Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a pressure sensor packaging structure. Background Art

[0002] A pressure sensor is a sensor that can detect pressure, so it is extremely sensitive to external forces. When storing the pressure sensor, it is necessary to avoid external force squeezing the pressure sensor. When the sensor is not used for a long time, it is also necessary to keep it away from light and dust. Therefore, the pressure sensor usually needs to be stored in a sealed environment.

[0003] When existing pressure sensors are sold or consigned, plastic foam and other materials are used for cushioning and shock absorption. However, these materials are usually disposable. When the pressure sensor is taken out for use, there is a lack of structure and container to package it again. Therefore, a packaging structure is needed to solve this problem. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pressure sensor packaging structure, which can repeatedly package the pressure sensor to facilitate subsequent storage, consignment, etc., so as to solve the problems raised in the above-mentioned background technology.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pressure sensor packaging structure of the utility model includes a pressure sensor 8 and a packaging shell, wherein the packaging shell is composed of two half shells, the two half shells are respectively sleeved on both sides of the pressure sensor 8, and the pressure sensor 8 is covered and arranged, and the half shells are composed of a cover body 1 and a half ring 2, the half ring 2 is arranged in the lower half of the cover body 1, the half shell is sleeved on the upper half of the pressure sensor 8, the half ring 2 is arranged on the outside of the pressure sensor 8, and the open end of the lower end of the half ring 2 is bent inwardly to form a sealing portion 9 of an arc structure, and the sealing portion 9 is arranged in contact with the outer ring surface of the pressure sensor 8;

[0023] A sealing plug can be inserted into the fixing hole of the pressure sensor to seal the fixing hole and prevent external dust from entering the packaging shell.

[0024] In this embodiment, an arc groove is provided at one end of the semi-ring 2, and the arc grooves are combined to form a wiring hole. A wiring tube 5 is installed at the pressure sensor 8 opposite to the wiring hole. The other end of the wiring tube 5 extends to the outside through the wiring hole. A wire 3 connected to the pressure sensor 8 is installed inside the wiring tube 5. A C-tube 6 is installed on the outside of the semi-ring 2 located on the arc groove. The C-tube 6 is sleeved on the outside of the wiring tube 5. Two C-tubes 6 are combined to form a round tube. The outer thread of the round tube is connected to a locking ring 7 that fixes the C-tube 6 and the semi-ring 2 together.

[0025] In this embodiment, a U-shaped groove is provided on the other side of the half ring 2, and the relative U-shaped grooves are combined to form a connecting port. A connecting seat 4 is installed opposite the connecting port of the pressure sensor 8, and the connecting seat 4 and the half ring 2 are fixedly connected by a torsion spring hinge.

[0026] In this embodiment, a plurality of positioning grooves are provided on the bottom surface of the cover body 1, and a positioning rod 10 is inserted into the positioning grooves. A compression spring is installed at one end of the positioning rod 10, and the other end of the compression spring is installed on the inner wall surface of the positioning groove. The other end of the positioning rod 10 is installed on the sealing part 9. The cover body can be positioned by the positioning rod so that the cover body can only move up and down along the positioning rod to avoid displacement.

[0027] In this embodiment, the outer ring surface of the cover body 1 is arranged in contact with the inner ring surface of the half ring 2 to ensure a sealing arrangement between the cover body and the half ring.

[0028] In this embodiment, the opposite surfaces of the cover body 1 and the opposite surfaces of the half ring 2 are both arranged to abut against each other, so that the half shells can fit tightly together to ensure a sealing effect.

[0029] In this embodiment, the bottom surface of the half ring 2 and the bottom surface of the sealing portion 9 are both flush with the bottom surface of the pressure sensor 8, so that the bottom surface of the pressure sensor can fully contact any plane, and the existence of the half shell does not affect the installation of the pressure sensor.

[0030] When in use, the locking ring is rotated to separate from the round tube and put on the wire, so that the locking ring is always on the wire to avoid loss;

[0031] After losing the obstruction of the locking ring, the half shell can be automatically opened outward by the torsion spring hinge. After the half shell is removed from the outside of the pressure sensor, the pressure sensor can be exposed, and the cover body can be pulled downward by the inward contraction of the compression spring, so that the cover body moves downward along the positioning column to lower the height of the half shell, so that the detection end surface on the pressure sensor can be higher than the top surface of the half shell, thereby ensuring that the pressure sensor can fully contact the object to be detected.

[0032] When not in use, the cover can be lifted upward so that it is higher than the top surface of the pressure sensor, and the half shell can be closed inward with the torsion spring hinge as the center, so as to encapsulate and protect the pressure sensor. The C-type tube can be put on the outside of the wiring tube, and the C-type plate can be fixed by a threaded locking ring, avoiding the opening of the half shell and increasing stability.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
