Description

Technical Field

[0001] The present invention relates to the technical field of lighting equipment, and in particular to a retractable bracket suitable for stadium lighting lamps. Background Art

[0002] Good lighting conditions not only ensure the safety of athletes on the field, but also provide a high-quality viewing experience for spectators and meet the requirements of television broadcasts. The height adjustment function of the lighting plays a key role in adapting to the lighting needs of different scenarios.

[0003] Traditional stadium lighting has limitations when it comes to height adjustment. Some fixtures have their main illuminating element fixed to the top of the pole, making it impossible to adjust the height to suit specific needs. This means that for scenarios like small events, daily training sessions, or when specific areas require focused lighting, the lighting range and intensity cannot be flexibly adjusted, resulting in energy waste and difficulty in providing optimal lighting results.

[0004] Some stadium lighting fixtures with the function of adjusting the height of the lighting body often use steel wire ropes to control the descent of the lighting body. This method has many disadvantages. First, the steel wire rope is exposed to harsh outdoor environments for a long time and is easily eroded by rain, wind and sun, causing rust and corrosion on the surface, which greatly shortens its service life. Once the steel wire rope breaks, the lighting body will lose control, which will not only cause damage to the lamp, but may also pose a serious safety threat to people and facilities in the stadium. Secondly, the accuracy of the steel wire rope control descent is low. When adjusting the height of the lighting body, it is difficult to accurately locate the required height, and repeated debugging is often required. The operation is cumbersome and time-consuming. In addition, during operation, the steel wire rope will generate large friction between the pulley, fixtures and other components, which not only increases energy consumption, but also causes increased wear of components, requiring frequent maintenance and replacement of components, and increasing operating costs. Summary of the Invention

The drive assembly 112 includes a fixing sleeve 1121 fixedly connected to the inner wall of the lamp pole 11. A screw 1122 is rotatably connected to the fixing sleeve 1121. A docking hole is formed at the bottom of the screw 1122. A docking bolt 11222 is slidably connected to the docking hole.

[0045] A second fixing sleeve 1123 is fixedly connected to the interior of the lamp pole 11 below the first fixing sleeve 1121. A docking shaft 11231 is rotatably connected to the interior of the second fixing sleeve 1123. The bottom of the docking bolt 11222 extends to the interior of the second bayonet 11232 opened at the top of the docking shaft 11231 and is slidably connected thereto.

[0046] Push frame 1125 is slidably connected to the interior of lamp post 11, and its top extends to the bottom of top block 11223, which is rotatably connected to the outer wall of docking bolt 11222. Push frame 1125 has a push surface 11252 on its top that is slidably connected to top block 11223. Push frame 1125 is fixedly connected to the inner wall of lamp post 11 via telescopic rod 11251.

[0047] The lamp pole device 2 includes a lamp pole 21 slidably connected to the inner wall of the lamp pole 11 , and a fixing component 22 is provided on the top of the lamp pole 21 , and the fixing component 22 is used to fix the lighting body 23 .

[0048] By adopting the above technical solution, the fixed sleeve 1121 provides stable rotation support for the screw 1122, and the screw 1122 is connected to the docking shaft 11231 through the docking bolt 11222. Under normal circumstances, the docking bolt 11222 is inserted into the bayonet 2 11232 under the action of the spring 6 11221, so as to ensure that the output end of the drive motor 1124 drives the screw 1122 to rotate through the docking shaft 11231, thereby realizing the initial drive to lift the lamp pole 2 21. The push frame 1125 can slide in the lamp pole 1 11 and adjust its position through the telescopic rod 11251. When the telescopic rod 11251 pushes the push frame 1125 to move, the push surface 11252 squeezes the top block 11223, so that the docking bolt 11222 disengages from the bayonet 2 11232 and at the same time pushes the docking gear 11253 to engage with the gear 2 126, thereby driving the screw 2 127, thereby controlling the movement of the docking block 125.

[0049] The inner wall of the docking hole opened inside the fixing sleeve 1121 is square, the upper section of the docking shaft 11231 is square and the lower section is cylindrical, the inner walls of the docking hole and the second bayonet 11232 are both square, and a bayonet three 11233 is opened on the outer wall of the docking shaft 11231 near the bottom, the inner wall of the bayonet three 11233 is non-circular, and the outer side of the push frame 1125 is rotatably connected to the position of the bayonet three 11233, and a driving bayonet 11254 is opened on the top of the docking gear 11253. A driving motor 1124 is provided at the bottom inner side of the lamp pole 11, and the bottom end of the docking shaft 11231 passes through the driving bayonet 11254 and is fixedly connected to the output end of the driving motor 1124. At the same time, the bayonet three 11233 is connected to the driving bayonet 11254, and the shape of the inner wall on one side of the driving bayonet 11254 is adapted to the outer wall of the bayonet three 11233.

[0050] By adopting the above technical solution, the square docking hole opened in the fixing sleeve 1121 cooperates with the square upper section of the docking shaft 11231 to ensure that the screw 1122 and the docking shaft 11231 rotate synchronously, and the non-circular bayonet three 11233 at the bottom of the docking shaft 11231 docks with the driving bayonet 11254 on the top of the docking gear 11253, and the inner wall of one side of the driving bayonet 11254 adapts to the outer wall of the bayonet three 11233. When the lighting body 23 needs to be lowered, the telescopic rod 11251 pushes the push frame 1125, and the top block 11223 moves upward to make the docking bolt 11222 disengage from the bayonet two 11232. The driving bayonet 11254 docks with the bayonet three 11233 to make the docking gear 11253 engage with the gear two 126, so that the driving motor 1124 drives the screw two 127 to rotate and control the lighting body 23 to descend.

[0051] A docking assembly 12 is provided on the outer wall of the lamp pole 11 near the docking bolt 11222, and the docking assembly 12 includes a docking rod 121 fixedly connected to the outer wall of the lamp pole 11, and a docking block 125 is slidably connected inside the docking rod 121, and a screw 2 127 is rotatably connected inside the docking rod 121, and the screw 2 127 passes through the docking block 125 and the two are threadedly connected, and a gear 2 126 is rotatably connected to the position near the docking gear 11253 inside the docking rod 121, and a spring 6 11221 is provided at the top of the docking bolt 11222, one end of which is connected to the inner wall of the docking hole, for maintaining the stability of the docking bolt 11222 in the docking hole, and a plurality of limit bars 113 are provided inside the lamp pole 11, and a positioning slide groove 211 adapted to the limit bar 113 is provided on the outer wall of the lamp pole 21, for limiting the sliding of the lamp pole 21 in the up and down directions.

[0052] By adopting the above technical solution, screw 2 127 can control the lifting and lowering of docking block 125, and gear 2 126 rotates inside docking rod 121 near docking gear 11253. After engaging with docking gear 11253, the power of driving motor 1124 can be transmitted to screw 2 127. When the lighting body 23 needs to be lowered, telescopic rod 11251 pushes pushing frame 1125, and top block 11223 moves upward to make docking bolt 11222 compress spring six 11221 and disengage from bayonet 2 11232. When driving is switched, docking gear 11253 engages with gear 2 126, thereby driving screw 2 127 to rotate.

[0054] By adopting the above technical solution, the connecting block 2253 of the fixing component 1 22 is fixed to the top of the lamp pole 21, and its external fixing shell 1 221 is sleeved on the top of the lamp pole 21 through the sleeve 1 222. Under normal circumstances, the spring 1 2252 causes the locking rod 225 to extend out of the lock mouth 1 224 to achieve fixation. When the lighting body 23 needs to be lowered, the lamp pole 21 is lowered to make the fixing component 1 22 dock with the top of the lamp pole 1 11, and the screw 2 127 is inserted into the docking slider 2311 and the sleeve 223. When the lamp pole 21 continues to be lowered, the connecting block 2253 is blocked, and the extrusion block 1 22531 squeezes the cross-section 1 2251 of the locking rod 225, and the locking rod 225 retracts into the lock mouth 1 224 to release the lock on the lighting body 23. At this time, the spring 2 22532 is compressed. After the subsequent operation is completed, the auxiliary recovery position can be switched to drive, and the rotation of the screw 2 127 can make the lighting body 23 descend.

[0055] The lighting body 23 includes a sleeve block 231 that is sleeved on the outside of the fixed shell 221, and fixed components 232 are symmetrically arranged at both ends of the sleeve block 231. The outside of the fixed component 232 is fixedly connected to a docking slider 2311 near the fixed shell 221, and the fixed component 232 includes a fixed shell 2321 that is fixedly connected to the sleeve block 231.

A push rod one 2325 is located on the top of one end outside the fixed shell two 2321 and a bayonet one 23251 is provided. A magnetic part is provided on the bottom inside the bayonet one 23251. The locking block 2323 realizes the locking function through the push rod one 2325 and the plug rod 2327.

[0058] By adopting the above technical solution, the locking blocks 2323 located on either side of the second locking opening 2322 within the second fixed housing 2321 are equipped with third springs 2324 to ensure that they are normally retracted within the second fixed housing 2321. Under normal circumstances, the metal piece at the bottom of the insertion rod 2327 is inserted into the first locking opening 23251 of the push rod 1 2325 and attracted by the magnetic element, locking the locking blocks 2323. When the lighting body 23 is lowered to its lowest point, the insertion rod 2327 is pulled out of the first locking opening 23251, and the push rod 1 2325, pushed by the fourth spring 2326, moves toward the outside of the second fixed housing 2321. The first pressing surface no longer presses the second pressing surface, and the third spring 2324 pushes the locking blocks 2323 back into the second fixed housing 2321, releasing the lock on the lighting lamp 233.

[0059] The working principle and usage process of the embodiment of the present invention are as follows:

[0060] A mounting base 111 is provided at the bottom of the lamp pole 11, and the mounting base 111 is used to fix the lighting lamp 233. A sleeve 223 is provided at the top of both sides of the outer side of the fixing shell 221, and the sleeve 223 is aligned with the screw 2 127. There is no thread on the top of the screw 2 127. The docking slider 2311 is aligned with the top of the docking rod 121. A sealing groove 122 is provided on the outer side of the docking rod 121 away from the lamp pole 11. A partition plate 124 is slidably connected inside the sealing groove 122. One side of the partition plate 124 is provided with several springs 5 ​​123 with one end connected to the inner wall of the docking rod 121. The gear 2 126 is arranged at a position close to the docking gear 11253. A magnetic part is provided at the bottom inner side of the bayonet 1 23251, and a metal part is provided at the bottom end of the insertion rod 2327. After the insertion rod 2327 is inserted into the bayonet 1 23251, it will be adsorbed and fixed by the magnetic part.

[0061] In the normal state, the locking block 2323 in the fixing component 232 is retracted inside the fixing shell 2321. When the push rod 1 2325 is pushed, it will squeeze the extrusion surface 2 of the locking block 2323 through the extrusion surface 1, so that one end of the locking block 2323 enters the locking mouth 2322, thereby clamping the clamping block 234 inside the locking mouth 2322, thereby fixing the lighting lamp 233.

[0062] In normal state, the lighting body 23 is lifted to a high position by the lamp pole device 2, and the limit bar 113 cooperates with the positioning slide 211 to ensure that the lamp pole 21 is stably lifted and lowered. The docking block 125 is at the highest point inside the docking rod 121. At the same time, the spring 5 123 will push the partition plate 124 to close the internal space of the docking rod 121, and together with the docking block 125, the docking rod 121 is closed to reduce the entry of rainwater and dust. A threaded hole is provided at the bottom of the docking slider 2311 corresponding to the top of the screw rod 2 127. In the normal state, the telescopic rod 11251 pulls the push frame 1125 so that the push surface 11252 does not squeeze the bayonet 3 11233, so that the docking bolt 11222 is pushed by the spring 6 11221 and remains inserted in the bayonet 2 11232, so as to ensure that the output end of the drive motor 1124 drives the screw rod 1122 to rotate through the docking shaft 11231. At the same time, the push frame 1125 will pull the docking gear 11253, so that the drive bayonet 11254 is separated from the bayonet 3 11233.

[0063] When adjusting the height of the lighting body 23, it is only necessary to drive the motor 1124. The driving motor 1124 drives the screw 1122 to rotate through the docking shaft 11231. The rotation of the screw 1122 will control the lamp pole 2 21 to descend inside the lamp pole 11, thereby adjusting the height of the lighting body 23.

[0064] When the lighting body 23 needs to be lowered, the lamp pole 21 is first lowered to the fixing component 1 22 and connected to the top of the lamp pole 11. At the same time, the top of the screw rod 227 is inserted into the threaded hole of the docking slider 2311 and the sleeve 223, and the non-threaded section of the screw rod 227 is inserted into the sleeve 223. At the same time, the docking slider 2311 will fit with the docking block 125, and then the lamp pole 21 is controlled to be lowered. However, the fixing component 1 22 is blocked and cannot fall, so the lamp pole 21 is lowered and the connecting block 2253 is pulled down. The falling of the connecting block 2253 will squeeze the section 1 2251 of the locking rod 225 through the squeezing block 1 22531. After the squeezing, the section 1 2251 will drive the locking rod 225 to move relatively. At the same time, the end of the locking rod 225 located in the socket 2328 is retracted into the lock socket 1 224, and the lighting body 23 is unlocked.

[0065] Then the telescopic rod 11251 pushes the push frame 1125 to move, and the push frame 1125 moves by pushing the push surface 11252 to squeeze the top block 11223 to move upward. The top block 11223 moves upward and pulls the bottom end of the docking bolt 11222 out of the bayonet 2 11232. In this way, the drive of the screw 1122 can also be switched. The movement of the push frame 1125 will also push the driving bayonet 11254 to move, so that the driving bayonet 11254 is connected to the bayonet three 11233. At the same time, the docking gear 11253 moves and engages with the gear 2 126. The driving motor 1124 drives the docking gear 11253 to rotate through the docking shaft 11231, and the docking gear 11253 then drives the screw 2 127 to rotate through the gear 2 126.

[0066] The rotation of the second screw 127 controls the docking slider 2311 and the docking block 125 to descend along the docking rod 121. The falling of the docking slider 2311 drives the entire lighting body 23 to descend. During the falling process, the docking slider 2311 squeezes the partition plate 124 into the sealing groove 122. When the lighting body 23 descends to the lowest point, the insertion rod 2327 is pulled to disengage the bottom end of the latch 1 23251. After the insertion rod 2327 is disengaged, the push rod 1 2325 is no longer restricted. The spring 4 2326 pushes the push rod 1 2325 to move toward the outside of the second fixed shell 2321, thereby preventing the extrusion surface 1 from squeezing the extrusion surface 2. Then, the spring 3 2324 pushes the locking block 2323 to retract into the interior of the second fixed shell 2321, thereby releasing the lock on the lighting lamp 233, thereby realizing the quick disassembly and assembly of the lighting lamp 233.

[0067] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0068] Advantage 1. The present invention uses the driving component 112 in the lamp pole device 1, such as the driving motor 1124, to drive the docking shaft 11231 and the screw 1122 to rotate, thereby accurately controlling the lifting and lowering of the lamp pole 21 in the lamp pole 11, and thus flexibly adjusting the height of the lighting body 23, effectively solving the problem that the traditional partial lighting lamp 233 is fixed at the top of the lamp pole and cannot be adjusted in height as needed, and can meet the diverse needs of different scenarios such as small-scale competitions and daily training for lighting range and intensity.

[0069] Advantage 2: Unlike conventional methods that use steel cables to lower the lighting unit 23, this invention avoids the risk of rust and corrosion from long-term exposure to harsh outdoor environments, significantly extending the device's service life. Furthermore, since there's no risk of the lighting unit 23 losing control due to a broken cable, the safety of both players and facilities within the stadium is effectively ensured.

[0070] Advantage 3: When adjusting the height of the lighting body 23, through the coordinated operation of the various components of the drive assembly 112, such as the push frame 1125, the docking gear 11253, etc., it can be accurately positioned to the required height without repeated debugging. The operation is simple and convenient, saving time and labor costs.

[0071] Advantage 4: Since the structure that generates large friction between the wire rope and the pulley, fixing device and other components is abandoned, the present invention reduces energy consumption and component wear, reduces the frequency of maintenance and replacement of components, and thus reduces operating costs.

[0072] Advantage 5. The fixing assembly 232 of the present invention is cleverly designed. When the lighting body 23 drops to the lowest point, pulling the plug 2327 will cause the spring 4 2326 to push the push rod 1 2325 to move, causing the locking block 2323 to retract into the interior of the fixing shell 2321, which can quickly release the lock on the lighting lamp 233, enabling rapid disassembly and assembly of the lighting lamp 233, and facilitating maintenance and replacement of the lamp.

[0073] Advantage 6. The docking rod 121 in the docking assembly 12 is provided with a sealing groove 122, a partition plate 124 and a spring 123. Under normal conditions, the partition plate 124, pushed by the spring 123, together with the docking block 125, seals the docking rod 121, effectively reducing the entry of rainwater and dust, improving the protection performance of the device, and extending the overall service life of the device.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
