[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] Example 1:

[0023] The present application discloses a device for quickly installing and removing samples for a SBI single combustion test. Figure 1 In this embodiment, the SBI single combustion test rapid sample installation and removal device includes a sample vehicle fixing plate 1, a fixing frame telescopic rod 2, an upper sample fixing frame 3, an upper sliding assembly, a lower sample fixing frame 4, and a lower sliding assembly. The top of the sample vehicle fixing plate 1 is mounted on the sample vehicle, and the sample vehicle fixing plate 1 is a rectangular structure. The fixing frame telescopic rod 2 slides through the center of the sample vehicle fixing plate 1, and a telescopic rod hole 11 is formed in the center of the sample vehicle fixing plate 1. The telescopic rod hole 11 cooperates with the fixing frame telescopic rod 2, allowing the fixing frame telescopic rod 2 to slide through the telescopic rod hole 11 and the center of the sample vehicle fixing plate 1.

[0024] At the same time, the center of one side of the upper sample holder 3 is installed on the end of the holder telescopic rod 2 away from the telescopic rod hole 11, and the top of the upper sample holder 3 is installed on the top of the combustion chamber through the upper sliding assembly. By setting the upper sliding assembly, the upper sample holder 3 can slide on the top of the combustion chamber.

[0025] Better, refer to Figure 1 In this embodiment, a telescopic rod operating handle 7 is mounted on the end of the mounting frame telescopic rod 2 away from the upper sample mounting frame 3. The telescopic rod operating handle 7 is located on the side of the sample trolley mounting plate 1 facing away from the upper sample mounting frame 3 to prevent the mounting frame telescopic rod 2 from becoming detached from the sample trolley mounting plate 1. The design of the telescopic rod operating handle 7 conforms to ergonomic principles, provides comfortable operation, and facilitates single-handed operation. Furthermore, a safety lock is provided on the telescopic rod operating handle 7 to ensure safety during operation.

[0026] When the telescopic rod operating handle 7 is pulled, the fixed frame telescopic rod 2 can be driven to slide along the telescopic rod hole 11 of the sample vehicle fixing plate 1, and then the fixed frame telescopic rod 2 drives the upper sample fixing frame 3 to slide closer to one side of the sample vehicle fixing plate 1.

[0027] In addition, the lower sample holder 4 is installed on the bottom of the combustion chamber through a lower sliding assembly. The lower sample holder 4 corresponds to the upper sample holder 3. By setting the lower sliding assembly, the lower sample holder 4 can slide on the bottom of the combustion chamber.

[0028] In addition, mounting grooves are provided on the corresponding sides of the lower sample holder 4 and the upper sample holder 3. The top side of the sample 8 to be tested cooperates with the mounting groove of the upper sample holder 3, and the bottom side of the sample 8 to be tested cooperates with the mounting groove of the lower sample holder 4, so that the sample 8 to be tested is placed between the upper sample holder 3 and the lower sample holder 4 to achieve clamping and installation of the sample 8; at the same time, the sample 8 can also be quickly removed from between the upper sample holder 3 and the lower sample holder 4 through the mounting groove.

[0029] Preferably, the width of the mounting groove is greater than the thickness of the sample 8 , so that samples 8 of different sizes and shapes can be clamped and mounted between the upper sample holder 3 and the lower sample holder 4 , so as to facilitate the reciprocating movement of the sample 8 .

[0030] The structures of the upper sliding assembly and the lower sliding assembly are described in detail below:

[0031] Specifically, refer to Figure 1 In this embodiment, the upper sliding assembly includes two upper rails and an upper rail connector 31. Two upper rails are provided, and the two upper rails are symmetrically mounted on the top of the combustion chamber; two upper rail connectors 31 are provided, and the two upper rail connectors 31 are symmetrically mounted on the top of the upper sample holder 3. The two upper rail connectors 31 respectively cooperate with the two upper rails, so that the upper sample holder 3 can slide back and forth on the two upper rails through the two upper rail connectors 31.

[0032] Specifically, refer to Figure 1 In this embodiment, the lower sliding assembly includes two lower rails and a lower rail connector 41. Two lower rails are provided, and the two lower rails are symmetrically mounted at the bottom of the combustion chamber. Two lower rail connectors 41 are provided, and the two lower rail connectors 41 are symmetrically mounted at the bottom of the lower sample holder 4. The two lower rail connectors 41 respectively cooperate with the two lower rails, allowing the lower sample holder 4 to slide back and forth on the two lower rails through the two lower rail connectors 41.

[0033] When the sample 8 is clamped and installed in the installation groove between the upper sample fixing frame 3 and the lower sample fixing frame 4, by pulling the telescopic rod operating handle 7, the upper sample fixing frame 3 and the lower sample fixing frame 4 can simultaneously drive the sample 8 to move back and forth under the traction action of the fixing frame telescopic rod 2; in this way, by setting the cooperation between the upper slide rail and the upper slide rail connector 31, and by the cooperation between the lower rail and the lower rail connector 41, it can be ensured that the sample 8 is stable and reliable during movement.

[0034] In addition, refer to Figure 1 In this embodiment, spring mounting rods 5 are symmetrically installed on the side of the upper sample holder 3 facing the sample cart fixing plate 1, and the two spring mounting rods 5 are perpendicular to the upper sample holder 3; and mounting rod holes 12 are symmetrically opened on the sample cart fixing plate 1, and the two mounting rod holes 12 respectively cooperate with the two spring mounting rods 5; when the telescopic rod operating handle 7 is pulled, the two spring mounting rods 5 of the upper sample holder 3 move along the mounting rod holes 12 toward the sample cart fixing plate 1, thereby achieving an effective limiting and guiding effect.

[0035] At the same time, compression springs 6 are sleeved on the two spring mounting rods 5, and the two ends of the compression springs 6 are respectively abutted between one side of the sample trolley fixing plate 1 and one side of the upper sample fixing frame 3; when the telescopic rod operating handle 7 is pulled, the two spring mounting rods 5 move along the mounting rod holes 12 toward the sample trolley fixing plate 1, which can compress and deform the compression springs 6; when the pulling force applied to the telescopic rod operating handle 7 is released, the upper sample fixing frame 3 drives the two spring mounting rods 5 to reset and move under the elastic restoring action of the compression springs 6.

[0036] In addition, refer to Figure 1 and Figure 2 In this embodiment, a pressing groove 21 is provided on the rod body at one end of the telescopic rod 2 of the fixing frame, and a pressing mechanical lock 22 is slidably installed in the groove of the pressing groove 21. The side surface of the pressing mechanical lock 22 is a triangular structure; and a pressing spring 23 is installed between the pressing mechanical lock 22 and the bottom of the pressing groove 21; the pressing spring 23 can push the top of the pressing mechanical lock 22 out of the pressing groove 21 under normal conditions; when the pressing mechanical lock 22 is subjected to downward pressure, the pressing spring 23 can be elastically compressed, so that the pressing mechanical lock 22 can rotate completely into the groove of the pressing groove 21.

[0037] Preferably, limit sliders 24 are symmetrically installed on both sides of the pressing mechanical lock 22, and limit slots 25 are opened on the groove walls on both sides of the pressing groove 21. The two limit slots 25 cooperate with the two limit sliders 24 respectively, so that the two limit sliders 24 on the pressing mechanical lock 22 slide in the two limit slots 25, thereby effectively limiting and guiding the pressing mechanical lock 22, thereby preventing the entire pressing mechanical lock 22 from escaping from the outside of the pressing groove 21.

[0038] When the telescopic rod operating handle 7 is pulled, the fixed frame telescopic rod 2 moves along the telescopic rod hole 11, and the side wall of the telescopic rod hole 11 squeezes the inclined edge of the pressing mechanical lock 22, so that the pressing mechanical lock 22 rotates and retracts into the pressing groove 21 under the action of the pressing spring 23.

[0039] When the pressing mechanical lock 22 retracted into the pressing groove 21 passes through the telescopic rod hole 11, the pressing mechanical lock 22 loses the pressure of the side wall of the telescopic rod hole 11. Under the elastic restoring action of the pressing spring 23, the top of the pressing mechanical lock 22 extends out of the pressing groove 21. At this time, the pulling force on the telescopic rod operating handle 7 is released, so that the pressing mechanical lock 22 is automatically locked on one side of the sample cart fixing plate 1, thereby making the upper sample fixing frame 3 close to the sample cart fixing plate 1, so that the tested sample 8 can be quickly unloaded.

[0040] When the new sample 8 is reinstalled in the installation groove between the upper sample holder 3 and the lower sample holder 4, the inclined surface of the pressing mechanical lock 22 is pressed again, so that the pressing mechanical lock 22 is retracted into the pressing groove 21 to unlock the holder telescopic rod 2. Then, under the restoring and rebounding action of the compression spring 6, the upper sample holder 3 and the lower sample holder 4 simultaneously drive the new sample 8 to reset and move, so that the new sample 8 can be tested again.

[0041] Therefore, by utilizing this device, in actual applications, it is possible to complete sample unloading in 1 minute (excluding cleaning time) and installation in 1 minute, thereby providing a more convenient and efficient testing method for fire protection product testing, thereby effectively improving the accuracy and reliability of fire protection product testing and contributing to the development of the fire safety field.

[0042] Preferably, an anti-slip groove is provided on the inclined surface of the push-type mechanical lock 22. The anti-slip groove cooperates with the installer's fingers to facilitate the installer's ability to quickly lock and unlock the sample 8, thereby improving assembly and disassembly efficiency. Alternatively, the installer can use a tool that cooperates with the anti-slip groove to press the push-type mechanical lock 22, which can also achieve the same effect while also preventing the installer's hands from being injured, thereby achieving an effective protective effect.

[0043] Therefore, by providing a structure in which the sample trolley fixing plate 1, the telescopic rod opening 11, the fixing frame telescopic rod 2, the upper sample fixing frame 3, the upper sliding assembly, the lower sample fixing frame 4, the lower sliding assembly, the spring mounting rod 5, the compression spring 6, the pressing mechanical lock 22, and the pressing spring 23 cooperate with each other, the sample 8 can be quickly clamped, installed, and removed. At the same time, the device has the advantages of easy installation, quick removal, and convenient operation, thereby significantly improving test efficiency and reducing operational difficulty. In addition, the device has a compact design, strong durability, and is easy to maintain and service.

[0044] The implementation principle of the SBI single-unit combustion test quick installation and removal sample device in the embodiment of the present application is: when the telescopic rod operating handle 7 is pulled outward, the fixed frame telescopic rod 2 drives the upper sample fixing frame 3 and the lower sample fixing frame 4 to move toward the sample vehicle fixing plate 1 at the same time; when the side wall of the telescopic rod hole 11 squeezes the inclined edge of the pressing mechanical lock 22, the pressing mechanical lock 22 rotates and retracts into the pressing groove 21 under the action of the pressing spring 23.

[0045] When the pressing mechanical lock 22 retracted into the pressing groove 21 passes through the telescopic rod hole 11, the pressing mechanical lock 22 loses the pressure of the side wall of the telescopic rod hole 11. Under the elastic restoring action of the pressing spring 23, the top of the pressing mechanical lock 22 extends out of the pressing groove 21. At this time, the pulling force on the telescopic rod operating handle 7 is released, so that the pressing mechanical lock 22 is automatically locked on one side of the sample cart fixing plate 1, thereby positioning the upper sample fixing rack 3 close to the sample cart fixing plate 1 to achieve rapid unloading of the tested sample 8.

[0046] Then, the new sample 8 is reinstalled in the installation groove between the upper sample holder 3 and the lower sample holder 4. Then, the inclined surface of the pressing mechanical lock 22 is pressed to retract the pressing mechanical lock 22 into the pressing groove 21 to unlock the holder telescopic rod 2. Then, under the restoring and rebounding action of the compression spring 6, the upper sample holder 3 and the lower sample holder 4 simultaneously drive the new sample 8 to reset and move, thereby completing the installation of the new sample 8 for testing.

[0047] Example 2:

[0048] Reference Figure 3 In this embodiment, the difference between Example 2 and Example 1 is that a plurality of positioning components are provided on the side of the upper sample holder 3 and the lower sample holder 4 facing away from the sample vehicle fixing plate 1. The positioning components can simultaneously firmly position the upper and lower sides of samples 8 of different sizes and shapes in the mounting groove.

[0049] Specifically, the following describes the structure of the positioning assembly mounted on the lower sample holder 4 in detail: the positioning assembly comprises a threaded rod 9, a knob block 91, and a positioning block 92. A threaded hole is defined on the side of the lower sample holder 4 facing away from the sample cart mounting plate 1. The threaded rod 9 is threadedly connected to the hole, with one end of the threaded rod 9 extending into the mounting slot. The knob block 91 is mounted on the end of the threaded rod 9 extending out of the mounting slot. The positioning block 92 is mounted on the end of the threaded rod 9 away from the knob block 91.

[0050] By rotating the knob 91, the threaded rod 9 drives the positioning block 92 to press against one side of the sample 8, thereby firmly positioning the sample 8 in the mounting slot, thereby further ensuring that the sample 8 is more stable and reliable when moving. Preferably, the positioning block 92 is a rubber block, which can effectively protect the sample 8.

[0051] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
