Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to a bag, a bag fixing device and a bag mounting structure. Background Art

[0002] Bags are often used to package or hold items. Bags are used in many scenarios, and a common bag scenario is to use them as garbage bags. In order to facilitate the production and transportation of bags, bags are usually connected end to end, that is, the bottom of one bag is connected to the opening of another bag, so that the bags are connected in sequence in a belt shape. The belt-shaped bags usually need to be rolled up for storage, that is, to form a bag roll. When using, pull out the bag roll, tear off one of the bags, and then use the bag to hold items or garbage.

[0003] Traditional bag rolls usually require users to manually pull them out and tear them apart. Since the bags are tightly together before opening, it is difficult to separate them using machines or robots. Therefore, traditional bags are difficult to use on automatic or intelligently controlled machines. For example, if you want to achieve automatic opening of the bag on a trash can, it will be difficult to achieve using the traditional bag structure. Summary of the invention

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0038] like Figure 1 and Figure 2 As shown, it is a bag 10 in an embodiment, including a bag body 100, one end of the bag body 100 is a bag opening end 110, and the other end of the bag body 100 is a bottom end 120. The bag opening end 110 opens a bag opening 101, and the bag opening 101 has a first side wall 130 and a second side wall 140 that are oppositely arranged, one side of the first side wall 130 is connected to one side of the second side wall 140, and the other side of the first side wall 130 is connected to the other side of the second side wall 140, and at least one string hole 102 is opened on the first side wall 130, and the second side wall 140 and the string hole 102 are staggered with each other.

[0039] In this embodiment, the bottom end 120 of the bag body 100 is closed, and the bag opening end 110 is provided with a bag opening 101, so that articles can enter the bag body 100 through the bag opening 101. The first side wall 130 and the second side wall 140 of the bag body 100 are connected to form the bag opening 101. The side wall on one side of the bag opening 101 is the first side wall 130, and the side wall on the other side of the bag opening 101 is the second side wall 140. When the bag body 100 is folded, the first side wall 130 abuts against the second side wall 140, so that the bag opening 101 is closed. The string holes 102 provided on the first side wall 130 are used to enable the bag body 100 to be strung on the fixed column. When multiple bag bodies 100 are aligned and stacked in sequence, the string holes 102 are aligned in sequence, and the fixed column is used to pass through each string hole 102 in sequence, so that multiple bag bodies 100 can be stacked and fixed on the fixed column. When the bag bodies 100 are stacked, each bag body 100 is folded and the first side wall 130 of the bag opening 101 is in contact with the second side wall 140. Since the second side wall 140 does not have a string hole 102, the first side walls 130 of the bag openings 101 of the multiple bag bodies 100 will be connected to the fixed column, while the second side walls 140 of the bag openings 101 of the bag bodies 100 will not be fixed to the fixed column. When the second side wall 140 is subjected to a force in a direction away from the first side wall 130, the second side wall 140 will be separated from the first side wall 130, so that the bag opening 101 is opened.

[0040] It is worth mentioning that the bag in the present application can be used as a garbage bag. In this way, when multiple garbage bags are strung on a fixed column through the string hole 102, multiple bag bodies 100 are stacked in sequence, making the bag body 100 easy to store and transport, which is different from the storage structure of the traditional rolled garbage bag. When it is necessary to separate a single garbage bag, the garbage bag is torn off from the fixed column in sequence, without the need to tear the garbage bag roll apart in the traditional way. In addition, the first garbage bag at the front of the stack can be easily opened without affecting other garbage bags at the back, which is more convenient to use than the traditional rolled garbage bag, and is also suitable for a garbage can with the function of automatically opening the bag, so that the garbage bag can be automatically opened in the garbage can, which will be further explained in the following embodiments.

[0041] It should be connected that the second side wall 140 of the bag opening 101 is staggered with the string hole 102 of the first side wall 130, which means that the second side wall 140 is not aligned with the string hole 102, and the second side wall 140 does not block the string hole 102, so that when the fixing column passes through the string hole 102, the second side wall 140 will not block the passage of the fixing column. The mutual staggering of the second side wall 140 and the string hole 102 can be achieved through a variety of structures, such as setting the width of the first side wall 130 and the second side wall 140 to be different, so that the second side wall 140 and the string hole 102 are staggered, or setting the height of the first side wall 130 and the second side wall 140 to be different, so that the second side wall 140 and the string hole 102 are staggered.

[0042] In one embodiment, the two sides of the first side wall 130 are folded to form two first folded portions 131, and the two first folded portions 131 are respectively provided with the string holes 102. In this embodiment, the two sides of the first side wall 130 are folded inward, and the first folded portions 131 are respectively formed on the two sides of the first side wall 130, each first folded portion 131 is provided with a string hole 102, and the center line of the two string holes 102 is parallel to the edge of the bag opening 101, that is, the two string holes 102 are flush, and the first folded portions 131 are provided to make the bag body 100 easy to fold, and multiple bag bodies 100 can be conveniently stacked and placed. In addition, since the two first folded portions 131 are provided on the two sides of the first side wall 130, the string holes 102 are located on the two sides of the first side wall 130, so that the string holes 102 can avoid the second side wall 140. For example, the width of the second side wall 140 is smaller than the width of the first side wall 130 after folding, and the two string holes 102 are respectively located on the outside of the two sides of the second side wall 140, so that the second side wall 140 and the string holes 102 can be staggered to avoid the second side wall 140 blocking the string holes 102. Since two points determine a straight line, the bag body 100 can be stably fixed on the fixing column and maintain balance through the fixation of the two string holes 102.

[0043] In one embodiment, the two sides of the second side wall 140 are folded to form two second folded portions 141, and the second folded portions 141 are staggered with the string holes 102. In this embodiment, the two sides of the second side wall 140 are folded inward, and the second folded portions 141 are formed on the two sides of the second side wall 140, and each second folded portion 141 is staggered with the string holes 102 on the first folded portion 131 on the same side. In this way, the two second folded portions 141 can further facilitate the folding of the bag body 100 and facilitate the stacking of multiple bag bodies 100.

[0044] In one embodiment, the width of the first side wall 130 after folding is greater than the width of the second side wall 140 after folding. In one embodiment, the distance between the ends of the two first folded portions 131 is greater than the distance between the ends of the two second folded portions 141, that is, the distance between the ends of the two first folded portions 131 is greater than the distance between the ends of the two second folded portions 141, thereby making the width of the folded first side wall 130 greater than the width of the folded second side wall 140.

[0045] In this embodiment, the width of the first side wall 130 is relatively large and is larger than the width of the bag outlet of the bagging mechanism, and the width of the second side wall 140 is smaller than the width of the bag outlet. In this way, when the first side wall 130 is abutted and blocked by the bagging mechanism of the bag fixing device, the second side wall 140 can pass through the bag outlet. The structure of this embodiment will be further explained in conjunction with the bag fixing device in the following embodiments.

[0046] In order to prevent the second folding portion 141 from blocking the string hole 102, in one embodiment, the distance between the string holes 102 of the two first folding portions 131 is greater than the width of the second side wall 140 after folding, and the two string holes 102 are respectively located on the outside of the two sides of the second side wall 140. In this embodiment, since the width of the folded first side wall 130 is greater than the second side wall 140, the first folding portions 131 on both sides at least partially protrude to the outside of the first side wall 130, and the string holes 102 are opened on the portion of the first folding portion 131 protruding to the outside of the first side wall 130, so that the minimum distance between the string holes 102 on both sides is greater than the width of the second side wall 140 after folding. In this way, the two string holes 102 are respectively located on the outside of the second folding portions 141 on both sides of the second side wall 140, so that the second side wall 140 and the string holes 102 can be staggered to prevent the second side wall 140 from blocking the string holes 102.

[0047] In order to avoid the second side wall blocking the string hole, in one embodiment, the second folded portion is bent so that the second folded portion is staggered with the string hole. In this embodiment, the width of the second side wall and the width of the first side wall can be equal or unequal. When the width of the second side wall is greater than or equal to the distance between the two string holes, in order to avoid blocking the string hole, the second folded portion is bent, and the bending direction can be toward the first folded portion or away from the first folded portion. In this way, the second folded portion is staggered with the string hole, thereby avoiding blocking the string hole.

[0048] In order to avoid the second side wall blocking the string hole, in one embodiment, the height of the first side wall is greater than the height of the second side wall, and the height of the string hole is greater than the height of the second side wall in the portion of the string hole on the first side wall protruding from the second side wall. In this embodiment, the height of the first side wall and the height of the second side wall refer to the distance between the end of the first side wall, the end of the second side wall and the bottom of the bag body with the bottom end of the bag body as a reference. In this embodiment, the side walls on both sides of the bag opening are not flush, and the first side wall of the bag opening protrudes from the bag opening in a direction away from the bottom end. In this way, the height of the string hole opened on the first side wall can be set to be higher than the second side wall. In this way, due to the lower height of the second side wall, the string hole cannot be blocked, thereby avoiding blocking of the string hole. When the first side wall is strung on the fixed column through the string hole, the second side wall can be not fixed on the fixed column, and when subjected to force, it can be away from the first side wall, so that the bag opening is opened.

[0049] In one embodiment, the material of the bag body 100 is plastic. In this embodiment, the bag is a plastic bag, which is easy to fold and produce. In addition, the bag body 100 made of plastic material can be adhered by the nano tape, so that when a movable nano tape is set in the trash can, the second side wall 140 of the bag mouth 101 can be adhered, and move in a direction away from the first side wall 130, so that the second side wall 140 is away from the first side wall 130, and then the bag mouth 101 of the bag body 100 is opened. In addition, the bag body 100 made of plastic can be easy to tear open and easy to tear off from the fixed column, so that the bag body 100 can be easily removed from the fixed column. In other embodiments, the material of the bag body 100 is paper. It is more environmentally friendly to make bags with paper, and it is easy to tear off from the fixed column.

[0050] In one embodiment, Figures 3 to 5As shown, a bag fixing device 20 is provided, including: a bagging mechanism 200, a propulsion mechanism 210 and a support member 220; the bagging mechanism 200 is provided with a fixing column 231, the bagging mechanism 200 is provided with a bag outlet 232, the support member 220 is connected to the bagging mechanism 200, one end of the propulsion mechanism 210 is connected to the support member 220, and the other end of the propulsion mechanism 210 is movably abutted against the bagging mechanism 200.

[0051] In this embodiment, the bag fixing device 20 can be used independently to store bags, which is convenient for users to take bags. In addition, the bag fixing device 20 can also be used in a trash can 30. The bag fixing device 20 is installed at a position close to the opening of the trash can 30, and a movable nano tape is set at the opening of the trash can. The second side wall 140 is adhered to the nano tape, and the bag opening 101 is automatically opened by moving in a direction away from the first side wall 130. The connection between the support member 220 and the bagging mechanism 200 can be a direct connection between the two or an indirect connection. For example, when the bag fixing device 20 is installed on the trash can 30, the support member 220 and the bagging mechanism 200 are respectively connected to the trash can 30, thereby realizing an indirect connection between the support member 220 and the bagging mechanism 200.

[0052] Specifically, the bagging mechanism 200 is used to stop the first side wall 130 of the bag body 100, the pushing mechanism 210 is used to apply force to the first side wall 130 of the bag body 100 so that the first side wall 130 abuts against the bagging mechanism 200, the fixing column 231 is used to pass through the string hole 102 of the bag body 100 so that multiple bag bodies 100 can be fixed on the fixing column 231, and the bag outlet 232 is used to allow the second side wall 140 of the bag body 100 to pass through. In this way, when the second side wall 140 passes through the bag outlet 232 and moves away from the first side wall 130, the first side wall 130 is stopped by the bagging mechanism 200 and restricted on the fixing column 231, so that the second side wall 140 is away from the first side wall 130, thereby realizing the opening of the bag outlet 101.

[0053] In addition, the support member 220 is used to support the propulsion mechanism 210 , so that the propulsion mechanism 210 can apply force to the first side wall 130 of the bag body 100 , so that the first side wall 130 is closely attached to the bagging mechanism 200 .

[0054] In order to apply force to the first side wall 130 , the propulsion mechanism 210 may provide force to the first side wall 130 in an elastic manner, or may provide force to the first side wall 130 through a drive structure such as a cylinder or a motor.

In this embodiment, when the bag body 100 is not installed in the bag fixing device 20, the propulsion plate 212 abuts against the bagging mechanism 200 under the elastic force of the elastic component 211, and when the bag body 100 is strung on the fixing column 231, the propulsion plate 212 abuts against the first side wall 130 of the bag body 100 under the elastic force of the elastic component 211, so that the first side wall 130 is closely attached to the bagging mechanism 200. In this embodiment, the elastic component 211 is supported by the support member 220 to provide elastic force for the propulsion plate 212 , so that the propulsion plate 212 applies force to the first side wall 130 of the bag body 100 under the elastic force of the elastic component 211 .

[0056] In other embodiments, the propulsion mechanism includes a propulsion motor and a propulsion plate, the propulsion motor is connected to the support member, the propulsion motor and the propulsion plate are drivingly connected, and the propulsion plate abuts against the bagging mechanism under the drive of the propulsion motor. In this embodiment, the propulsion plate applies force to the first side wall under the drive of the propulsion motor so that the first side wall is closely attached to the bagging mechanism.

[0061] In one embodiment, there are multiple bags, the bag mouth ends 110 of the bag bodies 100 are stacked in sequence, and the string holes 102 are aligned in sequence, the fixing columns 231 are inserted into the string holes 102, the propulsion mechanism 210 abuts against the first side wall 130 of the last bag body, and applies force to the first side wall 130 so that the first side wall 130 of the first bag body abuts against the bagging mechanism 200; after the first bag body is separated from the fixing columns 231, the first side wall 130 of the bag body behind the first bag body abuts against the bagging mechanism 200 under the action of the propulsion mechanism 210.

[0062] In this embodiment, each bag body is aligned and stacked, and is strung on the fixed column 231 through the string hole 102. The bag body abutting against the bagging mechanism 200 is the first bag body, the bag body behind the first bag body is the second bag body, and so on. The bag body farthest from the bagging mechanism 200 is the last bag body. The pushing mechanism 210 applies force to the last bag body so that each bag body can be closely abutted against each other, so that the first bag body is tightly abutted against the bagging mechanism 200. In this way, when the first bag body is torn off from the fixed column 231 by force, the first bag body is separated from the bagging mechanism 200, and the first side wall 130 of the original second bag body abuts against the bagging mechanism 200 under the action of the force of the pushing mechanism 210, and the second side wall 140 passes through the bag outlet 232 and is exposed. In this way, the original second bag body becomes the first bag body and is exposed through the bag outlet 232, which is convenient for the user to tear it off.

[0063] In one embodiment, if Figures 3 to 5 As shown, the bagging mechanism 200 includes a box body 230, the inner surface of one side of the box body 230 is set as a stop surface 233, the fixing column 231 is protruded on the stop surface 233, the number of the fixing columns 231 is two, which are symmetrically arranged on both sides of the stop surface 233, the stop surface 233 is provided with the bag outlet 232, the support member 220 is connected to the box body 230, and the propulsion mechanism 210 includes an elastic component 211 and a propulsion plate 212, one end of the elastic component 211 is connected to the support member 220, and the other end of the elastic component 211 is connected to the propulsion plate 212, the propulsion plate 212 is movably arranged in the box body 230, and the propulsion plate 212 abuts against the stop surface 233 under the elastic force of the elastic component 211.

[0064] In this embodiment, the bag installation structure is applied to the trash can 30 for further explanation. Figure 7 , Figure 8 and Fig. 9 As shown, the trash can 30 has an upper cover 310 with a hollow structure at the barrel mouth 301 of the barrel body 300, and the box body 230 is arranged on one side of the upper cover 310. Specifically, a mounting cavity 315 is opened on one side of the upper cover 310, and the box body 230 is arranged in the mounting cavity 315. The bag outlet 232 faces the middle of the upper cover 310, and a tape fixing seat 320 is arranged on the other side of the upper cover 310. A driving motor and a guide rail 311 are arranged on the upper cover 310. The guide rail is arranged from one side of the upper cover 310 to the other side. The driving motor is connected to the tape fixing seat 320 for driving. The tape fixing seat 320 is slidably arranged on the guide rail, and a nano tape 321 is arranged on the side of the tape fixing seat 320 facing the box body 230. Please refer to the following figure for details. Fig. 9 and Fig.10The upper cover 310 includes a cover body 312 and a support frame 313. The support frame 313 is detachably connected to the top of the barrel body 350. The cover body 312 is connected to the support frame 313. The cover body 312 is provided with a delivery port 319. The upper cover door 316 is rotatably arranged on the cover body 312. The upper cover door 316 is movable to close the delivery port 319. The support frame 313 is provided with two guide rails 311. The two guide rails 311 are respectively arranged on both sides of the support frame 313. The tape fixing seat 320 The number is two, the two tape fixing seats 320 are connected to a movable seat 322, and movable holes 323 are provided on both sides of the movable seat 322. Each guide rail 311 is arranged in a movable hole 323, and the movable seat 322 is slidably arranged on the guide rail 311 through the movable hole 323. One end of the guide rail 311 is arranged close to the bag fixing device 20, and the other end of the guide rail 311 is arranged away from the bag fixing device 20. In this embodiment, the guide rail 311 is cylindrical, and the movable hole 3 23 is a circular hole. A driving motor 410, a transmission gear 430, two pulleys 440 and a belt 420 are also provided on the supporting frame. The driving motor 410 is provided on the supporting frame 313. The transmission gear 430 and the two pulleys 440 are respectively rotatably provided on the supporting frame 313. The driving motor 410 is drivingly connected to the transmission gear 430. The transmission gear 430 and the pulley 440 are connected via a transmission shaft. The transmission gear 430 and the pulley 440 are both provided on the transmission shaft. The two pulleys 440 are respectively provided on a side of the supporting frame 313 close to the bag fixing device 20 and a side away from the bag fixing device 20. The belt 420 is wound on the two pulleys 440. The belt 420 is connected to the movable seat 322. In this embodiment, there are two belts 420, and the two belts 420 are respectively connected to the movable seat 322.

[0065] In this way, when the driving motor 410 is working, the transmission gear 430 drives the pulley 440 to rotate, the pulley 440 drives the belt 420 to transmit, the belt 420 drives the slider to move along the slider, and the slider drives the tape fixing seat 320 to move, so that the tape fixing seat 320 is close to the bag fixing device 20 or away from the bag fixing device 20. When the tape fixing seat 320 is close to the bag fixing device 20, the nano tape 321 on the tape fixing seat 320 abuts against the bag on the bag fixing device 20 to adhere the bag. Subsequently, when the tape fixing seat 320 is away from the bag fixing device 20, the nano tape 321 moves away from the bag fixing device 20 with the tape fixing seat 320. The bag fixing device 20 fixes the side wall of one side of the bag, and the nano tape 321 adheres to the side wall of the other side of the bag, so that the side walls on both sides of the bag opening are separated, thereby realizing the opening of the bag.

[0066] Please combine Figure 1, Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.10 When the tape fixing seat 320 moves toward the direction close to the box body 230, the nano tape 321 abuts against the second side wall 140, and the nano tape 321 adheres to the second side wall 140. Then, the tape fixing seat 320 moves in the opposite direction, so that the second side wall 140 moves in the direction away from the first side wall 130, and the first side wall 130 abuts against the blocking surfaces 233 on both sides of the bag outlet 232. And under the restriction of the fixing column 231, the first side wall 130 will not move with the movement of the second side wall 140. Therefore, the second side wall 140 is separated from the first side wall 130, so that the bag opening 101 is opened. In this way, the bag opening 101 can be opened in the trash can 30, so that the garbage put into the trash can 30 through the upper cover 310 can fall into the bag body 100. In the process of loading garbage, the nano tape 321 continues to support the second side wall 140, so that the bag opening 101 can remain open. Please combine Figure 1 and Figure 2 , Figure 2 The middle bag body 100 is in an open state. At this time, the second folding portion 141 is unfolded as the second side wall 140 is opened. However, since the first folding portion 131 is still strung on the fixing column, the first folding portion 131 remains in a folded state and does not unfold.

[0067] It is worth mentioning that the material of the nano tape is a composite of acrylic and PET (Polyethyleneterephthalate). For example, the nano tape includes an acrylic layer and a PET layer. A large number of nano-scale micropores are opened on the surface of the nano tape, which makes the nano tape have super strong adsorption force and can be easily adhered to the surface of various objects. It can adhere to the bag with strong adhesion and can be reused. When the bag is pulled by external force, it can be detached from the nano tape, so that the bag can remain intact when it is detached from the nano tape.

[0068] In this embodiment, the second side wall 140 of the bag body 100 is arranged in the bag outlet 232, or is arranged on the outside of the box body 230 through the bag outlet 232. In this way, the second side wall 140 can be adhered by the nano tape 321 and move with the movement of the tape fixing seat 320. The middle part and the bottom end 120 of the bag body 100 are folded and stored in the box body 230. When the second side wall 140 is pulled out by the nano tape 321, the middle part and the bottom end 120 of the bag body 100 are pulled out through the bag outlet 232, thereby opening the bag mouth 101 of the bag body 100, and the middle part and the bottom end 120 of the bag body 100 are drooped after being pulled out of the bag outlet 232, and open as the bag mouth 101 opens, so as to facilitate the storage of garbage.

[0069] In addition, in this embodiment, if Figures 7 to 9 As shown, a heat-sealing adhesive strip 330 is arranged below the adhesive tape fixing seat 320, and a hot pressing piece 340 is arranged below the box body 230, and the heat-sealing adhesive strip 330 is movably abutted against the hot pressing piece 340. When the garbage is stored to a certain extent, the user controls the driving motor to work by pressing a button on the garbage can 30, and drives the adhesive tape fixing seat 320 to move toward the box body 230, so that the heat-sealing adhesive strip 320 is close to the hot pressing piece 340, and the hot pressing piece 340 is heated after being energized, and the first side wall 130 and the second side wall 140 of the bag body 100 are heat-pressed and sealed under the pressure of the heat-sealing adhesive strip and the hot pressing piece on both sides, so that the bag mouth 101 is closed, thereby completing the collection of garbage, and then the adhesive tape fixing seat 320 moves away from the box body 230. At this time, the user can take out the bag body 100 with the heat-sealed bag opening 101 through the material extraction port 303 on one side of the trash can 30. Subsequently, the next bag body 100 abuts against the stopping surface 233 of the box body 230 under the action of the propulsion mechanism 210, and the second side wall 140 is exposed at the bag outlet 232. In this way, when the tape fixing seat 320 approaches the box body 230 again, the nano tape 321 can open the bag body 100 by adsorbing the second side wall 140, so that the garbage can be stored.

[0070] When the bag is used up, in order to replenish the bag, in one embodiment, Figure 4 and Figure 5 As shown, the support member 220 is detachably disposed on the box body 230. In one embodiment, a feed port 234 is provided on a side of the box body 230 away from the bag outlet 232. Insertion grooves 235 are provided on the side walls on both sides of the feed port 234. Both ends of the support member 220 are detachably inserted into the insertion grooves 235. In this way, by inserting the two ends of the support member 220 into the insertion groove 235, the support member 220 is fixed on the box body 230. When the bag body 100, the elastic component 211 and the push plate 212 need to be disassembled, the two ends of the support member 220 are separated from the insertion groove 235. In this way, the support member 220 can be removed from the box body 230, and the elastic component 211 and the push plate 212 can also be removed, so that the bag body 100 can be loaded into the box body 230. The bag body 100 enters the box body through the feed port 234 and is fixed on the fixing column 231 through the string hole 102. Subsequently, the elastic component 211 and the push plate 212 are installed so that the push plate 212 abuts against the second side wall 140 of the bag body 100. The two ends of the support member 220 are installed into the insertion groove 235, so that the bag body 100 is squeezed and fixed. In addition, the support member 220 can effectively support the elastic component 211 and the push plate 212.

[0071] In order to realize the installation and removal of the support member 220, in one embodiment, as Figure 5As shown, sliding grooves 221 are respectively provided at both ends of the support member 220, and an insert piece 222 is slidably provided in the sliding groove 221. When one end of the insert piece 222 slides to the outside of the sliding groove 221, it can be inserted into the plug-in groove 235. In this way, the support member 220 can be fixed on the box body 230 by sliding the insert piece 222, and when the insert piece 222 slides to be out of the plug-in groove 235, the support member 220 can be detached from the box body 230 and can be removed from the box body 230.

[0072] In one embodiment, the plug 222 is connected to the support member 220 through an elastic member (blocked in the figure and not shown), for example, the elastic member is a spring. In one embodiment, a limiting portion is provided at the end of the sliding slot 221 close to the plug-in slot 235, and an abutting portion is provided on the protrusion of the end of the plug 222 away from the plug-in slot 235. The abutting portion movably abuts against the limiting portion, and the limiting portion is used to limit the plug 222 from detaching from the plug-in slot 235. Specifically, the elastic member is used to provide the plug 222 with an elastic force toward the plug-in slot 235, that is, the elastic force direction of the elastic member is toward the plug-in slot 235. In this way, the plug 222 is automatically inserted into the plug-in slot 235 under the action of the elastic member, and the limiting portion abuts against the abutting portion, which can limit the plug 222 from being completely inserted. The sliding slot 221 is completely slid out to prevent the insert piece 222 from being separated from the sliding slot 221. When the support member 220 needs to be disassembled, a force is applied to the insert piece 222 in a direction away from the plug-in slot 235 to overcome the elastic force of the elastic member, so that the insert piece 222 moves in a direction away from the plug-in slot 235, so that the insert piece 222 is separated from the plug-in slot 235, and the support member 220 can be removed from the box body 230; when the support member 220 needs to be installed, a force is applied to the insert piece 222 so that the insert piece 222 shrinks to the inner side of the end of the support member 220, and the support member 220 is installed on the box body 230, and then the insert piece 222 is released, and the insert piece 222 is inserted into the plug-in slot 235 under the elastic force of the elastic member, thereby realizing the installation of the support member 220.

[0073] In order to achieve the thrust on the bag body 100, in one embodiment, as Figure 4 and Figure 5As shown, the elastic component 211 includes an elastic member (blocked in the figure and not shown) and a rotating support plate 213. There are two rotating support plates 213. One end of the rotating support plate 213 is rotatably connected to the support member 220, and the other end of the rotating support plate 213 abuts against a side of the pushing plate 212 facing away from the stopping surface 233. One end of the elastic member is connected to the rotating support plate 213, and the other end of the elastic member is connected to the support member 220. In this embodiment, the two rotating support plates 213 are arranged in a herringbone shape, and the opened ends of the two rotating support plates 213 abut against the pushing plate 212. In this way, the two rotating support plates 213 push the pushing plate 212 in a direction away from the support member 220 under the elastic force of the elastic member, so that the pushing plate 212 can apply force to the bag body 100.

[0074] In one embodiment, a rotating shaft 223 is provided on the support member 220, and a sleeve portion is provided at one end of the rotating support plate 213 close to the support member 220. The sleeve portion is sleeved on the rotating shaft 223 and is rotatably provided on the rotating shaft. In this embodiment, the elastic member is a torsion spring, which is sleeved on the rotating shaft, and its two ends are respectively connected to the support member 220 and the rotating support plate 213. In this way, under the elastic force of the torsion spring, the rotating support plate 213 can apply force to the propulsion plate 212, so that the propulsion plate 212 applies a force toward the stopping surface 233 to the bag body 100.

[0075] In order to achieve the thrust on the bag body, in one embodiment, the elastic component includes a spring, one end of the spring is connected to the thrust plate, and the other end of the spring is connected to the support member, and the elastic force direction of the spring is toward the stop surface of the box body. In this way, through the elastic force of the spring on the thrust plate, the thrust plate can apply force to the bag body, pushing the first side wall of the bag body to abut against the stop surface of the box body.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
