Description

Technical Field

[0001] This utility model relates to the field of drawer divider technology, and more specifically, to a telescopic drawer divider with a spiral spring. Background Technology

[0002] Currently, drawers are used in people's daily lives in various fields, including everyday household dining tables and desks, office desks and cabinets, wardrobes for storing clothes, and other items.

[0003] As drawers serve as convenient storage containers, the amount of stored items gradually increases and becomes disorganized over time. Therefore, an auxiliary tool is needed to effectively divide drawer space; this tool is called a drawer divider.

[0004] To accommodate different drawer widths, existing technology uses retractable drawer dividers. However, to allow the retractable drawer dividers to extend and retract to any length and be fixed at any length, numerous structures are incorporated within the retractable drawer dividers to enable them to be fixed at any length.

[0005] For example, Chinese patent CN218246381U, entitled "A Retractable Drawer Divider," discloses a drawer divider structure with internal fasteners, racks, and other mechanisms to control the length of the drawer divider. This structure is complex, increasing both production and assembly costs, and requiring repeated rotation of the fasteners during use. Therefore, existing drawer dividers suffer from structural complexity, high production costs, and inconvenience in use. Utility Model Content

[0006] This invention overcomes the problems of complex structure, high production cost and inconvenience of use of existing drawer dividers; it provides a telescopic drawer divider with a spiral spring, which uses the elastic force of the spiral spring to achieve relative fixation between the two boards when the drawer divider is extended or retracted. It is not only simple in structure and easy to assemble, but also has low manufacturing cost and is convenient to use.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a telescopic drawer partition with a spiral spring, comprising a first plate and a second plate that can slide relative to each other, the spiral spring being fixedly disposed on the first plate and / or the second plate, and the first plate and the second plate being relatively fixed together by the spiral spring.

[0008] In this application, a scroll spring is installed on the second or first plate. The scroll spring's own elastic restoring force abuts against the side walls of the first and second plates, keeping the drawer divider extended. Therefore, in practical use, under the action of the scroll spring, the drawer divider is at its longest length. Depending on the drawer width, the second plate is pushed to overcome the elastic force of the scroll spring, increasing the overlap length of the first and second plates. This adjusts the drawer divider to a suitable length before it is placed inside the drawer. The elastic restoring force of the scroll spring continuously pushes the second and first plates, keeping the drawer divider extended and ensuring that both ends of the drawer divider stably abut against the inner wall of the drawer, thus dividing the space inside the drawer.

[0009] Compared to existing technologies, this application features a simple structure, primarily comprising a spiral spring, a first plate, and a second plate. During installation, the spiral spring is directly fixed to the second plate with screws, resulting in a simple structure and easy assembly, thus reducing production costs. Furthermore, the length of the drawer shelf can be adjusted by simply pulling the second plate, making it convenient to use. In summary, this application offers advantages over existing technologies, including a simple structure, easy assembly, low manufacturing costs, and ease of use.

[0010] Preferably, one end of the spiral spring is coiled to form a coiled end, and the other end is a fixed end that is fixed to the first plate or the second plate.

[0016] The fixed end of the spiral spring is fixedly connected to the side wall of the first plate facing the second plate, and the spiral spring is fixedly set on the side close to the first slider; the second slider is provided with a coiling groove that mates with the coiling end.

[0017] Preferably, the first slide groove and / or the second slide groove are provided with two grooves, the first slider is provided with a first protrusion that cooperates with the second slide groove, and the second slider is provided with a second protrusion that cooperates with the first slide groove.

[0035] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0036] Example 1: Refer to Figure 1 As shown, a telescopic drawer partition with a scroll spring 3 includes a first plate 1 and a second plate 2 that can slide relative to each other. The scroll spring 3 is fixedly installed on the first plate 1 and / or the second plate 2, and the first plate 1 and the second plate 2 are relatively fixed to each other by the scroll spring 3.

[0037] One end of the spiral spring 3 is coiled to form a coiled end 31, and the other end is a fixed end 32 that is fixed to the first plate 1 or the second plate 2. The fixed end 32 is used to fix it to the first plate 1 or the second plate 2, which facilitates the installation of the spiral spring 3.

[0038] The first plate 1 has a telescopic hole 12 arranged along its length direction, and the second plate 2 is slidably arranged in the telescopic hole 12; the spiral spring 3 is fixedly arranged in the telescopic hole 12; the end of the second plate 2 is provided with a coiling groove 22 that cooperates with the coiling end 31.

[0039] A through hole is provided on the fixed end 32, and the spiral spring 3 is fixedly mounted on the first plate 1 or the second plate 2 by screws 33. The through hole facilitates the fixing of the spiral spring 3 to the first plate 1 and the second plate 2.

[0040] In one embodiment, a limiting spring piece 521 is provided at the opening of the telescopic hole 12, and a limiting groove 61 that cooperates with the limiting spring piece 521 is provided at the end of the second plate 2 away from the first plate; a limiting stop piece 521 is provided at the end of the limiting spring piece 52 facing the limiting groove.

[0041] A spiral spring (also known as a coiled spring) is a type of spring made of elastic material (such as spring steel sheets, alloy sheets, etc.) wound into a planar spiral or cylindrical spiral structure. Its shape resembles a coiled watch spring, with uniform sheet thickness and tiny gaps between adjacent coils during winding, forming a compact spiral shape. When an external force is applied to tighten the spring (storing elastic potential energy), it returns to its original shape through elastic deformation after being released, releasing energy and generating torque or tension.

[0042] The working principle of this utility model is as follows: In this utility model, a spiral spring 3 is provided on one side of the telescopic hole 12 in the width direction. The coiling end 31 cooperates with the coiling groove 22. When the second plate 2 is pushed into the telescopic hole 12, the coiling groove 22 can drive the coiling end 31 to move, so that the spiral spring 3 is stretched. When the external force is no longer applied to the second plate 2, it can use the elastic restoring force of the spiral spring 3 itself to push the second plate 2 to move outward, so that the length of the entire drawer partition is extended.

[0043] Therefore, in practical use, under the action of the scroll spring 3, the first plate 1 and the second plate 2 in this application are in their longest state. Based on the width of the drawer, the second plate 2 is pushed to overcome the elastic force of the scroll spring 2, causing the second plate 2 to move towards the telescopic hole 12, thereby adjusting the drawer partition to a suitable length. Then, the drawer partition is placed inside the drawer. Under the elastic restoring force of the scroll spring 3, the second plate 2 can be continuously pushed, maintaining a tendency to move outwards from the telescopic hole 3, so that both ends of the drawer partition can stably abut against the inner wall of the drawer, dividing the space inside the drawer.

[0044] Furthermore, since this invention remains in an extended state under the action of the spiral spring 3, to facilitate transportation, the second plate 2 can retract into the telescopic hole 12 during transport. In this embodiment, a limiting spring piece 52 is provided at the opening of the telescopic hole 12, and a limiting groove 61 that cooperates with the limiting spring piece 52 is provided at the end of the second plate 2 away from the first plate 1; a limiting stop piece 521 is provided at the end of the limiting spring piece 52 facing the limiting groove 61. When the second plate 2 retracts into the telescopic hole 12, the limiting stop piece 521 can be locked at the end of the limiting groove 61, so that the second plate 2 is kept within the telescopic hole 12 of the first plate 1, thereby keeping the volume and length to a minimum. In use, it is only necessary to pry the limiting spring piece 52 to disengage the limiting stop piece 521 from the end of the limiting groove 61, and it can be used normally.

[0045] Compared with the prior art, this utility model has a simple structure, mainly comprising a spiral spring 3, a first plate 1, and a second plate 2. During installation, the spiral spring 3 is directly fixed into the telescopic hole 12 of the first plate 1 using screws 33, resulting in a simple structure and easy assembly, thus reducing production costs. Furthermore, the length of the drawer shelf can be adjusted by directly pulling the second plate 2, making it convenient to use. In summary, this application has the advantages of simple structure, convenient assembly, low manufacturing cost, and ease of use compared to the prior art.

[0046] Example 2: Refer to Figures 2 to 4 As shown, a telescopic drawer partition with a scroll spring 3 includes a first plate 1 and a second plate 2 that can slide relative to each other. The scroll spring 3 is fixedly installed on the first plate 1 and / or the second plate 2, and the first plate 1 and the second plate 2 are relatively fixed to each other by the scroll spring 3.

[0047] In this embodiment, one end of the spiral spring 3 is coiled to form a coiled end 31, and the other end is a fixed end 32 that is fixed to the first plate 1 or the second plate 2. The fixed end 32 is used to fix the spiral spring 3 to the first plate 1 or the second plate 2, which facilitates the installation of the spiral spring 3.

[0048] The first plate 1 and the second plate 2 are arranged in parallel; the first plate 1 and the second plate 2 are bonded to each other in the thickness direction;

[0049] A first groove 11 is provided on the side wall of the first plate 1 facing the second plate 2, which is arranged along its length direction, and a first slider 4 is fixedly provided at one end of the first plate 1.

[0050] The side wall of the second plate 2 is provided with a second slide groove 21 arranged along its length direction, and the first slider 4 cooperates with the second slide groove 21; the end of the second plate 2 away from the first slider 4 is provided with a second slider 5, and the second slider 5 cooperates with the first slide groove 11.

[0051] The fixed end 32 of the spiral spring 3 is fixedly connected to the side wall of the first plate 1 facing the second plate 2, and the spiral spring 3 is fixedly disposed on the side close to the first slider 4; the second slider 5 is provided with a coiling groove 22 that cooperates with the coiling end 51.

[0052] In this embodiment, when the first plate 1 and the second plate 2 slide, a first slider 4 that cooperates with the second plate 2 is provided on the first plate 1, and a second slider 5 that cooperates with the first plate 1 is provided on the second plate 2, so that the first plate 1 and the second plate 2 can slide more stably relative to each other.

[0053] In addition, as in this embodiment, the first slide groove 11 and / or the second slide groove 21 are provided with two slides, the first slider 4 is provided with a first protrusion 41 that cooperates with the second slide groove 21, and the second slider 5 is provided with a second protrusion 51 that cooperates with the first slide groove 11. The cooperation of the two slide grooves and the two sliders makes the sliding between the first plate 1 and the second plate 2 more stable.

[0054] A through hole is provided on the fixed end 32, and the spiral spring 3 is fixedly mounted on the first plate 1 by a screw 33. The through hole facilitates the fixing of the spiral spring 3 to the first plate 1 and the second plate 2. In this embodiment, the screw 33 passes through the through hole and is fixedly connected to the first plate 1.

[0055] A spiral spring (also known as a coiled spring) is a type of spring made of elastic material (such as spring steel sheets, alloy sheets, etc.) wound into a planar spiral or cylindrical spiral structure. Its shape resembles a coiled watch spring, with uniform sheet thickness and tiny gaps between adjacent coils during winding, forming a compact spiral shape. When an external force is applied to tighten the spring (storing elastic potential energy), it returns to its original shape through elastic deformation after being released, releasing energy and generating torque or tension.

[0056] The working principle of this utility model is as follows: A spiral spring 3 is installed on the side wall of the first plate 1 facing the second plate 2. The coiled end 31 cooperates with the coiling groove 22. When it is necessary to shorten the drawer partition, the first plate 1 or the second plate 2 can be pushed, increasing the overlap length between the first plate 1 and the second plate 2, thereby shortening the drawer partition. During the shortening process, the coiling groove 22 can drive the coiled end to move, causing the spiral spring 3 to be stretched. When the external force on the second plate 2 is removed, the spiral spring 3 can utilize its own elastic restoring force to push the second plate 2 and the first plate 1 away from each other, thus extending the length of the entire drawer partition.

[0057] Therefore, in practical use, under the action of the scroll spring 3, the first plate 1 and the second plate 2 in this application are in their longest state for the drawer divider. Then, according to the width of the drawer, the first plate 1 and the second plate 2 are pushed to overcome the elastic force of the scroll spring 2, increasing the overlap length between the first plate 1 and the second plate 2. This adjusts the drawer divider to a suitable length, after which the drawer divider is placed inside the drawer. Under the elastic restoring force of the scroll spring 3, the first plate 1 and the second plate 2 are continuously pushed away from each other, maintaining the tendency of the drawer divider to extend, so that the two ends of the drawer divider can stably abut against the inner wall of the drawer, thus dividing the space inside the drawer.

[0058] Compared with the prior art, this utility model has a simple structure, mainly consisting of a spiral spring 3, a first plate 1, and a second plate 2. During installation, the spiral spring 3 is directly fixed to the first plate 2 using screws 33, resulting in a simple structure and easy assembly, thus reducing production costs. Furthermore, the length of the drawer shelf can be adjusted by directly pulling the second plate 2, making it convenient to use. In summary, this application has the advantages of simple structure, convenient assembly, low manufacturing cost, and ease of use compared to the prior art.

[0059] Example 3: Reference Figures 2 to 4 As shown, this embodiment is similar in structure to that in embodiment 2, except that a limiting end block 6 is provided at the end of the first plate 1 away from the first slider 4, and a limiting groove 61 is provided on the limiting end block 6 along the length direction of the first plate 1.

[0060] The second slider 5 is provided with a limiting spring piece 52 that cooperates with the limiting groove 61. A limiting stop piece 521 is provided at the end of the limiting spring piece 52 facing the limiting groove 61. The limiting spring piece 52 is inclined towards the second plate 2.

[0061] In Embodiment 2, because the present invention is kept in an extended state under the action of the spiral spring 3, in order to facilitate transportation and keep the drawer partition in its shortest state, a limiting spring piece 52 is provided on the second slider 5 in this embodiment, and a limiting groove 61 that cooperates with the limiting spring piece 52 is provided at the end of the first plate 1; a limiting stop piece 521 is provided at the end of the limiting spring piece 52 facing the limiting groove 61. When the first plate 1 and the second plate 2 are completely overlapped, and the drawer partition is at its shortest length, the limiting stop piece can be locked at the end of the limiting groove 61, so that the drawer partition is kept in its shortest length state, thereby keeping the volume of the drawer partition as small as possible and the length as short as possible. In use, it is only necessary to pry the limiting spring piece 52 so that the limiting stop piece 521 is disengaged from the end of the limiting groove 61. Under the action of the elastic restoring force of the spiral spring 3, the first plate 1 and the second plate 2 move away from each other, and the drawer partition is extended and can be used normally.
