A stable electronic crane scale Technical Field

[0001] This utility model relates to the field of electronic crane scale technology, specifically to an electronic crane scale that is stably installed. Background Technology

[0002] In logistics and industrial production, electronic crane scales play an indispensable role as an important weighing device. They can quickly and accurately measure the weight of the suspended object, greatly improving work efficiency and weighing accuracy.

[0003] However, existing electronic crane scales have certain problems in terms of installation stability, which affects their performance and safety to some extent. Currently, electronic crane scales usually have a hanging ring on the top, which is used to connect with an external connecting hook to realize the suspension and weighing functions of the electronic crane scale. However, in actual use, the connection between the hanging ring and the connecting hook is mostly a direct movable connection, that is, the hanging ring is simply mounted on the connecting hook.

[0004] While this connection method achieves the connection between the hanging ring and the connecting hook to a certain extent, it has many drawbacks. Due to the lack of an effective limiting mechanism, the hanging ring is prone to slipping on the connecting hook, which affects the accuracy of weighing and may also cause safety hazards. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As shown in Figures 1-5, this utility model provides a technical solution: a stable electronic crane scale, including an electronic crane scale body 1 and a connecting hook 10. The electronic crane scale body 1 is provided with a hook 2, and a fixed base 9 is fixedly installed on the electronic crane scale body 1. A mounting shell 4 is fixedly installed on the fixed base 9. A stabilizing component 8 is provided on the mounting shell 4, and a hanging ring 3 is rotatably installed on the mounting shell 4. The stabilizing component 8 includes a second positioning plate 816 and a first positioning plate 812 fixedly installed inside the mounting shell 4. A lead screw 815 is rotatably installed on the second positioning plate 816. A second bevel tooth 817 is fixedly installed at the bottom end of the lead screw 815, and a clamping tube 811 is slidably installed on the lead screw 815. The clamping tube 811 passes through the first positioning plate 812, and a slider 813 is fixedly installed on the clamping tube 811. An operating component 7 is provided on the fixed base 9, and the operating component 7 is used to control the up and down movement of the stabilizing component 8.

[0025] As one embodiment of this invention, as shown in Figures 2 and 4, the operating component 7 includes a fixed plate 311 fixedly mounted on a fixed base 9, and a round rod 711 rotatably mounted on the fixed plate 311. The round rod 711 passes through the mounting shell 4. A first bevel tooth 712 is fixedly mounted on one end of the round rod 711, and the first bevel tooth 712 meshes with a second bevel tooth 817. An operating ring 713 is fixedly mounted on the other end of the round rod 711. When the operator rotates the operating ring 713, the round rod 711 rotates accordingly, driving the first bevel tooth 712 to rotate, and then driving the second bevel tooth 817 to rotate through gear meshing. This provides a power source for the movement of the stabilizing component 8, enabling all parts of the entire device to work together and achieve a stable connection between the hanging ring 3 and the connecting hook 10.

[0026] As one embodiment of this invention, as shown in Figures 2 and 4, connecting plates 6 are fixedly installed on both sides of the fixed base 9, and the connecting plates 6 are fixedly connected to the main body 1 of the electronic crane scale through multiple sets of screws 611. When it is necessary to maintain, repair or replace parts of the device, the fixed base 9 can be removed simply by loosening the screws 611. The operation is simple and convenient, reducing maintenance costs and time.

[0027] As one embodiment of this invention, as shown in Figure 4, a fixing bolt 312 is rotatably mounted on the fixing plate 311. After the clamping operation between the hanging ring 3 and the connecting hook 10 is completed, rotating the fixing bolt 312 can make it gradually approach the round rod 711 to reinforce and lock the round rod 711. This can prevent the round rod 711 from rotating accidentally due to external interference, which would cause the clamping state to loosen.

[0028] As one embodiment of this invention, as shown in Figure 4, limit blocks 814 are fixedly installed on both sides of the slider 813, and limit grooves 411 are opened on both sides of the inner wall of the mounting shell 4. The limit grooves 411 are used to implement limit sliding control of the limit blocks 814 to ensure that the limit blocks 814 do not deviate from the preset trajectory during the movement. Through the precise limit of the limit grooves 411, the deviation of the clamping tube 811 during the movement process can be reduced, and the clamping accuracy and stability can be improved.

[0029] As one embodiment of this invention, as shown in Figures 1 and 4, a reinforcing block 911 is fixedly installed between the mounting shell 4 and the fixing base 9, making the structure of the entire assembly more stable.

[0030] As one embodiment of this invention, as shown in Figure 4, a clamping ring 5 is fixedly installed on the clamping tube 811. The clamping ring 5 is arc-shaped, which allows it to better fit the outer surface of the connecting hook 10, increasing the clamping area and improving the clamping force. Two sets of limiting plates 511 are symmetrically fixedly installed at both ends of the clamping ring 5, with a gap between the two sets of limiting plates 511. The clamping ring 5 is wrapped with rubber. When the clamping ring 5 moves upward, the two sets of limiting plates 511 will engage with the outer surface of the hanging ring 3, which not only increases the clamping force but also can accommodate connecting hooks 10 of different sizes. The rubber wrapped on the clamping ring 5 has good friction properties. When the clamping ring 5 abuts against the outer surface of the connecting hook 10, the rubber can increase the friction between the clamping ring 5 and the connecting hook 10, further preventing the connecting hook 10 from slipping during the weighing process and ensuring that the installation of the electronic crane scale is more stable and reliable.

[0031] Working principle: First, the operator moves the main body 1 of the electronic crane scale to a suitable working position and hangs the hanging ring 3 on the main body 1 of the electronic crane scale on the connecting hook 10 to be used. At this time, the hanging ring 3 is simply mounted on the connecting hook 10.

[0032] Then, hold the operating ring 713 by hand and apply rotational force. Since the operating ring 713 is fixedly connected to the round rod 711, the rotation of the operating ring 713 will drive the round rod 711 to rotate synchronously on the fixed plate 311. One end of the round rod 711 is fixedly installed with a first bevel tooth 712. As the round rod 711 rotates, the first bevel tooth 712 will also rotate. Inside the mounting shell 4, the second bevel tooth 817 in the stabilizing component 8 meshes with the first bevel tooth 712. When the first bevel tooth 712 rotates, it will drive the second bevel tooth 817 to rotate through gear meshing. The second bevel tooth 817 is fixedly installed at the bottom end of the lead screw 815, so the rotation of the second bevel tooth 817 will drive the lead screw 815 to rotate synchronously.

[0033] When the lead screw 815 rotates, it will move relative to the clamping tube 811. The clamping tube 811 passes through the first positioning plate 812, and a slider 813 is fixedly installed on it. Limiting blocks 814 are fixedly installed on both sides of the slider 813. Limiting grooves 411 are opened on both sides of the inner wall of the mounting shell 4. The limiting blocks 814 are located in the limiting grooves 411. Under the limiting action of the limiting grooves 411, the clamping tube 811 cannot rotate with the lead screw 815, but can only move linearly along the axis of the lead screw 815.

[0034] As the lead screw 815 continues to rotate, the clamping tube 811 slides upward along the lead screw 815, and the clamping ring 5 also moves upward accordingly, gradually pressing against the outer surface of the connecting hook 10. During the upward movement of the clamping ring 5, the two sets of limiting plates 511 on the clamping ring 5 will engage with the outer surface of the hanging ring 3, making the connecting hook 10 more stably clamped between the clamping ring 5 and the hanging ring 3, and can adapt to connecting hooks 10 of different sizes. In addition, the outer surface of the clamping ring 5 is covered with rubber. When the clamping ring 5 presses against the outer surface of the connecting hook 10, the rubber can increase the friction between the clamping ring 5 and the connecting hook 10, further preventing the connecting hook 10 from slipping during the weighing process, and ensuring that the installation of the electronic crane scale is more stable and reliable.

[0035] After completing the above clamping operation, in order to prevent the round rod 711 from rotating unexpectedly due to external force, which would cause the clamping state to loosen, the operator rotates the fixing bolt 312. During the rotation of the fixing bolt 312, it will gradually approach the round rod 711, and finally reinforce and lock the round rod 711 to ensure that the entire clamping ring 5 remains stable during the weighing process.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
