[0044] Existing technology provides a platform scale mechanism with an external printing mechanism mounted on the surface of its column. This external printing mechanism includes a support plate and an external printer. The support plate is bolted to the surface of the column, and the external printer is placed on or suspended from the surface of the support plate. In other words, the printer is mounted to the column by directly placing or suspending it on the support plate. However, while this method of mounting the printer directly or by suspending it facilitates assembly, it is prone to printer shaking or even falling, resulting in unstable installation.

[0045] In response, this embodiment provides a printer mounting structure that ensures easy installation of the printer body on the column while providing a stable connection between the printer body and the column, and can be used in the field of printer technology.

[0046] Reference Figures 1-12 The printer mounting structure includes a printer housing 1 for mounting the printer body 100 and a printer bracket 2 for fixing it to a column 200. The printer housing 1 and the printer bracket 2 each have a slide groove 3 and a slide rail 4. A first insert 31 is provided on the bottom wall of the slide groove 3, forming a first slot 32 between the first insert 31 and the bottom wall of the slide groove 3. The slide rail 4 includes a second insert 41 disposed on the slide groove 3, forming a second slot 42 between the second insert 41 and the slide groove 3. The slide rail 4 is slidable relative to the slide groove 3, having a detachable position and an installable position. When the slide rail 4 is in the installable position, along the sliding direction of the slide rail 4 (the sliding direction of the slide rail 4 is...) Figures 1-2In the AB direction (as shown in the diagram), the first insert 31 is inserted into the second slot 42, and the second insert 41 is inserted into the first slot 32. When the slide rail 4 is in the disassembled position, the first insert 31 separates from the second slot 42, and the second insert 41 separates from the first slot 32. This allows the slide groove 3 and the slide rail 4 to engage with each other through the insertion of the first insert 31 into the second slot 42 and the insertion of the second insert 41 into the first slot 32, preventing them from separating. This ensures a stable connection between the printer housing 1 and the printer bracket 2, and consequently, a stable connection between the printer body 100 and the column 200. Furthermore, this printer mounting structure connects the slide groove 3 and the slide rail 4 through a sliding engagement. The position of the slide rail 4 can be switched by sliding it. When the slide rail 4 is in the mounting position, the printer body 100 and the column 200 are stably connected. When the slide rail 4 is in the disassembled position, it facilitates the assembly and disassembly of the two components. This embodiment exemplarily provides a scheme where the slide groove 3 is located in the printer housing 1 and the slide rail 4 is located in the printer bracket 2.

[0047] Continue to refer to Figures 1-12 The bottom wall of the slide groove 3 is provided with two first inserts 31, which form two first slots 32 between themselves and the bottom wall of the slide groove 3. The openings of the two first slots 32 are opposite in direction, so that after the slide groove 3 is assembled with the slide rail 4, the slide rail 4 can only move along its original sliding direction, preventing it from moving in other directions. Correspondingly, two second inserts 41 are provided, which form two second slots 42 between themselves and the second insert. The two first inserts 31 can be inserted into the two second slots 42 one-to-one, and the two second inserts 41 can be inserted into the two first slots 32 one-to-one. In this embodiment, the openings of the two first slots 32 are opposite to each other, and correspondingly, the openings of the two second slots 42 are facing each other.

[0048] Continue to refer to Figures 1-12 The bottom wall of the slide groove 3 is provided with a third insert 33, and a third slot 34 is formed between the third insert 33 and the bottom wall of the slide groove 3; the slide rail 4 includes a fourth insert 43 disposed thereon, and a fourth slot 44 is formed between the fourth insert 43 and the slide rail 4; when the slide rail 4 is in the installation position, the third insert 33 is inserted into the fourth slot 44 along the sliding direction of the slide rail 4, and the fourth insert 43 is inserted into the third slot 34; when the slide rail 4 is in the disassembly position, the third insert 33 is separated from the fourth slot 44, and the fourth insert 43 is separated from the third slot 34, so that the slide groove 3 and the slide rail 4 are further engaged with each other through the insertion between the third insert 33 and the fourth slot 44 and the insertion between the fourth insert 43 and the third slot 34, thereby improving the stability of the connection between the two.

[0049] Continue to refer to Figures 1-12The bottom wall of the slide groove 3 is provided with two third inserts 33, which form two third slots 34 with the bottom wall of the slide groove 3. The openings of the two third slots 34 are opposite, thereby further preventing the slide rail 4 from moving in other directions after the slide groove 3 is assembled with the slide rail 4. Correspondingly, two fourth inserts 43 are provided, which form two fourth slots 44 with the second insert. The two third inserts 33 can be inserted into the two fourth slots 44 one-to-one. In this embodiment, the openings of the two third slots 34 are opposite to each other, and correspondingly, the openings of the two fourth slots 44 are facing each other.

[0050] Continue to refer to Figures 1-12 The bottom wall of the slide 3 is provided with a first connecting strip 35. The first connecting strip 35 has a first extension section 351, a second extension section 352, and a third extension section 353 connected in sequence. A first insert 31 protrudes from the side wall of the first extension section 351, and a third insert 33 protrudes from the side wall of the third extension section 353. The end face of the third insert 33 is flush with the side wall surface of the second extension section 352. The extension directions of the first insert 31 and the third insert 33 are the same. Along the extension directions of the first insert 31 and the third insert 33, the height of the end face of the third insert 33 is flush with the surface of the second extension section 352, and the height of the end face of the first insert 31 is higher than the height of the end face of the third insert 33. During the movement of the slide rail 4 from the disassembly position to the installation position, the second insert 41 abuts against the surface of the second extension section 352, thereby restricting the movement direction of the slide rail 4. The slide rail 4 includes a second connecting strip 45 protruding from the second rail. The second connecting strip 45 has a fourth extension section 451 and a fifth extension section 452 connected in sequence. A second insert 41 protrudes from the side wall of the fourth extension section 451, and a fourth insert 43 protrudes from the side wall of the fifth extension section 452. The second insert 41 and the fourth insert 43 extend in the same direction. Along the extension directions of the second insert 41 and the fourth insert 43, the height of the end face of the fourth insert 43 is higher than the height of the end face of the second insert 41, thereby enabling the first insert 31 to engage with the second slot 42, and the second insert 41 to engage with the first slot 32. Simultaneously, the third insert 33 can engage with the fourth slot 44, and the fourth insert 43 can engage with the third slot 34.

[0051] Optionally, two first connecting strips 35 are provided, spaced apart. Two first inserts 31, two third inserts 33, and two first connecting strips 35 are arranged in a one-to-one correspondence, with the extension directions of the two first inserts 31 and the two third inserts 33 being opposite. In this embodiment, specifically, the extension directions of the two first inserts 31 and the two third inserts 33 are opposite. Correspondingly, two second connecting strips 45 are provided, spaced apart. Two second inserts 41, two fourth inserts 43, and two second connecting strips 45 are arranged in a one-to-one correspondence, with the extension directions of the two second inserts 41 and the two fourth inserts 43 being opposite. In this embodiment, specifically, the extension directions of the two second inserts 41 and the two fourth inserts 43 are opposite.

[0052] Continue to refer to Figures 1-12 The printer housing 1 and the printer bracket 2, the first of which has a slot 51, and the second of which has a protruding elastic block 52, when the slide rail 4 is in the disassembled position, the elastic block 52 can elastically deform and abut against the first one. When the slide rail 4 is in the installed position, the elastic block 52 is inserted into the slot 51 along a first direction, the first direction being perpendicular to the sliding direction of the slide rail 4 (the first direction is...). Figures 1-2 (CD direction in the diagram). This design, through the interlocking of the elastic block 52 and the slot 51, prevents the elastic block 52 from dislodging from the slot 51 when the slide rail 4 is in the installation position, thus ensuring stable installation of the printer housing 1 and the printer bracket 2. Simultaneously, when the user slides the slide rail 4 to the installation position, the interlocking of the elastic block 52 and the slot 51 also serves as a reminder that the slide rail 4 is properly installed. This embodiment exemplifies a design where the printer housing 1 has a slot 51 and the printer bracket 2 has a protruding elastic block 52.

[0053] Continue to refer to Figures 1-12 The printer housing 1 has a bracket receiving groove 11, and the printer bracket 2 is inserted into the bracket receiving groove 11. The side wall of the printer bracket 2 abuts against the side wall of the bracket receiving groove 11. This arrangement can play a certain limiting role, restricting the relative movement direction between the printer housing 1 and the printer bracket 2. After the slide rail 4 and the slide groove 3 are assembled, the printer housing 1 and the printer bracket 2 can only slide relative to each other.

[0054] Continue to refer to Figures 1-12The printer bracket 2 is fixedly connected to the column 200 by fasteners 7. The fasteners 7 pass through the printer bracket 2 and are threadedly connected to the column 200. Specifically, the fasteners 7 are screws. The printer bracket 2 also has a protruding positioning post 21. The column 200 has a positioning hole 201, and the positioning post 21 is inserted into the positioning hole 201. This allows for quick positioning of the printer bracket 2 and the column 200, and the fasteners 7 detachably fix them together. The column 200 also has a threaded hole 202 with internal threads, and the fasteners 7 are threadedly engaged with the threaded hole 202.

[0055] This embodiment also provides a printer assembly. In this embodiment, the printer assembly is applied to the original structure, while in other embodiments, the printer assembly can also be applied to other structures. The printer assembly includes the above-described printer mounting structure and a printer body 100. The printer body 100 is mounted on the printer housing 1 of the printer mounting structure. The printer bracket 2 of the printer mounting structure is used to fix it on the column 200. In this printer mounting structure, the slide groove 3 and the slide rail 4 are mutually engaged through the insertion of the first insert 31 and the second slot 42 and the insertion of the second insert 41 and the first slot 32, preventing them from separating from each other. This allows the printer housing 1 and the printer bracket 2 to be stably connected, thereby ensuring a stable connection between the printer body 100 and the column 200. Furthermore, the printer mounting structure is connected to the slide rail 4 through a sliding engagement of the slide groove 3. The position of the slide rail 4 can be switched by sliding the slide rail 4. When the slide rail 4 is in the mounting position, the printer body 100 and the column 200 are stably connected. When the slide rail 4 is in the disassembly position, it facilitates the assembly and disassembly of the two.

[0056] Continue to refer to Figures 1-12 The printer assembly also includes wires and a wire guide structure 61. The column 200 has a first through hole 62, the printer bracket 2 has a second through hole 63, and the printer housing 1 is provided with a plug. The plug is electrically connected to the printer body 100. The wires pass through the first through hole 62 and the second through hole 63 in sequence and are electrically connected to the plug. The wire guide structure 61 is provided on the printer bracket 2 and has a guide surface 611. Along the direction away from the printer bracket 2, the guide surface 611 gradually approaches the plug, so that the wires can be guided along the direction close to the plug through the guide surface 611, which facilitates assembly.

[0057] Optionally, two first connecting strips 35 are spaced apart on the bottom wall of the slide groove 3. After the slide rail 4 and the slide groove 3 are assembled, the wire guide structure 61 is always located between the two first connecting strips 35, thereby avoiding the wire guide structure 61 from affecting the relative sliding between the slide groove 3 and the slide rail 4.

[0058] Continue to refer to Figures 1-12The wire guiding structure 61 includes a fixed end 612 and a guiding end 613 disposed on the fixed end 612. The guiding surface 611 is located on the guiding end 613. The fixed end 612 is located between the printer bracket 2 and the column 200, and both ends of the fixed end 612 can abut against the printer bracket 2 and the column 200 respectively. One of the printer bracket 2 and the fixed end 612 is provided with a connecting post 64, and the other has a positioning groove 65. The connecting post 64 is inserted into the positioning groove 65, thereby fixing the fixed end 612 between the printer bracket 2 and the column 200 and preventing the wire guiding structure 61 from detaching from the above structure.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
