Abstract

The invention discloses an anti-loosening bolt for a T-shaped nail. The anti-loosening bolt comprises a bolt rod (1), a standard nut (2), an anti-loosening gasket (3) and a T-shaped nail (4), and is shown in a figure 1 described in the specification, wherein an inverted inner thread hole is drilled in the tip axle center of the standard bolt rod in the bolt rod (1), and is shown is the figure 1; the anti-loosening gasket (3) is a hexagonal gasket of which the inner circle diameter is slightly greater than the diameter of the bolt rod; one end of the gasket is provided with a square groove which is shown in a figure 3; the T-shaped nail (4) is shown in a figure 4; the size of a transverse rod of the T-shaped nail is matched with that of the square groove of the gasket (3); a screw rod of the T-shaped nail is matched with the inverted inner thread hole; after a component is tightened by using the standard nut (2), the transverse rod of the T-shaped nail (4) is inserted into the square groove of the anti-loosening gasket (3), and is reversely screwed into an inner thread hole of the bolt rod end till the transverse rod is screwed tightly; and if the nut (2) becomes loose, the T-shaped nail (4) is driven to rotate in the same direction, and the rotation direction is a direction in which the T-shaped nail (4) is screwed, so that the nut (2) is prevented from becoming loose, and the aim of preventing the bolt from becoming loose is fulfilled.

Description

T sprig chek bolt

[technical field]

The present invention relates to a kind of bolt, especially chek bolt.

[background technique]

The prior standard bolt is to use double nut mostly when realization is locking, though this mode can play certain anti-loosing effect, because of two nut rotation directions are identical, turn does not simultaneously reach and guarantees locking purpose sometimes.

[summary of the invention]

The purpose of this invention is to provide a kind of chek bolt of guaranteeing anti-loosing effect that plays.

For realizing above-mentioned purpose, T sprig chek bolt of the present invention is made up of tightening latch 1, standard nut 2, lock washer 3, T sprig 4, sees Fig. 1.Tightening latch 1 is to bore a reverse interior threaded hole at place, axle center, standard tightening latch termination, sees Fig. 1; Lock washer 3 is packing rings that an interior circular diameter is slightly larger than tightening latch diameter, external form six sides, has square groove at an end of packing ring, sees Fig. 3; T sprig 4 is seen Fig. 4, and the square groove size of its cross bar size and packing ring 3 matches, and its screw rod matches with reverse interior threaded hole.After standard nut 2 is tightened member,, oppositely be screwed into the interior threaded hole of tightening latch end, until tightening with the square groove of T sprig 4 cross bars embedding lock washer 3.Like this, loosening if nut 2 produces, can drive T sprig 4 and rotate in the same way, and this rotation direction direction of T sprig 4 precessions just, thereby stoped becoming flexible of nut 2, reached the purpose that prevents bolt looseness.

[description of drawings]

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.Wherein:

Fig. 1 is the assembly side schematic view of T sprig chek bolt of the present invention.

Fig. 2 is the standard nut schematic representation of T sprig chek bolt of the present invention.

Fig. 3 is the lock washer schematic representation of T sprig chek bolt of the present invention.

Fig. 4 is the T sprig schematic representation of T sprig chek bolt of the present invention.

Wherein reference character is represented respectively: 1-tightening latch, 2-standard nut, 3-lock washer, 4-T sprig.

[embodiment]

For T sprig chek bolt, during use, screw in earlier standard nut 2, tighten member after, oppositely screwing in the phase embedding again is the lock washer 3 and T sprig 4 of one, until tightening T sprig 4, lock washer 3 and nut 2 is fitted tightly.Because T sprig 4 processes are limited, need confirm by the accurate thickness of connector element when selecting bolt length.
