Abstract

The utility model discloses a temperature probe. The temperature probe comprises a metal annular frame with a bottom plate; the temperature probe also comprises an annular magnet, a temperature measuring probe, a pressure spring and a jump ring; the annular magnet is arranged on the periphery of the metal annular frame in a sleeved manner; a through hole is arranged in the middle of the bottom plate of the metal annular frame; the temperature measuring probe comprises a probe body and a connection column; the connection column is arranged on the inner end of the probe body; the probe body is arranged on one side of an inner cavity of the metal annular frame and is connected with the metal annular frame via the jump ring; a free end of the connection column is threaded through the through hole in a loose fit manner; and the pressure spring is sleeved on the connection column, one end of the pressure spring is pressed against the probe body and the other end is pressed against the bottom plate. The temperature probe can be easily connected with a to-be-tested object and is simple in structure and easy to manufacture, materials can be easily got, and the temperature probe is reusable.

Description

A kind of temp probe

Technical field

The utility model relates to a kind of for the thermometric temperature spy of metal material surface side device.

Background technology

Existing temp probe need be controlled with hand when measuring metallic materials surface temperature, easily causes temp probe contact bad with testee and cause and measure inaccurately, and easily causes human body to cause damage because of heat radiation.

Summary of the invention

The purpose of this utility model is to provide a kind of being convenient to be connected with testee and temp probe simple in structure.

In order to achieve the above object, the technical solution of the utility model is: a kind of temp probe, comprise the metal ring frame with base plate, ring-shaped magnet, temperature probe, holddown spring and jump ring, wherein ring-shaped magnet is sleeved on the periphery of metal ring frame, in the middle of the base plate of metal ring frame, there is through hole, temperature probe comprises sonde body and joint pin, joint pin is positioned at the inner of sonde body, sonde body is positioned at inner chamber one side of metal ring frame, and be connected with metal ring frame by jump ring, the free end loose fit ground of joint pin is through through hole, holddown spring is enclosed within on joint pin, and one end and sonde body offset, the other end and base plate offset.

The free end of described joint pin is connected with wire.

The outer face of described sonde body exceeds the open end of metal ring frame.

Described jump ring is two leaf springs, and sonde body is arranged symmetrically with relatively.

Adopt after said structure, owing to adopting ring-shaped magnet and holddown spring, therefore, in use, metal ring frame, is firmly connected with testee, without controlling with hand on the surface of tested metal material by ring-shaped magnet absorption; Meanwhile, temperature probe makes sonde body tightly be attached to the surface of tested metal material by holddown spring, and joint pin electrically connects to lead in corresponding instrument just can measure temperature.The utility model is simple in structure, is easy to make, and draws materials easily, can Reusability.

Fig. 2 is the A-A cut-open view of Fig. 1.

Embodiment

The embodiment providing below in conjunction with accompanying drawing is described in further detail the utility model.

As Fig. 1, shown in 2, a kind of temp probe of the present utility model, comprise the metal ring frame 1 with base plate 1-1, ring-shaped magnet 2, temperature probe 3, holddown spring 4 and jump ring 6, wherein ring-shaped magnet 2 is sleeved on the periphery of metal ring frame 1, in the middle of the base plate 1-1 of metal ring frame 1, there is through hole 1-1-1, temperature probe 3 comprises sonde body 3-1 and joint pin 3-2, joint pin 3-2 is positioned at the inner of sonde body 3-1, sonde body 3-1 is positioned at inner chamber 1-2 mono-side of metal ring frame 1, and be connected with metal ring frame 1 by jump ring 6, the free end loose fit ground of joint pin 3-2 is through through hole 1-1-1, holddown spring 4 is enclosed within on joint pin 3-2, and one end and sonde body 3-1 offset, the other end and base plate 1-1 offset.

As shown in Figure 2, for the ease of with Instrument connection, the free end of described joint pin 3-2 is connected with wire 5.

As shown in Figure 2, for the ease of contacting with testee, the outer face 3-1-1 of described sonde body 3-1 exceeds the open end 1-3 of metal ring frame 1.

As shown in Figure 1, 2, in order to make sonde body 3-1 motion steadily, described jump ring 6 is two leaf springs, and sonde body 3-1 is arranged symmetrically with relatively.

As shown in Figure 1, 2, described temperature probe 3 can be made with thermopair, thermal resistance and various thermally sensitive material, and for guaranteeing to measure accurately, wire 5 is selected the metal material matching with temperature probe 3 materials.
