Description

Technical Field

[0001] This utility model relates to the field of medical equipment support structures, specifically to a connecting piece device structure for an external support frame of a soft oxygen chamber. Background Technology

[0002] In recent years, soft oxygen chambers have been widely used in home and medical institutions for assisted respiratory therapy due to their portability and good airtightness. However, in order to ensure the stability of the chamber and withstand the pressure difference between the inside and outside, it is usually necessary to install a metal or engineering plastic support frame on the outside of the chamber.

[0003] Existing technologies for bracket connections mostly employ riveting, welding, or one-piece molding, resulting in bulky, inconvenient-to-transport structures that also lack adjustable connection lengths. Modular assembly structures using bolts and nuts have become the mainstream trend in the industry. While some solutions utilize bolts and nuts for modular splicing, these connections rely on friction fit and lack limiting design. Over long-term use, external forces can cause the nuts to loosen, leading to bracket instability or even disintegration, posing significant safety hazards.

[0004] Therefore, there is an urgent need to design a connecting piece device structure for the external support of a soft oxygen chamber to meet the connection and use requirements of the current modular structure of the external support of a soft oxygen chamber. Utility Model Content

[0005] The purpose of this utility model is to provide a connecting piece device structure for the external support of a soft oxygen chamber. This connecting piece device structure can realize the modular and rapid assembly of the support, the adjustment of the support length, and the reliable anti-loosening and locking of the fasteners.

[0006] The technical solution adopted by this utility model to solve the above problems is: a connecting piece device structure for an external support of a soft oxygen chamber, including a frame and several connecting seats. The frame includes several sets of connecting segments connected end to end by the connecting seats. The ends of two adjacent sets of connecting segments are set in the connecting seats and fixed to the two ends of the connecting seats by two sets of bolts and nuts respectively. Several sets of bolt and nut mounting positions are provided on the connecting seats.

[0007] Preferably, the connecting seat includes two sets of connecting members, and the mounting position is provided in no less than two sets, each including a plurality of mounting holes arranged in pairs on the two sets of connecting members, the mounting holes being used for bolts to pass through.

[0008] Preferably, the two sets of connectors are slidably connected, and each of the connectors has a guide groove and a guide bar on both sides that are slidably connected and adapted to each other.

[0009] Preferably, the connector is also fitted with two sets of elastic limiting members to prevent the nut from loosening.

[0010] Preferably, the limiting member is symmetrically provided with two sets of elastic arms, which open outwards. The connecting member is symmetrically provided with two sets of folded edges, which are provided with V-shaped grooves. The two ends of the grooves are respectively slidably adapted to the elastic arms of the two sets of limiting members. The limiting member is clamped between the two sets of grooves, and one side of the elastic arm is in contact with the end of the nut.

[0011] Preferably, a through groove is provided between the two sets of elastic arms to avoid the bolt.

[0012] Preferably, the limiting component is provided with a paddle, and the paddle has a long strip-shaped anti-slip texture.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This invention achieves modular, rapid assembly and length adjustment of the soft oxygen chamber support frame by incorporating two sets of slidable connecting parts within the connecting seat, along with multiple equidistant installation positions, thus enhancing on-site adaptability and assembly capabilities. The sliding fit structure of guide grooves and guide bars between the connecting parts ensures excellent fit accuracy and resistance to external forces after assembly. The V-shaped inclined groove design, combined with elastic limiting components, creates a stable frictional locking force between the elastic arm and the nut end face when the nut is tightened, effectively preventing nut loosening during use. Through grooves between the elastic limiting components ensure unobstructed bolt passage, and the limiting components are equipped with anti-slip tabs for quick manual disassembly and assembly, simplifying maintenance and improving ease of use.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example:

[0022] See Figures 1-4 In this embodiment, a connecting piece device structure for an external support frame of a soft oxygen chamber is disclosed. Specifically, it is used to support and fix the outer shell of the soft oxygen chamber, ensuring modular assembly of the support frame when the chamber is subjected to internal pressurization or external tension. Specifically, it includes a frame body 11 and several connecting seats 12. The frame body 11 includes several sets of connecting segments 13 connected end to end by the connecting seats 12. The ends of two adjacent sets of connecting segments 13 are disposed in the connecting seats 12 and are respectively fixed to the two ends of the connecting seats 12 by two sets of bolts 14 and nuts 15. Several sets of mounting positions 16 for bolts 14 and nuts 15 are provided on the connecting seats 12.

[0023] Specifically, in this embodiment, the assembly and fitting of the support is as follows: First, take two sets of adjacent required connecting segments 13. The ends of the connecting segments 13 are provided with through holes. Insert the two sets of connecting segments 13 along the length direction of the connecting seat 12, so that the through holes of the connecting segments 13 are aligned with the mounting positions 16. Insert the bolts 14 from one side of the mounting positions 16 of the connecting seat 12, pass through the through holes of the connecting segments 13, and extend out from the other side of the mounting positions 16. Then, tighten the nuts 15 to achieve the docking and fixing of the two sets of connecting segments 13. The connection method with the connecting segments 13 is the same as above. In this embodiment, multiple sets of mounting positions 16 are provided along the length direction of the connecting seat 12. Therefore, the through holes at the ends of the connecting segments 13 can be fixed on mounting seats at different positions as needed. The user can fix the two sets of connecting segments 13 on two mounting positions 16 with the same spacing according to the required support width, so as to realize the adjustment of the overall telescopic length of the support. It can be adaptively adjusted according to the support length required by different specifications of soft oxygen chambers used on site.

[0024] The connecting seat 12 includes two sets of connecting members 17, and the mounting positions 16 are provided in at least two sets, each including a plurality of mounting holes 18 arranged in pairs on the two sets of connecting members 17. The mounting holes 18 are for bolts 14 to pass through. The mounting holes 18 can be elongated holes, so that the mounting holes 18 have an adjustment margin. On the one hand, this allows for fine adjustment of the overall length of the bracket, and on the other hand, it facilitates the bolts 14 to be inserted through the mounting holes 18 and the through holes of the connecting section 13 without precise alignment, thus facilitating the overall assembly of the bracket.

[0025] See Figure 3The two sets of connectors 17 are slidably connected. Each connector 17 has a guide groove 21 and a guide strip 22 on its two sides, which are mutually slidably adapted to each other. Specifically, each connector 17 has a raised edge 23 on its side, the guide groove 21 is located inside the raised edge 23, and the raised strip is located on the opposite side of the raised edge 23. The connector 17 adopts a U-shaped cross-section structure, and the two sets of connectors 17, when assembled, form a rectangular cross-section that matches the cross-section of the bracket. During installation, the two sets of connectors 17 are staggered, and the ends of their respective raised strips are aligned with the ends of the raised edges 23, so that the raised strips slide into the guide grooves 21 until the ends of the two sets of connectors 17 are flush. At this time, since the two sets of connectors 17 are connected by sliding along their length, external force cannot separate the guide groove 21 and the guide bar 22 along the direction perpendicular to their length. The two sets of connectors 17 are spliced ​​together, so that the ends of the two sets of connecting segments 13 are firmly clamped between the two sets of connectors 17, so that the connecting segments 13 can slide into them (between the two sets of connectors 17) for limiting and restricting their swing, which facilitates the subsequent installation and fixing of bolts 14 and nuts 15.

[0026] See Figure 4 The connector 17 is also connected to two sets of elastic limiting members 24 to prevent the nut 15 from loosening. The limiting members 24 are detachably connected to the connector 17. Specifically, the limiting members 24 are symmetrically provided with two sets of elastic arms 25, which open outwards. The connector 17 is symmetrically provided with two sets of folded edges 26, each with a V-shaped groove 27. The two ends of the groove 27 are slidably adapted to the elastic arms 25 of the two sets of limiting members 24. After the limiting member 24 slides into the groove 27, its two elastic arms 25 slide and deform against the side wall of the groove 27, while its part fits against the end face of the tightened nut 15, effectively preventing the nut 15 from loosening. The deepest depth of the groove 27 is no greater than the outward opening length of the elastic arm 25 when it is not under force. The inward squeezing force of the groove 27 on the elastic arm 25 prevents the limiting members 24 from loosening. Similarly, in this embodiment, the connector 17 is also connected to a limiting member 24 on the nut side of the bolt 14. The limiting member 24 contacts the nut of the bolt 14 to prevent the bolt 14 from loosening.

[0027] A through groove 28, matching the outer diameter of the bolt 14, is provided between the two sets of elastic arms 25. The through groove 28 is arranged along the center line of the limiting member 24 and has a U-shaped structure. After the two sets of elastic arms 25 are inserted into the inclined groove 27, the width of the through groove 28 should be greater than the radial dimension of the bolt 14, so that the bolt 14 can pass through the through groove 28, avoiding the limitation of the installation depth of the limiting member 24 and ensuring that the limiting member 24 can be inserted between the two sets of folded edges 26 of the connector 17. The limiting member 24 is provided with a lever 29, which has a long strip-shaped anti-slip texture. By pushing the lever 29 outward with a finger, the two sets of elastic arms 25 can be disengaged from the inclined groove 27, and the limiting member 24 can be removed to expose the nut 15 for easy disassembly of the connector 17.

[0028] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
