Abstract
The utility model discloses an anti-loosening bolt. The anti-loosening bolt comprises a screw (1) and a nut (2) and is characterized in that the anti-loosening bolt further comprises a gland (3), a flat key (4) and an inner hexagon screw (5), the outer circle surface of the lower portion of the screw (1) is provided with a key groove, a threaded hole is formed in the middle position of the lower end of the screw (1), the gland (3) is connected with the screw (1) through the flat key (4), and the inner hexagon screw (5) is arranged in the threaded hole of the screw (1) and tightly presses the gland (3) to the lower end face of the nut (2). The anti-loosening bolt is convenient to detach, good in anti-loosening effect, safe, reliable, low in cost and long in service life.
Description
Technical field
The utility model relates to fastening piece, specifically a kind of chek bolt.
Background technique
Existing screw retention mostly adopts the forms such as slotted nut or lock washer, and this form is installed comparatively trouble, and is having the occasion of vibrations, sometimes produces loosening phenomenon, therefore locking insecure; In addition, if for the occasion of High Rotation Speed, because screw thread or packing ring expose, easily there is casualty accident.
Model utility content
The purpose of this utility model is just to provide that a kind of convenient disassembly, anti-loosing effect are good, safe and reliable, with low cost, the chek bolt of long service life.
For achieving the above object, the utility model comprises screw rod and nut, also comprise gland, flat key and socket head screw, the outer round surface of described screw rod bottom is provided with keyway, the neutral position of described screw rod lower end is provided with tapped hole, described gland is connected with screw rod by flat key, and described socket head screw is loaded in screw flight hole, and gland is pressed on the lower end surface of nut.
The utility model is owing to having adopted gland, flat key and socket head screw, gland is connected with screw rod by flat key, socket head screw is loaded in screw flight hole, and gland is pressed on the lower end surface of nut, flat key can prevent the circumferential rotation of gland, and socket head screw can prevent moving axially of gland, like this, the nut that is glanded compression just can not rotate, thereby plays locking effect.The utility model convenient disassembly, anti-loosing effect is good, safe and reliable, with low cost, long service life.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
