[0025] This utility model proposes a screw 100.

[0026] Please see Figures 1 to 2 In one embodiment of the present invention, the screw 100 includes a nut 1 and a screw 2 connected to each other. The nut 1 has a first drive groove 11, and the screw 2 has a second drive groove 21 at one end away from the nut 1. The second drive groove 21 is configured to cooperate with a drive member to apply torque to the screw 100.

[0027] In this embodiment, the screw 100 can be applied to automated assembly lines and space-constrained areas, which is a specific application. It should be noted that the screw 2 and nut 1 are integrally formed, and both the nut end face and the screw end face of the screw 100 are planar. These two end faces are the opposite end faces of the entire screw 100. The driving component is an adapter tool for the first driving groove 11 and the second driving groove 21, which may include, but is not limited to, screwdrivers, wrenches, and hex wrenches. To enhance operational flexibility, the second driving groove 21 is formed at the end of the screw 2 furthest from the nut 1 through machining methods such as turning, injection molding, or milling; the machining method is not limited here. It is understood that the structural dimensions of the second drive groove 21 and the first drive groove 11 are not limited; that is, the dimensions of the first drive groove 11 and the second drive groove 21 can be kept consistent, so that only one tool is needed to unlock the first drive groove 11 and the second drive groove 21. Alternatively, the dimensions of the first drive groove 11 and the second drive groove 21 can be kept inconsistent to adapt to different mechanical requirements and optimize the overall structural strength. The shapes of the first drive groove 11 and the second drive groove 21 include, but are not limited to, straight lines, hexagonal shapes, and cross shapes.

[0028] The technical solution of this utility model, by providing a second drive groove 21 on the screw 2, allows the screw 100 to be operated not only from the nut 1 but also from the screw 2, greatly improving the flexibility and convenience of operation. Due to the addition of the second drive groove 21, even if the first drive groove 11 of the nut 1 wears or is damaged during use, the screw 100 can still be operated through the second drive groove 21 of the screw 2, ensuring the normal use of the screw 100 and improving its reliability and service life. Furthermore, when the screw 100 is applied to other components (such as the housing of the electronic product 200), the nut 1 can be hidden inside the other component (the housing of the electronic product 200), while the screw 2 faces outward. Compared to the prior art where the nut 1 is located outside the other component (the housing of the electronic product 200), since the nut 1 of this application is confined inside the other component (the housing of the electronic product 200), it can satisfy the user's ability to retain the screw 100 during disassembly, thereby effectively preventing the screw 100 from being lost due to accidental drop during disassembly, and further improving the stability of the screw 100 in practical applications.

[0029] In one embodiment of the present invention, the groove opening of the second drive groove 21 is arranged in a cross shape;

[0030] And / or, the slot of the second drive slot 21 is hexagonal in shape.

[0031] In this embodiment, combined with Figure 1In order to provide better torque transmission performance, the groove shape of the second drive groove 21 is set in a cross shape, so that the second drive groove 21 can be matched with common tools such as Phillips screwdrivers, reducing the cost of use.

[0032] To provide high torque transmission capability, the opening of the second drive groove 21 is set in a hexagonal shape, which makes the contact area between the tool and the groove wall of the second drive groove 21 larger. When transmitting torque, the stress distribution is more uniform, reducing the wear of the groove wall and improving the durability and service life of the screw 100.

[0033] In one embodiment of this utility model, the first drive groove 11 and the second drive groove 21 have the same structure.

[0034] In this embodiment, combined with Figure 2 In order to reduce production costs, the first drive groove 11 and the second drive groove 21 are designed to be the same size, so that the first drive groove 11 and the second drive groove 21 can be operated without changing tools during disassembly.

[0035] This utility model also proposes an electronic product 200, which includes a housing 210 and the aforementioned screw 100. The specific structure of the screw 100 is as described in the above embodiments. Since this electronic product 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The housing 210 includes an upper cover 211 and a bottom cover 212, with a portion of the upper cover 211 extending into the bottom cover 212; the screw 100 includes a nut 1 and a screw 2, with the nut 1 connected to the portion of the upper cover 211 extending into the bottom cover 212, and the screw 2 passing through and screwed into the bottom cover 212.

[0036] In this embodiment, it should be noted that the electronic product 200 includes, but is not limited to, speakers, display devices, etc., and is not limited here. Combined with Figure 3 and Figure 4 To enhance the connection strength of the housing 210, a portion of the upper cover 211 extends into the lower housing 212. It is understood that a flange or protrusion may be formed on the side of the upper cover 211 facing the lower housing 212, and the lower housing 212 correspondingly provides a support structure adapted to the flange or protrusion, thus allowing the upper cover 211 to mate with the lower housing 212. Furthermore, to make the connection between the upper cover 211 and the lower housing 212 tighter, this is achieved, including but not limited to, fixing via screws, snap-fit ​​connections, etc. Preferably, the upper cover 211 and the lower housing 212 are connected and fixed using bolts. Figure 5To prevent the screw 100 from being lost during the disassembly of the upper cover 211 and the bottom shell 212, the nut 1 is connected to the upper cover 211 and fixed through the side wall of the bottom shell 212. Here, the first drive groove 11 of the nut 1 can be tightened using a tool (screwdriver, etc.), and the second drive groove 21 of the screw 2 can also be tightened using a tool (screwdriver, etc.). In one embodiment, a first through hole is provided on the side of the upper cover 211 that extends into the bottom shell 212, and a second through hole is correspondingly provided on the inner side wall of the bottom shell 212. The first and second through holes are arranged opposite each other, and the screw 100 passes sequentially through one side of the upper cover 211 and the inner side wall of the bottom shell 212. In another embodiment, a blind groove is provided on the side of the upper cover 211 that extends into the bottom shell 212. The screw 2 passes from the inner wall of the bottom shell 212 to the outer wall of the bottom shell 212, and the nut 1 is confined within the blind groove. Specific implementation methods are described in the following embodiments. Specifically, when the upper cover 211 and the bottom shell 212 need to be disassembled, that is, when the screw 100 is operated with a tool, the screw 2 of the screw 100 can move outward, and the nut 1 disengages from the upper cover 211, thereby enabling the upper cover 211 to be disassembled from the bottom shell 212. Simultaneously, since the nut 1 of the screw 100 is confined inside the bottom shell 212 in this application, the screw 100 will not fall out of the bottom shell during the disassembly of the upper cover 211 and the bottom shell 212, thus preventing the screw 100 from being lost and significantly reducing the time users spend searching for the screw 100 during disassembly, greatly improving user satisfaction and user experience.

[0037] In one embodiment of the present invention, a connecting plate 213 is provided on the side of the upper cover 211 that extends into the bottom shell 212. The connecting plate 213 has a first slot 213a, and the side wall of the bottom shell 212 has a threaded hole 212a. The nut 1 is limited to the first slot 213a, and the screw 2 passes through the threaded hole 212a.

[0038] In this embodiment, combined with Figure 5 As can be seen, for easier disassembly, a connecting plate 213 is provided on the side of the upper cover 211 that extends into the bottom shell 212. The connecting plate 213 has a first slot 213a, the shape and size of which are adapted to the shape and size of the nut 1. The nut 1 of the screw 100 is confined within the first slot 213a, which is a blind slot. The screw 2 passes through the threaded hole 212a and extends out of the side wall of the bottom shell 212. The second drive groove 21 of the screw 100 can be tightened using a tool. The above-mentioned arrangement, by confining the nut 1 within the first slot 213a of the connecting plate 213, ensures that the nut 1 will not rotate during tightening, thus ensuring connection stability. At the same time, the limiting design increases the contact area between the nut 1 and the connecting plate 213, improving connection stability.

[0039] In one embodiment of the present invention, the electronic product 200 further includes a decorative cover 220, which is disposed on the outer side wall of the bottom shell 212 and covers the threaded hole 212a.

[0040] In this embodiment, combined with Figure 3 and Figure 5 To enhance the overall aesthetics of the electronic product 200, a decorative cover 220 is also included. The decorative cover 220 covers the threaded hole 212a, making the electronic product 200 more visually appealing. It should be noted that the decorative cover 220 can be part of the bottom shell 212. Specifically, a portion of the sidewall of the bottom shell 212 with the threaded hole 212a is cut to form a second slot 212b. This cut portion is the decorative cover 220, which is fitted into the second slot 212b. It should be noted that the screw 100 passes through a portion of the sidewall of the bottom shell 212. The decorative cover 220 can also be molded separately. The material of the decorative cover 220 includes, but is not limited to, metal (stainless steel, aluminum alloy, etc.) or plastic (polycarbonate). Specifically, the connection between the decorative cover 220 and the outer wall of the bottom shell 212 includes, but is not limited to, bonding, pressing, and magnetic attraction. Bonding is preferred, and the decorative cover 220 is fixed to the outer wall of the bottom shell 212 by the adhesive properties of an adhesive (such as epoxy resin adhesive, hot melt adhesive, etc.), covering the threaded hole 212a and ensuring the stability and sealing of the decorative cover 220. In another embodiment, magnetic attraction is used, where a magnet is provided on the decorative cover 220, and a groove is provided on the outer wall of the bottom shell 212. The magnet engages with a magnet or metal part provided in the groove, achieving fixation through magnetic force. These methods not only improve the aesthetics of the electronic product 200 but also enhance its structural stability.

[0041] In one embodiment of the present invention, the outer side wall of the bottom shell 212 is provided with a second slot 212b that communicates with the threaded hole 212a. The decorative cover 220 covers the second slot 212b and is bonded to the bottom wall of the second slot 212b. The screw 2 passes through the threaded hole 212a and is exposed in the second slot 212b.

[0042] In this embodiment, combined with Figure 3 and Figure 5To enhance the overall aesthetics, a second slot 212b is provided on the outer wall of the bottom shell 212, and the decorative cover 220 covers the second slot 212b. It is understood that the second slot 212b is sized to match the decorative cover 220; for example, if the decorative cover 220 is annular, the opening of the second slot 212b will also be annular. The shape and size are not limited here. To ensure the sealing of the decorative cover 220, this application preferably uses an adhesive method (through the adhesion of adhesives such as epoxy resin adhesives, hot melt adhesives, etc.) to connect the bottom wall of the second slot 212b to the decorative cover 220. This arrangement not only improves the aesthetics of the electronic product 200 but also enhances the structural stability.

[0043] In one embodiment of this utility model, the end face of the nut 1 away from the screw 2 is flat, and the shape of the end face is adapted to the groove shape of the first slot 213a.

[0044] In this embodiment, to ensure the connection stability between the upper cover 211 and the bottom shell 212 and effectively prevent the nut 1 from rotating during installation, the shape of the end face of the nut 1 is adapted to the shape of the groove of the first slot 213a. Since the end face of the nut 1 is planar, the tight fit between the nut 1 and the first slot 213a not only increases the contact area but also improves the connection stability, while reducing the possibility of connection failure between the upper cover 211 and the bottom shell 212 due to loosening of the nut 1.

[0045] In one embodiment of the present invention, the electronic product 200 further includes a sealing member 230, which extends along the periphery of the upper cover 211.

[0046] In this embodiment, combined with Figure 7 and Figure 8 To enhance sealing performance, a sealing element 230 is provided along the periphery of the upper cover 211. It should be noted that the sealing element 230 may be made of materials including, but not limited to, TPU (thermoplastic polyurethane elastomer rubber), silicone, polyurethane, polyvinyl chloride, etc., with TPU being the preferred material to ensure a more stable connection between the upper cover 211 and the bottom shell 212. It is understood that the sealing element 230 can be integrally formed on the periphery of the upper cover 211 through overmolding or in-mold injection molding, or the upper cover 211 may have a groove on its periphery, with the sealing element 230 confined within the groove; this is not limited here. The above-mentioned configuration improves the reliability and stability of the electronic product 200.

[0047] In one embodiment of the present invention, the upper cover 211 is provided with a buckle 214 on the side that extends into the bottom shell 212, and a limiting groove 212c is provided on the inner side wall of the bottom shell 212, and the buckle 214 is limited in the limiting groove 212c.

[0048] In this embodiment, combined with Figure 4 To facilitate the installation and removal of the top cover 211 and the bottom shell 212, one side of the top cover 211 that extends into the bottom shell 212 is connected to the bottom shell 212 by screws, and the other side of the top cover 211 that extends into the bottom shell 212 is connected to the bottom shell 212 by snap-fit. Figure 6 It should be noted that the other side of the upper cover 211 that extends into the bottom shell 212 is provided with a buckle 214, which forms a hook. The inner side wall of the bottom shell 212 near the buckle 214 is provided with a limiting groove 212c, and the hook is limited in the limiting groove 212c to prevent the connection between the upper cover 211 and the bottom shell 212 from falling off.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
