For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] This embodiment provides a hole position correction member, such as Figure 1-Figure 6 As shown, the hole correction piece includes a positioning sticker 100, which is arranged at the end of the connecting rod 10, and after the cabinet door is closed, the positioning sticker 100 can be attached to the inner side of the cabinet door, and the positioning sticker 100 is provided with a first group of hole position identification lines 110 and a second group of hole position identification lines 120, and the center point of the second group of hole position identification lines 120 is located in the preset direction of the center point of the first group of hole position identification lines 110, and the angle between the preset direction and the horizontal direction is greater than 0° and less than 180°, that is, the second group of hole position identification lines The center point of 120 is located in the upper area of ​​the center point of the first group of hole position identification lines 110, so that after the connecting rod 10 of the operating mechanism is deflected, a hole is opened at the position marked by the second group of hole position identification lines 120 to correct the influence of gravity; the hole position correction part sets the hole positions of the first group of hole position identification lines 110 without the action of gravity and the second group of hole position identification lines 120 under the influence of correction gravity on the positioning sticker 100, which is used to assist in drilling holes on the cabinet door, avoid the position deviation of the holes on the cabinet door, and save the time of hole position correction.

[0044] Optionally, the installation direction of the operating mechanism is at an angle of 90° to the horizontal direction, that is, the operating mechanism is vertically installed in the switch cabinet, such as Figure 1 As shown, the center point of the second group of hole position identification lines 120 is located in the preset direction of the first group of hole position identification lines 110, and the angle between the preset direction and the horizontal direction is 90°. When the connecting rod 10 has no deflection, a hole is drilled at the position marked by the first group of hole position identification lines 110, and the external operating member 20 is installed; when the connecting rod 10 is subjected to its own gravity, the end of the connecting rod 10 sags. In order to avoid the problem of increased movement force of the operating mechanism due to the deviation of the connecting rod 10, a hole is drilled at the position marked by the second group of hole position identification lines 120 to install the external operating member 20, thereby lifting the end of the connecting rod 10 upward, thereby effectively reducing or eliminating the problem of unsmooth movement of the operating mechanism caused by the deviation of the connecting rod 10; the hole correction part is simple to install, and is automatically attached to the inside of the cabinet door when the cabinet door is closed. When the cabinet door is opened, a hole can be manually selected at the marked position of the first group of hole position identification lines 110 or the second group of hole position identification lines 120 according to the deflection of the connecting rod 10, thereby reducing the subsequent adjustment and correction work caused by positioning deviation, thereby saving time and labor costs.

[0045] In an optional embodiment, the installation direction of the operating mechanism is at an angle of 45° to the horizontal direction, that is, the operating mechanism is installed in the switch cabinet tilted to the right. Figure 2 As shown, the center point of the second group of hole position identification lines 120 is located in the preset direction of the first group of hole position identification lines 110. At this time, the angle between the preset direction and the horizontal direction is 45°. After the connecting rod 10 of the operating mechanism is deflected, a hole is opened at the position marked by the second group of hole position identification lines 120 to correct the influence of gravity.

[0046] In another optional embodiment, the installation direction of the operating mechanism is at an angle of 135° to the horizontal direction, that is, the operating mechanism is installed in the switch cabinet tilted to the left. Figure 3 As shown, the center point of the second group of hole position identification lines 120 is located in the preset direction of the first group of hole position identification lines 110. At this time, the angle between the preset direction and the horizontal direction is 135°. After the connecting rod 10 of the operating mechanism is deflected, a hole is opened at the position marked by the second group of hole position identification lines 120 to correct the influence of gravity.

[0047] It should be noted that the center point of the second group of hole position identification lines 120 is located in the preset direction of the center point of the first group of hole position identification lines 110. The preset direction here is related to the actual use environment of the operating mechanism. If the operating mechanism is used vertically, then the preset direction is also vertical. If the operating mechanism is used at an angle, then the preset direction must also be tilted accordingly.

[0048] Alternatively, if Figure 1 As shown, the first group of hole position identification lines 110 includes a connecting rod center positioning hole marking line 111 and an external operating component installation circular hole marking line 112. The connecting rod center positioning hole marking line 111 is directly opposite to the axis of the connecting rod 10, and the external operating component installation circular hole marking line 112 is coaxial with the connecting rod center positioning hole marking line 111. The connecting rod center positioning hole marking line 111 is directly opposite to the axis of the connecting rod 10, which can ensure that the positioning sticker 100 is correctly positioned relative to the connecting rod 10, and the external operating component installation circular hole marking line 112 is coaxial with the connecting rod center positioning hole marking line 111, which ensures that when the connecting rod 10 deflects without gravity, the external operating component 20 is connected to the connecting rod 10 to ensure that the external operating component 20 controls the operating mechanism smoothly.

[0049] Optionally, the first group of hole position identification lines 110 also includes a first mounting hole marking line 113, and multiple first mounting hole marking lines 113 are evenly arranged along the circumference of the connecting rod center positioning hole marking line 111. The spacing between two adjacent first mounting hole marking lines 113 is equal to the spacing between two adjacent fixing holes 21 on the external operating component 20, which can ensure the consistency of the hole opening position on the cabinet door and the spacing between adjacent fixing holes 21 on the external operating component 20, thereby ensuring that the external operating component 20 is stably installed on the cabinet door.

[0050] It should be noted that the external operating part 20 in the present embodiment is an operating handle, which is provided with a circular boss 22 and a fixing hole 21. The purpose of opening the mounting circle of the external operating part 20 is to match the circular boss 22 on the handle. The opening position of the first mounting hole marking line 113 corresponds one-to-one with the opening position of the fixing hole 21 on the operating handle, ensuring that the operating handle is stably fixed on the cabinet door.

[0051] Alternatively, if Figure 1 As shown, the second group of hole position identification lines 120 includes a correction center positioning hole marking line 121 and a correction installation circular hole marking line 122. The correction center positioning hole marking line 121 is located in the preset direction of the connecting rod center positioning hole marking line 111. The distance between the center of the correction center positioning hole marking line 121 (i.e., the center point of the second group of hole position identification lines 120) and the center of the connecting rod center positioning hole marking line 111 (i.e., the center point of the first group of hole position identification lines 110) is H, and H is greater than or equal to 0 and less than the radius of the external operating part installation circular hole marking line 112; the correction installation circular hole marking line 122 is concentric with the correction center positioning hole marking line 121, and the correction installation circular hole marking line 122 is the same size as the external operating part installation circular hole marking line 112. The setting of the second group of hole position identification lines 120 allows the position of the opening on the cabinet door to be corrected when the connecting rod 10 is affected by its own gravity. The correction center positioning hole mark 121 is located in the preset direction of the connecting rod center positioning hole mark 111, and the distance between its center and the center of the connecting rod center positioning hole mark 111 is H, H is greater than or equal to 0, and less than the radius of the external operating part installation hole mark 112. By limiting the upward movement distance range of the correction center positioning hole mark 121, the problem of poor movement of the operating mechanism due to excessive correction is avoided. Such a design takes into account the rationality and practicality of the correction and ensures the normal operation of the operating mechanism.

[0052] Optionally, the second group of hole position identification lines 120 also includes second mounting hole marking lines 123, and multiple second mounting hole marking lines 123 are evenly arranged along the circumference of the correction center positioning hole marking line 121, and the spacing between two adjacent second mounting hole marking lines 123 is equal to the spacing between two adjacent fixing holes 21 on the external operating part 20, thereby ensuring the consistency of the hole positions of the mounting holes on the cabinet door after correction and the hole positions of the fixing holes 21 on the external operating part, ensuring that the external operating part is firmly fixed on the cabinet door.

[0053] Alternatively, if Figure 4-Figure 6As shown, the connecting rod 10 includes a rod body 11 and a linkage shaft 12. The linkage shaft 12 is arranged at one end of the rod body 11 close to the cabinet door. The linkage shaft 12 is coaxial with the rod body 11. An operating rod 13 perpendicular to the linkage shaft 12 is arranged on the linkage shaft 12. It is defined that when the operating rod 13 is placed vertically, half of the distance between the highest point and the lowest point of the operating rod 13 is the radius of the operating center circle of the linkage shaft. H = the radius of the installation circle of the external operating part - the radius of the operating center circle in the deflection state of the linkage shaft - the error, and the error is 2mm-3mm. Specifically, when designing the hole position, the deflection force (the gravity of the connecting rod 10) received by each type of connecting rod 10 is known. According to the deflection force received by the connecting rod 10, the distance W of the end of the connecting rod 10 offset from the horizontal position and the offset angle of the connecting rod 10 can be calculated. The specific calculation process is as follows:

[0054]

[0055] F is the deflection force on the connecting rod; L is the deflection length; E is the elastic modulus; I is the moment of inertia. It can be understood that the deflection force on the connecting rod is the weight of the connecting rod, and the deflection length of the connecting rod is the length of the connecting rod.

[0056] The angle of the deflection can be calculated using trigonometric functions:

[0057]

[0058] The angle can be calculated to simulate the actual state of the connecting rod 10 when it is deflected, and half of the distance between the highest point and the lowest point of the operating rod 13 on the linkage shaft 12 is taken as the operation center circle radius of the linkage shaft 12. The obtained operation center circle radius of the linkage shaft in the deflected state is substituted into the formula for calculating H to obtain the H value, thereby determining the position of the center point of the second group of hole position identification lines 120 on the positioning sticker 100, and designing the correction installation circular hole marking line 122 and the positions of multiple second installation hole marking lines 123 around the center point of the second group of hole position identification lines 120.

[0059] Optionally, the two ends of the operating rod 13 are respectively provided with a first arc surface and a second arc surface, the external operating member 20 is provided with a cross-shaped hole 23, and the operating rod 13 is inserted into the cross-shaped hole 23. The design of the first arc surface and the second arc surface makes it easier for the two ends of the operating rod 13 to fit with the external operating member 20, and the assembly is smoother, which reduces the difficulty and resistance of assembly and improves the efficiency of assembly.

[0060] Optionally, when the linkage shaft 12 is in the deflection state and the operating rod 13 is placed vertically, half of the distance between the highest point of the first arc surface and the lowest point of the second arc surface is the radius of the operating center circle of the linkage shaft 12 in the deflection state. Therefore, the larger the deflection angle of the linkage shaft 12, the smaller the radius of the operating center circle of the linkage shaft 12, and the maximum radius of the operating center circle of the linkage shaft 12 is half of the length of the operating rod 13 when there is no deflection. By controlling the size of the operating center circle of the linkage shaft 12, the stability of the connecting rod 10 in different states is ensured, the instability and operating difficulties caused by the deflection of the connecting rod 10 are reduced, and the reliability and safety of the operation are improved.

[0061] Optionally, the linkage shaft 12 is detachably connected to the rod body 11, and the detachable connection between the linkage shaft 12 and the rod body 11 makes it more convenient when maintenance or replacement is required. For example, when the operating rod 13 or the linkage shaft 12 is damaged or needs to be replaced, it is only necessary to disassemble the connection without disassembling the entire operating mechanism, saving the time and workload required for maintenance and replacement.

[0062] Specifically, one end of the linkage shaft 12 away from the operating rod 13 is inserted into the rod body 11 and the rod body 11 and the linkage shaft 12 are locked by screws. The linkage shaft 12 is fixed to the rod body 11 by screws, which can ensure that the connection between the linkage shaft 12 and the rod body 11 is firm and reliable, and is not easy to loosen or fall off, thereby improving the stability and reliability of the operating mechanism. When the linkage shaft 12 needs to be replaced, they can be separated by removing the screws, which improves the convenience of maintenance.

[0063] Optionally, the first adhesive layer and the second adhesive layer are respectively provided on the two opposite sides of the positioning sticker 100, the first adhesive layer is attached to the end of the connecting rod 10, and the second adhesive layer is attached to the inner side of the cabinet door. It is understandable that the contact area between the end of the connecting rod 10 and the positioning sticker 100 is much smaller than the contact area between the positioning sticker 100 and the cabinet door, so the end of the connecting rod 10 is attached to the first adhesive layer. When the cabinet door is closed, there is a nearly vertical contact pressure between the end of the connecting rod 10 and the cabinet door. The positioning sticker 100 is attached to the inner side of the cabinet door with the help of the second adhesive layer. When the cabinet door is opened, the positioning sticker 100 is left on the inner side of the cabinet door due to the difference in contact area. After the installer determines whether the operating rod 13 is deflected, he can directly select the first group of hole position identification lines 110 or the second group of hole position identification lines 120 to open the hole. The hole position correction process is simple, saving time and effort.

[0064] Optionally, a connecting rod pasting identification frame 130 is provided on one side of the positioning sticker 100 provided with the first adhesive layer, the center point of the connecting rod pasting identification frame 130 coincides with the center point of the first group of hole position identification lines 110, and the end of the connecting rod 10 is pasted in the connecting rod pasting identification frame 130. By providing the connecting rod pasting identification frame 130, the pasting position of the connecting rod 10 can be located, ensuring that the positioning sticker 100 is quickly pasted on the end of the connecting rod 10, thereby improving installation efficiency.

[0065] Optionally, the first adhesive layer is disposed in the connecting rod pasting mark frame 130, which can save adhesive materials and further save costs. In other embodiments, the first adhesive layer can be disposed on the surface of the positioning sticker 100 where the connecting rod pasting mark frame 130 is located. Since the first adhesive layer has a large attachment area, it is convenient to dispose the first adhesive layer on the positioning sticker 100, reduce the manufacturing process of the positioning sticker 100, and improve the manufacturing efficiency of the positioning sticker 100.

[0066] The present embodiment also provides a switch cabinet, which includes a cabinet body, a cabinet door, an operating mechanism, a connecting rod 10 and the above-mentioned hole position correction piece, wherein the operating mechanism is arranged in the cabinet body, one side of the cabinet door is hinged to the cabinet body, one end of the connecting rod 10 is connected to the operating mechanism, and the other end is hung with a hole position correction piece, and when the cabinet door is closed, the hole position correction piece is attached to the inner side of the cabinet door. The switch cabinet uses the above-mentioned hole position correction piece to assist in drilling holes on the cabinet door, avoid the position deviation of the holes on the cabinet door, save the hole position correction time, and improve the assembly efficiency of the switch cabinet.

[0067] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
