The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0028] Reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, and this embodiment provides a standard microwave level detection switch. The standard microwave level detection switch includes a main body component 100 and an adjustment component 200. Through the cooperation of the two, the position of the probe 104 can be adjusted, and the insert 103 can be fixed to prevent the insert 103 from loosening, thereby improving the stability of the microwave level detection switch.

[0029] Specifically, the main assembly 100 includes a threaded column 101 , an explosion-proof junction box 102 , a plug 103 and a probe 104 . The explosion-proof junction box 102 is fixed to the end of the threaded column 101 , the plug 103 is fixed to the other end of the threaded column 101 , and the probe 104 is fixed to the end of the plug 103 .

[0030] The threaded column 101 is used to fix and support the explosion-proof junction box 102 and the plug body 103. The explosion-proof junction box 102 is a sealed box, usually made of cast metal, with explosion-proof function and meets explosion-proof requirements. The plug body 103 and the probe 104 are existing technologies and are key components for microwave transmission and reception. They are responsible for generating and sending microwave signals, and are also responsible for receiving microwave signals reflected from the surface of the material. These signals are then converted into electrical signals, which are then used to determine the position and height of the material.

[0031] The adjustment component 200 is arranged on the surface of the threaded column 101, and includes a fixing member 201, an adjustment member 202 and a limiting member 203. The fixing member 201 is arranged on the surface of the threaded column 101, the adjustment member 202 is arranged on one side of the fixing member 201, and the limiting member 203 is located on the fixing member 201.

[0032] The fixing part 201 is used to fix and install the standard microwave level detection switch. The adjusting part 202 can adjust the position of the standard microwave level detection switch and fix the position of the fixing part 201 to prevent the insert 103 from loosening and improve the stability of the microwave level detection switch. The limiting part 203 is used to limit the adjusting part 202.

[0033] Specifically, the fixing member 201 includes a fixing plug plate 201 a and a fixing nut 201 b . The fixing plug plate 201 a is disposed on the surface of the threaded column 101 , and the fixing nut 201 b is rotatably connected to the surface of the threaded column 101 through threads.

[0034] By rotating the fixing nut 201b, the fixing nut 201b and the insert body 103 can simultaneously press the fixing plug plate 201a, so that the microwave level detection switch is fixed on the fixing plug plate 201a.

[0035] Specifically, the fixing member 201 further includes a fixing ring 201c, which is fixed to the surface of the insert body 103. A slot U is provided at the bottom of the fixing insert plate 201a, and the fixing ring 201c is located in the slot U.

[0036] The fixing ring 201c can limit the position of the inserting body 103 by being engaged in the slot U, so that the inserting body 103 will not slide on the fixing inserting plate 201a.

[0037] Specifically, the fixing member 201 further includes a fixing column 201d, which is fixed to the bottom of the fixing plug plate 201a. A fixing groove V is formed on the surface of the fixing ring 201c, and the fixing column 201d is located in the fixing groove V.

[0038] The fixing column 201d is used to limit the angle of the fixing ring 201c so that the fixing ring 201c does not rotate. Example

[0039] Reference Figure 1~Figure 3 , Figure 5 and Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0040] Specifically, the adjusting member 202 includes a slider 202a and a mounting plate 202b. The slider 202a slides in the fixed plug plate 201a, and the mounting plate 202b is fixed to the surface of the slider 202a.

[0041] By adjusting the position of the slider 202a, the position of the fixed plug plate 201a can be adjusted. The mounting plate 202b is used to fix and support the slider 202a. The mounting plate 202b is provided with mounting holes to facilitate fixing the mounting plate 202b.

[0042] Specifically, the adjusting member 202 further includes an insert rod 202c, which slides in the slider 202a. A slot W is provided in the fixed insert plate 201a, and an end of the insert rod 202c is inserted into the slot W.

[0043] The insertion rod 202c is inserted into the slot W to fix the position of the fixed plugboard 201a. There are multiple slots W in the fixed plugboard 201a.

[0044] Specifically, the adjusting member 202 further includes a driving column 202d and a protrusion 202e. The driving column 202d is rotatably connected to the slider 202a, and the protrusion 202e is fixed to the surface of the driving column 202d.

[0045] By rotating the driving column 202d, the driving column 202d can drive the protrusion 202e to press the insertion rod 202c, so that the insertion rod 202c is inserted into the slot W. Example

[0046] Reference Figures 1 to 3 , Figure 5 and Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0047] Specifically, the adjusting member 202 further includes a supporting block 202f and a first spring 202g. The supporting block 202f is fixed to the inner wall of the sliding block 202a, and the end of the first spring 202g is fixed to one side of the supporting block 202f.

[0048] The support block 202f is used to fix and support the first spring 202g. The first spring 202g is in a compressed state. The return elastic force of the first spring 202g can move the insertion rod 202c out of the slot W, thereby releasing the limit on the fixed insertion plate 201a.

[0049] Specifically, the adjustment member 202 further includes a swing rod 202h, which is fixed to the top of the driving column 202d. A limiting groove X is provided on the surface of the fixing nut 201b, and an end of the swing rod 202h is located in the limiting groove X.

[0050] By inserting the swing rod 202h into the limiting groove X, the position of the fixing nut 201b can be limited to prevent the fixing nut 201b from loosening and causing the insert 103 to be unable to work stably.

[0051] Specifically, the limiting member 203 includes a limiting block 203a and a second spring 203b. The limiting block 203a slides in the fixed plug plate 201a, and an end of the second spring 203b is fixed to the inner wall of the limiting block 203a.

[0052] A slope is provided on one side of the limit block 203a. When the rocker arm 202h squeezes one side of the limit block 203a, the limit block 203a can move downward, so that the rocker arm 202h can move to just above the limit block 203a. At this time, under the action of the return elastic force of the second spring 203b, the limit block 203a will be clamped to the bottom of the rocker arm 202h, thereby limiting the rocker arm 202h.

[0053] During use, when the microwave level detection switch needs to be fixed, the mounting plate 202b can be fixed first, and then the threaded column 101 can be placed in the fixed plug plate 201a. At this time, the fixing nut 201b is rotated so that the fixing nut 201b and the plug body 103 squeeze the fixed plug plate 201a. At this time, the fixing column 201d is inserted into the fixing groove V on the surface of the fixing ring 201c, so as to limit the angle of the fixing ring 201c so that the fixing ring 201c will not rotate. At this time, the position of the fixed plug plate 201a can be moved so that the plug body 103 is in a suitable position, and then the swing rod 202h is moved so that the swing rod 202h drives the driving column 202d to rotate, so that the driving column 202d drives the cam Block 202e squeezes the insertion rod 202c, so that the insertion rod 202c is inserted into the slot W, thereby fixing the position of the fixed plug plate 201a. As the rocker arm 202h moves, the rocker arm 202h squeezes one side of the limit block 203a, which can make the limit block 203a move downward, so that the rocker arm 202h can move to the top of the limit block 203a. At this time, under the action of the reset elastic force of the second spring 203b, the limit block 203a will be snapped into the bottom of the rocker arm 202h, thereby limiting the rocker arm 202h. At this time, the rocker arm 202h is inserted into the limit groove X, which can limit the position of the fixing nut 201b, preventing the fixing nut 201b from loosening and causing the insert 103 to be unable to work stably.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
