Description

Technical Field

[0001] The invention relates to the field of briefcases, and in particular to an anti-theft briefcase which is easy to carry. Background Art

[0002] Briefcases are mainly used to store and collect some official supplies, such as documents, tablets, books or certificates, etc. At present, the traditional briefcase has a simple structure and a limited storage space inside the briefcase. When the number of storage items is large, the limited space can only accommodate limited items. If the documents are forced into the briefcase, the briefcase is easily broken. In addition, the traditional briefcase lacks a protective structure. When placed, it is easy to rub against the supporting platform, causing wear on the surface of the briefcase, resulting in peeling of the briefcase, resulting in poor appearance and waterproof effect, and poor practicality. At the same time, the traditional briefcase has simple functions and can only perform a single storage function. When the user carries the briefcase when going out, if there is an emergency, such as raining and the user does not have an umbrella, it cannot provide the user with rain protection, and the functionality is poor. Summary of the invention

[0003] The purpose of the invention is to provide a theft-proof briefcase which is easy to carry and has the advantages of strong practicability and multi-function.

[0004] The above technical purpose of the present invention is achieved through the following technical scheme: it includes a bag body, a cover is arranged on the front of the bag body, a pleated outer periphery is sewn between the cover and the bag body, a connecting piece is bonded to the back of the bag body, a cover surface is installed on the connecting piece through a fixing part, connecting pleats are sewn on the cover surface, a bag cover is sewn on the connecting pleats, a connecting plate is clamped on the bottom of the bag cover, pads are bonded to the surface of the bag body and the surface of the bag cover, the material of the pads is wear-resistant rubber, a connecting block is bolted to the connecting piece, a telescopic support rod is bolted to the connecting block, a storage bag is sewn on the front of the cover, a round rainproof cloth is placed inside the storage bag, a clamping sleeve is bonded to the surface of the round rainproof cloth, and the clamping sleeve is used in conjunction with the telescopic support rod.

[0005] By adopting the above technical scheme, the present invention has a pleated outer periphery sewn on the front of the bag body, and a cover is sewn on the pleated outer periphery. Compared with the traditional briefcase, the pleated outer periphery of the present application can drive the cover away from the bag body, so that the storage space between the cover and the bag body becomes larger, and cooperates with the connecting pleats so that the bag cover and the connecting plate can be normally covered on the cover, and locked by using a lock buckle and a sealing lock to increase the storage capacity. At the same time, with the use of a cushion block, the surface of the bag body can be protected so that when it is placed, the supporting platform cannot contact the surface of the briefcase to prevent it from being worn and peeling, thereby improving practicality. By installing a connecting piece on the back of the bag body, a connecting block on the connecting piece, and a telescopic support rod on the connecting block, when it rains suddenly and the user does not bring an umbrella, the circular rainproof cloth stored in the storage bag can be taken out and opened, and the telescopic support rod can be extended so that one end of the telescopic support rod is inserted into the card sleeve of the circular rainproof cloth to form an umbrella structure, which can protect the user from rain and improve functionality.

[0006] The present invention is further configured as follows: a lock buckle and a password lock that cooperate with each other are bolted to the connecting plate and the front side of the cover respectively.

[0007] The above technical solution is adopted to facilitate the briefcase to be locked to prevent theft.

[0008] The present invention is further configured as follows: a partition bag is sewn inside the bag body, and the partition bag divides the bag body into two independent cavities.

[0009] By adopting the above technical solution, it is convenient to divide the interior of the bag into two independent cavities for classifying and placing items.

[0010] The present invention is further configured as follows: locking tooth rows are symmetrically sewn on the top of the package body, and a locking tooth head is slidably connected between two locking tooth rows.

[0011] The above technical solution is adopted to facilitate closing the opening of the bag body.

[0012] The present invention is further configured as follows: the bag body, the cover, the outer periphery of the pleats, the cover surface, and the material connecting the pleats and the bag cover are all made of artificial leather.

[0013] The above technical solution is adopted to improve the waterproof performance and reduce the cost.

[0014] The present invention is further configured as follows: a limiting belt is symmetrically installed on the surface of the package body through a fixing piece, a limiting seat which is sleeved with the limiting belt is symmetrically bonded to the surface of the cover, and a limiting bolt which is used in conjunction with the limiting belt is threadedly connected to the front of the limiting seat.

[0015] The above technical solution is adopted to facilitate limiting the distance between the cover and the package body.

[0016] The present invention is further configured as follows: a shoulder strap is sewn on the surface of the bag body, a hand strap is sewn on the surface of the cover, and protective covers are fixedly sleeved on the surfaces of the shoulder strap and the hand strap.

[0017] The adoption of the technical solution makes it convenient for the user to carry the briefcase.

[0018] The present invention is further configured as follows: a rubber pad is bonded to the side of the connecting piece away from the bag body, and the rubber pad is used in conjunction with the telescopic support rod.

[0019] The above technical solution is adopted to prevent the connecting piece from causing friction to the user.

[0020] The invention is further configured as follows: the surface of the telescopic support rod is threadedly connected to a limit bolt.

[0021] By adopting the above technical solution, the telescopic length of the telescopic support rod is limited.

[0022] The invention is further configured as follows: a storage interlayer is sewn on the front side of the cover, and the storage interlayer is used in conjunction with postcards.

[0023] The above technical solution is adopted to facilitate users to store their postcards.

[0024] In summary, the present invention has the following beneficial effects: 1. The present invention has a pleated outer periphery sewn on the front of the bag body, and a cover sewn on the pleated outer periphery. Compared with the traditional briefcase, the pleated outer periphery of the present application can drive the cover away from the bag body, so that the storage space between the cover and the bag body becomes larger, and the pleated outer periphery is connected so that the bag cover and the connecting plate can be normally covered on the cover, and the buckle and the sealing lock are used to lock it, thereby increasing the storage capacity. At the same time, the surface of the bag body can be protected by the use of a cushion block, so that when it is placed, the support platform cannot contact the surface of the briefcase, preventing it from being worn and peeling, thereby improving practicality; 2. The present invention has a connecting piece installed on the back of the bag body, a connecting block installed on the connecting piece, and a telescopic support rod installed on the connecting block. When it rains suddenly and the user does not bring an umbrella, the user can take out the circular rainproof cloth stored in the storage bag and open it, extend the telescopic support rod, and insert one end of the telescopic support rod into the card sleeve of the circular rainproof cloth to form an umbrella structure, thereby protecting the user from rain and improving functionality.
