[0002] The existing street lamp installation generally achieves the fixing of the street lamp by cooperating with the lamp pole base, embedded anchor bolts and nuts. However, there is an unstable connection when a single nut is screwed to the anchor bolt. In order to solve the above problems, the existing patent No. 202220576784.2 discloses a high-stability street lamp installation base, which increases the connection stability between the lamp pole and the base by adding a limiting structure on the outside of the base. However, the base is generally arranged below the ground, and the upper end surface of the base is flush with the ground. Using a limiting structure to connect the base requires excavating the ground outside the base, which is inconvenient to operate and has a complicated structure. There is room for improvement overall. Utility Model Content

[0007] A further improvement of the high-stability street lamp mounting base structure of the utility model is that an embedding opening is arranged on the vertical limiting portion for embedding the limiting rod.

[0008] A further improvement of the high-stability street lamp mounting base structure of the utility model is that a handle for rotation is arranged on the upper end of the positioning piece.

[0009] A further improvement of the high-stability street lamp mounting base structure of the utility model is that a second through groove is opened on the side wall of the fixing part, a second limiting rod is arranged in the second through groove, two ends of the second limiting rod respectively abut against the lamp pole and the positioning piece, and a buffer pad is arranged at one end of the second limiting rod close to the positioning piece.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the figure: 1 lamp pole, 2 embedded base, 3 base, 4 anchor bolt, 5 fixing part, 6 horizontal limit part, 7 vertical limit part, 8 limit rod, 9 positioning piece. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 As shown, a high-stability street lamp installation base structure includes a lamp pole 1 and an embedded base 2, a base 3 is provided at the lower end of the lamp pole, an anchor bolt 4 is provided on the embedded base, and the anchor bolt passes through the base and is threaded with a nut. The above structure is one of the conventional structures of existing street lamps and embedded bases. Further, a circular groove is provided upward on the lower end surface of the base, and an annular limiting groove is provided downward on the upper end surface of the embedded base. A limiting member is inserted at the lower part of the lamp pole, and the limiting member includes a cylindrical fixing part 5 inserted into the lamp pole and a limiting part placed in the groove and the limiting groove. A fixing groove is provided downward at the center of the upper end surface of the embedded base, and a through groove is provided between the fixing groove and the limiting groove. A limiting rod 8 is provided in the through groove, and the limiting rod abuts against the limiting part. A positioning member 9 is arranged in the fixing groove, and the positioning member abuts against the limiting rod and is threadedly connected with the fixing part. Adding a limiting member increases the limiting contact area with the embedded base and the lamp pole, thereby improving the stability of the connection.

[0016] Furthermore, the limiting part includes a horizontal limiting part 6 and a vertical limiting part 7. The horizontal limiting part is provided with a fixing hole for passing the anchor bolt. The vertical limiting part is provided with an embedding opening for embedding the limiting rod, so as to further ensure the limiting stability of the limiting member and the embedded base.

[0017] Furthermore, a handle for rotation is provided on the upper end of the positioning member, so that the staff can drive the positioning member from the inspection door to rotate and limit the limiting rod.

[0018] Furthermore, a second through slot is provided on the side wall of the fixing part, a second limiting rod is provided in the second through slot, two ends of the second limiting rod respectively abut against the lamp pole and the positioning member, and a buffer pad is provided at one end of the second limiting rod close to the positioning member, thereby increasing the interference between the limiting member and the lamp pole and improving the limiting stability.

[0019] The working principle of the utility model is as follows: the limiting piece is arranged on the embedded base, the lamp pole is installed, and then the positioning piece is rotated to make the positioning piece slide down and contact the limiting rod. At this time, the limiting rod is inserted into the embedding opening, which increases the limiting area as a whole, improves the connection stability, and ensures the high stability of the street lamp installation.
