And the requirements of different environment installation positions are met.

Description

Technical Field

[0001] This utility model relates to door locks, specifically to a curved three-point lock. Background Technology

[0002] Current door lock technology lacks design options for curved door locks. Curved door locks are primarily used on curved doors in military cargo holds and special vehicles and vessels. A curved door refers to a flat door with an angled bend at the top or bottom, and curved door locks are designed specifically for such angled curved doors.

[0003] The current hatch door locks lack designs specifically for doors with curved surfaces at this angle.

[0004] Currently, there are few door lock structures for curved doors, and they are relatively expensive. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a curved surface three-point lock.

[0006] Technical Solution: The curved three-point lock of this utility model adds a connecting piece at the bend of the curved surface of the lock rod in a conventional three-point lock, allowing the primary and secondary lock rods, which are not on the same plane, to move simultaneously for locking and unlocking. The connecting piece includes a Z-end and an L-end of the lock rod, which are connected to the primary and secondary lock rods respectively by screws.

[0007] Furthermore, the Z end of the locking rod has a screw mounting hole at one end to connect with the secondary locking rod, and a U-shaped groove at the other end, with mounting screw holes on both sides of the U-shape, which are engaged with the groove at the L end of the locking rod by screws.

[0008] Furthermore, one end of the locking rod L is connected to the primary locking rod via a screw, and the other end has a slotted hole for connection to the locking rod Z end.

[0009] Furthermore, one end of the primary locking rod is connected to the three-pronged lock body, and the other end is connected to the locking rod L end.

[0010] Furthermore, the three-pronged lock body is manually rotated to move the first-level and third-level locking rods, while simultaneously causing the internal bolt to pop out and retract.

[0011] Furthermore, one end of the three-stage locking rod is connected to the three-pronged lock body, and the other end contacts the lower locking stop when locked.

[0012] Furthermore, one end of the secondary locking rod is connected to the Z end of the locking rod, and the other end contacts the upper locking stop when locked.

[0013] Furthermore, it also includes a bracket for guiding the locking bar.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This product is suitable for installation on curved doors, offering ease of use and meeting the requirements of various installation locations. Based on the original three-pronged lock, this product improves upon the lock bar by adding two connectors (Z-shaped and L-shaped connectors) at the bar's bend, allowing the lock bar, even when not on the same plane, to move synchronously with the lock body for locking and unlocking. Both the Z-shaped and L-shaped connectors are made of national standard 06Cr19Ni10 material, possessing excellent corrosion resistance and heat resistance. This invention enables curved doors to achieve the same convenient closing, opening, and locking functions as flat doors, while offering high overall structural strength, strong versatility, and wide applicability.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described below.

[0027] The curved surface three-point lock of this embodiment includes the following structure:

[0028] Level 1 Locking Rod 1: The locking rod is made of 304 stainless steel and has a specially designed concave shape. One end is connected to the three-pronged lock body 5 and the other end is connected to the locking rod L end 4 (Level 1 Locking Rod 1 is fixed to the locking rod L end 4 and the three-pronged lock body 5 by bolts). The two are fixed with screws.

[0029] Secondary locking bar 2: The locking bar is made of 304 stainless steel and has a special concave shape. One end is connected to the Z end 3 of the locking bar, and the other end is in contact with the upper locking stop 8 when locked.

[0030] Locking rod Z end 3: The locking rod Z end 3 connector is made of 304 stainless steel and is roughly Z-shaped. It is one of the main connectors for the turning connection. One end has a screw mounting hole to connect with the secondary locking rod 2 (fixed by bolts). The other end has a U-shaped groove on the Z-shaped end and mounting screw holes on both sides of the U-shape. It is engaged with the groove of the locking rod L end 4 connector by screws, so that the two locking rods that are not on the same plane can move synchronously through these two connectors to achieve the function of opening and closing the curved surface lock.

[0031] Locking rod L end 4: The locking rod L end 4 connector is made of 304 stainless steel and is roughly L-shaped. It is one of the main connectors for turning connections. One end is connected to the first-level locking rod 1 by a screw, and the other end has a slotted hole to connect to the other locking rod Z end 3 connector.

[0032] Three-pronged lock body 5: The three-pronged lock body 5 is made of 304 stainless steel. Its main function is to drive the first-level lock bar 1 and the third-level lock bar 6 by manually rotating the lock body, and at the same time drive the internal lock tongue to pop out and retract.

[0033] Level 3 locking bar 6: The locking bar is made of 304 stainless steel and has a special concave shape. One end is connected to the three-pronged lock body 5, and the other end contacts the lower locking stop 9 when locked.

[0034] Bracket 7: The three brackets are made of 304 stainless steel. Their main function is to guide the locking rod. Bracket 7 is fixed to the door panel with screws and is in surface contact with the locking rod. It guides the locking rod when it moves.

[0035] Upper locking position 8 and lower locking position 9: Upper locking position 8 and lower locking position 9 are made of nylon (other materials can also be used as needed). They come into contact with the locking rod when the door is closed. The door can be locked by simply making contact.

[0036] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
