Description

[Detailed description of the invention] The present invention relates to a stand that supports evaporators and other equipment for physical and chemical experiments, small-scale industrial use, etc. and whose height is freely adjustable. An upper column is fitted to the outside of the upper column so that it can be slid up and down, and a supporting part such as an evaporator is mounted on the upper column. A pair of tightening protrusions are provided at both ends of the part facing outward, and a notch through which the protruding pieces can pass is provided at the lower part of the fastener support, which has a cylindrical shape larger than the outer diameter of the upper column. The protruding piece is pushed outward and the tightening ring is fitted to the lower part of the fastener support, the tightening ring is attached to the outer periphery of the lower end of the lower column, the fastener support is attached to the lower part of the upper column, A fastener that fits into the fastener support, and has a protrusion on the outside of the fastener support at the top of the notch, and a clamping piece that presses the tightening protrusion of the fastening ring from both sides. is pivotally attached to the protrusion of the support so as to be vertically rotatable.

An example of implementing the present invention will be described below with reference to the drawings.

A gas pressure spring 2, a lower column 3 fitted on the outside of the spring 2, and an upper column 4 fitted on the outside so that it can slide up and down are erected on the base 1, and a support 5 such as an evaporator is mounted on the upper column 4. establish.

The lower end 21 of the plunger of the gas pressure spring 2 penetrates into the cylindrical base body 22 and is supported by a ring 24 via a washer 23, the gas pressure spring 2 is inserted into the lower column 3, and the base body 22 is inserted into the lower part of the lower column 3. Then, the lower part is fitted to the base 1 and fixed with screws 11.

A tightening ring 6 is provided around the lower column 3 on the base 1.
mate. This tightening ring 6 has an expandable and retractable cutout ring shape with an inner diameter larger than that of the lower column 3, and a pair of tightening protrusions 61 and 62 are provided outward in parallel at both ends of the cutout. It is preferable that the one end portions 63 and 64 be bent to have a tapered shape.

A cylindrical fastener support 7 is fitted onto the outer periphery of the fastening ring 6 that is in contact with the lower part of the upper column 4 and its lower end. This support body 7 has a stepped part 70 for receiving the lower end of the upper column 4 at the middle part of the inner circumference, and an inner circumferential protrusion 71 for receiving the tightening ring 6 at the lower end, and one place on the periphery for tightening the tightening ring 6. A downward notch 72 through which the protruding pieces 61 and 62 can pass is provided, and a protruding portion 73 and a pin hole 74 passing through the cutout 72 are provided in the upper part thereof, and the fastener 8 is attached thereto.

The fastener 8 has a gripping piece 80, pinching pieces 81, 82 provided on both sides of the gripping piece 80, and a bottom piece 83 connecting these two pieces. A pin hole 84 is provided at the end of the protrusion 73, and a pin 75 is provided in the pin hole 74 of the protrusion 73.
is inserted so that the fastener 8 can be rotated in the vertical direction, and the end of the triangle is rounded to facilitate rotation, and the oblique side 86 following the roundness allows downward rotation. The tightening projections 61 and 62 are tightly sandwiched between the pinching pieces 81 and 82, and the tightening ring 6 is tightened to the lower column 3 and stopped. The above tightening protruding piece 6
1 and 62 are tapered so that they can easily enter between the pinching pieces 81 and 82 of the fastener 8.

Note that 9 in the figure is a sliding sleeve inserted between the lower column 3 and the upper column 4.

In the stand constructed as described above, the upper column 4 can be raised from the solid line position in FIG. 1 as shown by the chain line and stopped at any position. That is, the fastener 8 is
When the clamping pieces 81 and 82 are rotated upward from the lower position shown by the solid line in the figure as shown by the chain line, the clamping ring 6
Since the fastening ring 6 loosens when separated from the protruding pieces 61 and 62, in this state, the fastener support 7 is slid up together with the fastening ring 6 to an arbitrary height on the lower column 3, and then the fastener 8 is moved downward. When rotated, the protruding pieces 61 and 62 of the tightening ring 6 are clamped between the pinching pieces 81 and 82 and tightened, so the tightening ring 6 is fixed around the lower column 3 and the upper column 4 is tightened.
is secured in the raised position.

In the present invention, as described above, the tightening ring 6 loosens when the fastener 8 rotates upward and tightens when the fastener 8 rotates downward, and the upper column can be raised and lowered and stopped at any position easily and reliably.
The evaporator and other equipment can be left attached to the support part of the evaporator without any problems, and if the repulsive force of the built-in gas pressure spring and the weight of the evaporator etc. are balanced, it can be operated without requiring much force, which is a practical benefit. It's a huge amount.
