For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] For example, please refer to Figure 1-10 As shown:

[0039] A waterproof stage lamp comprises a lamp holder; a waterproof cavity 130 is arranged in the lamp holder; the waterproof cavity 130 is sealedly connected to a connecting seat 300, and a head threading hole 111 which penetrates the inside of the connecting seat 300 is arranged on the waterproof cavity 130; the other end of the connecting seat 300 is rotatably connected to an arm 200; the connecting seat 300 is rotatably connected to the arm 200 through a bearing 340, an oil seal 380 is arranged between the connecting seat 300 and the arm 200 to prevent rainwater from entering the arm wiring space 230, the connecting seat 300 and the waterproof cavity 130 are sealedly connected to prevent rainwater from entering the waterproof cavity 130 in the lamp holder, the electrical components in the waterproof cavity 130 enter the arm 200 through the internal wiring of the connecting seat 300, and then are electrically connected to the inside of the base from the lower end of the arm 200, so as to realize internal waterproof wiring.

[0040] In one embodiment of the present invention, a light emitting assembly is provided in the lamp holder, and the light emitting assembly is arranged in a waterproof cavity 130. The bottom of the waterproof cavity 130 is a metal bottom plate 110, and the top is sealed by a top cover 120 to form the waterproof cavity 130. A light-transmitting plate 121 is usually required to be provided in the middle of the top cover 120. The sealing structure between the top cover 120 and the metal bottom plate 110 can be waterproofed by a common sealing ring; the waterproofing between the light-transmitting plate 121 and the top cover 120 can be achieved by fixing and then gluing;

[0041] The metal bottom plate 110 is used to install the lamp board in the light output assembly for rapid heat conduction, and the head threading hole 111 is set on the metal bottom plate 110; a heat sink assembly is provided below the metal bottom plate 110, and the heat sink assembly is tightly connected to the metal bottom plate 110 to ensure rapid heat transfer;

[0042] In one embodiment, the radiator assembly is a plurality of heat dissipation fins welded under the metal base plate 110; in another embodiment, the radiator assembly includes a radiator base plate, and the radiator base plate has a plane opposite to the metal base plate 110, which can also ensure the heat dissipation effect after being fastened by screws.

[0043] In one embodiment of the present invention, the connection seat 300 includes a fixed connection portion 310 and a rotating connection portion 320; the fixed connection portion 310 is used to connect with the waterproof cavity 130, and the rotating connection portion 320 is used to be rotatably connected with the arm portion 200;

[0044] A wire hole 311 is provided at the top of the fixed connection part 310, and a wire routing hole 321 is provided at the middle of the rotating connection part 320. The wire hole 311 and the wire routing hole 321 are interconnected and used for routing. The size of the wire hole 311 is larger than the size of the head threading hole 111. The installation position of the wire hole 311 corresponds to the position of the head threading hole 111, and the head threading hole 111 is completely surrounded therein. A sealing ring accommodating groove 312 is provided on the periphery of the wire hole 311. A sealing ring 330 is provided in the sealing ring accommodating groove 312, and the sealing ring 330 is sealed and connected to the waterproof cavity 130;

[0045] In one embodiment, more specifically, it is fixedly connected to the metal bottom plate 110; the end surface provided with the wire hole 311 is provided with a plurality of threaded holes 313, and the fixed connection portion 310 is threadedly connected with the threaded holes 313 by screws to achieve fixed connection with the metal bottom plate 110;

[0046] The rotating connection part 320 is cylindrical in shape as a whole, and is hollow inside to form a wiring hole 321; the rotating connection part 320 is provided with a bearing mounting part 322 for mounting a bearing 340 and an oil seal mounting part 323 for mounting an oil seal 380; the outer ring of the bearing 340 is connected to the arm part 200, so that the head part and the arm part 200 can be rotatably connected; the oil seal 380 can effectively achieve waterproofing during the rotation process;

[0047] Preferably, the bearing mounting portion 322 is arranged at one end close to the fixed connection portion 310, and the oil seal mounting portion 323 is arranged at one end away from the fixed connection portion 310. A snap ring mounting groove 324 is formed in the middle of the bearing mounting portion 322 and the oil seal mounting portion 323 for mounting a snap ring 350, which can limit one side of the inner ring of the bearing 340; the other side of the inner ring of the bearing 340 can be limited by the end face of the fixed connection portion 310, or an annular boss 314 can be provided on the end face of the fixed connection portion 310 for limiting.

[0048] In one embodiment of the present invention, the arm 200 includes an end cover 210 and an arm metal cover plate 220, an arm wiring space 230 is formed inside the end cover 210 and the arm metal cover plate 220, and a docking hole 211 that is connected to the arm wiring space 230 is provided on the end cover 210; the docking hole 211 cooperates with the rotating connection part 320;

[0049] In order to further reduce the difficulty of installation and facilitate disassembly and maintenance, the docking hole 211 is connected to the oil seal installation part 323 through the oil seal 380; the outer periphery of the docking hole 211 is formed with a bearing seat installation groove 214, and the end cover 210 is connected to the outer ring of the bearing 340 through the bearing seat 360;

[0050] The bearing seat 360 includes a mounting portion 362 and a bearing matching portion 361. The inner surface of the bearing matching portion 361 is a bearing matching surface 363, which is used to match the outer ring of the bearing 340. The mounting portion 362 matches the bearing seat mounting groove 214. The end cover 210 is fixedly connected to the mounting portion 362 by a fixing screw 215 that penetrates the end cover 210. The bearing seat 360 can be easily disassembled by matching with the bearing 340.

[0051] The installation of the oil seal 380 is carried out separately from the installation of the bearing 340 to facilitate assembly and fixation. The oil seal 380 is first interference fit in the oil seal mating surface 212. The bearing 340 can be pre-installed in the bearing mounting portion 322, and the outer ring of the bearing 340 is then installed on the bearing seat 360. After the installation of the remaining components is completed, the assembly between the lamp holder and the arm 200 only requires the oil seal mounting portion 323 to be inserted into the oil seal 380. Since the oil seal mounting portion 323 and the oil seal 380 are also interference fit, the effectiveness of the seal can be guaranteed. If the oil seal mounting portion 323 cannot be easily and completely inserted into the oil seal 380, it can also be pre-positioned and the fixing screw 215 can be tightened to drive the bearing 340 using the bearing seat 360. The bearing 340 drives the rotating connection portion 320 through the retaining ring 350. After the fixing screw 215 is locked, the oil seal mounting portion 323 is also completely inserted into the oil seal 380 to complete the assembly.

[0052] The connection between the bearing seat 360 and the end cover 210 is the only fixed connection position between the lamp holder and the arm 200. When disassembling, it is only necessary to unscrew the fixing screw 215, and the remaining connection part of the oil seal 380 only needs to pull the arm 200 or the lamp holder to one side to complete the disassembly and separation of the two. It is simple and efficient.

[0053] In one embodiment of the present invention, compared with the previous embodiment, a step groove 365 is formed at the connection between the bearing matching portion 361 and the mounting portion 362, and the diameters of the two are different, and the diameter of the mounting portion 362 is larger. In the previous embodiment, the mounting portion 362 and the bearing matching portion 361 can be a barrel-shaped bearing seat 360 with a single inner diameter and outer diameter; in this embodiment, the step groove 365 is used to install a bearing baffle 370, which is used to limit the outer ring of the bearing 340, and a bearing baffle 364 can be provided on the inner side of the corresponding bearing matching surface 363 (the side away from the mounting portion 362), so as to limit the outer ring of the bearing 340 on both sides; one side of the bearing baffle 370 abuts against the step groove 365, and the other side abuts against the end cover 210;

[0054] The inner circle of the docking hole 211 is an oil seal mating surface 212, and an oil seal stopper 213 is provided on the oil seal mating surface 212 on one side close to the arm wiring space 230, for limiting the installation of the oil seal 380;

[0055] In one embodiment of the present invention, since the wiring harness enters the arm wiring space 230 through the wiring hole 321, due to the rotation requirement of the head, the wiring harness will rub against the rotating connection part 320. The rotating connection part 320 is usually a metal part, which is easy to cause wear to the wiring harness; by providing a wire protection ring installation groove 325 on the inner side of the oil seal installation part 323, and installing a wire protection ring 390 therein, the wear and damage to the wiring harness can be effectively reduced. The wire protection ring 390 is preferably made of plastic; a clearance groove 391 is provided on the side of the wire protection ring 390 close to the arm wiring space 230. The provision of the clearance groove 391 can ensure that the wiring harness has more sufficient space for movement and reduce the risk of wiring harness entanglement and friction.

[0056] The present invention mainly provides a waterproof connection structure between a stage lamp head and an arm 200 on one side. Since the waterproof cavity 130 of the head only needs to use the arm 200 on one side for wiring, the other side does not need to use a waterproof structure, thereby ensuring the waterproof effect of the head. A synchronous belt transmission structure is generally arranged between the other side of the head and the arm 200 to control the rotation of the lamp head 100. The electrical components of the synchronous belt transmission structure are arranged in the base, and waterproofing is achieved by the base structure. The related connection components exposed in the internal space of the arm 200 and the head do not need to be waterproofed, thereby simplifying the arrangement of the waterproof structure.

[0057] The synchronous belt transmission structure includes a synchronous belt 260, and each end of the synchronous belt 260 is matched with a synchronous belt pulley, a synchronous belt pulley is arranged at the end of the lamp holder 100, and a synchronous belt pulley 550 is connected to the transmission shaft 501, and the rotation of the transmission shaft 501 drives the lamp holder 100 to rotate;

[0058] like Figure 2 As shown, the waterproof principle of the lamp holder of the present invention is as follows: after rainwater enters from the gap between the end cover 210 and the metal bottom plate 110, the passage between the end cover 210 and the rotating connection part 320 is closed by the oil seal 380 on the left side, and the rainwater cannot enter the arm wiring space 230 through the through pipe; the passage into the wire hole 311 is closed by the sealing ring 330 on the right side, and the rainwater cannot enter the internal wiring space; a waterproof cavity 130 for installing the light emitting component is provided on the top of the lamp holder 100, and rainwater cannot enter the waterproof cavity 130, thereby damaging the light emitting component. Waterproofing is performed; the lower part of the arm wiring space 230 is connected to the interior of the base 400, and the base 400 is provided with a second wiring hole 401 connected to the arm wiring space 230. Since the arm 200 is fixed on the base 400, the waterproof sealing of the second wiring hole 401 can be achieved by a sealing ring, and the arm metal cover plate 220 is sealed with the end cover 210 to prevent external rainwater from entering the arm wiring space 230; since the synchronous belt drive structure is installed in the arm 200 on the other side, the waterproof structure can be omitted, thereby simplifying the installation and process difficulty.

[0059] In one embodiment of the present invention, the base 400 and the bottom cover 410 form a sealed housing, and the bottom cover 410 is sealedly connected to the base 400 through a sealing ring 330 to form an accommodation space inside the base 400; a waterproof motor is arranged in the accommodation space; a clearance hole 430 is arranged on one side wall of the base 400; a transmission shaft 501 of the waterproof motor extends out of the base 400 through the clearance hole 430;

[0060] The sealing end cover 530 is connected to the inner wall of the base 400 through the motor sealing ring 531; the motor sealing ring 531 is used to waterproof the clearance hole 430, so that the accommodating space is waterproofed under the action of the sealing ring 330 and the motor sealing ring 531;

[0061] The base 400 is an integrally formed housing without a bottom cover 410, and the internal space is approximately a rectangular parallelepiped. After the bottom cover 410 is fixedly connected, a relatively closed accommodation space is formed inside. On this basis, the clearance hole 430 provided on the base 400 is the only channel connected to the outside, and the channel is further sealed by the motor sealing ring 531, so that the waterproof structure design of the base 400 is easily realized.

[0062] In an embodiment of the present invention, arms 200 are fixedly connected to both sides of the base 400 , and the arms 200 are used to be rotatably connected to the lamp head assembly.

[0063] In one embodiment of the present invention, the base 400 is provided with a splicing assembly 440; the splicing assembly 440 includes a locking pin 443 movably arranged on the base 400; an adjusting pin 444 is connected to the locking pin 443; the locking pin 443 is controlled to move inward or outward by the adjusting pin 444;

[0064] The locking pin 443 is disposed in a slide groove 441 on the base 400; the slide groove 441 is formed by drilling a hole on the base 400, and the slide groove 441 does not pass into the accommodating space, thereby ensuring the waterproof effectiveness of the base 400;

[0065] The base 400 is provided with a long waist hole 442 which penetrates the slide groove 441, and the adjusting pin 444 is threadedly connected with the locking pin 443 through the long waist hole 442, so as to facilitate the installation and maintenance of the adjusting pin 444; a docking hole corresponding to the position of the locking pin 443 is provided on the other side of the base 400;

[0066] Two splicing components 440 are usually arranged on the same side. When multiple stage lights need to be connected, the locking pin 443 is pushed to the outside through the adjustment nail 444, and the locking pin 443 is inserted into the connecting hole on another stage light base 400 to achieve the splicing between multiple stage light bases 400.

[0067] In one embodiment of the present invention, arms 200 are provided on both sides of the base 400, and the lower ends of the arms 200 are fixedly connected to the base 400. The arm 200 on one side of the locking pin 443 is provided with a through hole 250 allowing the locking pin 443 to pass through, and the arm 200 on the other side is provided with a docking hole corresponding to the position of the locking pin 443.

[0068] In one embodiment of the present invention, a spring plunger 445 is provided on the base 400; the positioning bead of the spring plunger 445 cooperates with the locking pin 443 and can be used to control the push-pull damping of the locking pin 443. Two annular grooves 446 are provided on the locking pin 443, and the positioning of the locking pin 443 can be achieved by cooperating with the annular grooves 446 and the positioning column.
