Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 3 As shown, a quick-release composite sensor connection housing includes a connector 1 and a quick-release component 2 threadedly installed on the upper end of the connector 1, the connector 1 is installed on the inner side of a body 4 to be installed, the connector 1 includes a housing shell 11 and a connecting portion 12 installed at the lower end of the housing shell 11, a thread is provided on the outer side of the connecting portion 12, a mounting groove 41 is provided in the middle of the body 4 to be installed, the mounting groove 41 matches the lower end of the connector 1, and the connecting portion 12 is threadedly connected to the bottom of the mounting groove 41 by rotating the housing shell 11 to achieve a preliminary connection effect.

[0035] like Figure 4 As shown, a center frame assembly 3 is provided inside the connecting piece 1 and the quick release piece 2, and the connecting piece 1 and the quick release piece 2 squeeze and fix the center frame assembly 3 in the middle, and the probe end of the center frame assembly 3 is inserted into the inside of the connecting part 12, and then connected to the connecting piece 1 through the quick release piece 2, so that the center frame assembly 3 is squeezed and fixed between the connecting piece 1 and the quick release piece 2, and the preliminary installation of the center frame assembly 3 is completed.

[0036] like Figure 5-Figure 6 As shown, the quick release part 2 includes a quick release cover 21 and a locking drive end 22 fixedly arranged on one side of the quick release cover 21, a threaded ring 223 is arranged between the quick release cover 21 and the locking drive end 22, an internal thread groove 111 is opened on the inner side of the accommodating shell 11, and the threaded ring 223 matches the internal thread groove 111. By rotating the quick release cover 21, the initial connection between the connector 1 and the quick release part 2 can be achieved through the matching relationship between the threaded ring 223 and the internal thread groove 111.

[0037] like Figure 3-Figure 6 as well as Fig.10 As shown, a longitudinal locking piece 13 is installed on the inner side of the accommodating shell 11, and the longitudinal locking piece 13 penetrates the accommodating shell 11 longitudinally. A transverse locking piece 14 is installed on the inner side of the accommodating shell 11 located on the upper end side of the longitudinal locking piece 13, and the transverse locking piece 14 penetrates the accommodating shell 11 transversely. A locking hole 23 is provided on the locking driving end 22, and the locking driving end 22 is an arc-shaped sheet. A bottom oblique groove 221 is provided at one end of the locking driving end 22, and a side oblique groove 222 is provided at one end of the locking driving end 22. The bottom oblique groove 221 and the side oblique groove 222 are at the same end, and a fixing hole 42 is provided on the body 4 to be installed located on the inner side of the installation groove 41.

[0038] When the connecting part 12 is threadedly connected to the mounting groove 41 to the limit, the fixing hole 42 corresponds to the longitudinal locking piece 13. After the initial connection between the connecting part 1 and the quick release part 2, the quick release cover 21 continues to be rotated. At this time, the bottom inclined groove 221 of the locking driving end 22 pushes the longitudinal locking piece 13 to move downward and insert it into the inner side of the fixing hole 42. At the same time, the side inclined groove 222 pushes the transverse locking piece 14 to move in the opposite direction. When the longitudinal locking piece 13 is inserted to the bottom, the transverse locking piece 14 corresponds to the locking hole 23. The transverse locking piece 14 is inserted into the locking hole 23 under the reset force, thereby perfectly connecting the connecting part 1 and the quick release part 2, which not only ensures that the threaded connection relationship between the connecting part 1 and the quick release part 2 will not be loose, but also ensures that the connection relationship between the connecting part 1 and the body 4 to be installed will not be loose, so that the stability is higher during long-term use and the data will not deviate.

[0039] like Figure 7 As shown, the longitudinal locking member 13 includes a trigger end 131 and a return spring 132 fixedly installed on the lower side of the trigger end 131, and the end of the return spring 132 away from the trigger end 131 is fixedly provided with a support ring 134, and the end of the support ring 134 away from the return spring 132 is fixedly connected to the accommodating shell 11, and a locking rod 133 is fixedly provided on the side of the trigger end 131 located in the middle of the return spring 132, and the locking rod 133 movably penetrates the support ring 134, and the fixing hole 42 matches the locking rod 133. The locking drive end 22 rotates to drive the bottom inclined groove 221 to rotate. At this time, the tip of the bottom inclined groove 221 squeezes the trigger end 131, and the trigger end 131 moves downward with the rotation, thereby driving the locking rod 133 to move downward and insert into the fixing hole 42. On the contrary, when the locking drive end 22 is reversed, the trigger end 131 is reset under the action of the return spring 132, which is convenient for secondary use.

[0040] like Figure 6 and Figure 8 As shown, the transverse locking member 14 includes an unlocking piece 141, a through hole 112 is provided on the accommodating shell 11, the maximum diameter of the unlocking piece 141 is larger than the diameter of the through hole 112, a latch 142 is fixedly installed on the side of the unlocking piece 141 facing the through hole 112, the locking hole 23 matches the latch 142, and a return spring 2 143 is installed on the unlocking piece 141 located on the outer side of the latch 142, and a support ring 2 144 is fixedly provided on the end of the return spring 2 143 away from the unlocking piece 141, and the end of the support ring 2 144 away from the return spring 2 143 is fixedly connected to the accommodating shell 11, and the locking driving end 22 rotates to drive the side oblique groove 222 to push, at this time, the tip of the side oblique groove 222 squeezes the latch 142 to move outward, and when the locking driving end 22 rotates to make the latch 142 match the locking hole 23, the return spring 2 143 is reset to drive the latch 142 to insert into the locking hole 23, so as to achieve a locking effect.

[0041] like Figure 3 and Fig. 9 As shown, the center frame assembly 3 includes a mounting frame 31 and a transfer column 32 fixedly installed at the lower end of the mounting frame 31, the mounting frame 31 includes an upper support plate 311 and a U-shaped frame 312 fixedly installed at the lower end of the upper support plate 311, a lower support plate 313 is fixedly installed at the lower end of the U-shaped frame 312, a wire tube 15 is fixedly installed on one side of the accommodating shell 11, the transfer column 32 is connected to the mounting frame 31, a plurality of spring tubes 33 are fixedly installed at the lower end of the transfer column 32, the spring tubes 33 are connected to the transfer column 32, a probe protective shell 34 is fixedly provided at the lower end of the spring tubes 33, and the probe protective shell 34 is connected to the spring tubes 33.

[0042] The sensor processor is installed between the U-shaped frames 312, and the probe with the wire is inserted into the probe protective shell 34, where multiple different types of sensor probes can be inserted, and then the wire is connected to the sensor processor through the spring tube 33 and the transfer column 32. The external wire of the sensor processor passes through the external connection through the wire tube 15. The center frame assembly 3 is an integrated assembly, which is not only convenient for installation with the connector 1 and the quick-release part 2, but also can be removed as a whole for maintenance or replacement during disassembly, without disassembling the entire composite sensor. The disassembly and assembly operation is simple and convenient.

[0043] like Figure 4 and Fig. 9 As shown, an extrusion block 25 is fixedly provided on one side of the inside of the quick release part 2, and the extrusion block 25 is arranged in a cone shape. An extrusion groove 314 is provided on the upper end of the upper support plate 311, and the extrusion groove 314 matches the extrusion block 25. When the quick release part 2 is rotated for installation, the extrusion block 25 will be driven to insert into the extrusion groove 314, and the entire center frame assembly 3 will be squeezed at the same time, which not only makes the entire center frame assembly 3 compactly installed, but also ensures that the probe is always attached to the body to be installed 4, thereby improving the sensing effect of the sensor.

[0044] like Figure 4 and Fig.10 As shown, an anti-skid plate 331 is arranged between the spring tube 33 and the probe protective shell 34. The anti-skid plate 331 matches the inner bottom of the containing shell 11, and has a certain anti-sway effect after the center frame assembly 3 is inserted into the inner side of the containing shell 11. Moreover, when the quick release part 2 and the connecting part 1 rotate, the friction between the anti-skid plate 331 and the connecting part 1 is large, so that when the quick release part 2 rotates, the center frame assembly 3 rotates with a small amplitude, thereby avoiding wire entanglement and improving the use effect.
