DETAILED DESCRIPTION

[0022] The embodiment of the present application provides a sensor probe protection device, the main technical solution of which is that by providing a protective outer cylinder 4, a protective inner cylinder 5 and a sealing cover 6, the sensor probe 2 can be covered and protected, effectively solving the problem of damage caused by the sensor probe 2 being exposed to the outside world for a long time;

[0023] At the same time, by arranging a slide groove 41, an upper limit groove 42 and a lower limit groove 43 on the inner side of the protective outer tube 4, and arranging limit blocks 51 at both ends of the outer surface of the protective inner tube 5, the limit blocks 51 slide in the slide groove 41, the upper limit groove 42 and the lower limit groove 43, so as to realize the rapid deployment or folding of the protective inner tube 5, thereby providing convenience for the use or storage protection of the sensor probe 2.

[0024] Example: Refer to Figure 1 - Figure 5 As shown, a sensor probe protection device of the present embodiment includes a sensor body 1 and a sensor probe 2, and a protection component is arranged on the periphery of the sensor probe 2; the protection component includes a protection outer tube 4, and a protection inner tube 5 is arranged in the inner middle part of the protection outer tube 4, and a sealing cover 6 is arranged on the top of the protection inner tube 5. The periphery of the sensor probe 2 can be covered and protected by the protection outer tube 4 and the protection inner tube 5, and the sealing cover 6 can cover and seal the top opening of the protection inner tube 5, so as to realize the sealed storage of the sensor probe 2, play a protective role, and effectively solve the problem that the sensor probe 2 is easily damaged due to being exposed to the air for a long time.

[0025] Slide grooves 41 are provided at both ends of the inner side of the protective outer cylinder 4, and limit blocks 51 are provided on the lower sides of both ends of the protective inner cylinder 5. The limit blocks 51 are slidably installed in the middle part of the inner side of the slide groove 41. An upper limit groove 42 and a lower limit groove 43 are respectively provided at both ends of the slide groove 41. The limit blocks 51 are slidably connected with the upper limit groove 42 and the lower limit groove 43. The inlet ends of the upper limit groove 42 and the lower limit groove 43 are respectively connected with the two end ports of the slide groove 41, and the inner sides of the slide groove 41, the upper limit groove 42 and the lower limit groove 43 are all semicircular structures.

[0026] The position of the protective inner tube 5 can be adjusted up and down or rotated by sliding the limit block 51 in the slide groove 41 , the upper limit groove 42 and the lower limit groove 43 , so that the staff can unfold or fold the protective inner tube 5 conveniently.

[0027] In addition, a limiting protrusion 44 is provided on the inner side of the upper limiting groove 42 and the lower limiting groove 43 near the end position. The limiting protrusion 44 can limit the limiting block 51, thereby improving the stability of the protective inner tube 5 when it is unfolded or retracted, and preventing the protective inner tube 5 from sliding freely, which would affect the use of the sensor probe 2.

[0028] One end of the sealing cover 6 is hinged to the protective inner tube 5 and is magnetically adsorbed on the top opening of the protective inner tube 5, so that the sensing probe 2 can easily push open the sealing cover 6. When the sensing probe 2 is retracted, the sealing cover 6 can be used to cover and seal the top opening of the protective inner tube 5.

[0029] A movable plate 61 is arranged at the inner bottom of the sealing cover 6 , and multiple groups of springs 62 are arranged between the sealing cover 6 and the movable plate 61 , which play the role of elastic buffering; a soft cushion 63 is arranged in the middle of the bottom end of the movable plate 61 .

[0030] When the sensing probe 2 lifts the sealing cover 6 , the cushion 63 and the spring 62 both play a protective role, preventing the sensing probe 2 from making hard contact with the sealing cover 6 and causing damage to the sensing probe 2 .

[0031] In some examples, a flange 3 is provided at the middle of the bottom end of the protective outer tube 4, and the protective outer tube 4 is fixedly connected to the sensor body 1 through the flange 3. The flange 3 acts as a mounting carrier, so that the protective outer tube 4 can be installed on the sensor body 1 to provide peripheral covering and protection for the sensor probe 2.

[0032] The working principle of the utility model is:

[0033] When the sensing probe 2 needs to be used, the protective inner cylinder 5 is first rotated to make the limit block 51 slide from the upper limit groove 42 to the slide groove 41, and then the protective inner cylinder 5 is pushed downward to make the sensing probe 2 push open the sealing cover 6 and then extend out from the upper end of the protective inner cylinder 5, so that the sensing probe 2 can be used conveniently;

[0034] During this process, the protective inner cylinder 5 continues to slide down until the limit block 51 slides to the bottom of the slide groove 41. At this time, the protective inner cylinder 5 is rotated to make the limit block 51 slide into the lower limit groove 43 until it slides to the end position of the lower limit groove 43 and stops. At this time, the protective inner cylinder 5 is in a retracted state.

[0035] In addition, a limiting protrusion 44 is provided on the inner side of the upper limiting groove 42 and the lower limiting groove 43 near the end position, and the limiting protrusion 44 can limit the limiting block 51, thereby improving the stability of the protective inner tube 5 when it is in the retracted state.

[0036] In addition, when the protective inner tube 5 is pressed downward, the soft pad 63 at the inner bottom of the sealing cover 6 will first contact the top of the sensor probe 2. The soft pad 63 will push the movable plate 61 under force, and then generate thrust on the multiple sets of springs 62, and then continue to push the sealing cover 6, so that the sealing cover 6 is opened. In this process, the soft pad 63 and the multiple sets of springs 62 both play the role of elastic buffering, avoiding hard contact between the sensor probe 2 and the sealing cover 6, which would cause damage to the sensor probe 2.

[0037] On the contrary, by rotating the protective inner cylinder 5, the limit block 51 slides from the lower limit groove 43 to the slide groove 41, and then the protective inner cylinder 5 is pulled, and then the protective inner cylinder 5 is rotated, so that the limit block 51 slides to the end position of the upper limit groove 42. At this time, the protective inner cylinder 5 is in an expanded state, thereby realizing sealing protection for the sensor probe 2, avoiding the sensor probe 2 from being exposed to the outside when not in use and causing damage.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
