Abstract
The utility model relates to a structural member. The utility model is provide with a self tapping preformed hole, the basic shape of the preformed hole is in the shape of a cylinder hole, and the circumference of the cylinder-shaped hole is axially provided with 2-20 grooves. When the utility model is used, the thread hole can be tappedby the screw of the common thread, and the connection or the position adjustment of the relevant components are realized. The utility model is a basic invention in the mechanical field of the connection or the position adjustment of the small-sized components or the miniature components.
Description
The utility model relates to a kind of structural member, and this structural member can be used as link, also can be used as the adjustment piece of component by holding position.
Be used to connect or adjust the structural member of position, common a kind of form is to make screw in advance in its joint, and then screws the screw that is used to connect or adjust relevant component position.Because of machining internal thread technology is complicated, the event cost is higher.Be equal to or less than the hole of 9.5mm for nominal diameter, the tapping screw of available corresponding size carries out the connection of relevant parts, though self-locking performance was better when tapping screw was connected with corresponding construction spare, use tapping screw not possess the function that realizes adjusting the component position.
The purpose of this utility model is, provide a kind of be suitable for plain screw, cost is lower, when using self-locking performance better, be suitable for connecting usefulness or not only be suitable for connecting with but also be suitable for adjusting the structural member that relevant component position is used with self tapping preformed hole.
The technological scheme that realizes the utility model purpose is (referring to Fig. 1), this structural member has preformed hole (1), the basic shape of preformed hole (1) is a cylindrical hole, is provided with 2～20 grooves (2) on circumference vertically, and the nominal diameter of preformed hole (1) is for being equal to or less than 9.5 millimeters.Because the preformed hole of this structural member is provided with groove, so the screw with regular screw threads can be screwed in preformed hole, is fixed in the preformed hole from the tapping screw thread.
Consider when screw is screwed in preformed hole, structural member stressed more even, groove (2) five equilibrium that is provided with vertically on the circumference is located on the circumference, groove (2) be shaped as rectangle groove, curve bath or fan groove.
Above-mentioned preformed hole (1) is through hole or blind hole.When preformed hole (1) when being blind hole, can realize relevant linkage function; When preformed hole (1) when being through hole, both can realize linkage function, also can realize adjusting the function of position.
Above-mentioned groove (2) has 2～5, and the nominal diameter of preformed hole (1) is 1～5 millimeter.
The used material of said structure spare is engineering plastics or the hardness structural metallic material soft than steel.
Above-mentioned engineering plastics are POM, PPS, PC or ABS engineering plastics, and described structural metallic material is cast aluminium, casting zinc or allumen.
The utlity model has positive effect: (1) this structural member only needs the screw with regular screw threads in use, can realize the function of self tapping, and screw is after on the structural member, and its self-lock force is bigger than tapping screw.When using the screw of common fine thread, it is big that self-lock force is then also wanted.(2) when preformed hole is blind hole, this structural member has the function that connects relevant component; When preformed hole was through hole, the function of the relevant component of the existing connection of this structural member also had the function of the position of adjusting relevant component.That is, can pass through rotary screw, its afterbody is advanced or retreat and reach the function of adjusting relevant component position, this is that tapping screw is not available; When the screw that uses fine thread is adjusted, adjust more accurate.(3) the utility model is the basic innovation and creation that small-sized or miniature component connect or the position is adjusted in the mechanical field, significant, because of the cost of relevant common processes is reduced, so have very real economic implications for industry such as electrical products and instrument product industries.
