The connecting component includes a locking block 12, the number of the locking blocks 12 is several, two locking blocks 12 form a group, the locking block 12 is made of metal material, the locking block 12 is overlapped and arranged inside the limiting groove 11, a moving rod 13 is fixedly arranged inside the locking block 12, the longitudinal cross-section of the moving rod 13 is circular, the moving rod 13 is slidably connected to the connecting hole 9, and the setting of the moving rod 13 is convenient for driving the locking block 12 to move forward and backward, and convenient for driving the locking block 12 to rotate, so that the locking block 12 is horizontally aligned with the sliding groove 10 and the limiting groove 11, the moving rod 13 is slidably arranged inside the mounting plate 18, and a moving ring 1 is slidably arranged on the surface of the moving rod 13 4. A spring 15 is fixedly arranged at the rear side of the moving ring 14, and a fixing ring 16 is fixedly arranged at the rear end of the spring 15. Both the moving ring 14 and the fixing ring 16 are annular structures. Both the moving ring 14 and the fixing ring 16 are made of metal materials. The moving ring 14 and the fixing ring 16 have the same specifications. The moving ring 14 and the fixing ring 16 made of metal have higher strength and are not easy to break, which avoids the breaking of the moving ring 14 and the fixing ring 16, resulting in the inability to fix the position of the moving rod 13, thereby preventing the locking block 12 from sliding out of the limiting groove 11. The fixing ring 16 is fixedly arranged on the surface of the moving rod 13, and a hand-held handle 17 is fixedly arranged at the rear end of the moving rod 13. When the female plug 7 After being inserted into the male plug 6, the hand-held handle 17 drives the locking block 12 to move through the moving rod 13, and the hand-held handle 17 pushes the locking block 12 to pass through the sliding groove 10 through the moving rod 13, and then the locking block 12 is rotated to be aligned with the limiting groove 11, and the hand-held handle 17 drives the locking block 12 to be inserted into the limiting groove 11 through the moving rod 13. Since the spring 15 is still in a compressed state, the fixing ring 16 gives the locking block 12 a backward pulling force through the moving rod 13, thereby facilitating the fixing of the position of the male plug 6, avoiding loosening due to vibration between the male plug 6 and the female plug 7, and avoiding the situation where the male plug 6 and the female plug 7 cause weighing errors.
[0022] Specifically, the protective component includes a protective cover 3, which is overlapped and arranged on the top of the circuit board body 2. Fixed plates 4 are fixedly arranged on the left and right sides of the protective cover 3, and fixing bolts 5 are overlapped and arranged inside the fixing plates 4. The number of fixing plates 4 and fixing bolts 5 is four, and the four fixing plates 4 and the four fixing bolts 5 are symmetrically distributed. There are four fixing plates 4 and four fixing bolts 5, which makes the protective cover 3 more firmly installed and makes the circuit board body 2 more firmly installed on the mounting base 1. The fixing bolts 5 are overlapped and arranged on the circuit board body 2, and the fixing bolts 5 are threadedly connected to the mounting base 1. The setting of the protective cover 3 facilitates the protection of the circuit board body 2, and the setting of the fixing plates 4 and the fixing bolts 5 facilitates the installation of the protective cover 3 on the top of the mounting base 1 and facilitates the fixation of the position of the circuit board body 2.
[0023] When in use: insert the female plug 7 into the male plug 6 so that the limit plate 8 contacts the moving ring 14, then rotate the handheld handle 17 to drive the moving rod 13 to rotate, so that the moving rod 13 drives the fixed ring 16 to rotate, so that the fixed ring 16 drives the moving ring 14 to rotate through the spring 15, so that the moving rod 13 drives the locking block 12 to be horizontally aligned with the sliding groove 10, push the handheld handle 17 to drive the moving rod 13 to move forward, so that the moving rod 13 drives the locking block 12 to pass through the sliding groove 10, so that the rear side of the locking block 12 is horizontally aligned with the front side of the limit plate 8, and at the same time the limit plate 8 Push the moving ring 14 to compress the spring 15, and turn the handheld handle 17 again, so that the handheld handle 17 drives the moving rod 13 to rotate, and the moving rod 13 drives the locking block 12 to be horizontally aligned with the limiting groove 11, and pull the handheld handle 17 to drive the moving rod 13 to move backward, so that the moving rod 13 drives the locking block 12 to insert into the limiting groove 11. At this time, the spring 15 is still in a compressed state, so the spring 15 still gives the fixing ring 16 a backward thrust, so that the moving rod 13 gives the locking block 12 a backward pulling force, so that the locking block 12 is fixed inside the limiting groove 11.
[0024] To sum up, in the weighing instrument circuit stable connection component, when the female plug 7 is inserted into the male plug 6, the hand-held handle 17 drives the locking block 12 to move through the moving rod 13, and the hand-held handle 17 pushes the locking block 12 through the sliding groove 10 through the moving rod 13, and then the locking block 12 is rotated to be aligned with the limit groove 11, and the hand-held handle 17 drives the locking block 12 to be inserted into the limit groove 11 through the moving rod 13. Since the spring 15 is still in a compressed state, the fixing ring 16 gives the locking block 12 a backward pulling force through the moving rod 13, thereby facilitating the fixing of the position of the male plug 6, avoiding the loosening of the male plug 6 and the female plug 7 due to vibration, and avoiding the situation where the male plug 6 and the female plug 7 cause weighing errors, which is used to solve the problems raised in the above-mentioned background technology.
