Description

Technical Field

[0001] This utility model relates to the field of instrument fixing technology, specifically to an instrument fixing device. Background Technology

[0002] Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material compositions, and physical property parameters. They have functions such as automatic control, alarm, signal transmission, and data processing. During the processing or repair of instruments and meters, clamping is required. Excessive clamping force can damage the instrument's surface, causing scratches. Excessive clamping force can also lead to deformation. Insufficient clamping force can cause the instrument to fall off during processing or repair, affecting the process. To address these problems, an instrument and meter fixing device is proposed. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide an instrument fixing device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an instrument fixing device, including a rotating support, a bearing fixedly connected to the upper part of the rotating support, a fixing plate rotatably connected to the upper part of the rotating support via the bearing, movable guide rails fixedly connected to the front and rear sides of the upper surface of the fixing plate, threaded clamping rods threadedly connected to the left and right sides of the upper surface of the fixing plate, clamping plates rotatably connected to the lower ends of the two clamping threaded rods, knobs fixedly connected to the upper ends of the two clamping threaded rods, a power component provided in the middle of the upper surface of the fixing plate, and fixing components provided above the fixing plate and on the left and right sides of the power component.

[0005] Preferably, the fixing assembly includes two connecting rods, each with a sliding block fixedly connected to its bottom. The two sliding blocks are slidably connected above two moving guide rails. A first fixing rod is fixedly connected above the two connecting rods, and a third fixing rod is fixedly connected to the bottom of the two connecting rods. A rotating rod is rotatably connected between the two connecting rods at their middle section. Clamping rods are fixedly connected to both ends of the outer surface of the rotating rod. A second fixing rod is fixedly connected below the two clamping rods. At least two tension springs are fixedly connected between the second fixing rod and the first fixing rod.

[0006] Preferably, the upper ends of both clamping rods are fixedly connected to clamping blocks by screws, and rubber pads are glued to the inner sides of both clamping blocks.

[0007] Preferably, the power assembly includes a servo motor, which is fixedly installed at the center of the bottom surface of the fixed plate. The output end of the servo motor passes through the bottom surface of the fixed plate and is fixedly connected to a lifting threaded rod. A threaded block is threadedly connected to the outer surface of the lifting threaded rod. Limiting rods are fixedly connected to the upper surface of the fixed plate and both the front and rear sides of the lifting threaded rod. The limiting rods are slidably connected to the threaded blocks. Connecting rods are rotatably connected to both the front and rear sides of the threaded blocks. The two connecting rods are rotatably connected to the third fixing rod in each of the two sets of fixed assemblies.

[0008] Preferably, a fixing plate is fixedly connected to the upper end of the two limiting rods, and a placement platform is fixedly connected above the fixing plate.

[0009] Compared with the prior art, the advantages of this utility model are as follows: by setting a connecting rod to pull the fixed components on both sides closer to each other along the moving guide rail, after the clamping block contacts the instrument or meter, the clamping rod will rotate with the rotating rod as the threaded block continues to move, thereby stretching the tension spring. This allows for adaptive adjustment of the clamping force when clamping the instrument or meter. The tension spring will adaptively adjust the force according to actual needs during the clamping process, avoiding damage to the surface of the object caused by excessive clamping force. For fragile, precision, or instruments with special surface requirements, it can avoid damage caused by excessive clamping force. Furthermore, the elasticity of the tension spring can slightly buffer the force, avoiding excessive clamping force and maintaining appropriate contact pressure, thereby reducing the possible deformation or wear of the clamped object.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Reference Figure 1-4 As shown, an instrument fixing device includes a rotating support 1, a bearing 2 fixedly connected to the upper part of the rotating support 1, and a fixing plate 3 rotatably connected to the upper part of the rotating support 1 via the bearing 2. By combining the rotating support 1 and the bearing 2, the angle of the fixing plate 3 can be easily adjusted to adapt to the installation requirements of different instruments or meters. Movable guide rails 4 are fixedly connected to both the front and rear sides of the upper surface of the fixing plate 3. Tightening threaded rods 5 are threadedly connected to both the left and right sides of the upper surface of the fixing plate 3. Tightening plates 6 are rotatably connected to the lower ends of the two tightening threaded rods 5. Knobs 7 are fixedly connected to the upper ends of the two tightening threaded rods 5. A power component 8 is provided in the middle of the upper surface of the fixing plate 3. Fixing components 9 are provided on the upper part of the fixing plate 3 and on both the left and right sides of the power component 8.

[0017] Specifically, the fixing component 9 includes two connecting rods 901, each with a sliding block 902 fixedly connected to its bottom. The two sliding blocks 902 are slidably connected above the two moving guide rails 4. A first fixing rod 906 is fixedly connected above the two connecting rods 901, and a third fixing rod 909 is fixedly connected at the bottom between the two connecting rods 901. A rotating rod 903 is rotatably connected between the two connecting rods 901. Clamping rods 904 are fixedly connected to both ends of the outer surface of the rotating rod 903. A second fixing rod 908 is fixedly connected below the two clamping rods 904. At least two tension springs 907 are fixedly connected between the second fixing rod 908 and the first fixing rod 906. The tension springs 907 allow the clamping force to be adaptively adjusted, avoiding the risk of damaging the instrument or meter due to excessive clamping force.

[0018] Specifically, the upper ends of the two clamping rods 904 are fixedly connected to clamping blocks 905 by screws. Rubber pads are glued to the inner side of the two clamping blocks 905. The glued rubber pads increase the friction between the clamping blocks 905 and the instrument or meter, thereby improving the stability of clamping.

[0019] Specifically, the power assembly 8 includes a servo motor 801, which is fixedly installed at the center of the bottom surface of the fixed plate 3. The output end of the servo motor 801 passes through the bottom surface of the fixed plate 3 and is fixedly connected to a lifting threaded rod 802. A threaded block 803 is threadedly connected to the outer surface of the lifting threaded rod 802. The use of the servo motor 801 enables precise control of the lifting threaded rod 802, thereby allowing for precise adjustment of the position and clamping force of the fixed assembly 9. Limiting rods 804 are fixedly connected to the upper surface of the fixed plate 3 and the front and rear sides of the lifting threaded rod 802. The limiting rods 804 are slidably connected to the threaded block 803. Connecting rods 807 are rotatably connected to the front and rear sides of the threaded block 803. The two connecting rods 807 are rotatably connected to the third fixing rod 909 in the two sets of fixed assemblies 9, respectively. The connection method between the connecting rods 807 and the third fixing rod 909 allows the fixed assembly 9 to move synchronously, ensuring a uniform distribution of clamping force on both sides. This design improves the stability and reliability of clamping.

[0020] Specifically, a fixing plate 805 is fixedly connected to the upper end of the two limiting rods 804, and a placement platform 806 is fixedly connected above the fixing plate 805. The fixing plate 805 and the placement platform 806 provide a stable support platform for the instrument or meter, which helps to maintain its stability during operation. At the same time, the design of the placement platform 806 also facilitates the placement and removal of the instrument or meter.

[0021] Working principle: When using this device, firstly, the fixed plate 3 is adjusted to a suitable angle by rotating the bearing 2. Then, the screw rod 5 is turned by the knob 7 to make the clamping plate 6 abut against the mounting plane of the device, limiting the fixed plate 3 to prevent it from rotating. Next, the instrument or meter is placed on the placement platform 806. Then, the servo motor 801 drives the lifting screw rod 802 to rotate, and the screw block 803 moves upward through the screw engagement. This causes the fixing components 9 on both sides to move closer to each other along the moving guide rail 4 through the connecting rod 807. After the clamping block 905 contacts the instrument or meter, the clamping rod 904 will rotate with the rotating rod 903 as the screw block 803 continues to move, thereby stretching the tension spring 907. This allows for adaptive adjustment of the clamping force when clamping the instrument or meter.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
