The utility model relates to a tightener which comprises connecting rods (1), a multiple-tooth strength detent (2), a ratchet wheel (3), a connecting shaft (4), etc. Two ends of the two connecting rods (2) are respectively connected together by utilizing the connecting shaft (4) and a ratchet wheel shaft (6); the ratchet wheel (3) is fixed outside of one of the connecting rods (1) by the ratchet wheel shaft (6); the multiple-tooth strength detent (2) is fixed outside of the connecting rods (1) by a detent shaft (9) passing through the connecting rods (1); a tooth part on the multiple-tooth strength detent (2) is meshed with the ratchet wheel (3) with multiple teeth; a strength rubber molding gasket (5) is sleeved outside of the connecting shaft (4); the ratchet wheel shaft (6) connected between the two connecting rods (1) is hollow and is provided with a steel wire inlet inclined hole (11), and a steel wire outlet hole (14) communicated with the steel wire inlet inclined hole (11) is arranged at one end of the ratchet wheel shaft (6) near the ratchet wheel (3), and a solid hole is arranged at the other end of the ratchet wheel shaft (6). The ratchet wheel shaft can be rotated for bundling the goods in the middle by tools such as a cephalic plate, and the like, thereby greatly improving the working efficiency for bundling.
Description
Technical field
The utility model relates to the ratchet-type fastener, belongs to field of transport machinery.
Background technology
Be applied in the common ratchet-type fastener product of the fastening timber of binding, coil of strip sheet material and other items in the railway transportation at present, mainly combine by connecting rod, lock iron, retaining divider, duplex ratchet device and steel rope.This kind fastener uses feedback through for many years, because the complex structure cost is higher, there are two because of before and after the steel rope in addition, promptly fixing one is to be fixed on the ratchet shaft and to adopt the pretension pin to connect to cooperate, because of the degree of tightness that occurs now and then on the cooperating problem that differs the phenomenon that steel rope is drawn out often takes place has produced potential safety hazard; And needs of another activity lock iron from fastener and partly pass, and are very inconvenient again in the operation, cause to take a lot of work and time-consuming.
Summary of the invention
Technical problem to be solved in the utility model is: design a kind of simple in structure, cost is low, swift and convenient to operate, steel rope is difficult for the ratchet-type fastener that is drawn out, can eliminates safe hidden trouble.
Technical solution of the present utility model: a kind of ratchet-type fastener, form by connecting rod, multiple tooth powerful ratchet, ratchet, adapter shaft, powerful rubber and plastic packing ring, ratchet shaft, circlip for shaft, torsion spring, pawl axis and packing ring; Two ends of two connecting rods connect together with adapter shaft and ratchet shaft respectively, ratchet is fixed therein the outside of a connecting rod by ratchet shaft, the pawl axis that multiple tooth powerful ratchet is passed above-mentioned connecting rod is fixed on the outside of above-mentioned connecting rod, tooth portion on the multiple tooth powerful ratchet and the multiple tooth engagement of ratchet reach the multiple tooth stressed respectively purpose that improves supporting power (intensity); Torsion spring and packing ring are contained on the pawl axis, and in order to further fixing multiple tooth powerful ratchet, the circlip for shaft pad is on ratchet shaft, and in order to further fixed ratchet wheel axle, powerful rubber plastic pad snare is used for preventing steel rope to skid in the adapter shaft outside; Be connected the ratchet shaft hollow between two connecting rods and steel rope inlet inclined hole is arranged, at ratchet shaft one end the one steel rope egress hole that communicates with steel rope inlet inclined hole is arranged near ratchet, the other end of ratchet shaft is square solid hole, with instruments such as wrench be rotatable ratchet shaft with tense wire rope, bind intermediate goods.
The utility model has been eliminated the weak link of common ratchet-type fastener, has optimized product structure, makes it dimension reduction, and cost of product reduces.
The utility model has been done change with the placement of former steel rope two heads, being about to the former steel rope head that is fixed on the ratchet shaft changes into and is fixed on adapter shaft, and adopt aluminum alloy gland mode to connect fastening, in addition need now change the mode that penetrates in the ratchet shaft inclined hole into by lock iron with one of the steel rope of activity is former, operate very convenient.
The utility model improves the position of two placements of steel rope, and movable one steel rope head is after ratchet shaft steel rope inlet inclined hole penetrates, and the rotation steel rope by ratchet shaft is difficult for being drawn out, and has eliminated potential safety hazard, thereby has guaranteed safety.
The utility model after improving all can reach requirement by the ultimate tension test, and though than original product on the cost, in the operation and in the safety all tool improve a lot and other field of adaptation same use.
The utility model can omit the steel rope welding and by operations such as bundle part pretensions, improve the work efficiency of tying up greatly, has reduced product and use cost thereof, has improved value-added content of product.
