Description

Retractable spontoon

Technical field

The utility model belongs to the guard articles for use, especially a kind of retractable spontoon that the impact nail is arranged.

Background technology

Baton is the useful tool that the police checks an evil and suppresses the evil and pacifies the good, and the baton of market probably has two kinds now, and a kind of is electric billy, and a kind of is mechanical baton.Electric billy is a kind of baton that produces high-tension electricity, produces high, forceful electric power pressure during use, but easily the people is caused inevitable injury, can not use in some occasion; The machinery baton is easy to carry, can stretch, but its single function reduces its superiority in some occasion, such as difficult its effect of performance of baton in the occasion that punctures the glass at needs.So current mechanical baton except the advantage before having, also should have the characteristics that puncture hard thing.

The utility model content

At the shortcoming of prior art, the purpose of this utility model provides a kind of simple in structure, and is easy to carry, reliable and stable and can puncture the retractable spontoon of hard thing.

The utility model comprises outer tube, middle pipe and inner core; Outer tube, middle pipe and inner core are taper; It is characterized in that inner core one end is equipped with plug, the other end is equipped with and impacts nail, and inner core is divided into exocoel and inner chamber by step, and exocoel communicates with inner chamber; Exocoel has T type support column, and T type support column has eccentric projection, and T type support column is with first spring, and the first spring roof pressure is between T type support column and step; Inner chamber has the hammer and second spring, and hammer has blind hole; Eccentric projection penetrates inner chamber from exocoel and dynamically contacts with the blind hole of hammer, and hammer has the one side of blind hole to contact with step, hammer another side and second spring, one end in contact, and the second spring other end is supported in the inner chamber; T type support column top contacts with impacting the nail tail end, impacts the nail tip and protrudes outside the inner core.

The outer tube that the utility model is preferably implemented is with rotation set, and outer tube one end and sleeve one end screw, and the sleeve other end has rotation set, and the outer tube other end has the screw thread that cooperates with rotation set.

The outer tube that the utility model is preferably implemented is with the wrister ring, and the wrister ring has anti-skidding ripple.

The utility model screws rotation set at the end of outer tube near the impact nail when tackling the offender, and pipe and outer core are stretched the generation that checks an evil in can making during use; When the utility model need puncture hard thing, rotation set is screwed at the end of outer tube near plug, firmly compression shock is followed closely, the eccentric projection of interior in-core is constantly exerted pressure to second spring, slip into the blind hole of hammer when eccentric projection after, second spring releases energy, and makes to impact to follow closely to stab forward to hard thing, and hard thing is punctured.The utility model is safe and reliable, be convenient for carrying, cost is low and easy popularization, is applicable to that public security, People's Armed Police, guard attack when executing the task and broken weapon.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is described in more detail.

Referring to Fig. 1 to Fig. 3, the utility model comprises outer tube 1, middle pipe 2, inner core 3, sleeve 15 and rotation set 16; Outer tube 1, middle pipe 2 and inner core 3 are the taper of internal diameter convergent, and their two ends are all divided bigger diameter end and miner diameter end; The miner diameter end of inner core 3 is therefrom managed 2 bigger diameter end and is entered, the miner diameter end of pipe 2 during the bigger diameter end of internal diameter is slightly larger than; In pipe 2 miner diameter end enter from the bigger diameter end of outer tube 1, the bigger diameter end of middle pipe 2 is slightly larger than the miner diameter end of outer tube 1, on the pipe 2, outer tube 1 bigger diameter end was combined with sleeve 15 during outer tube 1 was enclosed within, pipe 2 and inner core 3 did not skid off the bigger diameter end of outer tube 1 during sleeve 15 made; Inner core 3 and middle pipe 2, middle pipe 2 and outer tube 1 are slidingly matched mutually; It is the sliding scale of inner core 3 that the miner diameter end of inner core 3 manages therefrom that taper external diameter that 2 miner diameter end begins to be protruding to inner core 3 finishes greater than middle pipe 2 miner diameter end internal diameters, and the taper external diameter of the miner diameter end of middle pipe 2 pipe 2 from the miner diameter end of outer tube 1 begins to be protruding to is the sliding scale of middle pipe 2 greater than the end of outer tube 1 miner diameter end internal diameter; Inner core 3 miner diameter ends are equipped with plug 4, bigger diameter end is equipped with and impacts nail 5, impacting nail 5 protrudes from sleeve 15, sleeve 15 internal and external threads cooperate with rotation set 16, rotation set 16 is the shape of a hoof nut of two helicitic textures, in outer tube 1 miner diameter end internal thread is arranged, and outer tube 1 can cooperate with rotation set 16, outer tube 1 is with the wrister ring, and the wrister ring has anti-skidding ripple.

Referring to Fig. 4 to Fig. 6, inner core 3 one ends are equipped with plug 4, and the other end is equipped with and impacts nail 5, and inner core 3 is divided into exocoel 7 and inner chamber 8 by step 6, and exocoel 7 and inner chamber 8 communicate; Exocoel 7 has T type support column 9, and T type support column 9 has eccentric projection 10, and the afterbody of eccentric projection 10 departs from the axis of T type support column 9 a little; T type support column 9 is with first spring, 11, the first spring roof pressures between T type support column 9 and step 6; Inner chamber 8 has the hammer 12 and second spring 13, and hammer 12 has blind hole 14, and the internal diameter of blind hole 14 is a bit larger tham the diameter of the eccentric projection 10 of T type support column 9; The bottom of hammer 12 and second spring, 13 1 end in contact, second spring, 13 other ends are supported on and make hammer 12 tops always press close to the spring ratio of step 6, the second springs 13 much larger than first spring 11 in the inner chamber 8; T type support column 9 one ends contact with impacting nail 5 tail ends, impact nail 5 most advanced and sophisticated protrusions outside inner core 3; When eccentric projection 10 stressed when exocoel 7 penetrates inner chamber can with the EDGE CONTACT of the blind hole 14 of hammer 12.

When tackling the offender, rotation set 16 is screwed at the end of outer tube 1 near impact nail 5, pipe 2 and inner core 3 are stretched and are formed a long baton (as Fig. 1 state) in can making during use, utilize inertia inner core 3 and middle pipe 2 can be regained after the use.When needing to puncture hard thing such as glass, rotation set 16 is screwed at the end (as Fig. 2 state) of outer tube 1 near plug 4, hold baton make impact nail 5 firmly roof pressure want broken glass, impact the eccentric projection 10 that promotes T type support column 9 in the nail 5 withdrawal batons and penetrate inner chamber from exocoel 7, eccentric projection 10 props up the edge promotion hammer 12 of the blind hole 14 of hammer 12 and draws back and constantly exert pressure to second spring 13 with very little contact area, along with the bounce of second spring 13 continues to increase, frictional force between the edge of eccentric projection 10 and blind hole 14 can not be kept the state that eccentric projection 10 props up the edge of blind hole 14 finally, eccentric projection 10 slips into the blind hole 14 of hammer 12, hammer 12 hits T type support column 9 at a high speed, second spring 13 releases energy by the nail hitting 5 that liquidates of hammer 12 and T type support column 9, impact nail 5 is stabbed forward to glass, glass crushing.

The utility model is safe and reliable, be convenient for carrying, cost is low and easy popularization, is applicable to that public security, People's Armed Police, guard attack when executing the task and broken weapon.
