Description

Technical Field

[0001] The utility model belongs to the field of anti-pinch testing, and in particular relates to an anti-pinch force measuring tool for sliding doors. Background Art

[0002] The platform door system is one of the main systems that directly protect and transport passengers. The status of the system and equipment is directly related to the safety of passengers. As subway operating units gradually pay more attention to ensuring passenger safety, the technical standards and maintenance requirements of platform door equipment also need to be gradually strengthened. Because the manufacturers and types of platform door equipment used in various subway lines are different, the existing technical specifications cannot meet the equipment maintenance needs.

[0003] In particular, each sliding door needs to undergo an anti-pinch function test every month. The anti-pinch test piece uses a 5mm thick and 40mm wide steel plate. The last 100mm stroke of a single sliding door, the lower part (400mm), middle part (1000mm) and upper part (1600mm) of the height direction between two sliding doors are tested. After the sliding door contacts the steel plate, it should be detected. The door controller controls the sliding door to automatically enter the obstacle detection mode, and the measured closing force threshold does not exceed 150N. At present, the test requires manual measurement of the height with a steel ruler and marking, and then measuring the last 100mm of the closing stroke. Finally, the left and right door bodies are manually hooked for testing. There is no special anti-pinch function test device and the human interference factor is large. Repeated measurements are required to take the average value. Therefore, it is necessary to study special devices. When the door is closed at a test distance of 100mm, the tension test device is changed to an extrusion force test device to improve work efficiency and test accuracy.

[0004] Based on this, the utility model proposes a sliding door anti-pinch force measuring tool. Utility Model Content

[0005] In order to solve the above problems in the prior art, that is, there is no dedicated anti-pinch function experimental device in the prior art and the human interference factor is relatively large, the utility model provides a sliding door anti-pinch force measuring tool, including a force measuring sensor, a spring, and a long ruler;

[0006] The force sensor is installed on one side of the ruler close to the sliding door, and the force sensor is fixed to one end of the spring on both sides close to the sliding door, and the other end of the spring can be squeezed by the sliding door;

[0007] The ruler is provided with a length adjustment mechanism, and the length adjustment mechanism is used to adjust the length of the ruler. By adjusting the length of the ruler, the ruler can be detachably fixed on the pillars on both sides of the sliding door.

[0008] In some preferred embodiments, the springs fixed to the force sensor on both sides close to the sliding door are not on the same horizontal plane.

[0009] In some preferred embodiments, a display controller is installed on the ruler, and the display controller is electrically connected to the force sensor. The display controller is used to adjust and calibrate the parameters of the force sensor and display pressure data.

[0010] In some preferred embodiments, a handle is installed on the ruler.

[0011] In some preferred embodiments, anti-skid pads are installed at both ends of the ruler, and the anti-skid pads are used to contact the pillars on both sides of the sliding door.

[0012] In some preferred embodiments, the force sensor is installed at the midpoint of a side of the ruler close to the sliding door.

[0013] In some preferred embodiments, the ruler is an aluminum alloy ruler.

[0016] The other end of the spring is fixed to a pressing plate, and the pressing plate can be pressed by the sliding door.

[0017] Beneficial effects of the utility model:

[0018] (1) Improve detection efficiency and automation: By fixing the force sensor on an adjustable ruler and using springs as a buffer and force transmission medium, the device realizes the fully automated operation of the sliding door clamping force test. No manual handheld sensor is required, which reduces manpower input, improves the speed and efficiency of detection, and makes large-scale routine safety inspections more convenient.

[0019] (2) Enhanced data accuracy and consistency: Since the springs on both sides of the force sensor are not designed to be on the same horizontal plane, the interference caused by the interaction between the two springs is effectively avoided, ensuring that the measured clamping force data is purer and more accurate, reducing errors in the test process, and improving the consistency and comparability of the test results.

[0020] (3) Improved safety: The device can complete the test without direct human intervention, significantly reducing the risk of injury during the test. In particular, it ensures the safety of testers in scenarios that may involve squeezing risks, such as evaluating the closing force of sliding doors.

[0021] (4) Flexibility and wide applicability: The adjustable length of the ruler enables the device to adapt to sliding door structures of different sizes and types. Whether it is a small sliding door for home use or an automatic door system in a large public facility, precise adaptation can be achieved by adjusting the length of the ruler, thereby enhancing the versatility and practicality of the device.

[0025] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figure 1-Figure 2 As shown, see Figure 1 , the first embodiment of the utility model provides a sliding door anti-pinch force measuring tool, including a force measuring sensor 1, a spring 2, and a long ruler 3;

[0028] The force sensor 1 is installed on one side of the long ruler 3 close to the sliding door, and the force sensor 1 is fixed to one end of the spring 2 on both sides close to the sliding door, and the other end of the spring 2 can be squeezed by the sliding door;

[0029] The ruler 3 is provided with a length adjustment mechanism, and the length adjustment mechanism is used to adjust the length of the ruler 3. By adjusting the length of the ruler 3, the ruler 3 can be detachably fixed to the pillars on both sides of the sliding door.

[0030] Among them, see Figure 2 In this embodiment, the length adjustment mechanism may be, but is not limited to, a squeezing spring 33. The squeezing spring 33 is used to adjust the length of the ruler 3, specifically:

[0031] The long ruler includes a first long ruler 31 and a second long ruler 32;

[0032] The first ruler 31 and the second ruler 32 are both hollow structures. The second ruler 32 is disposed inside one end of the first ruler 31 and moves along the first ruler 31. One end of a compression spring 33 is fixed inside the first ruler 31. The other end of the compression spring 33 is fixed to the outer surface of the second ruler 32. The compression spring 33 always has a force that causes the first ruler 31 and the second ruler 32 to move in opposite directions.

[0033] The second long ruler 32 and the pressing spring 33 are symmetrically arranged in two groups along the midpoint of the first long ruler 31 .

[0034] When using the above embodiment, the second ruler 32 on both sides is manually squeezed to move the second ruler 32 into the first ruler 31 until the second ruler 32 on both sides overlaps the column and the column is always squeezed outward, thereby fixing the entire tool on the column.

[0035] One end of the squeezing spring 33 is fixed inside the first ruler 31 . Specifically, a partition is fixed inside the first ruler 31 , and the partition is fixed to one end of the squeezing spring 33 .

[0036] In this embodiment, as a further explanation of the present invention, anti-skid pads 6 are installed at both ends of the long ruler 3, and the anti-skid pads 6 are used to contact with the pillars on both sides of the sliding door.

[0037] Specifically, the anti-slip pads 6 are installed on both sides of the second ruler 32 .

[0038] The utility model can fix the long ruler 3 on the column more stably through the above content, so that the measurement result is more accurate and the long ruler 3 can be prevented from falling during the test.

[0039] For further explanation of the present invention, see Figure 1 and Figure 2 The force sensor 1 is installed at the midpoint of the side of the long ruler 3 close to the sliding door.

[0040] Since sliding doors are generally arranged and moved symmetrically, the force sensor 1 of the present invention is installed at the midpoint of the long ruler 3, so that the sliding door can simultaneously exert force on the springs 2 on both sides.

[0041] Specifically, the force sensor 1 is installed at the midpoint of the first ruler 31 .

[0042] The force sensor 1 of the present invention can sense pressure changes on both sides, and thus can detect the anti-pinch force of the anti-slip door on both sides at the same time.

[0043] For further explanation of the present invention, see Figure 1 and Figure 2 , the springs 2 fixed on both sides of the force sensor 1 close to the sliding door are not on the same horizontal plane.

[0044] Among them, the utility model can avoid inaccurate data caused by artificial force or interaction force between the springs 2 when the anti-slip doors on both sides squeeze the springs 2 on both sides at the same time through the above content.

[0045] For further explanation of the present invention, see Figure 1 and Figure 2 A display controller 4 is installed on the ruler 3. The display controller 4 is electrically connected to the force sensor 1. The display controller 4 is used to adjust and calibrate the parameters of the force sensor 1 and display pressure data.

[0046] The display controller 4 is embedded in the first ruler 31 and is detachably fixed to the first ruler 31 .

[0047] The present invention can facilitate the replacement of the display controller 4 through the above content.

[0048] For further explanation of the present invention, see Figure 1 and Figure 2 , a handle 5 is installed on the first ruler 31.

[0049] The utility model can facilitate the operation of the user by providing the handle 5 , and the user can hold the handle 5 to install the ruler 3 on the pillars on both sides.

[0050] For further explanation of the present invention, see Figure 1 and Figure 2 The first ruler 31 and the second ruler 32 are both aluminum alloy rulers.

[0051] For further explanation of the present invention, see Figure 1 and Figure 2 , the force sensor 1 is a pressure sensor.

[0052] For further explanation of the present invention, see Figure 1 and Figure 2 , the other end of the spring 2 can be squeezed by the sliding door, and its specific structure is:

[0053] The other end of the spring 2 is fixed to a pressing plate 7, and the pressing plate 7 can be pressed by the sliding door.

[0054] When the utility model is in use, the display controller 4 is first opened to perform calibration and adjustment. After measuring the correct height value, the handle 5 is held to adjust the length of the ruler 3, and the ruler 3 is placed against the pillars on both sides of the sliding door. When waiting for the sliding door to be closed, the anti-collision rubber strips on the left and right door bodies squeeze the middle spring 2 to form a uniform deceleration until the door body stops closing, triggering the anti-pinch spring to open. The dynamometer sensor 1 measures the pressure data and uploads it to the display screen of the display controller 4. The data is the anti-pinch force when the left and right doors of the sliding door are closed.
