Description

Technical Field

[0001] The utility model relates to the technical field of test tube stands, in particular to an anti-dumping test tube stand. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated. Test tubes are divided into ordinary test tubes, supported test tubes, centrifugal test tubes, etc. During use, test tubes need to be used with test tube racks, which are the most basic experimental instruments in chemical laboratories for placing and drying test tubes.

[0003] Although the existing test tube rack can place test tubes for centralized observation during use, if the test tube rack shakes when the test tubes are placed on the test tube rack, the test tubes may slip off the test tube rack, or even the test tube rack may fall over as a whole, so an anti-falling test tube stand is needed.

A fixing assembly is arranged above the bottom plate, and a plurality of bottom support assemblies are arranged on the upper surface of the bottom plate.

[0008] The fixing assembly includes a bottom sleeve fixedly connected to the upper surface of the bottom plate, a slot opened on the surface of the bottom sleeve, and an active block movably connected in the slot. The height of the cross frame can be adjusted by setting the bottom sleeve, the slot and the active block.

[0009] Preferably, a support rod is fixedly connected to one side surface of the movable block, and a cross frame is fixedly connected to the upper end of the support rod, and the test tube can be placed by setting the cross frame.

[0010] Preferably, the fixing assembly further comprises an arc groove formed on the inner wall surface of the cross frame and a pull rod extending through and movably connected to the side surface of the cross frame. The provision of the arc groove facilitates the limited placement of the test tube.

[0011] Preferably, one end of the pull rod is fixedly connected to an arc-shaped clamping plate, and both sides of the surface of the arc-shaped clamping plate are fixedly connected to telescopic springs. Through the arrangement of the pull rod, the arc-shaped clamping plate and the telescopic spring, the test tube can be clamped and limited.

[0012] Preferably, the base support assembly includes a support sleeve fixedly connected to the upper surface of the base plate, a buffer spring fixedly connected to the inside of the support sleeve, and a movable rod fixedly connected to the upper end of the buffer spring. By arranging the support sleeve, the buffer spring and the movable rod, the bottom end of the lifted test tube can be buffered.

[0013] Preferably, the upper end of the movable rod is fixedly connected to a supporting plate, and the upper surface of the supporting plate is fixedly connected to an arc-shaped drag pad. The arrangement of the supporting plate and the arc-shaped drag pad enables the bottom end of the test tube to be lifted.

[0014] Preferably, the base support assembly further comprises a support bar fixedly connected to the upper surface of the arc-shaped drag pad and a limiting ring fixedly connected to the upper end of the support bar.
