[0002] Labels refer to the text, graphic symbols and all explanatory materials on a product. Labels are widely used in supermarket retail, industrial production, express delivery, clothing, office management and other scenarios, such as price tags, product description labels, shelf labels, barcode labels, clothing labels, file labels, archive labels, various items and stationery labels, express delivery labels, etc. Users can use a label printer to print labels. The label printer includes a rubber roller and a print head. A printing channel is formed between the rubber roller and the print head. The printing channel is used for the material to be printed to pass through so that the material is printed with a label when passing through the printing channel. In order to make the printing of materials more stable, a positioning structure for positioning the material is usually set on the printer.

[0003] However, existing label printers still have defects. For example, the positioning structure does not have a structure to prevent the positioning head from falling off, which causes the positioning head to fall off easily due to accidental touch by the staff during use, thereby affecting the printing efficiency. Utility Model Content

[0004] In view of this, it is necessary to provide a tube pressing block structure and a printer to solve the technical problem that the positioning structure of the printer in the prior art has no structure to prevent the positioning head from falling off, resulting in the positioning head being easily accidentally touched and falling off by the staff during use, thereby affecting the printing efficiency.

[0005] In order to achieve the above technical purpose, the technical solution of the utility model provides a pipe pressing block structure, including:

[0006] A fixed bracket having a limiting protrusion; and

[0007] The rotating pressure block includes a pressing tube part and two elastic arms. The two elastic arms are arranged at intervals and one end of each is connected to the pressing tube part, and the other end of each is rotatably connected to the fixed bracket. The two elastic arms can be deformed in a direction approaching each other to detach from the fixed bracket. The two elastic arms have a first state of rotating on both sides of the limiting protrusion, at which time the limiting protrusion restricts the two elastic arms from approaching each other. The two elastic arms also have a second state of rotating to detach from the limiting protrusion.

[0008] Furthermore, the rotating pressure block also includes a torsion spring, and the two elastic arms are respectively a first elastic arm and a second elastic arm. The torsion spring connects the first elastic arm and / or the second elastic arm, and can drive the first elastic arm and the second elastic arm to rotate to the first state through elastic force.

[0009] Furthermore, the fixed bracket is provided with a accommodating groove, and the two opposite groove walls of the accommodating groove are provided with rotation grooves, and the first elastic arm and the second elastic arm are provided with rotation columns on the opposite sides thereof, and are both rotatably arranged in the corresponding rotation grooves through the rotation columns; when the first elastic arm and the second elastic arm are misaligned with the limiting protrusion, the first elastic arm and the second elastic arm can be deformed and approach each other so that the rotation column can be separated from the rotation groove.

[0010] Furthermore, the fixing bracket is provided with a guide slope, the guide slope is connected with the rotation groove, and the rotation column can slide along the guide slope to be inserted into the rotation groove.

[0011] Furthermore, one end of the first elastic arm and the second elastic arm away from the tube pressing portion has a limiting portion, and the limiting portion can limit the rotating pressing block from excessive rotation.

[0012] Furthermore, one end of the tube pressing portion away from the first elastic arm has a tube pressing surface, and the tube pressing surface is an arc surface or an inclined surface.

[0013] Furthermore, the rotating pressing block also includes a guide shaft arranged on the tube pressing part, and the guide shaft is used to move along the guide groove of the printer during the tube pressing process.

[0014] Furthermore, the guide shaft passes through the pressing tube portion along a first direction and extends from both sides of the pressing tube portion, and the first direction is parallel to the rotation axis of the rotating pressing block.

[0015] Furthermore, the first elastic arm, the second elastic arm and the pressing tube portion are an integrally formed structure.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the fixed bracket of the tube pressing block structure provided by the utility model can be used for rotation installation on the printer for use. When it is necessary to position the material of the printing channel of the printer, the fixed bracket can be rotated so that the tube pressing part of the rotating pressing block presses the material to position the material, and at the same time drives the torsion spring to accumulate elastic force. When it is not necessary to position the material, the fixed bracket can be rotated to separate the tube pressing part from the material, and the torsion spring releases the elastic force to drive the rotating pressing block to rotate and reset. When the rotating pressing block does not press the material, the torsion spring can drive the rotating pressing block to rotate through the elastic force so that the limiting protrusion is located between the first elastic arm and the second elastic arm, and at this time the first elastic arm and the second elastic arm cannot be relatively close to each other and separate from the fixed bracket. When it is necessary to disassemble the rotating pressing block, the rotating pressing block can be first driven to rotate until the first elastic arm and the second elastic arm are both misaligned with the limiting protrusion, and at this time the limiting protrusion no longer plays a limiting role, and the first elastic arm and the second elastic arm can be close to each other through deformation to separate from the fixed bracket. Therefore, the rotating pressing block will basically not separate from the fixed bracket in a natural state, and it is stable to use. When the rotating pressing block needs to be disassembled, the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0024] refer to Figure 1 The utility model provides a tube pressing block structure 100, which can be rotatably installed on a printer and is mainly used to press the material in the printing channel of the printer to prevent the material from shaking during the printing process and affecting the printing effect.

[0025] refer to Figure 1 and Figure 2 The tube pressing block structure 100 includes a fixed bracket 2 and a rotating block 1, and the rotating block 1 is rotatably connected to the fixed bracket 2. The tube pressing block structure 100 is rotatably arranged on the printer through the fixed bracket 2, so that the fixed bracket 2 can drive the rotating block to press the material when rotating to position the material.

[0026] The fixed bracket 2 has a limiting protrusion 21, and the rotating pressing block 1 includes a pressing tube portion 11, a torsion spring 12, a first elastic arm 13 and a second elastic arm 14. The first elastic arm 13 and the second elastic arm 14 are arranged at intervals and one end of each is connected to the pressing tube portion 11. The rotating pressing block 1 is rotatably connected to the fixed bracket 2 through the torsion spring 12. The torsion spring 12 can drive the rotating pressing block 1 to rotate through elastic force so that the limiting protrusion 21 is located between the first elastic arm 13 and the second elastic arm 14. At this time, the first elastic arm 13 and the second elastic arm 14 are in the first state. The rotating pressing block 1 can rotate under the action of an external force to overcome the elastic force of the torsion spring 12, so that the first elastic arm 13 and the second elastic arm 14 are both misaligned with the limiting protrusion 21. At this time, the first elastic arm 13 and the second elastic arm 14 are in the second state.

[0027] The fixed bracket 2 of the tube pressing block structure 100 provided by the utility model can be used for rotation installation on the printer for use. When it is necessary to position the material in the printing channel of the printer, the fixed bracket 2 can be rotated so that the tube pressing part 11 of the rotating pressing block 1 presses against the material to position the material, and at the same time drives the torsion spring 12 to accumulate elastic force. When it is not necessary to position the material, the fixed bracket 2 can be rotated to separate the tube pressing part 11 from the material, and the torsion spring 12 releases the elastic force to drive the rotating pressing block 1 to rotate and reset. When the rotating pressing block 1 does not press against the material, the torsion spring 12 can drive the rotating pressing block 1 to rotate through the elastic force, so that the limiting protrusion 21 is located between the first elastic arm 13 and the second elastic arm 14. At this time, the first elastic arm 13 and the second elastic arm 14 cannot be relatively close to each other and separate from the fixed bracket 2. When the rotating pressing block 1 needs to be disassembled, the rotating pressing block 1 can be first rotated until the first elastic arm 13 and the second elastic arm 14 are misaligned with the limiting protrusion 21. At this time, the limiting protrusion 21 no longer has a limiting effect, and the first elastic arm 13 and the second elastic arm 14 can be deformed to approach each other to separate from the fixed bracket 2. Therefore, the rotating pressing block 1 will basically not separate from the fixed bracket 2 in a natural state, and is stable to use. When the rotating pressing block 1 needs to be disassembled, the operation is simple.

[0028] The connection method between the first elastic arm 13, the second elastic arm 14 and the pressing tube portion 11 is not limited, and can be an integrally formed structure or a detachable connection. Figure 2In the illustrated embodiment, the first elastic arm 13, the second elastic arm 14 and the pressing tube portion 11 are an integrally formed structure, so that the first elastic arm 13, the second elastic arm 14 and the pressing tube portion 11 are stably connected. It should be noted that the first elastic arm 13 and the second elastic arm 14 are made of elastic material, such as elastic plastic, so that the first elastic arm 13 and the second elastic arm 14 have strong elastic deformation ability, so that the first elastic arm 13 and the second elastic arm 14 are easy to detach from the fixed bracket 2 through elastic deformation.

[0029] refer to Figure 2 and Figure 4 The first elastic arm 13 and the second elastic arm 14 are arranged at intervals, which can also be understood as a avoidance groove 50 is opened in the middle of the rotating pressing block 1. When the first elastic arm 13 and the second elastic arm 14 are subjected to external force, they can move toward the avoidance groove 50. When the external force is removed, the first elastic arm 13 and the second elastic arm 14 will elastically return to their original position.

[0030] There are many ways to rotatably connect the fixed bracket 2 and the rotating pressing block 1. For example, the fixed bracket 2 can be rotatably connected to the pressing tube portion 11 of the rotating pressing block 1, and can also be rotatably connected to the first elastic arm 13 and the second elastic arm 14. In one embodiment, the fixed bracket 2 is provided with a receiving groove 22, and the two opposite groove walls of the receiving groove 22 are provided with rotation grooves (not shown in the figure), and the first elastic arm 13 and the second elastic arm 14 are provided with rotation columns 15 on the opposite sides, and are both rotatably arranged in the corresponding rotation grooves through the rotation columns 15, so that the rotating pressing block 1 is rotatably connected to the fixed bracket 2.

[0031] During the rotation of the rotating pressure block 1, the first elastic arm 13 and the second elastic arm 14 can be driven to rotate to the two sides of the limiting protrusion 21 (it can also be understood that the limiting protrusion 21 is located between the two elastic arms), and the first elastic arm 13 and the second elastic arm 14 can also be driven to be misaligned with the limiting protrusion 21 (it can also be understood that the limiting protrusion 21 is not located between the two elastic arms).

[0032] refer to Figure 3 and Figure 4 When the limiting protrusion 21 is located between the first elastic arm 13 and the second elastic arm 14, the limiting protrusion 21 can prevent (limit) the first elastic arm 13 and the second elastic arm 14 from approaching each other, thereby preventing the rotating columns 15 of the two elastic arms from detaching from the corresponding rotating grooves, so that the rotating pressure block 1 is stably connected to the fixed bracket 2 and is not easy to fall off.

[0033] refer to Figure 1 and Figure 2When the first elastic arm 13 and the second elastic arm 14 are both misaligned with the limiting protrusion 21, the limiting protrusion 21 does not limit the two elastic arms, and the first elastic arm 13 and the second elastic arm 14 can be deformed closer to each other when subjected to external force, so as to drive the two rotating columns 15 to disengage from the corresponding rotating grooves, thereby completing the disassembly of the rotating pressing block 1 and the fixed bracket 2. Specifically, the staff can first manually drive the rotating pressing block 1 to rotate to the position where the two elastic arms are misaligned with the limiting protrusion 21, and then use two fingers to pinch the first elastic arm 13 and the second elastic arm 14, drive the first elastic arm 13 and the second elastic arm 14 to deform and approach each other, and complete the disassembly. At this time, the rotating pressing block 1 can also be installed in the fixed bracket 2.

[0034] In the natural state, the torsion spring 12 drives the rotating pressure block 1 to rotate to the position where the first elastic arm 13 and the second elastic arm 14 are located on both sides of the limiting protrusion 21 through elastic force. At this time, the two elastic arms of the rotating pressure block 1 will not deform and detach from the fixed bracket 2 even when subjected to external force.

[0035] refer to Figure 2 The number of torsion springs 12 is not limited, and one or two may be provided. In one embodiment, the number of torsion springs 12 is one, and the torsion spring 12 is sleeved on one of the rotating posts 15. The torsion spring 12 drives the other rotating post 15 to be closely attached to the corresponding rotating groove through its axial elastic force, so that the rotating pressing block 1 can be stably connected to the fixed bracket 2 in a natural state and is not easy to fall off.

[0036] refer to Figure 2 In one embodiment, the fixed bracket 2 is provided with a guide slope 16, and the guide slope 16 is connected with the rotation groove. When the rotating pressing block 1 is inserted into the rotation groove, the rotating column 15 of the rotating pressing block 1 can slide along the guide slope 16 to be inserted into the rotation groove, so that the rotating pressing block 1 can be smoothly inserted into the rotation groove, and the installation is fast and convenient.

[0037] refer to Figure 2 In one embodiment, the first elastic arm 13 and the second elastic arm 14 have a limiting portion 17 at one end away from the pressing tube portion 11, and the limiting portion 17 can limit the excessive rotation of the rotating pressing block 1, so that in a natural state, the rotating pressing block 1 can rotate stably so that the first elastic arm 13 and the second elastic arm 14 are located on both sides of the limiting protrusion 21, and the rotating pressing block 1 is in a state that cannot be disassembled.

[0038] refer to Figure 2 In one embodiment, the end of the pressing tube portion 11 away from the first elastic arm 13 has a pressing tube surface 18, and the pressing tube surface 18 is an arc surface or an inclined surface. When the rotating pressing block 1 presses the material, the rotating pressing block 1 presses the material through its pressing tube surface 18, and the pressing tube surface 18 with an arc surface or an inclined surface presses the material, which is not easy to damage the material.

[0039] refer to Figure 4In one embodiment, the rotating pressing block 1 also includes a guide shaft 19 arranged on the tube pressing part 11, and the printer is provided with a guide groove on the path of movement of the guide shaft 19, so that when the rotating pressing block 1 is in the process of pressing the material, the guide shaft 19 can move along the guide groove of the printer, so that the tube pressing surface 18 can stably press the material along a fixed route, which is beneficial to improve the stability of material positioning.

[0040] The setting structure of the guide shaft 19 is not limited. In one embodiment, the guide shaft 19 passes through the pressing tube part 11 along a first direction and extends from both sides of the pressing tube part 11. The first direction is parallel to the rotation axis of the rotating pressing block 1. The printer is provided with two guide grooves. When the rotating pressing block 1 is pressing the material, the guide shafts 19 extending from both sides of the pressing tube part 11 can respectively pass through the two guide grooves and move along a fixed path. In another embodiment, two guide shafts 19 can also be provided. The two guide shafts can be respectively provided at both ends of the pressing tube part 11, which can also achieve the same technical effect.

[0041] refer to Figure 5 The utility model further provides a printer 101, which includes a machine body 3, a top cover 4 and the above-mentioned tube pressing block structure 100, wherein the top cover 4 is rotatably connected to the machine body 3, and the tube pressing block structure 100 is connected to the top cover 4 through a fixed bracket 2. The machine body 3 is provided with a printing channel 31, and when the top cover 4 is in the process of being closed, the top cover 4 can drive the tube pressing block structure 100 to move, so that the tube pressing surface 18 of the rotating block 1 presses against the material located in the printing channel 31.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
