The plurality of clamping mechanisms 330 are arranged in parallel and at intervals along the vertical direction inside the fixed cylinder 320, and the adjusting bolt 310 is screwed to the top of the fixed cylinder 320 to adjust a plurality of clamping plates on the clamping mechanism 330, so that the clamping assembly 300 can clamp and cure ceramic pipe sheaths with different diameters.

[0026] When curing the ceramic protection sleeve outside the sampling probe, the production personnel will put the ceramic protection sleeve to be cured on the outside of the clamping assembly 300 arranged on the cover plate 200, so that several clamping mechanisms 330 on the clamping assembly 300 clamp and fix the ceramic protection sleeves with different diameters under the rotation of the adjusting bolt 310. After the clamped and fixed ceramic protection sleeve is placed into the curing cylinder 100, the connection port on the cover plate 200 is clamped and connected with the connection terminal 150 arranged on the curing cylinder 100, so that the self-limiting temperature heating tape electrically connected to the connection terminal 150 performs constant temperature heating, so that the internal cavity of the curing cylinder 100 remains at a constant temperature, so that the ceramic protection sleeve is cured at a constant temperature in the curing cylinder 100, thereby improving the curing production efficiency and production quality of the sampling probe ceramic protection sleeve by the curing device.

[0027] As a preferred embodiment, please refer to Figure 1 and Figure 2 , the heat insulation layer 120 is foam heat insulation cotton, which prevents the temperature flow rate after the heating plate 130 is heated. The heating plate 130 has the material characteristics of a self-limiting temperature heating tape and can automatically control the temperature of the heating device to ensure the constant temperature condition during the curing process. The heat conducting plate 140 is made of metal and is used to quickly conduct the heat after the heating plate 130 is heated into the heat conducting plate 140, so that the inner cavity of the heat conducting plate 140 maintains a constant temperature, thereby ensuring the curing stability of the ceramic protection sleeve during the curing process.

The connection terminal 150 is electrically connected to the heating plate 130, so that after the connection port on the cover plate 200 is clamped and connected with the connection terminal 150 on the curing cylinder 100, the heating plate 130 on the curing cylinder 100 is started, so as to heat and keep warm the inside of the fixing cylinder 320.

[0029] As a preferred embodiment, please refer to Figure 4 and Figure 5, the clamping mechanism 330 includes a plurality of clamping blocks 331, a plurality of connecting rods 332, a plurality of linkage rods 333 and two connecting plates 334. The two connecting plates 334 are fixedly installed on the adjusting bolt 310 in a side-by-side manner. An arc-shaped chute 3341 is provided on the two connecting plates 334. The linkage rod 333 is movably installed in the chute 3341. A connecting rod 332 is horizontally installed in the middle of each linkage rod 333.

By rotating the adjusting bolt 310, the plurality of connecting plates 334 arranged side by side and at intervals from top to bottom of the adjusting bolt 310 can be rotated, so that each linkage rod 333 slidably clamped in the chute 3341 on each connecting plate 334 moves along the arc-shaped chute 3341, so that the clamping blocks 331 connected by the connecting rods 332 on each linkage rod 333 move outwards, thereby clamping and fixing ceramic pipe sleeves with different inner diameters. At the same time, a locking block is provided on the side of the adjusting bolt 310 to lock and limit the rotating adjusting bolt 310 to prevent the adjusting bolt 310 on the clamping assembly 300 from rotating.

[0030] As a preferred embodiment, please refer to Figure 4 and Figure 5 , a plurality of connecting plates 334 are movably installed in the fixed cylinder 320, so that each connecting plate 334 rotates with the rotation of the adjusting bolt 310.

[0032] As a preferred embodiment, please refer to Figure 4 and Figure 5 , the outer side of the clamping block 331 is in an arc-shaped structure, so that the clamping block 331 can fit the inner diameter of different ceramic pipe sleeves, thereby clamping and fixing ceramic pipe sleeves with different diameters.

[0033] The working principle of the ceramic pipe sleeve curing device for a sampling probe of the present utility model is:

[0034] When curing the ceramic pipe sheath outside the sampling probe, the production personnel will place the ceramic pipe sheath to be cured outside the clamping assembly 300 arranged on the cover plate 200, so as to rotate the adjusting bolt 310, so that several connecting plates 334 on several clamping mechanisms 330 fixedly installed on the adjusting bolt 310 rotate, so that several linkage rods 333 move along the arc-shaped structure chute 3341 arranged on the connecting plate 334, so that the clamping blocks 331 fixedly connected to the connecting rods 332 horizontally installed in the middle of the linkage rods 333 move outwards, so as to clamp and fix the inner diameters of ceramic pipe sheaths with different diameters. After the clamped and fixed ceramic pipe sheath is placed into the curing cylinder 100, the connection port on the cover plate 200 is clamped and connected to the connection terminal 150 arranged on the curing cylinder 100, so that the PTC heating plate 130 electrically connected to the connection terminal 150 performs constant temperature heating, and the heat conducting plate 140 made of metal conducts the heat into the inner cavity of the curing cylinder 100. The foam heat preservation layer 120 and the protective shell 110 arranged outside the heating plate 130 reduce the heat loss of the heating plate 130, so that the internal cavity of the curing cylinder 100 maintains a constant temperature, so that the ceramic protective sheath is cured at a constant temperature in the curing cylinder 100, thereby improving the curing production efficiency and production quality of the sampling probe ceramic protective sheath by the curing device.

[0035] The beneficial effects of a ceramic pipe sheath curing device for a sampling probe of the present utility model are as follows:

[0036] First, by arranging a curing heat preservation cavity in the curing cylinder 100 of the curing device, the protective shell 110, the foam heat preservation layer 120, the self-limiting temperature heating tape heating plate 130 and the metal heat conducting plate 140 are arranged from outside to inside, so that the self-limiting temperature heating tape heating plate 130 heats the metal plate at a constant temperature, and the heat preservation layer 120 arranged outside keeps the temperature of the inner cavity of the curing cylinder 100 constant, so that the curing cylinder 100 cures the ceramic pipe sheath at a constant temperature, replacing the original room temperature placement curing, thereby improving the production efficiency and production quality of the ceramic pipe sheath;

[0037] Second, by arranging a clamping assembly 300 at the bottom of the cover plate 200 of the curing device, several clamping mechanisms 330 arranged on the clamping assembly 300 clamp and fix the inner diameters of ceramic pipe sheaths with different diameters under the rotation of the adjusting bolt 310, so that the ceramic pipe sheaths are evenly arranged at the position of the heat conducting plate 140 in the curing cylinder 100, so that the curing temperature is uniform, thereby improving the production efficiency and production quality of the ceramic pipe sheath.
