Abstract

The invention provides a dustproof air bag used between furniture and a wall, and relates to the field of dust prevention. In order to reduce dust accumulated in a gap between the furniture and the wall, the technical scheme is as follows: the dustproof air bag used between the furniture and the wall comprises an air bag body and a plurality of rods, wherein a hole is formed in a side surface of the air bag body; an air bag material on the outer side of the hole is attached to the inner side of a hard cylinder, threads are arranged on the outer side of the cylinder, a nut can seal an end opening of the cylinder through a sealing washer, and an inflating hole is formed in the center of the nut; the rods are inserted into the air bag body from the end opening of the cylinder, threads are arranged at two ends of each rod, and the rods are in threaded connection by nuts; the rods are made of plastic materials; and two ends of each rod are filleted. The dustproof air bag used between the furniture and the wall has the beneficial effects that the air bag body is soft relatively, so that good seal can be realized; the rods are made of the plastic materials and can be shaped to fit the shapes of outlines of edges of the furniture; two ends of each rod are filleted, so that end surfaces of the rods are prevented from piercing the air bag body; and the threads are fully distributed on the outer side of each rod, and therefore, the rods can be cut until the total lengths of the rods are equal to the length of the gap of the furniture.

Description

A kind of use is in furniture and dust-proof air bag between the walls

Technical field

Patent of the present invention is related to dust-proof field, particularly reduces furniture and piles up dust with gap between the walls.

Background technology

Realize dust-proof, existing technology is exactly to be covered above it using dustcloth, but due to general dustcloth ratio Relatively soft, by action of gravity, dustcloth cannot be placed on above furniture and gap between the walls.Dustcloth is for the side of furniture Face, furniture and gap between the walls are capable of suspension type and block, and the dust that similar curtain blocks outside window gets in, but It is that slim and graceful dustproof sheet can be blown afloat by mild wind, substantially reduces its dust-proof effect.If blocking furniture and wall using hard material Although hard material is easy to fixed placement, because wall is not smooth surface, hard material cannot be realized no in gap between wall Sew up tactile, its sealing property is poor, also affect its dust-proof effect.

Content of the invention

Pile up dust for reducing furniture and gap between the walls, present invention design is a kind of to be used in furniture between the walls Dust-proof air bag.

The present invention realizes goal of the invention and the technical scheme is that a kind of use in furniture and anti-dust and gas between the walls Capsule, including an air bag and plurality of rods, is characterized in that: there is a hole side of air bag, and the air bag material outside hole sticks to one , there is screw thread the inner side of individual hard cylinder outside cylinder, a nut can pass through the port of seal washer sealed cylindrical, nut Center has one to inflate hole；Plurality of rods inserts the inside of air bag from cylinder port, and there is screw thread at the two ends of bar, passes through between bar and bar Threaded screw links；Bar is plasticity material, the two ends rounding of bar.

The outside of a wherein bar is covered with screw thread.Or, the outside of all bars is all covered with screw thread.Seal washer and air bag Hole is structure as a whole, and seal washer is located at the port in the hole of air bag, and seal washer is soft material.Bar is the ferrum of diameter 2-3mm Silk.

Beneficial effects of the present invention: air bag is soft, the deformation that air bag can pass through balloon surface after flatulence is tight Contact furniture and the pit of gap between the walls and filling wall surface or furniture surface, realize good sealing, have Effect stops dust from entering furniture and gap between the walls；Bar is plasticity material, can be shaped to family's marginate wheel profile Shape, that is to say, that bar can be distributed in the edge (being in the middle of furniture and gap between the walls) of furniture, can support outer The air bag of side, inflates slightly greater than one atmospheric pressure it becomes possible to ensure that air bag can tympanites be realized to furniture and wall in air bag Gap sealing between wall；The two ends rounding of bar, so that bar is contacted with air bag inner wall smooth, it is to avoid the end face of bar exposes gas Capsule；The outside of a wherein bar is covered with screw thread, or, the outside of all bars is covered with screw thread, as such, it is possible to according to furniture edge with The total length in gap between the walls, carries out cutting to the length of bar, meets different furniture gap lengths (contour edge length) no With requirement, be then threaded connection, (furniture leans on the total length in the length that after making cutting, all bars link together and gap The length of the profile of nearly wall edge) equal.

Specific embodiment

A kind of use, in furniture and dust-proof air bag between the walls, including an air bag 1 and plurality of rods 2, is characterized in that: gas There is a hole side (can in the side of air bag wherein one end, or the side in air bag other positions) of capsule 1, outside hole Air bag material adhesion (adhered to by glue, or melting adhesion) a hard cylinder 3 inner side (i.e. outside air bag with Possesses air-tightness that is to say, that air tight) between inside cylinder；There is screw thread 4, a nut 5 being capable of sealed cylindrical outside cylinder Port, there is seal washer at the inside bottom edge of such as nut, and seal washer is in close contact with cylinder end mouth, this be a kind of often The sealing means seen, the center of nut (end face) has one to inflate hole 6(also known as valve inside), hole is inflated by this and connects and inflate dress Put realization air bag is inflated；The port in the hole of air bag thickeies can serve as seal washer, that is, the hole of seal washer and air bag It is structure as a whole, because the material in the hole of air bag and air bag is all soft, the seal washer energy of the port in pneumatopyle and hole Enough (extruding diminishes) passes through cylinder, makes air bag washer contacts cylinder port, then by nut interior side contacts and compress realization sealing, Seal washer is located at the port in the hole of air bag, and seal washer is soft material (or being same material with air bag)；Plurality of rods 2 Insert the inside of air bag from cylinder port, there is screw thread at the two ends of bar, is linked by threaded screw between bar and bar, the bar after connection If long, can be bent according to the height of furniture and width etc., make the air bag outside bar can be after flatulence The EDGE CONTACT furniture of furniture (i.e. filling furniture and gap between the walls) between the walls, because soft (I of air bag Conventional air bag be all soft material, this is common knowledge), so air bag can be by the deformation of balloon surface after flatulence It is in close contact furniture and gap between the walls and the pit of filling wall surface or furniture surface.Bar is plasticity material Matter, plasticity material is to refer to bend (not rupturing) molding it is usually desirable to bar can be entered by we by the strength of handss Row bending, the iron wire of such as a diameter of 2-3mm.The purpose of the two ends rounding of bar is so that bar is contacted with air bag inner wall smooth, keeps away The end face exempting from bar exposes air bag.

The outside of a wherein bar 2 is covered with screw thread 4；Or, the outside of all bars 2 is covered with screw thread 4.So, we are permissible According to the total length at furniture edge and gap between the walls, cutting is carried out to the length of bar, is then threaded connection, makes cutting The length that all bars link together afterwards is equal with the total length in gap.For avoiding the end contact air bag inwall after cutting, cut out The cutting end of the bar cut will be connected to screw cap end, does not have the other end (rounding, smoother) of cutting can contact air bag Inner side.
