Technical Field
[0001] The utility model relates to the technical field of construction engineering measurement, in particular to a construction engineering measurement device. Background Art
[0002] With the ever-increasing pursuit of measurement accuracy and efficiency in modern construction engineering, the continuous innovation and optimization of measurement tools is becoming increasingly important. Traditional measurement devices often utilize simple spring-driven recovery systems. During the measurement process, the stability and recovery speed of the scale bar are often difficult to effectively control, affecting the accuracy of measurement results and the lifespan of the equipment.
[0003] In some complex measurement environments, external forces and environmental factors may cause the scale bar to become unstable during the measurement process. In particular, when the scale bar is pulled out, if it cannot be effectively fixed, it may accidentally retract due to interference from external forces or the reaction force of the recovery spring. In addition, due to the rapid recovery of the scale bar, traditional measuring devices are also prone to equipment wear during use or potential safety hazards due to excessive recovery speeds, especially under harsh working conditions. Utility Model Content

[0014] Beneficial effects of the utility model:
[0015] 1. This construction engineering measurement device is equipped with an anti-slip component. When the ruler is pulled out, the ratchet is pressed toward one side of the fixed disk by the action of the pressure spring, and the ratchet engages with the slot to keep the ratchet in a locked state, thereby preventing the ruler from retracting into the shell due to external force or the action of the internal recovery spring. A slot is provided inside the ratchet disk to match the ratchet on the fixed disk to form a one-way locking structure, so that the device can adapt to a variety of complex measurement environments, ensuring that the ruler remains stable in the pulled-out state, greatly improving the measurement accuracy and reliability. In addition, the device also effectively avoids potential injuries and equipment wear caused by the rapid recovery of the ruler, thereby extending the service life of the device and providing users with a safe, durable and efficient measuring tool.
[0016] 2. This type of construction engineering measurement device is equipped with a locking assembly. When the push plate is pressed, the sliding column drives the ratchet plate to move along the sliding path, so that the ratchet plate disengages from the ratchet on the fixed plate and releases the engagement between the ratchet and the slot. At this time, the ruler can be smoothly recovered into the shell under the drive of the internal recovery spring. When the push plate is released, the return spring pushes the locking block to return to its initial position, so that the locking block re-engages with the lock slot and re-locks the lock column in its original position, thereby ensuring that the locking assembly returns to the locked state.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0030] like Figures 1 to 8 As shown, the construction engineering measurement device includes: a housing 1, a ruler 2 is installed in the housing 1, and a blocking plate 3 is installed on one side of the housing 1; an anti-slip component, which is installed inside the housing 1 and is used to prevent the ruler 2 from being quickly retracted during use; a locking component, which is installed in the anti-slip component and is used to trigger the anti-slip component; an anti-slip pad is installed on the side of the blocking plate 3 close to the ruler 2;
[0031] During use, the anti-slip component and the locking component work together to control the operating state of the ruler 2. The anti-slip component is installed inside the shell 1. Its main function is to ensure that the ruler 2 will not retract into the shell 1 due to spring rebound or external force interference during the pulling process, so as to avoid the ruler 2 accidentally injuring the operator during the recovery process. The anti-slip component provides resistance to the ruler 2 through a specific one-way restriction structure to ensure that it can remain stable when pulled out, thereby meeting the measurement needs. When the ruler 2 needs to be recovered, the locking component is operated. The function of the locking component is to release the restriction of the anti-slip component on the ruler 2. At the same time, the anti-slip pad installed on one side of the blocking plate 3 further enhances the friction by contacting the surface of the ruler 2, effectively preventing the ruler 2 from sliding in the non-operating state, thereby ensuring that the device is safer and more reliable during the measurement and recovery process.
[0032] like Figures 2 to 4 As shown, the anti-slip assembly includes a fixed disk 4 fixedly mounted on one side of the interior of the housing 1, a through hole 5 is opened in the middle of the fixed disk 4, a ratchet 16 is installed on one side of the fixed disk 4, a ratchet disk 17 is movably installed in the housing 1, a slot 15 is opened in the ratchet disk 17, and the slot 15 is adapted to the ratchet 16; a ruler spring 14 is installed on the outer circumference of the ratchet disk 17, the outer side of the ruler spring 14 is in contact with the inner circumference of the ruler bar 2, a pressure spring 13 is installed on the side of the ratchet disk 17 away from the fixed disk 4, and the side of the pressure spring 13 away from the ratchet disk 17 is installed on the side of the housing 1;
[0033] When the ruler 2 is pulled out, the fixed disk 4 fixedly installed on one side of the inner part of the shell 1 provides support and guidance for the ruler 2 through the through hole 5 opened in the middle thereof. A slot 15 is opened inside the ratchet disk 17, and the slot 15 is adapted to the ratchet 16 on the fixed disk 4 to form a one-way locking structure. When the ruler 2 is pulled out, the ratchet disk 17 is pressed toward one side of the fixed disk 4 under the action of the pressure spring 13, and the ratchet 16 engages with the slot 15, so that the ratchet disk 17 remains in a locked state, thereby preventing the ruler 2 from retracting into the inner part of the shell 1 due to external force or the action of the internal recovery spring.
[0034] like Figures 5 to 8 As shown, the locking assembly includes a pressing plate 11 installed on the outside of the shell 1, and a plurality of sliding posts 12 are installed on the side of the pressing plate 11 close to the shell 1. The plurality of sliding posts 12 pass through the shell 1 and extend, and a ratchet disk 17 is commonly installed on the extended ends of the plurality of sliding posts 12. A lock column 10 is installed in the middle of the pressing plate 11, and the lock column 10 is adapted to the through hole 5. Two locking blocks 8 are symmetrically installed on the outer circumference of the lock column 10, and two sliders 9 are symmetrically installed on the outer circumference of the lock column 10; a plurality of locking grooves 6 are provided in the through hole 5, and the plurality of locking grooves 6 are adapted to the locking blocks 8, and two sliding grooves 7 are symmetrically provided in the through hole 5, and the two sliding grooves 7 are adapted to the sliders 9, and the sliders 9 are slidably installed in the sliding grooves 7; a sliding groove 19 is provided inside the lock column 10, and the lock block 8 is slidably installed in the sliding groove 19, and a return spring 18 is fixedly installed between the two lock blocks 8. The cross section of the lock block 8 is triangular, and the inclined surface of the lock block 8 is away from the pressing plate 11;
[0035] When the operator presses the push plate 11, the slide column 12 drives the ratchet 17 to move along the sliding path, so that the ratchet 17 disengages the ratchet 16 on the fixed plate 4, and releases the meshing state of the ratchet 16 and the card slot 15. At this time, the ruler 2 can be smoothly recovered to the inside of the housing 1 under the drive of the internal recovery spring. In the initial state, the return spring 18 pushes the locking block 8 outward, so that the locking block 8 engages with the several locking grooves 6 inside the through hole 5, thereby locking the lock column 10 in the specified position. When the operator presses the push plate 11, the locking block 8 is squeezed and retracted into the sliding groove 19, thereby releasing the lock on the lock column 10. When the lock is unlocked, the slider 9 slides in the two slide grooves 7 inside the through hole 5, further pushing the lock column 10 to the unlocked position, so that the locking assembly completes the unlocking operation. In the unlocked state, the ratchet plate 17 moves under the drive of the slide column 12, disengages the ratchet 16 on the fixed plate 4, and releases the one-way locking function of the ruler 2, so that the ruler 2 can be smoothly recovered into the shell 1. When the push plate 11 is released, the return spring 18 pushes the lock block 8 to return to the initial position, so that the lock block 8 re-engages with the lock groove 6, and re-locks the lock column 10 in the original position, thereby ensuring that the locking assembly returns to the locked state, facilitating the next operation.
