Description

Technical Field

[0001] The invention relates to the technical field of oxygen supply tube brackets for breathing masks, in particular to an oxygen supply tube bracket for breathing masks. Background Art

[0002] Oxygen masks are tools worn by people who are hypoxic when they are outdoors. The oxygen supply bracket (also called air supply bracket or oxygen bracket) and the mask body of current oxygen masks are often installed by snap-fitting. The snap joints are fixed at both ends of the oxygen supply bracket, and are snap-fitted and fixed to the two sides of the mask body by the snap joints. Under this installation method, when a single snap joint fails, the entire oxygen supply bracket needs to be replaced, resulting in unnecessary replacement of the oxygen supply bracket and increasing the cost of use. When installing the oxygen supply tube, the oxygen supply bracket usually adopts an interference fit arrangement between the pipeline channel set on the oxygen supply bracket and the oxygen supply tube. This installation method is more troublesome, and when the oxygen mask shakes, the oxygen supply tube is easy to slip in the oxygen supply bracket, affecting the stability of the oxygen supply tube. At the same time, since the oxygen supply bracket and the oxygen supply tube are designed to be independent of each other, the production cost is high, the volume is large after assembly, and the user's comfort is reduced.

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.

[0021] See also Figure 1 The present invention provides a technical solution: an oxygen supply tube support for a breathing mask, comprising an oxygen supply support 1, an oxygen supply channel is arranged in the inner cavity of the oxygen supply support 1, a nasal tube 2 is protruding in the middle of the oxygen supply support 1 and symmetrically arranged, a connecting part 4 is fixedly arranged at both ends of the oxygen supply support 1, a clamping joint 5 is clamped and arranged on the connecting part 4, the oxygen supply tube is interference-fitted and inserted at one end of the connecting part 4 and is connected to the oxygen supply channel, and both ends of the oxygen supply support 1 are clamped and fixed to the two sides of the mask body through the clamping joint 5.

[0022] The present invention, by arranging an oxygen supply channel in the inner cavity of the oxygen supply bracket 1, integrates the functions of the traditional oxygen supply tube and the oxygen supply bracket 1, effectively reduces the occupied space and improves the comfort of personnel in use; at the same time, effectively saves the manufacturing cost, can reduce the cost price, and improve the price advantage of the product; by arranging a card joint 5 that is engaged with the oxygen supply bracket 1, when the card joint 5 is damaged, it is only necessary to independently disassemble and replace the card joint 5 without replacing the oxygen supply bracket 1 as a whole, which effectively saves the actual use cost; the oxygen supply tube is connected to the oxygen supply bracket 1 through the interference fit of the connecting part 4, which can facilitate personnel to quickly connect and use the breathing mask with the oxygen supply bracket 1 in the actual application process.

[0023] Reference Figure 1 As shown, in this embodiment, honeycomb holes 3 are provided on the nasal tube 2. The honeycomb holes 3 arranged on the nasal tube 2 can improve the oxygen output effect, and at the same time can avoid too much insertion of the tube into the nasal cavity, thereby reducing the discomfort caused to the person during the activity.

[0024] In this embodiment, the connecting part 4 includes a limiting shell 41 and an external tube 42 integrally formed with the oxygen supply bracket 1. The oxygen supply bracket 1 is located between the limiting shell 41 and the external tube 42 and is limitedly connected with a card connector 5. A horn groove 43 is provided at one end of the external tube 42 to facilitate quick insertion of the oxygen supply tube.

[0025] Reference Figure 2 and 3 As shown, in this embodiment, the external pipe 42 and the oxygen supply bracket 1 are both made of silicone material. The horn groove 43 is provided to facilitate the rapid insertion of the oxygen supply pipe into the oxygen supply bracket 1; at the same time, since the external pipe 42 is made of silicone material, the sealing performance of the oxygen supply pipe and the external pipe 42 after interference insertion can be ensured.

[0026] Reference Figure 3 As shown, in this embodiment, the clamping joint 5 includes a clamping component 51 and a bending portion 54 fixedly arranged on the clamping component 51. The clamping component 51 is clamped and fixed to the side of the mask body by the bending portion 54. A clamping groove 52 with an open opening is arranged in the middle of the clamping component 51. The clamping component 51 is interference-connected to the outside of the oxygen supply bracket 1 through the clamping groove 52. The clamping component 51 is located between the limiting shell 41 and the external pipe 42. A limiting protrusion 44 is arranged on the oxygen supply bracket 1 at a section between the limiting shell 41 and the external pipe 42. The limiting protrusion 44 is used to limit the clamping component 51 from rotating around the oxygen supply bracket 1. By means of the provided limiting shell 41 and the external tube 42, after the clamping piece 51 is clamped and fixed to the oxygen supply bracket 1, the front-rear displacement of the clamping piece 51 along the oxygen supply bracket 1 can be limited; by means of the provided limiting protrusion 44, the rotation of the clamping piece 51 can be limited, thereby effectively ensuring the stability of the entire clamping piece 5 after being clamped and fixed to the oxygen supply bracket 1, thereby ensuring that the entire oxygen supply bracket 1 is not prone to shaking with the patient's activities after being clamped and fixed to the mask body by the clamping piece 51, thereby improving the patient's comfort in oxygen inhalation using the entire oxygen supply bracket 1.

By setting the weight-reducing groove 53, the weight of the entire clamping joint 5 can be effectively reduced, thereby reducing the weight of the entire oxygen supply bracket 1 after being matched with the clamping joint 5, avoiding the overall weight being too heavy, reducing the burden of personnel when wearing the mask body of the oxygen supply bracket 1 in this solution for oxygen inhalation, and improving the user's comfort; by setting the anti-slip raised strip 55, the stability of the clamping part 51 when being clamped with the mask body in cooperation with the bending part 54 can be improved, so that when the person subsequently wears the mask body for exercise, the clamping joint 5 is not easy to slip on the mask body, thereby improving the stability of the oxygen supply bracket 1 and improving the user's experience: by setting the distinguishing mark 56, it is convenient for personnel to quickly distinguish the left and right clamping parts 51, so as to accurately and quickly clamp the clamping part 51 installed on the oxygen supply bracket 1, and quickly assemble the oxygen supply bracket 1 and the mask body through the clamping part 51 for use.
