Technical Field

[0001] This utility model belongs to the field of weighing technology, specifically relating to a platform scale. Background Technology

[0002] Platform scales are widely used weighing devices suitable for weighing a variety of items. Most common platform scales currently employ a "sandwich" design, with a weighing frame on the top and bottom, and the sensor installed between them. However, this stacked structure results in a relatively large platform scale, increasing the physical exertion for users when moving goods and potentially affecting stability during the weighing process.

[0003] Therefore, to address the aforementioned technical problems, it is necessary to provide a platform scale that has a relatively low height without affecting weighing stability. Utility Model Content

[0014] In one or more embodiments of this utility model, a clearance opening is provided on the vertical plate of the first frame, and the fourth frame can extend into the clearance opening along the height direction of the platform scale; or,

[0015] The third frame has a clearance opening on its vertical plate, and the second frame can extend into the clearance opening along the height direction of the platform scale.

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] Platform scales, as common weighing devices, can be used to weigh various items. In existing designs, platform scales often have a "sandwich" structure, specifically consisting of an upper and lower weighing frame with the sensor installed in the middle. However, this stacking of structures results in a relatively high assembled height for the platform scale. This requires users to expend more physical effort when moving goods and also affects the stability of the weighing process. Therefore, the platform scale of this application has a lower height, effectively solving the aforementioned technical problems. The platform scale of this application will be described in detail below.

[0033] Reference Figures 1 to 4 In one embodiment of this utility model, the platform scale includes an upper weighing frame 1, a lower weighing frame 2, and a sensor 3 disposed between the upper weighing frame 1 and the lower weighing frame 2. In the top view of the platform scale, at least part of the upper weighing frame 1 and the lower weighing frame 2 are staggered. And / or, in the height direction of the platform scale, one of the upper weighing frame 1 and the lower weighing frame 2 forms a clearance space 4 between the two. The platform scale is configured by staggering and / or by using the clearance space 4 to satisfy: H1 ≤ h1 + h2, where H1 is the assembly height of the scale body when the platform scale is unloaded, h1 is the height of the upper weighing frame 1, and h2 is the height of the lower weighing frame 2. For details of H1, h1, and h2, please refer to [reference needed]. Figure 4 The markings in the diagram, and the clearance space 4, can be seen. Figure 6 The marker in the text.

[0034] In this embodiment, the platform scale effectively reduces the overall height of the platform scale after assembly by using an upper weighing frame 1 and a lower weighing frame 2 that are staggered, and / or by having one of the upper weighing frame 1 and the lower weighing frame 2 create a clearance space 4 for the other. This will be further described below.

[0035] Reference Figure 5 and Figure 6 The upper weighing frame 1 includes two opposing first frames 11 and a second frame 12 connecting the two first frames 11. The lower weighing frame 2 includes two opposing third frames 21 and a fourth frame 22 connecting the two third frames 21. In the top view of the platform scale, the first frames 11 and third frames 21 have overlapping areas. A clearance space 4 is provided in the overlapping area of ​​the first frames 11 and third frames 21 on the same side. The second frames 12 and fourth frames 22 are staggered. It should be noted that the clearance space 4 is an open space, not a closed space, so that part of the overlapping area of ​​the first frames 11 and third frames 21 on the same side is located within this clearance space 4.

[0036] Therefore, by providing a clearance space 4 in the overlapping area of ​​the first frame 11 and the third frame 21, one of the first frame 11 and the third frame 21 can be located in the clearance space 4 of the other; while the second frame 12 and the fourth frame 22 are staggered and do not interfere with each other, thereby facilitating one of the first frame 11 and the third frame 21 to enter the clearance space 4 of the other, so as to effectively reduce the total height of the platform scale after assembly.

[0037] In this embodiment, the first frame 11 is provided with the aforementioned clearance space 4 as an example for illustrative purposes. At least a portion of the overlapping area between the third frame 21 and the first frame 11 can be moved into this clearance space 4 to reduce the overall height of the platform scale after assembly. It is understood that in other embodiments, the clearance space 4 can also be provided on the third frame 21, and at least a portion of the structure of the first frame 11 can be moved into this clearance space 4.

[0038] In one optional embodiment, from the top view of the platform scale, the second frame 12 and the fourth frame 22 may have overlapping areas, and the overlapping areas of the second frame 12 and the fourth frame 22 on the same side are provided with a clearance space 4, while the first frame 11 and the third frame 21 are staggered.

[0039] During the design process, if a sheet metal structure is used to manufacture the upper weighing frame 1 and the lower weighing frame 2, it can effectively reduce the overall height of the platform scale after assembly, but its load-bearing capacity is limited. If a tubular profile structure is used, although the load-bearing capacity is stronger, the need to stack the tubing will result in a larger scale body height after installing the sensor 3.

[0040] Based on the above problems, in this embodiment, referring to Figure 5 and Figure 6 The first frame 11 or the third frame 21 includes a vertical plate 51 extending along the height direction of the platform scale and a horizontal plate 52 extending laterally from the vertical plate 51. The vertical plate 51 and the horizontal plate 52 enclose a clearance space 4. The second frame 12 or the fourth frame 22 is connected to the vertical plate 51. The second frame 12 and / or the fourth frame 22 are configured as a tube, and the tube is connected to the vertical plate 51 of the first frame 11 or the third frame 21. In the height direction of the platform scale, the extension height of the vertical plate 51 is greater than or equal to the height of the tube. In this embodiment, both the first frame 11 and the third frame 21 are made of the horizontal plate 52 and the vertical plate 51. In other embodiments, only the first frame 11 or the third frame 21 with the clearance space 4 can be made of the horizontal plate 52 and the vertical plate 51. The first frame 11 or the third frame 21 without the clearance space 4 can be a tube or other shapes. For example, the first frame 11 with the clearance space 4 can be made of a horizontal plate 52 and a vertical plate 51, while the corresponding third frame 21 without the clearance space 4 can be a tube or other shape. This application does not impose specific limitations in this regard.

[0041] Furthermore, in this application, the first frame 11 or the third frame 21 may include a vertical plate 51 and a horizontal plate 52 to form the aforementioned open clearance space 4. In other embodiments, two vertical plates 51 and one horizontal plate 52 may be arranged to form a "U"-shaped structure to form an open clearance space 4. Therefore, in the design of the number and shape of the vertical plates 51 and the horizontal plates 52, as long as they can form an open clearance space 4, allowing one of the first frame 11 and the third frame 21 to enter the other, any design scheme can be understood as the technical solution included in this application.

[0042] The first frame 11 or the third frame 21, through the cooperative design of the horizontal plate 52 and the vertical plate 51, can, on the one hand, work together to form the aforementioned open clearance space 4; on the other hand, compared with a pure plate structure, its load-bearing capacity is superior. Meanwhile, this application sets the second frame 12 and / or the fourth frame 22 as a tubular structure, further enhancing the overall load-bearing performance of the platform scale. Therefore, the platform scale of this application, while ensuring that the load-bearing capacity meets the requirements, achieves an effective reduction in overall height.

[0043] Reference Figure 5 and Figure 6 In this embodiment, the vertical plate 51 of the first frame 11 has a clearance opening 511, and the fourth frame 22 can extend into the clearance opening 511 along the height direction of the platform scale. When the platform scale is under load, the upper frame 1 can undergo a certain deformation relative to the lower frame 2, and the design of the clearance opening 511 ensures that the upper frame 1 and the lower frame 2 do not interfere with each other, thereby ensuring the weighing accuracy of the platform scale. In this embodiment, both the first frame 11 and the third frame 21 are made of a horizontal plate 52 and a vertical plate 51, with the horizontal plate 52 located above the vertical plate 51 so that the opening of the clearance space 4 formed by it faces downward to the left.

[0044] In another optional embodiment, both the first frame 11 and the third frame 21 can be made of a horizontal plate 52 and a vertical plate 51, with the horizontal plate 52 located below the vertical plate 51 so that the notch in the clearance space 4 formed faces upward to the left. Based on this, a clearance opening 511 can be provided on the vertical plate 51 of the third frame 21, allowing the second frame 12 to extend into the clearance opening 511 along the height direction of the platform scale. Similarly, when the platform scale is under load, the upper weighing frame 1 can deform relative to the lower weighing frame 2, and the design of the clearance opening 511 ensures that the upper weighing frame 1 and the lower weighing frame 2 do not interfere with each other, thereby ensuring the accuracy of the platform scale's weighing.

[0045] Reference Figure 3 and Figure 4One of the upper weighing frame 1 and the lower weighing frame 2 is provided with an abutment member 61, and the other is provided with an abutment part 62. When the platform scale is unloaded, there is a gap between the abutment member 61 and the abutment part 62. When the platform scale is loaded, the abutment member 61 and the abutment part 62 abut against each other to limit the minimum assembly height of the platform scale. In this embodiment, the abutment member 61 can be installed on the part of the fourth frame 22 of the lower weighing frame 2 near the upper weighing frame 1, and the abutment part 62 can be provided on the corresponding part of the second frame 12 of the upper weighing frame 1 near the lower weighing frame 2. When the platform scale is loaded, the abutment between the two can prevent the platform scale from being overloaded and damaged by the weighing sensor 3.

[0046] The abutment member 61 may include a connecting plate and a bolt mounted on the connecting plate. The nut at the end of the bolt may abut against the abutment part 62. The bolt may also be replaced by a rod or other structure. The abutment part 62 may be a part of the upper weighing frame 1 or an abutment plate mounted on the upper weighing frame 1. The above is only an example of the installation position of the abutment member 61 and the abutment part 62. In other embodiments, the abutment member 61 and the abutment part 62 may also cooperate between the first frame 11 of the upper weighing frame 1 and the third frame 21 of the lower weighing frame 2, and the position between the abutment member 61 and the abutment part 62 may also be interchanged between the upper weighing frame 1 and the lower weighing frame 2. This application does not impose specific limitations on this.

[0047] Reference Figure 3 and Figure 5 The upper weighing frame 1 includes a first connecting plate 13, and the lower weighing frame 2 includes a second connecting plate 23. Adjacent surfaces of the first connecting plate 13 and / or the second connecting plate 23 are provided with recesses 71, and at least a portion of the sensor 3 is housed within the recesses 71. In this embodiment, two second frames 12 can be provided, connected between two first frames 11, and the first connecting plate 13 can be connected between two second frames 12. Two fourth frames 22 can also be provided, connected between two third frames 21, and the second connecting plate 23 can be connected between two fourth frames 22. This embodiment uses the example of both the first connecting plate 13 and the second connecting plate 23 having recesses 71 for illustrative purposes; in other embodiments, only one of them may have a recess 71. By providing the aforementioned recesses 71, the sensor 3 can be installed within them without increasing the overall height of the weighing platform.

[0048] Reference Figure 5 In another optional embodiment, the upper weighing frame 1 includes a first connecting plate 13, and the lower weighing frame 2 includes a second connecting plate 23. A sensor 3 is installed between the first connecting plate 13 and the second connecting plate 23. When the size of the sensor 3 does not affect the overall height of the platform scale, the aforementioned settling trough 71 may not be required.

[0049] Reference Figure 6The first connecting plate 13 and the second connecting plate 23 have fixing holes 72. Fasteners are installed in the fixing holes 72 to fix the sensor 3. The end of the fastener away from the sensor 3 is embedded in the fixing hole 72. The fastener can be a screw to fix the sensor 3 to the first connecting plate 13 and the second connecting plate 23. The fastener being embedded in the fixing hole 72 can prevent its protruding part from increasing the total height of the platform scale.

[0050] Reference Figure 5 The upper weighing frame 1 has a recessed first mounting position 14 at its top. The platform scale also includes a buffer pad 8 disposed at the first mounting position 14. The height of the side of the buffer pad 8 away from the first mounting position 14 is greater than or equal to the height of the top of the upper weighing frame 1. The buffer pad 8 can buffer the impact pressure caused by objects on the platform scale. In this embodiment, the recessed first mounting position 14 is fitted with the buffer pad 8 so that the installation of the buffer pad 8 does not increase the thickness of the platform scale. Therefore, in this application, the overall height of the platform scale can be reduced by thinning the overall thickness of the platform scale.

[0051] Reference Figure 3 In one optional embodiment, the bottom of the lower weighing frame 2 is recessed with a second mounting position 24, and the platform scale also includes a support leg 9 disposed at the second mounting position 24. The second mounting position 24, in conjunction with the support leg 9, can also reduce the overall height of the platform scale. It is understood that in other embodiments, the aforementioned recessed second mounting position 24 may not be provided, so that a clean space is formed between the lower weighing frame 2 and the ground. Therefore, specific settings can be made according to specific circumstances.

[0052] Reference Figure 1 In one optional embodiment, the upper weighing frame 1 and / or the lower weighing frame 2 are equipped with connecting brackets 10 for connecting accessories, thereby facilitating their assembly with other external equipment and improving their flexibility of use.
