Description

Technical Field

[0001] The utility model relates to the technical field of motor housings, in particular to a novel plastic motor housing. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. As a power source for electrical appliances or various machines, its main function is to convert electrical energy into mechanical energy. However, the existing motor housing provides a positioning and supporting function for the motor. Most common motor housings are made of metal materials (such as iron, iron and aluminum). The motor housing includes a casing and an end cover. Since the winding end cannot directly contact the metal end cover, the metal end cover needs to be made higher, and the insulation problem between the winding and the metal end cover needs to be considered.

[0003] To solve the above problems, there are also plastic motor housings in the prior art, including a casing and an end cover. Windings and the like are placed inside the casing, and the casing and the end cover are fixedly connected by rivets or adhesives, which are extremely difficult to disassemble. When the motor fails, it is inconvenient to disassemble the end cover for maintenance operations, and there is a problem of difficult maintenance. Summary of the Utility Model

The return springs are all sleeved on the outer sides of the pull rods and are located between the sliders and the inner walls of the L-shaped grooves. The clamping pieces are equiangularly fixedly connected to one side of the motor rear cover. The clamping grooves are all opened on the outer sides of the clamping pieces. The clamping grooves are all used in cooperation with one end of the pull rod.

[0007] The device is placed at the specified position through the fixing holes. The motor coil to be fixed is installed inside the motor housing, and then parts such as the motor are installed. The motor rear cover inserts the clamping part into one side of the corresponding L-shaped groove. When the clamping part enters the inside of the L-shaped groove, the arc on one side causes the pull rod to move outward. The return spring cooperates with the slider to drive the pull rod to reset. One end of the pull rod enters the inside of the clamping groove to fix the motor rear cover. At the same time, the fixing plate fixes the motor coil. The material of the device is plastic, which has high strength and good durability. When the end cover needs to be disassembled, only need to dial the pull rod outward so that one end of the pull rod disengages from the clamping groove, and the fixation of the clamping component can be released, that is, the motor rear cover can be removed from the housing, making the maintenance operation more convenient and simple, which is beneficial to practical application and operation.

[0008] In a preferred embodiment, the slider is slidably connected to one side of the L-shaped groove in a restricted manner, and one ends of the pull rod and the clamping part are both arc-shaped.

The slider is slidably connected to one side of the L-shaped groove in a restricted manner to prevent the clamping part from colliding with the slider.

[0010] In a preferred embodiment, mounting grooves are equally angled on the inner wall of the motor housing, and fixing plates are equally angled and fixedly connected to the inner wall of the motor rear cover. The fixing plates and the mounting grooves are both used in cooperation with the motor coil to be fixed.

[0011] By setting the mounting grooves, it is beneficial to install the coil to be fixed, and it is convenient to fix the coil by using the fixing plates.

[0012] In a preferred embodiment, strengthening blocks are fixedly connected to both ends of the top of the bottom plate, and the strengthening blocks are both fixedly connected to the outside of the motor housing. Fixing holes are provided at the four corners of the bottom plate.

[0013] By setting the strengthening blocks, it helps to increase the stability of the fixation between the bottom plate and the motor housing, and the bottom plate is installed by using the fixing holes.

[0014] In a preferred embodiment, both the motor housing and the motor rear cover are made of plastic material.

[0015] By setting, using this plastic material can avoid the motor generating static electricity, thereby avoiding the phenomenon of electric shock to workers, and at the same time has good heat dissipation, protection and sound insulation effects.

[0016] In a preferred embodiment, a number of through holes are equidistantly provided on the outside of the motor rear cover.

[0017] By setting, the through holes are used to dissipate heat from the motor inside the motor housing.

[0018] The novel plastic motor housing provided by the utility model has the following advantages:

[0019] This device is set to place the device at a designated position through the fixing holes, install the motor coil to be fixed inside the motor housing, and then install parts such as the motor. Insert the clamping part of the motor rear cover into one side of the corresponding L-shaped groove. When the clamping part enters the inside of the L-shaped groove, the arc on one side causes the pull rod to move outward. The return spring cooperates with the slider to drive the pull rod to reset. One end of the pull rod enters the inside of the clamping groove to fix the motor rear cover. At the same time, the fixing plate fixes the motor coil. The material of this device is plastic, with high strength and good durability. When the end cover needs to be disassembled, only need to dial the pull rod outward so that one end of the pull rod disengages from the clamping groove, then the fixation of the clamping component can be released, and the motor rear cover can be removed from the casing, making the maintenance operation relatively convenient and simple, which is beneficial to actual application and operation.
