[0007] A further implementation scheme of the utility model is that the power adapter is installed in the bottom of the machine body shell.

[0008] A further implementation scheme of the utility model is that a positioning seat is formed in the body shell, and the power adapter can be positioned and accommodated between the positioning seat and the side plate of the body shell.

[0009] A further implementation scheme of the utility model is that the positioning seat and the side panel are formed with relative positioning buckles, the lower part of the positioning buckle is a limit block, and the outer side of the power adapter is formed with a limit strip and a positioning groove, the limit strip and the positioning groove are arranged up and down, and when the power adapter slides between the positioning seat and the side panel, the positioning buckle and the positioning groove are snap-fitted, and the limit block fits the limit strip.

[0010] A further implementation scheme of the utility model is that a socket connected to the PCB mainboard is provided in the body shell, and a power guide column is provided inside the power adapter, and the power guide column is inserted into the socket to connect to the PCB mainboard.

[0011] Another solution includes a receipt printer, including the body shell and power adapter mounting structure described in any one of the above solutions.

[0012] The beneficial effects of the utility model are:

[0013] The power adapter is installed in the body shell in a built-in form to achieve an integrated installation. When the power adapter is pushed between the side panel and the positioning seat, the positioning buckle is just inserted into the positioning groove, and the positioning block fits the positioning bar to install the power adapter in place. The power guide column is inserted into the jack to connect the PCB motherboard; when disassembling, the power adapter can be quickly removed by pushing it out in reverse. The integrated installation in a built-in form can avoid occupying external space and is convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0018] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0019] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0020] It should be noted that, in the description of the present application, the orientation or positional relationship indicated by terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; the orientation words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0021] It should be noted that, in the present application, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises one..." does not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted or combined.

[0023] This embodiment provides a mounting structure of a housing 1 and a power adapter 2 , including a housing 1 and a power adapter 2 .

[0024] Among them, the power adapter 2 is slidably installed with the body shell 1, and the power adapter 2 is built into the body shell 1 and electrically connected to the PCB main board (not shown in the figure), realizing the built-in integrated installation of the power adapter 2, which can avoid occupying external space and is also convenient to carry.

[0025] For example, the power adapter 2 is installed in the bottom of the body shell 1.

[0026] Specifically, Figure 2 A positioning seat 10 is formed in the body shell 1, and the positioning seat 10 and the side plate of the body shell 1 can be positioned to accommodate the power adapter 2. More specifically, the positioning seat 10 and the side plate are formed with opposing positioning buckles 11, and two positioning buckles 11 are provided on each side, which are spaced and distributed on the same horizontal line. The lower part of the positioning buckle 11 is a limit block 12, and a limit strip 20 and a positioning groove 21 are formed on the outer side of the power adapter 2. The limit strip 20 and the positioning groove 21 are arranged up and down, such as Figure 3 When the power adapter 2 slides between the positioning seat 10 and the side panel, the positioning buckle 11 and the positioning groove 21 are engaged, and the limit block 12 fits the limit strip 20. This position is the in-place assembly of the power adapter 2. In addition, a socket 13 connected to the PCB mainboard is opened in the body shell 1. The inner side of the power adapter 2 is a power guide column 22. The power guide column 22 is inserted into the socket 13 to connect the PCB mainboard, so as to connect the power adapter 2 and the PCB mainboard. When disassembling, the power adapter 2 is pushed out in the reverse direction to achieve quick removal, making the disassembly and assembly process simple and reliable.
