Abstract

A firearm (10) having a stock (11), a receiver (14) and interconnectable mount block (23) with the block having spaced apart recesses (33, 34) and receiver spaced apart foot projections (47, 48) configured to fit into and be locked in such block recesses.

Description

The receiver of rifle and fixture

Existing rifle comprises receiver, this receiver is fixed by recoil block and the part of the connector by on this block and receiver, to be used for receiver and the joint of block and for dismounting receiver to be separated (seeing Ruger44 type carbine) from block.In addition, also proposed receiver recoil plate, this recoil plate is transmitted to power on the receiver and (sees U.S. Patent number: 2,108,648 and 2,844,904) when being used to be absorbed in shooting and recoil.But, firmly accurately be fixed on the gun stock for rear portion, and can also do not have a kind of structure can satisfy this requirement fully without the viewpoint of the fast quick-detach of instrument with receiver.

Put it briefly, the present invention includes a receiver fixed stop, this block is fixed on the gun stock of rifle, to be used for removably fixed cover cylinder base.This block comprises the groove that is provided with at interval, to be used to be installed in the bottom projection at receiver rear portion.This block also has the vertical wall that is abutted against mutually with receiver, is used for conductance.This block can comprise front boss and rear boss.

A feature of the present invention is when block and receiver are fixed together, and they are bonded with each other at three (3) surface locations and basic at interval two (2) positions for block and receiver width.

Fig. 1 is the right side elevation view of the present invention's rifle (the part gun barrel is not illustrated);

Fig. 2 is the partial sectional view of the amplification of recoil block, set bolt and the receiver installed;

Fig. 3 is the view along the hatching 3-3 of Fig. 2;

Fig. 4 is the view along the hatching 4-4 of Fig. 3;

Fig. 5 is the exploded view of block and receiver rear end.

In Fig. 1 and 2, rifle 10 comprises gun stock 11, gun barrel 12, receiver 14, cartridge clip 16, trigger 17 and trigger backplate 18.Receiver 14 comprises behind the holistic optics foresight (not shown) before the accurate tool holder 21a and.

Molded composite gun stock 11 comprises a gun stock groove 22, is used to assemble the fixed stop 23 and pieceable receiver 14 (see figure 3)s of receiver.Gun stock groove 22 has a rear wall 22a.Block 23 device 25 that is fixed is fixed, and this fixture 25 comprises threaded shank 26 and smooth pad 27w, and wherein bolt 26 is in nuts 26h is located in molded passage 19, and packing ring 27 is arranged in the gun stock groove 20 of butt joint.

Referring to Fig. 3-5, receiver fixed stop 23 comprises flat front surface 30, and a surf zone 30u is arranged on the top on this surface 30, and this regional width is A.Block 23 has vertical side 23a, 23b, and the two sides interval width is B.Block 23 also has a rear surface 28.Rear portion block boss 28a stretches out from rear surface 28, and wherein also comprises a screwed hole 31, and this screwed hole is used to install threaded shank 26.Surface 28 abuts against on the groove walls 22a of gun stock.Block 23 also comprises an anterior boss 30a, is used for settling and supporting hammer pole 60 and hammer spring 62 (Fig. 4).Block 23 has bottom prolongation 32.

Block 23 has the connector receiver groove 33,34 and the front surface area 30u of two (2) identical left surface and right flank, and they match with receiver 14 and are connected to form between block 23 and receiver 14.Only show the receiver groove 33 of right flank among Fig. 4, in Fig. 5, then show groove 33,34.Receiver groove 33 has upper face 38a, and it is made up of upper channel part 39a and upper lock certain portions 40a.Receiver groove 33 also has the channel surface 42a and the vertical surface 43a of lower knuckle.Similarly, groove 34 has upper face 38b (not shown), and this surface 38b has upper channel part 39b (not shown) and upper lock certain portions 40b.Groove 34 also has the channel surface 42b and the vertical surface 43b of a bottom bending.

Refer now to receiver 14, especially its rear end 14e shows two the separated bottom of bending projections 47,48.But also show upper sleeve seat abutment wall 51, be used for upper surface area 30u with the ccontaining block front surface 30 of mode that engages.

Bottom projection 47 has surperficial 53a and bottom convexly curved surperficial 54a, front surface 56a and the rear surface 57a that tilts.Projection 48 also has a surperficial 53b who tilts, the surperficial 54b that the bottom is convexly curved, front surface 56b and rear surface 57b.The width B of receiver is identical with the width B of block 23.

In the assembling process that block 23 in making receiver 14 and being fixed in gun stock groove 22 engages, receiver 14 is tilted, as shown in Figure 2, so that the

bottom projection

47,48 of receiver enters the receiver groove 33,34 of block.When

projection

47,48 had just entered, receiver 14 just clockwise rotated, as shown in Figure 2, and up to the latched position that arrives Fig. 4.When locking:

1) stop-surface 40a, the surperficial 53a of 40b and receiver, 53b engagement;

2) stop-surface 42a, the surperficial 54a of 42b and receiver, 54b is meshed; With

3) upper front surface of block zone 30u engages with the area supported 51 of receiver.
