Description

Technical Field

[0001] The present application relates to the technical field of cable brackets, and in particular to an installation bracket for outdoor cable trenches. Background Art

[0002] Cable trench supports are mainly used to support and fix power cables, communication cables and other cables in underground cable trenches. Cable trench supports usually consist of supports, brackets, fasteners and cable clamps. The support directly contacts the ground or the wall of the cable trench and provides basic support. The bracket extends from the support and is used to directly support the cable. It can be designed in different shapes and lengths according to needs. Fasteners include screws, nuts, etc., which are used to fix the support in the cable trench or connect various components. Cable clamps are used to further fix the cables.

[0003] In order to maintain the stability of the cable on the cable trench support, some cable trench supports will also set cable troughs and fixed structures matching the cable troughs on the brackets to limit the cables. However, the size of the cable troughs on the common brackets is fixed, and the spacing between adjacent cable troughs is fixed. When laying cables of different sizes and quantities, the spacing and number of cable troughs cannot be adjusted according to the number and size of the cables. Summary of the invention

[0004] In order to improve the applicability of the support arm, the present application provides a mounting bracket for an outdoor cable trench.

[0005] The present application provides an outdoor cable trench mounting bracket, which adopts the following technical solution, including: The support body comprises a mounting base column and a bracket arm connected to one side of the mounting base column, wherein the bracket arm is perpendicular to the mounting base column; The wire-containing structure comprises a plurality of telescopic rods arranged on the support arm along the length direction of the support arm, the telescopic rods comprising an inner rod, a slide cylinder and a force applying member, the slide cylinder is sleeved and slidably connected to the outside of the inner rod, and the force applying member is used to drive the slide cylinder to slide in a direction away from the support arm; A limit abutment device is movably arranged above the cable accommodating structure and is used for abutting against the cable.

[0006] By adopting the above technical solution, when laying cables, the cables are placed above the cable-holding structure, and the multiple telescopic rods in contact with the cables support the cables and shrink under the gravity of the cables. Through the shrinkage of the multiple telescopic rods, a cable trough that matches the cables is formed on the cable-holding structure. Then, a limit abutment is used to abut against the cables to limit the position of the cables to achieve stable installation of the cables. A cable trough is formed by the cable-holding structure under the action of the gravity of the cables. The size of the cable trough formed is controlled by the size of the cables, and the spacing between adjacent cable troughs is controlled by the placement of adjacent cables and can be adjusted at will. The number of cable troughs is controlled according to the number of cables installed. The size and spacing of the cable troughs can be flexibly adjusted within a certain range according to the cable laying conditions, thereby improving the versatility and practicality of the cable trench bracket.

[0007] Optionally, one end of the slide cylinder away from the support arm is rotatably connected to a ball.

[0008] By adopting the above technical solution, the ball bearings can roll on the surface of the cable, reducing the friction between the slide and the cable, making the cable smoother during placement and position adjustment, avoiding cable damage caused by friction, and increasing the service life of the cable.

[0009] Optionally, the position limiting abutment device includes a load-bearing bracket, a first locking member, and a plurality of locking abutment rods slidably connected to the load-bearing bracket; The bearing bracket is located at one side of the wire-containing structure, and the bearing bracket includes a bearing bar and a guide rod fixed to one side of the bearing bar, the bearing bar is parallel to the bracket arm, and one end of the bearing bar is fixed to the mounting base column, and a plurality of guide rods are arranged at intervals along the length direction of the bearing bar; The locking push rod is arranged in a one-to-one correspondence with the guide rod. The locking push rod is sleeved outside the guide rod and is slidably connected to the guide rod. The first locking piece is used to lock the locking push rod.

[0010] By adopting the above technical solution, the design of the bearing bracket and the guide rod ensures the sliding connection of the locking rod on the bearing bracket, and the sliding connection of the locking rod and the locking function of the first locking member enable the operator to adjust the position of the locking rod according to actual needs, thereby better limiting the cable and improving the installation stability of the cable on the support arm.

[0011] Optionally, the locking abutment rod includes an abutment tube portion and a first roller rotatably connected to one end of the abutment tube portion, and a rotation axis of the first roller is parallel to the supporting bar.

[0012] By adopting the above technical solution, the setting of the first roller reduces the friction between the locking rod and the cable, which is beneficial to the adjustment of the cable after the cable is limited, and improves the safety of cable installation. The design of the roller's rotation axis parallel to the bearing bar ensures that the roller always maintains a stable rolling state during the movement of the cable, avoiding the jamming phenomenon caused by tilting.

[0013] Optionally, the first locking member includes a locking bolt, which is threadedly connected to the locking push rod and is used to tighten the guide rod.

[0014] By adopting the above technical solution, after the locking rod is slid until it abuts against the cable, the locking bolt is rotated to tighten the guide rod, which can effectively lock the locking rod and prevent the locking rod from moving again after sliding to the appropriate position, thereby ensuring the stability and safety of the cable.

[0015] Optionally, the position limiting pressing device comprises an abutment bar and a second locking member, and the abutment bar is parallel to the support arm; One end of the abutment bar is slidably connected to the mounting base column, the abutment bar is used to abut the slide cylinder and the cable at the same time, and the second locking member is used to lock the abutment bar.

[0016] By adopting the above technical solution, one end of the abutment bar is slidably connected to the mounting base column, ensuring its adjustability in the lateral direction, thereby better fitting the layout of the cable. At the same time, the abutment bar can abut the slide tube and the cable at the same time, improving the stability of the cable. The second locking member is used to lock the abutment bar to ensure that it is fixed in a suitable position to prevent loosening due to external factors, thereby ensuring reliable fixation of the cable.

[0017] Optionally, a strip-shaped slide groove is provided on the mounting base column, one end of the abutment bar is slidably provided in the strip-shaped slide groove, and a return spring is connected between the abutment bar and the inner bottom wall of the strip-shaped slide groove; The second locking member comprises a locking screw, one end of which is located in the strip-shaped slide groove; the other end of which passes through the strip-shaped slide groove and is threadedly connected to the mounting base column.

[0018] By adopting the above technical solution, the strip chute set on the installation base column and the abutment strip slidably set in the strip chute, the abutment strip moves along the strip chute to achieve locking and unlocking of the cable. The reset spring connected between the abutment strip and the inner bottom wall of the strip chute makes the abutment strip away from the cable-accommodating structure in the initial state, which is convenient for operators to lay cables at the cable-accommodating structure. When the cable is laid, the locking screw is rotated so that one end of the locking screw abuts against the abutment strip, and the abutment strip is pushed to move in the direction close to the cable-accommodating structure. Until the abutment plate abuts against all cables, at this time, the abutment plate also abuts against the slide cylinder, so that the slide cylinder that does not support the cable slides to the same height, so that all cables on the cable-accommodating structure can be limited, and the abutment strip is locked under the joint action of the reset spring and the locking screw.

[0019] Optionally, one end of the locking screw located in the strip-shaped slide groove is connected to a pressing circular plate, and the diameter of the pressing circular plate is greater than the diameter of the locking screw.

[0020] By adopting the above technical solution, the pressing circular plate at one end of the locking screw contacts the abutment strip, causing the abutment strip to slide in the strip-shaped slide groove, thereby adjusting and locking the position of the abutment strip; the pressing area is increased, and the locking stability is improved.

[0021] Optionally, a second roller is rotatably connected to a side of the abutment bar close to the wire-containing structure, and a rotation axis of the second roller is parallel to the abutment bar.

[0022] By adopting the above technical solution, the second roller reduces the friction between the abutment strip and the cable, improves the installation efficiency and safety of the cable, facilitates the movement and adjustment of the locked cable, avoids cable damage caused by friction, and ensures the stability and service life of the cable.

[0023] Optionally, an anti-corrosion layer is provided outside the support body.

[0024] By adopting the above technical solution, an anti-corrosion layer is provided outside the bracket body, which can effectively prevent the bracket from being corroded by environmental factors, extend the service life of the bracket, and ensure that the bracket can still maintain good mechanical properties and appearance quality during long-term use.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. The present application arranges a plurality of telescopic rods on the supporting arm, each of which includes an inner rod, a slide tube and a force-applying member. The slide tube can slide in the inner rod and extend under the action of the force-applying member, so that the slide tube automatically contracts under the action of the cable's own weight to form a cable trough matching the size of the cable, thereby solving the problem that the fixed-size cable trough of the traditional cable trough bracket cannot adapt to cables of different sizes, and improving the applicability of the supporting arm; 2. In the present application, a ball bearing is rotatably connected to one end of the slide cylinder, and the ball bearing can roll on the surface of the cable, thereby reducing the friction between the slide cylinder and the cable, making the cable smoother during placement and position adjustment, avoiding cable damage caused by friction, and increasing the service life of the cable; 3. In the present application, the limit abutment is movably arranged above the cable-containing structure, and by abutting against the cable, the fixing effect of the cable is further enhanced, the movement of the cable on the bracket is prevented, and the overall stability and safety are improved.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0028] Embodiment 1: Reference Figure 1The outdoor cable trench installation bracket provided in the embodiment of the present application includes a bracket body 1, a wire-holding structure 2 and a limit abutment 3. The bracket body 1 includes a mounting base column 11, a support arm 12 welded and fixed to one side of the mounting base column 11, and a reinforcing connecting rod 13, wherein the support arm 12 is perpendicular to the mounting base column 11; the reinforcing connecting rod 13 is inclined relative to the support arm 12, and one end of the reinforcing connecting rod 13 is welded and fixed to the support arm 12, and the other end is welded and fixed to the mounting base column 11. The bracket body 1 can be made of metal materials, such as steel, aluminum or other high-strength alloy materials, to ensure its sufficient strength and durability. An anti-corrosion layer is provided on the outside of the bracket body 1. The anti-corrosion layer can be made of epoxy resin, polyurethane coating or other materials with excellent anti-corrosion properties. The anti-corrosion layer is coated on the outer surface of the bracket body 1 by spraying to prevent the bracket body 1 from being corroded and extend its service life. The thickness of the anti-corrosion layer ranges from 0.1 mm to 0.5 mm.

[0029] Reference Figure 1 and Figure 2 The cable-holding structure 2 includes a plurality of telescopic rods 21 arranged along the length direction of the supporting arm 12, and each telescopic rod 21 includes an inner rod 211, a slide 212 and a force member 213. One end of the inner rod 211 is fixed on the supporting arm 12, and the slide 212 is sleeved and slidably connected to the outside of the inner rod 211. The force member 213 is specifically configured as a force spring, and a fixing plate 2111 is provided at one end of the inner rod 211 located in the slide 212; one end of the force spring is connected to the fixing plate 2111, and the other end is fixed in the slide 212. The slide 212 is in an extended state when not acted upon by an external force by the elastic force of the force spring. When the cable 6 is placed on the cable-holding structure 2, the slide 212 that provides support for the cable 6 will shrink inward under the gravity of the cable 6, thereby forming a cable trough that matches the size of the cable 6. In other embodiments, the force member 213 can also be configured as a rubber strip.

[0030] Reference Figure 2 , a ball 22 is rotatably arranged at one end of the slide 212 away from the support arm 12, a partition plate 2121 is fixed at one end of the slide 212 away from the support arm 12, and a mounting cavity is formed between the partition plate 2121 and the inner wall of the microphone; the ball 22 is located in the mounting cavity, and one end of the ball 22 passes through the mounting cavity, so as to realize the rotation connection of the ball 22 on the slide 212. One end of the force spring away from the fixed plate 2111 is fixed on the partition plate 2121. When the telescopic rod 21 provides support for the cable 6, the ball 22 directly contacts the cable 6. The friction between the slide 212 and the cable 6 can be significantly reduced, making the cable 6 easier to slide and adjust. The surface of the ball 22 is smooth, which can effectively avoid the wear of the surface of the cable 6 and extend the service life of the cable 6. In other embodiments, the ball 22 may not be arranged.

[0031] Reference Figure 3The position limiting abutment 3 includes a bearing bracket 31, a first locking member, and a plurality of locking abutment rods 33 slidably connected to the bearing bracket 31. The bearing bracket 31 includes a bearing bar 311 and a guide rod 312 welded and fixed to the bearing bar 311, and the guide rod 312 is located on the side of the bearing bar 311 close to the line-containing structure 2; the bearing bar 311 is parallel to the support arm 12, and one end of the bearing bar 311 is fixed to the mounting base column 11; the guide rod 312 is perpendicular to the bearing bar 311, and a plurality of guide rods 312 are arranged at intervals along the length direction of the bearing bar 311. The locking abutment rod 33 includes a cylinder portion 331 and a first roller 332, and the locking abutment rod 33 is arranged one by one with the guide rod 312, and the cylinder portion 331 in the locking abutment rod 33 is sleeved outside the corresponding guide rod 312 and is slidably connected to the guide rod 312. A first rotating support 333 is fixed to one end of the abutting tube portion 331 . The first rotating support 333 includes a first rotating shaft. The first roller 332 is coaxially fixed to the first rotating shaft, and the rotating axis of the first roller 332 is parallel to the supporting bar 311 .

[0032] In other embodiments, the first roller 332 and the first rotating support 333 may not be provided.

[0033] Reference Figure 3 The first locking member includes a locking bolt 32, which is threadedly connected to an end of the abutment barrel 331 away from the first roller 332, and is used to abut the guide rod 312. The first roller 332 is movably arranged above the cable accommodating structure 2, and the sliding locking abutment 33 can make the first roller 332 abut against the cable 6 laid on the cable accommodating structure 2, thereby preventing the cable 6 from moving on the support arm 12. Then, the locking bolt 32 is rotated to abut the rotating locking bolt 32 against the guide rod 312, thereby fixing the position of the locking abutment 33. The design of the limit abutment 3 makes the position of the cable 6 on the support arm 12 more stable, prevents the cable 6 from sliding under the action of external force, and ensures the stable installation of the cable 6.

[0034] The implementation principle of this embodiment is: by arranging a plurality of telescopic rods 21 on the bracket arm 12, the sliding characteristics of the telescopic rods 21 can be used to automatically form a cable groove that matches the size of the cable 6. This design can adapt to cables 6 of different sizes and quantities, and improves the applicability of the bracket arm 12. At the same time, the design of the limit abutment 3 can effectively prevent the cable 6 from sliding on the bracket arm 12, ensuring the stable installation of the cable 6. This structure not only simplifies the installation process of the cable 6, but also improves the fixing effect of the cable 6, reducing the construction difficulty and maintenance cost.

[0035] Embodiment 2: Reference Figure 4 and Figure 5The difference between this embodiment and the above-mentioned embodiment is that the bearing bracket 31, the first locking member and the locking abutment rod 33 are not provided in this embodiment. The position limiting abutment device 3 includes an abutment strip 34 and a second locking member. The abutment strip 34 is parallel to the support arm 12. One end of the abutment strip 34 is slidably connected to the mounting base column 11. The abutment strip 34 is used to abut the slide cylinder 212 and the cable 6 at the same time. The second locking member is used to lock the abutment strip 34. A strip-shaped slide groove 111 is provided on the mounting base column 11. One end of the abutment strip 34 slides in the strip-shaped slide groove 111 to achieve a sliding connection on the mounting base column 11. A reset spring 4 is connected between the abutment strip 34 and the inner bottom wall of the strip-shaped slide groove 111. The reset spring 4 can provide a constant resilience so that the abutment strip 34 remains in the initial position when not subjected to external force.

[0036] Reference Figure 2 The second locking member includes a locking screw 35, one end of which is located in the strip slide groove 111, and the other end of which is connected to the hand wheel 5 after passing through the strip slide groove 111, and the locking screw 35 is threadedly connected to the mounting base column 11. A pressing circular plate 351 is fixed to one end of the locking screw 35 located in the strip slide groove 111, and the diameter of the pressing circular plate 351 is larger than the diameter of the locking screw 35, which can increase the locking area and improve the locking effect.

[0037] Reference Figure 2 A second roller 36 is provided on the side of the abutment bar 34 close to the line-containing structure 2. A second rotating support 37 is fixed on one side of the abutment bar 34, and the second rotating support 37 includes a second rotating shaft; the second roller 36 is coaxially fixed on the second rotating shaft, and the rotation axis of the second roller 36 is parallel to the abutment bar 34. By providing the second roller 36 on the abutment bar 34, the friction between the abutment bar 34 and the slide 212 can be significantly reduced, making it easier for the abutment bar 34 to be adjusted slightly after being locked. The surface of the second roller 36 is smooth, which can effectively avoid wear of the slide 212 and the cable 6, and extend their service life.

[0038] Reference Figure 1 and Figure 2 After laying the cable 6 at the cable-accommodating structure 2, the hand wheel 5 is rotated to drive the pressing circular plate 351 to push the abutment bar 34, so that the abutment bar 34 slides toward the direction close to the cable-accommodating structure 2; until the second roller 36 abuts against all the cables 6. At this time, the second roller 36 also abuts against the ball 22 in the cable-accommodating structure 2, so that the slide cylinder 212 that does not support the cable 6 slides to the same height, and all the cables 6 on the cable-accommodating structure 2 can be limited. The design of the limit abutment 3 makes the position of the cable 6 on the bracket 12 more stable, prevents the cable 6 from sliding under the action of external force, and ensures the stable installation of the cable 6.

[0039] In other embodiments, the second roller and the second rotating support may not be provided.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
