Abstract
The utility model discloses an improved structure of a thermocouple. The utility model is characterized in that a spring 6 is sheathed on a temperature sensing rod 4; the upper end of the spring 6 is screwed with a distribution board 3; the lower end of the spring is sheathed on the temperature sensing rod 4; the spring 6 causes the temperature sensing rod to have degrees of elasticity; the temperature sensing rod can tightly contact a protection sleeve 5 under any circumstances. The utility model modes overcomes the defect caused by a welding fixing mode of the existing thermocouple. The utility model can be assembled conveniently, and the accuracy of temperature measurement of the thermocouple can be enhanced.
Description
The utility model relates to a kind of improvement structure, especially combined structure of the temperature sensing rod of thermopair and distribution board of thermopair.
Thermopair is a kind of equipment that is widely used in thermometric.The formation of existing thermopair; as shown in Figure 1; mainly by terminal box A; lid B; distribution board C; temperature sensing rod D and thermal insulation casing E form; wherein; existing temperature sensing rod D is provided with an assembling base F with welding manner in its back-end; utilize this assembling base F fitted bolt G to be fixed in the below of distribution board C; temperature sensing rod D is stretched at downwards in the protective casing E; therefore; when temperature sensing rod D and distribution board C assembly, relatively waste time and energy; especially the warm contact H of temperature sensing rod D is located at the front end of barred body; in order to make accurate sensing temperature must become tight contact condition with protective casing E; with assembly cover F welding fixed form temperature sensing rod D and distribution board C are established as group; for this reason; must be very accurate on length is made; otherwise will produce the situation that warm contact H as shown in Figure 1 can't closely contact with protective casing E; and then cause the accurately problem of sensing temperature; also has varying environment condition along with the installing thermopair; the length of temperature sensing rod D and protective casing E has nothing in common with each other; under can't normalized situation, also make troubles to the producer.Based on the above-mentioned defective that existing thermopair exists, improve the eager desire that existing thermopair structure has become the producer and user.
The purpose of this utility model is to provide a kind of process structurally improved thermopair, and it can overcome the multinomial defective that existing thermopair brings because of the welding fixed form, can keep the various functions of existing thermopair again.
The utility model is to realize like this.On the basis of existing thermopair member; existing employing is established temperature sensing rod and distribution board group with assembling base welding fixed form; improvement is a sheathed spring on temperature sensing rod; the upper end of spring and distribution are spiraled to be established; collar is connected airtight on temperature sensing rod in the lower end; borrow the elasticity of spring to make temperature sensing rod have dilatability,, can guarantee the accurate sensing of temperature again to guarantee under any circumstance all tight contact protection sleeve pipes of energy.
Because the utility model is reasonable in design; practice shows; the thermopair that adopts the improvement structure to produce; a kind of thermopair that has more practicality is provided; because the effect of spring makes temperature sensing rod have retractility and can make its tight contact protection sleeve pipe; guaranteed the accurate sensing of temperature, simultaneously, also more convenient during assembly.Be subjected to the producer and user's welcome.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the insight structural map of existing thermopair
Fig. 2 is the constructing stereo figure between the utility model distribution board, spring and temperature sensing rod
Fig. 3 is an insight structural map of the present utility model
As Fig. 2; shown in Figure 3; the utility model is identical with existing thermopair all to be made up of main elements such as patching panel 1, lid 2, distribution board 3, temperature sensing rod 4 and protective casings 5; wherein; shrouding disc 2 spiral covers are on terminal box 1; distribution board 3 is established for 31 groups by bolt and is fixed in the terminal box 1, and protective casing 5 revolves is located at end under the terminal box 1.As shown in Figure 3; temperature sensing rod 4 is connected group by a spring 6 with distribution board 3 and establishes; the diameter of this spring 6 is greater than temperature sensing rod 4; the metal wire of its upper end is rolled into and is the thread end 61 that connects airtight shape; can cooperate the screw 32 of distribution board 3 lower ends to revolve mutually establishes; the metal wire of spring 6 lower ends be rolled into diameter little connect airtight shape collar end 62; but closely collar is on temperature sensing rod 4; can make temperature sensing rod 4 except can establishing with distribution board 3 mutual groups easily; and can make temperature sensing rod 4 have a dilatability because of spring 6; and the warm contact 41 that can make temperature sensing rod 4 front ends has under any assembled condition and all can closely contact shape for 5 one-tenth with protective casing, reaches the accurate sensing of guaranteeing temperature.
