[0030] 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.

[0031] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a rubber hose with a quick-release connector, comprising a connecting pipe 2, a connecting plate 3 is fixedly connected to the upper surface of the connecting pipe 2, a locking component 5 is provided at the right end of the connecting plate 3, and a fixing component 4 is provided on the right surface of the connecting pipe 2;

[0032] The fixing assembly 4 includes a guide plate 43, the left surface of the guide plate 43 is rotatably connected to the right surface of the connecting pipe 2, the right surface of the guide plate 43 is rotatably connected to the fixing plate 42, and the fixing plate 42 is fixedly connected to the right end of the lower surface of the connecting plate 3. An arc groove 1 47 is provided on the right surface of the guide plate 43, and an arc groove 2 48 is provided on the front side of the right surface of the guide plate 43 adjacent to the arc groove 1 47. The arc groove 1 47 and the arc groove 2 48 both have a certain slope and are inclined toward the center of the guide plate 43. However, when the guide plate 43 is rotated, the arc groove 1 47 will move the clamping plate 1 41 toward the outer wall of the pipe 1 through its own slope, and the arc groove 2 48 will drive the clamping plate 2 45 to contact the inner wall of the pipe 1 through its own slope, thereby ensuring that the inner and outer walls of the pipe 1 are subjected to force at the same time, thereby improving the stability of the connection.

[0033] Reference Figure 2 , Figure 3 The locking assembly 5 includes a threaded rod 51. The threaded rod 51 is a prior art and has the characteristics of self-locking up and down, which ensures that the threaded rod 51 will not rotate and ensures the stability of the fixation. The threaded rod 51 is threadedly connected to the right end of the upper surface of the connecting plate 3. The lower surface of the threaded rod 51 is rotatably connected with a concave block 52. The front and rear lengths of the concave block 52 and the positioning block 53 are consistent to ensure the accuracy of positioning. A rectangular groove 55 is provided on the lower surface of the right end of the connecting plate 3, and the concave block 52 is slidably connected to the inner wall of the rectangular groove 55.

[0034] Reference Figure 2 A round rod 44 is slidably connected to the inner wall of the arc groove 47, and a clamp plate 41 is fixedly connected to the right surface of the round rod 44. The lower surface of the clamp plate 41 contacts the pipe 1. There are multiple groups of round rods 44, and the left ends of the multiple groups of round rods 44 are slidably connected to the inner wall of the arc groove 48. The right surfaces of the multiple groups of round rods 44 are fixedly connected to the clamp plate 45, and the front surface of the clamp plate 45 contacts the inner wall of the pipe 1. The right surface of the fixed plate 42 is provided with through grooves 46, and there are multiple groups of through grooves 46. The through grooves 46 ensure that the multiple groups of round rods 44 can only move in a straight line, thereby ensuring the accuracy of clamping. The round rods 44 penetrate and slide on the inner wall of the through grooves 46.

[0035] Reference Figure 2 , Figure 3The inner wall of the concave block 52 is elastically connected with the positioning block 53 through a spring 54. The spring 54 always pushes the positioning block 53 downward by its own elasticity, ensuring that the positioning block 53 always contacts the inner wall of the rectangular groove 6 without rotating the guide plate 43, thereby ensuring the stability of positioning. The positioning block 53 is slidably connected to the inner wall of the concave block 52, one end of the spring 54 is fixedly connected to the inner wall of the concave block 52, and the other end of the spring 54 is fixedly connected to the upper surface of the positioning block 53. The outer wall of the guide plate 43 is provided with multiple groups of rectangular grooves 6. The lower surface of the positioning block 53 contacts the inner wall of the rectangular groove 6. The lower surface of the positioning block 53 is an arc surface, which ensures that the positioning block 53 will not jam the guide plate 43, but can position the rectangular groove 6.

[0036] Working principle: when in use, it is only necessary to insert the connecting end of the pipe 1 between the clamping plate 1 41 and the clamping plate 2 45, then the guide plate 43 can be rotated, and the multiple groups of round rods 44 will slide on the inner walls of the arc groove 1 47 and the arc groove 2 48 respectively. At this time, the multiple groups of round rods 44 will drive the clamping plate 1 41 and the clamping plate 2 45 to move along the curvature of the arc groove 1 47 and the arc groove 2 48 respectively, and the clamping plate 1 41 will move toward the outer wall of the pipe 1 and contact it, while the clamping plate 2 45 will move toward the inner wall of the pipe 1 and contact it. At the same time, in the process of rotating the guide plate 43, the positioning block 53 will slide out through its arc surface against the inner wall of the rectangular groove 2 6 and squeeze the spring 54 until the positioning block 53 and the other group of rectangular grooves 2 6 overlaps, at this time, the spring 54 will push the positioning block 53 to move downward and insert into the inner wall of the rectangular groove 2 6 through its own elasticity, and repeatedly support it, which can ensure the accurate positioning of the concave block 52 on the rectangular groove 2 6. After fixing the pipeline 1, it is only necessary to rotate the threaded rod 51. The threaded rod 51 will move downward through its threaded connection with the connecting plate 3, and the lower surface of the threaded rod 51 will rotate in the opposite direction to the concave block 52, and at the same time, it will drive the concave block 52 to move downward, and the concave block 52 will squeeze the spring 54, and the spring 54 will transmit the force to the positioning block 53 through its own elastic characteristics until the concave block 52 is inserted into the inner wall of the rectangular groove 2 6, so that the guide plate 43 can be fixed, which is quick and convenient, and improves work efficiency.

[0037] When it is necessary to dismantle, the threaded rod 51 is reversed to release the fixing of the guide plate 43. At this time, the guide plate 43 is reversed to contact the clamping of the clamping plate 1 41 and the clamping plate 2 45 on the pipe 1, which is quick and convenient and improves work efficiency.

[0038] 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.
