[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1 to 4 A level switch for a marine cylinder oil heating cabinet includes a level switch body 1 and an installation assembly 2 disposed outside the level switch body 1 for connecting to the heating cabinet. The installation assembly 2 is provided with a lifting assembly 3 for detecting the level switch body 1.

[0026] The lifting assembly 3 includes two pull rods 301. The bottom ends of the two pull rods 301 are fixedly connected to the connecting brackets 302. A U-shaped lever 303 is fixedly connected to one side of the connecting brackets 302. A locking block 304 is slidably sleeved on the outside of the pull rods 301. An upper spring seat 305 is provided at the bottom of the locking block 304. A lower spring seat 306 is fixedly sleeved on the pull rods 301. The same spring 307 is provided between the upper spring seat 305 and the lower spring seat 306. The spring 307 is fixed between the upper spring seat 305 and the lower spring seat 306 and can play a certain supporting role. A handle 308 is provided at the top of the pull rods 301.

[0027] When the operator holds the handle 308 and pulls the pull rod 301 upward, the connecting bracket 302 at the bottom can drive the U-shaped lever 303 to move upward, so that the U-shaped lever 303 can abut against the float 103 and move it upward. When the position of the float 103 changes, the working status of the liquid level switch body 1 can be used to detect whether the detector is normal. After the test is completed, simply release the hand, and the U-shaped lever 303 can quickly reset under the elastic force of the spring 307, which is convenient for testing the liquid level switch body 1 without disassembly.

[0028] The liquid level switch body 1 includes a controller 101, a rod 102 is provided on the controller 101, two floats 103 are provided on the rod 102, and a flange 104 is fixedly sleeved on the rod 102.

[0029] Mounting assembly 2 includes mounting plate 201, which has multiple mounting holes 202 and two fixing holes 203. A sealing gasket 204 is provided at the bottom of mounting plate 201.

[0030] The mounting hole 202 allows the mounting plate 201 to be easily fastened to the heating cabinet, while the fixing hole 203 allows the lifting component 3 to be easily installed.

[0031] The top of the card block 304 is provided with an external threaded fixing cylinder 4, which slides through the corresponding fixing hole 203, and a threaded cap 5 is threaded on the external threaded fixing cylinder 4.

[0032] The external threaded fixing sleeve 4 and threaded cap 5 are used together to connect the locking block 304 to the mounting plate 201. The installation method is simple and convenient for subsequent maintenance.

[0033] Example 2:

[0034] Please see Figures 1 to 4 This embodiment provides a technical solution based on embodiment one: two anti-deviation cylinders 6 are provided on the mounting plate 201, and a side plate 7 is provided on one side of each of the two lower spring seats 306. An anti-deviation rod 8 is fixedly connected to the top of each of the two side plates 7, and the top of each of the two anti-deviation rods 8 slides into the corresponding anti-deviation cylinder 6.

[0035] The anti-deviation cylinder 6, side plate 7 and anti-deviation rod 8, when used together, make the pull rod 301 more stable during the lifting and lowering process and prevent deviation. This allows the U-shaped lever 303 to make more even contact with the float 103, making the lifting and lowering of the float 103 more stable and convenient for testing.

[0036] Multiple fastening bolts 9 are fixedly connected to the top of the mounting plate 201. The fastening bolts 9 slide through the flange 104, and locking nuts 10 are threaded on the fastening bolts 9.

[0037] The mounting plate 201 can be connected to the flange 104 by using the fastening bolts 9 and locking nuts 10 together;

[0038] A screw hole 11 is provided on the pull rod 301, and a limit plug 12 is threadedly connected to the screw hole 11;

[0039] The pull rod 301 can be limited by the screw hole 11 and the limiting screw plug 12 to prevent it from falling down under its own weight, making its operation more stable.

[0040] The top of the card block 304 is provided with multiple positioning slots 13, and the bottom of the mounting plate 201 is fixedly connected with multiple positioning rods 14, the bottom end of the positioning rods 14 slidingly extending into the corresponding positioning slots 13.

[0041] The positioning groove 13 and positioning rod 14 work together to facilitate the positioning and connection of the locking block 304 with the mounting plate 201, while improving the structural strength.
