Abstract

The utility model relates to a stepless telescopic baton of which the length can be randomly adjusted, and belongs to the technical field of security and explosion protection devices. The stepless telescopic baton comprises a base tube and a telescopic rod and is characterized in that the telescopic rod is sleeved in the base tube, the rear end thereof is connected with an eccentric locking mechanism matched with the base tube, and the front end thereof is connected with the end of the baton. The base tube is enwrapped with an adhesive plastic composite layer; and anti-slip grains are arranged on the adhesive plastic composite layer. The utility model has the advantages that firstly, the eccentric locking mechanism can be locked and unlocked at any places, and the baton can be adjusted in length in a stepless manner within a certain scope and locked through being screwed, so that the extension and retraction are flexible, and the use is convenient; secondly, the stepless telescopic baton has simple structure, reliable use, high structural strength, large impact force and less possibility of deformation; and thirdly, the end of the baton adopts a tubular spring structure, and the impact force can be effectively controlled, thereby better achieving the purpose of using the baton.

Description

A kind of stepless retractable spontoon

Technical field

The utility model relates to a kind of length adjustable stepless retractable spontoon arbitrarily, belongs to public security, antiriot equipment technical field.

Background technology

Baton is a kind of anti-riot utensil that public security is safeguarded that is used for, and existing retractable spontoon is named again and gets rid of rod or the hard whip of three joints, be matrix how with the stainless steel, also useful engineering plastics are that matrix processes, and this type of baton mostly is elastic construction, no axial locking device, use and to impact mode single, spread length is between 500mm～580mm, and it is shorter effectively to impact distance, and more piece fine texture gradually, stressed yielding, impact force is little.

Summary of the invention

Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and provides a kind of distance that impacts adjustable arbitrarily, reliable lock, and function is strong, stepless retractable spontoon easy to use.

The utility model is to address the above problem the technical scheme that is adopted to be: include parent tube and expansion link, it is characterized in that described expansion link is sleeved in the parent tube, the expansion link rear end connects the Camlock mechanism with the parent tube phase configuration, and the front end of expansion link connects the baton termination.

Press such scheme, described parent tube coats glue outward and moulds composite bed, and glue moulds that the holding area is provided with anti-skidding line on the composite bed.

Press such scheme, described Camlock mechanism comprises the eccentric lock shaft that links with the expansion link rear end, and sliding lock set is installed at the two ends of eccentric lock shaft, eccentric lock shaft middle part and eccentric lock tube phase configuration; Described eccentric lock puts offers circumferential stopper slot, circumferential stopper slot and the finger phase configuration that links with eccentric lock shaft.

Press such scheme, described baton termination is elasticity baton termination, is made of small casing, rubber sleeve and the pogo barrel that is sleeved on the rubber sleeve endoporus.

Press such scheme, be installed on guide pin bushing with the expansion link phase configuration at parent tube endoporus front end.

Use of the present utility model is: when Camlock mechanism is in when getting loose state, expansion link parent tube relatively is flexible arbitrarily, after the baton collapsing length puts in place, the relative parent tube of expansion link is rotated in the forward certain angle,, can realizes the locking of expansion link by the effect of Camlock mechanism; When unclamping, make Camlock mechanism unclamp the relative parent tube reverse rotation of expansion link certain angle and get final product that this moment, expansion link can carry out flexible arbitrarily; Be retractable to any position, can lock once more, expansion link can be retracted to the locking of the shortest position at ordinary times.

The beneficial effects of the utility model are: 1,, thereby realized within the specific limits stepless adjustable of baton length because Camlock mechanism can locate locking at an arbitrary position and unclamp, and promptly soon tight, capable of expansion and contraction, easy to use; 2, structure is provided with simply, and serviceability is reliable, the structural strength height of baton, and impact force is big, and is not yielding; 3, the pipe spring structure is adopted in the baton termination, can effectively control the dynamics of wounding, the better purpose that realizes using baton.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Include parent tube 3 and expansion link 6, end socket 1 is installed in the rear end of parent tube, and parent tube coats glue outward and moulds composite bed 2, and glue is moulded concavo-convex anti-skidding line is set on the composite bed, is convenient to gripping and anti-skidding; Described expansion link is a seamless tubular goods, be sleeved in the parent tube, the expansion link rear end connects Camlock mechanism by rivet 11, by Camlock mechanism and parent tube phase configuration, described Camlock mechanism comprises the eccentric lock shaft 12 of riveting mutually with the expansion link rear end, the middle part of eccentric lock shaft is bent axle (eccentric shaft), sliding lock set 13 is installed at the two ends of eccentric lock shaft, it is bearing in the parent tube, sliding lock set passes through circlip 17 axial location of eccentric lock axle head head, the bent axle and eccentric lock tube 16 phase configuration at eccentric lock shaft middle part; Described eccentric lock puts offers circumferential stopper slot 14, circumferential stopper slot and finger 15 phase configuration of radially installing, the other end of finger connects firmly mutually with eccentric lock shaft, because finger and the circumferentially effect of stopper slot, the expansion link reverse rotation does not have a few and can not lock yet, retractable is locked once more to any position; For strengthening the coupling mechanism force of Camlock mechanism, can groove be set in the periphery of sliding lock set and eccentric lock tube, with the frictional force of increase with the parent tube tube wall.Be installed on guide pin bushing 5 with the expansion link phase configuration at parent tube endoporus front end, described guide pin bushing is the nylon guide pin bushing, and parent tube front end and expansion link are better disposed, and can protect the expansion link surface not by sliding injury.Front end at expansion link 6 connects the baton termination, described baton termination is elasticity baton termination, comprise the rubber sleeve 9 and the small casing 8 that connect firmly mutually with the expansion link front end, small casing is sleeved in the rubber sleeve, be installed on plug 10 at rubber sleeve endoporus front end, between plug and small casing, be installed on pogo barrel 7, pogo barrel one end and small casing welding, small casing welds mutually with expansion link, constitutes elasticity baton termination thus.

Parent tube specification in the present embodiment: φ 22mm (external diameter) * 1mm (monolateral wall thickness) * 322mm (length); Expansion link (pipe) specification: φ 16mm (external diameter) * 1.5mm (monolateral wall thickness) * 300mm (length); Baton termination: length 160mm, external diameter φ 30mm; Whole baton: spread length 750mm, shorten length 500mm.
