Description

Technical Field

[0001] The utility model relates to the technical field of wire tubes, and more specifically to a flame-retardant galvanized wire tube. Background Art

[0002] Wires buried in the wall must be threaded through pipes. Generally, metal threading pipes and PVC threading pipes are available. PVC threading pipes have a certain flame retardant effect. Existing galvanized wire pipes are mostly welded when splicing. Welding requires a power source and welding equipment, resulting in low splicing efficiency and long working time. At the same time, the galvanized wire pipes after welding form a whole with a long length, which is not convenient for later maintenance and replacement of the line.

[0003] In view of the above problems, the existing galvanized wire pipes are connected by welding, which has the technical problems of low efficiency and long time. After a lot of searches, a flame retardant galvanized wire pipe with patent application number 202322151021.0 was found, which belongs to the field of wire pipe technology, including two galvanized wire pipes, and two mounting holes are provided on the outside of the two galvanized wire pipes. A splicing mechanism is provided on the outside of the two galvanized wire pipes; the splicing mechanism includes an upper mounting plate and a lower mounting plate, and the upper mounting plate and the lower mounting plate are respectively sleeved on the outside of the two galvanized wire pipes. The beneficial effect of the galvanized wire tube is that the elastic force of the limit spring in the splicing mechanism causes the connecting rod to move the trapezoidal block 1 downward, and the movement of the trapezoidal block 1 squeezes the trapezoidal block 2, so that the limit plate extends from the cavity and extends into the limit groove. The right-angle surface on the top of the limit plate cooperates with the limit groove so that the lower mounting plate and the upper mounting plate will not be separated from each other, and the splicing operation is completed. The operation is simple, no other equipment is required, and it is easy to release the splicing state, which is convenient for the later maintenance of its internal lines. However, the technical solution provided by the patent has the following problems:

[0004] The galvanized wire pipe is segmented before use, and a splicing mechanism is used to connect the galvanized wire pipes. However, most of the splicing mechanisms use springs for limiting, and then a limiting plate is embedded in the cavity for limiting, so that the two galvanized wire pipes are connected. However, the galvanized wire pipe needs to be moved back and forth during installation, resulting in a large shake. During the continuous shaking, the spring is not stable enough, which can easily cause the connection of the galvanized wire pipe to break, resulting in the galvanized wire pipe being unstable during use. In severe cases, the galvanized wire pipe collapses, posing a certain safety hazard.

[0005] The utility model can make the pipe body more stable when connected, and further improve the safety of the pipe body. Utility Model Content

[0006] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides a flame-retardant galvanized wire pipe.

[0007] To achieve the above object, the utility model provides the following technical solutions: A flame-retardant galvanized wire pipe, comprising: a pipe body, a connection group is nested on the outer surface of the pipe body, two card slots are opened on the outer surface of the pipe body, and a thread is circumferentially opened at one end of the pipe body; The connection group consists of two snap rings and a limiting rod. Positioning blocks are fixedly installed at both ends of the two snap rings, and the positioning blocks are connected by bolts.

[0008] Further preferred solution: Threads are opened on the inner sides of the two snap rings. The two snap rings are spliced and nested on the outer surface of the pipe body, and the two snap rings are movably connected to the pipe body.

[0009] Further preferred solution: The two snap rings are connected to the threaded end of the pipe body, and the two snap rings are movably connected to the pipe body. A flame-retardant layer is sprayed on the outer surface of the pipe body.

[0010] Further preferred solution: The limiting rod penetrates through both ends of the snap ring, and a baffle is fixedly installed on the outer side of the limiting rod. The baffle is located outside the snap ring.

[0011] Further preferred solution: A spring is installed at one end of the limiting rod. The spring can be embedded inside the snap ring, and the spring is slidably connected to the snap ring.

[0012] Further preferred solution: A limiting block is fixedly installed at the other end of the spring. Both the limiting block and the spring can be embedded inside the snap ring, and the limiting block can be embedded inside the card slot.

[0013] Further preferred solution: A support plate is nested on the outer surface of the limiting rod. The middle of the support plate is arc-shaped. The inner side of the support plate is attached to the outer side of the limiting rod, and a pull rope is arranged between the limiting rod and the support plate.

[0014] Beneficial effects:

[0015] 1. By providing snap rings, the snap rings are used to connect two pipe bodies. The snap rings are rotated so that the internal threads are connected to the threads on the outer side of the pipe body, so that the snap rings are located between the two pipe bodies, and then the two pipe bodies are connected. The threaded connection method is more convenient to use. The threads can increase the friction between the snap ring and the pipe body, improve the connection stability. At the same time, the threads can also play a certain sealing role to prevent external dust, moisture and other impurities from entering the pipe body, protecting the internal wires and cables. The two snap rings are spliced and nested on the outer surface of the pipe body, making the installation and disassembly of the snap rings more convenient and fast. When in use, the snap rings can be installed on the pipe body or removed from the pipe body according to needs, which is convenient for the connection and maintenance of the wire pipes. A flame-retardant layer is sprayed on the outer surface of the pipe body. The flame-retardant layer can effectively prevent the spread of fire, improve the fire resistance of the wire pipe, and make the pipe body safer to use;

[0016] 2. By setting a limit rod, after the two pipe bodies are connected, the support block outside the limit rod is removed. Then, the limit rod drives the limit rod to move by the pressure of the spring, so that the spring drives the limit rod to embed into the internal of the card slot for further limitation, making the snap ring more stable on the outside of the pipe body. The baffle can effectively prevent the limit rod from falling off the snap ring, ensuring that the limit rod always stays in the correct position. The existence of the baffle also provides a convenient operation point for the operator. When installing and disassembling the snap ring, the limit rod can be moved by pushing the baffle, making the operation more convenient, and thus making it more convenient and flexible for the staff during installation;

[0017] 3. In summary, for this flame-retardant galvanized wire pipe, by setting structures such as a connection group, the connection group is used to connect the two pipe bodies, and the snap ring is used to connect the two pipe bodies. The snap ring is rotated so that the internal thread is connected to the thread on the outside of the pipe body, so that the snap ring is located between the two pipe bodies. After the two pipe bodies are connected, the support block outside the limit rod is removed. Then, the limit rod drives the limit rod to move by the pressure of the spring, so that the spring drives the limit rod to embed into the internal of the card slot for further limitation, making the snap ring more stable on the outside of the pipe body. The nested connection method is more stable during installation, thereby improving the safety between the pipe bodies. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Figures 1-5 For a clear and complete description of the technical solutions in the embodiments of the present invention.

[0025] Please refer to Figures 1-5, in the embodiment of the present utility model, a flame-retardant galvanized wire pipe includes: a pipe body 1, a connection group 2 is nested on the outer surface of the pipe body 1, two card slots 101 are opened on the outer surface of the pipe body 1, and a thread is circumferentially provided at one end of the pipe body 1; the connection group 2 is composed of two snap rings 201 and a limiting rod 202. Positioning blocks 203 are fixedly installed at both ends of the two snap rings 201, and the positioning blocks 203 are connected by bolts; the pipe body 1 serves as the main part of the galvanized wire pipe, mainly used to protect the internal wires and cables from being damaged by the external environment, such as physical impact, moisture erosion, etc. At the same time, the galvanized material has good corrosion resistance and can extend the service life of the wire pipe. The two card slots 101 opened on the outer surface of the pipe body 1 have specific functions. During the installation process, these card slots 101 may cooperate with other accessories or fixing devices to ensure the stable position of the wire pipe. The thread circumferentially provided at one end of the pipe body 1 facilitates the connection with other wire pipes. Through threaded connection, quick and firm connection can be achieved, ensuring the sealing and stability of the wire pipe system. The two snap rings 201 in the connection group 2 play a role in connecting and fixing adjacent wire pipes. The design of the snap ring 201 can be tightly sleeved on the outer surface of the pipe body 1 and connected through the positioning blocks 203 at both ends. The positioning blocks 203 at both ends of the snap ring 201 provide fixed points for the connection, and the bolt connection facilitates adjustment and maintenance when needed. During the connection process, the limiting rod 202 may play a role in assisting positioning and enhancing the connection stability, thereby making the connection of the wire pipe more convenient. The nested connection method makes the wire pipe more stable after connection, thereby improving the safety of the wire pipe use to a certain extent.

[0026] In the embodiment of the present utility model, threads are provided on the inner sides of both snap rings 201. The two snap rings 201 are spliced and nested on the outer surface of the pipe body 1. The two snap rings 201 are movably connected to the pipe body 1. Among them, the two snap rings 201 are connected to the threaded end of the pipe body 1, and the two snap rings 201 are movably connected to the pipe body 1. A flame-retardant layer is sprayed on the outer surface of the pipe body 1; threads are provided on the inner sides of both snap rings 201. The thread design enables the snap rings 201 to better combine with the pipe body 1. When the two snap rings 201 are spliced and nested on the outer surface of the pipe body 1, the threads can increase the friction between the snap rings 201 and the pipe body 1, improving the connection stability. At the same time, the threads can also play a certain sealing role to prevent external dust, moisture and other impurities from entering the inside of the pipe body 1, protecting the internal wires and cables. The two snap rings 201 are spliced and nested on the outer surface of the pipe body 1, making the installation and disassembly of the snap rings 201 more convenient and fast. In practical applications, the snap rings 201 can be installed on or removed from the pipe body 1 at any time according to needs, facilitating the connection and maintenance of the wire pipes. A flame-retardant layer is sprayed on the outer surface of the pipe body 1. The flame-retardant layer can effectively prevent the spread of fire, improving the fireproof performance of the wire pipe. In case of a fire, the flame-retardant layer can delay the spread of the fire, buying time for personnel evacuation and fire extinguishing, and reducing the losses caused by the fire. In addition to the flame-retardant function, the flame-retardant layer can also play a certain protective role for the pipe body 1. It can prevent the pipe body 1 from being affected by external environmental corrosion, wear and ultraviolet radiation, etc., extending the service life of the pipe body 1. At the same time, the flame-retardant layer can also improve the insulation performance of the pipe body 1, reducing the risk of faults such as short circuits of the wires and cables, and thus improving the safety of the pipe body 1 in use.

[0027] In the embodiment of the present utility model, the limiting rod 202 penetrates through both ends of the clamping ring 201. A baffle 204 is fixedly installed on the outer side of the limiting rod 202. The baffle 204 is located on the outer side of the clamping ring 201. Among them, a spring 205 is installed at one end of the limiting rod 202. The spring 205 can be embedded inside the clamping ring 201, and the spring 205 is in a sliding connection with the clamping ring 201. The limiting rod 202 plays a role in enhancing the connection stability of the clamping ring 201. It can prevent the clamping ring 201 from deforming or being misaligned during the connection process, ensuring that the clamping ring 201 can tightly wrap around the outer surface of the pipe body 1, thereby improving the reliability of the connection. The baffle 204 can effectively prevent the limiting rod 202 from falling off the clamping ring 201, ensuring that the limiting rod 202 always remains in the correct position. The presence of the baffle 204 also provides a convenient operation point for the operator. When installing and disassembling the clamping ring 201, the limiting rod 202 can be moved by pushing the baffle 204, making the operation more convenient. The spring 205 installed at one end of the limiting rod 202 can provide a pre-tightening force for the clamping ring 201. When the clamping ring 201 is installed on the pipe body 1, the spring 205 is compressed, generating a certain elastic force, making the clamping ring 201 fit more tightly on the outer surface of the pipe body 1. This pre-tightening force can improve the connection strength between the clamping ring 201 and the pipe body 1, prevent the clamping ring 201 from loosening, making the two clamping rings 201 more stable when connected, and thus improving the stability of the connection of the pipe body 1 to a certain extent.

[0028] In the embodiment of the present utility model, a limiting block 206 is fixedly installed at the other end of the spring 205. Both the limiting block 206 and the spring 205 can be embedded inside the clamping ring 201, and the limiting block 206 can be embedded inside the card slot 101. When the spring 205 is in a compressed state, the limiting block 206 can tightly press against the inside of the clamping ring 201 under the elastic force of the spring 205, further enhancing the connection stability between the clamping ring 201 and the pipe body 1. It can prevent the clamping ring 201 from loosening or displacing during use, ensuring the firmness of the connection of the wire pipe. The limiting block 206 can be embedded inside the card slot 101. After the limiting block 206 is embedded in the card slot 101, the position of the clamping ring 201 on the pipe body 1 is accurately determined, avoiding the sliding or rotation of the clamping ring 201 on the pipe body 1, helping to improve the accuracy and reliability of the connection of the wire pipe, ensuring the correct positional relationship of each connection part, and thus ensuring the normal operation of the entire wire pipe system. During the installation process, when the clamping ring 201 is rotated so that the internal thread is connected to the thread of another pipe body 1, after the position of the clamping ring 201 is confirmed, the limiting block 206 is embedded inside the card slot 101 by using the spring 205 to further position the clamping ring 201. At the same time, the limiting block 206 always maintains close contact with the card slot 101 under the elastic force of the spring 205, ensuring the stability of the connection, making the clamping ring 201 more stable when connected, and improving the service performance and practicality of the wire pipe.

[0029] In the embodiment of the present utility model, a support plate 207 is nested on the outer surface of the limit rod 202. The middle part of the support plate 207 is arc-shaped. The inner side of the support plate 207 is in contact with the outer side of the limit rod 202. A pulling rope is arranged between the limit rod 202 and the support plate 207. The support plate 207 nested on the outer surface of the limit rod 202 provides additional support for the limit rod 202. The middle part of the support plate 207 is arc-shaped, enabling the support plate 207 to better fit the outer surface of the limit rod 202. When the snap ring 201 is installed on the pipe body 1, the arc-shaped support plate 207 can adapt to the radian of the limit rod 202, thereby supporting the limit rod 202 and causing the limit rod 202 to drive the spring 205 and the limit block 206 into the interior of the snap ring 201. The pulling rope arranged between the limit rod 202 and the support plate 207 can prevent the support plate 207 from falling off the limit rod 202, making the support plate 207 more convenient to use. When the snap ring 201 is connected to the pipe body 1, the support plate 207 is separated from the limit rod 202. The limit block 206 is embedded into the interior of the card slot 101 by the elastic force of the spring 205, thereby further positioning the snap ring 201, further improving the stability of the snap ring 201 during use, and improving the quality and stability of the connection of the wire conduit.

[0030] Working principle: First, the pipe body 1 serves as the main body for protecting wires and cables. Its galvanized material provides good corrosion resistance and extends the service life. The card slots 101 on the outer surface of the pipe body 1 can cooperate with other accessories or fixing devices to ensure the stable position of the wire pipe. The threads at one end of the pipe body 1 are used for quick and firm connection with other wire pipes, ensuring tightness and stability. The inner threads of the two snap rings 201 in the connection group 2 enable them to be tightly nested on the outer surface of the pipe body 1 and are movably connected to the pipe body 1, facilitating installation and disassembly. During the connection process, the two snap rings 201 are spliced at the threaded end of the pipe body 1 and fixed by a bolt connection between the positioning blocks 203 at both ends. The limiting rod 202 passes through both ends of the snap ring 201 to enhance the connection stability and prevent the snap ring 201 from deforming or misaligning. The baffle 204 on the outer side of the limiting rod 202 prevents the limiting rod 202 from falling off and is convenient for operation. The spring 205 at one end of the limiting rod 202 can be embedded inside the snap ring 201 and is in a sliding connection, providing a pre-tightening force for the snap ring 201 to make the snap ring 201 fit more tightly against the pipe body 1 and improve the connection strength. When the spring 205 is in a compressed state, the limiting block 206 at the other end abuts against the inside of the snap ring 201 under the elastic force of the spring 205, enhancing the connection stability between the snap ring 201 and the pipe body 1. At the same time, when the snap ring 201 rotates to threadedly connect the internal thread with the thread of another pipe body 1 and the position is determined, the limiting block 206 can be embedded into the card slot 101 of the pipe body 1 to further accurately determine the position of the snap ring 201, ensuring a firm and accurate connection and guaranteeing the normal operation of the entire wire pipe system. The middle part of the support plate 207 nested on the outer surface of the limiting rod 202 is arc-shaped, and the inner side fits against the outer side of the limiting rod 202. During the installation process, the support plate 207 can provide additional support for the limiting rod 202, enabling it to drive the spring 205 and the limiting block 206 to smoothly enter the inside of the snap ring 201 and be embedded into the inside of the card slot 101, making the connection between the snap ring 201 and the pipe body 1 more stable. The pull rope prevents the support plate 207 from falling off the limiting rod 202, ensuring the convenience of using the support plate 207 and making the installation of the pipe body 1 more convenient and flexible. The coordinated action of each component realizes the effective protection, firm connection, and good fire resistance of the wires and cables, improving the safety and stability of the wire pipe during use.
