Description

Technical Field

[0001] The utility model relates to the technical field of lamp stands for road engineering, and more specifically, to a lighting lamp stand for road engineering. Background Art

[0002] Under current technical conditions, the construction and maintenance of road engineering lighting systems face significant challenges, especially during the use of lighting fixtures. Since the environment of road engineering is usually complex, including unstable climatic conditions, frequent mechanical vibrations, and alternating high and low temperatures, these factors work together to affect lighting equipment, especially cable connections, which can easily lead to blurring and damage of cable connections.

[0003] Cable fading refers to poor contact at the connection part, which may lead to unstable current transmission due to loose connectors, oxidation or other electrical contact problems. This phenomenon not only reduces the lighting effect, but also may cause electrical safety accidents, such as short circuits or fires. In addition, physical damage to the cable, such as insulation damage and cable breakage, is also a common problem. These damages are often caused by external forces, such as mechanical impact during construction, long-term ultraviolet exposure or rain erosion.

[0004] Although the current road lighting system and its supporting facilities have been designed and manufactured with certain environmental adaptability in mind, it is still difficult to effectively cope with the various challenges brought about by the above-mentioned complex environment in actual application. Existing reinforcement methods and maintenance measures often cannot fully cover or solve these problems, resulting in a significant reduction in the stability and reliability of the lighting system. This not only affects the nighttime driving safety of road users, but also increases maintenance costs, affecting the overall quality and benefits of road engineering projects. Utility Model Content

[0031] See also Figure 1-5 A road engineering lighting lamp stand comprises an intermediate box 1 and a telescopic rod 2, wherein the intermediate box 1 is mounted on the telescopic rod 2, a fixing mechanism is arranged on the intermediate box 1, and the fixing mechanism comprises a cable 3, a lighting lamp 4, a fixing tube 5, a telescopic mechanism, a limiting ring 6, a push spring 7, a push plate 8, a rubber ball 9, a contraction mechanism, a clamping spring 10 and a compensation ring 11, the lighting lamp 4 is mounted on the telescopic rod 2, one end of the cable 3 is electrically connected to the lighting lamp 4, the other end of the cable 3 passes through the fixing tube 5 and the intermediate box 1 and is electrically connected to the power supply device, the telescopic mechanism cooperates to connect the fixing tube 5 and the push spring 7, the push spring 7 is connected to the push plate 8, and the push plate 8 slides It is dynamically connected to the fixed tube 5, the limiting ring 6 is installed on the side wall of the fixed tube 5, the rubber ball 9 is installed on the push plate 8, a plurality of limiting holes 12 are opened on the limiting ring 6, the rubber ball 9 is stuck in the limiting hole 12, the contraction mechanism is connected to the fixed tube 5 and the clamping spring 10, the compensation ring 11 is installed in the middle position of the clamping spring 10, the telescopic mechanism includes a threaded tube 13 and a hexagonal sleeve 14, the threaded tube 13 is threadedly connected to the fixed tube 5, the push spring 7 is connected to the hexagonal sleeve 14, the hexagonal sleeve 14 and the threaded tube 13 are coaxially arranged, a thrust bearing 15 is slidably provided in the fixed tube 5, and the threaded tube 13 abuts against the thrust bearing 15.

[0032] In this embodiment, when the clamping is performed, the threaded tube 13 can be driven to rotate by the rotation of the hexagonal sleeve 14. Since the threaded tube 13 and the fixed tube 5 are threadedly connected, the thrust bearing 15 can be pushed to move along the fixed tube 5. The thrust of the rotation can be converted into a vertical thrust through the thrust bearing 15, and then the thrust is transmitted to the slider 17 through the receiving spring 18, so that the resulting slider 17 contracts, and then the clamping spring 10 clamps it on the side wall of the cable 3, thereby completing the fixing process. As the hexagonal sleeve 14 and the threaded tube 13 move downward, since the push plate 8 contacts the limit ring 6, the push spring 7 can generate a reverse thrust, thereby ensuring the stability of the threaded connection between the threaded tube 13 and the fixed tube 5, and the push plate 8 is fixed by the rubber ball 9 clamped in the limit hole 12.

[0033] See also Figure 3 and Figure 4 As an implementation method of a road engineering lighting lamp stand for a retraction mechanism: the retraction mechanism includes an inclined platform 16 and a slider 17, a plurality of inclined platforms 16 are provided, and the plurality of inclined platforms 16 are respectively installed on the inner wall of the fixed tube 5, the slider 17 is fitted on the inclined platform 16, and a plurality of receiving springs 18 are equidistantly provided on the upper end surface of each slider 17, and the receiving spring 18 abuts against the thrust bearing 15, and a inclined block 19 is provided on each slider 17, and an inclined groove 20 is provided on each inclined platform 16, and the inclined block 19 is slidably connected in the inclined groove 20, and a plurality of insertion holes 21 are provided on the side wall of the slider 17, and positioning rods 22 are respectively provided at both ends of each clamping spring 10, and the two positioning rods 22 are respectively inserted into the two insertion holes 21, and the clamping spring 10 is clamped on the cable 3, and a bonding plate 23 is provided on the inner wall of the slider 17, and the bonding plate 23 abuts against the cable 3.

[0034] More specifically, when the thrust is transmitted through the thrust bearing 15, the inclined block 19 on the slider 17 is stuck in the inclined groove 20, so that the slider 17 fits on the inclined platform 16, thereby ensuring the limited sliding of the slider 17 and the inclined platform 16. Since the slider 17 slides on the inclined platform 16 and is in a retracted state, the thrust can be effectively transmitted to the slider 17 through the receiving spring 18, thereby ensuring the stability of the clamping.

[0035] In summary, when the overall equipment is in use or running: when clamping, first, the rotation of the hexagonal sleeve 14 can drive the rotation of the threaded tube 13. Since the threaded tube 13 and the fixed tube 5 are threadedly connected, the thrust bearing 15 can be pushed to move along the fixed tube 5. The thrust of rotation can be converted into a vertical thrust through the thrust bearing 15, and then the thrust is transmitted to the slider 17 through the receiving spring 18, so that the resulting slider 17 contracts, and then the clamping spring 10 is clamped on the side wall of the cable 3, thereby completing the fixing process. As the hexagonal sleeve 14 and the threaded tube 13 move downward, since the push plate 8 contacts the limit ring 6, the push spring 7 can generate a reverse thrust, thereby ensuring the stability of the threaded connection between the threaded tube 13 and the fixed tube 5, and the push plate 8 is fixed by the rubber ball 9 clamped in the limit hole 12.

[0036] When the thrust is transmitted through the thrust bearing 15, the inclined block 19 on the slider 17 is stuck in the inclined groove 20, so that the slider 17 fits on the inclined platform 16, thereby ensuring the limited sliding of the slider 17 and the inclined platform 16. Since the slider 17 slides on the inclined platform 16 and is in a retracted state, the thrust can be effectively transmitted to the slider 17 through the receiving spring 18, thereby ensuring the stability of the clamping.

[0037] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
