Abstract

The utility model relates to a quick-assembling-disassembling electric thermocouple, which comprises a junction box component 1, a protective tube 2, a connecting key 4, a connecting body component 5 and an electric thermocouple component 6. The connecting body component 5 is a means composed of a base 7 and a pin plate 8 and can rotate surrounding a hinged shaft 9 connected to the base 7 and the pin plate 8 to open and close; the center of a combining surface is provided with semicircular slots 14; a diameter of a circular slot formed by the two semicircles after gathering is larger than that of the electric thermocouple component. A handle of the pin plate is slightly pressed in a counterclockwise direction, the pin plate rotates surrounding the hinged shaft, the base and the pin plate stretch, and the electric thermocouple component can be rapidly drawn out or inserted at that time. The handle of the pin plate is slightly pushed in a clockwise direction, the base and the pin plate gather, and the electric thermocouple component is tightly clamped by the semicircular slots and a damping reed; the electric thermocouple component can not be drawn out or inserted if the handle of the pin plate is not pushed. The utility model has the advantages of simple structure and simple and rapid operation. The utility model is suitable to be used in temperature measuring occasions harmful to human bodies, such as nuclear industry, etc.

Description

The fast assembling-disassembling thermopair

Technical field

The utility model relates to sensor, especially a kind of thermopair of energy fast assembling-disassembling.

Background technology

Thermopair is the sensor that is used to measure temperature, by junction box assembly, and protection tube, connecting key, connector assembly and thermopair subassembly are formed.During use, the connector assembly is fixed on the measured object, and the inner end is deep into testee measuring point place, and body surface is fixed in the outer end.Connecting key is locked in the thermopair subassembly on the measuring point by the connector assembly.Because the thermopair subassembly belongs to consumable accessory, need often overhaul, safeguards and change, therefore, it is inevitable constantly the thermopair subassembly being extracted out from connecting key, being inserted.Each operation all needs operating personnel to be in the action, the cost certain hour.This chain connects form and there is no big harm for conventional thermometric occasions such as electric power, chemical industry, water conservancies, but nuclear industry etc. has radioactive contamination and harmful thermometric occasion is improper if be used for.Meetings such as radioactive ray leak pollute operating environment, the injury operating personnel.Need this moment can fast assembling-disassembling and be suitable for the thermometric device of Robot actions could be competent at a job.

Summary of the invention

The purpose of this utility model provides a kind of energy fast assembling-disassembling and is suitable for the temperature thermocouple of Robot actions, to adapt to the request for utilization of thermometric under the environment such as radioactive contamination is arranged.

Said thermopair comprises junction box assembly 1, protection tube 2, connecting key 4, connector assembly 5 and thermocouple assembly 6, it is characterized in that: said connector assembly 5 be one by can rotating and the member of folding that 8 liang of parts of pedestal 7 and pin plate constitute around the hinge 9 that is connected them, centre at its face that is harmonious is provided with semicircle slotted eye 14, and the diameter of the round-formed round slot bore of two halves is big than the thermopair subassembly thus after closing up, in order to successfully to extract or to insert the thermopair subassembly out; Pin plate is provided with an arc stopper slot 12, is inserted with the register pin 11 that can slide in groove in the stopper slot, and register pin is hinged on hinge 10 by its pin rod; On the pedestal of a relative side with hinge, pin plate outer wall damping reed 13 is housed, an end of this reed is fixed on the pedestal, and the other end is pressed on the pin plate.

Counterclockwise light pad plate handle, pin plate promptly rotates around hinge, and pedestal, pin plate open, and can fast promptly extract the thermopair subassembly or insert out this moment; Clockwise direction is touched the pin plate handle, and pedestal, pin plate close up, and semicircle slotted eye and damping reed clamp the thermopair subassembly, just can not extract or insert the thermopair subassembly out if do not promote the pin plate handle.The utility model has advantage simple in structure, simple and efficient to handle, is suitable for using nuclear industry etc. has the thermometric occasion of harm to human body under.
