Description

Technical Field

[0001] This utility model relates to the field of drawer technology, specifically to an anti-detachment drawer for a laboratory table. Background Technology

[0002] Drawers, as components attached to furniture such as tables and cabinets, are usually in the form of pull-out boxes for storing things. Drawers can be used to store loose items, preventing too many loose items from being exposed in the space and making the space cluttered. At the same time, drawers have good privacy and dust protection properties.

[0003] In laboratories, drawers often store items with significantly different densities, and the degree to which these drawers can be opened needs to be restricted for different items.

[0004] Chinese patent CN213487852U discloses an anti-fall-off drawer, which is used to prevent the drawer from falling off.

[0005] However, the above-mentioned publicly available solutions have the following shortcomings: In actual use, the maximum extent to which the drawer can be pulled out cannot be adjusted, thus making it impossible to control and adjust the maximum extent to which the drawer can be pulled out according to the weight of the items actually stored in the drawer, thereby increasing the risk of the drawer's overall structure tipping over.

[0006] This invention proposes an anti-detachment drawer for an experimental table to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to limit the maximum extent to which a drawer can be pulled out by means of a sliding adjustable stop block, thereby preventing the overall structure from tilting due to a shift in the center of gravity of the drawer. The sliding adjustable stop block can be adjusted according to the weight of the items stored in the drawer, thereby overcoming the problems mentioned in the background art.

[0008] Based on the above technical concept, the technical solution adopted by this utility model is as follows: An anti-detachment drawer for a laboratory bench includes a housing and a storage compartment. An opening is provided on one side of the housing. A sliding component is fixedly connected to the top of the inner wall of the housing. The sliding component includes a sliding rail fixedly connected to the top of the inner wall of the housing. A sliding plate is slidably connected to the center of the bottom of the sliding rail. The bottom of the sliding plate is fixedly connected to both sides of the top of the storage compartment. A limiting component is provided on the side of the storage compartment away from the opening of the housing. The limiting component is used to prevent the storage compartment from sliding. An adjusting component is provided at the bottom of the sliding rail. The adjusting component includes a blocking block for blocking the sliding plate and a fastener for fixing the blocking block. A storage component for securing items is provided inside the storage compartment.

[0009] Further defining the above technical solution, the limiting component includes a limiting groove disposed on the side of the housing away from the opening, a limiting ring fixedly connected to the side of the storage compartment away from the opening of the housing, the limiting ring passing through the inside of the limiting groove, and a blocking component fixedly connected to the outer side of the housing for blocking the limiting ring. The combination of the limiting ring and the subsequent blocking spring can block the storage compartment from being pulled out, thereby preventing the storage compartment from accidentally sliding open automatically.

[0010] Further defining the above technical solution, the blocking assembly includes a limiting cavity fixedly connected to the outer side of the housing. The limiting cavity is sleeved above the limiting through groove. A mounting base is fixedly connected to the outer side of the housing. The mounting base is symmetrically arranged on both sides of the limiting through groove. A connecting bolt is threaded onto the mounting base. A blocking spring is provided on the side of the mounting base away from the housing. The blocking spring has rings at both ends. The connecting bolt passes through the rings at both ends of the blocking spring. The blocking spring is curved and contacts the outer arc surface of the limiting ring. The blocking spring fixed by bolts can be easily replaced after the blocking spring suffers metal fatigue, thereby ensuring a stable blocking effect on the storage compartment.

[0011] Further defining the above technical solution, the sliding track is inverted U-shape, the sliding plate is T-shaped, and rotating brackets are symmetrically provided on both sides of the sliding plate. Rollers are rotatably connected to the bottom of the rotating brackets. The width of the rollers is greater than the width of the adjusting groove. The rollers contact the bottom of the inner wall of the sliding track. A pressing component for pressing the sliding plate is provided inside the sliding track. The contact between the rollers and the sliding track reduces the sliding resistance of the structure and reduces the frictional loss between the sliding plate and the sliding track.

[0012] Further defining the above technical solution, the pressing component includes a mounting groove disposed on the side of the housing away from the opening, a limiting plate is provided on the inner wall of the mounting groove, a docking groove is provided at the end of the limiting plate away from the mounting groove, the limiting plate is disposed inside the sliding track, and the bottom of the limiting plate is slidably docked with the top of the sliding plate.

[0013] Further defining the above technical solution, the adjusting component also includes an adjusting groove disposed at the bottom of the sliding track. A connecting bolt is slidably connected to the inner wall of the adjusting groove, and a washer is sleeved on the outer arc surface of the connecting bolt. The washer contacts and presses against the outer side of the bottom of the sliding track. A blocking block is threadedly connected to the connecting bolt. By combining the connecting bolt and the blocking block, the position of the moving blocking block can be adjusted inside the adjusting groove, thereby controlling the maximum degree of extraction of the storage compartment and facilitating targeted adjustment according to the weight of the items inside the storage compartment.

[0014] Further defining the above technical solution, the blocking block is disposed inside the sliding track, and the side of the blocking block contacts and blocks the roller. The roller is symmetrically disposed at both ends of the sliding plate, and the sliding components are symmetrically disposed on both sides of the top of the inner wall of the housing. The storage hopper is U-shaped, and the sliding plates in the two sets of sliding components are fixedly connected to the top two ends of the storage hopper. The bottom of the outer side of the storage hopper slides in contact with the bottom of the inner wall of the housing. The use of symmetrical sliding components for sliding connection can make the force on the storage hopper more uniform and prevent the storage hopper from tilting.

[0015] Further defining the above technical solution, the docking groove is a waist-shaped groove, with the inner diameter of one end of the waist-shaped groove being larger than the inner diameter of the other end. An arc-shaped blocking block is provided at the top of the waist-shaped groove, positioned above the end with the smaller inner diameter. The storage component includes a limiting base fixedly connected to the bottom of the inner wall of the storage compartment. The top of the limiting base has several equally spaced, linearly distributed limiting protrusions. Symmetrical sliding grooves are provided on both sides of the limiting base. A sliding rod is slidably connected to the inner wall of the sliding groove. The width of the inner wall of the sliding groove is greater than the outer diameter of the sliding rod. The sliding rod is located away from the sliding groove. A sliding bracket is fixedly connected to the end, and a first limiting ring is fixedly connected to the center of the top of the sliding bracket. The sliding bracket is in the shape of an inverted U. A docking protrusion is provided on the sliding bracket directly below the first limiting ring. The docking protrusion contacts the limiting protrusion. Through the structure of the docking groove, a connecting rod with an I-shaped cross-section is inserted from the end with the larger inner diameter and then slid to the end with the smaller inner diameter to achieve a docking connection with the limiting plate. This makes it easier to pull the limiting plate out of the sliding track. By pulling out the limiting plate, the roller can pass over the blocking block from the top of the blocking member, thereby achieving the effect of taking out the storage compartment.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. By sliding and adjusting the position of the blocking block, the maximum extent to which the storage compartment can be pulled out can be limited, thereby preventing the overall structure from tilting due to excessive pulling out when heavy items are stored in the storage compartment. 2. The combination structure of the limiting ring and the blocking spring ensures that a certain pulling force is required to pull out the storage compartment, thus preventing the storage compartment from sliding freely and opening accidentally. 3. The use of rollers instead of traditional sliding friction structures for pull-pull sliding transmission reduces wear during relative sliding and extends the service life of this structure.

[0020] The present application will be further described in detail below with reference to the accompanying drawings. Reference Figure 2 and Figure 6This application discloses an anti-detachment drawer for a laboratory bench, comprising a housing 1 and a storage compartment 2. The housing 1 has an opening on one side. A baffle 3 is fixedly connected to the side of the storage compartment 2 near the opening of the housing 1. The width of the baffle 3 is greater than the width of the inner wall of the housing 1. An information panel 4 and a handle 5 are provided on the side of the baffle 3 away from the storage compartment 2. The application also includes a sliding component 7, which includes a sliding rail 701 fixedly connected to the top of the inner wall of the housing 1. A sliding plate 702 is slidably connected to the bottom of the sliding rail 701. The bottom of the sliding plate 702 is fixedly connected to the top two sides of the storage compartment 2. An adjustment component 8 is provided at the bottom of the sliding rail 701. The adjustment component 8 includes a blocking block 804 for blocking the sliding plate 702. A storage component 9 for fixing items is provided inside the storage compartment 2.

[0021] By blocking the sliding plate 702 with the blocking block 804, the storage drawer 2 can be prevented from being pulled out as a whole when it is pulled out, thus achieving the effect of preventing the drawer from falling off.

[0022] Reference Figure 3 and Figure 4 The limiting component 6 includes a limiting groove 602 disposed on the side of the housing 1 away from the opening. A limiting ring 603 is fixedly connected to the side of the storage compartment 2 away from the opening of the housing 1. The limiting ring 603 passes through the limiting groove 602. A limiting cavity 601 is fixedly connected to the outer side of the housing 1. A blocking component for blocking the limiting ring 603 is fixedly connected to the outer side of the housing 1. The blocking component includes the limiting cavity 601 fixedly connected to the outer side of the housing 1. The limiting cavity 601 is sleeved on the storage compartment 2. Above the limiting through groove 602, a mounting base 604 is fixedly connected to the outer side of the housing 1. The mounting base 604 is symmetrically arranged on both sides of the limiting through groove 602. The mounting base 604 is threadedly connected to a connecting bolt 606. A blocking spring 605 is provided on the side of the mounting base 604 away from the housing 1. The blocking spring 605 has rings at both ends. The connecting bolt 606 passes through the rings at both ends of the blocking spring 605. The blocking spring 605 is curved and contacts the outer arc surface of the limiting ring 603.

[0023] The structure of the limiting component 6 can generate resistance during the initial extraction process of the storage compartment 2, thereby preventing the storage compartment 2 from opening accidentally. At the same time, the blocking spring 605 blocks the limiting ring 603, preventing the storage compartment 2 from shaking inside the housing 1.

[0024] Reference Figure 5 and Figure 6The sliding track 701 is in the shape of an inverted U-shape, and the sliding plate 702 is in the shape of a T-shape. The sliding plate 702 is symmetrically provided with rotating brackets on both sides. The bottom of the rotating brackets is rotatably connected to a roller 705. The roller 705 contacts the bottom of the inner wall of the sliding track 701. The sliding track 701 is provided with a pressing component for pressing the sliding plate 702. The pressing component includes a mounting groove 706 provided on the side of the housing 1 away from the opening. The inner wall of the mounting groove 706 is provided with a limiting plate 703. The end of the limiting plate 703 away from the mounting groove 706 is provided with a docking groove 704. The limiting plate 703 is provided inside the sliding track 701. The bottom of the limiting plate 703 is slidably docked with the top of the sliding plate 702.

[0025] The blocking effect of the limiting plate 703 prevents the sliding plate 702 from tilting up when sliding inside the sliding track 701, thereby improving the sliding stability and accuracy. At the same time, it prevents the roller 705 from passing over the top of the blocking block 804, ensuring accurate and stable limiting.

[0026] Reference Figure 6 and Figure 8 The adjusting component 8 also includes an adjusting groove 801 located at the bottom of the sliding track 701. A connecting bolt 802 is slidably connected to the inner wall of the adjusting groove 801. A washer 803 is fitted on the outer arc surface of the connecting bolt 802. The washer 803 contacts and presses against the outer side of the bottom of the sliding track 701. A blocking block 804 is threadedly connected to the connecting bolt 802. The blocking block 804 is located inside the sliding track 701. The side of the blocking block 804 contacts and blocks the roller 705. The roller 705 is symmetrically arranged at both ends of the sliding plate 702. The connecting groove 704 is a waist-shaped groove. The inner diameter of one end of the waist-shaped groove is larger than the inner diameter of the other end. An arc-shaped blocking block is provided at the top of the waist-shaped groove. The arc-shaped blocking block is located above the end with the smaller inner diameter of the waist-shaped groove.

[0027] The adjustable blocking block 804 can be adjusted according to the items stored inside the storage compartment 2. By rotating the connecting bolt 802, it can be clamped and fixed to the bottom of the sliding track 701 to prevent the blocking block 804 from moving accidentally.

[0028] Reference Figure 9 and Figure 10The storage component 9 includes a limiting base 901 fixedly connected to the bottom of the inner wall of the storage compartment 2. The limiting base 901 has several equally spaced and linearly distributed limiting protrusions 903 on its top. The limiting base 901 has symmetrical sliding grooves 902 on both sides. A sliding rod 906 is slidably connected to the inner wall of the sliding groove 902. The width of the inner wall of the sliding groove 902 is greater than the outer diameter of the sliding rod 906. A sliding bracket 904 is fixedly connected to the end of the sliding rod 906 away from the sliding groove 902. A first limiting ring 905 is fixedly connected to the center of the top of the sliding bracket 904. The sliding bracket 904 is in the shape of an inverted U. A docking protrusion 907 is provided on the sliding bracket 904 directly below the first limiting ring 905. The docking protrusion 907 contacts the limiting protrusion 903.

[0029] The combination of the sliding bracket 904 and the limiting base 901 can fix the items stored inside the drawer, thereby preventing the items from tipping over when the drawer is pulled out.

[0030] In summary, when the experimental table anti-detachment drawer disclosed in this application is used, the staff holds the handle 5 and pulls it outward. At this time, the limiting ring 603 contacts the blocking spring 605 under the action of the storage compartment 2, and the blocking spring 605 produces a blocking effect on the storage compartment 2 being pulled out.

[0031] As the staff continues to pull out the storage compartment 2, the blocking spring 605 deforms under the pressure of the limiting ring 603, allowing the limiting ring 603 to pass through, thus allowing the storage compartment 2 to be pulled out. The structure of the blocking spring 605 can generate resistance to the process of pulling the storage compartment 2 out, preventing the storage compartment 2 from accidentally sliding out.

[0032] The retaining spring 605, which is fixed by connecting bolts 606, can be easily replaced and installed after metal fatigue occurs, thus reducing the maintenance difficulty of this structure.

[0033] During the process of pulling out the storage compartment 2, the roller 705 rolls inside the sliding track 701, and the roller 705 contacts and supports the inner wall of the sliding track 701, thereby suspending and supporting the storage compartment 2.

[0034] When the roller 705 slides to contact the blocking block 804, the roller 705 is blocked, and the storage drawer 2 cannot be pulled out further, thus achieving the effect of preventing the drawer from coming off.

[0035] When it is necessary to remove the storage compartment 2, first use the I-shaped connecting rod to connect with the docking groove 704, so that the limiting plate 703 can be pulled out from the sliding track 701 through the connecting rod. At this time, the sliding plate 702 can move upward within the sliding track 701. By lifting the storage compartment 2 upward, the roller 705 can pass over the top of the blocking block 804, and then the storage compartment 2 can be completely pulled out from the housing 1.

[0036] After the storage compartment 2 is pulled out, the blocking block 804 and the sliding rail 701 can be loosened by rotating the connecting bolt 802. At this time, the blocking block 804 can slide within the adjustment groove 801. When the blocking block 804 slides to a new limit position, the blocking block 804 and the washer 803 can clamp the bottom of the sliding rail 701 by rotating the connecting bolt in the opposite direction, thereby achieving the fixing effect of the blocking block 804 and forming a new maximum limit for pulling out the storage compartment 2. When the storage compartment 2 is installed back into the housing 1, the storage compartment 2 is first pushed up and pushed into the housing 1, and then the limit plate 703 is installed and inserted into the installation groove 706.

[0037] During the process of pulling out the storage compartment 2, the process of pulling out the storage compartment 2 requires overcoming the resistance of the blocking spring 605, which makes the process of pulling out the storage compartment 2 relatively fast. This makes the items stored inside the storage compartment 2 prone to tipping over. At this time, placing the items inside the first limiting ring 905 can limit the stored items. When storing, the weight of the items causes the sliding bracket 904 to press down, which in turn causes the docking protrusion 907 to contact the limiting protrusion 903. This prevents the sliding bracket 904 from sliding relative to the limiting base 901, thereby achieving a fixing effect.

[0038] When the position of the sliding bracket 904 needs to be adjusted, the sliding bracket 904 is pulled up. At this time, the sliding rod 906 slides upward relative to the sliding groove 902, so that the docking protrusion 907 does not contact the limiting protrusion 903. At this time, the sliding bracket 904 can slide relative to the limiting base 901, thereby achieving the effect of adjusting the position of the sliding bracket 904, so as to achieve the effect of classifying and storing different items.
