Description

Technical Field

[0001] This utility model relates to the field of test point marking technology, and in particular to an auxiliary device for marking circuit test points. Background Technology

[0002] In the process of circuit testing and maintenance, it is crucial to clearly and accurately mark the test points. Label printers are needed to assist in the marking process. Label printers can print out the marking labels and attach them to the appropriate areas so that engineers can quickly locate the test points, thereby effectively reducing the occurrence of mistests and missed tests.

[0003] Existing label printers have operation buttons on the top of the machine to control power supply and parameter adjustment. The paper output tray is usually located on the top or front of the machine. When the operator peels off the label, they need to pull it outward from the paper output tray. If the button is too close to the paper output tray and is exposed, the operator may accidentally touch it, which could lead to unexpected changes in printing parameters, affecting label printing quality and efficiency. To address this issue, we propose a circuit test point marking auxiliary device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for marking circuit test points.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circuit test point marking auxiliary device includes a printer body, an operation button on the upper side of the printer body, a paper output port on the upper side of the printer body, a connecting plate on the upper side of the printer body, and a connecting block fixedly connected to the upper side of the connecting plate. A connecting shaft is movably inserted inside the connecting block, and both ends of the connecting shaft are fixedly connected to a fixed plate. The side of the fixed plate is connected to a cover frame. A torsion spring is connected to one side of the fixed plate that is close to the other side, and the other end of the torsion spring is connected to the side of the connecting block.

[0007] Preferably, a pull block is fixedly connected to the front side of the cover frame, and the pull block is configured as a long strip structure.

[0008] Preferably, the side of the cover frame is glued with a rubber sheet, and the rubber sheet is configured with a U-shaped structure.

[0009] Preferably, protective pads are glued to the corners of the cover frame, and the protective pads are configured in an L-shape.

[0010] Preferably, the connecting plate has symmetrical slots inside, and each slot has a threaded rod inserted inside. The top of the threaded rod is fixedly connected to a limiting cap, and the printer body has screw holes inside that are compatible with the threaded rods.

[0011] Preferably, there are two sets of connecting blocks and fixing plates, and the two sets of connecting blocks and fixing plates are symmetrically distributed about the central axis of the cover frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device is equipped with a connecting block and a cover frame. During use, the connecting block and the cover frame work together to cover the operation buttons, which can effectively prevent the operator from accidentally touching the operation buttons during the printing process. This can effectively ensure the continuity of the printing process and improve the printing efficiency of this device.

[0014] 2. This device is equipped with a pull block and a rubber plate. During use, the rubber plate effectively prevents the cover frame from directly colliding with the outer wall of the printer body when it is reset, thus protecting both of them. With the pull block, it is easy for the operator to quickly pull the cover frame to rotate and press the corresponding operation button. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A circuit test point marking auxiliary device includes a printer body 1, an operation button 2 on the upper side of the printer body 1, and a paper output port 14 on the upper side of the printer body 1. The specific printing principle of the printer body 1 is existing technology and will not be described in detail here. A connecting plate 3 is provided on the upper side of the printer body 1, and a connecting block 4 is fixedly connected to the upper side of the connecting plate 3. A connecting shaft 5 is movably inserted inside the connecting block 4, and both ends of the connecting shaft 5 are fixedly connected to a fixing plate 6. The side of the fixing plate 6 is connected to a cover frame 8, and a torsion spring 7 is connected to the side of the fixing plate 6 that is close to each other. The other end of the torsion spring 7 is connected to the side of the connecting block 4. Since the connecting shaft 5 is movably inserted inside the connecting block 4, the rotation requirements of the connecting shaft 5 can be met, making it easy for the operator to pull the cover frame 8 to flip. With the connection of the torsion spring 7, the cover frame 8 can be effectively ensured to tightly cover the upper side of the operation button 2. In addition, the cover frame 8 can be made of acrylic material, so that the operator can easily see the position of the operation button 2 and the data on the display screen. The cover frame 8 can also protect the display screen, thereby effectively extending the service life of the device.

[0022] Furthermore, refer to Figure 2 It can be seen that a pull block 9 is fixedly connected to the front side of the cover frame 8, and the pull block 9 is set as a long strip structure. Through the pull block 9 set as a long strip structure, it is easy for the staff to apply an upward pulling force to the cover frame 8, so that the cover frame 8 can be flipped quickly.

[0023] Furthermore, refer to Figure 3 It can be seen that the side of the cover frame 8 is glued with a rubber plate 10, and the rubber plate 10 is set with a U-shaped structure. The rubber plate 10 with the U-shaped structure can make the cover frame 8 flexibly abut against the outer wall of the printer body 1 when it is reset, so as to buffer the impact force when it is reset, thereby realizing the protection operation of the printer body 1 and the rubber plate 10.

[0024] Furthermore, refer to Figure 2 It can be seen that protective pads 11 are glued to the corners of the cover frame 8, and the protective pads 11 are set in an L-shaped structure. During use, the rubber protective pads 11 set in an L-shaped structure can protect the corners of the cover frame 8, thereby preventing the corners of the cover frame 8 from being easily damaged.

[0025] Furthermore, refer to Figure 3 and Figure 4It can be seen that the connecting plate 3 has symmetrical slots inside, and threaded rods 12 are inserted into the slots. The top of the threaded rod 12 is fixedly connected to the limit cap 13. The printer body 1 has screw holes that are compatible with the threaded rods 12. The connecting plate 3 can be disassembled by the cooperation of the threaded rods 12 and the screw holes. After long-term use of this device, the operator can use a tool to rotate the limit cap 13 to drive the threaded rods 12 to rotate, so that the threaded rods 12 can be removed from the printer body 1 to disassemble the connecting plate 3. Therefore, it is convenient for the operator to replace the damaged cover frame 8.

[0026] Furthermore, refer to Figure 1 It can be seen that there are two sets of connecting blocks 4 and fixing plates 6, and the two sets of connecting blocks 4 and fixing plates 6 are symmetrically distributed about the central axis of the cover frame 8. Since there are two sets of connecting blocks 4 and fixing plates 6, there are also two sets of connecting shaft 5 and torsion spring 7. By setting two sets of connecting blocks 4 and fixing plates 6, the stable rotation of the cover frame 8 can be effectively guaranteed.

[0027] Working Principle: When using this utility model, the operator can first place the sticky note roll into the printer body 1, and then pull the pull block 9 to drive the cover frame 8 to rotate under force. At this time, the fixed plate 6 connected to the cover frame 8 is driven by force to drive the connecting shaft 5 to rotate. At this time, the cover frame 8 is in a flipped state. Therefore, the operator can press the operation button 2 set on the upper side of the printer body 1 to control the power supply and parameter adjustment. After pressing, the operator can stop pulling the pull block 9, so that the cover frame 8 is reset by the elastic force of the torsion spring 7, which can drive the cover frame 8 to cover the operation button 2 again. Then the printed sticky note paper can be discharged from the paper outlet 14. The operator can then tear off the sticky note paper and attach it to the position of the circuit test point to realize the marking operation of the test point. The above is the complete working principle of this utility model.

[0028] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
