[0024] 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.

[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides an environmentally friendly gas-insulated fully enclosed circuit breaker cabinet, including a base 1 and a cabinet 2 located on top of the base 1. A shell 3 is fitted around the rear end of the cabinet 2, and multiple spaced rollers 11 are installed at the bottom of both ends of the shell 3. A connector for connecting the base 1 is provided on the rear end of the shell 3. The connector includes a fixing plate 4 installed on the rear side of the shell 3. A T-shaped connecting plate 5 is provided at the bottom of the fixing plate 4. Two telescopic rods 6 for connecting the fixing plate 4 are installed on the top of the connecting plate 5, and springs 7 are fitted around the bottom of the telescopic rods 6. A connecting seat 8 for connecting the base 1 is provided at the bottom of the connecting plate 5, and a connecting groove 9 is opened on the top of the connecting seat 8. The bottom end of the connecting plate 5 extends into the connecting groove 9.

[0026] To ensure the stability of the cabinet 2, the shell 3 needs to be assembled on the outside of the cabinet 2. Since the bottom of both ends of the shell 3 is equipped with rollers 11, the staff can push the shell 3 supported by the rollers 11 to move. Since the rear end of the base 1 has two spaced guide holes 10, the multiple rollers 11 located at the bottom of both ends of the shell 3 are respectively located inside the two guide holes 10. This allows the rollers 11 at the bottom of both ends of the shell 3 to move into the two guide holes 10 respectively. This provides space to fit the shell 3 on the outside of the cabinet 2, ensuring that the shell 3 can provide multi-faceted protection for the cabinet 2 and prevent damage to the cabinet 2 from external impacts.

[0027] After the housing 3 is fitted onto the outside of the cabinet 2, a connecting piece is needed to limit the housing 3 to ensure its stability. To improve the convenience of operating the connecting piece, a handle 12 is provided on the top of the fixing plate 4. A connecting post 13 is installed at the bottom of the handle 12. The bottom of the connecting post 13 passes through the fixing plate 4 and is fixed to the top of the connecting plate 5. In this way, before assembling the housing 3, the handle 12 can be lifted, and the connecting post 13 on the handle 12 can be used to move the connecting plate 5 upward, so that the connecting plate 5 is above the connecting seat 8. After the housing 3 is assembled into the cabinet 2, the handle 12 can be released, and then the spring force of the spring 7 can be used to move the connecting plate 5 downward, so that the connecting plate 5 is inserted into the connecting groove 9. The engagement of the connecting plate 5 and the connecting groove 9 limits the housing 3 and ensures the stability of the housing 3.

[0028] To prevent prolonged lifting of the handle 12, a limiting mechanism is needed. Therefore, a retaining ring 14, connected via a bearing, is fitted around the top of the handle 12. The top of the retaining ring 14 has a hook 15, the front end of which is fixed to the rear side of the housing 3. This allows the handle 12 to be stopped after lifting by rotating the retaining ring 14 and hook 15, thus limiting the handle 12 after lifting.

[0029] To prevent the housing 3 from wobbling vertically, two spaced positioning slots 19 are provided on the rear side of the base 1. Each positioning slot 19 contains an L-shaped positioning bracket 20, with the front end of the positioning bracket 20 away from the positioning slot 19 fixed to the rear side of the housing 3. This allows the positioning bracket 20 to engage with the positioning slot 19 simultaneously after the housing 3 has moved outside the cabinet 2. The engagement of the positioning bracket 20 with the positioning slot 19 limits the position of the housing 3, preventing vertical displacement and ensuring its stability.

[0030] After the housing 3 is assembled, the cabinet 2 can be protected from multiple angles by the protective components on the housing 3. The housing 3 has multiple sets of protective components for impact protection. Each set of protective components includes multiple screws 16 installed on the outside of the housing 3. A common buffer plate 17 is fitted over the screws 16. Multiple return springs 21 are located on the side of the buffer plate 17 closest to the housing 3, and each return spring 21 is fitted over the screws 16. A threaded ring 18 is threaded onto the end of each screw 16 away from the housing 3. The threaded ring 18 is located on the side of the buffer plate 17 away from the housing 3. This allows the buffer plate 17 to be the first to contact the impact, preventing the impact from directly acting on the housing 3, thus ensuring the integrity and protection of the housing 3. Simultaneously, the elasticity of the return springs 21 allows them to absorb and cushion the impact on the buffer plate 17, preventing excessive impact from damaging the buffer plate 17 and the housing 3. This ensures the protective performance of the buffer plate 17 and the housing 3 for the cabinet 2.

[0031] After rotating the screw ring 18, the buffer plate 17 and the return spring 21 can be disassembled, which facilitates the disassembly and replacement of the return spring 21 and the buffer plate 17, ensuring the performance of the return spring 21 and the buffer plate 17.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
