Description

Technical Field

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

[0002] An electronic scale is a type of weighing instrument that uses Hooke's Law or the lever balance principle of forces to determine the mass of an object. According to its structural principle, it can be divided into three main categories: mechanical scales, electronic scales, and electromechanical scales.

[0003] Traditional electronic scales have a relatively fixed structure, and the support rod and display occupy a lot of space during transportation or storage. At the same time, most devices are only equipped with casters or fixed legs. Although devices with casters are easy to move, the casters are prone to slipping during weighing, requiring additional padding with hard objects to secure them, resulting in poor stability. Devices with fixed legs are stable in weighing, but they need to be carried as a whole when moving, making them less portable. Therefore, a portable electronic weighing device is proposed to solve the problems mentioned above. Utility Model Content

This technical solution solves the problems mentioned in the background art, such as the relatively fixed structure of traditional electronic scales, the large space occupied by the support rod and display during transportation or storage, and the fact that most devices are only equipped with casters or fixed legs. Although devices with casters are easy to move, the casters are prone to slipping during weighing, requiring additional padding with hard objects for fixation, resulting in poor stability. Although devices with fixed legs are stable in weighing, they need to be carried as a whole during movement, resulting in low portability.

A connecting seat is fixedly connected to the upper end of the rotating block, and a support frame is fixedly connected to the upper end of the connecting seat. An operation panel is fixedly connected to the upper end of the support frame. A locking tongue is fixedly connected to the rear end of the fixed seat, and a lock body that cooperates with the locking tongue is fixedly connected to the rear end of the connecting seat. The lower part of the base... The base is fixedly connected to four evenly distributed casters. Storage slots are provided at the four corners of the lower end of the base. Rotary shafts are rotatably connected inside the storage slots. Support legs are fixedly connected to the outer surface of the rotating shafts inside the storage slots.

Threaded parts are provided on the outer surface of the rotating shafts. Locking cylinders are threadedly connected to the outer surface of the rotating shafts through the threaded parts. Adjusting studs are threadedly connected to the ends of the four support legs that are close to each other. Leveling blocks are fixedly connected to the ends of the adjusting studs that are away from the support legs.

[0006] Preferably, an anti-slip pad is fixedly connected to one end of the locking cylinder near the base.

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Reference Figures 1-10 As shown, a portable electronic weighing device includes a base 1. A pressure sensor 2 is fixedly connected to the upper end of the base 1. A support plate 3 is fixedly connected to the upper end of the pressure sensor 2. A fixed seat 4 is fixedly connected to the rear end of the pressure sensor 2. A rotating groove 401 is opened at the upper end of the fixed seat 4. A rotating block 5 is rotatably connected inside the rotating groove 401. A connecting seat 6 is fixedly connected to the upper end of the rotating block 5. A support frame 7 is fixedly connected to the upper end of the connecting seat 6. An operation panel 8 is fixedly connected to the upper end of the support frame 7. A locking tongue 9 is fixedly connected to the rear end of the fixed seat 4. A lock body 10 that cooperates with the locking tongue 9 is fixedly connected to the rear end of the connecting seat 6. The lower end of the base 1 is fixedly... The base 1 is connected to four evenly distributed casters 11. Each of the four corners of the lower end of the base 1 has a storage slot 12. The storage slot 12 is rotatably connected to a rotating shaft 13. The outer surface of the rotating shaft 13 is fixedly connected to a support leg 14 on the inner side of the storage slot 12. The left and right rotating shafts 13 pass through the left and right ends of the base 1 and extend to the left and right sides of the base 1, respectively. The outer surface of the rotating shaft 13 has a threaded part 15. The outer surface of the rotating shaft 13 is threadedly connected to a locking cylinder 16 through the threaded part 15. The ends of the four support legs 14 that are close to each other are threadedly connected to an adjusting stud 19. The ends of the adjusting stud 19 that are away from the support legs 14 are fixedly connected to a leveling block 20.

[0016] Furthermore, the upper end of the support plate 3 is fixedly connected with multiple staggered anti-slip protrusions 301. The upper end of the support plate 3 is used to support the weighed object. The anti-slip protrusions 301 can increase the friction between the support plate 3 and the weighed object to prevent the weighed object from sliding. The pressure sensor 2 is used to convert the weight of the weighed object transmitted by the support plate 3 into an electrical signal, which is transmitted to the operation panel 8 through the signal line to realize the acquisition of weight data.

[0017] Furthermore, the support frame 7 supports the operation panel 8, which serves as a human-machine interface for displaying weighing data and performing operations such as zeroing, tare, or unit switching. The support frame 7 can be folded and stored under the drive of the rotating block 5 and the connecting seat 6, reducing the vertical space occupied by the weighing equipment. The locking tongue 9 and the lock body 10 cooperate to form a latch lock structure. When the support frame 7 is rotated and unfolded, the latch lock structure formed by the locking tongue 9 and the lock body 10 can connect and lock the connecting seat 6 and the fixed seat 4, preventing the support frame 7 from rotating accidentally.

[0018] Furthermore, the addition of the movable wheels 11 enables convenient movement of the equipment, allowing operators to simply push the equipment to slide on the ground.

[0019] Furthermore, an anti-slip pad 18 is fixedly connected to one end of the locking cylinder 16 near the base 1, and the other end of the anti-slip pad 18 away from the locking cylinder 16 abuts against the outer surface of the base 1. A rotary handle 17 is fixedly connected to the other end of the locking cylinder 16 away from the base 1.

[0020] Furthermore, the storage slot 12 is used to store the support leg 14, preventing the support leg 14 from being exposed and interfering with the movement of the moving wheel 11 when the moving wheel 11 is used to move the equipment. When the equipment is weighed, the support leg 14 is rotated out and supported on the ground by the leveling block 20, which can replace the moving wheel 11 to bear the weight of the equipment and avoid instability caused by the slippage of the moving wheel 11. The threaded part 15 provides a threaded connection base for the locking cylinder 16. By rotating the locking cylinder 16, the anti-slip pad 18 abuts against the outer surface of the base 1, which can lock the rotating shaft 13 and restrict the rotation of the rotating shaft 13, thereby fixing the position of the support leg 14. The rotating handle 17 provides the operator with a force point to rotate the locking cylinder 16, increasing the rotation torque and preventing the hand from slipping when rotating. The anti-slip pad 18 increases the friction between the locking cylinder 16 and the base 1, improving the locking effect.

[0021] Furthermore, a positioning block 21 is fixedly connected to the lower end of the base 1 near the four legs 14 on the side away from the leveling block 20. The positioning block 21 is used to limit the rotation angle of the legs 14, ensuring that the legs 14 can only rotate to be perpendicular to the ground when they are rotated out, thus avoiding excessive rotation of the legs 14 and resulting in unstable support.

[0022] Furthermore, by rotating the leveling block 20, the extension length of the adjusting stud 19 can be changed, thereby adjusting the height of each corner of the equipment, compensating for uneven ground, and keeping the equipment level. Working principle: In the initial state, the support legs 14 are fully retracted into the storage slot 12 of the base 1, and the support frame 7 is in a folded state. At this time, the equipment only contacts the ground through the four moving wheels 11. The operator only needs to push the base 1 to move the equipment in any direction through the omnidirectional rotation of the moving wheels 11. After the equipment moves to the weighing position, turn the rotary handle 17 to make the anti-slip pad 18 disengage from the base 1. Then turn the support legs 14 out of the storage slot 12 until the support legs 14 are in contact with the positioning block 21. Then turn the rotary handle 17 again to tighten the locking cylinder 16 and fix the position of the support legs 14. If the equipment is tilted, the leveling blocks 20 on the corresponding support legs 14 can be rotated to change the extension length of the adjusting studs 19 until the equipment is level. At this time, the leveling blocks 20 are fully in contact with the ground, the moving wheels 11 are suspended in the air, and the equipment is stably supported by the four support legs 14 without the risk of slippage. Then turn the support frame 7 to unfold it, and then lock the fixed seat 4 and the connecting seat 6 through the locking tongue 9 and the locking body 10. The equipment can then be used.
