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.

[0017] Please see Figures 1-4In this embodiment of the utility model, a fuse with a safety protective cover includes a base 1, a front frame 5 fixedly connected to the front end of the base 1, a hinge 4 hinged to the outer wall of the front frame 5, an upper shell 2 fixedly connected to the top of the hinge 4, the base 1 and the upper shell 2 being connected in a closed-top manner, a pull handle 3 fixedly connected to the rear part of the upper surface of the upper shell 2, a blocking block 6 fixedly connected to the front end of the upper shell 2, the front frame 5 being installed at the front end of the base 1, the front frame 5 being used in conjunction with the upper hinge 4 to ensure the flip support of the upper shell 2, the upper shell 2 being connected to the upper hinge 4 through the top, and the upper hinge 4 being able to flip on the outer wall of the front frame 5; When the operator pulls the handle 3 upwards, the upper shell 2 uses the hinge 4 as a fulcrum to achieve a flipping action on the base 1, which is labor-saving and flexible. The top of the inner cavity of the upper shell 2 is fixedly connected to a baffle 8, and the bottom of the inner cavity of the base 1 is fixedly connected to a base 18. The upper surface of the base 18 is provided with a groove, and the upper surface of the groove is provided with a bolt mounting groove 14.

[0018] Please see Figures 2-3 Specifically: Triangular seats 12 are fixedly connected to the left and right sides of the upper surface of the base 18. Arc-shaped parts 13 are fixedly connected to the outer wall of the triangular seats 12. Arc-shaped parts 13 are installed on the side of the triangular seats 12 to squeeze the blade head 15 when it is inserted, ensuring a stable connection. It is elastic and adaptable to the insertion requirements of different sized blade heads, improving compatibility. Fixing plates 11 are fixedly connected to both ends of the base 18. Nut and bolt assembly 9 is installed on the upper surface of the fixing plates 11. A fuse 16 is placed in the upper part of the groove. Sealing plates 17 are fixedly connected to the front and rear ends of the fuse 16. A blade head 15 is fixedly connected to the center of the front surface of the sealing plate 17. Pulling the fuse 16 causes the blade heads 15 at both ends to be pulled out of the triangular seats 12, realizing the quick disengagement of the fuse without complicated disassembly. Bolts are installed in the inner cavity of the bolt mounting slot 14, with the bottom of the bolt penetrating the upper surface of the bolt mounting slot 14 and threadedly connected to the bottom of the inner cavity of the base 1. A baffle 8 is installed on one side of the base 18 to ensure that the fuse 16 will not cause the base 18 to detach during the insertion of the sealing plate 17, thus ensuring the stability of the device. The baffle 8 is fixed to the top of the inner cavity of the upper shell 2, and the baffle 8 is fixed to the fuse 16. When the upper shell 2 is flipped, the baffle 8 moves upward synchronously.

[0019] Please see Figure 3 Specifically: the bottom of the inner frame of the front frame 5 is fixedly connected to the base body 10, the upper surface of the base body 10 is provided with a fixing plate 11, the nut and bolt assembly 9 passes through the upper surface of the fixing plate 11 and is threadedly connected to the inner cavity of the base body 10.

[0020] The working principle of this utility model is as follows: In use, the front frame 5 installed at the front end of the base 1 is used to cooperate with the upper hinge 4, and the upper shell 2 connected to the top of the hinge 4 can be flipped on the base 1. When the person holds the handle 3 and lifts it up, the hinge 4 connected to the front end of the lower surface of the upper shell 2 will flip on the outer wall of the front frame 5 connected to the front end of the base 1, so that the upper shell 2 can be flipped on the base 1. The shielding block 6 connected to the front frame 5 is used to shield dust, and the observation port 7 installed on the upper shell 2 is used to pass through the circuit breaker, so as to facilitate real-time observation of the equipment status without disassembling the shell. The baffle 8 fixed at the top of the inner cavity of the upper shell 2 is pulled by the upper shell 2, causing the fuse 16 connected to the baffle 8 to detach from the base 18. Specifically: the fuse 16 and the baffle 8 are fixed, and the baffle 8 is connected to the top of the inner cavity of the upper shell 2. When the upper shell 2 is flipped upward, the baffle 8 will also flip upward with the upper shell 2, and the blades 15 connected to both ends of the fuse 16 connected to the upper shell 2 will be pulled out from the triangular seat 12. The arc-shaped part 13 installed on the side of the triangular base 12 is used to squeeze the cutter head 15 inserted into the inner frame of the triangular base 12. The triangular base 12 itself is elastic. The fixing plates 11 connected to both ends of the base 18, together with the nut and bolt assembly 9, can be threadedly connected to the inner cavity of the base body 10 at the bottom of the inner frame of the front frame 5, thereby fixing the fixing plates 11. The base 18 is threadedly fixed to the bottom of the inner cavity of the base 1 by the bolt in the bolt mounting groove 14, ensuring that the fuse 16 will not cause the base 18 to detach from the base 1 during the process of the sealing plate 17 being pulled in.
