[0036] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0037] like Figure 4An operating rod splicing structure 1000 shown includes a first end 100 and a second end 200, the first end 100 includes a first main body 11 and a pin assembly 12, the first main body 11 is provided with a first threaded portion 01, the first threaded portion 01 is used for threaded connection with the second end 200, the pin assembly 12 is arranged on the first main body 11, and the pin assembly 12 is used to make the first end 100 and the second end 200 engage and fix with each other.

[0038] The second end 200 is plugged with the first end 100, and a clamping portion 211 and a second threaded portion 02 are provided on the second end 200, wherein the second threaded portion 02 is used to be threadedly connected with the first threaded portion 01, so that the first end 100 and the second end 200 are threadedly connected and fixed. When the first end 100 and the second end 200 are plugged with each other and connected and fixed by the first threaded portion 01 and the second threaded portion 02, the above-mentioned elastic pin assembly 12 can be engaged with the clamping portion 211. In the above manner, after the first end 100 and the second end 200 are threadedly connected by the first threaded portion 01 and the second threaded portion 02, the elastic pin assembly 12 can be engaged with the clamping portion 211, so that the first end 100 and the second end 200 cannot rotate relative to each other, thereby making the first end 100 and the second end 200 more firmly connected.

[0039] In addition, the first threaded portion 01 and the second threaded portion 02 are both made of a lightweight non-metallic material with a certain deformation ability. Preferably, the first threaded portion 01 and the second threaded portion 02 are made of hard rubber. The hard rubber material is cheap and has good insulation properties as well as a certain deformation ability and good wear resistance. In this way, when the first threaded portion 01 and the second threaded portion 02 are screwed together, the threads are not easily worn and there should be no jamming.

[0040] The following will introduce the technical details of each component one by one.

[0041] In some embodiments, Figure 1 , Figure 2 As shown, the first body 11 includes a connecting rod 111 and an insertion rod 112. The connecting rod 111 is used to fix the first end 100 on the end of the rod bodies spliced ​​together. The insertion end is connected to the connecting rod 111 and is used to be plugged with the second end 200. The elastic pin assembly 12 is arranged on the insertion rod 112, and part of the elastic pin assembly 12 protrudes from the side of the insertion rod 112.

[0042] In practical applications, the insertion rod 112 may be made of a relatively strong metal material because it needs to be plugged with the second end 200. Preferably, the insertion rod 112 may be a metal hollow tube, which is relatively light and relatively strong. The connecting end may be made of a light non-metal material with a certain deformation ability. Preferably, the connecting end may be made of hard rubber. Through the above design, the operating rod splicing structure 1000 may be light in weight and not easy to get stuck.

[0043] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the insertion rod 112 is provided with a receiving cavity 03 inside, and the elastic pin assembly 12 is arranged inside the receiving cavity 03, which can provide a relatively safe working environment for the elastic pin assembly 12 and reduce the possibility of failure of the elastic pin assembly 12.

[0044] The above-mentioned elastic pin assembly 12 includes an elastic member 121 and a latch pin 122. The elastic member 121 is used to provide elastic force for the latch pin 122 and elastically abut against the inner wall of the accommodating cavity 03. The latch pin 122 is fixedly connected to the elastic end of the elastic member 121. The latch pin 122 can protrude from the side wall of the insertion rod 112 and engage with the engaging portion 211 of the second end 200 under the abutment of the elastic member 121. In actual applications, the elastic engagement method of the latch pin 122 has the advantages of simple structure and not easy to be damaged.

[0045] It can be understood that in order to allow the pin assembly 12 to be more stably arranged inside the accommodating chamber 03, a limiting groove is opened at the abutment point between the elastic member 121 and the inner wall of the accommodating chamber 03. The limiting groove can limit the position of the elastic member 121 inside the accommodating chamber 03 to prevent the pin assembly 12 from being offset due to factors such as vibration and impact.

[0046] In some embodiments, Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the second end 200 includes a second body 21 and a pressing member 22. The engaging portion 211 on the second end 200 is arranged on the second body 21. The pressing member 22 is movably arranged on the engaging portion 211. The pressing member 22 can move from a first predetermined position to a second predetermined position. When the first end 100 and the second end 200 are connected to each other, at this time, the latch 122 is engaged with the engaging portion 211. The pressing member 22 is used to push the latch 122 out to disengage the latch 122 from the engaging portion 211, so that the first end 100 and the second end 200 can be brought into contact with each other and engaged, so that the first end 100 and the second end 200 can be screwed together and separated.

[0047] In actual applications, the method of pressing the latch 122 by the pressing member 22 is easier to push the latch 122 out to disengage the engaging portion 211 than the traditional method of directly pressing the latch 122. Moreover, the traditional method of directly pressing the latch 122 may cause certain dangers to the operator's fingers. The method of indirectly pressing the latch 122 by the pressing member 22 is safer and more stable.

[0048] In some embodiments, Figure 5 , Figure 6 As shown, the pressing member 22 includes a spring piece 221 and a needle 222. One end of the spring piece 221 is fixedly connected to the second body 21, and the other end is connected to the needle 222. Correspondingly, the engaging portion 211 is provided with an engaging hole 04, and the needle 222 can be inserted into the engaging hole 04.

[0049] In actual application, when the latch 122 is engaged with the engaging portion 211, the latch 122 is inserted into the engaging hole 04, and the needle 222 can be inserted into the engaging hole 04 to support the latch 122; in this way, when the pressing piece 22 is pressed hard, the needle 222 can push the latch 122 out of the engaging hole 04, so that the latch 122 is disengaged from the engaging portion 211. In this way, the latch 122 can be indirectly pushed out of the engaging portion 211 by pressing the pressing piece 22. In addition, the spring piece 221 can also make the needle 222 always inserted in the engaging hole 04, so that the needle 222 will not be disengaged from the engaging hole 04 due to shaking, so that the operator can press the latch 122 through the pressing piece 22.

[0050] It can be understood that in order to ensure that the pressing piece 22 can always be in contact with the latch 122 so as to facilitate pushing the latch 122 out of the engagement hole 04, the end of the needle 222 used to abut against the latch 122 has magnetism, and correspondingly, the latch 122 is usually made of a metal material containing iron. In this way, the needle 222 and the latch 122 can always maintain a contact state through magnetic attraction after the first end 100 and the second end 200 are connected. In this way, when the operator separates the first end 100 and the second end 200 and presses the pressing piece 22, there is no need to manually align the needle 222 with the latch 122 for abutment, which greatly facilitates the disassembly process of the operating rod splicing structure 1000.

[0051] In some embodiments, Figure 4 As shown, a ring protrusion 212 is arranged around the fixed connection between the second body 21 and the elastic piece 221 . The ring protrusion 212 protrudes from the surface of the second body 21 to a certain height, and the protruding height of the ring protrusion 212 is greater than the thickness of the elastic piece 221 .

[0052] In practical applications, since the spring piece 221 can usually be a plastic carbon sheet, or a rubber or silicone strip, these materials are easy to break or scratch, and the spring piece 221 is arranged on the outer surface of the second body 21, it is easy to be squeezed and contacted with other objects, and thus the spring piece 221 is easy to be scratched or broken. After the ring protrusion 212 is arranged, when the side of the second body 21 where the spring piece 221 is located contacts the surface of other objects, the ring body can support an escape space between the surface of the second body 21 and the other object to prevent the spring piece 221 from being squeezed, so that the spring piece 221 can be protected.

[0053] In some embodiments, Figure 4 As shown, the first end 100 and the second end 200 are respectively provided with a first identification portion 13 and a second identification portion 23 . When the elastic pin assembly 12 is engaged with the engaging portion 211 , the first identification portion 13 and the second identification portion 23 are aligned with each other.

[0054] It can be understood that the engagement of the pin assembly 12 and the engaging portion 211 requires that the first end 100 and the second end 200 can be aligned and engaged with each other only after they are screwed together to a certain extent through the first threaded portion 01 and the second threaded portion 02. During the process of connecting the first end 100 and the second end 200 to each other, the operator cannot directly observe the relative position of the pin assembly 12 and the engaging portion 211. Therefore, in order to facilitate the operator to pre-judge the relative position of the pin assembly 12 and the engaging portion 211, the operator can determine whether the pin assembly 12 and the engaging portion 211 can be engaged by observing whether the first identification portion 13 and the second identification portion 23 are aligned.

[0055] The present application also provides an insulating operating rod, which includes multiple insulating rod bodies 2000 and the above-mentioned operating rod splicing structure 1000, wherein the first end 100 and the second end 200 of the above-mentioned operating rod splicing structure 1000 are respectively arranged at the connecting ends of two interconnected insulating rod bodies 2000, so that two adjacent insulating rod bodies 2000 can be quickly spliced ​​through the operating rod splicing structure 1000.

[0056] like Figure 1 As shown, the insulating rod body 2000 is provided with a first end 100 and a second end 200 at opposite ends thereof. When multiple insulating rod bodies 2000 are connected, the insulating operating rod can be quickly and firmly spliced ​​by simply plugging and threading the first end 100 on one insulating rod body 2000 with the second end 200 on another insulating rod body 2000 and then engaging the elastic pin assembly 12.

[0057] In practical applications, the insulating rod body 2000 is made of a relatively light insulating material, which has excellent insulation performance and is relatively light, making it convenient for operators to use. In addition, the first threaded portion 01 and the second threaded portion 02 respectively arranged on the first end 100 and the second end 200 in the operating rod splicing structure 1000 are made of a light non-metallic material with a certain deformation ability; preferably, the first threaded portion 01 and the second threaded portion 02 can be made of hard rubber, which has good insulation properties, which is also conducive to improving the insulation performance of the insulating operating rod. Since the hard rubber also has a certain deformation ability, the insulating operating rod is not prone to getting stuck when the threads are screwed together.

[0058] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
