Abstract

The utility model discloses a weapon turntable device. The weapon turntable device comprises an annular fixed ring and an annular movable ring which are matched with each other, wherein the movable ring is positioned inside the fixed ring; the matching surface of the fixed ring and the movable ring is provided with an annular cavity; primary roll balls which are connected into a ring are arranged in the cavity; a secondary roll ball is arranged between adjacent primary roll balls; the secondary roll balls are in tangential contact with the primary roll balls; and the diameter of each secondary roll ball is less than that of each primary roll ball. The weapon turntable device has the characteristics that the primary roll balls are rotated flexibly and the movable ring is rotated smoothly, so that the weapon turntable device can be widely applied to military vehicles.

Description

Weapon rotary disc device

Technical field

The utility model relates to the camion boarded parts, particularly relates to a kind of weapon rotary disc device.

Background technology

Certain military vehicle carries a kind of simple weapon rotary disc device; In use, the main ball of the cavity inside of fixed circle and moving-coil formation does not have the gap, phase mutual friction during motion; Thereby it is not smooth to cause weapon rotary disc to rotate; Even can't rotate, use very inconvenience, need to consider that a kind of novel weapon rotary disc structure of design solves this problem.

The utility model content

The purpose of the utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of weapon rotary disc device to be provided, make it have main ball and rotate flexibly, and moving-coil rotates characteristics smoothly.

A kind of weapon rotary disc device that the utility model provides; It is inboard that the moving-coil of deciding circle and ring-type that comprises the ring-type that cooperatively interacts, said moving-coil are positioned at fixed circle, and the mating surface of said fixed circle and moving-coil is provided with the cavity of ring-type; Be provided with the main ball that connects into ring-type in the cavity; It is characterized in that: be provided with a secondary ball between the adjacent main ball, said secondary ball contacts with main ball is tangent, and secondary ball diameter is less than main ball.

The weapon rotary disc device of the utility model; Have following beneficial effect: evenly fill the cavity that forms between fixed circle and the moving-coil at interval through using two kinds of balls of major-minor, secondary ball guarantees the spacing between the main ball, thus master's ball phase mutual friction when having solved dial rotation; It is not smooth to cause moving-coil to rotate; Even the problem that can't rotate, winner's ball is rotated flexibly, moving-coil rotates smooth and easy.

Description of drawings

Fig. 1 is the utility model weapon rotary disc device structural representation;

Fig. 2 is the structural representation of A-A section among Fig. 1;

Fig. 3 is that main ball cooperates the structural representation that rotates in the utility model weapon rotary disc device with secondary ball.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail, but this embodiment should not be construed as the restriction to the utility model.

Referring to Fig. 1 to Fig. 3, the utility model weapon rotary disc device comprises decides circle 1, moving-coil 2, main ball 4, secondary ball 5.

Saidly enclose 1 surely and be ring-type with moving-coil 2, said moving-coil 2 is positioned at decides circle 1 inboard, saidly encloses 1 surely and is provided with the cavity 3 of ring-type with the mating surface of moving-coil 2.The main ball 4 that connects into ring-type is located in the cavity 3, and a secondary ball 5 is located between the adjacent main ball 4, said secondary ball 5 and main ball 4 tangent contacts, and secondary ball 5 diameters are less than main ball 4.

When moving-coil 2 rotates, the motion under moving-coil 2 drives of main ball 4, the counter motion under both sides master's ball 4 frictional force drive of secondary ball 5, secondary ball 5 has guaranteed the gap between the main ball 4, and winner's ball is rotated flexibly, moving-coil rotates smooth and easy.

Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.

The content of not doing in this specification to describe in detail belongs to this area professional and technical personnel's known prior art.

Claims

1. weapon rotary disc device; The moving-coil (2) of deciding circle (1) and ring-type that comprises the ring-type that cooperatively interacts, said moving-coil (2) are positioned at decides circle (1) inboard, and the mating surface of said fixed circle (1) and moving-coil (2) is provided with the cavity (3) of ring-type; Be provided with the main ball (4) that connects into ring-type in the cavity (3); It is characterized in that: be provided with a secondary ball (5) between the adjacent main ball (4), said secondary ball (5) and tangent contact of main ball (4), secondary ball (5) diameter is less than main ball (4).
