Abstract
The utility model discloses a high-strength taper pin connecting device, which includes a ratchet rod, a ratchet wheel and a spring taper pin. The high-strength taper pin connecting device is characterized in that a reinforcing device is arranged on the inside of the spring taper pin, and the reinforcing device is an enhanced spring taper pin matched with the spring taper pin. The high-strength taper pin connecting device utilizes the mutual action of the two spring taper pins to generate the expansion and each taper pin adopt 65mm carbon constructional quality steel, so that the utility model achieves fastening and connecting functions, avoids accident occurrence when a customer uses the device without caring the safety-pulling caution, greatly improves the safety performance of the product, and improves the safety coefficient by 6 to 8 times.
Description
Technical field
The utility model relates to a kind of rigging ratchet-type strainer, relates in particular to a kind of high strength taper pin connecting device of ratchet-type strainer.
Background technology
Binding process in the transportation of automobile goods and materials, particularly full-sized car transports in the binding such as " bulldozer, excavating machine " safety, need use the ratchet-type strainer, the ratchet-type strainer is the ratchet drive ratchet rotating cylinder rotation by self, causes the two ends object to be tension.Be not subjected to the influence of external force under the quiescent conditions, the variation of matter can not take place in self; Be subjected to the influence of external force under the current intelligence, because improper use or clashed by external force is subjected to the influence of several application forces and shearing force simultaneously, the as easy as rolling off a log safety factor that causes reduces.And sell ratchet-type strainer use A3 the taper pin of common straightcarbon steel on the market, in the use, the client is under the situation of ignoring security warning, steel pipe in addition on the handle body of straining ratchet very likely, realize that leverage, application force at this moment all concentrate on the taper pin that " ratchet tube and ratchet " be connected, and form shearing force, safety misadventure takes place in instantaneous can the cut-out.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of high strength taper pin connecting device, raising product safety performance, increase safety factor.
For solveing the technical problem, technical solution adopted in the utility model is: a kind of high strength taper pin connecting device, comprise sour jujube bar, ratchet rotating cylinder, ratchet, spring taper pin, and it is characterized in that: on the described spring taper pin stiffening device is set.
Above-mentioned high strength taper pin connecting device, described stiffening device is arranged on spring taper pin inside; The reinforcement spring taper pin of described stiffening device for matching with the spring taper pin.
Above-mentioned high strength taper pin connecting device, its spring taper pin and reinforcement spring taper pin all adopt the 65mm carbon constructional quality steel.
The utility model adopts 2 taper pin mutual actions and produces and expands, and taper pin all adopts the 65mm carbon constructional quality steel, play and strengthen fastening and interconnect function, when having avoided the client to use exceeding safe pulling force caution, accident meets accident, increased substantially the security of products energy, safety factor has improved 6-8 doubly.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As Fig. 1 Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, straining ratchet is by rotary handle body 1, driving ratchet 4 rotates, ratchet 4 drives 2 rotations of ratchet rotating cylinder by the taper pin that is connected on ratchet 4 and the ratchet rotating cylinder 2, ratchet rotating cylinder 2 inwardly moves simultaneously by the sour jujube bar 3 that the internal whorl device drives two ends, reaches the purpose at tension two ends.
The utility model is a kind of high strength taper pin connecting device, comprises sour jujube bar 3, ratchet rotating cylinder 2, ratchet 4, spring taper pin 5, and a stiffening device is set on the spring taper pin 5, and its stiffening device is arranged on spring taper pin inside; The reinforcement spring taper pin 6 of its stiffening device for matching with the spring taper pin.Spring taper pin 5 and reinforcement spring taper pin 6 all adopt the 65mm carbon constructional quality steel.
