Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Figure 1-3, embodiments of the present invention are related to a kind of vehicle-mounted child restraint system test tool coiler,
Including bracket and main shaft 5,5 level of main shaft is erected on bracket, and one end of the main shaft 5 passes through bearing 4 and 1 phase of worm gear
Even, the upper end cross of the worm gear 1 staggeredly engages and is disposed with worm shaft 2, and the side of the worm gear 1 is axially extended along main shaft 5
There is connecting plate 12, one end of the connecting plate 12, which is vertically equipped with, is flexibly connected column 3, and one end of the flexible connection column 3 is inserted radially into
Into 5 one end of main shaft, the other end of the main shaft 5 is equipped with handle I 6, one end of handle II15 and worm shaft 2 by along
Two radially arranged the screw 16 of worm shaft 2 is connected and fixed, and the middle part of the main shaft 5 is disposed with safety belt around socket part 13.
It as a kind of embodiment of the invention, uses Worm and worm-wheel gearing as regulating mechanism, carries out in two steps:
First, under belt slack state, it is flexibly connected column 3 and is not inserted into main shaft 5, the transmission mechanism and main shaft 5 of such worm and gear
Separation not will drive the rotation of main shaft 5, and by safety belt solderless wrapped connection in safety belt in socket part 13, handle I 6 can faster will be safe
Band is wrapped on main shaft 5, so that " disadvantage " that overcomes worm gear transmission ratio excessive, improves winding efficiency；Second, safety belt is opened
Begin to be flexibly connected column 3 after tensioning and move down, be inserted into 5 hole of main shaft, so that worm gear mechanism is connect with main shaft 5, worm gear
Main shaft 5 can be driven to rotate, at this time rotating handle II15, so that it may be fine-tuned.
Further supplementary explanation, the bracket includes bottom plate 10 and riser I 8 and riser that bottom plate both ends are arranged vertically
The both ends symmetric transverse stretching of II9, the riser I 8 are equipped with side plate 7, and the main shaft 5 sequentially passes through riser I 8 and riser
II9 is simultaneously connected by bearing 4 with riser I 8 and riser II9, and the worm shaft 2 passes through two side plates 7 and arranges, using this knot
Structure can firmly fix worm shaft 2 and main shaft 5, and reserve bigger space to solderless wrapped connection safety belt on main shaft 5.
Further, the flexible connection column 3 is wing bolt, and the threaded portion of lower end and 12 screw thread of connecting plate connect
It connecing, the structure of wing bolt, which conveniently turns, is flexibly connected column 3, and make its axial movement, is inserted into the unthreaded hole of 5 one end of main shaft, this
When sample wing bolt is detached from from main shaft, can still it rest on connecting plate.
Further, the end face outside of the riser I 8 and riser II9 are equipped with the bearing (ball) cover to match with bearing 4
11, bearing 4 is limited, disassembly, the assembling of device are also facilitated.
Further, it is socketed with axle sleeve 17 on the main shaft 5 between the worm gear 1 and riser I 8, the both ends of the axle sleeve 17
It is axially withstood with bearing 4, axle sleeve 17 keeps the position of main shaft 5 reasonable, and engaging with worm shaft 2 will not be interfered by other structures.
Further, the both ends of the worm shaft 2, which are located at, is socketed with Horizontal axle on the outside of side plate 7 and holds seat 14, by horizontal
Bearing block 14 carrys out supporting worm axis 2, and intensity is big, and the rotation of worm shaft 2 is also smoother smooth.
Further, the end that the handle I 6 passes through two axially arranged screw 16 and main shaft 5 along main shaft 5
It is connected, is connected firmly, power transmission is stablized.
The configuration of the present invention is simple is reasonable, easy to operate, using the self-locking property of worm and gear, realizes " step-less adjustment ", into
And the tension adjustment time is saved, the accuracy of tension adjustment is improved, to improve test efficiency and testing crew ability.
