Abstract
The utility model discloses a locking device for a telescopic rod pipe. The utility model comprises a locking mechanism. The utility model is characterized in that the locking mechanism is composed of a connecting rod, a clamping ring, a seat ring, a lower expanding ring, a drum-shaped ring, an upper expanding ring and a guiding ring, wherein the head end of the connecting rod is provided with outer screw threads which orderly penetrate through the seat ring, the lower expanding ring, the drum-shaped ring and the upper expanding ring to be combined with inner screw threads which are arranged on the guiding ring; the top end of the connecting rod is provided with a non-quit screw nail; an opening groove at the head end of the guiding ring extends outwards, and the outer diameter of the opening groove is greater than the still outer diameter of the upper and the lower expanding rings to be accordant with the inner diameter of the rod pipe; the upper and the lower expanding rings are provided with notches which are positioned on the tapered surfaces of the seat ring, the drum-shaped ring and the guiding ring; under the action of compacting force at both heads, the notches extend outwards. The utility model which adopts the wide-edged expanding rings has the advantages of strong locking force, stability and flexible and convenient design. The locking device for a telescopic rod pipe is suitable for being applied in telescopic rods, such as a mountaineering rod, a walking stick and a tent rod.
Description
Technical field
The utility model belongs to mechanical connecting device.Be usually used in daily living article central account bar, walking stick, mountain-climbing bar one class flexible rod.Specifically be used for connection and locking between two sections or the several sections flexible rod tubes.
Background technique
Placement between the existing flexible rod tube has many kinds, comprises tapered thread banding formula, outer expanding.A kind of single-ended outer expanding structure of splitting post piece locking of utilizing is arranged, at any position, during the phase time precession, all can realize locking, regulate simple and make things convenient for, but it is when locking, the frictional force on the surface of contact is less than normal.
Summary of the invention
The utility model is to solve the deficiency of going back locking force, can keep simple in structure, flexible characteristics again simultaneously.
Flexible rod tube of the present utility model connects uses locking device, comprise locking framework, it is characterized in that said locking framework by extension bar, collar, seat ring, down expanding ring, cydariform circle, go up expanding ring, guide collar is formed, the extension bar head end is provided with outside thread, pass seat ring, following expanding ring, cydariform circle successively, go up expanding ring, combine with internal thread set on the guide collar, its top is provided with stopping screw; The guide collar head end is opened poor outer opening, and external diameter adapts with the rod tube internal diameter greater than the static external diameter of upper and lower expanding ring; Upper and lower expanding ring is provided with notch, is positioned on the conical surface of seat ring, cydariform circle, guide collar, opens outside the notch under the effect of two impacting force.
It is protruding stupefied to be respectively equipped with guiding on described seat ring, cydariform circle, the guide collar.
Described extension bar lower end is provided with shock-proof spring.
Described collar is double-deck locate mode collar.
Good effect of the present utility model is:
1), owing to adopted the expansion loop of broadside formula, be the face contact during locking, coupling mechanism force is big, and it is little to wear and tear.
2) can connect, as required and establish two～three expansion loops, flexible design is convenient.
3), adopted shock-proof spring, feel is good, as the mountain-climbing bar the application, can bear instant impact.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the working principle schematic representation.
Among the figure: 1, extension bar; 2, seat ring; 3, following expanding ring; 4, cydariform circle; 5, go up expanding ring; 6, guide collar; 7, guiding is protruding stupefied; 8, stopping screw; 9, outside thread; 10, gap; 11, stabilizing spring; 12, connect cover; 13, collar; 14, fixed end; 15, following rod tube; 16, mouth of pipe grip; 17, go up rod tube.
Embodiment
Below the embodiment of accompanying drawing is further specified it.
Flexible rod tube connection shown in Figure 1 is used locking device embodiment, its locking framework to be installed in two sections rod tubes and is used.For telescopic rod tube is thickness pipe nested mode.Its locking framework is made up of extension bar 1, collar 13, seat ring 2, time expanding ring 3, cydariform circle 4, last expanding ring 5, guide collar 6, the extension bar head end is provided with outside thread 9, pass seat ring 2, following expanding ring 3, cydariform circle 4 successively, go up expanding ring 5, combine with internal thread set on the guide collar 6, its top is provided with stopping screw 8; The guide collar head end is opened poor outer opening, and external diameter adapts with the rod tube internal diameter greater than the static external diameter of upper and lower expanding ring; Upper and lower expanding ring is provided with notch, is serial fashion, and the broadside structure is positioned on the conical surface of seat ring 2, cydariform circle 4, guide collar 6, and outwards open in the notch footpath under the effect of two impacting force.The 12nd, spring is used connects cover.
Guide collar is provided with guiding protruding stupefied 7.It is protruding stupefied also to be provided with guiding on seat ring, the cydariform circle.
The spring 11 that the extension bar lower end is set, spring can compress when last rod tube presses down, and tangible cushioning effect is arranged.
Collar 13 is double-deck locate mode collar, plastic material.Groove fit with rod tube mouth of pipe grip 16 inboards plays the retaining effect, prevents natural slippage between bar official pipe when non-locking state.
In conjunction with Fig. 2 its working procedure is described:
The extension bar of device is installed spring earlier, is connect cover and collar, the rod tube mouth of pipe under its fixed end 14 is packed into, and mechanical fixation is integral.
In succession suit seat ring 2, down expanding ring 3, cydariform circle 4, go up expanding ring 5, make the notch of expansion loop protruding stupefied consistent with guiding, the outside thread 9 with the extension bar head end is connected with the internal thread 9 of guide collar 6 again, upward stopping screw 8 is fixed on the top.
With the poor head end guiding of opening of guide collar go up rod tube 17 running-on, with the rod tube internal diameter be flexible interference fit, upper and lower expanding ring is relaxed state, until collar 13 passes through the grip inner tank mouths.Install.
Up and down during the relative dextrorotation of rod tube 17,15, relative close between the guide collar of extension bar head end and the seat ring, the conical surface of seat ring 2, cydariform circle 4, guide collar 6 is two extruding of expanding ring up and down, and notch is opened outward when compressing, and the interior ancient piece of jade, round, flat and with a hole in its centre of outer ring surface and rod tube is adjacent to and locks.Otherwise, then can unclamp, regulate between rod tube in conjunction with extension position.
Outer Zhang Chengdu of gap 8 between seat ring 2, cydariform circle 4, the guide collar 6 and expanding ring notch and the latching force that is obtained thereof require to adapt.
