Description

Technical Field

[0001] This utility model relates to a lock, and more particularly to a convenient lock. Background Technology

[0002] Locks are devices used for sealing, including locks, keys, and their accessories. Generally, they are defined as "sealing devices that can only be opened with a key." Besides keys, locks can also be opened using light, electricity, magnetism, sound, and fingerprint signals. Locks are not only protective devices but also serve management and decorative purposes. In international exchanges, there is a custom of presenting a symbolic "key" as a gesture of friendship. In outdoor or portable settings, locks that are easy to store, such as chain locks and locks with straps, are used. Traditional locks are generally large and inconvenient to carry. While smaller locks exist, their locking range is still limited, making it difficult to meet diverse usage needs. There is a lack of products that are convenient to carry and use, and have a wide range of applications. Utility Model Content

[0003] In view of the shortcomings of existing technology, this utility model provides a convenient lock.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a convenient lock, comprising a lock body and a folding body fixed thereon, wherein the folding body comprises a plurality of continuous folding units, the folding units being movably connected to each other, and the folding units having a folded state and an extended state; in the folded state, the folding units swing toward each other and the folding units are close together in the width direction; in the extended state, the folding units swing toward the two ends of the folding body, and the folding units tend to be parallel in the length direction.

[0005] The folding body has a positioning component and a locking component movably connected to both ends of the folding unit assembly.

[0006] The positioning element is hinged to the lock body for limiting the movement, and the locking element is fixed to the lock body by a snap-fit ​​connection.

[0007] The folding unit has an arc-shaped structure.

[0008] The folding unit has three points, namely point one, point two, and point three, which are movably connected and arranged in sequence. The folding unit rotates relative to point two, and the folding unit is connected to different folding units on both sides through points one and point three, respectively.

[0009] The folding units on the same side of the folding body all face one side.

[0010] The positioning element consists of two short rods hinged to the lock body.

[0011] The locking component consists of a short rod and a long rod that are hinged together, and one end of the long rod is provided with a locking part.

[0012] The latching part has a locking groove at its end, and the latching part has through-holes on the two side walls opposite to the locking groove. The latching part also has an inclined wedge surface on the opposite surface at its end.

[0013] The lock body is provided with a slot, and the slot wall is provided with a movable stop ball. The lock body is also provided with a push arm that drives the stop ball to move into the slot. The lock body includes a lock cylinder connected to the push arm, and the push arm has a linear return tendency through a spring.

[0014] The beneficial effects of this utility model are as follows: The convenient lock provided by this utility model adopts a hair clip or cross-arm telescopic structure. The working state and the folded storage state are no different from the shape of a hair clip. After folding and storing, it is small and exquisite and easy to carry, and can be directly put into clothing pockets. The lock is made of high-strength metal material and connected by a riveting structure, which meets the strength standard and is not easily damaged.

[0019] like Figures 1-4 As shown, a convenient lock includes a lock body 1 and a folding body 2 locked thereon. The folding body 2 includes several consecutive folding units 3, which are movably connected to each other. The folding units 3 have a folded state and an extended state. In the folded state, the folding units 3 swing towards each other and are close together in the width direction. In the extended state, the folding units 3 swing towards the two ends of the folding body 2 and tend to be parallel in the length direction. The main body of the folding mechanism is defined here, meaning that each unit has a specified folding and extending action, minimizing storage space and maximizing the application range. The design is facilitated by relative swinging or rotation, extending the path and increasing the number of stacked folding units 3 as much as possible.

[0020] The folding body 2 has a positioning member 4 and a locking member 5 movably connected to both ends of the folding unit 3 assembly. In this embodiment, the positioning member 4 relatively restricts one end of the folding body 2, while the other end is locked using the locking member 5 as needed. The positioning member 4 is hinged to the lock body 1 for positioning, and the locking member 5 is fixed to the lock body 1 by a snap-fit ​​connection. In this embodiment, all hinged connections are made with rivets to prevent loosening or forced prying. The lock body 1 adopts a combination lock for easy operation. The folding unit 3 has an arc-shaped structure, further compressing and utilizing space, and is also suitable for placement in a pocket. It should be noted that clothing pockets are generally much deeper than their opening width, and the folding unit 3 is designed with a length significantly greater than its width, which is beneficial for multi-section design to increase the application range without hindering storage.

[0021] The folding unit 3 has three movably connected points 6, 7, and 8 arranged sequentially. The folding unit 3 rotates relative to point 7. It is connected to other folding units 3 on either side via points 6 and 8 respectively. The folding unit 3 has three connection points, all of which rotate relative to each other, but the connection order is restricted; adjacent folding units 3 on different sides are connected end-to-end. In other words, the hairpin-type connection structure results in a crisscrossing shape when unfolded, which is more stable and reliable than a single-link structure.

[0022] The folding units 3 on the same side of the folding body 2 all face one side, resulting in a more regular layout and facilitating the concentration and optimization of space. The positioning element 4 consists of two short rods hinged to the lock body 1. The locking element 5 consists of a short rod and a long rod hinged together, with a locking part 9 at one end of the long rod. The locking part 9 provides locking and fixing, and in this embodiment, an elastic locking structure is used for cooperation and fixing.

[0023] The latching part 9 has a locking groove 10 at its end, and the latching part 9 has through-holes 11 on the two side walls opposite to the locking groove 10. The latching part 9 also has an inclined wedge surface 12 on the opposite surface at its end. The lock body 1 has a slot 13, and a stop ball 14 is provided on the wall of the slot 13 for limiting its movement. The lock body 1 also has a push arm 15 outside the lock body 1 to drive the stop ball 14 into the slot 13. The lock body 1 includes a lock cylinder 17 connected to the push arm 15. The push arm 15 has a linear return tendency through a spring 16. The locking holes 11 allow the stop ball 14 to enter and be locked. A protrusion corresponding to the shape of the locking groove 10 can also be provided at the bottom of the slot 13 of the lock body 1 to enhance the positioning effect. The design of the locking groove 10 and the wedge surface 12 is also to enhance the structural strength at this point. The push arm 15 is similar to a switch, and it is integrally connected to the lock cylinder 17, and together with the spring 16, it plays an elastic return role. It should be noted that the push arm 15 and the lock cylinder 17 have a Z-shaped structure, which facilitates the elastic contact of the spring 16.

[0024] After entering the correct password, pull the push rod backward to release the latch ball 14, which locks the bolt, and remove the bolt to open the lock. Insert the bolt into the keyhole, release the push rod, and the spring 16 will push the push rod forward, pressing the latch ball 14 to lock the lock. Then, scramble the password to prevent others from opening the lock.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
