DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Reference Figure 1-2 As shown, a busbar trunking for power transmission and distribution provided by the present utility model includes: a busbar trunking body 1 provided with conductive bars 5 at both ends, and protective members for protecting the conductive bars 5 are provided at both ends of the busbar trunking body 1. The protective members include a protective sleeve 4 and an adjusting bolt 3. The adjusting bolt 3 is used to limit the protective sleeve 4 at the end of the busbar trunking body 1, and the protective sleeve 4 covers the conductive bar 5.

[0024] Combined Figure 4-5 As shown, cover plates 13 are detachably installed at the opposite ends of the two protective sleeves 4, and the cover plates 13 are used to block the ends of the protective sleeves 4.

[0025] As described above, when using the conductive bar 5, the busbar trunking body 1 and the protective members provided by the present utility model, the protective sleeve 4 in the protective members is detachably installed at the end of the busbar trunking body 1 through the adjusting bolt 3, so as to protect the conductive bar 5 through the protective sleeve 4, and protect the end of the protective sleeve 4 through the cover plate 13, avoiding external dust from falling on the conductive bar 5, and at the same time avoiding the conductive bar 5 from being bumped through the end of the protective sleeve 4.

[0026] Furthermore, in order to facilitate the detachable installation of the cover plate 13 on the protective sleeve 4, reference Figure 5 As shown, a circumferential clamping block 15 is provided on the inner wall of the cover plate 13, and an annular groove 14 for clamping the clamping block 15 is provided on the outer wall of the end of the protective sleeve 4. The cover plate 13 is detachably installed on the protective sleeve 4 through the clamping block 15 and the annular groove 14. When the conductive bar 5 needs to be connected, the cover plate 13 is separated from the protective sleeve 4 to facilitate exposing the conductive bar 5.

[0027] In the present utility model, combined Figure 2 As shown, a reset mechanism for automatically resetting the protective sleeve 4 to the outside of the conductive bar 5 is further provided at the end of the busbar trunking body 1 of this embodiment. The reset mechanism includes a moving seat 9 and a spring 10. A moving groove 2 is axially provided on the outer wall of the busbar trunking body 1, and the moving seat 9 and the spring 10 are sequentially installed in the moving groove 2. The adjusting bolt 3 is arranged between the protective sleeve 4 and the moving seat 9.

[0028] Combined Figure 2 As shown, a through hole 8 penetrates through the outside of the end of the protective sleeve 4 close to the busbar trunking body 1, a threaded hole 7 coaxial with the through hole 8 penetrates through the moving seat 9, and one end of the adjusting bolt 3 passes through the through hole 8 and is screwed into the threaded hole 7.

[0029] As described above, when using the reset mechanism provided by the present utility model, when the protective sleeve 4 is sleeved on the busbar body 1 and moves towards the side away from the conductive bar 5, the spring 10 is compressed by the moving seat 9. At this time, it is convenient to connect the conductive bar 5. When the protective sleeve 4 is released, the spring 10 releases, thereby automatically driving the moving seat 9 to move in the moving groove 2, and further automatically driving the protective sleeve 4 to cover the outside of the conductive bar 5.

[0030] Furthermore, in order to facilitate the connection of the adjusting bolt 3 between the protective sleeve 4 and the moving seat 9, referring to Figure 2 as shown, a positioning hole 6 coaxial with the threaded hole 7 is formed in the inner wall of the moving groove 2 near one end of the protective sleeve 4, and one end of the adjusting bolt 3 can be inserted into the positioning hole 6. The through hole 8 facilitates the adjusting bolt 3 to pass through the protective sleeve 4 and enter the threaded hole 7 on the moving seat 9. When the adjusting bolt 3 enters the positioning hole 6, it prevents the protective sleeve 4 from detaching from covering the outside of the conductive bar 5.

[0031] Furthermore, in order to facilitate the guiding of the spring 10, referring to Figure 2 and Figure 6 as shown, a guiding rod 11 for guiding the spring 10 is further provided on the moving seat 9, and a guiding hole 12 for accommodating the telescopic movement of the guiding rod 11 is formed at the end of the moving groove 2. The guiding rod 11 axially guides the spring 10, and at the same time, the guiding hole 12 prevents the guiding rod 11 from interfering with the movement of the moving seat 9.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
