Description

A hanging auxiliary device for water bath calibration

Technical Field

The utility model relates to the technical field of water bath equipment, in particular to a hanging type auxiliary device for water bath calibration.

Background

The water bath is a common temperature heating device in the laboratory, calibrated as per protocol using a standard platinum resistance thermometer. The water bath apparatus presents a rectangular or circular working area. Meanwhile, the platinum resistance thermometer is slow in stability time and needs to be suspended in liquid, and according to regulations, multipoint measurement needs to be carried out on the same plane in the liquid. In actual work, the handheld instrument cannot ensure the consistency of the measurement position and the depth, and the operator is easily fatigued by keeping one posture for a long time. In addition, when the temperature is high, high temperature or water vapor may present a safety hazard to the hands.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems caused by manual handheld operation of the existing water bath calibration, and provides a hanging type auxiliary device for the water bath calibration, which comprises a platinum resistance thermometer; a base; the fixture is arranged on a sliding block and used for clamping the platinum resistance thermometer; the sliding block is connected with the clamp and is arranged on a sliding arm; the sliding arm is provided with a sliding chute, the sliding block can move along the sliding chute, and the tail end of the sliding arm is connected with the base through a rotating shaft; the hook is arranged on the base.

The utility model also has the following preferable technical scheme:

1. an adjusting knob is arranged on the clamp.

2. Be equipped with the side spout on the base, the couple set up in the side spout, the couple can remove along the side spout.

Compared with the prior art, the utility model has the advantages that:

1. the platinum resistance thermometer can be fixed in a working area, a standard device does not need to be held by a person, the horizontal depth of a measuring point is guaranteed to be consistent, and potential safety hazards are avoided;

2. the device can be suitable for circular or rectangular water bath equipment and has wide application range;

3. a fan-shaped movement of the platinum resistor in the working area in a plane can be realized.

Detailed Description

The present invention is further described below in conjunction with the following drawings, the structure and principle of which will be apparent to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1 and 2, the utility model relates to a hanging type auxiliary device for water bath calibration, which comprises a platinum resistance thermometer, a base, a clamp, a slide block, a sliding arm and a hook, wherein the clamp is arranged on the slide block and used for clamping the platinum resistance thermometer; the sliding block is connected with the clamp and is arranged on a sliding arm; the sliding arm is provided with a sliding chute, the sliding block can move along the sliding chute, and the tail end of the sliding arm is connected with the base through a rotating shaft; the hook is arranged on the base.

In a preferred embodiment, the clamp is further provided with an adjusting knob, the base is provided with a side sliding groove, the hook is arranged in the side sliding groove, and the hook can move along the side sliding groove.

The structure and the function of each part are as follows:

1. adjusting a knob: the angle and the force of the clamp are changed by rotating so as to meet the requirements of different platinum resistance thermometers;

2. a clamp: the platinum resistance thermometer is used for fixing the platinum resistance thermometer, and the angle can be changed by adjusting a knob;

3. a slide block: the clamp is used for fixing the clamp and can move along the direction of the moving arm;

4. a moving arm: the sliding block is used for fixing the sliding block and can rotate 120 degrees by taking the rotating shaft as a circle center;

5. a chute: the device is used for guiding the moving track of the sliding block;

6. a base: the device is used for fixing the movable arm and connecting all parts of the device;

7. hooking: the base is hung on the inner wall of the water bath equipment, and the tail end of the base is required to be propped against the inner wall to keep the device stable;

8. rotation axis: the positioning device is used for positioning the rotating circle center of the moving arm;

9. side chute: the device is used for guiding the moving track of the hook so as to adapt to the inner walls of devices with different thicknesses.

The specific working process of the utility model is as follows:

during calibration, the hook is adjusted to adapt to the thickness of the inner wall of the water bath equipment, and the tail end of the base abuts against the inner wall of the water bath working area. The platinum resistance thermometer is clamped by a clamp and adjusted to a proper height, and the reading can be carried out after the reading is stable. When the position of the clamp needing to be adjusted on the horizontal plane of the whole working area can be adjusted by moving the sliding block or rotating the moving arm, if the distance is not enough, the hook can be loosened, and a proper position is found to fix the device again.

In a specific embodiment, the cover of the water bath is removed, the water bath working area is circular, and the position of the hook is adjusted and fixed so that the device just hangs on the inner wall of the equipment, and the end of the device base can be pressed against the inner wall, thereby keeping the device stable. The platinum resistance thermometer was extended into a fixed position in the liquid and the knob was adjusted to be grasped by the clamp. The water bath was started and after it reached the set temperature and stabilized, the reading of the platinum resistance thermometer was read. Then need to carry out the temperature measurement to other positions, rotate the removal arm, remove the slider again, can make platinum resistance thermometer fix a position this another position on plane, wait to carry out the reading again after stabilizing. Since the working area of the water bath is not large in the example, the fan-shaped moving area of the device can cover the working plane, so that the device does not need to be installed again by loosening the hook. And executing the step for multiple times, and calculating according to the measured value to finish the calibration.
