DETAILED DESCRIPTION

[0028] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0030] See also Figures 1 to 5As shown, the utility model proposes a suction cup type traction device to solve the problems of easy leakage and insufficient adsorption when adsorbing complex human body shapes and smaller parts without corresponding instruments and universal suction cups. Specifically, the suction cup type traction device 100 includes a base 10, a negative pressure tube 20 and a suction cup assembly 30. A first chamber 101 is formed in the base 10. One end of the negative pressure tube 20 is connected to the first chamber 101, and the other end is connected to a negative pressure mechanism. The suction cup assembly 30 is installed on the base 10. The negative pressure mechanism drives the first chamber 101 to be in a negative pressure state, so that the suction cup assembly 30 generates suction to pull the object to be pulled.

[0031] See also Figures 1 to 5 As shown, in this embodiment, the suction cup assembly 30 includes a connecting member 31 and at least one suction cup structure 32, the connecting member 31 is connected to the base 10, the suction cup structure 32 is installed on the connecting member 31, the suction cup structure 32 is attached to the surface of the body to be towed to form a second chamber, the second chamber is connected to the first chamber 101, the negative pressure mechanism drives the first chamber 101 and the second chamber to be in a negative pressure state, so that the suction cup structure 32 can be tightly adsorbed on the surface of the body to be towed, thereby achieving traction.

[0032] See also Figures 1 to 4 As shown, in a specific embodiment, the connecting member 31 includes a first connecting member 311 and a second connecting member 312, the first connecting member 311 is provided with a plurality of airflow channels 301, the airflow channels 301 are communicated with the first chamber 101, the second connecting member 312 is wrapped around the outside of the first connecting member 311, and is fixedly connected to the base 10 to fix and install the first connecting member 311. Specifically, in this embodiment, a threaded structure is provided on the outer circumferential surface of the base 10, and a thread matching the threaded structure on the base 10 is provided on the inner surface of the second connecting member 312, and the second connecting member 312 is threadedly connected to the base 10 through the above-mentioned threaded structure to achieve fixation.

[0033] See also Figures 1 to 4As shown, in the present embodiment, a limiting plate 3121 is formed in the radial direction at one end of the second connecting member 312 away from the base 10, and a side of the first connecting member 311 away from the base 10 abuts against the limiting plate 3121, and the other side contacts the base 10. It can be understood that the inner diameter of the end of the second connecting member 312 away from the base 10 is smaller than the inner diameter of the first connecting member 311, so that when installing, the first connecting member 311 is installed inside the second connecting member 312, and when the second connecting member 312 is connected to the base 10, the first connecting member 311 can be fixed inside it. When disassembling, it is only necessary to remove the second connecting member 312 from the base 10 to disassemble the first connecting member 311. It has a simple structure and is easy to install and disassemble.

[0034] See also Figures 1 to 4 As shown, in this embodiment, a hollow conical boss 401 and a first groove 402 are provided on one side of the base 10 and the first connecting member 311 where the base 10 and the first connecting member 311 contact each other, and the conical boss 401 and the first groove 402 correspond to the airflow channel 301 one by one, respectively. When the first connecting member 311 is connected to the base 10, the conical boss 401 and the first groove 402 are both connected to the airflow channel 301 and the first chamber 101, and the conical boss 401 is located in the first groove 402, and an interference fit is formed to achieve fixation.

[0035] See also Figures 1 to 4 As shown, in this embodiment, the suction cup structure 32 includes a suction cup 321 and a pipeline 322, one end of the pipeline 322 is located in the air flow channel 301 and is fixed by the cooperation of the conical boss 401 and the first groove 402, and the other end is installed with the suction cup 322 and is connected to the second chamber formed by the suction cup 322 being attached to the surface of the to-be-towed part, and the pipeline 322 is provided in at least part of the air flow channel 301, that is, the number of suction cups 321 can be set as needed, and multiple suction cups 321 or suction cups 321 with larger areas can be set for parts with larger traction surfaces, and fewer suction cups 321 or suction cups 321 with smaller areas can be set for parts with smaller traction surfaces, so that it has strong adaptability in practical applications and can fit most parts of the human body, that is, a pipeline of appropriate length and a suction cup of appropriate size can be selected according to practical application needs. It should be noted that when installing the pipeline 322, the airflow channel 301 where the pipeline 322 is not installed needs to be sealed, for example, by a pipe plug, to avoid air leakage, thereby ensuring that it can normally achieve negative pressure conditions. In this embodiment, the pipeline 322 is preferably a hose, which provides a certain degree of freedom during traction, so as to facilitate the fixation and traction of the suction cup 321 and the object to be traction. The suction cup 321 is made of soft material and can fit well with the surface of the human body.

[0036] It is understandable that in actual work, sealing structures can be added as needed between various components, such as between the first connecting member 311 and the second connecting member 312, between the first connecting member 311, the second connecting member 312 and the base 10, and between the suction cup structure 32 and the connecting member 31, so as to enhance the overall air tightness and ensure the accuracy of the negative pressure working condition.

[0037] See also Figures 1 to 4 As shown, in this embodiment, the hollow conical boss 401 can be arranged on the side where the first connecting member 311 contacts the base 10, and corresponds to one of the airflow channels 301 respectively. The first groove 402 can be arranged on the side where the base 10 contacts the first connecting member 311. The pipeline 322 is located at one end of the airflow channel 301 and extends into the conical boss 401. When the first connecting member 311 is connected to the base 10, the conical boss 401 is inserted into the first groove 402. The conical boss 401 is squeezed by the first groove 402 and contracts radially inward, thereby fixing the pipeline 322 in the airflow channel 301. Of course, in some other embodiments, an elastic member may be further provided inside one end of the pipeline 322 located inside the conical boss 401 to apply a pressure from the inside to the outside to the pipeline 322, and cooperate with the force applied by the inward contraction of the conical boss 401 to further improve the reliability of the fixation of the pipeline 322. It is understandable that the elastic member cannot block the pipeline 322 to ensure the smooth flow of the pipeline 322.

[0038] See also Figures 1 to 4 As shown, in actual operation, the hose of the suction cup structure 32 is passed through the air flow channel 301 on the first connecting member 311, and the hose is adjusted to a suitable length according to actual needs. The first connecting member 311 and the base 10 are pre-installed, and then the second connecting member 312 is fixedly connected to the base 10. The conical boss 401 is squeezed by the first groove 402 and contracts radially inward to generate an axial force that can fix the hose. According to the actual situation of the adsorbed surface, a suitable negative pressure condition is selected to perform negative pressure operation, so that the traction function of the human body can be realized.

[0039] Of course, in some other embodiments, the hollow conical boss 401 can be arranged on the surface of the base 10 that contacts the first connecting member 311, and the hollow pipe in the conical boss 401 is connected to the first chamber 101, and the first grooves 402 can be arranged on the surface of the first connecting member 311 that contacts the base 10, and respectively correspond to one of the airflow channels 301, and the pipe 322 is located at one end of the airflow channel 301 and extends into the first groove 402. When the first connecting member 311 is connected to the base 10, the conical boss 401 is inserted into the first groove 402, and the pipe 322 is located between the outer wall of the conical boss 401 and the inner wall of the first groove 402, and the pipe 322 is fixed by the extrusion effect between the conical boss 401 and the first groove 402.

[0040] See also Figures 1 to 4 As shown, in the present embodiment, the first connecting member 311 and the base 10 are respectively provided with corresponding second grooves 403 on the sides close to each other, and a spring is installed in the second groove 403. When the second connecting member 312 is connected to the base 10, the spring is in a compressed state. When the second connecting member 312 is removed, the first connecting member 311 and the base 10 can be easily disassembled with the assistance of the elastic force of the spring, and the length of the pipeline 322 can be changed as needed.

[0041] See also Figure 5 As shown, in another embodiment, the connecting member 31 can also be configured as a bellows, one end of which is fixedly connected to the base 10, and the end face of the other end is fitted to the surface of the body to be towed. In this embodiment, the bellows can be extended and retracted along its axial direction. It can be understood that the extension degree of each part of the circumference of the bellows can be different, for example, one side is extended and the other side is contracted, so that the bellows bends toward the contracted side, that is, the bellows can produce axial compression deformation and circumferential bending deformation. The material used for the bellows should be able to produce an appropriate amount of deformation, and the two ends of the bellows should be able to fit tightly with the base 10 and the suction cup respectively, and the bellows-shaped shell has a certain amount of compression. When the device is subjected to negative pressure operation, the bellows-shaped structure can further increase the pressure generated, which can be suitable for complex limb shapes, thereby making the adsorption capacity stronger.

[0042] It is understandable that in actual work, a sealing structure may be added between various components, such as the bellows and the base 10, as needed to enhance the overall air tightness and ensure the accuracy of the negative pressure working condition.

[0043] See also Figure 5As shown, in this embodiment, the suction cup structure 32 is an annular suction cup, which is arranged around one end of the bellows that is attached to the surface of the object to be towed, and the annular suction cup includes a fixed side 323 and a free side 324, the fixed side 323 is fixedly connected to the bellows, and the profile of the free side 324 is formed by a plurality of concave arcs and convex arcs arranged at intervals, and attached to the surface of the object to be towed. It can be understood that when the traction mechanism is adsorbed, the end annular contact surface of the bellows first adheres to the surface of the object to be towed to form a first layer of sealing. When there is air leakage, the negative pressure will cause the free side 324 of the annular suction cup to be further adsorbed on the surface of the object to be towed, so as to achieve a double-layer seal and enhance the air tightness.

[0044] See also Figure 5 As shown, in actual operation, the traction mechanism should be placed on the target surface first, and then the bottom edge of the bellows should be preliminarily fitted with the target surface, and then axially squeezed to generate a certain negative pressure, so that the end annular contact surface of the bellows is adsorbed on the target surface, and then the first chamber 101 in the base 10 is subjected to negative pressure operation to generate a traction force of appropriate size, thereby achieving the goal of traction of the human body.

[0045] The utility model proposes a suction cup type traction device to solve the problem that there is no suitable equipment for body invagination correction and rehabilitation training of skin, body and even internal organs. At the same time, it has a simple structure, simple installation and disassembly, strong adaptability in practical application, can fit the complex shape and small area of ​​the human body, has good adsorption force and is not easy to leak, and can be well applied to the field of medical rehabilitation.
