Description

Technical Field

[0001] This utility model relates to the field of air pressure measuring instruments, and in particular to an air pressure measuring device for a braking system. Background Technology

[0002] Traditional braking system air pressure measurement devices are often designed with a focus on the sealing and stability of the joints to ensure accurate air pressure measurements. Therefore, the joint design is typically complex, requiring assurance against leaks or loosening during connection. When the air pressure measurement device is in operation, the pipes need to be cumbersomely connected and disconnected at the air inlet. This results in time-consuming and labor-intensive connection and disconnection of the pipes at the joints, hindering quick connection methods.

[0003] Therefore, it is essential to provide a brake system air pressure measuring device to address the shortcomings of existing technologies. Utility Model Content

[0040] The present invention will be further described in conjunction with the following embodiments.

[0041] Example 1.

[0042] like Figure 1-3 As shown, a brake system air pressure measuring device includes an air reservoir 1. An air reservoir inlet 2 and an air reservoir outlet 3 are provided on one side of the air reservoir 1. A four-way adapter 4 and a straight connector 5 are respectively installed at the air reservoir inlet 2 and the air reservoir outlet 3. Nylon tubes 6 are installed on both the four-way adapter 4 and the straight connector 5. An air pressure measuring instrument 7 is installed at one end of the four-way adapter 4. A pressure sensor 8 is installed on the air pressure measuring instrument 7. The pressure sensor 8 is connected to an LCD display 9.

[0043] The pressure sensor 8 transmits the air pressure value measured by the barometer 7 to the LCD display 9 via Bluetooth. The operator reads the air pressure value through the software on the LCD display 9. The barometer 7, pressure sensor 8 and LCD display 9 are all existing technologies and will not be described in detail here.

[0044] like Figure 1-3 As shown, the four-way adapter 4 includes two interfaces A10 and two interfaces B11. The two interfaces A10 are respectively connected to nylon tubes 6, and the two interfaces B11 are respectively connected to the air inlet 2 of the air tank and the air pressure measuring instrument 7. The interior of the two interfaces A10 is a funnel structure. The quick-connect assembly 12 is snapped into the interior of the two interfaces A10. The quick-connect assembly 12 is fixedly installed at the end of the nylon tube 6. The silicone sealing ring 13 is snapped into the exterior of the quick-connect assembly 12. The silicone sealing ring 13 is fixedly installed with the interface A10.

[0045] Air is introduced into the air reservoir 1 through the nylon tube 6 connected to the air reservoir inlet 2, and air is discharged through the nylon tube 6 connected to the air reservoir outlet 3. When the air pressure measuring instrument 7 is used for operation, the four-way adapter 4 connected to the air reservoir inlet 2 can save time and effort spent on connecting and disconnecting the pipeline through the quick-connect assembly 12, so as to achieve the purpose of quick connection.

[0046] like Figure 1-3 As shown, the quick-connect assembly 12 includes a positioning ring 14. Four spring clips 15 are hinged to the other end of the positioning ring 14. The spring clips 15 are engaged with the end of the interface A10. One end of the positioning ring 14 is fixedly installed on the outside of the nylon tube 6. A telescopic spring A16 is installed inside the positioning ring 14. A sleeve 17 is installed on the telescopic spring A16. One end of the sleeve 17 abuts against the funnel-shaped slope inside the interface A10. An adjustable fastening component 18 is slidably installed on the inner side of the sleeve 17. The inner side of the adjustable fastening component 18 is fixedly installed on the end of the nylon tube 6. The adjustable fastening component 18 is fixedly engaged with the funnel-shaped slope at the interface A10.

[0047] like Figure 1-3 As shown, the adjustable fastening component 18 includes a positioning sleeve 19. The outer side of the positioning sleeve 19 is slidably connected to the inner side of the sleeve 17. The inner side of the positioning sleeve 19 is fixedly installed to the outer side of the end of the nylon tube 6. Two grooves 20 are symmetrically opened on the positioning sleeve 19 near the end of the nylon tube 6. A telescopic spring B21 is installed in each groove 20. A circular locking block 22 is installed on the telescopic spring B21. The circular locking block 22 is fixedly engaged with the funnel-shaped slope at the interface A10.

[0048] The locating ring 14, which is fixedly installed with the nylon tube 6, is equipped with a spring clip 15 that can be fixedly engaged with the end of the interface A10, thereby achieving axial clamping of the nylon tube 6.

[0049] The telescopic spring A16 installed inside the positioning ring 14 is connected to the sleeve 17. The sleeve 17 and the positioning sleeve 19 are slidably installed. During the insertion of the nylon tube 6 into the interface A10, one end of the sleeve 17 abuts against the funnel-shaped slope inside the interface A10, which further causes the positioning sleeve 19 inside the sleeve 17 to drive the end of the nylon tube 6 to slide out of the sleeve 17. At the same time, the circular locking block 22 installed in the groove 20 of the positioning sleeve 19 also slides out of the sleeve 17. The circular locking block 22 is popped out by the elastic force of the telescopic spring B 21 and fixedly locked with the funnel-shaped slope at the interface A10, which further realizes the radial locking of the nylon tube 6.

[0050] like Figure 1-3 As shown, a silicone pad 23 is installed on one end of the positioning sleeve 19 near the groove 20. The silicone pad 23 abuts against the funnel-shaped slope inside the interface A10. The silicone pad 23 can make the positioning sleeve 19 fit more tightly inside the interface A10, ensuring the airtightness of the whole device.

[0051] In this embodiment, four spring clips 15 are provided, but the specific number of spring clips 15 can be adjusted according to the actual situation and is not limited to four. When the size of the positioning ring 14 is larger, more spring clips 15 can be used to ensure the structural stability of the device.

[0052] In this invention, the air reservoir 1 receives air through a nylon tube 6 connected to the air inlet 2 and exits air through the nylon tube 6 connected to the air outlet 3. When using a barometer 7, the four-way adapter 4 connected to the air inlet 2 can save time and effort in connecting and disassembling the pipeline through the quick-connect assembly 12, achieving a quick connection. The nylon tube 6 is fixedly engaged with the end of the interface A10 by a spring clip 15 hinged to the positioning ring 14, thus achieving the purpose of quick connection. Axial clamping is achieved by connecting sleeve 17 to telescopic spring A16 installed inside positioning ring 14. Sleeve 17 and positioning sleeve 19 are slidably installed. During the insertion of nylon tube 6 into interface A10, one end of sleeve 17 abuts against the funnel-shaped slope inside interface A10, which further causes the positioning sleeve 19 inside sleeve 17 to drive the end of nylon tube 6 to slide out of sleeve 17. At the same time, the circular locking block 22 installed in the groove 20 of positioning sleeve 19 also slides out of sleeve 17. The circular locking block 22 is popped out by the elastic force of telescopic spring B 21 and fixedly engaged with the funnel-shaped slope at interface A10, further achieving radial clamping of nylon tube 6.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
