[0032] In the conventional dust sampling process, the fixing mode of the sampling hose is often relatively simple, and generally uses ordinary clips or binding tapes for fixing. The conventional fixing device often lacks flexibility, and the versatility of the conventional fixing device is poor for sampling hoses of different diameters and materials. A fixing device can only be applicable to a specific specification of hose, and when different types of sampling hoses need to be replaced, the fixing device may need to be searched for or adjusted again, which brings inconvenience to actual work. In view of the above technical problems, the utility model provides a double-sided nylon self-locking fixing device for dust individual monitoring sampling hose, which can be applied to sampling hoses of different diameters and materials, and is convenient for workers to install the sampling hose. The technical scheme of the utility model will be described in detail below in combination with specific examples.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , the utility model relates to a double-sided nylon self-locking fixing device for dust individual monitoring sampling hose, which comprises a mounting seat 1 and a locking assembly 2, the locking assembly 2 comprises a lock hole 21, a pressing plate 22 and a drawstring 23, wherein the lock hole 21 is arranged on the mounting seat 1, the pressing plate 22 is arranged in the lock hole 21, and the pressing plate 22 and the lock hole 21 have a locking spacing 24 for the drawstring 23 to pass through.

[0034] One end of the cable 23 is connected to one side of the mounting base 1, and the cable 23 is arranged correspondingly to the pressing plate 22. The cable 23 is uniformly and spacedly provided with a plurality of limiting teeth 231, the limiting teeth 231 include a vertical surface 232 and an inclined surface 233, the inclined surface 233 is used to guide the pressing plate 22 to pass the vertical surface 232 in a forward direction, and the vertical surface 232 is used to limit the pressing plate 22 to pass the inclined surface 233 in a reverse direction. The locking assembly 2 is provided with two, which are arranged in a stacked manner.

[0035] Exemplarily, when the user installs the sampling hose, the device can be used to quickly and stably install the sampling hose on the collar. In the installation process, a common collar clamp needs to be applied to be clamped and installed at a suitable position, then the cable 23 on one of the locking assemblies 2 is inserted through the through hole reserved on the collar clamp, then the cable 23 is inserted into the corresponding lock hole 21. In the process of insertion, the limiting teeth 231 on the cable 23 guide the pressing plate 22. When the cable 23 is inserted and gradually tightened, the inclined surface 233 on the limiting teeth 231 faces the pressing plate 22. At this time, the inclined surface 233 guides the pressing plate 22 to pass the vertical surface 232 on the current limiting tooth 231 until the cable 23 tightens the collar clamp. After the cable 23 is loosened, the pressing plate 22 is inserted into the gap formed between the two limiting teeth 231 at the current position. The pre-tightening force of the tightened cable 23 also forms a reverse tension on the cable 23. At this time, the pressing plate 22 is in contact with the adjacent vertical surface 232 and limits the reverse movement of the cable 23. The self-locking effect of the limiting teeth 231 and the pressing plate 22 realizes the effect of fixedly installing the collar clamp. Since the locking assembly 2 is provided with two, the other locking assembly 2 can be used to bundle and install the sampling tube.

[0036] Through the arrangement of the structure, the device can be applied to sampling hoses with different diameters and materials, and it is convenient for the staff to install the sampling hose.

[0037] In this embodiment, more preferably, in order to stagger the overall installation operation, the extension directions of the two cables 23 are arranged in opposite directions. Specifically, the corresponding limiting teeth 231 of the two cables 23 are arranged in opposite directions. For details, please refer to Figure 1 and Figure 2 .

[0038] For details, please refer to Figure 4 . In an embodiment, the specific structure of the mounting base 1 is further refined. The mounting base 1 includes a fixed part 11, a top plate 12 and a bottom plate 13. The fixed part 11 is arranged in an H shape, the top plate 12 closes the top of the fixed part 11 to form one of the lock holes 21, and the bottom plate 13 closes the bottom of the fixed part 11 to form the other lock hole 21. The top plate 12 and the bottom plate 13 are respectively located opposite to the corresponding pressing plate 22, and the pressing plate 22 and the top plate 12 and the bottom plate 13 form two locking spacings 24.

[0039] In this embodiment, preferably, one side of the top plate 12 is rotationally connected with the fixing member 11, and the fixing member 11 is provided with the activity assembly 3 for limiting the activity of the top plate 12, so as to fix the top plate 12 to close the top of the fixing member 11.

[0040] In this embodiment, specifically, the activity assembly 3 comprises a rotating shaft 31 and a limiting rod 32.

[0041] The rotating shaft 31 is rotationally connected with the fixing member 11, the bottom surface of the limiting rod 32 is attached to the top surface of the top plate 12, and the top plate 12 is provided with a avoiding hole 121 for installing the rotating shaft 31, which is arranged at the edge of the top plate 12 to allow the limiting rod 32 to be separated from the top plate 12.

[0042] Specifically, when the device is in the installation state, the limiting rod 32 is located on the top surface of the top plate 12, the limiting rod 32 limits and fixes the top plate 12, limits the outward overturning of the top plate 12, so as to ensure that the cable 23 cooperates with the locking distance 24 to realize the binding self-locking installation. When subsequent disassembly is required, the limiting rod 32 is selected to rotate and separate from the top plate 12, at which time the overturning limitation of the top plate 12 is released, thereby realizing the effect of activity adjustment. Through the arrangement of the structure, the device can not only be applied to the installation of sampling hoses with different diameters and materials through the self-locking structure, but also can be easily disassembled by the staff, and has the advantage of high use flexibility.

[0043] In this embodiment, preferably, in order to improve the connection stability between the limiting rod 32 and the top plate 12, the limiting rod 32 and the top plate 12 are arranged in an interference fit.

[0044] The interference fit allows the two to have a higher degree of attachment, a larger static friction force, and improved limiting stability of the limiting rod 32 and the top plate 12, thereby improving the binding installation stability of the device.

[0045] In this embodiment, preferably, the edge of the top plate 12 corresponding to the avoiding hole 121 is provided with a round corner. The arrangement of the round corner can facilitate the rotation of the limiting rod 32 into the upper part of the top plate 12, thereby playing a guiding role.
