Description
Technical field
The utility model relates to a kind of rope skipping card header structure, realizing the connection of rope and handle quickly and easily, and
Solve rope replacing, length adjustment inconvenience, connect illusive problem.
Background technology
Rope skipping is generally made up of handle and rope two parts, and the connection between handle and rope can be in many ways
Realize.Such as traditional monolithic construction handle, it is simply that the one end at handle is provided with the installing hole installing rope, rope very simply
Rope is fixed in installing hole.The rope skipping of this structure, during rope skipping, rope not only easily produces in the air and rocks,
And easily produce twisted phenomena at rope root, thus affect the speed of rope skipping, and when rope damages it is generally required to connect
Change in the lump with Handle of skipping rope.
In order to solve the problems referred to above, people have carried out a lot of improvement to the attachment structure between rope and handle, such as notification number
" a kind of rope skipping buckle " disclosed by CN 204485175U Y, including the buckle body of rod and the nut removably connecting, buckle
The upper end of the body of rod is provided with connection external screw thread, and the middle-end at the buckle body of rod is provided with the first ring body setting position for card, first
Being provided with the assembling through hole running through the buckle body of rod between ring body and external screw thread, the middle lower end of the buckle body of rod is provided with the second ring body, buckle
The lower end of the body of rod is provided with the 3rd ring body, forms the annular groove of indent between the second ring body and the 3rd ring body.It passes through annular groove, the second ring
The cooperation of body and the 3rd ring body can directly be connected fixing with rope skipping maintaining part, is blocked positioning by the first ring body, is led to by assembling
Rope is assembled in hole, is fixed by nut.Though the rope skipping buckle using this structure is more convenient when change rope skipping length, only need
Unload nut.But for the structure of this buckle, relative or more complicated, and cannot ensure that the connection of rope is firm.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, a kind of simple in construction of offer,
And the rope skipping card header structure that rope is convenient, fast, be securely attached on handle can be made.
The technical scheme that the above-mentioned technical problem of the utility model solution is used is: this rope skipping card header structure, including dop
Body, it is characterized in that described collet body include one its there is the sleeve pipe being available for the axially extending bore that rope passes through, outside sleeve pipe
The circumferentially shaped longitudinal opening groove having at least two to communicate with axially extending bore of wall and be positioned at groove cantilever vertically and stretch out and can
The jaw of elastic deformation；And a lock tube, can jaw on squeezing bushing and be tightly placed on sleeve pipe.
In order to there be axial limiting upwards after making lock tube load onto to it, described bushing head is also formed with a pair lock tube and rises
The circular expansion section of the radial direction of position-limiting action, its upper surface of described lock tube offsets with this circle expansion section.
Described jaw can be accomplished in several ways, and can be two or more, and circumference is arranged symmetrically with or circumference is equal
Even distribution, it is preferable that described jaw can elect two as, and circumference is arranged symmetrically with, and can be designed to expand pawl shape.
Can rotate freely on handle to make to be installed with this dop of rope, the circular expansion section on described sleeve pipe top with
The external diameter of lock tube is identical or essentially identical, from the appearance in cylinder after sleeve pipe and lock tube combination.
Compared with prior art, the utility model has the advantage of: this rope skipping dop is by the combination of sleeve pipe and lock tube, ingeniously
Utilize jaw to be securely attached on dop by rope wonderfully, not only low cost, simple in construction, rope firm grip, and
Clamp or unclamp rope, as long as activity lock tube, making the regulation of rope lengths or replacing become quite to facilitate；This card other
It is good that head rotates flexibility, can ensure that handle capable of being rotates freely during rope skipping.
Brief description
Fig. 1 is the perspective exploded view of the utility model embodiment.
Fig. 2 is the schematic perspective view after the utility model embodiment assembles.
Fig. 3 is the section of structure of the utility model embodiment.
Fig. 4 is the schematic diagram after the utility model embodiment loads onto handle.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figures 1 to 4, the rope skipping dop in the present embodiment includes sleeve 1 and a lock tube 2, sleeve pipe 1 and lock tube 2
It is moulding.Wherein
Sleeve pipe 1, with axially extending bore 11, is available for rope 3 and passes through.The head of sleeve pipe 1 has a radial direction circle expansion section 14, its
External diameter mates with the external diameter of lock tube 2, can be identical or essentially identical, and its effect axial limiting mainly to lock tube 2, to enter
One step is placed restrictions on lock tube 2 and is up moved.Outer wall below sleeve pipe 1 head is circumferentially shaped two shaft orientation opening grooves being arranged symmetrically with
13, and groove 13 communicates with axially extending bore 11, and be equipped with in groove 12 one vertically cantilever stretch out and the jaw of elastically deformable
12, jaw is outward-dipping expansion pawl shape.Using this clamping jaw structure, clamping force is big, and can utilize the outwards swollen of jaw 12
Swollen effect makes lock tube 2 tightly put on sleeve pipe 1, and slip axially or radially will not occur.And the contra bevel structure of jaw 12 can
Make lock tube 2 can move axially downwards under external force, easily lock tube 2 is unloaded or to be locked.
Lock tube 2 is a cylindrical body, can jaw 12 on squeezing bushing and be tightly placed on sleeve pipe 1, and after loading onto
Its upper surface offsets with this circle expansion section 14, from the appearance in cylinder after sleeve pipe 1 and lock tube 2 combination, to guarantee to rotate
Flexibility.
During use, as long as by one of rope 3 axially extending bore 11 passing through sleeve pipe, then put lock tube 2, upwardly lock tube
2, touch until offseting with the circular expansion section 14 of sleeve pipe, now two jaws 12 on sleeve pipe are extruded and clamp rope 3, make rope
3 are through on sleeve pipe 2 firmly, will not get loose；When wanting activity rope 3, as long as exerting a force lock tube 2 downwards, make lock tube 2 from sleeve pipe 1
On remove, after releasing extruding to jaw 12, jaw 12 elastic recovery, now rope 3 can be freely movable sleeve pipe 1 in.Cause
This use is quite convenient.
This dop also can be assembled on the handle 4 that structure therewith matches very quickly, and uses dismountable with handle 4
Structure, makes dop and handle capable of being disassembled and assembled freely, is convenient for changing rope or regulation rope lengths.
The foregoing is only preferred embodiment of the present utility model, it is noted that for those of ordinary skill in the art
For, under the premise of without departing from principle of the present utility model, multiple remodeling can be carried out to the utility model or improve, such as jaw
May be used without other patterns, quantity also can be by outer wall circumference equally distributed three or more, to lock tube spacing except
Outside circular expansion section described in the present embodiment, it is possible to using the mode of step etc., these all should be considered the utility model in a word
Protection domain within.
