[0030] Embodiment

[0031] As Figures 1-3 shown, this embodiment provides a hose dead - angle - free connection device, including: a hose 1, a clamping seat 2 provided at one end of the hose 1, and a locking cover 3 provided on the outer periphery of the hose 1. A protrusion 11 is provided at one end of the hose 1, and the protrusion 11 is fixedly connected to the end face of the clamping seat 2. The protrusion 11 makes the hose 1 and the clamping seat 2 closer together without leaving a gap, thereby preventing the hose 1 from accumulating liquid into the locking cover 3, having no dead - angle, and having good sealing performance.

[0032] Among them, the hose 1 includes: a clamping portion 12 installed between the clamping seat 2 and the locking cover 3, and a body portion 13 provided at one end of the clamping portion 12. The protrusion 11 is provided at one end of the body portion 13. The sealing performance of the hose 1 is ensured by the clamping portion 12 and the body portion 13.

[0033] At the same time, the outer diameter of the clamping portion 12 is the same as the outer diameter of the body portion 13, and the inner diameter of the clamping portion 12 is smaller than the inner diameter of the body portion 13. That is, it is necessary to ensure that the clamping portion 12 can be smoothly installed between the locking cover 3 and the clamping seat 2, and also ensure that the end face of the body portion 13 can just abut against the end face of the clamping seat 2.

[0034] In this embodiment, the protrusion 11 is provided on the end face of the body portion 13 close to the inner side of the clamping portion 12, that is, the protrusion 11 is provided inside the clamping portion 12 and is just installed on the end face where the body portion 13 and the clamping portion 12 are joined, so as to ensure the smooth installation of the protrusion 11.

[0035] In this embodiment, the inner side surface of the body portion 13 is flush with the inner side surface of the clamping seat 2, without dead angles, making the structures of the two more compact, without generating liquid accumulation, and not affecting the flow rate of the liquid accumulation in the hose 1, thereby ensuring the conveying efficiency of the hose 1.

[0036] In this embodiment, a positioning groove 21 for defining the position of the locking cover 3 is provided on the outer side of the clamping seat 2. The positioning groove 21 is used to install the locking cover 3, and the two are of a clamping structure, which is very convenient for installation and disassembly, and has a good fixing effect, ensuring the stability of the installation of the hose 1.

[0037] In this embodiment, a groove 22 adapted to the protrusion 11 is provided at the end of the clamping seat 2. The groove 22 is provided corresponding to the protrusion 11 to form a clamping structure, which can not only ensure the tight connection between the clamping seat 2 and the hose 1, play a sealing role, and not generate liquid accumulation, but also ensure the firmness between the two.

[0038] In this embodiment, the position of the positioning groove 21 should be such that the protrusion 11 can just be completely inserted into the groove 22, which can not only ensure the tight connection between the protrusion 11 and the groove 22, that is, the end surface of the clamping seat 2 is tightly connected to the end surface of the hose 1, that is, the clamping seat 2 fastens the hose 1 from the inner surface of the hose 1, but also ensure that the locking cover 3 fastens the hose 1 from the outer surface of the hose 1, so that the hose 1 is less likely to have liquid accumulation flowing out into the locking cover 3.

[0039] In this embodiment, the body portion 13 and the clamping portion 12 are integrally formed. Integral forming can complete the forming process of the hose 1 at one time, greatly shortening the production time, improving the production efficiency, having low cost, and reducing the production links, and can better control the quality of the hose 1, improve its production precision and repeatability, so as to ensure that the size and quality of each hose 1 are consistent, which is suitable for mass production.

[0040] In this embodiment, the cross-section of the locking cover 3 is "L" - shaped. One end of it is clamped in the positioning groove 21, and the other end is arranged on the outer surface of the hose 1. The space inside the "L" - shaped locking cover 3 can be used to install and lock the clamping portion 12. Combined with the fact that one end of the locking cover 3 is fixedly connected to the clamping seat 2, the two are used in cooperation to ensure the stable firmness of the hose 1.

[0041] Of course, the protrusion 11 is hemispherical, that is, the groove 22 is also hemispherical, so that the two are adapted to each other. Hemispherical protrusions 11 can usually simplify the assembly process because they can be easily connected to the clamping seat 2 by snap-fitting or screwing in without the need to use additional tools for fastening. The whole process is simple to operate, convenient to use, and reduces the use cost. Moreover, the hemispherical protrusions 11 increase the contact area with the clamping seat 2, making the connection between the hose 1 and the clamping seat 2 more firm and stable.

[0042] In addition, the hose 1 is threadedly connected to both the clamping seat 2 and the locking cover 3. The disassembly and assembly are simple, which is convenient for maintenance and repair, easy to use, and the fixing effect of the threaded connection is good, with good self-locking property, which can improve the connection safety and further ensure the sealing performance of the hose 1.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
