DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] Please refer to Figures 1 to 3In some embodiments, the carbon tape cartridge 10 comprises a shell 1, a reel 2 and a resilient member 3, the shell 1 comprises a lower shell 11 and a cover 12 arranged on the lower shell 11, an inner side wall of the cover 12 is provided with a plug-in protrusion 121 and a first limiting structure 122 arranged on the periphery of the plug-in protrusion 121, the reel 2 is installed in the lower shell 11 and is rotationally connected with the plug-in protrusion 121, the resilient member 3 is sleeved on the plug-in protrusion 121 and is compressed between the reel 2 and the first limiting structure 122, and an end of the resilient member 3 away from the reel 2 is provided with a first anti-rotation structure 31 which cooperates with the first limiting structure 122 to limit the rotation of the resilient member 3 in a first direction.

[0042] Optionally, the inside of the lower shell 11 can be formed with a receiving cavity, the reel 2 is arranged in the receiving cavity, and the reel 2 can be used to wind the carbon tape 4. More specifically, the reel 2 can be used to feed the carbon tape 4 for use by the printer 100, or the reel 2 can be used to collect the carbon tape 4 that has been used by the printer 100.

[0043] The resilient member 3 is a spring, the plug-in protrusion 121 extends towards the receiving cavity, so that the reel 2 in the receiving cavity is rotationally connected with the plug-in protrusion 121, the resilient member 3 is sleeved on the plug-in protrusion 121 and is compressed between the first limiting structure 122 and the first end of the reel 2. It should be noted that the end of the reel 2 close to the cover 12 is the first end, and the end of the reel 2 away from the cover 12 is the second end. The resilient member 3 is in a compressed state, so that the resilient member 3 can drive the second end of the reel 2 to abut against the inner side wall of the lower shell 11, thereby increasing the friction between the reel 2 and the lower shell 11, so that a certain driving force is required to rotate the reel 2, thereby reducing the occurrence of false rotation of the reel 2.

[0044] In the present embodiment, the first limiting structure 122 is located on the periphery of the plug-in protrusion 121 and protrudes relative to the inner side wall of the cover 12. The first limiting structure 122 can provide support for the resilient member 3. The end of the resilient member 3 away from the reel 2 is provided with the first anti-rotation structure 31 which extends away from the reel 2. When the reel 2 rotates in the first direction, the first anti-rotation structure 31 can abut against the first limiting structure 122 to limit the rotation of the resilient member 3 in the first direction, thereby preventing the reel 2 from rotating in the first direction while driving the resilient member 3 to rotate together, so that the resilient member 3 is stably installed and can stably provide the axial compression force for the reel 2.

[0045] Please refer to Figure 2 and Figure 3 In some embodiments, the first limiting structure 122 and the first anti-rotation structure 31 are arranged along the circumference of the plug-in protrusion 121, and the first limiting structure 122 is located on the movement track of the first anti-rotation structure 31 in the first direction.

[0046] It should be noted that during the rotation of the reel 2 in the first direction, the reel 2 drives the elastic member 3 to rotate in the first direction by a certain angle until the first anti-rotation structure 31 contacts the first limiting structure 122. After the first anti-rotation structure 31 contacts the first limiting structure 122, the first limiting structure 122 can limit the first anti-rotation structure 31 from continuing to move in the first direction, thereby limiting the elastic member 3 from continuing to rotate in the first direction, i.e., the reel 2 cannot drive the elastic member 3 to rotate in the first direction any more. At this time, the elastic member 3 can be stably compressed between the first limiting structure 122 and the reel 2, so that the elastic member 3 is installed more firmly, thereby the elastic member 3 can provide a stable pushing force and has a better axial compression effect on the reel 2.

[0047] In addition, when installing the elastic member 3, only the first anti-rotation structure 31 of the elastic member 3 needs to be placed on the side of the first limiting structure 122 away from the first direction, without the need to deliberately contact the first anti-rotation structure 31 with the first limiting structure 122. During the rotation of the reel 2 in the first direction, the reel 2 drives the first anti-rotation structure 31 to move to abut against the first limiting structure 122, so that the first limiting structure 122 can limit the elastic member 3 from continuing to rotate in the first direction, thereby reducing the installation difficulty of the elastic member 3. Even if the first anti-rotation structure is installed at a wrong position, the reel 2 can still drive the first anti-rotation structure 31 to move to abut against the first limiting structure 122.

[0048] Please refer to Figures 2 to 4 In some embodiments, the first limiting structure 122 includes a plurality of blocking strips 1221, and the plurality of blocking strips 1221 are arranged at intervals along the circumference of the plug-in protrusion 121, and the first anti-rotation structure 31 is located between two adjacent blocking strips 1221. When the first anti-rotation structure 31 cooperates with one of the two adjacent blocking strips 1221, the elastic member 3 is limited from rotating in the first direction. When the first anti-rotation structure 31 cooperates with the other of the two adjacent blocking strips 1221, the elastic member 3 is limited from rotating in the second direction, which is opposite to the first direction.

[0049] It can be understood that the blocking strip 1221 is a long plate structure, and the blocking strip 1221 is arranged vertically on the inner side wall of the cover 12. The plurality of blocking strips 1221 can be arranged at intervals along the circumference of the plug-in protrusion 121, and the first anti-rotation structure 31 can extend between two adjacent blocking strips 1221.

[0050] During the rotation of the reel 2 in the first direction, the first anti-rotation structure 31 also moves in the first direction along the circumference of the plug-in protrusion 121. When the first anti-rotation structure 31 moves to cooperate with one of the two adjacent blocking strips 1221, the blocking strip 1221 can prevent the first anti-rotation structure 31 from continuing to move in the first direction, thereby limiting the elastic member 3 from rotating in the first direction.

[0051] Similarly, in the process that the reel 2 drives the elastic member 3 to rotate in the second direction, the first anti-rotation structure 31 also moves along the circumference of the plug-in protrusion 121 in the second direction, when the first anti-rotation structure 31 moves to cooperate with another one of the two adjacent blocking strips 1221, the other blocking strip 1221 can prevent the first anti-rotation structure 31 from continuing to move in the second direction, thereby limiting the rotation of the elastic member 3 in the second direction.

[0052] Therefore, one of the two adjacent blocking strips 1221 can limit the rotation of the elastic member 3 in the first direction, and the other one of the two adjacent blocking strips 1221 can limit the rotation of the elastic member 3 in the second direction, so that the elastic member 3 cannot rotate in either the forward direction or the reverse direction, thereby further stably assembling the elastic member 3 between the reel 2 and the first limiting structure 122, so that the elastic member 3 can provide a stable pushing force and have a good effect on the axial compression of the reel 2.

[0053] Please refer to Figure 3 In some embodiments, the first anti-rotation structure 31 includes an abutting surface 311 and an inclined surface 312 opposite to the abutting surface 311, the abutting surface 311 is located on the side of the first anti-rotation structure 31 facing the first direction, when the abutting surface 311 cooperates with the first limiting structure 122, it limits the rotation of the elastic member 3 in the first direction, when the inclined surface 312 cooperates with the first limiting structure 122, the inclined surface 312 guides the first anti-rotation structure 31 to pass through the first limiting structure 122 in the second direction, and the second direction is opposite to the first direction.

[0054] Specifically, the end of the elastic member 3 away from the reel 2 extends in a direction away from the reel 2 to form the first anti-rotation structure 31, the first anti-rotation structure 31 is a block structure, and the first anti-rotation structure 31 includes an abutting surface 311 and an inclined surface 312, the abutting surface 311 and the inclined surface 312 are arranged opposite to each other, and the first limiting structure 122 includes a first contact surface and a second contact surface, the first contact surface and the second contact surface are arranged opposite to each other.

[0055] In the process that the reel 2 drives the elastic member 3 to rotate in the first direction, the first anti-rotation structure 31 also moves along the circumference of the plug-in protrusion 121 in the first direction, until the abutting surface 311 abuts against the first contact surface, which can limit the elastic member 3 from continuing to rotate in the first direction, so that the elastic member 3 is stably assembled on the reel 2.

[0056] In the process that the reel 2 drives the elastic member 3 to rotate in the second direction, the first anti-rotation structure 31 also moves along the circumference of the plug-in protrusion 121 in the second direction until the inclined surface 312 contacts the second contact surface, the inclined surface 312 is inclined to the second direction relative to the second contact surface, so that when the inclined surface 312 contacts the second contact surface, the inclined surface 312 can guide the first anti-rotation structure 31 to pass the first limiting structure 122, so that the elastic member 3 can continue to rotate in the second direction, so that the elastic member 3 can rotate in the second direction, and the torque of the elastic member 3 can be prevented from being too large.

[0057] Please refer to Figure 2 、 Figure 4 and Figure 5 In some embodiments, the elastic member 3 is provided with a second anti-rotation structure 32 at one end close to the reel 2, the inner side wall of the cover 12 is provided with a second limiting structure 123, the second limiting structure 123 is located on the circumferential side of the elastic member 3, and the second anti-rotation structure 32 cooperates with the second limiting structure 123 to limit the rotation of the elastic member 3 in the second direction, the second direction is opposite to the first direction.

[0058] It can be understood that the elastic member 3 is provided with the first anti-rotation structure 31 at one end away from the reel 2, the elastic member 3 is provided with the second anti-rotation structure 32 at one end close to the reel 2, and the first anti-rotation structure 31 and the second anti-rotation structure 32 both extend towards the cover 12, the inner side wall of the cover 12 is provided with the second limiting structure 123, the second limiting structure 123 is located on the circumferential side of the elastic member 3, the second limiting structure 123 protrudes relative to the inner side wall of the cover 12, and the second limiting structure 123 and the second anti-rotation structure 32 are arranged along the circumference of the elastic member 3.

[0059] In the process that the reel 2 drives the elastic member 3 to rotate in the second direction, the second anti-rotation structure 32 also moves along the circumference of the plug-in protrusion 121 in the second direction until the second anti-rotation structure 32 contacts and cooperates with the second limiting structure 123, the second anti-rotation structure 32 can limit the elastic member 3 to continue to rotate in the second direction, so that the first anti-rotation structure 31 can limit the elastic member 3 to rotate in the first direction, and the second anti-rotation structure 32 can limit the elastic member 3 to rotate in the second direction, so that the elastic member 3 is more stably compressed between the reel 2 and the cover 12, and the reel 2 is provided with more stable compression force.

[0060] Please refer to Figure 4 In some embodiments, the first limiting structure 122 and the second limiting structure 123 are connected, and the first anti-rotation structure 31 is located on the side of the first limiting structure 122 away from the first direction, and the second anti-rotation structure 32 is located on the side of the second limiting structure 123 away from the second direction.

[0061] Specifically, the first limiting structure 122 is a protrusion extending relative to the inner side wall of the cover 12, the second limiting structure 123 is also a protrusion extending relative to the inner side wall of the cover 12, and the second limiting structure 123 is higher than the first limiting structure 122, which can prevent the first limiting structure 122 from interfering with the second anti-rotation structure 32, and the connection of the first limiting structure 122 and the second limiting structure 123 can increase the structural strength of each other.

[0062] The first anti-rotation structure 31 is arranged on the side of the first limiting structure 122 away from the first direction, which can limit the rotation of the elastic member 3 along the first direction, and the second anti-rotation structure 32 is arranged on the side of the second limiting structure 123 away from the second direction, which can limit the rotation of the elastic member 3 along the second direction. Under the combined limiting action of the first anti-rotation structure 31 and the second anti-rotation structure 32, the elastic member 3 can be fixed between the reel 2 and the cover 12.

[0063] Please refer to Figure 2 and Figure 4 In some embodiments, the second limiting structure 123 includes a plurality of matching plates 1231, the plurality of matching plates 1231 are arranged at intervals along the circumference of the elastic member 3, and the second anti-rotation structure 32 abuts against the matching plate 1231 to limit the rotation of the elastic member 3 along the second direction.

[0064] It can be understood that the matching plate 1231 is a long plate structure, and the matching plate 1231 is connected with the inner side wall of the cover 12, the plurality of matching plates 1231 are arranged at intervals along the circumference of the elastic member 3, and the plurality of matching plates 1231 are arranged one by one with the plurality of blocking strips 1221, each matching plate 1231 is connected with one blocking strip 1221, the second anti-rotation structure 32 can be located between two adjacent matching plates 1231, the matching plate 1231 abuts against the second anti-rotation structure 32, which can limit the rotation of the elastic member 3 along the second direction.

[0065] It should be noted that in the process of rotating the elastic member 3 along the second direction by the reel 2, the second anti-rotation structure 32 will also move along the circumference of the insertion protrusion 121 along the second direction, when the second anti-rotation structure 32 abuts against one matching plate 1231, but the second anti-rotation structure 32 is separated from the abutting state with the matching plate 1231, the second anti-rotation structure 32 continues to rotate along the second direction, and another matching plate 1231 is also located on the movement track of the second anti-rotation structure 32 along the second direction, and the other matching plate 1231 can also abut against the second anti-rotation structure 32 to limit the elastic member 3 from continuing to rotate along the second direction, so that the plurality of matching plates 1231 can better limit the rotation of the elastic member 3 along the second direction.

[0066] Please refer to Figure 4 and Figure 6In some embodiments, the outer circumferential side of the plug protrusion 121 is provided with a plurality of ribs 1211, the plurality of ribs 1211 are arranged at intervals along the circumference of the plug protrusion 121, and the elastic member 3 is sleeved outside the plurality of ribs 1211.

[0067] Optionally, the ribs 1211 can extend along the axial direction of the plug protrusion 121, and the plurality of ribs 1211 are uniformly arranged at intervals along the circumference of the plug protrusion 121. When the elastic member 3 is installed, the elastic member 3 is sleeved outside the plurality of ribs 1211, which can reduce the difficulty of installing the elastic member 3.

[0068] Please refer to Figure 6 In some embodiments, the ribs 1211 have a guide inclined surface 1212 towards one end of the spool 2.

[0069] It should be noted that the side of the guide inclined surface 1212 close to the spool 2 is a first side, the side of the guide inclined surface 1212 opposite to the first side is a second side, and the first side of the guide inclined surface 1212 is inclined relative to the second side towards the direction close to the axis of the plug protrusion 121, so that the guide inclined surface 1212 is inclined as a whole towards the direction close to the axis of the plug protrusion 121. When the elastic member 3 is installed, the plug protrusion 121 extends into the elastic member 3, and one end of the elastic member 3 contacts the guide inclined surface 1212. The guide inclined surface 1212 can guide the elastic member 3 to be sleeved outside the ribs 1211, which facilitates the installation of the elastic member 3.

[0070] Please refer to Figure 4 and Figure 6 In some embodiments, the elastic member 3 can be in interference fit with the ribs 1211, so that the plurality of ribs 1211 contact the elastic member 3, which can make the elastic member 3 more firmly installed and prevent the elastic member 3 from shaking.

[0071] Please refer to Figure 1 and Figure 7 In some embodiments, the spool 2 is a winding spool 21, the carbon tape 4 is wound around the winding spool 21, and the winding spool 21 is used to wind the carbon tape 4.

[0073] Please refer to Figure 1 andFigure 7 In some embodiments, the lower shell 11 has a winding cavity 111 and a tape inlet 113 communicating with the winding cavity 111, and the winding shaft 21 is rotatably installed in the winding cavity 111, and the carbon tape 4 is arranged through the tape inlet 113 and around the winding shaft 21.

[0075] More clearly, the tape inlet 113 and the tape outlet 114 are both arranged towards the space between the first shell part and the second shell part, so that after the carbon tape 4 on the dispensing shaft 22 is stretched out from the tape outlet 114, the carbon tape 4 can be stretched into the winding cavity 111 from the tape inlet 113, and the carbon tape 4 can be arranged around the winding shaft 21, so that the carbon tape 4 can be dispensed while the carbon tape 4 is being used, and after the carbon tape 4 is used up, the used carbon tape 4 can be conveniently collected to the winding shaft 21.

[0076] Please refer to Figure 1 and Figure 7 In some embodiments, the winding shaft 21 is in abutting engagement with the elastic member 3 towards the end surface of the cover 12.

[0077] Optionally, the winding shaft 21 is in abutting engagement with the elastic member 3 towards the end surface of the cover 12, so that the elastic member 3 can be compressed between the winding shaft 21 and the cover 12, so that the elastic member 3 can provide an axial compression force to the winding shaft 21, increase the force required to rotate the winding shaft 21, prevent the winding shaft 21 from rotating due to loosening, and prevent the used carbon tape 4 from being dispensed, thereby preventing the occurrence of blurred printing.
