Technical Field

[0001] The invention relates to the technical field of air nozzles, in particular to an air nozzle capable of reducing the jamming of elastic beads. Background Art

[0002] When the tire is in use, a tire pressure detection device will be added to the tire as needed. A common method now is to add a connector to the air valve, and then install the tire pressure detection device on the connector, thereby setting the detection device on the air valve.

[0003] A Chinese patent with publication number CN217152510U discloses a telescopic connector, including: an outer shell provided with an accommodating cavity, an elastic element arranged in the accommodating cavity, a first fixed head and a second fixed head installed at both ends of the accommodating cavity, and the outer wall of the outer shell is provided with: a mounting portion and a protruding portion, the protruding portion is close to the first fixed head, the outer diameter of the protruding portion is larger than the outer diameter of the mounting portion, and when the outer shell is installed on the air nozzle, the protruding portion and the mounting portion are riveted into the mounting hole of the air nozzle by riveting, so that the protruding portion clamps the mounting hole.

[0004] Regarding the above technical conditions, there is still a defect that when the connecting piece is installed and riveted, the hole wall of the installation hole squeezes the protrusion, causing the cavity wall of the accommodating cavity to be concave, and the first fixing head is in excessive contact with the cavity wall, causing the first fixing head to be stuck.

[0005] Based on this, the present invention designs a gas nozzle that reduces the possibility of elastic beads getting stuck, so as to solve the above problem. Summary of the invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an air nozzle for reducing the jamming of elastic beads, comprising an elastic bead, a shell for placing the elastic bead, and a body of the air nozzle, wherein the body is provided with a mounting opening, a telescopic spring for resisting the elastic bead is arranged in the shell, a clamping ring is fixedly arranged on the shell, the clamping ring is located in the middle part of the shell, and when the shell is located in the mounting opening, the clamping ring clamps onto the mouth wall of the mounting opening.

[0007] By adopting the above technical solution, during installation, the shell is riveted into the installation opening, and the clamping ring located in the middle is pressed against the installation opening, thereby fixing the shell at the installation opening, squeezing the clamping ring, and the corresponding part of the shell is concave, and the concave part is located between the two elastic beads, thereby reducing the squeezing of the elastic beads and achieving the effect of reducing the elastic beads from getting stuck.

[0008] Preferably, a guiding slope is provided on the clamping ring.

[0009] By adopting the above technical solution, when inserting into the installation opening, the guiding inclined surface guides the clamping ring, so that the clamping ring is convenient to enter into the installation opening.

[0010] Preferably, a force-releasing surface is provided on the clamping ring.

[0011] By adopting the above technical solution, a force relief surface is left during riveting, which can reduce the impact force on the rest of the shell to form deformation, and concentrate the deformed part of the shell on the clamping ring, thereby achieving the effect of further reducing the elastic bead from getting stuck.

[0012] Preferably, one end of the housing provided with the elastic bead is provided with a mounting ring, the mounting ring is designed to be bowl-shaped with an opening in the middle, and the elastic bead is located in the mounting ring.

[0013] By adopting the above technical solution, when installing the shell, the installation ring can guide the shell to be inserted into the installation opening, so that the installation of the shell is convenient.

[0014] In summary, the present application has the following beneficial technical effects: during installation, the outer shell is riveted into the installation opening, at which time the clamping ring located in the middle presses against the installation opening, thereby fixing the outer shell at the installation opening, squeezing the clamping ring, and causing the corresponding part of the outer shell to be concave, and the concave part is located between the two elastic beads, thereby reducing the squeezing of the elastic beads and achieving the effect of reducing the elastic beads from getting stuck.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] Reference Figure 1-Figure 6 , an air nozzle for reducing the stuck state of an elastic bead, comprising an elastic bead 1, a shell 2 for placing the elastic bead 1, and a body 3 of the air nozzle, a mounting block 4 is fixedly arranged on the body 3, and a mounting opening 5 is opened on the mounting block 4; a telescopic spring 6 for resisting the elastic bead 1 is arranged in the shell 2, two elastic beads 1 are arranged, and the telescopic spring 6 is located between the two elastic beads 1, a fixing ring 7 is fixedly arranged at one end of the shell 2, and a mounting ring 8 is fixedly arranged at the other end, and the mounting ring 8 is designed in a bowl shape with an opening in the middle, one elastic bead 1 is located in the fixing ring 7, and the other elastic bead 1 is located in the mounting ring 8;

[0027] Reference Figure 1-Figure 6 A clamping ring 9 is fixedly provided on the shell 2, and the clamping ring 9 and the shell 2 are formed together. A guiding inclined surface 10 is provided on the clamping ring 9, and the clamping ring 9 is located in the middle of the shell 2; when the shell 2 is installed, the shell 2 is inserted into the installation port 5, and the shell 2 is pressed into the installation port 5 by riveting equipment; when the riveting is completed, the two elastic beads 1 are respectively located outside the installation port 5, and the clamping ring 9 located in the middle is pressed against the installation port 5, so that the shell 2 is fixed in the installation port 5. When entering the installation port 5, the wall of the installation port 5 squeezes the clamping ring 9, and the corresponding part of the shell 2 is concave, and the concave part is located between the two elastic beads 1, thereby reducing the squeezing of the elastic beads 1, thereby achieving the effect of reducing the elastic beads 1 from getting stuck.

[0028] Reference Figure 1-Figure 6 A force-releasing surface 11 is provided on the clamping ring 9. During riveting, the force-releasing surface 11 is left. The force-releasing surface 11 is an inwardly concave inclined surface, which can reduce the impact force on the rest of the shell 2 to form deformation, and make the deformation of the shell 2 concentrated on the area near the clamping ring 9, so as to further reduce the effect of the elastic bead 1 getting stuck.

[0029] Reference Figure 1-Figure 6When installing the shell 2 , the bowl-shaped design of the mounting ring 8 can guide the shell 2 to be inserted into the mounting opening 5 , making it convenient to install the shell 2 ; when inserting into the mounting opening 5 , the guiding inclined surface 10 guides the snap ring 9 , making it convenient for the snap ring 9 to enter the mounting opening 5 .

[0030] The implementation principle of this embodiment is: when installing the shell 2, the shell 2 is placed on the installation opening 5 and riveted by riveting equipment. During riveting, the clamping ring 9 is squeezed and deformed to enter the installation opening 5. At this time, the force unloading surface 11 guides the impact force to concentrate the deformation caused by the pressure on the nearby area; after the shell 2 is completely entered, the clamping ring 9 is pressed against the installation opening 5, and the corresponding part of the shell 2 is concave, and the concave part is located between the two elastic beads 1, thereby reducing the squeezing of the elastic beads 1 and achieving the effect of reducing the elastic beads 1 from getting stuck.
