[0003] The existing patent document with announcement number CN219893062U discloses a motor housing that is easy to disassemble, including an upper shell, a lower shell, an upper connecting plate and a lower connecting plate. One side of the upper shell is fixedly connected to the upper connecting plate, and one side of the lower shell is fixedly connected to the lower connecting plate. A limiting pin passes through the upper connecting plate to connect the lower connecting plate, and a limiting groove and a rotating cavity are arranged inside the lower connecting plate.

[0004] However, the above device has the following problems when in use:

[0005] When the device is disassembled, the upper shell, lower shell, limit pins and other parts need to be separated from each other, small parts are easy to lose, and subsequent installation requires manual alignment of the holes on the upper shell and the lower shell before assembly can be carried out, which is inefficient.

[0006] Therefore, we propose a motor housing that is easy to disassemble to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a motor housing that is easy to disassemble. A sliding connection is adopted between the upper shell and the lower shell, so that a connection relationship still exists between the upper shell and the lower shell after disassembly. After subsequent maintenance is completed, it is only necessary to push the upper fixing plate to restore the upper shell to its original position, so that the upper shell and the lower shell can be quickly and initially installed.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] See also Figures 1 to 10A motor housing that is easy to disassemble includes an upper shell 1 and a lower shell 2. An upper fixing plate 5 and a lower fixing plate 6 are fixedly installed on the upper shell 1 and the lower shell 2 respectively. In order to protect the tightness of the connection between the upper shell 1 and the lower shell 2, a sealing gasket can be laid between the upper fixing plate 5 and the lower fixing plate 6, and a tight connection is achieved by squeezing the sealing gasket.

[0034] A slider 9 is fixedly mounted on the upper fixed plate 5, and a slide groove 7 for the slider 9 to slide is provided on the lower fixed plate 6;

[0035] The slider 9 can move inside the slide groove 7, thereby driving the upper fixing plate 5 to be displaced, so that the upper shell 1 moves synchronously, and the space inside the motor can be exposed to facilitate maintenance activities. Since the length of the lower fixing plate 6 is greater than the length of the upper fixing plate 5, the upper shell 1 will not fall when it is pulled out. The upper shell 1 will be on the extended end of the lower fixing plate 6, so that the upper shell 1 and the lower shell 2 are still connected together. After the subsequent maintenance is completed, it is only necessary to push the upper fixing plate 5 to restore the upper fixing plate 5 to its original position, so as to achieve a quick preliminary installation of the upper shell 1 and the lower shell 2.

[0036] A lifting plate 14 is slidably mounted inside the upper fixed plate 5, a spring 15 is fixedly mounted on the lifting plate 14, the other end of the spring 15 is fixedly mounted on the upper fixed plate 5, and an operating rod 8 is arranged on the lifting plate 14;

[0037] The installation rod 12 is evenly and rotatably installed on one end of the lifting plate 14 away from the operating rod 8 , and a limiting hole 17 for accommodating the installation rod 12 is opened at a corresponding position of the lower fixing plate 6 .

[0038] The presence of the spring 15 ensures that the lifting plate 14 is in a lower position when no external force is applied. At this time, the mounting rod 12 is inside the limiting hole 17, and the upper fixing plate 5 cannot move, thereby ensuring the stability of the connection between the upper shell 1 and the lower shell 2.

[0039] By moving the operating rod 8 in the vertical direction, the lifting plate 14 can be changed in height, so that the installation rod 12 can be pulled to make the installation rod 12 leave the middle limit hole 17, so that the upper fixing plate 5 can move.

[0040] A limit ring 13 is fixedly mounted on one end of the mounting rod 12 away from the lifting plate 14 , two blocking blocks 18 are fixedly mounted on a single limit hole 17 , and a slot 19 for the limit ring 13 to enter is formed between the two corresponding blocking blocks 18 .

[0041] The limiting ring 13 in the initial position can be smoothly inserted into the limiting hole 17 through the insertion groove 19, and then the mounting rod 12 is rotated. The rotation of the mounting rod 12 causes the limiting ring 13 to change its position, and then the blocking block 18 will hinder the movement of the limiting ring 13, so that the limiting hole 17 of the limiting ring 13 is stable inside, thereby ensuring the stability of the connection between the upper shell 1 and the lower shell 2.

[0042] The operating rod 8 can rotate, and the operating rod 8 is fixedly connected to the mounting rod 12 at the center, and the centers of the two are on the same straight line. The mounting rod 12 at the center is connected to the mounting rods 12 on both sides through a synchronous belt 16.

[0043] When the operating rod 8 is rotated, the rotation of the operating rod 8 causes the central mounting rod 12 to rotate, and the rotation of the mounting rod 12 is transmitted to the mounting rods 12 on both sides through the synchronous belt 16, so that the three limiting rings 13 change their angles synchronously.

[0044] Preferably, a direction indicator may be attached to the operating rod 8 to display the actual angle of the limiting ring 13 to facilitate the establishment and cancellation of the connection activity.

[0045] The slider 9 is provided with a receiving cavity 20 for receiving the limiting ring 13 at a corresponding position. When the operating rod 8 is pulled to change the height of the lifting plate 14, the limiting ring 13 rises and is located inside the receiving cavity 20, so that the slider 9 can drive the upper fixed plate 5 to move smoothly.

[0046] A positioning block 11 is fixedly mounted on one end of the lower fixing plate 6 . When the slider 9 and the positioning block 11 contact each other, it means that the designated position has been reached. At this time, the mounting rod 12 corresponds to the limiting hole 17 .

[0047] The extended end of the lower fixing plate 6 is evenly and equidistantly fixed with placement holes 10 , which are through grooves and can accommodate the installation rods 12 .

[0048] When the upper shell 1 is moved to expose the space inside the motor, the upper shell 1 is located on the extended end of the lower fixing plate 6 . At this time, the mounting rod 12 is located inside the placement hole 10 , ensuring the stable placement of the upper shell 1 .

[0049] Two mounting brackets 3 are fixedly mounted on the bottom of the lower housing 2. Bolt holes 4 are provided on the two mounting brackets 3. The mounting brackets 3 and the bolt holes 4 enable the motor to be mounted at a designated position for driving activities.

[0050] The working process of the utility model is as follows: when disassembly is required, the operating rod 8 is moved in the vertical direction, and the lifting plate 14 is changed in height. At this time, the mounting rod 12 leaves the limiting hole 17, and the slider 9 can move inside the slide groove 7, thereby driving the upper fixed plate 5 to be displaced, so that the upper shell 1 moves synchronously, and the space inside the motor can be exposed, which is convenient for maintenance activities.

[0051] Since the length of the lower fixing plate 6 is greater than that of the upper fixing plate 5, the upper shell 1 will not fall when it is pulled out. The upper shell 1 will be on the extended end of the lower fixing plate 6, so that the upper shell 1 and the lower shell 2 are still connected together. At this time, the mounting rod 12 is inside the placement hole 10, ensuring the stable placement of the upper shell 1.

[0052] After the inspection is completed, when the operating rod 8 is pulled to change the height of the lifting plate 14, the limiting ring 13 rises and is located inside the accommodating chamber 20, so that the slider 9 can drive the upper fixing plate 5 to move smoothly, pushing the upper shell 1, so that the upper shell 1 and the lower shell 2 form a whole. When the slider 9 and the positioning block 11 contact each other, it means that the specified position has been reached. At this time, the mounting rod 12 corresponds to the limiting hole 17.

[0053] The force applied to the operating rod 8 is cancelled. The existence of the spring 15 makes the lifting plate 14 be in a lower position when no external force is applied. At this time, the mounting rod 12 is inside the limiting hole 17, and the limiting ring 13 can be smoothly inserted into the limiting hole 17 through the insertion groove 19.

[0054] Then, the operating rod 8 is rotated. The rotation of the operating rod 8 causes the mounting rod 12 in the center to rotate. The rotation of the mounting rod 12 is transmitted to the mounting rods 12 on both sides through the synchronous belt 16, so that the three limit rings 13 change their angles synchronously. Then, the blocking block 18 will hinder the movement of the limit ring 13, so that the stable limit hole 17 of the limit ring 13 is located inside, thereby ensuring the stability of the connection between the upper shell 1 and the lower shell 2.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
