[0025] Through the above structure, the guide rail can be directly fixed in the electrical cabinet by using multiple mounting holes 14, and the guide rails 3 extending conveniently on both sides are easy to adjust.
[0026] Combined with attachment Figure 4 and attached Figure 5 The guide rail 3 is inserted into the groove 2, and the guide rail 3 and the guide rail base 1 are fixed and locked together by locking bolts 5 and nuts 6. The guide rail base 1 and the guide rail 3 are provided with multiple fixing holes 4 for use with the locking bolts 5.
[0027] Through the above structure, the guide rail 3 is inserted into the groove 2, and the locking bolt 5 is used to pass through the guide rail base 1 and the guide rail 3 in sequence, and the guide rail base 1 and the guide rail 3 are fixed and locked together by the nut 6. In addition, multiple fixing holes 4 are convenient for adjustment, which facilitates flexible adjustment of the width of the entire guide rail and is suitable for terminal blocks of different sizes and types.
[0028] Example 2
[0029] Combined with attachment Figure 2 , Attachment Figure 4 and attached Figure 5 , both sides of the guide rail base 1 are provided with fixed locking structures that cooperate with each other and are convenient for connection with adjacent guide rail bases 1, and the fixed locking structure includes a sleeve 7 arranged on one side of the guide rail base 1, and an insertion piece 8 used to cooperate with the sleeve 7 is provided on the other side of the guide rail base 1, and a limiting hole 13 is provided on both the sleeve 7 and the insertion piece 8.
