Description

Technical Field

[0001] This utility model relates to the technical field of windproof equipment for electronic balances, and in particular to a foldable windproof device for electronic balances. Background Technology

[0002] An electronic balance is a precision instrument that uses electromagnetic force to balance the weight of an object for weighing. It uses an electromagnetic balance sensor to achieve high-precision measurement and has an automatic detection system, calibration device and overload protection function. The foldable windproof device of the electronic balance is mainly used to reduce the interference of air flow on precision weighing. The foldable design combines portability and protection.

[0003] Existing technologies, such as CN209820615U, disclose a windproof cover for an electronic scale, which includes a box-shaped body with a door. The base of the box-shaped body has a plurality of limiting grooves or holes. A limiting post, which mates with the limiting grooves or holes on the base, is located on the upper part of the electronic scale body. A hole for the electronic scale tray support to pass through is located in the center of the base. This invention, by using a base with limiting grooves or holes, allows the windproof cover to be fixed to the balance by rotation, and can also be disassembled by rotating in the opposite direction. It is simple and convenient to operate, and has a simple structure.

[0004] To address the issue of wind protection for existing electronic balances, which currently use fixed covers for wind protection, these covers cannot be folded. When not in use, they require significant storage space, and during transportation, their volume cannot be compressed, necessitating larger packaging and transport vehicles, leading to increased transportation costs. Furthermore, they are prone to damage from collisions and are relatively consumable. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing windproof device of electronic scales is a fixed cover for wind protection. When the fixed windproof cover cannot be folded, it occupies a large storage space when not in use. In addition, because the volume cannot be compressed during transportation, it may require larger packaging and transportation tools, resulting in increased transportation costs. It is also easy to be damaged by collisions and is relatively consumable. Therefore, a foldable windproof device for electronic balance is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foldable windproof device for an electronic balance, comprising an electronic balance body, a display screen, buttons, and a protective device. The display screen is fixedly connected to the surface of the electronic balance body, the buttons are disposed on the surface of the electronic balance body, and the electronic balance body is provided with a first rotating seat and a second rotating seat. Both the first rotating seat and the second rotating seat are fixedly connected to the upper surface of the electronic balance body. The surface of the first rotating seat is provided with a protective device, which includes a back plate and a side plate. The back plate is rotatably connected to the surface of the first rotating seat, and the side plate is rotatably connected to the surface of the second rotating seat.

[0007] Furthermore, the number of the second rotating seats is two sets and they are symmetrically arranged, and the surface of the back plate is provided with fixing grooves, the number of the fixing grooves is four sets and they are symmetrically arranged.

[0008] Furthermore, the side plate is fixedly connected to a locking rod, and there are two sets of locking rods arranged symmetrically. The locking rods are engaged with the inner wall of the fixing groove, and a limit block is fixedly connected to the surface of each locking rod.

[0009] Furthermore, the surface of the back plate is provided with a sliding groove, and there are two sets of sliding grooves arranged symmetrically. A sliding rod is fixedly connected to the inner wall of the sliding groove.

[0010] Furthermore, a spring is fixedly connected to the inner wall of the slide groove. There are two sets of springs arranged symmetrically. The springs are sleeved and connected to the surface of the slide rod. An L-shaped rod is fixedly connected to the end of the spring away from the slide groove. The L-shaped rod is slidably connected to the inner wall of the slide groove.

[0011] Furthermore, a top plate is rotatably connected to the upper surface of the back plate, a rotating hinge is fixedly connected to the surface of the top plate, a panel is rotatably connected to the surface of the rotating hinge, a rotating rod is fixedly connected to the surface of the top plate, the rotating rod is in two sets and symmetrically arranged, and a torsion spring is fixedly connected to the surface of the top plate.

[0012] Furthermore, the torsion spring is sleeved and connected to the surface of the rotating rod, and a magnetic strip is fixedly connected to the side of the torsion spring away from the top plate. A magnetic block one is fixedly connected to the surface of the side plate, and a magnetic block two is fixedly connected to the surface of the panel. The magnetic strip is magnetically connected to both magnetic block one and magnetic block two.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a protective device, the back plate is more convenient to use when the main body of the electronic scale is protected from wind. To this end, the back plate and the two sets of side plates are rotated, so that the back plate and the side plates rotate along the axis of the rotating seat, pushing the two sets of L-shaped rods, so that the L-shaped rods slide to the inner side of the slide groove, so that the spring is deformed and compressed under force. Then, when the back plate and the side plates are adjusted to a vertical state, the locking rod connected to the side plate is locked into the fixed groove. Then the two sets of L-shaped rods are released, so that the springs rebound after losing force. Then the springs push the L-shaped rods, and the locking rods are stably locked into the fixed groove, so that the side plates and the back plate are stably connected.

[0015] 2. In this utility model, the top plate is then rotated and folded along both ends, and then the top plate, back plate, and front panel are all folded at right angles. Then, the magnetic strip is rotated, causing the torsion spring to be deformed and twisted. Then, the magnetic strip is magnetically connected to two sets of magnetic blocks, so that the front panel is stably attached to the side plate. By setting a protective device, it is easy to protect the main body of the electronic scale from wind, avoiding the existing electronic scale's windproof device, which is a fixed cover. When the fixed windproof cover cannot be folded, it occupies a large storage space when not in use, and during transportation, because the volume cannot be compressed, it may require larger packaging and transportation tools, resulting in increased transportation costs. It is also easy to be damaged by collisions, which is more consumable. This effectively improves the ease of use and practicality of the equipment. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides a technical solution: a foldable windproof device for an electronic balance, including an electronic balance body 1, a display screen 2, a button 3 and a protective device 4. The display screen 2 is fixedly connected to the surface of the electronic balance body 1. The button 3 is disposed on the surface of the electronic balance body 1. The electronic balance body 1 is provided with a first rotating seat 41 and a second rotating seat 43. Both the first rotating seat 41 and the second rotating seat 43 are fixedly connected to the upper surface of the electronic balance body 1. The surface of the first rotating seat 41 is provided with a protective device 4.

[0024] The specific setup and function of protective device 4 will be explained below.

[0025] In this embodiment: the protective device 4 includes a back plate 42 and a side plate 44. The back plate 42 is rotatably connected to the surface of the first rotating seat 41, and the side plate 44 is rotatably connected to the surface of the second rotating seat 43.

[0026] Specifically, there are two sets of second rotating seats 43 arranged symmetrically, and the surface of the back plate 42 is provided with fixing grooves 45, which are arranged symmetrically in four sets.

[0027] Specifically, the side plate 44 is fixedly connected to a locking rod 46. There are two sets of locking rods 46 arranged symmetrically. The locking rods 46 are engaged with the inner wall of the fixing groove 45. Limiting blocks 47 are fixedly connected to the surface of each locking rod 46.

[0028] The effect achieved by the above components is as follows: by setting the connection between the locking rod 46 and the fixing groove 45, it is convenient to connect and fix the side plate 44 and the back plate 42, so that the side plate 44 and the back plate 42 are both vertical. The limiting block 47 is set to prevent the locking rod 46 from dislodging from the inner wall of the fixing groove 45.

[0029] Specifically, the surface of the back plate 42 is provided with a sliding groove 48. There are two sets of sliding grooves 48 arranged symmetrically, and a sliding rod 49 is fixedly connected to the inner wall of the sliding groove 48.

[0030] The effect achieved by the above components is that by setting the slide bar 49, the L-shaped bar 411 can slide stably along the surface of the slide bar 49, avoiding misalignment of the L-shaped bar 411 and causing it to rub and get stuck against the inner wall of the slide groove 48.

[0031] Specifically, a spring 410 is fixedly connected to the inner wall of the slide groove 48. There are two sets of springs 410 arranged symmetrically. The springs 410 are sleeved and connected to the surface of the slide rod 49. An L-shaped rod 411 is fixedly connected to the end of the spring 410 away from the slide groove 48. The L-shaped rod 411 is slidably connected to the inner wall of the slide groove 48.

[0032] The effect achieved by the above components is that, by setting the spring 410, the elastic force of the spring 410 can push the L-shaped rod 411 back to its original position after the L-shaped rod 411 is unrestrained.

[0033] Specifically, a top plate 412 is rotatably connected to the upper surface of the back plate 42, a rotating hinge 413 is fixedly connected to the surface of the top plate 412, a panel 414 is rotatably connected to the surface of the rotating hinge 413, a rotating rod 415 is fixedly connected to the surface of the top plate 412, there are two sets of rotating rods 415 arranged symmetrically, and a torsion spring 416 is fixedly connected to the surface of the top plate 412.

[0034] The effect achieved by the above components is as follows: by setting the torsion spring 416, after the magnetic strip 417 loses its magnetic attraction, the deformation elastic force of the torsion spring 416 can drive the magnetic strip 417 to rotate and reset along the axis of the rotating rod 415, so that the magnetic strip 417 and the top plate 412 are in the same horizontal position and attached.

[0035] Specifically, the torsion spring 416 is sleeved and connected to the surface of the rotating rod 415. A magnetic strip 417 is fixedly connected to the side of the torsion spring 416 away from the top plate 412. A magnetic block 418 is fixedly connected to the surface of the side plate 44. A magnetic block 419 is fixedly connected to the surface of the panel 414. The magnetic strip 417 is magnetically connected to both the magnetic block 418 and the magnetic block 419.

[0036] The effect achieved by the above components is that by setting the connection between the magnetic strip 417 and the magnetic block, it is easy to stably fix the side plate 44, the front panel 414 and the top plate 412, and avoid displacement.

[0037] Working principle: By setting up the protective device 4, the back plate 42 is more convenient to use when the main body of the electronic scale is protected from wind. Rotating the back plate 42 and the two sets of side plates 44 makes the back plate 42 and the side plates 44 rotate along the axis of the rotating seat, pushing the two sets of L-shaped rods 411, causing the L-shaped rods 411 to slide to the inside of the slide groove 48, causing the spring 410 to be deformed and compressed. Then, when the back plate 42 and the side plates 44 are adjusted to the vertical position, the locking rod 46 connected to the side plate 44 is locked into the fixing groove 45. Then, the two sets of L-shaped rods 411 are released, causing the spring 410 to rebound after losing force. Then, the spring 410 pushes the L-shaped rods 411, and then the locking rod 46 is stably locked into the fixing groove 45, so that the side plate 44 and the back plate 42 are stably connected.

[0038] The top plate 412 is then rotated and folded along both ends. The top plate 412, back plate 42, and front panel 414 are then folded at right angles. The magnetic strip 417 is then rotated, causing the torsion spring 416 to be deformed and twisted. The magnetic strip 417 is then magnetically connected to the two sets of magnetic blocks, making the front panel 414 stably fit against the side plate 44. By setting the protective device 4, the main body of the electronic scale is easily protected from wind. This avoids the problem that the existing windproof devices of electronic scales are fixed covers. When fixed windproof covers cannot be folded, they occupy a large storage space when not in use. During transportation, because the volume cannot be compressed, larger packaging and transportation tools may be required, leading to increased transportation costs. They are also easily damaged by collisions and are relatively consumable. This effectively improves the ease of use and practicality of the equipment.
