[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses a fire retardant coating thickness measurement auxiliary hole opening tool, referring to Figure 1-Figure 3 In this embodiment, the auxiliary hole opening tool includes a pressing plate 1, an inserting nail 2 and a sleeve 3. The pressing plate 1 is a disc-shaped structure, and the diameter of the pressing plate 1 of the disc-shaped structure is 50 mm. The diameter of the inserting nail 2 is 4 mm, and its length is 160 mm. The top of the inserting nail 2 is firmly installed in the middle of one side of the pressing plate 1 through a fastening mechanism. Through the setting of the fastening mechanism, not only can the inserting nail 2 be firmly installed on one side of the pressing plate 1, but also the inserting nail 2 can be removed from the pressing plate 1, so as to facilitate the replacement of the inserting nail 2.

[0025] At the same time, the length of the sleeve 3 is 100mm, and a channel 31 is opened inside the sleeve 3. The inner diameter of the channel 31 is 5mm. At this time, the wall thickness of the sleeve 3 is 4mm; and the channel 31 cooperates with the insertion nail 2, so that the insertion nail 2 extends out of the sleeve 3 along the channel 31 to be inserted into the interior of the fire retardant coating 5; and by setting a pressing plate 1 on the top of the insertion nail 2, pressure is applied to the pressing plate 1, so that the insertion nail 2 can be inserted into the interior of the fire retardant coating 5 more easily and quickly, until the surface of the steel layer 6 stops applying pressure, so that the fire retardant coating 5 can be opened to facilitate the insertion of the thickness needle into the hole, thereby achieving an effective detection effect on the thickness of the fire retardant coating 5.

[0026] In this way, by setting the structure in which the pressing plate 1, the inserting pin 2 and the sleeve 3 cooperate with each other, not only the problem that the thickness needle is difficult to insert into the coating for detection is solved, thereby avoiding the wear of the thickness needle due to touching the substrate, so as to improve the detection efficiency and reduce the detection cost; but also the accuracy of the detection data can be effectively improved, thereby improving the accuracy of the detection results and the practicality of the device. At the same time, the auxiliary hole opening tool of the present application is easy to make, low cost, and easy to master.

[0027] Better, refer to Figure 1 and Figure 3 In this embodiment, a disc base 4 is fixedly mounted on the outer side wall of the end of the sleeve 3 away from the pressing plate 1. The diameter of the disc base 4 is 30 mm and the thickness is 4 mm. When it is necessary to make a hole in the fireproof coating 5, the disc base 4 is pressed against the surface of the fireproof coating 5, so that the verticality of the insertion nail 2 inserted into the thickness of the fireproof coating 5 can be controlled, so that the insertion nail 2 always remains in a vertical state when inserted into the fireproof coating 5, so that the opened hole remains in a vertical state, thereby effectively ensuring the accuracy of the detection data.

[0028] At the same time, the provision of the disc base 4 can also increase the force-bearing area between the sleeve 3 and the fire-retardant coating 5 , thereby facilitating improving the stability of the sleeve 3 .

[0029] In addition, refer to Figure 4 In this embodiment, the fastening mechanism includes a fastening block 21 and a clamping assembly. The fastening block 21 is mounted on the top of the insertion pin 2; and a fastening groove 11 is provided on one side of the pressing plate 1. The fastening groove 11 and the fastening block 21 are engaged with each other, so that the insertion pin 2 is firmly engaged in the fastening groove 11 through the fastening block 21, thereby facilitating the insertion pin 2 to be firmly mounted on the pressing plate 1.

[0030] At the same time, the clamping assembly is arranged in the groove wall of the fastening groove 11 to effectively reinforce the fastening block 21. Specifically, in the present embodiment, the clamping assembly includes a clamping ball 13 and a spring 14. Among them, a plurality of sliding grooves 12 are provided on the groove walls around the fastening groove 11; a plurality of clamping balls 13 are provided, and the plurality of clamping balls 13 are respectively slidably installed in the sliding grooves 12; a plurality of springs 14 are provided, and one end of the plurality of springs 14 is respectively fixedly connected to the groove wall of the sliding grooves 12, and the other end of the plurality of springs 14 is respectively fixedly connected to one side of the plurality of clamping balls 13; and a plurality of clamping grooves 22 are provided on the outer wall of the fastening block 21, and the plurality of clamping grooves 22 are respectively clamped with the plurality of clamping balls 13.

[0031] When the fastening block 21 on the insertion nail 2 is inserted into the fastening groove 11 of the pressing plate 1, the fastening block 21 on the insertion nail 2 squeezes the card ball 13, so that the card ball 13 squeezes the spring 14, causing the spring 14 to deform and shrink; when the card slot 22 on the fastening block 21 corresponds to the sliding groove 12, the squeezing force on the card ball 13 is canceled, and then the spring 14 elastically resets to push the card ball 13 forward, so that one side of the card ball 13 is snapped into the card slot 22 of the fastening block 21, which can effectively reinforce the fastening block 21, thereby further firmly installing the insertion nail 2 on the pressing plate 1, thereby improving the stability of the insertion nail 2.

[0032] Better, refer to Figure 3 In this embodiment, a plurality of sliding balls 32 are rollingly mounted on the inner side wall of the sleeve 3. The sliding balls 32 are evenly distributed inside the channel 31, and the sliding balls 32 are respectively in contact with the insertion nail 2. By providing the sliding balls 32, the friction generated when the insertion nail 2 and the sleeve 3 are in contact can be reduced, so that the insertion nail 2 can slide out of the sleeve 3 more smoothly along the channel 31; it can also effectively protect and guide the insertion needle, thereby increasing the service life of the insertion nail 2.

[0033] The implementation principle of the fire retardant coating thickness measurement auxiliary hole opening tool in the embodiment of the present application is: when working, the disc base 4 is placed on the surface of the fire retardant coating 5, and held by hand, and then the insertion nail 2 is inserted into the channel 31 of the sleeve 3 until it reaches the surface of the fire retardant coating 5, and then the pressing plate 1 is pressed hard to make the insertion nail 2 inserted into the interior of the fire retardant coating 5 along the channel 31 until the surface of the steel layer 6 is reached. The pressure can be stopped, and then the insertion nail 2 is pulled out, so that a hole can be opened in the fire retardant coating 5, and finally a thickness needle is inserted into the hole to measure the thickness of the fire retardant coating 5.

[0034] The above description is only 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 specification 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.
