The sleeve body is provided with a driving part and a wrenching part which is coaxially and integrally connected with the driving part. The outer peripheral surface of the driving part is provided with an annular groove. The elastic positioning body is in a form of c-shaped sheet and is provided with a top end, a bottom end is located at the opposite end of the top end, and a radial deformation part is connected between the top end and the bottom end. The radial deformation part can be elastically deformed in the radial direction when subjected to an external force. The top end and the bottom end of the elastic positioning body are latched in the annular groove of the sleeve body. The radial deformation part protrudes out of the annular groove, so that the effect of temporarily combining and positioning the existing socket wrenches can be achieved. The depth required by the annular groove can be reduced, and the overall strength and the service life are improved.

Description

Sleeve with elastic binding positioning

The present invention relates to a sleeve, and more specifically, it refers to a sleeve with elastic binding positioning.

As shown in the first figure, the sleeve 1 is mainly used as a turning connection interface between a socket wrench and an object to be turned (such as a hexagonal screw, etc.), and its outer cross section is hexagonal. However, in order to enable temporary joint positioning between the socket 1 and the socket wrench 9, the early socket 1 will open a number of notches 2 at the end corners of its outer peripheral surface, and set the socket 1 on the socket wrench 9 A C-shaped retaining ring 8 is provided on the inner peripheral wall of the hole, so that when the socket 1 is combined with the socket wrench 9, as shown in the second and third figures, the C-shaped retaining ring 8 on the socket wrench 9 and the socket The notch 2 on the sleeve 1 is temporarily engaged and positioned to prevent the sleeve 1 from detaching from the sleeve wrench 9 by itself. However, this design, in addition to having a slot 2 on the sleeve 1, can only be used with a special socket wrench 9 (a socket wrench 9 with a C-shaped retaining ring 8), which not only requires additional expenses The cost of purchasing a special socket wrench 9 also makes it easy to be restricted in use.
In addition, there is also a sleeve 3, as shown in Figures 4 and 5, which is provided with a radially annular locking groove 4 on its outer peripheral surface for a C-shaped retaining ring 5 to be locked. This kind of socket 3 can be matched with the existing socket wrench 6 without purchasing a special socket wrench. However, since this sleeve 6 must be snapped into the C-shaped retaining ring 5, the groove depth of the slot 4 is deeper, which causes the thickness D of the sleeve 6 originally, and the thickness d at the position of the slot 4 becomes thinner. As a result, the strength is reduced, and there are problems of easy damage and shortened service life.

In view of this, in order to improve the prior art, the conventional sleeve has to be matched with a special socket wrench to have a temporary combined positioning effect, and there are problems with the use of the socket and the cost of purchasing a special socket wrench, and Providing a C-shaped buckle on the sleeve will cause the overall strength to decrease, and there are problems of easy damage and shortened service life; therefore, the present invention provides a sleeve with elastic binding positioning, which mainly includes a sleeve body and An elastic positioning body; the sleeve body has a driving portion and a turning portion which is coaxially and integrally connected with the driving portion; a ring groove is formed on the outer periphery of the driving portion; the elastic positioning body is in a C-shaped sheet shape and has a top end A bottom end located at the opposite end position of the top end and a radial deformation part connected between the top end and the bottom end, the radial deformation part can be elastically deformed radially by an external force, and the top end of the elastic positioning body It is engaged with the bottom end in the ring groove of the sleeve body, and the radial deformation part protrudes out of the ring groove; thus, it can not only achieve temporary binding with the existing socket wrench. Orientation of efficacy, thus reducing more open annular groove of the desired depth, dimensions of the overall intensity, and other effects further enhance the service life.

In order to enable your reviewers to further understand and agree with the features and characteristics of the present invention, the following preferred embodiments are listed and illustrated with the drawings as follows:
Please refer to FIG. 6 to FIG. 9, which show a sleeve 100 with elastic coupling and positioning provided by a preferred embodiment of the present invention, which mainly includes a sleeve body 10 and an elastic positioning body 20, wherein:
Please refer to the sixth to ninth figures. The sleeve body 10 has a driving portion 11 and a turning portion 12 which is coaxially and integrally connected with the driving portion 11. The cross section of the outer portion of the driving portion 11 is hexagonal. The free end of the driving portion 11 has a driving hole 111 extending inward. In this embodiment, the driving hole 111 is a square hole. The driving portion 11 has a ring groove 112 on the outer peripheral surface. The free end has a turning hole 121 extending inward, the turning hole 121 is in communication with the driving hole 111, and the diameter of the turning hole 121 is larger than the driving hole 111. In this embodiment, the turning hole 121 is a hexagonal hole.
Please refer to the sixth to ninth figures. The elastic positioning body 20 is made of metal and has a C-shaped sheet shape, which can define a top end 21, a bottom end 22 located at the opposite end position of the top end, and a connection to A radial deformation part 23 between the top end 21 and the bottom end 22, the radial deformation part 23 can be elastically deformed in the radial direction by an external force; the top end 21 of the elastic positioning body 20 and the bottom end 22 are engaged with each other. In the ring groove 112 of the sleeve body 10, the radial deformation portion 23 protrudes out of the ring groove 112.
Therefore, the above is an introduction to the components and assembly methods of a sleeve 100 with elastic binding positioning provided by a preferred embodiment of the present invention, and then its use characteristics are described as follows:
When the driving part 11 of the sleeve 100 with elastic binding and positioning according to the present invention is sleeved with a sleeve wrench 90 (as shown in the eighth and ninth figures), the radial deformation that originally protrudes outside the ring groove 112 The part 23 is radially deformed inward by the inner wall 91 of the sleeve hole of the socket wrench 90, that is, the radially deformed part 23 is contracted and displaced toward the inner side 232 from the outer side 231, so that At this time, the radial deformation portion 23 accumulates an elastic pre-force that is pushed out in the direction of the outer surface 231 (that is, toward the inner wall of the sleeve hole 91), so that the sleeve formed by the radial deformation portion 23 and the socket wrench 90 can be set. The inner wall 91 of the hole produces a temporary combined positioning effect, so that the sleeve 100 and the sleeve wrench 90 of the present invention with the elastic combined positioning will not detach themselves.
In addition, since the radial deformation portion 23 of the elastic positioning body 20 in the present invention has the capability of radial deformation, the depth of the ring groove 112 provided on the sleeve body 10 only needs to be extremely shallow, as shown in the ninth figure The thickness d of the sleeve body 10 at the position of the ring groove 112 and the thickness D of other positions of the sleeve body 10 are almost the same, and the overall strength can be ensured to achieve the effect of improving the service life.
Furthermore, although the outer side surface 231 of the radial deformation portion 23 is a convex arc surface in the above embodiment, the inner side surface 232 of the radial deformation portion 23 is a concave arc surface. However, in fact, as shown in the tenth figure, the outer side surface 233 of the radial deformation portion 23 may be a convex convex cone surface, and the inner side surface 234 of the radial deformation portion 23 is a concave concave cone surface. Or, as shown in the eleventh figure, in addition to the top 21, the bottom 22, and the radial deformation portion 23, the elastic positioning body 20 further has a top end connected between the top 21 and the radial deformation 23. The straight section 24 and a straight section 25 at the bottom end connected between the bottom end 22 and the radial deformation portion 23 can achieve the same effect.
Secondly, in the present invention, when the radial deformation portion 23 of the elastic positioning body 20 undergoes radial displacement deformation, the distance between the top end 21 and the bottom end 22 will also change accordingly.
The above disclosure is only the preferred embodiments provided by the present invention, and is not intended to limit the scope of implementation of the present invention. Any equivalent changes made by those skilled in the art in accordance with the present invention should belong to the present invention. Coverage.
