Description

Technical Field

[0001] This utility model relates to the field of replacement device technology, specifically a fuse quick replacement device. Background Technology

[0002] When a circuit malfunctions or malfunctions, the current continuously increases, potentially damaging critical components, burning out the circuit, or even causing a fire. If a fuse is correctly installed in the circuit, it will melt and break the current when the current abnormally rises to a certain level and temperature, thus protecting the circuit's safe operation.

[0003] For example, the outdoor high-voltage current-limiting fuse replacement device disclosed in the authorization announcement number CN210110691U includes a housing, a threaded pressure rod and a fixing device. The housing is provided with a cavity for accommodating the fuse sleeve. The threaded pressure rod is threadedly connected to the housing. The fixing device is used to connect the housing and the fuse sleeve.

[0004] Although it enables one person to operate the outdoor high-voltage current-limiting fuse replacement device independently and improves work efficiency.

[0005] However, this does not solve the problem that existing replacement devices of this type are generally not conducive to the convenient and quick replacement and installation of fuses, do not provide convenient and stable support for the fuses, and do not provide convenient elastic support and protection for the fuses, thus affecting the safety of fuse installation and replacement. Utility Model Content

[0006] The purpose of this utility model is to provide a quick fuse replacement device to solve the problems mentioned in the background art, such as the inconvenience of the replacement device in making it easy and quick to replace and install fuses, the inconvenience of the replacement device in providing convenient and stable support for fuses, and the inconvenience of the replacement device in providing convenient elastic support and protection for fuses, which affect the safety of fuse installation and replacement.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A quick fuse replacement device includes a base and lower mounting arms. The lower mounting arms are symmetrically mounted on the top of the base. Upper mounting arms are movably mounted on the outer walls of the lower mounting arms. A fuse body is disposed between the two sides of the lower mounting arms above the base. A second limiting bracket is mounted on the outer wall of each upper mounting arm. A first limiting bracket is mounted on the outer wall of the lower mounting arm on one side of the second limiting bracket. A drive shaft is mounted on the outer wall of the first limiting bracket near the second limiting bracket, and the first limiting bracket is movably connected to the second limiting bracket via the drive shaft. An upper mounting bracket is mounted on the outer wall of the upper mounting arm away from the drive shaft. An upper limit seat is mounted on the top of each upper mounting bracket. An upper spring is mounted on the top of each upper limit seat. An upper flip shaft is movably mounted on the top of each upper limit seat. Upper buckles are symmetrically fitted onto the surface of each upper flip shaft.

[0009] Optionally, each of the upper buckles has an upper mounting hole on its outer wall, and the upper spring extends through the upper mounting hole to the outside of the upper buckle.

[0010] Optionally, an upper buckle groove is provided on the outer wall of the side away from the upper mounting hole, and a lower mounting bracket is installed on the outer wall of the lower mounting arm on the side of the upper mounting bracket.

[0011] Optionally, a lower limit seat is installed on the outer wall of the lower mounting bracket, and a lower flip shaft is movably installed on the top of the lower limit seat. The surface of the lower flip shaft is symmetrically fitted with lower buckles.

[0012] Optionally, a lower spring is installed on the outer wall of the lower limit seat, and a lower mounting hole is provided on the outer wall of the lower buckle.

[0013] Optionally, a lower latch groove is provided on the outer wall of the lower latch on the side away from the lower mounting hole, and the lower spring extends to the outside of the lower latch through the lower mounting hole.

[0014] Optionally, each of the upper mounting arms is provided with a first supporting arc-shaped arm on the outer side away from the lower mounting frame, and a connecting wire is installed on the outer wall of each of the first supporting arc-shaped arms.

[0015] Optionally, multiple sets of first springs with equal spacing are installed on the outer wall of the first supporting arc arm on one side of the lower mounting arm, and one end of the first spring is connected to the first supporting arc arm, and the other end of the first spring is connected to the lower mounting arm.

[0016] Optionally, a second supporting arc arm is provided on the outside of the upper mounting arm above the first supporting arc arm, and multiple sets of second springs with equal spacing are installed on the outer wall of the second supporting arc arm.

[0017] Optionally, one end of the second spring is connected to the second supporting arc arm, and the other end of the second spring is connected to the first supporting arc arm.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the replacement device not only realizes the convenient and quick replacement and installation of fuses, and facilitates the convenient and stable support of fuses by the replacement device, but also facilitates the convenient elastic support and protection of fuses by the replacement device, thereby improving the safety during fuse installation and replacement.

[0019] The fuse body is placed on the surface of the two sets of first support arc arms. The upper mounting arm is manually rotated, which drives the second limiting bracket to rotate, facilitating the rotation of the upper mounting arm around the drive shaft. The second and first limiting brackets provide movable support for the drive shaft, facilitating the movement of the upper latch to the lower latch side. The two sets of upper latches are manually pushed, facilitating their rotation around the upper flip shaft. The upper mounting bracket supports the upper limit seat, which in turn provides movable support for the upper flip shaft, facilitating the movement of the upper latch to the lower flip shaft side. This allows the lower flip shaft to connect with the upper latch in cooperation with the upper slot, thus securing the upper mounting arm. The upper spring piece provides elastic limiting support for the upper latch through the upper mounting hole, preventing the upper latch from detaching from the surface of the lower flip shaft. The lower latch is manually pushed, facilitating its rotation around the lower flip shaft. Supported by the lower mounting bracket, the lower limit seat provides movable support for the lower flip shaft. The lower latch is designed to facilitate movement to the upper flip shaft side, allowing for connection between the lower latch and the upper flip shaft through the cooperation of the lower latch slot. The lower spring clip provides limiting support for the lower latch via the lower mounting hole, preventing it from detaching from the surface of the upper flip shaft. This facilitates the installation of the fuse body. When the fuse body needs to be removed, the two sets of upper and lower spring clips are manually pulled. When the manual pulling force exceeds the elasticity of the upper and lower spring clips, they no longer limit the upper and lower latches. The upper and lower latches are then manually rotated to detach from the surfaces of the lower and upper flip shafts. This allows for the removal of the fuse body from the surface of the first support arc arm by manually rotating the upper mounting arm. This enables convenient and quick fuse replacement and installation using the replacement device, providing convenient and stable support for the fuse, preventing it from falling off due to aging, and improving the convenience of fuse support and fixation.

[0020] When the fuse body is placed on the surface of the first support arc arm, the first springs provide elastic support to the first support arc arm under the support of multiple sets of first springs on the lower mounting arm, and the second springs provide elastic support to the second support arc arm under the support of multiple sets of second springs on the upper mounting arm. This facilitates the elastic support and protection of the fuse body by the first and second support arc arms, realizing convenient elastic support and protection of the fuse by the replacement device, avoiding damage during fuse replacement and installation, and improving the safety of fuse installation and replacement.

[0041] like Figures 1 to 9 As shown, an embodiment of this utility model provides a quick fuse replacement device, including a base 1 and a lower mounting arm 2. The lower mounting arms 2 are symmetrically mounted on the top of the base 1. Upper mounting arms 3 are movably mounted on the outer walls of the lower mounting arms 2. A fuse body 4 is disposed between the two sides of the lower mounting arms 2 above the base 1. A second limiting bracket 7 is mounted on the outer wall of each upper mounting arm 3. A first limiting bracket 5 is mounted on the outer wall of the lower mounting arm 2 on one side of the second limiting bracket 7. A drive shaft 6 is mounted on the outer wall of the first limiting bracket 5 near the second limiting bracket 7, and the first limiting bracket 5 is movably connected to the second limiting bracket 7 via the drive shaft 6. An upper mounting bracket 11 is mounted on the outer wall of the upper mounting arm 3 away from the drive shaft 6. An upper limit seat 12 is mounted on the top of each upper mounting bracket 11. An upper spring 13 is mounted on the top of each upper limit seat 12. An upper spring 13 is movably mounted on the top of each upper limit seat 12. The upper rotating shaft 16 has upper buckles 14 symmetrically fitted on its surface. The outer wall of the upper buckle 14 is provided with upper mounting holes 17, and the upper spring piece 13 extends through the upper mounting holes 17 to the outside of the upper buckle 14. The outer wall of the upper buckle 14 away from the upper mounting holes 17 is provided with upper slots 15. The lower mounting arm 2 on one side of the upper mounting bracket 11 is provided with a lower mounting bracket 18. The outer wall of the lower mounting bracket 18 is provided with a lower limit seat 19. The top of the lower limit seat 19 is movably mounted with a lower rotating shaft 22. The surface of the lower rotating shaft 22 is symmetrically fitted with lower buckles 23. The outer wall of the lower limit seat 19 is provided with a lower spring piece 20. The outer wall of the lower buckle 23 is provided with a lower mounting hole 24. The outer wall of the lower buckle 23 away from the lower mounting hole 24 is provided with a lower slot 21. The lower spring piece 20 extends through the lower mounting hole 24 to the outside of the lower buckle 23.

[0042] When the fuse body 4 is damaged and needs to be replaced, place the fuse body 4 on the surface of the two sets of first support arc arms 9, and manually rotate the upper mounting arm 3. The upper mounting arm 3 drives the second limiting frame 7 to rotate, so that the upper mounting arm 3 can rotate around the drive shaft 6. The second limiting frame 7 and the first limiting frame 5 provide movable support for the drive shaft 6, so that the upper latch 14 can move to the side of the lower latch 23. Manually push the two sets of upper latches 14 to facilitate the rotation of the upper latches 14 around the upper flip shaft 16. The upper mounting frame 11 supports the upper limit seat 12. The upper limit seat 12 provides movable support for the upper flip shaft 16, facilitating the movement of the upper latch 14 to the side of the lower flip shaft 22. This allows for the connection between the lower flip shaft 22 and the upper latch 14 through the cooperation of the upper latch slot 15 and the lower flip shaft 22, thus facilitating the fixation of the upper mounting arm 3. The upper spring piece 13 provides elastic limiting support for the upper latch 14 through the upper mounting hole 17, preventing the upper latch 14 from falling off the surface of the lower flip shaft 22. The lower latch 23 is manually pushed to allow it to rotate around the lower flip shaft 22. Supported by the lower mounting bracket 18, the lower limit seat... 19. The lower flip shaft 22 is provided with movable support to facilitate the movement of the lower latch 23 to the side of the upper flip shaft 16. This allows the lower latch 23 to be connected to the upper flip shaft 16 through the cooperation of the lower latch slot 21. The lower spring 20 provides limiting support for the lower latch 23 through the lower mounting hole 24 to prevent the lower latch 23 from falling off the surface of the upper flip shaft 16, thus facilitating the installation of the fuse body 4. When it is necessary to remove the fuse body 4, the two sets of upper springs 13 and lower springs 20 are manually pulled. When the manual pulling force exceeds the force of the upper springs 13 and lower springs 20... When the spring force is applied, the upper spring piece 13 and the lower spring piece 20 no longer limit and support the upper buckle 14 and the lower buckle 23. The upper buckle 14 and the lower buckle 23 can be manually rotated to facilitate their disengagement from the surfaces of the lower flip shaft 22 and the upper flip shaft 16. This allows the fuse body 4 on the surface of the first support arc arm 9 to be easily removed by manually rotating the upper mounting arm 3. This enables the replacement device to easily and quickly replace and install the fuse, provides convenient and stable support for the fuse, prevents the fuse from falling off due to aging, and improves the convenience of fuse support and fixation.

[0043] Each upper mounting arm 3 has a first supporting arc arm 9 on the side away from the lower mounting bracket 18. Each first supporting arc arm 9 has a connecting wire 10 installed on its outer wall. Each first supporting arc arm 9 on the side of the lower mounting arm 2 has multiple sets of first springs 8 installed at equal intervals on its outer wall. One end of each first spring 8 is connected to the first supporting arc arm 9, and the other end of each first spring 8 is connected to the lower mounting arm 2. Each upper mounting arm 3 above the first supporting arc arm 9 has a second supporting arc arm 25 on its outer wall. Each second supporting arc arm 25 has multiple sets of second springs 26 installed at equal intervals on its outer wall. One end of each second spring 26 is connected to the second supporting arc arm 25, and the other end of each second spring 26 is connected to the first supporting arc arm 9.

[0044] When the fuse body 4 is placed on the surface of the first supporting arc arm 9, the first spring 8 provides elastic support to the first supporting arc arm 9 under the support of multiple sets of first springs 8 on the lower mounting arm 2, and the second spring 26 provides elastic support to the second supporting arc arm 25 under the support of multiple sets of second springs 26 on the upper mounting arm 3. This facilitates the elastic support and protection of the fuse body 4 by the first supporting arc arm 9 and the second supporting arc arm 25, realizing convenient elastic support and protection of the fuse by the replacement device, avoiding damage during fuse replacement and installation, and improving the safety of fuse installation and replacement.

[0045] The working principle of the technical solution provided by this utility model is as follows: Two sets of connecting wires 10 are connected to external wires. When the fuse body 4 is damaged and needs to be replaced, the fuse body 4 is placed on the surface of the two sets of first support arc arms 9. The upper mounting arm 3 is manually rotated, which drives the second limiting frame 7 to rotate, so that the upper mounting arm 3 can rotate around the drive shaft 6. The second limiting frame 7 and the first limiting frame 5 provide movable support for the drive shaft 6, so that the upper buckle 14 can move to the side of the lower buckle 23. The two sets of upper buckles 14 are manually pushed, so that the upper buckles 14 can rotate around the upper flip shaft 16. The upper mounting frame 11 moves against the upper limit seat 12. The upper limit seat 12 provides movable support for the upper flip shaft 16, facilitating the movement of the upper latch 14 to the side of the lower flip shaft 22. This allows for the connection between the lower flip shaft 22 and the upper latch 14 through the cooperation of the upper latch slot 15 and the lower flip shaft 22, thus securing the upper mounting arm 3. The upper spring piece 13 provides elastic limiting support for the upper latch 14 through the upper mounting hole 17, preventing the upper latch 14 from detaching from the surface of the lower flip shaft 22. The lower latch 23 can be manually pushed to rotate around the lower flip shaft 22. Supported by the lower mounting bracket 18, the lower limit seat 19 provides movable support for the lower flip shaft 22, facilitating the movement of the lower latch 23 to the upper... On one side of the flip shaft 16, the lower latch 23 is connected to the upper flip shaft 16 through the cooperation of the lower latch 21 and the upper flip shaft 16. The lower spring 20 limits and supports the lower latch 23 through the lower mounting hole 24 to prevent the lower latch 23 from falling off the surface of the upper flip shaft 16, thus facilitating the installation of the fuse body 4. When it is necessary to remove the fuse body 4, the two sets of upper spring 13 and lower spring 20 are manually pulled. When the manual pulling force exceeds the elastic force of the upper spring 13 and the upper and lower spring 20, the upper spring 13 and the lower spring 20 no longer limit and support the upper latch 14 and the lower latch 23. The upper latch 14 and the lower latch 23 are then manually rotated to facilitate the connection between the upper latch 14 and the lower latch 23. The buckle 23 detaches from the surfaces of the lower flip shaft 22 and the upper flip shaft 16, allowing the fuse body 4 to be easily removed from the surface of the first support arc arm 9 by manually rotating the upper mounting arm 3. When the fuse body 4 is placed on the surface of the first support arc arm 9, the first spring 8 provides elastic support to the first support arc arm 9 under the support of multiple sets of first springs 8 on the lower mounting arm 2, and the second spring 26 provides elastic support to the second support arc arm 25 under the support of multiple sets of second springs 26 on the upper mounting arm 3. This facilitates the elastic support and protection of the fuse body 4 by the first support arc arm 9 and the second support arc arm 25, thus completing the use of the replacement device.
