Further, the pear-shaped ring is composed of two circular arcs and tangents connecting the circular arcs, and the radiuses r1 and r2 of the circular arcs and the distance h between the two circle centers have the following relation: r1 ═ (1/2-3/4) R2; R2-R1 is not less than h not less than R1+ R2.

Further, the heads of the two pear-shaped rings are arranged vertically upwards and horizontally.

Furthermore, the pear-shaped ring is provided with a screw hole at the bottom and an adjusting bolt penetrating through the screw hole, and the adjusting bolt adjusts and fixes the position of the camera.

Furthermore, the pear-shaped ring is made of elastic metal materials.

Furthermore, the connecting device comprises a cross beam, a fixed sleeve, a fixed bolt and a nut; the fixed sleeve is U-shaped, the bottom of the clamping sleeve is fixed on the cross beam, the upper part of the clamping sleeve is wrapped outside the gun barrel, and the top of the clamping sleeve is fixed through fixing bolts and nuts penetrating through two ends of the clamping sleeve.

The application's utmost point simple correction mechanism will fix the cover parcel in the barrel outside when using, and the top is fixed through fixing bolt and the nut that passes both ends. The front fixing ring and the rear fixing ring are pear-shaped and elastic, the camera is placed in the two rings, and the transverse adjustment and the longitudinal adjustment of the axis of the camera can be realized by adjusting screws of the front fixing ring and the rear fixing ring, so that the two-dimensional correction of the direction of the camera is realized.

The invention has novel structure and convenient use, is suitable for the requirement of hanging the camera on guns with different sizes, can accurately lead the axis of the camera to be consistent with the axis of the gun barrel, and is simple, portable and reliable.

Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of this application and the above-described drawings, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

A minimal modification mechanism as shown in fig. 1 and 2, comprising: a connecting device and a correcting device.

The connecting device is used for fixing the correcting mechanism below a gun barrel of the gun, and comprises a cross beam 1, a fixing sleeve 2, a fixing bolt 3 and a nut 4. The fixed sleeve is U-shaped, the bottom of the fixed sleeve is fixed on the cross beam, the upper part of the fixed sleeve is wrapped outside the gun barrel, and the top of the fixed sleeve is fixed by fixing bolts and nuts which penetrate through two ends of the fixed sleeve.

The correction device includes: a front retainer ring 5 and a rear retainer ring 6. The front fixing ring and the rear fixing ring are two pear-shaped rings, each pear-shaped ring is composed of two circular arcs and tangent lines connecting the circular arcs, and the radiuses r1 and r2 of the circular arcs and the distance h between the two circle centers have the following relations: r1 ═ (1/2-3/4) R2; R2-R1 is not less than h not less than R1+ R2. The center of the small arc is the head, and the center of the large arc is the bottom.

The heads of the two pear-shaped rings face different directions and are perpendicular to the gun barrel and fixed on the connecting device, in the embodiment, the head of the front fixing ring faces one side, the connecting line of the centers of the two circular arcs is perpendicular to the cross beam, the head of the rear fixing ring faces upward, the connecting line of the centers of the two circular arcs is perpendicular to the cross beam, and the connecting line of the centers of the two circular arcs is perpendicular to each other. The connecting line of the circle centers of the large arcs of the front fixing ring and the rear fixing ring is parallel to the beam (namely, the circle center of the large arc is positioned right below the beam).

The pear-shaped ring is located the bottom and is provided with screw 7 to be provided with adjusting bolt 8 that passes the screw, adjusting bolt adjusts and fixes the position of camera 9. The camera passes through the front and rear fixing rings to be fixed and keeps the axis consistent with the gun barrel.

The pear-shaped ring is made of elastic metal materials, and the ring edge is in a belt shape and can be propped open by the camera and be restored to the original shape after the camera is taken out.

When the gun barrel fixing sleeve is used, the fixing sleeve is wrapped outside the gun barrel, and the top of the gun barrel fixing sleeve is fixed through fixing bolts and nuts penetrating through two ends of the gun barrel. The front fixing ring and the rear fixing ring are pear-shaped and elastic, the camera is placed in the two rings, and the transverse adjustment and the longitudinal adjustment of the axis of the camera can be realized by adjusting screws of the front fixing ring and the rear fixing ring, so that the two-dimensional correction of the direction of the camera is realized.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
