DETAILED DESCRIPTION
[0022] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.
[0023] Please refer to Figures 1-6 The pull-to-bottom anti-theft backpack of the present application includes a backpack body 100 and a zipper assembly 200.
[0024] The front of the backpack body 100 is provided with a backpack opening 11 extending upward and downward. The zipper assembly 200 includes a zipper 210, a puller 220 and a pull tail 230. The zipper 210 is arranged corresponding to the backpack opening 11 and the upper end of the zipper 210 extends to the side where the back of the backpack body 100 is located through the top end of the backpack body 100. The puller 220 is arranged at the upper end of the zipper 210. The pull tail 230 is movably connected to the puller 220 and is used for being pinched by a hand to pull the puller 220 to move along the zipper 210.
[0025] The puller 220 is configured to move along the zipper 210 to the lower end of the zipper 210 to open the backpack opening 11. The pull tail 230 is provided with a first connecting structure 250, and the upper end of the backpack body 100 is provided with a second connecting structure 260 located at the side where the back of the backpack body 100 is located. The first connecting structure 250 is detachably connected with the second connecting structure 260.
[0026] In the above manner, when the pull-to-bottom anti-theft backpack 10 is worn on the back of a user, the gap between the back of the user and the side where the back of the backpack body 100 is located is small, so that the anti-theft performance can be improved at least in the following two aspects. First, since the upper end of the zipper 210 extends to the side where the back of the backpack body 100 is located through the top of the backpack body 100, it is not easy for outsiders to find and pull the puller 220. Second, since the puller 220 is connected to the side where the back of the backpack body 100 is located through the detachable connection of the first connecting structure 250 and the second connecting structure 260, and it is not easy for outsiders to stretch into the gap between the back of the backpack body 100 and the back of the user, so the first connecting structure 250 and the second connecting structure 260 are not easy to be separated by outsiders. It should be noted that the user is a person who uses the backpack, and the outsider is a person other than the user.
[0027] Optionally, as shown in Figures 1-6 The pull-to-bottom anti-theft backpack includes an upper extension body 300, and the lower end of the upper extension body 300 is connected with the upper end of the backpack body 100. The zipper 210 is arranged corresponding to the backpack opening 11 and extends to the upper end of the upper extension body 300. The upper end of the upper extension body 300 extends to the side where the back of the backpack body 100 is located, so that the upper end of the zipper 210 extends to the side where the back of the backpack body 100 is located through the upper end of the backpack body 100. In this way, the upper end of the zipper 210 can be more conveniently extended to the side where the back of the backpack body 100 is located.
[0028] Optionally, as shown in Figures 1-6 The upper extension body 300 is gradually contracted from the lower end of the upper extension body 300 to the upper end of the upper extension body 300. In this way, the upper end of the upper extension body 300 is smaller than the lower end of the upper extension body 300, forming a small end, which is convenient for a hand to hold the upper end of the upper extension body 300.
[0029] Optionally, as shown in FIG. 3, the upper extension cavity 301 is provided in the upper extension body 300, and the backpack cavity 101 is provided in the backpack body 100. The upper extension cavity 301 is in communication with the backpack cavity 101 and extends to the upper end of the upper extension body 300. The backpack opening 11 is in communication with the backpack cavity 101, and the backpack opening 11 extends to the upper end of the upper extension body 300 and is in communication with the upper extension cavity 301. Figures 1-6
[0030] In this way, the upper extension cavity 301 can also be used to accommodate objects when needed. When the upper extension cavity 301 does not accommodate objects, i.e., the upper extension cavity 301 is empty, the upper extension cavity 301 is retracted to make the upper extension body 300 flat.
[0031] Optionally, as shown in FIG. 3, the first connecting structure 250 and the second connecting structure 260 are magnetically attracted. In this way, when the bottom-pulling theft-proof backpack 10 is removed from the user's back, the user can more conveniently separate the first connecting structure 250 and the second connecting structure 260. Figures 1-6
[0032] Optionally, as shown in FIG. 3, the first connecting structure 250 includes a protruding buckle 251. The second connecting structure 260 includes a base 261 and a clamping block 262. Figures 1-6
[0033] The base 261 is provided with a sliding groove 263. The sliding groove 263 extends from the lower edge of the base 261 to the inner side of the base 261, and the sliding groove 263 is in communication with the lower edge of the base 261 and the side of the base 261 away from the backpack body 100. The clamping block 262 is protrudingly arranged at the edge of the sliding groove 263. The protruding buckle 251 is arranged in the sliding groove 263 and is clamped and blocked with the clamping block 262 to prevent the protruding buckle 251 from being separated from the sliding groove 263 at the end away from the lower edge of the base 261; the protruding buckle 251 can slide downward along the sliding groove 263 to be separated from the sliding groove 263.
[0034] In this way, as shown in FIG. 3, the first connecting structure 250 and the second connecting structure 260 are magnetically attracted. In this way, when the bottom-pulling theft-proof backpack 10 is removed from the user's back, the user can more conveniently separate the first connecting structure 250 and the second connecting structure 260. Figures 1-6 As shown, the convex buckle 251 needs to slide downward to be separated from the sliding groove 263, so that the first connecting structure 250 and the second connecting structure 260 are separated, and then the puller 220 is pulled to move the puller 220 along the zipper 210 to the lower end of the zipper 210, so that the backpack opening 11 can be pulled open. When the convex buckle 251 is located in the sliding groove 263, the convex buckle 251 is limited by the blocking block 262, which can prevent the convex buckle 251 from being separated from the sliding groove 263 away from one end of the lower edge of the base 261. Therefore, the convex buckle 251 and the blocking block 262 are blocked and matched to limit the position of the puller 220, so that the puller 220 is not easy to move along the zipper 210 to the lower end of the zipper 210 under the action of the force on both sides of the backpack opening 11. Therefore, the convex buckle 251 and the blocking block 262 are blocked and matched to prevent the backpack opening 11 from being pulled open by the puller 220.
[0035] Optionally, as shown in Figures 1-6 , the sliding groove 263 has a first groove section 2631 close to the lower edge of the base 261 and a second groove section 2632 away from the lower edge of the base 261. Among them, the blocking block 262 avoids the first groove section 2631 and is arranged corresponding to the second groove section 2632.
[0036] In the above manner, the first groove section 2631 guides the convex buckle 251 to slide into the second groove section 2632 or slide out from the lower edge of the base 261. The convex buckle 251 slides into the second groove section 2632 to block and match the convex buckle 251 with the blocking block 262, and the convex buckle 251 slides out from the lower edge of the base 261 to separate the first connecting structure 250 from the second connecting structure 260. It should be noted that the convex buckle 251 can also be separated from the second sliding groove 263 from the side of the backpack body 100 away from the second sliding groove 263.
[0037] Optionally, as shown in Figures 1-6 , the pull tail 230 is flat, and the zipper assembly 200 comprises a connecting piece 240. The connecting piece 240 is provided with an avoiding opening 241. The part of the connecting piece 240 located below the avoiding opening 241 is connected with the pull tail 230. The part of the connecting piece 240 located above the avoiding opening 241 is movably arranged in the puller 220. It should be noted that the pull tail 230 is not limited to be flat, and in other examples, the pull tail 230 can be cylindrical, long strip-shaped, chain-shaped or rope-shaped.
[0038] Optionally, in combination with Figures 1-3 , as shown in Figures 7-8 , the anti-theft backpack 10 comprises a zipper cover 400, which is arranged corresponding to the zipper 210 to cover the zipper 210 and the puller 220. One side of the zipper cover 400 can be lifted to expose the zipper 210 and the puller 220.
[0039] By the above manner, covering the zipper 210 and the slider 220 by the zipper cover 400 can hide the zipper 210 and the slider 220, so that the position of the zipper 210 and the slider 220 is not easy to be found by outsiders, and the anti-theft performance of the anti-theft backpack 10 is further enhanced.
[0040] As shown in Figures 1-3 , the left side and / or the right side of the backpack body 100 is provided with a slit-shaped opening 102, and the slit-shaped opening 102 is in communication with the backpack cavity 101. The slit-shaped opening 102 extends into a slit shape along the up-down direction. When the slit-shaped opening 102 is squeezed by external force on both sides of the slit-shaped opening 102, the slit-shaped opening 102 is opened to allow the hand to extend into the backpack cavity 101, and when the external force on both sides of the slit-shaped opening 102 is lost, the slit-shaped opening 102 is closed. The length of the slit-shaped opening 102 when closed can be smaller than the length of the backpack opening 11 when pulled open.
[0041] It should be noted that the slit-shaped opening 102 can be configured to be adapted to the size of the human hand, so as to facilitate the hand to extend into the backpack cavity 101 when the slit-shaped opening 102 is opened, so as to access the first article. The first article includes but is not limited to small and / or inexpensive articles, such as at least one of a notebook, an eraser, a pen, and coins. The backpack opening 11 can be configured to be larger than the human hand, so as to facilitate the hand to extend into the backpack cavity 101 when the backpack opening 11 is pulled open, so as to access the second article. The second article includes but is not limited to large and / or expensive articles, such as at least one of a notebook computer, a tablet computer, and a bank card.
[0042] By the above manner, when the external force on both sides of the slit-shaped opening 102 is lost, the slit-shaped opening 102 is closed, and it is not easy for outsiders to find the slit-shaped opening 102, and even if outsiders find and extend into the backpack cavity 101 through the slit-shaped opening 102, it is difficult to take large articles from the backpack cavity 101 through the slit-shaped opening 102.
[0043] Optionally, a storage bag is arranged in the backpack cavity 101 at the left side and / or the right side of the backpack cavity 101, and at least part of the slit-shaped opening is located above the bag opening of the storage bag, so that the hand extending into the backpack cavity 101 from the slit-shaped opening 102 can extend into the storage bag to access the first article. The first article includes but is not limited to small and / or inexpensive articles, such as at least one of a notebook, an eraser, a pen, and coins.
[0044] Optionally, in combination with Figures 1-3 , referring to Figure 9 , a computer compartment 103 is formed in the backpack cavity 101 at the side of the backpack cavity 101 close to the back of the backpack body 100. The computer compartment 103 is formed with a computer compartment back panel 1031 at the side close to the back of the backpack body 100, and is formed with a computer compartment front panel 1032 at the side close to the front of the backpack body 100.
[0045] The rear panel 1031 of the computer compartment is connected to a computer compartment cover 1033, one end of which is fixed to the rear panel 1031 corresponding to the computer compartment 103. The computer compartment cover 1033 is magnetically attached to the front panel 1032 of the computer compartment to prevent the computer inside the computer compartment 103 from being accessed. Under external force, the computer compartment cover 1033 can be flipped away from the front panel 1032 to detach from it.
[0046] In this manner, when the computer compartment cover 1033 is magnetically attached to the front cover of the computer compartment 103, the computer compartment cover 1033 stops the computer inside the computer compartment 103, preventing the computer from falling out of the computer compartment 103. By manually flipping the computer compartment cover 1033 away from the front cover 1032 of the computer compartment, the computer compartment cover 1033 is detached from the front cover 1032 of the computer compartment, and then the computer can be removed from the computer compartment 103 by hand.
[0047] Optionally, combined Figures 1-3 See Figure 9 As shown, a document pocket 104 is provided on the side of the front panel 1032 of the computer compartment near the front of the backpack body 100. The document pocket 104 has two side-by-side reserved pockets 105 on the side of the front of the backpack body 100. The document pocket 104 can hold documents, and the reserved pockets 105 can hold small items.
[0048] Optionally, combined Figures 1-3 See Figure 9 As shown, a document pocket 104 has a front panel 1041 formed on the side of the front of the backpack body 100. The front panel 1041 is sewn to the front panel 1032 of the computer compartment to form a document pocket 104. Two left-right arranged reserve pockets 105 have front panels 1051 formed on the side of the front of the backpack body 100. The front panels 1051 are sewn to the front panel 1041 of the document pocket to form two left-right arranged reserve pockets 105.
[0049] Optionally, combined Figures 1-3 See Figure 9 As shown, the openings of the computer compartment 103, the document bag 104, and the reserve bag 105 are all located above the seam opening 102, to increase the difficulty for a person to reach into the computer compartment 103, document bag 104, and reserve bag 105 from the seam opening 102 into the backpack cavity 101.
[0050] Optionally, combined Figures 1-3 See Figures 7-8 As shown, pull the anti-theft backpack to the bottom. The first shoulder strap is 500mm, the second shoulder strap is 600mm, and the limiting strap is 700mm.
[0051] The first shoulder strap 500 is arranged on the back of the backpack body 100 at one side of the opening seam and is used to cooperate with the left shoulder of the human body. The second shoulder strap 600 is arranged on the back of the backpack body 100 at the other side of the opening seam and is used to cooperate with the right shoulder of the human body. The limiting strap 700 is connected with the first shoulder strap 500 and the second shoulder strap 600 respectively and is used to cooperate with the front of the chest of the human body and to limit the distance between the first shoulder strap 500 and the second shoulder strap 600.
[0052] In the above manner, the configuration of the limiting strap 700 can prevent the first shoulder strap 500 from slipping off the left shoulder of the human body and can prevent the second shoulder strap 600 from slipping off the right shoulder of the human body.
