Technical Field
[0001] This utility model relates to the field of suspension bracket technology, specifically to a side-suction fixed-point temperature and humidity standard meter suspension bracket. Background Technology
[0002] A temperature and humidity testing chamber is a device specifically designed to test the accuracy of temperature and humidity meters. It creates a constant temperature and humidity environment, and then places both a standard temperature and humidity meter and the meter to be tested inside. If the reading on the meter to be tested differs significantly from the reading on the standard meter, the meter is considered unqualified and cannot be used as a standard instrument for environmental testing.
[0003] In actual use, the temperature and humidity in each space of the temperature and humidity testing chamber may have large errors. For example, the temperature and humidity in the center of the chamber may be different from those at the edges. The standard temperature and humidity meter is mainly hung in the center of the chamber along with the temperature and humidity meter to be tested, and there is only one such meter. However, the temperature and humidity meter to be tested is hung in multiple places and distributed on the outside. This will cause errors when comparing the readings of the standard temperature and humidity meter with those of the meter to be tested, resulting in inaccurate test results. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a hanging bracket for a side-suction fixed-point temperature and humidity standard meter. By installing the screw inside the sleeve and rotating the nut to make it tightly abut against the stop plate, the left and right frames can be firmly fixed to the inner wall of the temperature and humidity detection box. This hanging bracket can hang the temperature and humidity standard meter at nine hanging points. The nine temperature and humidity standard meters are evenly distributed, which can more effectively ensure the accuracy of temperature and humidity detection.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:
[0006] A suspension bracket for a side-suction fixed-point temperature and humidity standard meter is disclosed. This bracket is used to suspend the temperature and humidity standard meter inside a temperature and humidity testing chamber. It includes a vertically arranged left frame and a vertically arranged right frame. Suspension rods are welded to the four corners of both the left and right frames, and suction cup feet are bonded to the ends of each suspension rod. A horizontally arranged, hollow sleeve is fixed to the center of the left frame, and a retaining plate is fixed to the end of the sleeve. A horizontally arranged screw rod is fixed to the center of the right frame, and a nut is threaded onto the screw rod.
[0007] By using the above solution, the screw is fitted into the sleeve, and by rotating the nut to make it tightly abut against the stop plate, the left and right frames can be firmly fixed to the inner wall of the temperature and humidity detection box. The hanging bracket can hang temperature and humidity standard gauges at nine hanging points. The nine temperature and humidity standard gauges are evenly distributed, which can more effectively ensure the accuracy of temperature and humidity detection.
[0008] In a preferred embodiment of the suspension bracket for a side-suction fixed-point temperature and humidity standard meter, both the left and right frames are grid-like frames.
[0009] To improve the stability of the left and right frames, the above scheme adopts a grid-like frame structure as the main frame, which has better stability and reliability when suspended.
[0010] In a preferred embodiment of the suspension bracket for a side-suction fixed-point temperature and humidity standard meter, each suspension rod has a cable tray fixed near the suction cup support foot, and the cable tray has an annular groove; an elastic rubber band is fitted together in the annular groove of each pair of upper and lower cable trays; wherein, the diameter of the cable tray is larger than the diameter of the suspension rod.
[0011] To avoid affecting the measurement results of the temperature and humidity standard meter, an elastic band is installed on the side wall near the temperature and humidity testing chamber using the above solution. This way, the temperature and humidity standard meter will not directly contact the side wall of the temperature and humidity testing chamber when it is suspended on the hanging rod, thus avoiding affecting the measurement results.
[0012] In a preferred embodiment of the suspension bracket for a side-suction fixed-point temperature and humidity standard meter, a suspension groove is provided on the body of the suspension rod.
[0013] By adopting the above solution, in order to ensure the stability of the temperature and humidity standard meter after it is suspended, it is suspended in the suspension groove, which can prevent the temperature and humidity standard meter from sliding after it is suspended.
[0014] In a preferred embodiment of the suspension bracket for a side-suction fixed-point temperature and humidity standard meter, two spaced-apart suspension protrusions are fixed on the upper outer side of the sleeve.
[0015] By adopting the above scheme, in order to ensure the stability of the temperature and humidity standard meter after it is suspended, it is suspended between two suspension protrusions, which can prevent the temperature and humidity standard meter from sliding after it is suspended.
[0016] In a preferred embodiment of the suspension bracket for a side-suction fixed-point temperature and humidity standard meter, two symmetrical throttles are welded and fixed on the outer wall of the nut.
[0017] By adopting the above solution, a throttle handle is provided to make it easier to rotate the nut, which will make it easier to rotate the nut.
[0018] In a preferred embodiment of the suspension bracket for a side-suction fixed-point temperature and humidity standard meter, the four suspension grooves on the left frame serve as four suspension points for the temperature and humidity standard meter, namely, points a, b, c, and d; the four suspension grooves on the right frame serve as four suspension points for the temperature and humidity standard meter, namely, points e, f, g, and h; and the two suspension protrusions on the sleeve serve as one suspension point for the temperature and humidity standard meter, namely, point i; a total of nine suspension points are provided.
[0019] To further reduce errors, the above scheme employs nine evenly distributed temperature and humidity standard meters to jointly calibrate the ambient temperature and humidity inside the temperature and humidity testing chamber. If the temperature and humidity values measured by the nine temperature and humidity standard meters are within a very small error range, it indicates that the environment inside the temperature and humidity testing chamber is constant, and the results of subsequent measurements on the temperature and humidity testing meters will be more accurate.
[0020] After adopting the above technical solution, the beneficial effects of this utility model are:
[0021] 1. Install the screw into the sleeve, and rotate the nut to make it tightly abut against the stop plate. This will firmly fix the left and right frames to the inner wall of the temperature and humidity detection box. The hanging bracket can hang temperature and humidity standard gauges at nine hanging points. The nine temperature and humidity standard gauges are evenly distributed, which can more effectively ensure the accuracy of temperature and humidity detection.
[0022] 2. To improve the stability of the left and right frames, a grid-like frame structure is used as the main frame, which has better stability and reliability when suspended.
[0023] 3. To avoid affecting the measurement results of the temperature and humidity standard meter, an elastic band is installed on the side wall near the temperature and humidity testing chamber. This way, the temperature and humidity standard meter will not directly contact the side wall of the temperature and humidity testing chamber when it is suspended on the hanging rod, thus avoiding affecting the measurement results.
[0024] 4. To ensure the stability of the temperature and humidity standard meter after it is suspended, it is suspended in the hanging groove to prevent the temperature and humidity standard meter from sliding after it is suspended.
[0025] 5. To ensure the stability of the temperature and humidity standard meter after it is suspended, it should be suspended between two suspension protrusions to prevent the temperature and humidity standard meter from slipping after it is suspended.
[0026] 6. To further reduce errors, nine evenly distributed temperature and humidity standard meters are used to jointly calibrate the ambient temperature and humidity inside the temperature and humidity testing chamber. If the temperature and humidity values measured by the nine temperature and humidity standard meters are within a very small error range, it indicates that the environment inside the temperature and humidity testing chamber is constant, and the results of subsequent measurements of the temperature and humidity meter will be more accurate.

Detailed Implementation
[0038] 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.
[0039] like Figures 1 to 8 As shown, a side-suction fixed-point temperature and humidity standard meter hanger is used to suspend the temperature and humidity standard meter inside a temperature and humidity detection chamber 13. It includes a vertically arranged left frame 1 and a vertically arranged right frame 2. Suspension rods 3 are welded to the four corners of both the left and right frames 1 and 2, and suction cup feet 4 are bonded to the end of each suspension rod 3. A horizontally arranged, hollow sleeve 5 is fixed to the center of the left frame 1, and a stop plate 6 is fixed to the end of the sleeve 5. A horizontally arranged screw 7 is fixed to the center of the right frame 2, and a nut 8 is threaded onto the screw 7. By fitting the screw 7 into the sleeve 5 and rotating the nut 8 to tightly abut against the stop plate 6, the left and right frames 1 and 2 are firmly fixed to the inner wall of the temperature and humidity detection chamber 13. This hanger can suspend the temperature and humidity standard meter at nine evenly distributed points, which can more effectively ensure the accuracy of temperature and humidity detection.
[0040] like Figure 7 , Figure 7 As shown, both the left frame 1 and the right frame 2 are grid-like frames. To improve the stability of the left frame 1 and the right frame 2, a grid-like frame structure is used as the main frame, which provides better stability and reliability when suspended.
[0041] like Figure 3 As shown, each suspension rod 3 has a cable tray 9 fixed near the suction cup support 4, and the cable tray 9 has an annular groove. An elastic band 10 is fitted into the annular groove of each pair of upper and lower cable trays 9. The diameter of the cable tray 9 is larger than the diameter of the suspension rod 3. To avoid affecting the measurement results of the temperature and humidity standard meter, an elastic band 10 is added near the side wall of the temperature and humidity detection box 13. This prevents the temperature and humidity standard meter from directly contacting the side wall of the temperature and humidity detection box 13 while suspended on the suspension rod 3, thus avoiding interference with the measurement results.
[0042] like Figure 3 As shown, a suspension groove 11 is provided on the rod of the suspension rod 3. In order to ensure the stability of the temperature and humidity standard meter after it is suspended, it is suspended in the suspension groove 11 to avoid the temperature and humidity standard meter from slipping after it is suspended.
[0043] like Figure 6As shown, two spaced-apart suspension protrusions 12 are fixed on the upper outer side of the sleeve 5. To ensure the stability of the temperature and humidity standard meter after it is suspended, it is suspended between the two suspension protrusions 12 to prevent the temperature and humidity standard meter from slipping after it is suspended.
[0044] like Figure 4 As shown, two symmetrical handles are welded and fixed to the outer wall of the nut 8. The handles make it easier to rotate the nut 8, requiring less effort.
[0045] like Figure 9 As shown, the four hanging grooves 11 on the left frame 1 serve as four hanging points for the temperature and humidity standard gauges, namely points a, b, c, and d; the four hanging grooves 11 on the right frame 2 serve as four hanging points for the temperature and humidity standard gauges, namely points e, f, g, and h; and the two hanging protrusions 12 on the sleeve 5 serve as one hanging point for the temperature and humidity standard gauge, namely point i. A total of nine hanging points are provided. To further reduce errors, nine evenly distributed temperature and humidity standard gauges are used to jointly calibrate the ambient temperature and humidity inside the temperature and humidity testing chamber 13. If the temperature and humidity values measured by the nine temperature and humidity standard gauges are within a very small error range, it indicates that the environment inside the temperature and humidity testing chamber 13 is constant, and the results of subsequent measurements of the temperature and humidity gauges will be more accurate.
[0046] The working principle of this utility model:
[0047] Before application, first install the screw 7 into the sleeve 5, then place the left frame 1 and the right frame 2 together into the temperature and humidity detection chamber 13. By rotating the nut 8 and making it tightly abut against the stop plate 6, the left frame 1 and the right frame 2 can be firmly fixed to the inner wall of the temperature and humidity detection chamber 13.
[0048] In application, nine temperature and humidity standard meters are suspended sequentially at suspension point ai. The environment temperature and humidity inside the temperature and humidity detection chamber 13 are calibrated by using nine evenly distributed temperature and humidity standard meters. If the temperature and humidity values measured by the nine temperature and humidity standard meters are within a very small error range, it indicates that the environment inside the temperature and humidity detection chamber 13 is constant. Then, the results of subsequent measurements of the temperature and humidity detection meters will be more accurate.
[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
