[0002] The cabinet of the GGD type AC low-voltage switchgear adopts the form of a general cabinet. The frame is assembled by partial welding of 8MF cold-formed steel. The frame parts and special accessories are supplied by the designated steel manufacturers.

[0003] 8MF cold-formed steel profiles are equipped with Φ9 mounting holes with a 20mm module. They have a high versatility and are formed by one-time roll forming of hot-rolled steel strips. However, they are prone to heavy oil stains, and the pickling, phosphating, and degreasing processes are no longer suitable for current environmental protection requirements. Currently, GGD type AC low-voltage distribution cabinets widely use aluminum-zinc coated steel sheets rolled into "C" profiles with Φ5.2 mounting holes with a 20mm module. As a result, the installation accessories for the ZMJ type combined insulated busbar frame, which is designed as an 8MF profile, are not suitable for the installation of "C" profiles.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-4 Shown:

[0033] Example 1:

[0034] An insulated busbar frame mounting structure for a distribution cabinet, mounted on an insulated busbar frame 1, includes:

[0035] 2 uprights;

[0036] Horizontal beam 3 is installed on top of vertical pole 2;

[0037] The second attachment 5 is set on one side of the insulated busbar frame 1, and a process hole 301 is opened on one side of the crossbeam 3;

[0038] The fixing component 6 includes a bolt 601 located at the connection between the second accessory 5 and the crossbeam 3, and a nut 602 is threaded onto the middle of the bolt 601.

[0039] The limiting component 7 is located at the bottom of the bolt 601 and is used to limit the movement of the bolt 601.

[0040] It should be noted that the process hole 301 opened on the crossbeam 3 and the second accessory 5 are used to fix the position of the insulating busbar frame 1.

[0041] Specifically, a first accessory 4 is provided on the other side of the insulated busbar frame 1, and a self-tapping screw 8 is provided at the connection between the first accessory 4 and the upright 2. The self-tapping screw 8 is used to fix the position of the first accessory 4.

[0042] It should be noted that the insulated busbar frame 1, the first accessory 4, and the second accessory 5 are connected by through bolts. When it is necessary to connect the first accessory 4 to the upright 2, the first accessory 4 is first moved to the required position, and then the first accessory 4 and the upright 2 are fixed together by self-tapping screws 8.

[0043] Specifically, the horizontal longitudinal section of the second annex 5 is set to L-shape, and the second annex 5 is used to connect the crossbeam 3 and the insulating busbar frame 1.

[0044] It should be noted that the L-shaped second attachment 5 is used to connect the vertically placed crossbeam 3 and the insulating busbar frame 1. A through hole is provided at the bottom of the second attachment 5 so that the bolt 601 can pass through the second attachment 5 through the through hole.

[0045] Example 2:

[0046] Restriction component 7 is applied to the installation structure in Embodiment 1;

[0047] Specifically, limiting component 7 includes:

[0048] The fixing block 706 is inserted into the interior of the process hole 301;

[0049] Hexagonal slot 701 is formed at the top of the fixing block 706, and bolt 601 is inserted and connected inside the hexagonal slot 701;

[0050] A movable component is located on one side of the spring 707 and is used to move the position of the spring 707.

[0051] It should be noted that the movable component is used to move the position of the fixed block 706. A hexagonal groove 701 that matches the screw head of the bolt 601 is provided at the top of the fixed block 706. When it is necessary to fix the position of the second accessory 5, the bolt 601 is first inserted into the process hole 301, and then the fixed block 706 is moved upward by the movable component. The hexagonal groove 701 restricts the rotation of the bolt 601, so as to avoid the situation where the other hand is needed to fix the position of the bolt 601 when tightening the nut 602.

[0052] Specifically, the moving parts include:

[0053] The through-hole block 705 is fixedly connected to one side of the fixed block 706;

[0054] Sliding block 703, therefore sliding block 703 is fixedly connected to one side of the through block 705;

[0055] Connecting rod 708 is fixedly connected to the bottom end of sliding block 703;

[0056] Pull block 709 is fixedly connected to the bottom end of connecting rod 708.

[0057] Specifically, the moving part also includes a spring 707 disposed at the bottom of the sliding block 703. The spring 707 is used to push the sliding block 703. A fixing frame 702 is inserted and connected inside the process hole 301. A cavity 704 is opened in the middle of the fixing frame 702. The sliding block 703 and the spring 707 are both inserted and connected inside the cavity 704. The connecting rod 708 is inserted and connected to the inner wall at the bottom of the cavity 704. A through hole is opened on one side of the cavity 704. A through block 705 is inserted and connected inside the through hole.

[0058] It should be noted that the cavity 704 is adapted to the sliding block 703, allowing the sliding block 703 to slide inside the cavity 704. The through block 705 is adapted to the through hole, and the through block 705 is used to connect the sliding block 703 located inside the cavity 704 and the fixed block 706 located outside the cavity 704.

[0059] Furthermore, when fixing the position of bolt 601, first move connecting rod 708 and sliding block 703 towards one side of spring 707 by pulling block 709. Spring 707 is compressed and deformed. After moving bolt 601 to the desired position, release the pull on pulling block 709. The force of spring 707 restoring its deformation will drive sliding block 703 to reset.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
