DETAILED DESCRIPTION

[0017] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0018] Embodiment 1:

[0019] like Figure 1-3 As shown, a blade-type tire burst test device comprises a base plate 1, a rotating shaft 2, and a puncture assembly arranged on the rotating shaft 2. The rotating shaft 2 can be rotatably connected to the base plate 1 through a bearing seat. A reset assembly is arranged on the rotating shaft 2. The reset assembly is used to drive the rotating shaft 2 to rotate so that the puncture assembly is retracted. One end of the base plate 1 is hingedly connected to a movable baffle 3, and the movable baffle 3 is connected to a locking assembly. The locking assembly is locked in the same position as the rotating shaft 2 so that the puncture assembly is in an erected state. The locking assembly comprises a sliding pull rod 41, a positioning latch 42, a compression spring 43 and A pull rope 44 and a sliding rod 41 are slidably connected so that they can slide back and forth between the rotating shaft 2 and the movable baffle 3. The sliding rod 41 is connected to the positioning pin 42 at one end close to the rotating shaft 2. A positioning slot 21 cooperating with the positioning pin 42 is provided on the rotating shaft 2. The other end of the sliding rod 41 is connected to the movable baffle 3 through a pull rope 44. A compression spring 43 is provided on the sliding rod 41. Through the action of the compression spring 43, the movable baffle 3 is pulled up and the positioning pin 42 is inserted into the positioning slot 21, so that the rotating shaft 2 is fixed so that the puncture assembly is in an upright state.

[0020] Specifically, the sliding rod 41 is a "T"-shaped rod, which is slidably connected in a limiting sleeve 45, the limiting sleeve 45 is fixed to the bottom plate 1, and the compression spring 43 is sleeved on the "T"-shaped rod and located between the end of the "T"-shaped rod and the end of the limiting sleeve 45.

[0021] Specifically, the reset assembly is a tension spring 5, which drives the rotating shaft 2 to rotate so that the puncture assembly is retracted. One end of the tension spring 5 is connected to the rotating shaft 2, and the other end is connected to the bottom plate 1 or the buffer plate 7. The tension spring 5 can be one or more. Figure 2 There are two in the middle.

[0022] Specifically, the puncture assembly includes a blade 61 and a puncture needle 62.

[0023] In some embodiments, the other end of the bottom plate 1 is connected to a buffer plate 7 , and the buffer plate 7 has a slope to mitigate the collision between the tire and the device, thereby avoiding excessive impact on the device.

[0024] Preferably, a buffer rib 8 is provided on the bottom plate 1 between the movable baffle 3 and the rotating shaft 2. The buffer rib 8 has a slope, which also plays a mitigating role to avoid excessive impact on the device.

[0025] The working principle of the utility model is as follows: in the initial state, the positioning pin 42 is inserted into the positioning slot 21 to fix the rotating shaft 2. At this time, the puncturing assembly is in an upright state (i.e., it can puncture the tire) and the movable baffle 3 is in an upright state under the action of the compression spring 43. The vehicle tire is in the following manner: Figure 2 When the vehicle moves in the opposite direction, the front tire of the vehicle first passes through the buffer plate 7 and then is punctured by the puncturing assembly. At this time, the vehicle will continue to move forward, and the front tire will press down the movable baffle 3. At this time, the movable baffle 3 will pull the sliding rod 41 through the pull rope 44 to overcome the force of the compression spring 43 and move to one side of the movable baffle 3. The sliding rod 41 drives the positioning pin 42 to disengage from the positioning slot 21. At this time, the rotating shaft 2 is driven to rotate under the action of the reset assembly to retract the puncturing assembly, thereby not puncturing the rear tire of the vehicle.

[0026] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
