Technical Field

[0001] This utility model discloses a stable sheet metal part, belonging to the field of power facilities. Background Technology

[0002] Electrical copper busbars are long conductors with rectangular or rounded cross-sections made of copper. They are high-current conductive products, and their core applications include electrical engineering projects such as high and low voltage electrical appliances, power distribution equipment, and busbar trunking.

[0003] During the installation of copper busbars, related sheet metal accessories are required. For example, when installing copper busbars in a distribution cabinet, the spacing between them in series needs to be greater than the thickness of a single copper busbar. The spacing between them in series also needs to meet the corresponding heat dissipation requirements. Some existing sheet metal parts for installing copper busbars support adjustable spacing. However, the adjustment method of these sheet metal parts is often just a simple sliding overlap, which has poor stability.

[0004] In response to the above problems, a new improvement plan is proposed. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] like Figure 1 As shown, a sturdy sheet metal part includes: Frame 1, installed in the distribution cabinet, includes several columns 11 and beams 12 that are spliced ​​and fixed to each other; Fixing base 2 is used to install copper busbars, and fixing base 2 is fixedly connected to crossbeam 12; The movable seat 3 is used to install copper busbars. There are two movable seats 3, and both movable seats 3 are slidably connected to the crossbeam 12. By setting one fixed seat 2 and two movable seats 3, it can be adapted to the three-phase busbars commonly found on the market, and can be distinguished by yellow, green and red colors. Clamping component 4 is used to make the copper busbar tightly adhere to the fixed seat 2 or the movable seat 3; Adjustment component 5 is used to adjust the position of the movable seat 3 on the crossbeam 12; The adjusting assembly 5 includes two sets of transmission rods 51 and an adjusting handle 52. The adjusting handle 52 is fixedly connected to one end of the transmission rod 51. The transmission rod 51 passes through all the movable seats 3 and the fixed seat 2 and is rotatably connected to the column 11. One transmission rod 51 forms a screw drive with one of the movable seats 3, and the other transmission rod 51 forms a screw drive with another movable seat 3. Screw drive, also known as helical drive, is a mechanical device that precisely converts rotary motion into linear motion or torque into thrust. The simplest existing screw drive system generally consists of two parts: a threaded shaft, equivalent to the transmission rod 51 of this product, and a nut with an internal thread that matches the shaft, equivalent to the movable seat 3 of this product. Since one transmission rod 51 only has a screw drive with one corresponding movable seat 3, That is, one transmission rod 51 is threadedly connected to only one corresponding movable seat 3. The other movable seat 3, through which the transmission rod 51 passes, is not threaded. Therefore, when one transmission rod 51 rotates, one of the movable seats 3 connected to it by a screw drive will move linearly on the crossbeam 12. The part of the rotating transmission rod 51 that passes through the other movable seat 3 is idle and will not drive the other movable seat 3 to move. Therefore, it can achieve the effect of adjusting a single movable seat 3. By rotating the adjusting handle 52, the transmission rod 51 is rotated, thereby changing the position of the movable seat 3 on the crossbeam 12. After adjustment, by utilizing the characteristics of screw drive, if there is no external force to rotate the transmission rod 51, it can achieve an automatic locking effect, ensuring that the movable seat 3 will not slip and making the whole system stable.

[0019] like Figure 1 , Figure 2 As shown, both the fixed base 2 and the movable base 3 include an integrally formed mounting part 6 and a snap-fit ​​part 7. The snap-fit ​​parts 7 are symmetrically arranged on both sides of the mounting part 6. The mounting part 6 has mounting holes 61, and the snap-fit ​​parts 7 have slots 71. When using this product, the copper busbar is slidably inserted into the slot 71 of the snap-fit ​​part 7 from the side, and the hole on the copper busbar is aligned with the mounting hole 61 on the mounting part 6. Then, bolts are used to connect and fix it. At this time, the copper busbar is fixed on the mounting part 6, and both ends are inserted into the slots 71 of the snap-fit ​​part 7 for subsequent wiring.

[0020] like Figure 3As shown, the clamping assembly 4 includes an adjusting bolt 41 and a washer 42. The adjusting bolt 41 is threadedly connected to the locking part 7, and the washer 42 is fixedly connected to the adjusting bolt 41. When both ends of the copper busbar are inserted into the slot 71, the clamping assembly 4 can be used to make it fit tightly against the locking part 7. Specifically, the adjusting bolt 41 is rotated, causing the adjusting bolt 41 to drive the washer 42 to move closer to the copper busbar, thereby forming abutment against it. Furthermore, the washer 42 includes a connecting part 421 and an insulating part 422. The connecting part 421 is fixedly connected to the adjusting bolt 41, and the insulating part 422 wraps around the connecting part 421 and is fixedly connected to it. The connecting part 421 is made of metal to ensure that it can be welded and fixed to the adjusting bolt 41. The insulating part 422 is made of insulating rubber so that it will not affect the circuit when pressing the copper busbar. In addition, several levers 43 are fixedly connected to the adjusting bolt 41. By setting the levers 43, the adjusting bolt 41 can be rotated by applying force with the levers 43, making it easier to rotate the adjusting bolt 41.

[0021] like Figure 1 As shown, multiple adjustment handles 52 are arrayed along the axis of the transmission rod 51. Similarly, when rotating the transmission rod 51 to adjust the position of the movable seat 3, multiple adjustment handles 52 can be used to assist, making it more labor-saving.

[0022] like Figure 4 As shown, a groove 121 is provided on the crossbeam 12, and several rotating rods 122 are rotatably arranged in the groove 121. The rotating rods 122 have a portion extending out of the groove 121 and abutting against the movable seat 3. By setting multiple rotatable rotating rods 122, the friction between the movable seat 3 and the crossbeam 12 during the movement is reduced, making the adjustment process smoother.
