DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] In order to solve the technical problem of fingers being pinched during the closing process of the printer cover, the utility model provides an anti-finger pinching label printer, which can prevent fingers from being pinched during the closing process of the printer cover.

[0034] It should be noted that the printer described in the present invention is used for but not limited to label printers, etc. For the convenience of explanation, in the present invention, only the label printer is used as an example for explanation. The principles of the printer used in other types of equipment are essentially the same as those used in label printers, so they will not be repeated here.

[0035] See also Figure 1 , Figure 1 This is a structural schematic diagram of an anti-pinch label printer in one embodiment of the present utility model. The anti-pinch label printer includes a printer body 1 and an upper cover 2. The upper cover 2 is rotatably connected to the printer body 1. A resistance is formed between the upper cover 2 and the printer body 1 that can limit the upper cover 2 from rotating in a direction close to the printer body 1.

[0036] Specifically, when the upper cover 2 rotates toward the printer body 1, resistance is formed between the upper cover 2 and the printer body 1. The resistance can limit the upper cover 2 from rotating toward the printer body 1, thereby limiting the rotation of the upper cover 2 and alleviating or preventing the rotating upper cover 2 from hitting or pinching the hand.

[0037] It should be understood that the resistance may only play a buffering role, or may also play a blocking role. Specifically, Figure 1 and Figure 3 As shown, in one embodiment, the resistance can limit the upper cover 2 to a limited position. When the upper cover 2 is in the limited position, an angle is formed with the printer body 1 , and the angle ranges from 15° to 75°.

[0038] In this embodiment, the resistance can limit the upper cover 2 to a limited position. When the upper cover 2 is in the limited position, there is an angle between the upper cover 2 and the printer body 1, which can prevent the rotating upper cover 2 from hitting or pinching the hand.

[0039] like Figure 3 As shown, in one embodiment, the anti-pinch label printer also includes a print head 3 and a print roller 4, the print head 3 is connected to the upper cover 2, the print roller 4 is connected to the printer body 1, and the weight of the print roller 4 is less than the weight of the print head 3.

[0040] It should be understood that the resistance can be generated by the tight fit between the upper cover 2 and the printer body 1, or can be generated by additional structures, such as Figure 5 As shown, in one embodiment, a limiting structure 5 is formed between the printer body 1 and the upper cover 2. During the process of the upper cover 2 rotating toward the printer body 1, the limiting structure 5 has an active state for allowing the upper cover 2 to rotate relative to the printer body 1 and a limiting state for forming resistance to limit the rotation of the upper cover 2 relative to the printer body 1.

[0041] By setting up the limiting structure 5, when the upper cover 2 rotates toward the direction close to the printer body 1, it can rotate to contact and disengage from the limiting structure 5. When the upper cover 2 contacts the limiting structure 5, the resistance is formed. When the upper cover 2 disengages from the limiting structure 5, the upper cover 2 can rotate freely.

[0042] It should be understood that the limiting structure 5 can be a single component or multiple components. Figure 2 As shown, in one embodiment, the limiting structure 5 includes a limiting portion 51 and a damping assembly 52, and the limiting portion 51 and the damping assembly 52 are arranged between the printer body 1 and the upper cover 2, and when the upper cover 2 rotates toward the direction close to the printer body 1, the damping assembly 52 has an active state of being separated from the limiting portion 51 and a limiting state of abutting the limiting portion 51 to form a resistance.

[0043] When the upper cover 2 rotates, the limiting portion 51 is driven to rotate relative to the damping assembly 52. ​​When the limiting portion 51 abuts against the damping assembly 52, the damping assembly 52 can form the resistance. When the limiting portion 51 is separated from the damping assembly 52, the upper cover 2 moves relative to the printer body 1.

[0044] It should be understood that the limiting portion 51 can be connected to the upper cover 2 or the printer body 1, and the damping assembly 52 can be connected to the upper cover 2 or the printer body 1, and the two are respectively arranged on the upper cover 2 and the printer body 1. Specifically, in one embodiment, the limiting portion 51 and the damping assembly 52 are respectively arranged on the printer body 1 and the upper cover 2.

[0045] It should be understood that when the damping assembly 52 is in the limited state, the angle between the upper cover 2 and the printer body 1 can be any angle, specifically, Figure 3 As shown, in one embodiment, when the damping assembly 52 is in the limited state, the angle between the upper cover 2 and the printer body 1 is 60°.

[0046] In this embodiment, when the damping assembly 52 is in the limited position, the angle between the upper cover 2 and the printer body 1 is 60°. At this angle, the angle between the upper cover 2 and the printer body 1 is sufficient to prevent the distance between the upper cover 2 and the printer body 1 from being too close and causing pinching of the hands.

[0047] It should be understood that the damping component 52 can be any structure capable of forming a damping, specifically, Figure 2 As shown, in one embodiment, the damping assembly 52 includes a first elastic member 521, which is partially connected to the printer body 1 and partially extends to be connected to the upper cover 2. The first elastic member 521 can generate an elastic restoring force to offset the rotation of the upper cover 2 in a direction close to the printer body 1.

[0048] When the upper cover 2 rotates toward the direction approaching the printer body 1, the upper cover 2 drives the first elastic member 521 in the damping assembly 52 to rotate. When the rotating damping assembly 52 abuts the limiting portion 51, the first elastic member 521 in the damping assembly 52 is squeezed. The first elastic member 521 is squeezed to form an elastic restoring force, and the elastic restoring force prevents the upper cover 2 from continuing to rotate toward the direction approaching the printer body 1.

[0049] It should be understood that the first elastic member 521 can be a torsion spring, a spring, an elastic block, etc.

[0050] It should be understood that the limiting portion 51 can be embedded in the printer body 1 or set at other parts of the printer body 1, and the damping component 52 and the upper cover 2 can be fixedly connected or connected in other ways, such as Figure 2 As shown, in one embodiment, the printer body 1 is provided with a connecting groove 1a, the limiting portion 51 is connected to the inner wall of the connecting groove 1a, and is partially engaged with the first elastic member 521, and the damping assembly 52 also includes a clamping portion 522, which is connected to the upper cover 2 and is partially engaged with the first elastic member 521.

[0051] By opening a connecting groove 1a in the printer body 1, the limiting portion 51 is embedded in the connecting groove 1a, so that the limiting portion 51 can be embedded in the printer body 1; the damping component 52 is provided with a clamping portion 522, and the clamping portion 522 is clamped with the first elastic portion, thereby achieving the fixation of the first elastic portion relative to the upper cover 2.

[0052] The clamping portion 522 may be a clamping strip, or a protruding structure formed by bending the spring itself.

[0053] It should be understood that the first elastic member 521 and the limiting portion 51 may be connected by abutment or other methods, for example, Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, the first elastic member 521 has first abutting ends 523 formed at both ends respectively, the limiting portion 51 includes a fixed plate 511, two protruding arms 512 and a rotating shaft 513, the fixed plate 511 is connected to the inner wall of the connecting groove 1a, the two protruding arms 512 are arranged at intervals in the connecting groove 1a, and are both connected to the fixed plate 511, the protruding arms 512 are provided with first clamping grooves 512a, the two ends of the rotating shaft 513 are respectively rotatably connected to the two protruding arms 512, the first elastic member 521 is sleeved on the rotating shaft 513, and the two first abutting ends 523 are respectively clamped with the two first clamping grooves 512a.

[0054] In this embodiment, as the first elastic member 521 rotates following the upper cover 2, the two first abutting ends 523 of the first elastic member 521 can be engaged with the first slot 512a of the protruding arm 512. When the upper cover 2 continues to rotate, the first slot 512a can fix the first abutting end 523 of the first elastic member 521, so that the first elastic member 521 produces elastic deformation, forming a resistance to prevent the upper cover 2 from continuing to rotate. At the same time, the position of the first elastic member 521 can be limited by the engagement of the first abutting end 523 with the first slot 512a.

[0055] It should be understood that the first elastic member 521 and the clamping portion 522 on the upper cover 2 can be clamped together by a clamping groove and a buckle, or by two clamping blocks. Specifically, Figure 2 and Figure 5 As shown, in one embodiment, a second abutting end 526 is formed in the middle of the first elastic member 521 , and a receiving groove 522 a is formed in the clamping portion 522 , and the second abutting end 526 is clamped in the receiving groove 522 a .

[0056] A second abutting end 526 is formed in the middle of the first elastic member 521 , and the second abutting end 526 is engaged with the receiving groove 522 a on the engaging portion 522 , thereby achieving engagement between the first elastic member 521 and the engaging portion 522 and limiting movement of the first elastic member 521 relative to the upper cover 2 .

[0057] In order to strengthen the structural strength of the receiving groove 522a, Figure 2As shown, in one embodiment, a plurality of ribs 524 are provided in the receiving groove 522a. The plurality of ribs 524 are evenly arranged along the length direction of the receiving groove 522a and are all connected to the inner wall of the receiving groove 522a.

[0058] By providing the ribs 524 , the ribs 524 can enhance the structural strength of the inner wall of the receiving groove 522 a .

[0059] The upper cover 2 drives the first elastic member 521 to rotate, and when the first elastic member 521 abuts against the protruding arm 512, the first elastic member 521 abuts against the protruding arm 512 and is compressed to form an elastic force. The elastic force may drive the upper cover 2 and the first elastic member 521 to shake up and down relative to the printer body 1, increasing the risk of hitting hands by shaking up and down. Figure 2 As shown, in one embodiment, the damping assembly 52 also includes two abutment portions 525, and the abutment portions 525 are arranged in a one-to-one correspondence with the protruding arms 512. The abutment portions 525 are arranged relative to the first card slot 512a and are connected to the inner wall of the connecting slot 1a, and the abutment portions 525 abut against the first abutment end 523, for limiting the first abutment end 523 from sliding out along the opening of the first card slot 512a.

[0060] When the upper cover 2 drives the first elastic member 521 to rotate, and when the first abutting end 523 of the first elastic member 521 hits the inner wall of the first card slot 512a, the abutting portion 525 abuts against the first abutting end 523, which can limit the first abutting end 523 from sliding out along the opening of the first card slot 512a, and limit the first abutting end 523, the first elastic member 521 and the upper cover 2 from shaking up and down relative to the printer body 1, so as to prevent the upper cover 2 from shaking up and down and hitting the hands.

[0061] In order to facilitate the first abutting end 523 to slide into the first slot 512a, as shown in FIG. Figure 2 As shown, in one embodiment, an opening for the first abutting end 523 to slide into is formed between the abutting portion 525 and the protruding arm 512, and the size of the opening gradually decreases in a direction approaching the first locking groove 512a.

[0062] When the first abutting end 523 rotates along with the upper cover 2, the first abutting end 523 first rotates and slides into the opening, and slides into the first slot 512a under the guidance of the opening, and abuts the inner wall of the first slot 512a and the abutting portion 525. The opening can guide the first abutting end 523 to slide into the first slot 512a, preventing the first abutting end 523 from being blocked by the end of the abutting portion 525.

[0063] In order to realize the connection between the print head 3 and the upper cover 2, as shown in FIG. Figure 6As shown, in one embodiment, the anti-pinch label printer also includes a mounting structure 6, which is connected to the upper cover 2, and one end of the mounting structure 6 is connected to the print head 3, and the other end is connected to the circuit board 7.

[0064] By providing a mounting structure 6 , the mounting structure 6 is used to fix the print head 3 to the upper cover 2 .

[0065] It should be understood that the print head 3 and the mounting structure 6 can be fixedly connected or movably connected. Figure 6 As shown, in one embodiment, the mounting structure 6 includes a mounting portion 61, at least one first protrusion 62, a second protrusion 63 and at least one second elastic member 64, the mounting portion 61 is connected to the upper cover 2 and the circuit board 7, the second protrusion 63 is connected to the print head 3, the second elastic member 64 is arranged between the first protrusion 62 and the second protrusion 63, and one end of the second elastic member 64 is connected to the first protrusion 62 and the other end is connected to the second protrusion 63, so that the print head 3 can slide close to or away from the circuit board 7.

[0066] When the upper cover 2 is closed, the print roller 4 on the printer body 1 pushes the print head 3 to slide in the direction of embedding into the upper cover 2. The print head 3 drives the second protrusion 63 to slide and squeezes the second elastic member 64. The second elastic member 64 provides an elastic reset force for the print head 3 to slide back, so that the print head 3 fits the print roller 4. At the same time, the print head 3 moves, so that paper can be inserted between the print head 3 and the print roller 4, allowing paper to pass between the print head 3 and the print roller 4.

[0067] It should be understood that the mounting portion 61 and the circuit board 7 may be directly connected or indirectly connected.

[0068] In order to prevent the upper cover 2 in the open state from automatically falling down, in one embodiment, as shown in FIG. Figure 1 and Figure 3 As shown, when the upper cover 2 increases in opening angle, it can rotate to abut against the printer body 1 , and at this time, the center of gravity of the upper cover 2 is located on the side where the rotation axis of the upper cover 2 deviates from the printer body 1 .

[0069] When the upper cover 2 is opened, the bottom of the upper cover 2 can rotate to abut the outer wall of the printer body 1, and the upper cover 2 is engaged with the printer body 1. At this time, since the center of gravity of the upper cover 2 is located on the side of the rotation axis of the upper cover 2 that deviates from the printer body 1, the upper cover 2 can be maintained at an open angle under the action of gravity, reducing the risk of the upper cover 2 falling down.
