Abstract
Telescopic traction rope major-minor drum assembling structure, belongs to telescopic traction rope technical field, including main line disk and by-pass disk, and open-topped cavity volume is provided with the middle part of main line disk, and axis hole is equipped with the main line disk and by-pass disk where the upper and lower both sides of cavity volume；Draw-in groove is evenly equipped with the madial wall of the cavity volume, the edge outwardly convex of the by-pass disk forms fastener, and the fastener is embedded in draw-in groove and locks with draw-in groove.Main line disk and by-pass disk connected mode are become buckle-type by the utility model from the fixation of original spacing preiection to be fixed, and the friction between by-pass disk and main line disk in disassembly process is greatly reduced, so as to contribute to the service life of extension telescopic traction rope.
Description
Technical field
The utility model belongs to telescopic traction rope technical field, and in particular to a kind of telescopic traction rope major-minor drum assembling knot
Structure.
Background technology
Telescopic traction rope, for the traction of pet, prevents pet from going astray from the group or losing because its operation is flexibly simple, braking is quick
Lose.Major-minor drum is made up of as the core main body of telescopic traction rope main line disk and by-pass disk.Top is provided with the middle part of main line disk
The cavity volume of portion opening, is provided with pulling plate in the cavity volume, and by-pass disk cover closes the top open part in main line disk.It is secondary in the prior art
Using spacing preiection is provided with the outer rim of main line disk cavity volume, the edge of by-pass disk directly engages for the combination of drum and main line disk
By-pass disk is fixed together with main line disk on the spacing preiection.The telescopic traction rope being made of the above method is being tieed up
By-pass disk is not easily taken out and the edge of by-pass disk can be subject to different degrees of with spacing preiection after repeatedly taking out during repairing
Abrasion, it is insecure so as to cause by-pass disk to be arranged on main line disk.
The content of the invention
For the deficiencies in the prior art, the purpose of this utility model is directed to telescopic traction rope major-minor drum dress
Distribution structure.
To achieve the above object, the utility model is using following technical scheme：
A kind of telescopic traction rope major-minor drum assembling structure, including main line disk and by-pass disk, are provided with top in the middle part of main line disk
The cavity volume of portion opening, axis hole is equipped with the main line disk and by-pass disk where the upper and lower both sides of cavity volume；The inner side of the cavity volume
Be evenly equipped with draw-in groove on wall, the edge outwardly convex of the by-pass disk forms fastener, the fastener be embedded in draw-in groove and with card
Slot lock is consolidated.
Further, the upper end of the draw-in groove is provided with inwardly projecting fixture block, and the lateral surface of the fastener is provided with and fixture block
The snap fit for matching.
Further, it is equipped with the reinforcement being interspersed on the main line disk and by-pass disk.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
The telescopic traction rope major-minor drum assembling structure that the utility model is provided, by main line disk and by-pass disk connected mode from
Originally spacing preiection is fixed and becomes buckle-type and fix, and greatly reduces in disassembly process between by-pass disk and main line disk
Friction, so as to contribute to the service life of extension telescopic traction rope.
Brief description of the drawings
Fig. 1 is overlooking the structure diagram of the present utility model.
Fig. 2 is the schematic cross-sectional view in Fig. 1 along D-D directions.
Fig. 3 is the schematic cross-sectional view in Fig. 1 along C-C directions.
In figure：1. main line disk；2. by-pass disk；3. fastener；4. draw-in groove；5. cavity volume；6. axis hole.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment：
With reference to shown in Fig. 1, Fig. 2 and Fig. 3：A kind of telescopic traction rope major-minor drum assembling structure, including main line disk 1 and by-pass
Disk 2, the middle part of main line disk 1 is provided with open-topped cavity volume 5, main line disk 1 and by-pass disk 2 of the cavity volume about 5 where both sides
On be equipped with axis hole 6, is placed with pulling plate in cavity volume 5, pulling plate middle part is again provided with axis hole.On the madial wall of the cavity volume 5
Draw-in groove 4 is furnished with, the edge outwardly convex of the by-pass disk 2 forms fastener 3, and the fastener 3 is embedded in draw-in groove 4 and and draw-in groove
Locking.The reinforcement being interspersed is equipped with the main line disk 1 and by-pass disk 2, strengthens overall intensity.
With reference to shown in Fig. 2 and Fig. 3, the upper end of the draw-in groove 4 is provided with inwardly projecting fixture block, the lateral surface of the fastener 3
It is provided with the snap fit matched with fixture block.When by-pass disk 2 is arranged on main line disk 1, snap fit can block fixture block, so that secondary
Drum 2 is fixed on main line disk 1.
By original using spacing preiection is provided with cavity volume outer rim, by-pass disk is directly fastened on the limit convex to the utility model
The assembling mode for rising becomes by-pass disk buckle-type and is connected on main line disk.Compared to the past, buckle-type connect cause by-pass disk with
Friction between main line disk is reduced, and the fastener effectively extended in the service life of by-pass disk and main line disk, and by-pass disk is stretched
Enter to main line disk so that fastening effect between the two is more preferably.
Below only most preferred embodiment of the present utility model is described, but is not to be construed as the limit to claim
System.The utility model is not limited only to above example, all to be made in the protection domain of the utility model independent claims
Various change is in protection domain of the present utility model.
