Description

Technical Field

[0001] The invention relates to a cable hanger, in particular to a double-locking cable hanger. Background Art

[0002] The currently known cable hanger structure mainly includes a cable support seat and a semicircular clamp provided on the support seat. The upper end surface of the cable support seat is a semicircular cavity for accommodating and supporting the cable. The cable is clamped in the cable support seat by a semicircular clamp or a spring clip. The disadvantages of this structure are: (1) If the diameter of the cable is small, the cable cannot be fixed by the semicircular clamp and the cable support seat. When subjected to external force, the cable is prone to shaking and wear; (2) When the spring clip is used to lock the cable, a slot that matches the spring clip needs to be provided on the cable support seat. Due to the manufacturing accuracy and the deformation of the spring clip during transportation, the locking degree is not enough, and the spring clip will be detached after a certain degree of vibration.

[0003] In addition, during the cable installation process, due to the small overall bending radius of the cable, the differences in the flatness of the wall or other installation surfaces, and the differences in installation accuracy, the parallelism between the cable hangers cannot be completely consistent, making it difficult to place the cables on some cable hangers, and the cables need to be pulled hard and bent additionally for installation.

[0025] The upper layer of the retaining spring 2 and the lower layer of the retaining spring 3 have the same structure. Figure 3 As shown, each includes a pair of arc-shaped bodies 21 that are arranged in parallel and recessed upwards, one end of the two arc-shaped bodies 21 is connected by a clamping shaft 22 that can be embedded in the upper clamping groove 112 or the lower clamping groove 114, and the other end of the two arc-shaped bodies 21 is respectively provided with a rotating shaft 23 that can be embedded in the upper clamping spring hinge hole 113 or the lower clamping spring hinge hole 111. Of course, those skilled in the art should understand that, generally, the upper clamping spring needs to be slightly larger than the lower clamping spring.

[0026] The lower clamping spring 3 can be hinged to the lower arc support plate 11 by inserting the rotating shaft at the other end into the lower clamping spring hinge hole 111 of the lower arc support plate 11, and can be connected to the lower arc support plate 11 by inserting the clamping shaft at one end into the lower clamping groove 114.

[0028] When installing the cable, first open the upper and lower retaining springs, place the cable in the recessed area of ​​the lower arc-shaped support plate, then embed the retaining shaft of the lower retaining spring into the lower retaining groove, and then embed the retaining shaft of the upper retaining spring into the upper retaining groove to achieve double locking.

[0029] Embodiment 2

[0030] The structure and connection method of this embodiment are basically the same as those of the first embodiment, including a cable support seat 1, on which is provided a lower arc-shaped support plate 11 which is recessed downward and used to accommodate cables, and a side mounting plate 12 which is used to connect to the wall, the side mounting plate 12 is connected to the lower arc-shaped support plate 11 through an upper connecting plate 13 and a lower connecting plate 14, and the upper layer of the clip spring 2 and the lower layer of the clip spring 3 are installed on the lower arc-shaped support plate 11. The difference is that the lower arc-shaped support plate 11 is not completely fixed on the cable support seat 1, but is movably and limitedly installed thereon.

[0031] The specific plan is: Figure 4 , 5 As shown, the upper connecting plate 13 is arranged downwardly at an angle from the side mounting plate side to the lower arc-shaped supporting plate side, and the lower connecting plate 14 is arranged upwardly at an angle from the side mounting plate side to the lower arc-shaped supporting plate side. The inner end of the upper connecting plate 13 is connected to the upper part of the side mounting plate, the inner end of the lower connecting plate 14 is connected to the lower part of the side mounting plate 12, and the outer end of the upper connecting plate 13 is connected to the outer end of the lower connecting plate 14.

[0032] The lower upper surface of the upper connecting plate 13 is symmetrically bent inward on both sides to form an inverted T-shaped guide groove 131; and the outer end of the lower connecting plate 14 has an extended limiting section extending along its own long axis direction and extending to the top of the inverted T-shaped guide groove 131, and the surface of the extended limiting section facing the upper connecting plate 13 is provided with a lower arc-shaped protrusion 141 and an upper arc-shaped protrusion 142 with the same structure from bottom to top, and the protruding directions of the upper arc-shaped protrusion 141 and the lower arc-shaped protrusion 142 are parallel to the extension direction of the inverted T-shaped guide groove 131, and the lower arc-shaped protrusion 142 is opposite to and extends into the inverted T-shaped guide groove 131, and the upper arc-shaped protrusion 141 is located above the inverted T-shaped guide groove 131.

[0033] like Figures 6 to 10 As shown, the lower arc-shaped support plate 11 can be movably mounted on the upper connecting plate 13: the bottom of the lower arc-shaped support plate 11 is connected to an inverted T-shaped slider 15 which can be embedded in the inverted T-shaped guide groove, and the inverted T-shaped slider 15 has an upper connecting body 151 and a lower slider body 152, the upper connecting body 151 of the inverted T-shaped slider 15 is a cylinder, and the outer diameter of the upper connecting body 151 is consistent with the width of the upper groove of the inverted T-shaped guide groove 131, and the lower slider body 152 is a rectangular parallelepiped, and a lower arc-shaped groove that can cooperate with the lower arc-shaped protrusion 141 is provided on the side edge of the rectangular parallelepiped facing the lower arc-shaped protrusion, and a gap of 1~1.5mm exists between the two side edges of the rectangular parallelepiped facing the side wall of the inverted T-shaped groove and the side wall of the lower groove of the inverted T-shaped groove; an upper arc-shaped groove that cooperates with the upper arc-shaped protrusion 142 is also opened on the surface of one side of the lower arc-shaped support plate 11.

[0034] After the lower arc support plate 11 is installed in the inverted T-shaped guide groove 131 inclined downward through the inverted T-shaped slider 15, it slides to the bottom of the inverted T-shaped guide groove under the action of gravity, so that the lower arc groove of the upper and lower slider bodies of the inverted T-shaped slider 15 is in close contact with the lower arc protrusion. At this time, the upper arc groove of the lower arc support plate 11 is just in close contact with the upper arc protrusion. Due to the control of the gap between the lower slider body 152 and the side wall of the lower groove of the inverted T-shaped groove, the inverted T-shaped slider 15 can rotate a certain angle in the inverted T-shaped groove, thereby changing the direction of its upper and lower arc support plates, and can be combined with the movement of the lower arc support plate in the inverted T-shaped guide groove of the upper connecting plate to ensure smooth installation of the cable while reducing the impact of vibration; at the same time, under the action of gravity, through the cooperation of the upper and lower arc grooves and the upper and lower arc protrusions, the rotation is well supported and guided, reducing wear and extending the service life.
