Detailed Description

As shown in fig. 1-4, a bolt dismounting device for increasing torque includes a casing 10, a sun gear 20 is provided in the casing 10, the sun gear 20 is engaged with and connected with a pinion 30, a gear ring 11 engaged with the pinion 30 is provided on an inner wall of the casing 10, dismounting components for dismounting or mounting fasteners are provided at two ends of the sun gear 20, the fasteners are used for fastening connection and are very widely applied, such as bolts and screws, through rotation of the casing 10, the gear ring 11 in the casing 10 sequentially drives the pinion 30 and the sun gear 20 to rotate, the number of the pinion 30 can be changed according to a proper gear scheme according to actual requirements, in this embodiment, the number of the pinion 30 is four, and four pinion 30 are arranged around the center gear 20, the sun gear 20, the pinion 30 and the gear ring 11 are always in an engaged state, the dismounting components at two ends of the sun gear 20 are sleeved on fasteners, such as bolts and nuts, and the casing 10 is rotated through the gear ring gear 11 and a plurality of the pinion 30 to drive the sun gear 20 to rotate, so that the torque is increased, and the purpose of saving labor can be achieved.

The sun gear 20 is provided with a sun gear shaft rotating synchronously therewith, the pinion gear 30 is provided with a pinion shaft 31 rotating relatively therewith, one end of the sun gear shaft is provided with a sleeve 21, the other end of the sun gear shaft is fixedly connected with a dismounting member 40, and the manners of fixedly connecting the sun gear shaft and the dismounting member 40 include, but are not limited to, the following manners: bonding, screwing, etc., the sleeve 21 is used for dismounting fasteners such as bolts, nuts, etc., the trepanning in the sleeve 21 may be hexagonal, quadrangular, etc., including but not limited to, it may be determined according to the shape of the nut of the fastener, whereas the dismounting member 40 is used for dismounting such as socket head cap screws, etc., the dismounting member 40 has a working end 42 below, the shape of the working end 42 is also various, and the fastener is dismounted through the working end 42.

The dismounting member 40 rotates relative to the casing 10, a plurality of first shaft holes 41 corresponding to the counter gear shafts 31 one by one are formed in the dismounting member 40, the casing 10 is provided with a top cover 50, a plurality of second shaft holes 51 corresponding to the counter gear shafts 31 one by one are formed in the top cover 50, through holes 52 are formed in the position, corresponding to the sleeve 21, of the top cover 50, the sleeve 21 is directly exposed through the through holes 52 of the top cover 50, and the dismounting member 40 rotates only when the counter gear 30 drives the sun gear 20 to rotate due to the fact that the counter gear 30 and the counter gear shafts 31 rotate relatively, namely, the counter gear 30 and the counter gear shafts 31 are in a non-linkage state, the counter gear 30 does not drive the counter gear shafts 31 to rotate.

The top cover 50 extends toward the dismounting member 40 to form a plurality of partition posts 53, and the partition posts 53 are sequentially arranged between two adjacent pinion gears 30, which is a simple structure, which is not described too much.

The shell 10 is fixedly connected with the handle 60, the shell 10 is convenient to rotate through the handle 60, the force application point is prolonged by the handle 60, the labor is saved when the fastener is detached according to the lever principle, and the handle 60 can be of an integral structure with the shell 10 or of a split structure.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the utility model, and that simple modifications and substitutions by those skilled in the art are within the scope of the utility model without departing from the spirit and scope of the utility model.
