Description

Technical Field

[0001] The utility model relates to the technical field of fuse installation, in particular to a quick-installation excitation fuse mounting base. Background Art

[0002] With the development of power system technology, excitation fuses, as important electrical protection devices, play an indispensable role in ensuring the safe operation of circuits.

[0003] The traditional installation method of excitation fuses usually sets eagle beak hooks on the mounting base. As shown in Figure 1 shown, the eagle beak hooks can undergo elastic deformation to clamp the excitation fuse. This design can achieve the quick installation of the excitation fuse. However, when the fuse needs to be replaced or repaired, all the eagle beak hooks must be manually pried open to remove the fuse. This process is not only time-consuming and laborious, but also increases the operation difficulty and potential safety risks. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a quick-installation excitation fuse mounting base, which has a simple structure and can quickly stagger the eagle beak hooks from the excitation fuse, achieving the purpose of convenient removal of the excitation fuse.

[0005] A quick-installation excitation fuse mounting base of the utility model includes a base, and eagle beak hooks are elastically connected to both sides of the base. The end of the eagle beak hook connected to the base is denoted as the fixed end, and the other end is denoted as the movable end. It further includes:

[0006] A plurality of fixing pieces, each fixing piece corresponding to an eagle beak hook, and the fixing pieces are fixed to the movable ends; the end of the fixing piece away from the eagle beak hook extends downward to form an extension part;

[0007] Two driving components, symmetrically arranged on both sides of the base;

[0008] The driving component includes:

[0009] A rotating shaft, rotatably installed on the side surface of the base;

[0010] A driving rod, one end of which is fixed to the rotating shaft, and the other end is provided with a driving part; the driving part is located between the fixing piece and the eagle beak hook, and there is a certain distance between the driving part and the eagle beak hook;

[0011] It further includes a power component for driving the two rotating shafts to rotate in opposite directions.

[0012] As a preferred solution of the utility model, the driving part is a roller, and the roller is rotatably installed on the other end of the driving rod.

[0013] As a preferred solution of the utility model, a key is installed between the driving rod and the rotating shaft.

[0014] As a preferred solution of the utility model, the power assembly includes:

[0015] A track is fixed to the side of the base along the height direction of the base;

[0016] Two extension rods, one end of each of the two extension rods is fixedly connected to the end of the rotating shaft, and the other end of each of the two extension rods is fixedly connected to a fixed shaft;

[0017] The sliding plate is slidably mounted on the track; strip holes are provided on both sides of the sliding plate, and the fixed shaft passes through the strip holes.

[0018] As a preferred solution of the utility model, the power assembly also includes:

[0019] A fixed plate, fixedly connected to the bottom end of the track;

[0020] The lead screw is threadably connected to the fixing plate.

[0021] As a preferred solution of the utility model, the power assembly also includes:

[0022] A connecting plate, fixedly connected to the top of the track;

[0023] An elastic member, two ends of which are respectively connected to the connecting plate and the sliding plate.

[0024] As a preferred solution of the utility model, the middle part of the sliding plate extends outward to form a push-pull part, and the bottom of the push-pull part is provided with anti-slip grooves.

[0025] As a preferred solution of the utility model, a key is provided between the extension rod and the rotating shaft.

[0026] Compared with the prior art, the beneficial effects of the utility model are as follows: when installing the excitation fuse, the excitation fuse is inserted into the base. During this process, the hawk's beak hook undergoes elastic deformation under the extrusion of the excitation fuse due to the inclined top, and since the driving member is at a certain distance from the hawk's beak hook, the movement of the hawk's beak hook will not be hindered. When the excitation fuse is installed in place, the hawk's beak hook clamps the top surface of the excitation fuse to fix it; when the excitation fuse needs to be removed, the power assembly is operated to rotate the two shafts in opposite directions, and the shaft drives the drive rod and the driving member to rotate outward around the axis of the shaft, and the driving member contacts the extended portion of the fixed plate and pushes the fixed plate and the hawk's beak hook to rotate outward, so that the hawk's beak hook is disengaged from the excitation fuse, and then the excitation fuse can be removed. After the removal is completed, the power assembly is operated to restore the components to their initial states. Compared with the prior art, through the cooperation of the power assembly and the drive assembly, the hawk's beak hook can be quickly disengaged from the fuse without being manually pried apart, thereby reducing the disassembly time and complexity.

Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0036] Embodiment

[0037] Referring to Figures 2 - 5 , this embodiment provides a quick-installation excitation fuse 7 mounting seat, which includes a base 1. Eagle beak hooks 2 are elastically connected to both sides of the base 1. One end of the eagle beak hook 2 connected to the base 1 is denoted as the fixed end, and the other end is denoted as the movable end; It further includes:

[0038] A plurality of fixing pieces 3, each fixing piece 3 corresponding to an eagle beak hook 2, the fixing pieces 3 being fixed to the movable end; one end of the fixing piece 3 away from the eagle beak hook 2 extends downward to form an extension part 4;

[0039] Two driving components 5, symmetrically arranged on both sides of the base 1;

[0040] The driving component 5 includes:

[0041] A rotating shaft 51, rotatably installed on the side surface of the base 1;

[0042] A driving rod 52, one end of which is fixed to the rotating shaft 51, and the other end is provided with a driving part 53; the driving part 53 is located between the fixing piece 3 and the eagle beak hook 2, and there is a certain distance between the driving part 53 and the eagle beak hook 2, and there is also a certain distance between the top end of the driving part 53 and the fixing piece 3 to prevent interference during rotation;

[0043] It further includes a power component 6, and the power component 6 is used to drive the two rotating shafts 51 to rotate in opposite directions;

[0044] The specific operation process of this device is as follows: When installing the excitation fuse 7, insert the excitation fuse 7 into the base 1. During this process, since the top of the movable end of the eagle beak hook 2 is a slope, it undergoes elastic deformation under the extrusion of the excitation fuse 7, and because there is a certain distance between the driving part 53 and the eagle beak hook 2, it does not interfere with the movement of the eagle beak hook 2. When the excitation fuse 7 is installed in place, the eagle beak hook 2 catches the top surface of the excitation fuse 7 to fix it; when it is necessary to remove the excitation fuse 7, operate the power component 6 to make the two rotating shafts 51 rotate in opposite directions. The rotating shaft 51 drives the driving rod 52 and the driving part 53 to rotate outward around the axis of the rotating shaft 51. The driving part 53 contacts the extension part 4 of the fixing piece 3 and pushes the fixing piece 3 and the eagle beak hook 2 to rotate outward, so that the eagle beak hook 2 is separated from the excitation fuse 7, and then the excitation fuse 7 can be removed. After the removal is completed, operate the power component 6 to restore each component to its initial state. Compared with the prior art, through the cooperation of the power component 6 and the driving component 5, the eagle beak hook 2 can be quickly separated from the fuse, reducing the disassembly time and complexity.

[0045] If the driving part 53 and the driving rod 52 are fixedly connected, when the rotating shaft 51 rotates, there will be sliding friction between the driving part 53 and the extension part 4, generating a large amount of noise. To solve the above problems, as a preferred solution of the present invention, referring to Figure 2 and Figure 4 , the driving part 53 is a roller, and the roller is rotatably installed at the other end of the driving rod 52. The contact between the roller and the extension part 4 is rolling friction instead of sliding friction, significantly reducing the noise generated by friction.

[0046] As a preferred embodiment of the present utility model, a key is installed between the driving rod 52 and the rotating shaft 51, so that a key connection is formed between the driving rod 52 and the rotating shaft 51 to prevent relative rotation between the two.

[0047] As a preferred embodiment of the present utility model, referring to Figures 2 - 5 , the power assembly 6 includes:

[0048] Tracks 61, which are fixed to the side of the base 1 along the height direction of the base 1. To improve stability, two tracks 61 are provided;

[0049] Two extension rods 62, one ends of the two extension rods 62 are respectively fixedly connected to the ends of the rotating shaft 51, and the other ends are fixedly connected with a fixed shaft 63;

[0050] A sliding plate 64, which is slidably installed on the track 61; strip-shaped holes 65 are formed on both sides of the sliding plate 64, and the fixed shaft 63 passes through the strip-shaped holes 65;

[0051] The specific operation process of the power assembly 6 is as follows: when it is necessary to move the eagle beak hook 2 outward, hold the sliding plate 64 and move it upward along the track 61. Since the fixed shaft 63 passes through the strip-shaped hole 65, when the sliding plate 64 moves upward, the extension rod 62, the rotating shaft 51 and the driving rod 52 rotate synchronously; the power assembly 6 of this device can make the eagle beak hooks 2 on both sides move away from the excitation fuse 7 by simple pressing, which is very convenient.

[0052] If there is no limiting device at the bottom end of the track 61, the sliding plate 64 may be disengaged from the track 61, and the position of the driving member 53 cannot be fixed either. As a preferred embodiment of the present utility model, referring to Figure 3 and Figure 5 , the power assembly 6 further includes:

[0053] A fixing plate 66, which is fixedly connected to the bottom end of the track 61;

[0054] A lead screw 67, which is threadedly connected to the fixing plate 66;

[0055] Since the lead screw 67 and the fixing plate 66 are connected by a threaded connection, the relative position between the lead screw 67 and the fixing plate 66 can be adjusted, so that the lowest position of the sliding plate 64 can be adjusted. When the sliding plate 64 is at the lowest point, the driving member 53 and the eagle beak hook 2 just have a certain distance, which will not prevent the movement of the eagle beak hook 2. Through the cooperation of the lead screw 67 and the fixing plate 66, the position of the sliding plate 64 can be adjusted more conveniently, playing a role in facilitating debugging.

[0056] If there is no reset device, after the sliding plate 64 moves upward, it still needs to be manually reset. As a preferred embodiment of the present utility model, referring to Figures 3 - 4 , the power assembly 6 further includes:

[0057] A connecting plate 68, fixedly connected to the top end of the rail 61;

[0058] An elastic member 69, with both ends of the elastic member 69 connected to the connecting plate 68 and the sliding plate 64 respectively;

[0059] When the sliding plate 64 moves upward, the elastic member 69 will be further compressed. When the hand releases the sliding plate 64, under the elastic force of the elastic member 69, the sliding plate 64 moves downward until it contacts the end of the lead screw 67, playing a role of automatic reset.

[0060] As a preferred embodiment of the present invention, referring to Figure 4 , a pushing and pulling portion 610 extends outward from the middle of the sliding plate 64. Anti-slip lines are provided at the bottom of the pushing and pulling portion 610. The outward extension design of the pushing and pulling portion 610 provides a larger operating area, facilitating the operator to grasp with the hand, making the pushing and pulling actions easier and more convenient. The anti-slip lines provided at the bottom of the pushing and pulling portion 610 increase the friction between the hand and the pushing and pulling portion 610, preventing the hand from slipping during the operation and ensuring the stability and safety of the operation.

[0061] As a preferred embodiment of the present invention, a key is provided between the extension rod 62 and the rotating shaft 51, forming a key connection between the extension rod 62 and the rotating shaft 51 to prevent relative rotation between the two.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
