Abstract

This creation is about a kind of "wrench socket", which is used for the rotation of a ratchet wrench insert set. The wrench socket has a cylinder body that can be sleeved on the outer edge of a rotating part. The inner wall of the cylinder body is spaced apart. There are a plurality of first latching parts and second latching parts. The first latching part is located between the two second latching parts. The feature of this creation is that the first latching part is curved and convex. The two latching parts have an oblique straight surface, and the position where one end of the oblique straight surface extends and the inner wall of the barrel has an inner concave arc, and one end of the oblique straight surface forms an acute angle toward the center of the barrel. The oblique direction of the straight face must allow the ratchet wrench to rotate in a predetermined direction so that the outer edge of the rotating member can at least abut the oblique straight face and the first latching portion, so that the structure can be lifted down before the preset degree is retained. Reduce the abrasion of the barrel and increase the service life.

Description

Wrench socket

This creation is related to a wrench socket, especially an innovative structure revealer that reduces wear and slippage and extends service life.

By the way, it is quite common for nuts to be used as fixed parts in various mechanisms or products. For hexagonal nuts, most users will use a spanner to engage and move in order to save effort and convenience. With the advancement of the times, in order to solve the problem of inconvenience of carrying traditional wrenches, various socket tools of various sizes have been developed, which can combine the functions of conventional wrenches and the advantages of portability.

Most of the conventional sleeve structures set the assembly hole as a hexagonal hole. However, because this kind of sleeve can only be used with a hexagonal nut, the applicable size of the wrench is also limited, so the convenience is still not ideal, and there are habits. It is known that although the inner wall design of the sleeve makes the hexagonal nut somewhat pre-determined when rotating and fitting, it can be adapted to different sizes or different nut outer edges, but it is still easy to wear due to the pre-determination during reciprocating rotation, which will not only reduce The life of the sleeve itself will also damage the outer edge of the nut, so it will cause problems such as the wrench cannot be driven or easily loosened, so further improvement is necessary.

In view of this, the creator has many years of experience in the production and sales of related products, and in view of the current related problems, he pondered the improvement methods. After many improvements and tests, he finally got an innovative structure.

For this reason, the main purpose of this creation is to overcome the shortcomings of the conventional structure, such as easy wear and slippage and short service life, to provide a wrench socket that can be rotated and used with a ratchet wrench insert set. The wrench socket has a barrel. The body can be sleeved on the outer edge of a rotating member. The inner wall of the barrel is provided with a plurality of first and second latching portions. The first latching portion is located between the two second latching portions It is characterized in that a center is defined in the sleeve, the first locking portion is arc convex, the second locking portion has an inclined straight surface, one end of the inclined straight surface extends and the inner wall of the barrel There is an inner concave arc at the joint position, forming an acute angle at one end of the oblique straight surface towards the center of the circle, and the oblique direction of the oblique straight surface must allow the ratchet wrench to rotate in a predetermined direction so that the outer edge of the wrench can at least abut The oblique face and the first latch part.

The following is a further description with the drawings of the preferred embodiment of this creation, in order to enable those who are familiar with the related technology of this creation to implement it according to the statements in this specification.

First of all, please refer to Figure 1 and Figure 2. This is an implementation type in different directions. For limitations, please also refer to Figures 1 to 7. The wrench socket 05 disclosed in this creation is used for the rotation of a ratchet wrench (not shown). The wrench socket 05 has a barrel 10, It can be sleeved on the outer edge of a rotating part A (such as a hexagonal nut or a nut of other outer edge types in Figures 6 and 7, this part is not limited), and the inner wall of the barrel 10 is provided with a plurality of first The detent part 20 and the second detent part 30, the first detent part 20 is located between the two second detent parts 30, and is characterized in that:

The sleeve defines a center C (only shown in Figures 1 and 2), the first locking portion 20 is arc convex, the second locking portion 30 has an inclined straight surface 31, the inclined straight surface The position where one end of the extension 31 meets the inner wall of the barrel 10 has an inner concave arc 32, which forms an acute angle toward the center C of the inclined straight surface 31, and the inclined direction of the inclined straight surface 31 must be used for the ratchet 06 When the hand rotates in a predetermined direction, the outer edge of the rotating member A can at least abut the inclined straight surface 31 and the first latching portion 20. Take the rotating member A as a hexagonal nut as an example, as shown in Figures 4 and 5 As shown, the barrel 10 is sleeved on the rotating member A under normal conditions so that the outer edge of the rotating member A and the inclined direction of the inclined straight surface 31 have an angle θ. When the barrel 10 rotates in a direction of disassembly, the When the angle θ becomes larger or smaller, the barrel 10 of this embodiment is turned in the forward assembly direction to reduce the angle θ. On the contrary, when the barrel 10 moves in the reverse disassembly direction, the angle θ becomes larger (not shown) ), at this time, the outer edge of the rotating member A can at least abut the inclined straight surface 31 and the first latching portion 20, so the inclined straight surface 31 can improve the stability of the latching, and the first latching portion 20 can provide auxiliary latching , Even when the acute angle of the inclined straight surface 31 gradually wears, it does not directly wear the inclined straight surface 31, but can make the latch more stable. Therefore, compared with the conventional structure, this creation can overcome the conventional structure easy to wear and slip, It has short service life and other shortcomings, and there is no problem of ratchet wrench loosening, so it has the advantages of improving product service life and continuous stability.

As shown in Fig. 3, in the practice of this creation, the first and second latching parts 20, 30 define an inner concave wall 40, and the inclined straight surface 31 and the inner concave wall 40 are arranged in the same plane as the interval. In addition, the inner concave wall 40 defines a first width W1, the inclined straight surface 31 defines a second width W2, and the second width W2 must exceed at least one third of the first width W1.

For those skilled in the art, various other corresponding changes and deformations can be made based on the technical solutions and assumptions described above, and all these changes and deformations should fall within the protection scope of the creative claims.
