[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore are not to be construed as limiting the present invention. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0022] like Figure 1-3 It is a structural schematic diagram of a busbar in a preferred embodiment of the utility model. In this embodiment, a busbar includes a connecting seat 1 and a fixed seat 2. The connecting seat 1 is plugged and connected in the fixed seat 2. A connecting groove 3 is opened in the fixed seat 2. A plurality of isolation plates 4 are fixedly connected in the connecting groove 3, and a connecting cavity 5 is formed by two isolation plates 4. Multiple groups of connecting seats 1 can be plugged and connected through the multiple connecting cavities 5, and the position relationship of the connecting pieces 9 between the multiple groups of connecting seats 1 is in a staggered design. Sliding bars 6 are symmetrically fixedly connected to the inner wall of the connecting cavity 5, and a card groove 12 is opened on the inner wall of the connecting cavity 5 below the sliding bar 6 on one side, a sliding groove 8 is opened on the outer wall of the connecting seat 1 at a position relative to the sliding bar 6, and an elastic card block 11 is fixedly connected to the outer wall of the connecting seat 1 at a position relative to the card groove 12. This structural design realizes the fixing effect between the connecting seat 1 and the fixed seat 2, and effectively solves the problems raised in the background technology.

[0023] In this embodiment, the sliding bar 6 is slidably connected in the sliding groove 8, so that the connection between the connecting seat 1 and the fixed seat 2 is achieved through an opening on one side of the fixed seat 2, the sliding groove 8 is aligned with the sliding bar 6, and one of the connecting seat 1 or the fixed seat 2 is pushed, and the sliding bar 6 slides into the sliding groove 8. At the same time, during the sliding process, the elastic card block 11 is clamped in the card slot 12 to achieve fixation.

[0024] In this embodiment, a plurality of connecting pieces 9 are fixedly connected to one side of the connecting seat 1. By opening a socket 10 on the surface of the connecting piece 9, the connecting piece 9 and the connected member can be quickly connected.

[0025] In this embodiment, a notch 7 is provided on the outer wall surface of the connecting seat 1 between the two connecting pieces 9, and an upwardly tilted elastic block 11 is fixedly connected in the notch 7. Due to this structural design, when the sliding bar 6 slides into the sliding groove 8 for sliding connection, the elastic block 11 will be restricted, resulting in the inability to slide. Therefore, through this structural design, the sliding bar 6 slides into the sliding groove 8 for sliding connection, and the elastic block 11 is subjected to the pressure of the inner wall of the connecting cavity 5 and bends toward the notch, so that the sliding bar 6 can slide into the sliding groove 8 and be smoothly slidably connected.

[0026] In this embodiment, the elastic block 11 is designed to be at an angle of 25° with the surface of the connecting seat 1. With this structural design, the elastic block 11 is inserted into the slot 12, which is convenient for subsequent disassembly and assembly.

[0027] In this embodiment, notches 13 are provided on both sides of the outer wall of the connection seat 1 at positions opposite to the notch, and the length of the connection seat 1 can be easily cut according to the actual required length through the notches 13 .

[0028] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
