Description

Technical Field

[0001] This utility model relates to the field of fixed structure technology, specifically to a liquid level sensor fixing structure. Background Technology

[0002] Currently, liquid level sensors are generally installed in sewage tanks to detect the water level information of sewage, so as to facilitate the adjustment of the drainage speed of the water pump.

[0003] Traditional liquid level sensors consist of a substrate and multiple liquid level rods of varying lengths, each used to detect different water levels. However, because the liquid level rods are generally quite long, they are easily bent by water flow during use, causing them to change position and resulting in decreased measurement accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a liquid level sensor fixing structure that can further fix the liquid level rod.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liquid level sensor fixing structure, comprising a substrate and multiple liquid level rods, and a fixing plate, wherein the fixing plate is disposed below the substrate and connected to the substrate, and the fixing plate has multiple limiting holes, wherein the multiple limiting holes are respectively configured to correspond to the multiple liquid level rods, and the limiting holes are adapted to the liquid level rods.

[0006] Furthermore, it also includes two lifting mechanisms, which are respectively disposed at both ends of the base plate;

[0007] The lifting mechanism includes a guide rail, a slider, and a locking assembly. The guide rail is fixedly mounted on the base plate along the longitudinal direction. The slider is disposed on the guide rail and slidably connected to the guide rail. The slider is fixedly connected to the fixed plate. The locking assembly is used to lock the slider at different positions on the guide rail.

[0008] Furthermore, the locking assembly includes a locking block, a guide rod, a spring, and locking teeth. The locking block is fixedly mounted on the slider, and the outer side of the locking block has multiple slots. The guide rod is arranged laterally and slidably connected to the base plate. The spring causes the guide rod to tend to move closer to the slider. The locking teeth are fixedly mounted on the guide rod and are adapted to the slots.

[0009] Furthermore, the bottom of the slot has a downwardly inclined and outwardly extending guide surface.

[0010] Furthermore, it also includes a positioning rod, the first end of which is fixedly connected to the fixing plate, and the second end of which extends vertically upward through the substrate and outward.

[0011] Furthermore, the cross-section of the guide rail is T-shaped.

[0012] The beneficial effects of this utility model are as follows: The liquid level sensor fixing structure provided by this utility model has a primary fixing effect on the liquid level rod by the base plate; the limiting holes on the fixing plate can limit the shaking of the liquid level rod, and the limiting holes provide a secondary fixing effect on the liquid level rod. This results in higher stability of the liquid level rod during use, making it less prone to bending and changing position due to water flow, and thus improving measurement accuracy.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] In this application, unless otherwise expressly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] In the description of this application, it should be understood that the terms "longitudinal", "horizontal", "level", "top", "bottom", "upper", "lower", "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0021] like Figures 1-3 As shown, this utility model provides a liquid level sensor fixing structure, including a base plate 10 and multiple liquid level rods 11. The above are all prior art, and the specific structure will not be described in detail here. This utility model also includes a fixing plate 20.

[0022] The fixing plate 20 is disposed below the substrate 10 and connected to the substrate 10. The fixing plate 20 has multiple longitudinally penetrating limiting holes 21, and the multiple limiting holes 21 are respectively provided with multiple liquid level rods 11. The limiting holes 21 are adapted to the liquid level rods 11.

[0023] During use, the liquid level rod 11 passes through the corresponding limiting hole 21. At this time, the base plate 10 plays a primary role in fixing the liquid level rod 11; the limiting hole 21 on the fixing plate 20 can limit the shaking of the liquid level rod 11, and the limiting hole 21 plays a secondary role in fixing the liquid level rod 11.

[0024] In this invention, the base plate 10 and the fixing plate 20 fix two points of the liquid level rod 11 respectively, so that the liquid level rod 11 is more stable during use, is less likely to be bent by the water flow and change position, and has higher measurement accuracy.

[0025] In one embodiment, two lifting mechanisms 30 are also included, which are respectively disposed at both ends of the substrate 10.

[0026] The lifting mechanism 30 includes a guide rail 31, a slider 32, and a locking assembly 40. The guide rail 31 is fixedly mounted longitudinally on the base plate 10. The slider 32 is disposed on the guide rail 31 and slidably connected to the guide rail 31, and the slider 32 is fixedly connected to the fixing plate 20. The locking assembly 40 is used to lock the slider 32 at different positions on the guide rail 31.

[0027] During use, the operator can open the locking component 40 according to the actual situation, and then move the fixing plate 20 up and down. When the fixing plate 20 moves to the appropriate position, the locking component 40 locks the slider 32 onto the guide rail 31, and the fixing plate 20 is also fixed. This design allows the distance between the fixing plate 20 and the base plate 10 to be adjusted according to the actual situation, thereby adjusting the secondary fixing effect of the fixing plate 20 on the liquid level rod 11.

[0028] In one embodiment, the locking assembly 40 includes a locking block 41, a guide rod 42, a spring 43, and locking teeth 44. The locking block 41 is fixedly mounted on the slider 32. Multiple inwardly extending slots 45 are formed on the outer surface of the locking block 41. The guide rod 42 is arranged laterally and slidably connected to a protrusion on the base plate 10. The spring 43 is sleeved on the rod, and its two ends are fixedly connected to the locking teeth 44 and the protrusion, respectively. The spring 43 causes the guide rod 42 to tend to move closer to the slider 32. The locking teeth 44 are fixedly mounted on the guide rod 42 and conform to the locking slots 45.

[0029] In the initial state, the locking tooth 44 is inserted into one of the slots 45. At this time, without the action of external force, the locking block 41 and the slider 32 are fixed on the guide rail 31 and cannot move up or down.

[0030] When the operator needs to move the fixed plate 20 up or down, first pull the guide rod 42 outward until the locking teeth 44 leave the corresponding slots 45. Then, after moving the fixed plate 20 up or down to the appropriate position, release the guide rod 42. Under the action of the spring 43, the locking teeth 44 will be reinserted into the corresponding slots 45. It is simple to operate and convenient to use.

[0031] In one embodiment, the bottom of the slot 45 has a downwardly inclined and outwardly extending guide surface 46.

[0032] When the operator needs to move the fixed plate 20 upwards, they can simply push it upwards. Under the action of the guide surface 46, the locking block 41 will automatically move outwards and leave the corresponding slot 45, then slip on the locking block 41. Once the fixed plate 20 has moved to the appropriate position, the guide rod 42 is released, and under the action of the spring 43, the locking tooth 44 will automatically re-insert into the corresponding slot 45.

[0033] This design eliminates the need for workers to manually pull the guide rod 42 outward when the fixed plate 20 needs to be moved upward, further simplifying the operation.

[0034] In one embodiment, a positioning rod 50 is also included. The first end of the positioning rod 50 is fixedly connected to the fixing plate 20, and the second end of the positioning rod 50 extends vertically upward through the positioning hole 12 on the substrate 10 and then extends outward.

[0035] The positioning rod 50 serves as a pre-positioning mechanism. When the positioning rod 50 is inserted into the positioning hole 12, the slider 32 and the guide rail 31 will automatically align. At this point, the operator can simply push the fixing plate 20 upwards, and the slider 32 and the guide rail 31 will slide together.

[0036] In one embodiment, the guide rail 31 has a T-shaped cross-section, and the slider 32 also has a corresponding T-shaped groove.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
