[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0029] like Figures 1-9 As shown, an installation structure of an electrical equipment includes a mounting rail 1, a mounting base 2, a drive assembly 5, a rotating seat 6 and a trigger assembly 8. Among them, the mounting rail 1 is a prior art, which includes a main body and clamping parts on both sides. The main body is mainly used to be fixedly connected to the inner wall of the electrical cabinet, and the clamping parts on both sides are mainly used to clamp and cooperate with the electrical equipment. The mounting base 2 mainly plays the role of installation and support, and can provide a carrier for installation and support of corresponding components. The rotating seat 6 also mainly plays the role of installation and support. A mounting plate 61 is fixedly connected to the rotating seat 6, and the PLC can be fixedly connected to the mounting plate 61. The drive assembly 5 mainly provides power for the corresponding components. The trigger assembly 8 is mainly used to selectively control the rotation and limit of the rotating seat 6.

[0030] Specifically, if Figure 2As shown, the mounting base 2 includes: a bottom plate 21, a top plate 22, a first side plate 23, and a second side plate 24. The bottom plate 21 and the top plate 22 are arranged parallel to each other, the first side plate 23 and the second side plate 24 are arranged parallel to each other, and the first side plate 23 and the second side plate 24 are both fixedly connected to the bottom plate 21 and the top plate 22. In this way, a mounting hole 25 with openings at both ends can be defined between the bottom plate 21, the top plate 22, the first side plate 23, and the second side plate 24. It should be noted that the mounting base 2 is mainly used to cooperate with the mounting rail 1. When in use, the bottom plate 21 is arranged to fit the clamping parts on both sides, and the top plate 22 is arranged on the side away from the mounting rail 1. In addition, the connection direction between the openings on both sides of the mounting hole 25 is the width direction of the mounting rail 1, which facilitates the subsequent cooperation between the mounting base 2 and the mounting rail 1.

[0031] Further, if Figure 2 and Figure 5 As shown, a first claw 3 and a second claw 4 are slidably connected within the mounting hole 25, and the first claw 3 and the second claw 4 respectively abut and cooperate with the engaging portions on both sides of the mounting rail 1. It should be noted that the first claw 3 and the second claw 4 are both slidably connected to the base plate 21, and the sliding directions of the first claw 3 and the second claw 4 are both along the width direction of the mounting rail 1. Specifically, the first claw 3 and the second claw 4 can both be L-shaped structures, which facilitates the abutment and cooperation of the first claw 3 and the second claw 4 with the corresponding engaging portions.

[0032] When in use, in the initial state, the distance between the ends of the first clamping claw 3 and the second clamping claw 4 that are away from each other is greater than the width of the mounting guide rail 1, so that a larger installation space can be reserved for the installation of the mounting base 2, making it easier to install the mounting base 2. When the bottom plate 21 in the mounting base 2 contacts the surfaces of the clamping parts on both sides, the driving component 5 is used to simultaneously retract the first clamping claw 3 and the second clamping claw 4 inward. During the retraction process, the first clamping claw 3 and the second clamping claw 4 will respectively abut against the corresponding clamping parts, thereby fixing the mounting base 2 and the mounting guide rail 1. When the mounting base 2 needs to be removed, the driving component 5 is used to simultaneously extend the first clamping claw 3 and the second clamping claw 4 outward, so that the first clamping claw 3 and the second clamping claw 4 will respectively disengage from the corresponding clamping parts, thereby separating the mounting base 2 from the mounting guide rail 1. It should be noted that the driving component 5 is arranged on the mounting base 2 and is used to simultaneously drive the first clamping claw 3 and the second clamping claw 4 away from or towards each other.

[0033] Specifically, if Figure 3 、 Figure 7-Figure 9As shown, the drive assembly 5 includes a first rack plate 51, a second rack plate 52, a gear 53, a worm gear 54, a worm 55, a transmission shaft 56, and two knobs 57. The first rack plate 51 is fixedly connected to the side of the first jaw 3 facing the second jaw 4, and the second rack plate 52 is fixedly connected to the side of the second jaw 4 facing the first jaw 3. The transmission shaft 56 is rotatably connected to the base plate 21, and the axis of the transmission shaft 56 is perpendicular to the base plate 21. The gear 53 and the worm gear 54 are both fixedly connected to the transmission shaft 56. The gear 53 meshes with the first rack plate 51 and the second rack plate 52 simultaneously. It should be noted that the first rack plate 51 and the second rack plate 52 are parallel to each other and are disposed on either side of the gear 53. Thus, when the gear 53 rotates, it simultaneously drives the first rack plate 51 and the second rack plate 52 on both sides to move in opposite directions. This, in turn, drives the first and second claws 3 and 4 on both sides to move in opposite directions through the transmission of the first and second rack plates 51 and 52, thereby achieving the fixation and disengagement between the mounting base 2 and the mounting rail 1. The ends of the worm 55 are rotatably connected to the first and second side plates 23 and 24, respectively. The ends of the worm 55 extend out of the first and second side plates 23 and 24 and are fixedly connected to the knob 57. The worm 55 is adapted to the worm gear 54.

[0034] During use, when it is necessary to fix the mounting base 2 to the mounting guide rail 1, the bottom plate 21 is first brought into contact with the surfaces of the clamping portions on both sides of the mounting guide rail 1, and then the knob 57 on one side is turned. The rotation of the knob 57 drives the worm 55 to rotate, and the rotation of the worm 55, through cooperation with the worm gear 54, drives the transmission shaft 56 to rotate. The rotation of the transmission shaft 56 in turn drives the gear 53 to rotate. The rotation of the gear 53, through cooperation and transmission with the first rack plate 51 and the second rack plate 52, can drive the first clamping claw 3 and the second clamping claw 4 to move closer to each other to clamp the mounting guide rail 1, thereby achieving the fixation between the mounting base 2 and the mounting guide rail 1. When it is necessary to separate the mounting base 2 from the mounting guide rail 1, the knob 57 is turned in the opposite direction.

[0035] It should be noted that knobs 57 are fixedly connected to both ends of the worm 55, allowing installation from both sides of the mounting base 2, providing greater flexibility. For example, if the mounting base 2 is installed near the right side of the electrical cabinet, it would be inconvenient to operate the right knob 57. In this case, the left knob 57 can be turned to rotate the worm 55. Furthermore, the worm 55 and worm wheel 54 have a self-locking effect, preventing the shaking of the first and second jaws 3 and 4 from driving the worm 55 in the opposite direction, thereby further stabilizing the connection between the mounting base 2 and the mounting rail 1.

[0036] In addition, if Figure 2 、 Figure 5and Figure 6 As shown, the rotating base 6 is rotatably connected to the mounting base 2. Specifically, the rotating base 6 can be a cylindrical structure and is rotatably connected to the top plate 22, wherein a portion of the rotating base 6 is located inside the top plate 22 and another portion extends outside the top plate 22. A mounting plate 61 fixedly connected to the rotating base 6 is fixedly connected to the PLC. The mounting plate 61 is arranged on the side of the rotating base 6 away from the mounting guide rail 1, which facilitates the fixing of the mounting plate 61 to the PLC.

[0037] A cavity 62 is defined within the rotating base 6, primarily providing mounting space. Part of this cavity 62 is located within the top plate 22, while another portion is located outside the top plate 22. A first sliding hole 63 is defined on the circumferential wall of the rotating base 6, communicating with the cavity 62. A limit block 7 is slidably connected within the cavity 62, and multiple limit holes 221 are defined on the top plate 22. It should be noted that the limit block 7 slides radially along the rotating base 6. The limit block 7 can slide through the first sliding hole 63 and selectively engage with any of the limit holes 221.

[0038] During use, when the angle of the PLC device needs to be adjusted, that is, when the position of the mounting plate 61 needs to be adjusted, the rotating base 6 can be rotated. The rotation of the rotating base 6 will drive the mounting plate 61 to rotate, thereby driving the PLC device to rotate. When the position of the PLC device is adjusted to a preset angle, the first sliding hole 63 is connected to one of the limiting holes 221, pushing the limiting block 7 to slide outward. During the sliding process of the limiting block 7, one end of the limiting block 7 will pass through the first sliding hole 63 and extend into the corresponding limiting hole 221, while the other end of the limiting block 7 remains in the cavity 62, thereby limiting the free rotation of the rotating base 6 and maintaining the stability of the PLC device. When the angle of the PLC device needs to be adjusted again, the limiting block 7 is moved in the opposite direction. At this time, the limiting block 7 will gradually disengage from the limiting hole 221, and the limit on the rotating base 6 is released. The rotating seat 6 is continuously rotated until the preset angle is reached. At this time, the first sliding hole 63 is connected with the corresponding limiting hole 221 , and the limiting block 7 is pushed to engage with the corresponding limiting hole 221 .

[0039] In addition, if Figure 5 and Figure 6As shown, the trigger assembly 8 is arranged on the rotating seat 6, and is used to drive the limit block 7 to move so that the limit block 7 passes through the first sliding hole 63 and selectively cooperates with any limit hole 221. Specifically, a second sliding hole 64 connected to the cavity 62 is provided on the rotating seat 6. The trigger assembly 8 includes: a trigger rod 81, a fixed shaft 82 and a drive rod 83. The drive rod 83 is fixedly connected to the limit block 7, and the fixed shaft 82 is fixedly connected inside the cavity 62. The fixed shaft 82 is rotatably connected to the middle position of the trigger rod 81, that is, the trigger rod 81 can rotate around the axis of the fixed shaft 82. One end of the trigger rod 81 passes through the outside of the second sliding hole 64, which facilitates the operation of the trigger rod 81. The other end of the trigger rod 81 is provided with a drive hole 811 along its own length direction, and the drive rod 83 is slidably connected to the drive hole 811. It should be noted that the driving hole 811 is a long strip hole, and the width of the driving hole 811 can be the same as the diameter of the driving rod 83, and the length of the driving hole 811 is greater than the diameter of the driving rod 83. In this way, when the trigger rod 81 rotates, it can drive the driving rod 83 to move through the constraint of the driving hole 811, thereby driving the limit block 7 to move, and then realizing selective limiting cooperation between the limit block 7 and the corresponding limit hole 221.

[0040] As an optional embodiment, a hexagonal hole for use with an hexagonal wrench is provided on the side of the knob 57 away from the mounting base 2. Due to limited human strength, it is difficult to adjust the pressure between the first and second jaws 3, 4 and the mounting rail 1 to a higher level by rotating the knob 57. In this case, the hexagonal wrench can be used to tighten the worm 55, thereby increasing the pressure between the first and second jaws 3, 4 and the mounting rail 1. This can make the connection between the mounting base 2 and the mounting rail 1 more secure and stable, thereby making the installation of the PLC device more secure and stable.

[0041] As an optional embodiment, the plurality of limiting holes 221 are distributed in a circular array about the axis of the rotating seat 6. This can make the distribution of the limiting holes 221 more uniform, so that the operator can better understand the position of the limiting holes 221 and thus facilitate adjustment of the position of the limiting block 7.

[0042] In addition, if Figure 2 and Figure 4 As shown, in a direction perpendicular to the plane of the mounting rail 1, the projection of one end of the trigger lever 81 on that plane is contained within the projection of the mounting plate 61 on that plane. In other words, one end of the trigger lever 81 is hidden beneath the mounting plate 61, which reduces interference between the trigger lever 81 and the outer ring, thereby reducing accidental operation of the trigger lever 81 and improving the safety of the device.

[0043] As an optional embodiment, Figure 9 As shown, a guide hole 71 is defined within the stop block 7, and a guide rod 9 is fixedly connected to the inner wall of the cavity 62, with the guide rod 9 slidingly engaging with the guide hole 71. Both the guide hole 71 and the guide rod 9 serve as guides. By positioning the guide hole 71 within the stop block 7 and fixing the guide rod 9 to the inner wall of the cavity 62, when the trigger rod 81 drives the stop block 7 through the drive hole 811 and the drive rod 83, the cooperation between the guide hole 71 and the guide rod 9 stabilizes the movement of the stop block 7 and prevents it from deflecting.

[0044] In addition, if Figure 6 As shown, the installation structure of the electrical equipment also includes a spring 10, which is sleeved on the guide rod 9, and the two ends of the spring 10 respectively contact and cooperate with the limit block 7 and the inner wall of the cavity 62. Among them, the spring 10 mainly plays a reset role. When the limit block 7 is not engaged with the limit hole 221, the spring 10 is in a compressed state. When the first sliding hole 63 is connected to the limit hole 221, the trigger rod 81 is released, and the limit block 7 will pop out under the action of the restoring force of the spring 10 and engage with the corresponding limit hole 221, making it more convenient to use. In addition, the spring 10 can also maintain the relative stability of the position of the limit block 7 and the limit hole 221.

[0045] As an optional embodiment, Figure 3 As shown, two limit plates 100 are fixedly connected to the side of the bottom plate 21 away from the top plate 22, and the two limit plates 100 are respectively arranged in contact with the two inner walls opposite to the mounting rail 1. Among them, the limit plates 100 mainly play a limiting role. It should be noted that the two inner walls opposite to the mounting rail 1, i.e., the position where the main body and the clamping part are connected, are respectively arranged in contact with the two inner walls opposite to the mounting rail 1. In this way, the mounting base 2 can be limited from the inside, and the external limitation of the first clamping claw 3 and the second clamping claw 4 can be cooperated, so that the connection between the mounting base 2 and the mounting rail 1 can be made more stable.

[0046] The above describes the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
