Description

Technical Field

[0001] This utility model relates to the field of electronic balance technology, and in particular to an anti-shake support structure for electronic balances. Background Technology

[0002] Electronic balances are mainly used to measure the weight of objects. Electronic balances require high measurement accuracy. Even slight vibrations in the electronic balance can cause fluctuations in the sensor signal, affecting the reliability of the measurement results.

[0003] Currently, traditional electronic balances are mainly supported by rubber pads. In actual use, due to uneven placement areas, tilted ground, and other factors, electronic balances often become unstable and tilt. Traditional support methods rely on only a single rubber pad and lack convenient leveling adjustment functions, resulting in uneven force on the balance and increased sensor error. Therefore, an anti-shake support structure for electronic balances is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-shake support structure for electronic balances, which aims to improve the problem of increased sensor error caused by tilting of electronic balances in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-shake support structure for an electronic balance, comprising:

[0006] A support mechanism, on top of which is the electronic balance body, and the support mechanism is located at the four corners of the electronic balance body;

[0007] The support mechanism includes a mounting block, a ball-head rod, a screw, a sleeve, a threaded ring, and a rubber support pad. The mounting block is fixedly connected to the bottom of the electronic balance body. The ball-head rod is embedded in the mounting block and fixedly connected to the screw. The threaded ring is threadedly connected to the screw and rotatably connected to the sleeve. The rubber support pad is fixedly connected to the bottom of the sleeve.

[0008] A level is mounted on the electronic balance body.

[0009] As a further description of the above technical solution:

[0010] An air chamber is provided in the sleeve column, and a piston ring is connected to the piston in the air chamber. The piston ring is fixedly connected to the screw. A vent hole is provided on the rubber support pad and the vent hole is connected to the air chamber.

[0011] As a further description of the above technical solution:

[0012] The rubber support pad has an inlay groove, and a magnetic ring is inlaid in the inlay groove.

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

[0014] The bottom of the rubber support pad is provided with anti-slip texture.

[0015] As a further description of the above technical solution:

[0016] The bottom of the rubber support pad has a notch, and air is contained in the notch after the rubber support pad is placed and fixed.

[0017] As a further description of the above technical solution:

[0018] The top of the sleeve has a through groove, and the diameter of the through groove is larger than the diameter of the screw.

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

[0020] A limiting ring is fixedly connected to the bottom of the mounting block, and the limiting ring is used to limit the angular rotation of the ball joint.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the coordinated design of the support mechanism and the level, the level provides real-time feedback on the tilt status of the balance. The user can drive the screw to rise and fall by rotating the threaded ring, and with the adaptive adjustment of the ball joint's angle, quickly calibrate the level of the balance, ensuring uniform force distribution on the balance body. The embedded connection between the ball joint and the mounting block can accommodate minute angle adjustments, reducing sensing errors caused by tilt and ensuring the measurement accuracy of the electronic balance.

[0023] 2. In this invention, by using a support mechanism, rotating the threaded ring causes the screw to rise, which in turn drives the piston ring to rise, creating a negative pressure state inside the air chamber. Under the negative pressure adsorption, air in the recess at the bottom of the rubber support pad is continuously drawn into the air chamber, reducing the amount of air in the recess and forming a negative pressure cavity. Combined with the external pressure of atmospheric pressure, the rubber support pad is tightly pressed against the placement surface, significantly enhancing the fit and friction between the support structure and the contact surface, effectively preventing the device from shifting or shaking. This synergistic design of "negative pressure pressing + mechanical support" significantly improves the overall stability of the device, avoiding tilting of the electronic balance body or interference from vibration due to unstable placement, further ensuring the measurement accuracy of the electronic balance sensor.

[0030] 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.

[0031] Reference Figures 1-3This utility model provides an embodiment of an anti-shake support structure for an electronic balance, comprising a support mechanism 1 and a level 3. The electronic balance body 2 is mounted on the top of the support mechanism 1, which is located at the four corners of the electronic balance body 2. The level 3 is mounted on the electronic balance body 2. The level 3 allows for the detection of the levelness of the electronic balance body 2, facilitating subsequent leveling by the support mechanism 1. The support mechanism 1 includes a mounting block 101, a ball joint rod 102, a screw 103, a sleeve 104, a threaded ring 105, and a rubber support pad 106. The mounting block 101 is fixedly connected to the bottom of the electronic balance body 2, and the ball joint rod 102 is embedded in the mounting block 101. The ball-head rod 102 is fixedly connected to the screw 103, and the threaded ring 105 is threadedly connected to the screw 103. The threaded ring 105 is rotatably connected to the sleeve 104. The top of the sleeve 104 has a through groove, and the diameter of the through groove is larger than the diameter of the screw 103. The rubber support pad 106 is fixedly connected to the bottom of the sleeve 104. By rotating the threaded ring 105, the screw 103 can be driven to rise and fall, thereby adjusting the height of the support mechanism 1. With the use of the level 3, the levelness of the electronic balance body 2 can be quickly calibrated to ensure that the electronic balance body 2 is subjected to uniform force. The embedded connection between the ball-head rod 102 and the mounting block 101 can accommodate small angle adjustments, reduce the sensing error caused by tilting, and ensure the measurement accuracy of the electronic balance body 2.

[0032] Reference Figures 2-4 An air chamber 1041 is provided in the sleeve 104. A piston ring 1042 is connected to the piston in the air chamber 1041. The piston ring 1042 is fixedly connected to the screw 103. A vent hole 1061 is provided on the rubber support pad 106, and the vent hole 1061 is connected to the air chamber 1041. A notch is provided at the bottom of the rubber support pad 106. After the rubber support pad 106 is placed and fixed, air is stored in the notch. When the screw 103 rises by rotating the threaded ring 105, it can drive the piston ring 1042 to rise, so that a negative pressure state is formed inside the air chamber 1041. Under the negative pressure adsorption, the air in the bottom recess of the rubber support pad 106 is continuously drawn into the air chamber 1041. The amount of air in the recess decreases, forming a negative pressure chamber. Combined with the external pressure of atmospheric pressure, the rubber support pad 106 is tightly pressed onto the placement surface, which greatly enhances the fit and friction between the support structure and the contact surface. This effectively prevents the device from shifting or shaking, improves the overall stability of the device, and avoids tilting of the electronic balance body 2 or interference from vibration due to unstable placement. This further ensures the measurement accuracy of the sensor of the electronic balance body 2.

[0033] Reference Figures 1-3The rubber support pad 106 has an inlay groove, in which a magnetic ring 5 is inlaid and installed. The bottom of the rubber support pad 106 is provided with anti-slip texture. By using the magnetic ring 5, the stability of the electronic balance body 2 is further improved when the device is placed on a metal surface. The anti-slip texture on the bottom of the rubber support pad 106 can increase the friction between the rubber support pad 106 and the placement surface, thereby improving the stability of the electronic balance body 2.

[0034] Reference Figures 2-3 The bottom of the mounting block 101 is fixedly connected to a limit ring 4, which is used to limit the angular rotation of the ball head member 102.

[0035] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0036] Working principle: When using, first place the electronic balance body 2 in the area to be used, ensuring that the support mechanisms 1 at the four corners are evenly stressed, the bottom of the rubber support pad 106 is in full contact with the placement surface, and air is naturally retained in the recess. Observe the level 3 on the electronic balance body 2, and determine whether the balance is tilted according to the indication of the level 3, and determine the position of the support mechanism 1 that needs to be adjusted.

[0037] For the support mechanism 1 on the inclined side, rotate the threaded ring 105, and use the threaded engagement between the threaded ring 105 and the screw 103 to drive the screw 103 to rise axially along the through groove of the sleeve column 104 for adjustment. At the same time, the ball head rod 102 makes a small angle adaptive adjustment in the mounting block 101 to adjust the support mechanism 1 at different positions until the level 3 shows that the electronic balance body 2 has reached a horizontal state.

[0038] Simultaneously, as the screw 103 rises due to the rotation of the threaded ring 105, the piston ring 1042 moves upward synchronously, creating a negative pressure inside the air chamber 1041. Under the suction effect of the negative pressure, air in the recess at the bottom of the rubber support pad 106 is drawn into the air chamber 1041 through the vent 1061, forming a negative pressure cavity. Combined with the external pressure of atmospheric pressure, the rubber support pad 106 is tightly pressed against the placement surface. If the placement surface is made of metal, the magnetic ring 5 further attracts and fixes it; the anti-slip texture at the bottom of the rubber support pad 106 increases friction, and these multiple functions effectively prevent the device from shifting or shaking, filter out minor external vibrations, and ensure the measurement accuracy of the electronic balance body 2.

[0039] 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.
