Detailed Embodiments

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "front", "upper", "lower", "left", "right", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] The following will further illustrate the present utility model in conjunction with the attached Figures 1 - 4 drawings.

[0023] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a metering instrument detection test bench.

[0024] In the specific technical solution, it includes a storage box 1, a positioning bottom plate 2 and a detection top plate 3. The positioning bottom plate 2 is located at the bottom of the storage box 1, and the detection top plate 3 is located at the top of the storage box 1. Installation grooves are opened on both sides of the storage box 1, and control cylinders 4 are installed in the installation grooves. The detection top plate 3 is installed at one end of the control cylinder 4. The control cylinder 4 can drive the detection top plate 3 to move to facilitate the start of the detection test. A storage groove 5 is opened in the storage box 1, a placement opening 6 is opened in the detection top plate 3, and a detection component 7 for detecting the length of the metering instrument is arranged in the placement opening 6. A detection opening 11 is opened at the bottom of the placement opening 6.

[0025] Referring to Figure 1 - and Figure 3 As shown, the detection component 7 includes a mounting head 701, a detection rod 702, a pressure detector 703 and a limiting spring 704. The mounting head 701 is clamped in the placement opening 6. The detection rod 702 is installed below the mounting head 701 and its bottom is clamped in the detection opening 11. The pressure detector 703 is installed in the mounting head 701 and the detection probe at the bottom is installed at the bottom of the detection rod 702. The limiting spring 704 is installed between the mounting head 701 and the inner wall of the placement opening 6. By means of the limiting spring 704, the positions of the detection rod 702 and the mounting head 701 after detection can be controlled, and it is convenient to judge whether the length of the metering instrument meets the product specifications by observing the change of the reading of the pressure detector 703.

[0026] Referring to Figure 2 andFigure 3 As shown, an indicating ring 8 is engraved on the outer side wall of the mounting head 701. The indicating ring 8 is located inside the top of the placement opening 6. Whether the indicating ring 8 is exposed after observation and detection can be used to judge whether the length of the measuring instrument is too long.

[0027] Refer to Figure 3 and Figure 4 As shown, a clamping groove 9 is formed at the top of the positioning base plate 2, and the bottom of the accommodating box 1 is clamped in the clamping groove 9, which can ensure the stable setting of the accommodating box 1.

[0028] A bottom accommodating groove 10 is formed at the top of the clamping groove 9. The placement opening 6, the detection opening 11 and the bottom accommodating groove 10 are all arranged on the same vertical plane.

[0029] For those skilled in the art to fully understand the technical solution, the following is an overall overview of this application:

[0030] When the utility model is in use, first, the bottom of the measuring instrument is fixedly placed in the bottom accommodating groove 10, then the accommodating box 1 is placed into the positioning base plate 2 and the measuring instrument is placed in the accommodating groove 5. After that, the control oil cylinder 4 is connected to an external power supply and the control oil cylinder 4 is adjusted to retract. Therefore, the detection top plate 3 can be pulled to the top of the accommodating box 1. For those with qualified length specifications, a pressure indication will appear on the pressure detector 703 above it. For those with too short length, no pressure indication will appear on the pressure detector 703 above it. For those with too long length, the mounting head 701 above it can be pushed upward by the recording instrument and the limiting spring 704 can be stretched. After that, the indicating ring 8 can be exposed and observed.
