Description

Technical Field

[0001] The invention relates to the field of mechanical locking, in particular to a container with a locking device. Background Art

[0002] Existing containers include a container body, a lid mounted on top of the container body, and a locking mechanism for locking the container body and lid. The locking mechanism includes a rotating rod, a locking hook, and a handle, respectively, mounted on each end of the rotating rod. The second side frame of the lid is provided with an opening that mates with the locking hook. Turning the handle drives the rotating rod and the locking hook. When the locking hook engages the opening, the locking mechanism secures the lid to the container body. Currently, during container installation, deformation of the container body after loading can cause the lid to spring up, preventing the locking hook from aligning with the opening, thus preventing the locking mechanism from achieving a secure lock. This requires workers to pull the lid firmly to flatten it and align it with the container body. This process is labor-intensive and inconvenient. Furthermore, due to the high frictional resistance, workers need to exert force to turn the handle, which can easily injure their fingers. Furthermore, the handle may not be able to withstand the force, making it difficult to turn, a time-consuming and labor-intensive process. Summary of the Invention

[0003] In order to overcome the defects in the prior art, an embodiment of the present invention provides a container with a locking device, which is used to solve the problem of labor-intensive and inconvenient operation during the alignment and installation of the cover and the container.

[0004] The present application discloses a container with a locking device, comprising: a container body having a first opening and a first frame provided along an edge of the first opening; a cover body configured to close the first opening, the cover body being provided with a clamping member and a second frame provided along the edge, and the clamping member and the upper surface of the cover body forming a receiving space; a locking device for pressing and locking the cover body to the top of the container body, the locking device comprising: a pressure rod having a clamping portion provided at a lower end thereof, the clamping portion having a second opening adapted to fit the second frame, a support member and an inserting member provided on either side of the second opening, when the pressure rod acts on the second frame through the clamping portion, at least a portion of the inserting member is located within the receiving space of the cover body; a locking assembly rotatably provided on a side wall of the container body, the locking assembly comprising a rotating rod and a locking hook and a handle respectively provided at both ends of the rotating rod; an opening adapted to fit the locking hook is further provided on the second frame, and a force is applied to the pressure rod so that the inserting member abuts against the clamping member, the container is in a locked state, and at least a portion of the locking hook enters the opening.

[0005] Furthermore, a rod-shaped member is provided on the cover body. The rod-shaped member is arranged perpendicular to the second frame, and both ends of the rod-shaped member are fixedly connected to the second frame respectively.

[0006] Furthermore, the clamping member connects the rod-shaped member and the second frame.

[0007] Furthermore, the clamping portion has a first wall, a second wall, and a bottom wall connecting the first wall and the second wall. The first wall, the second wall and the bottom wall together define the second opening of the clamping portion. The length of the first wall is smaller than that of the second wall.

[0008] Furthermore, the second wall is an extension of the pressure rod.

[0009] Furthermore, the insert is provided at one end of the first wall, and the support is provided at one end of the second wall. When the opening of the clamping portion is sleeved on the second frame, the insert is located in the receiving space, and the support is clamped on the lower surface of the first frame of the box.

[0010] Furthermore, a reinforcement body connected to the pressure rod is provided on the outer side of the bottom wall of the clamping portion.

[0011] Furthermore, the first frame is provided with a through hole in the vertical direction, and a fixing piece is provided on the side wall of the box body. The rotating rod passes through the through hole in sequence, and the fixing piece is rotatably arranged on the side wall of the box body, and the lock hook protrudes from the first frame and is located between the box body and the cover body.

[0012] Furthermore, the fixing member is provided with a first mounting hole and a second mounting hole in sequence in the vertical direction.

[0013] Furthermore, the locking device also includes a wrench portion, which includes a rod body and a hollow kit adapted to the handle of the locking portion, and the hollow kit is arranged at an angle to the rod body.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. When the container cover is lifted due to overloading, the operator can press the cover by pulling the pressure rod, so that the operator's action is transferred from the cover to the pressure rod. The pressure rod is easier to apply force than the cover, thus saving manpower and facilitating operation.

[0016] 2. The operator does not need to turn the handle manually, but only needs to turn the rod of the wrench, thereby avoiding the situation where the fingers are crushed due to the excessive concentration of force points during the turning of the handle. The handle that cannot be turned due to poor force can also be turned, which increases the use scenarios of the container.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 9 As shown, the container with a locking device of this embodiment includes:

[0031] The box has a first opening (not shown in the figure), and the edge of the first opening is provided with a first frame 12 ( Figure 9 ), the first frame 12 can be arranged on the periphery of the side wall of the box body so that the first frame 12 protrudes from the plane where the side wall of the box body is located. The first frame 12 can be a rectangular frame. Of course, in other optional embodiments, the shape of the first frame 12 can also be adjusted according to actual needs.

[0032] The lid is configured to seal the first opening. When the lid is placed over the first opening, the lid and the box form a sealed space. A second frame 4 is provided along the upper edge of the lid. The second frame 4 can be located on the upper surface of the lid, protruding from the lid. A rod 5 is also provided on the lid. The rod 5 is perpendicular to the second frame 4, and its ends are fixedly connected to the second frame 4. This reinforces the lid through the rod 5 and the second frame 4, preventing deformation.

[0033] The clamping member 6 connects the rod-shaped member 5 and the second frame 4. The clamping member 6 can be set near the intersection of the rod-shaped member 5 and the second frame 4, so that the clamping member 6 can save the material used for the clamping member 6 while fixing the rod-shaped member 5 and the second frame 4. The clamping member 6 and the upper surface of the cover body form a receiving space.

[0034] The locking device is used to press and lock the cover to the top of the box. The locking device includes:

[0035] The pressure rod 7 has a clamping portion 8 at its lower end. The clamping portion 8 has a second opening 16 adapted to the second frame 4, so that the pressure rod 7 is sleeved on the second frame 4 through the clamping portion 8. Preferably, the pressure rod 7 is a cylindrical rod. Of course, in other optional embodiments, the shape of the pressure rod 7 can be adjusted according to actual needs.

[0036] Specifically, the clamping portion 8 includes a first wall 81, a second wall 82, and a bottom wall 83 connecting the first wall 81 and the second wall 82. Preferably, the length of the first wall 81 is shorter than the length of the second wall 82. The first wall 81, the second wall 82, and the bottom wall 83 collectively define the second opening 16 of the clamping portion 8. In this embodiment, the second wall 82 is an extension of the pressure rod 7 and is integrally formed with the pressure rod 7. Of course, in other embodiments of the present invention, the pressure rod 7 may not be an extension of the pressure rod 7, but may be directly fixedly connected to the bottom wall 83 of the clamping portion 8, which still achieves the same technical effect.

[0037] Preferably, a reinforcement body 13 connected to the pressure rod 7 is further provided on the outer side of the bottom wall 83. The reinforcement body 13 can be solid or hollow. The reinforcement body 13 can reinforce the pressure rod 7, thereby preventing the pressure rod 7 from separating from the clamping portion 8 due to excessive force during use.

[0038] A support member 9 and an insert member 10 are provided on both sides of the second opening 16. Specifically, the support member 9 is provided at one end of the second wall 82, and the insert member 10 is provided at one end of the first wall 81. The insert member 10 can enter the receiving space formed by the clamping member 6 and the upper surface of the cover.

[0039] The insert 10 can be a cylindrical rod extending along the extension direction of the second frame 4. Of course, in other optional embodiments, the insert 10 can also be other structures that can extend into the receiving space. When the pressure rod 7 acts on the second frame 4 through the clamping portion 8, at least a portion of the insert 10 is located within the receiving space of the cover, and the support member 9 is precisely clamped on the lower surface of the first frame 12 of the box body, which can disperse the force applied to the clamping portion 8, thereby preventing excessive pressure at a specific point from causing damage to the box body.

[0040] like Figure 1-3 As shown, the locking assembly is rotatably arranged on the side wall of the box body, and the locking assembly includes a rotating rod 2 and a lock hook 1 and a handle 3 respectively arranged at both ends of the rotating rod 2. The lock hook 1 is arranged at an angle to the rotating rod 2, and the handle 3 can be perpendicular to the rotating rod 2 and fixedly connected.

[0041] Combine Figure 9 As shown, the second frame 4 is also provided with an opening 11 adapted to the lock hook 1, so that the lock hook 1 can be in a locked state after partially entering the opening 11. In detail, the first frame 12 is provided with a through hole 121 in the vertical direction, so that the first frame 12 has a through area in the vertical direction. A fixing member 14 is provided on the side wall of the box body. The fixing member 14 is located below the through hole 121 and is fixedly connected to the side wall of the box body. The rotating rod 2 can pass through the through hole 121 and the fixing member 14 in turn and be rotatably set on the side wall of the box body. After the rotating rod 2 is installed in place, the lock hook 1 protrudes from the first frame 12 and is located between the box body and the cover body.

[0042] More specifically, the fixing member 14 is vertically defined with a first mounting hole 141 and a second mounting hole 142. The rotating rod 2 is rotatably mounted on the fixing member 14 through the first mounting hole 141 and the second mounting hole 142. The diameters of the first mounting hole 141 and the second mounting hole 142 can be the same as or slightly larger than the outer diameter of the rotating rod 2, thereby limiting the position of the rotating rod 2 in the radial direction.

[0043] In this embodiment, during the locking process of the container, a force is applied to the pressure rod 7, so that the insert 10 is held against the clamping member 6, and the support member 9 is clamped on the lower surface of the first frame 12 of the box body. The cover body is driven by the pressure rod 7 to gradually approach the box body until the opening 11 on the second frame 4 corresponds to the locking hook 1, and the handle 3 is rotated so that at least part of the locking hook 1 enters the opening 11, thereby putting the container in a locked state.

[0044] With this structure, when the container is overloaded and the lid is lifted, the operator can shift their force from the lid to the lever by pulling the lever 7 to compress the lid. The lever is more easily able to apply force than the lid, thus saving manpower and facilitating operation. Furthermore, due to the principle of leverage, a smaller force applied to the lever can generate a greater force on the lid, thereby aligning the lid with the container even if the container is deformed after loading, and also saving effort during the alignment process.

[0045] It is worth mentioning that the locking device of the present invention also includes a wrench portion 15, such as Figure 7 and Figure 8 As shown, the wrench portion 15 includes a rod body 151 and a hollow kit 152 adapted to the handle 3 of the locking assembly, that is, the handle 3 can be inserted into the hollow part of the hollow kit 152. The hollow kit 152 is arranged at an angle to the rod body 151. The rod body 151 can be cylindrical to prevent scratching of the hands during use. Of course, the actual shape of the rod body 151 can be adjusted according to actual conditions. One end of the hollow kit 152 is fixedly connected to the rod body 151, and the hollow part of the hollow kit 152 can be slightly larger than the handle 3, so that the hollow kit 152 can be flexibly inserted and removed when it is sleeved on the handle 3.

[0046] In this embodiment, the hollow sleeve 152 is placed on the handle 3, and then the rod body 151 is moved along the rotation direction of the handle 3, so that the rod body 151 rotates axially with the hollow sleeve 152 and the handle 3 located in the hollow sleeve 152, achieving the technical effect of turning the handle 3 by applying a force to the wrench portion 15. Afterwards, the handle 3 drives the rotating rod 2 and the lock hook 1 to rotate, so that the lock hook 1 rotates into the opening 11, achieving the effect of locking the cover body to the container body. During this process, the operator does not need to turn the handle 3 by hand, but only needs to turn the rod body 151, thereby avoiding the situation where the fingers are crushed due to the excessive concentration of force points during the process of turning the handle 3. This allows the handle 3 that cannot be turned due to poor force to be turned to be turned, increasing the use scenarios of the container.

The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
