Description

[0002] The connecting shaft structure between the arm and the lamp body of the outdoor stage lamp should play four conventional roles: connecting and fixing the arm and the lamp body, allowing the lamp body to rotate around the arm, allowing the arm to support the lamp body, and connecting the wiring harness between the arm and the lamp body.

[0003] Since the connecting shaft needs to be both rotatable and waterproof and dustproof, the structural coordination of the connecting shaft is very high, which increases the difficulty of the installation and use of the structure. When installing the connecting shaft, the installation coordination of the lamp body and the connecting shaft, the arm and the connecting shaft must extend into each other's bodies, so as to ensure the safe connection of the lamp body and the arm and the safe use of the lamp. If the lamp body and the connecting shaft, the arm and the connecting shaft are only flat and fit together at the end faces and fixed with screws without extending into each other's bodies, the screws will easily loosen and the sealing will be poor. Such a structure cannot meet the waterproof and dustproof safety requirements of outdoor lamps.

[0046] In some embodiments of the present application, the first rotating part is a rotating shaft, and the second rotating part is a shaft sleeve. In other embodiments, the first rotating part is a shaft sleeve, and the second rotating part is a rotating shaft.

[0047] In some embodiments of the present application, a first sealing gasket 330 is provided between the first rotating shaft 310 and the lamp body assembly 100, and a second sealing gasket 340 is provided between the first shaft sleeve 320 and the first end 210; it is understood that the provision of the sealing gasket can prevent external moisture or dust from entering the inner cavity of the lamp body from the end surface where the lamp body and the rotating shaft are connected; the connecting screw holes of the lamp body and the rotating shaft are all provided within the sealing range of the sealing gasket. In some embodiments of the present application, a third sealing gasket 430 is provided between the second rotating shaft 410 and the lamp body assembly 100, and a fourth sealing gasket 440 is provided between the second shaft sleeve 420 and the second end 220; it is understood that the provision of the sealing gasket can prevent external moisture or dust from entering the inner cavity of the arm from the end surface where the shaft sleeve and the arm are connected, and the connecting screw holes of the shaft sleeve and the arm are all provided within the sealing range of the sealing gasket.

[0048] In some embodiments of the present application, a first bearing 350 is provided between the first sleeve 320 and the first rotating shaft 310, and a second bearing 450 is provided between the second sleeve 420 and the second rotating shaft 410. The bearing is provided in the sleeve, and the rotating shaft is passed through the bearing, thereby ensuring the transmission accuracy and making the installation cooperation between the lamp body and the connecting shaft, and the arm and the connecting shaft extend into each other, ensuring the safe connection between the lamp body and the arm and the safe use of the lamp. In some embodiments,

[0049] In some embodiments of the present application, a first skeleton oil seal 360 is provided between the first rotating shaft 310 and the lamp body assembly 100, and a second skeleton oil seal 460 is provided between the first sleeve 320 and the first end 210. The provision of the skeleton oil seal can further improve the waterproof and dustproof effect. In some embodiments, an axis clamp 370 for limiting the first bearing 350 is provided between the first sleeve 320 and the first rotating shaft 310, and a washer 380 is provided between the axis clamp 370 and the first bearing 350. The axis clamp 370 is used to ensure the installation accuracy of the bearing. In some embodiments, an axis lock limit plate 470 for limiting the axial position is provided on the second rotating shaft 410. The axis lock limit plate 470 cooperates with the boss of the sleeve to limit the axial position of the second rotating shaft 410 so that it is correctly installed in a specific position.

[0050] In some embodiments of the present application, a transmission member 510 for driving the lamp body assembly 100 to rotate is provided on the outer side of one of the first rotating parts, and a lamp body rotation limiting plate 520 for limiting the lamp body assembly 100 is provided on the second rotating part. It can be understood that the transmission member 510 is used to connect with the driving member so that the lamp body assembly 100 can swing under the drive of the driving member. The lamp body rotation limiting plate 520 is used to limit the swing range of the lamp body assembly 100 and determine the adjustment stroke for normal use.

[0051] In some embodiments, the transmission member 510 is a rotating pulley, and the lamp body assembly 100 is driven by belt transmission. In other embodiments, the transmission member 510 can also be configured to include but not limited to a crank rocker mechanism, a guide rail slider mechanism, a gear transmission mechanism, etc., which will not be described in detail here.

[0052] In some embodiments of the present application, each second rotating part is provided with a wire tie plate 530 for fixing the wire harness, and a wire protection sleeve 540 for protecting the wire harness is provided on the wire tie plate 530. It can be understood that the wire harness can be fixed to the wire tie plate 530 with a cable tie after passing through the left and right shaft holes. Since the wire tie plate 530 is fixed to the arm assembly 200 and does not rotate with the lamp body, and under the protection of the wire protection sleeve 540, it can effectively prevent the wire harness from being damaged by friction with the inner holes of the right shaft and the left shaft.

[0053] In some embodiments, the right shaft assembly is composed of a bearing, a right shaft sleeve, a right shaft sealing gasket, a skeleton oil seal, a shaft lock limit plate 470, and a right shaft; the right shaft assembly is assembled as follows: first, the shaft lock limit plate 470 is inserted from the right end of the right shaft, and after it fits with the right large-diameter end face of the right shaft, the shaft lock limit plate 470 is fixed to the right large-diameter end face of the right shaft with screws; then the shaft sealing gasket is put into the contoured groove on the left end face of the right shaft sleeve and pressed to the bottom; then the shaft is Press the bearing into the stepped hole at the right end of the right-turn shaft sleeve and press it into place with the end faces flush; press the skeleton oil seal into the stepped hole at the left end of the right-turn shaft sleeve, with the open end of the skeleton oil seal facing right, until the open end face fits with the end face of the stepped hole at the right end of the right-turn shaft sleeve; insert the right shaft equipped with the shaft lock limit plate 470 into the right-turn shaft sleeve from the end equipped with the skeleton oil seal until it passes through the bearing; finally, align the right end face of the right shaft, the right end face of the bearing, and the right end face of the right-turn shaft sleeve; at this point, the assembly of the right-turn shaft assembly is completed.

[0054] In some embodiments, the left shaft assembly is composed of a wire protection sleeve 540; a shaft clamp 370, a gasket 380, a bearing, a left shaft sleeve, a left shaft; a left shaft sealing gasket, and a skeleton oil seal. The left shaft assembly is assembled as follows: first, press the bearing into the left end stepped hole of the left shaft sleeve, press it into place, and the end faces are flush; press the skeleton oil seal into the right end stepped hole of the left shaft sleeve, with the open end of the skeleton oil seal facing left, until the open end face fits the end face of the left end stepped hole of the left shaft sleeve; then put the shaft sealing gasket into the contoured groove on the right end face of the left shaft sleeve, and press it to the bottom; pass the left shaft from the end with the skeleton oil seal into the right shaft sleeve until it passes through the bearing; then put the gasket 380 on the outer groove at the left end of the left shaft, and clamp it into the shaft clamp 370; press the wire protection sleeve 540 into the inner groove at the left end of the left shaft; at this point, the left shaft assembly is assembled.

[0055] In some embodiments, grooves are provided on the sealing end faces of the left and right axial holes of the lamp body die-casting of the lamp body assembly 100, and the left lamp body sealing gasket is placed in the groove of the sealing end face of the left axial hole of the lamp body assembly 100, and the right lamp body sealing gasket is placed in the groove of the sealing end face of the right axial hole of the lamp body assembly 100, and the through holes on the sealing gasket are aligned with the end face screw through holes and pressed into place.

[0056] In some embodiments, the method of connecting the lamp body assembly 100 and the arm assembly 200 together is as follows:

[0057] First, align the axial hole of the lamp body assembly 100 with the axial hole of the arm assembly 200. After alignment, insert the right rotating shaft assembly into the right axial hole of the arm assembly 200 from the right side until the sealing end face of the right shaft fits with the sealing end face of the right axial hole of the lamp body assembly 100. The two end holes are aligned. From the inside of the lamp body, pass the mounting screw through holes on the circumference of the right axial hole of the lamp body assembly 100 (the through holes are all within the range of the sealing gasket), and tighten them into the threaded holes on the sealing end face of the right shaft. At this point, the right shaft in the right rotating shaft assembly has been fixedly connected to the lamp body assembly 100; the sealing end face of the right rotating shaft sleeve fits with the right axial hole of the arm assembly. The sealing end faces are fitted together, and the two end holes are aligned. Insert the mounting screw through the through hole on the right shaft sleeve at the right end of the right shaft assembly, and tighten the mounting screw into the threaded hole on the sealing end face of the right shaft hole of the arm assembly 200. At this point, the right shaft sleeve in the right shaft assembly is connected and fixed together with the arm assembly 200. Next, use the mounting screw to install the lamp body rotation limit plate 520 on the right end face of the right shaft sleeve. Use the mounting screw to fix the rotating pulley on the right end face of the right shaft. After pressing the wire protection sleeve 540 into the right side of the right wire tie plate 530, use the screw to fix the right wire tie plate 530 to the arm assembly 200.

[0058] Similarly, the left shaft assembly is inserted into the left shaft hole of the arm assembly 200 from the left side until the sealing end face of the left shaft fits with the sealing end face of the left shaft hole of the lamp body assembly 100, and the two end holes are aligned. From the inside of the lamp body, a mounting screw is passed through the mounting screw through holes on the circumference of the left shaft hole of the lamp body assembly 100 (the through holes are all arranged within the range of the sealing gasket), and tightened into the threaded hole on the sealing end face of the left shaft. At this point, the left shaft in the left shaft assembly has been fixedly connected to the lamp body assembly 100; the sealing end face of the left shaft sleeve fits with the sealing end face of the left shaft hole of the arm assembly 200, and the two end holes are aligned. The mounting screw is inserted from the through hole on the left shaft sleeve at the left end of the left shaft assembly, and the mounting screw is tightened into the threaded hole on the sealing end face of the left shaft hole of the arm assembly 200; at this point, the left shaft sleeve in the left shaft assembly is connected and fixed to the arm assembly 200; next, the left wire tie plate 530 is installed on the left end face of the left shaft sleeve with the mounting screw, and at this point, an assembly of the connecting shaft structure of an outdoor lamp arm and a lamp body is completed.

[0059] In some embodiments of the present application, the lamp body assembly 100 is connected and fixed to the right shaft and the left shaft as a whole, and a first sealing gasket 330 is installed between the sealing end face of the left shaft hole of the lamp body assembly 100 and the left shaft sealing end face on the left shaft, and a second sealing gasket 340 is installed between the sealing end face of the right shaft hole of the lamp body assembly 100 and the right shaft sealing end face on the right shaft. Therefore, the connection between the lamp body assembly 100 and the right shaft and the left shaft can be waterproof and dustproof. When the right shaft and the left shaft are driven to rotate, the lamp body assembly 100 will also rotate together; wherein, the left shaft and the right shaft extend into the left and right step shaft holes of the lamp body assembly 100 and are fixedly connected by screws; when the lamp body rotates, not only the screws bear the gravity of the lamp body, but also the part of the material of the lamp body and the left and right shafts extending into each other's body also bears the gravity of the lamp body, thereby strengthening the connection between the lamp body and the left and right shafts and improving the safety performance of the lamp.

[0060] Furthermore, the arm assembly 200 is respectively connected and fixed to the right-turn shaft sleeve and the left-turn shaft sleeve as a whole; and a third sealing gasket 430 is installed between the sealing end face of the left shaft hole of the arm assembly 200 and the sealing end face of the left-turn shaft sleeve on the left-turn shaft sleeve; a fourth sealing gasket 440 is installed between the sealing end face of the right shaft hole of the arm assembly 200 and the sealing end face of the right-turn shaft sleeve on the right-turn shaft sleeve; therefore, the connection parts between the arm assembly 200 and the right-turn shaft sleeve and the left-turn shaft sleeve respectively can be waterproof and dustproof; at this time, under the action of the two bearings in the right-turn shaft assembly and the left-turn shaft assembly, the lamp body assembly 100 can rotate around the shaft hole on the arm assembly 200.

[0061] Among them, the left wire tie plate 530 is fixed to the left rotating shaft sleeve with mounting screws, and is connected to the left rotating shaft sleeve as a whole, and the inner hole diameter of the left wire tie plate 530 is slightly smaller than the inner diameter of the outer ring of the bearing, so that the outer ring of the bearing in the left rotating shaft assembly can be pressed to prevent the bearing from moving to the left; since the step end surface of the right shaft of the right end surface of the inner ring of the bearing fits with the step end surface of the left shaft, the bearing cannot move to the right; therefore, the bearing in the left rotating shaft assembly is fixed in the axial direction and cannot move; similarly, the lamp body rotation limit plate 520 is fixed to the right rotating shaft sleeve with mounting screws, and is connected to the right rotating shaft sleeve as a whole, and the inner hole diameter of the lamp body rotation limit plate 520 is slightly smaller than the inner diameter of the outer ring of the bearing, so that the outer ring of the bearing in the right rotating shaft assembly can be pressed to prevent the bearing from moving to the right; since the step end surface of the left shaft of the inner ring of the bearing fits with the step end surface of the right shaft, the bearing cannot move to the left; therefore, the bearing in the right rotating shaft assembly is fixed in the axial direction and cannot move; at this point, the axial position of the lamp body assembly 100 and the arm assembly 200 is determined.

[0062] It should be noted that a skeleton oil seal is installed between the right-turn shaft sleeve and the right shaft to prevent external moisture or dust from entering the inner cavity of the arm from the outer diameter of the right shaft or the inner diameter of the right-turn shaft sleeve; a skeleton oil seal is installed between the left-turn shaft sleeve and the left shaft to prevent external moisture or dust from entering the inner cavity of the arm from the outer diameter of the left shaft or the inner diameter of the left-turn shaft sleeve;

[0063] Furthermore, the rotating pulley is fixed to the right end surface of the right shaft by means of mounting screws, and a certain gap is maintained with the right end surface of the lamp body rotation limiting plate 520; therefore, the rotating pulley is connected and fixed to the right shaft and the lamp body assembly 100 as a whole, and when the belt drives the rotating pulley to rotate, the lamp body assembly 100 rotates together with the rotating pulley;

[0064] Finally, the wiring harness passes through the left and right shaft holes and is fixed to the left and right wire binding plates 530 and 530 with cable ties respectively. Since the left and right wire binding plates 530 and 530 are both fixed to the arm assembly 200 and do not rotate with the lamp body, the wire harness is protected by the wire guards 540 at both ends to avoid friction with the inner holes of the right and left shafts and thus damage the wire harness.

[0065] It can be understood that the structure of the present application is simple and reasonable, the parts are easy to process, and the processing cost is saved; the overall structure is cleverly installed, with layers stacked and relying on each other, which improves the structural strength and safety performance of the lamp; by using a skeleton oil seal, it plays a sealing and waterproof role while reducing friction, reducing the motor load and improving the sealing and waterproof performance of the connection between the lamp body and the shaft, and the arm and the shaft.

[0066] Reference Figures 1 to 6The stage lamp of the second embodiment of the present application may be an outdoor stage lamp, and the stage lamp includes the lamp body structure of the first embodiment of the present application, and a sealing gasket is installed on the mating end surface of the lamp body and the rotating shaft to prevent external moisture or dust from entering the inner cavity of the lamp body from the mating end surface of the lamp body and the rotating shaft; the connecting screw holes of the lamp body and the rotating shaft are all arranged within the sealing range of the sealing gasket; further, a sealing gasket is installed on the mating end surface of the shaft sleeve and the arm to prevent external moisture or dust from entering the inner cavity of the arm from the mating end surface of the shaft sleeve and the arm, and the connecting screw holes of the shaft sleeve and the arm are all arranged within the sealing range of the sealing gasket; wherein, a shaft is installed between the rotating shaft and the shaft sleeve Bearing and skeleton oil seal, the skeleton oil seal is installed on the outside of the bearing; in this way, the rotating shaft and the sleeve can rotate with each other, and can also prevent external moisture or dust from entering the inner cavity of the arm from the outer diameter of the rotating shaft or the inner diameter of the sleeve; in addition, after the rotating shaft and the sleeve are assembled into an assembly, they are inserted from the axial hole in the inner cavity of the arm and from the outside of the axial hole of the lamp body, while making the lamp body and the rotating shaft match the end faces; the sleeve and the arm match the end faces; then use screws to fix the lamp body and the rotating shaft, the sleeve and the arm; in this way, the installation cooperation of the lamp body and the connecting shaft, the arm and the connecting shaft can extend into each other's body, ensuring the safe connection of the lamp body and the arm and the safe use of the lamp.
