Description

Technical Field

[0001] This utility model relates to a protective device on a universal testing machine, and more particularly to a protective device for measuring the crushing strength of zirconia beads or zirconia structural components. Background Technology

[0002] like Figure 1 As shown, a universal testing machine is a multifunctional mechanical testing instrument that can perform tensile, compressive, and bending mechanical property tests on materials. Its principle mainly involves two aspects: load generation and signal measurement. When measuring the crushing strength of zirconia beads or zirconia structural components, the sample needs to be fixed on the testing machine, and the load is transferred to the sample through a vertically moving plate. During the compression test, the testing machine applies a compressive load through the lower indenter. When a certain pressure is reached, the zirconia beads will be crushed, completing the test.

[0003] However, existing methods for measuring the crushing strength of zirconia beads or zirconia structural components using universal testing machines have the following problems and drawbacks: 1. Existing universal testing machines lack protective covers. Under immense pressure, when zirconia beads or structural components undergo a severe crushing process, they rapidly disintegrate into fine fragments. Due to the instantaneous release of pressure and potential kinetic energy transfer, these fragments scatter at extremely high speeds and wide angles. If these fragments come into contact with personnel during this process, they can cause bodily injury; 2. During the test, fragments of zirconia beads or structural components scatter everywhere, making collection difficult. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a protective device for measuring the crushing strength of zirconia beads or zirconia structural components.

[0005] The present invention adopts the following technical solution:

[0006] A protective device for measuring the crushing strength of zirconia beads or zirconia structural components includes a protective device body, which includes a base frame and a protective cover. The base frame is a cuboid frame with openings at the top and bottom, and a square slot is formed on the cuboid frame. The protective cover is formed by hinged four transparent protective plates to enclose a cuboid frame, and the bottom of the four transparent protective plates of the protective cover is engaged with the slot.

[0007] Preferably, the base frame is a folding base frame, including a first folding arm, a second folding arm, a third folding arm, and a fourth folding arm. The first folding arm and the second folding arm, the second folding arm and the third folding arm, and the third folding arm and the fourth folding arm are hinged together by a pivot and a pivot sleeve. The first folding arm, the second folding arm, the third folding arm, the fourth folding arm, and the pivot sleeve are respectively provided with slots. After the folding base frame is folded to form a cuboid frame, the slots are correspondingly formed into cuboid frame-shaped slots.

[0008] Preferably, among the four transparent protective panels, adjacent transparent protective panels are hinged together by two hinges at the connection point.

[0009] Preferably, the four transparent protective panels are made of tempered glass.

[0010] Preferably, the base frame is equipped with a magnetic attachment at its bottom for attaching to the base of the universal testing machine.

[0011] The beneficial effects of this utility model are: (1) This utility model designs a protective device for measuring the crushing strength of zirconia beads or zirconia structural parts, so as to solve the problem of avoiding the injury to personnel caused by the flying fragments during the testing process using a universal testing machine; (2) The protective device is in the shape of a transparent small box and has the function of collecting test sample fragments; (3) When not in use, the folding base and protective cover are easy to disassemble and fold for storage, saving space.

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0017] Example: Figure 2 and Figure 3As shown, a protective device for measuring the crushing strength of zirconia beads or zirconia structural components includes a protective device body. The protective device body includes a folding base frame 4 and a protective cover 1. The folding base frame includes a first folding arm 5, a second folding arm 6, a third folding arm 7, and a fourth folding arm 8. The first folding arm and the second folding arm, the second folding arm and the third folding arm, and the third folding arm and the fourth folding arm are hinged together by a pivot and a pivot sleeve 9. The first folding arm, the second folding arm, the third folding arm, the fourth folding arm, and the pivot sleeve are respectively provided with slots 10. After the folding base frame is folded to form a cuboid frame, the slots are correspondingly formed into cuboid frame slots. The protective cover is formed by four transparent protective plates 2 hinged together to form a cuboid frame. The bottom of the four transparent protective plates of the protective cover is engaged with the slots.

[0018] The four transparent protective panels are hinged together by two hinges (top and bottom) at their joints. All four panels are made of tempered glass. A magnetic closure is installed at the bottom of the folding base.

[0019] When measuring the crushing strength of zirconia beads or zirconia structural components using a universal testing machine, the protective cover of this device, with its folding base frame featuring slots at the bottom, is folded into a cuboid shape and fixed around the lower pressure plate of the universal testing machine. Then, the four foldable tempered glass panels on the protective cover are folded into a cuboid shape and placed in the slots formed on the folding base frame. The lower pressure plate of the universal testing machine is thus protected within the cuboid surrounded by protective glass. When the universal testing machine crushes the zirconia beads or zirconia structural components, the flying debris is contained within the glass cover. After use, the device can be easily and quickly removed, saving storage space when folded.

[0020] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
