[0002] An electric motor is a component that can convert electrical energy into mechanical energy. It can be divided into DC motors and AC motors according to the power source used. Currently, most of the motors in the power system are AC motors, which are the most widely used mechanical components in mechanical equipment.

[0003] Most motors are fixedly installed by bolts (mounting base with mounting holes), but the existing motor mounting structure has a fixed single position, and the mounting base is usually welded to the bottom of the motor, or the mounting base is welded to one side of the motor. It is impossible to select a suitable installation position and direction according to the actual installation situation, and the flexibility and anti-interference ability are low.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] Preferably, the anti-vibration support foot includes a groove located below the arc plate, and the inner walls of the two grooves that are close to each other are fixedly installed with a first shock absorber, the bottom surfaces of the movable ends of the two first shock absorbers are fixedly installed with a second shock absorber, and the bottom ends of the second shock absorbers are fixedly connected to a long mounting plate.

[0009] Preferably, a clamping friction plate is connected between the two second shock absorber fixed ends, and the bottom end of the clamping friction plate is welded to the top surface of the elongated mounting plate.

[0010] Preferably, the ends of the two bidirectional screws that are away from each other are each provided with an adjusting knob, and the adjusting knob is wrapped with a matching rubber anti-slip sleeve.

[0011] Preferably, there are four pairs of threaded knobs, and each pair of threaded knobs is distributed in a ring shape.

[0012] Preferably, the threaded knob comprises a locking knob, an end of the locking knob close to the motor body is integrally connected with a stud, and an end of the stud close to the motor body is integrally connected with a round table.

[0013] The beneficial effects of the utility model are:

[0014] 1. By setting up annular slide rails, arc pieces and threaded knobs, the anti-seismic support feet can be distributed in multiple positions, so that the motor can be fixedly installed on four surfaces (bottom surface, top surface, and two side surfaces), and the installation range is greatly improved. At the same time, no matter which surface it is installed on, the anti-seismic support feet can play a good shock absorption and buffering performance, and the use effect is good;

The two annular slide rails 4 are provided with arc plates 5 slidably connected thereto, and the bottom ends of the two arc plates 5 are installed with anti-vibration support feet. The two annular slide rails 4 are threadedly connected to the sides away from each other with multiple pairs of threaded knobs 7, which play a role in tightening the arc plates 5. The position of the arc plates 5 can be flexibly adjusted, and a suitable installation surface can be selected according to actual conditions, and the installation range is greatly improved. An extended convex plate 8 is welded at the bottom end of the motor body 1, and a bidirectional screw 9 is provided on the front side of the extended convex plate 8 to penetrate to its rear end. The bidirectional screw 9 is rotatably connected to the extended convex plate 8, and the bidirectional screw 9 is threadedly connected to a pair of connecting plates 10, and the two connecting plates 10 are respectively welded to the two reinforcement bars 3.

[0028] Embodiment 2:

[0029] like Figure 1-5As shown, according to the seismic motor of the embodiment of the utility model, the seismic support foot includes a groove 11 located below the arc piece 5, and the inner wall of the side where the two grooves 11 are close to each other is fixedly installed with a first shock absorber 12, and the bottom surface of the movable end of the two first shock absorbers 12 is fixedly installed with a second shock absorber 13. The first shock absorber 12 is the same as the second shock absorber 13, and both are existing spring shock absorbers, mainly composed of a spring and a damper, with good shock absorption and good anti-seismic effect. The bottom end of the second shock absorber 13 is fixedly connected with an elongated mounting plate 14, which can play a good shock absorption and buffering role when installed vertically, and can also provide good shock absorption and buffering effect when installed horizontally, with high use effect and flexibility. A clamping friction plate 15 is connected between the fixed ends of the two second shock absorbers 13, and the bottom end of the clamping friction plate 15 is welded to the top surface of the elongated mounting plate 14. When there is no mounting hole on the mounting surface, it can be changed to another mounting method to still achieve the fixed mounting function of the motor.

[0030] Embodiment three;

[0031] like Figure 1-5 As shown, according to the earthquake-resistant motor of the embodiment of the utility model, the two bidirectional screws 9 are provided with an adjusting knob 16 at one end away from each other, and the adjusting knob 16 is wrapped with a rubber anti-slip sleeve matching it. Both the front and rear ends can conveniently drive the bidirectional screw 9 to rotate, and the operation is simple and quick.

[0032] Embodiment 4:

[0033] like Figure 1-5 As shown, according to the earthquake-resistant motor of the embodiment of the utility model, there are four pairs of threaded knobs 7, and each pair of threaded knobs 7 is distributed in a ring shape.
