DETAILED DESCRIPTION
[0028] Example 1, with reference to Figure 1-Figure 3 As shown, this embodiment discloses a pipeline weld flaw detection device, including a flaw detector body 1, a display screen 2 is provided on one side of the flaw detector body 1, and sockets 8 are symmetrically provided on the top of the flaw detector body 1, a plug 3 is inserted into the inner wall of one of the sockets 8, one end of the plug 3 is fixedly connected to a wire body 4, and one end of the wire body 4 is fixedly connected to a head body 5, an auxiliary device 6 is provided between the plug 3 and the flaw detector body 1, and the auxiliary device 6 includes two extension blocks 61, one side of the two extension blocks 61 is symmetrically fixedly connected to the middle part of the top of the flaw detector body 1, and the inner walls of the two extension blocks 61 are respectively provided with a first threaded rod 62 and a second threaded rod 63, and the first threaded rod 62 and the second threaded rod 63 are fixedly connected at one end thereof. The threads of the threaded rod 63 are of the same size and in opposite directions. The outer surfaces of the first threaded rod 62 and the second threaded rod 63 are both threadedly connected with a clamping plate 64. The two sockets 8 are both arranged between the two clamping plates 64. An anti-slip device 7 is provided on one side of the flaw detector body 1. By setting up two clamping plates 64, under the action of the first threaded rod 62 and the second threaded rod 63, the first threaded rod 62 and the second threaded rod 63 are rotated, and the first threaded rod 62 and the second threaded rod 63 will respectively drive a clamping plate 64 to approach each other until the two clamping plates 64 completely clamp the plug 3, thereby auxiliary fixation between the flaw detector body 1 and the plug 3 can be performed, which is beneficial to prevent the wire body 4 from being pulled by external force and causing the plug 3 to disengage from the socket 8, thereby facilitating the normal use of the flaw detector.
[0029] Reference Figure 2 and Figure 3As shown, the outer surfaces of the first threaded rod 62 and the second threaded rod 63 are fixedly connected to bearings 65, and the outer surfaces of the bearings 65 are fixedly connected to the inner wall of the extension block 61. By providing the bearings 65, the friction between the first threaded rod 62 and the second threaded rod 63 and the two extension blocks 61 can be reduced when the first threaded rod 62 and the second threaded rod 63 are rotated, thereby making the first threaded rod 62 and the second threaded rod 63 more labor-saving when rotating; the ends of the first threaded rod 62 and the second threaded rod 63 that are away from each other are fixedly connected to an operating block 66, and the outer surface of the operating block 66 is provided with a protrusion. By providing the operating block 66, rotating the operating block 66 can drive the first threaded rod 62 and the second threaded rod 63 to rotate. At the same time, the outer surface of the operating block 66 is provided with a protrusion, which can effectively increase the friction on the outer surface of the operating block 66, and has an anti-slip effect when rotating the operating block 66.
[0030] Reference Figure 2 and Figure 3 As shown, the two clamping plates 64 are symmetrically fixedly connected to each other on one side with a rubber block 67, and one side of the rubber block 67 is an arc surface. By setting one side of the rubber block 67 to abut against the outer surface of the plug 3, the friction between the clamping plates 64 and the plug 3 can be increased, thereby making the two clamping plates 64 clamp the plug 3 more firmly; the top of the flaw detector body 1 is symmetrically fixedly connected with a slide bar 68, and the bottom of the clamping plate 64 is symmetrically provided with a slide groove 69, and the outer surface of the slide bar 68 is slidably connected to the inner wall of the two slide grooves 69. By setting the slide bar 68 and the slide groove 69, when the two clamping plates 64 move respectively under the action of the first threaded rod 62 and the second threaded rod 63, the slide groove 69 will be driven to slide synchronously on the outer surface of the slide bar 68, which can limit the clamping plate 64.
[0031] Reference Figure 4 As shown, the anti-slip device 7 includes an elastic belt 71, which is arranged on one side of the flaw detector body 1. By setting the elastic belt 71 and passing the user's hand through the elastic belt 71, the elastic belt 71 can assist in fixing the user's hand and the flaw detector body 1, which is beneficial to prevent the flaw detector body 1 from slipping out of the hand easily.
[0032] Reference Figure 4When the bolt 71 is in the unlocked position, the locking nut 74 is secured to the locking nut 74 by a spring 76 which is secured to the floor by the spring 77. The bolt 76 is secured to the floor by the spring 77 and is easily unlocked.
[0033] Working principle: When it is necessary to fix the plug 3 and the flaw detector body 1, the rotating operating block 66 drives the first threaded rod 62 and the second threaded rod 63 to rotate. Under the limit of the slide bar 68 and the slide groove 69, the first threaded rod 62 and the second threaded rod 63 will respectively drive a clamping plate 64 to move closer to each other until the rubber block 67 on one side of the two clamping plates 64 completely clamps the plug 3, which can assist in fixing the flaw detector body 1 and the plug 3, and is helpful to prevent the wire body 4 from being pulled by external force and causing the plug 3 to be separated from the socket 8; when it is necessary to adjust the elastic band 7 During installation, insert the two threaded pins 73 into the inner wall of the connecting block 72, then sleeve the nut 74 and the washer 75 onto the outer surface of the threaded pin 73, and rotate the nut 74 so that one side of the nut 74 abuts against one side of the washer 75, and one side of the washer 75 abuts against one side of the connecting block 72. This will secure the elastic rope to the flaw detector body 1. At the same time, pass the user's hand through the elastic band 71. The elastic band 71 will then assist in securing the user's hand to the flaw detector body 1, helping to prevent the flaw detector body 1 from slipping out of the hand.
