Description
Technical field
The utility model belongs to sports goods field, one-way locking mechanism built in specifically a kind of walking stick.
Background technology
Walking stick is a kind of walking Auxiliary support tool, be mainly used for outdoor sports mountain-climbing, skiing and on foot, simultaneously
Be also the elderly and leg disabled person walking Auxiliary support tool, existing walking stick be divided into single-unit formula, two-segment type, three-section type and
Four section formulas, the body of rod is made using metal or carbon fiber, its advantage is that intensity is high, light-weight, easy to use, the disadvantage is that：Single-unit formula
Walking stick size is long, inconvenient to carry, and the built-in retaining mechanism assembly of multi-section type walking stick is complicated, of high cost, coupling mechanism force is insufficient, repair is tired
It is difficult.
Invention content
For overcome the deficiencies in the prior art, one-way locking mechanism built in a kind of walking stick of the utility model offer,
It is changed into the rotary motion of tube socket with worm drive principle the linear motion of axis pin, passes through expansion sleeve circular cone
The variation of hole size is realized the expansion of expansion sleeve and is loosened, and completes axis pin using power transmission spiral self-locking principle and tube socket screw thread revolves
Next self-locking completes the one-way locking of more piece walking stick using the reversed stress locking technology of expansion sleeve, makes single built in the walking stick
Have to retaining mechanism：It is simple in structure, easy for installation, work safety, advantage of low cost, easy to maintenance.
Technical solution adopted by the utility model to solve its technical problems is：One-way locking mechanism built in a kind of walking stick,
Including axis pin, expansion sleeve and tube socket, which is characterized in that there is circular ring shape protrusion and circular ring shape to stop on the cylinder of cylindrical tube socket one end
Mouthful, the outer round surface of circular ring shape seam allowance to the other end has triangular groove, and tube socket endoporus is threaded, and swelling set upper side is circular cone
Hole is evenly equipped with positioning expansion slot, and expansion sleeve lower end endoporus has toroidal cavity to be engaged with the circular ring shape protrusion of tube socket periphery,
Axis pin top is that cone is evenly equipped with locating piece, and be screw shaft lower part in the middle part of axis pin has circular hole, axis pin to be packed into swelling for optical axis
After the meshing-body of set and tube socket, rotation tube socket will screw out optical axis circular hole in the nut of axis pin screw rod screw-in tube socket and be inserted into shop bolt
And it is fixed.
The utility model can be also achieved by the following measures：The positioning expansion slot of swelling set upper side and determining for axis pin top
Position block, which corresponds, is both configured to three.The thickness of locating piece is less than the width of expansion sleeve positioning expansion slot, the length of locating piece
Less than the depth that expansion sleeve positions expansion slot, the top outside diameter of locating piece is less than expansion sleeve outer diameter.
The utility model has the beneficial effects that the rotary motion of tube socket is changed into the straight of axis pin with worm drive principle
Line moves, and the variation after being moved by axis pin cone after expansion sleeve conical bore stress is realized the expansion of expansion sleeve and loosened, profit
With the self-locking after power transmission spiral self-locking principle completes axis pin and tube socket screw thread screws, the reversed stress of expansion sleeve is utilized to lock technology
The one-way locking for realizing more piece walking stick makes one-way locking mechanism built in the walking stick have：Simple in structure, easy for installation, work
Advantage safe, of low cost, easy to maintenance.
Description of the drawings
Fig. 1 is the utility model explosive view.
Fig. 2 is the utility model section view.
1. axis pin in figure, 2. expansion sleeves, 3. tube sockets, 4. shop bolts, 5. positioning expansion slots, 6. locating pieces, 7. annulus
Shape seam allowance, 8. triangular grooves, 9. circular ring shapes protrusion, 10. toroidal cavities.
Specific implementation mode
The utility model includes axis pin 1, expansion sleeve 2 and tube socket 3, has circular ring shape convex on the cylinder of 3 one end of cylindrical tube socket
Rise 9 and circular ring shape seam allowance 7, the outer round surface of circular ring shape seam allowance 7 to the other end have triangular groove 8, the interior pore area spiral shell of tube socket 3
Line, 2 upper end of expansion sleeve are that conical bore is evenly equipped with positioning expansion slot 5, toroidal cavity 10 and the tube socket 3 of 2 lower end endoporus of expansion sleeve
Circular ring shape protrusion 9 on cylinder engages, and the top of axis pin 1 is that cone is evenly equipped with locating piece 6, and the middle part of axis pin 1 is screw shaft
Lower part is optical axis band circular hole, and the positioning expansion slot 5 that the locating piece 6 of axis pin 1 is aligned to expansion sleeve 2 is packed into expansion sleeve 2 and tube socket 3
The screw rod of axis pin 1 is screwed in the nut of tube socket 3 and screws out optical axis circular hole and be inserted into shop bolt 4 and solid by meshing-body, rotation tube socket 3
Fixed, the positioning expansion slot 5 of 2 upper end of expansion sleeve is corresponded with the locating piece 6 on 1 top of axis pin is both configured to three.Locating piece 6
Thickness is less than the width of expansion sleeve positioning expansion slot 5, and the length of locating piece 6 is less than the depth that expansion sleeve 2 positions expansion slot 5, fixed
The top outside diameter of position block 6 is less than 2 outer diameter of expansion sleeve.In the connection that more piece walking stick is stretched, by a whole set of built-in list adjusted
It is cemented with subordinate telescopic rod after filling viscose glue to the triangular groove 8 of retaining mechanism tube socket 3, built-in one-way locking mechanism is packed into
Higher level's telescopic rod, built-in one-way locking mechanism and subordinate's telescopic rod can move back and forth reality in the circular hole of higher level's telescopic rod at this time
Now stretch, can be according to the rotation direction of axis pin 1 and 3 thread connection of tube socket, the rotation side of subordinate's telescopic rod when determining locking or disengaging
Axis pin 1 is rotated therewith to 3 nut of rotation subordinate telescopic rod tube socket when, locking to move in a straight line, the cone gradually pressing of axis pin 1
On the conical bore of expansion sleeve 2, it is pressed on the inner wall of higher level's telescopic rod as the increase conical bore of pressure gradually opens expansion
Two-stage is stretched rod locking, because 1 screw rod of axis pin and 2 nut of tube socket are that power transmission spiral expanding bar tightens rear self-locking, in addition, according to more
It saves after walking stick loading characteristic expansion sleeve 2 uses reversed stress locking technology expansion sleeve conical bore to open expansion and is bearing axially instead
It is expanded outwardly and inner wall one-way locking, when needing to put away sports equipment, opposite direction rotation when according to locking to expansion sleeve conical bore when power
Subordinate's telescopic rod, the cone on axis pin 1 are unclamped from the conical bore of expansion sleeve 2, and expansion sleeve Stepwize Shrink restores flexible with higher level
The inner wall of bar is detached from.
