[0020] It will be directed to the Fig. 1 and Fig. 2. Referenced. Fig. Figure 1 shows a schematic perspective view of the socket wrench insert 10 according to a first embodiment of the present invention; and Fig. Figure 2 shows a schematic sectional view of the socket wrench insert 10. Fig. 1 according to the first embodiment of the present invention. The socket wrench insert 10 comprises a plug-in connection structure 100, a stop structure 200, and an actuating structure 300. The plug-in connection structure 100 has a plug-in body 110, a plug-in hole S1, and at least one inclined, conical recess 120. One end of the plug-in body 110 has a plug-in hole circumference 130. The plug-in hole S1 extends through the plug-in body 110. The inclined, conical recess 120 is provided on the plug-in body 110. The stop structure 200 is arranged at the end opposite the plug-in body 110. The actuating structure 300 is arranged at one end of the stop structure 200.The inclined, conical recess 120 extends from the socket hole circumference 130 to the stop structure 200, so that a socket wrench insert drive element (not shown) can slide along the inclined, conical recess 120 and be inserted into the socket hole S1.
[0021] In this way, the arrangement of the inclined, conical recess 120 on the plug-in body 110 allows a socket wrench drive element to be inserted more quickly into the plug-in hole S1 of the socket wrench insert 10, which significantly improves the ease of use of the socket wrench insert 10.
[0022] The actuating structure 300 can comprise an actuating body 310 and an actuating hole S2, the actuating hole S2 passing through the actuating body 310. Both the plug-in connection structure 100 and the actuating structure 300 are essentially tubular in design. The stop structure 200 is a hollow ring body designed such that the plug-in connection hole S1 arranged on the plug-in connection structure 100 can be continuously connected to the actuating hole S2 arranged on the actuating structure 300 through a central space (not shown) of the stop structure 200. It should be emphasized that the inner diameter of the stop structure 200 is smaller than the smallest diameter (not shown) of the plug-in connection hole S1 and the smallest diameter (not shown) of the actuating hole S2. The socket wrench drive element can, for example,The actuator 300 may be a socket wrench and have a connector section whose shape is approximately matched to the shape of the connector hole S1, so that the connector section can be inserted into the connector hole S1. The actuator structure 300 may be matched to a locking piece (not shown) so that it can be locked or unlocked by the actuator structure 300.
[0023] As in Fig. As shown in Figure 1, the connector hole S1 can be a square hole and the connector body 110 can have four corners, with a connector recess 160 provided at each corner, extending from the connector hole circumference 130 to the stop structure 200. Specifically, the connector hole S1 is a square through hole, with the connector hole circumference 130 located at the end of the connector body 110 facing away from the actuating structure 300. Each connector recess 160 is arc-shaped and extends vertically from the connector hole circumference 130 to the stop structure 200.By arranging the plug connection recesses 160 at the four corners of the plug connection body 110, sufficient space can be created to allow the four corners of the plug connection section of a socket wrench insert drive element to be moved in and out, so that the plug connection section can be easily inserted into the plug connection hole S1.
[0024] The inclined, conical recess 120 can have a concave surface and taper from the circumference of the socket hole 130 towards the stop structure 200. In the present embodiment, there are four inclined, conical recesses 120, each located on the four inner walls of the socket body 110. All inclined, conical recesses 120 extend and taper from the circumference of the socket hole 130 towards the stop structure 200, gradually tapering inwards in the radial direction of the socket insert 10. The socket structure 100 can also have external teeth 170.The inclined, conical recesses 120 make it possible to omit a chamfer on the connector body 110 while maintaining the thickness between the connector hole circumference 130 and the outer tooth circumference 180 of the external toothing 170, thereby improving structural strength. In other embodiments, the number of inclined, conical recesses need not be four; however, the present invention is not subject to any limitations in this respect.
[0025] It will be directed to the Fig. 3 and Fig. 4 and simultaneously on the Fig. 1 and Fig. 2. Referenced. Fig. Figure 3 shows a top view of the socket wrench insert 10. Fig. 1 according to the first embodiment of the present invention; and Fig. Figure 4 shows a sectional view of the socket wrench insert 10. Fig. 2 according to a second embodiment of the present invention along section line 4-4. The external teeth 170 of the connector structure 100 are located on the outer wall of the connector body 110 and can have several external tooth projections 171 and several external tooth recesses 172, with each external tooth recess 172 being located between two adjacent external tooth projections 171. The connector structure 100 can have an outer connector circle 150 that is connected to the tips of all external tooth projections 171. The diameter of the outer connector circle 150 is smaller than the outer diameter of the actuating structure 300. The outer connector circle 150 is an imaginary circle in which the center of the connector hole S1 represents the center of the circle.
[0026] Specifically, the external toothing 170 can be formed integrally as a ring on the outer wall of the connector body 110. The external tooth projections 171 of the external toothing 170 protrude outwards along the radial direction of the socket insert 10, while the external tooth recesses 172 of the external toothing 170 are recessed inwards along the radial direction of the socket insert 10, with both the multiple external tooth projections 171 and the multiple external tooth recesses 172 extending perpendicularly from the end of the connector body 110 facing away from the actuating body 310 in the direction of the actuating body 310.Each external tooth recess 172 is located between two adjacent external tooth projections 171, and each external tooth projection 171 is located between two adjacent external tooth recesses 172, such that the number of multiple external tooth projections 171 and the number of multiple external tooth recesses 172 are equal. In the present embodiment, the number of multiple external tooth projections 171 and the number of multiple external tooth recesses 172 are each twelve, wherein the connection of the tips of these twelve external tooth projections 171 defines a plug-in connection outer circle 150, the diameter of which is smaller than the outer diameter of the actuating structure 300.In other embodiments, the number of external tooth projections and external tooth recesses can be greater or less than twelve, and the diameter of the plug connection's outer circle can also be equal to or greater than the outer diameter of the actuating structure; however, the present invention is not subject to any limitations in this respect. It is particularly noteworthy that the ring-shaped external toothing 170 provided on the plug connection structure 100 allows the user to grip the external toothing 170 directly with their hand and rotate the socket 10 by utilizing the friction between the external toothing 170 and their hand. Furthermore, a socket drive element can be attached to the external toothing 170 to increase the torque and facilitate rotation of the socket 10.
[0027] As in Fig. As shown in Figure 3, the plug-in connection structure 100 of the socket wrench insert 10 can have at least one diagonal thickness D1, which is given between at least one of the four corners of the plug-in body 110 and the outer edge of the plug-in body 110, passes through the center point of the plug-in hole circumference 130, and represents the minimum thickness of the plug-in body 110. In detail, the center point of the plug-in hole circumference 130 can be extended towards each corner of the plug-in hole circumference 130 to define an imaginary extension line 140, wherein the imaginary extension line 140 corresponds to a point on the plug-in hole circumference 130 and a point on the outer tooth circumference 180 of the outer toothing 170.The diagonal thickness D1 is defined as the distance between the point on the plug connection hole circumference 130 and the point on the outer tooth circumference 180 of the outer toothing 170 and represents the minimum thickness of the entire plug connection body 110.
[0028] Specifically, the center point of the connector hole circumference 130 can extend towards the four corners where the four connector recesses 160 are arranged to form four imaginary extension lines 140, with the four imaginary extension lines 140 passing successively through the connector hole circumference 130 and the outer tooth circumference 180. The distance between the intersection of each imaginary extension line 140 with the connector hole circumference 130 and the outer tooth circumference 180 represents the diagonal thickness D1. In the present embodiment, the diagonal thickness D1 is less than 4 mm. In other embodiments, the diagonal thickness can be greater than or equal to 4 mm, but is not limited to this.
[0029] As in Fig.As shown in Figure 4, the actuating structure 300 has an actuating body 310 and internal teeth 330, wherein the internal teeth 330 are provided on the inner wall of the actuating body 310 and have several internal tooth projections 331 and several internal tooth recesses 332, each internal tooth recess 332 being located between two adjacent internal tooth projections 331. The actuating structure 300 may have an actuating inner circle 320, which is connected to the tips of all internal tooth projections 331. The diameter of the actuating inner circle 320 is larger than the inner diameter of the stop structure 200, wherein the actuating inner circle 320 is an imaginary circle where the center of the actuating hole S2 is the center of the circle.It is particularly noteworthy that the center point of the plug connection hole S1, the center point of the actuating hole S2 and the center point of the plug connection hole circumference 130 are collinear and lie on a central axis C1, where the central axis C1 is an imaginary axis and runs parallel to the longitudinal direction of the socket wrench insert 10.
[0030] Specifically, the internal toothing 330 can be formed integrally as a ring on the inner wall of the actuating body 310. The internal tooth projections 331 of the internal toothing 330 protrude inwards along the radial direction of the socket wrench insert 10, while the internal tooth recesses 332 of the internal toothing 330 are recessed outwards along the radial direction of the socket wrench insert 10, with both the multiple internal tooth projections 331 and the multiple internal tooth recesses 332 extending perpendicularly from the end of the actuating body 310 facing away from the connector body 110 in the direction of the connector body 110.Each internal tooth recess 332 is located between two adjacent internal tooth projections 331, and each internal tooth projection 331 is located between two adjacent internal tooth recesses 332, such that the number of internal tooth projections 331 and the number of internal tooth recesses 332 are equal. In the present embodiment, the number of internal tooth projections 331 and the number of internal tooth recesses 332 are each twelve, wherein the connection of the tips of these twelve internal tooth projections 331 defines an actuating inner circle 320, the diameter of which is larger than the inner diameter of the stop structure 200. When a locking element is screwed in or loosened, it can be brought into engagement with the internal toothing 330 and limited by the stop structure 200, and thus held in the actuating hole S2.In other embodiments, the number of internal tooth projections and internal tooth recesses may not be twelve, however, the present invention is not subject to any limitations in this respect.
[0031] The plug-in connection structure 100, the stop structure 200, and the actuating structure 300 can be formed in one piece. In the present embodiment, all structures of the socket wrench insert 10 (i.e., all components) are formed in one piece, wherein the plug-in connection hole S1, the inclined, conical recess 120, the plug-in connection recess 160, the actuating hole S2, the external toothing 170, and the internal toothing 330 can all be arranged accordingly on the forming tool of the socket wrench insert 10, whereby the socket wrench insert 10 can be completely manufactured in a single forging operation, which not only reduces production time but also significantly lowers manufacturing costs.
[0032] The foregoing description presents only preferred embodiments of the invention and is not intended to limit the scope of the claims. All equivalent changes and modifications that can be made by a person skilled in the art in this field according to the description and drawings of the invention fall within the scope of protection of the present invention.
