Description

Technical Field

[0001] The invention relates to the technical field of street light pole bases, and in particular to a street light pole base which is convenient for maintaining the street light pole. Background Art

[0002] Street lights refer to lamps that provide lighting for roads. They generally refer to lamps within the range of road lighting in traffic lighting. Street lights are widely used in various places where lighting is needed. At present, street light poles are usually fixed directly with bolts when in use. Although this fixing method is stable, it requires manual climbing up the light poles for inspection and maintenance during maintenance, or the bolts need to be removed. Most street light poles are exposed outdoors. After being exposed to wind, rain and erosion by the natural environment, it is difficult to remove the street light poles with bolts, which affects the efficiency of maintenance.

[0003] To this end, the Chinese patent with the publication number "CN110513660B" announced "a street light pole base for easy maintenance of street light poles", whose main structure includes a pre-embedded seat, a connecting ring, a base, a mounting seat, a sliding hole and a spring seat. The street light pole base for easy maintenance of street light poles has the advantages of easy maintenance, etc., and solves the problem that street light poles are usually fixed directly with bolts when in use. Although this fixing method is stable, it requires manual climbing up the light pole for inspection and maintenance during maintenance, or it is necessary to remove the bolts. Most street light poles are exposed outdoors. After being exposed to wind, rain and erosion by the natural environment, it is difficult to remove the street light poles with bolts, which affects the efficiency of maintenance.

[0004] During the installation of street lamps, the lamp holder is generally a hollow structure, and the wires used to connect the street lamps need to pass through the lamp holder. The center of the lamp pole base, which is convenient for maintaining the lamp pole, is a solid structure or is limited by the space of the structure itself and cannot pass through the base to connect with the lamp above, resulting in structural limitations. In addition, the worm and tooth structure of the base are exposed to the outside, which will cause external humid gas to directly enter the interior of the lamp pole, causing fatal effects on the internal circuit. Therefore, the usage limitations are relatively large. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a street light pole base which is convenient for maintaining the street light pole. When maintaining the street light pole, the angle can be changed at the connection part of the street light pole, so that the street light pole is in a horizontal state which is easy to maintain, thereby reducing the difficulty of maintaining the street light pole. At the same time, the device does not affect the connection space of the wires from below, and therefore does not cause structural limitation. In addition, the device can perform necessary sealing treatment on the detachable area after installation, thereby creating a partition between the equipment and the external space, reducing the negative impact of humid gas on the electronic components inside the street light, and solving the above-mentioned technical problems.

When the longitudinal threaded sleeve 101 is rotated, since the lower threaded structure 104 includes an internal threaded structure provided on the circumferential surface of the lower threaded hole 102 and an external threaded structure provided on the rod body of the lower longitudinal threaded rod 106, the upper threaded structure 10 The upper threaded hole 103 includes an internal thread structure provided on the circumferential surface thereof and an external thread structure provided on the rod body of the upper longitudinal threaded rod 107, and the spiral direction of the lower thread structure 104 is opposite to the spiral direction of the upper thread structure 105. When the longitudinal threaded sleeve 101 rotates, according to the force characteristics of the thread, the lower longitudinal threaded rod 106 and the upper longitudinal threaded rod 107 are subjected to axial forces in different directions, and the lower longitudinal threaded rod 106 and the upper longitudinal threaded rod 107 are caused to move away from or approach each other, thereby generating a longitudinal support effect on the No. 1 pipe body 81, and finally transforming into a suspended support effect on the street lamp pole, which is convenient for repairing the street lamp.

[0036] The support height adjustment mechanism 10 includes a longitudinal threaded sleeve 101, the lower half of the longitudinal threaded sleeve 101 is provided with a lower threaded hole 102 with an open bottom end, the upper half of the longitudinal threaded sleeve 101 is provided with an upper threaded hole 103 with an open top end, the longitudinal threaded sleeve 101 is provided with a lower longitudinal threaded rod 106 installed in the lower threaded hole 102 through a lower threaded structure 104, the longitudinal threaded sleeve 101 is provided with an upper longitudinal threaded rod 107 installed in the upper threaded hole 103 through an upper threaded structure 105, a polygonal limiting rod 1011 is fixedly installed inside the longitudinal threaded sleeve 101, and the lower longitudinal threaded rod 106 and the upper longitudinal threaded rod 107 are provided with a plurality of holes for placing the polygonal limiting rod 1011 on the opposite end faces. The polygonal limiting hole 1010 of the polygonal limiting rod 1011, in order to prevent relative rotation between the components, it is necessary to make the structural shape of the cross-section of the polygonal limiting hole 1010 consistent with the structural shape of the cross-section of the polygonal limiting rod 1011, both of which are polygonal structures, and the structural dimensions of the cross-section of the polygonal limiting hole 1010 match the structural dimensions of the cross-section of the polygonal limiting rod 1011, a polygonal anti-slip protrusion structure 1012 of an integrated structure is arranged in the middle of the outer circumferential surface of the longitudinal threaded sleeve 101, the bottom end of the lower longitudinal threaded rod 106 is arranged with a lower component fixing groove 108 for fixing the installation of the shaft sleeve body 6, and the top end of the upper longitudinal threaded rod 107 is arranged with an upper component fixing groove 109 for fixing the installation support base 7.

[0038] When the No. 2 pipe body 84 and the No. 1 pipe body 81 are both in the longitudinal orientation, the No. 1 pipe body 81, the No. 2 pipe body 84 and the longitudinal support rod 85 can play the necessary supporting function. After the outer limit movable plate 99 is inserted into the polygonal limit groove 811, due to the elastic pressure provided by the coil spring 911, the bottom surface of the outer limit movable plate 99 will be in contact with the upper annular end surface of the annular sealing ring 812, thereby performing the necessary sealing treatment. At the same time, the contact between the outer limit movable plate 99 and the No. 2 pipe body 84 can realize the limiting effect between the components, prevent the street light pole from tilting, and ensure the stability of the work;

[0039] When it is necessary to repair the street light pole, use a rope, tie one end of the rope in the rope limit ring 3 and fix it, then apply tension to the rope, pull the horizontal limit slide bar 96 upward, and make the outer limit movable plate 99 withdraw from the polygonal limit groove 811, and then apply a thrust opposite to the rope tension to the street light pole, so that the street light pole tilts to one side, and then control the rope pay-off speed to make the street light pole fall slowly. When the street light pole tilts to a suitable position, rotate the longitudinal threaded sleeve 101. According to the force characteristics of the thread, the lower longitudinal threaded rod 106 and the upper longitudinal threaded rod 107 will be subjected to axial forces in different directions, and then the lower longitudinal threaded rod 106 and the upper longitudinal threaded rod 107 will appear to move away from or approach each other, thereby producing a longitudinal support effect on the No. 1 pipe body 81, and finally it will be converted into a suspended support effect for the street light pole, which is convenient for repairing the street light.
