Description

Technical Field

[0001] This invention relates to the field of pressure-holding equipment, and more particularly to a pressure-holding device. Background Technology

[0002] Existing pressure-holding devices are either one pressure head per cavity or a single carrier with multiple pressure heads. Regardless of the type, these devices are typically fixed inside the cavity and are difficult to disassemble. This makes disassembly and adjustment difficult for workers, hindering the adjustment of the pressure-holding position of the fixture. Furthermore, online adjustments are required during debugging, impacting production efficiency.

[0003] Therefore, there is an urgent need for a pressure-holding device that is detachably connected to acupoints for offline adjustment to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure-holding device that is detachably connected to acupoints for offline adjustment.

[0005] To achieve the above objectives, the pressure-holding device of the present invention includes a base for detaching from and attaching to an external acupoint, a carrier for placing a product, and a pressing assembly for applying pressure to the product. The base includes a horizontally arranged base plate and a vertically arranged upright plate on the base plate. The back of the upright plate and the bottom surface of the base plate each have a first magnetic attraction structure for adsorbing onto the external acupoint. The upright plate and / or the base plate also include a through-hole first connecting hole. The base is detachably connected to the external acupoint through the first connecting hole and a connector. The carrier is detachably mounted on the upper surface of the base plate and has a contoured groove for placing the product. The pressing assembly is slidably mounted on the upright plate and includes a pressure rod located above the carrier for applying pressure to the product.

[0006] Compared with the prior art, the pressure-holding device of the present invention has a base, and the pressing component and carrier are all mounted on the base. Therefore, by simply removing the base, the pressing component and carrier can be removed from the external acupoint together for convenient offline debugging. The back of the upright plate and the bottom surface of the base each have a first magnetic attraction structure for adhering to the external acupoint. The external acupoint has a second magnetic attraction structure that attracts the first magnetic attraction structure. The first connecting hole of the base is also detachably connected to the external acupoint through a connector. When installing the present invention back into the external acupoint, it is only necessary to adsorb the base onto the external acupoint for temporary fastening. Then, the first connecting hole and the acupoint are connected through the connector to achieve secondary fastening. This makes installation convenient and quick. When disassembling the present invention from the external acupoint, it is only necessary to use a tool to remove the connector, release the first layer of fixation between the base and the external acupoint, and then apply force to the base to overcome the magnetic attraction between the base and the external acupoint, so that the entire present invention can be removed, ensuring the safety of disassembly. The carrier can be detachably mounted on the base. When debugging offline, the position of the carrier can be adjusted. Different carriers can also be replaced and the position of the carrier can be adjusted according to different products.

[0026] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please see Figures 1 to 4 The pressure-holding device of the present invention includes a base 1 for attaching and detaching from external acupoints, a carrier 2 for placing a product, and a pressing assembly for applying pressure to the product. The base 1 includes a horizontally arranged bottom plate 11 and a vertically arranged upright plate 12. The bottom plate 11 and the upright plate 12 form an L-shaped structure. The back surface of the upright plate 12 and the bottom surface of the bottom plate 11 each have a first magnetic attraction structure 13 for adsorbing onto the external acupoint. Specifically, the back surface of the upright plate 12 and the bottom surface of the bottom plate 11 are recessed with a plurality of first receiving grooves for accommodating the first magnetic attraction structure 13. It is understood that the external acupoint has a second magnetic attraction structure 201 aligned with the first magnetic attraction structure 13. It is understood that the first magnetic attraction structure 13 and the second magnetic attraction structure 201 are magnets of opposite polarity, or one is a magnetic metal and the other is a magnet, and therefore are not limited thereto.

[0028] Please continue reading. Figures 1 to 4The upright plate 12 and the base plate 11 also include a through-hole 14. It is understood that a second connecting hole (not shown in the figure) is provided within the acupoint, aligned with the first connecting hole 14. The first connecting hole 14 is detachably connected to the acupoint via a connector (not shown in the figure). For example, when the base 1 is attached to the acupoint, the first connecting hole 14 and the second connecting hole are aligned. At this time, the first connecting hole 14 and the second connecting hole can be directly fixed using the connector 202. For example, the connector can be a bolt or screw.

[0029] With the help of the first magnetic attraction structure 13 and the second magnetic attraction structure 201, the base 1 can be quickly attached to the acupoint during installation, so as to facilitate subsequent connection operations. When disassembly is required, since the base 1 is attached to the acupoint and will not fall off immediately, after the connector is removed, the base 1 can be removed from the acupoint with a little force, thus ensuring the convenience of installation and the safety of disassembly.

[0030] Please continue reading. Figures 1 to 4 The carrier 2 is detachably mounted on the upper surface of the base plate 11, and the carrier 2 has a contoured groove 221 for inserting the product. Specifically, the product in this embodiment is an earphone half-shell, and the outer contour of the contoured groove 221 matches the earphone half-shell. It is understood that the top of the product protrudes from the contoured groove 221 to be pressed by the pressing assembly.

[0031] Please continue reading. Figures 1 to 4 The pressing assembly is slidably mounted on the upright plate 12, and is located above the carrier 2. The pressing assembly includes a pressure bar for pressing the product, with the pressure bar facing the product on the carrier 2. More specifically, as follows:

[0032] Please see Figures 1 to 4 Preferably, a reinforcing rib 16 is also connected between the base plate 11 and the upright plate 12, which enhances the stability of the connection between the upright plate 12 and the base plate 11.

[0033] Please see Figures 1 to 4Preferably, a support pad 17 is also stacked on the upper surface of the base plate 11. The support pad 17 is horizontally positioned and detachably mounted on the base plate 11. Specifically, the support pad 17 has several first mounting holes 171, and the base plate 11 has several second mounting holes (not shown in the figure) that are directly opposite the first mounting holes 171 in the vertical direction. The first mounting holes 171 and the second mounting holes are connected by connectors 174. Specifically, the first mounting holes 171 are located on both sides of the support pad 17. The carrier 2 is detachably mounted on the upper surface of the support pad 17. Specifically, the support pad 17 has a groove 172 in the middle for mounting the carrier 2. A third magnetic structure 173 is installed on at least one side of the groove wall of the groove 172, and a fourth magnetic structure 26 that attracts the third magnetic structure 173 is provided on the outer wall of the carrier 2. The carrier 2 is attracted to the groove 172 by the mutual attraction of the third magnetic structure 173 and the fourth magnetic structure 26. It is understood that the outer contour of the groove 172 matches the outer contour of the carrier 2. For example, in this embodiment, the third magnetic structure 173 is located on the left and rear sides of the groove 172, and correspondingly, the fourth magnetic structure 26 is located on the left and rear sides of the carrier 2. It is understood that the third magnetic structure 173 can be simultaneously or individually located on all five surfaces of the groove 172, including the front, back, left, right, and bottom, and is not limited thereto. It is understood that both the third magnetic structure 173 and the fourth magnetic structure 26 are magnets. The carrier 2 is supported by the support plate 17. When disassembly is required, the support plate 17 can be removed from the base 1; or, when the position of the carrier 2 needs to be adjusted, the support plate 17 can be adjusted to a suitable position and then reconnected to the base 1. Understandably, after removing the support plate 17, the carrier 2 is attached to the groove 172, and force can be applied to remove the carrier 2 from the groove 172 for replacement. Therefore, the carrier 2 has the convenience of quick installation and replacement.

[0034] See Figures 5 to 7The carrier 2 includes a base 21, a mounting base 22, a first cover plate 23, a second cover plate 24, and an inner support 25. The base 21 is detachably mounted on the upper surface of the base plate 11, specifically, the base 21 is detachably mounted in the groove 172. The mounting base 22 is detachably connected to the base 21. The front and upper surfaces of the mounting base 22 are provided with the aforementioned contoured groove 221. Specifically, the upper surface of the mounting base 22 has a downward-facing support groove 222, and the first cover plate 23 is placed in the support groove 222. With the help of the first cover plate 23, the lower half of the earphone shell is pressed down. It is worth noting that the top part of the earphone shell protrudes from the support groove 222, and the top of the earphone shell is also higher than the height of the mounting base 22 and the first cover plate 23. Preferably, the top surface of the first cover plate 23 is flush with the front surface of the mounting base 22 to stably place the inner support 25. The inner support 25 is stacked on the top surface of the first cover plate 23 and the mounting base 22, and the support portion of the inner support 25 extends to the inner side wall of the earphone shell to support the earphone from the inside and prevent the earphone from deforming during the pressure holding process. The second cover plate 24 is stacked on the front surface of the mounting base 22 and the first cover plate 23 and is connected to both the mounting base 22 and the first cover plate 23.

[0035] Please see Figures 5 to 7 A positioning structure is provided between the mounting base 22 and the second cover plate 24. The positioning structure includes a positioning post 271 and a positioning hole 272, which are arranged in a front-rear direction. Specifically, in this embodiment, the mounting base 22 is provided with a positioning post 271, and the second cover plate 24 is provided with a positioning hole 272. The second cover plate 24 is aligned with the mounting base 22 through the alignment between the positioning hole 272 and the positioning post 271. Specifically, the positioning post 271 is provided on the left and right sides of the front surface of the mounting base 22, and the positioning hole 272 is provided through the left and right sides of the second cover plate 24. Of course, in other embodiments of this embodiment, the mounting base 22 is provided with a positioning hole 272, and the second cover plate 24 is provided with a positioning post 271, which can also achieve the purpose of alignment and positioning, so it is not limited to this.

[0036] Please see Figures 5 to 7 A detachable magnetic attraction structure is also provided between the mounting base 22 and the second cover plate 24. The magnetic attraction structure includes a fifth magnetic attraction structure 281 and a sixth magnetic attraction structure 282. The fifth magnetic attraction structure 281 is located on the front surface of the mounting base 22, and the sixth magnetic attraction structure 282 is located on the rear surface of the second cover plate 24. The front surface of the mounting base 22 has a receiving groove for accommodating the fifth magnetic attraction structure 281, and the rear surface of the second cover plate 24 has a receiving groove for accommodating the sixth magnetic attraction structure 282. The fifth magnetic attraction structure 281 and the sixth magnetic attraction structure 282 are aligned with each other in the front-rear direction.

[0037] Please see Figures 1 to 4The pressing assembly includes a central pressing assembly 31, a left pressing assembly 32, and a right pressing assembly 33. The central pressing assembly 31, left pressing assembly 32, and right pressing assembly 33 are slidably mounted on the front surface of the upright plate 12 and located above the carrier 2. The left pressing assembly 32 and right pressing assembly 33 are respectively located on the left and right sides of the central pressing assembly 31. Specifically, the central pressing assembly 31 has a central pressing rod 311, the left pressing assembly 32 has a left pressing rod 326, and the right pressing assembly 33 has a right pressing rod 331. The central pressing rod 311, left pressing rod 326, and right pressing rod 331 all face the product on the carrier 2. Specifically, in this embodiment, the central pressing rod 311 is arranged vertically, the left pressing rod 326 is tilted counterclockwise with respect to the vertical direction, and the right pressing rod 331 is tilted clockwise with respect to the vertical direction. Understandably, the orientation of the pressure bar is not limited to this.

[0038] Please see Figure 4 The left pressing assembly 32, right pressing assembly 33, and middle pressing assembly 31 are all slidably mounted on the upright plate 12 via the sliding guide assembly 5. Specifically, the sliding guide assembly 5 includes a slide rail 51 and a slide seat 52. One of the slide rail 51 and the slide seat 52 is mounted on the upright plate 12, and the other is mounted on the pressing assembly. For example, the bottom of the left pressing assembly 32 is connected to a slide seat 52, and the front surface of the upright plate 12 is connected to a slide rail 51, allowing the slide seat 52 to slide relative to the slide rail 51. It is understood that the specific arrangement of the sliding guide assembly 5 in the right pressing assembly 33 and the middle pressing assembly 31 is almost identical to that in the left pressing assembly 32, and therefore will not be described in detail here. The slide rail 51 and the slide seat 52 ensure smooth sliding of the pressing assembly and provide guidance, thereby ensuring smooth pressure from the pressure rod.

[0039] Please see Figure 3Since the structures of the left pressing assembly 32, right pressing assembly 33, and middle pressing assembly 31 are basically the same, the left pressing assembly 32 will be described in detail, while the right pressing assembly 33 and middle pressing assembly 31 will not be described in detail. Specifically, the left pressing assembly 32 includes a sleeve block 321 and a connecting block 322. The sleeve block 321 and the connecting block 322 are slidably connected. The sleeve block 321 is driven to move by a driving source inside the acupoint. The movement of the sleeve block 321 causes the connecting block 322 to slide relative to the upright plate 12. The left pressing rod 326 is connected to the connecting block 322, and the movement of the connecting block 322 causes the left pressing rod 326 to move. Similarly, in the right pressing assembly 33, the movement of the sleeve block 321 causes the connecting block 322 to slide relative to the upright plate 12. The right pressing rod 331 is connected to the connecting block 322, and the movement of the connecting block 322 causes the right pressing rod 331 to move. Similarly, in the middle pressing assembly 31, the moving of the sleeve block 321 can drive the sliding of the connecting block 322 relative to the upright plate 12. The middle pressing rod 311 is connected to the connecting block 322, and the movement of the connecting block 322 drives the movement of the middle pressing rod 311.

[0040] Please see Figure 3 , Figure 8 and Figure 10 Preferably, the connecting block 322 is provided with a pressure rod mounting hole 3221 for mounting the left pressure rod 326, and the diameter of the pressure rod mounting hole 3221 is larger than the shaft diameter of the left pressure rod 326. Specifically, in this embodiment, the diameter of the pressure rod mounting hole 3221 is 8.2 mm, and the shaft diameter of the left pressure rod 326 is 8.0 mm. A locking rod 323 is connected to the top of the left pressure rod 326. The locking rod 323 includes a head 3231 and a body 3232. The head 3231 protrudes from the pressure rod mounting hole 3221, and the body 3232 is threadedly connected to the left pressure rod 326. The head 3231 is provided with a locking surface 32311, and the connecting block 322 is provided with a stop surface 3222. When the head 3231 is rotated to loosen it, the locking surface 32311 disengages from the locking engagement with the stop surface 3222. At this time, the body 3232 and the left pressure rod 326 can make fine adjustments in the axial and radial directions of the pressure rod mounting hole 3221. When the head 3231 is rotated to tighten it, the locking surface 32311 locks into the stop surface 3222 to lock the current position of the left pressure rod 326 and the locking rod 323.

[0041] It is understood that the driving assembly 4, which drives the left pressing assembly 32 and the right pressing assembly 33 to slide, is installed inside the external acupoint. The driving assembly 4 includes a driver 41 and a sleeve rod 42. The output end of the driver 41 is connected to the sleeve rod 42. The sleeve block 321 is provided with a slot hole 3211 for the sleeve rod 42 to be inserted. When the pressure holding device 100 is assembled inside the acupoint, the sleeve block 321 moves relative to the sleeve rod 42 and is sleeved on the sleeve rod 42. It is worth noting that, in this embodiment, the driver 41 of the middle pressing assembly can be fixed on the upright plate 12 or installed inside the external acupoint. When the driving assembly 4 is working, the driver 41 drives the sleeve rod 42 to move. Since the sleeve block 321 is sleeved on the sleeve rod 42, the sleeve rod 42 drives the sleeve block 321 to move, thereby driving the connecting block 322 to move, thereby driving the pressure rod to move.

[0042] Please see Figure 8 and Figure 9 Preferably, the left pressing assembly 32 also includes a linear bearing 324 and an elastic column 325. The two ends of the elastic column 325 are connected to the sleeve block 321 and the connecting block 322, respectively. The linear bearing 324 includes a bearing seat 3241 and a movable column 3242. The bearing seat 3241 is embedded within the connecting block 322, and the movable column 3242 is located within the bearing seat 3241 and extends out to connect with the sleeve block 321. The movement of the sleeve block 321 simultaneously drives the elastic column 325 to move, which in turn drives the connecting block 322 to move. When the pressure rod presses against the product, the elastic column 325 simultaneously undergoes elastic deformation, allowing the pressure rod to gently maintain pressure on the product. Simultaneously, the pressure rod moves away slowly from the product, thus ensuring the accuracy and effectiveness of the pressure maintenance and preventing damage to the product.

[0043] Referring to the accompanying drawings, the working principle of the pressure-holding device 100 of the present invention is explained as follows: When the pressure-holding device 100 of the present invention needs to be removed from the external acupoint for offline debugging, a screwdriver is used to remove the connecting piece between the base 1 and the external acupoint. Then, force is applied to overcome the force between the first magnetic attraction structure 13 and the second magnetic attraction structure 201 to disassemble the entire base 1 from the external acupoint. After debugging, when the pressure-holding device 100 of the present invention needs to be reinstalled into the external acupoint, the sleeve block 321 in each pressing component is aligned with the sleeve rod 42 of the driving component 4. At the same time, the first magnetic attraction structure 13 and the second magnetic attraction structure 201 attract each other, and under the force of the first magnetic attraction structure 13 and the second magnetic attraction structure 201, the entire base 1 is attracted to the external acupoint. The driving component 4 is activated, and the driving component 4 moves the sleeve rod 42, thereby moving the sleeve block 321, thereby moving the connecting block 322 and the pressure rod. This causes the pressure rod to press against the earphone half-shell, thus pressing the glued charging pin tightly inside the earphone half-shell.

[0044] Compared with the prior art, the pressure-holding device 100 of the present invention has a base 1, and the pressing component and the carrier 2 are both mounted on the base 1. Therefore, by simply disassembling the base 1, the pressing component and the carrier 2 can be removed from the external acupoint together for convenient offline debugging. The back of the upright plate 12 and the bottom surface of the base 1 each have a first magnetic attraction structure 13 for adsorbing onto the external acupoint. The external acupoint has a second magnetic attraction structure 201 that is mutually attracted with the first magnetic attraction structure 13. The first connecting hole 14 of the base 1 is also detachably connected to the external acupoint through a connector. When the present invention is installed back into the external acupoint, it is only necessary to adsorb the base 1 onto the external acupoint for a temporary fastening purpose. Then, the first connecting hole 14 and the acupoint are connected through the connector to achieve a secondary fastening installation purpose. This makes installation convenient and quick. When disassembling the invention from the external acupoint, simply use a tool to remove the connector, releasing the first layer of fixation between the base 1 and the external acupoint. Then, apply force to the base 1 to overcome the magnetic attraction between the base 1 and the external acupoint, and the entire invention can be removed, ensuring the safety of disassembly. The carrier 2 is detachably mounted on the base 1. During offline debugging, the position of the carrier 2 can be adjusted, and different carriers 2 can be used and their positions adjusted according to different products.

[0045] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
