The locking device comprises a column-shaped tube base and is characterized in that a conical platform-shaped lower lock core is sleeved on the column-shaped tube base, and two outer side walls of the lower lock core are provided with a side ear respectively; the front part of the column-shaped tube base is provided with threads; an upper lock core which is in a shape of inverted frustum is screwed on the threads, and two outer side walls of the upper lock core are provided with a side ear respectively; one side wall of a tightening sleeve is provided with a tightening groove, and the other side wall of the tightening sleeve is provided with a groove; the tightening sleeve is sleeved on the upper lock core and the lower lock core, and the two side ears of the upper lock core and the two side ears of the lower lock core are positioned in the groove as well as the tightening groove of the tightening sleeve.

Description

The built-in bidirectional locking device of walking stick

Technical field

The utility model relates to the sports goods field, and detailed saying is the built-in bidirectional 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, and is 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, carries inconvenience; Retractable two-segment type, three-section type and four joint formulas, locking device is built-in, and assembling is complicated, and cost is high; Use trouble, there is the locking device obscission in effort, damages problems such as back maintenance difficult.Existing built-in one-way locking mechanism exists assembling complicated, and cost is high, and coupling mechanism force is not enough, damages problems such as back maintenance difficult.

Summary of the invention

The purpose of the utility model just is to overcome the deficiency of prior art, provides a kind of walking stick built-in bidirectional locking device, and this retaining mechanism is simple to operate, and is easy for installation, and cost is low, and coupling mechanism force is big, obviously improves the coupling mechanism force of multi-section type walking stick.

The utility model adopts following technical solution: the built-in bidirectional locking device of a kind of walking stick, be provided with the base of cylindricality, and it is characterized in that: the following lock core that is set with a taper type on the base of cylindricality; Being processed with one respectively on two lateral walls of following lock core picks up the ears; The front portion of cylindricality base is processed with screw thread, and the upper lock core of inversed taper platform shape screws on screw thread, is processed with one respectively on two lateral walls of upper lock core and picks up the ears; Swelling is overlapped a sidewall and is processed with expanding trough; Be processed with groove on another sidewall of swelling cover, the swelling cover is sleeved on upper lock core and down on the lock core, and on the upper lock core two two pick up the ears and two groove and expanding troughs of picking up the ears to be positioned at the swelling cover on the lock core down.

The utility model also can be realized through following measure: the end of base is processed with screw rod, is combined with nut on the screw rod.

The beneficial effect of the utility model is, this retaining mechanism is simple to operate, and is easy for installation, and cost is low, and coupling mechanism force is big, obviously improves the coupling mechanism force of multi-section type walking stick.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the explosive view of the utility model.

1. nuts among the figure, 2. upper lock core, 3. the swelling cover 4. descends lock core, 5. base, 6. screw rod.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, to help the content of understanding the utility model.

As shown in Figure 1, the utility model is provided with the base 5 of cylindricality, is set with the following lock core 4 of a taper type on the base 5 of cylindricality; Be processed with one respectively on two lateral walls of following lock core 4 and pick up the ears, the front portion of cylindricality base 5 is processed with screw thread, and the upper lock core 2 of inversed taper platform shape screws on screw thread; Being processed with one respectively on two lateral walls of upper lock core 2 picks up the ears; Swelling is overlapped 3 one sidewalls and is processed with expanding trough, is processed with groove on swelling cover 3 another sidewalls, and swelling cover 3 is sleeved on upper lock core 2 and the following lock core 4; On 2 liang of the upper lock cores two pick up the ears and two groove and expanding troughs of picking up the ears to be positioned at swelling cover 3 on the lock core 4 down; The end of base 5 is processed with screw rod 6, is combined with nut 1 on the screw rod 6, prevents that upper lock core 2 from screwing out.

The utility model base 5 lower ends and the body of rod are adhesively fixed, during locking, and the body of rod that turns clockwise, upper lock core 2 moves down, and near following lock core 4, swelling cover 3 expands, and two pole bodies are locked.

When unclamping, be rotated counterclockwise the body of rod, upper lock core 2 moves up, and away from following lock core 4, swelling cover 3 shrinks bloated, and two pole bodies are unclamped.

Claims

1. built-in bidirectional locking device of walking stick is provided with the base of cylindricality, it is characterized in that: the following lock core that is set with a taper type on the base of cylindricality; Being processed with one respectively on two lateral walls of following lock core picks up the ears; The front portion of cylindricality base is processed with screw thread, and the upper lock core of inversed taper platform shape screws on screw thread, is processed with one respectively on two lateral walls of upper lock core and picks up the ears; Swelling is overlapped a sidewall and is processed with expanding trough; Be processed with groove on another sidewall of swelling cover, the swelling cover is sleeved on upper lock core and down on the lock core, and on the upper lock core two two pick up the ears and two groove and expanding troughs of picking up the ears to be positioned at the swelling cover on the lock core down.

2. according to the built-in bidirectional locking device of the said walking stick of claim 1, it is characterized in that the end of said base is processed with screw rod, be combined with nut on the screw rod.
