[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a high-strength rubber hose, including a hose 1 and a hose 2, the hose 1 is a hose to be connected, the hose 2 is an extended hose, the hose 1 and the hose 2 are both rubber hoses, which can be used to transport liquids and can be cut at will, the right end of the hose 1 is equipped with a fixing component 3, the right end of the fixing component 3 is equipped with a connecting component 4 used in conjunction with the fixing component 3, the two sets of hoses can be connected by connecting the fixing component 3 and the connecting component 4, and the right end of the connecting component 4 is fixedly connected to the left end of the hose 2;

[0033] The fixing assembly 3 includes a fixing sleeve 31 for fixing the hose 1. The fixing sleeve 31 is inserted at the right end of the hose 1. Since the fixing sleeve 31 and the hose 1 are not fixedly connected, the operator can freely cut the hose 1 according to his own needs, so as to adapt to different usage conditions. The outer wall of the fixing sleeve 31 is sleeved with a nut 5 for fixing the fixing sleeve 31. The outer wall of the fixing sleeve 31 is provided with a fixing spring plate 33 for squeezing the outer wall of the hose 1. The fixing spring plate 33 and the fixing sleeve 31 are integrally formed and have elastic deformation ability. When squeezed, they can rotate downward. The fixing spring plate 33 and the outer wall of the fixing sleeve 31 are provided with an external thread 34 for connecting the fixing spring plate 33 and the nut 5. The nut 5 is adapted to the external thread 34. The nut 5 can be engaged with the external thread 34 by rotating the nut 5. At the same time, the nut 5 will squeeze the fixing spring plate 33 to make it rotate downward to squeeze the outer wall of the fixing sleeve 31.

[0034] Reference Figure 2 - Figure 3 The connecting assembly 4 includes a rotary block 43 for facilitating the operator to rotate the connecting assembly 4. The rotary block 43 is rotatably connected to the outer wall of the hose 2. The left end of the rotary block 43 is fixedly connected to a bolt column 41 for connecting the fixing assembly 3. The inner wall of the fixing sleeve 31 is provided with a connecting spring plate 35 for fixing the inner wall of the hose 1. The outer wall of the connecting spring plate 35 is provided with an internal thread 36 for driving the bolt column 41 to move. The bolt column 41 and the internal thread 36 are adapted to each other. By rotating the bolt column 41, the bolt column 41 can be driven to engage with the internal thread 36. At the same time, the bolt column 41 will squeeze the connecting spring plate 35 to make it rotate upward to squeeze the inner wall of the hose 1. The outer wall of the rotary block 43 is provided with a rubber block 42 for facilitating the operator to rotate the rotary block 43. A through groove for liquid to pass through is provided inside the bolt column 41. The through groove is connected to the hose 2. When the hose 2 is connected to the hose 1 through the bolt column 41, the liquid can directly flow from the inside of the hose 1 through the through groove into the inside of the hose 2.

[0035] Referring to the figure, the inner wall of the nut 5 is provided with a rubber block 51 for preventing the nut 5 from loosening. The rubber block 51 is set in a fin shape. The rubber block 51 is adapted to the rubber block 42. When the rubber block 51 rotates clockwise, the rubber block 51 will squeeze the rubber block 42 with an inclined surface, and when the nut 5 attempts to rotate in the opposite direction, the rubber block 51 will squeeze the rubber block 42 with a flat surface. In this way, the nut 5 cannot be easily loosened and is safer in use. The outer wall of the nut 5 is provided with an anti-slip groove for facilitating the operator to rotate the nut 5. The outer wall of the fixed sleeve 31 is provided with a limiting ring 32 for blocking the nut 5. The outer diameter of the limiting ring 32 is larger than the inner diameter of the nut 5. The limiting ring 32 can prevent the nut 5 from arbitrarily detaching from the outer wall of the fixed sleeve 31.

[0036] Working principle: During use, when it is necessary to adjust the length of hose 1, hose 1 can be directly cut to a suitable length according to the required requirements. After cutting, the fixing assembly 3 can be directly sleeved on the right end of hose 1, and then the rotary block 43 can be rotated to make the bolt column 41 engage with the internal thread 36. At the same time, the bolt column 41 will squeeze the connecting spring plate 35 to make it close to the inner wall of hose 1. When the left end of the rotary block 43 contacts the right end of the fixing sleeve 31, the rotation of the rotary block 43 can be stopped, and then the nut 5 can be rotated to engage with the external thread 34. At the same time, the nut 5 will squeeze the fixing spring plate 33 to make it rotate downward and tightly squeeze the outer wall of hose 1. When the right end of the nut 5 is flush with the right end of the rotary block 43, the nut 5 will not be able to continue to rotate. At this time, hose 1 and hose 2 are connected. At the same time, the rubber block 51 will also be blocked by the rubber block 42, making it difficult for the nut 5 to rotate in the opposite direction to ensure the stability of the connection between hose 1 and hose 2.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
