Top mount structure for air guns

Abstract

This invention relates to a top-rotating seat structure for air rifles, specifically within the field of pneumatic gun product technology. It includes a top-rotating seat, a top-rotating rubber sleeve, and an adjusting assembly for adjusting the tightness of the top-rotating rubber sleeve. The top-rotating seat has a cylindrical receiving cavity and is mounted on the barrel along the front-rear direction. The top-rotating rubber sleeve is disposed within the receiving cavity, with its axis parallel to the axis of the receiving cavity. The front end of the top-rotating rubber sleeve communicates with the barrel, and its rear end communicates with the compression chamber. The top of the inner wall of the top-rotating rubber sleeve has a protrusion for pressing down on the projectile. The adjusting assembly includes an adjusting ring and a dial, with the adjusting ring fitted onto the top-rotating rubber sleeve. This invention allows users to conveniently and precisely adjust the contact pressure between the top-rotating rubber sleeve and the projectile, fully adapting to different projectiles, improving the stability and reliability of the top-rotating effect, and enhancing the range and accuracy of the air rifle.

Claims

1. A top-rotating seat structure for an air gun, comprising a top-rotating seat, a top-rotating rubber sleeve, and an adjusting assembly for adjusting the tightness of the top-rotating rubber sleeve. The top-rotating seat has a cylindrical receiving cavity and is disposed on a gun barrel in a front-rear direction. The top-rotating rubber sleeve is disposed within the receiving cavity, and the axis of the top-rotating rubber sleeve is parallel to the axis of the receiving cavity. The front end of the top-rotating rubber sleeve is connected to the gun barrel, and the rear end of the top-rotating rubber sleeve is connected to a compression chamber. The top of the inner sidewall of the top-rotating rubber sleeve is provided with a protrusion for pressing down a projectile. The adjusting assembly includes an adjusting ring and a dial. The adjusting ring is sleeved on the top-rotating rubber sleeve, and the dial is used to control the movement of the adjusting ring to tighten or loosen the top-rotating rubber sleeve.

2. The upper rotating seat structure for an air gun as described in claim 1, wherein an arcuate groove is provided on the dial and is coaxial with it, and a trigger extending along its axial direction is provided on the outer wall of the lower part of the adjusting ring, and a follower shaft is provided at the end of the trigger away from the adjusting ring, the follower shaft being inserted into the interior of the arcuate groove.

3. The upper rotating seat structure for an air gun as described in claim 2, wherein the follower shaft is rotatably connected to the trigger, and the outer wall of the follower shaft fits against the inner wall of the arcuate groove.

4. The upper rotating seat structure for an air gun as described in claim 2, wherein the outer peripheral surface of the dial is provided with an anti-slip texture, and the side wall of the upper rotating seat is provided with an avoidance notch for exposing the dial.

5. The upper rotating seat structure for an air gun as described in claim 2, wherein the upper rotating seat is divided into a left housing and a right housing, and a rotating shaft is rotatably disposed between the left housing and the right housing, the rotating shaft extending along the width direction of the upper rotating seat, and the dial is mounted on the rotating shaft.

6. The upper rotating seat structure for an air gun as described in claim 1, wherein the outer wall of the upper rotating rubber sleeve is in close contact with the inner wall of the receiving cavity, and a protrusion provided on the inner wall of the upper rotating rubber sleeve extends radially therefrom.

7. The upper rotating seat structure for an air gun as described in claim 5, wherein a limiting block extending radially is provided on the outer wall of the upper rotating rubber sleeve, and limiting grooves for the limiting block to be inserted are provided on the outer walls of both the left and right housings.

8. The upper rotating seat structure for an air gun as described in claim 5, wherein the right housing is provided with a plurality of bolts extending toward the left housing, and the inner sidewall of the left housing is provided with a plurality of threaded sleeves into which the bolts are screwed.
