[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0028] See also Figure 1-6 As shown, a technical solution provided by the utility model:
[0029] like Figure 1-3 As shown, the protective liquid level gauge device comprises two symmetrical angle steels, which are placed opposite to each other with a gap in between, and the upper and lower ends of the angle steels are provided with two connecting plates, the connecting plates are provided with through holes, and screws pass through the connecting plates corresponding to the two angle steels from the through holes, and the upper ends of the two angle steels are covered with a rear top cover 11 and a front top cover 12, and the lower ends of the two angle steels are covered with a rear bottom cover 13 and a front bottom cover 14;
[0030] The rear top cover 11 and the front top cover 12 are both trapezoidal, and the waist of the trapezoid is movably connected to the side cover 16 through a spring 17, the upper bottom edge is fixedly connected to the shielding component, and the center of the lower bottom edge is opened with a semicircular through hole 19;
[0031] The rear bottom cover 13 and the front bottom cover 14 are both trapezoidal, and the waist of the trapezoid is movably connected to the side cover 16 through the spring 17, the upper bottom edge is fixedly connected to the card slot 15, and the center of the lower bottom edge is opened with a semicircular through hole 19;
[0032] It should be noted that a liquid level gauge protection device is disclosed based on Chinese patent number CN201520968750, and gaps are left in the middle and at the top and bottom of the two symmetrical angle steels. The front top cover 12 and the rear top cover 11 of the device are respectively buckled on the upper end of the angle steel, and the front bottom cover 14 and the rear bottom cover 13 are respectively buckled on the lower end of the angle steel. When buckled, the front top cover 12 and the front bottom cover 14 are on the same side of the angle steel, and the rear top cover 11 and the rear bottom cover 13 are on the same side of the angle steel. Since a semicircular through hole 19 is opened at the center of the two top covers and the two bottom covers, the liquid level gauge can pass through the formed center through hole when buckled. At the same time, a shielding component is provided at the front end of the rear top cover 11 and the front top cover 12. After buckling, the shielding component can be used to protect the gap between the two angle steels.
[0033] like Figure 2-3 As shown, the diameter of the semicircular through hole 19 is larger than the diameter of the liquid level meter.
[0034] like Figure 1-3 As shown, the rear bottom cover 13 is arranged at the rear end of the bottom of the two angle steels, the front bottom cover 14 is arranged at the front end of the bottom of the two angle steels, the rear top cover 11 is arranged at the rear end of the top of the two angle steels, and the front top cover 12 is arranged at the front end of the top of the two angle steels.
[0035] like Figure 2-4 As shown, a groove is provided in the bottom of the side cover 16, an anti-slip layer is fixed on the inner surface of the groove, and the groove matches the bevel edge of the angle steel;
[0036] It should be noted that the groove of the side cover 16 can be just buckled on the bevel of the angle steel. Due to the anti-skid layer provided in the groove, the side cover 16 is not easy to slide off the angle steel after buckling.
[0037] like Figure 2-6 As shown, the shielding assembly includes a rotating wheel 1801, a roller 1802, a strip hole 1803, a shielding curtain 1804, and a box body 1805. The roller 1802 is rotatably arranged in the box body 1805, and the two ends of the roller 1802 are fixedly connected with the rotating wheel 1801. The shielding curtain 1804 is rolled up on the roller 1802. The box body 1805 is provided with a strip hole 1803 on the side away from the upper bottom edge. The extended end of the shielding curtain 1804 is fixed on the pull shaft 21, and the two sides of the pull shaft 21 are fixedly connected with spring buttons 20.
[0038] It should be noted that after the front top cover 12 and the rear top cover 11, the front bottom cover 14 and the rear bottom cover 13 are fixed in position respectively, pull the pull shaft 21 downward, and the shielding curtain 1804 will be pulled out from the box body 1805 through the bar hole 1803 under the action of the rotation of the roller 1802. After pulling the bottom cover into position, put the pull shaft 21 into the card slot 15, and the spring buttons 20 at both ends of the pull shaft 21 will pass through the through hole 1501 to fix the pull shaft 21. When the pull shaft 21 needs to be taken out, press the spring button 20 to release the fixation of the pull shaft 21 by the card slot 15. The shielding curtain 1804 is made of tough transparent material and can be retracted and extended at will without affecting normal data reading. The gap between the two angle steels can be protected by the shielding curtain 1804.
[0039] like Figure 2-6 As shown, the length of the pull shaft 21 is greater than the length of the bar hole 1803 and the card slot 15 .
[0040] like Figure 5 As shown, a card slot 15 is fixedly provided at the bottom edge of the bottom end cover, a through slot is provided in the card slot 15, and through holes 1501 are provided on the left and right sides of the through slot.
[0041] like Figure 5-6 As shown, the spring buttons 20 on both sides of the pull shaft 21 correspond one to one with the through holes 1501 on both sides of the slot 15 .
[0042] The protective liquid level gauge device provided by the utility model is based on a liquid level gauge protective device structure disclosed in Chinese Patent No. CN201520968750, and is a technical improvement for the problem of protection gaps in two angle steel protective liquid level gauges. The specific working principle is as follows:
[0043] When the utility model is in use, the two angle steels 1 are first fixedly connected by screws 3 and connecting plates 2, and then the side covers 16 of the front top cover 12 and the rear top cover 11 are set on the beveled edges of the angle steels. The left and right stretching distances of the side covers can be adjusted by springs 17. The front bottom cover 14 and the rear bottom cover 13 are set on the lower ends of the angle steels in the same way, and the shielding curtain 1804 at the front end of the front top cover 12 is pulled out from the strip holes 1803 through the pull shaft 21. After being pulled to a suitable position at the bottom of the angle steel, the pull shaft 21 is inserted into the card slot 15 at the front end of the front bottom cover 14, and the spring button 20 is used to engage with the through holes 1501 on both sides of the card slot 15. The pull shaft 21 can be removed by pressing the spring button 20. Similarly, the rear top cover 11 and the rear bottom cover 13 are shielded and protected by a shielding assembly. Since the shielding curtain 1804 is made of transparent and tough material, it does not affect the reading of the liquid level meter data. At the same time, the liquid level meter leaking out of the top and gaps of the two angle steels can be protected.
[0044] The above shows and describes the basic principle, main features and 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 preferred examples of the utility model and are not used to limit the utility model.
