Description

Technical Field

[0001] This utility model relates to the field of metrology and testing equipment technology, and in particular to an adjustable metrology and testing device. Background Technology

[0002] Metrological testing refers to the process of measuring and testing certain specific properties or parameters of an object using specially designed equipment or instruments. These properties or parameters can be various physical quantities such as length, weight, temperature, pressure, current, voltage, and power, or various characteristics such as chemical composition, optical properties, and biological properties.

[0003] In traditional metering and testing devices, the liquid impacts the container as it falls, potentially causing it to tilt, resulting in inaccurate filling or spillage. Excessive impact can even cause the container to detach, wasting liquid and polluting the environment. Patent application CN222882127U discloses an adjustable metering and testing device that uses a motor-controlled two limit plates to protect the container and an electrically controlled telescopic column to adjust the container's height. However, since metering and testing involves small-scale measurements, the instruments used are relatively small, and the adjustment space is limited. Therefore, motor control is inconvenient, leading to poor adjustment accuracy—either over-adjusting or under-adjusting—failing to achieve the intended purpose. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an adjustable measuring and detection device with high adjustment accuracy.

[0005] This utility model is achieved through the following technical solution: An adjustable measuring and testing device includes a base, a hollow support plate on the rear side of the base, a rotating shaft on the upper end of the support plate, clamping guards on the support plates on both sides of the rotating shaft via torsion springs, a gear fixedly mounted on the rotating shaft after it extends into the support plate, the gear meshing with two racks respectively; the gear contacts the inner end of the clamping guards; the rotating shaft has a ratchet structure; a frame intersecting the plane of the support plate is provided on the support plate, a rotating screw is provided at the top of the frame, the rotating screw is threadedly connected to a square slider, the square slider is connected to a support rod, and a clamping device is provided on the support rod.

[0006] A hand crank is provided at the top of the shaft screw.

[0007] A handle is provided at the top of the shaft.

[0008] The ratchet structure is located inside the support plate, and the pawl of the ratchet structure is mounted on the support plate via a drive shaft. The rotating shaft extends out of the support plate and is connected to a rotating rod.

[0009] A return spring is provided between the pawl and the upper end of the support plate.

[0010] An eccentric plate is fixed on the rotating shaft, and a push plate is provided inside the support plate via a spring. The push plate is connected to a crossbar, and the crossbar extends out of the support plate and is connected to an arc-shaped guard plate.

[0011] The beneficial effects of this utility model are: This utility model is equipped with a rotating shaft and a ratchet structure. The gear on the rotating shaft drives the clamping guard plate to rotate, so that the distance between the two clamping guard plates can be freely adjusted according to the size of the container, so that a certain distance is maintained between the guard plate and the container, while still ensuring protection. It is also convenient, simple and quick to operate.

[0012] This utility model also includes a frame, which is intersected with the support plate. The rotation of the shaft screw on the frame drives the square slider inside the frame to move up and down, thereby driving the clamping device to move up and down. The operation is convenient, simple and quick. Attached Figure Description

Detailed Implementation

[0015] The attached figure shows a specific embodiment of this utility model.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 4 As shown, this adjustable measuring and testing device includes a base 1 for placing an electronic scale. A support plate 2 is fixedly installed on the rear side of the base 1. The support plate 2 is vertically placed and hollow inside. Two clamping guard plates 3 are installed on the front side wall of the support plate 2, i.e., the side facing the base 1. One end of the clamping guard plate 3 is located inside the support plate 2, and the other end is located above the base 1 and is arc-shaped. The clamping guard plates 3 are mounted on the support plate 2 by torsion springs 4. When an external force is applied to the part of the clamping guard plate 3 located inside the support plate 2, the clamping guard plate 3 can rotate around the axis of the torsion spring 4, similar to an iron clamp. A rotating shaft 5 is installed on the upper end of the support plate 2. The rotating shaft 5 can only rotate and is located between the two clamping guard plates 3. The lower end of the rotating shaft 5 extends into the support plate 2. A handle 6 is fixedly installed on the part of the rotating shaft 5 outside the support plate 2 for rotating the rotating shaft 5. A gear 8 is coaxially installed on the part of the rotating shaft 5 that extends into the support plate 2. The gear 8 is meshed with two racks 7 respectively. The racks 7 are always in contact with the inner end of the clamping guard plate 3. When the torsion spring 4 is in a relaxed state, the contact point is located in the arc part close to the rotating shaft 5. When the rotating shaft 5 rotates, the contact point gradually moves away from the rotating shaft 5.

[0019] The rack 7 is equipped with a guide groove (existing technology, not shown in the figure).

[0020] To maintain the consistency of rotation of the two clamping guard plates 3, the rack 7 is as follows: Figure 2 The shape shown.

[0021] A ratchet structure 9 is also coaxially provided on the rotating shaft 5. The ratchet structure 9 is located inside the support plate 2. The pawl of the ratchet structure 9 is mounted on the support plate 2 through the rotating shaft 10. The upper end of the rotating shaft 10 extends from the upper end of the support plate 2 and is provided with a rotating rod 11. The rotating rod 11 drives the rotating shaft 10 to rotate, thereby separating the pawl from the ratchet.

[0022] A return spring 12 is installed on the pawl, and the other end of the return spring 12 is also fixed to the inner wall of the upper end of the support plate 2 so that the pawl can continuously limit the ratchet.

[0023] The middle part of the support plate 2 facing the base 1 can be set into an arc shape. A push plate 14 is installed in the arc shape by a spring 13. An eccentric plate 23 is fixedly installed on the rotating shaft 5. The eccentric plate 23 contacts the push plate 14. The push plate 14 is connected to a crossbar 15. After the crossbar 15 extends out from the support plate 2, it is fixedly connected to an arc-shaped guard plate 16.

[0024] A frame 17 is fixedly installed on the upper end of the support plate 2 and the outside of the torsion spring 4. The plane of the frame 17 intersects the plane of the support plate 2. A screw 18 is rotatably connected to the top of the frame 17. A hand crank 19 is installed on the top of the screw 18. After the screw 18 extends into the frame 17, a square slider 20 is threadedly connected. The square slider 20 contacts the inner walls on both sides of the frame 17. The frame 17 plays a limiting and guiding role, so that the square slider 20 can only move up and down under the drive of the screw 18. The square slider 20 is connected to the support rod 21. The support rod 21 is equipped with a clamping device 22. The clamping device 22 is the same as the clamping device 22 on the iron frame, which is existing technology and will not be described in detail.

[0025] The usage process is as follows: Place the electronic scale on the base 1, place the container on the electronic scale, rotate the rotating shaft 5, the rotating shaft 5 drives the gear 8 to rotate, the gear 8 drives the two racks 7 to move in opposite directions, at the same time the eccentric plate 23 rotates, thereby driving the clamping guard plate 3 and the push plate 14 to move closer to the container, until they are close but not in contact with the container and then stop. The ratchet structure 9 positions the rotating shaft 5 so that it cannot rotate automatically. The clamping guard plate 3 and the arc-shaped guard plate 16 protect the container and prevent it from tipping over.

[0026] Place the dispensing bucket onto the clamping device 22 and clamp it. Then, use the hand crank 19 to drive the screw 18 to rotate, thereby moving the dispensing bucket to the appropriate position via the square slider 20.
