Description

Technical Field

[0001] The present invention relates to household hardware, and in particular to a mounting device for mounting a cabinet door on a cabinet body. Background Art

[0002] Cabinets are widely used as everyday storage furniture. Cabinet doors generally come in two types: sliding doors that slide horizontally, side-hinged swing doors, and flip-up doors that open upward. Sliding doors require tracks and are more complex. Swing doors are simpler, being connected to the cabinet body via hinges. Flip-up doors are also hinged to the cabinet body, but require hinges as connectors and gas struts to maintain their open position. The installation of the flip-up door requires assembling the hinge first and then the gas strut. Both the hinge and the gas strut need to be fastened to the cabinet body and the cabinet door at both ends with multiple screws. This creates extremely high installation precision requirements, and any slight inappropriateness will affect the smoothness of the cabinet door opening and closing. At the same time, the use of a large number of screws will also damage the structural strength of the cabinet body and the cabinet door. In addition, since there is air pressure inside the gas strut, the air pressure pushes the gas rod outward, thereby transmitting the pressure to the cabinet body and the cabinet door at the connection with the gas strut. This is quite different from the force at the hinge connection on the cabinet body and the cabinet door, which may cause the hinge connection on the cabinet body and the cabinet door to be broken, thereby damaging the furniture. Summary of the Invention

[0003] The object of the present invention is to provide an upward-flip door installation device that meets both hinge and support requirements, so as to reduce the installation accuracy requirements of the upward-flip door, better protect its safety in use and increase its service life.

[0004] The flip-up door installation device described in the present invention includes a fixing frame fixedly installed on the inner wall of one side of the cabinet body, a fixing seat fixedly installed on the cabinet door, a support arm assembly connecting the fixing frame and the fixing seat, and a hinge provided with a hinge base and a hinge cup head hinged to each other. The fixing frame is provided with a one-way rotating shaft rotating along a fixed circumferential direction, and the rotation direction of the one-way rotating shaft is consistent with the opening rotation direction of the cabinet door. The one-way rotating shaft is outer-circuited with a damping core providing a damping effect, and a damping shell is connected to the damping core. A tooth plate is fixedly installed on the damping shell, and the axis of the tooth plate coincides with the axis of the one-way rotating shaft and the damping core, and a plurality of gear teeth are provided at the circumferential edge of the tooth plate. The two ends of the support arm assembly are respectively hinged to the fixing frame and the fixing seat, and the end of the support arm assembly hinged to the fixing frame is provided with teeth meshing with the gear teeth of the tooth plate; the hinge base is fixedly installed on the fixing frame, and the hinged cup head is fixedly installed on the cabinet door.

[0005] Furthermore, the damping core includes an inner core and an outer ring with a damping object provided between them. The inner core is provided with an axial through hole and is fixedly mounted on the one-way rotating shaft. The outer ring is fixedly connected to the damping shell.

[0006] Furthermore, the shape of the axial through hole of the inner core and the shape of the outer edge of the one-way rotating shaft are polygonal.

[0007] Furthermore, the damping shell includes a bottom shell and a shell cover which are detachably connected to each other. A receiving cavity for placing the damping core is provided in the bottom shell, and through holes are opened in the bottom shell and the shell cover along the axial direction of the damping core.

[0008] Furthermore, the support arm assembly includes an upper support arm and a lower support arm hinged to each other at one end, and an upper arm clamp and a lower arm clamp are relatively arranged on the outer walls of the hinged ends of the upper support arm and the lower support arm. The upper arm clamp and the lower arm clamp abut against each other after the upper support arm and the lower support arm rotate relative to each other to a set angle. The other end of the upper support arm is hinged to the fixed seat, and the other end of the lower support arm is hinged to the fixed frame and is provided with teeth that engage with the gear plate teeth.

[0009] Furthermore, a card shaft is installed on the fixed seat, and a card slot is opened at the end of the upper support arm and can be sleeved outside the card shaft. A movable card plate is also installed on the upper support arm through a spring, and the end of the card plate can movably close the open end of the card slot.

[0010] Furthermore, the fixing frame includes a box-shaped bottom box with an open side and a bottom plate installed on the open side of the bottom box. The one-way rotating shaft, damping core, damping shell and tooth plate are all arranged in the bottom box, and a through groove connecting the inside and outside is opened on the bottom box. The end of the support arm assembly with teeth passes through the through groove and is hinged to the bottom box.

[0011] Furthermore, the bottom plate is provided with an axis core, the one-way rotating shaft is sleeved on the axis core, and the axis core and the bottom box are provided with coaxially arranged axis holes, and the connecting piece passes through the axis holes of the bottom box and the axis core to connect the bottom box and the axis core.

[0012] Furthermore, the shaft core includes a cylindrical section and a square head section connected to each other. The cylindrical section is cylindrical, while the radial cross-section of the square head section is polygonal.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] The present invention provides a mounting device for a flip door.

[0025] In an embodiment of the present invention, the flip door installation device includes a fixing frame 1 fixedly installed on the inner wall of one side of the cabinet body, a fixing seat 2 fixedly installed on the cabinet door, a support arm assembly connecting the fixing frame and the fixing seat, and a hinge provided with a hinge base 201 and a hinge cup head 202 that are hinged to each other; the fixing frame is provided with a one-way rotating shaft 3 that rotates along a fixed circumferential direction, and the rotation direction of the one-way rotating shaft is consistent with the opening rotation direction of the cabinet door, the one-way rotating shaft is outer-circumferentially provided with a damping core 4 that provides damping effect, the damping core is connected to a damping shell, and a tooth plate 6 is fixedly installed on the damping shell, the axis of the tooth plate coincides with the axis of the one-way rotating shaft and the damping core, and a plurality of gear teeth 61 are provided at the circumferential edge of the tooth plate, the two ends of the support arm assembly are respectively hinged to the fixing frame and the fixing seat, and the end of the support arm assembly hinged to the fixing frame is provided with teeth that mesh with the gear teeth of the tooth plate; the hinge base is fixedly installed on the fixing frame, and the hinged cup head is fixedly installed on the cabinet door.

[0026] like Figure 1-7As shown, the flip door mounting device is fixedly installed between the cabinet door 102 and the cabinet body 101, allowing the cabinet door and the cabinet body to rotate relative to each other and providing support for the cabinet door after flipping up. When the cabinet door rotates, it simultaneously drives the fixed seat and the hinge cup head to rotate. The relative rotation between the hinge cup head and the hinge base is a prior art and will not be described in detail here. The rotation of the fixed seat will in turn drive the support arm assembly, the tooth plate, the damping shell, and the damping core to move. Because the inner core and outer ring of the damping core are provided with damping glue between each other and are connected to the one-way shaft and the damping shell respectively, when the one-way shaft rotates, the force driving the inner core and outer ring to rotate is less than the damping force brought by the damping glue, so that the inner core and outer ring can rotate relatively fixedly with the damping shell; when the one-way shaft cannot rotate, the inner core of the damping core will also not rotate, while the outer ring can rotate with the damping shell, so that the inner core and outer ring produce relative rotation, and the damping glue between them provides a damping effect. Therefore, when the cabinet door is opening, the direction of rotation of the cabinet door is consistent with the direction of rotation of the one-way shaft, and the cabinet door drives the support arm assembly to open, providing the support force required for the cabinet door to open; at the same time, the rotation of the support arm assembly will drive the tooth plate to rotate through the mutually meshing teeth and gear teeth, and the tooth plate will drive the damping shell, damping core and one-way shaft to rotate. The damping core will not provide damping during this process, so that the cabinet door can be opened easily and smoothly. When the cabinet door is closing, the cabinet door drives the support arm assembly to retract in the opposite direction, and the support arm assembly will drive the tooth plate and damping shell to rotate, but this rotation direction is opposite to the rotation direction of the one-way shaft. The one-way shaft will be fixed to the fixed frame, and the inner core and outer ring of the damping core will produce relative rotation to provide damping, so that the cabinet door can only be closed slowly. In this type of flip door installation device, the fixing frame and the components thereon can provide a damping effect, the support arm assembly provides support for the opening of the cabinet door, and the hinge base of the hinge is installed on the fixing frame, which can integrate the hinge into the component that provides damping, thereby reducing the installation accuracy requirements brought by different hardware and ensuring the smooth opening and closing of the cabinet door; at the same time, it can also eliminate the need for installation between the hinge and the cabinet body, thereby reducing the use of screws and better protecting the structural safety of the cabinet door; in addition, the damping structure on the fixing frame will not cause additional force on the cabinet body and the cabinet door, and can drive the cabinet door to rotate synchronously and smoothly with the hinge, thereby better protecting the furniture and increasing its service life.

[0027] In the described flip-up door installation device, the damping core 4 comprises an inner core and an outer ring, with a damping material (such as damping glue) interposed between them. The inner core has an axial through-hole and is fixedly mounted on the one-way rotating shaft 3. The shape of the inner core's axial through-hole and the outer edge of the one-way rotating shaft 3 can be set to polygonal shapes, such as square or hexagonal. The outer ring is fixedly connected to the damping shell. The damping shell comprises a bottom shell 51 and a shell cover 52 that are detachably connected to each other. The bottom shell has a cavity for accommodating the damping core 4, and the bottom shell and shell cover have through-holes along the axial direction of the damping core. This type of damping core structure is mature and stable, effectively ensuring operational stability. In addition, a number of sealing rings 53 are provided between the bottom shell 51 and the shell cover 52 and the damping core 4 to ensure connection stability and sealing.

[0028] The described upper flip door installation device, the support arm assembly includes an upper support arm 7 and a lower support arm 8 hinged to each other at one end, and an upper arm clamping platform 75 and a lower arm clamping platform 82 are relatively arranged at the outer walls of the hinged ends of the upper support arm and the lower support arm. The upper arm clamping platform and the lower arm clamping platform abut against each other after the upper support arm and the lower support arm rotate relative to each other to a set angle, thereby keeping the upper and lower support arms in a relatively fixed state and providing stable support for the opened cabinet door. The other end of the upper support arm is hinged to the fixed seat 2, and the other end of the lower support arm is hinged to the fixed frame 1 through a limit screw 71 and a limit nut 72 and is provided with teeth 81 that mesh with the gear plate teeth 61. When the cabinet door is opened, the cabinet door drives the upper support arm and the lower support arm to rotate and open relative to each other until the lower support arm drives the tooth plate to rotate to the required angle; and when the cabinet door is closed, the cabinet door drives the upper support arm and the lower support arm to contract in the opposite direction, and causes the lower support arm to drive the damping core through the tooth plate and the damping shell to produce a damping effect. This type of upper flip door installation device can ensure that the cabinet door opens comfortably while being able to close more smoothly. When closing the cabinet door, it is only necessary to release the relative fixation between the upper support arm and the lower support arm, and the cabinet door can be closed under its own weight, which makes its operation more convenient. In addition, a card shaft 21 is installed on the fixed seat 2, and a card slot 73 is provided at the end of the upper support arm 7, which can be sleeved on the outside of the card shaft. A movable card plate 10 is also installed on the upper support arm through a spring 9, and the end of the card plate can movably close the open end of the card slot, so that the card slot of the upper support arm can be easily sleeved on the card shaft to stably connect the upper support arm and the fixed seat; in addition, the upper support arm 7 is hollow and the card plate 10 is arranged in the upper support arm, and a limiting groove 74 is also provided on the upper support arm, and a shift block 20 passing through the limiting groove is provided on the card plate. When dismantling is required, the shift block is shifted to drive the card plate to move back to the card slot, thereby removing the upper support arm from the card shaft. The operation is extremely convenient and quick.

[0029] The described flip door installation device, the fixing frame 1 includes a box-shaped bottom box 11 with an opening on one side and a bottom plate 12 installed on the open side of the bottom box, the one-way rotating shaft 3, the damping core 4, the damping shell and the gear plate 6 are all arranged in the bottom box, and the bottom box is provided with a through slot connecting the inside and the outside. The end of the support arm assembly with teeth passes through the through slot and is hinged to the bottom box. The box-shaped setting protects each component, and the through slot is used to limit the rotation of the support arm assembly, thereby achieving effective stroke control and preventing the teeth and gear teeth from falling off; in addition, the bottom plate 12 is provided with an axis core 14, and the axis core 14 includes cylindrical segments and The square head section and the cylindrical section are cylindrical, and the radial cross-sectional shape of the square head section is a polygon, such as a square, hexagon, etc. At the same time, a square hole 15 is provided on the bottom plate 12, which is consistent with the cross-sectional shape of the square head section of the shaft core. The one-way rotating shaft 3 is mounted on the shaft core, and the shaft core and the bottom box 11 are provided with coaxially arranged shaft holes. The connecting member 16 passes through the shaft holes of the bottom box and the shaft core to connect the bottom box and the shaft core. The connecting member can be a rivet, a screw or other existing connecting parts. The setting of this structure can not only further improve the connection stability between the components, but also improve the stability and accuracy of the rotation of the one-way rotating shaft and the damping core.

[0030] In addition, a fixing plate 17 is provided on the side of the fixing frame 1 facing away from the connection between the fixing frame and the cabinet body. The cross-sectional shape of the fixing plate is trapezoidal. The hinge base 201 is provided with a base hole 203 that matches the cross-sectional shape of the fixing plate. The hinge base is inserted into the base hole and fixedly connected to the fixing plate. This structure of the fixing frame and hinge is simple, facilitating assembly and disassembly between the fixing frame and the cabinet body. It also allows for more accurate and convenient connection of the hinge to the cabinet door, effectively improving the smoothness of the cabinet door opening and closing.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
