Description

Technical Field

[0001] The utility model relates to the technical field of motor end covers, in particular to an end cover structure of a motor. Background Art

[0002] The motor end cover is one of the important components of the motor. It is usually located at both ends of the motor. It can effectively protect the rotor, stator and other key components inside the motor from damage by the external environment and extend the service life of the motor.

[0003] However, it still has the following disadvantages in actual use:

[0004] The end cover structure of the existing motor is generally connected to the motor body by a threaded connection. However, after the end cover is connected to the motor body, it is directly placed on the ground through the base at the lower end of the motor body. There is a lack of anti-theft protection measures, which increases the risk of loss. Utility Model Content

[0005] Technical issues to be solved

[0006] The purpose of the utility model is to provide an end cover structure of an electric motor to solve the problem raised in the above-mentioned background technology that the end cover structure of the existing electric motor is generally connected to the motor body by a threaded connection method, but after the end cover is connected to the motor body, it is directly placed on the ground through the base at the lower end of the motor body, lacks anti-theft protection measures, and increases the risk of loss.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is an end cover structure of a motor, comprising:

[0009] The end cover portion comprises a rear cover plate and a front cover plate connected to the front end of the rear cover plate;

[0010] The locking part includes positioning grooves equidistantly arranged on the front surface of the outer surface of the front cover plate;

[0011] The anti-theft part includes a top plate arranged just below the front cover plate, a bottom plate arranged below the top plate, and a pressure sensor whose ends are respectively connected to the top plate and the inner side of the bottom plate.

[0012] Furthermore, screw holes are equidistantly penetrated through the outer edges of the top plate and the bottom plate, and the diameter of the bottom plate is twice the diameter of the top plate;

[0013] Specifically, the screw holes can receive bolts for structurally fastening the entire anti-theft portion, and the diameter of the bottom plate is twice the diameter of the top plate, so as to increase the contact surface and improve the stability of the structure.

[0014] Furthermore, an anti-theft rope is connected to the middle of the outer end of the top plate;

[0015] Specifically, the anti-theft rope connects the top plate and the plug, so that when the motor body is moved by humans, the pressure sensor can be linked to operate, and an early warning alarm can be performed through an external early warning device, thereby achieving an anti-theft effect.

[0016] Furthermore, the end cover portion further comprises a plurality of metal heat sinks equidistantly connected to the outer surface of the front cover plate and threads equidistantly arranged at the front and rear ends of the inner surface of the front cover plate;

[0017] Specifically, the metal heat sink can be used for heat dissipation and can facilitate the convenient control of the front cover structure to facilitate the application of force required for disassembly and assembly, while the arrangement of the threads satisfies the connection and fixation between the front cover, the rear cover and the motor body.

[0018] Furthermore, the middle part of the front cover plate is a cavity that penetrates through and is connected to the rear cover plate through the thread at the rear end;

[0019] Specifically, the cavity receives the rear end of the external motor body, and the threaded connection method fixes the front cover plate and the rear cover plate, which can facilitate the subsequent disassembly and assembly of the structure.

[0020] Furthermore, a plug is connected to the middle of the rear end of the rear cover plate, and the outer end of the plug is connected to one end of the anti-theft rope;

[0021] Annular grooves are arranged equidistantly inside the rear cover plate and the front cover plate;

[0022] Specifically, the opening and closing of the plug can be used to inject and discharge cooling water in the annular groove, so as to cooperate with the above-mentioned metal heat sink to further improve the heat dissipation effect.

[0023] Furthermore, the locking portion further includes a screw pipe penetrating through the positioning groove;

[0024] The spiral tube is connected to the corresponding slot in the positioning slot through the clamping blocks arranged at equal distances on the outer edge;

[0025] Specifically, the connection between the card block and the card slot fixes the screw tube structure, and the screw tube is connected to the bolt, so that multiple adjacent unused front cover plates can be centrally limited and fixed. The detachable design of the screw tube avoids the disadvantage of difficulty in continuing operation after the bolt is stripped or broken in the screw tube. Beneficial Effects

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] The utility model is provided with a pressure sensor, and the end cover part is connected to the external motor body. When the motor body is moved manually, force acts on the anti-theft rope, and as the motor body gradually leaves the ground, the anti-theft rope exerts an upward pulling force on the pressure sensor, and the force on the pressure sensor changes. An externally controlled alarm can be used for early warning, thereby achieving an anti-theft effect, reducing the probability of loss and saving costs.

[0028] Based on the first beneficial effect, a screw tube is provided on the front cover plate included in the end cover part, and is fixed by a clip-on connection method. The screw tube can be used in conjunction with an external long bolt to perform structural positioning on a group of adjacent front cover plates when not in use, which is beneficial for subsequent placement and storage and reduces the probability of loss. The clip-on connection method avoids the disadvantage that it is difficult to handle immediately after the bolt is stripped or broken in the screw tube.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Screw holes are evenly spaced through the outer edges of the top plate 31 and the bottom plate 33, and the diameter of the bottom plate 33 is twice the diameter of the top plate 31;

[0046] An anti-theft rope 34 is connected to the middle of the outer end of the top plate 31;

[0047] How to use the anti-theft department, publish the following steps:

[0048] After the end of the anti-theft rope 34 is sequentially connected with the plug 15 and the top plate 31 to perform structural locking;

[0049] At this time, the upper and lower ends of the pressure sensor 32 are connected to the inner sides of the top plate 31 and the bottom plate 33 respectively, and the bottom plate 33 is placed below the front cover plate 12, and the bottom plate 33 can be fixed by inserting bolts into the screw holes and screwing them in.

[0050] When the motor body is subsequently moved manually, the anti-theft rope 34 is gradually moved upward, and the anti-theft rope 34 in the upward movement exerts force on the pressure sensor 32. The pressure sensor 32 after being stressed transmits a data signal to the external control end, so as to warn against theft through the external alarm.

[0051] This step can prevent theft, reduce the probability of loss and save costs. Example

[0059] Next, the external long bolts are sequentially passed through the screw tubes 22 provided on the multiple front cover plates 12, and the multiple front cover plates 12 placed side by side are centrally limited in structure, and then they are centrally stored and placed;

[0060] This step can improve the applicability and functionality of the structure, and the detachable screw tube 22 can avoid the disadvantages of subsequent thread slippage and breakage compared to directly using screw holes.
