The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Embodiment one
This chain-type strainer is used to bundle the goods on the transporting equipments such as automobile, train, boats and ships, prevent goods cause because of jolting, rocking the displacement or be scattered.
As depicted in figs. 1 and 2, this chain-type strainer comprises body 1, handle 2, retaining tooth plate 3, handle 4, chain 5 and rotating shaft 6, be connected with hook 1 by chain 5 on the body 1, handle 2 is hinged on the body 1 by rotating shaft 6, be fixed with ratchet 8 in the rotating shaft 6, retaining tooth plate 3 elasticity are connected on the body 1 and owing to the elastic force effect keeps off tooth plate 3 and are embedded on the ratchet 8,4 elasticity of shaking hands be connected on the handle 2 and since elastic force effect handle 4 be embedded on the ratchet 8, one end of chain 5 is fixed with hook 29, the other end is a free end, rotating shaft 6 is provided with by the rotation of rotating shaft 6 can stir the shifting part 10 that chain 5 moves, chain 5 be around on the shifting part 10 and link up with 29 and free end all stretch out body 1.When needing restraint of loads, hook 1 and hook 29 are hung in the both sides of goods, turning handle 2 then, rotating shaft 6 is rotated, thereby tighten up chain 5, owing to be fixed with ratchet 8 in the rotating shaft 6, retaining tooth plate 3 on the body 1 and the handle 4 on the handle 2 are flexible connection, can be embedded in all the time between the ratchet 8b of ratchet 8, make the rotating shaft 6 can only one-directional rotation.
As shown in Figure 3 and Figure 4, above-mentioned shifting part 10 is connected between the ratchet 8 and is concentric with ratchet 8, all offers the axis hole 8a that communicates on shifting part and the ratchet 8.Shifting part 10 is made up of the shifting block 10b of the some protrusions of the tubular cylindrical shell 10a and the cylindrical shell 10a outside, the plectrum 10c that this shifting block 10b is the L shape by two and is symmetricly set in cylindrical shell 10a sidepiece constitutes, and the distance of the outer end of plectrum 10c between the bending of cylindrical shell 10a middle part and its two plectrum 10c outer end is slightly larger than the thickness of chain link in the chain 5.Chain 5 is on shifting part 10 time, and the chain link of chain 5 can just be stuck in the cavity that forms between two plectrum 10c, is resisted against during chain 5 transmissions on this shifting part 10, makes the stable transmission of chain 5, can not take place to slide and skew.As another kind of scheme, shifting block 10b that also can above-mentioned shifting part 10 is set to axially protrude along cylindrical shell 10a, and shifting block 10b is resisted against on the chain link of chain 5 vertical directions, can prevent the slip and the skew of chain 5 equally.
As shown in Figure 1, also be connected with guide 11 in the body 1 of this chain-type strainer, have installing hole 11a and two chain cylindrical void 11b that communicate with installing hole 11a of running through on the guide 11, two chain cylindrical void 11b lay respectively at the place, both sides of installing hole 11a, guide 11 is socketed on the shifting part 10 by installing hole 11a, and it is concentric with rotating shaft 6, chain 5 passes in the chain cylindrical void 11b and walks around shifting part 10 backs and passes by another chain cylindrical void 11b, the chain link shifting block 10b ruly all the time and on the shifting part 10 of chain 5 is matched, thereby can not cause the slip and the torsiversion malposition of chain 5.
The rotating shaft 6 of this chain-type strainer is made up of two axis body 6a that are semicircle shape, all offer the axis hole 8a that is complementary with it on above-mentioned shifting part 10 and the ratchet 8, two semi-circular axis body 6a are located in the axis hole 8a, make that rotating shaft 6 and shifting part 10 are circumferentially fixing, and rotating shaft 6 is concentric with shifting part 10.Simultaneously be close to the connecting hole 6b that body 1 place offers two correspondences respectively, and two alignment pin 6c are set are located in the connecting hole 6b, prevent that axis body 6a from moving axially two semicircle axis body 6a both sides.
As depicted in figs. 1 and 2, offer pilot hole one 1a on the body 1 of this chain-type strainer, be used for installing retaining tooth plate 3, retaining tooth plate 3 self has elastic mechanism, therefore when ratchet 8 rotates, retaining tooth plate 3 can slide on the ratchet 8b of ratchet 8 and be embedded in all the time between the ratchet 8b, makes rotating shaft 6 one-directional rotation.Offer pilot hole two 2a that are used for 4 guiding of shaking hands on the handle 2, handle 4 self has elastic mechanism, and handle 4 can be embedded between the ratchet 8b of ratchet 8.When handle 4 is embedded between the ratchet 8b, thereby can drive rotating shaft 6 rotations towards a direction turning handle 2 chain 5 is tightened up, with handle 2 backward rotation, handle 4 slips over ratchet 8b, rotating shaft 6 is because the effect of retaining tooth plate 3 maintains static, and therefore needing only reciprocal turning handle 2 can tighten up chain 5.
Embodiment two
The structural principle of the structural principle of embodiment two and embodiment one is basic identical, and different places are: in this chain-type strainer, the shifting block 10b of shifting part 10 is the driving lever that is shaft-like, and driving lever can be embedded in the chain link of chain 5.Being similar to the meshing relation of gear and chain, just matches with driving lever in the hole when chain 5 transmissions between the chain link, thereby smooth transition when chain 5 is rotated around shifting part 10 can not slided.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
