Description

Technical Field

[0001] The utility model belongs to the technical field of rubber hoses, and particularly relates to a high-viscosity manual white glue hose. Background Art

[0002] After the high-viscosity white glue hose is opened for use, the white glue is likely to solidify at the position of the hose nozzle, forming a hard block at the end or solidifying on the inner wall of the nozzle. Moreover, the closer to the outlet position, the easier it is to have the phenomena of solidification and hardening, thus affecting the use of the white glue. Summary of the Invention

[0003] The purpose of the utility model is to address the above problems existing in the prior art and propose a high-viscosity manual white glue hose, which has the characteristic of reducing the possibility of forming a hard block at the nozzle or solidifying on the inner wall of the nozzle.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] A high-viscosity manual white glue hose includes: a hose body and a hose cap. The hose body has a discharge pipe, and the outer wall of the discharge pipe has a threaded portion. The hose cap is matched with the threaded portion to close the discharge pipe. A flexible rubber protrusion is provided in the middle of the hose cap. The rubber protrusion can be inserted into the channel of the discharge pipe and abuts against the inner wall of the discharge pipe.

[0006] In the above high-viscosity manual white glue hose, the hose cap has an internal thread adapted to the threaded portion. The end of the rubber protrusion corresponds to the middle position of the internal thread. In the initial connection state between the rubber protrusion and the discharge pipe, the rubber protrusion does not enter the discharge pipe. In the fully connected state between the rubber protrusion and the discharge pipe, the rubber protrusion is located inside the discharge pipe and abuts against the inner wall of the discharge pipe.

[0007] In the above high-viscosity manual white glue hose, the end of the rubber protrusion has a guiding surface. The diameter of the rubber protrusion is larger than the diameter of the inner channel of the discharge pipe, and the distance between the end faces of the rubber protrusion is smaller than the diameter of the inner channel of the discharge pipe.

[0008] In the above high-viscosity manual white glue hose, there is a gap between the outer peripheral wall of the rubber protrusion and the inner wall of the channel of the discharge pipe.

[0009] In the above high-viscosity manual white glue hose, a reinforcing rod is provided in the middle part of the hose cap, and at least part of the reinforcing rod is arranged inside the rubber protrusion so that the rubber protrusion wraps around the reinforcing rod.

[0010] In the above-mentioned high-viscosity manual white glue hose, a connecting portion is provided on the reinforcing rod. The connecting portion is arranged around the reinforcing rod and forms a gap with the inner bottom of the pipe cap, and the rubber protrusion covers the connecting portion.

[0011] Compared with the prior art, the present application has the following advantages:

[0012] In the present application, when high-viscosity manual white glue is needed, the pipe cap is unscrewed. At this time, the pipe cap is separated from the threaded portion on the outer wall of the discharge pipe of the pipe body. During use, the white glue flows out from the channel of the discharge pipe. After use, the pipe cap is screwed back. The flexible rubber protrusion in the middle of the pipe cap is inserted into the channel of the discharge pipe and closely abuts against the inner wall of the discharge pipe, playing a role in closing the discharge pipe to prevent the white glue from flowing out or air from entering the pipe.

[0019] The following further describes the present application in conjunction with the attached Figures 1 - 3 drawings and specific embodiments:

[0020] First of all, it should be noted here that in the description of this application, when terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other orientation words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings. It is only for the convenience of description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation to this application; in addition, when terms such as "first", "second", "third" and other numerical quantifiers appear, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, when terms such as "installation", "connection", "connection" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limit connections, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] As Figures 1 to 3 Shown in the figure, a high-viscosity manual white glue hose includes: a hose body 2 and a hose cap 3. The hose body 2 has a discharge pipe 21, and the outer wall of the discharge pipe 21 has a threaded portion 211. The hose cap 3 is fitted with the threaded portion 211 to close the discharge pipe 21. A flexible rubber protrusion 31 is provided in the middle of the hose cap 3. The rubber protrusion 31 can be inserted into the channel of the discharge pipe 21 and abuts against the inner wall of the discharge pipe 21.

[0022] In this application, when high-viscosity manual white glue is needed, the hose cap 3 is unscrewed. At this time, the hose cap 3 is disengaged from the threaded portion 211 on the outer wall of the discharge pipe 21 of the hose body 2. During use, the white glue flows out from the channel of the discharge pipe 21. After use, the hose cap 3 is screwed back. The flexible rubber protrusion 31 in the middle of the hose cap 3 is inserted into the channel of the discharge pipe 21 and tightly abuts against the inner wall of the discharge pipe 21, playing a role in closing the discharge pipe 21 and preventing the white glue from flowing out or air from entering the pipe.

[0023] The hose cap 3 and the discharge pipe 21 are fitted through the threaded portion 211. Coupled with the flexible rubber protrusion 31 inserted into the channel of the discharge pipe 21 and abutting against the inner wall, the double sealing measures greatly improve the sealing performance of the hose and can effectively prevent the white glue from volatilizing and drying out, affecting the quality of the white glue.

[0024] Specifically, the hose cap 3 has an internal thread 32 adapted to the threaded portion 211. The end of the rubber protrusion 31 corresponds to the middle position of the internal thread 32. In the initial connection state of the rubber protrusion 31 and the discharge pipe 21, the rubber protrusion 31 does not enter the discharge pipe 21. In the fully connected state of the rubber protrusion 31 and the discharge pipe 21, the rubber protrusion 31 is located inside the discharge pipe 21 and the rubber protrusion 31 abuts against the inner wall of the discharge pipe 21.

[0025] In the preliminary connection state, although the rubber protrusion 31 does not enter the discharge pipe 21, the internal thread 32 of the pipe cap 3 has started to cooperate with the threaded portion 211 on the outer wall of the discharge pipe 21, playing a certain positioning role. During the subsequent tightening process, until the fully connected state, the rubber protrusion 31 is located inside the discharge pipe 21 and abuts against the inner wall of the discharge pipe 21, squeezing the white glue inside the nozzle of the discharge pipe 21 back into the pipe body 2, preventing the white glue from remaining on the inner wall of the nozzle of the discharge pipe 21.

[0026] Specifically, the end of the rubber protrusion 31 has a guiding surface 311, the diameter of the rubber protrusion 31 is larger than the diameter of the inner channel of the discharge pipe 21, and the distance between the end faces of the rubber protrusion 31 is smaller than the diameter of the inner channel of the discharge pipe 21.

[0027] Since the diameter of the rubber protrusion 31 is larger than the diameter of the inner channel of the discharge pipe 21, when the pipe cap 3 is tightened and the rubber protrusion 31 enters the discharge pipe 21, the rubber protrusion 31 will be deformed by the extrusion of the inner wall of the discharge pipe 21. This deformation makes the contact between the rubber protrusion 31 and the inner wall of the discharge pipe 21 closer, thus greatly enhancing the sealing effect and effectively removing the residue on the inner wall of the inner channel of the discharge pipe 21.

[0028] Specifically, there is a gap between the outer peripheral wall of the rubber protrusion 31 and the inner wall of the channel of the discharge pipe 21.

[0029] Specifically, a reinforcing rod 33 is provided in the middle part of the pipe cap 3, and at least part of the reinforcing rod 33 is arranged inside the rubber protrusion 31 so that the rubber protrusion 31 wraps around the reinforcing rod 33.

[0030] The provision of the reinforcing rod 33 and part of it being located inside the rubber protrusion 31, making the rubber protrusion 31 wrap around the reinforcing rod 33, greatly enhances the structural strength of the rubber protrusion 31. During the connection and sealing process between the pipe cap 3 and the discharge pipe 21, the rubber protrusion 31 needs to bear a certain amount of pressure and friction. With the support of the reinforcing rod 33, the rubber protrusion 31 is not easily deformed or damaged.

[0031] Specifically, a connecting portion 331 is provided on the reinforcing rod 33. The connecting portion 331 is arranged around the reinforcing rod 33 and forms a gap with the inner bottom of the pipe cap 3, and the rubber protrusion 31 covers the connecting portion 331.

[0032] The connection strength between the rubber protrusion 31 and the reinforcing rod 33 and the connecting portion 331 is better, preventing the rubber protrusion 31 from falling off.

[0033] It should be noted that the above embodiments are only used to illustrate the present application and do not limit the technical solutions described in the present application. Although the present specification has described the present application in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify the present application or make equivalent substitutions, and all technical solutions and their improvements that do not depart from the spirit and scope of the present application should be covered within the scope of the claims of the present application.
