Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purpose, the following detailed description of the embodiments, structural features and effects of the present invention will be made with reference to the accompanying drawings and examples.

Example 1

Referring to the attached drawings 1-10, the utility model provides a pair of novel printer paper storehouse structure, including printer paper storehouse 1 and fender paper structure 2, printer paper storehouse 1 is used for placing printing paper, and it is for holding the chamber structure, and 1 volume in traditional printer paper storehouse is fixed, or can only put small-size printing paper, perhaps large-scale printing paper, unable adjustment, and then can only adapt to the placing that a kind of width was beaten printing paper.

In this embodiment, the added paper blocking structure 2 can move in the printer paper bin 1 before the printing paper is placed, so as to form a printing paper placing area with variable width for placing printing paper with different widths. Through such improvement, the inside size etc. of 1 body in printer paper storehouse need not to change, and the fender paper structure 2 that increases divides it, forms two regions, certainly, when being used for the printing paper of broad to place, another region can be very little, even the structure that two boards are next, but can satisfy the placing of different width printing paper, obtains further optimization with the function in printer paper storehouse 1 on the one hand, and on the other hand, when can placing multiple printing paper, the application of printer has obtained the extension.

Specifically, in this embodiment, a clamping groove is provided on the printer paper bin 1, and the paper blocking structure 2 is inserted into the clamping groove and moves in the clamping groove, so that the change of the width of the printing paper placing area is realized. In this embodiment, in order to lock the paper blocking structure 2 with the adjusted width, the paper blocking structure further includes a locking mechanism 3, the locking mechanism 3 includes a locking portion 301, and a receiving portion 201 matched with the locking portion 301 is disposed at a position of the paper blocking structure 2 close to the slot; specifically, the paper blocking structure 2 is an elastic part and can be made of plastic; when the paper blocking structure 2 moves to a specified position in the printer paper bin 1, the locking part 301 is forced to be clamped into the accommodating part 201, so that the paper blocking structure 2 is deformed and locked in the clamping groove.

The containing part 201 is arranged near the clamping groove, so that when the containing part 201 deforms under stress, the whole paper blocking structure 2 tightly holds the clamping groove to realize quick locking.

In the embodiment, the paper blocking structure 2 is placed in the printer paper bin 1, so that the width of the printing paper placing area can be changed, and the printing paper box is simple in structure, convenient to produce and convenient to install; when the printer is used for common thermal printing paper, the width of a printing paper placing area in the printer paper bin 1 is adjusted to 57mm or the specification of 80mm thermal sensitive small ticket paper, namely 57mm and 80mm, by moving the paper blocking structure 2; when the thermal label paper is used for label printing paper, the width of a printing paper 4 placing area in the printer paper bin 1 is adjusted to be 30 mm-80 mm in specification of the thermal label paper with the size of 30 mm-80 mm by moving the paper blocking structure 2.

In this embodiment, utilize to remove the principle that changes the width, ingenious setting in printer paper storehouse 1 keeps off paper structure 2 to through its width adjustable function that has realized in the printer paper storehouse 1 that the printing paper placed the position, and then make it realize ordinary thermal printing paper and the effect that the label beat the compatible installation of printing paper. Meanwhile, by utilizing the principle of stress deformation, when the locking mechanism 3 is pulled up, the paper blocking structure 2 is kept in an original state and can move left and right in the printer paper bin 1, when the paper blocking structure 2 moves to a paper width position and needs to be fixed, the locking mechanism 3 is pressed down, a locking part 301 below the locking mechanism 3 is contacted with an accommodating part 201 at the lower part in the middle of the paper blocking structure 2, the paper blocking structure is supported to be opened towards two sides and slightly deformed, so that the friction force between the paper blocking structure and the clamping groove is increased, and the purpose of locking is achieved. When the paper width was adjusted to needs, the dead mechanism of pulling-up 3, the dead portion of lock 301 of its below breaks away from the portion 201 that holds that keeps off the 2 lower parts of paper structure, no longer plays a role, keeps off paper structure deformation and disappears, and the reconversion, frictional force reduces to guarantee to keep off paper structure 2 and can freely slide in printer paper storehouse 1.

In this embodiment, the card slot is a very mature technology, and the preparation is easily realized.

Example 2

Referring to fig. 10, as a further modification of the above embodiment 1, in this embodiment, a fixing portion 302 is further provided on the locking mechanism 3, and the fixing portion 302 is fixed to the paper blocking structure 2. In this embodiment, the addition of the fixing portion 302 ensures that the locking mechanism 3 can be fixed no matter what state the locking portion 301 is in, and the locking mechanism 3 is not lost, and is convenient to use. Meanwhile, the fixing part 302 is added, the locking mechanism 3 is fixed on the paper blocking structure 2 and is combined with the paper blocking structure 2 into a whole, so that the paper blocking structure is convenient to install and use.

Referring to fig. 4-5, in order to realize a specific fixing manner, in this embodiment, an insertion cavity 202 is further formed on the paper blocking structure 2, and the insertion cavity 202 is used for inserting and temporarily fixing the fixing portion 302. Compared with the mode of bolt fixing and the like, the arrangement of the insertion cavity 202 can save space and improve the space utilization rate. Of course, the fixing may be performed by bolts or the like.

In this embodiment, the insertion cavity 202 and the fixing portion 302 are respectively a wedge-shaped groove and a wedge-shaped structure with a wide top and a narrow bottom, which are matched with each other, so as to facilitate the insertion thereof.
