In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of insulator crossarm,
Including main body, reinforcement and felt pad, the main body is hollow rectangle tube, and the top surface of main body and bottom surface are respectively equipped with
Felt pad, the top surface of main body and bottom surface are provided with the mounting hole of fixed insulator pad, on the opposite face of body interior left and right sides wall
T-shaped groove is provided with, along the axially arranged of main body, the reinforcement is fixed in T-shaped groove the T-shaped groove.
Preferably, along the axially in parallel arrangement of main body, mounting hole is circular port or mounting hole to the mounting hole.Different shape
Mounting hole be used for various sizes of insulator is installed, it is widely applicable.
Preferably, felt pad includes fixing pad and projection, and projection is fixed on the fixed face padded with body contact, described convex
The shape for rising matches with mounting hole, and the fixed pad left and right sides is provided with the first arc angling.Felt pad can increase insulator with
Insulating properties between main body；First arc angling increases aesthetic property；It is raised to play positioning action when felt pad is installed.
Preferably, it is provided with location hole in the projection.Location hole plays positioning action when insulator is installed.
Preferably, the reinforcement includes the first cross bar, the second cross bar and connecting rod, and the first cross bar and the second cross bar pass through
Connecting rod is connected, and the length of the first cross bar is the half of the second cross bar.Reinforcement is for I-shaped, and the length of the first cross bar is the
The half of two cross bars, is easily installed, and effect resistant to bending is good.
Preferably, the first cross bar and connecting rod are in T-shaped groove, and the second cross bar is fixed with main body wall inner surface.Plus
The contact surface of strong muscle and main body increases, and counter-bending effect is more preferable；Second cross bar is fixed in main body wall inner surface, tears reinforcement open
Dress is more convenient.
Preferably, four chamferings in main body inner side are the second arc angling.The design of the second arc angling reduces main body
Point discharge.
Compared with prior art, the utility model has the advantages that：Main body upper and lower end face is provided with felt pad, and felt pad not only increases
Add the insulating properties between main body and insulated terminal, and protect body surfaces not to be scraped off；Body interior left and right sides wall
T-shaped groove is provided with opposite face, T-shaped groove significantly increases the mechanical performance of main body, increased main body built with reinforcement
Flexural strength.
