Description

Technical Field

[0001] The utility model belongs to the technical field of street lamp bases, in particular to a street lamp fixing base. Background Art

[0002] The street light fixing base is the base used to connect and fix the light pole. Its performance and firmness are the key to the firm installation of the street light pole.

[0003] Regarding the street lamp fixing base, in the prior art, after searching, the utility model patent with Chinese patent publication number CN206360456U discloses an underground fixing base for street lamp poles, such as Figure 1 As shown, it mainly includes a base column a and a fixing screw rod b. The base column a is cast and fixed in the pit, and the lamp pole can be directly installed on the fixing screw rod b and fixed with a nut.

[0004] In the actual implementation process of the street lamp fixing base similar to the above technical solution in the prior art, it was found that there are areas that need to be improved: the screws are directly cast vertically and fixed in the base column separately, and the screws have no gripping force in the horizontal direction, which makes the fixing strength of the screws poor, thereby affecting the fixing firmness of the screws. Utility Model Content

[0005] In view of the shortcomings and defects in the prior art, the purpose of the utility model is to provide a street lamp fixing base, which solves the problem that the screws in the prior art street lamp fixing base are all directly cast vertically and fixed in the base column, and the screws have no gripping force in the horizontal direction, resulting in poor fixing strength of the screws, thereby affecting the fixing firmness of the screws.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a street lamp fixing base, including multiple screws and a pit, a gravel cushion layer is arranged around the pit, a concrete seat cast on site by concrete is arranged in the gravel cushion layer, the screws are buried in the concrete seat, and the screws are connected by connecting rods, each of the screws is provided with multiple arc claws, the bottom of the screw is provided with multiple leveling seats that can support the bottom of the screw, and the top of the concrete seat is provided with an embedding groove.

[0007] As a further improvement of the present invention, the leveling seat includes a plurality of gaskets.

[0008] As a further improvement of the utility model, the outer side of the screw is provided with a galvanized layer.

[0009] As a further improvement of the utility model, the stone cushion layer is connected by glue.

[0010] As a further improvement of the utility model, a rubber pad is provided in the embedding groove.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. By connecting the screw brackets together, multiple screws can form a whole, improving the overall firmness. The existence of the connecting rod can also provide a certain fixing force and limit for the screw in the horizontal direction to prevent the screw from being pulled out as a whole. In addition, the screw is also provided with an arc claw, which can provide a certain gripping force for the screw, improve the connection firmness between the screw and the concrete seat, and prevent the screw from falling off.

[0013] In addition, a gravel cushion layer is set around the pit. When pouring concrete, it can firstly improve the hardness of the outer periphery of the concrete base, avoid the tilting of the concrete base caused by settlement due to insufficient soil hardness, and improve the installation effect of the lamp pole. Secondly, when pouring concrete, it can penetrate into the gravel cushion layer, improve the bonding connection between the concrete and the surrounding environment, thereby improving the overall firmness effect and improving the installation firmness of the lamp pole.

[0014] In addition, the setting of the leveling seat can, on the one hand, provide a certain supporting force for the screw, and on the other hand, facilitate the screw to find verticality and avoid the screw from tilting.

[0015] An embedding groove is provided on the top of the concrete seat, so that the lamp pole seat can be embedded in the embedding groove, thereby improving the installation effect of the lamp pole seat.

[0016] 2. By setting the leveling seat as a structure of multiple gaskets, it is convenient to adjust the height of the leveling seat according to the flatness of the stone cushion layer.

[0017] 3. By arranging the rubber pad in the embedded layer, the rubber pad can provide certain buffer protection. BRIEF DESCRIPTION OF THE DRAWINGS
