Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a portable and retractable laser rangefinder. Background Technology

[0002] Widely used in fields such as architecture, engineering, and interior design, laser rangefinders are instruments that use lasers to accurately measure the distance to a target. They are widely used due to their high accuracy and ease of operation.

[0003] A search revealed Chinese Patent Publication No. CN222599828U, which discloses a portable laser rangefinder, belonging to the field of laser rangefinder technology. This portable laser rangefinder includes: a mounting box for mounting the laser rangefinder body; the laser rangefinder body, fixedly connected to the mounting box, for detecting the distance to objects; a fixing groove within the mounting box for housing support legs; two limiting strips fixedly connected to the fixing groove for limiting the support legs; two square slots within the fixing groove for installing second suction plates; and two second suction plates, respectively fixedly connected to the two square slots, which attract each other through mutual attraction. The attached design allows for the fixed installation of the support legs and the mounting box. When using the laser rangefinder, the two support legs are swung apart to open them, and the support rod is moved so that the mounting box can support the laser rangefinder. Then, the support plate is moved to support the support legs. This reduces carrying space and increases the convenience for workers. However, the above method uses support legs and limiting strips for storage, which does not allow for quick storage and protection using upper and lower magnetic blocks. This reduces portability, hinders quick storage and retrieval, and lowers work efficiency. Therefore, a portable and retractable laser rangefinder is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable and retractable laser rangefinder, aiming to improve the problem that some existing devices cannot be quickly and easily stored away for protection during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable and retractable laser rangefinder, comprising a laser emitter and a support plate, wherein a storage mechanism is fixedly connected to the bottom of the laser emitter, a fixing mechanism is fixedly connected inside the storage mechanism, a measuring device is fixedly connected to the outer right side of the support plate, the storage mechanism comprises a lower housing and a second storage slot, a hinge is fixedly connected to the outer left side of the lower housing, an upper housing is fixedly connected to the top of the hinge, a lower magnetic block is detachably connected to the outer right side of the lower housing, an upper magnetic block is detachably connected to the top of the lower housing, a first storage slot is provided inside the storage mechanism, a protective component is fixedly connected inside the first storage slot, a quick-release component is detachably connected inside the lower magnetic block, the protective component comprises multiple first sponge boards, the external parts of the multiple first sponge boards are fixedly connected to the perimeter of the first storage slot, and multiple second sponge boards are fixedly connected inside the second storage slot.

[0006] The above technical solution utilizes a storage mechanism that employs a hinge between the lower and upper shells to achieve foldable storage. Simultaneously, the lower and upper magnetic blocks attract each other, further enhancing stability during storage and facilitating portability. The first and second storage slots within the mechanism are respectively equipped with a first and a second sponge plate, providing excellent protection for components such as the laser emitter and reducing the risk of damage from collisions during storage and transport. Furthermore, the quick-release assembly facilitates rapid installation and removal of the laser emitter, improving efficiency.

[0007] As a further description of the above technical solution:

[0008] The quick-release assembly includes two first bolts, the external threads of which are connected to the interior of the lower magnetic block. A support connecting plate is slidably connected to the top of the upper housing. Two second bolts are internally threaded onto the support connecting plate. A second storage groove is provided inside the lower housing.

[0009] The above technical solution achieves a stable connection between the laser emitter and the storage mechanism by connecting the two first bolts to the lower magnetic block, while also facilitating quick disassembly and installation. The support connecting plate at the top of the upper housing is connected to the lower housing by two second bolts, further enhancing the overall structural stability of the storage mechanism. In addition, the second storage slot inside the lower housing provides additional storage space for related components, making the storage of the entire laser rangefinder more organized.

[0010] As a further description of the above technical solution:

[0011] The bottom threads of the two second bolts are connected to the inside of the upper housing, the left threads of the two first bolts are connected to the inside of the lower housing, the right side of the upper magnetic block is slidably connected to the top of the lower magnetic block, and a third storage groove is provided inside the lower housing.

[0012] Through the above technical solution, a stable assembly of the upper and lower shells is achieved. The sliding of the right side of the upper magnetic block and the top of the lower magnetic block allows the upper and lower shells to be quickly fixed and disassembled. The third storage slot opened in the lower shell provides storage space for related components. The overall structure not only ensures the stability of the connection and the flexibility of movement, but also optimizes the internal space layout and improves the practicality and functionality of the device.

[0013] As a further description of the above technical solution:

[0014] The fixing mechanism includes multiple elastic fastening bands, with both sides of the multiple elastic fastening bands slidably connected to the inner side of the third storage groove. Each elastic fastening band has a connecting sliding post fixedly connected to both sides of its interior, and a limit component is fixedly connected to both sides of the connecting sliding post.

[0015] The above technical solution utilizes multiple elastic fastening straps to flexibly secure accessories and tools of different shapes and sizes, ensuring their stable placement within the third storage compartment and preventing shaking and displacement during carrying and transportation.

[0016] As a further description of the above technical solution:

[0017] The limiting component includes a limiting sliding ball, which is fixedly connected to the outside of the connecting sliding column. Two limiting grooves are formed inside the lower housing, and the limiting sliding ball is slidably connected inside the limiting grooves.

[0018] The above technical solution allows the limiting sliding ball to slide in two limiting grooves opened in the lower housing, which can effectively limit and guide the movement of the connecting sliding column, ensuring the accuracy and stability of its movement path, thereby improving the operational accuracy and reliability of the entire device and ensuring the coordinated operation of the various components of the device.

[0019] As a further description of the above technical solution:

[0020] The top of the laser emitter is slidably connected to the right side of the upper housing, and the right side of the measuring device is slidably connected to the inside of the first storage slot.

[0021] Through the above technical solution: First, the sliding connection between the laser emitter and the upper housing facilitates its quick installation and disassembly, improving the convenience of use. Second, the sliding connection between the measuring device and the first storage slot allows it to fit tightly when stored, effectively reducing space occupation, and can also be quickly taken out when in use, further improving the overall portability and operational efficiency of the laser rangefinder.

[0022] As a further description of the above technical solution:

[0023] The support plate is externally fixedly connected to the inside of the upper housing, and the right side of the support plate is slidably connected to the top of the lower housing.

[0024] The above technical solution provides a stable support structure for the laser rangefinder, enhancing the overall stability of the device. The sliding connection between the support plate and the lower shell allows the support plate to be flexibly adjusted during storage and use.

[0025] As a further description of the above technical solution:

[0026] The external parts of the plurality of connecting sliding columns are slidably connected to the interior of the lower housing, and the right side of the upper housing is slidably connected to the top of the lower housing.

[0027] The above technical solution enables the connecting sliding column to slide flexibly inside the lower housing. At the same time, the sliding connection between the right side of the upper housing and the top of the lower housing further enhances the flexibility and adjustability of the overall device, making it easy to adjust the position according to actual needs and improving the adaptability and ease of use of the device.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by opening the upper and lower magnetic blocks, the upper shell can be flipped to be parallel to the lower shell, allowing the laser emitter and measuring device to work.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figures 1 to 3This utility model provides an embodiment of a portable and retractable laser rangefinder, including a laser emitter 1 and a support plate 5. A storage mechanism 3 is fixedly connected to the bottom of the laser emitter 1. The laser emitter 1 is one of the core components of the rangefinder, and its main function is to emit a laser beam. The emitted laser beam illuminates the target object, and the distance is accurately measured based on information such as the time it takes for the laser to reflect back, combined with information from the measuring device 2. The storage mechanism 3 includes a lower housing 31 and a second storage slot 36. The main function of the storage mechanism 3 is to provide a safe and compact storage space for components such as the laser emitter 1 and the measuring device 2, facilitating carrying and transportation. A hinge 38 is fixedly connected to the outer left side of the lower housing 31, and an upper housing 32 is fixedly connected to the top of the hinge 38. The lower housing 31 and the upper housing 32 are connected by the hinge 38. A lower magnetic block 34 is detachably connected to the outer right side of the lower housing 31. When it is necessary to close the storage slot, a magnetic block 34 is provided. When the storage mechanism 3 is in place, the upper housing 32 is closed, and the upper magnetic block 33 and the lower magnetic block 34 attract each other, thereby firmly fixing the upper housing 32 and the lower housing 31 together, ensuring that the internal components will not easily shake or fall off. The upper magnetic block 33 is detachably connected to the top of the lower housing 31. The storage mechanism 3 has a first storage groove 35 inside, and a protective component 39 is fixedly connected inside the first storage groove 35. The protective component 39 includes multiple first sponge plates 391. The external parts of the multiple first sponge plates 391 are fixedly connected to the perimeter of the first storage groove 35. When the measuring device 2 is stored in the first storage groove 35, the first sponge plates 391 can play a buffering and protective role, preventing the measuring device 2 from colliding with the inner wall of the storage groove and being damaged during storage. Multiple second sponge plates 392 are fixedly connected inside the second storage groove 36, and a quick-release component 37 is detachably connected inside the lower magnetic block 34.

[0040] Specifically, when the ranging function is needed, the user first separates the upper housing 32 and the lower housing 31 via the hinge 38, thereby separating the upper magnetic block 33 and the lower magnetic block 34. After unfolding the storage mechanism 3, the measuring device 2, which is protected by the first sponge plate 391, is taken out from the first storage slot 35. At the same time, the laser emitter 1, protected by the second sponge plate 392, is taken out from the second storage slot 36. The laser emitter 1 is installed on the support plate 5 and the device is started. At this time, the laser beam emitted by the laser emitter 1 illuminates the target object, and the reflected signal is received by the measuring device 2 to calculate the distance data. After use, the laser emitter 1 and the measuring device 2 are put back into the second storage slot 36 and the first storage slot 35 respectively. The cushioning characteristics of the sponge plate are used to prevent collision damage. Finally, the upper housing 32 is flipped by the hinge 38 to make the magnetic block adsorb and close, completing the storage.

[0041] The quick-release assembly 37 includes two first bolts 371, the external threads of which are connected to the interior of the lower magnetic block 34. The top of the upper housing 32 is slidably connected to a support connecting plate 373, and the internal threads of the support connecting plate 373 are connected to two second bolts 372. The first bolts 371 and the second bolts 372 facilitate the quick replacement and maintenance of the upper magnetic block 33 and the lower magnetic block 34. The interior of the lower housing 31 has a second storage slot 36, and the interior of the storage mechanism 3 is fixedly connected to a fixing mechanism 4. The right side of the support plate 5 is fixedly connected to a measuring device 2, which is responsible for receiving the laser signal emitted by the laser emitter 1 and reflected back from the target object, and calculating the distance between the target object and the rangefinder. The bottom threads of the two second bolts 372 are connected to the interior of the upper housing 32, and the left threads of the two first bolts 371 are connected to the interior of the lower housing 31. The right side of the upper magnetic block 33 is slidably connected to the top of the lower magnetic block 34. The interior of the lower housing 31 has a third storage slot 6, which can be used to fix tools and other items during use.

[0042] Specifically, when the ranging function is needed, the user first loosens the first bolt 371 and the second bolt 372 in the quick-release assembly 37 to release the fixation between the upper magnetic block 33 and the lower magnetic block 34. Then, the user flips the upper housing 32 to open the storage mechanism 3, takes out the measuring device 2 from the first storage slot 35, takes out the laser emitter 1 from the second storage slot 36, and installs it on the support plate 5. After starting the device, the laser emitter 1 emits a laser beam to the target object, and the reflected signal is received by the measuring device 2 to calculate the distance. After use, the laser emitter 1 and the measuring device 2 are put back into the second storage slot 36 and the first storage slot 35, respectively, and the first sponge plate 391 and the second sponge plate 392 provide cushioning protection. If other tools and items need to be stored, they can be placed in the third storage slot 6.

[0043] Reference Figure 1 , Figure 4 and Figure 5The fixing mechanism 4 includes multiple elastic fastening bands 41. Each elastic fastening band 41 has a certain elasticity and can stretch and contract appropriately according to the size and shape of the storage component, thereby tightly wrapping the component and providing a fixing function. The two sides of the multiple elastic fastening bands 41 are slidably connected to the inner side of the third storage groove 6. Each elastic fastening band 41 has a connecting sliding post 42 fixedly connected to its inner two sides. The connecting sliding post 42 slides within the third storage groove 6, allowing the elastic fastening band 41 to flexibly adjust its position to adapt to different storage needs. Limiting components 43 are fixedly connected to both sides of the connecting sliding post 42. The limiting components 43 include limiting sliding balls 431, the inner side of which is fixedly connected to the outer side of the connecting sliding post 42. Two limiting grooves 432 are opened inside the lower housing 31, and the limiting sliding balls 431 are slidably connected inside the limiting grooves 432, limiting the sliding range of the connecting sliding post 42. To prevent the elastic fastening band 41 from sliding excessively and detaching from the third storage slot 6, thereby ensuring the stability and reliability of the fixing mechanism 4, the top of the laser emitter 1 is slidably connected to the right side of the upper housing 32, the right side of the measuring device 2 is slidably connected to the inside of the first storage slot 35, the outside of the support plate 5 is fixedly connected to the inside of the upper housing 32, and the right side of the support plate 5 is slidably connected to the top of the lower housing 31. The support plate 5 mainly plays the role of support and connection. On the one hand, the support plate 5 provides a stable installation platform for the measuring device 2, ensuring the stability of the measuring device 2 during operation. On the other hand, through the connection with the upper housing 32 and the lower housing 31, the laser emitter 1, the measuring device 2 and other components are connected to the storage mechanism 3 as a whole, improving the structural strength and stability of the entire rangefinder. The outside of the multiple connecting sliding columns 42 is slidably connected to the inside of the lower housing 31, and the right side of the upper housing 32 is slidably connected to the top of the lower housing 31.

[0044] Specifically, the laser emitter 1 is positioned by sliding its top to the right side of the upper housing 32. At the same time, the right side of the measuring device 2 slides along the first storage groove 35 to adjust its working position. The fixing mechanism 4 adapts to the shape of different components through the elastic deformation of multiple elastic fastening bands 41. Its two sides slide in the third storage groove 6 through the connecting sliding columns 42, driving the limiting sliding ball 431 of the limiting component 43 to move along the limiting groove 432 of the lower housing 31, ensuring both sliding flexibility and preventing detachment. The support plate 5 is fixed inside the upper housing 32 and slides to the top of the lower housing 31 on its right side, providing stable support for the measuring device 2 and enhancing the overall structural rigidity. The upper housing 32 and the lower housing 31 open and close through top sliding cooperation. All components work together under the constraint of the limiting groove 432 and the connecting sliding column 42 to complete the functions of measurement and fixing.

[0045] Working principle: First, during use, the upper magnetic block 33 and the lower magnetic block 34 are opened, allowing the upper housing 32 to flip and become parallel to the lower housing 31. At this point, the laser emitter 1 and the measuring device 2 are in operation. When not in use, they are stored away. During storage, the upper housing 32 flips back to fit against the lower housing 31, allowing the laser emitter 1 and the measuring device 2 to be stored in the first storage slot 35 and the second storage slot 36. The lower magnetic block 34 and the first storage slot 35 attract each other, quickly fixing the lower housing 31 and the upper housing 32. Simultaneously, the supporting connecting plate 373 and the lower magnetic block 34 are quickly installed using the first bolt 371 and the second bolt 372. During storage, the first sponge plate 391 and the second sponge plate 392 provide protection, preventing damage and extending the device's lifespan. This improves the portability of the laser rangefinder, making it easy to carry and use, achieving quick storage and retrieval, and increasing work efficiency.

[0046] Furthermore, the lower housing 31 has a third storage slot 6 inside, where items and tools can be placed. The connecting sliding column 42 slides inside the lower housing 31, and during this sliding, the elastic fastening band 41 slides inside the third storage slot 6. The limiting sliding ball 431 slides inside the limiting groove 432, thus limiting the placement of items and tools. This prevents items from being piled up haphazardly, improves space utilization, and also secures the internal items, increasing the stability of the device.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
