[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Such as Figure 1 And Figure 2As shown in the figure, an embodiment of the present invention provides an anti-slip-off device for a fuse. The fuse includes a mounting base and a fuse tube. The rotating shaft of the fuse tube is rotatably arranged in the mounting base. The anti-slip-off device includes a frame body 10, a hook 20, and a buckle 30. The hook 20 is fixed at the end of the frame body 10 and is used to connect with the rotating shaft of the fuse tube. The buckle 30 is arranged on the frame body 10 and is located below the hook 20. The buckle 30 is used to abut against the bottom of the mounting base. The buckle 30 and the hook 20 cooperate to limit the rotating shaft of the fuse tube in the mounting base. Optionally, the opening of the hook 20 faces the buckle 30. The hook 20 hooks the rotating shaft of the fuse tube from above the mounting base, and the buckle 30 abuts against the bottom of the mounting base. The buckle 30 and the hook 20 cooperate to limit the rotating shaft in the mounting base.

[0022] In this technical solution, the hook 20 hooks the rotating shaft of the fuse tube, and the buckle 30 abuts against the bottom of the mounting base. In this way, the rotating shaft can be limited in the mounting base, and when the fuse tube is manually pushed, the fuse tube will not fall off the mounting base. In addition, this device also has the advantages of simple structure and convenient use.

[0023] In this embodiment, there are two hooks 20, and the two hooks 20 are arranged at intervals on both sides of the frame body 10. Optionally, the buckle 30 is located between the two hooks 20. Specifically, both ends of the rotating shaft of the fuse tube extend out of the mounting base, and the two hooks 20 respectively hook both ends of the rotating shaft of the fuse tube, and the buckle 30 abuts against the middle of the bottom of the mounting base, so that the rotating shaft can be stably limited in the mounting base.

[0024] Specifically, the buckle 30 is movably arranged on the frame body 10, and the distance between the buckle 30 and the hook 20 is adjustable. By adjusting the distance between the buckle 30 and the hook 20, the anti-slip-off device can be fixed on the mounting base or disassembled from the mounting base.

[0025] In this embodiment, the anti-slip-off device further includes a driving component 40. The driving component 40 is arranged on the frame body 10. The driving component 40 is drivingly connected to the buckle 30, and the driving component 40 is used to drive the buckle 30 to move relative to the frame body 10. The driving component 40 drives the buckle 30 to approach or move away from the hook 20.

[0026] Specifically, the driving assembly 40 includes a nut 41 and a push rod 42. The nut 41 is fixed on the frame body 10; the push rod 42 has a first end and a second end which are oppositely arranged. The push rod 42 is threadedly connected to the nut 41, and the first end 421 of the push rod abuts against the buckle 30. When the push rod 42 rotates along the nut 41, the push rod 42 drives the buckle 30 to approach or move away from the hook 20. The nut 41 and the push rod 42 can also position the buckle 30 so that the buckle 30 continuously abuts against the bottom of the mounting seat. In other embodiments, the driving assembly 40 can be a driving member such as a motor, a cylinder or a hydraulic cylinder. Of course, the buckle 30 can also be manually driven to approach or move away from the hook 20. The pitch of the threads on the nut 41 and the push rod 42 is relatively large, so that the push rod 42 can move quickly along the nut 41.

[0027] In this embodiment, a driving groove is provided on the end face of the second end 422 of the push rod. The driving groove is matched with the driving member to drive the push rod 42 to rotate. The driving member is provided with a driving protrusion, and the driving protrusion is stuck in the driving groove. The driving member rotates to drive the push rod 42 to rotate. Optionally, the driving member can be an insulating rod.

[0028] In this embodiment, a buckle limiting portion is provided on the frame body 10 to limit the stroke of the buckle 30. The buckle 30 moves along the buckle limiting portion, which can prevent the buckle 30 from skewing.

[0029] Specifically, the buckle limiting portion is a limiting groove 50 provided on the frame body 10, and the buckle 30 is slidably connected to the limiting groove 50. The buckle 30 approaches or moves away from the hook 20 along the limiting groove 50, preventing the buckle 30 from skewing, and the provision of the limiting groove 50 enables the buckle 30 to move smoothly.

[0030] In this embodiment, the frame body 10 includes two parallel support plates 11. The buckle 30 is arranged between the two support plates 11, and the limiting groove 50 is provided on the two support plates 11. That is, both ends of the buckle 30 are slidably connected in the two limiting grooves 50. The two hooks 20 can be respectively arranged at the tops of the two support plates 11. The hooks 20 are stuck at both ends of the rotating shaft, and at least part of the mounting seat is located between the two support plates 11. The buckle 30 abuts against the bottom of the mounting seat, thereby limiting the rotating shaft in the mounting seat.

[0031] Specifically, a card slot 31 is provided on one side of the buckle 30 close to the hook 20. The card slot 31 is used for clamping the bottom of the mounting seat. Optionally, the width of the card slot 31 is adapted to the width of the mounting seat. The card slot 31 is clamped at the bottom of the mounting seat to more stably limit the rotating shaft and prevent the rotating shaft from falling off the mounting seat.

[0032] In this technical solution, the card hook 20 hooks the rotating shaft of the fuse tube, and the buckle 30 abuts against the bottom of the mounting seat, so that the rotating shaft can be limited within the mounting seat. When the fuse tube is manually pushed, the fuse tube will not fall off the mounting seat. The driving component 40 adopts a nut and a push rod, which can not only drive the buckle 30 to approach or move away from the mounting seat, but also position the buckle 30 so that the buckle 30 continuously abuts against the mounting seat. There are two card hooks 20, which respectively hook the two ends of the rotating shaft, and the buckle 30 abuts against the bottom of the mounting seat, so that the connection between the rotating shaft and the mounting seat is more stable and the rotating shaft is prevented from falling off the mounting seat. This device also has the advantages of simple structure and convenient use.
