Description

Technical Field

[0001] The utility model relates to the technical field of bridge bends, in particular to an aluminum alloy bridge bend. Background Art

[0002] Aluminum alloy bridge bend is a key component in the aluminum alloy bridge system. Aluminum alloy bridge is a support and protection structure for laying cables and wires, and is widely used in electrical wiring projects. Aluminum alloy bridge bend is a bridge part with a specific bending angle. Common bending angles are 90°, 45°, etc. It is mainly used to change the laying direction of the cable so that the wiring can adapt to the building structure and electrical layout requirements. From a structural point of view, it is made of aluminum alloy, which has the characteristics of light weight, corrosion resistance, and beauty. The internal space is used to accommodate cables, and its design must ensure that the cable can transition smoothly at the bend to avoid damage to the cable sheath. At the same time, it must ensure sufficient mechanical strength to withstand the weight of the cable and adapt to possible external force impacts.

[0003] Existing aluminum alloy bridge bends usually lay cables inside the bridge bend. Since the internal space of the bridge bend is relatively large to ensure heat dissipation, the cables are prone to shaking and shifting inside the aluminum alloy bridge, which makes the cable stability poor. In addition, existing aluminum alloy bridge bends usually do not have a cable fixing structure, which causes the cables to be damaged during long-term use, resulting in a reduced service life of the cables. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, the cables are prone to shaking and shifting inside the aluminum alloy bridge during use, and the cables are prone to wear after long-term use, which reduces the service life of the cables.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4As shown, the utility model provides an aluminum alloy bridge bend, including a bridge body 1, the top of the inner wall of the bridge body 1 is fixedly connected to multiple groups of lower arc-shaped splints 2, the outer walls of the multiple groups of lower arc-shaped splints 2 are fixedly connected to a first rubber pad 3, the top of the bridge body 1 is provided with four embedding grooves 4, the inner surface walls of the four embedding grooves 4 are movably inserted with embedding blocks 5, the tops of the four embedding blocks 5 are fixedly connected with a cover plate 6, the top of the cover plate 6 is provided with a threaded groove 7, the inner surface wall of the threaded groove 7 is threadedly connected to an adjusting screw 8, and the outer surface wall of the adjusting screw 8 is fixedly sleeved with a bearing 9. A sliding groove 10 is provided on one side of the outer wall of the four embedded blocks 5. Sliders 11 are slidably embedded in the inner walls of the four sliding grooves 10. A lifting plate 12 is fixedly connected between one side of the outer wall of the four slides 11, and the outer wall of the bearing 9 is movably inserted into the inside of the lifting plate 12. A group of first springs 13 are fixedly connected to the bottom of the lifting plate 12, and a mounting plate 14 is fixedly connected between the bottoms of a group of first springs 13. A plurality of groups of upper arc-shaped splints 15 are fixedly connected to the bottom of the mounting plate 14. The outer walls of the plurality of groups of upper arc-shaped splints 15 are fixedly connected to a second rubber pad 16.

[0024] The effect achieved by the entire embodiment 1 is that after the cables are properly placed between the multiple groups of lower arc-shaped clamping plates 2, the axial movement of the adjusting screw 8 is achieved by precisely controlling the rotation of the adjusting screw 8 and utilizing its close cooperation with the thread groove 7. As the adjusting screw 8 rotates and presses downward, one end of the adjusting screw drives the lifting plate 12 to descend steadily, thereby linking a group of first springs 13 and the mounting plate 14 to move downward synchronously. This series of actions causes the multiple groups of upper arc-shaped clamping plates 15 to fit closely to the cable surface, achieving a stable and uniform clamping effect. In this process, a group of first springs 13 not only provides the necessary clamping holding force, and also gives the clamping mechanism a certain elastic buffer, making the clamping process softer, effectively avoiding hard damage to the cable. At the same time, the provision of multiple groups of first rubber pads 3 and multiple groups of second rubber pads 16 further improves the softness and friction of the clamping surface, ensures the stability and safety of the cable during the clamping process, and effectively prevents the sliding and wear of the cable, so that multiple cables can maintain a stable posture when in use, reducing the potential risks caused by shaking or displacement, thereby ensuring the stable operation of the electrical system and significantly extending the service life of the cable.

[0025] Example 2, as Figure 2-Figure 4 As shown, a slot 17 is provided on one side of the outer wall of the four embedded blocks 5, and a block 18 is movably inserted into the inner wall of the four slots 17. A second spring 19 is fixedly connected to one side of the outer wall of the four blocks 18, and a limiting block 20 is fixedly connected to one side of the outer wall of the four blocks 18. Four fixed blocks 21 are fixedly installed on the outer wall of the bridge body 1, and a blocking rod 22 is movably inserted into the inner wall of the four fixed blocks 21.

[0026] The effect achieved by the entire embodiment 2 is that, first of all, the tight installation of the cover plate 6 effectively prevents external dust, moisture and corrosive substances from invading the interior of the bridge body 1, thereby ensuring the cleanliness and dryness of the internal environment of the bridge, and extending the service life of the cable and the bridge. When it is necessary to install the cover plate 6, first, the four embedded blocks 5 are accurately inserted into the corresponding embedded grooves 4. As the embedded blocks 5 gradually move downward, their outer wall will squeeze the inclined surface of the card block 18, causing the card block 18 to move along one side and compress the second spring 19 at the same time, generating elastic deformation. When the embedded block 5 is completely and firmly inserted into the embedded groove 4, the second spring 19 uses its restoring force to push the card block 18 automatically snaps into the corresponding card slot 17, thereby realizing a firm connection between the cover plate 6 and the bridge frame body 1, ensuring the stability of the installation. When the cover plate 6 needs to be removed, first move the corresponding baffle 22 upwards, and then push the limit blocks 20 one by one to make the block 18 move to one side under the action of pressure until the limit block 20 passes the baffle 22. At this time, push the baffle 22 downwards, and use the blocking effect of the baffle 22 to keep the limit block 20 in a fixed position, thereby releasing the locking state of the embedded block 5. In this way, the cover plate 6 can be easily removed from the bridge frame body 1, which not only facilitates maintenance operations, but also ensures the detachability and flexibility of the bridge frame structure.

[0027] Working principle: When in use, first place the cable accurately between multiple groups of lower arc-shaped clamping plates 2 to ensure the initial positioning of the cable. Then, embed the four embedding blocks 5 into the corresponding embedding grooves 4 one by one. During this process, the inclined outer surface of the embedding block 5 will squeeze the inclined surface of the card block 18, prompting the card block 18 to slide along one side and compress the second spring 19, causing it to produce elastic deformation. As the embedding block 5 completely and smoothly enters the embedding groove 4, the second spring 19 uses its inherent restoring force to push the card block 18 to quickly and accurately snap into the corresponding card groove 17, thereby achieving a stable installation between the cover plate 6 and the bridge body 1, effectively preventing the intrusion of adverse external factors. Subsequently, by fine-tuning the adjusting screw 8, using its precise fit with the threaded groove 7, the adjusting screw 8 is rotated. This action causes one end of the adjusting screw to drive The lifting plate 12 moves downward smoothly in the vertical direction, and the smooth sliding of the four sliders 11 in the corresponding slide grooves 10 further enhances the stability and reliability of the movement of the lifting plate 12. The downward movement of the lifting plate 12 immediately drives a group of first springs 13 and the mounting plate 14 to descend synchronously, thereby prompting multiple groups of upper arc-shaped clamping plates 15 to fit tightly and firmly clamp the cable. A group of first springs 13 not only provides the necessary clamping force, but also gives the clamping mechanism a certain elastic buffer, making the clamping process softer and more adaptable, effectively protecting the cable from hard damage. In addition, the provision of multiple groups of first rubber pads 3 and multiple groups of second rubber pads 16 further enhances the softness and friction of the clamping surface, ensuring the stability and safety of the cable during the clamping process, while reducing wear and indentation on the cable surface.
