Description

Technical Field

[0001] The present application relates to the technical field of fasteners, and in particular to a fastener for assembling an electrical cabinet. Background Art

[0002] At present, in the process of assembling circuit elements inside the electrical cabinet, fasteners are usually used to install and fix the circuit elements. In order to ensure that the circuit elements can be successfully installed in the electrical cabinet, the installation position of the circuit elements needs to be determined in advance before assembly, and then a mounting hole is opened at a specified position on the inner wall of the electrical cabinet. During assembly, the fasteners are passed through the circuit elements and the mounting holes in sequence, and the circuit elements can be pressed and fixed in the electrical cabinet by tightening the fasteners.

[0003] Regarding the above installation method, since in the actual assembly process, the installation position of the circuit components will inevitably have a certain deviation, once the installation position of the circuit components deviates, it will directly lead to the inability of the fasteners to be smoothly aligned with the reserved installation holes. Therefore, there are great limitations. At the same time, the accuracy requirements for the assembly position are high, and the installation difficulty is also greater. Utility Model Content

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] An embodiment of the present application discloses a fastener for assembling an electrical cabinet.

[0024] Reference Figure 1 , Figure 2 The electrical cabinet assembly fasteners include a fixing seat 1, a bolt column 2 and a wire pressing plate 3. A threaded hole 10 is provided on one side of the fixing seat 1, and the tail of the bolt column 2 is used to be inserted and threadedly connected in the threaded hole 10. A limiting groove 11 is provided on the outer wall of the fixing seat 1. The limiting groove 11 is circumferentially arranged on the outer circumference of the fixing seat 1. The fixing seat 1 is limited by the limiting groove 11 and is slidably set in the installation track of the electrical cabinet. In this embodiment, the shape of the fixing seat 1 is roughly a rectangular parallelepiped, and the outer wall of the fixing seat 1 set in the installation track is in contact with the inner wall of the installation track, and the fixing seat 1 is used to be slidably set in the electrical cabinet along the length direction of the installation track.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a guide groove 12 is provided on the outer wall of the fixing seat 1 away from the opening surface of the threaded hole 10. The guide groove 12 is used to be plugged and matched with the slide rail provided on the inner wall of the mounting track, and the shape of the guide groove 12 is adapted to the shape of the slide rail in the mounting track. The provision of the limit groove 11 and the guide groove 12 can further enhance the stability of the fixing seat 1 in the mounting track, ensuring that the fixing seat 1 can stably slide along the length direction of the mounting track. Chamfered corners 13 are provided at the four corners of the outer wall of the fixing seat 1. When the fixing seat 1 is moved from the opening on one side of the mounting track into the mounting track, the guidance of the chamfered corners 13 can ensure that the fixing seat 1 is inserted into the mounting track more smoothly.

[0026] like Figure 2 , Figure 3 As shown, the wire pressing plate 3 is used to be sleeved on the outside of the bolt column 2. The wire pressing plate 3 has a plurality of through holes 30 for the bolt column 2 to pass through, and adjacent through holes 30 are arranged in sequence along the length direction of the wire pressing plate 3. The head of the bolt column 2 screwed on the fixing seat 1 is used to press the wire pressing plate 3 against the outer wall of the fixing seat 1 and the mounting track.

[0027] like Figure 2 , Figure 3As shown, a wire pressing groove 31 is provided on the side wall of the wire pressing plate 3 facing the fixing seat 1, and the length of the wire pressing groove 31 extends along the length direction of the wire pressing plate 3. The wire pressing groove 31 is used for inserting external cables. When the bolt column 2 tightens the wire pressing plate 3 on the outer wall of the fixing seat 1, the external cables in the wire pressing groove 31 will be limited and pressed on the outer wall of the mounting track, thereby further optimizing the layout of the external cables and making the layout of the external cables more reasonable and orderly.

[0028] like Figure 2 , Figure 3 As shown, a circumferentially surrounding polished rod segment 20 is formed on the outer circumferential surface of the bolt column 2, and a circumferentially surrounding polished surface segment 14 is also formed on the inner side wall of the threaded hole 10, and the polished surface segment 14 is used for the polished rod segment 20 to rotate in the fixing seat 1. When wiring the external cable, the bolt column 2 is gradually screwed out of the threaded hole 10 until the tail of the bolt column 2 located on one side of the polished rod segment 20 enters the polished surface segment 14, and at this time, the threaded portion of the bolt column 2 located on the other side of the polished rod segment 20 will be disengaged from the threaded hole 10. In the above state, the tail of the bolt column 2 can rotate freely in the polished surface segment 14, and at the same time, the tail of the bolt column 2 can be limited in the polished surface segment 14, so as to prevent the bolt column 2 from being disengaged from the threaded hole 10. When the bolt column 2 needs to be completely removed from the threaded hole 10, the bolt column 2 is pulled outward until the external thread at the rear of the bolt column 2 is threadedly engaged with the internal thread of the threaded hole 10 again, and the bolt column 2 can then be smoothly screwed out of the threaded hole 10.

[0029] The implementation principle is: when the bolt column 2 has not yet fixed the fixing seat 1 set in the installation track, the installation position of the fixing seat 1 can be slid along the length direction of the installation track. After the fixing seat 1 is moved to the desired position, the circuit element to be installed is tightened and fixed to the outside of the installation track through the bolt column 2, and the circuit element can be fixedly installed on the outside of the installation track. When it is necessary to limit the position of the external cable on the circuit element, the wire pressing plate 3 can be set on the outside of the bolt column 2, and the external cable can be placed in the wire pressing groove 31, and finally the bolt column 2 can be tightened. The tightened bolt column 2 can press the wire pressing plate 3 on the outer wall of the fixing seat 1 and the installation track, thereby completing the installation of the external cable of the circuit element. Compared with the traditional hole opening method, the installation range is further increased, the assembly work is convenient, and the accuracy requirement for the assembly position is low, thereby ensuring the smooth progress of the assembly work.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
