Description

Technical Field

[0001] This utility model relates to locks, and more specifically, to a locking structure and a box having the locking structure. Background Technology

[0002] Locks come in various types, including: mechanical locks that are opened using a key and lock cylinder; combination locks that have a password verification system; and latches that do not require a key or password, only manual locking or unlocking. These latches are typically installed on boxes or other containers that need temporary locking, such as chess sets. Once locked, the latch is only to prevent other items inside the container from falling out; when needed, the latch can be easily opened and the items retrieved without a key or password.

[0003] A typical chess box includes an upper lid and a lower lid, which are rotatably connected. When the upper and lower lids are fastened together, a space is formed between them to hold the chess pieces. When fastened, an upper latching component on the upper lid and a lower latching component on the lower lid engage to lock the lids in place. However, a unique feature of this chess box is the chessboard markings on the back of the upper and lower lids, specifically on the opposite outer sides of the upper and lower lids where the space is located. When the upper and lower lids are opened and folded completely, the chessboard markings on the lids align to form a complete chessboard. The chessboard indicates the rules of the game, and users play chess using pieces taken from the space. However, when the top and bottom covers are opened and folded, gaps will form at the connection point because the top and bottom covers are connected. In other words, there will be a certain angle between the top and bottom covers, making it uneven. An uneven chessboard obviously cannot meet the needs of playing chess.

[0004] Therefore, the technical problem to be solved in this application is how to design a locking and unlocking structure that is convenient for locking and unlocking, and apply it to the box body so that the upper and lower covers of the box body can be folded flat after the box body is opened. Utility Model Content

[0005] The purpose of this utility model is to provide a locking structure.

[0006] The locking structure disclosed in this utility model includes:

[0007] A first locking component is installed at one end of the box body; the first locking component includes a first fixed base and a fastening member rotatably connected to the first fixed base, the fastening member having a locking space on the side facing the first fixed base; the fastening member rotates relative to the first fixed base from its rotational position to move closer to or further away from the first fixed base, thereby achieving locking or unlocking.

[0008] The second locking component includes a second fixing base and a deformable locking mechanism mounted on the second fixing base. The locking mechanism is located on the second fixing base away from the surface of the first fixing base, and the second fixing base is mounted on the other end of the box.

[0009] The first fixing base has a first protrusion and a first receiving portion on its surface facing the second fixing base; the second fixing base has a second protrusion and a second receiving portion on its surface facing the first fixing base.

[0010] When the locking structure is in the locked state, the first fixing base and the second fixing base are opposite to each other and the first protrusion is located in the second receiving portion, and the second protrusion is located in the first receiving portion. The first fixing base and the second fixing base are simultaneously embedded into the locking space. When the locking structure is in the locked state, the locking mechanism presses against the side wall of the locking space to adapt to the engagement fastener and prevent the first fixing base and the second fixing base from separating from each other.

[0011] When the fastening element rotates away from the second fixing base, the second fixing base disengages from the first fixing base, thereby making the locking structure in the unlocked state;

[0012] When the locking structure is in the unlocked state, the first protrusion and the second protrusion act as support feet to support the box body.

[0013] This application also discloses a housing, the housing comprising:

[0014] The upper cover and the lower cover are rotatably connected, thereby allowing the box to open and close; when the box is closed, the contact surfaces of the upper cover and the lower cover are end faces, and the surfaces of the upper cover and the lower cover relative to the hinge are vertical surfaces;

[0015] At least two locking structures are provided, each of which includes a first locking component and a second locking component. The first locking component is mounted on the vertical surface of the upper cover, and the second locking component is mounted on the vertical surface of the lower cover. The first locking component and the second locking component are opposite to each other.

[0016] When the locking structure is in the unlocked state, the first protrusion and the second protrusion protrude from the end face and serve as support feet to support the box body.

[0017] This utility model discloses a locking structure and a box body with the locking structure. The locking structure allows for easy insertion of a first fixed base and a second fixed base through a first protrusion and a second protrusion. A fastening member simultaneously accommodates and locks the first and second fixed bases within the locking space of the fastening member, thus achieving locking. When the fastening member is rotated and disengaged from the second fixed base, the second fixed base detaches from the first fixed base, thus achieving unlocking. When the first and second fixed bases are respectively installed near the two end faces of the box body that need to be locked, the first and second protrusions can also be used as supporting legs for the box body after it is opened, thereby ensuring the flatness of the spliced ​​surface after the box body is folded. The locking structure of this application is simple in overall structure, easy to operate, and the box body is aesthetically pleasing and cost-effective. Attached Figure Description

[0022] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0023] See Figure 1 and Figure 2 The box 100 includes an upper cover 11 and a lower cover 12. The upper cover 11 and the lower cover 12 are rotatably connected, thereby allowing the box 100 to open and close. Here, the box 100 is exemplified as a chess box.

[0024] When the upper cover 11 and the lower cover 12 are closed, they form a sealed cavity 13 for containing items. After the box 100 is closed, the contact surfaces of the upper cover 11 and the lower cover 12 are end faces 14, and the surfaces of the upper cover 11 and the lower cover 12 relative to the hinge are vertical faces 15. When the box 100 is opened and flipped, the outer surfaces of the upper cover 11 and the lower cover 12 fold together to form a relatively flat plane. Patterns or lines can be set on the outer surfaces of the upper cover 11 and the lower cover 12 to create a chessboard for playing chess.

[0025] When the upper cover 11 and the lower cover 12 are folded over, the end faces 14 of the upper cover 11 and the lower cover 12 are placed downwards, and can be placed on a table or the ground.

[0026] The box body 100 is also provided with at least two locking structures 200, and the two locking structures 200 are respectively located near the two sides of the box body 100.

[0027] The locking structure 200 has at least two components, which are distributed in pairs on both sides of the box body. Each locking structure 200 includes a first locking component 21 and a second locking component 22. The first locking component 21 is mounted on the vertical surface 15 of the upper cover 11, and the second locking component 22 is mounted on the vertical surface 15 of the lower cover 12, with the first locking component 21 and the second locking component 22 facing each other.

[0028] like Figure 2 The first locking component 21 includes a first fixed base 210 and a fastening member 211 rotatably connected to the first fixed base 210. The fastening member 211 has a locking space 212 on the side facing the first fixed base 210. The fastening member 211 rotates relative to the first fixed base 210 to move closer to or further away from the first fixed base 210, thereby locking or unlocking. The first fixed base 210 is mounted on the vertical surface 15.

[0029] The second locking component 22 includes a second fixing base 220 and a deformable locking mechanism 221 mounted on the second fixing base 220. The locking mechanism 221 is located on the second fixing base 220, away from the surface of the first fixing base 210, namely the vertical surface 15.

[0030] The first fixing base 210 has a first protrusion a1 and a first receiving portion b1 on the surface facing the second fixing base 220; the second fixing base 220 has a second protrusion a2 and a second receiving portion b2 on the surface facing the first fixing base 210.

[0031] When the upper cover 11 and the lower cover 12 are closed and the locking structure 100 is in the locked state, the first fixing base 210 and the second fixing base 220 are opposite to each other and the first protrusion a1 is located in the second receiving portion b2, and the second protrusion a2 is located in the first receiving portion b1. The first fixing base 210 and the second fixing base 220 are simultaneously embedded in the locking space 212. When the locking state is reached, the locking mechanism 221 is pressed against the side wall of the locking space 212 to adapt to the engagement fastener 211 and prevent the first fixing base 210 and the second fixing base 220 from disengaging from each other.

[0032] When the fastening member 211 rotates away from the second fixing base 220, the second fixing base 220 disengages from the first fixing base 210, thereby making the locking structure 200 in an unlocked state.

[0033] like Figure 3 When the locking structure 200 is in the unlocked state and the box body 100 is folded into a relatively flat plane, after the upper cover 11 and the lower cover 12 are assembled to form a chessboard, the first protrusion a1 and the second protrusion a2 protrude from the end face 14 and serve as supporting feet on the table or ground to support the box body 100. At this time, the first protrusion a1 and the second protrusion a2 are in the same plane. Due to gravity, the upper cover 11 and the lower cover 12 will press down at the hinge position and abut against each other, thereby forming a flat plane without gaps, making the appearance more beautiful.

[0034] Among them, such as Figure 2 and 3 The two latching structures 200 located on both sides of the box body 100 form two first protrusions a1 and two second protrusions a2 when opened, for a total of four support legs. At this time, the two first protrusions a1 and the two second protrusions a2 form the four vertices of a quadrilateral, making the box body 100 more securely fixed.

[0035] like Figure 2 and Figure 4 The position of the first protrusion a1 is opposite to the position of the second receiving part b2, and the position of the second protrusion a2 is opposite to the position of the first receiving part b2; the first protrusion a1 and the second protrusion a2 have the same length; the first receiving part a1 and the second receiving part a2 with the same length can ensure that the box body 100 does not tilt when used as a support foot.

[0036] In this application, the size of the first receiving portion b1 is larger than the size of the second protrusion a2; the size of the second receiving portion b2 is larger than the size of the first protrusion a1. Only when the first fixing base 210 and the second fixing base 220 are aligned with each other in the length direction and inserted can the locking member 210 be rotated to simultaneously accommodate both the first fixing base 210 and the second fixing base 220 within its locking space 212, thus achieving locking. Therefore, when the size of the first receiving portion b1 is larger than the second protrusion a2, the insertion of the first fixing base 210 and the second fixing base 220 can be easily achieved without encountering problems with accurate alignment and insertion due to small size differences. The size difference between the first receiving portion b1 and the second protrusion a2 only needs to ensure that, when the locking member 210 is locked, the first fixing base 210 and the second fixing base 220 cannot be separated in the thickness and width directions. When the box body 100 is made of rigid material, when the first fixing base 210 and the second fixing base 220 are installed on the rigid material, neither the first fixing base 210 nor the second fixing base 220 can move in the thickness direction. Therefore, the dimensions of the first receiving part b1 and the second protrusion a2, which are easy to insert, only need to ensure that they are not separated in the width direction.

[0037] In this application, the first protrusion a1 and the second protrusion a2 are columnar nails, and the first receiving portion b1 and the second receiving portion b2 are receiving holes. The purpose of positioning by aligning the nails and holes is achieved, facilitating the insertion of the first and second fixing bases, especially when the receiving hole is a slot, which further facilitates the insertion of the first and second fixing bases. Figure 4 , Figure 4 This is a split diagram of the locking structure 100 of this utility model.

[0038] In addition to the first fixed base 210, the first locking component 21 also includes a first mounting base 213, and the first fixed base 210 is mounted on the vertical surface 15 through the first mounting base 213.

[0039] In this invention, the width of the first mounting base 213 is greater than that of the first fixing base 210, meaning that the first mounting base 213 protrudes from the first fixing base 210. One possible configuration is that the first mounting base 213 and the first fixing base 210 are integrally formed, with the first mounting base 213 extending from the first fixing base 210; the thickness of the first mounting base 213 is less than that of the first fixing base 210; mounting holes 214 are provided on the first mounting base 213, and the first mounting base 213 is fixed to the vertical surface 15 through the mounting holes 214, thereby fixing the first fixing base 210 to the box body 100.

[0040] The locking mechanism 221 is elastic and protrudes from the surface of the second fixing base 220.

[0041] Similarly, the second locking component 22 also includes a second mounting base 222, through which the second fixing base 220 is mounted to the vertical surface 15. The width of the second mounting base 222 is greater than that of the second fixing base 220, meaning that the second mounting base 223 protrudes from the second fixing base 220. One possible configuration is that the second mounting base 222 and the second fixing base 220 are integrally formed, with the second mounting base 222 extending from the first fixing base 220; the thickness of the second mounting base 222 is less than that of the second fixing base 220, and mounting holes 223 are provided on the second mounting base 222. The second mounting base 222 is fixed to the vertical surface 15 through the mounting holes 223, thereby fixing the second fixing base 220 to the box body 100.

[0042] In this application, the width of the first mounting base 213 is equal to the width of the second mounting base 222; simultaneously, the widths of both the first mounting base 213 and the second mounting base 222 are equal to the width of the fastening member 211, thereby causing the fastening member 211 to cover the first fixing base 210 and the first mounting base 213, as well as the second fixing base 220 and the second mounting base 222, when locked. At this time, when the fastening member 211 is locked, it completely closes the first mounting base 213 and the second mounting base 222, and even simultaneously accommodates the first fixing base 210 and the second fixing base 220 within the locking space 212. The widths of the first fixing base 210 and the second fixing base 220 are not greater than the width of the locking space 212 to facilitate their accommodation.

[0043] Specifically, the width of the first fixing base 210 and the width of the second fixing base 220 are equal to the width of the locking space 212. At this time, the first fixing base 210 and the second fixing base 220 are both firmly fixed in the locking space 212 to prevent the first fixing base 210 and the second fixing base 220 from shaking in the width direction of the locking space 212.

[0044] In this application, after the first fixing base 210 and the fastening member 211 are rotatably connected, they have a wobbling gap. That is, when the fastening member 211 rotates relative to the first fixing base 210 or the second fixing base 220 for locking, the structure composed of the first fixing base 210 and the second fixing base 220 can wobble within a small range relative to the fastening member 211, thereby adjusting the angle and distance at which it is accommodated in the locking space 212, thus avoiding the problem of the second fixing base 220 being difficult to accommodate in the locking space 212. The maximum wobbling distance is less than the maximum length of the locking mechanism 221.

[0045] In one embodiment of the present invention, the length of the first fixing base 210 is set to 1.8 cm, and the length of the second fixing base 220 is the same as the length of the first fixing base 210; however, the length of the locking mechanism 221 protruding from the surface of the second fixing base 220 is set to 2.1 mm, and the total length after the first fixing base 210 and the second fixing base 220 are inserted is 1.8 + 1.8 + 0.21 = 3.81 cm; at this time, the length of the locking space 212 for accommodating the first fixing base 210 and the second fixing base 220 is set to 3.60 cm; When the first fixed base 210 and the second fixed base 220 are connected, during the rotation of the fastening member 211 relative to the first fixed base 210, the inner wall of the fastening member 211, that is, the inner wall of the locking space 212, comes into contact with the locking mechanism 221. When fastening, by shaking the first fixed base 210 and the second fixed base 220 relative to each other, the allowance of the locking mechanism 221 extending beyond the inner wall of the fastening member 211 can be reduced. Under the action of external force, the fastening member 211 is pressed down, and the external force can press the second fixed base 220 and the locking mechanism 221 into the locking space 212. At this time, the deformable locking mechanism 221 deforms towards the inside of the locking space 212 when it is pressed into the locking space 212. After the locking mechanism 221 is pressed into the locking space 212, the locking mechanism 212 returns to its original shape and presses against the inner wall of the fastening member 211. In this application, the swaying gap can be selected between 1.8mm and 2.1mm, with 2mm being preferred. When the swaying gap is 2mm, the allowance of the locking mechanism 221 extending beyond the inner wall of the fastening member 211 is reduced to 0.1mm when no pressure is applied, which can conveniently and quickly realize the fastening of the locking mechanism 211 and lock the second fixing base 220 in the locking space 212 after fastening.

[0046] From another perspective, the length x3 of the locking mechanism 221 is greater than 2mm. This means that even if the second fixed base 220 rotates the fastening member 211 to lock with the maximum rotation radius, it can still ensure that the inner wall of the locking space 212 is in contact with the locking mechanism 221. The deformation of the locking mechanism 221 is used to press and fix the second fixed base 220, thereby preventing the fastening member 211 from separating from the second fixed base 220 without external force, thus preventing accidental unlocking.

[0047] The first fixing base 210 has through holes 215 on both sides in the width direction, and the fastening member 211 has a pair of rotating holes 216 on the inner wall of the locking space 212. The rotating shaft c passes through the two through holes 215 and is fixedly installed in the rotating holes 216. The fastening member 211 rotates relative to the first fixing base 210 with the rotating shaft c. The diameter of the through hole 215 is larger than that of the rotating shaft c. In this application, when the fastening member 211 rotates, the rotation center axis, i.e., the rotating shaft c, can oscillate within the through hole 215, thereby changing the rotation radius during the rotation process. This allows the inner wall of the locking space 212, away from the rotating shaft c, to contact the mounting surface where the locking mechanism 221 is located, thus first accommodating the distal end of the second fixing base 220 into the locking space 212. Then, the fastening member 211 continues to press down, at which point the inner wall of the locking space 212, away from the rotating shaft c, contacts the locking mechanism 221. The locking mechanism 221 deforms under the action of the fastening member 211 until the locking mechanism 221 and the second fixing base 220 are completely accommodated within the locking space 212, at which point locking is completed.

[0048] The locking space 212 has a locking hole 217 on its inner wall, which is positioned opposite to the first fixing base 210. When locked, the locking hole 217 accommodates the locking mechanism 221, which is an elastic pin. After the locking mechanism 221 is fixed within the locking hole 217, its deformation can press against the first fixing base 210 and the second fixing base 220, minimizing movement. Furthermore, the locking hole 217 can also serve as a fixing point to position and fix the second fixing base 220 within the locking space 212, further reducing movement between the first fixing base 210 and the second fixing base 220. In this application, the length of the locking space 212 is Y, the length of the first fixing base 210 is X1, the length of the second fixing base 220 is X2, and the length of the locking mechanism 221 protruding from the surface of the second fixing base 220 is X3; then: X1+X2+X3>Y≥X1+X2.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
