Description

Anti-theft and anti-dirt device for backpack

Technical Field

The utility model relates to a knapsack technical field, more specifically relates to a dirty device is prevented in knapsack theftproof.

Background

With the continuous development of economy, the living standard of people is increasingly improved, the tendency of carrying the backpack when going out is realized, and various backpacks become indispensable ornaments beside people. However, when people use the backpack, the user often encounters a situation that the schoolbag is placed on the ground, and at the moment, the bottom of the backpack directly contacts the ground, so that the backpack is easily soiled (wetted), and the backpack needs to be cleaned, but the backpack is relatively troublesome to clean. And sometimes the articles are lost, and the backpack owner is very helpless in the face of the situations. For people who often use the backpack, the backpack anti-fouling device can effectively prevent the backpack from becoming dirty and reduce the cleaning of the backpack; the anti-theft backpack can ensure that the articles cannot be lost. In recent years, many researchers at home and abroad research and develop different backpack anti-fouling devices and anti-theft devices, so that the backpack is anti-fouling and anti-theft, but the anti-fouling effect of the anti-fouling device is poor, and the anti-theft backpack cannot be well combined with other functional backpacks. Therefore, the device which has the functions of dirt prevention and theft prevention, is comfortable, light, simple and convenient to carry, simple to operate and fashionable has an important application market.

The current mainstream backpack anti-fouling devices comprise a pull rod type anti-fouling device, a bagging type anti-fouling device and a supporting type anti-fouling device; the anti-theft device is provided with a zipper for locking, a concealed anti-theft backpack, and anti-theft by using new materials. The pull rod type anti-fouling device mainly comprises a pull rod seat, a sleeve fixed on the pull rod seat and a telescopic pull rod, so that the backpack is pulled away from the ground by a certain distance, the anti-fouling of the backpack is realized, and the shoulders can be released; the bag-sleeving type anti-fouling device is characterized in that a bag-shaped object is sleeved at the bottom of the backpack, so that the bottom of the backpack is prevented from being directly contacted with the ground, and the anti-fouling of the backpack is realized; the supporting type anti-dirty device is characterized in that a plurality of vertical legs are arranged at the bottom of the backpack, so that when the backpack is contacted with the ground, the vertical legs can be directly contacted with the ground, and the backpack is separated from the ground, so that the purpose of preventing the backpack from being dirty is achieved; a zipper-locking type anti-theft backpack is mainly characterized in that a coded lock or a mechanical lock is added to a zipper, so that the protection level of the backpack is improved; the hidden anti-theft backpack mainly hides the entrance of partial bags in the backpack in a less striking position, thereby increasing the safety factor of the backpack; the anti-theft backpack made of the new material has good quality, and can reduce the loss of backpack articles.

The existing backpack anti-fouling and anti-theft device has various forms, but no backpack capable of combining two functions is available, and the anti-fouling effect is not good. The roller of the pull rod type anti-fouling device may contact with the back of a user to foul the back of the user, and the pull rod type anti-fouling device is too large in size and not easy to carry; the anti-dirty bag of the bagging type anti-dirty device is easy to be dirty, and the anti-dirty bag is frequently replaced and cleaned when needed, which is also troublesome; the supporting height of the supporting type anti-fouling device is fixed and unchanged, the device cannot adapt to special occasions (sections with deep rainwater, sections with uneven ground height and the like), and the anti-fouling effect is poor; the backpack with the locked zipper has an anti-theft function, but has a poor attractive appearance, more operation steps and inconvenience in use; the hidden anti-theft backpack has an unobvious anti-theft effect and a single function; the anti-theft backpack made of the new material has the anti-theft effect but is expensive. Currently, a backpack device which is anti-theft and anti-dirty is absent in the market.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's not enough, provide a dirty device is prevented in knapsack theftproof, can keep apart knapsack and ground, realize preventing dirty, and have the theftproof package, can place valuables, realize the theftproof.
