Description

Technical Field

[0001] The utility model relates to the technical field of ratchet handles, and particularly relates to a multi - multiple two - way ratchet handle. Background Technique

[0002] Ratchet handles are mainly divided into one - way and two - way types. The one - way type is reversed by pulling out and then inserting it in the opposite direction, and the two - way type adjusts the rotation direction of the ratchet through an external paddle. Their main purpose is to enable the force - bearing body to rotate continuously without the operator repeatedly pulling out. For the current ratchet handles, if the force - bearing body rotates one week, the ratchet handle also needs to rotate one week.

[0003] For the existing one - way ratchet handle, it needs to be pulled out and then inserted in the opposite direction for commutation; while the two - way handle adjusts the rotation direction through an external paddle. However, if the force - bearing body rotates one circle, the ratchet handle also needs to rotate one circle, and the rotation efficiency cannot be improved. Therefore, there is an urgent need for a multi - multiple two - way ratchet handle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi - multiple two - way ratchet handle to solve the problems raised in the above background technique.

[0005] To solve the above - mentioned technical problems, the utility model provides the following technical solution: A multi - multiple two - way ratchet handle, including a handle and a sun gear. A rotation hole is opened on the handle, and the back surface of the sun gear is rotatably arranged in the rotation hole. A planetary gear set is rotatably arranged inside the handle, a ring gear is arranged outside the planetary gear set, two limit blocks are rotatably arranged on the inner side of the handle, two compression springs are fixedly connected to the inner side of the handle, a rotating block is rotatably arranged inside the handle, and the back surface of the rotating block movably penetrates through the handle and is fixedly connected to a paddle.

[0006] Preferably, the planetary gear set is composed of multiple small planetary gears, and the multiple small planetary gears are respectively meshed with the sun gear.

[0007] The planetary gear is composed of multiple small planetary gears. The more the number of small planetary gears, the greater the transmission ratio between the ring gear and the sun gear. And each small planetary gear can only rotate around its own center and cannot revolve around the center of the sun gear.

[0008] Preferably, the ring gear and the sun gear are concentrically arranged, and the internal teeth of the ring gear are meshed with the planetary gear set.

[0009] Preferably, the two limit blocks are symmetrically arranged, and one ends of the two limit blocks are respectively fixedly connected to the compression springs.

[0010] The outer teeth of the gear ring are restricted by the limit block, so the gear ring can only rotate in one direction. When the gear ring needs to change direction, the paddle is used to drive the rotating block to rotate. The rotating block rotates through the limit block on one side to release the limit block on the other side, thereby completing the reversal. The limit block on the released side can be reset by setting the compression spring.

[0011] Preferably, the rotating block is located between two limiting blocks, and one end of the rotating block is in conflict with the limiting blocks.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] First, the utility model adds a planetary gear set inside the handle to improve the speed ratio. When the ring gear rotates one circle, the sun gear in the middle can rotate multiple circles, thereby improving the use efficiency of the tool.

[0014] Second, in the utility model, when the gear ring needs to be reversed, the paddle is turned to drive the rotating block to rotate, and the rotating block rotates through the limit block on one side to release the limit block on the other side, thereby completing the reversal, so that the reversal can be conveniently performed without pulling out the handle.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides the following technical solutions:

[0022] Embodiment 1

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A multiple bidirectional ratchet handle comprises a handle 1 and a sun gear 4. A rotating hole is opened on the handle 1. The back of the sun gear 4 is rotatably arranged in the rotating hole. A planetary gear set 3 is rotatably arranged inside the handle 1. A gear ring 2 is arranged on the outer side of the planetary gear set 3. Two limit blocks 5 are rotatably arranged inside the handle 1. Two compression springs 6 are fixedly connected to the inner side of the handle 1. A rotating block 7 is rotatably arranged inside the handle 1. The back of the rotating block 7 movably passes through the handle 1 and is fixedly connected to a paddle 8.

[0024] The planetary gear set 3 is composed of a plurality of small planetary gears, and the plurality of small planetary gears are respectively meshed with the sun gear 4 .

[0025] The ring gear 2 and the sun gear 4 are arranged concentrically, and the internal teeth of the ring gear 2 mesh with the planetary gear set 3 .

[0026] The two limit blocks 5 are symmetrically arranged, and one end of the two limit blocks 5 is fixedly connected to the compression spring 6 respectively.

[0027] The rotating block 7 is located between the two limiting blocks 5 , and one end of the rotating block 7 is in conflict with the limiting block 5 .

[0028] Through the above technical solution, the ring gear 2 and the sun gear 4 are concentric and can rotate freely, and the planetary gear is composed of a plurality of small planetary gears. The more small planetary gears there are, the greater the transmission ratio between the ring gear 2 and the sun gear 4 is. Each small planetary gear can only rotate around its own center of circle and cannot revolve around the sun gear 4. The planetary gear set 3 is meshed with the inner teeth of the ring gear 2 and the sun gear 4 at the same time. When the ring gear 2 rotates with the handle 1, the ring gear 2 drives the planetary gear set 3 to rotate, and the planetary gear set 3 drives the sun gear 4 to rotate. , and the outer teeth of the gear ring 2 are limited by the limit block 5, so the gear ring 2 can only rotate in one direction. When the gear ring 2 needs to change direction, the rotating block 7 is driven to rotate by toggling the paddle 8, and the rotating block 7 rotates through the limit block 5 on one side to release the limit block 5 on the other side, thereby completing the reversal. When reversing, the limit block 5 on the released side can be reset by setting the compression spring 6; the ratio of the number of internal teeth of the gear ring 2 to the number of teeth of the sun gear 4 is the transmission ratio of this ratchet handle, that is, when the handle 1 rotates one circle, the sun gear 4 can rotate multiple circles.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the invention is defined by the appended claims and their equivalents.
