Example 1

As shown in fig. 1 and 2, the upright locking mechanism of the running machine disclosed in this embodiment includes an upright 1 and a connecting seat 2, and the side wall of the upright 1 is pivoted to the connecting seat 2 near the lower end thereof. Specifically, the side surface of the connecting seat 2, which is close to the upright post 1, is vertically extended with a rotating shaft 12, a through hole 13 is penetrated at the position of the side wall of the upright post 1 corresponding to the connecting seat 2, a bushing 14 is fixedly penetrated in the through hole 13, the rotating shaft 12 is rotatably penetrated in the bushing 14, the end part of the rotating shaft 12, which is far away from the connecting seat 2, is extended with a screw 15, and a locking nut 16 is screwed on the screw 15. In order to improve the locking effect of the lock nut 16, a gasket 17 sleeved on the screw 15 is arranged between the lock nut 16 and the end surface of the bushing 14 away from the connecting seat 2. One end of the bushing 14 adjacent to the connecting seat 2 protrudes from the side surface of the upright 1 adjacent to the connecting seat 2 and the protruding portion abuts against the side wall of the connecting seat 2, so that a space is kept between the opposite surfaces of the upright 1 and the connecting seat 2. The connecting seat 2 extends upwards with a deformable member 3, preferably a stainless steel sheet, the plate surface of which is parallel to the side of the upright 1 adjacent to the connecting seat 2. A space is maintained between the deformable member 3 and the opposite face of the column 1 to provide sufficient space for deformation of the deformable member 3. The side wall of the upright post 1 is provided with a through hole 4 corresponding to the position of the deformable member 3, a screw 5 is penetrated in the through hole 4, and a threaded hole 6 for screwing the screw 5 is formed in the position of the deformable member 3 corresponding to the through hole 4. After the screw 5 and the threaded hole 6 are screwed with each other, the deformable member 3 is bent towards the direction close to the upright post 1, so that a gap between a screw tooth of the screw 5 and a screw tooth of the threaded hole 6 is eliminated, and therefore the front and rear position shaking between the upright post 1 and the connecting seat 2 is avoided.

As shown in fig. 1, in order to further enhance the deformability of the deformable member 3, elastic deformation grooves 7 are formed at the joints between the two sides of the deformable member 3 and the connection base 2.

As shown in fig. 1, 2 and 3, in order to make the post 1 after the installation more stable, a sleeve 8 is arranged between the through hole 4 and the screw 5, the outer circumferential surface of the sleeve 8 is fixed in the through hole 4 in a welding manner, the screw 5 is arranged in the sleeve 8 in a penetrating manner, one end of the sleeve 8, which is close to the deformable member 3, protrudes out of the side wall of the post 1, which is close to the deformable member 3, which is close to the post 1, and a positioning groove 9 for inserting the end of the sleeve 8 is formed by taking the threaded hole 6 as the center, so that the relative position deviation between the through hole 4 and the threaded hole 6 is avoided, and the stability after the installation of the post 1 is further improved. The inner side wall of the positioning groove 9 is provided with a conical surface 10 in a surrounding manner so as to effectively guide the end part of the sleeve 8 to be inserted into the positioning groove 9. The end of the sleeve 8 remote from the deformable member 3 protrudes from the outer side wall of the upright 1 remote from the deformable member 3 so that the screw 5 can more firmly lock the threaded hole 6.

As shown in fig. 2, in order to avoid excessive outward turning of the upright 1, the deformable member 3 is provided with a limit bump 11 near the side of the upright 1 and at one side of the threaded hole 6 to prevent the end of the sleeve 8 near the deformable member 3 from being separated from the deformable member 3 along the rotation plane of the upright 1.

Example two

As shown in fig. 4 and 5, on the basis of the first embodiment, the present embodiment discloses a running machine with the locking mechanism of the upright 1, which comprises a running table 18, and the connecting seat 2 is fixed on one side of the running table 18 by welding. In order to enable the screw 5 to be screwed smoothly, the lateral surface of the running block 18 is provided with a relief hole 19 corresponding to the screw 5.

The following describes the principle of use of the upright locking mechanism of the running machine and the running machine with the locking mechanism in combination with the first and second embodiments:

when the running machine is in the storage state, the upright 1 and the running platform 18 are in a mutually folded state by virtue of the rotating fit between the rotating shaft 12 and the bushing 14. To install the treadmill, the upright 1 is lifted from the running platform 18, so that the upright 1 is in a vertical state, and the through hole 4 on the upright 1 is opposite to the threaded hole 6 on the deformable member 3. At this time, the screw 5 is threaded into the threaded hole 6 through the sleeve 8 from outside to inside. As shown in fig. 5, in the screwing process, the circumferential rotation between the screw 5 and the threaded hole 6 can be converted into relative linear motion between the screw and the threaded hole 6, so that the deformable member 3 deforms towards the direction close to the upright post 1 until the end part of the sleeve 8 close to the deformable member 3 is inserted into the positioning groove 9 along the conical surface 10, thereby eliminating the gap between the screw teeth of the screw 5 and the screw teeth of the threaded hole 6, and preventing the upright post 1 from shaking in the front-rear direction after the installation is completed. Not only the installation effectiveness of the upright column 1 is improved, but also the stability of the upright column 1 after installation is finished can be increased.

When it is desired to house the treadmill, the above steps are performed in reverse to unlock the sleeve 8 from the threaded hole 6, and the deformable member 3 is reset to disengage the end of the sleeve 8 from the positioning groove 9. Finally, the upright 1 is lowered to return the treadmill to the folded state (as shown in fig. 6).
