Description

Technical Field

[0001] The present invention belongs to the technical field of scanning pens, and specifically relates to a mounting rack for a scanning and translating pen. Background Technique

[0002] A scanning and translating pen is a device that uses scanning technology (usually infrared scanning) to scan printed characters into the pen, which are then recognized through OCR inside the pen, and translated through the built-in translation software inside the pen. (Nowadays, scanning pens not only have a simple translation function, but also include an extraction function).

[0003] Currently, after an operator uses a scanning and translating pen, they often need to store the scanning pen. The existing method of storing the scanning pen is to use a pen cap to clip onto the tip of the scanning and translating pen to protect the scanning pen. Then, the operator places the scanning and translating pen with the pen cap in a pen holder to store the scanning and translating pen. However, since the volume of the scanning and translating pen is usually larger than that of an ordinary pen, it takes up a lot of space inside the pen holder, which not only affects the placement of the scanning pen but also makes it inconvenient to place other pens in the pen holder. Therefore, a mounting rack for a scanning and translating pen is proposed to solve the problems raised in the background technique. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The present invention cooperates with the structures such as the movable frame, the protective cover, the card block and the first spring sheet, so that the device has the function of conveniently storing the scanning translation pen. The bottom of the scanning translation pen body is inserted into the inner cavity of the protective cover, and the top of the scanning translation pen body is pressed and contacted with the bottom of the pressure plate. Then the operator presses the movable frame downward, so that the movable frame drives the scanning translation pen body to move downward. At this time, the telescopic rod structure is in a compressed state, and the bottom of the movable frame will squeeze the card block at the inclined surface close to one side of the movable frame, so that the card block moves to the side away from the movable frame. When the card block is completely located in the inner cavity of the protective shell, the movable frame continues to move downward. When the inner cavity of the middle part of the movable frame close to one side of the card block is at the same height as the outer surface of the card block, due to the elastic force of the first spring sheet, the card block will be inserted into the middle part of the inner cavity of the movable frame close to the card block, thereby fixing the movable frame. At this time, the scanning translation pen body will be inside the protective shell, which is convenient for the operator to protect and store the scanning translation pen body.

[0016] The present invention cooperates with the structures such as the T-shaped block, the second spring sheet, the L-shaped spring sheet and the inclined plate, so that the device has the function of facilitating the removal and use of the scanning translation pen. By pressing the T-shaped block downward, the bottom of the T-shaped block will squeeze the oblique surface of the card block located in the inner cavity of the protective shell, so that the end of the card block located in the inner cavity of the movable frame moves toward the side away from the movable frame, so that the card block releases the clamping connection with the movable frame. At this time, due to the tension of the second tension spring, the inner rod will move upward, and then drive the movable frame and the scanning translation pen body to move upward and then separate from the inner cavity of the movable frame. Then, the operator presses the inclined plate toward the side close to the scanning translation pen body, which will cause the top of the inclined plate to rotate counterclockwise with the bottom of the inclined plate and the hinge of the movable frame as the axis, so that the top of the inclined plate squeezes one side of the scanning translation pen body, so that the scanning translation pen body is separated from the inside of the movable frame, thereby facilitating the operator to take out the scanning translation pen body.

[0017] The present invention achieves simple fixing and buffering of the scanning translation pen by the coordination among the first tension spring, the pressure plate and the telescopic rod structure. The arc-shaped part at the bottom of the pressure plate is squeezed by the top of the scanning translation pen body, thereby compressing the first tension spring. When the top of the charging port is in full contact with the bottom of the magnetic charging head, the scanning translation pen body is fixed. When the T-shaped block is pressed to release the clamping block from the movable frame, the scanning translation pen body will have an upward inertia when the telescopic rod structure bounces up to the top. At this time, the first tension spring will have a good buffering effect on the upward inertia of the scanning translation pen body, thereby preventing damage to the scanning translation pen body and facilitating the use of the operator.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Such as Figures 1 to 6As shown in the figure, the present invention provides a mounting bracket for a scanning translation pen, including a protective case 1 and a scanning translation pen body 7. Inside the protective case 1, there are movably connected an activity frame 2, a clamping block 9, and a T-shaped block 11. At the front and rear ends of the bottom of the inner cavity of the activity frame 2, there are fixedly connected fixing blocks 3. Between the front and rear fixing blocks 3, there is a hinged protective cover 4. At equal intervals on the top of the inner cavity of the activity frame 2, there are fixedly connected first tension springs 5. The bottom of the first tension spring 5 is fixedly connected with a pressing plate 6. At the front and rear ends on one side of the inner cavity of the activity frame 2, there are fixedly connected soft pads 8. On the side of the clamping block 9 away from the activity frame 2, there is fixedly connected a first spring piece 10. On the lower surface of the middle part of the T-shaped block 11 away from the side of the activity frame 2, there is fixedly connected a second spring piece 12. At the bottom of the inner cavity of the protective case 1, there is fixedly connected a telescopic rod structure 13 located at the front end and the rear end of the activity frame 2; by inserting the bottom of the scanning translation pen body 7 into the inner cavity of the protective cover 4, and at the same time, the top of the scanning translation pen body 7 is in pressing contact with the bottom of the pressing plate 6. Then, the operator presses the activity frame 2 downward, so that the activity frame 2 drives the scanning translation pen body 7 to move downward. At this time, the telescopic rod structure 13 is in a compressed state. At the same time, the bottom of the activity frame 2 will press the inclined surface on the side of the clamping block 9 close to the activity frame 2, so that the clamping block 9 moves away from the activity frame 2. When the clamping block 9 is entirely inside the protective case 1, at this time, the activity frame 2 continues to move downward. When the inner cavity on the side of the activity frame 2 close to the clamping block 9 in the middle is at the same height as the outer surface of the clamping block 9, at this time, due to the elastic force of the first spring piece 10, the clamping block 9 will be clamped into the middle of the inner cavity on the side of the activity frame 2 close to the clamping block 9, thus realizing the fixation of the activity frame 2. At this time, the scanning translation pen body 7 will be inside the protective case 1, which facilitates the operator to protect and store the scanning translation pen body 7 for use.

[0027] As Figure 3 , Figure 5 , Figure 6As shown, the telescopic rod structure 13 includes an outer rod 131, the inner cavity of the outer rod 131 is movably connected to the inner rod 132, the outer surface of the inner rod 132 is movably sleeved with a second tension spring 133, a side of the middle of the inner cavity of the movable frame 2 is hinged with an inclined plate 15, the middle of the inner cavity of the movable frame 2 close to the T-shaped block 11 is fixedly connected to an L-shaped spring sheet 14, the front and rear ends of the bottom of one side of the inner cavity of the movable frame 2 are fixedly connected to a magnetic charging head 16, and the front and rear ends of the bottom of the scanning translation pen body 7 close to the magnetic charging head 16 are provided with a charging port 17; by pressing the T-shaped block 11 downward, the bottom of the T-shaped block 11 will squeeze the card block 9 to be located at the inclined surface in the inner cavity of the protective shell 1, so that the card block 9 is located at one end of the inner cavity of the movable frame 2 The movable frame 2 moves to the side away from the movable frame 2, thereby releasing the clamping block 9 from the movable frame 2. At this time, due to the tension of the second tension spring 133, the inner rod 132 moves upward, thereby driving the movable frame 2 and the scanning translation pen body 7 to move upward and then disengage from the inner cavity of the movable frame 2. Then the operator presses the inclined plate 15 toward the side close to the scanning translation pen body 7, which will cause the top of the inclined plate 15 to rotate counterclockwise with the hinge between the bottom of the inclined plate 15 and the movable frame 2 as the axis, so that the top of the inclined plate 15 squeezes one side of the scanning translation pen body 7, thereby causing the scanning translation pen body 7 to detach from the interior of the movable frame 2, thereby making it convenient for the operator to take out the scanning translation pen body 7.

[0028] like Figure 3 , Figure 5 , Figure 6 As shown, the bottom of the scanning translation pen body 7 is engaged with the inner cavity at the top of the protective cover 4, the bottom of the pressure plate 6 is arc-shaped on the side away from the T-block 11, and the bottom of the pressure plate 6 is in contact with the top of the scanning translation pen body 7. The soft pad 8 is located at the front and rear ends of the scanning translation pen body 7 close to the T-block 11, and the soft pad 8 is in contact with the scanning translation pen body 7. The soft pad 8 is made of rubber material; the arc-shaped part of the bottom of the pressure plate 6 is squeezed by the top of the scanning translation pen body 7, so that the first tension spring 5 is compressed. When the top of the charging port 17 is completely in contact with the bottom of the magnetic charging head 16, the scanning translation pen body 7 is fixed.

[0029] like Figure 3 , Figure 5 , Figure 6As shown in the figure, the clamping block 9 is located in the middle of one side of the movable frame 2 in the inner cavity of the protective shell 1. The outer surface of the clamping block 9 close to the movable frame 2 is fitted and clamped with the inner cavity of the movable frame 2. The middle part of the upper surface of the clamping block 9 on one side in the inner cavity of the movable frame 2 is bevel-shaped, and one side of the clamping block 9 in the inner cavity of the protective shell 1 is bevel-shaped. The bottom of the T-shaped block 11 is bevel-shaped, and the bottom of the T-shaped block 11 is fitted and pressed against the bevel surface at the top of the clamping block 9 in the inner cavity of the protective shell 1. The bottom of the second spring piece 12 is fixedly connected to the inner cavity of the protective shell 1, and the side of the first spring piece 10 away from the clamping block 9 is fixedly connected to the inner cavity of the protective shell 1; through the clamping connection between the clamping block 9 and the movable frame 2, the movable frame 2 is fixed, thereby preventing the movable frame 2 from rising due to the elastic force of the telescopic rod structure 13. At the same time, when the operator presses down the T-shaped block 11, the bevel surface of the clamping block 9 inside the protective shell 1 will be squeezed, so that the clamping block 9 moves to the side away from the movable frame 2, and at the same time, the clamping connection of the clamping block 9 to the movable frame 2 is released. At this time, due to the elastic force of the telescopic rod structure 13, the movable frame 2 will drive the scanning translation pen body 7 to disengage from the inside of the protective shell 1, so as to facilitate the operator to take out the scanning translation pen body 7.

[0030] As Figure 5 , Figure 6 shown, the top of the inner rod 132 is fixedly connected to the lower surface of the upper parts of the front and rear ends of the movable frame 2. The upper and lower ends of the second tension spring 133 are respectively fixedly connected to the top of the inner cavity of the outer rod 131 and the upper surface of the lower end of the inner rod 132. The top of the L-shaped spring piece 14 close to the inclined plate 15 is fixedly connected to the inclined plate 15. The inner cavity at the bottom of the inclined plate 15 is hinged to the movable frame 2. The L-shaped spring piece 14 is movably connected to the inner cavity of the protective shell 1. The magnetic charging head 16 and the charging port 17 are magnetically connected; through the design of the L-shaped spring piece 14, when the operator presses the inclined plate 15 to take out the scanning translation pen body 7, at this time, due to the elastic force of the L-shaped spring piece 14, the inclined plate 15 will be reset, so as to facilitate the operator's next use. At the same time, through the design of the magnetic connection between the magnetic charging head 16 and the charging port 17, when the operator puts the scanning translation pen body 7 into the inside of the movable frame 2 for storage, the magnetic charging head 16 and the charging port 17 are in contact, thereby playing a role in charging the scanning translation pen body 7 and facilitating the operator's use.

[0031] The working principle and usage process of the present invention:

[0032] For the first time, the operator inserts the bottom of the scanning translation pen body 7 into the inner cavity of the protective cover 4, and at the same time, the top of the scanning translation pen body 7 is pressed and contacted with the bottom of the pressing plate 6. Then, the operator presses the movable frame 2 downward, so that the movable frame 2 drives the scanning translation pen body 7 to move downward. At this time, the telescopic rod structure 13 is in a compressed state, and at the same time, the bottom of the movable frame 2 will squeeze the inclined surface of the card block 9 close to the side of the movable frame 2, so that the card block 9 moves to the side away from the movable frame 2. When the card block 9 is completely located in the inner cavity of the protective shell 1, the movable frame 2 continues to move downward. When the inner cavity of the middle part of the movable frame 2 close to the card block 9 is at the same height as the outer surface of the card block 9, at this time, due to the elastic force of the first spring sheet 10, the card block 9 will be inserted into the middle part of the inner cavity of the movable frame 2 close to the card block 9, thereby fixing the movable frame 2. At this time, the scanning translation pen body 7 will be inside the protective shell 1, thereby protecting and storing the scanning translation pen body 7, thereby facilitating the use of the operator;

[0033] When the operator needs to take out the scanning translation pen body 7 for use, the operator presses the T-shaped block 11 downward, which will cause the bottom of the T-shaped block 11 to squeeze the card block 9 at the inclined surface in the inner cavity of the protective shell 1, thereby causing the end of the card block 9 located in the inner cavity of the movable frame 2 to move toward the side away from the movable frame 2, thereby causing the card block 9 to release the clamping connection with the movable frame 2. At this time, due to the tension of the second tension spring 133, the inner rod 132 will move upward, thereby driving the movable frame 2 and the scanning translation pen body 7 to move upward and then disengage from the inner cavity of the movable frame 2. Subsequently, the operator presses the inclined plate 15 toward the side close to the scanning translation pen body 7, which will cause the top of the inclined plate 15 to rotate counterclockwise with the hinge between the bottom of the inclined plate 15 and the movable frame 2 as the axis, thereby causing the top of the inclined plate 15 to squeeze one side of the scanning translation pen body 7, thereby causing the scanning translation pen body 7 to disengage from the inside of the movable frame 2, thereby facilitating the operator to take out the scanning translation pen body 7 and facilitating the use of the operator.
