Abstract

The invention provides a roller bolt which comprises a bolt body. One end of the bolt body is designed for being capable of installing an shaft pin and a roller (or a rolling ball, a bearing, a roller for assembling the bearing and the like); a rectangular internal groove is processed at the bottom of the shank of bolt based on a center line; a shaft (pin) hole is punched at an appropriate position along the center line of the internal groove; the roller (rolling elements such as the rolling ball, the bearing and the like) is arranged on a shaft (pin), and the shaft (pin) is embedded into the shaft (pin) hole in a transition fit manner. The other end of the bolt body is a nut which can be tightened and loosened with a wrench, a screwdriver and other tools, so that the nut can lift up and down in a threaded hole matched with the nut and drive a base plate of a rack of an associated instrument and equipment to move, lift up and down and fix; and by adopting angular marks carved on the bolt body and a threaded hole body (on the base plate) matched with the bolt body, the roller bolt can roll at 360 degrees.

Description

Roller bolt

1, technical field

The invention belongs to mechanical device

2, background technique

Bolt, as connecting, fixing (standard) part is widely used in science and technology, production, processing and test etc. on numerous occasions and machinery and the instrument and apparatus, but function dullness, in most of use occasions, make and to fix as the object (as test-bed or casing) that connects, fix and can not roll with bolt.

Roller (rolling elements such as spin, bearing) can play the effect that object is rolled, but it can only be fixed on the bottom of base plate with limiting to, can only play single, passive rolling action, and, when the object of roller support need be fixed on the floor, it has just become burden, must pull down to clear away the bottom surface and could carry out.

" roller bolt " is the two creationary combination, and the roller that can only be fixed on the base plate has been arranged on the bolt, makes it to become to keep the two advantage, abandons the novel product of both sides' shortcoming and limitation.

" roller bolt " is used for object (as test-bed or casing), and object (as test-bed or casing) can be possessed simultaneously can rolling, lifting and fixable function.

3, summary of the invention

For achieving the above object, the technological scheme that is adopted is: in body of bolt bottom, a roller (rolling elements such as spin, bearing) by axle (or pin) serial connection is set creatively, the size of its coupling shaft and roller will be limited in the interior pitch line of the body of bolt; Hexagonal, four directions or inside groove etc. can be processed into can be the easily afterburning structural feature of rotating of instruments such as spanner or screwdriver in body of bolt top; Body of bolt end face will carve clearly reticule.

Body of bolt bottom is as the criterion with center line, processes a rectangular inside groove, gets axle (pin) hole along inside groove center line correct position, and roller (rolling elements such as spin, bearing) is assemblied on the axle (pin), and axle (pin) imbeds in axle (pin) hole by transition fit.

4, description of drawings

As shown in Figure 1, the 1. body of bolt; 2. roller; 3. spool (or pin); 4. locknut.

The casing of installation four " roller bolts " or test-bed are as shown in Figure 2.

Fig. 1 is the section of structure that comprises the body of bolt, axle (or pin), wheel and locknut.

Fig. 2 installs the casing of four " roller bolts " or the sectional view of test-bed.

5, embodiment

As shown in Figure 2, four " roller bolts " are tightened to respectively in four tapped holes of casing or test-bed base plate,, can make the base plate lifting according to the number of turns of tightening; Tighten locknut, can roll by the direction of demarcating; Back out " roller bolt ", can be fixing on the spot with pressing plate; As the internal thread body is provided with (or embedding) in the floor, then can directly be rolled to " roller bolt " on four corresponding tapped holes, tighten " roller bolt " and locknut, need not just realize fixing easily by any outer plate.

Claims

1. roller bolt comprises, pivot pin, roller (or the roller of spin, bearing, running in bearings etc.) and gland nut, engraves angle index on the body of bolt and the screw thread hole body (base plate) that matches;

Body of bolt bottom is as the criterion with center line, processes a rectangular inside groove, gets axle (pin) hole along inside groove center line correct position, and (rolling elements such as spin, bearing are assemblied on the axle (pin) roller, and axle (pin) imbeds in axle (pin) hole by transition fit.

By tighten loose bolts make instrument and equipment stand base plate can rolling, lifting, fixing;

3. the angle index that engraves on the screw thread hole body (base plate) that utilizes the body of bolt and match can be realized the rolling of roller bolt on 360 degree.
