The most described lock shaft two ends are provided with retaining rib；Described trepanning internal side wall is provided with the back stop slot of corresponding retaining rib.
The most described trepanning internal side wall is additionally provided with buckle；Trepanning sidewall is fixed in described buckle lower end, and buckle upper end extends to trepanning center and forms the inclined-plane of inclination；Described trepanning sidewall and buckle upper side are around forming back stop slot.
The most described lock shaft end is provided with anti-rotation rib；Described trepanning internal side wall is provided with the anti-rotation groove of corresponding anti-rotation rib；When described lock shaft enters trepanning, the upset of anti-rotation rib enters in anti-rotation groove.
The most described lock sleeve is provided with the counterweight hole that at least two is parallel with trepanning.
The most described lock sleeve lower surface is provided with and limits the restriction rib that frenulum moves left and right；Described restriction rib is parallel with the winding direction of frenulum.
The present invention have tying firm and solid reliable, intensity is good, lightweight, technological operation is easy, tying efficiency advantages of higher, additionally this fastener is also equipped with auto-lock function, it is possible to well by frenulum locking and be difficult to not get loose.

Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.This fastener is primarily adapted for use in the frenulum of concrete block and ties up, including lock sleeve 1, lock shaft 2, flexible link belt 3, lock sleeve 1 and lock shaft 2 are linked together by flexible link belt 3, as shown in Fig. 1～7, lock sleeve 1 is provided with the trepanning 4 accommodating lock shaft 2, lock shaft 2 is turning to be entered in trepanning 4, lock sleeve 1, lock shaft 2 and flexible link belt 3 all use PA66 nylon material to be made, this material has the highest intensity, the strength after the arrangement of concrete block can be suitable for pull, and this material is prone to molding, easy to process.
The two ends of lock shaft 2 are provided with retaining rib 5, and retaining rib 5 is the projection of triangle for cross section, with lock shaft 2 integrated injection molding.Corresponding trepanning 4 is provided with the buckle 6 coordinated with retaining rib 5, when described lock shaft 2 enters in trepanning 4, effect is pullled by the extruding of frenulum 11, lock shaft 2 moves down, retaining rib 5 extrudes buckle 6 makes buckle 6 shrink, when the lower end in contact of upper end and the buckle 6 of retaining rib 5, buckle 6 is fastened togather with retaining rib 5, and lock shaft 2 now is the most rotatable with lock sleeve 1.Such be provided in frenulum 11 snap close well after, auto lock, and this locking mechanism must not turn round, and locks tighter and tighter, convenient operation, is conducive to accelerating job schedule.
In order to further facilitate installation, the also end at lock shaft 2 is provided with anti-rotation rib 9, and the inside of trepanning 4 is additionally provided with the anti-rotation groove 10 of corresponding anti-rotation rib 9, and when lock shaft 2 enters in trepanning 4, anti-rotation rib 9 is also in anti-rotation groove 10.It is to prevent from lock shaft 2 from rotating in trepanning 4 to cause frenulum 11 to get loose that anti-rotation rib 9 acts on one, and two installations being advantageous for lock shaft 2 do not have error.
Lock sleeve 1 arranges 6 counterweight holes 8 parallel with trepanning 4, primarily to increase the intensity of this fastener.
The back side of lock sleeve 1 is additionally provided with restriction rib 7, and after frenulum 11 passes from the space of lock shaft 2 and trepanning 4, frenulum 11 is adjacent to the lower surface of lock sleeve 1, limits rib 7 and is possible to prevent swinging of frenulum 11 to prevent getting loose of frenulum 11.
During assembling, such as Fig. 8～10, first frenulum 11 is tied up around concrete block, A by frenulum 11, B two ends are coiled into a ringlet according to the specification of trepanning 4 side by side, lock sleeve 1 is enclosed within ringlet and will pass from trepanning 4 by ringlet, being filled in by lock shaft 2 in ringlet again and overturning enters in trepanning 4, pull the two ends that frenulum 11 is arranged side by side simultaneously, applying downward pressure to lock shaft 2 forces the retaining rib 5 on lock shaft 2 to be fastened togather with the buckle 6 in trepanning 4, anti-rotation rib 9 on lock shaft 2 is also in the anti-rotation groove 10 in trepanning 4 simultaneously, i.e. complete the installation of frenulum and fastener, as long as applying this fastener of pulling force to frenulum 11 and will locking tighter and tighter.
Using PA66 macromolecule new material to make lock sleeve 1 and lock shaft 2, material flexibility is good, and intensity is high, stretch-proof function admirable.In-25 DEG C of+85 DEG C of temperature ranges, stable mechanical performance, the most long-time use is without deformation.Stable chemical performance in water, does not ruptures without hydrolysis and long-time illumination, and service life was more than 20 years.The main performance index of described PA66 macromolecule new material is shown in Table 1:
The main performance index of table 1:PA66 macromolecule new material
The present invention have tying firm and solid reliable, intensity is good, lightweight, technological operation is easy, tying efficiency advantages of higher, additionally this fastener is also equipped with auto-lock function, it is possible to well by frenulum locking and be difficult to not get loose.
