Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to an embedded printer assembly structure that can be quickly disassembled and assembled. Background Technology

[0002] Thermal printers, with their efficient and convenient printing characteristics, have been widely used in various scenarios such as logistics label printing and medical test report output. Their core components include the printhead, pressure roller, and control board, which are typically integrated inside the printer body and encased in an external protective housing to ensure stable operation and the safety of internal components. However, in actual use, the printhead may operate at high temperatures for extended periods. For example, in high-frequency scenarios such as logistics, the daily printing volume often exceeds 5,000 times, causing significant heat generation in related electronic components. This makes internal components prone to malfunctions such as wear of the thermal coating and aging of circuits. Therefore, it is necessary to periodically disassemble the printer body from the housing for structural repair and maintenance or replacement of consumables.

[0003] However, in existing technologies, the protective shell of thermal printers is mostly fixed to the printer body using screws. Disassembly and assembly require specific tools (such as a particular type of screwdriver), and when there are many screws, each screw must be removed and installed individually, which undoubtedly consumes a lot of time and makes it difficult to improve overall disassembly and assembly efficiency. Furthermore, the threaded structure is prone to stripping after repeated disassembly and assembly, leading to loose connections and causing many inconveniences for normal printer use. In view of this, this application aims to provide a printer assembly structure that allows for quick disassembly and assembly. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an embedded printer assembly structure that can be quickly disassembled and assembled.

[0005] The technical solution of this utility model is: an embedded printer assembly structure that can be quickly disassembled and assembled, including a printer body and a protective shell. A first connecting mechanism is provided on the inner side of the protective shell, and a second connecting mechanism is provided on the printer body. The first connecting mechanism and the second connecting mechanism cooperate to realize the detachable connection between the printer body and the protective shell. The first connecting mechanism includes a fixing buckle post and a limiting post. The second connecting mechanism includes an elastic buckle piece and a spring handle. The spring handle is fixed on the elastic buckle piece, and pressing the spring handle will cause the position of the elastic buckle piece to shift.

[0006] Furthermore, the printer body includes a support frame, the elastic buckle is disposed on the support frame, and the elastic buckle extends outward from a certain side of the support frame, with a hook provided at the top of the elastic buckle.

[0007] Furthermore, the position and number of the fixing buckle posts correspond to the elastic buckle pieces, and the fixing buckle posts are provided with grooves that cooperate with the hooks.

[0008] Furthermore, the position of the limiting post matches the support frame. When the hook of the elastic buckle piece engages with the groove of the fixing buckle post, the limiting post and the support frame also engage tightly, making it difficult for the printer body and the protective shell to move relative to each other.

[0009] Furthermore, a notch is designed on the support frame at the position where the elastic buckle is provided. The bottom end of the elastic buckle is connected to the bottom of the notch, and the two sides of the elastic buckle do not contact the two sides of the notch. Preferably, the elastic buckle is integrally formed with the support frame.

[0010] Furthermore, the spring clip handle is positioned closer to the bottom of the elastic latching piece; and the extension direction of the spring clip handle is opposite to that of the elastic latching piece, causing the outer end of the spring clip handle to be away from the top of the elastic latching piece. Thus, when the outer end of the spring clip handle is pressed, the top of the elastic latching piece will shift outwards. Based on this characteristic, when the printer body and protective housing are in the fixed installation state, pressing the spring clip handle will cause the hook at the top of the elastic latching piece to move out of the groove of the fixing latch post, allowing the printer body and protective housing to separate quickly.

[0011] Furthermore, the spring clip handle is set at an angle to the surface of the supporting frame. The preferred range of the angle is 15-30 degrees. Preferably, the spring clip handle and the elastic buckle are integrally formed.

[0012] Furthermore, there are multiple elastic buckle pieces, which are symmetrically arranged on two opposite sides of the support frame.

[0013] Furthermore, a limiting part is provided at the top of the limiting post, and the limiting part is an L-shaped contact surface.

[0014] Furthermore, an elastic material layer is provided on the surface of the limiting part. The elastic material layer can be a rubber layer adhered to the surface. The function of the elastic material layer is to provide a flexible buffer layer between the first connecting mechanism and the second connecting mechanism, so as to avoid severe wear due to rigid contact, which could lead to easy loosening of the connecting structure.

[0015] The beneficial effects of this utility model are as follows: The quick-disassembly embedded printer assembly structure of this utility model achieves quick disassembly and assembly by designing a first connecting mechanism and a second connecting mechanism on the protective shell and the printer body respectively; it can be directly disassembled and assembled without the need for other disassembly and assembly tools, thus improving the efficiency of printer installation and maintenance.

[0022] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Example

[0023] like Figures 1-5 As shown, this embodiment is a quick-assembly and disassembly embedded printer assembly structure, including a printer body 2 and a protective housing 1. A first connecting mechanism is provided on the inner side of the protective housing 1, and a second connecting mechanism is provided on the printer body 2. The first connecting mechanism and the second connecting mechanism cooperate to realize the detachable connection between the printer body 2 and the protective housing 1. The first connecting mechanism includes a fixing buckle post 11 and a limiting post 12. The second connecting mechanism includes an elastic buckle piece 22 and a spring handle 23. The spring handle 23 is fixed on the elastic buckle piece 22. Pressing the end of the spring handle 23 will cause the top end of the elastic buckle piece 22 to shift.

[0024] In this embodiment, the printer body 2 includes a support frame 21. The elastic clip 22 is disposed on the support frame 21 and extends outward from one side of the support frame 21. A hook 24 is provided at the top of the elastic clip 22. The position and number of fixing clip posts 11 correspond to the elastic clip 22. A groove 13 is provided on the fixing clip post 11 to cooperate with the hook 24. The position of the limiting post 12 matches the support frame 21. When the hook 24 of the elastic clip 22 cooperates with the groove 13 of the fixing clip post 11, the limiting post 12 also closely cooperates with the support frame 21, making it difficult for the printer body 2 and the protective housing 1 to move relative to each other. An inclined surface is provided on both the hook 24 and the fixing clip post 11, which facilitates smoother cooperation when they approach each other.

[0025] In this embodiment, a notch is designed on the support frame 21 at the position where the elastic buckle 22 is provided. The bottom end of the elastic buckle 22 is connected to the bottom of the notch, and the two sides of the elastic buckle 22 do not contact the two sides of the notch. The spring handle 23 is connected to the elastic buckle 22 closer to the bottom end of the elastic buckle 22; and the extension direction of the spring handle 23 is opposite to that of the elastic buckle 22, so that the outer end of the spring handle 23 is away from the top end of the elastic buckle 22. The spring handle 23 is set at an angle to the surface of the support frame 21, and the angle can be 15-30 degrees.

[0026] In this embodiment, the spring clip 23, the elastic latching piece 22, and the support frame 21 are integrally formed. There are four elastic latching pieces 22, symmetrically arranged on two opposite sides of the support frame 21. A limiting portion is provided at the top of the limiting post 12, and the limiting portion is an L-shaped contact surface. In other embodiments, an elastic material layer can be provided on the surface of the limiting portion. The elastic material layer can be a rubber layer adhered to the surface. The function of the elastic material layer is to provide a flexible buffer layer between the first connecting mechanism and the second connecting mechanism, preventing wear due to rigid contact and thus avoiding loosening of the connecting structure.

[0027] In this embodiment, the hook part

[0028] The working principle of this embodiment is as follows: When the outer end of the spring handle 23 is pressed, the top of the elastic latching piece 22 will shift outward. After the spring handle 23 is released, the top of the elastic latching piece 22 will return to its original position. Based on this characteristic, when the printer body 2 and the protective housing 1 are in the installed and fixed state, pressing the spring handle 23 will cause the top of the elastic latching piece 22 to shift outward, and the hook 24 will move out of the groove 13 of the fixing latching post 11, so that the printer body 2 and the protective housing 1 can be quickly separated. When the printer body 2 and the protective housing 1 are in the separated state, the printer body 2 and the protective housing 1 can be brought closer to each other, and the elastic latching piece 22 and the fixing latching post 11 will be positioned opposite each other until the hook 24 of the elastic latching piece 22 just engages in the groove 13 of the fixing latching post 11. At the same time, under the cooperative action of the limiting post 12, the printer body 2 and the protective housing 1 will remain relatively stationary, that is, the two are tightly connected together.

[0029] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
