Description

Technical Field

[0001] This utility model relates to the field of home storage tools, and in particular to a push-pull storage rack. Background Technology

[0002] As a core tool for home organization, shelving units efficiently utilize space, rationally arrange the living environment, and make it more tidy and orderly. For example, the Chinese utility model patent CN220734813U, entitled "A Pull-out Shelving Unit," includes a pull-out assembly, a second shelf, a first limiting mechanism, a second limiting mechanism, a suction cup, and a support rod. The pull-out assembly includes a base and a first shelf. The first shelf can move laterally relative to the base. The base is equipped with a first set of rollers, and the first shelf has a second set of rollers. During the movement of the first shelf relative to the base, the top of the first roller in the first set always contacts the bottom of the first shelf, and the bottom of the second roller in the second set always contacts the upper surface of the base. Through the cooperation of the first and second roller sets with the base and the first shelf, the rollers reduce friction when the shelf is pulled out, making it easy and effortless to pull out. Furthermore, the sliding parts are covered and hidden by the first shelf, increasing its aesthetic appeal.

[0003] However, the existing technology still has the following drawbacks:

[0004] Existing shelving units use rollers and a base for pull-out shelves, resulting in a complex assembly structure that increases manufacturing costs, maintenance difficulty, and overall weight, failing to meet users' more refined daily needs. Furthermore, the rollers can only be installed on the base, preventing flexible vertical layering and expansion of shelf numbers, thus limiting daily usability and storage space. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a push-pull storage rack.

[0006] The purpose of this utility model is achieved by the following technical solution: a push-pull shelf, comprising a support body, guide rails, and a push-pull tray. The support body has a first side frame and a second side frame, which are correspondingly arranged on the left and right sides of the push-pull tray. The guide rails have guide sections and hook sections, with the hook sections located at both ends of the guide sections. Several guide rails are detachably and layered in the vertical direction of the first and second side frames via the hook sections at both ends. The push-pull tray has sliding grooves along its left and right sides, which engage with the guide sections of the guide rails to install several layers of push-pull trays within the support body according to the layer spacing of the guide rails.

[0007] Furthermore, the guide rail also has a limiting section, which is disposed at both ends of the guide section and perpendicular to the end of the guide section, and is used to limit the stroke of the push-pull tray as it is pulled outward and pushed inward.

[0008] Furthermore, a limiting block is provided in the sliding groove of the push-pull basin, which is used to abut against the limiting section at the front end of the guide rail rod when the push-pull basin is pulled outward, or to abut against the limiting section at the rear end of the guide rail rod when the push-pull basin is pushed inward.

[0009] Furthermore, the front end of the sliding groove of the push-pull basin is provided with a front stop, which is used to contact the limiting section of the front end of the guide rail rod when the push-pull basin is pushed inward.

[0010] Furthermore, the inner sides of the first and second side frames of the bracket body are provided with a number of hook holes according to the height of the guide rail layer. The limiting section is also connected to the hook section, and the hook section is bent inward from the end of the limiting section for detachable hooks in the hook holes.

[0011] Furthermore, the rim of the push-pull basin is provided around the basin opening, and the sliding groove is formed by the concave part of the rim of the push-pull basin on the left and right sides.

[0012] Furthermore, a handle is provided on the outer edge of the front side of the push-pull basin.

[0013] Furthermore, the first side frame and the second side frame are respectively provided with an upper side frame and a lower side frame, and the connecting ends of the upper side frame and the lower side frame are connected by an embedded U-shaped groove plate.

[0014] Furthermore, a hanging plate is installed on the outer side of the upper frame, and a plurality of hanging holes are arranged in an array on the hanging plate.

[0015] Furthermore, the support body also has a base frame, the lower side frame is mounted on the base frame, and the base frame is also equipped with swivel casters.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: In the embodiments of this application, multiple guide rail rods are detachably installed on the inner side of the first / second side frame of the bracket body, and the multiple guide rail rods are hooked to the inner side of the first / second side frame through hook sections to form a multi-layer horizontal support track. The push-pull tray is fitted into the guide section of the guide rail rod through the sliding groove integrally set on the left and right sides to realize the horizontal pull-out function.

[0017] This application provides a quick-release structure for the slide rail and guide rail, replacing the traditional pull-out structure of the complex roller system, reducing the use of accessories, simplifying the assembly structure, reducing the overall weight of the shelf, and allowing damaged parts of the guide rail or push-pull tray to be replaced individually, facilitating daily moving and maintenance. The guide rail is a fixed accessory, reducing the cost of mold manufacturing.

[0018] Furthermore, by using the hook sections of the guide rails to quickly install and remove the first / second side frames, the number of guide rails can be flexibly increased or decreased, thereby supporting flexible configuration of the number of layers in the sliding basin, flexibly adjusting the size of the storage space, and expanding application scenarios.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] like Figure 1-8 As shown, a push-pull storage rack is a modular, layered, and expandable rack that efficiently utilizes space, rationally arranges the living environment, and makes the environment more tidy and orderly. The push-pull storage rack includes a support body 10, guide rails 20, and a push-pull tray 30. The support body 10 has a first side frame 101, a second side frame 102, and a base frame 103. The first side frame 101 and the second side frame 102 are arranged parallel and opposite to each other on the base frame 103, forming the support frame of the storage rack. Furthermore, the four corners of the base frame 103 are equipped with braked swivel casters 50, enabling the entire storage rack to move and adapt to various layout adjustments.

[0035] like Figure 3-4 As shown, more specifically, the first side frame 101 provided in this embodiment is divided into an upper side frame 1021 and a lower side frame 1022. Similarly, the second side frame 102 is also divided into an upper side frame 1021 and a lower side frame 1022. During installation, the lower side frame 1022 of the first side frame 101 and the second side frame 102 is welded onto the base frame 103. In addition, the upper end of the lower side frame 1022 and the lower end of the upper side frame 1021 are fixed by inserting a U-shaped groove plate 105 and bolts, completing the longitudinal assembly between the upper and lower side frames 1022, thus forming the first and second side frames 102. The U-shaped groove plate 105 used can be replaced with a quick-release buckle structure, saving parts and realizing tool-free rapid assembly.

[0036] A horizontally arranged top plate 106 can be installed on the top of the upper side frame 1021 of the first / second side frame 102. This plate can serve as a dustproof cap and also to reinforce the connection strength between the upper side frames 1021 of the first / second side frame 102.

[0037] like Figure 5-7 As shown, the guide rail 20 provided in this embodiment has a guide section 201, a limiting section 202, and a hook section 203. The guide section 201 serves as a straight guide in the middle of the guide rail 20. The limiting sections 202 are located at both ends of the guide section 201. The hook section 203 is perpendicularly bent at the end of the guide section 201, forming a right-angle connection with the guide rail section. During daily use of the push-pull tray 30, the limiting section 202 acts as a physical stop, restricting the outward and inward movement of the push-pull tray 30 to prevent it from derailing and improve safety.

[0038] Hook segments 203 are also located at both ends of guide segments 201, and are connected to the ends of limiting segments 202. Hook segments 203 are also bent inward from the ends of limiting segments 202, forming an acute-angle connection between hook segments 203 and limiting segments 202. Several hook holes 104 are vertically formed on the inner side of the first / second side frame 102. The diameter of the hook holes 104 is adapted to the diameter of the hook segments 203 of the guide rail rod 20. The number of hook holes 104 can be determined according to the floor height design of the guide rail rod 20.

[0039] When installing the guide rail rod 20, the end of the hook section 203 of the guide rail rod 20 can be detachably hooked into the hook hole 104 on the inner side of the first / second side frame 102 to achieve quick installation / removal of the guide rail rod 20. The acute angle design between the hook section 203 and the limiting section 202 forms a self-locking force to prevent the guide rail rod 20 from coming off under longitudinal force. Moreover, the hook installation method also makes it easy to increase or decrease the number of guide rail rods 20 in the vertical direction of the first / second side frame 102 according to the number of push-pull basins 30 installed, and supports the adjustment of the number of layers and layer height of the push-pull basins 30 as needed.

[0040] Regarding the design and installation of the push-pull basin 30, in this embodiment of the push-pull basin 30, the basin opening is folded outward to form an extended basin edge 301. The extended basin edges 301 on both the left and right sides of the push-pull basin 30 are integrally molded with grooves 3012. These grooves 3012 are recessed into the extended basin edges 301 on both sides of the push-pull basin 30 and extend along the length of the extended basin edges 301. By integrally forming the grooves 3012 on the left and right sides of the push-pull basin 30, the structural strength of the basin is enhanced, avoiding the risk of loosening caused by installing the grooves 3012 separately. The depth and width of the grooves 3012 can be designed according to the diameter of the guide rail 20, so that the cross-section of the grooves 3012 matches the shape of the guide section 201 of the guide rail 20.

[0041] When installing the push-pull basin 30, align the sliding grooves 3012 on its left and right sides with the guide rails 20 mounted on the first / second side brackets 102, and then push the push-pull basin 30 into the bracket body 10. This allows the guide sections 201 of the guide rails 20 to be embedded in the sliding grooves 3012. In other words, the first / second side brackets 102 support the left and right sides of the push-pull basin 30, completing the horizontal, layered installation of the push-pull basin 30 within the bracket body 10. The embedded fit between the sliding grooves 3012 and the guide sections 201 replaces the traditional roller assembly, reducing friction components.

[0042] Thus, the bracket body 10 provided in this application embodiment is provided with opposing and parallel first / second side frames 102, and multiple guide rail rods 20 are detachably installed on the inner side of the first / second side frames 102 respectively. The multiple guide rail rods 20 are hooked to the inner side of the first / second side frames 102 through hook sections 203 to form a multi-layer horizontal support track. The push-pull basin 30 is fitted into the guide section 201 of the guide rail rod 20 through the sliding groove 3012 integrally provided on the left and right sides to realize the horizontal pull-out function.

[0043] This application provides a quick-assembly structure for the slide rail 3012 and the guide rail 20, replacing the traditional complex roller system pull-out structure, reducing the use of accessories, simplifying the assembly structure, reducing the overall weight of the shelf, and allowing damaged parts of the guide rail 20 or the push-pull tray 30 to be replaced individually, facilitating daily moving and maintenance. The guide rail 20 is a fixed accessory, reducing the cost of mold manufacturing.

[0044] Furthermore, by using the hook section 203 of the guide rail rod 20 to quickly install and remove the first / second side frame 102, the number of guide rail rods 20 can be flexibly increased or decreased, thereby supporting the flexible configuration of the number of layers of the push-pull basin 30, flexibly adjusting the size of the storage space, and expanding the application scenarios.

[0045] like Figure 7 As shown, in order to facilitate daily use, a perforated arc-shaped handle 3011 is punched out on the outer edge 301 of the front of the sliding basin 30, which is ergonomic, reduces the user's pulling force, and makes operation more convenient.

[0046] like Figure 4-5 As shown, a hanging plate 40 is bolted to the outer side of the upper shelf 1021. The hanging plate 40 has several hanging holes 401 arranged in a rectangular, circular, or other array, and each hanging hole 401 is designed as a cross shape. By adding this hanging plate 40, hooks, S-shaped shelves, and other extension accessories can be supported to increase the vertical storage space of the shelf.

[0047] like Figure 4-5 As shown, preferably, a limiting block 30121 is integrally formed by die-stamping within the slide groove 3012 of the push-pull basin 30. This limiting block is integrally formed by protruding downwards from the upper inner wall of the slide groove 312. An insertion opening, matching the diameter of the guide rail rod 20, is provided between the end of the limiting block and the lower inner wall of the slide groove 312. Therefore, after the guide rail rod 20 is inserted into the slide groove 312, the upper inner wall of the slide groove 312 will support the guide rail rod 20. When the push-pull basin 30 slides on the guide rail rod 20, the position of its limiting block 30121 corresponds to the limiting section 202, and the side of the limiting block 30121 has an arc-shaped portion that matches the diameter of the limiting section 202.

[0048] Therefore, when the push-pull tray 30 is pulled outward to its limit position, the limiting block 30121 abuts against the limiting section 202 at the front end of the guide rail rod 20; or, when the push-pull tray 30 is pushed inward to its limit position, the limiting block 30121 abuts against the limiting section 202 at the rear end of the guide rail rod 20; thus, a physical stop is formed to prevent overturning caused by excessive pulling out or excessive pushing in, thereby improving load-bearing stability; and through the adaptation of the side arc-shaped part of the limiting block 30121 with the limiting section 202, the stopping stability of the push-pull tray 30 at the limit position is further improved.

[0049] like Figure 1-2 As shown, preferably, the sliding groove 3012 of the push-pull basin 30 has an integrally formed front stop 30122 by die stamping. Similarly, the inner side of the front stop 30122 has an arc-shaped portion adapted to the diameter of the limiting section 202. When the push-pull basin 30 slides on the guide rail 20, the position of the front stop 30122 is opposite to the limiting section 202. For example, when the push-pull basin 30 is fully pushed in, its front stop 30122 contacts the limiting section 202, forming a physical stop, preventing the push-pull basin 30 from continuing to move inward, ensuring that the push-pull basin 30 is centered, avoiding over-pushing and overturning, and further improving load-bearing stability.

[0050] The actual usage of the push-pull shelf base in this embodiment is as follows:

[0051] 1. Assembly stage

[0052] After the bracket body 10 is installed, align the hook sections 203 at both ends of the guide rail rod 20 with the hook holes 104 of the first / second side frame 102 and press them in. Install 2-5 layers as needed. Align the sliding grooves 3012 on the left and right sides of the push-pull basin 30 with the guide rail rod 20 and push them horizontally along the guide section 201 of the guide rail rod 20 until the front stop 30122 contacts the limiting section 202.

[0053] 2. Usage Phase

[0054] Hold the handle 3011 and pull the push-pull basin 30 outward. The slide 3012 slides along the guide section 201 until the limiting block 30121 in the slide 3012 stops against the limiting section 202. After placing the item, push the push-pull basin 30 inward. The front stop 30122 provides a secondary limit to ensure accurate reset.

[0055] 3. Expansion Phase

[0056] To increase the number of pull-out trays by 30 layers, simply hook the new guide rail rod 20 into the hook hole 104 at the higher position of the first / second side frame 102 and place the new pull-out tray 30 inside. The same operation can be performed when the number of pull-out trays by 30 layers needs to be reduced. To move the shelf position, step on the universal caster 50 to release the brake and push the shelf to the target area.

[0057] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
