Description

Technical Field

[0001] This utility model relates to the field of insulating rod technology, and in particular to an insulating rod structure. Background Technology

[0002] In power generation, insulating rods are commonly used for switching operations and maintenance. As a basic safety tool for live-line work, the function of insulating rods is to establish an insulating layer between the operator and the live conductor, preventing electric shock accidents caused by contact with or proximity to high-voltage live conductors.

[0003] Currently, insulating rods consist of a working head, insulating sections, and a handle. The working head is located at the top of the insulating rod and is used to connect tools such as hooks, chucks, or pin pullers. The handle is located at the end of the insulating rod for the operator to hold. Insulating rods are usually composed of multiple sections, which are fixedly connected by threaded joints to extend the effective insulation distance between high-voltage live parts and the human body.

[0004] However, when operating drop-out circuit breakers using insulating rods, the threaded connections of the insulating rods may not be tightened reliably, and various parts of the insulating rod may rotate, resulting in poor safety and stability during live-line work. Utility Model Content

[0005] The technical problem this invention aims to solve is that the threaded connection of existing insulating rods is unreliable, and various parts of the insulating rod may rotate, resulting in poor safety and stability during live-line work.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for an insulating rod structure: The insulating rod structure includes a first rod body, a second rod body, and an anti-rotation structure. The end of the first rod body is provided with an external threaded joint, and the end of the second rod body is provided with an internal threaded interface. The external threaded joint is threadedly connected to the internal threaded interface. The first rod body has a first guide portion on the outer side of its end, and the second rod body has a second guide portion on the outer side of its end. Both the first guide portion and the second guide portion extend along the axial direction of the first rod body. The anti-rotation structure includes an anti-rotation sleeve and an operating component. The anti-rotation sleeve and the operating component are both slidably installed on the outer side of the end of the first rod body, and the operating component is connected to the anti-rotation sleeve along the axial direction of the first rod body. Along the axial direction of the first rod, the anti-rotation sleeve is guided and engaged with the first guide portion and the second guide portion respectively; along the circumferential direction of the first rod, the anti-rotation sleeve is limited and engaged with the first guide portion and the second guide portion respectively.

[0007] Furthermore, the first guide portion is a first protrusion, the second guide portion is a second protrusion, and the inner wall of the anti-rotation sleeve is provided with a groove, which slides in cooperation with the first protrusion and the second protrusion along the axial direction of the first rod body.

[0008] Furthermore, there are multiple first protrusions, which are circumferentially spaced around the outer side of the end of the first rod. There are also multiple second protrusions, which are circumferentially spaced around the outer side of the end of the second rod. When the first rod and the second rod are threaded together, the multiple first protrusions and the multiple second protrusions are arranged in a one-to-one correspondence.

[0009] Furthermore, the inner wall of the anti-rotation sleeve is provided with a plurality of grooves spaced apart in a circumferential direction, and the plurality of grooves are arranged in a one-to-one correspondence with the plurality of first protrusions.

[0010] Furthermore, the anti-rotation structure also includes an outer shell, which is fitted and fixed to the outer side of the end of the first rod. An annular gap is formed between the outer shell and the first rod. The anti-rotation sleeve and the operating member are slidably installed in the annular gap, and the operating member is located on the side of the anti-rotation sleeve away from the second rod.

[0011] Furthermore, the operating component is a spring-type operating component, which elastically presses against the outer shell and the first rod respectively. The operating component is also provided with a protrusion, and the outer shell has an elongated groove. The protrusion slides with the elongated groove along the axial direction of the first rod, and the protrusion protrudes from the outside of the elongated groove.

[0012] Furthermore, a groove is provided on the outer side of the first rod near the first guide portion, the groove extending along the axial direction of the first rod, and the operating member is slidably installed in the groove.

[0013] Furthermore, there are two operating components, which are symmetrically distributed about the central axis of the first rod.

[0014] Compared with existing technologies, the insulating rod structure of this utility model has the following advantages: The insulating rod structure adopts a design of a first rod body, a second rod body, and an anti-rotation structure. The first and second rod bodies are threaded together via an external threaded connector and an internal threaded interface. A first guide portion is provided on the outer side of the end of the first rod body, and a second guide portion is provided on the outer side of the end of the second rod body. Both guide portions extend along the axial direction of the first rod body. An anti-rotation sleeve is slidably installed on the outer side of the end of the first rod body. The anti-rotation sleeve guides and cooperates with the first and second guide portions respectively, and is in an upper limit fit with the first and second guide portions in the circumferential direction. When the anti-rotation sleeve slides to the position covering the two guide portions, it rigidly prevents the first and second rod bodies from rotating relative to each other, effectively preventing the threaded connection from loosening.

[0015] The operating component and the anti-rotation sleeve are connected along the axis of the first rod. Simply pushing or pulling the operating component axially moves the anti-rotation sleeve, switching it between locked and unlocked states with the second guide portion. No additional tools are required, facilitating quick locking and unlocking operations. Furthermore, the axial movement of the anti-rotation sleeve, guided and engaged with the first and second guide portions, prevents it from tilting or jamming during sliding, ensuring precise adjustment to the locked position. The anti-rotation sleeve is slidably installed on the outer end of the first rod, effectively forming a clamp at the threaded connection of the two rods. Without increasing the complexity of the rod structure, this improves the joint rigidity of the entire insulating rod, thus ensuring the safety and stability of live-line work.

[0021] like Figures 1 to 3 As shown, an insulating rod structure according to an embodiment of the present invention includes a first rod body 1, a second rod body 2, and an anti-rotation structure 3. The end of the first rod body 1 is provided with an external threaded connector 10, and the end of the second rod body 2 is provided with an internal threaded interface 20. The external threaded connector 10 and the internal threaded interface 20 are threadedly connected. The outer side of the end of the first rod body 1 is provided with a first guide portion 11, and the outer side of the end of the second rod body 2 is provided with a second guide portion 21. Both the first guide portion 11 and the second guide portion 21 extend along the axial direction of the first rod body 1.

[0022] The anti-rotation structure 3 includes an anti-rotation sleeve 31 and an operating member 32. The anti-rotation sleeve 31 and the operating member 32 are slidably installed on the outer side of the end of the first rod 1, and the operating member 32 is connected to the anti-rotation sleeve 31 along the axial direction of the first rod 1. Along the axial direction of the first rod 1, the anti-rotation sleeve 31 is guided and engaged with the first guide part 11 and the second guide part 21 respectively. Along the circumferential direction of the first rod 1, the anti-rotation sleeve 31 is limited and engaged with the first guide part 11 and the second guide part 21 respectively.

[0023] The insulating rod structure adopts a design of a first rod 1, a second rod 2, and an anti-rotation structure 3. The first rod 1 and the second rod 2 are connected by an external threaded connector 10 and an internal threaded interface 20. The outer side of the end of the first rod 1 is provided with a first guide part 11, and the outer side of the end of the second rod 2 is provided with a second guide part 21. Both guide parts extend along the axial direction of the first rod 1. The anti-rotation sleeve 31 is slidably installed on the outer side of the end of the first rod 1.

[0024] Furthermore, the anti-rotation sleeve 31 is guided and engaged with the first guide part 11 and the second guide part 21 respectively. The anti-rotation sleeve 31 is engaged with the first guide part 11 and the second guide part 21 in the circumferential direction. When the anti-rotation sleeve 31 slides to the position covering the two guide parts, the anti-rotation sleeve 31 can rigidly prevent the first rod body 1 and the second rod body 2 from rotating relative to each other, which effectively prevents the threaded connection from loosening.

[0025] The operating member 32 is connected to the anti-rotation sleeve 31 along the axial direction of the first rod body 1. Only by pushing or pulling the operating member 32 in the axial direction can the anti-rotation sleeve 31 be moved axially, so that the anti-rotation sleeve 31 and the second guide part 21 can switch between the state of engagement and locking or disengagement and unlocking. No additional tools are required, which makes it easy to quickly complete the locking and unlocking operations.

[0026] Furthermore, the anti-rotation sleeve 31 moves axially and engages with the first guide portion 11 and the second guide portion 21, preventing the anti-rotation sleeve 31 from tilting or jamming during sliding and ensuring precise adjustment to the locked position. The anti-rotation sleeve 31 is slidably installed on the outer side of the end of the first rod 1, which is equivalent to forming a clamp at the threaded connection of the two rods. Without increasing the complexity of the rod structure, it improves the node rigidity of the entire insulating rod, thereby ensuring the safety and stability of live-line work.

[0027] In this embodiment, the first guide portion 11 is a first protrusion 110, the second guide portion 21 is a second protrusion 210, and the inner wall of the anti-rotation sleeve 31 is provided with a groove 310. The groove 310 slides and engages with the first protrusion 110 and the second protrusion 210 along the axial direction of the first rod 1. Specifically, there are multiple first protrusions 110, which are circumferentially spaced around the outer side of the end of the first rod 1. There are also multiple second protrusions 210, which are circumferentially spaced around the outer side of the end of the second rod 2. When the first rod 1 and the second rod 2 are threadedly connected in place, the multiple first protrusions 110 and the multiple second protrusions 210 are arranged in a one-to-one correspondence.

[0028] Furthermore, the inner wall of the anti-rotation sleeve 31 is circumferentially provided with multiple grooves 310, each groove 310 corresponding to a number of first protrusions 110. When the first rod 1 and the second rod 2 are threadedly connected, the anti-rotation sleeve 31 initially remains in a position away from the external threaded joint 10, and the grooves 310 of the anti-rotation sleeve 31 are not engaged with the second protrusions 210 of the second rod 2, ensuring that the two rods can be smoothly threadedly connected. When the two rods are threadedly connected in place, the first protrusions 110 and the second protrusions 210 are axially aligned, and the grooves 310 of the anti-rotation sleeve 31 simultaneously engage with the first protrusions 110 and the second protrusions 210, preventing the connection between the two rods from becoming loose.

[0029] As a further preferred embodiment, the anti-rotation structure 3 also includes an outer shell 33, which is fitted and fixed to the outer side of the end of the first rod 1. An annular gap 30 is formed between the outer shell 33 and the first rod 1. The anti-rotation sleeve 31 and the operating member 32 are slidably installed in the annular gap 30, with the operating member 32 located on the side of the anti-rotation sleeve 31 away from the second rod 2. The outer shell 33 provides shielding and protection for the anti-rotation sleeve 31 and the operating member 32, ensuring the reliable stability of the anti-rotation structure 3.

[0030] like Figure 3 As shown, the operating component 32 is a spring-loaded operating component. The operating component 32 elastically presses against the outer shell 33 and the first rod 1, respectively. Friction is generated between the spring-loaded operating component, the outer shell 33, and the first rod 1, preventing the anti-rotation sleeve 31 from accidentally unlocking due to gravity sliding. The operating component 32 also has a protrusion 320, and the outer shell 33 has an elongated groove 330. The protrusion 320 and the elongated groove 330 slide along the axial direction of the first rod 1, and the protrusion 320 protrudes from the outer side of the elongated groove 330. The operator manually pushes or pulls the protrusion 320 of the operating component 32, causing the operating component 32 to move along the length of the elongated groove 330, thus completing the flexible locking and unlocking switching operation.

[0031] In addition, a groove 34 is provided on the outer side of the first rod 1 near the first guide portion 11. The groove 34 extends along the axial direction of the first rod 1. The operating member 32 is slidably installed in the groove 34. The groove 34 provides a more reliable movement path for the operating member 32, preventing the operating member 32 from deviating and affecting the normal adjustment of the anti-rotation sleeve 31. There are two operating members 32, which are symmetrically distributed about the central axis of the first rod 1. The symmetrical structural design of the two operating members 32 improves the stability of the axial movement of the anti-rotation sleeve 31 and avoids the jamming problem that easily occurs when pushing and pulling the anti-rotation sleeve 31 at a single point.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
