In this preferred scheme, can reduce whole detection device's the processing degree of difficulty through this kind of preferred mode, after hollow tube 31a tip heating, can be relatively easy reach can make the state that the part of rubber seat 32 melts, this kind melts the purpose and lies in making the part of rubber seat 32 can soften softly and can adapt to the insertion of hollow tube 31a and realize remolding of shape to reach the better connected state with hollow tube 31 a.
In order to improve the connection strength, a part of the hollow pipe body 31a inserted into the rubber seat 32 is provided with a plurality of through holes 31a-1 penetrating through the side wall; the through hole 31a-1 is arranged in the material remolding process of the rubber seat 32, so that part of the material can enter the area of the through hole 31a-1, better connection effect with the rubber seat 32 can be ensured after cooling and solidification, and the stability in the subsequent use process is improved; it should be emphasized that, in the subsequent use, since the state of the telescopic rod 31 basically includes both the natural state and the compressed state, the risk of removal by pulling relative to the rubber seat 32 is low, and the above situation can fully satisfy the actual use requirement. When the processing difficulty is reduced, the arrangement of the through hole 31a-1 can be replaced by increasing the friction coefficient of the end surface of the hollow tube 31a, so that the connection strength can be increased, but the difficulty of inserting the rubber seat 32 can be increased, and the method can be selected according to the actual production environment, the yield requirement and the like.

installing a combined structure which is assembled and at least comprises a sounding component and a sound insulation cover body in the first detection area, and applying pressure to the rubber seat to enable the telescopic rod bodies and the building element to be detected to be in adaptive retraction, so that the working area of the sound insulation cover body is closed through the building element to be detected in the first detection area;
installing a combined structure which is assembled and at least comprises a decibel meter and a sound insulation cover body in the second detection area, and applying pressure to the rubber seat to enable the shape of each telescopic rod body and the shape of the building element to be detected to be retracted in a self-adapting manner, so that the working area of the sound insulation cover body is closed through the building element to be detected in the second detection area;
controlling the sounding component to sound, and synchronously starting the decibel meter to collect sound signals;
and comprehensively referring to the control parameters of the sounding component and the acquisition result of the decibel meter to evaluate the sound insulation effect of the building component.
8. The use method of the assembly type building component sound insulation detection device according to claim 7, wherein after the sound production assembly and the decibel meter are removed, the assembly type building component sound insulation detection device is stored in a manner that the telescopic rod bodies are gathered towards the center, and in the storage process, the rubber seat deforms.
