Fig. 1 is an overall structure diagram of the present invention.
Detailed Description
The invention is further explained below with reference to the drawings:
as shown in fig. 1, the motor locked-rotor tool for the canned motor pump comprises a connecting shaft 1, a bracket 2 and a limiting rod 3; the connecting shaft 1 comprises a shaft head part 11, a connecting part 12 and a tail part 13 which are connected in sequence; the shaft head 11 is provided with a through hole 111 arranged in the radial direction; the tail part 13 is provided with an external thread; the limiting rod 3 comprises a rod body 31 and a rod head 32 connected to the end part of the rod body 31; the outer diameter of the rod head 32 is larger than the inner diameter of the through hole 111; the rod body 31 penetrates through the through hole 111; the rod head 32 is in contact with the shaft head 11; the bracket 2 comprises a bottom plate 21 and a portal frame 22; the portal frame 22 is fixed on the bottom plate 21; rubber pads 221 are mounted on the inner walls of the two sides of the portal frame 22; the limiting rod 3 penetrates through the portal frame 22; during the assembly, on the external screw thread connection who passes through afterbody 13 with connecting axle 1 to the rotor in the motor, support 2 upper plate 21 is fixed in on the flange of motor terminal surface through screw locking, wear to establish through-hole 111 and portal frame 22 of axle head portion 11 with gag lever post 3 again, guarantee that pole head portion 32 is placed up can, during the rotor of motor rotates, connecting axle 1 is along with rotating, and because gag lever post 3 pushes up and touches on the rubber pad 221 in portal frame 22, the motion of gag lever post 3 has been restricted, and then the rotation of connecting axle 1 has been restricted.
At least one side of the shaft head part 11 corresponding to the through hole 111 is provided with a plane 112, and the rod head part 32 is directly abutted against the plane 112 of the shaft head part 11, so that the stability is high.
The two planes 112 are symmetrically arranged on the front side and the rear side of the shaft head part 11, and the planes 112 are arranged on the two sides, so that the assembly is convenient.
