Abstract
The utility model provides a laborsaving spanner, by box spanner part, reinforcement slewing mechanism, supporting shoe, power unit and casing are constituteed, and wherein reinforcement drive mechanism comprises two-stage worm wheel power transmission part and the straight-teeth gear transmission part that is located the casing, and the box spanner part is installed on the integral key shaft, and when it passed the power partial time with the worm wheel, it can make the light nut of screwing up or unscrewing of box spanner, when it was transmitted by gear transmission part, can install soon or lift the nut off, the utility model discloses specially adapted loading and unloading automobile tire or the nut or the bolt of other equipment have small, light in weight, the characteristics of laborsaving operation, can be used as the vehicle-mounted tool.
Description
The utility model relates to a kind of instrument that nut, bolt are used that loads and unloads, and particularly a kind ofly is used to load and unload the nut of doughnut or miscellaneous equipment or the labour-saving spanner of bolt.
The bigger nut or the pine of bolt are unloaded or are fastening, need bigger torsional moment could realize that the nut of the doughnut of removing stage makeup and costume at present or bolt use box spanner mostly, use very effort.Also useful electronic charging crane loading and unloading nut, but electronic charging crane volume weight is all big, can only contraposition load and unload, and can't load and unload the nut that is positioned at than narrow positions, because electric power is big, can not carry with car.Retrieval by patent documentation, finding and having application number in the prior art is that 88203540.1 doughnut labour-saving spanner and application number are two patents of labour-saving spanner of 89206767.5, they all adopt the planetary gear speed-reduction principle to realize boosting function, but the loading and unloading of loosening back are very slow, time-consuming.
The purpose of this utility model is to provide a kind of and is easy to carry, can make driver's tool, can ten to hundred times of loading and unloading labour-saving spanners that also can unload nut or bolt fast of reinforcement.
The purpose of this utility model is to realize by such structure, and promptly it is by box spanner, force-increasing mechanism, and back-up block and actuating unit are formed; It is characterized in that the energizing driver structure is by forming for two-stage spiral shell worm and gear power transmission in housing part and spur gear rotating part, wherein worm screw (4) is the rotating shaft of actuating unit, one termination power source, the other end is fixed with spur gear (3), and cooperate with worm gear (6), cooperate with worm gear (8) with the worm screw (7) of worm gear (6) rotating shaft one, worm gear (8) is enclosed within splined shaft (9) one ends, when splined shaft backward during displacement, both splines connect, spur gear (10) is connected with the splined shaft spline, and mesh with gear (3), the other end of splined shaft is with compression spring (11), and box spanner (12) is installed, and back-up block (1) is fixed on the housing with the box spanner homonymy.
Said structure of the present utility model can be further detailed by accompanying drawing.
Accompanying drawing 1 is the manual structural representation of the utility model;
Referring to Fig. 1, unloading or during fastening nut (bolt), at first selecting fit on being unloaded the box spanner (12) that nut (13) adapts.A downward then repoussage device makes spring (11) compression, and the splined section of splined shaft this moment (9) enters in the splined hole of worm gear (8), when shaking rocking-turn bar (5) gently when applying power, worm screw (4) transmission worm gear (6); Worm gear (6) is coaxial with worm screw (7), and the rotation that makes worm screw (7) is by driving worm gear (8), and makes box spanner twist nut (13) by splined shaft (9).Because the power that is added on the rocking-turn bar (5) is amplified through the transmission of two-stage worm and gear, can make box spanner obtain to have increased the power of ten times even hundred times, thereby can turn nut very easily, after in case nut is loosening, then can remove pressure to spring (11), it is resetted, at this moment the splined section on the splined shaft (9) withdraws from worm gear (8) and enters in the splined hole of gear (10), shake rocking-turn bar (5), by gear (3) direct drive gear (10), and by floral axis drive splined shaft (9), can soon loosening nut be unloaded, the process of dress nut is opposite with the process of loosening nut.
Referring to Fig. 2, for more laborsaving, fractional electric motor (14) can be installed, and the coaxial drive of its power output shaft worm screw (4) is rotated in the position of manual rocking-turn bar (5).
In above-mentioned two legends, the twisting resistance when back-up block (1) is resisted operation as fulcrum.Its strong point can be selected or regulate as required.Housing (2) but dimidiation make of accurate cast steel.The standard socket wrench (12) of splined shaft (9) end assembling can have all size, uses for you to choose.Rocking-turn bar (5) among Fig. 1 but folding so that carry.
Compare with prior art, laborsaving saving time when the utility model advantage is use, compact conformation, volume is little, and is in light weight, is easy to carry, and can be used as driver's tool.
The utility model is applicable to the loading and unloading of big shape nut (bolt), is specially adapted to the dismounting of automobile tire and the installation and removal of assembling and other main equipment.
Claims (3)
1, a kind of loading and unloading labour-saving spanner, by box spanner part (12), the energizing driver structure, back-up block (1), actuating unit and housing (2) are formed; It is characterized in that the reinforcement rotating mechanism is made up of two-stage Worm and Worm Gear Driving power part that is positioned at housing and spur gear running part, wherein worm screw (4) is the power transmission shaft of actuating unit, one termination power source, the other end is fixed with spur gear (3), and cooperate with worm gear (6), cooperate with worm gear (8) with the worm screw (7) of worm gear (6) rotating shaft one, worm gear (8) is enclosed within on splined shaft one end, when splined shaft backward during displacement, both splines connect, and spur gear (10) is connected with the splined shaft spline, and meshes with gear (3), the other end of splined shaft is with compression spring (11), and installing sleeve spanner (12); Back-up block (1) is fixed on the housing with the box spanner homonymy.
2, labour-saving spanner according to claim 1 is characterized in that a end that worm screw (4) connects power source is connected with rocking-turn bar (5) and constitutes manual power mechanism.
3, labour-saving spanner according to claim 1 is characterized in that worm screw (4) connects the power output shaft of a termination fractional electric motor (14) of power source.
