The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments.

In the present invention, unless otherwise expressly specified and limited, a first feature "on" or "under" a second feature may include the first and second features in direct contact, or may include the first and second features Not directly but through additional features between them. Also, a first feature being "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature. The first feature being "below" the second feature includes that the first feature is directly below and diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

In addition, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature defined as "first" or "second" may expressly 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 a hoop assembly 1 , several cross arms 2 and several connecting rods 3 , and the hoop assembly 1 includes a first hoop 11 , a second hoop The hoop 12 and several fixing plates 13, the two ends of the fixing plate 13 in the length direction are respectively connected with the first hoop 11 and the second hoop 12, the fixing plate 13 is provided with several fixing holes 131, the cross arm 2 and the connecting rod 3 One end of the connecting rod 3 is detachably connected with the fixing hole 131 , and the other end of the connecting rod 3 is connected with the cross arm 2 .

A stable triangular connection structure is formed between the fixing plate 13 of the adjustable cross arm hoop structure, the cross arm 2 and the connecting rod 3 in this embodiment, and one end of the connecting rod 3 and the cross arm 2 can be selectively fixed on the fixing plate 13 In the different fixing holes 131 on the cross arm 2, different setting heights of the cross arm 2 can be realized, and the height of the cables (not shown in the figure) erected on the cross arm 2 can be adjusted to meet the requirements of electrical regulations, and the overall structure is simple. , High stability and easy installation and adjustment. As shown in Fig. 3 and Fig. 4, the position of the cross arm 2 in Fig. 3 is lower, and the position of the cross arm 2 in Fig. 4 is higher, and it is only necessary to move the cross arm 2 and the connecting rod 3 in Fig. 3 upward as a whole The three fixing holes 131 can obtain the setting positions of the cross arm 2 and the connecting rod 3 shown in FIG. 4 , which is very convenient.

Preferably, the cross arm 2 is provided with a hinged ear seat 4 , and one end of the connecting rod 3 is connected to the hinged ear seat 4 through a connecting shaft 5 . The cross arm 2 of the foregoing embodiment needs to move the cross arm 2 and the connecting rod 3 as a whole in order to adjust its height. In this embodiment, by hingedly connecting the connecting rod 3 and the cross arm 2, the end of the cross arm 2 that is connected to the fixing plate 13 can be made. In the case of no movement, the angle between the cross arm 2 and the horizontal plane is changed by changing the connection position of the connecting rod 3 and the fixed plate 13, so as to adjust the height of the other end of the cross arm 2 and the horizontal distance between this end and the fixed plate 13, At the same time, the erection height and horizontal spacing of the cables on the cross arm 2 are adjusted.

As shown in FIG. 3 and FIG. 5 , by moving one end of the connecting rod 3 in FIG. 3 upward by six fixing holes 131 , the setting state of the cross arm 2 shown in FIG. 5 can be obtained.

Further, the distance from one end of the cross arm 2 connected to the fixing plate 13 to the hinge ear seat 4 is less than or equal to the length of the connecting rod 3 . When the position of the hinged ear seat 4 is fixed, the longer length of the connecting rod 3 can adjust the cross arm 2 to a more horizontal posture, thereby realizing a wider range of posture adjustment of the cross arm 2 . When the distance between the connecting end of the cross arm 2 and the fixed plate 13 and 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 the bottom edge of the fixed plate 13 An isosceles triangle with variable bases and constant sides.

Preferably, an arc-shaped connecting plate 14 is also provided between the first hoop 11 and the second hoop 12, and one side of the fixing plate 13 is connected to the side surfaces of the first hoop 11 and the second hoop 12. The surface of the plate 14 is vertical. By arranging the connecting plate 14, the middle part of the fixing plate 13 can also be effectively fixed, the strength of the fixing plate 13 is improved, so that it is not easily deformed, and the cross arm 2 and the connecting rod 3 arranged on the fixing plate 13 can also be more stable.

Preferably, the number of the fixing plates 13 is more than two, and in this embodiment, the number is preferably four. Since at least one cross arm 2 can be provided on each fixing plate 13, the number of the cross arms 2 is also higher if the number of the fixing plates 13 is larger. More can be set.

Further, the number of fixing holes 131 on the fixing plate 13 is greater than three, and the more the number of fixing holes 131 is, the more the fixing points of the cross arm 2 and the connecting rod 3 are, and the more the position adjustment range of the cross arm 2 is. In this embodiment, the number of the fixing holes 131 is nine.

Further, the four fixing plates 13 are arranged at equal intervals on the first hoop 11 and the second hoop 12, so that the force of the first hoop 11 and the second hoop 12 is relatively uniform, which is beneficial to prolong the first hoop. The service life of the hoop 11 and the second hoop 12 also makes the distance between the cross arms 2 larger, which is convenient for the erection of cables.

As shown in FIG. 1 and FIG. 6 , preferably, one 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 , and the first ear plate 21 and the second ear plate 22 are respectively arranged on the On both sides of the fixing plate 13 , one end of the cross arm 2 is fixed on the fixing plate 13 by the fixing member 6 passing through the first lug plate 21 , the fixing hole 131 and the second lug plate 22 . With this design, the weight of the cross arm 2 will not be concentrated on the same side of the fixing plate 13 , which will cause the fixing plate 13 to bend and deform after being compressed for a long time, and at the same time, the connection will be more firm.

Further, the fixing member 6 is a bolt connection pair, which has a low cost and is very convenient to use. During the installation process of the cross arm 2, when the cross arm 2 needs to be rotated to adjust the posture, the bolt connection pair can be removed first. Tighten it, and then lock it to fix the cross arm 2 when the cross arm 2 is rotated to the required angle. The connection between the connecting rod 3 and the fixing plate 13 can also be connected by a bolt connection pair.

Preferably, a plurality of reinforcing hoops (not shown in the figure) are further arranged between the first hoop 11 and the second hoop 12 and are connected with a plurality of fixing plates 13 . When the distance between the first hoop 11 and the second hoop 12 is large or the number of cross arms 2 is large, and the overall structural weight is large, in order to improve the structural strength and enhance the fixing effect, the first hoop 11 This is achieved by adding a number of reinforcing hoops between the second hooping hoop 12 and the second hooping hoop 12 .
