Abstract
Description
Technical Field
[0001] This utility model relates to a cable tray, specifically a trough-type cable tray, and belongs to the field of cable tray technology. Background Technology
[0002] A trough-type cable tray is a trough-shaped component made from a single sheet of steel. Conceptually, it differs from a cable tray in its height-to-width ratio; cable trays are shallow and wide, while trough-type cable trays have a certain depth and enclosure, allowing for fully enclosed cable laying. It offers good shielding against interference for control cables and protection for cables in highly corrosive environments.
[0003] Chinese patent application publication number CN222508668U discloses a trough-type cable tray. This utility model facilitates the installation of bolts by setting a connecting mechanism, ensuring the installation efficiency of the cable tray. It also facilitates the opening of the inspection cover by setting an inspection cover and a closing mechanism, allowing workers to easily inspect the cables through the opening by separating the latch and buckle. The operation is relatively simple.
[0004] While the solutions in the aforementioned patents facilitate cable maintenance, the cable trays in these patents do not allow for individual fixing of the internal cables. Most existing methods for fixing cables in cable trays use clamps and cable ties, which can cause the internal cables to become tangled, thus limiting the usable space inside the cable tray.
[0005] Therefore, a trough-type cable tray is proposed here. Utility Model Content
[0006] This utility model proposes a trough-type cable tray that can individually fix cables of different sizes, and can rotate the connecting rod to move the arc-shaped clamp away from the cable, making it convenient for cable maintenance.
[0007] This utility model is achieved through the following technical solution: a trough-type cable tray, including a mounting box, a lower mounting seat fixed inside the mounting box, an upper mounting seat above the mounting box, a snap-fit assembly connected to the mounting box on one side of the upper mounting seat, the snap-fit assembly including a support block fixed to one side of the upper mounting seat, two positioning shafts fixed to one side of the support block, a locking rod hinged to the periphery of the positioning shaft, and a positioning hook at the bottom end of the locking rod engaging with a triangular block.
[0008] Furthermore, a spring is fixed between the two levers, and the spring is located at the top of the two levers.
[0009] Furthermore, a hinge is installed between the mounting box and the upper mounting base, and a triangular block is fixed to the side of the mounting box away from the hinge.
[0010] The upper mounting base has a set of limiting grooves inside, and a set of arc-shaped clamps is provided on the bottom surface of the upper mounting base. The upper mounting base has a set of positioning components for fixing the position of the arc-shaped clamps inside. The positioning components include a connecting rod sleeved inside the upper mounting base. A connecting sleeve is slidably sleeved on the bottom of the connecting rod and fixed to the surface of the arc-shaped clamps. A first compression spring is installed between the bottom surface of the connecting rod and the arc-shaped clamps. A set of locking blocks is fixed on the outer periphery of the limiting groove of the connecting rod, and the inner diameter of the limiting groove is larger than the outer diameter of the connecting sleeve.
[0011] Furthermore, a limiting ring is fixedly sleeved on the bottom surface of the connecting rod, and the limiting ring is slidably sleeved on the inner side wall of the connecting sleeve.
[0012] Furthermore, the upper mounting base has a set of storage slots inside, and a positioning block is slidably sleeved inside the storage slots. A second compression spring is fixed between the positioning block and the inner sidewall of the storage slot.
[0013] Furthermore, isolation pads are fixed on the sides of the lower mounting base and the arc-shaped clamp that are close to each other, and the position of the arc-shaped clamp corresponds to the groove on the surface of the lower mounting base.
[0014] This utility model provides a trough-type cable tray, which has the following beneficial effects:
[0015] 1. This trough-type cable tray, when the connecting rod is pressed, triggers two positioning blocks by a locking block, fixing the cable between the lower mounting base and the arc-shaped clamp. When the arc-shaped clamp contacts the surface of the cable, it causes the positioning component to slide around the connecting rod. The first compression spring pushes the arc-shaped clamp to facilitate the individual fixing of cables of different sizes. Rotating the connecting rod causes the locking block to rotate and move away from the positioning block. Then, the connecting rod is lifted upward and rotated to reset it, allowing the arc-shaped clamp to move away from the cable, facilitating cable maintenance.
[0016] 2. This trough-type cable tray places the cable inside the groove on the surface of the lower mounting base, and then closes the upper mounting base, allowing the bottom ends of the two clamps to slide on the surface of the triangular block. The springs then move the top ends of the two clamps away from each other, so that the bottom ends of the two clamps can contact the bottom surface of the triangular block and fix the position of the upper mounting base.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0029] Please see Figures 1-4 The present invention proposes the following implementation scheme: a trough-type cable tray, including a mounting box 1, a lower mounting seat 2 fixed inside the mounting box 1, an upper mounting seat 3 above the mounting box 1, a snap-fit assembly 5 connected to the mounting box 1 on one side of the upper mounting seat 3, the snap-fit assembly 5 including a support block 51 fixed on one side of the upper mounting seat 3, two positioning shafts 52 fixed on one side of the support block 51, a locking rod 53 hinged to the periphery of the positioning shaft 52, and the bottom end of the locking rod 53 being configured as a positioning hook that snaps into a triangular block 11.
[0030] Please refer to this carefully. Figure 3 A spring 54 is fixed between the two levers 53, and the spring 54 is located at the top of the two levers 53.
[0031] In the above scheme, closing the upper mounting base 3 allows the bottom ends of the two locking rods 53 to slide on the surface of the triangular block 11, and the spring 54 is used to move the top ends of the two locking rods 53 away from each other, so that the bottom ends of the two locking rods 53 can contact the bottom surface of the triangular block 11 and fix the position of the upper mounting base 3.
[0032] A hinge 4 is installed between the mounting box 1 and the upper mounting base 3, and a triangular block 11 is fixed on the side of the mounting box 1 away from the hinge 4.
[0033] Please refer to this carefully. Figure 2 and Figure 4 The upper mounting base 3 has a set of limiting grooves 31 inside. The bottom surface of the upper mounting base 3 is provided with a set of arc-shaped clamps 6. The upper mounting base 3 has a set of positioning components 8 inside to fix the position of the arc-shaped clamps 6. The positioning components 8 include a connecting rod 81 sleeved inside the upper mounting base 3. The bottom of the connecting rod 81 is slidably sleeved with a connecting sleeve 82, and the connecting sleeve 82 is fixed to the surface of the arc-shaped clamps 6. A first compression spring 83 is installed between the bottom surface of the connecting rod 81 and the arc-shaped clamps 6. A set of locking blocks 84 are fixed around the connecting rod 81 at the periphery of the limiting groove 31, and the inner diameter of the limiting groove 31 is larger than the outer diameter of the connecting sleeve 82.
[0034] Please refer to this carefully. Figure 4 The bottom surface of the connecting rod 81 is fixedly fitted with a limiting ring 87, and the limiting ring 87 is slidably fitted on the inner side wall of the connecting sleeve 82.
[0035] In the above scheme, when the arc-shaped clamp 6 contacts the surface of the cable, the arc-shaped clamp 6 causes the positioning component 8 to slide around the connecting rod 81 and compress the first compression spring 83. The first compression spring 83 pushes the arc-shaped clamp 6 so as to fix cables of different sizes individually.
[0036] The upper mounting base 3 has a set of storage slots 32 inside, and a positioning block 85 is slidably sleeved inside the storage slot 32. A second compression spring 86 is fixed between the positioning block 85 and the inner side wall of the storage slot 32.
[0037] In the above scheme, pressing the connecting rod 81 causes the locking block 84 to trigger the two positioning blocks 85 to move away from the connecting rod 81. Then, the second compression spring 86 pushes the positioning blocks 85 to slide on the top surface of the locking block 84, so that the connecting rod 81 and the connecting sleeve 82 drive the arc-shaped clamp 6 to contact the surface of the cable, fixing the cable between the lower mounting base 2 and the arc-shaped clamp 6. Rotating the connecting rod 81 causes the locking block 84 to rotate and move away from the positioning block 85. Then, the connecting rod 81 is lifted upward and rotated to reset it, which can make the arc-shaped clamp 6 move away from the cable.
[0038] Please refer to this carefully. Figure 2The lower mounting base 2 and the arc-shaped clamp 6 are both fixed with isolation pads 7 on their sides that are close to each other, and the position of the arc-shaped clamp 6 corresponds to the groove on the surface of the lower mounting base 2.
[0039] In use, the mounting box 1 is installed in the desired position. The cable is then placed inside the groove on the surface of the lower mounting base 2. The upper mounting base 3 is then closed, allowing the bottom ends of the two locking rods 53 to slide on the surface of the triangular block 11. A spring 54 is used to move the top ends of the two locking rods 53 away from each other, ensuring the bottom ends of the two locking rods 53 contact the bottom surface of the triangular block 11 and fixing the position of the upper mounting base 3. Then, the connecting rod 81 is pressed, causing the locking block 84 to trigger the two positioning blocks 85 to move away from the connecting rod 81. A second compression spring 86 then pushes the positioning blocks 85 to slide on the top surface of the locking block 84, causing the connecting rod 81 to slide away from the top surface of the locking block 81. 1. The connecting sleeve 82 drives the arc-shaped clamp 6 to contact the surface of the cable, fixing the cable between the lower mounting base 2 and the arc-shaped clamp 6. When the arc-shaped clamp 6 contacts the surface of the cable, the arc-shaped clamp 6 drives the positioning component 8 to slide around the connecting rod 81 and compress the first compression spring 83. The first compression spring 83 pushes the arc-shaped clamp 6 to facilitate the individual fixing of cables of different sizes. Rotating the connecting rod 81 causes the locking block 84 to rotate and move away from the positioning block 85. Then, the connecting rod 81 is lifted upward and rotated to reset it, which allows the arc-shaped clamp 6 to move away from the cable, facilitating the maintenance of the cable.
