All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the invention provides a multifunctional hoop for an electric power cement pole, which comprises two fixed point structures 1 symmetrically arranged on the cement pole along the circumferential direction;

the fixed point structure 1 comprises a supporting structure, the supporting structure comprises a flexible attaching edge 11 used for attaching the cambered surface of the electric power cement pole, two ends of the flexible attaching edge 11 are fixedly connected with rigid supporting edges 12, and one ends of the two rigid supporting edges 12 far away from the flexible attaching edge 11 are connected through a cross rod, so that the supporting structure is trapezoidal; the rigid supporting edges 12 are provided with sliding holes 13;

two ends of the flexible connecting belt 2 respectively penetrate through the sliding holes 13 on the fixed point structure 1 in sequence, and two ends of the flexible connecting belt 2 are connected through the buckles 15 to form a closed loop;

and the extrusion tightening mechanism 14 is arranged on the supporting structure.

In this embodiment, the squeezing and tightening mechanism 14 squeezes the looped flexible connecting band 2 inward, and the flexible connecting band 2 contracts inward of the supporting structure, so that the length of the flexible connecting band 2 bound to the electric power concrete pole area contracts, and the length of the portion of the flexible connecting band 2 outside the supporting structure shortens, so that the portion is bound to the electric power concrete pole together with the fixed point structure 1.

As shown in fig. 1 and 2, the flexible attaching edge 11 includes an elastic rigid plate 111 connected between two rigid supporting edges 12, and fan-shaped friction blocks 112 are fixedly mounted on the side surface of the elastic rigid plate 111 close to the electric power cement pole at equal intervals; the fan-shaped friction blocks 112 are made of metal fan-shaped blocks with lines on the surfaces for increasing friction force, and a bending and shaping structure is arranged between the adjacent fan-shaped friction blocks 112.

The bending and shaping structure comprises a plurality of special-shaped clamping pieces 113 arranged on the side wall of the fan-shaped friction block 112 and a plurality of extruding sleeving grooves 114 arranged on the fan-shaped friction block 112, wherein the plurality of special-shaped clamping pieces 113 and the plurality of extruding sleeving grooves 114 in the adjacent fan-shaped friction blocks 112 are in one-to-one correspondence and are mutually nested, so that the adjacent fan-shaped friction blocks 112 are mutually connected.

The cross section of the special-shaped card 113 is a right triangle, and the bevel edge of the special-shaped card 113 is arranged towards the bottom of the extrusion sleeving groove 114; when the extrusion sleeving groove 114 extrudes the surface of the electric cement pole, the deformed clamping sheet 113 is extruded outwards by the deformation acting force generated by the extrusion sleeving groove 114, so that the static friction between the deformed clamping sheet 113 and the electric cement pole is increased.

Under the extrusion and traction action of the looped flexible connecting belt 2, the elastic rigid plate 111 deforms to be attached to the electric power cement pole, and at the moment, the gap between the adjacent fan-shaped friction blocks 112 shrinks, so that the special-shaped card 113 is gradually nested in the extrusion sleeving groove 114 until the fan-shaped friction blocks 112 are fixed on the electric power cement pole.

At this time, the profile card 113 is embedded into the extrusion sleeving groove 114 to a deeper depth due to the following bending of the elastic rigid plate 111, and the profile card 113 presses the extrusion sleeving groove 114, so that the extrusion sleeving groove 114 area of the fan-shaped friction block 112 is slightly separated, and the fan-shaped friction block 112 acts on the surface of the power cement pole in a layered multi-point manner.

Moreover, the surface of the power cement pole is not completely in a straight cylinder shape, but has a certain slight slope on the surface, so when the layered structure of the fan-shaped friction blocks 112 is pressed on the surface, the fan-shaped friction block 112 at the bottommost layer is pressed and deformed most, and when the fan-shaped friction block 112 at the bottommost layer is deformed, the acting force generated by the deformation of the part can reversely extrude the special-shaped card 113, and at the moment, the special-shaped card 113 is pressed on the surface of the power cement pole under the action of the pressing.

In the process, the fan-shaped friction block 112, the special-shaped clamping pieces 113, the extrusion sleeving grooves 114 and other structures are adopted, flexible connection among the fan-shaped friction blocks 112 is achieved, the stability of the fan-shaped friction blocks 112 is enhanced, the acting area of extrusion on the electric power cement rod is enhanced through the cooperative extrusion of the fan-shaped friction blocks 112 and the special-shaped clamping pieces 113, the static friction force at the position is increased, and the longitudinal deformation acting force of the fan-shaped friction blocks 112 through the special-shaped clamping pieces 113 is converted into the transverse extrusion acting force

Wherein, the included angle between the extension lines of the two rigid supporting sides 12 is less than or equal to a right angle. So as to ensure that the flexible connecting belt 2 can effectively contact the surface of the power cement pole, and the smaller the included angle is, the larger the contact area between the flexible connecting belt 2 and the surface of the power cement pole is.

As shown in fig. 3, the squeezing and tightening mechanism 14 includes a mounting body 141 fixedly connected to the vertex between the rigid supporting sides 12, a plurality of independent arc-shaped squeezing plates 142 are nested in the mounting body 141 from top to bottom at equal intervals, a plurality of positioning slots 146 are formed in the mounting body 141 at equal intervals, and the independent arc-shaped squeezing plates 142 are nested in the positioning slots 146 in a linearly slidable and locked manner. Wave groove 143 has all been seted up in the both sides of constant head tank 146, installs the locking tooth 144 that can rotate to the direction of keeping away from wave groove 143 on wave groove 143, and locking tooth 144 is connected with wave groove 143 through the shell fragment that resets, and locking groove 145 that is used for meshing locking tooth 144 has all been seted up to the both sides of independent arc stripper plate 142.

By hinging on the side of the locking tooth 144 remote from the locking groove 145, the locking tooth 144 can move in this direction when moving away from the locking groove 145, and in the opposite direction, the edge of the other end of the locking tooth 144 is blocked by a structure on the wave groove 143, where the structure can be a protruding-like structure formed to block, so that it can only move away from the locking groove 145.

Through the occlusion of the special shapes of the locking groove 145 and the locking tooth 144, when the independent arc-shaped pressing plate 142 is manually pressed by external force, the independent arc-shaped pressing plate 142 slides to the left and presses the flexible connection band 2, the locking groove 145 presses the locking tooth 144 to the direction away from the locking groove 145, so that the locking tooth 144 rotates to the direction, thereby contacting the limitation of the sliding of the independent arc-shaped pressing plate 142, and thus the independent arc-shaped pressing plate 142 can slide to the left side and cannot slide to the right side.

Wherein, the independent arc-shaped pressing plate 142 includes a contact part 1421 for approaching one end of the power cement pole, and a sliding part 1422 connected to the contact part 1421 and nested in the positioning groove 146, the locking groove 145 is opened on the sliding part 1422, and the adjacent contact parts 1421 contact each other. The contact part 1421 is formed by two platelike structures joint, and two platelike structures's opposite face difference fixed mounting has U-shaped lug 1423 and interlock groove, and two platelike structures pass through U-shaped lug 1423 and interlock groove joint, and the tank bottom of interlock groove 1424 rotates through the screw interlock with U-shaped lug 1423 junction and installs toper adjusting screw 1425. The U-shaped protrusion 1423 has a thickness that gradually decreases away from the interface with the bite groove.

The contact area of the flexible connecting belt 2 is increased by arranging the contact part 1421, so that the flexible connecting belt is prevented from being damaged to a large extent; the tapered adjusting screw 1425 is a tapered screw with an inward vertex, and by rotating the tapered adjusting screw 1425, the tapered adjusting screw 1425 penetrates into a connection between the U-shaped protrusion 1423 and the bottom of the engagement groove 1424, so that the tapered adjusting screw extrudes the U-shaped protrusion 1423, the outer side of the engagement groove 1424 of the U-shaped protrusion 1423 slightly moves, the length of the contact portion 1421 slightly increases, and by means of the special shape of the U-shaped protrusion 1423, the outer side of the U-shaped protrusion 1423 moves more, so that the engagement effect of the engagement groove 1424 is tighter, and the stability of structural connection is improved.

The layering of the flexible connecting band 2 is pressed by a plurality of independent arc-shaped pressing plates 142, so that the binding area of the power cement pole of the flexible connecting band 2 presents a special contact surface.

For example, the topmost independent arc-shaped pressing plate 142 is slightly deviated to the left side relative to the other independent arc-shaped pressing plates 142, so that the bent part of the top end of the flexible connecting band 2 is more, the top end of the flexible connecting band 2 is more tightly contracted, the bound area of the flexible connecting band 2 is slightly inclined, the gradient of the surface of the power cement pole is adapted, and the device is more closely attached and more tightly bound.

The sliding part 1422 is adjusted to move left for a larger amplitude, the conical adjusting screw 1425 is adjusted to move left for a smaller amplitude, and the adjustment process is faster and more accurate and the fitting degree is higher due to the combined use of two different precision adjustments.

The detachable buckle 15 for connecting the flexible connecting band 2 may be composed of a connecting piece and a plurality of screws for fixing the connecting piece and the flexible connecting band 2.

In conclusion, the flexible connecting band 2 is connected to be sleeved on the electric power cement pole in a looped mode, the flexible connecting band 2 and the flexible attaching edge 11 are tightly bound on the electric power cement pole through contraction of the extrusion tightening mechanism 14, in the process, the contraction amplitude of the flexible connecting band 2 can be controlled through the extrusion tightening mechanism 14, so that the device has the function of adapting to the electric power cement poles with different diameters, the device is flexibly bound, only the buckle 15 of the flexible connecting band 2 needs to be disassembled, the whole device can be completely disassembled, and the device has the rapid disassembly capability; and this device is owing to make flexible connection area 2, accessible extrusion tightening mechanism 14 carries out the layering extrusion to flexible connection area 2 for flexible connection area 2 produces the constraint face of slope to the electric power cement pole, with the slight slope that adapts to different electric power cement pole surfaces and has.
