Specifically, the gate device comprises the device for adjusting the assembly clearance of the gate movement. The gate device is more stable in work due to the arrangement, and the problem that the swing door slightly shakes when the swing door stops is effectively avoided.
Example one
As shown in fig. 1, the surface of the deformation structure 41 engaged with the spline 20 is used as a pressing surface 411, and the pressing surface 411 gradually approaches the central axis of the hollow structure in the direction away from the rotating shaft structure 30. By the arrangement, when the spline 20 gradually extends into the hollow structure, the abutting pressure of the abutting surface 411 on the spline 20 is gradually increased, so that the gap between the spline 20 and the swing arm lower sleeve 10 is eliminated, and the relative rotation between the spline 20 and the swing arm lower sleeve 10 is effectively avoided.
As shown in fig. 1, the spline 20 has a bearing surface 21 matching with the pressing surface 411, and the bearing surface 21 gradually approaches to the central axis of the hollow structure in the direction away from the rotating shaft structure 30. The arrangement is such that the bearing surface 21 and the pressing surface 411 form a guiding fit, so that the spline 20 can extend into the hollow structure to be matched with the matching surface.
As shown in fig. 1 and 3, the deformation structure 41 is formed by a bent plate-shaped structure, the bent plate-shaped structure includes an installation section 412 and a deformation section 413 which are sequentially connected and arranged at an angle, the installation section 412 is attached to the inner wall, and the deformation section 413 abuts against the surface of the spline 20.

When the spline 20 is installed in the hollow structure, the distance between the deformation segment 413 and the installation segment 412 is changed, so that the deformation segment 413 is pressed on the bearing surface 21 to eliminate the gap between the spline 20 and the swing arm lower sleeve 10.
As shown in fig. 1 and fig. 3, the bent plate-like structure is V-shaped, and a side surface of the deformation section 413 facing away from the mounting section 412 has a pressing surface 411.

The fixing member 42 passes through the swing arm lower assembly 10 and the mounting section 412 in turn, so that the mounting section 412 is fixedly connected with the swing arm lower assembly 10.
It should be noted that the periphery of the fixing member 42 has threads, fixing holes are formed in the swing arm lower sleeve 10 and the mounting section 412, and threads are formed on the inner walls of the fixing holes, so that the fixing member 42 is in threaded connection with the swing arm lower sleeve 10 and the mounting section 412.

As shown in fig. 1, the deformation structure 41 further includes a deformation adjusting structure 414, and the deformation adjusting structure 414 passes through the sidewall of the swing arm lower assembly 10 and extends to the deformation section 413, so that the deformation section 413 compresses the spline 20 under the pressing force of the deformation adjusting structure 414. The pressure of the deformation section 413 on the spline 20 can also be adjusted by the arrangement of the deformation adjusting structure 414, so that the risk of shaking between the spline 20 and the swing arm lower sleeve 10 is avoided. Meanwhile, the deformation adjusting structure 414 is arranged to form supporting force for the deformation section 413, so that the deformation section 413 is prevented from shaking, the shaking of the swing arm lower sleeve 10 is avoided, and the working stability of the swing arm lower sleeve 10 is improved.
As shown in fig. 1 and 3, the length of the deformation section 413 is greater than that of the mounting section 412, so that the free end of the deformation section 413 has an adjusting contact surface 415 matched with the deformation adjusting structure 414, and the deformation adjusting structure 414 is spaced from the mounting section 412. Set up like this and make deformation adjust structure 414 only with deformation section 413 contact, and need not to pass installation segment 412 to make deformation adjust structure 414 only to deformation section 413 application of force, avoid deformation to adjust structure 414 simultaneously to installation segment 412 and deformation section 413 application of force simultaneously, can effectively avoid the cracked risk of installation segment 412, increased stability and the security that deformation structure 41 used.
It should be noted that the deformation adjusting structure 414 passes through the side wall of the swing arm lower assembly 10 and then extends into the hollow structure to abut against the adjusting contact surface 415, so as to prevent the deformation section 413 from shaking.
