[0002] This application claims priority from a Chinese patent application filed on 12.10.22, application number 2022112457366, for the invention entitled "Container," the entire text of which is incorporated herein by reference.

[0003] The present invention relates to the field of containers, and in particular to containers. [Background technology]

[0004] Existing storage containers, particularly those that require cargo to be sealed, generally have a box lid, which is closed after the cargo is loaded into the container to prevent the cargo from being affected by the environment outside the box, resulting in moisture, deterioration, contamination, etc., during transportation and rotation. To increase the stability of the box body and box lid and prevent the box lid from separating from the box body due to shaking during transportation and rotation, a connecting structure between the box lid and the housing, such as a lock, hinge, or elastic hook, is added. However, these connecting parts are usually attached to the box body and box lid, respectively, using fasteners such as rivets or screws to achieve the connection and lock between the box body and box lid. However, this requires many mounting parts, a complex process, and high installation requirements, making it unsuitable for mass production. Furthermore, after the container is locked, it is easy to accidentally touch the connecting structure, which could cause the box lid to separate from the box body. Summary of the Invention

[0005] To provide a container which requires fewer parts for attaching a locking device, is easy to mass-produce by simple processes, and can prevent the box body and the box lid from being separated due to accidental contact.

[0006] In order to solve the above technical problems, an embodiment of the present invention provides a container, the container comprising: The box itself and a box lid for opening and closing the box body; a locking device including a locking member, a resetting member, and a control member, wherein the locking member is hingedly connected to one of the box body or the box lid, the control member is movably connected to the locking member, one end of the resetting member abuts against the locking member, and the other end of the resetting member abuts against the control member, the control member includes a locking tongue, and the resetting member applies an abutting force to the locking tongue; The locking member is used to drive the resetting member and the control member so that the resetting member and the control member are reversed around the hinge portion of either the locking member or the box body or the box lid, and when the locking member reverses the control member to a preset position, the locking tongue operably locks the other of the box body or the box lid by the abutting force of the resetting member.

[0007]

[0013] Compared with the prior art, the embodiment of the present invention has a container locking device attached to the container, in which a locking member is hingedly connected to one of the box body or the box lid via a hinge shaft, the hinge shaft rotates the locking member, and both ends of the reset member abut against the control member and the locking member, respectively. When the locking member rotates around the hinge shaft, the control member also rotates as the locking member rotates, and when the control member rotates to the other of the box body or the box lid and locks it, the container is locked. When it is necessary to separate the box body and the box lid, the control member must first be moved away from the interlocking position with the other of the box body or the box lid, and then the locking member must be rotated around the hinge shaft in order to separate the box body and the box lid. Otherwise, simply moving the control member away from the interlocking position with the other of the box body or the box lid will not separate the box body and the box lid. This prevents the box body and the box lid from being separated by accidentally touching the control member or colliding with the control member due to a collision. Therefore, a container equipped with this locking device is safer during use and will not separate the box lid and box body due to accidental contact, resulting in unlocking. In addition, the container locking device according to the embodiment of the present invention has few parts, a simple structure, and is easy to install, which is advantageous for mass production and also prevents the box body and box lid from separating due to accidental contact.

[0029] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0030] An embodiment of the present invention provides a container 10 including a box body 100, a box lid 200, and a locking device 300. The box lid 200 is used to open and close the box body 100. The locking device 300 includes a locking member, a resetting member, and a control member. The locking member is hingedly connected to the box body 100, and the control member is movably connected to the locking member, with one end of the resetting member abutting the locking member and the other end abutting the control member. The control member includes a locking tongue, and the resetting member applies an abutting force to the locking tongue. The locking member is used to rotate the resetting member and the control member around the hinge portion between the locking member and the box body 100. When the locking member rotates the control member to a predetermined position, the abutting force of the resetting member causes the locking tongue to operably lock the box lid 200.

[0031] The locking device 300 for the container 10 of the embodiment of the present invention is attached to the container 10, and the locking member is hingedly connected to one of the box body 100 or the box lid 200 via a hinge shaft, the hinge shaft rotates the locking member, and both ends of the reset member abut against the control member and the locking member, respectively, and when the locking member rotates around the hinge shaft, the control member also rotates in conjunction with the rotation of the locking member, and when the control member rotates to the other of the box body 100 or the box lid 200 and locks it, the container 10 is locked. When it is necessary to separate the box body 100 and the box lid 200, the control member must first be released from the interlocking position with either the box body 100 or the box lid 200, and then the locking member must be rotated about the hinge axis in order to separate the box body 100 and the box lid 200; otherwise, simply releasing the control member from the interlocking position with either the box body 100 or the box lid 200 will prevent the box body 100 and the box lid 200 from separating. This prevents the box body 100 and the box lid 200 from being separated due to accidental contact with the control member or collision with the control member. The locking device 300 for a container 10 according to an embodiment of the present invention has few parts, a simple structure, and is easy to install, which is advantageous for mass production and also prevents the box body 100 and the box lid 200 from being separated due to accidental contact.

[0032] In the embodiment of the present invention, an example has been shown in which the locking member is hingedly connected to the box body 100, the locking member rotates the reset member and the control member around the hinge portion of the locking member and the box body 100, and when the locking member rotates the control member to a preset position, the locking tongue locks the box lid 200 so that it can be operated by the abutting force of the reset member. However, in another embodiment, the locking member is hingedly connected to the box lid 200, the locking member rotates the reset member and the control member around the hinge portion of the locking member and the box lid 200, and when the locking member rotates the control member to a preset position, the locking tongue locks the box 100 so that it can be operated by the abutting force of the reset member. It should be understood that such an embodiment does not depart from the scope of the present invention and can be installed according to actual needs by a person skilled in the art.

[0033] The scope of the present invention will be specifically explained below by dividing it into two examples.

[0034] Example 1 As shown in FIG. 1, the container 10 includes a box body 100, a box lid 200, and a locking device 300. The box lid 200 is used to open and close the box body 100. As shown in FIG. 2, the locking device 300 includes a locking member 31, a resetting member 32, and a control member 33. The locking member 31 is hingedly connected to the box body 100, and the control member 33 is movably connected to the locking member 31. One end of the resetting member 32 abuts against the locking member 31, and the other end of the resetting member 32 abuts against the control member 33. The control member 33 includes a locking tongue 331, and the resetting member 32 applies a contact force to the locking tongue 331. The locking member 31 is used to rotate the resetting member 32 and the control member 33 around the hinge portion between the locking member 31 and the box body 100. As shown in FIG. 3 , when the locking member 31 flips the control member 33 to a preset position, the locking tongue 331 operably locks the box cover 200 due to the contact force of the reset member 32. Specifically, as shown in FIG. 7 , which is an enlarged partial view of B in FIG. 6 , the locking member 31 includes a locking body 311 and a hinge shaft 312 provided at the end of the locking body 311, with the locking tongue 331 facing the hinge shaft 312. The box cover 200 is provided with a protruding stopper portion 21, and the locking body 311 has a through-hole 3111. When the locking member 31 is flipped to a preset position, the stopper portion 21 and the locking tongue 331 operably engage with each other, pass through the through-hole 3111, and are locked together. Those skilled in the art can install the stopper portion 21 according to actual needs. It should be understood that in an embodiment in which the locking member 31 is hingedly connected to the box cover 200, the stopper portion 21 is provided on the box body 100. Preferably, when the locking member 31 is flipped to a preset position, i.e., the position shown in FIG. 3, the stopper portion 21 passes through the through hole 3111, and the locking tongue 331 is operably locked to the stopper portion 21. Those skilled in the art can set it according to actual needs. It should be understood that, without departing from the scope of the present invention, when the locking member 31 is flipped to the preset position, the locking tongue 331 passes through the through hole 3111, and the locking tongue 331 is operably locked to the stopper portion 21.

[0035] 3, the locking member 31 is hingedly connected to the box body 100, the stopper portion 21 is installed on the top of the box lid 200, the locking body 311 has a first mounting surface 3112 and a second mounting surface 3113 installed opposite the first mounting surface 3112, and the locking tongue 331 is located on the side where the second mounting surface 3113 is located. As shown in FIG. 2, a portion of the second mounting surface 3113 is bent and extended toward the side where the first mounting surface 3112 is located to form a receiving portion 3114, which abuts against the top of the box lid 200 when the locking member 31 is flipped to a predetermined position. When the receiving portion 3114 abuts against the top of the box lid 200, the box body 100 and the box lid 200 are tightly attached to each other when the locking device 300 locks the container 10. It should be understood that in the embodiment in which the locking member 31 is hingedly connected to the box lid 200, the stopper portion 21 is provided on the box body 100, and when the locking member 31 is flipped to a preset position, the receiving portion 3114 abuts against the box body 100.

[0036] As shown in Fig. 1, the side on which the locking device is attached is the locking side, and the stopper portion 21 is a plate extending toward the locking side as shown in Fig. 3, with the end of this plate toward the locking side bent upward to form a hook body, and the locking tongue abuts against this hook body to form a locking device that locks the cover plate. In another embodiment, it is understood that the stopper portion is formed by carving a groove in the cover plate, and the locking tongue enters the groove and abuts against the side wall of the groove to form a lock. Alternatively, the locking tongue may be a locking hook, and the stopper portion 21 is a hole, with the locking hook being hooked into the hole to form a locking device that locks the cover plate.

[0037] 3, the control member 33 further includes a button 332 fixedly connected to the locking tongue 331. The button 332 is hingedly connected to the locking member 31, and the other end of the reset member 32 abuts against the button 332. The reset member 32 operably rotates around the hinge portion between the button 332 and the locking member 31, applying a contact force to the button 332 to move the locking tongue 331 toward the through-hole 3111. When it is necessary to lock the container 10, the hinge shaft 312 rotates the locking member 31, and both ends of the reset member 32 abut against the button 332 and the locking member 31, respectively. When the locking member 31 rotates around the hinge shaft 312, the button 332 and the locking tongue 331 also rotate in conjunction with the rotation of the locking member 31. The locking tongue 331 rotates until the stopper portion 21 of the box lid 200 is locked, thereby locking the container 10. The operation of opening the container 10 is the reverse of the above procedure, and the process of opening the container 10 is shown with reference to Figures 4 and 5. Those skilled in the art can set it up according to actual needs.

[0038] 3, the button 332 is preferably provided with a protruding connecting shaft 3321, which is hingedly connected to the locking member 31. The resetting member 32 has a torsion spring portion 321 fitted onto the connecting shaft 3321, and a first connecting portion 322 and a second connecting portion 323 extending from both ends of the torsion spring portion 321, with the first connecting portion 322 abutting against the button 332 and the second connecting portion 323 abutting against the locking member 31. Those skilled in the art can design these portions according to actual needs. In addition to the above-described structure, the resetting member 32 may have another elastic structure, such as an elastic piece.

[0039] Furthermore, when the locking member 31 is reversed to the preset position, the first connecting portion 322 pushes and rotates the locking tongue 331 until the locking tongue 331 abuts against the stopper portion 21. Those skilled in the art can set it according to actual needs.

[0040] Example 2 As shown in Fig. 8, the container 10 includes a box body 100, a box lid 200, and a locking device 300. The box lid 200 is used to open and close the box body 100. As shown in Fig. 9, the locking device 300 includes a locking member 41, a resetting member 42, and a control member 43. The locking member 41 is hingedly connected to the box body 100, and the control member 43 is movably connected to the locking member 41. One end of the resetting member 42 abuts against the locking member 41, and the other end of the resetting member 42 abuts against the control member 43. The control member 43 includes a locking tongue 431, and the resetting member 42 applies a contact force to the locking tongue 431. The locking member 41 is used to rotate the resetting member 42 and the control member 43 around the hinge portion between the locking member 41 and the box body 100. As shown in FIG. 10, when the locking member 41 reverses the control member 43 to a preset position, the locking tongue 431 locks the box lid 200 so that it can be operated by the contact force of the resetting member 42.

[0041] Specifically, as shown in FIG. 10 , the locking tongue 431 is movably mounted on the locking member 41, and the other end of the resetting member 42 abuts against the locking tongue 431, exerting a contact force that moves the locking tongue 431 toward the end away from the resetting member 42. The control member 43 further includes a button 432 movably connected to the locking member 41. The button 432 abuts against the locking tongue 431 and is movably mounted thereon. When the resetting member 42 presses and moves the locking tongue 431, the locking tongue 431 presses and moves the button 432 in a direction perpendicular to the direction of movement of the locking tongue 431. When locking the container 10, the locking member 41 is rotated, causing the locking member 41 to flip the resetting member 42 and the control member 43 around the hinge portion between the locking member 41 and the box body 100. When the locking member 41 flips the control member 43 to a preset position, the locking tongue 431 operably locks the box lid 200 by the abutting force of the resetting member 42. When no external force is applied, the resetting member 42 is in a relaxed state, allowing the locking tongue 431 to maintain the lock of the box lid 200 when no external force is applied. When it is necessary to open the box lid 200, the button 432 is pressed by hand, and the button 432 pushes the locking tongue 431 away from the box lid 200, compressing the resetting member 42. Thereafter, the locking member 41 needs to be flipped along the hinge portion between the locking member 41 and the box body 100 so that the locking member 41 moves away from the box lid 200. The above embodiment hinges the locking member 41 to the box body 100, and it is understood that those skilled in the art can also hinge the locking member 41 to the box cover 200 according to actual needs.

[0042] Preferably, as shown in FIG. 9 , the locking member 41 has an attachment groove 412, which has a pair of first groove side walls 4121 spaced apart from each other, a second groove side wall 4122 connected to the pair of first groove side walls 4121, and a groove bottom 4123 connecting the pair of first groove side walls 4121 and the second groove side wall 4122, the second groove side wall 4122 being located on the side of the attachment groove 412 away from the side where the locking member 41 and the box body 100 are hingedly connected, and the pair of first groove side walls 4121 and second groove side walls 4122 surround the groove bottom 4123. A locking tongue 431 is slidably connected to the pair of first groove side walls 4121, one end of the resetting member 42 abuts against the second groove side wall 4122, and the other end of the resetting member 42 abuts against one end of the locking tongue 431 facing the second groove side wall 4122. As shown in FIG. 10 , a button 432 is slidably connected to the pair of second groove side walls 4122, and has a guide surface 4321 that abuts against the locking tongue 431 toward the second groove side wall 4122. When the locking tongue 431 moves toward the second groove side wall 4122, the button 432 moves in a direction approaching the groove bottom 4123. This guide surface 4321 guides the movement of the locking tongue 431 and can be configured by those skilled in the art according to actual needs.
