Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switch cabinets, in particular to a front middle door of a switch cabinet. Background Art
[0002] The production workshop of the front middle door of the KYN28 cabinet reported that it was difficult to close the door and could not meet the requirements of mass production. It was necessary to improve the installation method of the front middle door lock. The existing lock block was installed and fixed on the third folding edge of the front door. This method could not ensure the position and size of the lock block when subjected to great force, making it difficult for subsequent owners to close the front middle door, or even impossible to close it, which would create hidden dangers. Utility Model Content
[0003] The purpose of the utility model is to solve the above technical problems and provide a front middle door of a switch cabinet.
[0004] The technical solution of the utility model: a front middle door of a switch cabinet, comprising a front middle door body and a locking block, the front middle door body being respectively provided with a first folded edge, a second folded edge, a third folded edge and a fourth folded edge, characterized in that: a positioning groove is provided on the second folded edge, a through groove is provided on the third folded edge, the positioning groove is communicated with the through groove, one end of the locking block passes through the positioning groove and contacts with the first folded edge, and the bottom of the locking block passes through the through groove and is connected with the front middle door body.
[0005] Preferably, one end of the locking block passing through the positioning groove does not contact the positioning groove.
[0006] Preferably, the third folded edge is provided with a plurality of welding point grooves communicating with the through groove.
[0007] The beneficial effects of the utility model are as follows: in the utility model, by adding a positioning groove at the third folding edge of the front middle door and using it as the installation reference of the lock block, it can be ensured that the lock block is fully fixed to the front surface of the front middle door through the welding point, which can effectively ensure that it is not damaged when subjected to strong force; by optimizing the welding point groove, the welding time is greatly shortened and the adsorption force between the lock block and the front middle door is improved.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Reference Figures 1 to 5 A front middle door of a switch cabinet comprises a front middle door body 10 and a locking block 2, wherein the front middle door body 10 is respectively provided with a first folding edge 101, a second folding edge 102, a third folding edge 103 and a fourth folding edge 104, characterized in that: a positioning groove 1021 is provided on the second folding edge 102, a through groove 1031 is provided on the third folding edge 103, the positioning groove 1021 is communicated with the through groove 1031, one end of the locking block 2 passes through the positioning groove 1021 and contacts with the first folding edge 101, and the bottom of the locking block 2 passes through the through groove 1031 and is connected with the front middle door body 10. In the present invention, a positioning groove 1021 is set on the second folded edge 102, and one end of the lock block 2 passes through the positioning groove 1021 and contacts with the first folded edge 101 as the installation reference of the lock block 2, which can effectively reduce the error caused by the bending process. The lock block 2 is welded to the front middle door body 10 to ensure that the lock block 2 is fully fixed to the front surface of the front middle door body 10 through the welding point, which can effectively ensure that it is not damaged when subjected to strong force. The problem that the upper and lower positioning references of the lock block 2 were previously the third folded edge 103 and welded thereto, and the third folded edge 103 and the fourth folded edge 104 were separated, so when the lock block 2 is subjected to the upward F force of the lock buckle, the third folded edge 103 and the fourth folded edge 104 will be separated, and the upper and lower positions of the lock buckle 2 cannot be guaranteed, resulting in difficulty in closing the door.
[0016] As a preferred embodiment of the utility model, it may also have the following additional technical features:
[0017] In this embodiment, one end of the locking block 2 passing through the positioning groove 1021 does not contact the positioning groove 1021. Due to processing errors, the locking block 2 does not contact the positioning groove 1021, and a processing error gap is reserved to prevent interference and difficulty in closing the door.
[0018] In this embodiment, a plurality of welding point grooves 1032 communicating with the through grooves 1031 are provided on the third folded edge 103 to improve the stability of welding between the locking block 2 and the front middle door body 10 .
[0019] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
