Description

Technical Field

[0001] This utility model belongs to the field of construction engineering technology, specifically, it relates to a construction engineering measurement device. Background Technology

[0002] Surveying is a crucial part of the construction process, providing accurate data support for the design, construction, and acceptance of the project.

[0003] Chinese Patent Publication No. CN220750981U discloses a construction engineering measuring device, including a measuring tape, a housing, and a pressing assembly. The pressing assembly includes a connecting chamber, a hollow column, a spring, a scraper, a round rod, a pressing rod, a frosted pad, and a pressing block. The housing has a slotted hole, and a measuring tape is rotatably disposed inside the housing. The output end of the measuring tape passes through the slotted hole. The connecting chamber is fixedly connected to the housing and located on the slotted hole. The connecting chamber has a round hole that slides with the round rod. One end of the spring is fixedly connected to the connecting chamber and located inside the hollow column. The pressing rod is slidably connected to the hollow column and located inside the hollow column. A spring runs through one end of the round rod. When retracting the measuring tape, pressing the pressing block with your hand compresses the spring, causing the round rod to slide within the round hole. This causes the abrasive pad under the scraper to contact the measuring tape, thus controlling the speed of tape retraction and reducing the risk of injury to the operator. However, retracting the measuring tape requires continuous pressing of the pressing block to slow down the tape through friction between the abrasive pad and the measuring tape. If the operator uses only one hand (e.g., the other hand needs to hold the end of the measuring tape), prolonged pressing may cause hand fatigue, especially when retracting the measuring tape frequently, which can affect efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a construction engineering surveying device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A construction engineering surveying device includes: a housing with a strip-shaped hole on its side wall; a measuring tape connected inside the housing, with the output end of the measuring tape passing through the strip-shaped hole; a fixing box connected to the top of the strip-shaped hole; a pressure plate at the top of the fixing box; a connecting post at the bottom of the pressure plate; the connecting post passing through the top of the fixing box; and a pressure block at the other end of the connecting post; the bottom end of the pressure block passing through the top of the strip-shaped hole and abutting against the measuring tape; and adjusting components connected to the left and right sides inside the fixing box, with the pressure block fixed by the adjusting components.

[0008] Optionally, the adjustment assembly includes a connecting plate that abuts against the inner walls of the left and right sides of the fixed box. A slider is connected to one side of the connecting plate that abuts against the inner wall of the fixed box, and a limit plate is connected to the other side through the connecting assembly.

[0009] Optionally, the limiting plate abuts against the side wall of the lower pressing block, and the side wall of the limiting plate is provided with a toothed groove, and the side wall of the lower pressing block is provided with teeth corresponding to the toothed groove.

[0010] Optionally, the left and right side walls of the fixing box are provided with grooves corresponding to the slider, the slider is located in the grooves, and the side wall of the slider is connected to a sliding plate.

[0011] Optionally, the connecting assembly includes a fixed post and a connecting rod. One end of the fixed post is fixedly connected to the side wall of the connecting plate, and one end of the connecting rod is fixedly connected to the side wall of the limiting plate. The other end passes through the fixed post and is located inside the fixed post. A second spring is also sleeved on the surface of the connecting rod. One end of the second spring is connected to the side wall of the limiting plate, and the other end is connected to the side wall of the fixed post.

[0012] Optionally, a first spring is connected between the lower pressure plate and the fixed box, with one end of the first spring fixedly connected to the bottom end of the lower pressure plate and the other end fixedly connected to the top end of the fixed box.

[0013] Optionally, a protective sleeve is fitted onto the surface of the outer shell, and a connecting rope is connected to the side wall of the outer shell.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up a control structure consisting of a fixed box, a lower pressure plate, a connecting column, a lower pressure block, and an adjustment component, the speed of tape measure retraction can be controlled without continuous pressing. This solves the problem of needing to continuously press the pressing block when retracting the tape measure in the existing technology, and avoids hand fatigue caused by prolonged pressing when operating with one hand.

[0016] 2. By setting the toothed groove of the limit plate in the adjustment component and the toothed engagement structure of the lower pressure block, combined with the elastic force of the second spring, a stable fixing effect on the lower pressure block is achieved, ensuring that the lower pressure block can continuously resist the tape measure and generate friction, thus ensuring the stability of the tape measure retraction speed control. Even when the tape measure is frequently retracted, efficient operation can be maintained, solving the problem of efficiency being affected by frequent operation.

[0017] 3. By setting the sliding groove, slider, and sliding plate structure on the side wall of the fixed box, the effect of conveniently releasing the pressure block is achieved. The operator can easily move the sliding plate to release the limit plate from the pressure block. The operation is simple and quick, which further improves the work efficiency when retrieving the tape measure multiple times and reduces the operator's burden. At the same time, the first spring realizes the automatic reset effect of the pressure plate. After the pressure block is released, the pressure plate can quickly return to the initial state, preparing for the next operation. This reduces the number of operation steps, improves the efficiency of continuous operation, and avoids the time wasted due to manual reset.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Example 1

[0031] Please see Figure 1-6 As shown, this embodiment provides a construction engineering measurement device, including a housing 1, with a strip-shaped hole 4 on the side wall of the housing 1, a measuring tape 5 connected inside the housing 1, and the output end of the measuring tape 5 passing through the strip-shaped hole 4; a fixing box 6 is connected to the top of the strip-shaped hole 4, a lower pressure plate 7 is provided at the top of the fixing box 6, a connecting post 10 is connected to the bottom of the lower pressure plate 7, the connecting post 10 passes through the top of the fixing box 6, and a lower pressure block 11 is connected to the other end, the bottom end of the lower pressure block 11 passes through the top of the strip-shaped hole 4 and can abut against the measuring tape 5; adjustment components are also connected to the left and right sides inside the fixing box 6, and the lower pressure block 11 is fixed by the adjustment components.

[0032] During the retraction of the measuring tape 5, there is no need for the operator to continuously press down. By adjusting the component to fix the lower pressure block 11, the lower pressure block 11 can stably resist the measuring tape 5. The friction between the two can effectively control the retraction speed of the measuring tape 5, which greatly reduces the hand fatigue of the measuring personnel when operating with one hand. On the other hand, this design helps to improve the work efficiency when retracting the measuring tape 5 frequently, thereby promoting the efficient development of construction projects and providing a strong guarantee for the smooth progress of the project.

[0033] Example 2

[0034] Please see Figure 1-6 As shown, in this embodiment, the adjustment component includes a connecting plate 14 that abuts against the inner walls of the left and right sides of the fixed box 6. A slider 12 is connected to one side of the connecting plate 14 that abuts against the inner wall of the fixed box 6, and a limiting plate 13 is connected to the other side through the connecting component. The limiting plate 13 abuts against the side wall of the lower pressing block 11, and the side wall of the limiting plate 13 is provided with a toothed groove, and the side wall of the lower pressing block 11 is provided with teeth corresponding to the toothed groove.

[0035] The toothed groove and toothed groove design can form a stable engagement when the limiting plate 13 contacts the lower pressure block 11, thereby effectively limiting the position of the lower pressure block 11. At the same time, the toothed groove and toothed groove can be used to easily adjust the friction between the lower pressure block 11 and the measuring tape 5.

[0036] The left and right side walls of the fixed box 6 are provided with slide grooves 15 corresponding to the slider 12. The slider 12 is located in the slide grooves 15, and the side wall of the slider 12 is connected to the sliding plate 8.

[0037] Example 3

[0038] Please see Figure 1-6As shown, in this embodiment, during use, the connecting plate 14 can slide in the slide groove 15 via the slider 12. The setting of the sliding plate 8 facilitates the operator to manually control the movement of the connecting plate 14. When the pressure block 11 is not needed to fix the measuring tape 5, the sliding plate 8 is moved. The sliding plate 8 drives the connecting plate 14 to move via the slider 12. The connecting plate 14 drives the limiting plate 13 to move via the connecting assembly. At this time, the toothed groove on the side wall of the limiting plate 13 slides along the teeth on the side wall of the pressure block 11, causing the toothed groove to disengage from the teeth, thereby the pressure block 11 loses its restriction, and the measuring tape 5 loses the restriction of the pressure block 11.

[0039] The connecting assembly includes a fixed post 16 and a connecting rod 17. One end of the fixed post 16 is fixedly connected to the side wall of the connecting plate 14, and one end of the connecting rod 17 is fixedly connected to the side wall of the limiting plate 13. The other end passes through the fixed post 16 and is located inside the fixed post 16. A second spring 18 is also sleeved on the surface of the connecting rod 17. One end of the second spring 18 is connected to the side wall of the limiting plate 13, and the other end is connected to the side wall of the fixed post 16.

[0040] The connecting rod 17 and the fixed column 16 can enhance the stability between the limiting plate 13 and the connecting plate 14. At the same time, when the lower pressing block 11 moves downward, due to the restriction between the groove and the teeth, the lower pressing block 11 will squeeze the limiting plate 13, and the first spring 9 will be compressed. After being released, the elastic force of the first spring 9 can drive the lower pressing plate 7 to automatically reset, which is convenient for the next operation.

[0041] A first spring 9 is connected between the lower pressure plate 7 and the fixed box 6. One end of the first spring 9 is fixedly connected to the bottom end of the lower pressure plate 7, and the other end is fixedly connected to the top end of the fixed box 6. A protective sleeve 2 is fitted on the surface of the outer shell 1, and a connecting rope 3 is connected to the side wall of the outer shell 1.

[0042] The protective sleeve 2 provides excellent protection for the outer casing 1, reducing damage caused by collisions and friction during construction and extending the service life of the measuring device. A connecting rope 3 is attached to the side wall of the outer casing 1, allowing operators to easily carry the measuring device and prevent loss due to negligence at the construction site. It also facilitates easy access and improves work convenience.

[0043] Working principle:

[0044] During the retraction of the measuring tape 5, when it is necessary to control the retraction speed of the measuring tape 5, the operator presses down the lower pressure plate 7. The lower pressure plate 7 drives the connecting column 10 to move downward. The connecting column 10 then pushes the lower pressure block 11 through the top of the strip hole 4 and abuts against the measuring tape 5. At this time, due to the downward movement of the lower pressure block 11, the teeth on its side wall will contact the tooth groove on the side wall of the limiting plate 13. Under the elastic force of the second spring 18, the limiting plate 13 always tends to move closer to the middle, so that the tooth groove and teeth are stably engaged. The lower pressure block 11 is fixed by adjusting the component. In this way, the lower pressure block 11 can continuously abut against the measuring tape 5, and the retraction speed of the measuring tape 5 can be effectively controlled by the friction between the two.

[0045] When the pressure block 11 is not needed to fix the measuring tape 5, the operator manually moves the sliding plate 8. The sliding plate 8 drives the slider 12 to slide in the slide groove 15, which in turn causes the connecting plate 14 to move. The connecting plate 14 drives the limiting plate 13 to move through the fixing post 16 and the connecting rod 17 in the connecting assembly. At this time, the toothed groove on the side wall of the limiting plate 13 slides along the toothed groove on the side wall of the pressure block 11. The toothed groove disengages from the toothed groove, and the pressure block 11 loses its restriction. At the same time, the first spring 9 between the pressure plate 7 and the fixing box 6 is compressed in the pressed state. When the pressure block 11 loses its restriction, the elastic force of the first spring 9 will drive the pressure plate 7 to automatically reset, preparing for the next operation.
