Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure sensor technology, specifically a pressure sensor for weighing polycarboxylate superplasticizer. Background Technology
[0002] A weighing pressure sensor is an instrument based on a pressure-sensitive element, used to determine the actual pressure applied to the sensor and convert this pressure information into an output signal, usually an electrical signal, for easy subsequent processing and recording. In the processing and production of polycarboxylate superplasticizers, a weighing pressure sensor is required to weigh the superplasticizer.
[0003] In existing technologies, pressure sensors require mounting devices, which are usually integrated with the pressure sensor. This makes the installation and removal process of pressure sensors quite complex, often requiring the removal of the pressure sensor along with its mounting device. This is not only time-consuming and labor-intensive, but also prone to causing disassembly difficulties. In addition, pressure sensors lack effective protection measures during use and are easily damaged by external factors, such as physical impacts. This not only shortens the lifespan of the sensor, but also increases the cost of maintenance and replacement.
[0004] Therefore, a pressure sensor for weighing polycarboxylate superplasticizer is needed to solve the problems of existing technologies where the pressure sensor is integrated with the fixing device, making installation and disassembly difficult, and the sensor is easily damaged by external factors during use. Utility Model Content
[0005] The purpose of this invention is to provide a pressure sensor for weighing polycarboxylate superplasticizer, in order to solve the problems in the prior art where the pressure sensor is integrated with the fixing device, resulting in difficulties in installation and disassembly, and is easily damaged by external factors during use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure sensor for weighing polycarboxylate superplasticizer, comprising a sensor body and a mounting plate, wherein two sets of symmetrically distributed fixing mechanisms are provided on the top surface of the mounting plate, and a protective component is provided on the outer surface of the sensor body;
[0007] Each set of fixing mechanisms includes two parallel sliding rods, which are respectively fixedly connected to one side of the top surface of the mounting plate. The same moving plate is slidably sleeved on the outer surface of the two sliding rods. A limit block is coaxially fixedly connected to the top of the sliding rod. A spring is sleeved on the outer surface of the sliding rod. Two parallel insertion holes are opened through the top surface of the moving plate. A pull rod is fixedly connected to the top surface of the moving plate. An anti-slip pad is fixedly connected to the bottom surface of the moving plate.
[0008] It should be noted in the solution that the protective component includes a protective shell one and a protective shell two. The outer walls on both sides of the protective shell one are rotatably connected with buckles, and the outer walls on both sides of the protective shell two are fixedly connected with mating parts that cooperate with the buckles.
[0009] It is worth noting that positioning plates are fixedly connected to the bottom of the front outer wall of the first protective shell and the bottom of the rear outer wall of the second protective shell. Two parallel rods that are adapted to the insertion holes are fixedly connected to the top surface of the two positioning plates.
[0010] Furthermore, it should be noted that the top surface of the mounting plate is provided with a positioning groove, and both outer walls of the mounting plate are fixedly connected with fixing plates, and the top surfaces of the two fixing plates are threaded with bolts.
[0011] In a preferred embodiment, the bottom and top ends of each spring are fixedly connected to the top surface of the corresponding movable plate and the bottom surface of the corresponding limiting block, respectively, and each insert rod is inserted into the corresponding insertion hole.
[0012] In a preferred embodiment, both the first protective shell and the second protective shell are mounted on the outer surface of the sensor body by means of snap-fit and mating parts, and the bottoms of the first protective shell, the second protective shell, and the two positioning plates are all inserted into the positioning groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Through the action of the fixing mechanism, the pull rod is pulled to move the moving plate, and the moving plate moves the insertion hole. With the cooperation of the insertion hole and the insertion rod, it is easy to install and disassemble the sensor body together with the first protective shell, the second protective shell, and the two positioning plates. The operation is simple and does not require the pressure sensor to be removed together with the fixing device, saving time and effort. It effectively avoids the problem of difficult installation and disassembly caused by the pressure sensor being connected to the fixing device as a whole.
[0015] 2. By using protective shell one and protective shell two, the sensor body is protected without hindering its connection to external devices, thus extending the service life of the sensor body and effectively avoiding the problem of pressure sensors being easily damaged by external factors during use.

[0021] 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.
[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a sensor body 1 and a mounting plate 2. The top surface of the mounting plate 2 is provided with two sets of symmetrically distributed fixing mechanisms 3, and the outer surface of the sensor body 1 is provided with a protective component 4.
[0023] Each set of fixing mechanisms 3 includes two parallel sliding rods 31. The two sliding rods 31 are fixedly connected to one side of the top surface of the mounting plate 2. The same moving plate 32 is slidably sleeved on the outer surface of the two sliding rods 31. A limit block 33 is coaxially fixedly connected to the top of the sliding rods 31. A spring 34 is sleeved on the outer surface of the sliding rods 31. Two parallel insertion holes 35 are opened through the top surface of the moving plate 32. A pull rod 36 is fixedly connected to the top surface of the moving plate 32. An anti-slip pad 37 is fixedly connected to the bottom surface of the moving plate 32.
[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the protective component 4 includes a first protective shell 41 and a second protective shell 42. The outer walls on both sides of the first protective shell 41 are rotatably connected with buckles 43, and the outer walls on both sides of the second protective shell 42 are fixedly connected with mating parts 44 that cooperate with the buckles 43.
[0025] Further as Figure 3 and Figure 4As shown, it is worth noting that positioning plates 5 are fixedly connected to the bottom of the front outer wall of protective shell 1 41 and the bottom of the rear outer wall of protective shell 2 42. Two parallel rods 6 that are adapted to the insertion holes 35 are fixedly connected to the top surface of the two positioning plates 5.
[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that the top surface of the mounting plate 2 is provided with a positioning groove 7, and both outer walls of the mounting plate 2 are fixedly connected with fixing plates 8, and the top surfaces of the two fixing plates 8 are threaded with bolts 9.
[0027] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom and top ends of each spring 34 are fixedly connected to the top surface of the corresponding moving plate 32 and the bottom surface of the corresponding limiting block 33, respectively. The elasticity of the spring 34 improves the stability of the moving plate 32 when it is connected to the plug rod 6 through the insertion hole 35. At the same time, it facilitates the movement of the moving plate 32 by pulling the pull rod 36, which facilitates the disassembly of the sensor body 1. Each plug rod 6 is inserted into the corresponding insertion hole 35. Through the cooperation of the insertion hole 35 and the plug rod 6, the sensor body 1 can be quickly installed and disassembled.
[0028] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that both the first protective shell 41 and the second protective shell 42 are installed on the outer surface of the sensor body 1 through the cooperation of the buckle 43 and the mating part 44. The first protective shell 41 and the second protective shell 42 protect the sensor body 1, preventing damage to the sensor body 1 from external factors during use and extending the service life of the sensor body 1. The bottoms of the first protective shell 41, the second protective shell 42 and the two positioning plates 5 are all inserted into the positioning groove 7. The positioning groove 7 facilitates quick positioning when installing the sensor body 1.
[0029] In summary: During installation, the pressure sensor is first mounted on the mounting plate 2 using two fixing plates 8 and two bolts 9. Then, the operator simultaneously pulls the two levers 36 upwards, causing the moving plate 32 to slide upwards on the outer surface of the corresponding sliding rod 31. As the moving plate 32 moves, it compresses the spring 34, causing the spring 34 to contract. At this point, the sensor body 1, along with the first protective shell 41, the second protective shell 42, and the two positioning plates 5, are all inserted into the positioning groove 7. After releasing the two levers 36, the elasticity of the spring 34 pushes the moving plate 32 downwards to reset, thus allowing the moving plate 32 to move downwards. The insertion hole 35 on plate 32 is inserted into the corresponding insertion rod 6 to lock and limit the positioning plate 5, thus completing the installation of the sensor body 1. At the same time, the bottom surface of the anti-slip pad 37 contacts the top surface of the positioning plate 5 to improve the stability of the sensor body 1 after installation. Conversely, the sensor body 1, together with the first protective shell 41, the second protective shell 42, and the two positioning plates 5, can be removed from the mounting plate 2. The operation is simple and does not require the pressure sensor to be removed together with the fixing device, saving time and effort. It effectively avoids the problem of difficult installation and disassembly caused by the pressure sensor being connected to the fixing device as a whole.
[0030] After removing the sensor body 1, along with protective shell 1 41, protective shell 2 42, and two positioning plates 5 from the mounting plate 2, rotate the two clips 43 to separate them from the corresponding mating parts 44, thus releasing the fixed connection between protective shell 1 41 and protective shell 2 42. After removing protective shell 1 41 and protective shell 2 42 from the outer surface of the sensor body 1, the sensor body 1 can be repaired or replaced. Conversely, the sensor body 1 can be quickly installed inside the protective shell 1 41 and protective shell 2 42. The protective shell 1 41 and protective shell 2 42 protect the sensor body 1 without hindering its connection to external equipment, extending the service life of the sensor body 1 and effectively preventing the pressure sensor from being easily damaged by external factors during use.
