Technical Field
[0001] This utility model relates to the field of cabinet drawer technology, specifically to a slanted door mechanism for cabinet drawers and a slanted door cabinet drawer using the same mechanism. Background Technology
[0002] With the continuous improvement of living standards, people's pursuit of material life is also constantly increasing. Cabinets have become the most common and essential storage component in home organization. In kitchen organization, commonly used cooking utensils are generally placed on the stove or stored in cabinets. The former takes up stove space and makes the stove look cluttered; the latter is inconvenient to access. Therefore, slanted drawers with tilting and outward opening functions have appeared on the market. Although existing slanted drawers can open at an angle, they lack a locking function when tilted, causing the drawer door to not maintain a stable maximum angle when tilted outward. Under the pulling force of the internal slanted pull mechanism, the drawer door will automatically close at a certain angle or even completely. Therefore, the operator needs to hold the drawer door with one hand at all times while using the other hand to take items out of the drawer, resulting in poor overall operability and a poor user experience. To address this, this utility model proposes a slanted door mechanism for cabinet drawers and a slanted door cabinet drawer using the same mechanism, aiming to solve the above-mentioned technical problems. Summary of the Invention
[0003] The purpose of this utility model is to overcome the defects existing in the prior art and provide a slanted door mechanism for cabinet drawers and a slanted door cabinet drawer using the same. The slanted door mechanism of this utility model has two states: unlocked and locked. When the drawer door is slanted open to retrieve or place items, the pull rod mechanism is in the locked state, thus locking the drawer door at its maximum opening angle. This effectively prevents the drawer door 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 rear of the drawer to change the pull rod mechanism from the locked state to the unlocked state. The drawer door will then gradually close under the elastic restoring force of the elastic member, significantly improving the user experience.
[0004] One objective of this utility model is to design a slanted opening mechanism for a cabinet drawer, comprising a base plate, on which a pull rod mechanism capable of reciprocating along a horizontal direction is provided. The front end of the pull rod mechanism is hinged to a pull rod for hinged connection with an external drawer door panel, and the rear end of the pull rod mechanism is equipped with an elastic tension member. The pull rod mechanism has two states: unlocked and locked.
[0005] When in the unlocked state, the lever mechanism can slide forward under the action of a forward pulling force, or the lever mechanism can slide backward under the action of the elastic restoring force of the elastic tension member;
[0006] When locked, the lever mechanism is locked at the limit position of forward sliding, and the drawer door is at the maximum limit opening angle of tilting outward.
[0007] This utility model discloses a slanted opening mechanism for a cabinet drawer, wherein the pull rod mechanism has two states: unlocked and locked. When the drawer door is slanted open to retrieve or place items, the pull rod mechanism is in the locked state, thereby locking the drawer door at its maximum opening angle. This effectively prevents the drawer door from closing at a certain angle or completely closing under the elastic force of the internal elastic member when the operator is retrieving or placing items inside the drawer, ensuring convenient operation when retrieving or placing items. After retrieving or placing items, the operator only needs to apply a certain pushing force to the rear of the drawer door to change the pull rod mechanism from the locked state to the unlocked state. The drawer door will then gradually close and return to its original position under the elastic return force of the elastic member, significantly improving the user experience.
[0008] A preferred technical solution is that the pull rod mechanism further 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 is L. The block structure has 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.
[0009] 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.
[0010] 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, and its layout and integration on the base plate are highly feasible and practical. The damper located at the rear end of the pull rod mechanism has a buffering effect, effectively reducing structural damage and noise generated during the opening and closing of the drawer door, further improving the user experience.
[0011] A further preferred technical solution is that the oblique opening mechanism for the cabinet drawer includes two sets of symmetrical structures, and in use, the two sets of oblique opening mechanisms for the cabinet drawer are installed on the inner sides of the two side panels of the drawer respectively.
[0012] The substrate contains, from front to back, three horizontally arranged cavities, cavity one, cavity two, and cavity three, with openings facing the respective side plates. Cavity one's front end extends through the front face of the substrate, and its lower edge is a sloping structure that gradually expands downwards from back to front. The upper front side of cavity two is connected to the rear end of cavity one. The substrate has a slot three located at the middle of the front end of cavity three and a corresponding slot two located at the middle of the rear end of cavity three. The rear end of the substrate also has two slots one corresponding to the upper and lower sides of slot two. A pull rod one is located inside cavity one, and its front end is hinged to an external mounting bracket. The drawer door panel connecting seat, the pull rod two, the connecting block and the 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 locked and fixed inside the third groove, and the rear end is locked and fixed inside the second groove. The end of the damper piston rod is locked 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 locked and fixed inside a corresponding T-shaped groove, and the rear end is locked and fixed inside a corresponding first groove. The pull rod mechanism is embedded and integrated into the cavity on the base plate, making the overall stability of the angled door mechanism of this utility model consistent and good, thus 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 the stability of the pull rod mechanism when reciprocating in the horizontal direction.
[0013] 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 body 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 simplifies the installation and ensures good stability when the connecting block rotates.
[0014] 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, 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, effectively preventing the pull rod mechanism from detaching from the cavity on the base plate. The two ends of the pins on the connecting block are movably inserted into the guide grooves on the base plate or cover plate, thereby further improving the stability of the pull rod mechanism during the opening and closing of the drawer door.
[0015] A further preferred technical solution includes several mounting holes 1 on both the outer periphery and the interior of the substrate; an ear plate on the outer periphery of the cover plate, with mounting holes 2 on the ear plate; the cover plate being fixedly connected to the substrate by screws passing through the corresponding mounting holes 1 and 2; and the substrate being fixedly mounted to the drawer side panel by screws passing through the mounting holes 1 on the outer periphery. The method of fixing the cover plate to the substrate is simple, and the method of fixing the substrate to the drawer side panel is also simple, resulting in high feasibility for application.
[0016] A further preferred technical solution is that a decorative panel is embedded and fixed on one side of the base plate facing the inside of the drawer, and the elastic tension member is a spring. The decorative panel serves to decorate the outer side of the base plate, improving the visual aesthetics; the elastic tension member is a spring, which is commercially available, ensuring the smooth fabrication and implementation of the slanted door mechanism of this utility model.
[0017] A further preferred technical solution includes a notch on the upper rear side of the substrate, with the front wall of the notch being a slope that gradually extends downwards from front to back. A magnet is installed inside the substrate, abutting against the slope. The notch on the upper rear side of the substrate facilitates the installation of a built-in pull-out basket above the drawer using the angled door mechanism of this invention. The pull-out basket is magnetically attracted and fixed together with the magnet on the angled door mechanism, achieving the effect of simultaneously pulling out the drawer and the pull-out basket for easy access to items.
[0018] The second objective of this utility model is to design a slanted-opening cabinet drawer, including a drawer, a drawer door panel, and a bottom panel. A slanted-opening door pull rod mechanism is installed on the left and / or right side panels of the drawer. The slanted-opening door pull rod mechanism is the aforementioned slanted-opening door mechanism for cabinet drawers. The lower end of the drawer door panel is hinged to the front end of the bottom panel via a hinge. The left and / or right edges of the drawer door panel are hinged to the left end of the corresponding slanted-opening door pull rod mechanism.
[0019] This utility model discloses a slanted-opening cabinet drawer. When the drawer door is slanted to its maximum opening angle, the pull rod mechanism is locked. This effectively prevents the drawer door from closing at a certain angle or completely closing under the elastic pull of the internal elastic member when the operator is taking items out of the drawer. This ensures the convenience of taking out and putting in items and significantly improves the user experience.
[0020] A preferred technical solution also includes a pull-out basket slidably mounted on the rear side above the drawer. The pull-out basket is located at the notch slots of the left and right diagonal door handle mechanisms. The front side of the pull-out basket has a front inclined plate that corresponds to and fits against the inclined surfaces of the left and right diagonal door handle mechanisms. Each end of the front inclined plate is equipped with a second magnet corresponding to a first magnet on the left and right diagonal door handle mechanisms. The pull-out basket is magnetically attracted and fixed to the inclined surfaces of the left and right diagonal door handle mechanisms by the second magnet. A storage box is installed on the inner side of the drawer door panel. The pull-out basket is magnetically attracted and fixed to the inclined surfaces of the left and right diagonal door handle mechanisms by the second magnet, so that the pull-out basket can be pulled out along with the drawer when it is pulled out, achieving a hidden linkage effect between the pull-out basket and the drawer, ensuring convenient dual operation for retrieving and placing items into and out of both the drawer and the pull-out basket.
[0021] The advantages and beneficial effects of this utility model are as follows:
[0022] 1. This utility model discloses a slanted opening mechanism for a cabinet drawer, wherein the pull rod mechanism has two states: unlocked and locked. When the drawer door is slanted open to retrieve or place items, the pull rod mechanism is in the locked state, thereby locking the drawer door at its maximum opening angle. This effectively prevents the drawer door from closing at a certain angle or completely closing under the elastic force of the internal elastic member when the operator retrieves or places items inside the drawer, ensuring convenient operation when retrieving or placing items. After retrieving or placing items, the operator only needs to apply a certain pushing force to the rear of the drawer to change the pull rod mechanism from the locked state to the unlocked state. The drawer door will then gradually close and return to its original position under the elastic return force of the elastic member, significantly improving the user experience.
[0023] 2. The pull rod mechanism has a compact and reasonable structural design. Its layout and integration on the base plate are highly feasible and practical. The damper located at the rear end of the pull rod mechanism has a buffering effect, which effectively reduces structural damage and noise generated during the opening and closing of the drawer door, further improving the user experience.
[0024] 3. The tie rod mechanism is embedded and integrated into the cavity on the base plate, which makes the overall stability of the inclined door mechanism of this utility model consistent and good, thereby ensuring that the tie 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 tie rod mechanism when reciprocating in the horizontal direction is further ensured.
[0025] 4. The cover plate limits and restrains the pull rod mechanism embedded in the cavity of the base plate, effectively preventing the pull rod mechanism from coming out of the cavity of the base plate; the two ends of the pin on the connecting block are movably inserted into the guide groove on the base plate or the cover plate, thereby further improving the stability of the pull rod mechanism during the opening and closing of the drawer door.
[0026] 5. The upper rear side of the base plate has a notch, which facilitates the installation of a built-in pull-out basket above the drawer using the slanted door mechanism of this utility model. The pull-out basket is magnetically attracted and fixed together with the magnet on the slanted door mechanism, so as to achieve the effect of pulling out the drawer and the pull-out basket at the same time to facilitate the retrieval and placement of items.
[0027] 6. The present invention relates to a slanted-opening cabinet drawer, wherein when the drawer door is slanted to its maximum opening angle, the pull rod mechanism is in a locked state. This effectively prevents the drawer door from being pulled back to a certain angle or completely closed by the elastic force of the internal elastic pull member when the operator is taking items into the drawer. This ensures the convenience of taking items into the drawer and significantly improves the user experience.
[0028] 7. The pull-out basket is magnetically attached to the inclined surfaces of the left and right slanted door pull rod mechanisms by magnets, so that the pull-out basket can be pulled out together when the drawer is pulled out, realizing the hidden linkage effect of the pull-out basket and the drawer, and ensuring the convenience of dual operation when taking items out of the drawer and the pull-out basket.

[0062] This utility model discloses a slanted opening mechanism for a cabinet drawer, wherein the pull rod mechanism has two states: unlocked and locked. When the drawer door is slanted open to retrieve or place items, the pull rod mechanism is in the locked state, thereby locking the drawer door at its maximum opening angle. This effectively prevents the drawer door from closing at a certain angle or completely closing under the elastic force of the internal elastic member when the operator is retrieving or placing items inside the drawer, ensuring convenient operation when retrieving or placing items. After retrieving or placing items, the operator only needs to apply a certain pushing force to the rear of the drawer door to change the pull rod mechanism from the locked state to the unlocked state. The drawer door will then gradually close and return to its original position under the elastic return force of the elastic member, significantly improving the user experience.
[0063] Example 2
[0064] like Figures 15-17 As shown, a slanted door cabinet drawer includes a drawer 1, a drawer door panel 3, and a bottom plate 6. A slanted door pull rod mechanism 5 is respectively installed on the inner side of the two side panels 2 on the left and right sides of the drawer 1. The slanted door pull rod mechanism 5 is a slanted door mechanism for cabinet drawers as described in Embodiment 1. The lower end of the drawer door panel 3 is hinged to the front end of the bottom plate 6 through a hinge 4. The left and right sides of the drawer door panel 3 are respectively fixedly connected to the connecting seat 5-2a on the corresponding slanted door pull rod mechanism 5.
[0065] Preferably, the drawer also includes a pull-out basket 7 slidably mounted on the rear side above the drawer 1. The pull-out basket 7 is located at the notch slot K of the left and right diagonal door pull rod mechanisms 5. The front side of the pull-out basket 7 has a front inclined plate 7-1 that corresponds to and fits against the inclined surface L of the left and right diagonal door pull rod mechanisms 5. Both ends of the front inclined plate 7-1 are equipped with magnets 7-2 that correspond to magnets 5-5 on the left and right diagonal door pull rod mechanisms 5. The pull-out basket 7 is magnetically attracted and fixed to the inclined surface L of the left and right diagonal door pull rod mechanisms 5 by magnets 7-2. A storage box 8 is installed on the inner side of the drawer door panel 3.
[0066] Specifically, depending on the actual usage, a diagonal door pull rod mechanism 5 can be selectively installed on the left or right side panel 2 of drawer 1 to satisfy the diagonal door opening function of drawer 1.
[0067] The working principle of a slanted door cabinet drawer in Example 2:
[0068] The hinge point between connecting seat 5-2a and the front end of pull rod 1 5-2b is denoted as hinge point A; the hinge point between the rear end of pull rod 1 5-2b and the front end of pull rod 2 5-2c is denoted as hinge point B; one end of the rear pin 5-2d-4 of connecting block 5-2d is movably inserted into the pin hole J and is denoted as hinge point C (see Appendix). Figure 9 ).
[0069] Step 1: The initial state is marked by the drawer door panel 3 being perpendicularly attached to the front end of the side panel 2 of drawer 1. When it is necessary to take out or put in items, the operator holds the drawer door panel 3 and applies a certain pulling force forward, causing the drawer door panel 3 to gradually flip to its maximum opening angle. During this process, the drawer door panel 3 flips forward and downward with hinge point A as the fulcrum, the rear end of pull rod 1 5-2b flips forward and downward with hinge point B as the fulcrum, and pull rod 2 5-2c moves forward to its limit position. At this time, the front end of connecting block 5-2d rotates forward and downward with the rear hinge point C as the fulcrum, so that the lower left end of protrusion 1 5-2c-1 and the upper right end of protrusion 4 5-2d-2 form a dead contact point D (see Appendix). Figure 10 and attached Figure 11 At this time, the lever mechanism 5-2 is in the locked state;
[0070] Step 2: After placing or removing items from drawer 1, the operator holds drawer door 3 and applies a certain pushing force F to the rear, so that the lower left end of protrusion 1 5-2c-1 separates from the upper right end of protrusion 4 5-2d-2 and abuts against protrusion 3 5-2d-1 to form abutment point E (see appendix). Figure 12 and attached Figure 13 At this time, the lever mechanism 5-2 changes from the locked state to the unlocked state. The operator can continue to apply a backward pushing force to close the drawer door panel 3, or release the drawer door panel 3. Under the elastic reset pulling force of the elastic tension member 5-2f, the drawer door panel 3 will continue to move backward and be sucked back until it abuts against the front end surface of the side panel 2 of the drawer 1 again.
[0071] Step 3: When you need to take items out of the pull-out basket 7, pull the drawer 1 out to the outside of the cabinet. The pull-out basket 7 will move to the outside of the cabinet along with the drawer 1. After taking out or putting in items, push the drawer 1 to the back and store it inside the cabinet.
[0072] This utility model discloses a slanted-opening cabinet drawer. When the drawer door is slanted to its maximum opening angle, the pull rod mechanism is locked. This effectively prevents the drawer door from closing at a certain angle or completely closing under the elastic pull of the internal elastic member when the operator is taking items out of the drawer. This ensures the convenience of taking out and putting in items and significantly improves the user experience.
[0073] 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.
