Hole bottom surface be indent spherical surface 111, when spheroid 34 and the spherical surface 111 are tangent, the centre of sphere of the spherical surface 111 and spherical zone body 31
The centre of sphere be overlapped；Cone 33 is enclosed by the arcuate flanks of the different rounded bottom surface of two radiuses and an indent, cone 33
The diameter of one of bottom surface be less than the internal diameter of thermometer bulb 6, the diameter of another bottom surface of cone 33 and cylindrical body 32
Basal diameter is identical and is greater than the internal diameter of thermometer bulb 6；The bottom surface radius of cylindrical body 32 is less than the radius of spherical zone body 31, spherical zone body
31 radius is identical as the length of the semi-minor axis of ellipsoid 34；Spherical zone body 31, cylindrical body 32 and cone 33 are integrally formed；
In conjunction with Fig. 7, the bottom surface radius of cylindrical body 32 is less than the radius of spherical zone body 31, so that positioning body 3 is in first positioning hole
There is rotation space, i.e. positioning body 3 has the freedom degree circumferentially rotated along first positioning hole 11 and in the first positioning in 11
The freedom degree swung in hole 11, the hole bottom surface in conjunction with first positioning hole 11 are the spherical surface 111 of indent and the ball of the spherical surface 111
The characteristic of the centre of sphere three coincidence of the heart, the centre of sphere of spherical zone body 31, spheroid 34, when positioning body 3 generates in first positioning hole 11
(by gravity, and thermometer bulb 6 is inserted into down from 11 upper end of first positioning hole, therefore 34 meeting of spheroid when movement
It is pushed against on the hole bottom surface of first positioning hole 11), the position of three centre ofs sphere will not generate displacement relative to first positioning hole 11, by
Top is exerted oneself in being when connecing bubble, therefore one degree of freedom of the positioning body 3 on 11 axis of first positioning hole is limited and (be directed toward the
The freedom degree of the hole bottom surface of a positioning hole 11), and then ensure that when connecing bubble, thermometer bulb 6 will not sink and influence to connect bubble, together
When positioning body 3 can also using from first positioning hole 11 have swing freedom degree, and then guarantee thermometer bulb 6 not
While sinking, allow it that there is the freedom degree swung, so that thermometer tube body 7 and thermometer bulb 6 can when bonding
The problem of compensating unbalance stress brought by glass melting unevenness；Also with 52 energy of the decorative pearl on top of an official cap of the abutting device in blind hole 321
Enough guarantee the coaxial of positioning body 3 and first positioning hole 11, using the decorative pearl on top of an official cap 52 for pushing against device in cone 33 and first through hole 12,
So that thermometer bulb 6 be able to maintain it is coaxial with first positioning hole, due to the decorative pearl on top of an official cap 52 be it is circumferentially distributed, the decorative pearl on top of an official cap 52 with supported
The contact in tight face is Multi-contact in a plane, and then forms plane multi-point support, and the contact of cone 33 and thermometer bulb 6
It is circular contact (the port outer circle that the part that i.e. thermometer bulb 6 is contacted with cone 33 is thermometer bulb 6), therefore can also regards as
It is Multi-contact in a plane, is all using more in two planes for positioning body 3 and thermometer bulb 6
Point contact realizes positioning, and then guarantees coaxial；Furthermore this Multi-contact using in plane realizes positioning, due to being connecing for point
Touching, when one end of positioning body 3 or thermometer bulb 6 generate swing trend when, the plane multipoint positioning of the other end will not generate compared with
Big inhibition, plays the role of swing pivot instead；For convenience of understanding, for example, if thermometer bulb 6 is located at first through hole 12
The positioning at place does not utilize this point location of the decorative pearl on top of an official cap 52 instead of, is positioned using the face of similar axle sleeve, i.e. axle sleeve and thermometer bulb 6
Contact is face contact, has length in the axial direction of thermometer bulb 6, and this face contact positioning inherently defines thermometer
The swing of bubble 6, therefore will limit thermometer bulb 6 and generate swing close to the end of cone 33, and then cannot achieve thermometer bulb 6
The problem of swing goes compensation temperature meter tube body 7 and thermometer bulb 6 when bonding because of unbalance stress brought by glass melting unevenness；When
Thermometer bulb 6 can carry out adaptability movement by positioning body 3, and thermometer bulb 6 can generate fine motion and make its meeting and temperature gauge pipe
Body 7 is not coaxial, since the degree of glass melting unevenness is not very greatly, unevenly to cause thermometer bulb 6 to generate inclined
Poor and small, in addition thermometer bulb 6 and the coaxial required precision of thermometer tube body 7 be not high, and to the bonding effect of the two
It is required that it is high, therefore the little deviation of glass melting can't generate excessive coaxiality deviation to thermometer bulb 6；Thermometer bulb 6
It ensure that bonding accuracy with the coaxial of thermometer tube body 7 before bonding, and because unevenly leading to concentricity in bonding process
Deviation will not influence the use of thermometer, be just bonded using this deviation compensation, guarantee adhesive effect；In addition thermometer bulb
Gap between 6 and first positioning hole 11 also will limit it and deviate (gap width may be provided between 1-2mm), and then prevent temperature
Meter 6 transition shifts of bubble, and its hardness reduces in actual use, after glass melts, and positioning body 3 is also suffered from when swinging
The obstruction of the decorative pearl on top of an official cap 52, final temperature meter bubble 6 because glass melting it is uneven caused by offset be it is small, have no effect on thermometer
It uses (actual thermometer is of less demanding to the concentricity of thermometer bulb 6 and thermometer tube body 7).
Further, in conjunction with Fig. 5, since cone 33 is by the curved side of two radiuses different rounded bottom surfaces and an indent
Face encloses, therefore the slope of the side of cone 33 is variation, is stated for aspect, we retouch the cross section of cone 33
It states, as shown in figure 5, the slope of the side of cone 33 is gradually increased along the direction of the hole bottom surface far from first positioning hole 11, by
It in thermometer bulb 6 is set in cone 33, is arranged and is directly placed in a plane compared to by thermometer bulb 6 with more preferable
Locating effect, cone 33 has supporting role to the port of thermometer bulb 6, on the one hand since cone 33 is rotary body,
The side of cone 33 can position thermometer bulb 6, and combine with the abutting device in first through hole 12, so that
Thermometer bulb 6 and first positioning hole 11 are coaxial；On the other hand, using the slope variation of the side of cone 33, to thermometer bulb 6
Port forms protection, i.e., when thermometer bulb 6 is set in cone 33, according to force analysis, cone 33 can generate a direction
The axial component of thermometer bulb 6 and the component for being directed toward 6 radial direction of thermometer bulb, wherein being directed toward the radial component of thermometer bulb 6 can be right
Port generates distracted trend, can generate destruction to the port of thermometer bulb 6 if external force is excessive, therefore utilize the side of cone 33
The variation of the slope in face, when the port of thermometer bulb 6 is closer to spherical zone body 31, the component for being directed toward 6 radial direction of thermometer bulb is smaller,
And then damage of the reduction to thermometer bulb 6 while the positioning coaxial with first positioning hole 11 of raising thermometer bulb 6.
The abutting in abutting device, the second through-hole 21 as shown in Fig. 2, Fig. 3 and Fig. 6, respectively in first through hole 12
The structural schematic diagram of abutting device in device and blind hole 321；In view of thermometer tube body 7 and thermometer bulb 6 are to need to take
Out, therefore first through hole 12 and the second through-hole 21 need to the small decorative pearls on top of an official cap in the inner close to the port inner diameter of 2 axis of lower seat 1 or the seat of honour
52 outer diameter (as shown in figure 3, circle of dotted line is the extreme position of the decorative pearl on top of an official cap 52, the second through-hole 21 limits the decorative pearl on top of an official cap 52 and is detached from), to prevent
After thermometer tube body 7 and thermometer bulb 6 take out, the decorative pearl on top of an official cap 52 is detached from corresponding through-hole, the decorative pearl on top of an official cap 52 and corresponding first through hole 12 and
The inner wall of second through-hole 21 is tangent, and is pushed against on corresponding thermometer tube body 7 and thermometer bulb 6, while in order to facilitate the installation of,
Fixture nut 51, i.e. the first spring in first through hole 12 and the second through-hole 21 are respectively provided in first through hole 12 and the second through-hole 21
53 are pushed against in corresponding fixture nut 51；And positioning body 3 does not need to take out, therefore the nose end internal diameter of blind hole 321 can in it
The decorative pearl on top of an official cap 52 outer diameter it is identical, in conjunction with Fig. 7, when positioning body 3 swings to extreme position, i.e., cylindrical body 32 is against first positioning hole
When on 12 inner wall, the decorative pearl on top of an official cap 52 in blind hole 321 is located at the volume of maximum volume except blind hole 321 no more than the decorative pearl on top of an official cap 52
Half, i.e. at least half of the decorative pearl on top of an official cap 52 in the upper right corner or the lower left corner is located in blind hole 321 in Fig. 7, to guarantee the steady of positioning body 3
It is fixed；
Further, since the spherical zone body 31 on positioning body 3 is rotatablely connected with first positioning hole 11, above-mentioned guiding can be used
The fit tolerance of axis 4, also uses the fit tolerance of f8, and cooperates lubricating grease；Second location hole and thermometer tube body 7 use gap
Cooperation realizes coaxial, second location hole inner wall setting anti-slip rubber layer, to guarantee that thermometer tube body 7 cannot using device is pushed against
It moves freely.So that thermometer tube body 7, which can generate pushing, tries hard to keep and demonstrate,proves bonding effect when the pressing seat of honour 2；Additionally due in not
With hole in push against that the object that device pushes against is different, therefore 52 pairs of abutting power generated by the face of abutting of the decorative pearl on top of an official cap also not phase at three
Together, the abutting power that wherein decorative pearl on top of an official cap 52 in the decorative pearl on top of an official cap 52 and first through hole 12 in blind hole 321 generates is smaller, when flame keeps glass molten
After change, thermometer tube body 7 is acted on thermometer bulb 6, is enabled in the first spring 53 and the first through hole 12 in blind hole 321
The first spring 53 elastic force generate deformation so that thermometer bulb 6 generate fine motion compensation glass melting unevenness bring ask
Topic, while the abutting power that the decorative pearl on top of an official cap 52 of blind hole 321 generates wants that the frictional force of spherical zone body 31 Yu first positioning hole 11 can be overcome, into
And enable positioning body 3 generate swing after self-return；The elastic force of the first spring 53 in second through-hole 21 is greater than separately
The elastic force of outer two the first springs 53, can specifically go to set according to the actual situation.
In use, first shorter thermometer bulb 6 is inserted into first positioning hole 11, positioning body 3 and first through hole 12 are utilized
The interior decorative pearl on top of an official cap 52 makes thermometer bulb 6 and first positioning hole 11 coaxial, and thermometer tube body 7 is then being inserted in the second of the seat of honour 2
Positioning hole, when grafting, need first to press the seat of honour 2, so that the seat of honour 2 moves down one end distance, keep the seat of honour 2 static at this time, then press
Thermometer tube body 7 is pressed then to unclamp again the seat of honour 2, the seat of honour 2 is in the second bullet so that thermometer tube body 7 is adjacent on thermometer bulb 6
