Description

Technical Field

[0001] The utility model relates to the technical field of waterproof zippers, in particular to a highly waterproof zipper structure. Background Art

[0002] A zipper is a fastener consisting of two strips, each with a row of metal or plastic teeth, used to connect the edges of an opening (such as the opening of a garment or bag). A sliding piece can pull the two rows of teeth into an interlocking position to close the opening. It is used to be sewn on clothing, pockets, purses, etc.

[0003] Currently, common zippers not only need to have the effect of closing the opening, but also need to maintain a certain degree of sealing and waterproofness under certain circumstances, such as when camping in a tent outdoors. However, the current common zippers have a low degree of waterproofness. Since there is a certain interval between the meshing sprockets on both sides, a certain degree of sealing can be guaranteed in a short period of rain. However, when it rains for a long time, when the rain flows along the outer wall of the tent, it will penetrate into the tent through the gaps between the sprockets. Currently, some waterproof zippers have staggered waterproof membranes on the inside, but in the design of the tent, the zippers of the tent are all inside the tent, which is convenient for opening and closing the tent exit inside the tent. This results in the waterproof membrane originally set on the inside not having the original waterproof effect, making the zipper waterproofness of the tent relatively low.

[0004] Therefore, it is necessary to provide a new highly waterproof zipper structure to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a highly waterproof zipper structure which is easy to operate and can enhance waterproofness.

[0006] In order to solve the above technical problems, the utility model provides a highly waterproof zipper structure comprising: two polyester cloth layers, the surfaces of the two polyester cloth layers are connected to waterproof cloth layers, the two waterproof cloth layers are respectively connected to a first chain and a second chain, the first chain and the second chain are connected to a main zipper, a secondary zipper is movably installed on the top of the main zipper, and the two waterproof cloth layers are connected to waterproof layers.

[0007] Preferably, a sealing strip 1 and a sealing strip 2 are respectively connected to the sides of the two waterproof layers close to each other, the sealing strip 1 and the sealing strip 2 are meshed with each other, and the secondary zipper is slidably installed on the sealing strip 1 and the sealing strip 2.

[0008] Preferably, a connecting block is fixedly installed on the top of the main zipper, and retaining grooves are provided on the outer walls on both sides of the connecting block.

[0009] Preferably, two vertical plates are fixedly installed at the bottom of the secondary zipper, clamping plates are slidably installed on the two vertical plates, and protrusions are fixedly installed on the outer walls of the two clamping plates on one side close to each other, and the two protrusions extend into the two clamping grooves respectively.

[0010] Preferably, two limiting rods are fixedly installed between the two vertical plates, and the two limiting rods both penetrate the two clamping plates and are slidably connected thereto.

[0011] Preferably, springs are provided between the two vertical plates and the two clamping plates, and the ends of the two springs that are away from each other are fixedly connected to the outer walls of the two vertical plates that are close to each other, and the ends of the two springs that are close to each other are fixedly connected to the outer walls of the two clamping plates that are away from each other.

[0012] Compared with the related art, the highly waterproof zipper structure provided by the utility model has the following beneficial effects:

[0013] The utility model provides a zipper structure with high waterproofness. In the waterproof design of the camping tent, the meshed first chain and the second chain increase the tightness of the combination with each other through staggered teeth, but the gap between the teeth will also cause the penetration of rainwater, and the sealing strip 1 and the sealing strip 2 between the two waterproof layers are connected through concave and convex embedding. Although the tightness between them is low, a seamless connection between the two can be achieved, and the two complement each other, which not only ensures the tightness but also improves the waterproof performance, and the main zipper and the auxiliary zipper can be quickly combined and separated, so that the first chain, the second chain and the sealing strip 1 and the sealing strip 2 can be closed synchronously.

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1-Figure 6 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a highly waterproof zipper structure provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the tapping state of the main zipper and the first chain shown; Figure 3 for Figure 1 A schematic front plan view of the first chain and the second chain shown; Figure 4 for Figure 1 A schematic diagram of the top view of the main zipper shown;

[0023] Figure 5 for Figure 1 A schematic diagram of the structure of the secondary zipper as viewed from above; Figure 6 for Figure 1 The front view and partial enlarged view of the secondary zipper shown in the figure. The highly waterproof zipper structure comprises: two polyester fabric layers 1, the surfaces of the two polyester fabric layers 1 are connected to waterproof fabric layers 2, the two waterproof fabric layers 2 are respectively connected to a first chain 4 and a second chain 5, the first chain 4 and the second chain 5 are meshed with each other, and the first chain 4 and the second chain 5 are respectively sewn to the two waterproof fabric layers 2 through a connecting layer 3, the first chain 4 and the second chain 5 are connected to a main zipper 9, the top of the main zipper 9 is movably equipped with a secondary zipper 10, the two waterproof fabric layers 2 are connected to a waterproof layer 6, and the first chain 4 and the second chain 5 are respectively sewn to the two waterproof fabric layers 2 through a connecting layer 3. Figure 1 As shown, one side of the two waterproof layers 6 is sewn on the two waterproof cloth layers 2, and the two waterproof layers 6 are soft waterproof membranes.

[0024] The two waterproof layers 6 are connected to a sealing strip 1 7 and a sealing strip 2 8 on one side close to each other. The sealing strip 1 7 and the sealing strip 2 8 are meshed with each other. The sealing strip 1 7 and the sealing strip 2 8 are common sealing strips in the prior art. The secondary zipper 10 is slidably installed on the sealing strip 1 7 and the sealing strip 2 8. In actual use, the sealing strip 1 7 and the sealing strip 2 8 can be closed or opened by pulling the secondary zipper 10. When the sealing strip 1 7 and the sealing strip 2 8 are closed, the waterproof performance can be further improved.

[0025] A connecting block 11 is fixedly installed on the top of the main zipper 9, and a clamping groove 12 is provided on the outer walls of both sides of the connecting block 11. Figure 6 As shown, the two clamping grooves 12 are symmetrically opened based on the midpoint of the connecting block 11, and the edges of the top inner walls and the bottom inner walls of the two clamping grooves 12 are both set as semicircular arc surfaces.

[0026] Two vertical plates 13 are fixedly installed at the bottom of the secondary zipper 10, and a clamping plate 15 is slidably installed on the two vertical plates 13. Figure 5 As shown, the two vertical plates 13 are symmetrically arranged based on the midpoint of the secondary zipper 10, and the outer walls of the two clamping plates 15 on one side close to each other are fixedly mounted with protrusions 16, combined with Figure 6 As shown, the two protrusions 16 are respectively located at the bottom edge of the clamping plate 15 , and the protrusions 16 are semicircular cylinders. The two protrusions 16 extend into the two card holding grooves 12 respectively.

[0027] In order to make the two clamping plates 15 always maintain horizontal lateral movement and improve the accuracy of the protrusion 16 being embedded in the clamping groove 12, two limit rods 14 are fixedly installed between the two vertical plates 13. The two limit rods 14 both pass through the two clamping plates 15 and are slidably connected thereto. The two limit rods 14 are symmetrically arranged based on the midpoint of the vertical plates, and the two limit rods 14 are located near the top of the vertical plates.

[0028] In order to ensure that the two protrusions 16 are always embedded in the two clamping grooves 12 without being affected by external forces, thereby improving the stability of the clamping effect, springs 17 are provided between the two vertical plates 13 and the two clamping plates 15, and the ends of the two springs 17 that are away from each other are fixedly connected to the outer walls of the two vertical plates 13 that are close to each other, and the ends of the two springs 17 that are close to each other are fixedly connected to the outer walls of the two clamping plates 15 that are away from each other.

[0029] The working principle of the highly waterproof zipper structure provided by the utility model is as follows:

[0030] In the initial state, and when the wild camping tent is not raining, the main zipper 9 and the secondary zipper 10 are separated, the two waterproof layers 6 are separated and dragged on the two polyester cloth layers 1, and the sealing strips 1 7 and 2 8 at the bottom ends of the two waterproof layers 6 are connected together, and the secondary zipper 10 is attached to the position where the sealing strips 1 7 and 2 8 are connected. At this time, the staff can open or close the first chain 4 and the second chain 5 by pulling the main zipper 9 to open or close the opening of the tent.

[0031] When it rains, the staff can hold the secondary zipper 10, align the two clamping plates 15 on the secondary zipper 10 with the connecting block 11 on the main zipper 9 and press. During the pressing process, the two protrusions 16 will gradually contact the top of the connecting block 11. Under the effect of the pressing force, the two protrusions 16 will drive the two clamping plates 15 away from each other, thereby gradually compressing the two springs 17, and after the two protrusions 16 move away from each other to a certain distance, they will be sleeved on both sides of the connecting block 11. At this time, under the resetting effect of the two springs 17, the two clamping plates 15 approach each other, so that the two protrusions 16 enter the two clamping grooves 12 respectively, and the main zipper 9 and the secondary zipper 10 will overlap together. At this time, when the secondary zipper 10 is pulled upward inside the tent, the main zipper 9 will also be pulled upward, so that when the secondary zipper 10 brings the sealing strip 1 7 and the sealing strip 2 8 together, the main zipper 9 will also gather and mesh the first chain 4 and the second chain 5 together.

[0032] In this way, the opening of the tent can be quickly closed, and at the same time, the two waterproof layers 6 are meshed together to form a Figure 1 The arc-shaped waterproof layer shown in the figure, and the rainwater that penetrates through the gap between the teeth of the first chain 4 and the second chain 5 will drip on the two waterproof layers 6, and will flow downward along the two inclined waterproof layers 6 (the outer wall of the tent is mostly in an inclined state, so the two waterproof layers 6 that fit the inner wall of the tent also present a corresponding inclined angle), and finally flow to a position close to the ground. The user only needs to place a simple container at the opening below the two waterproof layers 6 to prevent the rain from wetting the inside of the tent.

[0033] Compared with the related art, the highly waterproof zipper structure provided by the utility model has the following beneficial effects:

[0034] The utility model provides a zipper structure with high waterproofness. In the waterproof design of the camping tent, the meshed first chain 4 and the second chain 5 increase the tightness of the combination with each other through staggered teeth, but the gap between the teeth will also cause the penetration of rainwater, and the sealing strip 1 7 and the sealing strip 2 8 between the two waterproof layers 6 are connected by concave and convex embedding. Although the tightness between them is low, a seamless connection between the two can be achieved, and the two complement each other, which not only ensures the tightness but also improves the waterproof performance. In addition, the main zipper 9 and the auxiliary zipper 10 can be quickly combined and separated, so that the first chain 4, the second chain 5 and the sealing strip 1 7 and the sealing strip 2 8 can be closed synchronously.
