Description
Technical field
The utility model is related to a kind of check bolt, belongs to mechanical equipment technical field.
Background technology
Plain bolt can bear load laterally and axially, and its horizontal load method of bearing is relied primarily on by pre-fastening moment
The frictional force brought, but in the presence of shock and vibration or varying load, the frictional force between screw pair may be gradually reduced
Or disappear, while the axial ability to bear of bolt will also be greatly lowered or even disappear, after such case repeatedly occurs, bolt is just
The phenomenon released automatically occurs, this will cause extremely serious consequence in actual life, produces great potential safety hazard,
And currently used bolt Relaxation Methods, there is complicated, the more material of consumption, installation wastes time and energy, some anti-loose measures
Method also needs to destroy original screw thread pair so that can not dismantle nut in maintenance so that nut and screw rod can not be recycled,
Therefore we introduce a kind of check bolt with resilient key and can effectively avoid disadvantages described above herein.
Utility model content

The utility model discloses a kind of check bolt, including screw rod and nut, there is threaded portion, spiral shell in one end of screw rod
The one end of line portion away from screw rod is connected with Access Division, and Access Division is provided with block tongue, Access Division and threaded portion coaxial line and block tongue can
Along the radial expansion of Access Division；There is the screwed hole and stepped hole of coaxial line, screwed hole coordinates with threaded portion, platform on nut
The aperture in rank hole is more than screwed hole and is engaged by clamping with Access Division.
In the structure, the structure that can be engaged by clamping in the stepped hole of screw rod is set in one end of screw rod, realizing is needing to connect
When connecing, screw rod can be quickly connected with nut, while effective placing nut is released from bolt, additionally it is possible to when needing to remove
Block tongue is shunk, so as to ensure the dismounting of nut and screw rod.
Further, Access Division is provided with mounting hole radially, and block tongue is placed in mounting hole and stretches out the mounting hole, pacifies
Fill and spring is provided with hole, spring is butted on block tongue to hinder block tongue to stretch into mounting hole.The mounting hole can use blind hole or through hole,
Can effectively ensure that block tongue can move radially, it is ensured that the validity of clamping.
Further, provided with 2-4 block tongue on Access Division, each block tongue is installed by its corresponding mounting hole respectively.Should
The design of many block tongues, it is ensured that the fastness of clamping, so as to improve the flexibility of block tongue.
Further, when block tongue is in stretching state, block tongue can cover the screw thread of threaded portion along the axis direction of Access Division.Should
Block tongue exceedes threaded portion in structure, so as to ensure the clamping of block tongue, it is ensured that the normal of block tongue is used.
Further, the block tongue is wedge shaped, and the wedge-shaped inclined-plane is back on threaded portion.The wedge-shaped block tongue can be convenient to
External force is acted on, and makes block tongue to Access Division contract, so as to ensure effective dismounting of nut.
Further, the stepped hole includes macropore and aperture, and the aperture ratio of macropore and aperture is not less than 1.1；Aperture and spiral shell
Pit coaxial line is connected and connected；Macropore connects the outside of nut.
Further, the stepped hole can be replaced the neck for being matched with block tongue, when nut is connected to screw rod, block tongue and card
Groove correspondence is engaged by clamping.Block tongue can be fixed using neck, the interface arrangment for coordinating block tongue is more various, realizes the clamping of block tongue
Fixing.Rubber antiskid pad is provided with stepped hole, rubber antiskid pad is used for the anti-skidding of block tongue.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. make after nut is connected with screw rod, to prevent from loosening, additionally it is possible to be convenient to the dismounting of screw rod and nut, realize anti-
The secondary utilization of loose bolt；
2. screw rod and nut use thread fiting mode, nut is securedly mounted on screw rod, be located at block tongue on screw rod with
Stepped hole aligns, so as to limit the loosening of nut in use, can be effectively prevented from releasing and undertaking certain for nut
Axial force, have higher security.
