Description

The adjustable support of riflery
Technical field
The utility model relates to a kind of riflery to be relied on, particularly a kind of can be according to the adjustable support of riflery of ejaculator's needs adjustment height.
Background technology
Rifle shooting training especially during the gunnery training of rifle prone position, need be provided with a support that is used to support rifle usually, makes armedly can keep stable, and allows the trainer can grasp correct aiming position.The support that general rifle prone position gunnery training is used is the base that adopts cement and timber to make, on base, place sandbag and put rifle, the rifle height of putting of its support is fixed on 25~30cm usually, and the gunnery training of this rifle prone position just can not change with the height that relies on is in a single day fixing.But because the individual difference of people's the bodily form when the support training of using same level altitude, can feel awkward, be difficult to grasp correct aiming position, even form wrong prone position, influence training effect and shooting grade.And the support of the clay work of water, because of it is heavier, also be not easy to carry and carry, when need cut in the training court, just increased the difficulty of transition.
At above-mentioned situation, the patent No. is that 200820098481.4 " rifle prone position shooting lift rely on " discloses a kind of lift and rely on, it comprises the support seat, base, be provided with the lifting column of circle center hole in the bottom fixedly connected that relies on seat, the upper end of lifting column is welded to connect plate, connecting plate is fastenedly connected in the lower end that relies on seat by screw, relying on the below of seat is base, erect in the base one threaded section rotating shaft is set, the fixedly connected support that is useful on supporting revolving shaft in the base, described support adopts the lateral frame plate that is fixedly connected in the base, this support is provided with the through hole that passes for rotating shaft, bearing is installed in the through hole, threaded section rotating shaft is slidingly matched by bearing and support, and dead eye is passed in the lower end of rotating shaft, and its axle journal is connected with bearing on being installed in base, threaded section rotating shaft can firmly be erected in the base, and be connected cooperation with base rotationally.The thread segment of threaded section rotating shaft is positioned at the circle center hole and the lifting column threaded engagement of lifting column.The circle center hole of described lifting column is made as shoulder hole, the miner diameter end of this shoulder hole is provided with internal thread, is positioned at the lower end of lifting column, with the thread segment threaded engagement of rotating shaft, bearing is set in the upper end of rotating shaft and lifting column is slidingly matched, and can not produce skew radially when making the lifting column lifting.For easy to make, the miner diameter end of described shoulder hole is formed by the nut that is weldingly fixed on the lifting column lower end; The axle of one handle and protuberate basic unit is connected, and is connected by the space gear drive between this axle and the rotating shaft.Described space gear drive adopts Bevel Gear Transmission mechanism, the axle of the driving gear of its Bevel Gear Transmission mechanism connects handle, this is by the bearings that is installed on the base inner supporting frame, and the driven gear of its Bevel Gear Transmission mechanism circumferentially is fixedly connected in the rotating shaft, is positioned at the below of support.Fixedly install guider on the support that is provided with in the described base, lifting column can circumferentially be limited in guider axially slidably.Described guider is the guide cylinder that is fixed on the support, and lifting column is arranged in guide cylinder, by concavo-convex be slidingly matched form can be along the guide cylinder axially-movable circumferentially spacing.The described concavo-convex structure that is slidingly matched is, the lifting column cylindrical is provided with chute vertically, the guide cylinder inwall is provided with slide rail vertically, by being slidingly matched of slide rail and chute, can limit lifting column circumferentially rotates, can make lifting column under the guiding of slide rail, do axial rising or descending motion again, drive the support seat that is attached thereto together thus and rise or descend.Can regulate the height that relies on seat easily though this lift relies on, to adapt to the people of the different bodily forms, because of its structure is complicated, cost of manufacture is higher.
Summary of the invention
