Description
Technical field
The utility model relates to a kind of strainer for restraint of loads, particularly relates to a kind of automatic belt retracted tensioning device.
Background technology
Strainer, as a kind of binding tools, is widely used, in use, because bundling belt is long, cause take-up loaded down with trivial details, binding is sturdy not, and binding efficiency is low, for above problem, application number is 201220625601.8, and the applying date is 2012.11.22, and name is called, and " a kind of shaking strainer " has solved above problem, the utility model provides a kind of shaking strainer, belongs to field of mechanical technique.It solve existing strainer complicated operation, bundle inefficient problem.It comprises support, tape spool and handle, support takes the shape of the letter U, and tape spool is positioned at support and the two ends of tape spool are axially fixed in the both sides of U-shaped support respectively, and tape spool is fixed with worm gear, on support, axial restraint has the worm screw be meshed with worm gear, and handle is connected in worm end and handle is in tape spool sidepiece.This shaking strainer has that stability in use is high, simple to operate, practical value advantages of higher.But this shaking strainer is owing to being manual take-up, and take-up is still more loaded down with trivial details, binding efficiency is also lower.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide the automatic belt retracted tensioning device that a kind of take-up is easy, binding is sturdy, binding efficiency is high.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of automatic belt retracted tensioning device, comprise support, rocking arm and plastic casing, described support comprises bracket shell, clockwork spring, main shaft, ratchet and gear baffle, described support is connected with plastic casing by rivet, and described rocking arm is connected with support.
Further, described bracket shell side edge is along being provided with spacing draw-in groove, this bracket shell bottom surface is provided with circular hole, this bracket shell sidewall is provided with through hole and axis hole, described gear baffle is connected with bracket shell by through hole, described main shaft is connected with bracket shell by axis hole, is provided with clockwork spring shell outside described clockwork spring, and this clockwork spring shell is connected by M4 screw with bracket shell.
Further, described main shaft is provided with plastic jacket, gear bush and jump ring, and this main shaft and ratchet socket-connect, and this main shaft is connected with reinforcement elastical cloth one end, and this reinforcement elastical cloth other end is connected with hook.
Further, described rocking arm is provided with dead bolt, and on this dead bolt, cover has latch bolt spring.
Further, described plastic casing is provided with band outlet and circular hole, and this circular hole is corresponding with the circular hole of bracket shell.
Compared with prior art, the utility model has the advantage of: the utility model enables the utility model automatic band-retracting and self-locking by the design of ratchet, dead bolt and gear baffle, take-up is easy, binding is sturdy, binding efficiency is high, and this product design is reasonable, is applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is inner structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1-2, a kind of automatic belt retracted tensioning device, comprise support 1, rocking arm 2 and plastic casing 3, described support 1 comprises bracket shell 4, clockwork spring 5, main shaft 6, ratchet 7 and gear baffle 8, on this main shaft 6, cover has plastic jacket and gear bush, ratchet 7 is socketed in main shaft 6 two ends, main shaft 6 is connected with reinforcement elastical cloth one end, the other end strengthening elastical cloth is connected with hook 9, main shaft 6 socket-connects with the axis hole on bracket shell 4 two side, jump ring is stuck on main shaft 6, restriction main shaft 6 left and right displacement, described clockwork spring 5 is connected with main shaft, when tensile strength elastical cloth, clockwork spring 5 meeting energy storage, when take-up, clockwork spring 5 can shrink, reach the object of automatic band-retracting, the clockwork spring shell of protection clockwork spring 5 is provided with outside clockwork spring 5, clockwork spring shell is fixed on outside bracket shell 4 by M4 screw, this bracket shell 4 sidewall is provided with through hole, gear baffle 8 is connected with bracket shell by through hole, gear baffle 8 is connected with retracing spring one end, the retracing spring other end is connected with rocking arm 2, the angular adjustment of the flexible meeting driven gear baffle plate 8 of retracing spring, bracket shell side edge is along being provided with spacing draw-in groove, bracket shell 4 bottom surface and plastic casing 3 bottom surface are equipped with screw and circular hole, bracket shell 4 is connected through screw by rivet with plastic casing 3, bracket shell 4 just in time aligns with the circular hole of plastic casing 3 bottom surface, when bundling hook and not fixing stuck point, hook 9 can be fixed through circular hole, plastic casing 3 is provided with band outlet, hook 9 and reinforcement elastical cloth can pull out from band outlet, rocking arm 2 is connected with support 1, dead bolt 10 and latch bolt spring is provided with in this rocking arm.
In using, rocking arm 2 of holding with a firm grip, presses dead bolt to spring direction, dead bolt is separated with ratchet 7, hook 9 is pulled outwardly with reinforcement elastical cloth, clockwork spring 5 energy storage, after binding, decontrol rocking arm 2, ratchet 7 blocks by dead bolt, strengthen elastical cloth can only contract and can not draw, clockwork spring 5 shrinks exoergic, strengthens elastical cloth and shrinks, when strengthening elastical cloth and tightening, rocking arm 2 is upwards rotated, further tighten, retracing spring driven gear baffle plate 8 changes angle, and gear baffle 8 blocks ratchet 7, completes take-up.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
