Description

Bolt and nut pick-up unit

The utility model relates to and a kind ofly comes the pick-up unit of sorting according to the article size, the device that particularly a kind of mechanical means is measured.

In science and technology flourishing day by day today, people are in life, production, study ... or the like in the environment, dispose various device, utensil, and these equipment, utensil are for making things convenient for its folding dress and maintenance, extensively adopt dismountable structural shape, connect between the member of these demountable devices, utensil, modal being threaded is as combination of screw bolt and nut etc.

At present, the screw bolt and nut of supplying on the market mostly is a standard component, the supplier has the dimensions that meets various needs, when the user dismantled maintenance of equipment, utensil, bolt, nut as needs are changed or substitute is incomplete went market purchasing to satisfy the demands; But, in the ordinary course of things, especially in places such as life, study, demander can not all have the measurement apparatus of bolt, nut, as measures the slide calliper rule or the vernier scale of its external diameter, measures the thread profile gauge of its pitch, tooth form etc., at this moment, demander is directly accurately to recognize the required dimensions of purchasing bolt or nut, and the person of purchasing is as the judgement of Drawing upon subjectivity, and then regular meeting is owing to purchasing to such an extent that do not meet the bolt of required specification or nut and can't use and produce puzzlement; And on existing market, sellers provide screw measuring tool for the buyer, then can make its business operation increase added burden, therefore the measurer of relevant screw thread normally can be provided for client, though, be supplied with bolt, the nut of complete all size on the market, to generally not purchasing the person, still may make mistakes and of no avail, form user's inconvenience and trouble.

The purpose of this utility model is that a kind of bolt and nut pick-up unit will be provided, it can allow the user easy, learn the specification of required bolt back nut exactly, and then conveniently select and buy required bolt or nut.

Utility model is achieved in that bolt and nut pick-up unit include a plate-like body, on body, be spaced and run through the hole that is provided with a plurality of diameters that vary in size, on the entity plate face, each hole one avris respectively correspondence be provided with a size indication district; In each hole of body, wear bolt respectively with the bore hole size correspondence, one end of this bolt is to be formed with a bolt head, class's cylinder that the bolt head extension is provided with supports and is combined on the periphery of hole, bolt is provided with a standard thread post in the extension of class's cylinder one side, this standard thread post is stretched in the body apertures hole outward, bolt is provided with a standard screw at the bolt head place, different size standard thread post or standard screw on the bolt of different size can be used to detect corresponding specifications of nuts or bolt, and obtain corresponding reading in the size indication district.

The standard threaded post is identical with standard screw specification on each bolt, each bolt is sealed a nut, and body two lateral borders are arranged with flange and groove, and body can collude to be established and be seated on the support body, support body includes body frame bar and subframe bar, and body is provided with magnet piece and is provided with scale on two plate faces.

The utility model utilizes standard thread post and the standard screw that has on the bolt that is provided with on the body, the nut that can directly take to need replace for general user or bolt correspondence are revolved and are established reference standards threaded post and standard screw, detection obtains the standard value of its coupling, and observe the reading in size indication district on the pairing body of this standard value simultaneously, this reading promptly indicates the specification of the required screw bolt and nut of buyer, not only accurate but also clearly allow the user buy required screw bolt and nut easily by this size Selection, the utmost point is suitable for common people's detecting operation, has bigger practical value.
