Technical Field

[0001] This utility model relates to the field of shell structure technology, and in particular to a shell structure and a safety warning device. Background Technology

[0002] Currently, many devices require housing structures, such as safety warning devices for working at heights. However, most existing housing structures have relatively simple designs, leading to the following problems: 1) When installed on other workpieces (e.g., installing the housing structure of a safety warning device onto a rope used for working at heights), it can only be adapted to specific types or specifications of workpieces, resulting in significant limitations during assembly. 2) The housing structure presents many inconveniences when maintaining internal electronic components. The housing cover is generally designed as a single piece; if internal electronic components malfunction or need replacement, the entire housing cover must be removed, sometimes requiring the use of special tools. This is not only time-consuming and labor-intensive, but also prone to damaging the housing structure and electronic components during disassembly and reinstallation, affecting the performance and reliability of the equipment. Summary of the Invention

[0009] Preferably, the main board is used to mount the main circuit board of electronic components; A mounting plate is provided on the second support wall that is in contact with the second housing cover. The mounting plate is used to mount the functional circuit board in the electronic component. A placement slot is provided between the mounting plate and its corresponding first support wall, and the placement slot is used to install the battery in the electronic component. The other of the first support walls is used to mount the switch circuit board in the electronic components.

[0010] Preferably, the first cover includes a first L-shaped cover body and two first cover walls disposed on opposite sides of the first L-shaped cover body; one end of the first L-shaped cover body is detachably connected to the main body shell, and the other end of the first L-shaped cover body and the two first cover walls are in close contact with the main body shell; The second cover includes a second L-shaped cover body and two second cover walls disposed on opposite sides of the second L-shaped cover body; one end of the second L-shaped cover body is detachably connected to one end of the first L-shaped cover body, and the other end of the second L-shaped cover body and the two second cover walls are all in close contact with the main body shell.

[0014] The outer shell structure provided in this embodiment features a fixing groove on the main shell. A locking assembly, detachably mounted on the main shell, securely locks the first workpiece into the fixing groove, thus assembling the outer shell structure onto the first workpiece. The fixing groove design is versatile, adaptable to different types or specifications of first workpieces, reducing limitations during assembly. This ensures the outer shell structure is reliably mounted on the first workpiece (e.g., mounting the outer shell structure of a safety warning device onto a rope used for high-altitude operations), preventing displacement or loosening due to vibration, collision, or other factors, thereby guaranteeing the reliability of the outer shell structure assembly.

[0015] The entire housing structure consists of a main shell, a first cover, and a second cover, forming a relatively enclosed space that provides excellent physical protection for the electronic components installed inside.

The locking assembly, the first cover, and the second cover all use detachable connections, such as fasteners (bolts) or snap-fit ​​structures. When assembling or removing the housing structure from the first workpiece, simply disassembling the locking assembly is sufficient for easy operation. When maintenance or replacement of electronic components is required, the first and second covers can be easily removed for quick access to the internal components.

This multi-directional, multi-space division allows for rational layout and installation based on the shape, size, and functional requirements of electronic components, improving space utilization efficiency. Because the outer casing structure is detachable, individual inspection and repair of electronic components within each accommodating space are convenient during maintenance. During installation, the first cover is detachably connected to the main body, and the second cover is detachably connected to the first cover. This design allows for easy access to the internal electronic components for inspection and maintenance when a component malfunctions, simply by opening the second cover, without disassembling the entire outer casing structure. This reduces maintenance complexity and workload, improving equipment maintenance efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] This utility model embodiment provides a shell structure, see reference Figure 1 and Figure 2 The housing structure includes a main shell 1, a locking assembly 2, a first cover 3, and a second cover 4. The main shell 1 is provided with a fixing groove 5 for accommodating a first workpiece. The locking assembly 2 is detachably installed on the main shell 1 to lock the first workpiece in the fixing groove 5. The first cover 3 is detachably connected to the main shell 1 and cooperates with the left side of the main shell 1 to form a first accommodating space arranged in a first direction and a second accommodating space arranged in a second direction. The second cover 4 is detachably connected to the first cover 3 and cooperates with the right side of the main shell 1 to form a third accommodating space arranged in a first direction and a fourth accommodating space arranged in a second direction. The first, second, third, and fourth accommodating spaces are all used to install electronic components 6.

[0024] The first direction and the second direction are two mutually perpendicular directions. For example, the first direction is the front-to-back direction of the outer shell structure, and the second direction is the left-to-right direction of the outer shell structure. The outer shell structure can be the outer shell structure of a safety warning device, which is installed on a rope when the safety warning device is used in high-altitude operations.

[0025] As an example, the housing structure includes a main shell 1, a locking assembly 2, a first cover 3, and a second cover 4. A fixing groove 5 is provided on the main shell 1. In conjunction with the locking assembly 2, which is detachably mounted on the main shell 1, the first workpiece can be securely locked into the fixing groove 5, thus assembling the housing structure onto the first workpiece. The design of the fixing groove 5 has a certain degree of versatility, adapting to different types or specifications of first workpieces, reducing the limitations of the housing structure during assembly. This ensures that the housing structure is reliably installed on the first workpiece (e.g., installing the housing structure of a safety warning device onto a rope used for high-altitude operations), preventing displacement or loosening due to vibration, collision, or other factors, thereby guaranteeing the reliability of the housing structure assembly.

[0026] The entire outer casing structure consists of the main casing 1, the first cover 3, and the second cover 4, forming a relatively enclosed space that provides excellent physical protection for the electronic components 6 installed inside. This prevents dust, moisture, and debris from entering, avoiding corrosion and damage to the electronic components 6 from the external environment and extending their service life. The locking assembly 2, the first cover 3, and the second cover 4 are all detachable, for example, connected by fasteners (bolts) or by snap-fit ​​structures. When assembling the outer casing structure onto or removing it from the first workpiece, only the locking assembly 2 needs to be removed for easy operation. When it is necessary to inspect or replace the electronic components 6, the first cover 3 and the second cover 4 can be easily removed for quick access to the internal components. This design greatly improves the operability and maintenance efficiency of the equipment, reduces downtime, and lowers operating costs.

[0027] The first cover 3 cooperates with the main body 1 to form a first accommodating space arranged along a first direction and a second accommodating space arranged along a second direction; the second cover 4 cooperates with the main body 1 to form a third accommodating space arranged along the first direction and a fourth accommodating space arranged along the second direction. This multi-directional, multi-space division method can make reasonable layout and installation according to the shape, size and functional requirements of the electronic components 6, thus improving space utilization efficiency.

[0028] Because the outer casing is designed to be detachable, individual inspection and repair of the electronic components 6 within each compartment are easily possible during maintenance. During installation, the first cover 3 is detachably connected to the main casing 1, and the second cover 4 is detachably connected to the first cover 3. This design allows for easy access to the internal electronic components 6 for inspection and maintenance simply by opening the second cover 4, without disassembling the entire outer casing. This reduces the complexity and workload of maintenance, and improves the efficiency of equipment maintenance.

[0029] In one embodiment, reference is made to Figure 2The locking assembly 2 includes a fixing strap and a locking cover 21; at least one binding ring 7 is provided on the groove wall of the fixing groove 5; the fixing strap passes through the binding ring 7 and is used to bind the first workpiece in the fixing groove 5; the locking cover 21 is detachably installed on the main body shell 1 and is used to lock the first workpiece in the fixing groove 5.

[0030] As an example, the locking assembly 2 includes a fixing strap and a locking cover 21. At least one binding ring 7 is provided on the groove wall of the fixing groove 5. During assembly, the fixing strap is first threaded through the binding ring 7, and then the first workpiece is bound to the fixing groove 5 by the fixing strap. This allows for binding force to be applied to the first workpiece from multiple directions, effectively preventing horizontal displacement of the workpiece within the fixing groove 5. The locking cover 21 is detachably mounted on the main housing 1, forming a vertical pressing effect on the fixing strap. Working in conjunction with the fixing strap, it achieves double locking of the first workpiece. This double locking mechanism greatly enhances the stability of the housing structure, ensuring that the housing structure will not loosen or detach even when the equipment is subjected to significant external impact or operates in a severely vibrating environment, thus guaranteeing the normal operation of the entire equipment.

[0031] The operation of inserting the fixing strap into the binding ring 7 is relatively simple, requiring no complex tools or professional skills, allowing operators to quickly complete the initial binding of the first workpiece. The locking cover 21 is detachable, typically requiring only simple clips, screws, or other connecting structures to connect and separate from the main shell 1. When assembling or removing the outer shell structure from the first workpiece, the locking cover 21 can be quickly removed and the fixing strap loosened, significantly shortening operation time and improving work efficiency. The design of the fixing strap and locking cover 21 considers reusability. The fixing strap is generally made of a material with a certain strength and flexibility (such as cable ties), maintaining good performance after multiple binding and loosening operations without breakage or deformation. The detachable installation structure of the locking cover 21 also ensures that it will not be damaged during repeated assembly and disassembly, enabling long-term stable use. The binding ring 7 allows the fixing strap to be flexibly adjusted according to the size of the first workpiece. For first workpieces of different thicknesses and lengths, a secure binding can be achieved simply by adjusting the length and tightness of the fixing strap within the binding ring 7. This flexibility allows the locking assembly 2 to be adapted to a variety of first workpieces, improving the versatility and applicability of the housing structure.

[0032] In one embodiment, reference is made to Figure 2 The groove wall of the fixed groove 5 is also provided with a plurality of anti-slip ribs 8, which are arranged at intervals along the length of the fixed groove 5 and abut against the first workpiece.

[0033] As an example, multiple anti-slip ribs 8 are also provided on the wall of the fixing groove 5. These ribs 8 are spaced apart along the length of the fixing groove 5 (i.e., the vertical direction of the outer shell structure) and abut against the first workpiece. The direct contact between the anti-slip ribs 8 and the first workpiece significantly increases the contact area and friction coefficient between the wall of the fixing groove 5 and the first workpiece, effectively preventing the first workpiece from sliding or displacing within the fixing groove 5 through friction. The spaced arrangement of the multiple anti-slip ribs 8 along the length of the fixing groove 5 forms multiple support points. These support points can evenly distribute the external force on the first workpiece, making the force on the first workpiece more balanced. Compared to single planar contact, multi-point support can better resist the tilting and torsion of the first workpiece, further improving the stability of the fixing. The anti-slip ribs 8 have a certain degree of elasticity, which can buffer vibration. When the first workpiece is subjected to vibration impact, the anti-slip ribs 8 can absorb and disperse some of the vibration energy, reducing the direct impact of vibration on the workpiece, thereby reducing wear caused by vibration. The spaced arrangement of multiple anti-slip ribs 8 can better adapt to first workpieces of different shapes. Regardless of whether the workpiece is a regular cylinder, square, or irregular shape, the anti-slip rib 8 can provide effective fixation by abutting against the surface of the first workpiece. This adaptability allows the fixing groove 5 to be used to fix various types of first workpieces, improving the versatility and flexibility of the equipment.

[0034] In one embodiment, reference is made to Figure 2 The locking cover 21 includes a locking cover body 211 and a top protrusion 212 disposed on the surface of the locking cover body 211; the locking cover body 211 is detachably mounted on the main body shell 1; the top protrusion 212 is embedded in the fixing groove 5 and abuts against the first workpiece.

[0035] As an example, the locking cover 21 includes a locking cover body 211 and a top protrusion 212. The top protrusion 212 is disposed on the surface of the locking cover body 211. The top protrusion 212 can be a columnar structure or a frame structure. In this example, it is a frame structure. The frame structure cooperates with the locking cover body 211 to form a receiving groove so that the first workpiece can be placed in the receiving groove. During installation, the locking cover body 211 is detachably installed on the main body shell 1. Specifically, a recess is provided on the main body shell 1, and the connecting part of the locking cover body 211 is embedded in the recess and fixed by bolts. The detachable installation of the locking cover body 211 on the main body shell 1 allows for quick assembly and disassembly of the locking cover 21 when assembling the outer shell structure onto the first workpiece or removing the outer shell structure from the first workpiece, greatly shortening the operation time and improving work efficiency. The top protrusion 212 is embedded in the fixing groove 5 and abuts against the first workpiece. This embedding structure enables the first workpiece to form a relatively tight connection with the locking cover 21 and the main shell 1, effectively preventing relative displacement between the outer shell structure and the first workpiece, thereby enhancing the stability of the entire structure.

[0036] In one embodiment, reference is made to Figure 2 and Figure 3 The main body shell 1 includes a main body plate 101, two first support walls 102 extending from opposite sides of the main body plate 101 in the same direction, and two second support walls 103 extending from the edge of the two first support walls 102 away from the main body plate 101 in opposite directions. The main body plate 101 and the two first support walls 102 cooperate to form a fixing groove 5, and a locking cover 21 is detachably installed on at least one second support wall 103. The first shell cover 3 is detachably connected to the main body plate 101 and fits against a first support wall 102, a second support wall 103 and a part of the main body plate 101 to form a first accommodating space and a second accommodating space. The second shell cover 4 is detachably connected to the first shell cover 3 and fits against another first support wall 102, another second support wall 103 and another part of the main body plate 101 to form a third accommodating space and a fourth accommodating space.

[0037] As an example, the main body shell 1 includes a main body plate 101, two first support walls 102, and two second support walls 103. The main body plate 101 serves as a reference. The two first support walls 102 are components extending from opposite sides of the main body plate 101 in the same direction, while the two second support walls 103 are components extending from the edges of the two first support walls 102 away from the main body plate 101 in opposite directions. The main body plate 101 and the two first support walls 102 cooperate to form a fixing groove 5, providing precise mounting positioning for the top protrusion 212 of the locking cover 21, directly limiting the displacement of the locking cover 21, and indirectly ensuring the stable contact state of the first workpiece. The main body plate 101, the two first support walls 102, and the two second support walls 103 cooperate to form a U-shaped structure, which not only enhances the structural strength of the main body shell 1 itself but also provides a clear assembly support surface for the locking cover 21, the first shell cover 3, and the second shell cover 4, ensuring that all components fit tightly and preventing loosening. The first cover 3 is detachably connected to the main body plate 101 and is fitted into a first support wall 102, a second support wall 103, and a portion of the main body plate 101, forming a first accommodating space and a second accommodating space. The second cover 4 is detachably connected to the first cover 3 and is fitted into another first support wall 102, another second support wall 103, and another portion of the main body plate 101, forming a third accommodating space and a fourth accommodating space. This arrangement allows for the separate storage of electronic components 6 with different functions, avoiding interference and signal interference between components. Moreover, when electronic components 6 in the third and fourth accommodating spaces malfunction, maintenance can be performed simply by opening the second cover 4, without disassembling the entire outer shell structure. This reduces the complexity and workload of maintenance and improves the efficiency of equipment maintenance. The fitted design of the cover to the main body shell 1 maximizes the use of the space around the main body shell 1, expanding the number of internally accommodating components without increasing the overall volume, thus meeting the requirements of equipment integration.

[0038] In one embodiment, reference is made to Figure 2 and Figure 3 The main body plate 101 is used to install the main circuit board 61 in the electronic component 6; the second support wall 103, which is in contact with the second cover 4, is provided with a mounting plate 104, which is used to install the functional circuit board 62 in the electronic component 6; a placement groove 105 is reserved between the mounting plate 104 and its corresponding first support wall 102, which is used to install the battery 63 in the electronic component 6; another first support wall 102 is used to install the switch circuit board 64 in the electronic component 6.

[0039] As an example, during installation, the main board 101 is used to mount the main circuit board 61 of the electronic component 6. Specifically, the main board 101 has a first mounting position (multiple first pillars), and the main circuit board 61 is mounted in the first mounting position, that is, the main circuit board 61 is mounted in the second accommodating space and the fourth accommodating space. A mounting plate 104 is provided on the second support wall 103 that is in contact with the second cover 4. The mounting plate 104 is used to mount the functional circuit board 62 of the electronic component 6. Specifically, the mounting plate 104 has a second mounting position (multiple second pillars), and the functional circuit board 62 is mounted in the second mounting position, that is, the functional circuit board 62 is mounted in the third accommodating space. A placement groove 105 is reserved between the mounting plate 104 and its corresponding first support wall 102. The placement groove 105 is used to mount the battery 63 of the electronic component 6. Another first support wall 102 is used to install the switch circuit board 64 in the electronic component 6. Specifically, a third mounting position (multiple third pillars) is provided on the other first support wall 102. The switch circuit board 64 is installed in the third mounting position, that is, the switch circuit board 64 is installed in the first accommodating space.

[0040] The main circuit board 61, functional circuit board 62, and switch circuit board 64 are installed in different accommodating spaces, physically separated from each other. This layout effectively avoids electromagnetic interference generated when different circuit boards are working, ensuring signal stability for each circuit module and reducing the risk of failure. The battery 63 is independently installed through the placement slot 105, maintaining a distance from each circuit board. This prevents the battery 63 from overheating and affecting the circuit boards, and also avoids damage to the circuits due to battery leakage, improving equipment safety. The installation locations of each electronic component 6 are clearly zoned. When a fault occurs, the installation area of ​​the corresponding circuit board or component can be quickly located based on the fault symptoms, without the need for complete disassembly and searching, shortening troubleshooting time. For example, when replacing the battery 63, only the second cover 4 needs to be removed, without touching other core components, reducing maintenance difficulty and minimizing the risk of secondary damage to other components during maintenance.

[0041] In one embodiment, reference is made to Figure 2The first cover 3 includes a first L-shaped cover body 31 and two first cover walls 32 disposed on opposite sides of the first L-shaped cover body 31; one end of the first L-shaped cover body 31 is detachably connected to the main body shell 1, and the other end of the first L-shaped cover body 31 and the two first cover walls 32 are in close contact with the main body shell 1; the second cover 4 includes a second L-shaped cover body 41 and two second cover walls 42 disposed on opposite sides of the second L-shaped cover body 41; one end of the second L-shaped cover body 41 is detachably connected to one end of the first L-shaped cover 31, and the other end of the second L-shaped cover body 41 and the two second cover walls 42 are in close contact with the main body shell 1.

[0042] As an example, the first cover 3 includes a first L-shaped cover body 31 and two first cover walls 32. The two first cover walls 32 are two components located on opposite sides of the first L-shaped cover body 31. The other end of the first L-shaped cover body 31 and the two first cover walls 32 are fully fitted to the main body shell 1; the second cover 4 is similar. This design allows the cover to form a "wrap-around" contact with the main body shell 1, significantly reducing gaps and effectively preventing dust, moisture, impurities, and other foreign objects from entering the internal storage space, protecting components such as electronic components 6. The shape of the L-shaped cover can precisely match the structural contours of the main body shell 1's support walls, main body plate 101, etc., avoiding local sealing failures caused by shape mismatch and ensuring the integrity of the overall protection. One end of the first L-shaped cover 31 is detachably locked to the main shell 1, while the other end and cover wall are positioned by fitting together. One end of the second L-shaped cover 41 is detachably connected to the other end of the first L-shaped cover 31. Specifically, a pin is provided at the other end of the first L-shaped cover 31, and a socket is provided at one end of the second L-shaped cover 41. The pin is inserted into the socket and connected by bolts. The other end and cover wall of the second L-shaped cover 41 fits against the main shell 1. This dual constraint of "locking + fitting" restricts the freedom of movement of the cover and prevents loosening or displacement during use. The first cover 3 is detachably connected to the main shell 1, and the second cover 4 is detachably connected to the first cover 3. During maintenance, the corresponding cover can be removed individually as needed, without disassembling the entire device, allowing quick access to components within the target storage space and improving maintenance efficiency.

[0043] This utility model embodiment provides a safety warning device, referencing... Figure 1 , Figure 2 and Figure 3 It includes electronic components 6 and a housing structure; the housing structure is used to mount on the first workpiece; the electronic components 6 include a main circuit board 61, a switch circuit board 64, a battery 63, and a functional circuit board 62; the main circuit board 61 is mounted in the second and fourth accommodating spaces, the switch circuit board 64 is mounted in the first accommodating space, and the battery 63 and the functional circuit board 62 are mounted in the third accommodating space.

[0044] As an example, the safety warning device includes electronic components 6 and a housing structure. The housing structure is used for mounting on a first workpiece, specifically on a rope used for high-altitude operations. A fixing groove 5 is provided on the main body 1 of the housing structure. In conjunction with a locking assembly 2 detachably mounted on the main body 1, the rope can be securely locked into the fixing groove 5, thus assembling the housing structure onto the rope. The design of the fixing groove 5 is versatile, adaptable to different types or specifications of ropes, reducing the limitations of the housing structure during assembly. This ensures that the housing structure is securely mounted on the rope and will not shift or loosen due to vibration, collision, or other factors, thereby guaranteeing the reliability of the housing structure assembly.

The main circuit board 61 is installed in the second and fourth accommodating spaces, the switch circuit board 64 is installed in the first accommodating space, and the battery 63 and functional circuit board 62 are installed in the third accommodating space. The main circuit board 61, functional circuit board 62, and switch circuit board 64 are physically separated from each other, effectively avoiding electromagnetic interference generated by different circuit boards during operation, ensuring signal stability of each circuit module, and reducing the risk of failure. The battery 63 is independently installed through the placement slot 105, maintaining a distance from each circuit board. This prevents the battery 63 from overheating and affecting the circuit boards, and also avoids damage to the circuits due to battery leakage, improving equipment safety. The installation positions of each electronic component 6 are clearly defined, allowing for quick identification of the corresponding circuit board or component's installation area based on the fault symptoms in case of a fault, eliminating the need for complete disassembly and shortening troubleshooting time. For example, when replacing battery 63, only the second cover 4 needs to be removed, without touching other core components, reducing maintenance difficulty and minimizing the risk of secondary damage to other components during maintenance. Furthermore, the assembly of the main circuit board 61, switch circuit board 64, battery 63, and functional circuit board 62 within the housing structure, as well as the assembly of the housing mechanism and the rope, are independent of each other, ensuring that the installation of the rope will not affect the main circuit board 61, switch circuit board 64, battery 63, and functional circuit board 62.

[0046] In one embodiment, reference is made to Figure 2 and Figure 3 The main circuit board 61 is attached to the inner wall of the first cover 3 and the inner wall of the second cover 4.

[0047] As an example, the main circuit board 61 is in close contact with the inner wall of the first cover 3 and the inner wall of the second cover 4. This arrangement allows the sensor on the main circuit board 61 to be in close contact with the shell wall of the outer shell structure, reducing the influence of other components and ensuring that the sensor can perform its function to the maximum extent.

[0048] In one embodiment, the safety warning device further includes a switch button, an indicator light, and an audible sound; the switch button is mounted on a switch circuit board 64, and the button of the switch button protrudes through the first housing cover 3; the indicator light and the audible sound are arranged at intervals on the functional circuit board 62, and each of them corresponds one-to-one with the indicator light position and the audible sound position of the second housing cover 4.

[0049] As an example, the safety warning device also includes a switch button, indicator lights, and an audible alarm. During installation, the switch button is mounted on the switch circuit board 64, with the button protruding through the first cover 3. The first cover 3, being an externally visible structure of the safety warning device, clearly exposes the switch button's location, allowing users to quickly locate and operate it without searching, thus lowering the barrier to entry. The indicator lights and audible alarm are spaced apart on the functional circuit board 62, each corresponding to an indicator light position and an audible alarm position on the second cover 4, concentrating visual and auditory warning components in the same area to form an integrated "sound and light" warning combination. When the safety warning device triggers an alarm, the user can simultaneously perceive the warning information visually and audibly, enhancing the warning's recognizability and sense of urgency.

[0050] The safety warning device in this example is an intelligent double-hook safety belt alarm, applied to safety belts used in high-altitude operations. It provides dual protection and proactive early warning, and can monitor the locking status of the two safety hooks in real time. Through high-precision sensors, it can identify abnormal situations or violations such as the double hooks not being suspended, not being fastened, not being closed, or the double hooks being caught on the worker while climbing. It can be equipped with a built-in three-axis accelerometer and gyroscope to intelligently analyze the worker's posture. When it detects abnormal tilting (such as leaning back more than 30°) or rapid falling, it immediately triggers an audible and visual alarm. It also integrates temperature, humidity, and wind speed sensors, and automatically issues a warning when environmental parameters exceed safety thresholds (such as wind speed > level 8).
