[0029] Referring to Figure 1 and Figure 2 , an auxiliary device 100 for replacing a fuse core is provided in an embodiment of the present application, including a fuse core fixing part 101, a push-pull telescopic part 102, a slide rail 103, and a power part 104. The fuse core fixing part 101 is used to clamp the fuse cap 11 of the fuse core 10. The push-pull telescopic part 102 is connected to the fuse core fixing part 101. The slide rail 103 cooperates with the push-pull telescopic part 102. The push-pull telescopic part 102 can move back and forth along the slide rail 103. The power part 104 is connected to the push-pull telescopic part 102 to provide power for the back-and-forth movement of the push-pull telescopic part 102 along the slide rail 103.

[0030] Specifically, as Figure 2 shown, when the fuse core 10 needs to be replaced, the fuse core fixing part 101 clamps the fuse cap 11 of the fuse core 10. The power part 104 is connected to the push-pull telescopic part 102, and the power part 104 provides power for the push-pull telescopic part 102, so that the push-pull telescopic part 102 slides along the slide rail 103, so that the fuse core fixing part 101 drives the fuse core 10 to move back and forth, so as to overcome the resistance between the fuse core 10 and the fuse barrel, facilitate the replacement of the fuse core 10, and improve the replacement efficiency of the fuse core 10.

[0031] Furthermore, referring again to Figure 1 , in some embodiments of the present application, the fuse core fixing part 101 is in a circular ring shape. The fuse core fixing part 101 includes two semi-circular ring parts 111, and the two semi-circular ring parts 111 are connected by a screw. The function of the fuse core fixing part 101 is to clamp the fuse cap 11 of the fuse core 10. The two semi-circular ring parts 111 can surround the fuse cap 11 of the fuse core 10, and the tightness can be adjusted by the screw, so as to clamp or release the fuse cap 11 of the fuse core 10, which is convenient for disassembly and assembly and facilitates the operation of the operator.

[0032] Furthermore, referring to Figure 2 , in some embodiments of the present application, the height of the fuse core fixing part 101 from the ground is the same as the installation height of the fuse core 10.

[0033] That is, the fuse core fixing part 101 can align the fuse core 10 with the fuse barrel, so that the operator can directly replace the fuse core 10 on the ground, which is beneficial to improving the replacement efficiency of the fuse core 10.

[0034] Furthermore, referring to Figure 1 , in some embodiments of the present application, the fuse core fixing part 101 further includes a slider 112. The slider 112 is connected to the semi-circular ring part 111, and the slider 112 is used in cooperation with the slide rail 103.

[0035] Specifically, the function of the slider 112 is to cooperate with the slide rail 103, so that the fuse core fixing part 101 can drive the fuse core 10 to move back and forth along the slide rail 103, so as to overcome the resistance between the fuse core 10 and the fuse barrel, facilitate the replacement of the fuse core 10, and further improve the replacement efficiency of the fuse core 10.

[0036] Furthermore, referring to Figure 1, in some embodiments of the present application, the number of slide rails 103 is two. The two slide rails 103 are arranged in parallel, and the openings of the two slide rails 103 face each other. The slide rail 103 is used to provide a track for the reciprocating movement of the core fixing part 101, so that the core fixing part 101 can drive the core 10 to reciprocate along the slide rail 103, overcome the resistance between the core 10 and the melting cylinder, facilitate the replacement of the core 10, and further improve the replacement efficiency of the core 10.

[0037] Furthermore, in some embodiments of the present application, the semi-circular ring part 111 and the slider 103 of the core fixing part 101 are of an integrally formed structure.

[0038] Specifically, the semi-circular ring part 111 and the slider 103 of the core fixing part 101 can be made of plastic or metal materials, etc., and integrally formed by injection molding or compression molding, etc., so as to reduce the manufacturing cost of the core fixing part 101 and simplify its manufacturing process.

[0039] Furthermore, referring back to Figure 1 , in some embodiments of the present application, the power unit 104 includes a rocking wheel 141 and a transmission rod 142. The rocking wheel 141 transmits power to the push-pull telescopic part 102 through the transmission rod 142. The rocking wheel 141 includes a rocker and a roller disc. When the core 10 needs to be replaced, the operator rocks the rocker, thereby driving the roller disc to rotate, and transmits the power to the push-pull telescopic part 102 through the transmission rod 142, so that the core fixing part 101 drives the core 10 to slide back and forth along the slide rail 103, overcome the resistance between the core 10 and the melting cylinder, facilitate the replacement of the core 10, and improve the replacement efficiency of the core 10.

[0040] It should be noted that Figure 1 the power unit 104 shown is only an example. The power unit 104 can also adopt other forms and structures, and the power unit 104 can also provide power in an automatic rather than manual manner.

[0041] Furthermore, referring to Figure 1 and Figure 2 , in some embodiments of the present application, the core replacement auxiliary device 100 further includes a fixing frame 105. The slide rail 103 and the rocking wheel 141 are installed on the fixing frame 105. The function of the fixing frame 105 is to fix related components, such as the slide rail 103 and the rocking wheel 141, etc., so as to provide a supporting effect for related components.

[0042] Furthermore, referring to Figure 1, in some embodiments of the present application, the fixing bracket 105 includes support legs 151 and a main body portion 152. The support legs 151 are connected to the main body portion 152, and the slide rail 103 is provided on the main body portion 152. The main body portion 152 has a structure with one end open, and the fuse core fixing portion 101 and the push-pull telescopic portion 102 are accommodated in the main body portion 152.

[0043] Specifically, the main body portion 152 of the fixing bracket 105 has a structure with one end open, so as to provide a movement space for the back-and-forth sliding of the fuse core fixing portion 101 and the push-pull telescopic portion 102, thereby facilitating the fuse core fixing portion 101 to drive the fuse core 10 to move back and forth to overcome the resistance between the fuse core 10 and the fuse barrel, facilitating the replacement of the fuse core 10, and improving the replacement efficiency of the fuse core 10. The support legs 151 of the fixing bracket 105 are used to provide support for the main body portion 152.

[0044] Further, referring again to Figure 1 , in some embodiments of the present application, the handwheel 141 is fixed on the support leg 151 of the fixing bracket 105. When the fuse core 10 needs to be replaced, the operator only needs to rotate the handwheel 141 in the clockwise or counterclockwise direction. The handwheel 141 is fixed on the support leg 151 of the fixing bracket 105, and its installation height is suitable for the manual operation of the operator. The operator can directly stand on the ground to complete the replacement of the fuse core 10.

[0045] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the inventive concept of the present application, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
