Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric products, in particular to a non-woven fabric insulation box. Background Art

[0002] Non-woven fabrics, also known as nonwovens, nonwoven fabrics, and non-woven fabrics, are made of directional or randomly arranged fibers through friction, adhesion, bonding or a combination of these methods. They have the characteristics of light weight, softness, and wear resistance. They are often used in various fields, such as insulated boxes of tableware.

[0003] Existing non-woven insulation boxes are designed into insulation boxes of different specifications according to the size of tableware. When a larger insulation box is loaded with smaller tableware, the tableware will be unstable. There is a lack of an insulation box that can meet the needs of placing tableware of different sizes and can be stably fixed. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a non-woven insulation box, which solves the problem that the existing non-woven insulation box has relatively poor compatibility and stability when placing tableware of different volumes.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a non-woven fabric insulation box, including a box body, a storage cavity with an upward opening formed on the box body, a plurality of guide grooves are arranged at circumferential intervals of the storage cavity, the guide grooves are arranged along the height direction of the box body, a guide rope is passed through the guide groove, one end of the guide rope is connected to the bottom of the storage cavity, and the other end extends out of the guide groove.

[0006] Furthermore, the guide groove is arranged on the outside of the box body or on the inner wall of the storage cavity.

[0007] By adopting the above technical solution, the guide grooves are arranged on the outside and inside of the box body, and multiple guide ropes can be pulled up to squeeze the box body inward to deform, so that the box body is close to the tableware, effectively improving the stability of the tableware fixed in the box body.

[0008] Furthermore, a guide strip is provided on the inner wall of the storage cavity, and a guide groove is formed inside the guide strip.

[0009] By adopting the above technical solution and providing the guide strip, it is convenient to form a guide groove inside the storage cavity.

[0010] Furthermore, the box body also includes a tightening mechanism, which is used to tighten and fix the end of the guide rope extending out of the guide groove.

[0011] By adopting the above technical solution, by adding a tightening mechanism, it is more convenient to fix the free end of the guiding rope (the free end is the end where the guiding rope extends out of the guiding groove). Furthermore, after the guiding rope is lifted upward to make the box body close to the tableware, by fixing the guiding rope, the fitting state between the box body and the tableware can be maintained.

[0012] Furthermore, the tightening mechanism includes a bottom plate and a pressing plate. A plurality of through holes corresponding to the guiding rope are circumferentially and spacedly arranged on the bottom plate. The distance between the pressing plate and the bottom plate is adjustable to press the guiding rope against the bottom plate.

[0013] By adopting the above technical solution, after the pressing plate and the bottom plate are tightened, the guiding rope can be fixed in the through holes of the bottom plate to maintain the tightening of the guiding rope on the box body.

[0014] Furthermore, the pressing plate is provided with a screw rod. The pressing plate is screwed on the bottom plate through the screw rod. The pressing plate is provided with an operation protrusion.

[0015] By adopting the above technical solution, the setting of the operation protrusion facilitates the operation of rotating the pressing plate by personnel.

[0016] Furthermore, the tightening mechanism includes a locking block and a locking rod. A fixing gap for accommodating a plurality of guiding ropes is formed between the locking rod and the locking block. The insertion rod is adjustably arranged through the locking block to adjust the distance of the fixing gap.

[0017] By adopting the above technical solution, the design with adjustable distance between the locking block and the locking rod can facilitate the locking of the guiding rope entering the fixing gap.

[0018] Furthermore, a locking hole is transversely opened on the locking block. The locking rod is movably arranged through the locking hole. A communication hole is vertically opened on the locking block. An insertion rod is elastically and movably arranged in the communication hole. A pull rod is arranged at the upper end of the insertion rod outside the locking block. The lower end of the insertion rod extends into the locking hole and abuts and tightens against the locking rod.

[0019] By adopting the above technical solution, by the elastic tightening method between the insertion rod and the locking rod, it is convenient to fix the relative position of the locking rod on the locking block.

[0020] Furthermore, an elastic member is arranged between the pull rod and the locking block to apply an elastic acting force towards the locking rod to the insertion rod.

[0021] Furthermore, the box body includes a waterproof outer layer, an inner layer and a heat insulation layer arranged between the two.

[0022] Compared with the prior art, the advantages of the present utility model are as follows:

[0023] 1. In the utility model, a guide groove is arranged at intervals on the inner wall of the storage cavity inside the box body, and a guide rope is passed through the guide groove. After the lower end of the guide rope is connected to the bottom of the storage cavity, the other end extends out of the guide groove. In this way, when the box body is storing tableware, the guide rope can be pulled at one end outside the guide groove to squeeze the box body, so that the box body can be deformed and stably fit on tableware of different shapes, effectively avoiding the situation that the volume of the tableware and the box body do not match, resulting in unstable storage of the tableware, reducing the shaking of the tableware during storage, and making it more convenient for people to carry.

[0024] 2. In the utility model, the guide rope spacer ring is arranged on the storage cavity. When the guide rope is pulled and folded, the tableware is mainly supported and lifted by the guide rope. Compared with the traditional way that the guide rope is arranged at the opening of the box body, this embodiment transfers the force exerted by the tableware on the box body to the guide rope, which greatly improves the tensile strength and support strength of the box body and effectively avoids the box body from being torn and damaged when being pulled and carried.

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] Reference Figure 1A non-woven insulation box includes a box body 100. The box body 100 can be a prism, a cylinder or other shapes. Taking a cylinder as an example, it has a storage cavity opening upward. The storage cavity is provided with guide grooves at intervals along its height direction. A guide rope 120 is passed through the guide groove. One end of the guide rope 120 is connected to the bottom of the storage cavity, and the other end extends out of the guide groove (for the convenience of the following description, the section extending out of the guide groove is called a free end). When tableware is placed in the storage cavity, the free ends of multiple guide ropes 120 can be lifted, and the guide ropes 120 drive the box body 100 to deform and fit on the surface of the tableware, so that the box body 100 is adapted to the surface shape of the tableware, thereby preventing the tableware from shaking in the box body 100 and improving the fixation stability of the product.

[0036] In this embodiment, the guide grooves can be arranged at intervals on the outside or inside of the box body 100. When located on the outside, multiple guide grooves are opened on the surface of the box body 100. When located on the inside, they can be arranged on the inner wall of the storage cavity or on the inside of the material of the box body 100. Figure 1 and 2 In the figure, the guide groove includes a plurality of guide bars 110 , guide grooves are formed in the guide bars 110 , and guide ropes 120 are passed through the guide bars 110 .

[0037] In this embodiment, when the free ends of the multiple guide ropes 120 are pulled to make the box body 100 deform and fit the tableware, the free ends of the multiple guide ropes 120 can be knotted to maintain the shape of the box body 100 fixed by the guide ropes 120. Furthermore, in order to facilitate opening or closing the opening of the box body 100, a tightening mechanism is also provided on the box body 100, and the free ends of the multiple guide ropes 120 are fixed by the tightening mechanism to facilitate opening or closing the box body 100.

[0038] Specifically, refer to Figure 2 and 3 As an embodiment of the tightening mechanism, the tightening mechanism includes a base film 200 and a pressing plate 220. The circumferential spacing ring of the base film 200 is provided with a plurality of through holes 210 corresponding to the guide ropes 120. The free ends of the guide ropes 120 can be inserted into the through holes 210. The distance between the pressing plate 220 and the base film 200 is adjustable. In this way, the distance between the pressing plate 220 and the base film 200 is reduced, and the guide ropes 120 are pressed against the base film 200 by using the pressing plate 220, thereby realizing the fixing of multiple guide ropes 120.

[0039] Reference Figure 3, as a way to adjust the distance between the pressing piece 220 and the bottom piece 200, the two can be connected by a screw rod 230. Specifically, a screw rod 230 is provided at the center of the pressing piece 220, and a screw hole is provided at the corresponding center position of the bottom piece 200. By rotating the screw rod 230 in the screw hole, the distance between the pressing piece 220 and the bottom piece 200 can be adjusted, so as to achieve the purpose of tightening and fixing multiple guide ropes 120.

[0040] Furthermore, an operation protrusion can be provided at the upper end of the pressing piece 220 so that the operator can operate and rotate the pressing piece 220 through the operation protrusion.

[0041] Even further, in order to prevent the separation between the pressing piece 220 and the bottom piece 200, an anti-separation piece 231 can also be provided at the lower end of the screw rod 230. Through the anti-separation piece 231, the separation between the screw rod 230 and the screw hole can be prevented, and the loss after their separation can be avoided.

[0042] As another embodiment of adjusting the distance between the pressing piece 220 and the bottom piece 200, the two can also be connected by a commonly used buckle in the prior art, and the disassembly and separation of the two can be realized through the clamping connection between the buckle and the card slot.

[0043] Referring to Figure 4 and 5 , as an embodiment of the tightening mechanism, the tightening mechanism includes a locking block 320 and a locking rod 300. A fixed gap for accommodating a plurality of guide ropes 120 is formed between the locking rod 300 and the locking block 320. The locking rod 300 is movably arranged on the locking block 320 to adjust the distance of the fixed gap. In this way, through the change of the size of the fixed gap between the locking rod 300 and the locking block 320, a plurality of guide ropes 120 can be bundled and pressed.

[0044] Specifically, the locking rod 300 can be a U-shaped structure or a ring-shaped structure. Taking the ring-shaped structure as an example, locking holes 321 are opened at the front and rear ends inside the locking block 320, and the locking rod 300 is correspondingly movably arranged inside. A communication hole is vertically opened at the upper end of the locking hole 321, and a plug rod 340 is elastically arranged in the communication hole. Under the elastic action of the elastic member 350, the plug rod 340 is always pressed against the surface of the locking rod 300, thereby restricting the relative movement of the locking rod 300 with respect to the locking block 320. A pull rod 330 is provided at the upper end of the plug rod 340. When the locking rod 300 needs to move in the locking hole 321, the plug rod 340 can be pulled upward through the pull rod 330, so that the pressing state between the plug rod 340 and the locking rod 300 is released. At this time, the size of the fixed gap can be adjusted to facilitate the entry of the guide rope 120 or the pressing of the guide rope 120 in the fixed gap.

[0045] In this embodiment, taking the elastic member 350 as a tension spring as an example, the tension spring is sleeved outside the insertion rod 340. The upper end of the tension spring is connected to the bottom of the pull rod 330, and the lower end of the tension spring is connected to the upper end surface of the lock block 320. In this way, under the action of the tension spring, the insertion rod 340 always maintains a pressing state on the lock rod 300.

[0046] Furthermore, in order to increase the pressing force of the insertion rod 340 on the lock rod 300, referring to Figure 5 , a groove 310 can be formed on the surface of the lock rod 300 to increase the contact friction between the lock rod 300 and the insertion rod 340 by using the groove 310.

[0047] Of course, it can be conceived that as long as the contact friction between the insertion rod 340 and the lock rod 300 can be increased, the groove 310 can also be a number of protrusions or other structures, which will not be elaborated here again.

[0048] Based on the above embodiments, the box body 100 includes a waterproof outer layer, an inner layer and a heat insulation layer provided therebetween, a waterproof outer layer and a lining. Materials such as commonly used waterproof non-woven fabrics and Oxford cloth can be used. The heat insulation layer can be made of tin foil, aluminum foil or other materials. Since they are commonly used materials, they will not be elaborated here.

[0049] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various changes and modifications can be made to the present invention for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
