Description

Technical Field

[0001] The utility model relates to the technical field of measuring mechanisms, in particular to a high-stability soft fruit stem force measuring mechanism. Background Art

[0002] When measuring the hardness, brittleness, stickiness, elasticity and other indicators of fruit stems, a texture analyzer is usually used. A texture analyzer is an instrument that evaluates the texture characteristics of a substance by simulating the sense of touch of human senses. It is used to measure and analyze the texture characteristics of materials. It analyzes the mechanical properties of materials through the force and displacement sensors it carries, and is widely used in materials, medicine, agriculture and other fields.

[0003] In the texture measurement of fruits, especially the measurement of fruit stem force, the existing clamping equipment of texture analyzers is originally designed for mechanical materials, such as metals, plastics and textiles. These materials are relatively hard and can withstand large clamping and operating forces. However, when clamping soft fruits, excessive local pressure will be applied to the fruits, resulting in peel damage and flesh damage, thus affecting the test results. Therefore, a high-stability soft fruit stem force measurement mechanism is proposed to address the above problems. Utility Model Content

[0007] Preferably, angle rulers for checking angles are fixedly connected to both sides of the surface of the support column, and fixing screws are provided between the support column and the bottom of the fixing piece.

[0008] Preferably, rubber gaskets are provided on the inner sides of the sliding member and the fixing member, and buckles are provided on the outer sides of the rubber gaskets at the fixing member.

[0009] Preferably, the buckle comprises a positioning block, a fixing block and an elastic block; the rubber gasket is fixedly connected to the positioning block; and the top of the positioning block is fixedly connected to the elastic block which is arranged in a hemispherical shape.

[0010] Preferably, fixing blocks with raised tops are fixedly connected to both sides of the fixing member, and the raised parts of the fixing blocks are tightly fitted with the elastic blocks.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by arranging the texture analyzer body, the upper clamping device, the bottom plate, the tray, the handle nut, the support column and the lower clamping device, the handle nut can effectively fix the tray and the bottom plate with a stepped groove structure on the surface, making the installation and use process simpler and more convenient, and the measuring device can be installed in both directions to achieve an angle adjustment from 0° to 180°, and an angle ruler with a marking range of 0° to 90° set on the surface of the support column allows the user to adjust the angle of the clamping device as needed, and the support column and the lower clamping device are fixed by fixing screws, providing a stable test platform, and the lower The fixings and sliding parts of the clamping device are designed with symmetrical structures to ensure that the pressure can be evenly distributed when clamping the fruit to avoid uneven local squeezing of the fruit.

By setting a lower clamping device 8 with a movable structure on one side and symmetrically arranged with the fixed structure, the pressure can be evenly distributed when the fruit is clamped to avoid uneven local squeezing. By setting a partially detachable rubber gasket 82, it is easy to replace after wear.

[0023] Angle rulers 7 for checking angles are fixedly connected on both sides of the surface of the support column 6, and fixing screws are provided between the support column 6 and the bottom of the fixing member 81, which is convenient for the accurate rotation of the lower clamping device 8 and the fixation after rotation; rubber gaskets 82 are provided on the inner sides of the sliding member 85 and the fixing member 81, and buckles 83 are provided on the outer sides of the rubber gasket 82 at the fixing member 81, so that the fruit is not easily damaged during clamping, and the rubber gasket 82 at the fixing member 81 can be replaced after wear; the buckle 83 includes a positioning block 831, a fixing block 832 and an elastic block 833, the rubber gasket 82 and the positioning block 831 are fixedly connected, and the top of the positioning block 831 is fixedly connected to the elastic block 833 set in a hemispherical shape, which is convenient for the positioning and installation of the rubber gasket 82 at the fixing member 81; fixed blocks 832 with a convex top are fixedly connected on both sides of the fixing member 81, and the convex part of the fixing block 832 is tightly fitted with the elastic block 833, which is convenient for the fixation of the rubber gasket 82 at the fixing member 81 after installation.

[0024] Working process: When using the high-stability soft fruit stem force measurement mechanism, first place the texture analyzer body 1 in a suitable position, place the bottom plate 3 driving the support column 6 on the surface of the tray 4, fix the position of the bottom plate 3 by inserting and rotating the handle nut 5, and then place the object to be measured in the clamping block of the upper clamping device 2, and simply fix the measured object by the bolt of the upper clamping device 2, and then rotate the stop bolt at the sliding member 85 to adjust the position of the sliding member 85 to move it to the fixed plate 84. After moving to a suitable position, the fixing member 81 and the sliding member 85 cooperate to clamp the measured object, and then tighten the stop bolt to fix the sliding member 85. At this time, the upper clamping device 2 and the lower clamping device 8 clamp and measure the measured object. When the angle of the lower clamping device 8 needs to be adjusted, the user loosens the support The fixing screws at the column 6 are used to rotate the lower clamping device 8.

By setting a lower clamping device 8 with a movable structure on one side and symmetrically arranged with the fixed structure, the pressure can be evenly distributed when the fruit is clamped to avoid uneven local squeezing. By setting a partially detachable rubber gasket 82, it is easy to replace after being worn.
