Description

A kind of multi-functional bar hook

Technical field

Present invention design belongs to mechanical field, but contacts closely with Construction of Civil Engineering, is a kind of multi-functional bar hook.

Background technology

The process of binding of reinforcing bar must be used steel reinforcement hook. Steel reinforcement hook on the market mainly has two kinds: one is that handle is rotary; Another kind is that handle is non-rotatable. The application of rotating steel reinforcement hook is relatively extensive. When the non-rotatable steel reinforcement hook of handle is due to use, finger directly bears the static friction of handle, on the one hand that the injury of palm finger is big, effort during use on the other hand. And the steel reinforcement hook of rotatable handles there is also a lot of drawback, inefficiency.

Summary of the invention

Present invention solves the technical problem that and be, it is possible to improving the steel reinforcement hook of work efficiency, specific position can be carried out reinforcing bar binding by rotational by steel reinforcement hook.

The content solving the technical program is that a kind of multi-functional bar hook includes metal handle and the rubber protecting jacket being enclosed within metal handle; Described swivel becket is located at metal handle front end, and outer metal arm is connected on metal handle by swivel becket, and outer metal arm can relatively rotate ring and rotate, and outer metal arm is enclosed within interior metal arm, and interior metal arm can move by external metal arm mutually; Described outer metal arm and described interior metal arm are provided with scale; Interior metal arm front end is provided with hook.

Further, interior metal arm front end and hook parallel position have installed measurement termination.

Further, rubber protecting jacket is enclosed within metal handle by ball bearing.

Further, stating swivel becket and include U-type groove and the rotating shaft through U-type groove, outer metal arm is provided with fixing hole, and outer metal arm is movably fixed in U-type groove by rotating shaft by fixing hole.

It is an advantage of the invention that interior metal arm can mutually externally metal arm move, the stretching of metal arm and outer metal arm in realizing, when needing the length of change steel reinforcement hook, it is possible to carry out the adjustment of length by pulling interior metal arm; Interior metal arm with outer metal arm are carved with master scale, it is necessary to during measurement, it is possible to direct reading; By change swivel becket angle, it is possible to regulate outer metal arm and metal hand between angle; Rubber protecting jacket is waited in use and can be enclosed within above turning handle.

Interior metal arm front end and hook parallel position have installed measurement termination, during work, use the protective layer thickness measuring termination measurement reinforcing bar.

Rubber protecting jacket is enclosed within metal handle by ball bearing, and ball bearing plays the effect rotating metal handle. When user assembling reinforcement new for this this practicality, by turning handle, play the effect of colligation, simultaneously more laborsaving.

In figure, metal handle 1, rubber protecting jacket 2, swivel becket 3, outer metal arm 4, interior metal arm 5, measurement termination 6.

Detailed description of the invention

As shown in Figure 1, Figure 2, a kind of multi-functional bar hook includes metal handle 1 and the rubber protecting jacket 2 being enclosed within metal handle 1; Swivel becket 3 is located at metal handle 1 front end, and outer metal arm 4 is connected on metal handle 1 by swivel becket 3, and outer metal arm 4 can relatively rotate ring 3 and rotate. In Fig. 3, swivel becket 3 includes U-type groove and the rotating shaft through U-type groove, and outer metal arm 4 is provided with fixing hole, and outer metal arm 4 is movably fixed in U-type groove by fixing hole by rotating shaft, outer metal arm 4 is enclosed within interior metal arm 5, and interior metal arm 5 can move by external metal arm 4 mutually; Outer metal arm 4 is provided with scale with interior metal arm 5; Interior metal arm 5 front end is provided with hook.

Preferred in Fig. 4, interior metal arm 5 front end and hook parallel position have installed measurement termination 6, during work during colligation lower floor reinforcing bar, it is possible to measuring the distance between reinforcing bar and template by measuring termination 6, the protective layer thickness to verify reinforcing bar meets requirement.

Preferably, rubber protecting jacket 2 is enclosed within metal handle 1 by ball bearing.

Preferably, outer metal arm 4 is hollow metal rod, and interior metal arm 5 is solid bar member, and solid bar member can the bulk strength of reinforcing steel bar hook.

During work, in reinforcing bar binding process, it is necessary to the bar spacing of the bar-mat reinforcement or reinforcing steel bar cage of colligation is measured and adjusts, and it is very time-consuming individually to adjust bar spacing by steel ruler measurement, efficiency is very low, and workmen often simply substantially estimates to cause construction quality very poor. The present invention is by the outer metal arm 4 of steel reinforcement hook and interior metal arm 5 high scale, solving this problem very well. When reinforcing bar binding, it is necessary to when adjusting distance, directly measure with outer metal arm 4 and/or interior metal arm 5, convenience and high-efficiency.

Outer metal arm 4 can relative in metal arm 5 move (telescopic arm), it is possible to solve very well bar-mat reinforcement or the construction of the closeer i.e. reinforcing bar binding that manual operation space is only small of reinforcing steel bar cage, such as the colligation of some deep beam reinforcing steel bar cage. Existing steel reinforcement hook forearm is not long, it is impossible to the colligation to deep beam bottom reinforcement bars well, and it is very poor that the colligation work major part bottom therefore is done.

Regulate the angle between outer metal arm 4 and metal handle 1 by swivel becket 3, it is possible to play 3 effects: 1, change and rotate the arm of force, meet the instructions for use of different strength user. 2, when constructing closeer bar-mat reinforcement, regulate smaller angle, make slewing area less, affected by bar-mat reinforcement little time movable, convenient construction. When 3, increasing angle, increase the arm of force, more laborsaving when making rotation.

Rubber protecting jacket 2 on metal handle 1 can protect finger and palm very well. Going up steel reinforcement hook used on the market and compare the hands that rubs, even if putting on one's gloves use, glove use the time not long. Rubber protecting jacket 2 can alleviate the friction of finger palm and handle, reduces the use of construction glove, saves engineering cost.
