Detailed Description

Referring to fig. 1-3, the present utility model provides a technical solution: a telescopic branch line pole, which comprises a loop bar 1 and an inner bar 2;

an inner rod 2 is movably arranged in the loop bar 1, a tooth slot 6 is formed in the outer wall of one side of the inner rod 2, a bracket 4 is fixedly arranged on one side, close to the tooth slot 6, of the outer wall of the loop bar 1, a sleeve 7 is fixedly arranged in the bracket 4, a plug pin 8 is movably arranged in the sleeve 7, and a plug block 11 is fixedly arranged at the inner end of the plug pin 8;

the bottom of the insertion block 11 is designed into an inclined plane, a spring seat 10 is fixedly arranged on the outer wall of the plug pin 8 and positioned in the sleeve 7, and a reset spring 9 is sleeved on one side of the spring seat 10 and positioned on the plug pin 8.

In this kind of technical scheme, can realize through the cooperation of inserted block 11, tooth's socket 6, bolt 8 and reset spring 9 that interior pole 2 is located the loop bar 1 and directly draw out and use, and in inserted block 11 inserts tooth's socket 6, and the top is right angle structure, make its interior pole 2 unable direct reception get back to in the loop bar 1, only can accomplish the work of retrieving of interior pole 2 need pulling bolt 8 this moment, therefore this branch line pole flexible operation is simple convenient, need not manual lock and dies, the improvement use convenience, and can keep stable when stretching out, ensure the reliability that branch line work goes on.

In the technical scheme, the pull ring 12 is fixedly arranged at the outer end of the bolt 8, and the outward pulling of the bolt 8 can be more labor-saving and convenient through the pull ring 12.

In some technical schemes, the rubber sleeve 5 is sleeved at the bottom of the loop bar 1, and the anti-slip effect can be achieved through the rubber sleeve 5, so that a worker can hold the loop bar 1 more stably and comfortably.

In the technical scheme, support 3 is fixedly arranged at the top end of inner rod 2, and the cable can be supported through support 3.

In some technical schemes, the insert 11 penetrates through the loop bar 1 and then is inserted into the tooth slot 6, and the upper part of the insert 11 is in a right-angle structure when the insert is inserted into the tooth slot 6, so that downward limiting work can be performed, and the inner bar 2 cannot be positioned in the loop bar 1 and moves downwards to shrink.

When the electric power maintenance device is used, firstly, the inner rod 2 is located in the loop bar 1 and is pulled out outwards, at the moment, the bottom of the insert 11 is designed to be an inclined plane, so that the insert 11 can be located in the tooth socket 6 and extruded, the effect can not be received when the inner rod 2 is pulled out upwards, the spring seat 10, the plug pin 8 and the insert 11 can be pushed to move leftwards through the reset spring 9, so that the insert 11 is automatically inserted into the tooth socket 6, when the insert 11 is inserted into the tooth socket 6, the upper part is in a right-angle structure, the insert 11 can play a limiting effect when the insert 11 is inserted into the tooth socket 6, the inner rod 2 is limited to be located in the loop bar 1 and is retracted downwards, and when the insert 11 is required to be retracted, the plug pin 8 and the insert 11 only need to be pulled to move rightwards through the pull ring 12, so that the insert 11 cannot play a limiting effect, then the inner rod 2 can be located in the loop bar 1, and workers can hold equipment and support cables of the equipment through the support 3 when the equipment is unfolded, so that the electric power maintenance device can be used for electric power maintenance work.
