Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention and the accompanying drawings are combined together to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
Referring to fig. 1 to 3, an embodiment of the present invention provides a simple air return opening, which includes a frame 1, a screen 2 and a filter screen 3; the frame 1 is fixedly coated on four sides, and the left inner side and the right inner side of the frame 1 are respectively provided with a clamping hole 5 for mounting the screen plate 2; through holes for air return are arranged on the surface of the screen plate 2, protruding clamping tongues 4 are arranged on the left side edge and the right side edge of the screen plate 2 corresponding to the clamping holes 5, and the clamping tongues 4 are clamped in the clamping holes 5 to fix the screen plate 2 in the frame 1; the filter screen 3 is fixed on the screen plate 2.
The net plate 2 has two preferred embodiments according to the structure and working principle of the latch 4. In the present embodiment, as a first preferable solution, the latch 4 is in a sheet shape and is integrally formed with the left and right sides of the net plate 2, and the net plate 2 is made of an elastic material.
The structure is simplest, the processing is easy, and the forming only needs to be carried out through plates. When the screen plate 2 is arranged on the frame 1, the clamping tongue 4 is inserted into the clamping hole 5 by about 1-2 mm. When the screen plate 2 needs to be disassembled, the screen plate 2 only needs to be hooked and pulled downwards, and the clamping tongue 4 can be separated from the clamping hole 5 under slight elastic deformation under stress, so that the screen plate falls off from the frame 1. The screen plate 2 and the screen 3 can then be cleaned at will.
The installation process is reversed, and the mesh plate 2 is aligned with the frame 1 and pressed upwards. The clamping tongue 4 is elastically deformed by the acting force of the frame 1 until the clamping tongue is clamped into the clamping hole 5.
As shown in detail in fig. 2, as a further preferred embodiment, the frame further comprises clamping plates 6, wherein the clamping plates 6 are fixedly arranged on the front and rear inner sides of the frame 1 and form elastic clamps with downward openings together with the front and rear inner sides of the frame 1; the front side and the rear side of the screen plate 2 are provided with longitudinal folded edges 7 extending upwards, and the longitudinal folded edges 7 are provided with convex parts 8 matched with the clamping plates 6, so that the convex parts 8 are limited by the clamping plates 6 when the longitudinal folded edges 7 are inserted into the elastic clamps.
If the net plate 2 is fixed only by the clamping tongues 4 and the clamping holes 5 on the left side and the right side, the stability is lower undoubtedly, and the net plate is easy to shake under the action of breeze in the air exhaust process. The clamping action of the clamping plate 6 can assist in maintaining stability.
With particular reference to fig. 3, for the specific structure of the frame 1, it is preferable that the frame 1 is composed of longitudinal plates 10 at both longitudinal sides and transverse plates 9 at both transverse sides; the longitudinal plates 10 and the transverse plates 9 are fixedly connected through rivets; the outer side of the longitudinal plate 10 is provided with a longitudinal installation edge for hoisting; and a transverse mounting edge for hoisting is arranged on the outer side of the transverse plate 9.
The plate is formed, so that the structure is simple, and the assembly and the processing are easy. The hoisting of the frame 1 is completed through the action between the longitudinal installation edge and the transverse installation edge and the ceiling keel. The installation principle is equivalent to the action principle between the common ceiling and the keel. The concrete structures of the longitudinal mounting edge and the transverse mounting edge can be adjusted according to the structural form of the keel, for example, the keel is of an exposed frame overlapping type, and the longitudinal mounting edge and the transverse mounting edge can be turned outwards to form an overlapping edge which is overlapped on the keel; if the keel adopts a hidden frame clamping type, the longitudinal installation edge and the transverse installation edge can be vertically extended and elastically clamped by the keel.
Example two
The only difference between this embodiment and the first embodiment is the specific structure of the latch 4.
Referring to fig. 4, in particular, in the present embodiment, preferably, the left and right sides of the net plate 2 are provided with transverse flanges extending upward, and the flanges are provided with guide holes; the clamping tongues 4 are arranged at two ends of the horizontal rod 11, the horizontal rod 11 is transversely inserted in the guide hole, and a spring is arranged between the horizontal rod 11 and the transverse folded edge.
The horizontal bar 11 can slide in a biased manner in the transverse direction of the guide hole to one side, in the process, the latch tongue 4 on one side can be extended longer, and the latch tongue on the other side can be retracted. According to the principle, the clamping tongue 4 on one side can be clamped into the clamping hole 5 firstly, the clamping tongue 4 on the other side is squeezed manually to be contracted, and the clamping tongue 4 is automatically clamped into the clamping hole 5 on the other side after the screen plate 2 is laid flat.
For the convenience of disassembly, it is preferable that the middle part of the horizontal rod 11 is provided with a toggle part 12 protruding from the surface of the horizontal rod 11 in the radial direction. When the screen plate 2 needs to be detached, a small tool such as a screwdriver can extend into the through hole of the screen plate 2 and pry the poking part 12, so that the clamping tongue 4 on one side is contracted, and the screen plate 2 is further separated.
EXAMPLE III
The latch 4 of the present embodiment adopts a third structure.
Referring to fig. 5, in the present embodiment, preferably, the left and right sides of the net plate 2 are provided with horizontal folding edges extending upward, and the horizontal folding edges are provided with mounting grooves 13; the clamping tongue 4 is arranged on an elastic member 14, the bottom end of the elastic member 14 is elastically opened and can be detachably tensioned in the mounting groove 13, the top end of the elastic member 14 is closed and provided with a limiting hook 15, each group of clamping holes 5 are arranged in pairs, the limiting hook 15 is arranged between each group of clamping holes 5 in a hooking mode, the clamping tongue 4 is arranged below the limiting hook 15, and the clamping tongue 4 is elastically opened and clamped in the clamping holes 5.
Before installation, the two ends of the bottom of the elastic member 14 firstly penetrate through the clamping holes 5 from top to bottom, so that the limiting hook 15 is hooked between the two clamping holes 5, and then the bottom end of the elastic member 14 is manually pinched to be contracted, so that the elastic member can be tensioned in the installation groove 13 of the screen plate 2. At this time, the net plate 2 is already hung on the frame 1 through the elastic member 14, but is not flush with the frame 1, but protrudes below the frame 1. At the moment, the screen plate 2 is forcibly pushed upwards to force the clamping tongue 4 of the elastic member 14 to contract and elastically expand after passing through the clamping hole 5 to limit the screen plate 2. The limiting hook 15 is always hooked between the clamping holes 5 for limiting, so that the screen plate 2 is prevented from accidentally falling.
When the screen plate 2 needs to be detached, the screen plate 2 is pulled down forcibly and separated from the screen plate 2 by manually pinching the elastic member 14.
Other technical features of the second and third embodiments can be adopted in the scheme of the first embodiment, and are not described herein again.
The utility model provides a pair of simple and easy return air inlet, simple structure, low cost assembles and processes easily. The screen plate 2 can be easily assembled and disassembled without disassembling the frame 1, thereby cleaning the filter screen 3 and the screen plate 2. Can be applied to different suspended ceiling keel systems.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
