Abstract
Description
Technical Field
[0001] The utility model relates to a 3D rehabilitation training system, in particular to a connection structure between a support frame and a top cover of a 3D rehabilitation training system, belonging to the field of mechanical technology. Background Art
[0002] The 3D rehabilitation training system is used for balance function and postpartum training of pregnant women. The applicant has conducted in-depth research and development on such training equipment, and innovative solutions have been continuously proposed and disclosed in Chinese patent applications, such as a multifunctional postpartum rehabilitation training system disclosed in 2018103892352, a balance training platform integrating testing and active and passive training disclosed in 2019109908965, etc. There are support frames around the 3D rehabilitation training equipment. The support frames are fixedly connected with a top frame for installing auxiliary training equipment such as footrests, display devices, and suspension straps. The basic main body of the support frame is the structure disclosed in 2018103892352. A support column is fixedly installed near each of the four corners of the training platform. A plurality of horizontal support rods are fixedly connected between the two support columns at the front and between the two support columns at the rear for support. Since the support frame and the top frame are relatively large and it is quite difficult to manufacture integrally, the top frame is generally fixedly assembled on the support frame. The top frame is a long-shaped frame structure similar to a bathtub (groove type). Connection structures are arranged at the lower ends of the four corners of the top frame for assembly with the support columns. The initial assembly structure adopted a connection similar to the thread and nut connection between two pipe joints. This connection method requires high precision. The top frame is very easy to be deformed by heat during the manufacturing and welding process and it is very difficult to maintain the designed shape. Therefore, a great deal of manual effort is often required to dock during assembly. If the deformation is large, it is also necessary to correct it by means of knocking, etc. The installation is very laborious. And after the installation, due to the restraint of the top frame during the installation process, it has a stretching deformation force, which is easy to drive the entire support frame to deform and affect the use of the equipment. Summary of the Invention
[0003] The purpose of the utility model is to overcome the above problems existing in the current 3D rehabilitation training system and provide a connection structure between a support frame and a top frame of a 3D rehabilitation training system.
[0004] To achieve the object of the present utility model, the following technical solution is adopted: a connection structure between the support frame and the top frame of a 3D rehabilitation training system. The support frame includes four support columns respectively arranged in a rectangular shape. The top frame is in a trough-shaped frame structure. Four connecting rods respectively corresponding to the support columns are fixedly arranged on the top frame. An upper flange is fixedly connected to the connecting rod, and a lower flange is fixedly connected to the support column. A plurality of corresponding connection holes are provided on both the upper flange and the lower flange. The connection holes on the upper flange are radial strip holes or circumferential arc holes. When the connection holes on the upper flange are radial strip holes, the connection holes on the lower flange are circumferential arc holes. When the connection holes on the upper flange are circumferential arc holes, the connection holes on the lower flange are radial strip holes. After the upper flange and the lower flange are butted, the connection holes of the two are in a "cross" intersection. Bolts are inserted into the connection holes of the upper flange and the lower flange, and nuts are screwed onto the bolts to lock.
[0005] Further, a limiting ring is fixedly connected or integrally arranged on the lower flange. The center of the limiting ring is concentric with the lower flange. The radial dimension of the limiting ring is larger than that of the upper flange. After the upper flange and the lower flange are butted, the upper flange is located in the limiting ring.
[0006] Further, there are four connection holes on both the upper flange and the lower flange.
[0007] The positive and beneficial technical effects of the present utility model are as follows: This connection structure is firm and reliable, has a large tolerance, is convenient for installation and adjustment, and is not easily deformed after connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] To more fully explain the implementation of the present utility model, implementation examples of the present utility model are provided. These implementation examples are only for the elaboration of the present utility model and do not limit the scope of the present utility model.
[0014] The present utility model is further explained in detail in conjunction with the drawings. The marks in the drawings are: 1: support frame; 2: support column; 3: top frame; 4: connecting rod; 5: limiting ring; 6: upper flange; 7: arc hole; 8: lower flange; 9: strip hole.
[0015] As shown in the attached drawings, the connection structure between the support frame and the top frame of the 3D rehabilitation training system. The support frame includes four support columns 2 that are respectively rectangular. The top frame 3 is in a trough-shaped frame structure. Four connecting rods 4 corresponding to the support columns are fixedly arranged on the top frame 3. An upper flange 6 is fixedly connected to the connecting rod. A lower flange 8 is fixedly connected to the support column. A plurality of corresponding connection holes are provided on both the upper flange and the lower flange. In this embodiment, there are four connection holes on both the upper flange and the lower flange. The connection holes on the upper flange are radial strip holes or circumferential arc holes. When the connection holes on the upper flange are radial strip holes, the connection holes on the lower flange are circumferential arc holes. When the connection holes on the upper flange are circumferential arc holes, the connection holes on the lower flange are radial strip holes. In this embodiment, the connection holes on the upper flange are circumferential arc holes 7, and the connection holes on the lower flange are radial strip holes 9. After the upper flange and the lower flange are butted, the connection holes of the two are in a "cross" shape. Bolts are inserted through the connection holes of the upper flange and the lower flange, and nuts are screwed onto the bolts to lock. A limit ring 5 is fixedly connected or integrally provided on the lower flange. The center of the limit ring 5 is concentric with the lower flange 8. The radial dimension of the limit ring is larger than that of the upper flange. After the upper flange and the lower flange are butted, the upper flange is located in the limit ring.
[0016] When installing with this structure, during installation, first install the upper flange and the lower flange on one side, insert the bolts and nuts but do not tighten them. Then, after aligning the end faces of the upper flange and the lower flange on the other side, penetrate the bolts through both of them, and then lock all the nuts. Using this installation method for the whole machine support frame can ensure that the top support frame can be normally installed on the basis of a certain deformation amount.
