Description
Technical field
The invention belongs to hardware & tools technical field, for being fixedly connected with of strip or rod shape crossing area, be particularly suitable for tying up of cross wise reinforcement, be specially the convenient wiretie pincers of a kind of hand-held.
Background technology
In construction, relatively more conventional is reinforced concrete structure.In the process of construction, need first to build framework of steel reinforcement with reinforcing bar, then pour into a mould; Usual way is that the manual reinforcing bar knotting to intersecting of bar bender's iron wire and vice is fixing.And we know, the fixing of reinforcing bar is not needed to bear very large power, just one common spacing, place misplace of rebars, be convenient to moulding by casting.
After improvement, at present when carrying out wiretie, the instrument adopted is generally a common crotch instrument, common crotch instrument had both needed workpeople to possess the technology of consummate wiretie, also to repeatedly to turn-take the reinforcing bar making the iron wire of wiretie bundle right-angled intersection, long working can make workpeople feel very tired out, and bring a lot of inconvenience to workpeople, efficiency is not high yet then.
Also there is special binding reinforcing bars equipment now, but mostly huger, and manual flexibility is inadequate; And the cost of unit is also higher; The maintenance maintenance in later stage is more difficult.
By retrieval, there is following existing patent:
Patent 1: China Patent No. CN200720059148.8, applying date 2007.10.30, publication date 2008.09.03, disclose a kind of reinforcing-bar binding machine, the reinforcing-bar binding machine tied up will be intersected at the reinforcing bar arranged in length and breadth of scene, construction site with wire, specifically provide a kind of reinforcing steel strapping machine wire coil brake, comprise the latch hook being installed in drum flange radial outside in drum storehouse, latch hook draw-gear, latch hook returning device, its difference is, described latch hook draw-gear forms by the torsion spring be installed on lock hook shaft and with torsion spring one section of haulage gear be connected, described latch hook returning device is made up of the return spring be installed on lock hook shaft.Owing to have employed spring buffer formula brake apparatus, the braking procedure of whole drum is all in buffer status, noiseless, and structure is simple, reliable operation, and meanwhile, because total coefficient of friction is little, what extend drum reuses number of times.
Patent 2: China Patent No. CN200910203087.1, applying date 2009.05.19, open (bulletin) day 2009.11.25, disclose a kind of reinforcing-bar binding machine, possess: the master collet (11) that hook (10) are housed at front end pivot, be entrenched in the front end axle (12) of the inside of above-mentioned master collet (11), be formed at the spiral helicine thread groove (14) of above-mentioned front end axle (12), inner chimeric opening (13) is penetrated into from the outside of above-mentioned master collet (11), be embedded in above-mentioned chimeric opening (13) and the key (15) engaged with above-mentioned thread groove (14), be located at the periphery of above-mentioned master collet (11) and cover the short sleeve (16) of above-mentioned key (15), be formed at above-mentioned short sleeve (16) and control the engaging unit (33 of the rotation of above-mentioned master collet (11), 34).
Patent 3: China Patent No. CN201010113610.4, applying date 2010.01.27, open (bulletin) day 2010.06.16, discloses a kind of reinforcing-bar binding machine, comprise frame, frame is provided with wire agency, winding mechanism, and wire agency comprises line sending arm, by line arm, line sending arm, lays respectively at work top both sides by line arm, and be respectively equipped with guide rail in it, be provided with line sending chain in guide rail, the head end of this line sending chain is provided with hook the end of a thread, line sending chain is connected with line sending drive unit; Winding mechanism comprises wire spool, and the side of this wire spool is provided with grab, and this grab is just to being subject to line arm; The opposite side of wire spool is provided with bobbin winding head, and this bobbin winding head is positioned at the rear side of line sending arm; Wire spool is also provided with for cutting off blade wiry at the rear side of bobbin winding head; Wire spool is connected with driver for winding.The present invention is rational in infrastructure, simple and clear, automatically by binding reinforcing bars together, can operate conveniently, be applicable to common laborer, can also work long hours and there will not be excessive line phenomenon, effectively raising operating efficiency, suitable for large-scale promotion.
In like product as above existing wiretie, mainly utilize machine simulation manually to tie up process wiry, realize being fixedly connected with of cross wise reinforcement.But the usual more complicated of the arrestment mechanism of wire drum, during use, not only noise is large, and poor reliability, have impact on the performance of complete machine greatly.And binding reinforcing bars tool construction is comparatively complicated, cost is higher, and glitch common laborer is difficult to maintenance, uses inconvenience.
Found by above retrieval, above technical scheme can not affect novelty of the present invention; And the mutual combination of above patent document can not destroy creativeness of the present invention.
