Description

Technical Field

[0001] The utility model belongs to the technical field of building construction inspection, and specifically relates to a rapid positioning device for a floor thickness gauge. Background Technique

[0002] A floor slab refers to a building structure generated between floors during the construction of a house. In construction projects, it is necessary to use a floor thickness gauge to detect the thickness of the floor slab;

[0003] According to the application number CN202322465706.2 and the name of a rapid positioning device for inspection points of a floor thickness gauge, it includes a receiving device for receiving signals and a transmitting device for transmitting signals. The characteristics are as follows: A detector is fixedly installed on the upper surface of the receiving device; a telescopic rod for supporting the transmitting device is fixedly connected to the lower surface of the transmitting device; a display screen for displaying data is arranged on the upper surface of the detector; the receiving device includes a first protective shell, and a receiving probe for receiving positioning signals is fixedly installed inside the first protective shell. A first tape measure for measuring the distance between the receiving device and the wall is fixedly installed on the side of the first protective shell; the transmitting device includes a second protective shell, and a transmitting probe for transmitting positioning signals is fixedly installed inside the second protective shell. A housing is fixedly connected to the side of the second protective shell. A second tape measure for measuring the distance between the transmitting device and the wall is fixedly connected inside the housing. One end of the second tape measure extends to the outside of the housing and is movably connected to the outer wall of the housing. A limiting plate is fixedly connected to one end of the second tape measure. An ultra-strong tape for pasting the limiting plate on the wall is fixedly connected to the surface of the limiting plate. A camera for photographing the measured value of the second tape measure is fixedly connected to the top wall of the inner cavity of the housing;

[0004] This device performs rapid positioning through a tape measure. When fixing the tape measure, the strong tape is adhered to the wall. Since concrete walls are often not completely smooth, and during the construction process, a large amount of concrete particles, dust, and other impurities may adhere to the surface. When the strong tape is attached to such a wall, these impurities will not only affect the effective contact area between the tape and the wall, but may also directly embed into the adhesive layer of the tape, resulting in a significant reduction in the adhesive force of the tape. Over time, the stickiness of the tape will gradually weaken, and it may even become loose or fall off, thus directly affecting the fixation of the tape measure. Therefore, improvements are needed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 7 shown, the present invention provides a rapid positioning device for a floor thickness gauge, which includes a main unit 1 and a transmitting probe 2. Mounting plates 3 are fixedly installed on the right sides of both the main unit 1 and the transmitting probe 2. Measuring tape boxes 4 are fixedly installed at the front ends of the mounting plates 3. A measuring tape 5 is arranged inside the measuring tape box 4. An expansion rod 19 is arranged at the bottom end of the transmitting probe 2;

[0026] A locking mechanism is arranged on the right side of the measuring tape box 4. The locking mechanism includes a positioning plate 6. The positioning plate 6 is fixedly connected to the right side of the measuring tape box 4, and the top end of the measuring tape box 4 is in contact with the bottom end of the measuring tape 5. A fixed shell 7 located at the top of the measuring tape 5 is fixedly installed on the right side of the measuring tape box 4. A slider 8 is slidably connected inside the fixed shell 7. A sliding rod 9 is fixedly installed at the bottom end of the slider 8. A sliding rod 9 is fixedly installed inside the top end of the slider 8. A hinge block 10 located inside the slider 8 is slidably connected to the surface of the sliding rod 9. A push rod 11 is hinged inside the hinge block 10. The right end of the push rod 11 is fixedly installed with a rotating rod 12. The rotating rod 12 penetrates through the fixed shell 7 to the right and is fixedly installed with a connection block 13 located outside the fixed shell 7. Fixing grooves 15 are opened on the right sides of both the fixed shell 7 and the connection block 13. An insertion block 16 is inserted into the fixing groove 15.

[0027] Adopting the above solution: The operator uses the expansion rod 19 to make the top end of the transmitting probe 2 contact the bottom end of the slab floor, and then pulls the measuring tape 5 on the right side of the transmitting probe 2 to make the right end of the measuring tape 5 contact the wall. After contacting the wall, the connection block 13 can be rotated to make the rotating rod 12 rotate. Then, the rotating rod 12 will drive the push rod 11 to rotate. Since the push rod 11 is hinged to the hinge block 10, when the push rod 11 rotates, it will push the hinge block 10 to move on the surface of the sliding rod 9. Then, the push rod 11 will push the sliding rod 9 and the slider 8 to descend. Then, the slider 8 will drive the contact block 14 to descend. Then, the bottom end of the contact block 14 will contact the top end of the measuring tape 5, and the contact block 14 will squeeze the measuring tape 5. While squeezing, the fixing groove 15 on the surface of the connection block 13 will be aligned with the fixing groove 15 on the right side of the fixed shell 7. Then, the insertion block 16 can be inserted into the fixing groove 15 to fix the connection block 13 and the rotating rod 12. Finally, through the cooperation between the contact block 14 and the positioning plate 6, the measuring tape 5 can be locked without using strong tape, thereby increasing the practicability of the device;

[0028] After the locking is completed, the main unit 1 can be placed on the top of the slab building, and then the tape measure 5 is also pulled so that the lengths of the tape measure 5 on the right side of the transmitting probe 2 and the tape measure 5 on the right side of the main unit 1 are the same. After the lengths of the tape measure 5 on the right side of the main unit 1 and the tape measure 5 on the right side of the transmitting probe 2 are the same, the tape measure 5 on the right side of the main unit 1 is fixed in the same way, so as to achieve rapid positioning. After the positioning is completed, the transmitting probe 2 is driven to emit a measurement signal, and then the main unit 1 will receive the signal, so as to measure the floor slab.

[0029] As Figure 2 and Figure 6 shown, a limiting groove 17 is opened on the left side inside the fixing shell 7. A limiting block 18 is slidably connected inside the limiting groove 17. The right sides of the limiting blocks 18 are fixedly connected to the left side of the slider 8. The limiting block 18 is designed in a T shape, and the limiting block 18 fits against the inner wall of the limiting groove 17. A threaded rod 20 is provided at the bottom end of the telescopic rod 19, and a base 21 is threadedly sleeved on the surface of the threaded rod 20.

[0030] With the above scheme: Through the design of the limiting groove 17 and the limiting block 18, when the slider 8 moves, the slider 8 will drive the limiting block 18 to move inside the limiting groove 17. Since the limiting block 18 is designed in a T shape and fits against the inner wall of the limiting groove 17, the moving direction of the slider 8 will be limited, and the slider 8 can move smoothly. Through the design of the threaded rod 20 and the base 21, the base 21 can be sleeved on the surface of the threaded rod 20, and then the base 21 is rotated. Since the threaded rod 20 and the base 21 are threadedly sleeved, the base 21 will be fixed at the bottom end of the telescopic rod 19. When the telescopic rod 19 supports the transmitting probe 2, the base 21 will contact the ground, so as to increase the contact area with the ground, and thus increase the stability of the support of the telescopic rod 19.

[0031] As Figure 5 shown, a circular groove 22 is opened inside the right end of the fixing shell 7. A limiting ring 23 located on the surface of the rotating rod 12 is rotatably connected inside the circular groove 22. The limiting ring 23 is fixedly connected to the rotating rod 12. The surface of the sliding rod 9 is designed to be smooth, and the surface of the hinge block 10 fits fully against the inner wall of the sliding rod 9.

[0032] With the above scheme: Through the design of the circular groove 22 and the limiting ring 23, when the rotating rod 12 rotates, the limiting ring 23 will rotate inside the circular groove 22, so as to limit the rotating rod 12 and prevent the position from shifting when the rotating rod 12 rotates, affecting the normal movement of the slider 8. Through the design of the sliding rod 9 and the hinge block 10, since the surface of the sliding rod 9 is designed to be smooth, when the push rod 11 rotates, the hinge block 10 can move more smoothly, and the surface of the hinge block 10 fits against the inner wall of the sliding rod 9, so as to limit the hinge block 10.

[0033] As Figure 4 and Figure 7 shown, the sides of the positioning plate 6 opposite to the contact block 14 are both rough-designed. There is a gap between the fixed shell 7 and the tape measure 5. The number of fixing grooves 15 is two, and they are longitudinally symmetrically designed about the center of the connecting block 13. The insertion block 16 is U-shaped, and the insertion block 16 can be inserted into the interiors of the two fixing grooves 15 simultaneously.

[0034] With the above solution: Through the design of the positioning plate 6, the fixed shell 7 and the contact block 14, since there is a gap between the fixed shell 7 and the tape measure 5, when the tape measure 5 moves, the fixed shell 7 will not interfere with the movement of the tape measure 5. Moreover, the sides of the positioning plate 6 opposite to the contact block 14 are both rough-designed. When the slider 8 contacts the surface of the tape measure 5, the friction with the tape measure 5 can be increased, thereby increasing the fixing effect on the tape measure 5. Through the design of the fixing grooves 15 and the insertion block 16, since the fixing grooves 15 are symmetrically designed and the insertion block 16 is U-shaped, they are thus adapted to the fixing grooves 15, facilitating the fixing of the connecting block 13.

[0035] The working principle and usage process of the present utility model are as follows:

[0036] First, the operator can fix the base 21 on the surface of the threaded rod 20. Then, use the telescopic rod 19 to make the top of the transmitting probe 2 contact the bottom end of the floor slab. Then, the telescopic rod 19 can support the transmitting probe 2. Next, the right tape measure 5 can be pulled to move, and then the right end of the tape measure 5 is made to contact the wall. After the contact, the connecting block 13 and the rotating rod 12 can be rotated. Then, the rotating rod 12 will drive the push rod 11 to rotate. The push rod 11 will push the hinge block 10 to move on the surface of the sliding rod 9, and the push rod 11 will push the slider 8 and the contact block 14 to descend. Then, the bottom end of the contact block 14 will contact the top end of the tape measure 5. Next, the contact block 14 will squeeze the tape case 4. While squeezing, the two fixing grooves 15 will coincide, and then the insertion block 16 can be inserted into the interiors of the fixing grooves 15 to fix the connecting block 13 and the rotating rod 12. Then, the slider 8 and the positioning plate 6 cooperate with each other to fix the tape measure 5. After the fixing is completed, the main unit 1 can be placed on the top of the slab building, and then the tape measure 5 on the right side of the main unit 1 is extended to the same length to contact the wall, so as to quickly position, and the same method is used for fixing. Then, the floor slab can be measured, and finally the operation process is completed.
