[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] Please see Figs. 1-2 This utility model embodiment includes: an impact resistance testing device for inflatable protective gear, comprising a base plate 1, two vertically mounted support rods 2 on the base plate 1, a test platform 3 on the base plate 1, a control cabinet 4 beside the test platform 3, a control unit (not shown in the figure) in the control cabinet 4, a force contact plate 5 on the test platform 3, a force sensor 6 on the force contact plate 5, the force sensor 6 being signal-connected to the control unit, and a magnet mounting plate 7 on the top of the two support rods 2. An electromagnet 8 is provided on the magnet mounting plate 7. The electromagnet 8 is electrically connected to the control unit via a wire. An impact hammer assembly is slidably mounted on the two support rods 2. The impact hammer assembly includes a load plate 9. Bearing seats 10 are respectively provided at both ends of the load plate 9. A linear bearing 11 is vertically mounted inside the bearing seat 10. The linear bearing 11 is sleeved on the two support rods 2. An iron plate 12 is provided on the top of the load plate 9. An impact block 13 is provided on the bottom of the load plate 9. The bottom surface of the impact block 13 is a downwardly convex arc surface.

[0014] Preferably, the impact block 13 is detachably mounted on the bottom of the load plate 9.

[0015] Preferably, the impact block 13 is located above the force-bearing contact plate 5.

[0016] Preferably, the bearing seats 10 are located at the four corners of the load plate 9, so that the four bearing seats 10 can be evenly installed on the load plate 9, so that the load plate 9 is subjected to balanced forces.

[0017] When the impact resistance testing device for inflatable protective gear of this utility model is working, the inflatable protective gear to be tested is placed on the force contact plate 5. The control unit energizes the electromagnet 8 to make the electromagnet 8 magnetic. Then, the impact hammer assembly is pushed upward by hand, and the load plate 9 slides upward along the two support rods 2. When it reaches the top of the two support rods 2, the iron plate 12 is attracted and fixed together with the magnet mounting plate 7 under the magnetic attraction of the electromagnet 8. Then, the electromagnet 8 is de-energized to make the electromagnet 8 lose its magnetism. The load plate 9 falls freely under the action of gravity, and the impact block 13 falls and hits the inflatable protective gear on the force contact plate 5. The inflatable protective gear is impacted by the falling impact block 13. At the same time, the force sensor 6 senses the magnitude of the impact force and feeds back the impact force signal to the control unit. The control unit judges the impact condition of the inflatable protective gear and judges the impact resistance performance of the inflatable protective gear in combination with the appearance inspection, and judges whether the inflatable protective gear meets the impact resistance requirements.

[0018] This utility model discloses an impact resistance testing device for inflatable protective gear. It is used for impact resistance testing of inflatable protective gear and has high testing efficiency and safe operation. By changing the impact component, the impact block, it can be adapted to the impact resistance testing of different inflatable protective gear, thus expanding the application range of the testing device.

[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
