Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a self-locking container that is easy to open and close. Background Technology

[0002] In logistics services, radiotherapy, and other fields, containers are commonly used to store goods or hazardous materials to facilitate the turnover of goods and shield hazardous materials. To prevent the container from being accidentally opened, multiple mechanical self-locking mechanisms are added between the container body and the top cover, and each mechanical self-locking mechanism is located in a different position to ensure the stability of the top cover when closed.

[0003] However, when the top cover is large, resulting in a large distance between the various mechanical self-locking mechanisms, multiple unlocking personnel are required to switch and maintain the mechanical self-locking mechanisms in different positions to the unlocked state before the top cover can be moved away from the container body or placed on the container body. This requires a large number of unlocking personnel, which is wasteful of manpower and inconvenient to open and close. In addition, during the top cover transfer process, the top cover is also very likely to accidentally injure the unlocking personnel around it, which poses a high safety hazard.

[0004] Finally, when storing toxic or harmful items, it is difficult to unlock all mechanical self-locking mechanisms simultaneously without harming the body, which is not conducive to the quick opening and closing of the top cover. Utility Model Content

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0040] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "two" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0041] This application provides a self-locking container that is easy to open and close, for convenient storage of items. For example... Figure 1 and Figure 7As shown, the self-locking container that is easy to open and close in this application includes an independently set container body 1 and a top cover 2; wherein, the top of the container body 1 is provided with an opening, and the top cover 2 opens or closes the opening of the container body 1 in a lifting manner.

[0042] It should be noted that the container body 1 can be any shape, such as a square or cylindrical structure, and there is no limitation on it; in this embodiment, the container body 1 is preferably a square structure.

[0043] like Figure 1 As shown, the top cover 2 is equipped with multiple mechanical self-locking mechanisms, and the container body 1 is provided with a locked component 11. Each mechanical self-locking mechanism cooperates with the locked component 11 to lock the top cover 2 on the container body 1. Each mechanical self-locking mechanism includes a locking component and a resilient reset component 32. The locking component is installed on the top cover 2 and can switch between a locked position that cooperates with the locked component 11 and an unlocked position that is separated from the locked component 11. The resilient reset component 32 is used to maintain the corresponding locking component in the locked position. In addition, the top cover 2 is also provided with an unlocking component that switches each locking component to the unlocked position, so that each locking component can be unlocked simultaneously through the unlocking component, thereby facilitating the opening and closing of the top cover 2.

[0044] Understandably, the structure of the unlocking component needs to be determined based on the structure of each mechanical self-locking mechanism. For example, if the mechanical self-locking mechanism is a sliding mechanical self-locking mechanism, a corresponding movable unlocking component needs to be used for unlocking; similarly, if the mechanical self-locking mechanism is a rotating mechanical self-locking mechanism, a corresponding rotating unlocking component needs to be used for unlocking.

[0045] Specifically, when the locking element of the mechanical self-locking mechanism is slidably connected to the top cover 2 in the horizontal direction, the mechanical self-locking mechanism is a sliding mechanical self-locking mechanism. At this time, the elastic reset element 32 is a tension spring or a pre-compressed elastic element sleeved on the locking element. The tension spring or pre-compressed elastic element has a reset force that drives the locking element to move to the corresponding locking position, so as to maintain the corresponding locking element in the locking position when there is no external force. When the locking element of the mechanical self-locking mechanism is vertically rotated and installed on the top cover 2, the mechanical self-locking mechanism is a rotating mechanical self-locking mechanism. At this time, the elastic reset element 32 is a torsion spring or a tension spring. The torsion spring or tension spring has a biasing force that drives the locking element to rotate to the corresponding locking position, so as to maintain the corresponding locking element in the locking position when there is no external force.

[0046] It should be noted that the multiple mechanical self-locking mechanisms involved in this application include sliding mechanical self-locking mechanisms and / or rotating mechanical self-locking mechanisms, and are not limited thereto; in this embodiment, the multiple mechanical self-locking mechanisms involved in this application are all sliding mechanical self-locking mechanisms.

[0047] At this time, as Figure 2As shown, the multiple locking components involved in this application include a first locking component 31a and / or a second locking component 31b, and each locking component is located at a different position on the top cover 2 to cooperate in locking the position of the top cover 2 in the closed state.

[0048] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the first locking member 31a includes a slide bar 311, a lock head 312, and a stop head 313; the locked member 11 includes a first locked member 11a, and the first locked member 11a is provided with a lock groove 111 that cooperates with the lock head 312 on the first locking member 31a; the slide bar 311 of the first locking member 31a slides horizontally through the base 21 above the top cover 2, and the lock head 312 and the stop head 313 of the first locking member 31a are respectively connected to the two ends of the corresponding slide bar 311 to prevent the first locking member from being locked. 31a disengages from the corresponding base 21; the elastic reset member 32 on the first locking member 31a is a tension spring disposed between the lock head 312 and the base 21, or the elastic reset member 32 on the first locking member 31a is a pre-compression elastic member disposed between the stop head 313 and the base 21, the pre-compression elastic member is a compression spring or a pre-compression elastic sleeve, wherein the pre-compression elastic sleeve is made of elastic material such as rubber; in this embodiment, the lock head 312 and the stop head 313 of the first locking member 31a are always located outside the corresponding base 21.

[0049] In the free state (i.e., without external force), the elastic reset member 32 drives the lock head 312 of the first locking member 31a into the corresponding lock groove 111 for engagement. At this time, the lock head 312 on the first locking member 31a is in the locked position. When unlocking is required, only an external force needs to be applied to the first locking member 31a to make the lock head 312 on the first locking member 31a move past the corresponding lock groove 111 to reach the unlocked position. At this time, the slide bar 311 of the first locking member 31a is located in the corresponding lock groove 111. In order to smoothly open the top cover 2, as follows... Figure 6 As shown, the first locked member 11a is provided with a first clearance opening 112a that communicates with the lock groove 111; the first clearance opening 112a is located above the corresponding lock groove 111 and communicates with the top of the first locked member 11a to form an opening structure; when the lock head 312 on the first locking member 31a is in the locked position, the lock head 312 on the first locking member 31a cannot cross the lock groove 111 and enter the first clearance opening 112a above, ensuring the stability of the lock; when the lock head 312 on the first locking member 31a is in the unlocked position, the first clearance opening 112a is used to avoid the slide bar 311 on the corresponding first locking member 31a in the vertical direction, so that the slide bar 311 can smoothly enter and exit the corresponding lock groove 111 when the top cover 2 is opened and closed.

[0050] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the second locking member 31b includes a slide bar 311, a lock head 312, and a stop head 313; the locked member 11 includes a second locked member 11b, and the second locked member 11b is provided with a lock groove 111 that cooperates with the lock head 312 on the second locking member 31b; the slide bar 311 of the second locking member 31b slides horizontally through the base 21 above the top cover 2, and the lock head 312 and the stop head 313 of the second locking member 31b are respectively connected to the two ends of the corresponding slide bar 311. The elastic reset member 32 on the second locking member 31b is a pre-compression elastic member disposed between the lock head 312 and the base 21. The pre-compression elastic member is a compression spring or a pre-compression elastic sleeve, wherein the pre-compression elastic sleeve is made of elastic material such as rubber; or, the elastic reset member 32 on the second locking member 31b is a tension spring disposed between the stop head 313 and the base 21; in this embodiment, the lock head 312 and the stop head 313 on the second locking member 31b are always located outside the corresponding base 21.

[0051] In the free state (i.e., without external force), the elastic reset member 32 drives the lock head 312 of the second locking member 31b into the corresponding lock groove 111 for engagement. At this time, the lock head 312 of the second locking member 31b is in the locked position. When unlocking is required, only external force needs to be applied to the second locking member 31b to make the lock head 312 of the second locking member 31b exit the corresponding lock groove 111 and reach the unlocked position. At this time, the second locking member 31b is completely separated from the corresponding lock groove 111, which facilitates the smooth opening and closing of the top cover 2.

[0052] like Figure 2 , Figure 3 , Figures 7 to 10 As shown, the unlocking components involved in the self-locking container include a first unlocking component 4a and / or a second unlocking component 4b; wherein, the first unlocking component 4a is used to unlock the first locking member 31a and maintain the first locking member 31a in the unlocked position; the second unlocking component 4b is used to unlock the second locking member 31b and maintain the second locking member 31b in the unlocked position.

[0053] In this embodiment, as Figure 9As shown, a base plate 5 is detachably and fixedly installed on the top cover 2; the first unlocking assembly 4a includes an unlocking pressure member 41a and a first locking bolt 42a; wherein, the base plate 5 is provided with a first sliding groove 5a parallel to the sliding rod 311 on the first locking member 31a; the bolt shank of the first locking bolt 42a passes through the first sliding groove 5a and is threadedly connected to the unlocking pressure member 41a, and the bolt head of the first locking bolt 42a can cooperate with the unlocking pressure member 41a to clamp the base plate 5, so as to achieve relative fixation between the unlocking pressure member 41a and the base plate 5; when the first locking bolt 42a is loosened, the first locking bolt 42a is released from the top cover 2. The bolt shank of the locking bolt 42a can slide within the first groove 5a, thereby causing the unlocking pressure member 41a to move closer to or further away from the stop head 313 of the first locking member 31a. This pushes the lock head 312 on the first locking member 31a across the corresponding lock groove 111 or avoids the reset first locking member 31a, thus achieving the unlocking and locking of the first locking member 31a. When the first locking member 31a is in the unlocked state, the bolt head of the first locking bolt 42a can cooperate with the unlocking pressure member 41a to clamp the base plate 5, thereby maintaining the unlocked state of the first locking member 31a.

[0054] Of course, in other embodiments, the first unlocking component 4a can also be replaced with, for example... Figure 14 The structure shown is as follows. The first unlocking component 4a includes an unlocking groove 43a for accommodating the stop head 313 on the first locking member 31a, and the unlocking groove 43a is opened on the side of the corresponding base 21 away from the lock head 312; at this time, the shape of the stop head 313 and the unlocking groove 43a can be set according to the actual situation, as long as it is ensured that the stop head 313 of the first locking member 31a can switch between position one aligned with the unlocking groove 43a and position two offset from the unlocking groove 43a at an angle. Thus, when the stop head 313 of the first locking member 31a is aligned with the unlocking groove 43a, the stop head 313 is released, and the stop head 313 will enter the unlocking groove 43a under the action of the elastic reset member 32, thereby placing the lock head 312 of the first locking member 31a in the unlocked position; when the stop head 313 of the first locking member 31a is pulled out of the unlocking groove 43a and rotated so that the stop head 313 and the unlocking groove 43a are set at an off-angle, the stop head 313 will abut against the corresponding base 21 under the action of the elastic reset member 32, thereby placing the lock head 312 of the first locking member 31a in the locked position.

[0055] In this embodiment, as Figure 10As shown, the second unlocking component 4b includes an adapter 41b and a fine-tuning bolt 43b, with one end of the adapter 41b connected to the base plate 5; the fine-tuning bolt 43b is threaded onto the other end of the adapter 41b, and the fine-tuning bolt 43b is aligned with the lock head 312 on the second locking member 31b; thus, by turning the fine-tuning bolt 43b, the lock head 312 on the corresponding second locking member 31b can be pushed out of the lock groove 111 or the reset second locking member 31b can be avoided, thereby realizing the unlocking and locking of the second locking member 31b.

[0056] When the lock head 312 of the second locking member 31b exits the lock groove 111, the bolt rod of the fine-tuning bolt 43b will be located in the lock groove 111; in order to smoothly open the top cover 2, such as Figure 7 As shown, the second locked member 11b is provided with a second clearance opening 112b that communicates with the lock groove 111; the second clearance opening 112b is located above the corresponding lock groove 111 and communicates with the top of the second locked member 11b to form an opening structure; when the lock head 312 of the second locking member 31b is in the locked position, the lock head 312 cannot cross the lock groove 111 and enter the upper second clearance opening 112b, ensuring the stability of the lock; when the lock head 312 of the second locking member 31b is in the unlocked position, the second clearance opening 112 is used to avoid the bolt rod of the fine adjustment bolt 43b in the vertical direction, so that the bolt rod of the fine adjustment bolt 43b can smoothly enter and exit the lock groove 111 when the top cover 2 is opened and closed.

[0057] In a further embodiment, such as Figure 10 As shown, the adapter 41b is mounted on the substrate 5 by the second locking bolt 42b. The adapter 41b has a through hole, and the bolt shank of the second locking bolt 42b passes through the through hole of the adapter 41b and is threaded to the substrate 5. Thus, when the substrate 5 and the second unlocking component 4b thereon are idle, the second locking bolt 42b can be loosened, and the adapter 41b can be rotated upward to the idle position (i.e., rotated to a position where the lowest point of the adapter 41b is not lower than the lowest point of the substrate 5) and then locked. At this time, when the substrate 5 is stored, the second unlocking component 42 is less likely to be damaged.

[0058] In a further embodiment, such as Figure 11 As shown, the through hole on the adapter 41b extends toward the fine-tuning bolt 43b to form a second groove 411b; the bolt shank of the second locking bolt 42b can slide within the second groove 411b; thus, the distance between the fine-tuning bolt 43b and the base plate 5 can be adjusted as needed, thereby satisfying the unlocking of the second locking member 31b at different height positions.

[0059] In another embodiment, such as Figure 12As shown, the second unlocking component 4b includes an unlocking puller 44b and a mounting bolt 45b; wherein, the base plate 5 is provided with a horizontal groove 5b parallel to the slide bar 311 on the second locking member 31b; the bolt shank of the mounting bolt 45b passes through the horizontal groove 5b and is threadedly connected to the unlocking puller 44b, and the bolt head of the mounting bolt 45b can cooperate with the unlocking puller 44b to clamp the base plate 5; when the mounting bolt 45b is loosened, the bolt shank of the mounting bolt 45b can slide in the horizontal groove 5b, so as to drive the unlocking puller 44b to approach or move away from the stop head 313 of the second locking member 31b, so as to pull the lock head 312 on the second locking member 31b out of the corresponding lock groove 111 or to avoid the reset second locking member 31b.

[0060] Of course, in other embodiments, the structure of the second unlocking component 4b is as follows: Figure 13 As shown, it includes an unlocking block 46b formed on the base 21 of the second locking member 3b, and the unlocking block 46b is located on the side of the base 21 away from the lock head 312; thus, the stop head 313 of the second locking member 31b can switch between a locked position in contact with the base 21 and an unlocked position in contact with the unlocking block 46b.

[0061] To ensure the stability of the stop head 313 on the second locking member 31b at the unlocked position, there are two unlocking blocks 46b, and the two unlocking blocks 46b are symmetrically arranged about the slide bar 311 of the second locking member 31b. At the same time, the two unlocking blocks 46b cooperate to form a locking groove for accommodating the corresponding stop head 313. Thus, when the stop head 313 of the second locking member 31b rotates to the position aligned with the locking groove, it will enter the locking groove from the left and right sides of the elastic reset member 32 and contact the corresponding base 21. When the stop head 313 of the second locking member 31b is pulled out of the locking groove and rotated to a position at an angle opposite to the locking groove and released, the stop head 313 will abut against the two unlocking blocks 46b under the action of the elastic reset member 32, completing the unlocking operation.

[0062] like Figure 7 As shown, a support assembly is provided above the top cover 2, and the base plate 5 is detachably mounted on the support assembly.

[0063] To ensure the stability of the substrate 5, there are two support components, which are spaced apart.

[0064] It should be noted that the detachable installation methods of the substrate 5 and the support assembly include, but are not limited to, the following two:

[0065] Method 1: The base plate 5 is detachably mounted on the support assembly by bolts.

[0066] Method 2: The substrate 5 is detachably mounted on the support assembly via a clamping mechanism. Specifically, such as... Figure 11As shown, the support assembly includes a support block 22 formed above the top cover 2 and a connecting plate 23 bolted to the support block 22; wherein, the connecting plate 23 is suspended on one side facing the center of the top cover 2 or on the side away from the center of the top cover 2 to form a suspended part; the clamping mechanism includes a clamping block 7 and a clamping bolt; a first through hole is provided on the suspended part of the connecting plate 23, and a second through hole aligned with the first through hole is provided on the substrate 5; the bolt shank of the clamping bolt passes through the second through hole of the substrate 5 and the first through hole of the connecting plate 23 in sequence and is bolted to the clamping block 7 below the suspended part, and the bolt head of the clamping bolt can cooperate with the clamping block 7 to clamp the suspended part of the substrate 5 and the connecting plate 23, thereby realizing the relative fixation of the substrate 5 and the connecting plate 23.

[0067] like Figure 11 As shown, the top cover 2 is provided with a lifting ring 6 to facilitate the lifting of the top cover 2 by a lifting device, and to complete the opening and closing of the top cover 2; in this embodiment, the lifting ring 6 is set on the top of the clamping bolt or the top of the base plate 5 to achieve relative fixation between the lifting ring 6 and the top cover 2.

[0068] In a preferred embodiment, such as Figure 3 As shown, the container body 1 is equipped with a shelf 8 for placing items.

[0069] When the self-locking container is used to store radioactive sources such as target segments, the materials of both the container body 1 and the top cover 2 include radiation protection materials to provide radiation shielding and thus prevent the radiation emitted by the radioactive source from damaging the human body.

[0070] It should be noted that radiation protection materials include, but are not limited to, lead or radiation-proof glass; in this embodiment, lead is preferred as the radiation protection material.

[0071] Since lead is a high-density, toxic heavy metal, to reduce the weight of the container body 1, the container body 1 preferably adopts a double-layer structure. Specifically, the container body 1 includes an inner lead layer and an outer radiation-protective activation layer. The material of the radiation-protective activation layer includes, but is not limited to, low-activation steel (such as 101 stainless steel), high-density polyethylene, or boron-containing polyethylene composite materials. In this embodiment, the radiation-protective activation layer is 101 stainless steel.

[0072] Of course, such as Figure 3 As shown, the top cover 2 includes an embedded part and a closed part located above the embedded part; wherein, the embedded part fits with the opening of the container body 1, and the embedded part is composed of radiation protection materials such as lead; the closed part is placed on the top of the container body 1, and the closed part is composed of low-activation steel such as 101 stainless steel; such a design can not only reduce the weight of the top cover 2, but also avoid lead damage to the human body, thus balancing weight and safety.

[0073] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
