Abstract

The utility model relates to a binding tightener, which comprises a frame body (1), a ratchet shaft (2), a clamp spring (3), a pawl (4), a torsion spring (5) and a pin shaft (6), wherein the ratchet shaft (2) is rotatably arranged on end arms (11 and 12) of the frame body (1) and is axially arranged on the frame body (1) by the clamp spring (3) in a clamping way; the part of the ratchet shaft (2), which is positioned between the end arms (11 and 12), is provided with a cylindrical steel wire rope winding segment (21); the pawl (4) is articulated with the frame body (1) by the pin shaft (6) and is meshed with a ratchet (22) arranged on the ratchet shaft (2); the torsion spring (5) is sleeved on the pin shaft (6); and one end of the torsion spring (5) is connected with the frame body (1) in a clamping way, and the other end of the torsion spring (5) is connected with the pawl (4) in a clamping way so that the pawl (4) is reset. The binding tightener has the advantages that the breaking tension is bigger, the structure is simple, the manufacturing cost is low, and the use is more economic and more convenient. In addition, the forged integral frame body structure is firmer, and the constituent parts of the whole tightener are fewer, therefore, the installation is more convenient.

Description

The binding fastener

Technical field

The utility model relates to fastener, and fastener is tied up in the rope coil that is specifically related to be used in a kind of railway freight to bundle timber.

Background technology

It is fastening to need to use steel rope to carry out in the railway freight log loading process, to guarantee the safety of lumber Transporting.The binding fastener is in the process of binding timber, to tighten up steel rope, though passed through continuous renewal and improvement, still exists rupture pull force big inadequately; The complex structure cost is high; Use uneconomically, use shortcomings such as convenient inadequately, can't satisfy the needs of railway freight.In order to ensure safety of railway transportation, existing binding fastener still need continue to improve.

Summary of the invention

The purpose of the utility model provide bigger, the simple in structure cost of a kind of rupture pull force low, use more economically, use and bundle fastener more easily.

The technical solution of the utility model is: it comprises U-shaped framework, ratchet shaft, jump ring, ratchet, torsion spring and bearing pin; The two ends of ratchet shaft be rotatably installed on two of the framework end arms and through jump ring axially be installed on the framework, the part of ratchet shaft between two end arms of framework be that cylindrical steel wire rope twines section; Ratchet is hinged on the framework through bearing pin and is meshed with ratchet on the ratchet shaft, and torsion spring set is contained on the bearing pin, the one of which end is connected on the framework, the other end is connected to ratchet is resetted.

The technique effect of the utility model is: it have bigger, the simple in structure cost of rupture pull force low, use more economically, use advantage more easily.The integral type frame structure of its cast structure is firmer, and whole fastener constituent elements still less installs convenient.Because cost is lower, disposable use is more economical, littler, the more compact structure of its volume; Be more convenient for storing and carrying, only need both can use, manipulate more convenient with the free wrench operation; Can also ratchet be locked with the ratchet stop pin after being fastened to required stroke, safety is guaranteed.

Description of drawings

Fig. 1 cuts open figure for the three-dimensional office of the utility model embodiment;

Fig. 2 is the utility model embodiment block diagram.

The specific embodiment

Like Fig. 1, shown in Figure 2; It comprises U-shaped framework 1, ratchet shaft 2, jump ring 3, ratchet 4, torsion spring 5 and bearing pin 6; The two ends of ratchet shaft 2 be rotatably installed on two of the framework 1

end arms

11,12 and through jump ring 3 axially be installed on the framework 1, ratchet shaft 2 is that cylindrical steel wire rope twines section 21 in two end arms 11 of framework 1, part between 12; Ratchet 4 is hinged on the framework 1 through bearing pin 6 and is meshed with ratchet 22 on the ratchet shaft 2, and torsion spring 5 is sleeved on the bearing pin 6, the one of which end is connected on the framework 1, the other end is connected to ratchet 4 is resetted.

Framework 1 is provided with ratchet lock pin holes 13.Be respectively equipped with the ratchet

shaft mounting hole

14,15 of coaxial line on the two

ends arm

11,12 of framework 1; The framework 1 end arm that ratchet 4 is installed is provided with and ratchet

shaft mounting hole

14,15 homoaxial bearing pin mounting hole 16 and torsion spring blocked holes 17, and ratchet lock pin holes 13 and bearing pin mounting hole 16 be coaxial to be located on the end arm that framework 1 is provided with bearing pin mounting hole 16.Ratchet shaft 2 is that an end is provided with the cylindrical body that ratchet 23, other end outer wall are provided with jump ring groove 24, are axially arranged with square tommy bar through hole 25 along ratchet 23.Be provided with between tommy bar through hole 25 ports of 1 two of

frameworks end arm

11,2 outer walls of the ratchet shaft between 12 and ratchet end and favour the axial steel rope through hole 26 of ratchet shaft 2.Bearing pin 6 is riveted on the framework 1.

One end of steel rope passes U-lag between framework 1 and the ratchet shaft 2, connects into rope sling through gland and be enclosed within on the framework 1 during use; The other end of steel rope penetrates ratchet shaft 2 and passes from the tommy bar through hole 25 of ratchet end from the steel rope through hole 26 on the outer wall of ratchet shaft 2; The square toes of tommy bar are inserted the tommy bar through hole 25 switching ratchet shafts 2 of the ratchet other end; The steel rope that the binding steel rope promptly can be wrapped in ratchet shaft 2 twines to rein in to be pressed on the ratchet shaft 2 on the section 21 and with its termination realizes self-tightening; When the degree of tension of binding steel rope reaches requirement, going into ratchet lock pin holes 13 with the riveting of ratchet stop pin can pin ratchet 4, bundlees fastening completion.The disposable use of binding fastener is to guarantee its safety in utilization.
