Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a feeler gauge for building engineering measurement. Background Technology

[0002] In the field of building engineering surveying, measuring the gaps between components is a crucial step in ensuring construction accuracy and project quality. Feeler gauges, as tools specifically designed for measuring gaps, are widely used in steel structure connections, wall construction, equipment installation, and other scenarios. However, with the increasing demands for construction precision in modern buildings, the operational convenience and measurement accuracy issues exposed by traditional feeler gauges have become increasingly apparent. To better meet the gap measurement needs in complex environments within building engineering projects and to improve measurement efficiency and data reliability, the development of a new type of feeler gauge for building engineering surveying has become an important direction for optimizing measurement tools within the industry.

[0003] Conventional feeler gauges in current technology typically consist of a set of thin plates of varying thicknesses, usually made of stainless steel, which offers good rigidity and wear resistance. One edge of each plate is engraved with corresponding thickness markings, allowing the user to select the appropriate thickness based on the estimated gap size. The measurement principle determines the gap size by the degree of matching between the actual thickness of the plate and the gap – if the plate inserts smoothly without significant looseness, the plate thickness is an approximation of the gap; if it inserts too tightly or is difficult to insert, a thinner or thicker plate should be used. Additionally, some feeler gauges integrate the plates into a handle, allowing for easy access and storage through sliding or folding.

[0004] However, conventional feeler gauges in the existing technology have fixed sheet thickness specifications, while the actual gap size measured in construction engineering is often continuously changing. When the gap size is between the thicknesses of two adjacent sheet specifications, it is difficult to accurately measure the precise value of the gap directly using a single sheet. Only a rough range can be obtained, resulting in low accuracy of the measurement results, which is difficult to meet the measurement requirements of high-precision construction. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a feeler gauge for construction engineering measurement, which aims to improve the problem of needing tools to measure when working at high altitudes and low places.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeler gauge for measuring in construction engineering, comprising a handle one, a handle two slidably connected to the outer wall of the handle one, a slot one inside the handle one, a slot two inside the handle two, a connecting post one fixedly connected to the outer wall of the handle one, and a fixing component inside the connecting post one.

[0007] The fixing component includes a pressing post, the outer wall of which is slidably connected to the inside of a connecting post. A spring is sleeved on the outer wall of the pressing post, one end of which is fixedly connected to the inner wall of the connecting post. A fixing post is fixedly connected inside the connecting post. A slot three is formed inside the fixing post. A rotating groove is formed inside the fixing post. A limiting post is slidably connected to the inner wall of the slot three. A limiting block is fixedly connected to the outer wall of the limiting post, and the outer wall of the limiting block is rotatably connected to the inner wall of the fixing post.

[0008] Furthermore, a limiting post two is slidably connected to the inner wall of the card slot one, a connecting block one is fixedly connected to the outer wall of the limiting post two, and a connecting block four is fixedly connected to the outer wall of the connecting block one.

[0009] Furthermore, a rotating shaft is rotatably connected to the inner wall of the connecting block four, and a fixing block is rotatably connected to the outer wall of the rotating shaft one.

[0010] Furthermore, a second rotating shaft is rotatably connected to the inner wall of the first fixed block, and a second connecting block is rotatably connected to the outer wall of the second rotating shaft.

[0011] Furthermore, a slot four is provided inside the handle two, and a fixing block two is fixedly connected to the inner wall of the handle two.

[0012] Furthermore, a connecting block three is fixedly connected to the outer wall of the connecting block two, and the outer wall of the connecting block three is slidably connected to the inner wall of the fixed block two.

[0013] Furthermore, a spring is fixedly connected to the outer wall of the connecting block three, and one end of the spring is fixedly connected to the inside of the handle two.

[0014] Furthermore, a connecting column two is fixedly connected to the outer wall of the pressing column one, and a feeler gauge one is fixedly connected inside the connecting column two.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, by pressing down on the pressing post, the spring is deformed in the connecting post. At this time, the pressing post drives the limiting block downward and causes the limiting post on the limiting block to disengage from the slot three and into the rotating groove. The limiting post can then rotate in the rotating groove. When it rotates to the appropriate position, the pressing post is released, and the spring releases its pressure and returns to its original position, causing the connecting post to spring back. This allows for quick positioning of the feeler gauge.

[0017] In this utility model, by pressing down on connecting block 2, connecting block 3 can be limited to move within the fixed block. At this time, the spring on connecting block 3 is deformed by force, and connecting block 4 and connecting block 2 connected by rotating shaft 2 drive connecting block 4 to rotate through rotating shaft 1. Because rotating shaft 1 is fixed by fixed block 1, it drives connecting block 1 to move upward, thereby causing limiting post 2 to disengage from slot 1, thus achieving the adjustment of the handle length.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3An embodiment of this utility model provides: a feeler gauge for measuring in construction engineering, including a handle 1, a handle 4 connected to a connecting post 6, a handle 4 slidably connected to the outer wall of the handle 1, a slot 3 inside the handle 1 for fixing the handle 1 and the handle 4, a slot 5 inside the handle 4 for sliding on the outer wall of the handle 1 to achieve a fixing effect, and a connecting post 6 fixedly connected to the outer wall of the handle 1, with a fixing component inside the connecting post 6;

[0027] The fixing component includes a pressing post 8, which is a pressable columnar component. When force is applied, it pushes the internal structure to realize the opening and closing. The outer wall of the pressing post 8 is slidably connected to the inside of the connecting post 6. A spring 9 is sleeved on the outer wall of the pressing post 8. The spring 9 is a mechanical part that uses elastic deformation to realize energy storage and release. It deforms when force is applied and returns to its original shape after the force is released. One end of the spring 9 is fixedly connected to the inner wall of the connecting post 6. A fixing post 10 is fixedly connected inside the connecting post 6. The limiting post 13 is fixed through the fixing post 10, the rotating groove 14 therein, and the locking groove 11. The locking groove 11 and the rotating groove 14 are opened inside the fixing post 10. The limiting post 13 is slidably connected to the inner wall of the locking groove 11. The limiting block 12 is fixedly connected to the outer wall of the limiting post 13. By rotating the limiting block 12, the feeler gauge 2 is controlled to not shake during measurement. The outer wall of the limiting block 12 is rotatably connected to the inner wall of the fixing post 10.

[0028] Reference Figures 1-5The inner wall of slot 13 is slidably connected to limit post 2 15. The overall length is controlled by the limit post 2 15 being engaged in slot 13. The outer wall of limit post 2 15 is fixedly connected to connecting block 1 16, which connects connecting block 4 25 and limit post 2 15. The outer wall of connecting block 1 16 is fixedly connected to connecting block 4 25, which in turn connects to rotating shaft 17. The inner wall of connecting block 4 25 is rotatably connected to rotating shaft 17, which causes fixed block 1 19 and connecting block 4 25 to rotate on their outer wall. The outer wall of rotating shaft 17 is rotatably connected to fixed block 19, and the inner wall of fixed block 1 19 is rotatably connected to rotating shaft 2 18, which causes connecting block 4 25 and connecting block 2 20 to rotate on their outer wall. The outer wall of rotating shaft 2 18 is rotatably connected to connecting block 2 20, which connects to connecting block 3 21. The handle 24 has a slot 4 2 inside. 4. The spring 23 is fixed inside the slot 424. The inner wall of the handle 24 is fixedly connected to the fixing block 22, which restricts the displacement direction of the connecting block 31. The outer wall of the connecting block 20 is fixedly connected to the connecting block 31. The outer wall of the connecting block 321 is slidably connected to the inner wall of the fixing block 22. The outer wall of the connecting block 321 is fixedly connected to the spring 23. The spring 23 is a mechanical part that uses elastic deformation to realize energy storage and release. It deforms when subjected to force and returns to its original shape after the force is released. One end of the spring 23 is fixedly connected to the inside of the handle 24. The outer wall of the pressing column 18 is fixedly connected to the connecting column 27. The feeler gauge 12 is fixedly connected inside the connecting column 27. The feeler gauge 12 is a thin sheet measuring tool for measuring gaps. It consists of a set of steel sheets of different thicknesses and is marked with thickness values. When measuring, a suitable steel sheet is inserted into the gap, and the size is judged by the tightness. It is used for gap detection in machinery, molds, etc.

[0029] Working principle: When using a feeler gauge to measure construction projects, the operator first presses down on the pressing post 8 with their finger. At this time, the spring 9 inside the connecting post 6 connected to the pressing post 8 immediately receives axial pressure and begins to contract and deform along the axial direction. Under the deformation transmission of the spring 9, the pressing post 8, along with the bottom limiting block 12, moves smoothly downwards. The limiting post 13 on the limiting block 12 also moves synchronously. During this process, the limiting post 13 gradually disengages from the originally tightly fitted slot 3 11. After completely disengaging from the slot 3 11, it enters the preset rotating groove 14. The annular channel designed to fit the limiting post 13 in the fixed post 10 allows the limiting post 13 to rotate flexibly within it. The operator can rotate it to the precise position according to the required angle of use of the feeler gauge 2. After rotating to the appropriate position, the pressing post 8 is released, and the spring 9, which was previously in a contracted state, will quickly release the stored elastic pressure and return to its original state. Under the reset force of the spring 9, the connecting post 6 is bounced back to the initial position, and the limiting block 12 is also reset. The limiting post 13 then re-engages into the corresponding slot 11, thereby completing the rapid positioning of the feeler gauge 2 and ensuring stable position during subsequent use.

[0030] Secondly, by pressing down on connecting block 20, connecting block 20 will cause connecting block 3 21 to move within the slot 4 24 of fixing block 22. Spring 23 on connecting block 3 21 will deform under pressure, storing elastic potential energy. As connecting block 20 moves downward, connecting block 4 25, connected to it via rotating shaft 2 18, will move downward synchronously, causing connecting block 4 25 to rotate around rotating shaft 1 17. Since rotating shaft 1 17 is firmly fixed to the equipment body by fixing block 1 19, it cannot move. The rotation of connecting block 4 25 will drive connecting block 1 16 to move upward through the linkage structure. When connecting block 1 16 moves upward, the limiting post 2 15 at its end will gradually disengage from the original locking groove 1 3. The groove 1 3 consists of multiple grooves evenly distributed, corresponding to different length positions of the handle. When the limiting post 2 15 completely disengages from the groove 1 3, the handle 1 1 and handle 2 4 are released from the length locking state and can be extended and retracted through the groove 2 5 on handle 2 4. The operator can freely extend or shorten according to the grip comfort to adjust the length.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
