Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable installation technology, and specifically to a support frame for cable installation. Background Technology
[0002] In scenarios such as power construction, communication cabling, and factory equipment installation, cables often need to be laid and secured over long distances. To ensure the stability and safety of cables during installation, support frames are typically used to support and secure them.
[0003] CN222423115U discloses a support frame for cable installation. By disengaging the positioning rod from the slot, the movable seat can be controlled to move up and down within the slide rod, improving the convenience of vertical adjustment and enabling the support plate to be placed in different positions. Furthermore, the connection between the arc-shaped support plate and the turning support plate facilitates support for the cable when it passes through corners, improving the cable's support strength and enabling support even at corners.
[0004] The aforementioned existing technology has the following problems:
[0005] While the combination of curved support plates and turning support plates can provide some support for cables at corners, their fixed-angle design means the bending angle of the cable at the corner cannot be flexibly adjusted according to the actual needs of the construction site. This forces construction workers to force cables to conform to fixed corners in complex cabling environments, which can easily cause wear on the cable sheath, excessively small bending radius, or even internal damage. This not only affects the cable's lifespan but also hinders later maintenance and adjustments. Utility Model Content
[0006] The purpose of this utility model is to provide a support frame for cable installation, which solves the problem that the corner support angle is fixed and cannot be flexibly adjusted in the prior art, resulting in easy damage to cables and insufficient adaptability to wiring.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A support frame for cable mounting includes:
[0009] The base is equipped with vertically arranged positioning posts;
[0010] At least one cable mounting assembly, including a height adjustment element and a cable fixing element;
[0011] The height adjustment component is mounted on the positioning post;
[0012] The cable fixing component includes a supporting half-tube, a rotating component, and a limiting component;
[0013] The number of the supporting half-tubes is two; the two supporting half-tubes are set horizontally and at an angle to each other, and are used to support the cable;
[0014] The limiting component is provided on the supporting half-tube and is used to limit the cable.
[0015] The rotating component is vertically disposed on the periphery of the supporting half-tube and is rotatably connected to the height adjusting component so that the supporting half-tube can rotate and adjust its angle as the rotating component rotates.
[0016] A further technical solution is that the rotating component includes a rotating shaft, a gear, and a locking part; the rotating shaft is arranged vertically, and its lower end is rotatably mounted on the height adjusting component; the upper end of the rotating shaft is fixedly mounted on the periphery of the supporting half-tube; the gear is fixedly sleeved on the rotating shaft and located between the height adjusting component and the supporting half-tube; the gear is exposed on the side of the height adjusting component, and the locking part is used to engage with adjacent teeth of the gear.
[0017] A further technical solution is that the locking part includes a locking tube, a first spring damper, and a locking rod; the locking tube is vertically disposed on the height adjusting member; the locking rod is slidably disposed vertically inside the locking tube through the first spring damper; the upper end of the locking rod is exposed outside the locking tube and between adjacent locking teeth of the gear.
[0018] A further technical solution is that the number of limiting components is two; each limiting component includes a limiting strip, a clamping strip, and a second spring damper; the two limiting strips are disposed on the top side of the supporting half-tube and are arranged symmetrically; each of the two limiting strips has a limiting groove on its opposite sidewall; the clamping strip is slidably disposed in the limiting groove through the second spring damper; the two clamping strips are exposed outside the limiting groove under the action of the second spring damper and press the cable inside the supporting half-tube.
[0019] A further technical solution is that the upper part of the clamping strip is provided with a guide slope; the cable pressing the guide slope can drive the clamping strip to slide into the limiting groove.
[0020] A further technical solution is that the lower part of the clamping strip is provided with a limiting arc surface that fits against the cable.
[0021] A further technical solution is that the height adjustment component includes two semi-circular clamps that are detachably connected by bolts.
[0022] A further technical solution is that one of the semi-circular clamps is provided with two fixing blocks; the fixing blocks have rotating grooves; the lower end of the rotating component is coaxially rotatably disposed in the rotating grooves.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] The cable fixing component consists of two support half-tubes arranged at an angle. Cables can be placed inside the two support half-tubes and secured by limiting components. Rotating components are located on the periphery of each support half-tube and are rotatably connected to height adjustment components, allowing the support half-tubes to switch between different angles. When the cable needs to turn during installation, the angle between the two support half-tubes can be adaptively adjusted by adjusting the rotating components to meet the installation requirements of different corner angles. This solution overcomes the limitations of fixed corner support angles in existing technologies, providing flexible and adjustable support angles. This avoids cable sheath wear or excessively small bending radii caused by forced wiring, thus extending the cable's service life. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] Example:
[0033] like Figures 1-4As shown, this utility model provides a support frame for cable installation, including a base 1 and at least one cable 17 installation assembly (two are used as an example in this embodiment); the base 1 is provided with a vertically arranged positioning post 2; the cable 17 installation assembly includes a height adjustment component 3 and a cable fixing component; the height adjustment component 3 is provided on the positioning post 2; the cable 17 fixing component includes a support half-tube 4, a rotating component and a limiting component; the number of support half-tubes 4 is two; the two support half-tubes 4 are arranged horizontally and at an angle to each other, specifically, at a 90° angle; the support half-tubes 4 are used to support the cable 17; the limiting component is provided on the support half-tubes 4 and is used to limit the cable 17; the rotating component is vertically arranged on the periphery of the support half-tubes 4 and is rotatably connected to the height adjustment component 3 so that the support half-tubes 4 can rotate and adjust the angle with the rotating component.
[0034] The principles and beneficial effects of the above technical solution:
[0035] Since the cable 17 fixing component consists of two support half-tubes 4 arranged at an angle, the cable 17 can be placed in each of the two support half-tubes 4 and fixed by limiting components. Rotating components are provided around the periphery of the support half-tubes 4, and these rotating components are rotatably connected to the height adjustment component 3, allowing the support half-tubes 4 to switch between different angles with the rotating components. When the cable 17 needs to turn during installation, the angle between the two support half-tubes 4 can be adaptively adjusted by adjusting the rotating components to meet the installation requirements of different corner angles. This solution overcomes the limitation of fixed corner support angles in existing technologies, making the support angle flexible and adjustable, thereby avoiding the problems of cable 17 sheath wear or excessively small bending radius caused by forced wiring, and extending the service life of the cable 17.
[0036] In this embodiment, the rotating component includes a rotating shaft 5, a gear 6, and a locking part; the rotating shaft 5 is arranged vertically, and its lower end is rotatably mounted on the height adjusting component 3; the upper end of the rotating shaft 5 is fixedly mounted on the periphery of the supporting half-tube 4; the gear 6 is fixedly sleeved on the rotating shaft 5 and located between the height adjusting component 3 and the supporting half-tube 4; the gear 6 is exposed on the side of the height adjusting component 3, and the locking part is used to engage between adjacent teeth of the gear 6.
[0037] The principles and beneficial effects of the above technical solution:
[0038] The gear 6 engages with the locking part, allowing it to engage between two pre-defined adjacent teeth. This enables the angle of the supporting half-tube 4 to be locked in stages, thereby adjusting the corner support angle of the cable 17 and preventing damage caused by the cable 17 being forcibly bent due to a fixed angle.
[0039] In this embodiment, the snap-fit part includes a snap-fit tube 7, a first spring damper (not shown in the figure), and a snap-fit rod 8; the snap-fit tube 7 is vertically disposed on the height adjustment member 3; the lower end of the snap-fit rod 8 is slidably disposed vertically inside the snap-fit tube 7 through the first spring damper; the lower end of the first spring damper is fixed to the inner wall of the snap-fit tube 7; the upper end of the snap-fit rod 8 is exposed outside the snap-fit tube 7 and between adjacent snap-fit teeth of the gear 6.
[0040] The principles and beneficial effects of the above technical solution:
[0041] The locking rod 8 can slide vertically under the action of the first spring damper, and its upper end can automatically engage between adjacent teeth of the gear 6, thereby positioning the rotation angle of the rotating shaft 5. By utilizing the elastic reset capability provided by the first spring damper, the locking rod 8 can automatically skip teeth and reposition itself when the gear 6 rotates, achieving convenient operation and reliable positioning, and ensuring the stability of the support angle of the cable 17.
[0042] In this embodiment, there are two limiting components; the limiting components include a limiting strip 9, a pressing strip 10, and a second spring damper (not shown in the figure); the two limiting strips 9 are located on the top side of the supporting half-tube 4 and are arranged symmetrically; each of the two limiting strips 9 has a limiting groove 11 on its opposite sidewall; the pressing strip 10 is slidably disposed in the limiting groove 11 through the second spring damper; the two pressing strips 10 are exposed outside the limiting groove 11 under the action of the second spring damper and press the cable 17 in the supporting half-tube 4; the upper part of the pressing strip 10 is provided with a guide slope 12; the cable 17 pressing the guide slope 12 can drive the pressing strip 10 to slide into the limiting groove 11; the lower part of the pressing strip 10 is provided with a limiting arc surface 13 that fits with the cable 17.
[0043] The principles and beneficial effects of the above technical solution:
[0044] The limiting component employs two symmetrically arranged limiting strips 9, each with a limiting groove 11. The abutting strip 10 extends outward under the action of a second spring damper, contacts the cable 17 via the guide ramp 12, and slides into the limiting groove 11, ultimately causing the limiting arc surface 13 to conform to the cable 17. This allows the cable 17 to be automatically pressed in and fixed by the limiting arc surface 13 during installation, avoiding repeated manual adjustments and ensuring the stability and flexible buffering of the limiting mechanism, preventing wear on the cable 17's outer sheath.
[0045] In this embodiment, the height adjustment component 3 includes two semi-circular clamps 15 that are detachably connected by bolts 14; one of the semi-circular clamps 15 is provided with two fixing blocks 16; the fixing blocks 16 have a rotating groove (not shown in the figure); the lower end of the rotating shaft 5 is coaxially rotatably disposed in the rotating groove; the clamping tube 7 is vertically disposed on the side wall of the fixing block 16.
[0046] The principles and beneficial effects of the above technical solution:
[0047] The height adjustment component 3 consists of two semi-circular clamps 15, which are detachably connected together by bolts 14 and can be fitted onto the positioning post 2. One of the semi-circular clamps 15 has a fixing block 16, which has a slot for mounting the lower end of the rotating shaft 5. A retaining tube 7 is also installed on its side wall. The height adjustment component 3 not only allows for height adjustment of the entire supporting half-tube 4 on the positioning post 2, but also provides a rotation fulcrum through the combination of the slot and the rotating shaft 5. Combined with the retaining tube 7 and the retaining part, it further enhances the flexibility and stability of the cable 17 support angle adjustment.

More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
