Description

Technical Field

[0001] The present invention relates to the technical field of engineering surveying and mapping, and particularly to a measuring tool for engineering construction materials. Background Art

[0002] Engineering construction is a comprehensive and complex task, which involves multiple links such as planning, design, construction and post-maintenance. Through careful planning and scientific management, engineers turn blueprints into reality and build infrastructure such as high-rise buildings, roads and bridges. Engineering construction materials refer to the material basis for various engineering constructions, including but not limited to wood, stone, cement, concrete, steel, glass, ceramics, composite materials, etc. The selection and use of these materials directly affect the quality, safety, durability and economy of the project. Through measuring tools, the dimensions, positions, angles, etc. of buildings can be accurately determined to ensure that the construction meets the design requirements. Measuring tools can monitor the structural stability of buildings, timely detect potential safety hazards and ensure construction safety. Measuring tools play a crucial role in engineering construction.

[0003] In existing engineering buildings, in order to facilitate drainage or install drainage pipes, various specifications of reserved holes need to be pre-made during engineering construction. However, when measuring the holes of the project, only the diameter of the holes can be simply measured on the surface of the holes by a measuring ruler, which easily affects the measurement accuracy and it is not easy to measure the internal situation of the holes, resulting in difficult accurate measurement of the inside of the holes and affecting the later use of the holes. Therefore, a measuring tool for engineering construction materials is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when measuring the holes of a project, only the diameter of the holes can be simply measured on the surface of the holes by a measuring ruler, which easily affects the measurement accuracy and it is not easy to measure the internal situation of the holes, resulting in difficult accurate measurement of the inside of the holes, and to propose a measuring tool for engineering construction materials.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A measuring tool for engineering construction materials, comprising a housing. A display screen is fixedly connected to the upper part of the housing. A measuring component is arranged on the housing. The measuring component includes a plurality of measuring rods and balls movably connected to the outside of the housing, as well as a spring and a movable rod movably connected to the inside of the housing. When the movable rod is pulled outwards, it drives the plurality of measuring rods and balls to retract inwards at the same time. The retracted measuring rods and balls are put into the hole to be measured through the housing. When the outwardly pulled movable rod is released, the spring rebounds the movable rod, causing the movable rod to drive the plurality of measuring rods and balls to expand outwards, so as to measure the inner side of the hole. An auxiliary component is arranged on the outside of the housing. The auxiliary component includes a plurality of limit blocks movably connected to the outside of the housing, and a threaded sleeve rotatably connected to the outside of the housing. The limit blocks are placed inside the hole to be measured. By rotating the threaded sleeve, the threaded sleeve squeezes the plurality of limit blocks, causing the limit blocks to expand outwards at the same time, so that the whole device is fixed at the center position of the hole.

[0007] The above technical solution further includes:

[0008] A plurality of sensors are fixedly connected to the outside of the housing. A handle is fixedly connected to the bottom of the housing. A plate is movably connected inside the handle. The plate is movably connected to the movable rod. By pressing the plate with hand, the plate drives the movable rod to move inside the housing.

[0009] The movable rod is fixedly connected to the spring. An annular rack is fixedly connected to the end of the movable rod away from the handle. A plurality of fixing blocks are fixedly connected to the outside of the housing. When the movable rod moves outwards, it squeezes the spring, and the spring rebounds the movable rod to return to its original position.

[0010] A fixing rod is fixedly connected to the outside of the fixing block. A gear is rotatably connected to the outside of the fixing rod. The gear is meshed with the annular rack. The movement of the movable rod drives the gear to rotate inwards through the annular rack.

[0011] The gear is fixedly connected to the measuring rod. The measuring rod is movably connected to the ball. The inward rotation of the gear drives the measuring rod and the ball to contract inwards.

[0012] A plurality of sliding grooves are formed on the side surface of the housing. A first annular shell is movably connected to the outside of the housing. A plurality of sliders are fixedly connected to the inside of the first annular shell. The sliders slide inside the sliding grooves, restricting the movement direction of the first annular shell.

[0013] The slider is slidably connected to the sliding groove. The opening size of the sliding groove is adapted to the size of the slider. The slider fits inside the sliding groove, so that the sliding groove restricts the slider.

[0014] A threaded groove is provided on the side surface of the first annular shell. A second annular shell is movably connected to the outside of the first annular shell. The threaded sleeve shell is threadedly connected to the threaded groove, and the rotation of the threaded sleeve shell causes it to move through the threaded groove.

[0015] A plurality of support plates are fixedly connected to the outside of the threaded sleeve shell. Card slots are provided on the side surfaces of the plurality of support plates. A plurality of support blocks are fixedly connected to the outside of the second annular shell. The rotation of the threaded sleeve shell drives the support plates to squeeze the clamping blocks, causing the clamping blocks to slide within the card slots.

[0016] The outside of the support block is symmetrically and movably connected with connecting rods. The connecting rods are movably connected to the limiting blocks. Clamping blocks are fixedly connected to the outside of the connecting rods. The clamping blocks are slidably connected to the card slots. The support plates squeeze the limiting blocks as the threaded sleeve shell rotates, causing the limiting blocks to expand outwards.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, multiple measuring rods and balls in the measuring assembly are retracted and placed in the measured hole, and the measuring rods and balls expand outwards due to the rebound of the spring, thereby measuring the inside of the hole, so as to achieve all-round and high-precision measurement of the inside of the hole. It can also effectively avoid the errors caused by the traditional measurement method that only measures the surface diameter, ensure the accuracy of the hole measurement, and provide a strong guarantee for subsequent engineering construction.

[0019] 2. In the present invention, multiple limiting blocks in the auxiliary assembly expand outwards synchronously, which can quickly and stably fix the entire measuring device at the center position of the reserved hole, ensure that the device does not shift during measurement, thereby achieving more accurate and comprehensive measurement of the inside of the hole, effectively solving the measurement error problem caused by the instability of the device in the traditional measurement method, and improving the measurement efficiency and accuracy.

[0028] 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.

[0029] Embodiment 1

[0030] As Figures 1-7 shown, a measuring tool for engineering construction materials proposed by the present invention includes a housing 1. A display screen 4 is fixedly connected to the upper part of the housing 1. A measuring component is arranged on the housing 1. The measuring component includes a plurality of measuring rods 5 and balls 6 movably connected to the outside of the housing 1, and a spring 12 and a movable rod 11 movably connected to the inside of the housing 1. Pulling the movable rod 11 outwards drives the plurality of measuring rods 5 and balls 6 to simultaneously retract inwards. Through the housing 1, the retracted measuring rods 5 and balls 6 are placed into the hole to be measured. Releasing the pulled-out movable rod 11, the spring 12 rebounds the movable rod 11, so that the movable rod 11 drives the plurality of measuring rods 5 and balls 6 to expand outwards, and then the inner side of the hole can be measured. An auxiliary component is arranged on the outside of the housing 1. The auxiliary component includes a plurality of limiting blocks 23 movably connected to the outside of the housing 1, and a thread sleeve housing 19 rotatably connected to the outside of the housing 1. The limiting blocks 23 are placed inside the hole to be measured. By rotating the thread sleeve housing 19, the thread sleeve housing 19 squeezes the plurality of limiting blocks 23, so that the limiting blocks 23 expand outwards simultaneously, and the whole device is fixed at the central position of the hole.

[0031] A plurality of sensors 7 are fixedly connected to the outside of the housing 1. A grip 2 is fixedly connected to the bottom of the housing 1. A plate 3 is movably connected inside the grip 2. The plate 3 is movably connected to the movable rod 11. By pressing the plate 3 with the hand, the plate 3 drives the movable rod 11 to move inside the housing 1.

[0032] The movable rod 11 is fixedly connected to the spring 12. One end of the movable rod 11 away from the grip 2 is fixedly connected with an annular rack 13. A plurality of fixed blocks 8 are fixedly connected to the outside of the housing 1. The movable rod 11 moves outward to compress the spring 12, and the spring 12 rebounds to make the movable rod 11 return to its original position.

[0033] A fixed rod 10 is fixedly connected to the outside of the fixed block 8. A gear 14 is rotatably connected to the outside of the fixed rod 10. The gear 14 meshes with the annular rack 13. The movement of the movable rod 11 drives the gear 14 to rotate inward through the annular rack 13.

[0034] The gear 14 is fixedly connected to the measuring rod 5. The measuring rod 5 is movably connected to the ball 6. The inward rotation of the gear 14 drives the measuring rod 5 and the ball 6 to contract inward.

[0035] In this embodiment, by holding the grip 2 with the hand and pressing the plate 3 with the finger, the plate 3 drives the movable rod 11 to pull outward. The pulled movable rod 11 compresses the spring 12, and the movable rod 11 drives a plurality of measuring rods 5 and balls 6 to contract inward simultaneously through the annular rack 13 and the gear 14. At this time, the housing 1 can be driven by the grip 2 to place the measuring rods 5 and the balls 6 into the holes to be measured. Release the pressed plate 3, and the compressed spring 12 rebounds the movable rod 11, so that the movable rod 11 drives a plurality of measuring rods 5 and balls 6 to expand outward, making the balls 6 fit against the inner wall of the hole. The sensor 7 enables the display screen 4 to display the measured value in real time to ensure the accuracy of the hole measurement.

[0036] Embodiment Two

[0037] As Figures 1-7 shown, based on Embodiment One, a plurality of sliding grooves 9 are formed on the side surface of the housing 1. The outside of the housing 1 is movably connected with a first annular shell 15. A plurality of sliders 16 are fixedly connected to the inside of the first annular shell 15. The sliders 16 slide inside the sliding grooves 9 to limit the movement direction of the first annular shell 15.

[0038] The slider 16 is slidably connected to the sliding groove 9. The opening size of the sliding groove 9 is adapted to the size of the slider 16. The slider 16 fits inside the sliding groove 9, so that the sliding groove 9 restricts the slider 16.

[0039] A threaded groove 17 is formed on the side surface of the first annular shell 15. The outside of the first annular shell 15 is movably connected with a second annular shell 18. A threaded sleeve 19 is threadedly connected to the threaded groove 17. The rotation of the threaded sleeve 19 moves through the threaded groove 17.

[0040] A plurality of support plates 20 are fixedly connected to the outer side of the threaded casing 19 , and slots 22 are provided on the sides of the plurality of support plates 20 . A plurality of support blocks 24 are fixedly connected to the outer side of the second annular casing 18 . The rotation of the threaded casing 19 drives the support plates 20 to squeeze the blocks 21 , causing the blocks 21 to slide in the slots 22 .

[0041] The outer side of the support block 24 is symmetrically and movably connected with a connecting rod 25, and the connecting rod 25 is movably connected to the limit block 23. The outer side of the connecting rod 25 is fixedly connected with a clamping block 21, and the clamping block 21 is slidably connected to the clamping groove 22. The support plate 20 squeezes the limit block 23 as the threaded sleeve 19 rotates, so that the limit block 23 expands outward.

[0042] In this embodiment, through the description in the previous step, the first annular shell 15 is placed into the hole, and the support plate 20 is moved to drive the threaded shell 19 to rotate. The threaded shell 19 slides on the first annular shell 15 through the thread groove 17. At this time, the rotation of the support plate 20 drives the second annular shell 18 to follow the rotation. As the threaded shell 19 rotates, the support plate 20 drives the connecting rod 25 to squeeze the block 21 at the end of the connecting rod 25 to slide in the groove 22, and the connecting rod 25 expands outward with the squeezing of the support plate 20, thereby fixing the port inside the hole, fixing the measuring component at the center of the hole, and allowing the measuring component to move back and forth on the first annular shell 15, thereby improving the measurement accuracy of the hole.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
