Description

Technical Field

[0001] This utility model relates to the field of building engineering testing tools, and in particular to a testing feeler gauge used in building engineering construction. Background Technology

[0002] In the field of construction, workers often need to measure the width of gaps between two walls or on the ground. If a ruler is used directly for measurement, the error will be large. In order to accurately measure the size of the gap, a feeler gauge is usually used.

[0003] Existing feeler gauges are divided into two categories: single-piece feeler gauges and wedge feeler gauges. Single-piece feeler gauges are made by inserting multiple feelers into the gap, and then reading the data by the number of feelers. Single-piece feeler gauges have a more precise structure, so wedge feeler gauges are often used for measurement in the construction field.

[0004] Currently, wedge feeler gauges are generally one-piece structures with a fixed length. If the feeler gauge is too long, it will be inconvenient to carry. If the feeler gauge is too short, when the gap is deep, one end of the feeler gauge cannot contact the bottom of the gap, making it inconvenient to store and carry. Therefore, it is necessary to propose a testing feeler gauge for construction engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a testing feeler gauge for construction engineering, in order to solve the problem mentioned in the background art that the existing testing feeler gauges for construction engineering are generally of a fixed length and are therefore inconvenient to store and carry.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeler gauge for construction engineering, comprising a feeler gauge shell, wherein a storage groove is provided inside the feeler gauge shell, the storage groove extends through the bottom and front end of the feeler gauge shell, a connecting block is slidably provided inside the storage groove, a wedge head is fixedly provided on the side of the connecting block, and a snap-fit ​​component is provided between the connecting block and the feeler gauge shell.

[0007] The snap-fit ​​assembly includes a sliding groove, which is opened on one side of the storage groove. A slider that is fixedly connected to the connecting block is slidably arranged inside the sliding groove. A support rod is fixedly arranged on the side of the slider. An L-shaped rod is fixedly arranged at each of the four corners of the support rod. A fixing seat is fixedly arranged at both ends of the feeler gauge housing near the sliding groove. Two symmetrically distributed lifting grooves are opened inside the fixing seat. A lifting block is slidably arranged inside the lifting groove. The two lifting blocks are staggered. A snap-fit ​​block is fixedly arranged on the side of the lifting block. An arc-shaped surface is provided on the side of the snap-fit ​​block away from the lifting block. A first spring is fixedly connected between the lifting block and the end of the lifting groove. The snap-fit ​​block and the fixing seat are movably fitted together.

[0008] In the initial state, the front ends of the slider and the slide groove are in contact, the L-shaped rod is locked between the corresponding locking block and the fixed seat, the lifting block is located at the end of the lifting groove, and the first spring is in a compressed state.

[0009] Preferably, the side of the snap-fit ​​block is fixedly provided with a protruding strip.

[0010] Preferably, the upper and lower ends of the fixed base are both fixedly provided with side plates, and two symmetrically distributed second springs are fixedly provided on the side of the side plate. In the initial state, the end of the second spring away from the side plate is movably attached to the L-shaped rod, and the second spring is in a compressed state.

[0011] Preferably, the wedge head is fixedly provided with a scale on its side, and the feeler gauge housing is provided with a reading component on the side away from the slide groove.

[0012] Preferably, the reading component includes a limiting groove, which is formed on the side of the feeler gauge housing away from the sliding groove. A limiting block is slidably arranged inside the limiting groove. An extension rod is fixedly arranged on the side of the limiting block. A movable rod is fixedly connected to one end of the extension rod that passes through the front end of the feeler gauge housing. The movable rod and the wedge head are in contact with each other.

[0013] Preferably, a third spring is fixedly provided on the upper and lower inner walls of the front end of the limiting groove, and a pressure plate is fixedly connected to the lower end of the third spring. The pressure plate and the extension rod are movably fitted together.

[0014] Preferably, there are several third springs located on the same side.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model, through the setting of storage groove, connecting block and snap-fit ​​component, facilitates the quick fixing of wedge head and the storage of wedge head, shortens the overall length of the test feeler gauge used in construction engineering, and solves the problem that the existing test feeler gauges used in construction engineering are generally fixed in length and are integrated structures, which are inconvenient to store and carry.

[0017] 2. By pressing the movable rod against the wall and reading the corresponding scale value, the size of the gap can be determined. The two pressure plates press the two sides of the extension rod together, increasing the friction between the extension rod and the feeler gauge housing, thus preventing the movable rod from sliding and affecting the accuracy of the reading. When not in use, the extension rod is fully retracted into the limiting groove, and the movable rod fits against the front end of the feeler gauge housing, which will not hinder the storage of the device and improve its practicality.

[0018] 3. The protruding strip allows the two locking blocks to be pushed closer together by the thumb and forefinger. At this time, the second spring recovers its elasticity and automatically pushes the L-shaped rod and the support rod a short distance. After the protruding strip is released, the locking blocks reset and will not lock the L-shaped rod again, thus improving the practicality of the device. Attached Figure Description

[0026] 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.

[0027] This utility model provides, for example Figures 1-6The invention relates to a test feeler gauge for construction engineering, comprising a feeler gauge housing 1, a storage groove inside the feeler gauge housing 1 extending through the bottom and front end of the feeler gauge housing 1, a connecting block 3 slidably disposed inside the storage groove, a wedge head 2 fixedly disposed on the side of the connecting block 3, and a snap-fit ​​assembly disposed between the connecting block 3 and the feeler gauge housing 1.

[0028] The snap-fit ​​assembly includes a slide groove 4, which is located on one side of the storage slot. Inside the slide groove 4, a slider 5 is slidably fitted and fixedly connected to the connecting block 3. A support rod 6 is fixedly fitted on the side of the slider 5. An L-shaped rod 7 is fixedly fitted at each of the four corners of the support rod 6. A fixing seat 8 is fixedly fitted at both ends of the feeler gauge housing 1 near the slide groove 4. Inside the fixing seat 8, there are two symmetrically distributed lifting grooves 9. A lifting block 10 is slidably fitted inside the lifting groove 9. The two lifting blocks 10 are staggered. A snap-fit ​​block 11 is fixedly fitted on the side of the lifting block 10. The side of the snap-fit ​​block 11 away from the lifting block 10 has an arc-shaped surface. A first spring 12 is fixedly connected between the ends of the lifting block 10 and the lifting groove 9. The snap-fit ​​block 11 and the fixing seat 8 are movably fitted together.

[0029] Specifically, in use, in the initial state, the front ends of the slider 5 and the slide groove 4 are in contact, the L-shaped rod 7 is stuck between the corresponding snap block 11 and the fixed seat 8, the lifting block 10 is located at the end of the lifting groove 9, and the first spring 12 is under pressure, thereby fixing the support rod 6, the slider 5 and the connecting block 3, so that the wedge head 2 is fixed at the front end of the feeler gauge housing 1, which facilitates the normal use of the test feeler gauge used in construction engineering.

[0030] After use, push the two locking blocks 11 closer together to displace them, causing the locking blocks 11 to release their engagement with the L-shaped rod 7. This facilitates pushing the L-shaped rod 7 and the support rod 6 backward, which in turn moves the slider 5 and the connecting block 3 backward, allowing the wedge head 2 to be stored inside the storage slot. At this point, the L-shaped rod 7 touches the arc-shaped surface of the locking block 11 located behind it, forcing the locking block 11 to move. This allows the L-shaped rod 7 to pass smoothly through the locking block 11. Then, the first spring 12 regains its elasticity, pushing the lifting block 10 and the locking block 11 to move, locking the L-shaped rod 7 between the corresponding locking block 11 and the fixing seat 8, quickly completing the fixation of the wedge head 2. When needed, similarly, the wedge head 2 can be quickly fixed to the front end of the feeler gauge housing 1.

[0031] In summary, this utility model, through the design of the storage slot, connecting block 3, and snap-fit ​​component, facilitates the quick fixing of the wedge head 2 while also making it easy to store the wedge head 2, thus shortening the overall length of the feeler gauge used in construction engineering. This solves the problem that existing feeler gauges used in construction engineering are generally fixed-length integrated structures, making them inconvenient to store and carry.

[0032] Furthermore, a protrusion 13 is fixedly provided on the side of the snap-fit ​​block 11. The protrusion 13 makes it easy to push the two snap-fit ​​blocks 11 closer to each other with the thumb and forefinger, thereby making it easier to push the L-shaped rod 7 and the support rod 6 to move, and thus quickly release the fixation of the wedge head 2.

[0033] Furthermore, side plates 14 are fixedly installed at both the upper and lower ends of the fixed base 8. Two symmetrically distributed second springs 15 are fixedly installed on the side of the side plate 14. In the initial state, the end of the second spring 15 away from the side plate 14 is in contact with the L-shaped rod 7 and the second spring 15 is under pressure. After the two locking blocks 11 are pushed closer to each other by the thumb and forefinger, the second spring 15 recovers its elasticity and automatically pushes the L-shaped rod 7 and the support rod 6 to a small distance. After the protrusion 13 is released, the locking block 11 resets and will not lock the L-shaped rod 7 again, thus improving the practicality of the device.

[0034] Furthermore, the wedge head 2 is fixedly provided with a scale on its side, and the feeler gauge housing 1 is provided with a reading component on the side away from the slide groove 4.

[0035] The reading assembly includes a limiting groove 16, which is located on the side of the feeler gauge housing 1 away from the slide groove 4. A limiting block 17 is slidably arranged inside the limiting groove 16. An extension rod 18 is fixedly arranged on the side of the limiting block 17. A movable rod 19 is fixedly connected to one end of the extension rod 18 that passes through the front end of the feeler gauge housing 1. The movable rod 19 and the wedge head 2 are in contact with each other. A third spring 20 is fixedly arranged on the upper and lower inner walls of the front end of the limiting groove 16. A pressure plate 21 is fixedly connected to the lower end of the third spring 20. The pressure plate 21 and the extension rod 18 are in contact. Several third springs 20 are arranged on the same side.

[0036] Specifically, by pressing the movable rod 19 against the wall and reading the corresponding scale value of the movable rod 19, the size of the gap can be determined. The two pressure plates 21 press the two sides of the extension rod 18, increasing the friction between the extension rod 18 and the feeler gauge housing 1, thereby preventing the movable rod 19 from sliding and affecting the accuracy of the value. When not in use, the extension rod 18 is fully retracted into the limiting groove 16, and the movable rod 19 fits against the front end of the feeler gauge housing 1, without hindering the storage of the device and improving the practicality of the device.

[0037] Working principle: In the initial state, the front ends of the slider 5 and the slide groove 4 are in contact, the L-shaped rod 7 is locked between the corresponding locking block 11 and the fixed seat 8, the lifting block 10 is located at the end of the lifting groove 9, and the first spring 12 is under pressure. This fixes the support rod 6, slider 5, slide groove 4 and connecting block 3, thereby fixing the wedge head 2 to the front end of the feeler gauge housing 1, facilitating the normal use of the feeler gauge for construction engineering. After use, the two locking blocks 11 located in front are pushed closer together by the thumb and forefinger. At this time, the second spring 15 recovers its elasticity, automatically pushing the L-shaped rod 7 and the support rod 6 a small distance, and then releasing the protrusion 13. The locking block 11 then resets and will not interfere with the L-shaped rod 10 again. The L-shaped rod 7 is engaged, which facilitates the push of the L-shaped rod 7 and the support rod 6 to move backward, thereby driving the slider 5 and the connecting block 3 to move backward, and storing the wedge head 2 inside the storage groove. At this time, the L-shaped rod 7 touches the arc surface of the locking block 11 located behind, forcing the locking block 11 to move, so that the L-shaped rod 7 can pass smoothly through the locking block 11. Then the first spring 12 returns to its elasticity, pushing the lifting block 10 and the locking block 11 to move, locking the L-shaped rod 7 between the corresponding locking block 11 and the fixing seat 8, quickly completing the fixing of the wedge head 2, realizing the quick storage and fixing of the wedge head 2, shortening the overall length of the test feeler gauge used in the construction project, making it easy to carry. When needed, the wedge head 2 can be quickly fixed to the front end of the feeler gauge shell 1.

[0038] In addition, during use, the size of the gap can be determined by pressing the movable rod 19 against the wall and reading the corresponding scale value of the movable rod 19. The two pressure plates 21 press the two sides of the extension rod 18 to increase the friction between the extension rod 18 and the feeler gauge housing 1, thereby preventing the movable rod 19 from sliding and affecting the accuracy of the value. When not in use, the extension rod 18 is fully retracted into the limiting groove 16, and the movable rod 19 fits against the front end of the feeler gauge housing 1, without obstructing the storage of the device.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
