Description

Ratchet wrench structure

The invention relates to a ratchet wrench structure, in particular to a ratchet wrench structure which has two kinds of rotating structures: normal rotation and strong clamping. The two kinds of rotating structures are switchable, and the strong card is rotated. The integral circumferential surfaces are engaged, and thus have a larger area of mutual engagement, so that the ratchet wrench structure of the present invention can withstand the use of a stronger clamping state with greater torque.

As previously known to us, the conventional ratchet wrench structure, such as US Patent Application No. 12/944028, publication number: 2012/0118112, Taiwan Patent Application No.: 099220898, certificate number: M402762, patent name: ratchet wrench limit device The patented structure is: a ratchet wrench limiting device, which mainly comprises: a wrench head having a wrench handle connected to the rear end thereof, and a front end portion provided with a placement portion for the D head and a ratchet hole, and a placing portion The rear end is provided with a matching receiving groove, and a through hole is dug downward in the receiving groove, and a bottom groove is formed in the bottom of the through hole; a limiting device is installed in the through hole of the wrench head; The utility model mainly has a card abutting block, and a column body extends below the card abutting block, and a hole is arranged in the middle portion of the column body, a spring is arranged in the hole groove, and a cap column is sheathed at the outer end of the spring. And a ring groove is further dug in the column below the cap column, and a ring-shaped groove device is coupled to the C-shaped buckle device; a D-head is mounted on the placement portion of the wrench head and the ratchet hole. And the outer edge of the cover sheet has a missing portion of the array; The lower pressure limiting device positions the card abutting block in the accommodating groove, and restricts the rotation of the D head, and further pushes the card abutting block out of the accommodating groove by pushing up the limiting device, thereby releasing the cover piece of the D head, Make the ratchet wrench perform the swivel operation, which is characterized by By.

The main advantage of the conventional ratchet wrench structure limiting device is that the locking member 31 is positioned in the receiving groove 15 by the pressing and lowering device 30, thereby restricting the rotation of the D head 20 and pushing the lifting limit. The bit device 30 has its card abutting block 31 out of the receiving groove 15, thereby releasing the cover sheet 21 of the D head 20, and causing the ratchet wrench to perform a swinging operation. For this feature, the ratchet wrench has two kinds of rotating structures in operation. That is to say, it has two kinds of rotating structures, such as normal rotation and strong clamping, and the operation is more expandable.

However, the lack of structure of this patent is based on:

1. In addition, as shown in FIG. 1 , FIG. 2 and FIG. 4 of the U.S. Gazette or the Taiwan Gazette, the latching block 31 of the retaining device 30 of the ratchet wrench limiting device is received in the receiving slot 15 . When the latching block 31 is fastened to the missing portion 22 of the cover sheet 21, the rotation of the D head 20 is restricted, that is, the wrench head 12 is rotated to the latching portion 21 and the missing portion 22 of the cover sheet 21. The D head is rotated, but the carding area between the card abutting block 31 and the missing portion 22 is small, and the area of the missing portion 22 is shown by the first figure and the second figure, so that the large rotating torque cannot be withstood. .

2. The D head 20 is rotated in the ratchet hole 14 of the wrench head 12, but when the card is strongly clamped, the missing portion 22 may not necessarily be aligned with the card abutting block 31, and the D head 20 is also sleeved. When the cylinder and the screwing member are in the assembled state, the D head 20 is limited to the screwing member, and the screwing member is limited to the screw hole, and the D head 20 is in a state of being unable to rotate naturally, and the state occurs. The probability is quite high, so that the D head 20 needs to be disengaged from the screwing member first, and the D head 20 can naturally rotate to make the missing portion 22 and the card abutting block 31 align, and the operation is not smooth.

In view of the lack of the above-mentioned conventional patented ratchet wrench limit device, the inventors have years of experience in related industries, and finally have a product that can solve the drawbacks of the ratchet wrench structure.

Use a ratchet with normal rotation and strong rotation The wrench can not bear a large rotating torque when the power is rotated. The ratchet wrench structure of the invention has two kinds of rotating structures: normal rotation and strong clamping. The two kinds of rotating structures can be switched and operated, and the power card is powerful. When the system is rotated, the integral circumferential surface is engaged, and thus the larger area is engaged with each other, so that the ratchet wrench structure of the present invention can withstand the use of a strong clamping state with a larger torque.

A ratchet wrench structure, comprising: a book The system is provided with a first receiving groove, a second receiving groove, a ring gear portion and a first ring groove; a ratchet wheel is pivotally disposed in the first receiving groove, and the outer peripheral edge of the ratchet wheel is provided with a ratchet portion of the annular arrangement tooth, The ratcheting system is provided with a second ring groove and a third ring groove; a toothing is arranged in the second receiving groove, and the front side of the toothing is provided with a plurality of engaging teeth, and the engaging tooth system meshes with the ratchet portion of the ratchet a first buckle ring is disposed in the third ring groove, the first buckle ring is abutted against the end surface of the body; a second buckle ring is received in the second ring groove of the ratchet wheel, the second buckle ring The first ring groove is opposite to the third ring groove, and the first buckle ring is engaged with the first ring groove and the third ring groove to locate the ratchet, the ring tooth. The part is meshed with the ratchet part. The system directly rotates the ratchet, and the body and the ratchet reach a strong clamping state.

The ratchet wrench structure of the invention exhibits a normal swirling shape In the state, the system rotates the teeth and rotates the ratchet, that is, the rotation mode with a ratcheting effect. When the user moves the ratchet displacement, the ring tooth portion of the body meshes with the ratchet portion of the ratchet. The system directly rotates the ratchet, thus forming a strong carding rotation, so that the ratchet wrench structure of the present invention has two switching and rotating structures. When the ratchet wrench structure of the present invention is strongly clamped, the ring tooth portion of the body is engaged with the ratchet portion of the ratchet wheel, so that the overall circumferential area of the body and the ratchet are meshed with each other, and the ratchet wrench structure of the present invention can be Withstand greater torque and achieve the purpose of strong carding. When the normal rotation state is to be switched to the strong card state, or the strong card is used When the state is switched to the proper rotation state, only two kinds of rotation states can be switched by moving the ratchet, and the operation is quite convenient, and the operation is quite convenient. When the ratchet and the screwing member are in a state of being engaged in a state of normal rotation, if the ratchet and the screwing member are in a state of being engaged, the ratchet is limited to the screwing member and cannot be naturally rotated, although the ring tooth portion is When the teeth of the ratchet portion are not aligned, the ring teeth are arranged in an annular shape and are looped on the inner circumferential surface of the first pocket of the body, and the ratchet does not need to be separated from the screwing member, and only needs to be When the rotating body is at a very small angle, the ring teeth are easily engaged with the ratchet portion, and the operation is smoother.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
