[0026] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments, it should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

[0027] In the related art, some switch housings need to be installed for use in underwater environment. The traditional water pressure detection method for the switch housing is to place the switch housing at different water depths multiple times to detect the water pressure resistance of the switch housing. However, this cannot accurately detect the water pressure value, and is likely to affect the accuracy of water pressure detection. Patent No. CN213148578U discloses a water pressure detection device for a switch housing, which is provided with a support rod in the hollow cylindrical barrel, and a vertical plate is connected to one end of the support rod. The vertical plate can be extruded by water to extrude the outer surface of the switch housing. By providing a pressure sensor, the water pressure value can be accurately detected. However, in the implementation of the above patent, the position of the probe on the pressure sensor is inconvenient to adjust. In order to ensure that the vertical plate can be in contact with the probe, the installation position of the pressure sensor and the vertical plate is required to be accurate, which is inconvenient to operate and implement.

[0028] The present embodiment provides a water pressure detection device for a switch housing, which can conveniently adjust the position of the probe of the pressure sensor to ensure that the vertical plate is in contact with the probe.

[0029] Please refer to Figs. 1-2 In the present embodiment, a water pressure detection device for a switch housing includes a switch housing 10, a pressure rod 20, and a sliding block 30. The switch housing 10 is provided with a lower sleeve 11 and an upper sleeve 12 on the outside. The pressure rod 20 is slidingly inserted into the lower sleeve 11, and the outer end of the pressure rod 20 is provided with a vertical plate 21. The sliding block 30 is slidingly inserted into the upper sleeve 12, and the sliding block 30 is provided with a support rod 31 that is clamped with the upper sleeve 12. A limiting rod 32 is fixedly connected to the support rod 31, and the limiting rod 32 is slidingly clamped with an adjusting cylinder 33 that is screwed to the outside of the upper sleeve 12. The support rod 31 is fixedly connected with a pressure sensor 35, and the probe 36 of the pressure sensor 35 is in contact with the vertical plate 21.

[0030] The technical solution of the present embodiment adjusts the position of the probe 36 of the pressure sensor 35 by rotating the adjusting cylinder 33 to drive the sliding block 30 to move in the upper sleeve 12, so as to conveniently ensure that the vertical plate 21 is in contact with the probe 36.

[0031] In the present embodiment, the upper sleeve 12 and the lower sleeve 11 are both hollow cylindrical, and the upper sleeve 12 and the lower sleeve 11 can be fixedly connected to the outer wall of the switch housing 10 by bolts. The upper sleeve 12 and the lower sleeve 11 are arranged in parallel. During detection, the lower sleeve 11 is located underwater, and the upper sleeve 12 is located above water.

[0032] The pressure rod 20 is in the form of a smooth round rod, is slidably inserted into the lower sleeve 11, and a sealing ring for preventing water from entering is arranged between the pressure rod 20 and the lower sleeve 11, which can also ensure that the pressure rod 20 can slide in the lower sleeve 11. The vertical plate 21 is fixedly connected to the outer end of the pressure rod 20 and is arranged perpendicularly to the pressure rod 20, and the vertical plate 21 is vertically upward.

[0033] The sliding block 30 is in the form of a smooth round rod, is slidably inserted into the upper sleeve 12, and a displacement slot 37 is formed in the lower side wall of the upper sleeve 12 and extends along the axial direction of the upper sleeve 12. The support rod 31 is fixedly connected to the side wall of the sliding block 30 and is arranged along the radial direction of the upper sleeve 12. The support rod 31 extends out of the upper sleeve 12 through the displacement slot 37 and faces the lower sleeve 11. The limiting rod 32 is fixedly connected to the support rod 31 and is arranged in parallel to the support rod 31. The adjusting cylinder 33 is screwed onto the outside of the upper sleeve 12. The annular sliding groove 34 is arranged on the outer wall of the adjusting cylinder 33 and is coaxially arranged with the adjusting cylinder 33. The limiting rod 32 is slidably connected to the inside of the sliding groove 34, and the limiting rod 32 is arranged along the radial direction of the adjusting cylinder 33. The pressure sensor 35 is also fixedly connected to the support rod 31, and the probe 36 of the pressure sensor 35 faces the vertical plate 21 and abuts against the vertical plate 21.

[0034] It should be noted that the sliding and clamping cooperation of the support rod 31 and the displacement slot 37 makes the sliding block 30 unable to rotate in the upper sleeve 12, that is, the sliding block 30 is only allowed to slide along the axial direction of the upper sleeve 12. The sliding and clamping cooperation of the limiting rod 32 and the sliding groove 34 makes the sliding block 30 move synchronously when the adjusting cylinder 33 rotates, thereby achieving the purpose of adjusting the position of the probe 36 of the pressure sensor 35.

[0035] In use, the pressure rod 20 is first pushed inward until the inner end of the pressure rod 20 abuts against the outer wall of the switch housing 10. Then, the position of the probe 36 is adjusted by the adjusting cylinder 33 until the probe 36 abuts against the vertical plate 21. Subsequently, the switch housing 10 is placed in the water tank, and the pressure sensor 35 and the probe 36 are ensured not to be submerged in water. The vertical plate 21 is pressed by the water in the water tank, thereby pushing the vertical plate 21 to press the probe 36 and the pressure rod 20. Since the pressing force of the pressure rod 20 on the switch housing 10 is the same as the pressing force of the vertical plate 21 on the pressure rod 20, the probe 36 is pressed by the vertical plate 21, and the pressure value can be detected. The detected data is displayed on the display screen outside by the pressure sensor 35, and the pressure value can be clearly observed.

[0036] Although the embodiments of the present application have been shown and described above, it is understood that the above-described embodiments are exemplary and are not to be construed as limiting the present application, and that changes, modifications, substitutions and variations can be made by those skilled in the art without departing from the scope of the present application.
