[0026] Example 1

[0027] This utility model provides an XY-axis precision adjustment arm device adapted to lamps of different power, such as Figures 1 to 6As shown, the device includes: a sliding base 1, a support arm 2, a first rotating component 3, and a second rotating component 5. The outer surface of the sliding base 1 is provided with a stop groove, which supports the weight of the lamp. The support arm 2 slides along the stop groove on the outer surface of the sliding base 1, and the support arm 2 is in contact with the stop groove. The sliding base 1 and the support arm 2 are connected by screws. The first rotating component 3 has a connector 4 inside, which is bolted to the bottom of the support arm 2. The support arm 2 rotates horizontally at the top of the first rotating component 3 via the bolts. Both sides of the first rotating component 3 have arc-shaped U-shaped holes. When the support arm 2 rotates at the top of the first rotating component 3, it drives the bolts to rotate along the arc. The inner wall of the long U-shaped hole rotates, and the outer surface of the bolt is connected to a nut by a thread. The second rotating component 5 is connected to the first rotating component 3 by a connector 4, and the second rotating component 5 rotates vertically on one side of the first rotating component 3 by the connector 4. The first rotating component 3 includes a connecting housing 301, a first bearing 302, a first baffle 303, a worm gear 304, and an L-shaped vertical bearing seat 305. The connecting housing 301 is connected to the support arm 2. The first bearing 302 is installed inside the connecting housing 301 through the first baffle 303. The L-shaped vertical bearing seat 305 is installed in the connecting housing 301. The worm gear 304 is connected to the first bearing 302 and the L-shaped vertical bearing seat 305 respectively. Inside the vertical bearing housing 305; the second rotating component 5 includes a connecting housing 401, a second baffle 402, a second bearing 403, a worm gear 404, a third bearing 405, a snap ring 406, and a third baffle 407. Both the first connecting housing 301 and the second connecting housing 401 have circular end faces, and they are fitted together through these circular end faces. The connecting member 4 passes through the second bearing 403 and the third bearing 405 inside the second rotating component 5 with zero clearance. The inner ring of the second bearing 403 is fitted with the surface of the connecting member 4. A gap is left between the first connecting housing 301 and the second connecting housing 401 to allow them to rotate together. Without interference, the outer surface of the connector 4 is threaded at the edge away from the first connecting housing 301, and is installed on the outer surface of the connector 4 by means of a snap ring 406 through a threaded connection. The worm 304 and the worm wheel 404 mesh with each other. The outer surfaces of the support arm 2 and the second connecting housing 401 are both engraved with angle markings. The second connecting housing 401 is connected to the first connecting housing 301 through the connector 4. The second baffle 402 is connected to the second connecting housing 401. The second bearing 403 is sleeved inside the worm wheel 404, and the worm wheel 404 is fixedly connected to one side of the second connecting housing 401. The third bearing 405 and the snap ring 406 are connected to the second connecting housing 401 through the third baffle 407.

[0028] The bolts, nuts, worm 304, and worm wheel 404 are used to position the first connecting housing 301 and the second connecting housing 401 after the angle is adjusted, thus avoiding the problem of misalignment of the first connecting housing 301 and the second connecting housing 401 after the angle is adjusted, thereby improving the efficiency of adjusting the angle of the first connecting housing 301 and the second connecting housing 401.

[0029] In use, the operator first fixes the slide rail fixing seat 1 onto the crossbeam or lamp post. Then, the operator slides the support arm 2 on the outer surface of the slide rail fixing seat 1 and installs the slide rail fixing seat 1 and support arm 2 together with screws. Next, the operator installs the connecting housing 301 onto the support arm 2 with bolts. Then, the operator rotates the connecting housing 301, causing the bolt to rotate horizontally along the inner wall of the arc-shaped U-shaped hole, observing the scale on the surface of the connecting housing 301. When the operator rotates the connecting housing 301 to the preset position, a nut is installed on the surface of the bolt, and the connecting housing 301 and support arm 2 are snapped together by the nut. Next, the operator installs the connecting housing 401 inside the connecting housing 301 via the connecting piece 4, and the worm 304 inside the connecting housing 301 meshes with the worm wheel 404 inside the connecting housing 401. At this point, the operator installs the retaining spring 406 on the outer surface of the connecting piece 4, and the retaining spring 406 is used to install the connecting housing 401 together with the connecting housing 301. When the operator needs to rotate the connecting housing... At step 401, a hex wrench is inserted into the worm gear 304, causing it to rotate. As the worm gear 304 rotates, the inner rings of the first bearing 302 and the L-shaped vertical bearing seat 305 rotate, thus restricting its rotation and preventing misalignment. The rotation of the worm gear 304, via the worm wheel 404, causes the connecting housing 401 to rotate vertically. This rotation of the connecting housing 401, in turn, drives the second bearing 403 and the third shaft... The outer ring of bearing 405 rotates, and then the staff observes the scale on the surface of connecting housing 2 401. When connecting housing 2 401 rotates to the required angle, the rotation of connecting housing 2 401 is stopped. Through the cooperation between bolts, nuts, worm 304, and worm wheel 404, the connecting housing 1 301 and connecting housing 2 401 are positioned after the angle is adjusted, avoiding the problem of misalignment of connecting housing 1 301 and connecting housing 2 401 after the angle is adjusted, thereby improving the efficiency of adjusting the angle of connecting housing 1 301 and connecting housing 2 401.

[0030] Specifically, a support arm 2 is slidably connected to the outer surface of the slide rail fixing seat 1, and the slide rail fixing seat 1 and the support arm 2 are fixedly installed by screws. A connecting housing 301 is fixedly installed at the bottom of the support arm 2 by bolts and nuts. A connector 4 is fixedly connected inside the connecting housing 301. A first bearing 302 and an L-shaped vertical bearing seat 305 are respectively installed on the inner walls of both ends of the connecting housing 301. The same worm gear 304 is installed on the inner ring of the first bearing 302 and the L-shaped vertical bearing seat 305. A first baffle is fixedly installed on the connecting housing 301 on one side of the first bearing 302. 303, a worm gear 404 is meshed with the outer surface of the worm 304, and a connecting housing 401 is fixedly connected to one end face of the worm gear 404. A second baffle 402 is fixedly installed inside the connecting housing 401. The outer ring of the second bearing 403 is fixedly installed on the inner wall of the worm gear 404, and the inner ring of the second bearing 403 is sleeved on the outer surface of the connecting member 4. A third bearing 405 and a snap ring 406 are installed inside the connecting housing 401 through a third baffle 407, and the snap ring 406 is threadedly connected to the outer surface of the connecting member 4. The third bearing 405 is sleeved on the outer surface of the connecting member 4.

[0031] To address the issue of preventing unexpected rotation of the worm gear 304 in the above example, the following solution is proposed: Figure 4 and Figure 5 As shown, a screw 6 is threadedly connected inside the connecting housing 301, and one end face of the screw 6 is in contact with the outer surface of the worm gear 304; a hexagonal groove is provided at one end of the worm gear 304 near the first baffle 303; it also includes a lamp mounted on the surface of the second rotating component 5, and the illumination direction of the lamp is adjusted by the cooperation of the first rotating component 3 and the second rotating component 5.

[0032] By restricting the worm gear 304 with the tightening screw 6, the problem of accidental rotation of the worm gear 304 is avoided, thereby preventing the second rotating component 5 from shifting after the angle is adjusted, thus improving the stability of the second rotating component 5 after the angle is adjusted.

[0033] In use, when the operator needs to rotate the worm 304, first rotate the tightening screw 6 in the opposite direction. When the tightening screw 6 rotates, it rotates along the threads inside the connecting housing 301, and is guided by these threaded grooves, causing the surface of the tightening screw 6 to gradually separate from the surface of the worm 304. At this time, the operator can rotate the worm 304. When the operator needs to prevent the worm 304 from rotating accidentally, rotate the tightening screw 6, causing one end of the tightening screw 6 to gradually move closer to the worm 304, and the surface of the tightening screw 6 to fit against the surface of the worm 304, thus restricting the worm 304. By restricting the worm 304 with the tightening screw 6, the problem of the worm 304 rotating accidentally is avoided, thereby preventing the second rotating component 5 from shifting after the angle is adjusted, thus improving the stability of the second rotating component 5 after the angle is adjusted.

[0034] Specifically, a screw 6 is threadedly connected inside the housing 301, and the surface of the screw 6 is in contact with the surface of the worm gear 304.

[0035] Working Principle: When using this device, the operator first fixes the slide rail fixing seat 1 onto the crossbeam or lamp post. Then, the operator slides the support arm 2 on the outer surface of the slide rail fixing seat 1 and installs the slide rail fixing seat 1 and support arm 2 together using screws. Next, the operator installs the connecting housing 301 onto the support arm 2 using bolts. Then, the operator rotates the connecting housing 301, causing the bolts to rotate horizontally along the inner wall of the arc-shaped U-shaped hole, and observes the scale on the surface of the connecting housing 301. When the operator rotates the connecting housing 301... When the bolt reaches the preset position, the nut is installed on the surface of the bolt, and the connecting housing 301 and the support arm 2 are snapped together by the nut. Then, the operator installs the connecting housing 401 inside the connecting housing 301 through the connector 4, and the worm 304 inside the connecting housing 301 meshes with the worm wheel 404 inside the connecting housing 401. At this time, the operator installs the retaining ring 406 on the outer surface of the connector 4, and the connecting housing 401 is installed together with the connecting housing 301 through the retaining ring 406. When the operator needs to rotate... When connecting the second housing 401, insert a hex wrench into the worm gear 304, and then rotate the worm gear 304 using the hex wrench. As the worm gear 304 rotates, it rotates within the first bearing 302 and the L-shaped vertical bearing seat 305. The first bearing 302 and the L-shaped vertical bearing seat 305 restrict the rotation of the worm gear 304, preventing it from shifting. The rotation of the worm gear 304, through the worm wheel 404, causes the second housing 401 to rotate vertically. The rotation of the second housing 401, in turn, drives the second bearing 403 and the... The outer ring of the three bearings 405 rotates, and then the staff observes the scale on the surface of the connecting housing 2 401. When the connecting housing 2 401 rotates to the required angle, the rotation of the connecting housing 2 401 is stopped. Through the cooperation between the bolts, nuts and worm 304 and worm wheel 404, the connecting housing 1 301 and connecting housing 2 401 after the angle adjustment are positioned, avoiding the problem of the connecting housing 1 301 and connecting housing 2 401 shifting after the angle adjustment, thereby improving the efficiency of the angle adjustment of the connecting housing 1 301 and connecting housing 2 401.

[0036] When the operator needs to rotate the worm gear 304, first rotate the tightening screw 6 in the opposite direction. As the tightening screw 6 rotates, it rotates along the threads inside the connecting housing 301, and these threaded grooves guide the tightening screw 6, causing the surface of the tightening screw 6 to gradually separate from the surface of the worm gear 304. At this time, the operator can rotate the worm gear 304. When the operator needs to prevent the worm gear 304 from rotating accidentally, rotate the tightening screw 6, causing one end of the tightening screw 6 to gradually move closer to the worm gear 304, and the surface of the tightening screw 6 to fit against the surface of the worm gear 304, thus restricting the worm gear 304. By restricting the worm gear 304 with the tightening screw 6, the problem of the worm gear 304 rotating accidentally is avoided, thereby preventing the second rotating component 5 from shifting after the angle is adjusted, thus improving the stability of the second rotating component 5 after the angle is adjusted.
