Description

Test tube clamp for liquid nitrogen tank

Technical Field

The utility model relates to the technical field of liquid nitrogen tanks, in particular to a test tube clamp for a liquid nitrogen tank.

Background

The liquid nitrogen tank can be generally divided into a liquid nitrogen storage tank and a liquid nitrogen transport tank. The storage tank is mainly used for standing storage of indoor liquid nitrogen and is not suitable for long-distance transportation in a working state; the liquid nitrogen transport tank is specially designed to be shockproof in order to meet the transport conditions. Besides standing for storage, the liquid nitrogen storage container can be used for transportation in a liquid nitrogen filling state, and severe collision and vibration are avoided. The liquid nitrogen storage tank is generally large, and the test tube is difficult to take out after being placed, so that the liquid nitrogen storage tank needs to be assisted by tools. The specifications of the liquid nitrogen tanks are different, and test tube clamps with different lengths are required.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a test tube clamp for a liquid nitrogen tank.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a test tube clamp for liquid nitrogen container, includes clamp holder, fixture and handle, the platform is installed to clamp holder one end, and other end fixed mounting has the handle, the platform one end of keeping away from of clamp holder is provided with the threaded rod, the inside threaded hole that offers of handle, threaded rod and threaded hole screw-thread fit, clamping structure is used for the centre gripping test tube.

Further, fixture includes arm, rubber pad and button, the arm inboard is provided with the rubber pad, and the rubber pad can play the effect of increasing friction power, protects the test tube simultaneously not with arm direct contact, the rubber pad is fixed inboard at the arm through gluing, button and arm signal connection, button installation handle surface can control the arm through the button and snatch the test tube, and the arm is installed in platform one side, arm and platform mutually perpendicular.

Further, arm internally mounted has pressure to experience the unit, and pressure experiences the unit and makes the arm can not lead to the test tube to break with excessive force when snatching the test tube.

Furthermore, the surface of the rubber pad is provided with latticed stripes, and the latticed stripes are used for further increasing the friction force.

Furthermore, the length of the clamp handle and the handle in the storage state is mm, and the length of the clamp handle and the handle in the complete unfolding state is mm.

Furthermore, the tail end of the handle is provided with a protective sleeve, and the protective sleeve has an anti-skidding function.

Further, the protective sheath material is rubber, and the protective sheath surface has seted up the rectangle recess, the recess is deep 2mm wide 3 mm.

The utility model has the beneficial effects that: the adjustable clamp holder that proposes through this scheme is applicable to the liquid nitrogen container of the different degree of depth, has solved the problem that the test tube in the liquid nitrogen container is difficult to take out, and the test tube centre gripping is firm simultaneously.

FIG. 2 is a schematic view of the internal structure of a grip of a test tube clamp for a liquid nitrogen tank according to the present invention.

In the figure: 1 clamp holder, 2 fixture, 21 arm, 22 rubber pads, 23 buttons, 3 handholds, 4 platforms, 5 threaded rods, 6 screw holes, 7 protective sheaths, 8 grooves.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In this embodiment, referring to fig. 1-2, a test tube clamp for liquid nitrogen container, including clamp holder 1, fixture 2 and handle 3, platform 4 is installed to clamp holder 1 one end, other end fixed mounting has handle 3, the platform 4 one end of keeping away from of clamp holder 1 is provided with threaded

rod

5, 3 inside threaded hole 6 of seting up of handle, threaded rod 5 and threaded hole 6 screw-thread fit, when the liquid nitrogen container is less, can take threaded rod 5 into threaded hole 6 completely, when the liquid nitrogen container is great, threaded rod 5 back out the length of extension clamp holder 1, 2mm long when clamp holder 1 is in the state of accomodating with handle 3, 3mm long are unfolded completely with handle 1, clamping structure 2 is used for the centre gripping test tube.

Further, fixture 2 includes arm 21, rubber pad 22 and button 23, arm 21 inboard is provided with rubber pad 22, rubber pad 22 is fixed in arm 21 inboard through gluing, button 23 and arm 21 signal of telecommunication are connected, 3 surfaces of button 23 installation handle, 21 internally mounted of arm has the pressure to experience the unit, the pressure experiences the unit and makes arm 21 can not lead to the test tube to break hard excessively when snatching the test tube, rubber pad 22 surface is provided with latticed stripe, latticed stripe is used for further increasing frictional force.
