Description

Technical Field

[0001] This utility model relates to the field of handle buckle structure technology, and in particular to a zinc alloy handle buckle structure that prevents detachment. Background Technology

[0002] Currently, zinc alloy handles are widely used in furniture and building components such as doors, windows, and cabinets due to their excellent strength, corrosion resistance, and aesthetics. Traditional fixing methods for door, window, and furniture handles mainly fall into two categories: screw locking and spring clip locking.

[0003] Screw-locking structures typically require screws to directly fasten the handle to the pivot or panel. While this method provides a secure connection, it has significant drawbacks: installation often requires aligning multiple screws with the screw holes, making the process cumbersome and inefficient; exposed screw holes affect aesthetics; and over time, the screws may loosen, necessitating regular maintenance and tightening.

[0004] To address these issues, spring-loaded snap-fit ​​installation structures have emerged in the market, typically employing a simple spring pin and slot for fixation. However, this type of structure has significant drawbacks in practical applications: First, the snap-fit ​​usually relies solely on the spring force to maintain the engagement. Under frequent use or significant axial tension, the snap-fit ​​can easily overcome the spring force and disengage from the slot, causing the handle to detach completely, posing a safety hazard and impacting the user experience. Second, when the handle needs replacement or repair, the disassembly process is often extremely difficult, usually requiring specialized tools to pry the snap-fit ​​from the inside, making the operation extremely inconvenient and potentially scratching the surface of the components.

[0005] Therefore, existing handle fixing structures cannot simultaneously achieve ease of installation, connection reliability, and ease of maintenance. There is an urgent need for a new type of anti-detachment buckle structure that can ensure a secure connection while enabling quick assembly and disassembly, and effectively prevent accidental detachment. Utility Model Content

[0006] To overcome the aforementioned drawbacks, this utility model provides a zinc alloy handle buckle structure that prevents detachment.

[0007] The technical implementation scheme of this utility model is as follows: a zinc alloy handle buckle structure for preventing detachment includes a lock body, a panel, a handle, a rotating shaft, a mounting block, a support frame, a first spring, a locking block, and a connecting component. Panels are installed on the front and rear sides of the lock body, and a rotating shaft is rotatably connected through the middle of the lock body. The rotating shaft passes through both the front and rear panels. Mounting blocks are detachably installed at both ends of the rotating shaft. A handle is connected to the right end of each mounting block. A support frame is fixedly connected to the middle position inside the mounting block. Locking blocks are slidably connected to both sides of the support frame. Two first springs are connected between each locking block and the support frame. The outer side of the locking block has a beveled structure, and its outer end passes through the mounting block. A locking groove is opened in the rotating shaft at the corresponding position of each locking block. The locking block is locked into the corresponding locking groove. A connecting component is provided on the support frame.

[0008] Furthermore, the lock body, panel, and handle are all die-cast from zinc alloy.

[0009] Furthermore, the angle between the inclined surface on the outer side of the block and its axial movement direction is 30° to 45°.

[0010] Furthermore, the connecting assembly includes a guide block, a rotating frame, a sleeve, a sliding rod, a rotating block, and a locking assembly. The outer ends of the support frame in the front and rear directions are rotatably connected to the rotating frame. The side of each locking block facing the rotating frame is fixedly connected to the guide block. The left and right ends of the rotating frame are slidably engaged with the guide blocks on the corresponding sides. A sleeve is fixedly connected to the rotating frame. A sliding rod is slidably installed inside the sleeve. A rotating block is fixedly connected to the outer end of the sliding rod. The rotating block is located in the inner cavity of the mounting block. The locking assembly is provided on the rotating block.

[0011] Furthermore, the locking assembly includes a second spring, locking rods, and a locking cover. The second spring is connected between the rotating block and the sleeve. The second spring is sleeved on the outside of the sliding rod. The rotating block facing the sleeve has four locking rods connected in a rectangle. Each pair of locking rods, symmetrically positioned above and below, abuts against the guide blocks on the corresponding sides. A locking cover is installed at the outer end of the mounting block. The locking cover presses against the rotating block, keeping the second spring in a compressed state.

[0012] Furthermore, a sealing ring is provided at the joint between the lock cover and the mounting block.

[0013] The present invention has the following advantages: 1. The front side of the locking block is a flat surface, which forms a large-area flat engagement with the locking groove in the rotating shaft, effectively resisting axial tension. After the locking cover is closed, the locking rod is pressed against the guide block by pushing the rotating block, realizing double mechanical self-locking of the locking block position, which greatly improves the handle's anti-drop capability and the stability of the overall structure under frequent use.

[0014] 2. This structure achieves quick disassembly through a unique rotation unlocking mechanism. Simply open the lock cover, and the rotating block will automatically pop out under the action of the second spring. After rotation, the rotating frame will drive the two side blocks to retract synchronously and disengage from the slot. The operation is simple and greatly facilitates the later replacement or maintenance of the handle. Attached Figure Description

Detailed Implementation

[0020] Example: A zinc alloy handle buckle structure to prevent detachment, such as... Figures 1-4As shown, the lock includes a lock body 1, a panel 2, a handle 3, a pivot 4, a mounting block 5, a support frame 6, a first spring 7, a locking block 8, and a connecting assembly. Panels 2 are mounted on the front and rear sides of the lock body 1. A pivot 4 is rotatably connected through the middle of the lock body 1, passing through both the front and rear panels 2. A latch is located on the left side of the lock body 1. An actuating mechanism is integrated inside the lock body 1, connected to both the pivot 4 and the latch, controlling the extension and retraction of the latch. Mounting blocks 5 are detachably mounted at both ends of the pivot 4. A handle 3 is connected to the right end of each mounting block 5. A support frame 6 is fixedly connected to the middle of the mounting block 5. Locking blocks 8 are slidably connected to the left and right sides of the support frame 6. Two first springs 7 are connected between each locking block 8 and the support frame 6. The outer surface of the locking block 8 has a beveled structure, with its outer end passing through... The mounting block 5 and the rotating shaft 4 are provided with corresponding slots for each locking block 8. The locking block 8 is locked into the corresponding slot to achieve a fixed connection between the mounting block 5 and the rotating shaft 4. The front side of the locking block 8 is flat and can form a stable locking with the slot to prevent the mounting block 5 and the handle 3 from accidentally falling off. The angle between the outer slope of the locking block 8 and its axial movement direction is 30° to 45°. This ensures that the slope can generate a large enough component force when it contacts the end of the rotating shaft 4 during installation to smoothly compress the first spring 7 and achieve smooth insertion. It also provides good self-locking performance after locking to resist the force of reverse disengagement. The support frame 6 is provided with connecting components. The lock body 1, the panel 2 and the handle 3 are all die-cast from zinc alloy. Zinc alloy has good strength, wear resistance and excellent casting performance, and also has good corrosion resistance, which extends the service life of the overall structure.

[0021] like Figures 1-4 As shown, the connecting assembly includes a guide block 9, a rotating frame 10, a sleeve 11, a sliding rod 12, a rotating block 14, and a locking assembly. The outer ends of the support frame 6 in the front and rear directions are rotatably connected to the rotating frame 10. The side of each locking block 8 facing the rotating frame 10 is fixedly connected to the guide block 9. The left and right ends of the rotating frame 10 form a sliding fit with the guide block 9 on the corresponding side. The sleeve 11 is fixedly connected to the rotating frame 10. The sliding rod 12 is slidably installed in the sleeve 11. The outer end of the sliding rod 12 is fixedly connected to the rotating block 14. The rotating block 14 is located in the inner cavity of the mounting block 5. The locking assembly is provided on the rotating block 14.

[0022] like Figures 1-4As shown, the locking assembly includes a second spring 13, locking rods 15, and a locking cover 16. The second spring 13 is connected between the rotating block 14 and the sleeve 11. The second spring 13 is sleeved on the outside of the sliding rod 12. Four locking rods 15 are connected in a rectangular shape on the side of the rotating block 14 facing the sleeve 11. Each pair of upper and lower symmetrical locking rods 15 abut against the guide block 9 on the corresponding side, thereby fixing the position of the guide block 9. A locking cover 16 is installed at the outer port of the mounting block 5. A sealing ring is provided at the joint between the locking cover 16 and the mounting block 5, which can effectively isolate dust and moisture from entering the interior of the mounting block 5, protect the internal components, and prevent functional failure due to rust or dirt jamming. It can adapt to more complex environments. A slot is opened on the locking cover 16, which integrates a hinge mechanism and a pin. The pin is inserted into the mounting block 5. By inserting the locking piece into the slot, the hinge mechanism can be controlled to retract the pin, realizing the opening and closing of the locking cover 16. The locking cover 16 presses the rotating block 14, keeping the second spring 13 in a compressed state.

[0023] This device is installed on the door, with two handles 3 located on the inside and outside of the door respectively. These handles control the opening and closing of the bolt in the lock body 1. The bolt engages with the latch on the door frame to lock and open the door. Rotating the handle 3 rotates the shaft 4, which in turn retracts the bolt through a toggle mechanism, disengaging it from the latch and allowing the door to open. Releasing the handle 3 causes the shaft 4 and handle 3 to automatically reverse and reset via a reset mechanism within the toggle mechanism, allowing the bolt to extend again. To disassemble and replace the handle 3, the lock cover 16 must be opened first to release the pressure on the rotating block 14. The second spring 13 then rebounds, pushing the rotating block 14, sliding rod 12, and latch 15 outwards, disengaging the latch 15 from the guide block 9. Rotating the rotating block 14 then causes the sliding rod 12, sleeve 11, latch 15, and rotating frame 10 to rotate synchronously. The rotating frame 10 drives the guide blocks 9 on both sides to move closer together, causing the latch 8 to retract inwards, compressing the first spring 7. When the latch 8 completely disengages from the shaft 4… After the slot is secured, pull the handle 3 outward to remove the entire mounting block 5 from the rotating shaft 4, thus disassembling the handle 3. After releasing the rotating block 14, the first spring 7 rebounds and pushes the locking block 8 and guide block 9 to reset outward. The cooperation between the guide block 9 and the rotating frame 10 drives the rotating frame 10 and other components to reverse and reset. When reinstalling the handle 3, align the mounting block 5 with the port of the rotating shaft 4 and push it inward. After the inclined surface of the locking block 8 contacts the end of the rotating shaft 4, it is pressed inward. The first spring 7 is compressed. Continue pushing the mounting block 5 until the locking block 8 is aligned with the slot. The first spring 7 rebounds and pushes the locking block 8 into the slot, thus fixing the mounting block 5. Then close the lock cover 16. The lock cover 16 pushes the rotating block 14 inward, causing the sliding rod 12 and the locking rod 15 to move inward synchronously. The locking rod 15 abuts against the guide block 9 again, thus locking the position of the guide block 9 and completing the self-locking of the locking block 8. This structure effectively improves the reliability of the handle 3 connection and the anti-fall-off performance.
