Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically a fabric pH value measuring instrument. Background Technology

[0002] Fabric refers to a sheet-like material made from various yarns through weaving, knitting, non-woven or other methods. It is the basic material for making clothing, shoes, hats, bags, home furnishings, industrial products, etc. Fabrics have a variety of properties, and different fabrics are suitable for different uses. There are many types of fabrics, and different compositions and processes make the performance and uses of fabrics different. When choosing a fabric, it is necessary to decide based on the end use of the product and the required functions. Fabrics are not only widely used in daily life, but also play an important role in high-tech fields such as medical, military, and aerospace.

[0003] A search revealed a utility model patent with publication number CN208206921U, which discloses an H-value measuring instrument belonging to the field of pH value detection technology. The instrument includes a detection box, a detection rod, and a cleaning device. A signal line connects the detection box and the detection rod. The detection rod is mounted on the cleaning device. The detection box has a display screen and an adjustment plate. An alarm is located on one side of the display screen, and a power switch is located on one side of the adjustment plate. A winding box is also located on one side of the detection box. The detection rod includes a connecting rod and a measuring probe. The cleaning device includes a cleaning tank, an infusion pump, and a water storage tank. The cleaning tank has several water inlets at its upper end, each with a nozzle. An outlet is located at the bottom of the cleaning tank and connected to a water outlet pipe. An inlet pipe connects the water inlets to the infusion pump, and a water storage tank is connected to the inlet of the infusion pump. This utility model has a simple structure, is easy to operate, provides good cleaning results, and has a long probe lifespan.

[0004] However, the above design still has shortcomings. In the above design, the cleaning effect is good and the probe has a long service life, but during the testing process, the testing instrument may be dropped due to careless operation or slipping, causing damage to the instrument. In addition, it cannot be flexibly adjusted, making it unable to adapt to various working environments and staff with different habits. Therefore, we propose a fabric pH value meter to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a fabric pH value tester, including a protective shell 1. An adjustment disc 5 is connected to the right side of the protective shell 1. A bidirectional screw 18 is rotatably connected to the inner wall of the protective shell 1. The output end of the adjustment disc 5 passes through the outer wall of the protective shell 1 and is fixedly connected to one end of the bidirectional screw 18. The cooperation between the adjustment disc 5 and the bidirectional screw 18 ensures that the instrument can move up and down. Two sliders 19 are threadedly connected to the outer surface of the bidirectional screw 18. A U-shaped block 17 is connected to the upper surface of each slider 19. A connecting rod 21 is rotatably connected to the inner wall of each U-shaped block 17. The two connecting rods 21 are hinged on their sides that are close to each other. A support plate 20 is slidably connected to the ends of the two connecting rods 21 that are away from the U-shaped block 17. The user can adjust the height of the support plate 20 by simple rotation and sliding operations. A set of damping rods 2 are slidably connected to the bottom surface of the protective shell 1. A buffer spring 4 is sleeved on the outer surface of each damping rod 2. During operation, if the instrument is accidentally dropped or impacted, the buffer spring 4 can play a certain protective role and reduce damage.

[0023] The upper surface of the support plate 20 is connected to the main body 14 of the device. The support plate 20 serves as the support surface for the main body 13 of the device, which can ensure the stability of the entire instrument and reduce the movement of the instrument due to external vibration or improper operation. Each damping rod 2 is connected to a support foot 3 at its bottom end.

[0024] The device body 14 has a display screen 12 attached to its upper surface. The display screen 12 can intuitively display measurement data, operation menus, status indicators and other information, making it convenient for users to read and interpret measurement results. A set of control keys 13 is installed on the upper surface of the device body 14. The installation position of the control keys 13 is convenient for users to operate, and they can quickly input commands, adjust settings or navigate menus, which improves the operability of the instrument.

[0025] The device body 14 has a maintenance door 10 hinged to its upper surface. The hinged maintenance door 10 can be opened quickly, reducing preparation work during maintenance and improving maintenance efficiency. The upper surface of the maintenance door 10 is connected to a pull ring 11, which can serve as a visual cue to remind the user that this is the maintenance entrance, thus avoiding damage to the instrument without their knowledge.

[0026] The inner wall of the main body 14 of the device is connected to multiple processors 15. Different processors 15 can be responsible for different functions, such as data acquisition, signal processing, and result display, enabling the instrument to perform more complex operations. The inner wall of the main body 14 of the device is connected to a built-in power supply 16, which eliminates the dependence on external power supply, allowing the instrument to be used in environments without power outlets, thus increasing portability.

[0027] The protective shell 1 has a fixing plate 9 connected to its left side. The fixing plate 9 can enhance the stability of the placement rack 8 and ensure that the placement rack 8 will not shake or fall off during operation. The placement rack 8 is connected to the upper surface of the fixing plate 9.

[0028] The device body 14 has a connecting line 6 on its left side. The end of the connecting line 6 away from the device body 14 is connected to an electrode rod 7. The electrode rod 7 is connected to the device body 14 through the connecting line 6, which allows the electrode to be safely introduced into the fabric sample for pH measurement without direct contact with the instrument's internal circuitry.

[0029] Working principle: During use, the operator first removes the electrode rod 7 from the placement rack 8, then places the electrode rod 7 in the solution to test the sample. The processor 15 processes the data, and the display screen 12 and control keys 13 are used to observe and adjust the data. When the equipment is damaged, the maintenance door 10 is opened by pulling the ring 11 to perform internal maintenance, avoiding the need to disassemble the device. The adjustment plate 5 and the bidirectional screw 18 work together to move the slider 19 closer and further away, and the U-shaped block 17 and the connecting rod 21 work together to support or maintain the support plate 20 according to the work requirements. Since the height of the main body 14 can be adjusted, under normal use, the entire device is inside the protective shell 1, thus preventing the instrument from falling and being damaged due to careless operation or slipping during the testing process. At the same time, after a fall, the damping rod 2 and the buffer spring 4 at the bottom work together to cushion the impact and prevent damage to the internal electrical components of the instrument.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
