Abstract
The utility model relates to a worm and gear wrench for mounting and demounting bolts in small spaces, and belongs to the technical field of tools. A bolt clamping structure integrated with a worm gear is arranged below the worm gear and comprises a rotary disc with a plane thread on one side face and three clamping jaws. The rotary disc is fixed on a hollow center column of the bolt clamping structure through a third bearing, and the three clamping jaws are mounted on the plane thread in an equant manner. The outer surface of each clamping jaw is higher than the end face of the bolt clamping structure. The diameter of the rotary disc 7 is smaller than that of the periphery of the bolt clamping structure. Three openings are formed in positions, corresponding to the rotary disc, on the periphery of the bolt clamping structure. The openings are located among the three clamping jaws equidistantly. A worm is fixed on a housing through a first bearing and a second bearing, the head of the worm is meshed with the worm gear, and a handle is arranged at the tail of the worm. A fixing sleeve is arranged at the position close to the handle, and the worm can rotate in the fixing sleeve. The worm and gear wrench has the advantages of small size and simple structure, and is particularly suitable for mounting and demounting the bolts in the small and narrow spaces, and the shortcoming that an existing wrench is inconvenient to operate in small and narrow working spaces is overcome.
Description
Technical field
The utility model relates to assembling-disassembling bolt worm and gear spanner in a kind of little space, belongs to technical field of tools.
Background technology
The position allowed for space, all can be used monkey wrench or fork spanner during the installation or removal bolt.Yet, when narrow space, use monkey wrench or fork spanner will be inconvenient to operate.When usually dismounting is positioned at the bolt of small space, a kind of method is first to lay down external shell and then by disassembling bolts; Another kind method be with screwdriver sled, hammer knock, the methods such as electric drill destroys bolt are disassembling bolts, the bolt then more renewed.Above two kinds of modes are mainly the spatial limitation that screws that is subject to bolt, can't left and right firmly or the bolt turned be not enough to carry out chucking next time, such method not only wastes time and energy, efficiency is very low, and also may damage equipment in disassembly process, cause economic loss.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides assembling-disassembling bolt worm and gear spanner in a kind of little space.
Assembling-disassembling bolt worm and gear spanner in a kind of little space, worm gear is fixed on the below of sheath body by the 4th bearing, and there is the bolt card locking structure with the worm gear one worm gear below; The bolt card locking structure comprises that there are rolling disc and three claws of flat thread a side; Rolling disc is fixed on by the 3rd bearing on the hollow center post of bolt card locking structure, and three claw deciles are arranged on flat thread; The claw outer surface is higher than the clamping structure end face; Rolling disc 7 diameters are less than the clamping structure peripheral diameter, and the peripheral place of the clamping structure corresponding with rolling disc offers three openings; Opening is equidistantly between three claws; Worm screw is fixed on sheath body by clutch shaft bearing and the second bearing; Worm screw head and worm gear engagement, afterbody has handle; Place near handle is provided with fixed cover, and worm screw can be rotated in fixed cover.
The utility model has the advantages that volume is small and exquisite, simple in structure, be specially adapted to the bolt in the dismounting small space, overcome the drawback that existing spanner is not easy to operation when working space is narrow and small.And can greatly increase work efficiency.Spanner uses worm and gear as drive mechanism, has increased moment, can be laborsaving during use.The similar scroll chuck of bolt card locking structure, can be applicable to different big or small bolts, has the use popularity.
The accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, Figure 2, Figure 3 shows, the worm and gear spanner of assembling-disassembling bolt in a kind of little space, sheath body 1 reaches fixedly Worm and worm-wheel gearing for sealing.Worm gear 2 is fixed on the below of sheath body 1 by bearing 12, there is the bolt card locking structure 5 with the worm gear one worm gear 2 belows; The scroll chuck structure of using on bolt card locking structure 5 and lathe is similar, and it comprises that there are rolling disc 7 and three claws 6 of flat thread 9 side; Rolling disc 7 is fixed on by bearing 10 on the hollow center post of bolt card locking structure 5, and three claw 6 deciles are arranged on flat thread 9; Claw 6 outer surfaces are higher than the clamping structure end face, for clamping three faces of hex bolts; Rolling disc 7 diameters are slightly less than the clamping structure peripheral diameter, and the clamping structure 5 peripheral place corresponding with rolling disc offers three openings 8; Opening is equidistantly between three claws 6, and openings of sizes is advisable to be applicable to stirring rolling disc with finger; When stirring rolling disc 7, the flat thread 9 at its back side just make three claws 6 simultaneously to center near or exit, applicable to the bolts of different sizes;
During use, first according to the size of bolt, stir three faces that rolling disc 7 makes claw 6 clamping bolts.A fixed cover 11 held on worm screw again, another hand turning handle 4, by the transmission mechanism of worm and gear, the revolving force that will be positioned at perpendicular is converted to the rotation of horizontal plane, realizes tightening or loosening the function of bolt.
As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
