Description

Technical Field

[0001] The utility model relates to the technical field of solar street lamps, in particular to a solar street lamp column fixing base. Background Art

[0002] Solar street lights are widely used in road lighting due to their energy-saving and environmentally friendly features. They are usually equipped with a mounting base. The existing mounting base is usually fixed to a concrete base with bolts. If the bolts are loose, the bottom plate is easily separated from the concrete base and the mounting tube may topple over. Therefore, loose bolts will affect the stability of the solar street light. In this case, it is difficult to ensure that the solar street light will not topple over in strong winds.

[0003] An existing Chinese patent (publication number: CN217082387U) discloses a mounting base for a solar street light, including a concrete base, a bottom plate fixedly installed inside the concrete base by bolts, a mounting tube provided on the top surface of the bottom plate, a street light pole installed inside the mounting tube, clamping plates provided on both sides of the street light pole, two sets of clamping plates connected by a mounting mechanism, the mounting mechanism including a first connecting block, a stud screw and a fixing ring, and the stud screw and the fixing ring are connected by a thread; by installing the two sets of clamping plates on the surface of the street light pole, the supporting function of the street light pole is realized, the street light pole can be effectively prevented from tipping over, and the stability of the device is improved.

[0004] In actual application of the above-mentioned solar street light mounting base, the base plate is fixed to the concrete base by bolts. If the bolts are loose, the base plate is easy to move away from the concrete base and the mounting tube may fall over. Therefore, loose bolts will affect the stability of the solar street light. In this case, it is difficult to ensure that the solar street light will not fall over in strong winds.

[0005] To this end, we propose a solar street lamp column fixed base to solve the above problems. Utility Model Content

[0006] The utility model provides a solar street lamp column fixing base, which solves the problem that in the actual application process of the existing solar street lamp installation base, the bottom plate is fixed to the concrete base by bolts. If the bolts are loose, the bottom plate is easy to move away from the concrete base and the installation tube will fall over. Therefore, the loosening of the bolts will affect the stability of the solar street lamp. In this case, there is a technical problem that it is difficult to ensure that the solar street lamp will not fall over after encountering strong winds.

[0007] In order to solve the above technical problems, the utility model provides a solar street light column fixing base, including a concrete base, a street light base is installed on the top of the concrete base, a lamp post is installed at the center of the top of the street light base, bolts are threadedly connected on the concrete base and the street light base, an anti-loosening component is arranged between the bolt and the street light base, the anti-loosening component includes a plurality of gaskets located between the bolt and the street light base and sleeved on the outside of the threaded end of the bolt, radial ratchet teeth integrally formed on the opposite side of two adjacent gaskets, and radial serrations integrally formed on the opposite side of two adjacent gaskets, the inclination angle of the radial ratchet teeth is greater than the pitch of the thread of the threaded end of the bolt.

[0008] Preferably, a hexagonal groove is integrally formed on the top of the bolt.

[0009] Preferably, a plurality of triangular pieces are installed between the street lamp base and the lamp post.

[0010] Preferably, a reinforcement ring is installed on the outer wall of the lamp post, a plurality of sleeves are installed on the bottom of the reinforcement ring, a screw rod is threadedly connected to the inner wall of the sleeve, and the bottom end of the screw rod abuts against the inner bottom wall of the hexagonal groove.

[0011] Preferably, a compression spring is provided between the sleeve and the screw rod.

[0012] Preferably, one end of the compression spring is connected to the sleeve, and the other end of the compression spring is provided with a friction pad, and the outer surface of the friction pad is integrally formed with anti-skid particles.

[0013] Preferably, a through hole is formed through the middle of the screw rod.

[0014] Compared with the related art, the solar street lamp column fixing base provided by the utility model has the following beneficial effects:

[0015] 1. In the utility model, the bolt is fixed by the tension formed by the radial ratchets on the opposite sides of the two gaskets, rather than the existing ordinary gaskets fixing the bolt only by increasing the friction. Because the inclination angle of the radial ratchets is greater than the pitch of the thread at the threaded end of the bolt, a wedge effect is generated on the head of the bolt to prevent the bolt from loosening. At the same time, the radial serrations increase the friction between the two gaskets and the street lamp base and the head of the bolt, further improving the anti-loosening effect and improving the stability of the street lamp base on the concrete base to ensure that the lamp post is not easy to fall over.

[0016] 2. In the utility model, the screw rod is rotated and its bottom end is in conflict with the inner bottom wall of the hexagonal groove, so that the bolt is not easy to move upward and prevented from loosening. The elasticity of the sleeve is utilized to prevent the screw rod from retracting into the sleeve without human power. By arranging a friction pad, the friction between the compression spring and the screw rod is increased, so that the screw rod is not easy to rotate without human power, thereby improving the effect of preventing the screw rod from retracting, thereby preventing the bolt from loosening and supporting the lamp post to prevent tipping.

[0027] Embodiment 1, by Figure 1-4 A solar street lamp column fixing base is provided, comprising a concrete base 1, a street lamp base 2 is installed on the top of the concrete base 1, a lamp post 3 is installed at the center of the top of the street lamp base 2, a bolt 4 is threadedly connected to the concrete base 1 and the street lamp base 2, an anti-loosening component 5 is arranged between the bolt 4 and the street lamp base 2, and the anti-loosening component 5 includes a plurality of gaskets 501 located between the bolt 4 and the street lamp base 2 and sleeved on the outside of the threaded end of the bolt 4, a radial ratchet 502 integrally formed on the opposite side of two adjacent gaskets 501, and a radial serration 503 integrally formed on the opposite side of two adjacent gaskets 501, and the radial ratchet 50 2 has an inclination angle greater than the pitch of the thread at the thread end of the bolt 4, and the bolt 4 is fixed by the tension formed by the radial ratchet teeth 502 on the opposite side of the two gaskets 501, rather than the existing ordinary gasket fixing the bolt 4 only by increasing the friction force. Because the inclination angle of the radial ratchet teeth 502 is greater than the pitch of the thread at the thread end of the bolt 4, a wedge effect is generated on the head of the bolt 4 to prevent the bolt 4 from loosening. At the same time, the radial serrations 503 increase the friction between the two gaskets 501 and the street lamp base 2 and the head of the bolt 4, respectively, further improving the anti-loosening effect, and improving the stability of the street lamp base 2 on the concrete base 1 to ensure that the lamp post 3 is not easy to tip over.

[0028] In addition, the top of the bolt 4 is integrally formed with a hexagonal groove 6 . The hexagonal groove 6 is provided to facilitate relevant staff to use a hexagonal wrench to rotate the bolt 4 , thereby facilitating tightening the bolt 4 to better fix the street lamp base 2 .

[0029] In addition, a plurality of triangular pieces 7 are installed between the street lamp base 2 and the lamp post 3. The triangular pieces 7 are provided to make the street lamp base 2 more stable after being connected to the lamp post 3, thereby preventing the lamp post 3 from detaching or falling on the street lamp base 2.

[0030] Embodiment 2, based on embodiment 1, refers to the attached Figure 1 and 4 A reinforcement ring 8 is installed on the outer wall of the lamp post 3, and a plurality of sleeves 9 are installed on the bottom of the reinforcement ring 8. A screw rod 10 is threadedly connected to the inner wall of the sleeve 9. The bottom end of the screw rod 10 conflicts with the inner bottom wall of the hexagonal groove 6. The screw rod 10 is rotated and its bottom end conflicts with the inner bottom wall of the hexagonal groove 6, so that the bolt 4 is not easy to move upward and prevents loosening. The elasticity of the sleeve 9 is utilized to prevent the screw rod 10 from retracting into the sleeve 9 without human power. By arranging the friction pad 12, the friction between the compression spring 11 and the screw rod 10 is increased, so that the screw rod 10 is not easy to rotate without human power, thereby improving the effect of preventing the screw rod 10 from retracting, thereby preventing the bolt 4 from loosening and supporting the lamp post 3 to prevent tipping.

[0031] In addition, a compression spring 11 is arranged between the sleeve 9 and the screw rod 10. The compression spring 11 in the initial state extends to the outside of the sleeve 9. After the screw rod 10 is located in the sleeve 9, the elasticity of the sleeve 9 is utilized to prevent the screw rod 10 from retracting into the sleeve 9 after the screw rod 10 is rotated and abutted against the inner wall of the hexagonal groove 6. This not only improves the support and anti-dumping effect of the lamp post 3 on the street lamp base 2, but also makes the bolt 4 not easy to loosen. One end of the compression spring 11 is connected to the sleeve 9, and the other end of the compression spring 11 is installed with a friction pad 12. The outer surface of the friction pad 12 is integrally formed with anti-slip particles. By providing the friction pad 12, the friction between the compression spring 11 and the screw rod 10 is increased, thereby making the screw rod 10 not easy to rotate without human power, thereby improving the anti-retraction effect of the screw rod 10, thereby preventing the bolt 4 from loosening and preventing the lamp post 3 from tipping over.

[0032] In addition, a through hole 13 is formed in the middle of the screw rod 10 . The through hole 13 makes it convenient to insert any metal rod into the screw rod 10 , and the screw rod 10 can be rotated conveniently through the metal rod.

[0033] Working principle:

[0034] To prevent the bolts 4 from loosening and improve the stability of the street lamp base 2 on the concrete base 1 to ensure that the lamp post 3 is not easy to fall over:

[0035] The bolt 4 is fixed by utilizing the tension formed by the radial ratchet teeth 502 on the opposite sides of the two washers 501, rather than the existing ordinary washers fixing the bolt 4 only by increasing the friction force. Because the inclination angle of the radial ratchet teeth 502 is greater than the pitch of the thread at the threaded end of the bolt 4, a wedge effect is generated on the head of the bolt 4 to prevent the bolt 4 from loosening. At the same time, the radial serrations 503 increase the friction between the two washers 501 and the street lamp base 2 and the head of the bolt 4, respectively, further enhancing the anti-loosening effect and improving the stability of the street lamp base 2 on the concrete base 1 to ensure that the lamp post 3 is not easy to tip over.

[0036] To prevent the bolt 4 from loosening and to support the lamp post 3:

[0037] The screw rod 10 is rotated and its bottom end is in conflict with the inner bottom wall of the hexagonal groove 6, so that the bolt 4 is not easy to move upward and prevents loosening. The elasticity of the sleeve 9 is utilized to prevent the screw rod 10 from retracting into the sleeve 9 without human power. By providing the friction pad 12, the friction between the compression spring 11 and the screw rod 10 is increased, so that the screw rod 10 is not easy to rotate without human power, thereby improving the effect of preventing the screw rod 10 from retracting, thereby preventing the bolt 4 from loosening and supporting the lamp post 3 to prevent tipping.

[0038] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
