[0036] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] Example 1

[0038] Figure 1 This is a schematic diagram of the guide rail latch in this utility model. Figure 1 As shown, the guide rail buckle 1 includes a fixed base 11, a sliding buckle 12 and a spring 13. The fixed base 11 and the sliding buckle 12 are fitted together, and a receiving space is formed between the fixed base 11 and the sliding buckle 12. The spring 13 is installed in the receiving space.

[0039] like Figure 2 As shown, the fixed base 11 includes a first back plate 111, a first side plate 112, a second side plate 113, a first latch 114, a first baffle 115, and a first limiting opening 116. The first side plate 112 is connected to both sides of one end of the first back plate 111, and the second side plate 113 is connected to both sides of the other end of the first back plate 111. The first latch 114 is provided at the end of the first side plate 112 away from the second side plate 113, and the first baffle 115 is provided at the end of the second side plate 113 away from the first side plate 112. The first limiting opening 116 is formed between the first baffle 115 and the first back plate 111.

[0040] The first back plate 111 may be a T-shaped plate, so that there is a positional difference between the first side plate 112 and the second side plate 113 along the width direction of the first back plate 111, so as to install the sliding buckle 12.

[0041] The first back plate 111 has a first threaded hole 1111, and a screw for connecting the fixed base 11 and the electrical equipment housing 2 is installed in the first threaded hole 1111; and a slot 1112 is provided at the end of the first back plate 111 away from the first side plate 112.

[0042] The first limiting port 116 provides operable space for inserting the spring 13, which makes the assembly of the spring 13 simpler and easier.

[0043] A first baffle 115 is installed between the two second side plates 113. The first baffle 115 is used to mount the spring 13 and provides a support surface for the spring 13 when it abuts against the sliding buckle 12. The first baffle 115 is prepared by repeatedly bending a portion cut from the body of the fixed base 11. The first baffle 115 includes a locking block 1151, which is used to limit the sliding buckle 12 in a direction perpendicular to the first back plate 111.

[0044] like Figure 3 As shown, the sliding buckle 12 includes a second back plate 121, a third back plate 122, a third side plate 123, a second latch 124, a second baffle 125, and a mounting hole 126. The second back plate 121 and the third back plate 122 are connected by the third side plate 123. The third side plate 123 is disposed on both sides of the second back plate 121 and the third back plate 122. The second back plate 121 and the third back plate 122 are installed along the length direction of the third side plate 123. There is a gap between the second back plate 121 and the third back plate 122. The end of the third side plate 123 near the second back plate 121 is provided with the second latch 124. The end of the third back plate 122 near the second back plate 121 is provided with the second baffle 125. The mounting hole 126 is provided on the third back plate 122.

[0045] The mounting hole 126 includes an inlet hole 1261, a through hole 1262, and a reserved hole 1263. The through hole 1262 connects the inlet hole 1261 and the reserved hole 1263. The inlet hole 1261 is located on the third back plate 122 near the second back plate 121, and the reserved hole 1263 is located on the third back plate 122 away from the second back plate 121. The size of the inlet hole 1261 is larger than the size of the locking block 1151, and the size of the through hole 1262 is smaller than the size of the locking block 1151. The reserved hole 1263 is used to remove the sliding buckle 12 from the fixed base 11.

[0046] The second bayonet 124 is disposed opposite to the first bayonet 114 to accommodate the side of the guide rail.

[0047] Furthermore, combined Figure 2 and Figure 3The guide rail buckle 1 also includes a limiting component. In this embodiment, the limiting component is the limiting plate 127, which is disposed at the end of the second back plate 121 away from the third back plate 122. The limiting plate 127 is prepared by repeatedly bending a portion cut from the body of the guide rail buckle 1. A protrusion 1271 extends from the end of the limiting plate 127 in a direction parallel to the first back plate 111. The protrusion 1271 is used to limit the sliding buckle 12 in a direction perpendicular to the first back plate 111 and to ensure that the sliding buckle 12 slides on the fixed base 11 and does not disengage within a certain sliding distance range.

[0048] Correspondingly, a second limiting opening 117 is provided on the first back plate 111, and the second limiting opening 117 is used to accommodate the limiting plate 127.

[0049] Combination Figures 1 to 3 When the sliding buckle 12 and the fixed base 11 are installed together, the first baffle 115 is inserted into the guide hole 1261 and moves from the guide hole 1261 into the through hole 1262 to limit the sliding buckle 12 along the vertical direction of the first back plate 111. After installation, the inner wall of the third side plate 123 and the outer wall of the second side plate 113 are in direct contact, and an installation space for installing the guide rail is formed between the first latch 114 and the second latch 124. The second baffle 125 is installed in the first limiting port 116, and the end of the second baffle 125 is engaged with the slot 1112, so that the sliding buckle can slide along the length direction of the first back plate 111 within a certain sliding distance range without detaching from the fixed base 11; and the first baffle 115, the second baffle 125, the third back plate 122 and the second side plate 113 together form a receiving space for installing the spring 13. The limiting plate 127 passes through the second limiting opening 117, and the protrusion 1271 directly contacts the back of the first back plate 111. The spring 13 is inserted from the first limiting opening 116 between the first baffle 115 and the second baffle 125, thus completing the installation of the guide rail buckle 1. After installation, the fixed base 11 and the sliding buckle 12 abut against each other, ensuring that the subsequent guide rail can be effectively locked; and limiting the sliding buckle 12 within its sliding stroke, preventing improper operation by the worker from causing the sliding buckle 12 to detach from the guide rail and the fixed base 11.

[0050] like Figure 4 As shown, this utility model also provides an electrical device, which includes a guide rail 3, a housing 2 and a guide rail buckle 1 as described above. The guide rail 3 is mounted on the guide rail buckle 1, and the guide rail buckle 1 is mounted on the housing 2.

[0051] like Figure 5 and Figure 6 As shown, the housing 2 has a first notch 21 and a second notch 22. The end of the first baffle 115 is installed in the first notch 21, and the limiting plate 127 is installed in the second notch 22. The housing 2 also has a second threaded hole 23, which corresponds to the position of the first threaded hole 1111. Screws for connecting the fixed base 11 and the electrical equipment housing 2 are also installed in the second threaded hole 23.

[0052] The guide rail 3 is U-shaped, and the side of the guide rail 3 is engaged with the first bayonet 114 and the second bayonet 124 for fixation.

[0053] During the installation of the electrical equipment, screws are inserted into the first threaded hole 1111 through the upper ends of the first limiting port 116 and the sliding buckle 12, and the assembled guide rail buckle 1 is fixed to the housing 2 with screws. The housing 2 blocks the first limiting port 116, ensuring the concealed installation of the spring 13 and preventing slippage. Further, the guide rail 3 is snapped between the first latch 114 and the second latch 124.

[0054] Example 2

[0055] This utility model also provides another installation method for the fixed base 11 and the sliding buckle 12. In this embodiment, the difference from Embodiment 1 is that: combined with Figures 6 to 8 As shown, the sliding buckle 12 does not have the limiting plate 127, and the first back plate 111 of the fixed base 11 does not have the second limiting port 117. Correspondingly, the housing 2 does not have the second notch 22.

[0056] In this embodiment, the limiting components are a third latch 1131 and a fourth latch 1132. The third latch 1131 and the fourth latch 1132 are disposed on the second side plate 113 of the fixed base 11. The third latch 1131 is located on the second side plate 113 near the first side plate 112, and the fourth latch 1132 is spaced apart from the third latch 1131. When the sliding buckle 12 and the fixed base 11 are installed together, the third latch 1131 engages with the upper end of the second back plate 121, and the fourth latch 1132 engages with the upper end of the third back plate 122. The third latch 1131 and the fourth latch 1132 limit the sliding buckle 12 along the vertical and length directions of the first back plate 111.

[0057] Furthermore, the inlet hole 1261 and the through hole 1262 in this embodiment have the same shape.

[0058] In summary, this utility model provides a guide rail buckle and electrical equipment. By providing a second baffle 125 on the sliding buckle 12 and a first baffle 115 on the fixed base 11, a space for accommodating the spring 13 is formed between the first baffle 115, the second baffle 125, the third back plate 122, and the side plates on both sides. The first limiting port 116 provides operating space for the installation of the spring 13. The guide rail buckle 1 features a concealed spring 13 design, effectively solving the problem of spring 13 loosening and slippage, improving the convenience of pre-assembly, and optimizing installation efficiency and reliability.
