Technical Field
[0001] The utility model relates to the technical field of flexible intermediate bulk containers, in particular to a four-piece bottleneck inner bag girdle anti-expansion flexible intermediate bulk container. Background Art
[0002] A flexible intermediate bulk container is a large flexible packaging bag used for transporting and storing bulk materials, which has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient strength in structure. Since the flexible intermediate bulk container is very convenient for loading and unloading, the loading and unloading efficiency is significantly improved, and it has developed rapidly in recent years.
[0003] The four-piece bottleneck inner bag girdle anti-expansion flexible intermediate bulk container mainly means that the bag body of the flexible intermediate bulk container is surrounded by four identical sides, and the inner bag is provided with a bottleneck, which can better and more accurately accommodate and protect articles, and a girdle is arranged on the outer surface of the flexible intermediate bulk container, which can play a certain role in preventing expansion.
[0004] The inventor found in daily work that when the existing four-piece bottleneck inner bag girdle anti-expansion flexible intermediate bulk container is in the process of loading materials, a girdle is usually used for reinforcement and anti-expansion. However, when loading heavier articles, the reinforcement effect of the girdle becomes poor, and the girdle part is damaged, resulting in the continuous expansion of the flexible intermediate bulk container, and the loading capacity cannot be controlled, which is easy to cause excessive expansion and damage to the flexible intermediate bulk container. Furthermore, the existing four-piece bottleneck inner bag girdle anti-expansion flexible intermediate bulk container is not convenient for controlling the loading capacity and is prone to the problem of excessive expansion and damage. Summary of the Utility Model

Belt body. Detailed implementation manner
[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a four-piece bottleneck inner bag belt anti-expansion container bag, including an outer bag body 1 and a protection device 5. An inner bag body 2 is installed on the inner wall of the outer bag body 1. Four suspension straps 4 are arranged on the surface of the outer bag body 1. A bottleneck opening 3 is arranged on the surface of the inner bag body 2. A belt body 6 is arranged on the outside of the outer bag body 1. The protection device 5 is arranged on the surface of the outer bag body 1.
[0022] Next, specifically describe the specific settings and functions of its protection device 5 and auxiliary component 59.
[0023] Specifically, the protection device 5 includes a first intercepting rod 51 and a second intercepting rod 52. The number of the first intercepting rod 51 and the second intercepting rod 52 is two respectively. The two first intercepting rods 51 and the second intercepting rods 52 are respectively fixedly connected to the two side surfaces of the outer bag body 1. Two first sliding rods 53 and second sliding rods 54 are respectively slidably connected to the inner walls of the first intercepting rod 51 and the second intercepting rod 52. One ends of the first sliding rod 53 and the second sliding rod 54 are respectively rotatably connected to a first hollow sleeve 55 and a second hollow sleeve 56. A first extension rod 57 and a second extension rod 58 are slidably connected to the inner walls of the first hollow sleeve 55 and the second hollow sleeve 56. A connection component 512 is arranged on the surfaces of the first extension rod 57 and the second extension rod 58.
[0024] In this implementation scheme: when loading materials, the first extension rod 57 and the second extension rod 58 are pulled out from the first hollow sleeve 55 and the second hollow sleeve 56, and then the first extension rod 57 and the second extension rod 58 are connected through the connection component 512. When loading to a certain extent and the inner bag body 2 and the outer bag body 1 expand, the outer bag body 1 will squeeze the first intercepting rod 51, the second intercepting rod 52, the first extension rod 57 and the second extension rod 58. At this time, the first extension rod 57 and the second extension rod 58 slide in the first hollow sleeve 55 and the second hollow sleeve 56, and the first sliding rod 53 and the second sliding rod 54 slide in the first intercepting rod 51 and the second intercepting rod 52. When they all slide to the point where they cannot slide anymore, the expansion range of the outer bag body 1 can be restricted, thereby protecting it.
[0025] Specifically, the connecting component 512 includes a connecting rod 5121. The connecting rod 5121 is slidably connected to the inner wall of the first extension rod 57. A jack is provided on the surface of the second extension rod 58. The connecting rod 5121 is inserted into the inner wall of the jack. When the first extension rod 57 and the second extension rod 58 need to be connected, the connecting rod 5121 is inserted into the jack on the surface of the second extension rod 58 to complete the connection.
[0026] Specifically, a third spring 5122 is sleeved on the surface of the connecting rod 5121. Both ends of the third spring 5122 are fixedly connected to the surfaces of the connecting rod 5121 and the first extension rod 57 respectively.
[0027] In this embodiment: The third spring 5122 can improve the binding effect of the connecting rod 5121 in the jack on the surface of the second extension rod 58.
[0028] Specifically, a first spring 510 is fixedly connected to the side of the first extension rod 57 corresponding to the inner wall of the first hollow sleeve 55, and a second spring 511 is fixedly connected to the side of the second extension rod 58 corresponding to the inner wall of the second hollow sleeve 56. The first spring 510 and the second spring 511 can control the reset of the first extension rod 57 and the second extension rod 58.
[0029] Specifically, auxiliary components 59 are respectively arranged on the surfaces of the first intercepting rod 51, the second intercepting rod 52, the first hollow sleeve 55 and the second hollow sleeve 56. The auxiliary component 59 includes a first reinforcing belt 591 and a second reinforcing belt 593. The numbers of the first reinforcing belt 591 and the second reinforcing belt 593 are four respectively. The four first reinforcing belts 591 are fixedly connected to the surfaces of the first intercepting rod 51 and the second intercepting rod 52 in pairs, and the four second reinforcing belts 593 are fixedly connected to the surfaces of the first hollow sleeve 55 and the second hollow sleeve 56 in pairs.
[0030] In this embodiment: The first reinforcing belt 591 cooperating with the second reinforcing belt 593 can cooperate with the first intercepting rod 51, the second intercepting rod 52, the first hollow sleeve 55 and the second hollow sleeve 56 for interception, improving the interception effect.
[0031] Specifically, a first auxiliary belt 592 is fixedly connected to the surfaces of two first reinforcing belts 591, and a second auxiliary belt 595 is fixedly connected to the surface of the second reinforcing belt 593 on the surface of the first hollow sleeve 55. The second auxiliary belt 595 is installed on the second auxiliary belt 595 on the surface of the second hollow sleeve 56 through a magic tape.
[0032] In this embodiment: The first auxiliary belt 592 and the second auxiliary belt 595 cooperating with the first reinforcing belt 591 and the second reinforcing belt 593 can increase the overall interception range.
[0033] Working principle: When loading, the connecting rod 5121 is pushed, and the third spring 5122 is stressed. Subsequently, the first extension rod 57 and the second extension rod 58 are pulled out from the first hollow sleeve 55 and the second hollow sleeve 56, and the first spring 510 and the second spring 511 are stressed. When the first extension rod 57 and the second extension rod 58 are pulled to a certain position, the connecting rod 5121 is released, and the third spring 5122 drives the connecting rod 5121 to reset and insert into the jack on the surface of the second extension rod 58. Subsequently, the material is added into the inner bag body 2 from the bottleneck 3. When the loading reaches a certain level, the inner bag body 2 and the outer bag body 1 expand, and the outer bag body 1 will squeeze the first intercepting rod 51, the second intercepting rod 52, the first extension rod 57, and the second extension rod 58. At this time, the first extension rod 57 and the second extension rod 58 slide in the first hollow sleeve 55 and the second hollow sleeve 56, and the first sliding rod 53 and the second sliding rod 54 slide in the first intercepting rod 51 and the second intercepting rod 52. When they all slide to the point where they cannot slide anymore, the two groups of the first intercepting rod 51 and the second intercepting rod 52 cooperate with the two first reinforcing belts 591 and the first auxiliary belt 592 respectively, and the two groups of the first hollow sleeve 55 and the second hollow sleeve 56 cooperate with the second reinforcing belt 593 and the first reinforcing belt 591 to intercept the four sides of the outer bag body 1, which can limit the expansion range of the outer bag body 1, thereby protecting it. By setting the protection device 5 and the auxiliary component 59, the expansion range during the loading of the four-piece bottleneck inner bag surrounding belt anti-expansion bulk bag can be restricted, which can reduce the damage or displacement of the goods caused by the excessive expansion of the bulk bag, extend its service life, help maintain the consistency of the bulk bag size, facilitate transportation and warehousing management, and thus improve the overall practicality of the bulk bag belt.
