Description

Technical Field

[0001] The utility model relates to the technical field of double-check sensors, in particular to a double-check sensor with a protection frame. Background Art

[0002] Verification sensors are sensors used to detect and confirm that certain conditions, events, or parameters are as expected. They are typically designed for use in specialized environments or mission-critical applications where additional security verification and validation are required. These sensors are designed to ensure data integrity and reliability and prevent unauthorized access or tampering.

[0003] The shell of an existing double-check sensor generally includes a bottom shell and a top shell. A snap-fit ​​component is usually designed between the bottom shell and the top shell, so that the bottom shell and the top shell are connected by snap-fit. However, the snap-fit ​​connection makes the bottom shell and the top shell easier to disassemble, which is not conducive to protecting the internal components of the shell. The shell of the existing double-check sensor is connected by the bottom shell and the top shell, so that the overall structure of the shell is fixed. After the connection, the supporting strength of the shell is low, and the protection performance of the sensor components is poor. For this reason, we propose a double-check sensor with a protective frame. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The utility model provides a technical solution: a review sensor with a protective frame, comprising a lower connecting shell 1, the top of the lower connecting shell 1 is connected to an upper connecting shell 2, the inner wall of the lower connecting shell 1 is fixedly connected to a U-shaped fixing bracket 5, a positioning groove 10 is formed between the top of the U-shaped fixing bracket 5 and the inner wall of the lower connecting shell 1, and the top of the inner wall of the upper connecting shell 2 is fixedly connected to an L-shaped fixing plate 3.

[0024] It should be noted that after the U-shaped fixing frame 5 and the lower connecting shell 1 are fixedly connected, the stability of the lower shell is enhanced. After an L-shaped fixing plate 3 is fixedly connected to the top of the inner wall of the upper connecting shell 2, the stability of the upper shell is enhanced, so that the overall shell stability after the lower connecting shell 1 and the upper connecting shell 2 are connected is better, and the overall frame after connection forms a protective frame for the verification sensor.

[0025] The bottom end of the inner wall of the lower connecting shell 1 is fixedly connected with an elastic connecting plate 6, and the end of the elastic connecting plate 6 is integrally provided with a hook plate. The bottom end of the L-shaped fixing plate 3 is provided with a connecting groove 7, and the elastic connecting plate 6 is snapped into the connecting groove 7. A step 11 is formed at the connection between the L-shaped fixing plate 3 and the upper connecting shell 2, and the step 11 is slidably connected in the positioning groove 10.

[0026] It should be noted that when the utility model connects the upper connecting shell 2 and the lower connecting shell 1, the steps 11 at the two ends of the top of the upper connecting shell 2 are first correspondingly inserted into the positioning grooves 10 at the two ends of the top of the lower connecting shell 1, and the upper connecting shell 2 is pushed to slide on the lower connecting shell 1. During the connection process, the connecting rod 9 on the upper connecting shell 2 is correspondingly inserted into the connecting hole 8 on the lower connecting shell 1, and at the same time, the elastic connecting plate 6 on the inner wall of the lower connecting shell 1 is inserted into the connecting groove 7 on the L-shaped fixing plate 3. When the upper connecting shell 2 and the lower connecting shell 1 are fully connected, the hook plate at the end of the elastic connecting plate 6 is inserted into the inside of the connecting groove 7, so that the upper connecting shell 2 and the lower connecting shell 1 are tightly connected. After the lower connecting shell 1 and the upper connecting shell 2 are connected, the cooperation of the lower connecting shell 1, the upper connecting shell 2, the U-shaped fixing frame 5, the L-shaped fixing plate 3, and the fixing rod 12 forms a protective frame, which can better protect the internal sensor components.

[0027] Three connecting holes 8 are equidistantly formed at the end of the lower connecting shell 1 , and three connecting rods 9 are equidistantly fixedly connected to the bottom end of the upper connecting shell 2 , and the connecting rods 9 are clamped in the connecting holes 8 .

[0028] It should be noted that when the upper connecting shell 2 and the lower connecting shell 1 are connected, the steps 11 at both ends of the top of the upper connecting shell 2 are correspondingly inserted into the positioning grooves 10 at both ends of the top of the lower connecting shell 1. When the upper connecting shell 2 and the lower connecting shell 1 are connected, the connecting rod 9 on the upper connecting shell 2 can be inserted into the connecting hole 8 on the lower connecting shell 1. The connection between the connecting rod 9 and the connecting hole 8 can make the overall stability of the upper connecting shell 2 and the lower connecting shell 1 stronger after connection.

[0029] The bottom ends of the upper connecting shell 2 are equidistantly and integrally connected with fixing rods 12 , and the side walls of the lower connecting shell 1 are fitted and connected between the fixing rods 12 and the L-end side walls of the L-shaped fixing plate 3 .

[0030] It should be noted that after the upper connecting shell 2 and the lower connecting shell 1 are connected, the fixing rods 12 on both sides of the upper connecting shell 2 are connected to the top of the protruding plate 13, so that the side wall of the double-check sensor includes a row of fixing rods 12, a layer of lower connecting shell 1 side wall and a layer of U-shaped fixing frame side wall, thereby enhancing the stability of the protective frame.

[0031] The bottom ends of the corresponding two side walls of the lower connecting shell 1 are integrally connected with a protruding plate 13 , and the bottom of the fixing rod 12 is slidably connected to the top of the protruding plate 13 .

[0032] It should be noted that, after the lower connecting shell 1 and the upper connecting shell 2 are connected, the bottom of the fixing rod 12 is just located at the top of the protruding plate 13. When the upper connecting shell 2 is slidably connected on the lower connecting shell 1, the bottom of the fixing rod 12 is slidably connected to the top of the protruding plate 13, thereby ensuring a quick connection between the upper connecting shell 2 and the lower connecting shell 1, and to a certain extent, better protecting the fixing rod 12.

[0033] A circuit board 4 is fixedly mounted on the top of the inner wall of the upper connecting shell 2 , and a sensor element is mounted on the surface of the circuit board 4 .

[0034] It should be noted that a circuit board 4 is installed in the upper connecting shell 2 , a sensor element is installed on the circuit board 4 , and a connector for connecting the sensor to an external device or system is provided in the upper connecting shell 2 .

[0035] Sealing gaskets are provided at the top and the open ends of the side walls of the lower connecting shell 1 , and the sealing gaskets are in close contact with the upper connecting shell 2 .

[0036] It should be noted that by setting a sealing gasket on the top of the lower connecting shell 1, after the upper connecting shell 2 is connected to the lower connecting shell 1, the top of the sealing gasket can fit tightly with the upper connecting shell 2, thereby sealing the connection between the upper connecting shell 2 and the lower connecting shell 1, effectively preventing the internal components of the shell from getting damp.

[0037] The two corresponding inner walls of the U-shaped fixing frame 5 are equidistantly provided with strip grooves, and the ends of the U-shaped fixing frame 5 are provided with rectangular grooves, and the elastic connecting plates 6 are located in the rectangular grooves.

[0038] It should be noted that by providing strip grooves at equal distances on the two corresponding inner walls of the U-shaped fixing frame 5 and providing rectangular grooves at the ends of the U-shaped fixing frame 5 , it is possible to save materials and achieve a better stable support effect.
