It mainly winds and fixes the packing material through a first fixing component and a second fixing component, symmetrically tensions the packing material through a first tensioning component and a second tensioning component, and displays the detection value of the pressure sensor through a display, having the advantages of convenient use and a relatively large detection length range.

[0053] The following examples are used to illustrate in detail a device for detecting the strength of a fire-fighting packing material according to the present application.

[0054] In this embodiment, as Figure 1 shown, the device for detecting the strength of a fire-fighting packing material includes: a workbench 1;

[0055] A first fixing component 2 and a second fixing component 3, symmetrically arranged on the workbench 1, both used for fixing the packing material;

[0056] A first tensioning component 4 and a second tensioning component 5, symmetrically arranged on the workbench 1, both used for tensioning the packing material;

[0057] A sliding member 6, slidably arranged on the workbench 1;

[0058] A driving mechanism 7, arranged on the workbench 1, connected to the sliding member 6, used for driving the sliding member 6 to move;

[0059] A pressure sensor 8, arranged on the sliding member 6, used for abutting against the packing material;

[0060] A display 9, electrically connected to the pressure sensor 8, used for displaying the detection value of the pressure sensor 8.

[0061] In this technical solution, the workbench 1 is horizontally or vertically arranged and can be adjusted in angle as needed. Subsequently, the description will be based on the horizontal arrangement. The first fixing component 2 and the second fixing component 3 are symmetrically and fixedly arranged on the left and right sides of the workbench 1. The first tensioning component 4 and the second tensioning component 5 are symmetrically fixed on the workbench 1 from left to right and are arranged between the first fixing component 2 and the second fixing component 3.

[0062] The workbench 1 is provided with an inverted T-shaped chute for the sliding member 6 to slide. The sliding member 6 is snap-connected to the chute and can slide back and forth. The sliding member 6 is arranged on the front side of the driving mechanism 7. The pressure sensor 8 is fixed on the front side of the sliding member 6, and the display 9 is fixed on the workbench 1. The display 9 is electrically connected to the pressure sensor 8. When the pressure sensor 8 is subjected to pressure, the display 9 synchronously displays the value of the pressure sensor 8.

[0063] In this embodiment, the first fixing component 2 includes:

[0064] The base 201 is fixedly arranged on the workbench 1;

[0065] The rotating member 202 is rotatably arranged on the base 201;

[0066] The pin shaft 203. Both the base 201 and the rotating member 202 are provided with pin holes, and the pin shaft 203 is used to fix the base 201 and the rotating member 202.

[0067] In this technical solution, the base 201 is fixed on the workbench 1. The left and right side surfaces of the base 201 are provided with through pin holes. The rotating member 202 is rotatably arranged on the base 201. The rotating member 202 is provided with another pin hole at the same height corresponding to the pin hole on the base 201. The pin shaft 203 is a cylindrical rod-shaped member with one end expanded. During use, the packing material is wound around the outside of the rotating member 202. Then, after the packing material passes around the first tensioning component 4, the sliding member 6, and the second tensioning component 5 in sequence, the other end or the corresponding position of the packing material is wound around the rotating member 202 of the second fixing component 3. Finally, the rotating member 202 is rotated to tension the packing material, and the pin shaft 203 is simultaneously passed through the pin holes of the base 201 and the rotating member 202 to relatively fix the rotating member 202, completing the rough fixing of the two fixing components.

[0068] In some technical solutions, the position of the rotating member 202 where the packing material is snap-connected in the middle is set as an arc-shaped concave surface.

[0069] In this embodiment, the rotating member 202 is provided with a card slot for snap-connecting the packing material.

[0070] In this technical solution, a strip-shaped or cross-shaped card slot extending downward is provided on the top surface of the rotating member 202. When winding the packaging material, the packaging material can be wound around both the card slot and the outside of the rotating member 202 at the same time, so as to improve the fixing force of the fixing component on the packaging material in the form of increasing friction.

[0071] In some technical solutions, the structure of the second fixing component 3 is the same as that of the first fixing component 2.

During use, the first lead screw 401 is rotated through the handle 403 to adjust the front and rear positions of the first guiding member 402, so as to tension the packaging material, which is convenient for the subsequent driving mechanism 7 to drive the pressure sensor 8 and the sliding member 6 to tension the packaging material again for strength detection.

[0077] In some technical solutions, the structure of the second tensioning component 5 is the same as that of the first tensioning component 4.

[0084] In some technical solutions, the connecting component 703 is a coupling. In other technical solutions, the connecting component 703 is a reduction gear set.

[0085] In still other technical solutions, the rotating member 202, the first lead screw 401, the first guiding member 402, the second lead screw 702 and the pressure sensor 8 are arranged in the same plane.
