Detailed Description
Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present utility model, but it will be apparent to one skilled in the art that the present utility model may be practiced without these details.
As shown in fig. 1 to 3, the present embodiment provides a coffee machine piping assembly including a hose 1, a support tube 2, and a sleeve 3; the inside of the hose 1 is sleeved with a supporting tube 2, and the outside of the hose 1 is sleeved with a sleeve 3; the inside wall of sleeve 3 is equipped with the groove 31 of stepping down, and hose 1 receives the mutual extrusion of stay tube 2 and sleeve 3 and takes place deformation, and the deformation part embedding of hose 1 is stepping down in the groove 31. During assembly, the hose 1 is inserted into the sleeve 3, then the support tube 2 is inserted into the hose 1 from top to bottom, the hose 1 is deformed by extrusion of the sleeve 3 and the support tube 2, the deformed part is outwards expanded to be embedded into the yielding groove 31 of the sleeve 3, and accordingly the hose 1 is fixed, and the hose 1 is effectively prevented from falling off.
As shown in fig. 2 and 3, the upper end portion of the support tube 2 is provided with a flange 21, and the flange 21 is abutted against the upper end portion of the hose 1, so that the support tube 2 and the hose 1 can be better clamped and fixed, and the support tube 2 is prevented from sliding down.
As shown in fig. 1 to 3, in this embodiment, the inner side wall of the sleeve 3 is provided with a relief groove 31, and the deformed portion of the hose 1 is embedded in the relief groove 31, thereby forming a fixing structure similar to a convex ring. In other embodiments, a plurality of relief grooves 31 may be disposed at intervals on the inner side wall of the sleeve 3, or a plurality of annular grooves may be disposed in the same relief groove 31, so that the deformed portion of the hose 1 is uniformly embedded in the plurality of relief grooves 31 or the plurality of annular grooves, thereby forming a plurality of convex ring structures similar to threads, and further being better mutually matched and fixed with the sleeve 3.
As shown in fig. 1 to 3, the number of sleeves 3 in the present embodiment is one, and the length of the support tube 2 is longer than the length of the sleeve 3. In other embodiments, a plurality of sleeves 3 may be provided outside the corresponding hoses 1 of the support tube 2 at the same time, if desired.
As shown in fig. 2, in order to ensure that the hose deforms by pressing the support tube 2 and the sleeve 3 against each other, the outer diameter R of the hose 1 should be ensured during design 1 Is larger than the inner diameter r of the sleeve 3 1 And the inner diameter R of the hose 1 2 Smaller than the outer diameter r of the support tube 2 2 . Preferably, the outer diameter R of the hose 1 1 With the inner diameter r of the sleeve 3 1 The difference between 0.25-0.35mm; outer diameter r of support tube 2 2 With the inner diameter R of the hose 1 2 The difference between the two is controlled to be 0.13-0.25mm, and the diameter r of the relief groove 31 is set to be 3 With the outer diameter R of the hose 1 1 The difference between (2) and (45) should be controlled to be 0.2-0.45mm. However, in practical applications, the above values may be specifically set according to the deformation of the hose 1, which is only referred to herein and not madeIs the only limit of the protection scope.
After the assembly is completed, the outside of the sleeve 3 may be swaged again to more tightly fit the hose 1 fitted inside the sleeve 3 with the support tube 2, thereby further preventing the falling-off, as shown in fig. 4.
