Description

Technical Field

[0001] This utility model application relates to the field of electronic weighing instrument technology, specifically to an electronic weighing instrument with an anti-sinking structure. Background Technology

[0002] Electronic weighing instruments are modern weighing and measurement devices integrating electronic technology, sensor technology, and microprocessor technology, and represent the mainstream development direction in the contemporary weighing field. They convert the weight of an object into an electrical signal through high-precision sensors, which is then rapidly processed by a microprocessor to clearly display the weight data in digital form, achieving automation and precision in the weighing process. Electronic weighing instruments come in a variety of types, from small portable electronic scales to large dynamic truck scales, from high-precision analytical balances to explosion-proof chemical scales, meeting the weighing needs of different industries and scenarios. They possess significant advantages such as fast weighing speed, high accuracy, good stability, and strong anti-interference capabilities. Some high-end models also support data storage, printing, network transmission, and remote monitoring functions, greatly improving the efficiency and intelligence of weighing management. Widely used in industrial production, logistics and transportation, commercial trade, scientific research and testing, and other fields, they have become a key tool for improving weighing efficiency and ensuring data accuracy, and are an indispensable basic equipment in the modern metrology field.

[0003] Chinese Patent Publication No. CN222812454U discloses an electronic weighing instrument with a leveling structure, comprising an electronic weighing instrument body. A vertically arranged fixed rod is fixedly connected to one side of the electronic weighing instrument body, and a display screen is rotatably connected to the top of the fixed rod. Leveling mechanisms are symmetrically arranged on both sides of the electronic weighing instrument body and fixedly connected to it. Each leveling mechanism includes a fixed plate fixedly connected to one side of the electronic weighing instrument body, and a threaded column rotatably connected to the top of the fixed plate, penetrating the fixed plate and vertically arranged. A horizontally arranged handle is fixedly connected to the top of the threaded column. This electronic weighing instrument, through the leveling mechanism, fixed plate, threaded column, handle, universal ball joint, universal ball seat, level plate, and bubble level, can level the electronic weighing instrument body, preventing deviations in weighing results due to insufficient levelness during weighing.

[0004] The electronic weighing instrument described in the aforementioned patent documents uses a leveling mechanism for support and adjustment. However, when used in the field, the leveling mechanism is prone to sinking into the soil, causing the instrument to tilt and affecting its weighing accuracy. Therefore, an electronic weighing instrument with an anti-sinking structure is proposed. Utility Model Content

[0005] To address the aforementioned issues, an electronic weighing instrument with an anti-sinking structure is provided. This structure utilizes the movement of the bottom ends of two sets of connecting rods, either moving away from or towards each other, causing the connecting rods to drive the base longitudinally. When the base descends, it causes an expansion plate to contact the ground, thereby increasing the contact area between the base and the ground and effectively preventing the electronic weighing instrument from sinking when in contact with the ground during weighing.

[0006] To address the existing technical problems, this application provides an electronic weighing instrument with an anti-sinking structure, including a mounting platform, a support mechanism disposed at the bottom of the mounting platform, and an anti-sinking mechanism disposed at the bottom of the mounting platform. The anti-sinking mechanism includes a height-adjustable base, an expansion plate horizontally disposed at the bottom of the base, a relatively movable connecting rod mounted on the base, a fixing plate fixed at the top of the connecting rod, and the upper end face of the fixing plate fixedly connected to the lower end face of the mounting platform. The anti-sinking mechanism also includes telescopic mechanisms located on both sides of the fixed plate.

[0007] As one technical solution of this application, the top of the base is symmetrically provided with clearance grooves, and a rotatable bidirectional threaded rod is horizontally installed in the clearance groove. Two sets of movable seats that can move relative to each other are symmetrically installed on the bidirectional threaded rod, and the bottom end of the connecting rod is hinged to the top of the movable seat.

[0008] As one technical solution of this application, one end of the bidirectional threaded rod can extend outside the relief groove, and a handwheel for driving its rotation is fixed to the extended end of the bidirectional threaded rod.

[0009] As one technical solution of this application, the telescopic mechanism includes a limiting sleeve with its bottom end hinged to the base, and a slide rail is provided on the inner wall of the limiting sleeve; An extension rod capable of moving along its central axis is installed inside the limiting sleeve. The end of the extension rod away from the limiting sleeve is hinged to the bottom of the fixed plate. A sliding groove is provided on the outer wall of the extension rod to slide with the slide rail.

[0010] As one technical solution of this application, a slot is provided on the lower end face of the extension rod; The limiting sleeve has a horizontally installed locking block near the top of the sleeve. The locking block can rotate and is adapted to the locking slot. A handle is fixed to one end of the block.

[0011] As one technical solution of this application, a stop block for limiting the handle is fixed on the side of the telescopic mechanism.

[0012] The advantages of this utility model application compared to the prior art are: This application utilizes the mutual separation or proximity of the bottom ends of two sets of connecting rods to cause the connecting rods to drive the base to move longitudinally. When the base moves downward, it causes the expansion plate to contact the ground, thereby increasing the contact area between the base and the ground and effectively preventing the electronic scale from sinking when it contacts the ground during weighing.

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figures 1-6As shown, an electronic weighing instrument with an anti-sinking structure includes a mounting platform 1, a support mechanism 2 disposed at the bottom of the mounting platform 1, and an anti-sinking mechanism 3 disposed at the bottom of the mounting platform 1. The anti-sinking mechanism 3 includes a height-adjustable base 31, an expansion plate 314 horizontally disposed at the bottom of the base 31, a relatively movable connecting rod 33 mounted on the base 31, a fixing plate 34 fixed at the top of the connecting rod 33, and the upper end face of the fixing plate 34 fixedly connected to the lower end face of the mounting platform 1. The anti-sinking mechanism 3 also includes telescopic mechanisms 35 located on both sides of the fixed plate 34.

[0022] When the bottom ends of the two sets of connecting rods 33 move away from or towards each other, the connecting rods 33 will drive the base 31 to move longitudinally. When the base 31 moves downward, it will cause the expansion plate 314 to contact the ground, increasing the contact area between the base 31 and the ground and effectively preventing the electronic scale from sinking when it contacts the ground during weighing. At the same time, when the base 31 moves longitudinally, it will also cause the telescopic mechanism 35 to extend, allowing the telescopic mechanism 35 to support the fixed plate 34, thereby improving the stability of the fixed plate 34.

[0023] See Figure 2 , Figure 3 and Figure 4 As shown, the base 31 has symmetrical relief grooves 311 on its top. A rotatable bidirectional threaded rod 312 is horizontally installed in the relief groove 311. Two sets of movable seats 32 that can move relative to each other are symmetrically installed on the bidirectional threaded rod 312. The bottom end of the connecting rod 33 is hinged to the top of the movable seat 32.

[0024] When the bidirectional threaded rod 312 rotates, it drives the two sets of movable seats 32 mounted on it to move relative to each other or move away from each other. When the movable seats 32 move away from each other, the movable seats 32 drive the connecting rod 33, which is hinged at its top, to gradually become horizontal. At this time, the connecting rod 33 drives the base 31 to move upward through the movable seats 32. When the movable seats 32 move closer to each other, the movable seats 32 drive the connecting rod 33, which gradually becomes vertical, thereby causing the connecting rod 33 to drive the base 31 and the expansion plate 314 downward.

[0025] See Figure 2 , Figure 3 and Figure 4 As shown, one end of the bidirectional threaded rod 312 can extend out of the relief groove 311, and a handwheel 313 for driving its rotation is fixed to the extended end of the bidirectional threaded rod 312.

[0026] To effectively drive the bidirectional threaded rod 312 to rotate, a handwheel 313 is fixed to the extended end of the bidirectional threaded rod 312. When the handwheel 313 is turned, it drives the bidirectional threaded rod 312 to rotate synchronously, thereby enabling the bidirectional threaded rod 312 to effectively drive the movable seat 32.

[0027] See Figure 5 and Figure 6 As shown, the telescopic mechanism 35 includes a limiting sleeve 351 with its bottom end hinged to the base 31, and a slide rail 352 is provided on the inner wall of the limiting sleeve 351. An extension rod 36 that can move along its central axis is installed inside the limiting sleeve 351. The end of the extension rod 36 away from the limiting sleeve 351 is hinged to the bottom of the fixing plate 34. A groove 361 that slides with the slide rail 352 is provided on the outer wall of the extension rod 36.

[0028] As the base 31 descends, it causes the limiting sleeve 351 to gradually become more vertical. At this time, the extension rod 36 inside the limiting sleeve 351 also becomes more vertical and extends outward from the limiting sleeve 351. When the base 31 ascends, it causes the limiting sleeve 351 assembly to become more vertical, at which point the extension rod 36 retracts. To ensure the stability of the extension rod 36, a slide rail 352 is provided on the inner wall of the limiting sleeve 351. When the extension rod 36 moves along the central axis of the limiting sleeve 351, it slides along the slide rail 352 through the groove 361, thus ensuring the stability of the extension rod 36.

[0029] See Figure 5 and Figure 6 As shown, a slot 362 is provided on the lower end face of the extension rod 36; A locking block 37 is horizontally installed inside the limiting sleeve 351 near the top. The locking block 37 can rotate and is adapted to the slot 362. A handle 38 is fixed to one end of the locking block 37.

[0030] When the extension rod 36 extends along the central axis of the limiting sleeve 351, it pushes the locking block 37 to rotate clockwise, allowing the extension rod 36 to extend smoothly. To prevent the extension rod 36 from falling back after extension, a slot 362 is provided on one side of the extension rod 36. After the extension rod 36 has completed its extension, the locking block 37 rotates counterclockwise under the gravity of the handle 38, and the top of the locking block 37 engages in the slot 362, allowing the slot 362 and the locking block 37 to cooperate and limit the extension rod 36. When the handle 38 is lifted upwards, it drives the locking block 37 to rotate clockwise. At this time, the handle 38 causes the locking block 37 to separate from the slot 362, facilitating the smooth retraction of the extension rod 36.

[0031] See Figure 5 and Figure 6As shown, a stop 353 for limiting the handle 38 is fixed to the side of the telescopic mechanism 35.

[0032] By fixing the stop block 353 to one side of the telescopic mechanism 35, the telescopic mechanism 35 can effectively limit the handle 38 and effectively prevent the handle 38 from rotating excessively.

[0033] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
