Specific embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
Refering to Fig. 1, in one embodiment of electric pole of the present invention, electric pole 100 include electric pole main body 11, cross-arm 12 and
Supporting rack 13.
Wherein, one end of cross-arm 12 and 11 pivotable connection of electric pole main body, the other end of cross-arm 12 is movable end, can be with
It is rotated around cross-arm 12 and the tie point of electric pole main body 11.Supporting rack 13 is used to support cross-arm 12, its one end and electric pole master
11 pivotable connection of body, the other end of supporting rack 13 are fixed on when the rotation of cross-arm 12 is to electric pole main body 11 in predetermined angle
On cross-arm 12.
Wherein, predetermined angle actual installation needs can be determined as needed, such as can be 45 degree, 50 degree or 70
Degree etc..In present embodiment, predetermined angle is 90 degree.When installing electric pole, electric pole main body 11 is to be fixed on ground vertically
On, by making to make cross-arm 12 parallel to the ground for 90 degree of angles between cross-arm 12 and electric pole main body 11, can more easily into
Row circuit line transmits.
In present embodiment, as shown in Fig. 2, when need not use cross-arm 12, such as in storage or transportational process
In, 12 rotating shrinking of cross-arm can be returned, space can be saved, be conducive to store, transport.When electric pole is installed,
It is, for example, 90 degree of angles, then as shown in Figure 1, need to only rotate cross-arm 12 to being in predetermined angle between electric pole main body 11
The other end rotary expansion of supporting rack 13 is connected to the bottom of cross-arm 12, is fixed on vertically on ground in electric pole main body 11
When, cross-arm 12 applies supporting rack 13 downward pressure, and one end of supporting rack 13 is connected in electric pole main body 11, so that

Structure, to limit the rotation of supporting rack 13.Specifically, the first position limiting structure can be provided in recessed in electric pole main body 11
Slot 111, supporting rack 13, can by the openings of sizes of the groove 111 in the groove 111 and 11 pivotable connection of electric pole main body
To limit the rotation angle of supporting rack 13, the rotation of the more big then supporting rack 13 of axially open of groove 111 along electric pole main body 11
Angle is bigger, and the rotation angle of the smaller then supporting rack 13 of axially open of groove 111 along electric pole main body 11 is smaller, can basis
Predetermined angle between cross-arm 12 and electric pole main body 11 limits the angle rotatable of supporting rack 13.When supporting rack 13 is towards horizontal stroke
Load 12 rotation with support cross arm 12 and cause be 90 degree of required angles between cross-arm 12 and electric pole main body 11 when, groove 111
Edge of opening and supporting rack 13 be in contact, continue to rotate so as to limit supporting rack 13.
Wherein, in another embodiment, as shown in figure 3, the first position limiting structure can also be provided in supporting rack 13
On banking stop 131.Make that there is certain angle between banking stop 131 and supporting rack 13, when supporting rack 13 is revolved towards cross-arm 12
Turn with support cross arm 12 and cause be 90 degree of required angles between cross-arm 12 and electric pole main body 11 when, banking stop 131 and electricity
Line bar main body 11 is in contact, and continues to rotate so as to limit supporting rack 13.
With continued reference to Fig. 1, further, the second position limiting structure 112 is additionally provided in electric pole main body 11, to limit horizontal stroke
The rotation of load 12.Wherein, the second position limiting structure 112 is fixed in electric pole main body 11, cross-arm 12 rotation to electric pole main body
11 be in 90 degree required angles when, 12 and second position limiting structure 112 of cross-arm contacts, so as to the second position limiting structure 112 limitation cross-arm
12 continue to rotate, i.e., by the effect of the second position limiting structure 112, the rotation angle of cross-arm 12 is limited to the models of 0 to 90 degree
In enclosing.
Wherein, the first storage tank 113 of accommodating supporting rack 13 is additionally provided in electric pole main body 11.It is received when cross-arm 12 rotates
When being in 0 degree of angle during retraction electric pole main body 11, i.e., between cross-arm 12 and electric pole main body 11, supporting rack 13 can be rotated to the
In one storage tank 113, the storage of frame 13 easy to support and the contraction of cross-arm 12, and can further reduce volume.
In embodiments of the present invention, as depicted in figs. 1 and 2, the quantity of cross-arm 12 is two, accordingly the number of supporting rack 13
Amount is also two.Two cross-arms 12 respectively be located at electric pole main body 11 opposite sides, and using the center line of electric pole main body 11 as pair
Claim axial symmetry.
Further, electric pole further includes fixation kit.With reference to enlarged drawing shown in Fig. 4, fixation kit includes connecting plate
