Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level sensors, and in particular relates to a protective liquid level sensor component. Background Art

[0002] The liquid level sensor is a pressure sensor that measures the liquid level. The liquid level sensor can be divided into contact type, such as float type liquid level transmitter, magnetic liquid level transmitter, and immersion type liquid level transmitter. The second type is non-contact type, which is divided into ultrasonic liquid level transmitter, radar liquid level transmitter, etc. The liquid level sensor uses the principle of fluid statics to measure the liquid level, which is an important application of pressure sensors. Since most of the existing liquid level sensors are not easy to carry, a protective liquid level sensor assembly is required.

[0003] According to the patent with publication number CN219434167U, a contact liquid level sensor is disclosed, including a contact liquid level sensor probe: one end of the contact liquid level sensor probe is fixedly connected to a probe wire, the outer circumferential wall of the probe wire is movably connected to a positioning sleeve, and the outer side of the positioning sleeve is provided with a movable sleeve, which relates to the field of liquid level sensors.

[0004] The above technical solution solves the problem that when the liquid level sensor is retracted from the sample, personnel who come into contact with the surface of the probe of the liquid level sensor will be contaminated with a small amount of weakly corrosive chemical solution of the sample, which may cause personal injury. However, when the staff use the liquid level sensor, it is often necessary to fix the probe and the electronic display. The exposed probe and electronic display are prone to bumps, which may affect the use of the liquid level sensor. We provide a protective liquid level sensor assembly to solve the above problem.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 6 As shown, an embodiment of the utility model provides a protective liquid level sensor assembly, specifically including a base plate 1, the upper surface of the base plate 1 is fixedly connected with a first limiting bin 2 and a second limiting bin 3, the upper surfaces of the first limiting bin 2 and the second limiting bin 3 are hinged with a first opening and closing plate 4 and a second opening and closing plate 5 through hinges, and the outer surfaces of the first opening and closing plate 4 and the second opening and closing plate 5 are provided with an arc groove adapted to the conduit 7, which is convenient for limiting the conduit 7 and preventing the probe body 9 and the electronic display body 10 from slipping out from the inside of the first limiting bin 2 and the second limiting bin 3.

The inner wall of the fixed bin 601 is slidably connected to the limit plate 603. The inner wall of the fixed bin 601 and the outer surface of the limit plate 603 should be set to be relatively smooth so that the limit plate 603 can slide on the inner wall of the fixed bin 601. The outer surface of the limiting plate 603 is slidably connected to the inner wall of the connecting chamber 602. The inner wall of the connecting chamber 602 is relatively smooth, so that the connecting chamber 602 can slide on the inner wall of the connecting chamber 602, which is convenient for limiting the first opening and closing plate 4 and the second opening and closing plate 5.

The end of the moving rod 607 close to the connecting bin 602 is fixedly connected with an arc-shaped extrusion block 606, and the outer surface of the arc-shaped extrusion block 606 is slidably connected to the inner wall of the limiting plate 603. The inner wall of the limiting plate 603 is provided with a limiting groove compatible with the arc-shaped extrusion block 606, so that the arc-shaped extrusion block 606 can limit the limiting plate 603 after sliding into the limiting groove. One end of the moving rod 607 away from the arc-shaped extrusion block 606 is fixedly connected to a moving plate 608.

A conduit 7 is provided on the outside of the winding rod 13, and a probe body 9 and an electronic display body 10 are installed at both ends of the conduit 7 respectively. The outer surface of the conduit 7 is in contact with the side of the first opening and closing plate 4 and the second opening and closing plate 5 that are close to each other.

[0035] The working principle and use method of the utility model are as follows: when the staff needs to carry the liquid level sensor for use, firstly, the catheter 7 is wound around the outer surface of the two winding rods 13, and after the catheter 7 is wound, the probe body 9 and the electronic display body 10 at both ends of the catheter 7 are respectively inserted into the corresponding first limit bin 2 and the second limit bin 3, and then the first opening and closing plate 4 and the second opening and closing plate 5 are closed. After the first opening and closing plate 4 and the second opening and closing plate 5 are closed, pushing the push plate 604 will drive the limit plate 603 to slide into the interior of the connecting bin 602. When the limit plate 603 moves to contact the arc extrusion block 606, an extrusion force is generated on the arc extrusion block 606, so that the arc extrusion block 606 and the moving rod 607 move toward the direction of the moving plate 608 and the second spring 609 is stretched by force. When the limit plate 603 moves to the point where the arc-shaped extrusion block 606 is flush with the groove on the inner wall of the limit plate 603, the stretched second spring 609 will immediately rebound and drive the moving rod 607 and the arc-shaped extrusion block 606 to move in the direction of the limit plate 603, so that the arc-shaped extrusion block 606 slides into the groove on the inner wall of the limit plate 603 to limit the limit plate 603, thereby achieving the effect of limiting the first opening and closing plate 4 and the second opening and closing plate 5, so that the probe body 9 and the electronic display body 10 are enclosed in the first limiting bin 2 and the second limiting bin 3 for protection, thereby avoiding collision between the probe body 9 and the electronic display body 10 during the carrying of the liquid level sensor, which affects the subsequent use of the liquid level sensor and facilitates the staff to carry it.
