Abstract
The utility model discloses a swimming lifesaving rod with elastic stretching-retracting functions, which belongs to the technical field of swimming lifesaving apparatuses and aims at solving the problems that the length of the existing swimming lifesaving rod is difficult to adjust due to restriction in structure and adverse effects are brought for lifesaving. Multiple inner sleeves are arranged coaxially in sequence, an outer sleeve is arranged between every two adjacent inner sleeves, the two adjacent ends of every two adjacent inner sleeves are arranged in the same outer sleeve and are connected through an extension spring, and a gap is formed between the outer side wall of each inner sleeve and the inner side wall of the corresponding outer sleeve; a rod-shaped handle is fixed on the outer end of the inner sleeve, at one outermost end, in the multiple inner sleeves; a ring-shaped handle is fixed on the outer end of the inner sleeve, at the other outermost end, in the multiple inner sleeves. The swimming lifesaving rod is used for lifesaving in swimming places.
Description
Technical field
The utility model relates to a kind of life-saving pole for swimming, belongs to swimming lifesaving equipment technical field.
Background technology
Along with improving constantly of living standards of the people, the people that participate in swimming exercise are more and more, and swimming place is also in continuous increase.In order to ensure vast swimming fan's life security, swimming place must be equipped with buoyant apparatus.At present, conventional swimming lifesaving equipment can be saved and gives birth to circle, lifesaving toss, lifeline, life saving rod etc.And the length of the life saving rod using is at present subject to structural limitations, adjust trouble, bring adverse effect to lifesaving.
Utility model content
The purpose of this utility model is to provide a kind of life-saving pole for swimming with elastic telescopic function, is subject to structural limitations with the length that solves existing life-saving pole for swimming, adjusts trouble, brings the problem of adverse effect to lifesaving.
The utility model addresses the above problem takes following technical scheme:
A kind of life-saving pole for swimming with elastic telescopic function of the present utility model, it comprises many outer tubes and many inner sleeves, described in there is elastic telescopic function life-saving pole for swimming also comprise shaft-like handle, ring-shaped handle and multiple coil tension spring; Described many inner sleeves coaxially arrange successively, between adjacent two inner sleeves, an outer tube is set, and two abutting ends of adjacent two inner sleeves are arranged in same inner sleeve, between two abutting ends of described adjacent two inner sleeves, connect by a coil tension spring, between inner sleeve lateral wall and outer tube madial wall, be provided with gap, the outer end that is positioned at the inner sleeve of one end head in described many inner sleeves is fixed with shaft-like handle, and the outer end that is positioned at the inner sleeve of other end head in many inner sleeves is fixed with ring-shaped handle.
The utility model beneficial effect is compared with prior art: the utility model is simple in structure, use is safe, reliable, and there is elastic telescopic function, in lifesaving process, can play the effect of buffering, use life saving rod of the present utility model can shorten the lifesaving time.
Brief description of the drawings
Fig. 1 is the main cutaway view of integral structure of the present utility model.
Detailed description of the invention
Below in conjunction with concrete brief description of the drawings book detailed description of the invention of the present utility model.
Detailed description of the invention one: in conjunction with Fig. 1 explanation, a kind of life-saving pole for swimming with elastic telescopic function of present embodiment, it comprises many outer tubes 1 and many inner sleeves 2, described in there is elastic telescopic function life-saving pole for swimming also comprise shaft-like handle 3, ring-shaped handle 4 and multiple coil tension spring 5; Described many inner sleeves 2 coaxially arrange successively, between adjacent two inner sleeves 2, an outer tube 1 is set, and two abutting ends of adjacent two inner sleeves 2 are arranged in same inner sleeve 2, between two abutting ends of described adjacent two inner sleeves 2, connect by a coil tension spring 5, between inner sleeve 2 lateral walls and outer tube 1 madial wall, be provided with gap, the outer end that is positioned at the inner sleeve 2 of one end head in described many inner sleeves 2 is fixed with shaft-like handle 3, and the outer end that is positioned at the inner sleeve 2 of other end head in many inner sleeves 2 is fixed with ring-shaped handle 4.In addition, ring-shaped handle 4 is preferably annulus, and the inner ring diameter of annulus is advisable can be inserted in human body, can be inserted in annulus like this by lifesaving personnel health, and two handgrips are held annulus, thereby more failure-free improves the reliability of being sued and laboured by lifesaving personnel.The quantity of outer tube 1 and inner sleeve 2 is set as required.
Detailed description of the invention two: in conjunction with Fig. 1 explanation, the outside face of ring-shaped handle 4 is provided with fluorescence coating described in present embodiment.So arrange, can make ring-shaped handle 4 more eye-catching in water, be convenient to be grasped by lifesaver.In present embodiment, undocumented technical characterictic is identical with detailed description of the invention one.
Detailed description of the invention three: in conjunction with Fig. 1 explanation, described in present embodiment, the neighboring of two of adjacent two inner sleeves 2 abutting ends is respectively equipped with an annular boss 2-1, between the annular boss 2-1 of two abutting ends of adjacent two inner sleeves 2, connects by a described coil tension spring 5; The two ends of every outer tube 1 are fixed with annular catch 6, and outer tube 1, inner sleeve 2, annular catch 6 and annular boss 2-1 coaxially arrange, inner sleeve 2 and annular catch 6 endoporus bearing fits.So arrange, by annular catch 6 and annular boss 2-1 are set, can prevent that inner sleeve 2 from deviating from outer tube 1.In present embodiment, undocumented technical characterictic is identical with detailed description of the invention one or two.
Detailed description of the invention four: in conjunction with Fig. 1 explanation, on shaft-like handle 3, fixed cover is equipped with antiskid glue sleeve 7 described in present embodiment.So arrange, be beneficial to lifesaving personnel and grip shaft-like handle 3.In present embodiment, undocumented technical characterictic is identical with detailed description of the invention one.
When use, lifesaving personnel hold shaft-like handle 3, are caught ring-shaped handle 4 by lifesaving personnel hand, or health is inserted in ring-shaped handle 4, and two hold ring-shaped handle 4.
