Abstract

The utility model relates to a button connecting board and board, pole and pole, board and pole and other articles, which is a mechanical structural part and can be easily loaded, unloaded and used, belonging to a mechanical engineering component. The utility model comprises a button body and a connection column, and is characterized in that the connection column is fixed at the article needed to be connected; a plurality of button holes matched with the connection column are arranged at the button body; each button hole comprises a tight hole and a loose hole which are intersected; the tight hole centerline and the loose hole centerline of the same button hole are parallel and equidistant with the button body axes. The utility model is novel in structure and original in function, and has the advantages that different connection results can be realized by designing the button body sizes, arranging the button holes differently and matching with different connection column places at the article which needs to be connected; the utility model is particularly suitable for occasions which needs usually loading and unloading, such as exhibition boards and frames, engineering construction, packing and transportation, toys and teaching aids, decoration furniture and other occasions.

Description

A kind of commentaries on classics button

Technical field the utility model relates to the commentaries on classics button of a kind of connecting plate and article such as plate, bar and bar, plate and bar, is a kind of not only easily the installation but also quick detachable, easy to use mechanical structured member, belongs to the mechanical engineering part.

In the present mechanical engineering of background technique, often needing, the Placement of the article of dismounting mainly is to use bolt.Seek a kind of can place of bolt, do not need setting tool, both had the same intensity of bolt fastener, stability of structure, installing/dismounting method easily all is the probing direction of society research always again.Particularly in some occasion, for example interim Display Rack is too low with the work efficiency of bolt; And some occasion more because structure itself or others do not accomplish with bolton at all, so must find other the method that is fastenedly connected.Yet according to existing patent documentation and market survey, we find that ripe product seldom.

Analyze its reason, just be that bolt fastener has intrinsic intensity, stability and easily adorns readily removablely, all to reach technical requirements aspect three be a very difficult thing and other linkage structure will and easily be adorned readily removable this in intensity, stability.The big portion of existing substitute products has realized a certain function, or has realized two functions of wherein certain, and the function of aspect is left in the basket or takes alternate manner to solve and make operation very inconvenient in addition.

Summary of the invention the utility model just is being based on the defective of existing product, fill a hole in the market, the advantage of comprehensive existing product, the mechanical structured member of article such as a kind of connecting plate and plate, bar and bar, plate and bar has been proposed, being called changes button, by button (5) with connect post (1) and forms (consulting Fig. 1), it is characterized in that Lian Zhu (1) is fixed on the article (2) of needs connection, have on the button (5) and buttonhole (6) that company's post (1) matches.Be easy installation and removal, each buttonhole (6) is intersected with porosity (4) by tieholen (3) to be formed, and the center line of the tieholen (3) of same buttonhole (6) is parallel and equidistant with the axis (7) of button (5) with the center line of porosity (4).Tieholen (3) and the porosity (4) of different buttonholes (6) are being on the circumference at center with axis (7), with tieholen (3), porosity (4), tieholen (3), porosity (4) ... the same sequence arrangement.Lian Zhu (1) can easily pass the porosity (4) of corresponding buttonhole (6), rotates button (5) Lian Zhu (1) is relayed to the corresponding tieholen (3) from porosity (4), and form drive fit with tieholen (3).

The utility model is actually the function that the matching relationship that forms by the buttonhole (6) on the company's post (1) on the article (2) and the button (5) is realized attachment.Thereby the cross surface mutually of the center line that require to connect post (1) and article of living in (2) is vertical relation, and Lian Zhu (1) is fixed on the edge of article (2).According to the different needs of relations such as the quantity of article (2), position, size, connect the buttonhole (6) that post (1) matches with each and on button (5), can be distributed on one or more circumferences, the quantity of the buttonhole on the different circumferences (6) is also decided because of need.

The utility model is used very, and simple principle has satisfied very actual demand of mechanical industry.

Description of drawings Fig. 1 is the structure principle chart of the utility model typical case embodiment, and Fig. 2 is the erection drawing of the utility model typical case embodiment.

Embodiment further specifies structural principle of the present utility model and using method below in conjunction with accompanying drawing.

This embodiment is the application design of carrying out according to the splicing characteristics of plate and plate.On the edge of needs splicing article (2), be fixed with a pair of post (1) (consulting Fig. 1) that connects respectively.The button (5) supporting with connecting post (1) is a slim cylindrical body, axis (7) promptly is cylindrical center line, by tieholen (3) and porosity (4) intersect be " calabash shape " 4 buttonholes (6) on the same circumference of button (5), the center line of the tieholen (3) of each buttonhole (6) and the center line of corresponding porosity (4) are also on the same circumference of button (5), and with tieholen (3), porosity (4), tieholen (3), porosity (4) ... same sequence arrange.Lian Zhu (1) is the drive fit relation with tieholen (3), and is easy to pass porosity (4).During assembling, two article (2) butt joint is got up, make company's post (1) on it press the positional alignment of buttonhole (6), porosity (4) presses down button (5) facing to connecting post (1), rotate button (5), utilize the elasticity of button (5) and company's post (1), Lian Zhu (1) is entered in the tieholen (3) promptly install (consulting Fig. 2).When dismounting, from tieholen (3), produce Lian Zhu (1) in the other direction and get final product.

From using method of the present utility model as can be seen, like very much bolt, installation and removal are all very convenient, and Lian Zhu (1) is equivalent to screw, and button (5) is equivalent to nut.If but connect with bolt, handy 4 covers also must be used instrument, and work efficiency is much lower.In the structure of complexity connected, efficient was much poorer especially.Making material of the present utility model is engineering plastics or metal, alloy etc., and this is the same with general bolt, and the intensity of plate and plate joint is enough.Utilize the elasticity of button (5) and company's post (1), Lian Zhu (1) and tieholen (3) have been realized drive fit, guarantee the stability after install plate and plate joint.

The utility model novel structure, function is original, the size of button (5) design and the different permutation and combination of buttonhole (6) cooperate the design that needs attachment (2) upper linking rod (1) position, can produce different connection effects, be particularly suitable for the place needs that normal dress often unloads, panel Display Rack for example, engineering construction, packed and transported, the toy teaching aid, finishing furniture or the like.
