DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] Example 1

[0025] See also Figures 1 to 4 , which is the first embodiment of the present invention, and this embodiment provides a technical solution: a building track measuring instrument, comprising

[0026] A measuring head 1, a measuring host 2 connected to the measuring head 1 via a connecting line, and a top seat 11 welded and fixed to the top surface of the measuring head 1;

[0027] A horizontal base plate 4 is slidably mounted above the building track 3, the bottom end of the measuring head 1 penetrates to the bottom of the horizontal base plate 4 and fits with the building track 3, and the top seat 11 fits on the top surface of the horizontal base plate 4, and a through hole for the measuring head 1 to penetrate is opened at the center of the horizontal base plate 4;

[0028] The crimping structure 5 disposed between the horizontal base plate 4 and the top seat 11 includes a movable cartridge seat 51 movably mounted on the top surface of the horizontal base plate 4, a limiting pressure block 52 welded and fixed to the side of the movable cartridge seat 51, and a side card slot 53 provided on the top surface of the top seat 11. The limiting pressure block 52 is inserted into the side card slot 53 to achieve the clamping and limiting of the top seat 11, thereby ensuring the installation stability of the measuring head 1. The crimping structure 5 also includes a cylindrical inner groove 58 provided in the movable cartridge seat 51, a circular inner groove 58 installed in the cylindrical inner groove 58, and a cylindrical inner groove 58 provided in the movable cartridge seat 51. The cylindrical inner base block 56 and the spring 55 are fixed to the cylindrical connecting rod 57 on the top surface of the horizontal base plate 4. The top end of the cylindrical connecting rod 57 passes through the cylindrical inner groove 58 and is fixed to the cylindrical inner base block 56. Under the pushing action of the spring 55, the limit pressing block 52 can be stably stuck in the side groove 53 during daily use to achieve stable limit of the top seat 11. During actual installation, it is only necessary to lift and rotate the movable cylinder seat 51 so that the limit pressing block 52 can be rotated to the side of the horizontal base plate 4 without causing any damage to the measuring head. 1 is inserted into the through hole at the center of the horizontal base plate 4, and the top seat 11 is fitted with the top surface of the horizontal base plate 4. Then the movable cylinder seat 51 is lifted, so that the spring 55 is gradually compressed, so that the height of the limit pressure block 52 is higher than the top surface height of the top seat 11. Then the movable cylinder seat 51 is rotated so that the limit pressure block 52 can be rotated to the top of the top seat 11, and the limit pressure block 52 is aligned with the side card slot 53. At this time, the movable cylinder seat 51 is released, so that the spring 55 will move the movable cylinder seat 51. By pushing the movable cylinder seat 51 back, the limit pressure block 52 can be snapped into the side slot 53, so as to realize the clamping and limiting of the top seat 11. At this time, the bottom end of the measuring head 1 will always keep in contact with the top surface of the building track 3, so as to improve the subsequent measurement stability of the building track 3. Subsequently, it is only necessary to slide the horizontal base plate 4 on the top of the building track 3 to enable the measuring head 1 to measure the hardness of the building track 3. In the whole process, the operator does not need to operate the measuring head 1, but only needs to continuously push the horizontal base plate 4, so the measurement is very convenient.

[0029] A circular rod hole is provided on the bottom surface of the movable cylinder seat 51 , and the circular rod hole corresponds to the cylindrical connecting rod 57 , so as to facilitate the smooth penetration and subsequent rotation of the cylindrical connecting rod 57 .

[0030] The bottom end of the spring 55 abuts against the inner wall of the bottom end of the cylindrical inner groove 58 , and the top end of the spring 55 abuts against the bottom surface of the cylindrical inner base block 56 .

[0031] Among them, two horizontal slide grooves 63 are symmetrically provided inside the horizontal base plate 4, and a horizontal slide block 64 and a reset spring 65 are installed in the horizontal slide groove 63. A connecting bottom block 66 is fixed to the bottom surface of the horizontal slide block 64. A connecting slideway 67 corresponding to the connecting bottom block 66 is provided on the bottom surface of the horizontal base plate 4. The bottom end of the connecting bottom block 66 passes through the connecting slideway 67 to the bottom of the horizontal base plate 4 and is fixed with a side guide plate 61. The bottom end of the side guide plate 61 extends to one side of the building track 3 and is fixed with a guide slide block 62. The guide slide block 62 slides in the slide groove on the side of the building track 3, so that the horizontal base plate 4 can slide stably above the building track 3. When the horizontal base plate 4 needs to be removed laterally, it is only necessary to pull the two side guide plates 61 sideways to make the connecting bottom block 66 slide sideways with the horizontal slide block 64, and make the reset spring 65 gradually stretched until the guide slide block 62 moves out of the slide groove on the side of the building track 3, so that the horizontal base plate 4 can be directly separated from the building track 3, which is convenient for the subsequent disassembly and assembly of the horizontal base plate 4.

[0032] Among them, a ball is installed on the top surface of the guide slider 62 to roll with the inner wall of the slide groove, which can reduce the friction resistance of the guide slider 62 when sliding.

[0033] One end of the return spring 65 is fixed to the inner wall of the transverse sliding groove 63 , and the other end of the return spring 65 is fixed to the transverse sliding block 64 .

[0034] Example 2

[0035] See also Figures 1 to 5 , which is the second embodiment of the present invention, is based on the previous embodiment, and the difference is that auxiliary positioning of the movable cylinder seat 51 after rotation can be achieved by setting up structures such as the L-shaped rubber seat 54.

[0036] Specifically, the crimping structure 5 also includes an L-shaped rubber seat 54 which is glued and fixed to the top of the horizontal base plate 4 and located on one side of the movable cylinder seat 51. The L-shaped rubber seat 54 is made of rubber material and will be elastically deformed when squeezed. A positioning groove 541 is opened on the inner side of the L-shaped rubber seat 54. A positioning protrusion 511 corresponding to the positioning groove 541 is welded and fixed on the surface of the movable cylinder seat 51, and the positioning protrusion 511 is embedded in the positioning groove 541, so that when the operator lifts the movable cylinder seat 51 and rotates the limit pressure block 52 to the top of the top seat 11, the positioning protrusion 511 will be squeezed into the positioning groove 541. 41, thereby playing an auxiliary positioning role for the movable cylinder seat 51 and the limiting pressure block 52, prompting the operator that the limiting pressure block 52 has been aligned with the side slot 53. At this time, the operator releases the movable cylinder seat 51, which can make the limiting pressure block 52 stably snap into the side slot 53. If the movable cylinder seat 51 is to be lifted up and the limiting pressure block 52 is rotated and removed later, it is only necessary to rotate the movable cylinder seat 51 with force after lifting the movable cylinder seat 51, so that the L-shaped rubber seat 54 can be elastically deformed, and the positioning protrusion 511 can be squeezed out of the positioning slot 541, so that the movable cylinder seat 51 can be smoothly rotated.

[0037] Although embodiments of the present invention have been shown and described (see the above detailed description for details), it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
