Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 3A fire-fighting gas cylinder explosion test device includes a housing 1, a sealing door 2 on the front of the housing 1, an observation window 3 on the front of the sealing door 2, and multiple connection holes 4 on the upper surface of the housing 1, mainly used for connecting the test device and test instruments. A fixing mechanism is also included, comprising a fixing component and a telescopic component. The fixing component includes a movable seat 5 slidably connected within the housing 1, a groove 6 on the upper surface of the movable seat 5, and limiting grooves 7 on both side walls of the housing 1. Movable blocks 8 are slidably connected within each limiting groove 7, and both movable blocks 8 are fixedly connected to the side walls of the movable seat 5. A bidirectional threaded rod 9 is provided within the groove 6, and the bidirectional threaded rod 9 is rotatably connected to the side walls of the two movable blocks 8 via bearings. Nuts 10 are threadedly connected to the opposite thread sections of the bidirectional threaded rod 9. The upper surface of the two fixed clamping seats 11 is fixedly connected to the upper surface of the two fixed clamping seats 11. The upper surface of the two fixed clamping seats 11 is fixedly connected to the support rod 12. The side wall of the top of the two support rod 12 is fixedly connected to the fixed clamping plate 13. The two nuts 10 are located in the groove 6. The bottom surface of the two fixed clamping seats 11 is in contact with the upper surface of the movable seat 5, ensuring that the two nuts 10 can properly engage with the double-threaded rod 9. At the same time, the two movable seats 5 can move smoothly. The upper surface and bottom surface of the two movable blocks 8 are in contact with the inner top surface and inner bottom surface of the two limiting slide grooves 7, respectively, so that the movable seat 5 can move smoothly. The two fixed clamping seats 11 and the fixed clamping plate 13 are located inside the housing 1. The side end of the double-threaded rod 9 is fixedly connected to a rotating handle for easy operation by the staff.

[0025] The telescopic assembly includes an electric push rod 14 fixedly connected to the back of the housing 1 via a bracket. The output end of the electric push rod 14 is fixedly connected to the back of the movable seat 5. Two guide rods 15 are fixedly connected to the back of the movable seat 5. Both guide rods 15 are slidably connected to the back of the housing 1. The back of the housing 1 is provided with a through hole 16, and the output end of the electric push rod 14 passes through the through hole 16.

[0026] The working principle of this utility model is as follows: When it is necessary to fix the gas cylinder to be tested, open the sealing door 2, and then start the electric push rod 14. The output end of the electric push rod 14 will push the moving seat 5 to move, thereby sliding it out of the housing 1, which facilitates the fixing of the gas cylinder to be tested. After the moving seat 5 extends out of the housing 1, place the gas cylinder to be tested between the two fixed clamping seats 11. Then, rotate the double-threaded rod 9 by turning the handle. Under the restriction of the fixed clamping seats 11 and the moving seat 5, the two nuts 10 will engage with the double-threaded rod 9, and then the two nuts 10 will move towards each other. When it is necessary to fix the gas cylinder, the gas cylinder to be tested can be fixed. When the cylinder is fixed, the two nuts 10 move closer to each other, which in turn moves the two fixing clamps 11 closer to each other. The two fixing clamps 11 move the two fixing clamps 13 closer to each other through the support rod 12, until the two fixing clamps 11 and the fixing clamps 13 are tightly attached to both sides of the cylinder body, thus completing the clamping and fixing of the cylinder. The operation is convenient and efficient, and the fixing effect is good. After the cylinder is fixed, the electric push rod 14 is used to retract the moving seat 5 and return it to the housing 1. Then the sealing door 2 is closed, and the test results are observed through the observation window 3, which helps to improve the practicality and safety of the device.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
