Description

Technical Field

[0001] The invention relates to the technical field of metal armored switch cabinets, and in particular to a switch cabinet door lock calibration tool and method. Background Art

[0002] KYN28 metal armored switchgear is an electric control equipment widely used in power systems. The opening and closing of its door panels is crucial to the normal operation and maintenance of the equipment.

[0003] In the prior art, the door lock system of the KYN28 metal armored switch cabinet usually includes two main components: a lock catch and a lock tongue. The lock catch is welded on the inside of the door panel, while the lock tongue is installed on the right front side panel. The door is locked by inserting the lock tongue into the lock catch and fixing it with a door pin. However, the lock catch is not easy to fix due to its structural problems. Each welding requires manual correction, and the error is large, which makes it difficult for the door pin to penetrate after welding. The lock tongue is fastened with a thread. After fastening, it cannot be guaranteed that the lock tongue is in a horizontal position. It needs to be manually knocked for correction. If the horizontal installation cannot be guaranteed, the door pin is not easy to penetrate, which eventually makes the door panel inflexible. Therefore, the labor intensity is increased when installing the lock catch and lock tongue, which also affects the installation accuracy and reliability of the door lock. Summary of the invention

[0004] In view of the deficiencies in the prior art, an embodiment of the present invention aims to provide a switch cabinet door lock calibration tool, the design of which aims to simplify the installation and calibration process of the door lock and improve the installation accuracy and ease of use of the switch cabinet door lock.

[0005] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0006] A switch cabinet door lock correction tool is used to correct a lock buckle and a lock tongue, the lock buckle is installed on the inner side of a door panel, and the lock tongue is installed on a side panel, the correction tool includes a positioning tool and a limiting tool; the positioning tool includes a positioning piece and a positioning rod, both ends of the positioning piece are provided with positioning grooves, the positioning grooves are clamped on the door panel and slidably installed, the positioning rod is arranged on the side of the positioning piece, and the positioning rod is inserted in the through hole of the lock buckle; the limiting tool includes a limiting piece and a stop plate, the limiting piece has a mounting portion, the mounting portion is clamped on the side of the side panel, the side of the mounting portion is provided with a groove, the stop plates are symmetrically installed on both sides of the groove, and a limiting cavity of the lock tongue is formed between the stop plates.

[0007] An embodiment of the present invention also provides a correction method for the switch cabinet door lock correction tool as described above, including: lock buckle correction: install the lock buckle on the inner side of the door panel, clamp the positioning groove of the positioning piece on both sides of the door panel, slide the positioning piece to insert the positioning rod into the through hole of the lock buckle, fix the lock buckle, then pull the positioning rod out of the lock buckle through hole, and remove the positioning piece; lock tongue correction: install the lock tongue on the end face of the side panel, install a nut on the back of the lock tongue, clamp the installation part of the limit piece on both sides of the side panel, so that the lock tongue is located in the limiting cavity, tighten the nut on the back of the lock tongue, and remove the limit piece.

[0008] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0009] 1. The positioning fixture of this embodiment is composed of a positioning piece and a positioning rod. The two ends of the positioning piece are provided with positioning grooves. When in use, the positioning grooves of the positioning piece are clamped on both sides of the door panel, and the positioning piece is slid so that the positioning rod is inserted into the through hole of the lock. By sliding and adjusting the positioning piece, it is possible to ensure that the lock is in a horizontal position. Subsequently, a welding operation is performed to ensure that the lock is firmly fixed to the inner side of the door panel.

[0020] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] As described in the background technology, it is difficult to ensure the horizontal position of the lock catch 3 during welding, which makes it difficult to insert the door pin 5. The lock tongue 4 cannot be kept horizontal after being tightened, and needs to be manually knocked and corrected, which adds extra labor and time costs. The prior art lacks an effective tool to assist the precise installation of the lock catch 3 and the lock tongue 4, which affects the opening flexibility and overall assembly quality of the switch cabinet door. In order to solve the above technical problems, the present invention proposes a switch cabinet door lock correction tool.

[0022] like Figure 1 As shown, the lock catch 3 is installed on the inner side of the door panel 2, the lock tongue 4 is installed on the side panel 1, and the door pin 5 passes through the lock catch 3 and the lock tongue 4 to achieve locking. The switch cabinet door lock calibration tool of this embodiment is used to calibrate the lock catch 3 and the lock tongue 4. The calibration tool includes a positioning tool and a limiting tool. Figure 2 , Figure 3As shown, the positioning tool comprises a positioning member 6 and a positioning rod 7. The two ends of the positioning member 6 are provided with positioning grooves 63. The positioning grooves 63 are clamped on the door panel 2 and slidably installed. The positioning rod 7 is arranged on the side of the positioning member 6 and inserted into the through hole of the lock buckle 3. Figure 4 , Figure 5 As shown, the limiting tooling includes a limiting member 8 and a stop plate 9, the limiting member 8 has a mounting portion, the mounting portion is clamped on the side of the side plate 1, a groove 84 is provided on the side of the mounting portion, the stop plates 9 are symmetrically installed on both sides of the groove 84, and a limiting cavity 91 of the lock tongue 4 is formed between the stop plates 9.

[0023] The positioning fixture of this embodiment is composed of a positioning member 6 and a positioning rod 7. Positioning grooves 63 are provided at both ends of the positioning member 6. The positioning grooves 63 are used to be clamped on the inner side of the door panel 2 and slidably installed. The positioning rod 7 can be inserted into the through hole of the lock catch 3 to achieve accurate positioning of the position of the lock catch 3. When in use, the positioning grooves 63 of the positioning member 6 are clamped on both sides of the door panel 2, and the positioning member 6 is slid so that the positioning rod 7 is inserted into the through hole of the lock catch 3. By sliding and adjusting the positioning member 6, it can be ensured that the lock catch 3 is in a horizontal position. Then, the welding operation is performed to ensure that the lock catch 3 is firmly fixed on the inner side of the door panel 2. After the welding is completed, the positioning rod 7 is pulled out and the positioning member 6 is removed. In this way, by using the positioning fixture, the position deviation of the lock catch 3 caused by manual operation can be effectively avoided, and the installation accuracy is improved.

[0024] The limiting fixture is composed of a limiting member 8 and a stop plate 9. The limiting member 8 has a mounting portion, which is fixed to the side of the side panel 1 by a clamping method. The stop plate 9 is installed on both sides of the groove 84 of the limiting member 8, and a cavity for limiting the position of the lock tongue 4 is formed between the two stop plates 9. When in use, the mounting portion of the limiting member 8 is clamped on both sides of the side panel 1 so that the lock tongue 4 is located in the limiting cavity 91 and maintains a horizontal position. The nut on the back of the lock tongue 4 is used to fasten the lock tongue 4 to the side panel 1. By using the limiting fixture, it can be ensured that the lock tongue 4 will not tilt during the tightening process, avoiding the operation steps that require manual knocking and correction in the traditional method, and ensuring the high precision of the horizontality of the lock tongue 4.

[0025] The positioning member 6 includes an end plate 61 and a positioning plate 62, and the end plate 61 and the positioning plate 62 are perpendicular to each other. The end plate 61 is located at the left and right ends of the positioning member 6, and the positioning plate 62 is located at the front and back sides of the positioning member 6. The end plate 61 is located on the inner side of the door panel 2, and the positioning plate 62 is located on the outer side of the door panel 2. The positioning rod 7 is installed on the positioning plate 62, and the axis of the positioning rod 7 is perpendicular to the positioning plate 62.

[0026] The end plates 61 are arranged on the left and right sides of the positioning member 6. They are in the shape of rectangular plates with appropriate thickness and high rigidity. The positioning plates 62 are located on the front and back sides of the positioning member 6 and are perpendicular to the end plates 61, ensuring good structural stability of the entire positioning member 6. During use, the end plates 61 are clamped in the slideways of the door panel 2 to ensure that the positioning member 6 can move smoothly during sliding without tilting or deviation. The positioning plates 62 are used to support and fix the positioning rod 7, enabling the positioning rod 7 to accurately insert into the hole of the lock catch 3 and ensuring the alignment accuracy between the lock catch 3 and the lock tongue 4 after welding.

[0027] Both sides of the end plate 61 have notches. The notches are located between the end plate 61 and the positioning plate 62 to form the positioning groove 63, providing a clamping position during the installation of the positioning member 6, enabling the positioning member 6 to be accurately installed in the slideway of the door panel 2, and providing necessary support and guidance when the positioning rod 7 inserts into the hole of the lock catch 3. The shape and size of the notches are precisely calculated to ensure that the positioning member 6 can slide smoothly in the slideway while maintaining the perpendicularity and stability of the positioning rod 7. The width of the positioning groove 63 is slightly larger than the width of the slideway, ensuring that the positioning member 6 can be easily installed and disassembled without affecting the stability of the positioning member 6.

[0028] Through holes are provided on the positioning plates 62. The positioning rod 7 is installed in the through holes of the two-side positioning plates 62, and both ends of the positioning rod 7 pass through the two-side positioning plates 62.

[0029] The through holes on the positioning plates 62 are designed as circular holes with a diameter matching that of the positioning rod 7 to ensure that the positioning rod 7 can be smoothly inserted. The positioning rod 7 is made of high-strength metal material, and both ends pass through the outside of the positioning plates 62, enabling the positioning rod 7 to provide sufficient support force during installation to ensure that the lock catch 3 remains horizontal during welding. Moreover, the positioning rods 7 at both ends can achieve the positioning of the double-side lock catch 3, and welding of the lock catches 3 at two positions can be completed by installing the positioning member 6 once, improving work efficiency.

[0030] As Figure 4 、 Figure 5 shown, the installation part of the limiting member 8 includes an installation plate 83 and a limiting plate 82. The limiting plates 82 are located on both sides of the installation plate 83. The limiting plates 82 and the installation plate 83 form a U-shaped structure, and the two-side limiting plates 82 are attached to both sides of the side plate 1. The installation part is fixed to the side plate 1 by a clamping method, and the limiting plates 82 are attached to both sides of the side plate 1 to ensure accurate positioning of the lock tongue 4 during installation.

[0031] The anti-rotation plate 9 includes a horizontal plate and a vertical plate, and the horizontal plate and the vertical plate form an L-shaped structure. The vertical plates of the two anti-rotation plates 9 are installed on the mounting plate 83 and are located on both sides of the groove 84. A limiting cavity 91 is formed between the horizontal plates of the two anti-rotation plates 9. The design of the limiting cavity 91 ensures that the lock tongue 4 can be accurately positioned during installation, preventing the lock tongue 4 from rotating during the installation process. The width of the limiting cavity 91 is precisely designed so that the lock tongue 4 can be firmly fixed in the cavity, thereby ensuring the horizontal installation of the lock tongue 4 and improving the installation accuracy and service life of the door lock.

[0032] The position-limiting member 8 also includes a gripping portion 81, which is disposed on the top of the mounting portion. The gripping portion 81 is an L-shaped plate, which is disposed on the top of the mounting plate 83. The gripping portion 81 provides an operator with a convenient position for grasping and adjusting when using the position-limiting member 8, thereby improving the convenience of operation of the tooling. The design of the L-shaped plate enables the gripping portion 81 to have good rigidity and stability, and can withstand multiple operations during use. The gripping portion 81 is of moderate size, which can adapt to the palm size of different operators and ensure comfort during operation.

[0033] The positioning member 6 and the stopper 8 are both sheet metal bending members, made of high-quality steel, and have a stable structure through a bending process, with a simple manufacturing process and low production cost, which is suitable for large-scale production and application.

[0034] The correction tool can ensure that the lock buckle 3 is horizontal when welding, and the door pin 5 can be inserted vertically after welding. It can also ensure the horizontal position of the lock tongue 4 after fastening, and the door pin 5 can be inserted vertically. The labor efficiency is improved, and the welding accuracy and assembly accuracy are guaranteed. The structure is simple, and the tool does not need to be fastened during operation, which is convenient to use and reduces labor intensity.

[0035] The calibration method of the switch cabinet door lock calibration tool comprises:

[0036] Correction of the lock catch 3: Install the lock catch 3 on the inner side of the door panel 2, clamp the positioning grooves 63 of the positioning member 6 on both sides of the door panel 2, slide the positioning member 6, and insert the positioning rod 7 into the through hole of the lock catch 3 (such as Figure 3 As shown), weld the lock buckle 3, then pull out the positioning rod 7 from the through hole of the lock buckle 3, and remove the positioning piece 6;

[0037] Correction of the lock tongue 4: Install the lock tongue 4 on the end face of the side plate 1, install a nut on the back of the lock tongue 4, and clamp the mounting portion of the limiter 8 on both sides of the side plate 1 so that the lock tongue 4 is located in the limit cavity 91 (such as Figure 5 As shown), tighten the nut on the back of the locking tongue 4 and remove the limiting piece 8.

[0038] The correction method can ensure the horizontal position of the lock catch 3 and the lock tongue 4 during the welding and fastening process, simplify the operation process, reduce labor intensity, and improve the accuracy of welding and assembly, thereby improving the reliability and convenience of the switch cabinet door lock. Through the correction method, more efficient and accurate door lock installation can be achieved, ensuring the flexible opening and closing of the door panel 2, improving the operation and maintenance efficiency of the power system, and improving the installation quality and service life of the switch cabinet door lock.

[0039] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
