Abstract
The utility model relates to an adjusting bolt, which is characterized in that an original cast steel bolt hook is changed into a stainless steel bolt hook, one end of the stainless steel bolt hook is provided with a bolt, and the other end thereof is provided with a hook; two stainless steel bolt hooks are rotated into an adjusting screw rack through screw holes at the two ends of the adjusting screw rack, and the length of the two bolt hooks is exactly equal to the length of the adjusting screw rack when the screw threads of bolt heads are fully screwed in; and cotter pins pass through the cotter pin holes of the bolts and are blocked by the adjusting screw rack, so that the stainless steel bolt hooks can not rotate at random. The surface of the adjusting bolt adopts chemical passivation antirust and corrosion-resistant treatment.
Description
Technical field
The utility model relates to a kind of industrial attachment, particularly relates to the adjustable bolt of using on a kind of electric railway locomotive railway contact line.
Technical background
Original product adopts Steel Castings, and intensity is low, and is perishable, regulates gib head and easily get loose under tired vibration condition.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned shortcoming, provides a kind of result of use good adjustable bolt.
This product adopts the manufacturing of metal paattern forging process, and gib head adopts stainless steel, and has increased the reinforced rib setting, increase the stop pin setting, improved the mechanical property of product, withstanding corrosion, overcome the caducous shortcoming of connection gib head, replaced the backguy of the former employing of electric railway " V " font.
Changing the former employing Steel Castings of bolt gib head is the manufacturing of metal paattern forging process, and gib head adopts the stainless steel bolt gib head, and its shape is that an end is a bolt, and the other end is a gib head; Its stack-mounted method is with two bolt gib head ends, rotates into relatively from the tapped bore of adjusting screw rod frame two ends, and when the bolt cap screw thread revolves when most, the length of two bolts is to adjust the length of screw rod frame just; The length of promptly adjusting the screw rod frame is the twice of bolt.Pass from the cotter-pin hold of bolt with spring cotter and to be adjusted the screw rod frame and to block, the pinning bolt must not rotate arbitrarily.
Take out spring cotter, the rotation adjustable bolt can be adjusted the degree of tightness that connects cable wire between two gib heads, and is last, and body adopts hot galvanizing method passivation anti-rust treatment.
Description of drawings
Accompanying drawing is the adjustable bolt structural representation
Wherein: 1, stainless steel bolt gib head; 1.1, bolt; 2, bolt gib head;
3, adjust the screw rod frame: 4, spring cotter.
The specific embodiment
This product adopts the manufacturing of metal paattern forging process, and gib head adopts stainless steel, and has increased the reinforced rib setting, increase the stop pin setting, improved the mechanical property of product, withstanding corrosion, overcome the caducous shortcoming of connection gib head, replaced the vee shape backguy of the former employing of electric railway.
Changing the former employing Steel Castings of bolt gib head is the manufacturing of metal paattern forging process, and gib head adopts stainless steel bolt gib head 1, and its shape is that an end is a bolt 1.1, and the other end is a gib head 2; Its stack-mounted method is with two bolt gib head 1.1 ends, rotates into relatively from the tapped bore of adjusting screw rod frame 3 two ends, and when the bolt cap screw thread revolves when most, the length of two bolts is to adjust the length of screw rod frame 3 just; The length of promptly adjusting screw rod frame 3 is the twice of bolt 1.1.Pass from the cotter-pin hold of bolt 1.1 with spring cotter 4 and to be adjusted screw rod frame 3 and to block, pinning bolt 1.1 must not rotate arbitrarily.Body adopts hot galvanizing method passivation anti-rust treatment.
