Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a buffer mechanism and hinge with springs on both sides. Background Technology

[0002] Hinges are commonly used to connect the cabinet body and doors of wardrobes or cabinets, enabling the doors to open and close. As people's pursuit of quality of life and home products continues to increase, they are increasingly inclined towards products that are exquisite and compact.

[0003] For example, the utility model patent with authorization announcement number CN219864588U specifically discloses a hinge structure with bidirectional buffer. According to its disclosure and the accompanying drawings, the damping component consists of a hydraulic damper and a spring connected in series. The structure is simple and compact, easy to install, simplifies the installation process of the hydraulic damper and the spring, and also reduces the installation size of the damper in the width direction, which is conducive to the compact design of the hinge, and the hinge as a whole looks thinner.

[0004] The hydraulic damper in the aforementioned patent can achieve a two-way buffering effect. However, in some application scenarios, when the weight of the door is large, the door closing force provided by the aforementioned hinge is small, resulting in the door not being able to close the cabinet tightly and gaps remaining. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a buffer mechanism and hinge with springs on both sides, which solves the problem that the door closing force provided by the hinge in the existing technology is small.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a buffer mechanism with springs on both sides, comprising: The seat has a first receiving groove and a second receiving groove on both sides of the first receiving groove. The first receiving groove communicates with the second receiving groove on both sides respectively, and a spring is provided in each of the second receiving grooves on both sides. The damper is placed in the first receiving groove, and the piston rod of the damper passes through the inner wall of the first receiving groove and is placed outside the seat body; The transmission component is placed at the junction of the first receiving groove and the second receiving grooves on both sides, and the transmission component is fixedly connected to the cylinder of the damper.

[0007] As a further embodiment, the transmission component includes a first force-receiving part, guide parts fixed on both sides of the first force-receiving part, and second force-receiving parts respectively fixed to one end of the guide parts on both sides. The second force-receiving parts on both sides are respectively placed in the second receiving grooves on both sides. The cylinder of the damper is fixed to the first force-receiving part. One end of the springs on both sides acts on the inner wall of the second receiving grooves on both sides, and the other end of the springs on both sides acts on the second force-receiving parts on both sides.

[0008] As a further embodiment, a guide platform is provided at the rear end of the first receiving groove, and a guide groove is formed between the two guide parts, with the guide platform and the guide groove slidingly engaged.

[0009] As a further embodiment, the buffer mechanism further includes a movable plate and a fixed plate. The movable plate is located between the fixed plate and the base. The movable plate can seal the first receiving groove and the second receiving grooves on both sides. A first eccentric wheel is provided between the movable plate and the fixed plate. The bottom of the first eccentric wheel is riveted to the fixed plate. A first oblong hole is provided on the movable plate to cooperate with the first eccentric wheel, so that the movable plate can move in the vertical direction relative to the fixed plate. A second eccentric wheel is provided between the movable plate and the base. The bottom of the second eccentric wheel is riveted to the movable plate. A second oblong hole is provided on the base to cooperate with the second eccentric wheel, so that the base can move in the front-back direction relative to the movable plate.

[0010] This utility model also discloses a hinge, including the above-mentioned buffer mechanism with springs on both sides, and further including a hinge cup and a hinge arm. One end of the hinge arm is connected and fixed to the seat body, and the other end of the hinge arm is hinged to the hinge cup through a first hinge member and a second hinge member respectively. The piston rod of the damper is hinged to the middle of the second hinge member through a third hinge member, so that the damper can move relative to the seat body in the front-back direction.

[0011] The beneficial effects of this utility model are: when the damper moves in the front-back direction, the forces of the springs on both sides act on the same transmission component, and the forces of the springs on both sides are then applied to the damper through the same transmission component. Compared with the prior art which only has one spring, this solution gives the damper a greater force, thereby enabling the damper to bear a greater closing force. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0016] Example 1 As attached Figure 1-2 As shown, this embodiment provides a buffer mechanism with springs on both sides, including a seat 1, a damper 3, and a transmission component 4.

[0017] As attached Figure 3 As shown, the base 1 has a first receiving groove 11 and second receiving grooves 12 disposed on both sides of the first receiving groove 11. The first receiving groove 11 communicates with the second receiving grooves 12 on both sides, and a spring 2 is provided in each of the second receiving grooves 12 on both sides. Specifically, at least one spring 2 is placed in each of the second receiving grooves 12 on each side. In this embodiment, it is preferable to place only one spring.

[0018] As attached Figure 2 As shown, the damper 3 is placed in the first receiving groove 11, and the piston rod 31 of the damper 3 passes through the inner wall of the first receiving groove 11 and is placed outside the seat 1. Specifically, the springs 2 in the second receiving grooves 12 on both sides are mirror-symmetrical about the damper 3. In this embodiment, the damper 3 is preferably a hydraulic damper 3. The damper 3 plays a buffering role, and the piston rod 31 of the damper 3 is used to bear the closing force on the door a.

[0019] As attached Figure 2As shown, the transmission component 4 is placed at the intersection of the first receiving groove 11 and the two second receiving grooves 12 on both sides, and the transmission component 4 is fixedly connected to the cylinder 32 of the damper 3. Specifically, the cylinder 32 of the damper 3 and the transmission component 4 are connected by riveting or welding. In this embodiment, riveting is used, so that the transmission component 4 and the damper 3 form an integral structure.

[0020] As attached Figure 2 As shown, in the front-back direction, both springs 2 can exert a rearward force on the transmission component 4. When the damper 3 moves in the front-back direction, the forces of both springs 2 act on the same transmission component 4, and the forces of both springs 2 are then applied to the damper 3 through the same transmission component 4. Compared with the prior art where there is only one spring 2, this embodiment provides a greater force to the damper 3, thereby allowing the damper 3 to bear a greater closing force.

[0021] Furthermore, as one embodiment, as shown in the appendix Figure 2-4 As shown, the transmission component 4 includes a first force-receiving part 41, guide parts 42 fixed on both sides of the first force-receiving part 41, and second force-receiving parts 43 respectively fixed to one end of the guide parts 42 on both sides. Specifically, the guide parts 42 on both sides are perpendicular to the first force-receiving part 41, and the second force-receiving parts 43 are perpendicular to the guide parts 42, and the first force-receiving part 41, guide parts 42, and second force-receiving parts 43 are integrally bent. The second force-receiving parts 43 on both sides are respectively placed in the second receiving grooves 12 on both sides. The cylinder 32 of the damper 3 is fixed to the first force-receiving part 41. One end of the springs 2 on both sides acts on the inner wall of the second receiving grooves 12 on both sides, and the other end of the springs 2 on both sides acts on the second force-receiving parts 43 on both sides. The above design can save the internal space of the buffer mechanism, thereby making the buffer mechanism more compact, allowing the transmission component 4 and the damper 3 to have a longer travel in the front-back direction, and further allowing the springs 2 on both sides to have a larger deformation, thus exerting a greater force on the transmission component 4 and the damper 3.

[0022] The above description, as shown in the appendix Figure 2As shown, one end of each spring 2 acts on the inner wall of the second receiving groove 12 on both sides, and the other end of each spring 2 acts on the second force-receiving part 43 on both sides. This corresponds to two implementation schemes: First, one end of each spring 2 abuts against the inner wall of the second receiving groove 12 on both sides, and the other end of each spring 2 abuts against the second force-receiving part 43 on both sides. When the damper 3 drives the transmission member 4 forward, the second force-receiving parts 43 on both sides compress the springs 2 on both sides, thereby generating a rearward elastic force on the damper 3. Second, one end of each spring 2 is fixed to the inner wall of the second receiving groove 12 on both sides and away from the piston rod 31 of the damper 3, and the other end of each spring 2 is fixed to the second force-receiving part 43 on both sides. When the damper 3 drives the transmission member 4 forward, the second force-receiving parts 43 on both sides pull the springs 2 on both sides, thereby generating a rearward pulling force on the damper 3. The first implementation scheme is preferred in this embodiment.

[0023] Furthermore, as attached Figure 3 As shown, the rear end of the first receiving groove 11 is provided with a guide platform 14, and a guide groove 421 is formed between the two guide parts 42. The guide platform 14 and the guide groove 421 are slidably engaged, so that the transmission component 4 can maintain linear movement during the forward and backward movement, ensuring that the force of the springs 2 on both sides remains mirror symmetrical, and the force on the damper 3 is more stable.

[0024] Further details are attached. Figure 2 As shown, the buffer mechanism also includes a movable plate 5 and a fixed plate 6. The movable plate 5 is located between the fixed plate 6 and the base 1. The movable plate 5 can seal the first receiving groove 11 and the two second receiving grooves 12 on both sides, thereby preventing the damper 3, the two springs 2 on both sides and the transmission component 4 from disengaging from the first receiving groove 11 and the second receiving groove 12. In the actual installation process, two symmetrical convex plates can be set on the movable plate 5 in the direction perpendicular to the movable plate 5. The outer surface of the two convex plates is integrally formed with a locking protrusion, and a locking groove is opened on the inner wall of the base 1. By extending the convex plate into the base 1, the locking protrusion is inserted into the locking groove, thereby connecting the movable plate 5 and the base 1 together.

[0025] Further details are attached. Figure 2 As shown, a first eccentric wheel 7 is provided between the movable piece 5 and the fixed piece 6. The bottom of the first eccentric wheel 7 is riveted to the fixed piece 6. The movable piece 5 has a first oblong hole 51 that matches the first eccentric wheel 7, so that the movable piece 5 can move relative to the fixed piece 6 in the vertical direction. When the first eccentric wheel 7 rotates in the first oblong hole 51, it pushes the movable piece 5 to move relative to the fixed piece 6 in the vertical direction, while the fixed piece 6 is fixed to the inner wall of the cabinet b.

[0026] Furthermore, as attached Figure 2As shown, a second eccentric wheel 71 is provided between the movable piece 5 and the base 1. The bottom of the second eccentric wheel 71 is riveted to the movable piece 5. The base 1 has a second oblong hole 13 that matches the second eccentric wheel 71, so that the base 1 can move relative to the movable piece 5 in the front-back direction. When the second eccentric wheel 71 rotates in the second oblong hole 13, it pushes the base 1 to move relative to the movable piece 5 in the front-back direction.

[0027] Example 2 As attached Figure 5-7 As shown, this embodiment provides a hinge, including a buffer mechanism with springs on both sides as described in Embodiment 1 above, and also includes a hinge cup 8 and a hinge arm 9. The hinge cup 8 is fixed to the door body a, and one end of the hinge arm 9 is connected and fixed to the seat body 1, preferably by welding. The other end of the hinge arm 9 is hinged to the hinge cup 8 through a first hinge member 10 and a second hinge member 101, respectively. Specifically, one end of the first hinge member 10 and the second hinge member 101 are hinged to the hinge arm 9 through a pin, and the other end of the first hinge member 10 and the second hinge member 101 are hinged to the hinge cup 8 through a pin. The piston rod 31 of the damper 3 is hinged to the middle of the second hinge member 101 through a third hinge member 102, so that the damper 3 can move relative to the seat body 1 in the front-back direction. Specifically, one end of the third hinge 102 is hinged to the piston rod 31 of the damper 3 via a pin, and the other end of the third hinge 102 is hinged to the middle of the second hinge 101 via a pin, thereby allowing the hinge cup 8 to swing relative to the seat 1, realizing the opening and closing of the door a. When the door a opens, it drives the damper 3 to move forward, thereby causing the transmission component to compress the springs 2 on both sides, generating a rearward force on the damper 3. When the door a closes, under the rearward force, it drives the damper 3 to move backward, closing the door a.

[0028] Based on the above description, the hinge of this embodiment is suitable for door a with a relatively large weight, and can generate a large closing force on door a, thus belonging to heavy-duty hinges. Furthermore, it can achieve a buffering effect when opening and closing door a, thereby realizing bidirectional buffering.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
