Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further details.
See Fig. 1 ~ Fig. 7, gun stock fold mechanism of the present utility model, is comprised the gun stock body 1 and gun stock seat 4 that are hinged by gun stock axle 3, described gun stock body 1 is provided with buckle 2 and buckle spring 5, the two ends of buckle spring 5 are fixedly connected with gun stock body 1 with buckle 2 respectively, as shown in Figure 6; Described gun stock seat 4 is provided with the snap seats 6 that can lock with described buckle 2, as shown in figures 1 to 6, when gun stock is in deployed condition, described buckle 2 fastens with snap seats 6.
See Fig. 6 and Fig. 7, described buckle 2 is provided with the first snap ramp 21, and snap seats 6 is provided with the second snap ramp 61 locked with this first snap ramp 21; Described buckle 2 is also provided with guiding surface 22.The design of the first snap ramp 21 and the second snap ramp 61 eliminates the fastening gap between buckle 2 and snap seats 6, can not rock after making in shooting course.
See Fig. 1, when the folding gun stock seat 4 of needs is with gun stock body 1, releasing gun stock seat 4 is fastened and connected with gun stock body 1, gun stock seat 4 wire-wrap tool holder axle 3 is rotated 180 °, gun stock seat 4 and gun stock body 1 is folded.As shown in figs. 2 to 4, described gun stock body 1 is provided with the first helicoid 7, described gun stock seat 4 is provided with the second helicoid 8 can fitted with described first helicoid 7, described first helicoid 7 and the second helicoid 8 are arranged on the hinged place of gun stock body 1 and gun stock seat 4, when gun stock body 1 wire-wrap tool holder axle 3 rotates close to 180 °, described first helicoid 7 and the second helicoid 8 start to enter cooperation, when gun stock body 1 wire-wrap tool holder axle 3 rotates to 180 °, the first helicoid 7 and the second helicoid 8 enter fit-state.The helicoid central shaft of described first helicoid 7 and the second helicoid 8 is concentric with gun stock axle 3, and described first helicoid 7 and the second helicoid 8 are a pair coupling helicoid relative to gun stock axle 3.
See Fig. 4 and Fig. 5, gun stock axle 3 is provided with step surface 9, and on gun stock axle 3, cover has gun stock spring 10, and gun stock spring 10 is placed between step surface 9 and gun stock seat 4, and gun stock axle 3 is fixedly connected with gun stock body 1 by pin 11.Compensate for clearance 71 is left along the axis of its hinged gun stock axle 3 between described gun stock body 1 and gun stock seat 4, when gun stock is in folded state, under effect due to gun stock spring 10, the first helicoid 7 and the second helicoid 8 can be made to fit tightly, gun stock body 1 and gun stock seat 4 are fixedly positioning.
Elaborate below in conjunction with the use procedure of accompanying drawing to the utility model gun stock fold mechanism.
As shown in Figures 1 to 5, when gun stock is in deployed condition, buckle 2 and snap seats 6 fasten, gun stock body 1 is connected with gun stock seat 4, and because buckle 2 and the buckling parts of snap seats 6 are set to inclined-plane, eliminate and fasten gap, gun stock seat 4 and gun stock body 1 can not be rocked in shooting course.
When gun stock needs folding, pin the buckle 2 on gun stock body 1, compression buckle spring 5, until the first snap ramp 21 of buckle 2 departs from completely with the second snap ramp 61 of snap seats 6, thus gun stock seat 4 is separated with gun stock body 1; Pin buckle 2 not loosen, move gun stock body 1 and rotate relative to gun stock seat 4, after gun stock body 1 turns over certain angle, buckle 2 can be unclamped; When gun stock body 1 rotates to 180 ° relative to gun stock seat 4, under the cooperation of the first helicoid 7 and the second helicoid 8, now there is the sense that significantly puts in place, gun stock body 1 and gun stock seat 4 are fixedly positioning, realizes the folding location of gun stock body.
When gun stock is opened by needs, firmly move gun stock body 1 to rotate round about, after gun stock body 1 walks around certain angle, the first helicoid 7 on gun stock body 1 departs from the second helicoid 8 on gun stock seat 4, the sense that now puts in place disappears, and rotary resistance obviously reduces and evenly.Be rotated further gun stock seat 4, until the guiding surface 22 of buckle 2 contacts with snap seats 6, under the effect of guiding surface 22, when gun stock seat 4 rotates to 180 °, buckle 2 and snap seats 6 fasten, first snap ramp 21 of buckle 2 contacts completely with the second snap ramp 61 of snap seats 6, and gun stock is in deployed condition.
In sum, gun stock fold mechanism of the present utility model, when folding, only gun stock seat 4 can be separated with gun stock body 1 by the buckle 2 need pressed on gun stock body 1, move gun stock body 1 after gun stock seat 4 rotates 180 °, on the first helicoid 7 on gun stock body 1 and gun stock seat, second helicoid 8 of 4 is fitted, and has the sense that obviously puts in place, realize gun stock easily folding in this process; Expansion process does not need special mechanism to change, and directly moves gun stock body 1 and rotates in the opposite direction relative to gun stock seat 4, and after gun stock launches, under the effect of buckle spring 5, buckle 2 coordinates with snap seats 6 and fastens, and is connected by gun stock seat 4 with gun stock body 1.This gun stock fold mechanism structure is simple, easy to operate, achieves the reliable location after gun stock folded body and rapid deployment, meets instructions for use.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
