[0027] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0028] A power-contact printer includes a printer body 1, a power supply unit 2, and a contact unit 3. The printer body 1 has a power supply slot 11 for assembling the power supply unit 2. The contact unit 3 is installed on the printer body 1 and includes a positive connection group 31, a negative connection group 32, and multiple elastic members. The positive connection group 31 and the negative connection group 32 are arranged at intervals. The inner end of the elastic member is fixed, and the outer end of the elastic member is mated with the positive connection group 31 or the negative connection group 32. The elastic member is used to cause the positive connection group 31 or the negative connection group 32 to pop out in the direction toward the power supply slot 11. The power supply unit 2 has a source connection part, and the positive connection group 31 and the negative connection group 32 are used to synchronously contact the source connection part.

[0029] The aforementioned power supply-tight contact printer assembles the power supply component 2 into the power supply slot 11. Through the contact component 3 and the source connection, the power supply component 2 supplies power to the printer body 1, achieving flexible power supply. The printer does not need to rely on mains power or be affected by cables, making it easy to disassemble and replace the power supply component 2. At the same time, the positive connection group 31 and the negative connection group 32 have a large contact area with the source connection. Combined with the elastic force of the elastic component, the contact tightness between the positive connection group 31 and the negative connection group 32 and the source connection can be improved, thereby effectively improving the conductivity reliability between the printer body 1 and the power supply component 2 and ensuring the normal use of the printer body 1.

[0030] The elastic element can be a spring, a rubber block, or a sheet.

[0031] The power supply section includes a positive power supply plate 21 and a negative power supply plate 22, which connect the positive and negative terminals of the power supply unit 2.

[0032] The positive connection group 31 includes multiple positive connection blocks arranged at intervals. An elastic element is used to cause the positive connection blocks to pop out in the direction toward the power supply slot 11, and the multiple positive connection blocks are simultaneously arranged to abut against and conduct with the positive source plate 21. The negative connection group 32 includes multiple negative connection blocks arranged at intervals. An elastic element is used to cause the negative connection blocks to pop out in the direction toward the power supply slot 11, and the multiple negative connection blocks are simultaneously arranged to abut against and conduct with the negative source plate 22.

[0033] In this way, under the action of the elastic element, a force is applied to the positive connection group 31 and the negative connection group 32, which improves the tightness of the contact between the positive connection group 31 and the negative connection group 32 and the source connection part, and ensures the reliability of the conduction between the printer body 1 and the power supply unit 2.

[0034] Furthermore, by setting up multiple positive connection blocks, the reliability of the conduction between the positive connection group 31 and the source connection is ensured through the coordinated action of each positive connection block.

[0035] Furthermore, by setting up multiple negative connection blocks, the reliability of the conduction between the negative connection group 32 and the source connection is ensured through the coordinated action of each negative connection block.

[0036] The positive contact block has a positive contact surface. When the power supply component 2 is assembled into the power supply slot 11, the positive contact surface and the positive source plate 21 are arranged in a flat contact arrangement. In this way, the contact area between the positive contact surface and the positive source plate 21 is increased, thereby improving the contact tightness between the positive contact block and the positive source plate 21.

[0037] The positive contact block has a positive guide surface, and the lower part of the positive guide surface is arranged to meet the positive contact surface. Along the top-to-bottom direction, the positive guide surface is arranged to gradually slope downwards. When the power supply component 2 is assembled with the printer body 1, under the guidance of the positive guide surface, the power supply component 2 can gradually press down on the positive contact block, causing the positive contact block to swing inwards. At this time, the downward pressure overcomes the elastic force of the elastic element, causing the positive contact block to swing inwards. At this time, the compression degree of the elastic element gradually increases until the assembly of the power supply component 2 is completed. At this time, the elastic force of the elastic element pushes the positive contact block against the positive source plate 21 in the opposite direction, ensuring the tight contact between the positive contact surface and the positive source plate 21.

[0038] The outer end of the elastic element is arranged in a mating position with the middle part of the positive guide surface. The elastic element is used to apply elastic force to the positive guide surface. In this way, by applying elastic force to the positive guide surface, the elastic element pushes the positive contact block against the positive source plate 21, ensuring the tight contact between the positive contact surface and the positive source plate 21.

[0039] The negative contact block has a negative contact surface. When the power supply component 2 is assembled into the power supply slot 11, the negative contact surface and the negative source plate 22 are arranged in a flat contact arrangement. In this way, the contact area between the negative contact surface and the negative source plate 22 is increased, thereby improving the tightness of the contact between the negative contact block and the negative source plate 22.

[0040] The negative contact block has a negative guide surface, with the lower part of the negative guide surface aligned with the negative contact surface. The negative guide surface gradually slopes downwards from top to bottom. When the power supply component 2 is assembled with the printer body 1, the negative guide surface guides the power supply component 2 to gradually press down on the negative contact block, causing the negative contact block to swing inwards. At this time, the downward pressure overcomes the elastic force of the elastic element, causing the negative contact block to swing inwards. The compression degree of the elastic element gradually increases until the assembly of the power supply component 2 is completed. At this time, the elastic force of the elastic element pushes the negative contact block against the negative source plate 22, ensuring the tight contact between the negative contact surface and the negative source plate 22.

[0041] The outer end of the elastic element is arranged in a mating position with the middle part of the negative guide surface. The elastic element is used to apply elastic force to the negative guide surface. In this way, by applying elastic force to the negative guide surface, the elastic element pushes the negative contact block against the negative source plate 22, ensuring the tight contact between the negative contact surface and the negative source plate 22.

[0042] The printer body 1 includes a power supply housing, which forms a power supply slot 11. The power supply housing includes an outer shell plate, an inner shell plate, and an outer shell plate. The inner shell plate and the outer shell plate are arranged at intervals along the length of the power supply component 2. The outer shell plate has a plate opening, which is arranged through the power supply component 2. The power supply component 2 has a charging port, which is arranged correspondingly to and connected to the plate opening.

[0043] In this way, when mains power is available, the power supply unit 2 can be charged so that the printer body 1 can be used later.

[0044] The inner shell plate has a plate fastening groove 12, and the power supply component 2 includes a source fastening part 23. The source fastening part 23 is arranged to be fastened or separated from the plate fastening groove 12. Through the cooperation between the source fastening part 23 and the plate fastening groove 12, the assembly and disassembly of the power supply component 2 and the printer body 1 can be realized. At the same time, under the action of the source fastening part 23, there is sufficient fastening force to ensure the assembly stability of the power supply component 2 and the printer body 1.

[0045] The power supply housing has a top shell plate, the top surface of the power supply component 2 is stacked with the top shell plate, and the bottom surface of the power supply component 2 is suspended; this avoids heat accumulation in the power supply component 2 and facilitates heat dissipation of the power supply component 2. Example

[0046] The printer body 1 includes a power supply housing, which forms a power supply slot 11. The power supply housing includes an inner shell plate, and a contact member 3 is installed on the inner shell plate. Along the length of the power supply member 2, the inner shell plate and the power supply member 2 are arranged in a corresponding manner. This allows the contact member 3 to be positioned on the top, and facilitates the assembly and disassembly of the power supply member 2 and the printer body 1. Example

[0047] The printer body 1 includes a power supply housing, which forms a power supply slot 11. The power supply housing includes a side shell plate. Along the width direction of the power supply component 2, the inner shell plate is arranged correspondingly to the power supply component 2. The contact component 3 is installed on the side shell plate. This realizes the side setting of the contact component 3 and facilitates the assembly and disassembly of the power supply component 2 and the printer body 1.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
