Abstract
The invention discloses a locking bolt which comprises a screw rod (1) and a nut (2), and is characterized by further comprising a gland (3), a flat key (4) and an inner hexagon screw (5), wherein a key groove is formed in the surface of an excircle at the lower part of the screw rod (1); a threaded hole is formed in the middle of the lower end of the screw rod (1); the gland (3) is connected with the screw rod (1) via the flat key (4); the inner hexagon screw (5) is mounted in the threaded hole of the screw rod (1); and the gland (3) is compressed on the lower end surface of the nut (2). The locking bolt is convenient to dismount, good in locking effect, low in cost, long in service life, safe and reliable.
Description
Technical field
The present invention relates to fastening piece, specifically a kind of chek bolt.
Background technique
Existing screw retention mostly adopts the form such as slotted nut or lock washer, and this form is installed and comparatively bothered, and is having the occasion of vibrations, sometimes produces and loosens 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.
Summary of the invention
Object of the present invention 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 present invention includes 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 is pressed on the lower end surface of nut by gland.
The present invention is owing to have employed 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 circumference of gland from rotating, and socket head screw can prevent moving axially of gland, like this, the nut being glanded compression just can not have rotated, thus plays locking effect.Convenient disassembly of the present invention, 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 invention.
Embodiment
