Abstract
Description
Technical Field
[0001] This utility model relates to the field of stationery bag technology, and more specifically to a stationery bag that indicates whether it has been opened. Background Technology
[0002] Similar stationery bags in the prior art have been disclosed in the following patent documents.
[0003] Chinese utility model patent specification CN 202552593 U (published on November 28, 2012) discloses a pencil case. The pencil case includes a main body with a zipper at the top and a suction cup attached to one side. This utility model utilizes the suction cup to facilitate primary and secondary school students in attaching the pencil case to their desks or bookends, preventing it from falling to the ground and making it easier for them to access their stationery.
[0004] However, if the pencil case disclosed above is opened by someone else at school or at home, the owner of the pencil case will not know. Therefore, this will make the owner of the pencil case feel insecure and often worry that their personal privacy (such as diary) inside the pencil case will be spied on by others without their knowledge. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a stationery bag that can indicate whether it has been opened, so as to overcome the defect of the prior art that if a stationery bag is opened by someone else, the owner of the stationery bag cannot know.
[0006] To solve the above-mentioned technical problems, the present invention provides a stationery bag that can detect whether it has been opened, comprising a stationery bag body and a zipper for closing the opening of the stationery bag body, the zipper having a zipper head; it also includes a lock body disposed on the stationery bag body, and a locking tongue inserted into the lock body; the lock body includes a base, the base having a protrusion, the square opening of the zipper head being able to be accommodated on the protrusion, the protrusion having a locking tongue opening, and the inner side of the locking tongue opening having a protrusion; the locking tongue includes a concave plastic plate and a separate plastic block connected to the concave plastic plate, the separate plastic block being unable to pass through the locking tongue opening, and the concave plastic plate having an elastic oblique piece.
[0007] The concave plastic plate has friction strips at its lower part.
[0008] The concave plastic plate has markings on it.
[0009] A piece of fabric is attached to the zipper.
[0010] The lock body is located on the cloth block.
[0011] This utility model discloses a stationery bag that can be identified as open or closed, comprising a stationery bag body and a zipper for closing the opening of the stationery bag body, the zipper having a zipper head; it also includes a lock body disposed on the stationery bag body, and a locking tongue inserted into the lock body; the lock body includes a base, on which a first protrusion and a second protrusion are disposed opposite each other, the square opening of the zipper head being able to be accommodated on the first protrusion, the first protrusion or the second protrusion having a locking tongue opening, the inner side of the locking tongue opening having a protrusion; the locking tongue includes a concave plastic plate and a separate plastic block connected to the concave plastic plate, the separate plastic block being unable to pass through the locking tongue opening, the concave plastic plate having a first elastic inclined plate and a second elastic inclined plate.
[0012] The concave plastic plate has friction strips at its lower part.
[0013] The concave plastic plate has markings on it.
[0014] A piece of fabric is attached to the zipper.
[0015] The lock body is located on the cloth block.
[0016] Compared with existing technologies, the advantages of this utility model are its simple structure. To open the pencil case, one must first use scissors to cut the plastic blocks and then pull down the disposable locking latch. If the pencil case is opened by someone else, the owner of the pencil case will know. Attached Figure Description

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0023] The stationery bag in this embodiment is like... Figures 1-5As shown, the pencil case includes a body 1 made of fabric, a zipper 2 at the opening of the body for closing, and a zipper pull 3. A fabric piece 4 extends from the zipper, and a plastic lock body 5 has a fixing hole 20. The plastic lock body and the fabric piece are fixed together by a pin passing through the fixing hole. A latch 6 is inserted into the lock body. The lock body includes a base 7, on which a first protrusion 8 and a second protrusion 9 are arranged opposite each other. When the opening is closed, the square opening 10 of the zipper pull can be accommodated on the first protrusion. Both the first and second protrusions have a latch opening 11, and the bottom of the latch opening has a spherical protrusion 12. The latch includes a concave plastic plate 13 and a separate plastic block 14 connected to the concave plastic plate. The volume of the separate plastic block is larger than the latch opening, so the separate plastic block cannot pass through the latch opening. The concave plastic plate has a first elastic inclined plate 15 and a second elastic inclined plate 16. A friction strip 17 is provided at the bottom of the concave plastic plate to facilitate the user to pull the latch downward. When the latch is pulled down, the separating plastic block cannot pass through the latch opening, so it is necessary to use scissors to cut the separating plastic block first, so that the separating plastic block can be separated from the concave plastic plate.
[0024] The locking tongue in this embodiment is a disposable item, and the concave plastic plate is provided with a mark 19, which can be different numbers, letters or names.
[0025] In this embodiment, the stationery bag body is closed by pulling the zipper head. The square opening on the zipper head is then fitted onto the first protrusion, and the latch is inserted into the latch opening. Because both the first and second elastic bevels have a certain angle and elasticity, they can pass sequentially through the spherical protrusion on the latch opening, thus locking the stationery bag. Since the first and second elastic bevels form a common blocking force, the latch is relatively difficult to retract. To open, scissors are needed to first cut the plastic block, and then the latch is pulled downwards to open the stationery bag.
[0026] In this embodiment, the plastic block must first be cut with scissors before the disposable latch can be pulled down to open the pencil case. If the pencil case is opened by someone else, the owner will be notified.
[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
