Hinge base and hinge assembly

Abstract

This invention relates to the field of furniture hardware accessories technology, and discloses a hinge base and hinge assembly. The hinge base includes a fixed plate and an elastic rod. One side of the fixed plate has a first engaging position, and the elastic rod has a fixed position and a second engaging position. The fixed position is connected to the other side of the fixed plate. When the elastic rod undergoes elastic deformation, the second engaging position can move relative to the first engaging position. During installation, the elastic rod is compressed or pulled to deform, causing the second engaging position to move, providing a sufficiently large engaging space and reducing installation difficulty. After installation, the elastic rod can return to its initial state. Furthermore, the latching component of the hinge assembly allows for quick latching installation, ensuring the latching component is firmly engaged at the first and second engaging positions, resulting in good stability. The quick assembly and disassembly function can be achieved using only a single elastic rod component, reducing production costs and effectively improving the product's market competitiveness.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] Hinge base embodiment 1

[0060] like Figure 1 to Figure 2 As shown, embodiment 1 of the present invention provides a hinge base, including a fixed plate 1 and an elastic rod 2, wherein one side of the fixed plate 1 is provided with a first buckling position 11, and the elastic rod 2 is provided with a fixed position 24 and a second buckling position 21, wherein the fixed position 24 is connected to the other side of the fixed plate 1, and when the elastic rod 2 is elastically deformed, the second buckling position 21 can move relative to the first buckling position 11.

[0061] Based on the hinge base of the above technical features, the first buckling position 11 is set on the fixing plate 1, and one segment of the elastic rod 2 is installed on the fixing plate 1 as the fixing position 24, so that the other segment of the elastic rod 2 is limited to the second buckling position 21, and the elastic force of the elastic rod 2 itself can make the second buckling position 21 move. During the installation process, the elastic rod 2 will be squeezed or pulled to deform, so that the second buckling position 21 will move towards the first buckling position 11 to provide a sufficiently large buckling space and reduce the difficulty of installation. After the installation is completed, the elastic rod 2 can be reset to the initial state. Further, the buckle 3 of the hinge assembly can be quickly buckled and installed, so that the buckle 3 is firmly buckled on the first buckling position 11 and the second buckling position 21, and has good stability. The elastic rod 2 with only a single component can realize its quick disassembly and assembly function, effectively reducing its production cost, and on the basis of reducing its cost, ensure the overall strength and durability of the product, and improve its market competitiveness.

[0062] In this embodiment, the second buckling position 21 is located in the middle of the elastic rod 2, and the fixing position 24 is located at the two ends of the elastic rod 2, that is, the position of the second buckling position 21 is changed by elastically deforming the middle of the elastic rod 2. The side of the fixing plate 1 that is in contact with the cabinet is defined as the back side, and the side of the fixing plate 1 that is close to the buckle 3 is defined as the front side. The elastic rod 2 is hidden and installed on the back side, which will not affect the installation space of other components.

[0063] In this embodiment, the fixing plate 1 is provided with a mounting portion 13, and the fixing position 24 is provided on the mounting portion 13 to restrict or fix the fixing position 24 on the mounting portion 13, and the end of the elastic rod 2 is restricted or fixed on the fixing plate 1 through the mounting portion 13. When the elastic rod 2 is a bar-shaped rod, during the elastic deformation process, its end will be pulled to move, and the mounting portion 13 is used to restrict its end, providing a certain movement space for the end. When the elastic rod 2 is a bent rod or a folded rod, during the elastic deformation process, the deformation of its bent or folded portion can make the second buckling position 21 move, and the end will not be pulled to move, and the mounting portion 13 is used to fix its end, and the installation stability is better.

[0064] Furthermore, the mounting portion 13 includes a first connecting wall 131 and a first top wall 132 connected to the first connecting wall 131, the first connecting wall 131 is connected to the fixing plate 1, and the fixing position 24 is installed between the first top wall 132 and the fixing plate 1. That is, a plate-like structure is punched out from the front to the back, and is defined into the first connecting wall 131 and the first top wall 132 by bending, and the end of the elastic rod 2 is placed between the first top wall 132 and the first fixing plate 1, and the first top wall 132 is pressed toward the first fixing plate 1, so as to limit or fix the end of the elastic member in the fixing plate 1. The assembly process of the elastic rod 2 is simple and convenient, which can ensure high production efficiency.

[0065] In this embodiment, the fixing plate 1 is provided with a first limiting portion 12, and the elastic rod 2 is inserted into the first limiting portion 12, so that the elastic rod 2 is elastically deformed in the first limiting portion 12. The elastic rod 2 is limited on the fixing plate 1 by the first limiting portion 12, so that the elastic rod 2 can only move toward or away from the first buckling position 11, and the elastic rod 2 is prevented from being separated from the fixing plate 1 during the elastic deformation process, wherein the elastic rod 2 is a rod-shaped structure made of elastic material, and the elastic deformation of the elastic rod 2 refers to bending deformation, and the rigidity is relatively large. After the bending deformation, it can be restored to the initial rod-shaped structure, and its cross-section is circular or elliptical, and it can be placed in any direction, and it can also be made of a rod-shaped spring with relatively large rigidity, and the present invention is not limited here.

[0066] Furthermore, the first limiting portion 12 includes a second connecting wall 121 and a second top wall 122 connected to the second connecting wall 121, the second connecting wall 121 is connected to the fixed plate 1, and the elastic rod 2 is inserted between the second top wall 122 and the fixed plate 1, that is, a plate-like structure is stamped out from the front to the back, and is defined into the second connecting wall 121 and the second top wall 122 by bending. When the elastic rod 2 can be placed in the gap between the second top wall 122 and the fixed plate 1, the elastic rod 2 is restricted to move within the gap.

[0067] In this embodiment, the fixing plate 1 is provided with a buckle interface 16, and the elastic rod 2 is straddled on the buckle interface 16, so that the second buckle position 21 is located on the buckle interface 16, and the buckle interface 16 provides a larger buckle space for the second buckle position 21, and can ensure that the fixing plate 1 as a whole has a larger fitting area with the cabinet. Among them, the installation portion 13 and the first limiting portion 12 are arranged on both sides of the buckle interface 16.

[0068] Furthermore, a protrusion 17 extending toward the buckle interface 16 is provided in the middle position of the fixing plate 1, and two buckle grooves 161 are formed between the protrusion 17 and the two sides of the buckle interface 16. The two second buckle positions 21 are correspondingly located on the buckle grooves 161, and the buckle grooves 161 play a guiding role, facilitating the fastener 3 to be quickly buckled into the second buckle position 21, thereby further improving the convenience of installation.

[0069] Among them, the protrusion 17 is an arc shape that is recessed toward the back side of the fixed plate 1. It can be understood that the middle position of the fixed plate 1 is an arc shape that is recessed toward the back side of the fixed plate 1, which is used to avoid the damper and other components of the hinge assembly, so that the overall space occupied after installation is small and the structure is more compact.

[0070] In this embodiment, the fixing plate 1 is provided with a mounting groove 14, the mounting groove 14 is located on both sides of the buckle interface 16 and communicates with the buckle interface 16, and the elastic rod 2 is located in the mounting groove 14. The entire elastic member can be directly placed in the mounting groove 14, which plays a more stable installation role, wherein the mounting portion 13 is provided at the end of the mounting groove 14, and the mounting portion 13 plays a mounting role on the end of the elastic rod 2, ensuring that the elastic can only be elastically deformed in the mounting groove 14.

[0071] In this embodiment, the fixing plate 1 is provided with a movable groove 15, and the mounting groove 14 is connected to the buckle interface 16 through the movable groove 15. The middle position of the elastic rod 2 that needs to be elastically deformed is located in the movable groove 15, ensuring that the second buckle position 21 has a sufficiently large moving space. The width of the movable groove 15 is greater than the width of the mounting groove 14, that is, the width of the movable groove 15 is greater than the width of the mounting groove 14, and the width of the movable groove 15 gradually increases in the direction close to the second buckle position 21, so that the movable groove 15 is roughly triangular or elliptical in shape to adapt to the bending deformation of the middle position of the elastic rod 2, that is, the elastic rod 2 passes through the mounting groove 14-active groove 15-buckle interface 16-active groove 15-mounting groove 14 in sequence along the length direction, and the buckle interface 16 can be manufactured by stamping or cutting. Among them, the first limiting portion 12 is arranged on the movable groove 15 to ensure that the elastic rod 2 will not be separated from the movable groove 15 during the elastic deformation process.

[0072] The fixing plate 1 is formed by a stamping process to form the mounting groove 14, the movable groove 15, the first limiting portion 12 and the mounting portion 13, which are integrally formed, have low manufacturing costs and higher stability. The mounting groove 14 and the movable groove 15 are stamped from the back to the front, so that the elastic rod 2 is hidden and installed on the back without affecting the installation space of other components. The first limiting portion 12 and the mounting portion 13 are both stamped from the front to the back to form a plate-like structure.

[0073] Hinge base embodiment 2

[0074] The main difference between this embodiment and the first embodiment is the structure of the elastic rod 2, and the structures of other parts are not described in detail here.

[0075] like Figure 3 and Figure 4 As shown, the end of the elastic rod 2 is provided with a deformable first bending position 22, and the first bending position 22 is a bending angle or an arc angle of any angle. During the elastic deformation process, the middle part of the elastic rod 2 will pull the first bending position 22 to deform, thereby realizing the movement of the second buckling position 21, wherein the end of the elastic rod 2 can be fixed on the mounting portion 13, which also makes the installation stability of the elastic rod 2 better.

[0076] Hinge base embodiment 3

[0077] The main difference between this embodiment and the second embodiment is the structure of the elastic rod 2, and the structures of other parts are not described in detail here.

[0078] like Figure 5 and Figure 6As shown, the middle position of the elastic rod 2 is provided with a second bending position 23 for changing the position of the second buckling position 21, and the second bending position 23 enables the middle position of the elastic rod 2 to be bent toward the front side of the fixing plate 1, so that the second buckling position 21 can be closer to the front side of the fixing plate 1, which is convenient for buckling and installation with the buckle 3.

[0079] Hinge base embodiment 4

[0080] The main difference between this embodiment and the first embodiment is the type of the elastic rod 2 and its installation method, and the structures of other parts are not described here in detail.

The second buckling position 21 is located at the two ends of the elastic rod 2, so that the second buckling position 21 is located on the buckling groove 161. That is, by deforming the two ends of the elastic rod 2, the position of the second buckling position 21 is changed.

[0082] The elastic rod 2 is integrally arranged across the buckle interface 16, and the fixing position 24 can be fixed on the mounting portion 13, or the two ends of the elastic rod 2 can be abutted and limited by the two sides of the buckle interface 16 to prevent the elastic rod 2 from detaching in the left and right directions.

The second bending positions 23 enable the two ends of the elastic rod 2 to be bent toward the front of the fixing plate 1. The second buckling position 21 can be closer to the front of the fixing plate 1 and match the shape of the protrusion 17, so as to avoid the damper and other components of the hinge assembly and facilitate buckling installation with the snap-on member 3.

[0105] like Figures 15 to 20 As shown, the present invention also provides a hinge assembly, including a latch 3 and a hinge base as in any of the above embodiments, wherein one side of the latch 3 is provided with an elastic latching structure latched with the first latching position 11, and the other side of the latch 3 is provided with a hook portion 31 latched with the second latching position 21.

[0106] The hinge assembly based on the above technical features uses the hook portion 31 of the snap member 3 to hook the second snap-fit ​​position 21, so that the second snap-fit ​​position 21 undergoes elastic deformation and then moves, and the elastic snap-fit ​​structure is snapped on the first snap-fit ​​position 11 from the other direction, and has a bidirectional elastic effect, that is, no matter whether the second snap-fit ​​position 21 is snapped first, or the first snap-fit ​​position 11 is snapped first, or both are snapped at the same time, the snap member 3 can be quickly installed and firmly snapped on the first snap-fit ​​position 11 and the second snap-fit ​​position 21, and has multiple installation methods and high flexibility. When disassembling, it is only necessary to detach the elastic snap-fit ​​structure from the first snap-fit ​​position 11, and then the hook portion 31 can be taken out from the second snap-fit ​​position 21 to complete the disassembly work. The hinge assembly can be quickly disassembled and assembled, with low production costs, and can effectively improve the market competitiveness of the product.

[0107] In this embodiment, the elastic fastening structure includes a clamping member 4 and a spring 5. The clamping member 4 is rotatably arranged on the buckle 3 through a rotating shaft 6. One end of the spring 5 is connected to the clamping member 4, and the other end of the spring 5 is connected to the buckle 3. The clamping member 4 is provided with a clamping portion 41 which is fastened to the first fastening position 11. The clamping portion 41 is located on a side close to the rotating shaft 6, and the spring 5 is located on the other side away from the rotating shaft 6. Under the action of the spring 5, the other side of the clamping member 4 can be lifted up so that it can rotate along the rotating shaft 6, that is, the clamping portion 41 is pressed toward the inner side of the buckle 3 to achieve a clamped fastening on the first fastening position 11.

[0108] Furthermore, the clamping member 4 is provided with a guide portion 42, and the guide portion 42 is provided with an arc guide surface, and the guide portion 42 is located above the clamping portion 41. When the first buckling position 11 is located at the guide portion 42, the arc guide surface is squeezed by pressing, so that the clamping portion 41 is tilted outward, so that the first buckling position 11 quickly enters the bottom of the clamping portion 41, thereby realizing the buckling of the first buckling position 11.

[0109] In this embodiment, combined with Fig.17As shown, the bottom of the pressing member 4 is provided with a third limiting portion 43 for limiting the rotation range of the pressing member 4, and the third limiting portion 43 abuts against the buckle 3. When the spring 5 pushes the pressing member 4 to rotate to a certain extent, the third limiting portion 43 abuts against the inner wall surface of the buckle 3, so that the spring 5 is installed between the pressing member 4 and the buckle 3, wherein the pressing member 4 and the buckle 3 are both provided with a cone for installing the spring 5 to prevent the spring 5 from being disengaged. The other side of the pressing member 4 is also provided with a handle portion 44 extending outward, and the spring 5 is compressed by pressing the handle portion 44, thereby achieving the first buckling position 11 where the pressing portion 41 is disengaged.

[0110] In this embodiment, the buckle 3 includes a bottom plate 32 and side plates 33. The side plates 33 are arranged on both sides of the bottom plate 32 so that the bottom plate 32 and the side plates 33 on both sides form a U-shaped groove. The U-shaped groove can be used to install components such as dampers. The hooks 31 are arranged on the side plates 33 on both sides and cooperate with the two second buckling positions 21. The buckle 3 can be formed by bending a sheet metal part, with the middle position defined as the bottom plate 32 and the two sides defined as the side plates 33. Fig. 20 As shown, the buckle 3 is connected to the hinge cup 7 via a rotating assembly. The rotating assembly is a prior art, and its specific structure and working principle are not described in detail here.

[0111] Furthermore, the two side panels 33 are each provided with a first positioning portion 34, and the fixed plate 1 is provided with a positioning groove 18 that cooperates with the first positioning portion 34. During the buckling process, the first positioning portion 34 needs to be inserted into the positioning groove 18 for buckling installation to avoid buckling in the opposite direction, and the buckle 3 can be aligned with the first buckling position 11 and the second buckling position 21.

[0112] Furthermore, the fixing plate 1 is provided with a second positioning portion 19 extending toward the U-shaped groove. During the buckling process, the second positioning portion 19 is in contact with the inner wall surface of the side plate 33 to further guide and limit the position, thereby preventing the buckle 3 from moving left and right in the buckled state.

[0113] In this embodiment, the side panel 33 is provided with a protrusion 35 which is tightly pressed against the fixing plate 1, that is, when in the buckled state, the protrusion 35 is tightly pressed against the fixing plate 1. On the one hand, the fastener 3 can be prevented from loosening. On the other hand, when disassembling, the protrusion 35 plays a role in pushing open the fixing plate 1, so that the clamping portion 41 can quickly disengage from the first buckling position 11, thereby achieving a quick disassembly effect.

[0114] In this embodiment, combined with Fig.15As shown, the hook portion 31 is provided with an arc groove 311 protruding outward inside. When in the buckled state, the arc groove 311 clamps the second buckling position 21 to prevent the second buckling position 21 from moving back and forth inside the hook portion 31. The outer side of the hook portion 31 is provided with a guide slope 312. When the second buckling position 21 abuts against the guide slope 312, the second buckling position 21 can be guided to quickly enter the arc groove 311.

[0115] The hinge assembly of this embodiment has three buckle installation methods: (1) Fig.17 As shown, the hook portion 31 of the fastener 3 is hooked onto the second fastening position 21 of the elastic rod 2, and the first fastening position 11 is located on the guide portion 42. By pressing the fastener 3 and squeezing the guide portion 42, the first fastening position 11 quickly enters the lower part of the pressing portion 41, thereby realizing the fastening installation of the fastener 3 and the base. (2) Fig.18 As shown, the first fastening position 11 is placed under the pressing portion 41, and by pressing the fastener 3, under the guidance of the guide slope 312, the second fastening position 21 is pushed to move in the direction of the first fastening position 11, so that the second fastening position 21 quickly enters the hook portion 31, thereby realizing the fastening installation of the fastener 3 and the base. (3) Fig.19 As shown, the first snap-fitting position 11 is placed on the guide portion 42, and the second snap-fitting position 21 is placed on the guide slope 312 of the hook portion 31, and the fastener 3 is pressed. At the same time, the first snap-fitting position 11 squeezes the guide portion 42 and the hook portion 31 pushes the second snap-fitting position 21 to move, so that the first snap-fitting position 11 quickly enters under the clamping portion 41 and the second snap-fitting position 21 quickly enters the hook portion 31, thereby realizing the quick snap-fit ​​installation of the fastener 3 and the base.

[0116] The hinge assembly of this embodiment is disassembled as follows: the handle portion 44 is pressed to compress the spring 5 and drive the clamping portion 41 to rotate, so that the clamping portion 41 is quickly disengaged from the first buckling position 11 under the pushing action of the protrusion 35, and then the elastic rod 2 is removed from the hook portion 31, thereby realizing the rapid disassembly of the fastener 3 and the base.

[0117] In summary, the above-mentioned embodiments of the present invention provide a hinge base and hinge assembly having the following advantages: (1) the elastic deformation of the elastic rod 2 itself is utilized to realize that the second buckling position 21 can be moved relative to the first buckling position 11, thereby realizing the rapid installation of the snap member 3 and the base; (2) the installation groove 14, the movable groove 15, the first limiting portion 12 and the installation portion 13 are formed by stamping, and are integrated into one, with low cost and good stability; (3) the middle portion of the fixed plate 1 can be set to be an arc shape that is concave toward the back to avoid the damper of the hinge assembly, which occupies a small space after installation and has a more compact structure; (4) the elastic buckling structure and the elastic rod 2 form a bidirectional elastic effect, which greatly improves the efficiency of installation and has high flexibility; (5) the overall structure is simple and compact, with low production cost, and can effectively improve its market competitiveness while ensuring the overall strength and durability of the product.

[0118] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
