Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, firearms connect with steel ball rotational lock mechanism, including connection seat 1 in a tubular form, connect suit gun barrel in seat 1 endoporus；Described connection seat 1 rear portion is provided with the first ladder cylindrical 11 and the second ladder cylindrical 12, and the diameter of described first ladder cylindrical 11 is more than described second ladder cylindrical 12.
The second ladder cylindrical 12 on described connection seat, circumferentially arranged with annular groove 121, arranges collar 6 in order to spacing to lock sleeve 2 in this annular groove 121；The second ladder cylindrical 12 on described connection seat is radially provided with multiple steel ball installing hole 122, the circumferencial direction of the steel ball installing hole 122 second ladder cylindrical 12 along described connection seat is uniformly distributed, and is provided with a rotating steel ball 3 in each steel ball installing hole 122.In the present embodiment, steel ball installing hole 122 is provided with three.
Sheathed rotating lock sleeve 2 on first ladder cylindrical the 11, second ladder cylindrical 12 on described connection seat, described lock sleeve 2 is positioned at the rear of collar 6.The front end of described lock sleeve 2 is provided with the counterbore of the first ladder cylindrical 11 on accommodating described connection seat.Being provided with a Blind locating holes 22 on the sidewall of lock sleeve 2 vertically, be provided with positioning head 4 in this Blind locating holes 22, sheathed back stop 5 on positioning head 4, back stop 5 is compression spring.Described positioning head 4 is in cylinder, and positioning head 4 two ends diameter is respectively less than the diameter of interlude.
The first ladder cylindrical 11 on described connection seat is along the circumferential direction provided with an arc deep gouge, being provided with multiple spacing hole 111 for spacing described positioning head 4 on this arc deep gouge vertically, the circumferencial direction of the described spacing hole 111 first ladder cylindrical 11 along described connection seat is uniformly distributed.
Described lock sleeve 2 be provided with straight knurling vertically, during rotary locking cover can increasing friction force, easy disassembly deafener.The inner peripheral surface front portion of described lock sleeve 2 is made up of multiple identical arc surfaces 21, and the radius of described arc surface 21 is gradually increased clockwise.Described lock sleeve inner chamber arc surface 21 front portion is circular hole, and the radius of this circular hole is less than the least radius of described arc surface 21, it is to avoid steel ball 3 comes off.On described lock sleeve, the quantity of arc surface 21 is equal with the quantity of described steel ball is three.Described steel ball 3 contacts with the arc surface 21 of described lock sleeve.
As shown in Figure 7, when using this steel ball rotational lock mechanism's assembling deafener 8, deafener 8 interference fit anterior with the connection seat 1 in steel ball rotational lock mechanism connects as one, deafener is enclosed within the oral area of gun barrel 7, rotate counterclockwise lock sleeve 2, making arc surface 21 that the steel ball 3 on connection seat 1 compresses on lock sleeve, steel ball 3 conflict with the limited ring groove 71 on gun barrel 7, positioning head 4 withstands lock sleeve upper limit hole 111 thus locks gun barrel 7 simultaneously, deafener installation.When needing to dismantle deafener, turn clockwise lock sleeve 2, and steel ball 3 departs from the limited ring groove on gun barrel makes gun barrel 7 unlock, deafener of dismantling.
Skilled person will appreciate that, it is possible to use this steel ball rotational lock mechanism connects the parts that other needs are frequently dismantled with firearms.
