[0025] The present invention is further described below in conjunction with the accompanying drawings: As shown in the figure, a U-shaped lock includes a matching lock beam 1 and a lock body 2, the lock beam is provided with a card slot 11, and also includes a lock tongue 21, which is movably mounted on the lock body, including a locked position in which it partially extends into the card slot and an unlocked position away from the card slot; an elastic member 3 is provided in the lock body and is used to apply force to keep the lock tongue in the locked position; an unlocking member 4 is rotatably mounted on the lock body, and when it rotates, it is used to drive the lock tongue to move and put it in the unlocked position, and at least part of the unlocking member is provided outside the lock body for manual operation. The lock beam has a U-shaped structure and has two legs with slots on them. The lock body has through slots for the legs to pass through and slide on the legs. Multiple slots can be set on the legs to adapt to different sizes of locked parts; the unlocking part can be rotatable, and when it is manually driven to rotate, the lock tongue will be moved away from the slot to unlock. At this time, you can continue to apply force on the unlocking part to drive the lock body to move on the lock beam, which is more convenient to use. The lock tongue is usually extended into the slot by the action of the elastic part to achieve locking, and is driven by the unlocking part to overcome the force of the elastic part and leave the slot. Two lock tongues can be set on the left and right, and both lock tongues are driven by the unlocking part.

[0026] In this embodiment, as shown in the figure, the lock body is provided with a slide groove 22 in the horizontal direction, and the lock tongue is slidably matched with the slide groove. At least part of the lock tongue is arranged in the slide groove, which plays a guiding role and makes the operation more stable.

[0027] In this embodiment, as shown in the figure, the unlocking member is provided with a push block 41, the locking tongue is provided with a first inclined surface 211, and the push block is provided with a second inclined surface 411 that cooperates with the first inclined surface. When the unlocking member rotates, the push block pushes the first inclined surface via the second inclined surface, thereby driving the locking tongue to move, resulting in a simple structure and easy installation.

[0028] In this embodiment, as shown in the figure, the lock body is provided with a rotation groove 23, and the unlocking member is provided with a rotating shaft 42 that matches the rotation groove. A wall can be provided in the lock body, and the rotation groove is provided on the wall, and then the rotating shaft rotates in the rotation groove.

[0029] In this embodiment, as shown in the figure, the lock body is provided with a through slot 24 for part of the unlocking member to extend out. A part of the unlocking member extends out of the through slot to form a handle, and the manual operation handle drives the unlocking member to rotate.

[0030] In this embodiment, as shown in the figure, a retaining wall 25 is provided in the lock body, one end of the elastic member presses against the retaining wall, and the other end presses against the lock tongue. The elastic member can be a spring, which plays a role in resetting.

[0031] This embodiment, as shown in the figure, also includes a combination lock assembly 6. The lock body is provided with a receiving slot for mounting the combination lock assembly. The operation of the combination lock assembly is conventional. The receiving slot (which may be formed by multiple walls) is used to mount the combination lock assembly. Once installed, a cover is installed to position the assembly. The lock body is provided with a through-slot through which the combination ring of the combination lock assembly is partially exposed.

[0032] In this embodiment, as shown in the figure, the lock body is further provided with a cover plate 27, which is integrally provided with a plurality of elastic paddles 28. The combination lock assembly includes a plurality of combination rings 61, each of which is provided with a shifting groove 611, and each of the paddles is provided with a shifting block 281 that cooperates with the shifting groove. When the combination ring is rotated into position, the shifting block falls into the shifting groove. This is a prior art, but the present application is characterized by the paddles and cover plate being integrally provided, which can be formed by injection molding for easy manufacturing.

[0033] In this embodiment, as shown in the figure, the combination lock assembly includes a movably mounted limit plate 62. The lock tongue is provided with an escape groove 212. The limit plate has a first position opposite the escape groove and a second position opposite the outer wall of the lock tongue, preventing the lock tongue from retracting. The limit plate can rotate (via a limit plate rotating shaft 622). A spring-mounted recess 621 is provided on the limit plate, driving it to the first position. When the password is correctly entered, the spring operates normally, causing the limit plate to be positioned opposite the escape groove, i.e., the first position, at which point the lock tongue can retract. If the password is incorrect, the limit plate, driven by the main shaft 66 of the combination lock assembly (which is provided with a cam 661), rotates. At this point, it is located behind the lock tongue to prevent it from retracting, preventing it from being unlocked. This is similar to a push-button combination lock and will not be described in detail.

[0034] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features.
