Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to an interlocking lock mechanism. Background Technology

[0002] Most door panels with installed lock bodies on the market, after installation and adjustment, have a satisfactory hinge overlap seal. However, due to differences in the types of materials used, the locking mechanism on the lock body side may have insufficient sealing or overlap, resulting in poor airtightness, watertightness, and sound insulation. Currently, the lock tongue on the market is not adjustable for sealing; instead, the seal is adjusted by adjusting the strike plate. However, the strike plate is only suitable for a limited range of materials, limiting its applicability. Furthermore, the lock tongue cannot be adjusted for length or shortening; instead, the strike plate is raised to improve the overlap, a cumbersome method with many parts, making adjustment inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a locking mechanism to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: This invention provides a locking mechanism, including a housing, a slider, a latch, a rotating sleeve, and an adjusting mechanism. The housing has an extension opening; the latch is connected to a locking rod slidably disposed within the housing; the slider is slidably disposed within the housing along the extension direction of the latch; the locking rod has an abutting portion that abuts against the slider; an elastic element is provided between the latch and the housing, the elastic element providing an elastic force that allows the abutting portion to abut against the slider, thereby causing the latch to extend from the extension opening; the rotating sleeve is rotatably disposed within the housing, the rotating sleeve having an actuating end that retracts the latch into the housing and a rotating end disposed outside the housing; the adjusting mechanism includes an adjusting hole disposed within the housing and an adjusting screw threadedly connected within the housing, the adjusting screw abutting against the slider.

[0005] The beneficial effects of this invention are: Rotating the rotating sleeve causes the bolt to extend into the protrusion. After the rotating sleeve returns to its original position, the bolt extends out of the protrusion under the action of the elastic element and locks with the strike plate. If insufficient bolt overlap occurs due to issues with the profile or strike plate, affecting anti-theft performance, a hexagonal key can be inserted through the adjustment hole into the adjustment screw inside the housing to extend or shorten the bolt, thus resolving the overlap problem. This adjustment method is simple and does not require disassembling the housing.

[0006] As a further improvement to the above technical solution, a baffle is provided inside the housing. The locking rod slides through the baffle and abuts against the slider. The elastic element abuts against both the baffle and the locking tongue. The baffle allows the locking rod to slide within the housing and facilitates the installation of the elastic element.

[0007] As a further improvement to the above technical solution, the slider is provided with a sliding hole, and the locking rod passes through the baffle and the sliding hole in sequence. The sliding hole serves as a guide and limiter, making it difficult for the abutting part to break free during the contact process with the slider.

[0008] As a further improvement to the above technical solution, the rotating end of the rotating sleeve is located between the slider and the baffle.

[0009] As a further improvement to the above technical solution, the rotating end of the rotating sleeve is provided with a slot, through which the locking rod passes. This results in a more compact structure, better enabling the slider to move and thus retracting the locking tongue into the housing.

[0010] As a further improvement to the above technical solution, a locking plate is also included, and the locking tongue engages with the locking plate.

[0011] As a further improvement to the above technical solution, the rotating end includes a rotating groove located on the outside of the housing. In use, a rod or other structure that engages with the rotating groove drives the rotating end to rotate, thereby causing the locking tongue to retract into the housing.

[0012] As a further improvement to the above technical solution, an adjustment plate is provided inside the housing, and the adjustment screw is threadedly connected to the adjustment plate, which facilitates the setting of the adjustment screw.

[0013] As a further improvement to the above technical solution, the latch extension surface of the housing is provided with an adjustable block, and the adjustable block has an extension opening. The adjustable block is adjustable up and down, and the latch is adjusted accordingly, reducing the gap between the latch and the strike plate and improving its sealing performance.

[0014] As a further improvement to the above technical solution, the housing includes an upper cover and a lower cover that overlap each other, the upper cover and the lower cover are provided with sliding grooves, and the slider is provided with a sliding protrusion that slides in the sliding grooves.

[0019] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0020] Most door panels with installed lock bodies on the market, after installation and adjustment, have a satisfactory hinge overlap seal. However, due to differences in the types of materials used, the locking mechanism on the lock body side may have insufficient sealing or overlap, resulting in poor airtightness, watertightness, and sound insulation. Currently, 600mm lock tongues on the market have non-adjustable sealing; adjustments are made by adjusting the strike plate. However, the strike plate is only suitable for a limited range of materials, limiting its applicability. Furthermore, 600mm lock tongues on the market cannot be adjusted for length or shortening. Improving the overlap is achieved by raising the strike plate, a cumbersome method with many parts, making adjustment inconvenient.

[0021] Therefore, refer to Figures 1 to 7 The overlapping lock body mechanism of the present invention is provided in the following embodiment: In some embodiments, a locking mechanism includes a housing, a slider 700, a latch 600, a rotating sleeve 800, an adjusting mechanism, and a locking plate, wherein the latch 600 engages with the locking plate to achieve locking.

[0022] The housing includes an upper cover 100, a lower cover 200, and a front cover plate 300. The upper cover 100 and the lower cover 200 can be interlocked or connected by threads. The front cover plate 300 is located on the front side of the upper cover 100 and the lower cover 200, and the front side is the protruding surface of the latch. The front cover plate 300 is provided with an adjusting block 400, which has an extension opening through which the latch 600 extends. The adjusting block 400 is adjustable up and down, and the latch 600 is also adjusted up and down accordingly to reduce the gap between the latch 600 and the strike plate, thereby improving its sealing performance. The adjusting block 400 has oblong holes 410 at both ends. Two Phillips head countersunk screws 420 pass through the oblong holes 410 and are threaded into the adjusting holes 310 of the front cover plate 300 to fix the adjusting block 400 to the front cover plate 300. During adjustment, loosen the Phillips countersunk screw 420, move the adjusting block 400 up and down to the appropriate position, and then tighten the Phillips countersunk screw 420 again. The adjustment is simple and convenient.

[0023] For details, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 7 ,in Figure 5 This is a schematic diagram of the structure before vertical adjustment. Figure 6 The display shows that the latch has been adjusted up and down by two millimeters. Figure 7 This is a schematic diagram of the structure after vertical adjustment. The adjustment is achieved by loosening the Phillips head countersunk screw 420, adjusting the position of the adjusting block 400, and finally tightening the Phillips head countersunk screw 420. Figure 7 Requirements: To address the problem in traditional latch structures where the large gap between the bolt 600 and the strike plate leads to excessive door clearance, causing wobbling and affecting the seal.

[0024] Both the upper cover 100 and the lower cover 200 are provided with sliding slots 110. The slider 700 has sliding protrusions 710 on both its upper and lower sides that are slidably disposed within the sliding slots. The slider 700 slides along the extension direction of the latch 600. In some other embodiments, slide rails extending forward and backward can be provided within the upper cover 100 and the lower cover 200, with the slider 700 slidably disposed on the slide rails to improve sliding stability.

[0025] The upper cover 100 and the lower cover 200 are also fitted with a baffle 120, which has a through hole. The locking tongue 600 is connected to a slidably mounted locking rod 610. The locking rod 610 has an abutment portion that abuts against the slider 700. After the locking rod 610 slides through the through hole, the abutment portion abuts against the slider 700. The abutment portion is an abutment protrusion 611. The elastic element 900 provides elastic force for the abutment portion to abut against the slider 700, thereby causing the locking tongue 600 to extend from the protrusion. The elastic element 900 includes a spring, which abuts against both the baffle 120 and the locking tongue 600. The baffle 120 allows the locking rod 610 to slide within the housing and facilitates the installation of the elastic element 900. The spring is sleeved on the locking rod 610 for greater stability. In some other embodiments, the elastic element 900 may also be a spring sheet.

[0026] A rotating sleeve 800 is rotatably mounted on the housing. The rotating sleeve 800 has an actuating end that retracts the locking tongue 600 into the housing and a rotating end located outside the housing. The rotating end of the rotating sleeve 800 is located between the slider 700 and the baffle 120. The rotating end of the rotating sleeve 800 has a slot 810 through which the locking rod 610 passes. The structure is more compact and better drives the slider 700 to move, thereby causing the locking tongue 600 to retract into the housing.

[0027] The rotating end includes a rotating groove 820 located on the outside of the housing. In use, a rod or other structure that can be engaged with the rotating groove 820 can drive the rotating end to rotate, thereby causing the locking tongue 600 to retract into the housing.

[0028] The adjustment mechanism includes an adjustment hole 310 located in the housing and an adjustment screw 320 threadedly connected to the housing. The adjustment screw 320 abuts against the slider 700. Specifically, an adjustment plate 330 is provided inside the housing. The upper and lower ends of the adjustment plate 330 are respectively engaged with the upper cover 100 and the lower cover 200. The adjustment screw 320 is threadedly connected to the adjustment plate 330, facilitating its installation. The nut of the adjustment screw 320 is positioned opposite the adjustment hole 310. The adjustment hole 310 can be oblong-shaped, allowing the hexagonal key 500 to easily extend through the adjustment hole 310 to adjust the adjustment screw 320 inside the housing after the latch 600 has been adjusted up and down.

[0029] Adjustment details such as Figure 2 The overlap between the 600 latch and the strike plate is only 1.5mm, which can cause the door to not close properly and result in poor security. This can be addressed by adjusting the hex key 500. Figure 3 Extend the latch 600 by 1.5mm. The overlap should reach 3mm, refer to... Figure 2 It offers better overlap and higher security. The locking bolt 600 can be extended or shortened by ±3mm by adjusting the adjusting screw 320 inside the lock body using a hex key 500, thus solving the overlap problem.

[0030] Rotating the rotating sleeve 800 causes the latch 600 to extend into the protrusion. After the rotating sleeve 800 returns to its original position, the latch 600 extends out of the protrusion under the action of the elastic element 900 and locks with the strike plate. If the latch 600 does not overlap sufficiently due to issues with the profile or strike plate, affecting the anti-theft performance, the latch 600 can be extended or shortened by inserting the hexagonal key 500 through the adjustment hole 310 into the adjustment screw 320 inside the housing, thus resolving the overlap problem. This adjustment method is simple and does not require disassembling the housing for adjustment.

[0031] Advantages of this invention: The adjustable overlap can be achieved by rotating the adjusting screw 320 with a hex key 500 to adjust the latch 600 up and down to meet the overlap requirements. The adjustable seal can be improved by loosening the Phillips head countersunk screw 420, moving the adjusting block 400, and then tightening the Phillips head countersunk screw 420.

[0032] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
