Description

Connecting sheet device structure of soft oxygen cabin outer support Technical Field The utility model relates to the field of medical equipment supporting structures, in particular to a connecting sheet device structure of a soft oxygen cabin outer bracket. Background In recent years, soft oxygen chambers have been widely used for assisted respiratory therapy in homes and medical institutions due to their portability and good tightness. However, in order to ensure the stability of the cabin and bear the difference between the internal and external air pressure, a metal or engineering plastic bracket is usually arranged on the outer side of the cabin. The support connection in the prior art adopts riveting, welding or one-step forming die forming parts, and the integral structure is large in size and inconvenient to transport, and meanwhile, the connection length of the support cannot be adjusted. The modular assembly structure of the bracket is realized by means of bolts, nuts and the like, and the modular assembly structure becomes a mainstream trend of the current industry. The proposal of modular splicing of bolts and nuts is also adopted, but the connection depends on friction fit, lacks limit design, is easy to loosen due to external force in long-term use, causes instability and even disassembly of the bracket, and has great potential safety hazard. Therefore, there is a need to design a connecting piece device structure of the external soft oxygen cabin bracket, which meets the connection use requirement of the modularized structure of the external soft oxygen cabin bracket at present. Disclosure of utility model The utility model aims to provide a connecting piece device structure of a soft oxygen cabin outer bracket, which can realize modularized rapid assembly of the bracket, adjustment of supporting length and reliable anti-loosening locking of a fastener. The utility model solves the problems by adopting the technical scheme that the connecting piece device structure of the soft oxygen cabin outer bracket comprises a bracket body and a plurality of connecting seats, wherein the bracket body comprises a plurality of groups of connecting sections which are sequentially connected end to end through the connecting seats, the end parts of two adjacent groups of connecting sections are arranged in the connecting seats and are respectively fixed at the two ends of the connecting seats through two groups of bolts and nuts, and the connecting seats are provided with mounting positions of the plurality of groups of bolts and nuts. Preferably, the connecting seat comprises two groups of connecting pieces, the installation positions are not less than two groups, the connecting seat comprises a plurality of installation holes which are respectively formed in the two groups of connecting pieces in pairs, and the installation holes are used for bolts to pass through. Preferably, the two groups of connecting pieces are connected in a sliding way, and guide grooves and guide bars which are matched in a sliding way are respectively arranged on two sides of the connecting pieces. Preferably, the connecting piece is also connected and matched with two groups of elastic limiting pieces for preventing the nut from loosening. Preferably, the limiting piece is symmetrically provided with two groups of elastic arms, the two groups of elastic arms are outwards opened, the connecting piece is symmetrically provided with two groups of folded edges, the folded edges are provided with V-shaped inclined grooves, two ends of each inclined groove are respectively in sliding fit with the elastic arms of the two groups of limiting pieces, the limiting piece is clamped between the two groups of inclined grooves, and one side of each elastic arm is attached to the end part of the nut. Preferably, through grooves for avoiding bolts are formed between the two groups of elastic arms. Preferably, the limiting piece is provided with a poking piece, and the poking piece is provided with strip-shaped anti-skid textures. Compared with the prior art, the utility model has the following advantages and effects: According to the utility model, through arranging two groups of connecting pieces capable of being assembled in a sliding manner in the connecting seat and matching with a plurality of groups of equidistant mounting positions, the modularized rapid assembly and the length adjustment of the soft oxygen cabin bracket are realized, and the on-site adaptive assembly capacity is improved. Through the guide slot and the guide bar sliding fit structure between the connecting pieces, the assembled structure is ensured to have good fit precision and external force resistance. The V-shaped chute is matched with the elastic limiting piece, and stable friction locking force is formed between the elastic arm and the end face of the nut when the nut is locked, so that the nut of the bracket is effectively prevented from loosening in the use process
