Description

Technical Field

[0001] The present application relates to the technical field of electrical tools, and in particular to a street code tensioner. Background Art

[0002] The street tie is a device used to straighten and fix the cable when laying it. The traditional street tie consists of a hardware bracket that can be nailed to the wall (the hardware bracket includes a base that can be fixed to the wall and a bracket that can be fixed to the iron bar), a porcelain bottle for supporting the cable, and an iron bar for fixing the porcelain bottle to the hardware bracket. When the line passes through the street tie, it usually passes through the porcelain bottle, and then the cable and the porcelain bottle are tied and fixed by wrapping metal wire. This street tie is inefficient, and there is no unified standard for the bundling method and the bundling tightness. It is very arbitrary and easily leads to loose fixing of the line. It will loosen or even come off after long-term use. The metal wire is directly wrapped around the cable sheath, which will cause damage to the cable sheath, and easily cause dangers such as cable overheating or even leakage short circuit.

[0034] It should be understood that this application is applied to the field of street code, please refer to Figure 1 , Figure 1 The installation structure diagram of the street code tensioner provided in the embodiment of the present application is as follows: Figure 1 As shown, Figure 1 The invention comprises an installation body, a first connecting member 7-1, a second connecting member 7-2, a fixing member, an insulating arc member and a fastener; the first ends of the first connecting member 7-1 and the second connecting member 7-2 are aligned and fixed on the installation body, the fixing member 8 is fixed on the second ends of the first connecting member 7-1 and the second connecting member 7-2, and the insulating arc member 6 is penetrated and fixed on the fixing member 8 so that the insulating arc member 6 is placed between the first connecting member 7-1 and the second connecting member 7-2; the fastener comprises an adjusting rod 20, a shifting rod 10, an adjusting member 9, a rotating shaft 11 and an airbag assembly; the first end of the adjusting rod 20 is fixed on the installation body, the first end of the shifting rod 10 penetrates the adjusting rod 20 and is arranged at the second end of the adjusting rod 20, the third end of the adjusting rod 20 is provided with the adjusting member 9, the second end of the shifting rod 10 is rotatably connected to the first connecting member 7-1 through the rotating shaft 11, the third end of the shifting rod 10 is provided with an airbag assembly, and the airbag assembly is provided There is a gas channel, which is connected to the outside world, and the airbag assembly is aligned with the recessed area A of the insulating arc-shaped member; the cable is arranged in the recessed area A, and the adjusting member 9 adjusts the first end of the lever 10 to be fixed at the preset first position of the adjusting rod 20, and through the action of the rotating shaft 11, the airbag assembly moves in the direction close to the insulating arc-shaped member 6, so that the airbag assembly squeezes the cable, so that the cable is fixed in the recessed area A, and the gas inside the airbag assembly escapes through the gas channel; the adjusting member 9 adjusts the first end of the lever 10 to be fixed at the preset second position of the adjusting rod 20, and through the action of the rotating shaft 11, the airbag assembly moves in the direction away from the insulating arc-shaped member 6, so that the airbag assembly no longer squeezes the cable, and after the gas inside the airbag assembly escapes through the gas channel, a negative pressure is formed inside the airbag assembly, and after the airbag assembly no longer squeezes the cable, the outside air enters the airbag assembly through the gas channel, so that the airbag assembly returns to its original state.

[0035] The present application designs a street code tensioner, which fixes the installation body on the cable pole. When in use, the cable is wound around the recessed area A of the insulating arc-shaped part, and the angle of the cable is adjusted to keep the cable in a tensioned state. The adjustment member 9 fixes the lever 10 in the preset first position along the axial direction of the adjustment rod 20, and the lever 11 is used to move the airbag assembly toward the recessed area A close to the insulating arc-shaped part 6. The airbag assembly cooperates with the insulating arc-shaped part 6 to form a locking structure, so that the airbag assembly squeezes the cable, the airbag assembly is deformed, and the gas inside the airbag assembly escapes through the gas channel of the airbag assembly. The airbag assembly is in a wrinkled state, so that the airbag assembly is in a state of squeezing the cable, so that the cable is fixed in the recessed area A, and the contact area between the airbag assembly and the cable and the insulating arc-shaped part 6 is larger. The increased friction is beneficial to keeping the cable locked and preventing the cable from falling off; when disassembly is required, the adjusting member 9 is fixed to the lever 10 at the preset second position along the axial direction of the adjusting rod 20, and the lever 11 is used to move the airbag assembly in the direction of the recessed area A away from the insulating arc-shaped member 6, so that the airbag assembly no longer squeezes the cable, and the airbag assembly no longer cooperates with the insulating arc-shaped member 6 to form a locking structure, and the external air enters the interior of the airbag assembly through the gas channel, and the airbag assembly is restored; thus, the cable can be easily removed; it is more convenient to use.

[0036] The street code tensioner of the present application forms a space between the airbag assembly and the recessed area A of the insulating arc-shaped member 6, and the cable can be fixed in the recessed area A by the squeezing effect of the airbag assembly. When the airbag assembly no longer squeezes the cable, the outside air restores the airbag assembly. It can be seen that the street code tensioner of the present application is easy to disassemble, which is convenient for tightening and disassembling the cable.

[0037] The airbag assembly of the present application can be an existing commonly used airbag device. The embodiment of the present application provides a structure of a first airbag assembly. For ease of understanding, please refer to Figure 2-3 , Figure 2 This is a structural diagram of the first airbag assembly provided in an embodiment of the present application. Figure 3 for Figure 2The internal structure of the airbag. The airbag assembly includes an airbag 12, a fixing frame 21 and an arc seat 19. The airbag 12 is fixed to the inner concave surface of the arc seat 19 through the fixing frame 21, so that the arc seat 19 is half wrapped around the outer periphery of the airbag 12, and the outer convex surface of the arc seat 19 is fixed to the third end of the lever 10. Specifically, the arc seat 19 is a hollow structure, and the arc seat 19 is provided with a first air hole 15 and a through hole 14. The through hole 14 is provided on the inner concave surface. The airbag 12 is connected to the through hole 14 through the gas channel 18, so that the airbag 12 is connected to the outside through the gas channel 18, the through hole 14 and the first air hole 15. The airbag assembly squeezes the cable, causing the airbag 12 to deform, and the gas inside the airbag 12 escapes to the outside through the gas channel 18, the through hole 14 and the first air hole 15. The gas inside the airbag 12 escapes through the gas channel 18, the through hole 14 and the first air hole 15, which can better adjust the air tightness of the airbag 12 and make the airbag 12 less likely to leak.

[0038] It should be noted that after the airbag 12 of the present application is squeezed, a negative pressure is formed inside the airbag 12. When disassembly is required, the first end of the lever 10 is adjusted by the adjusting member 9 to be fixed at the preset second position of the adjusting rod 20. Through the action of the rotating shaft 11, the airbag assembly moves away from the insulating arc-shaped member 6, and the squeezing pressure on the airbag 12 gradually decreases. Since the airbag 12 is made of highly elastic material, the deformation of the airbag gradually recovers, and the external gas gradually passes through the first air vent 15, flows to the through hole 14, and is injected into the airbag 12 through the gas channel 18, until the pressure inside and outside the airbag 12 is restored to balance and the airbag 12 is restored.

[0039] It should be noted that the arc seat 19 needs to meet certain mechanical strength requirements, and the material is not limited as long as it can withstand the pressure transmitted by the airbag 12 after being squeezed.

[0040] The present application embodiment provides a second structure of the capsule assembly. For ease of understanding, please refer to Figure 4 , Figure 4 A structural diagram of the second airbag assembly provided in an embodiment of the present application. The street code tensioner of the present application also includes a buffer pad 13, the arc seat 19 is a hollow structure, the arc seat 19 is provided with a first air vent 15, the buffer pad 13 is provided with a through hole 14, the buffer pad 13 is arranged on the inner concave surface, the airbag 12 is connected with the through hole 14 of the buffer pad through the gas channel, so that the airbag 12 is connected with the outside through the gas channel, the through hole 14 of the buffer pad and the first air vent 15. Among them, the buffer pad 13 is arranged in the space between the airbag 12 and the arc seat 19, so that the buffer pad 13 prevents the airbag 12 from directly contacting the arc seat 19, and the buffer pad 13 plays a role in buffering and increasing friction.

[0041] It should be noted that the buffer pad 13 will deform to a certain extent due to its buffering function, while the arc seat 19 mainly functions as a base, requires relatively high mechanical properties, and hardly deforms.

[0042] The present application embodiment provides a third structure of the capsule assembly. For ease of understanding, please refer to Figure 5 , Figure 5 The structural diagram of the airbag of the third airbag assembly provided in the embodiment of the present application. The airbag of the present application also includes a hollow arc-shaped fixing seat 16, which is fixed inside the airbag 12, and the arc-shaped fixing seat 16 is fixed to the third end of the lever 10 through the airbag 12, and the arc-shaped fixing seat 16 is provided with an air hole 22 and a second air vent, the air hole 22 is connected to the inside of the airbag 12, and the second air vent is connected to the through hole 14. Among them, the buffer pad 13 is arranged in the space between the airbag 12 and the arc-shaped fixing seat 19, and the arc-shaped fixing seat 16 in the airbag 12 keeps the position of the airbag 12 unchanged; and the buffer pad 13 prevents the arc-shaped fixing seat 16 of the airbag 12 from directly contacting the arc-shaped fixing seat 19, and the buffer pad 13 plays a role in buffering and increasing friction.

[0043] It should be noted that the arc-shaped fixing seat 16 needs to have high mechanical strength and can be a bracket made of hard rubber or plastic connected to the arc-shaped seat. The material is not limited as long as it can withstand the air pressure generated after the airbag is squeezed. It is preferably a high-hardness metal material or a composite material.

[0044] Specifically, the arc-shaped fixing seat 16 of the embodiment of the present application is further provided with a reinforcing rib 17, and the reinforcing rib 17 is arranged inside the arc-shaped fixing seat 16. The reinforcing rib 17 is used to increase the mechanical strength of the arc-shaped fixing seat 16.

[0048] Specifically, the latch is inserted into the pin holes at different positions so that the latch can adjust the second end of the lever 10 to the position of the adjustment rod 20, and finally the latch can detachably fix the second end of the lever 10 to different positions of the adjustment rod 20.

[0049] The adjusting rod and adjusting member of the present application can be the existing commonly used adjusting rods and adjusting members that can adjust the position. The embodiment of the present application provides a third structure of the adjusting rod and the adjusting member, and the adjusting rod 20 is provided with positioning members at different positions along the axial direction. The adjusting member 9 is a fastener, and the positioning member of the adjusting rod 20 is snap-connected with the fastener.

[0050] Specifically, the above-mentioned positioning member and fastener are existing conventional devices that can be used for positioning and installation. The fastener can be snap-connected with the positioning members at different positions. Through the snap-connection between the fastener and the positioning member, the second end of the lever 10 can be detachably fixed at different positions of the adjustment rod 20.

[0051] The installation body of the present application can be an existing commonly used installation device that can be installed on a cable pole.

[0052] See also Figure 7 , Figure 7 Schematic diagram of the compressed state of the street code tensioner provided in the embodiment of the present application. When in use, the street code tensioner of the embodiment of the present application is in the compressed state. First, fix the positioning pin 1 and the locking nut 3 to the preset position of the wall or the cable pole, and then wrap the cable around the recessed area A of the insulating arc 6, so that the cable is fixed to form a space between the airbag assembly and the recessed area A of the insulating arc 6, and then fix the first end of the adjusting member 9 adjusting lever 10 to the preset first position of the adjusting rod 20 ( Figure 7 The preset first position of the adjustment rod 20 is the position where the first end of the lever 10 is close to the mounting plate 5). Through the action of the rotating shaft 11, the airbag assembly moves toward the insulating arc-shaped member 6, so that the airbag assembly squeezes the cable to fix the cable in the recessed area A, and the gas inside the airbag assembly escapes through the gas channel.

[0053] See also Figure 8 , Figure 8 Schematic diagram of the loosened state of the street code tensioner provided in the embodiment of the present application. When disassembly is required, the street code tensioner of the embodiment of the present application is in the loosened state, and the first end of the adjusting member 9 adjusting lever 10 is fixed at the preset second position of the adjusting rod 20 ( Figure 8 The preset second position of the adjustment rod 20 is the position where the first end of the lever 10 is away from the mounting plate 5). Through the action of the rotating shaft 11, the airbag assembly moves in the direction away from the insulating arc-shaped member 6, so that the airbag assembly no longer squeezes the cable.
