[0006] Further, the protective frame is a rectangular frame, including a bottom frame, a protective cover, and an opening and closing cylinder. One side of the bottom frame is provided with a vertically arranged mounting beam. The protective cover is hinged to the bottom frame. The opening and closing cylinder is hinged to the mounting beam, and the cylinder rod of the opening and closing cylinder is hinged to the protective cover.

[0007] Further, the bottom frame is formed by fixing a plurality of cross beams, longitudinal beams, and vertical beams.

[0008] Further, the support base includes a base, an adjusting beam, and a support beam. The adjusting beam is arranged vertically, with its bottom end fixed to the base and its top end fixed to the support beam. The base is fixed to the protective frame.

[0009] Further, the base is a U-shaped seat.

[0010] Further, the adjusting beam includes a sub-beam, a mother beam, and a locking bolt. The sub-beam is inserted into the mother beam. A plurality of vertically arranged screw holes are provided on both the sub-beam and the mother beam. The locking bolt passes through the mother beam and into the screw hole of the sub-beam.

[0011] Further, a flange seat is fixed on the outer wall of the cylinder.

[0012] The utility model has the following beneficial effects:

[0013] The structure of the utility model is simple. It is used for the bending test of post insulators and is safer to use. After use, the bolts between the flange seat and the protective frame are removed, and then the mobile cart is moved away to prevent the cylinder from occupying a large space on one side of the protective frame.

[0018] The following further describes the utility model with reference to the drawings.

[0019] As Figures 1 to 4 , a bending test device for an insulator of the utility model includes a support seat 1, a cylinder 2, a mobile cart 3, and a protective frame 4. A plurality of support seats 1 are fixed inside the protective frame 4. Two cylinders 2 are fixed on two mobile carts 3. The two cylinders 2 are arranged symmetrically in opposite directions on both sides of the protective frame 4, and each cylinder is fixed to the protective frame 4.

[0020] During use, the post insulator is horizontally supported on the support seat 1. The two cylinders are arranged symmetrically in opposite directions on both sides of the post insulator, and then the two cylinders simultaneously press against the post insulator, thereby realizing the bending test of the post insulator. After use, the cylinders are removed without occupying space.

[0021] The protective frame 4 in the utility model is a rectangular frame, including a bottom frame 41, a protective cover 42, and an opening and closing cylinder 43. The bottom frame 41 is formed by fixing a plurality of cross beams, longitudinal beams, and vertical beams. There is a vertically arranged mounting beam 44 on one side of the bottom frame 41. The protective cover 42 is hinged to the bottom frame 41. The opening and closing cylinder 43 is hinged to the mounting beam 44, and the cylinder rod of the opening and closing cylinder 43 is hinged to the protective cover 42.

[0022] The support seat 1 includes a base 11, an adjustment beam 12, and a support beam 13. The base 11 is a U-shaped seat and is fixed to the cross beam or longitudinal beam in the protective frame 4 by bolts. The adjustment beam 12 is arranged vertically, with the bottom end fixed to the base 11 and the top end fixed to the support beam 13.

[0023] The height of the adjusting beam 12 is adjustable to be applicable to the post insulators of different pipe fittings. It includes a sub-beam, a mother-beam and a locking bolt. The sub-beam is inserted into the mother-beam. A number of vertically arranged screw holes are provided on both the sub-beam and the mother-beam, and the locking bolt passes through the mother-beam and into the screw hole of the sub-beam.

[0024] When the cylinder shaft extends and abuts against the post insulator, to prevent the reverse force from pushing away the mobile cart 3, in the present utility model, a flange seat 21 is fixed on the outer wall of the cylinder 2, and the cylinder is fixed to the protective frame 4 through the flange seat to prevent the cylinder from being pushed away and displaced in the reverse direction.

[0025] After the present utility model is used up, the bolts between the flange seat and the protective frame 4 are removed, and then the mobile cart 3 is removed to prevent the cylinder from occupying a large space on one side of the protective frame.

[0026] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be regarded as the protection scope of the present utility model.
