AI Technical Summary
The transmitter part of the probe in existing floor slab thickness detection equipment is prone to slippage during measurement, which can cause the measurement value to drift or fail. This is especially true when measuring high floors, where operator arm fatigue can cause the probe to not fit tightly against the floor slab.
A second mounting cylinder, a slider, a contact plate, and a second spring are provided at the end of the transmitter. The spring is compressed when the contact plate contacts the floor slab, increasing the friction to ensure that the transmitter fits tightly against the floor slab. A telescopic rod and connecting components are used to improve stability.
This improved the transmitter's operational stability, enhanced the accuracy of measurements, prevented the probe from wobbling at the bottom of the floor, and ensured the accuracy of measurements on high floors.

TECHNICAL FIELD
[0001] The application belongs to the technical field of building equipment, and particularly relates to a floor thickness detection equipment for building. BACKGROUND
[0002] The floor thickness detector is a portable nondestructive testing instrument for measuring the thickness of concrete or other non-ferromagnetic media. Its working principle is to place the transmitting probe and the receiving probe on the two opposite test surfaces of the floor respectively, and measure the thickness value through the received signal strength. Different models of detectors have split or all-in-one machine designs, and have data storage, analysis and report generation functions.
[0003] The applicant found that, during the measurement of the floor thickness by using the floor thickness detector, the person on the floor needs to use the telescopic rod to press the transmitting probe against the bottom surface of the floor. When measuring the height of the high floor exceeding 3.5 m, the measuring personnel need to use a long rod to hold the transmitter. After multiple point measurements, the operator is prone to cause the probe to not tightly adhere to the floor due to arm fatigue, and the transmitter cannot be tightly adhered to the floor, thereby causing the measurement value to drift or fail. Therefore, it is necessary to improve the structure of the probe transmitter part of the existing floor thickness detection equipment. SUMMARY
[0004] In order to overcome the shortcomings of the prior art, the purpose of the present application is to provide a floor thickness detection equipment for building, so as to solve the problem that the probe transmitter part of the existing floor thickness detection equipment is prone to slip when measuring the bottom of the floor.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0026] Embodiment one:
[0027] Please refer to Figure 1 - Figure 5 As shown in the figure, a building floor thickness detection device comprises:
[0028] The detector 1;
[0029] The receiver 6 is connected with the detector 1 through the wire 5, and the first mounting cylinder 61 is externally connected to the receiver 6, the rotating ball 62 is slidingly connected to the end of the first mounting cylinder 61, and the first spring 63 is arranged inside the first mounting cylinder 61;
[0030] The transmitter 7 is used for transmitting detection signals to the receiver 6, the second mounting cylinder 71 is connected to the transmitter 7, the sliding block 72 is slidingly connected to the end of the second mounting cylinder 71, the abutting disc 73 is connected to the sliding block 72, and the second spring 74 is arranged inside the second mounting cylinder 71;
[0031] The telescopic rod 8 is connected to the transmitter 7 and comprises the outer rod 81 and the inner rod 82, and the outer rod 81 and the inner rod 82 are connected through the connecting assembly 9.
[0032] As can be seen, by arranging the second mounting cylinder 71, the sliding block 72, the abutting disc 73 and the second spring 74 at the end of the transmitter 7, when the user sticks the transmitter 7 to the bottom of the floor for detection, the abutting disc 73 is in contact with the bottom of the floor, and at the same time, the abutting disc 73 compresses the second spring 74 through the sliding block 72, the elastic force of the second spring 74 forces the abutting disc 73 to be closely attached to the floor bottom, thereby increasing the friction between the abutting disc 73 and the floor bottom, avoiding the transmitter 7 from shaking on the floor bottom, increasing the working stability of the transmitter 7, and improving the accuracy of the measurement value. After the transmitter 7 is positioned, the measurer above the floor can stick the receiver 6 to the floor, at this time, the rotating ball 62 is in contact with the floor and rotates, when the receiver 6 moves to the position with the strongest signal, the receiver 6 can be pressed downward, so that the rotating ball 62 compresses the first spring 63 and retracts into the first mounting cylinder 61, so that the receiver 6 is attached to the floor, thereby accurately receiving the signal emitted by the transmitter 7 on the other side of the floor, and judging the thickness of the floor according to the signal attenuation intensity.
[0033] One end of the first spring 63 is in abutment with the inner wall of the first mounting cylinder 61, and the other end is in abutment with the rotating ball 62, one end of the second spring 74 is in abutment with the inner wall of the second mounting cylinder 71, and the other end is in abutment with the sliding block 72, thereby exerting a pre-pressure on the rotating ball 62 and the sliding block 72, avoiding the rotating ball 62 and the sliding block 72 from retracting into the mounting cylinder without external force.
[0034] A plurality of notches are arranged in annular array on the abutting disc 73, thereby increasing the friction between the abutting disc 73 and the floor, avoiding the transmitter 7 from sliding on the floor.
[0035] The connecting assembly 1, detector 2, adjustment key 3, power key 4, display screen 5, wire 5, receiver 6, first mounting cylinder 61, rotating ball 62, first spring 63, transmitter 7, second mounting cylinder 71, sliding block 72, abutting disc 73, second spring 74, telescopic rod 8, outer rod 81, inner rod 82, connecting assembly 9, clamping piece 91, friction plate 92, friction lines 93, and abutting cylinder 94 are provided.
[0036] Embodiment two:
[0037] Please refer to Figure 1 - Figure 5 A building floor thickness detection device is shown, comprising:
[0038] The detector 1;
[0039] The receiver 6 is connected to the detector 1 through the wire 5, and the first mounting cylinder 61 is connected to the outside of the receiver 6, the rotating ball 62 is slidingly connected to the end of the first mounting cylinder 61, and the first spring 63 is arranged in the first mounting cylinder 61.
[0040] The transmitter 7 is used to transmit detection signals to the receiver 6, and the second mounting cylinder 71 is connected to the transmitter 7, the sliding block 72 is slidingly connected to the end of the second mounting cylinder 71, the abutting disc 73 is connected to the sliding block 72, and the second spring 74 is arranged in the second mounting cylinder 71.
[0041] The telescopic rod 8 is connected to the transmitter 7, comprising the outer rod 81 and the inner rod 82, and the outer rod 81 and the inner rod 82 are connected through the connecting assembly 9.
[0042] As can be seen from the above, by arranging the second mounting cylinder 71, the sliding block 72, the abutting disc 73 and the second spring 74 at the end of the transmitter 7, when the user pastes the transmitter 7 on the bottom of the floor for detection, the abutting disc 73 is in contact with the bottom of the floor, at the same time, the abutting disc 73 compresses the second spring 74 through the sliding block 72, the elastic force of the second spring 74 forces the abutting disc 73 to closely adhere to the floor bottom, thereby increasing the friction between the abutting disc 73 and the floor bottom, avoiding the transmitter 7 from shaking on the floor bottom, increasing the working stability of the transmitter 7, and improving the accuracy of the measured value. After the transmitter 7 is positioned, the measurer above the floor can paste the receiver 6 on the floor, at this time, the rotating ball 62 is in contact with the floor and rotates, when the receiver 6 moves to the position with the strongest signal, the receiver 6 can be pressed downward, so that the rotating ball 62 compresses the first spring 63 and retracts into the first mounting cylinder 61, so that the receiver 6 is pasted on the floor, thereby accurately receiving the signal emitted by the transmitter 7 on the other side of the floor, and judging the thickness of the floor according to the signal attenuation intensity.
[0043] One end of the first spring 63 is in abutment with the inner wall of the first mounting cylinder 61, and the other end is in abutment with the rotating ball 62. One end of the second spring 74 is in abutment with the inner wall of the second mounting cylinder 71, and the other end is in abutment with the sliding block 72. In this way, the rotating ball 62 and the sliding block 72 are pre-pressed, avoiding the rotating ball 62 and the sliding block 72 from retracting into the mounting cylinder without external force.
[0044] A plurality of notches are arranged in annular array on the abutting disc 73, thereby increasing the friction between the abutting disc 73 and the floor, avoiding the transmitter 7 from sliding on the floor.
[0045] The connecting assembly 9 comprises a plurality of clamping pieces 91 fixedly arranged on the outer rod 81, a friction plate 92 connected to the inner wall of the clamping piece 91, and friction lines 93 arranged on the friction plate 92. The outer wall of the clamping piece 91 is gradually thickened from one end to the other end. A resisting cylinder 94 is threadedly connected to the outer rod 81. When the measurer needs to measure the floor at a high place, the length of the telescopic rod 8 can be increased by extending the outer rod 81 and the inner rod 82, and then rotating the resisting cylinder 94 to make it move on the outer rod 81 and abut against the outside of the clamping piece 91. Due to the inclined and gradually thickened arrangement of the outer wall of the clamping piece 91, the clamping piece 91 deforms inward to press the friction plate 92 under the action of the resisting cylinder 94, so that the friction plate 92 is in close contact with the inner rod 82. The friction between the friction plate 92 and the inner rod 82 can limit the sliding of the inner rod 82. In order to further increase the friction of the friction plate 92, the friction plate 92 is made of rubber.
[0046] In order to make the friction force borne by the inner rod 82 uniform, a plurality of clamping pieces 91 are arranged in annular array at the end of the outer rod 81.
[0047] The detector 1 is connected with an adjusting key 2, a power key 3 and a display screen 4.
