The rotating shaft 3 slides up and down and is coaxially provided with a linkage column 35, which is a telescopic column with a square column structure, and the linkage column 35 protrudes downward to the outside of the shaft body 31.

[0032] See also Figure 1 and Figure 2The support seat 1 is provided with a driving member, which is a driving motor 11. The driving motor 11 is embedded and fixed in the support seat 1, and the output shaft of the driving motor 11 extends toward the rotating shaft 3 and is coaxially arranged. A linkage groove is provided at the end of the output shaft of the driving motor 11, and the linkage column 35 is inserted into the linkage groove, so that the linkage column 35 and the output shaft of the driving motor 11 are linked. When the driving motor 11 is started, the linkage column 35 is driven to rotate, and at this time, the linkage column 35 drives the rotating shaft 3 to enter a rotating state. The rotating shaft 3 includes a plurality of shaft bodies 31, and the plurality of shaft bodies 31 are evenly arranged up and down, and the upper and lower adjacent shaft bodies 31 are rotationally connected and coaxially arranged, and the linkage column 35 slides up and down on the lowest shaft body 31.

[0033] See also Figure 3 and Figure 4 The street lamp bracket also includes a control assembly 5, which is arranged on the shaft body 31 and is used to realize the mutual connection between the upper and lower adjacent shaft bodies 31. The control assembly 5 includes a control shaft 51, a control tooth 52 and a sliding tooth 53. The control shaft 51 is fixedly connected to the top of each shaft body 31 and corresponds to each other. The control shaft 51 and the shaft body 31 are coaxially arranged, and the control shaft 51 located at the uppermost shaft body 31 is rotatably connected to the mounting seat 2. A rotation groove 32 is formed on the side of the shaft body 31 facing away from the control shaft 51, and the rotation shaft 3 of the next adjacent shaft body 31 is inserted into the rotation groove 32, and the control shaft 51 is rotatably connected to the rotation groove 32, and the rotation groove 32 of the lowermost shaft body 31 is for the linkage column 35 to pass through.

[0034] The circumferential groove wall of the rotating groove 32 is connected to a slide groove 33, which extends in the circumferential direction and surrounds the control shaft 51. The sliding teeth 53 are fixed on the groove wall of the slide groove 33 away from the groove opening, and there are multiple sliding teeth 53 and they are evenly arranged in the circumferential direction. The control teeth 52 are fixedly connected to the outer peripheral side of the control shaft 51, and there are multiple control teeth 52 and they are evenly spaced in the circumferential direction, and the number of control teeth 52 increases continuously from top to bottom. The sliding teeth 53 are slidably connected in the slide groove 33, and the control teeth 52 and the sliding teeth 53 are meshed with each other. The control teeth 52 and the sliding teeth 53 are triangular tooth structures, and the control teeth 52 and the sliding teeth 53 are made of elastic materials, such as stainless steel.

[0035] See also Figure 3 and Figure 5 In the initial state, the control teeth 52 and the sliding teeth 53 abut against each other, so that the upper and lower adjacent shaft bodies 31 are linked. At this time, when the drive motor 11 is started, each shaft body 31 enters a rotation state at the same time.

[0036] See also Figure 1 and Figure 2The street lamp bracket also includes a rod sleeve 4 and a light source part 41. The rod sleeve 4 is sleeved on the outer peripheral side of the rotating shaft 3. The rod sleeve 4 corresponds to the shaft body 31 one by one, and the length of the rod sleeve 4 is equal to the length of the shaft body 31. A threaded section 36 is formed on the outer peripheral side of each shaft body 31. The threaded sections 36 of the upper and lower adjacent shaft bodies 31 are continuous, and the inner peripheral side wall of the rod sleeve 4 is threadedly connected to the threaded section 36.

[0037] See also Figure 3 The connecting column 21 is provided with a guide member for guiding the rod sleeve 4 to move in the vertical direction. The guide member is a guide bar 211. There are multiple guide bars 211 and they correspond to the connecting column 21 one by one. The guide bars 211 are fixed on the opposite side of the connecting column 21. A guide groove 42 extending in the vertical direction is formed on the outer peripheral side of the rod sleeve 4. The guide bar 211 slides up and down in the guide groove 42. A limiting bar 212 is fixedly connected to the side wall of the guide bar 211. A limiting groove 43 extending in the vertical direction is formed on the groove wall of the guide groove 42. The limiting bar 212 slides up and down in the limiting groove 43.

[0038] See also Figure 3 and Figure 5 , the light source unit 41 (the light source unit 41 is Figure 1 The rod sleeve 4 is detachably fixed to the outer peripheral side wall of one of the rod sleeves 4 by connecting bolts. When installing, the rod sleeve 4 provided with the light source part 41 is first placed at the bottom of the rotating shaft 3, and then the driving motor 11 is started, and the output shaft of the driving motor 11 enters the forward rotation state. At this time, the adjacent shaft bodies 31 enter the simultaneous rotation state through the contact between the control teeth 52 and the sliding teeth 53, so that the rod sleeve 4 and the threaded section 36 of the outer peripheral side wall of the rotating shaft 3 are threadedly connected. Since the guide strip 211 restricts the rotation of the rod sleeve 4, the rotating shaft 3 drives the rod sleeve 4 toward the mounting seat 2 (the mounting seat 2 is at Figure 2 4, and the top of the rod sleeve 4 abuts against the bottom of the mounting seat 2. At this time, the rod sleeve 4 is resisted, limiting the upward movement of the rod sleeve 4, and then the shaft body 31 corresponding to the rod sleeve 4 enters a stationary state, and the control tooth 52 slides on the sliding tooth 53, so that the lower shaft body 31 is in a rotating state; then the remaining rod sleeves 4 are installed according to the same steps, and when the top of the next rod sleeve 4 abuts against the previous adjacent rod sleeve 4, the corresponding shaft body 31 also enters a stationary state, until the top of the rod sleeve 4 threadedly connected to the lowermost shaft body 31 is resisted by the previous adjacent rod sleeve 4, and the driving motor 11 enters a stopped state.

[0039] See also Figure 1 The light source part 41 can be powered by solar energy or by connecting an external power source with wires. When the light source part 41 is connected to an external power source with wires, a wiring hole can be opened in the pole sleeve 4. When the pole sleeve 4 is installed, the wires are passed through the wiring holes one by one until the street lamp bracket is installed. Then, the wires are electrically connected to the external power source.

[0040] See also Figure 4 The street lamp bracket also includes a power assembly 6, which includes a power column 61, a power block 62 and a power spring 63. A receiving groove is formed on the side of the shaft body 31 facing away from the rotation groove 32, and the receiving groove extends in the vertical direction. The power column 61 is slidably connected to the receiving groove up and down and corresponds one to one. The power spring 63 is installed in the receiving groove, and the power spring 63 corresponds one to one with the receiving groove. The top of the power spring 63 abuts against the bottom of the power column 61, and the bottom of the power spring 63 abuts against the bottom groove wall of the receiving groove. When the spring elasticity of the power spring 63 is released, the power column 61 is driven to move out of the receiving groove. A power groove 34 is formed along the circumferential direction on the side of the shaft body 31 facing away from the control shaft 51. The power spring 63 drives the power column 61 to be inserted into the power groove 34. When the upper and lower shaft bodies 31 rotate relatively, the power column 61 slides in the power groove 34. The power column 61 has an arc surface structure formed on the side facing away from the power spring 63 . The arc surface structure slides on the groove wall of the power groove 34 away from the groove opening, thereby reducing the friction force generated when the power column 61 slides.

[0041] See also Figure 5 and Figure 6 The power block 62 is fixedly connected to the groove wall of the power groove 34 on the side away from the groove, and the power block 62 is inclined toward the groove side of the power groove 34 to form a power surface 621. When the drive motor 11 rotates forward and the adjacent shaft bodies 31 rotate relative to each other, the power column 61 slides with the power. At this time, the power column 61 is pushed into the receiving groove, and the power spring 63 enters a compressed state until the power column 61 passes through the power block 62, and the power spring 63 drives the power column 61 to slide out of the receiving groove. When the drive motor 11 reverses, the lower shaft body 31 first drives the power column 61 to slide in the power groove 34 until the power column 61 abuts against the side wall of the power block 62, and the upper and lower adjacent shaft bodies 31 are linked, and the threaded sections 36 of the upper and lower adjacent shaft bodies 31 are in an aligned and continuous state. At this time, the rod sleeve 4 (the rod sleeve 4 is in Figure 1 The light source unit 41 is marked in the middle and can continuously move downward until it is separated from the rotating shaft 3, so as to facilitate lowering the light source unit 41 when a fault occurs (the light source unit 41 is Figure 1 The height of the light source unit 41 is helpful to reduce the difficulty of maintenance.

[0042] See also Figure 1 and Figure 2 The street lamp bracket further includes a support pier 7, which is disposed between the support seat 1 and the rotating shaft 3. A through hole 73 is formed on the support pier 7, and the linkage column 35 passes through the through hole 73. The support pier 7 is a cylindrical structure, and the diameter of the support pier 7 is equal to the diameter of the rod sleeve 4.

[0043] See also Figure 3 and Figure 4A connecting ring 44 is fixedly connected to the bottom of the rod sleeve 4, and the connecting ring 44 is coaxially arranged with the rod sleeve 4. A connecting groove 74 is respectively provided on the side of the rod sleeve 4 facing away from the connecting ring 44 and on the top of the supporting pier 7. The connecting ring 44 is inserted into the connecting groove 74, so that adjacent rod sleeves 4 and the rod sleeve 4 and the supporting pier 7 are connected, which is beneficial to improving the supporting strength of the street lamp bracket.

[0044] See also Figure 1 and Figure 2 A clearance groove 12 is formed on the support seat 1, and the clearance groove 12 is located below the rotating shaft 3. The support pier 7 slides in the clearance groove 12, so that the support pier 7 can move to the bottom of the rotating shaft 3, which is convenient for the connecting ring 44 (the connecting ring 44 is Figure 4 (marked in the middle) snaps into the connecting groove 74 (the connecting groove 74 is Figure 4 The support seat 1 is provided with a support block 8, and the support block 8 slides in the clearance groove 12. The support block 8 is provided with a waist-shaped hole 83, and the drive motor 11 (the drive motor 11 is Figure 5 The output shaft of the support block 8 (marked in the middle) slides in the waist-shaped hole 83, reducing the possibility of the support block 8 interfering with the output shaft of the drive motor 11 when installed. When the support pier 7 moves to the bottom of the rotating shaft 3 and the connecting ring 44 is aligned with the connecting groove 74, the support pier 7 is pushed upward, and then the support block 8 is slid into the clearance groove 12, so that the bottom of the support pier 7 abuts against the top of the support block 8, and the support block 8 supports the support pier 7. A plurality of fixing bolts 81 are provided on the support block 8, and the fixing bolts 81 are threadedly connected to the support seat 1, so that the support block 8 and the support seat 1 are fixedly connected.

[0045] See also Figure 5 , a fixed sleeve 71 is sleeved on the outer peripheral side of the support pier 7, and the fixed sleeve 71 slides up and down on the support pier 7. A fixed block is fixedly connected to the inner peripheral side wall of the fixed sleeve 71, and a movable groove extending in the vertical direction is formed on the outer peripheral side of the support pier 7, and the fixed block slides up and down in the movable groove. A driving spring 72 is provided on the support pier 7, and the driving spring 72 is installed in the movable groove. The bottom of the driving spring 72 abuts against the top of the fixed block, and the top plate of the driving spring 72 abuts against the top groove wall of the movable groove. When the driving spring 72 is elastically released, it drives the fixed sleeve 71 to move downward. A fixed groove 82 is provided on the top of the support block 8. When the fixed sleeve 71 is relatively aligned with the fixed groove 82, the driving spring 72 drives the fixed sleeve 71 to be stuck in the fixed groove 82, so that the connection stability between the support pier 7 and the support block 8 is improved.

[0046] The implementation principle of a street lamp bracket in the embodiment of the present application is: When installing the street lamp bracket, first fix the support column 22, the connecting column 21 and the mounting seat 2 to the top of the support seat 1, then slide the linkage column 35 into the shaft body 31 and drive the rod sleeve 4 to slide to the bottom of the rotating shaft 3, then release the linkage column 35, so that the linkage shaft and the output shaft of the driving motor 11 are linked. Then start the driving motor 11 to make the rod sleeve 4 move upward continuously until it contacts the mounting seat 2. At this time, the uppermost shaft body 31 enters a stationary state, while the lower shaft body 31 is in a rotating state. Then follow the same steps to install the remaining rod sleeves 4. After the rod sleeves 4 are installed, the support pier 7 and the support block 8 can be installed and fixed.
