Description
Technical field
The utility model relates to a kind of anti-loose structure, relates in particular to a kind of threaded cap anti-loose structure.
Background technology
The mode of locking thread can be divided into two classes, and a class is that friction force is locking, and another kind of is that machinery is locking.The locking restriction that can not be subject to position of rotation of friction force, but its locking fiduciary level is often be not as locking as machinery; And the locking restriction that is usually subject to position of rotation of machinery.
Utility model content
The utility model discloses a kind of threaded cap anti-loose structure, low in order to solve in prior art threaded anti-loosing structure fiduciary level, easily receive the problem of the restriction of position of rotation.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A threaded cap anti-loose structure, wherein, comprising: a threaded cap is threaded with a housing, and described threaded cap and described housing have opposing sidewalls: a madial wall and a lateral wall.Described madial wall has the detent projection of a plurality of one-tenth circumference array; A plurality of holding screws offset through described lateral wall and described detent projection.
Threaded cap anti-loose structure as above, wherein, a plurality of described detent projection join end to end.
Threaded cap anti-loose structure as above, wherein, the cross section perpendicular to the axis of thread of described detent projection is: one section of a line segment is connected with described madial wall, and the other end of described line segment connects a vortex filament section.
Threaded cap anti-loose structure as above, wherein, the point of connection of described line segment and described madial wall is placed in described vortex filament section within the scope of described madial wall vertical projection.
Threaded cap anti-loose structure as above, wherein, described detent projection is arranged on described threaded cap, and a plurality of described holding screws offset through described housing and described detent projection.
Threaded cap anti-loose structure as above, wherein, described whirlpool line segment direction and threaded cap unscrew opposite direction.
Threaded cap anti-loose structure as above, wherein, described detent projection is arranged in described housing, and a plurality of described holding screws offset through described threaded cap and described detent projection.
Threaded cap anti-loose structure as above, wherein, it is identical that described vortex filament section and threaded cap unscrew direction.
Threaded cap anti-loose structure as above, wherein, described in each, holding screw all vertically points to the axis of thread; Angle between any two adjacent described holding screws is not equal to angle and the integral multiple thereof that the straight line of the axis of thread is pointed at described vortex filament section two ends.
In sum, owing to having adopted technique scheme, it is low that the utility model has solved in prior art threaded anti-loosing structure fiduciary level, easily receive the problem of the restriction of position of rotation, by detent projection and holding screw are set, make threaded cap rotate to arbitrarily position and further fix, this structure can produce to it effect of mechanical type locking thread.
Accompanying drawing explanation
Fig. 1 is the structural representation of the state one of the utility model threaded cap anti-loose structure:
Fig. 2 is the structural representation of the state two of the utility model threaded cap anti-loose structure;
Fig. 3 is the structure cutaway view of the utility model threaded cap anti-loose structure.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of the state one of the utility model threaded cap anti-loose structure, referring to Fig. 1, Fig. 2 is the structural representation of the state two of the utility model threaded cap anti-loose structure, refer to Fig. 1, Fig. 2, a kind of threaded cap 1 anti-loose structure, wherein, comprise: a threaded cap 1 is threaded with a housing 4, threaded cap 1 has opposing sidewalls with housing 4: a madial wall and a lateral wall.Madial wall has the detent projection of a plurality of one-tenth circumference array; A plurality of holding screws 2 offset through lateral wall and detent projection.
A plurality of detent projection of the present utility model joins end to end.
Further, higher for screw thread fixed precision or only need to carry out locking structure under tightening situation completely time, the utility model can adopt the structure that detent projection is set at part madial wall, detent projection can cover the interior side-wall surface that is less than 360 degree, makes can be fixed in the situation that tightening.
Further, when for the high structure of screw thread fixed precision, the utility model can adopt the structure that only has a detent projection, in the situation that tightening completely, tighten corresponding holding screw 2 and can prop up accurately detent projection, reach locking technique effect.
The cross section perpendicular to the axis of thread of detent projection of the present utility model is: one section of a line segment is connected with madial wall, and the other end of line segment connects a vortex filament section.
Further, the other end of line segment also can connect the short or linear portion of camber line, can reach locking technique effect equally.
The point of connection of line segment of the present utility model and madial wall is placed in vortex filament section within the scope of madial wall vertical projection.
Fig. 3 is the structure cutaway view of the utility model threaded cap anti-loose structure, refers to Fig. 3, and in an embodiment of the present utility model: detent projection of the present utility model is arranged on threaded cap 1, a plurality of holding screws 2 offset through housing 4 and detent projection.
Whirlpool of the present utility model line segment direction and threaded cap 1 unscrew opposite direction, make the utility model under holding screw 2 locking states, if threaded cap 1 is when unscrewing direction rotation, holding screw 2 can increase severely with the vortex filament part squeese pressure of detent projection, thereby stops screw thread to unclamp.
In another embodiment of the present utility model: detent projection of the present utility model is arranged in housing 4, a plurality of holding screws 2 offset through threaded cap 1 and detent projection.
It is identical that vortex filament section of the present utility model and threaded cap 1 unscrew direction, and its know-why is identical with embodiment before.
Each holding screw 2 of the present utility model all vertically points to the axis of thread; Angle between any two adjacent holding screws 2 is not equal to angle and the integral multiple thereof that the straight line of the axis of thread is pointed at vortex filament section two ends.
In sum, owing to having adopted technique scheme, it is low that the utility model has solved in prior art threaded anti-loosing structure fiduciary level, easily receive the problem of the restriction of position of rotation, by detent projection and holding screw are set, make threaded cap rotate to arbitrarily position and further fix, this structure can produce to it effect of mechanical type locking thread.
