Abstract
The utility model provides a kind of adjustable telescopic bar, including outer tube, inner sleeve, spring, fixing piece and closed plate, the outer tube and inner sleeve are hollow cylindrical shape, and in inner sleeve is wrapped in by outer tube, inner sleeve slides in outer tube, and for the spring between outer tube and inner sleeve, the closed plate is located at outer tube and inner sleeve one end.The utility model enables adjusting rod automatically to stretch out, and structure is simple, and use is more convenient, and safety is preferable, is convenient for marketing and application.
Description
Technical field
The utility model belongs to Laboratory Instruments apparatus field more particularly to a kind of adjustable telescopic bar.
Background technique
Telescopic rod is relatively common in we usually live, and also wider model, existing telescopic rod are most of all for its purposes
Be using be between tubule and big pipe using interference fit, telescopic rod elongation after by it is this cooperation be unlikely to retract to fix,
Or tubule and big pipe are used and are threadedly engaged.But that there is telescopic effects is undesirable for existing telescopic device, safety is not
High problem.
Therefore, a kind of adjustable telescopic bar is invented to be very necessary.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of adjustable telescopic bar, to solve existing telescopic device
It is undesirable that there is telescopic effects, is not easy to be dismantled, the not high problem of safety.
A kind of adjustable telescopic bar, including outer tube, inner sleeve, spring, fixing piece and closed plate, the outer tube and inner sleeve
Pipe is hollow cylindrical shape, and in inner sleeve is wrapped in by outer tube, inner sleeve slides in outer tube, and the spring is located at
Between outer tube and inner sleeve, the closed plate is located at outer tube and inner sleeve one end.
A kind of adjustable telescopic bar, the fixing piece include that hook and fixed column, the hook are mounted on the inner sleeve
End, the fixed column are fixed on the end of the outer tube.
A kind of adjustable telescopic bar, the radially mutually socket arrangement of several outer tube, inner sleeves, i.e. several differences
The outer tube and inner sleeve of diameter are mutually socketed.
Compared with prior art, the utility model has the following beneficial effects:
The setting of the utility model spring, enables adjusting rod automatically to stretch out, and structure is simple, and use is more convenient.
The setting of the fixing piece of the utility model is conducive to improve safety, and applicability is preferable.
The setting of the closed plate of the utility model is convenient for dismantling, and it is safe to have ensured that it is used.
Detailed description of the invention
Fig. 1 is the opening state structural schematic diagram of the utility model.
Fig. 2 is the closed state structural schematic diagram of the utility model.
Fig. 3 is the schematic diagram of closed state of the utility model.
In figure:
1- outer tube, 2- spring, 3- fixing piece, 31- hook, 32- fixed column, 4- closed plate, 5- inner sleeve.
Specific embodiment
The utility model is described further below in conjunction with attached drawing:
Embodiment:
As shown in attached drawing 1 to attached drawing 3
The utility model provides a kind of adjustable telescopic bar, including outer tube 1, spring 2, fixing piece 3, closed plate 4 and inner sleeve
Pipe 5, outer tube 1 and inner sleeve 5 are hollow cylindrical shape, and in inner sleeve 5 is wrapped in by outer tube 1, spring 2 is located at housing
Between pipe 1 and inner sleeve 5, effect is can to skid off inner sleeve 5 outward along outer tube 1；Closed plate 4 is by outer tube 1 and interior
Casing 5 is closed at one end, and the diameter of closed plate is slightly larger than the outer diameter of inner sleeve 5, therefore the step formed can tangle the platform of outer tube 1
Rank, to prevent inner sleeve 5 from deviating from outer tube 1；Fixing piece 3 includes hook 31 and fixed column 32, and hook 31 is mounted on inner sleeve 5
One end, hook 31 can rotate around fixing end, hook fixed column 32 to link up with 31, fixed column 32 is then fixed on outer tube
1 one end；Several outer tubes 1 and the mutually socket of inner sleeve 5 are got up, and can form one can extend outwardly into a fixed length
The telescopic rod of degree.
In the utility model, when need to use, hook 31 is opened, the automatic spring under the effect of spring 2 of inner sleeve 5 is received
Inner sleeve 5 is pressed into outer tube 1, hook 31 is successively hooked fixed column 32 by Hui Shi.
The opening in technical solutions of the utility model using technical solution described in the utility model or those skilled in the art
It gives, designs similar technical solution, and reach above-mentioned technical effect, be to fall into the protection scope of the utility model.
