Abstract
The invention relates to a shotgun handguard and barrel locking mechanism comprising a handguard, an upper barrel, a lower barrel, and a middle fixing seat assembly. The upper barrel and the lower barrel are connected through the middle fixing seat assembly. The middle fixing seat assembly comprises a seat body, a spring, a steel ball, a handguard locking bar, a countersunk head screw set, a locking steel ball, and a handguard button seat. The spring and the handguard locking bar are symmetrically arranged in a stepped hole. Arc separation grooves are symmetrically provided close to a square recess on the handguard locking bar. The middle fixing seat assembly is closely connected with the handguard through a handguard locking seat. A locking groove corresponding to the locking steel ball is arranged in the inner side of the handguard locking seat. The mechanism provided by the invention has the advantages of simple structure and reasonable design. During a shotgun application process, impact load between the barrel and the handguard can be minimized, such that weapon hit precision can be improved. Also, the connection between the handguard and the barrel is more reliable, and detachment is more convenient.

Technical field
The present invention relates to the guard timber of a kind of shotgun, particularly shotgun and the retaining mechanism of gun barrel.
Background technology
At present, the guard timber of known shotgun and the connected mode of gun barrel be, at guard timber support plate base is housed, and is welded with tenon below gun barrel, gun barrel is installed in the back guarantees its relative position inconvenience by the locking of the spring clamping body on the support plate base on the support plate base of guard timber.Though this connected mode is reliable, exist the dismounting difficulty, the maintenance maintenance inconvenience because gun barrel directly contacts with guard timber, causes the accuracy at target of shotgun to reduce.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, be convenient to dismounting, the guard timber that flexibility is strong and the retaining mechanism of gun barrel.
In order to achieve the above object, the technical solution used in the present invention is: comprise guard timber, last gun barrel, following gun barrel and center fixed holder assembly, the described gun barrel of going up links to each other by the center fixed holder assembly with following gun barrel, described center fixed holder assembly comprises pedestal, spring, steel ball, the guard timber locking bar, the sunk screw group, locking steel ball and guard timber push-button socket, the two ends symmetry offers shoulder hole on the described pedestal, bilateral symmetry is provided with the square groove that communicates with shoulder hole at the pedestal middle part, near the square groove bilateral symmetry sunk screw group is being installed, described locking steel ball is installed in the square groove, described pedestal right-hand member is equipped with spring block, left end offers guard timber push-button socket sliding tray, described spring and guard timber locking bar symmetry are installed in the shoulder hole, spring one end is installed on the spring block, the other end contacts with the guard timber locking bar by steel ball, described guard timber locking bar one end is equipped with the height guard timber locking bar pin identical with steel ball size, the other end is fixed on the guard timber push-button socket by holding screw, offer the arc separating tank near square groove place symmetry on the described guard timber locking bar, described guard timber push-button socket is U-shaped groove structure near the pedestal end, its end cooperates with pedestal and links to each other, described center fixed holder assembly closely links to each other with guard timber by the guard timber lock, described guard timber lock is U-shaped structure, the outside is cylindrical, and be provided with the horizontal fixed piece in the outside, be provided with the locking slot corresponding with locking steel ball in guard timber lock inboard.
Advantage of the present invention is:
Simple in structure, reasonable in design, can make shotgun in the process of using, reduce the shock loading that produces between gun barrel and the guard timber to greatest extent, accelerate the cooling velocity of gun barrel, and gun barrel can free vibration, be conducive to improve the accuracy at target of weapon, the while guard timber is connected more reliable with the rifle body, dismounting is more convenient, and is easy to use, low cost of manufacture is convenient to penetration and promotion.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
By Fig. 1-Fig. 6 as can be known, the present invention includes guard timber 1, last gun barrel 2, following gun barrel 3 and center fixed holder assembly, the described gun barrel 2 of going up links to each other by the center fixed holder assembly with following gun barrel 3, described center fixed holder assembly comprises pedestal 4, spring 5, steel ball 6, guard timber locking bar 7, sunk screw group 8, locking steel ball 9 and guard timber push-button socket 10, the two ends symmetry offers shoulder hole 11 on the described pedestal 4, be provided with the square groove 12 that communicates with shoulder hole 11 in pedestal 4 middle part bilateral symmetry, near square groove 12 bilateral symmetry sunk screw group 8 is being installed, described locking steel ball 9 is installed in the square groove 12, described pedestal 4 right-hand members are equipped with spring block 13, left end offers guard timber push-button socket sliding tray, described spring 5 and guard timber locking bar 7 symmetries are installed in the shoulder hole 11, spring 5 one ends are installed on the spring block 13, the other end contacts with guard timber locking bar 7 by steel ball 6, described guard timber locking bar 7 one ends are equipped with the height guard timber locking bar pin 14 identical with steel ball 6 diameters, the other end is fixed on the guard timber push-button socket 10 by holding screw 15, offer arc separating tank 16 near square groove 12 place's symmetries on the described guard timber locking bar 7, described guard timber push-button socket 10 is U-shaped groove structure near the pedestal end, its end cooperates with pedestal 4 and links to each other, described center fixed holder assembly closely links to each other with guard timber 1 by guard timber lock 17, described guard timber lock 17 is U-shaped structure, the outside is cylindrical, and be provided with horizontal fixed piece 18 in the outside, be provided with the locking slot 20 corresponding with locking steel ball 9 in guard timber lock 17 inboards.
Described guard timber 1 both sides offer the guard timber lock mounting groove 19 of cylinder.
Guard timber of the present invention and gun barrel are converted to released state by locking: promote guard timber push-button socket 10 to the right, guard timber locking bar 7 overcomes spring 5 active forces and moves right, meanwhile, locking steel ball 9 is the 4 centre movements along arc separating tank 16 to pedestal under the effect of outside pressure, finally slide into position as shown in Figure 3, lock steel ball 9 this moment and maintain an equal level with pedestal 4 outsides, pedestal 4 just can conveniently be pulled down from guard timber 1;
