Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, and in particular to a locking component and a logistics box. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] Logistics boxes such as turnover boxes are used for the storage and transportation of goods. They can effectively prevent damage to goods during transportation, provide additional protection, and reduce losses caused by collisions, squeezing, etc. When the logistics box is being transported, the box lid needs to be locked with a lock assembly. When the goods need to be taken out, the lock assembly needs to be opened to facilitate the removal of the goods.

[0004] However, when the lock buckle and the lock hole of the lock assembly in the related art are in the open state, there is a virtual position between the lock buckle and the locking hole on the box cover, and the lock buckle still has the possibility of moving toward the locked position, thereby affecting the subsequent operation of the flow box.

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0045] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0046] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0047] In order to solve the problem that the locking part is easy to move toward the locking position after being unlocked, thereby affecting the operator's operation of the logistics box, an embodiment of the present application provides a locking part and a logistics box having the locking part, aiming to design the locking part to be able to still be limited by the card hole after being opened, so as to solve the problem that the locking part is easy to move toward the locking position after being unlocked.

[0048] The following is combined with Figure 1-16 The locking member 20 and the logistics box 100 provided in this embodiment are introduced. It should be noted that since the latch hole 11 and some structures inside the latch hole cannot be shown in the drawings, for ease of understanding, this embodiment shows the parts that cannot be shown in the form of dotted lines.

[0049] Combined with attachment Figure 1-6 As shown (the box structure is not shown in the figure, only the position of the lock hole 30 in the box is shown), this embodiment provides a locking part 20 for locking the box cover 10 and the box body of the logistics box 100. The logistics box 100 can be a turnover box used in the transportation process. The box cover 10 is approximately a plate-like structure, and the box body includes a bottom plate and a plurality of side panels connected to the bottom wall.

[0050] A latch hole 11 is provided on the upper surface of the box cover 10 adjacent to one edge. The latch hole 11 can be formed by a lock installed on the box cover 10, or the box cover 10 itself can be formed with a first protrusion 111 on one wall of the latch hole 11, or as shown in the figure, the wall of the latch hole 11 can be provided with first protrusions 111 on both sides of the wall of the latch hole 11 along the first direction X. A latch hole 30 is provided on a side panel of the box body facing the latch hole 11, and the latch hole 30 is connected to the latch hole 11. It should be noted that the above-mentioned "connected" means that the latch hole 11 and the lock hole 30 can be directly connected, or there is a certain space between them, through which the lock hole 30 and the latch hole 11 are connected.

[0051] The latch 20 can be made of a material with a certain structural strength and deformability, such as plastic. The latch 20 includes a main body 21 and a first elastic latch 22. The main body 21 and the first elastic latch 22 can be integrally injection molded or connected by a method such as heat fusion. The main body 21 can be a plate-like member as shown in the figure, or it can be a strip, block, or other shape, which are not listed one by one in this embodiment. A portion of the main body 21 of the latch 20 is inserted into the latch hole 11. The latch hole 11 functions to limit the movement of the latch 20 away from the latch hole 30 after the latch 20 is inserted into the latch hole 30.

[0052] The number of the first elastic buckles 22 corresponds to the number of the first protrusions 111 . For example, when the number of the first protrusions 111 is two as shown in the figure, the number of the first elastic buckles 22 is also two.

[0053] The first elastic buckle 22 may be connected to the main body 21 at one end and free at the other end. In addition to the portion connected to the main body 21, the remaining portion of the first elastic buckle 22 may have a gap or spacing with the main body 21 in the first direction X. When the first elastic buckle 22 is squeezed by the first protrusion 111, the remaining portion of the first elastic buckle 22, except for the end connected to the main body 21, may deform. Of course, the first elastic buckle 22 may also have a certain degree of deformation capability. In this case, the first elastic buckle 22 may not have a gap with the main body 21 (this embodiment is not shown in the figure).

[0054] The main body 21 has a first end 211 close to the lock hole 30 and a second end 212 away from the lock hole 30, and the main body 21 has two sides along the first direction X. The first elastic clip 22 is connected to the side of the main body 21 facing the first protrusion 111. The first direction X is the arrangement direction of the first elastic clip 22 to the main body 21, which can also be understood as the width direction of the main body 21 in the figure.

[0055] It should be noted that the “ends” in the first end 211 , the second end 212 , and the third end 222 and the fourth end 223 described below in this embodiment should be understood as ends with a certain length, and do not necessarily refer to end faces.

[0056] In the direction from the first end 211 to the second end 212 of the main body 21 (the second direction Y in the figure), the first elastic buckle 22 of this embodiment is sequentially provided with a first limiting portion 2211 and a second limiting portion 2212. The first elastic buckle 22 can move between a locked position and an unlocked position on the box cover 10. Figure 3 and 4As shown, when in the locked position, the first end 211 is inserted into the lock hole 30, and the second limiting portion 2212 abuts against the first protrusion 111, thereby limiting the first end 211 from being separated from the lock hole 30. At this time, the box cover 10 and the box body cannot move relative to each other.

[0057] Compared with the buckle structure in the related art, the first elastic buckle 22 configured with the first limiting portion 2211 and the second limiting portion 2212 is longer.

[0058] like Figure 5 and 6 As shown, when unlocking is required, the locking member 20 is operated to move in a direction away from the lock hole 30 (or in a direction from the first end 211 to the second end 212). At this time, the first elastic clip 22 of this embodiment is deformed, so that the part of the locking member 20 located in the card hole 11 can be at least partially separated from the card hole 11, and the first end 211 is separated from the lock hole 30. Then the locking member 20 is moved to abut against the first limiting portion 2211 and the first protrusion 111, thereby reducing the possibility of the locking member 20 moving toward the locking position, reducing or even eliminating the virtual position between the locking member 20 in the unlocked state and the card hole 11.

[0059] The first limiting portion 2211 and the second limiting portion 2212 of this embodiment have various structural forms, for example Figure 1-6 As shown in the figure, a second protrusion 221 is provided on the side of the first elastic buckle 22 facing away from the main body 21, and the second protrusion 221 has a first side 22111 facing the lock hole 30 and a second side 22121 facing away from the lock hole 30, and a third side 2213 located between the first side 22111 and the second side 22121.

[0060] In this embodiment, the first limiting portion 2211 includes a first side 22111, and the second limiting portion 2212 includes a second side 22121. In some embodiments, the first limiting portion 2211 is directly the first side 22111, and the second limiting portion 2212 is directly the second side 22121.

[0061] When the lock component 20 is in the locked state, the second side 22121 abuts against the first protrusion 111, thereby preventing the lock component 20 from moving in the direction away from the lock hole 30 and disengaging from the lock hole 30. When unlocking is required, the lock component 20 is moved in the direction of disengaging from the lock hole 30 and the card hole 11. At this time, the three sides of the second protrusion 221 are squeezed by the first protrusion 111, causing the first elastic clip 22 to deform, so that the second protrusion 221 can move from the side of the first protrusion 111 close to the lock hole 30 to the side of the second protrusion 221 away from the lock hole 30. At this time, the first side 22111 of this embodiment abuts against the first protrusion 111 to prevent the lock component 20 from moving to the locked position, reducing or even eliminating the virtual position of the lock component 20.

[0062] Similarly, when the locking member 20 needs to be moved to the locking position again, the locking member 20 is moved in the reverse direction so that the locking member 20 moves in the direction close to the card hole 11. The second protrusion 221 is squeezed by the first protrusion 111 to deform the elastic card, so that the second protrusion 221 can move from the side of the first protrusion 111 away from the lock hole 30 to the side of the second protrusion 221 close to the lock hole 30, thereby achieving locking again.

[0063] In order to facilitate the deformation of the first elastic buckle 22 and the entry and exit of the card hole 11, this embodiment designs the first side 22111 and the second side 22121 as inclined guide edges. Specifically, it can be understood that from the first end 211 to the second end 212, the distance between the first side 22111 and the main body 21 along the first direction X gradually increases, and from the first end 211 to the second end 212, the distance between the second side 22121 and the main body 21 along the first direction X gradually decreases. The first direction X is the arrangement direction of the second protrusion 221 to the main body 21.

[0064] The above structure allows the second protrusion 221 to form a structure that is approximately trapezoidal, so that when the first elastic buckle 22 is moved from the unlocked position to the locked position, the first side 22111 can form a certain guide with the first protrusion 111, facilitating the first elastic buckle 22 to enter the locking hole 11. Similarly, when the first elastic buckle 22 is moved from the locked position to the unlocked position, the second side 22121 can form a certain guide with the first protrusion 111, facilitating the first elastic buckle 22 to be released from the locking hole 11.

[0065] Combined with the attachment again Figure 1 and attached Figure 2 As shown, in some examples, optionally, the first elastic buckle 22 includes a third end 222 close to the lock hole 30 and a fourth end 223 away from the lock hole 30, and the third end 222 of the first elastic buckle 22 can be located in the hole 11 in both the locked position and the unlocked position, and the fourth end 223 is located in the hole 11 in the locked position and is detached from the hole 11 in the unlocked position.

[0066] The third end 222 is connected to the main body 21, and the connection method can be one-piece injection molding, or one-piece connection methods such as welding and hot melting. The second protrusion 221 is located between the third end 222 and the fourth end 223, and the part of the first elastic clip 22 except the third end 222 forms a gap with the side of the main body 21 facing the first protrusion 111.

[0067] When the first elastic buckle 22 moves from the unlocking position to the locking position, the first side 22111 abuts against the first protrusion 111. The first side 22111 receives pressure from the first protrusion 111, driving the first elastic buckle 22 as a whole to deform into the above-mentioned gap, thereby facilitating the first elastic buckle 22 to enter the card hole 11.

[0068] Of course, the deformation of the first elastic buckle 22 of this embodiment is not limited to the above-mentioned space avoidance through spacing, etc., and the first elastic buckle 22 itself can also have the ability to deform (this embodiment is not shown in the figure).

[0069] Based on the above-mentioned locking member 20, since the first elastic clip 22 of this embodiment needs to be configured with the above-mentioned first limiting portion 2211 and the second limiting portion 2212, its length needs to be adaptively extended compared to the locking member 20 in the related technology. Since the material of the first elastic clip 22 is generally plastic, the elasticity of the plastic material is weakened and the rigidity is increased when used at low temperatures, which will affect the first elastic clip 22 from entering and exiting the card hole 11.

[0070] Therefore, this embodiment further improves the structure of the main body 21 of the locking member 20 to facilitate the deformation of the first elastic buckle 22.

[0071] Combined with attachment Figure 7 As shown, in some examples, a relief notch 213 is optionally provided on one side of the main body 21 facing the first elastic buckle 22. The relief notch 213 is configured to accommodate at least a portion of the elastic buckle after deformation. When the main body 21 is provided with the first elastic buckle 22 on both sides along the first direction X, the number of relief notches 213 is also two.

[0072] The avoidance notch 213 can increase the distance between the first elastic buckle 22 and one side of the main body 21 , thereby making it easier for the first elastic buckle 22 to deform under the pressure of the first protrusion 111 .

[0073] In some examples, optionally, along the direction from the third end 222 to the fourth end 223 , the size of the avoidance gap 213 along the first direction X gradually increases.

[0074] The above structure enables the avoidance gap 213 to form a structure that gradually increases in size from the third end 222 to the fourth end 223. The reason for this structural design is that the second protrusion 221 is closer to the fourth end 223 than the third end 222, and when the first elastic clip 22 is deformed, the deformation displacement of the part that is further away from the third end 222 is greater. Therefore, the avoidance gap 213 is designed to be along the direction from the third end 222 to the fourth end 223, and the size of the avoidance gap 213 along the first direction X gradually increases, so that it can better match the displacement of the deformation of each part of the first elastic clip 22.

[0075] Combined with attachment Figure 8-12 As shown, the embodiment of the present application further provides another locking member 20. In the locking member 20, the first elastic buckle 22 of this embodiment is not an integral structure, but is constructed as a split structure.

[0076] In some examples, optionally, the first elastic buckle 22 includes a first sub-buckle 224 and a second sub-buckle 225. From the first end 211 to the second end 212, the first sub-buckle 224 and the second sub-buckle 225 are spaced apart. The end of the first sub-buckle 224 facing away from the second sub-buckle 225 is connected to the main body 21. The connection method can be one-piece molding or one-piece connection.

[0077] The second sub-clip 225 is connected to the main body 21 at the end facing away from the first sub-clip 224. The connection can be integrally formed or integrally connected. A first stopper 2211 is provided on the side of the first sub-clip 224 facing away from the main body 21, and a second stopper 2212 is provided on the side of the second sub-clip 225 facing away from the main body 21.

[0078] In some examples, optionally, the first limiting portion 2211 includes a third protrusion 2241 arranged on the side of the first sub-clip 224 away from the main body 21, and the second limiting portion 2212 includes a fourth protrusion 2251 arranged on the side of the first sub-clip 224 away from the main body 21.

[0079] Combined with attachment Figure 9 and 10 As shown, when the locking member 20 is in the locked position, the second sub-clip 225 and the first sub-clip 224 are both located in the card hole 11, and the fourth protrusion 2251 on the second sub-clip 225 is limitedly engaged with the first protrusion 111 to prevent the locking member 20 from falling out of the card hole 11.

[0080] Combined with attachment Figure 11 and 12 As shown, when unlocking is required, the locking member 20 is operated to move so that the second sub-clip 225 is disengaged from the card hole 11, and then the third protrusion 2241 of the first sub-clip 224 is disengaged from the card hole 11 and abuts against the first protrusion 111, thereby reducing the possibility of the locking member 20 being in a vacant position.

[0081] The advantage of designing the first elastic buckle 22 to include a separate first sub-buckle 224 and a second sub-buckle 225 is that the first sub-buckle 224 and the second sub-buckle 225 are shorter in length and can be deformed separately, making it easier to enter or exit the buckle hole 11 under deformation.

[0082] Combined with attachment Figure 3 、 5 , 9, 11 and 13, based on the above-mentioned locking member 20, this embodiment also provides a logistics box 100, including a box body (only the lock hole 30 on the box body is shown in the figure), a box cover 10 and the above-mentioned locking member 20.

[0083] The box body may include a bottom wall and side walls connected to the bottom wall, wherein the side wall on one side is provided with the above-mentioned lock hole 30, the bottom wall and the side walls surround a receiving groove, and the receiving groove and the box cover 10 surround a receiving cavity.

[0084] A locking hole 11 and a slide groove 12 communicating with the locking hole 11 are provided on the box cover 10. Accordingly, a portion of the locking member 20 of this embodiment is inserted into the locking hole 11, and the other portion is located in the slide groove 12, so that the operator can operate the portion of the locking member 20 located in the slide groove 12 to make the locking member 20 slide along the extension direction of the slide groove 12, thereby realizing the movement of the locking member 20 between the locking position and the unlocking position.

[0085] Furthermore, in order to facilitate the sliding of the locking member 20 in the slide groove 12, a handle 2121 located in the slide groove 12 can be provided at the second end 212, and a pressing groove 21211 is provided on the side of the handle 2121 facing away from the bottom wall of the slide groove 12. The operator's fingers can be inserted into the pressing groove 21211 and press against the side walls and bottom walls of the pressing groove 21211, thereby facilitating the sliding of the locking member 20.

[0086] Combined with attachment Figure 13-16 As shown, in some examples, optionally, a guide hole 13 is provided on the hole wall of the clamping hole 11. The guide hole 13 is a long through hole structure, and of course it can also be a blind hole.

[0087] Correspondingly, a second elastic clip 23 is provided on the main body 21 of this embodiment, and the locking member 20 moves from the locking position to the unlocking position. The second elastic clip 23 is configured to be able to move into the guide hole 13 and slide along the guide hole 13, so that the stability of the locking member 20 sliding in the slide groove 12 can be improved through the cooperation between the second elastic clip 23 and the guide hole 13.

[0088] In some examples, optionally, a fifth protrusion 14 is provided on the hole wall of the latch hole 11. When the locking member 20 is in the locked position, the fifth protrusion 14 abuts against the second elastic latch 23. The guide hole 13 can be used to limit the locking member 20 from continuing to move away from the locking hole 30 after the locking position, thereby further improving the stability of the locking member 20 in the locked state.

[0089] The second elastic clip 23 of this embodiment can have various structural forms. For example, as shown in the figure, a through hole is formed in the main body 21, and the second elastic clip 23 is integrally connected to or integrally formed with a hole wall of the through hole. The cross-sectional dimensions of the second elastic clip 23 are smaller than the dimensions of the through hole. The second elastic clip 23 can be at least partially accommodated in the through hole under the pressure of the fifth protrusion 14. Of course, the through hole can be replaced by a pressing groove 21211.

[0090] Alternatively, the second elastic buckle 23 can be directly connected to the upper surface of the main body 21 (this structure is not shown in the figure). When the lock member 20 moves to the unlocked position, the fifth protrusion 14 applies pressure to the second elastic buckle 23, and the second elastic buckle 23 deforms to contact the stopper of the fifth protrusion 14 and then slides into the guide hole 13. In this structure, a portion of the second elastic buckle 23 can also be spaced apart from the main body 21, thereby facilitating the deformation of the second elastic buckle 23.

[0091] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
