Problems solved by technology

[0002] Filters generally require screws as tuning devices, and the general locking structure uses studs and nuts to lock in the filter. The installation and tuning of existing devices is troublesome, and the tuning screw is easy to loosen, which affects product quality; in order to overcome the problems caused by easy loosening of the screw Influence, self-locking screws are mostly used at present
By cutting grooves on the screw rod and turning the threads that are staggered at both ends, the axial force is generated at the groove position, so as to achieve the purpose of locking; the existing but unavoidable problems in debugging during use and opening in the middle of the thread due to inconsistent workpiece quality There will be burrs in the groove, which will affect the stability of the torque

Embodiment

[0014] Such as Figure 1 to Figure 3 As shown, a 5G self-locking tuning nut includes a nut body 100; the inner ring of the nut body 100 is tapped with a thin thread; the outer ring of the nut body 100 is provided with at least one concave point (101); the concave point 101 squeezes the inner ring to deform the thread of the filament. The practical automatic closing machine clamps a plurality of concave points 101 on the outer ring of the nut body 100, and squeezes the material into the nut, so that the thread tapped in the nut is deformed.

[0015] On the basis of the above, there are three concave points 101, which are evenly distributed on the outer ring of the nut body 100; the nut body 100 is provided with a silver-plated layer and a wax-coated layer.

[0016] The present invention deforms the thread to generate torque by pressing a point on the outer ring of the nut, and the depth and size of the pressure point can be adjusted to control the torque; the nut torque of the...

Abstract

The invention discloses a 5G self-locking tuning nut. The 5G self-locking tuning nut comprises a nut body; a fine thread is tapped on the inner circle of the nut body; at least one concave point (101)is arranged on the outer circle of the nut body; the concave points are extruded towards the inner circle to deform the fine thread; the three concave points are uniformly distributed on the outer circle of the nut body; and the nut body is provided with a silver coating and a waxing layer. According to the 5G self-locking tuning nut, the thread is deformed to generate torque through point pressing on the outer circle of the nut, and the torque can be controlled through adjustment of the point pressing depth and size; the nut is good in torque stability, the defects that an existing tuning device is difficult to debug and the torque is affected by slotting burrs in the middle of the thread are overcome, torque fluctuations are small, and an oscillogram is stable.

Description

technical field [0001] The invention relates to a filter tuning part, in particular to a 5G self-locking tuning nut. Background technique [0002] Filters generally require screws as tuning devices, and the general locking structure uses studs and nuts to lock in the filter. The installation and tuning of existing devices is troublesome, and the tuning screws are easy to loosen and affect product quality; in order to overcome the problems caused by easy loosening of the screws At present, self-locking screws are mostly used. By cutting grooves on the screw rod and turning the threads that are staggered at both ends, the axial force is generated at the groove position, so as to achieve the purpose of locking; the existing but unavoidable problems in debugging during use and opening in the middle of the thread due to inconsistent workpiece quality There will be burrs in the groove, which will affect the stability of the torque. Contents of the invention [0003] The techni...
