Description

Technical Field

[0001] This utility model relates to the field of display screen fixing technology, and in particular to a display screen fixing device. Background Technology

[0002] Currently, with the continuous development and application of medical devices, more and more devices are equipped with displays as operating media. These displays, as the core control interface of the devices, are typically used to display information, operating settings, and provide feedback on user commands. Therefore, the stability and protection of the displays are crucial for the normal use of medical devices. During device use, operators usually need to perform regular maintenance and cleaning, during which liquid cleaning agents may come into contact with the display and its surrounding structure. Without effective protective measures, liquids may seep into the device through the gaps between the display and the mounting frame, affecting the device's performance or even causing malfunction. Therefore, existing technologies typically employ two main fixing methods to prevent liquid penetration.

[0003] The current method uses rigid compression fixing, which means that the display screen is firmly fixed to the frame by mechanical force. This method can usually ensure the stability of the fixation, but its disadvantage is that if too much or uneven force is applied during the assembly process, it can easily lead to damage to the display screen, especially during mass production and assembly, where the damage rate is high, thereby increasing production and maintenance costs.

[0004] Therefore, how to ensure the stability of the display screen while simplifying the later maintenance process and reducing the risk of damage during assembly has become a major technical challenge in the design of medical devices. Utility Model Content

[0005] The main purpose of this utility model is to propose a display screen fixing device, which aims to solve the problem of how to ensure the stability of the display screen while simplifying the later maintenance process and reducing the risk of damage during assembly.

[0006] To achieve the above objectives, this utility model proposes a display screen fixing device for fixing a display screen, including a fixing mechanism, which includes a fixing frame, a tensioning adapter plate, and fasteners.

[0007] The tensioning adapter plate is provided with a cantilever structure, and the tensioning adapter plate is connected to the side of the display screen through the cantilever structure;

[0008] The tensioning adapter plate and the fixing frame are connected to the back of the display screen by the fasteners, and the tensioning adapter plate presses the display screen and the fixing frame together by the cantilever structure.

[0009] In one embodiment, the fastener includes a sleeve and a fastening pin. The tensioning adapter plate and the fixing frame are sleeved on the outside of the sleeve. One end of the fastening pin passes through the inside of the sleeve and is fixed to the display screen. The other end of the fastening pin is used to limit the tensioning adapter plate and the fixing frame.

[0010] In one embodiment, the tensioning adapter plate is provided with a support frame, and the cantilever structure is provided with a folding arm. The folding arm includes a folding upper arm and a folding lower arm. The folding upper arm is connected to the side of the display screen, and the folding lower arm is integrally connected to the support frame.

[0011] In one embodiment, the length of the folding upper arm is greater than the length of the folding lower arm.

[0012] In one embodiment, a limiting protrusion is provided at one end of the folding upper arm, and a limiting groove corresponding to the limiting protrusion is provided on the support frame, with the limiting protrusion located in the limiting groove.

[0013] In one embodiment, the end of the folding upper arm connected to the display screen is provided with a first fixing hole, the display screen is provided with a second fixing hole corresponding to the first fixing hole, and the fixing mechanism is also provided with a fixing member, which passes through and fixes the first fixing hole and the second fixing hole.

[0014] In one embodiment, the tensioning adapter plate is further provided with a clearance hole, which is located on the support frame.

[0015] In one embodiment, the display screen fixing device further includes a seal located between the display screen and the fixing frame.

[0016] In one embodiment, the display screen is provided with a positioning component, the tensioning adapter plate is provided with an opening corresponding to the positioning component, and the positioning component is placed in the opening.

[0017] In one embodiment, at least two cantilever structures are provided.

[0018] This invention employs a dual-fixing system of a tensioning adapter plate and fasteners to secure the display screen. The fasteners sequentially tighten the display screen, the tensioning adapter plate, and the fixing frame. The tensioning adapter plate, through a cantilever structure, presses the display screen against the fixing frame. This cantilever structure maintains continuous tension, ensuring the display screen and the fixing frame are tightly bonded together. This prevents the adhesive from failing and the seal from deteriorating over time. Furthermore, because the fasteners do not directly act on the display screen during assembly, excessive tightening force will not damage the display screen. This ensures the stability of the display screen while simplifying subsequent maintenance procedures and reducing the risk of damage during assembly. Attached Figure Description

[0034] This utility model proposes a display screen fixing device.

[0035] In the embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 As shown, the display screen fixing device is used to fix the display screen 2, including a fixing mechanism 1, which includes a fixing frame 11, a tensioning adapter plate 12 and fasteners 13;

[0036] The tensioning adapter plate 12 is provided with a cantilever structure 121, and the tensioning adapter plate 12 is connected to the side of the display screen 2 through the cantilever structure 121;

[0037] The tensioning adapter plate 12 and the fixing frame 11 are connected to the back of the display screen 2 by the fastener 13. The tensioning adapter plate 12 presses the display screen 2 and the fixing frame 11 together by the cantilever structure 121.

[0038] This utility model employs a dual-fixing mechanism of a tensioning adapter plate 12 and fasteners 13 to secure the display screen 2. The fasteners 13 sequentially tighten the display screen 2, the tensioning adapter plate 12, and the fixing frame 11. The tensioning adapter plate 12 presses the display screen 2 against the fixing frame 11 via a cantilever structure 121. The cantilever structure 121 can maintain continuous tension, ensuring that the display screen and the fixing frame 11 are tightly attached together, preventing the adhesive from failing and the seal from failing over time. Furthermore, during assembly, because the fasteners 13 do not directly act on the display screen 2, there is no risk of damage to the display screen 2 due to excessive tightening force. This ensures the stability of the display screen 2 while simplifying the subsequent maintenance process and reducing the risk of damage during assembly.

[0039] The fastener 13 includes a sleeve 131 and a fastening nail 132. The tensioning adapter plate 12 and the fixing frame 11 are sleeved on the outside of the sleeve 131. One end of the fastening nail 132 passes through the inside of the sleeve 131 and is fixed to the display screen 2. The other end of the fastening nail 132 is used to limit the tensioning adapter plate 12 and the fixing frame 11.

[0040] The fastening pin 132 can be a rivet, screw, or other nail. By fixing one end of the fastening pin 132 to the display screen 2 and limiting the tensioning adapter plate 12 and the fixing frame 11 at the other end, the stability of the display screen 2 during use can be ensured, preventing loosening or displacement caused by external force or vibration. The combination design of the sleeve 131 with the tensioning adapter plate 12 and the fixing frame 11 makes the installation of the fastening pin 132 more precise and can effectively prevent errors caused by component misalignment. This design combines the cooperation of multiple components. Through the cooperation of the sleeve 131 and the fastening pin 132, the installation process is simpler, the installation efficiency is improved, and the difficulty of manual operation is reduced. The design of the sleeve 131 and the fastening pin 132 makes the overall structure more compact, reduces space occupation, and improves the overall performance and reliability of the system.

[0041] The tensioning adapter plate 12 is provided with a support frame 122, and the cantilever structure 121 is provided with a folding arm 1211, such as Figure 6 As shown, the folding arm 1211 includes a folding upper arm 12111 and a folding lower arm 12112. The folding upper arm 12111 is connected to the side of the display screen 2, and the folding lower arm 12112 is integrally connected to the support frame 122. The tensioning adapter plate 12 is provided with a support frame 122, which makes the entire structure more stable and can effectively support the display screen 2, preventing the display screen 2 from shaking or tilting due to external forces.

[0042] The design of the folding arm 1211 provides adjustable flexibility. Folding arms 1211 are located on both sides of the display screen 2, allowing for adjustment of the screen's angle or position as needed, providing a more user-friendly experience. The connection between the folding upper arm 12111 and the side of the display screen 2 ensures the stability and robustness of the folding arm 1211. The cantilever structure 121 possesses a certain degree of elastic deformation performance, thus enabling the folding arm 1211 to have a tensioning function. Figure 3 As shown, the assembly consisting of the display screen 2 and the tensioning adapter plate 12 is fixed to the fixed frame 11 by fasteners 13, simultaneously generating a downward tensile force F1. During this fixing, the tensioning adapter plate 12, due to its tightening, causes the cantilever structure 121 to undergo elastic deformation. Since the display screen 2 and the folding arm 1211 are fixed by the fasteners 13, they are equivalent to a rigid body. During this deformation, the display screen 2 experiences a downward tensile force F2 due to the compression of the folding arm 1211. Under the action of this tensile force F2, the display screen 2 and the fixed frame 11 are tightly fitted together. The integrated design of the folding arm 1211 and the support frame 122 improves the overall structural compactness while also providing support and adjustment functions at different angles to adapt to different display needs.

[0043] The length of the folding upper arm 12111 is greater than the length of the folding lower arm 12112. The longer folding upper arm 12111 can effectively distribute more weight and enhance the load-bearing capacity of the structure.

[0044] One end of the folding upper arm 12111 is provided with a limiting protrusion 121111, and the support frame 122 is provided with a limiting groove 1221 corresponding to the limiting protrusion 121111. The limiting protrusion 121111 is located in the limiting groove 1221. The cooperative design of the limiting protrusion 121111 and the limiting groove 1221 effectively limits the range of motion of the folding upper arm 12111, preventing the folding upper arm 12111 from bending or deforming due to the excessive weight of the display screen 2. The precise cooperation between the limiting protrusion 121111 and the limiting groove 1221 can ensure the stability of the display screen 2 during installation, avoiding instability caused by loosening or displacement. By limiting the range of motion of the folding upper arm 12111, the weight of the display screen 2 can be effectively distributed, reducing the load concentrated on the folding arm 1211, improving the load-bearing capacity of the overall structure, and preventing damage to the folding arm 1211 due to excessive load.

[0045] like Figure 5As shown, the folding upper arm 12111 is provided with a first fixing hole 121112 at one end connected to the display screen 2, and the display screen 2 is provided with a second fixing hole 21 corresponding to the first fixing hole 121112. The fixing mechanism 1 is also provided with a fixing member 14, which passes through and fixes the first fixing hole 121112 and the second fixing hole 21.

[0046] In this embodiment, the fixing member 14 can be a screw. The folding upper arm 12111 and the display screen 2 are fixed by the cooperation of the first fixing hole 121112 and the second fixing hole 21, and the fixing member 14 passes through to fix them. This ensures that the connection between the folding upper arm 12111 and the display screen 2 is more secure, and avoids loosening or falling off due to external force or vibration. The fixing member 14 can effectively ensure a stable connection between the folding upper arm 12111 and the display screen 2, and reduce safety hazards caused by unstable connection during use, such as the display screen 2 tilting, shaking or falling off. Through the cooperative design of the first fixing hole 121112, the second fixing hole 21 and the fixing member 14, the fixing process is simpler and more direct, and users can complete the installation operation more easily. When maintenance is needed, disassembly is also convenient, saving time and labor intensity. The design of the fixing member 14 passing through and fixing the first and second fixing holes 21 helps to distribute the weight of the display screen 2 evenly, avoid concentrated load, reduce the stress of a single connection point, and improve the durability and stability of the overall structure.

[0047] The tensioning adapter plate 12 is also provided with a clearance hole 123, which is located on the support frame 122. The design of the clearance hole 123 allows other components to flexibly avoid interference with other structures, provides more adjustment space, enhances the adaptability and flexibility of the entire system, avoids unnecessary contact and friction between components, reduces wear and damage between components, extends the service life of the entire system, and makes components easier to disassemble and replace, facilitating later maintenance and repair, and reducing disassembly difficulties caused by component interference.

[0048] like Figure 7 , Figure 8As shown, the display screen fixing device also includes a sealing element 3. The sealing element 3 is located between the display screen 2 and the fixing frame 11. It can effectively prevent external substances such as dust, moisture, and dirt from entering the interior of the display screen 2, providing better protection, extending the service life of the display screen 2, and reducing environmental damage to the display screen 2. The sealing element 3 can seal the gap between the display screen 2 and the fixing frame 11, effectively blocking the intrusion of moisture and dust. It is particularly suitable for equipment that needs to be used in humid or dusty environments, improving its waterproof and dustproof performance, replacing the traditional glue sealing method. Using the sealing element 3, disassembly is convenient during maintenance. The sealing element 3 can also alleviate any gaps or contact friction that may exist between the display screen 2 and the fixing frame 11, reducing vibration and noise, and improving the stability and user experience of the display screen 2. This is especially important in environments with movement or vibration. Through the buffering effect of the sealing element 3, the direct impact of external pressure on the display screen 2 can be reduced, protecting the display screen 2 from damage caused by impact or external force. Especially during transportation or use, the sealing element 3 can ensure that the contact surface between the display screen 2 and the fixing frame 11 is completely sealed, preventing liquid or air penetration, further improving the durability and long-term stability of the equipment, especially when used in harsh environments.

[0049] The display screen 2 is provided with a positioning component 22, and the tensioning adapter plate 12 is provided with an opening 124 corresponding to the positioning component 22, with the positioning component 22 placed in the opening 124. The cooperative design of the positioning component 22 and the opening 124 ensures precise alignment between the display screen 2 and the tensioning adapter plate 12, helping to ensure accurate positioning of the display screen 2 and preventing poor assembly or malfunction due to inaccurate positioning. The design of the positioning component 22 and the opening 124 reduces frequent adjustments and unnecessary friction to the display screen 2, avoiding wear caused by frequent operation, thereby helping to extend the service life of the display screen 2.

[0050] At least two cantilever structures 121 are provided, and each cantilever structure 121 contains at least one folding arm 1211. In this embodiment, two cantilever structures 121 are provided, and two folding arms 1211 are provided in each cantilever structure 121.

[0051] By setting at least two cantilever structures 121, each containing multiple folding arms 1211, the load can be effectively distributed, greatly improving the stability and load-bearing capacity of the entire structure. This avoids deformation or damage to a single cantilever structure 121 due to excessive load. The design of multiple cantilever structures 121 increases the balance and stability of the overall structure, reduces uneven stress caused by a single cantilever structure 121, and improves the stability of the equipment in dynamic or static environments. The load borne by each folding arm 1211 is relatively light, which helps to reduce wear and damage to individual components, extend the service life of the overall equipment, and improve durability.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
