[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4 , a DC motor with noise reduction function, comprising a DC motor base 1, on which a DC motor 2 is placed;

[0020] It also includes an iron column 100, and the four corners of the top surface of the iron column 100 are fixedly connected with connecting plates 3, and two connecting plates 3 are commonly fixedly connected with fixing rods 4, and the fixing rods 4 are sleeved into the through holes 50 of the sound insulation screen 1 5.

[0021] The utility model further comprises a second sound insulation screen 6 , wherein the second sound insulation screen 6 is penetrated by a through hole 50 , and the through hole 50 of the first sound insulation screen 5 is sleeved into the fixing rod 4 .

[0022] In the utility model, grooves 52 are provided on the corresponding sides of the sound insulation screen 1 5 and the sound insulation screen 2 6, and semicircular holes 51 are provided on the sound insulation screen 1 5 and the sound insulation screen 2 6. The two semicircular holes 51 together form a circle. The diameter of the two semicircular holes 51 is larger than the diameter of the rotating shaft of the DC motor 2. This is mainly to facilitate the opening of the sound insulation screen 1 5 and the sound insulation screen 2 6 to avoid the semicircular holes 51 hitting the rotating shaft. At the same time, the two semicircular holes 51 can also play a heat dissipation effect. The rotating shaft of the DC motor 2 passes through the two semicircular holes 51.

[0023] In the utility model, the sound insulation screen 1 5 and the sound insulation screen 2 6 are both embedded with magnetic strips 7 , and the magnetic strips 7 are magnetically connected to the iron pillars 100 .

[0024] In the utility model, as shown in the accompanying drawings of the specification Figure 1 As shown, in order to facilitate the heat dissipation of the DC motor 2, the sound insulation screen 1 5 and the sound insulation screen 2 6 are arranged at one-third of the DC motor 2, and the DC motor 2 is externally connected to a power supply.

[0025] The use method and advantages of the utility model: When the DC motor with noise reduction function is used, the working process is as follows:

[0026] As shown in the attached figure of the instruction manual Figure 1As shown, the soundproof screen 1 5 and the soundproof screen 2 6 are arranged on the iron column 100, and the four sides of the DC motor base 1 are hollowed out, mainly to facilitate the DC motor 2 to have a certain heat dissipation effect in the working state, that is, to avoid the soundproof screen in the fully enclosed state covering the DC motor 2, that is, to reduce the problem of reduced service life of the DC motor 2;

[0027] When the DC motor 2 needs to be repaired or installed, the user only needs to hold the pull groove 52 with both hands and rotate the sound insulation screen 1 5 and the sound insulation screen 2 6 to both sides. At this time, the sound insulation screen 1 5 and the sound insulation screen 2 6 are restricted by the fixing rod 4 and rotate around the fixing rod 4, and then place it horizontally as shown in the figure of the specification. Figure 2 After the inspection is completed, the user rotates the sound insulation screen 1 5 and the sound insulation screen 2 6 to the center direction to reset, as shown in the figure of the specification. Figure 1 In the state shown, the magnetic strips 7 on the sound insulation screen 1 5 and the sound insulation screen 2 6 will attract the iron column 100, so as to limit the positions of the sound insulation screen 1 5, the sound insulation screen 2 6 and the iron column 100. By dividing the sound insulation screen into two, on the one hand, a good noise reduction effect is achieved. On the other hand, the sound insulation screen is installed on the DC motor base 1 to make it an integrated structure, which avoids the trouble of looking for a sound insulation screen to reduce the noise of the DC motor 2 after it generates noise; at the same time, by turning over the sound insulation screen 1 5 and the sound insulation screen 2 6 to spread and cover them, it is convenient for users to repair the DC motor 2.
