Description

Technical Field

[0001] The utility model particularly relates to an aperture detection device for house construction supervision. Background Art

[0002] Housing construction refers to the engineering entity formed by the construction of various types of housing buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Housing construction" refers to a project with a roof, beams, columns, walls, foundations, and internal space that can meet people's needs for production, residence, study, and public activities. In housing construction projects, general supervisors use vernier calipers to detect the aperture size. Therefore, there is a special need for an aperture detection device for housing construction supervision.

[0003] However, in the existing aperture detection device for house construction supervision, during use, the measuring claws of the vernier caliper need to frequently contact the aperture side wall of the measured object, but the measuring claws and the vernier caliper are usually an integrated structure, so that the measuring claws cannot be replaced after being worn, which affects the overall use of the vernier caliper and causes inconvenience in use.

[0004] Therefore, it is necessary to provide an aperture detection device for house construction supervision to improve the above-mentioned problems. Utility Model Content

[0005] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide an aperture detection device for house construction supervision.

[0006] A bore diameter detection device for house construction supervision comprises a main scale, a vernier scale movably mounted on the main scale, and inner measuring claws fixedly connected to the main scale and the vernier scale, wherein the inner measuring claws are respectively provided with anti-wear sheets; the anti-wear sheets respectively cover the opposite surfaces of the two inner measuring claws, the inner side of the anti-wear sheets is provided with elastically deformable buckles, and the inner measuring claws are provided with slots for cooperating with the buckles.

[0007] In one embodiment, the anti-wear plate includes a first connecting wall and a second connecting wall that are vertically spliced ​​to each other, the first connecting wall covers the measuring surface of the inner measuring claw, the buckle is formed on the second connecting wall, and a clamping area is formed between the first connecting wall and the buckle.

[0008] In one embodiment, a positioning pin is provided on one side of the anti-wear plate, and a positioning hole is provided on one side of the inner measuring claw corresponding to the positioning pin.

[0009] In one embodiment, a screw hole connected to the card slot is provided on one side of the inner measuring claw, and the inner thread of the screw hole is connected with a machine screw that can be tightly pressed against one side of the buckle.

[0010] In one embodiment, one end of the buckle protrudes outward from one side of the inner measuring claw.

[0011] In one embodiment, external measuring claws are fixedly connected to the main scale and the vernier scale respectively.

[0012] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0013] The utility model installs the anti-wear sheet on the measuring claw so that the anti-wear sheet contacts the object to be measured to measure the aperture of the object to be measured; and when the anti-wear sheet is worn out due to long-term use, resulting in deviations in the measured value, the user can remove and replace the anti-wear sheet by pressing the buckle of the anti-wear sheet, thereby facilitating the protection of the measuring claw and avoiding the problem that the measuring claw cannot be replaced after being worn and needs to be scrapped as a whole.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0020] like Figures 1 to 5 The embodiment of the utility model shown preferably provides an aperture detection device for house construction supervision, including a main scale 1, a vernier scale 2 movably mounted on the main scale 1, and inner measuring claws 3 fixedly connected to the main scale 1 and the vernier scale 2, and anti-wear sheets 4 are respectively provided on the inner measuring claws 3; the anti-wear sheets 4 respectively cover the opposite surfaces of the two inner measuring claws 3, and the inner side of the anti-wear sheets 4 is provided with elastically deformable buckles 5, and the inner measuring claws 3 are provided with slots 6 for matching with the buckles 5.

[0021] Specifically, the anti-wear sheet is installed on the measuring claw so that the anti-wear sheet can contact the object to be measured to achieve the measurement of the aperture of the object to be measured; and when the anti-wear sheet is worn out due to long-term use, resulting in deviations in the measured value, the user can press the buckle of the anti-wear sheet to disassemble and replace the anti-wear sheet, thereby facilitating the protection of the measuring claw and avoiding the problem that the measuring claw cannot be replaced after being worn and needs to be scrapped as a whole.

[0022] Furthermore, the anti-wear sheet 4 includes a first connecting wall 41 and a second connecting wall 42 which are vertically spliced ​​with each other, the first connecting wall 41 covers the measuring surface of the inner measuring claw 3, the buckle 5 is formed on the second connecting wall 42, and a clamping area is formed between the first connecting wall 41 and the buckle 5. Specifically, the anti-wear sheet forms an L-shaped structure by combining the first connecting wall and the second connecting wall, so that the anti-wear sheet can be wrapped around the measuring claw to cover and install the measuring surface of the measuring claw.

[0023] Furthermore, a positioning pin 43 is provided on one side of the anti-wear sheet 4, and a positioning hole 44 is provided on one side of the inner measuring claw 3 corresponding to the positioning pin 43. Specifically, the positioning pin of the anti-wear sheet cooperates with the positioning hole of the inner measuring claw to achieve positioning installation of the anti-wear sheet and improve installation stability and structural strength.

[0024] Furthermore, a screw hole 45 connected to the card slot 6 is provided on one side of the inner measuring claw 3, and a machine screw 46 that can be tightly pressed against one side of the buckle 5 is connected to the inner thread of the screw hole 45. Specifically, the machine screw is moved along the screw hole to press against the buckle, so that the buckle maintains the connection state of the buckle-connected card slot, thereby realizing the fixed locking of the anti-wear sheet and preventing the anti-wear sheet from being accidentally touched and disengaged; when the anti-wear sheet needs to be disassembled and replaced, the machine screw is screwed with an external hexagonal wrench, so that the machine screw moves along the screw hole and disengages from the buckle, and then the user can press the buckle to realize the disassembly and disengagement of the anti-wear sheet.

[0025] Furthermore, one end of the buckle 5 protrudes outward from one side of the inner measuring claw 3, so that the user can press the end of the buckle to cause it to elastically deform and disengage from the buckle connection in the slot.

[0026] Furthermore, outer measuring claws 47 are fixedly connected to the main scale 1 and the vernier scale 2 respectively.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model.
