Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Example 1 refer to Figure 1 This utility model provides a weighing sensor installation module, including a base 10, an upper top plate welding assembly 20, a self-locking bushing 30, a locking washer 40, and a weighing component 50. The weighing component 50 is mounted on the base 10, and the upper top plate welding assembly 20 is sleeved on the outside of the weighing component 50. The upper top plate welding assembly 20 is movably connected to the base 10 via the self-locking bushing 30. During use, placing an object on top of the upper top plate welding assembly 20 causes the weighing component 50 to strain as the assembly moves downwards. During transportation, the upper top plate welding assembly 20 is securely connected to the self-locking bushing 30 via the locking washer 40, preventing damage from shaking during transport and also preventing collisions with the weighing component 50. The self-locking bushing 30 is located on the outside of the weighing component 50, preventing interference with weighing and facilitating disassembly, assembly, transportation, and use.

[0025] Specifically, the weighing assembly 50 includes a weighing sensor 51 and a pressure head 52. The fixed end of the weighing sensor 51 is connected to the base 10, and the measuring end of the weighing sensor 51 extends into the upper top plate welding assembly 20. The bottom of the pressure head 52 is located at the measuring end of the weighing sensor 51, and the top of the pressure head 52 extends to below the top of the upper top plate welding assembly 20, so that the upper top plate welding assembly 20 can cause a slight deformation of the cantilever end of the weighing sensor 51 through the pressure head 52 during use, thereby realizing weighing measurement.

[0026] To further enhance the protection of the load cell 51 during transportation, the weighing assembly 50 preferably also includes an anti-smashing plate 53. One end of the anti-smashing plate 53 is connected to the fixed end of the load cell 51 by a locking bolt 54, and the other end of the anti-smashing plate 53 extends to the outside of the fixed end of the load cell 51, thereby protecting the load cell 51.

[0027] In a further preferred embodiment, to facilitate disassembly and assembly and reduce structural complexity, the bottom of the locking bolt 54 passes through the fixed end of the load cell 51 and connects to the base 10. The locking bolt 54 can be used to simultaneously connect the anti-smashing plate 53 and the load cell 51 to the base 10, which is convenient and simple to operate. In a further preferred embodiment, a grounding cable 55 is connected between the base 10 and the upper top plate welding assembly 20.

[0028] For further explanation, please refer to Figure 2 The pressure head 52 includes a support base 56, a support column 57, and an O-ring 58. The top and bottom of the support base 56 are fitted with O-rings 58. The top of the support base 56 extends into the interior of the support base 56. The support base 56 is tightly connected to the top of the support column 57 through the O-rings 58. At the same time, a locking hole is opened on the side wall of the support base 56 along the radial direction of the support base 56. A locking screw is installed in the locking hole and is pressed against the side wall of the support column 57, thereby ensuring a reliable connection between the support column 57 and the support base 56.

[0029] The bottom end of the support column 57 extends into the measuring end of the load cell 51 and is tightly connected to the load cell 51; the support base 56 is located below the top of the upper top plate welding assembly 20. During transportation, it is preferable that the upper top plate welding assembly 20 and the support base 56 are in contact or spaced apart, preferably spaced apart, to further avoid the upper top plate welding assembly 20 and the support base 56 from contacting each other during transportation and affecting the service life of the load cell 51.

[0030] For further explanation, please refer to Figure 3The self-locking bushing 30 includes a tightening section 31, a limiting section 32, and a threaded section 33. The outer diameters of the tightening section 31, limiting section 32, and threaded section 33 decrease sequentially. The threaded section 33 is threadedly connected to the base 10. The bottom of the upper top plate welding assembly 20 is fitted onto the outside of the limiting section 32, allowing the upper top plate welding assembly 20 to move up and down along the limiting section 32. A locking washer 40 is located on one side of the limiting section 32, and the locking washer 40 is also positioned on the tightening section 31. Between 1 and base 10, the bottom of the upper top plate welding assembly 20 extends into the locking washer 40; during transportation, the locking washer 40, together with the limiting section 32, limits the bottom of the upper top plate welding assembly 20; during transportation, since the locking washer 40 is not fitted on the outside of the limiting section 32, the locking washer 40 can be pulled out directly. At this time, the upper top plate welding assembly 20 can avoid tipping and rotating under the limiting section 32, thus meeting the requirements for weighing.

[0031] Preferably, the top of the tightening section 31 is provided with a hexagonal connector, which facilitates the connection of the self-locking bushing 30 to the base plate 10 with the aid of tools; a relief groove is provided between the limiting section 32 and the threaded section 33 to avoid the problem of loose assembly caused by not being able to tighten the thread completely.

[0032] Further explanation: the upper top plate welding assembly 20 is preferably a π-shaped structure. The upper top plate welding assembly 20 includes an upper top plate 21 and two vertical plates 22. The two vertical plates 22 are connected to opposite sides of the bottom of the upper top plate 21. The vertical plates 22 have an L-shaped structure. The angle between the long side and the short side of the vertical plate 22 is an acute angle. The angle between the long side of the vertical plate 22 and the top plate 21 is also an acute angle. The bottom of the long side of the vertical plates 22 is close to each other. The short side of the vertical plates 22 is parallel to the top of the base plate 10. At this time, the two vertical plates 22 are located on opposite sides of the weighing assembly 50. A limiting hole 23 is opened on the short side of the vertical plate 22. The limiting hole 23 is sleeved on the outside of the limiting section 32, so that the top plate 21 can move up and down along the axis of the self-locking sleeve 30 for weighing. At the same time, a groove is opened at the bottom of the upper top plate 21. The top of the support seat 56 extends into the groove and leaves a gap between it and the top of the groove. The gap can be selected as 0.5mm.

[0033] Preferably, for ease of operation, an operating port 24 is provided on the upright plate 22, which is opposite to the tightening section 31, so that when tightening the self-locking bushing 30 with a tool, it can provide working space for the tool; the inner diameter of the limiting hole 23 is between the outer diameter of the tightening section 31 and the outer diameter of the limiting section 32, so that the upright plate 22 can move on the limiting section 32.

[0034] For further explanation, please refer to Figure 4The locking washer 40 includes an upper locking plate 41, a disassembly arc plate 42, and a lower locking plate 43 connected in sequence. The ends of the upper locking plate 41 and the lower locking plate 43 are engaged with one side of the limiting section 32. That is, arc-shaped grooves that engage with the outer wall of the limiting section 32 are opened at the ends of the upper locking plate 41 and the lower locking plate 43. This allows the locking washer 40 to be pushed to fully contact the outer wall of the limiting section 32 through the arc-shaped grooves during installation, while also preventing the locking washer 40 from sliding along the radial direction of the limiting section 32, thus ensuring stable and reliable locking.

[0035] The upper locking plate 41 is located between the tightening section 31 and the bottom of the upright plate 22, and the lower locking plate 43 is located between the bottom of the upright plate 22 and the base 10. The thickness of the upper locking plate 41 is less than the thickness of the lower locking plate 43, and the gap between the upper top plate welding assembly 20 and the weighing assembly 50 is less than the thickness of the lower locking plate 43. This ensures that after the locking gasket 40 is removed, when the upper top plate welding assembly 20 falls to contact the support base 56, the short side of the upright plate 22 is located above the base 10, thus reserving space for the displacement of the upper top plate welding assembly 20.

[0036] The disassembly arc plate 42 is located on the outside of the upright plate 22. On the one hand, after the disassembly arc plate 42 is installed and locked, the force of the disassembly arc plate 42 driving the upper locking plate 41 and the lower locking plate 43 to flip outward can further ensure the connection stability of the locking washer 40. On the other hand, it is convenient to pull it out by applying force at the disassembly arc plate 42 position with the help of tools or operators. Preferably, the upper surface of the upper locking plate 41 and the lower surface of the lower locking plate 43 are both smooth surfaces to reduce the difficulty of disassembly.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
