The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the word "over" a first feature or feature in a second feature may include the word "over" or "over" the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under" a second feature may include a first feature that is directly under and obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 1 and fig. 2, the adjustable cross arm hoop structure of this embodiment includes hoop assembly 1, a plurality of cross arms 2 and a plurality of connecting rods 3, hoop assembly 1 includes first hoop 11, second hoop 12 and a plurality of fixed plates 13, both ends of fixed plates 13 in the length direction are connected with first hoop 11 and second hoop 12 respectively, fixed plates 13 are provided with a plurality of fixing holes 131, the one ends of cross arms 2 and connecting rods 3 are all detachably connected with fixing holes 131, and the other ends of connecting rods 3 are connected with cross arms 2.

The fixed plate 13, cross arm 2 and the connecting rod 3 of the adjustable cross arm hoop structure of this embodiment form firm triangle connection structure between, and the connecting rod 3 and the one end of cross arm 2 all can be selectively fixed in different fixed orifices 131 on fixed plate 13 to realize the different height that sets up of cross arm 2, adjust the height of the cable (not shown in the figure) of erectting on cross arm 2, in order to satisfy the requirement of electric regulation, overall structure is simple, stability is high and be convenient for installation and regulation. As shown in fig. 3 and 4, the position of the cross arm 2 in fig. 3 is low, and the position of the cross arm 2 in fig. 4 is high, so that the installation positions of the cross arm 2 and the connecting rod 3 shown in fig. 4 can be obtained only by moving the cross arm 2 and the connecting rod 3 in fig. 3 integrally up to the three fixing holes 131, which is very convenient.

Preferably, the cross arm 2 is provided with a hinge lug 4, and one end of the connecting rod 3 is connected with the hinge lug 4 through a connecting shaft 5. In the present embodiment, the connecting rod 3 is hinged to the cross arm 2, so that the connecting rod 3 does not move at the end of the cross arm 2 connected to the fixed plate 13, and the connecting position of the connecting rod 3 and the fixed plate 13 is changed to change the included angle between the cross arm 2 and the horizontal plane, thereby adjusting the height of the other end of the cross arm 2 and the horizontal distance between the end and the fixed plate 13, and adjusting the erection height and the horizontal distance of the cable on the cross arm 2.

As shown in fig. 3 and 5, the installation state of the cross arm 2 shown in fig. 5 can be obtained by moving one end of the link 3 up by six fixing holes 131 in fig. 3.

Further, the distance from the end of the cross arm 2 connected with the fixed plate 13 to the hinge lug seat 4 is less than or equal to the length of the connecting rod 3. With the position of the hinged ear mount 4 fixed, the longer length of the link 3 allows the cross arm 2 to be adjusted to a more horizontal attitude, thereby allowing a greater range of attitude adjustment of the cross arm 2. When the distance from the end of the cross arm 2 connected with the fixed plate 13 to the hinge ear seat 4 is equal to the length of the connecting rod 3, the triangular area enclosed by the cross arm 2, the connecting rod 3 and the fixed plate 13 is an isosceles triangle with the fixed plate 13 as the base, the base length of the triangle is variable, and the length of the two waists is kept constant.

Preferably, an arc-shaped connecting plate 14 is further arranged between the first anchor ear 11 and the second anchor ear 12, and one side of the fixing plate 13 is perpendicular to the side surfaces of the first anchor ear 11 and the second anchor ear 12 and the surface of the connecting plate 14. The middle part of the fixing plate 13 can be effectively fixed by arranging the connecting plate 14, the strength of the fixing plate 13 is improved, the fixing plate is not easy to deform, and the cross arm 2 and the connecting rod 3 arranged on the fixing plate 13 can be more stable.

Preferably, the number of the fixing plates 13 is greater than two, and the present embodiment is preferably four, and since each fixing plate 13 can be provided with at least one cross arm 2, the number of the fixing plates 13 can be larger, and the number of the cross arms 2 can also be larger.

Further, the number of the fixing holes 131 in the fixing plate 13 is greater than three, and the greater the number of the fixing holes 131, the more the fixing points of the cross arm 2 and the link 3 are, the greater the position adjustment range of the cross arm 2 is, and in the present embodiment, the number of the fixing holes 131 is nine.

Further, four fixed plates 13 are equidistant on first staple bolt 11 and second staple bolt 12 to make first staple bolt 11 and second staple bolt 12's atress comparatively even, be favorable to prolonging first staple bolt 11 and second staple bolt 12's life, also make the interval between each cross arm 2 great simultaneously, the erection of the cable of being convenient for.

As shown in fig. 1 and 6, preferably, the end of the cross arm 2 connected to the fixing plate 13 is provided with a first ear plate 21 and a second ear plate 22, the first ear plate 21 and the second ear plate 22 are respectively disposed on both sides of the fixing plate 13, and the end of the cross arm 2 is fixed on the fixing plate 13 by a fixing member 6 passing through the first ear plate 21, the fixing hole 131 and the second ear plate 22. By adopting the design, the weight of the cross arm 2 is not concentrated on the same side of the fixed plate 13, so that the fixed plate 13 is not bent and deformed after being pressed for a long time, and the connection is firmer.

Furthermore, the fixing piece 6 is a bolt connection pair, the bolt connection pair is low in cost and very convenient to use, the bolt connection pair can be not screwed down firstly when the cross arm 2 needs to be rotated to adjust the posture in the installation process of the cross arm 2, the cross arm 2 is locked to fix the cross arm 2 when the cross arm 2 rotates to a needed angle, and the connection of the connecting rod 3 and the fixing plate 13 can also be connected through the bolt connection pair.

Preferably, a plurality of reinforcing hoops (not shown) are further disposed between the first hoop 11 and the second hoop 12 and connected to a plurality of fixing plates 13. When the interval between first staple bolt 11 and the second staple bolt 12 is great or the quantity of cross arm 2 is more, overall structure weight is great, in order to promote structural strength, reinforcing fixed effect, can add a plurality of enhancement staple bolts between first staple bolt 11 and second staple bolt 12 and realize.
