Example

[0028] Reference Figure 1-Figure 6 , which is the first embodiment of the utility model, and this embodiment provides a high-temperature microwave level detection switch. The high-temperature microwave level detection switch includes a main body component 100 and a fixing component 200. The fixing component 200 can facilitate the installation and disassembly of the detection switch 103.

[0029] Specifically, the main component 100 includes a pipe 101, a mounting sleeve 102, a detection switch 103 and a mounting column 104. The mounting sleeve 102 is fixed on the pipe 101, the detection switch 103 is arranged on one side of the mounting sleeve 102, and one end of the mounting column 104 is fixed to the detection switch 103.

[0030] The pipeline 101 is used to transport liquid materials. There are two mounting sleeves 102, which are respectively fixed at the bottom and the top of the pipeline 101. The mounting sleeve 102 cooperates with the mounting column 104 to install and fix the detection switch 103. There are two detection switches 103, which are respectively fixed to the two mounting sleeves 102. The two detection switches 103 are used to detect the high and low positions of the liquid inside the pipeline 101 respectively. The detection switch 103 can withstand higher temperatures. This is the prior art and will not be elaborated in this solution.

[0031] Specifically, the fixing assembly 200 is disposed in the installation sleeve 102, and includes a positioning member 201, a locking member 202, a pushing member 203 and a sealing member 204.

No additional tools are required during the installation and disassembly process, thereby reducing the complexity and time and labor costs. The sealing member 204 is set, when the detection switch 103 is installed, the sealing between it and the installation sleeve 102 can be increased to avoid leakage of liquid materials during use. Example

[0033] Reference Figure 1-Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the positioning member 201 includes a positioning block 201 a, which is fixed in the mounting sleeve 102, a positioning groove 104 a is formed on the mounting column 104, the positioning block 201 a is engaged with the positioning groove 104 a, and a sliding groove 104 b is formed on the mounting column 104.

[0035] The positioning groove 104a is connected to the slide groove 104b. When installing the detection switch 103, the installation column 104 is inserted into the installation sleeve 102, and the positioning block 201a enters the slide groove 104b. When the installation column 104 moves a specified distance into the installation sleeve 102, the positioning block 201a will enter the positioning groove 104a. At this time, the detection switch 103 is rotated, and the positioning block 201a contacts the inner wall of the positioning groove 104a, thereby completing the preliminary fixation of the detection switch 103.

[0036] Specifically, the locking member 202 includes a limit block 202a, a chamber 201a-1 is defined in the positioning block 201a, the limit block 202a is located in the chamber 201a-1, a limit hole 104a-1 is defined on the inner wall of the positioning groove 104a, and the limit block 202a engages with the limit hole 104a-1.

[0037] When the positioning block 201a contacts the inner wall of the positioning groove 104a, the first spring 202b applies a thrust to the limit block 202a, so that the limit block 202a enters the limit hole 104a-1 and engages with the limit hole 104a-1. The positioning block 201a can be locked by the cooperation of the two, so that the positioning block 201a cannot move in the positioning groove 104a, thereby completing the installation and fixation of the detection switch 103.

[0038] Specifically, the locking member 202 further includes a first spring 202b, and two ends of the first spring 202b are respectively fixed to the limiting block 202a and the inner wall of the chamber 201a-1.

[0039] Specifically, the locking member 202 further includes a fixing block 202c and a fixing column 202d, one side of the fixing block 202c is fixed to the limiting block 202a, and one end of the fixing column 202d is fixed to the inner wall of the chamber 201a-1.

[0040] The fixing column 202d is movably connected to the fixing block 202c, and the two cooperate to position the limiting block 202a to prevent it from shifting during movement.

[0041] Specifically, the push member 203 includes a push rod 203a and a fixing plate 203b. The push rod 203a is inserted into the mounting sleeve 102. The fixing plate 203b is fixed to one end of the push rod 203a. The limit block 202a is provided with a force groove 202a-1 corresponding to the push rod 203a.

[0042] When the detection switch 103 needs to be disassembled, the fixing plate 203b is pressed to drive the push rod 203a to move, so that the push rod 203a squeezes the inner wall slope of the force groove 202a-1. Through the cooperation of the two, the limit block 202a can be driven to move downward, and the limit block 202a is separated from the limit hole 104a-1, thereby releasing the restriction on the positioning block 201a, and then the detection switch 103 is rotated in the reverse direction, so that the mounting column 104 drives the positioning block 201a to move in the reverse direction in the positioning groove 104a, and the positioning block 201a enters the slide groove 104b. At this time, the detection switch 103 can be pulled upward to complete the disassembly. Example

[0043] Reference Figure 1-Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0044] Specifically, the inner wall of the stress-bearing groove 202a-1 is inclined.

[0045] Specifically, the pusher 203 further includes a support block 203c and a second spring 203d. The support block 203c is fixed to one side of the push rod 203a. Both ends of the second spring 203d are respectively fixed to the support block 203c and the inner wall of the chamber 201a-1.

[0046] The second spring 203d applies a pulling force to the support block 203c, and the support block 203c drives the push rod 203a to move, so that the push rod 203a can be reset after moving.

[0047] Specifically, the sealing member 204 includes a fixing frame 204a, a sealing sleeve 204b and an extrusion strip 204c. The fixing frame 204a is fixed in the installation sleeve 102, the sealing sleeve 204b is fixed in the fixing frame 204a, and the extrusion strip 204c is located in the fixing frame 204a.

[0048] The extrusion strips 204c are arc-shaped, and there are four of them, which are evenly distributed in a ring shape in the fixed frame 204a. When the mounting column 104 rotates, the extrusion strips 204c will squeeze the sealing sleeve 204b and make the sealing sleeve 204b contact with the outer side of the mounting column 104, thereby increasing the sealing between the mounting column 104 and the mounting sleeve 102, thereby preventing the leakage of liquid materials.

[0049] Specifically, the sealing member 204 further includes a force-bearing block 204 d and an extrusion block 204 e . The force-bearing block 204 d is fixed to one side of the extrusion strip 204 c , and the extrusion block 204 e is fixed to the bottom end of the mounting column 104 .

[0050] The number of the force-bearing blocks 204d and the extrusion blocks 204e corresponds to the extrusion strip 204c. The extrusion blocks 204e and one side of the extrusion blocks 204e are both inclined, and the inclined surfaces of the two correspond to each other. When the mounting column 104 rotates, the extrusion block 204e will be driven to move toward the position of the force-bearing block 204d. When the positioning block 201a is about to contact the inner wall of the positioning groove 104a, the extrusion block 204e will contact the inclined surface of the force-bearing block 204d and squeeze it. Through the cooperation of the two, the extrusion strip 204c can be driven to move, so that the extrusion strip 204c can squeeze the sealing sleeve 204b.

[0051] During use, when installing the detection switch 103, insert the mounting column 104 into the mounting sleeve 102, and make the positioning block 201a enter the slide groove 104b. When the mounting column 104 moves a specified distance into the mounting sleeve 102, the positioning block 201a will enter the positioning groove 104a. At this time, rotate the detection switch 103 and make the positioning block 201a contact the inner wall of the positioning groove 104a, thereby completing the preliminary fixation of the detection switch 103.

[0052] At the same time, the first spring 202b applies a thrust to the limit block 202a, so that the limit block 202a enters the limit hole 104a-1 and engages with the limit hole 104a-1. Through the cooperation of the two, the positioning block 201a can be locked, so that the positioning block 201a cannot move in the positioning groove 104a, thereby completing the installation and fixation of the detection switch 103.

[0053] When the mounting column 104 rotates, it drives the extrusion block 204e to move toward the position of the force-bearing block 204d. When the positioning block 201a is about to contact the inner wall of the positioning groove 104a, the extrusion block 204e contacts the inclined surface of the force-bearing block 204d and squeezes it. The cooperation of the two can drive the extrusion bar 204c to move, so that the extrusion bar 204c squeezes the sealing sleeve 204b and makes the sealing sleeve 204b contact the outer side of the mounting column 104, thereby increasing the sealing between the mounting column 104 and the mounting sleeve 102, thereby preventing the leakage of liquid materials.

[0054] When the detection switch 103 needs to be disassembled, the fixed plate 203b is pressed to drive the push rod 203a to move, so that the push rod 203a squeezes the inner wall slope of the force groove 202a-1. Through the cooperation of the two, the limit block 202a can be driven to move downward, and the limit block 202a is separated from the limit hole 104a-1, thereby releasing the restriction on the positioning block 201a, and then the detection switch 103 is rotated in the reverse direction, so that the installation column 104 drives the positioning block 201a to move in the opposite direction in the positioning groove 104a, and the positioning block 201a enters the slide groove 104b. At this time, the detection switch 103 can be pulled upward to complete the disassembly, so that the detection switch 103 does not need to use additional tools during the installation and disassembly process, thereby reducing the tediousness and reducing time and labor costs.

[0055] 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.
