[0029] Embodiment 1

[0030] In order to solve the technical problems in the background technology, the following impact-resistant bellows weighing sensor is provided:

[0031] Combination Figure 1-5 As shown, the impact-resistant bellows weighing sensor provided by the utility model comprises a weighing sensor 22 and a bellows 10 sleeved on the weighing sensor 22, threaded columns 12 are fixedly installed at both ends of the weighing sensor 22, and a protective component is arranged between the two threaded columns 12;

[0032] The two threaded columns 12 are provided with a left connection end 1 and a right connection end 11 at the ends facing away from each other. A plug-in barrel 16 is fixedly provided on the left connection end 1. A plug-in connector 17 is inserted in the plug-in barrel 16. A wire 5 is connected to one end of the plug-in connector 17. A mounting nut 4 is threadedly sleeved on the plug-in connector 17 and the plug-in barrel 16. The two mounting nuts 4 cooperate with each other. Two left threaded holes 14 are provided on the left connection end 1. A left mounting bolt 2 is threadedly connected in each left threaded hole 14. A first limiting assembly is provided between the two left mounting bolts 2 and the left connection end 1. A right threaded hole 13 is provided on the right connection end 11. A right mounting bolt 9 is threadedly connected in the right threaded hole 13. A second limiting assembly is provided between the right mounting bolt 9 and the right connection end 11.

[0033] The first limit assembly includes a left plug pin hole 15 and two left matching holes 18. The left plug pin hole 15 is opened through the left side surface of the left connecting end 1 and communicates with the two left threaded holes 14.

[0034] Each left matching hole 18 is formed on the corresponding left mounting bolt 2 , and a left plug pin 3 is inserted into the left plug pin hole 15 . The right end of the left plug pin 3 passes through the two left threaded holes 14 in sequence and is inserted in cooperation with the two left matching holes 18 .

[0035] In specific use, this solution is improved on the existing technology. When it is necessary to fix the end of the sensor output line on the equipment, the operation is as follows: the two left mounting bolts 2 are threadedly inserted into the corresponding left threaded holes 14 in sequence and connected to the equipment. Then, in order to increase the stability of the connection with the equipment, since the left plug pin hole 15 is opened through the left side surface of the left connecting end 1 and is connected with the two left threaded holes 14, a left plug pin 3 is inserted in the left plug pin hole 15, and the right end of the left plug pin 3 passes through the two left threaded holes 14 in sequence and is inserted in cooperation with the two left matching holes 18. In this way, each left mounting bolt 2 can be limited in the corresponding left threaded hole 14 by inserting the left plug pin 3. Compared with the existing technology, the stability of the connection between the bellows weighing sensor and the equipment can be further increased. At the same time, the overall structural design is exquisite and compact, which is conducive to promotion.

[0036] The second limiting assembly includes a right plug pin hole 21 and a right matching hole 20. The right plug pin hole 21 is formed on the right side surface of the right connecting end 11 and communicates with the right threaded hole 13.

[0038] In specific use, this solution is improved on the existing technology. When it is necessary to install the force-bearing end of the sensor on the weighing platform, the operation is as follows: the right mounting bolt 9 is threadedly inserted into the right threaded hole 13 and connected to the weighing platform. Then, in order to increase the stability of the connection with the weighing platform, since the right plug-in pin hole 21 is opened through the right side surface of the right connecting end 11 and is connected to the right threaded hole 13, a right plug-in pin 19 is inserted in the right plug-in pin hole 21, and the left end of the right plug-in pin 19 passes through the right threaded hole 13 and is inserted into the right matching hole 20. In this way, the right mounting bolt 9 can be limited in the right threaded hole 13 by inserting the right plug-in pin 19. Compared with the existing technology, the stability of the connection between the bellows weight sensor and the weighing platform can be further increased. At the same time, it is simple to operate and highly practical, which is conducive to improving the accuracy of subsequent weighing.

[0041] The protection assembly includes two internal thread rings 7, each of which is threadedly sleeved on a corresponding threaded column 12, and a plurality of "X"-shaped baffles 8 are evenly arranged between the two internal thread rings 7. Both ends of each "X"-shaped baffle 8 are provided with mounting screws 6 and connected to the corresponding internal thread ring 7 through the mounting screws 6. The external structure of the internal thread ring 7 is in the shape of a regular polygon.

[0042] In specific use, based on the first embodiment, in order to prevent the bellows weighing sensor from being damaged, a protective component can be set on its periphery to play a certain protective role, which is beneficial to prevent the bellows weighing sensor from being hit by foreign objects. The operation is as follows: each internal threaded ring 7 is threadedly sleeved on the corresponding threaded column 12. Since the external structure of the internal threaded ring 7 is a regular polygon, the "X"-shaped baffle 8 and the two internal threaded rings 7 are installed by installing screws 6 and distributed in a circular array. In this way, the bellows weighing sensor can be effectively prevented from being hit by external forces, which is beneficial to increasing its service life.
