[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0020] First, combine Figures 1 to 3 A rotor with anti-loosening pin bolts according to an embodiment of the utility model is described, which is used to prevent the pin bolts 3 in the rotor from loosening and has a wide range of application scenarios.

[0021] like Figures 1 to 3 As shown, a rotor with pin bolts to prevent loosening in an embodiment of the utility model comprises: a rotor core 1, a pair of rotor sleeves 2, and six pin bolts 3. The pair of rotor sleeves 2 are symmetrically arranged on both sides of the rotor core 1. Any rotor sleeve 2 is fixed to the rotor core 1 by three pin bolts 3. The three pin bolts 3 on the pair of rotor sleeves 2 are arranged oppositely; it also comprises: three through holes 4, welding holes 5, and three anti-loosening parts 6. The three through holes 4 are provided on the rotor core 1; the welding holes 5 are provided on any pin bolt 3; the anti-loosening part 6 is a metal rod, any anti-loosening part 6 passes through any through hole 4, and the two ends of any anti-loosening part 6 are respectively inserted into the welding holes 5 of any two oppositely arranged pin bolts 3 and welded together, so as to effectively prevent the rotor from loosening when the pin bolts 3 are in use.

[0022] Furthermore, in this embodiment, the rotor sleeve 2 is made of polytetrafluoroethylene material, which can be used to transport materials in special scenarios.

[0023] Further, if Figure 2~3As shown, three positioning protrusions 71 are provided on both sides of the rotor core 1, and three positioning grooves 72 are provided on the rotor sleeve 2. The shapes of the positioning protrusions 71 and the positioning grooves 72 match each other to ensure accurate assembly.

[0025] Furthermore, three recessed grooves 8 are provided on the surface of any rotor sleeve 2 , and the pin bolts 3 are located in the recessed grooves 8 and do not protrude from the surface of the rotor sleeve 2 , thereby preventing the pin bolts 3 from interfering with each other.

[0026] Further, if Figure 2~3 As shown, three positioning pins 91 are provided on both sides of the rotor core 1, and three positioning holes 92 are provided on the rotor sleeve 2. The positioning pins 91 match the positioning holes 92 in shape, and secondary positioning is performed to further improve assembly accuracy.

[0027] During installation, the anti-loosening member 6 is passed through the through hole 4, and the two ends of the anti-loosening member 6 are respectively welded to the two oppositely arranged pin bolts 3, thereby completing all the assembly. If the rotor sleeve 2 needs to be replaced later, the welding positions at both ends are milled off with an electric drill, and the pin bolts 3 can be loosened.

[0028] As described above, according to a rotor with pin bolts to prevent loosening according to an embodiment of the utility model, a pair of pin bolts 3 on the rotor sleeve 2 are welded at both ends of the anti-loosening member 6, so that the pin bolts 3 can be effectively fixed to prevent loosening.

[0029] According to another embodiment of the utility model, a rotor pump is provided, comprising a rotor with anti-loosening pin bolts of the previous embodiment, which effectively prevents the pin bolts 3 from loosening and ensures the stability of the rotor sleeve 2, thereby allowing the rotor pump to operate effectively.
