Description

Technical Field

[0001] The present invention relates to the field of containers, in particular to a container. Background Art

[0002] Existing storage containers, especially those requiring sealing for goods, are generally equipped with lids. After loading the goods into the container, the lid is closed to create a relatively complete and enclosed storage environment. This prevents the goods from being affected by moisture, deterioration, or contamination during transportation. Furthermore, to increase the stability of the container and lid and prevent the lid from separating from the container due to bumps during transportation, connecting structures between the lid and the container are added, such as locks, hinges, and elastic hooks. However, these connecting members are generally installed on the container and lid separately via rivets or screws, which achieve the connection or locking of the container and lid. However, these fasteners require numerous components, are complex to install, and have high installation requirements, making them unsuitable for mass production. Furthermore, once the container is locked, it is easy to accidentally touch the connecting structure, causing the lid to separate from the container. Summary of the Invention

[0003] The object of the present invention is to provide a container, the locking device of which has fewer installation parts and simpler procedures, is convenient for mass production, and can prevent the box body and the box cover from being separated due to accidental touch.

[0004] To solve the above technical problems, an embodiment of the present invention provides a container, comprising:

[0005] Box;

[0006] a box cover, the box cover being used to open or close the box body; and

[0007] A locking device, comprising: a locking member, a reset member, and a control; the locking member is hingedly connected to one of the box body or the box cover, and the control is movably connected to the locking member; one end of the reset member abuts against the locking member, and the other end of the reset member abuts against the control; the control includes a lock tongue, and the reset member provides a resisting force to the lock tongue;

[0008] The locking member is used to drive the reset member and the control to flip around the hinge between the locking member and one of the box body or the box cover; wherein, when the locking member drives the control to flip to a preset position, the locking tongue can be operably locked to the other of the box body or the box cover through the thrust of the reset member.

[0009] Compared to the prior art, the container locking device of the present invention is mounted on the container. A locking member is hingedly connected to one of the container body or lid via a hinge axis. The hinge axis drives the locking member to rotate, while the two ends of the return member respectively abut against the control and the locking member. When the locking member rotates about the hinge axis, the control also rotates with the locking member. When the control is rotated to the other container body or lid and locked, the container is locked. When the container body and lid need to be separated, the control must first be moved away from the locked position of the other container body or lid, and then the locking member must be rotated about the hinge axis to separate the container body and lid. Otherwise, only moving the control away from the locked position of the other container body or lid will not separate the container body and lid. This prevents the container body and lid from being separated by accidentally touching the control or hitting the control due to collision. Containers equipped with this locking device are therefore safer to use and prevent the lid and container from being separated and unlocked due to accidental touching. In addition, the container locking device of the embodiment of the present invention has fewer components, a simple structure, and is easy to install, which is conducive to mass production. It can also avoid accidental contact that causes the box body and the box cover to separate.

[0058] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0059] An embodiment of the present invention provides a container 10, which includes: a box body 100, a box lid 200 and a locking device 300. The box lid 200 is used to open or close the box body 100. The locking device 300 includes: a locking member, a reset member and a control. The locking member is hingedly connected to the box body 100, and the control is movably connected to the locking member. One end of the reset member abuts against the locking member, and the other end of the reset member abuts against the control. The control includes a lock tongue, and the reset member provides a thrust to the lock tongue. The locking member is used to drive the reset member and the control to flip around the hinge between the locking member and the box body 100. When the locking member drives the control to flip to a preset position, the lock tongue can be operably locked to the box lid 200 through the thrust of the reset member.

[0060] The locking device 300 of the container 10 in the embodiment of the present invention is installed on the container 10, and the locking member is hingedly connected to one of the box body 100 or the box cover 200 through a hinge shaft, so that the hinge shaft drives the locking member to rotate, and the two ends of the reset member are respectively against the control and the locking member. When the locking member rotates around the hinge shaft, the control also rotates with the rotation of the locking member. When the control rotates to the other one of the box body 100 or the box cover 200 and locks it, the container 10 is locked. When the box body 100 and the box cover 200 need to be separated, the control must first be moved away from the other locked position in the box body 100 or the box cover 200, and then the locking member must be rotated around the hinge axis to separate the box body 100 and the box cover 200. Otherwise, simply moving the control away from the other locked position in the box body 100 or the box cover 200 will not separate the box body 100 and the box cover 200, thereby preventing the box body 100 and the box cover 200 from being separated by accidental touch or collision. The locking device 300 of the container 10 of the embodiment of the present invention has fewer components, a simple structure, and is easy to install, which is conducive to mass production. In addition, it can prevent the box body 100 and the box cover 200 from being separated by accidental touch.

[0061] It should be understood that although the embodiment of the present invention shows that the lock member is hingedly connected to the box body 100, and the lock member is used to drive the reset member and the control to flip around the hinge of the lock member and the box body 100, when the lock member drives the control to flip to the preset position, the lock tongue can be operably locked to the box cover 200 through the resistance force of the reset member, but in other embodiments, the lock member can also be hingedly connected to the box cover 200, and the lock member is used to drive the reset member and the control to flip around the hinge of the lock member and the box cover 200, when the lock member drives the control to flip to the preset position, the lock tongue can be operably locked to the box cover 100 through the resistance force of the reset member. This embodiment does not depart from the scope of the present invention, and those skilled in the art can make arrangements according to actual needs.

[0062] The scope of the present invention is described in detail below with two examples.

[0063] Example 1

[0064] like Figure 1 As shown, the container 10 includes: a box body 100, a box cover 200 and a locking device 300. The box cover 200 is used to open or close the box body 100. Figure 2As shown, the locking device 300 includes: a locking member 31, a reset member 32 and a control 33. The locking member 31 is hingedly connected to the box body 100, and the control 33 is movably connected to the locking member 31. One end of the reset member 32 abuts against the locking member 31, and the other end of the reset member 32 abuts against the control 33. The control 33 includes a lock tongue 331, and the reset member 32 provides a thrust to the lock tongue 331. The locking member 31 is used to drive the reset member 32 and the control 33 to flip around the hinge between the locking member 31 and the box body 100. Figure 3 As shown, when the locking member 31 drives the control 33 to flip to the preset position, the locking tongue 331 can be operatively locked to the box cover 200 by the pushing force of the reset member 32 .

[0065] Specifically, combined Figure 6 A partial enlarged view of B in the middle Figure 7 As shown, the locking member 31 includes a lock body 311 and a hinge axis 312 disposed at the end of the lock body 311. A lock tongue 331 faces the hinge axis 312. A protruding stopper 21 is provided on the box lid 200. The lock body 311 is provided with a through-hole 3111. When the locking member 31 is flipped to a predetermined position, the stopper 21 and the lock tongue 331 operably cooperate to lock through the through-hole 3111. Technicians can adjust the configuration based on actual needs. It should be understood that in embodiments where the locking member 31 is hingedly connected to the box lid 200, the stopper 21 is provided on the box body 100.

[0066] Preferably, when the locking member 31 is flipped to the preset position, Figure 3 When the locking member 31 is in the middle position, the stopper 21 passes through the through-opening 3111, and the locking tongue 331 is operatively locked with the stopper 21. Those skilled in the art can adjust the configuration according to actual needs. It should be understood that it does not depart from the scope of the present invention to configure the locking tongue 331 to pass through the through-opening 3111 and operatively lock with the stopper 21 when the locking member 31 is flipped to the preset position.

[0067] Further, if Figure 3 As shown, the lock member 31 is hingedly connected to the box body 100, the stopper 21 is arranged on the top of the box cover 200, the lock body 311 has a first mounting surface 3112, and a second mounting surface 3113 arranged opposite to the first mounting surface 3112, and the lock tongue 331 is located on the side where the second mounting surface 3113 is located. Figure 2As shown, a portion of the second mounting surface 3113 bends and extends toward the side of the first mounting surface 3112 to form a receiving portion 3114. When the locking member 31 is flipped to the preset position, the receiving portion 3114 abuts against the top of the box lid 200. By arranging the receiving portion 3114 to abut against the top of the box lid 200, when the locking device 300 locks the container 10, the box body 100 and the box lid 200 are tightly fitted together. It should be understood that in the embodiment where the locking member 31 is hingedly connected to the box lid 200, the stop portion 21 is provided on the box body 100. When the locking member 31 is flipped to the preset position, the receiving portion 3114 abuts against the box body 100.

[0068] In such Figure 1 In the embodiment, the side where the locking device is installed is the locking side, and the stopper 21 is as shown in FIG. Figure 3 The plate extends toward the locking side, and the end of the plate toward the locking side is bent upward to form a hook. The locking tongue can abut against the hook to form a locking mechanism that locks the cover. It is understood that in other embodiments, the cover can be recessed to form a stop, allowing the locking tongue to extend into the recess and abut against the sidewall of the recess to form a lock. Alternatively, the locking tongue can be a locking hook, with the stop 21 being a hole, and the locking hook hooking into the hole to form a locking mechanism that locks the cover.

[0069] In addition, if Figure 3 As shown, the control 33 also includes a button 332 fixedly connected to the lock tongue 331, and the button 332 is hingedly connected to the lock member 31, and the other end of the reset member 32 is against the button 332. The reset member 32 provides a resisting force to the button 332, so that the button 332 can be operably rotated around the hinge with the lock member 31 and drive the lock tongue 331 to move toward the side where the through-opening 3111 is located. When it is necessary to lock the container 10, the hinge shaft 312 drives the lock member 31 to rotate, and the two ends of the reset member 32 are respectively against the button 332 and the lock member 31. When the lock member 31 rotates around the hinge shaft 312, the button 332 and the lock tongue 331 also rotate with the rotation of the lock member 31. When the lock tongue 331 rotates until the stop portion 21 on the box cover 200 is locked, the container 10 is locked. The operation of opening the container 10 is opposite to the above steps. The process of opening the container 10 can be referred to. Figure 4 and Figure 5 Those skilled in the art can make settings according to actual needs.

[0070] Preferably, if Figure 3As shown, the button 332 has a protruding connecting shaft 3321, which is hingedly connected to the locking member 31. The reset member 32 includes a torsion spring portion 321 that is sleeved on the connecting shaft 3321, and a first connecting portion 322 and a second connecting portion 323 that extend from both ends of the torsion spring portion 321. The first connecting portion 322 abuts against the button 332, and the second connecting portion 323 abuts against the locking member 31. Those skilled in the art can configure the reset member 32 according to actual needs. In addition to the above structure, the reset member 32 may also have other elastic structures, such as a spring.

[0071] Furthermore, when the locking member 31 is flipped to a preset position, the first connecting portion 322 pushes the locking tongue 331 to rotate until it contacts the stopper 21. Those skilled in the art can make the configuration according to actual needs.

[0072] Example 2

[0073] like Figure 8 As shown, the container 10 includes: a box body 100, a box cover 200 and a locking device 300. The box cover 200 is used to open or close the box body 100. Figure 9 As shown, the locking device 300 includes: a locking member 41, a reset member 42 and a control 43. The locking member 41 is hingedly connected to the box body 100, and the control 43 is movably connected to the locking member 41. One end of the reset member 42 abuts against the locking member 41, and the other end of the reset member 42 abuts against the control 43. The control 43 includes a lock tongue 431, and the reset member 42 provides a thrust to the lock tongue 431. The locking member 41 is used to drive the reset member 42 and the control 43 to flip around the hinge between the locking member 41 and the box body 100. Figure 10 As shown, when the locking member 41 drives the control 43 to flip to the preset position, the locking tongue 431 can be operatively locked to the box cover 200 by the pushing force of the reset member 42 .

[0074] Specifically, if Figure 10As shown, the lock tongue 431 is movably arranged on the lock member 41, and the other end of the reset member 42 is against the lock tongue 431, and has a pushing force to push the lock tongue 431 toward one end away from the reset member 42. The control 43 also includes a button 432 movably connected to the lock member 41, and the button 432 is also against the lock tongue 431 and is movably arranged. When the reset member 42 pushes the lock tongue 431 to move, the lock tongue 431 pushes the button 432 to move in a direction perpendicular to the movement of the lock tongue 431. When locking the container 10, the lock member 41 is rotated, and the lock member 41 drives the reset member 42 and the control 43 to flip around the hinge of the lock member 41 and the box body 100. When the lock member 41 drives the control 43 to flip to a preset position, the lock tongue 431 can be operatively locked to the box lid 200 by the push force of the reset member 42. In the absence of external force, the reset member 42 is in a relaxed state, and the reset member 42 can keep the lock tongue 431 locked to the box lid 200 in the absence of external force. When the box lid 200 needs to be opened, the button 432 is pressed by hand, and the button 432 pushes the lock tongue 431 away from the box lid 200, and then compresses the reset member 42. Then, the lock member 41 needs to be flipped along the hinge with the box body 100, so that the lock member 41 is separated from the box lid 200. It should be understood that in the above embodiment, the locking member 41 is hingedly connected to the box body 100 , and those skilled in the art may also hingely connect the locking member 41 to the box cover 200 according to actual needs.

[0075] Preferably, if Figure 9 As shown, the locking member 41 is provided with a mounting groove 412, which has a pair of first groove side walls 4121 that are relatively spaced apart, a second groove side wall 4122 that is connected to the pair of first groove side walls 4121, and a groove bottom 4123 that connects the pair of first groove side walls 4121 and the second groove side walls 4122. The second groove side wall 4122 is located on the side of the mounting groove 412 that is away from the hinged connection between the locking member 41 and the box body 100, and the pair of first groove side walls 4121 and the second groove side walls 4122 surround the groove bottom 4123. The locking tongue 431 is slidably connected to the pair of first groove side walls 4121, and one end of the reset member 42 abuts against the second groove side wall 4122, and the other end of the reset member 42 abuts against one end of the locking tongue 431 that faces the second groove side wall 4122. Figure 10 As shown, the button 432 is slidably connected to the pair of second slot side walls 4122, and the button 432 has a guide surface 4321 facing the second slot side walls 4122 and abutting against the lock tongue 431. When the lock tongue 431 moves relative to the second slot side walls 4122, the button 432 moves toward the direction close to the slot bottom 4123. The guide surface 4321 provides guidance for the movement of the lock tongue 431, and those skilled in the art can configure it according to actual needs.

[0076] Furthermore, the embodiment of Example 2 may also be provided with a receiving portion as in Example 1. When the locking member 41 is flipped to a preset position, the receiving portion abuts against the top of the box lid 200. By providing a receiving portion abutting against the top of the box lid 200, when the locking device 300 locks the container 10, the box body 100 and the box lid 200 fit tightly together. It should be understood that in embodiments where the locking member 41 is hingedly connected to the box lid 200, when the locking member 41 is flipped to a preset position, the receiving portion abuts against the box lid 200.

[0077] Further, if Figure 9 As shown, the lock tongue 431 includes a lock tongue body 4311 and a connecting shaft 4312 protruding from the side of the lock tongue body 4311. The reset member 42 abuts against the lock tongue body 4311. The lock tongue body 4311 is used to lock the box cover 200 under the thrust of the reset member 42. The first slot sidewall 4121 has a first elongated slot 4124 for inserting the connecting shaft 4312. The first elongated slot 4124 extends in the same direction as the movement of the lock tongue 431. The guide surface 4321 has a gradually decreasing slope facing away from the slot bottom 4123 and between the second slot sidewall 4122. The guide surface 4321 abuts against the side of the connecting shaft 4312 facing away from the lock tongue body 4311 and the reset member 42. The first elongated slot 4124 cooperates with the connecting shaft 4312 so that the lock tongue 431 can only move along the direction of the first elongated slot 4124. It is understandable that in other embodiments, the lock tongue body 4311 may have an inclined guide surface, and the button 432 may have a flat surface that abuts against the inclined guide surface. For example, when the button 432 is pressed to move horizontally, the lock tongue may move vertically, that is, the movement direction of the button is perpendicular to the movement direction of the lock tongue. Figure 10 and Figure 11 , Figure 10 FIG2 shows a cross-sectional structural diagram of the locking device 300 when the box body 100 and the box cover 200 are locked. Figure 11 The schematic diagram of the structure of the cross-section of the locking device 300 when the button 432 is pressed is shown. Figure 12 and Figure 13 As shown, when the button 432 is pressed, that is, the button 432 is pressed close to the lock member 41, the lock tongue 431 will move along the guide surface 4321, and the reset member 42 will be compressed, so the lock tongue 431 is separated from the box cover 200, and then the lock member 41 is bent so that the lock member 41 rotates around the hinge axis, so that the box body 100 and the box cover 200 can be separated. The process of locking the box body 100 and the box cover 200 is the opposite of the above process. It should be understood that the above embodiment is that the lock member 41 is hingedly connected to the box body 100. Those skilled in the art can also hingely connect the lock member 41 to the box cover 200 according to actual needs. At this time, the lock tongue body 4311 can be used to lock the box body 100 under the thrust of the reset member 42. The reset member can be as shown Figure 9The spring structure in the embodiment may also be a spring sheet or an elastic block in other embodiments.

[0078] Preferably, combined Figure 9 and Figure 11 As shown, the button 432 comprises a first panel 4322, a pair of connecting ears 4323 disposed oppositely on either side of the first panel 4322, and an insert plate 4324 disposed between the pair of connecting ears 4323 and connected to the first panel 4322. The pair of connecting ears 4323 are respectively slidably connected to the pair of first slot sidewalls 4121. The insert plate 4324 is operably inserted into the mounting slot 412 and faces the second slot sidewall 4122. The guide surface 4321 is located on the side of the first panel 4322 facing the slot bottom 4123, and the lock tongue body 4311 is located between the slot bottom 4123 and the first panel 4322. The reset member 42 is operable to push the lock tongue body 4311 toward the side away from the insert plate 4324 and partially expose it outside the first panel 4322. Those skilled in the art can modify the configuration according to actual needs.

[0079] In addition, if Figure 9 As shown, the locking member 41 is provided with a through hole 413, and the through hole 413 is located on the side of the groove bottom 4123 away from the second groove side wall 4122. Figure 10 As shown, when the lock tongue body 4311 is pushed by the reset member 42 and partially exposed to the outside of the first panel 4322, it is opposite to the through opening 413. This arrangement is more reasonable, and those skilled in the art can make arrangements according to actual needs.

[0080] Further, if Figure 10 As shown, the box cover 200 is provided with a stopper 21, and the locking member 41 is hingedly connected to the box body 100. When the locking member 41 is flipped to a preset position, the reset member 42 pushes the locking tongue 431 toward the top of the box cover 200, and the locking tongue 431 can be operatively abutted against the stopper 21. It should be understood that in the above embodiment, the locking member 41 is hingedly connected to the box body 100. Those skilled in the art can also hinge the locking member 41 to the box cover 200 according to actual needs, so that the stopper 21 is located on the box body 100.

[0081] In such Figure 8 In the embodiment, the side where the locking device is installed is the locking side, and the stopper 21 is as shown in FIG. Figure 11 The plate extends toward the locking side, and the end of the plate toward the locking side is bent upward to form a hook. The locking tongue can abut against the hook to form a locking mechanism that locks the cover. It is understood that in other embodiments, the cover can be recessed to form a stop, allowing the locking tongue to extend into the recess and abut against the sidewall of the recess to form a lock. Alternatively, the locking tongue can be a locking hook, with the stop 21 being a hole, and the locking hook hooking into the hole to form a locking mechanism that locks the cover.

[0082] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0083] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be construed as limited to the specific embodiments disclosed in the specification and claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
