Description

Technical Field

[0001] This invention belongs to the field of power auxiliary tool technology, and more specifically, relates to an insulated operating rod quick-release head and an insulated operating rod. Background Technology

[0002] Insulated operating rods are essential safety tools in power systems for live-line work, inspection, and maintenance. They are designed to provide safe electrical isolation in high-voltage environments, allowing workers to operate while the circuit is energized without the risk of electric shock.

[0003] Currently, common insulated operating rods typically consist of three parts: a working head, an insulating rod, and a handle. When performing substation maintenance and repair work, operators need to use different specifications and types of working heads depending on the work being done. When working outdoors, workers often carry multiple different types of working heads for interchange. In practice, the working head and insulating rod are mostly detachably connected via threads. To maintain the connection strength, the thread length on both the working head and insulating rod is designed to be relatively long, resulting in a longer installation time and poor adaptability to some emergency applications. Furthermore, in practical applications, the working head often needs to be rotated by turning the insulating rod. With repeated use, thread wear can cause the insulating rod to rotate relative to the working head during rotation, leading to the working head and insulating rod becoming loose. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-connect head and an insulating operating rod, which aims to solve the problems of slow connection speed and easy loosening of the insulating rod and the working head in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A quick-release head for an insulating operating rod is provided, comprising a first connector and a second connector that are fitted together. The first connector is mounted on a working head, and the second connector is mounted on an insulating rod. A first slot is provided at the lower center of the first connector. A first groove is provided on the side wall of the first slot, extending longitudinally downward through the lower end face of the first connector. A connecting clip is provided longitudinally at the bottom of the first slot. A locking component is provided at the upper end of the second connector corresponding to the connecting clip. A first locking block is provided longitudinally on the side wall of the second connector. In use, the second connector is inserted into the first slot, and the first locking block is inserted into the first groove to restrict relative rotation between the first connector and the second connector. The connecting clip and the locking component are fitted together to restrict axial movement of the first connector relative to the second connector.

[0006] In one possible implementation, the upper end face of the first connector is provided with a first connecting groove, and the working head is inserted into the first connecting groove; the lower end face of the second connector is provided with a second connecting groove, and the insulating rod is inserted into the second connecting groove.

[0007] In one possible implementation, the connecting clip includes a connecting rod with a threaded section. The upper end face of the second connector has a first mounting groove. The locking assembly is disposed in the first mounting groove. The locking assembly includes a fixing block, a locking sleeve, and a driving part. The fixing block is inserted into the first mounting groove. The middle part of the fixing block has a second mounting groove. The locking sleeve is rotatably disposed in the second mounting groove. The middle part of the locking sleeve has a threaded hole that mates with the threaded section. The upper end of the fixing block has a first clearance hole communicating with the second mounting groove. The first clearance hole and the threaded hole are coaxially arranged. In use, the driving part drives the locking sleeve to rotate, and the threaded section passes through the first clearance hole and is threadedly connected in the threaded hole.

[0008] In one possible implementation, the lower end of the fixing block is provided with a third mounting groove, which is located on one side of the second mounting groove. The second mounting groove and the third mounting groove are connected by a longitudinal groove. The side wall of the locking sleeve is provided with a first sliding groove, which spirally surrounds the outer half of the locking sleeve from top to bottom. The driving part includes a first slider and a driving plate. The first slider is slidably connected to the third mounting groove. A crossbar is provided on the side of the first slider facing the longitudinal groove. The crossbar passes through the longitudinal groove and is inserted into the first sliding groove. The movable plate is slidably disposed in the first mounting groove and located below the fixed block. The first slider and the drive plate are connected by a longitudinal rod. The connecting rod is provided with an abutment section. The diameter of the abutment section is smaller than the diameter of the threaded section. The abutment section is connected to the lower end of the threaded section. The lower end of the fixed block is provided with a second clearance hole that communicates with the second mounting groove. In use, the abutment section passes through the second clearance hole and presses against the drive plate to move downward, driving the first slider and the crossbar to move downward, so that the end of the crossbar slides from the upper end to the lower end of the groove to drive the locking sleeve to rotate.

[0009] In one possible implementation, a first spring is provided between the bottom surface of the first mounting slot and the drive plate.

[0010] In one possible implementation, the upper end of the threaded hole is connected to a guide hole, and the inner wall of the guide hole is inclined inward from top to bottom.

[0011] In one possible implementation, a second slot is provided longitudinally on the side wall of the second connector, and the first slot is connected to the second slot on the side facing the second connector. The second slot is inserted into the second slot and slidably connected to the second slot. The second slot slides up and down in the second slot to allow the first slot to engage or disengage with the first slot.

[0012] In one possible implementation, a movable sleeve is slidably fitted onto the second connector, and the first locking block is connected to the movable sleeve.

[0013] In one possible implementation, the side wall of the second connector is circumferentially surrounded by an annular stop block, the annular stop block being located below the movable sleeve, and a second spring is also threaded through the second connector, the second spring being connected between the movable sleeve and the annular stop block.

[0014] The beneficial effects of the quick-connect and disconnect head for an insulating operating rod provided by the present invention are as follows: Compared with the prior art, the quick-connect and disconnect head for an insulating operating rod of the present invention, when in use, inserts the second connector into the first slot, so that the first locking block is inserted into the first slot to restrict the relative rotation of the first connector and the second connector, and the connecting clip is inserted and engaged with the locking component, so that the locking component locks the connecting clip to restrict the longitudinal movement of the first connector relative to the second connector. The quick-connect and disconnect head for an insulating operating rod provided by the present invention has a fast connection speed, and by simultaneously restricting the relative rotation and relative longitudinal movement of the first connector and the second connector, the connection strength between the first connector and the second connector is strong and not easy to loosen.

[0015] The invention also provides an insulated operating rod, including an insulated rod and a working head, wherein the insulated rod and the working head are connected by the aforementioned insulated operating rod quick-release head.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] Please see Figures 1 to 4 The present invention will now describe a quick-release head for an insulating operating rod and an insulating operating rod. The quick-release head for an insulating operating rod includes a first connector 1 and a second connector 2 that fit together. In practical applications, the first connector 1 is fixedly mounted on a working head, and the second connector 2 is fixedly mounted on an insulating rod. A first slot 101 is provided at the lower center of the first connector 1, which is adapted to the upper end of the second connector 2. A first groove 103 is provided on the side wall of the first slot 101, extending longitudinally downward through the lower end face of the first connector 1. In this embodiment, the first groove 103 extends radially through the side wall of the first connector 1. This arrangement facilitates the processing of the first groove 103. A connecting clip is provided longitudinally at the center of the bottom of the first slot 101. The connector is fixedly connected to the first connector 1. Preferably, the connector and the first connector 1 are integrally formed. By making the connector and the connector integrally formed, the connection between the connector and the first connector 1 can be made more stable. A locking component is provided at the upper end of the second connector 2 corresponding to the connector. A first locking block 21 is provided longitudinally on the side wall of the second connector 2. In use, the second connector 2 is inserted into the first slot 101, and the first locking block 21 is inserted into the first slot 103 to restrict the relative rotation of the first connector 1 and the second connector 2. The connector and the locking component are inserted and cooperated. The locking component locks the connector to restrict the axial movement of the first connector 1 relative to the second connector 2.

[0022] In this embodiment, in order to improve the connection effect, the number of first slots 103 is set to two, but not limited to two, so that the two first slots 103 are symmetrically arranged on the side wall of the first connector 1. Similarly, the number of first blocks 21 corresponds to the number of first slots 103. By setting two or more first slots 103 and first blocks 21, the torsional force that occurs when the first connector 1 and the second connector 2 rotate relative to each other can be evenly distributed on multiple first blocks 21, thereby reducing the force on each first block 21, making the first blocks 21 less prone to damage, and improving the service life of the second connector 2.

[0023] The present invention provides an insulated operating rod quick-connect head. Compared with the prior art, when in use, the second connector 2 is inserted into the first slot 101, and the first locking block 21 is inserted into the first slot 103 to restrict the relative rotation of the first connector 1 and the second connector 2. The connecting clip is inserted and engaged with the locking component, and the locking component locks the connecting clip to restrict the longitudinal movement of the first connector 1 relative to the second connector 2. The insulated operating rod quick-connect head provided by the present invention has a fast connection speed. By simultaneously restricting the relative rotation and axial relative movement of the first connector 1 and the second connector 2, the connection strength between the first connector 1 and the second connector 2 is strong and not easy to loosen.

[0024] In this embodiment, a first connecting groove 102 is provided on the upper end face of the first connector 1. In application, the lower end of the working head is inserted into the first connecting groove 102. The working head can be glued to the first connecting groove 102 or fixed to the first connector 1 by a pin. A second connecting groove 202 is provided on the lower end face of the second connector 2. In application, one end of the insulating rod is inserted into the second connecting groove 202. Similarly, the insulating rod can be glued to the second connecting groove 202 or fixed to the second connector 2 by a pin.

[0025] In some embodiments, please refer to Figures 3 to 9 The connecting head includes a connecting rod 11. The end of the connecting rod 11 near the port of the first slot 101 is provided with a threaded section 111. The upper end face of the second connector 2 (when in use, the end face of the second connector 2 faces the first connector 1) is provided with a first mounting groove 201. The first mounting groove 201 is a circular groove. The first mounting groove 201 is concentrically arranged with the second connector 2. The locking component is installed in the first mounting groove 201.

[0026] In this embodiment, the locking assembly includes a fixing block 3, a locking sleeve, and a driving part. The fixing block 3 includes a first block 31 and a second block 32 that are detachably connected vertically. The first block 31 and the second block 32 are fixed by bolts. The first block 31 has a disc-shaped structure, and its outer diameter is approximately the same as the outer diameter of the second connector 2. The second block 32 has a cylindrical structure, and its outer diameter is approximately the same as the inner diameter of the first mounting groove 201. In use, the second block 32 is inserted into the first mounting groove 201. A first block 31 is attached to the port of the first mounting groove 201 and bolted to the second connector 2. An annular boss 311 is provided in the middle of the lower end face of the first block 31, forming a first storage groove 312 in the middle of the annular boss 311. A second storage groove is provided in the middle of the upper end face of the second block 32. The second storage groove includes a first groove 321 and a second groove 322 connected vertically. The first groove 321 is adapted to the annular boss 311, and the inner diameter of the second groove 322 is larger than the inner diameter of the first storage groove 312. Similar to the previous example, in application, after the first block 31 is connected to the second block 32, the annular boss 311 is inserted into the first groove 321. The second groove 322 is opposite to and concentrically arranged with the first storage groove 312. The space between the second groove 322 and the first storage groove 312 forms the second mounting groove 301 in the middle of the fixing block 3. The locking sleeve is rotatably connected in the second mounting groove 301. The middle part of the locking sleeve has a threaded hole 41 that mates with the threaded section 111 on the connecting rod 11. A second mounting groove 301 is also provided at the center of the upper end face of the first block 31. A first clearance hole 302 is provided, which extends downward through the first block 31 and communicates with the first storage groove 312. It is also coaxially arranged with the threaded hole 41 provided on the locking sleeve. In application, during the process of the first connector 1 being inserted downward into the second connector 2, the driving part drives the locking sleeve to rotate. The threaded section 111 on the connecting rod 11 moves downward through the first clearance hole 302 and is threadedly connected in the threaded hole 41 of the locking sleeve. By making the connecting rod 11 threadedly connected to the locking sleeve, the axial movement of the first connector 1 relative to the second connector 2 can be restricted.

[0027] In this embodiment, in order to smoothly connect the threaded section 111 on the connecting rod 11 into the threaded hole 41 on the locking sleeve, a guide hole 42 is also connected to the upper end of the threaded hole 41, and the inner wall of the guide hole 42 is inclined from top to bottom inward. With this setting, the threaded section 111 can be smoothly guided into the threaded hole 41 through the guiding effect of the guide hole 42.

[0028] In this embodiment, please refer to Figure 3 , Figures 7 to 9A third mounting groove 204 is provided at the lower end of the second block 32. The third mounting groove 204 is longitudinally arranged on the side wall of the second block 32. In this embodiment, there are two third mounting grooves 204, which are symmetrically arranged on both sides of the second storage slot. A longitudinal groove 304 is provided between the third mounting groove 204 and the second storage slot. The longitudinal groove 304 connects the third mounting groove 204 and the second storage slot. The bottom of the longitudinal groove 304 is located above the bottom of the second slot 322 or flush with the bottom of the second slot 322. A first groove 401 is provided on the circumferential sidewall of the locking sleeve. In this embodiment, the upper end of the first groove 401 extends upward through the upper end face of the locking sleeve, and the lower end face of the first groove 401 extends downward through the lower end face of the locking sleeve. The first groove 401 is spirally arranged from top to bottom within half of the outer circumference of the locking sleeve. In this embodiment, there are two first grooves 401, and the two first grooves 401 are evenly distributed on the outer circumference of the locking sleeve.

[0029] In this embodiment, please refer to Figures 3 to 7 The driving unit includes a first slider 5 and a driving plate 6. There are two first sliders 5, which are slidably connected in the third mounting groove 204. A crossbar 51 is connected to the side of the first slider 5 facing the longitudinal groove 304. The end of the crossbar 51 away from the first slider 5 passes through the longitudinal groove 304 and is inserted into one of the first sliding grooves 401 on the circumferential side wall of the locking disc 4. It is easy to understand that the crossbars 51 of the two first sliders 5 are respectively inserted into the first sliding grooves 401 on the same side. The driving plate 6 is slidably disposed in the first mounting groove 201 and is located below the second block 32. There is a space for movement between the driving plate 6 and the bottom of the first mounting groove 201. The first slider 5 and the driving plate 6 are connected by the longitudinal rod 52. In use, by moving the driving plate 6 downward, the first block 31 can be driven to slide downward, causing the crossbar 51 to move downward. The end of the crossbar 51 inserted in the first sliding groove 401 slides from the upper end of the groove to the lower end, which can drive the locking sleeve to rotate.

[0030] In this embodiment, please refer to Figures 3 to 7The connecting rod 11 on the first connector 1 also has an abutment section 112, which is connected to the lower end of the threaded section 111. In this embodiment, the diameter of the abutment section 112 is smaller than the diameter of the threaded section 111. During the process of inserting the first connector 1 into the second connector 2, as the connecting rod 11 moves downward, the abutment section 112 preferentially passes through the first clearance hole 302, the threaded hole 41 and the second clearance hole 303 in sequence and presses against the drive plate 6. As the connecting rod 11 moves further downward, the abutment section 112 can push the drive plate 6 to move downward in the first mounting hole, thereby causing the locking disc 4 to start rotating. The threaded section 111 connected to the upper end of the abutment section 112 is threadedly connected, so that the connecting rod 11 and the locking disc 4 are locked to each other through the engagement of the threaded hole 41 and the threaded section 111, thus restricting the axial movement of the first connector 1 and the second connector 2.

[0031] In some embodiments, please refer to Figures 1 to 3 A second slot 203 is longitudinally provided on the side wall of the second connector 2. The number of second slots 203 is adapted to the number of first slots 21. A second slot 22 is slidably disposed in the second slot 203. In this embodiment, the second slot 22 is connected to the side wall of the first slot 21 facing the second connector 2. Preferably, the first slot 21 and the second slot 22 are integrally formed. In application, when the first connector 1 is inserted into the second connector 2, the first slot 21 is inserted into the first slot 103 on the first connector 1, and the second slot 22 is inserted into the second slot 203 of the second connector 2. By means of the cooperation between the first slot 21 and the first slot 103 and the second slot 22 and the second slot 203, the relative rotation of the first connector 1 and the second connector 2 can be restricted. When it is necessary to separate the first connector 1 and the second connector 2, the second locking block 22 slides downward in the second locking groove 203, which drives the first locking block 21 to move downward, so that the first locking block 21 is disengaged from the first locking groove 103, and the relative rotation between the first connector 1 and the second connector 2 is no longer restricted. The connecting rod 11 can be disengaged from the threaded hole 41 in the locking disc 4 by rotating the first connector 1, thereby separating the first connector 1 and the second connector 2.

[0032] Optionally, in order to enable the drive plate 6 to automatically reset when the first connector 1 is separated from the second connector 2, a first spring 61 is provided between the bottom surface of the first mounting groove 201 and the drive plate 6. When the first connector 1 and the second connector 2 are inserted and engaged, the drive plate 6 moves downward to compress the first spring 61. When the first connector 1 and the second connector 2 are separated, the first spring 61 releases its elastic force to drive the drive plate 6 to move upward to reset.

[0033] Further, please refer to Figures 1 to 3A movable sleeve 23 is slidably fitted on the second connector 2. A first locking block 21 is connected to the movable sleeve 23. An annular stop block 24 is circumferentially arranged on the side wall of the second connector 2. The annular stop block 24 is located below the movable sleeve 23. A second spring 25 is also threaded through the second connector 2. The second spring 25 is connected between the movable sleeve 23 and the annular stop block 24. In application, when the second spring 25 is in a free state, the first locking block 21 is in a first position. The first locking block 21 can form an insertion fit with the first slot 103. By sliding the movable sleeve 23 downward to compress the second spring 25, the first locking block 21 can be moved to a second position, so that the first locking block 21 is disengaged from the first slot 103.

[0034] The present invention also provides an insulated operating rod, including an insulated rod and a working head, wherein the insulated rod and the working head are connected by the aforementioned insulated operating rod quick-release head.

[0035] The beneficial effects of the insulating operating rod provided by the present invention are as follows: Compared with the prior art, the insulating operating rod of the present invention uses the above-mentioned quick-release head of the insulating operating rod to connect the insulating rod and the working head, and has all the beneficial effects of the above-mentioned quick-release head of the insulating operating rod. In use, the second connector 2 is inserted into the first slot 101, and the first locking block 21 is inserted into the first slot 103 to restrict the relative rotation of the first connector 1 and the second connector 2. The connecting clip is inserted and engaged with the locking component, and the locking component locks the connecting clip to restrict the longitudinal movement of the first connector 1 relative to the second connector 2. The insulating operating rod provided by the present invention, by using the above-mentioned quick-release head of the insulating operating rod, enables the connection speed between the insulating rod and the working head to be fast, and can simultaneously restrict the relative rotation and axial relative movement between the working head and the insulating rod, so that the connection strength between the working head and the insulating rod is strong and not easy to loosen.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
