Description

Technical Field

[0001] This utility model relates to the field of prefabricated water tanks, and in particular to a prefabricated water tank tie rod threaded anti-corrosion component structure. Background Technology

[0002] Prefabricated water tanks are assembled from multiple prefabricated tank panels using bolting or welding. They offer advantages such as convenient installation and the ability to customize sizes and shapes to meet specific needs. In prefabricated water tanks, tie rods play a crucial structural support role. To prevent corrosion of the tie rod threads, specialized anti-corrosion components are typically designed. These components generally include an anti-corrosion sleeve that fits over the tie rod threads. The inner wall of the sleeve may have spiral protrusions that fit tightly against the studs, or other sealing structures may be used to prevent corrosive media such as moisture from contacting the threads. Some prefabricated tanks also incorporate fixing devices such as clamps on the outer wall of the sleeve, using specific connection methods to securely connect the sleeve to the studs, ensuring the anti-corrosion effect and structural stability of the tie rods, and extending the service life of the prefabricated water tank.

[0003] However, the current structure of the tie rod threaded anti-corrosion parts has some defects: Insufficient fastening stability: Small vibrations during water tank operation can easily cause the threaded rings and studs to loosen, failing to guarantee structural stability, affecting the reliability of the tie rod connection, and threatening the overall structural safety of the water tank. Poor sealing adaptability: It is difficult to adapt to uneven sealing surfaces, deformation, and water tank displacement, resulting in poor sealing effect and lack of buffering, which can easily damage the sealing parts and shorten the life of the sealing components; In response to this technical problem, this application proposes a prefabricated water tank tie rod threaded anti-corrosion component structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated water tank tie rod threaded anti-corrosion component structure. This structure aims to prevent the screw rings and studs from loosening due to minor vibrations during water tank operation, thereby improving structural stability and sealing performance. It can adapt to unevenness, deformation, or minor displacement of the sealing surface during operation, maintaining good sealing performance while also acting as a buffer to reduce damage to the sealing parts and extend the service life of the sealing components.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A prefabricated water tank tie rod threaded anti-corrosion component structure includes a screw rod, one end of which is connected to a tie rod, and the other end of which is threaded to a stud. A threaded ring is threaded to the outer wall of the screw rod, and multiple fixing rods are fixedly connected to the outer wall of the threaded ring. Protective rings are fixedly connected to the ends of the fixing rods. The protective rings and studs are connected by a positioning assembly to fix the studs and threaded rings. Inflatable sealing rings are provided at both ends inside the protective rings. An air inlet pipe is fixedly connected inside the air inlet pipe, which is sealed by a sealing assembly. An inflation assembly is also provided inside the air inlet pipe to inflate the air inlet sealing rings.

[0006] Furthermore, the positioning assembly includes two snap-fit ​​plates rotatably connected to the outer wall of the protective ring, a disc is fixedly connected to the outer wall of the stud, and two snap-fit ​​pins are fixedly connected to one side of the snap-fit ​​plate.

[0007] Furthermore, a buckle ring is fixedly connected to the outer wall of the buckle post, and a buckle groove is provided on the outer wall of the disc, with both the buckle post and the buckle ring engaging inside the buckle groove.

[0008] Furthermore, the sealing assembly includes a telescopic rod fixedly connected inside the air intake pipe, a sealing plug fixedly connected to the end of the telescopic rod, and a sealing cap threadedly connected to the end of the air intake pipe.

[0009] Furthermore, a spring is fitted on the outer wall of the telescopic rod, with one end of the spring connected to one side of the sealing plug and the other end of the spring connected to the inside of the air intake pipe.

[0010] Furthermore, the inflation assembly includes an inflation tube disposed inside the air inlet pipe, one end of the inflation tube being externally connected to an electric air pump, and the other end of the electric air pump abutting against one side of the sealing plug.

[0011] Furthermore, a sealing plate is fixedly connected to the outer wall of the inflation tube, and multiple round holes are opened on the outer walls of the air inlet tube, the inflation tube, and the sealing plug.

[0012] This utility model has the following beneficial effects: In this invention, the buckle plate is rotated to engage the buckle post and buckle ring into the buckle groove, thereby fixing the disc and connecting the stud and the protective ring together. Since the thread direction between the screw and the ring is opposite to the thread direction between the stud and the water tank, the ring and the stud are mutually fixed, thus preventing the ring and the stud from rotating and loosening due to minor vibrations during water tank operation, and improving the stability of the structure.

[0013] In this invention, an inflatable sealing ring is used to fit more tightly to the sealing surface, improving the sealing effect. It can also adapt to unevenness or deformation of the sealing surface or slight displacement of the water tank during operation by its own expansion and deformation, maintaining good sealing performance. In addition, it plays a buffering role, absorbing the impact force generated by water fluctuations and equipment vibrations in the water tank, reducing damage to the sealing parts and extending the service life of the sealing components.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3This utility model provides an embodiment of an assembled water tank tie rod threaded anti-corrosion component structure, including a screw rod 2, one end of which is connected to a tie rod 1, and the other end of which is threadedly connected to a stud 4. The tie rod thread is installed onto the water tank by threading the stud 4 onto the water tank. A threaded ring 12 is threaded onto the outer wall of the screw rod 2. The thread direction between the screw rod 2 and the threaded ring 12 is opposite to the thread direction between the stud 4 and the water tank. (Refer to...) Figure 3 and Figure 4 Multiple fixing rods 11 are fixedly connected to the outer wall of the screw ring 12. Protective rings 10 are fixedly connected to the ends of the fixing rods 11. The protective rings 10 and the stud 4 are connected by a positioning assembly, which fixes the stud 4 and the screw ring 12. Inflatable sealing rings 13 are provided at both ends inside the protective ring 10 to seal the structure. An air inlet pipe 7 is fixedly connected inside the air inlet pipe 13, which inflates the air inlet sealing ring 13 by delivering gas into it. Figure 5 The outer wall of the protective ring 10 is rotatably connected to two snap-fit ​​plates 3. The outer wall of the stud 4 is fixedly connected to a disc 5. Two snap-fit ​​pins 14 are fixedly connected to one side of the snap-fit ​​plate 3. The outer wall of the snap-fit ​​pin 14 is fixedly connected to a snap-fit ​​ring 15. The outer wall of the disc 5 is provided with a snap-fit ​​groove. The snap-fit ​​pins 14 and snap-fit ​​rings 15 are both engaged in the snap-fit ​​groove. By rotating the snap-fit ​​plate 3, the snap-fit ​​pins 14 and snap-fit ​​rings 15 are engaged in the snap-fit ​​groove, thereby fixing the disc 5 and connecting the stud 4 and the protective ring 10 together. Since the thread direction between the screw 2 and the screw ring 12 is opposite to the thread direction between the stud 4 and the water tank, the screw ring 12 and the stud 4 are mutually fixed, thereby avoiding the problem of the screw ring 12 and the stud 4 rotating and loosening due to the small vibrations generated by the water tank during operation, thus improving the stability of the structure. Both ends of the tie rod 1 have the above structure.

[0018] Reference Figure 1 , Figure 4 and Figure 6A telescopic rod 16 is fixedly connected inside the intake pipe 7. A sealing plug 18 is fixedly connected to the end of the telescopic rod 16. A sealing cap 6 is threadedly connected to the end of the intake pipe 7. The intake pipe 7 is sealed by screwing the sealing cap 6 onto it through the threaded connection, preventing external objects from entering the intake pipe 7 and affecting its internal structure. A spring 17 is fitted on the outer wall of the telescopic rod 16. One end of the spring 17 is connected to one side of the sealing plug 18, and the other end of the spring 17 is connected to the inside of the intake pipe 7. The spring 17 causes the sealing plug 18 to return to its original position, thus blocking the round hole. This seals the air inlet pipe 7 to prevent gas from escaping. An inflation pipe 8 is installed inside the air inlet pipe 7. One end of the inflation pipe 8 is connected to an electric air pump 9, and the other end of the electric air pump 9 is abutted against one side of the sealing plug 18. A sealing plate 19 is fixedly connected to the outer wall of the inflation pipe 8. Multiple round holes are opened on the outer walls of the air inlet pipe 7, the inflation pipe 8, and the sealing plug 18. The electric air pump 9 delivers gas to the inflation pipe 8, and then the gas passes through the round holes in sequence through the inflation pipe 8, the sealing plug 18, and the air inlet pipe 7, and finally enters the inflation sealing ring 13, thereby inflating the inflation sealing ring 13.

[0019] Working principle: First, the screw ring 12 is threaded onto the outer wall of the screw rod 2. Then, the stud 4 is threaded onto the end of the screw rod 2. Next, the stud 4 is threaded onto the water tank, thus connecting the tie rod 1 to the water tank. Then, the locking plate 3 is rotated to engage the locking stud 14 and locking ring 15 into the locking groove, thereby fixing the disc 5 and connecting the stud 4 and the protective ring 10 together. When the water tank vibrates, the stud 4, without the above design, would rotate due to vibration, causing it to detach from the water tank and the tie rod 1 to fall off. With the above design, the thread direction of the stud 4 is opposite to that of the screw ring 12, resulting in… When the stud 4 rotates, the screw ring 12 cannot rotate in the same direction, causing the stud 4 to remain stationary. This creates a paradox between the stud 4 and the screw ring 12, preventing the stud 4 from detaching from the water tank. The screw ring 12 also works on this principle to prevent it from falling off. Then, the inflation tube 8 is inserted into the air inlet tube 7, and it is brought into contact with the sealing plug 18. The inflation tube 8 is then slowly pushed to move the sealing plug 18 into the air inlet tube 7, exposing the round hole in the air inlet tube 7. The electric air pump 9 is then activated to deliver gas into the inflation tube 8. The gas then passes through the round hole sequentially through the inflation tube 8, the sealing plug 18, and the air inlet tube 7, finally entering the water tank. In the inflatable sealing ring 13, the sealing plate 19 temporarily blocks the air inlet pipe 7 to prevent gas from escaping from the gap between the inflation pipe 8 and the air inlet pipe 7, thus affecting the inflation efficiency. This allows the inflatable sealing ring 13 to inflate, causing it to expand and tightly adhere to the sealing surface, forming a seal. After inflation, the inflatable sealing ring 13 can automatically adjust according to the shape and pressure changes of the sealing surface, evenly adhering to the sealing surface, effectively improving the sealing effect and reducing the possibility of leakage. For unevenness or deformation of the sealing surface, or minor displacement of the water tank during operation, the inflatable sealing ring 13 can adapt through its own expansion and deformation. To maintain good sealing performance, the internal inflation chamber acts as a buffer, absorbing the impact of water fluctuations and equipment vibrations in the water tank, reducing damage to the sealing parts, and extending the service life of the seals. After inflation, the inflation tube 8 is pulled out from the air inlet tube 7. At this time, the sealing plug 18 is reset under the action of the spring 17, so that the sealing plug 18 blocks the round hole, thereby sealing the air inlet tube 7 and preventing gas from escaping. Then, the sealing cover 6 is screwed onto the air inlet tube 7 through a threaded connection to seal the air inlet tube 7 and prevent external objects from entering the air inlet tube 7 and affecting the internal structure, thus completing the installation of the entire anti-corrosion component structure.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
