Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a building engineering construction measuring rod. Background Art

[0002] The measuring rod is a measuring device used in conjunction with a level during construction. When performing vertical measurements, the measuring rod is usually placed vertically on the object to be measured or on the ground. The height can be directly read by observing the scale to ensure that the foundation and other structures of the building are constructed according to the designed elevation. When the measuring rod is not in use, the measuring rod is usually put into a bag for storage. However, when this storage method encounters impact or collision, the soft bag cannot protect the measuring rod. In addition, existing measuring rods are hollow for easy carrying. When the measuring rod is hit, it is easy to deform and bend, resulting in the measuring rod being unable to continue to be used and causing losses. In addition, when the measuring rod is in use, the random placement of the bag can easily cause dust or stones to accumulate inside, resulting in the measuring rod being easily worn and losing accuracy during storage.

[0003] At the same time, since the measuring rods used in construction projects are all used outdoors, when encountering strong sunlight, the side of the measuring rod with the scale lines is set to a smooth plane for easy observation of the scales. The smooth plane is prone to reflection when encountering sunlight, which in turn interferes with the workers' reading of the scale lines on the plane, causing reading deviations or errors. Summary of the invention

[0004] In order to overcome the shortcomings that the existing bags for storing measuring rods cannot protect the measuring rods when they are hit, and dust or stones are easily accumulated inside the randomly placed bags, causing the measuring rods to be worn, and at the same time, the smooth surface is prone to reflection under strong sunlight, affecting the workers' reading of the scale, the present invention provides a construction engineering construction measuring rod.

[0005] The technical solution is as follows: a construction engineering measurement rod, including a telescopic rod and a bottom rod; the telescopic rod is slidably connected to the upper side of the bottom rod; the telescopic rod and the bottom rod are both arranged to be hollow; scale lines are arranged on the telescopic rod and the bottom rod; it also includes a protective cover, a baffle and a storage assembly; a protective cover is arranged on the outer side of the bottom rod to prevent the telescopic rod and the bottom rod from being compressed and deformed; the front and rear sides of the protective cover are longer than the front and rear sides of the bottom rod; a baffle is slidably connected inside the protective cover to prevent reflection caused by direct sunlight; the baffle is connected to the telescopic rod; the front side of the protective cover is connected to a storage assembly to prevent the scale lines from being worn.

[0006] Furthermore, the storage assembly includes a plug plate, an elastic band and a locking block; two elastic bands are fixedly connected to the inside of the front side of the protective cover; a plug plate is fixedly connected to the front side of each elastic band to prevent the scale line from being worn; and several locking blocks are slidably connected to the upper and lower front sides of the protective cover.

[0007] Furthermore, the middle parts of the front sides of the telescopic rod and the bottom rod are both arranged to be concave, and the scale lines are all located at the concave parts.

[0008] Furthermore, a first scattering portion for reducing sunlight reflection is arranged at the recessed portion of the telescopic rod; a second scattering portion is arranged at the recessed portion of the bottom rod; and both the first scattering portion and the second scattering portion are arranged in a concave arc shape.

[0009] Furthermore, the two plug plates fit in the recessed areas on the front side of the bottom rod.

[0010] Furthermore, each elastic band is composed of a plurality of bands.

[0011] Furthermore, it also includes an airbag, a base and an air pipe; the left and right sides of the protective cover are provided with grooves for workers to grasp, and anti-slip strips are provided in the grooves; an airbag for dust cleaning is fixedly connected to the lower side of the protective cover; the lower side of the airbag is fixedly connected to the base; the base and the lower side of the protective cover are plugged into each other; the left and right sides of the airbag are connected to the air pipe; a first unidirectional membrane is fixed in the air pipe; and a filter is provided at each end of the air pipe.

[0012] Furthermore, it also includes a second one-way membrane; a plurality of first circular holes are opened on the telescopic rod; a plurality of second circular holes are opened on the bottom rod; each of the first circular hole and the second circular hole is fixed with a second one-way membrane for facilitating cleaning of dust on the scale lines of the telescopic rod and the bottom rod; each second one-way membrane opens toward the middle of the telescopic rod and the bottom rod.

[0013] Furthermore, a clamping portion is provided on the rear side of the protective cover to reduce the friction between the telescopic rod and the bottom rod during stacking and transportation; and a fitting portion is provided on the front side of the protective cover.

[0014] Furthermore, the clamping portion and the engaging portion are both configured to be arc-shaped.

[0015] The beneficial effects are as follows: the present invention realizes that the outer surface of the bottom rod is wrapped by the protective cover, and the force applied to the telescopic rod and the bottom rod is buffered by the protective cover, thereby protecting the telescopic rod and the bottom rod; The front sides of the telescopic rod and the bottom rod are both set to be concave, and the scale lines are located in the concave places, so that it is difficult for sunlight to shine on the scale lines in the concave places of the telescopic rod and the bottom rod, thereby reducing the reflection phenomenon at the scale lines; By using the first scattering part and the second scattering part to be both concave arc-shaped, sunlight is scattered when it contacts the concave arc surface after being irradiated on the scale line, thereby reducing the reflection of workers during the inspection process; Since each elastic band is composed of multiple straps, workers can pull out a single strap or multiple straps to serve as hand straps, making it easier for workers to take the telescopic pole and the bottom pole; The gas in the airbag is compressed to flow into the telescopic rod and the bottom rod, so that the dust adhering to the scale line is blown off. At the same time, the worker drives the telescopic rod and the bottom rod up and down to cause the dust to be completely shaken off the scale line, thereby conveniently cleaning the dust on the scale line.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 like Figure 2-Figure 6 As shown, a construction engineering construction measuring rod includes a telescopic rod 1 and a bottom rod 4; the telescopic rod 1 is slidably connected to the upper side of the bottom rod 4; the telescopic rod 1 and the bottom rod 4 are both hollow; and scale lines are provided on the telescopic rod 1 and the bottom rod 4; It also includes a protective cover 2, a baffle 3 and a storage assembly; the protective cover 2 is arranged on the outside of the bottom rod 4; the front and rear sides of the protective cover 2 are longer than the front and rear sides of the bottom rod 4; the baffle 3 is slidably connected inside the protective cover 2; the baffle 3 is connected to the telescopic rod 1; and the storage assembly is connected to the front side of the protective cover 2.

[0020] The storage assembly includes a plug plate 101, an elastic band 102 and a locking block 103; two elastic bands 102 are fixedly connected to the front side of the protective cover 2; a plug plate 101 is fixedly connected to the front side of each elastic band 102; and a plurality of locking blocks 103 are slidably connected to the upper and lower front sides of the protective cover 2.

[0021] The front middle parts of the telescopic rod 1 and the bottom rod 4 are both arranged to be concave, and the scale lines are all located at the concave parts.

[0022] A first scattering portion 1001 is provided at the concave portion of the telescopic rod 1; a second scattering portion 4001 is provided at the concave portion of the bottom rod 4; both the first scattering portion 1001 and the second scattering portion 4001 are provided in a concave arc shape.

[0023] The two plug plates 101 fit in with the depressions on the front side of the bottom rod 4, and the plug plates 101 are used to block the scale lines at the position of the second scattering portion 4001 to reduce the wear on the scale lines. At the same time, they cooperate with the protective cover 2 to completely cover the telescopic rod 1 and the bottom rod 4 for protection.

[0024] Each elastic band 102 is composed of a plurality of bands.

[0025] When using the measuring rod, the worker first places the bottom rod 4 on the ground, then pulls the telescopic rod 1 out of the bottom rod 4 to a certain height, and then observes and detects the scale lines on the telescopic rod 1 and the bottom rod 4 through the instrument of another worker. When the telescopic rod 1 and the bottom rod 4 are used, the existing storage method puts the telescopic rod 1 and the bottom rod 4 into a cloth bag. This method cannot play a protective function when the telescopic rod 1 and the bottom rod 4 are squeezed, causing the telescopic rod 1 and the bottom rod 4 to be easily compressed, deformed or damaged. In order to avoid this phenomenon, a protective cover 2 is provided on the outer surface of the bottom rod 4. When the telescopic rod 1 is stored in the bottom rod 4, the protective cover 2 is used to wrap the outer surface of the bottom rod 4. Then, when the telescopic rod 1 and the bottom rod 4 are squeezed, the protective cover 2 is used to buffer the force applied to the telescopic rod 1 and the bottom rod 4, thereby protecting the telescopic rod 1 and the bottom rod 4.

[0026] It is also taken into consideration that the telescopic rod 1 and the bottom rod 4 are usually used for measurement at outdoor construction sites. When encountering strong sunlight, the front sides of the telescopic rod 1 and the bottom rod 4 are set as smooth planes for the convenience of workers to read the scale lines. When such smooth planes encounter strong sunlight, the strong sunlight is easily reflected on the planes, thereby affecting the workers' observation of the scale lines on the telescopic rod 1 and the bottom rod 4. In order to avoid this phenomenon, the front sides of the telescopic rod 1 and the bottom rod 4 are set to be concave, and the scale lines are located in the concave. When sunlight shines on the front sides of the telescopic rod 1 and the bottom rod 4, most of the sunlight is blocked by the concave structure, making it difficult for the sunlight to directly shine on the telescopic rod 1 and the bottom rod 4. The scale lines at the recessed parts of the telescopic rod 1 and the bottom rod 4 can reduce the reflection phenomenon at the scale lines, thereby reducing the impact on the workers' inspection and observation. At the same time, in the above process, considering the extreme conditions, when the sunlight is directly irradiated on the front side of the telescopic rod 1 and the bottom rod 4, the first scattering part 1001 and the second scattering part 4001 are both set to a concave arc shape. In the concave structure, the light is continuously refracted and reflected on the curved surface. Each time a part of the light is reflected, it will be absorbed or scattered at a non-vertical angle, reducing the amount of light directly reflected back into the air, so that the sunlight is scattered when it contacts the concave arc surface after being irradiated on the scale lines, thereby reducing the reflection of the workers during the inspection process.

[0027] It is also considered that, since the scale line arranged on the front side of the bottom rod 4 faces the inspector, the length of the front side and the rear side of the protective cover 2 are longer than the front side and the rear side of the bottom rod 4, so that the protective cover 2 can block the sunlight while storing the protective bottom rod 4, and the sunlight that can be irradiated to the front side of the bottom rod 4 is further reduced. Similarly, when the telescopic rod 1 is extended, the telescopic rod 1 simultaneously drives the baffle 3 to be pulled out upward, and then Figure 2 In the manner shown, the front side and the rear side of the baffle 3 are both longer than the front side and the rear side of the telescopic rod 1 , thereby further shielding the telescopic rod 1 .

[0028] It is also considered that when the telescopic rod 1 is stored in the bottom rod 4, the worker pulls out the two plug plates 101 and inserts them into the recessed area on the front side of the bottom rod 4, such as Figure 6As shown, the two plug plates 101 are embedded in the recessed part on the front side of the bottom rod 4, thereby protecting the scale lines, preventing the scale lines from contacting the outside world, reducing the loss of the scale lines, and ensuring the accuracy of the equipment. At the same time, the two plug plates 101 inserted into the recessed part on the front side of the bottom rod 4 cooperate with the protective cover 2 to completely cover the outer surface of the bottom rod 4, thereby protecting the bottom rod 4 in all aspects. At the same time, when the two plug plates 101 are inserted into the recessed part on the front side of the bottom rod 4, the two elastic bands 102 are pulled out from the protective cover 2. At this time, the worker presses the locking block 103 to move toward the plug plate 101, thereby locking the upper and lower ends of the plug plate 101. Each elastic band 102 is composed of multiple straps. After the worker pulls out the elastic band 102, he can pull out a single or multiple straps of the elastic band 102 to act as a hand strap, which is convenient for the worker to take the telescopic rod 1 and the bottom rod 4.

[0029] Example 2 On the basis of Example 1, Figure 1 , Figure 2 and Figure 7-Figure 10 As shown, it also includes an airbag 201, a base 202 and an air pipe 203; the left and right sides of the protective cover 2 are provided with grooves for workers to grasp, and anti-slip strips are provided in the grooves; the airbag 201 is fixedly connected to the lower side of the protective cover 2; the base 202 is fixedly connected to the lower side of the airbag 201; the base 202 and the lower side of the protective cover 2 are plugged into each other; the left and right sides of the airbag 201 are connected to the air pipe 203; the first unidirectional membrane 204 is fixedly connected in the air pipe 203; and a filter is provided at the end of each air pipe 203.

[0030] It also includes a second one-way membrane 205; a plurality of first circular holes 1002 are opened on the telescopic rod 1; a plurality of second circular holes 4002 are opened on the bottom rod 4; a second one-way membrane 205 is fixedly connected to each first circular hole 1002 and the second circular hole 4002; each second one-way membrane 205 opens toward the middle of the telescopic rod 1 and the bottom rod 4.

[0031] A clamping portion 2001 is provided on the rear side of the protective cover 2 ; and a fitting portion 2002 is provided on the front side of the protective cover 2 .

[0032] The clamping portion 2001 and the engaging portion 2002 are both configured in an arc shape, which is convenient for manual picking up, and the arc shape is more conducive to the clamping portion 2001 and the engaging portion 2002 being engaged with each other.

[0033] During the use of the telescopic rod 1 and the bottom rod 4, considering that they are often used in construction sites, when workers encounter dust during the inspection process, the floating dust is easy to adhere to the scale line position of the telescopic rod 1 and the bottom rod 4, and the adhesion of dust is easy to affect the workers' observation of the scale line, thereby affecting the readings. Since the heights of the telescopic rod 1 and the bottom rod 4 are higher than that of ordinary people, when dust adheres to the telescopic rod 1 and the bottom rod 4, the workers need to tilt the telescopic rod 1 and the bottom rod 4 and place them on the ground for wiping, which is extremely inconvenient. When dust occurs, the workers step on the base 202, pull the protective cover 2 upward, and then deploy the airbag 201 as shown in FIG. Figure 7 As shown, it should be noted that: in the initial state, the base 202 and the lower side of the protective cover 2 are interlocked and plugged with each other, and when the airbag 201 is not in use, the base 202 is tightly embedded in the lower side of the protective cover 2. When the airbag 201 needs to be used, the worker steps on the base 202, holds the grooves on the left and right sides of the protective cover 2, and uses the anti-slip strips in the grooves to facilitate the worker to stably hold the protective cover 2 and move it back and forth up and down, thereby driving the telescopic rod 1 and the bottom rod 4 to move back and forth up and down. Since the interior of the telescopic rod 1 and the bottom rod 4 are both hollow, and a plurality of first circular holes 1002 and second circular holes 4002 are respectively opened on the telescopic rod 1 and the bottom rod 4, when the worker holds the protective cover 2 and moves downward, the airbag 201 is squeezed, and the first unidirectional membrane 204 is closed, so that the gas in the airbag 201 flows into the interior of the telescopic rod 1 and the bottom rod 4, and then sprays out through the first circular holes 1002 and the second circular holes 4002, from The dust on the scale lines is blown off by blowing toward the telescopic rod 1 and the bottom rod 4, and the worker simultaneously shakes the telescopic rod 1 and the bottom rod 4 up and down to completely shake off the dust on the scale lines, thereby conveniently cleaning the dust on the scale lines without tilting the telescopic rod 1 and the bottom rod 4 on the ground for manual wiping. In this process, in order to further ensure the dust cleaning effect, when the gas in the airbag 201 is blown into the telescopic rod 1 and the bottom rod 4, it is blocked by the second unidirectional membrane 205 and cannot be ejected from the first circular hole 1002 and the second circular hole 4002 in the first time. When the airbag 201 continues to be compressed, the gas pressure inside the telescopic rod 1 and the bottom rod 4 gradually increases, thereby opening the second unidirectional membrane 205, so that the gas is evenly ejected from each first circular hole 1002 and the second circular hole 4002, and the dust in each area of ​​the scale lines is evenly blown away, thereby improving the cleaning effect of the scale lines.

[0034] It is also taken into consideration that when the telescopic rod 1 is stored in the bottom rod 4 for storage and transportation, most of the time when the measuring rods are stacked, soft pads or isolation materials, such as foam boards or rubber pads, are placed between each layer to reduce the extrusion of the direct contact surface. Considering the bumps and shaking during transportation, it is easy to cause relative displacement and extrusion between the two adjacent telescopic rods 1 and the bottom rod 4. In order to reduce the mutual extrusion and friction between the telescopic rods 1 and the bottom rod 4 when they are stacked, the clamping part 2001 set on the rear side of the protective cover 2 is used to clamp into the mosaic part 2002 on the other protective cover 2 when stacked, so that the two adjacent protective covers 2 are plugged into each other through the clamping part 2001 and the mosaic part 2002, which is convenient for storage and reduces the shaking and extrusion of the two adjacent telescopic rods 1 and the bottom rod 4 during transportation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
