Description

Technical Field

[0001] This utility model relates to a panel lock, specifically a rotary impact panel lock. Background Technology

[0002] Currently, the latch-type panel locks used in the industry generally consist of a handle assembly, a panel assembly, a torsion spring, a pivot, and a latch, as disclosed in Chinese patent literature, application number 20202041052.1, authorized announcement date 2021.01.08, utility model name "Waterproof Panel Lock". However, the industry currently uses such locks in many vibration scenarios. Their internal components are generally connected by multiple parts; if one part fails, the function malfunctions and cannot be repaired, causing the locked cabinet door to lose its pre-tightening or become impossible to open. Therefore, further improvements are needed to the unlocking device and its connection structure of existing similar products to meet the aforementioned requirements for shockproof and anti-opening operation. Simultaneously, existing latch-type panel locks rarely use a rotational impact method for locking and unlocking. A rotational impact panel lock needs to be designed to meet the aforementioned shockproof and anti-accidental opening operation requirements, as well as to achieve locking and unlocking through a rotational impact method. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a rotary impact panel lock that addresses the technical problems of inconvenient production and assembly, high production costs, and a limited range of impact locking methods in existing similar products, particularly the lack of a rotary impact mechanism structure design and a shockproof and accidental opening prevention operation structure design. This objective is achieved through the following technical solution.

[0004] A rotary impact panel lock has a panel fixed to a door panel. The top of the panel has a handle slot, and one side of the handle within the handle slot is hinged via a pivot and a handle torsion spring. A key structural design feature is a handle lever on the outer diameter of the curved side of the handle hinge within the handle slot. The handle lever is aligned with a drive shaft extending from the bottom of the panel. The drive shaft is located at one end corner of the rotating bracket of a rotating component at the bottom of the panel, and the panel at the point where the drive shaft extends has an arc-shaped hole. One end of the drive shaft of the rotating component is fixed to the bottom of the panel by a locating pin, and a rotary torsion spring is located at the locating pin for the rotating component to swing. When the handle is rotated, the rotating component rotates, causing the handle lever to abut against the drive shaft within the arc-shaped hole in the panel. Simultaneously, the rotating component causes the lock head to rotate and disengage from the lock hole at the fixed bracket on the door frame. When the handle is released, the handle and the rotating component return to their original positions via the handle torsion spring and the rotary torsion spring, respectively. This allows the handle to rotate to a certain angle, which in turn drives the rotating component to rotate via the transmission shaft, thus separating the rotating component from the fixed base bracket. The rotating component replaces the latch component in existing similar products, enabling locking and unlocking.

[0005] When the handle rotates the handle lever up to 15 degrees or less, there is no free travel between the handle lever and the drive shaft of the rotating component. After the angle exceeds 15 degrees, the handle lever drives the drive shaft. After the angle exceeds 45 degrees, the handle detaches from the drive shaft. The drive shaft forms a 15-degree angle along the arc-shaped hole of the panel with the positioning pin as the center. The above and below angles correspond, but are not limited to, the range of the above and below angles, based on the condition that the handle vibration will not trigger the drive shaft, and the rotating component will rotate and detach from the locking hole of the fixed bracket.

[0006] The locking mechanism of the rotating component consists of a guide wheel and a guide wheel mounting groove with an arc-shaped protrusion at the lower panel corresponding to the arc-shaped hole on one side of the rotating bracket above the drive shaft. The guide wheel and guide wheel mounting groove engage with or disengage from the locking hole of the fixed base bracket as the rotating bracket rotates. The above is a specific structural embodiment of using the guide wheel and guide wheel mounting groove of the rotating component as the locking mechanism to engage or disengage from the locking hole of the fixed base bracket; a bolt-type locking tongue structure can also be used.

[0007] The rotating component has a symmetrical rotating bracket at the other end of its drive shaft with a through sliding pin. The rotating bracket at the through-hole of the sliding pin has a sliding hole, and one end of the sliding pin is inserted and fixed to the bottom of the panel. The sliding hole of the rotating bracket forms a 45-degree angle with the positioning pin as the center. The sliding hole and the corresponding sliding pin of the rotating bracket further improve the stability of the rotating component during rotation.

[0008] The rotating bracket of the rotating assembly is a sheet metal structure formed by bending the sliding hole and the two sides of the guide wheel. The two sides of the sheet metal are connected and fixed by sliding pins and positioning pins, and a connecting pin is provided between the two sides of the sheet metal at the guide wheel. The above is a specific structural embodiment of the rotating bracket of the rotating assembly made of sheet metal.

[0009] The rotating component has a curved limiting side plate on one side of the drive shaft at the rotating bracket. When the locking head of the rotating component is inserted into the locking hole of the fixed base bracket, the limiting side plate of the rotating bracket abuts against the fixed base bracket to limit the movement. This structure facilitates the unlocking and locking of the rotating component when it is fully closed.

[0010] The handle is equipped with a lock cylinder that is fixed to the handle by a base and a nut. The steel bolt at the bottom of the lock cylinder is locked to the handle fixing seat fixedly installed at the bottom of the handle groove on the lower panel of the handle. The above is a specific structural embodiment of the lock cylinder installed in the handle.

[0011] The handle has a locking washer and a lug washer at the nut fixing point, a retaining spring and a washer at the bolt fixing point, and anti-collision rubber pins on the top of the handle fixing seat to prevent collision with the handle. The above structure improves waterproof and quietness.

[0012] This utility model has a reasonable structural design, is convenient to use, install and assemble, has low production cost, good stability, and good sound and waterproof effect. In particular, the rotary impact and shockproof anti-accidental opening operation structure design is good. It is suitable for use as a metal cabinet door panel lock with rotary impact locking, and for structural improvement of similar products. Attached Figure Description

[0020] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-6As shown, the panel 13 of the panel lock is installed and fixed to the door panel. The top of the panel is provided with a handle groove. One side of the handle 9 in the handle groove is hinged at the pivot 18 and the handle torsion spring 17. The outer diameter of the curved side of the handle hinge in the handle groove of the panel is provided with a handle lever 19. The handle lever is aligned with the drive shaft 1602 that extends through the bottom of the panel. The drive shaft is located at one end corner of the rotating bracket 1601 of the rotating component 16 at the bottom of the panel. The panel at the point where the drive shaft extends has an arc-shaped hole 1301. One end of the drive shaft of the rotating component is fixed to the bottom of the panel by a positioning pin 1606 and swings. A rotating torsion spring 1605 for the swing of the rotating component is provided at the positioning pin. When the rotating component is lifted by rotating the handle, it drives the handle lever to abut against the drive shaft and rotate in the arc-shaped hole of the panel. At the same time, the rotating component drives the lock head of the rotating component to rotate and disengage from the lock hole 1501 at the fixed base bracket 15 fixed to the door frame. When the handle is released, the handle and the rotating component are reset by the handle torsion spring and the rotating torsion spring, respectively. Mounting screws 11 are provided at the corners of the square panel on the outer side of the handle groove.

[0021] The locking mechanism of the aforementioned rotating component consists of a guide wheel 1603 with an arc-shaped protrusion on one side of the rotating bracket above the drive shaft, corresponding to the arc-shaped hole on the lower panel, and a guide wheel mounting groove. The guide wheel and guide wheel mounting groove engage or disengage from the locking hole of the fixed bracket as the rotating bracket rotates. A through sliding pin 1607 is provided on the rotating bracket at the symmetrical other end of the drive shaft of the rotating component. A sliding hole 1608 is provided at the point where the sliding pin passes through, and one end of the sliding pin is inserted and fixed to the bottom of the panel. The rotating bracket of the rotating component is a sheet metal structure with curved shapes on both sides of the sliding hole and the guide wheel. The two sheet metal sides are connected and fixed by the sliding pin and the positioning pin. A connecting pin 1604 is provided between the two sheet metal sides at the guide wheel. A curved limiting side plate 1609 is provided on the drive shaft side of the rotating bracket of the rotating component. When the locking mechanism of the rotating component is inserted into the locking hole of the fixed bracket, the limiting side plate of the rotating bracket abuts against and limits the movement of the rotating bracket.

[0022] The handle is equipped with a lock cylinder 1 fixed to the handle by a base 2 and a nut 5. The steel bolt 7 at the bottom of the lock cylinder is locked to the handle fixing seat 12 fixed to the bottom of the handle groove on the lower panel of the handle. The nut fixing part of the handle is equipped with a stop washer 3 and a lug washer 4. The steel bolt fixing part is equipped with a retaining spring 8 and a washer 6. The top of the handle fixing seat is equipped with an anti-collision rubber nail 10 that collides with the handle.

[0023] When the handle drives the handle lever to rotate and lift it up to less than or equal to 15 degrees, there is no free travel between the handle lever and the drive shaft of the rotating component. After the angle is greater than 15 degrees, the handle lever drives the drive shaft. After the angle is greater than or equal to 45 degrees, the handle and the drive shaft are disengaged. The drive shaft is at a 15-degree angle with the positioning pin as the center along the arc hole of the panel, and the sliding hole of the rotating bracket is at a 45-degree angle with the positioning pin as the center.

[0024] This panel lock removes the latch assembly and replaces it with a rotating assembly, enabling both rotation-based unlocking and impact-based locking. When the door closes, the fixed bracket of the door frame directly impacts the rotating assembly at the bottom of the panel. The guide wheel of the rotating assembly rolls from one side of the inclined surface due to the lock hole at the fixed bracket, causing the guide wheel to rotate and enter the lock hole of the fixed bracket, locking it in place. In the above structure, the handle and handle lever are integrated by riveting. Simultaneously, when the handle is raised to ≤15°, there is a free travel between the handle lever and the drive shaft of the rotating assembly. When the angle exceeds 15°, the rotating assembly rotates via the drive shaft, which rotates 15° along the arc-shaped hole of the panel, unlocking the rotating assembly's lock. When the handle is raised to ≥45°, the handle is limited and cannot be opened. After the handle is released, it automatically resets.

[0025] In summary, the main mechanism of this panel lock is a rotary impact mechanism, applicable to industries such as engineering machinery, industrial cabinets, and automation control manufacturing, specifically related to doors and cabinets in these industries. The panel lock features a simplified structural design, optimized components, and convenient production and installation. It fulfills the functional requirement of impact-rotation locking, addressing the issue of indirect contact between the handle and the rotating component in high-vibration environments, thus resolving problems such as insufficient vibration resistance, accidental unlocking, and misoperation found in the market.
