[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a tooling for measuring the length of a door frame sealing strip, including a support frame 1 and a measuring device 2; the support frame 1 has a support surface 11 that matches the shape and size of the inner side of the sealing strip, for supporting the sealing strip from the inside of the sealing strip, and the support frame 1 is provided with a slide rail 12 for the measuring device 2 to slide, and the shape of the slide rail 12 matches the shape of the sealing strip; the measuring device 2 is used to slide along the slide rail 12 to measure the sealing strip, including a sliding part that slides with the slide rail 12, a mounting bracket 21 that is fixedly connected to the sliding part, and a measuring part provided on the mounting bracket 21; the measuring part includes a sensing head 22 and a laser probe 23, the sensing head 22 is used to measure the displacement of the measuring device 2, and the laser probe 23 is used to align the measuring point on the sealing strip.

[0030] In use, the inner side of the sealing strip facing the support surface 11 of the support frame 1 is fitted onto the support frame 1, so that the inner side of the sealing strip is in contact with the support surface 11 of the support frame 1. Then, the measuring device 2 can be slid along the slide rail 12 to measure the length of the sealing strip.

[0031] like Figure 1 As shown, when the sealing strip is U-shaped, the support surface 11 and the slide rail 12 on the support frame 1 are also U-shaped. The U-shaped opening of the sealing strip is placed on the support frame 1 with the opening facing down. The measuring device 2 can measure the length of the left vertical section of the sealing strip by sliding along the left vertical section of the slide rail 12. The measuring device 2 can measure the length of the top horizontal section of the sealing strip by sliding along the top horizontal section of the slide rail 12. And so on. The length of different sections of the sealing strip can be measured by using the slide rail 12 with the same shape as the sealing strip.

[0032] When measuring the length, first, the laser probe 23 is aligned with the measurement point at the first end of the section to be measured, and the value of the sensor head 22 is zeroed. Then, the measuring device 2 is slid so that the laser probe 23 is aligned with the measurement point at the second end of the section to be measured. The sensor head 22 will measure the distance moved by the measuring device 2 after being zeroed, which is the straight-line distance between the first end and the second end of the section to be measured. This is used to determine whether the size of the current measuring sealing strip section meets the requirements. Then, the above operation is repeated to measure the length of different sections of the sealing strip.

[0033] This fixture uses a slide rail 12 on the support frame 1 that matches the shape of the sealing strip, and the measuring device 2 is slidably mounted on the slide rail 12 to measure the length of different sections of the sealing strip. The length measurement of different sections of the sealing strip can be completed in a single assembly. There is no need to change the position or angle of the sealing strip or reassemble the sealing strip during measurement, which saves the process of measuring the sealing strip completely and reduces the probability of measurement errors caused by the adjustment of the sealing strip position.

[0034] In order to enable the laser probe 23 to be aligned with the measurement points at the first and second ends of the segment to be measured, such as Figure 2 As shown, two laser probes 23 are provided on the mounting bracket 21. The two laser probes 23 are distributed along the sliding direction of the sliding part, and there is a preset interval between the two laser probes 23 so that the two laser probes 23 extend beyond the left and right sides of the sliding part, respectively.

[0035] use Figure 2 To explain, the laser probe 23 located on the left side of the sliding part is used to align with the measurement point at the left end of the horizontal segment of the sealing strip, while the laser probe 23 located on the right side of the sliding part is used to align with the measurement point at the right end of the horizontal segment of the sealing strip. Similarly, when reading the final value of the sensing head 22, the straight-line distance between the two laser probes 23 must be added. By setting the interval between the two laser probes 23, the measurement range of the laser probes 23 is increased, thereby increasing the measurement range of the measuring device 2, so as to ensure that the measuring device 2 has sufficient measurement stroke.

[0036] There are many ways to increase the measurement range of the measuring device 2. For example, the laser probe 23 can be movably mounted on the mounting bracket 21. The laser probe 23 can be slidably mounted on the mounting bracket 21. When the laser probe 23 slides to the first position, it can be aligned with the measurement point at the first end. Then the laser probe 23 can be slid to the second position, and then the entire measuring device 2 can be slid to the second end. Then the laser probe 23 is aligned with the measurement point at the second end. Finally, when outputting the measurement result, the interval when the laser probe 23 moves from the first position to the second position needs to be added to ensure the accuracy of the final result.

[0037] The slide rail 12 is set according to the shape of the sealing strip. That is to say, the slide rail 12 has areas for measuring different sections of the sealing strip. These areas on the slide rail 12 for measuring different sections of the sealing strip are called measurement sections.

[0038] In some examples, the measurement segments are rounded to allow the measuring device 2 to slide and switch between adjacent measurement segments. This allows the measuring device 2 to slide to the next measurement segment to measure the sealing strip after measuring the sealing strip in the current measurement segment. The slide rail 12 and the sliding part are set in a conventional technical manner in the art. An example of the slide rail 12 and the sliding part is given below.

[0039] like Figure 3 As shown, in this example, the slide rail 12 protrudes beyond the surface of the support frame 1, as... Figure 4 The sliding part shown includes two clamping wheels 24 and a base 25 for mounting the two clamping wheels 24. The two clamping wheels 24 are rotatably mounted on the base 25 along their own axis of rotation, and the distance between the two clamping wheels 24 matches the width of the slide rail 12, so that the two clamping wheels 24 can clamp the slide rail 12 on both sides to achieve sliding cooperation with the slide rail 12. By controlling the distance between the clamping wheels 24, the two clamping wheels 24 can be clamped on both sides of the slide rail 12, and the clamping wheels 24 can rotate, so that the measuring device 2 can move along the slide rail 12. Since the measurement segment is a circular arc transition, and the thickness of the circular arc transition area is the same as the thickness of the measurement segment area, the two clamping wheels 24 can smoothly pass through the circular arc transition position between the measurement segments, so that they can move and switch freely between the measurement segments. The operation is simple and convenient.

[0040] Furthermore, the slide rail 12 has a retaining edge, and there are protruding parts on both sides or one side of the top of the slide rail 12. After the two clamping wheels 24 are clamped on both sides of the slide rail 12, the protruding part at the top of the slide rail 12 can be used to limit the clamping wheels 24, prevent the clamping wheels 24 from detaching from the top of the slide rail 12, ensure the stability of the measuring device 2 during the measurement process, and prevent the measuring device 2 from detaching from the slide rail 12, which would lead to inaccurate measurement results or damage to the measuring device 2.

[0041] In some examples, the sliding part and different measuring sections on the slide rail 12 can be detached and installed so that the sliding part can slide and engage with different measuring sections on the slide rail 12. After measuring the sealing strip in the current measuring section, the measuring device 2 can be detached from the current measuring section and then reassembled to other measuring sections for measurement, thereby realizing the switching between different measuring sections. The detachable engagement of the sliding part and the slide rail 12 is a conventional technical means in this field. Two examples of the detachable engagement of the sliding part and the slide rail 12 are given below.

[0042] like Figure 2 and Figure 5As shown, in the first example, one of the slide rail 12 and the sliding part is made of magnetic metal, and the other is made of magnet. This allows the sliding part to be attracted to the slide rail 12 and slide along it. Utilizing the property of magnets to attract magnetic metals, the sliding part can be attracted to the slide rail 12 and move along it. Simultaneously, the sliding part can be directly separated from the slide rail 12 under external force. This makes it simple and convenient to use. Specifically, as shown... Figure 2 As shown, the slide rail 12 is a groove formed on the support frame 1, and the sliding part is a slider 28 made of magnet. The support frame 1 is made of magnetic metal, so that the slider 28 made of magnet can be attracted in the groove, and the size of the groove and the slider 28 are matched, so that the slider 28 can slide in the groove, realizing the sliding cooperation between the sliding part and the slide rail 12.

[0043] like Figure 6 As shown, in the second example, the slide rail 12 protrudes outward from the support frame 1. The sliding part includes a base 25 and two clamping blocks 26 disposed on the base 25. At least one of the two clamping blocks 26 is elastically slidably disposed on the base 25 so that the distance between the two clamping blocks 26 is adjustable. By clamping the two clamping blocks 26 on the slide rail 12, the sliding part can slide along the slide rail 12. When it is necessary to remove the sliding part from the slide rail 12, the movable clamping block 26 on the base 25 is manually moved to increase the distance between the two clamping blocks 26, thereby allowing the sliding part to detach from the slide rail 12.

[0044] Furthermore, the side of the slide rail 12 has grooves or protrusions that fit with the clamping blocks 26, so that the clamping blocks 26 cannot be disengaged from the top of the slide rail 12 after being clamped to both sides of the slide rail 12, ensuring the stability of the sliding part when sliding on the slide rail 12. As shown in the figure, the slide rail 12 has a T-shaped cross section, and the lower end of the clamping block 26 has a protruding part on the side facing the slide rail 12. When the two clamping blocks 26 are clamped to both sides of the slide rail 12, the protruding part of the clamping block 26 can be inserted into the inner side of the lower end of the slide rail 12, thereby preventing the clamping blocks 26 from disengaging from the slide rail 12.

[0045] The clamping block 26 is elastically slidable on the base 25. Figure 6 An example is given in which a spring is provided under the base, the free end of the spring is fixedly connected to the clamping block 26, and the clamping block 26 is slidably engaged with the base 25 through a slide rod, thereby realizing the elastic sliding setting of the clamping block 26 on the base 25.

[0046] Specifically, the door frame sealing strip length measuring fixture also includes a stand 3, on which a mounting panel 31 for mounting the support frame 1 is provided. The mounting panel 31 is inclined or perpendicular to the horizontal plane, and the support frame 1 is fixed to the inclined upward side or the perpendicular side of the mounting panel 31.

[0047] like Figure 1 As shown, in this example, the mounting panel 31 is inclined to the horizontal plane. After the support frame 1 is fixedly set on the inclined upward side of the mounting panel 31, the mounting panel 31 can be used to support the sealing strip. The support surface 11 on the support frame 1 is used to support the sealing strip from the inside, while the mounting panel 31 is used to support the sealing strip from the side. This ensures the stability of the sealing strip after it is placed on the support frame 1, ensures that the sealing strip will not shake during the measurement process, and guarantees the accuracy of the final measurement.

[0048] like Figure 2 As shown, a handle 27 is further fixedly provided on the mounting bracket 21, which allows the measuring device 2 to be moved as a whole.
