Abstract
The utility model provides a ratchet -wheel type fastener, including two symmetries win, lock iron, spring pin, ratchet shaft, ratchet, torsional spring, pawl shaft, pawl in succession, be provided with the strengthening rib in winning in succession, fix with rivet is passed through to the one end of winning in succession, is flat toper, and strip shaped hole has been seted up to built -in foraminiferous lock iron on the length direction that wins in succession, the spring pin passes lock iron and strip shaped hole, but lock iron can not be for the spring pin turn right or left that slides from top to bottom, and the other end that should win in succession passes through the ratchet shaft to be connected, the ratchet shaft passes wins in succession and can rotate relatively, and the ratchet is fixed on the ratchet shaft and is located the inboard of winning in succession, is provided with pawl shaft on winning in succession, and the torsional spring twines on pawl shaft, a torsional spring end pressure is on the pawl, and even board is worn out to the other end, the pawl cooperatees with the ratchet along radially being provided with solid rope through -hole on the ratchet shaft ratchet shaft one end is provided with the pretension pinhole. The utility model discloses simple structure improves fastener intensity, convenient to use, has improved work efficiency, has reduced intensity of labour, the suitable popularization and application.
Description
Technical field
This utility model relates to a kind of for transporting binding equipment during large cargo, particularly to a kind of ratchet wheel type fastener.
Background technology
At home on Railway Transport Industry, to large cargo transport is solid binding, mostly adopts multistrand rope binding, the twisted reinforcement means tightened of lease rods. This reinforcement means sub-thread unbalance stress, complicated operation, waste are seriously, cost of transportation is higher, handling are on-the-spot disorderly and unsystematic, and goods is very easily produced in transit the situation that binding is loosening by effect of inertia, there is the hidden danger of traffic safety accident. Steel-wire fastener is a kind of loading reinforcing device being used in railway, automobile, ship cargo transport aspect, is the replacement equipment of currently used wire rod reinforcing mode. Easy to use, with low cost, time saving and energy saving, solid and reliable. But at present, due to technical perfect not, still could not replace wire rod reinforcing mode completely.
Summary of the invention
For above-mentioned weak point of the prior art, this utility model provides a kind of ratchet wheel type fastener.
To achieve these goals, this utility model provides techniques below scheme: a kind of ratchet wheel type fastener, including two pieces of symmetrical winning in succession, lock ferrum, resilient key, ratchet shaft, ratchet, torsion spring, pawl axis, ratchet, reinforcement it is provided with in winning in succession, described one end of winning in succession is fixed by rivet, in flat taper, built-in lock ferrum with holes, winning in succession, length direction offers strip hole, described resilient key is through lock ferrum and strip hole, described lock ferrum can not slide up and down relative to resilient key, can left-right rotation, this other end won in succession is connected by ratchet shaft, described ratchet shaft is through winning in succession and can relatively rotate, ratchet is fixed on ratchet shaft and is positioned at inner side of winning in succession, pawl axis it is provided with on winning in succession, torsion spring is wrapped on pawl axis, described one end is pressed on ratchet, the other end passes connecting plate, described ratchet matches with ratchet, described ratchet shaft has been disposed radially solid rope through hole, described ratchet shaft one end is provided with pretension pin-and-hole.
By above technical scheme it can be seen that this utility model simple in construction, improve fastener strength, easy to use, improve work efficiency, reduce labor intensity, suitable popularization and application.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of ratchet wheel type fastener as shown in Figure 1, symmetrical 1 is won in succession including two pieces, lock ferrum 2, resilient key 3, ratchet shaft 4, ratchet 5, torsion spring 6, pawl axis 7, ratchet 8, it is characterized in that: be provided with reinforcement 9 winning in succession in 1, described 1 one end of winning in succession is fixed by rivet 10, in flat taper, built-in lock ferrum 2 with holes, winning in succession, 1 length direction offers strip hole 11, described resilient key 3 is through lock ferrum 2 and strip hole 11, described lock ferrum 2 can not slide up and down relative to resilient key 3, can left-right rotation, this win in succession 1 the other end connected by ratchet shaft 4, described ratchet shaft 4 is through winning 1 and can relatively rotate in succession, ratchet 5 is fixed on ratchet shaft 4 and is positioned at wins in succession inside 1, it is provided with pawl axis 7 on 1 winning in succession, torsion spring 6 is wrapped on pawl axis 7, described torsion spring 6 one end is pressed on ratchet 8, the other end passes 1 connecting plate, described ratchet 8 matches with ratchet 5, described ratchet shaft 4 has been disposed radially solid rope through hole, described ratchet shaft one end is provided with pretension pin-and-hole 12, above-mentioned fastener structure is simpler, save processing cost, increase the intensity of winning in succession of stress simultaneously, meet instructions for use, suitable popularization and application.
The technical scheme above this utility model embodiment provided is described in detail, principle and the embodiment of this utility model embodiment are set forth by specific case used herein, and the explanation of above example is only applicable to the principle helping to understand this utility model embodiment; Simultaneously for one of ordinary skill in the art, according to this utility model embodiment, all will change in detailed description of the invention and range of application, in sum, this specification content should not be construed as restriction of the present utility model.
