Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, and in particular relates to a folding cabinet with a vacuum compression bag. Background Technology

[0002] With the trend towards more compact living spaces, vacuum compression bags are widely used because they significantly reduce the space occupied by bulky items such as clothing and bedding. However, traditional vacuum compression bags often collapse after vacuuming due to a lack of rigid support, leading to clutter and difficulty in categorizing and retrieving items. Furthermore, they still require storage space when not in use. Meanwhile, while existing folding lockers are compressible, their structures often use simple nesting methods, failing to dynamically coordinate with vacuum compression bags. Firstly, conventional folding lockers lack mechanisms to secure the compression bags, easily causing displacement and air leakage. Secondly, traditional support structures cannot deform synchronously during vacuuming, posing a risk of structural interference. Utility Model Content

The first interlayer support includes a first mounting frame and a cover plate. The cover plate includes an air extraction port with a one-way valve. The bag opening is connected to the first mounting frame. The cover plate is adapted to openably and closeably seal the bag opening.

[0007] A folding mechanism is supported between the first interlayer support member and the second interlayer support member. The folding mechanism includes an unfolded state, a folded state, and several folded states between the unfolded state and the folded state.

[0008] A support mechanism is adapted to continuously provide a driving force that causes the folding mechanism to tend to turn into an unfolded state. In its natural state, the support mechanism is adapted to provide a driving force that keeps the folding mechanism in an unfolded state.

[0009] When the vacuum compression bag is evacuated, the cabinet can fold itself, the first interlayer support moves closer to the second interlayer support, and the folding mechanism can change from an unfolded state to a folded state or a stowed state until it is in force equilibrium.

[0010] Preferably, the folding mechanism includes an X-shaped folding unit, and the support mechanism includes a torsion spring pivotally connected to the X-shaped folding unit to provide a driving force that restricts its rotational opening and closing, wherein:

[0011] The X-shaped folding unit includes a pivot shaft and two unit rods that rotate and open / close around the pivot shaft. The torsion spring includes a helical body adapted to store and release angular energy and two torsion arms adapted to transmit torque. The helical body is fitted onto the pivot shaft. The two torsion arms are adapted to extend into the two unit rods respectively. The torsion arms are parallel to the unit rods and are adapted to provide a driving force that restricts the rotation and opening / closing of the unit rods along a direction perpendicular to their length. The two torsion arms have an initial angle, and the torsion arms are adapted to drive the two swing arms to form and maintain an angle between the initial angles, i.e., to keep the folding mechanism in the unfolded state.

[0012] Preferably, the unit rod includes two swing arms extending opposite to each other from the pivot axis. The X-shaped folding unit can be divided into two left-right symmetrical first half-sections. The two swing arms in the first half-sections move away from each other during unfolding.

[0016] The transverse X-shaped folding unit includes two transverse unit rods pivotally connected in an X-shape. Each transverse unit rod includes a transverse sliding column. The first transverse stringer and the second transverse stringer each form a transverse sliding groove. The transverse sliding column can reciprocate within the transverse sliding groove to a limited extent.

[0017] The transverse slide is adapted to limit the unfolding range of the transverse X-shaped folding unit, and the longitudinal slide is adapted to limit the unfolding range of the longitudinal X-shaped folding unit. Specifically, the transverse sliding column moves between the two ends of the transverse slide and the longitudinal sliding column moves between the two ends of the longitudinal slide, so that the folding mechanism can simultaneously switch between the stowed state and the unfolded state.

[0018] The longitudinal X-shaped folding unit includes two longitudinal unit rods pivotally connected in an X-shape. Each longitudinal unit rod includes a longitudinal sliding column. The first longitudinal stringer and the second longitudinal stringer are respectively formed with longitudinal grooves. The longitudinal sliding column can reciprocate within the longitudinal grooves to a limited extent.

[0019] Preferably, the transverse slides located in the same horizontal plane are centrally symmetrical, and the transverse slides located in the same vertical plane are axially symmetrical; the longitudinal slides located in the same horizontal plane are centrally symmetrical, and the longitudinal slides located in the same vertical plane are axially symmetrical.

[0020] Preferably, the first interlayer support member includes a first support column disposed at its corner, and / or the second interlayer support member includes a second support column disposed at its corner, wherein: the first support column abuts against the second interlayer support member to limit a minimum height; or, the second support column abuts against the first interlayer support member to limit a minimum height; or, the first support column and the second support column abut against each other to limit a minimum height; the height of the folding mechanism in the folded state does not exceed the minimum height, avoiding damage to the mechanism caused by excessive folding.

[0021] Preferably, the cover plate can be completely separated from the first mounting frame, or the cover plate is pivotally connected to the first mounting frame, and the cover plate can be flipped to fully expose the bag opening, wherein: a plurality of plate buckles are pivotally connected to the periphery of the cover plate, and the first mounting frame is correspondingly provided with a fastening edge that engages with the plate buckles, and the plate buckles engage with the fastening edge to maintain a sealed fit between the cover plate and the first mounting frame.

[0022] Preferably, the first mounting frame includes an annular step, an annular fitting, and a fixing profile. The annular step includes a first step portion and a second step portion disposed above the first step portion. The first step portion and the annular fitting are adapted to engage and press the bag opening. The first step portion includes a first horizontal annular surface, and the annular fitting includes a slot portion, which is formed by an outer periphery, an inner periphery, and a second horizontal annular surface. The vacuum compression bag includes a bag edge adapted to surround and form the bag opening, and the bag edge can be connected to the second horizontal surface by a heat-pressing process. The first horizontal annular surface and the second horizontal annular surface are clamped on both sides of the bag edge. The fixing profile includes a fixing top plate, a first fixing side plate, and a second fixing side plate. The fixing top plate is adapted to form the upper surface of the first mounting frame and abuts against the cover plate. The first fixing side plate is adapted to press the second step portion, and the second fixing side plate is adapted to extend into the slot portion and press the annular fitting. The fixing profile, the annular step, and the annular fitting are assembled into one piece by a number of screws.

[0023] Preferably, the cover plate is provided with a corresponding sealing groove, and a sealing ring is provided in the sealing groove. The upper end of the inner periphery is adapted to extend into the sealing groove and fit tightly with the sealing ring. Preferably, two adjacent transverse X-shaped folding units are pivotally connected, and two adjacent longitudinal X-shaped folding units are pivotally connected.

[0024] Preferably, the cabinet further includes a flexible protective layer connected between the first interlayer support and the second interlayer support. The flexible protective layer is disposed between the folding mechanism and the vacuum compression bag, which effectively prevents the vacuum compression bag from being torn by sharp objects or damaged in other ways during storage. In particular, it effectively prevents friction damage between the folding mechanism and the bag body, thus extending the service life of the vacuum compression bag.

[0025] The beneficial effects of this utility model are:

[0026] 1. In its natural state, the folding mechanism can be unfolded for normal storage. By installing the bag opening onto the first mounting frame and achieving coordinated deformation of the cabinet structure and bag body through the folding mechanism, the cabinet can fold or unfold synchronously with the volume change of the vacuum compression bag. This allows the folding mechanism to switch to a folded or stored state after vacuuming, greatly reducing the volume of the cabinet. It is especially suitable for places with limited space, such as small apartments and dormitories, providing ample storage space when needed. At the same time, the cabinet can be completely folded when not in use, occupying very little space and significantly improving space utilization.

[0027] 2. By setting vacuum storage bags inside the cabinet to create storage space, the cabinet has a certain structural strength, which can provide three-dimensional support and protection for the vacuum compression bags, prevent the bags from being deformed by pressure, and ensure the regularity of the storage space. Multiple folding cabinets can be stacked to improve space utilization. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0044] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0045] like Figure 1-13The described folding cabinet with vacuum compression bags includes a cabinet body and a vacuum compression bag 4 housed within the cabinet body. The cabinet body includes an interlayer mechanism, a folding mechanism 3, and a support mechanism. The interlayer mechanism includes a first interlayer support 1 and a second interlayer support 2. The folding mechanism 3 is supported between the first interlayer support 1 and the second interlayer support 2. The folding mechanism 3 includes an unfolded state, a folded state, and several folded states between the unfolded and folded states. The support mechanism is adapted to continuously provide a driving force that tends to cause the folding mechanism 3 to turn into the unfolded state. In its natural state, the support mechanism is adapted to provide a driving force that keeps the folding mechanism 3 in the unfolded state. The first interlayer support 1 includes a first mounting frame 11 and a cover plate 12. The second interlayer support 2 includes a second mounting frame 21 and a base plate 22. The base plate 22 is adapted to support the vacuum compression bag. The vacuum compression bag includes an opening for items to enter, which is connected to a first mounting frame 11. A cover 12 is adapted to openably seal the opening. The cover 12 includes an air extraction port 121 with a one-way valve. The one-way valve ensures that air cannot flow back after vacuuming, maintaining the stability of the vacuum state. When the vacuum compression bag 4 is evacuated, the cabinet can fold itself, the first interlayer support 1 approaches the second interlayer support 2, and the folding mechanism 3 can change from an unfolded state to a folded state or a stowed state until it is in equilibrium.

[0046] In this embodiment, the first mounting frame 11 is rectangular and includes a set of first transverse stringers 111 and a set of first longitudinal stringers 112. The second mounting frame 21 is rectangular and includes a set of second transverse stringers 211 and a set of second longitudinal stringers 212. The X-shaped folding unit includes a transverse X-shaped folding unit 31 and a longitudinal X-shaped folding unit 32. The transverse X-shaped folding unit 31 includes two transverse unit rods 311 pivotally connected in an X-shape, and the longitudinal X-shaped folding unit 32 includes two longitudinal unit rods 321 pivotally connected in an X-shape. Two sets of transverse X-shaped folding units 31 are supported between the first transverse stringers 111 and the second transverse stringers 211, and adjacent transverse X-shaped folding units 31 are pivotally connected. One transverse unit rod 311 is slidably engaged with the first transverse stringer 111 in a direction perpendicular to the telescopic direction, and the other transverse unit rod 311 is hinged to the first transverse stringer 111. One transverse unit rod 311 slides with the second transverse stringer 211 perpendicular to the telescopic direction, and another transverse unit rod 311 is hinged to the second transverse stringer 211. Three sets of longitudinal X-shaped folding units 32 are supported between the first longitudinal stringer 112 and the second longitudinal stringer 212. Adjacent longitudinal X-shaped folding units 32 are pivotally connected. One longitudinal unit rod 321 slides with the first longitudinal stringer 112 perpendicular to the telescopic direction, and another longitudinal unit rod 321 is hinged to the first longitudinal stringer 112. One longitudinal unit rod 321 slides with the second longitudinal stringer 212 perpendicular to the telescopic direction, and another longitudinal unit rod 321 is hinged to the second longitudinal stringer 212. In the folded state, the transverse unit rods 311 and 321 are horizontally positioned, with the horizontal and vertical horizontal rods perpendicular to each other; in the unfolded state, the transverse unit rods 311 and 321 are rotated 30° from their horizontal positions.

[0047] In this embodiment, the transverse unit rod 311 includes a first pivot shaft 3111 and transverse swing arms 3112 extending opposite to the first pivot shaft 3111. The two transverse swing arms 3112 are parallel but not collinear. The transverse X-shaped folding unit 31 can be divided into two left-right symmetrical first half-sections. The two transverse swing arms 3112 in the first half-section move away from each other during unfolding. The transverse X-shaped folding unit 31 can also be divided into two left-right symmetrical second half-sections. The two transverse swing arms 3112 in the second half-section move closer to each other during unfolding. The support structure includes a torsion spring 312, which is pivotally connected to the X-shaped folding unit to provide a driving force that restricts its rotational opening and closing. The torsion spring 312 includes a helical body 3121 adapted to store and release angular energy and two torsion arms 3122 adapted to transmit torque. The two torsion arms 3122 have an initial angle. The two transverse swing arms 3112 disposed in one of the second half-sections have an initial obtuse angle. The torsion arm 3122 is adapted to maintain the initial angle between the two transverse swing arms 3112, i.e., to keep them in the unfolded state. The torsion spring drives the X-shaped unit rod to maintain the unfolded state through preset angular energy, supporting the cabinet structure without manual adjustment. The longitudinal unit rod 321 includes a second pivot axis and a longitudinal swing arm extending from the second pivot axis in opposite directions. The two longitudinal swing arms are parallel but not collinear. It is understood that the transverse unit rod and the longitudinal unit rod differ only in size, and the torsion spring 312 can be set in the longitudinal X-shaped folding unit in the same way. The above design ensures structural stability during use, avoids the extension and retraction of the folding mechanism 3 due to the handling of items, and improves the user experience. During vacuuming, the torsion spring 312 can also elastically offset the instantaneous pressure of the bag shrinking on the cabinet, avoiding deformation caused by direct impact on the rigid structure. When the vacuum is released, the elastic restoring force of the torsion spring assists the cabinet to quickly unfold to the unfolded state.

[0048] In this embodiment, the first transverse stringer 111 includes a transverse groove 314, the second transverse stringer includes a transverse groove 314, and the transverse unit rod 311 includes a transverse sliding column 313, which can reciprocate within the transverse groove 314 to a limited extent. The first longitudinal stringer 112 includes a longitudinal groove 324, the second longitudinal stringer includes a longitudinal groove 324, and the longitudinal unit rod 321 includes a longitudinal sliding column 323, which can reciprocate within the longitudinal groove 324 to a limited extent. The transverse groove 314 is suitable for defining the unfolding range of the transverse X-shaped folding unit 31, and the longitudinal groove 324 is suitable for defining the unfolding range of the longitudinal X-shaped folding unit 32. Specifically, the transverse sliding column 313 moves between the two ends of the transverse groove 314, and the longitudinal sliding column 323 moves between the two ends of the longitudinal groove 324, so that the folding mechanism 3 can simultaneously switch between the folded state and the unfolded state. The endpoints of the horizontal slide 314 and / or the vertical slide 324 serve as hard stops to ensure that the cabinet is structurally locked in the unfolded or retracted state, preventing overshoot or rebound.

[0049] In this embodiment, the transverse slide 314 located in the same horizontal plane is centrally symmetrical, and the transverse slide 314 located in the same vertical plane is axially symmetrical; the longitudinal slide 324 located in the same horizontal plane is centrally symmetrical, and the longitudinal slide 324 located in the same vertical plane is axially symmetrical.

[0050] In this embodiment, the first interlayer support 1 includes a first support column 13 disposed at its corner, and the second interlayer support 2 includes a second support column 23 disposed at its corner. The first support column 13 and the second support column 23 abut against each other to limit the minimum height. The height of the folding mechanism in the folded state does not exceed the minimum height. The folding mechanism 3, together with the first support column 13 and / or the second support column 23, forms the side surface of the cabinet, avoiding damage to the mechanism caused by excessive folding, and avoiding damage to the internal items caused by excessive compression of the vacuum bag.

[0051] In this embodiment, the first mounting frame 11 includes an annular step 113, an annular mating member 114, and a fixing profile 116. The annular step 113 includes a first step portion and a second step portion disposed above the first step portion. The first step portion and the annular mating member 114 are adapted to engage and compress the bag opening. The first step portion includes a first horizontal annular surface 1131, and the annular mating member 114 includes a slot portion 1144, which is composed of an outer periphery 1142, an inner periphery 1141, and a second horizontal annular surface 1143. The vacuum compression bag 4 includes a bag edge 42 adapted to surround and form a bag opening 41. The bag edge 42 can be connected to the second horizontal surface 1143 by a hot-pressing process. The first horizontal annular surface 1131 and the second horizontal annular surface 1143 are clamped on both sides of the bag edge 42. The fixing profile 116 includes a fixing top plate 1161, a first fixing side plate 1162, and a second fixing side plate 1163. The fixing top plate 1161 is adapted to form the upper surface of the first mounting frame 11, and the fixing top plate 1161 abuts against the cover plate 12. The first fixing side plate 1162 is adapted to press against the second step portion, and the second fixing side plate 1163 is adapted to extend into the slot portion 1144 and press against the annular fitting 114. The fixing profile 116, the annular step 113, and the annular fitting 114 are assembled into one piece by a number of screws. The annular fitting 114 disperses the concentrated stress of the vacuum negative pressure on the bag opening 41, preventing the bag opening from cracking after long-term use.

[0052] In this embodiment, the cover plate 12 can be completely separated from the first mounting frame 11. A sealing groove 123 is correspondingly provided on the cover plate 12, and a sealing ring is disposed within the sealing groove 123. The upper end of the inner periphery 1141 is adapted to extend into the sealing groove 123 and tightly engage with the sealing ring. The periphery of the cover plate 12 is pivotally connected by several buckles 122. The first mounting frame 11 is correspondingly provided with a snap-fit ​​edge 115 that engages with the upper buckle 122. The buckle 122 includes a snap-fit ​​portion 1221, which engages with the snap-fit ​​edge 115 to maintain a tight fit between the inner periphery 1141 and the sealing ring. The cover plate 12 is easy to open and close while maintaining a uniform distribution of sealing pressure. The snap-fit ​​structure of the cover plate 12 allows for a certain degree of elastic deformation to adapt to dimensional changes caused by the shrinkage of the bag opening during vacuuming.

[0053] In some other embodiments, the cabinet also includes a flexible protective layer connected between the first interlayer support 1 and the second interlayer support 2. The flexible protective layer is disposed between the folding mechanism 3 and the vacuum compression bag, which effectively prevents the vacuum compression bag from being torn by sharp objects or other damage during storage, and in particular, effectively prevents friction damage between the folding mechanism 3 and the bag body, thus extending the service life of the vacuum compression bag.

[0054] The method of using this folding cabinet with vacuum compression bags is as follows:

[0055] Packing items involves the following steps:

[0056] Step 1: In its natural state, the folding mechanism 3 is in the unfolded state. Remove the cover plate 12 from the mounting frame to expose the bag opening.

[0057] Step 2: Place the items into a vacuum compression bag through the bag opening;

[0058] Step 3: Reinstall the cover plate 12 back into the mounting frame to seal the bag opening. Use the vacuum pump to vacuum the vacuum compression bag through the vacuum port 121. The folding mechanism 3 folds as the vacuum compression bag contracts. The first interlayer support 1 approaches the second interlayer support 2. The folding mechanism 3 can be converted from an unfolded state to a folded state or a stowed state until it is in equilibrium.

[0059] Taking out the items involves the following steps:

[0060] Step 1: Remove the cover plate 12 from the mounting frame to expose the bag opening. The folding mechanism 3 unfolds as the vacuum compression bag expands until it is fully returned to the unfolded state.

[0061] Step 2: Remove the items from the vacuum compression bag through the opening;

[0062] Step 3: Reinstall the cover plate 12 back into the mounting frame to seal the bag opening. Use the vacuum pump to vacuum the vacuum compression bag through the vacuum port 121. The folding mechanism 3 folds as the vacuum compression bag contracts until it is in equilibrium.

[0063] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
