Description

Technical Field

[0001] This utility model relates to the field of cabinet drawer technology, specifically to a slanted-opening drawer that prevents the door panel from sagging during slanted opening. Background Technology

[0002] In kitchen storage, commonly used cooking utensils are usually placed on the stovetop or stored in drawers inside cabinets. The former takes up stovetop space, making the stovetop surface look messy; the latter makes it inconvenient to access and store cooking utensils. Therefore, slanted-opening cabinet drawers with tilting doors have appeared on the market.

[0003] Existing angled drawer doors typically have a structure where the lower edge of the drawer door is hinged to the front edge of the drawer bottom via a hinge mechanism (e.g., a hinge). The side panels of the drawer and the vertical edges of the drawer door are each hinged via a diagonal extension mechanism. In this type of drawer, the lower edge of the drawer door tends to sag during tilting and opening, causing it to overlap and collide with the cabinet frame below. This results in an unsmooth opening and closing process, generates collision noise, and in severe cases, prevents the drawer from opening to its maximum tilt angle, significantly impacting the user experience. This invention proposes an angled drawer that prevents the door from sagging during tilting, aiming to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a slanted drawer that prevents the door panel from sagging during slanted opening. The upper end of the side panel is connected to the upper end of the corresponding side of the door panel through a slanted opening door pull rod mechanism, and the lower end of the side panel is connected to the lower end of the corresponding side of the door panel through a four-bar linkage mechanism with a lifting function. During the process of the door panel tilting and flipping open, the four-bar linkage mechanism causes the door panel to undergo a composite combination of rotation, lifting, and translation movements in a coordinated and synchronous manner. This results in an overall lifting effect on the door panel. Therefore, when the slanted drawer of this invention is installed inside a cabinet, the lower edge of the door panel will not collide with the cabinet frame below the drawer during the process of tilting and flipping open, effectively eliminating collision noise. At the same time, it ensures that the door panel can smoothly tilt and flip open to the maximum opening angle, significantly improving the user experience.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a slanted-opening drawer that prevents the door panel from sinking during slanted opening. The drawer includes a base plate, two side plates, and a door panel. The two side plates are correspondingly arranged on the left and right sides of the base plate. The upper ends of the side plates are connected to the upper ends of the corresponding side of the door panel via a slanted-opening door pull rod mechanism capable of reciprocating along the front-rear direction. The lower ends of the side plates are connected to the lower ends of the corresponding side of the door panel via a four-bar linkage mechanism. During the process of the door panel tilting and flipping open relative to the front ends of the two side plates, the four-bar linkage mechanism lifts the door panel upwards.

[0006] This utility model discloses a slanted-opening drawer that prevents the door panel from sagging during slanted opening. The upper end of the side panel is connected to the upper end of the corresponding side of the door panel via a slanted-opening door pull rod mechanism, and the lower end of the side panel is connected to the lower end of the corresponding side of the door panel via a four-bar linkage mechanism with a lifting function. During the process of the door panel tilting and flipping open, the four-bar linkage mechanism causes the door panel to undergo a composite movement consisting of rotation, lifting, and translation in a coordinated and synchronous manner. This results in an overall lifting effect on the door panel. Therefore, when this utility model's slanted-opening drawer is installed inside a cabinet, the lower edge of the door panel will not collide with the cabinet frame below the drawer during the process of tilting and flipping open, effectively eliminating collision noise. At the same time, it ensures that the door panel can smoothly tilt and flip open to the maximum limit opening angle, significantly improving the user experience.

[0007] A preferred technical solution is that the angled door lever mechanism includes a base plate two detachably fixedly installed on the upper end of the side plate. The base plate two is provided with a lever mechanism capable of reciprocating and extending along the horizontal front-back direction. The front end of the lever mechanism is hinged to a lever one for hinged connection with the door panel, and the rear end of the lever mechanism is equipped with an elastic tension member. The lever mechanism has two states: unlocked and locked.

[0008] When in the unlocked state, the lever mechanism can extend forward under the action of a forward pulling force, or the lever mechanism can retract and reset backward under the action of the elastic reset force of the elastic tension member;

[0009] When locked, the lever mechanism is locked at its maximum forward extension position, and works in conjunction with the four-bar linkage to lock the door panel at its maximum opening angle when tilted outward. The lever mechanism in the angled door lever mechanism has both unlocked and locked states. When the door panel is opened at an angle to retrieve or place items, the lever mechanism is locked, thus locking the door panel at its maximum opening angle. This effectively prevents the door panel from closing at a certain angle or completely closing under the elastic force of the internal elastic member when the operator is retrieving items from the drawer, ensuring convenient operation. After retrieving or placing items, the operator only needs to apply a certain pushing force to the back of the drawer to change the lever mechanism from the locked state to the unlocked state. The door panel will then gradually close under the elastic restoring force of the elastic member, further improving the user experience.

[0010] A further preferred technical solution includes a second pull rod, a connecting block, a sliding block, and a damper. The rear end of the first pull rod is hinged to the front end of the second pull rod. The rear end of the second pull rod has two downwardly extending protrusions, a first protrusion and a second protrusion, and a groove 1 located between the first and second protrusions with an upward opening. The first protrusion is located at the rear end of the second pull rod, and the length of the first protrusion is less than the length of the second protrusion. The upper side of the connecting block has a third protrusion located at the rear end and a fourth protrusion located at the front end, and a groove 2 located between the third and fourth protrusions with an upward opening. The sliding block... The structure is an L-shaped block with a horizontal arm and a vertical arm. The upper side of the horizontal arm has a protrusion five at the front end and the upper side of the horizontal arm has the vertical arm at the rear end. The protrusion five, the vertical arm, and the upper side of the horizontal arm enclose to form an upward-opening groove three. The rear end of the connecting block is hinged to the vertical arm. The protrusion four at the front end of the connecting block is movably inserted into the groove one on the pull rod two. The protrusion one at the rear end of the pull rod two is movably inserted into the groove two on the connecting block. The elastic tension member and the damper are both fixed horizontally between the sliding block and the rear end face of the base plate two.

[0011] When the lever mechanism is in the locked state, the front end of the connecting block rotates and tilts downwards, and the left end of the lower side of protrusion one and the right end of the upper side of protrusion four form a dead contact point.

[0012] When the pull rod mechanism is in the unlocked state, protrusion one and protrusion four disengage and are movably inserted into the groove two on the connecting block. The pull rod mechanism has a compact and reasonable structural design, which is easy to integrate and implement on the base plate two, and is highly practical. The damper located at the rear end of the pull rod mechanism has a buffering effect, effectively avoiding structural damage caused by violent impact due to excessive speed during the opening and closing of the door panel, and also effectively reducing noise during the opening and closing of the door panel.

[0013] A further preferred technical solution includes three interconnected cavities—Cavity 1, Cavity 2, and Cavity 3—arranged sequentially from front to back inside one side of the substrate 2. The front end of Cavity 1 extends through the front end face of the substrate 2. The lower edge of Cavity 1 is a sloping structure that gradually expands downwards from back to front. The upper front end of Cavity 2 is connected to the rear end of Cavity 1. The substrate 2 has a slot 3 located in the middle of the front end of Cavity 3 and a corresponding slot 2 located in the middle of the rear end of Cavity 3. The rear end of the substrate 2 also has two slots 1 located above and below the slots 2. The pull rod 1 is located inside Cavity 1, and its front end is hinged to… The connecting seat two is used to fix the outer door panel. The pull rod two, connecting block and sliding block are located inside the cavity two. The rear end of the sliding block has three T-shaped grooves with openings facing the rear side at longitudinal intervals. The front end of the damper cylinder is snapped and fixed inside the third groove and the rear end is snapped and fixed inside the second groove. The piston rod end of the damper is snapped and fixed inside a T-shaped groove located in the middle of the rear end of the sliding block. The elastic tension member includes two corresponding to the upper and lower sides of the damper. The front end of the elastic tension member is snapped and fixed inside a corresponding T-shaped groove and the rear end is snapped and fixed inside a corresponding first groove. The pull rod mechanism is embedded and integrated into the cavity on the base plate two, so that the overall stability of the angled door pull rod mechanism is good, thereby ensuring that the pull rod mechanism has good stability when reciprocating in the horizontal direction. The two elastic tension members corresponding to the upper and lower sides of the damper further ensure that the pull rod mechanism has good stability when reciprocating in the horizontal direction.

[0014] A further preferred technical solution includes a pin extending vertically to the left and right sides at both ends of the connecting block. The side of the vertical arm facing the side plate has a stepped groove adjacent to the groove three. A pin hole is provided on the vertical bottom wall of the stepped groove. The rear end of the connecting block is fitted into the stepped groove, and the end of the pin at the rear end of the connecting block facing away from the side plate is movably connected to the pin hole. The rear end of the connecting block is fitted into the stepped groove on the sliding block, and a hinge point is formed by the pin at the rear end connecting to the pin hole on the bottom wall of the stepped groove. This simple installation method ensures good stability when the connecting block rotates, allowing the angled door lever mechanism to smoothly transition to the locked state when the door panel is opened to its maximum angle, and similarly, to smoothly transition to the unlocked state when the door panel is closed.

[0015] A further preferred technical solution includes cover plates corresponding to the opening sides of cavities two and three. Guide grooves are correspondingly formed on the vertical bottom wall of cavity two and on the cover plates. The guide grooves include a horizontal straight groove and an arc-shaped groove that gradually bends forward and downward from the front end of the straight groove. One end of a pin located at both ends of the connecting block is movably inserted into the guide groove on the base plate two, and the other end of the pin located at both ends of the connecting block is movably inserted into the guide groove on the cover plate. The cover plates limit and restrain the pull rod mechanism embedded in the cavity on the base plate two, effectively preventing the pull rod mechanism from detaching from the cavity on the base plate two. The two ends of the pins on the connecting block are movably inserted into the guide grooves on the base plate two or the cover plate, further improving the stability of the pull rod mechanism during the opening and closing of the door panel.

[0016] A further preferred technical solution includes several mounting holes 2 on both the outer periphery and the interior of the substrate 2; an ear plate on the outer periphery of the cover plate, with mounting holes 3 on the ear plate; the cover plate being fixedly connected to the substrate 2 by screws passing through the corresponding mounting holes 2 and 3; and the substrate 2 being fixedly mounted to one side of the side panel by screws passing through the mounting holes 2 on the outer periphery. The method of fixing the cover plate to the substrate 2 is simple, and the method of fixing the substrate 2 to the drawer side panel is also simple, resulting in high feasibility of application.

[0017] A further preferred technical solution is that the second base plate is fixedly installed on the upper end of the side panel facing the inside of the drawer, and a decorative panel is fixedly installed on the side of the second base plate facing the inside of the drawer. The elastic tension member is a spring. The angled door pull rod mechanism is detachably installed on the upper end of the side panel facing the inside of the drawer. The installation method is simple, and the decorative panel serves to conceal and decorate the angled door pull rod mechanism, ensuring the overall aesthetics of the drawer interior. At the same time, the decorative panel provides protection and dust protection for the pull rod mechanism inside the angled door pull rod mechanism, ensuring the normal and durable use of the angled door pull rod mechanism and preventing accidents caused by clamping foreign objects, thus improving safety. The spring is commercially available and economical.

[0018] A preferred technical solution further includes a four-bar linkage comprising a base plate, a rod, a second rod, and a connecting seat. The base plate is fixedly installed on the lower end of the side panel, and the connecting seat is fixedly installed on the lower end of the corresponding side of the door panel. One end of the first rod is hinged to the upper end of the base plate to form hinge point one, and the other end is hinged to the upper end of the connecting seat to form hinge point four. One end of the second rod is hinged to the lower end of the base plate to form hinge point two, and the other end is hinged to the lower end of the connecting seat to form hinge point three. When the door panel is in a closed state: hinge point one is located above the line connecting hinge points two and four, and hinge point three is located below the line connecting hinge points two and four. When the door panel is in the maximum opening angle position of tilting outwards: both hinge points one and hinge point three are located above the line connecting hinge points two and four. The four-bar linkage mechanism is ingeniously and rationally designed. When the door panel is closed, hinge points one and three are located on the lower and upper sides of the line connecting hinge points two and four, respectively. This ensures that the four-bar linkage is in a stable initial quadrilateral frame state, guaranteeing good fit between the door panel and the front edge of the side panel. When the door panel is at its maximum opening angle, tilted outwards, hinge point three crosses the line connecting hinge points two and four and is located above this line, causing the four-bar linkage to transition into a stable dead-point locking state. This design creates a stable locking state between the lower edge of the door panel at its maximum opening angle and the lower edge of the side panel. This effectively prevents the door panel from closing at a certain angle or completely closing under the pulling force of the angled door lever mechanism when the operator is taking items out of the drawer. This ensures convenient operation when taking out or placing items. After taking out or placing items, the operator only needs to apply a certain pushing force to the back of the drawer to change the four-bar linkage mechanism from the locked state to the unlocked state, and the door panel can then close and reset normally, further improving the user experience.

[0019] A further preferred technical solution includes a mounting hole on the substrate, which is fixedly mounted to the lower end of the corresponding side panel facing the inside of the drawer via screws passing through the mounting hole. A decorative panel is fixedly mounted on the side of the substrate facing the inside of the drawer. The four-bar linkage is detachably mounted on the lower end of the side panel facing the inside of the drawer, simplifying installation. The decorative panel and the four-bar linkage serve to conceal and decorate, ensuring the overall aesthetics of the drawer interior. Simultaneously, the decorative panel and the four-bar linkage provide protection and dust prevention, ensuring the longevity of the four-bar linkage and preventing accidents involving foreign objects, thus improving safety.

[0020] The advantages and beneficial effects of this utility model are as follows:

[0021] 1. This utility model discloses a slanted-opening drawer that prevents the door panel from sagging during slanted opening. The upper end of the side panel is connected to the upper end of the corresponding side of the door panel via a slanted-opening door pull rod mechanism, and the lower end of the side panel is connected to the lower end of the corresponding side of the door panel via a four-bar linkage mechanism with a lifting function. During the process of the door panel tilting and flipping open, the four-bar linkage mechanism causes the door panel to undergo a composite combination of rotation, lifting, and translation movements in a coordinated and synchronous manner. This results in an overall lifting effect on the door panel. Therefore, when this utility model's slanted-opening drawer is installed inside a cabinet, the lower edge of the door panel will not collide with the cabinet frame below the drawer during the process of tilting and flipping open, effectively eliminating collision noise. At the same time, it ensures that the door panel can smoothly tilt and flip open to the maximum limit opening angle, significantly improving the user experience.

[0022] 2. The lever mechanism of the angled door has two states: unlocked and locked. When the door is angled open to retrieve or place items, the lever mechanism is in the locked state, thus locking the door at its maximum opening angle. This effectively prevents the door from closing at a certain angle or completely closing under the elastic force of the internal elastic components when the operator is retrieving items from the drawer, ensuring convenient operation. After retrieving or placing items, the operator only needs to apply a certain push to the back of the drawer to change the lever mechanism from the locked state to the unlocked state. The door will then gradually close under the elastic restoring force of the elastic components, further improving the user experience.

[0023] 3. The pull rod mechanism has a compact and reasonable structural design, which is easy to integrate and implement on the second base plate and has strong practicality. The damper located at the rear end of the pull rod mechanism has a buffering effect, which effectively avoids structural damage caused by excessive speed and violent impact during the opening and closing of the door panel, and at the same time effectively reduces the noise during the opening and closing of the door panel.

[0024] 4. The pull rod mechanism is embedded and integrated inside the cavity on the second base plate, which makes the overall stability of the diagonal door pull rod mechanism good, thus ensuring that the pull rod mechanism has good stability when reciprocating in the horizontal direction; corresponding to the two elastic tension members located on the upper and lower sides of the damper, the stability of the pull rod mechanism is further ensured when reciprocating in the horizontal direction.

[0025] 5. The rear end of the connecting block is embedded in the stepped groove on the sliding block. A hinge point is formed by the pin shaft located at the rear end passing through the pin hole on the bottom wall of the stepped groove. The installation method is simple and ensures good stability when the connecting block rotates. When the door panel is opened to the maximum angle, the angled door pull rod mechanism can smoothly change to the locked state. Similarly, when the door panel is closed, the angled door pull rod mechanism can smoothly change to the unlocked state.

[0026] 6. The cover plate limits and restrains the pull rod mechanism embedded in the cavity of the second base plate, effectively preventing the pull rod mechanism from coming out of the cavity of the second base plate; the two ends of the pin on the connecting block are movably inserted into the guide groove on the second base plate or the cover plate, which further improves the stability of the pull rod mechanism during the opening and closing of the door.

[0027] 7. The second base plate is fixedly installed on the upper end of the side panel facing the inside of the drawer. A decorative panel is fixedly installed on the side of the second base plate facing the inside of the drawer. The elastic tensioning element is a spring. The angled door pull rod mechanism is detachably installed on the upper end of the side panel facing the inside of the drawer. The installation method is simple, and the decorative panel serves to conceal and decorate the angled door pull rod mechanism, ensuring the overall aesthetics of the drawer interior. At the same time, the decorative panel provides protection and dust protection for the pull rod mechanism inside the angled door pull rod mechanism, ensuring the normal and durable use of the angled door pull rod mechanism and preventing accidents caused by clamping foreign objects, thus improving safety. The spring is readily available and economical.

[0028] 8. The four-bar linkage structure is ingeniously and rationally designed. When the door panel is closed, hinge points one and three are located on the lower and upper sides of the line connecting hinge points two and four, respectively, ensuring that the four-bar linkage is in a stable quadrilateral frame initial state and that the door panel fits well with the front edge of the side panel. When the door panel is in its maximum opening angle, tilted outwards, hinge point three crosses the line connecting hinge points two and four and is located above the line connecting hinge points two and four, causing the four-bar linkage to transform into a stable dead-point locking state. This design ensures that the lower edge of the door panel, which is at its maximum opening angle, and the lower edge of the side panel form a stable locking state. This effectively prevents the door panel from closing at a certain angle or completely closing under the pulling force of the angled door lever mechanism when the operator is taking items out of the drawer. This ensures convenient operation when taking out or placing items. After taking out or placing items, the operator only needs to apply a certain pushing force to the back of the drawer to change the four-bar linkage mechanism from the locked state to the unlocked state, and the door panel can then close and reset normally, further improving the user experience.

[0029] 9. The four-bar linkage is detachably installed on the lower end of the side panel facing the inside of the drawer. The installation method is simple, and the decorative panel and the four-bar linkage serve to conceal and decorate, ensuring the overall aesthetics of the drawer interior. At the same time, the decorative panel and the four-bar linkage provide protection and dust prevention, ensuring the four-bar linkage has good durability and preventing accidents caused by foreign objects being caught, thus improving safety.

Detailed Implementation

[0054] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0055] Example

[0056] like Figures 1-23 As shown, a drawer with a tilting door that prevents the door panel from sinking during tilting opening includes a base plate 1, two side plates 2, and a door panel 3. The two side plates 2 are respectively arranged on the left and right sides of the base plate 1. The upper end of the side plate 2 is connected to the upper end of the corresponding side of the door panel 3 through a tilting door pull rod mechanism 5 that can reciprocate and extend in the front-back direction. The lower end of the side plate 2 is connected to the lower end of the corresponding side of the door panel 3 through a four-bar linkage 4. When the front end of the door panel 3 tilts outward and opens relative to the two side plates 2, the four-bar linkage 4 lifts the door panel 3 upward.

[0057] Preferably, the angled door lever mechanism 5 includes a base plate 2 5-1 detachably fixedly installed on the upper end of the side plate 2. The base plate 2 5-1 is provided with a lever mechanism 5-2 capable of reciprocating along the horizontal front-back direction. The front end of the lever mechanism 5-2 is hinged to a lever 5-2b for hinged connection with the door plate 3. The rear end of the lever mechanism 5-2 is equipped with an elastic tension member 5-2f. The lever mechanism 5-2 has two states: unlocked and locked.

[0058] When in the unlocked state, the lever mechanism 5-2 can extend forward under the action of a forward pulling force, or the lever mechanism 5-2 can retract and reset backward under the action of the elastic reset force of the elastic tension member 5-2f.

[0059] When in the locked state, the lever mechanism 5-2 is locked at the limit position of forward extension, and works in conjunction with the four-bar linkage 4 to lock the door panel 3 at the maximum limit opening angle position of tilting outwards.

[0060] More preferably, the pull rod mechanism 5-2 further includes a second pull rod 5-2c, a connecting block 5-2d, a sliding block 5-2e, and a damper 5-2g. The rear end of the first pull rod 5-2b is hinged to the front end of the second pull rod 5-2c. The rear end of the second pull rod 5-2c has downwardly extending protrusions 5-2c-1 and 5-2c-2, and a downwardly opening groove 5-2c located between the protrusions 5-2c-1 and 5-2c-2. -3, Protrusion 1 5-2c-1 is located at the rear end of pull rod 2 5-2c, and the length of protrusion 1 5-2c-1 is less than the length of protrusion 2 5-2c-2. The upper side of the connecting block 5-2d has protrusion 3 5-2d-1 located at the rear end and protrusion 4 5-2d-2 located at the front end, as well as groove 2 5-2d-3 located between protrusion 3 5-2d-1 and protrusion 4 5-2d-2 with an upward opening. The sliding block 5-2e is an L-shaped block. The structure comprises a horizontal arm 5-2e-1 and a vertical arm 5-2e-2. The upper side of the horizontal arm 5-2e-1 has a protrusion 5-2e-3 at its front end, and the upper side of the horizontal arm 5-2e-1 has the vertical arm 5-2e-2 at its rear end. The protrusion 5-2e-3, the vertical arm 5-2e-2, and the upper side of the horizontal arm 5-2e-1 together form an upward-opening groove 5-2e-4.

[0070] More preferably, the connecting seat 4-5 and the connecting seat 5-2a are independent structural components, or it may also include a connecting plate 6 fixedly installed on the side end of the door panel 3 facing the inside of the drawer, wherein the lower end of the connecting plate 6 is bent to form the connecting seat 4-5 and the upper end is bent to form the connecting seat 5-2a.

[0071] The base plate 4-1 has a limiting plate 4-1a extending into the drawer in the middle. The front edge of the rod 4-2 has a limiting plate 4-2a corresponding to the limiting plate 4-1a. The lower edge of the connecting plate 6 is bent to have a limiting plate 6-1 extending horizontally into the drawer. When the door panel 3 is in the closed state, the limiting plate 4-2a abuts against the front side of the limiting plate 4-1a, and the lower end face of the limiting plate 6-1 abuts against the upper end face of the bottom plate 1. Connector 1 and Connector 2 can be independent structural components or integral molded components integrated into the connecting plate.

[0074] Furthermore, the substrate 2 5-1 has a notch K on the upper rear side, and the front wall of the notch K is a slope L that gradually extends downwards from front to back. The notch K on the upper rear side of the substrate 2 5-1 facilitates the installation of a built-in pull-out basket on the rear side above the drawer, and the front end of the bottom of the pull-out basket can be set as a slope structure adapted to the slope L. The slope L and the slope structure at the front end of the pull-out basket can be magnetically connected together by a magnetic connector to meet the needs of multi-category storage of items, and also to meet the need to push the pull-out basket back to expose the upper port of the drawer for easy access to items.

[0075] Furthermore, preferably, a storage box is installed on the side of the door panel 3 facing the inside of the drawer to meet the need for multiple categories of storage of items.

[0076] The present invention relates to the working principle of a slanted drawer that prevents the door panel from sagging during slanted opening:

[0077] The hinge point between connector 2 5-2a and the front end of pull rod 1 5-2b is designated as hinge point five E1; the hinge point between the rear end of pull rod 1 5-2b and the front end of pull rod 2 5-2c is designated as hinge point six E2; and the position where one end of the rear pin 5-2d-4 of connector block 5-2d movably passes through the pin hole J is designated as hinge point seven E3 (see appendix). Figure 12 ).

[0078] Step 1: The initial state is marked by the door panel 3 being perpendicularly attached to the front edge of the drawer side panel 2. At this time, the four-bar linkage 4 is in the initial state of the quadrilateral frame, with hinge point A and hinge point C located on the upper and lower sides of the line connecting hinge point B and hinge point D, respectively (see Appendix). Figure 13 When it is necessary to retrieve or place items, the operator holds the door panel 3 and applies a certain pulling force forward, causing the door panel 3 to gradually tilt and flip outward to its maximum opening angle. During this process, the door panel 3 flips forward and downward with hinge point five E1 as the fulcrum, the rear end of pull rod one 5-2b flips forward and downward with hinge point six E2 as the fulcrum, and pull rod two 5-2c moves forward to its limit position. At this time, the front end of connecting block 5-2d rotates forward and downward with hinge point seven E3 as the fulcrum, so that the lower left end of protrusion one 5-2c-1 and the upper right end of protrusion four 5-2d-2 form a dead contact point G1 (see appendix). Figure 15 and 16 At this point, the lever mechanism 5-2 is in the locked state, and the four-bar linkage 4 moves synchronously with the angled door lever mechanism 5. Hinge point 3C eventually crosses the line connecting hinge point 2B and hinge point 4D and is located above the line connecting hinge point 2B and hinge point 4D. At this point, the four-bar linkage 4 transforms into a stable dead-point mechanism locked state (see Appendix). Figure 17 and 18 That is, the four-bar linkage 4 and the inclined door lever mechanism 5 work together to lock the door panel 3 at the maximum limit opening angle when tilted outward. During this process, the door panel 3 undergoes a combined combination of rotation, lifting, and translation, causing the door panel 3 to be lifted upward by a certain distance (during this process, even if the door panel 3 sinks a certain distance during the tilted outward opening, the distance that the four-bar linkage 4 lifts the door panel 3 will offset the distance that the door panel 3 sinks, so that the door panel 3 appears to be lifted upward).

[0079] Step 2: After placing or removing items from the drawer, the operator holds the door panel 3 and applies a certain pushing force F to the rear, so that the lower left end of the protrusion 1 5-2c-1 separates from the upper right end of the protrusion 4 5-2d-2 and abuts against the protrusion 3 5-2d-1 to form abutment point G2 (see appendix). Figure 21At this point, the lever mechanism 5-2 changes from the locked state to the unlocked state, and hinge point 3C on the four-bar linkage 4 crosses the line connecting hinge point 2B and hinge point 4D and is located below the line connecting hinge point 2B and hinge point 4D. At this time, the four-bar linkage 4 also changes to the unlocked state (see appendix). Figure 22 and 23 The operator can continue to apply a backward pushing force to close the door panel 3, or release the door panel 3. Under the elastic restoring force of the elastic tension member 5-2f, the door panel 3 will continue to move backward and be sucked back until it abuts against the front edge of the drawer side panel 2 again.

[0080] In the aforementioned slanted-opening drawer, one or both of the above-mentioned four-bar linkage 4 and slanted-opening door pull rod mechanism 5 with locking and unlocking functions can be selectively installed on the side panel 2. As long as the door panel 3 can play a locking and positioning function when tilted outward to the maximum limit opening angle position, it is within the protection scope of this utility model.

[0081] This utility model discloses a slanted-opening drawer that prevents the door panel from sagging during slanted opening. The upper end of the side panel is hinged to the upper end of the corresponding side of the door panel via a slanted-opening pull rod mechanism, and the lower end of the side panel is hinged to the lower end of the corresponding side of the door panel via a four-bar linkage mechanism. This allows the door panel to have a complex combination of rotation, lifting, and translational movements during the tilting and outward flipping opening and closing process. As a result, the movement trajectory of the lower edge of the door panel always remains above the horizontal plane where the lower edge of the door panel is when the door panel is closed. Therefore, when this utility model's slanted-opening drawer is installed inside a cabinet, the lower edge of the door panel will not collide with the cabinet frame body below the drawer when the door panel moves between the tilting and outward flipping opening and closing positions, effectively eliminating collision noise. At the same time, it ensures that the door panel can smoothly tilt and flip outward to the maximum opening angle position, significantly improving the user experience.

[0082] This utility model discloses a slanted-opening drawer that prevents the door panel from sagging during slanted opening. The slanted-opening door pull rod mechanism and the four-bar linkage mechanism installed on the side panel have good synergy and compatibility. When the door panel is in the closed state, the elastic pull member at the rear end of the slanted-opening door pull rod mechanism applies a rearward pulling force, which makes the door panel tightly fit against the front edge surface of the side panel. Compared with existing slanted-opening drawers, this further improves the sealing performance inside the drawer.

[0083] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
