Description

Technical Field

[0001] This utility model relates to the field of street code application technology, and in particular to a street code that is easy to replace. Background Technology

[0002] Street code is a support and fixing device for overhead conductors installed in outdoor public areas such as streets and alleys in low-voltage power distribution networks. Its core function is to fix and support low-voltage overhead lines and ensure the safe and orderly laying of the lines.

[0003] When using cable trays to support and fix overhead conductors, the conductors are usually placed on rollers for fixation, and then fixed to the building wall using mounting brackets and supports. However, the existing bolt or welding connection method between the cable tray rollers and the supports is subject to wind and rain erosion and friction during long-term outdoor use, which leads to aging, damage or jamming of the roller surface. Since the disassembly and assembly process requires special tools, this not only increases the complexity and time cost of maintenance, but may also cause inconvenience in operation, affecting the normal use of the equipment and timely replacement. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using street code to support and fix overhead conductors, the overhead conductors are usually placed on rollers for fixation, and then fixed to the building wall by mounting brackets and supports. However, the existing bolt or welding connection method between the rollers and supports of street code is subject to wind and rain erosion and friction during long-term outdoor use, resulting in aging, damage or jamming of the roller surface. Since the disassembly and assembly process requires special tools, this not only increases the complexity and time cost of maintenance, but may also lead to inconvenience in operation, affecting the normal use of the equipment and timely replacement.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a street code that is easy to replace, including a mounting frame and several rollers. Several brackets are symmetrically fixed on one side of the mounting frame. A disassembly mechanism is provided between the brackets and the rollers. When the rollers need to be disassembled and replaced, the disassembly mechanism only requires manually pressing the locking block to slide it in the slide groove to a certain position, causing the spring to contract and pulling one end of it out of the second locking groove. This releases the limiting fixation between the mounting block and the bracket. Then, by pulling the roller to one end, the mounting block can be pulled out of the first locking groove on the bracket, and the roller can be removed from the bracket. No additional tools are required for disassembly, which is convenient for operation.

[0006] Preferably, the easy-to-disassemble mechanism includes two mounting blocks, a first slot is provided on one side of the bracket, and a second slot is provided on both sides of the inner wall of the first slot, wherein the mounting block is inserted into the inner wall of the first slot, and a sliding groove is provided on both sides of the mounting block; a plurality of locking blocks, wherein the locking blocks are slidably installed in the inner wall of the sliding groove, and one end is inserted into the inner wall of the second slot; and a plurality of springs, wherein the two ends of the springs are respectively fixedly installed on one side of the locking block and one side of the inner wall of the sliding groove.

[0007] The aforementioned components achieve the following effect: By setting up a convenient disassembly mechanism, when using street brackets to support and fix overhead conductors, the overhead conductors are usually placed on rollers for fixation. Then, they are detachably fixed to the building wall using mounting brackets and supports with bolts. When the rollers show signs of aging and damage after prolonged use and need replacement, the overhead conductors installed on the rollers are first pulled loose. Then, the locking block can be manually pressed into one end of the inner wall of the slide groove to a certain position, causing the spring to contract and pulling one end out of the second locking slot. Then, the roller is pulled to one end, causing the mounting block to be pulled out of the first locking slot, thus removing the roller from the support for easy replacement and maintenance. This operation can be performed without additional tools, simplifying the operation steps, reducing the complexity and time cost of maintenance, and avoiding affecting the normal use of the equipment and timely replacement.

[0008] Preferably, one end of the mounting block has a trapezoidal cross-section.

[0009] The effect achieved by the above components is that by setting one end of the mounting block into a trapezoidal shape, the area of ​​one end can be reduced, making it easier to quickly align with the first slot and insert it, thus facilitating rapid installation.

[0010] Preferably, the easy-to-disassemble mechanism further includes several telescopic sleeves, wherein the inner wall of the telescopic sleeve is sleeved on the outer surface of the spring, and both ends are respectively fixedly installed on one side of the locking block and one side of the inner wall of the slide groove.

[0011] The effect achieved by the above components is that by setting a telescopic sleeve, the outer surface of the spring can be covered, making it difficult for external dust and impurities to get stuck in the spring gaps and affect its use. At the same time, it reduces the contact between the spring and the outside world, avoiding corrosion and damage.

[0012] Preferably, the outer surface of the roller is provided with a plurality of limiting mechanisms, the limiting mechanism including an elastic arc block, wherein one side of the elastic arc block is fixedly installed on the outer surface of the roller, and the outer surface of the overhead wire is inserted into the inner wall of the elastic arc block.

[0013] The effect achieved by the above components is as follows: by setting a limiting mechanism, when the overhead conductor is placed on the roller for support and fixation, the outer surface of the overhead conductor can be inserted into the inner wall of the elastic arc block, so that the elastic arc block undergoes corresponding deformation to fix the overhead conductor on the roller, which facilitates wiring construction and improves the usability of the roller code.

[0014] Preferably, limit blocks are fixedly installed at both ends of the elastic arc block, and the limit blocks are fixed at an angle on both sides of the entrance of the elastic arc block.

[0015] The effect achieved by the above components is that by setting the limiting block, the area at the entrance of the elastic arc block can be increased, making it easier for the overhead wire to be quickly aligned and inserted, thus facilitating installation.

[0016] Preferably, a plurality of anti-slip blocks are fixedly installed on the inner wall of the elastic arc block, and the plurality of anti-slip blocks are made of rubber.

[0017] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction of the inner wall of the elastic arc block can be increased, making the overhead wire more firmly and stably limited after being stuck in the inner wall of the elastic arc block.

[0018] The beneficial effects of this utility model are: By incorporating a convenient disassembly mechanism, when using street brackets to support and fix overhead conductors, the conductors are typically placed on rollers for fixation. They are then detachably fixed to the building wall using bolts via mounting brackets and supports. When the rollers show signs of aging and damage after prolonged use and require replacement, the overhead conductors mounted on the rollers are first loosened. Then, the locking block can be manually pressed into one end of the slide groove to a certain position, causing the spring to contract and pull one end out of the second locking slot. The roller is then pulled to one end, causing the mounting block to be pulled out of the first locking slot, thus removing the roller from the bracket for easy replacement and maintenance. This operation requires no additional tools, simplifies the process, reduces maintenance complexity and time costs, and avoids affecting the normal use of the equipment and timely replacement.

[0028] Figure 1-5 The street code shown includes a mounting frame 1 and several rollers 5. Several brackets 4 are symmetrically fixed on one side of the mounting frame 1. A disassembly mechanism 2 is provided between the brackets 4 and the rollers 5. When it is necessary to disassemble and replace the rollers 5, the disassembly mechanism 2 only requires manually pressing the locking block 26 to slide it in the slide groove 24 to a certain position, causing the spring 25 to contract and pull one end of it out of the second locking groove 22. This releases the limiting fixation between the mounting block 23 and the bracket 4. Then, by pulling the roller 5 to one end, the mounting block 23 can be pulled out of the first locking groove 21 on the bracket 4, and the roller 5 can be removed from the bracket 4. It can be removed without additional tools, which is convenient for operation.

[0029] Figure 1-5The disassembly mechanism 2 shown includes two mounting blocks 23. A first slot 21 is provided on one side of the bracket 4. A second slot 22 is provided on both sides of the inner wall of the first slot 21. The mounting block 23 is inserted into the inner wall of the first slot 21. A sliding groove 24 is provided on both sides of the mounting block 23. Several locking blocks 26 are provided, wherein the locking blocks 26 are slidably installed in the inner wall of the sliding groove 24, and one end is inserted into the inner wall of the second slot 22. Several springs 25 are provided, wherein the two ends of the springs 25 are respectively fixedly installed on one side of the locking block 26 and one side of the inner wall of the sliding groove 24. By setting up the easy-to-remove mechanism 2, when using the street code to support and fix the overhead conductor, the overhead conductor is usually placed on the roller 5 for fixation. Then, it is detachably fixed to the building wall by bolts through the mounting bracket 1 and the support 4. When the roller 5 needs to be replaced due to aging and damage after long-term use, the overhead conductor installed on the roller 5 is first pulled loose. Then, the locking block 26 can be manually pressed into one end of the inner wall of the slide groove 24 to a certain position, causing the spring 25 to contract and pull one end out of the second locking groove 22. Then, the roller 5 is pulled to one end, causing the mounting block 23 to be pulled out of the first locking groove 21. Thus, the roller 5 can be removed from the support 4 for easy replacement and maintenance. This operation can be removed without additional tools, the operation steps are simple, the complexity and time cost of maintenance are reduced, and it avoids affecting the normal use of the equipment and timely replacement.

[0030] Figure 1-5 The mounting block 23 shown has a trapezoidal cross-section at one end. By making one end of the mounting block 23 trapezoidal, the area at one end can be reduced, making it easier to quickly align with the first slot 21 and insert it, thus facilitating rapid installation. The easy-to-disassemble mechanism 2 also includes several telescopic sleeves 27, the inner wall of which is fitted onto the outer surface of the spring 25, and both ends are fixedly installed on one side of the locking block 26 and one side of the inner wall of the slide groove 24, respectively. By setting the telescopic sleeves 27, the outer surface of the spring 25 can be covered, making it difficult for external dust and impurities to get stuck in the gaps of the spring 25 and affect its use, while reducing the contact between the spring 25 and the outside world, thus avoiding corrosion and damage.

[0031] Figure 1-5 The outer surface of the roller 5 shown is provided with several limiting mechanisms 3. Each limiting mechanism 3 includes an elastic arc block 31, one side of which is fixedly installed on the outer surface of the roller 5. The outer surface of the overhead wire is inserted into the inner wall of the elastic arc block 31. By setting the limiting mechanism 3, when the overhead wire is placed on the roller 5 for support and fixation, the outer surface of the overhead wire can be inserted into the inner wall of the elastic arc block 31, causing the elastic arc block 31 to deform accordingly and fix the overhead wire on the roller 5. This facilitates wiring construction and improves the usability and adaptability of the roller 5.

[0032] Figure 1-5Both ends of the elastic arc block 31 shown are fixedly equipped with limiting blocks 32, which are inclinedly fixed on both sides of the entrance of the elastic arc block 31. By setting the limiting blocks 32, the area at the entrance of the elastic arc block 31 can be increased, making it easier for the overhead wire to be quickly aligned and inserted, thus facilitating installation. Several anti-slip blocks 33, made of rubber, are fixedly installed on the inner wall of the elastic arc block 31. By setting the anti-slip blocks 33, the contact friction of the inner wall of the elastic arc block 31 can be increased, making the overhead wire more firmly and stably limited after being inserted into the inner wall of the elastic arc block 31.

[0033] Working principle: When using the street code to support and fix overhead conductors, the overhead conductors are usually placed on rollers 5 for fixation. Then, they are detachably fixed to the building wall by bolts through the mounting bracket 1 and the support 4. When the rollers 5 show signs of aging and damage after long-term use and need to be replaced, first loosen the overhead conductors installed on the rollers 5. Then, manually press the locking block 26 into one end of the inner wall of the slide groove 24 to a certain position, causing the spring 25 to contract and pull one end out of the second locking groove 22. Then pull the rollers 5 to one end, causing the mounting block 23 to be pulled out of the first locking groove 21. Thus, the rollers 5 can be removed from the support 4 for easy replacement and maintenance. This operation can be performed without additional tools, which is simple and reduces the complexity and time cost of maintenance, avoiding affecting the normal use of the equipment and timely replacement.

[0034] When the overhead conductor is placed on the roller 5 for support and fixation, the outer surface of the overhead conductor can be inserted into the inner wall of the elastic arc block 31, so that the elastic arc block 31 deforms accordingly to fix the overhead conductor on the roller 5, which facilitates wiring construction and improves the usability of the roller 5.
