Description

Technical Field

[0001] This invention relates to the field of scanning device technology, and more specifically, to a ring-type device and a disassembly tool. Background Technology

[0002] As a small, finger-worn device, the ring-shaped device needs to accommodate the diverse size requirements of various users. Currently, ring-shaped devices typically provide a standard-sized opening through a sliding groove structure, and then offer multiple ring sleeves of different sizes with standard-sized sliders as a solution. After selecting the appropriate size ring sleeve, users align the slider with the groove to install the ring sleeve and then wear it.

[0003] However, the assembly of the slot is ensured by the frictional resistance between the material of the ring sleeve and the slide of the device. Therefore, due to the wear and tear caused by frequent insertion and removal of the ring sleeve and the aging and deterioration of the material of the ring sleeve over time, the reliability of the connection between the main body of the ring-type device and the ring sleeve will decrease, which may lead to problems such as the detachment of the main body of the device. Summary of the Invention

[0004] The main objective of this invention is to provide a ring-type device and a disassembly tool to solve the problem of low reliability in the connection between the main body of the ring-type device and the ring sleeve in the prior art.

[0006] Furthermore, the main body is provided with an installation groove and a first installation opening, both of which are connected to the installation groove; the ring sleeve also includes an installation slider, which enters the installation groove through the first installation opening and is slidably disposed within the installation groove; the anti-detachment structure is connected to the installation slider.

[0009] Furthermore, the anti-detachment part has a plate-like structure, and the plate-like structure is arc-shaped in the direction from the first end to the second end of the anti-detachment part; or, the cross-section of the anti-detachment part perpendicular to the center line of the second mounting opening is T-shaped.

[0010] Furthermore, the anti-detachment main body is a parallelogram structure, the sidewall of the parallelogram structure is connected to the connecting part, and the parallelogram structure has a first end face and a second end face that are arranged opposite to each other along the extension direction of the center line of the second mounting opening; the first opening extends from the first end face to the second end face.

[0011] Furthermore, the anti-detachment structure includes multiple anti-detachment parts, which are arranged at intervals around the connecting part.

[0012] Furthermore, the connecting parts are made of flexible materials.

[0013] Furthermore, the anti-detachment structure and the mounting slider are integrally molded.

[0014] Furthermore, the main body has a first connecting hole, the first end of which is connected to the mounting groove, and the second end of which extends to the stop end face to form a second mounting opening; the first connecting hole is a circular hole, and the diameter of the circular hole remains unchanged along the axial direction; a second connecting hole is provided between the first connecting hole and the mounting groove, and the area of ​​the cross section of the second connecting hole perpendicular to its axial direction gradually decreases in the direction from the mounting groove to the first connecting hole.

[0015] Furthermore, the main body is provided with a mounting groove, the bottom of which is a stop end face; after the anti-detachment structure abuts against the stop end face, at least a portion of the anti-detachment structure is located within the mounting groove.

[0016] Furthermore, the finger ring sleeve includes a finger ring sleeve body for wearing on the finger, and the finger ring sleeve body has a first connecting end and a second connecting end arranged sequentially along its circumferential direction, and both the first connecting end and the second connecting end are provided with mounting sliders; wherein, the anti-detachment structure, the mounting groove and the mounting slider are arranged in pairs.

[0017] According to another aspect of the present invention, a disassembly tool is provided, applicable to the aforementioned ring-type device. The disassembly tool includes a disassembly tool body having a disassembly port and a compression channel communicating with the disassembly port. When disassembling the ring sleeve of the ring-type device, the disassembly tool body is placed on an anti-detachment structure, so that the anti-detachment structure enters the disassembly tool body through the disassembly port and is located in the compression channel after being compressed and contracted, so that the compressed anti-detachment structure exits the second mounting opening of the main body of the ring-type device.

When the disassembly tool body is covered on the anti-detachment structure, each anti-detachment part is located in the corresponding receiving interval. When the disassembly tool body is rotated, the anti-detachment part is squeezed by the ratchet teeth and retracts into the compression channel. Alternatively, the inner wall of the second annular portion forms a compression channel.

When the main body and the ring sleeve are assembled, the anti-detachment structure passes through the second mounting opening. Since at least a portion of the anti-detachment structure is made of a flexible material, it is compressed and deformed when passing through the second mounting opening to pass through it. After passing through the second mounting opening, the anti-detachment structure returns to its original deformation and abuts against the stop end face of the main body having the second mounting opening. In this way, the anti-detachment structure cannot return from the second mounting opening, and the ring sleeve is reliably connected to the main body, solving the problem of low reliability of the connection between the main body and the ring sleeve in the prior art.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] This invention provides a ring-type device; please refer to [reference needed]. Figures 1 to 8 The device includes a main body 10 and a ring sleeve 20. The ring sleeve 20 is connected to the main body 10. The main body 10 is provided with a second mounting opening 12. The ring sleeve 20 includes an anti-detachment structure 22. At least a portion of the anti-detachment structure 22 is made of a flexible material so that the anti-detachment structure 22 is squeezed through the second mounting opening 12 and deforms after passing through the second mounting opening 12 to abut against the stop end face 14 of the main body 10 having the second mounting opening 12.

[0038] The ring-type device of the present invention includes a main body 10 and a ring sleeve 20, which is connected to the main body 10. The main body 10 is provided with a second mounting opening 12. The ring sleeve 20 includes an anti-detachment structure 22. When the main body 10 and the ring sleeve 20 are assembled, the anti-detachment structure 22 passes through the second mounting opening 12. Since at least a portion of the anti-detachment structure 22 is made of a flexible material, it is compressed and deformed when it passes through the second mounting opening 12 to pass through it. After the anti-detachment structure 22 passes through the second mounting opening 12, it returns to its original shape and abuts against the stop end face 14 of the main body 10 with the second mounting opening 12. In this way, the anti-detachment structure 22 cannot return from the second mounting opening 12, and the ring sleeve 20 is reliably connected to the main body 10. This solves the problem of low reliability of the connection between the main body and the ring sleeve in the prior art. Furthermore, the ring-type device has a simple structure, low production cost, and is easy to assemble.

[0039] Specifically, the ring-type device is a scanner, with the main body 10 used to scan barcodes, QR codes, etc.; and the ring sleeve 20 used to be worn on the finger.

[0040] It should be noted that at least part of the anti-detachment structure 22 is made of a flexible material, wherein the flexible material refers to a material that deforms when compressed and can recover its deformation when the compression is removed.

[0041] In this embodiment, the main body 10 is provided with a mounting groove 13 and a first mounting opening 11. The first mounting opening 11 and the second mounting opening 12 are both connected to the mounting groove 13. The ring sleeve 20 also includes a mounting slider 21. The mounting slider 21 enters the mounting groove 13 through the first mounting opening 11 and is slidably disposed in the mounting groove 13. The anti-detachment structure 22 is connected to the mounting slider 21.

[0042] In practice, the mounting slider 21 enters the mounting groove 13 through the first mounting opening 11 and slides within the mounting groove 13. Since the anti-detachment structure 22 is connected to the mounting slider 21, during the assembly of the main body 10 and the ring sleeve 20, the anti-detachment structure 22 passes through the first mounting opening 11 before the mounting slider 21. The anti-detachment structure 22 and the mounting slider 21 slide along the extension direction of the mounting groove 13. After the anti-detachment structure 22 passes through the second mounting opening 12, the mounting slider 21 is inserted into the mounting groove 13. Therefore, the sliding cooperation between the mounting slider 21 and the mounting groove 13 guides the anti-detachment structure 22, causing it to pass through the second mounting opening 12. Furthermore, after the main body 10 and the ring sleeve 20 are assembled, the mounting slider 21 inserted into the mounting groove 13 increases the assembly stability of the main body 10 and the ring sleeve 20.

[0043] In this embodiment, the anti-detachment structure 22 includes a connecting part 23 and an anti-detachment part 24. The anti-detachment part 24 is connected to the mounting slider 21 through the connecting part 23. The anti-detachment part 24 is made of flexible material. The first end of the anti-detachment part 24 is connected to the connecting part 23, and the second end of the anti-detachment part 24 is a free end that extends in a direction away from the connecting part 23.

[0044] In specific implementation, the connecting part 23 serves to connect the anti-detachment part 24 and the mounting slider 21; the anti-detachment part 24 is made of flexible material so that the anti-detachment part 24 can deform, thereby shrinking and deforming under pressure, and will return to its original shape after passing through the second mounting opening 12, thereby achieving the effect of preventing the ring sleeve 20 from falling off the main body 10; and setting the second end of the anti-detachment part 24 as a free end and extending it in a direction away from the connecting part 23 facilitates the deformation of the anti-detachment part 24.

[0045] In this embodiment, the anti-detachment part 24 is a plate-shaped structure, and the plate-shaped structure is arc-shaped in the direction from the first end to the second end of the anti-detachment part 24; or, the cross section of the anti-detachment part 24 perpendicular to the center line of the second mounting opening 12 is T-shaped.

[0046] In practice, the anti-detachment part 24 is arranged in an arc shape or a T-shaped cross section, which makes it easier for the anti-detachment part 24 to deform when it is squeezed through the second mounting opening 12. The arc shape moves towards the connecting part 23 when squeezed, forming a cylindrical structure that matches the circular second mounting opening. The bottom of the T-shaped structure is narrower and is connected to the connecting part 23. When squeezed, it will be compressed. Both of these structures can make the anti-detachment part 24 shrink in the radial direction of the second mounting opening 12 and pass smoothly through the second mounting opening 12.

[0047] In other embodiments, the anti-detachment structure 22 includes a connecting portion 23 and an anti-detachment portion 24, the anti-detachment portion 24 being connected to the mounting slider 21 via the connecting portion 23; the anti-detachment portion 24 is made of a flexible material; the anti-detachment portion 24 includes an anti-detachment main body and a first opening, the first opening being disposed on the anti-detachment main body; and / or, a second opening is formed between the anti-detachment main body and the connecting portion 23.

[0048] In specific implementation, the setting of the first opening and the second opening ensures that the anti-detachment part 24 will change shape when squeezed, so that the anti-detachment part 24 shrinks in the radial direction of the second mounting opening 12, so that the anti-detachment part 24 can pass through the second mounting opening 12 smoothly, avoiding the anti-detachment part 24 being unable to pass through the second mounting opening 12 due to insufficient deformation.

[0049] In other embodiments, the anti-detachment main body is a parallelogram structure, the sidewall of the parallelogram structure is connected to the connecting part 23, and the parallelogram structure has a first end face and a second end face that are arranged opposite to each other along the extension direction of the center line of the second mounting opening 12; the first opening extends from the first end face to the second end face.

[0050] In specific implementation, a first opening is provided on the first end face to the second end face of the parallelogram structure, so that the anti-detachment main body has a compression space when compressed. The flexible material of the anti-detachment main body is concentrated at the first opening, reducing the overall volume of the anti-detachment part 24, thereby allowing the anti-detachment part 24 to pass through the second installation opening 12.

[0051] In this embodiment, the anti-detachment structure 22 includes a plurality of anti-detachment parts 24, which are arranged at intervals around the connecting part 23.

[0052] In practice, the multiple anti-detachment parts 24 are arranged around the connecting part 23 at intervals, which saves the material used to make the anti-detachment parts 24. Moreover, the multiple anti-detachment parts 24 have a smaller cross-sectional area in the circumferential direction of the anti-detachment structure 22, so that the multiple anti-detachment parts 24 are easier to be squeezed and deformed. Furthermore, when the multiple anti-detachment parts 24 abut against the stop end face 14 of the main body part 10, the anti-detachment parts 24 are further prevented from returning to the mounting groove 13, ensuring the reliability of the connection between the ring sleeve 20 and the main body part 10.

[0053] In this embodiment, the connecting portion 23 is made of a flexible material. This arrangement allows the connecting portion 23 to deform under pressure when the anti-detachment portion 24 is squeezed, making the anti-detachment structure 22 easier to pass through the second mounting opening 12.

[0054] In this embodiment, the anti-detachment structure 22 and the mounting slider 21 are integrally formed. This design enhances the connection reliability between the anti-detachment structure 22 and the mounting slider 21, and facilitates molding, reducing production costs.

[0055] In other embodiments, such as Figure 7 As shown, the main body 10 has a first connecting hole 15. The first end of the first connecting hole 15 communicates with the mounting groove 13, and the second end of the first connecting hole 15 extends to the stop end face 14 to form a second mounting opening 12. The first connecting hole 15 is a circular hole, and its diameter remains constant along the axial direction. A second connecting hole 16 is provided between the first connecting hole 15 and the mounting groove 13. From the mounting groove 13 to the first connecting hole 15, the area of ​​the cross-section of the second connecting hole 16 perpendicular to its axial direction gradually decreases. It should be noted that the axial direction of the circular hole is the same as the axial direction of the first connecting hole 15; the axial direction in which the area of ​​the cross-section of the second connecting hole 16 gradually decreases perpendicular to its axial direction is the same as the axial direction of the second connecting hole 16.

[0056] In practice, before the anti-detachment structure 22 passes through the second mounting opening 12, it first passes through the second connecting hole 16. Because the cross-sectional area of ​​the second connecting hole 16 perpendicular to its axial direction gradually decreases, the anti-detachment structure 22 is compressed. After being compressed and deformed, the anti-detachment structure 22 enters the first connecting hole 15, finally reaches and passes through the second mounting opening 12, and after recovering its deformation, abuts against the stop end face 14. This arrangement allows the anti-detachment structure 22 to smoothly pass through the second mounting opening 12 and lock with the main body 10.

[0057] In other embodiments, such as Figure 8 As shown, the main body 10 is provided with a mounting groove 17, and the bottom of the mounting groove 17 is a stop end face 14; after the anti-detachment structure 22 abuts against the stop end face 14, at least a portion of the anti-detachment structure 22 is located in the mounting groove 17.

[0058] In specific implementation, the mounting groove 17 is used to accommodate the anti-detachment structure 22, and the bottom of the mounting groove 17 is the stop end face 14. After the anti-detachment structure 22 returns to its shape, it can abut against the stop end face 14, thus achieving the anti-detachment effect of the ring sleeve 20; and at least part of the anti-detachment structure 22 is located in the mounting groove 17 to avoid damage to the anti-detachment structure 22 during use.

[0059] In this embodiment, the finger ring sleeve 20 includes a finger ring sleeve body 25 for wearing on a finger. The finger ring sleeve body 25 has a first connecting end and a second connecting end arranged sequentially along its circumferential direction. Both the first connecting end and the second connecting end are provided with mounting sliders 21. The anti-detachment structure 22, the mounting groove 13 and the mounting slider 21 are arranged in pairs.

[0060] In practice, mounting sliders 21 are provided on both the first and second connecting ends of the ring sleeve body 25, so that both ends of the ring sleeve body 25 are fixed to the main body 10, thereby enhancing the anti-fall-off effect.

[0061] Specifically, the ring sleeve body 25 is arc-shaped. After the ring sleeve 20 is fixedly connected to the body part 10, the shape of the space enclosed between the ring sleeve 20 and the body part 10 is adapted to the finger.

[0062] In practical implementation, using this ring-type device, when the user selects to install the ring sleeve 20, they only need to insert the mounting slider 21 on the ring sleeve 20 into the mounting groove 13 on the main body 10 at the corresponding angle and push it all the way down. When the user installs the mounting slider 21 to the bottom of the mounting groove 13, the petal-shaped opening and closing structure formed by the multiple anti-detachment parts 24 of the anti-detachment structure 22 will contract into a compressed state under the action of the second connecting hole 16 and the first connecting hole 15, and its outer diameter will decrease so that it can pass through the first connecting hole 15. After the anti-detachment structure 22 has completely passed through the first connecting hole 15, the petal-shaped opening and closing structure is no longer squeezed by the hole wall and returns to the open state under its own elasticity, and its outer diameter increases, thereby achieving the locking of the ring sleeve 20 and the main body 10. When the ring sleeve 20 is subjected to external force and tends to move outward along the mounting groove 13, the multiple anti-detachment parts 24 will cause severe interference with the first connecting hole 15 when the diameter of the petal-shaped opening and closing structure is larger than that of the first connecting hole 15 in the non-pressurized state. This provides great damping to prevent the mounting slider 21 from moving in the detachment direction.

[0063] The present invention also provides a disassembly tool applicable to the ring-type device in the above embodiments. Please refer to [link / reference needed]. Figure 9 The disassembly tool includes a disassembly tool body 30, which has a disassembly port 31 and a compression channel 32 connected to the disassembly port 31. When disassembling the ring sleeve 20 of the ring-type device, the disassembly tool body 30 is placed on the anti-detachment structure 22 so that the anti-detachment structure 22 enters the disassembly tool body 30 through the disassembly port 31 and is located in the compression channel 32 after being compressed and contracted, so that the compressed anti-detachment structure 22 exits the second mounting opening 12 of the main body 10 of the ring-type device.

[0064] In practice, after the anti-detachment structure 22 is covered by the disassembly tool body 30, it enters the compression channel 32. Under the compression, the anti-detachment structure 22 shrinks to a size that can pass through the second mounting opening 12, so that the anti-detachment structure 22 can enter the mounting groove 13 through the second mounting opening 12, thereby causing the mounting slider 21 of the ring sleeve 20 to slide out along the mounting groove 13 of the main body 10 of the ring-type device, thus realizing the disassembly between the ring sleeve 20 and the main body 10.

[0065] In this embodiment, the diameter of the extrusion channel 32 is equal to the diameter of the second mounting opening 12. This arrangement ensures that the diameter of the anti-detachment structure 22, which is extruded through the extrusion channel 32, is equal to the diameter of the second mounting opening 12, allowing it to retract into the mounting groove 13 through the second mounting opening 12.

[0066] In this embodiment, the disassembly tool body 30 includes an annular sidewall 33, which has a first annular portion 34 and a second annular portion 35 arranged sequentially along its axial direction. The first end of the first annular portion 34 forms a disassembly opening 31, and the second end of the first annular portion 34 is connected to the second annular portion 35. The wall thickness of the first annular portion 34 gradually decreases from the second end to the first end. The wall thickness of the second annular portion 35 remains unchanged in its axial direction, and the wall thickness of the second end of the first annular portion 34 is equal to the wall thickness of the second annular portion 35.

[0067] In practice, during the process of covering the disassembly tool body 30 with the anti-detachment structure 22, the wall thickness of the first annular portion 34 gradually decreases from the second end to the first end, causing the anti-detachment structure 22 to be gradually compressed to a size that can pass through the second mounting opening 12. Furthermore, the smaller wall thickness at the first end of the first annular portion 34 facilitates the insertion of the disassembly tool between the anti-detachment structure 22 and the groove wall of the mounting groove 17, thus reducing friction. The outer diameter of the disassembly tool body 30 is smaller than the inner diameter of the mounting groove 17.

[0068] In this embodiment, a plurality of ratchet teeth 36 are provided on the inner wall of the second annular portion 35. The plurality of ratchet teeth 36 are spaced apart along the circumferential direction of the second annular portion 35. The end of the plurality of ratchet teeth 36 away from the inner wall of the second annular portion 35 forms a compression channel 32. There is a receiving interval 37 between two adjacent ratchet teeth 36. The plurality of receiving intervals 37 are provided one-to-one with the plurality of anti-detachment parts 24 of the anti-detachment structure 22. When the disassembly tool body 30 is covered on the anti-detachment structure 22, each anti-detachment part 24 is located in the corresponding receiving interval 37. When the disassembly tool body 30 is rotated, the anti-detachment part 24 is squeezed by the ratchet teeth 36 and retracts into the compression channel 32. Alternatively, the inner wall of the second annular portion 35 forms the compression channel 32.

[0069] In practice, the arrangement of multiple ratchet teeth 36 allows each anti-detachment part 24 to be accommodated in the corresponding accommodating interval 37 after entering the second annular part 35. When the disassembly tool body 30 is rotated, the multiple ratchet teeth 36 act on the multiple anti-detachment parts 24, causing the multiple anti-detachment parts 24 to gradually shrink along the side walls of the multiple ratchet teeth 36, and finally clamp between the ends of the multiple ratchet teeth 36 that are away from the inner wall of the second annular part 35, thereby achieving the effect of compressing the multiple anti-detachment parts 24.

[0070] Specifically, the ratchet 36 has a first sidewall and a second sidewall that are arranged opposite to each other along the circumferential direction of the second annular portion 35. Both the first sidewall and the second sidewall are arc-shaped surfaces. The first sidewall is recessed toward the center of the ratchet 36, and the second sidewall is protruding toward the direction away from the center of the ratchet 36. When the disassembly tool body 30 is rotated, the anti-detachment part 24 is squeezed by the first sidewall, causing the anti-detachment part 24 to gradually shrink into the squeezing channel 32, and finally pass through the second mounting opening 12.

[0071] This application is based on the combination of the mounting slider 21 and the deformable structure (i.e. the anti-detachment structure 22). When the main body 10 and the ring sleeve 20 are separated, the short-distance directional relative movement that will inevitably occur in the early stage causes the anti-detachment structure 22 to deform accordingly. As a result, when the ring sleeve continues to move in the detachment direction, it is subjected to the additional interference generated at the deformation point, which forms an obstacle to the movement and provides a large amount of frictional damping to prevent accidental detachment.

[0072] This application solves the following technical problems:

[0073] This solves the problem of low connection reliability between the main body of the ring-type device and the ring sleeve caused by frequent plugging and unplugging of the ring-type device; it also solves the problem of reduced connection reliability caused by aging and deterioration of the ring-type device's own materials.

[0074] This application has the following beneficial effects:

[0075] The design incorporates an anti-detachment structure 22 that deforms during retraction. When the ring sleeve 20 shows signs of detachment and begins to slide backward along the mounting groove 13, the anti-detachment structure 22 is prevented from continuing to slide due to the obstruction of the stop end face 14 of the ring-type device, thus preventing the ring sleeve 20 from separating and preventing the device from falling off. Production costs are low, requiring only the corresponding shape to be machined on the mold of the ring sleeve 20, allowing for mass production. Assembly is simple; besides sliding the mounting slider 21 and the anti-detachment structure 22 on the ring sleeve 20 into the mounting groove 13 of the main body 10, no additional operation is required to achieve the anti-detachment effect. Long-term stability is good, and the anti-detachment effect is unaffected by factors such as the device's operating environment and lifespan.

[0076] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0077] The ring-type device of the present invention includes a main body 10 and a ring sleeve 20, which is connected to the main body 10. The main body 10 is provided with a second mounting opening 12. The ring sleeve 20 includes an anti-detachment structure 22. When the main body 10 and the ring sleeve 20 are assembled, the anti-detachment structure 22 passes through the second mounting opening 12. Since at least a portion of the anti-detachment structure 22 is made of a flexible material, it is compressed and deformed when it passes through the second mounting opening 12 to pass through it. After the anti-detachment structure 22 passes through the second mounting opening 12, it returns to its original shape and abuts against the stop end face 14 of the main body 10 with the second mounting opening 12. In this way, the anti-detachment structure 22 cannot return from the second mounting opening 12, and the ring sleeve 20 is reliably connected to the main body 10. This solves the problem of low reliability of the connection between the main body and the ring sleeve in the prior art. Furthermore, the ring-type device has a simple structure, low production cost, and is easy to assemble.
