Description

Technical Field

[0001] This utility model relates to the field of concrete utility pole technology, and in particular to a concrete utility pole with secondary locking. Background Technology

[0002] A concrete utility pole is a type of pole primarily composed of concrete. In existing pole structures, assembly involves fixing a pre-embedded base to the bottom surface using concrete, and then securing the pole assembly to the pre-embedded base using bolts and nuts.

[0003] The problem with the existing technology is that the connection between the threaded column and the nut is unstable when the nut becomes loose, which can cause the connection of the rod assembly to be unstable and prone to shaking. Further improvements are needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a secondary locking concrete utility pole.

[0005] A secondary locking concrete utility pole designed for this purpose includes an embedded base and a pole body. The pole body is provided with a connecting plate. The embedded base is provided with multiple locking posts arranged around the circumference. The connecting plate is provided with multiple arc-shaped grooves arranged around the circumference. The locking posts pass through the arc-shaped grooves and can move along the arc-shaped grooves.

[0006] The wall of the arc-shaped groove is provided with a first limiting coupling part, and the locking post is provided with a second limiting coupling part;

[0007] The locking pin moves from a first position to a second position relative to the arc-shaped groove, and the first limiting coupling part and the second limiting coupling part are inserted and coupled to each other.

[0008] The embedded base and the rod are equipped with a locking component, which is used to restrain the embedded base and the rod from rotating relative to each other.

[0009] Preferably, the first limiting coupling part is a coupling groove, and the second limiting coupling part is a coupling block, wherein the coupling block is movably inserted into the coupling groove.

[0010] Preferably, the connecting plate is provided with a plurality of mounting holes, and the connecting plate is provided with a plurality of threaded holes corresponding to the mounting holes;

[0011] The locking assembly includes a locking bolt passing through the mounting hole, the locking bolt being threadedly connected to the threaded hole.

[0012] Preferably, the locking post is a bolt post, and the locking post is threaded with a locking nut, and the connecting plate is clamped and fixed between the locking nut and the connecting plate.

[0013] Preferably, an annular spring is provided between the locking nut and the connecting disc.

[0014] Preferably, the connecting plate is provided with a connecting protrusion ring, which fits against the peripheral wall of the pre-embedded base.

[0015] Preferably, the mounting hole is provided on the connecting protrusion ring;

[0016] The threaded hole is located on the peripheral wall of the embedded base.

[0017] Preferably, the mounting hole is a countersunk hole.

[0018] Compared with the prior art, this invention, through the cooperation of the locking post and the arc-shaped groove, allows the first and second limiting coupling parts to interlock and couple, thereby constraining the rod body to move upward relative to the pre-embedded base and reducing swaying. Simultaneously, the locking assembly constrains the pre-embedded base and the rod body to rotate relative to each other. This prevents the first and second limiting coupling parts from separating, and simultaneously constrains the pre-embedded base and the rod body together, achieving secondary locking and improving overall locking stability.

[0033] See Figures 1-6 A type of concrete utility pole with secondary locking includes a pre-embedded base 10 and a pole body 20. The pole body 20 is provided with a connecting plate 210. The pre-embedded base 10 is provided with multiple locking posts 110 arranged around its circumference. The connecting plate 210 is provided with multiple arc-shaped grooves 220 arranged around its circumference. The locking posts 110 pass through the arc-shaped grooves 220 and can move along the arc-shaped grooves 220.

[0034] The arc-shaped groove 220 is provided with a first limiting coupling part 420 on its groove wall, and the locking post 110 is provided with a second limiting coupling part 410.

[0035] The locking pin 110 moves from a first position to a second position relative to the arc groove 220, and the first limiting coupling part 420 and the second limiting coupling part 410 are inserted and coupled to each other.

[0036] The embedded base 10 and the rod 20 are provided with a locking component 30, which is used to restrain the embedded base 10 and the rod 20 from rotating relative to each other.

[0037] In the embodiment of the concrete utility pole, the first and second limiting coupling parts can be interlocked and coupled by the locking post and the arc-shaped groove to constrain the pole body from moving upward relative to the embedded base, thus reducing swaying. Simultaneously, the locking assembly can constrain the embedded base and the pole body from rotating relative to each other. This prevents the first and second limiting coupling parts from separating, and simultaneously binds the embedded base and the pole body together, achieving secondary locking and improving overall locking stability.

[0038] During assembly, the pre-embedded base 10 is fixed to the ground by concrete. Then, the rod 20 is lifted and assembled by hoisting, so that the locking post 110 is inserted into the arc groove 220. The connecting plate 210 is made to fit with the pre-embedded base 10. Then, the rod 20 and the connecting plate 210 are driven to rotate so that the first limiting coupling part and the second limiting coupling part are inserted and coupled to each other. Finally, the pre-embedded base 10 and the rod 20 are locked by locking components to restrain them so that they will not rotate relative to each other.

[0039] like Figure 4 As shown, the first limiting coupling part 420 is a coupling groove, and the second limiting coupling part 410 is a coupling block. The coupling block is movably inserted into the coupling groove. That is, as the rod 20 rotates relative to the pre-embedded base 10, the coupling block can be inserted into or detached from the coupling groove.

[0040] like Figure 6 As shown, the connecting plate 210 is provided with a plurality of mounting holes 240, and the connecting plate 210 is provided with a plurality of threaded holes 100 corresponding to the mounting holes 240; the locking assembly 30 includes a locking bolt 310 passing through the mounting hole 240, and the locking bolt 310 is threadedly connected to the threaded hole 100.

[0041] like Figure 6 As shown, the locking post 110 is a bolt post, and the locking post 110 is threadedly connected to the locking nut 120. The connecting plate 210 is clamped and fixed between the locking nut 120 and the connecting plate 210.

[0042] Furthermore, an annular spring is provided between the locking nut 120 and the connecting disc 210.

[0043] like Figure 6 As shown, the connecting disc 210 is provided with a connecting protrusion 230, which is in contact with the periphery of the pre-embedded base 10.

[0044] like Figure 6 As shown, the mounting hole 240 is provided on the connecting protruding ring 230; the threaded hole 100 is provided on the peripheral wall of the embedded base 10.

[0045] In this utility model, the mounting hole 240 is a countersunk hole.

[0046] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
