Description

Technical Field

[0001] This utility model relates to the field of electronic scale technology, and in particular to a protective structure for electronic scales. Background Technology

[0002] Electronic scales are precision weighing instruments designed using modern electronic technology. They mainly consist of a scale body, sensors, a display screen, and operation buttons. To prevent objects from colliding with and damaging the electronic equipment during weighing, and to protect the electronic scale from moisture during use, a protective structure for electronic scales is required.

[0003] A search revealed Chinese Patent Publication No. CN217930494U, which discloses an electronic scale with a protective structure. The scale includes a scale body with a weighing pan on its top; protective pads made of rubber, located on both outer walls of the scale body; and baffles on the left and right sides of the weighing pan, connected to the pan's movable shaft. An adjusting rod is bearing-connected to the front wall of the weighing pan, extending into the pan. A telescopic sleeve is fixedly connected to the inner wall of the protective pad, with one end of the telescopic sleeve away from the protective pad fixedly connected to the outer wall of the scale body. This electronic scale with a protective structure provides cushioning protection to the bottom sides of the scale body through the protective pads, improving its impact resistance. Furthermore, the weighing pan can be freely adjusted to increase or decrease its surface area, accommodating objects of different sizes. However, in practical use, the lack of dehumidification functionality results in poor adaptability to long-term use in extremely high humidity environments, thus reducing the device's reliability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a protective structure for electronic scales, aiming to improve the problem that existing protective structures can only buffer impacts but cannot prevent electronic scales from getting wet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electronic scale protective structure, comprising a base, a scale body fixedly connected to the top right side of the base, a hollow block fixedly connected to the top left side of the base, a bracket fixedly connected to the top of the hollow block, a controller fixedly connected to the top of the bracket, dampers fixedly connected to all four sides of the outer wall of the bracket, a protective cover fixedly connected to the outer side of the dampers, a positioning frame fixedly connected to the inner side of the protective cover, a motor fixedly connected to the top of the hollow block, the output end of the motor passing through the hollow block and fixedly connected to a first bevel gear, a rotating rod rotatably connected to the inner side of the hollow block, fan blades fixedly connected to the front and rear sides of the outer wall of the rotating rod, a second bevel gear fixedly connected to the middle of the outer wall of the rotating rod, the second bevel gear meshing with the first bevel gear, a sealing plate provided on the outer side of the bracket, moisture-absorbing plates fixedly connected to the front and rear sides of the inner wall of the protective cover, and a positioning mechanism provided at the bottom of the base.

[0006] Through the above technical solution: the protective cover and positioning frame provide protection for the controller on the bracket, the damper helps to buffer, after the motor is started, the first bevel gear rotates, and through meshing, the second bevel gear and the rotating rod work together to drive the fan blades to rotate. The airflow is introduced into the device, and then the moisture-absorbing plate filters and dehumidifies, stabilizing the internal environment and effectively enhancing the device's protection and moisture-proof performance.

[0007] As a further description of the above technical solution:

[0008] The base is rotatably connected to four wheels on all four sides. Fixed blocks are fixedly connected to the left and right sides of the outer wall of the base. Two bidirectional threaded rods are rotatably connected to adjacent sides of the two fixed blocks. Moving blocks are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rods. Telescopic plates are rotatably connected to the bottom of the moving blocks. U-shaped plates are rotatably connected to the bottom of the telescopic plates. A chassis is rotatably connected to the bottom of the U-shaped plates.

[0009] Through the above technical solution: the walking wheels give the device the ability to move, the rotating bidirectional threaded rod drives the moving block, and the telescopic plate is linked. Its rotation and extension make the U-shaped plate rise and fall, supporting the device for support. The rotating chassis brings the ability to turn on the spot. This not only facilitates the flexible movement and stable fixation of the device, but also makes it easy to turn in narrow spaces, enhancing the mobility and adaptability of the device.

[0010] As a further description of the above technical solution:

[0011] A knob is rotatably connected to the outer side of the fixing block on the left. The outer side of the knob passes through the fixing block and is fixedly connected to the bidirectional threaded rod.

[0012] The above technical solution allows for easy rotation of the bidirectional threaded rod via a knob.

[0013] As a further description of the above technical solution:

[0014] Spring telescopic rods are fixedly connected to all four sides of the outer wall of the scale body, and the bottom of the spring telescopic rods is fixedly connected to the base.

[0015] The above technical solution improves the stability of the scale during use by using a spring telescopic rod.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the protective cover is provided with sliding grooves on all four sides, and the sliding grooves are slidably connected to the bracket.

[0018] The above technical solution improves the stability between the support and the protective cover by using a sliding groove.

[0019] As a further description of the above technical solution:

[0020] A slot is provided in the middle of the outer wall of the bracket, and the slot engages with the sealing plate.

[0021] The above technical solution allows for easy disassembly, assembly, and fixation of the device through the engagement of the slot and the sealing plate.

[0022] As a further description of the above technical solution:

[0023] A handle is fixedly connected to the outer side of the sealing plate, and a protective sleeve is fixedly connected to the outer side of the handle.

[0024] The above technical solution can improve the comfort of holding the device by using a handle and a protective sleeve.

[0025] As a further description of the above technical solution:

[0026] Positioning blocks are fixedly connected to the front and rear sides of the left end of the base, and positioning holes are provided on the outer side of the positioning blocks.

[0027] The above technical solution allows for the installation and fixation of the device by installing threaded parts inside the positioning holes.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the controller on the protective cover and positioning frame is protected by a damper to enhance protection and buffering. The starting motor makes the first bevel gear rotate, which drives the second bevel gear and the rotating rod to rotate through meshing transmission, thereby driving the fan blade to rotate synchronously. As the fan blade rotates, air flows into the device and is filtered and absorbed by the moisture-absorbing plate, ensuring the stability of the internal environment of the device. This can improve the protection effect of the device and enhance the moisture-proof effect of the device, thereby improving the reliability of the device.

[0030] 2. In this utility model, the device can be moved by the walking wheels, and the rotating bidirectional threaded rod can drive the moving block, so that the telescopic plate moves accordingly. Its rotation and extension cause the U-shaped plate to move up and down, thereby supporting the device. The rotating chassis gives the device the ability to turn in place, which can facilitate the movement and fixing of the device. It can also turn in place in narrow environments, thereby improving the convenience of the device. Attached Figure Description

Detailed Implementation

[0038] 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an electronic scale protective structure, including a base 1, a scale body 3 fixedly connected to the top right side of the base 1 (the scale body 3 can measure weight), a hollow block 4 fixedly connected to the top left side of the base 1, a bracket 5 fixedly connected to the top of the hollow block 4, a controller 7 fixedly connected to the top of the bracket 5 (the controller 7 can control the device), dampers 6 fixedly connected to all four sides of the outer wall of the bracket 5, a protective cover 16 fixedly connected to the outer side of the dampers 6 (the dampers 6 can improve the buffering and protective effect of the protective cover 16), a positioning frame 10 fixedly connected to the inner side of the protective cover 16, and a motor 9 fixedly connected to the top of the hollow block 4 (the output end of the motor 9 passes through the hollow block 4). Hollow block 4 is fixedly connected to a first bevel gear 11. Starting motor 9 can drive the first bevel gear 11 to rotate. Rotating rod 12 is rotatably connected to the inner side of hollow block 4. Fan blades 13 are fixedly connected to the front and rear sides of the outer wall of rotating rod 12. Second bevel gear 14 is fixedly connected to the middle of the outer wall of rotating rod 12. Second bevel gear 14 meshes with first bevel gear 11. Through meshing transmission, second bevel gear 14 can be driven to rotate. As second bevel gear 14 rotates, rotating rod 12 and fan blades 13 rotate. Sealing plate 8 is provided on the outer side of bracket 5. Moisture-absorbing plate 15 is fixedly connected to the front and rear sides of inner wall of protective cover 16. Positioning mechanism 2 is provided at the bottom of base 1.

[0040] Specifically, the protective cover 16 and the inner positioning frame 10 cooperate to build a reliable protective barrier for the controller 7 on the bracket 5. The damper 6 can further enhance the protection and buffering performance, effectively reducing the impact of external impacts on the controller 7. The starter motor 9 drives the first bevel gear 11 to rotate, and through meshing transmission, the second bevel gear 14 and the rotating rod 12 rotate synchronously, thereby driving the fan blade 13 to rotate at high speed. The rotation of the fan blade 13 causes the airflow to continuously flow into the device. At the same time, when the airflow passes through the moisture absorption plate 15, the moisture in it is effectively filtered and adsorbed, thereby ensuring the dryness and stability of the internal environment of the device.

[0041] Reference Figure 1 , Figure 2 and Figure 5The base 1 is rotatably connected to four wheels 201. The outer walls of the base 1 are fixedly connected to the left and right sides of the base 1. The adjacent sides of the two fixed blocks 202 are rotatably connected to the bidirectional threaded rods 203. The outer walls of the bidirectional threaded rods 203 are threadedly connected to the left and right sides of the base 203. Rotating the bidirectional threaded rods 203 can drive the moving blocks 204 to move through the threaded connection. The bottom of the moving blocks 204 is rotatably connected to the telescopic plate 205. When the moving blocks 204 move, they can drive the telescopic plate 205 to move. The bottom of the telescopic plate 205 is rotatably connected to the U-shaped plate 206. The bottom of the U-shaped plate 206 is rotatably connected to the chassis 207. As the telescopic plate 205 rotates and extends, it can drive the U-shaped plate 206 to move. The chassis 207 can make the device rotate in place.

[0042] Specifically, the traveling wheel 201 serves as the moving part of the device, enabling the device to move. The rotating bidirectional threaded rod 203 drives the moving block 204 to generate displacement through its thread transmission. As the position of the moving block 204 changes, the telescopic plate 205 connected to it also moves accordingly. Since the telescopic plate 205 has the ability to rotate and extend, it drives the U-shaped plate 206 to move up and down, which can support the device for fixation. It also enables the device to turn in place by rotating the chassis 207.

[0043] Reference Figure 2 , Figure 3 and Figure 5 A knob 21 is rotatably connected to the outer side of the left fixed block 202. The outer side of the knob 21 passes through the fixed block 202 and is fixedly connected to the bidirectional threaded rod 203. The knob 21 facilitates the rotation of the bidirectional threaded rod 203. Spring telescopic rods 24 are fixedly connected to all four sides of the outer wall of the scale body 3. The bottom of the spring telescopic rods 24 is fixedly connected to the base 1, which can improve the stability of the scale body 3. Slide grooves 17 are opened on all four sides of the inner wall of the protective cover 16. The slide grooves 17 are slidably connected to the bracket 5, which can improve the stability of the movement of the protective cover 16.

[0044] Specifically, the grip knob 21 facilitates the gripping and rotation of the bidirectional threaded rod 203, the spring telescopic rod 24 enhances the stability of the scale body 3 during weighing, and the slide groove 17 enhances the stability of the protective cover 16 during movement.

[0045] Reference Figure 1 , Figure 3 and Figure 4The bracket 5 has a slot 20 in the middle of its outer wall. The slot 20 engages with the sealing plate 8, which facilitates opening and closing the sealing plate 8 for maintenance of the device's interior. A handle 18 is fixedly connected to the outer side of the sealing plate 8, and a protective sleeve 19 is fixedly connected to the outer side of the handle 18, which facilitates gripping and pushing the device to move. Positioning blocks 22 are fixedly connected to the front and rear sides of the left end of the base 1. Positioning holes 23 are opened on the outer side of the positioning blocks 22, which facilitates the installation of cables for pulling and moving the device.

[0046] Specifically, the sealing plate 8 can be fixed and disassembled by engaging with the slot 20 for maintenance of the internal structure. The device can be easily moved by holding the handle 18 and the comfort of holding it is improved by the sleeve 19. The device can be easily pulled and moved by installing a cable in the positioning hole 23 on the positioning block 22.

[0047] Working principle: Before using the device, the controller 7 on the bracket 5 is protected by the protective cover 16 and the inner positioning frame 10. At the same time, the damper 6 enhances the protection and buffering effect. The starting motor 9 drives the first bevel gear 11 to rotate. At this time, the meshing transmission drives the second bevel gear 14 and the rotating rod 12 to rotate, and at the same time drives the fan blade 13 to rotate. The rotation of the fan blade 13 drives the airflow into the device, and at the same time the moisture is filtered and absorbed by the moisture absorption plate 15.

[0048] Furthermore, the device can be moved by the walking wheels 201, and the moving block 204 can be moved by rotating the bidirectional threaded rod 203. As the moving block 204 moves, the telescopic plate 205 moves. At this time, the U-shaped plate 206 moves up and down by rotating and telescopically moving the telescopic plate 205. The U-shaped plate 206 can support the device, and the device can be turned in place by rotating the chassis 207.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
