Description

Technical Field

[0001] The utility model belongs to the technical field of kettle accessories, and particularly relates to a spout of a mountaineering kettle. Background Art

[0002] Since mountaineering requires a lot of equipment, among which a sports kettle is a necessity for mountaineers. For the sports kettles currently used by mountaineers, in order to facilitate quick opening, a rubber plug or a kettle lid with a rubber plug is generally used to close the spout of the kettle. The spout of the kettle is relatively higher, and generally, the spout of the kettle and the kettle body are of an integral structure. In this way, after the spout of the kettle is used for a long time, it is not easy to clean and is not hygienic to use. Content of the Utility Model

[0003] The purpose of the utility model is to provide a spout of a mountaineering kettle for the above problems. The spout of the kettle is of a detachable structure, which is convenient for cleaning the spout of the kettle and is more hygienic to use.

[0004] The utility model is realized by the following technical solutions:

[0005] A spout of a mountaineering kettle includes a circular tubular main body. An annular first arc chamfer is provided at the upper port of the main body. An inclined guide surface with a larger upper opening and a smaller lower opening is provided between the first arc chamfer and the inner wall of the main body. An internal thread is provided at the lower part of the inner wall of the main body; an outwardly extending boss is provided at the lower end surface of the main body; an annular second arc chamfer is provided inside the boss, a circular inwardly concave notch is provided at the lower part of the outer side of the boss, and a third arc chamfer is provided at the upper part of the outer side of the boss.

[0006] Further, the first arc chamfer is an arc structure that is higher in the middle and lower at both sides and convex upward.

[0007] Further, an arc transition part is provided between the inwardly concave notch and the second arc chamfer.

[0008] Further, the height ratio of the part with the internal thread to the part without the internal thread on the inner wall of the main body is 3:1 to 1:1.

[0009] Further, the inclination angle of the inclined guide surface with respect to the vertical plane is 5 to 15 degrees.

[0010] The beneficial effects of the present utility model are as follows: The spout of the hiking kettle designed by the present utility model is a detachable structure, which can be directly added to an existing kettle and connected to the external thread of the inherent spout of the kettle through an internal thread; the upper end surface is provided with a smooth first arc chamfer, so that touching the mouth will not cause discomfort due to sharp edges, and the outside of the spout is smooth without threads, and stains will not be hidden in the thread gaps. The entire spout can be disassembled. Since the spout is a circular tubular hollow structure, it is easy to insert a brush from both ends for cleaning, so it is more hygienic to use. A concave notch is provided at the lower part of the spout, and a rubber plug connecting rope for closing the spout or a snap ring can be tied or snapped into it. Brief Description of the Drawings

[0012] Figure 2 is Figure 1 A-A cross-sectional view of.

[0013] In the figure, 1, main body part; 2, first arc chamfer; 3, inclined guiding surface; 4, internal thread; 5, boss; 6, concave notch; 7, second arc chamfer; 8, third arc chamfer. Detailed Embodiment

[0014] The present utility model will be further elaborated below in conjunction with specific examples and the accompanying drawings.

[0015] As Figure 1 , Figure 2 shown, a spout of a hiking kettle includes a circular tubular main body part 1. An annular first arc chamfer 2 is provided at the upper port of the main body part 1. The first arc chamfer 2 is an arc structure that is high in the middle and low on both sides and bulges upward. An inclined guiding surface 3 with a large upper opening and a small lower opening is provided between the first arc chamfer 2 and the inner wall of the main body part 1. The inclination angle of the inclined guiding surface 3 with respect to the vertical plane is 10 degrees. An internal thread 4 is provided at the lower part of the inner wall of the main body part 1. The height ratio of the part of the inner wall of the main body part 1 provided with the internal thread 4 to the part without the internal thread is 2:1. A boss 5 extending outward is provided at the lower end surface of the main body part 1; a second arc chamfer 7 is provided in a ring shape inside the boss 5, a concave notch 6 is provided in a ring shape on the lower part of the outside of the boss 5, and a third arc chamfer 8 is provided on the upper part of the outside of the boss 5. An arc transition part is provided between the concave notch 6 and the second arc chamfer 7.

[0016] The spout of the hiking kettle designed by the utility model is a detachable structure. When in use, the spout of the utility model is connected to the spout integral with the kettle through the internal thread 4. For some kettles with the spout plugged by a rubber stopper which needs to be connected by a rope or a loop, the loop can be first put on the spout integral with the kettle, and then the spout of the utility model is installed. The loop is clamped by the concave notch 6 to prevent it from slipping upwards. The rope can also be tied to the concave notch 6 to prevent it from slipping upwards as well. After the second arc chamfer 7 abuts against the kettle, the internal thread 4 is screwed tightly with the external thread of the kettle. The inclined guiding surface 3 on the upper part of the spout of the utility model is convenient for plugging the columnar rubber stopper into the spout to play a guiding role. The rubber stopper is plugged into the upper part of the main body 1 where there is no internal thread on the inner wall. When drinking water, the rubber stopper is taken out and then water can be drunk. The smooth first arc chamfer 2 will not cause discomfort when touching the mouth due to its edges and corners. The outside of the spout is smooth without threads, and stains will not hide in the thread gaps. After using for a period of time, the whole spout is disassembled. Since the spout is a circular tubular hollow structure, it is easy to insert a brush from both ends for cleaning, so it is more hygienic to use.

[0017] The above embodiments are only the relatively preferred embodiments of the utility model, which are only used to explain the utility model, rather than limiting the utility model. Any changes, substitutions, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principle of the utility model shall be equivalent replacement methods and shall be included in the protection scope of the utility model.
