Description

Technical Field

[0001] This invention relates to the field of communication manhole technology, specifically a 360-degree universal adapter for communication manholes. Background Technology

[0002] To improve the installation efficiency of communication manholes, the main body of the manhole is cast in the factory using a large injection molding machine and then transported to the site for direct excavation and burial. During use, pipes are installed around the main body of the manhole according to the distribution of cables. However, in the existing technology, the pipes and the main body of the manhole are generally rigidly connected, which makes it easy to break the pipes when pulling cables later. Because of the rigid connection and the relatively dense distribution of pipes, it is difficult to install the pipes and it is also inconvenient to fix cable markings on the outer surface of the pipes. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a 360-degree universal adapter for communication manholes, which has advantages such as preventing pipes from being broken by the pulling force of cables, facilitating pipe installation, and making it easy to install markings on the outer surface of pipes. It solves the problems of pipes being easily broken by the pulling force of cables, and the inconvenience of pipe installation and marking on the outer surface of pipes.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned objectives of preventing pipes from being broken by cable traction, facilitating pipe installation, and enabling the installation of markings on the outer surface of the pipes, this invention provides the following technical solution: a 360-degree universal adapter for communication manholes, comprising a communication manhole body, with connector connection holes around the periphery of the communication manhole body, a silicone sealing sleeve being snapped into the connector connection hole, an arc-shaped rotating sleeve being inserted into the silicone sealing sleeve, a connecting cylinder being threaded to the outer end of the arc-shaped rotating sleeve, an outer connecting pipe being inserted into one end of the connecting cylinder, and silicone sealing rings being provided between the outer connecting pipe and the connecting cylinder, and between the connecting cylinder and the arc-shaped rotating sleeve.

[0007] Preferably, the outer diameter of the silicone sealing sleeve is larger than the inner diameter of the connector connection hole, and the outer surface of the silicone sealing sleeve is provided with an annular groove that engages with the connector connection hole, the diameter of the annular groove being slightly larger than the inner diameter of the connector connection hole.

[0008] Preferably, the material of the arc-shaped rotating sleeve is a rubber tube with high hardness but can be bent. The arc-shaped rotating sleeve is fitted with the silicone sealing sleeve, and the inner end of the arc-shaped rotating sleeve is provided with a step that prevents the silicone sealing sleeve from passing through.

[0009] Preferably, the connecting sleeve is made of rigid plastic, and the outer diameter of the connecting sleeve is the same as that of the arc-shaped rotating sleeve, but the outer diameter of one end is reduced and is provided with an external thread that connects with the threaded connection of the arc-shaped rotating sleeve.

[0010] Preferably, the outer tube is made of plastic, and the outer tube is fitted with the connecting cylinder with a clearance fit. The outer tube cannot be inserted into the silicone sealing sleeve.

[0011] Preferably, the silicone sealing ring is installed in the annular groove on the inner wall of the connecting cylinder and in the annular groove on the outer side. The silicone sealing ring seals the fitting gap between the outer pipe and the connecting cylinder, as well as the fitting gap between the connecting cylinder and the arc-shaped rotating sleeve.

[0012] Preferably, the outer surface of the internally threaded portion of the arc-shaped rotating sleeve and the outer surface of the middle portion of the connecting cylinder are provided with anti-slip printing.

[0013] Preferably, the outer end of the connecting cylinder has a relatively thin wall thickness and an opening groove, which allows the outer end of the connecting cylinder to change its diameter.

[0014] Preferably, a certain distance is set between the connection holes of each joint, and a certain distance is also set between each arc-shaped rotating sleeve, so that the arc-shaped rotating sleeve has room to bend.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a 360-degree universal adapter for communication manholes, which has the following beneficial effects:

[0017] 1. This 360-degree universal adapter for communication manholes, through the setting of an arc-shaped rotating sleeve, enables the adapter to prevent the pipe from being broken by the traction force of the cable. By connecting the pipe through the arc-shaped rotating sleeve that can rotate 360 ​​degrees, the pipe automatically changes direction to be parallel to the traction force when subjected to the traction force of the cable, thereby achieving the effect of preventing the pipe from being broken by the traction force of the cable.

[0018] 2. This 360-degree universal adapter for communication manholes, through the coordinated design of an arc-shaped rotating sleeve, a connecting cylinder, and an external pipe, facilitates both pipe installation and label installation on the pipe's outer surface. The arc-shaped rotating sleeve, capable of 360-degree rotation, allows the pipe to change direction under stress, enabling the manhole to move adjacent pipes to create space even when pipes are closely spaced. The external pipe connects to the connecting cylinder via a plug-in connection, making it easy to install and remove. When label installation is needed on the pipe's outer surface, obstructing pipes can be moved aside to create operating space, or the pipe can be pulled out of the connecting cylinder for label installation.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-4A 360-degree universal adapter for a communication manhole includes a communication manhole body 1. A connector connection hole 101 is formed around the periphery of the communication manhole body 1. A silicone sealing sleeve 2 is snapped into the connector connection hole 101. The outer diameter of the silicone sealing sleeve 2 is larger than the inner diameter of the connector connection hole 101. An annular groove is formed on the outer side of the silicone sealing sleeve 2 to engage with the connector connection hole 101. The diameter of the annular groove is slightly larger than the inner diameter of the connector connection hole 101, allowing the silicone sealing sleeve 2 to be securely snapped into the connector connection hole 101. A [missing information - likely a device or component] is inserted into the silicone sealing sleeve 2. The arc-shaped rotating sleeve 3 is made of a high-hardness but flexible rubber tube. It transitions into the silicone sealing sleeve 2. When the arc-shaped rotating sleeve 3 is inserted into the silicone sealing sleeve 2, the silicone sealing sleeve 2 is stretched and deformed, thus sealing the gap between the arc-shaped rotating sleeve 3 and the connector connection hole 101. The inner end of the arc-shaped rotating sleeve 3 has a step that prevents the silicone sealing sleeve 2 from passing through. A certain distance is maintained between each connector connection hole 101, and similarly, a certain distance is maintained between each arc-shaped rotating sleeve 3. The arc-shaped rotating sleeve 3 has a bending space. A connecting cylinder 4 is threadedly connected to the outer end of the arc-shaped rotating sleeve 3. The connecting cylinder 4 is made of rigid plastic. The outer diameter of the connecting cylinder 4 is the same as that of the arc-shaped rotating sleeve 3, but one end has a reduced outer diameter and is provided with an external thread for threaded connection with the arc-shaped rotating sleeve 3. The outer surface of the arc-shaped rotating sleeve 3 with its internal thread and the outer surface of the middle part of the connecting cylinder 4 are provided with anti-slip printing. An outer connecting pipe 5 is inserted into one end of the connecting cylinder 4. The outer end of the connecting cylinder 4 has a relatively thin wall and an opening groove, through which the outer end of the connecting cylinder 4 is connected. The diameter can be changed to facilitate the insertion of the outer tube 5 into the connecting tube 4. The outer tube 5 is made of plastic and is fitted with the connecting tube 4 with a clearance. The outer tube 5 cannot be inserted into the silicone sealing sleeve 2. Silicone sealing rings 6 are provided between the outer tube 5 and the connecting tube 4, and between the connecting tube 4 and the arc-shaped rotating sleeve 3. The silicone sealing rings 6 are installed in the annular grooves opened on the inner wall and outer side of the connecting tube 4. The silicone sealing rings 6 seal the fit clearance between the outer tube 5 and the connecting tube 4, and between the connecting tube 4 and the arc-shaped rotating sleeve 3.

[0026] In use, first, install the silicone sealing sleeve 2 into the connector connection hole 101. Then, insert the arc-shaped rotating sleeve 3 into the silicone sealing sleeve 2 from the inside out. At this time, the silicone sealing sleeve 2 is deformed by the arc-shaped rotating sleeve 3, sealing the installation gap between the arc-shaped rotating sleeve 3 and the connector connection hole 101. Next, install the silicone sealing ring 6 into the annular groove opened inside the connecting cylinder 4. Then, insert the outer pipe 5 into the connecting cylinder 4. Next, install the silicone sealing ring 6 into the annular groove opened outside the connecting cylinder 4. Then, connect the connecting cylinder 4 to the arc-shaped rotating sleeve 3 through threads. During the connection process between the connecting cylinder 4 and the arc-shaped rotating sleeve 3, the arc-shaped rotating sleeve 3 is relatively densely distributed. Workers can use their hands to move the already installed connecting cylinder 4 to the side to make room for their hands. After installing all the outer pipes 5, the main body 1 of the communication manhole is buried in the ground. The next step is to connect the cables inside and outside the main body 1 of the communication manhole through the universal adapter. During the cable installation process, since the arc-shaped rotating sleeve 3 can rotate freely, the outer pipe 5 can automatically change direction according to the traction force of the cable, thus avoiding the outer pipe 5 from being broken due to lateral force. After the cable is installed, if it is necessary to install a mark on the corresponding outer pipe 5, if there is not enough space, the surrounding outer pipes 5 that are in the way can be moved aside, or the outer pipe 5 can be pulled out from the connecting cylinder 4 and slid along the cable to a position that is easy to operate to install the mark.

[0027] In summary, this 360-degree universal adapter for communication manholes connects to the pipe via a 360-degree rotatable arc-shaped rotating sleeve 3. This allows the pipe to automatically change direction and parallel to the traction force when subjected to cable tension, thus preventing the pipe from being broken by the cable tension. The 360-degree rotatable arc-shaped rotating sleeve 3 allows the pipe to change direction under force, enabling the installation of other pipes even when pipes are closely spaced. Since the outer pipe 5 is connected to the connecting cylinder 4 via a plug-in connection, the outer pipe 5 is easy to install and remove. When it is necessary to install a label on the outer surface of the pipe, obstructing pipes can be cleared to create operating space, or the pipe can be pulled out of the connecting cylinder 4 to facilitate label installation on the outer surface of the pipe.
