Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a dental material storage box. Background Technology

[0002] Dental materials are materials used to treat patients' teeth. There are many types of dental materials, such as bottled materials, forceps, and syringes. These materials are often placed on the treatment cart's work surface during use, and frequent handling can easily make the work surface cluttered.

[0003] Currently, to keep the treatment cart surface tidy, storage boxes are typically used to hold dental materials. However, existing storage boxes usually have a fixed shape and structure during manufacturing, often resulting in the need to stack dental materials. For example, for instruments with handles such as tweezers, cotton swabs, and syringes, although they are organized by function, instruments with the same function are often piled up in a way that easily leads to overlapping and confusion, requiring one to rummage through them to find them. Bottled items also tend to be piled up, easily obstructing the view of medical staff when retrieving them, and requiring the removal of the top bottles before accessing the bottom ones. These operations not only cause inconvenience and chaos but also prolong surgical time. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a dental material storage box that can separate different types of dental materials and prevent confusion when taking them out.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] A dental material storage box includes a box body with an open top and front side. The upper middle part of the box body has a main cavity with an open top. A secondary cavity with an open top is located on each of the left and right sides of the main cavity. The bottom of the main cavity is lower than the secondary cavities. Each secondary cavity has an adjustable, offset cavity with an open top. The lower middle part of the box body has a drawer. The top of the drawer matches the bottom of the main cavity and secondary cavities. The drawer contains a divider.

[0007] The top of the box is provided with an openable cover assembly, which includes a top plate. The bottom surface of the top plate has several snap-fit ​​grooves, and detachable clamping parts are installed in the several snap-fit ​​grooves. The top surface of the top plate is provided with a limiting mechanism for adjusting the opening angle of the cover assembly.

[0008] The main cavity is used to store some dental instruments, the secondary cavity is used to store some flat items, the drawer is used to store some bottled medicines, and the clamps on the top plate are used to hold some pliers such as syringes, tweezers, and adhesives and resins contained in syringes.

[0009] In some embodiments, the front and rear end faces of the movable cavity are respectively provided with vertical guide grooves, the bottom surface of the guide grooves being lower than the bottom surface of the movable cavity. A guiding component is provided within the guide groove, extending obliquely downwards to above the bottom of the secondary cavity and hinged to the inner wall of the secondary cavity. This addresses the problem of how to achieve smooth and stable movement and positioning of the movable cavity.

[0010] In some embodiments, the side of the sub-cavity is provided with a clearance groove for the guide component to swing, and the clearance groove is connected to the outer wall of the housing to ensure that the guide component does not interfere with the side wall of the sub-cavity during movement.

[0011] In some embodiments, the snap-fit ​​groove includes a rectangular recess, and the inner wall of the recess has baffles on the left and right sides, with the front ends of the baffles terminating at the middle of the inner wall of the recess.

[0012] Further extending the above solution, the clamping member includes an arc-shaped clamping end, the top of which is provided with a snap-fit ​​block that matches the area between the countersunk groove and the retaining edge of the snap-fit ​​groove. This enables the clamping member to be quickly installed and removed, and to securely engage with the snap-fit ​​groove.

[0013] In some embodiments, the limiting mechanism includes a guide rod and a snap-fit ​​component. The guide rod is annular and its ends are not connected. The tail end of the guide rod is fixedly connected to the upper middle part of the rear end face of the box. A plurality of equally angled slots are provided on the annular surface of the guide rod. A through hole is provided on the top surface of the top plate for the front end of the guide rod to pass through. The snap-fit ​​component is located on the top of the top plate.

[0014] Further expanding upon the above solution, the locking component includes two equidistant fixing blocks, aligned longitudinally with the guide rod. A telescopic rod capable of sliding back and forth is mounted on the two fixing blocks, and a spring is sleeved on the telescopic rod, positioned between the two fixing blocks. A limiting piece is also provided at the rear end of the spring and on the telescopic rod. A claw is provided at the front end of the telescopic rod, and a limiting block for extending into any locking slot is provided at the rear end. This provides a convenient and automatically locking limiting mechanism.

[0015] In some embodiments, the front side of the box body is provided with a front baffle that swings laterally around the bottom of the front side of the box body. This prevents the drawer from slipping off the box body.

[0016] Compared to existing technologies, this application achieves at least the following beneficial effects: This storage box, by setting a main cavity and a secondary cavity on the box body, allows for the partitioning and storage of materials of different volumes or frequencies of use. A movable cavity is installed in the secondary cavity to lay frequently used items flat, reducing the stacking of items or instruments. The drawer at the bottom of the box can be used to classify and store medicines in bottles and jars of varying heights, reducing stacking. Users can fix forceps and certain medicines to the top panel using a snap-fit ​​mechanism, allowing for easy viewing and retrieval upon opening the storage box. In summary, this storage box rationally distinguishes different types or functions of items or instruments, allowing medical staff to intuitively see what items or instruments are stored in each area, thus solving the problem of chaotic placement and retrieval to a certain extent. When medical staff can quickly and accurately retrieve various items or instruments, this also improves surgical efficiency. Attached Figure Description

[0050] The present application will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0051] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0052] To address the shortcomings of existing technologies, such as the tendency for instruments and items placed on the treatment cart surface to become disorganized and inconvenient to access, the inventors, after careful analysis, discovered that the main reason for this problem lies in the current practice of using storage boxes to hold various dental materials in order to keep the treatment cart surface tidy. However, because existing storage boxes are often designed with fixed shapes and structures, they lack adaptability to the characteristics of various instruments and items, resulting in dental materials often being stored in a stacked manner in actual use.

[0053] This stacking method not only failed to fundamentally solve the problem of space utilization efficiency, but also caused new operational problems, specifically in the following aspects:

[0054] First, for instruments with handles such as tweezers, cotton swabs, and syringes, although the storage boxes are functionally divided on the surface, the size and depth of each compartment or area are not designed for the length, thickness, and frequency of use of different instruments. This means the instruments cannot be kept upright or arranged in an orderly manner when placed inside. Especially when there are many of the same type of instrument, they can only be stacked and intertwined, forming a pile. When medical staff urgently need a particular instrument, they often have to rummage through the layers and search repeatedly, which not only easily disrupts the position of other instruments but also increases the time cost of finding the target item.

[0055] Secondly, bottled items such as medicines and disinfectants also present similar problems. Because the storage boxes lack a reasonable three-dimensional or tilting design, bottles and jars can only be stacked horizontally. Containers on the lower layers are obscured by those on top, making it difficult to quickly identify labels, types, or remaining quantities. When items at the bottom need to be retrieved, the bottles and jars on the upper layers must be removed one by one. This process is not only cumbersome but can also easily lead to confusion during surgery, and may even cause bottles to tip over or become contaminated due to improper temporary placement.

[0056] It is evident that although the purpose of using storage boxes is for tidiness and partitioning, the fixed structural design cannot adapt to diverse clinical usage scenarios. Instead, the items and instruments become difficult to access quickly due to stacking and interleaving, ultimately slowing down the pace of diagnosis and treatment and prolonging the operation time.

[0057] Based on the above analysis, the inventors made structural improvements to existing storage boxes or organizers.

[0058] like Figure 1-10 As shown, in at least one embodiment of the oral material storage box of this application, a rectangular box body 1 is included, the size of which is adapted to the size of the treatment cart table. The top and front of the box body 1 are open. The box body 1 has a hollow structure, and a base plate is fixedly connected to the upper middle part of its interior. The middle part of the base plate is lower than the left and right sides, forming an inverted convex structure from the main viewing angle. A baffle matching its structure is fixedly connected to the front end of the base plate. A longitudinally arranged partition plate 1101 is fixedly connected to the left and right sides of the top of the base plate, respectively. The rear ends of the base plate and the partition plate 1101 are fixedly connected to the rear end inside the box body 1. The partition plate 1101 divides the base plate into three areas. The middle area of ​​the base plate is the main cavity 60, and the left and right sides are the secondary cavities 70. The top surfaces of the main cavity 60 and the secondary cavities 70 are flush, and the bottom of the main cavity 60 is lower than the secondary cavities 70. The secondary cavity 70 has an adjustable movable cavity 80 that is offset from it, and the top of the movable cavity 80 is open. A drawer 110 is installed in the lower middle cavity of the box body 1. The top of the drawer 110 matches the bottom of the main cavity 60 and the secondary cavity 70, forming a structure that is higher on both sides and lower in the middle. Vertically arranged partition plates 1101 are installed on the left and right sides of the drawer 110, dividing the interior of the drawer 110 into three spaces corresponding to the main cavity 60 and the secondary cavity 70. A notch is provided in the center of the top surface on the front side of the drawer 110 for easy pulling out by medical personnel. The above fixed connections can be made by adhesive bonding or welding.

[0059] The top of the box body 1 is equipped with an opening and closing cover assembly. The cover assembly includes a top plate 20, which matches the opening at the top of the box body 1. The rear end of the top plate 20 is connected to the rear end of the box body 1 by a hinge 2, allowing the top plate 20 to open upwards. Specifically, the middle of the upper blade of the hinge 2 is bent forward, and the bent part is riveted to the top surface of the rear end of the top plate 20. The lower blade of the hinge 2 is bent toward the rear end face of the box body 1, and the front end face of the lower blade is fitted with the rear end face of the box body 1, and the connection is made by riveting. The bottom surface of the top plate 20 (facing inwards towards the box body 1) has several locking grooves, and clamping parts 120 are detachably installed in the locking grooves. A limiting mechanism for adjusting the opening angle of the cover assembly is installed on the top surface of the top plate 20.

[0060] The box 1 is designed with openings on the top and front, allowing for access to items from multiple directions. The main cavity 60 and secondary cavity 70, with varying depths, allow for the separate storage of materials of different sizes or frequencies. The movable cavity 80 prevents small items in the secondary cavity 70 from stacking. The bottom drawer 110 can store bottles and jars of medicine of different sizes or heights, complementing the clamping parts 120 on the top panel 20 and maximizing the use of the overall space of the box 1.

[0061] The function of the movable cavity 80 is to divide the auxiliary cavity 70 into layers, reducing the need for stacking thin medical items such as cotton swabs and catheters. Figure 2 , 7 and Figure 8 As shown, the movable cavity 80 is a rectangular hollow structure made of plastic with an open top, and it is fitted into the upper middle part of the sub-cavity 70 with a clearance fit. A vertical guide groove 90 is fused to the front and rear end faces of the movable cavity 80. The guide groove 90 is made of a rectangular metal or plastic strip connected end to end, and its top and bottom can be rounded. The top of the guide groove 90 is located in the upper middle part of the movable cavity 80, and the bottom extends downward to the bottom surface of the movable cavity 80, so that the two guide grooves 90 have the function of supporting the movable cavity 80 in the upper middle part of the sub-cavity 70. A guide component 100 is provided inside the guide groove 90. The guide component 100 is strip-shaped, and its other end extends obliquely downward to the connection between the sub-cavity 70 and the box body 1, and is located above the bottom of the sub-cavity 70. Figure 8 As shown, horizontally arranged strip-shaped adjustment grooves 13 are respectively provided on the rear end face of the box body 1 and the rear end face of the baffle. The other end of the guide component 100 extends into the adjustment groove 13 to form a hinge.

[0062] Simply lifting the movable cavity 80 may be unstable or prone to jamming. By setting a vertical guide groove 90 and a guide component 100, the movement of the movable cavity 80 is guided and constrained. The guide component 100 extends obliquely downward and is hinged to the secondary cavity 70 through the adjustment groove 13, forming a stable linkage or guide rail mechanism, ensuring that the trajectory of the movable cavity 80 is controllable during movement and can smoothly stop at the desired position.

[0063] To allow the guide component 100 to swing outwards from the box 1, thereby moving the movable cavity 80 away from the sub-cavity 70, a clearance groove 11 is provided on the side of the sub-cavity 70 for the guide component 100 to swing. The bottom surface of the clearance groove 11 is flush with the bottom surface inside the sub-cavity 70, and the clearance groove 11 is connected to the outer wall of the box 1. (Reference) Figure 8The guiding assembly includes a rectangular, flat, swing rod 1002. A cylindrical first slider 1001 is located at the rear of the top end of the swing rod 1002. In a stationary state, the first slider 1001 is positioned at the top of the guide groove 90. A gap exists between the first slider 1001 and the guide groove 90. A cylindrical second slider 1003 is located at the rear of the bottom end of the swing rod 1002. The second slider 1003 is located within an adjusting groove 13, thus forming a hinge. The bottom of the adjusting groove 13 is not coplanar with the inner wall of the clearance groove 11 to prevent the guiding component 100 from dislodging from the clearance groove 11. Figure 3 As shown, when the movable cavity 80 is pulled upward, due to the gap between the first slider 1001 and the guide groove 90, the guide groove 90 will not cause the guide assembly to swing during the upward movement until the bottom surface of the movable cavity 80 leaves the top surface of the sub-cavity 70. Then, the guide component 100 swings towards the side of the box 1, causing the movable cavity 80 to move (if the movable cavity 80 is in the left sub-cavity 70, it moves to the left; if the movable cavity 80 is in the right sub-cavity 70, it moves to the right). This continues until the movable cavity 80 moves to the side of the box 1, causing the second slider 1003 to move outward to the end point of the adjustment groove 13 facing the outside of the box 1 (the purpose is to make the movable cavity 80 avoid the side of the box 1 so that the movable cavity 80 can move downward). Then, the movable cavity 80 moves downward so that the top surface of the guide groove 90 contacts the first slider 1001. At this time, the side of the movable cavity 80 facing the box body 1 is attached to the side of the box body 1. By limiting the end face attachment, the movable cavity 80 is prevented from rotating, thus preventing the items inside the movable cavity 80 from falling out.

[0064] like Figure 4 As shown, the snap-fit ​​groove includes a rectangular recess, and the left and right sides of the inner wall of the recess are respectively provided with a retaining edge protruding into the recess. The front end of the retaining edge terminates at the middle of the inner wall of the recess, so that the snap-fit ​​groove has an inverted convex structure.

[0065] Clamping component 120 is made of plastic, see reference. Figure 4 and Figure 10The clamping member 120 includes an arc-shaped clamping end 1201 (refer to a broom clip). The top of the clamping end 1201 has a clamping block 1202 that matches the area between the recess and the retaining edge of the clamping groove. The left and right sides of the top of the clamping block 1202 have protruding flanges 1203. The rectangular recess provides the main receiving space, while the retaining edge forms a snap-fit ​​structure. By restricting the upward movement of the clamping block 1202, the clamping member 120 is fixed. When the clamping block 1202 of the clamping member 120 is inserted into the recess, and then the clamping member 120 is pushed backward, the clamping block 1202 and the flanges 1203 are pushed into the space between the retaining edge and the recess. At this point, the flanges 1203 on the clamping block 1202 are restricted and will not fall out of the clamping groove. When the top plate 20 is opened upwards, the snap-fit ​​block 1202 is restricted by the flange 1203 and will not fall out of the snap-fit ​​groove. When the top plate 20 is closed, it is blocked by the top surface of the box 1 and will not tilt. Therefore, the clamping member 120 will not slide forward and disengage in the snap-fit ​​groove.

[0066] The clamping slots are longitudinally provided with several clamping slots. The clamping end 1201 can be installed in the corresponding clamping slot according to the length of the clamping instrument, so that clamping instruments or items of different lengths of pliers can be used.

[0067] A limiting mechanism is used to restrict the top plate 20 to a specific angular position after it is opened. This limiting mechanism includes a guide rod 3 and a locking element. The guide rod 3 is annular and its ends are not connected. The guide rod 3 can be made of metal or rigid plastic, either round or square. A square fixing plate is welded or fused to the tail end of the guide rod 3, and is riveted to the upper middle part of the rear end face of the box body 1 via the fixing plate. Several equally angled locking grooves 31 are formed on the annular surface of the guide rod. A through hole is formed on the top surface of the top plate 20 for the front end of the guide rod 3 to pass through. When the top plate 20 is opened, it flips upwards along the guide rod 3.

[0068] The snap-fit ​​component is installed on the top of the top plate 20. This snap-fit ​​component includes two rectangular fixing blocks 6 evenly spaced front to back. The two fixing blocks 6 are bonded to the top plate 20 and longitudinally aligned with the guide rod 3. A coaxial through hole is formed on the front end face of each fixing block 6. A telescopic rod 7 that can slide back and forth is installed within the two through holes. A spring 5 is sleeved on the telescopic rod 7 and located between the two fixing blocks 6. A circular limiting piece 71, with a diameter larger than that of the spring 5, is also sleeved and welded onto the rear end of the spring 5 and the telescopic rod 7. The rear end of the spring 5 abuts against the limiting piece 71, and the front end abuts against the rear end face of the front fixing block 6.

[0069] The telescopic rod 7 has a claw at its front end. The claw structure includes a rectangular paddle 8, which is vertically arranged and welded to the front end of the telescopic rod 7. A rectangular connecting piece 9, arranged longitudinally, is welded to the front end of the left and right sides of the paddle 8. The bottom of the paddle 8 and the connecting piece 9 are in contact with the top surface of the top plate 20. The front ends of the two connecting pieces 9 are bent downwards and then backwards to form a groove hook 10. A rectangular limiting block 50, which can extend into any slot 31, is welded to the rear end of the telescopic rod 7. The thickness of the limiting block 50 matches the width of the slot 31. When the top plate 20 covers the top surface of the box 1, the limiting block 50 presses against the arc surface of the guide rod 3. At this time, there is a large gap between the rear end face of the limiting piece 71 and the fixing block 6. The limiting piece 71 pushes the spring 5 forward to compress it. When the top plate 20 is opened upwards, the limiting block 50 slides along the arc surface of the guide rod 3 until it is engaged in the slot 31. When adjusting the opening angle of the top plate 20, first pry open the lever 8 of the pawl to make the sliding rod move the limiting piece 71 forward. The spring 5 is compressed, and at this time the limiting block 50 leaves the slot 31. Flip the top plate 20 backward until the appropriate angle is reached. Then release the lever 8 and adjust the angle of the top plate 20 so that the limiting block 50 is inserted into the nearest slot 31. The spring 5 pushes the limiting piece 71 closer to the fixing block 6 on the rear side, fixing the limiting block 50 in the slot 31.

[0070] A front baffle 30, which can be opened forward, is hinged to the bottom front side of the box body 1. A forward-facing flange 301 is provided on the front front side of the top face of the front baffle 30. The inner side of the slotted hook 10 of the latch engages with the front end face of the flange 301, thereby restricting the opening of the front baffle 30. Specifically, the front baffle 30 is connected to the front side of the box body 1 by fusing or welding a semi-circular connecting plate 40 to the front side of each of the left and right side walls of the box body 1. The bottom edge of the connecting plate 40 is flush with the bottom surface of the box body 1. An arc-shaped groove 401 is provided on the inner side of the connecting plate 40. A cylindrical protrusion is provided on the lower middle part of each of the left and right sides of the front baffle 30, and these two protrusions are respectively located within the arc-shaped grooves 401 of the two front baffles 30. When the latch is released, the protrusions on the baffles can slide along the arc-shaped grooves 401, causing the baffle to open forward.

[0071] To prevent contact with the snap-fit ​​parts, a grooved cover 4 is glued to the top surface of the top plate 20 on the outside of the snap-fit ​​parts, covering the two fixing blocks 6 and the telescopic rod 7 between them.

[0072] A cylindrical sliding block is welded to the rear side of each of the left and right end faces of drawer 110. Vertically distributed limiting grooves 12 are respectively formed on the left and right sides of the inner wall of box 1, and the sliding blocks are located within the limiting grooves 12. When drawer 110 is pulled forward until the sliding block contacts the front end face within the limiting groove 12, it prevents the drawer 110 from being completely pulled out of box 1 when a large pulling force is applied.

[0073] The main cavity is 60mm deep, making it suitable for placing taller items; the secondary cavity is 70mm shallow, making it suitable for placing flat items.

[0074] When using the movable cavity 80, lift it upwards by hand until its bottom surface is completely away from the top surface of the secondary cavity 70. Then, swing the movable cavity 80 to the side of the box 1 (left movable cavity 80 to the left, right movable cavity 80 to the right), at which point the guide component 100 will swing accordingly. Once you feel the movable cavity 80 has moved into place, move it downwards a short distance until the guide groove 90 abuts against the first slider 1001. At this point, the movable cavity 80 is stably fixed to the side of the box 1, and the lower space of the secondary cavity 70 is fully exposed. To close the movable cavity 80, gently lift it upwards to release it from its limit position. Swing the movable cavity 80 towards the center of the box 1 to move it back to directly above the secondary cavity 70. Finally, lower it back into the secondary cavity 70.

[0075] To use drawer 110, insert your finger into the notch on the front of drawer 110 and pull drawer 110 forward to retrieve or place bottles or jars. Push drawer 110 back to close it.

[0076] When using the cover assembly, lift the top plate 20 upwards by hand. The top plate 20 will automatically engage in the first forward-facing slot 31 on the guide rod 3 under the action of the limiting mechanism. To adjust the angle, use your finger to pry the lever 8 on the claw. Continue lifting the top plate 20 to the desired angle, then release the lever 8. The limiting block 50 will automatically engage in the nearest slot 31. A "click" sound indicates that the limiting block 50 is engaged in the slot 31, thus fixing the angle.

[0077] When installing the clamping component 120, align the snap-fit ​​block 1202 of the clamping component 120 with any of the snap-fit ​​grooves on the bottom surface of the top plate 20 and insert it. Then push the clamping component 120 backward until the snap-fit ​​block 1202 and the flange 1203 slide under the stop bar, indicating that it is in place. When removing the clamping component 120, slide the clamping component 120 forward to release the snap-fit ​​block 1202 from the stop bar, and it can then be removed from the groove.

[0078] When the front panel 30 is opened, the paddle 8 of the chuck is operated to disengage the slotted hook 10 from the retaining edge 301 of the front panel 30. The front panel 30 can then be opened by gravity or by manually flipping it forward, providing a passage for storing and retrieving items from the front.

[0079] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
