Abstract
The utility model discloses a tooth-shaped self-locking screw sleeve which comprises a screw sleeve body. An external-thread part is arranged outside the screw sleeve body, an internal-thread part is arranged inside the screw sleeve body, a tooth-shaped part is arranged at one end of the external-thread part, a closing part is arranged at the other end of the external-thread part and located on the external-thread part, the tooth-shaped part and the external-thread part form an external structure of the screw sleeve, and a groove is formed in one end, close to the closing part, of the screw sleeve part. According to the tooth-shaped self-locking screw sleeve, due to the fact that a tooth-shaped structure is additionally arranged at one end outside a common self-locking screw sleeve, the screw sleeve can be matched with a base body and prevent the base body from rotating in the installation process, and besides, the screw sleeve is more stable in part installation performance and simple in structure, has installation locking torque, achieves a locating function, guarantees reliability of installation positions, avoids installation base body damage caused by rotation of the screw sleeve in the installation process, does not need a special installation tool, greatly improves installation efficiency, and can be widely popularized and applied in engine structural parts.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of parts that are threaded, and especially relates to a kind of profile of tooth self-locking thread insert.
Background technique
At present, in the many structural members of machinery industry connect, usually need a kind of threaded swivel nut to connect.And need to have locking, vibration proof at these connection parts, and the control of installation locking torque requires and positioning control is had relatively high expectations.Therefore how to design and a kind ofly have the swivel nut that self-locking moment can play the role of positioning again and connect, guarantee to install locking torque in claimed range, can make again that positional accuracy is guaranteed between the mounted configuration part simultaneously, true current problem demanding prompt solution.
The model utility content
For addressing the above problem, the utility model provides a kind of profile of tooth self-locking thread insert, by increasing parts of tooth in common self locking screw sleeve external structure, make the part installation capability more stable, have an installation locking torque, both guarantee the mounting point reliability, avoided simultaneously swivel nut rotation damage installation matrix in the installation process.
The purpose of this utility model is achieved by following technical solution.
A kind of profile of tooth self-locking thread insert described in the utility model, comprise the swivel nut body, described swivel nut body exterior is male thread portion, inside is female thread portion, be provided with parts of tooth at male thread portion one end, the other end is provided with mouth, and described mouth is positioned on the male thread portion, and parts of tooth and external thread part are grouped into the external structure of swivel nut.
Be provided with groove by mouth one end on the described swivel nut body.
The quantity of described groove is six.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by having increased parts of tooth and mouth at common self locking screw sleeve.Owing to increase the odontoid structure at the outside end of common self locking screw sleeve, in installation process with between matrix, work the rotation inhibiting effect that cooperates; Removed the clamp ring of common self locking screw sleeve, changed common self locking screw sleeve into swivel nut self closing in distortion by clamp ring locking and lock.During installation parts of tooth being inserted matrix is fixed, male thread portion and nut are used, female thread portion, mouth carry out self-locking, make the part installation capability more stable, simple in structure, have an installation locking torque, play simultaneously the effect of location, both guaranteed the mounting point reliability, avoided again swivel nut rotation damage installation matrix in the installation process, do not need special installation tool, improved installation efficiency.Can in engine structure spare, extensively promote the use of.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-female thread portion, 2-parts of tooth, 3-mouth, 4-groove, 5-male thread portion.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As shown in Figure 1, a kind of profile of tooth self-locking thread insert described in the utility model, comprise the swivel nut body, described swivel nut body exterior is male thread portion 5, inside is female thread portion 1, is provided with parts of tooth 2 at male thread portion 5 one ends, and the other end is provided with mouth 3, described mouth 3 is positioned on the male thread portion 5, and parts of tooth 2 and male thread portion 5 form the external structure of swivel nuts.
Be provided with groove 4 by mouth 3 one ends on the described swivel nut body.
The quantity of described groove 4 is six.
Profile of tooth self-locking thread insert described in the utility model is for to have increased parts of tooth and mouth at common self locking screw sleeve.Common self locking screw sleeve external structure is increased parts of tooth, make swivel nut in installation process with between matrix, work the rotation inhibiting effect that cooperates; Removed the clamp ring of common self locking screw sleeve, changed common self locking screw sleeve into swivel nut self closing in distortion by clamp ring locking and lock.During installation parts of tooth being inserted matrix is fixed, male thread portion and nut are used, female thread portion, mouth carry out self-locking, make the part installation capability more stable, simple in structure, have an installation locking torque, play simultaneously the effect of location, both guarantee the mounting point reliability, avoided again swivel nut rotation damage installation matrix in the installation process.Do not need special installation tool, greatly improved installation efficiency.
