Description
Technical field
The utility model relates to the sports goods field, and detailed saying is the external locking device of a kind of walking stick.
Background technology
As everyone knows: walking stick is a kind of walking aid, especially climbs the mountain, the aid of sports such as skiing and the auxiliary walking of the elderly.At present, walking stick can be divided into single-unit formula, two-segment type, three-section type and four joint formulas, uses metal or carbon fiber to make, be characterized in the intensity height, easy to use, the scope of application is wide, weak point is that single-unit formula walking stick size is long, carries inconvenience, retractable two-segment type, three-section type and four joint formulas, locking device is built-in, and assembling is complicated, the cost height, use trouble, there is the locking device obscission in effort, damages problems such as back maintenance difficult.The existing built-in locking mechanism of multi-section type walking stick, assembling is complicated, and maintenance difficult, principle all are by manually rotating back and forth the purpose that the body of rod reaches locking and separates.
Summary of the invention
The purpose of this utility model just is to overcome the deficiencies in the prior art, provides a kind of walking stick external locking device, and this locking device is simple to operate, and is easy for installation, and cost is low, obviously improves the problem that the built-in locking mechanism of multi-section type walking stick exists.Regulate the purpose that the method for spanner reaches locking by rotating external coupling mechanism force, need not to rotate back and forth the body of rod, this locking device is fixed on the body of rod outer wall, regulate the rotation of spanner by coupling mechanism force, the opening that outer tensioner is overlapped becomes big or diminishes, the change of tensioner cover opening is big or diminish in driving, thereby reaches bodies of rod locking that two thicknesses is different or the purpose of unclamping.
The utility model adopts following technical solution: the external locking device of a kind of walking stick, be provided with outer tensioner cover, outer tensioner cover gap position place is connected with the lock ear, be processed with two helicoids on the lock ear, be processed with locking hole on the lock ear, be provided with bolt block in the locking hole, the upper end of bolt block and bolt spins together, the bolt lower end is spacing on the lock ear, and bolt block is hinged through fixed pin shaft and spanner, and the bottom of spanner is processed with convex.
The utility model also can be realized by following measure: outer tensioner cover inner chamber is equipped with notched interior tensioner cover for to be made up of two cylindrical cavities that vary in size in the little cavity.
The beneficial effects of the utility model are that simple to operate, easy for installation, cost is low, locks firmly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an explosive view of the present utility model.
Fig. 2 is a cutaway view of the present utility model.
Fig. 3 is the utility model structural representation.
1. outer tensioner covers among the figure, 2. interior tensioner cover, 3. spanner, 4. bolt block, 5. bolt, 6. fixed pin shaft.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model is provided with outer tensioner cover 1, outer tensioner is overlapped 1 gap position place and is connected with the lock ear, be processed with two helicoids on the lock ear, be processed with locking hole on the lock ear, be provided with bolt block 4 in the locking hole, bolt block 4 spins together with the upper end of bolt 5, bolt 5 lower ends are spacing on the lock ear, bolt block 4 is hinged through fixed pin shaft 6 and spanner 3, the bottom of spanner 3 is processed with convex, and outer tensioner is overlapped 1 inner chamber for to be made up of two cylindrical cavities that vary in size, and notched interior tensioner cover 2 is installed in the little cavity.In the big column cavity with thick body of rod tensioner cover 1 outside insert the rear end during use, tensioner cover 2 in holding out against is fixed together the thick body of rod and outer tensioner cover 1 with jelly.
That this external retaining mechanism, interior tensioner cover 2 must be selected for use is flexible, flexible, endurance and very thin a kind of nonmetallic materials, and bolt block 4 adopts wear-resisting, fatigue proof metal material, in addition, outer tensioner cover 1 design has helicoid, spanner 3 designs have off-centre operation, and this is the key of locking.
During use, tensioner cover 2 in the thin body of rod inserts, as need locking, the spanner 3 that then turns clockwise is because outer tensioner cover 1 is provided with two helicoids, this moment is along with the rotation of spanner 3, drive bolt block 4 and rise gradually, the otch of outer tensioner cover 1 is narrowed down, at this moment along helicoid, the diameter of outer tensioner cover 1 diminishes, the openings get smaller of tensioner cover 2 produces clamping force, thereby the thin body of rod is held in driving, reach the first heavily locking, at this moment spanner 3 is closed on the outer tensioner cover 1, utilizes the cam principle, the otch of outer tensioner cover 1 further narrows down, produce clamping force once more, reach locking fully this moment.
As need separately with two pole bodies, at first open spanner 3, rotary spanner 3 counterclockwise then, this moment is along with the rotation of spanner 3, drives bolt block 4 and descends gradually along helicoid, and the opening of outer tensioner cover 1 broadens, at this moment, the diameter of outer tensioner cover 1 becomes big, and the diameter of tensioner cover 2 becomes big in driving simultaneously, thereby the thin body of rod is unclamped.
Claims (2)
1. external locking device of walking stick, be provided with outer tensioner cover, it is characterized in that: outer tensioner cover gap position place is connected with the lock ear, be processed with two helicoids on the lock ear, be processed with locking hole on the lock ear, be provided with bolt block in the locking hole, the upper end of bolt block and bolt spins together, the bolt lower end is spacing on the lock ear, and bolt block is hinged through fixed pin shaft and spanner, and the bottom of spanner is processed with convex.
2. according to the external locking device of the described walking stick of claim 1, it is characterized in that said outer tensioner cover inner chamber for to be made up of two cylindrical cavities that vary in size, is equipped with notched interior tensioner cover in the little cavity.
