Description

Technical Field

[0001] The utility model belongs to the technical field of membrane box sensors, and in particular relates to a miniaturized metal membrane box sensor with a sealing structure. Background Art

[0002] A diaphragm sensor is a sensor that uses a thin film deformation sensitive element to measure physical quantities such as pressure, temperature, liquid level, and displacement. Its main components include a diaphragm, a connecting tube, and a measuring circuit. The diaphragm is generally made of stainless steel, copper, alloy, and other materials, and can withstand high pressure and high temperature. The diaphragm sensor can be divided into a pressure sensor, a temperature sensor, a liquid level sensor, a displacement sensor, and the like. Publication number: CN210322158U discloses a gas pressure sensor with a packaged protection structure, including a sensor body and an anti-corrosion coating. A protective component is provided on one side of the sensor body, and an insulating pad is bonded and fixed to the middle of the inner wall of the sensor body. The anti-corrosion coating is brushed on the outside of the sensor body, and a sealing connection component is provided at the lower end of the sensor body. The gas pressure sensor with a packaging protection structure has a connecting spiral head that can be rotatably fixed to the inner side of the sensor body through an internal thread and an external thread until the protective pad on the outer side of the connecting spiral head contacts the left side of the sensor body and stops. Then, glue is injected into the space between the connecting spiral head and the sensor body through the protective pad opened inside the protective pad. This structure has high sealing performance, realizes packaging protection of the gas pressure sensor, prevents dust and water stains from entering the interior of the gas pressure sensor, and indirectly extends the service life of the gas pressure sensor.

[0003] However, there are some problems with the existing technology: a gap will appear at the connection between the adapter and the cable of the existing gas pressure sensor, so when the gas pressure sensor works outdoors and it rains outside, rainwater will enter the adapter along the cable and the surface of the adapter, causing a short circuit in the internal circuit of the sensor. Therefore, we propose a miniaturized metal diaphragm box sensor with a sealed structure. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a miniaturized metal diaphragm box sensor with a sealing structure, which can prevent rainwater from entering the adapter along the cable and the adapter surface through the first sealing gasket and the second sealing gasket, thereby achieving the advantage of protecting the internal circuit of the sensor body.

[0005] The utility model is implemented as follows: a miniaturized metal diaphragm box sensor with a sealing structure comprises a sensor body, a first sealing box and a second sealing box, a cable is arranged in the adapter of the sensor body, a first set hole is opened at one end of the first sealing box, a second set hole is opened at the other end of the first sealing box, a third set hole is opened at one end of the second sealing box, and a fourth set hole is opened at the other end of the second sealing box, a first sealing gasket is laid on the first sealing box, and the first sealing gasket is laid to the inner walls of the first set hole and the second set hole, a second sealing gasket is laid on the second sealing box, and the second sealing gasket is laid to the inner walls of the third set hole and the fourth set hole, connecting blocks are fixedly installed on both sides of the first sealing box, and mounting blocks are fixedly installed on both sides of the second sealing box, an insertion hole is opened on the mounting block, a buckle assembly is arranged at one end of the mounting block, the lower end of the connecting block is inserted through the insertion hole, and the buckle assembly is used to fix the connecting block in the insertion hole.

[0006] Optionally, the first sleeve hole and the third sleeve hole are sleeved together on the surface of the adapter, the second sleeve hole and the fourth sleeve hole are sleeved together on the surface of the cable, and the first sealing gasket and the second sealing gasket are fitted together.

[0007] Optionally, the caliber of the first set hole is greater than that of the second set hole, the caliber of the first set hole is the same as that of the third set hole, and the caliber of the second set hole is the same as that of the fourth set hole.

[0008] Optionally, an inclined surface is provided at the lower end of the connecting block, a through hole is provided at one end of the insertion hole, a buckle groove is provided at one end of the connecting block, and the buckle groove and the through hole correspond to each other.

[0009] Optionally, the buckle assembly includes a mounting frame, one end of which is fixedly mounted on one end of the mounting block.

[0011] Optionally, a connecting disk is fixed to one end of the buckle rod, and a return spring is elastically connected to one end of the connecting disk.

[0012] Optionally, one end of the return spring is fixedly mounted on one end of the sliding sleeve, and the other end of the buckle rod is inserted through the through hole into the buckle groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The staff brings the first sealing box and the second sealing box close to each other between the adapter and the cable, so that the first sealing pad and the second sealing pad are respectively sleeved on the surface of the adapter and the surface of the cable, and the connecting block is fixed in the insertion hole by the buckle assembly to avoid the first sealing box and the second sealing box from being separated, so that the first sealing pad and the second sealing pad can prevent rainwater from entering the adapter along the cable and the surface of the adapter, thereby achieving the effect of protecting the internal circuit of the sensor body.

[0015] 2. When the first sealing box and the second sealing box are brought closer to each other, the lower end of the connecting block is driven to be inserted into the insertion hole.
