[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] At present, when using a portable electronic scale, the user holds the handle 100 and hangs the object on the hook 2222 at the bottom of the scale. Due to the restrictions of the usage or environment, the handle 100 is prone to tilt during the weight measurement process, causing the entire electronic scale to tilt, and the sensor inside the electronic scale is not in a horizontal state, so that the measurement result of the object weight has a large error. In addition, if the handle 100 is adjusted and re-measured, it will increase time, reduce efficiency, and increase operating costs.

[0039] See also Figure 1-Figure 9In view of this, the designer has designed a portable electronic scale, which is little affected by the structural form of the handle 100 or even not affected by the handle 100 when in use, has high measurement accuracy and high measurement efficiency, saves time and effort, and reduces costs.

[0041] Please combine Fig. 9 In the portable electronic scale provided in the present embodiment, the connection mode of the handle 100 and the shell 210 is a spherical connection. The handle 100 and the shell 210 can only swing within a certain angle range, and the handle 100 can swing relative to the shell 210 at any angle within the entire circumferential range. In this way, when the operator holds the handle 100, even if the handle 100 is in a tilted state, the electronic scale body 200 can adaptively swing a certain angle relative to the handle 100. In this way, it can be ensured that the electronic scale body 200 is always in a horizontal state, and the weighing module 220 inside the electronic scale body 200 is always in a horizontal state. The weighing result is little affected by the shape of the handle 100 or even not affected by the shape of the handle 100. The weighing result is highly accurate, and the electronic scale is convenient and reliable to use; there is no need to adjust the shape of the handle 100 for repeated weighing, which saves time and effort, improves work efficiency, and reduces work costs.

[0047] It should be understood that the connector 213 can be fixed to the hole wall of the first through hole 214 by bonding or welding. Obviously, in other embodiments, the connector 213, the first half shell 211 and the second half shell 212 can also be fixed in other ways, which are not listed here one by one.

[0048] In addition, in other embodiments, the connector 213 may be integrally formed with one of the first half shell 211 and the second half shell 212 , which has high structural strength, long service life, and reduced assembly errors.

[0049] See also Figure 5 In this embodiment, the handle 100 further includes a grip 120 , the first spherical connecting portion 110 is connected to the grip 120 , and the grip 120 can extend out of the housing 210 from the first through hole 214 , so that the weighing operation can be achieved by holding the grip 120 .

[0050] See also Figure 7 Optionally, the first spherical connection part 110 is set as a spherical head, and the outer surface of the first spherical connection part 110 is set as a partial spherical surface. The first spherical connection part 110 can be snapped into the spherical groove of the connection head 213, and the outer surface of the first spherical connection part 110 can fit tightly with the groove wall of the spherical groove, and the first spherical connection part 110 will not fall out of the avoidance through hole 2132. When the first spherical connection part 110 is snapped into the second spherical connection part 2131, the first spherical connection part 110 and the second spherical connection part 2131 are set with the same sphere center.

[0051] Further, the first spherical connection part 110 is configured as a hemispherical head, and the first spherical connection part 110 has a connected hemispherical surface and a circular surface. The center of the circular surface coincides with the center of the sphere where the hemispherical surface is located. An operating groove 111 is provided on the circular surface, and the operating groove 111 can be a rectangular groove or a "cross" groove, etc. A threaded hole 112 is provided on the hemispherical surface, and the axis of the threaded hole 112 passes through the center of the circular surface and is perpendicular to the circular surface.

[0052] Optionally, the handle 120 includes a first connecting rod 121 and a second connecting rod 122, and one end of the first connecting rod 121 is screwed and fixed to the threaded hole 112 on the first spherical connecting part 110. The first connecting rod 121 is inserted into the avoidance through hole 2132, and one end of the first connecting rod 121 away from the first spherical connecting part 110 extends out from the avoidance through hole 2132, and one end of the first connecting rod 121 away from the first spherical connecting part 110 is connected to the middle position of the length direction of the second connecting rod 122, and the extension direction of the first connecting rod 121 is perpendicular to the extension direction of the second connecting rod 122, that is, the first connecting rod 121 and the second connecting rod 122 form a "T"-shaped structure. Obviously, the first connecting rod 121 and the second connecting rod 122 can also form other non-zero angles.

[0053] See also Figure 6 It should be understood that the first connecting rod 121 and the second connecting rod 122 can be screwed and fixed for easy assembly. That is, when assembling the handle 100 with the connector 213, first separate the first spherical connector 110, the first connecting rod 121 and the second connecting rod 122, insert the first connecting rod 121 into the spherical groove on the connector 213 from the avoidance through hole 2132, and then screw the first connecting rod 121 to the first spherical connector 110 located on one side of the spherical groove; and then screw the second connecting rod 122 to the end of the first connecting rod 121 away from the first spherical connector 110.

[0054] In this embodiment, the first connecting rod 121 and the avoidance through hole 2132 can be slidably matched in the axis extension direction of the avoidance through hole 2132. In this way, the handle 120 has a first position and a second position that can be switched with each other. Figure 8 When the handle 120 is in the first position, the second connecting rod 122 is in contact with the outer surface of the housing 210, and the first spherical connecting part 110 is separated from the second spherical connecting part 2131; at this time, the first connecting rod 121 is basically in the housing 210, and only a small part is exposed to the external environment. The overall structure of the electronic scale is compact and small in size, which is easy to carry and store. When the handle 120 is in the second position, the second connecting rod 122 is separated from the outer surface of the housing 210, and the first spherical connecting part 110 is engaged with the second spherical connecting part 2131. In this state, it is easy to hold the second connecting rod 122 of the handle 120, and the electronic scale body 200 can swing freely relative to the handle 120, which is convenient for weighing and improves the accuracy of the weighing result.

[0055] Optionally, the outer surface of the housing 210 is provided with an anti-slip member, which may be a damping member, and the anti-slip member is provided with an anti-slip groove. When the handle 120 is in the first position, the second connecting rod 122 is clamped in the anti-slip groove of the anti-slip member, and the handle 100 is not easy to automatically slide relative to the housing 210, and the structure is stable and safe. When the handle 100 needs to be used, force is applied to the second connecting rod 122 to overcome the damping and separate the remaining anti-slip grooves.

[0056] In other embodiments, the anti-dropping member may be configured as a magnet, and the second connecting rod 122 may be provided with a magnet or a magnetic portion. When the handle 120 is in the first position, the second connecting rod 122 is magnetically adsorbed and connected to the anti-dropping member.

[0057] It should be understood that in other embodiments, the first spherical connection part 110 can be set as a spherical groove, and the second spherical connection part 2131 can be set as a spherical head. Similarly, the first spherical connection part 110 and the second spherical connection part 2131 can be a mutually matching ball connection structure.

[0058] In other embodiments, the first spherical connection part 110 and the first connecting rod 121 can be integrally formed, or the first spherical connection part 110 is provided with a threaded rod part, and the first connecting rod 121 is provided with a screw hole, and the threaded rod part of the first spherical connection part 110 is screwed and fixed to the screw hole.

[0059] In this embodiment, optionally, the weighing module 220 includes a weighing sensor 221 and a hook 222, the weighing sensor 221 is disposed in the housing 210, and the hook 222 is connected to the weighing sensor 221. Optionally, the hook 222 includes a connecting ring 2221 and a hook 2222, the connecting ring 2221 is connected to the weighing sensor 221, the connecting ring 2221 is penetrated in the second through hole 215, the hook 2222 is connected to the connecting ring 2221, and the hook 2222 can rotate relative to the connecting ring 2221. The hook 2222 is located outside the housing 210 when in use, and the hook 2222 can be rotated to engage with the outer surface of the housing 210 when not in use, so that the overall structure of the electronic scale is compact, small in size, small in space, and easy to store and carry.

[0060] The weighing sensor 221 provided in this embodiment is fixedly connected to the shell 210, and the structural change of the shell 210 directly drives the shape change of the weighing sensor 221. That is, when the handle 100 is tilted, the shell 210 swings freely to a vertical state under the action of gravity, and the weighing sensor 221 is in a horizontal state at this time. The gravity of the items on the hook 2222 always remains perpendicular to the weighing sensor 221, and no component force is generated. The weight data measured by the weighing sensor 221 is the actual weight of the item, and the accuracy is high. Since the handle 100 and the shell 210 are spherical connection structures, the electronic scale body 200 can swing relative to the handle 100 within the first range, ensuring that when the gravity of the item acts on the weighing sensor 221, the gravity direction of the item is always perpendicular to the weighing sensor 221, and the measurement result is highly accurate.

[0061] Furthermore, since the first through hole 214 has an avoidance hole section 2142, when the first connecting rod 121 swings relative to the shell 210, the hole wall of the avoidance hole section 2142 serves to limit the swing angle of the first connecting rod 121. Since the avoidance hole section 2142 is a conical hole, it can provide a larger swing angle for the first connecting rod 121, and the portable electronic scale has a wide range of applications.

[0062] It should be understood that the portable electronic scale provided in this embodiment also includes other components such as a circuit board and a display screen, which are not described in detail in this embodiment. Please refer to the structure of an existing electronic scale.

[0063] The portable electronic scale provided in this embodiment has a simple and reasonable structure. The handle 100 and the electronic scale body 200 are spherically connected, which effectively improves the existing problems of inaccurate weighing caused by the handle 100 not being level, the scale body not being vertical, and the sensor not being level, thereby improving operating efficiency, reducing operating costs, and achieving high accuracy in measurement results.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
