Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a pressure sensor that is easy to disassemble. Background Art

[0002] A pressure sensor is a device that senses pressure and converts it into an electrical signal. The signal strength depends on the applied pressure. Pressure sensors usually consist of a pressure sensitive element and a signal processing unit. They can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors according to different test pressure types.

[0003] In order to protect the pressure sensitive elements of the pressure sensor from being damaged, a protective cover is generally provided on the top of the pressure sensor to provide protection. Currently available pressure sensors are capable of testing pressures under different conditions.

[0004] However, the protective cover and the main body of the currently available pressure sensors are mostly fixed with multiple screws. Although they can be fixed relatively stably, they are not convenient to disassemble when a fault occurs inside the pressure sensor. The staff needs to constantly remove the screws. When the maintenance is completed, they have to be reinstalled, which is time-consuming and labor-intensive. Disassembly and assembly are inconvenient and cannot meet maintenance needs. Therefore, a pressure sensor that is easy to disassemble is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pressure sensor that is easy to disassemble, which solves the problem that it is inconvenient to disassemble and requires workers to constantly remove screws. When the maintenance is completed, the screws have to be reassembled, which is time-consuming and labor-intensive. Disassembly and assembly are inconvenient and cannot meet maintenance needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a pressure sensor that is easy to disassemble, comprising a pressure sensor body, a protective cover, a base and a mounting seat, wherein a disassembly mechanism is provided on the outer surface of the pressure sensor body;

[0007] The disassembly and assembly mechanism includes mounting blocks fixedly connected to the left and right sides of the protective cover, a connecting plate hinged on the inner side of the mounting block, a fixing plate and a sleeve fixedly connected to the left and right sides of the pressure sensor body, plug holes are provided on the outer surfaces of the fixing plate and the connecting plate, an insertion rod is slidably connected to the inner side of the sleeve, assembly grooves are provided on the left and right sides of the top of the base, a screw rod is rotatably connected to the inner side of the assembly groove, a sliding block is threadedly sleeved on the outer surface of the screw rod, a plug plate is fixedly connected to the top of the sliding block, and slots are provided on the left and right sides of the pressure sensor body.

[0008] Furthermore, a transmission rod having one end penetrating through the base and extending to the outside is fixedly connected to the side surface of the screw rod, and a knob is fixedly connected to one end of the transmission rod away from the base.

[0009] Furthermore, a limiting rod is fixedly connected to the inner side of the assembly groove, and the sliding block is slidably connected to the limiting rod.

[0010] Furthermore, the plug rod is plugged and fixed to the plug hole, and the plug board is plugged and fixed to the slot.

[0011] Furthermore, a groove is provided in the middle of the top of the base and the mounting seat, and the base and the mounting seat are both made of stainless steel.

[0012] Furthermore, a damper for buffering and shock absorption is fixedly connected to the inner side of the mounting seat, and the front end of the damper is fixedly connected to the side surface of the base.

[0013] Furthermore, the outer diameters of the pressure sensor body and the protective cover are consistent, and mounting holes are provided around the bottom of the mounting seat.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The pressure sensor which is easy to disassemble is provided with a disassembly and assembly mechanism. When a fault occurs inside the pressure sensor body, the staff only needs to turn the knob to drive the screw to rotate synchronously with the cooperation of the transmission rod, so that the sliding block moves away from the pressure sensor body, thereby releasing the plug-in fixation between the plug plate and the slot. At this time, the staff can remove the pressure sensor body from the top of the base. Then, the staff only needs to pull the plug rod outward to make it slide inside the sleeve, thereby releasing the plug-in fixation between the plug rod and the socket. At this time, the staff can remove the protective cover from the top of the pressure sensor body for maintenance. Compared with the existing pressure sensor, the staff does not need to constantly remove the screws to remove the pressure sensor body and the protective cover. The disassembly and assembly is more convenient and more conducive to maintenance.

[0016] 2. The easily disassembled pressure sensor can stably fix the base into the groove of the mounting seat through the cooperation of the mounting seat and the damper, so that the damper can play a buffering and shock-absorbing effect, thereby improving the stability of the pressure sensor body and reducing its shaking frequency.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-4 In this embodiment, a pressure sensor that is easy to disassemble includes a pressure sensor body 1, a protective cover 2, a base 3 and a mounting seat 4. The outer surface of the pressure sensor body 1 is provided with a disassembly mechanism;

[0024] The disassembly and assembly mechanism includes a mounting block 5 fixedly connected to the left and right sides of the protective cover 2, a connecting plate 6 is hinged on the inner side of the mounting block 5, a fixing plate 7 and a sleeve 8 are fixedly connected to the left and right sides of the pressure sensor body 1, and the outer surfaces of the fixing plate 7 and the connecting plate 6 are provided with a plug hole 9, and the inner side of the sleeve 8 is slidably connected with a plug rod 10, and the left and right sides of the top of the base 3 are provided with a mounting groove 11, and the inner side of the mounting groove 11 is rotatably connected with a screw rod 12, and the outer surface of the screw rod 12 is threadedly sleeved with a sliding block 13, and the top of the sliding block 13 is fixedly connected with a plug plate 14, and the left and right sides of the pressure sensor body 1 are provided with a slot 15. When a fault occurs inside the pressure sensor body 1, the staff only needs to turn the knob 17 to drive the screw rod 12 to rotate synchronously with the cooperation of the transmission rod 16, so that the sliding block 13 is away from the pressure sensor body 1, thereby releasing the plug-in fixation of the plug plate 14 and the slot 15. At this time, the staff can remove the pressure sensor body 1 from the top of the base 3.

[0025] Then, the staff only needs to pull the plug rod 10 outward to make it slide inside the sleeve 8, thereby releasing the plug-in fixation between the plug rod 10 and the socket 9. At this time, the staff can remove the protective cover 2 from the top of the pressure sensor body 1 for maintenance. Compared with the existing pressure sensor, the staff does not need to constantly remove the screws to remove the pressure sensor body 1 and the protective cover 2, which makes disassembly and assembly more convenient and more conducive to maintenance.

[0026] A transmission rod 16 having one end penetrating through the base 3 and extending to the outside is fixedly connected to the side of the screw rod 12 , and a knob 17 is fixedly connected to one end of the transmission rod 16 away from the base 3 .

[0027] It should be noted that the inner side of the assembly groove 11 is fixedly connected with a limit rod 18, and the sliding block 13 is slidably connected to the limit rod 18. By setting the limit rod 18, a limiting effect is achieved, thereby improving the stability of the sliding block 13 during movement, and the insertion rod 10 is plugged and fixed to the socket 9, and the insertion plate 14 is plugged and fixed to the slot 15.

[0028] At the same time, grooves are provided in the middle of the top of the base 3 and the mounting seat 4, and the base 3 and the mounting seat 4 are both made of stainless steel.

[0029] It should be understood that a damper 19 for buffering and shock absorption is fixedly connected to the inner side of the mounting seat 4, and the front end of the damper 19 is fixedly connected to the side of the base 3. Through the cooperation of the mounting seat 4 and the damper 19, the base 3 can be relatively stably fixed to the groove of the mounting seat 4, so that the damper 19 can play a buffering and shock absorption effect, thereby improving the stability of the pressure sensor body 1 and reducing its shaking frequency.

[0030] In addition, the outer diameters of the pressure sensor body 1 and the protective cover 2 are consistent, and mounting holes 20 are provided around the bottom of the mounting seat 4 .

[0031] The working principle of the above embodiment is:

[0032] When a fault occurs inside the pressure sensor body 1, the staff only needs to turn the knob 17, and with the cooperation of the transmission rod 16, the screw rod 12 can be driven to rotate synchronously, so that the sliding block 13 is away from the pressure sensor body 1, thereby releasing the plug-in fixation of the plug-in plate 14 and the slot 15. At this time, the staff can remove the pressure sensor body 1 from the top of the base 3, and then the staff only needs to pull the plug rod 10 outward to make it slide inside the sleeve 8, thereby releasing the plug-in fixation of the plug rod 10 and the socket 9. At this time, the staff can remove the protective cover 2 from the top of the pressure sensor body 1 for maintenance. Among them, when the maintenance is completed, the staff first needs to push the plug rod 10 inward so that the plug rod 10 is inserted into the socket 9, thereby fixing the protective cover 2, and then placing the pressure sensor body 1 into the groove of the base 3. After placement, turn the knob 17 in the opposite direction so that the sliding block 13 is close to the pressure sensor body 1, thereby driving the plug-in plate 14 to be inserted into the inside of the slot 15, and then plugging and fixing it to complete the installation.
