[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides asFigures 1-5 An anti-cracking open bag shown in the figure includes an open bag body 1, an outer wall of the open bag body 1 is provided with an inner cavity provided with a support structure 3, the support structure 3 includes a first support rod 301 and a second support rod 302, the first support rod 301 is movably arranged in the inner cavity of the open bag body 1, the second support rod 302 is movably sleeved on the end of the first support rod 301, and the end of the second support rod 302 away from the first support rod 301 is sleeved with a squeezing ball 303, the number of the first support rods 301 is two, the two first support rods 301 are in a cross shape, and the squeezing ball 303 is any one of elastic rubber or elastic silicone.

[0022] like Figure 3 As shown in, the first support rod 301 is cross-shapedly arranged at the bottom end of the inner cavity of the open-mouth bag main body 1, so that the end of the first support rod 301 can support the end of the bottom end of the inner cavity of the open-mouth bag main body 1, thereby providing tangible support to the bottom end of the open-mouth bag main body 1, and at the same time enabling objects placed in the inner cavity of the open-mouth bag main body 1 to be better supported, effectively improving the bearing capacity of the open-mouth bag main body 1 and reducing the probability of cracking and damage of the open-mouth bag main body 1. The second support rod 302 is sleeved on the end of the first support rod 301, and the second support rod 302 and the first support rod 301 are threadedly connected. By rotating the second support rod 302, the overall length between the second support rod 302 and the first support rod 301 can be adjusted. The second support rod 302 is movably adjustable, so that the first support rod 301 and the second support rod 302 The overall length of the first support rod 301 and the second support rod 302 can be adjusted according to the setting of the inner cavity width of the open-mouth bag main body 1, so that the end of the second support rod 302 away from the first support rod 301 can better support the inner cavity end of the open-mouth bag main body 1, and a squeezing ball 303 is sleeved on the end of the second support rod 302 away from the first support rod 301. The squeezing ball 303 is sleeved on the end of the second support rod 302 using its own elasticity, and is convenient for disassembly and assembly. The setting of the squeezing ball 303 is convenient for improving the safety of the second support rod 302 in supporting the open-mouth bag main body 1, and avoiding the phenomenon that the end of the second support rod 302 directly squeezes the open-mouth bag main body 1 and causes the inner cavity end of the open-mouth bag main body 1 to be subjected to greater force, thereby effectively enhancing the effectiveness and safety of supporting the bottom end of the inner cavity of the open-mouth bag main body 1.

[0023] The support structure 3 further includes a connecting rod 304 and an extrusion block 305 . The connecting rod 304 is inserted and embedded in the middle of the first support rod 301 through the extrusion block 305 . The extrusion block 305 is fixedly disposed in the inner cavity in the middle of the first support rod 301 .

[0024] like Figure 5As shown in the figure, a through groove is formed in the middle of the first support rod 301 where it intersects. The extrusion block 305 is fixedly arranged in the inner cavity of the through groove. The two first support rods 301 are arranged vertically, facilitating the change of the intersection angle of the two first support rods 301, and thus facilitating the adjustment of the intersection angle of the first support rods 301 according to the width of the open-top bag body 1. The extrusion block 305 is any one of elastic rubber or elastic silica gel. The bottom end of the connecting rod 304 is sleeved with an extrusion ball 303. The setting of the extrusion block 305 provides a limit for the insertion of the connecting rod 304 into the through groove, enabling the first support rod 301 to maintain the stability of the intersection angle by the friction between the connecting rod 304 and the extrusion block 305 without external force. Moreover, an extrusion ball 303 is also sleeved at the bottom end of the connecting rod 304 to prevent the connecting rod 304 from detaching from the inner cavity of the through groove, ensuring the effectiveness of the insertion connection between the connecting rod 304 and the first support rod 301.

[0025] The outer wall and the inner wall of the open-top bag body 1 are provided with a protection structure 2. The protection structure 2 includes a first protection layer 201, a second protection layer 202, and a separation component. The first protection layer 201 is fixedly arranged on the outer wall of the open-top bag body 1, the second protection layer 202 is fixedly arranged on the inner wall of the open-top bag body 1, and the separation component is arranged above the first support rod 301 and the second support rod 302. The separation component includes a bottom pad 203 and two through holes 204. The two through holes 204 are symmetrically formed at the top end of the bottom pad 203. The bottom pad 203 is movably arranged in the inner cavity of the open-top bag body 1 and is located above the first support rod 301 and the second support rod 302.

[0026] As Figure 1 、 Figure 2 and Figure 3 As shown in the figure, both the first protection layer 201 and the second protection layer 202 are polyvinyl chloride elastic waterproof coatings, which have good waterproof performance, enabling the open-top bag body 1 to have excellent waterproof performance, thus avoiding the cracking phenomenon caused by rain, effectively improving the anti-cracking performance of the open-top bag body 1, extending the service life of the open-top bag body 1, reducing the use cost of the open-top bag body 1. The bottom pad 203 is any one of elastic rubber or elastic silica gel. The setting of the bottom pad 203 can separate the first support rod 301 and the second support rod 302, so that when an object is placed in the open-top bag body 1, it can avoid direct contact with the first support rod 301, playing a protective role for the first support rod 301. At the same time, with the setting of the bottom pad 203, the force on the first support rod 301 can be made more uniform after the object is placed, thereby improving the force uniformity of the open-top bag body 1 and further reducing the probability of cracking of the open-top bag body 1. Moreover, through holes 204 are formed at the top end of the bottom pad 203, facilitating the taking and placing of the bottom pad 203 through the insertion into the through holes 204, providing a space support for the taking and placing of the bottom pad 203.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
