Description

Technical Field

[0001] This utility model relates to the field of EPDM pipe technology, and in particular to an EPDM pipe with good toughness. Background Technology

[0002] EPDM pipe usually refers to ethylene propylene diene monomer (EPDM) rubber pipe. It is a type of pipe made from EPDM rubber, which is a terpolymer of ethylene, propylene, and non-conjugated dienes. This rubber has many excellent properties, such as weather resistance, wear resistance, and aging resistance. As a result, EPDM pipe is widely used in many industries due to its excellent performance.

[0003] In practical applications, existing EPDM pipes need to be cut to the required length. This process requires skilled workers and is prone to uneven cross-sections, necessitating further cutting and material waste. Furthermore, existing EPDM pipes have poor toughness. Therefore, a more flexible EPDM pipe is needed to precisely cut the pipe to the required length, making it easier for workers to operate. Utility Model Content

[0004] The purpose of this utility model is to provide an EPDM pipe with good toughness, so as to solve the problem mentioned in the background art that in the actual use of EPDM pipe, it is necessary to cut the EPDM pipe to the required length. In this process, the skill requirements of the workers are high, and the cross-section of the EPDM pipe is not flat enough, which requires the EPDM pipe to be cut again, resulting in material waste.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The tube body, mounting assembly, and isolation assembly are all included. The mounting assembly is wrapped around the outside of the tube body, and the isolation assembly is located inside the mounting assembly.

[0008] The mounting assembly includes a fixing frame that fits onto the outside of the tube body;

[0009] The isolation assembly includes a partition, a mounting post, a mounting frame, a first spring, and a movable post; the partition is inserted inside the fixed frame, the mounting post is fixed to the outer surface of the partition, the mounting post is connected through the inside of the fixed frame, the mounting frame is fixed to the outer surface of the fixed frame, the first spring is fixed inside the mounting frame, the movable post is fixed to the outer surface of the first spring, and the movable post is connected through the inside of the mounting post.

[0010] Furthermore, a guide post is fixed to the outer surface of the movable post, and a rotating post is rotatably connected inside the bottom guide post. A limit block is inserted inside the rotating post and the top guide post.

[0011] Furthermore, a connecting plate is fixed to the outer surface of the limiting block, and a second spring is fixed to the outer surface of the connecting plate. The second spring is fixed inside the guide post located at the top.

[0012] Furthermore, the installation assembly also includes a support frame, a support plate, a limiting plate, and a fixing plate; the support frame is fixed to the outer surface of the fixing frame on one side, the support plate is fixed to the outer surface of the fixing frame on the other side, the limiting plate is fixed to the outer surface of the support plate and is snapped inside the support frame, and the fixing plate is fixed to the outer surface of the support plate.

[0014] Furthermore, the tube body includes an inner tube layer, a steel wire, and an outer covering layer, with the outer covering layer wrapping around the outside of the inner tube layer and the steel wire embedded inside the outer covering layer.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, by setting up an isolation component, allows for precise cutting of the EPDM pipe. First, an inward pressing force is applied to the two sets of guide columns, compressing the first spring. Then, the mounting column is passed through the fixed frame, allowing the partition to fully insert into the fixed frame. The force applied to the guide columns is then released. Under the elastic force of the first spring, the movable column passes through the mounting column and applies a pulling force to the connecting plate, causing the limiting block to disengage from the guide column. A flipping force is applied to the rotating column, causing it to rotate into the top guide column. The force applied to the connecting plate is then released. Under the elastic force of the second spring, the limiting block springs into the guide column and rotating column. Guided by the partition, the pipe can be cut. This solution accurately cuts the EPDM pipe to the required length. It is simple and easy for workers to operate. Furthermore, the design of embedding steel wire inside the outer coating greatly improves the overall strength and tensile strength of the pipe, thereby increasing its toughness and facilitating precise manual cutting of the EPDM pipe.

[0017] II. Based on the first beneficial effect, when the position of the fixing frame on the pipe surface needs to be changed with the cooperation of the installation components, first remove the nut from the screw surface, apply a pulling force to the limiting post so that the limiting post is removed from the inside of the support frame, then insert the screw back into the limiting post for fixation, apply a relative pulling force to the two sets of fixing frames to remove the fixing frames from the pipe surface, move them to the required position, align the limiting plate with the support frame, apply a pressing force to the two sets of fixing frames so that the support plate is inserted into the support frame, then remove the screw using the above method, insert the limiting post into the limiting plate and the support frame, and then fix it with the screw. This solution can not only fix the partition in the required position, but also protect the joint of the pipe body and maintain the normal use of the pipe body. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-3 As shown, this embodiment is an EPDM pipe with good toughness, comprising:

[0031] Pipe body 1, mounting assembly and isolation assembly, the mounting assembly is wrapped around the outside of pipe body 1, and the isolation assembly is located inside the mounting assembly;

[0032] The mounting components include a fixing frame 21, which is attached to the outside of the tube body 1;

[0033] The isolation assembly includes a partition 31, a mounting post 32, a mounting frame 33, a first spring 34, and a movable post 35; the partition 31 is inserted inside the fixed frame 21, the mounting post 32 is fixed to the outer surface of the partition 31 and extends through the interior of the fixed frame 21, the mounting frame 33 is fixed to the outer surface of the fixed frame 21 and the first spring 34 is fixed inside the mounting frame 33, the movable post 35 is fixed to the outer surface of the first spring 34 and extends through the interior of the mounting post 32;

[0034] The partition 31 serves as a guide, making the cutting of the tube 1 simpler and more precise. The mounting post 32 is used to fix the partition 31 inside the fixed frame 21. The mounting frame 33 is used to support and install the fixed frame 21, and in turn, support and install the first spring 34. The first spring 34 is used to change the position of the movable post 35. The movable post 35 is used to restrict the mounting post 32 to the desired position.

[0035] A guide post 36 is fixed on the outer surface of the movable post 35. A rotating post 37 is rotatably connected inside the bottom guide post 36. A limit block 391 is inserted inside the rotating post 37 and the top guide post 36.

[0036] The guide post 36 is used to change the position of the movable post 35, the rotating post 37 is used to restrict the guide post 36 to the desired position, and the limiting block 391 is used to stably fix the rotating post 37 inside the guide post 36.

[0037] A connecting plate 39 is fixed to the outer surface of the limiting block 391, and a second spring 38 is fixed to the outer surface of the connecting plate 39. The second spring 38 is fixed inside the top guide post 36.

[0038] The connecting plate 39 is used to change the position of the limiting block 391, and the second spring 38 is used to provide elastic force to the connecting plate 39. When the connecting plate 39 is not under force, the limiting block 391 can quickly spring back into the guide post 36 and the rotating post 37.

[0039] The pipe body 1 includes an inner pipe layer 11, a steel wire 12 and an outer covering layer 13. The outer covering layer 13 is wrapped around the outside of the inner pipe layer 11, and the steel wire 12 is embedded inside the outer covering layer 13.

[0040] The inner tube layer 11 is the inner structure of the tube body 1, which is in direct contact with the fluid inside the tube. The steel wire 12 can significantly improve the overall strength and tensile properties of the tube body 1, thereby improving the toughness of the tube body 1, making the tube body 1 less prone to deformation or damage when subjected to internal fluid pressure and external forces. The outer cladding layer 13 plays a protective role for the inner tube layer 11, preventing the inner tube layer 11 from being corroded or worn by the external environment.

[0041] Working principle: When the tube body 1 needs to be cut, firstly, an inward pressing force is applied to the two sets of guide posts 36, so that the first spring 34 is in a compressed state. Then, the mounting post 32 is passed through the fixed frame 21, so that the partition plate 31 is fully inserted into the fixed frame 21. The force applied to the guide post 36 is removed. Under the elastic force of the first spring 34, the movable post 35 passes through the mounting post 32 and applies a pulling force to the connecting plate 39, causing the limiting block 391 to disengage from the guide post 36. A flipping force is applied to the rotating post 37, so that the rotating post 37 rotates into the top guide post 36. The force applied to the connecting plate 39 is removed. Under the elastic force of the second spring 38, the limiting block 391 springs into the guide post 36 and the rotating post 37. Under the guidance of the partition plate 31, the tube body 1 can be cut.

[0042] This step precisely cuts the EPDM pipe to the required length, and it is simple and easy for workers to operate.

[0043] Please see Figure 1 , Figure 2 and Figure 4 As shown, this embodiment, based on the above embodiment, also includes an installation component. The installation component includes a support frame 22, a support plate 23, a limiting plate 24, and a fixing plate 25. The support frame 22 is fixed to the outer surface of one side of the fixing frame 21, the support plate 23 is fixed to the outer surface of the other side of the fixing frame 21, the limiting plate 24 is fixed to the outer surface of the support plate 23 and is snapped inside the support frame 22, and the fixing plate 25 is fixed to the outer surface of the support plate 23.

[0044] The support frame 22 is used to connect with the limiting plate 24, thereby connecting the two sets of fixed frames 21 together. The support plate 23 is used to support and install the fixed frame 21, and then support and install the limiting plate 24. The fixed plate 25 is used for the screw 28 to move inside it.

[0045] A limiting post 26 is connected through the support frame 22 and the limiting plate 24. A connecting hole 27 is provided inside the limiting post 26. A screw 28 is connected through the fixing plate 25 and the connecting hole 27. A nut 29 is threaded onto the outer surface of the screw 28.

[0046] The limiting post 26 is used to restrict the limiting plate 24 inside the support frame 22. The connecting hole 27 can restrict the limiting post 26 to different positions. The screw 28 is used to connect the fixing plate 25 and the limiting post 26. With the cooperation of the nut 29, the fixing frame 21 can be fixed in the required position.

[0047] Working principle: When it is necessary to change the position of the fixing frame 21 on the surface of the tube body 1, first remove the nut 29 from the surface of the screw 28, apply a pulling force to the limiting post 26 so that the limiting post 26 is removed from the inside of the support frame 22, and then insert the screw 28 back into the limiting post 26 for fixation. Apply a relative pulling force to the two sets of fixing frames 21 to remove the fixing frames 21 from the surface of the tube body 1. After moving to the required position, align the limiting plate 24 with the support frame 22, apply a pressing force to the two sets of fixing frames 21 so that the support plate 23 is inserted into the support frame 22. Then, use the above method to remove the screw 28, and then insert the limiting post 26 into the limiting plate 24 and the support frame 22, and finally fix it with the screw 28.

[0048] This step not only fixes the partition 31 in the required position, but also protects the joint of the pipe body 1, ensuring the normal use of the pipe body 1.
