Description

Technical Field

[0001] This invention relates to the field of hyperbaric oxygen chamber technology, and more specifically to a hyperbaric oxygen chamber door track system. Background Technology

[0002] A hyperbaric oxygen chamber is a medical device that creates a high-pressure environment inside while providing pure or high-concentration oxygen to alleviate and treat hypoxic diseases and related conditions. To withstand the high pressure, the chamber is often designed as a cylindrical structure with a circular or elliptical cross-section. The door is located on the curved surface of this cylindrical structure. When the cylindrical structure is not an irregular circle, the curvature of the door's side profile changes. The door needs to ensure stable opening and closing movement and reliable sealing performance. This places higher demands on the design of the door track system. An unreasonable track structure can lead to poor door operation and affect its service life. Traditional door track system designs have certain limitations in this regard.

[0003] Currently, most hyperbaric oxygen chamber doors use straight tracks or simple curved tracks without curvature changes. With such designs, it is difficult to achieve a perfect match between the door's movement trajectory and the complex curved surface of the chamber, and friction or collisions are likely to occur during the opening and closing process. Summary of the Invention

[0004] To address the problems in the prior art, this invention proposes a hyperbaric oxygen chamber door track system.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A hyperbaric oxygen chamber door track system includes two symmetrically arranged track groups. Each track group includes an active track and a driven track. The active track and the driven track are provided with grooves extending along the length direction. Each of the grooves of the active track and the driven track is equipped with a sliding component. All sliding components are fixedly connected to the hyperbaric oxygen chamber door. The planes on which the active track and the driven track are located are perpendicular to the curved surface on which the hyperbaric oxygen chamber door is located. The extension trajectories of the active track and the driven track are variable curvature curves.

[0006] Preferably, the active track is divided into a first track segment and a second track segment along its length, and the driven track is divided into a third track segment and a fourth track segment along its length. The extension trajectories of the first track segment and the third track segment both conform to the guideline shape of the curved surface where the hyperbaric oxygen chamber door is located. When the sliding assembly operates in the first track segment and the third track segment, the door's movement trajectory matches the door's own curved surface, reducing the risk of friction or collision during the opening and closing process.

[0007] Preferably, the second track segment is located at the end of the first track segment near the driven track and extends towards the hyperbaric oxygen chamber door. The combined extension trajectory of the first track segment and the second track segment is a continuous curve with curvature changes not exceeding a predetermined threshold. The gentle turning trajectory can ensure smooth operation of the chamber door and avoid jamming or vibration caused by sudden curvature changes.

[0008] Preferably, the fourth track segment is located at the end of the third track segment away from the active track and extends towards the hyperbaric oxygen chamber door. The combined extension trajectories of the third and fourth track segments form a continuous curve with curvature changes not exceeding a predetermined threshold. When the sliding component operates in the second and fourth track segments, the chamber door tends to move outward a short distance, thereby fitting and sealing against the chamber body. At the same time, the design of the second and fourth track segments also allows the chamber door to maintain a certain distance from the chamber body during opening and closing, avoiding scratches and collisions.

[0009] Preferably, the angle formed by the tangent at the end of the second track segment and the tangent at the junction of the first and second track segments is small, ensuring a smoother change in the drive end trajectory and improving power transmission stability. The angle formed by the tangent at the end of the fourth track segment and the tangent at the junction of the third and fourth track segments is large, avoiding jamming or asynchrony caused by minor track deviations. Here, "larger" / "smaller" refers to a comparison between the two angles.

[0010] Preferably, the sliding component is a pulley, with the pulley rim fitting into the edge of the sliding groove to prevent derailment; the sliding component is fixedly connected to the hyperbaric oxygen chamber door through a track mounting component, so that the chamber door and the track system form a multi-point rigid linkage, improving overall stability.

[0011] Preferably, the active track includes a base plate and a cover plate of the same shape and spaced apart. A drive wheel, multiple driven wheels and a synchronous belt are provided between the base plate and the cover plate. The synchronous belt is wound around the drive wheel and the driven wheels. The drive wheel drives the synchronous belt to run, and the synchronous belt drives the pulley to move in the slide groove, so as to realize the automatic opening and closing of the hatch without manual pushing and pulling.

[0012] Preferably, the synchronous belt is provided with a synchronous belt pressure plate that moves with the synchronous belt. The synchronous belt pressure plate is connected to the pulley assembly and directly transmits the synchronous belt power to the pulley to realize pulley motion control.

[0013] Preferably, the timing belt pressure plate includes an upper pressure plate and a lower pressure plate. The upper pressure plate is provided with a toothed structure that meshes with the timing belt and a connecting end that connects to the rotating shaft of the sliding component. The toothed meshing avoids slippage and enhances the reliability of power transmission.

[0014] Preferably, a timing belt abutment is provided between the base plate and the cover plate, located inside the slide groove. The timing belt passes through the inside of the timing belt abutment. The timing belt abutment is used to limit the lateral displacement of the timing belt and prevent it from detaching from the pulley system or twisting. The timing belt abutment is only provided inside the slide groove to avoid mechanical interference to the pulley.

[0015] This invention achieves a smooth-running variable curvature track through synchronous belt drive design, enabling the hatch trajectory to accurately adapt to the irregular cabin surface, reducing collision losses and maximizing energy utilization; the end of the track achieves a sealing and lifting action while ensuring smooth operation; ultimately, it realizes smooth opening and closing of the hatch, ensuring long-term sealing reliability and extending service life.

Detailed Implementation

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] like Figure 1-4 As shown, a hyperbaric oxygen chamber door track system includes two symmetrically arranged track groups, each consisting of an active track 1 and a driven track 2. Active sliders are mounted on the active track 1, and driven sliders are mounted on the driven track 2, for a total of four sliders. All four sliders are fixedly connected to the hyperbaric oxygen chamber door. The hyperbaric oxygen chamber door is generally arc-shaped, and the planes containing the active track 1 and driven track 2 are perpendicular to the curved surface containing the hyperbaric oxygen chamber door. The curved surface containing the hyperbaric oxygen chamber door is a cylindrical surface, including a circular cylindrical surface, an elliptical cylindrical surface, or a general cylindrical surface. The structure of a single track group is described in detail below.

[0020] like Figure 2 As shown, both the active track 1 and the driven track 2 are curved. The active track 1 includes a longer first track segment 3 and a shorter second track segment 4, while the driven track 2 includes a longer third track segment 5 and a shorter fourth track segment 6. The extended trajectories of the first track segment 3 and the third track segment 5 lie on a curve, and their extended trajectories both conform to the guideline shape of the cylindrical surface where the hyperbaric oxygen chamber door is located. The second track segment 4 is located at the end of the first track segment 3 closest to the driven track 2 and extends towards the hyperbaric oxygen chamber door. The extended trajectories of the first track 3 and the second track segment 4 form a continuous curve, and the curvature change of this curve does not exceed 0.006 mm⁻ 1 The fourth orbit 6 is located at the end of the third orbit 5 furthest from the active orbit 1, extending towards the hyperbaric oxygen chamber door; the extended trajectories of the third orbit 5 and the fourth orbit 6 form a continuous curve with a curvature variation not exceeding 0.03 mm⁻ 1 The ends of the second track segment 4 and the fourth track segment 6 both extend along a straight line. The angle formed by the tangents at the junction of the end of the second track segment 4 and the first and second track segments is set as θ1. The angle formed by the tangents at the junction of the end of the fourth track segment 5 and the third and fourth track segments is set as θ2. θ1 < θ2.

[0021] The active track 1 includes a base plate 101 and a cover plate 102 of the same shape, stacked and spaced apart. The base plate 101 and cover plate 102 have multiple mounting holes 7 for fixing the base plate 101 and cover plate 102 together, and also for installing the active track 1. Both the base plate 101 and cover plate 102 have a sliding groove 8, which extends along the length of the track and continuously passes through the first track section 3 and the second track section 4 of the active track 1. A sliding assembly is provided in the sliding groove 8 of the cover plate 102, and the sliding assembly is connected to the hyperbaric oxygen chamber door via a track mounting component 10. In this embodiment, the sliding assembly is a pulley 9, which is a U-shaped grooved pulley with its rim recessed inward at the center to fit the edge of the sliding groove 8.

[0022] The two sides of the chute 8 are defined as the inner and outer sides. Due to the curved structure of the active track 1, the outer side is longer than the inner side. Multiple synchronous belt guide plates 103 are installed between the inner sides of the base plate 101 and the cover plate 102, arranged end-to-end. Each synchronous belt guide plate 103 includes two symmetrically joined single-sided guide plates, which are respectively fixedly installed on the base plate 101 and the cover plate 102. There is a space between the two single-sided guide plates. Figure 3As shown, a drive wheel 104 and multiple driven wheels 105 are disposed between the base plate 101 and the cover plate 102. The drive wheel 104 is located at the end of the drive track 1 away from the driven track 2. Among the multiple driven wheels 105, one driven wheel 105 is located at the end of the drive track 1 closer to the driven track 2, multiple driven wheels 105 are located at both ends of the synchronous belt abutment 103, and the remaining driven wheels 105 are located between the outer sides of the base plate 101 and the cover plate 102. Both the drive wheel 104 and the driven wheels 105 are mounted on the periphery of the slide groove 8 via pins. The drive wheel 104 is connected to the output end of the motor 106, and the motor 106 is mounted on the cover plate 102.

[0023] A synchronous belt 107 is also provided between the base plate 101 and the cover plate 102. The synchronous belt 107 is wound around the drive wheel 104 and the driven wheel 105, and passes through the synchronous belt abutment 103. Figure 4 As shown, a timing belt pressure plate 108 is provided on the timing belt 107, and the timing belt pressure plate 108 moves synchronously with the operation of the timing belt 107. The pressure plate includes an upper pressure plate and a lower pressure plate, which are connected to the upper pressure plate and are respectively disposed on both sides of the timing belt 107. The end of the upper pressure plate that contacts the timing belt 107 is provided with a toothed structure, which meshes with the timing belt 107. The other end of the upper pressure plate is connected to the shaft of the pulley 9.

[0024] The driven track 2 is also equipped with a groove 8, which extends along the length of the track and continuously passes through the third track section 5 and the fourth track section 6 of the driven track 2. A sliding component, namely a pulley 9, is provided in the groove 8 of the driven track 2. The pulley 9 is connected to the hyperbaric oxygen chamber door via a track mounting component 10. The driven track 2 has multiple mounting holes 7 for installation. The four corners of the hyperbaric oxygen chamber door are connected to four pulleys 9 via the track mounting components 10 of the driving track 1 and the driven track 2. When the pulleys 9 move in the first track section 3 and the third track section 5, the hyperbaric oxygen chamber door moves along the length of the track, opening or closing the door. When the pulleys 9 move to the second track section 4 and the fourth track section 6, the hyperbaric oxygen chamber door closes and then lifts outwards, thus tightly fitting against the hyperbaric oxygen chamber body and achieving a seal.
