Description

Technical Field

[0001] This utility model relates to the field of measuring tools, and in particular to a measuring tool for train seat cushions. Background Technology

[0002] With the rapid development of the railway transportation industry, high-speed trains have become one of the important means of transportation for people's daily travel. To ensure passenger comfort, the maintenance and repair of high-speed train seats is crucial. Among these factors, the degree of seat cushion sagging is a key factor affecting passenger comfort. When the seat cushion sagging reaches a certain level, it needs to be replaced to ensure a comfortable passenger experience.

[0003] During the inspection and maintenance of high-speed trains, accurately replacing substandard seat cushions requires precise measurement of the cushion's sagging. However, seat cushion deformation is complex, including not only vertical sagging at the bottom but also cushion tilting caused by uneven sagging from side to side. Therefore, it is necessary to quantitatively measure the vertical sagging and the tilt angle caused by the difference in height between the left and right sides to accurately determine whether the seat cushion needs to be replaced.

[0004] Furthermore, the seats on high-speed trains include three categories: second-class, first-class, and business-class, with widths ranging from 350mm to 550mm, and different permissible depths of seat sagging. This significantly increases the difficulty of measurement, resulting in extremely low work efficiency. Existing measurement tools and methods cannot quickly adapt to seats of different class, making it difficult to achieve rapid and accurate measurement of seat cushion deformation, thus affecting the precise inspection and maintenance of seat cushions. Utility Model Content

[0005] The purpose of this invention is to provide a measuring tool for train seat cushions, which can quickly measure the vertical collapse and tilt angle of different types of seat cushions, thereby improving work efficiency.

[0006] In a first aspect, this utility model provides a measuring tool for the seat cushion of a high-speed train, comprising:

[0007] The mounting base is provided with a first slide rail groove and a second slide rail groove. The first slide rail groove is located on the bottom surface of the mounting base, and the second slide rail groove is located on the side surface of the mounting base. The opening direction of the first slide rail groove is perpendicular to the grooving direction of the second slide rail groove.

[0008] An adjustable base plate is movably disposed within the first slide rail groove. The adjustable base plate can be moved to be exposed or stored within the first slide rail groove to adjust the measuring dimensions of the mounting base.

[0009] A depth measuring ruler is movable within the second slide rail groove to measure the amount of cushion collapse at different locations.

[0010] This utility model provides a seat cushion measuring tool for high-speed trains. By incorporating a movable, adjustable base plate, the tool can adapt to seats of different sizes. The adjustable base plate can be moved to be exposed or retracted into a first slide rail groove, thereby adjusting the measuring dimensions of the mounting base to quickly accommodate seats of different seating classes, such as second class, first class, and business class. Furthermore, a depth measuring ruler is movable within a second slide rail groove, enabling precise measurement of the vertical sagging at different locations on the seat cushion. This movable design allows the measuring ruler to be flexibly moved to various key positions on the seat cushion, comprehensively acquiring information about the cushion's sagging, avoiding the limitations of traditional measuring tools that can only measure fixed positions, and improving the accuracy and comprehensiveness of the measurement results.

[0011] Furthermore, there are two first slide rail grooves, which are located on opposite sides of the mounting base. There are also two adjusting base plates, which are movably disposed within the two first slide rail grooves.

[0012] By adopting the above technical solution, two first slide rail grooves are respectively set on opposite sides of the mounting base, and two adjusting base plates are provided to form a symmetrical structure. This symmetrical design makes the measuring tool more stable during use, and can be evenly distributed on both sides of the seat cushion, avoiding measurement errors or tool tilting caused by uneven force on one side.

[0013] Furthermore, the length of the mounting base is 350mm, and the maximum adjustment length of both adjustment base plates is 100mm.

[0014] Using the above technical solution, the length of the mounting base is 350mm, and the maximum adjustment length of the two adjustable base plates is 100mm. The total length of the entire measuring tool can be flexibly adjusted between 350mm and 550mm, which can accurately adapt to the seat sizes of different seating classes commonly found in high-speed trains, such as second-class seats, first-class seats, and business-class seats.

[0015] Furthermore, it also includes a locking screw, and the mounting base is provided with a locking hole, the locking hole connecting the first slide rail groove and the top surface of the mounting base, the locking screw being disposed in the locking hole to lock or unlock the adjusting base plate.

[0016] The above technical solution utilizes a locking screw and locking hole design that ensures the adjusting base plate is securely fixed after being adjusted to the appropriate position. During measurement, the adjusting base plate will not move due to external forces or vibrations, thus ensuring the stability of the measuring tool and avoiding measurement errors caused by base plate movement.

[0017] Furthermore, it also includes a level for measuring the tilt angle of the seat cushion, the level being fixedly mounted above the mounting base.

[0018] By employing the above technical solution and fixing a level above the mounting base, the tilt angle of the seat cushion can be quantitatively measured. This includes not only the vertical collapse of the bottom of the cushion but also the tilt angle caused by uneven collapse from side to side. This comprehensive measurement method makes the assessment of the cushion's deformation more accurate and complete, providing a more sufficient basis for determining whether the cushion needs to be replaced.

[0019] Furthermore, the level is provided with a first display window and a second display window for displaying the tilt angle. The first display window is located on the side of the level away from the mounting base, and the second display window is located on the side of the level facing away from the second slide rail groove.

[0020] Using the above technical solution, the level has two windows, one at the front and one at the top, which can display the tilt angle simultaneously. The operator can choose the most convenient angle to take the reading according to their position and operating habits. Whether looking down at the top window or looking straight at the front window, the tilt angle value can be clearly read, improving the convenience of reading.

[0021] Furthermore, the mounting base is also equipped with a tilt alarm.

[0022] Using the above technical solution, the tilt alarm can sound an alarm when the seat cushion tilt angle exceeds a preset value, allowing operators to quickly determine whether the seat cushion deformation exceeds the specified requirements. Without the need for complex calculations or comparisons, operators can quickly draw conclusions based solely on the alarm signal, greatly improving detection efficiency.

[0023] Furthermore, the level has a first scale value on the side facing away from the depth measuring ruler; and / or, the upper surface of the adjusting base plate has a second scale value.

[0024] Furthermore, the depth measuring ruler includes a sliding block, a vertical plate, a lifting block, and a ruler body. The sliding block is movably disposed in the second slide rail groove, the vertical plate is disposed above the sliding block, the lifting block is movable on the vertical plate, the sliding block is also provided with a measuring hole, one end of the ruler body is fixedly disposed on the lifting block, and the other end passes through the measuring hole.

[0025] Using the above technical solution, the sliding block can move horizontally along the second slide rail groove, allowing the measuring ruler to be flexibly positioned at different locations on the cushion; the lifting block can move vertically up and down along the upright plate, allowing the ruler to be adjusted vertically according to the depth of the cushion's collapse. By combining the horizontal movement of the sliding block and the vertical movement of the lifting block, the operator can quickly position the measuring ruler to the required location and adjust the depth, thereby achieving accurate measurement of the amount of collapse at different locations and depths on the cushion.

[0026] Furthermore, the depth measuring ruler also includes an electronic display, which is mounted on the lifting block and is used to display the measured depth of the ruler.

[0027] Using the above technical solution, the electronic display is mounted on the lifting block, enabling real-time display of the measured depth of the ruler. This digital display method is more accurate than traditional rulers, reducing measurement inaccuracies caused by human reading errors. Operators can intuitively obtain measurement data, ensuring the reliability of the measurement results.

[0028] As can be seen from the above, the train seat cushion measuring tool provided by this utility model, through the setting of a movable adjustable base plate, can adapt to seats of different sizes. The adjustable base plate can be moved to be exposed or stored in the first slide rail groove, thereby adjusting the measuring dimensions of the mounting base, so that it can quickly adapt to seats of different seating classes such as second class, first class, and business class. In addition, the depth measuring ruler is movable in the second slide rail groove, which can accurately measure the vertical collapse of the seat cushion at different positions. This movable design allows the measuring ruler to be flexibly moved to various key positions of the seat cushion, comprehensively obtaining the collapse of the seat cushion, avoiding the limitation of traditional measuring tools that can only measure fixed positions, and improving the accuracy and comprehensiveness of the measurement results.
