Description

TECHNICAL AREA The present invention relates to the field of lighting masts, in particular a lighting mast with real-time adjustable pendant light alignment. STATE OF THE ART As a common building material in everyday life, a lamppost serves to support and fix a light fixture, ensuring the fixture is mounted at a specific distance from the ground and thus increasing its illuminated area. On some existing lampposts, a light fixture is suspended from one side of the post using a horizontal hanging rod. This concentrates the light beams on that side of the post, resulting in good illumination on that side. However, on the opposite side of the post, the light beams are blocked, preventing effective concentration and resulting in inadequate illumination.The horizontal suspension rod is welded to the light pole, and the upper part of the light fixture is detachably connected to the horizontal suspension rod via a bolt and nut. This means the light fixture's orientation relative to the pole is fixed, and no adjustment of the light fixture to accommodate different lateral positions of the pole is possible. Therefore, the light fixture is suspended from the pole, and illumination is only possible from a specific lateral position of the pole. Furthermore, the height of the light fixture is not adjustable, so the light intensity and illumination area cannot be adapted to the actual lighting situation. CONTENT OF THE PRESENT INVENTION The present invention is based on the objective of providing a light pole with real-time adjustable pendant light alignment, wherein a light pole enables real-time adjustment of the alignment of a pendant light relative to the light pole and the height at a specific orientation, so that the light can pivot back and forth from two opposite sides of the light pole to meet the lighting requirements for different orientations and to achieve a light intensity and illumination area in a specific direction. According to the invention, the problem is solved by the following technical embodiment: a light pole with real-time adjustable pendant light alignment comprises a base and a hollow light pole, wherein the light pole is fixedly connected to the uppermost area of ​​the base, wherein the upper end of the light pole is provided with a pole cap, the inner side wall of which rotatably interacts with the inner wall of the light pole, wherein a positioning recess extending upwards is formed at the edge of the pole cap; wherein a guide groove extending along the axial direction of the light pole is formed on the light pole, which passes through the end face of the upper end of the light pole;wherein a rotatable spindle and a worm gear, which rotatably interacts with the inner wall of the lamp rod, are provided within the lamp rod, wherein the upper and lower ends of the spindle each rotatably interact with the rod cap and the base respectively, wherein the upper end of the spindle is provided with a threaded section with which the worm gear engages in a self-locking manner and is connected to it;wherein the lamp pole further includes a horizontal suspension rod located in the guide groove and a handle for driving the spindle to rotate, wherein the handle passes through the side wall of the lamp pole and rotatably interacts with the inner wall of the lamp pole, wherein the inner end of the handle is drive-connected to the spindle, wherein the horizontal suspension rod slidably interacts with the guide groove, and wherein one end of the horizontal suspension rod extends to the outside of the lamp pole and the other end is height-adjustable and connected to the threaded section via a thread;wherein a first limiting piece and a second limiting piece, which serve to abut against the horizontal suspension rod, are firmly connected to the end face of the upper end of the lamp pole, wherein the first limiting piece is arranged at the edge of an end opening of the guide groove and the second limiting piece is arranged spaced apart from the first limiting piece, wherein, when the horizontal suspension rod abuts against the first limiting piece, the guide groove and the positioning recess are located on one and the same straight line in order to allow a back-and-forth movement of the horizontal suspension rod between the guide groove and the positioning recess. Preferably, an annular lubricating piece is provided inside the rod cap, on which an escape opening is formed that is directly opposite the positioning recess, wherein the outer side wall of the lubricating piece is firmly connected to the inner wall of the rod cap and the inner side wall of the lubricating piece has a clearance fit with the outer side wall of the lamp rod. Preferably, the lubricating element is made of polytetrafluoroethylene. Preferably, a first bevel gear is pushed onto the spindle, which is firmly connected to the spindle, and a second bevel gear, which engages with and is connected to the first bevel gear, is pushed onto the inner end of the handle. Preferably, the number of teeth of the first bevel gear is greater than the number of teeth of the second bevel gear. Preferably, a thrust bearing is provided between the uppermost area of ​​the spindle and the upper side wall in the rod cap, and between the lowermost area of ​​the spindle and the upper wall of the base. Preferably, the lower end of the spindle is provided with a smooth rod section onto which a radial bearing is pushed, wherein the lamp rod, the radial bearing and the spindle are rigidly connected to each other from the outside in. Preferably, a shaft coupling is provided between the threaded section and the smooth rod section, wherein the threaded section, the shaft coupling and the smooth rod section are rigidly connected to each other from top to bottom. Preferably, a connecting shaft is rigidly attached to the worm gear, passing through the side wall of the lamp rod, the connecting shaft rotatably interacting with the lamp rod, and a marking protrusion is provided on the side surface of the outer end of the connecting shaft. Preferably, an observation opening is provided on the lamp rod, which is directly opposite the threaded section, with a transparent closing plate being firmly attached to the observation opening. The foregoing embodiment of the present invention is characterized by the following advantageous effects: 1. In the present invention, a rotatable spindle is provided within the lamp pole, to the threaded section of which the horizontal suspension rod is connected via a thread. This rod extends through the guide groove on the lamp pole to the outside of the lamp pole, and its outer end is detachably connected to the uppermost part of a lamp, thereby suspending the lamp. The inner end of the horizontal suspension rod and the threaded section of the spindle together form a lead screw drive. When the handle on the lamp pole is turned, the handle sets the spindle in motion.Thus, the horizontal suspension rod is raised or lowered along the threaded section in the guide groove in the axial direction of the spindle, thereby raising or lowering the light fixture suspended from the horizontal suspension rod to adjust the light intensity and illumination area. 2. In the present invention, a worm gear is provided, and the worm gear and a worm shaft together form a self-locking worm drive, which prevents reverse rotation of the spindle when the external force on the handle is released and prevents the horizontal suspension rod from returning to its initial position. 3. In the present invention, the provision of a rod cap allows rotation of the horizontal suspension rod in the circumferential direction relative to the light fixture rod.When the horizontal suspension rod enters the positioning recess in the guide groove of the rod cap during lifting, it can no longer be raised, thus fixing the horizontal suspension rod and the spindle relative to each other. The spindle continues to rotate, thereby rotating the horizontal suspension rod synchronously around its axis. The horizontal suspension rod then pushes the rod cap, causing it to rotate synchronously until the horizontal suspension rod abuts the second stop. Due to the rotation of the horizontal suspension rod, the light fixture is moved to the opposite side of the light pole.This allows the light to swivel back and forth from two opposite sides of the light pole to meet the lighting requirements of different orientations. To return the light to its initial position, the handle is turned in the opposite direction, causing the spindle and the horizontal suspension rod to rotate synchronously until the horizontal suspension rod rests against the first stop. This returns the light to its initial position, with the positioning recess of the guide groove once again directly opposite it. The handle is then turned further, and the horizontal suspension rod falls along the spindle into the guide groove, after which its height can be adjusted.

DETAILED DESCRIPTION The technical design of the present invention will be discussed in more detail below using specific embodiments, although the invention is by no means limited to this. First example: As shown in Figs. 1, 2, 3, 4, 5 to 6, a light pole with real-time adjustable pendant light alignment comprises a base 1 and a hollow light pole 2. The light pole 2 is rigidly connected to the uppermost part of the base 1. The upper end of the light pole 2 is provided with a pole cap 4, the inner side wall of which rotatably engages with the inner wall of the light pole 2. A positioning recess 401, extending upwards, is formed at the edge of the pole cap 4; a guide groove 202, extending along the axial direction of the light pole 2 and passing through the end face of the upper end of the light pole 2, is formed on the light pole 2.Within the lamp pole 2, a rotatable spindle 8 and a worm gear 12, which rotatably engages with the inner wall of the lamp pole 2, are provided. The upper and lower ends of the spindle 8 each rotatably engage with the pole cap 4 and the base 1, respectively. The upper end of the spindle 8 is provided with a threaded section 801 with which the worm gear 12 engages and is connected in a self-locking manner. The lamp pole 2 also includes a horizontal suspension rod 5, located in the guide groove 202, and a handle 3 for driving the spindle 8 to rotate it. The handle 3 extends through the side wall of the lamp pole 2 and rotatably engages with the inner wall of the lamp pole 2. The inner end of the handle 3 is drive-connected to the spindle 8. The horizontal suspension rod 5 slidably engages with the guide groove 202.One end of the horizontal suspension rod 5 extends to the outside of the light rod 2 and the other end is height-adjustable via a thread connected to the threaded section 801; A first limiting piece 11 and a second limiting piece 9, which serve to abut against the horizontal suspension rod 5, are fixedly connected to the end face of the upper end of the light pole 2. The first limiting piece 11 is arranged at the edge of an end opening of the guide groove 202, and the second limiting piece 9 is spaced apart from the first limiting piece 11. When the horizontal suspension rod 5 abuts against the first limiting piece 11, the guide groove 202 and the positioning recess 401 are on the same straight line to allow back-and-forth movement of the horizontal suspension rod 5 between the guide groove 202 and the positioning recess 401. In a specific embodiment, teeth of the worm wheel 12 are arranged on a lateral end surface of the worm wheel 12. As can be seen from Fig. 2, a further development provides that an annular lubrication element 7 is provided inside the rod cap 4, on which an escape opening is formed that is directly opposite the positioning recess 401. The outer side wall of the lubrication element 7 is firmly connected to the inner wall of the rod cap 4 and the inner side wall of the lubrication element 7 has a clearance fit with the outer side wall of the lamp rod 2. The provision of the lubricating element 7 prevents an excessive gap between the inner side wall of the rod cap 4 and the outer side wall of the lamp rod 2, thus preventing wobbling of the rod cap 4 and increasing its rotational stability. Furthermore, the friction between the rod cap 4 and the outer side wall of the lamp rod 2, facilitated by the lubricating element 7, prevents direct contact between the two rods. In addition, the self-lubricating properties of the lubricating element 7 ensure smooth rotation of the rod cap 4. In the present embodiment, the lubricating element 7 is made of polytetrafluoroethylene. Polytetrafluoroethylene is also known as the king of plastics and is a common plastic product in this field. The handle 3 is connected to the spindle 8 in such a way that a first bevel gear 13 is pushed onto the spindle 8 and is firmly connected to it. A second bevel gear 14 is pushed onto the inner end of the handle 3, which engages with and is connected to the first bevel gear 13. Preferably, the number of teeth of the first bevel gear 13 is greater than the number of teeth of the second bevel gear 14. By adjusting the number of teeth of the first bevel gear 13 and the second bevel gear 14 in this way, a reduction gear is achieved between the handle 3 and the spindle 8, which makes it easier to turn the handle 3, so that the handle 3 can be turned easily. In the present embodiment, a thrust bearing 10 is provided between the uppermost region of the spindle 8 and the upper side wall in the rod cap 4 and between the lowermost region of the spindle 8 and the upper wall of the base 1. Preferably the lower end of the spindle 8 is provided with a smooth rod section 803 onto which a radial bearing is pushed, wherein the lamp rod 2, the radial bearing and the spindle 8 are rigidly connected to each other from the outside inwards. By providing the smooth rod section 803, the sliding of the radial bearing between the spindle 8 and the lamp rod 2 is made easier, thus improving the ease of machining and assembly. In another preferred embodiment, a shaft coupling 802 is provided between the threaded section 801 and the smooth rod section 803, wherein the threaded section 801, the shaft coupling 802 and the smooth rod section 803 are rigidly connected to each other from top to bottom. In addition to connecting to the threaded section 801 and securing the smooth rod section 803, the shaft coupling 802 also serves to limit the horizontal suspension rod 5. When the horizontal suspension rod 5 is lowered to its lowest position and rests against the shaft coupling 802, the shaft coupling 802 serves both to limit the horizontal suspension rod 5 and to support it to a certain degree. As can be seen from Fig. 6, it is preferably provided that a connecting shaft 15 is fixedly connected to the worm gear 12, which passes through the side wall of the lamp rod 2, wherein the connecting shaft 15 rotatably interacts with the lamp rod 2 and a marking protrusion 16 is provided on the side surface of the outer end of the connecting shaft 15. The marking recess 16 allows information to be obtained about the degree of wear of the worm gear 12 and its ability to effectively self-lock with the spindle 8. This is done by observing the worm gear 12 engaging with the threaded section 801 of the spindle 8 and rotating synchronously with it when the spindle 8 is turned. By observing the number of revolutions of the marking recess 16 on the connecting shaft 15, it can be determined whether there is significant wear and normal self-locking is possible, provided the number of revolutions is within a reasonable range. However, if the worm gear 12 is severely worn, it will not rotate synchronously with the spindle 8, will stop rotating altogether, or will rotate independently in the opposite direction. In this case, it can be determined that self-locking is no longer possible, and immediate maintenance or repair is necessary. As shown in Fig. 1, Fig. 2, Fig. 5 and Fig. 6, in some embodiments an observation opening is formed on the lamp rod 2, which is directly opposite the threaded section 801, with a transparent closing plate 201 being firmly attached to the observation opening. By providing the observation opening and the transparent cover plate 201, it is possible to directly observe the wear of the threaded section 801 from outside the lamp rod 2 and to initiate routine maintenance and repair in a timely manner in order to avoid impairing normal use. The present invention functions as follows: When the handle 3 is turned forward, the handle 3 sets the spindle 8 into forward rotation. This raises the horizontal suspension rod 5 along the axial direction of the spindle 8 in the guide groove 202. The positioning recess 401 on the rod end cap 4 is now directly opposite the guide groove 202. With further lifting, the horizontal suspension rod 5 enters the positioning recess 401, and the spindle 8 continues to rotate forward, while the horizontal suspension rod 5 cannot be raised any further, so that the horizontal suspension rod 5 and the spindle 8 are fixed relative to each other. The spindle 8 continues to rotate, thereby rotating the horizontal suspension rod 5 synchronously about the axis of the spindle 8. The horizontal suspension rod 5 then pushes the rod end cap 4 so that it rotates synchronously until the horizontal suspension rod 5 abuts the second limiting piece 9.Due to the rotation of the horizontal suspension rod 5, the luminaire 6 is moved to the opposite side of the light pole 2. Thus, the luminaire 6 can swivel back and forth between two opposite sides of the light pole to meet the lighting requirements of different orientations. To return the luminaire 6 to its initial orientation, the handle 3 is turned in the opposite direction, causing the spindle 8 and the horizontal suspension rod 5 to rotate synchronously until the horizontal suspension rod 5 rests against the first stop. This returns the luminaire 6 to its initial orientation, with the positioning recess 401 of the guide groove 202 once again directly opposite it. The handle 3 is then turned further, and the horizontal suspension rod 5 falls along the spindle 8 into the guide groove 202, after which its height can be adjusted. The embodiments described so far have been presented as preferred embodiments of the present invention; however, this in no way limits the embodiments of the invention. Other modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention shall be considered equivalent replacements that are covered by the scope of protection of the invention.
