A multi-layer scalable electrical control cabinet

Abstract

This utility model relates to the field of electrical control cabinet technology and provides a multi-layer expandable electrical control cabinet, including a base cabinet and a locking mechanism. The locking mechanism is located on one side of the base cabinet surface, and a top cover is installed on the other side of the locking mechanism. The multi-layer expandable electrical control cabinet provided by this solution, through the locking mechanism, allows for easy extension of the cabinet body. First, the top cover is removed. Then, the module cabinet and the base cabinet are aligned, allowing the locking block to be inserted into the fitting groove. During insertion, the locking block presses against the limiting block, causing the limiting block to overcome the spring force and slide in the groove. When one end of the locking block is in contact with the fitting groove, the spring provides elasticity, ensuring a stable limiting engagement between the limiting block and the locking block, guaranteeing initial installation of the module cabinet. Subsequent rigid installation can be completed by tightening bolts. Finally, the top cover is fixed using the same threaded bolts and locking structure as the module cabinet, completing the overall installation.

[0018] This utility model embodiment provides a multi-layer expandable electrical control cabinet, such as... Figure 1-5 As shown, the multi-layer expandable electrical control cabinet includes a base cabinet 1 and a locking mechanism 2. The locking mechanism 2 is provided on one side of the surface of the base cabinet 1, and a top cover 3 is installed on the other side of the locking mechanism 2. The engaging mechanism 2 includes a module cabinet 201, a threaded bolt 202, an engaging block 203, a threaded groove 204, a bolt 205, a fitting groove 206, a sliding groove 207, an installation groove 208, a spring 209, a connecting block 210, and a limiting block 211. The module cabinet 201 is attached to the top surface of the base cabinet 1. Threaded bolts 202 are installed on both side walls of the base cabinet 1. The engaging block 203 is fixedly connected to the top of the base cabinet 1. Threaded grooves 204 are opened on the lower side of both side walls of the module cabinet 201. Bolts 205 are connected to the internal threads of the threaded bolts 202. A fitting groove 206 is opened on one side of the bottom end of the module cabinet 201. Sliding grooves 207 are opened on both side walls of the fitting groove 206. An installation groove 208 is opened on the other side of the sliding groove 207.

A limiting block 211 is connected to the other side of the connecting block 210.

[0019] In this embodiment, during normal use, the base cabinet 1 is used as a normal control cabinet, and a top cover 3 is installed on the top to ensure the airtightness of the cabinet. When it is necessary to extend the cabinet, the top cover 3 is first removed, and then the module cabinet 201 is aligned with the base cabinet 1, so that the locking block 203 is inserted into the fitting groove 206. During the insertion process, the locking block 203 will press the limiting block 211, so that the limiting block 211 overcomes the force of the spring 209 and slides in the sliding groove 207. When one end of the locking block 203 is in contact with the fitting groove 206, the spring 209 provides a continuous elastic force, so that the limiting block 211 is always in an outward pushing state, thereby forming a stable limiting engagement relationship with the locking block 203, ensuring the initial installation of the module cabinet 201. After that, the subsequent rigid installation can be completed by tightening the bolts 205. Finally, the top cover 3 is fixed by the same threaded bolts 202 and locking structure as the module cabinet 201, forming a symmetrical and stable overall combination structure.

[0020] In a further preferred embodiment of the present invention, one end of the bolt 205 is threaded into the threaded groove 204, and the module cabinet 201 is rigidly connected to the base cabinet 1 by the bolt 205.

[0021] In this embodiment, the bolt 205 is threaded into the threaded groove 204 to rigidly fix the module cabinet 201 to the base cabinet 1, ensuring that the overall structure is stable and does not loosen.

[0022] In a further preferred embodiment of the present invention, a top cover 3 is tightly fitted to the top of the module cabinet 201, and a threaded bolt 202 and a locking block 203 are also installed on the top of the module cabinet 201. A locking component is also installed inside the top cover 3.

[0023] In this embodiment, the top cover 3 is installed on the top of the module cabinet 201 to enclose and protect the internal components of the module cabinet 201, and to achieve a stable connection with the module cabinet 201 through the snap-fit ​​component, thereby enhancing the overall structural integrity.

[0024] In a further preferred embodiment of the present invention, the locking block 203 and the fitting groove 206 are positioned opposite each other, and the end of the locking block 203 is hexagonal.

[0025] In this embodiment, the locking block 203 is disposed on the base cabinet 1 and the module cabinet 201, and is used to insert into the fitting groove 206 to form a sliding locking structure with the limiting block 211, thereby realizing the rapid positioning and stable locking of the module cabinet 201.

[0026] In a further preferred embodiment of the present invention, the end of the limiting block 211 is tapered, and the limiting block 211 forms a mutually sliding and engaging structure with the engaging block 203 through the spring 209 and the connecting block 210.

[0027] In this embodiment, the limiting block 211 is fitted into the slide groove 207 and is pushed by the spring 209 and the connecting block 210, cooperating with the locking block 203 to play a limiting and fixing role, preventing the module cabinet 201 from loosening or shifting.

[0028] In a further preferred embodiment of the present invention, the main body of the connecting block 210 is engaged in the mounting groove 208, and the connecting block 210 and the mounting groove 208 form a mutual sliding structure through the spring 209.

[0029] In this embodiment, the mounting groove 208 is used to accommodate the connecting block 210. The connecting block 210 cooperates with the spring 209 to push the limiting block 211, thereby realizing the sliding positioning function of the limiting block 211 and ensuring the stability and reliability of the locking structure.

[0030] In a further preferred embodiment of the present invention, the main body of the limiting block 211 is fitted into the slide groove 207, and the limiting block 211 and the slide groove 207 form a mutual sliding structure through the spring 209 and the connecting block 210.

[0031] In this embodiment, the slide groove 207 is provided on both sides of the fitting groove 206 to guide the sliding of the limiting block 211. Together with the connecting block 210 and the spring 209, the limiting block 211 is accurately positioned and engaged.

[0032] In a further preferred embodiment of the present invention, the threaded bolt 202 and the threaded groove 204 are positioned opposite each other, and the threaded bolt 202 and the threaded groove 204 are symmetrically distributed along the base cabinet 1 and the module cabinet 201.

[0033] In this embodiment, the threaded bolt 202 and the threaded groove 204 cooperate with the internal connecting bolt 205 to achieve threaded fastening between the module cabinet 201 and the base cabinet 1, thereby enhancing the overall connection strength and stability.

[0034] In summary, during normal use, the base cabinet 1 is used as a normal control cabinet, with the top cover 3 installed on top to ensure the cabinet's airtightness. When it is necessary to extend the cabinet, the top cover 3 is first removed, and then the module cabinet 201 is aligned with the base cabinet 1, so that the locking block 203 is inserted into the fitting groove 206. During the insertion process, the locking block 203 will press against the limiting block 211, which will overcome the force of the spring 209 and slide in the slide groove 207. When one end of the locking block 203 is in contact with the fitting groove 206, the spring 209 provides continuous elastic force, so that the limiting block 211 is always in an outward pushing state, thus forming a stable limiting engagement relationship with the locking block 203, ensuring the initial installation of the module cabinet 201. After that, the subsequent rigid installation can be completed by tightening the bolts 205. Finally, the top cover 3 is fixed by the same threaded bolts 202 and locking structure as the module cabinet 201, forming a symmetrical and stable overall combination structure.
