Description

Technical Field

[0001] The utility model relates to the technical field of street lamp construction, and particularly relates to a stable embedded base structure for street lamps. Background Art

[0002] When installing existing street lamps to ensure stability, they are generally connected to the anchor bolts on the embedded base. However, when the embedded base is laid in a pit, there is a problem that the bottom of the pit is uneven, resulting in the inclination of the anchor bolts; the utility model patent with the application number 202323135653.4 discloses a cast street lamp base, which realizes the installation of the street lamp by directly connecting the lamp pole to the base first and then pouring concrete. Although it can solve the problem that the street lamp cannot be connected to the inclined anchor bolts, as a whole, it still has the problem of overall inclination because the drill rod is inserted into the soil layer as a whole, and there is room for improvement. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a stable embedded base structure for street lamps that can ensure stable and convenient connection of street lamps in view of the deficiencies in the above background art.

[0004] To achieve the above purpose, a stable embedded base structure for street lamps of the utility model adopts the following technical scheme:

[0005] A stable embedded base structure for street lamps includes a bottom plate. There are enclosing plates upward around the bottom plate. There are fixing holes on the bottom plate. A limiting rod passes through the fixing holes. The lower end of the limiting rod is a conical end. There is a thread on the outer periphery of the limiting rod. There is also a positioning plate above the bottom plate. The positioning plate is higher than the enclosing plate. There is a second fixing hole on the positioning plate. The limiting rod passes through the second fixing hole. There are two groups of nuts screwed on the limiting rod. The lower end surfaces of the nuts respectively abut against the positioning plate and the bottom plate.

[0006] The further improvement of the stable embedded base structure for street lamps of the utility model lies in that the size of the positioning plate is smaller than that of the bottom plate.

[0007] The further improvement of the stable embedded base structure for street lamps of the utility model lies in that there are positioning holes horizontally arranged on the limiting rod. A second limiting rod passes through the positioning holes. The second limiting rod passes through the enclosing plate. The second limiting rod and the limiting rod are tied together.

[0008] The further improvement of the stable embedded base structure for street lamps of the utility model lies in that the diameters of the fixing holes and the second fixing holes are larger than the diameter of the limiting rod and smaller than the diameter of the nut.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model uses a bottom plate, a surrounding plate and a limiting rod, and cooperates with pouring concrete to realize the stable design of the base, thereby ensuring the stability of the lamp post arranged connected thereto; at the same time, the limiting rod is limited by the positioning plate and the nut to ensure its vertical state, thereby ensuring the vertical stability of the lamp post connection.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] As Figure 1 shown, a stable embedded base structure for a street lamp includes a bottom plate 1. The bottom plate is square, and surrounding plates 2 are provided upward around the bottom plate. The bottom plate and the surrounding plates are integrally formed. Fixing holes 7 are provided on the bottom plate, and a limiting rod 3 is passed through the fixing holes. The lower end of the limiting rod is a tapered end, and threads are provided on the outer periphery of the limiting rod. A positioning plate 4 is further provided above the bottom plate. The positioning plate is higher than the surrounding plate. Second fixing holes are provided on the positioning plate. The limiting rod passes through the second fixing holes 8, and two groups of nuts 5 are screwed on the limiting rod. The lower end faces of the nuts respectively abut against the positioning plate and the bottom plate.

[0015] Preferably, the size of the positioning plate is smaller than the size of the bottom plate. It is convenient for the subsequent arrangement of components such as the second limiting rod and the nut, and is also convenient for pouring concrete.

[0016] Furthermore, positioning holes are horizontally arranged on the limiting rod, and a second limiting rod 6 is passed through the positioning holes. The second limiting rod passes through the surrounding plate, and the second limiting rod and the limiting rod are tied. The hole provided on the surrounding plate for the second limiting rod to pass through is larger than the second limiting rod.

[0017] The diameters of the fixing holes and the second fixing holes are larger than the diameter of the limiting rod and smaller than the diameter of the nut. It is convenient for the vertical adjustment of the limiting rod.

[0018] The working principle of the present utility model is as follows: Insert the limiting rod into the bottom of the pre-dug pit, then lay out the bottom plate and the surrounding plate, lay out the upper and lower nuts on the limiting rod so that the limiting rod passes through the bottom plate, then lay out the positioning plate, and the positioning plate is horizontally adjusted and positioned by the external positioning structure. Lay out the upper and lower nuts on the fiber rod so that the lower end surface of the nut is flush with the positioning plate, thereby realizing the vertical adjustment of the limiting rod. Then, make the lower nut press against the bottom plate, lay out the second limiting rod, and then pour concrete and install the lamp post. On the other hand, nuts can also be added below the positioning plate to support and position the positioning plate after the limiting rod is vertical, thereby facilitating the removal of the external horizontal adjustment and positioning structure of the positioning plate and facilitating pouring.

[0019] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
