The tool-free regulating structure disclosed by the utility model carries out regulation without using other tools in the whole process, and has the characteristics of simple structure and convenience in use.
Description
Technical field
The utility model relates to a kind of electric chain saw chain, particularly a kind of instrument of exempting from regulation structure of electric chain saw chain tension degree.
Background technique
In the middle of the use of electric chain saw, because chain can be along with the use expansion of generating heat, and it is lax to cause in use chain to produce, and, generally in use for some time, need to regulate the rate of tension of chain for this reason.
At present, the regulation structure of chain tension degree as shown in Figure 1, its mainly comprise adjusting screw 1 ' and moving sheet 2 ', wherein adjusting screw 1 ' afterbody be provided with straight groove 11 ', adjusting screw 1 ' head and moving sheet 2 ' be threaded, and moving sheet 2 ' link together with the similar bearing pin mode of carrier bar of locating chain, when needs are regulated, need by straight screwdriver or special tool rotate adjusting screw 1 ', and by adjusting screw 1 ' rotation drive moving sheet 2 ' movement, and then the carrier bar of drive and moving sheet 2 ' link together moves, and realizes the adjusting of chain tension degree.At this, because needing other instruments for public use, whole adjustment process carries out, and not only troublesome poeration has also brought very large inconvenience to use.
The model utility content
For the problems referred to above, the utility model has designed a kind of instrument of exempting from regulation structure of electric chain saw chain tension degree, and its whole adjustment process can not carried out by other instruments, has characteristics simple to operate, easy to use.
For achieving the above object, the utility model is by the following technical solutions:
A kind of instrument of exempting from regulation structure of electric chain saw chain tension degree, comprise an adjusting screw and one and the moving sheet that links together of carrier bar, described adjusting screw head is threaded with moving sheet, it is characterized in that: described regulation structure also comprises a knob assembly, whole knob assembly comprises adjusting screw, adjustment ring, small gear and a worm screw, wherein the degree of tightness of adjusting knob can determine that whether adjustment ring rotate, adjustment ring inside is provided with adjusting gear and is connected with pinion, the coaxial connection of an end of small gear and worm screw, the other end of worm screw and described adjusting screw afterbody are in transmission connection by worm gear pair.
Further, on adjustment ring, under original state, adjusting knob is pressed on the adjustment ring above-mentioned adjusting knob by snaps into position, and adjustment ring can't be rotated, and only adjustment ring can be rotated after adjusting knob unscrews.
In use, unscrew adjusting knob, thereby adjustment ring can be rotated, and the rotation of adjustment ring sequentially drives adjusting gear, small gear and turbine rod rotation, and then realize that by the worm gear pair transmission of turbine rod and adjusting screw adjusting screw rotates, and drive moving sheet by the rotation of adjusting screw and move, and then the adjusting of realization chain tension degree is moved in drive with the carrier bar that moving sheet links together.
The whole Adjustment operation of the utility model need not by other or special tool, and the instrument of having realized exempting from is regulated, and can directly rotate adjustment ring with hand and get final product, and is simple to operate, very easy to use.
At this, rotate adjustment ring for avoiding misoperation occurring, described adjusting knob is connected with the adjustment ring buckle, integral body is positioned on the protecting cover, and under general state, adjusting knob is pressed on the adjustment ring, adjustment ring is limited in the middle of adjusting knob and the protecting cover, this moment adjustment ring can't rotate, and only after unscrewing adjusting knob adjustment ring just can rotate, just can carry out the adjusting of chain tension degree.
Description of drawings
The perspective exploded view of Fig. 1, existing chain tension degree regulation structure;
Fig. 2, stereochemical structure decomposing schematic representation of the present utility model;
Partial sectional view after Fig. 3, the utility model assembling.
Embodiment
Shown in Fig. 2 and 3, a kind of instrument of exempting from regulation structure of electric chain saw chain tension degree comprises an adjusting screw 1 and one and the moving sheet 2 that links together of carrier bar, and described adjusting screw 1 head is threaded with moving sheet 2.
Described regulation structure also comprises a knob assembly, whole knob assembly comprises adjusting knob 31, adjustment ring 32, small gear 33 and a worm screw 34, wherein the degree of tightness of adjusting knob 31 can determine whether adjustment ring 32 can rotate, adjustment ring 32 inside are provided with adjusting gear 321 and are connected with a joggle with small gear 33, the coaxial connection of an end of small gear 33 and worm screw 34, the other end of worm screw 34 and described adjusting screw 1 afterbody are in transmission connection by worm gear pair 341.
In use, unscrew adjusting knob 31 and adjustment ring 32 is rotated, and the rotation of adjustment ring 32 sequentially drives adjusting gear 321, small gear 33 and turbine rod 34 rotations, and then by worm gear pair 341 transmissions realization adjusting screw 1 rotation of turbine rod 34 with adjusting screw 1, and drive moving sheet 2 by the rotation of adjusting screw 1 and move, and then the carrier bar that drive and moving sheet 2 link together moves, and realizes the adjusting of chain tension degree.
Above whole Adjustment operation need not by other instruments or special tool, and the instrument of having realized exempting from is regulated, and can directly rotate adjustment ring 32 with hand and get final product, and is simple to operate, very easy to use.
At this, rotate adjustment ring 32 for avoiding misoperation occurring, described adjusting knob 31 is connected with adjustment ring 32 by buckle, both integral body are positioned on the protecting cover 4, under general state, adjusting knob 31 is pressed on adjustment ring 32 on the protecting cover 4, and this moment, adjustment ring 32 can't be rotated, and only unscrewing the rotatable adjustment ring 32 of adjusting knob 31 rear, just can carry out the adjusting of chain tension degree.
The above, it only is better embodiment of the present utility model, be not that any pro forma restriction is done in invention, every foundation know-why of the present invention still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations or modification that above embodiment does.
