[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] Some embodiments of the utility model are described below in conjunction with the accompanying drawings to provide a motor end cover with adjustable heat dissipation. Embodiment 1

[0022] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a motor end cover with adjustable heat dissipation, including an end cover body 100, an adjustment assembly 200 and a mounting ear 300.

[0023] Specifically, a heat dissipation hole 110 is opened on the end cover body 100, and there are two heat dissipation holes 110. Both heat dissipation holes 110 can dissipate heat and ventilation for easy use. A protective net 120 is provided on the inner wall of the heat dissipation hole 110. The protective net 120 has a certain dust-proof effect and also has a protective effect. Three card blocks 130 are provided on the outer side of the end cover body 100, and the three card blocks 130 are distributed in a circle.

[0024] Specifically, the adjustment component 200 includes a screw 210 that passes through the end cover body 100, a baffle 220 arranged on the left side of the screw 210, a brush 230 arranged on the right side of the baffle 220, and a fastening knob 240 threadedly connected to the screw 210. A rotating plate 250 is arranged on the right side of the screw 210. When in use, the fastening knob 240 can be loosened. After loosening, the screw 210 and the baffle 220 can be rotated by the rotating plate 250. The rotating baffle 220 can block the heat dissipation hole 110. After blocking a part, the fastening knob 240 can be tightened to adjust the size of the heat dissipation hole 110 for use. When the baffle 220 completely blocks the heat dissipation hole 110, it can play a sealing and dust-proof effect for storage. When the baffle 220 rotates, it will drive the brush 230. Since the brush 230 can rub against the protective net 120, the principle of friction can be used to clean the protective net 120 to prevent dust from hindering the heat dissipation effect for use.

[0025] Specifically, the three mounting ears 300 are all arranged on the outside of the end cover body 100, and the three mounting ears 300 are all provided with a slot 310. The three mounting ears 300 are all connected to the block 130 through the slot 310. When in use, the slot 310 of the mounting ear 300 can be aligned with the block 130 outside the end cover body 100 and snap-fitted, so that the mounting ear 300 can be fixed to the end cover body 100. After fixation, the mounting ear 300 can be fixed to the motor by screws, thereby achieving the effect of a detachable mounting ear 300, so as to facilitate replacement of the mounting ear 300.

[0026] The working principle and use process of the utility model are as follows: when in use, the fastening knob 240 of the adjustment component 200 can be loosened, and after loosening, the baffle 220 can be rotated by the rotating plate 250 and the screw 210, and the rotating baffle 220 can block the heat dissipation hole 110. After blocking a part, the fastening knob 240 can be tightened to adjust the size of the heat dissipation hole 110 for use. When the baffle 220 completely blocks the heat dissipation hole 110, it can play a sealing and dust-proof effect for storage, and when the baffle 220 rotates, it will drive the brush wire 230. Since the brush wire 230 can rub against the protective net 120, the principle of friction can be used to clean the protective net 120 to prevent dust from hindering the heat dissipation effect for use. Afterwards, the card slot 310 of the mounting ear 300 can be aligned with the card block 130 outside the end cover body 100 and clamped. After clamping, the mounting ear 300 can be fixed on the motor by screws to achieve the effect of detachable mounting ear 300, so as to replace the mounting ear 300.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
