Problems solved by technology

[0004] 1. Tighten the pull rope for fixing the goods during work, but during operation, the goods will be displaced due to the vibration of the road surface, causing the pull rope to loosen. The looseness of the pull rope will cause the threaded parts on both sides of the turnbuckle to lose pre-tightening force. Make the turnbuckle and tie rod easy to separate, resulting in irreparable loss
[0005] 2. The thread of the turnbuckle bolt is prone to failure under high tension, especially the failure of the thread matching part

Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0037] Such as figure 1 , 2 As shown, it includes a pull rod 1, an adjustment shell 2, where as Figure 4 As shown, the two ends of the adjustment shell 2 are fixedly installed with a second nut 8 with opposite screw threads, as shown in FIG. figure 1 , 2 , 3, one end of the pull rod 1 has a pull hook, and the outer circular surface of the other end of the pull rod 1 has an external thread, such as figure 1 , 2 As shown, one end of the two pull rods 1 with external threads is mounted on both ends of the adjustment shell 2 through internal and external threads, and is characterized in that: image 3 , 5 As shown, the inside of the adjustment shell 2 is rotatably equip...

Abstract

The invention belongs to the technical field of bolts, and in particular relates to a bolt, which includes a pull rod and an adjusting shell. In the invention, after the pull rope for fixing the goods is tightened, the gear adjusting plate is moved so that one end of the clip bar is stuck on the ratchet The corresponding ring ratchet is stuck inside. At this time, move the adjusting wobble plate so that the adjusting wobble plate drives the adjustment ring to rotate, the adjustment ring drives the ratchet to rotate through the clip, the ratchet drives the adjustment sleeve to rotate, and the adjustment sleeve rotates through the guide block and the guide groove The cooperation drives the two first nuts to rotate, so that the two first nuts will slide towards the side where the lock spring is installed while rotating, and the lock spring is compressed; the pre-tightening force is generated by the compressed lock spring ;Prevent the goods from shifting due to the vibration of the road surface during operation and make the pull rope loose. The looseness of the pull rope will cause the threaded parts on both sides of the turnbuckle bolt to lose pretightening force, making the turnbuckle bolt and the pull rod easy to separate, resulting in irreparable damage. loss.

Description

technical field [0001] The invention belongs to the technical field of bolts, in particular to a bolt. Background technique [0002] The turnbuckle bolt is composed of an adjusting rod with left and right-handed threads, a nut and a pull rod; the tension of the wire rope can be adjusted by using the lead screw to expand and contract. Components can be bundled during component transportation and loosened during installation and correction. [0003] However, the basket bolts have the following problems during use: [0004] 1. Tighten the pull rope for fixing the goods during work, but during operation, the goods will be displaced due to the vibration of the road surface, causing the pull rope to loosen. The looseness of the pull rope will cause the threaded parts on both sides of the turnbuckle to lose pre-tightening force. The turnbuckle bolt and the pull rod are easily separated, causing irreparable losses. [0005] 2. The thread of the turnbuckle bolt is prone to failure...
