Description
Technical Field
[0001] The present application relates to the technical field of backpacks, and in particular to a waterproof backpack for snowboards. Background Art
[0002] Backpack refers to the general term for the bag carried on the back when going out or marching. The materials are diverse, and the styles of bags have also expanded from traditional business bags, school bags, and travel bags to pencil cases, coin purses, small sachets, etc. The snowboard backpack is a type of backpack.
[0003] Since ski backpacks are large in size, when users use them on rainy days, the umbrella may not be able to completely cover the ski backpacks, leaving them exposed to the rain. To reduce the amount of rainwater that seeps into the backpacks, existing ski backpacks are usually made of waterproof fabrics. However, there is a gap when the zipper is closed, and rainwater may seep into the backpacks through the gap, thus affecting the waterproof effect of the backpacks. Utility Model Content

[0032] The following is combined with Figure 1-6 This application is described in further detail.
[0033] Embodiment 1:
[0034] The embodiment of the present application discloses a waterproof backpack for a snowboard.
[0035] Reference Figure 1 A waterproof backpack for snowboards includes a backpack body 1, which is made of waterproof fabric. The backpack body 1 made of this material has good waterproof performance and reduces the situation where snow or rain water penetrates into the backpack body 1.
[0036] Reference Figure 2 The backpack body 1 has a storage space 11 for storing skis, and the backpack body 1 is provided with an opening 12 connected to the storage space 11; the backpack body 1 is sewn with a first zipper 13, and the first zipper 13 is used to open and close the opening 12 to put the skis into / take them out of the storage space 11.
[0037] A first magnetic sheet 2 and a second magnetic sheet 3 are sewn on the surface of the backpack body 1, and the first magnetic sheet 2 and the second magnetic sheet 3 are respectively located on opposite sides of the opening 12; an integrally formed plug-in block 21 is provided on one side of the first magnetic sheet 2 close to the second magnetic sheet 3, and the plug-in block 21 is located at one end of the first magnetic sheet 2 close to the zipper; the second magnetic sheet 3 is provided with a plug-in slot 31 for the plug-in block 21 to be plugged in.
[0038] Reference Figure 2 and Figure 3 A reinforcement strip 22 is provided on the surface of the first magnetic sheet 2, and the reinforcement strip 22 is rotatably installed on the first magnetic sheet 2 through a rotating shaft 23; the reinforcement strip 22 is made of rubber material, and a reinforcement block is integrally formed at one end of the reinforcement strip 22 away from the first magnetic sheet 2; a reinforcement groove 32 is provided on the surface of the second magnetic sheet 3 for the reinforcement block to be inserted, and the outer diameter of the reinforcement block is larger than the inner diameter of the reinforcement groove 32.
[0039] The reinforcement block is inserted into the reinforcement groove 32 by interference fit, which can increase the connection between the first magnetic sheet 2 and the second magnetic sheet 3, reduce the separation of the first magnetic sheet 2 and the second magnetic sheet 3 during the transportation of the backpack body 1, and further improve the waterproof effect of the backpack body 1.
[0040] The surface of the backpack body 1 is sewn with a first storage bag 14 and at least one second storage bag 15, and all the second storage bags 15 are located above the first storage bag 14; the first storage bag 14 and the second storage bag 15 are both provided with a second zipper 16, and the number of items that can be stored in the backpack body 1 can be increased by providing the first storage bag 14 and the second storage bag 15. In this embodiment, the first storage bag 14 and the second storage bag 15 are both provided with a first magnetic sheet 2 and a second magnetic sheet 3, further reducing the situation where rainwater enters the first storage bag 14 / the second storage bag 15 through the second zipper 16.
[0041] In this embodiment, four lifting straps 4 are sewn on the side of the backpack body 1, and rubber blocks 41 are provided on the side where two lifting straps 4 are close to each other. When the backpack body 1 is moved, the user holds the two rubber blocks 41 with both hands to apply force to the backpack body 1 to carry it, thereby reducing the possibility of the user pulling the lifting straps 4 and causing hand injuries.
[0042] Reference Figure 4 The back of the backpack body 1 is provided with a sponge pad 5, and the side of the sponge pad 5 away from the backpack body 1 is set as a wave surface. The sponge pad 5 is in direct contact with the back of the user. Since the sponge pad 5 has gaps, the air permeability between the back of the user and the backpack body 1 can be increased, so as to improve the comfort of the user wearing the backpack body 1.
[0043] The implementation principle of Example 1 of the present application is:
[0044] When the first zipper 13 is used to close the opening 12, the first magnetic sheet 2 and the second magnetic sheet 3 are close to each other and connected by magnetic force, and the plug-in block 21 is plugged into the plug-in slot 31; at this time, the first magnetic sheet 2 and the second magnetic sheet 3 cover the surface of the zipper, thereby reducing the situation where rainwater penetrates into the backpack through the gap of the zipper. In addition, the plug-in cooperation between the plug-in block 21 and the plug-in slot 31 can increase the contact area between the first magnetic sheet 2 and the second magnetic sheet 3, improve the sealing effect of the first magnetic sheet 2 and the second magnetic sheet 3, and further improve the waterproof effect of the backpack body 1.
[0045] Embodiment 2:
[0046] The embodiment of the present application discloses a waterproof backpack for a snowboard.
[0047] Reference Figure 5 and Figure 6 The difference between the embodiment 2 of the present application and the embodiment 1 is that the interior of the first storage bag 14 and the storage space 11 are connected through the installation port 17, and the first storage bag 14 is installed with two rubber sheets 18, and there is a gap between the two rubber sheets 18. An airbag 6 is provided at the bottom of the storage space 11, and an inflatable member 62 is installed in the first storage bag 14. The inflatable member 62 is connected to the airbag 6 through a connecting pipe, and the inflatable member 62 is used to communicate with an external inflatable device to inflate / deflate the airbag 6; because the two rubber sheets 18 are elastic, it is convenient to draw the airbag 6 from the storage space 11 into the first storage bag 14 in a deflated state.
[0048] The implementation principle of Example 2 of the present application is:
[0049] By inflating the interior of the airbag 6 through the inflatable member 62, the volume of the storage space 11 can be changed, so that the backpack body 1 can accommodate skis of different lengths, thereby reducing the possibility of the skis shaking freely in the backpack body 1; when the airbag 6 is not in use, the airbag 6 is stored in the first storage bag 14, and the obstruction of the two rubber sheets 18 can reduce the situation where the airbag 6 re-enters the storage space 11; the possibility of damage to the airbag 6 in the backpack body 1 is reduced, and the service life of the airbag 6 is increased.
[0050] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
