Abstract

The utility model relates to a universal torque amplification device, particularly a manual tool which can be arranged on a socket wrench, or an elevator and is convenient, labor saving and rapid to screw bolts and nuts, and the universal torque amplification device has one multiple functions. The utility model is composed of an input gear system and an output gear system which are arranged in a casing. Input gears and output gears are coaxial gears, and are engaged with intermediate gears. Shafts of the input gears and output gears are respectively input and output shafts simultaneously. The utility model has the advantages of simple structure, few parts, small size and convenient carrying, and is especially suitable for being carried in the field and operation in the air. The torque amplification device works in a forward direction, and the purpose of labor saving can be reached; the torque amplification device works in a reversal direction, and the screwing is fast to save time. The gears are universal gears. The utility model has the advantages of strong versatility, easy fabrication, low cost and remarkable boosting effect.

Description

General booster

The utility model relates to a kind of booster of hand-operated tools, particularly not only can be at box spanner, but also can use on bottle opener.Can make things convenient for, dismantle or screw fast effortlessly the general booster of bolt, nut.

Employed step-up system on existing Strong Wrench or the multi-functional bottle opener, all function singleness there is no versatility.And structure is complicated, Heavy Weight, portably use all inconvenient.

The patent No. 94200544.9 " railway ash pillow labour-saving spanner " provides a kind of labour-saving spanner that is used for dismounting railway track nut, but only is confined to use on spanner.

The purpose of this utility model is to provide a kind of general booster, both can be installed on the box spanner, can be installed on the bottle opener again and use, and can make things convenient for, the labour-saving screws off or screw bolt, screw fast, and it is simple in structure, in light weight, portably use conveniently.

The utility model is achieved in that general booster is made up of the input, the output gear train that are installed in the housing.And import, output gear is in-line gears, and with idler gear engagement, its axle is respectively power shaft, output shaft simultaneously.

Fig. 1. structural representation of the present utility model (no handle)

Fig. 2. the right view of Fig. 1 (band handle).

Fig. 3. make spanner user mode figure.

Fig. 4. make bottle opener user mode figure.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Output gear (1) mid portion has square shaft output shaft (3) square, shape the region between the heart and the diaphragm hole, garden for and two ends vertical with the increment face, and the number of teeth is 45.

Input gear (2) mid portion has square the region between the heart and the diaphragm hole for a vertical end with the increment face, and an end does not have the square shaft power shaft (4) in the region between the heart and the diaphragm hole, and the number of teeth is 18.

Housing (7) upper end is a side opening, and the rectangular cavities of through hole is arranged on the side, and the lower end is the transition petioliform of band screw.

Handle (8) is a circular bar shape, is fixed in the screw of housing (7) lower end.

Idler gear is that duplicate gear (6) is embedded on housing (7) madial wall.

The no the region between the heart and the diaphragm nose end and the integrant in-line gears of output gear (1) garden shape the region between the heart and the diaphragm nose end loose fit of input gear (2) mesh with duplicate gear (6) respectively in the housing of packing into (7), cover cover plate (5) again, and are connected into whole booster with four screws.

If when its booster as box spanner is used, as shown in Figure 3, only need original ratchet handle is contained in booster power shaft (4) end, box spanner directly is contained in the sleeve that various different sizes were held or refilled by extension bar earlier to booster output shaft (3), just sleeve approach is used routinely, and reinforcement effect is 1-6.25 times.

If need screw nut fast, at this moment only need ratchet handle is contained in output shaft (3) end of booster, and the extension bar of former box spanner is contained in booster power shaft (4) end, just can reach quick time saving effect, quicken loading and unloading and save time 1-6.25 doubly.

Use if this booster will be installed on the bottle opener, at this moment only need that handle and swing arm with bottle opener inserts respectively, in the square hole on output shaft (3) or the power shaft (4), booster and bottle opener are fused, just can use work, reach the purpose of reinforcement and Jie Shi simultaneously as normal bottle opener.

If will move nut, bolt than high pulling torque, the handle (8) of housing (7) lower end can be supported on the ground or on the basis, so just can free hand to move nut, bolt, reduce labor intensity.

The utility model is compared with prior art: because input, the output gear of booster is in-line gears, and Be respectively simultaneously power shaft, output shaft, so part is few, simple in structure, compact, volume is little, be convenient to take Band, use is carried in especially suitable field work and work high above the ground. It both can forward work make reinforcement Device uses and to reach the labour-saving purpose, again can reverse operation, and screw fast and make time saver and use and reach when saving Between purpose. Because of its adopt for common general gear, the technology highly versatile, easily to process cost low, dark Be subjected to car mechanic's favor. Because reinforcement effect is remarkable, can avoid the operator at mounting or dismounting high pulling torque nut, Must use the drawback of very long boosting-rod during bolt, for the operating personnel that goes out provides more easily instrument. This booster both can use at spanner, can use at bottle opener again, realized one-object-many-purposes. A kind of fine Universal practical booster.
