[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A quick-release pipe for heating systems, such as Figures 1 to 8 As shown, it includes: a pipe 100, a first mating end ring 110 fixed at the end of the pipe 100, a second mating end ring 120 connected to the end face of the first mating end ring 110, and a mating assembly 200 assembled on the outer walls of the first mating end ring 110 and the second mating end ring 120.

[0028] The docking assembly 200 includes a collar 210 fixed to the outer wall of the first docking end ring 110. The outer wall of the collar 210 is rotatably provided with a driven ring 230. The end face of the driven ring 230 is fixed with an arc plate 250 extending into the second docking end ring 120. The end face of the second docking end ring 120 is provided with a first clearance groove 220 for the arc plate 250 to be inserted. The side wall of the first clearance groove 220 is reserved with a card slot 221. The side wall of the arc plate 250 is fixed with a card 251 that is inserted into the card slot 221.

[0029] The outer wall of the pipe 100 is fitted with a locking ring 270 that engages with the end face of the first docking end ring 110. The curved outer wall of the locking ring 270 is provided with multiple sets of ball-head rubber rods 280 that penetrate into the locking ring 270. A groove 130 is provided at the contact position between the curved outer wall of the pipe 100 and the end of the ball-head rubber rod 280. Multiple sets of protrusions 140 are fixed at equal intervals on the curved inner wall of the groove 130.

[0030] The end of the first mating end ring 110 is fixed with a conical ring 111 extending into the second mating end ring 120. A conical ring groove 121 is provided at the contact position between the end face of the second mating end ring 120 and the conical ring 111. Two sets of sealing rings 112 are assembled on the curved outer wall of the conical ring 111. An annular groove 122 that matches the sealing ring 112 is provided on the inner wall of the conical ring groove 121.

[0031] During docking, external forces in two directions are applied to the driven rings 230 on the outer walls of the first docking end ring 110 and the second docking end ring 120, causing them to rotate around the center of the first docking end ring 110 and the second docking end ring 120. When the arc plate 250 and the card 251 connected to the end face of the driven ring 230 are aligned with the first clearance groove 220, the two sets of first docking end rings 110 and second docking end rings 120 can be brought closer to each other. When the arc plate 250 is fully inserted into the first clearance groove 220, its card and the card slot 221 are also aligned, which can remove the external force applied to the two sets of driven rings 230. The driven rings 230 will rotate in the opposite direction to restore the original state, allowing the card 251 to enter the card slot 221. Since the rotation directions of the two sets of driven rings 230 are opposite, both sets of driven rings 230 will be tightly engaged with the first docking end ring 110 and the second docking end ring 120.

[0032] After the first mating end ring 110 and the second mating end ring 120 are mated, the conical ring 111 will enter the conical ring groove 121, and the sealing ring 112 will also enter the ring groove 122 to achieve the purpose of sealing, so as to prevent the liquid transported in the pipeline 100 from leaking from here.

[0033] During the installation of the heating pipe 100, some pipes will be in a vertical position. Therefore, it is necessary to cut grooves in the wall to lay the pipes 100. However, the vertical pipes 100 often tilt and cannot stand completely upright in the grooves cut in the wall. At this time, the locking ring 270 is slid out from the end faces of the first mating end ring 110 and the second mating end ring 120 respectively. Then, an external force is applied to the side away from the first mating end ring 110 and the second mating end ring 120, and the locking ring 270 will slide along the outer wall of the pipe 100. The ball-head rubber rod 280 slides in the inclined groove 130, and an outward squeezing force is applied to the ball-head rubber rod 280, causing the ball-head rubber rod 280 to gradually contact the groove opened in the wall. The protrusion 140 acts as a barrier to the ball-head rubber rod 280 after it moves and prevents it from moving in the opposite direction. Therefore, the ball-head rubber rod 280 will be in close contact with the groove opened in the wall, which serves to constrain the pipe 100 and make the pipe 100 stand stably in the groove opened in the wall, which facilitates the subsequent docking or burial of the pipe 100.

[0034] Please refer to this carefully. Figure 8A circular channel is provided inside the locking ring 270 at the contact position with the ball head rubber rod 280, and a constraint ring that is slidably disposed in the circular channel is fixed on the outer wall of the curved surface of the ball head rubber rod 280.

[0035] The travel of the ball head rubber rod 280 is constrained to prevent it from separating from the locking ring 270.

[0036] Please refer to this carefully. Figure 3 and Figure 4 A positioning ring groove is provided at the contact position between the curved outer wall of the collar 210 and the driven ring 230. A torsion spring is installed between the inner wall of the driven ring 230 and the positioning ring groove. An anti-slip sleeve 240 is fixed to the curved outer wall of the driven ring 230.

[0037] The torsion spring automatically reverses the rotation of the collar 210 after rotation, and the forces generated by the torsion springs at the first docking end ring 110 and the second docking end ring 120 are opposite, so the first docking end ring 110 and the second docking end ring 120 will be tightly locked together. With the assistance of the anti-slip sleeve 240, it is more convenient to apply external force to it by hand.

[0038] Please refer to this carefully. Figure 3 and Figure 4 The first docking end ring 110 and the second docking end ring 120 have a second clearance groove 260 that communicates with the positioning ring groove and allows the arc plate 250 to rotate.

[0039] This allows the arc plate 250 to rotate without obstruction, and it can rotate along with the driven ring 230, ultimately locking the two sets of mating end rings.

[0040] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
