[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3 As shown, the utility model provides a new type of motor end cover structure, including a motor end cover body 1, a dust cover 2, a clamping block 3 and a clamping slot 4, the left side of the clamping block 3 is fixedly connected to the right side of the dust cover 2, the clamping slot 4 is opened on the left side of the motor end cover body 1, the clamping slot 4 is plugged into the clamping block 3, a threaded hole 5 is opened on the outer side of the clamping block 3, the threaded hole 5 is opened to the surface of the motor end cover body 1, the inner wall of the threaded hole 5 is threadedly connected with a bolt 6, and the left side of the dust cover 2 is fixedly connected with an auxiliary reinforcement component 7.

[0022] refer to Figures 1 to 3 The auxiliary reinforcement component 7 includes a reinforcement iron ring 71, two reinforcement iron rings 71 are provided and have different sizes. A reinforcement connecting plate 72 is provided on the front of the dust cover 2, and the outer side and the inner side of the right side of the reinforcement connecting plate 72 are fixedly connected to the left side of the reinforcement iron ring 71.

[0023] As a technical optimization scheme of the utility model, by setting up an auxiliary reinforcement component 7, the user can use the reinforcement iron ring 71 to perform annular reinforcement on the dust cover 2, and then use the reinforcement connecting plate 72 to perform auxiliary reinforcement between the two reinforcement iron rings 71, thereby further improving the reinforcement effect of the dust cover 2.

[0024] refer to Figures 1 to 3 The top of the left side of the dust cover 2 is fixedly connected with an anti-lost rope 8, and the material of the anti-lost rope 8 is nylon.

[0025] As a technical optimization scheme of the utility model, an anti-loss rope 8 is provided, so that the user can place the dust cover 2 at will after removing the dust cover 2, and the dust cover 2 can be prevented from being lost under the action of the anti-loss rope 8. The advantages of nylon's strong toughness and wear resistance are utilized to improve the service life and use effect of the anti-loss rope 8.

[0026] refer to Figures 1 to 3 One end of the anti-lost rope 8 away from the dust cover 2 is fixedly connected with a screw rod 9, and the surface of the screw rod 9 is threadedly connected with a screw sleeve 10, and the bottom of the screw sleeve 10 is fixedly connected to the top of the motor end cover body 1.

[0027] As a technical optimization scheme of the utility model, by providing the screw 9 and the screw sleeve 10, when the dust cover 2 is damaged after long-term use, the user can rotate the screw 9 to make the screw 9 rotate and move upward until the screw 9 is no longer threadedly connected with the screw sleeve 10, and then one end of the anti-lost rope 8 is unfixed, thereby facilitating the user to replace the dust cover 2.

[0028] refer to Figures 1 to 3 Both sides of the top of the screw rod 9 are fixedly connected with force rods 11, and the material of the force rods 11 is PP plastic.

[0029] As a technical optimization solution of the utility model, by setting the force rod 11, when the user needs to rotate the screw 9, the user can rotate it by buckling the two force rods 11, and then the force rod 11 mobilizes the screw 9 to rotate, thereby giving the user a point of force for applying force, and then taking advantage of the low cost of PP plastic, the user's use cost is reduced.

[0030] refer to Figures 1 to 3 A knob 12 is fixedly connected to the top of the bolt 6, and the knob 12 is arranged in a cross shape.

[0031] As a technical optimization solution of the utility model, by setting the knob 12, when the user needs to rotate the bolt 6, the user can apply force by buckling the cross-shaped knob 12, thereby providing the user with a point of force for the bolt 6.

[0032] The working principle and usage process of the utility model are as follows: when the user needs to connect the motor end cover body 1 with the dust cover 2, the user first plugs the block 3 on the dust cover 2 into the slot 4, and then the user can insert the bolt 6 into the threaded hole 5, and then the user rotates the bolt 6 to make the bolt 6 rotate and move inward, and then the bolt 6 can be threadedly connected with the threaded hole 5. At this time, the block 3 is limited to the left and right, thereby preventing the dust cover 2 from falling off, and then the reinforcing iron ring 71 can be used to perform annular reinforcement on the dust cover 2, and then the reinforcing connecting plate 72 can be used to perform auxiliary reinforcement between the two reinforcing iron rings 71, thereby further improving the reinforcement effect of the dust cover 2, and having the ability to improve the fixing effect of the dust cover 2.

[0033] To sum up: the new motor end cover structure, by setting a threaded hole 5 and a bolt 6, rotates the bolt 6 to make the bolt 6 rotate and move inward, and then the bolt 6 can be threadedly connected with the threaded hole 5. At this time, the block 3 is limited to the left and right, thereby preventing the dust cover 2 from falling off, and solves the problem of poor connection strength between the dust cover and the end cover body. The dust cover may fall off easily due to the connection between the card slot and the card block alone, and the dust cover 2 is not strong enough and is easily damaged by collision with foreign objects.
