DETAILED DESCRIPTION

[0026] Since the existing glass tube level gauge in the prior art is installed sideways, the glass tube is easily exposed and broken, and the glass tube cannot be protected. Therefore, the inventor provides a level gauge with a protective structure to solve the above defects.

[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Please refer to Figures 1 to 6 The embodiment of the utility model provides a liquid level meter with a protective structure, including:

[0029] A connecting assembly 100, the connecting assembly 100 comprises a connecting valve head seat 110 and a sealing connecting pipe head 120 fixedly connected to the connecting valve head seat 110;

[0030] Liquid level tube 200, both ends of which are sealed and connected to the sealed connecting pipe head 120;

[0031] The protective cover 300 includes a cover shell 310 detachably connected to the connecting valve head seat 110 and a cleaning scraper 320 movably installed on the cover shell 310 so as to move up and down. The cleaning scraper 320 scrapes and cleans the surface of the liquid level tube 200.

[0032] The cover shell 310 is detachably installed on the connecting valve head seat 110, so that the cover shell 310 can protect the liquid level tube 200 connected between the connecting valve head seat 110. Compared with the traditional glass tube liquid level gauge, the liquid level gauge is designed with the cover shell 310, so that after the cover shell 310 is installed and connected with the connecting valve head seat 110, the liquid level tube 200 can be protected to prevent the liquid level tube 200 from being broken.
