Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a drawer structure. Background Technology

[0002] Most standing desks on the market use a single, solid tabletop as the desktop, resulting in a relatively simple overall design. However, to maintain a clean and aesthetically pleasing look, traditional drawers cannot be incorporated, thus negating the desk's storage function. Conversely, placing drawers under the tabletop would be too obtrusive, and the pull-out mechanism requires the drawer to protrude vertically from under the tabletop, increasing installation difficulty and adding to the tabletop's vertical volume. This makes it easier for users to scratch or bump the drawer, affecting usability, as illustrated by patent CN202121406422.0.

[0003] Some height-adjustable desks alleviate the above problems by reducing the height of the drawers, but this makes it impossible to fit larger items in the drawers; moreover, the sliding mechanism of the drawers requires a matching plate for installation, and the matching plate also needs to be fixed under the tabletop, which takes longer to install and is less efficient, as shown in patent CN201820656057.0. Summary of the Invention

[0004] To solve the aforementioned technical problems, this utility model provides a drawer structure, including a crossbeam, a storage box, a rod, a sliding support, and a tabletop. A rod is installed on the crossbeam below the tabletop, and a sliding support is installed on the rod, with the two slidably connected. The storage box is installed on the sliding support. Pulling out the sliding support exposes the storage box on the tabletop or retracts it into the tabletop. The storage box includes an elastic fabric and a lower baffle. The elastic fabric can cause the lower baffle to abut against the lower part of the sliding support. The structure of the rod and the sliding support is simple, making installation easier, and it does not protrude downwards from the tabletop. The volume of the storage box changes with the expansion and contraction of the elastic fabric, allowing for the placement of large items while minimizing the space where the storage box protrudes downwards from the tabletop.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A drawer structure includes a crossbeam, a storage box, a rod, a sliding support, and a tabletop. The rod is mounted on the crossbeam and perpendicular to it. The sliding support is fitted onto the rod and slides in cooperation with it. The storage box is mounted on the sliding support and slides synchronously with it on the rod. When the storage box moves away from the crossbeam, it protrudes from the tabletop for easy access to items. When it moves closer to the crossbeam, it retracts under the tabletop to conceal the stored items. The storage box includes an elastic fabric and a lower baffle. The upper and lower ends of the elastic fabric are connected to the sliding support and the lower baffle, respectively. The elastic fabric is configured such that when no items are stored, it causes the lower baffle to rest against the lower side of the sliding support. Compared to the pull-out structure of traditional drawers, the rod and sliding support have a simpler structure, are easier to install, and do not protrude downwards from the tabletop. Compared to traditional drawers, the volume of the storage box varies with the expansion and contraction of the elastic fabric, allowing for the storage of large items while minimizing the space protruding downwards from the tabletop.

[0007] Preferably, the sliding support is a frame structure, comprising two support rods and two sleeves. The two sleeves are spaced apart horizontally, and the two support rods are spaced apart front to back, with both ends of the support rods fixedly connected to the sleeves. The upper end of the storage box is connected to both the support rods and the sleeves. The sliding support is a frame structure composed of four rods, which is simple in structure, occupies little space in the vertical direction, and is easy to slide with the rods, making installation and operation convenient and quick.

[0008] Preferably, a sleeve is fitted onto the rod, with a limiting sleeve and a sliding sleeve between the rod and the sleeve. The sliding sleeve is located at the end of the rod away from the crossbeam, and the limiting sleeve is located at the end of the rod near the crossbeam, with the sliding sleeve and limiting sleeve tightly fitted to the rod. The sliding sleeve is configured to reduce the sliding friction of the sleeve. The limiting sleeve includes a limiting ring, configured to prevent the sleeve from moving further towards the crossbeam after it abuts against the limiting ring. The inner diameter of the sleeve is larger than the diameter of the rod, and the inner diameter of the sleeve is equal to the diameter of the sliding sleeve. The sleeve and the sliding sleeve slide against each other, thereby reducing the contact area and reducing sliding friction, making the drawer easier and smoother to pull out. The diameter of the limiting ring of the limiting sleeve is larger than the inner diameter of the sleeve, so the limiting ring will block the sleeve, thereby achieving the limiting function.

[0009] Preferably, the rod is connected to the crossbeam via a mounting base. The mounting base includes a detachably connected front plate and a rear plate, which are spaced apart, and the crossbeam is positioned between the front and rear plates. The mounting base has a simple structure, and the front and rear plates are detachably connected. Therefore, when installing the mounting base and the rod, it is not even necessary to remove the tabletop, making the storage box a component that can be installed voluntarily.

[0010] Preferably, protrusions are provided on the front and rear panels. The protrusions thicken the front and rear panels to increase structural strength and extend service life.

[0011] Preferably, the upper end of the front plate extends rearward to form a connecting portion with an insertion hole; the upper end of the rear plate has a matching insertion portion with a matching insertion hole; the lower end of the front plate bends rearward, and after the insertion portion of the rear plate is inserted into the insertion hole of the front plate, the lower end of the front plate and the lower end of the rear plate are connected by bolts. The connecting portion is mounted on a crossbeam, and the lower end of the front plate bends rearward to abut against the edge of the crossbeam, thus locking the mounting base and the crossbeam together, preventing the rods, sliding supports, and storage bags on them from tipping over and falling off.

[0012] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0013] Compared to the pull-out mechanism of traditional drawers, the rod and sliding support structure is simpler, easier to install, and does not protrude downwards from the tabletop. Compared to traditional drawers, the volume of the storage box changes with the stretching and contraction of the elastic fabric, allowing for the placement of large items while minimizing the space where the storage box protrudes downwards from the tabletop.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] The specific implementation of this utility model is as follows:

[0027] like Figure 1-3 As shown, this utility model provides a drawer structure, including a crossbeam 1, a storage box 2, a rod 3, a sliding support 4, and a tabletop 5. The crossbeam 1 is installed below the tabletop 5, the rod 3 is installed on the crossbeam 1 and is perpendicular to the crossbeam 1, the sliding support 4 is sleeved on the rod 3 and slides in cooperation with the rod 3, and the storage box 2 is installed on the sliding support 4 and slides synchronously on the rod 3. When the storage box 2 moves away from the crossbeam 1, the storage box 2 protrudes from the tabletop 5 to take out and put in items. When the storage box 2 moves closer to the crossbeam 1, the storage box 2 retracts to below the tabletop 5 to hide the stored items. The storage box 2 includes an elastic fabric 21 and a lower baffle 22. The upper and lower ends of the elastic fabric 21 are connected to the sliding support 4 and the lower baffle 22, respectively. The elastic fabric 21 is configured such that when no items are stored, it drives the lower baffle 22 to abut against the lower side of the sliding support 4.

[0028] Compared to the pull-out mechanism of traditional drawers, the structure of the rod 3 and the sliding support 4 is simpler, easier to install, and will not protrude downwards from the tabletop 5. Compared to traditional drawers, the volume of the storage box 2 changes with the stretching and contraction of the elastic fabric 21, which can accommodate large items while minimizing the space where the storage box 2 protrudes downwards from the tabletop 5.

[0029] Specifically, such as Figure 4 , 5As shown, this drawer structure can be used in a height-adjustable desk. In the desk, the tabletop 5 is supported by two crossbeams 1, spaced apart at the front and back below the tabletop 5. Each crossbeam 1 is arranged along the length of the tabletop 5. The crossbeams 1 are installed below the tabletop 5, and the storage box 2, like the crossbeams 1, is located below the tabletop 5. The storage box 2 is open at the top. When the storage box 2 is retracted below the tabletop 5, the tabletop 5 can close the storage box 2. When the front of the storage box 2 protrudes forward from the tabletop 5, the storage box 2 is partially open, allowing items to be placed in and out. There are two rods 3, spaced apart on the crossbeams 1, and the rods 3 are arranged along the front and back direction, serving as a track for the storage box 2 to move. Figure 2 , 3 As shown in Figure 6, the rod 3 is connected to the crossbeam 1 via the mounting base 6. The mounting base 6 includes a front plate 61 and a rear plate 62 that are detachably connected. The front plate 61 and the rear plate 62 are spaced apart, and the crossbeam 1 is located between the front plate 61 and the rear plate 62. The mounting base 6 has a simple structure, and the front plate 61 and the rear plate 62 are detachably connected. Therefore, when installing the mounting base 6 and the rod 3, it is not even necessary to remove the tabletop 5, making the storage box 2 a component that can be installed by the user.

[0030] like Figure 2 , 3 As shown in Figures 6 and 8, the upper end of the front plate 61 extends rearward to form a connecting portion 63, on which an insertion hole 64 is provided. The upper end of the rear plate 62 has an insertion portion 65 that matches the insertion hole 64. The lower end of the front plate 61 bends rearward, and after the insertion portion 65 of the rear plate 62 is inserted into the insertion hole 64 of the front plate 61, the lower end of the front plate 61 and the lower end of the rear plate 62 are connected by bolts. The connecting portion 63 is mounted on the crossbeam 1, and the lower end of the front plate 61 bends rearward to abut against the edge of the crossbeam 1, so that the mounting base 6 and the crossbeam 1 are locked together, preventing the rod 3 and the sliding support 4 and the storage bag on it from tipping over and falling off. Due to the structure of the mounting base 6, the mounting... The seat 6 is detachable, meaning the storage bag can be selectively installed under the tabletop 5 without removing the tabletop 5 and directly connected to the crossbeam 1. During installation, the front plate 61 moves from front to back so that the connecting part 63 is on the crossbeam 1, and the insertion hole 64 is exposed to the rear of the crossbeam 1. The rear plate 62 moves from bottom to top so that the insertion part 65 is inserted into the insertion hole 64. The lower end of the rear plate 62 and the lower end of the front plate 61 have openings for bolts to pass through, so that the lower end of the rear plate 62 and the lower end of the front plate 61 are aligned and connected by bolts. The front plate 61 and the rear plate 62 are provided with protrusions 66 to increase structural strength and extend service life.

[0031] Furthermore, such as Figure 1 , 6As shown in Figure 7, the sliding support 4 is a frame structure, comprising two support rods 41 and two sleeves 42. The two sleeves 42 are spaced apart horizontally, and the two support rods 41 are spaced apart front to back, with both ends of the support rods 41 fixedly connected to the sleeves 42. The upper end of the storage box 2 is connected to the support rods 41 and the sleeves 42 respectively. The sliding support 4 is a frame structure composed of four rods 3, which is simple in structure and occupies little space in the vertical direction. It is easy to slide and cooperate with the rods 3, and is convenient and quick to install and operate. The sleeves 42 are sleeved on the rods 3. A limiting sleeve 7 and a sliding sleeve 8 are provided between the rods 3 and the sleeves 42. The sliding sleeve 8 is located at the end of the rod 3 away from the crossbeam 1, and the limiting sleeve 7 is located at the end of the rod 3 near the crossbeam 1. The sliding sleeve 8 and the limiting sleeve 7 are connected. Sleeve 7 is tightly fitted with rod 3; sliding sleeve 8 is configured to reduce sliding friction of sleeve 42; limiting sleeve 7 includes limiting ring 71 and transition platform (labeled) located at the front end of limiting sleeve 7. The transition platform is configured with a diameter that gradually increases from back to front so that the sleeve can easily return to limiting sleeve 7 after it is disengaged from 42. The limiting sleeve 7 is configured to prevent sleeve 42 from continuing to approach beam 1 after it abuts against limiting ring 71; the inner diameter of sleeve 42 is larger than the diameter of rod 3, and the inner diameter of sleeve 42 is equal to the diameter of sliding sleeve 8. Sleeve 42 and sliding sleeve 8 slide against each other, thereby reducing the contact area and reducing sliding friction, making the drawer easier and smoother to pull out; the diameter of limiting ring 71 of limiting sleeve 7 is larger than the inner diameter of sleeve 42, so limiting ring 71 will block sleeve 42, thereby achieving the limiting function.

[0032] like Figure 4 , 5 As shown, the elastic fabric 21 is elastic and is located between the sliding support 4 and the lower baffle 22. The sliding support 4 expands the elastic fabric 21, so that the drawer structure has an opening. The lower baffle is equivalent to the bottom of the drawer structure and is used to support items. When items enter the storage box 2, the elastic fabric 21 will deform due to the weight of the items, and the lower baffle 22 will sink. In addition, since the elastic fabric 21 is elastic, the storage box 2 can adapt to the volume of the items.
