Technical Field

[0001] This utility model relates to the technical field of fire extinguisher testing devices, specifically an impact and flattening testing device for fire extinguishers. Background Technology

[0002] An impact and crushing test apparatus for fire extinguishers typically comprises multiple components to achieve comprehensive testing of fire extinguishers. This apparatus not only has impact testing capabilities but also crushing testing capabilities, thereby ensuring that the quality and performance of fire extinguishers meet relevant standards.

[0003] During impact and crushing tests on fire extinguishers, the extinguishers may burst or bounce, which could easily injure operators. To address these issues, this application presents an impact and crushing test device for fire extinguishers. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an impact and flattening test device for fire extinguishers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an impact and flattening test device for fire extinguishers, comprising a base, a gantry frame fixed at the middle of the top of the base, an impact device and a flattening device installed downwards at the top of the gantry frame, a first groove opened at the top of the base directly below the gantry frame, a placement platform slidably connected in the first groove, a first motor installed in the first groove, a threaded rod fixed at the output end of the first motor, the threaded rod being threadedly connected to the placement platform, arc-shaped placement blocks symmetrically fixed on the placement platform, and a protective mechanism for protecting the operator provided on the base, the protective mechanism comprising two sets of protective components, each protective component comprising an I-beam groove, two I-beam grooves symmetrically opened at the top of the base, the two I-beam grooves being respectively located on both sides of the gantry frame, a movable block slidably connected in the I-beam groove, a protective net frame fixed at the top of the movable block, the size of the protective net frame being the same as the opening size of the gantry frame, an electric telescopic rod installed in the I-beam groove, the output end of the electric telescopic rod being fixed on the movable block.

[0008] To further enhance the protective strength of the anti-slip mesh frame, this utility model is improved by adding reinforcing ribs fixed inside the protective mesh frame.

[0009] To prevent slippage when placing fire extinguishers, this invention is improved by symmetrically fixing anti-slip blocks at the top of the arc-shaped placement block.

[0010] To make the moving block more stable during movement, this utility model is improved by having two limiting rods symmetrically fixed inside the I-shaped sliding groove, the limiting rods passing through the moving block and slidably connected to it.

[0011] To prevent the device from moving under external force during operation, the present invention is improved by fixing multiple support legs at the bottom of the base, and the bottom of the support legs is provided with anti-slip texture.

[0012] To prevent the protective net frame from colliding with the I-beam slide rail, this utility model is improved by setting the edge of the I-beam slide rail near the gantry frame as a bevel.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an impact and flattening testing device for fire extinguishers, which has the following beneficial effects:

[0015] This fire extinguisher impact and flattening test device, with its protective mechanism, allows the fire extinguisher to be placed inside the protective mechanism during testing, effectively preventing accidental injury to operators from the fire extinguisher tank bursting or bouncing. It also features both impact and flattening devices, enabling the same device to perform two types of tests. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 An impact and flattening testing device for fire extinguishers includes a base 1. A gantry frame 2 is fixed at the middle of the top of the base 1. An impact device 3 and a flattening device 4 are installed downwards at the top of the gantry frame 2. A first groove 5 is formed directly below the gantry frame 2 at the top of the base 1. A placement platform 6 is slidably connected within the first groove 5. A first motor 7 is installed within the first groove 5. A threaded rod 8 is fixed to the output end of the first motor 7. The threaded rod 8 is threadedly connected to the placement platform 6. Arc-shaped placement blocks 9 are symmetrically fixed on the placement platform 6. The base 1 is equipped with... The system includes a protective mechanism for operator protection. The protective mechanism comprises two sets of protective components, each including an I-beam slide groove 10. The two I-beam slide grooves 10 are symmetrically located at the top of the base 1 and are respectively located on both sides of the gantry frame 2. A movable block 11 is slidably connected within the I-beam slide groove 10. A protective net frame 12 is fixed to the top of the movable block 11. The size of the protective net frame 12 is the same as the opening size of the gantry frame 2. An electric telescopic rod 13 is installed within the I-beam slide groove 10, and the output end of the electric telescopic rod 13 is fixed to the movable block 11.

[0023] When this device is in use, if a test is required, the fire extinguisher is placed on the arc-shaped placement block 9, and the first motor 7 is started to drive the threaded rod 8 to rotate. The placement platform 6, which is threaded onto the threaded rod 8, moves the fire extinguisher along the first slide groove 5 to the direct below the corresponding device. The two electric telescopic rods 13 are started to move the moving blocks 11 on both sides of the gantry frame 2 along the I-shaped slide groove 10 toward the gantry frame 2. The moving blocks 11 move the protective net frame 12 closer to the gantry frame 2 and make the protective net frame 12 contact the gantry frame 2, so that the fire extinguisher, impact device 3 and flattening device 4 are placed in the space closed by the two protective net frames 12. At this time, the impact device 3 or flattening device 4 is started to conduct the test. The test situation is observed through the protective net frame 12. If the fire extinguisher explodes or bounces, the operator will be protected by the protective net frame 12.

[0024] In actual use, it was found that the fire extinguisher may break through the protective net frame 12. In order to strengthen its protective strength, in this embodiment, the protective net frame 12 is fixed with a reinforcing rib 14.

[0025] In actual use, it was found that the fire extinguisher would slide on the arc-shaped placement block 9. In order to avoid the above problem, in this embodiment, the top of the arc-shaped placement block 9 is symmetrically fixed with anti-slip blocks 15.

[0026] In actual use, it was found that in order to make the movement of the moving block 11 more stable, in this embodiment, two limiting rods 16 are symmetrically fixed in the I-shaped slide groove 10. The limiting rods 16 pass through the moving block 11 and are slidably connected to it.

[0027] In actual use, it was found that the device is easily moved by external forces during operation. In order to avoid the above problem, in this embodiment, a plurality of support legs 17 are fixed at the bottom end of the base 1, and the bottom end of the support legs 17 is provided with anti-slip texture.

[0028] In actual use, it was found that when the moving block 11 moves the protective net frame 12, it is easy to collide with the edge of the I-beam slide 10. In order to avoid the above problem, in this embodiment, the edge of the I-beam slide 10 near the gantry frame 2 is set as a bevel.
