Description

Technical Field

[0001] This utility model relates to a heating, ventilation and air conditioning (HVAC) technology, and in particular to a bottom-supported high-efficiency air outlet installation and fixing structure, which is applicable to fields such as chemical, pharmaceutical, and clean factories. Background Technology

[0002] High-efficiency air supply outlets and terminal filtration devices in cleanrooms are key equipment for meeting purification requirements. With the increasing number of cleanroom applications, more and more installation challenges arise due to limited space.

[0003] Existing common high-efficiency air outlet installations require the use of turnbuckles to tighten the high-efficiency air outlet from the top for installation and adjustment. For example, patent publication number CN222256989U describes a high-efficiency air outlet installation structure, which includes an air outlet body and a hanging plate on the air outlet body. The hanging plate suspends the air outlet body from the ceiling via a hanging rod. The hanging plate is movably mounted on the air outlet body via an adjustment component. The adjustment component includes a mounting frame with a movable mounting component. The mounting component has a fine-tuning component that can move along a direction perpendicular to the movement of the mounting component. The hanging plate is raised and lowered on the fine-tuning component.

[0004] These traditional structures require ceiling space greater than the space needed to install the high-efficiency air supply outlet plus the length of the turnbuckle, forcing a reduction in the cleanroom height to increase installation space, or adjustment of the high-efficiency air supply outlet position to ensure installation space, and in some space-constrained cleanrooms, they cannot be used at all. Summary of the Invention

[0005] The purpose of this utility model is to solve the above problems and provide a bottom-supported high-efficiency air outlet installation and fixing structure. It has the characteristics of low installation space, as long as the ceiling space can accommodate the high-efficiency air outlet box, and has a large adjustment capacity.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a bottom-supported high-efficiency air outlet installation and fixing structure, including a high-efficiency air outlet box, characterized in that perforated fixing plates are respectively provided on both sides of the top of the high-efficiency air outlet box, and an upper positioning member is provided in cooperation with the perforated fixing plate. The upper positioning member cooperates with the upper end of the adjusting screw, and a support leg is provided directly below the upper positioning member to cooperate with the lower end of the adjusting screw.

[0007] In the aforementioned bottom-supported high-efficiency air outlet mounting and fixing structure, preferably, the adjusting screw is a double-ended screw structure, with the upper end of the adjusting screw positioned on the upper positioning member by a tightening nut assembly, and the lower end of the adjusting screw positioned on the support leg by a tightening nut assembly.

[0008] In the aforementioned bottom-supported high-efficiency air outlet installation and fixing structure, preferably, the upper positioning component is an L-shaped angle steel structure, the support leg has an arched frame structure, and the lower end of the adjusting screw passes through the top of the arched frame and is positioned by the tightening nut assembly.

[0009] In the aforementioned bottom-supported high-efficiency air outlet mounting and fixing structure, preferably, the height of the support leg is less than the height of the high-efficiency air outlet housing, and the length of the adjusting screw is less than the height of the support leg.

[0010] In the aforementioned bottom-supported high-efficiency air outlet installation and fixing structure, preferably, the support leg is provided with a support base plate, the support base plate is provided with rivet holes, and the support base plate is fixed to the ceiling plate of the high-efficiency air outlet housing installation part by pop rivets.

[0011] In the aforementioned bottom-supported high-efficiency air outlet installation and fixing structure, preferably, the bottom of the high-efficiency air outlet box is the air outlet, and the corresponding air inlet is arranged in the horizontal part of the high-efficiency air outlet box.

[0012] In the aforementioned bottom-supported high-efficiency air outlet installation and fixing structure, preferably, the support base plate of the legs is provided with shock-absorbing rubber pads.

[0013] This technical solution arranges the inlet and outlet of the high-efficiency air outlet box in a mutually perpendicular direction, uses the ceiling panel to support the high-efficiency air outlet box, and transfers the supporting force to the ceiling panel through the perforated fixing plates set on both sides of the top of the box. The supporting force is accomplished by the upper positioning component, adjusting screw, and support legs that cooperate with the perforated fixing plate. The adjusting screw also undertakes the task of height adjustment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by transforming the bottom support structure of the support force, the installation space of the high-efficiency air outlet is greatly reduced, so that the high-efficiency air outlet can be installed as long as it can be placed in the ceiling; it has a large adjustment capability and strong versatility. As long as the support legs are made according to the smallest high-efficiency air outlet, the installation of all specifications of high-efficiency air outlets can be met by selecting an adjustment screw of appropriate length; the structure is simple and the installation and adjustment are convenient.

Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] This embodiment describes a bottom-supported high-efficiency air outlet mounting and fixing structure, such as... Figures 1 to 3 As shown, the high-efficiency air outlet housing 1 is hexagonal in shape, with an air outlet at the bottom and an air inlet on one side perpendicular to the air outlet. Two perforated fixing plates 101 are respectively installed on the top of the high-efficiency air outlet housing 1 and on both sides perpendicular to the air outlet. The perforated fixing plates 101 are vertically positioned, and an upper positioning component 2 is provided to cooperate with them. The upper positioning component 2 is an L-shaped angle steel structure, with its vertical side fixed to the perforated fixing plate 101 using bolts 5, flat washers 6, spring washers 7, and nuts 8. The horizontal side of the upper positioning component 2 cooperates with the upper end of an adjusting screw 9. The adjusting screw 9 is a double-ended screw structure, with its upper end passing through a through hole on the horizontal side of the upper positioning component 2 and then positioned on the upper positioning component 2 by a tightening nut assembly 10 (double nuts).

[0024] A support leg 3 is provided directly below the upper positioning member 2, which cooperates with the lower end of the adjusting screw 9. The lower end of the adjusting screw 9 is positioned on the support leg 3 by the clamping nut group 10 (double nuts). Specifically, the support leg 3 has an arched frame structure, and the lower end of the adjusting screw 9 passes through the top of the arched frame and is then positioned by the clamping nut group 10.

[0025] Furthermore, the height of the support leg 3 is less than the height of the high-efficiency air outlet housing 1, and the length of the adjusting screw 9 is less than the height of the support leg. Therefore, within the existing ceiling height range, the installation of the high-efficiency air outlet housing 1 at different heights can be accommodated by adjusting the adjusting screw 9.

[0026] Furthermore, the outrigger 3 has a channel steel support 302, the top of which is a support top plate 301, and the bottom of which is a support base plate 303. The support base plate 303 has rivet holes, and the support base plate 303 is fixed on-site to the ceiling plate 4 of the high-efficiency air outlet housing 1 using pop rivets 11. Shock-absorbing pads can be laid under the support base plate 303 of the outrigger 3 to reduce vibration.

[0027] Working principle:

[0028] By using a bottom-supporting structure for the high-efficiency air outlet housing 1, its installation space requirements are reduced. Installation can be achieved simply by placing the high-efficiency air outlet housing 1 into the ceiling space. A wide range of adjustments can be made using the support legs 3 and adjusting screws 9. In practical applications, for different specifications and models of high-efficiency air outlet housing 1, the support legs 3 can be manufactured according to the minimum height of the high-efficiency air outlet housing, and then extended bolts 9 of appropriate length can be selected to accommodate the installation of all specifications of high-efficiency air outlet housings.

[0029] The above embodiments are illustrative of the present invention and not intended to limit it. Although the present invention has been described in conjunction with preferred embodiments, it should be understood that the present invention is not limited to the preferred embodiments. Those skilled in the art can make various equivalent modifications and substitutions to the technical solutions of the present invention based on its teachings. Therefore, the scope of the present invention should be defined by the claims, and all such equivalent modifications and substitutions fall within the protection scope of the present invention.
