Description

Technical Field

[0001] This utility model relates to the field of terminal identification sign technology, specifically to a railway signal wiring terminal identification sign device. Background Technology

[0002] In fields such as railway signaling systems and industrial automation control, the labeling of wiring terminals is crucial for ensuring efficient equipment maintenance and repair. Traditional labeling methods, such as adhesive paper labels or fixed metal nameplates, have several shortcomings: Firstly, adhesive paper labels are susceptible to environmental factors, and in humid, oily, or frequently touched environments, they are prone to falling off, fading, or being damaged, resulting in unclear labeling information and increasing the risk of misoperation. Secondly, once fixed metal nameplates or ordinary plastic labels are installed, their labeling content is difficult to adjust. When the equipment wiring layout changes or the terminal purpose is updated, the entire label needs to be replaced, which is cumbersome and costly.

[0003] Furthermore, existing signage devices lack convenience in their structural design. Some signs cover the terminal surfaces, requiring the removal and reinstallation of the signs before wiring, which not only affects work efficiency but may also lead to lost or damaged signs. Therefore, there is an urgent need for a signage device that is durable, has adjustable signage content, is easy to operate, and adaptable to various usage scenarios to solve the problems existing in the current technology.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] This utility model provides the following technical solution: a railway signal wiring terminal identification device. During use, this utility model achieves flexible adjustment of the identification content by setting a rotatable font wheel and a drive component. Operators only need to turn a knob to rotate the font wheel through the cooperation of the drive wheel and the locking wheel, adjusting the numbers, letters, or symbols displayed on the font wheel. There is no need to replace the entire identification device, adapting to scenarios of equipment wiring changes or terminal usage updates, reducing usage costs and improving work efficiency.

[0023] The labels are made of synthetic paper and feature a storage tube and rewind lever design, ensuring both durability and convenient storage. The synthetic paper's weather resistance and damage resistance allow it to withstand harsh environments such as humidity, oil, and frequent contact. The rewind lever and return torsion spring work together to automatically rewind the labels into the storage tube when not in use, preventing damage from external forces and further extending the label's lifespan. Figures 1-4 The diagram shown is a structural schematic of the first embodiment of the railway signal wiring terminal identification plate device of this utility model. Please refer to [link / reference]. Figures 1-4 The railway signal wiring terminal identification sign device of this embodiment includes a housing 100 as its main body. The housing 100 is made of ABS engineering plastic, which has good impact resistance and corrosion resistance, and can adapt to the industrial environment. Two wire clips 110 are integrally formed on the top of the housing 100. The inner side of the wire clips 110 is provided with anti-slip rubber pads. The device can be fixed to a cable or terminal block bracket with a diameter of 5-15mm through the wire clips 110. The installation is convenient and the device is firmly fixed, preventing the device from shaking or falling off during use.

[0024] A transparent acrylic display window 120 is embedded in the front of the housing 100. The size of the display window 120 is adapted to the distribution range of the font wheels 130, ensuring that the staff can clearly see the markings on the font wheels 130. The transparent acrylic has high light transmittance and scratch resistance, and is not easily blurred after long-term use. Inside the housing 100, four font wheels 130 are rotatably connected via a pivot. The four font wheels 130 are evenly distributed in a straight line inside the housing 100. The outer circumference of each font wheel 130 is engraved with numbers 0-9, letters AZ, or common symbols (such as "+", "-", "GND", etc.). By rotating different font wheels 130, terminal numbers (such as "X1-01"), uses (such as "power input"), destinations (such as "distribution panel #1 terminal"), and other markings can be formed to meet diverse marking needs.

[0025] Each font wheel 130 has a fixedly connected snap-fit ​​wheel 140 in its inner cavity. The snap-fit ​​wheel 140 is coaxially arranged with the font wheel 130. The inner cavity of the snap-fit ​​wheel 140 has 10 evenly spaced grooves (the number of grooves matches the number of characters on the font wheel 130). The grooves are arc-shaped to facilitate engagement with the snap-fit ​​blocks on the drive wheel 152. The housing 100 also has a drive assembly 150, which includes a shaft 151. The shaft 151 is made of stainless steel, which has good strength and wear resistance. The shaft 151 is rotatably connected to the housing 100 through bearings to ensure smooth rotation. One end of the shaft 151 is welded and fixed to a drive wheel 152. Four locking blocks are evenly arranged on the drive wheel 152 (the four locking blocks are staggered with the ten grooves of the locking wheel 140, and can engage different grooves one by one during rotation to achieve precise gear adjustment of the font wheel 130). The shape of the locking blocks matches the grooves in the inner cavity of the locking wheel 140, and the locking blocks are made of elastic plastic material, which has a certain deformation capacity during the locking process to avoid jamming. The other end of the shaft 151 passes through the housing 100 and is fixedly connected to the knob 153 by screws. The outer surface of the knob 153 is provided with anti-slip texture. When the operator rotates the knob 153, the shaft 151 drives the drive wheel 152 to rotate. The locking blocks on the drive wheel 152 engage with the grooves of the locking wheel 140, thereby driving the font wheel 130 to rotate synchronously to achieve adjustment of the marking content. After adjustment, the locking structure of the locking blocks and grooves can position the font wheel 130 to prevent it from rotating on its own.

[0026] A connecting block 160 is fixedly connected to the bottom of the housing 100 by screws. A storage tube 200 is integrally formed at the bottom of the connecting block 160. The storage tube 200 is made of transparent PVC material, which makes it easy for staff to observe the remaining amount of internal label paper 240. A support platform 210 is welded and fixed inside the storage tube 200. The support platform 210 has a U-shaped structure. The inner cavity of the support platform 210 is rotatably connected to a winding rod 220 through a bearing. A return torsion spring 230 is fitted at the connection between the winding rod 220 and the support platform 210. One end of the return torsion spring 230 is welded and fixed to the support platform 210, and the other end is welded and fixed to the winding rod 220. The winding rod 220 is wound with a labeling paper 240, which is a synthetic paper made of polypropylene, polyethylene and plastic resin materials through extrusion and stretching to form a film and then undergoing paper-like treatment. The synthetic paper is 0.1mm thick, has a tear strength of ≥20N, and a water resistance rating of IPX7. It can be used normally in environments ranging from -40℃ to 120℃, and its surface can be marked with detailed terminal parameter information (such as voltage, current, wiring specifications, etc.) by printing. The bottom of the label paper 240 is glued with a pull-out block 250, which is made of rubber for easy gripping by staff. The bottom of the storage tube 200 has a groove, the width of which is 0.5mm wider than the width of the label paper 240. The label paper 240 extends through the groove to the outside of the storage tube 200. When it is necessary to view the detailed information on the label paper 240, the staff only needs to pull the pull-out block 250 to pull the label paper 240 out of the storage tube 200. After viewing, the pull-out block 250 is released, and the reset torsion spring 230 drives the winding rod 220 to rotate in the opposite direction under the action of the reset spring force, automatically winding the label paper 240 back into the storage tube 200, preventing the label paper 240 from being damaged due to long-term exposure.

[0027] Combination Figures 1-4 The railway signal wiring terminal identification device of this embodiment works on the following principle: When using this adjustable identification device, firstly, the device is fixed to the cable or terminal block bracket by the wire clamp 110 on the top of the housing 100, ensuring that the display window 120 faces a direction that is easy to observe. According to the actual information of the terminal, rotate the knob 153 on the outside of the housing 100. The knob 153 drives the drive wheel 152 to rotate through the shaft 151. The locking block on the drive wheel 152 cooperates with the groove of the locking wheel 140, driving the font wheel 130 to rotate. Adjust the characters on the four font wheels 130 so that they combine to form the core identification content such as the terminal number and purpose. After the adjustment is completed, the locking structure of the locking block and the groove positions the font wheel 130 to prevent the characters from shifting.

[0028] When detailed parameter information of the terminal is needed, the staff grabs the pull block 250 at the bottom of the storage tube 200 and pulls the label paper 240 out of the groove of the storage tube 200. The label paper 240 drives the winding rod 220 to rotate, and the reset torsion spring 230 between the winding rod 220 and the support platform 210 deforms and stores the elastic force. After viewing the detailed information, the pull block 250 is released, the reset torsion spring 230 releases the elastic force, drives the winding rod 220 to rotate in the opposite direction, and rewinds the label paper 240 back into the storage tube 200 to complete the storage.

[0029] When the equipment is being maintained or the wiring is being changed, if the label content needs to be adjusted, simply turn the knob 153 again and repeat the above adjustment steps for the font wheel 130. There is no need to replace the entire label device, making the operation convenient and cost-effective. At the same time, the synthetic paper label paper 240 and the ABS plastic shell 100 have good durability and can be used stably in harsh environments for a long time, effectively ensuring the clarity and integrity of the label information.
