SUMMARY

[0003] The utility model aims at providing a kind of funnel chest correction device with replaceable suction disc structure to solve the problems raised in the above background.

[0004] To achieve the above object, the utility model provides the following technical scheme: a kind of funnel chest correction device with replaceable suction disc structure, including correction suction disc, connecting threaded pipe and connecting device, the connecting threaded pipe is fixedly connected in the upper end middle part of the correction suction disc, the connecting device is arranged on the connecting threaded pipe, the connecting device includes threaded fixed connection pipe, fixed connection pipe, one-way valve and negative pressure extraction pipe, the fixed connection pipe is fixedly connected in the upper end of the threaded fixed connection pipe, the one-way valve is fixedly connected in the outer side end of the fixed connection pipe, the negative pressure extraction pipe is fixedly connected on the one-way valve.

[0005] Preferably, the threaded fixed connection pipe is matched with the connecting threaded pipe.

[0006] Preferably, the bottom end of the connecting threaded pipe is placed with sealing gasket inside, and the bottom end of the threaded fixed connection pipe is extruded contact with the sealing gasket.

[0007] Preferably, the fixed connection pipe is communicated with the inside of the threaded fixed connection pipe, and the threaded fixed connection pipe is communicated with the inside of the connecting threaded pipe.

[0008] Preferably, the upper end middle part of the fixed connection pipe is fixedly installed with screw handle.

[0009] Compared with prior art, the utility model has the beneficial effects as follows:

[0010] When the corrective suction cup needs to be replaced during use, the handle is first turned by external force to rotate the fixed connecting tube and the threaded fixed connecting tube. The rotation of the threaded fixed connecting tube changes the threaded fixed connecting tube and the connecting threaded tube from a threaded fixed state to a threaded movable state. Then, the corrective suction cup can be quickly separated and replaced by turning the corrective suction cup by external force. Therefore, compared with the existing negative pressure extraction tube and corrective suction cup integrated connection device, this device can replace the corrective suction cup more conveniently according to the needs of use. Moreover, when the connecting threaded tube and the threaded fixed connecting tube are threadedly fixed, the sealing gasket set inside plays a sealing role, so that the corrective suction cup can be stably adsorbed for a long time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figs. 1-3 This utility model provides an embodiment of a pectus excavatum correction device with a replaceable suction cup structure, comprising a correction suction cup 1, a connecting threaded tube 2, and a connecting device 3. The connecting threaded tube 2 is fixedly connected to the upper middle part of the correction suction cup 1. The connecting device 3 is disposed on the connecting threaded tube 2. The connecting device 3 includes a threaded fixed connecting tube 5, a fixed connecting tube 7, a one-way valve 8, and a negative pressure extraction tube 9. The fixed connecting tube 7 is fixedly connected to the upper end of the threaded fixed connecting tube 5. The one-way valve 8 is fixedly connected to the outer end of the fixed connecting tube 7. The negative pressure extraction tube 9 is fixedly connected to the one-way valve 8.

[0017] The threaded fixed connecting pipe 5 is compatible with the connecting threaded pipe 2.

[0018] A sealing gasket 4 is placed inside the bottom end of the threaded pipe 2, and the bottom end of the threaded fixed connecting pipe 5 is pressed into contact with the sealing gasket 4 to achieve a sealing effect.

[0019] The fixed connecting pipe 7 is internally connected to the threaded fixed connecting pipe 5, and the threaded fixed connecting pipe 5 is internally connected to the connecting threaded pipe 2. By using the negative pressure extraction pipe 9 to extract gas from the inside of the correction suction cup 1, a vacuum state can be formed, which has sufficient adsorption force.

[0020] A screw-on handle 6 is fixedly installed at the middle of the upper end of the fixed connecting pipe 7. The screw-on handle 6 allows the threaded fixed connecting pipe 5 to be easily rotated and screwed off from the inside of the connecting threaded pipe 2.

[0021] Working principle: When the correction suction cup 1 needs to be replaced during use, first, turn the handle 6 with external force to rotate the fixed connecting tube 7 and the threaded fixed connecting tube 5. The rotation of the threaded fixed connecting tube 5 changes the threaded fixed state between the threaded fixed connecting tube 5 and the connecting threaded tube 2 to the threaded movable state. Then, by turning the correction suction cup 1 with external force, the correction suction cup 1 and the connecting threaded tube 2 and the threaded fixed connecting tube 5 can be quickly separated and replaced. Therefore, compared with the existing integrated connection device of negative pressure extraction tube 9 and correction suction cup 1, this device can replace the correction suction cup 1 more conveniently according to the needs of use. Moreover, when the connecting threaded tube 2 and the threaded fixed connecting tube 5 are threadedly fixed, the sealing gasket 4 set inside plays a sealing role, so that the correction suction cup 1 can stably adsorb for a long time.
