Description

Technical Field

[0001] The utility model relates to the technical field of moisture determination, in particular to a sample tray fixing structure of a moisture determination instrument. Background Art

[0002] An instrument that can detect the moisture content in various organic and inorganic solids, liquids, gases and other samples is called a moisture meter;

[0003] In actual use, the existing moisture meter needs to place the sample tray on the top of the meter and then connect it with a pipe for measurement. However, the stability of the sample tray placed directly on the top of the meter is poor, and it is easy to accidentally touch the sample tray and cause it to fall and overturn, thus affecting the use effect of the device. Therefore, we propose a moisture meter sample tray fixing structure. Utility Model Content

[0004] The utility model aims to provide a sample tray fixing structure for a moisture meter, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sample tray fixing structure of a moisture meter, comprising a positioning cylinder, the positioning cylinder is fixed to the top of the moisture meter, the inner cavity of the positioning cylinder is fixed with a fixing plate, four sides of the inner cavity of the positioning cylinder are provided with clamping plates, through holes are opened on four sides of the top of the fixing plate, a movable plate is hinged in the through hole, the top of the movable plate is hinged by a connecting rod and the back side of the clamping plate, a lower pressure block is movably penetrated at the middle of the top of the fixing plate, the tail end of the lower pressure block is fixedly connected with a lifting plate, positioning rods are movably penetrated on both sides of the top of the lifting plate and the tail ends of the positioning rods are fixed to the bottom of the inner cavity of the positioning cylinder, a side wall of the tail end of the movable plate is fixedly connected with a cross plate, the cross plate is attached to the outer wall of the lower pressure block, the bottom of the lifting plate is fixedly connected with a first spring, and the tail end of the first spring is fixedly connected to the bottom of the inner cavity of the positioning cylinder.

[0006] By adopting the above technical solution, the sample tray is placed in the inner cavity of the positioning cylinder. At this time, the sample tray will drive the lower pressure block to descend, thereby pushing the horizontal plates on both sides, thereby driving the movable plate to rotate, so that the movable plate pushes the clamping plate to move inward, so that the sample tray can be clamped and positioned using four clamping plates, thereby ensuring the stability of the sample tray and avoiding tipping and falling.

[0007] As a preferred embodiment of the present utility model, a second spring is fixed to one side of the rear end of the movable plate, and the outer end of the second spring is fixedly connected to the inner wall of the positioning cylinder.

[0008] By adopting the above technical solution, when taking out the sample tray, the sample tray is lifted. At this time, the lower pressing block is not under pressure, so that it can be pushed up by the action of the first spring. At this time, the lower pressing block will release the cross plate, so that the movable plate can be reset under the action of the second spring, so that the clamping plate moves outward, making the operation of taking out the sample tray convenient and quick.

[0009] As a preferred embodiment of the present invention, a limiting block is fixed on one side wall of the movable plate corresponding to the rear end of the clamping plate.

[0010] By adopting the above technical solution and setting the limit block, the clamping plate can be limited to avoid excessive rotation of the clamping plate affecting the operation of placing the sample tray.

[0011] As a preferred embodiment of the utility model, an adaptive rubber pad is fixedly glued to the outer wall of the clamping plate.

[0012] By adopting the above technical solution and setting the rubber pad, wear can be avoided when clamping the sample disk, and at the same time, the clamping fit is high, thereby ensuring clamping stability.

[0013] As a preferred embodiment of the present invention, rubber blocks are fixed at the four corners of the bottom of the moisture meter.

[0014] By adopting the above technical solution and the provision of the rubber block, the overall placement and use stability of the device is high and sliding is avoided.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The sample tray fixing structure of the moisture analyzer of the technical solution of the present application is characterized in that the sample tray is placed in the inner cavity of the positioning cylinder, so that the sample tray drives the lower pressing block to descend, thereby pushing the horizontal plate to move outward, so that the end of the movable plate located on the upper side pushes the clamping plate to move, so that the sample tray can be automatically clamped and positioned by the four clamping plates, thereby ensuring the stability of the sample tray during use, and effectively avoiding the situation of falling and overturning;

[0017] By lifting the sample tray, the lower pressure block is lifted under the action of the first spring and the second spring, and the movable plate is reset at the same time, so that the clamping plate can automatically release the sample tray, making it convenient and quick to take out the sample tray after use, without the need to manually remove the positioning mechanism, further improving the convenience of use.

[0027] In actual use, the sample tray is placed in the inner cavity of the positioning cylinder 1. At this time, the sample tray drives the lower pressing block 31 to descend, thereby pushing the horizontal plates 36 on both sides, thereby driving the movable plate 13 to rotate, so that the movable plate 13 pushes the clamping plate 11 to move inward, so that the four clamping plates 11 can be used to clamp and position the sample tray, thereby ensuring the stability of the sample tray and avoiding the occurrence of tipping and falling.

[0028] Furthermore, the outer wall of the clamping plate 11 is fixedly glued with an adapted rubber pad 15. The provision of the rubber pad 15 can avoid wear when clamping the sample disk, and at the same time, the clamping fit is high, thereby ensuring the clamping stability;

[0029] Furthermore, rubber blocks 21 are fixed at the four corners of the bottom of the moisture meter 2. The arrangement of the rubber blocks 21 makes the overall placement and use of the device highly stable and prevents sliding.

When taking out the sample tray, the sample tray is pulled up, and the lower pressing block 31 is not pressed at this time, so that the lower pressing block 31 can be pushed up under the action of the first spring 34, and the lower pressing block 31 will release the cross plate 36, so that the movable plate 13 can be reset under the action of the second spring 37, so that the clamping plate 11 moves outward, so that the operation of taking out the sample tray is convenient and quick;

[0031] Furthermore, a limiting block 14 is fixed to one side wall of the movable plate 13 at the rear end of the clamping plate 11.

[0032] The implementation principle of the sample tray fixing structure of the moisture meter of the present application is as follows: in actual use, the sample tray is placed in the inner cavity of the positioning tube 1, at this time, the sample tray will drive the lower pressing block 31 to descend, thereby pushing the cross plates 36 on both sides, thereby driving the movable plate 13 to rotate, so that the movable plate 13 pushes the clamping plate 11 to move inward, so that the sample tray can be clamped and positioned by the four clamping plates 11, thereby ensuring the stability of the sample tray and avoiding the situation of tipping over and falling. When taking out the sample tray, the sample tray is lifted, and at this time the lower pressing block 31 is not pressed, so that the lower pressing block 31 can be lifted under the action of the first spring 34, and at this time the lower pressing block 31 will release the cross plate 36, so that under the action of the second spring 37, the movable plate 13 can be driven to reset, so that the clamping plate 11 moves outward, so that the operation of taking out the sample tray is convenient and quick.
