Abstract
Description
Technical Field
[0001] The utility model belongs to the field of central air-conditioning unit equipment, in particular to a novel fixing piece of an inspection panel. Background Art
[0002] Since air conditioning terminal units typically contain components such as filters, surface cooling coils, humidifiers, and fan motors, these components require regular cleaning, maintenance, inspection, and replacement. Therefore, most air conditioning terminal units require access ports for disassembly and inspection. At the same time, to ensure that unit performance parameters such as cooling and heating capacity, air volume, and efficiency are not affected, the access panel fixings must have a certain structural strength and sealing. Therefore, it is very important to design a highly stable and sealed access panel fixing structure.
[0003] The market currently uses a butterfly bolt + pressure plate + rivet nut structure to secure air conditioner access panels. While this existing access panel fixing structure maintains a good seal, it is only suitable when the fixing surface and the fixed surface are on the same horizontal plane. If the fixing surface and the fixed surface are not on the same horizontal plane, the fastening screw will be exposed, reducing the contact surface, making the fixation unstable and the appearance unsightly. Furthermore, this fixing structure is only suitable for air conditioner panel structures that can be riveted, and cannot be used when the installation space or panel thickness of the air conditioner panel structure is limited. Utility Model Content
[0004] In view of this, the present invention aims to provide a novel fixing member for an access panel to solve at least one technical problem in the background technology.
[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:
[0006] A new type of fixing part for an inspection panel, comprising a fixing base, a fastening pressing block, and a hand-tightening bolt;
[0007] The fastening block is provided with a through hole through which a hand-tightening bolt can pass; the hand-tightening bolt passes through the through hole of the fastening block, and the end of the fastening block is mounted on the fixed base;
[0008] The fixed base is installed on the unit to be repaired, and the repair plate is arranged at the bottom of the fastening pressing block.
[0009] Furthermore, the fixed base includes a mounting plate, a mounting column, and a rivet nut; the mounting column is arranged in the middle of the mounting plate, and the rivet nut is arranged on the mounting column.
[0010] Furthermore, mounting holes are provided on both sides of the mounting plate.
[0011] Further, the hand-tightened bolt includes a handle and a threaded rod;
[0012] The handle is arranged at the end of the threaded rod, and the other end of the threaded rod is installed on the fastening pressing block.
[0013] Furthermore, the fastening pressing block includes a connecting ring, a connecting plate, and a pressing plate;
[0014] The connecting ring and the pressing plate are arranged on both sides of the connecting plate, and the through hole is arranged on the connecting ring.
[0015] Furthermore, the connecting ring and the pressing plate are arranged in parallel, the cross section is trapezoidal, and the vertical distance between the pressing plate and the fixed base is the thickness of the inspection plate.
[0016] Compared with the prior art, the new type of fixing member for the access panel described in the present invention has the following advantages:
[0017] 1. The fixing base of the access panel fixing device of this application is fixed to the box panel of the air-conditioning terminal unit by screws. It does not limit the installation space / plate thickness of the air-conditioning box panel structure, nor does it limit the need to rivet the panel, and has a wide range of applications.
[0018] 2. The fastening block of the access panel fixing device of this application is trapezoidal and triangular with the fixing surface. It is suitable for situations where the fixing surface and the fixed surface are not on the same horizontal plane. There will be no situation where the fastening screw is exposed and the fixation is not firm. The fixation is stable and the appearance is beautiful.
[0019] 3. The structural strength of this application is high. The fastening pressure block designed for the inspection panel fixing is flat in contact with the inspection panel. Compared with the previous pressure plate with a hollow bottom, the contact area with the inspection panel is increased, and it is triangular with the fixing surface, which has higher structural strength.
[0020] 4. The access panel fixings of this application can be directly installed on the air-conditioning box panel / frame bar using screws, without the need for riveting on the panel, making installation convenient. BRIEF DESCRIPTION OF THE DRAWINGS
