The lock tongue 30 and the lock hook 20 are reliably connected, and the assembly operation is convenient. When the lock tongue 30 and the box body 10 need to be separated, the lock tongue 30 and the box body 10 are assembled. Figure 6In (b), the lock hook 20 is switched to the unlocking position, and the guide portion 32 in the lock tongue 30 can be pushed out of the guide groove 11 through the port 111 of the box body 10, combined with Figure 6 (c) in the figure makes the lock tongue 30 and the box body 10 separate, and the disassembly operation is convenient. The ornament with the lock buckle 100 is convenient to operate when the lock buckle 100 is disassembled and assembled, the lock buckle 100 is reliably connected, the ornament is not easy to be separated from the user, and the user has a good experience.

[0044] In some embodiments, see Figures 1 to 5 The first direction X may be the length direction of the box body 10 , the second direction Y may be the width direction of the box body 10 , and the third direction Z may be the thickness direction of the box body 10 .

[0045] The first direction X, the second direction Y and the third direction Z may be perpendicular to each other.

[0046] In some embodiments, see Figure 3 , Figure 6 In (a), when the guide portion 32 is located in the guide groove 11, in the first direction X, the pivot axis 20a of the lock hook 20 can be located between the head 321 of the guide portion 32 and the end 322 of the guide portion 32. The head 321 and the end 322 of the guide portion 32 are the opposite ends of the guide portion 32 in the first direction X.

[0047] The guide portion 32 is set to be relatively long, so that when the guide portion 32 is installed into the guide groove 11, through the sliding cooperation between the guide portion 32 and the guide groove 11, the head 321 of the guide portion 32 can exceed the position of the pivot axis 20a of the lock hook 20, which is convenient for guiding the lock tongue 30 into the guide groove 11 of the box body 10, thereby improving the convenience of assembly.

[0048] The cross-sectional shape of the guide portion 32 is adapted to the cross-sectional shape of the guide groove 11 , for example, both are rectangular or other non-circular shapes, so that the guide portion 32 can be slidably installed in the guide groove 11 and the guide portion 32 cannot rotate relative to the box body 10 .

[0049] In some embodiments, see Figure 1 , Figure 2 , Figure 7 In (a) to (c), the first buckle portion 21 has a first guide surface 211, and the second buckle portion 31 has a second guide surface 311. When the guide portion 32 enters the guide groove 11 from the port 111, the first guide surface 211 and the second guide surface 311 are in sliding contact, so that the lock hook 20 rotates a predetermined angle and the second buckle portion 31 can enter the guide groove 11.

[0050] Combination Figure 7In (a) and (b), when the locking tongue 30 is pushed into the top opening 112 of the box body 10 along the first direction X, the guide portion 32 and the guide groove 11 are slidably matched, and the first guide surface 211 and the second guide surface 311 abut to enable the locking hook 20 to rotate ( Figure 7 Counterclockwise rotation) preset angle, combined with Figure 7 (c) in the figure makes it easy for the second buckle part 31 and the first buckle part 21 to be buckled together, and the lock tongue 30 is pushed into the guide groove 11, and the lock hook 20 is switched to the locked position under the action of the elastic member 40. The user can install the lock tongue 30 into the box body 10 with one hand to realize the buckling of the second buckle part 31 and the first buckle part 21, and the assembly operation is convenient, and the user experience is good.

[0051] See also Figure 2 The first guide surface 211 may be disposed on a side of the first buckle portion 21 close to the port 111. The first guide surface 211 may be an inclined surface, a curved surface or other shapes. Figure 1 The second guide surface 311 can be disposed on one side of the second buckle portion 31 close to the head portion 321 of the guide portion 32. The second guide surface 311 can be an inclined surface, a curved surface or other shapes.

[0052] In some embodiments, see Figures 1 to 3 The box body 10 includes a bottom wall 12 and a pair of first side walls 13, the two first side walls 13 are respectively connected to the opposite sides of the bottom wall 12, and the inner surface of at least one first side wall 13 extends to form a guide wall 14, and the guide wall 14, the first side wall 13 and the bottom wall 12 form a guide groove 11. The width D1 of the second buckle portion 31 is smaller than the width D2 of the guide portion 32.

[0053] The width D1 of the second buckle portion 31 is the dimension of the second buckle portion 31 in the second direction Y. The width D2 of the guide portion 32 is the dimension of the guide portion 32 in the second direction Y.

[0054] The box body 10 having the bottom wall 12, the first side wall 13 and the guide wall 14 has a simple structure, and can realize the sliding fit between the guide portion 32 of the lock tongue 30 and the guide groove 11 of the box body 10, so that the lock tongue 30 can be conveniently installed in the guide groove 11 of the box body 10. The lock tongue 30 arranged in the guide groove 11 cannot be separated from the box body 10 through the top opening 112.

[0055] Exemplarily, the two first side walls 13 are extended away from the edge of the bottom wall 12 to form a guide wall 14. The bottom wall 12, the two first side walls 13 and the two guide walls 14 together form a guide groove 11.

[0056] Exemplarily, one of the first side walls 13 is extended away from the edge of the bottom wall 12 to form a guide wall 14. The bottom wall 12, the two first side walls 13 and the guide wall 14 together form a guide groove 11.

[0057] In some embodiments, see Figures 1 to 3 , Figure 6 The box body 10 further includes an end wall 17, which is connected between the two first side walls 13, and the end wall 17 and the port 111 are arranged opposite to each other along the first direction X. The end wall 17 can prevent the locking tongue 30 located in the guide groove 11 from escaping from the box body along the first direction X. The end wall 17 can also cover the end of the guide groove 11 to provide a better appearance effect.

[0058] In some embodiments, see Figure 8 The guide groove 11 has a first area 11b and a second area 11c distributed and connected along the first direction X, the first area 11b is arranged away from the port 111, and the second area 11c is arranged close to the port 111. The first area 11b is a milling area for an end mill, and the second area 11c is a milling area for a T-type mill.

[0059] See also Figure 8 , looking at the box body 10 from the bottom surface 11a of the guide groove 11, all structures of the guide groove 11 in the first area 11b can be fully seen, but all bottom surfaces 11a of the guide groove 11 in the second area 11c cannot be fully seen, but part of the structure of the second area 11c (guide wall 14) blocks part of the bottom surface 11a of the guide groove 11. When manufacturing the box body 10 of metal material, the slots in the first area 11b can be CNC milled by an end mill, and the slots in the second area 11c can be CNC milled by a T-type milling cutter. Compared with the metal box body cast by the lost wax method, the metal box body 10 of this embodiment is processed by a CNC machine tool, and the processing efficiency and processing accuracy are improved.

[0060] On the bottom surface 11a of the guide groove 11, the edge projection of the top opening 112a corresponding to the first area 11b can surround the edge projection of the bottom surface 11a1 of the first area 11b. The bottom surface 11a1 of the first area 11b is located opposite to the top opening 112b. For example, the edge projection of the top opening 112a corresponding to the first area 11b overlaps with the edge projection of the bottom surface 11a1 of the first area 11b, and the first area 11b is also allowed to have a step structure connected to the bottom surface 11a1 of the first area 11b.

[0061] On the bottom surface 11a of the guide groove 11, the edge projection of the top opening 112b corresponding to the second area 11c is located within the edge projection of the bottom surface 11a2 of the second area 11c. The bottom surface 11a2 of the second area 11c and the top opening 112b are arranged opposite to each other. The bottom surface 11a1 of the first area 11b and the bottom surface 11a2 of the second area 11c constitute the bottom surface 11a of the guide groove 11.

[0062] Exemplarily, the box body 10 is made of a relatively soft metal (such as pure gold) plate, the rigidity of the metal plate is first increased by pressurization, and then the box body 10 with a predetermined groove shape is processed by CNC milling.

[0063] Exemplarily, the box body 10 is made of a relatively hard metal (such as cemented carbide) plate, and the box body 10 with a predetermined groove shape can be processed by CNC milling.

[0064] In some embodiments, see Figures 1 to 3 The lock hook 20 includes a top wall 23 and a pair of second side walls 24, and the two second side walls 24 are respectively connected to the opposite side edges of the top wall 23. Figure 4 , Figure 5 , Figure 6 In (a), when the locking hook 20 is in the locked position, the top wall 23 covers the top opening 112, and the two second side walls 24 are covered on the outside of the two first side walls 13 in a one-to-one correspondence.

[0065] The lock hook 20 having the top wall 23 and the second side wall 24 has a simple structure. The top wall 23 of the lock hook 20 covers the top opening 112 of the box body 10, so that the lock tongue 30 located in the guide groove 11 cannot be separated from the box body 10 through the top opening 112. The lock hook 20 has the function of shielding the box body 10. When the box body 10 is used as the side in contact with the body, the lock hook 20 can shield most areas of the box body 10, and the gap between the elastic member 40, the lock tongue 30 and the box body 10 cannot be seen, so that the lock buckle 100 has a better appearance effect and improves the stealthiness of the lock buckle 100.

[0066] There are multiple optional implementations when setting the elastic member 40. Three implementations of the elastic member 40 are exemplarily given below.

[0067] The first implementation method of the elastic member 40: please refer to Figure 1 , Figure 3 , Fig. 9 The elastic member 40 is in a straight line or an arc. In the first direction X, the elastic member 40 is arranged across the pivot axis 20a of the lock hook 20. The box body 10 has a mounting groove 15. One end of the elastic member 40 is installed in the mounting groove 15, and the other end of the elastic member 40 is installed in the lock hook 20.

[0068] The elastic member 40 is a straight or curved elastic member. The elastic member 40 can provide elastic force to the lock buckle 100, so that the lock buckle 100 has a tendency to switch to the locked position or keep the lock buckle 100 in the locked position, and the use cost is low. The elastic member 40 and the lock tongue 30 can be spaced a predetermined distance apart. During the bending process of the elastic member 40, the elastic member 40 is not easy to interfere with the lock tongue 30, thereby improving the reliability of the lock buckle 100.

[0069] The inner surface of the lock hook 20 may have a positioning groove 22 , and one end of the elastic member 40 may be installed in the positioning groove 22 , so as to facilitate the connection between the elastic member 40 and the lock hook 20 .

[0070] The second implementation method of the elastic member 40: please refer to Fig.10 The elastic member 40 is U-shaped, the pivot axis 20a of the lock hook 20 passes through the U-shaped opening 41 of the elastic member 40, one end of the elastic member 40 is mounted on the box body 10, and the other end of the elastic member 40 is mounted on the lock hook 20. The U-shaped elastic member 40 can provide elastic force to the lock buckle 100, so that the lock buckle 100 has a tendency to switch to the locked position or keep the lock buckle 100 in the locked position.

[0071] The third implementation method of the elastic member 40: Please refer to Fig.11 The elastic member 40 is a torsion spring, the pivot axis 20a of the lock hook 20 passes through the spiral portion 42 of the torsion spring, one end of the torsion spring is mounted on the box body 10, and the other end of the torsion spring is mounted on the lock hook 20. The torsion spring can provide elastic force to the lock buckle 100, so that the lock buckle 100 has a tendency to switch to the locked position or keep the lock buckle 100 in the locked position.

[0072] For the above three elastic members 40, in some embodiments, please refer to Figure 3 , Fig.10 , Fig.11 The number of the elastic members 40 is two, and the two elastic members 40 are distributed on opposite sides of the box body 10 in the width direction (i.e., the second direction Y). An elastic member 40 is respectively arranged on both sides of the box body 10 in the width direction, and two elastic members 40 are arranged in total, which can reduce the size of the box body 10 in the first direction X. When one of the elastic members 40 breaks, another elastic member 40 still acts on the lock hook 20, thereby improving the reliability of the lock buckle 100.

[0073] For the above three elastic members 40, in other embodiments, see Fig.12 , the number of elastic members 40 is one, and the elastic members 40 are distributed on one side of the width direction (i.e., the second direction Y) of the box body 10. A single elastic member 40 can act on the lock hook 20 to switch the lock hook 20 to the locked position. A single elastic member 40 is distributed on one side of the width direction of the box body 10, which can reduce the size of the box body 10 in the first direction X.

[0074] In some embodiments, see Figure 4 , Figure 5 The lock hook 20 has a pressing position 25 away from the top opening 112. When the bottom wall 12 of the box body 10 is in contact with the body, the lock hook 20 can cover most of the box body 10. The pressing position 25 of the lock hook 20 reminds the user that by pressing this position, the lock hook 20 can be switched from the locked position to the unlocked position. The pressing position 25 can be in the form of a groove on the lock hook 20.

[0075] In some embodiments, see Figure 1 , Figure 3 , Figure 6 The lock hook 20 can be pivotally connected to the box body 10 through a pin 50, and the pin 50 is inserted through the lock hook 20 and the box body 10. This solution enables the lock hook 20 to be rotatably connected to the box body 10, and the structure is easy to assemble.

[0076] Exemplarily, the box body 10 includes a bottom wall 12 and a first side wall 13 distributed in pairs, and the two first side walls 13 are respectively connected to the opposite two sides of the bottom wall 12. Each first side wall 13 has a first through hole 131.
