Detailed Description

Example 1; as shown in fig. 1-3, a door lock catch plate guide piece comprises a buckle plate 1, wherein the buckle plate 1 is provided with a lock hole 3 for matching with an oblique tongue 2, the lock hole 3 is provided with a guide mechanism 4 for reducing friction force between the oblique tongue 2 and the lock hole 3, the guide mechanism 4 reduces friction force between the oblique tongue 2 and the lock hole 3, when the oblique tongue 2 is deformed or displaced after long-term use and then is clamped in the lock hole 3, the guide mechanism 4 still enables the oblique tongue 2 to pass in and out of the lock hole 3 smoothly, the oblique tongue 2 is provided with an arc surface part and a corresponding plane part, the friction force between the oblique tongue 2 and the lock hole 3 is from matching between the plane part of the oblique tongue 2 and the hole wall of the lock hole 3, and the buckle plate 1 is equivalent to a decorative panel assembled outside a door frame.

The guide mechanism 4 comprises a rolling part 5 matched with the latch bolt 2, the latch bolt 2 is matched with the rolling part 5 to reduce the friction force between the latch bolt and the lock hole 3, and the rolling part 5 can adopt a ball and roller mode.

The guide mechanism 4 comprises a pin shaft 6 for rotating the rolling parts 5, and a plurality of rolling parts 5 can be arranged on one pin shaft 6.

The pin shaft 6 is fixedly assembled with the pinch plate 1, and the pin shaft 6 and the pinch plate 1 can be fixed in various ways, such as welding and the like.

The buckle plate 1 is provided with a limiting groove 7 for preventing the pin shaft 6 from transversely deviating, the pin shaft 6 is limited through matching with the limiting groove 7, the longitudinal direction of the buckle plate 1 is the longitudinal direction, the transverse direction of the buckle plate 1 is the width direction, and the limiting groove 7 mainly keeps the pin shaft 6 of the rolling part 5 to be parallel to the longitudinal direction.

The limiting groove 7 is internally provided with a blocking part 8 for preventing the pin shaft 6 from longitudinally deviating, the pin shaft 6 is limited through matching with the blocking part 8, and the blocking part 8 mainly prevents the rolling part 5 from longitudinally separating from the limiting groove 7.

The guide mechanism 4 comprises a protruding mechanism 9 for fixing the pin shaft 6, and the protruding mechanism 9 is used for assembling the pin shaft 6.

Protruding mechanism 9 and buckle 1 formula structure as an organic whole, buckle 1 generally adopts the metal material, can form protruding mechanism 9 through the bending, and processing is convenient.

The guiding mechanism 4 sets up in lockhole 3 and for the fore-and-aft both sides of buckle 1, and a tool to lock 10 and buckle 1 after the installation only have the guiding mechanism 4 of one side just to play a role to latch bolt 2, so set up both sides, be for adapting to the buckle 1 that left right direction opened the door, let buckle 1 have the commonality, the practicality is strong.

The rolling member 5 has a cylindrical cross section, and the rolling member 5 preferably has a cylindrical structure in order to increase the matching surface between the rolling member 5 and the latch tongue 2.

During assembly, the rolling parts 5 are firstly strung on the pin shaft 6, then the pin shaft 6 is arranged in the limiting groove 7, and the protruding mechanism 9 is bent through a tool to fix the pin shaft 6.

Example 2; as shown in fig. 4, the difference between this embodiment and embodiment 1 is that the guiding mechanism is directly installed in the lock hole of the door frame corresponding to the latch bolt, and can be directly manufactured before the door frame leaves the factory, and the guiding mechanism is installed on the inner wall of the lock hole of the door frame, which is equivalent to using the door frame as a buckle plate, and the installation manner is similar.
