[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] An electric power installation cross arm comprises a cross arm body 1, a mounting mechanism 2 for mounting the cross arm body 1 is arranged at the bottom of the cross arm body 1, and a fixing component 3 for improving the stability of the mounting mechanism 2 is arranged at the bottom of the mounting mechanism 2;

[0031] The mounting mechanism 2 comprises a first arc ring 201, a second arc ring 202, a first extension block 203, a second extension block 204, a first bolt 205, a nut 206 and a friction ring 207. The first arc ring 201 is fixedly connected to the bottom of the cross arm body 1, the second arc ring 202 is hinged to one end of the first arc ring 201, the first extension block 203 and the second extension block 204 are welded to the outer walls of the first arc ring 201 and the second arc ring 202 respectively, the first bolt 205 is threadedly connected to the inside of the second extension block 204, the nut 206 is threadedly connected to the outside of the first bolt 205, the friction ring 207 is welded to the side walls of the first arc ring 201 and the second arc ring 202, one end of the first bolt 205 passes through the first extension block 203 and is threadedly connected to the first extension block 203, and the number of friction rings 207 is several and evenly distributed.

[0032] Specifically, Figure 4 As shown, sealing rings 4 are welded inside the first arc ring 201 and the second arc ring 202 . There are several sealing rings 4 which are evenly distributed between two adjacent friction rings 207 .

[0033] Specifically, Figure 4 As shown, a drainage groove 5 is provided on the top of the sealing ring 4 to prevent rainwater from accumulating between the electric pole and the sealing ring 4. The number of the drainage grooves 5 is several and evenly distributed.

[0034] Specifically, Figure 3 As shown, a reinforcing rib 6 is bolted to the bottom of the cross arm body 1 , and the bottom of the reinforcing rib 6 is bolted to the side wall of the first arc-shaped ring 201 . There are two reinforcing ribs 6 and they are symmetrically arranged.

[0035] Specifically, Figure 5 As shown, a buffer pad 7 is bonded to the side wall of the first arc-shaped ring 201 , and the side wall of the buffer pad 7 is tightly fitted with the side wall of the second arc-shaped ring 202 .

[0036] Specifically, Figure 1 As shown, an anti-rust layer 8 is provided on the outer walls of the first arc ring 201 and the second arc ring 202. The anti-rust layer 8 is made of epoxy coating and is used to prevent the first arc ring 201 and the second arc ring 202 from rusting.

[0037] When in use, the user rotates the second arc ring 202, and then makes the first arc ring 201 and the second arc ring 202 located outside the pole, and then rotates the second arc ring 202 so that one end of the second arc ring 202 fits against the side wall of the buffer pad 7, and then screws the first bolt 205 into the first extension block 203 and the second extension block 204 in turn, and then fixes the second arc ring 202 with the nut 206. At this time, the friction ring 207 and the sealing ring 4 will fit tightly against the outer wall of the pole, thereby improving the fixing effect of the cross arm body 1. When it rains, rainwater will be discharged through the drainage groove 5 to prevent rainwater accumulation. Then the anti-rust layer 8 can prevent the first arc ring 201 and the second arc ring 202 from rusting and reducing their service life.

[0038] Specifically, Figure 3 As shown, the fixing assembly 3 includes a first arc plate 301, a second arc plate 302, a second bolt 303 and a third bolt 304. The first arc plate 301 and the second arc plate 302 are respectively welded to the bottom of the first arc ring 201 and the second arc ring 202, and the second bolt 303 and the third bolt 304 are respectively threadedly connected to the inside of the first arc plate 301 and the second arc plate 302.

[0039] Specifically, Figure 1 As shown, one end of the second bolt 303 and the third bolt 304 are both welded with a guide cone 9, and the guide cone 9 is made of stainless steel.

[0040] After the first arc ring 201 and the second arc ring 202 are fixed on the electric pole, the second bolt 303 and the third bolt 304 are rotated to enter the interior of the electric pole, thereby improving the fixing effect of the device and preventing the cross arm body 1 from shaking.

[0041] By adopting the above technical solution, the problem that an existing power installation cross arm is used to penetrate into the interior of the electric pole through the protruding tip to fix the device is solved, but the protruding tip may cause damage to the outer wall of the electric pole. When the device needs to be replaced, if the new device is fixed to the damaged part of the outer wall of the electric pole, the new device will not be firmly fixed.

[0042] Working principle: When in use, the user rotates the second arc ring 202, and then makes the first arc ring 201 and the second arc ring 202 located outside the electric pole, and then rotates the second arc ring 202 so that one end of the second arc ring 202 fits against the side wall of the buffer pad 7, and then screws the first bolt 205 into the first extension block 203 and the second extension block 204 in turn, and then fixes the second arc ring 202 through the nut 206. At this time, the friction ring 207 and the sealing ring 4 will fit tightly against the outer wall of the electric pole, thereby improving the fixing effect of the cross arm body 1. After the first arc ring 201 and the second arc ring 202 are fixed on the electric pole, the second bolt 303 and the third bolt 304 are rotated to make them enter the interior of the electric pole, thereby improving the fixing effect of the device and preventing the cross arm body 1 from shaking. When it rains, rainwater will be discharged through the drainage trough 5 to prevent rainwater accumulation. Then the anti-rust layer 8 can prevent the first arc ring 201 and the second arc ring 202 from rusting and reducing their service life.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
