262, and then moves along the second horizontal section 1263 until the end of the elastic claw 125 abuts against the second When the end of the horizontal section 1263 is reached, the rotation of the lamp tube 21 is released. At this time, the spiral spring 124 drives the driving disk 122 to rotate in the opposite direction, so that the end of the elastic claw 125 enters the second inclined section 1264 from the second horizontal section 1263 under its own elastic action, and the end of the elastic claw 125 moves along the second inclined section 1264 until the end of the elastic claw 125 enters the locking position. At this time, the elastic claw 125 is locked with the locking track, and the spiral spring 124 stops releasing the stored energy, thereby achieving the locking of the installation shaft 231;

[0056] When the lamp body 20 needs to be removed, a clockwise rotation torque is applied to the lamp tube 21, so that the transmission shaft 24 drives the driving disk 122 to rotate, so that the two transmission members 123 move toward each other. At this time, the end of the elastic claw 125 moves from the locking position along the third inclined section 1265 under its own elastic action, and passes through the first transition step 1268 and enters the third horizontal section 1266 until the end of the elastic claw 125 abuts against the end of the third horizontal section 1266, and then releases the rotation force on the lamp tube 21. Moment, at this time, the spiral spring 124 releases the stored energy, driving the driving disk 122 to rotate in the opposite direction, and the driving disk 122 drives the elastic claw 125 and the locking slider 126 to move away from each other. At this time, the end of the elastic claw 125 moves along the third horizontal section 1266, and then enters the fourth inclined section 1267 from the third horizontal section 1266 until it crosses the second transition step 1269 and returns to the first horizontal section 1261, and then moves out of the first horizontal section 1261, thereby releasing the lock on the mounting shaft 231.

[0057] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
