[0026] Next, in conjunction with the attached Figures 1-4 The present utility model will be further described. To solve the problems existing in the background technology, the present application proposes a pressure detection device for a terminal pressing machine, including: a pressure gauge 1 and a reminder component 2.

[0027] The pressure gauge 1 includes a seat body 101, a dial 102 installed on the top of the seat body 101, and a pointer structure 103 installed on the top of the dial 102. A Bourdon tube is installed in the seat body 101. As the pressure of the liquid or gas increases, the pressure inside the Bourdon tube will cause it to deform, and the deformation is proportional to the pressure value;

[0028] As Figures 1-4 shown, the reminder component 2 is installed on the top of the dial 102 and corresponds to the pointer structure 103. The reminder component 2 is used to adjust the limit value according to the use requirements and stop the terminal pressing work when the limit value is reached;

[0029] The reminder component 2 includes an adjustment structure 201 and a stop structure 202 installed on top of the adjustment structure 201. A rotating shaft 3 is installed on top of the seat body 101. The adjustment structure 201 includes a transparent disk 2011 slidably sleeved outside the rotating shaft 3, a toothed ring 2012 fixedly installed outside the transparent disk 2011, an adjustment box 2013 fixedly welded to one side of the seat body 101, and a gear 2014 installed on top of the adjustment box 2013. An adjustment motor is installed inside the adjustment box 2013 through bolts. The gear 2014 is fixedly welded to the output shaft of the adjustment motor and meshes with the toothed ring 2012.

[0030] Further, the stop structure 202 includes a limit guiding column 2021 fixedly installed on top of the transparent disk 2011, a guiding plate 2022 slidably sleeved outside the limit guiding column 2021, a hemispherical top 2023 fixedly welded between the two guiding plates 2022, a return spring 2024 welded between the hemispherical top 2023 and the transparent disk 2011, an induction column 2025 fixedly installed on top of the transparent disk 2011, and an induction plate 2026 fixedly welded to the bottom of the hemispherical top 2023. The return spring 2024 is sleeved outside the induction column 2025. When the induction column 2025 contacts the induction plate 2026, it controls the press-end machine to stop working.

[0031] Furthermore, the pointer structure 103 includes a pointer plate 1031 fixedly welded outside the rotating shaft 3, a triangular plate 1032 fixedly welded to one end of the pointer plate 1031, and an arc-shaped plate 1033 fixedly welded to the bottom of the pointer plate 1031. The arc-shaped plate 1033 corresponds to the hemispherical top 2023.

[0032] Furthermore, scale lines 4 are provided on the dial 102. The transparent disk 2011 is installed on top of the dial 102, and the transparent disk 2011 is made of a transparent material.

[0033] For those skilled in the art to fully understand the technical solution, the following is an overall overview of this application:

[0034] During use, the staff installs the pressure gauge 1 in the pressure system of the terminal pressing machine, ensures connection to the test point, starts the terminal pressing machine, and begins the pressing operation. During this process, the pressure inside the terminal pressing machine gradually increases, and the pressure is transmitted through the medium to the Bourdon tube inside the seat body 101. As the pressure of the liquid or gas increases, the pressure inside the Bourdon tube causes it to deform, and the deformation is proportional to the pressure value. The displacement of the Bourdon tube is mechanically converted into the rotation of the rotating shaft 3, and the rotating shaft 3 drives the pointer plate 1031 to rotate. The pointer plate 1031 drives the triangular plate 1032 and the arc plate 1033 to move. When the pressure value reaches the limit value, the arc plate 1033 presses the hemispherical top 2023, and the hemispherical top 2023 drives the guide plate 2022 to slide on the limit guide post 2021. The hemispherical top 2023 presses the return spring 2024 and drives the induction plate 2026 to move. When the induction plate 2026 contacts the induction post 2025, the terminal pressing machine stops the pressing work, and the central control console issues an alarm reminder for the staff to adjust the work, avoiding the production of defective products due to the staff's failure to detect in time. If the staff needs to adjust the pressure limit value, the adjustment motor in the adjustment box 2013 drives the gear 2014 to rotate, and the gear 2014 drives the transparent disk 2011 to rotate through the toothed ring 2012, thereby adjusting the position of the stop structure 202. The position can be accurately adjusted according to the scale line 4.
