Abstract
A retractable life-saving pole for swimming relates to a life-saving pole for swimming and aims to solve the following problems: for an existing retractable life-saving pole for swimming, an inner loop bar and an outer loop bar are fixed together through the screwing of internal and external thread bushings, in case of a life-saving emergency, the two thread bushings have to be loosened first to elongate the length of the two loop bars, the use is troublesome, and the life-saving time is delayed. An outer sleeve is fixedly connected with an annular plate, one end of an inner sleeve is arranged inside the outer sleeve and the other end of the inner sleeve passes through and exposes outside the outer sleeve, an outer boss is arranged on the external side wall at one end of the inner sleeve which is arranged inside the outer sleeve, the inner sleeve is axially limited through the annular plate and the boss, a step-shaped shaft head is fixed at one end of the inner sleeve which is arranged inside the outer sleeve, an eccentric limiting disc is fixedly sleeved on the step-shaped shaft head, the inner sleeve is contact with the internal side wall of the outer sleeve through the eccentric limiting disc to limit the rotation of the inner sleeve , and the inner sleeve and the outer sleeve are plugged through a first plug and a second plug.
Description
Technical field
The utility model relates to a kind of swimming lifesaving bar.
Background technology
Existing telescoping swimming lifesaving bar, after inside and outside loop bar is sleeved on together, outer cover in the junction is provided with an external thread sleeve, part in the lower end of external thread sleeve is attached on the loop bar wall has axially open, the lower end that also is external thread sleeve has the function of elasticity spreading, make inside and outside loop bar by spinning that internal and external screw thread overlaps, inside and outside loop bar is fixed together.When running into the lifesaving emergency situation, need unclamp two screw collars earlier, the length of two loop bars can be elongated, use cumbersomely, prolonged the lifesaving time.
The utility model content
The purpose of this utility model provides a kind of telescopic swimming lifesaving bar, to solve existing telescoping swimming lifesaving bar, after inside and outside loop bar is sleeved on together, outer cover in the junction is provided with an external thread sleeve, because the lower end of external thread sleeve has the function of elasticity spreading, make inside and outside loop bar by spinning that internal and external screw thread overlaps, inside and outside loop bar is fixed together.When running into the lifesaving emergency situation, need unclamp two screw collars earlier, the length of two loop bars can be elongated, use cumbersome, the problem that has prolonged the lifesaving time.
Described purpose is achieved by the following scheme:
A kind of telescopic swimming lifesaving bar of the present utility model, described swimming lifesaving bar comprises inner sleeve and outer tube, one end of described outer tube is captiveed joint with annular slab, one end of described inner sleeve is arranged in the outer tube, the other end of described inner sleeve passes the expose outside outside of sleeve pipe of outer tube and annular slab, be arranged on the end lateral wall of the inner sleeve in the outer tube and have outer lug boss, described inner sleeve is by annular slab and outer lug boss axial limiting, an end that is arranged on the inner sleeve in the outer tube is fixed with the notch cuttype spindle nose, fixed cover is provided with eccentric position-arresting disk on the described notch cuttype spindle nose, described inner sleeve contacts with the madial wall of outer tube by eccentric position-arresting disk and realizes that rotation-prevention is spacing, the other end of described outer tube is by the first plug shutoff, and the other end of described inner sleeve is by the second plug shutoff.
Be fixed with engaging lug on the other end lateral wall of described inner sleeve, hold the ring ring and be hung on the engaging lug.
Has skid resistant course on the other end lateral wall of described inner sleeve.
Effect of the present utility model: the utlity model has simple in structurely, safe in utilization, convenient, have flexible and spacing characteristics fast, use lifesaving bar of the present utility model can shorten the lifesaving time.
During use, when eccentric position-arresting disk is in non-spacing state, when only needing the pulling inner sleeve, rotate inner sleeve or outer tube again,, can use after making inner sleeve and outer tube fixing by eccentric position-arresting disk rotary spacing to enough length.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model.
Wherein, inner sleeve 1, outer tube 2, annular slab 3, outer lug boss 4, notch cuttype spindle nose 5, eccentric position-arresting disk 6, first plug 7, second plug 8, skid resistant course 9, engaging lug 10, hold the ring 11.
The specific embodiment
The specific embodiment one: as depicted in figs. 1 and 2, a kind of telescopic swimming lifesaving bar, described swimming lifesaving bar comprises inner sleeve 1 and outer tube 2, one end of described outer tube 2 is captiveed joint with annular slab 3, one end of described inner sleeve 1 is arranged in the outer tube 2, the other end of described inner sleeve 1 passes the expose outside outside of sleeve pipe 2 of outer tube 2 and annular slab 3, be arranged on the end lateral wall of the inner sleeve 1 in the outer tube 2 and have outer lug boss 4, described inner sleeve 1 is by annular slab 3 and outer lug boss 4 axial limitings, an end that is arranged on the inner sleeve 1 in the outer tube 2 is fixed with notch cuttype spindle nose 5, fixed cover is provided with eccentric position-arresting disk 6 on the described notch cuttype spindle nose 5, described inner sleeve 1 contacts with the madial wall of outer tube 2 by eccentric position-arresting disk 6 and realizes that rotation-prevention is spacing, the other end of described outer tube 2 is by 7 shutoff of first plug, and the other end of described inner sleeve 1 is by 8 shutoff of second plug.
The specific embodiment two: as illustrated in figs. 1 and 2, be fixed with engaging lug 10 on the other end lateral wall of the specific embodiment one described inner sleeve 1, hold ring 11 rings and be hung on the engaging lug 10.Design like this can make the people who needs lifesaving more can easily catch and hold ring 11.Engaging lug 10 and the quantity of holding ring 11 are complementary, holds ring 11 and can be a pair ofly also can be two pairs, and with respect to the uniform setting of the lateral wall of inner sleeve 1.
The specific embodiment three: as depicted in figs. 1 and 2, have skid resistant course 9 on the other end lateral wall of the specific embodiment one described inner sleeve 1.Design can make the people who needs lifesaving catch the swimming lifesaving bar more easily like this.
The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily and replacement all should be encompassed within the protection domain of the present utility model.
