Utility model content
The purpose of this utility model is to provide a kind of lift rotation reinforcing steel bar binding hook, and this reinforcing steel bar binding hook uses light and handy, and fast power-saving, can reduce the labour intensity of operating personnel, enhance productivity.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of lift rotation reinforcing steel bar binding hook, it is characterized in that: it comprises gib head and carrying handle, described carrying handle is tubular structure, and its inside is provided with screw rod; Described screw rod only the latter half is provided with spiral salient, and the bottom of screw rod is fixedly connected with gib head, and upper end is provided with end plate; Described carrying handle bosom place is provided with annular boss, and on described screw rod, also cover has back-moving spring, and described back-moving spring is between annular boss and end plate; The inwall of described carrying handle lower end is provided with axial notch, is provided with non-return block in notch, the lower end of non-return block and the lower end of notch hinged, be provided with elastic device between non-return block top and notch; When screw rod moves downward, the upper end of non-return block is against the soffit of spiral salient, and when screw rod moves upward, spiral salient heads on non-return block and draws close to carrying handle.
Described elastic device is spring leaf, and the upper end of spring leaf is fixed on the upper end of notch, and lower end contacts with non-return block.
Described non-return block upper end is provided with movable ball.
Described gib head and screw rod adopt screwed connection.
The beneficial effects of the utility model are:
1, the utility model pulls carrying handle that gib head one direction can be made to rotate, the good reinforcing bar of fast binding, and use light and handy, fast power-saving, can reduce the labour intensity of operating personnel, enhance productivity; And after carrying handle pulls, the body of rod extends, and operating personnel, when colligation floor bar, avoid operation of squatting down for a long time, cause the overtired situation of soreness of waist and ache in legs;
2, the elastic device in the utility model is spring leaf, uses the advantage that spring leaf has volume little and stable;
3, in the utility model, non-return block upper end is provided with movable ball, and ball contacts with spiral salient, makes the rotation of screw rod more smooth;
4, gib head described in the utility model and screw rod adopt screwed connection, change to split.

Detailed description of the invention
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further.
As Figure 1-5, a kind of lift rotation reinforcing steel bar binding hook, it comprises gib head 1 and carrying handle 2, and described carrying handle 2 is tubular structure, and the external diameter that its inside is provided with the upper spiral salient 4 of screw rod 3 described in screw rod 3(should coincide with the internal diameter of carrying handle 2); Only the latter half is provided with spiral salient 4(the first half to described screw rod 3 is cylinder), the bottom of screw rod 3 is fixedly connected with gib head 1, and upper end is provided with end plate 9; The internal diameter that described carrying handle 2 bosom place is provided with annular boss 7(annular boss 7 should be greater than the external diameter of screw rod 3 body, be less than the external diameter of spiral salient 4), on described screw rod 3, also cover has back-moving spring 8, and described back-moving spring 8 is (back-moving spring 8 should be in compressive state all the time) between annular boss 7 and end plate 9; The inwall of described carrying handle 2 lower end is provided with axial notch, and (preferred notch is a pair, and be positioned at the two ends of same diameter), non-return block 5 is provided with in notch, the lower end of non-return block 5 and the lower end of notch hinged, be provided with elastic device (elastic device against non-return block 5 to carrying handle 2 axe movement) between non-return block 5 top and notch; When screw rod 3 moves downward, the upper end of non-return block 5 is against the soffit of spiral salient 4, and when screw rod 3 moves upward, spiral salient 4 heads on non-return block 5 and draws close to carrying handle 2.
Described elastic device is spring leaf 6, and the upper end of spring leaf 6 is fixed on the upper end of notch, and lower end contacts with non-return block 5.
Described non-return block 5 upper end is provided with movable ball (ball contacts with spiral salient 4).
Described gib head 1 adopts screwed connection with screw rod 3.
Described screw rod 3 is provided with screw mandrel, spiral salient 4, the cylinder body of rod and end plate 9 from top to bottom successively.Spiral salient 4 engages with non-return block 5, and the spin canting that spiral salient 4 is formed, under non-return block 5 nibbles thrust, produces turning effect.
The upper end of preferred described non-return block 5 is oblique, engages with spiral salient 4.
Use principle of the present utility model: described spring leaf 6 struts non-return block 5, makes non-return block 5 engage with spiral salient 4, and when pulling carrying handle 2, screw rod 3 rotates; When screw rod 3 resets under the effect of back-moving spring 8, non-return block 5 contacts with the outer rim of spiral salient 4, makes non-return block 5 return in the notch of carrying handle 2, and screw rod 3 straight line rises; Finally realize screw rod 3 single direction rotation.
Using method of the present utility model: first gib head 1 is caught on tied silk, then pull carrying handle 2, screw rod 3 rotates, thus drives coupler body 1 to be tightened by tied silk turn-knob, carrying handle 2 self-return under the effect of back-moving spring 8.
More than illustrate and be only Application Example of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
