DETAILED DESCRIPTION

[0025] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the process of implementing the present application, the inventors found that garbage bags are widely used for collecting garbage and are usually used with traditional garbage cans. However, the traditional garbage cans generally occupy a lot of space and are often placed in some relatively fixed positions. Even in a large area, the number of garbage cans is not large enough to match each person. This arrangement not only causes inconvenience to people who need to work at the desk for a long time, such as office workers, students, and teachers, who cannot clean the waste materials, paper scraps, and food residues (such as coffee cup covers in an office environment and draft paper scraps in a learning environment) in time, but also makes it difficult to store the table garbage (such as hard kitchen waste, such as shrimp and crab shells, and beef and mutton bones) generated during temporary meals. It also makes restaurant customers face the embarrassment of bone shell accumulation and soup leakage while waiting and eating, and makes the garbage mixing problem between the kitchen counter and the dining table in the family dining scene more prominent.

[0027] In view of the above problems, a garbage bag storage folding frame is provided in an embodiment of the present application, as shown in FIG. 1, which comprises: Figures 1-7

[0028] Four base frames 10 connected end to end, adjacent two base frames 10 are rotatably connected, the lengths of the opposite two base frames 10 are equal, a strip-shaped clamping groove 103 is formed on the base frame 10, and the edge of the opening side of the garbage bag can be clamped into the strip-shaped clamping groove 103.​

[0029] In actual implementation, the device can be installed on one side of a table. When replacing a garbage bag, the edge of one side of the bag opening is pulled up and inserted into the strip-shaped clamping groove 103 and clamped tightly. The four edges of the garbage bag are clamped tightly on the corresponding four base frames 10. The garbage bag storage and folding frame is expanded outward to open the bag opening to a certain angle, facilitating normal use. Small garbage such as discarded materials, paper scraps, and food residues can be thrown into the garbage bag through the bag opening, maintaining the cleanliness of the table. The opening degree of the garbage bag opening can be adjusted by the opening degree of the four base frames 10. Figures 1-3 If there is wet garbage emitting a foul odor in the bag, the four base frames 10 can be retracted inward until the garbage bag opening is completely closed. Figures 2-3 This can isolate the odor of the garbage and further reduce the volume of the garbage bag and the garbage bag storage and folding frame, achieving both aesthetics and practicality.

[0030] The garbage bag folding and storage frame provided by the application can solve multi-dimensional pain points through scenario-based design. For high-frequency desk workers, it can achieve instant storage of discarded files and partition management of food waste (such as separate storage of coffee grounds and fruit pits). For restaurant scenarios, a waterproof and leak-proof material garbage bag can quickly store hard garbage such as shrimp and crab shells, chicken and duck bones, etc. with soup, and can be hung to free up the dining table space. The double garbage bag design (one garbage bag is clamped and one garbage bag is sleeved) improves the turnover efficiency. In the home scenario, it can be used as a temporary kitchen residue collection bag (storing discarded vegetable leaves and bone fragments) or a table-specific garbage bag (simultaneously storing napkins and fish bones), avoiding the mixing of dry and wet garbage and the generation of odors. Especially for the storage of hard kitchen waste containing bones and shells, the thickened material can resist puncture by sharp objects, and the handle design allows garbage to be transferred without falling to the ground, keeping the table surface of the office and learning environment, the dining area of the restaurant table, and the cooking table of the home kitchen clean and effectively reducing bacterial growth and cleaning costs.

[0031] As a preferred solution, as shown in Figure 4 , Figure 5 The base frame 10 includes a top plate 101 and a side plate 102 connected together. The side plate 102 is located inside the base frame 10 and is perpendicular to the top plate 101. Adjacent two top plates 101 are rotatably connected. The top plate 101 and the side plate 102 are both provided with a strip-shaped clamping groove 103.

[0032] In particular implementation, the side plate 102 arranged perpendicularly to the top plate 101 can form a vertical angle with the top plate 101, which can be closely fitted with the edge of the table top. In daily use, the base frame on one side can be closely fitted with the edge of the table top, so that when the garbage bag is completely closed, the garbage bag storage folding frame is flush with the edge of the table top, and the volume of the garbage bag and the garbage bag storage folding frame is further reduced. Only the strip-shaped clamping groove 103 of the top plate 101 alone is difficult to completely clamp the edge of the bag opening of the garbage bag. If there is heavy garbage in the garbage bag, the garbage bag may fall off. The strip-shaped clamping groove 103 is also arranged on the side plate 102, and the edge of the bag opening of the garbage bag is sequentially passed through the two strip-shaped clamping grooves 103. Through the two clamping modes, the clamping reliability is enhanced, and the load-bearing capacity of the garbage bag is enhanced.

[0033] As a preferred solution, two adjacent base frames 10 are arranged as a group, and the remaining two adjacent base frames 10 are arranged as another group. The two base frames 10 in the same group and adjacent to each other are rotatably connected. The two base frames 10 in different groups and adjacent to each other are connected by a connecting rod 20. The two ends of the connecting rod 20 are rotatably connected to the two base frames 10 in different groups and adjacent to each other.

[0034] In particular implementation, since the base frame 10 has a certain width, only the four base frames 10 connected at the head and tail are difficult to completely close the bag opening of the garbage bag when the garbage bag storage folding frame is closed. The connecting rod 20 is arranged between the two groups of base frames 10. When the entire garbage bag storage folding frame is inwards retracted to be closed ( Figure 3 ), the two base frames 10 in the same group and adjacent to each other are flush, and the two groups of base frames 10 are respectively located on two non-intersecting parallel lines. The connecting rod 20 connects the end points on both sides of the two parallel lines, and reconstitutes a complete parallelogram, greatly reducing the gap between the two groups of base frames 10 when closed.

[0035] As a supplement to the above preferred solution, the length of the connecting rod 20 is equal to the width of the two base frames 10. In this way, when the garbage bag storage folding frame is closed, the gap between the two groups of base frames 10 is basically zero, and the bag opening of the garbage bag can be completely closed, greatly increasing the sealing performance of the garbage bag when closed.

[0036] As a preferred solution, the strip-shaped clamping grooves 103 of the top plate 101 and the side plate 102 are respectively arranged transversely in the middle of the top plate 101 and the side plate 102. The design in the middle can make the four edges of the entire garbage bag bear force evenly and increase its stability.

[0037] As a preferred solution, as shown in Figure 4As shown, the end of the top plate 101 and the side plate 102 of the strip-shaped clamping groove 103 is provided with an outward opening 104, and the two openings 104 are respectively located at the opposite ends of the strip-shaped clamping groove 103, and the entire strip-shaped clamping groove 103 is in the shape of "L".

[0038] In the specific implementation, the edge of the bag opening is pulled up and inserted into the opening 104 at the end of the strip-shaped clamping groove 103, and then pushed along the opening 104 to the direction of the strip-shaped clamping groove 103. The pulled-up edge of the bag opening is in contact with the bottom of the strip-shaped clamping groove 103, the pulled-up edge of the bag opening is compressed and pulled in the strip-shaped clamping groove 103 to the opposite end of the opening 104, and the sequence is like writing a capital "L". The pulled-up edge of the bag opening is pulled to the middle of the strip-shaped clamping groove 103 and stopped, and then the pulled-up edge of the bag opening is inserted into the opening 104 at the end of the other strip-shaped clamping groove 103, and the sequence is like writing a reversed "L". The pulled-up edge of the bag opening is pulled to the middle of the other strip-shaped clamping groove 103 and stopped, and thus the clamping of the edge of the bag opening on the base frame 10 is completed. The remaining three edges of the bag opening are clamped on the remaining three base frames 10 in the above-mentioned steps, and the clamping of the entire edge of the bag opening is completed. Two openings 104 are provided in the opposite directions of the strip-shaped clamping groove 103, and when the clamped edge of the bag opening in one strip-shaped clamping groove 103 slides to the opening 104 of the strip-shaped clamping groove 103, the clamped edge of the bag opening in the other strip-shaped clamping groove 103 is still in the safe clamping position in the deep part of the strip-shaped clamping groove 103, and the edge of the bag opening in this direction will not fall off due to the sliding of the clamped edge of the bag opening in one strip-shaped clamping groove 103. The falling of the bag opening in this direction is avoided, and the clamping of the bag opening on the base frame 10 is greatly improved, and the sliding phenomenon is also avoided.

[0039] As another preferred solution, as shown in FIG. 2, Figure 5 As shown, the middle part of the top plate 101 and the side plate 102 of the strip-shaped clamping groove 103 is provided with an outward opening 104, and the entire strip-shaped clamping groove 103 is in the shape of "T".

[0040] In specific implementation, the edge of the opening of the garbage bag is pulled up and inserted from the opening 104 in the middle of the two strip-shaped clamping grooves 103, and the edges of the opening of the garbage bag on both sides are pushed simultaneously along the two openings 104 to the direction of the two strip-shaped clamping grooves 103, and the edges of the opening of the garbage bag on both sides are in contact with the bottom of the strip-shaped clamping groove 103 on the same side at the same time, and the edges of the opening of the garbage bag on both sides are pulled simultaneously to the depth of the two strip-shaped clamping grooves 103, and the clamping of the edges of the opening of the garbage bag on one base 10 is completed. The edges of the opening of the garbage bag on the remaining three bases 10 are clamped in the corresponding three directions, and the clamping of the edges of the opening of the garbage bag is completed. The two openings 104 arranged in the middle of the strip-shaped clamping groove can greatly speed up the clamping operation of the edges of the opening of the garbage bag, making the replacement of the garbage bag more convenient, and is very suitable for occasions that require frequent replacement of the garbage bag.

[0041] As a supplement to the above two strip-shaped clamping groove 103 implementation solutions, the width of the opening 104 is wider than the width of the strip-shaped clamping groove 103, so that the edges of the opening of the garbage bag can be more smoothly clamped into the narrower strip-shaped clamping groove 103 from the wider opening 104, making the clamping operation of the garbage bag more convenient.

[0042] As a preferred solution, the two bases 10 in one group are hinged by a bolt 501 and installed on the edge of the desktop 50.

[0043] In specific implementation, as shown in Figure 6 , the installation method of the garbage bag storage and folding frame is suitable for scenarios where the desktop is relatively thin, and when the garbage bag storage and folding frame is completely closed, the bases 10 in one group on the adjacent desktop are flush with the desktop.

[0044] As a preferred solution, the garbage bag storage and folding frame further includes a fixed frame 40, one side of the fixed frame 40 is fixedly arranged on the side of the table body, and a fixed bolt 401 vertically arranged on the frame body extending outward from the table body is installed on the fixed frame 40. The two bases in one group are hinged by the fixed bolt 401 and installed on the fixed frame 40, and the fixed nut 402 is threadedly connected to the fixed bolt 401.

[0045] In specific implementation, when the desktop is relatively thick, the garbage bag storage and folding frame can be installed on the side of the table body, as shown in Figure 7 , the two bases in one group are hinged by the fixed bolt 401 and installed on the fixed frame 40, and the garbage bag storage and folding frame is installed on the side of the table body through the fixed frame 40 by tightening the fixed nut 402.

[0046] As a preferred solution, two adjacent base frames 10 in the same group are hinged by the carabiner 30, and the two ends of the connecting rod 20 are hinged to two adjacent base frames 10 in different groups by the carabiner 30.

[0047] As a preferred solution, at least one side plate 102 of the base frame 10 is provided with a magnetic strip, and when the garbage bag storage and folding frame is closed, the two adjacent side plates 102 are attracted to each other by magnetic force until they are tightly attached. With the help of magnetic force, the closing of the garbage bag storage and folding frame (or the closing of the garbage bag) is more labor-saving. At the same time, the setting of the magnetic strip can maintain the closed state of the garbage bag for a long time.

[0048] The garbage bag storage and folding frame provided by the present application adopts four base frames connected end to end, and realizes the switching between the closed state and the unfolded state of the folding frame through the rotation and push-pull between the base frames. The opening and closing degree of the storage opening can be freely adjusted, which facilitates the smooth passage of garbage of different sizes into the garbage bag through the storage opening. Through the setting of multiple strip-shaped clamping grooves, the bag opening edge of the garbage bag is clamped on the rack in a clamped manner through two clamping sections, which strengthens the clamping firmness and enhances the load-bearing capacity of the garbage bag. Through the setting of the connecting rod, the gap between the two groups of base frames when closed is greatly reduced, and the sealing performance of the garbage bag when closed is increased. The setting of the L-shaped strip-shaped clamping groove effectively avoids the slipping phenomenon of the garbage bag, which is equivalent to adding an additional layer of insurance. The setting of the T-shaped strip-shaped clamping groove makes the replacement of the garbage bag more convenient, which is beneficial to the occasions where the garbage bag needs to be replaced frequently. The garbage bag storage and folding frame provided by the present application can select the corresponding installation mode according to different occasions, has a wide range of applications, and has the advantages of small overall size, simple structure, low cost, convenient operation, and strong practicability. It can effectively solve the problem of the placement of garbage bags in places where the ground resources are scarce, and has strong practicability.
