Abstract
Description
Technical Field
[0001] This utility model belongs to the field of door and window hinge technology, and particularly relates to a spring-loaded soft-close hinge. Background Technology
[0002] In existing technologies, door hinge designs have certain flaws, frequently resulting in a rebound phenomenon when closing or opening the door. This rebound not only affects the normal use of the door and reduces its lifespan but also causes inconvenience to users. Specifically, when the door is closed or opened, due to the unreasonable hinge structure, a reverse force is generated when the door is near the fully closed or open position, causing the door to suddenly rebound and fail to complete the closing or opening action smoothly. This unsmooth operating experience not only affects the door's sealing performance but may also pose a safety hazard to users. Utility Model Content
[0003] The purpose of this invention is to provide a spring-loaded hinge, which aims to solve the technical problem that hinges in the prior art tend to bounce back when closing a door.
[0004] To achieve the above objectives, this utility model provides a spring-loaded buffer hinge, comprising a fixed base and a hinge hinged together. The fixed base is mounted on a door body and can rotate relative to the hinge between a closed position and an open position. The direction in which the fixed base rotates relative to the hinge towards the open position is a first rotation direction, and the direction in which the fixed base rotates relative to the hinge towards the closed position is a second rotation direction. A buffer block is provided inside the fixed base, and a compression spring is provided between the buffer block and the fixed base. The compression spring is configured to ensure that the buffer block always abuts against the hinge during the rotation of the fixed base. When the fixed base is in the closed position, the buffer block abuts against the hinge and causes the hinge to tend to rotate along the first rotation direction.
[0005] Optionally, the hinge has a first protrusion and a second protrusion. When the fixed seat is in the closed position, the buffer block abuts against the first protrusion of the hinge and causes the hinge to tend to rotate in the first rotation direction. When the fixed seat is in the open position, the buffer block abuts against the second protrusion of the hinge and causes the hinge to tend to rotate in the second rotation direction.
[0006] Optionally, the hinge connects the fixed seats on two adjacent door bodies, and the two fixed seats rotate synchronously in opposite directions to switch between the open position and the closed position.
[0007] Optionally, there are two hinges, which are mirror images of each other and hinged together at their respective midpoints. One end of each hinge is hinged to a fixed seat on one of the door bodies, and the other end is slidably hinged to a fixed seat on the other door body.
[0008] Optionally, the buffer block has an inclined surface at one end that abuts against the hinge, and during the rotation of the fixed seat, the inclined surface abuts against the first protrusion and the second protrusion in sequence.
[0009] Optionally, the buffer block has two mounting holes, and each mounting hole contains a compression spring.
[0010] Optionally, the fixed base is provided with a guide groove, the buffer block is slidably disposed in the guide groove, the buffer block has a sliding groove, and the guide groove has a protrusion that slides and engages with the sliding groove.
[0011] Optionally, the fixing seat is provided with a screw, the end of the screw is flat, the fixing seat is provided with a threaded hole, the screw is screwed into the threaded hole, and the flat end of the screw can abut against the door body.
[0012] Compared with the prior art, the above-mentioned technical solutions of one or more of the spring buffer hinges provided in this utility model embodiment have at least one of the following technical effects: when the fixed seat and the hinge rotate relative to each other, the door can be opened or closed. When the fixed seat rotates relative to the hinge in a first direction, the door gradually opens; when the fixed seat rotates relative to the hinge in a second direction, the door gradually closes. Furthermore, when the fixed seat is in the closed position, the buffer block abuts against the hinge and causes the hinge to have a tendency to rotate in the first rotation direction, which also causes the buffer block to have a tendency to rotate in the second direction. However, since the door is already in a closed state at this time, the buffer block with the tendency to rotate in the second direction can effectively prevent the rebound after the door is closed.

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.
[0028] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0031] like Figures 1 to 7 As shown, this utility model provides a spring-loaded soft-close hinge, including a fixed base 100 and a hinge 200 that are hinged to each other. The fixed base 100 is installed on the door body and can rotate relative to the hinge 200 between a closed position and an open position. The direction in which the fixed base 100 rotates relative to the hinge 200 towards the open position is a first rotation direction, and the direction in which the fixed base 100 rotates relative to the hinge 200 towards the closed position is a second rotation direction. A soft-close block 300 is provided inside the fixed base 100, and a compression spring 400 is provided between the soft-close block 300 and the fixed base 100. The compression spring 400 is configured to ensure that the soft-close block 300 always abuts against the hinge 200 during the rotation of the fixed base 100. When the fixed base 100 is in the closed position, the soft-close block 300 abuts against the hinge 200 and causes the hinge 200 to tend to rotate along the first rotation direction.
[0032] Understandably, when the fixed base 100 and the hinge 200 rotate relative to each other, the door can be opened or closed. Specifically, when the fixed base 100 rotates relative to the hinge 200 in the first direction, the door gradually opens; when the fixed base 100 rotates relative to the hinge 200 in the second direction, the door gradually closes. Furthermore, when the fixed base 100 is in the closed position, the buffer block 300 abuts against the hinge 200, causing the hinge 200 to tend to rotate in the first rotation direction. This also causes the buffer block 300 to tend to rotate in the second direction. However, since the door is already closed at this time, the buffer block 300, which has the tendency to rotate in the second direction, can effectively prevent the door from rebounding after it has closed completely.
[0033] It should be noted that the fixing seat 100 is embedded in the door body. Figure 1In the middle, for the right fixed seat 100, its counterclockwise rotation direction is the first direction and the counterclockwise rotation direction is the second direction. For the left fixed seat, its clockwise rotation direction is the first direction and the counterclockwise rotation direction is the second direction.
[0034] like Figures 1 to 3 As shown, in one embodiment of this utility model, the hinge 200 has a first protrusion 210 and a second protrusion 220. When the fixed base 100 is in the closed position, the buffer block 300 abuts against the first protrusion 210 of the hinge 200, causing the hinge 200 to tend to rotate in a first rotation direction. When the fixed base 100 is in the open position, the buffer block 300 abuts against the second protrusion 220 of the hinge 200, causing the hinge 200 to tend to rotate in a second rotation direction. Because... Figure 1 The highest point of the buffer block 300 inside the right-side fixed seat 100 is located to the left of the first protrusion 210. Therefore, under the upward pushing force of the compression spring 400, the hinge 200 cooperating with the right-side fixed seat 100 has a tendency to rotate counterclockwise, preventing the door closing action from rebounding. Correspondingly, due to Figure 1 The highest point of the buffer block 300 inside the left fixed seat 100 is located to the right of the first protrusion 210. Therefore, under the upward pushing force of the compression spring 400, the hinge 200 that cooperates with the left fixed seat 100 can have a clockwise rotation tendency.
[0035] like Figures 1 to 3 as well as Figure 7 As shown, in one embodiment of the present invention, the hinge 200 connects the fixed seats 100 on two adjacent door bodies, and the two fixed seats 100 rotate synchronously in opposite directions to switch between the open and closed positions.
[0036] like Figures 1 to 3 as well as Figure 7 As shown, in one embodiment of this utility model, two hinges 200 are provided, which are mirror images of each other and hinged together at their respective midpoints. One end of each hinge 200 is hinged to a fixed seat 100 on one of the door panels, and the other end is slidably hinged to a fixed seat 100 on the other door panel. Specifically, the slidable hinge structure can be that the fixed seat 100 is provided with a sliding groove, and the end of the hinge 200 has a cylindrical slider, which can slide and rotate relative to the sliding groove.
[0037] like Figure 4 As shown, in one embodiment of the present invention, the buffer block 300 has an inclined surface 310 at one end of the hinge 200. During the rotation of the fixed seat 100, the inclined surface 310 abuts against the first protrusion 210 and the second protrusion 220 in sequence.
[0038] like Figure 5As shown, in one embodiment of this utility model, the buffer block 300 is provided with two mounting holes 320, and each mounting hole 320 is provided with a compression spring 400. The two compression springs 400 can provide a relatively balanced pushing force to the buffer block 300 to prevent the buffer block 300 from shifting.
[0039] like Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the fixed base 100 is provided with a guide groove 110, and the buffer block 300 is slidably disposed in the guide groove 110. The buffer block 300 has a sliding groove 330, and the guide groove 110 has a protrusion 120 that slides with the sliding groove 330. The cooperation between the sliding groove 330 and the protrusion 120 can provide guidance during the sliding process of the buffer block 300.
[0040] In one embodiment of this utility model, a screw 500 is provided on the fixing seat 100. The end of the screw 500 is flat. The fixing seat 100 has a threaded hole. The screw 500 is screwed into the threaded hole. The flat end of the screw 500 can abut against the door body. The distance between the fixing seat 100 and the door body can be controlled by adjusting the depth of the screw 500 screwed into the threaded hole. This is used to adjust the position of the fixing seat 100 so that when the fixing seat 100 is embedded in the door body, it can be kept as flush as possible with the surface of the door body.
[0041] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
