Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a printer cover opening structure. Background Art

[0002] In the field of printers, achieving a stable and reliable connection between various components is the key to ensuring efficient and stable operation of the printer. In traditional printer connection technology, the torsion force of the torsion spring is often used to drive the transmission rod to drive the buckle block to engage with the buckle groove to achieve the clamping and fixing of the upper cover and the base of the printer. Although this connection method ensures the stability of the connection to a certain extent, during the installation process, the torsion spring needs to be inserted into the corresponding pin shaft so that the torsion spring abuts against the transmission rod to achieve transmission. Since the installation space in some small printers is small, it is not easy to install the torsion spring, and the installation time is long, which increases the difficulty and time of printer assembly. For this reason, we provide a printer cover opening structure to solve the above problems. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a printer cover opening structure.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A printer cover opening structure comprises a base and an upper cover which are rotatably connected to each other, hooks are rotatably installed on both sides of the installation cavity of the base, blocks adapted to the hooks are arranged on both sides of the interior of the installation cavity of the upper cover, a driving component for driving the hooks to rotate and disengage from the blocks is also installed on the base, an abutment block is fixedly arranged on the base on one side of each hook, and a compression spring is arranged on the side of the abutment block close to the hook to drive the hook to rotate and engage with the block.

[0006] Preferably, the driving assembly includes a transmission rod installed between the two hooks, and a button installed on the end surface of the base, and the hook is driven to rotate and disengage from the block through the transmission rod by pressing the button.

[0007] Preferably, the hook includes a hook body rotatably installed in the base mounting cavity, the hook body is composed of a transmission part and a clamping part, a rotation hole is provided between the transmission part and the clamping part, the rotation hole and the base mounting cavity are rotationally connected through a first pin shaft, and a clamping groove adapted to the clamping block is provided at the bottom of the clamping part.

[0008] Preferably, a special-shaped hole is provided on the transmission part, and special-shaped shafts matching the special-shaped hole are provided at both ends of the transmission rod.

[0009] Preferably, a protrusion adapted to the compression spring is provided on the transmission part in a direction close to the abutment block, and an end of the compression spring is sleeved on an outer surface of the protrusion.

[0010] Preferably, the end surface of the abutment block close to the hook is provided with a groove adapted to the compression spring.

[0011] Preferably, a second pin is provided at the rotation position of the base and the upper cover, and the base and the upper cover are rotationally connected via the second pin.

[0012] The utility model has the following advantages:

[0013] 1. The utility model drives the hook to rotate through the elastic force of the compression spring, so that the hook and the card block are engaged to achieve fixation between the base and the upper cover. Compared with the existing method of using a torsion spring to drive the hook and the card block to engage and fix, it only needs to install the compression spring between the hook and the abutment block, and there is no need to install the corresponding pin shaft. The elastic force of the compression spring is used to drive the hook and the card block to engage and achieve installation.

[0014] 2. When the base and the upper cover need to be opened, the user only needs to press the button to transfer the pressing force to the transmission rod and cause the transmission rod to rotate at a certain angle. Since the transmission rod is installed between two hooks, the transmission rod will also drive the hook to rotate at a certain angle when it rotates, so that the hook is separated from the card block to unlock, and then the base and the upper cover are separated to realize the cover opening function.

[0015] 3. The utility model can realize the transmission of force from the pressing force of the key through the clamping connection between the special-shaped shaft and the special-shaped hole through the cooperation between the special-shaped shaft and the special-shaped hole.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 — Figure 5 The embodiment shown.

[0025] A printer cover opening structure comprises a base 1 and an upper cover 2 which are rotatably connected to each other, hooks 3 are rotatably installed on both sides of the installation cavity of the base 1, and blocks 5 adapted to the hooks 3 are arranged on both sides of the interior of the installation cavity of the upper cover 2. A driving component 4 for driving the hooks 3 to rotate and disengage from the blocks 5 is also installed on the base 1, and an abutment block 7 is fixedly arranged on the base 1 on one side of each hook 3, and a compression spring 6 for driving the hook 3 to rotate and engage with the blocks 5 is arranged on the side of the abutment block 7 close to the hook 3.

[0026] See also Figures 1 to 5As shown, when installation is required, it is only necessary to install the compression spring 6 to the abutting end of the hook 3 and the abutting end of the abutting block 7. Under the elastic force of the compression spring 6, the hook 3 is driven to rotate a certain angle so as to be engaged with the block 5, thereby achieving closure between the base 1 and the upper cover 2; compared with the existing use of a torsion spring to drive the hook 3 and the block 5 to be engaged, the present application only needs to install the compression spring 6 between the hook 3 and the abutting block 7, and does not require a corresponding installation shaft for the torsion spring sleeve. The installation is simple and does not require a large space, which greatly improves the installation efficiency.

[0027] In this embodiment, when the base 1 and the upper cover 2 need to be opened, it is only necessary to drive the hook 3 to overcome the elastic force of the compression spring 6 and rotate through the driving component 4, so that the hook 3 is disengaged from the card block 5, thereby realizing the unlocking state of the released connection, and then the base 1 and the upper cover 2 can be separated and opened; when the base 1 and the upper cover 2 need to be closed, it is only necessary to move the base 1 and the upper cover 2 closer to each other, so that the hook 3 and the card block 5 are buckled, and under the elastic force of the compression spring 6, the hook 3 and the card block 5 are always in a buckled state, so that the base 1 and the upper cover 2 are closed.

[0028] The driving assembly 4 includes a transmission rod 41 installed between the two hooks 3 and a button 42 installed on the end surface of the base 1. By pressing the button 42, the transmission rod 41 drives the hook 3 to rotate and disengage from the block 5.

[0029] See also Figures 1 to 3 As shown, when the base 1 and the upper cover 2 need to be separated and unlocked, the button 42 is first pressed in the direction of the transmission rod 41, thereby driving the transmission rod 41 to rotate at a certain angle. Since the transmission rod 41 is installed between the two hooks 3 and is connected to the two hooks 3 for transmission, that is, when the transmission rod 41 rotates, the hook 3 will also be driven to rotate at a certain angle. During the rotation of the hook 3, the elastic force of the compression spring 6 is overcome to separate from the card block 5, thereby realizing the unlocking and separation of the base 1 and the upper cover 2. After the separation is completed, the elastic force of the compression spring 6 drives the hook 3 and the transmission rod 41 to return to the initial position, thereby also driving the button 42 to return to the initial position.

[0030] The hook 3 includes a hook body 31 rotatably installed in the mounting cavity of the base 1, and the hook body 31 is composed of a transmission part 32 and a clamping part 33. A rotation hole 34 is provided between the transmission part 32 and the clamping part 33. The rotation hole 34 is rotatably connected to the mounting cavity of the base 1 through a first pin shaft 8. A clamping groove 35 adapted to the clamping block 5 is provided at the bottom of the clamping part 33.

[0031] In this embodiment, the bottom surface of the snap-in portion 33 is an inclined surface (not marked in the figure). This design is that when the slot 35 needs to be snapped with the block 5, the upper cover 2 drives the block 5 to move toward the snap-in portion 33, and it is necessary to guide through the inclined surface so that the slot 35 and the block 5 can be combined to achieve snap-in fixation.

[0032] See also Figures 1 to 5 As shown, during installation, the first pin 8 is inserted into the rotating hole 34 and the corresponding mounting hole in the upper cover 2 to complete the installation of the hook body 31, and the transmission rod 41 is connected to the transmission part 32, that is, when the transmission rod 41 rotates at a certain angle, the transmission part 32 also rotates. When the base 1 and the upper cover 2 are separated and unlocked, the force from the button 42 is first transmitted to the transmission rod 41, so that the transmission rod 41 and the transmission part 32 rotate at a certain angle with the rotating hole 34 as the rotation axis. Since the rotating hole 34 is located between the transmission part 32 and the clamping part 33, the clamping part 33 moves away from the clamping block 5, so that the clamping slot 35 is separated from the clamping block 5, and unlocking is achieved, so that the base 1 and the upper cover 2 can be separated and opened.

[0033] When the base 1 and the upper cover 2 need to be closed, the upper cover 2 first drives the card block 5 to move toward the base 1. During the buckling process, the elastic force of the compression spring 6 is overcome to cause the clamping portion 33 and the transmission portion 32 to rotate at a certain angle. Specifically, when the clamping portion 33 contacts the card block 5, it first drives the card slot 35 to overcome the elastic force of the compression spring 6 and move away from the card block 5. Next, after the card slot 35 is buckled with the card block 5, the elastic force of the compression spring 6 drives the clamping portion 33 to move toward the card block 5, thereby maintaining the card slot 35 in a state of being always engaged with the card block 5, so that the card slot 35 is combined with the card block 5 to complete the buckling and fixation.

[0034] The transmission part 32 is provided with a special-shaped hole 36 , and both ends of the transmission rod 41 are provided with special-shaped shafts 11 adapted to the special-shaped hole 36 .

[0035] See also Figures 3 to 5 As shown, firstly, in order to be able to transmit the power from the transmission rod 41 to the transmission part 32, so that the transmission rod 41 and the transmission part 32 are connected and transmitted, specifically, the transmission of the force from the transmission rod 41 is achieved by the connection between the special-shaped hole 36 and the special-shaped shaft 11. The shapes of the special-shaped hole 36 and the special-shaped shaft 11 can be triangular, rectangular, semicircular, gear-shaped, etc. In practice, the shapes of the two include but are not limited to the shapes exemplified above, and can be designed to suit the needs, and there is no limitation here.

[0036] The transmission part 32 is provided with a protrusion 10 adapted to the compression spring 6 in a direction close to the abutment block 7 , and an end of the compression spring 6 is sleeved on an outer surface of the protrusion 10 .

[0037] The end surface of the abutment block 7 close to the hook 3 is provided with a groove 12 adapted to the compression spring 6 .

[0038] See also Figures 3 to 5 As shown, in order to prevent the compression spring 6 between the hook 3 and the abutment block 7 from moving in position, a groove 12 is opened on the side of the abutment block 7 to accommodate one end of the compression spring 6, and a protrusion 10 is set on the end surface of the transmission part 32 close to the abutment block 7 for the other end of the compression spring 6 to be sleeved. Under the limitation of the groove 12 and the protrusion 10, the compression spring 6 is prevented from detaching, so that the compression spring 6 is always located between the abutment block 7 and the transmission part 32.

[0039] The base 1 and the upper cover 2 are provided with a second pin shaft 9 at the rotational position, and the base 1 and the upper cover 2 are rotationally connected via the second pin shaft 9 .

[0040] The working process of the utility model is as follows: when it is necessary to separate and open the base 1 and the upper cover 2, first press the button 42 to drive the transmission rod 41 to rotate a certain angle with the rotating hole 34 as the rotating axis. Since the transmission rod 41 is connected to the transmission part 32 for transmission, the transmission rod 41 also drives the transmission part 32 to rotate while rotating, thereby driving the card slot 35 at the position of the card connection part 33 to separate from the card block 5. At this time, there is no longer a card relay between the card slot 35 and the card block 5 between the base 1 and the upper cover 2, so the unlocking is achieved so that the base 1 and the upper cover 2 can be separated and opened.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
