Description

Field of invention

[0001] The present invention relates to a socket wrench insert structure and in particular to a non-rolling socket wrench insert. State of the art

[0002] A socket wrench insert is a basic hand tool widely used in mechanical engineering, automotive maintenance, construction, electronics assembly, and DIY projects. Its primary purpose is the efficient, precise, and safe tightening or loosening of screws, nuts, and other fasteners. A socket wrench insert is essentially a cylinder with a specific hexagonal or dodecagonal internal profile, designed to completely enclose the head of a fastener and driven by a wrench handle, ratchet, or pneumatic tool.

[0003] In tasks such as vehicle maintenance or machine assembly, where frequent changes of different-sized sockets are necessary, technicians often place several spare sockets loosely on a workbench, work surface, or the flat surface of the equipment being serviced. Because the socket is cylindrical (i.e., has a circular cross-section), even slight tilts, vibrations, or minor impacts on the work surface cause it to roll away immediately. Thus, the rolling nature of the cylindrical socket contradicts its intended attribute as an efficient, easily accessible tool, clearly demonstrating the problem of instability and workflow disruptions in existing setups. Object of the invention

[0004] One object of the present invention is to provide a roll-resistant socket wrench insert in order to improve operational stability and the smoothness of the workflow.

[0005] To solve the above-mentioned problem, the present invention provides a roll-resistant socket wrench insert comprising: a socket wrench insert body having an outer circumferential surface; and a stop ring which is mounted on the outer circumferential surface of the socket wrench insert body and has an outer ring section projecting beyond the outer circumferential surface, wherein the outer ring section is non-circular in design.

[0006] The advantageous effects of the present invention consist in the fact that, due to the stop ring, which has a non-circular outer ring section projecting beyond the outer circumferential surface of the socket wrench insert body, a stop edge, corner or support point is provided between the non-circular outer ring section and the flat surface when the socket wrench insert body is placed on a flat surface, thereby preventing uncontrolled rolling of the socket wrench insert body on the flat surface, which effectively improves operational stability and the smoothness of the workflow.

[0007] Preferably, the outer ring section of the stop ring is polygonal. The polygonal structure more effectively prevents uncontrolled rolling of the socket wrench insert body on a flat surface.

[0008] Preferably, the outer ring section of the stop ring has at least one flat stop surface. The design of this flat stop surface allows the socket insert body to lie flush when placed on a flat surface, thus preventing uncontrolled rolling of the socket insert body.

[0009] Preferably, the socket insert body further comprises a drive recess and a working recess opposite the drive recess, wherein the stop ring is mounted on the outer circumferential surface of the socket insert body and corresponds to the drive recess or the working recess. Because the stop ring is mounted on the socket insert body and then corresponds to the drive recess or the working recess, the user can immediately determine the position of the drive recess or the working recess when gripping the socket insert body based on the position of the stop ring, without having to pay attention to the appearance of the socket insert body, thus increasing work efficiency.

[0010] Preferably, the socket wrench insert body further has a positioning groove recessed into the outer circumferential surface, wherein the stop ring further has an inner ring section opposite the outer ring section and partially positioned in the positioning groove, so that the stop ring is stably fixed to the socket wrench insert body.

[0011] According to the embodiment described above, the socket wrench insert body preferably further comprises a drive recess and a working recess opposite the drive recess, wherein the number of positioning grooves is two, each corresponding to the drive recess and the working recess, wherein the number of stop rings is one and the inner ring section of the stop ring can be selectively positioned in one of the positioning grooves.Because the stop ring is mounted on the socket insert body and then corresponds to the drive recess or the working recess, when combining it with a drive tool or a locking / unlocking element, the user can immediately determine the position of the drive recess or the working recess by the position of the stop ring when gripping the socket insert body, without having to pay attention to the appearance of the socket insert body, thus increasing work efficiency.

Detailed description of the exemplary implementations

[0012] It will be directed to the Fig. Reference is made to sections 1 to 3B. The anti-roll socket wrench insert according to a first embodiment of the present invention primarily consists of a socket wrench insert body 10 and a stop ring 20.

[0013] The socket wrench insert body 10 is cylindrical and has an outer circumferential surface 11, a drive recess 12 which can be combined with a drive tool (not shown), a working recess 13 opposite the drive recess which can be combined with a locking / unlocking element (not shown), and two positioning grooves 14 recessed into the outer circumferential surface 11 which correspond to the drive recess 12 and the working recess 13.

[0014] The stop ring 20 is an elastic ring body that is mounted on the outer circumferential surface 11 of the socket wrench insert body 10 and has an outer ring section 21 projecting beyond the outer circumferential surface and an inner ring section 22 opposite the outer ring section 21 and partially positioned in a positioning groove 14, wherein the inner ring section 22 can be selectively positioned in one of the positioning grooves 14. In the present embodiment, the inner ring section 22 of the stop ring 20 is positioned in the positioning groove 14 corresponding to the drive recess 12, but is not limited to this position. Alternatively, it can be positioned in the positioning groove corresponding to the working recess 13. Furthermore, the outer ring section 21 of the stop ring 20 is non-circular.In the present embodiment, the outer ring section 21 of the stop ring 20 is hexagonal and has six flat stop surfaces 211, but is not limited to this. Alternatively, it can be pentagonal, heptagonal, or octagonal.

[0015] The structure and configuration of the main components of the first embodiment are described above. The functionality and advantageous effects of the present invention are explained below.

[0016] It will be directed to the Fig. 4A and Fig. Reference is made to Figure 4B. Due to the hexagonal outer ring section 21 of the stop ring 20, which projects beyond the outer circumferential surface 11 of the socket wrench insert body 10, the outer ring section 21 can rest flush on one of the flat stop surfaces 211 when the socket wrench insert body 10 is placed on a flat surface 30, with at least one flat stop surface 211 forming a stop edge, corner, or support point, thereby preventing uncontrolled rolling of the socket wrench insert body 10 on the flat surface 30. Thus, the design of the anti-roll socket wrench insert according to the invention meets the requirements of an easily accessible, highly efficient tool and effectively improves operational stability and the smoothness of the workflow.

[0017] It will be referred to again as... Fig. 2 and Fig. Reference is made to Figure 3A. It should be noted that only one stop ring 20 is present and its inner ring section 22 can be selectively positioned in one of the positioning grooves 14. In the present embodiment, the stop ring 20 is placed onto the socket insert body 10 and then corresponds to the drive recess 12 (or the working recess 13). When combined with a drive tool or a locking / unlocking element, the user can immediately determine the position of the drive recess 12 or the working recess 13 by means of the position of the stop ring 20 when gripping the socket insert body 10, without having to pay attention to the appearance of the socket insert body 10, which increases work efficiency.

[0018] It will be on Fig. 5. A roll-resistant socket wrench insert according to a second embodiment of the present invention also consists of a socket wrench insert body 10 and a stop ring 20. The difference between the second embodiment and the first embodiment is described below:

[0019] The outer circumferential surface 11 of the socket insert body 10 is not provided with a positioning groove. The stop ring 20 is placed directly onto the outer circumferential surface 11 of the socket insert body 10, so that the inner ring section 22 of the stop ring 20 is positioned directly on the outer circumferential surface 11 of the socket insert body 10. This simplifies the manufacture of the socket insert body 10 and reduces manufacturing costs.

[0020] It will be directed to the Fig. 6 and Fig.7. A roll-resistant socket wrench insert according to a third embodiment of the present invention also consists of a socket wrench insert body 10 and a stop ring 20. The difference between the third embodiment and the first embodiment is described below:

[0021] The outer ring section 21 of the stop ring 20 is non-circular and has only a flat stop surface 211. Due to the design of the flat stop surface 211, the socket wrench insert body 10 can lie flush when placed on a flat surface 30, thus preventing uncontrolled rolling of the socket wrench insert body 10 and also improving operational stability and the smoothness of the work process.

[0022] The anti-roll socket insert according to the invention comprises the following: a socket insert body having an outer circumferential surface; and a stop ring mounted on the outer circumferential surface of the socket insert body, the stop ring having an outer ring section projecting beyond the outer circumferential surface, wherein the outer ring section is non-circular. The stop ring, which has a non-circular outer ring section projecting beyond the outer circumferential surface of the socket insert body, provides a stop edge, corner, or support point between the non-circular outer ring section and the flat surface when the socket insert body is placed on a flat surface, thus preventing uncontrolled rolling of the socket insert body on the flat surface and effectively improving operational stability and the smoothness of the workflow.
