[0001] The utility model relates to the technical field of motors, and particularly relates to a motor protection end cover with firm installation. Background Technique

[0002] As a power device widely used in industry and life, the stability and service life of a motor are directly related to the operation efficiency and safety of the device. In order to protect the key components inside the motor, end covers are usually used to encapsulate and protect the motor.

[0003] At present, the existing motor protection end covers on the market are of integral type and split type. The integral end cover is not detachable, which brings great inconvenience to maintenance and cleaning; while in some designs, only the front end or the rear end is detachable. Since the connecting parts are mostly concentrated on the edge, it is easy to cause the bolts to loosen, and it cannot effectively resist various external forces generated during the operation of the motor, and the connection is not firm. During long-term use, the vibration and thermal expansion and contraction effects generated by the operation of the motor will exacerbate these problems, resulting in the loosening of the end cover. The loosening of the end cover will cause the internal components of the motor to be exposed, increasing the risk of dust and moisture entering, and affecting the service life of the motor.

[0004] Therefore, there is an urgent need for a motor protection end cover with firm installation to solve the technical defects mentioned in the above technology. Content of the Utility Model

[0005] The purpose of the utility model is to provide a motor protection end cover with firm installation to solve the problem of the loose connection and easy detachment of the split motor end cover mentioned in the above background technique.

[0010] Furthermore, the heat dissipation component includes a negative pressure fan, the negative pressure fan is installed inside the heat dissipation component, a dust-proof net is installed outside the negative pressure fan, the dust-proof net and the heat dissipation component form a concentric circle structure, a rubber caulking is glued at the gap between the dust-proof net and the heat dissipation component, and four groups of buckle grooves are provided on the inner wall of the heat dissipation component.

[0011] Furthermore, four groups of anti-collision springs are installed at the edge of the dust-proof net, the other ends of the anti-collision springs are all welded with buckle blocks, and the buckle blocks are respectively buckled inside the buckle grooves.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The motor protection end cover with firm installation not only realizes a three-section split end cover, with a tight connection and more firm installation of the motor, reduces the problem that the connection is difficult to disassemble due to rust caused by dust and moisture, but also reduces vibration noise and improves the heat dissipation effect;

[0013] (1) By providing a front cover, a middle cover, a rear cover, a fixing tongue, a connecting page bolt, and a detachable cover, the motor protection end cover is divided into a front cover, a middle cover, and a rear cover. The three sub-covers are assembled by bolt connection. During installation, the fixing tongues at the front cover and the rear cover are respectively inserted into the inner side wall of the middle cover, and the positions of the fixing tongues are fixed by bolts on the outer wall. Then, the connecting page bolts are installed. The bolts driven from different directions make the front and rear cover bodies more tightly connected to the middle cover and will not produce relative rotation. Moreover, a detachable detachable cover is installed at the rear cover and fixed by installing bolts. The heat dissipation components are all installed at the detachable cover.
