[0002] Civil engineering surveying plays a crucial role in all stages of civil engineering construction. Surveying can determine key data such as the scope, boundaries, and area of ​​a site. For example, when building a highway, it is necessary to accurately know the land area occupied by the route in order to assess related costs such as land acquisition. It also provides necessary data support for determining the route alignment and planning the location of facilities such as service areas, helping engineers to comprehensively consider various factors and optimize engineering design schemes during the design phase.

[0003] The measuring equipment typically used outdoors often consists of large rulers. However, these rulers cannot rotate automatically, requiring continuous rotation during retrieval. This results in the ruler taking too long to retract, and the ruler may become loose, making it difficult to retract completely. Utility Model Content

[0004] This disclosure relates to a measuring device in which a support component is directly installed on the top of the measuring equipment. During measurement, the support component provides better positional accuracy. The clamping component of the measuring equipment directly presses against the linear ruler, making the linear ruler more stable when retracted. The control component provides better retraction of the linear ruler. A pulling component is installed on the opposite side of the control component, which can increase the speed of retraction of the linear ruler by pulling.

[0005] In a first aspect, this disclosure provides a measuring device, specifically comprising: a measuring apparatus; a linear ruler is wound around the inner end of the measuring apparatus, a support component is installed at the top of the measuring apparatus, a clamping component is slidably installed at the upper end of the measuring apparatus, the clamping component is in contact with the linear ruler, a control component is installed on the outer surface of the measuring apparatus, and a pulling component is added to the opposite side of the control component of the measuring apparatus.

[0006] In at least some embodiments, the outer frame of the measuring device is configured as a cross-shaped frame structure, a handheld frame is provided at the top of the outer frame, and a positioning block is installed at the bottom of the outer frame, the positioning block being tapered.

[0007] In at least some embodiments, the connecting block of the support assembly is configured to be installed on the top of the measuring device, and two sets of rotating frames are rotatably mounted on the connecting block. The rotating frames are configured as two symmetrical structures, and a support rod is provided at the end of the rotating frame. The support rod adopts a telescopic structure, the support rod of the rotating frame is configured to be inclined, and a contact head is provided at the end of the support rod.

[0008] In at least some embodiments, the sliding plate of the clamping assembly is disposed at the upper end of the measuring device, a sliding frame is slidably mounted on the sliding plate, a tension spring is installed on the sliding frame at the mounting position of the sliding plate, and clamping wheels are rotatably mounted at both ends of the sliding frame, with anti-slip structures provided on the clamping wheels.

[0009] In at least some embodiments, the control component is connected to the outside of the measuring device, a control plate is slidably mounted on the transmission block, a limit block is added at the position where the control plate is mounted on the transmission block, and a handheld block is connected and mounted at the end of the control plate.

[0010] In at least some embodiments, the drive shaft of the pulling component is mounted on the opposite side of the control component on the measuring device, an outer disc is mounted at the outer end of the drive shaft, the drive shaft adopts a one-way ratchet structure, a pull rope is wound around the outer end of the outer disc, and a coil spring is installed inside the outer disc.

[0011] This utility model provides a measuring device with the following advantages:

[0012] In this invention, a support component is directly installed at the top of the measuring device. After the measuring device pulls out the linear ruler, the support component unfolds to the ground, allowing the positioning block of the measuring device to better determine its position. A clamping component is added to the measuring device to clamp the linear ruler, ensuring that it is firmly held in place during retraction and preventing it from becoming loose. The control component is adjustable, allowing the linear ruler to be quickly retracted as it rotates. A pulling component with a one-way ratchet is installed on the opposite side of the control component, enabling the linear ruler to be driven and thus allowing the control component to retract more quickly.

[0013] In addition, the rotating frame is directly mounted on the connecting block, so that the two sets of rotating frames can be unfolded. The support rod connected to the end of the rotating frame can be unfolded to support the entire device, which facilitates the position determination of the measuring equipment. The support rod is set as a telescopic structure so that the support rod supports the entire measuring equipment after it extends. The support rod is set to be inclined at the point where the rotating frame is mounted on the support rod to achieve a stable support effect. The contact head at the end of the support rod has a stabilizing effect by increasing the support.

[0014] In addition, the sliding plate is directly set at the upper part of the measuring equipment, and a sliding frame is slidably installed on the sliding plate. A tension spring is added to the mounting point of the sliding frame to make the two sets of pressure wheels of the sliding frame press stably on the linear ruler, thereby tightening the linear ruler when it is retracted and avoiding the problem of loosening when the linear ruler is retracted.

[0015] In addition, the control plate on the transmission block is set to slide, and the spring in the limit block can push the limit block out and press it against the control plate, thereby controlling the sliding position of the control plate. The hand-held block at the end of the control plate makes it easy to control the entire control assembly.

[0016] In addition, the outer disc's pull rope is initially in a wound state. When the pull rope is manually pulled, it causes the outer disc to rotate, which in turn drives the drive shaft, thus retracting the linear ruler. When the force is released, the coil spring drives the outer disc to rotate back, causing it to retract the pull rope. The outer disc and drive shaft are connected by a one-way ratchet, which prevents the rotating ratchet from controlling the linear ruler. By repeating this process, the linear ruler can be quickly retracted. Attached Figure Description

Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1: Please refer to Figures 1 to 6 :

[0035] This utility model proposes a measuring device, including: a measuring device 1; a linear ruler 6 is wound around the inner end of the measuring device 1, a support component 2 is installed at the top of the measuring device 1, a clamping component 3 is slidably installed at the upper end of the measuring device 1, the clamping component 3 is in contact with the linear ruler 6, a control component 4 is installed on the outer side of the measuring device 1, and a pulling component 5 is added to the opposite side of the control component 4 of the measuring device 1.

[0036] In this embodiment of the disclosure, such as Figure 2 As shown, the outer frame 101 of the measuring device 1 is configured as a cross frame structure. A handheld frame 102 is provided at the top of the outer frame 101, and a positioning block 103 is installed at the bottom of the outer frame 101. The positioning block 103 is tapered, which directly sets the outer frame 101 as a cross frame structure, allowing the outer frame 101 to form a stable clamping and installation of the linear ruler 6. The handheld frame 102 at the top of the outer frame 101 makes it easy to hold and use, while the positioning block 103 at the bottom of the outer frame 101 enables convenient positioning when the measuring device 1 is in use.

[0037] In this embodiment of the disclosure, such as Figure 6As shown, the connecting block 201 of the support assembly 2 is installed on the top of the measuring device 1. Two sets of rotating frames 202 are rotatably mounted on the connecting block 201. The rotating frames 202 are arranged in two symmetrical structures. A support rod 203 is provided at the end of the rotating frame 202. By directly rotating the rotating frame 202 on the connecting block 201, the two sets of rotating frames 202 can be unfolded. Then, the support rod 203 connected to the end of the rotating frame 202 can be unfolded to support the entire device, facilitating the positioning of the measuring device 1. The support rod 203 is designed with a telescopic structure. The support rod 203 of the rotating frame 202 is set in an inclined position. The end of the support rod 203 is provided with a contact head 204. The support rod 203 is set with a telescopic structure so that after the support rod 203 is extended, it can support the entire measuring device 1. The part of the rotating frame 202 where the support rod 203 is installed is set in an inclined position so that the support rod 203 can achieve a stable supporting effect. The contact head 204 at the end of the support rod 203 has a stabilizing effect of increasing the support.

[0038] In this embodiment of the disclosure, such as Figure 5 As shown, the sliding plate 301 of the clamping assembly 3 is located at the upper end of the measuring device 1. A sliding frame 302 is slidably mounted on the sliding plate 301. A tension spring is installed on the sliding frame 302 at the mounting position of the sliding plate 301. A clamping wheel 303 is rotatably mounted at both ends of the sliding frame 302. The clamping wheel 303 is provided with an anti-slip structure. The sliding plate 301 is directly positioned at the upper end of the measuring device 1, and the sliding frame 302 is slidably mounted on the sliding plate 301. A tension spring is installed at the mounting position of the sliding frame 302, so that the two sets of clamping wheels 303 of the sliding frame 302 are stably pressed on the linear ruler 6, thereby tightening the linear ruler 6 when it is retracted and avoiding the problem of loosening when the linear ruler 6 is retracted.

[0039] In this embodiment of the disclosure, such as Figure 4 As shown, the control component 4 is connected to the outside of the measuring device 1. A control plate 402 is slidably mounted on the transmission block 401. A limit block 403 is added at the position where the control plate 402 is mounted on the transmission block 401. A hand-held block 404 is connected and mounted at the end of the control plate 402. The control plate 402 on the transmission block 401 is set to be slidably mounted. The spring in the limit block 403 can push the limit block 403 out and let the limit block 403 press against the control plate 402, so as to control the sliding position of the control plate 402. The hand-held block 404 at the end of the control plate 402 makes it convenient for the control component 4 to be controlled as a whole.

[0040] In this embodiment of the disclosure, such as Figure 3As shown, the drive shaft 501 of the pulling component 5 is installed on the opposite side of the control component 4 on the measuring device 1. An outer disc 502 is installed at the outer end of the drive shaft 501. The drive shaft 501 adopts a one-way ratchet structure. A pull rope 503 is wound around the outer end of the outer disc 502. A coil spring 504 is installed inside the outer disc 502. At first, the pull rope 503 of the outer disc 502 is in a wound state. At this time, manually pulling the pull rope 503 will cause the pull rope 503 to drive the outer disc 502 to rotate. The outer disc 502 will then drive the drive shaft 501 to achieve the function of retracting the linear ruler 6. When the force is released, the coil spring 504 will drive the outer disc 502 to rotate back, allowing the outer disc 502 to rotate and retract the pull rope 503. Since there is a one-way ratchet between the outer disc 502 and the drive shaft 501, the rotating ratchet will not control the linear ruler 6. By repeating this process, the linear ruler 6 can be retracted quickly.

[0041] The working principle of this embodiment is as follows: When in use, the linear ruler 6 of the measuring device 1 is fixed at the designated position. The holding frame 102 is held and the linear ruler 6 is pulled and extended until the measuring device 1 reaches the designated position. Then, the support component 2 of the measuring device 1 is rotated to allow the support component 2 to unfold and support the ground, thereby making the bottom positioning block 103 of the measuring device 1 vertical and forming a good positioning.

[0042] When the linear ruler 6 is retracted, the clamping component 3 of the measuring device 1 will press on the linear ruler 6. When it is not necessary to retract it quickly, the control component 4 can be slid to the designated position and the hand block 404 of the control component 4 can be unfolded to retract the linear ruler 6 through the control component 4.

[0043] When it is necessary to quickly retract the linear ruler 6, simply pull the pull rope 503, which will drive the outer disc 502 to transmit power to the linear ruler 6. The outer disc 502 and the transmission shaft 501 are equipped with a one-way ratchet, which allows the pulling component 5 to quickly retract the linear ruler 6.
