Description

[Technical field]

[0001] The invention relates to a socket, in particular a socket wrench insert. [State of the art]

[0002] A conventional socket usually has a smooth surface (please refer to Fig. 1 from TWM558688U). When operating the socket, the surface must be gripped with the palm of the hand, but sweat or oil stains on the palm make it difficult to grip the smooth surface with the palm. In addition, when placing the socket on a work surface (e.g., a machine table), there is a risk that the socket will roll away due to the smooth surface. This can easily cause the socket to fall off, resulting in inconvenience during operation and a greater time consumption for the same work.

[0003] In view of this, the inventor of the present invention has engaged in the research and development of socket wrench inserts and ultimately produced a socket wrench insert according to the invention. (Content of the invention)

[0004] The invention is based on the object of creating a socket wrench insert which avoids the disadvantages associated with the prior art.

[0005] According to one embodiment, the invention provides a socket wrench insert comprising a main body having an axis, the main body having a side body on which a plurality of recesses are arranged in a spaced-apart annular manner, the recesses being formed along the axis on the side body between the two ends of the main body such that they taper along the axis and thereby each have an included angle.

[0006] According to the invention, the recesses simultaneously provide an anti-slip and anti-roll function, so that work using the socket wrench insert can be carried out undisturbed and with reduced time expenditure.

[0007] The above description merely serves to explain the objects of the invention, the technical means for achieving the objects, and the resulting advantages.

[0008] In order for the examiner to better understand the present invention, the present invention will be explained in more detail below with reference to the detailed description of the preferred embodiments and the accompanying drawings:

[0009] As in Fig. 1 to Fig. 130, the invention relates to a socket wrench insert. According to the first embodiment (see Fig. 1 to Fig. 9) The socket includes a main body 10 formed by forging, but the forming of the main body 10 is limited to the forging process. The appearance of the main body 10 is approximately the same as a cylinder.

[0010] As in Fig. 1, the main body 10 has an axis 10A along which a small-diameter portion 11 and a large-diameter portion 12 connected to the small-diameter portion 11 are axially arranged on the main body 10, wherein the largest outer diameter of the small-diameter portion 11 is smaller than the largest outer diameter of the large-diameter portion 12. Furthermore, a connecting portion 13 is arranged between the small-diameter portion 11 and the large-diameter portion 12 to connect the small-diameter portion 11 and the large-diameter portion 12 to each other. The connecting portion 13 is provided with a connecting angle, which may be an arc angle, an oblique angle, or a right angle, or a combination thereof, wherein the oblique angle includes acute angles (greater than 0° and less than 90°) and obtuse angles (greater than 90° and less than 180°).

[0011] As in Fig. 1, a loaded part 111 is arranged on the small diameter section 11, which runs from one end side of the main body 10 along the axis 10A, wherein the small diameter section 11 is recessed towards the large diameter section 12 so that a loaded opening 112 is formed. A force introduction part 121 is arranged on the large diameter section 12, which runs from the other end side of the main body 10 along the axis 10A, wherein the large diameter section 13 is recessed towards the small diameter section 11 so that a force introduction opening 122 is formed.

[0012] The loaded part 111 and the force introduction part 121 may be recesses that are not connected to each other or holes that are connected to each other, but are not limited to recesses or holes. For the recesses referred to here, reference is made to the Fig. 5 from the TWM558688U and for the holes meant here, refer to the holes shown in Fig. 9 from the TWM558688U or the Fig. 1 holes shown in TW249372U.

[0013] As in Fig. 1 and Fig. 4, the loaded part 111 is connected to a force introduction element E via the loaded opening 112, where the force introduction element E is, for example, a wrench, but is not limited to wrenches. The force introduction part 121 is connected to a loaded element R via the force introduction opening 122, where the loaded element R is, for example, a screw, but is not limited to screws. The user applies a force to the force introduction element E such that the loaded part 111 of the small-diameter section 11 is rotated under the application of force. As a result, the force introduction part 121 of the large-diameter section 12 applies a force to the loaded element R, so that the loaded element R is rotated under the application of force.

[0014] As in Fig. 1, a side body 12A is provided on the outer wall of the large-diameter portion 12 of the main body 10, which side body 12A encloses the axis 10A. A plurality of recesses 20 are arranged in a spaced-apart annular manner on the side body 12A of the large-diameter portion 12, the recesses 20 being formed along the axis 10A at one end of the side body 12A similar to rifle bullets.

[0015] As in Fig. 1, a first end 12A1 and a second end 12A2 are further defined on the side body 12A, wherein the recesses 20 extend from the second end 12A2 (i.e., the recesses 20 contact the second end 12A2) and terminate before the first end 12A1 (i.e., the recesses 20 do not contact the first end 12A1). A parting line 12A3 is further defined between the first end 12A1 and the second end 12A2, which may be a centerline, wherein the distance from the centerline to the first end 12A1 and the distance from the centerline to the second end 12A2 are equal. The recesses 20 end at the parting line 12A3 (i.e., the recesses 20 touch the parting line 12A3) or before the parting line 12A3 (i.e., the recesses 20 do not touch the parting line 12A3).

[0016] The recesses 20 taper along the axis 10A in such a way that they each have an included angle 20A (see Fig. 1). The recesses 20 taper along the axis 10A from the front end to the rear end in such a way that at the rear end of the respective recess 20 an included angle 20A is formed, which becomes increasingly narrower (see Fig. 1, along the axis from the front end to the rear end) and increasingly flatter (see Fig. 2, along the axis from the front end to the rear end). In sectional view in the X-direction, the included angle 20A can be a round angle (see Fig. 2A, Fig. 2B), an arc angle (see Fig. 2C) or a bevel angle or a combination thereof, whereby the bevel angle can be designed as an acute or obtuse angle as required. The recesses 20 facilitate rolling (see Fig. 5) and slipping (see Fig. 6) of the main body 10. Varying the included angle 20A of the recess 20 results in different effects. For example, an acute angle provides a stronger anti-slip effect for a specific direction; a right angle provides a clear holding point against rolling; an obtuse angle provides a larger contact area; a round angle reduces stress concentration; and an arcuate angle provides a gradual anti-slip effect. A combination of the aforementioned angle types is also conceivable according to the invention. For example, the recesses 20 can be designed with different angles at different locations to ensure an anti-slip and anti-roll effect under different working conditions.

[0017] As in Fig. 1 and Fig. 2, a straight section 21 and a tapered section 22 are further arranged on the respective recess 20 along the axis 10A from the front end to the rear end, wherein the tapered section 22 adjoins the straight section 21 and has the included angle 20A, wherein the straight section 21 has an arc shape in the Y direction in sectional view (see Fig. 3A), an inverted U shape (see Fig. 3B) or a shape of an inverted, widened V (see Fig. 3C) or a combination thereof. The Y-direction and the X-direction intersect, specifically at right angles or perpendicular to each other.

[0018] Alternatively, the respective recess 20 of the large-diameter portion 12 may be formed at the other end of the side body 12A along the axis 10A. The respective recess 20 may also start from the first end 12A1 (not shown in the drawing, meaning that the recesses 20 touch the first end 12A1) and end before the second end 12A2 (not shown in the drawing, meaning that the recesses 20 do not touch the second end 12A2). Furthermore, the recesses 20 may end at the parting line 12A3 (not shown in the drawing, meaning that the recesses 20 touch the parting line 12A3) or before the parting line 12A3 (not shown in the drawing, meaning that the recesses 20 do not touch the parting line 12A3).

[0019] It is also conceivable to form the recesses 20 of the large-diameter section 12 simultaneously at both ends of the side body 12A along the axis 10A, with the recesses 20 also starting from the above-mentioned locations and ending at the above-mentioned locations. It should be noted that the recesses 20 at both ends of the side body 12A do not touch each other.

[0020] On the outer wall of the side body, another loaded part 113 (see Fig. 1) be arranged in the small diameter section 111 such that the loaded part 113 encloses the axis 10A. The loaded part 113 is assembled with another force introduction element having a force introduction opening (see Fig. 5 from the TWM243300U), whereby the force introduction element here can be a wrench. It is possible to arrange the loaded parts 111, 113 both on the small diameter section 11 (see Fig. 1), or to arrange only one of the two loaded parts 111, 113 on the small diameter section 11 (Not shown in the drawing. This means that either the loaded part 111 or the loaded part 113 is arranged on the small diameter section 11.)

[0021] In Fig. 7 to Fig. 9, the main body 10 of the first embodiment is shown in different operating states and in different developments. For the first embodiment, reference is also made to Fig. 40 to Fig. 46.

[0022] Further reference is made to Fig. 10 to Fig. 17. The second embodiment is explained below. As shown in Fig. As shown in Figure 10, the second embodiment differs from the first embodiment by the changes to the small diameter section 11', the large diameter section 12', and the connecting section 13', wherein the recesses 20 are also formed in a bullet-like shape, as in the first embodiment. In a perspective view (see Fig. 10) and in front view (see Fig. 11. The main body 10' is the same in rear view and front view, so the explanation of the main body 10' in rear view is omitted here.) The main body 10' is shown with the broken line in Fig. 11 indicates that the small diameter section 11' and the large diameter section 12' are longitudinally consistent in shape and structure or exhibit a certain regular variation. The main body 10' is shown in left view (see Fig. 12. The main body 10' is the same in right and left view, so the explanation of the main body 10' in right view is omitted here.), in plan view (see Fig. 13) and from below (see Fig. 14). Furthermore, the main body 10' is adapted in various further developments to the recesses 20 in a bullet-like shape (see Fig. 15, Fig. 16 and Fig. 17).

[0023] Further reference is made to Fig. 10 to Fig. 17. The third embodiment is explained below. As in Fig. 18, the third embodiment differs from the second embodiment in that the recesses 20' are formed in a capsule-like shape. The main body 10' remains unchanged. In perspective view (see Fig. 18) and in front view (see Fig. 19. The main body 10' is the same in rear view and front view, so the explanation of the main body 10' in rear view is omitted here.) The main body 10' is shown with the broken line in Fig. 19 indicates that the small diameter section 11' and the large diameter section 12' are longitudinally consistent in shape and structure or exhibit a certain regular variation. The main body 10' is shown in left view (see Fig. 20. The main body 10' is the same in right and left view, so the explanation of the main body 10' in right view is omitted here.), in plan view (see Fig. 21) and from below (see Fig. 22). Furthermore, the main body 10' is adapted in various further developments to the recesses 20' in a capsule-like shape (see Fig. 23, Fig. 24 and Fig. 25). For the third embodiment, further reference is made to Fig. 26 to Fig. 32.

[0024] Further reference is made to Fig. 47 to Fig. 53. The fourth embodiment is explained below. As in Fig. As shown in Figure 47, the fourth embodiment differs from the first, second, and third embodiments in that the outer circumference of the main body 10'' extends uniformly along the axis, so that the outer diameter of the main body 10'' remains the same, and the main body 10'' is not divided into a small-diameter section and a large-diameter section. The constant-diameter design of the main body 10'' provides better strength distribution. The recesses 20'' of the main body 10'' taper toward the two ends of the axis 10A'' to form two included angles 20A'' and one straight section 21'', and the number of included angles 20A'' of the tapered section 22'' is correspondingly increased to two.This results in the recesses 20" arranged between the two axial ends of the main body 10" tapering in two directions, providing an enhanced anti-slip effect. The unidirectional taper in the recesses 20, 20' and the bidirectional taper in the recesses 20" can be used individually or in combination.

[0025] Considering the distribution of structural strength between the two ends of the main body 10, 10', 10'', the recesses 20, 20' in the first, second, and third embodiments are not arranged on the side body 12A at both ends of the main body 10, 10', and the recesses 20'' in the fourth embodiment are not arranged on the side body 12A at both ends of the main body 10, 10'. Therefore, the recesses 20, 20', 20'' are arranged on the side body 12A between both ends of the main body 10, 10', 10'', but not on the side body 12A at the two ends. This ensures structural integrity and a certain degree of strength at the ends of the main body 10, 10', 10'' despite the action of a torsional force on the main body 10, 10', 10''.

[0026] The invention further provides two anti-slip and anti-roll structures, namely an annular groove 30 (see Fig. 33 to Fig. 39, Fig. 54 to Fig. 60, Fig. 68 to Fig. 74, Fig. 89 to Fig. 95, Fig. 103 to Fig. 109 and Fig. 130) and a 40 coin (see Fig. 61 to Fig. 67, Fig. 68 to Fig. 74, Fig. 75 to Fig. 81, Fig. 82 to Fig. 88, Fig. 89 to Fig. 95, Fig. 96 to Fig. 109, Fig. 110 to Fig. 116 and Fig. 117 to Fig. 130). The annular groove 30 and the embossing 40 can both be arranged between any two of the recesses 20, 20', 20'' and individually (see Fig. 33 to Fig. 39, Fig. 54 to Fig. 60, Fig. 61 to Fig. 67, Fig. 75 to Fig. 81, Fig. 82 to Fig. 88, Fig. 96 to Fig. 102, Fig. 110 to Fig. 116 and Fig. 117 to Fig. 123) or in combination (see Fig. 68 to Fig. 74, Fig. 89 to Fig. 95, Fig. 103 Fig. 109 and Fig. 124 to Fig. 130) to achieve optimal anti-slip and anti-roll effects. The designs of these two structures are explained in detail below.

[0027] According to the invention, at least one annular groove 30 is arranged between any two of the recesses 20, 20', 20'' on the side body 12A, which annular groove can be adjacent to the recesses 20, 20', 20'', connected to them, overlap them, or arranged with respect to them in a constellation with the equivalent effect. The annular groove 30 encloses the side body 12A in the circumferential direction of the main body 10 and thereby forms an annular structure running perpendicular to the axis 10A. The annular groove 30 crosses the recesses 20, 20', 20'' on the side body 12A such that a crossed structure is formed. When the annular groove 30 and the recesses 20, 20', 20'' intersect, the annular groove 30 can, depending on the requirements of various embodiments, either run continuously through the recesses 20, 20', 20'' or be interrupted within the recesses 20, 20', 20''. The number of annular grooves 30 can be at least one.In a plurality of annular grooves 30, the annular grooves 30 are distributed at equal or unequal distances on the side body 12A, wherein the width and depth of the annular groove 30 may be identical or not identical to those of the recesses 20, 20', 20'' and the cross section of the annular groove 30 may be rectangular, arcuate, V-shaped, U-shaped or in another geometric shape.

[0028] According to the invention, at least one embossing 40 is arranged between any two of the recesses 20, 20', 20'' on the side body 12A, which embossing can be adjacent to the recesses 20, 20', 20'', connected to them, overlapped or arranged in a constellation with the equivalent effect. The embossing 40 is formed on the surface of the side body 12A and thus forms an area with a geometric pattern of depressed and raised structures in order to significantly increase the friction of the user's hand contact. The embossing 40 can be made of crossed, annularly arranged stripes (see Fig. 61 to Fig. 67, Fig. 68 to Fig. 74, Fig. 75 to Fig. 81, Fig. 82 to Fig. 88 and Fig. 89 to Fig. 95), straight, ring-shaped stripes (see Fig. 96 to Fig. 102, Fig. 103 to Fig. 109, Fig. 110 to Fig. 116, Fig. 117 to Fig. 123 and Fig. 124 to Fig. 130) or a geometric pattern composed of a plurality of recessed and raised structures arranged in an array. The number of embossments 40 can be at least one. With a plurality of embossments 40, the embossments 40 are distributed evenly or unevenly on the side body 12A, wherein the depth of the embossment 40 can be identical or non-identical to that of the recesses 20, 20', 20'', and the height, spacing, and density of the embossment 40 can vary depending on the needs of different embodiments.

[0029] According to the invention, the annular groove 30 and the embossing 40 can both be located between the recesses 20, 20', 20'' and can be arranged individually or in combination on the side body 12A, depending on the application requirements and taking manufacturing into account. When the annular groove 30 and the embossing 40 are used individually, they can each provide an anti-slip and anti-roll effect. When the annular groove 30 and the embossing 40 are used in combination, they can together ensure an even more complete anti-slip and anti-roll effect. When used in combination, the annular groove 30 and the embossing 40 can be arranged adjacent to one another. For example, the annular groove 30 can be arranged between two adjacent embossments 40, or the embossment 40 can be arranged between two adjacent annular grooves 30. Alternatively, the annular groove 30 and the embossing 40 can be arranged in different areas of the side body 12A.The combination of ring groove 30 and embossing 40 is well suited for work requiring high precision, high torsion or work in difficult environments and can significantly increase the user-friendliness and safety of the tool.

[0030] All documents cited in this description are individually and expressly incorporated by reference into this description. If the definition or use of a term in a reference is inconsistent with or inconsistent with this description, the definition of the term in this description applies, and the definition of the term in the reference does not apply.

[0031] In summary, the present invention provides a “socket wrench insert” which, by means of the straight portion 21 and the tapered portion 22 of the recess 20, prevents the main body 10 (see Fig. 5) rolls when placed in a workplace. If the palm of a hand stained with stains (sweat or oil stains) touches the main body 10 (see Fig. 6), no slipping occurs, thus avoiding inconvenience during operation and shortening working time.

[0032] The socket according to the invention is characterized by the provision of recesses 20, 20', 20'' that taper along the axis 10A and thus each have an included angle 20A. The recesses 20, 20', 20'' simultaneously provide an anti-slip and anti-roll function. Thus, the socket offers the following technical advantages without compromising its structural strength:

[0033] Highly efficient transmission: The tapered design concentrates the force exerted on the axle, which contributes to reducing energy consumption, increasing transmission performance, and ensuring stable operation under torsional load.

[0034] Self-adjusting and anti-slip function: As the torsional force increases, the fingers are guided to narrower or flatter areas, so that the anti-slip effect gradually increases with the increase in the applied force, which contributes to increased grip security and effective slip resistance.

[0035] Roll-free operation and control: The tapered shape provides a stable support point, significantly reducing the risk of the socket rolling on uneven surfaces or when lying down, thus increasing operating safety.

[0036] Optimization of material consumption: Under the premise of maintaining structural strength, the socket insert is designed to become increasingly narrower and flatter, reducing material consumption, which contributes to both effective weight reduction and a reduction in manufacturing costs.

[0037] The invention thus relates to a socket wrench insert comprising a main body having an axis, wherein a small-diameter section and a large-diameter section connected to the small-diameter section are arranged along the axis on the main body, wherein the large-diameter section has a side body on which a plurality of recesses are arranged at a distance in a ring shape, wherein the recesses are formed along the axis at one or two ends of the side body such that they taper along the axis and thus each have an included angle. This creates a socket wrench insert that is slip- and roll-resistant, so that work using the socket wrench insert can be carried out uninterrupted and in a reduced time expenditure.

[0038] Finally, the embodiments disclosed above do not serve to limit the present invention. Modifications and developments of various kinds that can be made by those skilled in the art without departing from the spirit and scope of the invention are within the scope of the invention. Thus, the following claims are considered to be the scope of the present invention.
