[0025] See also Figures 1 to 4 , the utility model provides an embodiment 1 of an inflating device for tire testing, comprising a pneumatic jack 1, an air extraction device 2, an inflating assembly and a connecting assembly 3;

[0026] The inflation assembly includes an inflation tube 4, an inflation nozzle 5 and an air inlet 41, and the inflation nozzle 5 and the air inlet 41 are respectively installed at both ends of the inflation tube 4; in addition, the output port of the air extraction device 2 is connected to the air supply pipe 21, the connecting assembly 3 is connected to the air supply pipe 21, and an air inlet 11 is provided at the air inlet of the pneumatic jack 1, and the connecting assembly 3 connects the air inlet 11 and the air inlet 41 and delivers gas to the two; thereby, when performing a leak detection, the staff installs the inflation nozzle 5 on the At the air nozzle of the tire, the pneumatic jack 1 is placed at the bottom of the car; then the air extraction device 2 is turned on, and the air is first extracted and transported to the pneumatic jack 1, so that the pneumatic jack 1 lifts the car, and then the air is extracted and transported to the tire to inflate the tire; thereby meeting the requirements of lifting and inflation in air leakage detection, and no other tools are needed during the detection, and the operation is simple; and only a single air extraction device 2 can be used to drive the jack and the inflation device, and the overall manufacturing cost is low.

[0027] See also Figures 2 to 4Specifically, in the present embodiment 1, the connecting assembly 3 includes a three-way pipe 31 and a plurality of connecting rods 32 connecting the air inlet member 11 and the air inlet member 2 41; in addition, the periphery of the air inlet member 11 is provided with a thread and a threaded tube 6 matched with the thread, and the periphery of the air inlet member 2 41 is provided with a smooth tube 7; a rotating joint 8 is provided between the threaded tube 6 and the smooth tube 7, one end of the rotating joint 8 is rotatably connected to the threaded tube 6, and the other end is rotatably connected to the smooth tube 7; and the two outlets of the three-way pipe 31 are located in the rotating joint 8 and are arranged coaxially with the rotating joint 8, and the inlet of the three-way pipe 31 extends to the outside of the rotating joint 8 and is connected to the gas pipe 21; thereby, when using the present device for jacking, the staff rotates the threaded tube 6 to move it toward the side of the air inlet member 11, When the threaded tube 6 moves, it pulls the rotary joint 8 and the three-way pipe 31 inside it toward the air inlet piece 11, and finally one outlet of the three-way pipe 31 is connected with the air inlet piece 11, and the air extracted by the air extraction device 2 is transported to the pneumatic jack 1 through the three-way pipe 31 and the air inlet piece 11, so as to perform the jacking operation; when using this device for inflation, the staff rotates the threaded tube 6 to move it toward the side of the air inlet piece 41, and the threaded tube 6 pushes the rotary joint 8 and the three-way pipe 31 inside it toward the air inlet piece 41 when it moves, and finally the other outlet of the three-way pipe 31 is connected with the air inlet piece 41, and the air extracted by the air extraction device 2 is transported to the tire through the three-way pipe 31 and the air inlet piece 41, so as to perform the inflation operation.

[0028] See also Figure 5 Specifically, the rotary joint 8 in this embodiment 1 is a pipe with elliptical ring protrusions 81 at both ends, and the end of the threaded pipe 6 close to the rotary joint 8 and the end of the smooth pipe 7 close to the rotary joint 8 are both provided with elliptical ring grooves that cooperate with the elliptical ring protrusions 81; when the elliptical ring protrusion 81 is inserted into the elliptical ring groove, the elliptical ring protrusion 81 is connected to the elliptical ring groove, and at the same time, the gap between the two causes the elliptical ring protrusion 81 to rotate relative to the elliptical ring groove, thereby realizing a rotational connection.

[0029] Preferably, to prevent air leakage during lifting and inflation, the air inlet member 11 and the air inlet member 2 41 in the present embodiment 1 are both valves, and both outlets of the three-way pipe 31 are equipped with inflation nozzles 5 used in conjunction with the valves.

[0031] See also Figure 6Specifically, the utility model proposes an embodiment 2 on the basis of embodiment 1; in this embodiment 2, the connecting assembly 3 is replaced with another structure, which includes a three-way valve 33, and the two outlets of the three-way valve 33 are flange-connected to the air inlet 11 and the air inlet 2 41 respectively; in addition, the inlet of the three-way valve 33 is provided with a valve nozzle, and the air supply pipe 21 is provided with an inflation nozzle 5 matched with the valve nozzle; the air inlet 11 and the air inlet 2 41 are both connected pipes; thereby, when the device is used for jacking, the valve flap of the three-way valve 33 is rotated to connect the inlet of the three-way valve 33 with the air inlet 11, and the air transported through the air supply pipe 21 is transported to the pneumatic jack 1 through the three-way valve 33, so as to perform the jacking operation; and when the device is used for inflation, the valve flap of the three-way valve 33 is rotated to connect the inlet of the three-way valve 33 with the air inlet 2 41, and the air transported through the air supply pipe 21 is transported to the tire through the three-way valve 33, so as to perform the inflation operation.

[0032] It should be noted that, although the operation of Example 2 is simpler than that of Example 1, its maintenance cost is relatively high (the specific reason is that the wearing parts in Example 1 are only the valve nozzle and the inflation nozzle, which are simple to replace and the cost is low; while the three-way valve in Example 2 has a complex structure, has more wearing parts inside and is inconvenient to disassemble, so it is usually replaced as a whole when replaced, which is more costly); in this regard, technical personnel in this field can select the corresponding embodiment for implementation according to actual conditions.

[0033] It should be noted that the air extraction device 2 in the present invention is an air pump, and those skilled in the art may select other air extraction devices 2, such as an air compressor, etc. according to actual conditions.

[0034] It should be noted that the pneumatic jack 1, the air valve and the inflation nozzle 5 in the present invention are all prior arts, and therefore are not described in detail.

At this time, the air extracted by the air extraction device 2 is transported to the pneumatic jack 1 through the three-way pipe 31 and the air inlet part 11 to perform the jacking operation.

[0037] During inflation: the worker rotates the threaded tube 6 to move it toward the side of the air inlet part 41, the threaded tube 6 pushes the rotary joint 8 and the three-way tube 31 inside it to move toward the air inlet part 41, the other outlet of the three-way tube 31 is connected to the air inlet part 41, and the air extracted by the air extraction device 2 is transported to the tire through the three-way tube 31 and the air inlet part 41 to perform the inflation operation.

[0038] Embodiment 2: During jacking: the staff rotates the valve flap of the three-way valve 33 to connect the inlet of the three-way valve 33 with the air inlet 11, and the air transported by the air pipe 21 is transported to the pneumatic jack 1 through the three-way valve 33, thereby performing the jacking operation.

[0039] During inflation: the staff rotates the valve flap of the three-way valve 33 to connect the inlet of the three-way valve 33 with the air inlet 41, and the air delivered by the air delivery pipe 21 is delivered to the tire through the three-way valve 33, thereby performing the inflation operation.
