[0024] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:
[0025] like Figure 1-4 As shown, the thermal detector of the utility model comprises an observation handle 1, a relay line 4, a protective shell 5 and a detection assembly 8. A display screen 2 is inlaid and fixed on the upper end of the observation handle 1, a switch button 3 is arranged on the upper middle part of the observation handle 1, a threaded rod 6 is installed on the inner side of the left end of the protective shell 5, a fixing block 7 is fixedly connected to the left rear inner wall of the protective shell 5, a detection assembly 8 is arranged on the inner side of the protective shell 5, a closed protection assembly 9 is installed above the detection assembly 8, and a relay line 4 is connected between the detection assembly 8 and the observation handle 1.
[0026] On the basis of the above structure, the protective shell 5 and the threaded rod 6 are connected in a bearing connection, and one end of the threaded rod 6 located inside the protective shell 5 is rotatably connected to the fixing block 7 .
[0027] In this embodiment, the threaded rod 6 is used to facilitate the sliding adjustment of the detection assembly 8 .
[0028] Based on the above structure, the detection assembly 8 includes a movable seat 81, a fixed column 82 and a sensor probe 83. The movable seat 81 is slidably located on the inner side of the protective shell 5. The fixed column 82 is welded and fixed at the middle position of the upper end of the movable seat 81, and the sensor probe 83 is embedded and fixed at the rear of the right end of the movable seat 81.
[0029] In this embodiment, the movable seat 81 is used to facilitate the sensor probe 83 to be retracted into the protective shell 5 when idle, so that the sensor probe 83 can be well isolated and protected to avoid damage that affects the detection accuracy.
[0030] On the basis of the above structure, one end of the relay line 4 away from the observation handle 1 passes through the protective shell 5 and is movably connected to the protective shell 5 , and one end of the relay line 4 located inside the protective shell 5 is electrically connected to the sensor probe 83 .
[0031] In this embodiment, the detection data of the sensor probe 83 is conveniently transmitted to the observation handle 1 through the relay line 4, and the data is displayed through the display screen 2.
[0032] On the basis of the above structure, the closed protection component 9 includes a cross bar 91, a movable plate 92, a guide groove 93, a connecting rod 94 and a sealing plate 95. The two cross bars 91 are respectively fixedly installed on the inner sides of the front and rear ends of the protective shell 5, and the front and rear ends of the movable plate 92 are respectively slidably mounted on the outer sides of the two cross bars 91. A guide groove 93 is opened in the middle of the movable plate 92. A connecting rod 94 is fixed to the right rear of the movable plate 92, and a sealing plate 95 is fixedly connected to the rear of the connecting rod 94. The sealing plate 95 is slidably located on the inner side of the rear end of the protective shell 5.
[0033] In this embodiment, the cross bar 91 can improve the stability of the movable plate 92, the connecting rod 94 and the sealing plate 95 during sliding, and the rear end opening of the protective shell 5 can be closed by the cooperation between the fixed block 7 and the sealing plate 95.
[0034] On the basis of the above structure, the top guide slide of the fixed column 82 is located in the guide groove 93, and the guide groove 93 includes an inclined section and a straight section located behind the inclined section, and the inclined section is connected to the straight section.
[0035] In this embodiment, the guide groove 93 is provided to facilitate the sliding of the movable plate 92 under the moving and squeezing action of the fixed column 82 .
[0036] Based on the above structure, the sum of the lengths of the sealing plate 95 and the fixing block 7 is greater than the inner width of the protective shell 5 .
[0037] In this embodiment, it is convenient to fully seal the rear end opening of the protective shell 5 and to efficiently isolate and protect the sensor probe 83.
[0038] The working principle of the utility model is as follows:
[0039] After the use of the thermal detector is completed, the threaded rod 6 can be manually rotated to control the movable seat 81 to drive the sensor probe 83 to move and retract toward the inside of the protective shell 5. At this time, the fixed column 82 moves along the straight section of the guide groove 93, so the movable plate 92 is in a stationary state. When the rear end of the sensor probe 83 moves into the protective shell 5, the fixed column 82 moves to the bending part of the guide groove 93. As the threaded rod 6 continues to rotate and the detection assembly 8 continues to move, the fixed column 82 can squeeze the inclined section of the guide groove 93, so that the movable plate 92 is compressed and drives the connecting rod 94 and the sealing plate 95 to move stably to the right along the cross bar 91 synchronously. At this time, the sealing plate 95 can cooperate with the fixed block 7 to close the rear end opening of the protective shell 5, so that the sensor probe 83 can be well isolated and protected to prevent the sensor probe 83 from being damaged and affecting the detection accuracy.
[0040] It should be noted that when the sensor probe 83 is in the storage state, there is a reasonable gap between its rear end and the sealing plate 95 to ensure the stable opening and closing of the sealing plate 95 and avoid jamming. In addition, the basic product improved in this application is the TS-003-IELK thermocouple digital thermometer, which is mainly improved for the defect of lack of protection of this type of thermal detector. The circuit connection method, internal structure and specific working principle of the observation handle 1, display screen 2, switch button 3, relay line 4 and sensor probe 83 in this application are all existing technologies, so they will not be described in detail.
