Description

Technical Field

[0001] This utility model relates to the field of power system maintenance, specifically to a high-voltage insulating operating rod. Background Technology

[0002] Insulated operating rods are widely used in the maintenance and operation of power systems, especially in the operation of high-voltage equipment of 10kV, 35kV and above, to isolate high voltage and ensure personal safety. These tools typically consist of an insulated rod body and an operating head, allowing the operator to perform remote pulling, opening, disassembly, and assembly operations by controlling the end of the rod.

[0003] Existing insulated operating rods are mostly multi-section threaded connections or telescopic sleeve structures, primarily used for remote operation of high-voltage power equipment. Multi-section structures require individual tightening before operation, making assembly cumbersome; while telescopic structures facilitate length adjustment, the rod body is typically "thinner at the front and thicker at the back," with the thinner end being more flexible and prone to bending during operation, affecting stability. Furthermore, these structures generally lack angle adjustment functionality, making it difficult for operators to adjust the operating angle in space-constrained or complex equipment layout scenarios, resulting in inconvenience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a high-voltage insulating operating rod, which aims to alleviate the above problems to at least a certain extent.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-voltage insulating operating rod, comprising: The main body of the control lever includes three insulating rods: a head rod, a middle rod, and a tail rod. The end of the tail rod is provided with a control lever head. The first rod and the middle rod, as well as the middle rod and the tail rod, are all hinged together by a connecting part, which is used to realize the rotatable connection between adjacent insulating rods; The middle rod can rotate relative to the first rod around the connecting part, and the tail rod can rotate relative to the middle rod around the connecting part; The connecting part is equipped with a locking mechanism for positioning and fixing the insulating rod after it has been rotated to a predetermined angle.

[0006] Preferably, the connecting part includes a support bar fixed to the first rod and the middle rod, the middle rod is rotatably connected to the support bar on the first rod, the tail rod is rotatably connected to the support bar on the middle rod, a plurality of positioning shafts are slidably connected to the support bar, and the middle rod and the tail rod are provided with positioning holes that slidably cooperate with the positioning shafts, and the positioning shafts slidably cooperate with the positioning holes.

[0007] Preferably, a connecting frame is slidably connected to the support bar, a plurality of positioning shafts are fixed on the connecting frame, and a spring a is connected between the connecting frame and the support bar.

[0008] Preferably, a push plate is slidably connected to the first rod and the middle rod, and a wedge-shaped strip is connected to the connecting frame.

[0009] Preferably, the end of the tail rod is rotatably connected to a connector, and the control lever head is fixed to the connector.

[0010] Preferably, the connector head is slidably connected with multiple push rods, and the inner wall of the tail rod is provided with multiple top grooves that cooperate with the push rods. The top grooves are hemispherical grooves, and a spring b is connected between the push rods and the connector head.

[0011] In summary, the present invention has the following main advantages: This invention utilizes a multi-segment hinged structure consisting of a head rod, middle rod, and tail rod, allowing for flexible angle adjustment to suit various working environments. Connecting sections between segments, along with push plates, wedge-shaped strips, and multiple positioning shafts, form a three-dimensional locking mechanism. This enables rapid, multi-point synchronous locking, ensuring structural stability and strong torsional rigidity. Compared to traditional push-type structures, the push plate operates by sliding along the rod's direction, preventing accidental activation and improving operational safety in confined spaces.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] refer to Figures 1-7 This embodiment provides a high-voltage insulated operating rod, including an operating rod body 100. The operating rod body 100 is composed of three insulating rods: a head rod 101, a middle rod 102, and a tail rod 103. The three insulating rods are connected in sequence. The end of the tail rod 103 is provided with an operating rod head 104 for applying force.

[0016] The first rod 101 and the middle rod 102, as well as the middle rod 102 and the tail rod 103, are hinged together by a connecting part 105 of the same structure. This connecting part 105 enables a rotatable connection between adjacent insulating rods. During use, the middle rod 102 can rotate relative to the first rod 101 around the connecting part 105 between it and the first rod 101, and the tail rod 103 can also rotate relative to the middle rod 102 around the connecting part 105 between it and the middle rod 102. This structure allows the entire operating rod to be adjusted to multiple angles according to on-site requirements, improving operational flexibility and adaptability.

[0017] To prevent the rod sections from loosening or shifting due to angle changes during use, each connecting part 105 is equipped with a locking mechanism. This locking mechanism is used to position and fix the insulating rod after it has been rotated to a predetermined angle, thereby ensuring that the operating rod has a stable structural form at a specific angle.

[0018] With the above settings, in actual use, the operator holds the end of the first lever 101 and applies operating force by manipulating the first lever 101 to remotely control the opening, closing, and tossing of the high-voltage equipment.

[0019] The operator can pre-adjust the angle of the main body 100 of the operating lever according to the spatial structure and operational requirements of the site. Specifically, the operator can rotate the middle lever 102 relative to the connection 105 between it and the first lever 101. Similarly, the tail lever 103 can also rotate relative to the connection 105 between it and the middle lever 102. The two connection parts 105 mentioned above have the same structure and are both rotatable connection structures, which have flexible rotation capabilities and can make the operating lever form a certain angle between each segment, thereby creating a spatial posture suitable for different working environments.

[0020] Once the middle lever 102 or the tail lever 103 has rotated to the desired angle, the operator can lock it using the locking mechanism provided in each connecting part 105. The locking mechanism can quickly position and fix the current state after rotating to the preset angle, preventing displacement during operation. Through this angle adjustment and locking mechanism, good structural stability can be ensured even when the entire operating lever is not in a straight-line extended state.

[0021] After adjustment, the main body 100 of the operating rod connects sequentially from the end of the first rod 101 to the middle rod 102 and the tail rod 103, forming an extended structure composed of multiple rotating hinge segments. Compared with traditional linear insulated operating rods, this device creates a natural avoidance zone in the middle section through angular deflection, possessing a certain spatial misalignment characteristic. This characteristic allows the device to bypass power equipment, conductor connectors 300, or other spatial obstacles, exhibiting stronger accessibility and adaptability in narrow and complex power operation environments.

[0022] During operation, the operator grips and applies force from the end of the first lever 101. The force is transmitted sequentially to the tail end via the locked middle lever 102 and tail lever 103. The control lever head 104 at the end of the tail lever 103 contacts and completes the control action on the target equipment. Since both the middle lever 102 and the tail lever 103 are fixed at their angles through locking mechanisms, the entire force transmission path is stable and reliable. No lever swaying or angle deviation will occur during operation, further improving the safety and control accuracy of the operation.

[0023] In this embodiment, a connecting portion 105 with the same structure is provided between the first rod 101 and the middle rod 102, and between the middle rod 102 and the tail rod 103. The connecting portion 105 includes a support bar 200 fixedly disposed between the first rod 101 and the middle rod 102. The middle rod 102 is rotatably connected to the support bar 200 on the first rod 101 via a rotating shaft. Similarly, the tail rod 103 is also rotatably connected to the support bar 200 on the middle rod 102 via a rotating shaft, so that both the middle rod 102 and the tail rod 103 can rotate relative to the preceding rod segment around the support bar 200.

[0024] To achieve angle locking, multiple positioning shafts 201 are slidably connected to the support bar 200. Positioning ports 202 are respectively provided on the middle rod 102 and the tail rod 103. The positioning shafts 201 can be slidably inserted into the corresponding positioning ports 202, achieving mechanical limiting and position fixing of each rod segment at a predetermined angle. The positioning shafts 201 and the positioning ports 202 have a sliding fit structure, ensuring a quick and reliable locking process and facilitating rapid on-site deployment.

[0025] With the above settings, in actual use, the operator holds the end of the first rod 101 and adjusts the rotation angle of the middle rod 102 and the tail rod 103 to adapt to different working spaces and operating directions.

[0026] The middle rod 102 is rotatably connected to the first rod 101 via a support bar 200 structure, and can change angles around the axis of rotation; the tail rod 103 rotates relative to the middle rod 102 via the support bar 200 structure between it and the middle rod 102.

[0027] The support bar 200 provides a stable hinge point, ensuring good structural rigidity of the lever during angle adjustment. When angle locking is required, the operator pushes the positioning shaft 201 on the support bar 200, causing it to slide and insert into the corresponding positioning port 202. The positioning shaft 201 and the positioning port 202 have a precise sliding fit structure, which locks the current angle after insertion, preventing accidental deflection of the lever during use. This structure gives the entire operating lever excellent angle-holding capability after angle adjustment, significantly improving operational stability and safety.

[0028] Furthermore, since the positioning shaft 201 can slide along the support bar 200 to multiple positions and is used in conjunction with multiple positioning ports 202, it can support multiple angle adjustments, enhancing the adaptability of this device in complex spaces. Operators can flexibly select the angle configuration according to different site conditions, improving the efficiency and accuracy of actual operation.

[0029] Furthermore, based on the above embodiments, in order to improve the overall strength and ease of operation of the angle locking, a connecting frame 203 is slidably connected to the support bar 200, and multiple positioning shafts 201 are fixedly installed on the connecting frame 203. A spring a204 is connected between the connecting frame 203 and the support bar 200.

[0030] The connecting frame 203 can slide relative to the support bar 200 along the length direction, thereby driving multiple positioning shafts 201 to move synchronously as a whole; the spring a204 is disposed between the connecting frame 203 and the support bar 200, and is used to reset the connecting frame 203 to the initial position when no external force is applied.

[0031] With the above setup, in actual use, the operator first adjusts the unfolding angle of the operating lever, causing the middle lever 102 or the tail lever 103 to rotate around its corresponding support bar 200 to the target angle. Because the connecting part 105 is equipped with the support bar 200, the rotating structure can be flexibly unfolded within the structural limits, adapting to various complex working spaces.

[0032] After the angle adjustment is completed, the operator pushes the connecting frame 203 set on the support bar 200. During the sliding process, the connecting frame 203 drives the multiple positioning shafts 201 fixed on it to move synchronously. When the axis of the positioning shaft 201 is aligned with the positioning port 202 on the middle rod 102 or the tail rod 103, the positioning shaft 201 is inserted into the positioning port 202 as a whole, realizing multi-point limiting and fixing. This synchronous insertion structure avoids the inconvenience of inserting and removing multiple positioning points one by one in the traditional method, and significantly improves the adjustment efficiency.

[0033] After positioning is completed, the external force is released, and spring a204 pulls the connecting bracket 203 back, keeping the positioning shaft 201 in the inserted state, thus completing the locking. Since multiple positioning shafts 201 are distributed at the connection position, forming multiple force points, the overall structure exhibits higher torsional rigidity and stability after locking. It is not easy for the rod to wobble or loosen under external force operation or electric field disturbance, which significantly improves the stability of the operating rod.

[0034] Furthermore, in this embodiment, push plates 205 for driving the locking mechanism are slidably connected to both the first rod 101 and the middle rod 102, and wedge-shaped strips 206 are fixedly connected to the connecting frame 203.

[0035] The pusher 205 is a long strip structure that can slide along the axial direction of the first rod 101 and the middle rod 102. Its front end is provided with a contact end for contacting the inclined surface of the wedge strip 206. The wedge strip 206 is a rigid component with a wedge angle, fixed on the connecting frame 203, and its inclined surface faces the front end of the pusher 205 to form an inclined surface contact relationship.

[0036] In the assembled state, during the sliding process of the push plate 205, its front end will press against the inclined surface of the wedge strip 206, causing the wedge strip 206 and the connected frame 203 to undergo lateral displacement, thereby driving the connecting frame 203 to move as a whole, and thus realizing the linkage control of multiple positioning axes 201.

[0037] This structure achieves the force transmission conversion from axial pushing to lateral locking by setting a simple sliding push plate 205 and wedge-shaped inclined surface conversion relationship. The structure is compact and responds quickly, which facilitates rapid, one-handed operation and improves the practicality and convenience of the insulated operating rod in the field for efficient deployment and locking process.

[0038] Furthermore, compared with the common press-type locking and release structure in the prior art, this application demonstrates significant differences and practical advantages in terms of operation, triggering path, safety, and usable space by setting an inclined linkage structure between the sliding push plate 205 and the wedge strip 206.

[0039] Specifically, traditional push-button structures typically require vertical pressing to trigger, and the button surface is exposed, making them susceptible to accidental activation due to collisions with surrounding objects or accidental hand contact. This is especially problematic in environments with dense equipment or confined spaces, posing a risk of misoperation. In contrast, the pusher 205 structure in this application requires sliding along the axis of the rod, providing a clear directional triggering action and naturally avoiding interference from lateral obstacles such as cables, guide rails, and protective covers.

[0040] In addition, the inclined surface cooperation between the push plate 205 and the wedge strip 206 can not only convert the axial thrust into the lateral driving force of the connecting frame 203 and realize the synchronous insertion of multiple positioning shafts 201, but also provide stable locking feedback through structural cooperation, avoiding the problem of accidental contact that is difficult to detect.

[0041] In this embodiment, the end of the tail rod 103 is rotatably connected to a connector 300, and the control lever head 104 is fixedly mounted on the connector 300.

[0042] The tail rod 103 and the connector 300 are rotatably connected via a pivot, allowing the connector 300 to rotate within a certain angle range around the pivot. The connector 300 is a rigid structure, with one end rotatably engaged with the tail rod 103 and the other end fixedly mounted with the control lever head 104, allowing the control lever head 104 to be adjusted in angle with the connector 300.

[0043] With the above setup, in actual operation, the operator applies operating force through the first lever 101, and the force is transmitted sequentially to the control lever head 104 at the tail end via the middle lever 102 and the tail lever 103.

[0044] Because the tail rod 103 has a connector 300 at its end, the control lever head 104 is not rigidly fixed to the end of the tail rod 103. Instead, it is rotatably connected to the tail rod 103 via the connector 300. This allows the angle of the control lever head 104 to be pre-adjusted according to operational requirements before operation, ensuring better alignment and docking with the target equipment. This structure is particularly suitable for situations where the angle of the operated object is not fixed or there are installation deviations. It improves the contact efficiency between the control head and the controlled component, reducing problems such as misalignment, slippage, or poor contact caused by angle mismatch.

[0045] In this embodiment, in order to ensure that the control lever head 104 can be reliably positioned and prevent shaking after the angle is adjusted, a plurality of push rods 301 are slidably connected to the connector 300, and a plurality of top grooves 302 that cooperate with the push rods 301 are provided on the inner wall of the tail rod 103.

[0046] The top groove 302 is a hemispherical groove, spaced apart along the circumferential direction of the inner wall of the tail rod 103; the top rod 301 is elastically connected to the inside of the connector 300 by a spring b303 and can slide in the axial direction. When the connector 300 rotates around its axis, the top rod 301 continuously pushes outward under the action of the spring b303. When the top rod 301 slides to the position aligned with the top groove 302, it automatically springs into the hemispherical top groove 302, forming a stable angular positioning state.

[0047] With the above settings, before actual operation, the operator can adjust the angle of the control lever head 104 through the connector 300 according to the position and direction of the controlled electrical equipment. While the connector 300 rotates around the pivot relative to the tail rod 103, multiple push rods 301 continuously press outward against the inner wall of the tail rod 103 under the elastic force of the spring b303.

[0048] As the connector 300 rotates, the push rod 301 slides into contact with the inner wall of the tail rod 103 and gradually aligns with the multiple hemispherical top grooves 302 thereon. When the push rod 301 moves to align with any top groove 302, under the action of the spring b303, the push rod 301 will automatically spring into the top groove 302, thereby achieving reliable positioning of the current angle position. At this time, the connector 300 has obvious mechanical damping and positioning holding force at this angle, which can prevent angle deviation caused by shaking, vibration or slight accidental contact.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
