Abstract
The utility model discloses an electric binding wire hook with the overload protection function. The electric binding wire hook with the overload protection function comprises a shell, a motor and a binding wire hook body, wherein the motor is located in the shell, part of the binding wire hook body is located in the shell, a first toothed disc is fixedly installed on the binding wire hook body, a second toothed disc is fixedly installed on an output shaft of the motor, the first toothed disc is meshed with the second toothed disc, and a spring is arranged between the inner wall of the shell and the first toothed disc. The output shaft of the motor transmits movement to the binding wire hook body through the first toothed disc and the second toothed disc which are meshed with each other, a binding wire is tightly screwed and binds steel bars firmly, if the binding wire on the binding wire hook reaches the screwing limitation, resistance borne by the binding wire hook increases, the binding wire hook almost stops rotating, at this moment, the output shaft of the motor still rotates, the first toothed disc and the second toothed disc slip due to overloads, the rotation of the motor cannot be transmitted to the binding wire hook, and the binding wire stops being screwed before being about to be broken, so that the binding wire is not prone to being broken, production cost is saved, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of building implement, is specifically related to a kind of electronic tied silk hook with overload protection.
Background technology
Tying up of reinforcing bar is all often to adopt tied silk, and will use reinforced bar fasten yarn hook during with tied silk wiretie, thereby reinforced bar fasten yarn hook is as a kind of special tool, is widely used on building site.Existing its structure of reinforced bar fasten yarn hook is that one end is handle mostly, and the other end is forniciform tip composition, by the hook-shaped position on tip, catches on tied silk, rotates reinforced bar fasten yarn hook, and tied silk can be firm by reinforced-bar binding.In traditional method, concrete reinforcement worker adopts the colligation of tied silk hook manpower, and labour intensity is large, and the hand of holding tied silk hook repeats same action repeatedly, and workman's fatiguability, affects efficiency.For overcoming this defect, in prior art, also there is the motor of employing to drive tied silk hook, the utility model that is 201320064881.4 as application number discloses a kind of tied silk automatic binding device, comprise tied silk hook, described tied silk hook is located at external shell one end, in described external shell, be provided with motor and chip board, described motor is provided with tied silk hook, and described chip board is provided with motor.This tied silk automatic binding device has replaced traditional manual colligation by electric machine rotation tied silk hook, accelerate colligation speed, reduce constructor's labour intensity, also improved the efficiency of construction of reinforced bar binding wire binding simultaneously, but motor direct-drive tied silk hook rotates, the number of turns turning over along with tied silk is more, the load that motor consumes is larger, and between motor and tied silk hook without adjusting device, thereby very easily colligation of tied silk firmly under situation motor also in rotation, tied silk is also twisted several circles under the limiting case of tightening, thereby tied silk is very easily twisted into two parts, affect manufacturing cost, working time and operating efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic tied silk hook with overload protection.
For achieving the above object, the technical solution of the utility model is:
A kind of electronic tied silk hook with overload protection; the motor and the part that comprise housing, are positioned at housing are positioned at the tied silk hook of housing; it is characterized in that: the second fluted disc on the output shaft that also comprise the first fluted disc of being fixedly installed on tied silk hook, is fixedly installed in motor; the first fluted disc and the second fluted disc are intermeshing, between the inwall of housing and the first fluted disc, are evenly equipped with some springs.
Further, output shaft is provided with brake gear, and housing is provided with the switch of controlling brake gear.
The beneficial effects of the utility model are:
1, the output shaft of motor passes motion to tied silk hook by intermeshing the first fluted disc and the second fluted disc, tighten tied silk reinforcing bar binding is firm, if the tied silk on tied silk hook reaches the limit of tightening, the suffered resistance of tied silk hook increases and almost stops operating, and now the output shaft of motor still rotates, because making the first fluted disc and the second fluted disc, overload there is skidding, rotatablely moving of motor cannot be passed to tied silk hook, tied silk was stopping tightening before being twisted into two parts, tied silk is not easily broken, save cost of production, improved operating efficiency; And drive tied silk hook to replace traditional manual colligation by motor, accelerated colligation speed, reduced constructor's labour intensity, improved the efficiency of construction of reinforced bar binding wire binding, the utility model scope of application is wide.
2, output shaft is provided with brake gear, and in the time that skidding appears in the first fluted disc and the second fluted disc, output shaft is still rotating, press the switch on housing, brake gear is braked output shaft, has reduced two wearing and tearing that fluted disc skids and causes because of overload, thereby has improved its application life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of electronic tied silk hook with overload protection, comprises housing 1, tied silk hook 3 and motor 2.Part tied silk hook 3, through the hole on housing 1, makes its part be positioned at housing 1, and another part is positioned at outside housing 1, and tied silk hook 3 can be around its axis rotation, and the tied silk hook 3 that is positioned at housing 1 is fixedly connected with the first fluted disc 6.Motor 2 is fixedly installed in housing 1, is fixedly connected with second fluted disc 7 suitable with the first fluted disc 6 on the output shaft 5 of motor 2, coils for the first time 6 and engages with the second fluted disc 7.Between the inwall of housing 1 and the first fluted disc 6, be evenly equipped with some springs 4, in order to make spring 4 fixations, can on the inwall of housing 1 and the first fluted disc 7, offer groove or the hole of locating for spring 4.
When the utility model work, the output shaft of motor passes motion to tied silk hook by intermeshing the first fluted disc and the second fluted disc, and the rotation of tied silk hook, on reinforcing bar, makes reinforcing bar binding firm tied silk colligation; After reinforcing bar binding is firm, tightening tied silk needs larger power, before tied silk is about to be twisted into two parts, spring cannot provide enough large elastic force, overload causes the first fluted disc and the second fluted disc to start to skid, and the output shaft of motor cannot pass motion to tied silk hook, thereby tied silk is difficult for being twisted into two parts.The present embodiment can be by selecting the spring of different stiffness factors, adjusts the active force of the first fluted disc to the second fluted disc, thereby transmit different power, is applicable to the different tied silk of various screwing forces.
In addition, also can between tied silk hook 3 and the output shaft 5 of motor 2, speed changer be set, the angle turning over by the adjustable tied silk hook 3 of speed changer, makes tied silk not easily broken.The output shaft 5 of motor 2 is provided with brake gear 12, and housing 1 is provided with the switch 11 of controlling brake gear 12.In the time that output shaft 4 separates with tied silk hook 3, output shaft 4 is still rotating, now push switch 11, and brake gear 12 is braked output shaft 5.
