Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a camera mounting structure and a sewing machine. Background Technology

[0002] With the development and popularization of AI technology, more and more sewing machines are being equipped with visual recognition modules to capture the operator's hand movements and the state of the cut pieces.

[0003] The existing vision recognition module of sewing machines is a camera, which is installed and fixed on the sewing machine by connecting screws. However, when assembling or disassembling the camera, the connecting screw is not firmly magnetically attracted to the screw, which can easily cause the screw to fall out. This is especially true when the camera is embedded inside the sewing machine, where the connecting screw can fall into the sewing machine, making it not only difficult to find but also potentially damaging the circuitry.

[0004] Therefore, how to prevent the connecting screws from falling off during camera assembly and disassembly has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a camera mounting structure to address the above-mentioned technical problems, so as to solve the technical problem that the connecting screws are easy to fall off when assembling and disassembling the camera.

[0006] The technical solution adopted by this utility model is as follows: a camera mounting structure, including a camera, a mounting base, a connecting bolt, and a spring. The mounting base is provided with a communicating mounting cavity and a mounting hole. The camera is housed in the mounting cavity, and the camera is provided with a connecting hole that mates with the mounting hole. The connecting bolt includes a nut section, a connecting section, and a threaded section arranged sequentially along the axial direction. The connecting section passes through the mounting hole, and the inner diameter of the mounting hole is smaller than the outer diameter of the nut section and the major diameter of the threaded section. The threaded section is threadedly connected to the connecting hole. The spring is sleeved on the connecting section, and one end of the spring abuts against the nut section, while the other end of the spring abuts against the mounting base.

[0007] Preferably, the mounting hole includes an upper receiving hole, a middle connecting hole, and a lower receiving hole arranged sequentially along the axial direction. The inner diameter of the middle connecting hole is smaller than the major diameter of the threaded section but larger than the minor diameter of the threaded section. The inner diameter of the upper receiving hole is larger than the inner diameter of the middle connecting hole. The bottom end of the spring is received in the upper receiving hole, and the inner diameter of the lower receiving hole is larger than the major diameter of the threaded section.

[0008] Preferably, a copper nut that mates with the threaded section is fixedly installed inside the connecting hole.

[0009] The second objective of this utility model is to provide a sewing machine, including the aforementioned camera mounting structure and sewing head, wherein the sewing head is provided with an embedded groove, the mounting base is disposed in the embedded groove of the sewing head, and the top of the sewing head is provided with a disassembly hole, the disassembly hole being located directly above the connecting bolt.

[0010] Preferably, the machine head includes a housing and a cover, the cover being disposed on the outside of the housing, and the cover having a through hole that is directly opposite to the embedded groove.

[0011] Preferably, the mounting base is provided with connecting lugs, which are located on the upper and lower sides of the mounting base and are detachably and fixedly connected to the cover by connecting screws.

[0012] The beneficial effects of this utility model are:

[0013] This invention employs an anti-loosening structure, ensuring that the major diameter of the threaded section of the connecting bolt is larger than the inner diameter of the mounting hole on the mounting base. Once the threaded section passes through the mounting hole via self-tapping, it cannot move axially back through the mounting hole, thus preventing the connecting bolt from coming out of the connecting hole and preventing it from falling or being lost. Simultaneously, a spring is installed between the nut section of the connecting bolt and the mounting base. The elastic force of the spring acting on the nut section can balance the gravity acting on the connecting bolt, thereby moving the threaded section into the mounting hole, which facilitates the movement of the camera within the mounting cavity.

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0036] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] Examples, such as Figures 1-11 As shown, a camera mounting structure includes a camera 100, a mounting base 200, a connecting bolt 300, and a spring 400; wherein, the mounting base 200 has a mounting cavity 210 and a mounting hole 220 formed thereon, and the mounting hole 220 communicates with the mounting cavity 210; the camera 100 is housed in the mounting cavity 210, and a connecting hole 110 is formed on the camera 100 to mate with the mounting hole 220.

[0040] The connecting bolt 300 includes a nut section 310, a connecting section 320, and a threaded section 330, which are sequentially arranged and fixedly connected along the axial direction. The connecting section 320 passes through the mounting hole 220, and the inner diameter of the mounting hole 220 is smaller than the outer diameter of the nut section 310 and the major diameter of the threaded section 330, so as to prevent the connecting bolt 300 from coming out of the mounting hole 220. The spring 400 is sleeved on the connecting section 320, and one end of the spring 400 abuts against the nut section 310, and the other end of the spring 400 abuts against the mounting base 200. The threaded section 330 is threadedly connected in the connecting hole 110 so that the mounting base 200 is fixedly connected to the camera 100.

[0041] This utility model adopts an anti-loosening structure, so that the major diameter of the threaded section 330 of the connecting bolt 300 is larger than the inner diameter of the mounting hole 220 on the mounting base 200. When the threaded section 330 passes through the mounting hole 220 by self-tapping, the threaded section 330 cannot pass through the mounting hole 220 in the opposite direction by axial movement, which can prevent the connecting bolt 300 from coming out of the connecting hole 110, thereby preventing the connecting bolt 300 from falling or being lost. At the same time, a spring 400 is installed between the nut section 310 of the connecting bolt 300 and the mounting base 200. The elastic force of the spring 400 acting on the nut section 310 can balance the gravity acting on the connecting bolt 300, thereby moving the threaded section 330 into the mounting hole 220, which facilitates the movement of the camera 100 in the mounting cavity 210.

[0042] Specific embodiment 1, such as Figures 1-7As shown, a camera mounting structure includes a camera 100, a mounting base 200, a connecting bolt 300, and a spring 400.

[0043] A mounting cavity 210 and a mounting hole 220 are formed on the mounting base 200. The mounting cavity 210 extends horizontally through the mounting base 200, and the mounting hole 220 is formed vertically at the top of the mounting base 200, with the bottom end of the mounting hole 220 communicating with the mounting cavity 210.

[0044] The camera 100 is housed in the mounting cavity 210, and a connecting hole 110 is formed on the top of the camera 100 to mate with the mounting hole 220. That is, after the camera 100 is moved into place in the mounting base 200, the mounting hole 220 is located directly above the connecting hole 110.

[0045] It should be noted that the horizontal positioning of the camera 100 and the mounting base 200 can adopt any known positioning method. For example, a first positioning surface is formed at the front end of the mounting base 200, and a second positioning surface is formed at the front end of the camera 100. When the camera 100 moves in the mounting cavity 210 of the mounting base 200, after the first positioning surface and the second positioning surface are tightly fitted, the camera 100 moves into place in the mounting base 200, and the mounting hole 220 is exactly located above the connecting hole 110.

[0046] The connecting bolt 300 includes a nut section 310, a connecting section 320, and a threaded section 330 that are sequentially arranged and fixedly connected along the axial direction. That is, the connecting bolt 300 includes a nut section 310, a connecting section 320, and a threaded section 330. The nut section 310, the connecting section 320, and the threaded section 330 are arranged coaxially, and the connecting section 320 is fixedly connected between the nut section 310 and the threaded section 330.

[0047] The mounting hole 220 includes an upper receiving hole 221, a middle connecting hole 222, and a lower receiving hole 223 arranged sequentially along the axial direction. That is, the mounting hole 220 includes an upper receiving hole 221, a middle connecting hole 222, and a lower receiving hole 223. The upper receiving hole 221, the middle connecting hole 222, and the lower receiving hole 223 are coaxially arranged, and the middle connecting hole 222 is fixedly connected between the upper receiving hole 221 and the lower receiving hole 223. The inner diameter of the upper receiving hole 221 is larger than the inner diameter of the middle connecting hole 222, so as to form an upper stop surface that cooperates with the spring 400 between the upper receiving hole 221 and the middle connecting hole 222; the inner diameter of the lower receiving hole 223 is larger than the inner diameter of the middle connecting hole 222, so as to form a lower stop surface that cooperates with the threaded section 330 of the connecting bolt 300 between the middle connecting hole 222 and the lower receiving hole 223.

[0048] The radial dimension of the connecting section 320 is less than or equal to the inner diameter of the central connecting hole 222, and the axial dimension of the connecting section 320 is greater than the axial dimension of the central connecting hole 222. The connecting section 320 passes through the central connecting hole 222 of the connecting hole 110 and is used to guide the axial movement of the connecting bolt 300.

[0049] The major diameter of the threaded segment 330 is larger than the inner diameter of the central connecting hole 222, and the minor diameter of the threaded segment 330 is smaller than the inner diameter of the central connecting hole 222. This is so that after the threaded segment 330 passes through the central connecting hole 222 by self-tapping, when the threaded segment 330 moves axially, the lower end face of the central connecting hole 222 (that is, the lower stop face) can form a stop engagement with the external thread on the threaded segment 330, which prevents the threaded segment 330 from moving further axially in the connecting hole 110, and prevents the threaded segment 330 from passing through the central connecting hole 222 in the opposite direction by axial movement, thereby preventing the connecting bolt 300 from coming out of the mounting hole 220.

[0050] The major diameter of the threaded section 330 is smaller than the inner diameter of the lower receiving hole 223, and the axial dimension of the threaded section 330 is less than or equal to the axial dimension of the lower receiving hole 223, so that the threaded section 330 can be completely received in the lower receiving hole 223 of the mounting hole 220 under the elastic force of the spring 400, so as to ensure that the camera 100 can smoothly enter and exit the mounting cavity 210 of the mounting base 200.

[0051] The inner diameter of the upper receiving hole 221 is larger than the inner diameter of the middle connecting hole 222, and the inner diameter of the upper receiving hole 221 is smaller than the outer diameter of the nut section 310, so that after the bottom end of the spring 400 is received in the upper receiving hole 221, the bottom end of the spring 400 can abut against the mounting base 200, that is, the bottom end of the spring 400 abuts against the upper stop surface.

[0052] The bottom end of the spring 400 is housed in the upper receiving hole 221, and the spring 400 is sleeved on the outside of the connecting section 320. The top end of the spring 400 abuts against the nut section 310, and the bottom end of the spring 400 abuts against the mounting base 200.

[0053] The threaded section 330 is threaded into the connecting hole 110 to fix the mounting base 200 to the camera 100.

[0054] Preferably, a copper nut 120 is fixedly installed in the connection hole 110. The copper nut 120 is fixedly connected to the connection hole 110 of the camera 100 by a hot melt embedding method, and the copper nut 120 is threadedly connected to the threaded section 330 at the bottom of the connecting bolt 300 to ensure the stability of the connection between the connecting bolt 300 and the camera 100, thereby improving the service life of the camera 100.

[0055] It should be noted that the mounting base 200 is made of plastic, and the outer layer of the camera 100 is also made of plastic.

[0056] Specific embodiment 2, such as Figures 1-11 As shown, a sewing machine includes the aforementioned camera mounting structure and a sewing head 500. An embedded groove 550 is provided on the sewing head 500, and the mounting base 200 is installed in the embedded groove 550. A disassembly hole 530 is provided on the top of the sewing head 500. The disassembly hole 530 is located directly above the connecting bolt 300, so that the operator can tighten or loosen the connecting bolt 300 between the mounting base 200 and the camera 100 without disassembling the sewing head 500, thereby achieving quick assembly and disassembly of the camera 100.

[0057] Preferably, the machine head 500 includes a housing 510 and a cover 520. The housing 510 has an embedded groove 550 and a disassembly hole 530 formed on it. The cover 520 is completely covered on the outside of the housing 510, and a through hole 540 is opened on the cover 520 that is directly opposite to the embedded groove 550.

[0058] Specifically, the mounting base 200 can be fixed in the recessed groove 550 using any known detachable connection structure. The following is a detailed description of one such structure as an example: Two connecting ear plates 230 are formed on the mounting base 200, positioned one above the other on the upper and lower sides of the mounting base 200. One connecting ear plate 230 is located above the mounting cavity 210, and the other is located below the mounting cavity 210. Two connecting posts are integrally formed on the side of the cover 520 facing the housing 510, and the two connecting posts correspond one-to-one with the two connecting ear plates 230. The connecting ear plates 230 are detachably fixed to the connecting posts via connecting screws, thereby detachably fixing the mounting base 200 to the cover 520.

[0059] The working process of the camera mounting structure of this utility model is as follows:

[0060] When the bottom end of the connecting bolt 300 is unscrewed from the connecting hole 110 of the camera 100, the spring 400 is in a compressed state. The elastic force of the spring 400 will counteract the weight of the connecting bolt 300. The elastic force will make the connecting bolt 300 stand above the camera 100, and the camera 100 can be pushed out for easy replacement or removal for inspection.

[0061] After the camera 100 is placed into the mounting base 200 in the form of a module, the bottom end of the connecting bolt 300 is passed through the mounting base 200 by self-tapping and the bottom end of the connecting bolt 300 is threaded into the connecting hole 110 of the camera 100, thereby fixing the camera 100. At this time, the spring 400 is in the mounting hole 220 of the mounting base 200 and is in a compressed state.

[0062] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0063] This invention ensures that the connecting bolt remains in the mounting hole of the mounting base, preventing screws from falling off or being lost during installation due to weak magnetic attraction between the screwdriver and the connecting bolt. It also solves the problem of aligning the connecting bolt with the mounting hole, enabling rapid installation.

[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
