[0055] Typical embodiments that embody the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various variations in different embodiments without departing from the scope of the present disclosure, and the description and drawings therein are essentially for illustrative purposes rather than for limiting the present disclosure.

[0056] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of this disclosure and in which are shown by way of example different exemplary structures, systems and steps that may implement aspects of the present disclosure. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps may be used, and structural and functional modifications may be made without departing from the scope of the present disclosure. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein for convenience only, for example, according to the directions of the examples depicted in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of a structure to fall within the scope of the present disclosure.

[0057] See Figure 1 , which representatively illustrates a perspective schematic diagram of the coupling shield 100 proposed in the present disclosure. In this exemplary embodiment, the coupling 400 proposed in the present disclosure is described as being applied to covering the moving parts between the motor 200 and the bearing housing 300. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of the present disclosure to the covering and protection of other structures. Such changes will still fall within the scope of the principles of the coupling shield 100 proposed in the present disclosure.

[0058] like Figure 1As shown, in one embodiment of the present disclosure, the coupling shield 100 proposed in the present disclosure is used to cover the moving parts between the motor 200 and the bearing box 300, wherein the coupling shield 100 includes a shielding component 110, a retaining ring 120 and a baffle 130. Figures 2 to 5 , Figure 2 Representatively shown in Figure 1 Schematic diagram of the three-dimensional decomposition of Figure 3 A perspective schematic diagram of the baffle 130 is representatively shown in FIG; Figure 4 A schematic plan view of the baffle 130 is representatively shown in FIG; Figure 5 1 is a representative perspective view of the protective component 110. The following will describe in detail the structure, connection mode and functional relationship of the main components of the coupling protective cover 100 proposed in this application in conjunction with the above drawings.

[0059] like Figures 1 to 5 As shown, in one embodiment of the present disclosure, the protective component 110 is a cylindrical structure, and along a first direction parallel to the axis 210 of the moving component (for example, the direction D1 in the accompanying drawings), the two end openings of the protective component 110 are respectively a first opening 1101 away from the motor 200 and a second opening 1102 close to the motor 200. The retaining ring 120 is provided at the first opening 1101 of the protective component 110, and the side of the retaining ring 120 facing away from the motor 200 is used to connect to the bearing box 300. The baffle 130 is provided at the second opening 1102 of the protective component 110, and the baffle 130 is provided with an avoidance portion penetrating along the first direction, and the avoidance portion is used for the shaft 210 of the power supply motor 200 to pass through. Accordingly, the protective component 110, the retaining ring 120 and the baffle 130 together form a accommodating chamber for enclosing the moving component (see also Figures 10 to 12 As shown). Through the above-mentioned structural design, the present disclosure utilizes the accommodating chamber formed by the protective component 110, the retaining ring 120 and the baffle 130 to achieve a complete envelope of the moving parts, thereby realizing the design of the coupling protective cover 100 with complete geometric features. In contrast, the existing solutions may not meet the protection requirements of safety regulations due to factors such as the lack of suitable matching dimensions between the motor body and the existing shield, the size of certain brands of motors, and the presence of special-shaped features on the front cover of the series. However, the present disclosure can weaken or even ignore the above-mentioned problems through the above-mentioned structural design. Furthermore, on the basis of realizing a more comprehensive safety protection function, the present disclosure also has the advantages of low cost, simple assembly, and strong compatibility.

[0060] like Figures 2 to 4As shown, in one embodiment of the present disclosure, the avoidance portion can be a avoidance groove 131, which extends along a second direction perpendicular to the first direction (e.g., direction D2 in the accompanying drawings), and the avoidance groove 131 opens at the edge of the baffle 130. Through the above structural design, during the assembly process, the present disclosure can utilize the opening of the avoidance groove 131 of the baffle 130 to allow the moving part (e.g., the shaft 210) to move into the avoidance groove 131, and during the disassembly process, the present disclosure can utilize the opening of the avoidance groove 131 to allow the moving part to move out of the avoidance groove 131. On this basis, the present disclosure can achieve assembly and disassembly of the baffle 130 without disassembling the moving parts, further reducing the difficulty of assembly and disassembly and improving efficiency.

[0061] like Figure 4 As shown, based on the structural design of the avoidance portion being an avoidance groove 131, in one embodiment of the present disclosure, the avoidance groove 131 may include a first groove portion 1311 and a second groove portion 1312. Specifically, the first groove portion 1311 is disposed in the middle portion of the baffle 130, and the width of the first groove portion 1311 is greater than the outer diameter of the shaft 210. Therefore, after the baffle 130 is assembled, the first groove portion 1311 can be used to accommodate the shaft 210, while preventing contact between the groove wall of the avoidance groove 131 and the shaft 210, ensuring that the rotation of the shaft 210 is not affected. The second groove portion 1312 extends along the second direction, with one end connected to the first groove portion 1311 and the other end open to the edge of the baffle 130. The width of the second groove portion 1312 is greater than or equal to the outer diameter of the shaft 210, thereby facilitating the movement of the shaft 210 into or out of the first groove portion 1311 via the second groove portion 1312.

[0062] like Figure 4 As shown, based on the structural design of the avoidance groove 131 including the first groove portion 1311 and the second groove portion 1312, in one embodiment of the present disclosure, the first groove portion 1311 can be semicircular, and the corresponding circular diameter of the semicircle is larger than the outer diameter of the shaft 210. In addition, the second groove portion 1312 has two groove walls opposite to each other along a third direction (for example, the D3 direction in the accompanying drawings), and the third direction is perpendicular to the first direction and perpendicular to the second direction. The two groove walls are respectively parallel to the second direction, and the spacing between the two groove walls in the third direction is equal to the corresponding circular diameter of the semicircle. Accordingly, the avoidance groove 131 is roughly "U"-shaped. In some other embodiments of the present disclosure, the spacing between the two groove walls of the second groove portion 1312 can also be greater than or less than the corresponding circular diameter mentioned above, as long as the spacing between the two groove walls is greater than or equal to the outer diameter of the shaft 210. Furthermore, the groove wall of the second groove portion 1312 is also arranged to be inclined relative to the second direction (for example, with an angle greater than 0 and less than 90°) to ensure that the minimum distance between the two second groove portions 1312 is greater than or equal to the outer diameter of the shaft 210.

[0063] like Figure 1 and Figure 2As shown, based on the structural design that the avoidance portion is the avoidance groove 131, in one embodiment of the present disclosure, there can be two baffles 130. Moreover, the opening directions of the avoidance grooves 131 of the two baffles 130 are different, so that a portion of each of the two avoidance grooves 131 together forms a channel for the shaft 210 to pass through. For example, when the avoidance groove 131 adopts the above-mentioned structural design including the semicircular first groove portion 1311 and the second groove portion 1312, the channel jointly formed by the avoidance grooves 131 of the two baffles 130 is circular. Through the above-mentioned structural design, the channel shape jointly formed by the two avoidance grooves 131 of the present disclosure matches the geometric shape of the shaft 210 in the circumferential direction, that is, the two baffles 130 are used to achieve a complete envelope of the shaft 210 in the circumferential direction, further improving the protection effect. Moreover, both baffles 130 can use their own avoidance grooves 131 to achieve more separate assembly and disassembly, without the need to disassemble moving parts.

[0064] like Figure 2 As shown, based on the structural design of two baffles 130, in one embodiment of the present disclosure, the opening directions of the avoidance grooves 131 of the two baffles 130 can be opposite. Through this structural design, the present disclosure can make the shape of the channel formed by the two avoidance grooves 131 closer to a circle. For example, when the avoidance groove 131 adopts the structural design comprising the semicircular first groove portion 1311 and the second groove portion 1312, the structural design of the avoidance grooves 131 of the two baffles 130 with opposite opening directions can achieve the shape of the channel as a complete circle.

[0065] See Figure 6 and Figure 7 As shown, Figure 6 : A perspective view of another exemplary embodiment of a coupling shield 100 that can embody the principles of the present disclosure is representatively shown; Figure 7 Representatively shown in Figure 6 Schematic diagram of three-dimensional decomposition.

[0066] Different from Figure 2 In the embodiment shown, a structure design with two baffles 130 is adopted, such as Figure 6 and Figure 7 As shown, in one embodiment of the present disclosure, still taking the avoidance portion as the avoidance groove 131 as an example, there can be one baffle 130 .

[0067] See Figure 8 As shown, Figure 8 FIG. 1 representatively shows a perspective view of a coupling guard 100 in another exemplary embodiment that can embody the principles of the present disclosure.

[0068] Different from Figure 2 or Figure 6In the embodiment shown, the avoidance portion is designed as a avoidance groove 131, as shown in FIG. Figure 8 As shown, in one embodiment of the present disclosure, the escape portion can be an escape hole 132. In this case, when assembling or disassembling the baffle 130, it is necessary to remove some moving parts (such as the shaft 210) to assemble or disassemble the baffle 130. Specifically, the baffle 130 can be moved relative to the shaft 210 in a first direction, allowing the shaft 210 to move relative to the escape hole 132, thereby achieving assembly or disassembly. Through the above-mentioned structural design, the present disclosure can achieve a complete circumferential envelope of the shaft 210 using a single escape portion of the baffle 130.

[0069] like Figures 1 to 5 As shown, in one embodiment of the present disclosure, the protective component 110 may be provided with an insertion hole 1103 near the second barrel opening 1102, and the peripheral edge of the baffle 130 may be provided with a protrusion 133, which is inserted into the insertion hole 1103. Through the above structural design, the present disclosure can achieve the positioning and assembly of the baffle 130 and the protective component 110 by utilizing the cooperation between the protrusion 133 and the insertion hole 1103, which has a simple structure and is easy to operate.

[0070] like Figures 3 to 5 As shown, based on the structural design of the protective component 110 being provided with a socket 1103 and the baffle 130 being provided with a protrusion 133, in one embodiment of the present disclosure, the periphery of the baffle 130 may be provided with four protrusions 133, and these protrusions 133 may be arranged at intervals along the circumference of the baffle 130. Furthermore, the protective component 110 may be provided with four sockets 1103, and these sockets 1103 may be arranged at intervals along the circumference of the protective component 110. Through the above structural design, the present disclosure can increase the insertion and positioning position of the baffle 130 and the protective component 110, further improving the assembly effect of the baffle 130 and the protective component 110. In other embodiments of the present disclosure, the periphery of the baffle 130 may also be provided with two, three, five, or more protrusions 133, and the protective component 110 may be provided with two, three, five, or more sockets 1103, and the present disclosure is not limited to this embodiment.

[0071] like Figures 1 to 5 As shown, based on the structural design that the protective component 110 is provided with the socket 1103 and the baffle 130 is provided with the protrusion 133, in one embodiment of the present disclosure, the number of the protrusion 133 and the socket 1103 can be equal and arranged in a one-to-one correspondence.

[0072] like Figures 3 to 5As shown, based on the structural design of the protective component 110 being provided with the sockets 1103 and the baffle 130 being provided with the protrusions 133, in one embodiment of the present disclosure, the protrusions 133 can be evenly arranged along the circumference of the baffle 130, and the sockets 1103 can be evenly arranged along the circumference of the protective component 110. On this basis, the number of sockets 1103 can be a positive integer multiple of the number of protrusions 133, for example, 2 times, 3 times, etc. Of course, the embodiment shown in the accompanying drawings adopts a design in which there are four protrusions 133 and four sockets 1103, that is, the number of sockets 1103 is 1 times the number of protrusions 133, which also conforms to the above design concept. Through the above structural design, when assembling the baffle 130 and the protective component 110, the operation of rotating and aligning the baffle 130 or the protective component 110 to align the protrusions 133 and the sockets 1103 can be reduced, thereby achieving flexible assembly of the baffle 130 and the protective component 110 in multiple positions, reducing the difficulty of assembly and reducing the workload. Furthermore, when the positive integer multiple is greater than or equal to 2, the baffle 130 needs to be provided with fewer protrusions 133 , and flexible assembly in multiple positions can be achieved, further reducing the complexity of the structure.

[0073] like Figure 1 and Figure 2 As shown, based on the structural design of the protective component 110 being provided with a socket 1103 and the baffle 130 being provided with a protrusion 133, in one embodiment of the present disclosure, when the avoidance portion of the baffle 130 is a avoidance groove 131 and there are two baffles 130, the two baffles 130 are stacked along a first direction, and the protrusions 133 of the two baffles 130 can be inserted into the same socket 1103. In other words, two protrusions 133 belonging to two baffles 130 are inserted into one socket 1103 of the protective component 110. For example, if each baffle 130 is provided with four protrusions 133, the protective component 110 is provided with four sockets 1103. Through this structural design, the present disclosure can utilize the same socket 1103 to simultaneously accommodate the protrusions 133 of different baffles 130, thereby reducing the number of sockets 1103 provided on the protective component 110, simplifying the structural complexity, and improving the structural strength of the protective component 110. Furthermore, the two baffles 130 are stacked to achieve a close fit between the baffles 130 , further enhancing the protective effect of the coupling protective cover 100 .

[0074] like Figure 2 As shown, based on the structural design of two baffles 130, in one embodiment of the present disclosure, the two baffles 130 can be components of the same structure. This structural design facilitates mass production of parts, and when assembling or replacing baffles 130, there is no need to identify which of the two baffles 130 is being replaced, further reducing operational difficulty.

[0075] like Figure 1 、 Figure 2 and Figure 5 As shown, in one embodiment of the present disclosure, the protective component 110 may include a first barrel 111 and a second barrel 112. Specifically, the barrel opening of the first barrel 111 at one end away from the motor 200 along the first direction is the above-mentioned first barrel opening 1101 of the protective component 110. The barrel opening of the second barrel 112 at one end close to the motor 200 along the first direction is the above-mentioned second barrel opening 1102 of the protective component 110, that is, the baffle 130 is provided on the second barrel 112. The other end of the second barrel 112 is telescopically connected to the other end of the first barrel 111 so that the length of the protective component 110 in the first direction is adjustable. Through the above-mentioned structural design, the present disclosure can realize the telescopic adjustment function of the protective component 110, realize the application of pumps 500 of different specifications, and further expand the scope of application of the coupling protective cover 100.

[0076] In one embodiment of the present disclosure, the baffle 130 may be manufactured by sheet metal stamping or laser cutting.

[0077] In one embodiment of the present disclosure, the retaining ring 120 may be manufactured by a sheet metal stamping process.

[0078] In one embodiment of the present disclosure, the first cylinder 111 may be manufactured by a sheet metal roll forming process.

[0079] In one embodiment of the present disclosure, the second cylinder 112 may be manufactured by a sheet metal roll forming process.

[0080] See Figure 9 As shown, Figure 9 FIG. 1 representatively shows a perspective view of a coupling guard 100 in another exemplary embodiment that can embody the principles of the present disclosure.

[0081] Different from Figure 1 、 Figure 6 or Figure 8 In the embodiment shown, the protective component 110 includes a first cylinder 111 and a second cylinder 112. Figure 9 As shown, in one embodiment of the present disclosure, the protective component 110 may include only one cylinder, which is not limited to the above embodiment.

[0082] It should be noted that the coupling guards shown in the drawings and described in this specification are only a few examples of the many types of coupling guards that can employ the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are in no way limited to any detail or any component of the coupling guard shown in the drawings or described in this specification.

[0083] Based on the above detailed description of several exemplary embodiments of the coupling guard 100 proposed in the present disclosure, an exemplary embodiment of the pump 500 proposed in the present disclosure will be described below.

[0084] like Figures 10 to 12 As shown, Figure 10 : A perspective schematic diagram of a pump 500 proposed in the present disclosure in an exemplary embodiment is representatively shown; Figure 11 Representatively shown in Figure 10 The schematic partial cross-sectional view of the pump 500 is shown, specifically showing the cross-sectional structure of the shaft 210 in the area of ​​the coupling guard 100; Figure 12 Representatively shown in Figure 11 Schematic diagram of the enlarged portion A.

[0085] like Figures 10 to 12 As shown, in one embodiment of the present disclosure, the pump 500 proposed in the present disclosure includes a motor 200, a bearing housing 300, and moving parts connected between the motor 200 and the bearing housing 300. The pump 500 proposed in the present disclosure further includes a coupling guard 100 proposed in the present disclosure and described in detail in the above embodiment, and the coupling guard 100 is used to envelop the moving parts.

[0086] As mentioned above, the installation method of the coupling protective cover 100 proposed in the present disclosure is roughly as follows: before installing the coupling 400, fix the retaining ring 120 on the tail end face of the bearing box 300. After the retaining ring 120 is fixed, install the coupling 400. After the second cylinder 112 is wrapped around the coupling 400, the two baffles 130 are stacked and the two avoidance grooves 131 are crossed at a certain angle (that is, the opening directions of the two avoidance grooves 131 are different) to form a channel and then fixed to the protective component 110. The two ends of the bottom opening of the second cylinder 112 are inserted and fixed and fastened with fasteners to prevent the bottom opening of the second cylinder 112 from popping open. After the first cylinder 111 is wrapped around the retaining ring 120 and the second cylinder 112, the bottom plates on both sides of the bottom opening of the first cylinder 111 are pre-tightened with fasteners.
