Description

Technical Field

[0001] This utility model relates to a connector and connection structure for hinges. Background Technology

[0002] Traditional hinge structures, especially those used in applications requiring automatic springback or limiting (such as hinges for electrical door panels), typically involve fixing the main body to the door during installation, with the connecting lever directly fixed to the appliance body using screws. This installation method has the following problems:

[0003] 1. Inconvenient assembly and disassembly: In order to ensure the connection strength, the traditional structure requires a lot of screws to fix the connecting lever arm and the electrical body, which not only increases the complexity of the installation steps, but also leads to low efficiency in subsequent maintenance or disassembly.

[0004] 2. Complex structure and high cost: Connecting lever arms usually require additional protective covers to hide the connecting parts and ensure the aesthetic appearance of the product. This design not only increases the number of parts, but also makes the overall structure more complex, while increasing production and assembly costs, which is not conducive to the product's market competitiveness.

[0005] In view of the shortcomings of the traditional hinge structure, this utility model proposes a new type of connector and connection structure to solve the problems existing in the prior art. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a connector and connection structure for hinges, effectively solving the issues mentioned in the background art.

[0007] The technical solution adopted in this utility model is:

[0008] A connector for a hinge includes symmetrically arranged rotating pieces and connecting pieces. The connecting pieces are fixed between the bottoms of the two rotating pieces, and a lever arm groove is formed between the two rotating pieces. A snap-fit ​​piece is fixed to the right side of each of the two rotating pieces. The snap-fit ​​piece extends from the rotating piece to the outside of the rotating piece. A through hole is formed at the top of the two rotating pieces, and a rivet is fitted inside the through hole.

[0009] Preferably, a push plate is fixed to the top of each of the two rotating pieces, the push plate extending outward from the rotating piece, and the push plate is used to push the connector out of the door's slot.

[0010] Preferably, the rotating plate, connecting plate, snap-fit ​​plate and push plate are integrally formed to improve structural strength and simplify the production process.

[0011] Meanwhile, this utility model also provides a connection structure, including a hinge body, a connecting arm, a connector, and a door body. The rear end of the connecting arm has a strip-shaped hole, which matches a rivet. The rivet can slide laterally within the strip-shaped hole to accommodate positional adjustments between the connector and the connecting arm. The door body has a connecting arm insertion hole for inserting and positioning the connecting arm. The connecting arm insertion hole matches the connecting arm. The door body has slots on both sides of the connecting arm insertion hole that match the snap-fit ​​piece. The sliding entrance of the slot faces the inside of the door body, facilitating the snap-fit ​​piece to slide into the slot for snap-fit ​​fixation.

[0012] Preferably, the connector can rotate around the rivet as an axis, and the main body is provided with a support platform that matches the connector. When the bottom of the connector rotates to one side of the main body, the support platform supports the connector. When disassembling or assembling the door, the support platform can be used to support the connector to achieve rotational limitation and fixation between the connecting arm and the main body. This makes it easier to insert or remove the connecting arm from the arm socket, making the operation more convenient and easier.

[0013] Preferably, when the snap-fit ​​piece is fully engaged in the slot, there is a gap between the top surface of the push plate and the door body. The gap allows the user to apply force to the push plate, which in turn moves the connector, causing the snap-fit ​​piece to disengage from the slot and facilitating the disassembly of the door body.

[0014] The connector and connection structure for hinges proposed in this utility model address the core pain points of traditional hinges, such as inconvenient assembly and disassembly, complex structure, and high cost. It achieves innovative breakthroughs in three aspects: structural design, assembly logic, and functional adaptation. Specific innovations are as follows:

[0015] I. Connector Structure (Integrated Design + Multifunctional Integration, Simplifying Components and Operation):

[0016] 1. Integrated core structure of "rotating plate-connecting plate-clamping plate": Breaking away from the traditional model of relying on multiple screws for fixing the connecting lever arm, the integrated structure of "lever arm groove + clamping fixation" is formed by symmetrically arranged rotating plates, bottom connecting plates and outer extending clamping plates. On the one hand, the integrated molding process eliminates the assembly steps of multiple parts, significantly improves the overall structural strength, and avoids the problem of easy loosening of traditional split parts; on the other hand, the clamping plate replaces the fixing function of screws, transforming the rigid connection of "multiple screws" into a clamping connection, greatly reducing the number of fasteners and simplifying the assembly process from the source.

[0017] 2. Functional adaptation design of push plate and through hole: An outwardly extending push plate is added to the top of the rotating piece, and when the snap-fit ​​piece is fully inserted into the slot, a gap is reserved between the top surface of the push plate and the door body - this gap provides force space for disassembly operation. Users can directly drive the connecting piece to move by pushing the push plate, so that the snap-fit ​​piece can quickly disengage from the slot, solving the tedious problem of unscrewing screws one by one in the traditional structure disassembly; at the same time, the through hole at the top of the rotating piece cooperates with the rivet to realize the basic fixation of the connecting piece and the connecting arm, and also realize the rotation of the connecting piece;

[0018] II. Connection Structure (Disassembly and Assembly Adaptation + Limiting Support, Optimizing Assembly and Maintenance Experience):

[0019] 1. The slotted hole allows for flexible position adjustment: A slotted hole matching the rivet is opened at the rear end of the connecting arm. The rivet can slide laterally in the slotted hole. When the snap-fit ​​piece slides in the slot, the rivet slides synchronously in the slotted hole, providing space for the sliding of the connector during assembly and disassembly.

[0020] 2. Precise positioning combination of lever arm insertion hole and slot: Lever arm insertion holes matching the connecting lever arm are opened on the door body, realizing quick positioning when the connecting lever arm is inserted and reducing alignment errors during assembly; at the same time, the slots on both sides of the lever arm insertion hole are precisely matched with the snap-fit ​​pieces of the connector, and the sliding entrance of the slot faces the inside of the door body, which makes it easy for the snap-fit ​​pieces to slide in along the sliding entrance and achieve snap-fit ​​fixation without the need for additional tools, thus improving assembly efficiency;

[0021] 3. The support platform provides rotational limitation during assembly and disassembly: A support platform matching the connector is provided on the main body. When the connector rotates around the rivet as the axis to the bottom side near the main body, the support platform provides stable support for the connector. At this time, the relative position of the connecting arm and the main body is limited and fixed. When installing the door, this limitation ensures that the connecting arm is stably aligned with the arm insertion hole, avoiding insertion deviation caused by the shaking of the connecting arm. When disassembling the door, the limitation keeps the connecting arm in a fixed position, making it easy to remove from the arm insertion hole, completely solving the inconvenience of manually supporting the connecting arm during the assembly and disassembly of traditional structures.

[0022] III. Cost and Appearance Optimization (Eliminating the protective cover reduces costs and simplifies the structure):

[0023] Traditional structures require additional protective covers to conceal the connectors, while this utility model uses an integrated design of "clamping piece + push plate" to make the connectors themselves simple in structure and ensure a clean appearance without additional covering. The extension direction of the clamping piece and the push plate fits the assembly gap between the door and the main body, so the connectors are not easily exposed after installation. There is no need to equip them with protective covers, which reduces the number of parts, lowers production and assembly costs, and enhances the product's market competitiveness.

[0024] This invention effectively solves the problems of inconvenient assembly and disassembly, complex structure, and high cost of traditional hinges: by using a snap-fit ​​plate and a slot, a push plate to assist in disassembly, and a support platform for limiting, it significantly reduces the amount of screws used, simplifies the assembly and disassembly steps, reduces the difficulty of operation, and improves assembly and maintenance efficiency; the strip-shaped hole enables the assembly and disassembly of the connector and precise positioning of the lever arm insertion hole, enhancing connection stability; at the same time, the integrated design of the connector eliminates the need for an additional protective cover, reduces the number of parts, simplifies the overall structure, reduces production and assembly costs, and balances aesthetics and product market competitiveness.

[0038] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0039] Example 1

[0040] like Figure 1As shown, a connector for a hinge includes symmetrically arranged rotating pieces 31 and connecting pieces 32. The connecting pieces 32 are fixed between the bottoms of the two rotating pieces 31, and a lever arm groove 33 is formed between the two rotating pieces 31. A snap-fit ​​piece 34 is fixed to the right side of each of the two rotating pieces 31. The snap-fit ​​piece 34 extends from the rotating pieces 31 to the outside of the rotating pieces 31. A through hole 35 is opened at the top of the two rotating pieces 31, and a rivet 36 is matched in the through hole 35.

[0041] Each of the two rotating plates 31 has a push plate 37 fixed to its top, and the push plate 37 extends from the rotating plate 31 to the outside of the rotating plate 31.

[0042] The rotating plate 31, connecting plate 32, snap-fit ​​plate 34 and push plate 37 are integrally formed.

[0043] Example 2

[0044] like Figure 2-7 As shown, a connection structure using the connector in Embodiment 1 includes a hinge body 1, a connecting arm 2, a connector 3, and a door body 4. The rear end of the connecting arm 2 has a strip-shaped hole 21, which matches a rivet 36. The rivet 36 can slide laterally within the strip-shaped hole 21. The door body 4 has a lever insertion hole 41, which matches the connecting arm 2. The door body 4 has slots 42 on both sides of the lever insertion hole 41 that match the snap-fit ​​piece 34. The sliding entrance of the slot 42 faces the inside of the door body 4.

[0045] The connector 3 can rotate around the rivet 36 as an axis. The main body 1 has a support platform 11 that matches the connector 3. When the bottom of the connector 3 rotates to one side of the main body 1, the support platform 11 supports the connector 3. During the assembly and disassembly of the door 4, the support platform 11 can support the connector 3 to achieve rotational limitation and fixation between the connecting arm 2 and the main body 1, thus limiting the rotation of the connecting arm 2. Figure 6 As shown, this makes it easier to connect the lever arm 2 and insert it into the lever arm socket 41, making the operation more convenient and easier.

[0046] When the snap-fit ​​piece 34 is fully engaged in the slot 42, there is a gap between the top surface of the push plate 37 and the door body 4. The gap is designed to allow the user to apply force to the push plate 37. By pushing the push plate 37, the connecting piece 3 is moved, causing the snap-fit ​​piece 34 to disengage from the slot 42, which facilitates the disassembly of the door body 4.

[0047] The working principle of this utility model revolves around the entire process of "installation-fixing-disassembly". Relying on the integrated design of the connectors and the limiting and adapting functions of the connection structure, it achieves convenient operation and stable connection. Specifically, it is divided into three parts: installation stage, fixing stage, and disassembly stage, while also covering the synergistic logic of the core components:

[0048] I. Installation Phase: Precise Positioning and Pre-Limiting

[0049] The core of the installation is to achieve rapid alignment between the connecting arm and the door body through structural adaptation, while pre-fixing is accomplished with the help of a support platform to prevent component wobbling from affecting assembly accuracy. The specific steps are as follows:

[0050] Basic assembly of connector and connecting arm: Pass the rivet of connector through the strip hole at the rear end of connecting arm. At this time, the rivet is not completely locked - which realizes the initial connection between connector and connecting arm, and also retains the lateral sliding space of rivet in strip hole, leaving displacement margin for subsequent snap-fit ​​adjustment.

[0051] Connector rotation and support platform limit: With the rivet as the axis, rotate the connector toward the hinge body until the bottom of the connector is in contact with the support platform on the body. The support platform provides stable support for the connector, so that the relative position of the connecting arm and the body is "locked" to prevent the connecting arm from shaking randomly during installation. At this time, the front end of the connecting arm is exactly aligned with the arm insertion hole on the door, completing the precise alignment before assembly.

[0052] Insertion and mating of the connecting arm and the door: Since the support platform has already limited and fixed the connecting arm, the operator does not need to manually support the connecting arm. The front end of the connecting arm can be directly inserted into the arm insertion hole of the door. The shape and size of the arm insertion hole and the connecting arm are precisely matched, which further ensures the longitudinal positioning accuracy of the connecting arm and the door, laying the foundation for subsequent snap-fit ​​fixing.

[0053] II. Fixing Stage: Snap-fit ​​Locking and Structural Stabilization

[0054] During the fixing stage, the door body and the connecting parts are rigidly fixed by the cooperation of the snap-fit ​​piece and the snap-fit ​​slot, while the connection stability is ensured by relying on the structural characteristics of the components. The specific logic is as follows:

[0055] Lateral movement of the snap-fit ​​piece sliding into the slot: After the connecting arm is inserted into the arm socket, support the main body and rotate the connector so that the snap-fit ​​piece of the connector is aligned with the slot on the door. Then push the snap-fit ​​piece into the slot from the sliding entrance until the snap-fit ​​piece is fully embedded in the slot. At this time, the rivet slides laterally along the strip hole of the connecting arm, providing space for the overall movement of the connector. The outer extension structure of the snap-fit ​​piece matches the shape of the slot, forming an "inverted" fixation, replacing the locking function of the traditional screw, and realizing the quick locking of the door and the connector.

[0056] Multi-structure collaboration ensures stability:

[0057] The connector features an integrated structure of "rotating piece - connecting piece - snap-fit ​​piece": the one-piece molding design avoids the risk of loosening of separate parts, and when the snap-fit ​​piece is under force, it can transfer the force to the entire connector, and then transmit it to the connecting arm through the rivet, and finally distribute it to the hinge body, ensuring uniform force distribution and improving connection strength;

[0058] Auxiliary positioning of lever arm socket: After the connecting lever arm is inserted into the lever arm socket, the lateral and longitudinal offset of the door body and the connecting lever arm is restricted. Together with the fixing of the snap-fit ​​piece, it forms "double positioning" to further prevent the door body from shaking or shifting during use.

[0059] Assisted fastening of rivets: After the snap-fit ​​piece is fully inserted into the slot, the rivet can be slightly locked (no need to overtighten to avoid affecting subsequent disassembly). At this time, the rivet restricts the relative sliding between the connector and the connecting lever arm, but does not hinder the subsequent rotation of the connector around the screw, thus balancing fixation and flexibility.

[0060] III. Disassembly Stage: Applying Force with the Push Plate and Rapid Separation

[0061] During the disassembly phase, the gap design of the push plate and the rotation and reset of the connecting parts enable the locking, unlocking, and separation of components, greatly simplifying the operation process. The specific steps are as follows:

[0062] Push plate force application and locking unlocking: When the locking piece is fully inserted into the slot, there is a gap between the top surface of the push plate and the door body (this gap is the force application space). The operator can directly push the push plate into the inside of the door body. The push plate and the rotating piece are integrally formed. After the push plate is subjected to force, it drives the entire connecting piece to move into the inside of the door body. The rivet simultaneously slides in the opposite direction along the strip hole, thereby driving the locking piece to disengage from the slot and releasing the locking between the door body and the connecting piece.

[0063] Connector rotation and connecting arm removal: After the snap-fit ​​piece disengages from the slot, rotate the bottom of the connector towards one side of the main body with the rivet as the axis, so that the support platform supports the connector. At this time, the connecting arm is fixed to the main body. The operator can easily pull the connecting arm out of the arm insertion hole of the door body, complete the separation of the door body from the hinge structure, and the door body can be quickly removed without removing the screws.

[0064] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
