Description

Technical Field

[0001] This invention relates to the field of power transmission line laying technology, and more particularly to a spacing device for parallel wires. Background Technology

[0002] When laying power transmission lines that include parallel wires, spacing devices are usually used to connect the parallel wires at intervals in order to keep them parallel and avoid the risk of current breakdown and short circuit caused by them getting too close together during use.

[0003] Specifically, the spacer used in the relevant technology requires manual tightening of the threaded parts at both ends of the spacer to clamp two parallel wires at each end. Because the threaded parts are installed close to the wires, and the clamping force of the spacer on the wires is determined by the tightness of the threaded parts, it is easy for manual operation errors to cause the threaded parts to scrape against the wires, or for the clamping force of the spacer on the wires to be too large, which can easily lead to damage to the wires.

[0012] The main body is detachably connected to a cover, which can seal the groove.

[0013] As a preferred technical solution for the spacing device of the parallel wires, the main body has a first setting groove extending through two opposite sides, the fastening member has opposite fastening ends and operating ends, the middle part of the fastening member is rotatably disposed in the first setting groove, when the operating end is located outside the first setting groove, the fastening end is separated from the first end, when the operating end is located inside the first setting groove, the fastening end is fastened and connected to the first end.

[0036] 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 with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal 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 two ends of the spacing connection structure 11 are 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 including a main body 101 and a fastening member 102 that are movably connected to each other, the wiring connection structure 10 can clamp the wire 2 in the receiving 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. On the one hand, there is no need to use threaded parts near the wire 2, so as to avoid damage to the wire 2 when the wiring connection structure 10 is manually connected to the wire 2. On the other hand, the clamping force applied by the wiring connection structure 10 to the wire 2 is determined by the size of the receiving 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 wiring 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 by the spacer device 1 during use.

[0041] To improve the stability of the fastening connection between the fastening member 102 and the main body 101, various methods can be used to enhance the stability of the fastening connection between the fastening member 102 and the main body 101.

[0042] Please combine Figure 3 and Figure 4As shown, in an optional example, the fastening member 102 is provided with a gear 1040, the gear 1040 is coaxial with the rotation axis of the fastening member 102 relative to the main body 101, the main body 101 is rotatably provided with a retaining strip 1041, and a first elastic member 1042 is connected between the retaining strip 1041 and the main body 101. One side of the retaining strip 1041 can abut against the main body 101, and when one side of the retaining strip 1041 abuts against the main body 101, one end of the retaining strip 1041 extends into the gap between two adjacent teeth of the gear 1040. The retaining strip 1041 can rotate relative to the main body 101 so that the retaining strip 1041 is located on the outer periphery of the gear 1040. The first elastic member 1042 can apply an elastic force to the retaining strip 1041, so that the retaining strip 1041 has a tendency to rotate relative to the main body 101 to abut against the main body 101.

[0043] Understandably, during the process of rotating the fastening member 102 relative to the main body 101 until it engages with the first end 1011, the gear 1040 rotates in one direction relative to the main body 101 to actuate the end of the retaining strip 1041, causing the retaining strip 1041 to rotate relative to the main body 101. The first elastic member 1042 is compressed or stretched to increase the elastic restoring force applied to the fastening member 102. Once the fastening member 102 is engaged, if the gear 1040 rotates in the opposite direction, the retaining strip 1041 will... One side of 41 will abut against the main body 101, so that one end of the locking strip 1041 extending into the gap between two adjacent teeth of the gear 1040 can prevent the gear 1040 from rotating in the opposite direction of the aforementioned direction. In other words, the locking strip 1041 can limit the relative posture of the gear 1040 and the main body 101, thereby limiting 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 of being fastened to the main body 101 under the limiting effect of the locking strip 1041.

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

[0045] Optionally, the card strip 1041 may also be provided with an operating structure protruding outward toward the spacer device 1, the operating structure being used by an operator to grip and move the card strip 1041.

[0046] Please combine Figure 5As shown, optionally, the surface of the main body 101 is provided with a groove 1013, and the gear 1040 is at least partially located in the groove 1013. A retaining strip 1041 is rotatably provided in the groove 1013. The main body 101 is detachably connected to a cover 1014, which can cover the groove 1013. Thus, when there is no need to manually move the retaining strip 1041, the gear 1040 and the retaining strip 1041 in the groove 1013 can be covered by the cover 1014, so as to prevent the retaining strip 1041 from being moved due to accidental circumstances, thereby preventing the fastener 102 and the main body 101 from accidentally releasing the clamping of the wire 2.

[0047] For example, when one end of the locking bar 1041 extends into the gap between two adjacent teeth of the gear 1040, the side of the locking bar 1041 away from the gear 1040 can abut against the groove wall of the groove 1013. When the locking bar 1041 is moved relative to the main body 101 by the gear 1040 or the operator to compress the first elastic member 1042, the side of the locking bar 1041 away from the gear 1040 can move away from the groove wall of the groove 1013. Alternatively, the main body 101 may be provided with a protruding limiting block located on one side of the locking bar 1041 in the direction of rotation relative to the main body 101. When one end of the locking bar 1041 extends into the gap between two adjacent teeth of the gear 1040, one side of the locking bar 1041 abuts against the limiting block. When the locking bar 1041 is moved relative to the main body 101 by the gear 1040 or the operator to compress the first elastic member 1042, one side of the locking bar 1041 can move away from the limiting block.

[0048] Please continue to refer to this as well. Figure 2 , Figure 4 and Figure 5 In another alternative example, the fastening member 102 is used to fasten a first snap-fit ​​structure at one end of the main body member 101, and a second snap-fit ​​structure at the first end 1011. One of the first snap-fit ​​structure and the second snap-fit ​​structure includes an elastically retractable snap-fit ​​rod 1050, the top end of which has a frustum-shaped guide section 1050a. The other includes a snap hole 1051, the snap-fit ​​rod 1050 can snap into the snap hole 1051, and along the length extension direction of the snap-fit ​​rod 1050, the size of the guide section 1050a is greater than or equal to the size of the snap hole 1051.

[0049] Taking the first snap-fit ​​structure including a snap-fit ​​rod 1050 and the second snap-fit ​​structure including a snap-fit ​​hole 1051 as an example, during the process of the fastening member 102 rotating relative to the main body 101 to snap onto the first end 1011, the snap-fit ​​rod 1050 can be retracted into the fastening member 102 by manually or by having the outer periphery of the guide section 1050a abut against the surface of the main body 101, so as to avoid the snap-fit ​​rod 1050 obstructing the snap-fit ​​process between the fastening member 102 and the main body 101. When the fastening member 102 rotates to snap onto the main body 101, the snap-fit ​​rod 1050 and the snap-fit ​​hole 1051 are aligned, and the snap-fit ​​rod 1050 elastically returns to its original position, extending out of the fastening member 102 and passing through and snapping onto the snap-fit ​​hole 1051. Thus, the fastening member 102 can be maintained in the position snapped onto the main body 101 by the engagement of the snap-fit ​​rod 1050 and the snap-fit ​​hole 1051.

[0050] Preferably, when the locking rod 1050 elastically resets to extend out of the fastening member 102 and engage with the locking hole 1051, the guide section 1050a of the locking rod 1050 can partially extend out of the locking hole 1051, so that a portion of the non-guide section 1050a of the locking rod 1050 can enter the locking hole 1051. Thus, when the locking rod 1050 is not subjected to external pressing force, the wall of the locking hole 1051 cannot directly abut against the outer peripheral surface of the guide section 1050a, thereby guiding the locking rod 1050 to retract. This prevents the locking rod 1050 from automatically disengaging from the locking hole 1051, thus preventing the fastening relationship between the fastening member 102 and the main body 101 from automatically disengaging.

[0051] At this time, when it is necessary to release the fastening relationship between the fastener 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. Then, rotate the fastener 102 so that the outer peripheral surface of the guide section 1050a abuts against the hole wall of the locking hole 1051. Then, as the fastener 102 continues to rotate, the hole wall of the locking hole 1051 applies a force to the outer peripheral surface of the guide section 1050a to guide the locking rod 1050 to retract, so that the locking rod 1050 can disengage from the locking hole 1051 and can contact the fastener 102 and the main body 101.

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

[0053] Optionally, the fastening member 102 may be provided with a gear 1040, and the main body 101 may be rotatably provided with a locking strip 1041. At the same time, one end of the fastening member 102 may be provided with a first locking structure, and the first end 1011 may be provided with a second locking structure, so as to improve the fastening connection stability between the fastening member 102 and the first end 1011.

[0054] Optionally, the main body 101 has a first mounting groove 1015 extending through two opposite sides, and the fastening member 102 has a fastening end 1020 and an operating end 1021. The middle part of the fastening member 102 is rotatably disposed within the first mounting groove 1015. When the operating end 1021 is located outside the first mounting groove 1015, the fastening end 1020 is separated from the first end 1011. When the operating end 1021 is located inside the first mounting groove 1015, the fastening end 1020 is fastened and connected to the first end 1011, so that the operator can press or pull the operating end 102. 1. To allow the fastening member 102 to rotate relative to the main body 101, thereby causing the fastening end 1020 to move closer to the first end 1011 to engage with the first end 1011, or to move the fastening end 1020 away from the first end 1011 to engage with the first end 1011. Compared to allowing the operator to directly operate the fastening end 1020, this setting can avoid the operator directly contacting the fastening end 1020, thus avoiding the operator contacting the wire 2 near the fastening end 1020, improving operational safety, and preventing the operator from directly damaging the wire 2.

[0055] Preferably, the distance between the operating end 1021 and the fastening member 102 rotatably connected to the main body 101 is greater than the distance between the fastening end 1020 and the fastening member 102 rotatably connected to the main body 101. This allows the lever principle to be utilized, making it easier for the operator to press or pull the operating end 1021 to bring the fastening end 1020 closer to the first end 1011 for fastening, or to move the fastening end 1020 away from the first end 1011 for contact and fastening.

[0056] When the surface of the main body 101 is provided with a groove 1013 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 fastening member 102 can at least partially extend into the groove 1013.

[0057] Optionally, the spaced connection structure 11 includes two quick-release connectors 111, which are respectively disposed on two second ends 1012. The two quick-release connectors 111 can be detachably connected in one direction, so the connection and disconnection operations of the two quick-release connectors 111 are relatively simple, making it easier to connect or disconnect the two line connection structures 10 through the two quick-release connectors 111.

[0058] The quick-release connector 111 can have various different structures. For example, two quick-release connectors 111 can be detachably connected along their relative directions by means including but not limited to snap-fit, magnetic connection, and adhesive.

[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, causing the two second ends 1012 to tend to move closer together. Thus, on the one hand, the second elastic member 112 can apply a certain elastic force to the two second ends 1012, making it easier for the two second ends 1012 to be kept in their current position, and thus making it easier for the relative position of the two second ends 1012 to be kept in a more stable state. On the other hand, when the second end 1012 is subjected to an external force, the second elastic member 112 can absorb a certain force applied by the second end 1012 to form a buffer, reduce the displacement amplitude of the second end 1012, and make the relative position of the second end 1012 be kept in a more stable state.

[0060] Optionally, the main body 101 is provided with a second mounting groove 1016 adjacent to the second end 1012. The second mounting groove 1016 extends through two opposite sides 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 mounting 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. Both connecting portions 1111 extend out of the side of the main body 101 and face towards... Extending away from the first end 1011 to protrude from the second end 1012, the connecting parts 1111 of the two quick-release connectors 111 can correspond one-to-one and be detachably connected in one direction. Thus, the two connecting parts 1111 can be connected from the two opposite sides of the main body 101 to the two connecting parts 1111 of the other quick-release connector 111. This makes the connection stability of the two quick-release connectors 111 better when they are connected, and the overall force of the spacer 1 is more reasonable and balanced.

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

[0062] Please combine Figure 7 As shown, optionally, the spaced connection structure 11 includes an insulating connector 113. The two opposite ends of the insulating connector 113 are detachably connected to the two second ends 1012 in one direction, thereby enhancing the insulation between the two parallel wires 2 through the insulating connector 113, and simplifying the connection and disconnection of the insulating connector 113 and the second ends 1012.

[0063] Optionally, the second end 1012 is provided with a groove 1012a, and both opposite ends of the insulating connector 113 are provided with sliding protrusions 1130. The sliding protrusions 1130 are slidably connected to the groove 1012a in a direction perpendicular to the opposite direction of the two second ends 1012. Thus, after the groove 1012a and the sliding protrusions 1130 are connected, the insulating connector 113 is not easily disengaged from the second end 1012 due to the two second ends 1012 getting closer or further apart.

[0064] Optionally, the insulating element may include an insulating rod and a plurality of insulating caps disposed on the insulating rod, the plurality of insulating caps being spaced apart along the extension direction of the insulating rod.

[0065] Optionally, the groove wall of the slide 1012a is provided with a first locking hole, and the slide protrusion 1130 is provided with a second locking hole corresponding to the first locking hole. The spacer 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 slide protrusion 1130 and the second end 1012, thereby further preventing the slide protrusion 1130 from becoming loose from the second end 1012 during the use of the spacer device 1.

[0066] In one alternative example, the extending directions of the first locking hole and the second locking hole form an angle with the relative sliding directions of the sliding protrusion 1130 and the sliding groove 1012a, so that when the locking pin 114 is simultaneously inserted into the first locking hole and the second locking hole, it can lock the sliding protrusion 1130 and the second end 1012.

[0067] In another alternative 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 simultaneously to lock the sliding protrusion 1130 to the second end 1012.

[0068] Optionally, the surface of the first end 1011 or the fastener 102 used to form the hole wall for receiving the through hole 103 is provided with an elastic pad 1030. Alternatively, the surfaces of the first end 1011 and the fastener 102 used to form the hole wall for receiving the through hole 103 are both provided with elastic pads 1030. This allows the elastic pads 1030 to form a buffer, thereby preventing the clamping force applied to the wire 2 by the first end 1011 and the fastener 102 from being too large. On the other hand, the elastic pads 1030 can apply an elastic clamping force to the wire 2, so that the first end 1011 and the fastener 102 can clamp the wire 2 more securely.
