[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Reference Figure 1-9 The device shown is a test apparatus for testing the mechanical strength of acetylene cylinder packing. It includes a test apparatus body 1, a test block 2, a fixed base 3, and a force application component 4. The fixed base 3 and the force application component 4 are symmetrically arranged on the worktable of the test apparatus body 1. In order to improve the stability of the device when testing the test block 2, a set of fixed plates 5 are provided on the outer wall of the fixed base 3. The fixed plates 5 are provided with two sets of symmetrical limiting posts 6. The force application component 4 is provided with a set of limiting plates 7. The limiting plates 7 are provided with holes that are adapted to the limiting posts 6 so as to improve the stability of the device when using the force application component 4. Clamping blocks are provided at the end of the force application component 4 and on the fixed base 3. During the test, the test block 2 is placed between the clamping blocks. Then, the button on the test apparatus body 1 is operated to control the force application component 4 to push the clamping blocks to one side and detect the pressure of the test block 2.

[0029] To protect the testing environment and avoid frequent cleaning of the workbench of the testing device 1, a set of protective mechanisms is inserted into the limiting plate 7. This mechanism is used to receive materials while preventing material from jumping out during the testing process, thus avoiding potential safety hazards.

[0030] As one implementation method in this embodiment, the protective mechanism includes a set of detachable protective components 8 located below the two sets of clamping blocks. The protective components 8 have an arc-shaped cross-section and an arc-shaped storage groove 80 within them (e.g., [missing information]). Figure 8 As shown), a set of movable parts 13 are slidably connected within the storage slot 80, and the circumference of the movable parts 13 is greater than that of the storage slot 80. Therefore, in the non-working state, a portion of the movable parts 13 protrudes from the storage slot 80 (as shown). Figure 6 As shown, this design is for ease of use; two sets of symmetrical arc-shaped sliding grooves 84 are provided on the inner wall of the receiving groove 80, and a slider 130 adapted to the sliding groove 84 is provided on the end face of the movable part 13, thereby improving the stability of the movable part 13. A set of easy-to-start handles 15 are provided on the part of the movable part 13 that protrudes from the receiving groove 80; after the test block 2 is placed between the two sets of clamping blocks and the equipment is started through the control panel on the main body of the test device 1, the movable part 13 is driven to slide in the receiving groove 80 by the handle 15, and the locking mechanism completes the limiting between the movable part 13 and the protective part 8, forming a ring-shaped shielding space. This shielding space not only catches the falling powder and slag, but also avoids the splashing of the broken material.

[0031] The limiting plate 7 has two sets of symmetrical insertion holes 70, and the end face of the protective component 8 has insertion posts 9 that are compatible with the insertion holes 70. This structure facilitates the quick installation and disassembly of the structure.

[0032] As one embodiment of this invention, the locking mechanism includes: a set of locking strips 14 on the outer end face of the movable member 13, and a hemispherical positioning groove 140 on the end face of the locking strips 14. To accommodate the locking strips 14, a set of through holes 81 communicating with the storage groove 80 are provided on the end face of the protective member 8 (e.g., ...). Figure 4 As shown), two sets of symmetrical telescopic holes 82 are provided on the inner wall of the through hole 81, and a set of positioning pins 10 are slidably connected in the telescopic holes 82. The outer end of the positioning pin 10 is hemispherical, and the outer end of the positioning pin 10 is adapted to the positioning groove 140. In order to enable the positioning pin 10 to extend outward at all times, a set of springs 11 is provided in the telescopic holes 82. In order to ensure the normal use of the springs 11, a fixing bolt 12 is threadedly connected to one end of the telescopic hole 82. Therefore, when the movable part 13 slides in the storage groove 80, after rotating a certain angle, the locking strip 14 is inserted into the through hole 81, and the positioning pin 10 is squeezed in this process. After the positioning groove 140 is aligned with the telescopic hole 82, under the action of the spring 11, the positioning pin 10 is inserted into the positioning groove 140 to achieve the limit.

[0033] To prevent the fixing bolt 12 from falling out of the telescopic hole 82, a locking member 100 is provided on the outer wall of the positioning pin 10, and a locking groove 83 is provided on the inner wall of the telescopic hole 82 for the locking member 100 to slide. The length of the locking groove 83 is shorter than that of the telescopic hole 82. When it is necessary to maintain the spring 11 and the positioning pin 10, the fixing bolt 12 can be unscrewed.

[0034] The working principle of this utility model is as follows: The test block 2 is placed between the fixed base 3 and the force-applying component 4. Then, the test device body 1 is activated, and the force-applying component 4 begins to work, pushing the end clamping block outwards. During this process, the clamping block on the fixed base 3 clamps and limits the test block 2. Then, the handle 15 on the outer wall of the movable part 13 is pulled, causing the movable part 13 to slide within the receiving groove 80. During this process, the movable part 13 is limited by the slider 130 on its end face cooperating with the sliding groove 84, preventing the movable part 13 from falling off. When the movable part 1... 3. After flipping at a certain angle, the locking strip 14 on the movable part 13 is inserted into the through hole 81, and the positioning pin 10 is squeezed during the insertion process, so that the positioning pin 10 is squeezed back into the telescopic hole 82. After the locking strip 14 is fully inserted into the through hole 81, the positioning groove 140 is aligned with the telescopic hole 82. Under the action of the spring 11, the positioning pin 10 is extended and inserted into the positioning groove 140, thereby completing the protection task and avoiding material jumping during the test, which could lead to safety hazards. Then, the corresponding data of the test block 2 is displayed on the display screen of the test device body 1.

[0035] When the inspection is completed and the protective component 8 needs to be cleaned and maintained, it can be quickly removed by plugging in the pin 9 and the socket 70.
