The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, a kind of resistivity electronic compartment, it comprises aligning assembly 1, short protection tube 2, short central joint 3, the adaptive joint 4 of transferring, long protection tube 5, long center sub 6, short central connector cover 7, long center sub lid 8.Aligning assembly 1 is connected with the internal thread of short protection tube 2 by the end external screw thread, the other end of short protection tube 2 is connected with the external screw thread of short central joint 3 by internal thread, the other end of short central joint 3 is connected with the adaptive joint 4 of switching by circlip for shaft, the other end of adaptive joint 4 of transferring is connected with the internal thread of long protection tube 5 by external screw thread, the other end of long protection tube 5 is connected with the external screw thread of long center sub 6 by internal thread, the other end of long center sub 6 is connected with the internal thread of short protection tube 2 by external screw thread, the other end of short protection tube 2 is connected with aligning assembly 1 by internal thread.Short central connector cover 7 is fixed on by screw 17 on the outer wall of short central joint 3, and long center sub lid 8 is fixed on the outer wall of long center sub 6 by screw 17, has jointly formed the resistivity electronic compartment.
As shown in Figure 2, a kind of structure of aligning assembly, it comprises aligning rubber 13, rubber standoff 14, screw 15, support 16.As shown in Figure 3, support 16 middle parts are along circumferentially making hexagon, in order to reduce the difficulty of processing of aligning rubber 13, avoid aligning rubber 13 to be directly installed on pressurized on support 16 and produce moderate finite deformation, affect the effectiveness in vibration suppression of aligning assembly, aligning rubber 13 is made to rectangle, in the slot of the rubber standoff of packing into 14, after packing resistivity body compressive deformation into, hurt by rubber standoff 14 aligning rubber 13, the edge designs of rubber standoff 14 has fillet, in order to ensure at-20 ° of C ~ 150 ° C, strong vibration, under the shock environment condition, the effectiveness in vibration suppression of aligning assembly 1, according to resistivity body 12, aligning rubber 13, rubber standoff 14, the material thermal expansion coefficient of support 16, the rigidity of aligning rubber 13 and damping, rubber standoff 14 end faces are lower than more than aligning rubber 13 end face 5mm, preferred 10mm.3 rubber standoff 14 are distributed on the radial position of support 16, rubber standoff 14 bottom design become the v-shaped openings of 120 degree angles, with two faces of six prisms of support 16, coordinate, cylindrical hole has been offered in its axial centre position, V font bottom, and screw 15 is fixed on support 16 through the step cutting pattern hole of aligning rubber 13, the cylindrical hole of rubber standoff 14.As shown in Figure 4, aligning assembly 1 contacts with resistivity body 12 inner chambers, has realized the resiliency supported between aligning assembly 1 and resistivity body 12 inner chambers, reaches the purpose of resistivity electronic compartment vibration damping.Determine material and the hardness of aligning rubber 13 according to ambient conditions.
As shown in Figure 5, short central connector cover 7 is fixed on short central joint 3 by 3 screws 17, be shaped with 4 cylindrical bosses on short central connector cover 7 arc surfaces, lug boss position is positioned at the radially connector position be arranged on short central joint 3, as shown in Figure 6, each outer wall of boss is offered the annular radial sealed groove, avoided O RunddichtringO 9 to break away from from sealed groove when assembling, if or employing end face seal form, dimensional tolerance accumulative total causes the O RunddichtringO not contact with resistivity body 12, thereby affects the risk of sealing effectiveness.Because ambient pressure is larger, only adopt one sealing ring to be difficult to meet instructions for use, but resistivity body 12 radial direction limited spaces, radial dimension is only enough installed the space of single track O RunddichtringO, therefore in order to realize the effective sealing of 4 cylindrical boss positions, 2 rectangle grooves have been placed on short central connector cover 7 arc surfaces, as shown in Figure 7, 4 cylindrical bosses drop in 2 rectangle frames fully, by O RunddichtringO 10, O RunddichtringO 11 is respectively charged in rectangle groove, realize the second between short central connector cover 7 and resistivity body 12, three seal structures.As shown in Figure 5, screw 18 radially is connected resistivity electronic compartment and resistivity body 12, and 3 seal structures on short central connector cover 7 are contacted with the inner chamber of resistivity body 12, has realized that the elastic packing of resistivity tester connects.Determine material and the hardness of sealing ring 9, sealing ring 10, sealing ring 11 according to ambient conditions.
The installation form of long center sub lid 8 and resistivity body 12, basically identical with the installation form of resistivity body 12 with short central connector cover 7, no longer elaborate here.
