[0023] Reference Figure 1 As shown, the present invention provides a technical solution: a partition outlet area measurement system, comprising a wedge-shaped feeler gauge 10 and a mobile device 20, wherein the wedge-shaped feeler gauge 10 is used to measure the throat width of the partition outlet; the mobile device 20 is communicatively connected with the wedge-shaped feeler gauge 10, and the mobile device 20 is used to calculate the area of ​​the partition outlet using the throat width and the pre-input throat height.

[0024] Exemplarily, the mobile device 20 may be a computer device or the like.

[0025] In this embodiment, the wedge-shaped feeler gauge 10 communicates with the mobile device 20, and the throat width measured by the wedge-shaped feeler gauge 10 is promptly transmitted to the mobile device 20, so that the mobile device 20 can calculate the area of ​​the partition outlet in a timely manner. This can provide convenience for the staff and improve work efficiency.

[0026] Reference Figures 2~5 As shown, in some embodiments, the wedge-shaped feeler gauge 10 includes a gauge body 11, a digital display detector 12 and a positioning plate 13. The digital display detector 12 is provided with a sliding hole 121. The digital display detector 12 is slidably disposed on the gauge body 11 through the sliding hole 121. The positioning plate 13 is disposed on the digital display detector 12.

[0027] In this embodiment, during measurement, the positioning plate 13 is pressed against the outer wall of the partition outlet, and as the wedge-shaped measuring portion of the ruler body 11 continues to move deeper into the partition outlet, the positioning plate 13 pushes the digital display detector 12 to slide along the supporting portion of the ruler body 11. At the same time, the displacement sensor inside the digital display detector 12 detects the displacement of the digital display detector 12, thereby measuring the throat width of the partition outlet.

[0028] Reference Figures 3 to 6 As shown, in some embodiments, a reference protrusion 111 is provided at the starting point of the ruler body 11 , a first mounting hole 122 is formed on the side wall of the sliding hole 121 corresponding to the reference protrusion 111 , and a feedback component 123 is provided in the first mounting hole 122 .

[0029] In this embodiment, during the initialization of the digital display detector 12, the feedback component 123 contacts the reference protrusion 111, so that the feedback component 123 feeds back a reference signal to the digital display detector 12. Thus, the digital display detector 12 determines that it is at the starting point of the ruler body 11, ensuring the accuracy of the throat width measured by the digital display detector 12.

[0030] Reference Figure 4 and 6As shown in Figure 9, in some embodiments, the first mounting hole 122 has a first accommodating cavity 1221 and a second accommodating cavity 1222, and the feedback component 123 includes a push rod 1231, a first elastic member 1232, a first conductive sheet 1233 and a second conductive sheet 1234. The push rod 1231 is constructed in a cross shape, one end of the push rod 1231 contacts the reference protrusion 111, the first flange 12311 of the push rod 1231 is located in the first accommodating cavity 1221, and one end of the first elastic member 1232 abuts against the reference protrusion 111. On the first flange 12311 of the push rod 1231, the other end of the first elastic member 1232 abuts against the wall of the first accommodating cavity 1221 relative to the first flange 12311, the first conductive sheet 1233 and the second conductive sheet 1234 are both located within the second accommodating cavity 1222, the first conductive sheet 1233 is connected to the other end of the push rod 1231, the second conductive sheet 1234 is arranged opposite to the first conductive sheet 1233, and the contact point of the second conductive sheet 1234 is in contact with the contact point of the first conductive sheet 1233.

[0031] Exemplarily, the first conductive sheet 1233 may be connected to the positive electrode, and the second conductive sheet 1234 may be connected to the negative electrode; or, the first conductive sheet 1233 may be connected to the negative electrode, and the second conductive sheet 1234 may be connected to the positive electrode.

[0032] In this embodiment, when the feedback component 123 is in the working state, the first flange 12311 of the push rod 1231 squeezes the first elastic member 1232 to compress and deform, and at the same time, the first conductive sheet 1233 contacts the second conductive sheet 1234; that is, when the digital display detector 12 is initialized, when the digital display detector 12 receives the feedback signal that the first conductive sheet 1233 and the second conductive sheet 1234 are connected, it can be determined that the digital display detector 12 is at the starting point. When the feedback component 123 is not in the working state, the first elastic member 1232 maintains the original extended state, and there is a gap between the first conductive sheet 1233 and the second conductive sheet 1234.

[0033] Exemplarily, the first elastic member 1232 may be a spring or an elastic rubber ring.

[0034] Reference Figure 5 As shown, in some embodiments, a clearance groove 1211 is opened on the side wall of the sliding hole 121 , and the clearance groove 1211 is perpendicular to the first mounting hole 122 .

[0035] In this embodiment, when the digital display detector 12 returns to the starting point, the clearance groove 1211 can facilitate the passage of the reference protrusion 111. This not only makes the size of the sliding hole 121 adapt to the support portion of the ruler body 11 to ensure the stability of the movement of the digital display detector 12, but also avoids interference between the reference protrusion 111 and the sliding hole 121.

[0036] Reference Figure 6 and 10As shown, in some embodiments, a limiting hole 112 parallel to the reference protrusion 111 is formed on the ruler body 11, a second mounting hole 124 is formed on the side wall of the sliding hole 121 corresponding to the limiting hole 112, and a limiting component 125 is disposed in the second mounting hole 124.

[0037] In this embodiment, when the digital display detector 12 is in the initialization state, the limiting assembly 125 cooperates with the limiting hole 112 to limit the digital display detector 12 to prevent the digital display detector 12 from accidentally moving and affecting the verification of the starting point.

[0038] Reference Figure 6 and 10 ~As shown in FIG11, in some embodiments, the second mounting hole 124 has a third accommodating cavity 1241 and a fourth accommodating cavity 1242, the limiting assembly 125 includes a limiting rod 1251, a second elastic member 1252, a first magnetic member 1253 and a second magnetic member 1254, the limiting rod 1251 is constructed in a cross shape, one end of the limiting rod 1251 is inserted into the limiting hole 112, the second flange 12511 of the limiting rod 1251 is located in the third accommodating cavity 1241, one end of the second elastic member 1252 abuts against the second flange 12511, and the other end of the second elastic member 1252 abuts against the wall of the fourth accommodating cavity 1242 relative to the second flange 12511, the first magnetic member 1253 and the second magnetic member 1254 are both located in the fourth accommodating cavity 1242, the first magnetic member 1253 is connected to the other end of the limiting rod 1251, and the second magnetic member 1254 is arranged opposite to the first magnetic member 1253.

[0039] For example, the second elastic member 1252 may be a spring or an elastic rubber ring, etc. The first magnetic member 1253 and the second magnetic member 1254 may both be electromagnets, etc.

[0040] In this embodiment, when the limiting assembly 125 is in the limiting state, the first magnetic member 1253 and the second magnetic member 1254 do not work and there is a gap between them, the second elastic member 1252 maintains the original extended state, and the limiting rod 1251 is inserted into the limiting hole 112. That is to say, when the digital display detector 12 is at the starting point, the limiting rod 1251 cooperates with the limiting hole 112 to limit the digital display detector 12, so that the digital display detector 12 can be prevented from being moved. When the limiting assembly 125 is in the non-limiting state, the first magnetic member 1253 and the second magnetic member 1254 are both energized, so that the first magnetic member 1253 and the second magnetic member 1254 are attracted to each other, the second flange 12511 of the limiting rod 1251 squeezes the second elastic member 1252 to compress and deform, and the limiting rod 1251 is separated from the limiting hole 112. Thus, the digital display detector 12 can be moved.

[0041] Reference Figure 3~4As shown, in some embodiments, a positioning protrusion 113 is provided at the connection between the wedge-shaped measuring portion and the supporting portion of the ruler body 11.

[0042] In this embodiment, when the digital display detector 12 is feeding back, the positioning protrusion 113 can play a role in positioning the digital display detector 12 to ensure that the digital display detector 12 can accurately return to the starting point.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
