[0036] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] like Figure 1 and Figure 2As shown, the present invention provides a spacing device 1 for parallel wires, including two line connection structures 10 and a spacing connection structure 11. The line connection structure 10 includes a main body 101 and a fastening member 102 movably connected to the main body 101. The main body 101 has a first end 1011 and a second end 1012 opposite to each other. The fastening member 102 can be detachably fastened to the main body 101, so that a receiving through hole 103 is formed between the fastening member 102 and the main body 101 near the first end 1011. The two line connection structures 10 are respectively used to clamp and connect two parallel wires 2 to the receiving through hole 103. The spacing connection structure 11 is respectively connected to the two second ends 1012 of the two line connection structures 10, so that the two second ends 1012 are spaced apart.

[0040] By making the line connection structure 10 include a main body 101 and a fastening member 102 that can be movably connected, the line connection structure 10 can clamp the wire 2 in the accommodating through hole 103 formed between the fastening member 102 and the main body 101 by fastening the fastening member 102 to the main body 101. Therefore, on the one hand, there is no need to use a threaded member near the wire 2, so as to avoid damage to the wire 2 when the line connection structure 10 is manually connected to the wire 2. On the other hand, the clamping force applied by the line connection structure 10 to the wire 2 is determined by the size of the accommodating through hole 103 formed between the fastening member 102 and the main body 101 when the fastening member 102 is fastened to the main body 101. In other words, the clamping force of the line connection structure 10 on the wire 2 will not be too large due to manual operation during the manual installation process, so as to avoid damage to the wire 2 caused by the spacing device 1 during use.

[0041] In order to improve the stability of the fastening connection between the fastening member 102 and the main body 101 when they are fastened together, the stability of the fastening connection between the fastening member 102 and the main body 101 can be enhanced in a variety of different ways.

[0042] Please combine Figure 3 and Figure 4As shown, in an optional example, the snap-fitting part 102 is provided with a gear 1040, and the gear 1040 is coaxial with the rotation axis of the snap-fitting part 102 relative to the main part 101, and the main part 101 is rotatably provided with a clamping strip 1041, and a first elastic member 1042 is also connected between the clamping strip 1041 and the main part 101, and one side of the clamping strip 1041 can abut against the main part 101, and when one side of the clamping strip 1041 abuts against the main part 101, one end of the clamping strip 1041 extends into the gap between two adjacent teeth of the gear 1040, and the clamping strip 1041 can rotate relative to the main part 101 until the clamping strip 1041 is located on the outer peripheral side of the gear 1040 as a whole, and the first elastic member 1042 can apply elastic force to the clamping strip 1041, so that the clamping strip 1041 has a tendency to rotate relative to the main part 101 until it abuts against the main part 101.

[0043] It can be understood that, in the process of rotating the fastening member 102 relative to the main body 101 until it is fastened to the first end 1011, the gear 1040 rotates relative to the main body 101 in one direction to be able to move the end of the clip 1041, so that the clip 1041 rotates relative to the main body 101, and the first elastic member 1042 is compressed or stretched to increase the elastic restoring force applied to the fastening member 102. When the fastening member 102 is fastened in place, if the gear 1040 rotates in the opposite direction of the aforementioned direction, the clip 1041 can be rotated. One side of 41 will abut against the main body 101, so that the end of the clip 1041 extending into the gap between two adjacent teeth of the gear 1040 can prevent the gear 1040 from rotating in the direction opposite to the aforementioned direction. In other words, the relative posture of the gear 1040 and the main body 101 can be limited by the clip 1041 to limit the relative rotation position of the fastening member 102 relative to the main body 101, so that the fastening member 102 can be maintained in the position fastened to the main body 101 under the limiting action of the clip 1041.

[0044] Furthermore, when it is necessary to release the fastening connection between the fastening component 102 and the main body 101, the operator can manually move the clamping strip 1041 relative to the main body 101 until the first elastic component 1042 is compressed or stretched to increase the elastic restoring force applied to the fastening component 102, so that one end of the clamping strip 1041 is disengaged from the gap between two adjacent teeth of the gear 1040, and then the fastening component 102 is bendable to separate the fastening component 102 from the first end 1011, thereby releasing the fastening connection between the fastening component 102 and the main body 101.

[0045] Optionally, an operating structure may be provided on the clamping strip 1041 so as to protrude toward the outside of the spacing device 1 , and the operating structure is used for an operator to grasp and move the clamping strip 1041 .

[0046] Please combine Figure 5As shown, optionally, a groove 1013 is provided on the surface of the main body 101, and the gear 1040 is at least partially located in the groove 1013. A clamping strip 1041 is rotatably provided in the groove 1013. The main body 101 is detachably connected with a cover 1014, and the cover 1014 can cover the groove 1013, so that when there is no need to manually move the clamping strip 1041, the gear 1040 and the clamping strip 1041 in the groove 1013 can be covered by the cover 1014, so as to avoid the clamping strip 1041 being moved due to unexpected circumstances, thereby avoiding the situation where the buckle 102 and the main body 101 accidentally release the clamping of the wire 2.

[0047] Exemplarily, when one end of the clamping strip 1041 extends into the gap between two adjacent teeth of the gear 1040, the side of the clamping strip 1041 away from the gear 1040 can abut against the groove wall of the groove 1013. When the clamping strip 1041 is moved by the gear 1040 or the operator relative to the main body 101 to compress the first elastic member 1042, the side of the clamping strip 1041 away from the gear 1040 can be away from the groove wall of the groove 1013. Alternatively, a raised limit block may be provided on the main body 101, and the limit block is located on one side of the clamping strip 1041 along the rotation direction relative to the main body 101. When one end of the clamping strip 1041 extends into the gap between two adjacent teeth of the gear 1040, one side of the clamping strip 1041 abuts against the limit block. When the clamping strip 1041 is moved by the gear 1040 or the operator relative to the main body 101 to compress the first elastic member 1042, one side of the clamping strip 1041 can be away from the limit block.

[0048] Please continue to read Figure 2 , Figure 4 and Figure 5 In another optional example, the fastening member 102 is used for fastening and connecting to one end of the main body 101, and is provided with a first clamping structure, and the first end 1011 is provided with a second clamping structure. One of the first clamping structure and the second clamping structure includes an elastically shrinkable clamping rod 1050, and the top of the clamping rod 1050 has a truncated cone-shaped guide section 1050a, and the other includes a clamping hole 1051. The clamping rod 1050 can be clamped in the clamping hole 1051, and along the length extension direction of the clamping rod 1050, the size of the guide section 1050a is greater than or equal to the size of the clamping hole 1051.

[0049] Taking the example that the first clamping structure includes the clamping rod 1050 and the second clamping structure includes the clamping hole 1051, during the process that the fastening member 102 rotates relative to the main member 101 to be clamped on the first end 1011, the clamping rod 1050 can be retracted to the fastening member 102 manually or by making the outer periphery of the guide section 1050a abut against the surface of the main member 101, so as to prevent the clamping rod 1050 from hindering the fastening process of the fastening member 102 and the main member 101. When the fastening member 102 rotates to be clamped on the main member 101, the clamping rod 1050 is aligned with the clamping hole 1051, and the clamping rod 1050 is elastically reset to extend out of the fastening member 102 and penetrate and be clamped in the clamping hole 1051, so that the fastening member 102 can be maintained in the position of being clamped on the main member 101 by the clamping rod 1050 and the clamping hole 1051 being clamped together.

[0050] Preferably, when the clamping rod 1050 is elastically reset to extend out of the fastening member 102 and penetrate and engage in the clamping hole 1051, the guide section 1050a of the clamping rod 1050 can partially extend out of the clamping hole 1051, so that part of the non-guide section 1050a of the clamping rod 1050 can enter the clamping hole 1051, so that when the clamping rod 1050 is not subjected to the action of pressing external force, the hole wall of the clamping hole 1051 cannot directly abut against the outer peripheral surface of the guide section 1050a, so as to guide the clamping rod 1050 to contract, thereby preventing the clamping rod 1050 from automatically detaching from the clamping hole 1051, and preventing the clamping relationship between the fastening member 102 and the main member 101 from being automatically released.

[0051] At this time, when it is necessary to release the fastening relationship between the fastening piece 102 and the main body 101, the operator can manually press the locking rod 1050 so that the part of the locking rod 1050 located in the locking hole 1051 is the guide section 1050a, and then rotate the fastening piece 102 so that the outer peripheral surface of the guide section 1050a abuts against the hole wall of the locking hole 1051, and then in the process of continuing to rotate the fastening piece 102, a force is applied to the outer peripheral surface of the guide section 1050a through the hole wall of the locking hole 1051 to guide the contraction of the locking rod 1050, so that the locking rod 1050 can be detached from the locking hole 1051 so as to be able to contact the fastening relationship between the fastening piece 102 and the main body 101.

[0052] In other embodiments, the first clamping structure may further include a clamping hole 1051 , and the second clamping structure may further include a clamping rod 1050 .

[0053] Optionally, the buckling member 102 can be provided with a gear 1040, and the main body 101 can be rotatably provided with a clamping strip 1041, and one end of the buckling member 102 can be provided with a first clamping structure, and the first end 1011 can be provided with a second clamping structure, so that the buckling connection between the buckling member 102 and the first end 1011 is more stable.

[0054] Optionally, the main body 101 has a first setting groove 1015 that passes through two opposite side surfaces, the buckle 102 has opposite buckle ends 1020 and an operating end 1021, and the middle portion of the buckle 102 can be rotatably arranged in the first setting groove 1015. When the operating end 1021 is located outside the first setting groove 1015, the buckle end 1020 is separated from the first end 1011. When the operating end 1021 is located inside the first setting groove 1015, the buckle end 1020 is buckled and connected to the first end 1011, so that the operator can press or pull the operating end 1021 to open the first setting groove 1015. 1, so that the fastening member 102 rotates relative to the main body 101, thereby making the fastening end 1020 close to the first end 1011 to be fastened with the first end 1011, or making the fastening end 1020 away from the first end 1011 to be in contact with the first end 1011. Compared with allowing the operator to directly operate the fastening end 1020, this configuration can prevent the operator from directly contacting the fastening end 1020, so as to prevent the operator from contacting the wire 2 near the fastening end 1020, which can improve the operating safety and prevent the operator from directly damaging the wire 2.

[0055] Preferably, the distance between the operating end 1021 and the place where the fastening member 102 is rotatably connected to the main body 101 is greater than the distance between the fastening end 1020 and the place where the fastening member 102 is rotatably connected to the main body 101, so that the principle of leverage can be utilized to enable the operator to press or pull the operating end 1021 to bring the fastening end 1020 closer to the first end 1011 to fasten with the first end 1011, or to move the fastening end 1020 away from the first end 1011 to contact and fasten with the first end 1011 more labor-saving operation.

[0056] When a groove 1013 is provided on the surface of the main body 101 as described in the aforementioned technical solution, optionally, the first setting groove 1015 can be connected to the groove 1013 so that the gear 1040 provided on the snap-fitting member 102 can at least partially extend to be located in the groove 1013.

[0057] Optionally, the spacing connection structure 11 includes two quick-release connectors 111, and the two quick-release connectors 111 are respectively arranged at the two second ends 1012. The two quick-release connectors 111 can be detachably connected along one direction, so that the connection and separation operations of the two quick-release connectors 111 are relatively simple, which can make the operation of connecting or separating the two line connection structures 10 through the two quick-release connectors 111 simpler.

[0058] The quick-release connector 111 may be of various structures. For example, the two quick-release connectors 111 may be detachably connected along the relative directions of the two quick-release connectors 111 by means including but not limited to snap connection, magnetic connection, bonding, etc.

[0059] Please combine Figure 6 As shown, optionally, a second elastic member 112 is connected between the quick-release connector 111 and the second end 1012. When the two quick-release connectors 111 are connected, the second elastic member 112 can apply an elastic force to the quick-release connector 111 and the second end 1012, so that the two second ends 1012 have a tendency to be relatively close to each other. Therefore, on the one hand, a certain elastic force can be applied to the two second ends 1012 by the second elastic member 112, so that the two second ends 1012 are easy to maintain in the current position, thereby making it easier to maintain the relative position of the two second ends 1012 in a relatively stable state. On the other hand, when the second end 1012 is acted upon by an external force, the second elastic member 112 can absorb a certain force applied by the second end 1012 to form a buffer, thereby reducing the displacement amplitude of the second end 1012, so that the relative position of the second end 1012 can be maintained in a more stable state.

[0060] Optionally, the main body 101 is provided with a second setting groove 1016 adjacent to the second end 1012, the second setting groove 1016 passes through two opposite side surfaces of the main body 101, the quick-release connector 111 includes a middle portion 1110 and two connecting portions 1111, the middle portion 1110 is located in the second setting groove 1016 and connected to the second end 1012, the two connecting portions 1111 are respectively connected to two opposite sides of the middle portion 1110, and the two connecting portions 1111 both extend out of the side surface of the main body 101 and face Extending in a direction away from the first end 1011 to protrude from the second end 1012, the connecting portions 1111 of the two quick-release connectors 111 can correspond one to one and be detachably connected along one direction, so that the two connecting portions 1111 can be respectively connected to the two connecting portions 1111 of the other quick-release connector 111 from two opposite sides of the main body 101, so that when the two quick-release connectors 111 are connected, the connection stability of the two quick-release connectors 111 is better, and the overall force of the spacer device 1 is more reasonable and balanced.

[0061] When the second elastic member 112 is connected between the quick-release connector 111 and the second end 1012 as described in the above technical solution, the second elastic member 112 may be connected between the middle portion 1110 and the second end 1012 .

[0062] Please combine Figure 7 As shown, optionally, the spacing connection structure 11 includes an insulating connector 113, and the two opposite ends of the insulating connector 113 are detachably connected to the two second ends 1012 along one direction, so that on the one hand, the insulation between the two parallel wires 2 can be enhanced by the insulating connector 113, and on the other hand, the connection and disassembly operations of the insulating connector 113 and the second end 1012 can be simple.

[0063] Optionally, the second end 1012 is provided with a slide groove 1012a, and the two opposite ends of the insulating connector 113 are provided with a slide protrusion 1130. Along the relative direction perpendicular to the two second ends 1012, the slide protrusion 1130 can be slidably connected to the slide groove 1012a, so that after the slide groove 1012a is matched and connected with the slide protrusion 1130, it is not easy for the insulating connector 113 to be detached from the second end 1012 due to the two second ends 1012 being close to or away from each other.

[0064] Optionally, the insulating member may include an insulating rod and a plurality of insulating caps disposed on the insulating rod, wherein the plurality of insulating caps are arranged at intervals along an extension direction of the insulating rod.

[0065] Optionally, a first locking hole is provided on the groove wall surface of the slide groove 1012a, and a second locking hole is provided on the sliding protrusion 1130 corresponding to the first locking hole. The spacing connection structure 11 also includes a locking pin 114, which is detachably inserted into the first locking hole and the second locking hole to lock the sliding protrusion 1130 with the second end 1012, thereby further avoiding the problem of the sliding protrusion 1130 and the second end 1012 loosening during the use of the spacing device 1.

[0066] In an optional example, the extension direction of the first locking hole and the second locking hole forms an angle with the relative sliding direction of the sliding protrusion 1130 and the sliding groove 1012a, so that when the locking pin 114 is simultaneously passed through the first locking hole and the second locking hole, the sliding protrusion 1130 can be locked with the second end 1012.

[0067] In another optional example, the locking pin 114 may be screwed into the first locking hole or the second locking hole, or the locking pin 114 may be screwed into both the first locking hole and the second locking hole to lock the sliding protrusion 1130 with the second end 1012 .

[0068] Optionally, the surface of the first end 1011 or the fastening piece 102 for forming the hole wall for accommodating the through hole 103 is provided with an elastic pad 1030, or the surfaces of the first end 1011 and the fastening piece 102 for forming the hole wall for accommodating the through hole 103 are respectively provided with elastic pads 1030, so that a buffer can be formed by the elastic pad 1030, so as to avoid excessive clamping force applied to the wire 2 by the first end 1011 and the fastening piece 102 on the one hand, and on the other hand, an elastic clamping force can be applied to the wire 2 through the elastic pad 1030, so that the first end 1011 and the fastening piece 102 can clamp the wire 2 more firmly.
