Description

Technical Field

[0001] This utility model belongs to the field of embedded parts technology, specifically relating to an embedded channel with a locking structure. Background Technology

[0002] Pre-embedded channels, also known as channel-type embedded parts, are connectors that are fixed in concrete through pre-embedding. Compared with traditional concrete embedding and anchoring technology, pre-embedded channels can avoid structural damage to the tunnel segments caused by drilling, and can also improve installation quality and the working environment for electromechanical installation.

[0003] The existing technology has the following problems:

[0004] 1. Currently, most of the pre-embedded channels on the market have a fixed length and do not have a locking mechanism, which makes it inconvenient to adjust the length of the pre-embedded channel according to the working environment during the use of the device.

[0005] 2. Currently available pre-embedded channels deform under the loads transmitted by contact wires, escape platforms, pipelines, etc. after installation, thus affecting their functionality and increasing the workload of later maintenance during operation, and they do not have anti-corrosion effects. Utility Model Content

[0006] The purpose of this invention is to provide a pre-embedded channel with a locking structure for existing devices, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pre-embedded channel with a locking structure, including a first pre-embedded channel, a second pre-embedded channel movably connected to one side of the first pre-embedded channel, a fixing block fixedly connected to one side of the inner side of the first pre-embedded channel, and a locking block fixedly connected to one side of the fixing block.

[0008] A mounting block is fixedly connected to one side of the second pre-embedded channel. A pin is provided inside the mounting block. A first clamping block is rotatably connected to the outer wall of the pin. A second clamping block is provided on one side of the first clamping block.

[0009] The present invention further illustrates that springs are fixedly connected to both sides of the top of the mounting block, and the top of the springs is fixedly connected to the bottom of one side of the first clamping block and the second clamping block.

[0010] Using the above technical solution, the first clamping block and the second clamping block are reset by the characteristics of the spring, thereby clamping the locking block.

[0011] The present invention further explains that the outer walls of the first and second pre-embedded channels are both fixedly connected with anti-corrosion layers, and the bottom side of the first and second pre-embedded channels is fixedly connected with a fixing plate. The top of the fixing plate is fixedly installed with reinforcing ribs, and there are multiple reinforcing ribs arranged at the same horizontal level.

[0012] The above technical solution uses a nano-multi-alloy co-permeation anti-corrosion coating as the anti-corrosion layer material. Therefore, the pre-embedded channel is not easily corroded by concrete. The multiple reinforcing ribs provide the pre-embedded channel with anti-deformation ability, strong stability, and effectively improve the anti-deformation ability, ensuring the functionality and reducing the amount of maintenance work in the later stage of operation.

[0013] The present invention further illustrates that the top of the fixing plate is provided with an installation hole, and the top of the first pre-embedded channel and the second pre-embedded channel are fixedly installed with pre-embedded anchor rods.

[0014] Using the above technical solution, the pre-embedded channel is installed and fixed through the mounting holes opened on the top of the fixing plate.

[0015] The present invention further explains that fixing holes are provided on both sides of the first pre-embedded channel, and a bolt is threadedly connected to one side of the first pre-embedded channel. The bolt passes through the interior of the first pre-embedded channel and the fixing hole for threaded connection.

[0016] In the above technical solution, the fixing block and the mounting block are fixed inside the first and second pre-embedded channels by bolts.

[0017] The present invention further explains that a limiting hole is provided on one side of both the first clamping block and the second clamping block, and an anti-loosening rod is provided inside one side of the first pre-embedded channel. The anti-loosening rod passes through the first pre-embedded channel and is inserted into the limiting hole.

[0018] In the above technical solution, after the first and second pre-embedded channels of the locking mechanism are connected, the first clamping block and the second clamping block are fixed by inserting the anti-loosening rod into the limiting hole.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0020] This utility model provides a pre-embedded channel with a locking structure. A fixing block and an installation block are fixed inside the first and second pre-embedded channels using bolts. A locking block is placed in the middle of the first and second clamping blocks, and pushed to compress the locking block towards the center of the first and second clamping blocks. A spring generates pressure, causing the first and second clamping blocks to rotate on the outer surface of the pin to reset. The locking block is then fixed inside the first and second clamping blocks. An anti-loosening rod is inserted into the limiting hole to fix the first and second clamping blocks, thus limiting their vertical movement and preventing them from sliding up and down. Therefore, the first and second clamping blocks are effectively secured and prevented from loosening. The length of the pre-embedded channel can be adjusted according to the working environment, meeting the user's needs.

[0021] This utility model provides a pre-embedded channel with a locking structure. Through the anti-corrosion layer applied to the outer surfaces of the first and second pre-embedded channels, and using a nano-multi-alloy co-permeable anti-corrosion coating, the pre-embedded channel is less susceptible to concrete corrosion. Multiple reinforcing ribs provide resistance to deformation, resulting in strong stability and improved stability. This enhances the stability of the pre-embedded channel, ensures its functionality, reduces maintenance workload during operation, and meets the user's needs. Attached Figure Description

The spring 9 generates pressure, and the first clamping block 7 and the second clamping block 8 rotate on the outer surface of the pin 6 to reset. The locking block 4 is fixed inside the first clamping block 7 and the second clamping block 8. Then, the first clamping block 7 and the second clamping block 8 are fixed by inserting the anti-loosening rod 18 into the limiting hole 17, so that the upper and lower limits can be set, thereby making the first The clamping block 7 and the second clamping block 8 cannot slide up or down.
