Abstract
The utility model relates to an internal locking device of a walking stick, which belongs to the field of sports goods. The internal locking device of the walking stick comprises a tube seat, and is characterized in that a screw rod is fixed on the tube seat, wherein threads are machined on the middle part of the screw rod; a conical barrel-shaped lock core is sleeved at the lower part of the screw rod; a long-strip -shaped notch is machined on the tube wall of an expansion sleeve; threads are machined on the inner cavity wall of the expansion sleeve; and the expansion sleeve is screwed on the screw rod. The internal locking device of the walking stick has athe advantages of simple structure, convenience for installation, low cost and large locking force.
Description
Technical field
The utility model relates to the sports goods field, and detailed saying is the built-in locking device of a kind of walking stick.
Background technology
Walking stick is a kind of walking aid, especially climbs the mountain, the 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 that intensity is high, easy to use, the scope of application is wide, and weak point is that single-unit formula walking stick size is long, carry inconvenience, retractable two-segment type, three-section type and four joint formulas, existing built-in retaining mechanism exists assembling complicated, and cost is high, coupling mechanism force is not enough, damages the problems such as rear maintenance difficult.
Summary of the invention
In order to overcome the technical deficiency of existing multi-section type walking stick embedded locking structure assembling complexity, maintenance difficult, coupling mechanism force, the utility model provides a kind of walking stick built-in locking device, and this retaining mechanism is simple to operate, easy for installation, cost is low, and coupling mechanism force is large, obviously improves the coupling mechanism force of multi-section type walking stick.
The utility model adopts following technical scheme: the built-in locking device of a kind of walking stick, be provided with base, it is characterized in that, be fixed with screw rod on the base, the middle part of screw rod is processed with screw thread, and the lock core of cone barrel is sleeved on the screw rod bottom, is processed with the strip breach on the tube wall of expansion sleeve, be processed with screw thread on the expansion sleeve internal chamber wall, expansion sleeve screws on screw rod.
The beneficial effects of the utility model are, simple to operate, easy for installation, cost is low, and coupling mechanism force is large.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is explosive view of the present utility model.
Fig. 2 is installation diagram of the present utility model.
1. upper baffle rings among the figure, 2. expansion sleeve, 3. lower baffle ring, 4. lock core is 5. gone up draw-in groove, 6. screw rod, 7. lower bayonet slot, 8. base.
The specific embodiment
As shown in Figure 1 and Figure 2, be provided with base 8, be fixed with screw rod 6 on the base 8, the middle part of screw rod 6 is processed with screw thread, screw rod 6 two ends circumferentially be processed with respectively draw-in groove 5 and lower bayonet slot 7, the lock core 4 of cone barrel is sleeved on screw rod 6 bottoms, lower baffle ring 3 is entrenched in the lower bayonet slot 7, lower baffle ring 3 is positioned at screw rod 6 bottoms with lock core 4, be processed with the strip breach on the tube wall of expansion sleeve 2, be processed with screw thread on expansion sleeve 2 internal chamber walls, expansion sleeve 2 screws on screw rod 6, upper baffle ring 1 is entrenched in the draw-in groove 5, and upper baffle ring 1 is positioned at expansion sleeve 2 and prevents on the screw rod 6 that expansion sleeve 2 from coming off.
When the utility model uses base 8 is bonded on the lower body of rod, the lower body of rod is sleeved in the upper body of rod, during locking, bull stick body in the dextrorotation, expansion sleeve 2 moves down, and near lock core 4, expansion sleeve 2 expands, and two pole bodies are locked.When unclamping, be rotated counterclockwise the body of rod, expansion sleeve 2 moves up, and away from lock core 4, expansion sleeve 2 shrinks, and two pole bodies are unclamped.
