Description

Technical Field

[0001] This application relates to the technical field of junction boxes, specifically to a damping structure and a leather-covered flip-top junction box containing the same. Background Technology

[0002] In daily office work, electrical outlets are common power supply devices, usually installed on desks to provide power to electrical equipment. Currently, outlets are typically placed directly on the desk, making the surface untidy. These exposed outlets are also prone to liquid ingress and dust accumulation, affecting their performance. Furthermore, they are easily accessible to children, posing a safety hazard.

[0003] Based on the shortcomings of directly exposed sockets, a structure has emerged on the market that uses a junction box that can be embedded in a countertop opening to store the socket. However, the covers of these junction boxes typically lack damping mechanisms, resulting in rapid opening and closing with loud noise, sometimes even abnormal rattles. The flipping mechanism is also prone to damage, leading to a shorter lifespan. Furthermore, the covers of these junction boxes are usually made of anodized or spray-coated aluminum alloy panels, which often result in color differences with the matching panels. In winter, the aluminum alloy surface of the junction box cover is cold to the touch. Moreover, existing junction boxes with this structure are usually made as a single piece, and the aluminum alloy cover is difficult to customize, failing to meet different customer size requirements. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, this application provides a damping structure that allows the wire box cover to open and close slowly without abnormal noise, the flipping mechanism is not easily damaged, and the product has a long service life.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a damping structure, which includes a cover disposed at both ends of a wire box frame, each cover being provided with a gear shaft, the gear shaft being provided with a gear oil groove and an axially extending mounting hole; a large gear is fitted onto the gear shaft, the large gear being connected to the gear shaft through the mounting hole and being able to rotate circumferentially relative to the gear shaft; the large gear is provided with at least one oil inlet, the oil inlet being connected to the gear oil groove, the oil inlet being used for injecting damping oil; a gear damper is also provided on the cover, the gear damper being meshed with the large gear, and the gear damper being fitted and connected to the cover plate on the wire box frame.

[0006] By employing the aforementioned structure, and by setting intermeshing damping structures on the cover plate and the wire box frame, the process of flipping the cover plate will cause the gear damper to mesh with the large gear. This application provides an oil inlet on the large gear for injecting damping oil. The damping oil is injected between the large gear and the gear shaft through the inlet, and then evenly distributed circumferentially along the gear oil groove. Since the damping oil is a high-viscosity, high-density oil, the small gear will drive the large gear to mesh and rotate during the cover plate flipping process. The damping oil acts as a damping agent during this rotation, making the cover plate flipping process smoother and effectively reducing the flipping speed, noise, and abnormal sounds. Moreover, this gear meshing method is less prone to damage and improves service life.

[0007] Furthermore, at least three oil inlets are provided, and the three oil inlets are evenly distributed along the inner diameter of the large gear. With this structure, damping oil can be injected through the three evenly distributed oil inlets, so that the damping oil can be injected from multiple directions and distributed more evenly in the gear oil groove. This ensures that the resistance force is balanced during the rotation of the large gear relative to the gear shaft, and achieves smooth opening and closing of the cover plate.

[0008] Furthermore, the gear oil grooves are provided in several quantities, and these several gear oil grooves are evenly distributed along the circumference of the gear shaft; this structure also allows the damping oil to be more evenly distributed between the large gear and the gear shaft, ensuring the smooth opening and closing of the cover plate.

[0009] Furthermore, a gear cover is provided at the outer end of the axial side of the large gear. The gear cover is connected to the mounting hole on the gear shaft through a connector. With this structure, the gear oil groove and the oil inlet can be sealed by the gear cover, thereby encapsulating the damping oil. This allows for the injection of high-density, viscous damping oil into a small sealed cavity. The meshing and rotation of the large gear and the gear damper can be hindered by the internal damping oil, thus achieving a buffering effect when the cover plate flips.

[0010] Furthermore, pre-embedded nuts are provided at both ends of the wire box frame along its length. The cover is connected to the wire box frame by screwing the pre-embedded nuts with bolts. This structure facilitates the disassembly and assembly of the cover and the wire box frame from the ends along the length. The cover can be assembled separately for the damping structure before being fixed as a whole to the wire box frame, making assembly more convenient.

[0011] Furthermore, a rotating sleeve is provided at the bottom of the cover plate along its length, and the rotating sleeve is engaged with the axle of the gear damper. With this structure, when the cover plate is flipped, the rotational meshing between the large gear and the gear damper is achieved through the action between the rotating sleeve and the gear damper.

[0012] Furthermore, the circumferential direction of the rotating sleeve is provided with a notch, the width of which is not greater than the outer diameter of the gear damper's axle. With this structure, the rotating sleeve can be fitted onto the gear damper's axle by squeezing and deforming at the notch position. Thus, during the opening and closing process of the cover plate relative to the wire box frame, it is driven to mesh with the large gear. Under the damping oil's resistance force, the cover plate's flipping effect is achieved.

[0013] Furthermore, the outer diameter of the axle is irregularly shaped, and the inner diameter of the rotating sleeve is adapted to the outer diameter of the axle. With this structure, when the rotating sleeve is fitted onto the axle, the two can be circumferentially limited and rotate synchronously. Thus, during the flipping process of the cover plate, the gear damper can be driven to rotate. The gear damper is provided with gear teeth, and the corresponding large gear is also provided with gear teeth. The gear teeth on the two components mesh with each other, thereby driving the large gear to rotate. During the rotation of the large gear, due to the resistance of the internal damping oil, the flipping process of the cover plate can be buffered.

[0014] Furthermore, the cover plate includes a support plate and a leather cover plate covering the support plate. The extended area of ​​the support plate is not greater than the extended area of ​​the leather cover plate. This structure allows a leather cover plate to be placed on the support plate. The leather cover plate can be selected in different colors, and the leather surface is warm and soft, so it will not feel cold to the touch in winter. Moreover, the interior of the leather cover plate is made of MDF, which can be cut into any shape, thus making it easier to meet the customer's customization needs. The support plate can enhance the overall strength of the cover plate and improve its service life.

[0015] Furthermore, the support plate has an adhesive overflow groove on the surface that is in contact with the leather cover. The adhesive overflow groove is used to contain the adhesive, and the leather cover is bonded to the support plate through the adhesive in the adhesive overflow groove. With this structure, the leather cover is bonded to the support plate by adhesive, which is simple to operate and the connection is firm.

[0016] Furthermore, the periphery of the leather cover extends from the periphery of the support plate, and a downwardly protruding soft pad is provided on the extended leather cover near the opening of the cover. With this structure, when the cover is closed onto the wire box frame, it makes contact with the wire box frame through the soft pad, thereby reducing noise and achieving soft contact without causing damage to the cover.

[0017] Furthermore, the cover has stepped surfaces on both side walls along its width, and the heights of the stepped surfaces on both sides are not equal. Specifically, the height of the stepped surface on the side with the damping structure is lower than the height of the stepped surface on the opposite side. In this way, when the cover plate flips open relative to the wire box frame, this height difference allows the cover plate to achieve a flip angle of at least a certain degree relative to the wire box frame, providing a large opening angle and sufficient space for convenient assembly and disassembly of the internal inserts. The stepped surface on the other side can form a gap with the cover plate that closes to the wire box frame, which facilitates wire exit. Furthermore, a folding plate can be installed on the upper part of this gap to cover the exiting wires, thereby improving the overall storage effect of the wire box.

[0018] This application also provides a leather flip-top cable box containing the damping structure described above. The cable box with this damping structure can inject high-density viscous damping oil into the small space cavity. In this way, the cover body is connected to a small gear, and the small gear is connected to a set of large gears. The meshing rotation of the two sets of gears will be hindered by the damping oil, thereby achieving a buffering effect in the opening and closing process of the cover. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] As attached Figure 1-9As shown, this is a damping structure according to this application. The damping structure includes caps 2 located at both ends of a wire box frame 1. Each cap 2 is equipped with a gear shaft 3. Each gear shaft 3 has a gear oil groove 301 and an axially extending mounting hole 302. A large gear 4 is fitted onto the gear shaft 301. The large gear 4 is connected to the gear shaft 301 through the mounting hole 302 (specifically, the large gear and the large gear wheel can be axially connected and fixed with screws) and can rotate circumferentially relative to the gear shaft 3. The large gear 4 has at least one oil inlet 401, which communicates with the gear oil groove 301 and is used for injecting damping oil. The cover 2 is also provided with a gear damper 5, which meshes with the large gear 4, and the gear damper 5 is fitted with the cover plate 6 on the wire box frame 1; specifically, a cover 2 is provided at both ends along the length of the wire box frame 1, which can be made of plastic material; threaded holes 7 are provided on the cover 2 and the corresponding side wall of the wire box frame 1, and the cover is assembled with the wire box frame 1 by bolts 8; the cover 2 is also provided with a through hole, and then the gear damper 5 is provided with a wheel axle 501, which passes through the through hole and enters the shell formed by the cover 2 and the wire box frame 1. The two ends of the cover plate 6 along the length of the cover plate are fitted with the wheel axle, and the cover plate 6 is opposite to the wire box frame 1; as shown in the attached figure. Figure 3 and Figure 5 As shown, a socket mounting hole 101 is provided on the bottom wall of the wire box frame 1 for the socket to be plugged in and fixed; the gear shaft, large gear, and gear damper of this application are assembled on the wire box frame 1 and the cover plate 6 to form a complete damping structure. The damping structure is provided with two sets of covers 2 located at both ends of the wire box frame 1 in the length direction, and they are symmetrically arranged so that both ends of the cover plate 6 in the length direction are supported by the damping structure to achieve the balance of opening and closing.

[0032] By employing the aforementioned structure, and by setting intermeshing damping structures on the cover plate and the wire box frame, the process of flipping the cover plate will cause the gear damper to mesh with the large gear. This application provides an oil inlet on the large gear for injecting damping oil. The damping oil is injected between the large gear and the gear shaft through the inlet, and then evenly distributed circumferentially along the gear oil groove. Since the damping oil is a high-viscosity, high-density oil, the small gear will drive the large gear to mesh and rotate during the cover plate flipping process. The damping oil acts as a damping agent during this rotation, making the cover plate flipping process smoother and effectively reducing the flipping speed, noise, and abnormal sounds. Moreover, this gear meshing method is less prone to damage and improves service life.

[0033] As attached Figure 4 and Figure 9As shown, at least three oil inlets 401 are provided in this application, and the three oil inlets 401 are evenly distributed circumferentially along the inner diameter of the large gear 4. Specifically, the length extension direction of the three oil inlets 401 is consistent with the axial extension direction of the large gear 4. With this structure, damping oil (commercially available resistance oil, shock-absorbing oil, high viscosity lubricating oil, damping lubricating grease, high resistance lubricating oil, damping lubricating oil, and anti-vibration oil) can be injected through the three circumferentially evenly distributed oil inlets 401, so that the damping oil can be injected from multiple directions, thereby distributing it more evenly in the gear oil groove 301. This ensures that the resistance force is balanced during the rotation of the large gear 4 relative to the gear shaft 3, and realizes the smooth opening and closing of the cover plate 6.

[0034] As attached Figure 3-4 and Figure 7 As shown, the gear oil groove 301 described in this application is provided in a plurality of manners, and the plurality of gear oil grooves 301 are evenly distributed along the circumference of the gear shaft 3. Specifically, the gear oil groove 301 can be composed of a plurality of small gear teeth evenly distributed on the gear shaft and forming a tooth groove between each other. This structure can also make the damping oil more evenly distributed between the large gear 4 and the gear shaft 3, ensuring the smooth opening and closing of the cover plate 6.

[0035] As attached Figure 1-3 , Figure 7 As shown, the outer end of the axial side of the large gear 4 described in this application is provided with a gear cover 9. The gear cover 9 is connected to the mounting hole 302 on the gear shaft 3 through a connector 10 (specifically, a threaded connection structure such as a connecting screw or bolt). Specifically, the gear cover 9 seals the damping oil between the oil inlet 401 and the gear oil groove 301 through axial sealing to prevent leakage. This seals the damping oil, achieving the effect of injecting high-density, viscous damping oil into a small, enclosed cavity. In this way, when the large gear 4 and the gear damper 5 mesh and rotate, they can be jointly damped by the internal damping oil, thereby achieving the buffering effect of the cover plate 6 flipping.

[0036] As attached Figure 3 As shown, the wire box frame 1 described in this application has pre-embedded nuts at both ends along its length. The cover 2 is connected to the wire box frame 1 by screwing the pre-embedded nuts with bolts 8. Specifically, the pre-embedded nuts extend axially along the length of the wire box frame 1. A through hole is provided on the cover 2 for the bolt to pass through. The bolt passes through the through hole and is screwed to the pre-embedded nuts, fixing the cover 2 to the end face of the wire box frame 1. This structure facilitates the disassembly and assembly of the cover 2 and the wire box frame 1 from the ends along the length. The cover can be assembled separately for the damping structure before being fixed as a whole to the wire box frame 1, making assembly more convenient.

[0037] As attached Figure 1 , Figure 3-5 As shown, the bottom of the cover plate 6 described in this application is provided with a rotating sleeve 601 along its length direction. The rotating sleeve 601 is fitted and connected to the axle 501 of the gear damper 5. Specifically, the rotating sleeve 601 is a sleeve structure with a length equal to that of the cover plate 6, located near one edge of the cover plate 6 in the width direction, specifically near the side where the damping structure is located. With this structure, when the cover plate 6 is flipped, the rotating sleeve 601 and the gear damper 5 interact to drive the gear damper 5 to rotate, thereby realizing the rotational meshing action between the large gear 4 and the gear damper 5.

[0038] As attached Figure 3-5 As shown, the circumferential notch 602 is provided on the rotating sleeve 601 of this application. The width of the notch 602 is not greater than the outer diameter of the axle 501 of the gear damper 5. Specifically, the notch 602 can be the same length as the extension length of the rotating sleeve 601. With this structure, the rotating sleeve 601 can be fitted onto the axle 501 of the gear damper 5 by squeezing and deforming at the position of the notch 602. Thus, during the rotation and opening and closing process of the cover plate 6 relative to the wire box frame 1, it is driven to mesh with the large gear 4. Under the resistance force of the damping oil, the buffering effect of the cover plate 6 flipping is achieved.

[0039] As attached Figure 5-6 As shown, the outer diameter of the axle 501 described in this application has an irregular shape (as shown in the figure, it can be a square structure), and the inner diameter of the corresponding rotating sleeve 601 is adapted to the outer diameter of the axle 501. With this structure, when the rotating sleeve 601 is fitted onto the axle 501, the two can be circumferentially limited to achieve synchronous circumferential rotation, so that the gear damper 5 can be driven to rotate along with the cover plate 6 during the flipping process. The gear damper 5 is provided with gear teeth, and the corresponding large gear 4 is also provided with gear teeth. The gear teeth on the two components mesh with each other, thereby driving the large gear 4 to rotate. During the rotation of the large gear 4, due to the resistance of the internal damping oil, the flipping process of the cover plate 6 can be buffered.

[0040] As attached Figure 1 , Figure 3As shown, the cover plate 6 described in this application includes a support plate 603 and a leather cover plate 604 covering the support plate 603. The extended area of ​​the support plate 603 is not greater than the extended area of ​​the leather cover plate 604. Specifically, the leather cover plate 604 is located above the support plate 603 and completely covers the support plate 603. The support plate 603 can be made of metal, such as an aluminum support plate. This structure allows a leather cover plate to be placed on the support plate. The leather cover plate can be selected in different colors, and the leather surface is warm and soft, so it will not feel cold to the touch in winter. Moreover, the interior of the leather cover plate is made of MDF, which can be cut into any shape, thus making it easier to meet the customer's customization needs. The support plate can enhance the overall strength of the cover plate and improve its service life.

[0041] As attached Figure 4-5 As shown, the support plate 603 of this application has an adhesive overflow groove 605 on the surface that is in contact with the leather cover plate 604. The adhesive overflow groove 605 is used to contain the adhesive, and the leather cover plate 604 is bonded to the support plate by the adhesive located in the adhesive overflow groove 605. Specifically, at least two adhesive overflow grooves 605 can be provided and parallel to each other. They can be composed of V-shaped downward recessed grooves. Such V-shaped grooves can improve the bonding firmness with the leather cover plate 604. With this structure, the leather cover plate is bonded to the support plate by adhesive, which is simple to operate and the connection is firm.

[0042] As an example, the periphery of the leather cover plate 605 described in this application extends from the periphery of the support plate 603, and a downwardly protruding soft pad 10 is provided on the extended leather cover plate 605 near the opening side of the cover plate 6 (located on the opposite side of the rotating sleeve); with this structure, when the cover plate 6 is closed onto the wire box frame 1, the soft pad 10 and the wire box frame 1 make contact with each other, thereby reducing noise and achieving soft contact without causing damage to the cover plate 6.

[0043] As attached Figure 7 As shown, the cover 2 described in this application has stepped surfaces 201 on both side walls along the width direction, and the heights of the stepped surfaces 201 on both sides are not equal. Specifically, the height of the stepped surface 201 on the side with the damping structure is lower than the height of the stepped surface 201 on the opposite side. In this way, when the cover plate 6 is flipped open relative to the wire box frame 1, this height difference allows the cover plate 6 to achieve a flip angle of at least 90 degrees relative to the wire box frame 1. The large opening angle provides sufficient space for the assembly and disassembly of the internal inserts. The stepped surface on the other side can form a gap with the cover plate 6 that is closed with the wire box frame 1. This gap facilitates the exit of wires, and a folding plate can be set on the upper part of the gap to cover the exiting wires, thereby improving the overall storage effect of the wire box.

[0044] As attached Figure 1-3 As shown, this application also provides a leather flip-top cable box containing the damping structure described above. The cable box using this damping structure can inject high-density viscous damping oil into the small space cavity. In this way, the cover body is connected to a small gear, and the small gear is connected to a set of large gears. The meshing rotation of the two sets of gears will be hindered by the damping oil, thereby achieving a buffering effect in the opening and closing process of the cover.

[0045] In this damping structure, damping oil is injected through the oil inlet on the large gear, and then the damping oil is evenly distributed between the large gear and the gear shaft. The damping oil is then sealed by the gear cover, thus encapsulating the damping oil and forming a small sealed cavity. The damping oil injected into this sealed cavity is high-density and viscous. In this way, during the meshing and rotation of the large gear and the gear damper, they can be subjected to the damping force of the internal damping oil, thereby achieving the buffering effect of the cover plate flipping.
