Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure gauges, and in particular to a new energy charging tire pressure gauge. Background Art

[0002] A tire pressure gauge is a tool for measuring the tire pressure of a vehicle. Air pressure is the lifeline of a tire, and both too high and too low pressures will shorten its service life. If the air pressure is too low, the tire body deformation will increase, and cracks will easily appear on the sidewalls. At the same time, flexion movement will occur, leading to excessive heat generation, causing rubber aging, cord layer fatigue, and cord breakage. Too low air pressure will also increase the tire contact area and accelerate shoulder wear. Too high air pressure will cause excessive stretching and deformation of the tire cord, reduce tire body elasticity, and increase the load on the car while driving. In the event of an impact, internal cracks and explosions will occur. At the same time, too high air pressure will accelerate crown wear and reduce rolling resistance. Most tire pressure gauges are now rechargeable models for easy outdoor use.

[0003] Traditional tire pressure gauges have some shortcomings. When inflating or deflating a tire, workers need to operate a pressure plate to control the gas flow. The pressure plate is a structure that blocks the gas inside the tire pressure gauge by controlling it through a lever. At the same time, since it needs to be controlled by a lever, it resets relatively slowly, and thus cannot be quickly reset, which hinders gas flow. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a new energy charging tire pressure gauge includes a connecting seat 1, the upper end of the connecting seat 1 is equipped with a tire pressure gauge body 2, one end of the connecting seat 1 is fixedly connected to a connecting handle 4, the lower end of the connecting handle 4 is provided with a control groove 6, the upper end of the connecting handle 4 is fixedly connected to a supporting bin 7, the outer side of the connecting seat 1 is movably connected to a pressure plate 8 through a rotating shaft, the inner side of the supporting bin 7 is slidably connected to a regulating rod 9, the inner side of the control groove 6 is threadedly connected to a mounting bin 10, the inner bottom of the mounting bin 10 is fixedly connected to a spring 11, the inner side of the spring 11 is sleeved with a limiting block 12, the upper end of the limiting block 12 is fixedly connected to a plugging head 13, the inner side of the mounting bin 10 is slidably connected to a limiting rod 14, the outer side of the limiting rod 14 is fixedly connected to a guide block 15, and the lower end of the regulating rod 9 is fixedly connected to the upper end of the limiting rod 14.

[0021] In this embodiment, a mounting groove 16 is provided on the outer side of the guide block 15, and a sealing ring 17 is sleeved on the inner side of the mounting groove 16. A slider 18 is fixedly connected to the outer side of the limit rod 14 near the upper side of the guide block 15. The support bin 7 and the connecting handle 4 are connected, the upper end of the regulating rod 9 is in contact with the inner top of the pressure plate 8, the plugging head 13 is in contact with the mounting bin 10, the outer side of the slider 18 is slidably connected to the inner side of the support bin 7 near the lower side of the regulating rod 9, the outer side of the guide block 15 is slidably connected to the inner side of the support bin 7 near the lower side of the slider 18, the shape of the guide block 15 is truncated cone, the sealing ring 17 is in contact with the inner wall of the inner side of the support bin 7, and the main material of the sealing ring 17 is rubber.

[0022] Specifically, press the pressure plate 8 to rotate it downward, and press the control rod 9 downward, so that the control rod 9 drives the limit rod 14 to slide downward, and the slider 18 and the guide block 15 move along with the limit rod 14. At the same time, the limit rod 14 drives the plugging head 13 to move downward, so that the plugging head 13 compresses the spring 11 downward, and the plugging head 13 no longer contacts the mounting chamber 10, so that the gas can flow through the connecting handle 4 to the inner side of the connecting seat 1, and then inflate the tire. If the tire pressure reaches the normal value, release the pressure plate 8, so that the spring 11 is elastically released. By pushing the plugging head 13 upward and causing the plugging head 13 to drive the limiting rod 14 to move upward, the plugging head 13 contacts the installation bin 10 and blocks the installation bin 10, thereby causing the plugging head 13 to block the flow of gas. By loosening the pressure plate 8, the spring 11 pushes the plugging head 13 upward under the elastic action, and causes the plugging head 13 to contact the installation bin 10 and block the installation bin 10, thereby achieving the purpose of facilitating the plugging head 13 to block the flow of gas. Under the elastic action of the spring 11, the plugging head 13 can be quickly reset, thereby quickly blocking the flow of gas.

[0023] In this embodiment, a hose 3 is installed at the other end of the connecting seat 1 , and a docking ring 5 is installed at one end of the connecting handle 4 .

[0024] Specifically, the hose 3 is connected to the inflation port of the tire, and then the docking ring 5 is connected to the external inflation device, so that the tire can be inflated.

[0025] Working principle:

[0026] When in use, first charge the tire pressure gauge body 2 so that the tire pressure gauge body 2 can be used outdoors. When the tire pressure needs to be monitored, connect the hose 3 to the tire inflation port, and then connect the docking ring 5 to the external inflation device, and then press the pressure plate 8 to rotate the pressure plate 8 downward, and make the pressure plate 8 press the control rod 9 downward, so that the control rod 9 drives the limit rod 14 to slide downward, and makes the slider 18 and the guide block 15 move with the limit rod 14. At the same time, the limit rod 14 drives the plug head 13 to move downward, so that the plug head 13 compresses the spring 11 downward, and makes the plug head 13 no longer contact the installation chamber 10, so that the gas can flow through the connecting handle 4 to the inner side of the connecting seat 1, and then the tire is inflated, and the tire pressure gauge body 2 senses the gas, and the air from the tire enters the tire pressure gauge body 2, and the gas pushes the strain gauge in the tire pressure gauge body 2, thereby producing The bending strain gauge changes its resistance value, so that the resistance change is input into the microprocessor and the resistance change is converted into a binary signal for driving the LCD reading, so that the tire pressure gauge body 2 can clearly display the tire pressure. If the tire pressure reaches the normal value, the pressure plate 8 is released, and the spring 11 pushes the plug 13 upward under the elastic action, and the plug 13 drives the limit rod 14 to move upward, so that the plug 13 contacts the installation chamber 10, and the plug 13 blocks the installation chamber 10, so that the plug 13 blocks the gas circulation. By releasing the pressure plate 8, the spring 11 pushes the plug 13 upward under the elastic action, and the plug 13 contacts the installation chamber 10, and the plug 13 blocks the installation chamber 10, which can achieve the purpose of facilitating the plug 13 to block the gas circulation, and under the elastic action of the spring 11, the plug 13 can be quickly reset, thereby quickly blocking the gas flow.
