Abstract
The utility model is related to a kind of anti-loosening structure for thread connection.The anti-loosening structure for thread connection includes connected component top cover (1), mounting seat (2), spring base (3), spring (4), thimble (5) and screw (6).The top cover (1) is provided with screw thread, for mounting seat (2) connection.The locking groove of a circle is provided with top cover (1) outer ring, groove is circumferentially uniformly distributed, it is general to be no less than 20, can set according to actual needs.The spring base (3) is fixed in mounting seat (2) with screw (6).Thimble (5) withstands the groove on top cover (1) outer ring, for the locking thread on top cover (1) in spring base (3) using spring (4).Part needed for the structure is few, flexible form, convenience, reliable lock, efficiently solves the locking problem of relatively large helicitic texture and is not suitable for locking plate, fuse and the locking thread connection anti-loose problem of flow of metal mode, is that locking thread adds new anti-loosening locking mode.
Description
Technical field
The utility model is related to a kind of anti-loosening structure for thread connection.
Background technology
Threaded connection is a kind of extremely common part connected mode, is widely used among every engineering.But the connection
Mode can slowly fluff under the working environments such as vibration, impact, cause the failure of component function, or even bring potential safety hazard.Cause
This, threaded connection is general all along with certain locking mode.Conventional locking mode has that locking plate is locking, flow of metal is locking,
Beat and insure locking etc..But these locking modes have oneself application limitation, particularly in larger screwed part, restrict in
The size of part, shape, structure and position etc., above-mentioned locking thread mode are all less applicable, it is necessary to design a kind of new
The locking mode of screw-threaded coupling, in the modular construction not applied to for conventional locking mode, particularly relatively large threaded connection knot
In structure.
Utility model content
The purpose of this utility model is to provide a kind of anti-loosening structure for thread connection, it is adaptable to relatively large screw connection structure
With the screw connection structure for being not suitable for using conventional locking mode.
Technical solution of the present utility model：A kind of anti-loosening structure for thread connection, including connected component top cover (or its
His connection member), mounting seat, spring base, spring, thimble and screw.The top cover is provided with screw thread, for connecting with mounting seat
Connect, the spring base is screwed in mounting seat.The locking groove of a circle is provided with top cover outer ring, groove is circumferentially
It is uniformly distributed.Thimble is arranged in spring base, and the groove on top cover outer ring is withstood using spring, is prevented for the screw thread on top cover
Pine.
Groove on top cover outer ring is typically no less than 20, can set according to actual needs, is shaped as circular arc, central angle one
As be not less than 120 °, the size of circular arc is closed with thimble against the matching size of groove one end.
The screw thread pine that the spring force that spring withstands the applying of top cover upper groove can overcome the structure under the environment such as mechanical oscillation
De- moment of torsion.
The utility model beneficial effect：The utility model patent is applied to relatively large screw connection structure and is not suitable for adopting
It is that part connection can for threaded connection adds new locking mode and selection with the threaded connection of the locking mode of normal thread
New solution is provided by work.

Specific embodiment
The utility model patent is described in further detail below in conjunction with the accompanying drawings.Fig. 1 is screw thread of the present utility model
The appearance schematic diagram of connection anti-loose structure.Fig. 2 is anti-loosening structure for thread connection front section view of the present utility model.Fig. 3 is this
The anti-loosening structure for thread connection vertical view cutaway drawing of utility model.As illustrated, anti-loosening structure for thread connection bag of the present utility model
Include connected component top cover 1 (or other connection members), mounting seat 2, spring base 3, spring 4, thimble 5 and screw 6.Described
Top cover 1 is provided with screw thread, for being connected with mounting seat 2.The locking groove of a circle is provided with the outer ring of top cover 1, groove is along circle
Week is uniformly distributed, and is 28 in present embodiment.But, the unlimited number of the groove can set according to actual needs in this
It is fixed, it is general to be no less than 20.The design attitude of groove can not influence the installation of screw thread.Groove shapes on the outer ring of top cover 1 are circle
Arc, the central angle of circular arc is 120 ° in present embodiment, usually not less than 120 °, size and the top of thimble 5 groove one end of circular arc
Matching size close.
Thimble 5 is arranged in spring base 3, pushes up the groove that one end of groove is withstood on top cover 1 through the hole in mounting seat 2.
Thimble 5 is compressed with spring 4, and spring base 3 is fixed in mounting seat 2 by screw 6.
The spring force that spring 4 compresses thimble 5 is that, by calculating, the power that thimble 5 withstands the groove applying on top cover 1 is necessary
Screw thread release torque of the connected component under the environment such as mechanical oscillation can be overcome.
