Description

Technical Field

[0001] The utility model relates to the technical field of wire clamps, in particular to a tension-resistant wire clamp for parallel household lines. Background Art

[0002] A tension clamp is a metal fitting used to fix the conductor to withstand the conductor tension and hang the conductor on a tension string or pole tower.

[0003] Strain clamps can be roughly divided into two categories according to their structure and installation conditions. The first category: The strain clamp must withstand the full tensile force of the conductor or lightning conductor. The clamp's gripping force must not be less than 90% of the rated tensile strength of the installed conductor or lightning conductor, but it does not serve as a conductor. This type of clamp can be removed after the conductor is installed and used separately. This type of clamp includes bolt-type strain clamps and wedge-type strain clamps. The second category: In addition to bearing the full tensile force of the conductor or lightning conductor, the strain clamp also serves as a conductor. Therefore, once this type of clamp is installed, it cannot be disassembled and is also called a dead wire clamp. Since it is a conductor, the installation of the clamp must comply with the relevant installation operating procedures and be carried out carefully.

[0004] The wires on the outer wall of a house are called service lines. Parallel wire clamps are commonly used for service line tension clamps, and they need to be easy to disassemble and assemble for house decoration or rural wiring. The applicant has designed a parallel service line tension clamp, which is improved on the basis of the original single-wire tension clamp so that it can be used as a double-wire parallel wire clamp. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and provide a parallel household line tension clamp. The technical solutions adopted by this utility model are as follows:

[0006] A parallel subscriber line tension clamp comprises a base plate and a first clamp and a second clamp arranged on the base plate, wherein two parallel lower receiving grooves for cables to pass through are provided on the base plate, the hinged parts of the first clamp and the second clamp are close to each other and hinged, and the ends of the first clamp and the second clamp that are away from each other can be opened toward both sides of the base plate to adjust the distance between the clamp and the lower receiving groove respectively, and the first clamp and the second clamp are detachably connected to the base plate by bolts; the first clamp and the second clamp have upper clamping jaws at positions facing both sides of the base plate, and the upper clamping jaws cross-match with the lower clamping jaws on both sides of the base plate.

[0007] When the cable is not clamped, the first and second clamps are initially connected to the base plate by bolts and are not separated. The bolts are not tightened. The first clamp and the second clamp can be opened in a limited range to adjust the distance between any clamp and the lower receiving groove for the cable to pass through. Since the first clamp and the second clamp can be adjusted separately, the positioning can be adjusted one by one when threading. After the threading is completed, the bolts are tightened, the first and second clamps are clamped relative to the base plate, the upper and lower clamping jaws are cross-locked, and the clamps and the base plate are further positioned relative to each other.

[0008] Preferably, a positioning portion is provided between the hinge portion and the upper clamping jaw, and a waist-shaped hole is provided on the positioning portion for the bolt to pass through. The waist-shaped hole allows the clamp to move within a limited range relative to the bolt so as to open relative to the base plate.

[0009] Preferably, screw holes are provided on both sides of the base plate at positions corresponding to the waist-shaped holes for bolts to pass through.

[0010] Preferably, the upper clamping jaw is provided with an upper accommodating groove corresponding to the position of the lower accommodating groove, and the inner walls of the upper and lower accommodating grooves are both provided with anti-slip convex patterns.

[0011] Preferably, the hinged parts of the first clamp and the second clamp are hinged to the same hinge axis, and the first clamp and the second clamp can rotate independently relative to the hinge axis; the two ends of the hinge axis are connected and positioned with the base plate through a hinge seat, and the diameter of the through hole for the hinge axis to pass through on the hinge seat is larger than the diameter of the hinge axis, so that the first clamp or the second clamp can drive the hinge axis to move slightly in the through hole when it moves; the hinge seat is only used to make a preliminary connection between the clamps after the hinge axis passes through. Due to errors in mold matching and different cable diameters, the first clamp and the second clamp may be difficult to fit exactly with the accommodating groove on the base plate when rotating around the axis, so the movable margin of the hinge axis is designed for assembly adjustment.

[0012] Preferably, the base plate is an integrated base plate, and a positioning plate is extended from the base plate.

[0013] The beneficial effects of the present invention are as follows: when the cable is not clamped, the first and second clamps are initially connected to the base plate by bolts and are not separated. The bolts are not tightened, and the first clamp and the second clamp can be opened in a limited range on both sides to adjust the distance between any clamp and the lower accommodating groove for the cable to pass through. Since the first clamp and the second clamp can be adjusted separately, the positioning can be adjusted one by one when threading. After the threading is completed, the bolts are turned, the first and second clamps are clamped relative to the base plate, the upper and lower clamping jaws are cross-locked, and the clamps and the base plate are further positioned relative to each other; the present device has a simple structure, is easy to disassemble and assemble, and is easy to operate. When parallel wiring is performed, the positioning of a certain cable can be adjusted separately. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1

[0025] like Figure 1-5As shown, a parallel household line tension clamp includes an integrated base plate 1 and a first clamp 21 and a second clamp 22 arranged on the base plate 1, and two parallel lower accommodating grooves 11 for cables to pass through are provided on the base plate 1, and the hinge parts 4 of the first clamp 21 and the second clamp 22 are close to each other and hinged, and the ends of the first clamp 21 and the second clamp 22 away from each other can be opened toward both sides of the base plate 1 to adjust the distance between the clamp and the lower accommodating groove 11 respectively, and the first clamp 21 and the second clamp 22 are detachably connected to the base plate 1 by bolts 5; the first clamp 21 and the second clamp 22 have upper clamps 3 at the positions facing both sides of the base plate 1, and the upper clamps 3 cross-match with the lower clamps 12 on both sides of the base plate 1.

[0026] When the cable is not clamped, the first and second clamps are initially connected to the base plate by bolts and are not separated. The bolts are not tightened, and the first clamp and the second clamp can be opened in a limited range on both sides to adjust the distance between any clamp and the lower accommodating groove for the cable to pass through. Since the first clamp and the second clamp can be adjusted separately, the positioning can be adjusted one by one when threading. After the threading is completed, the bolts are turned, and the first and second clamps are clamped relative to the base plate. The upper and lower clamping jaws are cross-locked, and the clamps and the base plate are further positioned relative to each other. The device has a simple structure, is easy to disassemble and assemble, and is easy to operate. When parallel wiring is performed, the positioning of a certain cable can be adjusted separately.

[0027] A positioning portion is provided between the hinge portion 4 and the upper clamping jaw 3 , and a waist-shaped hole 51 is provided on the positioning portion for the bolt 5 to pass through. The waist-shaped hole allows the clamp to move within a limited range relative to the bolt so as to open relative to the base plate.

[0028] Screw holes are provided on both sides of the base plate 1 at positions corresponding to the waist-shaped holes 51 for the bolts 5 to pass through.

[0029] The upper clamping jaw 3 is provided with an upper accommodating groove 31 corresponding to the position of the lower accommodating groove 11 , and the inner walls of the upper and lower accommodating grooves are both provided with anti-slip convex patterns.

[0030] The hinge parts 4 of the first clamp 21 and the second clamp 22 are hinged to the same hinge shaft 41, and the first clamp 21 and the second clamp 22 can rotate independently relative to the hinge shaft 41; the two ends of the hinge shaft 41 are connected and positioned with the base plate 1 through the hinge seat 42, and the diameter of the through hole on the hinge seat 42 for the hinge shaft 41 to pass through is larger than the diameter of the hinge shaft 41, so that the first clamp 21 or the second clamp 22 can drive the hinge shaft 41 to move slightly in the through hole when it moves; the hinge seat is only used to allow the hinge shaft to pass through and make a preliminary connection to the clamps. Due to errors in mold matching and different cable diameters, the first clamp 21 and the second clamp 22 may be difficult to fit exactly with the accommodating groove 11 on the base plate when rotating around the axis. Therefore, the movable margin of the hinge shaft is designed for assembly adjustment.

[0031] Finally, a positioning plate 13 is extended from the bottom plate 1 , and the lower receiving groove 11 extends to the positioning plate 13 to guide the cables.

[0032] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
