Description

Technical Field

[0001] The utility model belongs to the technical field of rotary joints, and particularly relates to a novel connecting structure for an embossing wheel. Background Art

[0002] The water inlet joint or the water outlet joint at the end of the embossing wheel is connected to the water inlet pipe or the water outlet pipe through a rotary joint to realize the circulation of hot water inside the embossing wheel for heating. Usually, screw threads are provided inside the water inlet joint and the water outlet joint for direct connection with the rotary joint. However, after a long time, it is easy to rust, resulting in poor sealing and leakage. Also, due to rusting, it is difficult to disassemble and replace the rotary joint. Content of the Utility Model

[0003] The purpose of the utility model is to provide a novel connecting structure for an embossing wheel to solve the problem of difficult disassembly and replacement at present.

[0004] The technical solution adopted by the utility model is a novel connecting structure for an embossing wheel, which includes an embossing wheel joint and a rotary joint. A step is arranged near the end inside the embossing wheel joint. A plurality of threaded connection holes are evenly spaced circumferentially on the end face of the embossing wheel joint. A flange one is provided at the head end of the rotary joint. A connecting head is provided at the outer end of the flange one to match the step. Threaded fixing holes corresponding to the threaded connection holes are provided on the flange one. Bolts are used to connect the flange one and the embossing wheel joint through the threaded connection holes and the threaded fixing holes.

[0005] Preferably, a sealing gasket is provided at the connection between the connecting head and the step.

[0006] Preferably, the number of the threaded connection holes is 4.

[0007] Preferably, the tail end of the rotary joint is connected to a pipe joint through a flange two. The pipe joint is connected to a pipe, and the pipe is arranged upward.

[0008] Preferably, a filter screen is detachably installed inside the rotary joint.

[0009] Preferably, a clamping plate is provided on the inner wall of the rotary joint. Installation holes are evenly spaced circumferentially on the clamping plate. Clamping joints are provided on the filter screen near the outer edge corresponding to the installation holes. The clamping joints are in interference fit with the installation holes to form a clamping connection.

[0010] Preferably, an ear plate is provided below the pipe joint, and a through hole is provided on the ear plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows. By transforming the embossing wheel joint into a stepped + threaded connection hole and connecting the embossing wheel joint to the head end of the rotary joint through flange one threaded connection, it is convenient for installation and disassembly, effectively solving the problem that it is difficult to disassemble the joint due to rusting when the rotary joint directly uses threaded connection to connect the embossing wheel joint. Among them, a filter screen is installed inside the rotary joint, which is beneficial to filtering impurities in the water body, improving the cleanliness inside the embossing wheel. And the tail end of the rotary joint is connected to the pipeline joint through flange two. On the one hand, it is convenient to disassemble, replace and clean the filter screen. On the other hand, the rotary joint can be connected in sections, reducing the installation weight of the joint and improving the installation convenience of the equipment.

[0015] The following will further explain and illustrate the present utility model in conjunction with the drawings of the specification, so as to facilitate better understanding by those skilled in the art.

[0016] Embodiment 1

[0017] As Figures 1-3 shown, a new type of embossing wheel connection structure includes an embossing wheel joint 1 and a rotary joint 2. A step 3 is arranged near the end inside the embossing wheel joint 1, and a plurality of threaded connection holes 4 are evenly spaced circumferentially on the end face of the embossing wheel joint 1. A flange one 5 is provided at the head end of the rotary joint 2. A connecting head 6 is provided at the outer end of the flange one 5 to match the step 3. A conduit is connected to the connecting head 6 and extends into the embossing wheel to separate the inlet water and the outlet water. Threaded fixing holes 7 corresponding to the threaded connection holes 4 are provided on the flange one 5. Bolts are used to connect the flange one 5 and the embossing wheel joint 1 through the threaded connection holes 4 and the threaded fixing holes 7. During installation, the rotary joint 2 is directly aligned with the embossing wheel joint 1. When the connecting head 6 abuts against the step 3, the flange one 5 abuts against the end face of the embossing wheel joint 1, and bolts are used for fastening. When disassembling, loosen the bolts and remove the rotary joint 2, effectively solving the problem that it is difficult to disassemble the joint due to rusting when the rotary joint 2 directly uses threaded connection to connect the embossing wheel joint 1.

[0018] In order to improve the sealing performance, a sealing gasket 8 is provided at the connection between the connecting head 6 and the step 3.

[0019] Furthermore, the number of the threaded connection holes 4 is 4, which not only ensures the connection firmness but also is convenient for operation.

[0020] Further, a filter screen 9 is detachably installed inside the rotary joint 2. A clamping plate 201 is provided on the inner wall of the rotary joint 2. Mounting holes are circumferentially spaced on the clamping plate 201. Clamping joints 901 are provided on the filter screen 9 corresponding to the mounting holes near the outer edge. The clamping joints 901 are in interference fit with the mounting holes to form a clamping connection. The filter screen 9 is used to filter impurities in the water body, improving the cleanliness inside the embossing wheel.

[0021] The tail end of the rotary joint 2 is connected to a pipe joint 11 through a second flange 10. The pipe joint 11 is connected to a pipe 12. The pipe 12 is arranged upward. An ear plate 13 is provided below the pipe joint 11, and a through hole is opened on the ear plate 13. The tail end of the rotary joint 2 is connected to the pipe joint 11 through the second flange 10. On the one hand, it is convenient to disassemble, replace and clean the filter screen 9. On the other hand, the rotary joint 2 can be connected in sections, reducing the installation weight of the joint and improving the installation convenience of the equipment. Among them, the pipe 12 is arranged upward to prevent the pipe from interfering with other equipment from below and is conducive to the water body entering the rotary joint.

[0022] The embodiments described above are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit and principles of the present invention, various deformations and improvements made by those skilled in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
