Embodiment Construction

[0014] Examples, see figure 1 with figure 2 Shown: anti-sway bolt, including screw rod 10 and head 20. The head 20 is mostly in the shape of a hexagonal cylinder or is provided with a "one" or "ten" sinker. The outer surface of the screw 10 is provided with an external thread 11 .

[0015] Furthermore, the lower end of the screw 10 is provided with a downwardly opening receiving groove 12 , and a cover 13 is welded on the outside of the receiving groove 12 , and a through hole 131 with a diameter smaller than that of the receiving groove 12 is opened on the cover 13 . Obviously, the cross section of the receiving groove 12 is circular. The anti-sway bolt also includes a top post 30 . The top column 30 includes a column body 31 and a big head 32 located on the upper end of the column body 31 . The big head 32 is also cylindrical. The big head 32 is slidably disposed in the receiving groove 12 , and the cylinder 31 passes through the through hole 131 from top to bottom wi...

Abstract

The invention discloses a catch bolt. The catch bolt comprises a screw, a head, a jack-prop and an inverted trapezoidal cushion block, wherein outer threads are arranged on the outer surface of the screw; an accommodating groove of which an opening is downward is formed in the lower end of the screw; a cover is welded to the outside of the accommodating groove; a through hole of which the diameter is smaller than that of the accommodating groove is formed in the cover; the jack-prop comprises a prop body and a large head positioned at the upper end of the prop body; the large head is slidably arranged in the accommodating groove; the prop body penetrates through the through hole from top to bottom in a clearance fit manner; a first pressure spring is arranged between the large head and the bottom of the accommodating groove; a recess of which an opening faces upwards is formed in the upper side surface of the cushion block; meanwhile, a slot is formed in the upper part of the screw; the height of the slot in the vertical direction is greater than the height of the cushion block; the cushion block is positioned in the slot; a second pressure spring is arranged in the recess; and the upper end of the second pressure spring is propped against the upper part of the slot. The catch bolt has the advantage that the bolt can be effectively prevented from shaking.

Description

technical field [0001] The invention relates to the technical field of mechanical accessories, in particular to an anti-sway bolt. Background technique [0002] There must be a gap between the screw rod and the screw hole, so the bolt in use is very easy to shake. Especially for bolts whose screw rods cannot be fully screwed into the screw holes due to assembly requirements. That is to say, this situation is more pronounced for bolts which only have the threaded rod partly located in the threaded hole. Apparently, a bolt that is prone to wobbling makes the parts it connects unstable, and the bolt can easily fall off by itself. Contents of the invention [0003] The object of the present invention is to provide an anti-sway bolt, which has the characteristics of effectively preventing the bolt from swaying. [0004] The technical solution adopted in the present invention is: the anti-sway bolt includes a screw rod and a head, the outer surface of the screw rod is provide...
