Description

Technical Field

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

[0002] An electronic crane scale is an electronic device used to weigh suspended objects. It is commonly used in industrial and commercial fields. Electronic crane scales utilize electronic technology and sensor principles to suspend objects via hooks or straps and measure their weight in real time, displaying the result on a digital screen. Electronic crane scales can accurately measure the weight of suspended objects through advanced sensors and electronic technology, making them particularly suitable for weighing heavy objects. Furthermore, by quickly displaying the weighing results, they reduce the time required for manual weighing and improve operational efficiency.

[0003] Chinese Patent Publication No. CN219956686U discloses an electronic crane scale, including an electronic hook gravity display screen, an electronic hook, and a buckle. The electronic hook is movably connected to the bottom of the electronic hook gravity display screen, and a buckle is provided on the side wall of the electronic hook. A support mechanism and a fixing mechanism are provided on the outer wall of the electronic hook gravity display screen. The support mechanism includes a connecting rod, which is movably connected to the outer wall of the electronic hook gravity display screen and movably connected inside the fixing rod. This electronic crane scale, by providing a support mechanism and by providing a first bolt and a first nut, allows the operator to easily fix the connecting rod after adjusting the height, thus eliminating the need for the operator to hold the electronic hook gravity display screen while lifting objects, thereby reducing the operator's workload. By providing a support rod and a second movable groove, the side wall of the electronic hook gravity display screen is supported, thereby improving the stability of the electronic hook when lifting objects.

[0004] The aforementioned patent mentions that the electronic crane scale uses a first bolt and a first nut to manually adjust the height of the connecting rod, and a support rod to support the side wall of the electronic hook gravity display screen. When the weight and volume of the goods are different, the electronic hook of the electronic crane scale changes accordingly, causing the center of gravity of the electronic crane scale to change. Since the original support mechanism only forms a single-point auxiliary support through the base, support rod and movable rod, the position of the support point and the force range are fixed, making it difficult to cope with the eccentric torque caused by the shift of the center of gravity. This will cause the electronic hook gravity display screen to tilt, reducing the stability of the electronic crane scale. Therefore, we propose a highly stable electronic crane scale. Utility Model Content

[0005] To address the aforementioned issues, a highly stable electronic crane scale is provided. A displacement mechanism drives rollers to move on both sides of the support base, allowing the rollers to adjust the support point position promptly according to changes in the center of gravity. This provides auxiliary support to the electronic crane scale, reducing the impact of eccentric torque on the scale body, thereby improving overall stability and maintaining balance. This solves the technical problem that when the center of gravity of the electronic crane scale changes, it struggles to cope with the eccentric torque generated by the shift in the center of gravity, causing the electronic hook gravity display screen to tilt and reducing the stability of the electronic crane scale.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. By driving the rollers to move on both sides of the support base through the displacement mechanism, the rollers can adjust the position of the support point in a timely manner according to the change of the center of gravity, providing auxiliary support for the electronic crane scale, reducing the impact of eccentric torque on the scale body, thereby improving overall stability and maintaining balance.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-3 As shown, a highly stable electronic crane scale includes a hook gravity display screen 1, a support base 11 on one side of the hook gravity display screen 1, and a self-locking roller 2 at the bottom of the support base 11; a displacement mechanism for driving the self-locking roller 2 to move horizontally on both sides of the support base 11 is provided between the support base 11 and the self-locking roller 2; and a lifting mechanism for driving the hook gravity display screen 1 to move vertically is provided between the hook gravity display screen 1 and the support base 11.

[0026] Specifically, when adjusting the height of the electronic crane scale, the hook gravity display screen 1 can be adjusted via a lifting mechanism to precisely control the hook height, allowing items to be measured at different heights. This eliminates the tedious process of manually moving the hook to adjust its height, saving time and labor, and reducing the workload of operators. At the same time, it avoids operational errors that may occur when manually adjusting the hook height, improving operational safety and reducing the risk of accidents caused by improper operation.

[0027] During the process of adjusting the height of the hook gravity display screen 1 by the lifting mechanism, the self-locking roller 2 can be moved on both sides of the support base 11 through the displacement mechanism. The self-locking roller 2 plays an auxiliary supporting role for the electronic crane scale. The flexible displacement of the self-locking roller 2 on both sides of the support base 11 can distribute the load of the electronic crane scale more evenly, reduce the impact of eccentric torque on the scale body, and thus improve the overall stability of the equipment.

[0028] See Figures 2-6As shown, the displacement mechanism includes a power component 21, a first support assembly, and a bevel gear assembly. The power component 21 is mounted on the support base 11 and provides power for the movement of both the self-locking roller 2 and the hook gravity display screen 1. The first support assembly is located between the support base 11 and the self-locking roller 2, and is used to cooperate with the horizontal displacement of the self-locking roller 2. The bevel gear assembly is located between the power component 21 and the first support assembly, and is used to transmit the power output by the power component 21 to the first support assembly. The first support assembly includes a first screw 22 and a first branch pipe. 23; The first screw 22 is rotatably mounted on the support base 11; the first branch pipe 23 is slidably fitted with the support base 11, and the first branch pipe 23 is threadedly connected to the first screw 22; the bevel gear assembly includes a first bevel gear 24 and a second bevel gear 25; the first bevel gear 24 is rotatably mounted on the support base 11, and the first bevel gear 24 is fixedly connected to the output end of the power component 21; the second bevel gear 25 is rotatably mounted on the support base 11, the second bevel gear 25 meshes with the first bevel gear 24, and the second bevel gear 25 is fixedly connected to the first screw 22.

[0029] Specifically, the power component 21 uses a motor as the implementing element. The threads of the two first screws 22 are in opposite directions. A sliding guide pair is provided between the self-locking roller 2 and the support base 11 to prevent the first branch pipe 23 from driving the self-locking roller 2 to rotate.

[0030] When the electronic crane scale is adjusted in height, the power unit 21 is activated, and the output end of the power unit 21 drives the first bevel gear 24 to rotate. Through the meshing transmission between the second bevel gear 25 and the first bevel gear 24, the first bevel gear 24 can drive the second bevel gear 25 to rotate, which in turn drives the first screw 22 to rotate. At this time, the two first screws 22 rotate in opposite directions, and because the threads of the two first screws 22 are opposite, they cooperate with the slide guide pair provided between the self-locking roller 2 and the support base 11. This slide guide pair is used to limit the rotational movement of the self-locking roller 2 driven by the first branch pipe 23. The first screw 22 and the first branch pipe 23 are threadedly connected, which allows the two first branch pipes 23 to move away from each other, thereby driving the self-locking roller 2 to move on both sides of the support base 11.

[0031] During this process, the self-locking roller 2 maintains stable movement through the guide pair of the slide bar. The flexible displacement of the self-locking roller 2 on both sides of the support base 11 can distribute the load of the electronic crane scale more evenly, reduce the impact of the eccentric torque on the scale body, and thus improve the overall stability of the equipment.

[0032] See Figures 4-6As shown, the lifting mechanism includes a gear transmission assembly and a second support assembly. The second support assembly is disposed between the hook gravity display screen 1 and the support base 11, and is used to cooperate with the vertical displacement of the hook gravity display screen 1. The gear transmission assembly is disposed on the support base 11 and is used to transmit the power output by the power component 21 to the second support assembly. The second support assembly includes a second screw 26 and a second branch pipe 27. The second screw 26 is rotatably disposed on the support base 11. The second branch pipe 27 is slidably engaged with the support base 11 and is threadedly connected to the second screw 26. The gear transmission assembly includes a first gear disc 28 and a second gear disc 29. The first gear disc 28 is rotatably disposed on the support base 11 and is fixedly connected to the output end of the power component 21. The second gear disc 29 is rotatably disposed on the support base 11, meshes with the first gear disc 28, and is fixedly connected to the second screw 26. The pitch of the first screw 22 is greater than the pitch of the second screw 26.

[0033] Specifically, the output end of the power component 21 drives the first bevel gear 24 to rotate, while simultaneously driving the first gear disc 28 to rotate synchronously. Through the meshing transmission between the first gear disc 28 and the second gear disc 29, the first gear disc 28 drives the two second gear discs 29 to rotate in the same direction. Since the second screw 26 and the second branch pipe 27 are connected by threads, the second branch pipe 27 can move linearly along the axial direction of the second screw 26, thereby driving the hook gravity display screen 1 to achieve height adjustment.

[0034] This adjustment method avoids the tedious process of manually moving the hook to adjust the height, while also avoiding errors that may occur due to human operation, effectively improving operational safety.

[0035] Working principle: When the height of the electronic crane scale is adjusted, the power component 21 is activated, which allows the second branch pipe 27 to move linearly along the axis of the second screw 26. This, in turn, drives the hook gravity display screen 1 to adjust the height, thereby precisely controlling the height of the hook. This allows items to be measured at different heights, eliminating the tedious process of manually moving the hook to adjust the height, saving time and labor. At the same time, the first branch pipe 23 drives the self-locking roller 2 to move on both sides of the support base 11. The flexible displacement of the self-locking roller 2 on both sides of the support base 11 can distribute the load of the electronic crane scale more evenly, reduce the impact of eccentric torque on the scale body, and thus improve the overall stability of the equipment.

[0036] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
