Abstract
The utility model relates to a multifunctional detent latching fling stick with a changeable stick head, which is formed by sleeving three steel tubes with grooves. Holes are respectively drilled in suitable positions at the front ends and the rear ends of two adjacent steel tubes in the same direction, springs and detents are arranged in the detent holes at the rear end of a stick body, and the detents are pressed to withdraw the stick. When the stick is flung out, the detents respectively slide to the detent holes, and the detents prop up and are respectively clamped in the holes to be latched; the stick head and the stick body are in threaded connection with are separable, and the stick head comprises a columniform or spherical blunt head and a conical edgily head which has piercing capability to increase the sticking function.
Description
Affiliated technical field
The utility model relates to a kind of alert with hitting apparatus, and especially a kind of closedown structure is simple, and can make it have the rod that gets rid of of different lethality according to the requirement under the different situations.
Background technology
Present known mechanical latching gets rid of rod, and its closedown structure is to be combined with a protruding ring by ball, and ball is stuck in the groove of rod body inwall, realizes mechanical latching.Its structure more complicated.The present rod rod head that gets rid of all is fix cylindrical or spherical, hits function singleness, can not satisfy various demands in emergency circumstances.
Summary of the invention
In order to overcome the problem that the existing machinery locking is got rid of rod closedown structure complexity and hit function singleness, the utility model provides a kind of mechanical latching to get rid of rod, not only closedown structure is simple, and by using difform rod head, can make it except that having the strike function of generally getting rid of rod, the function that can also have puncture has strengthened its strike power greatly.
The technical scheme in the invention for solving the technical problem is: three steel pipes that can be nested together, there is the twice longitudinal fluting in the outside of every steel pipe, the groove of the thinnest first segment outer wall of steel pipe can just stick into the lug boss of the inwall of the second joint steel pipe, the outer wall groove of the second joint steel pipe can just stick into the lug boss of the 3rd steel pipe inwall, three steel pipe sockets can be slided together vertically but can not rotate vertically.At the rear end of first steel pipe and the front end of second steel pipe, and second joint steel pipe rear end and the 3rd joint steel pipe front end appropriate location, boring respectively on same direction, hole clipping on second joint and the 3rd joint steel pipe front end is slightly less than the pin hole of the first segment and the second joint steel pipe rear end, in the pin hole of the first segment and the second joint steel pipe rear end, put spring and bayonet lock respectively, bayonet lock be shaped as up-small and down-big multidiameter, the bayonet lock top is taper, and the bayonet lock thin segment can pass the hole clipping of second joint and the 3rd joint steel pipe front end.When the steel pipe that is nested together is thrown out of, when bayonet lock slided to the hole clipping place of second joint and the 3rd joint steel pipe front end, the bayonet lock ejection sticked in the hole clipping, and rod is just by locked.Depressing bayonet lock can regain rod.The closedown structure that the 3rd joint and second saves between steel pipe is identical with the closedown structure that first and second saves between steel pipe.When depressing the bayonet lock of the 3rd joint on the steel pipe, the second joint steel pipe is just recoverable, and when the bayonet lock place of receiving to the second joint steel pipe, the tube wall of the 3rd joint steel pipe utilizes the tapering on bayonet lock top that bayonet lock is depressed, and first segment is promptly recoverable, finishes release and receives the rod action.Connect a screw rod at the front end of first segment steel pipe, the rod tail also connects a screw rod.The cylindricality of screwing on the screw rod on top or spherical rod head can become the general common rod that gets rid of.Unload cylindrical rod head, the sharp taper rod head of screwing on gets rid of rod and has just had the puncture function, thereby can strengthen the strike power of getting rid of rod greatly.
The beneficial effects of the utility model are: mechanical latching is simple in structure, increases the function of getting rid of rod, can satisfy under the different situations getting rid of the different requirements of hitting power of rod.

The specific embodiment
In Fig. 1, first segment rod body (1) is inserted in the endoporus of Two-section rod body (2), and Two-section rod body (2) is inserted in the endoporus of cudgel of three linked sections body (3).
In embodiment illustrated in fig. 2, spring (5) and bayonet lock (4) place the pin hole of first segment rod body (1), and the upper end of bayonet lock (4) snaps in the hole clipping of Two-section rod body (2) front end, and rod promptly by locked, is finished locking.
In the embodiment shown in fig. 3, when cudgel of three linked sections body (3) is received bayonet lock place to Two-section rod body (2), the tube wall of cudgel of three linked sections body (3) utilizes the taper surface on bayonet lock (4) top that bayonet lock (4) is depressed, hole wall on the Two-section rod body (2) also utilizes the conical surface that bayonet lock (4) is continued to press down again, can finish release.
In the embodiment shown in fig. 4, rod head connecting screw rod (6) one ends insert in the stomidium of first segment rod body (1), fix with welding or riveted way, and the rod head is connected by rod head connecting screw rod (6) threadably with the rod body.
The part drawing of Fig. 5 to Figure 10 has only showed the shape and the structure of part.The outside dimension of first segment rod body (1) and Two-section rod body (2) should equal the internal diameter size of Two-section rod body (2) and cudgel of three linked sections body (3), matched in clearance respectively.Two-section rod body (2) is than long 2 centimetres approximately of first segment rod bodies (1), and cudgel of three linked sections body (3) is than long 1 centimetre approximately of Two-section rod body (2).The screw thread of rod head connecting screw rod (6) is identical with screw thread on the rod tail attaching parts (9).The step length of bayonet lock (4) and height of conical surface equal rod body thickness of steel pipe.
