DETAILED DESCRIPTION
[0032] In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.
[0033] According to the utility model embodiment, a limiting tool is provided, please refer to Figures 1 to 12 , including: first limiting plate 1 and second limiting plate 2, first limiting plate 1 is provided with first clamping groove 11, first limiting plate 1 and second limiting plate 2 between there is second clamping groove 3, the extension direction of first clamping groove 11 and the extension direction of second clamping groove 3 are set same direction;The thickness of at least one limiting plate of first limiting plate 1 and second limiting plate 2 is equal to the standard gap 7 between rotating part 51 and partition plate 52 in air conditioner shell 5;Insert limiting tool, so that first clamping groove 11 is clamped on air conditioner shell 5 air duct plate 53, second clamping groove 3 is clamped on partition plate 52. Please refer to Figure 1 、 Figure 2 and Figure 3To explain, the inside of the air conditioner shell 5 is provided with an air duct plate 53, which is arranged along the length direction of the air conditioner shell 5, and is used to guide the airflow of the outlet of the cross-flow fan blade installed on the rotating part 51, and the rotating part 51 is separated from the motor 54 driving its rotation by a partition plate 52 (the partition plate 52 is also provided with a clamping groove for clamping the motor, and also has the function of fixing the motor). The partition plate 52 has a circular hole for the motor shaft to pass through, and the air duct plate 53 is arranged vertically with the partition plate 52. In order to accurately control the gap between the rotating part 51 and the partition plate 52, that is, to realize the standardization of the gap, the actual installation gap is positioned by the thickness of the first limiting plate 1 or the second limiting plate 2 being equal to the standard gap 7 between the rotating part 51 and the partition plate 52. (If the thickness of the first limiting plate 1 is equal to the standard gap 7, the first limiting plate 1 is next to the rotating part 51, and then the second limiting plate 2 is on the other side of the partition plate 52; if the thickness of the second limiting plate 2 is equal to the standard gap 7, the second limiting plate 2 is next to the rotating part 51, and then the first limiting plate 1 is on the other side of the partition plate 52; if the thickness of both is equal to the standard gap 7, they have greater flexibility when clamped.) In this embodiment, the thickness of the first limiting plate 1 and the second limiting plate 2 is equal to the standard gap 7, and the use method is illustrated by taking the first limiting plate 1 abutting the rotating part 51 as an example. First, the first clamping groove 11 of the limiting tool is clamped on the air duct plate 53 of the air conditioner shell 5, so that the limiting tool is fixed with the shell and prevents the limiting tool from being tilted during use; then, since the thickness of the first limiting plate 1 is equal to the standard gap 7, the rotating part 51 is close to the first limiting plate 1, so that one side of the rotating part 51 abuts the first limiting plate 1; then, the motor 54 is installed, and the extension length of the motor shaft is adjusted until the opposite side of the partition plate 52 abuts the first limiting plate 1. In this way, it is ensured that the gap between the partition plate 52 and the rotating part 51 meets the specifications. The design of such a limiting tool solves the problem that it is difficult to accurately control the gap between the partition plate and the cross-flow fan rotating part in traditional installation, thereby ensuring the normal operation of the air conditioner, reducing friction and noise, and improving overall performance. The limiting tool of the embodiment solves the technical problem that the traditional installation and limiting structure in the related art is difficult to accurately control the gap between the partition plate and the cross-flow fan rotating part, and the error is easy to affect the operation effect of the air conditioner.
[0034] Referring to Figure 4 , Figure 5 and Figure 6The limiting tool of the embodiment further comprises a third limiting plate 4 located between the first limiting plate 1 and the second limiting plate 2, and the first limiting plate 1, the second limiting plate 2 and the third limiting plate 4 are detachably connected. The third limiting plate 4 not only serves to connect the first limiting plate 1 and the second limiting plate 2, but also adjusts the width of the second clamping groove 3, thereby clamping the partition plate 52 of different thicknesses. Each limiting plate is detachable, so that the limiting tool can be flexibly adjusted according to different air conditioner models and installation requirements.
[0035] Referring to Figure 2 and Figure 6 The limiting tool of the embodiment comprises a third limiting plate 4 comprising a connecting plate 41 and a handle 42, the connecting plate 41 and the handle 42 are connected, the handle 42 extends outward relative to the first limiting plate 1 and the second limiting plate 2 to facilitate the taking of the limiting tool; the connecting plate 41, the first limiting plate 1 and the second limiting plate 2 are detachably connected, and the first limiting plate 1, the connecting plate 41 and the second limiting plate 2 are connected in sequence to enclose the second clamping groove 3. The handle 42 extends outward relative to the first limiting plate 1 and the second limiting plate 2, avoiding interference with other parts of the tool when taking, improving the convenience and efficiency of operation.
[0036] Referring to Figure 2 , Figure 6 and Figure 7 The limiting tool of the embodiment, the handle 42 extends in a direction opposite to the second clamping groove 3. The handle 42 extending in the opposite direction provides a wider operating space for the workers. This makes them easier to access and operate the workpiece, especially in environments where the air conditioner housing 5 space is limited.
[0037] Referring to Figure 2 The limiting tool of the embodiment, the second clamping groove 3, the connecting plate 41 and the handle 42 are arranged in a straight line to facilitate alignment of the partition plate 52 for quick insertion. The straight line arrangement makes the second clamping groove 3, the connecting plate 41 and the handle 42 form a clear straight line visually, which helps workers more easily align the partition plate 52 and insert the partition plate 52 into the second clamping groove 3. This design reduces the difficulty or error caused by inaccurate alignment, improving the accuracy and efficiency of operation.
[0038] Referring to Figure 8 , Figure 9 and Figure 10The limiting tool of the embodiment, the first clamping groove 11 penetrates the front end part of the first limiting plate 1, the first limiting plate 1 is attached to one side of the connecting plate 41, and the second limiting plate 2 is attached to a part of the opposite side of the connecting plate 41, so that the first limiting plate 1 is located on the first plane, the connecting plate 41 is located on the second plane, and the second limiting plate 2 is located on the third plane, the first plane, the second plane, and the third plane are parallel to each other; a fourth plane is provided with the first clamping groove 11 as a boundary line, the fourth plane is perpendicular to the first plane, the second plane, and the third plane, the connecting plate 41 is located on one side of the fourth plane, and the handle 42 is located on the other side of the fourth plane. The first clamping groove 11 as a boundary line not only penetrates the front end part of the first limiting plate 1, but also serves as a guide for inserting workpieces or other components. Due to the parallelism of the first plane, the second plane, and the third plane, and the perpendicularity of the fourth plane, the alignment and insertion process is more simple and direct, reducing errors and difficulties. The handle 42 is located on the other side of the fourth plane, opposite the connecting plate 41, which makes it easier for workers to grasp the handle 42 and move the entire limiting tool along the air duct plate 53.
[0039] Referring to Figure 8 The limiting tool of the embodiment further comprises at least two first fasteners 61, each first fastener 61 sequentially penetrating the first limiting plate 1, the connecting plate 41, and the second limiting plate 2, thereby connecting the first limiting plate 1, the third limiting plate 4, and the second limiting plate 2, and each first fastener 61 is detachably arranged. Since the first fasteners 61 are detachable, the limiting tool can more easily adapt to different workpieces and installation scenarios, allowing workers to flexibly adjust the size, shape, and configuration of the limiting tool to meet different processing needs.
[0040] Referring to Figure 9 , Figure 10 and Figure 11 The limiting tool of the embodiment further comprises a second fastener 62, which is detachably arranged, the second fastener 62 is arranged in a direction opposite to the first fastener 61, and the second fastener 62 is arranged in a staggered manner with the first fastener 61. The use of the second fastener 62 in combination with the first fastener 61 fixes the various components of the limiting tool from two different directions, forming a more stable overall structure. The staggered arrangement of the second fastener 62 and the first fastener 61 forms staggered fixing points on the connecting plate. This staggered distribution of fixing points is more uniform and helps to distribute stress on the connecting plate, improving the connection strength.
[0041] Referring to Figure 1 , Figure 8 and Figure 9The end of the first limiting plate 1 and the end of the second limiting plate 2 are provided with arc-shaped structures matched with the air conditioner shell 5. The matching design of the arc-shaped structures and the air conditioner shell 5 enables the limiting tool to be more accurately positioned on the air conditioner shell 5.
[0042] Referring to Figure 12 The application of the limiting tool in the installation of the air conditioner is described above. In the art, the limiting tool can also be referred to as a plug gauge. The operation method of using the plug gauge is as follows: an operator holds the handle 42 and places it on the bottom shell air duct plate 53 near the motor side; according to the operation requirements, a 6mm thick plug gauge (i.e., the limiting plate) is inserted between the cross-flow fan blade rotating part 51 and the partition plate 52 for positioning, the fan blade is pushed to one side of the plug gauge, the cross-flow fan blade rotating part 51, the plug gauge and the partition plate 52 are tightly attached, and the plug gauge avoids the boss on the side of the fan blade; then, the fan blade rotating part 51 is rotated to make the motor shaft and the fan blade fixing screw vertically aligned, and the screw is fastened; the plug gauge is pulled out, the fixing of the gap between the partition plate 52 and the rotating part 51 is completed, and the fan blade is checked for fixation by being pushed. For different shells, the second limiting plate 2 can also be used for adjustment according to the motor side gap and the partition plate 52. The first clamping groove 11 of the first limiting plate 1 is used to fix the tool clamping on the air duct plate 53 to achieve the tool limiting function and prevent the tool from being warped during use; the second limiting plate 2 fixes the motor side limiting to prevent the use of the tool in the wrong position from causing abnormal assembly of the whole machine. During the operation, the tool is assembled with the air conditioner shell 5 in position, the two limiting structures are used to prevent abnormal placement of the tool, so as to achieve stable gap positioning. When the side of the cross-flow fan blade rotating part 51 is worn out after long-term use, the first limiting plate 1 can be removed alone, and the use can be satisfied after the first limiting plate 1 of qualified thickness is replaced, without the need to replace the whole tool. Compared with the traditional tool, the tool is completely fitted to the bottom shell model structure, and in the specific operation process, the limiting device is used to increase positioning for specific position limitation, so as to prevent abnormal assembly of the fan blade caused by the state of the personnel, the operation method, abnormal positioning of the tool, cause the left and right gaps to be inconsistent, and cause abnormal problems such as noise during operation of the whole machine.
