[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example 1

[0053] like Figures 1-10 As shown, an embodiment of the present invention provides a retractable cabinet structure, comprising:

[0054] The box 1 is split into a front box 11 and a rear box 12;

[0055] The walls of the front box 11 and the rear box 12 are provided with mutually cooperating convex and concave grooves 13;

[0056] The convex and concave grooves 13 are internally provided with a locking adjustment mechanism 14;

[0057] Through the cooperation of the convex and concave grooves 13, the front box 11 and the rear box 12 can be relatively telescoped to adjust the depth of the box 1;

[0058] By operating the locking adjustment mechanism 14, the front box 11 and the rear box 12 can be selectively locked or released.

[0059] The traditional integrated box 1 is split into two independent parts, the front box 11 and the rear box 12, which are embedded and guided through the mutually cooperating convex and concave grooves 13 provided on their walls. The locking adjustment mechanism 14 is the key to connecting and fixing the two boxes 1, which is integrated inside the convex and concave grooves 13. When adjustment is needed, the mechanism is operated to release it, and the box 1 can be telescoped along the track of the convex and concave grooves 13. When the adjustment is in place, the mechanism is operated to lock it, and the two parts of the box 1 are tightly fixed as a rigid whole.

[0060] The depth of the box 1 is flexibly variable, solving the pain point that fixed-size cabinets cannot adapt to various space scenarios. When transporting and storing, it can be contracted to the smallest volume, greatly saving logistics and storage costs. After delivery to the user, it can be expanded to the appropriate size according to the actual space requirements, meeting the personalized and customized needs of customers, and realizing "one cabinet for multiple uses".

[0061] As shown in the drawings, Figures 1-10 In some embodiments, the convex and concave grooves 13 are also provided with a slide rail 15.

[0062] The slide rail 15, as a kinematic pair, together with the convex and concave grooves 13 forms a double-guiding system. The addition of the slide rail 15 greatly improves the smoothness and stability of the telescoping process of the box 1, avoiding the possible jamming and wear when relying solely on the sliding of the convex and concave grooves 13. It bears the main sliding friction, ensuring a light and smooth telescoping experience, and prolonging the service life of the convex and concave grooves 13, making the product more durable and reliable.

[0063] As shown in the drawings, Figures 1-10 In some embodiments, the front box 11 is slidably sleeved inside the rear box 12;

[0064] The convex and concave groove 13 comprises a front box concave groove 131 arranged on both sides of the front box 11, and a rear box convex groove 132 arranged on the inner wall of the rear box 12, the rear box convex groove 132 is correspondingly sleeved in the front box concave groove 131.

[0065] The front box 11 is sleeved in the rear box 12 in a smaller size to realize telescoping, and the convex and concave groove 13 is specifically defined as the front box concave groove 131 (a groove recessed inward) arranged on both sides of the front box 11, and the rear box convex groove 132 (a groove protruding inward) arranged on both sides of the inner wall of the rear box 12, which are precisely matched in the form of “concave groove sleeving convex groove”.

[0066] The structure of “inner box sleeving outer box” and “concave groove sleeving convex groove” ensures that the box 1 is always well constrained during telescoping, and cannot shake left and right or derail, and at the same time, it hides all the sliding structures inside the box 1, and the appearance is neat.

[0067] As shown in the drawings, Figures 1-10 In some embodiments, the locking and adjusting mechanism 14 comprises a screw sliding block 141 and a connecting screw 142;

[0068] The screw sliding block 141 is slidably arranged in the rear box convex groove 132;

[0069] The front box concave groove 131 is provided with a connecting hole 143, and the rear box convex groove 132 is provided with a first waist-shaped hole 144;

[0070] The connecting screw 142 is screwed into the screw sliding block 141 after passing through the connecting hole 143 and the first waist-shaped hole 144 in sequence, and the locking and loosening of the box 1 is realized by tightening or loosening the connecting screw 142.

[0071] The screw sliding block 141 (slidable in the rear box convex groove 132) and the connecting screw 142 are arranged, the connecting screw 142 passes through the connecting hole 143 on the front box concave groove 131 and the first waist-shaped hole 144 on the rear box convex groove 132 in sequence, and is finally screwed into the screw sliding block 141, when tightened, the screw sliding block 141 and the inner wall of the rear box convex groove 132 and the wall surface of the front box concave groove 131 are pressed tightly to generate a large friction force to realize locking; when loosened, the pressure disappears, the screw sliding block 141 can slide along the first waist-shaped hole 144 to realize stepless adjustment.

[0072] By simply screwing, the state can be switched between “flexible sliding” and “rigid fixing”, the first waist-shaped hole 144 provides a continuous and stepless stroke for adjustment, so that the depth of the box 1 can be fixed at any position, the adjustment accuracy is high, the whole mechanism structure is simple, the cost is low, and the operation is extremely convenient.

[0073] As shown in the drawings, Figures 1-10As shown, in some embodiments, the slide rail 15 includes a slide rail 151 fixed in the groove 131 of the front housing and a fixed rail 152 fixed on the rear housing 12, wherein the slide rail 151 and the fixed rail 152 are slidably connected.

[0074] Both the fixed rail 152 and the sliding rail 151 are U-shaped, and the top and bottom of the sliding rail 151 are bent to form grooves for installing sliding components (such as steel balls).

[0075] The slide rail 15 is divided into a sliding rail 151 (fixed in the groove 131 of the front box) and a fixed rail 152 (fixed on the rear box 12). The two are connected by a U-shaped structure to achieve sliding. Specifically, the sliding rail 151 is placed below the protrusion 132 of the rear box, making full use of the extra space in the groove 131 of the front box.

[0076] The slide rail 15 is hidden inside the groove 13 structure, which does not take up extra space and has a compact layout. The U-shaped slide rail 15 is fitted with the sliding parts (such as steel balls) inside it, which greatly reduces the coefficient of sliding friction, making the extension and retraction action more effortless, smooth and quiet, and enhancing the product’s premium feel and user experience.

[0077] like Figures 1-10 As shown, in some embodiments, the upper part of the front housing groove 131 and the rear housing protrusion 132 are in contact with each other to support the weight of the sliding housing 1.

[0078] The upper parts of the front housing groove 131 and the rear housing protrusion 132 are in contact with each other, which means that when the housing 1 extends or retracts, the upper contact surfaces of the groove 13 will support each other, so that the groove 13 structure can directly bear part of the weight of the front housing 11 and its internal load, forming a dual load-bearing mechanism (part of the weight is borne by the slide rail 15, and part is borne by the upper contact surface of the groove 13). This effectively prevents the entire weight and load of the housing 1 from pressing on the slide rail 15 for a long time, avoids the slide rail 15 from deforming due to overload, and significantly improves the reliability and service life of the entire structure.

[0079] like Figures 1-10 As shown, in some embodiments, an extendable shelf 16 is also included, which is movably disposed inside the housing 1.

[0080] The extendable shelf 16 includes a front shelf portion 161 and a rear shelf portion 162;

[0081] The front shelf portion 161 and the rear shelf portion 162 are connected by a shelf locking assembly 163. The shelf locking assembly 163 includes a second oblong hole 1631 opened on one of the shelf portions and a shelf screw 1632 passing through the second oblong hole 1631 and threadedly connected to the other shelf portion.

[0082] By loosening the shelf screw 1632, the front shelf part 161 and the rear shelf part 162 can slide relative to each other to adjust the length of the extendable shelf 16.

[0083] By tightening the shelf screw 1632, the front shelf part 161 and the rear shelf part 162 are fastened as a whole.

[0084] To solve the problem of adapting the internal shelf when the box 1 is extended or retracted, the extendable shelf 16 is designed, which has two installation modes. One is that the extendable shelf 16 is movably arranged in the box 1, which can be supported by the installation screw gap 17, facilitating the user to adjust its position flexibly, and the extendable shelf 16 can also be removed or increased according to the space layout. The other is that the extendable shelf 16 is composed of a front shelf part 161 and a rear shelf part 162 fixed to the front and rear boxes 12 respectively, and the two are connected by a shelf locking assembly 163 (second waist-shaped hole 1631 and shelf screw 1632). This structure ensures that the length of the extendable shelf 16 can be adjusted synchronously with the change of the depth of the box 1, maintains the functional integrity of the internal space of the box 1, and the user does not need to replace the shelf because the depth of the box 1 is adjusted, improving the functionality and convenience of the product. Its adjustment and locking principle is consistent with the box 1 main body, the operation logic is unified, and the user is easy to understand and master.

[0085] As shown in Figures 1-10 In some embodiments, the front box 11 is provided with a mounting screw gap 17 recessed into the box 1.

[0086] The rear box 12 is provided with a fixing hole 18 corresponding to the position of the mounting screw gap 17.

[0087] The mounting screw gap 17 provides a space for accommodating the head of the screw for fixing the box 1 to the wall (or other position) from the outside. This design ensures that even when the box 1 is in the retracted state, the head of the mounting screw will not protrude to hinder the sliding of the front box 11, realizing the perfect mutual non-interference of the installation function and the extension function, and integrating the function of supporting the extendable shelf 16. The extendable shelf 16 can be placed on the mounting screw gap 17.

[0088] As shown in Figures 1-10 In some embodiments, the convex and concave grooves 13 are reversely protruded from the inner wall of the box 1, forming a support structure for the extendable shelf 16.

[0089] By reversing the protrusion of the convex and concave groove 13 in the inner wall of the box 1, a protruding step or rib is formed inside the box 1, without the need for additional installation of support bars or brackets, simplifying the structure, reducing the number of parts and assembly cost; this embodies the design philosophy of "one thing for multiple purposes", making the convex and concave groove 13 not only bear the guiding and bearing functions, but also integrate the function of supporting the extendable shelf 16 consistent with the installation screw clearance groove 17, greatly optimizing the overall design.

[0090] As shown in Figures 1-10 some embodiments, the convex and concave groove 13 and the locking and adjusting mechanism 14 can be at least one group or a combination thereof; based on the same principles 1-8 above, the relative positions of the front box 11 and the rear box 12 and the front shelf part 161 and the rear shelf part 162 can be changed, and the inner and outer convex directions of the convex and concave groove 13 can also be changed.

[0091] A telescopic method of a telescopic cabinet, comprising the following steps:

[0092] S1, loosen the locking mechanism, unscrew the connecting screw 142 in the locking and adjusting mechanism 14 and the shelf screw 1632;

[0093] S2, stepless adjustment of the box 1, when the connecting screw 142 and the shelf screw 1632 are both in the unscrewed state, the front box 11 and the rear box 12 are relatively slid by the cooperation of the convex and concave groove 13 and the slide rail 15, so that the stepless adjustment of the depth size of the box 1 in the telescopic range is realized;

[0094] S3, fastening and locking of the box 1, when the depth of the box 1 reaches the required size, the connecting screw 142 and the shelf screw 1632 are tightened, so that the front box 11 and the rear box 12 are fastened as a whole;

[0095] S4, telescopic split body installation into the wall, after the screw is loosened in S1, the split body can also be completely unscrewed, which facilitates the installation of the rear box 12 into the wall without interference from the front box 11, after the rear box 12 is installed into the wall, the front box 11 is sleeved in the rear box 12 through the cooperation of the convex and concave groove 13 and the slide rail 15, the screw block 141, the connecting screw 142, the extendable shelf 16 and the shelf screw 1632 are installed, and after the depth is adjusted to the required position, the connecting screw 142 and the shelf screw 1632 are tightened, the front box 11 and the rear box 12 are fastened as a whole, and the installation and telescoping are completed.

[0096] Example two

[0097] As shown in Figures 1-11 , an embodiment of the present application proposes a manufacturing and assembly process of a telescopic cabinet, which is efficient and easy to implement, can ensure the stability of the cabinet structure and the smoothness of the telescoping, and comprises the following steps:

[0098] S1, box 1 split and convex and concave groove 13 forming, first, the box 1 split into front box 11 and rear box 12 two main parts to be manufactured separately; the core of the design is to meet the different functions and aesthetic needs of the front and rear box 12, using differentiated manufacturing processes;

[0099] Front box 11 functional manufacturing: front box 11 as a moving part, its two side walls are made of sheet metal through stamping and bending process, the front box groove 131 and the mounting screw clearance groove 17 are integrally formed; the groove directly serves as a telescopic guide and bearing structure, taking into account the structural strength and production efficiency;

[0100] Rear box 12 aesthetic manufacturing: to ensure that the rear box 12 as the main appearance surface presents a neat appearance of four square and four right, the surface without depression, the rear box convex groove 132 adopts the process of split processing and then welding, that is, the rear box convex groove 132 is made as an independent component, and then welded to the inner wall of the rear box 12 on both sides from the inside. This cleverly hides all functional structure grooves inside the box 1, realizing the internal necessary guide and connection function without sacrificing the external appearance;

[0101] Structural reinforcement design: regardless of the process, the forming position of the convex and concave groove 13 is designed as the splicing and reinforcement position of the side wall of the box 1, which significantly enhances the overall structural rigidity;

[0102] S2, integration and installation of functional structure,

[0103] Shelf support structure integration: when the convex and concave groove 13 is bent, it protrudes reversely into the box 1, thereby naturally forming a support structure for supporting the extendable shelf 16 in the box;

[0104] Slide rail 15 installation: the U-shaped slide rail 151 is fixed to the inner side of the bottom of the front box concave groove 131 by screw or riveting, and the corresponding U-shaped fixed rail 152 is fixed to the rear box 12, ensuring that the slide rail 151 and the fixed rail 152 can be precisely fitted and smoothly slide.

[0105] Locking mechanism installation: the screw block 141 is loaded into the internal cavity of the rear box convex groove 132 from the rear or side, so that it can slide freely inside; then, using the connecting screw 142, pass through the pre-set connecting hole 143 on the front box concave groove 131 and the pre-set first waist-shaped hole 144 on the rear box convex groove 132 in turn, and finally screw into the screw block 141, but not completely tightened;

[0106] S3, box 1 set and dynamic assembly: the front box 11 with the sliding rail 151 installed is slowly inserted into the inside of the rear box 12 by aligning the front box groove 131 with the rear box protrusion 132; during this process, ensure that the sliding rail 151 and the fixed rail 152 are accurately connected, and the preliminary assembly of the box 1 is completed;

[0107] S4, installation of auxiliary components,

[0108] Extensible shelf 16 assembly: the fixed extensible shelf 16 divides the extensible shelf 16 into a front shelf part 161 connected to the front box 11 and a rear shelf part 162 connected to the rear box 12; a second waist-shaped hole 1631 is formed on one of the shelf parts, and then a shelf screw 1632 is used to pass through the second waist-shaped hole 1631 to connect with the other shelf part, realizing the telescopic function of the shelf itself;

[0109] Adjust the movable extensible shelf 16 and directly select the installation screw clearance groove 17 or the convex-concave groove 13;

[0110] Final fixation: drill holes on the rear box 12 corresponding to the positions of the installation screw clearance groove 17 to form the fixing hole 18, so that the user can fix the entire cabinet to the wall later;

[0111] S5, layout adjustment and modification (optional step), according to the different size and load-bearing requirements of the cabinet, the layout of the above structure can be adaptively adjusted during the design stage; for example, the number of convex-concave grooves 13 and sliding rails 15 can be increased or decreased (such as from two groups on each side to two groups on each side); the setting position can also be adjusted, for example, the convex-concave groove 13 and the sliding rail 15 are arranged on the outside of the box 1 instead of the inside, to meet different structural strength and aesthetic requirements.

[0112] In summary, by splitting the box 1 into a front box 11 and a rear box 12, and setting the convex-concave groove 13 and the internal sliding rail 15 and locking adjustment mechanism 14 on the wall surface, the depth of the box 1 is adjusted steplessly within the telescopic range, which can save cost with the smallest volume during transportation and storage, and the customer can adjust the depth and tighten according to the actual space requirement after delivery, meeting the individual needs of different scenarios, while the double-guiding system composed of the convex-concave groove 13 and the sliding rail 15 and the adjustable extensible shelf 16 ensure the stability and smoothness of the telescopic process and the integrity of the internal space, realizing an integrated solution from intensive transportation to customized use.
