Description

A kind of gun rack march is fixed, clamps integrated device

Technical field

The present utility model is related to march fixation and the tensioning technique field of firearms technical field, especially gun rack.

Background technique

At present mounted in tank, plate armour, the vehicular machine gun on offroad vehicle require a height to march fixator, to support Various bumpy roads act on the damage of weapon in imperial vehicular motion.Vehicle, which jolts, drives weapon to jolt, if do not gone Army's fixator, the inertia force to jolt will be applied to weapon transmission portion and the gap increase of transmission portion caused to influence penetrating for weapon Hit precision；What is more will cause transmission system strength weak components braking effect weapon normal use.

In order to preferably protect weapon not damaged by march process moderately gusty air, generally first using march fixator reel cage Then reel cage and bracket are clipped together by clamp system again and are clamped by frictional force on bracket by lock.

There are two types of tradition march fixators, the first is the march retainer shaft that push on bracket by cylindrical compression spring Reel cage is lockked in march retainer hole on insertion reel cage, will be marched fixator when freeing by fixator handle pull-up of marching Axis is transformed into opening state (such as Fig. 1)；Second is rack form, bracket boosted when march allow bracket embrace gun barrel or Gun breech does not allow machine gun height to rotate (such as Fig. 2), but both the above form and height locking mechanism are all that separation causes to produce Product compact type is poor, quality weight.

Summary of the invention

In order to break through, tradition breaks through gun rack march fixator and the problem of locking mechanism cannot be combined into one, this is practical new The gun rack march of type is fixed and clamps integral structure, makes gun rack structure more compact, weight is lighter.

The present utility model technical solution is:

A kind of march of gun rack is fixed and clamps integrated device, which is characterized in that including bracket, reel cage arc plate, clamp shaft and Clamp shaft nut；Clamp shaft shape is bolt shape, and orchid is tried in left end, and right end is formed with screw thread, and clamp shaft nut is right loaded on clamp shaft End；Bracket and reel cage arc plate can be tightened by clamping axis connection by clamp shaft nut；Clamp shaft is hollow, snap-gauge axis peace Loaded in clamp shaft, clamp shaft inner surface and snap-gauge axis outer surface are equipped with opposite step, install between two opposite steps There is clamp plate spring；Snap-gauge axis left end is connected with snap-gauge, and reel cage arc plate is provided with the rectangular channel of corresponding snap-gauge, and the flange of clamp shaft is provided with pair The rectangular channel for answering snap-gauge, when two rectangular grooves are in same position, snap-gauge can be caught in realization locking.

The clamp shaft and the mutual corresponding position of bracket are equipped with card slot, are equipped with flat key in the card slot.Clamp shaft It will not rotate under flat key effect relative to bracket.

The flange of the clamp shaft is equipped with solution locked groove, is used for fixing chuck plate position.

The solution locked groove of the clamp shaft is equipped with 30 ° of rotary steering faces.

It is provided with clamping lever on the clamp shaft nut, for rotating clamp shaft nut.

Beneficial effect of the present utility model is that march fastener mechanism is closed two with clamp system and is by the utility model One, march fixed structure through inside clamp system, structure is simple, it is reliable, compact, save space and can reduce weight, shape again State conversion is easy, easy to operate；This structure can more be promoted the use of on manual vehicle-mounted, carrier-borne, airborne gun rack.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing

Embodiment 1

See Fig. 3, a kind of gun rack march of the utility model is fixed and clamps integrated device, including bracket 8, reel cage arc plate 9, Clamp shaft 2 and clamp shaft nut 4；2 left end of clamp shaft is flange, and right end has screw thread, and clamp shaft nut 4 is loaded on 2 right end of clamp shaft； Bracket 8 and reel cage arc plate 9 are connected by clamp shaft 2, and can be tightened by clamp shaft nut 4；Clamp shaft 2 is hollow, snap-gauge axis 5 It is installed in clamp shaft 2,2 inner surface of clamp shaft and 5 outer surface of snap-gauge axis are equipped with opposite step, between two opposite steps Clamp plate spring 3 is installed；2 left end of snap-gauge axis is connected with snap-gauge 1, and reel cage arc plate 9 is provided with the rectangular channel of corresponding snap-gauge 1, clamp shaft 2 Flange is provided with the rectangular channel (locking slot) of corresponding snap-gauge 1, and when two rectangular grooves are in same position, snap-gauge 1 can be caught in realization lock Tightly.

Embodiment 2

See Fig. 4, Fig. 5, Fig. 6, Fig. 7, on certain gun rack, opens in the rectangular channel of reel cage arc plate 9 and be in in its arc groove Fixed position march to trunnion direction, clamp shaft 2 flange rectangular groove in march position；Because clamp shaft 2 is installed on There is flat key 7 in the locking hole of bracket 8, between axis and hole, clamp shaft can horizontally slip, not be able to rotate；Clamp shaft 2 is hollow Axis, inside are installed with snap-gauge axis 5, snap-gauge 1 are connected on snap-gauge axis 5, and snap-gauge 1 can be rotated, and can control translation under the effect of clamp plate spring 3； When 1 pull-up of snap-gauge is put into the locking slot of clamp shaft 2, under spring tension effect, when reel cage goes to march position, snap-gauge 1 It falls into the rectangular channel of reel cage arc plate and locks reel cage, while clamping lever 6 can be moved clockwise under the effect of clamp shaft 2 Reel cage arc plate 9 is clamped with bracket 8；When needing to free, clamping lever 6 is counterclockwise pulled by reel cage arc plate 9 and bracket 8 It unclamps, is rotated clockwise in the solution locked groove for allowing snap-gauge to fall into clamp shaft from 8 inside pull-up snap-gauge 1 of bracket, i.e., it is openable.

Embodiment 3

Fig. 4, Fig. 5 are seen, when snap-gauge 1 is transformed into vertical direction i.e. pluggable reel cage arc plate 9 under the effect of 3 spring force of clamp plate spring The rectangular channel of rectangular channel and clamp shaft 2, reel cage arc plate 9 is plugged together with clamp shaft 2 together with；The phase under the effect of flat key 7 of clamp shaft 2 It will not rotate for bracket 8, thus together with reel cage arc plate 9 is securely fixed with bracket 8；When pull-up snap-gauge 1 rotates to Horizontal position, snap-gauge 1 unclamp clamping lever 6 from being detached in the solution locked groove being stuck on 2 outer end face of clamp shaft in clamp shaft 2, Reel cage arc plate 9 can be freely rotated.

Lock state dress, which changes only to need that snap-gauge 1 is rotated counterclockwise 90 ° from horizontal position with left hand, goes to vertical position card Plate 1 falls into lock slots；Because the solution locked groove of clamp shaft 2 is equipped with 30 ° of rotary steering faces, do not have to draw snap-gauge in state conversion 1 directly twists.

Embodiment 4

See Fig. 6, Fig. 7, clamped condition dress, which changes only to need to pull clockwise turn 60 ° of clamping lever 6 with the right hand, can pass through the right side Reel cage arc plate 9 and bracket 8 are clamped together by the trapezoidal thread of rotation；Releasing orientation dress, which changes, only to be needed to push clamping lever with the right hand 6, which turn 60 ° counterclockwise, to unclamp reel cage arc plate 9 and bracket 8.
