When dimension A is smaller than dimension B, the left latch disengages from the first locking interface first without making a popping sound, while the right latch is still locked inside the second locking interface; when the rotating shaft continues to push the right latch out of the second locking interface, the lock beam makes an unlocking sound as normal.

Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically a U-shaped lock that overcomes delayed response. Background Technology

[0002] In existing technologies, U-shaped locks are widely used. Traditional U-shaped locks require manual removal of the U-ring after unlocking with a key, and when locking, the U-ring must be inserted into a fixed position on the lock body, and the key must be manually used to lock. Both the unlocking and locking processes are relatively cumbersome, resulting in a poor user experience. Utility Model Content

[0014] Optionally, the right locking tongue further includes:

[0015] Top groove one, which is opened on one side of the outer wall of the right locking tongue;

[0016] Spring groove one is located on the top of the outer wall of the right latch;

[0017] One locking connector is located on the other end face of the right locking tongue;

[0018] The locking connector is shaped like a frustum, which can effectively position the rotating shaft while creating friction between the right locking tongue and the locking beam.

[0019] Optionally, the left locking tongue includes:

[0020] Positioning pin two is located on one end face of the left locking tongue;

[0021] The left spring is positioned above the second positioning post;

[0022] The second protective pad, placed on the left latch, effectively buffers the gap between the lock beam and the left latch, while also protecting the left latch.

[0023] Optionally, the left locking tongue further includes:

[0024] Top groove two is located on one side of the outer wall of the left locking tongue;

[0025] Spring groove two is located on the top of the outer wall of the left latch;

[0026] A second locking connector is located on the other end face of the left locking tongue, and the second locking connector is a truncated cone-shaped protrusion.

[0027] It can effectively position the pivot while creating friction between the left latch and the locking beam.

[0028] Optionally, the bottom of the rotating shaft is provided with two positioning shafts, which are respectively embedded in the top groove one and the top groove two, so as to effectively achieve the positioning effect of the positioning shafts.

[0029] (III) Beneficial Effects

[0030] Compared with the prior art, this utility model provides a U-shaped lock that overcomes delayed response, and has the following beneficial effects:

[0031] This utility model uses a left and right locking tongue. The rotating shaft pushes the left and right locking tongues with the same stroke. When size A is smaller than size B, the left locking tongue will disengage from the first locking interface first without making a popping sound, while the right locking tongue is still locked inside the second locking interface. When the rotating shaft continues to push the right locking tongue out of the second locking interface, the lock beam will make an unlocking sound as normal. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example: Please refer to Figures 1 to 4 The present invention provides a technical solution: a U-shaped lock for overcoming delayed response, comprising a lock beam 1.

[0039] Locking beam 1 is hook-shaped in general. A right locking tongue 2 is provided on the right side of the middle part of locking beam 1, and a left locking tongue 3 is provided on the left side of the middle part of locking beam 1.

[0040] A pivot 4 is provided between the right latch 2 and the left latch 3. By rotating the pivot 4, the right latch 2 and the left latch 3 are respectively embedded into the interior of the locking beam 1, thereby achieving the open or closed state of the locking beam 1.

[0041] Based on the above embodiments, in this embodiment, a locking interface 101 is opened on one side of the locking beam 1, and anti-slip particles 103 are provided inside the locking interface 101. A locking interface 2 102 is opened on the other side of the locking beam 1. The locking interface 101 and the locking interface 2 102 are symmetrically arranged. When the right locking tongue 2 and the left locking tongue 3 are embedded in the locking interface 101 and the locking interface 2 102, the stability between the right locking tongue 2 and the left locking tongue 3 and the locking beam 1 can be effectively improved, and the phenomenon of the right locking tongue 2 and the left locking tongue 3 disengaging can be avoided.

[0042] Based on the above embodiments, the right locking tongue 2 in this embodiment includes:

[0043] Positioning pin 201 is located on one end face of the right locking tongue 2;

[0044] The right spring 202 is positioned above the positioning post 201;

[0045] Protective pad 203 is positioned above the right latch 2, which also includes:

[0046] Top groove 204 is located on one side of the outer wall of the right locking tongue 2;

[0047] Spring groove 205 is formed on the top of the outer wall of the right locking tongue 2;

[0048] The snap connector 206 is located on the other end face of the right locking tongue 2, and the snap connector 206 is shaped like a frustum.

[0049] The pivot 4 pushes the left latch 3 and the right latch 2 by the same amount of stroke. When dimension A is smaller than dimension B, the left latch 3 will disengage from the locking interface 101 first and will not make a popping sound. At this time, the right latch 2 is still locked inside the locking interface 102. When the pivot 4 continues to push the right latch 2 out of the locking interface 102, the lock beam 1 will make an unlocking sound as normal.

[0050] Based on the above embodiments, the left locking tongue 3 in this embodiment includes:

[0051] Positioning pin 2 301 is located on one end face of the left locking tongue 3;

[0052] Left spring 302 is positioned above positioning post 301;

[0053] Protective pad 2 303 is positioned above the left locking tongue 3, which also includes:

[0054] Top groove 2 304, which is opened on one side of the outer wall of the left locking tongue 3;

[0055] Spring groove 305 is located on the top of the outer wall of the left locking tongue 3;

[0056] The second snap-fit ​​connector 306 is located on the other end face of the left locking tongue 3, and the second snap-fit ​​connector 306 is shaped like a frustum.

[0057] The pivot 4 pushes the left latch 3 and the right latch 2 by the same amount of stroke. When dimension A is smaller than dimension B, the left latch 3 will disengage from the locking interface 101 first and will not make a popping sound. At this time, the right latch 2 is still locked inside the locking interface 102. When the pivot 4 continues to push the right latch 2 out of the locking interface 102, the lock beam 1 will make an unlocking sound as normal.
