A kind of bundled device controlling spool rotary freedom
Technical field:
The present invention relates to hardware & tools technical field, especially relate to a kind of binding apparatus.
Background technology:
Bundled device is extensive application in daily life, its pattern is varied, bundled device shown in Fig. 1 is one kind of, this bundled device comprises bundled device main body 90, is provided with principal series band 71 and the secondary frenulum 72 of band drag hook 80, wherein, described drag hook 80 totally in the figure of eight, comprises lacing connection ring 81 and shackle 82.
As shown in Figure 2, described bundled device main body 90 comprises base 92, the spool 91 be articulated on base 92, the ratchet 94 being fixedly mounted on spool 91 two ends, the spanner 93 be articulated on spool 91, principal series band 71 rear end winding is on the spool 91 of bundled device, and secondary frenulum 72 is fixedly connected with the crossbeam 921 of base 92.
Described base 92 is provided with the first elastic card 922, described spanner 93 is provided with the second elastic card 931, as shown in Figure 4, when spanner 93 swings back and forth around spool 91, second elastic card 931 snaps in ratchet 94 tooth, and driving pawl 94 rotates, and ratchet 94 drives spool 91 to rotate again, the spool 91 rotated tightens up principal series band 71, first elastic card 922 and snaps in ratchet 94 tooth to prevent ratchet 94 from turning round.
Bundled device described in Fig. 1 to Fig. 4, when unclamping the object that bundled device bundlees, the second elastic card 931 and the first elastic card 922 need to disengage with ratchet 94 simultaneously, and the rotary freedom of spool 91 is unrestricted.If the object that bundled device bundlees is heavier, or easily tumble, when the rotary freedom of spool 91 may be uncontrolled as runaway wild horse from being limited to change to suddenly unrestricted, tied object, may becoming at random quickly or injure operating personnel by a crashing object.In addition, if bundled device is when bundling object, the total length of principal series band 71 and secondary frenulum 72 is longer, and operating personnel continuously need swing back and forth spanner 93 to tighten up major-minor frenulum.
Summary of the invention:
Technical problem solved by the invention: the object that the bundled device described in Fig. 1 to Fig. 4 bundlees is heavier, or easily tumble, when binding object need be unclamped, namely when the second elastic card 931 and the first elastic card 922 disengage with ratchet 94 simultaneously, the rotary freedom of spool 91 is unrestricted, tied object may be uncontrolled as runaway wild horse, may become at random quickly or injure operating personnel by a crashing object; In addition, if bundled device is when bundling object, the total length of principal series band 71 and secondary frenulum 72 is longer, operating personnel continuously need swing back and forth spanner 93 to shrink the total length of principal series band and secondary frenulum, operation like this, the speed of shrinking principal series band and secondary frenulum total length is comparatively slow, and efficiency is lower.
The invention provides following technical scheme:
Control a bundled device for spool rotary freedom, comprise bundled device main body, be provided with the principal series band of band drag hook and secondary frenulum;
Described bundled device main body comprises base, spool, ratchet, spanner, described base and spanner are equipped with the articulated section of bilateral symmetry, described spool is articulated on the articulated section of base and spanner, base and spanner is made to form hinged relationship, described ratchet is fixedly mounted on spool, and ratchet is between the articulated section and the articulated section of spanner of base;
Described principal series band does not establish one end winding of drag hook on the spool of bundled device, and described secondary frenulum does not establish one end of drag hook to be fixedly connected with base;
Described base is provided with the first elastic card, and described spanner is provided with the second elastic card; When spanner swings back and forth around spool, the second elastic card snaps in the tooth of ratchet, and driving pawl rotates, and ratchet drives spool to rotate again, and the spool of rotation tightens up principal series band, and the first elastic card snaps in the tooth of ratchet to prevent ratchet from turning round;
One end of described spool is provided with extension, extension is fixed with dish type fastener, and described fastener circumferentially offers at least one buckle slot.
By technique scheme, the object that bundled device bundlees is heavier, or easily tumble, when unclamping above-mentioned object, second elastic card and the first elastic card need be in the state departed from hook tooth simultaneously, now, operating personnel can use the external key (this spanner is provided with the clamping part matched with buckle slot on fastener) coordinated with fastener to control the rotary speed of spool, so, tied object becomes controlled, and tied object can not become at random quickly or injure operating personnel by a crashing object.
In addition, if bundled device is when bundling object, the total length of principal series band and secondary frenulum is longer, and operating personnel can use said external spanner spinning reel to shrink the total length of principal series band and secondary frenulum, to improve the efficiency of shrinking principal series band and secondary frenulum total length.
Improve the one of technique scheme as the present invention, the articulated section of the bilateral symmetry of described spanner is positioned at the outside of the articulated section of the bilateral symmetry of base; The lateral wall of described spanner is provided with one group of fixture block, one group of fixture block is connected with rotating handles, described rotating handles comprises annular portion and handle portion, described spool through rotating handles annular portion and with its matched in clearance, the annular portion of described rotating handles is provided with at least one buckle protuberance, the quantity of buckle protuberance is identical with the quantity of buckle slot on fastener, and buckle protuberance can snap in the buckle slot of fastener.
By above-mentioned improvement, the present invention can get final product spinning reel by the rotating handles without external key in direct the present invention.Particularly, when bundled device need fast binding object or unclamp tied up object time, operating personnel can take off rotating handles from one group of fixture block, rotating handles is moved axially along spool, buckle protuberance on rotating handles is coordinated with the buckle slot of fastener, namely by rotating handles spinning reel, to tighten up principal series band or scaling principal series band.After operating personnel use rotating handles, rotating handles is connected on one group of fixture block, rotating handles is positioned on the lateral wall of spanner.Preferred as one, on described fastener, the quantity of buckle slot is two, and two buckle slots are symmetrical structure.
Illustrate the one of bundled device main body as the present invention, one end that described base is articulated with spool is provided with the first arcuate projection, described first arcuate projection is offered the bayonet socket that can coordinate with the second elastic card; Described spanner one end be articulated on spool is provided with and the first elastic card can be made to depart from the second arcuate projection engaged with hook tooth.When operating personnel need unclamp principal series band, stretch the second elastic card, makes it depart from the engaging with hook tooth, then along away from the direction rotary spanner of base, and operating personnel get loose the second elastic card, and the second elastic card snaps in the bayonet socket of the first arcuate projection; Meanwhile, the second arcuate projection makes the first elastic card depart from the engaging with hook tooth.So, the first elastic card and the second elastic card all depart from hook tooth and engage, and the rotation of spool is not by the first elastic card and the second flexible restriction, and principal series band can be loosened.
