Description

Technical Field

[0001] This utility model belongs to the field of storage container technology, specifically relating to a top cover and toolbox. Background Technology

[0002] A toolbox is a container used to store tools and various household items. Tools are usually placed inside, and the toolbox is then locked with a buckle, allowing people to safely move and store tools.

[0003] Toolboxes generally consist of a box body and a lid that closes the box body. The lid, which closes onto the box body, is usually secured by a locking mechanism. Currently, common locking mechanisms include push-button locks and snap-on locks.

[0004] However, current push-button locks rely on spring structures, making them prone to damage, jamming, or failure. They also have numerous parts, requiring multiple independent components to work together, resulting in high overall costs. Hook-and-loop locks similarly have a large number of parts, leading to high overall costs. Furthermore, each component in a hook-and-loop lock requires manual assembly, as does the spring in a push-button lock. This not only results in low efficiency but also presents challenges in aligning multiple components. Therefore, current lock structures mounted on the cabinet are complex, leading to cumbersome assembly and low production efficiency. Moreover, these lock structures are exposed on the outside of the cabinet, making them susceptible to snagging on external items and causing damage, resulting in a poor user experience. Utility Model Content

[0005] To address the shortcomings of existing technologies, a top cover and toolbox are provided to solve the problems of low assembly efficiency and poor user experience in toolbox locking structures.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a top cover, adapted to the opening of a box, the top cover comprising:

[0007] Cover;

[0008] A cover plate is disposed on the cover body, and a receiving cavity is formed between the cover plate and the cover body. A first slot communicating with the outside is provided on the receiving cavity.

[0009] A locking member is slidably disposed in the receiving cavity. The locking member has a snap-fit ​​portion that can pass through the first slot. The locking member is used to linearly reciprocate along a first direction to drive the snap-fit ​​portion to lock with the housing at the end of its stroke.

[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0011] A cover plate is set on the top cover of the box to form a receiving cavity. The locking component is located in the receiving cavity. Compared with the exposed part on the outside of the box, the overall structure is not easy to be scratched and damaged. Moreover, the overall structure is simple, with fewer parts and less space occupied, and the assembly efficiency is high. The locking structure can be realized by the two parts of the cover and the locking component. The snap-fit ​​part on the locking component cooperates with the snap-fit ​​groove on the box to achieve snap-fit ​​fixation. The locking component slides in the receiving cavity and locks and unlocks by pushing and pulling. The operation is simple. Moreover, the locking structure is located on the cover, and unlocking and locking can be completed while holding the cover, which can be operated quickly with one hand.

[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0013] In one embodiment, the accommodating cavity has a second slot communicating with the outside, and the locking member is provided with a push button that is accommodated in the second slot. The push button is used to drive the locking member to reciprocate along a first direction.

[0014] By opening a second slot, a push button is provided on the locking component and protrudes from the second slot. When controlling the reciprocating movement of the locking component along the first direction, it can be achieved by pushing the push button, which is convenient and quick.

[0015] In one embodiment, the inner diameter of the receiving cavity in a first direction is greater than the length of the locking member in that direction, and the receiving cavity is used to limit the reciprocating range of the locking member in the first direction.

[0016] The inner diameter of the accommodating cavity is set to be greater than the length of the locking member. The locking member can reciprocate in the accommodating cavity along the first direction. The accommodating cavity serves to limit the reciprocating movement of the locking member to the limit position. When the locking member moves to the end of its stroke, it can match and lock with the slot.

[0017] In one embodiment, a limiting groove and a limiting rib are provided on the inner sidewall of the accommodating cavity along a first direction, and the other is provided on the locking member, with the limiting rib slidingly matched in the limiting groove.

[0018] By setting matching limiting grooves and limiting ribs between the locking member and the receiving cavity, the reciprocating movement of the locking member is restricted by the limiting grooves. The limiting grooves are arranged along the first direction, so that the locking member can ensure the accuracy of movement when it is subjected to force.

[0019] In one embodiment, it further includes a first limiting mechanism and two second limiting mechanisms, the two second limiting mechanisms being spaced apart at both ends of the first limiting mechanism along a first direction;

[0020] One of the first limiting mechanism or the second limiting mechanism is disposed on the locking member;

[0021] When the first limiting mechanism and the second limiting mechanisms at both ends are in contact and cooperate with each other, they are used to limit the locking member at the end of the stroke and the beginning of the stroke, respectively.

[0022] By utilizing the first and second limiting mechanisms that cooperate with each other, it is possible to ensure that the locking member and the housing are in a locked or unlocked state. The two second limiting mechanisms are located at both ends of the first limiting mechanism, which ensures that the locking member is restricted in the locked state and will not easily disengage from the locked state. At the same time, it also ensures that the locking member is restricted in the unlocked state and will not easily disengage from the locked state. This ensures the stability of the locking member at both ends of its stroke, so that the locking member can be stably maintained in the locked and unlocked states.

[0023] In one embodiment, the first limiting mechanism and the second limiting mechanism are magnetic suction components that attract each other, and the effective magnetic force distance between two adjacent magnetic suction components is less than the actual distance between them.

[0024] In one embodiment, the first limiting mechanism is one of a matching stop groove or a stop block, and the second limiting mechanism is the other of the two. A deformation strip is provided on the cover plate along the first direction, and one of the first limiting mechanism or the second limiting mechanism is disposed on the deformation strip of the cover plate.

[0025] In one embodiment, the cover is provided with a handle, which forms a gripping part on the cover by protruding outward and / or concave in a preset deformation direction.

[0026] In one embodiment, the edge of the gripping part of the handle is provided with at least one anti-slip rib.

[0027] On the other hand, this utility model also discloses a toolbox, which includes:

[0028] The aforementioned top cover;

[0029] The housing has a slot that matches the snap-fit ​​part.

[0030] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0031] 1. The cover plate and locking component work together with the cover body to form a locking structure, which reduces the previous cumbersome assembly method and complex locking structure, thus reducing production costs;

[0032] 2. The locking components are located within the accommodating cavity and are not exposed, making the entire top cover clean and tidy, reducing mold investment and lowering production costs;

[0033] 3. The locking mechanism is located on the top cover, making operation more convenient and quick, and enabling one-handed operation.

[0034] 4. Through the cooperation of three limiting mechanisms, the second limiting mechanism at both ends cooperates with the first limiting mechanism at both ends of the stroke. This can limit the locking part when it is at the beginning and end of the reciprocating motion, thus preventing the locking part from being locked or disengaged at both ends and avoiding the locking state from easily disengaging during the use of the cover.

[0035] 5. The handle is integrated into the lid, which further improves assembly efficiency and makes the whole structure have a higher load-bearing capacity and greater strength. Attached Figure Description

[0051] Example 1

[0052] like Figure 1-7 As shown, the present invention provides a top cover that is adapted to the opening of a box. The top cover includes: a cover body 1, a cover plate 2, and a locking member 5.

[0053] The cover 1 is used to fit and close to the opening of the box. The cover plate 2 is disposed on the cover 1. The cover plate 2 can be disposed on the top or bottom of the cover 1. The position of the cover plate 2 on the cover 1 is sufficient to allow the locking member 5 to extend out of the edge of the cover 1. Preferably, the cover plate 2 is disposed on one side edge of the cover 1. The cover plate 2 and the cover 1 can be fixed by welding. The cover plate 2 and the cover 1 form a receiving cavity. Specifically, the edge of the cover plate 2 forms a protruding end edge. After the cover plate 2 is fixed on the cover 1, a receiving cavity with a certain receiving space is formed between the cover plate 2 and the cover 1. The thickness of the receiving cavity matches the locking member 5. The receiving cavity has a first slot 3 that communicates with the outside. The position of the first slot 3 is specifically located on the side wall of the receiving cavity. Preferably, the locking member 5 is slidably disposed in the receiving cavity near the edge of the cover 1. The locking member 5 is a sheet-shaped locking member 5 that matches the receiving cavity. The locking member 5 has a snap-fit ​​portion 6 that can pass through the first slot 3. Specifically, the snap-fit ​​portion 6 is integrally formed with the locking member 5. The width of the snap-fit ​​portion 6 is ensured to be able to pass through the first slot 3, that is, the width of the first slot 3 is greater than the width of the snap-fit ​​portion 6. The locking member 5 is used to linearly reciprocate along the first direction to drive the snap-fit ​​portion 6 to lock with the box at the end of the stroke. When the snap-fit ​​portion 6 is at the beginning of the stroke, it is in a separated state from the box. That is, during the movement of the locking member 5 in the first direction, when it is at the beginning, the snap-fit ​​portion 6 is in a separated state from the box, and when it is at the end, the snap-fit ​​portion 6 is in a locked state with the box.

[0054] like Figure 7 As shown, the travel end and the travel beginning are the two extreme positions of the locking member 5 during the reciprocating movement in the first direction. When the locking member 5 moves to the travel end in the first direction and can no longer move, this is the position where the locking part 6 can lock with the external slot. When the locking member 5 moves in the opposite direction to the travel beginning in the first direction and can no longer move, this is the position where the locking part 6 can separate from the external slot.

[0055] Specifically, the opening of the housing is provided with a slot that engages with the locking part 6 on the locking member 5. When the locking part 6 moves to the end of its travel, it contacts the slot to form a lock. When the locking part 6 moves back, it separates from the slot to complete the unlocking.

[0056] The first direction is a linear reciprocating movement direction perpendicular to the surface of the cover 1, which ensures that the snap-fit ​​part 6 can extend through the first slot 3 and engage or disengage with the external slot, thereby fixing the cover and the box with the slot. That is, the locking member 5 reciprocates in the flat accommodating cavity formed by the cover plate 2 and the cover 1, driving the snap-fit ​​part 6 to reciprocate, realizing engagement and disengagement with the slot. Moreover, the flattened design of the accommodating cavity saves a lot of space.

[0057] In one embodiment, the first direction is the longitudinal horizontal direction, that is, along the direction perpendicular to the horizontal length of the top cover. The slot is set outside the first slot 3. When moving back and forth along the first direction, the locking part 6 in the locking member 5 extends out of the first slot 3 and matches and locks with the slot in the outer box. The locking part 6 retracts into the first slot 3 and separates from the slot. This back and forth movement realizes the switching between the locking and separating states.

[0058] In another embodiment, the first direction is a horizontal direction, that is, along the horizontal length of the top cover. The slot is arranged at the end position of the first direction, and the slot opening is aligned with the first slot 3. When moving back and forth along the first direction, the locking part 6 in the locking member 5 is located in the first slot 3, and moves back and forth horizontally in the first slot 3 to switch between the separation and locking states. If the locking member 5 moves horizontally to the left, the locking part 6 locks with the external slot; otherwise, when it moves to the right, the locking part 6 separates from the external slot. Thus, the switching between the locking and separation states of the locking part 6 and the slot is achieved by the horizontal movement.

[0059] Furthermore, such as Figure 2 As shown, to ensure the locking effect of the locking component 5, at least one buckle 15 is provided on the side of the cover 1 away from the locking component 5. The buckle 15 is engaged with the box body. When the locking component 5 is locked with the box body, the buckle 15 on the other side is engaged and fixed with the box body. By engaging and fixing both sides of the cover 1 with the box body, the locking of the top cover and the box body is kept stable. Even if a handle 12 is provided on the cover 1, the entire box body and the top cover can be easily lifted.

[0060] Therefore, a cover plate 2 is provided on the top cover of the box to form a receiving cavity, and the locking part 5 is located in the receiving cavity. Compared with the exposed part on the outside of the box, the overall structure is less prone to scratch damage. Moreover, the overall structure is simple, with fewer parts and less space occupied, resulting in high production and assembly efficiency. The locking structure can be realized by the two parts of the locking part 5 and the cover plate 2 on the basis of the cover 1. The locking part 6 on the locking part 5 can be locked and fixed by cooperating with the slot on the box. The locking part 5 slides in the receiving cavity and can be locked and separated by pushing and pulling. The operation is simple. Moreover, the locking structure is located on the cover 1, and the unlocking and locking can be completed while holding the cover 1, which can be operated quickly with one hand.

[0061] To facilitate the user's movement of the locking member 5 along the first direction, a second slot 4 communicating with the outside is provided on the accommodating cavity. The second slot 4 is located at the top of the accommodating cavity, specifically on the cover 1. The locking member 5 is provided with a push button 7 accommodated in the second slot 4. The operator can push the locking member 5 by contacting the push button 7 through the second slot 4. The push button 7 is integrally formed with the locking member 5. Pushing the push button 7 can drive the locking member 5 to reciprocate along the first direction. The movement of the locking member 5 along the first direction is achieved by pushing the push button 7, which is convenient and quick.

[0062] To limit the range of movement of the locking member 5 in the first direction, the inner diameter of the accommodating cavity in the first direction is greater than the length of the locking member 5 in that direction. The locking member 5 can reciprocate in the accommodating cavity along the first direction, thereby limiting the range of reciprocating movement of the locking member 5 in the first direction through the accommodating cavity.

[0063] The inner diameter of the receiving cavity is set to be greater than the length of the locking member 5. The locking member 5 can reciprocate in the receiving cavity along the first direction. The inner diameter of the receiving cavity in the first direction ensures that the locking member 5 can cooperate with the slot at the beginning and end of the stroke to achieve separation and locking. The receiving cavity serves to limit the reciprocating movement of the locking member 5 to the extreme position. When the locking member 5 moves to the end of the stroke, the locking part 6 can match and lock with the slot. When the locking member 5 moves to the beginning of the stroke, the locking part 6 can separate from the slot.

[0064] Similarly, to ensure that the push button 7 moves smoothly and unobstructed in the second slot 4, the inner diameter of the second slot 4 along the first direction is greater than the length of the push button 7 in that direction. In the first direction, the range of motion of the push button 7 in the second slot 4 is not greater than the range of motion of the locking member 5 in the receiving cavity, so as to ensure that the cooperation between the push button 7 and the second slot 4 does not affect the movement of the locking member 5 in the receiving cavity.

[0065] like Figure 3-5 As shown, specifically, to ensure the stability of the displacement of the locking member 5 in the first direction, it can be achieved by limiting groove 8 and limiting rib 9. One of the limiting groove 8 and limiting rib 9 is provided on the inner side wall of the accommodating cavity along the first direction, and the other is provided on the locking member 5. The limiting rib 9 slides and matches in the limiting groove 8.

[0066] Specifically, the upper limit groove 8 or the limiting rib 9 on the inner sidewall of the accommodating cavity can be located on the cover plate 2 and / or the cover body 1. That is, one of the limiting groove 8 and the limiting rib 9 can be provided on the cover body 1, one of the limiting groove 8 and the limiting rib 9 can be provided on the cover plate 2, or one of the limiting groove 8 and the limiting rib 9 can be provided on both the cover body 1 and the cover plate 2. Then, the other of the limiting groove 8 and the limiting rib 9 can be provided on the locking member 5. By providing mutually matching limiting groove 8 and limiting rib 9 between the locking member 5 and the accommodating cavity, the reciprocating movement of the locking member 5 is restricted by the limiting groove 8. The limiting groove 8 is arranged along the first direction, and the locking member 5 can ensure the accuracy of movement when it is moved under force.

[0067] In this embodiment, to ensure that the locking member 5 can remain in the end position after moving along the first direction, it also includes a first limiting mechanism 10 and two second limiting mechanisms 11. The two second limiting mechanisms 11 are spaced apart at both ends of the first limiting mechanism 10 along the first direction. When the first limiting mechanism 10 contacts and cooperates with the second limiting mechanisms 11 at both ends, it can play a locking and limiting role.

[0068] Specifically, when the first limiting mechanism 10 and the second limiting mechanisms 11 at both ends are in contact and cooperate with each other, they are used to limit the locking member 5 to the end of the stroke and the beginning of the stroke along the first direction. The cooperation between the first limiting mechanism 10 and the second limiting mechanisms 11 at both ends achieves the fixation of the locked state and the fixation of the separated state.

[0069] One of the first limiting mechanism 10 or the second limiting mechanism 11 is disposed on the locking member 5. If the first limiting mechanism 10 is disposed on the locking member 5, then the two second limiting mechanisms 11 are disposed on other components at both ends of the locking member 5, such as the cover plate 2. If two spaced-apart second limiting mechanisms 11 are disposed on the locking member 5, then the first limiting mechanism 10 is disposed on other components located between the two second limiting mechanisms 11.

[0070] By utilizing the first limiting mechanism 10 and the second limiting mechanism 11 that cooperate with each other, it is possible to ensure that the locking member 5 is in a locked state or a disengaged state with the housing. The two second limiting mechanisms 11 are located at both ends of the first limiting mechanism 10, which ensures that the locking member 5 is restricted in the locked state and will not easily disengage from the locked state. At the same time, it also ensures that the locking member 5 is restricted in the disengaged state and will not easily disengage from the locked state. This ensures the stability of the locking member 5 at both ends of its stroke, so that the locking member 5 can be stably maintained in the locked state and the disengaged state.

[0071] Specifically, in one embodiment, the first limiting mechanism 10 and the second limiting mechanism 11 are mutually attracting magnetic components, that is, the first limiting mechanism 10 is a first magnetic component and the second limiting mechanism 11 is a second magnetic component. The first magnetic component located in the middle can be embedded in the locking component 5, and the two second magnetic components located at both ends can be located on the cover plate 2 or on the inner wall of the accommodating cavity, etc., at the two ends of the first magnetic component spaced apart along the first direction. They are mainly used to attract and fix each other when the first magnetic component approaches any of the second magnetic components, thereby limiting the locking component 5 at the end of the stroke and the beginning of the stroke, so as to maintain the locked state and the separated state of the locking component 5. The magnetic components are embedded in the locking component 5 and other components, which are not shown in the figure.

[0072] To ensure that the attraction between the first magnetic component and the two second magnetic components does not interfere with each other, the effective magnetic force distance between two adjacent magnetic components is less than the actual distance between them. That is, the first magnetic component located at the center point between the two second magnetic components needs to move a certain distance along the first direction before the first magnetic component and the second magnetic component enter each other's effective magnetic force distance and then they will attract each other through magnetic force.

[0073] The effective magnetic force range is defined as the attraction between two magnetic components when the actual distance between them is less than this range. The effective magnetic force range can be determined by the formula relating magnetic attraction and distance, which is a standard formula and will not be elaborated here. The specific range can be controlled by selecting the size and strength of the magnetic components.

[0074] In this embodiment, a handle 12 is provided on the cover 1. In order to save the assembly process and improve the assembly efficiency, the handle 12 is integrally formed with the cover 1. The handle 12 forms a gripping part 13 on the cover 1 by protruding outward and / or concave in a preset deformation direction.

[0075] Specifically, the deformation direction of the handle 12 can be perpendicular to the surface of the cover 1 to form an outwardly protruding gripping part 13;

[0076] Alternatively, a concave space can be formed inward along the surface perpendicular to the cover 1, and the concave space can be used to allow fingers to be inserted to form a gripping part 13 when combined with the cover 1;

[0077] Alternatively, the outward convex deformation can be combined with the inward concave deformation to form a larger space, with the middle hollowed out and connected. The outward convex and inward concave deformations form a gripping part 13 with a larger space, making it easier for fingers to insert while retaining space for the palm to lift.

[0078] like Figure 2 , 4 As shown, in order to ensure that the palm can hold it more easily, the edge of the grip portion 13 of the handle 12 is provided with at least one anti-slip rib 14 to prevent the user from slipping due to instability.

[0079] The one-piece molded handle 12 effectively enhances the ergonomics of the product, reducing the traditional cumbersome assembly process and lowering the company's costs.

[0080] Example 2

[0081] Unlike Embodiment 1, the first limiting mechanism 10 and the second limiting mechanism 11 in this embodiment are specifically as follows:

[0082] like Figure 3 , 4As shown in Figure 5, the first limiting mechanism 10 is one of a mutually matching gear slot or gear block, and the second limiting mechanism 11 is the other one. If the first limiting mechanism 10 is a gear slot, then the two second limiting mechanisms 11 are two gear blocks. If the first limiting mechanism 10 is a gear block, then the two second limiting mechanisms 11 are two gear slots.

[0083] Since one of the first limiting mechanism 10 and the second limiting mechanism 11 needs to be installed in the locking member 5, the other needs to be installed in the cover plate 2. As long as the first limiting mechanism 10 can cooperate with the second limiting mechanism 11, the correspondence between the first limiting mechanism 10 or the second limiting mechanism 11 and the locking member 5 is not restricted.

[0084] In this embodiment, the first limiting mechanism 10 is set as a stop block and is disposed in the cover plate 2, and the second limiting mechanism 11 is set as two stop grooves and is disposed in the locking member 5. When the two stop grooves in the locking member 5 respectively contact and engage with the stop block, the locking member 5 is located at the end of the stroke and the beginning of the stroke respectively, so as to maintain the locking state and the disengaged state of the locking member 5.

[0085] Specifically, to reduce the wear of the stop groove and the stop block, a deformation strip 16 is provided on the cover plate 2 along the first direction. One of the first limiting mechanism 10 or the second limiting mechanism 11 is provided on the deformation strip 16 of the cover plate 2. Specifically, the stop block is located in the deformation strip 16. The elasticity of the deformation strip 16 is used to achieve an interference fit between the stop block and the stop groove, thereby ensuring the stability of the card swipe connection. Specifically, the deformation strip 16 is achieved by deformation holes on both sides of the deformation strip 16 starting along the first direction.

[0086] Everything else is the same as in Example 1, and will not be repeated here.

[0087] Example 3

[0088] This embodiment also discloses a toolbox, which includes the top cover and box body as in embodiment 1. The box body is provided with a slot that matches the snap-fit ​​part 6. The top cover fits and closes onto the opening of the box body. The first slot 3 on the top cover is aligned with the slot. The locking member 5 can lock with the box body by cooperating with the slot. The specific locking effect is described in embodiment 1 and will not be repeated here.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
