[0017] Refer toFigures 1 to 4 As shown in the figure, the present utility model provides an installation structure for a weighing sensor, including: a base 1, a fixing plate 3 is fixedly connected inside the base 1, an electromagnet 15 is fixedly connected to the lower surface of the fixing plate 3, and a limiting block 12 and a main spring are symmetrically connected to the upper surface of the fixing plate 3 respectively. The upper end of the main spring is fixedly connected to a buffer plate 4. The upper and lower surfaces of the limiting plate 10 are fixedly connected to a mounting block 8 and a moving block 13 respectively. A receiving groove is correspondingly formed at the lower end of the side of the moving block 13 opposite to the position of the electromagnet 15. A cross plate 14 is slidably connected in the receiving groove through a secondary spring. At the same time, the upper end of the mounting block 8 is fixedly connected to a weighing sensor main body 9 through a main slider 11 and the limiting plate 10, and a weighing plate 7 is fixedly connected to the upper surface of the weighing sensor main body 9.

[0018] In this embodiment, when the weighing sensor main body 9 needs to be installed, first press the limiting plate 10. The limiting plate 10 squeezes the secondary spring and moves into the buffer groove. The weighing sensor main body 9 is embedded in the groove on the upper surface of the mounting block 8, and the main sliders 11 on both sides of the weighing sensor main body 9 are embedded in the corresponding main sliding grooves. Push the weighing sensor main body 9 to move, so that the weighing sensor main body 9 abuts against another group of limiting plates 10. After the squeezed limiting plate 10 is released from the restriction of the weighing sensor main body 9, it can be reset by the squeezed secondary spring, thereby restricting the moving range of the weighing sensor main body 9 and completing the quick installation between the mounting block 8 and the weighing sensor main body 9. Then press down the weighing plate 7. The guide rod 5 connected to the weighing plate 7 is embedded in the corresponding guide hole. The weighing plate 7 pushes the buffer plate 4 to move downward through the mounting block 8 to squeeze the main spring, and the moving block 13 arranged on the lower surface of the buffer plate 4 will pass through the moving port opened on the fixing plate 3, so that the cross plate 14 is located below the fixing plate 3. Start the switch of the electromagnet 15, and the electromagnet 15 attracts the cross plate 14 made of stainless steel to pull the secondary spring out of the receiving groove. When the cross plate 14 is half disengaged, the cross plate 14 abuts against the surface of the electromagnet 15, thereby completing the relative fixation between the fixing plate 3, the buffer plate 4 and the moving block 13. At this time, the upper surface of the limiting block 12 also contacts the lower surface of the buffer plate 4. Therefore, the distance between the limiting plate 10 and the buffer plate 4, with the cooperation of the main spring, enables the weighing sensor main body 9 in this installation structure to have a corresponding buffer structure, reducing the probability of damage to the weighing sensor main body 9 during weighing.

[0019] As a preferred embodiment, the base 1 has a square structure. A through hole is formed in the middle of the upper surface of the base 1, and the mounting block 8 is slidably connected in the through hole. Four groups of extension plates 2 are symmetrically connected to the lower end of the outer side surface of the base 1. The four groups of extension plates 2 are all in the structure of a right-angled triangular prism. At the same time, four groups of guide holes are symmetrically formed at the four corners of the upper surface of the base 1, and guide rods 5 are correspondingly connected to the positions of the weighing plate 7 opposite to the guide holes on the lower surface.

[0020] In this embodiment, as Figure 1 and Figure 2, the provision of the extension plate 2 can assist in enhancing the stability of the installation structure when fixed at the installation location, and the sizes of the guide rod 5 and the guide hole are adapted to each other, which can effectively enhance the stability of the weighing plate 7 during weighing and reduce the probability of accidental tilting of the weighing plate 7.

[0021] As a preferred embodiment, the fixing plate 3 has a square structure, and the cross-section formed by the combination of the fixing plate 3 and the base 1 is in a structure like the Chinese character 'Ri', and a moving opening is correspondingly provided on the surface of the fixing plate 3 at the position opposite to the moving block 13, and the sizes of the moving opening and the moving block 13 are adapted to each other.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the provision of the fixing plate 3 enables the effective limitation of the moving ranges of the buffer plate 4 and the mounting block 8 inside the base 1, assisting in enhancing the overall stability of the installation structure. At the same time, the sizes of the moving opening and the moving block 13 are adapted to each other, which can further reduce the probability of accidental shaking of the moving block 13 and the buffer plate 4 inside the base 1.

[0023] As a preferred embodiment, the two groups of limiting blocks 12 fixedly connected to the upper surface of the fixing plate 3 are both rectangular structures, and the end faces of the two groups of limiting blocks 12 are both T-shaped structures. A plurality of main springs are fixedly connected at equal intervals at the edge of the upper surface of the fixing plate 3, and the buffer plate 4 fixedly connected to the main springs has a square structure.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the provision of the limiting blocks 12 can effectively limit the downward movement range of the buffer plate 4, which can not only ensure that the weighing sensor main body 9 can perform normal weighing through the weighing plate 7, but also avoid excessive extrusion of the main springs by the buffer plate 4 and ensure the service life of the main springs.

[0025] As a preferred embodiment, the moving block 13 inside the base 1 has a cuboid structure, and the cross-section formed by the combination of the moving block 13 and the buffer plate 4 is in a T-shaped structure. The receiving groove opened at the lower end of the moving block 13 has a square structure, and the sizes of the cross plate 14 and the receiving groove are adapted to each other. At the same time, the weighing plate 7 above the base 1 has a square structure, and the side surface of the weighing plate 7 is fixedly connected to the protection plate 6 through a buckle.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3, the size of the horizontal plate 14 is adapted to that of the storage groove, so the stability of the horizontal plate 14 when moving inside the storage groove can be enhanced, ensuring the stability of the connection between the moving block 13 and the fixed plate 3 after a part of the horizontal plate 14 moves out. At the same time, the setting of the protection plate 6 can effectively prevent foreign objects from falling into the installation structure, ensuring the cleanliness inside the installation structure.

[0027] As a preferred embodiment, the installation block 8 is integrally concave. On both sides of the groove on the upper surface of the installation block 8, two groups of main chutes are symmetrically arranged. Both groups of main chutes are strip-shaped structures, and the end faces of the main chutes are dovetail-shaped structures. The sizes of the main chutes and the main sliders 11 are adapted, and the main sliders 11 are fixedly connected to the positions of the weighing sensor on both sides opposite to the main chutes.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the size of the groove on the upper surface of the installation block 8 is adapted to that of the weighing sensor body 9, and the sizes of the main chutes and the main sliders 11 are adapted. Therefore, the groove of the installation block 8 can facilitate the loading and unloading of the weighing sensor body 9 and can also assist in enhancing the stability of the sliding connection of the weighing sensor body 9.

[0029] As a preferred embodiment, the limiting plate 10 is rectangular. The size of the limiting plate 10 is adapted to that of the buffer groove. Two groups of buffer grooves are symmetrically arranged at the bottom of the groove on the upper surface of the installation block 8. A plurality of positioning rods 16 are fixedly connected to the lower surface of the limiting plate 10 at equal intervals. A secondary spring is sleeved on the surface of the positioning rod 16, and positioning grooves are correspondingly arranged at the positions of the buffer groove bottom opposite to the positioning rods 16.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the size of the limiting plate 10 is adapted to that of the buffer groove, which can assist in enhancing the stability of the limiting plate 10 when moving. Moreover, a sealing sleeve is fixedly connected to the opening of the buffer groove, and the sealing sleeve can effectively prevent the limiting plate 10 from accidentally detaching from the buffer groove, enhancing the stability of the sliding connection of the limiting plate 10 in the buffer groove. At the same time, the setting of the positioning rods 16 and the secondary springs enables the limiting plate 10 to have an automatic reset effect, thus facilitating the limitation of the moving range of the weighing sensor body 9 in the groove of the installation block 8 and improving the convenience of loading and unloading the weighing sensor body 9.

[0031] Through the cooperation of the base 1, the buffer plate 4, the fixed plate 3, the installation block 8, the horizontal plate 14 and the electromagnet 15 of the weighing sensor installation structure of the present utility model, the installation structure can facilitate the loading and unloading of the weighing sensor body 9, improve the efficiency of loading and unloading the weighing sensor body 9, and the installation structure as a whole also has good structural strength, reducing the probability of accidental damage to the installation structure.
