Description

Technical Field

[0001] This utility model relates to the field of support technology for metrological verification, and in particular to a metrological verification support. Background Technology

[0002] Metrological verification, or simply verification, is the procedure for determining and confirming whether measuring instruments meet legal requirements. It includes checking and marking and / or issuing verification certificates. Metrological verification plays a vital role in metrology work. It is an important measure to standardize instrument values ​​and ensure the accuracy and consistency of measuring instruments. It is an important form of value transfer or traceability. It is one of the most important practical applications of metrology and a fundamental task of metrology departments. During metrological verification experiments, verification stands are often needed to assist in completing the experiments.

[0003] A search revealed that a publicly authorized certificate, with publication number CN212567469U, is available for a calibration bracket for metrological verification. Although this utility model allows for the placement of instruments via hooks, the lack of a corresponding fixing mechanism between the collar and the crossbeam makes it prone to slippage, potentially causing adjacent instruments to collide. Therefore, further improvements are needed.

[0004] To address these shortcomings, we have proposed a metrological verification support. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metrological verification support.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a metrological verification support, including a base, with support rods symmetrically installed on the top surface of the base about a center line, and a crossbar between the two support rods. A collar is slidably sleeved on the surface of the crossbar, and a hook is provided at the bottom end of the collar. A fixing hole is provided through the outer surface of the collar, and an adjustment hole is provided through the surface of the crossbar. The collar is fixed to the crossbar by inserting a rod through the fixing hole and the adjustment hole. By using the adjustment hole, the fixing hole, and the inserting rod in combination, it is easy to fix the collar to the crossbar, thereby ensuring the stability of the metrological verification instrument below the hook and avoiding interference caused by left and right swaying. During operation, the operator can slide the collar to a designated position on the crossbar, then align the fixing hole with the adjustment hole, and then fix it through the fixing hole and the adjustment hole by inserting the rod. This method is simple to operate and facilitates the fixing of the collar.

[0007] Preferably, a placement box is provided above the base between the two support rods. A clamping assembly is provided inside the placement box, containing a first arc-shaped clamping plate and a second arc-shaped clamping plate. The surfaces of the first and second arc-shaped clamping plates are fixed to the inner wall of the placement box by springs. Pull ropes are provided on the surfaces of the first and second arc-shaped clamping plates, with pull rods at the bottom of the ropes. This clamping assembly facilitates the clamping and placement of metrological verification instruments. During operation, the operator pulls the pull rope downwards using the pull rod, compressing the springs under the pull of the ropes to separate the first and second arc-shaped clamping plates. The operator then places the metrological verification instrument between the first and second arc-shaped clamping plates and slowly releases the pull rod. The elastic potential energy of the springs then causes the first and second arc-shaped clamping plates to clamp and fix the instrument between them. This method is simple to operate and facilitates the fixation of the instrument.

[0008] Preferably, a through hole is provided on the outer surface of the placement box. By providing the through hole, it is easy to allow the pull rope to pass through.

[0009] Preferably, multiple clamping components are provided, and the multiple clamping components are installed at equal intervals inside the placement box. By providing multiple clamping components, it is easier to increase the amount of fixation of the appliance.

[0010] Preferably, multiple adjustment holes are provided, and the multiple adjustment holes are equally spaced on the outer surface of the crossbar. By providing multiple adjustment holes, it is convenient to adjust the distance between two adjacent collars and avoid interference between the devices on the hook.

[0011] Preferably, a rubber pad is provided on the bottom surface of the base. By providing the rubber pad, the anti-slip performance of the base can be improved, and the stability of the bracket can be improved when it is placed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model, through the combined use of adjustment holes, fixing holes and plug rods, facilitates the fixing of the collar to the crossbar, thereby ensuring the stability of the measuring and verification instrument below the hook and avoiding interference caused by left and right swaying. During operation, the operator can slide the collar to the designated position on the crossbar, then align the fixing hole with the adjustment hole, and then fix it by inserting the plug rod through the fixing hole and adjustment hole. This method is simple to operate and facilitates the fixing of the collar. By setting up a clamping component, it is easy to clamp and place the measuring and verification instrument. During operation, the operator pulls the pull rope down through the pull rod, and then the spring is compressed under the traction of the pull rope to separate the first arc-shaped clamp and the second arc-shaped clamp. Then the operator places the measuring and verification instrument between the first arc-shaped clamp and the second arc-shaped clamp, and then slowly releases the pull rod. Under the elastic potential energy of the spring, the first arc-shaped clamp and the second arc-shaped clamp clamp the instrument between them. This method is simple to operate and facilitates the fixing of the instrument. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] Please refer to Figure 1-4 A metrological verification support includes a base 1. Support rods 3 are symmetrically mounted on the top surface of the base 1 about its center line. A crossbar 5 is positioned between the two support rods 3. A collar 6 is slidably fitted onto the surface of the crossbar 5. A hook 7 is provided at the bottom end of the collar 6. A fixing hole 9 is provided through the outer surface of the collar 6, and an adjustment hole 8 is provided through the surface of the crossbar 5. The collar 6 is fixed to the crossbar 5 via a connecting rod 10 passing through the fixing hole 9 and the adjustment hole 8. The combination of the adjustment hole 8, the fixing hole 9, and the connecting rod 10 facilitates the fixation of the collar 6 to the crossbar 5, ensuring the stability of the metrological verification instrument below the hook 7 and preventing interference caused by lateral swaying. During operation, the operator can slide the collar 6 to a designated position on the crossbar 5, align the fixing hole 9 with the adjustment hole 8, and then fix it through the fixing hole 9 and the adjustment hole 8 using the connecting rod 10. This method is simple to operate and facilitates the fixation of the collar 6.

[0023] In this embodiment: a placement box 4 is disposed above the base 1 between the two support rods 3. A clamping assembly is disposed inside the placement box 4, and a first arc-shaped clamping plate 12 and a second arc-shaped clamping plate 13 are disposed inside the clamping assembly. The surfaces of the first arc-shaped clamping plate 12 and the second arc-shaped clamping plate 13 are fixed to the inner wall of the placement box 4 by springs 11. Pull ropes 14 are disposed on the surfaces of the first arc-shaped clamping plate 12 and the second arc-shaped clamping plate 13, and pull rods 15 are disposed at the bottom ends of the pull ropes 14. The clamping assembly facilitates the clamping of metrological verification instruments. The clamping placement method allows the operator to pull the pull rope 14 downwards via the pull rod 15 during operation. The pull rope 14 then compresses the spring 11, causing the first arc-shaped clamp 12 and the second arc-shaped clamp 13 to separate. The operator then places the measuring instrument between the first arc-shaped clamp 12 and the second arc-shaped clamp 13 and slowly releases the pull rod 15. Under the elastic potential energy of the spring 11, the first arc-shaped clamp 12 and the second arc-shaped clamp 13 clamp and fix the instrument between them. This method is simple to operate and facilitates the fixation of the instrument.

[0024] In this embodiment, a through hole 16 is provided on the outer surface of the placement box 4. By providing the through hole 16, it is convenient to allow the pull rope 14 to pass through the through hole 16.

[0025] In this embodiment, multiple clamping components are provided, and the multiple clamping components are installed at equal intervals inside the placement box 4. By providing multiple clamping components, it is easier to increase the amount of fixation of the instrument.

[0026] In this embodiment, multiple adjustment holes 8 are provided, and the multiple adjustment holes 8 are equally spaced on the outer surface of the crossbar 5. By providing multiple adjustment holes 8, it is convenient to adjust the distance between two adjacent collars 6, and avoid interference between the devices on the hook 7.

[0027] In this embodiment, a rubber pad 2 is provided on the bottom surface of the base 1. By providing the rubber pad 2, the anti-slip performance of the base 1 can be improved, and the stability of the bracket can be improved when it is placed.

[0028] Working principle: During operation, the operator can slide the collar 6 to the designated position on the crossbar 5, then align the fixing hole 9 with the adjusting hole 8. The operator then uses the insertion rod 10 to pass through and fix the fixing hole 9 and the adjusting hole 8. This method is simple to operate and facilitates the fixing of the collar 6. By setting up a clamping component, it is easy to clamp and place the metrological verification instrument. During operation, the operator pulls the pull rope 14 downward by pulling the pull rod 15. Then, under the traction of the pull rope 14, the spring 11 is compressed, causing the first arc-shaped clamping plate 12 and the second arc-shaped clamping plate 13 to separate. The operator then places the metrological verification instrument between the first arc-shaped clamping plate 12 and the second arc-shaped clamping plate 13, and then slowly releases the pull rod 15. Under the elastic potential energy of the spring 11, the first arc-shaped clamping plate 12 and the second arc-shaped clamping plate 13 clamp and fix the instrument between them. This method is simple to operate and facilitates the fixing of the instrument.
