Description

Technical Field

[0001] This utility model relates to hinges, specifically to a hinge elastic limiting buffer fastener assembly, and a hinge having the assembly. Background Technology

[0002] Hinges are commonly used as connectors for opening and closing structures, enabling the hinge to open and close around an axis. Currently, there is a type of hinge where the front and rear ends of the inner and outer hinge plates are connected to the hinge cup and hinge arm, respectively, to form the hinge body. A buffer component is installed inside the hinge arm. This type of hinge provides a cushioning effect when the hinge body is closed. However, during the opening process, especially when the user opens it with considerable force, the lack of a buffer structure between the inner and outer hinge plates and the hinge cup makes it susceptible to strong impacts. This can cause significant impact forces on the hinge components themselves or between the hinge and the mounting point, reducing the structural stability of these components and the mounting point. Furthermore, during the unfolding process of the hinge arm and hinge cup relative to the inner and outer hinge plates, there is a certain amount of play at the end of the unfolding stroke. Therefore, when this type of hinge is installed in cabinets or cabinet doors, if the impact of this play is not considered and two adjacent cabinet doors are placed too close together, opening both doors simultaneously can cause them to collide, easily leading to damage. Summary of the Invention

[0003] The purpose of this utility model is to provide a hinge elastic limiting buffer fastener assembly, which can be installed in the hinge to provide buffer force as a buffer assembly during the opening process of the hinge cup and hinge arm. It can also eliminate difficult-to-control opening misalignment through the cooperation of the fastening recess and the limiting protrusion, and more accurately control the full opening range of the hinge.

[0004] To achieve the above objectives, the present invention employs the following technical means:

[0005] A hinge elastic limiting buffer fastener assembly includes a hinge arm, a hinge cup, an inner hinge piece, an outer hinge piece, a front outer hinge piece hinge shaft, a front inner hinge piece hinge shaft, a rear outer hinge piece hinge shaft, and a rear inner hinge piece hinge shaft, and is further provided with an elastic limiting member and a fastener.

[0006] One end of the elastic limiting member is an elastic free end, and the other end is a fixed part. The fastening recess is provided between the elastic free end and the fixed part, and the fixed part is fixedly installed in the inner cavity of the hinge cup.

[0007] The fastener is fixedly installed on the outer hinge plate, and the surface of the fastener is provided with a limiting protrusion that matches the fastening recess;

[0008] During the unfolding process of the hinge cup relative to the hinge arm, the outer hinge plate drives the fastening piece to rotate and causes the limiting protrusion to press the elastic free end to undergo elastic deformation and slide into the fastening recess. When the hinge cup is fully unfolded relative to the hinge arm, the limiting protrusion slides into the fastening recess.

[0009] During the closing process of the hinge cup relative to the hinge arm, the outer hinge plate drives the fastening part to rotate and causes the limiting protrusion to slide out of the fastening recess and press the elastic free end to undergo elastic deformation. Before the hinge cup is fully closed relative to the hinge arm, the limiting protrusion slides out of the fastening recess and the elastic free end returns to its original position.

[0010] In some embodiments, the inner cavity of the hinge cup is provided with a fixing part mounting position, and the outer hinge plate is provided with a fastener mounting position.

[0011] In some embodiments, the mounting position of the fixing part includes a fixing hole provided on the rear wall of the inner cavity of the hinge cup and a fastening wall provided on the bottom wall of the inner cavity of the hinge cup. The fixing protrusion at the rear end of the fixing part cooperates with the fixing hole, and the front wall and the rear wall of the fixing part abut against and / or fasten to the fastening wall and the rear wall of the inner cavity of the hinge cup, respectively.

[0012] In some embodiments, the mounting position of the fixing part is further provided with a limiting pin, which is located in the angle region between the rear section of the fixing part and the fastening recess.

[0013] In some embodiments, the fixing part is a U-shaped spring sheet, which is composed of a front abutment piece, a lower bottom piece, a middle folded piece, and an upper elastic piece. The fixing protrusion is disposed on the middle folded piece of the U-shaped spring sheet. The rear edges of the lower bottom piece and the upper elastic piece abut against the rear wall of the inner cavity of the hinge cup. The limiting pin is disposed in the angled area between the upper elastic piece and the rear section of the fastening recess. The front abutment piece abuts against and / or fastens to the fastening wall.

[0014] In some embodiments, the fastener mounting position is a locking hole provided on both sides of the outer hinge plate, and the fastener has locking protrusions on both sides that cooperate with the locking hole.

[0015] In some embodiments, the fastener mounting position is the enclosing gap between the front outer hinge hinge shaft, the top wall of the outer hinge, and the two side walls of the outer hinge; the fastener has an arc-shaped base plate on its lower side and an upper limit portion facing upward at its front end, the limiting protrusion is disposed on the surface of the arc-shaped base plate, the arc-shaped base plate is disposed within the enclosing gap between the front outer hinge hinge shaft, the top wall of the outer hinge, and the two side walls of the outer hinge, the upper limit portion abuts against the leading edge of the outer hinge, and the top wall of the fastener abuts against the top wall of the outer hinge.

[0016] In some embodiments, the elastic limiting member is in a rolled-up or folded shape.

[0017] In some embodiments, the contact surface between the elastic free end and the limiting protrusion is at least partially arcuate.

[0018] By installing the hinge elastic limiting buffer fastener assembly of this utility model onto the hinge, during the unfolding process of the hinge cup relative to the hinge arm, the limiting protrusion of the fastener presses down on the elastic free end to cause elastic deformation. The elastic deformation provides a buffering force for the hinge unfolding. In addition, the cooperation between the limiting protrusion and the fastening recess restricts the opening range of the hinge and the hinge arm, avoiding the influence of the hinge's unfolding misalignment. This allows the hinge to provide an unfolding buffering effect for adjacent cabinet doors that are installed close together, and also prevents the cabinet doors from colliding with each other.

[0019] This utility model has at least the following advantages:

[0020] This utility model has a simple structure and can be adapted to existing hinges. It only requires simple structural modifications to the hinge cup and outer hinge plate of the existing hinge to adapt to the installation of fasteners and elastic limiting parts, and the modification cost of existing hinge production equipment is low.

[0021] By rationally designing different structures for elastic limiting components and fasteners, a high degree of structural compactness, ease of installation, and high durability can be achieved.

[0022] By pressing the elastic free end with the limiting protrusion, the elastic free end deforms and provides a buffering effect, which can serve as a buffer component to provide buffering force during the opening process of the hinge cup and hinge arm. By pairing and fastening the fastener and the elastic limiting part, and by cooperating with the fastening recess and the limiting protrusion, the difficult-to-control opening misalignment can be eliminated, and the full opening range of the hinge can be controlled more accurately. Moreover, based on the structure of the elastic limiting part and the fastener, it is possible to effectively pre-set the final opening angle of the hinge cup and hinge arm by installing fasteners and elastic limiting parts with different relative positions and relative angles of the limiting protrusion and the fastening recess, which can be adapted to the installation of adjacent cabinet doors with different spacing.

[0033] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

They are only for the convenience of describing the utility model and do not require the utility model to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0035] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0036] Taking the buffer hinge, first developed by the utility model inventor and published under the number CN221220136U, as an example, this embodiment describes the application of the elastic limiting buffer fastener assembly of the hinge in the buffer hinge, specifically:

[0037] The buffer hinge provided in this embodiment has an inner hinge plate front hinge hole 215 and an outer hinge plate front hinge hole 225 connected to the hinge cup 11 via a U-shaped pin 13. The two pin portions of the U-shaped pin 13 serve as the front outer hinge plate hinge shaft 131 and the front inner hinge plate hinge shaft 132. The inner hinge plate rear hinge hole 214 and the outer hinge plate rear hinge hole 224 are respectively connected to the hinge arm 12 via a lower fixing pin 72 and an upper fixing pin 71, allowing the hinge cup 11 and the hinge arm 12 to open and close relative to each other, guided by the inner hinge plate 21 and the outer hinge plate 22. A buffer assembly 3 and a spring 14 are installed on the hinge arm 12. An elastic limiting buffer fastener assembly of this embodiment is installed between the hinge cup 11 and the outer hinge plate 22. Specifically:

[0038] An elastic limiting member 4, which is in the shape of a coil, is installed in the inner cavity of the hinge cup 11. The end of the elastic limiting member 4 near the outer hinge piece 22 is the elastic free end 41, and the end near the inner cavity of the hinge cup 11 is the fixed part 43. The fastening recess 422 is provided between the elastic free end 41 and the fixed part 43. The front section 421 and the rear section 423 of the fastening recess form an angle with each other, and the front section 421 of the fastening recess serves as the elastic free end 41.

[0039] The fixing part 43 of the elastic limiting member 4 is fixedly installed in the inner cavity of the hinge cup 11. Specifically, it can be irreversibly installed and fixed or detachably installed and fixed by one or more of the following methods: locking, screwing, riveting, fastening, and adhesive fixing.

[0040] The fastener 5 is fixedly installed on the outer hinge plate 22. The surface of the fastener 5 is provided with a limiting protrusion 51 that cooperates with the fastening recess 422. Specifically, in this embodiment, the fastener 5 can also be irreversibly installed and fixed to the outer hinge plate 22, or detachably installed and fixed. For example, the two can be irreversibly installed and fixed by adhesive bonding, or the fastener 5 and the outer hinge plate 22 can be detachably installed and fixed by providing a fastener mounting position. Figure 1 Generally, a pair of locking holes 226 are provided on both sides of the outer hinge plate 22, and a pair of locking protrusions 53 provided on both sides of the fastener 5 that cooperate with the locking holes 226 are provided. When the locking holes 226 and the locking protrusions 53 are engaged and fixed, the fastener 5 and the outer hinge plate 22 can be installed and fixed separately.

[0041] Based on the above structure, during the unfolding process of the hinge cup 11 relative to the hinge arm 12, the outer hinge piece 22 drives the fastening piece 5 to rotate and causes the limiting protrusion 51 to press the elastic free end 41 to undergo elastic deformation and slide towards the fastening recess 422. At this time, due to the elastic deformation process of the elastic free end 41, a certain buffering effect is provided for the unfolding of the hinge cup 11 and the hinge arm 12. When the hinge cup 11 is fully unfolded relative to the hinge arm 12, the limiting protrusion 51 slides into the fastening recess 422. Therefore, under the fastening action of the fastening recess 422 on the limiting protrusion 51, the angle between the hinge cup 11 and the hinge can be locked, so that the cabinet and cabinet door with this hinge installed can form a fixed unfolding angle after unfolding, thereby eliminating the unfolding play at the end of the unfolding stroke. In addition, by setting the position of the limiting protrusion 51 in a reasonable way, a reasonable opening angle can be formed between the cabinet door and the cabinet body, so that when two adjacent cabinet doors are opened, they will not be over-opened due to the opening play of the hinge, thus avoiding collision between the two adjacent cabinet doors.

[0042] Furthermore, during the closing process of the hinge cup 11 relative to the hinge arm 12, the outer hinge plate 22 drives the fastening member 5 to rotate and causes the limiting protrusion 51 to slide out of the fastening recess 422 and press the elastic free end 41 to undergo elastic deformation. This provides a slight damping sensation when the user closes the cabinet door, preventing accidental closing. Before the hinge cup 11 is fully closed relative to the hinge arm 12, the limiting protrusion 51 slides out of the fastening recess 422 and the elastic free end 41 returns to its original position. The buffer assembly 3 installed in conjunction with the hinge arm 12 provides a damping closing effect for the entire cabinet door closing process.

[0043] As an effective embodiment, when the fixing part 43 of the elastic limiting member 4 is irreversibly fixed to the inner cavity of the hinge cup 11, or detachably fixed, it is possible to adopt... Figure 8 In a typical solution, the fixing plate 40 of the elastic limiting member 4 is locked to the bottom of the inner cavity of the hinge cup 11 by screws 44, and the rear side wall of the inner cavity of the hinge cup 11 abuts against the rear wall of the fixing plate 40, so that the elastic limiting member 4 and the inner cavity of the hinge cup 11 are detachably fixed. Correspondingly, this type of installation only requires the addition of automated drilling stations for the screw holes of the hinge cup 11, screw locking stations, installation stations for the elastic limiting member 4 and fasteners 5 to the existing hinge production equipment, resulting in low equipment modification costs; or adopting a method such as Figure 9 Generally, by setting a mounting position for the fixing part 43, namely, a fixing hole 111 on the rear wall of the inner cavity of the hinge cup 11 and a fastening wall 112 on the bottom wall of the inner cavity of the hinge cup 11, the fixing protrusion 401 at the rear end of the fixing plate 40 mates with the fixing hole 111, the front wall and rear wall of the fixing part 43 abut against the fastening wall 112 and the rear wall of the inner cavity of the hinge cup 11 respectively, and the upper end of the fastening wall 112 bends and presses against the front end of the fixing plate 40, so that the fixing plate 40 is irreversibly installed in the mounting position of the fixing part 43 in the inner cavity of the hinge cup 11; or by adopting a method such as Figure 6 Generally, by setting the fastening wall 112 of the mounting position of the fixing part 43 to be in an upright state, and setting a large contact surface between the front wall of the fixing part 43 and the fastening wall 112 to provide sufficient friction, so that the front wall of the fixing part 43 and the rear wall of the fixing part 43 abut against the upright fastening wall 112 and the rear wall of the inner cavity of the hinge cup 11 respectively, a stable installation and fixing effect can be achieved. At the same time, a relatively convenient detachable effect can be achieved between the elastic limiting member 4 and the inner cavity of the hinge cup 11. Correspondingly, this type of installation method only requires the addition of an automated punching station for the fixing hole 111 on the rear wall of the inner cavity of the hinge cup 11, an installation station for the elastic limiting member 4, an installation station for the fastening member 5, and a punching and bending station for the fastening wall 112 to the existing hinge production equipment. It also has a low equipment modification cost and reduces the use of fasteners such as screws and rivets, and the accessories avoid the possibility of misinstallation of fasteners.

[0044] As an effective embodiment, based on the locking hole 226 provided in the outer hinge plate 22 and the matching locking protrusion 53 provided in the fastener 5, this embodiment can also further optimize the structure of the fastener 5, and in conjunction with the structural gaps of the hinge structure, enable the fastener 5 to have higher structural compactness and installation stability. Specifically, the enclosing gap between the front outer hinge plate hinge shaft 131, the top wall of the outer hinge plate 22, and the side walls of the outer hinge plate 22 serves as the fastener mounting position; the lower side of the fastener 5 is provided with an arc-shaped base plate 52, and the front end is provided with an upward-facing upper protrusion 54 as an upper limit part, the limiting protrusion 51 is provided on the surface of the arc-shaped base plate 52, and the arc-shaped base plate 52 is provided within the enclosing gap between the front outer hinge plate hinge shaft 131, the top wall of the outer hinge plate 22, and the side walls of the outer hinge plate 22, the hinge... The production equipment adds a fastener installation station, where the upper protrusion 54 abuts against the leading edge of the outer hinge piece 22, and the top wall of the fastener 5 abuts against the top wall of the outer hinge piece 22. This allows for pre-limiting the fastener 5 during installation onto the outer hinge piece 22, facilitating accurate fixing of the locking hole 226 and the locking protrusion 53. This prevents over-installation of the fastener 5 and outer hinge piece 22 at the fastener installation station, which could cause the locking hole 226 and locking protrusion 53 to slip off. Furthermore, it can also... Figure 8 As shown, the upper limit position is set as an upper limit hook 55. Through this structure, the edge can be fastened and fixed, which can further improve the pre-limiting effect of the combination process between the fastener 5 and the outer hinge piece 22.

[0045] By using the enclosing gap as the mounting position for the fastener, during the unfolding of the hinge cup 11 relative to the hinge arm 12, the leading edge of the outer hinge piece 22 can press against the upper protrusion 54 that abuts against it and drive the fastener 5, thereby causing the arc-shaped substrate 52 to rotate in the forward direction along the hinge axis 131 of the front outer hinge piece; while during the closing of the hinge cup 11 relative to the hinge arm 12, the top wall of the outer hinge piece 22 can press against the top wall of the fastener 5 that abuts against it and drive the fastener 5, thereby causing the arc-shaped substrate 52 to rotate in the reverse direction along the hinge axis 131 of the front outer hinge piece. Based on this configuration, the size of the locking hole 226 and the matching locking protrusion 53 can be reduced. This structure assists the fastener mounting position structure of the locking hole 226-locking protrusion 53, which reduces the necessary size of the locking hole 226-locking protrusion 53. This allows the locking hole 226-locking protrusion 53 to serve as an auxiliary fixation rather than the main force-bearing structure that drives the fastener 5 to rotate due to the outer hinge plate 22. This provides a more convenient and separable installation and fixation effect for the fastener 5 and the outer hinge plate 22. It also reduces the structural wear that may be caused by the frequent opening and closing of the hinge due to the simple use of the locking hole 226-locking protrusion 53 structure, thereby further improving the service life of the combined structure between the outer hinge plate 22 and the fastener 5.

[0046] As an effective embodiment, the front section 421 and the rear section 423 of the fastening recess can be set to form an angle of about 75°-90° between each other, and the distance between the flared ends of the fastening recess 422 is more than 2mm, so as to provide a space for the limiting protrusion 51 with sufficient thickness.

[0047] As an effective embodiment, the mounting position of the fixing part 43 is also provided with a limiting pin 6, which is located in the angled area between the fixing part 43 and the rear section 423 of the fastening recess. By providing the limiting pin 6, it can act as a component to prevent the rear section 423 of the fastening recess from deforming towards the fixing part 43, thereby avoiding excessive deformation of the rear section 423 of the fastening recess towards the fixing part 43 caused by the limiting protrusion 51 pressing the elastic free end 41 during the relative opening and closing of the hinge cup 11 and the hinge arm 12. This allows the elastic free end 41 to act as the main elastic deformation part when the limiting protrusion 51 presses the elastic free end 41, thereby providing a stronger elastic damping effect and improving the overall lifespan of the elastic limiting member 4.

[0048] As an effective embodiment, to reduce wear, high-strength plastic can be used as the material for the fastener 5 and the elastic limiting member 4 to extend the service life of the structure and ensure smooth and reliable operation during daily use. Alternatively, the contact surface between the elastic free end 41 and the limiting protrusion 51 can be at least partially arc-shaped. In this embodiment, by setting the elastic free end 41 to form an arc surface and both ends of the limiting protrusion 51 to be protruding arc surfaces, the contact surface between the hinge cup 11 and the hinge arm 12 is... During the opening and closing process, when the fastener 5 rotates in the forward direction, causing the lower arc surface of the limiting protrusion 51 to press against the elastic free end 41 and deform elastically, or when the fastener 5 rotates in the reverse direction, causing the upper arc surface of the limiting protrusion 51 to press against the elastic free end 41 and deform elastically, a relatively smooth elastic deformation effect can be achieved, and the wear between the elastic free end 41 and the limiting protrusion 51 caused by the hinge of the opening and closing hinge cup 11 can be effectively reduced. Of course, the surface of the limiting protrusion 51 can also be set to be arc-shaped, which can also achieve a relatively smooth sliding effect.

[0049] As an effective embodiment, such as Figure 6 As shown, the fixing part 43 is a U-shaped spring sheet, which consists of a front abutment piece 431, a lower base piece 432, a middle folded piece 433, and an upper elastic piece 434. The fixing protrusion 401 is located at the middle folded piece 433 of the U-shaped spring sheet. The rear edges of the lower base piece 432 and the upper elastic piece 434 abut against the rear wall of the inner cavity of the hinge cup 11. The limiting pin 6 is located in the angled area between the upper elastic piece 434 and the rear section 423 of the fastening recess. The front abutment piece 431 abuts against the fastening wall 112. With this arrangement, when the elastic free end 41 is momentarily subjected to a large force and moves backward, the rear section of the elastic free end 41 pulls the front abutment piece 431, causing the U-shaped spring sheet to move upward as a whole. Combined with the pressing of the upper elastic piece 434 by the limiting pin 6, the elastic deformation of the U-shaped spring sheet can reduce the large instantaneous force, thereby giving the elastic limiting member 4 a stronger impact resistance.
