Description

Technical Field

[0001] This utility model relates to the field of household electronic scale technology, specifically to a portable household electronic scale. Background Technology

[0002] Household electronic scales are weighing devices used in daily household use or outdoor travel, shopping and other scenarios. At present, the electronic scales used in households are usually small, lightweight and easy to carry. From the appearance, some portable household electronic scales consist of a pull ring, a weighing body and a hanging hook.

[0003] Common household electronic scales typically use sensor technology to convert the weight of an object into an electrical signal. This signal is then processed by circuitry and displayed, allowing the weight reading of the object to be weighed to be read. For example, the resistance strain gauge sensor, which is widely used at present, works by suspending the material to be weighed on the hook of the electronic scale. The hook deforms downward under the force of the object's weight. This deformation is transmitted to an elastic body, causing the elastic body to undergo a slight deformation. The resistance of the strain gauge changes with the deformation of the elastic body. This change is proportional to the weight of the object. The measuring circuit is responsible for converting the resistance change into a voltage or current signal for subsequent processing.

[0004] Some portable electronic scales (0-25KG) require the user to hold the main body of the scale when weighing due to the weight of the material being weighed. In order to save space, the display of the small electronic scale is usually placed in the center of the scale body. Therefore, when manually lifting the material to be weighed, the hand may block the view or cause inconvenience in reading the value. When weighing heavier items, holding the electronic scale will increase the discomfort of using it. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a portable household electronic scale that reduces the relative impact between the scale body and the weight reading when held, thereby improving holding comfort.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a portable household electronic scale, including a grip cylinder, with connecting rings fixedly connected to both the upper and lower ends of the grip cylinder. A limiting cylinder is fixedly connected to one end of the two connecting rings that are far apart. A connecting cylinder is threadedly connected to the upper end of the limiting cylinder located on the upper side. A display screen is fixedly connected to the upper end of the connecting cylinder. A first fixing ring is sleeved on each of the two connecting rings. A first connecting sleeve is fixedly connected to one side of the first fixing ring. A second fixing ring contacts the inner side of the first fixing ring. The second fixing ring is sleeved on the connecting ring. A second connecting sleeve is fixedly connected to one side of the second fixing ring. The first and second connecting sleeves are nested together. A Velcro fastener is fixedly connected to one side of the first connecting sleeve. A copper contact piece is connected in series to one side of the display screen via a wire. There are two copper contact pieces, and the battery body is abutted between the two copper contact pieces. A support plate is fixedly connected to the bottom end of the copper contact piece located on the bottom side. A PCB circuit board is fixedly connected to the bottom side of the copper contact piece located on the bottom side via a wire. A weighing sensor is connected in series to one side of the PCB circuit board via a wire. A connecting rod is fixedly connected to the bottom end of the weighing sensor. A hook is provided on the bottom side of the connecting rod.

[0007] As a preferred technical solution of this utility model, an arc-shaped abutment plate is fixedly connected to one side of the grip cylinder by bolts. The arc-shaped abutment plate abuts against the PCB circuit board. By setting the arc-shaped abutment plate, the circuit system can be disassembled and maintained.

[0008] As a preferred technical solution of this utility model, one side of the PCB circuit board is in contact with an L-shaped card plate, which is fixedly connected inside the grip. By setting the L-shaped card plate, the PCB circuit board can be easily positioned.

[0009] As a preferred technical solution of this utility model, the grip and the PCB circuit board are fixedly connected to a connecting post on the opposite side of the PCB circuit board, and a spring is sleeved on the two connecting posts. By setting the connecting posts and springs, the PCB circuit board can be easily popped out when the arc-shaped abutment plate is disassembled.

[0010] As a preferred technical solution of this utility model, a support plate is fixedly connected to the bottom side of the grip cylinder, and a limit rod is fixedly connected to all four sides of the bottom end of the support plate. A connecting plate is sleeved on the limit rod, and a swivel plate is threadedly connected to the bottom end of the connecting plate. The end of the swivel plate away from the display screen is fixedly connected to the hook. By setting the limit rod and the swivel plate, stable support can be provided while facilitating the disassembly and replacement of the hook.

[0011] This utility model has the following advantages: by setting a first connecting sleeve and a second connecting sleeve that can be rotated and unfolded on both sides of the grip, the contact surface with the user's arm is increased. At the same time, when not in use, the first connecting sleeve and the second connecting sleeve can overlap and be limited by Velcro, which can reduce the space occupied and make it easy to carry. When the bottom hook is used to hang heavy objects, the reading on the display screen is located on the upper side of the grip, which makes it easy for the user to read the reading and improves the convenience of use.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3The portable household electronic scale shown includes a grip cylinder 1, with connecting rings fixedly connected to both the upper and lower ends of the grip cylinder 1. A limiting cylinder 2 is fixedly connected to the ends of the two connecting rings that are far apart. A connecting cylinder 3 is threadedly connected to the upper end of the limiting cylinder 2, and a display screen 4 is fixedly connected to the upper end of the connecting cylinder 3. A first fixing ring 5 is sleeved on each of the two connecting rings. A first connecting sleeve 6 is fixedly connected to one side of the first fixing ring 5. A second fixing ring 7 contacts the inner side of the first fixing ring 5 and is sleeved on the connecting ring. A second connecting sleeve 8 is fixedly connected to one side of the second fixing ring 7. The second connecting sleeve 8 and the first connecting sleeve 6 are nested together. A Velcro fastener 23 is fixedly connected to one side of the first connecting sleeve 6. The Velcro fastener 23 serves as a limiting element when the first connecting sleeve 6 and the second connecting sleeve 8 are nested together, reducing space occupation and facilitating storage and carrying. A contact copper plate is connected in series to one side of the display screen 4 via a wire. 10. There are two contact copper plates 10, each connected to a different wire, and both wires are connected to one end of the PCB circuit board 12. In addition, the battery body 11 provides power, and the load cell 13 is fixedly connected to the hook 15. When the hook 15 suspends a heavy object, the battery body 11 is in contact between the two contact copper plates 10. The battery body 11 provides power to the entire electronic scale system. It is the energy source for the electronic scale to work and ensure that components such as the display screen 4, PCB circuit board 12 and load cell 13 can operate normally. The bottom of the contact copper plate 10 located on the bottom side is fixedly connected to the support plate 9. The bottom of the contact copper plate 10 located on the bottom side is fixedly connected to the PCB circuit board 12 through wires. The load cell 13 is connected in series to one side of the PCB circuit board 12 through wires. The electrical signal output by the load cell 13 is transmitted to the PCB circuit board 12 through wires. As the core control component of the electronic scale, the PCB circuit board 12 has various built-in circuits and chips. It can amplify, filter, and perform analog-to-digital conversion on the received electrical signals, converting them into digital signals. According to the preset program and algorithm, the digital signals are converted into the weight value of the corresponding object. The weight value obtained after processing by the PCB circuit board 12 is then transmitted to the display screen 4 through wires. After receiving the signal, the display screen 4 displays the weight value in an intuitive digital form, making it convenient for users to read the weight of the object being weighed. The bottom of the load cell 13 is fixedly connected to the connecting rod 14, and the bottom side of the connecting rod 14 is provided with a hook 15. When a heavy object is suspended on the hook 15, the gravity of the object will cause the load cell 13 to deform accordingly. The load cell 13 is a device that can convert force signals into electrical signals. It will output electrical signals of different intensities according to the different weights of the objects being weighed.

[0018] Among them, an arc-shaped abutment plate 16 is fixedly connected to one side of the grip 1 by bolts. The arc-shaped abutment plate 16 abuts against the PCB circuit board 12. By setting the arc-shaped abutment plate 16, the PCB circuit board 12 can be unfolded in the open state, which facilitates inspection and maintenance.

[0019] One side of the PCB circuit board 12 is in contact with an L-shaped card plate 17, which is fixedly connected inside the grip tube 1. By setting the L-shaped card plate 17, it is easy to connect the PCB circuit board 12.

[0020] Among them, the grip 1 and the PCB circuit board 12 are fixedly connected to the connecting post 18 on the opposite side. The two connecting posts 18 are fitted with springs 19. By setting the connecting post 18 and the spring 19, the PCB circuit board can be unfolded when the arc-shaped abutment plate 16 is disassembled.

[0021] The grip 1 has a support plate fixedly connected to its inner bottom side. The support plate has four fixedly connected limit rods 22 on its bottom side. A connecting plate 20 is sleeved on the limit rod 22. A swivel plate 21 is threadedly connected to the bottom of the connecting plate 20. The end of the swivel plate 21 away from the display screen 4 is fixedly connected to the hook 15. The swivel plate 21 makes it easy to replace the hook 15. At the same time, the limit rods 22 ensure the vertical lifting of the hook 15 and improve the stability of the reading displayed on the display screen 4.

[0022] Working principle: When a user needs to weigh a heavy object, it can be suspended through the hook 15. Then, gravity causes the weighing sensor 13 to sense the mass of the object. The weight of the object will cause the weighing sensor 13 to deform accordingly. The weighing sensor 13 is a device that can convert force signals into electrical signals. It will output electrical signals of different intensities according to the weight of the object. Then, the electrical signals output by the weighing sensor 13 are transmitted to the PCB circuit board 12 through wires. The PCB circuit board 12 is the core control component of the electronic scale. It has various circuits and chips built in. It can amplify, filter, and perform analog-to-digital conversion on the received electrical signals to convert them into digital signals. According to the preset program and algorithm, the digital signals are converted into the weight value of the corresponding object. The weight value obtained after further processing by the PCB circuit board 12 is then transmitted to the display screen 4 through wires. After receiving the signal, the display screen 4 displays the weight value in an intuitive digital form, making it convenient for users to read the weight of the weighed object. When the device is not in use, the arrangement of the first fixing ring 5, the first connecting sleeve 6, the second fixing ring 7, the second connecting sleeve 8, and the Velcro 23 allows the electronic scale to be nested together and limited by the Velcro 23, thereby reducing the space occupied by the electronic scale and making it easy to store and carry. When maintenance is required, the arc-shaped abutment plate 16 is removed. Since the connecting post 18 on the opposite side of the grip cylinder 1 and the PCB circuit board 12 is fitted with a spring 19, the spring 19 will cause the PCB circuit board 12 to be unfolded, making it easy to perform maintenance operations. The L-shaped clamping plate 17 is fixed inside the grip cylinder 1 and contacts the PCB circuit board 12, playing the role of connecting and stabilizing the PCB circuit board 12. The receiving plate, limiting rod 22, connecting plate 20, and rotating plate 21 on the bottom side of the grip cylinder 1 work together. The swivel plate 21 facilitates the replacement of the hook 15, and the limiting rod 22 ensures that the hook 15 can be raised and lowered vertically when suspending heavy objects, reducing swaying and thus improving the stability of the reading displayed on the display screen 4.
