Description

Technical Field

[0001] The utility model belongs to the technical field of bolts, in particular to a bolt provided with a locking structure. Background Art

[0002] Bolts are a commonly used fastener, usually made of metal, and its structure consists of two parts: a bolt shank and a bolt head. The main function of a bolt is to pass the bolt shank through the holes of two or more parts by rotating the bolt head, and then fix them together with washers or lock nuts to form a tight connection.

[0003] Among them, it was found through searching that the application number is CN202121415690.9, a kind of anti-loosening sealing flange bolt, the anti-loosening sealing flange bolt has a threaded column and a plug-in column with a fixing hole at the corresponding position inside, and a fixing pin is arranged inside the fixing hole, and the fixing pin is threadedly connected with the fixing hole. This arrangement can prevent the rotation of the locking member and prevent the nut from reversing. The bolt is connected to the flange through a double thread structure, which increases the sealing of the connection and improves the stability of the bolt; among them, the shortcomings are as follows:

[0004] When the staff uses this kind of anti-loosening sealing flange bolt to lock the bolt, they rotate the locking piece to make it contact with the flange, and screw the bolt between the fixing hole and the fixing pin set inside the threaded column and the plug-in column to prevent the locking piece from rotating, and at the same time prevent the nut from reversing. However, when the bolt is screwed into the fixing hole and the fixing pin to prevent the locking piece from rotating, since the nut is not locked, it is still easy for the nut to loosen, causing the bolt to loosen, resulting in loose pipe connections and leakage.

[0029] Embodiment 2:

[0030] like Figure 5As shown, in the utility model, a limiting frame B701 is slidably arranged inside the groove 7, and the side of the limiting frame B701 is arranged in an inclined shape, a damping telescopic rod C702 is fixedly installed between the lower part of the limiting frame B701 and the lower part of the inner wall of the mounting groove 102, and a spring is matched with the outer side of the damping telescopic rod C702, a limiting groove A1021 is embedded in the upper part of the inner wall of the mounting groove 102, and the side of the inner wall of the limiting groove A1021 is arranged in an inclined shape, and the upper part of the limiting frame B701 is fitted and slidably arranged on the inner side of the limiting groove A1021, there is another implementation method, in which the limiting frame B701 is slidably arranged inside the groove 7, and the upper part of the limiting frame B701 is arranged in a truncated cone shape, a damping telescopic rod C702 is fixedly installed between the lower part of the limiting frame B701 and the lower part of the inner wall of the mounting groove 102, and the outer side of the damping telescopic rod C702 is matched with A spring is provided, and a limiting groove A1021 is embedded on the upper inner wall of the installation groove 102, and the inner wall of the limiting groove A1021 is set in a truncated cone shape, and the upper limit frame B701 is slidably arranged on the inner side of the limiting groove A1021. When the staff slides a number of bolts 103 into the inner sides of the relative installation grooves 102 respectively, the limiting frame B701 is squeezed to drive the damping telescopic rod C702 and the outer spring to contract, so that the bolt 103 completely slides into the inner sides of the installation groove 102, and the limiting frame B701 approaches the limiting groove A1021. At this time, the damping telescopic rod C702 and the outer spring pop out the limiting frame B701 to slide into the inner side of the limiting groove A1021 to limit the bolt 103, thereby completing the docking between the pipe A1 and the pipe B2 and the auxiliary limiting of the bolt 103. Compared with the first embodiment, the limiting installation of the bolt 103 is more convenient.

[0031] Working principle: First, when the staff needs to connect and fix the pipe A1 and the pipe B2 with several bolts 103, align the pipe openings of the pipe A1 and the pipe B2, slide several bolts 103 into the inner sides of the relative installation grooves 102, and push the limit frame B701 to drive the damping telescopic rod C702 and the outer spring to contract. After the bolts 103 are completely slid into the inner sides of the installation grooves 102, loosen the limit frame B701 and move it close to the limit groove A1021. At this time, the damping telescopic rod C702 and the outer spring pop out of the limit frame B701. After the bolt 103 is limited by sliding into the inner side of the limit groove A1021, the connection between the pipe A1 and the pipe B2 is completed, and several bolts 103 are auxiliary limited to facilitate the subsequent locking process. Then, the staff pushes the limit frames A401 on both sides of the locking frame 4 to drive the damping telescopic rod B402 and the outer spring to contract and slide into the relative locking groove A3 and the inner side of the locking groove B6, and then releases the limit frame A401 to make the damping telescopic rod B402 and the outer spring pop out of the limit frame A401 and slide into the limit groove C601, locking the locking frame 4 After limiting and locking the bolt 103, the staff will limit and lock the other bolts 103 in the same way to prevent the bolt 103 from rotating on the inside of the installation groove 102 and causing friction and wear when the connection between the subsequent pipes A1 and B2 passes through the liquid and vibrates. Finally, the staff will screw one of the nuts 104 on the outer ring of the tail end of the bolt 103, and after the two opposing brackets 1091 and the limiting groove B5 are opposite, the staff will screw the two locking screws 108 to rotate in the inner thread of the thread groove 106 to drive the adjustment After the section frame 107 is raised and the bracket 1091 is close to the limiting groove B5, the retracted damping telescopic rod A109 and the outer spring pop-up bracket 1091 slide into the inner side of the limiting groove B5 to perform a secondary locking process on the bolt 103 and the nut 104. Then, the staff screws other nuts 104 on the outer ring of the tail end of the bolt 103 in the same way and locks them. This can prevent the bolt 103 and the nut 104 from loosening when the connection between the subsequent pipeline A1 and the pipeline B2 passes through the liquid and generates vibration, resulting in leakage at the connection between the pipeline A1 and the pipeline B2.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
