Description

Technical Field

[0001] This invention relates to the field of wall panel technology, specifically to a quick-installation double-sided decorative partition wall panel with noise reduction function. Background Technology

[0002] Prefabricated wall panels are decorative panels prefabricated in factories, unlike the traditional on-site plastering, painting, and wallpapering methods. The panels are manufactured as a whole in the factory and then transported to the construction site. They are directly assembled using slots and interlocking structures, requiring minimal glue and nails. This results in less dust and a simpler process, effectively shortening the construction period. The panels are easy to assemble and disassemble, can be disassembled and recycled for reuse, and are environmentally friendly and durable, making them a mainstream prefabricated building material for interior decoration and partition walls.

[0003] Conventional hollow prefabricated wall panels on the market consist of only a single hollow cavity without multiple layers of dedicated noise reduction structures. Sound waves can easily penetrate the wall, and the cavity is prone to resonance, amplifying noise. This results in poor sound insulation and privacy in residential, hotel, and office partitions, failing to meet users' needs for quiet operation. Furthermore, the wall panels are only equipped with a simple interlocking structure, making them prone to misalignment during assembly. Installation requires repeated adjustments, leading to low overall construction efficiency and high labor costs. Summary of the Invention

[0004] This invention provides a quick-installation double-sided decorative partition wall panel with noise reduction function to solve at least one of the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this invention discloses a quick-installation double-sided decorative partition wall panel with noise reduction function. It includes a wall panel core, decorative panels on both ends of the core, a positioning frame and a limiting frame on one side, a positioning block and a limiting block on the other side, several insertion slots at the upper end, several insertion rods at the lower end, buffer components on the upper and lower sides, and a noise reduction component within the core. This combines a basic assembly structure with a noise reduction structure. The upper and lower wall panels are vertically connected via insertion rods and slots, and horizontally assembled by interlocking the positioning frame, limiting frame, positioning block, and limiting block. Simultaneously, the built-in noise reduction structure improves sound insulation, addressing the problems of cumbersome assembly and insufficient sound insulation in traditional wall panels.

[0006] The noise reduction component includes two symmetrically arranged noise reduction mounting cavities. Sound-absorbing cotton is installed on the side of the noise reduction mounting cavities that are far apart from each other. A perforated plate is installed in the center of the noise reduction mounting cavities. Non-woven fabric layers are installed on the side of the two perforated plates that are close to each other. The non-woven fabric layers and the noise reduction mounting cavities enclose the filling cavity, which is filled with sound-insulating sand. The outer sound-absorbing cotton first absorbs some of the noise, the middle perforated plate disperses the sound waves, and the inner non-woven fabric, together with the sound-insulating sand, forms a high-density sound insulation layer, which consumes sound wave energy layer by layer, significantly improving the sound insulation and noise reduction capabilities of the wall panel.

[0007] There are two positioning frames, which are symmetrically fixed on one side of the inner core of the wall panel, and lateral toothed plates are symmetrically arranged inside the positioning frames; there are two positioning blocks, which are symmetrically fixed on the other side of the inner core of the wall panel, and mating toothed plates are symmetrically arranged on the outer surface of the positioning blocks.

[0008] A limiting frame is fixedly installed in the center of the inner core of the wall panel. A partition is installed inside the limiting frame, and a trapezoidal block is fixedly installed on the partition. An L-shaped plate is symmetrically slidably installed on the trapezoidal block, and several return springs are fixedly installed on the L-shaped plate. The other end of the return spring is fixedly connected to the trapezoidal block. A driving cavity is installed inside the trapezoidal block, and a rotating shaft is rotatably installed inside the driving cavity. The rotating shaft rotates through the partition and is equipped with a driving gear. A driving rack is meshed with the upper and lower sides of the driving gear. A driving rod is fixedly installed on the driving rack and passes through the trapezoidal block and is fixedly connected to the L-shaped plate.

[0009] The rotating shaft is also fixedly equipped with clamping gears and limiting gears. The clamping gears are symmetrically meshed with clamping racks, and clamping rods are fixedly connected to the clamping racks. Clamping plates are fixedly connected to the clamping rods. The partition plates are symmetrically provided with sliding grooves, through which the clamping plates slide. The other end of the clamping plates is fixedly connected with clamping toothed plates. The limiting gears are symmetrically meshed with limiting racks, and limiting rods are fixedly connected to the limiting racks. Limiting plates are fixedly connected to the limiting rods. The partition plates are symmetrically provided with moving grooves, through which the limiting plates slide. The other end of the limiting plates is fixedly connected with limiting toothed plates. When the wall panels are joined and pressed together, the L-shaped plates can be pushed to slide, driving the entire gear and rack set to transmit synchronously. This drives the clamping toothed plates and limiting toothed plates to engage and limit from multiple directions. After the panels are joined, they can be automatically locked without repeated manual adjustments or additional locking fasteners. The assembly alignment is precise, effectively improving the problems of panel misalignment and loosening during assembly.

[0010] A square rod is also provided inside the drive cavity. One end of the square rod is fixedly connected to the rotating shaft, and the other end of the square rod is slidably sleeved with an insertion post. The insertion post slides out a trapezoidal block, and the other end of the insertion post is fixedly connected to an insertion plate. A fixing block is rotatably installed on the insertion post, and an elastic element is fixedly installed on the fixing block. The elastic element is sleeved around the insertion post and is fixedly connected to the inner wall of the drive cavity.

[0011] The limiting block has a trapezoidal groove that mates with an L-shaped plate. Engaging toothed plates are located on both sides of the limiting block, mate with the limiting toothed plates. Positioning toothed plates are located on the top and bottom of the limiting block, mate with the clamping toothed plates. The limiting block also has an annular cavity with a square channel running through its center. This square channel mates with an insertion plate. The insertion plate first penetrates the annular cavity inside the limiting block, rotates, and then locks itself into place with the square channel. Simultaneously, an elastic element continuously pushes it forward, preventing the central locking structure from loosening and retracting. This forms a locking structure with four-sided engagement and a central locking, significantly improving the stability of the wall panel splicing.

[0012] The inner core of the wall panel has symmetrical cavities arranged on the top and bottom. A lifting rod is installed in the cavity. The lifting rod slides into the positioning frame. One end of the lifting rod is fixedly connected to a disc, which cooperates with the positioning block. The other end of the lifting rod is fixedly connected to a wedge block, which slides in connection with the cavity. A lifting block is installed on the wedge block, and a lifting rod is fixedly installed on the lifting block. The lifting rod slides upward and extends out of the cavity.

[0013] The buffer assembly includes two buffer plates, one above the other. A lifting rod is fixedly connected to the lower buffer plate. The lower buffer plate has symmetrically symmetrical grooves, and sliding blocks are slidably installed in the grooves. A connecting rod is hinged to the sliding block, and the other end of the connecting rod is hinged to the upper buffer plate. A buffer spring is fixedly installed in the center of the lower buffer plate and is fixedly connected to the lower surface of the upper buffer plate. Shock-absorbing springs are fixedly installed on the opposite sides of the two sliding blocks and are fixedly connected to the grooves. When the wall panels are assembled, the positioning block presses against the disc, which drives the lifting rod, wedge block, and lifting block to move synchronously, pushing the lifting rod to lift the lower buffer plate. The buffer spring and the shock-absorbing springs on both sides absorb the pressure of the joint and offset the stress generated by vibration and thermal deformation. The entire buffer structure starts synchronously with the wall panel assembly, without the need for separate manual adjustment, making it more practical.

[0014] Two fixed blocks are symmetrically fixed on the upper side of the inner core of the wall panel. A plug-in plate is slidably installed through the fixed blocks. A pop-out plate is fixed at one end of the plug-in plate near the center of the inner core of the wall panel. A pop-out component is fixedly installed on the pop-out plate and is fixedly connected to the fixed blocks. Release blocks are fixed at both ends of the lower surface of the buffer plate on the lower side. The release blocks cooperate with the fixed blocks and the pop-out plate. The fixed blocks are also provided with insertion slots. When the buffer plate is raised, the release blocks move upward synchronously, releasing the constraint on the pop-out plate. The pop-out component, after accumulating force, pushes the pop-out plate outward, causing the plug-in plate to insert into the insertion slot of the adjacent wall panel, completing the secondary insertion limit and further improving the splicing firmness of the wall panels.

[0015] In summary, compared with the prior art, this invention provides a quick-installation double-sided decorative partition wall panel with noise reduction function, which has the following beneficial effects: The wall panel is equipped with noise reduction components, which can not only block sound from penetrating the wall but also avoid cavity resonance amplifying noise, significantly improving the sound insulation effect of partition walls in residences, hotels, and offices, ensuring spatial privacy, and meeting the need for quiet use; The wall panel is equipped with matching positioning frames, limiting frames, positioning blocks, and limiting blocks on both sides, forming a double limiting interlocking structure. Combined with corresponding upper and lower insertion slots and vertical splicing rods, the wall panel will not shift left or right during installation, the splicing gaps are neat and uniform, eliminating the need for multiple adjustments and corrections, simplifying the construction process, speeding up installation, and greatly reducing labor costs.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: Embodiments of the present invention provide a quick-installation double-sided decorative prefabricated wall panel with noise reduction function, such as... Figures 1-11 The wall panel core 1 includes decorative panels 3 on both ends of the wall panel core 1, positioning frames 4 and limiting frames 2 on one side of the wall panel core 1, positioning blocks 9 and limiting blocks 10 on the other side of the wall panel core 1, several insertion slots 7 on the upper end of the wall panel core 1, several insertion rods 8 on the lower end of the wall panel core 1, buffer components 6 on the upper and lower sides of the wall panel core 1, and noise reduction components inside the wall panel core 1.

[0022] The working principle and beneficial effects of the above technical solution are as follows: During the wall panel assembly process, the vertical splicing of the wall panels is completed by vertically inserting the insertion rod 8 at the lower end of the wall panel into the insertion slot 7 at the upper end of the adjacent wall panel; when the adjacent wall panels are spliced ​​horizontally, the positioning frame 4 and the limiting frame 2 on one side of the wall panel can be engaged with the positioning block 9 and the limiting block 10 of the other wall panel to achieve horizontal limiting and fixing. The wall panels are not prone to horizontal displacement, the splicing gaps are neat and uniform, no need for multiple calibrations, simplifying the assembly process, effectively improving construction efficiency, and greatly reducing labor costs. The inner core 1 of the wall panel is equipped with noise reduction components, which effectively block the propagation of sound waves, suppress cavity resonance and amplify noise, and significantly improve the sound insulation performance of the partition wall panel. The buffer components 6 set on the upper and lower sides of the wall panel can reduce the thermal expansion and contraction stress caused by temperature changes, and at the same time buffer the impact load generated by slight vibrations of the building, thus extending the service life of the wall panel. The inner core 1 of the wall panel is prefabricated with decorative panels 3 at both ends to form a double-sided decorative structure. No additional finishing construction is required on both sides of the partition wall, simplifying on-site decoration work.

[0023] Example 2: Based on the above embodiment 1, as follows Figures 1-3 As shown, the noise reduction component includes two symmetrically arranged noise reduction mounting cavities 11. Sound-absorbing cotton 14 is installed on the side of the noise reduction mounting cavities 11 that are far apart from each other. A perforated plate 13 is installed in the center of the noise reduction mounting cavity 11. A non-woven fabric layer 12 is provided on the side of the two perforated plates 13 that are close to each other. The non-woven fabric layer 12 and the noise reduction mounting cavity 11 enclose each other to form a filling cavity, which is filled with sound-insulating sand.

[0024] The beneficial effects of the above technical solution are as follows: the two sets of noise reduction installation cavities 11 arranged symmetrically can absorb some of the external noise with the sound-absorbing cotton 14 on the outside of the wall panel; the perforated plate 13 in the middle can disperse the sound waves and reduce the energy of sound transmission; the non-woven fabric layer 12 is set on the inside of the perforated plate, which can not only prevent the internal sound insulation sand from leaking out, but also form a high-density sound insulation layer with the sound insulation sand.

[0025] The synergistic effect of the multi-layered structure improves the shortcomings of ordinary hollow wall panels, such as poor sound insulation and cavity resonance amplification of noise. By consuming sound wave energy in layers, it effectively blocks noise generated by talking or playing audio and video next door, greatly improving the sound insulation effect of the partition wall panel.

[0026] Example 3: Based on the above embodiments 1-2, as follows Figures 1-2 , Figures 4-9 As shown, there are two positioning frames 4, which are symmetrically fixed on one side of the inner core 1 of the wall panel. Lateral toothed plates 43 are symmetrically arranged inside the positioning frames 4. There are two positioning blocks 9, which are symmetrically fixed on the other side of the inner core 1 of the wall panel. The outer surface of the positioning blocks 9 is symmetrically provided with mating toothed plates.

[0027] Preferably, the limiting frame 2 is fixedly installed at the center of the inner core 1 of the wall panel. A partition 25 is provided inside the limiting frame 2. A trapezoidal block 18 is fixedly installed on the partition 25. An L-shaped plate 21 is symmetrically slidably installed on the trapezoidal block 18. Several return springs 37 are fixedly installed on the L-shaped plate 21. The other end of the return spring 37 is fixedly connected to the trapezoidal block 18. A driving cavity 35 is provided inside the trapezoidal block 18. A rotating shaft 16 is rotatably installed inside the driving cavity 35. The rotating shaft 16 rotates through the partition 25. A driving gear 36 is provided on the rotating shaft 16. A driving rack 20 is meshed with the upper and lower sides of the driving gear 36. A driving rod 24 is fixedly installed on the driving rack 20. The driving rod 24 passes through the trapezoidal block 18 and is fixedly connected to the L-shaped plate 21.

[0028] Preferably, a clamping gear 27 and a limiting gear 28 are fixedly mounted on the rotating shaft 16. A clamping rack 30 is symmetrically meshed on the clamping gear 27. A clamping rod 32 is fixedly connected to the clamping rack 30. A clamping plate 33 is fixedly connected to the clamping rod 32. A sliding groove is symmetrically opened on the partition 25. The clamping plate 33 slides through the sliding groove. A clamping toothed plate 19 is fixedly connected to the other end of the clamping plate 33. A limiting rack 29 is symmetrically meshed on the limiting gear 28. A limiting rod 31 is fixedly connected to the limiting rack 29. A limiting plate 34 is fixedly connected to the limiting rod 31. A moving groove is symmetrically opened on the partition 25. The limiting plate 34 slides through the moving groove. A limiting toothed plate 17 is fixedly connected to the other end of the limiting plate 34.

[0029] The working principle and beneficial effects of the above technical solution are as follows: When splicing two wall panels, the positioning frames 4 symmetrically arranged on the upper and lower sides of one wall panel will interlock with the corresponding positioning blocks 9 on the upper and lower sides of the other wall panel. The initial positioning at the upper and lower parts is completed by the interlocking of the lateral toothed plate 43 inside the positioning frame 4 and the mating toothed plate outside the positioning block 9. At the same time, the limiting block 10 on one side of the wall panel will insert into the limiting frame 2 of another wall panel, squeezing the two L-shaped plates 21, causing the two L-shaped plates 21 to slide inward towards each other. While the L-shaped plates 21 are moving, the driving rod 24 and the driving rack 20 will move inward synchronously. The driving rack 20 will translate and drive the driving gear 36 to rotate. The driving gear 36 will drive the rotating shaft 16 to rotate as a whole. After the rotating shaft 16 rotates, it will synchronously drive the clamping gear 27 and the limiting gear 28 to rotate together. The clamping gear 27 rotates, and through the clamping rack 30 and the clamping rod 32, it drives the clamping tooth plate 19 to move towards each other for engagement and limitation. The limiting gear 28 drives the limiting tooth plate 17 to move towards each other for engagement and limitation through the limiting rack 29 and the limiting rod 31, thereby realizing multi-directional locking and fixing of the limiting block 10.

[0030] Automatic locking can be achieved by the alignment and compression of the limiting block 10 and the limiting frame 2, and the positioning frame 4 and the positioning block 9, without the need for manual adjustment, which greatly simplifies the assembly operation and improves the installation speed. Through the synchronous meshing transmission of the drive gear 36, the clamping gear 27 and the limiting gear 28, multi-point synchronous limiting is achieved, which effectively restricts the movement of the wall panel and makes the wall panel splicing more firm and stable.

[0031] Example 4: Based on the above embodiment 3, such as Figures 4-8 As shown, a square rod 26 is also provided inside the drive cavity 35. One end of the square rod 26 is fixedly connected to the rotating shaft 16, and the other end of the square rod 26 is slidably sleeved with an insertion post 22. The insertion post 22 slidably extends out of a trapezoidal block 18, and the other end of the insertion post 22 is fixedly connected to an insertion plate 23. A fixing block 56 is rotatably installed on the insertion post 22, and an elastic element 57 is fixedly provided on the fixing block 56. The elastic element 57 is sleeved around the insertion post 22 and is fixedly connected to the inner wall of the drive cavity 35.

[0032] Preferably, the limiting block 10 has a trapezoidal groove 39 that cooperates with the L-shaped plate 21; the limiting block 10 has meshing toothed plates 40 on both sides that cooperate with the limiting toothed plates 17; the limiting block 10 has positioning toothed plates on the upper and lower sides that cooperate with the clamping toothed plates 19; the limiting block 10 also has an annular cavity 42 that has a square channel 41 that is connected through the center of the annular cavity 42 and cooperates with the insertion plate 23.

[0033] The working principle and beneficial effects of the above technical solution are as follows: When splicing wall panels, the limiting block 10 of one wall panel is inserted into the limiting frame 2 of the adjacent wall panel. The trapezoidal groove 39 inside the limiting block 10 presses the L-shaped plates 21 on both sides, causing the two L-shaped plates 21 to slide inwards towards each other, synchronously driving the drive rod 24 and drive rack 20 to translate, meshing the drive gear 36 to rotate, thereby driving the rotating shaft 16 to rotate. During the process of inserting the limiting block 10 into the limiting frame 2, the insertion plate 23 will first pass through the square channel 41 in the middle of the limiting block 10 and extend into the annular cavity 42. When the rotating shaft 16 rotates, it will drive the square rod 26 to rotate synchronously. The square rod 26 will drive the insertion post 22 and the insertion plate 23 to rotate together. After rotation, the insertion plate 23 will be misaligned with the square channel 41 and will be limited and stuck by the annular cavity 42, unable to come out of the square channel 41, thus completing the locking. During assembly, the elastic element 57 on the outside of the insertion post 22 is in a charged state. The elastic force of the elastic element 57 keeps the insertion post 22 and the insertion plate 23 in place, ensuring that the insertion plate 23 is stably kept inside the annular cavity 42 and will not loosen or move back. At the same time, the limiting tooth plate 17 and the meshing tooth plates 40 on both sides of the limiting block 10 engage, and the clamping tooth plate 19 and the upper and lower positioning tooth plates of the limiting block 10 fit and lock together, so as to achieve synchronous fixation at multiple points. When the limiting block 10 is inserted into the limiting frame 2, the trapezoidal groove 39 presses the L-shaped plate 21 to lock it in place. No manual operation of the locking components is required, resulting in higher assembly efficiency. The limiting toothed plate 17 and the meshing toothed plate 40, the clamping toothed plate 19 and the positioning toothed plate cooperate with each other, and the central limiting structure formed by the insertion plate 23 further restricts the wall panel from multiple directions, making the wall panel connection more stable.

[0034] Example 5: Based on the above embodiment 4, such as Figures 1-2 , Figures 9-11 As shown, the inner core 1 of the wall panel has symmetrically arranged cavities 44. A lifting rod 15 is arranged in the cavity 44. The lifting rod 15 slides into the positioning frame 4. One end of the lifting rod 15 is fixedly connected to a disc 38, which cooperates with the positioning block 9. The other end of the lifting rod 15 is fixedly connected to a wedge block 58, which slides in connection with the cavity 44. A lifting block 46 is arranged on the wedge block 58, and a lifting rod 45 is fixedly arranged on the lifting block 46. The lifting rod 45 slides upward out of the cavity 44.

[0035] Preferably, the buffer assembly 6 includes two buffer plates 59 arranged vertically. A lifting rod 45 is fixedly connected to the lower buffer plate 59. The lower buffer plate 59 has symmetrically formed grooves 50. A sliding block 55 is slidably arranged in the groove 50. A connecting rod 48 is hinged to the sliding block 55. The other end of the connecting rod 48 is hinged to the upper buffer plate 59. A buffer spring 47 is fixedly arranged in the center of the lower buffer plate 59. The buffer spring 47 is fixedly connected to the lower surface of the upper buffer plate 59. A shock-absorbing spring 54 is fixedly arranged on the side of the two sliding blocks 55 that is far apart from each other. The shock-absorbing spring 54 is fixedly connected to the groove 50.

[0036] The working principle and beneficial effects of the above technical solution are as follows: When two wall panels are assembled and joined, the positioning block 9 of one wall panel is inserted into the positioning frame 4, which will push the disc 38 to move. The disc 38 drives the lifting rod 15 to slide in the cavity 44. The movement of the lifting rod 15 drives the wedge block 58 to slide together. The wedge block 58 squeezes the lifting block 46, so that the lifting block 46 drives the lifting rod 45 to lift upward. When the lifting rod 45 is pushed upward, it will push the lower buffer plate 59 upward. If the buffer plate 59 is against the upper wall panel or roof, the position of the upper buffer plate 59 will be restricted and it will not be able to move upward. The lower buffer plate 59 continues to press upward, the middle buffer spring 47 is compressed, and the connecting rod 48 will rotate, causing the two sliding blocks 55 to slide in opposite directions in the groove 50, compressing the shock-absorbing springs 54 on both sides. If there is no obstruction or limit above, the lifting rod 45 will move the entire buffer mechanism upward. In actual installation scenarios, there are usually upper panels or roof limits above the wall panel. The buffer spring 47 and the shock-absorbing spring 54 absorb the pressure of the wall panel joint by their own elastic deformation, and can also offset the stress generated by wall vibration and thermal expansion and contraction, playing a flexible buffering role.

[0037] When assembling the wall panels, the positioning block 9 presses the disc 38, which drives the lifting rod 15, wedge block 58, and lifting block 46 to work together to automatically activate the buffer structure. No manual adjustment is required, and the buffer is adapted synchronously with the wall panel assembly. The buffer component 6, together with the buffer spring 47 in the middle and the shock-absorbing springs 54 on both sides, forms a double buffer structure. With the sliding cooperation of the connecting rod 48 and the sliding block 55, the force is more evenly distributed and the buffering and shock absorption effect is better.

[0038] Example 6: Based on the above embodiment 5, such as Figures 1-2 , Figures 10-11As shown, two fixed blocks 5 are symmetrically fixed on the upper side of the inner core 1 of the wall panel. A plug-in plate 52 is slidably inserted through the fixed block 5. A pop-out plate 51 is fixedly installed at one end of the plug-in plate 52 near the center of the inner core 1 of the wall panel. A pop-out component is fixedly installed on the pop-out plate 51 and is fixedly connected to the fixed block 5. Release blocks 49 are fixedly installed at both ends of the lower surface of the buffer plate 59 on the lower side. The release blocks 49 cooperate with the fixed block 5 and the pop-out plate 51. An insertion slot 53 is also opened on the fixed block 5.

[0039] The two insertion slots 53 on the left and right are staggered. The left insertion slot 53 is located above the left insertion plate 52, and the right insertion slot 53 is located below the right insertion plate 52. The pop-out part is installed at the bottom.

[0040] The working principle and beneficial effects of the above technical solution are as follows: In the initial state, the release blocks 49 at both ends of the bottom of the buffer plate 59 press against the pop-out plate 51 inside the fixed block 5, restricting the pop-out plate 51 from moving outward. At the same time, the pop-out plate 51 stretches the pop-out piece, causing the pop-out piece to compress and store force.

[0041] When the lower buffer plate 59 moves upward, the buffer plate 59 drives the release blocks 49 at both ends to move upward synchronously. The release blocks 49 release the limiting constraints on the fixed block 5 and the pop-out plate 51. The pop-out piece, which was originally stretched and stored, releases its elasticity and pushes the pop-out plate 51 outward. Simultaneously, it drives the insertion plate 52 to slide outward, allowing the insertion plate 52 to be inserted into the corresponding insertion slot 53 of the adjacent wall panel, thus completing the insertion limiting between the two wall panels.

[0042] The square slots 53 on the left and right sides are staggered and work with the pop-out parts installed at the bottom to complete the elastic pop-out insertion. The telescopic movement is synchronized, and the wall panel insertion alignment is more precise. The movement of the lower buffer plate 59 drives the release block 49 to move. No manual operation is required, which can effectively control the automatic pop-out of the insertion plate 52 and make the overall structure linkage smoother.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
