Description

Technical Field

[0001] The present invention belongs to the field of daily necessities, and particularly relates to a storage device with adjustable opening size. Background Art

[0002] Currently, when using a storage device in daily life, a flexible bag such as a cloth bag or a plastic bag is often used to cover the inside of the storage device to prevent the items in the storage device from falling. During the use of a storage device, especially a trash can, a garbage bag is usually put inside the trash can. The opening size of the trash can is often fixed and cannot be adjusted. Since the specifications of garbage bags vary, when the existing garbage bag is too small, it cannot cover the edge of the trash can opening, which easily causes the garbage to fall outside the garbage bag, increasing the cleaning work.

[0003] Therefore, a new technology is needed to solve the problem that the opening of the trash can in the prior art cannot be adjusted. Summary of the Invention

[0032] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present invention in combination with the embodiments and the drawings, so as to fully understand the purpose, solution and effects of the present invention. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The same reference signs used everywhere in the drawings indicate the same or similar parts.

[0033] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. In addition, the up, down, left, right, etc. descriptions used in the present invention are only relative to the mutual positional relationship of the components of the present invention in the drawings.

[0034] Refer to Figures 1 to 4 , a storage device with adjustable opening, including a first support member 1, a second support member 2, a base 4 and a telescopic mechanism 3. The first support member 1, the base 4 and the second support member 2 are sequentially hinged end to end to form a tank body 5 with an upward opening. The opening of the tank body 5 is the opening of the storage device. A flexible storage bag can be sleeved in the tank body 5. The flexible storage bag can be a plastic garbage bag, and when storing other items, the flexible storage bag can also be a cloth bag. One end of the telescopic mechanism 3 is connected to the first support member 1, and the other end of the telescopic mechanism 3 is connected to the second support member 2. When the telescopic mechanism 3 expands and contracts, the opening of the tank body 5 becomes larger or smaller, so that the size of the opening of the storage device can be adjusted by adjusting the telescopic mechanism 3, and then different specifications of garbage bag sets can be adapted to be sleeved on the edge of its opening. The hinge method can be realized by drilling holes at the hinge points and fitting rivets.

[0035] Specifically, a collection groove 41 is provided on the base 4. The collection groove 41 is in the shape of a wide-mouth rectangular tray with rounded chamfers at the vertices of its four corners. The mouth of the collection groove 41 faces the direction of the opening, and the mouth of the collection groove 41 is upward. When the flexible storage bag ruptures, the items stored inside can fall onto the base 4, and the setting of the collection groove 41 can collect a certain amount of items, thereby preventing the items that fall onto the base 4 from falling to the ground and soiling the ground, and further avoiding an increase in cleaning work. The hinge points of the first support member 1, the second support member 2 and the base 4 are located on the wall of the collection groove 41. The hinge method can be realized by drilling holes at the hinge points and then fitting rivets.

[0036] Specifically, the telescopic mechanism 3 includes a V-shaped link mechanism 31. The V-shaped link mechanism 31 includes a first link 311 and a second link 312. The lengths of the first link 311 and the second link 312 are equal and can be selected according to the actual situation. The first link 311 and the second link 312 are preferably in the structure of straight rods or thin plates. One end of the first link 311 is hinged to one end of the second link 312. The angle of the V-shaped opening of the V-shaped link mechanism 31, that is, the included angle between the first link 311 and the second link 312, is adjustable. The V-shaped link mechanism 31 is located between the first support member 1 and the second support member 2. The included angle between the first support member 1, the second support member 2 and the base 4 changes with the change of the included angle between the first link 311 and the second link 312, so that the opening size of the trough body 5 can be changed, and then trash bag sets of different specifications can be adapted to be sleeved on the opening edge of the trough body 5. The hinge method can be realized by drilling holes at the hinge points and then fitting rivets.

[0037] In one embodiment, the telescopic mechanism 3 of the storage device with adjustable opening is provided with a V-shaped link mechanism 31. One end of the V-shaped link mechanism 31 is connected to the first support member 1, and the other end is connected to the second support member 2. The structure is simple and convenient for adjusting the opening size of the trough body 5.

[0038] In another embodiment, the telescopic mechanism 3 includes a plurality of sequentially connected V-shaped link mechanisms 31. Adjacent two V-shaped link mechanisms 31 are hinged to each other. The V-shaped link mechanisms 31 at the head and the tail are respectively connected to the first support member 1 and the second support member 2. The setting of multiple V-shaped link mechanisms 31 makes the structure more beautiful, and at the same time, the adjustment range of the opening size of the trough body 5 is larger. The hinge method can be realized by drilling holes at the hinge points and then fitting rivets.

[0039] In another embodiment, the telescopic mechanism 3 includes a V-shaped link mechanism 31 and an inverted V-shaped link mechanism 32 corresponding to the V-shaped link mechanism 31 one by one. One end of the inverted V-shaped link mechanism 32 is hinged to the first link 311, and the hinge node thereof and the first link 311 can be located at any point between the two ends of the first link 311. The other end is hinged to the second link 312, and the hinge node thereof and the second link 312 corresponds to the hinge node on the first link 311, so as to avoid jamming when the V-shaped link mechanism 31 and the inverted V-shaped link mechanism 32 adjust the V-shaped opening size. The inverted V-shaped link mechanism 32 includes a third link 321 and a fourth link 322. One end of the third link 321 is hinged to the fourth link 322. The lengths of the third link 321 and the fourth link 322 are equal and can be selected according to the actual situation. The third link 321 and the fourth link 322 can preferably be straight rods or thin plate-like structures. A structure in which one or more pairs of the V-shaped link mechanism 31 and the inverted V-shaped link mechanism 32 are hinged can be provided. The V-shaped link mechanism 31 and the inverted V-shaped link mechanism 32 jointly adjust the opening size of the trough body 5, the structure is more stable, and at the same time, the structural change of the telescopic mechanism 3 is smoother during the adjustment process. The hinge method can be realized by drilling holes at the hinge points and then fitting rivets.

[0040] In another embodiment, the telescopic mechanism 3 includes a plurality of V-shaped link mechanisms 31 and inverted V-shaped link mechanisms 32 corresponding to the V-shaped link mechanisms 31 one by one. Extension segments 33 are respectively provided at the adjacent two ends of the adjacent two inverted V-shaped link mechanisms 32, and the two extension segments 33 are hinged. The hinge method can be realized by drilling holes at the hinge points and then fitting rivets.

[0041] In another embodiment, the telescopic mechanism 3 includes a plurality of V-shaped link mechanisms 31 and inverted V-shaped link mechanisms 32 corresponding to the V-shaped link mechanisms 31 one by one. Extension segments 33 are respectively provided at the adjacent two ends of the adjacent two inverted V-shaped link mechanisms 32, and the two extension segments 33 are hinged. At least one of the hinge nodes of the two extension segments 33 is located on the base 4, which can improve the stability of the telescopic mechanism 3 and avoid randomly changing the opening size due to being too loose. The hinge method can be realized by drilling holes at the hinge points and then fitting rivets.

[0042] In one embodiment, two of the hinge nodes of the extension segment 33 are located on the base 4 and are connected to the wall of the collection trough 41.

[0043] In this embodiment, one of the hinge nodes of the extension segment 33 is located on the base 4 and is connected to the wall of the collection trough 41.

[0044] Specifically, the first support member 1 and the second support member 2 have the same structure. The first support member 1 includes a plate body 11 and a connecting member 12. The plate body 11 is provided with a first folded edge 111 and a first side plate 112 connected in sequence. The first folded edge 111 is provided with an elongated hole 1111 along the direction towards the base 4. The connecting member 12 can slide along the elongated hole 1111. One end of the telescopic mechanism 3 is hinged to the connecting member 12. The hinging method can be realized by drilling holes at the hinge point and then fitting rivets.

[0045] In this embodiment, the plate body 11 is provided with a first folded edge 111, a first side plate 112 and a second folded edge 113 connected in sequence in the horizontal direction. The first folded edge 111 and the second folded edge 113 are symmetrically provided with elongated holes 1111 along the direction towards the base 4. The two telescopic mechanisms 3 are symmetrically arranged on both sides of the base 4 and are spaced apart from the first support member 1 and the second support member 2.

[0046] Specifically, the plate body 11 further includes a third folded edge 114. The third folded edge 114 is located at one end of the plate body 11 away from the base 4 and is between the first folded edge 111 and the second folded edge 113, so that the edge of the structure of the plate body 11 is a curled edge structure, which avoids damage to the user or the flexible storage bag caused by a straight edge structure and has a beautiful structure.
