Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and in particular to a foldable and portable measuring device for architectural design. Background Technology

[0002] As is well known, architectural design measuring devices are professional tools used in the architectural design process to accurately acquire spatial data, topographic information, and object dimensions. They can measure and record key parameters such as plane coordinates, elevation, slope, and distance of the building site through laser, optical, and electronic technologies, providing basic data support for the formulation of design schemes. This ensures that the building layout, structural dimensions, and spatial relationships conform to the actual site conditions and design specifications. At the same time, they play an important role in site surveys before construction, design scheme verification, and subsequent construction layout, and are important technical equipment to ensure the scientificity, accuracy, and feasibility of architectural design.

[0003] However, traditional architectural design measuring devices are usually supported by fixed structures that cannot be folded and stored, making them difficult to transport. Therefore, there is an urgent need for technological improvements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable and portable architectural design measuring device. When in use, this device utilizes a screw, threaded sleeve, and hinged rod in conjunction with the drive and driven gears. Simply rotating a knob allows the support rod to be simultaneously unfolded and folded, improving portability. Furthermore, the screw ring, rotating ring, and locking block on the rotating rod, along with their locking grooves, securely lock the support rod in its unfolded or folded state, preventing loosening during transport or use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A foldable and portable architectural design measuring device includes a support rod. A storage slot is formed at the lower end of the outer wall of the support rod. A screw is rotatably connected to the middle of the bottom and top surfaces of the storage slot. A threaded sleeve is threaded to the lower end of the screw. A hinged rod is hinged to the outer wall of each threaded sleeve. A support rod is hinged to the lower end of each hinged rod. A driven gear is fixedly connected to the upper end of the outer wall of the screw. A rotating rod is rotatably connected to the front end of the support rod near the driven gear. A driving gear is fixedly connected to the rear end of the outer wall of the rotating rod.

[0007] The outer wall of the rotating rod is provided with an external thread, and a threaded ring is threaded to the outer wall of the external thread. A rotating ring is rotatably connected to the inner wall of the threaded ring, and multiple snap-fit ​​blocks are fixedly connected to the outer wall of the rear end of the rotating ring.

[0008] Compared with existing architectural design measuring devices, this architectural design measuring device, through the cooperation of the screw, threaded sleeve and hinge rod, and the transmission of the driving gear and driven gear, allows the support rod to be opened and closed synchronously simply by turning the knob, improving portability. The screw ring, rotating ring and locking block on the rotating rod, along with the locking groove, can securely lock the support rod in its opened or folded state, preventing loosening during carrying or use.

[0009] Furthermore, a rangefinder is fixedly connected to the upper end of the support rod;

[0010] The above technical solution facilitates distance measurement using a rangefinder.

[0011] Furthermore, the upper end of the outer wall of each support rod is rotatably connected to the upper end of the outer wall of the adjacent side of each of the multiple support rods;

[0012] The above technical solution provides a stable fulcrum for the unfolding and folding of the support rod by rotatably connecting the upper end of the outer wall of the support rod to the upper ends of multiple support rods, ensuring that the support rod can fit tightly against the support rod when stored.

[0013] Furthermore, the driving gear and the driven gear mesh with each other;

[0014] The above technical solution allows the drive gear and driven gear to mesh with each other, facilitating the rotation of the screw by the rotating rod.

[0015] Furthermore, a knob is fixedly connected to the front end of the rotating rod;

[0016] The above technical solution allows the knob to easily drive the rotating rod to rotate.

[0017] Furthermore, the upper part of the outer wall of the front end of the support rod is provided with multiple snap-fit ​​grooves, and the snap-fit ​​blocks are snap-fitted into the snap-fit ​​grooves respectively;

[0018] With the above technical solution, the snap-fit ​​blocks are snapped into the snap-fit ​​slots, which makes it easy to lock the screw and prevent external force from causing it to rotate.

[0019] Furthermore, each of the support rods is fixedly connected to an anti-slip pad, which is made of rubber and has anti-slip texture on its bottom surface.

[0020] The above technical solution effectively prevents the device from sliding due to smooth ground or slight collisions during measurement by using anti-slip pads, thus ensuring the stability of the rangefinder.

[0021] This utility model has the following beneficial effects:

[0032] Reference Figure 1-6 An embodiment of this utility model provides a foldable and portable architectural design measuring device, including a support rod 1. A storage groove 2 is provided at the lower end of the outer wall of the support rod 1. A screw 21 is rotatably connected to the middle of the bottom and top surfaces of the storage groove 2. A threaded sleeve block 22 is threadedly connected to the lower end of the screw 21. A hinge rod 23 is hinged to the outer wall of the threaded sleeve block 22. A support rod 12 is hinged to the lower end of the hinge rod 23. A driven gear 24 is fixedly connected to the upper end of the outer wall of the screw 21. A rotating rod 25 is rotatably connected to the front end of the support rod 1 near the driven gear 24. A driving gear 26 is fixedly connected to the rear end of the outer wall of the rotating rod 25.

[0033] The outer wall of the rotating rod 25 is provided with an external thread 31, and a threaded ring 32 is threadedly connected to the outer wall of the external thread 31. A rotating ring 33 is rotatably connected to the inner wall of the threaded ring 32, and multiple snap-fit ​​blocks 34 are fixedly connected to the outer wall of the rear end of the rotating ring 33.

[0034] Compared with existing architectural design measuring devices, this architectural design measuring device, through the cooperation of screw 21, threaded sleeve 22 and hinge rod 23, and the transmission of drive gear 26 and driven gear 24, only requires turning knob 27 to realize the synchronous unfolding and folding of support rod 12, improving portability. With the cooperation of screw ring 32, rotating ring 33 and locking block 34 on rotating rod 25 and locking groove 3, the unfolded or folded state of support rod 12 can be firmly locked to prevent loosening during carrying or use.

[0035] A rangefinder 11 is fixedly connected to the upper end of the support rod 1;

[0036] Distance measurement is facilitated by the rangefinder 11.

[0037] The upper end of the outer wall of the support rod 1 is rotatably connected to the upper end of the outer wall of the adjacent side of the multiple support rods 12;

[0038] The upper end of the outer wall of the support rod 1 is rotatably connected to the upper ends of multiple support rods 12, providing a stable fulcrum for the unfolding and folding of the support rod 12, ensuring that the support rod 12 can fit tightly against the support rod 1 when stored.

[0039] The driving gear 26 and the driven gear 24 mesh with each other;

[0040] The drive gear 26 and the driven gear 24 mesh with each other, which facilitates the rotation of the rotating rod 25 to drive the screw 21 to rotate.

[0041] A knob 27 is fixedly connected to the front end of the rotating rod 25;

[0042] The knob 27 facilitates the rotation of the rotating rod 25.

[0043] Multiple snap-fit ​​grooves 3 are provided on the upper part of the outer wall of the front end of the support rod 1, and the snap-fit ​​blocks 34 are snap-fitted into the snap-fit ​​grooves 3 respectively.

[0044] Each of the snap-fit ​​blocks 34 is snapped into the snap-fit ​​groove 3, which facilitates locking the screw 21 to prevent external force from causing it to rotate.

[0045] The lower end of each support rod 12 is fixedly connected with an anti-slip pad, which is made of rubber and has anti-slip texture on its bottom surface.

[0046] The anti-slip pad effectively prevents the device from sliding during measurement due to smooth ground or slight collisions, ensuring the stability of the rangefinder 11.

[0047] Working principle: When in use, rotating the knob 27 drives the rotating rod 25 to rotate. Through the meshing transmission of the driving gear 26 and the driven gear 24, the screw 21 rotates synchronously. The threaded sleeve 22 moves up and down along the screw 21, and then pushes and pulls the support rod 12 with the rotation connection point between the support rod 1 and the support rod 12 as the axis to unfold or fold, thereby realizing the adjustment of the support structure. At the same time, in conjunction with rotating the screw ring 32, the screw ring 32 moves along its external thread 31, driving the rotating ring 33 to make the locking block 34 engage with the corresponding locking groove 3, locking the position of the rotating rod 25 to fix the state of the support rod 12.
