[0044] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0045] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, mechanical or electrical connections, direct or indirect connections through an intermediate medium, and internal communication between two elements or interaction between two elements. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0046] In the description of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0047] In the prior art, drop-out fuses usually include a mounting bracket, a fuse tube, an upper cover groove, a lower bracket, a terminal, a guide hook, and an operating ring. In the daily maintenance of drop-out fuses, an operating lever with a fixed horizontal iron or a clamp is often used to remove the fuse tube in the fuse. However, due to the high installation position of the fuse, when the operating lever is used for removal, the fuse tube is easily separated from the horizontal iron or the clamp during transportation, causing damage to parts and threatening the personal safety of the operator. For the disassembly and assembly of fuse tubes at different installation angles at high places, multiple disassembly and assembly using only the operating lever is inefficient and wastes manpower.

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0049] Example 1

[0050] like Figures 1-9As shown, the present invention provides a device for disassembling and assembling a drop-type fuse tube, which mainly includes a base 10, a support rod 20, a clamping seat 30, a position adjustment assembly 40, an angle adjustment assembly 50 and a clamping adjustment assembly 60. The support rod 20 is slidably connected to the base 10 along a first direction, the clamping seat 30 is rotatably connected to the support rod 20, and the clamping seat 30 extends along a second direction relative to the rotation axis of the support rod 20, the second direction is perpendicular to the first direction, and a clamping space is provided on the clamping seat 30. The position adjustment assembly 40 is provided on the base 10 and is configured to adjust the position of the support rod 20 relative to the base 10. The angle adjustment assembly 50 is respectively connected to the support rod 20 and the clamping seat 30 and is configured to adjust the angle between the clamping seat 30 and the support rod 20. The clamping adjustment assembly 60 is provided on the clamping seat 30, and the output end of the clamping adjustment assembly 60 can extend into the clamping space.

[0051] In this embodiment, the base 10 provides stable support, and the support rod 20 supports and connects the clamping seat 30. The clamping seat 30 is provided with a clamping space for clamping the molten tube. The clamping seat 30 is rotatably connected to the support rod 20 and can rotate in the second direction, thereby achieving up and down swinging of the two ends of the clamping seat 30, thereby adjusting the clamping angle and position.

[0052] The position adjustment assembly 40 can adjust the position of the support rod 20 relative to the base 10, thereby changing the height of the clamping base 30 relative to the base 10, bringing the clamping base 30 closer to the molten tube installation location for easier removal. The angle adjustment assembly 50 is configured to adjust the swing angle of the clamping base 30, providing the structural basis for the swing requirement. The output end of the clamping adjustment assembly 60 can extend into the clamping space to clamp or release the molten tube.

[0053] The overall structure of the device for disassembling and assembling the fuse tube of a drop-out type fuse according to this embodiment is described below.

[0054] like Figure 1 As shown, the drop-out type fuse tube disassembly and assembly device in this embodiment is connected to the base 10, the support rod 20 and the clamping seat 30 in sequence from bottom to top. The position adjustment assembly 40 is rotatably connected to the base 10 and is configured to drive the support rod 20 to move in a first direction relative to the base 10. The angle adjustment assembly 50 is adjustably connected to the support rod 20 and rotatably connected to one end of the clamping seat 30, and is used to drive the two ends of the clamping seat 30 to rotate. The clamping adjustment assembly 60 is configured to be rotatably connected to the support rod 20 and partially disposed in the clamping seat 30, and is configured to tightly clamp the fuse tube in the clamping space.

[0055] Specifically, if Figure 2As shown, the base 10 includes a base platform 11 and a support tube 12. In this embodiment, the base platform 11 is configured as a circular platform to increase the contact area between the device and the ground, ensuring the stability of the device during operation. The support tube 12 is configured as a hollow cylindrical structure with one end open, so that the support rod 20 can slide and move within the support tube 12.

[0056] In this embodiment, the support rod 20 is slidably connected to the support tube 12 in the base 10. Optionally, a protrusion is provided at one end of the support rod 20, which is provided as an annular protrusion in this embodiment, and may also be provided with protrusions at intervals in other embodiments.

[0057] Specifically, a connecting hole is provided at the open end of the support tube 12, the diameter of which is smaller than the diameter of the inner wall of the support tube 12 and the diameter of the annular protrusion of the support rod 20, but larger than the diameter of the support rod 20. As a result, the annular protrusion of the support rod 20 can slide within the support tube 12 and abut against the open end of the support tube 12, preventing the support rod 20 from escaping from the support tube 12, limiting the adjustment range of the position adjustment assembly 40 and preventing operational accidents caused by the separation of the device.

[0058] like Figure 3 As shown, the support rod 20 includes a lower support rod 21 , an upper support rod 22 and a connecting frame 23 , wherein the upper support rod 22 includes a first hinge seat 221 and a pin shaft 222 .

[0059] Optionally, the lower support rod 21 is slidably connected to the base 10 , and an annular protrusion is provided at one end of the lower support rod 21 to prevent it from falling off.

[0060] Combine Figure 8 As shown, the upper support rod 22 is rotatably connected to the clamping base 30. Specifically, the upper support rod 22 is provided with a first hinge seat 221. Two first hinge seats 221 are symmetrically spaced apart at one end of the upper support rod 22. The bottom plate of the clamping base 30 is provided with elongated holes extending along a first direction. The two elongated holes are spaced apart and arranged in parallel. The size of the elongated holes is larger than that of the first hinge seats 221, so that the first hinge seats 221 can be smoothly inserted into the elongated holes.

[0061] The two first hinge seats 221 of the upper support rod 22 are respectively provided in the two elongated holes of the clamping seat 30. The pin shaft 222 is configured to be rotatably connected to the first hinge seats 221.

[0062] Optionally, a hinge hole is provided on the first hinge seat 221. After the first hinge seat 221 passes through the elongated hole and enters the interior of the clamping seat 30, a pin 222 is correspondingly passed through the hinge hole and fixedly connected to the inner wall of the clamping seat 30, so that the first hinge seat 221 is rotatably connected to the clamping seat 30 and cannot fall out of the elongated hole. This rotatable connection between the support rod 20 and the clamping seat 30 ensures smooth adjustment of the angle adjustment assembly 50, thereby exerting a better clamping force on the molten tubes placed at different angles.

[0063] like Figure 3 As shown, the upper support rod 22 is rotatably connected to the clamping and adjusting assembly 60. The connecting frame 23 is fixedly connected to the lower support rod 21 and the upper support rod 22. Under the action of the connecting frame 23, when the clamping and adjusting assembly 60 rotates relative to the upper support rod 22, the position of the upper support rod 22 relative to the lower support rod 21 does not change. In this embodiment, the connecting frame 23 is configured as a U-shaped structure, but in other embodiments, it can also be configured as a fixed structure of other shapes.

[0064] like Figure 4 As shown, the clamping seat 30 includes a clamping frame 31 and a clamping plate 32 , wherein the clamping frame 31 is provided with a protrusion 311 .

[0065] Specifically, the clamping frame 31 is designed as a hollow structure, facilitating overall weight reduction and the placement of other components. The clamping adjustment assembly 60 is housed within the clamping frame 31 to protect it from environmental contamination. An elongated hole is provided at the bottom of the clamping frame 31, where the first hinged seat 221 is pivotally connected, and the pin 222 is fixedly attached to the inner wall of the clamping frame 31.

[0066] like Figure 4 As shown, the clamping frame 31 is provided with a raised portion 311 at one end along the third direction, which is perpendicular to the second direction. The angle adjustment assembly 50 is connected to the raised portion 311, facilitating application of force to the clamping frame 31 as a whole, thereby increasing the swing amplitude. In this embodiment, a clamping plate 32 is fixedly attached to the side opposite the raised portion 311. The clamping plate 32 is configured as an arc-shaped plate, and the clamping plate 32 and the clamping frame 31 enclose a clamping space extending along the first direction.

[0067] Optionally, the clamping space is provided with an opening along one side of the second direction to facilitate the entry of the molten tube into the clamping space through the opening and to be precisely clamped by the device under the guidance of the curved structure of the clamping plate 32. The size of the clamping space is not less than the outer diameter of the molten tube. In other embodiments, the position and angle between the clamping plate 32 and the clamping frame 31 can also be adjusted to accommodate the assembly and disassembly of molten tubes of different sizes.

[0068] like Figure 5 As shown, the position adjustment assembly 40 includes a transmission shaft 41 , a transmission gear 42 and a first rack 43 .

[0069] Specifically, a transmission shaft 41 is disposed on the base 10. In this embodiment, the transmission shaft 41 is rotatably connected to the support tube 12. An access hole is defined in the sidewall of the support tube 12, through which the transmission shaft 41 passes to connect to the transmission gear 42. The device for driving the transmission shaft 41 is conventional in the art and will not be further described here.

[0070] like Figure 5As shown, in this embodiment, a first rack 43 is provided on the support rod 20 and extends along a first direction. The transmission gear 42 is connected to the transmission shaft 41 and meshes with the first rack 43. When the transmission shaft 41 rotates relative to the support tube 12, it drives the transmission gear 42 to rotate, and the first rack 43 moves accordingly under the meshing action. Driven by the first rack 43, the support rod 20 slides within the support tube 12 along the first direction, thereby changing the position of the support rod 20 relative to the base platform 11, and achieving a height change of the clamping seat 30 to be closer to the installation location of the melting tube, facilitating disassembly and assembly.

[0071] Furthermore, the first rack 43 is arranged on the lower support rod 21, and the lower support rod 21 slides in the support tube 12 along the first direction under the drive of the first rack 43. Under the connection action of the connecting frame 23, the upper support rod 22 moves in the first direction accordingly, and causes the clamping seat 30 rotatably connected to it to move up and down.

[0072] like Figure 2 As shown, the angle adjustment assembly 50 includes a support member 51, a first transmission rod 52 and a second hinge seat 53. Figure 3 As shown, an annular groove 511 is provided on the support member 51 .

[0073] In this embodiment, the support member 51 is configured to be adjustable in position along the first direction and connected to the support rod 20. Specifically, the lower support rod 21 is provided with an external thread, the support member 51 is configured as a cylinder, and the support member 51 is provided with an internal thread inside the cylinder. The internal thread of the support member 51 can be screwed into the external thread of the lower support rod 21, that is, the support member 51 can be screwed to the lower support rod 21.

[0074] By screwing, the support member 51 is positionally adjustable on the lower support rod 21, and the angle adjustment assembly 50 as a whole is positionally changed relative to the lower support rod 21 in the first direction. In other embodiments, other position-changing adjustment methods such as snap-fitting may also be used.

[0075] Optionally, one end of the first transmission rod 52 is connected to the support member 51, and the other end is rotatably connected to the clamping seat 30. Therefore, when the support member 51 changes position on the lower support rod 21, the first transmission rod 52 can change position accordingly to provide a force in the first direction to the end connected to the clamping seat 30.

[0076] Optionally, in this embodiment, the first transmission rod 52 is configured as an L-shaped long rod, one end of the short rod is slidably connected to the support member 51 along the circumferential direction, and one end of the long rod is rotatably connected to the protrusion 311 of the clamping frame 31. Figure 3 As shown, an annular groove 511 is circumferentially provided on the outer wall of the support member 51 , and one end of the short rod of the first transmission rod 52 is limited in the annular groove 511 .

[0077] When the support member 51 rotates on the lower support rod 21, the first transmission rod 52 slides relative to the support member 51 in the annular groove 511. Without external force, the first transmission rod 52 does not rotate relative to the lower support rod 21. Under the action of the groove wall of the annular groove 511, the first transmission rod 52 and the support member 51 move up and down together in the first direction to achieve position change.

[0078] Furthermore, the second hinged seat 53 is fixed to the raised portion 311, and one end of the long rod of the first transmission rod 52 is rotatably connected to the second hinged seat 53. When the first transmission rod 52 moves relative to the lower support rod 21 in the first direction along with the support member 51, the first transmission rod 52 pulls down or lifts up the second hinged seat 53, causing the raised portion 311 to rotate and swing along the axis in the second direction, thereby changing the angle between the clamping seat 30 and the upper support rod 22, thereby better approaching the molten pipe for clamping operation.

[0079] like Figure 3 As shown, the clamping and adjusting assembly 60 includes an adjusting mechanism 61, a transmission mechanism 62 and a clamping mechanism 63. Specifically, as Figure 6 As shown, the adjustment mechanism 61 includes a second sleeve 611 , a positioning bead 612 and a first elastic member 613 .

[0080] In this embodiment, the adjustment mechanism 61 is rotatably connected to the support rod 20. The ends of the adjustment mechanism 61 are rotatably connected to the lower support rod 21 and the upper support rod 22, respectively. Under the action of the connecting frame 23, when the adjustment mechanism 61 rotates relative to the lower support rod 21 and the upper support rod 22, the relative positions of the lower support rod 21 and the upper support rod 22 do not change.

[0081] Specifically, if Figure 3 As shown, the second sleeve 611 is sleeved on the support rod 20. In this embodiment, the second sleeve 611 is cylindrical, and a baffle is provided in the middle of the second sleeve 611. The baffle divides the second sleeve 611 into two chambers, namely a first chamber and a second chamber.

[0082] Optionally, one end of the lower connecting rod 21 is rotatably connected to the second sleeve 611 in the first chamber, and one end of the upper connecting rod 22 is rotatably connected to the second sleeve 611 in the second chamber, so that the second sleeve 611 rotatably connects the lower connecting rod 21 and the upper connecting rod 22 together.

[0083] Furthermore, a limiting groove is provided on the inner wall of the second sleeve 611. In this embodiment, the limiting groove is configured as an arcuate groove. Multiple arcuate grooves are provided in each of the first and second chambers. Specifically, the multiple arcuate grooves in the first chamber are evenly distributed along the circumference of the inner wall of the second sleeve 611, and the multiple arcuate grooves in the second chamber are also evenly distributed along the circumference of the inner wall of the second sleeve 611.

[0084] Similarly, the outer walls of the lower support rod 21 and the upper support rod 22 are provided with placement grooves, which correspond to the limiting grooves one by one, and the size of the placement grooves is larger than the limiting grooves. Figure 6 As shown, one end of the first elastic member 613 is fixed to the bottom of the placement groove, and the other end is connected to the positioning bead 612. The positioning bead 612 is configured to extend into the limiting groove to interfere with the rotation of the second sleeve 611 relative to the support rod 20.

[0085] Specifically, the first elastic member 613 is configured as a spring. The positioning bead 612 is fixedly connected to the spring. When the spring is compressed, a portion of the positioning bead 612 is located within the positioning groove. The arc diameter of the retaining groove is slightly larger than the outer diameter of the positioning bead 612, thereby ensuring that the positioning bead 612 extends into the retaining groove and does not fall out.

[0086] The abutment and interference of the multiple positioning beads 612 and the first elastic member 613 allows the second sleeve 611 to be stably fixed in any position during rotation relative to the lower support rod 21 and the upper support rod 22, thereby locking the molten tube when clamped and preventing it from falling out. At the same time, the positioning beads 612, the second sleeve 611, and the connecting frame 23 provide multiple connections between the lower support rod 21 and the upper support rod 22, preventing them from separating and improving the operational stability of the device.

[0087] Furthermore, in this embodiment, both ends of the transmission mechanism 62 are respectively connected to the adjustment mechanism 61 and the clamping mechanism 63. When the adjustment mechanism 61 rotates on the support rod 20, the clamping mechanism 63 can extend into the clamping space under the drive of the transmission mechanism 62.

[0088] like Figure 7 and Figure 8 As shown, the transmission mechanism 62 includes a worm 621 , a universal joint 622 , a worm wheel 623 , a second transmission rod 624 , a half-tooth gear 625 and a second rack 626 .

[0089] Specifically, the universal joint 622 is connected to the worm 621 and the adjustment mechanism 61, respectively. In this embodiment, one end of the universal joint 622 is fixedly connected to a partition in the second sleeve 611 and disposed within the upper support rod 22. The other end is connected to the worm 621 and disposed within the clamping frame 31. When the second sleeve 611 rotates relative to the lower support rod 21 and the upper support rod 22, the universal joint 622, driven by the second sleeve 611, drives the worm 621 at its other end to rotate, achieving power transmission.

[0090] Furthermore, when the angle adjustment assembly 50 pulls the clamping seat 30 to swing, the worm 621 swings accordingly, and the angle between it and the upper support rod 22 changes. At this time, the second sleeve 611 is rotated, and the worm 621 can rotate under the action of the universal joint 622, thereby achieving effective power transmission and applying clamping force.

[0091] Alternatively, as Figure 8 As shown, the worm wheel 623 and the worm 621 are disposed inside the clamping frame 31 of the clamping seat 30. The worm wheel 623 is meshed with the worm 621 and sleeved on the second transmission rod 624. When the worm 621 rotates, the worm wheel 623 rotates under the meshing action, driving the second transmission rod 624 to rotate.

[0092] Further, if Figure 9 As shown, a half-tooth gear 625 is sleeved on the second transmission rod 624. Figure 7 As shown, the half-toothed gear 625 is engaged with the second rack 626. The second transmission rod 624, the half-toothed gear 625 and the second rack 626 are disposed inside the clamping frame 31 of the clamping seat 30.

[0093] The rotation of the second transmission rod 624 drives the half-toothed gear 625, which meshes with the second rack 626 to move in the third direction. The number of teeth meshing between the half-toothed gear 625 and the second rack 626 determines the range of movement of the second rack 626. Optionally, in this embodiment, the range of movement of the second rack 626 is no greater than the size of the clamping space in the third direction.

[0094] Furthermore, the clamping mechanism 63 is fixedly connected to a second rack 626 and disposed within the clamping frame 31. When the adjustment mechanism 61 rotates on the support rod 20, the second rack 626 drives the clamping mechanism 63 into the clamping space. Specifically, in this embodiment, when the second sleeve 611 rotates relative to the lower support rod 21 and the upper support rod 22, the universal joint 622 drives the worm 621, the worm gear 623, the second transmission rod 624, the half-tooth gear 625, and the second rack 626 in sequence, thereby achieving movement of the clamping mechanism 63 in the third direction.

[0095] like Figure 8 As shown, the clamping mechanism 63 includes a support frame 631 , a movable plate 632 , a guide rod 633 , a clamping block 634 and a second elastic member 635 .

[0096] In this embodiment, the support frame 631 is configured as a U-shaped frame with an opening along the third direction toward the clamping space. The support frame 631 is slidably mounted on the clamping seat 30 and affixed to the transmission mechanism 62. Specifically, the support frame 631 is slidably mounted within the clamping frame 31 and affixed to the second rack 626.

[0097] The movable plate 632 is rotatably mounted on the clamping seat 30. Optionally, the movable plate 632 is rotatably connected to a rotating shaft, the other end of which is fixedly connected to the clamping frame 31 of the clamping seat 30. The movable plate 632 rotates relative to the clamping frame 31 under the action of the rotating shaft.

[0098] One end of the guide rod 633 is fixedly connected to the clamping block 634 and the other end is movably arranged. In this embodiment, the guide rod 633 is slidably arranged inside the clamping frame 31 of the clamping seat 30 along the third direction and is surrounded by the support frame 631.

[0099] Furthermore, a first notch is provided on each side of the guide rod 633, and a second notch is provided on the inner side of the support frame 631, with the first notch corresponding to the second notch. A movable plate 632 is sandwiched between each corresponding first notch and second notch. The ends of the movable plate 632 abut and are respectively located within the first and second notches, thereby movably connecting the guide rod 633 and the support frame 631, achieving a sliding connection between the guide rod 633.

[0100] like Figure 8 As shown, when the second rack 626 of the transmission mechanism 62 drives the support frame 631 away from the clamping space, the guide rod 633, driven by the movable plate 632, drives the clamping block 634 into the clamping space. When the second rack 626 of the transmission mechanism 62 drives the support frame 631 toward the clamping space, the guide rod 633, driven by the movable plate 632, drives the clamping block 634 out of the clamping space.

[0101] Specifically, driven by the support frame 631, the movable plate 632 rotates under the abutment of the second slot wall and the action of the rotating shaft, so that the guide rod 633 and the support frame 631 move in opposite directions, further realizing the control of the position of the clamping block 634, and completing the clamping and loosening of the melting tube in the clamping space.

[0102] In this embodiment, the clamping block 634 is provided with an arcuate surface at one end facing the clamping space. The arcuate surface can better fit the surface of the melting tube, press the melting tube against the clamping plate 32, apply a clamping force to it, and prevent the melting tube from falling off during transportation.

[0103] Furthermore, a second elastic member 635 is disposed between the support frame 631 and the clamping seat 30. This second elastic member 635 is configured as a spring, but other elastically contractible structures may also be employed. The ends of the spring are respectively secured to the inner walls of the support frame 631 and the clamping frame 31. When the support frame 631 moves in the third direction, the spring applies tension and thrust to it, facilitating its return to its original state and achieving automatic restoration of the device.

[0104] Example 2

[0105] This embodiment provides a cable fixing device, wherein the components identical or corresponding to those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For simplicity, only the differences between the second embodiment and the first embodiment are described. The differences are:

[0106] like Figure 3 and Figure 7 As shown, the ends of the universal joint 622 are connected to the worm 621 and the extension rod, respectively. The other end of the extension rod is fixed to the partition of the second sleeve 611 of the adjustment mechanism 61. When the second sleeve 611 rotates relative to the lower support rod 21 and the upper support rod 22, the extension rod rotates accordingly, and drives the worm 621 through the universal joint 622. The provision of the extension rod facilitates increasing the overall height of the device, allowing the clamping seat 30 to be more closely positioned to the melting pipe, eliminating the need for additional climbing equipment and reducing the risk of personnel climbing. The length of the extension rod can be adjusted as needed and will not be further described here.
