Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology for cleanroom color steel plates, specifically a ventilation duct for cleanroom color steel plates that is easy to connect. Background Technology

[0002] Cleanroom color steel plate, also known as cleanroom plate or clean panel, is a building material specially designed for high-requirement environments such as clean rooms and dust-free workshops. It is composed of color steel plate and stainless steel plate as surface material, and rock wool, glass wool, paper honeycomb, ceramic aluminum plate, and glass magnesium plate as core material.

[0003] For example, a non-powered exhaust hood with publication number "CN119373286A" improves the exhaust efficiency by adding a fan mechanism that rotates with the hood body or the hood support mechanism to the hood support structure. However, this non-powered exhaust hood is only fixed with multiple bolts during installation. Over time, the vibration generated by the rotation of the hood can easily cause the bolts to loosen, resulting in a displacement of the hood and affecting the ventilation effect. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the ventilator is installed, it is fixed by multiple bolts. After long-term use, the bolts are easily loosened, causing the ventilator to shift and affecting the ventilation effect. Therefore, this utility model proposes a cleanroom color steel plate ventilation duct that is easy to connect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A ventilation duct made of cleanroom color steel plate is designed for easy connection. It includes a cleanroom color steel plate and a first threaded hole. Multiple first threaded holes are machined on both sides of the cleanroom color steel plate. An installation structure is provided inside the cleanroom color steel plate. The installation structure includes an installation plate. A positioning block is fixedly connected to the bottom of the installation plate. The outer wall of the positioning block engages with a rubber pad. The outer wall of the rubber pad is fixedly connected to a positioning groove.

[0007] Preferably, the positioning groove is machined on the inner wall of the cleanroom color steel plate, and multiple third threaded holes are machined on both sides of the positioning groove.

[0008] Preferably, the inner walls of both the third threaded hole and the second threaded hole are threaded to the bolts, and the second threaded hole is machined on both sides of the mounting plate.

[0009] Preferably, a non-powered wind cap is fixedly connected to the upper end of the mounting plate.

[0010] Preferably, the positioning block, the mounting plate, and the inner wall of the cleanroom color steel plate are all machined with through holes.

[0011] This utility model proposes a ventilation duct for easy connection of cleanroom color steel plates. Its advantages are as follows: Through the cooperation of the cleanroom color steel plate and the installation structure, the operator inserts the positioning block into the positioning groove. At this time, the multiple second threaded holes on the positioning block align with the multiple third threaded holes on the cleanroom color steel plate. Then, the operator rotates multiple bolts, causing the bolt ends to be screwed into the second and third threaded holes respectively, thereby fixing the mounting plate onto the cleanroom color steel plate. Subsequently, the non-powered ventilator can be installed onto the cleanroom color steel plate. The cooperation of the positioning groove and the positioning block secures the mounting plate, and the rubber pad increases friction, making the fixed non-powered ventilator more stable and minimizing its swaying, thus reducing the impact of swaying on the ventilation effect.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6In this embodiment, a ventilation duct made of easily connectable cleanroom color steel plate includes a cleanroom color steel plate 1 and first threaded holes 2. The cleanroom color steel plate 1 (the figure is only for specific structural display, and the specific size of the cleanroom color steel plate 1 is subject to actual processing requirements) has multiple first threaded holes 2 processed on both sides. The cleanroom color steel plate 1 is provided with an installation structure 4. The installation structure 4 includes an installation plate 401. A positioning block 402 is fixedly connected to the bottom of the installation plate 401. The outer wall of the positioning block 402 engages with a rubber pad 403. The rubber pad can play a sealing role. The outer wall of the rubber pad 403 is fixedly connected to the positioning groove 407.

[0021] Positioning groove 407 is machined on the inner wall of the cleanroom color steel plate 1. Multiple third threaded holes 406 are machined on both sides of the positioning groove 407. The inner walls of the third threaded holes 406 and the second threaded holes 405 are threadedly connected to bolts 404. The second threaded holes 405 are machined on both sides of the mounting plate 401. A non-powered wind cap 3 is fixedly connected to the upper end of the mounting plate 401. The positioning block 402, the mounting plate 401 and the inner wall of the cleanroom color steel plate 1 are all machined with through holes 5. The cleanroom color steel plate 1 is made of color steel plate and stainless steel plate as surface material, and rock wool, glass wool, paper honeycomb, ceramic aluminum plate, glass magnesium plate and other materials as core material.

[0022] Working principle:

[0023] When installing cleanroom color steel plate ventilation ducts:

[0024] Operators connect the purification color steel plate (1 Purification color steel plate 1 is composed of color steel plate and stainless steel plate as surface material, and rock wool, glass wool, paper honeycomb, ceramic aluminum plate, glass magnesium plate and other materials as core material as composite material. Among them, rock wool, glass wool and other core materials have a certain filtering and adsorption effect, which can purify impurities in the air) to the wall through the first threaded holes 2 on both sides and the expansion bolts.

[0025] The operator inserts the positioning block 401 into the positioning groove 407. At this time, the multiple second threaded holes 405 on the positioning block 401 and the multiple third threaded holes 406 on the cleanroom color steel plate 1 are aligned. Then, the operator rotates the multiple bolts 404 so that the ends of the bolts 404 are screwed into the second threaded holes 405 and the third threaded holes 406 respectively, thereby fixing the mounting plate 401 on the cleanroom color steel plate 1. Then, the non-powered vent 3 can be installed on the cleanroom color steel plate 1. Through the cooperation of the positioning groove 407 and the positioning block 401, the mounting plate 401 can be locked in place, and the rubber pad 403 can increase the friction, making the fixed non-powered vent 3 more stable, which can minimize the shaking of the non-powered vent 3 and reduce the impact of shaking on the ventilation effect.

[0026] When the wind blows, the non-powered vent 3 will automatically rotate according to the wind force, thereby driving the airflow in the room, expelling the exhaust gas and heat from the room through the through hole 5, and introducing fresh air from the outside.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
