Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, an embodiment of the present invention provides an anti-slip device for a fuse, where the fuse includes a mounting seat and a fuse tube, a rotating shaft of the fuse tube is rotatably disposed in the mounting seat, and the anti-slip 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 the hook 20 is used for connecting with the rotating shaft of the fuse tube; the buckle 30 is arranged on the frame body 10 and located below the hook 20, the buckle 30 is used for abutting against the bottom of the mounting seat, and the buckle 30 and the hook 20 are matched with each other to limit the rotating shaft of the fuse tube in the mounting seat. Optionally, the opening of the hook 20 faces the catch 30. The trip 20 catches on the pivot of fusing tube from the top of mount pad, and buckle 30 makes the pivot spacing in the mount pad with the cooperation of trip 20 with the bottom butt of mount pad, buckle 30.

In this technical scheme, with the pivot of trip 20 catching on the fuse tube, buckle 30 and the bottom butt of mount pad are so can be spacing in the mount pad with the pivot, when artifical promotion fuse tube, the fuse tube can not drop from the mount pad. In addition, the device also has the advantages of simple structure and convenient use.

In this embodiment, there are two hooks 20, and the two hooks 20 are spaced apart from each other on two sides of the frame 10. Optionally, the catch 30 is located between two catches 20. Specifically, the two ends of the rotating shaft of the fuse tube extend out of the mounting seat, the two hooks 20 hook the two ends of the rotating shaft of the fuse tube respectively, and the buckle 30 abuts against the middle part of the bottom of the mounting seat, so that the rotating shaft can be stably limited in the mounting seat.

Specifically, the clip 30 is movably disposed on the frame body 10, and a distance between the clip 30 and the hook 20 is adjustable. The distance between the buckle 30 and the hook 20 is adjusted to fix the anti-slip device on the mounting seat or detach the anti-slip device from the mounting seat.

In this embodiment, the anti-slip device further includes a driving assembly 40, the driving assembly 40 is disposed on the frame body 10, the driving assembly 40 is in driving connection with the buckle 30, and the driving assembly 40 is used for driving the buckle 30 to move relative to the frame body 10. The driving assembly 40 drives the catch 30 toward or away from the hook 20.

Specifically, the drive 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 in threaded connection with the nut 41, and the first end 421 of the push rod is abutted 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 separate from the hook 20. Nut 41 and push rod 42 may also position clip 30 such that clip 30 is continuously abutting the mount base. In other embodiments, the driving assembly 40 may be a driving member such as an electric motor, an air cylinder, or a hydraulic cylinder. Of course, the catch 30 can also be manually driven closer to or further away from the hook 20. The pitch of the threads on the nut 41 and the push rod 42 is large to allow the push rod 42 to move quickly along the nut 41.

In this embodiment, the end surface of the second end 422 of the push rod is provided with a driving groove, and the driving groove is matched with the driving member to drive the push rod 42 to rotate. The driving part is provided with a driving protrusion which is clamped in the driving groove, and the driving part rotates to drive the push rod 42 to rotate. Alternatively, the drive member may be an insulated rod.

In this embodiment, the frame body 10 is provided with a buckle limiting portion for limiting the stroke of the buckle 30. The clip 30 moves along the clip stopper, so that the clip 30 can be prevented from being inclined.

Specifically, the buckle limiting part is a limiting groove 50 arranged on the frame body 10, and the buckle 30 is slidably connected with the limiting groove 50. The clip 30 is close to or far from the hook 20 along the limiting groove 50 to prevent the clip 30 from being inclined, and the limiting groove 50 is provided to enable the clip 30 to move smoothly.

In this embodiment, the frame body 10 includes two support plates 11 disposed in parallel, the clip 30 is disposed between the two support plates 11, and the limiting groove 50 is disposed on the two support plates 11. That is, the two ends of the clip 30 are slidably connected in the two limiting grooves 50. Two hooks 20 may be respectively disposed at the top ends of the two support plates 11. The trip 20 card is at the both ends of pivot, and the mount pad is located between two backup pads 11 at least partially, and buckle 30 butt is in the mount pad bottom to it is spacing in the mount pad with the pivot.

Specifically, a clamping groove 31 is formed on one side of the buckle 30 close to the hook 20, and the clamping groove 31 is used for clamping the bottom of the mounting seat. Optionally, the width of draw-in groove 31 and the width looks adaptation of mount pad, draw-in groove 31 card are in the bottom of mount pad to spacing pivot more firmly prevents that the pivot from droing from the mount pad.

In the technical scheme, the hook 20 hooks the rotating shaft of the fuse tube, and the buckle 30 is abutted against the bottom of the mounting seat, so that the rotating shaft can be limited in the mounting seat, and the fuse tube cannot fall off from the mounting seat when the fuse tube is pushed manually; the driving assembly 40 adopts a nut and a push rod, which not only can drive the buckle 30 to be close to or far away from the mounting seat, but also can position the buckle 30 so that the buckle 30 is continuously abutted against the mounting seat; the two hooks 20 respectively hook two ends of the rotating shaft, and the buckle 30 props against the bottom of the mounting seat, so that the rotating shaft and the mounting seat are more stable, and the rotating shaft is prevented from falling off from the mounting seat; the device also has the advantages of simple structure and convenient use.
