Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically a foldable cable trench support. Background Technology

[0002] In power and telecommunications engineering, cable trench supports are key components for supporting cable laying. Traditional cable trench supports are mostly fixed structures, which have the following technical drawbacks: the supports are large and heavy, occupying a lot of space during transportation and are easily damaged. Installation requires on-site assembly and debugging, which is difficult and inefficient for manual operation, especially in cable trench construction in narrow or complex terrain. The support base is usually at a fixed height, making it difficult to adapt to uneven or sloping ground environments, which can lead to uneven stress on the supports, poor stability, and the risk of cables falling. The cable support structure is usually a fixed groove, which cannot adjust the limiting space according to the cable diameter and lacks anti-slip design, making the cables prone to displacement under vibration or tilting conditions. The unfolding angle of traditional supports requires manual measurement and calibration, and the reliability of locking depends on the manual operation of mechanical clips, which poses safety hazards such as incomplete locking or excessive folding. Utility Model Content

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a foldable cable trench bracket, which can effectively solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A foldable cable trench bracket includes a base, a main support arm, a secondary support arm, and a folding locking assembly for locking the main support arm and the secondary support arm in their unfolded states. One end of the main support arm is rotatably connected to the base via a first hinge shaft, and the other end is rotatably connected to the secondary support arm via a second hinge shaft. Both the main support arm and the secondary support arm are hollow structures.

[0006] The folding locking assembly is disposed between the main support arm and the secondary support arm. The folding locking assembly includes a fixed seat with a groove, a sliding block and a locking pin. The fixed seat is fixed to the outer side wall of the secondary support arm. The sliding block is slidably disposed on the groove of the fixed seat. The locking pin passes through the sliding block and engages with the locking hole on the secondary support arm.

[0007] As a further description of the above technical solution, a reset spring is provided between the sliding block and the fixed base, and an unlock button is provided on the outside of the sliding block.

[0008] As a further description of the above technical solution, both the main support arm and the secondary support arm are provided with reinforcing ribs, which are distributed in a cross shape.

[0009] As a further description of the above technical solution, the base is provided with mounting holes for fixing to the cable trench, and the upper surfaces of the main support arm and the auxiliary support arm are both provided with cable trays.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a foldable cable trench bracket, including a base 1, a main support arm 2, a secondary support arm 3, and a folding locking assembly 4 for locking the main support arm 2 and the secondary support arm 3 in their unfolded state. One end of the main support arm 2 is rotatably connected to the base 1 via a first hinge shaft 101, and the other end is rotatably connected to the secondary support arm 3 via a second hinge shaft 102. Both the main support arm 2 and the secondary support arm 3 are hollow structures.

[0024] In this embodiment, the main support arm 2 is rotatably connected to the base 1 via the first hinge shaft 101, and the secondary support arm 3 is rotatably connected to the main support arm 2 via the second hinge shaft 102, forming a two-stage hinge structure. When the bracket needs to be unfolded, the secondary support arm 3 is manually pushed to rotate around the second hinge shaft 102, causing the main support arm 2 to rotate synchronously around the first hinge shaft 101 until the main support arm 2 and the secondary support arm 3 are unfolded to a preset angle (monitored by the angle sensor 301). At this time, the locking pin 405 in the folding locking assembly 4 automatically inserts into the locking hole 404 of the secondary support arm 3 under the action of the return spring, completing the locking of the unfolded state; when folding, pressing the unlock button pushes the sliding block 402 to slide in the slide groove 403 of the fixed seat 401 against the spring force, causing the locking pin 405 to exit the locking hole 404, and the main and secondary support arms 3 can be folded in reverse.

[0025] The folding locking assembly 4 is disposed between the main support arm 2 and the secondary support arm 3. The folding locking assembly 4 includes a fixed base 401 with a sliding groove 403, a sliding block 402, and a locking pin 405. The fixed base 401 is fixed to the outer side wall of the secondary support arm 3. The sliding block 402 is slidably disposed on the sliding groove 403 of the fixed base 401. The locking pin 405 passes through the sliding block 402 and cooperates with the locking hole 404 on the secondary support arm 3.

[0026] Angle sensor 301 monitors the hinge angle between the main support arm 2 and the auxiliary support arm 3 in real time. When the preset unfolding angle (such as 90°) is reached, the sensor sends an electrical signal to the folding locking assembly 4 (such as an electromagnetic drive mechanism or mechanical linkage device), triggering the locking pin 405 to quickly insert into the locking hole 404, thereby achieving automatic locking and avoiding manual calibration errors.

[0027] Furthermore, a return spring is provided between the sliding block 402 and the fixed base 401, and an unlocking button is provided on the outer side of the sliding block 402. Both the main support arm 2 and the auxiliary support arm 3 are provided with reinforcing ribs 5, which are distributed in a cross shape.

[0028] The cross-shaped reinforcing ribs 5 inside the main and auxiliary support arms 3 divide the hollow cavity into four support areas. Under vertical load, the reinforcing ribs 5 distribute the weight of the cable evenly to the base 1 through the stress dispersion path, reducing the deformation of the arm body and improving the overall rigidity.

[0029] Furthermore, the base 1 is provided with mounting holes for fixing to the cable trench, and the upper surfaces of both the main support arm 2 and the auxiliary support arm 3 are provided with cable trays 6. The cable trays 6 on the upper surfaces of the main and auxiliary support arms 3 provide a cable bearing platform, and the elastic anti-slip pads 601 with wavy texture inside increase friction to prevent cable slippage; the limiting plates 602 on both sides are connected to the adjusting knob through threaded posts 603, and rotating the knob can move the limiting plates 602 axially along the threaded posts 603 to adapt to cables of different diameters, forming an adjustable limiting space.

[0030] Furthermore, the base 1 is provided with a horizontal adjustment mechanism at its bottom. The horizontal adjustment mechanism includes an adjustment screw 103 and a support base 104. One end of the adjustment screw 103 is threadedly connected to the base 1, and the other end is rotatably connected to the support base 104.

[0031] The adjusting screw 103 at the bottom of the base 1 is rotatably connected to the support base 104. When the bracket is placed on uneven ground, rotating the adjusting screw 103 can change the height of the support base 104. The levelness of the bracket is calibrated by the three-point leveling principle (the base 1 and the two support bases 104 form a stable triangular structure) to ensure the stability of the cable load.

[0032] Furthermore, an angle sensor 301 is provided at the hinge joint between the main support arm 2 and the auxiliary support arm 3. The angle sensor 301 is electrically connected to the folding locking assembly 4. When the main support arm 2 and the auxiliary support arm 3 are unfolded to a preset angle, the folding locking assembly 4 automatically triggers the locking mechanism.

[0033] The foldable structure (the main and auxiliary support arms 3 fold to fit the base 1) reduces the volume of the bracket to 1 / 3 to 1 / 2 of its unfolded state, reducing transportation costs. During installation, the bracket is automatically locked by the angle sensor 301, eliminating the need for manual angle measurement. The installation time per station is reduced by more than 60% compared to traditional fixed brackets, making it particularly suitable for rapid construction in narrow cable trenches.

[0034] Furthermore, the cable tray 6 is provided with an elastic anti-slip pad 601 with a wavy texture inside, and adjustable limiting plates 602 are provided on both sides of the cable tray 6. The limiting plates 602 are connected to the cable tray 6 through threaded posts 603, and an adjustment knob is provided at one end of the threaded posts 603.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
