Description

Technical Field

[0001] The present utility model relates to a quick installation component for a filter screen of a range hood.

Background Art

[0002] The filter screen of an oil fume extractor is installed on the air inlet to intercept the grease in the oil fume and prevent the grease from entering the air cavity inside the oil fume extractor. Therefore, users need to regularly disassemble the filter screen to avoid blockage of the filter screen affecting the wind force. Currently, a locking tongue is provided on the filter screen in the market, which is stuck on the air inlet through the locking tongue. However, this locking tongue is fixed, and when the user disassembles it, they need to align the locking tongue with the reserved disassembly opening on the air inlet before they can disassemble it. There are still problems with inconvenience in disassembly and assembly.

[0003] Therefore, it is necessary to make further improvements to it.

Content of the Utility Model

[0004] The purpose of the present utility model is to overcome the above problems. We provide a quick installation component for a filter screen of a range hood. The filter screen of the range hood using this quick disassembly component can be quickly disassembled.

[0005] To achieve the above purpose, the present utility model provides a quick installation component for a filter screen of a range hood, including a housing and a movable locking plate. The movable locking plate is arranged inside the housing and can slide back and forth relative to it. A locking tongue extending out of the housing is provided on the front side of the movable locking plate. An avoidance opening for the telescopic movement of the locking tongue is opened on the front side of the housing. Tensile springs are respectively arranged on the left and right sides of the movable locking plate. A first hanging part is arranged at the front side position of the housing. A second hanging part is arranged on the movable locking plate. The two ends of the tensile spring are respectively connected to the first hanging part and the second hanging part. A hand pulling part is arranged on the movable locking plate. An operation opening is opened on the upper end face of the housing corresponding to the hand pulling part.

[0006] In one or more embodiments, a gap is left between the left and right side surfaces of the movable locking plate and the side wall of the housing, and the gap is 1MM - 3MM.

[0007] In one or more embodiments, limiting parts bent inward are arranged on the left and right sides of the housing, and the limiting parts can press the upper end of the movable locking plate to prevent it from tilting up.

[0008] In one or more embodiments, a convex part is arranged on the front side of the housing, and the convex part can abut against the front end of the movable locking plate.

[0009] In one or more embodiments, a structural plate part is arranged between the tensile springs on the left and right sides of the movable locking plate, and the structural plate part is bent forward to form the hand pulling part.

[0010] In one or more embodiments, the housing includes an upper housing and a lower housing. The rear end of the upper housing is connected to the rear end of the lower housing through a connecting portion, and the front end of the upper housing is fixedly connected to the front end of the lower housing by screws or rivets.

[0011] In one or more embodiments, the housing and the movable locking plate are made of stainless steel or aluminum alloy.

[0012] The effect of the present utility model compared with the background technology is that the quick-installation component is used for assembling and using on the smoke machine filter screen. It has a retractable locking tongue. The user retracts the locking tongue by pulling the manual pulling part and then disassembles the smoke machine filter screen; after letting go, the locking tongue extends again under the action of the tension spring. Using this principle, the quick installation and disassembly of the smoke machine filter screen on the air inlet can be realized.

Detailed Embodiments

[0015] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with the embodiments and the drawings. The embodiment is only used to explain the present utility model and does not constitute a limitation on the protection scope of the present utility model.

[0016] Please refer to the attached Figure 1-2 As shown in the figure, the present utility model provides a quick-installation component for a smoke machine filter screen, which includes a housing 1 and a movable locking plate 2. The movable locking plate is arranged inside the housing and can slide back and forth relative to it. A locking tongue 3 that extends out of the housing is provided on the front side of the movable locking plate 2. An avoidance opening 4 for the telescopic movement of the locking tongue is provided on the front side of the housing 1. Tension springs 5 are respectively provided on the left and right sides of the movable locking plate. A first hanging portion 6 is provided at the front side position of the housing, and a second hanging portion 7 is provided on the movable locking plate. The two ends of the tension spring 5 are respectively connected to the first hanging portion and the second hanging portion. A manual pulling part 8 is provided on the movable locking plate 2. An operation opening 9 is provided on the upper end surface of the housing corresponding to the manual pulling part. The user pulls the manual pulling part outside through the operation opening to retract the locking tongue into the housing. At this time, the tension spring is in a stretched and stressed state. When the user lets go, under the elastic force of the tension spring, the locking tongue will extend out of the housing again.

[0017] A gap is left between the left and right side surfaces of the movable locking plate 2 and the side wall of the housing. The gap is 1MM - 3MM, preferably 1MM, 2MM, 2.5MM, 3MM. This gap can not only avoid the frictional force generated by the contact between the movable locking plate and the housing and affect the smoothness of sliding, but also prevent the displacement of the movable locking plate.

[0018] The left and right sides of the housing are provided with inwardly bent limiting portions 10 which can press against the upper end of the movable locking plate 2 to prevent it from tilting. Under normal circumstances, the limiting portions do not contact the movable locking plate.

[0019] The front side of the housing is provided with a protruding portion 11 which can abut against the front end of the movable locking plate 2. The protruding portion can limit the forward distance of the movable locking plate, thereby determining the protruding length of the lock tongue.

[0020] A structural plate portion 12 is provided between the tension springs on the left and right sides of the movable locking plate 2. The structural plate portion is bent forward to form the hand-pulling portion 8. The structural tightness between the bent and formed hand-pulling portion and the movable locking plate is better, and the forming is simple and easy to process.

[0021] The housing 1 includes an upper housing 101 and a lower housing 102. The rear end of the upper housing is connected to the rear end of the lower housing through a connecting portion 103. The front end of the upper housing and the front end of the lower housing are connected and fixed by screws or rivets. The number of connecting portions is two, and they are arranged at intervals left and right.

[0022] The housing 1 and the movable locking plate 2 are made of stainless steel material or aluminum alloy material. Preferably, stainless steel is used, which has the advantages of easy cleaning, waterproof and rust-proof.

[0023] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention should be included in the protection scope recorded in the claims.
