Description

Technical Field

[0001] This utility model relates to the field of housings, specifically a sealed and waterproof housing for an electronic rangefinder. Background Technology

[0002] An electronic distance measuring instrument is a precision instrument widely used in surveying, construction, exploration, and other fields. Its main function is to measure the distance between two points electronically. The working principle of an electronic distance measuring instrument is typically based on physical principles such as laser, ultrasound, or infrared, calculating distance by emitting and receiving reflected signals. These devices integrate complex electronic components and sensors to ensure the accuracy and stability of the measurement.

[0003] To ensure the proper functioning of electronic rangefinders in various harsh environments, especially considering waterproofing requirements, existing electronic rangefinders are typically equipped with housings. These housings are usually made of plastic and designed with a tight-fitting structure to minimize water intrusion. Waterproof gaskets or seals are also usually placed inside the housing for additional waterproof protection. However, despite these designs, sealing waterproof housings in existing electronic rangefinders still faces many challenges.

[0004] Existing sealed waterproof housings for electronic rangefinders have the following defects: Poor sealing performance: Existing sealed waterproof housings for electronic rangefinders typically consist of a top shell and a bottom shell. After prolonged use, due to material aging, wear, or improper installation, the sealing performance often gradually declines. This allows water to easily penetrate the housing, damaging electronic components and affecting the accuracy and stability of the rangefinder. Poor waterproofing: Although existing housings are designed with waterproof gaskets or sealing rings, in practical applications, these gaskets or sealing rings often cannot completely and effectively prevent water intrusion. After installation, the sealing ring lacks a fixing structure and grooves to limit its position. One end of the sealing ring is bonded to the top shell, and the other end is bonded to the bottom shell. Therefore, water can enter through the gaps between the two. Furthermore, the sealing ring is not securely installed: In existing sealed waterproof housings for electronic rangefinders, the sealing ring is usually directly bonded without grooves for limiting its position. Therefore, the sealing ring is often not securely installed on the housing. In addition, when subjected to external impact, the sealing ring is prone to delamination because it lacks a fixed structure and groove for limiting and fixing. This can lead to loosening or falling off during use, thereby reducing the sealing and waterproof performance of the outer casing. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a sealed and waterproof housing for electronic rangefinders, which can effectively solve the technical problems of poor housing sealing, poor waterproof performance, and unstable installation of sealing rings in existing electronic rangefinders.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a sealed and waterproof outer shell for an electronic rangefinder, including a top shell and a bottom shell. The top shell is recessed inward to form an upward-opening mounting cavity, and the bottom shell is recessed inward to form an upward-opening receiving cavity. The edge of the top shell is recessed inward to form a first sealing groove, and the edge of the bottom shell is recessed inward to form a second sealing groove. A sealing ring for achieving a sealing and waterproof function is installed between the first sealing groove and the second sealing groove. The sealing ring seals the gap between the top shell and the bottom shell. The inner wall of the bottom shell protrudes outward to form a semi-circular protrusion. The interior of the top shell protrudes outward and extends upward to form a fixing part. One end of the sealing ring extends to form a contact part that fits tightly with the first sealing groove, and another end of the sealing ring extends to form a locking part that fits tightly with the second sealing groove. The two sides of the sealing ring are recessed inward to form limiting grooves that fit tightly with the protrusions.

[0007] Furthermore, the bottom shell has several hollow fixed columns fixedly installed inside, and the top shell has several solid sleeve rods fixedly installed inside, with the sleeve rods inserted into the fixed columns.

[0008] Furthermore, the inner wall of the bottom shell is provided with a mounting groove for installing a power interface, and a waterproof ring for sealing and waterproofing the power interface is installed inside the mounting groove.

[0009] Furthermore, the sealing ring is made of silicone.

[0010] Furthermore, both the top shell and the bottom shell include a hard rubber layer and a soft rubber layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The sealed and waterproof housing of the electronic rangefinder of this utility model, by forming a first sealing groove and a second sealing groove on the edges of the top and bottom shells respectively, and installing a sealing ring, can fit tightly in the first and second sealing grooves, effectively sealing the gap between the top and bottom shells, thereby significantly improving the sealing and waterproof performance of the electronic rangefinder housing, protecting the internal electronic components from water damage. One end of the sealing ring extends to form a contact part that fits tightly with the first sealing groove, and the other end extends to form a locking part that fits tightly with the second sealing groove, ensuring that the sealing ring can be firmly installed between the first and second sealing grooves. The limiting grooves formed by the inward indentation on both sides of the sealing ring fit tightly with the semi-circular protrusion on the inner wall of the bottom shell, preventing the sealing ring from loosening or falling off during use, improving the firmness of the sealing ring, and making the installation of the sealing ring more secure.

Detailed Implementation

[0020] 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.

[0021] like Figures 1-6As shown, the electronic rangefinder has a sealed and waterproof housing, including a top shell 1 and a bottom shell 3. The top shell 1 is recessed inward to form an upward-opening mounting cavity 9 for mounting a lithium battery. The bottom shell 3 is recessed inward to form an upward-opening receiving cavity 6 for mounting a main control circuit board. The main control circuit board is connected to the lithium battery via wires. The edge of the top shell 1 is recessed inward to form a first sealing groove 8, and the edge of the bottom shell 3 is recessed inward to form a second sealing groove 7. A sealing device is installed between the first sealing groove 8 and the second sealing groove 7. A waterproof sealing ring 2 seals the gap between the top shell 1 and the bottom shell 3. The inner wall of the bottom shell 3 protrudes outward to form a semi-circular protrusion 16. The interior of the top shell 1 protrudes outward and extends upward to form a fixing part 13. One end of the sealing ring 2 extends to form a contact part 12 that fits tightly with the first sealing groove 8. One end of the sealing ring 2 extends to form a locking part 15 that fits tightly with the second sealing groove 7. The two sides of the sealing ring 2 are recessed inward to form limiting grooves 14 that fit tightly with the protrusion 16.

[0022] The bottom shell 3 has several hollow fixing posts 5 fixedly installed inside, and the top shell 1 has several solid sleeve rods 4 fixedly installed inside. The sleeve rods 4 are inserted into the fixing posts 5. The combination of the hollow fixing posts 5 inside the bottom shell 3 and the solid sleeve rods 4 inside the top shell 1 not only simplifies the assembly process, but also enhances the connection stability between the top shell 1 and the bottom shell 3 by inserting the sleeve rods 4 into the fixing posts 5. The inner wall of the bottom shell 3 has a mounting groove 17 for installing a power interface. The mounting groove 17 is equipped with a sealant for sealing the power interface. The waterproof ring 18 and the sealing ring 2 are made of silicone. The top shell 1 and the bottom shell 3 both include a hard rubber layer 10 and a soft rubber layer 11. The hard rubber layer 10 is made of ABS+PC material, which is a mixture of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS). The hard ABS+PC combines the flexibility of PC and the hardness of ABS, which enables it to withstand greater impact and has a certain scratch resistance. It has good impact resistance and can effectively absorb impact energy to provide better protection. The soft rubber layer 11 is made of TPE material, which has high elasticity, high strength and high resilience.

[0023] The sealed and waterproof housing of the electronic rangefinder in this embodiment uses a first sealing groove 8 and a second sealing groove 7 formed on the edges of the top shell 1 and the bottom shell 3, respectively, and a sealing ring 2 is installed thereon. The sealing ring 2 can fit tightly in the first sealing groove 8 and the second sealing groove 7, effectively sealing the gap between the top shell 1 and the bottom shell 3, thereby significantly improving the sealing and waterproof performance of the electronic rangefinder housing and protecting the internal electronic components from water damage. One end of the sealing ring 2 extends to form a contact part 12 that fits tightly in the first sealing groove 8, and the other end extends to form a locking part 15 that fits tightly in the second sealing groove 7, ensuring that the sealing ring 2 can be firmly installed between the first sealing groove 8 and the second sealing groove 7. The limiting grooves 14 formed by the inward indentation on both sides of the sealing ring 2 fit tightly in the semi-circular protrusions 16 on the inner wall of the bottom shell 3, preventing the sealing ring 2 from loosening or falling off during use, improving the firmness of the sealing ring 2, and making the installation of the sealing ring 2 more secure.

[0024] After installing the main control circuit board and lithium battery, prepare to install the top shell 1 and bottom shell 3. First, ensure that all components (top shell 1, bottom shell 3, sealing ring 2, etc.) are ready and in good condition, without damage or missing parts. Then assemble them. Apply glue to the first sealing groove 8 of the top shell 1 and the second sealing groove 7 of the bottom shell 3. Install the sealing ring 2 in the first sealing groove 8, and apply glue to the top shell 1 and bottom shell 3 again. Align the sleeve 4 of the top shell 1 with the fixing post 5 of the bottom shell 3 and gently insert it, ensuring that the sleeve 4 is fully inserted into the fixing post 5. Press firmly to install the top shell 1 completely with the bottom shell 3, so that one end of the sealing ring 2 is bonded to the first sealing groove 8 and the other end of the sealing ring 2 is bonded to the second sealing groove 7. The sealing ring 2 seals the gap between the top shell 1 and the bottom shell 3 to prevent water from entering.
