Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge with a concealed installation function. Background Art

[0002] A cable tray system is a structure used for routing cables. Its design and material selection are crucial to ensuring the durability and functionality of the system. Cable trays are mainly divided into the following types: trough, tray, ladder, and grid. Each type has its own specific application scenarios and advantages. The bottom of the tray-type cable tray is open, which can provide good ventilation and heat dissipation. This design also facilitates cable installation and maintenance and is often used in places with high heat dissipation requirements, such as large data centers and industrial plants.

[0003] When installing cable trays, it's often necessary to navigate around pipes, obstructions, and corners. Traditional installation methods rely on measuring angles and lengths, then cutting and splicing the cable tray. This approach is not only complex but also easily impacts installation efficiency. Measurement errors can lead to inaccurate cable tray splicing, gaps, and a less-than-ideal final result. Furthermore, this approach lacks the flexibility to adjust precisely around obstacles and corners, increasing installation difficulty and time. Therefore, cable trays with concealed installation capabilities have been proposed to address these issues. Utility Model Content

There is a protective shell on the outside of the two fixing blocks to enhance stability and safety. The overall design ensures high-precision fixation and adjustment of objects, and improves the convenience and safety of operation.

[0008] As a further description of the above technical solution:

[0009] The fixing assembly includes two fixing plates, the bottoms of the two fixing plates are respectively fixedly connected to the tops of the two bridge frames, the tops of the fixing plates are fixedly connected to four support blocks, the inner sides of the plurality of support blocks are slidably connected to sliding rods, the adjacent ends of the plurality of sliding rods are fixedly connected to a clamping plate, the outer sides of the ends of the plurality of sliding rods adjacent to the clamping plate are sleeved with springs, and the ends of the plurality of sliding rods away from the clamping plate are fixedly connected to a limiting ring;

[0010] Furthermore, the bottoms of the two fixed plates are securely mounted on the tops of the two bridges, providing a sturdy foundation. Each fixed plate is topped with four support blocks, each with a sliding rod positioned inside. A clamping plate is fixed to one end of the sliding rod, and a spring is installed on the outside of the clamping plate to provide the necessary rebound force. A limiting ring is installed on the end of the sliding rod away from the clamping plate to control the range of movement of the sliding rod. This design ensures the stability and flexibility of the clamping plate when clamping objects, while also allowing for more precise and reliable adjustment of the clamping position.

[0011] As a further description of the above technical solution:

[0012] Two nuts are slidably connected to both sides of the two fixing blocks, and a plurality of screw holes are provided on both sides of the two fixing blocks;

[0013] Furthermore, these nuts can move along a set track on either side of the fixing block. These screw holes are designed to mate with the nuts, allowing them to be fixed in different positions, providing flexible adjustment options. This design allows the fixing block to be precisely positioned as needed, improving the adaptability and functionality of the entire device.

[0014] As a further description of the above technical solution:

[0015] The upper and lower ends of the tooth column are engaged with the two tooth rings, and the interiors of the two tooth rings are rotatably connected to the outer sides of the rotating column;

[0016] Furthermore, the upper and lower ends of the tooth column engage with two tooth rings. The interiors of these tooth rings are rotatably connected to the exterior of the rotating column, allowing the tooth rings to rotate freely outside the rotating column. This structural design ensures smooth and precise movement, and improves the flexibility and efficiency of system operation.

[0017] As a further description of the above technical solution:

[0018] The outer side of the handle is fixedly connected to the top of the two rotating blocks, and the outer sides of the multiple nuts are slidably connected to the inside of the multiple screw holes;

[0020] As a further description of the above technical solution:

[0021] Both sides of the bottom of the limiting rod are fixedly connected to the outer side of the rotating block;

[0022] Furthermore, the outer side of the rotating block may have a fixed interface, such as a hole, notch, or bracket, that mates with the bottom of the limit rod. This ensures that the limit rod is securely mounted and effectively transmits operating force. The stability of the limit rod is crucial to the performance of the entire mechanical system. Through this fixed method, it provides the necessary guidance and limiting functions on the outer side of the rotating block, thereby achieving precise control and operation.

[0023] As a further description of the above technical solution:

The design of fixing the spring on the splint and the support block helps to maintain the stable position of the splint and avoid instability caused by operational fluctuations.

[0029] The utility model has the following beneficial effects:

[0030] 1. In the utility model, the staff pulls the handle to drive the rotating blocks on both sides to release the tooth ring from the restriction. At this time, one of the fixed blocks can be rotated to drive the tooth column to rotate. The angle adjustment can avoid the need for secondary processing during the installation of the cable tray if the length of the cable tray does not match the actual requirements.

[0031] 2. In the utility model, the staff drives the sliding rod to slide backward by pushing the two clamping plates to both sides. When the cable is placed in the specified position and the restriction on the clamping plates is released, the spring will provide power to clamp and fix the cable, thereby fixing the cable to prevent it from being displaced from its original position by external impact. These devices can firmly fix the cable on the bridge to prevent it from moving due to external force. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1 、 Figure 2 、 Figure 4 The utility model provides an embodiment: a cable tray with a concealed installation function, comprising two cable trays 1, which are the main supporting structures for carrying other components and are usually made of strong materials to ensure stability and durability. The adjacent sides of the two cable trays 1 are fixedly connected with fixing components for fixing objects, and these components are used to ensure that the objects are firmly positioned on the cable trays 1. The outer sides of the two cable trays 1 are slidably connected with fixing blocks 8, which allow the positions of the objects to be adjusted and fixed. Two nuts 9 are slidably connected to both sides of the two fixing blocks 8, which can be adjusted and fixed in different positions to enhance the stability of the fixing blocks 8. A plurality of screw holes 19 are provided on both sides of the two fixing blocks 8.

[0040] Bolt connectors are allowed to pass through for further fixation and adjustment. The outer top of the fixed block 8 is fixedly connected to a tooth column 12, which is used to cooperate with other gear components to provide power transmission or adjustment functions. The upper and lower ends of the tooth column 12 are engaged with two tooth rings 13. This tooth cooperation can achieve precise angle adjustment and locking functions. The interiors of the two tooth rings 13 are rotatably connected to the outside of the rotating column 14. This enables the tooth rings 13 to rotate around the rotating column 14, thereby achieving the required movement and adjustment. The outer top of another fixed block 8 is fixedly connected to two tooth rings 13 for precise adjustment and fixation.

[0041] The tooth column 12 is internally rotatably connected to a rotating column 14, allowing the rotating column 14 to rotate within the tooth column 12, enabling flexible motion adjustment. The top of the rotating column 14 is fixedly connected to a fixed column 15 for further component fixation and support. Rotating blocks 16 are rotatably connected to both sides of the fixed column 15, which can rotate around the fixed column 15 to provide additional motion adjustment capabilities. The outer sides of the two rotating blocks 16 are rotatably connected to tooth rings 13, which work together with other gear accessories to enhance the adjustment and fixing capabilities of the system. The bottom of the rotating column 14 is fixedly connected to a limiting disk 11 for limiting the rotation range or providing additional fixing functions.

[0042] Another tooth ring 13 is fixedly connected to the top of the limiting disk 11 for cooperating with other gear components. A handle 17 is fixedly connected to the top of the fixed column 15. The fixed column 15 is a vertically supported columnar component with a handle 17 on its top. The handle 17 is designed to facilitate the operator to grasp and move the fixed column 15. This handle 17 may be fixed to the top of the fixed column 15 by welding. The internal rotation of the fixed column 15 is connected to a limiting rod 18. Inside the fixed column 15, there is a rotatable component called the limiting rod 18. The limiting rod 18 is connected to the fixed column 15 through a bearing or other rotation connection mechanism, so that it can rotate around an axis inside the fixed column 15.

[0043] The bottom sides of the limiting rod 18 are fixedly connected to the outside of the rotating block 16. The bottom sides of the limiting rod 18 are welded to the outside of the two rotating blocks 16 by some other connection method. The outside of the rotating blocks 16 is designed to accommodate this connection method to ensure that the limiting rod 18 maintains stable contact with the rotating blocks 16 during rotation. The outside of the handle 17 is fixedly connected to the top of the two rotating blocks 16. The outside of the handle 17 is also fixedly connected to the top of the two rotating blocks 16.

[0044] This connection is achieved via a latch, restricting the movement of rod 18 within rotating block 16. Nuts 9 are slidably connected on their outer sides to screw holes 19. This design allows nuts 9 to slide in one direction within screw holes 19, facilitating position adjustment and fastener installation. Housing 10 is rotatably connected to the outer sides of both fixed blocks 8. This connection allows housing 10 to rotate relative to fixed blocks 8, providing flexible movement.

[0045] Reference Figure 3 The fixing assembly includes two fixing plates 2. This structural design ensures a stable connection between the fixing plates 2 and the bridge frame 1, thereby supporting the fixation and operation of the entire assembly. The bottoms of the two fixing plates 2 are fixedly connected to the tops of the two bridge frames 1 respectively. These support blocks 3 are fixed to the tops of the fixing plates 2 by bolts, welding or other means to support other components or parts. Four support blocks 3 are fixedly connected to the tops of the fixing plates 2, which means that the sliding rod 4 can slide freely in one direction on the inner side of the support block 3, thereby realizing the adjustment or positioning function.

[0046] The inner sides of the multiple support blocks 3 are slidably connected to sliding rods 4. Nearby ends of the multiple sliding rods 4 are fixedly connected to clamping plates 7. These clamping plates 7 are arc-shaped, allowing them to more accurately conform to the shape of the object being clamped during operation, thereby providing a better clamping effect. The rotating block 16 is elliptical in shape. This shape allows the rotating block 16 to provide support or connection in different directions during movement, making the entire assembly more flexible.

[0047] A spring 6 is sleeved on the outside of one end of the multiple sliding rods 4 close to the splint 7. The function of the spring 6 is to provide a restoring force or an adjusting force to keep the splint 7 and the sliding rod 4 in a good connection state. One end of the spring 6 is fixedly connected to the outside of the splint 7. This connection method enables the spring 6 to provide the necessary elastic support to help the splint 7 move and position on the sliding rod 4. The other end of the spring 6 is fixedly connected to the inner side of the support block 3. A limiting ring 5 is fixedly connected to one end of the multiple sliding rods 4 away from the splint 7. The function of the limiting ring 5 is to limit the range of motion of the sliding rod 4 to ensure that the sliding rod 4 does not exceed the predetermined range during operation.

[0048] Working principle: The staff puts the cable on the top of the bridge 1, and then spreads the two clamps 7 to both sides. Because the support block 3 used to fix the sliding rod 4 is hollow, when the staff spreads the clamps 7 in different directions, the sliding rod 4 will slide outward. When the staff puts the cable in the specified position, the restriction on the clamps 7 can be released, and the clamps 7 will be brought back to their original position by the spring 6 to fix and restrict the cable. When the staff encounters a corner, they can manually control the handle 17 to drive the rotation of the rotating block 16. Because the design of the rotating block 16 is elliptical, it has one more protrusion on both sides than the normal circle. In the supported and restricted state, the position of the protrusion is against the top of the toothed ring 13. When the rotating block 16 rotates, the position of the protrusion will leave the top of the toothed ring 13. At the same time, because the top of the limiting disk 11 is fixedly connected to the bottom of the rotating column 14, under normal circumstances, the limiting disk 11 is spaced apart from the toothed ring 13 below. Only when rotating When the block 16 restricts the upper tooth ring 13, the rotating column 14 will be lifted up because the protrusion of the rotating block 16 hits the upper tooth ring 13, driving the limiting plate 11 to restrict the lower tooth ring 13. At the same time, because one side of the two tooth rings 13 is fixedly connected to the inner side of one of the fixed blocks 8, when fixedly connected, it is set to be an upper and lower oblique angle, the upper tooth ring 13 is inclined upward, and the lower tooth ring 13 is inclined downward. Because the material of the tooth ring 13 itself is tough, when the rotating block 16 is rotated, the tooth ring 13 will lose the lower limiting plate 11 and the upper rotating block 16 and thus tilt up. At this time, the tooth column 12 will be free from the restrictions of the tooth rings 13 on the upper and lower sides. At this time, the staff can rotate the fixed block 8 to drive the tooth column 12 to adjust the angle, avoiding the need to cut the bridge frame 1 too long, reducing time and avoiding the uneven cutting size due to improper operation of the staff, which leads to uneven connection during subsequent connection.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
