Description
Technical Field
The utility model relates to a connecting seat, in particular to a wear-resistant, stable and high-precision connecting seat convenient for a sighting telescope.
Background
Connecting seats in the industry of light arms are generally used for connecting a sighting telescope with a weapon, and after the sighting telescope is mounted on the connecting seats, the connecting seats can be rapidly clamped on various weapons and can be repeatedly clamped.
At present, the material of domestic connecting seats generally takes aluminum alloy, steel and titanium alloy as main materials, and after parts are formed, specific surface treatment can be carried out. When the connecting seat is repeatedly clamped, the clamping surface of the connecting seat is abraded due to multiple use, so that the service life of the connecting seat is shortened, and the corrosion resistance of the abraded contact surface is greatly weakened; in addition, clamping surface abrasion can also cause poor consistency of the clamping position of the sighting telescope, the zero position of repeated clamping possibly exceeds the standard, and under the condition that the requirement on the precision of repeated clamping of the connecting seat is high, the requirement on the use precision cannot be met even if the surface roughness of a part reaches Ra1.6.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a wear-resistant and stable high-precision connecting seat.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a wear-resistant stable high-precision connecting seat comprises a base, a screw rod, a pressing block, a flat washer, an elastic washer and a locking nut, and is characterized in that the bottom surface of the base is in contact with an installation guide rail of a sighting telescope, and a wear-resistant layer I is arranged at the contact position of the bottom surface of the base; the lower part of the base is provided with two bosses, one end face of each of the two bosses is in contact with the mounting guide rail of the sighting telescope, and the contact end faces of the two bosses are provided with a second wear-resistant layer; one end of the base is in contact with the pressing block, and a third wear-resistant layer and a fourth wear-resistant layer are arranged at the contact position of the base and the pressing block, wherein the third wear-resistant layer is positioned on the contact surface of the base, and the fourth wear-resistant layer is positioned on the contact surface of the pressing block; the lower part of the pressing block is in contact with the mounting guide rail of the sighting telescope, and a wear-resistant layer V is arranged at the contact position of the lower part of the pressing block.
Further, the screw rod is arranged from one side of the base 1, and the pressing block, the flat washer and the elastic washer are sequentially arranged on the screw rod.
Further, the end of the screw is rotationally compressed by a lock nut.
Further, the base is made of aluminum alloy, stainless steel or titanium alloy.
Further, the pressing block is made of aluminum alloy, stainless steel or titanium alloy.
Compared with the existing connecting seat, the connecting seat has the advantages that:
1. the wear-resistant layers are arranged at multiple positions, so that the wear resistance and the corrosion resistance of the connecting seat are greatly improved, and the service life of the connecting seat is prolonged.
2. Through detecting, after setting up the wearing layer, can improve the microhardness of connecting seat contact surface more than 20% to the deformation of connecting seat contact surface when having reduced the clamping has promoted the uniformity of repeated clamping, can satisfy the operation requirement of higher accuracy.
