Description

Technical Field

[0001] This utility model relates to the field of life support equipment technology, and in particular to an anti-detachment structure for the connecting pipe of an oxygen generator. Background Technology

[0002] As a life support device carried by individual soldiers, the individual oxygen concentrator is characterized by its small size and light weight, providing continuous oxygen supply to combat personnel in oxygen-deficient or confined environments such as high altitudes and tunnels. Unlike home oxygen concentrators used in fixed locations, individual oxygen concentrators need to be directly installed on the personnel and move with them during tactical maneuvers. During this process, personnel need to perform intense and varied tactical movements such as running, jumping, crawling, and even tactical prone positions. This causes the connection between the gas pipeline and the main body of the oxygen concentrator to be frequently subjected to tensile, torsional, and impact loads. Currently, common connection methods include... Figure 1 As shown, the current method primarily involves directly attaching a hose to the outer wall of the oxygen concentrator's nozzle, relying on static friction between the hose material and the nozzle's outer wall to maintain the connection. This method has limited connection strength; under repeated stress, vibration, or accidental snagging, the hose is highly susceptible to detaching from the nozzle, leading not only to oxygen supply interruptions and endangering personnel safety but also affecting the execution of combat missions. Therefore, while maintaining the existing socket-type connection method, it is urgently necessary to design a reinforced structure that can effectively resist detachment, significantly improving the reliability and strength of the connection and preventing accidental oxygen supply interruptions due to connection failure. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-detachment structure for the connecting pipe of an oxygen generator, so as to solve the technical problems of poor reliability of the pipe connection of individual oxygen generators in the prior art, which is easy to fall off due to pulling.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: An anti-detachment structure for an oxygen generator connecting pipe includes a flexible sleeve, which is elastic and used to be fitted onto the pipe and fastened to it by friction. A clamp having an opening for snapping and holding onto the connection between the pipe and the nozzle; and a connector connecting the clamp and the sleeve. The length of the connector is configured such that when the sleeve, clamp, and connector are assembled on the pipe, the pipe section between the clamp and the sleeve is bent to form a tension buffer.

[0005] Preferably, the connector is a flexible rod.

[0006] Preferably, the connector is a spring rope.

[0007] Preferably, the clamp is an integral structure, including a first clamp piece for abutting one side of the connection between the pipe and the nozzle; Two second clips extend from both ends of the first clip and form a V-shaped angle with the first clip; Two third clips are respectively connected to the ends of the two second clips away from the first clips, and the inner wall of the third clips is formed to fit the outer wall of the pipe. The opening of the clamp is defined between the two third clamp pieces.

[0008] Preferably, the clamp further includes two fourth clamping pieces, which are folded outward from the ends of the two third clamping pieces away from the second clamping pieces, and are used as force-applying parts to pry open the opening.

[0009] Preferably, the first clip is provided with a first connecting portion for connecting the connector.

[0010] Preferably, the soft sleeve is provided with a second connecting part for connecting the connector.

[0011] Preferably, each of the two third clips has an opening.

[0012] Preferably, the outer wall of the soft sleeve is symmetrically provided with protrusions on both sides, and the size and position of the protrusions are adapted to the opening; in the stored state, the soft sleeve can be accommodated between two third clips and fixed by the snap-fit ​​of the protrusions and the opening.

[0013] The beneficial effects of this utility model are: 1. This utility model, by setting up a tensile buffer structure composed of clamps, soft sleeves, connectors and curved pipes, effectively buffers and transfers the tensile force acting on the far end of the pipe, avoiding the tensile force from acting directly on the fragile connection interface, thereby significantly improving the pull-out resistance and reliability of the connection.

[0014] 2. This utility model does not require any changes to the existing oxygen generator nozzle and pipeline design. It can be directly installed and used as an additional enhancement module. The installation process only requires inserting the clamp and putting on the soft sleeve. The operation is intuitive and quick, and it has good compatibility and versatility.

[0015] 3. This utility model, through the ingenious matching structure on the clamp and the soft sleeve, allows the soft sleeve to be easily fixed on the clamp when not in use, realizing integrated storage of components, preventing the loss of small parts, and making it convenient for users to carry and manage.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] Example 1 Please see Figures 1-3 This embodiment provides an anti-detachment structure for the connecting pipe of an oxygen generator to strengthen the connection between the pipe and the nozzle. The structure includes a soft sleeve 1, a connector, and a clamp 3.

[0021] Please refer to 2. The soft sleeve 1 is made of an elastic material with a high coefficient of friction (such as silicone, rubber, etc.). Its inner diameter is slightly smaller than the outer diameter of the pipe. When in use, it can be tightly fitted onto the pipe and achieve its own stable fixation on the pipe through the friction generated by the interference fit.

[0022] The clamp 3 is preferably integrally injection molded from an engineering plastic (such as ABS, PC, etc.) with a certain strength and elasticity. Figure 2 and Figure 3 As shown, the clamp 3 has an ingenious overall structure, including a first clamping piece 31, two second clamping pieces 32, two third clamping pieces 33, and two fourth clamping pieces 34.

[0023] Please see Figure 3 The first clamp 31 serves as the base, abutting against the outer periphery of the connection between the pipe and the nozzle during use. Two second clamps 32 extend integrally from both ends of the first clamp 31, forming an approximate V- or U-shaped angle with it, together constituting a base for accommodating the pipe. Two third clamps 33 are connected to the free ends of the two second clamps 32, their inner walls designed as arc surfaces adapted to the outer wall of the pipe for clamping. An opening naturally forms between the ends of the two third clamps 33, allowing the clamp 3 to be easily snapped onto the pipe from the side. For ease of installation and removal, the clamp 3 also includes two fourth clamps 34, which extend outward from the free ends of the third clamps 33, forming a force-applying part that facilitates finger application. When the clamp 3 needs to be removed, the user can pry the two fourth clamps 34 outward, widening the opening between the third clamps 33, thus easily removing the clamp 3 from the pipe.

[0024] In this embodiment, the connector is a flexible rod 2, one end of which is fixedly connected to the clamp 3, and the other end is fixedly connected to the soft sleeve 1.

[0025] The installation and working principle of this embodiment are as follows: Figure 2 As shown, firstly, the end of the pipe is connected to the nozzle of the oxygen concentrator. Then, clamp 3 is inserted from its opening, with its third clamp 33 holding the connection area between the pipe and the nozzle, and the first clamp 31 abutting against the end face of the connection. Next, the flexible sleeve 1 is placed on the pipe at a certain distance from clamp 3. Since the length of the flexible rod 2 is preset and less than the straight-line distance between clamp 3 and flexible sleeve 1 in their naturally straightened state on the pipe, when the flexible rod 2 is connected to clamp 3 and flexible sleeve 1, it will force the section of pipe between clamp 3 and flexible sleeve 1 to bend, forming an Ω-shaped or U-shaped tension buffer.

[0026] When the distal end of the tubing (not shown, typically connected to the breathing mask) is accidentally pulled, the tension is transmitted along the tubing to the flexible sleeve 1. Since the flexible sleeve 1 is connected to the clamp 3, which is securely fixed at the connection point, via the flexible rod 2, the tension primarily acts on the flexible rod 2 and the bent section of tubing. The effect of the tension is to attempt to straighten this bent section of tubing, rather than acting directly on the frictional connection interface between the tubing and the nozzle. This "straightening" process greatly absorbs and dissipates the tension energy, providing an effective buffer and protecting the connection point at the front end, preventing the tubing from being pulled directly from the nozzle.

[0027] Example 2 Please see Figure 4 and Figure 5This embodiment is basically the same as Embodiment 1, the main difference being the type of connector. In this embodiment, the connector is an elastic spring rope 4. Both ends of the spring rope 4 are connected to the clamp 3 and the soft sleeve 1, respectively.

[0028] Compared to the flexible rod 2, the spring rope 4 provides a connection while also having tensile elasticity. When the pipe is pulled, in addition to the curved pipe section being straightened to provide cushioning, the spring rope 4 itself is also stretched, providing additional cushioning and elastic recovery capabilities, further enhancing the anti-detachment effect.

[0029] Example 3 Please see Figure 6 Based on Embodiment 1 or Embodiment 2, this embodiment adds a clever storage function design. Specifically, an opening is provided on the arc wall of each of the two third clips 33 of the clamp 3. Correspondingly, two protrusions 5 are symmetrically provided on both sides of the outer wall of the soft sleeve 1. The shape, size and position of these two protrusions 5 are precisely matched with the openings on the third clips 33.

[0030] When not using this anti-detachment structure, in order to facilitate storage and prevent the loss of small parts, the user can place the soft sleeve 1 between the two third clips 33 of the clamp 3 and then press it gently so that the two protrusions 5 on the soft sleeve 1 can be inserted into the openings on the third clips 33. Through this snap-fit, the soft sleeve 1 is firmly fixed on the clamp 3. The two parts are integrated into one, which is convenient for overall storage and carrying.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
