[0042] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0043] See also Figure 1 to Figure 4 , this embodiment provides a low-voltage motor, including a housing 1 and a mounting structure.

[0044] The housing 1 has a circumferential side and a rear end cover. A plurality of first threaded holes are arranged on the same side of the circumferential side of the housing 1, and a plurality of second threaded holes 3 are arranged on the opposite sides of the circumferential side of the housing 1. The first threaded holes and the second threaded holes 3 are used to connect the lifting ring 2. When installed horizontally ( Figure 1 The figure shows a horizontal installation state), a lifting ring 2 is installed on the first threaded hole to facilitate lifting; when installed vertically, a lifting ring 2 is installed on the second threaded hole 3 to facilitate lifting.

[0045] Compared with the binding hoisting method, the present embodiment facilitates hoisting and increases hoisting stability by providing the hoisting ring 2. In addition, according to the needs of horizontal installation and vertical installation, a first threaded hole and a second threaded hole 3 for connecting the hoisting ring 2 are provided at corresponding positions on the circumferential side of the housing 1, thereby enhancing the flexibility of the low-voltage motor during installation.

[0046] The mounting structure includes a first connecting member 4 , a second connecting member 5 and a mounting seat 6 .

[0047] A plurality of first connecting members 4 are arranged on the circumferential side of the housing 1. In a specific implementation scenario, there are four first connecting members 4, and the four first connecting members 4 are distributed in a rectangular array.

[0048] A plurality of second connecting members 5 are disposed at the rear end of the housing 1. In a specific implementation scenario, there are four second connecting members 5, and the four second connecting members 5 are distributed in a rectangular array.

[0049] The first connecting member 4 or the second connecting member 5 is detachably connected to the mounting base 6, and the mounting base 6 is connected to a designated device.

[0050] In horizontal installation, the first connector 4 is detachably connected to the designated device through the mounting seat 6, thereby realizing horizontal installation of the low-voltage motor; in vertical installation, the second connector 5 is detachably connected to the designated device through the mounting seat 6, thereby realizing vertical installation of the low-voltage motor. It can be seen that the present application can be changed to vertical installation or horizontal installation according to actual needs, which is more flexible.

[0051] It should be noted that, regarding the connection method between the second connecting member 5 and the shell 1: each second connecting member 5 can be directly connected to the rear end of the shell 1, or one end of the second connecting member 5 can be connected to the circumferential side of the shell 1 and the other end of the second connecting member 5 can be extended to the rear end of the shell 1, as long as the second connecting member 5 is completely or partially located at the rear end of the shell 1 in terms of spatial dimensions, it is sufficient to facilitate connection with the mounting seat 6.

[0052] The first connecting member 4 and / or the second connecting member 5 are detachably connected to the mounting base 6 in the following manner: a plurality of plug rods are provided on the mounting base 6, the bottom ends of the first connecting member 4 and / or the second connecting member 5 are opened to be socketed with the plug rods, and the side walls of the first connecting member 4 and / or the second connecting member 5 are provided with pin holes 41 for one end of the fixing bolt to pass through, and one end of the fixing bolt passes through the pin hole 41 and is threadedly connected with the plug rod to achieve positioning and fixation of the first connecting member 4 and / or the second connecting member 5 on the mounting base 6.

[0053] In this embodiment, preferably, the first connecting member 4 and the second connecting member 5 are both detachably connected to the mounting base 6 in the above-mentioned manner, thereby facilitating the conversion of the low-voltage motor between horizontal installation and vertical installation.

[0054] The mounting seat 6 is connected to the designated device in the following manner: the four corners of the mounting seat 6 are provided with adjustment holes 61 through which the rod of the locking bolt 7 can pass; the head of the locking bolt 7 is located outside the adjustment hole 61 and directly or indirectly contacts the mounting seat 6; the rod of the locking bolt 7 passes through the adjustment hole 61 and is exposed outside the mounting seat 6 to facilitate installation on the designated device. The advantage of the mounting seat 6 being connected to the designated device in the above manner is that the relative position of the mounting seat 6 and the designated device can be fine-tuned, thereby facilitating adjustment of the tension of the matching connecting belt. The adjustment hole 61 can be, for example, a waist-shaped hole.

[0055] In this embodiment, preferably, the width and length of the adjustment hole 61 are greater than the diameter of the rod of the locking bolt 7, so that the relative position between the mounting base 6 and the designated device in multiple directions can be adjusted. Specifically, in horizontal installation, by adjusting the width direction of the adjustment hole 61 ( Figure 3 The mounting base 6 is moved in the left and right directions as shown to adjust the relative position of the mounting base 6 and the specified device; when installed vertically, the mounting base 6 is moved along the length direction of the adjustment hole 61 ( Figure 3 The mounting base 6 is moved in the front-to-back direction (as shown) to adjust the relative position of the mounting base 6 and the designated device.

[0056] The mounting structure may further include a positioning plate 8 disposed between the mounting seat 6 and the head of the locking bolt 7, wherein the width of the positioning plate 8 is greater than the width of the adjustment hole 61, the rod of the locking bolt 7 can pass through the positioning plate 8, but the head of the locking bolt 7 cannot pass through the positioning plate 8, so that there is no need to consider the size of the head of the locking bolt 7.

[0057] In this embodiment, preferably, there are two positioning plates 8 , and each positioning plate 8 is connected to two locking bolts 7 , respectively.

[0058] Furthermore, a plurality of first anti-skid protrusions 62 are provided on one side of the mounting seat 6, and a plurality of second anti-skid protrusions 81 used in conjunction with the first anti-skid protrusions 62 are provided on one side of the positioning plate 8. When the mounting seat 6 and the positioning plate 8 are in contact, the first anti-skid protrusions 62 and the second anti-skid protrusions 81 can be staggered to increase friction, avoid relative sliding between the mounting seat 6 and the positioning plate 8, and facilitate the positioning of the mounting seat 6.

[0059] When installing a low-voltage motor horizontally, first connect the first connecting member 4 to the mounting seat 6, and then connect the locking bolt 7 to the designated device to achieve installation. When it is necessary to adjust the relative position of the mounting seat 6 and the designated device to adjust the tension of the matching connecting belt, loosen the locking bolt 7, lift the positioning plate 8 upward, so that the first anti-slip protrusion 62 is separated from the second anti-slip protrusion 81, and then push the mounting seat 6 to move within the range of the adjustment hole 61 to adjust the position. After adjustment, put down the positioning plate 8, so that the first anti-slip protrusion 62 is staggered with the second anti-slip protrusion 81, and re-tighten the locking bolt 7 to complete the adjustment of the tension of the matching connecting belt. When installing a low-voltage motor vertically, refer to the above process.

[0060] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will.
