Description

Technical Field

[0001] The utility model relates to the technical field of thermometers, in particular to a shock-proof thermometer. Background Art

[0002] Resistance thermometers are divided into metal resistance thermometers and semiconductor resistance thermometers, both of which are made based on the characteristic that the resistance value changes with temperature. Metal thermometers mainly use pure metals such as platinum, gold, copper, nickel, etc. and rhodium iron and phosphor bronze alloys; semiconductor thermometers mainly use carbon, germanium, etc. Resistance thermometers are convenient and reliable to use and have been widely applied. Its measurement range is about -260°C to 600°C.

[0003] The existing Chinese utility model patent with the reference publication number of CN204630677U discloses a thermometer, which includes a temperature sensing component, a temperature display screen, a main housing for installing the temperature display screen, and a protective cover. The protective cover includes a left shell and a right shell located on both sides of the temperature sensing component. The left shell and the right shell are respectively rotatably installed on the main housing and are closed by rotation to cover the temperature sensing component. The above thermometer covers the temperature sensing component through the protective cover to better protect the thermometer and avoid damage. Since the left and right shells are rotatably installed on the main housing, when the two are rotated and opened, the thermometer is exposed for temperature measurement, and the rotated and opened left and right shells can be used as brackets to hang on the appliance without holding the thermometer by hand. Moreover, the rotated and opened left and right shells can also be used as handles to extend the length of the thermometer, making it more convenient to use.

[0004] Traditional thermometers with junction boxes are not vibration-resistant due to the large weight of the junction boxes, and it is very easy to cause wear and breakage of the thermometer leads, resulting in a high temperature display or a broken wire, thus triggering the interlock shutdown of the thermometer and causing shutdown losses. At the same time, the junction box of the thermometer is fixed to one end of the probe, resulting in uneven overall weight distribution. The inertia on the side of the junction box is large, and the probe of the thermometer may be bent or even broken during vibration. Summary of the Utility Model

[0015] Compared with the prior art, the present utility model provides a shock-proof thermometer, which has the following beneficial effects:

[0016] 1. The utility model separates the probe from the junction box through a split design by setting a connecting wire. The outside of the probe is an aluminum shell, and a thermistor is arranged inside. An ammeter is installed inside the junction box.

The thermistor inside the probe and the ammeter inside the junction box are connected in series through the connecting wire to detect the temperature. Since the weight of the probe is evenly distributed, the position of the probe is fixed by a fixing plate during use. The connecting wire can avoid the influence of the inertia of the junction box on the probe during vibration, thus preventing the probe from bending during vibration due to uneven weight distribution.

[0026] Please refer to Figure 1 - Figure 4 , in this embodiment, a shock-proof thermometer includes: a connecting plate 1, a limiting column 11 is fixedly installed in the center of the connecting plate 1, a slider 12 is inserted and installed on the outside of the limiting column 11, a damping rod 13 is fixedly installed above the slider 12, a support spring 14 is inserted and installed on the outside of the damping rod 13, a junction box 15 is fixedly installed on the left side of the slider 12, a connecting ring 16 is fixedly installed below the junction box 15, a limiting spring 17 is fixedly installed below the connecting ring 16, a connecting wire 18 is fixedly installed below the junction box 15, a probe 19 is fixedly installed at the front end of the connecting wire 18, and a fixing plate 110 is fixedly installed on the outside of the probe 19.

[0027] Rectangular protrusions are provided on the upper and lower sides of the connecting plate 1 and extend to the left. The limiting column 11 is fixedly installed at the center of the protruding structures on the upper and lower sides of the connecting plate 1. Openings are provided at the four corners of the connecting plate 1.

[0028] A sliding connection is formed between the slider 12 and the limiting column 11. The damping rods 13 are symmetrically installed above and below the slider 12 in a vertically mirror-image and front-back symmetrical manner with the center of the slider 12 as the reference.

[0029] The fixed end of the damping rod 13 is fixedly connected to the connecting plate 1, and the movable end of the damping rod 13 is fixedly connected to the slider 12.

[0030] The support spring 14 is located between the slider 12 and the connecting plate 1. The junction box 15 is movably connected to the connecting plate 1 through the slider 12.

[0031] The connecting wire 18 is fixedly connected between the connecting ring 16 and the junction box 15. The connecting wire 18 is fixedly connected to the inner wall of the connecting ring 16. The connecting rings 16 are symmetrically installed at the front and rear ends of the connecting wire 18.

[0032] The top end of the probe 19 is also fixedly installed with a connecting ring 16. The limiting springs 17 are fixed to both ends of the connecting wire 18 through the connecting rings 16.

[0033] Specifically, the connecting plate 1 can limit the position of the limiting column 11. The limiting column 11 can limit the movement direction of the slider 12. The slider 12 can facilitate the change of the relative position between the junction box 15 and the connecting plate 1. The damping rod 13 can absorb part of the force generated by vibration. The supporting spring 14 can play a shock-absorbing effect. The junction box 15 can facilitate the connection between the thermometer and the device. The connecting ring 16 can limit the position of the limiting spring 17. The limiting spring 17 can increase the arc generated by the bending at both ends of the connecting wire 18. The connecting wire 18 can facilitate the connection between the probe 19 and the junction box 15. The probe 19 can detect temperature. The fixing plate 110 can limit the position of the probe 19 through bolts.

[0034] When in use, the probe 19 and the junction box 15 are separated through a split design. The exterior of the probe 19 is an aluminum shell, and a thermistor is arranged inside. An ammeter is installed inside the junction box 15.

The thermistor inside the probe 19 and the ammeter inside the junction box 15 are connected in series through the connecting wire 18 to detect temperature. Since the weight distribution of the probe 19 is uniform, the position of the probe 19 is fixed through the fixing plate 110 during use. The connecting wire 18 can prevent the inertia of the junction box 15 from affecting the probe 19 during vibration, thereby avoiding the situation that the probe 19 is bent during vibration due to uneven weight distribution. The slider 12 is fixedly connected to the junction box 15. The slider 12 is inserted and installed outside the limiting column 11.

The fixed end of the damping rod 13 is fixedly connected to the connecting plate 1, and the movable end of the damping rod 13 is fixedly connected to the slider 12. The supporting spring 14 is located between the slider 12 and the connecting plate 1. The junction box 15 is movably connected to the connecting plate 1 through the slider 12. This method can enable relative displacement between the connecting plate 1 and the junction box 15. During vibration, the junction box 15 moves up and down, so that the damping rod 13 switches between the extended and contracted states to absorb the force generated by vibration, thereby reducing the impact of vibration on the internal circuit of the junction box 15.
