The utility model is characterized in that the bottom of the contacting board (4) is provided with a plurality of cones (10) which have bit top and small bottom and are inserted into a carpet; the width or diameter of the contacting board (4) is less than the inner diameter of the bearing section (8).

Description

The furniture Self-levelling castor

The utility model belongs to the furniture part field, specifically is a kind of furniture Self-levelling castor.

The furniture Self-levelling castor is the annex of being convenient to move, reduce friction, protect the furniture bottom surface that is contained in furniture such as sofa, chair and ground contacting part position.When producing for the client and furniture be installed, we find that the furniture castor that can buy on the present market and the contact plate on ground are that contact-making surface is one whole, furniture is installed the back and is slided easily, if and be installed in when being equipped with carpet indoor, whole block contact-making surface is easy to weigh wounded or damages senior carpet by pressure, can inscribe irreplaceable vestige on carpet.

The purpose of this utility model is in order to overcome the deficiencies in the prior art, for people provide a kind of furniture Self-levelling castor, this Self-levelling castor is installed in the furniture bottom can make furniture that the difficult slip in back is installed, do not weigh and damage by pressure carpet wounded, remove behind the furniture and be difficult for leaving a trace on the carpet, carpet is maintained the original state substantially.

The purpose of this utility model is finished by following technical proposals.

Furniture Self-levelling castor of the present utility model: by contiguous block (1), be connected section (2), cover (3), contact plate (4) is connected in sequence from top to bottom, have connecting hole (5) on the tabular contiguous block (1), the projection (6) that is connected section (2) its top is stuck in or is threadedly connected in the center connecting hole of contiguous block (1), cover (3) top is linkage section cylindraceous (7), the bottom is supporting section cylindraceous (8), supporting section (8) is greater than linkage section (7), the two arc-shaped transition, linkage section is provided with internal thread in (7), cooperate with the external screw thread of the section of linking (2), tabular contact plate (4) bottom is laid with the cone (10) in a plurality of insertion carpets, the screw-internal thread fit of the external screw thread of the columned projection in contact plate (4) top (9) and the section of linking (2) lower end, the width of contact plate (4) or diameter are less than the internal diameter of cylindric supporting section (8).

Contiguous block described in the such scheme (1), linking section (2), cover (3) can two or three directly be processed into an integral body arbitrarily.

The utility model has overcome the deficiencies in the prior art, for people provide a kind of furniture Self-levelling castor, this Self-levelling castor is installed in the furniture bottom can make furniture that the difficult slip in back is installed, and does not weigh and damage by pressure carpet wounded, remove behind the furniture and be difficult for leaving a trace on the carpet, carpet is maintained the original state substantially.

Further describe the utility model below by embodiment, but the utility model is not limited only to described embodiment.

Accompanying drawing 1 is a structural representation of the present utility model.

Among the figure: 1, contiguous block; 2, be connected section; 3, cover; 4, contact plate; 5, connecting hole; 6, projection; 7, linkage section; 8, supporting section; 9, projection; 10, cone.

As shown in the figure: furniture of the present utility model is connected in sequence by contiguous block (1), linking section (2), a cover (3), contact plate (4) from top to bottom with Self-levelling castor, describes the shape and the interconnected relationship thereof of each element below setting out for ease of understanding from top to bottom:

The shape of contiguous block (1) does not have strict demand, can be flat boards such as square, circular, triangle, have connecting hole (5) on the contiguous block (1) so that be connected with the bottom of furniture, the projection (6) that is connected section (2) its top is stuck in or is threadedly connected in the center connecting hole of contiguous block (1), and the two is linked together.As shown in the figure, contiguous block (1) and linking section (2) also can be machined directly to an integral body.

The shape such as the bell jar of cover (3), its top is linkage section cylindraceous (7), the bottom is supporting section cylindraceous (8), and supporting section (8) is greater than linkage section (7), the two arc-shaped transition, linkage section is provided with internal thread in (7), cooperating with the external screw thread of the section of linking (2), promptly be connected the outside of section (2), also can only be that its outside, bottom has screw thread, be connected section (2) and insert in the linkage section (7) on cover (3) top, the two is linked together by threaded engagement.As shown in the figure, contiguous block (1) and linking section (2) also can be machined directly to an integral body.

Contact plate (4) is circular or the plate of the dull and stereotyped or band camber line of square or other shape etc., contact plate (4) bottom is laid with the cone (10) in a plurality of insertion carpets, cone (10) is up big and down small to be convenient to insert in the carpet, the external screw thread of the cylindric projection (9) on contact plate (4) top and the screw-internal thread fit of the lower end of the section of linking (2) combine the two.

The width of contact plate (4) or diameter are less than the internal diameter of cylindric supporting section (8), when no carpet, contact plate (4) can be revolved and rise in supporting section (8), lean on this moment the supporting section (8) of cover (3) to contact with ground and play a supportive role, the thickness of supporting section of the present invention (8) is greater than the thickness of mask support section in the prior art.

In the such scheme, the annexation of each element and shape can design arbitrarily, projection (9) as contact plate (4) can directly link to each other with the linkage section (7) of cover (3), is connected section (2) and can utilizes the internal thread and the external screw thread of cover (3) to cooperate promptly the section of linking (2) to be placed on the linkage section (7) or the like.

In the such scheme, except that contact plate (4), contiguous block (1), linking section (2), cover (3) can two or three directly be processed into an integral body arbitrarily.At this moment, contiguous block (1), the shape that is connected section (2), cover (3) and annexation are not limited to above-mentioned example and can design arbitrarily.The utility model is mainly invented and is that contact plate (4) bottom is laid with the design of the cone (10) in a plurality of insertion carpets, and the structure of other element, shape, annexation can design arbitrarily.
