[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a weighing unit that is easy to install and has a stable structure includes a body 1 and a weighing platform 2 disposed on the body 1. The weighing platform 2 has a circumferentially arranged notch 21, and a limiting member 4 is movably disposed in the notch 21.

[0029] It also includes a tray 3 with multiple slots 31, and a limiting member 4 is fitted into the slots 31;

[0030] The limiting member 4 is fixedly installed with rubber protrusions 41 that are equidistantly arranged and abut against the inner wall of the groove 31.

[0031] Specifically, the weighing platform 2 is mounted on the machine body 1 using a bracket, and the machine body 1 and the gravity sensor connected to the weighing platform 2 are both existing technologies, which will not be elaborated here.

[0032] Furthermore, the upper surface of the limiting member 4 is flat, and the compressed rubber protrusion 41 adapts to the curvature of the bottom of the tray 3.

[0033] When the tray 3 is placed on the weighing platform 2, the tray groove 31 is aligned with multiple limiting parts 4 for fitting and installation, and multiple rubber protrusions 41 in the tray groove 31 play an anti-slip function. This allows the tray 3 to remain stable in its current tilted state even if it is not in the exact center of the depression of the weighing platform 2. Under the condition of being aligned with the exact center, the tray 3 can maintain maximum stability, greatly shorten the waiting time for value retrieval, and at the same time, it is not easy for the tray 3 to slide around, so that the tray 3 can stably perform the function of placing items.

[0034] As a further embodiment of this utility model, symmetrically arranged rubber side strips 42 are fixedly installed on the limiting member 4, and the rubber side strips 42 slide in cooperation with the inner sidewall of the notch 21.

[0035] Multiple limiting members 4 extend upward from the notch 21 to accommodate different sizes of pallets 3. Under the action of the rubber side strip 42, the upper port of the notch 21 is sealed. That is, the upper surface of the weighing platform 2 is recessed and the notch 21 is sealed, so the upper surface of the weighing platform 2 can be responsible for placing non-powder, non-moisture and other fluid items without the need for the pallet 3, thus ensuring the weighing function of the weighing platform 2 itself.

[0036] As another embodiment further provided in this utility model, the end of the limiting member 4 is also fixedly installed with an elastic piece 43 for abutting against the port of the disk groove 31.

[0037] Specifically, the elastic sheet 43 and the upper surface of the limiting member 4 maintain a predetermined angle, and the elastic sheet 43 after movement maintains an acute angle with the axis of the weighing platform 2.

[0038] During the installation of the tray 3, the elastic plate 43 is inserted into the tray groove 31. During the movement of the limiting member 4, the circumferentially arranged elastic plate 43 provides gripping ability to the tray groove 31, so that the tilted tray 3 uses the tray groove 31 to apply pressure to the elastic plate 43, and the reaction force of the elastic plate 43 can provide the corrective ability to the tray 3.

[0039] As another embodiment further provided by this utility model, a rotating shaft 5 is rotatably provided in the notch 21, and a swing rod 45 inserted into the rotating shaft 5 is fixedly installed on the limiting member 4.

[0040] Specifically, the rotating shaft 5 is hinged with a torsion spring at its rotation position. The torsion spring and its installation method are existing technologies and will not be described in detail here. The range of motion of the limiting member 4 can keep the torsion spring deformed.

[0041] By connecting the limiting member 4 with the swing rod 45 and the rotating shaft 5, the limiting member 4 can rotate around the position of the rotating shaft 5, which makes it convenient for the limiting member 4 to extend out of the notch 21 and maintain a predetermined angle with the horizontal plane, so as to facilitate the supporting and limiting work of the limiting member 4.

[0042] As another embodiment provided in this utility model, a storage opening 22 for the rotating shaft 5 to move is provided in the notch 21.

[0043] The storage opening 22 provides a range of motion for the swing arm 45, allowing the limiter 4 to move more smoothly in the notch 21, while also preventing travel interference of the swing arm 45.

[0044] As another embodiment of this utility model, an arc plate located outside the swing rod 45 is fixedly installed between the limiting member 4 and the rotating shaft member 5.

[0045] Specifically, located Figure 4The rotating shaft 5 has symmetrically arranged arc-shaped pieces, which are specifically elastic metal pieces, and these arc-shaped pieces serve as a connecting element.

[0046] As the swing rod 45 is inserted deeper, the arc plate is compressed and deformed, which facilitates the radial position adjustment of the limiting member 4.

[0047] As another embodiment of this utility model, a symmetrically arranged slider 44 is fixedly installed on the side wall of the limiting member 4, and an arc groove 441 for sliding the slider 44 is provided on the notch 21.

[0048] When the slider 44 moves within the arc groove 441, the tilt angle of the limiting member 4 changes accordingly, while also ensuring the stable movement of the limiting member 4.

[0049] As another embodiment further provided in this utility model, the sliding lower limit member 4 compresses the arc plate deformation.

[0050] The position of the arc plate is changed by the corresponding limiting member 4 through the arc groove 441. At this time, the arc plate is squeezed and deformed and bulges and bends upward.

[0051] As another embodiment provided in this utility model, a plurality of slots 442 are provided on the arc groove 441, and the slider 44 engaged with the slots 442 resets the arc piece.

[0052] Specifically, the card slots 442 are equidistantly arranged at the arc-shaped raised positions of the arc grooves 441.

[0053] When the slider 44 enters the slot 442, the arc plate returns to its original arc shape. Therefore, when manually adjusting the limiting member 4, multiple slots 442 can be used to fix the deflection angle, ensuring the limiting support effect of the limiting member 4.

[0054] As another embodiment further provided in this utility model, the elastic sheet 43 is specifically an elastic metal sheet.

[0055] The elastic sheet 43 provides deformation force to correct the deviation of the pallet 3, so that the pallet 3 is more accurately aligned with the center of the weighing platform 2.

[0056] Working principle: When the tray 3 is placed on the weighing platform 2, the tray groove 31 is aligned with multiple limiting parts 4 for fitting and installation, and multiple rubber protrusions 41 in the tray groove 31 provide anti-slip function. This ensures that even if the tray 3 is not in the exact center of the depression of the weighing platform 2, the tray 3 can remain stable in the current tilted state, greatly shortening the waiting time for value retrieval. At the same time, it is not easy for the tray 3 to slide around, so that the tray 3 can stably perform the function of placing items. When the slider 44 enters the slot 442, the arc plate returns to its original arc state. Therefore, when manually adjusting the limiting parts 4, the multiple slots 442 can be used to fix the deflection angle, ensuring the limiting support effect of the limiting parts 4.

[0057] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
