UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of stainless steel foot cup of connection fastening to solve the problems in the above background.

[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of stainless steel foot cup of connection fastening, including foot cup base 1, with the screw rod 3 of foot cup base 1 connection and the nut 2 of locking, it is characterized by: the foot cup base 1 with screw rod 3 is equipped with mutually matched polygonal hole 101 and polygonal boss 301, polygonal boss 301 is equipped with below screw rod 3;The nut 2 below screw rod 3 above is equipped with adjustable tightness limiting block 4.

[0007] Further, the limiting block 4 includes a hole 401 and two symmetric locking bosses 403, a locking hole 404 is provided on the locking boss 403, and an opening 402 is provided between the locking bosses 403.

[0008] Further, the inner diameter of the hole 401 is smaller than the thread diameter of the screw rod 3, and a layer of rubber layer is covered in the hole 401.

[0009] Further, the locking hole 404 is penetrated by a locking screw 6, and a swallow nut 5 is used for locking.

[0010] Further, the height of the polygonal boss 301 is less than the thickness of the polygonal hole 101.

[0011] Further, the polygonal boss 301 is provided with a limiting plate 302 below.

[0012] The utility model has the following beneficial effects: first, the foot cup and the screw rod use polygonal limiting, then use the nut locking, avoid the vibration up and down nut loosening simultaneously, lead to the foot cup instability; second, the screw rod does not need to mill flat, once injection molding, reduce the processing procedure; third, the locking fixing mechanism is simple, reduced production cost.
