Description

Technical Field

[0001] The present invention relates to the technical field of luggage locks, and in particular to a tool-free and easy-to-disassemble luggage lock. Background Art

[0002] At present, due to the high safety performance and convenient operation, password-type luggage locks are widely used on various luggage to provide security for the luggage. The existing luggage locks generally include a base and a lock body, the base is provided with a receiving groove with an opening facing upward, and the lock body is embedded in the receiving groove. For example, the password luggage lock disclosed in the Chinese patent document with announcement number CN220599502U.

[0003] Traditionally, the base and the lock body are fixed with screws, which makes the manufacturing and assembly operations inconvenient. Later, a structure in which the lock body and the lock base are connected by a card is introduced, which does not require screws during assembly and is more convenient to operate.

[0004] However, due to the limitation of the clamping structure between the existing base and the lock body, a special tool is required to disassemble the lock. In the prior art, a locking slide is provided between the base and the lock body to clamp the lock body longitudinally, and a window is provided at the bottom of the base. The locking slide and the base are clamped in the horizontal direction by one-way teeth. When disassembling the lock, a special tool is required to be inserted from the bottom to the top through the window of the base, and the side wall of the base is pushed outward to separate and release the meshing of the one-way teeth, so that the locking slide can be pushed horizontally, thereby releasing the restriction on the lock body. It should be noted that the locking slide in the prior art is similar to a U-shaped / I-shaped one. Since the window of the base is provided at the bottom, the special tool is inserted from the bottom to the top to press against the locking slide and the side wall of the base, and can only press against the position of the locking slide near the bottom. Under the influence of the force arm, even if a large pressure is applied to the locking slide, it can only make the two side arms of the U-shaped tilt, which is not enough to tighten and deform to separate the one-way teeth, so it can only squeeze the side wall of the base to deform, and therefore a tool must be used to squeeze the side wall of the base from the inside to the outside. Furthermore, since the window of the base in the prior art is set at the bottom, the strength of the base is greatly weakened, and the strength of the base needs to be compensated by the U-shaped / I-shaped shape of the locking slide. Therefore, the shape of the locking slide is limited by the position of the base window, and its structural shape is difficult to change.

[0005] In summary, the existing luggage locks without screw clamping require special tools to be disassembled, and have complex structures and high costs. Summary of the invention

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] The present embodiment is a tool-free and easy-to-disassemble luggage lock, such as Figures 1 to 5 As shown, it includes a base 1 and a lock body 2, both of which are long strips. The base 1 includes a bottom wall 12, two long side walls 13 and an end side wall 14 that together form a receiving groove 11 with an opening facing upward. The lock body 2 is embedded in the receiving groove 11 with the top exposed. A flange 21 is provided on the top peripheral side of the lock body 2, and the flange 21 cooperates with the top surface of the base 1.

[0039] A locking member 3 capable of sliding along the length direction of the base 1 is provided between the outer side surface of the lock body 2 and the long side wall 13 of the base 1. The locking member 3 is an integrated structure and is U-shaped as a whole. It includes a first arm body 31, a second arm body 32 and a connecting section 33. The connecting section 33 connects the ends of the first arm body 31 and the second arm body 32. The first arm body 31 and the second arm body 32 are arranged symmetrically and are respectively located on the long side walls 13 of the base 1 facing each other.

[0040] The long side wall 13 of the base 1 is provided with a first clamping portion 15, and the first arm 31 and the second arm 32 are provided with a second clamping portion 34. The first clamping portion 15 and the second clamping portion 34 are meshing helical teeth, which are used to prevent the locking member 3 from sliding in one direction (not preventing in the forward direction, but preventing in the reverse direction). The locking member 3 is provided with a first interlocking structure 35, and the lock body 2 is provided with a second interlocking structure 22. The first interlocking structure 35 includes a trapezoidal boss located on the locking member 3, and the second interlocking structure 22 includes an oblique groove located on the lock body 2. The trapezoidal boss can be inserted into the oblique groove along the length direction of the base 1, thereby limiting the lock body 2 from longitudinally disengaging from the receiving groove 11. The first clamping portion 15 and the second clamping portion 34 in this example are helical teeth, which can actually be changed to buckles.

[0041] When the lock body 2 and the base 1 need to be assembled, the lock body 2 is placed in the receiving groove 11, and the locking member 3 slides forward to the preset position: the first interlocking structure 35 and the second interlocking structure 22 are interlocked along the length direction of the base 1 to limit the lock body 2 from longitudinally escaping from the receiving groove 11; and the first clamping portion 15 and the second clamping portion 34 are engaged to limit the reverse movement of the locking member 3, so that the base 1, the locking member 3 and the lock body 2 can be fixed.

[0042] In this embodiment, the locking member 3 is provided with a fulcrum protrusion 36 at the side of the second clamping portion 34, and a clearance space 4 is left between the position where the locking member 3 is provided with the second clamping portion 34 and the outer side surface of the lock body 2. The long side wall 13 of the base 1 is provided with a window 16, and the position of the locking member 3 adjacent to the second clamping portion 34 is provided with an operating protrusion 37, which is penetrated at the window 16 and exposed to the outside, and the outer wall surface of the operating protrusion 37 is flush or substantially flush with the outer wall surface of the second vertical portion 133.

[0043] When the lock body 2 needs to be removed, an external force presses the operating protrusion 37 inward from the window 16, so that the fulcrum protrusion 36 presses against the outer wall of the lock body 2, and the position where the second clamping portion 34 of the locking member 3 is provided is deformed toward the clearance space 4, thereby releasing the clamping relationship between the first clamping portion 15 and the second clamping portion 34, and the locking member 3 can be moved in the reverse direction to separate the first interlocking structure 35 from the second interlocking structure 22, and the lock body 2 can be removed.

[0044] Compared with the prior art, the first clamping portion 15 of the base 1 and the second clamping portion 34 of the locking member 3 can be separated by directly pressing the locking member 3 manually without the aid of external tools. The operation is simple, no special tools are required, and the manufacturing cost is reduced.

[0045] In this embodiment, an installation notch 17 is formed on the end side wall 14 of the base 1, and the locking member 3 is inserted into the base 1 through the installation notch 17, and the connecting section 33 partially protrudes from the installation notch 17 as a button. During assembly, the lock body 2 can be clamped by pressing the connecting section 33 toward the base 1.

[0046] In this embodiment, the fulcrum protrusion 36 includes a first fulcrum portion 361 and a second fulcrum portion 362 which are separated and arranged on both sides of the second clamping portion 34, that is, the second clamping portion 34 is located between the first fulcrum portion 361 and the second fulcrum portion 362, and the second clamping portion 34 is more likely to arch and deform when pressed.

[0047] In this embodiment, the long side wall 13 of the base 1 includes a first vertical portion 131, a first horizontal portion 132, a second vertical portion 133 and a second horizontal portion 134 arranged in sequence from bottom to top; the first vertical portion 131 forms a U shape with the bottom wall 12 (the opening size is substantially the same as that of the lock body 2), the first horizontal portion 132 extends outward and is arranged horizontally, the second horizontal portion 134 and the first horizontal portion 132 are arranged vertically opposite to each other, the first horizontal portion 132, the second vertical portion 133 and the second horizontal portion 134 form a directional groove with an opening facing inward, the locking member 3 can be slidably embedded in the directional groove, and the second horizontal portion 134 is used as a directional structure to limit the longitudinal position of the locking member 3. The window 16 is arranged through the first horizontal portion 132 and the second vertical portion 133, and the window 16 cannot penetrate the bottom wall 12 of the base 1, otherwise it will affect the strength of the base 1, and there is no need to penetrate the first vertical portion 131.

[0048] In this embodiment, the locking member 3 is supported by the first transverse portion 132, and a distance is left between the inner side surface of the locking member 3 and the inner side surface of the first vertical portion 131, thereby freeing up the clearance space 4. The fulcrum protrusion 36 is flush or substantially flush with the inner side surface of the first vertical portion 131.
