DETAILED DESCRIPTION

[0033] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] In one embodiment, Figures 1 to 5 As shown, the embodiment of the present application provides a transmission rod locking device 100, which may specifically include a first fastening assembly 110, a second fastening assembly 120 and a locking assembly 130, wherein the first fastening assembly 110 is mainly used to realize a detachable fastening connection between the transmission rod locking device 100 and the fixed rod body 200. The second fastening assembly 120 is mainly used to realize a detachable fastening connection between the transmission rod locking device 100 and the transmission rod 310. The locking assembly 130 is mainly used to realize a locking connection between the first fastening assembly 110 and the second fastening assembly 120, so that the transmission rod 310 is locked and fixed on the fixed rod body 200.

[0035] It can be understood that the transmission rod locking device 100 of the embodiment of the present application is mainly used in the transmission rod locking knife switch of the power equipment. The transmission rod locking knife switch is installed on the fixed rod body 200, and includes a transmission rod 310 for controlling the opening and closing of the transmission rod locking knife switch, that is, the transmission rod locking knife switch can be opened and closed by the control of the transmission rod 310 to control the power on and off of the corresponding power equipment. The fixed rod body 200 mentioned above can specifically be a cement cylinder at the installation site of the power equipment. The fixed rod body 200 can not only provide a reliable support point for the installation of the transmission rod locking knife switch, but also provide a reliable support point for the installation of the transmission rod locking device 100. The fixed rod bodies 200 installed by the two can be the same fixed rod body 200 or two different fixed rod bodies 200. It is only necessary to ensure that the fixed rod body 200 detachably fastened to the first fastening assembly 110 is arranged adjacent to the transmission rod 310 body. The above-mentioned detachable fastening connection can be a common detachable connection structure such as a screw structure and a buckle structure, so that the first fastening assembly 110 can be installed and fixed on the fixed rod body 200 at any time according to actual needs, or removed from the fixed rod body 200, and the second fastening assembly can be installed and fixed on the transmission rod 310 at any time according to actual needs, or removed from the transmission rod 310. The above-mentioned locking assembly 130 can specifically include a conventional lock structure, so that after the first fastening assembly 110 and the second fastening assembly 120 are connected together, the connection is locked by the lock structure, so that the connection cannot be easily released, and the transmission rod 310 is locked and fixed on the fixed rod body 200.

[0036] In this way, the transmission rod locking device 100 of the embodiment of the present application, through the above-mentioned structural setting, can first fasten the first fastening component 110 to the fixed rod body 200 on site, and fasten the second fastening component 120 to the transmission rod 310 of the transmission rod locking knife switch before repairing and maintaining the power equipment, and then lock the first fastening component 110 and the second fastening component 120 together through the locking component 130, so that the transmission rod 310 is locked and fixed on the fixed rod body 200, and then during the repair and maintenance process, even if an erroneous operation occurs, the transmission rod 310 is locked and there will be no danger caused by the erroneous opening and closing of the transmission rod locking knife switch, so that the safety of the site can be guaranteed. At the same time, through the detachable connection of the first fastening component 110 and the second fastening component 120, it can be ensured that the transmission rod locking device 100 can be disassembled and used on site, which brings great convenience to the maintenance personnel.

[0037] In some examples, such as Figures 1 to 5As shown, the locking assembly 130 includes a first connection module 131, a second connection module 132 and a locking module 133, wherein the first connection module 131 mainly includes a first end and a second end that are fastened and connected, the first end is fixed on the first fastening assembly 110, and the second end is provided with a first matching portion. The second connection module 132 mainly includes a third end and a fourth end that are fastened and connected, the third end is fixed on the second fastening assembly 120, and the fourth end is provided with a second matching portion. The locking module 133 is mainly used to lock the first matching portion and the second matching portion when the first matching portion and the second matching portion are plugged and matched. In this way, through the above-mentioned structural setting, the first matching portion and the second matching portion that are plugged and matched together can be locked by the locking module 133, so as to realize the locking connection between the first fastening assembly 110 and the second fastening assembly 120, thereby better locking and fixing the transmission rod 310 on the fixed rod body 200.

[0038] It is understandable that the fastening connection between the first end and the first fastening assembly 110 can be a non-detachable fastening connection, such as an integrated structure setting, welding fixation, etc., or a detachable fastening connection, such as a screw connection, a buckle connection, etc. Similarly, the fastening connection between the third end and the second fastening assembly 120 can also be a non-detachable fastening connection, such as an integrated structure setting, welding fixation, etc., or a detachable fastening connection, such as a screw connection, a buckle connection, etc.

[0039] In some examples, such as Figures 3 to 5As shown, the first matching part may specifically include a first matching surface 1311 disposed at the second end and a buckling groove 1312 recessed on the first matching surface 1311. The second matching part may specifically include a second matching surface 1321 disposed at the fourth end and a buckling protrusion 1322 convexly disposed on the second matching surface 1321. The second matching surface 1321 is in abutment with the first matching surface 1311, and the buckling protrusion 1322 is plugged into the buckling groove 1312. In this way, through the above-mentioned structural setting, it is easy to align the plug-in fit between the first matching part and the second matching part, while ensuring that the plug-in fit between the first matching part and the second matching part is tighter. Further, the first matching part also includes a clearance hole 1313 opened at the second end, and the second matching part also includes a first fixing part 1323 and a second fixing part 1324 convexly disposed on the buckling protrusion 1322, respectively, the first fixing part 1323 is provided with a first fixing hole 1325, and the second fixing part 1324 is provided with a second fixing hole 1326. The locking module 133 includes a fixed shaft 1331 and a lock body structure 1332. When the first matching part and the second matching part are plugged and matched, the fixed shaft 1331 can be inserted into the first fixing hole 1325, the clearance hole 1313 and the second fixing hole 1326 that are aligned in sequence, and locked by the lock body structure 1332 installed on the first fixing part 1323 or the second fixing part 1324, thereby locking the first matching part and the second matching part. In this way, through the above-mentioned structural setting, when the fixed shaft 1331 is inserted into the first fixing hole 1325, the clearance hole 1313 and the second fixing hole 1326 that are aligned in sequence to connect the first matching part and the second matching part together, the fixed shaft 1331 can be locked by the lock body structure 1332 installed on the first fixing part 1323 or the second fixing part 1324, thereby locking the first matching part and the second matching part. Since the lock structure 1332 requires a key (electronic key or mechanical key) to unlock, the safety of the transmission rod 310 being locked and fixed on the fixed rod body 200 can be further ensured.

[0040] It is understandable that the lock body structure 1332 mentioned above is preferably installed on the second fixing portion 1324, which can be a common electronic lock body structure 1332 to realize the unlocking function by password or electronic key, or a mechanical lock body structure 1332 as shown in the figure to realize the corresponding unlocking function by controlling the rotation of the lock cylinder by an adapted key. When the user controls the rotation of the lock cylinder by an adapted key to lock, the corresponding locking pin can be controlled to extend against the fixed shaft 1331 to lock the fixed shaft 1331. In order to make the fixed shaft 1331 better locked by the extended locking pin, the circumference of the fixed shaft 1331 can be concavely provided with a corresponding card slot 10.

[0041] In some examples, such as Figures 3 to 5As shown, the locking assembly 130 specifically further includes a state detection module 134, the state detection module 134 includes a state detection structure 1341 and a magnetic element 1342, the state detection structure 1341 includes a magnetic detection module for detecting the position of the magnetic element 1342, and the magnetic element 1342 is installed at the fourth end or the second end. The fixed shaft 1331 includes a mounting portion and an insertion portion that are connected to each other, the mounting portion is equipped with the state detection structure 1341, and when the first matching portion and the second matching portion are plugged and matched, the insertion portion can be inserted into the first fixing hole 1325, the clearance hole 1313 and the second fixing hole 1326 that are aligned in sequence. In this way, through the above-mentioned structural setting, when the insertion portion of the fixed shaft 1331 is aligned with the first fixing hole 1325, the yield hole 1313 and the second fixing hole 1326 in sequence and is locked by the lock body structure 1332 installed on the first fixing portion 1323 or the second fixing portion 1324, the magnetic detection module on the mounting portion of the fixed shaft 1331 can detect the position of the magnetic element 1342 on the fourth end or the second end, so as to detect whether the fixed shaft 1331 connects the first matching portion and the second matching portion together. After the fixed shaft 1331 connects the first matching part and the second matching part together, the fixed shaft 1331 will be locked by the lock body structure 1332 by default, so as to realize the locking operation of the transmission rod locking device 100. The unlocking operation of the transmission rod locking device 100 can only be completed when the lock body structure 1332 unlocks the fixed shaft 1331, so that the fixed shaft 1331 no longer connects the first matching part and the second matching part together (that is, the fixed shaft 1331 is completely separated from the first fixing hole 1325, the clearance hole 1313 and the second fixing hole 1326 that are aligned in sequence). Therefore, this detection can also be used as a detection of the unlocking state of the transmission rod locking device 100 in a non-strict sense. Further, the locking assembly 130 also includes a wireless code chip 1343, which is installed at the fourth end or the second end. The state detection structure 1341 also includes a controller, a wireless data transmission module, and an identification and reading module for identifying the wireless code chip 1343. The controller is electrically connected to the magnetic detection module, the wireless data transmission module, and the identification and reading module. Among them, the wireless code chip 1343 has a unique code value, which can locate the transmission rod locking device 100, ensuring that the monitoring background can accurately monitor the transmission rod locking device 100 used in different positions. In this way, through the above-mentioned structural setting, it is ensured that the transmission rod locking device 100 can automatically realize the corresponding state identification and position positioning, and upload it to the monitoring background in real time to maintain real-time contact with the monitoring background.

[0042] It is understandable that the magnetic element 1342 mentioned above is preferably a magnetic steel, which can be preferably fixedly installed on the fourth end through the first installation slot 12 provided on the fourth end. Similarly, the wireless code chip 1343 can also be preferably fixedly installed on the fourth end through the second installation slot 13 provided on the fourth end.

[0043] In some examples, such as Figures 1 to 5 As shown, the first fastening assembly 110 may specifically include a U-shaped screw 111, a nut 112 and a fixing plate 113. The U-shaped screw 111 is arranged around the fixing rod body 200, and is fastened to the fixing rod body 200 through the cooperation of the fixing plate 113 and the nut 112. The first end is fixed on the fixing plate 113. In this way, through the above-mentioned structural arrangement, the columnar structure of the fixing rod body 200 can be better matched, so that the detachable fastening connection between the first fastening assembly 110 and the fixing rod body 200 becomes tighter and more secure. At the same time, through the arrangement of the fixing plate 113, a reliable support point is provided for the fixation of the entire device. Further, the first end includes a flat plate portion 1314 and a guide rod portion 1315 arranged in contact with each other. The flat plate portion 1314 is fastened to the fixing plate 113 through a screw structure, and a flat position 11 is arranged on the peripheral side of the guide rod portion 1315. A sleeve portion 1316 is also provided on the side of the second end away from the first matching portion, and the sleeve portion 1316 and the guide rod portion 1315 are movably plugged and matched in the extending direction of the guide rod portion 1315, and are fastened and connected at least in two positions through a pin structure to achieve a telescopic fastening connection between the first end and the second end. That is, by sleeve portion 1316 being sleeved on different positions of the guide rod portion 1315, the second end can have at least a first position and a second position relative to the first end, and when the second end is in the first position, it is closer to the first end than when it is in the second position. In this way, through the above-mentioned structural arrangement, when the second end is in the second position, the first matching portion can be plugged and matched with the second matching portion, so that the first fixing hole 1325, the clearance hole 1313 and the second fixing hole 1326 can be aligned in sequence, at this time, the fixed shaft 1331 can be inserted, and the fixed shaft 1331 can be locked by the lock body structure 1332 to lock the first matching portion and the second matching portion, so that the transmission rod 310 is locked. When there is no need to lock the transmission rod 310 temporarily, the locking of the fixed shaft 1331 by the lock body structure 1332 can be released. After the fixed shaft 1331 is pulled out, the first mating part is no longer plugged into the second mating part by switching the second end from the second position to the first position, so that the first connecting module 131 and the second connecting module are separated 132, and the locking state of the transmission rod 310 is completely released without completely dismantling the transmission rod locking device 100 to completely release the locking state of the transmission rod 310.

[0044] It is understandable that the specific number of the U-shaped screws 111 mentioned above can be arbitrarily increased or decreased according to the actual fastening requirements of the first fastening assembly 110 on the corresponding fixed rod body 200 to ensure that the first fastening assembly 110 can be quickly and firmly fastened to the corresponding fixed rod body 200.

[0045] In some examples, such as Figures 1 to 5As shown, the second fastening assembly 120 includes a first semicircular hoop 121 and a second semicircular hoop 122. The first semicircular hoop 121 is movably fixed on the third end, and is fastened to the transmission rod 310 through the cooperation of the second semicircular hoop 122 and the screw structure. In this way, through the above-mentioned structural setting, the columnar structure of the transmission rod 310 can be better matched, so that the detachable fastening connection between the second fastening assembly 120 and the transmission rod 310 becomes tighter and stronger. Furthermore, a semicircular mounting portion 1327 is provided at the third end, and an arc-shaped step groove 1328 is provided along the extension direction of the semicircular mounting portion 1327, and the arc-shaped step groove 1328 includes a first surface and a second surface which are perpendicular to each other, and an arc-shaped adjustment hole 14 is provided on the first surface, and an engaging inner tooth 15 is provided on the second surface, and an engaging outer tooth 16 which cooperates with the engaging inner tooth 15 is provided on the side of the first semicircular clamp 121 away from the second semicircular clamp 122, and a bolt hole is also provided on the first semicircular clamp 121, so that when the engaging outer tooth 16 of the first semicircular clamp 121 is engaged with the engaging inner tooth 15, the bolt hole is fastened to any position of the arc-shaped adjustment hole 14 through the bolt structure. In this way, through the above-mentioned structural setting, while ensuring a tighter fastening connection between the first semicircular clamp 121 and the semicircular mounting portion 1327, the installation angle of the first semicircular clamp 121 on the semicircular mounting portion 1327 can be accurately adjusted through the arc-shaped adjustment hole 14. Furthermore, a limiting protrusion 17 is also protruded on the one side surface of the first semicircular clamp 121 and the second semicircular clamp 122, through which the first semicircular clamp 121 and the second semicircular clamp 122 can be further clamped and fixed on the flange 320 of the transmission rod 310, thereby ensuring that the first semicircular clamp 121 and the second semicircular clamp 122 can tightly hold the column transmission rod 310.

[0046] It can be understood that the side of the second semicircular hoop 122 mentioned above away from the first semicircular hoop 121 can also be provided with meshing external teeth 16 that cooperate with the meshing internal teeth 15, so that the structure of the second semicircular hoop 122 and the first semicircular hoop 121 remains completely symmetrical, reducing the difficulty of hoop manufacturing.

[0047] In summary, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
