Description

A kind of traction rope buckle

Technical field

The utility model belongs to the technical field of traction rope, is related to a kind of traction rope buckle.

Background technique

The place that the stream of people as market, recreation ground concentrates, the area that often adult also usually enters and leaves with children Domain, due to the gap of adult and child height, in addition often height is inadequate by children, once be blocked or the stream of people extruding The case where just will appear the case where wandering away without being discovered by adult down, thus children being easily caused to lose.Children loss Have become the social concern of whole world concern, annual China just there are a large amount of children loss, there are some youngsters on the market at present Anti-lost wrist-watch product used in child, most preventing child ring of giving up are mainly based upon GSM mobile handset technology to develop.By Ring group is given up in GSM mobile handset technological development in the preventing child, is easy so that cost is very high, and often to charge, very It is severely exceeded to the radiofrequency signal having, is unable to satisfy the demand of broad masses of the people.

Chinese utility model patent CN206434101U discloses a kind of preventing child and goes astray from the group traction rope, including wrist strap one, wrist Band two, telescopic traction rope, connector, fixed ring and intermediate junction device, the wrist strap one include ring set, velcro, adhesive tape one, Adhesive tape two and retaining ring, the both ends of telescopic traction rope are separately connected wrist strap one, wrist strap two, and connector includes the body of rod, connecting column and company Connector, the body of rod pass through connecting column fixed connector, connection in the cylindrical shape that radius successively reduces from top to bottom, the top of the body of rod Column is in cylindrical body, and connector is in the cylindrical shape that radius is sequentially increased from top to bottom, opens up cross recess on connector, centre connects Connection device is equipped with annulus, and the internal diameter of annulus is greater than the diameter of connecting column, and is less than the diameter of connector lower surface, and connector is logical Connector is crossed to be fixed on intermediate junction device across annulus rotation.

Disadvantage is that wrist strap is fixed by velcro, can pull open easily, even if children due to strength problem without Method is pulled open, also can be to criminal with opportunity.

Utility model content

In view of the shortcomings of the prior art, the utility model provides a kind of traction rope buckles, and lock core is increased in buckle, So that buckle can only use specific keys that could open, safety is greatly strengthened.

In order to solve the above technical problems, the purpose of this utility model is achieved by following technical proposals:

A kind of traction rope buckle, including the pin thread and female thread for wearing fixed tractive both ends, the front end of the pin thread It is relatively set with the clamp for being inserted into female thread cavity and being mutually clamped with two side bayonet slot of female thread, has been centrally located in the female thread pluggable The lock core of valid key rotation, the locating part rotated with lock core is provided on the outer wall of the lock core, and locating part hangs down positioned at clamp Snap-lock when straight position.

The structure of above-mentioned lock core is lock core structure well known to this technical field of lockset, such as lock cylinder.

Above-mentioned locating part includes pedestal and two limited blocks vertical with pedestal, and the bottom of the limited block is integrally formed Pedestal two sides are provided with through-hole on the pedestal, are set in lock core bottom.

Above-mentioned card slot be indent arc, the inside and outside wall of clamp is the arc of evagination, be provided on the inner wall of clamp and The opposite auxiliary stopper block of locating part, the outer end face of auxiliary stopper block is parallel with limited block when snap-lock.

The outer end face of above-mentioned lock core is provided with end cap, and the end cap is mounted on the seam allowance on female thread surface, below end cap Fixed block is provided on outer wall of lock core, end cap is fixed on female thread by fixed block, and then lock core is fixed on female thread.

Cavity open at one end is provided in above-mentioned clamp.

Compared to the prior art the utility model, has the following beneficial effects:

The buckle of the utility model can only could be opened by specific key, and key is worn in parent's hand, both may be used To prevent children from voluntarily unlocking, criminal is also possible to prevent by common key or simple unlocking tool and opens buckle, greatly The safety of traction rope is improved greatly.

Specific embodiment

The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-5:

A kind of traction rope buckle, including the pin thread 1 and female thread 2 for wearing fixed tractive both ends, before the pin thread 1 End is relatively set with the clamp 3 for being inserted into 2 cavity of female thread and being mutually clamped with 2 liang of side bayonet slots of female thread, has been centrally located in the female thread 2 It can be inserted into the lock core 5 that valid key 4 rotates, the locating part 6 rotated with lock core 5, locating part be provided on the outer wall of the lock core 5 6 be located at 3 upright position of clamp when snap-lock.

The lock mode of the utility model is: when locating part 6 is located at 3 upright position of clamp, locating part 6 is interior with clamp 3 Wall is opposite, and locating part 6 limits clamp 3 and inside deformation occurs, and clamp 3 can not inwardly also can not be just detached from female thread 2 in deformation Card slot, can also there are a little at this point, locating part 6 can be set to connect with 3 inner wall of clamp and then by snap-lock Perhaps gap.When unlock, rotate key 4, locating part 6 made to reach the position parallel with clamp 3, can not again the deformation to clamp 3 into Row limitation, pressing clamp 3 make clamp 3 be detached from the card slot of female thread 2, extract pin thread 1, complete unlock.

The structure of above-mentioned lock core 5 is lock core structure well known to this technical field of lockset, such as lock cylinder.

Compare attached drawing 3, the specific structure of above-mentioned locating part 6 is: locating part 6 includes that pedestal 6a and two are vertical with pedestal 6a Limited block 6b, the limited block 6b bottom be integrally formed be provided with through-hole on the two sides pedestal 6a, the pedestal 6a, be arranged In 5 bottom of lock core.

Compare attached drawing 5, above-mentioned card slot is the arc of indent, and the inside and outside wall of clamp 3 is the arc of evagination, clamp 3 it is interior It is provided with the auxiliary stopper block 7 opposite with locating part 6 on wall, the outer end face and limited block 6b of auxiliary stopper block 7 when snap-lock In parallel.Since the inner wall of clamp 3 is arc, in order to preferably cooperate with limited block 6b, it is provided with auxiliary stopper block 7.

Compare attached drawing 3, the mounting structure of lock core 5 is: the outer end face of above-mentioned lock core 5 is provided with end cap 8, and the end cap 8 is pacified On the seam allowance on 2 surface of female thread, it is provided with fixed block 9 on 5 outer wall of lock core of 8 lower section of end cap, fixed block 9 is fixed by end cap 8 It is fixed on female thread 2 on female thread 2, and then by lock core 5.

It is provided with cavity open at one end in above-mentioned clamp 3, to save material.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
