A vent filter panel

Abstract

This utility model discloses a vent filter plate, including an inner lining support frame fixedly connected to the inner cavity of the vent by bolts. A support frame is slidably connected to the inner cavity of the inner lining support frame. The inner cavity of the support frame is filled with activated carbon filler. A positioning structure is provided in the inner cavity of the inner lining support frame. The positioning structure includes two positioning semi-circular grooves on the left and right sides of the inner cavity of the inner lining support frame. Two circular grooves are provided on both the left and right sides of the support frame. A support short tube is fixedly connected to the inner cavity of the circular grooves. This utility model allows the support frame to be pushed backward, causing a ball bearing to be squeezed into the inner cavity of the support short tube. Then, under the rebound force of the spring, the ball bearing returns to its original position. This allows the support frame to be installed in the inner cavity of the inner lining support frame through the cooperation of the positioning semi-circular grooves and the ball bearing, thus achieving the purpose of allowing the inner lining support frame to be installed or removed from the inner cavity of the vent more quickly.

Technical Field

[0001] This utility model belongs to the field of ventilation technology, and in particular relates to a ventilation outlet filter plate. Background Technology

[0002] Ventilation openings are important structures used for air exchange and circulation. They are metal or composite pipes used in ventilation and air conditioning projects in industrial and civil buildings. Their function is to allow air circulation and reduce the concentration of harmful gases.

[0003] Ventilation vent filter plates can intercept harmful substances such as dust and pollen in the air and improve the quality of incoming air. In order to facilitate the replacement of the filter plates at the ventilation vents, a ventilation vent filter plate has been designed. This structure, through the cooperation of the inner lining support frame and the positioning structure, can make the connection between the support frame and the inner lining support frame quicker, so that the inner lining support frame can be installed or removed from the inner cavity of the ventilation vent more quickly.

[0022] In the following description, embodiments of the ventilation filter plate of this utility model will be described with reference to the accompanying drawings. Example 1

[0023] Figure 1-4This invention illustrates a ventilation filter plate according to an embodiment of the present invention, comprising: an inner lining support frame 2 fixedly connected to the inner cavity of a ventilation opening 1 by bolts; a support frame 3 slidably connected to the inner cavity of the inner lining support frame 2; the inner cavity of the support frame 3 being filled with activated carbon filler 4; a positioning structure 5 provided in the inner cavity of the inner lining support frame 2; the positioning structure 5 including two positioning semi-circular grooves 51 opened on the left and right sides of the inner cavity of the inner lining support frame 2; two circular grooves 52 opened on the left and right sides of the support frame 3; a support short tube 53 fixedly connected to the inner cavity of the circular grooves 52; and a slidably connected support short tube 53 to the inner cavity of the support short tube 53. A spring 55 is welded between the positioning ring 54 and the inner cavity of the circular groove 52. A ball 56 is rolledly connected to the inner cavity of the positioning ring 54. The surface of the ball 56 is rolledly connected to the inner cavity of the inner lining support frame 2. The surface of the ball 56 is rolledly connected to the inner cavity of the positioning semi-circular groove 51. A limiting fixing frame 6 is welded to the rear side of the inner lining support frame 2. By setting the limiting fixing frame 6, the extreme position of the support frame 3 sliding backward during the sliding process of the inner cavity of the inner lining support frame 2 can be limited, which can prevent the support frame 3 from slipping out of the inner cavity of the inner lining support frame 2. Example 2

[0024] Figure 1-4 This invention illustrates a ventilation outlet filter plate according to an embodiment of the present invention, comprising: an inner lining support frame 2 fixedly connected to the inner cavity of a ventilation outlet 1 by bolts; a support frame 3 slidably connected to the inner cavity of the inner lining support frame 2; the inner cavity of the support frame 3 being filled with activated carbon filler 4; a positioning structure 5 provided in the inner cavity of the inner lining support frame 2; the positioning structure 5 including two positioning semi-circular grooves 51 opened on the left and right sides of the inner cavity of the inner lining support frame 2; two circular grooves 52 opened on the left and right sides of the support frame 3; a support short tube 53 fixedly connected to the inner cavity of the circular grooves 52; and the inner cavity of the support short tube 53 being... A limiting ring 54 is slidably connected to the cavity. A spring 55 is welded between the limiting ring 54 and the inner cavity of the circular groove 52. A ball bearing 56 is slidably connected to the inner cavity of the limiting ring 54. A support limiting block 7 is fixedly connected to the inner cavity of the vent 1. The support limiting block 7 is located on the rear side of the limiting fixing frame 6. Two leverage plates 8 are welded to the front side of the support frame 3. By setting the leverage plates 8, the operator can obtain leverage points between the operator and the surface of the support frame 3 during the installation or disassembly of the support frame 3, making the installation or disassembly of the support frame 3 more convenient.

[0025] Working principle: When using this utility model, the user fixes the support limiting block 7 to the inner cavity of the vent 1, thereby positioning the inner lining support frame 2 at the required position. Then, the inner lining support frame 2 is fixed to the inner cavity of the vent 1 with bolts. Subsequently, the user pushes the lever plate 8 to drive the support frame 3 to slide within the inner cavity of the vent 1, and the support frame 3 slides into the inner cavity of the inner lining support frame 2. At this time, the ball bearing 56, supported by the limiting ring 54 and the spring 55, contacts the inner lining support frame 2. The inner wall of the support frame 3 is then pushed backward to squeeze the ball 56 into the inner cavity of the support short tube 53. When the rear side of the support frame 3 contacts the limiting fixing frame 6, the position of the ball 56 is consistent with the positioning semi-circular groove 51. Under the rebound force of the spring 55, the ball 56 is reset, thereby positioning the support frame 3 in the inner cavity of the inner lining support frame 2 through the cooperation of the positioning semi-circular groove 51 and the ball 56, thus completing the installation of the support frame 3. This allows the inner lining support frame 2 to be installed or removed from the inner cavity of the vent more quickly.

[0026] In summary: This vent filter plate, by pushing the support frame 3 backward, causes the ball bearing 56 to be squeezed into the inner cavity of the support short tube 53, and then the ball bearing 56 is reset under the rebound force of the spring 55. Thus, the support frame 3 is installed in the inner cavity of the inner lining support frame 2 through the cooperation of the positioning semi-circular groove 51 and the ball bearing 56, thereby achieving the purpose of allowing the inner lining support frame 2 to be installed or removed from the inner cavity of the vent more quickly.
