[0022] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-Figure 5 The utility model provides a technical solution: a protective structure for a bus duct, the protective structure for a bus duct comprising: a bus duct 1, a joint 2 is provided on the end face of the bus duct 1, and a positioning groove 3 is opened on the surface of the bus duct 1;

[0024] A protective plate 4 is provided with a bottom plate 5 on the side of the protective plate 4, a vertical rod 6 is provided on the surface of the bottom plate 5, a limit spring 7 and a support plate 8 are sleeved on the surface of the vertical rod 6, and a limit rod 9 is provided at the bottom of the support plate 8;

[0025] During use, when it is necessary to protect the joint 2 of the bus duct 1, first move the support plate 8, then the protective plate 4 can be attached to the side of the joint 2, and the limiting rod 9 set at the bottom of the support plate 8 is inserted into the positioning groove 3, so that one group of protective plates 4 can be fixed, and the other group of protective plates 4 is fixed to the other side of the joint 2 in the same way, so that the joint 2 can be protected by two groups of protective plates 4. When the joint 2 needs to be used, the limiting rod 9 can be directly pulled out from the positioning groove 3 to remove the protective plate 4, which is more convenient and simple.

[0026] Example 2: On the basis of Example 1, in order to facilitate the protection of the connector 2 at one end of the bus duct 1, a protective plate 4 is provided, the bottom plate 5 is fixedly connected to the side of the protective plate 4, two groups of vertical poles 6 are provided, and the two groups of vertical poles 6 are symmetrically distributed about the bottom plate 5. A baffle 16 is provided on the surface of the vertical pole 6, and the support plate 8 is a "Z"-shaped plate structure as a whole.
